Completion Surgery After Concomitant Chemoradiation in Locally Advanced Cervical Cancer: A Comprehensive Analysis of Pattern of Postoperative Complications

Definite Treatment Delay With Neoadjuvant Chemotherapy and Longitudinal Monitoring by Circulating Tumor DNA for Advanced Cervical Cancer During Pregnancy: A Case Series and Literature Review

BACKGROUND

Previous studies mainly concentrate on neoadjuvant chemotherapy (NACT) for delivery delay in FIGO Stage IB1-IIIB cervical cancer during pregnancy to prevent early preterm delivery while not affecting maternal outcome.

CASE

Here, we described two pregnant patients with FIGO Stage IIIC cervical cancer about their diagnosis, treatment, and outcome. Both patients underwent cesarean delivery, left enlarged lymph node dissection, and longitudinal monitoring by circulating tumor DNA. Our study suggested that pregnant patient was completely response to NACT, which was confirmed by ctDNA monitoring, followed by left pelvic enlarged lymph node dissection during cesarean section and adjuvant chemoradiotherapy postpartum. The infant grew normally, without any evidence of chemotherapy-related side effects after delivery.

CONCLUSION

In pregnant women with advanced cervical cancer, longitudinal ctDNA monitoring might be able to evaluate maternal response to NACT and confirm if delivery delay to optimize fetal outcome would compacting the maternal outcomes or not. Cervical cancer may not transmit across the placental barrier and so it is safe for delayed delivery until fetal maturity in utero during pregnancy.

The value of MRI in quantification of parametrial invasion and association with prognosis in locally advanced cervical cancer: the "PLACE" study

OBJECTIVE

This retrospective observational study aims to evaluate the association between the extent of parametrial invasion (PMI) and disease-free survival (DFS) and cancer-specific survival (CSS) in patients with locally advanced cervical cancer (LACC).

MATERIALS AND METHODS

This study included patients with LACC showing parametrial invasion at Magnetic Resonance Imaging (MRI). They were treated with neoadjuvant chemo-radiotherapy (CT/RT) before undergoing radical hysterectomy. The staging MRIs were reviewed retrospectively. Measurements of maximum PMI (PMImax) and parametrial length were taken bilaterally. After that, PMIratio was calculated by dividing PMImax by parametrial length. Analysis was conducted on homogeneous subsets of patients, grouped based on their pathological lymph nodal evaluation (N- and N+). Correlations between PMImax and PMIratio with DFS and CSS were evaluated in both the N- and N+ groups, employing univariable Cox regression analysis.

RESULTS

Out of 221 patients, 126 (57%) had non-metastatic lymph nodes (N-), while 95 (43%) had metastatic lymph nodes (N+). The median observation period for all these patients was 73 months (95% confidence interval [CI]: 66-77). The 5-year DFS and CSS probability rates were 75% and 85.7%, respectively, for the N- group and 54.3% and 73.6%, respectively, for the N+ group. A higher PMImax (hazard ratio [HR] = 1.09) and PMIratio (HR = 1.04) correlated with worse overall survival in patients in the N- group (p = 0.025 and p = 0.042). These parameters did not show a significant statistical association in the N+ group.

CONCLUSIONS

The degree of PMI evaluated on MRI affects outcome in N- patients with LACC.

CLINICAL RELEVANCE STATEMENT

The degree of MRI parametrial invasion affects disease-free survival and cancer-specific survival in patients with the International Federation of Gynecology and Obstetrics (FIGO) stage IIB cervical cancer. This MRI finding can be easily incorporated into routine clinical practice.

KEY POINTS

• Visual assessment of parametrial invasion on MRI was not significantly associated with prognosis in locally advanced cervical cancer (LACC). • A greater degree of parametrial invasion is associated with poorer disease-free survival and cancer-specific survival in patients with LACC without metastatic lymph node involvement. • The degree of parametrial invasion at MRI has no correlation with prognosis in LACC with metastatic lymph nodes.

Urinary, Gastrointestinal, and Sexual Dysfunctions after Chemotherapy, Radiotherapy, Radical Surgery or Multimodal Treatment in Women with Locally Advanced Cervical Cancer: A Multicenter Retrospective Study

BACKGROUND

Different strategies have been proposed for the treatment of locally advanced cervical cancer (LACC), with different impacts on patient's quality of life (QoL). This study aimed to analyze urinary, bowel, and sexual dysfunctions in a series of LACC patients who underwent chemotherapy, radiotherapy, radical surgery, or a combination of these treatments.

METHODS

Patients with LACC who underwent neoadjuvant radio-chemotherapy (NART/CT; n = 35), neoadjuvant chemotherapy (NACT; n = 17), exclusive radio-chemotherapy (ERT/CT; n = 28), or upfront surgery (UPS; n = 10) from November 2010 to September 2019 were identified from five oncological referral centers. A customized questionnaire was used for the valuation of urinary, gastrointestinal, and sexual dysfunctions.

RESULTS

A total of 90 patients were included. Increased urinary frequency (>8 times/day) was higher in ERT/CT compared with NACT/RT (57.1% vs. 28.6%; p = 0.02) and NACT (57.1% vs. 17.6%; p = 0.01). The use of sanitary pads for urinary leakage was higher in ERT/CT compared with NACT/RT (42.9% vs. 14.3%; p = 0.01) and NACT (42.9% vs. 11.8%; p = 0.03). The rate of reduced evacuations (<3 times a week) was less in UPS compared with NACT/RT (50% vs. 97.1%; p < 0.01), NACT (50% vs. 88.2, p < 0.01), and ERT/CT (50% vs. 96.4%; p < 0.01). A total of 52 women were not sexually active after therapy, and pain was the principal reason for the avoidance of sexual activity.

CONCLUSIONS

The rate and severity of urinary, gastrointestinal, and sexual dysfunction were similar in the four groups of treatment. Nevertheless, ERT/CT was associated with worse sexual and urinary outcomes.

Prognostic Value of Mandard's Tumor Regression Grade (TRG) in Post Chemo-Radiotherapy Cervical Cancer

In locally advanced cervical cancer (LACC), definitive chemo-radiotherapy is the standard treatment, but chemo-radiotherapy followed by surgery could be an alternative choice in selected patients. We enrolled 244 patients affected by LACC and treated with CT-RT followed by surgery in order to assess the prognostic role of the histological response using the Mandard scoring system. Results: A complete pathological response (TRG 0) was observed in 118 patients (48.4%), rare residual cancer cells (TRG2) were found in 49 cases (20.1%), increased number of cancer cells but fibrosis still predominating (TRG3) in 35 cases (14.3%), and 42 (17.2%) were classified as non-responders (TRG4-5). TRG was significantly associated with both OS (p < 0.001) and PFS (p < 0.001). The survival curves highlighted two main prognostic groups: TRG1-TRG2 and TRG3-TRG4-5. Main responders (TRG1-2) showed a 92% 5-year overall survival (5y-OS) and a 75% 5-year disease free survival (5y-DFS). Minor or no responders showed a 48% 5y-OS and a 39% 5y-DFS. The two-tiered TRG was independently associated with both DFS and OS in Cox regression analysis. Conclusion. We showed that Mandard TRG is an independent prognostic factor in post-CT/RT LACC, with potential benefits in defining post-treatment adjuvant therapy.

Human papillomavirus independent status on pathologic response and outcomes in locally advanced cervical cancer managed with chemoradiotherapy followed by surgery

OBJECTIVE

While human papillomavirus (HPV) has been shown to play a significant role in cervical cancer carcinogenesis (HPV associated cases), a considerable percentage of cervical cancers occur independently of HPV status (HPV independent).

METHODS

In this retrospective study of 254 locally advanced cervical cancer patients treated with chemoradiotherapy and radical surgery, HPV genotypes were determined using the Anyplex II HPV28 kit that uses multiplex, real time polymerase chain reaction technology. The primary endpoints of this study were to evaluate the complete response to chemoradiotherapy (pathologic complete response), the presence of microscopic (<3 mm, pathologic micro partial response, group 1) and macroscopic (>3 mm, pathologic macro partial response, group 2) residual carcinoma in the cervix, and the persistence of metastatic lymph nodes (group 3) in HPV independent cervical cancers. Secondary endpoints were evaluation of disease-free survival and overall survival.

RESULTS

Of 254 patients studied, 21 cases (8.3%) of cervical cancer were determined to be HPV independent. The percentage of pathologic complete response was found to be higher in the HPV associated group compared with the HPV independent group (p<0.001). In the HPV associated cervical cancer group, 5 year disease free survival was found to be 80.8% versus 59.9% in the HPV independent group (p=0.014). Overall survival was also higher in the HPV associated group (87.9%) compared with the HPV independent patients (69.4%) (p=0.023). In the multivariate analysis, the International Federation of Gynecology and Obstetrics (FIGO) stage and HPV genotypes maintained their relevant impact on pathologic complete response to chemoradiotherapy: FIGO stages IIIC1 and IIIC2 were associated with a 13-fold increased risk for the presence of metastatic lymph nodes compared with group 1 (p<0.001). HPV independent cervical cancers showed the highest risk for the development of macroscopic/stable disease (p=0.007), and persistence of metastatic lymph nodes (p=0.004) versus group 1, respectively.

CONCLUSIONS

This study showed that HPV status at diagnosis could be a relevant factor for clinical outcomes in locally advanced cervical cancer patients.

Hysterectomy with radiotherapy or chemotherapy or both for women with locally advanced cervical cancer

BACKGROUND

This is an update of the Cochrane Review published in Issue 4, 2015. Cervical cancer is one of the most frequent cause of death from gynaecological cancers worldwide. Many new cervical cancer cases in low-income countries present at an advanced stage. Standard care in Europe and the US for locally advanced cervical cancer (LACC) is chemoradiotherapy. In low-income countries, with limited access to radiotherapy, LACC may be treated with chemotherapy and hysterectomy. It is not certain if this improves survival. It is important to assess the value of hysterectomy with radiotherapy or chemotherapy, or both, as an alternative.

OBJECTIVES

To determine whether hysterectomy, in addition to standard treatment with radiotherapy or chemotherapy, or both, in women with LACC (Stage IB2 to III) is safe and effective compared with standard treatment alone.

SEARCH METHODS

We searched CENTRAL, MEDLINE via Ovid, Embase via Ovid, LILACS, trial registries and the grey literature up to 3 February 2022.

SELECTION CRITERIA

We searched for randomised controlled trials (RCTs) that compared treatments involving hysterectomy versus radiotherapy or chemotherapy, or both, in women with LACC International Federation of Gynecology and Obstetrics (FIGO) Stages IB2 to III.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We independently assessed study eligibility, extracted data and assessed the risk of bias. Where possible, we synthesised overall (OS) and progression-free (PFS) or disease-free (DFS) survival in a meta-analysis using a random-effects model. Adverse events (AEs) were incompletely reported and we described the results of single trials in narrative form. We used the GRADE approach to assess the certainty of the evidence.

MAIN RESULTS

From the searches we identified 968 studies. After deduplication, title and abstract screening, and full-text assessment, we included 11 RCTs (2683 women) of varying methodological quality. This update identified four new RCTs and three ongoing RCTs. The included studies compared: hysterectomy (simple or radical) with radiotherapy or chemoradiotherapy or neoadjuvant chemotherapy (NACT) versus radiotherapy alone or chemoradiotherapy (CCRT) alone or CCRT and brachytherapy. There is also one ongoing study comparing three groups: hysterectomy with CCRT versus hysterectomy with NACT versus CCRT. There were two comparison groups for which we were able to do a meta-analysis. Hysterectomy (radical) with neoadjuvant chemotherapy versus chemoradiotherapy alone Two RCTs with similar design characteristics (620 and 633 participants) found no difference in five-year OS between NACT with hysterectomy versus CCRT. Meta-analysis assessing 1253 participants found no evidence of a difference in risk of death (OS) between women who received NACT plus hysterectomy and those who received CCRT alone (HR 0.94, 95% CI 0.76 to 1.16; moderate-certainty evidence). In both studies, the five-year DFS in the NACT plus surgery group was worse (57%) compared with the CCRT group (65.6%), mostly for Stage IIB. Results of single trials reported no apparent difference in long-term severe complications, grade 3 acute toxicity and severe late toxicity between groups (very low-quality evidence). Hysterectomy (simple or radical) with neoadjuvant chemotherapy versus radiotherapy alone Meta-analysis of three trials of NACT with hysterectomy versus radiotherapy alone, assessing 571 participants, found that women who received NACT plus hysterectomy had less risk of death (OS) than those who received radiotherapy alone (HR 0.71, 95% CI 0.55 to 0.93; I2 = 0%; moderate-quality evidence). However, a significant number of participants who received NACT plus hysterectomy also had radiotherapy. There was no difference in the proportion of women with disease progression or recurrence (DFS and PFS) between NACT plus hysterectomy and radiotherapy groups (RR 0.75, 95% CI 0.53 to 1.05; I2 = 20%; moderate-quality evidence). The certainty of the evidence was low or very-low for all other comparisons for all outcomes. None of the trials reported quality of life outcomes.

AUTHORS' CONCLUSIONS

From the available RCTs, we found insufficient evidence that hysterectomy with radiotherapy, with or without chemotherapy, improves the survival of women with LACC who are treated with radiotherapy or CCRT alone. The overall certainty of the evidence was variable across the different outcomes and was universally downgraded due to concerns about risk of bias. The certainty of the evidence for NACT and radical hysterectomy versus radiotherapy alone for survival outcomes was moderate. The same occurred for the comparison involving NACT and hysterectomy compared with CCRT alone. Evidence from other comparisons was generally sparse and of low or very low-certainty. This was mainly based on poor reporting and sparseness of data where results were based on single trials. More trials assessing medical management with and without hysterectomy may test the robustness of the findings of this review as further research is likely to have an important impact on our confidence in the estimate of effect.

Evaluation of early regression index as response predictor in cervical cancer: A retrospective study on T2 and DWI MR images

BACKGROUND AND PURPOSE

Early Regression Index (ERI_TCP) is an image-based parameter based on tumor control probability modelling, that reported interesting results in predicting pathological complete response (pCR) after pre-operative chemoradiotherapy (CRT) in rectal cancer. This study aims to evaluate this parameter for Locally Advanced Cervical Cancer (LACC), considering not only T2-weighted but also diffusion-weighted (DW) Magnetic Resonance (MR) images, comparing it with other image-based parameters such as tumor volumes and apparent coefficient diffusion (ADC).

MATERIALS AND METHODS

A total of 88 patients affected by LACC (FIGO IB2-IVA) and treated with CRT were enrolled. An MRI protocol consisting in two acquisitions (T2-w and DWI) in two times (before treatment and at mid-therapy) was applied. Gross Tumor Volume (GTV) was delineated and ERI_TCP was calculated for both imaging modalities. Surgery was performed for each patient after nCRT: pCR was considered in case of absence of any residual tumor cells. The predictive performance of ERI_TCP, GTV volumes (calculated on T2-w and DW MR images) and ADC parameters were evaluated in terms of area (AUC) under the Receiver Operating Characteristic (ROC) curve considering pCR and two-years survival parameters as clinical outcomes.

RESULTS

ERI_TCP and GTV volumes calculated on DW MR images (ERI_DWI and V_{mid_DWI}) significantly predict pCR (AUC = 0.77 and 0.75 respectively) with results superior to those observed considering T2-w MR images or ADC parameters. Significance was also reported in the prediction of 2-years local control and disease free-survival.

CONCLUSION

This study identified ERI_TCP and V_mid as good predictor of pCR in case of LACC, especially if calculated considering DWI. Using these indicators, it is possible to early identify not responders and modifying the treatment, accordingly.

Neoadjuvant Chemoradiotherapy With Simultaneous Integrated Boost in Locally Advanced Cervical Cancer: Long Term Results of a Single-Center Experience

Aim of this study was to analyze the efficacy and tolerability of simultaneous integrated boost volumetric modulated arc therapy (SIB-VMAT) associated with cisplatin-based chemotherapy in preoperative setting of patients with locally advanced cervical cancer (LACC). From June 2013 to September 2019, we analyzed patients with LACC who had undergone neoadjuvant chemoradiation (CRT). A radiation dose of 39.6 Gy, 1.8 Gy/fraction was delivered to the pelvis plus a radiation dose to the primary tumor delivered with SIB-VMAT strategy for a total of 50.6Gy, 2.3Gy/fraction in 25 fractions. Cisplatin-based chemotherapy was delivered combined with radiotherapy. Radical hysterectomy plus pelvic with or without aortic lymphadenectomy was performed within 7 to 8 weeks from CRT. One hundred forty-eight patients (median age: 49.5 years; FIGO stage IB2: 7, IIA: 8, IIB: 106, IIIA: 5; IIIB: 16; IVA: 5, IVB: 1; N0: 56, N1: 92) were analyzed. The treatment was well tolerated with good compliance: no grade 3/4 gastrointestinal or genitourinary toxicity was reported; grade 3 neutropenia was described in five cases. Pathological complete response (pCR) was documented in 68 cases (46%) and 32 patients (21.6%) had microscopic residual disease. Pathological nodal involvement was observed in 23 patients (15.5%). At median follow-up of 59 months (range: 27-100), the 3-year local control was 78.5%, whereas the 3-year metastasis-free survival was 70.5%. The 3-year overall survival rate was 89.0%. Neoadjuvant CRT with SIB-VMAT followed by radical surgery results in a high rate of pathologically assessed complete response and a very encouraging local control rate, with acceptable toxicity.

Clinical Impact of Pathologic Residual Tumor in Locally Advanced Cervical Cancer Patients Managed by Chemoradiotherapy Followed by Radical Surgery: A Large, Multicenter, Retrospective Study

BACKGROUND

Exclusive chemoradiation (E-CT/RT) represents the standard of treatment for locally advanced cervical cancer (LACC). Chemoradiation (CT/RT) followed by radical surgery (RS) may play a role for patients with a suboptimal response to CT/RT or in low-income countries with limited access to radiotherapy. Histologic assessment of residual tumor after CT/RT and RS allows accurate definition of prognostic categories.

METHODS

Data on patients with FIGO stages 1B2 to 4A cervical cancer managed by CT/RT and RS from June 1996 to March 2020 were retrospectively analyzed. Pathologic response on the cervix was defined as complete (pCR), microscopic (persistent tumor foci ≤ 3 mm) (pmicroR), or macroscopic (persistent tumor foci > 3 mm) (pmacroR). Lymph node (LN) residual tumor was classified as absent or present.

RESULTS

The 701 patients in this study underwent CT/RT and RS. Of the 701 patients, 293 (41.8%) had pCR, 188 (26.8%) had pmicroR, and 220 (31.4%) had pMacroR. Residual tumor was found in the pelvic lymph nodes of 66 (9.4%) patients and the aortic lymph nodes of 29 (4.1%) patients. The 5-year DFS and OS were respectively 86.6% and 92.5% in the pCR cases, 80.3% and 89.1% in the pmicroR cases, and 56.2% and 68.8% in the pmacroR cases. Among the patients with lymph node residual tumor, the 5-year DFS and OS were respectively 16.7% and 40% in the pCR cases, 35.4% and 53.3% in the pmicroR cases, and 31.7% and 31.1% in the pmacroR cases. Cervical residual tumor,, positive pelvic LNs, and positive aortic LNs were associated with worse DFS and OS in both the uni- and multivariate analyses.

CONCLUSIONS

Persistence of pathologic residual tumor on the cervix and LNs after CT/RT are reliable predictors of survival for LACC patients undergoing CT/RT and adjuvant surgery.

Neoadjuvant chemotherapy with paclitaxel plus cisplatin before radical surgery for locally advanced cervical cancer during pregnancy: A case series and literature review

RATIONALE

Despite the development of human papillomavirus vaccines and significant improvement in cervical cancer screening over the past few years, cervical cancer remains the fourth most common cancer in women of childbearing age after breast cancer, melanoma, and thyroid cancer.

PATIENT CONCERNS

In this case report, the patients are all cervical cancer with stage IB2 and IB3 during pregnancy, the management constitutes a major medical challenge related to the impact of treatment on both maternal and fetal outcomes. Neoadjuvant chemotherapy (NACT) is an innovative option for cervical cancer patients with stage IB2 and IB3 before cesarean delivery and radical hysterectomy, and many chemotherapeutic agents are available, cisplatin plus paclitaxel yielded good maternal and fetal outcomes to the authors' knowledge.

DIAGNOSES

Masses were discovered in the cervix of 4 pregnant women with a history of vaginal bleeding. Biopsy examination of the masses revealed cervical carcinoma, which was staged in accordance with the International Federation of Gynecology and Obstetrics (i.e., FIGO) system.

INTERVENTIONS

The patients were treated with paclitaxel plus cisplatin, followed by cesarean delivery and radical hysterectomy.

OUTCOMES

The 4 patients were treated successfully, with no recurrence during follow-up periods of 14 to 56 months, and all of the children were doing well with no anomalies.

LESSONS

Although further data are required, in pregnant women with invasive cervical cancer, NACT with cisplatin plus paclitaxel followed by cesarean delivery and radical hysterectomy was a practical treatment option.

Optimal treatment in locally advanced cervical cancer

Introduction: Locally advanced cervical cancer (LACC) (International Federation of Gynecology and Obstetrics (FIGO) 2009/2018 - stages IB2-IVA/IB3-IVA, respectively) is treated using a multimodal approach that includes chemoradiotherapy followed by brachytherapy.Areas covered: This review provides an overview of the progress made over the past decade in the treatment of LACC. Prognostic factors, FIGO classification and the role of imaging staging will be discussed. Efficacy of external-beam radiotherapy, brachytherapy and chemotherapy will be detailed. Indications for para-aortic staging lymphadenectomy and adjuvant hysterectomy, as well as follow-up and special population, will be covered.Expert opinion: The initial workup is one of the most crucial steps in the optimal care of patients, which should be realized by a multidisciplinary expert team. With the implementation of modern conformal radiotherapy techniques, the local control rate has been optimized. Nevertheless, 40% of patients experience recurrence with distant metastasis and a dismal prognosis. Currently, a clear benefit of neo- and adjuvant chemotherapy has not been established. The future likely involves (1) improved selection of patients for whom treatment intensification is justified, (2) a combination of new drugs with chemoradiation that are currently being tested in trials, and (3) the development of tailored treatment based on molecular characteristics.

Salvage surgery for patients with residual disease after chemoradiation therapy for locally advanced cervical cancer: A systematic review on indication, complications, and survival

Introduction

Standard treatment for locally advanced cervical cancer is chemoradiation therapy. Treatment with chemoradiation therapy harbors a risk of local residual disease, which can be curatively treated with salvage surgery, but the risk of complications following surgical procedures in radiated tissue is not negligible. The presence of residual disease can be radiologically and/or histologically diagnosed. The objective of this study is to describe studies that report on salvage surgery for patients with locally advanced cervical cancer after primary treatment with chemoradiation therapy. Therefore, we assessed the method of determining the presence of residual disease, the risk of complications, and the survival rate after salvage surgery.

Material and methods

PubMed, EMBASE, and the Cochrane database were searched from inception up to 6 March 2020. Titles and abstracts were independently assessed by two researchers. Studies were eligible for inclusion when patients had locally advanced cervical cancer with radiologically suspected or histologically confirmed residual disease after chemoradiation therapy, diagnosed with a CT, MRI, or PET‐CT scan, or biopsy. Information on complications after salvage surgery and survival outcomes had to be reported. Methodological quality of the articles was independently assessed by two researchers with the Newcastle‐Ottawa scale.

Results

Of the 2963 screened articles, six studies were included, representing 220 women. A total of 175 patients were treated with salvage surgery, of whom 27%‐100% had residual disease on the surgery specimen. Of the 161 patients treated with salvage surgery based on positive biopsy results, 72%‐100% showed residual disease on the surgery specimen. Of the 44 patients treated with salvage surgery based on suspected residual disease on radiology, 27%‐48% showed residual disease on the salvage surgery specimen. A total of 105 complications were registered in 175 patients treated with salvage surgery. The overall survival rate after salvage surgery was 69% (mean follow‐up period of 24.9 months).

Conclusions

It is necessary to confirm residual disease by biopsy before performing salvage surgery in patients with locally advanced cervical cancer primarily treated with chemoradiation therapy. Salvage surgery only based on radiologically suspected residual disease should be avoided to prevent unnecessary surgery and complications.

Propensity score-matched analysis of systemic chemotherapy versus salvage hysterectomy for persistent cervical cancer after definitive radiotherapy/concurrent chemoradiotherapy

BACKGROUND

The aim of the current study was to evaluate oncologic outcomes of patients who were treated with salvage hysterectomy (HT), compared to systemic chemotherapy (CT) for persistent cervical cancer after definitive radiotherapy (RT)/ concurrent chemoradiotherapy (CCRT).

METHODS

Patients with persistent cervical cancer treated with definitive RT/CCRT at 35 institutions from 2005 to 2014 were reviewed retrospectively (n = 317). Those who underwent a HT for persistent cervical cancer after definitive RT/CCRT were matched with propensity scores for patients who underwent systemic CT. Oncologic outcomes between the two groups using a propensity score matched-cohort analysis were compared.

RESULTS

A total of 142 patients with persistent cervical cancer after definitive RT/CCRT were included after matching (HT: 71, systemic CT: 71). All background factors between HT and CT groups were well balanced. Median overall survival was 3.8 and 1.5 years in the HT and CT groups, respectively (p = 0.00193, hazards ratio [HR] 0.41, 95% confidence interval [CI] 0.23-0.73), Increasing residual tumor size was significantly associated with a high incomplete resection rate (p = 0.016, Odds Ratio 1.11, 95%CI 1.02-1.22). Severe late adverse events occurred in 7 patients (9.9%) in the HT cohort.

CONCLUSION

The current study demonstrated that, when compared to systemic CT, the adoption of salvage HT for patients with persistent cervical cancer after definitive RT/CCRT reduced mortality rate by about 60%. This indicates that salvage HT could be curative treatment for those patients. Further prospective clinical trials with regard to salvage HT after RT/CCRT are warranted.

Evaluation of an Early Regression Index (ERITCP) as Predictor of Pathological Complete Response in Cervical Cancer: A Pilot-Study

Background: Recent studies have highlighted the potentialities of a radiobiological parameter, the early regression index (ERITCP), in the treatment response prediction for rectal cancer patients treated with chemoradiotherapy followed by surgery. The aim of this study is to evaluate the performance of this parameter in predicting pathological complete response (pCR) in the context of low field MR guided radiotherapy (MRgRT) for cervical cancer (CC). Methods: A total of 16 patients affected by CC were enrolled. All patients underwent a MRgRT treatment, with prescription of 50.6 Gy in 22 fractions. A daily MR acquisition was performed at simulation and on each treatment fraction. Gross tumor volume (GTV) was delineated on the MR images acquired at the following biological effective dose (BED) levels: 14, 28, 42, 54 and 62 Gy. The ERITCP was calculated at the different BED levels and its predictive performance was quantified in terms of receiver operating characteristic (ROC) curve. Results: pCR was observed in 11/16 cases. The highest discriminative power of ERITCP was reported when a BED value of 28 Gy is reached, obtaining an area under curve (AUC) of 0.84. Conclusion: This study confirmed ERITCP as a promising response biomarker also for CC, although further studies with larger cohort of patients are recommended.

Minimally Invasive Approaches in Locally Advanced Cervical Cancer Patients Undergoing Radical Surgery After Chemoradiotherapy: A Propensity Score Analysis

Purpose

Chemoradiation (CT/RT) followed by radical surgery (RS) may play a role in locally advanced cervical cancer (LACC) patients with suboptimal response to CT/RT or in low-income countries with limited access to radiotherapy. Our aim is to evaluate oncological and surgical outcomes of minimally invasive radical surgery (MI-RS) compared with open radical surgery (O-RS).

Patients and Methods

Data for stage IB2–IVA cervical cancer patients managed by CT/RT and RS were retrospectively analyzed.

Results

Beginning with 686 patients, propensity score matching resulted in 462 cases (231 per group), balanced for FIGO stage, lymph node status, histotype, tumor grade, and clinical response to CT/RT. The 5-year disease-free survival (DFS) was 73.7% in the O-RS patients and 73.0% in the MI-RS patients (HR 1.034, 95% CI 0.708–1.512, p = 0.861). The 5-year locoregional recurrence rate was 12.5% (O-RS) versus 15.2% (MI-RS) (HR 1.174, 95% CI 0.656–2.104, p = 0.588). The 5-year disease-specific survival (DSS) was 80.4% in O-RS patients and 85.3% in the MI-RS group (HR 0.731, 95% CI 0.438–1.220, p = 0.228). Estimated blood loss was lower in the MI-RS group (p < 0.001), as was length of hospital stay (p < 0.001). Early postoperative complications occurred in 77 patients (33.3%) in the O-RS group versus 88 patients (38.1%) in the MI-RS group (p = 0.331). Fifty-six (24.2%) patients experienced late postoperative complications in the O-RS group, versus 61 patients (26.4%) in the MI-RS group (p = 0.668).

Conclusion

MI-RS and O-RS are associated with similar rates of recurrence and death in LACC patients managed by surgery after CT/RT. No difference in early or late complications was reported.

Is a Vaginectomy Enough or is a Pelvic Exenteration Always Required for Surgical Treatment of Recurrent Cervical Cancer? A Propensity-Matched Study

PURPOSE

Reporting the perioperative and survival outcomes of vaginectomy with respect to a matched series of pelvic exenteration (PE) in women with isolated recurrent cervical cancer.

METHODS

The records of vaginal recurrent cervical cancer patients admitted at Fondazione Policlinico "Agostino Gemelli" IRCCS in Rome from January 2010 to June 2019 were retrospectively analyzed. A propensity-matched score analysis was performed by age, clinical stage, disease-free interval, and R0 resection. Postsurgical complications and survival rates were evaluated.

RESULTS

Fifteen women underwent vaginectomy, and 30 patients were submitted to PE. No statistical differences were observed between the two groups at baseline characteristics. The vaginectomy procedures were successfully performed in all women, and no case required conversion to PE. Moreover, a higher rate of major postoperative complications after PE with respect to vaginectomy (p = 0.027) was recorded. Among them, three women required reoperation within 30 postoperative days, and four experienced two or more complications. Twenty-five (55.6%) women experienced recurrence: 8 of 25 (32.0%) in the vaginectomy group, and 17 of 25 (68%) in the PE group, with a median progression-free survival of 20 months and 13 months, respectively (p = 0.169). In total, 5 of 15 (33.3%) died of disease in the vaginectomy group and 13/30 (43.3%) in the PE group, with a median overall survival of 39 and 18 months for vaginectomy and PE, respectively (p = 0.161).

CONCLUSIONS

The vaginectomy seems to allow for salvage treatment, such as radiotherapy and/or PE, but with a minimal impact on the quality of life in appropriately selected women with local recurrent cervical cancer.

Perioperative Complications and Safety Evaluation of Robot-Assisted Radical Hysterectomy of Cervical Cancer After Neoadjuvant Chemotherapy

Purpose

To evaluate the perioperative complications of patients with cervical cancer who are treated with robot-assisted radical hysterectomy (RRH) and to further evaluate the safety of patients undergoing NACT.

Methods

A total of 805 consecutive cervical cancer patients undergoing RRH were involved in this report. Their clinical characteristics were retrieved from hospital medical records. Perioperative complications were subdivided into intraoperative and postoperative complications, which were graded according to the Clavien-Dindo classification (CDC), and the complications of grade III and above were defined as severe complications. Furthermore, the two-level logistic regression model was used to estimate the risk factors of perioperative and severe complications and to further confirm the relationship between NACT and perioperative and severe complications.

Results

The perioperative complication rate and severe complications were 45.09% and 7.83%, respectively. Poorly differentiated tumor and NACT were identified as independent risk factors for perioperative complications by multifactor analysis. Furthermore, we concentrated on the relations between NACT and complications. The risk of perioperative complications of the group with NACT (OR = 11.08, 95% CI: 5.70-21.54) was significantly higher than the group without NACT, especially in postoperative complications (OR=17.65, 95% CI: 8.63-36.08), even after adjusting confounding factors. However, there was no statistically significant difference in terms of severe complications (OR=1.68, 95% CI: 0.64-4.41) and intraoperative complications (OR=0.51, 95% CI: 0.18-1.41). Moreover, as the times of NACT increase, the impact on perioperative complications is more pronounced. A similar trend was observed in postoperative complications, while this statistical difference was still not observed in intraoperative and severe complications.

Conclusion

This result demonstrates the feasibility and safety of RRH of cervical carcinoma after NACT in generally, since it only causes mild complications, not severe complications.

Operation for locally advanced cervical cancer after concurrent chemoradiotherapy

OBJECTIVE

This paper aimed to discuss the scope of operation and clinical effects for locally advanced cervical cancer (LACC) after concurrent chemoradiotherapy (CCRT).

METHODS

We retrospectively reviewed the records of 444 patients with stages IB2-IIB cervical cancer who were divided into two groups whether or not they received CCRT before radical operation in our institute from January 2013 to December 2016. Patients' characteristics, treatments, and outcomes were analyzed.

RESULTS

The total efficiency (CR + PR) of the CCRT + operation group was 96.2%. Specifically, the CR rate was 9.1%, and the PR rate was 87.1%. The positive rates of cervical deep interstitial infiltration, lymphatic metastasis, and lymphangial infiltration of the operation group were significantly higher than those of the CCRT + operation group (P < 0.05). A total of 24 and 162 patients in the CCRT + operation group and the operation group, respectively, received adjuvant therapy (P < 0.05). The incidence rate of edema of the lower extremity, radiation enteritis, and radiocystitis after postoperative adjuvant radiotherapy in the operation group was significantly higher than that of the CCRT + operation group (P < 0.05). The 5-year survival rates and 5-year progression-free survival (PFS) rates of the CCRT + operation and operation groups were 79.3% versus 64.0% and 68.9% versus 45.2%, respectively (P < 0.05).

CONCLUSIONS

Comprehensive treatment that combines CCRT and radical operation to LACC achieves satisfying clinical effects without increasing the occurrence rate of intraoperative and postoperative complications. Moreover, such treatment can improve the 5-year PFS rate and OS rate.

Surgical outcomes of segmental ureteral resection with ureteroneocystostomy after major gynecologic surgery

INTRODUCTION

Describing the surgical and oncological outcome of bladder-preserving ureter reconstruction (BPUR) with segmental ureteral resection after major gynecologic surgery.

MATHERIALS AND METHODS

Patients with BPUR admitted at a single institution between March 2012 and July 2018 were retrospectively analyzed. Surgical and oncological data were assessed.

RESULTS

Forty-six women with gynecologic tumors involving the ureter were treated with BPUR. R0 resection was achieved in 40/46 patients (86.9%), while pathologic margins were microscopically positive in 6 women (13.1%). Overall, 12 women (26.0%) received radiotherapy before surgery: among them, 8 patients received neoadjuvant chemoradiotherapy. Twenty-six women underwent BPUR during primary surgery, whereas 20 (43.4%) required BPUR upon recurrence. Twenty-six patients (56.2%) were found to have hydronephrosis at pre-operative workup. The psoas bladder hitch was the most common procedure performed for urinary reconstruction (63%) with respect to direct reimplantation (37%). Fourteen patients (14/46 = 30.4%) experienced urological complications. Urinary leakage occurred in 9 patients (19.5%), specifically: 5 uretero-vaginal fistula, 3 uroperitoneum, 1 uretero-enteral fistula. There were 3 cases (6.5%) of hydronephrosis at the side of ureteroneocystostomy and 2 cases (4.3%) of unilateral renal impairment requiring nephrectomy. At multivariate analysis only pre-operative radiotherapy (p = 0.047) and a history of pelvic irradiation (p = 0.025) were independently associated with an increased risk of developing severe urinary complications.

CONCLUSIONS

BPUR is feasible in gynecologic cancer with invasion of the urinary tract. However, since a slight increase of post-operative urological complications was observed in the previously irradiated fields, a personalized surgical planning is recommended for these women in the next future.

Low Tesla magnetic resonance guided radiotherapy for locally advanced cervical cancer: first clinical experience

OBJECTIVE

Magnetic resonance-guided radiotherapy (MRgRT) represents an innovative approach for personalized radiotherapy treatments and its applications are being explored in various anatomical sites to fully understand its potential advantages. This study describes the first clinical experience of MRgRT application in patients with locally advanced cervical cancer (LACC) undergoing neoadjuvant chemoradiotherapy. The feasibility of the technique is evaluated and its toxicity profile and clinical outcomes are reported.

METHODS

Patients with LACC (International Federation of Gynecology and Obstetrics stage IIA-IVA) undergoing neoadjuvant chemoradiotherapy (CRT) on a 0.35T Tri-60-Co hybrid unit (ViewRay) were retrospectively compared with randomly selected patients treated with a standard linear accelerator. Total prescribed dose was 50.6 Gy (2.3 Gy/fraction) to planning target volume 1 (PTV1) and 39.6 Gy (1.8 Gy/fraction) to PTV2, delivered using a simultaneous integrated boost. Surgery was performed 8 weeks after the end of CRT. The effect of magnetic resonance guidance on replanning approaches, treatment-related toxicities, and pathologic response were assessed for each patient. Patient outcomes were noted and dosimetric comparisons performed between the 2 arms.

RESULTS

Nine patients with LACC treated from May 2018 to November 2018 were retrospectively enrolled and their records compared with the records of an equivalent cohort of randomly selected patients. Five replanning cases were performed in the MRgRT group and 0 in the linear accelerator group. Acute G1-G2 gastrointestinal toxicities were observed in 33.3% of MRgRT patients and in 55.5% of linear accelerator patients; acute G1-G2 genitourinary toxicities in 22.2% and 33.3%, respectively. No G3 toxicity was found except for neutropenia in 2 patients. No differences were observed in pathologic response between the 2 groups.

CONCLUSIONS

Despite the retrospective nature of the observations and the low number of enrolled patients, the application of MRgRT in LACC appears to be safe and feasible with a favorable toxicity profile and response rates comparable to gold standard, supporting the setup of larger prospective studies to investigate the potentialities of this new technology.

Lessons from radiochemotherapy and modern image-guided adaptive brachytherapy followed by hysterectomy

PURPOSE

To analyze the clinical outcomes and the safety of radiochemotherapy (RCT) and image-guided adaptive brachytherapy (IGABT) and to evaluate the impact of hysterectomy (HT) as completion of treatment for cervical cancer.

METHODS AND MATERIALS

145 patients with locally advanced cervical cancer were treated at our institution. Patients underwent RCT and IGABT, then hysterectomy (HT) as completion of treatment was performed, with the exception of patients with surgical contraindications, para aortic metastatic disease or patients who refused surgery. Clinical outcomes and morbidity were retrospectively reviewed in both groups. Local relapse free survival (LRFS), pelvic relapse free survival (PRFS) and overall survival (OS) were analyzed.

RESULTS

Completion HT was performed in 90 (62.1%) patients. Complete histological response and microscopic disease were found in 77 patients (85.6%). Local relapse was observed in 14 patients (9.6%) without differences between completion HT group and the definitive RCT and IGABT group (Odds Ratio OR = 1.73 [0.57-5.23], p = 0.33). The estimated 3-year LRFS and PRFS for the entire population were respectively 90% [84%-94%] and 93% [87%-96%], with no significant differences between them (respectively Hazard Ratio HR = 0.57 [0.20-1.64], p = 0.30 and HR = 0.37 [0.10-1.31], p = 0.12). The estimated 3-year OS rate for the whole population was 84% [75%-91%] with no significant differences between groups (HR = 0.81 [0.32-2.06], p = 0.65). Regarding morbidity, grade ≥ 2 vaginal toxicity was more frequent in the definitive RCT and IGABT group (43.6% vs 26.7%, p = 0.04). All grade 4 toxicity events were reported in the completion HT group.

CONCLUSIONS

Due to high severe toxicity, RCT and IGABT with dose escalation followed by completion hysterectomy don't seem compatible. No benefit and increased severe late morbidity were observed. Combined intracavitary/interstitial technique is mandatory in large target volume at brachytherapy.

Completion hysterectomy after chemoradiotherapy for locally advanced adeno-type cervical carcinoma: updated survival outcomes and experience in post radiation surgery

OBJECTIVE

To compare patient survival outcomes between completion hysterectomy and conventional surveillance in locally advanced adenocarcinoma of the cervix after concurrent chemoradiotherapy (CCRT).

METHODS

Patients with adenocarcinoma of the cervix after CCRT were identified in a tertiary academic center database from 2004 to 2018. Patients received completion hysterectomy or surveillance after CCRT. We compared the progression-free survival (PFS) and overall survival (OS) between the patients with or without adjuvant hysterectomy. Surgery features, operative complications, and pathologic characteristics were documented. Patient outcomes were also analyzed according to clinicopathologic factors.

RESULTS

A total of 78 patients were assigned to completion surgery and 97 to surveillance after CCRT. The PFS was better in the surgery group compared to the CCRT only group, at 3 years the PFS rates were 68.1% and 45.2%, respectively (hazard ratio [HR]=0.46; 95% confidence interval [CI]=0.282-0.749; p=0.002). Adjuvant surgery was also associated with a higher rate of OS (HR=0.361; 95% CI=0.189-0.689; p=0.002), at 3 years, 87.9% and 67%, respectively. Tumor stage, size, lymph-vascular space invasion (LVSI), lymphadenopathy were associated with PFS but not with OS. Hysterectomy specimens revealed 64.1% (50/78) of the patients had pathologic residual tumor. Patients age less than 60, tumor size over 4 cm, stage IIB and persistent residual disease after CCRT were most likely to benefit from hysterectomy. Hysterectomy was associated with a lower rate of locoregional recurrence but did not reach statistical significance (5.13% vs. 13.5%, p=0.067).

CONCLUSION

Completion hysterectomy after CCRT was associated with better survival outcome compared with the current standard of care.

The role of 18F-FDG-PET/CT in predicting the histopathological response in locally advanced cervical carcinoma treated by chemo-radiotherapy followed by radical surgery: a prospective study

PURPOSE

This prospective study aimed to evaluate whether ¹⁸F-FDG-PET/CT performed before, during and after neoadjuvant chemo-radiotherapy (CRT) could predict histopathological response in patients with locally advanced cervical cancer (LACC) treated with CRT followed by radical surgery.

METHODS

Between October 2010 and June 2014, 88 patients with LACC were enrolled. For each patient, three ¹⁸F-FDG-PET/CT scans (baseline, early and final) were acquired and evaluated by qualitative and quantitative analysis. Maximum standardized uptake value (SUV_max), SUV_mean, metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were measured as absolute values and their percentage variation (delta) (early vs. baseline and final vs. baseline). The role of ¹⁸F-FDG-PET/CT in predicting lymph node (LN) residual disease was evaluated by qualitative analysis only. Histopathology was the reference standard.

RESULTS

At histopathology, 40 patients had complete response (CR, pR0), 48 had partial response (PR: 21 microscopic [pR1] and 27 macroscopic [pR2]). At baseline, SUV_max and SUV_mean were significantly higher in pR0 than in pR1-pR2 patients. At early evaluation, MTV and TLG were significantly higher in pR1-pR2 than in pR0 patients. At final evaluation, SUV_max, SUV_mean and TLG were significantly higher in pR1-pR2 than in pR0 patients. Delta SUV parameters and delta TLG were significantly lower in PR group both during and after CRT. Delta MTV was significantly lower in patients with PR in the early phase only. In receiver operating characteristic (ROC) curve analysis, baseline SUV_mean, early delta TLG, and final delta SUV_max better discriminated PR, providing 83.3%, 67.6% and 85% positive predictive value (PPV) and 60.3%, 90% and 70.8% negative predictive value (NPV), respectively. For LN assessment, high NPV was observed at early and final ¹⁸F-FDG-PET/CT (93.5% and 92.3%, respectively).

CONCLUSION

In LACC patients treated with CRT followed by surgery, early variations in metabolic parameters effectively discriminate histopathological PR of the primary tumor, suggesting the potential role of ¹⁸F-FDG-PET/CT in early personalized treatment. The high NPV of early and final PET/CT could enable "tailored surgery" by avoiding lymphadenectomy in selected patients.

Surgery of primary sites for stage IVB cervical cancer patients receiving chemoradiotherapy: a population-based study

OBJECTIVE

The purpose of this study was to analyze the impact of surgery of primary sites on stage IVB cervical cancer patients from a population-based database, the Surveillance, Epidemiology and End Results (SEER).

METHODS

Propensity score matching was performed to minimize heterogeneity in patient between with-surgery group and without-surgery group. Clinicopathological characteristics were compared using the χ² or Fisher's exact test. Survival analysis included the Kaplan-Meier method, log-rank test, and Cox proportional hazards model.

RESULTS

Between 2010-2015, a total of 1,139 International Federation of Gynecology and Obstetrics (FIGO) stage IVB cervical cancer patients receiving chemoradiotherapy (CRT) were included in this retrospective study. Within post-matching cohort, the median duration of overall survival (OS) in stage IVB cervical cancer patients receiving CRT was 22 months. The overall 5-year survival rate was 25.7%. The increasing American Joint Committee on Cancer T stage (T1 vs. T2, p=0.033, hazard ratio [HR]=1.79, 95% confidence interval [CI]=1.05-3.05; T1 vs. T3, p=0.003, HR=2.20, 95% CI=1.31-3.67; T1 vs. T4, p=0.037, HR=2.75, 95% CI=1.06-7.12) and visceral metastasis (with vs. without, p=0.038, HR=1.60, 95% CI=1.03-2.49) was reported as independent risk factors of OS. Surgery of primary sites combined with CRT tended to prolong the survival of stage IVB cervical cancer patients (p<0.001, HR=0.36, 95% CI=0.21-0.61) compared with CRT, especially for patients without visceral metastasis (p=0.005, HR=0.31, 95% CI=0.14-0.70).

CONCLUSIONS

In conclusion, patients with stage IVB cervical cancer may achieve their best outcomes through CRT combined with surgery of primary sites. However, it deserves large scale prospective clinical trials to confirm.

Radical Surgery in Advanced Cervical Cancer Patients Receiving Bevacizumab-Containing Chemotherapy: A "Real Life Experience"

BACKGROUND

Platinum-based chemotherapy plus bevacizumab is the new standard of care in stage IVB cervical cancer (CC) patients. In this new scenario, radical surgery could be offered in selected cases with an optimal clinical response. Potential surgical complications related to previous bevacizumab treatment have never been described before in this type of setting.

METHODS

This is a single-institutional retrospective study on women with CC who received radical pelvic surgery after platinum-based chemotherapy (platinum-taxol) plus bevacizumab.

RESULTS

Between April 2016 and September 2017, 15 patients with CC underwent radical surgery after bevacizumab-containing chemotherapy (platinum-taxol) at the Division of Gynecologic Oncology, Catholic University of the Sacred Heart in Rome, Italy.All patients received at least 3 cycles of treatment. Fourteen (93.4%) patients underwent radical hysterectomy, whereas 1 patient received pelvic anterior exenteration. Median operating time was 290 minutes (range, 220-400), and estimated blood loss was 250 mL (range, 50-1500). Median time of hospitalization was 5 days (range, 2-21). Pathological response in the cervix was complete in 3 cases and microscopic in 1 patient (26.7%). Intraoperative complications occurred in 3 cases: 2 vascular injuries and 1 ureteral injury. Three patients (20.0% of the whole series) experienced grade 3 complications.At last follow-up (median time, 9 months), the median overall survival is 13 months (range, 6-31): 7 (46.7%) women were free of disease, 8 (53.3%) patients progressed, and 3 of them died of disease.

CONCLUSIONS

Radical surgery can be performed in women with CC previously treated with a bevacizumab-containing regimen.

Health-related quality of life in locally advanced cervical cancer patients treated with neoadjuvant therapy followed by radical surgery: A single-institutional retrospective study from a prospective database

OBJECTIVE

To evaluate the health-related quality of life (HRQOL) in locally advanced cervical cancer (LACC) patients treated with neoadjuvant concurrent chemoradiation (CCRT) or radiation (RT) alone followed by radical surgery (RS).

METHODS

In a single-center retrospective study from a prospective database, 275 FIGO Stage IB2-IIIB patients who underwent CCRT/RT + RS were included. HRQOL was prospectively assessed by EORTC QLQ-C30 and EORTC QLQ-CX24 prior to any treatment (baseline) and 6 months after surgery, respectively.

RESULTS

A statistically significant and clinically relevant improvement in physical functioning (P < 0.001) and role functioning (P = 0.002, P = 0.031) was observed in patients receiving either CCRT+RS or RT + RS at follow-up. In addition, quality of life (QoL), physical functioning, and social functioning were better in the RT + RS group than the CCRT+RS group after treatment (P = 0.028, P = 0.010, P = 0.014). Symptom scores of fatigue decreased in both groups over time (P < 0.001, P = 0.004) while insomnia decreased only in the RT + RS group (P = 0.042). Worsened menopausal symptoms were documented in both groups at follow-up (P = 0.001, P = 0.047), while lymphedema was deteriorated only in patients receiving CCRT + RS (P < 0.001). Sexuality scores did not differ between groups or over time with the exception of sexual worry, which was deteriorated in patients receiving RT + RS (P = 0.042).

CONCLUSIONS

QLQ-C30 functioning and tumor-related symptoms scores improved while lymphedema and menopausal symptoms worsened 6 months after neoadjuvant CCRT or RT alone followed by RS in LACC patients. Patients treated with RT + RS had a generally better HRQOL compared with those receiving CCRT+RS, though further validation with prospective randomized clinical trials is warranted.

Efficacy of neoadjuvant platinum-based chemotherapy during the second and third trimester of pregnancy in women with cervical cancer: an updated systematic review and meta-analysis

PURPOSE

To evaluate the efficacy and safety of neoadjuvant platinum-based chemotherapy during pregnancy in women with cervical cancer.

METHODS

The PubMed, Embase, and Cochrane Library databases were fully searched to find eligible studies regarding platinum use during pregnancy in women with cervical cancer from January 1980 to September 2018. Data were extracted from the selected studies independently by two authors. Descriptive statistics were calculated for categorical data (frequency and percentage) and numeration data (mean and SD for normally distributed data and median and range for abnormally distributed data). Survival analyses were performed using Kaplan-Meier survival curves and log-rank tests to estimate overall survival and progression-free survival for all patients.

RESULTS

A total of 39 studies including 88 cervical cancer patients with platinum administration during pregnancy were selected in this meta-analysis, and 64 women provided International Federation of Gynecology and Obstetrics stage information. Among the latter, 56 of 64 (87.5%) were diagnosed with early stages (I and IIA) and the remaining 8 of 64 (12.5%) had advanced stages (IIB, III, and IV). In relation to cisplatin, 86 pregnant women were identified, whereas only 2 pregnant women with carboplatin application were retrieved. Overall, 88 newborns were delivered from 84 pregnancies, including two sets of twins and one set of triplets, among which 71 neonates (71 of 88, 80.7%) were completely healthy at birth. All children were healthy at the end of follow-up (median 17 months, range 0-149.5 months), except one who was diagnosed with retroperitoneal embryonal rhabdomyosarcoma at 5 years old and one who had acute myeloid leukemia at 22 months of age. At the end of follow-up (range 4.75-156 months), 16 of 81 (19.8%) patients were diagnosed with recurrence of cervical cancer, and 11 (90%) of those died because of cancer relapse. Neither median overall survival nor median progression-free survival were reached.

CONCLUSION

Our results demonstrated that neoadjuvant platinum-based chemotherapy could be a favorable choice for the management of patients with cervical cancer during the second and third trimesters. To reduce the side effects of chemotherapy, cisplatin might be good to use as monotherapy in these patients.

A prospective study on neoadjuvant chemoradiotherapy plus anti-EGFR monoclonal antibody followed by surgery for locally advanced cervical cancer

Background

To investigate the efficacy and safety of neoadjuvant chemoradiotherapy plus anti-epidermal growth factor receptor monoclonal antibody followed by surgery for locally advanced cervical cancer (LACC).

Patients and methods

Patients with histologically proven LACC were enrolled into this prospective study. All patients received intensity-modulated radiation therapy with conventional fractionation. Weekly cisplatin or nedaplatin was administered concurrently with intensity-modulated radiation therapy. Nimotuzumab, a humanized anti-epidermal growth factor receptor monoclonal antibody, was given at a dose of 200 mg per week for 6 cycles. Approximately 1 month after the completion of neoadjuvant treatment, the patients were assessed for clinical tumor response and operability based on MRI and gynecological examination. For those who were considered to be candidates for surgery, radical hysterectomy, and pelvic lymph node dissection were performed 5–6 weeks after the completion of neoadjuvant therapy.

Results

Twenty-eight patients were enrolled. Clinical complete response and partial response were found in 8 (28.5%) and 20 (71.5%) patients, respectively. Four patients were not eligible for surgery and 2 patients refused surgery although they were assessed as surgical candidates. They were not included in this analysis. Radical hysterectomy and pelvic lymph node dissection were performed for the remaining 22 patients. Among them, 8 (36.4%) had complete pathology response, 9 (40.9%) presented with persistent atypical cells or cervical intraepithelial neoplasia, and 5 (22.7%) presented with macroscopic and/or microscopic residual disease, according to the pathological evaluation. Median follow-up time was 22 months (range, 5–39 months). The 2-year locoregional control rate, progression-free survival rate, distant metastasis-free survival rate, and overall survival rate were 95.0%, 85.2%, 84.0%, and 90.0%, respectively. Acute toxicities were mild in general and easily manageable. Chronic toxicities were mainly limited to grade 1. No severe late toxicities were observed.

Conclusion

Concurrent chemoradiotherapy plus nimotuzumab followed by surgery is highly effective and safe in LACC. Further studies are warranted to confirm the findings.

Individualized pelvic lymphadenectomy should follow neoadjuvant concurrent chemoradiotherapy for locally advanced cervical cancer

To study the outcomes following concurrent chemoradiotherapy (CCRT) and subsequent radical surgery for locally advanced cervical cancer (LACC), analyze the relationship between imaging-diagnosed and postoperative-diagnosed lymph node (LN) involvement, and identify patients who would benefit from individualized pelvic lymphadenectomy.We retrospectively reviewed records of 410 patients who underwent CCRT followed by radical surgery for International Federation of Gynecology and Obstetrics Stage Ib2-IIIb disease. Correlations of LN size on imaging before CCRT with pathological responses after CCRT, overall survival (OS), distant metastasis-free survival (DMFS), and complications were analyzed.During a median follow-up of 51.3 months, the respective 5-year OS and DMFS were 86.7% and 88.6%, respectively. Pathological primary tumor type, LN size on imaging before CCRT, and pathologic response after CCRT were independent prognostic factors for OS. Patients with a LN ≥0.8 cm had a significantly higher residual carcinoma rate versus those with LN <0.8 cm (33% vs 22.6%, P = .032). Postoperative pathological positive LN frequencies differed significantly by LN size on imaging (LN <0.8 cm vs LN ≥0.8 cm, 3% vs 19.3%, P < .0001). Grade 1-3 lower extremity edema occurred in 23.9% of cases; no grade 3-4 gastrointestinal and genitourinary toxicities were observed.CCRT followed by radical surgery for LACC yielded encouraging outcomes without unacceptable complications. Additionally, patients with a LN <0.8 cm on imaging before CCRT had a very low risk of postoperative pathological positive LN identification. Individualized pelvic lymphadenectomy (e.g., omitting or limiting the extent of LN dissection) might be an alternative option for some patients with a low risk of LN metastasis.

Impact of adjuvant hysterectomy on prognosis in patients with locally advanced cervical cancer treated with concurrent chemoradiotherapy: a meta-analysis

Objective

Few data exist regarding adjuvant hysterectomy (AH) in locally advanced cervical cancer (LACC) patients treated with chemoradiotherapy. We investigated the effect of AH on prognosis in LACC patients, through meta-analysis.

Methods

EMBASE and MEDLINE databases and the Cochrane Library were searched for published studies comparing LACC patients who received AH after chemoradiotherapy with those who did not, through April 2016. Endpoints were mortality and recurrence rates. For pooled estimates of the effect of AH on mortality/recurrence, random- or fixed-effects meta-analytical models were used.

Results

Two randomized trials and six observational studies (AH following chemoradiotherapy, 630 patients; chemoradiotherapy, 585 patients) met our search criteria. Fixed-effects model-based meta-analysis indicated no significant difference in mortality between the groups (odds ratio [OR]=1.01; 95% confidence interval [CI]=0.58–1.78; p=0.968) with low cross-study heterogeneity (p=0.73 and I²=0.0). This pattern was observed in subgroup analysis for study design, radiation type, response after chemoradiotherapy, and hysterectomy type. The pooled OR for AH and recurrence was 0.59 (95% CI=0.44–0.79; p<0.05) with low cross-study heterogeneity (p=0.29 and I²=17.8), favoring the AH group. However, this pattern was not observed in the subgroup analysis for the randomized trials. There was no evidence of publication bias.

Conclusion

In this meta-analysis, AH following chemoradiotherapy did not improve survival in patients with LACC, although it seemed to reduce the risk of recurrence. Concerning the significant morbidity of AH after chemoradiotherapy, routine use of AH should be avoided.

Locally Advanced Cervical Cancer in Pregnancy: Overcoming the Challenge. A Case Series and Review of the Literature

OBJECTIVE

Cervical cancer is the most common gynecological cancer occurring in pregnancy, creating a complex situation both for patient and physician. Neoadjuvant chemotherapy is an innovative way of managing cervical cancer in pregnancy.

METHODS

In our paper, we report a retrospective case series of 4 women treated with chemotherapy for invasive cervical cancer during pregnancy in our center over the last 5 years, and we summarize the available literature and guidelines.

RESULTS

All the cases were locally advanced cervical cancers that received chemotherapy with platinum and/or taxanes. All patients showed a good response to chemotherapy and a radical surgery was performed with no additional morbidities at the cesarean delivery time in 3 of 4 cases. Three of 4 patients are alive and have a good outcome with no recurrence of disease up to date. One patient died because of recurrent disease 2 years after the first-line treatment during pregnancy. All babies are alive and well up to date (maximum follow-up, 63 months).

CONCLUSIONS

Even if there are no standardized practices in the treatment of cervical cancer in pregnancy, in our opinion, neoadjuvant chemotherapy can be a very useful strategy for patients and physicians facing the challenge.

Preoperative Chemoradiotherapy in Locally Advanced Bulky Squamous Cell Carcinoma of the Uterine Cervix

OBJECTIVES

The aim of this study was to evaluate long-term survival and feasibility in patients with bulky squamous cell carcinoma of the uterine cervix who underwent surgery after concurrent chemoradiotherapy.

METHODS

A review of patients with locally advanced bulky squamous cell cervical cancer who underwent chemoradiation followed by surgery with pelvic lymphadenectomy was performed. Chemoradiotherapy included 2 monthly doses of intra-arterial chemotherapy with cisplatin (50 mg/m) and mitomycin C (10 mg/body) and external irradiation to the whole pelvis and high-dose-rate brachytherapy. From 2000 to 2006, 23 patients were enrolled in a single institution. Patient distribution according to the International Federation of Gynecology and Obstetrics stage was as follows: 9 stage IB2, 10 stage IIB, and 4 stage IIIB. Radiological lymph node involvement was present in 69.6% (16/23), including 2 cases of para-aortic lymph node swelling. The radiological response, pathological response, overall and disease-free survival, and late complications were assessed.

RESULTS

Among the patients, 12 (52.2%) showed pathological complete response, and 11 (47.8%) showed a pathological partial response for cervical lesions. Among the cases of radiological pelvic lymph node swelling, the response rate was 93.3% (14/15). Only 1 case showed viable cancer cells in the resected pelvic lymph nodes among radiological complete response cases. In the median follow-up duration (121 months; range, 17-180 months), the 5-year overall survival and disease-free survival were 95.7% and 86.7%, respectively. Seven events in 4 patients led to the development of postoperative fistula formation requiring a rescue surgery.

CONCLUSIONS

Chemoradiotherapy followed by surgery was effective for patients with bulky squamous cell carcinoma of the uterine cervix. Further investigation to select suitable patients for this multimodal treatment will be required.

Could lymphadenectomy be avoided in locally advanced cervical cancer patients administered preoperative chemoradiation? A large-scale retrospective study

INTRODUCTION

To identify a subset of cervical cancer (CC) patients administered chemoradiation (CT/RT) plus radical surgery (RS), who can be spared lymphadenectomy, and complications.

PATIENTS AND METHODS

430 Stage IB2-IIB patients without LN involvement at imaging were accrued (March 1996-December 2015) at Gynecologic Oncology Unit of the Catholic University of Rome/Campobasso. CT/RT consisted of pelvic irradiation plus cisplatin based chemotherapy. Objective response was evaluated according to RECIST criteria; radical hysterectomy and pelvic ± aortic lymphadenectomy was attempted in patients achieving response or stable disease. Surgical morbidity was classified according to the Chassagne grading system.

RESULTS

421 cases underwent RS; metastatic pelvic and aortic LNs were documented in 10.7%, and 8.8% of cases, respectively. In patients without residual tumor in the cervix, there was only 1 case (0.53%) with positive pelvic LNs, and 1 case (2.3%) with metastatic aortic LNs. Analysis of patients according to pre- and post-CT/RT imaging was able to select cases without any metastatic LNs: in patients with negative pelvic LNs at pre- and post-CT/RT imaging, none of cases without residual disease in the cervix had metastatic pelvic or aortic LNs. Of 149 early complications, 76 (51.0%) were lymphovascular. The most frequent late complications were lymphovascular (N = 25/61, 41.0%).

CONCLUSION

Lymphadenectomy could be avoided in stage IB2-IIB CC patients undergoing preoperative CT/RT, when a careful evaluation of pre- and post-CT/RT imaging and histological assessment of no residual disease in the cervix is made. This approach may avoid lymphadenectomy in 40% of patients with a favourable impact on lymphovascular morbidity.

The relevance of prelamin A and RAD51 as molecular biomarkers in cervical cancer

Along with their role in the maintenance of nuclear architecture, nuclear lamins also control genomic stability, DNA damage repair, transcription, cell proliferation, differentiation and senescence. Recent reports reveal that prelamin A–processing defects play a role in cancer development by impacting on transcription of key players in the maintenance of the genome stability, including RAD51. Here, we performed a ‘proof of concept’ study evaluating the role of prelamin A and RAD51 expression in clinical outcome of cervical cancer patients. We analyzed biomarker expression by immunohistochemistry in tumor material from locally advanced cervical cancer (LACC) patients (n=66) and correlated data with clinicopathological parameters and with response to neoadjuvant chemoradiation (CT/RT). In LACC patients who underwent neoadjuvant CT/RT the percentage of cases showing high prelamin A levels was greater in patients who completely responded to treatment (25 of 40, 62.5%) than in patients with macroscopic residual tumor (6 of 26, 23.1%, p=0.0024). Conversely, patients showing high RAD51 expression were less likely to respond to treatment (14 of 26, 53.8%) than were those with low protein levels (12 of 40, 30%, p=0.072). Only prelamin A retained an independent role in predicting response to treatment (p=0.003), while RAD51 approached statistical significance (p=0.07). Notably, high RAD51 expression highly significantly predicted poor outcome, emerging as an independent prognostic factor for disease free survival (p=0.038), while approaching statistical significance for overall survival (p=0.09). Our findings provide a framework for future prospective studies investigating molecular predictors of response to neoadjuvant chemoradiotherapy in LACC patients.

Impact of HPV vaccination: health gains in the Italian female population

Background

Human papillomavirus (HPV) is the leading cause of cervical cancer and other malignant and benign neoplastic lesions. HPV vaccination has three potential goals: to prevent transmission, infection, and disease. At present, there are no available data about health consequences of HPV immunization in Italy. The aim of this study is to evaluate the effect of current HPV vaccination strategy in Italy.

Methods

A multistate morbidity-mortality model was developed to estimate the infection process in a theoretical cohort of Italian women. The Markov process considered nine health states (health, anogenital warts, grade 1 and grade 2/3 cervical intraepithelial neoplasia, cervical cancer, anal cancer, death due to cervical cancer, anal cancer and other causes), and 26 transition probabilities for each age group. The model was informed with the available data in national and international literature. Effectiveness of immunization was assumed considering a literature review pertaining to models and vaccination coverage rates observed in Italy. Life expectancy (e_x), Quality-Adjusted Life Years (QALYs), Disability-Adjusted Life Years (DALYs), and attributable risk (AR) were estimated for no intervention (cervical cancer screening) and vaccination strategies scenarios.

Results

The model showed that in a cohort of 100,000 Italian women the e₀ is equal to 83.1 years. With current HPV vaccination strategy the e₀ achieves 83.2 (+0.1) years. When HPV-related diseases are considered altogether, the QALYs increase from 82.7 to 82.9 (+0.2 QALYs) with no intervention and vaccination strategies respectively. DALYs decrease by 0.6 due to vaccination. Finally, AR is equal to 93 and 265 cases per 100,000 women in population and not vaccinated, respectively.

Conclusion

When mortality due to cervical cancer is considered, HPV vaccination seems to have a low impact on health unit gains in the Italian female population. Conversely, when several HPV-related and cancer morbidity conditions are included, the effect of vaccination becomes quite remarkable.

Robotic Radical Hysterectomy After Concomitant Chemoradiation in Locally Advanced Cervical Cancer: A Prospective Phase II Study

STUDY OBJECTIVE

To assess the feasibility of total robotic radical surgery (TRRS) in patients with locally advanced cervical cancer (LACC) who receive chemoradiation therapy (CT/RT).

DESIGN

A prospective (preplanned) study of a nonrandomized controlled trial (Canadian Task Force classification level 2).

SETTING

Catholic University of the Sacred Hearth, Rome, Italy.

PATIENTS

Between September 2013 and January 2016, a total of 40 patients with LACC (Fédération Internationale de Gynécologie et d'Obstétrique stage IB2-III) were enrolled in the study.

INTERVENTIONS

Robotic radical hysterectomy (RRH) plus pelvic and/or aortic lymphadenectomy was attempted within 6 weeks after CT/RT. The feasibility of TRRS as well as the rate, pattern, and severity of early and late postoperative complications were analyzed.

MEASUREMENTS AND MAIN RESULTS

After CT/RT, 29 patients (72.5%) underwent type B2 RRH, and 11 (27.5%) underwent type C1 RRH. Pelvic lymphadenectomy was performed in all cases. TRRS was successful in 39 of 40 cases (feasibility rate = 97.5%). In patients successfully completing TRRS, the median operating time was 185 minutes (range, 100-330 minutes), and the median blood loss was 100 mL (range, 50-300 mL). The median time of hospitalization counted from the first postoperative day was 2 days (range, 1-4 days). No intraoperative complications were recorded. During the observation period (median = 18 months; range, 4-28 months), 9 of 40 (22.5%) experienced postoperative complications, for a total number of 12 complications. As of April 2016, recurrence of disease was documented in 5 cases (12.5%).

CONCLUSION

TRRS is feasible in LACC patients administered preoperative CT/RT, providing perioperative outcomes comparable with those registered in early-stage disease, and LACC patients receiving neoadjuvant chemotherapy.

Radical hysterectomy after chemoradiation in FIGO stage III cervical cancer patients versus chemoradiation and brachytherapy: Complications and 3-years survival

BACKGROUND

To compare patterns and rates of early and late complications, and survival outcome in FIGO stage III cervical cancer patients underwent to radical hysterectomy after chemo-radiation (CT-RT) vs. chemo-radiation alone.

METHODS

Between May 1996 and April 2013 150 FIGO stage III cervical cancer patients were treated. We divide patients according to type of treatment: 77 were submitted to standard treatment (Group A), and 73 to completion hysterectomy after chemo-radiation (Group B).

RESULTS

The baseline characteristics of the 2 groups were superimposable. We observed lower intra-operative and treatment-related early urinary and gastro-intestinal complications in Group B with respect to Group A (p < 0.001). Vascular complications were registered only in Group B (p < 0.001). We found a significantly higher rate of local recurrences in the Group A than in the Group B (p < 0.002). We registered 29 deaths in the Group A and 22 in the Group B (p = 0.021). The 3-years disease-free survival rate in the Group A and in the Group B was 62.9% and 68.3%, respectively (p = 0.686), and the 3-years overall survival rate in the Group A and in the Group B was 63.2% and 67.7%, respectively (p = 0.675).

CONCLUSIONS

This study confirms that radical hysterectomy after CT-RT is an effective therapeutic approach for advanced cervical cancer. Further prospective and randomized studies should be performed in order to solve the question about the standard approach, and how the different pattern of complication could impact on the quality of life.

Genomic profile predicts the efficacy of neoadjuvant chemotherapy for cervical cancer patients

BACKGROUND

Neoadjuvant chemotherapy (NAC) using platinum and irinotecan (CPT-11) followed by radical excision has been shown to be a valid treatment for locally advanced squamous cervical cancer (SCC) patients. However, in NAC-resistant or NAC-toxic cases, surgical treatment or radiotherapy might be delayed and the prognosis may be adversely affected. Therefore, it is important to establish a method to predict the efficacy of NAC.

METHODS

Gene expression microarrays of SCC tissue samples (n = 12) and UGT1A1 genotyping of blood samples (n = 23) were investigated in terms of their association with NAC sensitivity. Gene expression and drug sensitivity of SCC cell lines were analyzed for validation.

RESULTS

Microarray analysis revealed that the glutathione metabolic pathway (GMP) was significantly up-regulated in NAC-resistant patients (p < 0.01), and there was a positive correlation between 50 % growth inhibitory concentrations of CPT-11 and predictive scores of GMP activation in SCC cells (r = 0.32, p < 0.05). The intracellular glutathione (GSH) concentration showed a highly positive correlation with GMP scores among 4 SCC cell lines (r = 0.72). UGT1A1 genotyping revealed that patients with UGT1A1 polymorphisms exhibited significantly higher response rates to NAC than those with the wild-type (79.5 vs. 49.5 %, respectively, p < 0.05).

CONCLUSIONS

These results indicate that GMP scores of cancerous tissue combined with UGT1A1 genotyping of blood samples may serve as highly potent markers for predicting the efficacy of NAC for individual SCC patients.

Intensity-modulated extended-field chemoradiation plus simultaneous integrated boost in the pre-operative treatment of locally advanced cervical cancer: a dose-escalation study

OBJECTIVE

To investigate the feasibility and determine the recommended pre-operative intensity-modulated radiotherapy (IMRT) dose of extended-field chemoradiation along with simultaneous integrated boost (SIB) dose escalation.

METHODS

A radiation dose of 40 Gy over 4 weeks, 2 Gy/fraction, was delivered to the tumour and the lymphatic drainage (planning target volume, PTV3), which encompassed a volume larger than standard (common iliac lymphatic area up to its apex, in front of the L3 vertebra), concurrently with chemotherapy (cisplatin and 5-fluorouracil). Radiation dose was escalated to the pelvis (PTV2) and to the macroscopic disease (PTV1) with the SIB-IMRT strategy. Three dose levels were planned: Level 1 (PTV3: 40/2 Gy; PTV2: 40/2 Gy; PTV1: 45/2.25 Gy), Level 2 (PTV3: 40/2 Gy; PTV2: 45/2.25 Gy; PTV1: 45/2.25 Gy) and Level 3 (PTV3: 40/2 Gy; PTV2: 45/2.25 Gy; PTV1: 50/2.5 Gy). All treatments were delivered in 20 fractions. Patients were treated in cohorts of between three and six per group using a Phase I study design. The recommended dose was exceeded if two of the six patients in a cohort experienced dose-limiting toxicity within 3 months from treatment.

RESULTS

19 patients [median age: 46 years; The International Federation of Gynecology and Obstetrics (FIGO) stage IB2: 3, IIB: 10, IIIA-IIIB: 6] were enrolled. Median follow-up was 24 months (9-60 months). The most common grade 3/4 toxicity was gastrointestinal (GI) (diarrhoea, mucous discharge, rectal/abdominal pain). At Levels 1 and 2, only one grade 3 GI toxicity per level was recorded, whereas at Level 3, two grade 3 GI toxicities (diarrhoea, emesis and nausea) were recorded.

CONCLUSION

The SIB-IMRT technique was found to be feasible and safe at the recommended doses of 45 Gy to PTV1 and PTV2 and 40 Gy to PTV3 in the pre-operative treatment of patients with locally advanced cervical cancer. Unfortunately, this complex technique was unable to safely escalate dose beyond levels already achieved with three-dimensional conformal radiotherapy technique given acute GI toxicity.

ADVANCES IN KNOWLEDGE

A Phase I radiotherapy dose-escalation trial with SIB-IMRT technique is proposed in cervical cancer. This complex technique is feasible and safe at the recommended doses.

Hysterectomy with radiotherapy or chemotherapy or both for women with locally advanced cervical cancer

BACKGROUND

Cervical cancer is the second commonest cancer among women up to 65 years of age and is the most frequent cause of death from gynaecological cancers worldwide. Sources suggest that a very high proportion of new cervical cancer cases in developing countries are at an advanced stage (IB2 or more) and more than a half of these may be stage III or IV. Cervical cancer staging is based on findings from clinical examination (FIGO) staging). Standard care in Europe and US for stage IB2 to III is non-surgical treatment (chemoradiation). However in developing countries, where there is limited access to radiotherapy, locally advanced cervical cancer may be treated with a combination of chemotherapy and hysterectomy (surgery to remove the womb and the neck of the womb, with or without the surrounding tissues). It is not certain if this improves survival. Therefore, it is important to systematically assess the value of hysterectomy in addition to radiotherapy or chemotherapy, or both, as an alternative intervention in the treatment of locally advanced cervical cancer (stage IB2 to III).

OBJECTIVES

To determine whether hysterectomy, in addition to standard treatment with radiation or chemotherapy, or both, in women with locally advanced cervical cancer (stage IB2 to III) is safe and effective compared with standard treatment alone.

SEARCH METHODS

We searched the Cochrane Gynaecological Cancer Group Trials Register, CENTRAL, MEDLINE, EMBASE and LILACS up to February 2014. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies.

SELECTION CRITERIA

We searched for randomised controlled trials (RCTs) that compared treatment protocols involving hysterectomy versus radiotherapy or chemotherapy, or both, in women with advanced stage (IB2 to III) cervical cancer presenting for the first time.

DATA COLLECTION AND ANALYSIS

We assessed study eligibility independently, extracted data and assessed risk of bias. Where possible, overall and progression or disease-free survival outcomes were synthesised in a meta-analysis using the random-effects model. Adverse events were incompletely reported so results of single trials were described in narrative form.

MAIN RESULTS

We included seven RCTs (1217 women) of varying methodological quality in the review; most trials were at moderate or high risk of bias.Three were multi-centre trials, two were single-centre trials, and in two trials it was unclear if they were single or multi-centre. These trials compared the following interventions for women with locally advanced cervical cancer (stages IB2 to III):hysterectomy (simple or radical) with radiotherapy (N = 194) versus radiotherapy alone (N = 180); hysterectomy (simple or radical) with chemoradiotherapy (N = 31) versus chemoradiotherapy alone (N = 30); hysterectomy (radical) with chemoradiotherapy (N = 111) versus internal radiotherapy with chemoradiotherapy (N = 100); hysterectomy (simple or radical) with upfront (neoadjuvant) chemotherapy (N = 298) versus radiotherapy alone (N = 273).One trial (N = 256) found no difference in the risk of death or disease progression between women who received attenuated radiotherapy followed by hysterectomy and those who received radiotherapy (external and internal) alone (hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.61 to 1.29). This trial also reported no difference between the two groups in terms of adverse effects (18/129 grade 3 or 4 adverse effects in the hysterectomy and radiation group and 19 cases in 18/121 women in the radiotherapy alone group). There was no difference in 5-year tumour-free actuarial survival (representation of the probable years of survivorship of a defined population of participants) or severe complications (grade 3) in another trial (N = 118) which reported the same comparison (6/62 versus 6/56 in the radiation with surgery group versus the radiotherapy alone group, respectively). The quality of the evidence was low for all these outcomes.One trial (N = 61) reported no difference (P value > 0.10) in overall and recurrence-free survival at 3 years between chemoradiotherapy and hysterectomy versus chemoradiotherapy alone (low quality evidence). Adverse events and morbidity data were not reported.Similarly, another trial (N = 211) found no difference in the risk of death (HR 0.65, 95% CI 0.35 to 1.21, P value = 0.19, low quality evidence), disease progression (HR 0.70, 95% CI 0.31 to 1.34, P value = 0.24, low quality evidence) or severe late complications (P value = 0.53, low quality evidence) between women who received internal radiotherapy versus hysterectomy after both groups had received external-beam chemoradiotherapy.Meta analysis of three trials of neoadjuvant chemotherapy and hysterectomy versus radiotherapy alone, assessing 571 participants, found that women who received neoadjuvant chemotherapy plus hysterectomy had less risk of death than those who received radiotherapy alone (HR 0.71, 95% CI 0.55 to 0.93, I(2) = 0%, moderate quality evidence). However, a significant number of the participants that received neoadjuvant chemotherapy plus hysterectomy had radiotherapy as well. There was no difference in the proportion of women with disease progression or recurrence between the two groups (RR 0.75, 95% CI 0.53 to 1.05, I(2) = 20%, moderate quality evidence).Results of single trials reported no apparent (P value > 0.05) difference in long-term severe complications, grade 3 acute toxicity and severe late toxicity between the two groups (low quality evidence).Quality of life outcomes were not reported in any of the trials.

AUTHORS' CONCLUSIONS

From the available RCTs, we found insufficient evidence that hysterectomy with radiotherapy, with or without chemotherapy, improves the survival of women with locally advanced cervical cancer who are treated with radiotherapy or chemoradiotherapy alone. The overall quality of the evidence was variable across the different outcomes and was universally downgraded due to concerns about risk of bias. The quality of the evidence for neoadjuvant chemotherapy and radical hysterectomy versus radiotherapy alone for survival outcomes was moderate, with evidence from other comparisons of low quality. This was mainly based on poor reporting and sparseness of data where results were based on single trials. More trials that assess medical management with and without hysterectomy may test the robustness of the findings of this review as further research is likely to have an important impact on our confidence in the estimate of effect.

Long follow-up of patients with locally advanced cervical cancer treated with concomitant chemobrachyradiotherapy with cisplatin and ifosfamide followed by consolidation chemotherapy

OBJECTIVES

Locally advanced cervical cancer (LACC) is one of the leading health problems of the developing countries. We present long-term outcomes of treatment with a concomitant chemobrachyradiotherapy followed by consolidation chemotherapy regimen.

MATERIALS AND METHODS

We treated 118 patients with LACC (International Federation of Gynecology and Obstetrics stages IB2-IVA) with external radiotherapy (50 Gy in 25 fractions) and concomitant chemobrachyradiotherapy (low-dose rate). Chemotherapy was applied during brachyradiotherapy (cisplatin on day 1 in combination with 24-hour infusion of ifosfamide and mesna uroprotection). Four cycles of consolidation chemotherapy were given starting 4 weeks after the second concomitant chemobrachyradiotherapy cycle.

RESULTS

After median follow-up period of 99.3 months, we observed acceptable acute and late toxicity, local control rate of 97.5%, and an overall survival of 74.6% at 96 months.

CONCLUSIONS

Chemobrachyradiotherapy regimen followed by consolidation chemotherapy described in this article is a valuable treatment option for LACC.
