Risk factors for poor prognosis in microinvasive adenocarcinoma of the uterine cervix (IA1 and IA2): A pooled analysis

Clinical Epidemiology of Microinvasive Cervical Carcinoma in an Italian Population Targeted by a Screening Programme

Simple Summary

According to this population-based study, 3750 patients living in the Emilia-Romagna Region (northern Italy) were registered with cervical carcinoma between 1995–2016, including 2942 eligible patients. The likelihood of stage IA cervical carcinoma (n = 876, 29.8%) did not change over time, decreased with increasing patient age, and was lower for patients with adenocarcinoma and grade 3–4 disease. Three hundred and fifty (40.0%) patients had a conservative treatment, 317 (36.2%) had hysterectomy, 197 (22.5%) had hysterectomy with lymph node dissection (LND), and 12 (1.4%) had a conservative treatment with LND. The proportion of hysterectomy decreased from 70.6% in 1995–1999 to 46.9% in 2011–2016. The likelihood of hysterectomy increased above the age of 40. Among screening-aged (25–64 years) patients, the likelihood of hysterectomy did not differ between screen-detected and non-screen-detected ones. Hysterectomy was increasingly combined with LND. High tumour grade was the strongest determinant of LND during hysterectomy.

Abstract

(1) Background: This population-based study aimed at identifying the factors associated with the likelihood of detection of stage IA cervical carcinoma—versus the detection of stage IB through IV cervical carcinoma—and the patterns of surgical treatment. (2) Methods: Between 1995–2016, 3750 patients living in the Emilia-Romagna Region (northern Italy) were registered with cervical carcinoma, including 2942 eligible patients (median age, 53). Multivariate analysis was performed using binary logistic regression models. (3) Results: The likelihood of stage IA cervical carcinoma (n = 876, 29.8%) did not change over time, decreased with increasing patient age, and was lower for patients with adenocarcinoma and grade 3–4 disease. Three hundred and fifty (40.0%) patients had a conservative treatment, 317 (36.2%) had hysterectomy, 197 (22.5%) had hysterectomy with lymph node dissection (LND), and 12 (1.4%) had a conservative treatment with LND. The proportion of hysterectomy decreased from 70.6% in 1995–1999 to 46.9% in 2011–2016. The likelihood of hysterectomy increased above the age of 40. Among screening-aged (25–64 years) patients, the likelihood of hysterectomy did not differ between screen-detected and non-screen-detected ones. Hysterectomy was increasingly combined with LND. High tumour grade was the strongest determinant of LND during hysterectomy. (4) Conclusions: This study provided a multifaceted overview of stage IA cervical carcinoma over the last decades.

Human papillomavirus and risk factors for cervical adenocarcinoma in the state of Pernambuco, Brazil

Abstract Objectives: to determine the incidence of the main high oncogenic risk types of the human papillomavirus (HPV) ( 16, 18, 31 and 33) and the risk factors for cervical adenocarcinoma. Methods: a case-control study was carried out with 324 women (69 with adenocarcinoma and 260 healthy controls) between 2001 and 2014. Information on risk factors associated with adenocarcinomawere collected and the detection performed on HPVby using Polymerase Chain Reaction (PCR) method. Results: adenocarcinoma was associated with age ≥40 years old (OR=2.95; 95%CI=1.13-7.71), ≤3 years of schooling (OR=2.34; 95%CI=1.02-5.37), presence of HPV (OR=6.75; 95%CI=2.41-18.91),women in menopausal status (OR=4.76; 95%CI:1.70-13.31) black race (OR=6.71; 95%CI= 2.11-21.32) and never had undergone cervical cancer screening (OR=9.92; 95%CI:2.41-40.81). Andamong the HPV types detected, HPV 18 was observed to be strongly associated with adenocarcinoma of the cervix (OR=99.1; 95%CI=12.96-757.78). Conclusions: the factors associated with cervical adenocarcinoma were ≥40 years old, ≤3 years of schooling, black race, menopausal status, never had undergone cervical cancer screening and the presence of HPV.

The safety of fertility preservation for microinvasive cervical adenocarcinoma: a meta-analysis and trial sequential analysis

PURPOSE

This study sought to evaluate the safety of conservative treatment in the management of patients with microinvasive cervical adenocarcinoma.

METHODS

The PubMed, PMC, EMBASE, Web of Science and Cochrane databases were searched to collect correlational studies published in English between January 1949 and May 2018. Series reports that evaluating the oncological prognoses of patients with microinvasive cervical adenocarcinoma who were treated with fertility-sparing surgery versus hysterectomy were pooled for meta-analysis and trial sequential analysis.

RESULTS

A total of 8 articles with 1256 patients were collected, including 7 retrospective reviews and 1 prospective study. Only one (0.08%) patient had parametrial involvement. Positive margins of surgical specimens were identified in 6 patients (2.2%). Lymph node metastasis was found in 5 patients (0.4%). The progression-free survival and overall survival rates were 99.3 and 98.2%. Fertility-sparing surgery had no adverse impact on recurrence or survival (P = 0.524 and 0.485, respectively). Regarding potential selection bias, significantly more patients with stage IA2 tumors than those with stage IA1 disease were treated with hysterectomy (P < 0.001). The trial sequential analysis indicated that the cumulative number of patients failed to meet the required sample size (number of patients).

CONCLUSIONS

The prognosis for patients with microinvasive cervical adenocarcinoma is excellent. Fertility preservation is at least appropriate for young women with stage IA1 adenocarcinoma. Further studies are still warranted to evaluate the safety of this procedure in managing patients with microinvasive cervical adenocarcinoma.

Brachytherapy Improves Survival in Stage III Endometrial Cancer With Cervical Involvement

PURPOSE

To evaluate the survival benefit of adding vaginal brachytherapy (BT) to pelvic external beam radiation therapy (EBRT) in women with stage III endometrial cancer.

METHODS AND MATERIALS

The National Cancer Data Base was used to identify patients with stage III endometrial cancer from 2004 to 2013. Only women who received adjuvant EBRT were analyzed. Women were grouped according to receipt of BT. Logistic regression modeling was used to identify predictors of receiving BT. Log-rank statistics were used to compare survival outcomes. Cox proportional hazards modeling was used to evaluate the effect of BT on survival. A propensity score-matched analysis was also conducted among women with cervical involvement.

RESULTS

We evaluated 12,988 patients with stage III endometrial carcinoma, 39% of whom received EBRT plus BT. Women who received BT were more likely to have endocervical or cervical stromal involvement (odds ratios 2.03 and 1.77; P<.01, respectively). For patients receiving EBRT alone, the 5-year survival was 66% versus 69% with the addition of BT at 5 years (P<.01). Brachytherapy remained significantly predictive of decreased risk of death (hazard ratio 0.86; P<.01) on multivariate Cox regression. The addition of BT to EBRT did not affect survival among women without cervical involvement (P=.84). For women with endocervical or cervical stromal invasion, the addition of BT significantly improved survival (log-rank P<.01). Receipt of EBRT plus BT was associated with improved survival in women with positive and negative surgical margins, and receiving chemotherapy did not alter the benefit of BT. Propensity score-matched analysis results confirmed the benefit of BT among women with cervical involvement (hazard ratio 0.80; P=.01).

CONCLUSIONS

In this population of women with stage III endometrial cancer the addition of BT to EBRT was associated with an improvement in survival for women with endocervical or cervical stromal invasion.

Conservative treatment of coexisting microinvasive squamous and adenocarcinoma of the cervix: report of two cases and literature review

Coexistence of microinvasive squamous cell carcinoma (MISCC) and microinvasive adenocarcinoma (MIAC) of the cervix is a rare phenomenon with very few clinically significant cases described in the literature. While a conservative approach has been studied, and may be effective in MISCC, a lower number of studies that recommend conservative treatment are available for MIAC. We report two cases of synchronous cervix lesions in two separate foci, MISCC and MIAC, who underwent fertility-sparing treatment with long-term follow-up. We describe clinical, histological, and immunohistochemical features of the two cases. The first case is a 41-year-old female with a diagnosis of MIAC of endocervical type, grade 1 differentiation, with a stromal invasion, associated with a separate area of squamous cell carcinoma (International Federation of Gynecology and Obstetrics/TNM stage: pT1a1G1). The second case is a 45-year-old female with a diagnosis of plurifocal MISCC, associated with an MIAC of endocervical type with a stromal invasion (International Federation of Gynecology and Obstetrics/TNM stage: pT1a1G1). After multidisciplinary counseling, both patients accepted conization as definitive treatment. Eleven years after the conization, all tests (Papanicolaou smear, colposcopy, cervical curettage, and hybrid capture 2-human papillomavirus test) planned quarterly in the first year and every 6 months in the subsequent years were negative in both patients. In women affected by stage IA1 squamous cervical cancer coexisting with stage IA1 adenocarcinoma endocervical type, with clear margins, and without lymphovascular space invasion, cervical conization may be considered a fertility-preserving, safe, and definitive therapeutic option.

Residual disease following conization of women with stage IA-IB1 cervical carcinoma in a high incidence region

BACKGROUND

To determine rates of residual disease along with influencing factors in women with stage IA to IB1 cervical carcinoma after conization.

MATERIALS AND METHODS

A retrospective study was conducted of medical records of 198 stage IA to IB1 cervical carcinoma patients who had undergoing cervical conization followed by primary surgical treatment during 2006-2013. Independent factors correlating with residual carcinoma in subsequent surgical specimens were analyzed by stepwise regression analysis.

RESULTS

Mean age was 48.9 years. Cone specimens demonstrated free margins in 36 women (18.8%). In case of having disease at margin, high-grade cervical intraepithelial neoplasia (CIN) and carcinoma were evidenced in 58 and 97 women, respectively. Pathology of subsequent specimens revealed residual carcinoma in 78 women (39.4%), high-grade CIN or adenocarcinoma in situ (AIS) in 45 (22.7%), and no residual pathology in 75 (37.9%). Age more than 35 years, postmenopausal status, having symptoms, diseases or invasive lesions at conization margins or disease on endocervical aspect, and higher stage were significantly correlated with residual cancer in surgical treatment specimens. On regression analysis, postmenopause and stage were independent factors associated with residual carcinoma.

CONCLUSIONS

Patient and tumor characteristics are predictive factors for residual cancer in the studied group of women.

Analysis of treatment modalities and prognosis on microinvasive cervical cancer: a 10-year cohort study in China

OBJECTIVE

To explore appropriate treatment modality of microinvasive cervical cancer (MIC) and to analyze prognosis and risk factors of recurrence.

METHODS

A cohort of 324 Chinese patients with MIC diagnosed and treated at Peking Union Medical College Hospital was retrospectively reviewed. Demographic features, treatment modalities, pathologic parameters, risk factors of residual disease, survival and risk factors of recurrence were analyzed.

RESULTS

Of all patients, 280 cases were staged IA1 and 44 cases staged IA2 MIC. Twenty-five cases (7.7%) were found to have lympho-vascular space involvement (LVSI), but no parametrial involvement or ovarian metastasis was detected. Only one staged IA2 patient with LVSI was found to have lymph node metastasis. 32.4% patients (82/253) had residual diseases after conization. No significant difference of LVSI, lymph node metastasis and residual disease after coniztion was found between stage IA1 and IA2 MIC patients. Multivariate logistic analysis showed positive margin was the only independent risk factor of residual disease after conization (odds ratio [OR], 4.18; p<0.001). Recurrence occurred in five cases, but no mortality was found. Progression-free survival for stage IA1 patients treated by conization or hysterectomy was similar (92.3% and 98.8%, p=0.07). Cox regression analysis revealed LVSI as an independent risk factor for recurrence in stage IA1 patients (OR, 12.14; p=0.01).

CONCLUSION

For stage IA1 patients with negative resection margin and no LVSI, conization can be an ideal treatment modality. For stage IA2 patients, more conservative surgery such as simple hysterectomy may be considered. LVSI is an independent risk factor for recurrence in patients with stage IA1 cervical cancer.

The spectrum of cervical glandular neoplasia and issues in differential diagnosis

CONTEXT

Premalignant and malignant glandular lesions of the cervix are known to often cause diagnostic problems with a variety of benign (more common) as well as other malignant mimics, the latter setting often being represented by secondary involvement by endometrioid endometrial carcinoma especially in small samplings.

OBJECTIVE

To highlight key histologic features and immunohistochemical markers that may be helpful in the distinction of in situ endocervical carcinoma from benign glandular proliferations, and those that separate different subtypes of invasive endocervical carcinoma, as well as invasive carcinoma from other carcinomas secondarily involving the cervix and nonneoplastic proliferations of the cervix.

CONCLUSIONS

Clinical and morphologic features as well as immunohistochemistry results should be used in conjunction in the differential diagnosis of glandular proliferations of the cervix, as correct interpretation has major clinical consequences for the patient in most instances (especially benign versus malignant). Immunohistochemical markers should be used as part of a panel of antibodies, as exceptions may occur to the usual pattern of staining, and if used singly, they may mislead the pathologist to establish a wrong diagnosis.

Conservative Treatment of Stage IA1 Adenocarcinoma of the Uterine Cervix during Pregnancy: Case Report and Review of the Literature

Microinvasive adenocarcinoma (MIAC) of the uterine cervix is rare in pregnancy. Published data on conservative treatment of MIAC both in pregnant and nonpregnant women are scarce. A conservatively treated case of MIAC in a 13-week-pregnant woman after a diagnosis of atypical glandular cells (AGC) on pap smear at the 6th week of pregnancy is presented. The problems of suspected adenocarcinoma in situ (AIS) on biopsy and MIAC on cone biopsy in pregnancy, as well as the risks and benefits of a conservative treatment are discussed. After colposcopic guide laser cervical conization and expression of informed consent the patient underwent followup and vaginal delivery at 40 weeks plus 3 days of gestation. In this case, no obstetric complication has been recorded after the cervical conization, and after a followup of 18 months the patient was alive and free of disease, with negative results as far as pap smear, colposcopy, HPV status, and cervical curettage are concerned. In a stage Ia1 disease of endocervical type, with clear margins and without lymph-vascular space invasion, cervical conization performed during the second trimester may be considered a definitive and safe treatment, at least up to delivery, after expression of informed consent by the woman.

Microinvasive adenocarcinoma of the cervix

OBJECTIVE

We compared the outcomes of microinvasive squamous cell carcinoma and adenocarcinoma of the cervix and examined the safety of fertility-conserving treatment.

STUDY DESIGN

The Surveillance, Epidemiology, and End Results database was used to identify all women with stage IA1 and IA2 cervical carcinoma diagnosed from 1988 to 2005. The treatment and outcomes of women with adenocarcinomas were compared with squamous cell carcinomas.

RESULTS

A total of 3987 women including 988 with adenocarcinomas (24.8%) were identified. Women with adenocarcinoma were more often white and were younger (P < .05 for all). Survival for stage IA1 adenocarcinomas (hazard ratio, 0.79; 95% confidence interval, 0.21-2.94) was similar to that of women with squamous cell tumors. For stage IA2 tumors, survival was similar for squamous cell and adenocarcinomas (hazard ratio, 0.51; 95% confidence interval, 0.18-1.47). For stage IA1 and IA2 adenocarcinomas, survival was similar for conization and hysterectomy.

CONCLUSION

Survival is similar for microinvasive adenocarcinomas and squamous cell carcinomas. Conization appears to be adequate treatment for microinvasive adenocarcinoma.
