Neoadjuvant chemotherapy for advanced stage cervical cancer in a pregnant patient: Report of one case with rapid tumor progression

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.

Treatment and clinical outcomes of cervical cancer during pregnancy

Background

This study aims to investigate clinicopathological factors associated with survival rate and treatment of patients with cervical cancer during pregnancy (CCP).

Methods

A total of 92 patients diagnosed CCP were retrospectively reviewed. One patient was from Nanfang Hospital of Southern Medical University, 5 patients were from Tongji Hospital, and 86 patients were from case reports in the PubMed database from 1961 to 2019. Patients and tumor characteristics were evaluated. Kaplan-Meier and Cox regression methods were used to analyze the 5-year disease-specific survival (DSS).

Results

Most patients (73 cases) were stage I according to the 2018 International Federation of Gynecology and Obstetrics (FIGO) standards. Twelve patients (13.04%) terminated pregnancy once diagnosed. These patients were diagnosed at the mean gestational age (GA) of 11±3 weeks, during early pregnancy. For the rest of the patients (80 cases) who continued pregnancy, the mean GA was 35±2 weeks at delivery. There was a significant difference in survival whether the treatment was performed once diagnosed or not. The 5-year DSS was 75% in adenocarcinoma (AC), 68.5% in squamous cell carcinoma (SCC), and 43.7% in the rare subtype. Among the 38 patients who underwent neoadjuvant chemotherapy (NACT), one patient suffered from spontaneous abortion, and one baby experienced acute myeloid leukemia (AML) ex-FAB (French-American-British)-M7 subtype and received bone marrow transplantation. Other delivered newborns showed no abnormality or malformation. Cox multi-factorial analysis demonstrated that tumor size (2 cm) was an independent overall survival predictor for CCP patients (P<0.05).

Conclusions

Tumor size was an independent prognostic factor of survival in CCP patients. Pregnancy has adverse effects on the prognosis of cervical cancer. Personalized treatment is a priority for CCP patients.

Estrogen stimulates female cancer progression by inducing myeloid-derived suppressive cells: investigations on pregnant and non-pregnant experimental models

Objective

To investigate the clinical implications of 17β-estradiol (E2) in estrogen receptor α (ERα)-negative female cancer progression as well as the underlying biological mechanisms.

Methods

Clinical data from 306 locally-advanced cervical cancer (stage IIB-IVA) patients were analyzed in order to investigate the relationships between age, serum E2 levels, and treatment outcomes. Clinical samples, ERα-negative cervical and breast cancer cell lines, and mouse xenograft models of cervical and breast cancers were employed in order to elucidate the mechanisms responsible for the E2- and pregnancy-mediated progression of cervical and breast cancers, with a focus on the role of myeloid-derived suppressor cells (MDSC).

Results

Younger patients with elevated E2 levels showed significantly shorter progression-free survival (P = 0.040) and overall survival (P = 0.039). The exogenous E2 treatment stimulated the mobilization of MDSC from bone marrow and directly augmented their suppressive activities, leading to the progression of ERα-negative cervical and breast cancers. The co-administration of an anti-Gr-1 neutralizing antibody with E2 prevented the E2-mediated induction of MDSC, and attenuated E2-mediated tumor growth in cervical and breast cancer xenografts. Significantly increased MDSC numbers and enhanced tumor growth were observed during pregnancy in mice with cervical or breast cancer. Significantly increased MDSC numbers were also observed during pregnancy in cervical cancer patients.

Conclusions

E2 facilitates the progression of ERα-negative cervical or breast cancer under non-pregnant and pregnant conditions by inducing MDSC. MDSC inhibition therapy may have therapeutic efficacy in premenopausal or pregnant female cancer patients.

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.

Ovarian dysgerminoma in pregnancy: A case report and literature review

BACKGROUND

Dysgerminoma is an uncommon malignant tumor arising from the germ cells of the ovary. Its association with pregnancy is extremely rare; the incidence is about 0.2-1 per 100,000 pregnancies. Because of its infrequency, there are few recommendations regarding its management in pregnancy; therefore, it is important to discuss and summarize the treatment strategy.

CASE

We presented a case of a 23-year-old pregnant woman with a large dysgerminoma originated from the right ovary, which had the unusual coincidence of being associated with an abdominal desmoid tumor simultaneously. We did not find any similar cases published in the PubMed database after 1947. A cesarean section was performed at 34 + 6 weeks gestation secondary to her abdominal pain worsening. The patient delivered a healthy boy and had fertility-preserving surgery, followed by 6 cycles of chemotherapy. This case is compared with 21 other reported cases of pure ovarian dysgerminoma in the literature to evaluate the clinical characteristics, feto-maternal compromise, treatment, long-term survival, and fertility outcome.

CONCLUSION

The treatment strategy in women with ovarian dysgerminoma should be discussed and structured on an individual basis. If pregnancy is desired, surgical intervention undertaken in the second trimester seems to be the first choice. When chemotherapy is indicated, unless delivery can be accomplished within a few weeks of diagnosis, it should not necessarily be delayed until after delivery. Good reproductive function and high survival rate can be achieved in patients treated with conservative surgery and adjuvant chemotherapy.

Management of Locally Advanced Cervical Cancer in Pregnancy: A Case Report

Background

Carcinoma of the cervix is the most common malignancy associated with pregnancy. In the first and second trimesters patients should receive the same treatment as is used in nonpregnant women and termination is advised. In selected cases neoadjuvant chemotherapy (NACT) could be proposed but only a few cases have been reported.

Case

A 27-year-old woman, gravida 1 para 0, at 15 weeks' gestation, was diagnosed with FIGO stage IB2 squamous cervical cancer. After refusing to terminate pregnancy, she was treated with neoadjuvant chemotherapy (cisplatin) starting at 18 weeks. A cesarean section with radical surgery was performed at 32 weeks and a healthy baby delivered. Four weeks later the patient started chemoradiation therapy. She relapsed 1 year after surgery and died when her child was 2 years old.

Conclusion

NACT followed by radical surgery was an unsuccessful treatment in our patient; platinum-based chemotherapy was harmless to the child up to the last follow-up.

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.

Does Chemotherapy for Gynecological Malignancies during Pregnancy Cause Fetal Growth Restriction?

Cancer and pregnancy rarely coincide. Gynecological cancers are among the most common malignancies to occur during pregnancy, and chemotherapy with or without surgery is the primary treatment option. The main concern of administering chemotherapy during pregnancy is congenital malformation, although it can be avoided by delaying treatment until after organogenesis. The dose, frequency, choice of chemotherapeutic agents, time of treatment commencement, and method of administration can be adjusted to obtain the best maternal treatment outcomes while simultaneously minimizing fetal toxicity. Use of chemotherapy after the first trimester, while seemingly safe, can cause fetal growth restriction. However, the exact effect of chemotherapy on such fetal growth restriction has not been fully established; information is scarce owing to the rarity of malignancy occurring during pregnancy, the lack of uniform treatment protocols, different terminologies for defining certain fetal growth abnormalities, the influence of mothers' preferred options, and ethical issues. Herein, we present up-to-date findings from the literature regarding the impact of chemotherapy on fetal growth.

Treatment and prognosis of cervical cancer associated with pregnancy: analysis of 20 cases from a Chinese tumor institution

This study was designed to investigate the therapeutic approaches and prognosis for cervical cancer associated with pregnancy. Clinical information, therapeutic strategies, and follow-up results of 20 patients with cervical cancer associated with pregnancy from Jan. 2000 to June 2009 in the Zhejiang Cancer Hospital were retrospectively analyzed. The International Federation of Gynecology and Obstetrics (FIGO) stages were: in situ (n=1), stage IA1 (n=1), stage IB1 (n=5), stage IB2 (n=1), stage IIA (n=8), stage IIB (n=3), and stage IIIB (n=1). Eight patients were in the first trimester of pregnancy, four in the second, two in the third, and six at postpartum when diagnosed. The therapeutic strategies were either single or combined modalities, including surgery, radiotherapy, and chemotherapy. Fourteen patients survived, five patients died (four of remote metastasis and one of uremia), and one patient was lost to follow-up. One newborn from a patient at stage IIA carcinoma in the third trimester with postponed therapy six weeks after diagnosis survived. Retarded fetal growth was observed in one patient receiving neoadjuvant chemotherapy and cesarean section. Out of the six postpartum patients, three underwent cesarean section and survived, whereas only one out of the three who underwent vaginal delivery survived. The remaining two died of remote metastasis. Therefore, personalized treatment is necessary for cervical cancer associated with pregnancy. Cervical cancer patients in the third trimester of pregnancy can continue the pregnancy for a short period of time. There may be potential risk for the fetus by chemotherapy during pregnancy. Cesarean section is the preferred mode of delivery for pregnant cervical cancer patients.

Individual management of cervical cancer in pregnancy

Purpose

The management of cervical cancer in pregnancy persists to be challenging. Therefore, identification of factors that influence the choice of therapeutic management is pivotal for an adequate patient counseling.

Methods

We present a literature review of 26 studies reporting 121 pregnancies affected by cervical cancer. Additionally, we add a retrospective case series of five patients with pregnancy-associated cervical cancer diagnosed and treated in our clinic between 2006 and 2013.

Results

The literature review revealed that the therapeutic management during pregnancy varies according to the gestational age at diagnosis, while in the postpartum period no influence on the treatment choice could be detected. Also in our case series the choice of oncologic therapy was influenced by the gestational age, the wish to continue the pregnancy and the risks of delaying definitive treatment.

Conclusions

There are no standardized procedures concerning the treatment of cervical cancer in pregnancy. Therefore, in consultation with the patient and a multidisciplinary team, an adequate individualized treatment plan should be determined.

How much platinum passes the placental barrier? Analysis of platinum applications in 21 patients with cervical cancer during pregnancy

OBJECTIVE

Cervical cancer is the most common solid cancer diagnosed in pregnancy. Platinum is an active drug in the treatment of patients with cervical cancer. In the second and third trimesters, platinum is used to prevent cancer progression until fetal maturity is reached. However, knowledge about the transplacental passage of platinum is very limited.

STUDY DESIGN

Between May 2008 and June 2014, platinum-based neoadjuvant chemotherapy was applied to 21 consecutive patients with cervical cancer diagnosed in their second trimester. At the time of delivery by cesarean delivery, synchronous samples from maternal blood, umbilical cord blood, and amniotic fluid were taken and analyzed for platinum concentrations.

RESULTS

The mean week of gestation at cancer diagnosis was 17 (13-23). On average 3 (range, 2-4) cycles of chemotherapy were applied. Cesarean deliveries were carried out between 30.4 and 36.5 weeks of gestation. Twenty-two healthy babies without renal, hepatic, auditory, or hematopoietic impairment were delivered. Platinum concentrations in umbilical cord blood and amniotic fluid were 23-65% and 11-42% of the maternal blood, respectively.

CONCLUSION

This series on in vivo measurement of platinum concentrations in the fetomaternal compartment observed that because of consistently lower platinum values in the fetoplacental unit, a placental filtration mechanism of platinum may be assumed.

Cervical Carcinoma in Early Pregnancy - Successful Birth by Caesarean Section Followed by Radical Hysterectomy

A cervical carcinoma was diagnosed in a 32-year-old patient in the 17th week of her pregnancy. The histological confirmation revealed a well-differentiated squamous cell carcinoma. It was a clinical stage Ib1 tumour, without enlarged lymph nodes according to the image. After a staging MRI, intensive education of the patient and case discussion at the interdisciplinary tumour board as well as consultation with the neonatologist, it was agreed to prolong the pregnancy under close monitoring. The carcinoma was confined to the cervix in the further course of the pregnancy. The elective delivery was planned after 32 weeks of gestation. The primary Caesarean section followed by radical hysterectomy Piver II were carried out without complications. After regular postoperative progression of the mother, brachytherapy was performed at the appropriate time. The premature newborn was under neonatal care and exhibited good postnatal adaptation. Mother and child were discharged in good health.

[Management of cervical cancer during pregnancy: report of 05 cases]

L'association d'un cancer du col utérin avec une grossesse est une éventualité rare. Son incidence est assez mal évaluée, elle se situe selon les études entre 1 et 2/10 000. Lorsque la découverte en est faite, il faut conjuguer deux impératifs parfois totalement divergents: le traitement de la mère et la prise en charge du foetus. Cette association pose schématiquement quatre grands problèmes, qui sont: Celui du diagnostic, qui est loin d’être évident, compte tenu des remaniements cervicaux observés en début de gestation, le pronostic de l'affection, la date du traitement chirurgical et du délai entre le diagnostic et la prise en charge thérapeutique, enfin et de manière plus accessoire, le devenir de la grossesse et le mode d'accouchement. Nous rapportons une série de 5 cas de cancer du col utérin découverts au cours de la grossesse colligés dans notre service entre 2010 et 2013. La prise en charge thérapeutique est identique à celle des patientes en dehors de la grossesse même si quelques adaptations sont nécessaires du fait de l’état gravide, le pronostic du cancer ne semble pas être modifié par la grossesse.

Gynaecological cancers in pregnancy

Cervical and ovarian cancers are the most common gynaecological cancers diagnosed during pregnancy. In early-stage cervical cancer during the first and at the beginning of the second trimester, the two main considerations for management of the patient are the tumour size (and stage) and nodal staging. MRI and laparoscopic lymphadenectomy are useful for clinicians planning a potentially conservative approach. The management of patients with locally advanced cervical disease is controversial and should be discussed on a case-by-case basis according to the tumour size, radiological findings, the term of pregnancy, and the patient's wishes. Different histological types of malignant ovarian diseases arise during pregnancy and their management depends on the diagnosis (histological subtypes, tumour differentiation, and nodal status), the tumour stage, and the trimester of the pregnancy. In patients with peritoneal spread or high-risk early-stage disease, neoadjuvant chemotherapy with pregnancy preservation could be appropriate.

Addressing concerns about cisplatin application during pregnancy

INTRODUCTION

Cervical cancer in second trimester of pregnancy is an oncologic challenge. Cisplatin is recommended to prevent cancer progression. This is a series correlating in vivo cisplatin concentration in the fetomaternal compartment and in breast milk with child development.

METHODS

Eight consecutive patients with cervical cancer diagnosed during the second trimester underwent conization/biopsy and/or pelvic laparoscopic lymphadenectomy (LAE). Delay of pregnancy in combination with neoadjuvant monochemotherapy was performed. After 2-4 cycles of cisplatin monochemotherapy cesarean section followed by radical hysterectomy was performed above 31 weeks of gestation. Synchronous samples from maternal blood, umbilical cord blood, and amniotic fluid were taken and analyzed. A probe of breast milk was taken from three patients. Pediatric aftercare was done every three months postpartum.

RESULTS

Laparoscopic LAE was uncomplicated in all patients. In seven out of eight patients lymph nodes were tumor free. Nine healthy babies were delivered. Pediatric follow-up showed normal development. Cisplatin concentrations in the umbilical cord and amniotic fluid were 31-65% and 13-42% of the amount in maternal blood, respectively. In breast milk, cisplatin was detectable in 1-10% of maternal blood concentration.

CONCLUSION

Knowledge of significant lower cisplatin concentrations in fetal compartment and normal child growth provides additional security to apply cisplatin in pregnancy. Breastfeeding cannot be recommended.

French recommendations on the management of invasive cervical cancer during pregnancy

BACKGROUND

Cervical cancer is one of the most frequently diagnosed cancers during pregnancy, but the management of such cases remains unclear. A Working Group was set up in 2007 in France to propose national recommendations for the management of pregnant patients with invasive cervical carcinoma.

METHODS

The recommendations are based on this literature review conducted by the members of the Working Group.

RESULTS

Management of cervical cancer during pregnancy depends on 5 factors: stage of the disease (and the tumor size), nodal status, histological subtype of the tumor, term of the pregnancy, and whether the patient wishes to continue her pregnancy. In patients with early-stage disease diagnosed during the first 2 trimesters of pregnancy, there is an increasing tendency to preserve the pregnancy while awaiting fetal maturity in patients with absence of nodal involvement. The delivery (when the fetal maturity is attained) should be then performed using a cesarean section.

CONCLUSIONS

This article proposes recommendations for the management of pregnant patients with invasive cervical cancer. These recommendations have been validated by the 3 main scientific societies of gynecologic oncology, pelvic surgery, and obstetrics and gynecology in France.

Gynecologic cancers in pregnancy: guidelines of an international consensus meeting

BACKGROUND

Gynecologic cancer during pregnancy is a special challenge because cancer or its treatment may affect not only the pregnant women in general but directly involve the reproductive tract and fetus. Currently, there are no guidelines on how to deal with this special coincidence.

METHODS

An international consensus meeting on staging and treatment of gynecological malignancies during pregnancy was organised including a systematic literature search, and interpretation followed by a physical meeting of all participants with intensive discussion. In the absence of large trials and randomized studies, recommendations were based on available literature data and personal experience thus representing a low but best achievable level of evidence.

FINDINGS

Randomized trials and prospective studies on cancer treatment during pregnancy are lacking. Gynecological cancer during pregnancy is a demanding problem, and multidisciplinary expertise should be available. Counseling both parents on the maternal prognosis and fetal risk is needed. When there is a firm desire to continue the pregnancy, gynecological cancer can be treated in selected cases. The staging and treatment should follow the standard approach as much as possible. Guidelines for safe pelvic surgery during pregnancy are presented. Mainly in cervical and ovarian cancer, chemotherapy and an alternative surgical approach need to be considered. Administration of chemotherapy during the second or third trimester may probably not increase the incidence of congenital malformations. Until now, the long-term outcome of children in utero exposed to oncological treatment modalities is poorly documented, but preterm birth on its own is associated with cognitive impairment. Delivery should be postponed preferably until after a gestational age of 35 weeks.

INTERPRETATION

Further research including international registries for gynecologic cancer in pregnancy is urgently needed. The gathering of both available literature and personal experience allowed only suggesting models for treatment of gynecologic cancer in pregnancy.
