Chemotherapeutic treatment of a pregnant patient with ovarian dysgerminoma

Ovarian cancer in pregnancy

OBJECTIVE

The objective of this manuscript is to review the epidemiology, diagnosis, treatment and outcomes of ovarian cancers diagnosed during pregnancy.

FINDING

Ovarian cancer in pregnancy, although rare, is more likely to be diagnosed early during pregnancy due to the increased use of high resolution ultrasound. Treatment will depend on a multidisciplinary team. These cancers are usually treated with surgery alone during pregnancy, optimally between 13-20 weeks to reduce the risk of miscarriage or preterm labor. Chemotherapy is usually given after delivery if appropriate to the tumor type, unless the patient has widely metastatic disease.

CONCLUSION

The majority of ovarian cancers diagnosed during pregnancy are Stage I due to both young age and increased use of early ultrasound during pregnancy and have a better overall prognosis than the cancers detected in older women.

The Safety of Chemotherapy for Ovarian Malignancy during Pregnancy

BACKGROUND

Data on epidemiologic features, treatments and outcomes in women diagnosed with ovarian malignancy during pregnancy are very sparse due to its low incidence. The goal of our study was to summarize the epidemiologic characteristics of pregnant women complicated with ovarian malignancy and investigate the safety and efficacy of chemotherapy during pregnancy.

METHODS

We retrospectively analyzed the clinicopathological data of eight patients suffering from ovarian malignancy during pregnancy in our institution from June 2011 to July 2021. Furthermore, a systematic literature search was conducted in PubMed up to 1 September 2021, which identified 92 cases with ovarian malignancy during pregnancy eligible for the analysis. Therefore, we collected the data of 100 pregnant patients complicated with ovarian malignancy, including clinical demographics, tumor characteristics, treatment interventions and outcomes.

RESULTS

In total, 100 pregnant patients complicated with ovarian malignancy were investigated and classified into three groups: 34 cases in the epithelial ovarian cancer (EOC) group, 38 cases in the germ cell tumors (GCTs) group and 28 cases in the sex cord-stromal tumors (SCSTs) group. The onset age of pregnant patients with epithelial ovarian cancer was significantly higher than that of other patients. Pelvic mass and abdominal pain were the common clinical presentations of pregnant patients with ovarian malignancy. For distinguishing epithelial ovarian cancer during pregnancy, the area under the curve (AUC) of CA-125 was 0.718 with an optimal cutoff value of 58.2 U/mL. Moreover, 53 patients underwent surgery during pregnancy, the majority of whom underwent unilateral adnexectomy in the second trimester. Furthermore, 43 patients received chemotherapy during pregnancy, and 28 delivered completely healthy newborns at birth; 13 neonates showed transient abnormalities without further complications; and 2 died during the neonatal period.

CONCLUSIONS

Our study reveals the safety of chemotherapy for ovarian malignancy during pregnancy. However, large-sample prospective studies are still needed to further explore the safety of chemotherapy in pregnant patients with malignancy to choose the appropriate chemotherapy regimen and achieve the maximum benefit for patients.

Efficacy and Safety of Platinum-Based Chemotherapy for Ovarian Cancer During Pregnancy: A Systematic Review and Meta-Analysis

Introduction

Based on the available data on ovarian cancer during pregnancy, we performed a review and meta-analysis to evaluate the efficacy and safety of platinum-based chemotherapy against ovarian cancer during pregnancy.

Methods

We systematically searched three databases including the PubMed, Embase, and Cochrane Library databases for articles published from January 1986 to December 2020 using the following terms: “ovarian tumors OR ovarian carcinoma OR adnexal masses OR ovarian cancer” AND “pregnancy” AND “chemotherapy.” Two authors (Yaping Pei and Yuanfeng Gou) independently searched the literature and extracted data from each eligible study. The outcome measures were overall survival (OS) and progression-free survival (PFS). The OS and PFS of all patients were estimated by Kaplan–Meier survival curves and log-rank tests.

Results

A total of 43 studies including 55 cases of ovarian cancer during pregnancy were selected. Forty-eight patients were comprehensively staged using the International Federation of Gynecology and Obstetrics (FIGO) staging system. Twenty-six of the 48 patients (54.17%) were diagnosed with early-stage disease, while the remaining had advanced stages (II, III, and IV). The mean age at diagnosis was 29.31 years. The majority of patients in this meta-analysis were diagnosed at a mean gestational age of 16.05 weeks. The mean GA at chemotherapy administration was 17.42 weeks. Overall, 55 women gave birth to 56 newborns, including a pair of twins. At the end of follow-up (median 10 months, range 0–73 months), all the children were healthy, except for one child who died 5 days after delivery due to a congenital abnormality. During 2–204 months of follow-up, there were five cases of recurrence, with no evidence of recurrence in the remaining cases. Unfortunately, one patient died 29 months after diagnosis. Neither median overall survival nor median progression-free survival was obtained.

Conclusion

Platinum-based chemotherapy may be a good choice for pregnant women with ovarian cancer who want to continue their pregnancy.

Chemotherapy for ovarian cancer during pregnancy: A systematic review and meta-analysis of case reports and series

AIM

This study aims to investigate the safety and efficacy of chemotherapy in ovarian cancer patients in pregnancy.

METHODS

In this study, eligible studies were searched on PubMed, Embase, and Cochrane Library databases up to December 31, 2020. Data were calculated and presented by frequency and percentage, mean ± standard deviation (SD), and median (range), respectively. Kaplan-Meier survival analysis was performed to estimate overall survival (OS) and progression-free survival (PFS).

RESULTS

Finally, 34 studies including 40 ovarian cancer cases receiving chemotherapy during pregnancy were included. All 40 patients received chemotherapy during pregnancy. During the follow-up, seven of 37 (18.9%) women had a relapse and four of them (4/7, 57.1%) died of recurrence. Survival analysis failed to reach median OS and PFS within the follow-up (range 3-72 months). Better OS and PFS after chemotherapy in pregnancy were obtained in women with early-stage ovarian cancer (I) compared with those with advanced stage (III-IV). Neither OS nor FS differed between women treated with multi-drugs and those with monotherapy. Forty-one newborns were delivered from 40 pregnant women. Thirty-four (34/41, 82.9%) were completely healthy at birth and the end of follow-up (range 0.18-160 months). However, one newborn died 5 days after birth due to multiple congenital malformations, and another one developed Tourette's syndrome, aphasia, Asperger's syndrome as well as speech delay.

CONCLUSIONS

This meta-analysis first reveals the efficacy and safety of chemotherapy for ovarian cancer during pregnancy, especially for early-stage patients. Cisplatin or carboplatin is suggested to be used as monotherapy to reduce adverse effects.

Pregnancy with giant ovarian dysgerminoma: A case report and literature review

RATIONALE

Dysgerminoma is an extraordinarily rare neoplasm arising from the malignant germ cells of the ovary. Early antenatal diagnosis and proper management of the neoplasm to improve maternal-neonatal results are the considerable challenges facing the gyne-oncologist. We summarize the clinical features and discuss treatment strategies of the ovary dysgerminoma (OD). Besides, we also review the literature on OD in PubMed, Web of Science Core Collection, Library of Congress, and LISTA from 1939 to 2019 to evaluate its clinical characteristics, feto-maternal compromise, management, and fertility outcome.

PATIENT CONCERNS

A 25-year-old pregnant woman reported lower abdominal pain and vomiting.

DIAGNOSIS

The patient was diagnosed as right OD.

INTERVENTIONS

She received a cesarean section due to severe abdominal pain, delivered a healthy girl at 38 C 4 weeks of gestation, and accepted fertility-preserving surgery. However, the patient refused chemotherapy postoperatively.

OUTCOMES

The patient was followed up 42 days, 3 months, and 6 months after surgery, and no tumor recurrence was observed.

LESSONS

OD has non-specificity characteristics, including age, symptoms, image date, and tumor marks. However, these abnormal indicators may provide some evidence for accurate antenatal diagnosis. The management strategies should be considered comprehensively on an individual basis, and fertility-preserving surgery should be carried out in the second trimester if further pregnancy is desired. Adjuvant chemotherapy needs to be applied to the treatment of OD patients with The International Federation of Gynecology and Obstetrics (FIGO) stages II, III, and IV and timely chemotherapy is suggested if there are several weeks before the expected date of delivery. The overall prognosis of OD patients is excellent.

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.

A review on pregnancy complicated by ovarian epithelial and non-epithelial malignant tumors: Diagnostic and therapeutic perspectives

The management of gestational ovarian cancer can be challenging because of the risk of fetal wastage, and the possibility of treatment-related complications to the fetus; it is based on insufficient data from retrospective studies and case series. Here, a literature review of the diagnostic and surgical approaches to the gestational ovarian cancer has been performed; moreover, data on safety of chemotherapeutic treatments in pregnancy, including both oncologic and fetal outcomes, have also been reviewed. Up to now, 193 cases of ovarian cancers during pregnancy have been reported in the English literature. Treatment of ovarian malignancies during pregnancy depends on histology, stage, and gestational weeks. When possible, surgical excision is indicated, and fertility-sparing surgery can be offered to stage I epithelial ovarian tumours (EOC), germ cell ovarian, or sex-cord stromal ovarian tumours. Neoadjuvant and/or adjuvant chemotherapy for advanced ovarian tumours is indicated as in non-pregnant women. Administration of chemotherapy after the first trimester, can cause fetal growth restriction, while being seemingly safe. The therapeutic approach of ovarian cancer in pregnancy should be individualized and intended in specialized centers.

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.

Ovarian Cancer During Pregnancy: A Case Report and Literature Review

Ovarian cancer during pregnancy is a rare event. Little is known about the treatment of this condition due to lack of prospective randomized trials and cohort studies. In this paper the authors reported a rare case of small cells ovarian cancer, diagnosed at 16 weeks of gestation, treated with conservative surgery at 18 weeks and chemotherapy. At week 38, the patient underwent caesarean section and delivered a healthy baby girl. Staging surgery was then carried out followed by adjuvant chemotherapy. Thus the findings from this case concluded that prognosis and quality of the patient’s life should be a priority, chemotherapy during the second trimester seems to be safe however, potential risks of this interventions still has to be considered.

Maternal and fetal outcomes of taxane chemotherapy in breast and ovarian cancer during pregnancy: case series and review of the literature

BACKGROUND

The purpose of this study was to evaluate the use of taxane chemotherapy during pregnancy and compare maternal and neonatal outcomes with those in women who did not receive taxanes during pregnancy, and review current existing data.

STUDY DESIGN

This is a retrospective cohort study in which women were identified from the Cancer and Pregnancy Registry at Robert Wood Johnson Medical Center. A retrospective chart analysis and an independent t-test were carried out comparing patient outcomes. A literature search in Ovid, Medline and PubMed was then carried out using the terms 'breast or ovarian cancer', 'pregnancy', 'paclitaxel', 'docetaxel', 'taxanes' and 'chemotherapy'.

RESULTS

Twelve of 129 women with breast cancer were exposed to taxanes during pregnancy. Three of nine women with ovarian cancer received taxane-based treatment during pregnancy. Birth weight, gestational age at delivery, rate of growth restriction, congenital anomalies and incidence of maternal and neonatal neutropenia were not statistically different between the two groups.

CONCLUSIONS

Taxane-based chemotherapy does not appear to increase the risk of fetal or maternal complications when compared with conventional chemotherapy in the small cohort of women in our Registry.

Taxanes for ovarian cancer during pregnancy: a systematic review

OBJECTIVE

Ovarian cancer in pregnancy is uncommon; however, this diagnosis adds complexity to cancer treatment recommendations. This is the first systematic review to synthesize all available data and evaluate the efficacy and safety of taxanes during pregnancy in ovarian cancer.

METHODS

This systematic review was performed in accordance with PRISMA guidelines. All studies that examined the efficacy and safety of taxanes administered during pregnancy in ovarian cancer, regardless of sample size, were considered eligible.

RESULTS

Overall, 8 articles (11 pregnancies, 12 newborns) were retrieved for paclitaxel and 1 for docetaxel (1 pregnancy, 1 newborn). In 92.31% of cases a healthy child was born, with a median follow-up of 20 months. The mean weight of the babies at delivery was 2,381 g. One study providing follow-up until the 11th year of age reported a case of attention deficit disorder. In 6 out of 8 case reports providing survival data, the mother was alive and disease free at the end of follow-up (ranging from 9.75 to 45 months).

CONCLUSION

Taxanes may play a significant role in the treatment of ovarian cancer patients during the 2nd and 3rd trimesters. Before that, the risk of abortion or congenital anomalies is increased.

Mediastinal dysgerminoma complicating pregnancy

Malignancy complicating pregnancy represents one of the most challenging clinical situations. Lack of evidence and the presence of the dependent fetus contribute to the management dilemma. A 26-year-old primigravida presented at 23 weeks of gestation with a bulging substernal mass. Fine-needle aspiration was reported as mediastinal dysgerminoma. She was treated with weekly bleomycin and three weekly cisplatin and etoposide (BEP). Maternal neutropenia after 11 weeks of bleomycin required colony stimulator factor. Fetal growth restriction necessitated delivery at 31 weeks. Significant clinical and radiological tumour regression was noted after chemotherapy. Postnatally mother received external beam radiotherapy but the disease worsened two weeks after the completion of radiotherapy. Mediastinal dysgerminoma differs from the ovarian counterpart and therefore therapeutic success reports on ovarian germ cell tumours complicating pregnancy cannot be extrapolated. The safety of the BEP regimen for the fetus is yet to be established.

Paclitaxel and cisplatin chemotherapy for ovarian cancer during pregnancy: case report and review of the literature

The safety of chemotherapy during pregnancy is debatable. We present a case of advanced ovarian cancer, diagnosed at week 28 of gestational age, treated with 2 cycles of paclitaxel/cisplatin (TC) chemotherapy during pregnancy, with no serious toxicity. At week 34, the patient underwent a caesarean section and delivered a healthy girl. Four additional cycles of TC were administered. Three months after completing chemotherapy, the patient developed abdominal progression and subsequently a huge metastatic cystic mass in the brain. Despite subsequent therapies, the patient died of progressive disease 35 months after the diagnosis. The infant had normal growth and development by 73 months of her age. This is another reported case of ovarian cancer diagnosed during the second trimester of the pregnancy treated with TC chemotherapy without apparent teratogenic effect.

Treatment of recurrent vulvar Paget disease with imiquimod cream: a case report and review of the literature

INTRODUCTION

Extra-mammary Paget disease is one of the rare neoplastic conditions of the skin. The most common site of involvement is the vulva and presents itself with erythematous plaques. Surgery is the most important treatment option. In the recent years, there are publications of the topical use of imiquimod cream in extra-mammary cutaneous Paget disease. We report the case of a woman with recurrent vulvar Paget disease, who underwent successful treatment with imiquimod cream. We also review the reports of other patients with vulvar Paget disease who were treated with topical imiquimod cream.

CASE REPORT

A 65-year-old woman presented to the Oncology Outpatient Clinic with an itchy lesion in her vulva for 2 years. In the gynecologic examination, a hyperkeratotic erythematous lesion was found starting from the right labium to involve clitoris, with a size of 4 × 3 cm. Pathology result was reported as Paget disease. She was operated and wide vulvar excision was performed with a safety margin of 2 cm. Then recurrence two times occurred. Because she refused surgery, imiquimod cream 5% was applied for treatment.

CONCLUSION

Imiquimod cream is an effective and safe therapeutic agent for both primary and recurring vulvar Paget disease.

Treatment of the pregnant mother with cancer: a systematic review on the use of cytotoxic, endocrine, targeted agents and immunotherapy during pregnancy. Part I: Solid tumors

The association of cancer and pregnancy is increasingly encountered nowadays in clinical practice. Due to the relative rarity of the situation, it lacks a systematized approach. Different systemic therapies are used in managing cancer with uncertainty regarding the potential hazards they could pose on the pregnancy and/or the fetus. We have performed a systematic review of literature to identify all reports addressing cancer patients who were exposed to any of the known systemic therapies during the course of the pregnancy. The results were discussed in two parts; part I addresses pregnant patients with solid tumors while part I for those with hematological malignancies. In part I, we identified different solid tumors diagnosed and treated during the course of pregnancy. Breast cancer was the most commonly treated followed by ovarian cancer. Other tumors were treated as well including lung cancer, cervical cancer, sarcoma and melanomas. It is important to acknowledge the intent of therapy (palliative vs. curative) and the patients has to be properly counseled to reach an informed decision. We aim to provide a more robust consensus on how to approach these cases and provide a higher degree of evidence to support the safety of applying certain management strategies over the other.

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.
