Chemoradiation therapy in pregnant patients treated for advanced-stage cervical carcinoma during the first trimester of pregnancy: report of two cases

Cervical Cancer Associated with Pregnancy: Current Challenges and Future Strategies

Cancer during pregnancy is defined as a tumor diagnosed in a pregnant woman or up to 1-year post-partum. While being a rare disease, cervical cancer is probably one of the most challenging medical conditions, with the dual stake of treating the cancer without compromising its chances for cure, while preserving the pregnancy and the health of the fetus and child. To date, guidelines for gynecological cancers are provided through international consensus meetings with expert panels, giving insights on both diagnosis, treatment, and obstetrical care. However, these expert guidelines do not discuss the various approaches than can be found within the literature, such as alternative staging modalities or innovative surgical approaches. Also, the obstetrical care of women diagnosed with cervical cancer during pregnancy requires specific considerations that are not provided within our current standard of care. This systematic review aims to fill the gap on current issues with regards to the management of cervical cancer during pregnancy and provide future directions within this evolving landscape.

Multidisciplinary Management of Cancer During Pregnancy

Cancer during pregnancy is relatively rare but is increasing in frequency in countries in which the maternal child-bearing age continues to rise. The complexities of medical decision making are underscored by the need to weigh the potential benefits of any intervention for the mother against the risks to the fetus. A majority of diagnostic evaluations can be performed safely in the setting of pregnancy and should not be delayed. Noninvasive prenatal testing that shows discordance with fetal karyotype can be a clue to an underlying maternal malignancy. After diagnosis, a multidisciplinary team should formulate a care plan for both the mother and the fetus. Key topics for discussion should include the mother's prognosis, standard treatment plan, and predictions of how modifications for a continuing pregnancy will affect the treatment plan and overall prognosis. In the context of this knowledge, frank discussions about pregnancy termination should be addressed with the patient, if appropriate. Selection of a plan for oncologic management in the case of a pregnant woman is based on the type of cancer, the tumor biology, and the tumor stage. Additional complexities for pregnant patients are typically related to the gestational age of the fetus, the dynamic physiologic changes of pregnancy, and the limited safety data for administration of most anticancer therapies during pregnancy. In this article, we summarize data related to different classes of anticancer therapies as well as considerations for the management of selected cancers. Finally, we provide some key principles that should be considered in the management of patients with cancer during pregnancy.

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.

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.

Cervical cancer screening in pregnancy

Cervical cancer is the most commonly diagnosed malignancy during pregnancy with an incidence of 1.5 to 12 per 100,000 pregnancies. In the United States between 2% and 7% of all pregnant women will have an abnormal Pap test. The management of these abnormal results during pregnancy can present a challenge to the practitioner. This article reviews recently published guidelines and current evidence for evaluation and management of abnormal cervical cytology and cervical cancer in pregnancy.

Neo-adjuvant chemotherapy for cervical cancer in pregnancy: a case report and literature review

Managing women who are pregnant and with a diagnosis of cervical cancer has many complex challenges. This case report describes the diagnosis and management of a patient presenting in her first trimester with stage 2B cervical cancer. In conjunction with this a literature review was undertaken using the following databases from the years 1970-2010: Embase, CINAHL, Medline and DARE. We examined the number of cases reported in the literature in which chemotherapy also was used in pregnant women with a cervical malignancy. Twenty-four papers were retrieved describing in total (including the present case) 35 cases of cervical cancer in pregnancy treated with this modality. Cisplatin therapy would seem the most reliable form of treatment, permitting a good outcome for most patients. The effect of delaying radiotherapy to permit pregnancy to fetal viability in larger tumours cannot be elucidated.

Neoadjuvant Chemotherapy Followed by Cesarean Radical Hysterectomy in a Triplet Pregnancy Complicated by Clear Cell Carcinoma of the Cervix: A Case Presentation and Literature Review

Objective

To report a triplet pregnancy complicated by clear cell cervical carcinoma that was managed using neoadjuvant chemotherapy followed by caesarean radical hysterectomy.

Patient History

A 26-year-old woman had a diagnosis of cervical clear cell carcinoma, which was International Federation of Gynecology and Obstetrics stage IB1, at 18 weeks of gestation during a triplet pregnancy. Owing to the patient’s strong desire for full-term pregnancy, 3 cycles of neoadjuvant chemotherapy was administered after magnetic resonance imaging evaluation of the tumor. The patient underwent cesarean delivery and radical hysterectomy at gestational week 32. The hysterectomy specimen revealed stage IB1 clear cell adenocarcinoma of the cervix. The neonates and the mother did not have any complications related to the treatment during 36 months of follow-up.

Conclusion

To the best of our knowledge, this is the first report of a triplet pregnancy complicated by cervical clear cell carcinoma that was successfully treated with neoadjuvant chemotherapy and cesarean radical hysterectomy. Our experience and literature review suggest that neoadjuvant chemotherapy for cervical carcinoma diagnosed during pregnancy is associated with excellent oncologic and fetal outcome; therefore, it may be considered as a temporary fertility-sparing approach in selected patients with a strong desire for full-term pregnancy. Nonetheless, additional research and long-term follow-up are needed to reach a more definitive conclusion.

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.

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.

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.
