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

Middle cerebral artery peak systolic velocity monitoring of fetal anemia during chemotherapy in pregnancy

INTRODUCTION

Chemotherapy during pregnancy can increase the risk of fetal anemia. Severe fetal anemia can lead to the development of hydrops fetalis and potentially fetal demise. Hence, it is imperative to implement consistent monitoring methods in the context of chemotherapy treatment. This study aimed to diagnose and monitor fetal anemia using middle cerebral artery peak systolic velocity (MCA-PSV) as a diagnostic tool during chemotherapy in pregnant women.

MATERIAL AND METHODS

The study employed a prospective analysis involving a case series of 15 patients diagnosed with cancer during pregnancy and subsequently underwent chemotherapy. MCA-PSV was used to identify fetal anemia. The patients were scheduled for ultrasound examinations of the MCA-PSV. The first examination was performed on the same day as the administration of chemotherapy, while the second occurred on the 10th day after chemotherapy. The measurement technique used in the study was based on the methodology proposed by Mari and Barr. The multiples of the median were calculated using the calculators provided by Medicina Fetal Barcelona. Based on these values anemia severity was determined. When moderate or severe anemia was identified, chemotherapy was individually modified. Additionally, a blood count analysis was conducted immediately after the delivery of the newborn.

RESULTS

Five patients were diagnosed with fetal or newborn anemia. With MCA-PSV, we identified moderate fetal anemia in two patients and severe fetal anemia in one. The complete blood count testing of newborns revealed mild anemia in three patients. One case was unrelated to chemotherapy-induced anemia. During treatment, fetal anemia did not corelate with maternal anemia.

CONCLUSIONS

In four cases of anemia the combination of cisplatin and iphosphamide was used as a chemotherapy agent. No anemia was observed in other drug combinations. Our findings suggest that MCA-PSV is a reliable method for identifying anemia and should be included in the treatment protocol for chemotherapy-induced fetal anemia.

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.

Evaluating offspring Genomic and Epigenomic alterations after prenatal exposure to Cancer treatment In Pregnancy (GE-CIP): a multicentric observational study

INTRODUCTION

Around 1 in 1000-2000 pregnancies are affected by a cancer diagnosis. Previous studies have shown that chemotherapy during pregnancy has reassuring cognitive and cardiac neonatal outcomes, and hence has been proposed as standard of care. However, although these children perform within normal ranges for their age, subtle differences have been identified. Given that chemotherapeutic compounds can cross the placenta, the possibility that prenatal chemotherapy exposure mutates the offspring's genome and/or epigenome, with potential deleterious effects later in life, urges to be investigated.

METHODS AND ANALYSES

This multicentric observational study aims to collect cord blood, meconium and neonatal buccal cells at birth, as well as peripheral blood, buccal cells and urine from infants when 6, 18 and/or 36 months of age. Using bulk and single-cell approaches, we will compare samples from chemotherapy-treated pregnant patients with cancer, pregnant patients with cancer not treated with chemotherapy and healthy pregnant women. Potential chemotherapy-related newborn genomic and/or epigenomic alterations, such as single nucleotide variants, copy number variants and DNA-methylation alterations, will be identified in mononuclear and epithelial cells, isolated from blood, buccal swabs and urine. DNA from maternal peripheral blood and paternal buccal cells will be used to determine de novo somatic mutations in the neonatal blood and epithelial cells. Additionally, the accumulated exposure of the fetus, and biological effective dose of alkylating agents, will be assessed in meconium and cord blood via mass spectrometry approaches.

ETHICS AND DISSEMINATION

The Ethics Committee Research of UZ/KU Leuven (EC Research) and the Medical Ethical Review Committee of University Medical Center Amsterdam have approved the study. Results of this study will be disseminated via presentations at (inter)national conferences, through peer-reviewed, open-access publications, via social media platforms aimed to inform patients and healthcare workers, and through the website of the International Network on Cancer, Infertility and Pregnancy (www.cancerinpregnancy.org).

A case of neoadjuvant chemotherapy in pregnancy with cervical cancer (IB3)

Compared with the early symptoms of non-pregnancy, the early pregnancy with cervical cancer is often confused with threatened abortion, so it is difficult to diagnose and delay the time of treatment. At present, compared with cervical cancer, there is no clear and standard treatment for cervical cancer in pregnancy. At present, the diagnosis and treatment plan is mainly made according to the pathological examination, staging, fetal development (whether there is abnormality on ultrasound and whether the chromosome karyotype is normal or not) and the pregnant women and their family members' pregnancy wishes. A case of pregnancy complicated with cervical cancer who was terminated by planned cesarean section after neoadjuvant chemotherapy (NACT) with irregular vaginal bleeding as the first symptom was analyzed retrospectively.

Clinical and Management Dilemmas Concerning Early-Stage Cervical Cancer in Pregnancy - A Case Report

Background

Cervical cancer in pregnancy is rare and its management remains a formidable challenge. Clinical upstaging is a serious concern. Presentation may mimic pregnancy-related conditions, thus delaying diagnosis and leading to an advanced stage at presentation. In addition, concerns regarding chemotherapy safety in pregnancy may hinder its administration. Definitive therapy may also be delayed due to pregnancy.

Case Report

A 37-year-old G3P2A0 10-11 weeks pregnant woman was diagnosed with stage IB2 cervical cancer. We originally planned to perform neoadjuvant chemotherapy with paclitaxel 175mg/m2 and carboplatin 6 AUC every 21 days followed by caesarean section and radical hysterectomy. However, preoperatively, the tumor had grown further and progressed to stage IIB. Postpartum radiotherapy was thus indicated. Lower segmental caesarean section along with bilateral salpingectomy and ovarian transposition were performed. Radiotherapy was administered through external beam radiation therapy and brachytherapy. The patient delivered a small for gestational age male baby with no abnormalities. At 2-month follow-up, the infant appeared generally healthy.

Conclusion

Cancer diagnosis during pregnancy adversely impacts women's physical and psychological states. Symptoms may mimic pregnancy-related conditions, thus delaying diagnosis. Its management involves a multidisciplinary team to protect both maternal and fetal health.

Cervical cancer in the pregnant population

Cervical cancer is the second most encountered cancer in pregnant patients. The 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system for cervical cancer updated the staging of primary cervical carcinoma and disease process, with formal incorporation of imaging as a vital source of information in the management process to improve accuracy. Diagnosis and treatment of the pregnant population is a complex interplay of achieving adequate diagnostic information and optimal treatment while minimizing toxicity and risks to the mother and fetus. While novel imaging techniques and anticancer therapies are rapidly developed, much information on the safety and feasibility of different therapies is not yet available in the pregnant population. Therefore, managing pregnant patients with cervical cancer is complex and requires a multidisciplinary approach.

The effect of preserving pregnancy in cervical cancer diagnosed during pregnancy: a retrospective study

Objective

Cervical cancer diagnosed during pregnancy is a rare event, and data regarding efficacy of cancer treatment during pregnancy is limited. This study aimed to assess the safety of continuation of the pregnancy for mother and fetus when concomitantly diagnosed with cervical cancer.

Methods

This study retrospectively analyzed all cervical cancer patients diagnosed while pregnant or immediately postpartum, inclusive from Jan 2010 to June 2019 at our institute. Patient clinical details and follow-up were obtained from hospital records.

Results

The study comprised 40 patients with clinical cancer stages of IA1 (1/40, 2.5%); IB1 (15/40, 37.5%); IB2 (10/40, 25%); IIA (12/40, 30%); and IIB (2/40, 5%). There were 38 patients diagnosed during pregnancy, and 2 diagnosed in the postpartum period. Of the 38 patients, 17 were diagnosed in the first trimester, 13 in the second trimester, and 8 in the third trimester. 10 of 38 patients (26.3%) continued their pregnancy after learning of their diagnosis; 7 (70%) in the third trimester and 3 (30%) in the second trimester. The mean time from diagnosis to surgery in the patients who continued their pregnancy was 52.7 days, which was statistically significantly greater than the termination of pregnancy group (52.7 vs. 16.3 days, P < 0.01). Notably, there was no survival difference between the 2 groups (100% vs. 90.91%, P = 0.54), and none of the pregnant women who ultimately died had delayed treatment due to pregnancy. Similarly, the surgical estimated blood loss and operative duration comparison in the 2 groups were not significantly different.

Conclusions

In the present study, the gestational age of pregnancy at the time of initial diagnosis of cervical cancer was an important determinant in the disease management. Continuation of the pregnancy when diagnosed with cervical cancer may not affect the oncologic outcome of the mother nor increase either surgical or obstetric complications. Additionally, the use of neoadjuvant chemotherapy did not threaten the health of the fetus. These results may be useful in counseling patients facing the diagnosis of cervical cancer during pregnancy.

Weekly Paclitaxel Administered During a Twin Pregnancy for Recurrent Breast Cancer: Case Report and Review of the Literature

Although cancer treatment during single pregnancy has been standardized, how to manage cancer diagnosed during a multiple gestation is still unclear. Chemotherapy during pregnancy has shown to be safe, however, there are reports of increased risks of fetal complications such as intrauterine growth restriction and preterm birth. Also, how to best adjust this to the pharmacokinetic characteristics of a twin gestation has yet to be fully investigated. We report the case of an IVF twin pregnancy with a diagnosis of breast cancer recurrence shortly after conception, and how the pregnancy was managed to obtain optimal obstetric, maternal/oncological, and fetal outcomes.

Neoadjuvant Chemotherapy in Pregnant Patients with Cervical Cancer: A Monocentric Retrospective Study

Background: To date, little and discordant data still exists on the management of cervical cancer (CC) during pregnancy. In this paper, we report our experience of the treatment of these patients analyzing the oncologic, obstetric, and neonatal outcomes. Methods: Between January 2010 and December 2021, 13 patients were diagnosed with CC during pregnancy. All patients underwent platinum-based neoadjuvant chemotherapy (NACT) and 11/13 patients underwent a cesarean radical hysterectomy (CRH). Results: All 13 patients were diagnosed with squamous-cell carcinoma, FIGO-2018 stage between IB2-IIIC1. The majority of patients had a partial (61.5%) or complete (15.4%) response to NACT. Most patients had a regular course of pregnancy and the obstetric complications observed were gestational diabetes mellitus in 23.1% and IUGR in 15.4% of cases. CRH was performed in the absence of major complications. Only 2 patients (15.4%) had disease recurrence and only 1 patient (7.7%) died of disease. All children are currently healthy. At birth, we observed mainly prematurity-related complications (38.5% respiratory distress syndrome and 7.7% neonatal jaundice) and only a case of congenital malformation (hypospadias). In our pediatric population, we reported a case of malignancy (acute myeloid leukemia). Conclusion: NACT seems to be safe and efficacious in controlling tumor burden during pregnancy. CRH following NACT appears to be feasible, avoiding repeated surgery and treatment delays. This approach is also reasonably safe from a maternal, obstetric, and neonatal point of view.

Small cell neuroendocrine tumour of the cervix in pregnancy: the importance of multidisciplinary management

A woman in her mid-20s presented with bleeding at 18 weeks gestation from a cervical 'polyp'. Histopathology demonstrated a rare small cell neuroendocrine of the cervix. There were only 18 cases of neuroendocrine tumours of the cervix in and around pregnancy in the literature, so the evidence base for treatment was scarce. She was treated with neoadjuvant chemotherapy, using a regimen used for small cell neuroendocrine tumours of the lung, to allow for fetal lung maturity. Disease initially responded, then progressed and she was delivered at 32 weeks by caesarean radical hysterectomy. Adjuvant treatment included further chemotherapy and radical pelvic radiotherapy. The woman and her child are doing well over 6 years after treatment, although the woman has significant side effects of both radical surgery and radiotherapy. This case emphasises the need for excellent communication between multidisciplinary professionals, patients and their families and using external colleagues to help with rare clinical problems.

Incidence of childhood hearing loss after in utero exposure to platinum agents

OBJECTIVE

When treated for childhood cancers, at least 50% of children exposed to platinum agents have permanent hearing loss. We determined the relative risk of childhood hearing loss after in utero exposure to platinum chemotherapy in our registry cohort.

METHOD

After exposure to platinum chemotherapy in utero, all children undergo routine newborn hearing screening. This consists of Otoacoustic Emissions. Children who failed this screen were evaluated by audiologists. For those children with hearing loss by Automated Auditory Brainstem Response, prenatal and postnatal treatment details were compared to platinum exposed children without hearing loss.

RESULTS

Three hundred and seven children were exposed to chemotherapy in utero. Four children were diagnosed with hearing loss, all exposed to platinum agents. Chemotherapy exposures included: Cisplatin/Paclitaxel (2), Etoposide/Cisplatin/Bleomycin (1), Carboplatin/Paclitaxel (1) to treat ovarian (2), or cervical cancer (2). Of the 39 platinum exposed without hearing loss: 11 children were exposed to oxaliplatin, 16 were exposed to cisplatin and 12 to carboplatin in utero. Two hundred and sixty four women received non-platinum based chemotherapy for various cancers during pregnancy. Among these, there were no cases of hearing loss. There was a significant difference in hearing loss based on exposure to platinum agents in utero compared to non-platinum-containing chemotherapy regimens, 4/43 versus 0/264, p = 0.0003. There were no statistical differences in prenatal and postnatal treatment details, including: gestational age at diagnosis, at first chemotherapy treatment, at first platinum treatment, at delivery (<32 weeks, <35 weeks, <37 weeks), gender, birthweight, birthweight percentile, rates of intrauterine growth restriction, neonatal complications or use of postnatal antibiotics between the platinum exposed children with and without hearing loss.

CONCLUSION

The only children in the registry exposed to chemotherapy who were diagnosed with hearing loss had been exposed to cisplatin or carboplatin in utero. No hearing loss occurred in children exposed to oxaliplatin, or non-platinum agents. Due to a concern for cisplatin ototoxicity, carboplatin is the preferred platinum agent for use in pregnancy when equivalent maternal survival can be expected for the particular cancer type. For newborns exposed to platinum agents in utero, newborn screening with an auditory emissions test at birth (OES) may not detect sensorineural hearing loss and auditory brainstem response testing is recommended, regardless of the newborn screening result.

Novel next-generation sequencing-based methodologies to characterize the mutational consequences of (prenatal) chemotherapy exposure in noncancerous tissue

PURPOSE OF REVIEW

Although chemotherapeutics are considered as genotoxins for decades, their exact mutagenic impact on the genome of cancerous and normal cells of cancer patients was unknown for a long time. However, this knowledge is necessary to understand the long-term side effects of chemotherapy. A particular condition represents pregnant cancer patients being treated with chemotherapy. Since certain chemotherapeutics can cross the placenta, concerns exist about possible mutational effects on the fetus' genome with potential long-term health consequences.

RECENT FINDINGS

Recent advances of next-generation sequencing (NGS) techniques have opened possibilities to explore the exact mutational footprint of chemotherapies in healthy tissue from treated cancer patients. However, the ultra-low frequency of chemotherapy-induced mutations, introduction of technical artefacts, and inaccessibility of normal tissue has posed important limitations. This review discusses five state-of-the-art approaches that were recently designed to overcome these drawbacks.

SUMMARY

Results of the latest investigations give valuable insights into the genome-wide genotoxicity profile of frequently applied chemotherapies, with most of these drugs being associated with a signature of random base substitutions and small indels. Though these findings still might be limited to extrapolate to healthy tissue, they pave the way for studies on the origin of long-term chemotherapy-related adverse health effects.

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.

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.

Cancer during Pregnancy: A Review of Preclinical and Clinical Transplacental Transfer of Anticancer Agents

The occurrence of cancer during pregnancy is observed in 1 in 1000 pregnancies and is expected to increase given the trend of delaying childbearing. While breast cancer is the most common, the incidence of other cancers, such as cervical, ovarian, and lung cancers as well as hemopathies and melanomas, is also increasing. Thus, cancer occurrence in pregnant women raises questions of management during pregnancy and, especially, assessment of the treatment benefit-risk ratio to ensure optimal management for the mother while ensuring the safety of the fetus. Chemotherapy remains a cornerstone of cancer management. If the use of anticancer agents appears possible during pregnancy, while avoiding the first trimester, the extent of placental transfer of different anticancer agents varies considerably thereafter. Furthermore, the significant physiological pharmacokinetic variations observed in pregnant women may have an impact on the placental transfer of anticancer agents. Given the complexity of predicting placental transfer of anticancer agents, preclinical studies are therefore mandatory. The aim of this review was to provide updated data on in vivo and ex vivo transplacental transfer of anticancer agents used in the management of the most common pregnancy-associated cancers to better manage these highly complex cases.

Neoadjuvant chemotherapy in pregnant patients with cervical cancer: a Latin-American multicenter study

OBJECTIVE

To describe oncologic and obstetric outcomes in patients diagnosed with cervical cancer during pregnancy who had a successful delivery after neoadjuvant chemotherapy.

METHODS

A multicenter retrospective review was conducted in 12 institutions from six Latin American countries, between January 2007 and December 2018. Data collected included clinical characteristics, neoadjuvant chemotherapy agents, treatment, obstetric and oncologic outcomes.

RESULTS

Thirty-three patients were included. Median age was 34 years (range 31-36). Twenty (60.6%) women were diagnosed at early stage (IB), and 13 (39.4%) with locally advanced stage (IIA-IIIB) according to FIGO 2009 classification. Carboplatin and paclitaxel was the most frequent combination used (60.6%). Partial and complete response rates were 27.3% and 9.1%, respectively. Median gestational age at delivery was 35 weeks (range 34-36). All patients had live births delivered by cesarean section. Obstetric pathology: pre-term labor, placenta percreta or intra-uterine growth restriction, was documented in seven patients (21.2%). Two (6.1%) neonates had low birth weight. Definitive treatment was primary chemo-radiation in 19 (57.6%) patients, radical hysterectomy in 11 (33.3%), abandoned radical hysterectomy with para-aortic lymphadenectomy and ovarian transposition in 1 patient (3.0%), and no further treatment in 2 (6.1%) patients. After a median follow-up of 16.3 months (range 2.0-36.9), 8 (26.7%) patients had recurrent disease. Of these, four (13.3%) died due to disease.

CONCLUSION

Neoadjuvant chemotherapy may be offered to patients wishing to preserve an ongoing pregnancy in order to achieve fetal maturity. Long-term consequences of chemotherapy in the child are yet to be determined.

Cisplatin and carboplatin result in similar gonadotoxicity in immature human testis with implications for fertility preservation in childhood cancer

BACKGROUND

Clinical studies indicate chemotherapy agents used in childhood cancer treatment regimens may impact future fertility. However, effects of individual agents on prepubertal human testis, necessary to identify later risk, have not been determined. The study aimed to investigate the impact of cisplatin, commonly used in childhood cancer, on immature (foetal and prepubertal) human testicular tissues. Comparison was made with carboplatin, which is used as an alternative to cisplatin in order to reduce toxicity in healthy tissues.

METHODS

We developed an organotypic culture system combined with xenografting to determine the effect of clinically-relevant exposure to platinum-based chemotherapeutics on human testis. Human foetal and prepubertal testicular tissues were cultured and exposed to cisplatin, carboplatin or vehicle for 24 h, followed by 24-240 h in culture or long-term xenografting. Survival, proliferation and apoptosis of prepubertal germ stem cell populations (gonocytes and spermatogonia), critical for sperm production in adulthood, were quantified.

RESULTS

Cisplatin exposure resulted in a significant reduction in the total number of germ cells (- 44%, p < 0.0001) in human foetal testis, which involved an initial loss of gonocytes followed by a significant reduction in spermatogonia. This coincided with a reduction (- 70%, p < 0.05) in germ cell proliferation. Cisplatin exposure resulted in similar effects on total germ cell number (including spermatogonial stem cells) in prepubertal human testicular tissues, demonstrating direct relevance to childhood cancer patients. Xenografting of cisplatin-exposed human foetal testicular tissue demonstrated that germ cell loss (- 42%, p < 0.01) persisted at 12 weeks. Comparison between exposures to human-relevant concentrations of cisplatin and carboplatin revealed a very similar degree of germ cell loss at 240 h post-exposure.

CONCLUSIONS

This is the first demonstration of direct effects of chemotherapy exposure on germ cell populations in human foetal and prepubertal testis, demonstrating platinum-induced loss of all germ cell populations, and similar effects of cisplatin or carboplatin. Furthermore, these experimental approaches can be used to determine the effects of established and novel cancer therapies on the developing testis that will inform fertility counselling and development of strategies to preserve fertility in children with cancer.

The impact of cancer and chemotherapy during pregnancy on child neurodevelopment: A multimodal neuroimaging analysis

BACKGROUND

This study applies multimodal MRI to investigate neurodevelopment in nine-year-old children born to cancer-complicated pregnancies.

METHODS

In this cohort study, children born after cancer-complicated pregnancies were recruited alongside 1:1 matched controls regarding age, sex and gestational age at birth (GA). Multimodal MRI was used to investigate whole-brain and subcortical volume, cortical structure (using surface-based morphometry), white matter microstructure (using fixel-based analysis) and functional connectivity (using resting-state blood-oxygen-level-dependant signal correlations). Graph theory probed whole-brain structural and functional organization. For each imaging outcome we conducted two group comparisons: 1) children born after cancer-complicated pregnancies versus matched controls, and 2) the subgroup of children with prenatal chemotherapy exposure versus matched controls. In both models, we used the covariate of GA and the group-by-GA interaction, using false-discovery-rate (FDR) or family-wise-error (FWE) correction for multiple comparisons. Exploratory post-hoc analyses investigated the relation between brain structure/function, neuropsychological outcome and maternal oncological/obstetrical history.

FINDINGS

Forty-two children born after cancer-complicated pregnancies were included in this study, with 30 prenatally exposed to chemotherapy. Brain organization and functional connectivity were not significantly different between groups. Both cancer and chemotherapy in pregnancy, as compared to matched controls, were associated with a lower travel depth, indicating less pronounced gyrification, in the left superior temporal gyrus (pFDR ≤ 006), with post-hoc analysis indicating platinum derivatives during pregnancy as a potential risk factor (p = .028). Both cancer and chemotherapy in pregnancy were related to a lower fibre cross-section (FCS) and lower fibre density and cross-section (FDC) in the posterior corpus callosum and its tapetal fibres, compared to controls. Higher FDC in the chemotherapy subgroup and higher FCS in the whole study group were observed in the anterior thalamic radiations. None of the psycho-behavioural parameters correlated significantly with any of the brain differences in the study group or chemotherapy subgroup.

INTERPRETATION

Prenatal exposure to maternal cancer and its treatment might affect local grey and white matter structure, but not functional connectivity or global organization. While platinum-based therapy was identified as a potential risk factor, this was not the case for chemotherapy in general.

FUNDING

This project has received funding from the European Union's Horizon 2020 research and innovation program (European Research council, grant no 647,047), the Foundation against cancer (Stichting tegen kanker, grant no. 2014-152) and the Research Foundation Flanders (FWO, grants no. 11B9919N, 12ZV420N).

A fight-and-flight for life: A rare case of advanced cervical cancer in pregnancy

BACKGROUND

Advanced cervical cancer during pregnancy is an extremely rare event. We describe a case of at least stage IIIB cervical squamous cell carcinoma during pregnancy. This may possibly represent the longest gestation from time of diagnosis to delivery in a case of advanced cervical cancer, with potentially the most advanced gestational age at delivery and a relatively favorable outcome in the current literature.Case: A 29-year-old female at 20 0/7 weeks of gestation with at least stage IIIB squamous cell carcinoma of the cervix flew from Micronesia to Hawaii for oncologic treatment. After consultation with gynecologic oncology and maternal-fetal medicine, she opted to continue the pregnancy and began neoadjuvant chemotherapy with carboplatin and paclitaxel. At 33 2/7 weeks of gestation, she was admitted for preterm prelabor rupture of membranes and immediately underwent a cesarean delivery for heavy vaginal bleeding. Postpartum, she underwent cisplatin chemotherapy with concurrent radiation therapy. After 6 cycles of chemotherapy, the patient's cancer had progressed to the point that hospice was recommended. She died 11 months after initial presentation.

CONCLUSION

Advanced cervical cancer during pregnancy requires individualized treatment, shared decision making, and a multidisciplinary team approach. If the pregnancy is continued, antepartum chemotherapy should be strongly considered. Maternal prognoses tend to be poor, but neonatal outcomes appear to be favorable.

A case of successful maintained pregnancy after neoadjuvant chemotherapy plus radical surgery for stage IB3 cervical cancer diagnosed at 13 weeks

Background

Cervical cancer during pregnancy is rare. The management for stage IB3 during pregnancy remains unclear and challenging. We report a successful preserved pregnancy in a stage IB3 patient who was treated with neoadjuvant chemotherapy (NACT) plus radical surgery.

Case presentation

A 36-year-old pregnant woman was diagnosed with a 5-cm-diameter stage IB3 squamous cell carcinoma of the uterine cervix at 13 gestational weeks. The patient received 5 courses of systemic chemotherapy with carboplatin and paclitaxel every 3 weeks, followed by caesarean section and radical hysterectomy. Both the mother and infant are in good general condition.

Conclusion

This case suggests that NACT plus radical surgery could be one method to maintain pregnancy in stage IB3 cervical cancer diagnosed as early as 13 gestational weeks.

Diagnosis and treatment of cervical cancer in pregnant women

In recent years, the incidence of gynecological malignant tumors during pregnancy has increased, mainly due to the increased number of old age pregnancy. The most common gynecological malignant tumors in pregnancy are cervical cancer, accounting for 71.6%, followed by ovarian malignant tumors, accounting for 7.0%. The incidence of cervical cancer in pregnancy is itself not very high, and the symptoms are easily confused with other diseases in pregnancy. During pregnancy, gynecological examination is limited, and therefore, the rate of misdiagnosis is higher. The treatment of cervical cancer during pregnancy is related to many factors, such as tumor size, pathological type, period of gestation, lymph node involvement, and patients' willingness to maintain pregnancy. As a reason of these factors, it is difficult to determine the optimal treatment. This article reviews the research progress on the diagnosis and treatment principles of cervical cancer in pregnancy, in order to strike a balance between effective treatment of tumors and protection of fetal health, and avoid delays in treatment and preterm delivery.

Cancer in Pregnancy

Cancer in pregnancy may be increasing in incidence with advancing maternal age and higher rates of obesity. The diagnosis of cancer in pregnancy provokes complex management issues balancing short- and long-term risks for both mother and baby. Every case needs to be individualized, with a multidisciplinary team of midwives, obstetricians, oncologists, surgeons, radiation oncologists, and neonatologists assisting the family to make informed decisions regarding the best treatment course for the mother and baby. The present article reviews the evidence regarding the safety of diagnostic imaging, procedures and treatment modalities for cancer for the pregnant woman and fetus. The efficacy of novel anticancer therapies highlight the need for International Registries to accumulate safety data for these agents in pregnancy as expeditiously as possible.

Characteristics of patients with cervical cancer during pregnancy: a multicenter matched cohort study. An initiative from the International Network on Cancer, Infertility and Pregnancy

BACKGROUND

Treatment of cervical cancer during pregnancy is often complex and challenging. This study aimed to analyze current patterns of practice in the management of pregnant patients diagnosed with cervical cancer.

METHODS

This was a matched cohort study comprising patients managed for cervical cancer during pregnancy from six European centers. Patient information was retrieved from the dataset of the International Network for Cancer, Infertility and Pregnancy from 1990 to 2012. Each center matched its patients with two non-pregnant controls for age (±5 years) and International Federation of Gynecology and Obstetrics (FIGO) 2009 stage. Information on age, histological type, grade, lymphovascular space invasion, stage, tumor size, method of diagnosis, site of recurrence, delivery, date of recurrence, and date of death was recorded. Progression-free survival was compared using multivariable Cox proportional hazards regression.

RESULTS

A total of 132 pregnant patients and 256 controls were analyzed. The pregnant patients (median age 34 years, range 21-43) were diagnosed at a median gestational age of 18.4 weeks of pregnancy (range 7-39). Stage distribution during pregnancy was 14.4% for stage IA, 47.0% for IB1, 18.9% for IB2, and 19.7% for II-IV. For treatment during pregnancy, 17.4% of the patients underwent surgery, 16.7% received neoadjuvant chemotherapy, 26.5% delayed their treatment, 12.9% had a premature delivery, and 26.5% had their pregnancy terminated. Median follow-up was 84 months (67 months for pregnant and 95 months for non-pregnant patients). The unadjusted hazard ratio of pregnancy for progression-free survival was 1.18 (95% confidence interval 0.74 to 1.88).

CONCLUSION

Surgery and chemotherapy is increasingly used in the management of pregnant patients with cervical cancer and prognosis is similar to that of non-pregnant 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.

Management of gynecological cancer in pregnant patients

INTRODUCTION

Cancer during pregnancy is a rare but challenging condition. More women delay childbearing and consequently the incidence of cancer during pregnancy is constantly increasing.

EVIDENCE ACQUISITION

An extensive electronic search was performed in PubMed and Scopus. Only studies written after 1985 were considered eligible for this review. Abstracts, conference papers, book chapters, animal studies, commentaries as well as editorials articles were excluded from this review.

EVIDENCE SYNTHESIS

Cancer treatment during pregnancy is possible, but both maternal and fetal conditions need to be preserved. Randomized clinical trials are not feasible and current evidence are mainly based on case-series, small case reports and expert opinion. Cervical and ovarian cancers are the most common gynecological cancers diagnosed during pregnancy. Surgery and chemotherapy after the first trimester seem to be relatively safe for the newborn. Platinum-based chemotherapy administered during the 2nd-3rd trimester showed comparable adverse effects in newborns to those in the general population. Babies exposed to antenatal chemotherapy might be more likely to develop small for gestational age and NICU admission, than babies not exposed.

CONCLUSIONS

Management of pregnant women with cancer should be performed in specialized cancer centers and all cases should be discussed with a multidisciplinary approach. In the present review, we discuss the current recommendations for the management of pregnancies complicated by cancer and neonatal outcomes.

Locally advanced cervical cancer complicating pregnancy: A case of competing risks from the Catholic University of the Sacred Heart in Rome

A case of stage IB2 cervical cancer at 27 weeks of pregnancy, treated with neoadjuvant chemotherapy followed by radical Cesarean hysterectomy with full pelvic and infra-mesenteric lymphadenectomy, and adjuvant chemo-radiation is described. While she remains without disease, her baby was diagnosed with acute myelogenous leukemia. We highlight the pre-operative work-up, treatment options, safety, feasibility, and outcomes for the mother and her fetus.

Current management of gynecologic cancer in pregnancy

Cancer during pregnancy is a particularly challenging complication. The incidence has increased in recent years due to childbearing at advanced maternal ages due to career choices and/or the development of reproductive technology. Approximately two thirds of cancer cases during pregnancy comprise invasive cervical cancers and breast cancer. Cancer during gestation is characterized by a need for specialized treatment due to major changes in the hormonal profile (estrogen-progesterone), metabolism (enhancement of anabolism), hemodynamic changes (hyperdynamic circulation), immunologic changes (cell-mediated and humoral immunity), and increased angiogenesis (increased blood flow towards the uterus). Moreover, the management of such patients is based on the trimester of pregnancy, type and stage of cancer, and informed consent of the mother based on her wishes. The optimal treatment of cancer during pregnancy remains elusive because there are limited data from retrospective studies with small samples. As a result, it is crucial that data regarding survival of the women and long-term follow-up of the children from different cancer centers and registries are shared. This need is dictated by the fact that the incidence of cancer during pregnancy will continue to rise as child-bearing age continues to increase.

Oncological management and obstetric and neonatal outcomes for women diagnosed with cancer during pregnancy: a 20-year international cohort study of 1170 patients

BACKGROUND

Awareness is growing that cancer can be treated during pregnancy, but the effect of this change on maternal and neonatal outcomes is unknown. The International Network on Cancer, Infertility and Pregnancy (INCIP) registers the incidence and maternal, obstetric, oncological, and neonatal outcomes of cancer occurring during pregnancy. We aimed to describe the oncological management and obstetric and neonatal outcomes of patients registered in INCIP and treated in the past 20 years, and assess associations between cancer type or treatment modality and obstetric and neonatal outcomes.

METHODS

This descriptive cohort study included pregnant patients with cancer registered from all 37 centres (from 16 countries) participating in the INCIP registry. Oncological, obstetric, and neonatal outcome data of consecutive patients diagnosed with primary invasive cancer during pregnancy between Jan 1, 1996, and Nov 1, 2016, were retrospectively and prospectively collected. We analysed changes over time in categorical patient characteristics, outcomes, and treatment methods with log-binomial regression. We used multiple logistic regression to analyse preterm, prelabour rupture of membranes (PPROM) or preterm contractions, small for gestational age, and admission to the neonatal intensive care unit (NICU). The INCIP registry study is registered with ClinicalTrials.gov, number NCT00330447, and is ongoing.

FINDINGS

1170 patients were included in the analysis and 779 (67%) received treatment during pregnancy. Breast cancer was the most common malignant disease (462 [39%]). Every 5 years, the likelihood of receiving treatment during pregnancy increased (relative risk [RR] 1·10, 95% CI 1·05-1·15), mainly related to an increase of chemotherapeutic treatment (1·31, 1·20-1·43). Overall, 955 (88%) of 1089 singleton pregnancies ended in a livebirth, of which 430 (48%) of 887 pregnancies ended preterm. Each 5 years, we observed more livebirths (RR 1·04, 95% CI 1·01-1·06) and fewer iatrogenic preterm deliveries (0·91, 0·84-0·98). Our data suggest a relationship between platinum-based chemotherapy and small for gestational age (odds ratio [OR] 3·12, 95% CI 1·45-6·70), and between taxane chemotherapy and NICU admission (OR 2·37, 95% CI 1·31-4·28). NICU admission seemed to depend on cancer type, with gastrointestinal cancers having highest risk (OR 7·13, 95% CI 2·86-17·7) and thyroid cancers having lowest risk (0·14, 0·02-0·90) when compared with breast cancer. Unexpectedly, the data suggested that abdominal or cervical surgery was associated with a reduced likelihood of NICU admission (OR 0·30, 95% CI 0·17-0·55). Other associations between treatment or cancer type and outcomes were less clear.

INTERPRETATION

Over the years, the proportion of patients with cancer during pregnancy who received antenatal treatment increased, especially treatment with chemotherapy. Our data indicate that babies exposed to antenatal chemotherapy might be more likely to develop complications, specifically small for gestational age and NICU admission, than babies not exposed. We therefore recommend involving hospitals with obstetric high-care units in the management of 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.

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.

Multidisciplinary Management of Breast Cancer During Pregnancy

BACKGROUND

Although breast cancer during pregnancy (BCDP) is rare (occurring with only 0.4% of all BC diagnoses in female patients aged 16-49 years), management decisions are challenging to both the patient and the multidisciplinary team.

MATERIALS AND METHODS

Experts in breast cancer at the University of North Carolina conducted a targeted literature search regarding the multidisciplinary treatment approaches to BCDP: medical, surgical, and radiation oncology. Supportive care, including antiemetic agents, and imaging approaches were also reviewed.

RESULTS

Review of the literature revealed key points in the management of BCDP. Surgical management is similar to that in nonpregnant patients; pregnant patients may safely undergo breast-conserving surgery. Recommendations should be tailored to the individual according to the clinical stage, tumor biology, genetic status, gestational age, and personal preferences. Anthracycline-based chemotherapy can be safely initiated only in the second and third trimesters. The rate of congenital abnormalities in children exposed to chemotherapy is similar to the national average (approximately 3%). Dosing of chemotherapy should be similar to that in the nonpregnant patient (i.e., actual body surface area). Antihuman epidermal growth factor receptor 2 therapy, radiation, and endocrine treatment are contraindicated in pregnancy and lactation. Care should include partnership with obstetricians. The literature regarding prognosis of BCDP is mixed.

CONCLUSION

To maximize benefit and minimize risk to the mother and fetus, an informed discussion with the patient and her medical team should result in an individualized treatment plan, taking into account the timing of the pregnancy and the stage and subtype of the breast cancer. Because BCDP is rare, it is essential to collect patient data in international registries. The Oncologist 2017;22:324-334 IMPLICATIONS FOR PRACTICE: Breast cancer during pregnancy is a major ethical and professional challenge for both the patient and the multidisciplinary treatment team. Although the oncologic care is based on that of the non-pregnant breast cancer patient, there are many challenges from regarding the medical, surgical and radiation oncology and obstetrical aspects of care that need to be considered to deliver the safest and best treatment plan to both the mother and developing fetus.

Squamous cell carcinoma antigen expression in tumor cells is associated with the chemosensitivity and survival of patients with cervical cancer receiving docetaxel-carboplatin-based neoadjuvant chemotherapy

The present study examined the association between squamous cell carcinoma antigen (SCCA) expression and the response of patients with cervical cancer to docetaxel-carboplatin (DC) combination chemotherapy, in order to determine the prognostic potential of SCCA expression. A total of 21 patients were enrolled with stage IB2 or stage IIA2 SCC. Of these, 9 patients had chemotherapy-sensitive cancer (2 cases with a complete response and 7 cases with a partial response) and 12 patients had chemotherapy-resistant cancer (12 cases of stable disease and no cases of progressive disease). Patients were treated with two cycles of DC chemotherapy (docetaxel 75 mg/m² plus cisplatin 25 mg/m²) with 21-day intervals, followed by radical surgery. SCCA expression levels prior to and following chemotherapy were evaluated using immunohistochemistry. Following DC chemotherapy, the SCCA expression levels decreased in the patients with chemotherapy-sensitive cancer, but not in those with chemotherapy-resistant cancer (P=0.042). Significant survival differences between the SCCA-positive and -negative patients following chemotherapy (P=0.009) was observed. However, no statistically significant difference in survival between patients with chemotherapy-sensitive and chemotherapy-resistant cancer, or between patients with SCCA-positive and -negative expression prior to chemotherapy was observed. Overall, the chemotherapy sensitivity of patients with cervical cancer was associated with decreased SCCA expression levels following DC chemotherapy. Therefore, SCCA expression levels following DC chemotherapy may potentially be used in the clinical prognosis for cervical cancer patients who receive DC chemotherapy and subsequent radical surgery.

Use of anticancer agents in gynecological oncology during pregnancy: a systematic review of maternal pharmacokinetics and transplacental transfer

INTRODUCTION

Cancer affects one in a thousand pregnant women and gynecological cancers are one of the most frequent malignancies. Chemotherapy remains the cornerstone treatment for gynecological cancer. Although all chemotherapeutic agents can cross the placental barrier, the extent of placental transfer varies considerably. Furthermore, the significant physiological variations observed in pregnant women may have an impact on pharmacokinetic parameters. Given the complexity of predicting placental transfer, in vivo and ex vivo studies are essential in this context. In view of the paucity of data on chemotherapy during pregnancy, the objective of the present study was to summarize all the available data on the transplacental transfer of anticancer drugs used to treat gynecological cancers.

AREAS COVERED

In order to evaluate the in vivo and ex vivo transplacental transfer of the anticancer drugs most frequently used in gynecological malignancies, we carried out a comprehensive review of the literature published from 1967 to 2015. Lastly, we summarized recent clinical guidelines on the treatment of gynecological cancers in pregnant patients.

EXPERT OPINION

The preclinical and scarce clinical data must now be extrapolated to define the maternofetal toxicity/efficacy profile and thus guide the physicians to choose anticancer drugs more efficiently in this complex situation.

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.
