A Case of Painful Growing Abdominal Wall Mass during Pregnancy Requiring Resection in the Second Trimester.

Desmoid fibromatosis (DF) is a rare and locally aggressive neoplasm. We present a case of a 28-year-old previously healthy multigravida who noticed a lump in her abdomen near the umbilicus two months before becoming pregnant. It underwent rapid growth during pregnancy, causing pain and discomfort. Targeted ultrasound of the area showed an irregular mass measuring 0.9 × 1.7 × 1.4 cm. The origin of the mass was unclear, suggesting a connection with the intra-abdominal contents. An MRI done three weeks later revealed a subcutaneous ovoid mass measuring 3.0 × 2.3 × 3.0 cm, which was significantly larger. Due to pain and rapid growth, surgical resection was done at 25 weeks of pregnancy. Histopathological examination revealed a desmoid tumor. The patient had an uneventful recovery and term vaginal delivery without complications. Hence, our case serves as evidence that DF tumors can be surgically managed during pregnancy with minimal to no complications.

Outcome of breast cancer patients treated with chemotherapy during pregnancy compared with non-pregnant controls.

BACKGROUND: A diagnosis of breast cancer during pregnancy (PrBC) does not impact prognosis if standard treatment is offered. However, caution is warranted as gestational changes in pharmacokinetics may lead to reduced chemotherapy concentration. METHODS: Survival of PrBC patients treated with chemotherapy during pregnancy was compared to non-pregnant breast cancer patients treated with chemotherapy, diagnosed after 2000, excluding patients older than 45 years or with a postpartum diagnosis. The data was registered in two multicenter registries (the International Network of Cancer, Infertility and Pregnancy and the German Breast Group). Cox proportional hazards regression was used to compare disease-free (DFS) and overall survival (OS) between both groups, adjusting for age, stage, grade, hormone receptor status, human epidermal growth factor 2 status and histology, weighted by propensity scoring to account for the differences in baseline characteristics between pregnant patients and controls. RESULTS: In total, 662 pregnant and 2081 non-pregnant patients were selected. Pregnant patients were more likely to have stage II breast cancer (60.1% vs 56.1%, p = 0.035), grade 3 tumors (74.0% vs 62.2%, p < 0.001), hormone receptor-negative tumors (48.4% vs 34.0%, p < 0.001) or triple-negative breast cancer (38.9% vs 26.9%, p < 0.001). Median follow-up was 66 months. In multivariable analysis, DFS and OS were comparable for pregnant and non-pregnant patients (DFS: HR 1.02, 95% CI 0.82-1.27, p = 0.83; OS: HR 1.08, 95% CI 0.81-1.45, p = 0.59). CONCLUSION: Outcome of women with breast cancer treated with chemotherapy during pregnancy is comparable to young non-pregnant women. These results support chemotherapy for PrBC when indicated.

Paclitaxel use in pregnancy: neonatal follow-up of infants with positive detection of intact paclitaxel and metabolites in meconium at birth.

Paclitaxel is often excluded during pregnancy for women with breast cancer due to limited neonatal follow-up. We confirmed in utero fetal Paclitaxel exposure for 8 newborns. Birth details and follow-up to 36 months of age is reported. Meconium samples from newborns exposed to chemotherapy were screened by liquid chromatography-high resolution mass spectrometry while blinded to maternal treatment during pregnancy. Newborn information at birth and annually was obtained. Mean gestational age (GA) at cancer diagnosis and start of chemotherapy was 8.7 + 6.2 weeks and 17.1 ± 3.5 weeks. Paclitaxel was started at a mean GA of 27.0 ± 5.8 weeks. Paclitaxel followed Doxorubicin/Cyclophosphamide in 6 cases, 5-Fluouracil/Doxorubicin/Cyclophosphamide in 1, and was used alone in 1. Mean number of days between Paclitaxel and birth was 23 ± 15. Identification of Paclitaxel and/or metabolites was made in all meconium from paclitaxel-exposed fetuses. Birthweight was < 10% for GA in 3 infants. Three anomalies occurred: mild hip dysplasia without further treatment and mitral valve stenosis. The third child was diagnosed with Cleidocranial Dysostosis, a familial anomaly. Mean age at pediatric follow-up is 18.7 + 9.3 months. Pediatricians report eczema and recurrent otitis media in 1 child, iron deficiency anemia and upper respiratory infection in 2. One child is < 10% for height and weight at 15 months. All are meeting developmental milestones at median age of 18.7 months, range: 6-36 months. CONCLUSION: Up to 3 years of age, follow-up of neonates exposed to Paclitaxel in utero is reassuring. Continued observation of neonatal development is essential. WHAT IS KNOWN: • Chemotherapy during the second and third trimester of pregnancy does not result in an increase in congenital malformations or developmental delay. • In non-human primate studies by Van Calsteren et al., variable plasma and/or tissue concentrations of taxanes, carboplatin, and trastuzumab were encountered in the fetal compartment. • Pilot data reported by the current investigators proved that paclitaxel crosses the human placenta. WHAT IS NEW: • This current article provides medical and developmental follow up on the newborns from this exposure for 3 years after birth.

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.

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.

Development of children born to mothers with cancer during pregnancy: comparing in utero chemotherapy-exposed children with nonexposed controls.

OBJECTIVE: Cancer is diagnosed in approximately 1 per 1000 pregnant women. Lifesaving cancer therapy given to the mother during pregnancy appears in conflict with the interest of the developing fetus. Often, termination of pregnancy is suggested but has not been proven in any type of cancer to improve maternal prognosis, while very few studies have documented the long-term effects of in utero chemotherapy exposure on child outcome. To counsel patients about the risk of continuing a pregnancy while undergoing cancer treatment, we performed developmental testing to provide more detailed follow-up on children exposed in utero to chemotherapy. STUDY DESIGN: Mother-infant pairs, enrolled in the Cancer and Pregnancy Registry, were offered developmental testing for children who were ≥18 months of age. Based on age, the Bayley Scales of Infant Development-Third Edition, the Wechsler Preschool and Primary Scale of Intelligence-Revised, the Wechsler Intelligence Scale for Children, Third Edition, or the Wechsler Individual Achievement Test was administered. All parents or primary caregivers completed the Child Behavior Checklist, a parent questionnaire to assess behavior and emotional issues. Results of children exposed to chemotherapy before delivery were compared with children whose mothers were also diagnosed with cancer during pregnancy but did not receive chemotherapy before delivery. RESULTS: No significant differences were noted in cognitive skills, academic achievement, or behavioral competence between the chemotherapy-exposed group and the unexposed children. Of children, 95% scored within normal limits on cognitive assessments; 71% and 79% of children demonstrated at or above age equivalency in mathematics and reading scores, respectively; and 79% of children scored within normal limits on measures of behavior. Older children had significantly higher rates of internalizing behavior problems. CONCLUSION: We could not demonstrate a significant difference in cognitive ability, school performance, or behavioral competence for children exposed to chemotherapy in utero compared with nonexposed controls. The majority of these children scored within normal limits on all developmental measures. Premature birth was more prevalent in the chemotherapy-exposed group yet did not predict developmental outcome. Older children in the sample demonstrated higher rates of internalizing behavior problems.

Safety considerations: breastfeeding after transplant.

Organ transplant is an effective treatment for end-stage organ failure. For women, restoration of organ function can restore fertility and the ability to successfully carry a pregnancy. Posttransplant pregnancies have been reported among recipients of all types of solid organ transplants via case and center reports plus registry data. Stable graft function is dependent on prevention of rejection, currently accomplished by using maintenance immunosuppressant medications, to which the fetus is exposed in utero. Common among neonatal outcomes in transplant recipients are preterm and low-birth-weight infants. Emotional, nutritional, and immunologic benefits of breastfeeding have been well-documented and could be valuable for these newborns. Concern must be directed at the effects of the child's exposure to immunosuppressive agents excreted into the breast milk. Breastfeeding could be considered in transplant recipients if it can be shown that the level of exposure does not result in risks to the newborn, immediately and throughout childhood. Despite concerns of health care professionals, some recipients have chosen to breastfeed. Breastfeeding after transplant must be approached with consideration of many issues, and the potential risks require further study. This review focuses on benefits of breastfeeding, common immunosuppressive agents used in organ transplant recipients, a summary of the reports of women who have breastfed their infants while on immunosuppressive therapy and the published studies on breastfeeding and immunosuppressive agents. Recommendations are provided to guide health care professionals to help mothers receiving immunosuppressive agents to make informed choices about breastfeeding their infants.

The psychological impact of a cancer diagnosed during pregnancy: determinants of long-term distress.

BACKGROUND: Cancer occurs during one in 1000-5000 of the approximately 6 million yearly US pregnancies identified by the American Pregnancy Association. Although a newly diagnosed cancer is associated with substantial distress, little is known about cancer's emotional impact on women when diagnosed during pregnancy, and no studies have been conducted on the subject. OBJECTIVE: The Cancer and Pregnancy Registry was developed by Elyce H. Cardonick MD, specialist in Maternal and Fetal Medicine and Associate Professor of Obstetrics and Gynecology at Robert Wood Johnson Medical School, to examine the consequences of maternal cancer diagnosis and treatment during pregnancy on maternal, fetal, and neonatal outcomes, including the impact of in utero exposure to chemotherapy. METHODS: Participants were asked to complete questionnaires, including measures of psychological distress, permitting the examination of variables associated with long-term psychological distress in women following a cancer diagnosis in pregnancy. RESULTS: Seventy-four women completed the Brief Symptom Inventory-18 and Impact of Event Scale on average 3.8 years (SD 2.5) following their cancer diagnosis. Potential variables related to distress included information on: sociodemographics, disease, pregnancy, birth, cancer treatment, and health status. Multiple regression analyses revealed that women were at higher risk of long-term distress if they had not received fertility assistance, had been advised to terminate the pregnancy, had had a preterm baby, had had a cesarean delivery, had not produced sufficient milk to breastfeed, had been experiencing a recurrence, and/or had undergone surgery post-pregnancy. CONCLUSION: Results are discussed in light of our current knowledge of the normal developmental phase of pregnancy and motherhood.

Immunosuppression in pregnancy: choices for infant and maternal health.

Successful pregnancy outcomes are possible after all types of solid organ transplantation and thousands of successful pregnancies in such women have been reported. As immunosuppressive medications are required to maintain adequate graft and maternal survival, major concerns are the effect of these agents on the fetus and the effect of pregnancy on the well being of mother and graft, against a background of continuing advances and modifications in immunosuppressive therapy. Women should avoid unnecessary medications during pregnancy but clinicians worry most about teratogens; agents (environmental, pharmaceuticals or other chemicals) that cause abnormal development, whether this be an overt structural birth defect or more subtle derangements of embryonic or fetal development. A concern is that any agent or combination of agents and maternal condition(s) may be teratogenic, a risk that is increased in the transplant population. The goal of immunosuppression is to ensure graft and patient survival by preventing acute rejection. Combinations of agents allow for synergistic effects while minimising drug toxicities. No specific combination has been deemed optimal and the effects of more recently available combinations require further study. Although there are known theoretical risks to mother and fetus, successful pregnancies are now the rule in transplant recipients. This is without an apparent increase in the type or incidence of malformations in the newborns, and usually with no evidence of graft dysfunction and/or irreversible deterioration either related to prepregnancy graft problems or unpredictable gestational factors. For immunosuppression, what is best for the mother and her survival should ensure the best outcome for the fetus and, although no specific malformation pattern has been reported to date, there are some interesting trends worthy of continued analyses. A balance of good maternal and graft outcome with the lowest risk of fetal toxicity must be the goal of management.
