Use of chemotherapy during human pregnancy

Paradigm Shifts in Hodgkin Lymphoma Treatment: From Frontline Therapies to Relapsed Disease

Combination chemotherapy with or without radiation has served as the primary therapeutic option for classic Hodgkin lymphoma (cHL), leading to durable remission in a majority of patients with early- and advanced-stage cHL. Patients with relapsed/refractory (RR) cHL could still be cured with salvage chemotherapy and autologous stem-cell transplantation. Brentuximab vedotin (BV) and the anti-PD-1-blocking antibodies, nivolumab and pembrolizumab, are highly effective treatments for cHL and have revolutionized the management of the disease. Recent studies incorporating BV and PD-1 blockade into salvage therapy for RR cHL and into frontline treatment regimens have changed the cHL treatment paradigm. The novel agents are also useful in the treatment of older patients who have poor outcomes with traditional therapy. This manuscript will review current strategies for approaching the management of previously untreated, RR, and challenging populations with cHL, including how to incorporate the novel agents.

A long-term retrospective analysis of management of cervical cancer during pregnancy

OBJECTIVE

This study aims to describe cervical cancer during pregnancy (CCP) and investigate factors associated with survival outcomes.

METHODS

This retrospective matched study included CCP patients from May 2007 to August 2021 and matched non-pregnant cervical cancer patients (1:2) based on age (±5 years), year at diagnosis (±2 years), histological type and stage (2018 FIGO). The Kaplan-Meier method and multivariate Cox regression analyses were used to assess the impact of pregnancy and clinicopathologic factors on prognosis.

RESULTS

Thirty-eight CCP patients (stage IA to IIIC) and 76 non-pregnant patients were included. Most CCP patients were diagnosed in the first (31.6%) or second (47.4%) trimester. CCP patients had a longer waiting time than non-pregnant patients. Pregnancy continued in 42.1% (continuation of pregnancy [COP] group) and was terminated in 57.9% (termination of pregnancy [TOP] group) of patients. Survival analysis showed no significant differences in recurrence-free survival (RFS) or overall survival (OS) between pregnant and non-pregnant patients or between the COP and TOP groups. At the end of the follow-up period (range 12-178 months), 23 children born to CCP patients exhibited normal development.

CONCLUSION

Pregnancy does not impact cervical cancer prognosis. The oncologic outcomes of the TOP and COP groups were comparable. A pregnancy-preserving strategy could be considered for managing CCP patients.

Diagnosis and management of acute promyelocytic leukemia: Brazilian consensus guidelines 2024 on behalf of the Brazilian Association of Hematology, Hemotherapy and Cellular Therapy

Improvements in clinical assessment have occurred since the last published recommendations on the diagnosis and treatment of acute promyelocytic leukemia in 2013. Here, a committee of specialists of the Brazilian Association of Hematology, Hemotherapy and Cellular Therapy presents a comprehensive review on the current knowledge, focusing on the advances in diagnosis, risk assessment, and frontline and salvage therapy. The concept of urgent diagnosis is explored as well as the management of critical situations such as coagulopathy and differentiation syndrome. Recent adjustments in risk stratification based on white blood cell counts only are presented together with the incorporation of chemo-free regimens for non-high-risk patients. Special conditions such as acute promyelocytic leukemia in children, the elderly and pregnant women are discussed. Finally, acute promyelocytic leukemia is presented as a highly curable disease because of the real possibility of targeted therapy towards differentiation, and, paradoxically, as a serious and urgent condition that deserves prompt recognition and management to avoid early mortality.

School performance and educational achievement in children exposed to maternal cancer in utero

BACKGROUND

In utero exposure to maternal cancer and cancer treatment might influence the child's cognitive development. This study investigated if exposure to maternal cancer during fetal life impacted school performance and educational achievement as adults.

METHODS

This nationwide retrospective cohort study identified all live-born children in Denmark between January 1978 and December 2013. Exposure was defined as maternal cancer diagnosis during pregnancy. Four partly overlapping birth cohorts were constructed depending on the outcome of interest: (1) receiving special educational support for birth years 2001-2013; (2) grade point average (GPA) at the final exams after 10th grade for 1986-2003; (3) educational achievement at 20 years for 1978-1998; and (4) education at 30 years for 1978-1988. Logistic and linear models were adjusted for birth year, maternal age, maternal education and maternal death.

RESULTS

The estimated probability of receiving special educational support was similar in the exposed group and the reference (adjusted OR 0.96; 95% CI 0.46 to 1.77, non-significant). The GPA did not statistically differ (0.13 grade points; 95% CI -0.18 to 0.45, non-significant). The achieved educational levels were similar for the exposed group and the reference at 20 years, with an adjusted OR of 1.07 (95% CI 0.82 to 1.40) for low versus medium educational level, and at 30 years with an adjusted OR of 0.73 (95% CI 0.35 to 1.50) for low versus high educational level and of 1.07 (95% CI 0.66 to 1.72) for medium versus high educational level.

CONCLUSION

Our findings did not indicate poorer performance in compulsory school nor impairment of adult educational achievement after exposure to maternal cancer in utero.

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.

Pregnancy-Associated Cancer: A Systematic Review and Meta-Analysis

This study aimed to systematically evaluate and quantify the risk of adverse maternal and neonatal outcomes in patients with pregnancy-associated cancer (PAC). This study was conducted from February 13, 2021, through July 24, 2023. A systematic search of MEDLINE, Embase, Web of Science Core Collection, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials was conducted to identify studies reporting outcomes for patients with PAC. The study was registered on PROSPERO. Two reviewers independently conducted screening, data extraction, and quality assessment. The associations were quantified using random-effects meta-analysis. The initial search produced 29,401 titles and abstracts, after which 147 unique full-text articles were screened, of which 22 articles with 59,190 pregnancies with PAC from 70,097,167 births were included in the meta-analysis. Women with PAC were at significantly increased risk of cesarean deliveries (risk ratio [RR], 1.58; 95% CI, 1.31-1.89), preterm birth (RR, 3.07; 95% CI, 2.37-3.98), venous thromboembolism (RR, 6.76; 95% CI, 5.08-8.99), and maternal death (RR, 41.58; 95% CI, 20.38-84.83). The only outcome with reduced risk was instrumental mode of delivery (RR, 0.67; 95% CI, 0.52-0.87). Pregnancy-associated cancer increases risk of adverse outcomes, including a 7-fold risk of venous thromboembolism and a 42-fold risk of maternal death. Further research is required to better understand the mechanisms leading to these adverse outcomes, especially for women who are not diagnosed until the postpartum period. Affected women should have counseling regarding their increased risk of adverse outcomes.

Drug-induced fetal and offspring disorders, beyond birth defects

Studies on drug utilization in western countries disclosed that about nine over ten women use at least one or more drugs during pregnancy. Determining whether a drug is safe or not in pregnant women is a challenge of all times. As a developing organism, the fetus is particularly vulnerable to effects of drugs used by the mother. Historically, research has predominantly focused on birth defects, which represent the most studied adverse pregnancy outcomes. However, drugs can also alter the ongoing process of pregnancy and impede the general growth of the fetus. Finally, adverse drug reactions can theoretically damage all developing systems, organs or tissues, such as the central nervous system or the immune system. This extensive review focuses on different aspects of drug-induced damages affecting the fetus or the newborn/infant, beyond birth defects, which are not addressed here.

Pregnancy and neonatal outcomes following malignancy in pregnancy at a tertiary care Canadian center: a retrospective chart review

Objective: Data on pregnancy-associated cancers (PACs) are lacking. The objectives of this study were to determine the incidence of PACs and describe the characteristics and outcomes of pregnancies affected by malignancy at a single tertiary care center in Ottawa, Canada.Methods: This was a retrospective chart review of individuals with PAC at The Ottawa Hospital (TOH) between 2011-2022. Eligible cases were identified from the TOH Data Warehouse, the TOH instance of the Better Outcomes Registry & Network Ontario, and the TOH Division of Maternal Fetal Medicine's Perinates database. Chart reviews were conducted to confirm case eligibility and to extract demographic, oncologic, obstetrical, and neonatal measures. The annual incidence of PAC over the 11-year period was reported per 1000 deliveries. Descriptive statistics were used to describe the sample, including frequency (n) and proportions (%) for categorical variables and mean and standard deviation (SD) for continuous variables.Results: The final cohort included 59 individuals with PAC at TOH between 2011-2022. The annual incidence of PAC ranged from 0.47 to 1.54 per 1000 deliveries. The most common PACs were breast cancer (28.8%), Hodgkin lymphoma (10.2%), and thyroid cancer (8.5%). Common interventions during pregnancy included chemotherapy (33.9%) and surgical intervention (32.2%). A total of 19 individuals (32.2%) did not undergo PAC-related treatment during pregnancy. There were 55 livebirths (91.7%), 2 spontaneous abortions (3.3%), 3 induced abortions (5.0%), and no stillbirths. Among livebirths, the mean gestational age was 37.4 ± 2.8 weeks and the mean birthweight was 2920.3 ± 650.0 g. All neonates had reassuring 5-minute Apgar scores, 18 (32.7%) were admitted to the Neonatal Intensive Care Unit/Special Care Nursery (NICU/SCN), and 8 (14.5%) were noted to have a mild congenital abnormality.Conclusion: This study shows promising perinatal outcomes for patients with PAC and their neonates. Ongoing surveillance of PAC is needed to better inform care for this patient population.

Clinical Features and Management of Lung Cancer During Pregnancy: A Narrative Review Based on Reported Cases

This review aims to provide a summary of the clinical characteristics and outcomes of lung cancer during pregnancy. A comprehensive literature search yielded 93 cases of lung cancer during pregnancy from 1953 to 2022, with an average maternal age of ∼34 years old. The initial symptoms reported were often nonspecific, such as cough, dyspnea, and chest pain. Cancer-related treatments, including surgery, radiotherapy, chemotherapy, and tyrosine kinase inhibitors, have shown beneficial effects on maternal outcomes. A majority of the newborns were born without malformation or diseases, but extended follow-up remains necessary. Early diagnosis of lung cancer is imperative for reducing the risks of placental and fetal metastasis and enhancing overall survival.

Spontaneous and induced abortions in women with a diagnosis of gestational related neoplasm: a population-based linkage study in Lombardy, 2010-2020

BACKGROUND

A diagnosis of cancer during pregnancy or within one year after the end of pregnancy is a major clinical and public health issue. The current study aimed at estimating the incidence of pregnancy-associated cancer (PAC) and assessing whether the risk of abortion is increased in women diagnosed with cancer.

METHODS

This population-based cohort study used the regional healthcare utilization (HCU) databases of Lombardy, the largest region in Italy, to identify the women who delivered between 2010 and 2020. PAC were identified by oncological ICD-9-CM codes reported in the hospital discharge forms. We computed the ratio of PAC cases to the total number of pregnancies. Following a diagnosis of PAC, the prevalence ratio (PR) of abortion and the corresponding 95% confidence interval (CI), was estimated using a log-binomial model adjusted for maternal age.

RESULTS

During the study period, 926 women who gave birth (1.29 cases per 1000 births) and 341 women who had an abortion (1.52 cases per 1000 abortions) were diagnosed with PAC. Regardless of the outcome of pregnancy, the risk of PAC increased with increasing age. The rate of PAC was initially lower among births, but it came very close to the rate of PAC among abortions in the last two calendar years. The proportion of abortions among women with PAC gradually decreased from 27.7% in 2010-2012 to 18.5% in 2019-2020 (p-value < 0.001). Overall, a diagnosis of PAC was related to an approximately 10% increased risk of abortion (PR = 1.11, 95%CI:1.01-1.22). However, no association was observed in 2019-2020 (PR = 0.87, 95%CI:0.65-1.17). Considering only diagnoses made during the first trimester of pregnancy, the risk of abortion was about 2.5 times higher (PR = 2.53, 95%CI:2.05-3.11) and the risk of induced abortion was almost 4 times higher (PR = 3.71, 95%CI:2.82-4.90).

CONCLUSION

In this population the risk of abortion was about 10% higher in women with PAC than in women without PAC. However, this association tended to decrease in more recent calendar periods. This trend seemed to be influenced more by spontaneous than by induced abortions.

Awake craniotomy during pregnancy: A systematic review of the published literature

Neurosurgical pathologies in pregnancy pose significant complications for the patient and fetus, and physiological stressors during anesthesia and surgery may lead to maternal and fetal complications. Awake craniotomy (AC) can preserve neurological functions while reducing exposure to anesthetic medications. We reviewed the literature investigating AC during pregnancy. PubMed, Scopus, and Web of Science databases were searched from the inception to February 7th, 2023, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. Studies in English investigating AC in pregnant patients were included in the final analysis. Nine studies composed of nine pregnant patients and ten fetuses (one twin-gestating patient) were included. Glioma was the most common pathology reported in six (66.7%) patients. The frontal lobe was the most involved region (4 cases, 44.4%), followed by the frontoparietal region (2 cases, 22.2%). The awake-awake-awake approach was the most common protocol in seven (77.8%) studies. The shortest operation time was two hours, whereas the longest one was eight hours and 29 min. The mean gestational age at diagnosis was 13.6 ± 6.5 (2-22) and 19.6 ± 6.9 (9-30) weeks at craniotomy. Seven (77.8%) studies employed intraoperative fetal heart rate monitoring. None of the AC procedures was converted to general anesthesia. Ten healthy babies were delivered from patients who underwent AC. In experienced hands, AC for resection of cranial lesions of eloquent areas in pregnant patients is safe and feasible and does not alter the pregnancy outcome.

Cancer and Pregnancy in the Post-Roe v. Wade Era: A Comprehensive Review

Cancer during pregnancy, affecting 1 in 1000 pregnancies, is rising in incidence due to delayed childbearing and improved detection. Common types include breast cancer, melanoma and cervical cancer and Hodgkin's Lymphoma. There are several physiological changes that occur during pregnancy that make its management a challenge to clinicians. Managing it requires multidisciplinary approaches and cautious test interpretation due to overlapping symptoms. To minimize fetal radiation exposure, non-ionizing imaging is preferred, and the interpretation of tumor markers is challenging due to inflammation and pregnancy effects. In terms of treatment, chemotherapy is avoided in the first trimester but may be considered later. Immunotherapy's safety is under investigation, and surgery depends on gestational age and cancer type. Ethical and legal concerns are growing, especially with changes in U.S. abortion laws. Access to abortion for medical reasons is vital for pregnant cancer patients needing urgent treatment. Maternal outcomes may depend on the type of cancer as well as chemotherapy received but, in general, they are similar to the non-pregnant population. Fetal outcomes are usually the same as the general population with treatment exposure from the second trimester onwards. Fertility preservation may be an important component of the treatment discussion depending on the patient's wishes, age and type of treatment. This article addresses the complicated nature of a diagnosis of cancer in pregnancy, touching upon the known medical literature as well as the ethical-legal implications of such a diagnosis, whose importance has increased in the light of recent judicial developments.

Choosing the appropriate pharmacotherapy for breast cancer during pregnancy: what needs to be considered?

INTRODUCTION

Breast cancer is the most commonly diagnosed malignancy during pregnancy. Breast cancer during pregnancy is a challenging clinical condition requiring proper and timely multidisciplinary management.

AREAS COVERED

This review focuses on the management of breast cancer during pregnancy with a focus about the current state-of-the-art on the feasibility and safety of pharmacotherapy approaches in this setting.

EXPERT OPINION

Multidisciplinary care is key for a proper diagnostic-therapeutic management of breast cancer during pregnancy. Engaging patients and their caregivers in the decision-making process is essential and psychological support should be provided. The treatment of patients with breast cancer during pregnancy should follow the same recommendations as those for breast cancer in young women outside pregnancy but taking into account the gestational age at the time of treatment.Anthracycline-, cyclophosphamide-, and taxane-based regimens can be safely administered during the second and third trimesters with standard protocols, preferring weekly regimens whenever possible. Endocrine therapy, immune checkpoint inhibitors, and targeted agents are contraindicated throughout pregnancy, also due to the very limited data available to guide their administration in this setting. During treatment, careful fetal growth monitoring is mandatory, and even after delivery proper health monitoring for the children exposed in utero to chemotherapy should be continued.

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.

Pregnancy-associated Cancer and Chemotherapy during Pregnancy

The diagnosis of pregnancy-associated cancer, although rare, is a condition of great human and social significance and difficult clinical management. A pregnancy-associated neoplasm is defined as a cancer diagnosis made during pregnancy or within 12 months after delivery/abortion. The most common cancers in pregnancy occur most frequently in women of reproductive age with an incidence overall like that observed in non-pregnant women of the same age. This incidence is likely to increase in view of both the expected increase in certain malignancies among young women (particularly breast cancer and melanoma) and the increasing frequency of pregnancies undertaken later in life (fourth and fifth decades of life) that is characterizing modern society. Chemotherapy is generally contraindicated before 12 weeks of pregnancy due to the increased risk of congenital anomalies while exposure in the second and third trimester of pregnancy to chemotherapy has been associated with more growth restriction and preterm delivery. Clinical decisions about the optimal management should consider maternal and fetal characteristics with the involvement of a multidisciplinary team.

Lymphomas in pregnancy

Lymphoma in pregnancy is an uncommon occurrence. This diagnosis is challenging, and a multidisciplinary team of specialists in obstetrics, anesthesiology, neonatology, hematology psychology should participate in the management of this condition. The choice of treatment regimen depends on the histotype and the gestational age. In Hodgkin lymphoma, ABVD is safe if administered after the thirteenth week of pregnancy. In indolent non-Hodgkin Lymphomas (NHL) a watchful waiting approach is reasonable; in case of aggressive NHLs, if the diagnosis occurs in the first gestational weeks, a termination of the pregnancy might be considered or if it occurs after the thirteenth week of pregnancy, a standard R-CHOP regimen is safe. Regarding new anti-lymphoma drugs, available data on the potential fetotoxicity of these agents are limited. Data collection regarding the use of new drugs in pregnant patients is mandatory in order to learn more about their safety and facilitating clinical decision making in this setting of patients.

Pregnancy and Gastric Cancer: A Narrative Review

Cases of digestive cancers diagnosed during pregnancy are rare. The increasing prevalence of pregnancy in women aged 30-39 years (and not exceptionally 40-49 years) could explain the frequent co-occurrence of cancers and pregnancy. The diagnosis of digestive cancers in pregnancy is difficult due to the overlap between neoplasm symptomatology and the clinical picture of pregnancy. A paraclinical evaluation may also be difficult depending on the trimester of the pregnancy. Diagnosis is also delayed by practitioners' hesitation to use invasive investigations (imaging, endoscopy, etc.) due to fetal safety concerns. Therefore, digestive cancers are often diagnosed during pregnancy in advanced stages, where complications such as occlusions, perforations, and cachexia have already arisen. In this review, we highlight the epidemiology, clinical aspects, paraclinical evaluation, and particularities of the diagnosis and treatment of gastric cancer during pregnancy.

Patient-Centered Care in the Management of Cancer During Pregnancy

The management of cancer during pregnancy requires a patient-centered, multidisciplinary approach to balance maternal and fetal well-being given the rarity of this clinical scenario and lack of substantial data. Involvement of oncology and nononcology medical specialists and ethical, legal, and psychosocial supports, as needed, is instrumental in navigating the complexities of care for this patient population. Critical periods of fetal development and physiological changes in pregnancy must be considered when planning diagnostic and therapeutic approaches during pregnancy. The complexity of symptom recognition and interventional approaches contributes to diagnostic delays of cancers during pregnancy. Ultrasound and whole-body diffusion-weighted magnetic resonance imaging are safe throughout pregnancy. Surgery can be safely performed throughout pregnancy, with the early second trimester preferred for intra-abdominal surgery. Chemotherapy can be safely administered after 12-14 weeks of gestation until 1-3 weeks before the anticipated delivery. Most targeted and immunotherapeutic agents are contraindicated during pregnancy because of limited data. Pelvic radiation during pregnancy is absolutely contraindicated, while if radiation to the upper body is needed, administration should only be considered early in pregnancy. To ensure that the total cumulative fetal exposure to ionizing radiation does not exceed 100 mGy, early inclusion of the radiology team in the care plan is required. Closer prenatal monitoring is recommended for maternal and fetal treatment-related toxicities. Delivery before 37 weeks of gestation should be avoided if possible, and vaginal delivery is preferred unless obstetrically indicated or specific clinical scenarios. Postpartum, breastfeeding should be discussed, and the neonate should receive blood work to assess for acute toxicities with follow-up arranged for long-term monitoring.

Maternal and neonatal outcomes in women with a history of chemotherapy exposure: a population-based study of 8 million obstetric admissions

PURPOSE

With improvement in cancer care and fertility preservation, increasing numbers of cancer survivors are requiring obstetrical care. The objective of our study was to evaluate the effect of history of chemotherapy exposure on maternal and neonatal outcomes.

METHODS

A retrospective population-based cohort study was conducted using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) to obtain data on maternal and newborn outcomes in a cohort of births occurring between the years 2006 and 2015. The annual and overall prevalence of chemotherapy exposure was calculated among pregnant women, and multivariate logistic regression models were used to estimate the effect of history of exposure to chemotherapy on the risk of adverse maternal and newborn outcomes.

RESULTS

Of 7,907,139 birth admissions, 613 had a history of chemotherapy exposure for an overall incidence of 7.75 per 100,000 admissions. The prevalence of chemotherapy exposure in pregnancy increased during the study period (P < 0.001). Women with a history of chemotherapy were more likely to suffer from obstetric and medical complications including pre-eclampsia, chorioamnionitis, postpartum hemorrhage, and venous thromboembolism as well as an increased risk in overall mortality (OR 9.39, 95% CI 1.31-67.32). No differences were observed in the incidence of adverse neonatal outcomes, including stillbirth, intra-uterine growth restriction, or preterm birth.

CONCLUSION

Women with history of chemotherapy have higher incidence of pregnancy complications and maternal death, with no differences in fetal or newborn outcomes.

Pregnancy-Associated Breast Cancer: A Diagnostic and Therapeutic Challenge

Pregnancy-associated breast cancer (PABC) is commonly defined as a breast cancer occurring during pregnancy, throughout 1 year postpartum, or during lactation. Despite being a rare circumstance, PABC is one of the most common types of malignancies occurring during pregnancy and lactation, with growing incidence in developed countries, due both to decreasing age at onset of breast cancer and to increasing maternal age. Diagnosis and management of malignancy in the prenatal and postnatal settings are challenging for practitioners, as the structural and functional changes that the breast undergoes may be misleading for both the radiologist and the clinician. Furthermore, safety concerns for the mother and child, as well as psychological aspects in this unique and delicate condition, need to be constantly considered. In this comprehensive review, clinical, diagnostic, and therapeutic aspects of PABC (including surgery, chemotherapy and other systemic treatments, and radiotherapy) are presented and fully discussed, based on medical literature, current international clinical guidelines, and systematic practice.

A pregnant patient with ALK-positive non-small cell lung cancer treated with alectinib: A case report and review of the literature

Oncogenic rearrangements in the anaplastic lymphoma kinase (ALK) gene account for 5% of non-small cell lung cancer (NSCLC) cases. ALK inhibitors have markedly improved the outcome of metastatic ALK-positive NSCLC (ALK⁺ mNSCLC) by increasing long-term overall survival. Although a diagnosis of NSCLC during pregnancy or the peripartum period is rare, ALK⁺ NSCLC accounts for 38% of NSCLC cases in women of childbearing age (18-45 years old). The younger age and prolonged survival of patients with ALK⁺ mNSCLC bring new challenges for lung cancer and obstetrics research, and raises questions related to pregnancy and family planning. The present study described normal fetal development and no obstetric complications in a patient infected with HIV diagnosed with ALK⁺ mNSCLC, who became pregnant during treatment with alectinib, a third-generation ALK inhibitor.

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.

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.

Safe and Effective Use of Imatinib to Treat Philadelphia Chromosome Positive Acute Lymphoblastic Leukemia During Pregnancy

Philadelphia chromosome positive (Ph+) B cell acute lymphoblastic leukemia (ALL) is extremely rare in pregnancy. Although the use of tyrosine kinase inhibitors (TKIs) has significantly improved outcomes of patients with Ph+ ALL, its use during pregnancy is not recommended due to the risk of fetal malformations. There are limited data on the use of TKIs during pregnancy and its long-term effects on the fetus. Within this context, we present a case of a 25-year-old woman diagnosed with Ph+ ALL during the third trimester and the safe and effective use of imatinib as treatment after failure of conventional chemotherapy.

Impact of chemotherapy during pregnancy on fetal growth

BACKGROUND

Chemotherapy crosses the placenta, however, it remains unclear to what extent it affects fetal growth. The current literature suggests up to 21% of the offspring of women receiving chemotherapy are small for gestational age (SGA, birth weight <10th percentile). Limiting research to birth weights only might misjudge fetal growth restriction (FGR) in this high-risk population with multiple risk factors for impaired fetal growth. Moreover, the role of the duration of chemotherapy and gestational age at initiation of chemotherapy in fetal growth is yet poorly understood.

OBJECTIVE

This retrospective cohort study evaluates fetal growth and neonatal birthweights in pregnant women receiving chemotherapy.

STUDY DESIGN

All pregnant patients, registered by the International Network of Cancer, Infertility and Pregnancy (INCIP), treated with chemotherapy with at least two ultrasounds reporting on fetal growth, were eligible for this study. Duration and gestational age at initiation of chemotherapy were our major determinants, followed by cancer type and stage, maternal characteristics (parity, BMI, ethnicity hypertension, and diabetes) and individual cytotoxic agents (anthracycline, taxanes, and platinum). Fetal growth outcomes were described using the following mutually exclusive groups (1) FGR, based on a Delphi consensus (2016); (2) "low risk SGA" (birth weight below the 10th percentile), but an estimated growth above the 10th percentile; (3) "fetal growth disturbance", which did not meet all FGR criteria; (4) "non-FGR". Obstetric and oncological characteristics were compared between the growth impaired groups and non-FGR group. We calculated estimated fetal weight (EFW) according to Hadlock's formula (1991) and birth weight percentile according to Nicolaides (2018). We used univariable and multivariable regression, and linear mixed effect models to investigate the effect of duration and gestational age at initiation of chemotherapy on birth weight, and fetal growth, respectively.

RESULTS

We included 201 patients, diagnosed with cancer between March 2000 and March 2020. Most patients were diagnosed with breast cancer (n = 132, 66%). Regimens included anthracyclines (n = 121, 60%), (anthracyclines and) taxanes (n = 45, 22%) and platinum (n = 35, 17%). Fetal growth abnormalities were detected in 75 pregnancies: 43 (21%) FGR, 10 (5%) low risk SGA and 22 (8.5%) fetal growth disturbance. Chemotherapy prior to 20 weeks of gestation (47% vs. 25%, p = .04) and poor maternal gestational weight gain (median percentile 15 (range 0-97) vs. 8 (0-84), p = .03) were more frequent in the FGR group compared to the non-FGR group, whereas no difference was seen for specific chemotherapy or cancer types. Univariable regression identified gestational weight gain, hypertension, systemic disease, parity, neonatal sex and maternal BMI as confounders for birth weight percentiles. Multivariable regression revealed that each additional week of chemotherapy was associated with lower birth weight percentiles (-1.06; 95%CI -2.01; -0.04; p = .04), and that later initiation of chemotherapy was associated with an increase in birth weight percentile (1.10 per week; 95%CI 0.26; 1.95; p = .01). Each additional week of chemotherapy was associated with lower EFW and abdominal circumference (AC) percentiles (-1.77; 95%CI -2.21; -1.34, p < .001; -1.64; 95%CI -1.96; -1.32, p < .001, respectively).

CONCLUSIONS

This study demonstrates that FGR is common after chemotherapy in pregnancy, and that the duration of chemotherapy has a negative impact. Sonographic follow-up of fetal growth and well-being is recommended.

Long-Term Morbidity and Mortality in Children After In Utero Exposure to Maternal Cancer

PURPOSE

In utero exposure to maternal cancer and cancer treatment might influence the child's short- and long-term health and development. The objective of the study was to investigate short- and long-term somatic and psychiatric outcomes in children exposed to maternal cancer in utero.

METHODS

This nationwide cohort study identified all liveborn children in Denmark between January 1978 and December 2018. Exposure was defined as maternal cancer diagnosis during pregnancy, and in a subgroup analysis, exposure to chemotherapy in utero. The main outcomes of interest were overall mortality, somatic diagnoses, and psychiatric diagnoses identified in the National Health Registers. Follow-up started at birth and ended at an event, death, emigration, or end of 2018. Hazard ratios of end points adjusted for potential confounders were estimated using Cox regression analysis.

RESULTS

Of 2,526,163 included liveborn children, 690 (0.03%) were exposed to maternal cancer in utero. Compared with unexposed fetuses, children exposed in utero had no higher overall mortality, adjusted hazard ratio 0.8 (95% CI, 0.4 to 1.5), nor increased risk of congenital malformations, overall somatic or psychiatric disease. During the period 2002-2018, of 378 (0.03%) children exposed to cancer in utero, 42 (12.5%) were exposed to chemotherapy. Among these 42 children, in utero exposure to chemotherapy was not associated with selected somatic diseases nor to congenital malformations when compared with in utero exposure to maternal cancer without chemotherapy.

CONCLUSION

Overall, findings did not indicate excess risk of mortality or severe morbidity among children exposed to cancer in utero. Fetal exposure to chemotherapy was not associated with adverse health outcomes in childhood.

Women at heart: Introducing gender cardio-oncology

As cardio-oncology imposed itself as the reference specialty for a comprehensive cardiovascular approach to all patients with cancer, a more specific and careful cardiac evaluation of women entering their journey into cancer care is needed. Gender medicine refers to the study of how sex-based biological and gender-based socioeconomic and cultural differences influence people's health. Gender-related aspects could account for differences in the development, progression, and clinical signs of diseases as well as in the treatment of adverse events. Gender also accounts for major differences in access to healthcare. As for medicine and healthcare in general, gender-related characteristics have gained significance in cardio-oncology and should no longer be neglected in both clinical practice and research. We aimed to review the most relevant cardiovascular issues in women related to the cardio-oncology approach to offer a specific gender-related point of view for clinicians involved in the care process for both cancer and cardiovascular disease.

[Cancer during pregnancy: Proposal of a clinical care pathway based on a regional cohort]

OBJECTIVES

Cancer during pregnancy affects 1 in 1000 pregnancies. This situation requires multidisciplinary team, however there is no care pathway dedicated to these patients. The main objective was to describe oncological, obstetrical, and neonatal care through a regional inventory. Our secondary objective was to define a regional "cancer and pregnancy" care pathway.

MATERIAL AND METHOD

We carried out an observational, retrospective study from 2013 to 2019 including 48 women (all cancer types) from 2013 to 2019 in Occitania. Then, we defined an "optimal care pathway" and we assessed whether it was respected in the breast cancer subgroup of our cohort.

RESULTS

Live births occurred in 79% of the women included. Maternal treatment was initiated during pregnancy for 67% of our population (44% chemotherapy). The most frequent pregnancy complication was preterm delivery (39%), mainly iatrogenic (86.6%). No patient in the group of breast cancer benefited from all of the ten criteria of the "optimal care pathway" that we proposed.

CONCLUSIONS

A coordinated regional care pathway seems necessary to optimize communication between the healthcare providers (oncologists, gynecologists and multidisciplinary prenatal diagnosis centers, pharmacologists, pediatricians, psychologists, and general practitioners). This study identifies weaknesses in the management of women with cancer during pregnancy and suggests regional improvement opportunities.

Effect of Two-Port Laparoscopic Surgery on Pregnancy Outcomes of Patients with Concurrent Adnexal Masses

Adnexal masses are common in pregnancy, with 2–10% of pregnancies presenting with an ovarian mass and approximately 1–6% of these masses being malignant. For suspected malignancy or masses with symptoms, surgery must be performed as early as possible. We retrospectively investigated the effect of two-port laparoscopic surgery on the outcomes of patients with concurrent adnexal masses between 2012 and 2019 (including large mucinous tumor, large teratoma, serous borderline tumor, and heterotopic pregnancy). Laparoscopic right partial oophorectomy was performed for a 27 cm ovarian mucinous tumor at a gestational age (GA) of 21 weeks, laparoscopic right oophorocystectomy for an 18 cm teratoma at a GA of 10 weeks, and laparoscopic left salpingo-oophorectomy for a 7 cm serous borderline tumor at a GA of 7 weeks after ultrasonographic confirmation of an intrauterine gestational sac with a fetal heartbeat. Laparoscopic excision of a tubal pregnancy was performed in a heterotopic pregnancy at a GA of 12 weeks with massive internal bleeding. Laparoscopic surgery is easier and safe to perform during early pregnancy because a smaller uterus allows for superior visualization. All of these patients had optimal postoperative recovery and normal spontaneous delivery at term. We discussed several aspects of treatment and delivery, namely treatment option (expectant management or surgery), surgery timing (early or advanced pregnancy), surgery type (laparoscopy or laparotomy), and delivery route (normal spontaneous delivery or cesarean section), in patients with concurrent adnexal tumors and their effects on pregnancy outcomes.

Fast-growing immature ovarian teratoma during pregnancy: a case report and a review of the literature

Background

Immature ovarian teratoma is one of the three common malignant ovarian germ cell tumors. However, immature ovarian teratoma in pregnancy is very rare. Due to the rare occurrence, there is little evidence regarding its diagnosis, optimal management, and prognosis. Hence, we present a case of immature teratoma diagnosed during pregnancy, and analyze its clinicopathological features, management and prognosis.

Case presentation

A 28-year-old woman underwent a sonographic examination revealed no abnormality in the bilateral adnexal area before 29 weeks gestational age (WGA). At 29 WGA, ultrasound demonstrated a 9.7 × 8.5 × 6.4 cm complex structure in the left adnexal area. At 30 WGA, repeated ultrasound revealed rapid growth of tumor mass, measuring 25.0 × 15.0 × 13.7 cm. An elective cesarean section combined with exploratory laparotomy was performed at 33 WGA. Intraoperative frozen pathological examination suggested left ovarian immature teratoma. Then, she underwent a complete staging surgery. Subsequently, the patient received 4 cycles of bleomycin-etoposide-cisplatin (BEP) chemotherapy. After 18 months of follow-up, there is no sign of tumor recurrence till now.

Conclusions

This case report suggests that the benefits and risks of timely treatment for patients and fetuses should be fully assessed by a multidisciplinary team. The early diagnosis, the timing of surgery and chemotherapy, the choice of chemotherapy for BEP will determine the prognosis. Surgery and combination chemotherapy with BEP play an important role in the treatment of immature teratomas in pregnancy, and could gain successful and satisfactory outcomes for mother and fetus.

Transplacental Passage and Fetal Effects of Antineoplastic Treatment during Pregnancy

Simple Summary

In this paper we perform an introduction about pregnancy-associated cancer (PAC) and transplacental passage of antineoplastic agents. Furthermore, we describe therapeutic use and potential toxic effects of chemotherapeutic drug (alkylating agents, antimetabolites agents, anthracyclines, topoisomerase inhibitors, antimitotic agents, actinomycin-D, bleomycin) and targeted agents during pregnancy. This manuscript may be a useful and practical guide for the management of PAC, which is a challenge for clinicians that have to consider alike maternal benefits and fetal potential risks correlated to the antineoplastic treatment.

Abstract

The incidence of PAC is relatively infrequent among pregnant women. However, it has gradually increased in recent years, becoming a challenging area for clinicians that should take into account in the same way maternal benefits and fetal potential risks correlated to the antineoplastic treatment. None of the antineoplastic drugs is completely risk-free during the pregnancy, the timing of exposure and transplacental transfer properties influence the toxicity of the fetus. Despite the lack of guidelines about the management of PAC, several studies have described the use and the potential fetal and neonatal adverse events of antineoplastic drugs during pregnancy. We provide a review of the available literature about the transplacental passage and fetal effects of chemotherapy and targeted agents, to guide the clinicians in the most appropriate choices for the management of PAC.

Trends in Pregnancy-Associated Cervical Cancer in Japan between 2012 and 2017: A Multicenter Survey

Large-scale data on maternal and neonatal outcomes of pregnancy-associated cervical cancer in Japan are scarce, and treatment strategies have not been established. This multicenter retrospective observational study investigated clinical features and trends in pregnancy-associated cervical cancer treatments at 523 hospitals in Japan. We included cervical cancer cases that were histologically diagnosed (between 1 January 2012, and 31 December 2017), and their clinical information was retrospectively collected. Of 40 patients diagnosed with pregnancy-associated cervical cancer at ≥22 gestational weeks, 34 (85.0%) were carefully followed until delivery without intervention. Of 163 diagnosed at <22 gestational weeks, 111 continued and 52 terminated their pregnancy. Ninety patients with stage IB1 disease had various treatment options, including termination of pregnancy. The 59 stage IB1 patients who continued their pregnancy were categorized by the primary treatment into strict follow-up, conization, trachelectomy, and neoadjuvant chemotherapy groups, with no significant differences in progression-free or overall survival. The birth weight percentile at delivery was smaller in the neoadjuvant chemotherapy group than in the strict follow-up group (p = 0.029). Full-term delivery rate was relatively higher in the trachelectomy group (35%) than in the other groups. Treatment decisions for pregnancy-associated cervical cancer are needed after estimating the stage, considering both maternal and fetal benefits.

Ten-year experience of a national multidisciplinary tumour board for cancer and pregnancy in the Netherlands

BACKGROUND

Most physicians encounter pregnant women with cancer incidentally, leading to a lack of expertise or confidence to inform and treat these patients based on the most recent guidelines and expert opinions. In the Netherlands, a national multidisciplinary tumour board for cancer, infertility and pregnancy (CIP-MDT) was founded in December 2012, including 35 specialists from a variety of disciplines. This study evaluates the frequency of consultation of the CIP-MDT, the types of questions asked and the satisfaction of consulting physicians with its existence.

METHODOLOGY

Of all requests to the CIP-MDT between December 2012 and June 2021, tumour type, stage, gestational age at diagnosis and recommendations were collected and analysed. For evaluating the methods of the CIP-MDT, a survey with questions regarding experiences with the CIP-MDT and its impact on treatment decisions was sent out to physicians that consulted the CIP-MDT.

RESULTS

Recommendations (n = 213) concerned preferred and safest options for imaging, treatment options during pregnancy, possible effects on the child and fertility preserving options. Most frequently discussed malignancies were breast cancer (n = 66), cervical cancer (n = 34), haematological malignancies (n = 32) and melanoma (n = 21). The questionnaire was completed by 54% of the physicians (n = 50). Satisfaction with the recommendations of the CIP-MDT was high, and 94% of the physicians informed their patients about consulting the CIP-MDT and felt supported by the received recommendations.

DISCUSSION

The national Dutch CIP-MDT contributes to a high level of satisfaction among physicians requesting advice. Further research should be executed to confirm that a CIP-MDT improves the outcomes for pregnant women and their children.

Update on Pregnancy Following Breast Cancer Diagnosis and Treatment

ABSTRACT

Survivorship has become a crucial component in breast cancer care. For women who have not completed their family planning, conceiving at the end of anticancer treatments should not be discouraged but might be challenging. Oncofertility counseling should be offered at the time of diagnosis to all patients, in order to inform them about the potential treatment-induced gonadotoxicity as well as the available strategies for fertility preservation, thus allowing to increase the chances of a future pregnancy. This article reports an updated overview on the current state of the art on pregnancy in women with prior breast cancer diagnosis and treatment, with a main focus on the issues faced by patients with history of hormone receptor-positive disease and BRCA carriers.

Pregnancy outcomes related to the treatment of sarcomas with anthracyclines and/or ifosfamide during pregnancy

Background

Sarcomas are rare diagnoses but are seen with relative frequency in adolescents and young adults and thus can present in pregnancy. We sought to study the administration of anthracyclines and/or ifosfamide in pregnancy‐associated sarcomas.

Patients and Methods

We conducted a multi‐institutional retrospective study, identifying sarcoma patients who received anthracyclines and/or ifosfamide during pregnancy. Chart review identified variables related to demographics, cancer diagnosis, therapies, and outcome of the patient and fetus. Wilcoxon rank‐sum test compared two independent samples.

Results

We identified 13 patients at seven institutions with sarcoma who received anthracyclines and/or ifosfamide during pregnancy, including four bone sarcomas and nine soft tissue sarcomas diagnosed at a mean gestational age of 16.7 ± 5.9 weeks. Only nine patients had live births (9/13, 69.2%), with mean gestational age of 30.8 ± 3.8 weeks at delivery. The four patients with pregnancy loss all received both doxorubicin and ifosfamide, with chemotherapy initiated at 15.5 weeks as compared with 21.3 weeks for those patients with live births (p = 0.016).

Conclusion

In this multi‐institutional study of sarcoma chemotherapy regimens administered during pregnancy, we found a high rate of fetal demise that was seen only in patients receiving both doxorubicin and ifosfamide and statistically more likely with chemotherapy initiation earlier in the second trimester. While limited by a small sample size, our study represents the largest study of sarcoma patients that received anthracyclines and/or ifosfamide in pregnancy thus far reported and supports development of an international registry to study concerns raised by our study.

Prognosis of triple-negative breast cancer associated with pregnancy: A propensity score-matched analysis from the French CALG (Cancer Associé à la Grossesse) network

Introduction

Triple-negative (TN) breast cancer represents one third of pregnancy-associated breast cancers (PABC). The aims of the current study were to describe oncological and obstetrical outcomes of patients with TN-PABC and to compare their prognosis with TN-non-PABC patients using a propensity score.

Materials and methods

Between January 2005 and December 2020, data of patients with histologically proven TN-PABC were collected and compared with data of TN-non-PABC patients under the age of 46 years diagnosed during the same period using a propensity score (PS).

Results

After PS matching (tumor size and lymph node involvement),there were 59 patients in each group. The median follow-up was 14 months (IQR 4.8–40.1) for the TN-PABC group and 60 months (IQR 30.7–101.4) for the TN-non-PABC group. Eight recurrences occurred in the TN-PABC group and 10 in the TN-non-PABC group (adjusted OR (AOR) = 0.60 (0.21–1.60), HR (Cox adjusted model- AHR) = 1.25 (0.53–2.94)). Two patients died in the TN-PABC group, and six in the TN-non-PABC group with an AOR = 0.23 (0.03–1.01) and an AHR = 0.58 (0.12–2.69). All the patients diagnosed during the second (n = 17) and third trimesters (n = 28) continued their pregnancies, with a median term at delivery of 38 WG (IQR 36–39). All patients gave birth to healthy newborns.

Conclusion

Although the TN subtype is associated with poor prognosis in pregnant patients due to advanced stage at diagnosis and high lymph node involvement, our PS-matched case-control study showed that pregnancy per se does not worsen the prognosis in terms of recurrence-free and overall survival.

•

Triple-negative breast cancer are associated with poor prognosis.

•

Breast cancers occurring during pregnancy differ from those occurring in the post-partum period.

•

Pregnancy per se does not worsen the prognosis in triple-negative breast cancer.

Maternal and Fetal Outcomes of Acute Leukemia in Pregnancy: A Retrospective Study of 52 Patients

Acute leukemia during pregnancy (P-AL) is a rare disease with limited data regarding the management and outcomes of mothers and fetuses. We retrospectively analyzed the characteristics, pregnancy outcomes and maternal and neonatal prognoses of 52 patients with P-AL collected from January 2013 to December 2020 in our center. Seventeen (32.7%) patients received chemotherapy during pregnancy (exposed cohort), while 35 (67.3%) received chemotherapy after abortion/delivery (nonexposed cohort). Twenty-six (50.0%) pregnancies ended with abortion, and 26 (50.0%) babies were born through spontaneous delivery or cesarean section. Seven infants (26.9%) were born in the exposed cohort, while 19 infants (73.1%) were born in the nonexposed cohort. Fetuses in the exposed cohort had lower gestational ages (P=0.030) and birth weights (P=0.049). Considering the safety of the fetus, seven patients in the exposed cohort received low-dose chemotherapy, one patient received all-trans retinoic acid (ATRA) and one patient only received corticosteroids as induction therapy. Patients received low-dose chemotherapy as induction therapy had a lower complete remission (CR) rate (P=0.041), and more patients in this group received HSCT (P=0.010) than patients received intensive chemotherapy. Patients who delayed chemotherapy in the nonexposed cohort experienced a trend toward a higher mortality rate than patients who received timely chemotherapy (P=0.191). The CR (P = 0.488), OS (P=0.655), and DFS (P=0.453) were similar between the exposed and nonexposed cohorts. Overall, the 4-year overall survival (OS) and disease-free survival (DFS) rates were estimated at 49.1% and 57.8%, respectively. All newborns were living, without deformities, or developmental and intellectual disabilities. Our study indicated that P-AL patients in the first trimester might tend to receive chemotherapy after abortion. Both the status of disease and patients’ willingness should be taken into consideration when clinicians were planning treatment strategies in the second or third trimester. Low-dose or delayed chemotherapy might decrease the efficacy of induction therapy and survival rate of patients, but HSCT could improve the prognosis.

Cancer and Pregnancy: National Trends

OBJECTIVE

Cancer and pregnancy are likely increasing; however, updated estimates are needed to optimally address the unique needs of this patient population. The study aims to estimate the prevalence of cancer and cancer survivorship at delivery, to test the change in odds of cancer and cancer survivorship at delivery over the 10-year period, and to compare medical conditions, serious events, and obstetric complications between pregnancies with and without cancer at delivery.

STUDY DESIGN

We conducted a retrospective analysis of the National Inpatient Sample (NIS), the largest all-payer inpatient health database in the United States. We identified delivery admissions from 2004 to 2013 with a concurrent diagnosis of cancer using International Classification of Disease, ninth revision (ICD-9) codes. Multivariable logistic regression was used to test the change in prevalence of concurrent cancer, cancer survivorship, and pregnancy and to compare outcomes between deliveries with and without cancer. All analyses were adjusted for NIS-provided population weights and strata.

RESULTS

During the study period, the NIS represented a national estimate of 40,855,208 deliveries. The odds of cancer increased from 3.41/10,000 deliveries in 2004 to 4.33/10,000 in 2013. This trend was statistically significant, including after adjustment for maternal age (adjusted odds ratio [aOR] = 1.03 [95% confidence interval (CI): 1.01-1.04]). Cancer survivorship at delivery increased significantly (aOR = 1.07 [95% CI: 1.06-1.08]). Women with cancer more often experienced one or more of the following: death, ventilation, cardiac arrest, sepsis, or acute respiratory or renal failure during delivery (aOR for composite outcome 10.7 [95% CI: 6.6-17.2]), even after adjustment in a multivariable logistic regression model.

CONCLUSION

The odds of cancer and cancer survivorship at delivery increased from 2004 to 2013, independent of maternal age. Women with cancer were more likely to experience medical or obstetric complications during their delivery compared with women without cancer. These findings highlight the importance of obstetric and oncologic clinical and research collaboration to improve patient care.

KEY POINTS

· The odds of cancer at delivery increased.. · Women with cancer may have delivery complications.. · Cancer survivorship at delivery increased..

Desmoplastic Small Round Cell Tumor in a Pregnant Woman: A Case Report and Literature Review

Background: Desmoplastic small round cell tumor (DSRCT) is an aggressive malignant tumor commonly found in young men; most occurs in the abdominal cavity. Here we conducted an in-depth analysis of a pregnant patient in our hospital and explored all the case information in the literature on small round cell carcinoma of women. Case presentation: A 27-year-old pregnant woman underwent tumor resection in our hospital at 29 weeks gestational age for a large progressive shoulder lump. The postoperative pathology showed that the mass was a DSRCT. Genetic testing found no fusion gene. At 36 weeks gestation, a painful mass was found in the breast and proved to be a metastatic focus of the desmoplastic small round cell tumor. Twenty days after a successful cesarean section at 40 weeks gestation, she received the VAC-IE chemotherapy regimen, successfully completed the first course, but when awaiting the next chemotherapy, unfortunately, the patient died during follow-up due to tumor recurrence and metastasis. Conclusion: The treatment of DSRCT in pregnant women requires a multidisciplinary consultation, and the treatment and examination during pregnancy are subject to many constraints, which may have a negative impact on the patient's prognosis. Also, a review of the literature found that there is still no standard treatment protocol for DSRCT, and its prognosis in female patients is independent of age and tissue origin.

Acute leukemia in pregnancy: a single institutional experience with 21 cases at 10 years and a review of the literature

INTRODUCTION

Acute leukemia (AL) occurring in pregnancy is extremely rare, and its treatment is a clinical dilemma.

METHODS

We retrospectively reviewed the medical records of our hospital from 2010 to 2019.

RESULTS

Twenty-one patients were diagnosed with AL during pregnancy. Of whom, eighteen had acute myeloid leukemia, and 3 had acute lymphoblastic leukemia. Six, eight and seven patients were diagnosed during the first, second, and third trimester, respectively. Six of the 21 patients experienced therapeutic abortion and 1 had spontaneous abortion, whereas 9 gave birth to healthy babies (4 through vaginal deliveries and 5 with Caesarean sections). Four babies had been exposed to chemotherapeutic agents, but no congenital malformations were observed. Sixteen patients received chemotherapy, while 4 patients died before chemotherapy and one was discharged after refusing chemotherapy. The complete remission rate of the 10 patients who began chemotherapy immediately after diagnosis was 80%, compared with 66.7% in the 6 patients who started chemotherapy after abortion or delivery. Three remain alive.

CONCLUSIONS

In general, initiation of chemotherapy as early as possible may increase the CR rate. Combined with literature data, we proposed that, for patients diagnosed in early and late stages of pregnancy (>30 weeks), elective termination or induced delivery before chemotherapy may be a good choice for better maternal (and fetal) outcome.KEY MESSAGESAcute leukaemia diagnosed in pregnancy is extremely rare, and its treatment is a clinical dilemma.In general, initiation of chemotherapy as early as possible may increase the CR rate.For patients who are diagnosed in the first trimester or late stage of pregnancy (>30 weeks), elective termination or induced delivery before starting chemotherapy may be a good choice for better maternal (and fetal) outcome.

Clinical Decision Making in the Management of Breast Cancer Diagnosed During Pregnancy: A Review and Case Series Analysis

Purpose: To highlight the various options available for the management of breast cancer diagnosed during pregnancy by describing the investigations, treatment, and outcomes in relation to these women. Methods: This is a narrative review of the literature to describe the issues related to pregnancy and obstetric management in patients with breast cancer. It incorporates a description of six cases of women (aged 29-39 years) with a first-time diagnosis of breast cancer during pregnancy to illustrate a number of issues that need to be considered during different trimesters. Results: Of the six cases, two were diagnosed in each pregnancy trimester. A painless breast mass was the presenting symptom in five cases (83%). In all cases, breast ultrasound was the primary diagnostic imaging procedure. Chest X-ray was performed in 3 (50%) and computed tomography in 2 (33%). A core needle biopsy was performed in all cases, and sentinel lymph node biopsy in 3 (50%) cases. Four women had grade 3 tumor; five had estrogen receptor-positive tumors. Four women had breast surgery during pregnancy. Five women gave birth after the induction of labor and/or cesarean section. In all six cases, a multidisciplinary team was involved in the delivery of health care. Conclusion: Regular breast examinations are needed for all pregnant woman during prenatal visits. Breast ultrasonography should be offered if a breast lump or other symptoms are detected. Breast surgery can be safely performed during all pregnancy trimesters, and some systemic therapeutic agents can be administered safely in the second and third trimesters.

In-Hospital Complications in Pregnant Women With Current or Historical Cancer Diagnoses

OBJECTIVE

To assess the temporal trends, characteristics and comorbidities, and in-hospital cardiovascular and obstetric complications and outcomes of pregnant women with current or historical cancer diagnosis at the time of admission for delivery.

METHODS

We analyzed delivery hospitalizations with or without current or historical cancer between January 1, 2004, and December 31, 2014, from the US National Inpatient Sample database.

RESULTS

We included 43,132,097 delivery hospitalizations with no cancer, 39,118 with current cancer, and 67,336 with historical diagnosis of cancer. The 5 most common types of current cancer were hematologic, thyroid, cervical, skin, and breast cancer. Women with current and historical cancer were older (29 years and 32 years vs 27 years) and incurred higher hospital costs ($4131 and $4078 vs $3521) compared with women without cancer. Most of the cancer types were associated with preterm birth (hematologic: adjusted odds ratio [aOR], 1.48 [95% CI, 1.35 to 1.62]; cervical: aOR, 1.47 [95% CI, 1.32 to 1.63]; breast: aOR, 1.93 [95% CI, 1.72 to 2.16]). Current hematologic cancer was associated with the highest risk of peripartum cardiomyopathy (aOR, 12.19 [95% CI, 7.75 to 19.19]), all-cause mortality (aOR, 6.50 [95% CI, 2.22 to 19.07]), arrhythmia (aOR, 3.82 [95% CI, 2.04 to 7.15]), and postpartum hemorrhage (aOR, 1.31 [95% CI, 1.11 to 1.54]). Having a current or historical cancer diagnosis did not confer additional risk for stillbirth; however, metastases increased the risk of maternal mortality and preterm birth.

CONCLUSION

Women with a current or historical diagnosis of cancer at delivery have more comorbidities compared with women without cancer. Clinicians should communicate the risks of multisystem complications to these complex patients.

Philadelphia chromosome-negative myeloproliferative neoplasms in younger adults: A critical discussion of unmet medical needs, with a focus on pregnancy

Myeloproliferative neoplasms (MPN) are traditionally regarded as a disease of older adults, though a not negligible fraction of cases occurs at a younger age, including women of childbearing potential. MPN in younger patients, indeed, offer several challenges for the clinical hematologist, that goes from difficulties in reaching a timely and accurate diagnosis to a peculiar thrombotic risk, with a relatively high incidence of thromboses in unusual sites (as the splanchnic veins or the cerebral ones). Moreover, the issue of pregnancy is recently gaining more attention as maternal age is rising and molecular screening are widely implemented, leading to a better recognition of these cases, both before and during pregnancy. In the present work we aim at discussing four clinical topic that we identified as areas of uncertainty or true unmet medical needs in the management of younger patients with MPN, with a particular focus on the topic of pregnancy. For each of these topics, we critically reviewed the available evidence that support treatment decisions, though acknowledging that recommendations in this field are mostly based on expert opinion or derived from guidelines of other clinical conditions that share with MPN a high vascular risk, as antiphospholipid syndrome. Taking into consideration both the lack of evidence-based data and the clinical heterogeneity of MPN, we support an individualized strategy of counseling and management for both young patients and for expectant mother with MPN.
