RESUMEN

BACKGROUND: Breast cancer (BC) is the most common malignancy in women of reproductive age. This study sought to explore the postcancer conception and pregnancy experience of young BC survivors to inform counseling. METHODS: In the Young Women's Breast Cancer Study (NCT01468246), a multicenter, prospective cohort, participants diagnosed at age ≤40 years with stage 0-III BC who reported ≥1 postdiagnosis live birth were sent an investigator-developed survey. RESULTS: Of 119 eligible women, 94 (79%) completed the survey. Median age at diagnosis was 32 years (range, 17-40) and at first postdiagnosis delivery was 38 years (range, 29-47). Most had stage I or II (77%) and HR+ (78%) BC; 51% were nulligravida at diagnosis. After BC treatment, most (62%) conceived naturally, though 38% used assisted reproductive technology, 74% of whom first attempted natural conception for a median of 9 months (range, 2-48). Among women with a known inherited pathogenic variant (n = 20), two underwent preimplantation genetic testing. Of 59 women on endocrine therapy before pregnancy, 26% did not resume treatment. Hypertensive disorders of pregnancy (20%) was the most common obstetrical condition. Nine percent of newborns required neonatal intensive care unit admission and 9% had low birth weight. CONCLUSION: Among women with live births after BC treatment, most conceived naturally and having a history of BC did not appear to negatively impact pregnancy complications, though the high rate of hypertensive disorders of pregnancy warrants further investigation. The prolonged period of attempting natural conception for some survivors suggests the potential need for improved understanding and counseling surrounding family planning goals after BC.

RESUMEN

PURPOSE: To review the literature exploring endometrial cancer (EC) risk among surgical candidates with germline BRCA1/2 pathogenic variants (PVs) to guide decisions around risk-reducing (rr) hysterectomy in this population. DESIGN: A comprehensive review was conducted of the current literature that influences clinical practice and informs expert consensus. We present our understanding of EC risk among BRCA1/2 PV carriers, the risk-modifying factors specific to this patient population, and the available research technology that may guide clinical practice in the future. Limitations of the existing literature are outlined. RESULTS: Patients with BRCA1/2 PVs, those with a personal history of tamoxifen use, those who desire long-term hormone replacement therapy, and/or have an elevated BMI are at higher risk of EC, primarily endometrioid EC and/or uterine papillary serous carcinoma, and may benefit from rr-hysterectomy. Although prescriptive clinical guidelines specific to BRCA1/2 PV carriers could inform decisions around rr-hysterectomy, limitations of the current literature prevent more definitive guidance at this time. A large population-based study of a contemporary cohort of BRCA1/2 PV carriers with lifetime follow-up compared with cancer-gene negative controls would advance this topic and facilitate care decisions. CONCLUSION: This review validates a potential role for rr-hysterectomy to address EC risk among surgical candidates with BRCA1/2 PVs. Evidence-based clinical guidelines for rr-hysterectomy in BRCA1/2 PV carriers are essential to ensure equitable access to this preventive measure, supporting insurance coverage for patients with either BRCA1 or BRCA2 PVs to pursue rr-hysterectomy. Overall, this review highlights the complexity of EC risk in BRCA1/2 PV carriers and offers a comprehensive framework to shared decision making to inform rr-hysterectomy for BRCA1/2 PV carriers.

RESUMEN

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.

RESUMEN

OBJECTIVE: Despite greater female than male-identifying Canadian medical graduates, women continued to be underrepresented in surgical specialties. The aim of this study was to explore the role of lifestyle challenges and gender-specific considerations in career selection for first-year medical students following early exposure to surgery through an immersive surgical program. DESIGN: A single institution, qualitative study consisting of structured focus groups before and after completion of a 2-week surgical program was used to explore medical student perceptions of surgery. The program consisted of shadowing, surgeon-led talks, and surgical skills workshops in all direct-entry surgical specialties within the Department of Surgery at the University of Toronto. Six entry and exit interviews were conducted by 2 authors. Interviews were recorded, transcribed, and coded for thematic analysis. SETTING: Teaching hospitals affiliated with the University of Toronto, Canada PARTICIPANTS: Thirty first-year medical students with interest in surgery participated in the program and the focus groups. RESULTS: Four prominent themes emerged: gender imbalances in the work environment, the importance of female mentors, gender-specific challenges of parenting, and the importance of flexible work hours for both male and female students. Greater exposure to female surgeons improved the outlook of medical students on work-life balance. Medical students are concerned with the challenges of pregnancy in a surgical profession. Both male and female students consider parenting, supportive partners, and flexibility of work hours in their career selection. CONCLUSION: This study demonstrates the prevalence of gender bias in surgical specialties, raising gender-specific challenges that impact career selection for first-year medical students. In an effort to address these perceptions, this study supports efforts to implement formalized mentorship programs for women in surgery early in medical education. Furthermore, concerns surrounding childbearing further support the need for well-established parental leave policies in the Canadian postgraduate medical education system.

RESUMEN

There are still children with cleft lip and/or palate (CLP) in low-resource areas who face social rejection. This stigma disadvantages children in education, employment, marriage, and community, and is exacerbated by barriers to care. Our study objective was to conduct a systematic review of the impact of social stigma of CLP for children in low-resource areas. We followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A systematic search was conducted of 3 databases: Ovid Embase, Ovid Medline, and the African Journal Online from 2000 to October 5 2018. Common themes were identified using a grounded theory approach and quantitatively summarized. The Joanna Briggs Institute criteria were used to evaluate the risk-of-bias assessments. Four hundred seventy-seven articles were screened; 15 articles were included that focused on the impact of social stigma on CLP in low-resource areas. This was limited to English articles. The majority of studies originated in Nigeria or India. Themes were reported as follows: societal beliefs (n = 9; 60%), social impact (n = 7; 46%), marriage (n = 7; 46%), education (n = 6; 40%), employment (n = 5; 33%), and psychological distress (n = 3; 20%). Causes include the effect of "God's will," supernatural forces, evil spirits or ancestral spirits, exposure to an eclipse, black magic, or a contagion. Further, children with CLP may not be worth a full name or considered human and killed. Awareness of the impact of social stigma for children with CLP in low-resource areas generates support toward national education and awareness in low-resource areas.

RESUMEN

PROBLEM: A predicted shortage of surgeons and attrition among surgical residents has highlighted the need to attract well-suited medical students to surgical specialties. Literature suggests that early exposure may increase interest by addressing misconceptions and allowing students more time to make an informed career decision. APPROACH: The Surgical Exploration and Discovery (SEAD) program was created in 2012 with the goal of providing medical students with comprehensive and multifaceted exposure to surgical specialties to develop their knowledge and skills, and in turn positively influence their interest in pursuing a surgical career. The purpose of this innovation report is to describe the challenges, successes, and evolution of the SEAD program. OUTCOMES: Since its inception, SEAD has expanded to include 5 North American institutions and has educated nearly 400 participants in 5 y. Through a replication strategy, SEAD has maintained its basic curriculum, while accommodating the constraints and innovative approaches unique to each institution. Short-term results have demonstrated improved knowledge of curricular objectives, student perception of significant value of the program, and the generation of interest in a career in surgery. CONCLUSIONS: Future directions include the evaluation of long-term impact on pursuing a career in surgery and continuing further expansion using the current replication model, while maintaining a high-quality surgical education program.

RESUMEN

Determination of the material properties of soft tissue is a growing area of interest that aids in the development of new surgical tools and surgical simulators. This study first aims to develop a robot-operated tissue testing system for determination of tissue cutting forces. Second, this system was used to ascertain the cutting properties of the hard and soft palate mucosa and soft palate musculature for the purpose of developing a robotic instrument for cleft palate surgery and a cleft-specific surgical simulator. The palate tissue was cut with a 15 blade mounted to the robot with varying angles (30°, 60°, 90°) and speeds (1.5, 2.5, 3.5 cm/s) of cutting to imitate typical operative tasks. The cutting force range for hard palate mucosa, soft palate mucosa and soft palate muscle were 0.98-3.30, 0.34-1.74 and 0.71-2.71 N, respectively. The break-in force of the cut (i.e. force required for the blade to penetrate the tissue) is significantly impacted by the angle of the blade relative to the tissue rather than the cutting speed. Furthermore, the total surface area of the tissue in contact with the blade during the cut has a significant impact on the total force expended on the tissue.
