ABSTRACT

BACKGROUND: COVID-19 has placed demands on General Surgery residents, who are already at high risk of burnout. This study examined the pandemic's impact on burnout and wellness among General Surgery residents at a large training program. METHODS: General Surgery residents at our institution completed a survey focused on self-reported burnout, mental health, perceptions of wellness resources, and changes in activities during the pandemic. Burnout was measured using the Maslach Burnout Inventory (MBI). Unsupervised machine learning (k-means clustering) was used to identify profiles of burnout and comparisons between profiles were made. RESULTS: Of 82 eligible residents, 51 completed the survey (62% response rate). During COVID-19, 63% of residents had self-described burnout, 43% had depression, 18% acknowledged binge drinking/drug use, and 8% had anxiety. There were no significant differences from pre-pandemic levels (p all >.05). Few residents perceived available wellness resources as effective (6%). Based on MBI scores, the clustering analysis identified three clusters, characterized as "overextended", "engaged", and "ineffective". Engaged residents had the least concerning MBI scores and were significantly more likely to exercise, retain social contact during the pandemic, and had less self-reported anxiety or depression. Research residents were overrepresented in the ineffective cluster (46%), which had high rates of self-reported burnout (77%) and was characterized by the lowest personal accomplishment scores. Rates of self-reported burnout for overextended and engaged residents were 73% and 48%, respectively. CONCLUSION: Surgical residents have high rates of self-reported burnout and depression during the COVID-19 pandemic. Clusters of burnout may offer targets for individualized intervention.

ABSTRACT

PURPOSE: Some series have shown increased complications with extended nodal surgery and immediate breast reconstruction (IBR) with implants. We aim to explore complications associated with axillary dissection compared to sentinel lymph node biopsy at a population level. METHODS: American College of Surgeons National Surgical Quality Improvement Program participant user files from 2008-2018 were searched to create a cohort of female patients undergoing unilateral mastectomy with IBR and axillary surgery for non-metastatic breast cancer. Patients were classified as having sentinel lymph node biopsy (SLNB), axillary dissection (ALND), or sentinel lymph node biopsy and axillary dissection (SLNB + ALND). Baseline demographics were compared, and multivariable logistic regression was to assess for independent predictors of the primary outcome of 30-day morbidity. RESULTS: Between 2008 and 2018, 18,232 patients had mastectomy and IBR with axillary surgery; 12,632 patients underwent SLNB, 3727 had ALND and 1,873 underwent SLNB + ALND. Mean age of patients in the cohort was 52.5 (SD 11). There was no difference in 30-day morbidity between groups (SLNB: 4.3%, ALND: 4.9%, SLNB + ALND: 4.2%, p = 0.207). Multivariable regression showed that type of axillary surgery was not an independent predictor of 30-day complications (OR 0.78 (95% CI 0.52-1.15) for ALND, and OR 0.87 (95% CI 0.52-1.45) for ALND + SLNB vs SLNB alone). Significant independent predictors for complications were increased BMI (OR 1.06 (95%CI 1.04-1.08)) and increased operative time (OR 1.003 (95% CI 1.001-1.005)). CONCLUSIONS: ALND does not increase 30-day morbidity in patients undergoing IBR when compared to SLNB. This supports concurrent axillary dissection for IBR patients when indicated.

ABSTRACT

PURPOSE: Many women are being offered rapid genetic testing (RGT) for cancer predisposition genes, at the time of breast cancer diagnosis prior to surgery. The goal of this study was to determine if psychosocial functioning was affected in women receiving RGT for BRCA1 and BRCA2 at the time of breast cancer diagnosis. METHODS: Participants were women with invasive breast cancer diagnosed between 2013 and 2018, at four centres in Toronto, Canada. Eligible women were referred into the study by their surgeon at the time of diagnosis. Participants received pre-test genetic counselling and were offered RGT for BRCA1 and BRCA2. Standardized questionnaires (Impact of Event Scale and Hospital Anxiety and Depression Scale) were completed before genetic counselling, and follow-up questionnaires at one-week and one-year post-genetic test result disclosure (higher scores indicate higher symptoms). RESULTS: 1007 women had RGT; 60 women (6.0%) were found to have a BRCA1 or BRCA2 mutation, 80 women (7.9%) had a VUS, and 867 (86.1%) had a negative test result. At one-week post-testing, there were no differences in distress (p = 0.32), anxiety (p = 0.14), or depression (p = 0.42) between women with a BRCA1/2 mutation and those with a negative result. At one year, there were no differences in distress (p = 0.75) or anxiety (p = 0.13) between women with a BRCA1 or BRCA/2 mutation and those with a negative result. However, women with a BRCA1 or BRCA2 mutation had significantly lower depression scores compared to women with a negative result (p = 0.03). CONCLUSION: For women who have RGT for BRCA1 and BRCA2 at the time of breast cancer diagnosis, identifying a BRCA1 or BRCA2 mutation does not impair psychosocial functioning in the short or long term.

ABSTRACT

SummaryThe COVID-19 pandemic has substantially changed the practice of medicine with a shift to virtual clinical encounters, alternative management of surgical diseases owing to restrictions on elective operations, and physician redeployment to other medical services requiring coverage. These changes may limit opportunities for trainees to gain surgical expertise and have the potential to drastically affect postgraduate surgical education. However, the pandemic has also created a number of opportunities to navigate these challenges and enhance how surgical education is delivered. For example, there are now more learning opportunities available to trainees because of virtual educational sessions. We highlight some considerations in adapting postgraduate surgical training to achieve competency in the CanMEDS roles in the COVID-19 era.

ABSTRACT

Background: The transition from surgical residency to independent practice is a challenging period that has not been well studied. Methods: An email invitation to complete a 55-item survey and the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) was sent to early career general surgeons across Canada. The chi-square test or Fisher's exact test was used to compare demographic and survey characteristics with burnout. Multivariable logistic regression was performed. Results: Of the 586 surgeons contacted, 88 responded (15%); 51/88 surgeons (58.0%) were classified as burnt out according to the MBI-HSS. Most surgeons (68.2%) were not confident in their abilities to handle the business aspect of practice. The majority (60.2%) believed that a transition to independent practice program would be beneficial to recent surgical graduates. Conclusions: Our data showed high prevalence of burnout among recently graduated general surgeons across Canada. Further, respondents were not confident in their managerial and administrative skills required to run a successful independent practice.

ABSTRACT

There have been recent reports in the breast imaging literature of unilateral axillary lymphadenopathy following COVID-19 vaccination. It is unclear whether the reactive lymphadenopathy may impact the sentinel lymph node biopsy procedure. In this article, we provide guidelines regarding the timing of the COVID-19 vaccine and breast cancer surgery which were formulated after a review of the available literature and in consultation with infectious disease specialists.

ABSTRACT

PURPOSE: Many women with early-onset breast cancer experience adverse psychological sequelae which impact on their quality of life. We sought to correlate levels of anxiety and cancer-related distress in women with breast cancer shortly after surgery and one year after treatment with the estimated risk of death. METHODS: We studied 596 women with Stage I to III breast cancer. For each woman we estimated the five-year risk of death based on SEER data from 2010 to 2019. For each woman we measured anxiety and cancer-related distress levels shortly after surgery and one year later. RESULTS: The mean estimated five-year survival was 95%. At one week post-surgery, 59% of women had a clinically significant level of anxiety and 74% had a clinically significant level of cancer-related distress. There was no correlation between the objective risk of death and the level of anxiety or distress, at one week or at one year. CONCLUSIONS: Many women diagnosed with early-stage breast cancers experience significant levels of anxiety and distress. The emotional response to a breast cancer diagnosis is not related to the risk of death per se and other factors should be explored.

ABSTRACT

INTRODUCTION: Rates of bilateral mastectomy are rising in women with unilateral, nonhereditary breast cancer. We aim to characterize how psychosocial outcomes evolve after breast cancer surgery. PATIENTS AND METHODS: We performed a prospective cohort study of women with unilateral, sporadic stage 0-III breast cancer at University Health Network in Toronto, Canada between 2014 and 2017. Women completed validated psychosocial questionnaires (BREAST-Q, Impact of Event Scale, Hospital Anxiety & Depression Scale) preoperatively, and at 6 and 12 months following surgery. Change in psychosocial scores was assessed between surgical groups using linear mixed models, controlling for age, stage, and adjuvant treatments. P < .05 were significant. RESULTS: A total of 475 women underwent unilateral lumpectomy (42.5%), unilateral mastectomy (38.3%), and bilateral mastectomy (19.2%). There was a significant interaction (P < .0001) between procedure and time for breast satisfaction, psychosocial and physical well-being. Women having unilateral lumpectomy had higher breast satisfaction and psychosocial well-being scores at 6 and 12 months after surgery compared with either unilateral or bilateral mastectomy, with no difference between the latter two groups. Physical well-being declined in all groups over time; scores were not better in women having bilateral mastectomy. While sexual well-being scores remained stable in the unilateral lumpectomy group, scores declined similarly in both unilateral and bilateral mastectomy groups over time. Cancer-related distress, anxiety, and depression scores declined significantly after surgery, regardless of surgical procedure (P < .001). CONCLUSIONS: Psychosocial outcomes are not improved with contralateral prophylactic mastectomy in women with unilateral breast cancer. Our data may inform women considering contralateral prophylactic mastectomy.

ABSTRACT

BACKGROUND: There is an increasing desire for contralateral prophylactic mastectomy (CPM) among patients with unilateral breast cancer. It is unknown if risk assessment and genetic testing at the time of diagnosis will aid women in their surgical choice. We report on the uptake and predictors of CPM in women receiving a negative genetic test result for BRCA1 and BRCA2 mutations before surgery. METHODS: Women diagnosed with breast cancer between June 2013 and May 2018 were recruited from four academic health sciences centers in Toronto, Canada. Genetic counseling (risk assessment) and genetic testing was performed prior to surgery. Women were asked about their surgical preference before surgery. At 1 year post-surgery we asked what surgery was completed. This study reports on women who received a negative BRCA1/BRCA2 result. RESULTS: A total of 766 women with a mean age of 46 years (range 21-82) were included in the analysis. Before genetic counseling and testing, 37% of the women were undecided or leaning towards CPM; however, after receiving a negative BRCA test, 15% of the women opted for CPM. Thirty percent of women whose mother died of breast cancer elected for CPM, compared with 15% of women whose mother did not die of breast cancer (p = 0.03). CONCLUSIONS: Women receiving a risk assessment and negative BRCA1/BRCA2 genetic test result before surgery use this information to guide their surgical decision. Uptake of CPM for women who were planning on CPM before genetic testing decreases after receiving a negative BRCA1/BRCA2 genetic test result.

ABSTRACT

BACKGROUND: This study aimed to evaluate the impact of rapid genetic testing (RGT) for BRCA1 and BRCA2 at the time of breast cancer diagnosis on treatment choices. Bilateral mastectomy for the treatment of breast cancer in women with a BRCA1 or BRCA2 mutation offers a reduction in the risk of contralateral breast cancer. It is unclear whether offering RGT at the time of breast cancer diagnosis has an impact on women's surgical decision-making. METHODS: Women with breast cancer diagnosed between June 2013 and May 2018 were recruited from four academic health sciences centers in Toronto, Canada. The participants completed a questionnaire before genetic testing, then one week and one year after disclosure of the genetic test result. Before surgery, RGT was performed. Diagnostic, pathologic, and treatment data were compared between those with and those without a BRCA mutation. RESULTS: The study enrolled 1007 women who consented to RGT. The mean age of the participants was 46.3 years, and the median time to result disclosure was 10 days. A BRCA mutation was found in 6% of the women. The women with a BRCA mutation were significantly more likely to elect for bilateral mastectomy than the women without a BRCA mutation (p < 0.0001). Of the BRCA-positive patients, 95.7% reported that they used their genetic test result to make a surgical decision. CONCLUSIONS: The women provided with RGT at the time of breast cancer diagnosis use the genetic information to make treatment decisions, and the majority of those identified with a BRCA mutation elect for a bilateral mastectomy.

ABSTRACT

BACKGROUND: Full-thickness chest wall resection (FTCWR) is an underused modality for treating locally advanced primary or recurrent breast cancer invading the chest wall, for which little data exist regarding morbidity and mortality. We examined the postoperative complication rates in breast cancer patients undergoing FTCWR using a large multinational surgical outcomes database. METHODS: A retrospective cohort analysis was conducted using the American College of Surgeons National Surgical Quality Improvement Program database. All patients undergoing FTCWR for breast cancer between 2007 and 2016 were identified (n = 137). Primary outcome measures included 30-d postoperative morbidity, composite respiratory complications, and hospital length of stay (LOS). The secondary aim was to compare the postoperative morbidity of FTCWR to those of patients undergoing mastectomy. One-to-one coarsened exact matching was conducted between two groups, which were then compared with respect to morbidity, mortality, reoperations, readmissions, and LOS. RESULTS: The overall rate of postoperative morbidity was 11.7%. Two patients (1.5%) had respiratory complications requiring intubation. Median hospital LOS was 2 d. In the coarsened exact matching analysis, 122 patients were included in each of the two groups. Comparison of matched cohorts demonstrated an overall morbidity for the FTCWR group of 11.5% compared with 8.2% for the mastectomy group (8.2%) (P = 0.52). CONCLUSIONS: FTCWR for the local treatment of breast cancer can be performed with relatively low morbidity and respiratory complications. This is the largest study looking at postoperative complications for FTCWR in the treatment of breast cancer. Future studies are needed to determine the long-term outcomes of FTCWR in this patient population.

ABSTRACT

BACKGROUND: Despite the recent surge in rates of immediate breast reconstruction, there is a paucity of large multicenter studies to compare differences in morbidity after immediate versus delayed breast reconstruction. This study used the National Surgical Quality Improvement Program (NSQIP) to study the association between timing of breast reconstruction and complication rates, stratified by reconstructive modality. STUDY DESIGN: The NSQIP database was used to identify breast reconstructions from 2005 to 2012. Rates of major complications were compared by timing within each reconstructive modality (implant vs autologous). Cohort differences in baseline characteristics and variables associated with increased complication rates were identified in bivariate analyses. A multivariable model was created to compare the association between the timing of reconstruction and major complications. RESULTS: Of 24,506 postmastectomy reconstructions, 85.8% were immediate, 14.2% were delayed, 84% were implant, and 16% were autologous reconstructions. Overall, 10.0% of patients suffered a major complication. After stratification, only implant reconstructions showed a statistically higher complication rate with immediate (8.8%) reconstruction compared with delayed (5.3%) (odds ratio, 1.7, P < 0.01). There was no significant difference in complication rates between autologous immediate (18.4%) or delayed (19.0%) reconstructions. After controlling for baseline cohort differences and other risk factors, immediate reconstruction remained as an independent significant predictor of major complications in implant reconstructions (odds ratio, 1.8, P < 0.01). CONCLUSIONS: Immediate rather than delayed breast reconstruction is associated with a significantly higher rate of major complications in implant reconstruction but not in autologous reconstruction. It is important to include these findings in the routine preoperative surgeon-patient discussion of reconstructive options.

ABSTRACT

BACKGROUND: Whether to undergo postmastectomy breast reconstruction (PMBR) is a challenging, preference-sensitive decision. It is therefore paramount to optimize decision quality through ensuring patients' knowledge and aligning treatments with their personal preferences. This study assessed the effects of a preconsultation educational group intervention (PEGI) on patient knowledge, state-trait anxiety, and decisional conflict (patient uncertainty in decision making) during the decision-making process. METHODS: This phase 3 randomized controlled trial assessed effects of a PEGI in women without active breast cancer undergoing delayed PMBR, or prophylactic mastectomy with immediate PMBR. Both groups underwent routine education before consultation. In addition, the intervention group underwent a PEGI composed of presentations from a plastic surgeon and nurse, a value clarification exercise, and shared experiences from PMBR patients before the consultation with the plastic surgeon. Before and 1-week after consultation, outcome measures were assessed using the Decisional Conflict Scale, State-Trait Anxiety Inventory, and the BREAST-Q. RESULTS: Of the 219 women deemed eligible, a total of 156 women were recruited and randomized. Treatment fidelity was 96% and retention was 88%. At baseline, there were no significant differences in terms of demographic or clinical status, knowledge, state-trait anxiety, and decisional conflict. Patient knowledge about PMBR improved in both groups; however, the degree of knowledge attainment was significantly greater in the PEGI group (24.5% improvement in the intervention group compared with 13.5% in the routine education group, P < 0.001). The reduction in decisional conflict from baseline to follow-up was greater in the intervention group compared with the routine education; however, the difference only approached significance (P = 0.09). CONCLUSIONS: The provision of a preconsultation educational group intervention has been shown to significantly close the knowledge gap on PMBR in patients seeking delayed breast reconstruction or prophylactic mastectomy with immediate breast reconstruction compared with routine education alone.

ABSTRACT

PURPOSE: Although there has been a significant increase in the use of oncoplastic surgery (OPS), data on the postoperative safety of this approach are limited compared to traditional lumpectomy. This study aimed to compare the immediate (30-day) postoperative complications associated with OPS and traditional lumpectomy. METHODS: An analysis of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was performed on women with breast cancer who underwent OPS or traditional lumpectomy. Logistic regression was used to explore the effect of type of surgery on the outcome of interest. RESULTS: A total of 109,487 women were analyzed of whom 8.3% underwent OPS. OPS had a longer median operative time than traditional lumpectomy. The unadjusted immediate (30-day) overall complication rate was significantly higher with OPS than traditional lumpectomy (3.8% versus 2.6%, p < 0.001). After adjusting for baseline differences, overall 30-day postoperative complications were significantly higher amongst women undergoing OPS compared with traditional lumpectomy (OR 1.41, 95%CI 1.24-1.59). Factors that were independent predictors of overall 30-day complications included higher age, higher BMI, race, smoking status, lymph node surgery, neoadjuvant chemotherapy, ASA class ≥ 3, in situ disease, and year of operation. The interaction term between type of surgery and operative time was not statistically significant, indicating that operative time did not modify the effect of type of surgery on immediate postoperative complications. CONCLUSIONS: Although there were slightly higher overall complication rates with OPS, the absolute rates remained quite low for both groups. Therefore, OPS may be performed in women with breast cancer who are suitable candidates.

ABSTRACT

INTRODUCTION: The Ontario High Risk Breast Screening program follows women aged 30-69 at an increased risk of breast cancer, using a yearly mammography and breast MRI. The aim of this study is to determine the clinical outcomes for the enrolled women. METHODS: Observational cohort study following 2081 participants in the high-risk screening program 2011-2017. The participants were divided into three subgroup according to their risk criteria: (a) known carriers of pathogenic variants (PV) in hereditary breast cancer genes. (b) Previous chest radiotherapy. (c) Estimated life time risk (ELR) ≥ 25%, calculated using the International Breast Cancer Intervention Study (IBIS) tool, with no known mutation or previous radiation. All Breast Cancer (BC) diagnosed during the follow-up time were recorded. RESULTS: 673 women carried PVs in hereditary breast cancer genes, 159 had a history of chest radiotherapy, and 1249 had an ELR ≥ 25%. The total cohort of screening years was 8126. Median age at BC diagnosis was 41 for the first group, 47 for the second group and 51 for the third. BC incidence rate was 18.2 for PV mutation carriers, 17.9 for the chest radiotherapy group and 6.2 for ELR ≥ 25%. Hazard ratio was similar for the first two groups, but significantly lower for the ELR ≥ 25% group. When stratifying by age, the incidence rate in the ELR ≥ 25% increased over time, until it became similar to that of the other subgroups after age 50. CONCLUSION: Our findings question the need to screen women with an elevated lifetime risk using the same screening practices used for women who are PV mutation carriers, or with a history of chest radiation, prior to the age of 50.

ABSTRACT

PURPOSE: The goal of this study is to evaluate the frequency and imaging features of lobular neoplasia (LN) diagnosed on MRI-guided biopsy, determine the upgrade rate to malignancy, and assess for any features that may be associated with an upgrade on surgical excision. MATERIALS AND METHODS: Research ethical board approved the review of consecutive patients with MRI-detected LN between January 2009 and December 2018 with differentiation between pure LN and LN with associated other high-risk lesions. The final outcome was determined by final pathology results from surgical excision or 24 months of follow-up. Appropriate statistical tests were used. RESULTS: Out of 1250 MRI-guided biopsies performed, 76 lesions (6%) fulfilled the inclusion criteria and formed the study cohort. Of the 76 lesions, 54 (71%) were pure LN while the rest had coexistent high-risk lesion. Non-mass enhancement (NME) was the most common lesion type (62, 82%). Fifty-nine lesions (78%) were surgically excised, the other 17 had benign follow-up. Overall, 8 lesions (11%) were upgraded to malignancy on final pathology. Malignant outcome was associated with larger lesion size (5.5 versus 1.9 cm, P < 0.001) and a clumped NME pattern (75% versus 24%, P = 0.006). Lesion size and clumped NME remained significantly associated with upgrade on sub-analysis of the pure LN group. CONCLUSION: Larger lesion size and clumped NME are imaging findings associated with upgrade of LN diagnosed by MRI-guided biopsy. This may influence patient management in this clinical setting. Additional larger studies are needed to consolidate our results and to potentially detect additional factors associated with upgrade.

ABSTRACT

BACKGROUND: Women continue to be underrepresented in academic anesthesiology, especially in leadership positions. Possible reasons for this gender disparity include family responsibilities, inadequate mentorship, lack of desire for leadership, the leaky pipeline effect (i.e., attrition of women physicians over the course of their career trajectories), and discrimination. Our objective was to understand the lived experiences of Canadian anesthesiologists in leadership positions. METHODS: In this constructivist grounded theory-inspired study, we used purposeful sampling to identify women anesthesiologists in leadership positions at one Canadian institution. Each participant underwent a one-on-one semi-structured interview of 40-60 min in length, sampling until theoretical saturation was reached. We included questions about the participant's practice setting, influences on their career, and advice the participant would provide to other women in leadership. We used an iterative approach to theoretical sampling and data analysis. The audio-recorded semi-structured interviews were transcribed and coded. NVivo12 was used for open and axial coding, and cross-referencing. RESULTS: Eight women anesthesiologists were recruited and interviewed. Our iterative process identified four interconnected themes: difficulty internalizing a leadership identity, identifying systemic barriers and biases, dissonance between agentic traits and communal social gender roles, and mentorship as shaping lived experiences. Participants consistently expressed experiencing discrimination, articulated barriers related to family responsibilities and ingrained societal expectations, and discussed how typical leadership traits are applied differently to women and men. Women perceived themselves as more compassionate and communicative than men. Despite these traits, these women have expressed barriers to obtaining mentorship. CONCLUSION: We identified consistent interconnected themes among the experiences of our sample of women anesthesiologists in academic leadership and found that academic anesthesiology is a gendered profession as experienced by these women leaders. Further research should focus on strategies to remove barriers to participation in academic anesthesiology for women.


RéSUMé: CONTEXTE: Les femmes continuent d'être sous-représentées en anesthésiologie académique, et tout particulièrement dans les positions de leadership. Parmi les raisons expliquant cette disparité entre les sexes, citons les responsabilités familiales, un mentorat inadapté, le manque de désir de leadership, l'effet de tuyau percé (soit l'attrition des femmes médecins au cours de leur parcours professionnel) et la discrimination. Notre objectif était de comprendre les expériences vécues par les anesthésiologistes canadiennes en position de leadership. MéTHODE: Dans cette étude inspirée de la théorie ancrée constructiviste ('constructivist grounded theory'), nous avons utilisé un échantillonnage ciblé afin d'identifier les femmes anesthésiologistes en position de leadership dans un établissement canadien. Chaque participante a pris part à un entretien semi-structuré privé de 40-60 minutes, soit jusqu'à atteindre une saturation théorique. Nous avons inclus des questions concernant le cadre de pratique des participantes, les influences sur leur carrière, et les conseils qu'elles donneraient à d'autres femmes en position de leadership. Nous avons utilisé une approche itérative pour l'échantillonnage théorique et l'analyse de données. Un enregistrement sonore des entretiens semi-structurés a été réalisé pour être ensuite retranscrit et codé. Le progiciel NVivo12 a été utilisé pour le codage ouvert et axial ainsi que pour le référencement croisé. RéSULTATS: Huit femmes anesthésiologistes ont été recrutées et interviewées. Notre processus itératif nous a permis d'identifier quatre thèmes interconnectés : la difficulté d'internaliser une identité de leader, l'identification d'obstacles et de biais systémiques, la dissonance entre l'agentivité individuelle et les rôles de genre socialement construits, et le mentorat en tant que formatif des expériences vécues. Les participantes ont toutes exprimé ressentir de la discrimination, elles ont articulé des obstacles liés aux responsabilités familiales et aux attentes sociétales enracinées, et ont expliqué comment les caractéristiques typiques de leadership étaient appliquées différemment selon le sexe. Les femmes se percevaient comme étant plus empathiques et communicatives que les hommes. Malgré ces traits de caractère, ces femmes ont exprimé qu'il existait des obstacles à l'obtention de mentorat. CONCLUSION: Nous avons identifié plusieurs thèmes interconnectés récurrents parmi les expériences de notre échantillonnage de femmes anesthésiologistes dans des positions de leadership académique et observé que l'anesthésiologie en milieu académique est une profession genrée, comme l'ont ressenti ces femmes leaders. Les recherches futures devraient mettre l'accent sur des stratégies visant à déjouer les obstacles à la participation des femmes en anesthésiologie académique.

ABSTRACT

Summary: Surgeons are frequently perceived by medical students to be uncompassionate, resolute and individualistic. Surgical education often prioritizes teaching and learning approaches that perpetuate these perceptions. In other specialties, engaging patients in education has shown promise in refocusing attention from the technical and procedural aspects of care toward the humanistic and social aspects. Despite proven favourable outcomes for both patients and students in many clinical areas, a "patient as teacher" approach to surgical education has yet to be adopted widely in Canada. A patient as teacher program was developed for surgical clerks at the University of Toronto with the goal of emphasizing the humanity of the patient, the psychosocial impact of a surgical diagnosis of breast cancer on patients and their families, and the social and humanistic roles for surgeons in providing patient-centred care. We report on the program's development process and pilot session.

ABSTRACT

BACKGROUND: The rates of contralateral prophylactic mastectomy (CPM) are increasing in women with breast cancer. Previous retrospective research has examined clinical and demographic predictors of the uptake of CPM. However, to the authors' knowledge, there has been very little prospective research to date that has examined psychosocial functioning prior to breast cancer surgery to determine whether psychosocial functioning predicts uptake of CPM. The current study was conducted to evaluate demographic, clinical, and psychosocial predictors of the uptake of CPM in women with unilateral breast cancer without a BRCA1 or BRCA2 mutation. METHODS: Women with unilateral non-BRCA-associated breast cancer completed questionnaires prior to undergoing breast cancer surgery. Participants completed demographic and psychosocial questionnaires assessing anxiety, depression, cancer-related distress, optimism/pessimism, breast satisfaction, and quality of life. Pathological and surgical data were collected from medical charts. RESULTS: A total of 506 women consented to participate, 112 of whom (22.1%) elected to undergo CPM. Age was found to be a significant predictor of CPM, with younger women found to be significantly more likely to undergo CPM compared with older women (P < .0001). The rate of CPM was significantly higher in women with noninvasive breast cancer compared with those with invasive breast cancer (P < .0001). Women who elected to undergo CPM had lower levels of presurgical breast satisfaction (P = .01) and optimism (P = .05) compared with women who did not undergo CPM. CONCLUSIONS: Psychosocial functioning at the time of breast cancer surgery decision making impacts decisions related to CPM. Women who have lower levels of breast satisfaction (body image) and optimism are more likely to elect to undergo CPM. It is important for health care providers to take psychosocial functioning into consideration when discussing surgical options.

ABSTRACT

PURPOSE: The safety of immediate breast reconstruction (IBR) in older women is largely unknown. This study aimed to determine the 30-day postoperative complication rates following IBR (implant-based or autologous) in older women (≥ 70 years) with breast cancer and to compare them to younger women (18-69 years). METHODS: The National Surgical Quality Improvement Program (NSQIP) database was used to identify women with in situ or invasive breast cancer who underwent IBR (2005-2016). Outcomes included 30-day postoperative morbidity and mortality, which were compared across age groups stratified by type of reconstruction. RESULTS: Of 28,850 women who underwent implant-based and 9123 who underwent autologous reconstruction, older women comprised 6.5% and 5.7% of the sample, respectively. Compared to younger women, older women had more comorbidities, shorter operative times, and longer length of hospital stay. In the implant-based reconstruction group, the 30-day morbidity rate was significantly higher in older women (7.5% vs 5.3%, p < 0.0001) due to higher rates of infectious, pulmonary, and venous thromboembolic events. Wound morbidity and prosthesis failure occurred equally among age groups. In the autologous reconstruction group, there was no statistically significant difference in the 30-day morbidity rates (older 9.5% vs younger 11.6%, p = 0.15). Both wound morbidity and flap failure rates were similar between the two age groups. For both reconstruction techniques, mortality within 30 days of breast surgery was rare. CONCLUSION: Immediate breast reconstruction is safe in older women. These data support the notion that surgeons should discuss IBR as a safe and integral part of cancer treatment in well-selected older women.
