Practicing Surgeons' Perception of Barriers to Palliative Care Delivery in British Columbia.

BACKGROUND: Utilization of palliative care remains low among surgical patients. We aim to characterize general surgeons' perceptions of barriers to access palliative care in British Columbia (BC). METHODS: Semi-structured interviews were carried out with a total of 11 surgeons in BC. Interviews were transcribed for thematic analysis via interpretive description. Dominant themes were identified and agreed upon between the authors. RESULTS: Several barriers were identified, which include system and institution, communication and surgical workflow barriers. At the system and institutional level, there were difficulties accessing patient information and continuity of care. Themes in the communication included patient misconceptions about palliative care and communication challenges with consulting services. Surgical workflow barriers influenced the overall perceived role of surgeons when caring for patients with palliative care needs. CONCLUSION: Understanding surgeons' perspectives on barriers to palliative care is an important step in changing management. This can aid in the development of strategies that ease access to palliative care.

Knowledge, perceptions, attitudes, and barriers pertaining to genetic literacy among surgeons: a scoping review.

BACKGROUND: The rapid evolution of genetic technologies and utilization of genetic information for clinical decision-making has necessitated increased surgeon participation in genetic counselling, testing, and appropriate referral of patients for genetic services, without formal training in genetics. We performed a scoping review to describe surgeons' knowledge, perceptions, attitudes, and barriers pertaining to genetic literacy in the management of patients who had confirmed cancer or who were potentially genetically at risk. METHODS: We conducted a scoping review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews checklist. We performed a comprehensive literature search, and 2 reviewers independently screened studies for inclusion. These studies included surgeons involved in the care of patients with confirmed gastrointestinal, breast, and endocrine and neuroendocrine cancers, or patients who were potentially genetically at risk for these cancers. RESULTS: We analyzed 17 studies, all of which used survey or interview-based formats. Many surgeons engaged in genetic counselling, testing, and referral, but reported low confidence and comfort in doing so. Knowledge assessments showed lower confidence in identifying genetic inheritance patterns and hereditary cancer syndromes, but awareness was higher among surgeons with greater clinical volume or subspecialty training in oncology. Surgeons felt responsible for facilitating these services and explicitly requested educational support in genetics. Barriers to genetic literacy were identified and catalogued at patient, surgeon, and system levels. CONCLUSION: Surgeons frequently engage in genetics-related tasks despite a lack of formal genetics training, and often report low knowledge, comfort, and confidence in providing such services. We have identified several barriers to genetic literacy that can be used to develop interventions to enhance genetic literacy among surgeons.

Bone health after RRBSO among BRCA1/2 mutation carriers: a population-based study.

OBJECTIVE: Examine the risks of fractures and osteoporosis after risk-reducing bilateral salpingo-oophorectomy (RRBSO) among women with BRCA1/2 mutations. METHODS: In this retrospective population-based study in British Columbia, Canada, between 1996 to 2017, we compared risks of osteoporosis and fractures among women with BRCA1/2 mutations who underwent RRBSO before the age of 50 (n=329) with two age-matched groups without known mutations: 1) women who underwent bilateral oophorectomy (BO) (n=3,290); 2) women with intact ovaries who had hysterectomy or salpingectomy (n=3,290). Secondary outcomes were: having dual-energy X-ray absorptiometry (DEXA) scan, and bisphosphonates use. RESULTS: The mean age at RRBSO was 42.4 years (range, 26-49) and the median follow-up for women with BRCA1/2 mutations was 6.9 years (range, 1.1-19.9). There was no increased hazard of fractures for women with BRCA1/2 mutations (adjusted hazard ratio [aHR]=0.80; 95% confidence interval [CI]=0.56-1.14 compared to women who had BO; aHR=1.02; 95% CI=0.65-1.61 compared to women with intact ovaries). Among women who had DEXA-scan, those with BRCA1/2 mutations had higher risk of osteoporosis (aHR=1.60; 95% CI=1.00-2.54 compared to women who had BO; aHR=2.49; 95% CI=1.44-4.28 compared to women with intact ovaries). Women with BRCA1/2 mutations were more likely to get DEXA-scan than either control groups, but only 46% of them were screened. Of the women with BRCA1/2 mutations diagnosed with osteoporosis, 36% received bisphosphonates. CONCLUSION: Women with BRCA1/2 mutations had higher risk of osteoporosis after RRBSO, but were not at increased risk of fractures during our follow-up. Low rates of DEXA-scan and bisphosphonates use indicate we can improve prevention of bone loss.

Risk of cardiovascular disease among women carrying BRCA mutations after risk-reducing bilateral salpingo-oophorectomy: A population-based study.

OBJECTIVE: Examine the risk of cardiovascular disease (CVD) following risk reducing bilateral salpingo-oophorectomy (RRBSO) among women with BRCA mutations. METHODS: In this retrospective population-based study in British Columbia, Canada, between 1996 and 2017, we compared the risk of CVD among women with known BRCA mutations who underwent RRBSO before the age of 50 (n = 360) with two groups of age-matched women without known BRCA mutations: 1) women who underwent bilateral oophorectomy (BO) for benign conditions (n = 3600); and, 2) women with intact ovaries who had hysterectomy or salpingectomy (n = 3600). Our primary outcome was CVD (a composite (any of) myocardial infarction, heart failure, and/or cerebrovascular disease). Secondary outcomes included a diagnostic code for predisposing conditions (hypertension, dyslipidemia, and/or diabetes mellitus), and use of cardioprotective medications (statins and/or beta-blockers). RESULTS: We report no significant increased risk for CVD between women with BRCA mutations and women who underwent BO (aHR = 1.08, 95%CI: 0.72-1.62), but women with BRCA mutations were less likely to be diagnosed with predisposing conditions (aHR = 0.69, 95%CI: 0.55-0.85). Compared to women without BRCA mutations with intact ovaries who underwent hysterectomy or salpingectomy, women with BRCA mutations had significantly increased risk for CVD (aHR = 1.82, 95%CI: 1.18-2.79) and were less likely to be diagnosed with predisposing conditions (aHR = 0.78, 95%CI: 0.62-0.97) and to fill cardioprotective medications (aHR = 0.88, 95%CI: 0.64-1.22). CONCLUSION: Our results suggest an opportunity for improved prevention of CVD in women with BRCA mutations after prophylactic oophorectomy. Despite the observed lower prevalence of predisposing conditions for CVD and lesser use of cardioprotective medications, this population did not have a lower rate of CVD.

Sentinel Node Biopsy Should Not be Routine in Older Patients with ER-Positive HER2-Negative Breast Cancer Who Are Willing and Able to Take Hormone Therapy.

BACKGROUND: The SSO Choosing Wisely campaign recommended selective sentinel lymph node biopsy (SLNB) in clinically node-negative women aged ≥ 70 years with ER+ breast cancer. We sought to assess the association of SLNB positivity, adjuvant treatment, and survival in a population-based cohort. PATIENTS AND METHODS: Women aged ≥ 70 years treated for ER+ HER2- breast cancer between 2010 and 2016 were identified in our prospective provincial database. Overall survival (OS) and breast cancer-specific survival (BCSS) were assessed using Kaplan-Meier analysis. Multivariable logistic regression was used to assess the association of SLNB positivity with use of adjuvant treatments and survival outcomes. RESULTS: We identified 2662 patients who met study criteria. SLNB was positive in 25%. Increased use of chemotherapy (ChT), hormone therapy (HT), and radiotherapy (RT) was significantly associated with SLNB positivity. Five-year OS was 86%, and BCSS was 96% with median follow-up of 4.3 years. BCSS was worse with grade 3 disease (HR 4.1, 95% CI 2.1-8.1, p < 0.0001) and better with HT (HR 0.5 95% CI 0.3-0.9, p = 0.01). Patients with a positive SLNB treated without adjuvant therapy had lower BCSS (HR 3.2 95% CI 1.2-8.4, p = 0.017) than those with a negative SLNB, but patients with a positive SLNB treated with any combination of ChT, HT, and/or RT, had similar BCSS to those with a negative SLNB. CONCLUSIONS: BCSS in this population was excellent at 96%, and BCSS was similar with negative and positive SLNB when patients received HT. SLNB can be omitted in elderly patients willing to take HT.

Prophylactic Surgery in the BRCA+ Patient: Do Women Develop Breast Cancer While Waiting?

Breast cancer susceptibility gene (BRCA) mutation carriers have an increased risk of breast cancer. Mitigation of this risk can be achieved via surveillance or prophylactic mastectomy with or without breast reconstruction. Those that choose surgery expect to reduce their chance of developing cancer. The purpose of this study was to determine the incidence of patients developing breast cancer prior to surgery and to identify modifiable contributing factors within the patient journey. This is a historical cohort study of all BRCA mutation carriers identified through the British Columbia Cancer Hereditary Cancer Program between 2000 and 2012. Patients were divided into two groups: surveillance (S) and prophylactic mastectomy with immediate breast reconstruction (PM/IBR). The incidence of cancer, time to PM/IBR and patient journeys were analyzed. A total of 333 women were identified. The time to surgery from mutation disclosure was a median of 31 (5.3, 75.7) months. During this period, 6% of patients developed breast cancer compared with a 14% incidence of breast cancer in patients choosing surveillance. The majority of time to surgery was attributed to the period between mutation disclosure and the decision to proceed with surgery. Strategies to facilitate decision-making as well as wait list prioritization and dedicated operative time should be targeted to this population to decrease the number of women developing an interval cancer prior to surgery.

Do surgeons convey all the details? A provincial assessment of operative reporting for breast cancer.

INTRODUCTION: A breast cancer synoptic operative report was developed using a modified Delphi process METHODS: Data from the British Columbia Cancer Breast Cancer Outcomes Unit (BCOU) was used to analyze the association between the completion of a synoptic operative report and reporting of operative details and The American Society of Breast Surgeons quality indicators. RESULTS: 3662 patients had surgery for breast cancer by 185 surgeons. 2281 reports were narrative and 1007 synoptic. Requested surgical details were more commonly reported with synoptic reports for both posterior (96 vs 58%, p < 0.0001) and anterior margins (96 vs 5%, p < 0.0001). This was true for high and low volume surgeons. Quality Indicators were higher in those cases with an associated synoptic report for high and low volume surgeons. CONCLUSION: Communication of operative details is improved with synoptic reporting. Investment in platforms to facilitate synoptic reporting could improve patient care through improved multidisciplinary communication.

Practice referral patterns and outcomes in patients with primary retroperitoneal sarcoma in British Columbia.

BACKGROUND: We examined practice referral patterns for primary retroperitoneal sarcoma (PRS) in British Columbia (BC) and associations between the timing of referral to tertiary care and patient outcomes. METHODS: Using ICD-10 coding, the Cancer Agency Information System was used to identify patients with PRS from 2000 to 2009 who had been referred to tertiary care and had undergone a surgical resection. RESULTS: Eighty-two patients were included. Those referred before surgery were significantly more likely to receive a complete resection (P = .0002) and adjuvant radiation (P = .0000) compared with patients referred after surgery. Referral before surgery was associated with a significantly increased overall (P = .0619) and recurrence-free (P = .0400) survival; however, in the multivariate model this was not significant. CONCLUSIONS: Referral before surgery is associated with higher rates of complete resection and the use of adjuvant radiation; furthermore, it is associated with prolonged survival in the univariate but not in the multivariate model.

Effect of systematic education courses on rectal cancer treatments in a population.

PURPOSE: In a strategy aimed to improve perioperative and operative management of rectal cancer in British Columbia (BC), a series of educational events were provided for BC surgeons, radiation oncologists, and pathologists including teaching on the use of preoperative radiation, surgical technique with total mesorectal excision (TME), and pathology reporting. Seminars were offered during 2002 and 2003 each over 2 days with documented attendance from 30 hospitals in the province. We wished to determine whether frequency of preoperative radiation and TME surgery changed on a population level after the rectal cancer education courses in 2002 and 2003. METHODS: All patients were referred to the BC Cancer Agency, the only center for radiation in BC. Treatments and data were abstracted from the Colorectal Cancer Outcomes Unit database. Patients with resected stage I to III rectal cancer were included who were diagnosed before (2000-2001) and after (2004) the education courses. We used changes from 2000 to 2001 to reflect effects of sporadic continued medical education (CME) compared with effects of formal systematic provincial education courses (changes from 2001 to 2004). RESULTS: A total of 778 eligible patients were included from 2000 (n = 264), 2001 (n = 202), and 2004 (n = 312). The percentage of stage III patients was similar in the 3 time periods. The use of preoperative radiation therapy increased significantly over time, 43% (114/264), 56% (113/202), and 86% (268/312) (P < .0001). TME use also increased significantly, 35%, 44%, and 71% (P < .0001). CONCLUSIONS: The implementation of guidelines for the use of preoperative radiation and TME by formal systematic provincial education courses for surgeons, radiation oncologists, and pathologists resulted in significant improvements in rectal cancer management on a provincial level. Such programs may be more effective than "sporadic" CME, particularly in multidisciplinary and complex care settings like adjuvant rectal cancer therapy.

Effects of change in rectal cancer management on outcomes in British Columbia.

BACKGROUND: In a province-wide audit of patients undergoing treatment for rectal cancer in British Columbia in 1996, the 4-year rate of pelvic recurrence for stage 3 rectal cancer was 27%. The management guidelines were changed in 2002 to include adjuvant short-course preoperative radiation and total mesorectal excision surgical techniques. Education workshops were held to implement the protocol change. METHODS: We performed a provincial audit of rectal cancer cases for patients treated in the year after the protocol change, and we compared the pelvic recurrence rates with those from the audit performed in 1996. RESULTS: During a 12-month period beginning Oct. 1, 2003, a total of 367 patients underwent radical resection of rectal cancer with a curative intent. Preoperative adjuvant radiotherapy was used in 54% of cases (197/367). Median follow-up was 34.5 months, and 91% of patients were followed for at least 2 years. Relative to the 1996 cohort, there was a decreasing trend in 2-year overall pelvic recurrence rates in the 2003/04 cohort (9.6% v. 6.9%) and a significant decrease in recurrence among patients with stage 3 cancers (18.2% v. 9.2%; p = 0.020). Use of adjuvant radiation increased significantly (37% v. 65%; p < 0.001), and negative radial margins were achieved in 87% (319/367) of cases. CONCLUSION: The rates of pelvic recurrence were improved after changes in the management guidelines advocating increased use of total mesorectal excision surgery and preoperative radiation. Knowledge translation with an integrated strategy among surgeons and medical and radiation oncologists was successful in improving population outcomes among patients with rectal cancer.

Self-assessment during a 2-day laparoscopic colectomy course: can surgeons judge how well they are learning new skills?

BACKGROUND: The objectives of this study were to (1) establish the utility of an assessment tool for participants in a laparoscopic colectomy course and (2) to determine the accuracy of technical skill self-assessment in this group. METHODS: Twenty-two surgeons enrolled in a 2-day course participated. During the animal laboratory, each participant's operative performance was videotaped. Participants completed a global rating scale (GRS) instrument to self-assess their performances. By using the same GRS, 2 trained raters independently assessed each performance by videotape review. RESULTS: For the trained raters, the GRS showed excellent interrater reliability (r = .76, P < .001). There was no correlation between trained rater scores and self-assessment scores. Furthermore, the trained rater scores (mean, 2.62 and 2.99) were significantly lower than the self-assessment scores (4.05, P < .001). CONCLUSIONS: Surgeons consistently overestimated their performance during a laparoscopic colectomy course as measured by reliable GRS. This finding highlights the issue of credentialing and the importance of preceptorship for surgeons completing such courses.

Evaluating learning and knowledge retention after a continuing medical education course on total mesorectal excision for surgeons.

The purpose of this study was to determine whether knowledge gained (as determined by a formal course test) by surgeons in a continuing education course on total mesorectal excision and rectal cancer management is retained 1 year later. A formal course test had been previously developed and validated. The test evaluated course content including pelvic anatomy, surgical techniques, imaging, pathology, adjuvant therapies, and cancer and functional outcomes. Validation was determined by the absence of change in pre- and posttest scores of the "expert" course instructors (n = 8, P = .6) and by a linear correlation in test scores with increasing level of general-surgery resident training (n = 16, P = .001). Significant learning by the 58 surgeons taking the course had been shown by improvement in test scores from before the course (mean score 19) to after the course (mean score 25.3, P = .001, out of a possible 33 total mark). At 1 year after the course, those course participants (n = 44, 76%) who had provided postcourse contact information were asked to complete the course test again. Responses were received from 18 surgeons (41% of those surveyed, 31% of the original course participants). The mean score on the test after 1 year was 23.8. Compared with the immediate posttest scores, there was no significant knowledge loss over the year (P = .09). We conclude that knowledge acquired during a continuing education course for surgeons on total mesorectal excision and rectal-cancer management is retained 1 year later.

Can cytology accurately predict benign follicular nodules?

BACKGROUND: The reliability of fine-needle aspiration (FNA) biopsy in differentiating benign from malignant follicular lesions of the thyroid has been the subject of renewed debate recently. Although surgical excision has been recommended for most follicular lesions identified by cytology, this approach may not be necessary in all cases. The goal of this study was to determine whether FNA could be used as a diagnostic tool to safely identify patients with follicular thyroid nodules who do not require immediate surgical intervention. METHODS: A retrospective review was performed on a sample of 24 patients diagnosed with either follicular adenoma or follicular carcinoma after surgical excision of a thyroid nodule. The initial FNA biopsies were independently reviewed by two experienced cytopathologists in a blinded fashion and subsequently compared with final histologic diagnoses. RESULTS: For pathologist A, overall accuracy was 58%. The positive predictive value (PPV) of a benign diagnosis was 82%; PPV of a malignant diagnosis was 38%. For pathologist B, overall accuracy was 63%. The PPV of a benign diagnosis was 83%; PPV of a malignant diagnosis was 42%. CONCLUSIONS: This study suggests that in follicular lesions of the thyroid, a benign FNA biopsy report from an experienced cytopathologist has a high positive predictive value. The predictive value may not, however, be high enough to preclude surgery; other factors may need to be considered before recommending a nonoperative approach.

Effect of emergent presentation on outcome from rectal cancer management.

BACKGROUND: We have previously reported outcomes for all rectal cancers in BC in 1996. We found that our local recurrence rates and survival were suboptimal relative to current standards in recent literature. METHODS: In this retrospective, population-based study, we report the influence of emergent presentation (obstruction, perforation, massive hemorrhage) on outcomes, types of surgical procedures and use of staging investigations, and use of adjuvant radiation and chemotherapy. RESULTS: There were 452 invasive adenocarcinomas of the rectum of which 45 were emergent and 407 nonemergent. Disease-specific survival at 4 years for emergent and nonemergent stage II cancers were 66% versus 80%, respectively, and for stage III cancers, 60% versus 73%, respectively (P <0.04). Local recurrence rates at 4 years for emergent and nonemergent stage II cancers were 20% versus 15%, respectively, and for stage III cancers, 70% and 20%, respectively (P <0.05). Surgical resection more frequently involved a stoma for emergent (60%) than for nonemergent (35%) cases (P <0.01). Percent of patients having complete staging investigations were similar between emergent (42%) and nonemergent patients (39%). Adjuvant radiation was given in similar proportion to emergent (61%) and nonemergent (55%) patients. Adjuvant chemotherapy was given to a slightly higher proportion of emergent patients (63%) than nonemergent patients (43%). CONCLUSIONS: We conclude that outcome from rectal cancer management is worse for emergent than nonemergent presentation. Since there is no difference in use of staging investigations or adjuvant therapy, the difference in outcome is likely due to difference in surgical technique between emergent and nonemergent cases.

Effects of positive resection margin and tumor distance from anus on rectal cancer treatment outcomes.

PURPOSE: Rectal cancer outcome depends on stage, technical aspects of surgical excision, and use of adjuvant chemoradiation. Here, we examine effects of positive resection margin and tumor distance from the anus in stage 2 and 3 cancers on 4-year disease-specific survival and recurrence. METHODS: We reviewed all 495 rectal cancer patients registered in British Columbia in 1996. RESULTS: There were 481 cases analyzed: 29 in situ, 134 stage 1, 107 stage 2, 100 stage 3, 83 stage 4, and 28 unknown stage. Survival was significantly affected by presence of positive resection margin in stage 2 and 3 cancers, P = 0.0001. Lower tumor distance from the anus for stage 2 and 3 cancers worsened survival, P = 0.0007, and overall recurrence, P =0.016, but not local recurrence, P = 0.11. Adjuvant postoperative combined radiation and chemotherapy in stage 2 and 3 cancers significantly improved survival, P = 0.070 and local recurrence, P = 0.018, but not overall recurrence, P = 0.19. CONCLUSIONS: Presence of positive resection margin and tumor distance from the anus affect survival, local recurrence, and overall recurrence. Adjuvant postoperative combined radiation and chemotherapy improved our outcomes. Our local recurrence rates for rectal cancers are worse than currently reported standards of less than 10%. Improved surgical excision and use of adjuvant preoperative radiation and chemotherapy may improve outcome.
