The Effect of Lumpectomy and Cavity Shave Margin Status on Recurrence and Survival in Breast-Conserving Surgery.

BACKGROUND/OBJECTIVE: Cavity shave margins (CSMs) decrease rate of positive margins and need for re-excision. Recurrence data following breast-conserving surgery (BCS) are not always available in large cancer registries. We sought to define our recurrence and survival data in BCS with routine excision of CSMs. METHODS: A single institution, 10-year retrospective review of breast cancer patients who underwent BCS with routine CSMs was conducted. Cavity shave margin technique was standard. Cox proportional hazard analyses and the Kaplan-Meier method were used to estimate recurrence and survival. RESULTS: Breast-conserving surgery with CSM was performed in 839 patients. Re-excision rate to achieve negative margins was 8.5%. Fifty-two patients (75%) underwent margin re-excision vs 18 patients (25%) underwent salvage mastectomy. Positive margin rate stratified by tumor histology was highest for invasive lobular carcinoma followed by mixed invasive ductal carcinoma (IDC) and ductal carcinoma in situ (DCIS), followed by pure DCIS and lowest for IDC. Length of follow-up was (4.7 ± 2.6, years). Overall recurrence rate (locoregional and systemic) was 4.3%: highest in patients with negative lumpectomy margin but positive CSM (L-S+ = 15%) followed by positive lumpectomy and CSMs (L+S+ = 14%), followed by patients with positive lumpectomy margin but negative CSMs (L+S- = 13%) and lowest for negative lumpectomy and CSM (L-S- = 5%), (P = .0008). There was no difference in 5-year breast cancer-specific survival between the 4 subgroups: 96% for L-S-, 86.7% L-S+, 94.7% L+S+ and 90% L+S- (P = .094). CONCLUSIONS: Recurrence following BCS with CSMs can be stratified based on both lumpectomy and cavity shave margin positivity. Routine excision of CSMs allows identification of these patient subsets.

Intraoperative Radiation Therapy Versus Whole Breast Radiation for Early-Stage Breast Cancer Treatment in Rural Appalachia.

BACKGROUND: Intraoperative radiation therapy (IORT) is an alternate accelerated form of radiation following breast-conserving surgery (BCS). Lack of data regarding long-term outcomes has limited adoption. We report our experience with IORT in patients undergoing BCS versus whole breast radiation therapy (WBRT). METHODS: Retrospective review of patients undergoing BCS with IORT versus WBRT (2012-2017). Inclusion: low grade, T1-2N0M0, estrogen receptor/progesterone receptor positive, and Her2-negative infiltrating ductal carcinomas. IORT was delivered as a single fraction of radiation (20 Gy) intraoperatively. Outcomes were compared using Fisher's test for discrete variables or Wilcoxon signed-rank test for continuous variables. Kaplan-Meier method was used to estimate disease-free survival (DFS). RESULTS: Fifty-one patients (44%) received IORT, and 66 (56%) received WBRT. There was no difference in age, tumor size, receptor status, or in-breast recurrence (1.9% vs 0%, all P > .05). Length of follow-up was longer in the WBRT group due to time to inception of IORT (mean ± SD: 44 ± 8.1 vs 73 ± 13 months, P < .001). There was no difference in DFS between the 2 groups (HR 2.5; P = .44). IORT patients experienced delay to BCS (mean ± SD: 38 ± 12.7 vs 27 ± 12.2 days, P < .001) likely due to coordination of care. Analysis demonstrated IORT patients would have traveled a mean distance of 20 miles to the closest WBRT center (range 1-70, miles) for a mean travel time of 31 minutes (range 4-90, minutes) per WBRT treatment. DISCUSSION: IORT produces noninferior oncologic outcomes and decreased skin toxicity compared with WBRT. It can be convenient for patients in rural regions with limited health care access.

Paget-Schroetter syndrome in pregnancy: A case report and discussion of management options.

Paget-Schroetter syndrome is a form of primary venous thoracic outlet syndrome whereby thrombosis of the subclavian vein is instigated by repeated and vigorous overhead activity of the arm. We describe a 35-year-old pregnant white woman at 8 weeks' gestation, a competitive swimmer by profession, who was diagnosed with a left upper extremity thrombus. First rib resection through an infraclavicular approach was performed 1 week after percutaneous pharmacomechanical thrombectomy. Repeated venography demonstrated residual thrombus requiring percutaneous pharmacomechanical thrombectomy with balloon venoplasty. We present a challenging case with focus on the unique diagnostic evaluation and management of pregnant patients with this condition.

Enhancing the Educational Value and Faculty Attendance of a Morbidity and Mortality Conference.

OBJECTIVE: There exists significant variation in the approach to and execution of morbidity and mortality conference (M&MC). Faculty attendance remains a working challenge. We sought to change our department's M&MC and hypothesized improved educational value and attendance. DESIGN: Complications were submitted in Clavien-Dindo format. A designated M&MC moderator facilitated discussion. A teaching point (TP) was assigned to each complication intended to be the focus of discussion. Presentations followed a structured 6-slide PowerPoint template. A web-based tool using Google Forms was developed and distributed as an "App" for tracking of attendance. An anonymous online survey was distributed to participants to elucidate perception of M&MC following the intervention. SETTING: Academic medical center. PARTICIPANTS: Postgraduate year-1 to 5 surgery residents and faculty at West Virginia University, Morgantown. RESULTS: Forty-eight of sixty-three surveys were returned (response rate 76%). Twenty-five faculty (70%) and 23 residents (82%) responded. A predetermined TP was viewed as the most favorable change made by both faculty and residents. 65% of faculty and residents acknowledged improved educational value, 58% found a single moderator to help streamline Morbidity and Mortality (M&M) presentations and 71% felt that a standard PowerPoint template improved quality of presentations. Both residents (96%) and faculty (68%) believed a predetermined TP improved the educational value of the conference and medical knowledge during preparation. More residents (43%) than faculty (16%) believed that changes to the department's M&MC format allowed better identification of quality improvement issues. Furthermore, the majority of residents (83%) believed that changes to the department's M&M format allowed better identification of system factors compared to faculty (32%), p = 0.003. Faculty participation increased from 60% to 80% after changes (p = 0.03). CONCLUSIONS: The educational value of M&MC and attendance can be improved with simple changes, but faculty and residents may have different expectations and perceptions.

Laparoscopic Removal of Angelchik Prosthesis Followed by Interval Sleeve Gastrectomy.

INTRODUCTION: The Angelchik prosthesis (AP) is a historic antireflux device which consists of a C-shaped silicone ring placed around the gastroesophageal junction (GEJ) and secured by Dacron tape. We present a rare experience with an AP and its impact on bariatric surgical outcomes. CASE: Our patient is a 66-year-old woman who had an open antireflux procedure with an AP in 1987. She presented to a bariatric clinic for consideration of bariatric surgery for the treatment of morbid obesity and associated comorbidities. She also reported significant problems with reflux and dysphagia. After an appropriate work-up, an AP was identified at her GEJ. She was taken to the operating room for laparoscopic removal with planned interval laparoscopic sleeve gastrectomy. Intraoperatively, the AP was identified around the GEJ; after extensive adhesiolysis, the prosthesis was removed. Postoperatively, in order to determine if the AP had caused any lasting esophageal motility problems, the patient underwent a high-resolution esophageal manometry which demonstrated normal esophageal motility. Interval laparoscopic sleeve gastrectomy was performed safely 9 weeks later. CONCLUSION: Although rarely used, it is still possible to encounter an Angelchik prosthesis in practice. General and bariatric surgeons need to be aware of this rare device and understand how to manage its related complications.

What operation for recurrent rectal prolapse after previous Delorme's procedure? A practical reality.

AIM: To report our experience with perineal repair (Delorme's procedure) of rectal prolapse with particular focus on treatment of the recurrence. METHODS: Clinical records of 40 patients who underwent Delorme's procedure between 2003 and 2014 were reviewed to obtain the following data: Gender; duration of symptoms, length of prolapse, operation time, ASA grade, length of post-operative stay, procedure-related complications, development and treatment of recurrent prolapse. Analysis of post-operative complications, rate and time of recurrence and factors influencing the choice of the procedure for recurrent disease was conducted. Continuous variables were expressed as the median with interquartile range (IQR). Statistical analysis was carried out using the Fisher exact test. RESULTS: Median age at the time of surgery was 76 years (IQR: 71-81.5) and there were 38 females and 2 males. The median duration of symptoms was 6 mo (IQR: 3.5-12) and majority of patients presented electively whereas four patients presented in the emergency department with irreducible rectal prolapse. The median length of prolapse was 5 cm (IQR: 5-7), median operative time was 100 min (IQR: 85-120) and median post-operative stay was 4 d (IQR: 3-6). Approximately 16% of the patients suffered minor complications such as - urinary retention, delayed defaecation and infected haematoma. One patient died constituting post-operative mortality of 2.5%. Median follow-up was 6.5 mo (IQR: 2.15-16). Overall recurrence rate was 28% (n = 12). Recurrence rate for patients undergoing an urgent Delorme's procedure who presented as an emergency was higher (75.0%) compared to those treated electively (20.5%), P value 0.034. Median time interval from surgery to the development of recurrence was 16 mo (IQR: 5-30). There were three patients who developed an early recurrence, within two weeks of the initial procedure. The management of the recurrent prolapse was as follows: No further intervention (n = 1), repeat Delorme's procedure (n = 3), Altemeier's procedure (n = 5) and rectopexy with faecal diversion (n = 3). One patient was lost during follow up. CONCLUSION: Delorme's procedure is a suitable treatment for rectal prolapse due to low morbidity and mortality and acceptable rate of recurrence. The management of the recurrent rectal prolapse is often restricted to the pelvic approach by the same patient-related factors that influenced the choice of the initial operation, i.e., Delorme's procedure. Early recurrence developing within days or weeks often represents a technical failure and may require abdominal rectopexy with faecal diversion.
