ABSTRACT

INTRODUCTION: Fragmentation of care (FC, the receipt of care at > 1 institution) has been shown to negatively impact cancer outcomes. Given the multimodal nature of breast cancer treatment, we sought to identify factors associated with FC and its effects on survival of breast cancer patients. METHODS: A retrospective analysis was performed of surgically treated, stage I-III breast cancer patients in the 2004-2020 National Cancer Database, excluding neoadjuvant therapy recipients. Patients were stratified into two groups: FC or non-FC care. Treatment delay was defined as definitive surgery > 60 days after diagnosis. Multivariable logistic regression was performed to identify factors predictive of FC, and survival was compared using Kaplan-Meier and multivariable Cox proportional hazards methods. RESULTS: Of the 531,644 patients identified, 340,297 (64.0%) received FC. After adjustment, FC (OR 1.27, 95% CI 1.25-1.29) was independently associated with treatment delay. Factors predictive of FC included Hispanic ethnicity (OR 1.04, 95% CI: 1.01-1.07), treatment at comprehensive community cancer programs (OR 1.06, 95% CI: 1.03-1.08) and integrated network cancer programs (OR 1.55, 95% CI: 1.51-1.59), AJCC stage II (OR 1.06, 95% CI 1.05-1.07) and stage III tumors (OR 1.06, 95% CI: 1.02-1.10), and HR + /HER2 + tumors (OR 1.05, 95% CI: 1.02-1.07). Treatment delay was independently associated with increased risk of mortality (HR 1.23, 95% CI 1.20-1.26), whereas FC (HR 0.87, 95% CI 0.86-0.88) showed survival benefit. CONCLUSIONS: While treatment delay negatively impacts survival in breast cancer patients, our findings suggest FC could be a marker for multispecialty care that may mitigate some of these effects.

ABSTRACT

INTRODUCTION: De-escalation of breast cancer treatment aims to reduce patient and financial toxicity without compromising outcomes. Level I evidence and National Comprehensive Cancer Network guidelines support omission of adjuvant radiation in patients aged >70 y with hormone-sensitive, pT1N0M0 invasive breast cancer treated with endocrine therapy. We evaluated radiation use in patients eligible for guideline concordant omission of radiation. METHODS: Subgroup analysis of patients eligible for radiation omission from two pooled randomized controlled trials, which included stage 0-III breast cancer patients undergoing breast conserving surgery, was performed to evaluate factors associated with radiation use. RESULTS: Of 631 patients, 47 (7.4%) met radiation omission criteria and were treated by 14 surgeons at eight institutions. The mean age was 75.3 (standard deviation + 4.4) y. Majority of patients identified as White (n = 46; 97.9%) and non-Hispanic (n = 44; 93.6%). The mean tumor size was 1.0 cm; 37 patients (88.1%) had ductal, 4 patients (9.5%) had lobular, and 17 patients (40.5%) had low-grade disease. Among patients eligible for radiation omission, 34 (72.3%) patients received adjuvant radiation. Those who received radiation were significantly younger than those who did not (74 y, interquartile range = 4 y, versus 78 y, interquartile range = 11 y, P = 0.03). There was no difference in radiation use based on size (P = 0.4), histology (P = 0.5), grade (P = 0.7), race (P = 1), ethnicity (P = 0.6), institution (P = 0.1), gender of the surgeon (P = 0.7), or surgeon (P = 0.1). CONCLUSIONS: Fewer than 10% of patients undergoing breast conservation met criteria for radiation omission. Nearly three-quarters received radiation therapy with younger age being a driver of radiation use, suggesting ample opportunity for de-escalation, particularly among younger eligible patients.

ABSTRACT

OBJECTIVE: Single-center studies have demonstrated that resection of cavity shave margins (CSM) halves the rate of positive margins and re-excision in breast cancer patients undergoing partial mastectomy (PM). We sought to determine if these findings were externally generalizable across practice settings. METHODS: In this multicenter randomized controlled trial occurring in 9 centers across the United States, stage 0-III breast cancer patients undergoing PM were randomly assigned to either have resection of CSM ("shave" group) or not ("no shave" group). Randomization occurred intraoperatively, after the surgeon had completed their standard PM. Primary outcome measures were positive margin and re-excision rates. RESULTS: Between July 28, 2016 and April 13, 2018, 400 patients were enrolled in this trial. Four patients (2 in each arm) did not meet inclusion criteria after randomization, leaving 396 patients for analysis: 196 in the "shave" group and 200 to the "no shave" group. Median patient age was 65 years (range; 29-94). Groups were well matched at baseline for demographic and clinicopathologic factors. Prior to randomization, positive margin rates were similar in the "shave" and "no shave" groups (76/196 (38.8%) vs. 72/200 (36.0%), respectively, P = 0.604). After randomization, those in the "shave" group were significantly less likely than those in the "no shave" group to have positive margins (19/196 (9.7%) vs. 72/200 (36.0%), P < 0.001), and to require re-excision or mastectomy for margin clearance (17/196 (8.7%) vs. 47/200 (23.5%), P < 0.001). CONCLUSION: Resection of CSM significantly reduces positive margin and re-excision rates in patients undergoing PM.

ABSTRACT

BACKGROUND: Gastric cancer (GC) peritoneal carcinomatosis (PC) is associated with a poor prognosis. Although grade, histology, and stage are associated with PC, the cumulative risk of PC when multiple risk factors are present is unknown. This study aimed to develop a cumulative GCPC risk score based on individual demographic/tumor characteristics. METHODS: Patient-level data (2004-2014) from the California Cancer Registry were reviewed by creating a keyword search algorithm to identify patients with gastric PC. Multivariable logistic regression was used to assess demographic/tumor characteristics associated with PC in a randomly selected testing cohort. Scores were assigned to risk factors based on beta coefficients from the logistic regression result, and these scores were applied to the remainder of the subjects (validation cohort). The summed scores of each risk factor formed the total risk score. These were grouped, showing the percentages of patients with PC. RESULTS: The study identified 4285 patients with gastric adenocarcinoma (2757 males, 64.3%). The median age of the patients was 67 years (interquartile range [IQR], 20 years). Most of the patients were non-Hispanic white (n = 1748, 40.8%), with proximal (n = 1675, 39.1%) and poorly differentiated (n = 2908, 67.9%) tumors. The characteristics most highly associated with PC were T4 (odds ratio [OR], 3.12; 95% confidence interval [CI], 2.19-4.44), overlapping location (OR 2.27; 95% CI 1.52-3.39), age of 20-40 years (OR 3.42; 95% CI 2.24-5.21), and Hispanic ethnicity (OR 1.86; 95% CI 1.36-2.54). The demographic/tumor characteristics used in the risk score included age, race/ethnicity, T stage, histology, tumor grade, and location. Increasing GCPC score was associated with increasing percentage of patients with PC. CONCLUSION: Based on demographic/tumor characteristics in GC, it is possible to distinguish groups with varying odds for PC. Understanding the risk for PC based on the cumulative effect of high-risk features can help clinicians to customize surveillance strategies and can aid in early identification of PC.

ABSTRACT

BACKGROUND: The American College of Surgeons Commission on Cancer has incorporated documentation of critical elements outlined in Operative Standards for Cancer Surgery into revised standards for cancer center accreditation. This study assessed the current documentation of critical elements in partial mastectomy (PM) and sentinel lymph node biopsy (SLNB) operative reports. MATERIALS AND METHODS: Operative reports for PM + SLNB at a single academic institution from 2013 to 2018 were reviewed for compliance and surveyor interobserver reliability with the Oncologic Elements of Operative Record defined in Operative Standards and compared with a nonredundant American Society of Breast Surgeons Mastery of Breast Surgery (MBS) quality measure for specimen orientation. RESULTS: Ten reviewers each evaluated 66 PM + SLNB operative reports for 13 Oncologic Elements and one MBS measure. No operative records reported all critical elements for PM + SLNB or PM alone. Residents completed 36.4% of operative reports: Element documentation was similar for PM but varied significantly for SLNB between resident and attending authorship. Combined reporting performance and interrater reliability varied across all elements and was highest for the use of SLNB tracer (97.1% and κ = 0.95, respectively) and lowest for intraoperative assessment of SLNB (30.6%, κ = 0.43). MBS specimen orientation had both high proportion reported (87.0%) and interrater reliability (κ = 0.84). CONCLUSIONS: Adherence to reporting critical elements for PM and SLNB varied. Whether differential compliance was tied to discrepancies in documentation or reviewer abstraction, clarification of synoptic choices may improve reporting consistency. Evolving techniques or technologies will require continuous appraisal of mandated reporting for breast surgery.

ABSTRACT

BACKGROUND: When microinvasion cannot be ruled out on core needle biopsy (CNB) in the setting of ductal carcinoma in situ (DCIS), the surgeon must decide whether to perform a sentinel lymph node biopsy (SLNB) at the time of surgery. Up to 10 % of patients with T1mi have nodal disease, but the utility of SLNB in DCIS suspicious for microinvasion (Smic) is unclear. METHODS: The University of Chicago pathology database was queried for a diagnosis of Smic or definite microinvasion (Mic) on CNB from 2000 to 2014. We analyzed histology, imaging, core needle size, and the use of myoepithelial immunohistochemistry (IHC) markers. RESULTS: We identified 103 women, 72 with Smic and 31 with Mic on CNB. After surgery, 32 % of Smic patients had infiltrating ductal carcinoma (IDC). Seventy-two percent of Smic patients underwent SLNB, with 67 % performed at the initial surgery. SLNB was positive in 6 % and 10 % of Smic and Mic patients, respectively (p = 0.66). Excluding N1mic, the incidence of macrometastatic nodal disease was 1.9 % for Smic patients and 3.3 % for Mic patients (p = 1.00). For Smic patients, IDC was associated with a larger lesion size and smaller CNB needle. In the setting of Smic, grade, necrosis, or presence of a mass did not increase the risk of IDC. CONCLUSIONS: In patients with Smic on CNB, the incidence of macrometastatic nodal disease after SLNB is rare. Surgeons may consider omitting SLNB until IDC is definitively confirmed, especially in patients with Smic apart from other high-risk features.

ABSTRACT

INTRODUCTION: Sarcopenia is linked to poor outcomes after abdominal surgery. We hypothesized that radiographic sarcopenia metrics enhance prediction of complications after pancreaticoduodenectomy (PD) when combined with clinical and frailty data. METHODS: Preoperative geriatric assessments and CT scans of patients undergoing PD were reviewed. Sarcopenia was assessed at L3 using total psoas area index (TPAI) and weighted average Hounsfield units (HU), i.e., estimates of psoas muscle volume and density. Outcomes included 30-day American College of Surgeons National Surgical Quality Improvement Program (NSQIP) serious complications, Clavien-Dindo complications, unplanned intensive care unit (ICU) admission, hospital length of stay (LOS), non-home facility (NHF) discharge, and readmission rates. RESULTS: Low HU score correlated with NSQIP serious complications (r = -0.31, p = 0.0098), Clavien-Dindo complication grade (r = -0.29, p = 0.0183), unplanned ICU admission (r = -0.28, p = 0.0239), and NHF discharge (r = -0.25, p = 0.0426). Controlling for a "base model" of age, body mass index, American Society of Anesthesiologists score, and comorbidity burden, Fried's exhaustion (odds ratio [OR] 4.72 [1.23-17.71], p = 0.021), and HU (OR 0.88 [0.79-0.98], p = 0.024) predicted NSQIP serious complications. Area under the receiver-operator characteristic (AUC) curves demonstrated that the combination of the base model, exhaustion, and HU trended towards improving the prediction of NSQIP serious complications compared with the base model alone (AUC = 0.81 vs. 0.70; p = 0.09). Additionally, when controlling for the base model, TPAI (ß-coefficient = 0.55 [0.10-1.01], p = 0.018) and exhaustion (ß-coefficient = 2.47 [0.75-4.20], p = 0.005) predicted LOS and exhaustion (OR 4.14 [1.48-11.6], p = 0.007) predicted readmissions. CONCLUSIONS: When combined with clinical and frailty assessments, radiographic sarcopenia metrics enhance prediction of post-PD outcomes.

ABSTRACT

BACKGROUND AND OBJECTIVES: The treatment of patients with pure (<5% round cell component) myxoid liposarcomas (pMLS) has not been well characterized. We hypothesized that multimodality therapy (oncological resection with radiation therapy) may not be necessary for pMLS. METHODS: Patients who underwent resection of localized pMLS at three institutions from 2000 to 2010 were identified and treatment variables were analyzed. RESULTS: Of 75 pts with pMLS, the median tumor size was 10 cm, the majority (95%) were deep tumors, and located in lower extremity. Radiation (XRT) was administered to 58 pts(77%). Comparing the no XRT to XRT patients, lower extremity location (77% vs. 79%, P=1.0), tumor size (13 vs. 11 cm, P=0.3), and positive margins (13% vs. 16%, P=1.0) were similar. The majority (82%) of patients not receiving XRT had deep tumors. After a median follow-up of 60 months, 2 pts (3%) developed local recurrence and 10 pts (13%) developed distant recurrence with a mean recurrence-free survival (RFS) and disease-specific survival (DSS) of 114 and 148 mos, respectively. In multivariate analyses, increasing age and tumor size were the only significant predictors of recurrence. XRT was not a significant predictor of RFS in multivariate analysis. CONCLUSIONS: pMLS is an STS subtype with favorable tumor biology and an extremely low-rate of local recurrence. Our results suggest that multimodality therapy may not be necessary for all pMLS.

ABSTRACT

As surgery grew to become a respected medical profession in the eighteenth century, medical ethics emerged as a response to the growing need to protect patients and maintain the public's trust in physicians. The early influences of John Gregory and Thomas Percival were instrumental in the formulation of patient-centered medical ethics. In the late nineteenth century, the modern surgical advances of anesthesia and antisepsis created the need for a discipline of ethics specific to surgery in order to confront new and evolving ethical issues. One of the founding initiatives of the American College of Surgeons in 1913 was to eliminate unethical practices such as fee-splitting and itinerant surgery. As surgery continued to advance in the era of solid organ transplantation and minimally invasive surgery in the latter half of the twentieth century, surgical innovation and conflict of interest have emerged as important ethical issues moving forward into the twenty-first century. Surgical ethics has evolved into a distinct branch of medical ethics, and the core of surgical ethics is the surgeon-patient relationship and the surgeon's responsibility to advance and protect the well-being of the patient.

ABSTRACT

BACKGROUND: Since 2016, the Choosing Wisely campaign has recommended against routine axillary surgery in elderly patients with early stage, hormone receptor positive (ER+) breast cancer. The objective was to evaluate factors associated with axillary surgery in breast cancer patients meeting criteria for sentinel lymph node biopsy (SLNB) omission and identify potential disparities. METHODS: Female patients age ≥70 years with cT1-2N0M0, ER+, HER2-negative breast cancer diagnosed after publication of the Choosing Wisely recommendations, between 2016 and 2019, were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Patient demographics and tumor characteristics associated with axillary surgery were analyzed. RESULTS: Of the 31 756 patients meeting omission criteria, 25 771 (81.2%) underwent axillary surgery. Hispanic ethnicity, median household income between $35,000 and $70,000, treatment in rural areas, poor differentiation, lobular and mixed lobular with ductal histology, T2 tumors, radiation therapy, and systemic therapy were factors associated with receiving axillary surgery on multivariable analysis. In the axillary surgery cohort, a median of 2 (IQR = 2) nodes were examined and 529 (2.1%) patients were found to have 1 or more positive lymph nodes. DISCUSSION: Among elderly patients meeting Choosing Wisely criteria for SLNB omission, particular racial, ethnic, socioeconomic, and geographic populations may be at increased risk for potential over treatment. Identification of these factors provides specific opportunities for education and implementation of de-escalation of unnecessary procedures.

ABSTRACT

BACKGROUND: For melanoma patients with a positive axillary SLN, the extent of ALND remains controversial, with debate over whether a level III dissection is needed. METHODS: We queried our IRB approved prospective database for patients with a positive axillary SLN who had a level I/II dissection only, and compared recurrence and complication rates to the existing literature. RESULTS: Between 1998 and 2008, 270 patients had 285 level I/II ALNDs for a positive SLN. Median number of SLN removed was 2, while the median number of involved SLN was 1 (range 1-4). An average of 18.7 nodes/ALND were removed, with 13% having positive non-SLN. Post-operative complications occurred in 31 patients (11%), primarily cellulitis (8%). After a mean follow-up of 44 months, 14 patients had a regional recurrence in the axillary basin (5%). CONCLUSIONS: The complication rate and regional recurrence rate for patients undergoing a level I/II ALND for a positive SLN are either lower than or on par with reported series of ALND for level I, II, and III dissections, suggesting that in this setting, the level III dissection may be of minimal benefit.

ABSTRACT

Over the years, the role of B cells in the host immune response to malignancy has been overshadowed by our focus on T cells. Nevertheless, B cells play important roles as antigen-presenting cells and in the production of antibodies. Furthermore, B cells can function as effector cells that mediate tumor destruction on their own. This review will highlight the various functions of B cells that are involved in the host response to tumor.

ABSTRACT

BACKGROUND: Molecular subtype in invasive breast cancer guides systemic therapy. It is unknown whether molecular subtype should also be considered to tailor surgical therapy. The present investigation was designed to evaluate whether breast cancer subtype impacted surgical margins in patients with invasive breast cancer stage I through III undergoing breast-conserving therapy. METHODS: Data from 2 randomized trials evaluating cavity shave margins (CSM) on margin status in patients undergoing partial mastectomy (PM) were used for this analysis. Patients were included if invasive carcinoma was present in the PM specimen and data for all 3 receptors (ER, PR, and HER2) were known. Patients were classified as luminal if they were ER and/or PR positive; HER2 enriched if they were ER and PR negative but HER2 positive; and TN if they were negative for all 3 receptors. The impact of subtype on the margin status was evaluated at completion of standard PM, prior to randomization to CSM versus no CSM. Non-parametric statistical analyses were performed using SPSS Version 26. RESULTS: Molecular subtype was significantly correlated with race (P = .011), palpability (P = .007), and grade (P < .001). Subtype did not correlate with Hispanic ethnicity (P = .760) or lymphovascular invasion (P = .756). In this cohort, the overall positive margin rate was 33.7%. This did not vary based on molecular subtype (positive margin rate 33.7% for patients with luminal tumors vs 36.4% for those with TN tumors, P = .425). DISCUSSION: Molecular subtype does not predict margin status. Therefore, molecular subtype should not, independent of other factors, influence surgical decision-making.

ABSTRACT

INTRODUCTION: Factors contributing to the use of preoperative MRI remain poorly understood. METHODS: Data from a randomized controlled trial of stage 0-3 breast cancer patients undergoing breast conserving surgery between 2016 and 2018 were analyzed. RESULTS: Of the 396 patients in this trial, 32.6% had a preoperative MRI. Patient age, race, ethnicity, tumor histology, and use of neoadjuvant therapy were significant predictors of MRI use. On multivariate analysis, younger patients with invasive lobular tumors were more likely to have a preoperative MRI. Rates also varied significantly by individual surgeon (p < 0.001); in particular, female surgeons (39.9% vs. 24.0% for male surgeons, p = 0.001) and those in community practice (58.9% vs. 14.2% for academic, p < 0.001) were more likely to order preoperative MRI. Rates declined over the two years of the study, particularly among female surgeons. CONCLUSIONS: Preoperative MRI varies with patient age and tumor histology; however, there remains variability by individual surgeon.

ABSTRACT

BACKGROUND: We sought to determine factors affecting time to surgery (TTS) to identify potential modifiable factors to improve timeliness of care. METHODS: Patients with clinical stage 0-3 breast cancer undergoing partial mastectomy in 2 clinical trials, conducted in ten centers across the US, were analyzed. No preoperative workup was mandated by the study; those receiving neoadjuvant therapy were excluded. RESULTS: The median TTS among the 583 patients in this cohort was 34 days (range: 1-289). Patient age, race, tumor palpability, and genomic subtype did not influence timeliness of care defined as TTS ≤30 days. Hispanic patients less likely to have a TTS ≤30 days (P = .001). There was significant variation in TTS by surgeon (P < .001); those practicing in an academic center more likely to have TTS ≤30 days than those in a community setting (55.1% vs 19.3%, P < .001). Patients who had a preoperative ultrasound had a similar TTS to those who did not (TTS ≤30 days 41.9% vs 51.9%, respectively, P = .109), but those who had a preoperative MRI had a significantly increased TTS (TTS ≤30 days 25.0% vs 50.9%, P < .001). On multivariate analysis, patient ethnicity was no longer significantly associated with TTS ≤30 (P = .150). Rather, use of MRI (OR: .438; 95% CI: .287-.668, P < .001) and community practice type (OR: .324; 95% CI: .194-.541, P < .001) remained independent predictors of lower likelihood of TTS ≤30 days. CONCLUSIONS: Preoperative MRI significantly increases time to surgery; surgeons should consider this in deciding on its use.

ABSTRACT

Importance: The suspension of elective operations in March 2020 to prepare for the COVID-19 surge posed significant challenges to resident education. To mitigate the potential negative effects of COVID-19 on surgical education, it is important to quantify how the pandemic influenced resident operative volume. Objective: To examine the association of the pandemic with general surgical residents' operative experience by postgraduate year (PGY) and case type and to evaluate if certain institutional characteristics were associated with a greater decline in surgical volume. Design, Setting, and Participants: This retrospective review included residents' operative logs from 3 consecutive academic years (2017-2018, 2018-2019, and 2019-2020) from 16 general surgery programs. Data collected included total major cases, case type, and PGY. Faculty completed a survey about program demographics and COVID-19 response. Data on race were not collected. Operative volumes from March to June 2020 were compared with the same period during 2018 and 2019. Data were analyzed using Kruskal-Wallis test adjusted for within-program correlations. Main Outcome and Measures: Total major cases performed by each resident during the first 4 months of the pandemic. Results: A total of 1368 case logs were analyzed. There was a 33.5% reduction in total major cases performed in March to June 2020 compared with 2018 and 2019 (45.0 [95% CI, 36.1-53.9] vs 67.7 [95% CI, 62.0-72.2]; P < .001), which significantly affected every PGY. All case types were significantly reduced in 2020 except liver, pancreas, small intestine, and trauma cases. There was a 10.2% reduction in operative volume during the 2019-2020 academic year compared with the 2 previous years (192.3 [95% CI, 178.5-206.1] vs 213.8 [95% CI, 203.6-223.9]; P < .001). Level 1 trauma centers (49.5 vs 68.5; 27.7%) had a significantly lower reduction in case volume than non-level 1 trauma centers (33.9 vs 63.0; 46%) (P = .03). Conclusions and Relevance: In this study of operative logs of general surgery residents in 16 US programs from 2017 to 2020, the first 4 months of the COVID-19 pandemic was associated with a significant reduction in operative experience, which affected every PGY and most case types. Level 1 trauma centers were less affected than non-level 1 centers. If this trend continues, the effect on surgical training may be even more detrimental.

ABSTRACT

BACKGROUND: Resident evaluation of faculty teaching is an important metric in general surgery training, however considerable variability in faculty teaching evaluation (FE) instruments exists. STUDY DESIGN: Twenty-two general surgery programs provided their FE and program demographics. Three clinical education experts performed blinded assessment of FEs, assessing adherence 2018 ACGME common program standards and if the FE was meaningful. RESULTS: Number of questions per FE ranged from 1 to 29. The expert assessments demonstrated that no evaluation addressed all 5 ACGME standards. There were significant differences in the FEs effectiveness of assessing the 5 ACGME standards (p < 0.001), with teaching abilities and professionalism rated the highest and scholarly activities the lowest. CONCLUSION: There was wide variation between programs regarding FEs development and adhered to ACGME standards. Faculty evaluation tools consistently built around all suggested ACGME standards may allow for a more accurate and useful assessment of faculty teaching abilities to target professional development.

ABSTRACT

OBJECTIVE: Non-designated preliminary (NDP) general surgery residents face the daunting challenge of obtaining a categorical residency position while undertaking the rigors of a general surgery residency. This additional application cycle represents a stressful time for these trainees and limited data exists to help guide applicants and program directors regarding the factors predictive of application success. While previous studies have focused solely on applicant related factors, no study to date has evaluated the effect of the residency program structure, institutional resources, or administrative support on these outcomes. DESIGN/SETTING: A multicenter retrospective review of 10 general surgery residency programs over a 5-year period from 2014 to 2019 was performed. Applicant related information was compiled from NDP general surgery residents and the results of their attempted second application into a categorical position. Applicant factors including age, gender, standardized test scores (USMLE/ABSITE), and professional training were examined. Program and administrative structure including residency class size, number of NDP PGY-2 positions, number of assistant program directors and program director (PD) background were also examined. Primary success was defined as a NDP resident successfully obtaining a categorical position within general surgery or a surgical subspecialty. Secondary success was obtaining a categorical residency position in any field of medical practice other than surgery or a surgical subspecialty in the United States. RESULTS: A total of 260 NDP trainees were evaluated with an average age of 29.1. Almost seventy percent of applicants were male, 40% graduated from a non-U.S. medical school and 24.2% required a visa to work in the United States. Thirty 4 percent of NDPs successfully obtained a categorical surgery position and an additional 35% obtained a categorical residency position in a nonsurgical field for an overall match success rate of 68.9%. Factors associated with primary success included ABSITE score (p < 0.001), US medical school graduation (p = 0.02), visa status (p = 0.03), presence of preliminary PGY-2 positions (p = 0.02), and PD professional development time (p = 0.004). Overall success was associated USMLE Step 1 scores (p = 0.02), number of approved chiefs (p = 0.03), presence of dedicated faculty researchers (p = 0.001), and PD professional development time (p < 0.001). CONCLUSIONS: Applicant, program-related, and administrative factors all have a significant impact on the success of NDP general surgery residents in obtaining a categorical surgical position. Trainees should consider all of these factors when applying to NDP residencies and in approaching their second application cycle to maximize their likelihood of a successful match.
