RESUMEN

INTRODUCTION: Diversity in medicine has a positive effect on outcomes, especially for Asian patients. We sought to evaluate representation of Asians across entry and leadership levels in surgical training. METHODS: Publicly accessible population data from 2018 to 2023 were collected from the US Census Bureau, the Association of American Medical Colleges, and the American Board of Surgery (ABS). Frequencies based on self-identified Asian status were identified, and proportions were calculated. RESULTS: The US census showed Asians constituted 4.9% of the US population in 2018 versus 6% in 2023. The proportion of Asian medical students rose from 21.6% to 24.8%; however, Asian surgical residency applicants remained constant at 20%. ABS certifications of Asians have increased from 13.7% to 18.5%. ABS examiners increased from 15.7% to 17.1%. CONCLUSIONS: In 5 years, Asians have made numeric gains in medical school and surgical training. However, Asian representation lags at Board examiner levels compared to the medical student population. The ABS has made recent efforts at transparency around examiner and examinee characteristics. A pillar of ensuring a well-trained surgical workforce to serve the public is to mandate that all surgical trainees and graduates undergo fair examinations, and are fairly assessed on their qualifications. Observed progress should further invigorate all surgical applicants, residents and leadership to take an even more active role in making surgery more diverse and welcoming to all, by including careful analyses of diversity at all levels.

RESUMEN

BACKGROUND: The relationship between hospital volume and surgical mortality is well documented. However, complete centralization of surgical care is not always feasible. The present study investigates how overall volume of upper gastrointestinal surgery at hospitals influences patient outcomes following resection for gastric adenocarcinoma. PATIENTS AND METHODS: National Cancer Database (2010-2019) patients with pathologic stage 1-3 gastric adenocarcinoma who underwent gastrectomy were identified. Three cohorts were created: low-volume hospitals (LVH) for both gastrectomy and overall upper gastrointestinal operations, mixed-volume hospital (MVH) for low-volume gastrectomy but high-volume overall upper gastrointestinal operations, and high-volume gastrectomy hospitals (HVH). Chi-squared tests were used to analyze sociodemographic factors and surgical outcomes and Kaplan-Meier method for survival analysis. RESULTS: In total, 26,398 patients were identified (LVH: 20,099; MVH: 539; HVH: 5,760). The 5-year survival was equivalent between MVH and HVH for all stages of disease (MVH: 56.0%, HVH 55.6%; p = 0.9866) and when stratified into early (MVH: 69.9%, HVH: 65.4%; p = 0.1998) and late stages (MVH: 24.7%, HVH: 32.0%; p = 0.1480), while LVH had worse survival. After matching patients, postoperative outcomes were worse for LVH, but there was no difference between MVH and HVH in terms of adequate lymphadenectomy, margin status, readmission rates, and 90-day mortality rates. CONCLUSIONS: Despite lower gastrectomy volume for cancer, postoperative gastrectomy outcomes at centers that perform a high number of upper gastrointestinal cancer surgeries were similar to hospitals with high gastrectomy volume. These hospitals offer a blueprint for providing equivalent outcomes to high volume centers while enhancing availability of quality cancer care.

RESUMEN

BACKGROUND: Timely treatment for patients with colorectal cancer may have been disrupted by the COVID-19 pandemic. We evaluated the impact of the pandemic on delays to treatment with surgery or systemic therapy for patients with colorectal cancer and delineated factors predictive of delayed treatment. METHODS: Using the National Cancer Database, patients diagnosed with colorectal cancer were categorized by year of diagnosis as COVID-19 era (2020) versus pre-COVID-19 (2018-2019). Categorical variables were compared by χ2 analysis. Multivariate logistic regression was used to assess odds ratios for delayed time to surgery or chemoimmunotherapy, defined as >60 days. RESULTS: In total, 50,689 patients colorectal cancer were diagnosed patients who were pre-COVID-19 vs 21,331 within the COVID-19-era. Patients diagnosed with COVID-19 had a higher stage at diagnosis. There were no differences in the proportion of delayed time to surgery for patients diagnosed in 2020, but patients who were tested for COVID-19 had increased proportions of delayed time to surgery (P < .0001). In multivariate analysis, Black race (P = .0026) and uninsured/underinsured status (P = .0017) were associated with delayed time to surgery. Diagnosis during COVID-19 did not increase delayed time to chemoimmunotherapy, regardless of COVID-19 testing or positivity; however, delays were seen for Black (P < .0001), Hispanic (P < .0001), and uninsured/underinsured patients (P < .0001). CONCLUSION: Although the pandemic did not delay treatment for colorectal cancer overall, vulnerable and underserved populations were disproportionately affected by delays to all forms of therapy. The difference in colorectal cancer outcomes in the coming years as a result of delays in treatment may be significant for these patients.

RESUMEN

BACKGROUND: Minimally invasive pancreaticoduodenectomy (MIPD), including robotic (RPD) and laparoscopy (LPD), is becoming more frequently employed in the management of pancreatic ductal adenocarcinoma (PDAC), though the majority of operations are still performed via open approach (OPD). Access to technologic advances often neglect the underserved. Whether disparities in access to MIPD exist, remain unclear. METHODS: The National Cancer Database (NCDB) was queried (2010-2020) for patients who underwent pancreatoduodenectomy for PDAC. Cochran-Armitage tests assessed for trends over time. Social determinants of health (SDH) were compared between approaches. Multinomial logistic models identified predictors of MIPD. RESULTS: Of 16,468 patients, 80.03 % underwent OPD and 19.97 % underwent MIPD (22.60 % robotic; 77.40 % laparoscopic). Black race negatively predicted LPD (vs white (OR 0.822; 95 % CI 0.701-0.964)). Predictors of RPD included Medicare/other government insurance (vs uninsured or Medicaid (OR 1.660; 95 % CI 1.123-2.454)) and private insurance (vs uninsured or Medicaid (OR 1.597; 95 % CI 1.090-2.340)). Early (2010-2014) vs late (2015-2020) diagnosis, stratified by race, demonstrated an increase in Non-White patients undergoing OPD (13.15 % vs 14.63 %; p = 0.016), but not LPD (11.41 % vs 13.57 %;p = 0.125) or RPD (14.15 % vs 15.23 %; p = 0.774). CONCLUSION: SDH predict surgical approach more than clinical stage, facility type, or comorbidity status. Disparities in race and insurance coverage are different between surgical approaches.

RESUMEN

INTRODUCTION: Initial treatment for nonmetastatic breast cancer is resection or neoadjuvant systemic therapy, depending on tumor biology and patient factors. Delays in treatment have been shown to impact survival and quality of life. Little has been published on the performance of safety-net hospitals in delivering timely care for all patients. METHODS: We conducted a retrospective study of patients with invasive ductal or lobular breast cancer, diagnosed and treated between 2009 and 2019 at an academic, safety-net hospital. Time to treatment initiation was calculated for all patients. Consistent with a recently published Committee on Cancer timeliness metric, a treatment delay was defined as time from tissue diagnosis to treatment of greater than 60 days. RESULTS: A total of 799 eligible women with stage 1-3 breast cancer met study criteria. Median age was 60 years, 55.7% were non-white, 35.5% were non-English-speaking, 18.9% were Hispanic, and 49.4% were Medicaid/uninsured. Median time to treatment was 41 days (IQR 27-56 days), while 81.1% of patients initiated treatment within 60 days. The frequency of treatment delays did not vary by race, ethnicity, insurance, or language. Diagnosis year was inversely associated with the occurrence of a treatment delay (OR: 0.944, 95% CI 0.893-0.997, p value: 0.039). CONCLUSION: At our institution, race, ethnicity, insurance, and language were not associated with treatment delay. Additional research is needed to determine how our safety-net hospital delivered timely care to all patients with breast cancer, as reducing delays in care may be one mechanism by which health systems can mitigate disparities in the treatment of breast cancer.

RESUMEN

Eccrine porocarcinoma is a rare malignant tumor of the eccrine sweat gland. This malignancy occurs most commonly in the lower extremities. It tends to occur in patients aged 60 to 80 years, affecting men and women equally. We present the case of a 62-year-old man with a lesion on the left foot. The diagnosis of the initial biopsy was squamous cell carcinoma. Six months later, the lesion reoccurred, and a second biopsy confirmed it to be eccrine porocarcinoma.

RESUMEN

BACKGROUND: Adherence to current recommendations for optimal time from diagnosis to treatment for patients with breast cancer may have been disrupted by the COVID-19 pandemic. This study aimed to evaluate the impact of the pandemic on time to surgery or systemic treatment with chemotherapy or immunotherapy for patients diagnosed with breast cancer. METHODS: Using the National Cancer Database, patients diagnosed with breast cancer in 2020 were compared to those diagnosed from 2018-2019 (Pre-COVID). Sub-analyses were performed for patients who were tested for COVID-19 and those who had a positive result in 2020. Multivariate logistic regression was used assess odds ratios for delayed time to surgery (DTS, defined as > 90 days) or systemic therapy (defined as > 120 days). RESULTS: In total, 230,997 patients were diagnosed with breast cancer in 2018 and 2019 compared to 102,065 in 2020. Of the 2020 cohort, 47,659 (46.7%) received COVID-19 testing; of which, 3,158 (6.6%) resulted positive. A larger proportion of COVID-tested or COVID-positive patients had higher stage at diagnosis. DTS was more likely for patients who were diagnosed in 2020, uninsured or underinsured, non-white, Hispanic, less educated, or age < 70 years. Similar factors were predictive of delay to systemic therapy (less age < 70 years); however, diagnosis in 2020 was not. CONCLUSION: The COVID-19 pandemic was associated with significant DTS for breast cancer but spared time to systemic therapy. Delays disproportionately impacted vulnerable and underserved patient populations. The true clinical effects of these delays may yet be realized for breast cancer patients.

RESUMEN

INTRODUCTION: Breast-conserving therapy (BCT), specifically breast-conserving surgery (BCS) and adjuvant radiation, provides an equivalent alternative to mastectomy for eligible patients. However, previous studies have shown that BCT is underused in the United States, particularly among marginalized demographic groups. In this study, we examine the association between race, ethnicity, insurance, and language and rate of BCS among patients treated at an academic, safety-net hospital. MATERIALS AND METHODS: We conducted a retrospective cohort study of 520 women with nonmetastatic breast cancer diagnosed and treated at an academic, safety-net hospital (2009-2014). We assessed eligibility for BCT and then differences in the rate of BCT among eligible patients by race, ethnicity, insurance, and language. Reasons for not undergoing BCT were documented. RESULTS: Median age was 60 y; 55.9% were non-White, 31.9% were non-English-speaking, 15.6% were Hispanic, and 47.4% were Medicaid/uninsured. Three hundred seventy one (86.3%) underwent BCS; within this group, 324 (87.3%) completed adjuvant radiation. Among patients undergoing mastectomy, 30 patients (36.7%) were eligible for BCT; within this group, reasons for mastectomy included patient preference (n = 28) and to avoid possible re-excision or adjuvant radiation in patients with significant comorbidities (n = 2). Eligibility for BCT varied by ethnicity (Hispanic [100%], Non-Hispanic [92%], P = 0.02), but not race, language, or insurance. Among eligible patients, rate of BCS varied by age (<50 y [84.9%], ≥50 y [92.9%], P = 0.01) and ethnicity (Hispanic [98.5%], Non-Hispanic [91.3%], P = 0.04), but not race, language, or insurance. CONCLUSIONS: At our safety-net hospital, the rate of BCS among eligible patients did not vary by race, language, or insurance. Excluding two highly comorbid patients, all patients who underwent mastectomy despite being eligible for BCT were counseled regarding BCS and expressed a preference for mastectomy. Further research is needed to understand the value of BCT in the treatment of breast cancer, to ensure informed decision-making, address potential misconceptions regarding BCT, and advance equitable care for all patients.

RESUMEN

INTRODUCTION: Patients with pancreatic cancer can present with a variety of insidious abdominal symptoms, complicating initial diagnosis. Early symptoms of pancreatic cancer often mirror those associated with gallstone disease, which has been demonstrated to be a risk factor for this malignancy. This study aims to compare the incidence of gallstone disease in the year before diagnosis of pancreatic ductal adenocarcinoma (PDAC) as compared to the general population, and evaluate the association of gallstone disease with stage at diagnosis and surgical intervention. METHODS: Patients with PDAC were identified from SEER-Medicare (2008-2015). The incidence of gallstone disease (defined as cholelithiasis, cholecystitis and/or cholecystectomy) in the 1 year before cancer diagnosis was compared to the annual incidence in an age-matched, sex-matched, and race-matched noncancer Medicare cohort. RESULTS: Among 14,654 patients with PDAC, 4.4% had gallstone disease in the year before cancer diagnosis. Among the noncancer controls (n = 14,654), 1.9% had gallstone disease. Both cohorts had similar age, sex and race distributions. PDAC patients with gallstone disease were diagnosed at an earlier stage (stage 0/I-II, 45.8% versus 38.1%, P < 0.0001) and a higher proportion underwent resection (22.7% versus 17.4%, P = 0.0004) compared to patients without gallstone disease. CONCLUSIONS: In the year before PDAC diagnosis, patients present with gallstone disease more often than the general population. Improving follow-up care and differential diagnosis strategies may help combat the high mortality rate in PDAC by providing an opportunity for earlier stage of diagnosis and earlier intervention.

RESUMEN

BACKGROUND: Vulnerable populations have worse hepatocellular carcinoma (HCC) outcomes. We sought to understand if this could be mitigated at a safety-net hospital. METHODS: A retrospective chart review of HCC patients was conducted (2007-2018). Stage at presentation, intervention and systemic therapy were analyzed (Chi-square for categorical variables and Wilcoxon tests for continuous variables) and median survival calculated by Kaplan-Meier method. RESULTS: 388 HCC patients were identified. Sociodemographic factors were similar for stage at presentation, except insurance status (diagnosis at earlier stages for commercial insurance and later stages for safety-net/no insurance). Higher education level and origin of mainland US increased intervention rates for all stages. Early-stage disease patients had no differences in receipt of intervention or therapy. Late-stage disease patients with higher education level had increased intervention rates. Median survival was not impacted by any sociodemographic factor. CONCLUSION: Urban safety-net hospitals with a focus on vulnerable patient populations provide equitable outcomes and can serve as a model to address inequities in HCC management.

RESUMEN

BACKGROUND: We previously demonstrated the importance of combined complex surgery volume on short-term outcomes of high-risk cancer operations. This study investigates the impact of combined common complex cancer operation volume on long-term outcomes at hospitals with low cancer-specific operation volumes. PATIENTS AND METHODS: A retrospective cohort of National Cancer Data Base (2004-2019) patients undergoing surgery for hepatocellular carcinoma, non-small cell lung cancers, or pancreatic, gastric, esophageal, or rectal adenocarcinomas was utilized. Three separate cohorts were established: low-volume hospitals (LVH), mixed-volume hospitals (MVH) with low-volume individual cancer operations and high-volume total complex operations, and high-volume hospitals (HVH). Survival analyses were performed for overall, early-, and late-stage disease. RESULTS: The 5 year survival was significantly better at MVH and HVH compared with LVH, for all operations except late-stage hepatectomy (HVH survival > LVH and MVH). The 5 year survival probability was similar between MVH and HVH for operations on late-stage cancers. Early and overall survival for gastrectomy, esophagectomy, and proctectomy were equivalent between MVH and HVH. While early and overall survival for pancreatectomy were benefited by HVH over MVH, the opposite was true for lobectomy/pneumonectomy, which were benefited by MVH over HVH; however, none of these differences were likely to have an effect clinically. Only hepatectomy patients demonstrated statistical and clinical significance in 5 year survival at HVH compared with MVH for overall survival. CONCLUSIONS: MVH hospitals performing sufficient complex common cancer operations demonstrate similar long-term survival for specific high-risk cancer operations to HVH. MVH provide an adjunctive model to the centralization of complex cancer surgery, while maintaining quality and access.

RESUMEN

We present a distinctive case of solid pseudopapillary neoplasm as seen in a 44-year-old woman who presented with an abdominal mass but unremarkable labs with no elevation in any of the tumor markers. Her symptomatology ranged from typical symptoms suggestive of malignancy such as weight loss, lethargy, and anorexia to complaints like abdominal pain and jaundice. Prior to presenting at our center, she was given no hope or much in terms of treatment options. She was found to have a substantial mass over the body and tail of pancreas with characteristic and typical gross as well as histological features. Subsequently, she underwent a successful surgery and has found herself in remission since.

RESUMEN

BACKGROUND: Male breast cancer (MBC) is rare, and management is extrapolated from trials that enroll only women. It is unclear whether contemporary axillary management based on data from landmark trials in women may also apply to men with breast cancer. This study aimed to compare survival in men with positive sentinel lymph nodes after sentinel lymph node biopsy (SLNB) alone versus complete axillary dissection (ALND). PATIENTS AND METHODS: Using the National Cancer Database, men with clinically node-negative, T1 and T2 breast cancer and 1-2 positive sentinel nodes who underwent SLNB or ALND were identified from 2010 to 2020. Both 1:1 propensity score matching and multivariate regression were used to identify patient and disease variables associated with ALND versus SLNB. Survival between ALND and SLNB were compared using Kaplan-Meier methods. RESULTS: A total of 1203 patients were identified: 61.1% underwent SLNB alone and 38.9% underwent ALND. Treatment in academic centers (36.1 vs. 27.7%; p < 0.0001), 2 positive lymph nodes on SLNB (32.9 vs. 17.3%, p < 0.0001) and receipt or recommendation of chemotherapy (66.5 vs. 52.2%, p < 0.0001) were associated with higher likelihood of ALND. After propensity score matching, ALND was associated with superior survival compared with SLNB (5-year overall survival of 83.8 vs. 76.0%; log-rank p = 0.0104). DISCUSSION: The results of this study suggest that among patients with early-stage MBC with limited sentinel lymph node metastasis, ALND is associated with superior survival compared with SLNB alone. These findings indicate that it may be inappropriate to extrapolate the results of the ACOSOG Z0011 and EORTC AMAROS trials to MBC.
