ABSTRACT

BACKGROUND: High-risk patients undergoing abdominoperineal resection and pelvic exenteration may benefit from immediate flap reconstruction. However, there is currently no consensus on the ideal flap choice or patient for whom this is necessary. This study aimed to evaluate the long-term outcomes of using pedicled gracilis flaps for pelvic reconstruction and to analyze predictors of postoperative complications. METHODS: This was a retrospective review of a single reconstructive surgeon's cases between January 2012 and June 2021 identifying patients who underwent perineal reconstruction secondary to oncologic resection. Preoperative and outcome variables were collected and analyzed to determine the risk of developing minor and major wound complications. RESULTS: A total of 101 patients were included in the study with most patients (n = 88) undergoing unilateral gracilis flap reconstruction after oncologic resection. The mean follow-up period was 75 months. Of 101 patients, 8 (7.9%) developed early major complications, and an additional 13 (12.9%) developed late major complications. Minor complications developed in 33 patients (32.7%) with most cases being minor wound breakdown requiring local wound care. Most patients (n = 92, 91.1%) did not develop donor site complications. Anal cancer was significantly associated with early major complications, whereas younger age and elevated body mass index were significant predictors of developing minor wound complications. CONCLUSIONS: This study builds on our previous work that demonstrated the long-term success rate of gracilis flap reconstruction after large pelvic oncologic resections. A few patients developed donor site complications, and perineal complications were usually easily managed with local wound care, thus making the gracilis flap an attractive alternative to abdominal-based flaps.

ABSTRACT

Global health is an evolving field that has been broadly defined as the promotion of health for all through transnational collaboration and research. It centers on the concepts of equity and collaboration. The focus of global health has recently undergone a major shift toward emphasizing the importance of a systems-based approach to healthcare delivery, which considers not only the target disease but also the many contextual factors, influencing the ability to deliver care equitably to a population to reduce the burden of any particular disease. Thus, an important global health delivery framework has been established to outline this inter- and multi-disciplinary systems-based to address major global health issues and improve health for all globally. The practice of global health, whether in research or in active intervention, necessitates guiding principles to ensure ethical conduct in the transnational partnerships and efforts to advance the field. With the introduction of the United Nations' Sustainable Development Goals in 2015, there has been a major shift in response to epidemiologic transition to focus on reducing the burden of noncommunicable diseases, including cancer, which disproportionately impact low-to-middle income countries. This is true for colorectal cancer, with care challenged by significant gaps in screening, early detection, and referral systems.

ABSTRACT

BACKGROUND: In Ukraine, there is no established colorectal cancer screening program. We aimed to project the number of screening colonoscopies needed for implementation of various CRC screening strategies in Ukraine. METHODS: We modified a previously developed Markov microsimulation model to reflect the natural history of adenoma and CRC progression among average-risk 50-74-year-olds. We simulated colonoscopies needed for the following screening strategies: no screening, fecal occult blood test yearly, FOBT yearly with flexible sigmoidoscopy every 5 years, FS every 5 years, fecal immunohistochemistry test (FIT) yearly, or colonoscopy every 10 years. Assuming 80% screening adherence, we estimated colonoscopies required at 1 and 5 years depending on the implementation rate. In one-way sensitivity analyses, we varied implementation rate, screening adherence, sensitivity, and specificity. RESULTS: Assuming an 80% screening adherence and complete implementation (100%), besides a no screening strategy, the fewest screening colonoscopies are needed with an FOBT program, requiring on average 6,600 and 26,800 colonoscopies per 100,000 persons at 1 and 5 years post-implementation, respectively. The most screening colonoscopies are required with a colonoscopy program, requiring on average 76,600 and 101,000 colonoscopies per 100,000 persons at 1 and 5 years post-implementation, respectively. In sensitivity analyses, the biggest driver of number of colonoscopies needed was screening adherence. CONCLUSIONS: The number of colonoscopies needed and therefore the potential strain on the healthcare system vary substantially by screening test. These findings can provide valuable information for stakeholders on equipment needs when implementing a national screening program in Ukraine.

ABSTRACT

Colorectal cancer with peritoneal involvement is traditionally recognized as having a poor prognosis, with treatment initially limited to palliative systemic chemotherapy alone. The introduction of cytoreductive surgery (CRS) in combination with hyperthermic intraperitoneal chemotherapy drastically altered the course of this disease entity and has demonstrated improvements in survival outcomes. Recent evidence has shown benefit of CRS but did not show benefit of HIPEC. Under the guidance of a multidisciplinary team and for appropriately selected patients, CRS is a key component of treatment that can positively alter the course of disease outcomes for patients with peritoneal involvement.

ABSTRACT

Gender bias is a pervasive issue in academic surgery and is characterized by familiar patterns previously described in the business world. In this article, the authors illuminate gender bias patterns in academic surgery identified in prior in-depth interviews with female surgical department chairs across the United States. The 4 main gender bias patterns drawn from the business world and illuminated with data from the interviews are (1) prove-it-again, (2) tightrope or double-blind dilemma, (3) maternity wall or benevolent bias, and (4) tug-of-war. The authors propose steps to disrupt systemic gender bias issues recognized in the academic surgery community. The proposed steps are informed by guidance from surgical diversity task forces, by existing literature, and by the authors' own experiences in the field. The steps are divided into 3 main categories: education, structured mentorship, and transparency. The proposed changes include improving training and recognition of unconscious bias, establishing level-appropriate and deliberate mentorship across all stages of training and practice, standardizing promotional requirements, and eliminating outdated standards that contribute to the gender pay gap. Although this article addresses gender bias in academic surgery, the proposed steps toward change can promote equity across the surgical community as a whole and extend to other underrepresented groups in the field.

ABSTRACT

BACKGROUND: Malignant peritoneal mesothelioma is a rare disease with poor outcomes. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is the cornerstone of therapy. We aim to compare outcomes of malignant peritoneal mesothelioma treated at academic versus community hospitals. METHODS: This was a retrospective cohort study using the National Cancer Database to identify patients with malignant peritoneal mesothelioma from 2004 to 2016. Patients were divided according to treating facility type: academic or community. Outcomes were assessed using log-rank tests, Cox proportional-hazard modeling, and Kaplan-Meier survival statistics. RESULTS: In total, 2682 patients with malignant peritoneal mesothelioma were identified. A total of 1272 (47.4%) were treated at an academic facility and 1410 (52.6%) were treated at a community facility. Five hundred forty-six (42.9%) of patients at academic facilities underwent debulking or radical surgery compared to 286 (20.2%) at community facilities. Three hundred sixty-six (28.8%) of patients at academic facilities received chemotherapy on the same day as surgery compared to 147 (10.4%) of patients at community facilities. Unadjusted 5-year survival was 29.7% (95% CI 26.7-32.7) for academic centers compared to 18.3% (95% CI 16.0-20.7) for community centers. In multivariable analysis, community facility was an independent predictor of increased risk of death (HR: 1.19, 95% CI 1.08-1.32, p = 0.001). CONCLUSIONS: We demonstrate better survival outcomes for malignant peritoneal mesothelioma treated at academic compared to community facilities. Patients at academic centers underwent surgery and received chemotherapy on the same day as surgery more frequently than those at community centers, suggesting that malignant peritoneal mesothelioma patients may be better served at experienced academic centers.

ABSTRACT

BACKGROUND: Prior studies assessing colorectal cancer survival have reported better outcomes when operations are performed at high-volume centers. These studies have largely been cross-sectional, making it difficult to interpret their estimates. We aimed to assess the effect of facility volume on survival following proctectomy for rectal cancer. METHODS: Using data from the National Cancer Database, we included all patients with complete baseline information who underwent proctectomy for non-metastatic rectal cancer between 2004 and 2016. Facility volume was defined as the number of rectal cancer cases managed at the treating center in the calendar year prior to the patient's surgery. Overall survival estimates were obtained for facility volumes ranging from 10 to 100 cases/year. Follow-up began on the day of surgery and continued until loss to follow-up or death. RESULTS: A total of 52,822 patients were eligible. Patients operated on at hospitals with volumes of 10, 30, and 50 cases/year had similar distributions of grade, clinical stage, and neoadjuvant therapies. 1-, 3-, and 5-year survival all improved with increasing facility volume. One-year survival was 94.0% (95% CI: 93.7, 94.3) for hospitals that performed 10 cases/year, 94.5% (95% CI: 94.2, 94.7) for 30 cases/year, and 94.8% (95% CI: 94.5, 95.0) for 50 cases/year. Five-year survival was 68.9% (95% CI: 68.0, 69.7) for hospitals that performed 10 cases/year, 70.8% (95% CI: 70.1, 71.5) for 30 cases/year, and 72.0% (95% CI: 71.2, 72.8) for 50 cases/year. CONCLUSIONS: Treatment at a higher volume facility results in improved survival following proctectomy for rectal cancer, though the small benefits are less profound than previously reported.

ABSTRACT

BACKGROUND: The incidence of anal squamous cell carcinoma (SCC) is rising, despite the introduction of a vaccine against human papillomavirus (HPV), the most common etiology of anal SCC. The rate of anal SCC is higher among women and sex-based survival differences may exist. We aimed to examine the association between sex and survival for stage I-IV anal SCC. MATERIALS AND METHODS: The National Cancer Database was used to identify patients with stage I-IV anal SCC from 2004-2016. Outcomes were assessed utilizing log rank tests, Kaplan-Meier statistics, and Cox proportional-hazard modeling. Subgroup analyses by disease stage and by HPV status were performed. Outcomes of interest were median, 1-, and 5-year survival by sex. RESULTS: There were 31,185 patients with stage I-IV anal SCC. 10,714 (34.3%) were male and 20,471 (65.6%) were female. 1- and 5- year survival was 90.2% (95% CI 89.8 - 90.7) and 67.7% (95% CI 66.9 - 68.5) for females compared to 85.8% (95% CI 85.1 - 86.5) and 55.9% (95% CI 54.7 - 57.0) for males. In subgroup analysis, females demonstrated improved unadjusted and adjusted survival for all stages of disease. Female sex was an independent predictor of improved survival (HR 0.68, 95% CI 0.65 - 0.71, P < 0.001). CONCLUSIONS: We demonstrate better overall survival for females compared to males for stage I-IV anal SCC. It is not clear why women have a survival advantage over men, though exposure to prominent risk factors may play a role. High-risk men may warrant routine screening for anal cancer.

ABSTRACT

BACKGROUND: Racial disparities exist in patients with rectal cancer with respect to both treatment and survival. Minority-serving hospitals (MSHs) provide healthcare to a disproportionately large percent of minority patients in the USA. We examined the effects of rectal cancer treatment at MSH to understand drivers of these disparities. METHODS: The NCDB was queried (2004-2015), and patients diagnosed with stage II or III rectal adenocarcinoma were identified. Racial case mix distribution was calculated at the institutional level, and MSHs were defined as those within the top decile of Black and Hispanic patients. Logistic regression was used to identify predictors of receipt of standard of care treatment. Survival was assessed using the Kaplan-Meier method, and Cox proportional hazards models were used to evaluate adjusted risk of death. Analyses were clustered by facility. RESULTS: A total of 68,842 patients met the inclusion criteria. Of these patients, 63,242 (91.9%) were treated at non-MSH, and 5600 (8.1%) were treated at MSH. In multivariable analysis, treatment at MSH (OR 0.70 95%CI 0.61-0.80 p < 0.001) and Black race (OR 0.75 95%CI 0.70-0.81 p < 0.001) were associated with significantly lower odds of receiving standard of care. In adjusted analysis, Black patients had a significantly higher risk of mortality (HR 1.20 95%CI 1.14-1.26 p < 0.001). CONCLUSIONS: Treatment at MSH institutions and Black race were associated with significantly decreased odds of receipt of recommended standard therapy for locally advanced rectal adenocarcinoma. Survival was worse for Black patients compared to White patients despite adjustment for receipt of standard of care.

ABSTRACT

BACKGROUND: There are various racial, socioeconomic, and tumor-specific factors that can impact rectal cancer outcomes. The current systematic review and meta-analysis evaluate the effect socioeconomic and racial variables on overall survival of rectal cancer patients after surgical resection. METHODS: A literature search was performed via electronic databases according to Systematic Reviews and Meta-Analyses and Meta-analysis Of Observational Studies in Epidemiology guidelines. All studies were evaluated by three authors and validated for data extraction. Predictive variables and survival profiles (1-, 5-, and 10-y survival and overall survival) reported by the studies were recorded for the systematic review. Hazard ratios, odds ratios, and 95% confidence intervals were extracted for meta-analysis. Forest plots were used to interpret the results. The primary outcome was the effect size of the predictive variables on overall survival after surgical resection. RESULTS: Of the 265 articles collected, 22 met inclusion criteria. Sixteen studies were used for the systematic review, and 17 studies were considered for meta-analysis. Overall, 662,053 subjects with rectal cancer were studied (439,766 with race reported), of which 344,193 (78.3%) were White and 60,283 (13.7%) were Black. The median survival was 56.8% for White patients and 47.9% for Black patients. Meta-analysis revealed that race, socioeconomic variables (education level, income level, and insurance status), and facility characteristics (type and volume) were significantly associated with overall survival in rectal cancer. CONCLUSIONS: Racial and socioeconomic disparities are present in outcomes for rectal cancer patients undergoing surgical resection. It is important to consider these disparities in the management of patients with rectal cancer to minimize any consequent disparities in surgical outcomes.

ABSTRACT

PURPOSE: Small bowel leiomyosarcoma (SB LMS) is a rare disease with few studies characterizing its outcomes. This study aims to evaluate surgical outcomes for patients with SB LMS. METHODS: The National Cancer Database was queried from 2004 to 2016 to identify patients with SB LMS who underwent surgical resection. The primary outcome was overall survival. RESULTS: A total of 288 patients with SB LMS who had undergone surgical resection were identified. The median age was 63, and the majority of patients were female (56%), White (82%), and had a Charlson comorbidity score of zero (76%). Eighty-one percent of patients had negative margins following surgical resection. Fourteen percent of patients had metastatic disease at the time of diagnosis. Nineteen percent of patients received chemotherapy and 3% of patients received radiation. One-year overall survival was 77% (95% CI: 72-82%) and 5-year overall survival was 43% (95% CI: 36-49%). Higher grade (HR: 1.98, 95% CI: 1.10-3.55, p = 0.02) and metastatic disease at diagnosis (HR: 2.57, 95% CI: 1.45-4.55, p = 0.001) were independently associated with higher risk of death. CONCLUSION: SB LMS is a rare disease entity, with treatment centering on complete surgical resection. Our results demonstrate that overall survival is higher than previously thought. Timely diagnosis to allow for complete surgical resection is key, and investigation into the possible role of chemotherapy or radiation therapy is needed.

ABSTRACT

BACKGROUND: Hemorrhoids cause more than 4 million ambulatory care visits in the United States annually, and hemorrhoidectomy is associated with significant postoperative pain. There are currently no evidence-based opioid-prescribing guidelines for hemorrhoidectomy patients. OBJECTIVE: The purpose of this study was to investigate patterns of opioid prescribing and to identify factors associated with opioid refill after hemorrhoidectomy. DESIGN: This was a retrospective database review. SETTINGS: The study was conducted using the Department of Defense Military Health System Data Repository (2006-2014). PATIENTS: Opioid-naïve patients aged 18 to 64 years enrolled in TRICARE insurance who underwent surgical hemorrhoidectomy were included in this study. MAIN OUTCOME MEASURES: We measured patterns of opioid prescriptions and predictors of a second opioid prescription within 2 weeks of the end date for the first prescription after hemorrhoidectomy. RESULTS: A total of 6294 patients were included; 5536 (88.0%) filled an initial opioid prescription with a median 5-day supply, and 1820 (32.9%) required an opioid refill. The modeled risk of refill based on initial prescription supply ranged from a high of 39.2% risk with an initial prescription of 1-day supply to an early nadir (26.1% risk of refill) with an initial 10-day supply. A variety of sociodemographic and clinical characteristics influenced the likelihood of opioid refill, including black race (OR = 0.75 (95% CI, 0.62-0.89)), history of substance abuse (OR = 3.26 (95% CI, 1.37-7.34)), and length of index opioid prescription (4-6 d, OR = 0.83 (95% CI, 0.72-0.96) or ≥7 d, OR = 0.67 (95% CI, 0.57-0.78) vs 1-3 d). LIMITATIONS: Variables assessed were limited because of the use of claims-based data. CONCLUSIONS: There is wide variability in the length of prescription opioid use after hemorrhoidectomy. Approximately one third of patients require a second prescription in the immediate postoperative period. The optimal duration appears to be between a 5- and 10-day supply. Clinicians may be able to more efficiently discharge patients with adequate analgesia while minimizing the potential for excess supply. See Video Abstract at http://links.lww.com/DCR/B112. PRESCRIPCIÓN DE MÉDICAMENTOS OPIOIDES DESPUÉS DE HEMORROIDECTOMÍA: Las afecciones hemorroidarias ocasionan anualmente más de cuatro millones de consultas ambulatorias en los Estados Unidos. La hemorroidectomía esta asociada con dolor postoperatorio muy significativo. Actualmente no existen pautas claras para la prescripción de medicamentos opioides después de hemorroidectomía, basada en la evidencia.Investigar los patrones de prescripción de medicamentos opioides e identificar los factores asociados con la acumulación de dichos opioides después de una hemorroidectomía.Revisión retrospectiva de una base de datos.Almacén de datos del Sistema de Salud militar del Departamento de Defensa de los Estados Unidos de América (2006-2014).Todos aquellos sometidos a hemorroidectomía quirúrgica, sin tratamiento opiode previo, comprendiodos entre 18-64 años y beneficiarios de seguro TRICARE.Patrones de prescripción de recetas de opioides, predictores de una segunda receta de opioides dentro las dos semanas posteriores a la fecha de finalización de la primera receta después de la hemorroidectomía.6.294 pacientes fueron incluidos en el estudio. 5.536 (88,0%) completaron una receta inicial de opioides con un suministro promedio de cinco días, y 1.820 (32,9%) pacientes requirieron reabastecerse de opioides. El riesgo modelado de reabastecimiento de opiodes basado en el suministro de la prescripción inicial, varió desde un alto riesgo (39.2%) con una prescripción inicial de suministro por día, hasta un acmé temprano (26.1% de riesgo de reabastecimiento) con un suministro inicial de 10 días. Una gran variedad de características socio-demográficas y clínicas influyeron en la probabilidad del reabastecimeinto de los opioides, incluida la raza negra (OR 0.75, intervalo de confianza (IC) del 95% (0.62, 0.89)), los antecedentes de abuso de substancias (OR 3.26, IC del 95% (1.37, 7.34)) y la duración del índice de la prescripción de opioides (4-6 días (OR 0.83, IC 95% (0.72, 0.96)), o 7 días o más (OR 0.67, IC 95% (0.57, 0,78)) comparados a 1-3 días.Las variables analizadas fueron limitadas debido al uso de datos basados en reclamos.Existe una gran variabilidad en la duración del uso de opioides recetados después de hemorroidectomía. Aproximadamente un tercio de los pacientes requieren una segunda prescripción en el postoperatorio inmediato. La duración óptima parece estar entre un suministro de cinco y 10 días. Los médicos pueden dar de alta de manera más eficiente a los pacientes con analgesia adecuada y minimizar el potencial de exceso de suministro.

ABSTRACT

BACKGROUND/OBJECTIVES: Racial disparities are known to impact cancer outcomes. The aim of this study was to assess current racial disparities in outcomes of anal squamous cell carcinoma (SCC). METHODS: The National Cancer Database was used to identify patients with anal SCC. The primary outcome was 5-year overall survival. RESULTS: There were 32 255 (88.1%) White patients and 4342 (11.9%) Black patients identified with anal SCC. Compared to White patients, Black patients were more likely to be younger, have lower median income, and be insured with Medicaid (all P < .001). The 5-year overall survival of Black and White patients for stage I disease was 71.2% and 80.6% (P < .001), for stage II disease, was 64.6% and 69.3% (P = .001), for stage III disease was 50.9% and 58.1% (P < .001), and for stage IV disease was 22.1% and 21.9% (P = .20). In a cox regression analysis, Black race was associated with significantly worse survival in stage I (HR: 1.37, 95% CI: 1.07-1.76, P = .01), stage II (HR: 1.30, 95% CI: 1.14-1.48, P < .001), and stage III disease (HR: 1.31, 95% CI: 1.16-1.47, P < .001) but not for stage IV disease (HR: 1.09, 95% CI: 0.89-1.35, P = .41). CONCLUSIONS: Black race is correlated with worse survival in patients diagnosed with anal SCC. This disparity in survival is likely multifactorial and requires further study.

ABSTRACT

BACKGROUND: Following abdominoperineal resection (APR) for rectal cancer, perineal wound complications are common. Omental flap creation may allow for decreased morbidity. The aim of this study was to assess wound complications in rectal cancer patients undergoing APR with and without the addition of an omental flap. METHODS: The National Surgical Quality Improvement Program Proctectomy targeted database from 2016 to 2017 was used to identify all patients undergoing APR for rectal cancer. The primary outcomes were wound complications such as superficial site infection, deep wound infection, organ space infection, and wound dehiscence. RESULTS: There were 3063 patients identified. One hundred seventy-three (5.6%) patients underwent APR with an omental flap repair while 2890 (94.4%) patients underwent APR without an omental flap repair. Patients in both groups were similar with regard to age, gender, body mass index, American Society of Anesthesia class, and neoadjuvant cancer treatment (all p > 0.05). Patients who underwent an omental flap repair were significantly more likely to have a postoperative organ space infection (10.4% vs. 6.5%, p = 0.04). There was no significant difference in rates of superficial site infection, deep wound infection, wound dehiscence, or reoperation between the two patient groups. In multivariable analysis, omental flap creation was independently associated with organ space infection (OR 1.72, 95%CI 1.02-2.90, p = 0.04). CONCLUSIONS: This is the largest study to evaluate omental flap use in rectal cancer patients undergoing APR. Omental flaps are independently associated with organ space infection.
