Pancreatic Cancer Screening among High-risk Individuals.

Pancreatic ductal adenocarcinoma (PDAC) continues to remain one of the leading causes of cancer-related death. Unlike other malignancies where universal screening is recommended, the same cannot be said for PDAC. The purpose of this study is to review which patients are at high risk of developing PDAC and therefore candidates for screening, methods/frequency of screening, and risk for these groups of patients.

National Landscape of Neoadjuvant Therapy in Potentially Resectable Colon Cancer.

INTRODUCTION: Surgery followed by pathology-guided adjuvant therapy is standard treatment for colon cancer. Data from the FOxTROT clinical trial showed potential benefit of a 6-wk neoadjuvant chemotherapy (NACT) in T3/T4 patients. The present study evaluated real-world outcomes of neoadjuvant therapy in a national cohort of patients with resectable colon cancer. METHODS: 169,120 patients with clinical stage I, II, or III colon cancer from the National Cancer Database registry were included. Patients were categorized as having received neoadjuvant therapy followed by surgery (NACT), surgery then adjuvant chemotherapy (AC), or surgery alone. Factors associated with treatment sequencing and outcomes were assessed. RESULTS: Of identified patients, 1.4% received NACT including 0.5% of stage I, 1.8% of stage II, and 3.0% of stage III. For stage I, 5-y overall survival (OS) was 74.7% after AC, 62.2% after NACT, and 76.4% after SA. For stage II, 5-y OS was 73.2% after AC, 66.8% after NACT, and 64.3% after SA. For stage III, 5-y OS was 67.3% after AC, 67.7% after NACT, and 42.4% after SA. Cox proportional-hazards model suggested NACT had worse outcomes versus AC in clinical stages I (hazard ratio [HR] = 1.59, 95% confidence interval [CI] 1.39-1.85, P < 0.01) and II (HR = 1.37, 95% CI 1.23-1.52, P < 0.01). In stage III, there was no difference in OS between NACT and AC (HR = 1.1, 95% CI 0.99-1.22, P = 0.05). CONCLUSIONS: In a real-world national cohort of patients with resectable colon cancer, NACT had no OS benefit over AC. Future studies should examine which subset of patients might benefit from neoadjuvant approaches.

A Randomized, Controlled Trial Evaluating Perioperative Risk-Stratification and Risk-Based, Protocol-Driven Management After Elective Major Cancer Surgery.

OBJECTIVE: We evaluated the efficacy of risk-based, protocol-driven management versus (vs) usual management after elective major cancer surgery to reduce 30-day rates of postoperative death or serious complications (DSC) . SUMMARY BACKGROUND DATA: Major cancer surgery is associated with significant perioperative risks which result in worse long-term outcomes. METHODS: Adults scheduled for elective major cancer surgery were stratified/randomized to risk-based escalating levels of care, monitoring, and co-management vs usual management. The primary study outcome was 30-day rate of DSC. Additional outcomes included complications, adverse events, health care utilization, health-related quality of life (HRQOL), and disease-free and overall survival (DFS and OS). RESULTS: Between August 2014 and June 2020, 1529 patients were enrolled and randomly allocated to the study arms; 738 patients in the Intervention Arm and 732 patients in the Control Arm were eligible for analysis. 30-day rate of DSC with the intervention was 15.0% (95% CI, 12.5-17.6%) vs 14.1%, (95% CI, 11.6-16.6%) with usual management (P=0.65). There were no differences in 30-day rates of complications or adverse events (including return to the operating room); postoperative length of stay; rate of discharge to home; or 30, 60, or 90-day HRQOL or rates of hospital readmission or receipt of anti-neoplastic therapy between the study arms. At median follow-up of 48 months, OS (P=0.57) and DFS (P=0.91) were similar. CONCLUSIONS: Risk-based, protocol-driven management did not reduce 30-day rate of DSC after elective major cancer surgery compared to usual management, nor improve postoperative health care utilization, HRQOL, or cancer outcomes. Trials are needed to identify cost-effective, tailored perioperative strategies to optimize outcomes after major cancer surgery.

Percutaneous Drainage of Pediatric Pulmonary Abscesses: An Effective Therapy.

INTRODUCTION: Pulmonary abscess is a complication of lung infection with localized necrosis and purulent cavity formation. Pulmonary abscesses are typically managed using antibiotic therapy with anatomic surgical resection reserved as a rescue. Percutaneous drainage is considered relatively contraindicated in some centers due to perceived risk of bronchopleural fistula. However, drain placement has been frequently employed at our institution. The purpose of this study was to review and describe our longitudinal experience. METHODS: Medical records of children diagnosed with lung abscess and treated with percutaneous drainage from 2005 through 2023 were reviewed. Patient clinical parameters, follow-up imaging, and clinical outcomes were evaluated. RESULTS: Percutaneous drainage (n = 24) or aspiration alone (n = 4) under imaging guidance was performed by interventional radiologists for 28 children with lung abscesses. A single catheter (8-12 Fr) was deployed in the pulmonary abscess cavity and remained for a median of 6 days (IQR: 6-8 days). The median hospital stay was 10 days (IQR: 8.8-14.8 days). The technical success rate for percutaneous drainage or aspiration of primary pulmonary abscesses was 100% (26/26). Two children were later diagnosed with secondarily infected congenital pulmonary airway malformations that were both successfully drained and ultimately surgically resected. The abscess cavities resolved in all patients and catheters were removed upon clinical, radiographic, and laboratory improvement. Complications included the presence of two bronchopleural fistula, both of which were treated with immediate pleural drain placement. CONCLUSION: Percutaneous drainage of pulmonary abscesses is an effective therapeutic option in children and can be considered alongside antibiotics as part of the initial treatment for pulmonary abscesses. Bronchopleural fistula can occur, but at a lower frequency than previously reported. LEVEL OF EVIDENCE: Level V.

Sphingosine is involved in PAPTP-induced death of pancreas cancer cells by interfering with mitochondrial functions.

Pancreas ductal adenocarcinoma belongs to the most common cancers, but also to the tumors with the poorest prognosis. Here, we pharmacologically targeted a mitochondrial potassium channel, namely mitochondrial Kv1.3, and investigated the role of sphingolipids and mutated Kirsten Rat Sarcoma Virus (KRAS) in Kv1.3-mediated cell death. We demonstrate that inhibition of Kv1.3 using the Kv1.3-inhibitor PAPTP results in an increase of sphingosine and superoxide in membranes and/or membranes associated with mitochondria, which is enhanced by KRAS mutation. The effect of PAPTP on sphingosine and mitochondrial superoxide formation as well as cell death is prevented by sh-RNA-mediated downregulation of Kv1.3. Induction of sphingosine in human pancreas cancer cells by PAPTP is mediated by activation of sphingosine-1-phosphate phosphatase and prevented by an inhibitor of sphingosine-1-phosphate phosphatase. A rapid depolarization of isolated mitochondria is triggered by binding of sphingosine to cardiolipin, which is neutralized by addition of exogenous cardiolipin. The significance of these findings is indicated by treatment of mutated KRAS-harboring metastasized pancreas cancer with PAPTP in combination with ABC294640, a blocker of sphingosine kinases. This treatment results in increased formation of sphingosine and death of pancreas cancer cells in vitro and, most importantly, prolongs in vivo survival of mice challenged with metastatic pancreas cancer. KEY MESSAGES: Pancreatic ductal adenocarcinoma (PDAC) is a common tumor with poor prognosis. The mitochondrial Kv1.3 ion channel blocker induced mitochondrial sphingosine. Sphingosine binds to cardiolipin thereby mediating mitochondrial depolarization. Sphingosine is formed by a PAPTP-mediated activation of S1P-Phosphatase. Inhibition of sphingosine-consumption amplifies PAPTP effects on PDAC in vivo.

Chimeric versus Multiple Flaps for Composite Oral Cavity Defects: A Systematic Review and Meta-Analysis.

OBJECTIVES: Complex head and neck defects involving composite defects can be reconstructed using chimeric flaps or multiple flaps with separate anastomoses. Limited comparisons exist between chimeric and multiple flap reconstructions. We compare outcomes between chimeric and multiple flap reconstructions in oral cavity reconstruction. DATA SOURCES: PubMed (NLM), Embase (Elsevier), Web of Science (Clarivate Analytics), and Cochrane CENTRAL (Wiley). METHODS: A systematic review was conducted, including English articles reporting outcomes of oral cavity reconstruction with either chimeric flaps or multiple flaps. Data extraction included patient characteristics, flap type, and outcomes such as flap survival, partial flap loss, operating room time, hospital length of stay, and postoperative complications. RESULTS: Forty-seven articles comprising 1435 patients were included. Notably, 552 patients underwent multiple flaps, while 883 received chimeric flaps. Meta-analysis revealed no statistically significant difference in flap survival between chimeric and multiple flap patients (98% vs. 99%, p = 0.198). Multiple flap patients had higher rates of operating room take-backs for anastomotic issues and longer hospital stays compared with chimeric flap patients. There were no significant differences in partial flap failure, resumption of diet and speech, need for subsequent flaps, fistula formation, or general complications. CONCLUSION: This large-scale meta-analysis demonstrates equivalent flap survival between chimeric and multiple flaps in the reconstruction of composite oral cavity defects. Both approaches appear to be safe and acceptable, with comparable outcomes in terms of diet and speech resumption, rates of fistulization, and general postoperative complications. Multiple flap patients had higher rates of operating room take-backs and longer hospital stays. LEVEL OF EVIDENCE: NA Laryngoscope, 134:4196-4202, 2024.

Preoperative CA 19-9 Predicts Disease Progression in Colorectal Peritoneal Metastases Treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: An Analysis from the US HIPEC Collaborative.

INTRODUCTION: Patients with colorectal peritoneal metastases (CRPM) are increasingly treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Unfortunately, data identifying preoperative risk factors for poor oncologic outcomes after this procedure are limited. We aimed to determine the prognostic value of preoperative CEA, CA 125, and CA 19-9 on disease progression after CRS/HIPEC. METHODS: Patients with CRPM treated with curative intent CRS/HIPEC from 12 participating sites in the United States from 2000 to 2017 were identified. Progression-free survival (PFS), defined as disease progression or recurrence, was the primary outcome. RESULTS: In 279 patients who met inclusion criteria, the rate of disease progression was 63.8%, with a median PFS of 11 months (interquartile range [IQR] 5-20). Elevated CA 19-9 was associated with dismal PFS at 2 years (8.9% elevated vs. 30% not elevated, p < 0.01). In 113 patients who underwent upfront CRS/HIPEC, CA 19-9 emerged as the sole tumor marker independently predictive of worse PFS (hazard ratio [HR] 2.88, p = 0.048). In the subgroup of patients who had received neoadjuvant therapy (NAT), no variable was independently predictive of PFS. CA 19-9 levels over 37 U/ml were highly specific for accelerated disease progression after CRS/HIPEC. Lastly, there was no association between PFS and elevated CEA or CA 125. CONCLUSIONS: Elevated CA 19-9 is associated with decreased PFS in patients with CRPM. While traditionally CEA is the main tumor marker assessed in colon cancer, we found that CA 19-9 may better inform preoperative risk stratification for poor oncologic outcomes in patients with CRPM. However, prospective studies are required to confirm this association.

Contemporary Prophylactic Antibiotic Practices and Adjunct Therapies in Autologous Fat Grafting Procedures: A Survey of The Aesthetic Society Members.

Background: Autologous fat grafting (AFG) is a widely used surgical technique that involves extracting a patient's own adipose tissue and transferring it to different areas of the body. This practice is still evolving. Guidelines for antibiotic prophylaxis and use of adjuncts in plastic surgery are currently limited, with a notable absence of standardized guidelines for AFG. Objectives: In this survey, we assess contemporary antibiotic practices and adjuncts in AFG procedures. Methods: A 52-question survey was emailed to 3106 active members of The Aesthetic Society. Two hundred and ninety-three responses were recorded, representing a 9% response rate. Results: We analyzed 288 responses. The most common AFG procedures were facial (38%), gluteal (34%), and breast (27%) augmentation. Preoperative antibiotics were used by 84.0% overall, with rates of 74.3%, 88.0%, and 92.7% in face, breast, and gluteal AFG, respectively. Lipoaspirate-antibiotic mixing was reported by 19.8%, mainly during gluteal AFG (46.9%), and less so in face (2.8%) and breast (8%) AFG. Notably, 46.9% of surgeons administered prolonged prophylaxis for 72 h or more. Tranexamic acid was utilized by 39.9% of the surveyed surgeons. Platelet-rich plasma was used by 5.6%. Doppler ultrasound was incorporated by 16.7% in AFG, with 21.5% in gluteal AFG, 14% in the face, and 19% in breast procedures. Conclusions: In this survey, we offer insights into antibiotic practices and adjunct therapies in AFG, especially intraoperative antibiotic mixing. Practices among members of The Aesthetic Society vary from guidelines. It is crucial to standardize practices and conduct further research to pave the way for evidence-based guidelines in AFG.

Bard Versus the 2022 American Society of Plastic Surgeons In-Service Examination: Performance on the Examination in Its Intern Year.

Background: Bard is a conversational generative artificial intelligence (AI) platform released by Google (Mountain View, CA) to the public in May 2023. Objectives: This study investigates the performance of Bard on the American Society of Plastic Surgeons (ASPS) In-Service Examination to compare it to residents' performance nationally. We hypothesized that Bard would perform best on the comprehensive and core surgical principles portions of the examination. Methods: Google's 2023 Bard was used to answer questions from the 2022 ASPS In-Service Examination. Each question was asked as written with the stem and multiple-choice options. The 2022 ASPS Norm Table was utilized to compare Bard's performance to that of subgroups of plastic surgery residents. Results: A total of 231 questions were included. Bard answered 143 questions correctly corresponding to an accuracy of 62%. The highest-performing section was the comprehensive portion (73%). When compared with integrated residents nationally, Bard scored in the 74th percentile for post-graduate year (PGY)-1, 34th percentile for PGY-2, 20th percentile for PGY-3, 8th percentile for PGY-4, 1st percentile for PGY-5, and 2nd percentile for PGY-6. Conclusions: Bard outperformed more than half of the first-year integrated residents (74th percentile). Its best sections were the comprehensive and core surgical principle portions of the examination. Further analysis of the chatbot's incorrect questions might help improve the overall quality of the examination's questions.

Defining the operative time threshold for safety in patients undergoing robotic pancreaticoduodenectomy.

BACKGROUND: Robotic pancreaticoduodenectomy (RPD) is a safe and efficacious procedure in appropriately selected patients, though frequently with increased operative times compared to open pancreaticoduodenectomy (OPD). METHODS: From 2014 to 2019, patients who underwent elective, low-risk, RPDs and OPDs in the NSQIP database were isolated. The operative time threshold (OTT) for safety in RPD patients was estimated by identifying the operative time at which complication rates for RPD patients exceeded the complication rate of the benchmark OPD control. RESULTS: Of 6270 patients identified, 939 (15%) underwent RPD and 5331 (85%) underwent OPD. The incidence of major morbidity or mortality for the OPD cohort was 35.1%. The OTT was identified as 7.7 h. Patients whose RPDs were above the OTT experienced a higher incidence of major morbidity (42.5% vs. 35.0%, p < 0.01) and 30-day mortality (2.7% vs. 1.2%, p = 0.03) than the OPD cohort. Preoperative obstructive jaundice (OR: 1.47, [95% CI: 1.08-2.01]) and pancreatic duct size <3 mm (OR: 2.44, [95% CI: 1.47-4.06]) and 3-6 mm (OR: 2.15, [95% CI: 1.31-3.52]) were risk factors for prolonged RPDs on multivariable regression. CONCLUSION: The operative time threshold for safety, identified at 7.7 h, should be used to improve patient selection for RPDs and as a competency-based quality benchmark.

ASO Practice Guidelines Series: Management of Resectable, Borderline Resectable, and Locally Advanced Pancreas Cancer.

Pancreatic adenocarcinoma is an aggressive disease marked by high rates of both local and distant failure. In the minority of patients with potentially resectable disease, multimodal treatment paradigms have allowed for prolonged survival in an increasingly larger pool of well-selected patients. Therefore, it is critical for surgical oncologists to be abreast of current guideline recommendations for both surgical management and multimodal therapy for pancreas cancer. We discuss these guidelines, as well as the underlying data supporting these positions, to offer surgical oncologists a framework for managing patients with pancreatic adenocarcinoma.

Post-Exposure Prophylaxis for Varicella-Zoster Virus Exposure in High-Risk Children.

BACKGROUND: Post-exposure prophylaxis (PEP) with varicella immunoglobulin is recommended to minimize risk of varicella complications for high-risk children. However, providers frequently use alternatives like acyclovir or intravenous immunoglobulin. METHODS: A retrospective cohort study was conducted of PEP for varicella in children from January 2009 to December 2019. Data were provided by 47 children's hospitals who participate in the Pediatric Health Information Systems database. Patients with clinical encounters for varicella exposure were reviewed. Choice of varicella PEP regimens, including differences by underlying condition and institution, and incidence of varicella disease were determined. RESULTS: A total of 1704 patients with first clinical encounters for varicella met inclusion criteria. Of these patients, 509 (29.9%) were prescribed PEP after varicella exposure, and 65 (3.8%) ultimately had a subsequent encounter for varicella disease. Of 509 patients who received PEP, acyclovir was most frequently prescribed (n = 195, 38.3%), followed by varicella immunoglobulin (n = 146, 28.7%), IVIG (n = 115, 22.6%), and combination therapy (n = 53, 10.4%). The highest proportion of varicella immunoglobulin use (10/20, 50%) was amongst children with diagnoses of rheumatological/gastrointestinal conditions. The highest proportion of acyclovir use (29/684, 4.2%) was amongst children with diagnoses of oncology/stem cell transplant conditions. The proportion of patients who subsequently had clinical encounters for varicella disease was highest for Acyclovir (30/195, 15.4%) followed by varicella immunoglobulin (5/146, 3.4%), combination therapy (2/53, 3.8%), and intravenous immunoglobulin alone (0/115) (P < .0001). CONCLUSIONS: Varicella PEP in high-risk children was highly varied among children's hospitals. In our dataset, use of acyclovir was associated with a higher rate of subsequent encounters for Varicella disease.

Transition to Value-based Healthcare: Development, Implementation, and Results of an Optimal Surgical Care Framework at a National Cancer Institute-designated Comprehensive Cancer Center.

BACKGROUND: The continued rise in healthcare expenditures has not produced commensurate improvements in patient outcomes, leading US healthcare stakeholders to emphasize value-based care. Transition to such a model requires all team members to adopt a new strategic and organizational framework. OBJECTIVE: To describe and report a strategy for the implementation of a novel patient-centered value-based "optimal surgical care" (OSC) framework, with validation and cost analysis in kidney surgery. DESIGN, SETTING, AND PARTICIPANTS: An observational study of care episodes at a single institution from 2014 to 2019 was conducted. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multidisciplinary teams defined OSC by core and procedure-specific metrics using a combination of provider-based ("bottom-up") and "clinical leadership"-based ("top-down") strategies. Baseline OSC rates across were established, while identifying proportions of OSC achieved by coefficient of variation (CV) in total direct costs. Multivariable linear regression comparing cost between OSC and non-OSC encounters was performed, adjusting for patient characteristics. RESULTS AND LIMITATIONS: An analysis of 30 261 perioperative care episodes was performed. Following the implementation of an OSC framework, there was an increase in OSC rates across all procedure buckets using core (25%) and procedure-specific (26%) metrics. Among the tumors tested, kidney cancer surgical episodes held the highest OSC rate improvement (67%) with lowest variability in cost (CV 0.5). OSC was associated with significant total cost savings across all tumor types after adjusting for inflation (p < 0.05). Compared with non-OSC episodes, a significant reduction in the cost ratio of OSC was noted for renal surgery (p < 0.01), with estimated costs savings of $2445.87 per OSC encounter. CONCLUSIONS: Institutional change directing efforts toward optimizing surgical care and emphasizing value rather than focusing solely on expense reduction is associated with improved outcomes, while potentially reducing costs. The strategy for implementation requires serial performance analyses, engaging and educating providers, and continuous ongoing adjustments to achieve durable results. PATIENT SUMMARY: In this study, we report our strategy and outcomes for transitioning to a value-based healthcare model using a novel "optimal surgical care" framework at a National Cancer Institute-designated comprehensive cancer center. We observed an increase in optimal surgical care episodes across all specialties after 5 yr, with a potential associated reduction in cost expenditure. We conclude that the key to a successful and sustained transition is the implementation strategy, focusing on continual review and provider engagement.

Survey of Surgeon-reported Postoperative Protocols for Deep Inferior Epigastric Perforator Flap in Breast Reconstruction.

Background: The use of deep inferior epigastric perforator (DIEP) flaps is a well-established breast reconstruction technique. Methods: A 29-question survey was e-mailed to 3186 active American Society of Plastic Surgeons members, aiming to describe postoperative monitoring practice patterns among surgeons performing DIEP flaps. Results: From 255 responses (8%), 79% performing DIEP surgery were analyzed. Among them, 34.8% practiced for more than 20 years, 34.3% for 10-20 years, and 30.9% for less than 10 years. Initial 24-hour post-DIEP monitoring: intensive care unit (39%) and floor (36%). Flap monitoring: external Doppler (71%), tissue oximetry (41%), and implantable Doppler (32%). Postoperative analgesia: acetaminophen (74%), non-steroidal anti-inflammatory drugs (69%), neuromodulators (52%), and opioids (4.4%) were administered on a scheduled basis. On postoperative day 1, 61% halt intravenous fluids, 67% allow ambulation, 70% remove Foley catheter, and 71% start diet. Most surgeons discharged patients from the hospital on postoperative day 3+. Regardless of experience, patients were commonly discharged on day 3. Half of the surgeons are in academic/nonacademic settings and discharge on/after day 3. Conclusions: This study reveals significant heterogeneity among the practice patterns of DIEP surgeons. In light of these findings, it is recommended that a task force be convened to establish standardized monitoring protocols for DIEP flaps. Such protocols have the potential to reduce both the length of hospital stays and overall care costs all while ensuring optimal pain management and vigilant flap monitoring.

Prediction of Early Recurrence Following CRS/HIPEC in Patients With Disseminated Appendiceal Cancer.

INTRODUCTION: In patients with disseminated appendiceal cancer (dAC) who underwent cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC), characterizing and predicting those who will develop early recurrence could provide a framework for personalizing follow-up. This study aims to: (1) characterize patients with dAC that are at risk for recurrence within 2 y following of CRS ± HIPEC (early recurrence; ER), (2) utilize automated machine learning (AutoML) to predict at-risk patients, and (3) identifying factors that are influential for prediction. METHODS: A 12-institution cohort of patients with dAC treated with CRS ± HIPEC between 2000 and 2017 was used to train predictive models using H2O.ai's AutoML. Patients with early recurrence (ER) were compared to those who did not have recurrence or presented with recurrence after 2 y (control; C). However, 75% of the data was used for training and 25% for validation, and models were 5-fold cross-validated. RESULTS: A total of 949 patients were included, with 337 ER patients (35.5%). Patients with ER had higher markers of inflammation, worse disease burden with poor response, and received greater intraoperative fluids/blood products. The highest performing AutoML model was a Stacked Ensemble (area under the curve = 0.78, area under the curve precision recall = 0.66, positive predictive value = 85%, and negative predictive value = 63%). Prediction was influenced by blood markers, operative course, and factors associated with worse disease burden. CONCLUSIONS: In this multi-institutional cohort of dAC patients that underwent CRS ± HIPEC, AutoML performed well in predicting patients with ER. Variables suggestive of poor tumor biology were the most influential for prediction. Our work provides a framework for identifying patients with ER that might benefit from shorter interval surveillance early after surgery.

Feeding Jejunostomy Tube in Patients Undergoing Esophagectomy: Utilization and Outcomes in a Nationwide Cohort.

BACKGROUND: Feeding jejunostomy (JT) tubes are often utilized as an adjunct to optimize nutrition for successful esophagectomy; however, their utility has come into question. The aim of this study was to evaluate utilization and outcomes associated with JTs in a nationwide cohort of patients undergoing esophagectomy. METHODS: The NSQIP database was queried for patients who underwent elective esophagectomy. JT utilization was assessed between 2010 and 2019. Post-operative outcomes were compared between those with and without a JT on patients with esophagectomy-specific outcomes (2016-2019), with results validated using a propensity score-matched (PSM) analysis based on key clinicopathologic factors, including tumor stage. RESULTS: Of the 10,117 patients who underwent elective esophagectomy over the past decade, 53.0% had a JT placed concurrently and 47.0% did not. Utilization of JTs decreased over time, accounting for 60.0% of cases in 2010 compared to 41.7% in 2019 (m = - 2.14 95%CI: [- 1.49]-[- 2.80], p < 0.01). Patients who underwent JT had more composite wound complications (17.0% vs. 14.1%, p = 0.02) and a higher rate of all-cause morbidity (40.4% vs. 35.5%, p = 0.01). Following PSM, 1007 pairs were identified. Analysis of perioperative outcomes demonstrated a higher rate of superficial skin infections (6.1% vs. 3.5%, p = 0.01) in the JT group. However, length of stay, reoperation, readmission, anastomotic leak, composite wound complications, all-cause morbidity, and mortality rates were similar between groups. CONCLUSIONS: Among patients undergoing elective esophagectomy, feeding jejunostomy tubes were utilized less frequently over the past decade. Similar perioperative outcomes among matched patients support the safety of esophagectomy without an adjunct feeding jejunostomy tube.

Cancer screening and management in the transgender population: Review of literature and special considerations for gender affirmation surgery.

BACKGROUND: Literature focused on cancer screening and management is lacking in the transgender population. AIM: To action to increase contributions to the scientific literature that drives the creation of cancer screening and management protocols for transgender and gender nonconforming (TGNC) patients. METHODS: We performed a systematic search of PubMed on January 5th, 2022, with the following terms: "TGNC", OR "transgender", OR "gender non-conforming", OR "gender nonbinary" AND "cancer screening", AND "breast cancer", AND "cervical cancer", AND "uterine cancer", AND "ovarian cancer", AND "prostate cancer", AND "testicular cancer", AND "surveillance", AND "follow-up", AND "management". 70 unique publications were used. The findings are discussed under "Screening" and "Management" categories. RESULTS: Screening: Current cancer screening recommendations default to cis-gender protocols. However, long-term gender-affirming hormone therapy and loss to follow-up from the gender-specific specialties contribute to a higher risk for cancer development and possible delayed detection. The only known screening guidelines made specifically for this population are from the American College of Radiology for breast cancer. Management: Prior to undergoing Gender Affirmation Surgery (GAS), discussion should address cancer screening and management in the organs remaining in situ. Cancer treatment in this population requires consideration for chemotherapy, radiation, surgery and/or reconstruction. Modification of hormone therapy is decided on a case-by-case basis. The use of prophylactic vs aesthetic techniques in surgery is still debated. CONCLUSION: When assessing transgender individuals for GAS, a discussion on the future oncologic risk of the sex-specific organs remaining in situ is essential. Cancer management in this population requires a multidisciplinary approach while the care should be highly individualized with considerations to social, medical, surgical and gender affirming surgery related specifications. Special considerations have to be made during planning for GAS as surgery will alter the anatomy and may render the organ difficult to sample for screening purposes. A discussion with the patient regarding the oncologic risk of remaining organs is imperative prior to GAS. Other special considerations to screening such as the conscious or unconscious will to unassociated with their remaining organs is also a key point to address. We currently lack high quality studies pertinent to the cancer topic in the gender affirmation literature. Further research is required to ensure more comprehensive and individualized care for this population.

Neighborhood-Level Socioeconomic Disadvantage Predicts Outcomes in Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Malignancy.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) improves survival in select patients with peritoneal metastases (PM), but the impact of social determinants of health on CRS/HIPEC outcomes remains unclear. PATIENTS AND METHODS: A retrospective review was conducted of a multi-institutional database of patients with PM who underwent CRS/HIPEC in the USA between 2000 and 2017. The area deprivation index (ADI) was linked to the patient's residential address. Patients were categorized as living in low (1-49) or high (50-100) ADI residences, with increasing scores indicating higher socioeconomic disadvantage. The primary outcome was overall survival (OS). Secondary outcomes included perioperative complications, hospital/intensive care unit (ICU) length of stay (LOS), and disease-free survival (DFS). RESULTS: Among 1675 patients 1061 (63.3%) resided in low ADI areas and 614 (36.7%) high ADI areas. Appendiceal tumors (n = 1102, 65.8%) and colon cancer (n = 322, 19.2%) were the most common histologies. On multivariate analysis, high ADI was not associated with increased perioperative complications, hospital/ICU LOS, or DFS. High ADI was associated with worse OS (median not reached versus 49 months; 5 year OS 61.0% versus 28.2%, P < 0.0001). On multivariate Cox-regression analysis, high ADI (HR, 2.26; 95% CI 1.13-4.50; P < 0.001), cancer recurrence (HR, 2.26; 95% CI 1.61-3.20; P < 0.0001), increases in peritoneal carcinomatosis index (HR, 1.03; 95% CI 1.01-1.05; P < 0.001), and incomplete cytoreduction (HR, 4.48; 95% CI 3.01-6.53; P < 0.0001) were associated with worse OS. CONCLUSIONS: Even after controlling for cancer-specific variables, adverse outcomes persisted in association with neighborhood-level socioeconomic disadvantage. The individual and structural-level factors leading to these cancer disparities warrant further investigation to improve outcomes for all patients with peritoneal malignancies.
