Laparoscopic versus open hepatic resection in patients ≥75 years old: A NSQIP analysis evaluating 2674 patients.

BACKGROUND: Previous studies report promising outcomes with minimally invasive (MIS) hepatectomy in elderly patients but remain limited by small size. This study aims to comparatively evaluate the demographics and outcomes of geriatric patients undergoing MIS and open hepatectomy. METHOD: The 2016-2021 NSQIP database was evaluated comparing patients ≥75 undergoing MIS versus open hepatectomy. Patient selection and outcomes were compared using bivariate analysis with multivariable modeling (MVR) evaluating factors associated with serious complications and mortality. Propensity score matched (PSM) analysis further evaluated serious complications, mortality, length of stay (LOS), Clavien Dindo Classification (CDC), and Comprehensive Complication Index (CCI) for cohorts. RESULTS: We evaluated 2674 patients with 681 (25.5%) receiving MIS hepatectomy. MIS approaches were used more for partial lobectomy (85.9% vs. 61.7%; p < 0.001), and required fewer biliary reconstructions (1.6% vs. 10.6%; p < 0.001). Patients were similar with regards to sex, body mass index, and other comorbidities. Unadjusted analysis demonstrated that MIS approaches had fewer serious complications (8.8% vs. 18.7%; p < 0.001). However, after controlling for cohort differences the MIS approach was not associated with reduced likelihood of serious complications (odds ratio [OR]: 0.77; p = 0.219) or mortality (OR: 1.19; p = 0.623). PSM analysis further supported no difference in serious complications (p = 0.403) or mortality (p = 0.446). However, following PSM a significant reduction in LOS (-1.99 days; p < 0.001), CDC (-0.26 points; p = 0.016) and CCI (-2.79 points; p = 0.022) was demonstrated with MIS approaches. CONCLUSIONS: This is the largest study comparing MIS and open hepatectomy in elderly patients. Results temper previously reported outcomes but support reduced LOS and complications with MIS approaches.

Survival benefit of neoadjuvant FOLFIRINOX for patients with borderline resectable pancreatic cancer.

Backgrounds/Aims: While patients with borderline resectable pancreatic cancer (BRPC) are a target population for neoadjuvant chemotherapy (NAC), formal guidelines for neoadjuvant therapy are lacking. We assessed the perioperative and oncological outcomes in patients with BRPC undergoing NAC with FOLFIRINOX for patients undergoing upfront surgery (US). Methods: The AHPBA criteria for borderline resectability and/or a CA19-9 level > 100 µ/mL defined borderline resectable tumors retrieved from a prospectively populated institutional registry from 2007 to 2020. The primary outcome was overall survival (OS) at 1 and 3 years. A Cox Proportional Hazard model based on intention to treat was used. A receiver-operator characteristics (ROC) curve was constructed to assess the discriminatory capability of the use of CA19-9 > 100 µ/mL to predict resectability and mortality. Results: Forty BRPC patients underwent NAC, while 46 underwent US. The median OS with NAC was 19.8 months (interquartile range [IQR], 10.3-44.24) vs. 10.6 months (IQR, 6.37-17.6) with US. At 1 year, 70% of the NAC group and 41.3% of the US group survived (p = 0.008). At 3 years, 42.5 % of the NAC group and 10.9% of the US group survived (p = 0.001). NAC significantly reduced the hazard of death (adjusted hazard ratio, 0.20; 95% confidence interval, 0.07-0.54; p = 0.001). CA19-9 > 100 µ/mL showed poor discrimination in predicting mortality, but was a moderate predictor of resectability. Conclusions: We found a survival benefit of NAC with FOLFIRINOX for BRPC. Greater pre-treatment of CA19-9 and multivessel involvement on initial imaging were associated with progression of the disease following NAC.

Tratamiento quirúrgico de las metástasis pancreáticas de cáncer renal de células claras en una institución de la Argentina / Surgical treatment of pancreatic metastases from renal clear cell carcinoma

Isolated pancreatic metastases of clear cell renal carcinoma are rare. Clear cell renal carcinoma (CCRC) is responsible for approximately 20-30 % of cases that present metastases at diagnosis. Despite that pancreatic involvement is inusual, this is an organ were particularly and frequently place as the only dissemination site. The aim of this report was to evaluate the surgical and oncological results of patients submitted to pancreatectomy consecutively to a CCRC. Patients with pancreatectomy because of metastases were selected in a 10 -year period. Clear cell renal carcinoma spreads both by direct perinephric extension and by hematogenous and lymphatic routed. The treatment of localized CCRC is surgical. For patients with metastatic CCRC, no efficacious agent has ever been identified, and there is no standard or accepted therapy. The results of this study are presented and discussed
