Background The objective of the current study was to investigate both short-and long-term outcomes of patients undergoing curative-intent resection for intrahepatic cholangiocarcinoma (ICC) stratified by extent of hepatic resection relative to overall final pathological margin status. Methods One thousand twenty-three patients with ICC who underwent curative-intent resection were identified from a multiinstitutional database. Demographic, clinicopathological, and operative data, as well as overall (OS) and recurrence-free survival (RFS) were compared among patients undergoing major and minor resection before and after propensity score matching. Results Overall, 608 (59.4%) patients underwent major hepatectomy, while 415 (40.6%) had a minor resection. Major hepatectomy was more frequently performed among patients who had large, multiple, and bilobar tumors. Roughly half of patients (n = 294, 48.4%) developed a postoperative complication following major hepatectomy versus only one fourth of patients (n = 113, 27.2%) after minor resection (p < 0.001). In the propensity model, patients who underwent major hepatectomy had an equivalent OS and RFS versus patients who had a minor hepatectomy (median OS, 38 vs. 37 months, p = 0.556; and median RFS, 20 vs. 18 months, p = 0.635). Patients undergoing major resection had comparable OS and RFS with wide surgical margin (≥10 and 5-9 mm), but Electronic supplementary material The online version of this article

Imaging-based TBS was superior to traditional tumor size and number and was comparable to pathology-based TBS. Imaging-based TBS may have the potential to facilitate improved preoperative risk stratification of patients with CRLM.

Additional resection of a positive frozen-section ductal margin to achieve R0 resection was associated with improved long-term outcomes following curative-intent resection of HCCA.

Background Early tumor recurrence after curative resection typically indicates a poor prognosis. The objective of the current study was to investigate the risk factors, treatment, and prognosis of early recurrence of neuroendocrine tumor (NET) liver metastasis (NELM) after hepatic resection. Methods A total of 481 patients who underwent curative-intent resection for NELM were identified from a multiinstitutional database. Data on clinicopathological characteristics, intraoperative details, and outcomes were documented. The optimal cutoff value to differentiate early and late recurrence was determined to be 3 years based on linear regression. Results With a median follow-up of 60 months, 223 (46.4%) patients developed a recurrence, including 158 (70.9%) early and 65 (29.1%) late recurrences. On multivariable analysis, pancreatic NET, primary tumor lymph node metastasis, and a microscopic positive surgical margin were independent risk factors for early intrahepatic recurrence. While recurrence patterns and treatments were comparable among patients with early and late recurrences, early recurrence was associated with worse diseasespecific survival than late recurrences (10-year NELM-specific survival, 44.5 vs 75.8%, p < 0.001). Among the 34 (21.5%) patients who underwent curative treatment for early recurrence, post-recurrence disease-specific survival was better than noncuratively treated patients (10-year NELM-specific survival, 54.2 vs 26.3%, p = 0.028), yet similar to patients with late recurrences treated with curative intent (10-year NELM-specific survival, 54.2 vs 37.4%, p = 0.519). Conclusions Early recurrence after surgery for NELM was associated with the pancreatic type, primary lymph node metastasis, and extrahepatic disease. Re-treatment with curative intent prolonged survival after recurrence, and therefore, operative intervention even for early recurrences of NELM should be considered.

The median decrease in total bilirubin levels after biliary drainage was similar comparing PTBD (n = 104) versus EBD (n = 92) (mg/dL, 4.9 vs 4.9, P = 0.589) before surgery. There was no difference in baseline demographic characteristics, type of surgical procedure performed, final AJCC tumor stage or postoperative morbidity among patients who underwent EBD only versus PTBD (all P > 0.05). Patients who underwent PTBD versus EBD had a comparable long-term DSS (median, 43.7 vs 36.9 months, P = 0.802) and RFS (median, 26.7 vs 24.0 months, P = 0.571). The overall pattern of recurrence relative to regional or distant disease was also the same among patients undergoing PTBD and EBD (P = 0.669) CONCLUSIONS: Oncologic outcomes including DSS and RFS were similar among patients who underwent PTBD versus EBD with no difference in tumor recurrence location.
