RESUMO
BACKGROUND: The prognostic impact of genetic mutations for patients who undergo cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) of colorectal origin (CRC) is not well defined. OBJECTIVE: We aimed to describe the genetic classifications in an unsupervised fashion, and the outcomes of this patient population. METHODS: A retrospective, bi-institutional study was performed on patients who underwent CRS-HIPEC with targeted mutation data with a median follow-up time of 61 months. Functional link analysis was performed using STRING v11.5. Genes with similar functional significance were clustered using unsupervised k-means clustering. Chi-square, Kaplan-Meier, and the log-rank test were used for comparative statistics. RESULTS: Sixty-four patients with peritoneal carcinomatosis from CRC origin underwent CRS-HIPEC between 2007 and 2022 and genetic mutation data were extracted. We identified 19 unique altered genes, with KRAS (56%), TP53 (33%), and APC (22%) being the most commonly altered; 12.5% had co-altered KRAS/TP53. After creating an interactome map, k-means clustering revealed three functional clusters. Reactome Pathway analysis on three clusters showed unique pathways (1): Ras/FGFR3 signaling; (2) p53 signaling; and (3): NOTCH signaling. Seventy-one percent of patients in cluster 1 had KRAS mutations and a median overall survival of 52.3 months (p < 0.05). CONCLUSIONS: Patients with peritoneal carcinomatosis (PC) of CRC origin who underwent CRS-HIPEC and with tumors that harbored mutations in cluster 1 (Ras/FGFR3 signaling) had worse outcomes. Pathway disruption and a cluster-centric perspective may affect prognosis more than individual genetic alterations in patients with PC of CRC origin.

Synovial sarcoma is a rare soft tissue sarcoma which frequently involves the upper or lower extremities. Soft tissue sarcomas including synovial sarcoma have a propensity to metastasize to the lungs, and there are very few reports of metastatic lesions in other locations.Here, we report a case of a 49-year-old patient who underwent neoadjuvant chemoradiation for an upper extremity synovial sarcoma and presented approximately 4 years later with abdominal pain and hemoperitoneum and was ultimately found to have metastatic synovial sarcoma involving the greater curvature of the stomach and surrounding peri-gastric soft tissue. We describe the multidisciplinary management of this complex patient presentation and propose that expanded surveillance imaging beyond that of the local tumor resection bed and the chest may be beneficial especially in tumors with high-risk features.

BACKGROUND: Gallbladder cancer accounts for 1.2% of global cancer diagnoses. Literature on biliary-type adenocarcinoma (BTA), and specifically carcinoma arising from intracholecystic papillary-tubular neoplasms (ICPNs), is limited. This study describes a retrospective, single-institution experience with gallbladder cancer, focusing on histological subtypes and prognosis. METHODS: A retrospective review was performed of patients who underwent cholecystectomy for a malignant neoplasm of the gallbladder between 2007 and 2017. Demographic, clinicopathologic, and operative variables, as well as survival outcomes, were analyzed. RESULTS: From a total of 145 patients, BTAs were most common (93, 64%). Compared with non-BTAs, BTAs were diagnosed at a lower American Joint Committee on Cancer stage (p = 0.045) and demonstrated longer median recurrence-free survival (38 vs. 16 months, p = 0.014; median follow-up 36 months). Tumors arising from ICPNs (18, 12%) were more commonly associated with BTA (14 cases). Compared with BTAs not associated with ICPNs (29 patients), associated cases demonstrated lower pathologic stage (p = 0.006) and lower rates of liver and perineural invasion (0% vs. 49% and 14% vs. 48%, respectively; p < 0.05). Cumulative 5-year survival probability was higher for patients with gallbladder neoplasm of any subtype associated with ICPNs compared with those that were not associated with ICPNs (54% vs. 41%, p = 0.019; median follow-up 23 months). This difference was also significant when comparing BTAs associated with ICPNs and non-associated cases (63% vs. 52%, p = 0.005). CONCLUSIONS: This study demonstrated unique pathological and prognostic features of BTAs and of carcinomas arising from ICPNs. Histopathological variance may implicate prognosis and may be used to better guide clinical decision making in the treatment of these patients.

INTRODUCTION: Hypophosphatemia following surgery is associated with a higher rate of postoperative complications; however, the significance of postoperative hypophosphatemia after cytoreductive surgery and heated intraperitoneal chemotherapy (CRS/HIPEC) is unknown. METHODS: A prospectively maintained database was queried for all patients who underwent CRS/HIPEC for any histology at the Mount Sinai Health System. The perioperative serum phosphate levels, postoperative complications, and comorbidities were compared between patients with or without major complications. RESULTS: From 2007 to 2018, 327 patients underwent CRS/HIPEC. Most of the patients had low phosphate levels on postoperative day (POD) 2, reaching a median nadir of 2.3 mg/dL on POD 3. Patients with major complications had significantly lower levels of serum phosphate on POD 5-7 compared with patients without complications, with median serum phosphate 2.2 mg/dL (IQR 1.9-2.4) versus 2.7 mg/dL, (IQR 2.3-3), P < 0.01. Hypophosphatemia on POD 5-7 was also more frequent in patients who developed an anastomotic leak, with median serum phosphate 2.2 mg/dL (IQR 1.9-2.6) versus 2.8 mg/dL (IQR 2.2-3.2), P = 0.001. On multivariate analysis, the number of organs resected at surgery, diaphragm resection, postoperative intensive care unit stay, and serum phosphate level <2.4 mg/dL on POD 5-7 were independently associated with a major complication after CRS/HIPEC. CONCLUSIONS: Following CRS/HIPEC, POD 5-7 hypophosphatemia is associated with severe postoperative complications and anastomotic leak.

INTRODUCTION: The role of laparoscopy in cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is not well established. Herein, we describe our early experience of laparoscopic CRS/HIPEC in patients with low-volume peritoneal disease compared to patients who underwent open CRS/HIPEC during the same time period. METHODS: Using a prospectively maintained database, patients who underwent laparoscopic CRS/HIPEC were compared to a control cohort of patients who underwent open CRS/HIPEC, matched for peritoneal carcinomatosis index (PCI), completeness of cytoreduction, and tumor histology. RESULTS: Between 2008 and 2017, 16 patients underwent laparoscopic CRS/HIPEC and were compared to a matched control cohort of 32 patients who underwent open CRS/HIPEC. Clinical and demographic data were similar between the groups. PCI, number of resected organs, and optimal cytoreduction rates were comparable. Patients who underwent laparoscopic experienced a lower estimated blood loss, (median, [IQR 1-3]); 150 mL, [50-300] vs. 100 mL, [50-125], p = 0.04, shorter length of stay (median [IQR 1-3]; 4 days [3-6] vs. 6 days [5-8], p < 0.01, and a lower 30-day complication rate (6.3% vs. 56.3%, p < 0.01). There was no difference in progression-free survival (p = 0.577) and overall survival (p = 0.472) between the groups. CONCLUSIONS: This preliminary study demonstrates that laparoscopic CRS/HIPEC is feasible and safe for curative treatment in selected patients with low tumor volume. Minimally invasive CRS/HIPEC is associated with fewer postoperative complications and shorter length of stay. There was no difference in long-term oncological outcomes between the groups.

BACKGROUND: In the United States, mortality after a diagnosis of hepatocellular carcinoma (HCC) is higher in patients who are Black than in patients of other racial groups. The objective of this study was to clarify factors contributing to this disparity by analyzing liver and tumor characteristics in patients with HCC who have a history of hepatitis C virus (HCV) infection. METHODS: Records of patients with HCV and HCC at the authors' institution from 2003 to 2018 were retrospectively reviewed. Race and ethnicity were self-identified. Imaging, laboratory, and pathologic features were compared between Black and non-Black cohorts. RESULTS: Among 1195 individuals with HCC, 390 identified as Black. At the time of HCC diagnosis, Black patients had better liver function, as measured by Child-Pugh score, Model of End-Stage Liver Disease score, histology of nontumor tissue, and fibrosis-4 (FIB-4) score (all P < .05). FIB-4 scores were <3.25 in 31% of Black patients. In addition, Black patients had less early stage HCC (20.2% vs 32.3%; P < .05), larger tumors (median [interquartile range]: 3.5 cm [2.2-6.2 cm] vs 3.1 cm [2.1-5.1 cm]; P < .01), more multiple tumors (median, [interquartile range]: 1 tumor [1-3 tumors] vs 1 tumor [1-2 tumors]; P = .03), more poorly differentiated tumors (30.3% vs 20.5%; P < .05), and more microvascular invasion (67.2% vs 56.5%; P < .05). CONCLUSIONS: Black patients with HCV exposure develop HCC at earlier stages of liver disease than members of other racial groups. Nearly one-third would not qualify for HCC screening using the common FIB-4 cirrhosis threshold. Practice guidelines that stress HCC surveillance for cirrhotic patients with HCV may need to be revised to be more inclusive for Black patients. In addition, tumors in Black patients carry worse prognostic features, and molecular studies are needed to characterize their biologic properties.

BACKGROUND AND OBJECTIVES: Current management guidelines recognize the impact of hepatic versus peritoneal sided gallbladder cancers (GBC) on survival. However, no data exist regarding the significance of anatomic tumor location within the gallbladder. METHODS: We retrospectively analyzed all GBC that underwent surgical resection with curative intent in our health system from 2007 to 2017. We evaluated the effect of anatomic pathologic tumor location (fundus/body, neck, and multifocal) on clinicopathologic, perioperative, and oncologic outcomes. RESULTS: About 97 patients met criteria; 63% fundus/body, 22% multifocal, and 15% neck. Compared with fundus/body, neck tumors more frequently presented with preoperative jaundice (53% vs. 13%, p < .001), were smaller (20 mm vs. 30 mm, p = .068) and had significantly more biliary tree invasion (33% vs. 13%, p = .030) on histopathology. Although tumor characteristics (pTNM stage, liver invasion, lymphovascular invasion, prognostic nutritional index, and grade) were similar, neck tumors had significantly higher rates of R0 resection (53% vs. 11%, p < .001). Rates of adjuvant therapy were similar. Median PFS was similar between cohorts (p = .356). However, median overall survival (OS) was significantly shorter in neck (21 months) than fundus/body tumors (NR > 109 months), p = .015. CONCLUSIONS: Neck tumors were rare, small and more likely to result in jaundice secondary to biliary tree invasion. Despite higher R0 resection rates, these tumors had significantly worse OS.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is effective in select patients with peritoneal metastases of colorectal (CRC) origin. The impact of different biomarkers in predicting recurrence after CRS/HIPEC is unclear. METHODS: Retrospective review of patients who underwent CRS/HIPEC for PC of CRC origin from 03/2007-08/2017. Molecular profile of the primary tumor was obtained from pathology reports, whenever available. RESULTS: Overall, 100 patients underwent CRS/HIPEC for peritoneal metastases of CRC origin. Most patients presented high grade tumor histology (G2/G3, n = 97, 97%), and a majority showed mucinous features (n = 61, 61%). At a median follow-up of 18 months, median DFS for the overall population was 13 months (95% CI 9.6, 16.4). Data reporting at least one mutational analysis was available in 64 patients. Microsatellite stability was detected in 42/50 (84%) patients, mKRAS in 25/51 (49%), and mBRAF in 5/35 (14.3%). On Kaplan-Meier analysis, BRAF was the only mutation associated with poor DFS (16 months, CI 95% 11.7-43.3 vs. 7 months, CI 95% 2.1-11.9, p = .008). On multivariate analysis, mBRAF independently predicted earlier recurrence (p = .032). CONCLUSIONS: In this analysis, mBRAF was independently associated with earlier recurrence in patients undergoing CRS/HIPEC for CRC, leading to dismal median DFS (7 months). Strict patient selection is advisable in these patients.

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an aggressive locoregional treatment for peritoneal carcinomatosis (PC). Studies demonstrate improved perioperative and oncologic outcomes at high-volume centers. METHODS: This study retrospectively analyzed all patients with PC from various malignancies who underwent attempted CRS/HIPEC at the authors' institution from 2007 to 2017. Clinicopathologic, perioperative, and oncologic outcomes of early (2007-2012) and late (2012-2017) experience were compared, and multivariate analyses for factors predictive of perioperative and oncologic outcomes were performed. RESULTS: The study enrolled 388 patients (157 early and 231 late). The late experience contained more appendiceal low-grade mucinous neoplasms (LGMNs; 21% vs 9%) and had a lower Peritoneal Cancer Index (PCI; 10 vs 16). Moreover, achieving a similar rate of CC-0/1 required fewer organ resections, involved shorter operations (298 vs 347 min), and had lower estimated blood loss (EBL) (400 vs 200 ml) (p < 0.05). More procedures were aborted (20% vs 3%; p < 0.01). The late experience had fewer ICU admissions (13% vs. 55%) and a lower perioperative mortality rate (0% vs 3%) (p < 0.05). In the multivariate analyses, PCI and number of organ resections were independent predictors of multiple perioperative outcomes [EBL, operating room time, intensive care unit (ICU) admission, ICU length of stay (LOS), overall LOS]. Survival was significantly longer in the late cohort (median overall survival: NR vs 31 months; progression-free survival: 22 vs 11 months; p < 0.01), even after control for tumor histology. CONCLUSIONS: At the authors' high-volume center, with increased surgeon and institutional experience over time, perioperative and oncologic outcomes have improved significantly for patients undergoing CRS/HIPEC for PC.

BACKGROUND: Pleural recurrence after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is rare and poorly delineated. Specifically, data are limited on the effect that diaphragmatic peritoneal stripping versus full-thickness resection has on the nature of ipsilateral pleural recurrence and postoperative morbidity. METHODS: Patients with peritoneal carcinomatosis who underwent CRS/HIPEC were included from a prospectively maintained database. The patients were divided into three cohorts based on surgical management of the diaphragm as follows: diaphragm-stripping (DS) cohort, full-thickness resection (FTR) cohort, and no diaphragm manipulation (ND) cohort. Postoperative morbidity and incidence of ipsilateral pleural recurrence were evaluated. All diaphragmatic defects were closed before abdominal chemoperfusion. RESULTS: The inclusion criteria were met by 409 CRS/HIPEC procedures: 66 in DS, 122 in FTR, and 238 in ND. Ipsilateral pleural recurrence rates did not differ significantly between the three cohorts (DS 6%, FTR 3%, ND 3%; p = 0.470). Postoperative respiratory complications and overall morbidity were significantly greater for the patients who underwent diaphragmatic disruption (stripping and/or resection) than for the patients who did not (p ≤ 0.0001), but the two groups did not differ in terms of 30-day mortality. However, comparison of FTR with DS showed no impact on major morbidity or pleural recurrence. CONCLUSION: Although patients undergoing surgical manipulation of the diaphragm during CRS/HIPEC experienced significantly greater morbidity, diaphragmatic stripping did not differ from full-thickness resection in terms of grades 3 and 4 complications or incidence of ipsilateral pleural recurrences. When deemed necessary to achieve complete cytoreduction, full-thickness diaphragmatic resection should be undertaken. In addition, the data support the observation that definitive repair of the diaphragmatic defect before abdominal chemoperfusion does not adversely influence ipsilateral pleural recurrence.

BACKGROUND: Low-grade appendiceal mucinous neoplasms (LAMNs) are tumors that often present with widespread mucin in the peritoneal cavity (pseudomyxoma peritonei [PMP]). Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are effective treatment, but no published recommendations exist regarding surveillance. METHODS: Data from prospective databases of patients who underwent CRS-HIPEC from 2001 to 2017 at two high-volume institutions were retrospectively analyzed. Patients who underwent complete CRS-HIPEC for PMP secondary to LAMN were included in the analysis. Pathologic examination confirmed the diagnosis of LAMN. Cases of mucinous adenocarcinomas and neuroendocrine tumors (goblet cell carcinoids) were excluded. RESULTS: The study enrolled 156 patients. The median peritoneal cancer index (PCI) was 18 (interquartile range IQR1-3, 12-23), and 125 patients (80.1%) had a CC0 cytoreduction. According to American Joint Committee on Cancer (AJCC) grading, 152 patients (97.4%) presented with acellular mucin or G1 implants, 2 patients (1.3%) presented with G2 disease, and 2 patients (1.3%) presented with G3 disease. During the follow-up period (median, 45 months; IQR1-3 23-76 months), 23 patients (14.7%) experienced recurrence. All the recurrences were peritoneal and occurred within 5 years. The 1-, 3-, and 5-year disease-free survival (DFS) rates were respectively 95.5%, 83.4%, and 78.3%. Univariate Cox regression analysis showed that higher PCI scores (p < 0.001), a CC1 cytoreduction (p = 0.005), and higher preoperative levels of carcinoembryonic antigen (CEA) (p = 0.012) and CA-125 (p = 0.032) correlated with a shorter DFS. Only higher PCI scores independently predicted earlier recurrences (p < 0.001). CONCLUSION: Most patients had recurrence within 3 years after CRS-HIPEC, and none after 5 years. High PCI was the only independently significant variable. The study findings support intensive surveillance (every 3-6 months) with tumor markers and imaging methods during the first 3 years, and annual surveillance thereafter, with follow-up assessment after 5 years yielding limited benefit.

BACKGROUND: Hepatopancreaticobiliary malignancies with peritoneal carcinomatosis exhibit poor survival with current therapies: hepatocellular carcinoma 11 months with sorafenib, and pancreaticobiliary 9-14 months with systemic chemotherapy. However, limited data exist on the utility of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in these patients. METHODS: We retrospectively reviewed our institutional hepatopancreaticobiliary malignancies with peritoneal carcinomatosis which underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy from 2007 to 2017 and analyzed perioperative and oncologic outcomes. RESULTS: Seventeen patients were included: 9 hepatocellular carcinoma, 8 pancreaticobiliary (4 cholangiocarcinoma, 3 gallbladder, 1 pancreatic). Peritoneal cancer index, number of organs resected, completeness of cytoreduction, and 30-day morbidity were equivalent. Hepatocellular carcinoma received significantly less neoadjuvant therapy (11%, p = 0.008), though adjuvant therapy rates were similar. At a median follow-up of 15 months, progression-free survival was similar amongst all cohorts. However, overall survival was longer in hepatocellular carcinoma (42 months vs. cholangiocarcinoma 19 months, gallbladder 8 months, pancreatic 15 months, p = 0.206) with 59% 3-year overall survival (vs. 0% cholangiocarcinoma, 0% gallbladder, 0% pancreatic). CONCLUSIONS: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy may offer a survival benefit in select hepatocellular carcinoma patients with peritoneal carcinomatosis, though has dubious utility in pancreaticobiliary malignancies.

BACKGROUND: Appendiceal and colorectal cancers with peritoneal carcinomatosis (PC) can derive benefit from cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). However, its role in gastric and small bowel malignancies remains undefined. METHODS: We retrospectively analyzed 251 gastrointestinal adenocarcinomas with PC which underwent CRS/HIPEC at our institution from 2007 to 2017. We compared outcomes of gastric, small bowel, appendiceal, and colorectal cohorts. RESULTS: Thirty-one gastric, 8 small bowel, 91 appendiceal, and 121 colorectal cohorts were included. More gastric cancers (90%) received neoadjuvant chemotherapy than any other cohort, p = 0.002. Although colorectal had the lowest peritoneal cancer index (PCI) (9) and appendiceal the highest (16), all cohorts underwent similar rates of organ resection and complete cytoreduction. Length of stay (p = 0.005) and major perioperative morbidity (Clavien III/IV, p = 0.011) were significantly higher in gastric and small bowel. Median overall survival (OS, p < 0.001) was significantly shorter in gastric (13 months) and small bowel (9 months) than in appendiceal (33 months) and colorectal (42 months) cohorts. On multivariate analysis, complete cytoreduction and PCI score were significant predictors of OS, p < 0.05. CONCLUSIONS: Primary tumor origin significantly affects outcomes after CRS/HIPEC for gastrointestinal malignancies. Though there was a survival benefit in appendiceal and colorectal, gastric and small bowel survival was comparable to systemic chemotherapy.

BACKGROUND: Colonoscopy to detect colorectal cancer (CRC) is recommended starting at age 50 years; however, CRC rates are increasing in the prescreening population. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has been proven effective in select patients with peritoneal carcinomatosis (PC) from CRC, although it has not been evaluated specifically in patients < 50 years. METHODS: CRC patients aged < 50 years at diagnosis undergoing CRS/HIPEC 2007-2017 were compared with those aged ≥ 50 years. Age distribution was analyzed in patients undergoing colectomy alone versus CRS/HIPEC for CRC 1993-2013. RESULTS: A total of 98 patients underwent CRS/HIPEC, of which 44% were < 50 years. Younger patients were more likely to present with synchronous peritoneal metastases (p = 0.050). Receipt of perioperative chemotherapy was comparable (p = not significant [NS]). Charlson Comorbidity Index and ECOG score were similar (p = NS). Tumor grade was similar (p = NS). Peritoneal Carcinomatosis Index, total organs resected, and anastomoses created were comparable (p = NS). Major Clavien-Dindo morbidity and LOS were similar (p = NS). Younger patients survived longer after CRS/HIPEC (p = 0.011). Demographic data from patients undergoing colectomy (n = 225) and CRS/HIPEC (n = 98) showed that age < 50 years was increasingly common with the more aggressive procedure (9% and 44% respectively, p < 0.001). CONCLUSIONS: Younger patients with PC from CRC presented more often with peritoneal metastases at the time of diagnosis. Yet despite similar perioperative features at CRS/HIPEC, they survived longer than older patients. Patients undergoing CRS/HIPEC are overall younger than those undergoing index colectomy.

RESUMO
BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is effective in select patients with peritoneal carcinomatosis (PC). Signet ring cell (SRC) pathology is associated with poor prognosis. The role of CRS/HIPEC in this population is unclear. METHODS: Patients diagnosed with PC due to appendiceal (AC), colorectal (CRC), and gastric cancer (GC) undergoing CRS/HIPEC 2007-2016 were included. RESULTS: A total of 268 patients were referred for CRS/HIPEC. Of the 204 patients who underwent complete CRS/HIPEC, 101 (49.5%) had AC, 85 (41.7%) CRC, and 18 (8.8%) GC. Patients with GC had higher rates of SRC pathology than AC and CRC: 12 (66.7%) vs 16 (15.8%) and 10 (11.7%). The 3-year survival rate after CRS/HIPEC was 5.7% for the SRC group and 66.1% for the non-SRC group (P < 0.001). This was true for both AC and CRC subgroups (P < 0.001 for both). Overall, patients with SRC were more likely to have a peritoneal carcinomatosis index (PCI) score > 15 (P = 0.046). Upon multivariate analysis of the SRC population, PCI > 20 (P = 0.007) and GC (P = 0.008) were found to be independent predictors of poor overall survival. CONCLUSIONS: Performing CRS/HIPEC for PC from gastrointestinal malignancies presenting SRC features is recommended on patients with select diseases of appendiceal and colorectal origins.

BACKGROUND: Current guidelines recommend harvesting a total lymph node count (TLNC) ≥6 from portal lymphadenectomy in ≥pT1b gallbladder cancers (GBC) for accurate staging and prognostication. This study aimed to determine nodal yields from portal lymphadenectomy and identify measures to maximize TLNC. METHODS: We retrospectively reviewed all ≥pT1b GBC which underwent resection with curative intent including portal lymphadenectomy at our specialized HPB center from 2007 to 2017. We compared outcomes of TLNC < 6 and TLNC ≥ 6 cohorts and determined factors predictive of TLNC. RESULTS: Of 92 patients, 20% had a TLNC ≥ 6 (IQR 7-11) and 9% had no nodes found on pathology. Malignant lymphadenopathy was twice as common in TLNC ≥ 6 as TLNC < 6 (p = 0.003) most frequently from portal, cystic and pericholedochal stations. On logistic regression analysis, concomitant liver resection was an independent predictor of higher TLNC [4b/5 wedge resection (OR 0.166, CI 0.057-0.486, p = 0.001) extended hepatectomy (OR 0.065, CI 0.012-0.340, p = 0.001)]; biliary resection and en bloc adjacent organ resection were not. CONCLUSION: At our center, prior to current guidelines, a TLNC≥6 was not met in 80% undergoing portal lymphadenectomy for ≥ pT1b GBC. To increase nodal yield, future guidelines should consider including additional lymph node stations and incorporation of frozen section analysis.

BACKGROUND: NSQIP data show that half of distal pancreatectomies (DP) are performed by a minimally invasive approach (MIS). Advantages have been demonstrated for MIS DP, yet comparative cost data are limited. Outcomes and cost were compared in patients undergoing open (ODP), laparoscopic (LDP), and robotic (RDP) approaches at a single institution. METHODS: A retrospective review was performed on patients undergoing DP between 1/2010-5/2016. Analysis was intention-to-treat, and cost was available after 1/2013. RESULTS: DP was performed in 374 patients: ODP = 85, LDP = 93, and RDP = 196. Operating time was lowest in the RDP cohort (p < 0.0001). ODP had higher estimated blood loss (p < 0.0001) and transfusions (p < 0.0001) than LDP and RDP. LDP had greater conversions to open procedures than RDP (p = 0.001). Postoperative outcomes were similar between groups. Length of stay was higher in the ODP group (p = 0.0001) than LDP and RDP. Overall cost for the ODP was higher than the RDP and LDP group (p = 0.002). On multivariate analysis, RDP reduced LOS (ODP: Odds = 6.5 [p = 0.0001] and LDP: Odds = 2.1 [p = 0.036]) and total cost (ODP: Odds = 5.7 [p = 0.002] and LDP: Odds = 2.8 [p = 0.042]) independently of all demographics and illness covariates. CONCLUSIONS: A robotic approach is associated with reduced length of stay and cost compared to open and laparoscopic procedures.

BACKGROUND: Postoperative pancreatic fistulas (POPFs) are potentially morbid complications that often require therapeutic interventions. Distal pancreatectomy performed during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemoperfusion (HIPEC) puts patients at risk for POPF. The authors hypothesized that POPFs are more severe after CRS/HIPEC than after pancreatectomy alone. METHODS: Clinicopathologic and perioperative details, including POPF by International Study Group of Pancreatic Fistula criteria (ISGPF), and oncologic outcomes for patients undergoing distal pancreatectomy during CRS/HIPEC for peritoneal carcinomatosis of appendiceal (n = 31) or colorectal (n = 23) origin (HIPEC group) were compared with those for patients undergoing minimally invasive or open distal pancreatectomy without HIPEC (n = 66) for locally resectable pancreatic adenocarcinoma (non-HIPEC group). RESULTS: The incidence of POPF was similar between the HIPEC and non-HIPEC groups (26 %). The severity of POPF according to the ISGPF criteria was significantly worse in the HIPEC group. The HIPEC patients had 13 grade B fistulas and 1 grade C fistula compared with 12 grade A fistulas and 4 grade B fistulas in the non-HIPEC group. The HIPEC patients with POPF did not differ in the extent of their CRS, peritoneal cancer index, length of hospital stay, or other postoperative complications from the the HIPEC patients without POPF. The HIPEC patients with colorectal carcinomatosis who experienced POPF had higher disease recurrence in the first year after CRS/HIPEC than those without POPF. CONCLUSION: The findings showed that POPFs are more severe when distal pancreatectomy is combined with CRS/HIPEC. Moreover, selective use of distal pancreatectomy is important during CRS/HIPEC because POPFs may increase early disease recurrence for patients with colorectal carcinomatosis.
