RESUMO
BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is increasingly performed for peritoneal surface malignancies but remains associated with significant morbidity. Scant research is available regarding the impact of insurance status on postoperative outcomes. METHODS: Patients undergoing CRS/HIPEC between 2000 and 2017 at 12 participating sites in the US HIPEC Collaborative were identified. Univariate and multivariate analyses were used to compare the baseline characteristics, operative variables, and postoperative outcomes of patients with government, private, or no insurance. RESULTS: Among 2268 patients, 699 (30.8%) had government insurance, 1453 (64.0%) had private, and 116 (5.1%) were uninsured. Patients with government insurance were older, more likely to be non-white, and comorbid (p < 0.05). Patients with government (OR: 2.25, CI: 1.50-3.36, p < 0.001) and private (OR: 1.69, CI: 1.15-2.49, p = 0.008) insurance had an increased risk of complications on univariate analysis. There was no independent relationship on multivariate analysis. An American Society of Anesthesiologists score of 3 or 4, peritoneal carcinomatosis index score >15, completeness of cytoreduction score >1, and nonhome discharge were factors independently associated with a postoperative complication. CONCLUSION: While there were differences in postoperative outcomes between the three insurance groups on univariate analysis, there was no independent association between insurance status and postoperative complications after CRS/HIPEC.

BACKGROUND: Total pancreatectomy and islet cell autotransplantation (TPIAT) offers an effective, lasting solution for the management of chronic pancreatitis up to 5-years post-operatively. Our aim was to assess durability of TPIAT at 10-years. METHODS: Patients undergoing TPIAT for chronic pancreatitis eligible for 10-year follow-up were included. Primary outcomes, including endocrine function and narcotic requirements, were reported at 5-, 7.5-, and 10-years post-operatively. RESULTS: Of the 231 patients who underwent TPIAT, 142 met inclusion criteria. All patients underwent successful TPIAT with an average of 5680.3 islet equivalents per body weight. While insulin independence tended to decrease over time (25.7% vs. 16.0% vs. 10.9%, p = 0.11) with an increase in HbA1C (7.6% vs. 8.2% vs. 8.4%, p = 0.09), partial islet function persisted (64.9% vs. 68.0% vs. 67.4%, p = 0.93). Opioid independence was achieved and remained durable in the majority (73.3% vs. 72.2% vs. 75.5%, p = 0.93). Quality of life improvements persisted, with 85% reporting improvement from baseline at 10-years. Estimated median overall survival was 202.7 months. CONCLUSION: This study represents one of the largest series reporting on long-term outcomes after TPIAT, demonstrating excellent long-term pain control and durable improvements in quality of life. Islet cell function declines over time however stable glycemic control is maintained.

BACKGROUND: T2 intrahepatic cholangiocarcinoma (ICC) is defined as a solitary tumors with vascular invasion or multifocal tumors including satellite lesions, multiple lesions, and intrahepatic metastases. This study aimed to evaluate the prognosis associated with multifocal tumors. METHODS: The National Cancer Database was queried from 2004 to 2017 for patients with non-metastatic ICC. The patients were grouped based on T2 staging, multifocality, and lymph node involvement. RESULTS: The study enrolled and classified 4887 patients into clinical (c) stage groups as follows: 15.2% with solitary T2N0 (sT2N0) tumors, 21.3% with multifocal T2N0 (mT2N0) tumors, and 63.5% with node-positive (TxN1) disease. Patients with (c)sT2N0 tumors had higher rates of surgical resection than those with (c)mT2N0 or (c)TxN1 disease (33.5% vs 19.7% vs 15.0%; p < 0.01). Median overall survival (OS) was better for the patients with (c)sT2N0 tumors than for those with multifocal and node-positive disease (15.4 vs 10.4 vs 10.4 months; p < 0.01). On multivariate analysis, (c)sT2N0 tumors were associated with better OS than (c)mT2N0 tumors [hazard ratio (HR), 1.31; 95% confidence interval (CI), 1.17-1.46; p < 0.01] or (c)TxN1 disease (HR,1.41; 95% CI 1.28-1.56; p < 0.01). In a subset analysis based on pathologic (p) staging of patients who underwent surgical resection with regional lymphadenectomy, multivariate analysis demonstrated that (p)sT2N0 tumors were associated with better OS than (p)mT2N0 tumors (HR,1.40; 95% CI 1.03-1.92; p = 0.03) or (p)TxN1 disease (HR, 2.05; 95% CI 1.62-2.58; p < 0.01). CONCLUSIONS: Multifocal T2N0 ICC is associated with poor OS and has a disparate prognosis compared with solitary T2N0 disease, even among patients who undergo resection. Future staging criteria should account for the poor outcomes associated with multifocal ICC.

BACKGROUND: Circumferential resection margin (CRM) status is an important predictor of outcomes after rectal cancer operation, and is influenced not only by operative technique, but also by incorporation of a multidisciplinary treatment strategy. This study sought to develop a risk-adjusted quality metric based on CRM status to assess hospital-level performance for rectal cancer operation. STUDY DESIGN: We conducted a retrospective observational cohort study of 58,374 patients with resected stage I to III rectal cancer within 1,303 hospitals who were identified from the National Cancer Database (2010 to 2015). The number of observed cases with a positive CRM (≤ 1 mm) was divided by the risk-adjusted expected number of cases with positive CRM to form the observed-to-expected (O/E) ratio. Secondary endpoint was overall survival. RESULTS: The overall rate of CRM positivity was 15.9%. Based on the O/E ratio for 1,139 hospitals, 147 (12.9%) and 103 (9.0%) were significantly worse and better performers, respectively. The majority of hospitals (n = 570) performed as expected. Positive CRMs using criteria of 0 mm and 0.1 to 1 mm were associated with a significantly shorter 5-year overall survival of 49% and 63.5% (hazard ratio 1.67; 95% CI, 1.57 to 1.76 and hazard ratio 1.19; 95% CI, 1.12 to 1.26) than negative CRM > 1 mm of 74.1% (all p < 0.001). CONCLUSIONS: CRM-based O/E ratio is a robust hospital-based quality measure for rectal cancer operation. It allows facilities to compare their performance with that of centers of similar characteristics and helps identify underperforming, at-risk, and high-performing centers. National quality-improvement initiatives for rectal cancer should focus on ensuring high-quality data collection and providing ready access to risk-adjusted comparative metrics.

BACKGROUND: No guidelines exist for surveillance following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for appendiceal and colorectal cancer. The primary objective was to define the optimal surveillance frequency after CRS/HIPEC. METHODS: The U.S. HIPEC Collaborative database (2000-2017) was reviewed for patients who underwent a CCR0/1 CRS/HIPEC for appendiceal or colorectal cancer. Radiologic surveillance frequency was divided into two categories: low-frequency surveillance (LFS) at q6-12mos or high-frequency surveillance (HFS) at q2-4mos. Primary outcome was overall survival (OS). RESULTS: Among 975 patients, the median age was 55 year, 41% were male: 31% had non-invasive appendiceal (n = 301), 45% invasive appendiceal (n = 435), and 24% colorectal cancer (CRC; n = 239). With a median follow-up time of 25 mos, the median time to recurrence was 12 mos. Despite less surveillance, LFS patients had no decrease in median OS (non-invasive appendiceal: 106 vs. 65 mos, p < 0.01; invasive appendiceal: 120 vs. 73 mos, p = 0.02; colorectal cancer [CRC]: 35 vs. 30 mos, p = 0.8). LFS patients had lower median PCI scores compared with HFS (non-invasive appendiceal: 10 vs. 19; invasive appendiceal: 10 vs. 14; CRC: 8 vs. 11; all p < 0.01). However, on multivariable analysis, accounting for PCI score, LFS was still not associated with decreased OS for any histologic type (non-invasive appendiceal: hazard ratio [HR]: 0.28, p = 0.1; invasive appendiceal: HR: 0.73, p = 0.42; CRC: HR: 1.14, p = 0.59). When estimating annual incident cases of CRS/HIPEC at 375 for non-invasive appendiceal, 375 invasive appendiceal and 4410 colorectal, LFS compared with HFS for the initial two post-operative years would potentially save $13-19 M/year to the U.S. healthcare system. CONCLUSIONS: Low-frequency surveillance after CRS/HIPEC for appendiceal or colorectal cancer is not associated with decreased survival, and when considering decreased costs, may optimize resource utilization.

BACKGROUND: Variability in blood use after pancreaticoduodenectomy and the associated impact on readmission, mortality, and cost is not well understood at the national level. METHODS: The University HealthSystem Consortium database was queried for all pancreaticoduodenectomies performed between the years 2011-2013 (nâ¯=â¯9,582). Patients were grouped according to transfusion requirements into none (0 units, 64%), low (1-2 units, 15%), medium (3-5 units, 13%), and high (>5 units, 8%). Multivariable analyses were used to determine predictors of increased transfusions, readmission, in-hospital mortality, and cost. RESULTS: Of the patients undergoing pancreaticoduodenectomy, 36% received blood perioperatively. Patients with high transfusion requirements were less often white, more often male, and had a higher severity of illness (all P < .01). High transfusion requirements correlated with higher readmission rates (OR 1.23, Pâ¯=â¯.03), cost (RR 1.84, P < .01), length of stay (18 vs. 13 vs. 10 vs. 8 days, P < .01), and in-hospital mortality (12.5% vs. 3.1% vs. 0.5% vs. 0.4%, P < .01). Higher-volume surgeons demonstrated lower transfusion requirements (OR 0.61, P < .01). CONCLUSION: Significant variability exists nationally in transfusion practices for patients undergoing pancreaticoduodenectomy, which may be driven most by severity of illness and surgeon volume. Efforts to reduce such variability could lead to improved outcomes and healthcare cost savings.

BACKGROUND: Feeding jejunostomy tubes (J-tube) are often placed during gastrectomy for cancer to decrease malnutrition and promote delivery of adjuvant therapy. We hypothesized that J-tubes actually are associated with increased complications and do not improve nutritional status nor increase rates of adjuvant therapy. METHODS: One hundred thirty-two patients were identified from a prospectively maintained database that underwent gastric resection for gastric adenocarcinoma between 1/00 and 3/11 at one institution. Pre- and postoperative nutritional status and relevant intraoperative and postoperative parameters were examined. RESULTS: Median age was 64 years (range 23-85). Forty-six (35%) underwent a total and 86 (65%) a subtotal gastrectomy. J-tubes were placed in 66 (50%) patients, 34 of whom underwent a subtotal and 32 a total gastrectomy. Preoperative nutritional status was similar between J-tube and no J-tube groups as measured by serum albumin (3.5 vs. 3.4 g/dL). Tumor grade, T, N, and overall stage were similar between groups. J-tube placement was associated with increased postop complications (59% vs. 41%, P = 0.04) and infectious complications (36% vs. 17%, P = 0.01), of which majority were surgical site infections. J-tubes were associated with prolonged length of stay (13 vs. 11 days; P = 0.05). There was no difference in postoperative nutritional status as measured by 30, 60, and 90-day albumin levels and the rate of receiving adjuvant therapy was similar between groups (J-tube: 61%, no J-tube: 53%, P = 0.38). Multivariate analyses revealed J-tubes to be associated with increased postop complications (HR: 4.8; 95% CI: 1.3-17.7; P = 0.02), even when accounting for tumor stage and operative difficulty and extent. Subset analysis revealed J-tubes to have less associated morbidity after total gastrectomy. CONCLUSION: J-tube placement after gastrectomy for gastric cancer may be associated with increased postoperative complications with no demonstrable advantage in receiving adjuvant therapy. Routine use of J-tubes after subtotal gastrectomy may not be justified, but may be selectively indicated in patients undergoing total gastrectomy. A prospective trial is needed to validate these results.
