BACKGROUND: Metabolic syndrome is associated with poorer postoperative outcomes after various abdominal operations. However, the impact of metabolic syndrome on outcomes after colorectal cancer surgery remains poorly described. OBJECTIVE: The purpose of this study was to determine the association between metabolic syndrome and short-term postoperative outcomes in patients undergoing elective colorectal cancer surgery. DESIGN: This was a retrospective cohort study. SETTINGS: This study used a national multicenter database. PATIENTS: Adult patients who underwent elective colectomy for colorectal cancer from 2010 to 2016 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. MAIN OUTCOME MEASURES: Thirty-day postoperative mortality and morbidity, unplanned reoperation, unplanned readmission, operative time, and length of stay were measured. RESULTS: A total of 91,566 patients were analyzed; 7603 (8.3%) had metabolic syndrome. On unadjusted analysis, metabolic syndrome was associated with an increased risk of 30-day overall morbidity, pulmonary complications, renal complications, septic complications, cardiac complications, wound complications, blood transfusion, longer length of stay, and unplanned readmissions. On multivariable analysis, metabolic syndrome remained significantly associated with renal complications (OR = 1.44 (95% CI, 1.29–1.60)), superficial surgical site infection (OR = 1.46 (95% CI, 1.32–1.60)), deep surgical site infection (OR = 1.40 (95% CI, 1.15–1.70)), wound dehiscence (OR = 1.47 (95% CI, 1.20–1.80)), and unplanned readmissions (HR = 1.24 (95% CI, 1.15–1.34)). The risks of overall morbidity, cardiac and septic complications, and prolonged length of stay for laparoscopic procedures were significantly associated with diabetes mellitus rather than metabolic syndrome as a composite entity. LIMITATIONS: This study was limited by its retrospective design and inability to analyze outcomes beyond 30 days. CONCLUSIONS: Patients with metabolic syndrome undergoing elective surgery for colorectal cancer have an increased risk of 30-day postoperative renal complications, wound complications, and unplanned hospital readmissions. A multidisciplinary approach involving lifestyle modifications and pharmacologic interventions to improve the components of metabolic syndrome should be implemented preoperatively for these patients.

Background Age, tumor size and location, overall health, and patient preference are primary considerations driving treatment decision-making for intracranial meningiomas. However, even for the same individual patient, treatment recommendations may vary between centers and providers. Objective To study associations between geography, disease presentation, and management of intracranial meningioma in the United States. Methods The population-based Surveillance, Epidemiology, and End Results(SEER) data were queried between 2004 and 2014 for cases of intracranial meningioma. Results A total of 65,808 patients with intracranial meningioma were identified. Univariate analyses demonstrated strong associations between geographic location, age, and size of tumor at presentation. The mean age for all registries was 64.2 years, with a range from 62.0 (Utah registry) to 66.6 (Detroit registry). The greatest proportion of small tumors (<1 cm) were identified in the Utah registry (13.9% of tumors), while the greatest proportion of large tumors (> 4cm) were noted in the Hawaii registry (30.7% of tumors). Multivariable analysis demonstrated that the impact of geography on treatment selection was just as important as other established variables. For example, the distribution in tumor size between New Mexico and Greater California registries is nearly identical; however, the odds ratio for surgery was 1.5 times greater for the New Mexico population. Conclusion These data suggest that disease presentation and treatment are significantly influenced by regional referral patterns, provider or institutional treatment preferences, and regional availability of subspecialty expertise. Understanding such biases is important for patients, referring physicians, and treatment providers in an effort to provide balanced counseling and treatment.

SummaryBendamustine (B) with rituximab (R) is a standard frontline treatment for medically fit follicular lymphoma (FL) patients. The safety and efficacy of maintenance rituximab (MR) after BR induction has not been formally compared to observation for FL, resulting in disparate practice patterns. Prospective trials have shown benefit of MR after R‐CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) or R‐CVP (rituximab, cyclophosphamide, vincristine, prednisone), yet recent data from the GALLIUM study comparing outcomes of patients treated with chemotherapy with R or obinutuzumab (G) showed higher than anticipated fatal adverse events with BR/BG. In order to assess the efficacy and tolerability of MR after BR, we retrospectively collected data on 640 newly diagnosed patients treated with FL. We found that patients who achieved partial remission (PR) after ≥4 cycles of BR had improved duration of response (DOR) with MR vs. no maintenance, whereas those in complete remission did not. These findings were confirmed in a validation cohort. In the entire study population, the known fatal adverse event rate after BR was 2·5% and did not significantly differ in those receiving MR versus no maintenance. [Correction added on 14 January 2019, after online publication: The preceding sentence has been corrected in this current version.] Within the limitations inherent to retrospective analysis, these data suggest that FL patients with a PR to BR experience prolongation of remission with MR with an acceptable safety profile.

Abstract Vitreoretinal lymphoma (VRL) management remains a challenge. We present 72 patients with VRL, diagnosed at Mayo Clinic between 1990‐2018. Three nondiffuse large B‐cell lymphoma (DLBCL) histology cases were excluded. Among 69 DLBCL, 33 patients had primary VRL (PVRL), 18 concurrent intraocular and central nervous system (CNS) or systemic disease and 18 secondary VRL. Patients received intraocular chemotherapy (intraocular injections of rituximab or metothrexate or steroids or in combination), radiotherapy, systemic or combined systemic plus intraocular treatment in 9, 10, 35, and 15 cases, respectively. Among primary and concurrent VRL, median failure free survival (FFS), CNS relapse‐free survival (CNS‐RFS) and overall survival (OS) were: 1.8, 4.9, and 4.1 years, respectively; among PVRL, median FFS, CNS‐RFS, and OS were: 2.6 year, Not Reached and 9.3 year, respectively. No CNS relapse occurred beyond 4 years in PVRL. Median OS for patients diagnosed between 1990 and 1999 vs between 2000 and 2018 was 1.5 vs 9.4 years, respectively ( P = .0002). OS was significantly higher in PVRL, as compared with concurrent VRL ( P = .04). Previous immunosuppression and poor performance status were predictive of worse outcome. In PVRL, a combined systemic and intraocular therapy showed higher FFS ( P = .002) and CNS‐RFS ( P = .003), but no differences in OS. Among 18 secondary VRL, at a median follow‐up of 1.1 year after vitreoretinal relapse, median FFS and OS were 0.3 and 1.3 years. An improvement in survival of VRL has been observed over the decades. PVRL should undergo combined systemic and intraocular chemotherapy to prevent CNS progression.
