Long-term analysis of 2 prospective studies that incorporate mitomycin C into an adjuvant chemoradiation regimen for pancreatic and periampullary cancers.

PURPOSE: The purpose of this study was to report toxicity and long-term survival outcomes of 2 prospective trials evaluating mitomycin C (MMC) with 5-fluorouracil-based adjuvant chemoradiation in resected periampullary adenocarcinoma. METHODS AND MATERIALS: From 1996 to 2002, 119 patients received an adjuvant 4-drug chemotherapy regimen of 5-fluorouracil, leucovorin, MMC, and dipyridamole with chemoradiation on 2 consecutive trials (trials A and B). Trial A patients received upfront chemoradiation (50 Gy split-course, 2.5 Gy/fraction) followed by 4 cycles of the 4-drug chemotherapy with bolus 5-fluorouracil. Trial B patients received 1 cycle of the 4-drug chemotherapy with continuous infusion 5-fluorouracil followed by continuous chemoradiation (45-54 Gy, 1.8 Gy/fraction) and 2 additional cycles of chemotherapy. Cox proportional hazards models were performed to identify prognostic factors for overall survival (OS). RESULTS: Of the 62 trial A patients, 61% had pancreatic and 39% nonpancreatic periampullary carcinomas. Trial B (n = 57) consisted of 68% pancreatic and 32% nonpancreatic periampullary carcinomas. Resection margin and lymph node status were similar for both trials. Median follow-up was longer for trial A than trial B (197.5 vs 107.0 months), with median OS of 32.2 and 24.2 months, respectively. Rates of 3-, 5-, and 10-year OS were 48%, 31%, and 26% in trial A and 32%, 23%, and 9% in trial B. On multivariate analysis, lymph node-positive resection was the strongest prognostic factor for OS. A pancreatic primary and positive margin status were also associated with inferior survival (P < .05). Rates of grade ≥3 treatment-related toxicity in trials A and B were 2% and 7%, respectively. CONCLUSIONS: This is the first study to report long-term outcomes of MMC with 5-fluorouracil-based adjuvant chemoradiation in periampullary cancers. Because MMC may be considered in DNA repair-deficient carcinomas, randomized trials are needed to determine the true benefit of adjuvant MMC.

The economic impact of surgical care for morbidly obese endometrial cancer patients: a nationwide study.

BACKGROUND: Obesity significantly impacts the cost of cancer treatment, yet the impact of morbid obesity on inpatient hospital charges related to endometrial cancer treatment is not well-defined. OBJECTIVES: The purpose of this study was to determine the charges that are associated with inpatient surgery, hospitalization, and postoperative care of morbidly obese patients with endometrial cancer. STUDY DESIGN: Data were obtained from the National Inpatient Sample from 2010. Chi-square test, t-test, and linear regression were used for statistical analyses. RESULTS: Six thousand five hundred sixty patients who underwent hysterectomy for endometrial cancer were identified. Mean age was 62 years (range, 22-99 years). The majority were white (78%), and the remainder were black (10%), Hispanic, (8%), Asian (3%), and Native American (1%). Insurance types were private (45%), Medicare (45%), Medicaid (5%), and uninsured (7%). One thousand eighty-eight of these patients (17%) were coded as morbidly obese. The mean postoperative stay for the morbidly obese was 4.0 days (range, 0-46 days) compared with 3.5 days (range, 0-81 days) for the non-morbidly obese patients (P < .01). Morbidly obese patients required more intensive care with mechanical ventilation (5.5% vs 1.6%; P < .01). The median hospital charges were higher for morbidly obese patients compared with their counterparts ($46,654 vs $41,164; P < .01). After adjustment for charges that were associated with insurance type, hospital type, and the surgery that was performed, the incremental increase in hospital charges that were associated with treating the morbidly obese patient was $5096 per patient (95% confidence interval, $2593-$7598; P < .01). CONCLUSION: In this economic analysis, the health care charges that were associated with inpatient endometrial cancer treatment in the morbidly obese patient was significantly higher compared the non-morbidly obese patient. Resources are needed to support the needs of this population, and programs to encourage weight loss and optimize general health should be encouraged.

Complete resolution of postoperative hemiparesis following carotid endarterectomy with therapeutic hypothermia: a case study and literature review.

Therapeutic hypothermia is indicated in a number of traumatic brain injuries as well as for cardiovascular shock (Warner DS, James ML, Laskowitz, et al. Translational research in acute central nervous system injury: lessons learned and the future. JAMA Neurol 2014;71:1311-1318), but it has been limited in its application to acute ischemic stroke. We present the case of a 65-year-old woman with a clinical cerebrovascular accident following a right carotid endarterectomy who was treated with a 24-hr hypothermia protocol and had a full recovery. The hypothermia protocol utilized on this patient and a review of the literature surrounding hypothermia in the setting of ischemic stroke are presented.

Survival differences in women with serous tubal, ovarian, peritoneal, and uterine carcinomas.

OBJECTIVE: The fallopian tube has been implicated as the primary origin of pelvic serous cancers. We proposed to determine the survival outcomes of serous tubal, ovarian, peritoneal, and uterine cancer patients. STUDY DESIGN: Data were obtained from the National Cancer Institute between 2004 and 2009. Kaplan-Meier and Cox proportional hazards models were used for analysis. RESULTS: Of 12,336 high-grade serous cancer patients, 563 were tubal (TC), 8560 ovarian (OC), 1037 primary peritoneal (PPC), and 2176 uterine cancer (USC). The median ages of these patients were 63 vs 62 vs 67 vs 68 years, respectively. The majority were white (89% vs 88% vs 91% vs 74%). The overall 5 year, disease-specific survival was 37%. The survivals of those with TC, OC, PPC, and USC were 50%, 37%, 26%, and 40% (P < .01). There was no detailed staging on PPC cancers. Adjusted for stage, the survival of those with stage I, II, III, and IV TC were 73%, 62%, 44%, and 22% (P < .01), OC were 83%, 64%, 34%, and 15% (P < .01), and USC were 88%, 72%, 55%, and 17% (P < .01). On multivariate analysis, younger age, white race, earlier stage, and tubal origin were independent predictors for improved survival. CONCLUSION: In advanced-staged serous cancer patients, tubal cancer patients have better survivals compared with ovarian, peritoneal, and uterine cancer.
