    ABSTRACT: Background: Leiomyosarcoma arising in the colorectum is a rare malignancy of the smooth muscles accounting for less than 1% of gastrointestinal tumors. Surgery remains the most accepted modality for the treatment of this entity however management of liver metastases remains controversial. Methods & results: From 1998 to 2009 five patients diagnosed with primary leiomyosarcoma of colorectal origin with metastatic liver disease, underwent liver resections at the American University of Beirut Medical Center. The median overall survival was 47 months (range, 7-135 months). Conclusions: Leiomyosarcoma of colorectal origin with liver metastasis is a very rare entity. Long-term survival can be achieved after surgical resection and should be considered for all patients.

    ABSTRACT: Background: Gemcitabine-related pneumonitis (GRP) has been reported relatively frequently for pancreas cancer in the literature; however, underlying risk factors and optimal management remain to be defined. We studied a cohort of patients with GRP and investigated potential predisposing factors in pancreatic cancer patients. Patients and methods: A total 2440 patients at Memorial Sloan Kettering Cancer Center were identified between January 1, 2000, and December 31, 2012, and were screened for grade 2 or higher GRP in an institutional tumor registry and using an ICD billing code database. Demographic and clinical information was extracted by electronic chart review. Results: A total of 28 patients (1.1%) with GRP were identified. Incidence of grade 2, 3, and 4 reactions were 7 (25%), 18 (64%), and 3 (11%), respectively. No GRP-related mortality was observed. Twenty-one patients (75%) reported a history of cigarette smoking. Seventeen patients (61%) were alcohol users. Six patients (21%) were either regular or heavy drinkers. Most patients (93%) had either locally advanced or metastatic disease. Three patients (11%) underwent a diagnostic bronchoscopy, and in 1 patient a diagnosis of organizing pneumonia was established. Morbidity was significant; 3 patients (11%) required treatment in the intensive care unit. All hospitalized patients received steroid treatment. Conclusion: GRP is relatively uncommon but incurs significant morbidity. Potential risk factors include advanced-stage disease, along with smoking and alcohol consumption and possibly underlying lung disease. We recommend a high level of clinical alertness regarding the diagnosis, early pulmonary referral, and cessation of gemcitabine on suspicion of GRP.

    ABSTRACT: Pancreas adenocarcinoma has a median age at diagnosis of 71 years. Limited studies have focused on the treatment of elderly patients with pancreas cancer. An analysis of systemic therapy use, clinical trial participation, and overall outcomes of 237 patients with metastatic pancreas adenocarcinoma ≥ 75 years of age evaluated at Memorial Sloan-Kettering Cancer Center between 2005 and 2013 was undertaken. Median overall survival was 7 months for the entire study population. A total of 197 (83%) patients received systemic therapy, which was significantly associated with longer overall survival (P < .01). No significant difference was detected in survival between age groups 75 to 79, 80 to 84, and ≥ 85 years of age among those who received systemic therapy (P = .49). Seventy-seven (32%) patients participated in a clinical trial of whom 13 (5%) patients were enrolled in a therapeutic trial, including no patients aged ≥ 85 years. Multivariate analysis demonstrated that presence of liver metastases (P < .001), performance status (P < .001), and number of systemic agents (P < .001) were significantly associated with survival. Receipt of systemic therapy was associated with longer survival in elderly patients ≥ 75 years of age with metastatic pancreas adenocarcinoma. Therapeutic clinical trial participation among these patients was low and future development of prognostic models for appropriate patient selection is warranted. Copyright © 2015 Elsevier Inc.

    ABSTRACT: Background Pancreaticoduodenectomy is an increasingly common procedure performed for both benign and malignant disease. There are conflicting data regarding the safety of pancreatic resection in older patients. Potentially modifiable perioperative risk factors to improve outcomes in older patients have yet to be determined. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database for 2008 to 2009 was used for this retrospective analysis. Patients undergoing pancreaticoduodenectomy were identified and divided into those above and below the age of 65. Preoperative risk factors and postoperative morbidity and mortality were evaluated. Results Among 2,045 patients included in this analysis, 994 patients were >65 years (48.6%) while 1,051 were (less than or equal to) 65 years (51.4%). Thirty-day mortality was higher in the older age group compared to the younger age group 3.6% vs. 1.9% respectively, P = 0.017, odds ratio 1.94. Older patients had a higher incidence of unplanned intubation, ventilator support >48 h and septic shock compared with younger patients. On multivariate logistic regression, after adjusting for other 30-day postoperative occurrences (significant at the P <0.1 level) only septic shock was independently associated with a higher odds of mortality, unplanned intubation, and ventilator support >48 h in older patients compared with younger patients. Conclusions This report from a population-based database is the first to highlight postoperative sepsis as an independent risk factor for mortality and morbidity in older patients undergoing pancreatic resection. Careful perioperative management addressing this issue is essential for patients over the age of 65.

    ABSTRACT: The liver’s role in xenobiotic metabolism, i.e., the modification of drugs and toxic foreign compounds, has long served as a putated explanation for inherent drug resistance of hepatocellular carcinoma (HCC). Therefore, it does not come as a surprise that the initial discovery of the multiple-drug resistance gene (MDR) was in liver tissue [1], and hepatocyte cell lines are a natural reservoir for the study of drug resistance.
