Purpose: Pseudomyxoma peritonei (PMP) originating from an appendiceal mucinous neoplasm remains a biologically heterogeneous disease. The purpose of our study was to evaluate outcome and long-term survival after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) consolidated through an international registry study. Patients and Methods: A retrospective multi-institutional registry was established through collaborative efforts of participating units affiliated with the Peritoneal Surface Oncology Group International. Results: Two thousand two hundred ninety-eight patients from 16 specialized units underwent CRS for PMP. Treatment-related mortality was 2% and major operative complications occurred in 24% of patients. The median survival rate was 196 months (16.3 years) and the median progression-free survival rate was 98 months (8.2 years), with 10- and 15-year survival rates of 63% and 59%, respectively. Multivariate analysis identified prior chemotherapy treatment (P = .001), peritoneal mucinous carcinomatosis (PMCA) histopathologic subtype (P = .001), major postoperative complications (P = .008), high peritoneal cancer index (P = .013), debulking surgery (completeness of cytoreduction [CCR], 2 or 3; P = .001), and not using HIPEC (P = .030) as independent predictors for a poorer progression-free survival. Older age (P = .006), major postoperative complications (P = .001), debulking surgery (CCR 2 or 3; P = .001), prior chemotherapy treatment (P = .001), and PMCA histopathologic subtype (P = .001) were independent predictors of a poorer overall survival. Conclusion: The combined modality strategy for PMP may be performed safely with acceptable morbidity and mortality in a specialized unit setting with 63% of patients surviving beyond 10 years. Minimizing nondefinitive operative and systemic chemotherapy treatments before definitive cytoreduction may facilitate the feasibility and improve the outcome of this therapy to achieve long-term survival. Optimal cytoreduction achieves the best outcomes. © 2012 by American Society of Clinical Oncology. Source

We report on the case of a 41-year-old man with a recently diagnosed amelanotic ulcerated melanoma, with a Breslow thickness of 3.5mm and Clark level IV. He had a pre-existing mass in the axilla, which had grown in parallel to the developing tumor. A large regional lymph node was clinically suspected. Ultrasound (US) examination of the axilla showed a large benign lipoma but also a very atypical peripheral perfusion. At the same time, a sentinel node showed a peripheral perfusion on US. Fine-needle aspiration cytology was performed of the different lesions and showed a melanoma metastasis in the sentinel node. There after, a lymph node dissection was performed. The lipoma was seen in histopathology and even the peripheral perfusion was confirmed. US and US-guided fine-needle aspiration cytology can be easily applied in the diagnosis of lymph node metastases in melanoma patients and can help determine a benign or a malignant involvement. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

The aim of this study was to evaluate air and surface contaminations, and internal contamination of healthcare workers during open-abdomen HIPEC using oxaliplatin. Platinum (Pt) was measured in urine of exposed workers and in multiple air and surface samples. Three successive HIPEC procedures were investigated in each of the two hospitals participating in the study. Analysis of air samples did not detect any oxaliplatin contamination. Heavy contamination of the operating table, the foor at the surgeon’s feet, and the surgeon’s overshoes were observed. Hand contamination was observed in surgeons using double gloves for intra-abdominal chemotherapy administration, but not in those using three sets of gloves. Pt was not detected in urine samples obtained after HIPEC (<5 ng/L). The main risk of HIPEC is related to direct or indirect skin exposure and can be prevented by correct use of adapted protective equipment. © 2015 National Institute of Occupational Safety and Health.

Background Abdominoperineal resections (APR) for anorectal tumors are associated with a high rate of perineal wound complications. The aim of this study was to evaluate the impact of pseudocontinent perineal colostomy (PPC) following APR on perineal wound healing. Methods All patients undergoing APR between 2000 and 2009 were retrospectively reviewed. Perineal wound healing was compared between patients with PPC and those with perineal closure alone. Results APR was performed in 132 patients, including 31 with PPC and 101 with no PPC. Risk factors such as radiotherapy, smoking, diabetes mellitus, and obesity were not different between the two groups. The PPC group had significantly fewer cases of omentoplasty and adenocarcinoma histology. The overall perineal complication rate, perineal infection, or wound dehiscence was similar in the two groups, but the perineal healing rate at 6 and 12 weeks was significantly increased in the PPC group than in the non-PPC group (70.9% vs. 50%, P=0.04, at 6 weeks; 90.3% vs. 73%, P=0.04, at 12 weeks). Conclusions PPC accelerates perineal wound healing after APR without decreasing the overall perineal complication rate. Copyright © 2011 Wiley Periodicals, Inc. Source
