The aim of this study was to evaluate the association and the related risk factors between postoperative complications and mortality and the severity of liver cirrhosis in head and neck cancer patients undergoing tumor ablation followed by microsurgical free tissue transfer. ⋯ Child's class, along with its several components, and intraoperative blood transfusion of > or =2 units are predictive factors for morbidity and mortality.

Comparative Study
A comparative study of antiviral therapy after resection of hepatocellular carcinoma in the immune-active phase of hepatitis B virus infection.
The role of antiviral therapy for patients in the immune-active phase of hepatitis B virus (HBV) infection who underwent partial hepatectomy for hepatocellular carcinoma (HCC) is unknown. ⋯ Although nucleoside analogs did not reduce short-term recurrence rate, they promoted postoperative viral clearance and increased residual liver volume, which significantly enhanced tolerance to subsequent therapy for disease recurrence.

Whether laparoscopic gastrectomy affects the number of gastric cancer cells exfoliated from the cancer-invaded serosa remains unclear. This study aimed to compare the detection rate of free gastric cancer cells in the peritoneal cavity during laparoscopic and open gastrectomy. ⋯ The laparoscopic techniques used in gastric cancer surgery did not increase the detection rate of free cancer cells in the peritoneal cavity compared with conventional techniques.

Comparative Study
Sentinel lymph node dissection in primary melanoma reduces subsequent regional lymph node metastasis as well as distant metastasis after nodal involvement.
In many countries sentinel lymph node dissection (SLND) followed by complete lymphadenectomy if positive is routinely performed treatment for primary cutaneous melanoma. However, the potential survival benefit of SLND is still controversial. ⋯ SLND reduced subsequent regional lymph node metastases and improved disease-free survival, while overall survival remained unaffected. SLND reduced distant metastases and improved overall survival in the subgroups of patients with regional lymph node involvement.

Hyperthermic intraperitoneal (IP) chemotherapy after cytoreduction improves survival in patients with colorectal carcinomatosis of the peritoneal surface. Most protocols use single agents (mitomycin C or oxaliplatin) provided IP. The purpose of this study was to determine whether combination IP chemotherapy is superior to single-agent therapy in a mouse model. ⋯ IP therapy with mitomycin C or irinotecan provided a survival benefit compared with intravenous FOLFIRI. Combination IP therapy with mitomycin C, panitumumab, and irinotecan was superior to all other agents tested alone or in combination. This warrants further combination analysis and supports consideration for a phase I application.
