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.

Chordoma of the mobile spine and sacrum: a retrospective analysis of a series of patients surgically treated at two referral centers.
Chordoma is a rare tumor, and its natural history is still not well known. ⋯ Tumor size and surgical margins affected outcome only on initial presentation. However, wide surgery was feasible in a minority of cases. Most patients died of local-regional disease even when metastases occurred. Indeed, long-term prognosis was such that disease-free survival at 10 years was only 26%.

Perioperative hyperfractionated high-dose rate brachytherapy for the treatment of soft tissue sarcomas: multicentric experience.
Low-dose rate brachytherapy is a well-established adjuvant treatment for soft tissue sarcomas (STS). The experience with high-dose rate brachytherapy (HDR BT) in this indication is limited. The purpose of our study was to evaluate the viability of perioperative hyperfractionated HDR BT for STS. ⋯ Our study suggests that perioperative HDR BT is a promising method for achieving high biological doses with good LC in the postoperative radiotherapy of STS and that combination of BT and EBRT provides better tumor control than BT alone.

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.
