ObjectiveWe performed this prospective screening trial in chronic hepatitis virus-infected patients to determine the incidence of hepatocellular cancer (HCC) and the resectability and longterm survival rates of these HCC patients. Summary Background Data

Angiosarcoma of the breast is one of the rarest malignancies. Breast angiosarcoma can be classified into primary when arising de novo and secondary to chronic lymphoedema or breast irradiation. Molecular pathways involved in angiosarcoma development have not been described clearly, yet some gene point mutations and protein altered expression levels have been detected. So far, their management is based above all on surgery. Hence, further studies starting from the few known key points may help to develop more effective strategies based both on target therapies, together with surgery.

Surgical treatment of distal rectal cancer has long been based only on abdominoperineal excision, resulting in a permanent stoma and not always offering a definitive local control. Sphincter saving surgery has emerged in the last 20 years and can be offered also to patients with low lying tumours, provided that the external sphincter is not involved by the disease. An intersphincteric resection (ISR) is based on the resection of the rectum with a distal dissection proceeding into the space between the internal and the external anal sphincter. Originally described as an open procedure, it has also been developed with the laparoscopic approach, and also this technically demanding procedure is inscribed among those offered to the patient by a minimally invasive surgery. Indications have to be strict and patient selection is crucial to obtain both oncological and functional optimal results. The level of distal dissection and the extent of internal sphincter resected are chosen according to the distal margin of the tumour and is based on MRI findings: accurate imaging is therefore mandatory to better define the surgical approach. We here present our actual indications for ISR, results in terms of operative time, median hospital stay for ISR in our experience and review the updated literature.
