Surgical resection is the treatment of choice in patients with colorectal liver metastases, with 5-year survival rates reported in the range of 40%-58%. Over the past 10 years, there has been an impetus to expand the criteria for defining resectability for patients with colorectal metastases. In the past, such features as the number of metastases (three to four), the size of the tumor lesion, a...

BACKGROUND The treatment of neuroblastoma is dependent on exquisite staging; is performed postoperatively and is dependent on the surgeon's expertise. The use of risk factors through imaging on diagnosis appears as predictive of resectability, complications and homogeneity in staging. AIM To evaluate the traditional resectability criteria with the risk factors for resectability, through the r...

BACKGROUND The only curative treatment for gastric cancer is its surgical excision associated to a lymph node dissection. AIM To study the evolution of resectability and operative mortality of total and subtotal gastrectomy for gastric cancer, in a period of 35 years. MATERIAL AND METHODS Review of medical records of 3000 patients with gastric cancer, operated between 1969 and 2004. Resecta...

Complete tumor resection is still the only potentially curative therapy option for patients with ductal adenocarcinoma of the pancreas. Surgical exploration is the gold standard for the determination of tumor resectability. Radiological resectability assessment is of great importance because many clearly unresectable cases can be identified preoperatively and it became essential for surgical pl...

BACKGROUND Prediction of postoperative survival for hilar cholangiocarcinoma (HCCA) remains difficult although there have been a variety of clinical classification and staging systems. This study was designed to validate and compare some of the major HCCA staging systems in use today. In addition, we sought to build up a new staging system modified from Jarnagin-Blumgart (J-B) classification fo...

Staging classification in patients with non-small cell lung cancer does not always correlate perfectly with surgical resectability. Therefore, it is important to evaluate individual features of a patient's tumor in order to determine if surgical resection is the optimal method of treatment, regardless of tumor stage. Such features include characteristics of the primary tumor, regional lymph nod...

UNLABELLED Patients with pancreatic cancer continue to have a poor prognosis, with a 5-y survival rate of less than 5%. Surgery is the only treatment that offers a potential cure. Determining resectability is the principal goal of staging in pancreatic cancer patients. Our objective was to evaluate the value of combined contrast-enhanced (18)F-FDG PET/CT in assessing the resectability of pancre...
