BACKGROUND The extent of regional lymph node (LN) metastasis is the most important factor in the evaluation of resectability and prognosis of non-small cell lung cancer (NSCLC) to increase the chance of complete cure. The authors attempted to deduce a group of genes from the analysis of mRNA expression profiles of the tumor tissues of NSCLC patients with or without LN metastasis, and make a cla...
INTRODUCTION To evaluate efficacy and secondary resectability in patients with locally advanced pancreatic cancer (LAPC) treated with neoadjuvant chemoradiotherapy (CRT). PATIENTS AND METHODS A total of 215 patients with locally advanced pancreatic cancer were treated with chemoradiation at a single institution. Radiotherapy was delivered with a median dose of 52.2 Gy in single fractions of 1...
INTRODUCTION Portal vein embolization (PVE) may increase the resectability of liver metastases. However, the problem of PVE is insufficient growth of the liver or tumor progression in some patients. The aim of this study was to evaluate the significance of commonly available clinical factors for the result of PVE. MATERIAL AND METHODS Portal vein embolization was performed in 38 patients with...
Liver resection can provide long-term survival and cure for patients with colorectal liver metastases but is feasible in only 15-25% of patients. In the last few years several major developments have contributed to increase this resectability rate. Neo-adjuvant chemotherapy can provide response rates as high as 50%, allowing surgery in about 10-15% of patients initially deemed unresectable. Pat...
Ventilation and perfusion lung scans were performed in 58 patients before operation for bronchial carcinoma to determine in which patients the lung scan was most useful for assessing mediastinal spread and resectability of the tumour. Perfusion of the affected lung was less with larger and more centrally situated tumours. Perfusion was also less for left-sided than for right-sided tumours but t...
Although notable progress in diagnosis and therapy has been made in recent years, the 5-year survival of patients diagnosed with ductal adenocarcinoma of the pancreas is still less than 5% [1]. To date, surgery is the only curative option for patients suffering from this aggressive entity. Nowadays in high-volume centers, this procedure can be performed with a mortality of 1–3% and morbidity of...
Colorectal cancer is a worldwide public health problem. More than 20% of patients with colorectal cancer present at an advanced stage, and the liver is the most common site of metastases. More recently, selection criteria for resectability have been expanded, but definition of resectability still remains challenging. Since the presence of metastases is the most relevant prognostic factor, surgi...
