Epigenetics in non-small cell lung carcinomas

Role of metallothionein expression in non-small cell lung carcinomas.

Metallothionein (MT) is a low molecular weight protein, which participates in differentiation and proliferation of normal and tumour cells. In some malignant tumours (mammary, renal, ovarian cancers), its increased expression is thought to represent an unfavourable prognostic factor. Non-small-cellular lung cancers (mainly squamocellular cancer and adenocarcinoma) are characterised by ill-defin...

Molecular Pathogenesis of Non-Small Cell Lung Carcinomas

Non-small cell lung carcinoma (NSCLC) from histological and biological perspectives is a complex neoplasm. The sequential preneoplastic changes have been defined for centrally arising squamous cell carcinomas (SCCs) of the lung, and they are less documented for peripherally arising adenocarcinomas. The main morphologic forms of preneoplastic lesions recognized in the lung are squamous dysplasia...

Molecular and Genetic Pathogenesis of Lung Cancer: Differences Between Small-Cell and Non-Small-Cell Carcinomas

Lung cancer is classified into small-cell carcinoma (SCLC) and non-small-cell carcinoma (NSCLC). The profile of molecular and genetic alterations considerably differs between SCLC and NSCLC, as well as among the subtypes of NSCLC. Tp53 is inactivated in nearly 50% of NSCLC, while its mutations with functional inactivation are greatly prevalent in SCLC (70-100%). Rb gene alterations and protein ...

Sentinel Node Mapping in Non-small Cell Lung Cancer Using an Intraoperative Radiotracer Technique

 Objective(s): Lymph node metastases are the most significant prognostic factor in localized non-small cell lung cancer (NSCLC). Identification of the first nodal drainage site (sentinel node) may improve detection of metastatic nodes. Extended surgeries, such as lobectomy or pneumonectomy with lymph node dissection, are among the therapeutic options of higher acceptab...
