Expression of surface protein receptors in lung cancer.

Cell adhesion is a basic count in inter- and intracellular communication and plays an important role in tumor progression. In this study, the expression of E-selectin, ICAM-1 and VCAM-1 were evaluated by means of immunohistochemistry in a group of 153 lung cancer specimens. E-selectin immunoreactivity was localized mostly on endothelial cell venules and capillaries with an average staining intensity of 75% of cells in the NSCLC, while in SCLC the intensity of the staining was 69%.

Tolerability of Raltitrexed ('Tomudex') in elderly patients with colorectal cancer.

Purpose: Colorectal cancer (CRC) is one of the major health problems of the Western world and the proportion of elderly patients with CRC is growing. Raltitrexed ('Tomudex'), a specific thymidylate synthase inhibitor, has shown efficacy and manageable toxicity in elderly CRC patients. In this retrospective study, the tolerability of raltitrexed in patients with CRC was examined in relation to age.

Gemcitabine as single agent chemotherapy in elderly patients with stages III-IV non-small cell lung cancer (NSCLC): a phase II study.

Introduction: In the past the unfavourable profile of toxicity of antineoplastic drugs employed (i.e. cisplatinum) weakened the role of chemotherapy in aged patients with non-small cell lung cancer (NSCLC).
