Multicenter Study Clinical Trial
High-dose radiotherapy plus prolonged hormone therapy in CT2-3 prostatic carcinoma: is it useful?
Clinical studies published in the last decade have shown the possible improvement in prognosis of patients with prostatic carcinoma undergoing radiation therapy with dose escalation or in combination with hormone therapy. However, in studies on hormone therapy, moderate doses of radiation therapy have been used, whereas in studies with high-dose radiotherapy, hormone therapy usually was not administered. Therefore, it is not clear whether the concomitant use of high doses and prolonged hormone therapy could determine an additional beneficial effect. The aim of the present study was therefore to evaluate the relative prognostic role of different dose levels (< 70 versus > or = 70 Gy) of external beam radiotherapy and of different hormone therapies (neoadjuvant only versus neoadjuvant + adjuvant). ⋯ The results of the study confirmed the positive impact of radiotherapy doses > 70 Gy and of adjuvant hormone therapy in patients with locally advanced prostatic carcinoma. Owing to the lack of evidence of a correlation between radiation dose and biochemical outcome in patients undergoing prolonged hormone therapy, the role of further dose escalation in patients undergoing combined hormone and radiation therapy is still unclear.

To investigate the level of interleukin-6 in advanced non-small cell lung cancer and to analyze the relationship with malnutrition and survival. ⋯ IL-6 secretion may play a role in the pathophysiology of malnutrition in advanced lung cancer. Results show a relation between elevated IL-6 serum levels and malnutrition, poor performance status, acute phase response and shorter survival in patients affected by advanced non-small cell lung cancer.
