To determine the maximum-tolerated dose (MTD) and dose-limiting toxicity (DLT) of both docetaxel and 5-fluorouracil (5-FU) when administered weekly in a regimen of docetaxel, 5-FU/leucovorin and cisplatin (DFLP) for 2 consecutive weeks every 3 weeks. ⋯ Two consecutive weeks of DFLP infusions every 3 weeks appear to be an active regimen with a tolerable toxicity profile in advanced gastric cancer. For further phase II studies, the recommended dose for this combination is 40 mg/m2 of docetaxel and 2,000 mg/m2 of 5-FU per week.

Comparative Study Clinical Trial
Combined irinotecan, oxaliplatin and 5-fluorouracil in patients with advanced colorectal cancer. a feasibility pilot study.
To evaluate the feasibility and a possible activity range of combination irinotecan (CPT-11), oxaliplatin, and 5-FU in advanced colorectal cancer (ACC). ⋯ This combination seems to have substantial activity in ACC. Overall toxicity was unacceptable in the IA-FU and IRI300 groups, with diarrhea and cytopenia constituting the dose-limiting side effects. Tolerance and efficacy profiles achieved with IV oxaliplatin (120 mg/m2 day 1), IV CPT-11 (250 mg/m2 day 1) and IV 5-FU 2.6 g/m2 with IV leucovorin (500 mg/m2 days 1 and 15) was favorable and deserves further investigation.

Approximately 25,000 patients have been treated to date with the humanized anti-HER2 monoclonal antibody, Herceptin. This therapy has proved effective and well tolerated in patients with HER2-positive metastatic breast cancer; adverse events were generally infusion-related fever and chills of mild-to-moderate severity. Cardiotoxicity and infusion-related reactions emerged as the two main safety concerns with the use of Herceptin. ⋯ The majority occurred during or shortly after the first infusion and were characterized by respiratory symptoms. Most patients were successfully treated; a total of 33 patients continued Herceptin therapy with no recurrence of infusion reactions. Although the benefit to risk ratio of Herceptin remains favorable, physicians must be vigilant and aggressive in managing cardiotoxicity and infusion-related reactions.

The Brief Pain Inventory (BPI) is a pain assessment tool. It has been translated into and validated in several languages. The purpose of this study was the translation into and validation of the BPI in Greek. Moreover, we wanted to detect cultural and social differences, if any, of pain interference in patients' lives. ⋯ This study shows the efficacy of the G-BPI for the assessment of pain severity as well as the pain management in Greece, and therefore its utility in improving the analgesic treatment outcome in Greek patients.

The identification of tumor-associated antigens recognized by cellular or humoral effectors of the immune system has opened new perspectives for cancer immunotherapy. Different categories of cancer-associated antigens have been described as targets for CD8+ T cells in vitro and in vivo: (1) 'cancer-testis' (CT) antigens expressed in different tumors and normal testis; (2) melanocyte differentiation antigens; (3) point mutations of normal genes; (4) antigens that are overexpressed in malignant tissues, and (5) viral antigens. Clinical trials with antigenic peptides have been initiated to induce specific immunological responses in vivo. ⋯ Recently, a strategy utilizing spontaneous antibody responses to tumor-associated antigens (SEREX) has led to the identification of a new CT antigen, NY-ESO-1. NY-ESO-1-specific spontaneous humoral and cellular immune responses were found in approximately 50% of patients with NY-ESO-1-positive tumors. Clinical studies have been initiated to evaluate the immunological effects of immunization with NY-ESO-1 peptides in cancer patients with detectable or absent immunity against NY-ESO-1.
