ReviewAdvanced head and neck cancer and clinical experience of an effective new agent: docetaxel.
Docetaxel is a taxoid cytotoxic agent known to have considerable clinical activity in a broad range of malignancies. A series of phase I/II studies have been performed to elucidate its toxicity and antitumor activity in advanced squamous cell carcinoma of the head and neck. DOCETAXEL AS FIRST-LINE MONOTHERAPY: Docetaxel administered at 100 mg/m2 as a 1-hour infusion every 3-4 weeks initiated an overall response of 27-42% for a duration of 5-6.5 months in patients with recurrent locoregional or metastatic disease. These results compare favourably with other single-agents in this setting. ⋯ Docetaxel appears to have substantial antitumour activity in advanced head and neck cancer and further studies are justified to determine its full role in the management of this disease.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative adjuvant chemotherapy with 1-hexylcarbamoyl-5-fluorouracil in patients with colorectal cancer and at a high risk for recurrence.
We examined the effects of postoperative 5-fluorouracil (5-FU) infusions and oral treatment with 1-hexylcarbamoyl-5-fluorouracil (HCFU) on patients curatively resected for stages II-IV colorectal cancer. The study was prospectively randomized, and 251 (93.3%) of 269 patients were valid candidates for statistical assessment. The inductive regimen for group A included 5-FU 10 mg intravenous (i.v.) injections on days 0, 1, 2, 7, 8 and 9, postoperatively. ⋯ There was no statistical difference in survival time between the groups for 251 eligible cases (p = 0.079). In group A given 5-FU plus HCFU, there was a reduction in the recurrence rate for patients with stages III-IV or lymph node metastasis-positive colorectal cancers (p < 0.05) and prolongation of the survival time for patients with stage III-IV, transmural invasion-positive or lymph node-positive colorectal cancers (p < 0.05). Our findings show that the combination of 5-FU infusion and the continuous administration of HCFU is effective in treating patients with surgically resected colorectal cancer who are at high risk for a recurrence.

Beneficial effects of a vanadium complex with cysteine, administered at low doses on benzo(alpha)pyrene-induced leiomyosarcomas in Wistar rats.
Vanadium is a potent environmental and body metal, possessing remarkable antitumor and antidiabetic properties. Vanadium salts and complexes have been widely investigated for their anticarcinogenic properties in experimental carcinogenesis. In the present study the antitumor effects of a new vanadium complex with cysteine in relation to identical doses of vanadyl sulfate and cysteine, in tumor bearing rats are investigated. ⋯ Vanadyl sulfate, cysteine and V(III)-cysteine complex exerted antitumor effects in tumor bearing rats. The V(III)-cysteine complex, however, exerts much more potent effects, as evident from the results of the present study. These beneficial effects of the above complex, in combination with its low toxicity provide evidence suggest its possible application in the treatment of human malignant diseases.

The recent meeting of the AGMIF (Working Group for Mistletoe Therapy and Immunological Research) held in Herdecke, Germany, on October, 3rd, 1997, covered recent developments in the field of immunological and biological properties of Viscum album L., the European mistletoe, which is used for adjuvant cancer treatment. So far, one extract component, the mistletoe lectin (ML)-1, was propagated by some researchers to be the only relevant substance within the extracts. ⋯ In the second part, clinical evidence for the beneficial effects of subcutaneous and intratumoral application of mistletoe therapy was presented by different working groups. However, further research is of great importance to carefully analyse and characterize the involved molecules and exact mechanisms underlying the beneficial effects reported in this meeting.

Randomized Controlled Trial Comparative Study Clinical TrialComparative crossover trial of two intravenous doses of granisetron (1 mg vs 3 mg) + dexamethasone in the prevention of acute cis-platinum-induced emesis.
The 5HT3 receptor antagonist Granisetron (GRA) is available on the market as a 1 mg vial in USA and as a 3 mg vial in Europe. This study aimed to compare the two i.v. doses of GRA (3 mg vs 1 mg), both of which combined with Dexamethasone (DEX) (20 mg) in the prevention of acute Cisplatinum (CP)-induced emesis. ⋯ This study shows that, under the above conditions, the 1 mg and 3 mg i.v. GRA doses are comparably effective when combined with DEX 20 mg in the prevention of acute CP-induced emesis.
