Antiemetic therapy.

The emetogenic potential of cancer chemotherapeutic agents varies according to the agent employed. Among the highly emetogenic agents, cisplatin has been the most studied. As for emesis induced by cisplatin, an optimal antiemetic schedule is effective in 70-90% of cases of acute emesis, in 60% of cases of delayed emesis, whereas acute emesis induced by moderately emetogenic agents can be prevented in over 90% of cases. The major risk factor in delayed emesis is the vomiting experienced during the previous chemotherapy cycles. Special situations are represented by high-dose chemotherapy and radiation therapy. Drugs and scheduling for emesis prevention in children are empirically derived from the regimens employed for adults, although some differences in the pharmacokinetics and in toxicity profiles have been reported.

Forecasting the performance status of head and neck cancer patient treatment by an interval arithmetic pruned perceptron.

The integration of chemotherapy and radiotherapy for the treatment of advanced head and neck cancer is still a matter of clinical investigation. An important limitation is that the concomitant administration of chemotherapy and radiotherapy still induces severe toxicity. In this paper, a simple artificial neural network is used to predict, on the basis of biological and clinical data, if the cumulative toxicity of the combined chemo-radiation treatment itself would be tolerated. The resulting method, tested on clinical data from a phase II trial, proved to be able to forecast which patients will tolerate a combined chemo-radiotherapeutic approach. This result should open a new perspective in the clinical approach, by supplying a potential predictive indicator for toxicity.

Regionally advanced nasopharyngeal carcinoma: long-term outcome after sequential chemotherapy and radiotherapy.

AIMS AND BACKGROUND: To evaluate the long-term clinical outcome of 61 patients with regionally advanced nasopharyngeal carcinoma treated with sequential chemotherapy and radiotherapy within a phase II trial. METHODS: The trial evaluated a combined modality regimen including 3 cycles of induction polychemotherapy (epirubicin 70 mg/m2 d1, and cisplatin 100 mg/m2 d1, both recycled every 3 weeks) followed by definitive radiotherapy to the primary site (64-70 Gy) and the neck (50-70 Gy). Patients included in the trial had pathologically confirmed nasopharyngeal carcinoma; stage (UICC 1987) T-any, N2-3, M0; ECOG performance status 0-1. Sixty-one patients were enrolled between 1990 and 1996; stage according to UICC 1997 was IIb in 8%, III in 36% and IV in 56% of the patients; histology was WHO type 1-2 in 11% and WHO type 3 in 89% of cases. Minimum follow-up of 33 surviving patients is 5.2 years. RESULTS: Clinical failure has been observed in 30 patients (49%): initial failure, observed within the third year of follow-up in all but one case, was local alone in 6 (20%), regional alone in 10 (33%), local and regional in 1 (3%), regional and distant in 1 (3%), and distant alone in 12 patients (40%). Seven patients received salvage surgery to the neck, 2 of them still disease-free at 10 and 11 years from salvage surgery; 4 patients with an isolated local relapse were re-irradiated, and one of them was alive and well at 6.5 years from salvage radiation. At 5-year local control, regional control and distant metastasis-free rates were 83%, 74% and 73%, respectively; overall and disease-free survival were 64% and 51%. Late effects of initial treatment, as evaluated in 30 patients surviving 5 years without relapse, were generally acceptable, but some degree of xerostomia, dental damage, trismus and hearing loss were reported by a significant proportion of patients (respectively 100%, 88%, 76% and 86%). CONCLUSIONS: In our experience, long-term clinical cure of regionally advanced nasopharyngeal carcinoma was obtained in 51% of cases treated with chemotherapy and radiotherapy. Salvage treatments (neck surgery, local re-irradiation) are worthy, as they increase the cure rate by approximately 10%, raising 5-year survival to over 60%. Late effects are significant, calling for refinements in radiation technique, better integration with chemotherapy to possibly decrease the need for higher radiation dose, and/or use of effective radioprotectants.
