Comparative study of efficacy and toxicities of cisplatin vs vinorelbine as radiosensitisers in locally advanced head and neck cancer

Introduction:

Currently, concomitant chemoradiation using cisplatin is one of the standards of care for the management of head and neck cancer, but at the cost of increased acute toxicity. Our aim was to assess whether vinorelbine was less toxic and of at least comparable efficacy, if not better, compared with cisplatin.

Materials and methods:

A total of 72 patients with squamous cell carcinoma in the head and neck region were recruited, 40 in arm A and 32 in arm B. Patients in arm A received 40 mg/m2 cisplatin weekly. Patients in arm B received 6 mg/m2 vinorelbine weekly. Both arms also received 66 Gy of radiation in conventional fractionation.

Results and analysis:

There was no statistically significant difference in response rate or toxicities between the two arms, except for nausea and/or vomiting, which was significantly less frequent in the vinorelbine arm.

Conclusion:

Vinorelbine was as effective as cisplatin in controlling locoregional disease in locally advanced head and neck cancer, but was only marginally less toxic than cisplatin.

Evaluation of results of radiotherapy alone vs combined surgery and postoperative radiotherapy in carcinoma external auditory canal-10 years review

Forty-one patients of external auditory canal (EAC) cancer attended the Department of Radiotherapy (RT), Medical College Hospital, Kolkata during the period from 1987 to 1996. Majority were above 50 years of age with slight female preponderance. Out of 41 patients 36 patients completed the full course of treatment of which 12 patients underwent combined modality treatment (RT 50-55 Gy plus surgery) and 24 patients received primary RT alone (55-60 Gy). Radiation therapy was given in standard fractionation schedule. Retrospective analysis revealed complete response in 8/12 (66.7%) in combined modality treatment group and in 3/24 (12.5%) in RT alone group. The actuarial 2 year survival was 19%. following RT alone, 85% following combined modality, 70% in early lesions and 18% in advanced lesions. The study suggests, surgical resection followed by postoperative irradiation is an effective method and better treatment option than RT alone as primary treatment modality for carcinoma of EAC.
