Tandon, S. Bahadur, G. Rath, B. Mohanti] As head and neck cancer patients are beginning to survive longer, the problem of second primaries is rapidly gaining significance. The incidence of this problem in India is hitherto unknown. Of 900 patients with squamous all carcinoma in the head and neck undergoing curative therapy during a nine year period, 23 (2.55 per cent) developed a second primary after a mean interval of 26.7 months. Twenty- one second tumours were metachronous while only two were synchronous. Eighteen of the 23 second primaries were detected within three years of diagnosis of the index primary. The oropharynx was the most common location of second primaries. Only three patients could be surgically salvaged. Association of Otolaryngologists of India, 1996 Tandon D.
