An oral leukoplakia register was established among 50,000 villagers in five districts of India in 1967-68. The paper describes the results after a 5-year follow-up study among 30,000 subjects from three of the districts with regard to spontaneous regression of leukoplakias. The follow-up rate for the three districts varied from 66.6 % to 794 %. The corresponding rates for individuals with leukoplakias varied from 67.6 % to 759 %. The regression, comprising a total or partial disappearance, varied from 26.1 % to 437 % in the three districts. The upper labial mucosa, the left commissure and left buccal mucosa were the sites of maximum regression. In Ernakulam, leukoplakias appeared to regress more often among chewers than among smokers. Although 23.2 % of the patients with regressed leukoplakias had changed their chewing or smoking habits, none had stopped either chewing or smoking. [ABSTRACT FROM AUTHOR]

In three districts of India where an oral precancer registry comprising 30,000 individuals was established in 1967, regular follow-up surveys have been conducted. This paper discusses the results of a 7-year follow-up study. In Bhavnagar district only one case of oral cancer was reported in this study. In the districts of Ernakulam and Srikakulam, age-adjusted annual incidence rates for oral cancer were found to be 33 and 22 per 100,000 respectively. The significance of tobacco habits and oral submucous fibrosis as etiologic factors is discussed. [ABSTRACT FROM AUTHOR]
