Head and neck cancers are considered to be the most common cancers in developing countries, especially in Southeast Asia. In India, it accounts for one-fourth of male cancers and one-tenth of female cancers. An attempt was made to study head and neck cancer trends in the Dibrugarh district of Assam, North-East India, India. All sites viz., oral cavity and mobile tongue, oropharynx, hypopharynx, larynx, nasopharynx and others were considered separately for both the sexes to carry out the present analysis. Using the data from the Population-Based Cancer Registry, Upper Assam, Dibrugarh, annual crude incidence rate and age-specific rate were calculated for the period from 2003 to 2016. Mann-Kendall and Sen's Slope non-parametric analysis were applied to examine the trend in the percentages of Head and Neck cancers. The most frequent incidence site for HN cancers was the hypopharynx (33.50%). The disease was common among the males (78.87%) compared to the female (21.13%) population in Dibrugarh district. HN cancers are more prone to the age group 50-70 years (60.93%) compared to the individuals with less than 50 years (26.51%). Combining all the sites of HN cancers in male showed a significant decrease in incidence, whereas in female increasing trend was noted over a period of time. A slight decline in the percentage of head and neck cancer was documented in Dibrugarh when we combined both sexes. The results obtained from the current investigation will laid the scientific framework for proper planning and organization of prevention, diagnosis and treatment of HN cancers in Dibrugarh district, Assam.
头颈癌被认为是发展中国家最常见的癌症，尤其是在东南亚。在印度，它占男性癌症的四分之一和女性癌症的十分之一。本研究试图分析印度东北部阿萨姆邦迪布鲁格尔地区的头颈癌发病趋势。本次分析分别考虑了所有部位，即口腔和活动舌、口咽、下咽、喉、鼻咽等部位的男性和女性发病情况。利用基于人群的上阿萨姆邦迪布鲁格尔癌症登记处的数据，计算了2003年至2016年期间的年粗发病率和年龄别发病率。采用曼-肯德尔和森斜率非参数分析来检验头颈癌百分比的趋势。头颈癌最常见的发病部位是下咽（33.50%）。在迪布鲁格尔地区，该疾病在男性中更为常见（78.87%），而女性中发病率为21.13%。与50岁以下的人群（26.51%）相比，头颈癌更容易发生在50 - 70岁的年龄组（60.93%）。综合男性头颈癌的所有发病部位，发病率呈显著下降趋势，而女性则呈上升趋势。当我们将男女数据合并时，迪布鲁格尔地区的头颈癌百分比略有下降。本次调查结果将为阿萨姆邦迪布鲁格尔地区头颈癌的预防、诊断和治疗的合理规划与组织奠定科学框架。
