Patterns of cancer occurrence in different regions of West Bengal--a hospital based study.

The incidence of cancer has been rising steadily in the third world countries including India. The patterns of cancer incidence reflect the racial, cultural and pharmacogenomic diversity within populations and nowhere is this diversity more striking than in the Indian subcontinent. This article shows the diversity in patterns of incidence of major cancers across three medical college hospitals in the state of West Bengal in India. All the data were collected from the period between 2001 and 2005. The results show a striking variation of incidence of major cancers in the urban, semi-urban and rural parts of the same state. Indeed the differences of the patterns are explainable by the cultural and socioeconomic differences within the populations from which the study samples are drawn. This constitutes the largest single hospital based data collected from this part of the world till date and will help in re-evaluation of cancer control programmes promulgated by the health authorities of the region.

The effect of honey on mucositis induced by chemoradiation in head and neck cancer.

The aim of this study was to evaluate the effect of pure natural honey on radiation-induced mucositis. Fifty-five patients diagnosed with head and neck cancer requiring radiation to the oropharyngeal mucosal area were divided into two groups (study arm-28 and control arm-27) to receive either chemoradiation or chemoradiation plus topical application of honey. Patients were treated using a telecobalt machine at 2 Gy per day, five times a week up to a total dose of 66 Gy. in the study arm, patients were advised to take 20 ml of honey 15 minutes before, 15 minutes after and similar amount at bed time. Patients were evaluated every week for the development of radiation mucositis using the WHO grading system. There was significant reduction in the symptomatic grades 3 and 4 mucositis in honey-treated patients compared to controls ie, 18% versus 41% for grade 3 and 4% versus 22% for grade 4 mucositis. Seventy-one per cent of patients treated with topical honey showed no change or a positive gain in body weight. In the control group also 22% had no weight loss, though none showed weight gain. Furthermore, it didn't affect blood sugar level when initial fasting blood sugar level was < 150 mg%. Honey is a cheap, simple, easily available and effective agent in reducing radiation-induced mucositis. Within the limits of this study the results showed the application of natural honey is effective in managing radiation induced mucositis, which warrants further multicentric randomised trials to validate the findings.
