Epidemiology of digestive tract cancers in India IV. Gall bladder and pancreas.
Article in English | IMSEAR | ID: sea-64590
ABSTRACT
Pancreatic cancer is a leading cause of cancer-related deaths in developed countries. Gall bladder cancer is very common in South American countries, around the Mediterranean and in Japan. A majority of patients with these cancers receive only palliative therapy in spite of recent advances in investigation and surgery. Their poor prognosis and increasing incidence in India necessitate a better epidemiologic approach towards their control. This review is based on epidemiological data, publications and abstracts from India. Population-based data reveal that the incidence of gall bladder cancer is very high in northern Indian cities (5-7 per 100,000 women) and low (0-0.7 per 100,000 women) in southern India. The distribution suggests a high-incidence region comprising Uttar Pradesh, Bihar, Orissa, West Bengal and Assam. The cancer is twice more common in women and is the leading cancer among digestive cancers in women in the northern Indian cities of Delhi and Bhopal. There are few analytical data to hypothesize why this geographical predisposition. The high incidence is also observed in north Indian immigrants to the United Kingdom. The incidence of pancreatic cancer is low (0.5-2.4 per 100,000 men and 0.2-1.8 per 100,000 women) in most parts of India. Somewhat higher rates are seen in the male urban populations of western and northern India. Studies from Kerala support an association between tropical pancreatitis and pancreatic cancer. Time trends reveal an increase in the incidence of gall bladder and pancreas cancers; the increase in the former is alarming. We estimate that the approximate annual cancer burden of India in 2001 would include 17,730 cases of gallbladder cancer and 14,230 of pancreatic cancer. Multi-center studies are needed to identify potentially preventable risk factors associated with gall bladder and pancreatic cancer in India.
