Malignant tumours of the digestive tract. A twenty five year study.

A twenty five year retrospective study of malignant tumours was carried out. Malignant digestive tract tumours were about 10% of the total. Segment distribution of the lesion showed highest incidence in large intestine (43.3 percent), oroparynx (34.5 percent), stomach (11.3 percent), oesophagus (6.5 percent) and small intestine (4.4 percent). The maximum cases (74.2 percent) were between 31-60 years, the youngest being a two month old female with rhabdomyosarcoma orpharynx and the oldest a 82 year old male with squamous cell carcinoma anal canal.
