Abstract

Shafi Ahmed1, Noorudheen N. K2

Oesophageal malignancies are not an uncommon disease entity in this part of India. It is observed in both the sexes. Patients present with progressive dysphagia for solids. The duration of symptoms varies from 6 months to 2 years. Among the various aetiological factors, smoking, alcohol intake, spicy hot food intake, industrial pollution and achalasia cardia are a few worth mentioning.
AIM OF THE STUDY
To evaluate the differences in the predisposing factors causing squamous cell carcinoma and adenocarcinoma of oesophagus in this part of India.
MATERIALS AND METHODS
The study is conducted in the Department of Surgery at Government Medical College Hospital, Kozhikode; Kerala. One hundred patients attending the Department with history of Dysphagia were included after thorough history taking, clinical and endoscopic examination and found to have malignant growths in the oesophagus which was confirmed by biopsy and histopathological examination. Various aetiological factors were elicited and analysed in both the histological varieties of malignancy of oesophagus.
OBSERVATIONS AND RESULTS
Significant number of patients with history of paan chewing presented with histological picture of squamous cell carcinoma as compared to patients who had adenocarcinoma. Gastroesophageal reflux disease was more commonly associated with adenocarcinoma. Out of 37 patients with adenocarcinoma, 31 patients had history of gastroesophageal reflux disease (83.8%). 6 patients had no history of gastroesophageal reflux disease (16.2%) within histology. Consumption of hot drinks, tea and coffee more than 10 per day has been analysed. 52 were consuming, 48 were not consuming, P value 0.179 non-significant.
CONCLUSIONS
Squamous cell carcinoma is more prevalent as compared to adenocarcinoma in present study. The main factor that has emerged is lifestyle, dietary habit, smoking and alcohol, and environmental factor. Consumption of alcohol and smoking is known risk factors in carcinoma oesophagus, but present study shows no significance as more number of females are present in this study. Females rarely consume alcohol in this part of the country, but among alcoholics/smokers, majority have squamous cell carcinoma which is significant. Habit of paan chewing is more common among females.
