Epidemiological trends of cancer morbidity at a government medical college hospital, Chandigarh, India.

AIM: An epidemiological shift has resulted in increase in the prevalence of non-communicable diseases (NCD). Unlike other NCDs which are easily and definitely preventable, the knowledge of cancer prevention is still limited at present. Various aetiological factors are difficult to control since those are habit forming. Hence an available remedy remains its secondary and tertiary prevention for which appropriate planning is of paramount importance. Evidence based planning requires careful analysis of data with a view to prioritize various cancers. Keeping in view the fact that the adaptation of smoking free status in Chandigarh city might have a far reaching positive effect on the cancer related morbidity of the people, the following study was undertaken to provide base line data to be used for future comparisons. METHODS: The registers maintained in the Department of Radiotherapy were checked and those belonging to the years 1999 to 2009 were utilized to analyze the cancer morbidity in respect to age, sex, and year of presentation to health care facility. RESULTS: A total of 4,600 cancer patients (males=2276, females=2324) demonstrated a gradual increase in the number of cancer cases from 150 in the year 1999 to 783 in the year 2009. The most common cancers amongst males were cancer of gastro-intestinal tract (GIT) and lung (including larynx) constituting 37.3% and 27.1% of the total, respectively. In females these were cancers of breast and cervix representing 33.3% and 17.6% of total cancer cases, respectively, and lung cancer constituted 5.3%. The maximum cases of bone cancer (53.8% of all bone cancers) were observed amongst children aged less than 20 years and lung cancer (48.2% of all lung cancers) among the elderly aged 60-69 years.

Epidemiological study of risk factors for oral, laryngeal and esophageal cancers at a tertiary care hospital in India.

UNLABELLED: BACKGROUND AND AIS: An epidemiological shift in the form of increase in the incidence of cancer and decrease in the incidence of smoking is universally realized today. This study was conducted to observe an association of smoking, use of alcohol and tobacco and cancers of the oral cavity, larynx and esophagus MATERIAL AND METHODS: it was a case control study conducted at Deptt. of Radiotherapy at GMCH, Chandigarh. The registers from radiology department were utilized and studied for the presence of history of alcohol consumption, smoking and tobacco intake. Statistical analysis was done by calculating Odds ratio along with 95% confidence interval. RESULTS: Out of 363 cases with the diagnosis of Laryngeal, Esophageal and Oral Cancer along with 568 controls studied, 42 (11.6%) were in the age group of 30-44 years, 153 (42.1%) in the age group of 45-59 years and rest 171 (47.1%) in the age group of 60+ years. Among cases, the percentage of tobacco use, smoking and alcohol consumption was 10.5, 60.6 and 33.6 respectively as against the similar percentages among controls 1.4, 9.0 and 6.3. The odds ratio for tobacco use in relation to patients aged 60+ years was 2.39, in the age group of 45-59 years was 11.19 and increased to 55.35 in the age group 30-44 years. Similarly the overall odds ratio for alcohol consumption was 7.48 and it was 4.98 in the age group 60+ years, 6.30 in the age group 45-59 years and increasing to 17.00 in the age group of 30-44 years. CONCLUSION: Finding suggests that risk of cancer of the upper respiratory and alimentary tracts is higher with tobacco and alcohol use. Further studies are required.
