Various addiction patterns, dietary habits, associated medical problems, and socioeconomic status in gastrointestinal malignancies: A prospective study in rural area of Maharashtra, India

Background: Gastrointestinal (GI) malignancies are increasing with advancing age. Various addictions and poor dietary habits are among the major risk factors. Early detection is difficult until patient notices symptoms. Primary prevention by knowing various risk factors and early symptom awareness will help in early diagnosis and better treatment outcome. Objectives: This study is carried out to see various addiction patterns, dietary habits, associated medical problems, and socioeconomic status with various sites involved in GI malignancies, at a tertiary care teaching hospital of Western Maharashtra, India. Materials and Methods: Prospective questionnaire-based study was carried out for 11 months. A total of 100 diagnosed carcinoma cases of GI tract malignancy were taken for study. Results and Conclusions: Out of total 100 cases, 61 were male and 39 were female. The most common site involved was esophagus (41) followed by rectosigmoid, colon and cecum, stomach, and anal canal (29, 14, 13, and 3, respectively). There were 45% of cases above 60 years of age. The most common addiction was smokeless tobacco. Most of the patients belonged to lower and upper lower class (64%). Majority of cases (81%) were nonvegetarian, only 16% were pure vegetarian. Most of the cases (85%) were in advanced stage of disease (III and IV). Awareness program for harmful effects of various addictions and importance of high-fiber diet (vegetarian diet) will help in health promotion and prevention of various malignancies. Awareness about the early symptoms of GI malignancy will help in early detection of disease and better treatment outcome.

Radical radiotherapy treatment (EBRT + HDR-ICRT) of carcinoma of the uterine cervix: outcome in patients treated at a rural center in India.

AIM: To report the outcome of carcinoma of the uterine cervix patients treated radically by external beam radiotherapy (EBRT) and high-dose-rate (HDR) intracavitary radiotherapy (ICRT). MATERIALS AND METHODS: Between January 1997 to December 2001, a total of 550 newly diagnosed cases of carcinoma of the uterine cervix were reported in the department. All cases were staged according to the International Federation of Gynecologists and Oncologists (FIGO) staging system, but for analytical convenience, the staging was limited to stages I, II, III, and IV. Out of the 550 cases, 214 completed radical radiotherapy (EBRT + HDR-ICRT) and were retrospectively analyzed for presence of local residual disease, local recurrence, distant metastases, radiation reactions, and disease-free survival. RESULTS: There were 7 (3.27%), 88 (41.1%), 101 (47.1%), and 18 (8.4%) patients in stage I, II, III, and IV, respectively. The median follow-up time for all patients was 43 months (range: 3-93 months) and for patients who were disease free till the last follow-up it was 59 months (range: 24-93 months). The overall treatment time (OTT) ranged from 52 to 73 days (median 61 days). The 5-year disease-free mean survival rate was 58%, 44%, 33%, and 15%, with 95% confidence interval of 48 to 68, 37 to 51, 24 to 35, and 6 to 24 for stages I, II, III, and IV, respectively. There were 62 (28.97%) cases with local residual disease, 35 (16.3%) developed local recurrence/distant metastases, 17 (7.9%) developed distant metastases, and 9 (4.2%) had local recurrence as well. DISCUSSION AND CONCLUSION: The overall outcome was poor in advanced stage disease, but might be improved by increasing the total dose, decreasing overall duration of treatment, and by adding chemotherapy in patients with disease limited to the pelvis.

High-dose-rate-intracavitary brachytherapy applications and the difference in the bladder and rectum doses: a study from rural centre of Maharashatra, India.

AIM: To report the difference in the bladder and rectum doses with different applications by the radiotherapists in the same patient of the carcinoma of the uterine cervix treated by multiple fractions of high-dose-rate (HDR) intracavitary brachytherapy (ICBT). MATERIALS AND METHODS: Between January 2003 to December 2004, a total of 60 cases of the carcinoma uterine cervix were selected randomly for the retrospective analyses. All 60 cases were grouped in six groups according to the treating radiotherapist who did the HDR-ICBT application. Three radiotherapists were considered for this study, named A, B and C. Ten cases for each radiotherapist in whom all three applications were done by the same radiotherapist. And 10 cases for each radiotherapist with shared applications in the same patient (A+B, A+C and B+C). The bladder and rectal doses were calculated in reference to point "A" dose and were limited to 80% of prescribed point "A" dose, as per ICRU-38 recommendations. Received dose grouped in three groups--less then 80% (< 80%), 80-100% and above 100% (>100%). A total of 180 applications for 60 patients were calculated for the above analyses. RESULTS: There is a lot of difference in the bladder and rectal doses with the application by the different radiotherapists, even in the same patient with multiple fractions of HDR-ICBT. Applications by 'A' radiotherapist were within the limits in the self as well as in the shared groups more number of times, by 'B' radiotherapist was more times exceeding the limit and by 'C' radiotherapist doses were in between the A and B. DISCUSSION AND CONCLUSION: For the rectal and bladder doses most important factors are patient's age, disease stage, duration between EBRT and HDR-ICRT and patient anatomy, but these differences can be minimized to some extent by careful application, proper packing and proper fixation.
