Overall survival of prostate cancer from Sangrur and Mansa cancer registries of Punjab state, India.

Introduction: There is a scarcity of population-based prostate cancer survival data in India. We assessed the population-based, overall survival of patients with prostate cancer from the Sangrur and Mansa cancer registries of the Punjab state, India. Methods: In the year 2013-2016, a total of 171 prostate cancer cases were registered in these two registries. Based on these registries, survival analysis was performed using the date of diagnosis as the starting date and the last follow-up date being December 31, 2021 or the date of death. Survival was calculated using STATA software. Relative survival was calculated using the Pohar Perme method. Results: Follow up was available for all the registered cases. Of the 171 cases, 41 (24%) were alive and 130 (76.0%) were dead. Of the prescribed treatments, 106 (62.7%) cases completed the treatment and 63 (37.3%) cases did not complete the treatment. Overall, 5-year age-standardized prostate cancer relative survival was 30.3%. Patients who completed the treatment had a 7.8 times higher 5-year relative survival (45.5%) compared to those who did not (5.8%). The difference between the two groups is statistically significant (hazard ratio 0.16, 95% confidence interval [0.10-0.27]). Conclusion: To improve survival, we need to raise awareness in the community and among primary physicians so that prostate cancer cases can reach the hospital early and should be treated effectively. The cancer center should develop the systems in their hospital so that there will be no hurdles to the patients in treatment completion. We found a low overall relative survival among patients of prostate cancer in these two registries. Patients who received treatment had a significantly higher survival.

Evaluation of Data Quality of Four New Population Based Cancer Registries (PBCRs) in Chandigarh and Punjab, North India- A Quality Control Study.

BACKGROUND: Population based Cancer Registries(PBCRs) are hallmark of cancer surveillance and cancer control activity .The value of cancer registries rely heavily on underlying quality of their data. Current study assessed data quality of four new PBCRs of Chandigarh, SAS Nagar, Mansa and Sangrur covering a total population of 4.5 millions on three quality parameters i.e. comparability, validity and completeness as recommended by International Agency of Research on Cancer(IARC), Lyon, France. METHODS: For assessing comparability, data of the registries were reviewed in terms of system of classification and coding, definition of incidence date and rule for multiple primaries. For assessing validity (Accuracy) four different methods i.e. re-abstraction and re-coding, percentage morphologically verified cases (MV%), percentage of death certificate only (DCO%) cases and percentage of cases with other and unspecified sites (O and U%) were used. For assessing completeness of coverage, different semi-quantitative methods were used. RESULTS: Re-abstraction done for 10% of the total incident cases yielded overall percentage agreement of 97.4%, 97.2%, 95.4% and 94.9% for PBCR Chandigarh, SAS Nagar, Mansa and Sangrur respectively. MV% was found to be 96.3% for PBCR Chandigarh, 92.8% for PBCR SAS Nagar , 89.3% for PBCR Mansa and 82.9% for PBCR Sangrur. Percentage of DCO cases and O and U cases were 1.4% and 2.8% for PBCR Chandigarh, 3.9% and 5.3% for SAS Nagar, 6.4% and 16.4% for Mansa and 6.3% and 8.3% for Sangrur. Completeness assessed through the various methods showed good level of completeness at PBCR Chandigarh and SAS Nagar and somewhat lower but acceptable level of completeness at PBCR Mansa and Sangrur. CONCLUSIONS: All the four PBCRs are comparable internationally. PBCR Chandigarh and SAS Nagar, predominantly urban registries, have higher accuracy of their data and good completeness levels as compared to predominantly rural registries of Mansa and Sangrur. Cancer estimates given by all the four registries are reliable and data from these registries can be utilized for planning cancer prevention and control activities in the region.

A Systematic Study of the Prevalence and Risk Factors of CKD in Uddanam, India.

INTRODUCTION: Despite reports of a high prevalence of chronic kidney disease (CKD) from the coastal Uddanam region of Andhra Pradesh, India, there are no accurate data on the distribution of kidney function abnormalities and CKD risk factors in this region. METHODS: A total of 2419 participants were recruited through multistage cluster random sampling from 67 villages. Serum creatinine and urine protein creatinine ratio were measured using validated methodologies. All abnormal estimated glomerular filtration rate (eGFR) and urine protein creatinine ratio values were reconfirmed after 3 months. A range of sociodemographic factors were evaluated for their association with CKD using Poisson regression. RESULTS: Of 2402 eligible subjects (mean ± SD age, 45.67 ± 13.29 years; 51% female), 506 (21.07%) had CKD (mean ± SD age, 51.79 ± 13.12 years; 41.3% female). A total of 246 (10.24%) had eGFR <60 ml/min/1.73 m2, whereas 371 (15.45%) had an elevated urine protein creatinine ratio (>0.15 g/g). The poststratified estimates, adjusted for age and sex distribution of the region for CKD prevalence, are 18.7% (range, 16.4%-21.0%) overall and 21.3% (range, 18.2%-24.4% ) and 16.2% (range, 13.7%-18.8%) in men and women, respectively. Older age, male sex, tobacco use, hypertension, and family history of CKD were independently associated with CKD. Compared with those with higher eGFR, those with eGFR <60 ml/min/1.73m2 were older, were more likely to be uneducated, manual laborers/farmers, or tobacco users, and were more likely to have hypertension, a family history of CKD, a diagnosis of heart disease, and a lower body mass index. Among those with low eGFR, there was no difference between those with urine protein creatinine ratio <0.15 or >0.15, except a lower frequency of males in the former. CONCLUSION: We confirmed the high prevalence of CKD in the adult population of Uddanam. The cause was not apparent in a majority. Subjects with a low eGFR with or without elevated proteinuria were phenotypically distinct from those with proteinuria and preserved eGFR. Our data suggest the need to apply a population-based approach to screening and prevention and studies to understand the causes of CKD in this region.

Effect of health education on awareness about oral cancer and oral self-examination.

CONTEXT: Oral cancer is preceded by visible changes in the oral mucosa. These lesions can be detected by oral self-examination, but awareness about oral cancer is still low in developing countries. AIM: To evaluate the effect of health education on awareness about oral cancer and oral self-examination. SETTINGS AND DESIGN: Quasi-experimental trial was conducted in an urban resettlement colony of Chandigarh, India. MATERIALS AND METHODS: A brochure having information and pictorials on oral lesions was used for conducting health education sessions on a one-to-one basis in the household setting among 85 males in age group 15-59 years during 2013, and each participant was encouraged to perform an oral self-examination. Study participants were interviewed about their awareness on oral cancer and oral self-examination before- and after-health education using a pretested interview schedule. STATISTICAL ANALYSIS: Awareness items were scored, and mean change in awareness score was computed. Paired t-test was used for testing statistical significance. RESULTS: Thirty-three percent of the study participants were current smokers, 25% consumed alcohol, and 9.4% chewed tobacco. The awareness scores after health education increased significantly from 5.3 to 6.7 (P < 0.05), and 34% of the tobacco or alcohol users expressed their intention to quit these habits, and two persons actually quit tobacco chewing. Out of the 77 study participants who performed oral self-examination, nine were able to detect lesions, and one was found to have submucous fibrosis. CONCLUSIONS: Health education intervention was able to initiate a favorable behavior change in the community. Hence, oral self-examination programs should be promoted.
