Summary
The Bombay Cancer Registry
Area of Science:
- Oncology
- Epidemiology
- Public Health
Background:
- The Bombay Cancer Registry, established in 1963, is India's first population-based cancer registry and Asia's second oldest.
- It employs active methods for case registration and follow-up, ensuring comprehensive data collection.
- This study analyzes survival data for 28 cancer types registered between 1992 and 1999.
Purpose of the Study:
- To report 5-year age-standardized relative survival rates for common cancers in India.
- To evaluate the impact of disease extent and age on cancer survival.
- To assess the quality of data through histological verification and follow-up completeness.
Main Methods:
- Survival data analysis for 28 cancer sites/types registered from 1992-1999.
- Active follow-up methods employed, with median follow-up ranging from 1-51 months.
- Inclusion of 84-99% of registered cases in survival analysis, with 5-year follow-up completeness between 85-92%.
Main Results:
- Five-year relative survival rates: Breast (48%), Cervix (44%), Lung (11%), Oesophagus (14%), Oral Cavity (35%), Non-Hodgkin Lymphoma (34%).
- Survival rates showed inverse or fluctuating relationships with age groups.
- Regional disease spread was highest for tongue, oral cavity, larynx, and cervix cancers, with survival decreasing as disease extent increased.
Conclusions:
- Cancer survival rates in India vary significantly by cancer type and stage.
- Early detection and intervention are crucial, particularly for cancers with high regional spread.
- The Bombay Cancer Registry provides vital data for understanding cancer epidemiology and improving patient outcomes in India.

01:21Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
01:24Kaplan-Meier Approach
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
01:20Comparing the Survival Analysis of Two or More Groups
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and Cox...
01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
