Descriptive epidemiology of bone cancer in greater Bombay.

Bone tumours are comparatively uncommon, constituting only 0.5% of the total world cancer incidence. As Bone tumors consist of several distinct clinico-pathological entities, descriptive epidemiology of tumors at this site can be based only on studies where they can be distinguished.

Descriptive epidemiology of leukaemias in Greater Mumbai.

Background: There is little data available on the occurrence of leukaemias in India. This is despite a large number of patients being diagnosed and treated at various cancer centres all over the country. We, therefore, analysed the available data of the Bombay Cancer Registry to ascertain the epidemiological characteristics of leukaemias in India.

Descriptive epidemiology of lymphatic malignancies in Greater Bombay.

Lymphoid malignancies as a group constitute one of the important cancers met in India as elsewhere in the world, but while information on incidence, mortality, survival and trends, are available from most of the developed countries, there are very few reports available from the rest of the world. The basic data utilized for this study was obtained from the Bombay Cancer Registry, the first population based registry to be established in India. Descriptive epidemiology of these malignancies was obtained by utilizing 5-year data of incidence and mortality of different cell types in males and females.

Descriptive epidemiological assessment of urinary bladder & kidney cancers in Greater Bombay.

For studying the descriptive epidemiology of cancers of the urinary bladder and kidney, the data reported by Bombay Cancer Registry for the most recent five years have been utilised. For studying time trends in these cancers, data of the past 30 yr have been used. In Bombay, bladder cancer is very uncommon in the first three decades of life; but after the age of 30, the incidence rates increase with age, in log-linear fashion, in both sexes.

Uterine cervical adenocarcinomas and squamous carcinomas in Bombay: 1965-1990.

Objective: To learn if the increased incidence of uterine cervical adenocarcinomas in developed populations exists in developing ones.

Methods: We studied age-adjusted (world) incidence rates of pathologic types of cervical cancer from 1965 through 1990 in the population-based Bombay Cancer Registry and in the National Cancer Registry's hospital-based frequencies of 1985-1987. The t-test was used to measure the statistical significance of change.

Vasectomy and prostate cancer: a case-control study in India.

Background: The role of vasectomy in the development of prostate cancer remains controversial. In particular, there has been concern about detection bias and confounding in the previously published epidemiological studies examining this hypothesis. With the goal of minimizing detection bias, we have evaluated the relation between vasectomy and prostate cancer in a population without routine prostate cancer screening.

Descriptive epidemiological assessment of cancers of the breast, ovary and uterine corpus in Greater Bombay.

An attempt has been made to make a descriptive epidemiological assessment of cancers of the breast, uterine corpus and ovary in Greater Bombay. The descriptive epidemiology has been discussed in relation to age and demographic and socio-economic composition of the population, utilising the recent 5 year data. The incidence of these cancers in Bombay has been compared with national and international findings.

Descriptive epidemiology of the cancers of male genital organs in greater Bombay.

For different reasons cancers of the Prostate, Testis and Penis are important diseases for men. The incidence for prostate and testicular cancers are more commonly seen in developed countries, while penile cancer occurs more frequently in the developing countries. In Mumbai the incidence of prostatic and testicular cancers is low whereas penile cancer is high when compared with international reports.

The descriptive epidemiology and trends in incidence of nonocular malignant melanoma in Bombay and India.

Nonocular malignant melanoma is a rare but lethal disease increasing in incidence and mortality in western countries with improved survival if diagnosed and treated early. This study reports its epidemiology from cancer registry data in six different parts of India; its anatomic distribution and trends in Bombay from 1964 to 1984. Age-adjusted incidence in Bombay patients shows no increase from 1964 to 1984 unlike in white caucasians.

Trends in cancers of the upper alimentary and respiratory tracts in women in bombay, India.

Cancers of the upper alimentary and respiratory tracts are proven to be causally associated with tobacco use and are therefore preventable. These cancers form 50% of all cancers in men and 20% in women in Bombay. This study reports on the trends in women for these cancers (observed in the Bombay Cancer Registry during 1964-81) which were found to be by and large similar to those reported elsewhere for males.

Geographic differences in cancer incidence by sex at various sites in city wards in Greater Bombay.

In this paper an attempt has been made to study the geographic variations in cancer incidence at various sites, by sex, in Greater Bombay. Crude incidence rates at each site for individual wards have been calculated using the data collected by the Bombay Cancer Registry, for the years 1979 to 1984. To study the variations highest and lowest crude incidence rates in the different wards and the ratio of the highest to the lowest rates for each primary site were calculated.

Trends in breast cancer incidence in greater Bombay: an epidemiological assessment.

Reliable data from the Bombay Cancer Registry show an increase in the age-adjusted incidence rate of breast cancer in women from 17.9 to 24.9 per 100,000 population between 1965 and 1985.

Declining trend in cervical cancer incidence in Bombay, India (1964-1985).

Population-based incidence rates for cervical cancer in Bombay showed a decline over the past two decades. The observed rates fitted to a log linear regression model showed a good fit. In an attempt to explain the observed decline, cohort-specific age incidence curves were drawn, cumulative incidence rates over common age ranges estimated, and the log linear model fitted separately for each of the religious groups that showed diverse age-adjusted rates for cervical cancer.

Cancer in young adults between the ages of 15 and 34 years in Greater Bombay.

An attempt has been made in this study to examine the nature and magnitude of the cancer problem in young adults between the ages of 15 and 34 years living in Greater Bombay. The morbidity data utilised for this exercise were obtained from the Bombay Cancer Registry and the mortality analysis was made from the death records maintained by the Bombay Municipal Corporation. In Greater Bombay, the ratio of cancer incidence in this specific group as compared with the total incidence of the disease in the general population was very high in comparison with the Western incidence.

Cancer incidence in Indian Christians.

Differences in habits, customs and ethnic characteristics have provided important leads for the study of cancer in Indian Christians. It is a sign of the times that some of the social customs rigidly upheld by the older generations are rapidly giving way to "Modernism". An attempt has been made to examine the differences found in the site-specific cancer risks in this community in Bombay.

Cancer in Indian Moslems.

Moslems are the followers of Islam who, during the time of the Ghaznavid dynasty of Afghanistan, invaded India for the first time. Islam attaches equal importance to material and spiritual aspects of human life. Men and women have equal cultural rights.

Epidemiology of cancer of the cervix in greater Bombay.

An attempt has been made to study in depth the cervical cancer problem in Greater Bombay by undertaking epidemiological investigations to identify its aetiology, by utilising the data collected by the Bombay Cancer Registry. Although cancer of the uterine cervix is found to occur at all ages in Bombay, it is mainly seen during middle age. Its incidence is highest in the Hindu community and lowest in the Parsi.
