There was an alarming increase in tumours related to exposure to tobacco and alcohol, especially in women. Improved diagnostic techniques and treatment strategies coincided with improved prognosis. This was associated with an increased demand for health care.
Data were collected on all patients diagnosed with cancer between 1970 and 1999 in the south-eastern part of the Netherlands, the registration area of the Eindhoven Cancer Registry. Trends in age-specific and age-adjusted incidence, mortality, prevalence and relative survival were calculated. The changes in incidence were compared with changes in exposure to risk factors, such as smoking, alcohol, diet, infections and sunlight, and with early detection.
To describe the changes in incidence, mortality, survival and prevalence of cancer since 1970 in the south-eastern part of the Netherlands, the registration area of the Eindhoven Cancer Registry.
Descriptive population-based study.
The incidence of cancer of the stomach and uterine cervix decreased in the study period. Among men, the incidence of lung cancer increased sharply until the mid 1980s, whereafter it decreased. Furthermore, the incidence of cancer of the oesophagus, colon, rectum, breast, prostate and lung (in women), cutaneous melanoma and non-Hodgkin's lymphoma also increased. The survival improved for patients with cancer of the rectum, breast, female genital tract, prostate, testis (non-seminoma), cutaneous melanoma and Hodgkin's disease. The improvement in survival could be explained in part by early detection and partly by the improvement in treatment strategies. The prevalence of the diagnosis 'cancer' in living subjects increased by almost 30%, which may be related to the increase in incidence and the improvement in survival.
