SEVERAL studies have been made in recent years to evaluate the effect of socioeconomic factors on the survival rates of cancer patients. Analysis of the California Tumor Registry [I] data showed that survival rates of cancer patients admitted to city hospitals in the period 1942-1956 were significantly less favorable than those of patients admitted to private hospitals. Some of the difference disappeared, however, when the analyses were confined to the same extent of spread of the malignant disease, thus indicating that the poor prognosis of cancer patients in city hospitals was partly due to more advanced disease. Cohart 12-41 and Cohart and Muller 151 found that lower socio-economic status was associated with poorer survival for patients with breast cancer, but not for females with cancer of other genital organs or males and females with cancer of the gastrointestinal tract or lung. On the other hand, no significant differences were found in the survival rates of cancer sufferers in an investigation [6] of cancer end-results in several cities of the USA when these patients were separated into two socio-economic levels according to the census tracts in which these patients were domiciled. A study [7] of the end-results of English women with cervical cancer treated in 1945-1948 again showed no association with socio-economic factors. In the English study the patients were separated into socio-economic groups by using occupational information. In none of these studies were the published survival rates adjusted to account for the high proportion of elderly patients usually found in low socio-economic areas, but in the California Tumor Registry Investigation, the effect on these rates of different age distribution was tested in the two types of hospitals and found to be negligible.In common with the State Tumor Registries of Connecticut and California, the Massachusetts State Registry is a member of the End Results Group of the National Cancer Institute, and consequently the coding rules are similar in all three registries. Analyses made by the End Results Group covering the period 19451959 have shown that survival rates for most sites were consistently poorer in Massachusetts than Connecticut [8]. The reason for the differences in observed survival was thought to be mainly related to the fact that in Massachusetts only selected institutions had registered their tumor patients with the State Registry. As a consequence of its history-it was founded in 1926 to register patients treated at state-aided cancer clinics for the indigent population-the Massachusetts Registry included a relatively
