The influence of delay time on the survival of patients with carcinoma of the breast in British Columbia Moorehead, William P.
Abstract
The question asked in this thesis is, "What is the influence of delay time on the survival of patients with carcinoma of the breast in British Columbia"? A preliminary data review was carried out on records of the Cancer Control Agency of British Columbia for the years i960, 1961 and 1970 to explore possible changes in delay time and the methodology of the present study. The years 1960 to 1964 inclusive and the two delay periods, under one month and one year and over, were chosen for study. A total of 456 cases from both delay periods was available for comparison. Life Tables were used for analysis of the two delay periods and their survival from date of diagnosis and date of first symptom. No strong relationship was found between short delay and survival. In fact, in the initial years, those who had long delay appeared to do better, although in the long term short delay appeared to have an advantage. Again with Life Tables, the two delay periods and survival were explored in each of the four clinical stages of the disease. This showed that in clinical stages I and II, the long delay group survived longer. The opposite was true in clinical stages III and IV. The implications for health planning are discussed.
