Summary: | Background: Surgical management of localized breast cancer has changed dramatically in the past two decades. Randomized clinical trials of women with stage I or II lesions have shown there is no significant difference in survival rates between women receiving modified radical mastectomy (MRM) or breast conserving surgery (BCS). However, there are substantial regional variations in types of surgery for breast cancer. It would then seem that surgeons and patients' views could help explain such variations. This study aimed to clarity the numbers of MRM and of BCS performed within the Health Care Corporation of St. John's, Newfoundland during the years 1994-1997. In addition, the aim was to contrast the surgeons' view of the different types of surgical interventions for breast cancer with the views of women who had undergone different types of surgery. -- Method: The records of all surgeries for breast cancer, irrespective of staging of the disease, were extracted from the Health Care Corporation of St. John's (HCCSJ) for the period of 1994-1997 and coded according to the Canadian classification of diagnostic, therapeutic and surgical procedures (Statistics Canada, 1986). Chart audits were completed to ensure accuracy of the extracted data. All surgeons within the general surgery program of the HCCSJ who did breast cancer surgery regularly and consented to participate in the study completed a short questionnaire and were interviewed about their own surgical practices, their views of the decision making processes of women and which factors they felt impacted these particular patients' choices for surgical intervention for their breast cancer. Four focus groups and one private interview were organized with 21 women who had either MRM or BCS to provide them with the opportunity to discuss their surgery. The interviews and focus groups were taped, transcribed and common themes extracted. -- Results: A total of 363 surgeries were performed for breast cancer within the HCCSJ during 1994-1997. Of these 71.9% were MRM. ... |
