Paradox of wellness and nonadherence among Nigerian women on breast cancer chemotherapy.
(39/2129)
CONTEXT: Intentional nonadherence among cancer patients is rare and may occur only when the benefits of treatment are not obvious to the patient. AIMS: To highlight a group of women on chemotherapy for breast cancer who defaulted from their medications because they were improving. SETTINGS AND DESIGN: A study was carried out of the reasons for nonadherence to medications among women receiving chemotherapy for breast cancer at a Nigerian teaching hospital between January 1993 and December 2002. MATERIALS AND METHODS: A retrospective review of patients' records was done. RESULTS: Of the 188 women who received chemotherapy during the study period, 152 (80.9%) defaulted from treatment at one point or another. The reasons for nonadherence were available in 101 patients. Among these, 18 (18.0%) reported nonadherence because they felt better after commencing chemotherapy. They were aged 31-50 years (Mean = 35.6 (SD3.2)). Six (33.3%) of them presented in AJCC Stage I, and 10 (55.6%) in stage II. Age and disease stage at presentation were found to have significant influence on their reason for nonadherence. Of the nine women on neo-adjuvant chemotherapy, six (66.7%) had complete response but defaulted and five (55.6%) re-presented within a year with metastatic disease. Three of the patients receiving systemic post-surgery chemotherapy presented within a year with local recurrence. Most of the other patients were subsequently lost to follow-up. CONCLUSIONS: Nonadherence due to wellness among breast cancer patients is associated with poor outcome. We propose a detailed prospective study to establish factors that may influence such behavior.
