RESUMEN
BACKGROUND: The use of complementary and alternative medicine (CAM) has escalated over the past decade, despite the fact that clinical studies validating the efficacy of CAM remain sparse. Clinicians frequently encounter patients who reject standard treatment, but data on outcomes of patients choosing CAM as primary treatment for breast cancer are also lacking. MATERIALS AND METHODS: Breast cancer patients who refused/delayed standard treatments in favor of alternative therapies were identified in a community surgical practice over a 10-year period. A retrospective chart review was performed with telephone interviews when possible. Estimated 10-year survival given recommended treatment was calculated. RESULTS: A total of 61 patients was identified; median age was 53. Median follow-up was 54 months. Patients were stratified into 2 subgroups: those who omitted/delayed surgery (SSG, n = 26) and those who were nonadherent to adjuvant therapy recommendations (ASG, n = 35). In the SSG, 96.2% experienced disease progression; 50% died of disease. Mean stage at initial presentation was II; mean stage at re-presentation after primary treatment with alternative therapies was IV. Disease progression occurred in 86.2% of those in the ASG; 20% died of disease. The mean 10-year survival calculated for those omitting surgery was 69.5%; observed survival for this group was 36.4% at a median follow-up of 33 months. CONCLUSIONS: Alternative therapies used as primary treatment for breast cancer are associated with disease progression and increased risk of recurrence and death. Diminished outcomes are more profound in those delaying/omitting surgery. Reviewing these results with our patients may help bridge the gap between CAM and standard treatments.

BACKGROUND: Breast-specific gamma imaging (BSGI) is a functional imaging modality that has comparable sensitivity but superior specificity compared with magnetic resonance imaging, yielding fewer false-positive results and thereby improving clinical management of the newly diagnosed breast cancer patient. METHODS: A retrospective review was performed from 2 community-based breast imaging centers of newly diagnosed breast cancer patients in whom BSGI was performed as part of the imaging work-up. RESULTS: A total of 138 patients (69 invasive ductal carcinoma, 20 invasive lobular carcinoma, 32 ductal carcinoma in situ, and 17 mixtures of invasive ductal carcinoma, invasive lobular carcinoma, or ductal carcinoma in situ and other) were reviewed. Twenty-five patients (18.1%) had a positive BSGI study at a site remote from their known cancer or more extensive disease than detected from previous imaging. Fifteen patients (10.9%) were positive for a synchronous or more extensive malignancy in the same or contralateral breast. Five patients had benign findings on pathology, 5 benign on ultrasound follow-up (false-positive rate, 7.2%). Findings converted 7 patients to mastectomy, 1 patient to neoadjuvant chemotherapy, and 7 patients were found to have previously undetected contralateral cancer. The positive predictive value for BSGI was 92.9%. CONCLUSIONS: BSGI detected additional or more extensive malignancy in the same or contralateral breast in 10.9% of newly diagnosed breast cancer patients. Only 7.2% incurred an additional work-up. BSGI provides accurate evaluation of remaining breast tissue in newly diagnosed breast cancer patients with few false-positive readings.
