Vitamin D Levels

Studies have shown that vitamin D could have a role in breast cancer survival; however, the evidence of the relationship between patients’ vitamin D levels and their survival has been inconsistent. This meta-analysis explores possible dose-response relationships between vitamin D levels and overall survival by allowing for differences in vitamin D levels among populations of the various studies. Studies relating vitamin D (25-OH-D [25-hydroxyvitamin D]) levels in breast cancer patients with their survival were identified by searching PubMed and Embase. A pooled HR (hazard ratio) comparing the highest with the lowest category of circulating 25-OH-D levels were synthesized using the Mantel-Haenszel method under a fixed-effects model. A two-stage fixed-effects dose-response model including both linear (a log-linear dose-response regression) and nonlinear (a restricted cubic spline regression) models were used to further explore possible dose-response relationships. Six studies with a total number of 5984 patients were identified. A pooled HR comparing the highest with the lowest category of circulating 25-OH-D levels under a fixed-effects model was 0.67 (95% confidence interval = 0.56-0.79, P < .001). Utilizing a dose-response meta-analysis, the pooled HR for overall survival in breast cancer patients was 0.994 (per 1 nmol/L), Pfor linear trend < .001. At or above a 23.3 nmol/L threshold, for a 10 nmol/L, 20 nmol/L, or 25 nmol/L increment in circulating 25-OH-D levels, the risk of breast cancer overall mortality decreased by 6%, 12%, and 14%, respectively. There was no significant nonlinearity in the relationship between overall survival and circulating 25-OH-D levels. Our findings suggest that there is a highly significant linear dose-response relationship between circulating 25-OH-D levels and overall survival in patients with breast cancer. However, better designed prospective cohort studies and clinical trials are needed to further confirm these findings.

Mistletoe preparations such as Iscador are in common use as complementary/anthroposophic medications for many cancer indications, particularly for solid cancers. The efficacy is still discussed controversially. This paper presents an individual patient data meta-analysis of all published prospective matched-pair studies with breast cancer patients concerned with long-term application of a complementary/anthroposophic therapy with the mistletoe preparation Iscador. Six sets of data were available for individual patient meta-analysis of breast cancer patients, matched according to prognostic factors into pairs with and without mistletoe (Iscador) therapy. The main outcome measures were overall survival and psychosomatic self-regulation. Overall survival was almost significant in favor of the Iscador group in the combined data set of the randomized studies: estimate of the hazard ratio with 95% confidence interval 0.59 (0.34, 1.02). Overall survival was highly significant in the combined data set of the non-randomized studies: 0.43 (0.34, 0.56). In the combined analysis of the randomized studies, improvement of psychosomatic self-regulation, as a measure of autonomous coping with the disease, was highly significant in favor of the Iscador group: estimate of the median difference 0.45 (0.15, 0.80),P= 0.0051. The analyzed studies show that therapy with Iscador might prolong overall survival and improve psychosomatic self-regulation of breast cancer patients.

BACKGROUND: Breast conserving surgery followed by postoperative radiotherapy, as alternative to radical mastectomy, has been accepted as an optimal method for loco- regional treatment of the majority of women with early stage of breast carcinoma. The aim of the study was to evaluate the results of postoperative radiotherapy after breast conserving surgery in the Institute for oncology and radiology of Serbia. METHODS: During the 3-year period, 109 breast cancer patients with stage I and II were treated with postoperative radiotherapy after breast conserving surgery. Ninety- four patients underwent quadrantectomy with axillary node dissection, and 15 patients underwent only tumorectomy. After surgery all patients received postoperative radiotherapy to the whole breast with tumor dose 50 Gy in 15 fractions every second day. In 52 patients radiotherapy was given to the regional lymphatics with tumor dose 45 Gy in 15 fractions every second day. Twenty-eight patients received a booster dose (10 Gy) to the tumor bed. Adjuvant systemic therapy was administered depending on the nodal involvement and steroid receptors content: 17 patients received adjuvant chemotherapy (CMF or FAC), 18 received adjuvant hormonal therapy (tamoxifen or ovarian ablation), and 6 patients received both chemo- and hormonotherapy. RESULTS: After median follow-up period of 62 months, there was no evidence of loco- regional recurrence in anyone of patients. Distant metastases occurred in 7 patients (6.4%) with median disease free interval of 27.6 months. At last follow-up 91 patients (83.4%) were alive, 4 patients (3.7%) were dead of disease, and the same number was dead of other causes. The 5-year overall survival rate was 92.9% and disease-free survival rate was 92.7%. CONCLUSION: According to our results the combined surgery and radiotherapy approach provides good local control of early breast cancer patients. Postoperative radiotherapy after breast conserving surgery with or without adjuvant systemic therapy has important role in adjuvant treatment of early breast cancer.
