Tamoxifen and radiotherapy: Tackling breast cancer with tamoxifen after surgery and radiation in women over 70 years seems pointless. For women aged 50 years, this approach is sensible for local metastases, although again no difference in getting remote metastasis and survival between the two groups, according to recently published randomized trials. Article updated March 28, 2011.

Randomized studies have shown that women with breast cancer over 70 years operation and tamoxifen is as effective as surgery and radiation and tamoxifen and with no additional irradiation seems postief effect for women older than 70 years. Another randomized study shows this approach in women over 50 years have a significant positive effect on local recurrence. Irradiation provides additional side effects and is of course much more intensive for the patient.

In the study in women over 70 years to five years was no difference observed between the two groups. In the study in women aged 50 years show the difference significantly better on whether to get local metastases. Both studies also no difference in whether or not to get remote metastases and no difference in survival. In the study of women aged 50 years, there was no difference in survival between women who have breast cancer and women who were not further irradiated. Moreover, several studies have shown that other hormone treatments, and better than tamoxifen efectiever. See more information about under -breast cancers . Perhaps with good diet and some extra vitamins and minerals and anti-oxidant effect of these treatments are improving, but before you have to do a consultation with a qualified orthomolecular doctor. Thus, for example, a study found that GLA ​​is many in evening primrose oil to supplement the effect of radiation appears to increase the side effects and significantly.

BACKGROUND: In women 70 years of age or older who have early breast cancer, it is Unclear whether lumpectomy plus tamoxifen is as effective as lumpectomy followed by tamoxifen plus radiation therapy.

METHODS: Between July 1994 and February 1999, we randomly Assigned 636 women who were 70 years of age or older and who had clinical stage I (T1N0M0 According To the tumor-node-metastasis classification), estrogen receptor-positive breast carcinoma Treated by lumpectomy plus radiation therapy to receive tamoxifen (317 women) or tamoxifen alone (319 women). Primary end points were the time to local or regional recurrence, the frequency of mastectomy for recurrence, breast-cancer-specific survival, the time to distant metastasis, and overall survival.

RESULTS: The only significant difference Between the two groups was the rate of local recurrence at five years or regionalism (1 percent in the tamoxifen plus irradiation group Given and 4 percent in the tamoxifen group Given alone, P <0.001). There were no significant differences with regard Between the two groups to the rates of mastectomy for local recurrence, distant metastases, or five-year rates of overall survival (87 percent in the tamoxifen plus irradiation group Given and 86 percent in the tamoxifen group, P = 0.94). Assessment by physicians and patient or cosmetic results and adverse events uniformly rated tamoxifen plus irradiation inferior to tamoxifen alone.

CONCLUSIONS: lumpectomy plus adjuvant therapy with tamoxifen alone is a realistic choice for the treatment of women 70 years of age or older who have early, estrogen-receptor-positive breast cancer. Copyright 2004 Massachusetts Medical Society

BACKGROUND: We Determined the effect of breast irradiation plus tamoxifen on disease-free survival and local relapse in women 50 years of age or older who had T1 or T2 node-negative breast cancer.

METHODS: Between December 1992 and June 2000, 769 women with early breast cancer (tumor diameter, 5 cm or less) were randomly receive breast irradiation plus Assigned to tamoxifen (386 women) or tamoxifen alone (383 women). The median follow-up was 5.6 years.

RESULTS: The rate of local relapse at five years was 7.7 per cent in the Tamoxifen group and 0.6 per cent in the Group Given Tamoxifen plus irradiation (hazard ratio, 8.3; 95 percent confidence interval, 3.3 to 21.2, P <0.001), with corresponding thing five -year disease-free survival rates of 84 percent and 91 percent (P = 0.004). A planned subgroup analysis of 611 women with T1, receptor-positive tumors benefit from a Indicated radiotherapy (five-year rates of local relapse, 0.4 percent with tamoxifen plus radiotherapy and 5.9 percent with tamoxifen alone, P <0.001). Overall, there was a significant difference in the rate of axillary relapse at five years (2.5 percent in the tamoxifen group and 0.5 percent in the tamoxifen plus irradiation group Given, P = 0.049), but no significant difference in the rates of distant relapse or overall survival.

CONCLUSIONS: As compared with tamoxifen alone, radiotherapy plus tamoxifen significantly Reduces the risk of breast and axillary recurrence after lumpectomy in women with small, node-negative, hormone receptor-positive breast cancers. Copyright 2004 Massachusetts Medical Society
