Tamoxifen is an effective treatment for breast cancer but an undesirable side-effect is an increased risk of endometrial cancer, particularly rare tumor types associated with poor prognosis. We investigated whether tamoxifen therapy increases mortality among breast cancer patients subsequently diagnosed with endometrial cancer. We pooled case-patient data from the three largest case-control studies of tamoxifen in relation to endometrial cancer after breast cancer (1,875 patients: Netherlands, 765; United Kingdom, 786; United States, 324) and collected follow-up information on vital status. Breast cancers were diagnosed in 1972 to 2005 with endometrial cancers diagnosed in 1978 to 2006. We used Cox proportional hazards survival analysis to estimate hazard ratios (HRs) and 95% confidence intervals (CI). A total of 1,104 deaths occurred during, on average, 5.8 years following endometrial cancer (32% attributed to breast cancer, 25% to endometrial cancer). Mortality from endometrial cancer increased significantly with unfavorable non-endometrioid morphologies ( Patients with endometrial cancer after breast cancer who received tamoxifen treatment for five years for breast cancer have greater endometrial cancer mortality risk than those who did not receive tamoxifen. side effects of amoxicillin Some women with endometrial cancer have no symptoms until the disease has spread to other organs. But endometrial cancer is usually diagnosed by the appearance of symptoms -- like vaginal bleeding -- as the cancer begins to grow. The most likely symptoms are: You experience abnormal vaginal bleeding or discharge. Abnormal bleeding, though sometimes a symptom of menopause, should be brought to your doctor's attention immediately. Endometrial cancer usually doesn't occur before menopause, but it can appear around the time menopause begins and during the menopausal transition.

Consequently, a large number of women will be subjected to both the benefits and potential risks of long-term tamoxifen therapy. One of the most significant potential complications is the development of endometrial cancer. The estimated annual risk of endometrial cancer in tamoxifen-treated patients is approximately 2 per 1,000 women. There was a twofold increase in the risk of endometrial cancer following extended versus standard adjuvant tamoxifen therapy in patients with breast cancer, a meta-analysis found. The systematic review of four randomized controlled trials showed that the absolute risk of endometrial cancer in patients receiving adjuvant tamoxifen for 10 years was 3.2% compared with 1.5% in patients receiving 5-year standard therapy (cumulative risk ratio [RR] 2.29, 1.60 to 3.28, Most tamoxifen-related uterine cancers occurred in patients who were postmenopausal and symptomatic, but diagnosed at an early stage and with a low grade, and carried a mortality risk of less than 1%, the authors wrote in the "There is a paucity of clear evidence on how we should best manage endometrial cancer risk in extended tamoxifen therapy," said Fleming in a statement. "This is a research area that requires immediate focus with expansion of extended tamoxifen therapy regimes." Few studies have data on endometrial surveillance in patients on adjuvant tamoxifen, the most recent of which (2003) was part of this review and did not find any benefit for routine endometrial surveillance in patients receiving tamoxifen for 5 years. Guidelines published by the American College of Obstetricians and Gynecologists, plus those from the Australian and New Zealand group do not recommend routine surveillance in asymptomatic patients receiving tamoxifen. "Although it is difficult to make clear evidence-based recommendations on endometrial surveillance in the setting of extended therapy because of the sparsity of robust results, a practical approach may be to screen all patients using endometrial ultrasonography after 5 years on tamoxifen," they wrote. "The validity of this approach should be assessed prospectively." Regarding breast cancer outcomes, Fleming's group observed a non-significant reduction in breast cancer-specific mortality in patients receiving tamoxifen for 10 years, from 11.6% to 10.1% (RR 0.94, He added that there are "many factors to consider in choosing endocrine therapy," including menopausal status, risk of breast cancer recurrence, bone health, other comorbid conditions, and tolerance of estrogen deprivation. Soliman, who was not affiliated with the study, noted that the absolute increase in endometrial cancer rates was very small. Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs. Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, including uterine sarcoma, but they are much less common than endometrial cancer. Endometrial cancer is often detected at an early stage because it frequently produces abnormal vaginal bleeding, which prompts women to see their doctors. If endometrial cancer is discovered early, removing the uterus surgically often cures endometrial cancer.
