Andrea De Censi, MD, director of the medical oncology unit at the National Hospital E.O. Ospedali Galliera–SC Oncologia Medica in Genoa, Italy, discusses the results of the phase III TAM-01 trial in breast cancer.

This trial randomized 500 women with operated hormone sensitive breast ductal or lobular carcinoma in situ to receive either low-dose tamoxifen or placebo to assess the potential recurrence risk reduction. After a median follow-up of 5 years, results showed a 52% reduction in the risk of recurrence with low-dose tamoxifen compared with placebo, says De Censi, meeting the criteria for statistical significance.

Moreover, there were 14 (5.5%) events of disease recurrence in the tamoxifen arm versus 28 (11.3%) in the placebo arm (HR, 0.48; 95% CI, 0.26-0.92; P = .024). The number of events has been relatively low, he adds. More follow-up is needed to assess the benefit of low-dose tamoxifen in this patient population.
