Role of anti-Her-2 therapy in bladder carcinoma.

Bladder cancer, in its advanced stage, has very few therapeutic strategies with proven efficacy. Platinum-combination chemotherapy can be considered a standard for first-line therapy, but after progression there is no standard therapy, and the prognosis is very poor. The development of targeted therapies in the last few years has significantly changed the prognosis of a wide variety of tumors. In bladder cancer, there is no targeted therapy currently approved for its use in advanced disease. There is evidence that Her-2 amplification and/or overexpression is seen in bladder cancer, and may influence prognosis. Anti-Her-2 drugs, such as trastuzumab or lapatinib, are under investigation in urothelial neoplasms, but there is no phase III trial that has evaluated their use in bladder cancer. We review the published evidence about Her-2 determination, its influence on bladder carcinoma prognosis, the clinical development of anti-Her-2-targeted therapies, and the possible future research directions involving this pathway in bladder cancer.

Adjuvant chemotherapy for breast cancer and cognitive impairment.

Complaints of loss of memory and lack of concentration have been reported by long-term survivors of breast cancer. This mild cognitive impairment (MCI), also called "chemobrain" or "chemofog," has been the subject of a number of studies in the last few years. This cognitive impairment, although usually mild, must be studied to define possible risk factors for its development, and for future research into a preventive or therapeutic treatment approach. Long-term survivors of breast cancer must be followed to detect possible treatment sequelae as soon as possible. Since the number of these long-term survivors has increased in the last years, in part because of more active adjuvant treatments, our knowledge about the long-term side effects of these therapies has also grown.
