Breast cancer is the most common female cancer and the second most common cause of cancer death in women. BC incidence is markedly increased with aging.
Amplification or overexpression of HER2 oncogene is present in approximately 18 to 20% of primary invasive BC. In the absence of HER2 target therapy combined with adjuvant or neoadjuvant chemotherapy, HER2 overexpression or amplification is associated with high rates of disease recurrence and death.
There is major concern regarding chemotherapy related toxicity in the group of women older than 65 years old diagnosed with HER2 positive breast cancer. Nevertheless, these patients are at a particularly high risk of breast cancer recurrence and death. Of note, older patients may experience higher risk for Trastuzumabe related cardiotoxicity, especially when this agent is combined with an anthracycline.
Recent studies have shown extremely favourable outcomes in early HER2+ BC patients treated with a combination of paclitaxel and trastuzumab, omitting anthracyclines from treatment.
Investigators sought to investigate safety and outcome data on a cohort of elderly patients treated with weekly paclitaxel combined with carboplatin and trastuzumab.
