Which cancer is least likely to be treated with concurrent chemotherapy and radiation?

1. Breast cancer

2. Prostate cancer

3. Head and neck cancer

4. Gastric cancer

The correct answer is: Breast cancer

The treatment of breast cancer typically involves surgery, hormonal therapy, and radiation, but concurrent chemotherapy and radiation are generally not the standard approach for this type of cancer. This is primarily because breast cancer often has well-established treatment protocols that focus on surgery followed by adjuvant therapy, where chemotherapy is provided after radiation rather than at the same time. In contrast, prostate cancer, head and neck cancer, and gastric cancer frequently utilize concurrent chemotherapy and radiation as part of their treatment regimens. For example, these modalities together can enhance the effectiveness of treatment in cases of more aggressive tumors or in specific stages of disease, making them more common in these cancers. The synergy of concurrent treatment can improve local control and overall survival rates for those cancer types.
