When considering treatment options for a 55-year-old man diagnosed with prostate cancer, which of the following is not typically included?

In the management of prostate cancer, especially in early-stage cases, the typical treatment options include surgical resection, a wait-and-see approach (active surveillance), and radiation therapy. These options are based on the cancer's stage, grade, and the patient's overall health, as well as their preferences.

Surgical resection involves the removal of the prostate and surrounding tissues, which can be curative and is commonly performed in localized disease. The wait-and-see approach is appropriate for patients with less aggressive forms of prostate cancer, where immediate treatment may not be necessary, and monitoring the cancer's progression is adequate. Radiation therapy is another standard treatment for localizations and can be offered as an alternative to surgery.

Chemotherapy is generally not considered a first-line treatment for early-stage or localized prostate cancer. It is typically reserved for advanced prostate cancer or cases that have become resistant to hormonal therapies. Therefore, chemotherapy as a first-line treatment is not usually included in the standard treatment protocols for newly diagnosed prostate cancer, making it the correct answer in this context.
