Five-year survival in breast cancer treated with adjuvant immunotherapy.
In this follow-up report of the treatment of primary breast cancer with adjuvant immunotherapy, a total of 95 patients were studied: 46 patients with stage I breast cancer and 49 patients with stage II breast cancer. All patients underwent standard surgical treatment and received immunotherapy as adjuvant treatment. Patients received a primary series of eight doses (1 mL of tumor-associated antigen preparation given as 0.2 mL intradermally and 0.8 mL subcutaneously) given over 8 weeks, and then booster injections every 3 months for at least 2 years. The 5-year survival with adjuvant immunotherapy was 83% for those with negative axillary nodes and 53% for those with positive nodes; this compares favorably with national 5-year survival statistics from two other studies (node-negative, 72% and 83%; node-positive, 51% and 59%). Based on these data, the addition of immunotherapy to other adjuvant therapies in randomized prospective trials seems both reasonable and justified.
