Ninety‐eight premenopausal patients with stage IV breast cancer were treated with chemoimmunotherapy alone, or with combination oophorectomy – chemoimmunotherapy either simultaneously (chemoimmunotherapy within four weeks of oophorectomy) or sequentially (delayed chemoimmunotherapy until evidence of progressive disease or no response to oophorectomy). The chemoimmunotherapy consisted of a three‐drug combination of Adriamycin, cyclophosphamide, and 5‐fluorouracil or Ftorafur; immunotherapy consisted of either oral levamisole, BCG by scarification, or a combination of both. Forty patients underwent simultaneous oophorectomy–chemoimmunotherapy, with a response rate of 85% and a median duration of response of 25 months. Response rate of 69% and a median duration of response of 16.6 months was observed with the 29 patients who received sequential oophorectomy–chemoimmunotherapy. Another 29 patients were treated with chemoimmunotherapy alone and achieved a response rate of 87% and a median duration of response of 11.8 months. Though there were no significant differences in the response rate, patients treated with chemoimmunotherapy alone had a significantly shorter median duration of response (P < 0.05). This would suggest that oophorectomy in combination with chemoimmunotherapy is the most favorable treatment modality for premenopausal patients with advanced metastatic breast cancer.
