Tumor- and treatment-related factors were analyzed to generate a prognostic model. PATIENTS AND METHODS: Between May 1989 and April 2002, 120 patients received conventional-dose chemotherapy, surgery, and sequentially developed single- or tandem-cycle DICT. Disease- and treatment-specific features were subjected to univariate and multivariate analysis to correlate with outcome. RESULTS: At a median follow-up of 61 months (range, 21 to 161 months), estimated 5-year relapse-free survival (RFS) and overall survival (OS) were 44% (95% CI, 34% to 53%) and 64% (95% CI, 55% to 73%), respectively. In an age-adjusted multivariate analysis, RFS was better in patients with estrogen receptor (ER)/progesterone receptor (PR)positive tumors (P = .002), for patients with fewer than four involved axillary nodes before DICT (P = .01), and in patients treated with radiation therapy (P = .001) and tandem DICT (P = .049). OS was improved in patients with ER/PR-positive tumors (P = .002), in those with fewer than four involved axillary nodes before DICT (P = .03), and in patients treated with radiation therapy (P = .002). CONCLUSION: This retrospective analysis suggests that either single or tandem DICT can be administered safely and may benefit selected patients with stage IIIB IBC. Those with receptor-negative IBC and with four or more involved axillary nodes before DICT need improved neoadjuvant and postadjuvant intensification therapy. A prospective randomized trial of single versus tandem DICT would be required to confirm the potential benefit of tandem DICT in the setting of IBC. Supported by grant Nos.
