OBJECTIVES: To describe the 5-year outcomes of patients with high-risk localized prostate cancer treated with neoadjuvant estramustine and vinblastine followed by concurrent chemotherapy and three-dimensional conformal radiotherapy (3D-CRT).

METHODS: A total of 23 patients completed therapy consisting of two 8-week cycles of vinblastine, weekly as 4 mg/m2, followed by 8 weeks of concomitant chemotherapy and 3D-CRT. Estramustine was given daily at 10 mg/kg in three divided doses. 3D-CRT consisted of a total dose of 7560 cGy.

RESULTS: Assessable patients include 9 with Stage T3 or greater tumors and 5 with lymph node metastasis at diagnosis. All patients had a Gleason score 7 or greater. The median follow-up was 60 months. Of the 23 assessable patients, 15 (65%) experienced biochemical relapse by American Society for Therapeutic Radiology Oncology criteria. The median time to prostate-specific antigen relapse was 12 months (range 7 to 16). Five patients (22%) developed metastases. The median time to metastasis had not been reached by last follow-up. Of the 23 assessable patients, 11 (48%) received no additional therapy and had noncastrate testosterone levels. Six patients had no evidence of disease and 9 patients were receiving androgen blockade. Three patients died (one of prostate cancer and two of other diseases).

CONCLUSIONS: A substantial proportion of patients with unfavorable-risk localized prostate cancer achieved long-term disease control with estramustine and vinblastine and concurrent 3D-CRT, no significant long-term toxicities were seen and 48% underwent no further therapy after RT. These long-term findings support the continued study of chemotherapy combined with RT as a potential alternative to prolonged androgen deprivation.
