Effects of pretreatment transurethral resection on survival in prostatic carcinoma.
The survival of 117 patients with carcinoma of the prostate treated with radiation at SUNY-Health Science Center at Brooklyn and Kings County Hospital Center was analyzed according to their pretreatment method of diagnosis. Sixty-four patients (54.7%) underwent a transurethral resection of the prostate (TURP) for obstructive symptoms prior to definitive therapy, while 53 patients (45.3%) were diagnosed with needle biopsy. The overall 5-year survival rate was 46% in the needle biopsy group and 38% in the TURP group. Black and white patients with high Gleason scores (7 to 10) and black patients with low-grade tumors who underwent TURP had an adverse 5-year survival rate compared with those patients diagnosed by needle biopsy. The 5-year survival rate of patients with high Gleason scores comparing needle and TURP was 37% versus 16%. The 5-year survival rate of black patients with low-grade tumors comparing needle biopsy versus TURP was 50% and 22%, respectively, although not statistically significant because of the small sample size. When evaluated by stage, there was no difference in survival rates of TURP versus needle biopsy. Black patients who underwent TURP had a 28% 5-year survival rate compared with a 44% 5-year survival rate in white TURP patients. This analysis reveals that black and white patients with high-grade tumors and black patients, even with low-grade tumors, may have a lower survival rate if they undergo TURP prior to radiation, but this may be due to higher stage and larger volume disease in these patients.
