Prognostic factors and risk groups in T1G3 non-muscle-invasive bladder cancer patients initially treated with bacillus Calmette-Guérin: Results of a retrospective multicenter study of 2451 patients - Abstract

BACKGROUND: The impact of prognostic factors in T1G3 non-muscle-invasive bladder cancer (BCa) patients is critical for proper treatment decision making.

OBJECTIVE: To assess prognostic factors in patients who received bacillus Calmette-Guérin (BCG) as initial intravesical treatment of T1G3 tumors and to identify a subgroup of high-risk patients who should be considered for more aggressive treatment.

DESIGN, SETTING, AND PARTICIPANTS: Individual patient data were collected for 2451 T1G3 patients from 23 centers who received BCG between 1990 and 2011.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Using Cox multivariable regression, the prognostic importance of several clinical variables was assessed for time to recurrence, progression, BCa-specific survival, and overall survival (OS).

RESULTS AND LIMITATIONS: With a median follow-up of 5.2 yr, 465 patients (19%) progressed, 509 (21%) underwent cystectomy, and 221 (9%) died because of BCa. In multivariable analyses, the most important prognostic factors for progression were age, tumor size, and concomitant carcinoma in situ (CIS); the most important prognostic factors for BCa-specific survival and OS were age and tumor size. Patients were divided into four risk groups for progression according to the number of adverse factors among age ≥70 yr, size ≥3cm, and presence of CIS. Progression rates at 10 yr ranged from 17% to 52%. BCa-specific death rates at 10 yr were 32% in patients ≥70 yr with tumor size ≥3cm and 13% otherwise.

CONCLUSIONS: T1G3 patients ≥70 yr with tumors ≥3cm and concomitant CIS should be treated more aggressively because of the high risk of progression.
