Prognostic factors and risk groups in T1G3 non-muscle-invasive bladder cancer patients initially treated with Bacillus Calmette-Guerin: results of a retrospective multicenter study of 2451 patients

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 ≥ 3 cm, 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 ≥ 3 cm and 13% otherwise. CONCLUSIONS T1G3 patients ≥ 70 yr with tumors ≥ 3 cm and concomitant CIS should be treated more aggressively because of the high risk of progression. PATIENT SUMMARY Although the majority of T1G3 patients can be safely treated with intravesical bacillus Calmette-Guérin, there is a subgroup of T1G3 patients with age ≥ 70 yr, tumor size ≥ 3 cm, and concomitant CIS who have a high risk of progression and thus require aggressive treatment.

Systematic review of lower urinary tract symptoms/benign prostatic hyperplasia surgical treatments on men's ejaculatory function: Time for a bespoke approach?

Although ejaculatory dysfunction is common for patients undergoing benign prostatic hyperplasia surgery, no clear evidence is present to counsel men seeking to preserve ejaculation. Our aim was to evaluate ejaculatory dysfunction in relation to benign prostatic hyperplasia surgery. We carried out a web and manual search using MEDLINE and Embase including randomized controlled trials reporting ejaculatory dysfunction after benign prostatic hyperplasia surgery: 42 randomized controlled trials comprising a total of 3857 patients were included. Only one study had ejaculatory dysfunction as a primary outcome, and just 10 evaluated ejaculatory dysfunction before and after surgery. The definition of ejaculatory dysfunction was not standardized. Similarly, just seven studies used internationally validated questionnaires to address ejaculatory dysfunction. The reported rates of ejaculatory dysfunction after resectional elecrosurgery, laser procedures, coagulation, ablation and implant techniques were assessed and compared. Transurethral resection of the prostate and recent laser procedures including holmium, thulium and GreenLight cause similar rates of ejaculatory dysfunction, occurring in almost three out of four to five men. Although providing less symptomatic benefit compared with transurethral resection of the prostate, transurethral incision of the prostate, transurethral needle ablation and transurethral microwave thermotherapy should be considered for men aiming to maintain normal ejaculation. UroLift is also a recent promising option for this category of patients. The vast majority of studies reporting ejaculatory dysfunction after benign prostatic hyperplasia surgery used poor methodology to investigate this complication. Future studies able to address clear hypothesis and considering ejaculatory dysfunction anatomical and pathophysiological features are required to develop ejaculation preserving techniques and to increase the evidence to counsel men aiming to preserve ejaculation.

The impact of re-transurethral resection on clinical outcomes in a large multicentre cohort of patients with T1 high-grade/Grade 3 bladder cancer treated with bacille Calmette-Guerin

To determine if a re‐transurethral resection (TUR), in the presence or absence of muscle at the first TUR in patients with T1‐high grade (HG)/Grade 3 (G3) bladder cancer, makes a difference in recurrence, progression, cancer specific (CSS) and overall survival (OS).

A randomized double-blind placebo controlled phase I-II study on clinical and molecular effects of dietary supplements in men with precancerous prostatic lesions. Chemoprevention or "chemopromotion"?

Antioxidants effectiveness in prostate cancer (PCa) chemoprevention has been severely questioned, especially after the recent results of the Selenium and Vitamin E Cancer Prevention Trial. We present the results of a double‐blind randomized controlled trial (dbRCT) on the pharmacokinetic, clinical, and molecular activity of dietary supplements containing lycopene, selenium, and green tea catechins (GTCs) in men with multifocal high grade prostatic intraepithelial neoplasia (mHGPIN) and/or atypical small acinar proliferation (ASAP).

The Impact of Intravesical Gemcitabine and 1/3 Dose Bacillus Calmette-Guérin Instillation Therapy on the Quality of Life in Patients with Nonmuscle Invasive Bladder Cancer: Results of a Prospective, Randomized, Phase II Trial

PURPOSE Bacillus Calmette-Guérin and intravesical chemotherapy represent viable adjuvant options for intermediate risk nonmuscle invasive bladder cancer. Although bacillus Calmette-Guérin is perceived as less tolerable than intravesical chemotherapy, to our knowledge no comparative studies have addressed quality of life issues. We compared the quality of life of patients with nonmuscle invasive bladder cancer who received adjuvant intravesical gemcitabine or 1/3 dose bacillus Calmette-Guérin. MATERIALS AND METHODS Our multicenter, prospective, randomized, phase II study included 120 patients with intermediate risk nonmuscle invasive bladder cancer. Of these patients 88 remained assessable at 1-year followup. Only 1 patient was withdrawn because of adverse events. Overall 61 patients received 2,000 mg/50 cc gemcitabine weekly for 6 weeks (maintenance monthly for 1 year) while 59 received 1/3 dose bacillus Calmette-Guérin Connaught weekly for 6 weeks (maintenance 3 weekly instillations at 3, 6 and 12 months). Quality of life was measured by the EORTC QLQ-C30 (European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 version 3.0) and QLQ-BLS24 (Quality of Life Superficial Bladder Cancer-Specific 24) questionnaires. Group differences were calculated using ANOVA (ANOVA/MANOVA). RESULTS Treatment was well tolerated in both groups, although local and systemic side effects were more frequently reported in the bacillus Calmette-Guérin arm. Multivariate analyses showed no significant differences between the 2 groups in all quality of life dimensions. No significant changes over time in quality of life domains were detected for patients on bacillus Calmette-Guérin and gemcitabine except for physical functioning, which decreased significantly in both groups (p = 0.002). No significant differences were detected in terms of recurrence and progression between the 2 groups at 1-year followup. CONCLUSIONS While a higher rate of side effects, albeit mild to moderate, was detected with 1/3 dose bacillus Calmette-Guérin compared to gemcitabine, our study failed to show significant differences between the 2 drugs in terms of quality of life.

Prognostic Factors of ‘High-Grade' Ta Bladder Cancers according to the WHO 2004 Classification: Are These Equivalent to ‘High-Risk' Non-Muscle-Invasive Bladder Cancer?

Objective: To determine the impact of prognostic factors of a series of high-grade Ta non-muscle-invasive bladder cancers (NMIBCs) according to the new International Society of Urological Pathology (ISUP) 1998/WHO 2004 grading system (previously classified as either TaG2 or TaG3). Methods: One hundred and thirty-one high-grade Ta (105 G2 and 26 G3) cases were identified after independent review by two pathologists. Univariable and multivariable Cox regression models addressed recurrence and progression-free survival. Progression was defined as appearance of any T ≥1 recurrence after complete TUR (type 1) or occurrence of T ≥2 (type 2). Results: Ten-year recurrence, type-1 and type-2 progression-free survival were 60, 75 and 95%, respectively. The previous grading system (G3 vs. G2) significantly predicted type 1 progression in the univariate model only. In the multivariate model, Ki67 was the only independent predictor of progression according to both definitions (HR = 5.25, p = 0.002 and HR = 6.16, p = 0.03, respectively). Conclusions: High-grade Ta NMIBC as defined by the WHO 2004 grading system cannot be equated with high-risk NMIBC. The risk of progression to muscle-invasive disease (type 2) is low, more in keeping with an intermediate-risk category of NMIBC. The previous WHO 1973 subcategorization into G2 and G3 is of little help in the prediction of outcome. Ki67 is a strong independent predictor of progression worthy of consideration for a clinical setting.

Prognostic Factors Including Ki-67 and p53 in Bacillus Calmette-Guérin-Treated Non-Muscle-Invasive Bladder Cancer: A Prospective Study

Objectives: To prospectively evaluate the prognostic utility of the traditional prognostic factors and molecular markers p53 and Ki-67 in a homogeneous series of patients with non-muscle-invasive bladder cancer (NMIBC) treated with Bacillus Calmette-Guérin (BCG). Patients and Methods: 192 intermediate- and high-risk NMIBC cases were enrolled. The variables in study were age, stage, grade, focality, tumour size, presence of associated carcinoma in situ, recurrence rate before BCG, maintenance for BCG, Ki-67 and p53. The endpoints considered were recurrence-free survival, progression-free survival, cancer-specific survival (CSS) and overall survival (OS). Results: T stage resulted in being associated with CSS, whereas age with OS. BCG maintenance was a significantly favourable independent predictor of OS, CSS, recurrence and progression. In univariate analysis, the labelling index of Ki-67 was significantly associated with OS, CSS and progression. Multivariate analysis, however, confirmed this association only for OS. On the contrary, the labelling index of p53 was a significant predictor of recurrence, both in uni- and multivariate analyses, but with a HR inferior to 1. Conclusions: Ki-67 was an independent predictor of survival. p53 overexpression showed a significant yet inverse correlation with recurrence, thus showing little clinical utility. Age, stage and maintenance were confirmed as independent predictors of BCG response.
