Abstract Background Urothelial bladder carcinoma accounts for around 3.9% cases of all the male cancers in India. Non-muscle-invasive bladder carcinoma (NMIBC) is predominant group which constitute approximately three fourth of the urothelial bladder cancer. Intravesical BCG immunotherapy is the corner stone of today’s NMIBC management. However, as with any other therapy it has its own complications and its interruption due to these adverse effects is a major cause of suboptimal efficacy. The aim of this study was to assess the complications of intravesical BCG therapy and their management in NMIBC patients. Methods This was a retrospective descriptive study conducted between October 2016 and November 2019; a backward review of 149 patients with diagnosis of NMIBC that undergone intravesicle BCG therapy was performed. Patient’s demographical, clinical, diagnostic and procedural data regarding bladder tumour, BCG therapy, its complications and management were collected and analysed. Results Total 149 patients were analysed, comprising 116 males and 33 females. The mean age was of 57.2 ± 6.7 years. Total 85.23% were primary and 14.76% were recurrent tumours. Total 96 patients (64.42%) completed the planned course, while 53 (35.57%) interrupted. The reasons for BCG interruption includes adverse effects (15.4%), progression of disease (6.7%), disease refractory to BCG (4.6%) and disease recurrence during BCG (3.3%). Most of the adverse events occurred in first 6 months and most interruptions occurred after the induction period. Cystitis was the most common observed adverse effect seen in 39.6% patients. Frequency, urgency, haematuria were common presentation. Radical cystectomy was the most common (16.10%) further treatment with patients whose treatment was interrupted. Conclusion BCG is an indispensable therapy available for NMIBC, but it is associated with array of adverse effects and complications, which are the main reasons for poor compliance to BCG therapy. Although BCG-related complications can affect any organ in the body, potentially life-threatening systemic BCG-related infections are encountered in only < 5% of patients. There are some difficulties in diagnosis of the BCG complications because acid-fast staining, culture and PCR test are not always positive; tissue biopsies should be indicated sometimes to evaluate histopathology and presence of M. bovis. A persistently monitored multidisciplinary approach with high index of suspicion and prompt anti-TB therapy can help to derive the maximum benefits while keeping the complications at check.

BackgroundAlthough intravesical BCG is the standard treatment of high-grade non-muscle invasive bladder cancer (NMIBC), response rates remain unsatisfactory. In preclinical models, rapamycin enhances BCG vaccine efficacy against tuberculosis and the killing capacity of γδ T cells, which are critical for BCG’s antitumor effects. Here, we monitored immunity, safety, and tolerability of rapamycin combined with BCG in patients with NMIBC.MethodsA randomized double-blind trial of oral rapamycin (0.5 or 2.0 mg daily) versus placebo for 1 month was conducted in patients with NMIBC concurrently receiving 3 weekly BCG instillations (NCT02753309). The primary outcome was induction of BCG-specific γδ T cells, measured as a percentage change from baseline. Post-BCG urinary cytokines and immune cells were examined as surrogates for local immune response in the bladder. Secondary outcomes measured were adverse events (AEs) and tolerability using validated patient-reported questionnaires.ResultsThirty-one patients were randomized (11 placebo, 8 rapamycin 2.0 mg, and 12 rapamycin 0.5 mg). AEs were similar across groups and most were grade 1–2. One (12.5%) patient randomized to 2.0 mg rapamycin was taken off treatment due to stomatitis. No significant differences in urinary symptoms, bowel function, or bother were observed between groups. The median (IQR) percentage change in BCG-specific γδ T cells from baseline per group was as follows: −26% (−51% to 24%) for placebo, 9.6% (−59% to 117%) for rapamycin 0.5 mg (versus placebo, p=0.18), and 78.8% (−31% to 115%) for rapamycin 2.0 mg (versus placebo, p=0.03). BCG-induced cytokines showed a progressive increase in IL-8 (p=0.02) and TNF-α (p=0.04) over time for patients on rapamycin 2.0 mg, whereas patients receiving placebo had no significant change in urinary cytokines. Compared with placebo, patients receiving 2.0 mg rapamycin had increased urinary γδ T cells at the first week of BCG (p=0.02).ConclusionsFour weeks of 0.5 and 2.0 mg oral rapamycin daily is safe and tolerable in combination with BCG for patients with NMIBC. Rapamycin enhances BCG-specific γδ T cell immunity and boosts urinary cytokines during BCG treatment. Further study is needed to determine long-term rapamycin safety, tolerability and effects on BCG efficacy.

BACKGROUND: In patients with non-invasive urothelial carcinoma of the prostatic urethra (PUC), treatment with Bacillus Calmette-Guárin (BCG) could be beneficial. OBJECTIVE: To assess the response rates to BCG in the different tumor stages, to describe the clinical impact of transurethral resection of the prostate (TURP) before BCG treatment, and to review the side effects of BCG treatment for PUC. METHODS: A systematic search was conducted using the PubMed database to identify original studies between 1977 and 2019 reporting on PUC and BCG. RESULTS: Of a total of 865 studies, ten were considered for evidence synthesis. An indication for BCG treatment was found in non-stromal invasive stages (Tis pu, Tis pd) and in stromal infiltrating cases (T1) of primary and secondary PUC when transitional cell carcinoma was the histology of origin. Studies including patients treated with TURP before BCG showed a better local response in the prostatic urethra with a higher DFS (80–100% vs. 63–89%) and PFS (90–100% vs. 75–94%) than patients in studies in which no TURP was performed. However, this difference in recurrence and progression in the prostate neither affected the total PFS (57–75% vs. 58–93%), nor the disease specific survival (70–100% vs. 66–100%). CONCLUSIONS: The use of resection loop biopsies of the prostatic urethra in appropriate cases during the primary work-up for suspected PUC, as well as the use of the current TNM classification for PUC, need to be improved. BCG therapy for non-stromal invasive stages of PUC show a good local response. Local response is further improved by a TURP before BCG therapy, although the overall prognosis does not seem to be affected. Further evidence for BCG treatment in the rare cases of stromal invasive PUC is needed. Specific side effects of BCG treatment for PUC are not reported.

BACKGROUND: The optimal management of non-invasive (mucosal and/or ductal) urothelial carcinoma of the prostate remains elusive and there is a paucity of data to guide treatment. OBJECTIVE: Our objective was to systematically review and synthesize treatment responses to conservative management of non-invasive prostatic urothelial carcinoma using intravesical therapy. METHODS: A systematic literature search using MEDLINE, EMBASE, Cochrane Library, SCOPUS, and Web of Science databases from inception to November 2019 was performed. Risk of bias assessment was performed using the Newcastle-Ottawa scale for non-randomised studies. Pooled estimates of complete response in the bladder and prostate and prostate only were performed using a random effects model. Pre-specified subgroup analyses were generated to assess differences in complete responses for: BCG therapy vs other agents, ductal vs mucosal involvement, CIS vs papillary tumors and TURP vs no TURP. RESULTS: Nine studies including 175 patients were identified for inclusion in the systematic review and meta-analysis. All were retrospective case series and most evaluated response to BCG therapy. The pooled global complete response rate for intravesical therapy was 60%(95%CI: 0.48, 0.72), and for prostate 88%(95%CI: 0.81, 0.96). Pre-specified analyses did not demonstrate statistically significant differences between subgroups of interest. CONCLUSIONS: Management of non-invasive prostatic urothelial carcinoma using intravesical therapy yields satisfactory results. Caution should be taken in treating patients with papillary tumors and ductal involvement, as data for these populations is limited. TURP may not improve efficacy, but is required for staging. Current recommendations are based on low quality evidence, and further research is warranted.

456 Background: To evaluate Hyperthermic Intra-Vesical Chemotherapy (HIVEC) efficacy regarding 1-year disease-free survival (DFS) rate and bladder preservation rate in patients with high-risk Non-Muscle Invasive Bladder Cancer (NMIBC) who fail BCG therapy or are contraindicated to BCG. Methods: Between June 2016 and October 2019, patients treated with HIVEC for high-risk NMIBC who failed BCG (Fail-BCG) or BCG-naive if BCG contraindicated (N-BCG) have been included in our study. These patients had a theoretical indication for cystectomy but were ineligible for surgery or refused it. Results: Fifty-three patients, median age 72 [39-93] years, were included (n = 29 Fail-BCG and n = 24 N-BCG). The median follow-up was 18 months. The bladder preservation rate was 92.4%. The RFS rate at 12 months was 60.5%. The RFS rate at 12 months for N-BCG and Fail-BCG groups was respectively 70% and 52.2%. Three patients progressed to muscle-invasive disease, all in the Fail-BCG group and all in the very high-risk EORTC group. Two of them experienced metastatic progression and died from bladder cancer. Conclusions: Chemohyperthermia using HIVEC device achieved a RFS rate of 60% at 1 year and enabled a bladder preservation rate of 92%. Given the low risk of progression in the N-BCG group, HIVEC could be a good alternative. Conversely, for patients with very high-risk tumors that fail BCG, cystectomy should remain the standard of care and HIVEC may be discussed cautiously for patients who are not eligible for surgery and well informed of the risk of progression to muscle-invasive disease.

This study evaluates a short therapy schedule for bladder cancer using BCG Tokyo. BCG Tokyo was evaluated in vitro using bone marrow derived dendritic cells, neutrophils, RAW macrophages and the murine bladder cancer cell line, MB49PSA, and compared to other BCG strains. BCG Tokyo > BCG TICE at inducing cytokine production. In vivo, high dose (1 × 107 colony forming units (cfu)) and low dose (1 × 106 cfu) BCG Tokyo with and without cytokine genes (GMCSF + IFNα) were evaluated in C57BL/6J mice (n = 12–16 per group) with orthotopically implanted MB49PSA cells. Mice were treated with four instillations of cytokine gene therapy and BCG therapy. Both high dose BCG alone and low dose BCG combined with cytokine gene therapy were similarly effective. In the second part the responsive groups, mice (n = 27) were monitored by urinary PSA analysis for a further 7 weeks after therapy cessation. More mice were cured at day 84 than at day 42 confirming activation of the immune system. Cured mice resisted the re-challenge with subcutaneous tumors unlike naïve, age matched mice. Antigen specific T cells recognizing BCG, HY and PSA were identified. Thus, fewer intravesical instillations, with high dose BCG Tokyo or low dose BCG Tokyo with GMCSF + IFNα gene therapy, can induce effective systemic immunity.
