Many protocols for treatment of superficial bladder cancer include periodic cystoscopic examinations with resection of visible lesions. This allows pathological restaging of the disease at each examination. For example, this type of follow-up is common in clinical trials evaluating intravesical therapies. In such trials, clinical outcome is typically summarized using end-points that measure failure to control superficial disease. Alternative endpoints measuring failure to prevent progression to invasive disease are often ignored. In this report, the rationale for ignoring the invasive disease endpoints is given and flaws in the rationale are described. Evidence from actual data sets support the view that superficial disease endpoints may not be appropriate surrogates for invasive disease endpoints. It is recommended that time to invasive disease should be considered a major endpoint when designing and analyzing trials in superficial bladder cancer.

BackgroundCD8+ tissue-resident memory T (TRM) cells, marked by CD103 (ITGAE) expression, are thought to actively suppress cancer progression, leading to the hypothesis that their presence in tumors may predict response to immunotherapy.MethodsHere, we test this by combining high-dimensional single-cell modalities with bulk tumor transcriptomics from 1868 patients enrolled in lung and bladder cancer clinical trials of atezolizumab (anti-programmed cell death ligand 1 (PD-L1)).ResultsITGAE was identified as the most significantly upregulated gene in inflamed tumors. Tumor CD103+ CD8+ TRM cells exhibited a complex phenotype defined by the expression of checkpoint regulators, cytotoxic proteins, and increased clonal expansion.ConclusionsOur analyses indeed demonstrate that the presence of CD103+ CD8+ TRM cells, quantified by tracking intratumoral CD103 expression, can predict treatment outcome, suggesting that patients who respond to PD-1/PD-L1 blockade are those who exhibit an ongoing antitumor T-cell response.

The Authors present their experience with TUR plus adjuvant intravesical chemotherapy in 50 patients affected by primary T1 G3 bladder tumours without previous or concomitant carcinoma in situ. At a mean follow-up of 36 months, 84% of the patients are alive and tumour-free. Cystectomy was performed in three patients due to locally invasive disease. Five patients (10%) died of bladder cancer.

Although superficial bladder cancer may be considered “benign”, it is still today a many-sided neoplasm with a prognosis that cannot be well-defined with known traditional parameters. Proliferation indices Ki67 and AgNOR associated with the expression of some oncogenes (p53, Rb, c-myc, BCL2, c-erbB-2) in relation to traditional parameters could help in the prognosis definition of individual patients. 111 patients with superficial bladder cancer were studied for this purpose, relating the grade, stage, follow-up and morphotype to the proliferation indices. Significant correlations were found with AgNOR, but only for grade with Ki67. The study of the oncoproteins and their different expression showed that those alterations typical of infiltration are already present in the superficial forms, with a significant correlation between oncogenic alterations and grade and stage of disease (p53, Rb) on the one hand, and above all of disease-free interval and progression (c-erbB-2) on the other. Lastly, assessment of the oncoproteins c-myc and BCL2, oncogenes connected with the programmed cell death mechanism (apoptosis), showed important correlations with the neoplastic progression of disease in relation to the p53 expression and proliferative activity.

512 Background: Standard management of high risk TCC is either BCG or radical cystectomy, alternative treatment options are limited. It is known that the anti-tumor effect of heated mitomycin is 10 fold higher than at room temperature, which is the standard of intravesical therapy. We herein report the first 2 year follow up (FU) after intravesical therapy with heated mitomycin in a cohort of patients with high risk superficial bladder cancer (TCC). Methods: Treatment was performed for 1 hour with machine bladder irrigation (COMBAT) which maintaines temperature of mitomycin (40 mg) exactly at 43 C. Patients underwent therapy with a 6 week course of weekly treatment and were than followed by cystoscopy every 3 month and if necessary biopsy. Results: We identified 62 patients out of a total group of 108 patients who met the inclusion criteria for high risk TCC according to the EAU Guidelines and who got the complete 6 courses of treatment. 2 were lost of follow up, 1 died due to cardiac problems and 1 from metastatic prostate carcinoma. The remaining 58 patients had a mean FU of 26 month (16-54 m) and included 20 non-responders to BCG. 48/58 patients had CIS or pT1 Tumors or both, 10 patients had pTa+CIS. There were 5 recurrences, all superficial stage pTa, one in the rigth ureter, all could be managed without cystectomy. 8 patients had progressive or recurrent CIS/pT1 or were progressive to pT2 after therapy and underwent cystectomy. Conclusions: In this high risk cohort of 58 patients with a high rate of BCG non-responders only 8 patients had to undergo cystectomy during a 2 year follow up. Intravesical therapy with heated mitomycin is safe and well tolerated and may be an additional alternative treatment before cystectomy is performed in high risk patients with high risk TCC or BCG non responders.
