Immunogenic Cell Death as a Novel Mechanism of Mitomycin C Activity in Bladder Cancer (ICH-MIM-01)
調査の概要

詳細な説明
Urothelial or transitional cell carcinoma of the bladder is the fourth most common cancer in males worldwide, with about 60-80% of newly diagnosed patients having non-muscle-invasive bladder cancer (NMIBC). NMIBC management consist in transurethral resection of bladder tumor (TURBT) followed by adjuvant intravesical treatment with the chemotherapeutic agent Mitomycin C (MMC) or the immunotherapy bacillus Calmette-Guérin. These therapies result in low progression rates, but are not efficacious in all patients, leading to high tumor recurrence. Immunogenic cell death (ICD) may be one of the mechanisms of action of MMC intravesical therapy in bladder cancer.
The primary objective of the study is to evaluate whether MMC is able to trigger ICD in patient-derived neoplastic tissues. As secondary targets we aim to:
- identify an expression profile that is common to all tumors that undergo ICD upon MMC treatment ('ICD signature'),
- asses the genetic and environmental factors- urinary microbiome composition- responsible for MMC treatment efficacy,
- evaluate whether ICD induction correlates with clinical staging and response (clinical endpoints for MMC-treated patients are recurrence at three month and one year after enrollment).

調査対象母集団
80 patients with carcinoma of the bladder; divided in 20 patients Ta (low grade), 20 patients Ta/T1 (high grade) and 20 patients T2. Only for liquid samples collection we will include 20 CIS (carcinoma in situ) patients.
30 age and sex-matched subjects not suffering from carcinoma of the bladder, already hospitalized in ICH; we expect to enroll 24 males and 6 females of which 10 of 40- 60 years old, 10 of 60-70 years old, 10 of >70 years old.

ONLY for controls:
- Treated with immunomodulatory agents at time of enrollment or in the two months before enrollment

Bladder cancer patients

|
urine collection: DNA is isolated from urine samples (catheterized, washout, midstream) and the 16S rRNA gene is sequenced. Specimen collection: Specimens collected during TURBT are selected by a pathologist and trasferred to the laboratory. The tissues are treated ex vivo with MMC. |
