A Multicenter Prospective Cohort Study on Monitoring Recurrence of Urothelial Carcinoma Based on Detection of Urinary Microscopic Residual Disease (MRD)

Korábbi kezelés

• Pathology after radical surgery that does not meet the criteria for enrollment;
• does not undergo radical total cystectomy or standard surgical scope;
• receives less than 2 cycles of neoadjuvant therapy;
• does not undergo regular imaging evaluations during preoperative neoadjuvant therapy;
• has no evaluable lesions prior to neoadjuvant therapy;
• predictable inability to meet the regular review at our center within 1 year after surgery;
• disagreement with regularity of receiving imaging (the clinician decides on the content and type of imaging);

Más betegség

  • Cohort II:
• concurrent combination of other active malignant neoplastic disease or a 5-year history of other malignant neoplastic disease history (excluding basal cell carcinoma and cervical carcinoma in situ after active treatment)
  • Cohort III:
• concurrently combines other active malignant neoplastic disease or a history of other malignant neoplastic disease within 5 years (excluding basal cell carcinoma and cervical carcinoma in situ after active treatment).
  • Cohort IV:

• Already definite recurrence or metastasis;
• TUR pathology that does not meet the enrollment criteria;
• predictable inability to meet the regular review at our center within 1 year postoperatively;
• disagreement with regular cystoscopy and/or imaging (the content and type of imaging will be determined by the clinician);

• TUR pathology that does not meet enrollment criteria;
• already has definitively present distant metastases;
• TUR pathology that does not meet the inclusion criteria;
• no pre-treatment imaging at our center;
• residual lesions or metastases that are already clearly present;

• patients ≥18 years of age with full civil capacity at the time of signing the informed consent form;
• patients who provide a urine sample for MRD testing at the time of undergoing postoperative review;
• Pathologic type: required to be a pathologically confirmed uroepithelial tumor with a predominantly urothelial tumor with a primary site in the upper urinary tract (including the renal pelvis and ureters), and permitted to contain no more than 50% squamous differentiation, adenomatous differentiation, or sarcomatoid differentiation and are pT3/4 or any TpN+.
• patients aged ≥18 years at the time of signing the informed consent form with full civil capacity;
• patients who provided a urine sample for central testing when they underwent postoperative review;
• Pathological type: a pathologically confirmed predominantly uroepithelial tumor with a primary site in the bladder is required, and is permitted to contain no more than 50% squamous differentiation, or adenoidal differentiation carcinoma in situ is permitted to be present or only in situ and the pathologic stage may be T1, Ta, or Tis (Cis)
• patients aged ≥18 years at the time of signing the informed consent form with full civil capacity;
• patients providing urine samples for centralized testing prior to each cycle of treatment during neoadjuvant therapy;
• pathology type: a predominantly uroepithelial tumor with a TUR surgical pathology primary site in the bladder is required, and is permitted to contain no more than 50% squamous, adenomatous, or sarcomatoid differentiation (iii) Patients with pathologic stage T2 or MIBC on comprehensive imaging despite pathologic stage T1;
• Radical cystectomy after neoadjuvant therapy, including bladder, prostate, and seminal vesicles in men and bladder and uterus in women;
• lymph node dissection at least to the extent of the standard dissection for bladder cancer (including the area of the common iliac arteries below the bifurcation of the iliac arteries bilaterally and the area between the ipsoas and genitofemoral nerve to the ureter);
• the presence of evaluable lesions on imaging based on RECIST 1.1 criteria prior to neoadjuvant therapy.
• patients aged ≥18 years at the time of signing the informed consent form with full civil capacity;
• patients to provide a urine sample for centralized testing at each review visit;
• pathology type: the TUR surgical pathology is required to be a predominantly urothelial tumor with a primary site in the bladder, and is allowed to contain no more than 50% squamous, adenomatous, or sarcomatous differentiation;
• there should be a centralized imaging to assess a clinical assessment of MIBC prior to TMT treatment;
• patients assessed as clinically CR after undergoing TMT who can continue to retain their bladder and do not require salvage cystotomy.
