简要总结

This is a randomized multicentre study in patients with high-risk MIBC to investigate adjuvant radiotherapy after radical cystectomy and pelvic lymph node dissection.

The objective of the study is to provide evidence that adjuvant radiotherapy improves loco-regional control with potential benefits in survival. The study will also evaluate the quality of life of patients and the tolerance of the treatment.

详细描述

INDICATION:

Patients with pathological high-risk muscle invasive bladder cancer treated by radical cystectomy and pelvic lymph nodes dissection

METHODOLOGY:

Multicenter randomised phase II study in high-risk bladder cancer patients treated by radical cystectomy with pelvic lymph nodes dissection assessing :

  • Experimental Arm: adjuvant pelvic radiotherapy consisting of 28 x 1.8 Gy fractions (total dose of 50.4 Gy), 5 days per week, 1 fraction /day (duration of RT is 38 days).
  • Standard Arm: surveillance. Eligible patients will be randomised, in a 3:1 ratio, to receive either: adjuvant pelvic radiotherapy (Experimental Arm), or surveillance (Standard Arm).

入选标准

  • To be eligible, the patients must fulfil all of the following inclusion criteria:
  • Patients with histologically-confirmed muscle-invasive bladder cancer, either with pure urothelial carcinomas, or dominant urothelial carcinomas (>50%) combined with other histological variants including: micropapillary, epidermoid, or adenocarcinomas, are eligible. Patients with small cell variants, pure adenocarcinomas, or pure epidermoid carcinomas are not eligible.
  • Patients with radical cystectomy and pelvic lymph nodes dissection with no microscopic residual disease (R0 and R1).
  • Note that only R1 patients without urinary diversion as orthotropic neo-bladder replacement are eligible for the study, to limit cystectomy bed radiation induced toxicities.
  • Patients with tumours of TNM staging: pN0-2, M0 by imagery, and pT3a, pT3b, pT4a, and pT4b, as well as, pTX-pN1-2, pTX-NX-R1 are eligible.
  • Patients having received neo-adjuvant or adjuvant chemotherapy treatment are eligible. Randomization is allowed only if AE due to chemotherapy are ≤grade 2 at randomization.
  • Patients ≥18 years old.
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤
  • Absolute neutrophil count (ANC) ≥1500 cells/mm³.
  • Platelets ≥100000 cells/mm³.
  • Haemoglobin ≥8 g/dL (Note: following a blood transfusion or another intervention if required).
  • Adequate hepatic function: aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) ≤2.5 x upper limit of normal (ULN); or ≤3.5 x ULN in the case of concurrent disease with known etiology and for which a corrective treatment is possible.
  • Adequate renal function: clearance >30 mL/min (MDRD).
  • Patients having provided written informed consent prior to any study-related procedures.
  • Patients affiliated to the social security scheme.
  • Patients willing and able to comply with the scheduled visits, treatment plan, laboratory tests, and other study procedures indicated in the protocol.

排除标准

  • Patient must not be enrolled if he/she fulfils any of the following non-inclusion criteria:
  • Patients with R1 resection and with orthotropic neo-bladder reconstruction as urinary diversion are not eligible.
  • Patients with clinical or radiological evidence of metastases or N3 staged bladder cancer are not eligible.
  • Prior invasive solid tumours or haematological malignancies unless disease free for a minimum of 3 years prior to randomisation except:
  • skin basal cell carcinoma,
  • in situ epithelioma of the cervix,
  • or prostate cancer: incidentally discovered during cystoprostatectomy and pelvic lymph node dissection and with a good prognosis (T stage <pT3b and/or Gleason <8 and pN- and/or post-operative prostate-specific antigen (PSA) <0.1 nanogram/mL),
  • Prior pelvic radiotherapy.
  • Patients with active inflammatory bowel disease.
  • Patients who required surgical treatment for bowel obstruction before bladder cancer diagnosis or after cystectomy.
  • Prior chemotherapy for other malignant diseases within the previous 5 years, except for neoadjuvant pre-cystectomy chemotherapy or adjuvant chemotherapy which are permitted.
  • Patients with the following severe acute co-morbidity are not eligible:
  • Unstable angina or congestive heart failure that required hospitalization in the 6 months before randomisation.
  • Transmural myocardial infarction in the 6 months prior to randomisation.
  • Acute bacterial or fungal infection requiring intravenous antibiotics at randomisation.
  • Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of randomisation.
  • Severe hepatic disease: Child-Pugh Class B or C hepatic disease.
  • Known acquired immune deficiency syndrome (AIDS); the study treatment could impact blood count.
  • Patients with any other disease or illness which requires hospitalization or is incompatible with the study treatment are not eligible.
  • Patients unable to comply with study obligations for geographic, social, or physical reasons, or who are unable to understand the purpose and procedures of the study.
  • Patients enrolled in another therapeutic study within 30 days prior of randomisation.
  • Person deprived of their liberty or under protective custody or guardianship.

结局指标

主要结局

pelvic recurrence-free survival (PRFS)

时间窗: 3 years

The PRFS is defined as the delay between randomization and pelvic recurrence or death, whichever occurs first. The pelvic recurrence will be evaluated according to RECIST V1.1 criteria.

次要结局

  • Overall Survival (OS)(5 years)
  • Disease-free survival (DFS)(5 years)
  • pelvic recurrence-free survival (PRFS)(5 years)
  • Metastasis-free survival (MFS)(5 years)
  • Disease-specific survival (DSS)(5 years)
  • Patients' quality of Life(5 years)
  • Patient quality of Life(5 years)
  • Tolerance will be evaluated by toxicity: acute (<6 months after RT) and late (≥6 months after RT), assessed using the NCI CTCAE Version N°4.0(5 years)
  • Evaluation of acute and late toxicities(5 years)
