Clinical Trial Summary

Aim and objectives: This trial aims to evaluate the role of adjuvant radiotherapy following chemotherapy in patients with high-risk features on histo-pathology after radical surgery for transitional cell carcinoma of urinary bladder


Description:

Treatment details: Surgery(Standard/routine care) All patients would have undergone radical surgery in the form of a cysto-prostatectomy and pelvic nodal dissection as part of their standard care. Patients would also have a urinary diversion (Ileostomy) or a continent neo bladder. Chemotherapy All patients following cysto-prostatectomy will receive upto 4 cycles of adjuvant chemotherapy if medically fit for the same. Those patients who received neoadjuvant chemotherapy, will receive additional chemotherapy cycle after surgery to a total of 4 cycles if found suitable. The chemotherapy regimen, doses and schedule will be as per standard institutional practice using Platinum based chemotherapy. No concomitant chemotherapy with radiotherapy is recommended. Radiation therapy: All patients will be treated with conformal radiotherapy technique with intensity modulated radiotherapy with or without image guidance. The radiotherapy will start within maximum of 8 weeks from the date of surgery if adjuvant chemotherapy has not been planned. If adjuvant chemo planned the patients will receive radiotherapy within 4 weeks of the last chemo cycle. Dose Prescription: 50.4Gray (Gy) in 28fractions (1.8Gy/#) will be prescribed for the nodal PTV. In case of R1 and/or R2 resection dose to the pelvic nodes and tumour bed may be increased to 54-56Gy in 28 fractions depending on the constraints achieved during planning. Clinical assessment: 1. Toxicity will be assessed by 1. Weekly physician assessment during RT with scoring of toxicity. 2. RTOG toxicity criteria at baseline, 6-8 weeks post RT and at 3 monthly thereafter for 2 years and 6 monthly thereafter for 5 years. 3. QOL will be assessed at baseline and 3-6 monthly thereafter 2. Disease evaluation The first follow up all patients will be done at 6-8 week to assess toxicity. Clinical evaluation of the disease will be done at each follow up visits by clinical examination. CT scan of the abdomen and pelvis will be done 6 monthly from second visit onwards up to 2 years and 12 monthly thereafter or whenever clinically indicated as decided by the physician.

Intervention

Other:
Adjuvant RT
Radiation therapy: All patients will be offered conformal technique with IMRT +/- image guidance. The adjuvant RT will start within 8 weeks from the date of surgery if chemotherapy not planned or 4 weeks from the date of last adjuvant chemo cycle. Dose: •50.4 Gray (Gy) in 28 fractions (1.8Gy/#) for the nodal PTV. For R1 and/or R2 resection increased to 54-56 Gy in 28 fractions based on the constraints achieved during planning. Patient assessments: Clinical: Toxicity: Weekly RT with toxicity scoring. RTOG toxicity criteria at baseline, 6-8 weeks post RT and f/b 3 monthly x 2 years and 6 monthly x 5 years. QOL will be assessed at baseline f/b 3-6 monthly. Disease evaluation: i. first f/u all patients will be at 6-8 week to assess toxicity. ii. Clinical evaluation of the disease will be done at each f/u visit. iii. CT scan (abdomen and pelvis) 6 monthly from visit 2 onwards up to 2 years f/b 12 monthly or as clinically indicated.
