Abstract
BACKGROUND:The standard of care treatment approach for Muscle invasive bladder cancer (MIBC) at present is Radical Cystectomy. Organ preservation treatment is offered to patients with MIBC who are either not considered for surgery or patients who refuse surgical management. With this study we wanted to assess the clinical outcome of MIBC patients treated with organ preservation approach.
METODOLOGY:This was a retrospective including MIBC patients treated at our centre with definitive raditherapy/ Chemoradiation.
RESULTS:Details of 18 patients were analysed. Majority of patients in our study were smokers (83%), males (94%) and had T3 as tumor stage. The most common histology was Urothelial carcinoma. Commonest RT schedule used was 60 Gy in 30 fractions (33%). Concurrent chemotherapy was given in six patients (33%). Only three patients (17%) had acute Grade 3 toxicity. Median OS in our study was 45 months. OS at 1 year,2 years and 5 years were 81.4%, 62.8% and 41.9% respectively. Median PFS of patients in this study was 39 months. PFS at 1 year,2 years,4 years were 69.8%, 59.9% and 44.9% respectively.
CONCLUSION: Our study showed that organ preservation approach for MIBC is a well tolerated treatment approach. PFS and OS in our study were slightly lesser compared to available literature. This could be due to the higher proportion of Stage III patients in our study and fewer patients receiving concurrent chemotherapy due to multiple factors like multiple comorbidities and older age. Retrospective nature of study and the lesser number of patients are the limitations of this study.
