Summary
Radical cystectomy offers better survival for bladder adenocarcinoma than segmental resection. However, bladder dome tumors may be exceptions, with segmental resection showing comparable survival to total cystectomy.
Area of Science:
- Urologic Oncology
- Surgical Pathology
- Cancer Treatment Outcomes
Background:
- Pure primary adenocarcinoma of the bladder is a rare malignancy.
- Patients often present with hematuria, irritative voiding symptoms, or obstruction.
- Lesions are frequently high-grade, invasive, and located at the bladder dome.
Purpose of the Study:
- To evaluate treatment outcomes for primary bladder adenocarcinoma.
- To compare the efficacy of radical cystectomy versus segmental resection.
- To investigate the unique behavior of bladder dome adenocarcinoma.
Main Methods:
- Retrospective analysis of 25 patients with pure primary bladder adenocarcinoma.
- Treatment modalities included transurethral resection, radiotherapy, segmental resection, and radical cystectomy.
- Five-year survival rates were compared across different treatment groups and lesion locations.
Main Results:
- Radical cystectomy demonstrated a nearly twofold increase in five-year survival compared to segmental resection.
- Transurethral resection was primarily diagnostic and palliative; radiotherapy showed limited value.
- Bladder dome lesions, potentially urachal remnants, exhibited different behavior, with segmental resection yielding survival rates similar to total cystectomy.
Conclusions:
- Radical cystectomy is generally superior for treating primary bladder adenocarcinoma.
- Segmental resection may be a viable alternative for solitary bladder dome adenocarcinomas.
- Further research into urachal remnant tumors is warranted.
