Currently, only a small fraction of patients with stage IV bladder cancer can be cured and for many patients, the emphasis is on palliation of symptoms. The potential for cure is restricted to patients with stage IV disease with involvement of pelvic organs by direct extension or metastases to regional lymph nodes.
To diagnose bladder cancer, your doctor completes a thorough medical history and examination. You will then be referred to a urologist, a physician who has special training in managing diseases of the bladder.
The first test the urologist may perform is an intravenous pyelogram (IVP), followed by a cystoscopy. During a cystoscopy, the urologist will pass a cystoscope (a fiber-optic lighted tube) through the urethra in order to view the bladder. A urine sample for cytology will be obtained and a...
Standard treatment options for patients with T4b, N0, M0 or any T, N1–N3, M0 disease
Treatment options for patients with T4b, N0, M0 or any T, N1–N3, M0 disease include the following:
Radical cystectomy followed by chemotherapy.
Radical cystectomy alone.
External-beam radiation therapy (EBRT) with or without concomitant chemotherapy.
Urinary diversion or cystectomy for palliation.
Cisplatin-based combination chemotherapy regimens are the standard of care for stage IV bladder cancer.[2,3,4,5,6] The only chemotherapy regimens that have been shown to result in longer survival in randomized controlled trials are methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC); high-dose MVAC; and cisplatin, methotrexate, and vinblastine (CMV). Gemcitabine plus cisplatin (GC) was compared with MVAC in a randomized controlled trial and no difference in response rate or survival was reported. Of note, patients with good performance status and lymph node-only disease have a low but significant rate of achieving a durable complete remission with MVAC or GC. In the large randomized controlled trial that compared MVAC with GC, for example, 5-year overall survival (OS) in patients with lymph node-only disease was 20.9%.
Single-agent cisplatin and multiagent regimens that do not include cisplatin have never been shown to improve survival in a randomized controlled trial. Thus, there is no regimen that has been shown to prolong survival in patients who are not candidates for cisplatin-based multiagent chemotherapy regimens. Many regimens have been shown to be active, however, with regard to producing radiologically measurable responses:
These include carboplatin plus paclitaxel, carboplatin plus gemcitabine,[9,10,11] paclitaxel plus gemcitabine,[12,13,14] single-agent gemcitabine,[15,16] and single-agent paclitaxel.[17,18,19] Regimens of carboplatin, methotrexate, and vinblastine; carboplatin, epirubicin, methotrexate, and vinblastine; and carboplatin, gemcitabine, and carboplatin have been studied but are not widely used.[20,21,22,23]
