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 prevent bladder cancer, your best bet is to avoid possible carcinogens, or cancer-causing substances. For starters, don't smoke. Eat smoked or cured meats only occasionally and prepare fresh rather than processed foods.
Research also suggests that there is a reduced incidence of bladder cancer among people with adequate vitamin B-6, beta-carotene, and selenium in their diets. If you work around carcinogenic chemicals, follow safety guidelines to avoid undue exposure. And if you feel you may be...
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]
