Importance: Neoadjuvant chemotherapy (NAC) followed by radical cystectomy improves survival compared with cystectomy alone for patients with bladder cancer. Although gemcitabine with cisplatin has become a standard NAC regimen, a dose-dense combination of methotrexate, vinblastine, doxorubicin, and cisplatin (ddMVAC) is being adopted at some institutions. Objective: To assess the association of neoadjuvant ddMVAC vs standard regimens with downstaging and overall survival among patients treated with radical cystectomy for bladder cancer...

Objective: Compared with standard treatment, a modified tri-weekly MVAC (methotrexate, doxorubicin, vinblastine, and cisplatin) treatment regimen with a high cisplatin dose intensity shows good efficacy and lower toxicity. Thus, we retrospectively investigated the tolerability and efficacy of a modified tri-weekly MVAC neoadjuvant regimen. Methods: We analyzed 25 patients with locally advanced bladder cancer medicated by a modified tri-weekly MVAC neoadjuvant regimen that omits treatment on days 15 and 22...

Purpose Neoadjuvant chemotherapy followed by radical cystectomy (RC) is a standard of care for the management of muscle-invasive bladder cancer (MIBC). Dose-dense cisplatin-based regimens have yielded favorable outcomes compared with standard-dose chemotherapy, yet the optimal neoadjuvant regimen remains undefined. We assessed the efficacy and tolerability of six cycles of neoadjuvant dose-dense gemcitabine and cisplatin (ddGC) in patients with MIBC. Patients and Methods In this prospective, multicenter phase II study, patients received ddGC (gemcitabine 2,500 mg/m2 on day 1 and cisplatin 35 mg/m2 on days 1 and 2) every 2 weeks for 6 cycles followed by RC...

BACKGROUND: Approximately half of patients who undergo radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) will succumb to metastatic disease. We summarize the evidence for neoadjuvant radiation (NAR), chemo (NAC), and immunotherapy (checkpoint inhibition) prior to RC for MIBC. MATERIALS AND METHODS: Data were obtained by a search of PubMed, ClinicalTrials.gov, and Cochrane databases for English language articles published from 1925 up to 2017. RESULTS: NAC usage has increased over the last decade, while NAR is rarely administered...

Cystectomy is the gold standard for treatment of localized muscle-invasive bladder cancer. However, about 50% of patients develop metastases within 2years after cystectomy and subsequently die for the disease. Neoadjuvant cisplatin-based chemotherapy before cystectomy improves the overall survival in patients with muscle-invasive bladder cancer, and pathological response to neoadjuvant treatment (downstaging to ⩽pT1 at cystectomy) is a strong predictor of better disease-specific survival. Nevertheless, some patients do not benefit from neoadjuvant therapy...

Many patients diagnosed with muscle-invasive bladder cancer (MIBC) will develop distant metastatic disease. Over the past three decades, perioperative cisplatin-based chemotherapy has been investigated for its ability to reduce the number of deaths from bladder cancer. Insufficient evidence is available to fully support the use of such chemotherapy in the adjuvant setting; however, neoadjuvant cisplatin-based combination chemotherapy has become a standard of care for eligible patients based on the improved disease-specific and overall survival demonstrated in two randomized phase III trials, compared with surgery alone...

Staging of muscle-invasive bladder cancer (MIBC) remains a challenge. It is generally acknowledged that the most commonly used imaging techniques have a trend to either upstage or downstage the disease. The aim of this review article is to evaluate the currently available scientific evidence for the use of imaging modalities in preoperative bladder cancer staging with special attention to the detection of lymph node metastasis (LNM). A non-systematic literature search utilizing PubMed database with terms MIBC and LN and MRI or PET or CT was performed with the search limited to articles published between 2010 and 2015...
