Objective: Downstaging by neoadjuvant chemotherapy improves the survival of patients with muscle-invasive bladder cancer. In salvage setting, gemcitabine plus cisplatin has demonstrated an efficacy similar to that of methotrexate, vinblastine, doxorubicin and cisplatin with less toxicity. Therefore, the application of neoadjuvant gemcitabine plus cisplatin is also being anticipated.
Methods: Twenty-two patients who received neoadjuvant gemcitabine plus cisplatin were evaluated. The rate of downstaging, chemotherapy delivery profile and toxicity data were assessed. As comparator group, nine patients who were administered with neoadjuvant methotrexate, vinblastine, doxorubicin and cisplatin were evaluated.
Results: A mean of 1.9 cycles of neoadjuvant gemcitabine plus cisplatin were performed. Achieved drug intensity for gemcitabine and cisplatin was 83.8 and 95.4%. Downstaging to pT0 and
Conclusions: The rate of downstaging by neoadjuvant gemcitabine plus cisplatin was comparable with that by methotrexate, vinblastine, doxorubicin and cisplatin. Gemcitabine plus cisplatin was associated with less non-hematologic toxicity than methotrexate, vinblastine, doxorubicin and cisplatin.

The recent clinical outcomes of multi-regimen chemotherapy included prolonged survival and a high rate of conversion to surgery in Asian patients with advanced biliary tract cancer. The ability of single-operator cholangioscopy (SOC) to detect and stage extrahepatic cholangiocarcinoma (CCC) in intraductal lesions is becoming more important in determining the extent of surgery. The aim of this study was to evaluate the role of SOC in surgical planning for extrahepatic CCC.

Research into the role of probiotics-often referred to as "living supplements"-in cancer therapy is still in its early stages, and uncertainties regarding their effectiveness remain. Relevantly, chemopreventive and therapeutic effects of probiotics have been determined. There is also substantial evidence supporting their potential in cancer treatment such as immunotherapy.

Drug-induced hyponatremia is an adverse reaction with accelerated electrolyte disturbance. This study reported a rare case of delayed hyponatremia in a 68year-old female with recurrent upper tract urothelial carcinoma after Gemcitabine plus Cisplatin (GC) and Tislelizumab treatment. She had left ureter surgery, recurrence a year later with mildly abnormal kidney function (glomerular filtration rate (GFR) was 54.

Biliary tract cancers (BTCs), including gallbladder and bile duct cancers, have a poor prognosis. Recent advances in chemotherapy, such as using targeted drugs for specific gene mutations, have improved outcomes. Gemcitabine plus cisplatin chemotherapy has been the standard of care for the primary treatment of BTCs, but secondary treatment had not been established until recently.

Historically, the standard of care for advanced biliary tract cancers (aBTCs) was gemcitabine plus cisplatin (GemCis). Immunotherapy plus GemCis is now recommended as a first-line treatment for aBTCs. Whether patients can tolerate eight cycles of GemCis in clinical practice, as per the Advanced Biliary Cancer (ABC)-02 study, remains to be assessed.
