Background Intravesical Bacillus Calmette-Guérin (BCG) remains the standard adjuvant treatment for non-muscle invasive bladder cancer (NMIBC) following transurethral resection; however, BCG failure and related toxicities are common. Objectives To compare the efficacy and toxicity of intravesical BCG and gemcitabine in the treatment of NMIBC. Methods Retrospective data were collected in the ...

Many studies have demonstrated that emodin inhibits the growth and induces the apoptosis and chemosensitization of various cancer cells in animal models. The aim of this study was to investigate the molecular mechanism of the chemo-sensitization potential of emodin on gemcitabine in pancreatic cancer cell lines via inhibition of nuclear factor-κB (nF-κB). SW1990 and SW1990/GZ cells were treated...

OBJECTIVE To analyze the efficacy of gemcitabine with or without erlotinib for pancreatic cancer, and to determine the predictive role of epidermal growth factor receptor (EGFR) and KRAS mutations in these patients. METHODS This was a single-center, randomized, open-label, prospective trial. Eighty-eight chemotherapy-naïve metastatic pancreatic cancer patients were randomized for treatment wi...

We examined the effects of gemcitabine, a novel nucleotide analogue, and vinorelbine, a semi-synthetic vinca alcaloid, in C6 glioma cell culture. We simultaneously monitored the modulation of its activity in combination with the telomerase inhibitory agent dimetilsülfoxid and with a specific cyclooxygenase-2 inhibitory agent Rofecoxib. The effects of the gemcitabine/ vinorelbine combination wer...

Gemcitabine is a commonly used chemotherapeutic agent for advanced biliary tract carcinoma (BTC), although its efficacy is insufficient. Therefore, it is essential to establish new diagnostic methods, which can predict responders before the treatment. The aim of this study is to identify the most reliable chemoresistance marker to gemcitabine in BTC among the 4 molecules (hENT1, dCK, RRM1 and R...

PURPOSE p21-activated kinases (PAKs) are involved in cytoskeletal reorganization, gene transcription, cell proliferation and survival, and oncogenic transformation. Therefore, we hypothesized that PAK expression levels could predict the sensitivity of pancreatic cancer cells to gemcitabine treatment, and PAKs could be therapeutic targets. MATERIALS AND METHODS Cell viability inhibition by gem...

BACKGROUND Angiosarcoma is a highly aggressive soft tissue sarcoma. Responses to anthracyclines plus/minus ifosfamide, and taxanes alone or in combination with gemcitabine are well documented. Very few data are available on gemcitabine as a single agent. PATIENTS AND METHODS We retrospectively reviewed all cases of advanced progressive angiosarcoma treated with gemcitabine as a single agent (...

As the standard therapy for pancreatic cancer, gemcitabine shows limited efficacy in pancreatic cancer patients because of chemoresistance. Aberrant expression of Bmi1 has been reported to activate multiple growth-regulatory pathways and confer anti-apoptotic abilities to many cancer cells. However, the role of Bmi1 in response of pancreatic cancer cells towards gemcitabine resistance remains e...

Standard first-line chemotherapy regimens in advanced non-small-cell lung cancer (NSCLC) include carboplatin (Paraplatin)/paclitaxel, cisplatin/docetaxel (Taxotere), cisplatin/gemcitabine (Gemzar), and cisplatin/vinorelbine (Navelbine). An informal meta-analysis of 13 randomized trials of these regimens in NSCLC indicates no marked differences in terms of response rates or survival, but toxicit...

BACKGROUND Previous studies of the gemcitabine-pemetrexed combination in patients with late-stage non-small-cell lung cancer (NSCLC) utilized a 90-min delay between gemcitabine and pemetrexed administration. This phase II study evaluated activity when these agents were administered in rapid succession. MATERIALS AND METHODS Chemonaive patients with late-stage NSCLC received gemcitabine 1250 m...
