BACKGROUND: Docetaxel in combination with cisplatin and 5-fluorouracil (5-FU) is one of several standard chemotherapy regimens for patients with advanced gastro-esophageal adenocarcinoma (aGEA) in Europe. To enable outpatient treatment, we evaluated the maximum tolerated dose (MTD), recommended dose (RD), dose limiting toxicity (DLT) and safety of docetaxel in combination with oxaliplatin (O) and S-1 (DOS) in Caucasian patients with aGEA. METHODS: We present final results of two parallel phase 1/2a studies (3 + 3 design)...

Primary squamous cell carcinoma of the pancreas (SCCP) is a rare neoplasm, given a lack of naturally occurring squamous cells within the pancreas, accounting for only 0.2% of all pancreatic cancers. The etiology is unknown. Symptomatology is non-specific and similar to other pancreatic neoplasms. No non-invasive testing can adequately rule in SCCP, and workup should proceed similarly to any pancreatic mass. Tissue sampling is required for diagnosis and guidance of further management, most commonly by endoscopic ultrasound with fine needle aspirate...

INTRODUCTION: Upfront surgeries are not beneficial to most patients with pancreatic cancer. Therefore, more emphasis has been placed chemoradiotherapy in locally advanced pancreatic cancer recently. Gemcitabine-based regimens or FOLFIRINOX (a chemotherapy regimen including leucovorin, 5-FU, irinotecan, oxaliplatin) has been proven as a standard chemotherapy in pancreatic cancer. However, severe toxicities may prevent the completion of chemotherapy. S-1 has showed better objective response rates, similar overall survival rates and progression-free survival rates compared with gemcitabine, revealing that S-1 may be a potential candidate in treating pancreatic cancer, especially for patients refractory to gemcitabine...

BACKGROUND: Neoadjuvant chemotherapy for resectable advanced esophageal squamous cell carcinoma (ESCC) requires reassessment. We have conducted a trial aiming at the comparison between DCF and ACF concerning perioperative adverse events. METHODS: Patients were randomly assigned to receive either DCF [docetaxel 70 mg/m2, cisplatin 70 mg/m2 on day 1, and 5-fluorouracil (5-FU) 700 mg/m2 for 5 days] every 3 weeks or ACF (adriamycin 35 mg/m2, cisplatin 70 mg/m2 on day 1, and 5-FU 700 mg/m2 for 7 days) every 4 weeks...

At present, there is no specific anti-metastasis drug in HCC treatment. Drugs used for primary HCC tumors and tumor metastasis are very similar, among which cytotoxic drugs are prevalent, such as cisplatin, doxorubicin and 5-FU. The EGFR pathway plays an important role in promoting hepatocellular carcinoma (HCC) metastasis. Hence, development of non-toxic anti-metastasis drugs, such as EGFR or downstream pathways inhibitors, is of great importance. In our present study, we found non-toxic dose of liposomal honokiol (LH) could inhibit the HCC metastasis by destabilizing EGFR and inhibiting the downstream pathways...

Multidrug resistance (MDR) is a major obstacle in the effective chemotherapeutic treatment of cancers. Triptolide (TPL) is a diterpenoid isolated from Tripterygium wilfordii Hook. f., a traditional Chinese medicine. It was demonstrated in our previous study that TPL exerts anti-MDR cancers on various MDR cell lines (including A549/Taxol, MCF-7/ADR and Bel7402/5-Fu). The present study was designed to investigate its anti-proliferative activity on A549/Taxol cells, and explore the underlying mechanism of action...

Thymidine phosphorylase (TP) is structurally similar to platelet-derived endothelial cell growth factor, and it activates 5-fluorouracil (5-FU) prodrugs and also promotes angiogenesis. In the present study, the possibility of using TP expression as a biomarker for 5-FU prodrugs, and the significance of TP as an angiogenic factor, were investigated in patients with gynecological tumors. The subjects enrolled in the study were 188 patients with gynecological tumors who provided informed consent and underwent tumor resection at the Department of Obstetrics and Gynecology of Tokai University Hospital between February 2002 and January 2010...

Hepatocellular carcinoma(HCC)with severe vascular invasion has a dismal prognosis, and there is no well-established effective therapy. We report an 84-year-old man who benefited from multiple transcatheter arterial chemoembolization (TACE)treatments for advanced HCC with severe vascular invasion. Initial CT revealed a recurrent, poorly differentiated HCC with tumor thrombus in the inferior vena cava(IVC)and right atrium(Vv3). Two cycles of TACE with 5-FU, DOC, MMC, and superabsorbent polymer microspheres(SAP-MS)with BV resulted in considerable reduction of the tumor thrombus...

BACKGROUND: Locally advanced unresectable pancreatic cancer (LAPC) historically portends a poor prognosis. FOLFIRINOX and gemcitabine/nab-paclitaxel have proven effective in the metastatic setting. We sought to evaluate the outcomes of these regimens compared with older regimens in LAPC. METHODS: A retrospective, single institutional review of all consecutive LAPC treated with "new" (FOLFIRINOX and/or gemcitabine/nab-paclitaxel) and "old" (gemcitabine or 5-FU) chemotherapy from 2010 to 2014 was performed...

Cancer stem cells (CSCs) are a key target for reducing tumor growth, metastasis, and recurrence. Redox status is a critical factor in the maintenance of CSCs, and the antioxidant enzyme Peroxiredoxin 2 (Prdx2) plays an important role in the development of colon cancer. Therefore, we investigated the contribution of Prdx2 to the maintenance of stemness of colon CSCs. Here, we used short-hairpin RNAs and a Prdx2-overexpression vector to determine the effects of Prdx2. We demonstrated that knockdown of Prdx2 reduced the self-renewal and sphere formation and resulted in increased 5-FU-induced apoptosis in human colon CSCs...

Gastric cancer is one of the most common malignant diseases, and poses a serious threat to the quality of human life. Gastric cancer stem/progenitor cells (GCSPCs) have critical effects on tumor formation, affecting specific features of self-renewal and differentiation and playing a critical role in metastasis. The Notch-1 pathway is crucially important to GCSPCs and is regulated by DLL4. In this study, DLL4 and Nestin levels were measured in 383 gastric cancer tissue samples by immunohistochemistry, and the clinico-pathological features of patients assessed...

Colon cancer is a leading cause of cancer-related death in humans. 5-Fluorouracil (5-FU), a major chemotherapy treatment, has been used for decades to fight numerous types of cancers, including breast, colon, and head and neck carcinomas. Unfortunately, a large proportion of patients treated with 5-FU develop toxicities that include diarrhea, mucositis, neutropenia, and vomiting. While the side effects of 5-FU are well known, the mechanisms underlying the induction of these unpleasant symptoms are poorly understood...
