Advanced cancer responds clinically to combined therapy with recombinant interferon-alpha and 5-fluorouracil. Although the two agents may interact in the biosynthetic pathway for thymidine, we investigated, as an alternative mechanism, the regulation of susceptibility of the A375 human melanoma to natural killers activated by interferon. A375 were preincubated with 5-fluorouracil, interferon, o...

OBJECTIVE Owing to the risks of serious and sustained toxicity, anticancer drugs such as cisplatin and irinotecan cannot be readily administered to patients with gastric cancer and severe peritoneal metastasis. Therefore, a standard chemotherapy regimen has yet to be established for these types of patients. This randomized study investigated the utility of sequential methotrexate and 5-fluorour...

Purpose: To investigate the efficacy of cisplatin and fluorouracil chemotherapy in combination with Jianpi Yiqi formula treatment advanced gastric cancer.Methods: A total 64 patients cancer admitted treated at Xianyang Central Hospital from April 2019 to October 2021 were recruited assigned equally group according time admission. Chemotherapy received fluorouracil, while based on given group. S...

Modulation of pyrimidine metabolism or the metabolic fate of 5-fluorouracil by a number of different agents has permitted a significant increase in the response rate to this agent, particularly for colorectal cancers. Brequinar, a noncompetitive inhibitor of mitochondrial dihydroorotate dehydrogenase has been shown to achieve a tumor-specific modulation of the therapeutic effect of 5-fluorourac...

background: melanoma progression and metastasis is suggested to be mediated by increased accumulation of myeloid derived suppressor cells. various chemotherapeutic drugs such as 5-fluorouracil in single low concentration have the capacity, at least in part, to reverse tumor progression by reducing myeloid derived suppressor cellsmediated immunosuppression. objective: to assess whether multiple ...

Cholesterol-conjugated 5-fluorouracil prodrugs were designed to be carried in vivo via low density lipoproteins (LDL) and subsequently undergo LDL-receptor-mediated internalisation into cancer cells. In vivo anti-cancer evaluation was performed using 5-fluorouracil-cholesterol conjugate in a mouse model. The obtained prodrugs were more potent than 5-fluorouracil control drug at the same 5-fluor...

Although 5-fluorouracil induces relatively minimal thrombocytopenia in mice compared with antiplatelet serum, the ensuing rebound thrombocytosis is much greater. It also occurs several days later. Administration of 5-fluorouracil 24 hr after antiplatelet serum suppresses the increase in platelets produced by antiplatelet serum while the subsequent thrombocytosis is indistinguishable from that p...

Advanced cancer responds clinically to combined therapy with recom binant interferon-a and 5-fluorouracil. Although the two agents may interact in the biosynthetic pathway for thymidine, we investigated, as an alternative mechanism, the regulation of susceptibility of the A375 human melanoma to natural killers activated by Interferon. A375 were preincubated with 5-fluorouracil, Interferon, or b...
