folinic acid/sarcoma

Normal and Rous sarcoma virus-infected chicken fibroblasts proliferate maximally in a culture medium containing a physiological (10 ng/ml) concentration of 5-methyltetrahydrofolic acid or folinic acid (5-formyltetrahydrofolic acid), while their maximal proliferation requires a hyperphysiological

An 18-year-old female patient receiving adjuvant chemotherapy for osteogenic sarcoma developed a pruritic erythematous rash during infusion of the eighth dose of methotrexate (8 g/m2) in the series. In other respects, the infusion proceeded normally but the 24-hour serum concentration of

OBJECTIVE Aggressive chemotherapy protocols for non-metastatic limb osteosarcoma have improved histological response without affecting prognosis. This study evaluated the toxicity and outcome of a dose-intensive, high-dose 3- to 5-drug pilot protocol, SCOS 89. METHODS The cohort included 26 patients

OBJECTIVE Cetuximab shows activity in KRAS (Kirsten rat sarcoma viral oncogene homolog) wild-type metastatic colorectal cancer (mCRC). Recent studies have demonstrated that cetuximab induces antibody-dependent cell-mediated cytotoxicity (ADCC) in mCRC. We investigated the associations of FcγR

A 32-year-old man developed multiple pulmonary metastases from a giant cell tumor of bone. His metastases failed to respond to several chemotherapy regimens (high-dose methotrexate with folinic acid plus doxorubicin 90 mg/m2; cyclophosphamide + bleomycin + actinomycin D; mitoxantrone + dacarbazine;

BACKGROUND Kirsten rat sarcoma virus (KRAS) wild-type status determined using a locked nucleic acid (LNA)-mediated quantitative polymerase chain reaction (qPCR) clamping assay (LNA assay) predicted response to therapy in the CRYSTAL (Cetuximab Combined With Irinotecan in First-Line Therapy for

BACKGROUND In the NORDIC-7.5 trial, how cetuximab might safely and conveniently be added to an intermittent treatment strategy in patients with prospectively selected Kirsten rat sarcoma viral oncogene homolog wild type (KRASwt) metastatic colorectal cancer (mCRC) was investigated. Patients were

The pharmacokinetics of 8 g/m2 methotrexate (MTX) was compared following short (6 h) and long (24 h) infusions of the drug to 11 children with osteogenic sarcoma (OS; 42 infusion) and 28 children with acute lymphoblastic leukemia (ALL: 118 infusions), respectively. No difference was observed in the

A 62-year-old man presented with concurrent sigmoid colon adenocarcinoma and small bowel mesenteric dedifferentiated liposarcoma. Following surgical resection of the colon cancer, complete excision of the mesenteric sarcoma and adjuvant folinic acid, fluorouracil and oxaliplatin (FOLFOX)

The current study aimed to determine the association between protein kinase Cα (PKCα) and Kirsten rat sarcoma viral oncogene homolog (KRAS) expression and the response to folinic acid, 5-fluorouracil and oxaliplatin (FOLFOX regimen) in patients with colorectal cancer (CRC). The protein levels of

The lipophilic diaminopyridopyrimidine BW 301U (2,4-diamino-6-(2,5-dimethoxybenzyl)-5-methylpyrido[2,3-d]pyrimidine) is as active as methotrexate as an inhibitor of dihydrofolate reductase and mammalian cell growth. This compound was selected from among related pyridopyrimidines and other

A conjugate of methotrexate-substituted human serum albumin (HSA) coupled to a monoclonal antibody (791T/36) recognizing osteogenic sarcoma cell lines has been reported previously to have good cytotoxicity and specificity in vitro (Garnett et al., 1983). Cytotoxicity was assessed by the median

Pancreatic metastasis from colorectal cancer is rare, and accounts for less than 2% of all pancreatic metastases. There have been no studies that have reported the differences in the sensitivity to chemotherapy between the primary lesion and the pancreatic metastasis in colorectal cancer. We

A 29-year-old patient presented with bilateral pulmonary lesions following surgery for recurrent placental site trophoblastic tumor (PSTT). On day seven after institution of the 'EMA' regimen (etoposide, medium dose methotrexate with folinic acid rescue and actinomycin-D), complete pneumothorax

BACKGROUND Combination therapies with cetuximab (Erbitux®; Merck Serono UK Ltd) and panitumumab (Vectibix®; Amgen UK Ltd) are shown to be less effective in adults with metastatic colorectal cancer who have mutations in exons 2, 3 and 4 of KRAS and NRAS oncogenes from the rat sarcoma (RAS)
