BACKGROUND Standard treatment for osteosarcoma patients consists of a combination of cisplatin, adriamycin, and methotrexate before surgical resection of the primary tumour, followed by postoperative chemotherapy including vincristine and cyclophosphamide. Unfortunately, many patients still relapse or suffer adverse events. We examined whether common(More)
Hereditary pheochromocytoma (PCC) is often caused by germline mutations in one of nine susceptibility genes described to date, but there are familial cases without mutations in these known genes. We sequenced the exomes of three unrelated individuals with hereditary PCC (cases) and identified mutations in MAX, the MYC associated factor X gene. Absence of(More)
Platinum agents cause DNA cross-linking. Nucleotide excision repair genes play a key role in DNA damage repair. This study aims to investigate whether polymorphisms in these genes are associated with tumor response and survival in cisplatin-treated osteosarcoma patients. Eight single nucleotide polymorphisms in ERCC2, XPC, XPA, ERCC1, ERCC4 and ERCC5 genes(More)
Vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMP) regulate each other, contributing to tumor progression. We have previously reported that MMP9 induces the release of tumor VEGF, promoting ascites formation in human ovarian carcinoma xenografts. The aim of this study was to investigate whether tumor-derived VEGF regulated the(More)
PURPOSE Hand-foot syndrome (HFS) is one of the most relevant dose-limiting adverse effects of capecitabine, an oral prodrug of 5-fluorouracil used in the standard treatment of breast and colorectal cancer. We investigated the association between grade 3 HFS and genetic variations in genes involved in capecitabine metabolism. EXPERIMENTAL DESIGN We(More)
BACKGROUND The approved capecitabine regimen as monotherapy in metastatic breast cancer (MBC) is 1,250 mg/m(2) twice daily for 2 weeks on and 1 week off (Cint). Dose modifications are often required because of severe hand-foot syndrome (HFS). We tested a continuous regimen with a lower daily dose but a similar cumulative dose in an attempt to reduce the(More)
Purpose: Hand-foot syndrome (HFS) is one of the most relevant dose-limiting adverse effects of capecitabine, an oral prodrug of 5-fluorouracil used in the standard treatment of breast and colorectal cancer. We investigated the association between grade 3 HFS and genetic variations in genes involved in capecitabine metabolism. Experimental Design: We(More)
1008 Background: X, 1,250 mg/m2 bid, d1-14 q21d (Xint) is an approved regimen in MBC, but is associated with dose-limiting toxicities. Thus, we designed this randomized phase II study to investigate whether continuous dosing of X (Xcont) could reduce the severity of side effects while maintaining the total cumulative dose and efficacy. METHODS Pts with(More)
