The N-demethylation of dacarbazine in liver microsomes was significantly increased by treatment of rats with b-naphthoflavone, dexamethasone, or phenobarbital. However, the extent of increase in the N-demethylation observed in b-naphthoflavone-treated rats was much greater than that observed in dexamethasone-treated rats. A good correlation between N-demethylation of dacarbazine and O-deethylat...
BACKGROUND Dabrafenib, an inhibitor of mutated BRAF, has clinical activity with a manageable safety profile in studies of phase 1 and 2 in patients with BRAF(V600)-mutated metastatic melanoma. We studied the efficacy of dabrafenib in patients with BRAF(V600E)-mutated metastatic melanoma. METHODS We enrolled patients in this open-label phase 3 trial between Dec 23, 2010, and Sept 1, 2011. This...
Renal epithelioid angiomyolipoma (REA) is a rare mesenchymal tumor. The primary choice of treatment is local treatments. There is no consensus about adjuvant treatment. Doxorubicine, dacarbazine, ifosfamide, cyclophosphamide and cisplatin were shown to be effective in some case reports We present a metastatic renal epithelioid angiomyolipoma case that was treated with doxorubicin in the first l...
O(6)-Methylguanine and O(6)-chloroethylguanine, which are the primary cytotoxic DNA lesions produced by 5-(3,3-dimethyl-1-triazeno)imidazole-4-carboxamide (dacarbazine) and 1-(4-amino-2-methyl-5-pyrimidinyl)methyl-3-(2-chloroethyl)-3-nitrosourea (ACNU), respectively, can be repaired by O(6)-methylguanine-DNA methyltransferase (MGMT), coded by the MGMT gene. However, the two types of drugs exhib...
Melanoma is a tumour derived from melanocytes, cells of neuroectodermal origin. Melanoma treatment represents a challenge to oncologists due to its aggressive course and early and multiple metastases. Surgical excision of lesions is a highly effective intervention, but only in early stages. In contrast, median survival of patients with metastatic melanoma is still below one year. In 2011 the FD...
BACKGROUND Phase 1 and 2 clinical trials of the BRAF kinase inhibitor vemurafenib (PLX4032) have shown response rates of more than 50% in patients with metastatic melanoma with the BRAF V600E mutation. METHODS We conducted a phase 3 randomized clinical trial comparing vemurafenib with dacarbazine in 675 patients with previously untreated, metastatic melanoma with the BRAF V600E mutation. Pati...
BACKGROUND Malignant melanoma is a highly aggressive malignant melanocytic neoplasm which resists against the most conventional therapies. Sea cucumber as one of marine organisms contains bioactive compounds such as polysaccharide, terpenoid and other metabolites which have anti-cancer, anti-tumor, anti-inflammatory and antioxidant properties. The present study was designed to investigate the a...
PURPOSE The development of effective therapeutic approaches for treatment of metastatic melanoma remains an immense challenge. Present therapies offer minimal benefit. Although dacarbazine chemotherapy remains the standard therapy, it mediates only low response rates, usually of short duration, even when combined with other chemotherapeutic agents. Thus, new therapeutic strategies are urgently ...
BACKGROUND The importance of immune responses in the control of melanoma growth is well known. However, the implication of these antitumor immune responses in the efficacy of dacarbazine, a cytotoxic drug classically used in the treatment of melanoma, remains poorly understood in humans. METHODS In this prospective observational study, we performed an immunomonitoring of eleven metastatic or ...
We describe a randomized three-arm phase I study of ipilimumab administered alone (I group) or in combination with dacarbazine (D group) or carboplatin/paclitaxel (CP group) in patients with previously untreated advanced melanoma. The primary objective was to estimate the effect of ipilimumab on the pharmacokinetics (PK) of dacarbazine and paclitaxel and, conversely, to estimate the effects of ...
