Alkylating agents, such as streptozocin and dacarbazine, have been reported as active in neuroendocrine neoplasms (NENs). Temozolomide (TMZ) is an oral, potentially less toxic derivative of dacarbazine, which has shown activity both as a single agent and in combination with other drugs. Nevertheless, its role in NENs has not been well defined. Several retrospective and prospective phase I-II st...
The addition of B-cell lymphoma 2 (Bcl-2) antisense to dacarbazine in the treatment of metastatic melanoma demonstrates improved response rates and progression-free survival when compared with dacarbazine alone. Studies on small cohorts of melanoma patients have shown variability in Bcl-2 expression (60%-96% positive). We performed quantitative analysis of Bcl-2 expression in a large patient co...
In vitro tests of tumor cell drug sensitivity have been suggested as a means of selecting more appropriate clinical strategies against human cancer and improving preclinical drug development. The lack of biotransformation in these in vitro assays precludes the meaningful assessment of several major chemotherapeutic agents, including dacarbazine and cyclophosphamide. In vivo drug exposure of tum...
The U.S. Food and Drug Administration recently approved vemurafenib for the treatment of BRAF valine in exon 15, at codon 600 (V600E) mutant metastatic melanoma. Vemurafenib is a competitive small-molecule serine-threonine kinase inhibitor that functions by binding to the ATP-binding domain of mutant BRAF. Compared with dacarbazine chemotherapy, vemurafenib significantly improved the 6-month ov...
Hodgkin lymphoma (HL) is a lymphoproliferative disease arising in the lymphoid tissue, which is characterized by Reed–Sternberg cells. Adenocarcinoma is the most frequent pathological type of stomach cancer. Improved survival in HL patients leads to the development of secondary malignancies. However, synchronous occurrence of these 2 malignancies is extremely rare. Here, we present a 45-year-ol...
On August 17, 2011, the U.S. Food and Drug Administration (FDA) approved vemurafenib tablets (Zelboraf, Hoffmann-LaRoche Inc.) for the treatment of patients with unresectable or metastatic melanoma with the BRAF(V600E) mutation as detected by an FDA-approved test. The cobas 4800 BRAF V600 Mutation Test (Roche Molecular Systems, Inc.) was approved concurrently. An international, multicenter, ran...
Cancer including melanoma may be ''addicted" to double strand break (DSB) repair and targeting this process could sensitize them to the lethal effect of DNA damage. PARP1 exerts an important impact on DSB repair as it binds to both single- and double- strand breaks. PARP1 inhibitors might be highly effective drugs triggering synthetic lethality in patients whose tumors have germline or somatic ...
Glutathione disulfide (GSSG) is an endogenous peptide and the oxidized form of glutathione. The impacts of GSSG on cell function/dysfunction remain largely unexplored due to a lack of method to specifically increase intracellular GSSG. We recently developed GSSG liposomes that can specifically increase intracellular GSSG. The increase affected 3 of the 4 essential steps (cell detachment, migrat...
