Abstract
In the treatment of cancer patients, cisplatin (CDDP) exhibits serious cardiac and renal toxicities, while classical combinations related to CDDP are unable to solve these problems and may result in worse prognosis. Alternately, this study covalently conjugated 6-mercaptopurine (6MP) onto the surface of mercapto-modified mesoporous silica nanoparticles (MSNS) to form MSNS-6MP and loaded CDDP into the holes on the surface of MSNS-6MP to form MSNS-6MP/CDDP, a tumor-targeting nano-releasing regime for CDDP and 6MP specifically. In the S180 mouse model, the anti-tumor activity and overall survival of MSNS-6MP/CDDP (50 mg·kg−1·day−1, corresponding to 1 mg·kg−1·day−1 of 6MP and 5 mg·kg−1·day−1 of CDDP) were significantly higher than those of CDDP alone (5 mg·kg−1·day−1) or CDDP (5 mg·kg−1·day−1) plus 6MP (1 mg·kg−1·day−1). The assays of serum alanine aminotransferase, aspartate aminotransferase and creatinine, as well as the images of myocardium and kidney histology, support that MSNS-6MP/CDDP is able to completely eliminate liver, kidney and heart toxicities induced by CDDP alone or CDDP plus 6MP.

Abstract
Our objective was to evaluate the role of amifostine as a cytoprotector in patients with solid tumors receiving the myelosuppressive regimen of gemcitabine/cisplatin combination. Patients with advanced solid tumors were randomized to gemcitabine-amifostine-cisplatin (GAP) or gemcitabine-cisplatin (GP) in Cycle 1 (C1) and then were crossed over to the other treatment in Cycle 2 (C2). Amifostine at 740 mg/m2, followed by gemcitabine and cisplatin, were given for 2 consecutive weeks, every 4 weeks. Two GP combinations were studied: G 1000 mg/m2 and P 40 mg/m2 days 1, 8 (high dose), and G 800 mg/m2 and P 30 mg/m2 days 1, 8 (low dose). Forty patients were enrolled. Of the 19 patients treated with high-dose GP, 11 (nine patients GP in C1 and GAP in C2, two patients GAP in C1 and GP in C2) completed 2 cycles of therapy. Of the eight non-evaluable patients, five patients dropped out due to toxicity or refusal after treatment with amifostine in C1. Of the 21 patients treated with low-dose GP, 15 (eight patients GP in C1 and GAP in C2, seven patients GAP in C1 and GP in C2) were likewise evaluable. The incidence of grade 3 or 4 hematologic toxicities was similar for GP and GAP during the first 2 cycles of treatment, and there were no statistically significant differences in mean absolute neutrophil count, hemoglobin level and platelet levels between the cycles in each arm. We conclude that amifostine, at 740 mg/m2, does not lead to less myelosuppression when combined with gemcitabine/cisplatin chemotherapy regimens and may possibly contribute to subjective intolerance.
