Purpose: Oxaliplatin at a dose of 85 mg/m(2) traditionally has been administered over 120 min in the standard FOLFOX (infusional fluorouracil, leucovorin, and oxaliplatin) regimen. CapeOx (capecitabine plus oxaliplatin), in which the dose of oxaliplatin is 130 mg/m(2), has also been infused over 120 min. Maintenance of a prolonged infusion time has been largely based on the concern for a potential hypersensitivity reaction (HSR) if administered too quickly.
Methods: We first performed a retrospective review of our institutional experience to assess whether HSR rates were similar in FOLFOX and CapeOx by using computerized pharmacy records between January 1, 2011, and December 31, 2013. We then instituted a new policy to infuse all nonresearch doses of oxaliplatin at a set rate of 1 mg/m(2)/min (85 mg/m(2) given over 85 min; 68 mg/m(2) over 68 min, etc). The incidence of HSRs with the new infusion rate was actively monitored.
Results: Of 2,097 patients who previously received oxaliplatin over 120 min, 1,936 received a dose of 85 mg/m(2) (± 10%), and 161 received a dose of 130 mg/m(2). The incidence of HSRs in the 85 mg/m(2) group was 11% versus 7% in the 130 mg/m(2) group (P = .13). Then between December 1, 2014, and June 4, 2015, 667 patients received oxaliplatin at a rate of 1 mg/m(2)/min for all doses. The incidence of HSRs in patients treated at this fixed infusion rate was 8%.
Conclusion: Infusing oxaliplatin at a rate of 1 mg/m(2)/min does not increase the rate of HSRs and does not compromise patient safety. This infusion rate is safe for use in routine practice.

Modified gemcitabine, S-1, and leucovorin combination for patients with newly diagnosed locally advanced or metastatic pancreatic adenocarcinoma: A multi-center retrospective study in Taiwan.

Background: In pancreatic cancer, toxicities associated with current chemotherapeutic regimens remain concerning. A modified combination of gemcitabine, S-1, and leucovorin (GSL) was used as the first-line treatment for newly diagnosed locally advanced or metastatic pancreatic adenocarcinoma patients.
Methods: GSL was administered every 2 weeks-intravenous gemcitabine 800 mg/m2 at a fixed-dose rate of 10 mg/m2/min on day 1 and oral S-1 (80-120 mg/day) plus leucovorin 30 mg twice daily on days 1-7.
Associations of Vitamin D with Inter- and Intra-Muscular Adipose Tissue and Insulin Resistance in Women with and without Polycystic Ovary Syndrome.

Low vitamin D and insulin resistance are common in polycystic ovary syndrome (PCOS) and associated with higher inter- and intra-muscular adipose tissue (IMAT). We investigated associations between vitamin D, IMAT and insulin resistance in a cross-sectional study of 40 women with PCOS and 30 women without PCOS, and pre- and post-exercise in a 12-week intervention in 16 overweight participants (10 with PCOS and six without PCOS). A non-classical body mass index (BMI) threshold was used to differentiate lean and overweight women (BMI ≥ 27 kg/m²).

Objective: To evaluate the efficacy and safety of fixed dose rate (FDR) gemcitabine infusion in combination with docetaxel in patients with relapsed/refractory soft tissue sarcoma.
Methods: Clinicopathological data of 28 patients with relapsed/refractory soft tissue sarcoma treated in our hospital from April 2008 to August 2013 were reviewed in this study. The patients received 900 mg/m² gemcitabine with a FDR infusion (10 mg/m²/min) in a total dose of 900 mg/m² on days 1 and 8, and 75 mg/m² docetaxel intravenously over 60 min on day 8 of a 21-day cycle.
Phase II study of low-dose fixed-rate infusion of gemcitabine combined with cisplatin and dexamethasone in resistant non-Hodgkin lymphoma and correlation with Bcl-2 and MDR expression.

This study aims to assess the efficacy of low-dose fixed-rate infusion of gemcitabine, cisplatin and dexamethasone in resistant non-Hodgkin lymphoma (NHL) patients in addition to evaluating the prognostic value of B cell lymphoma 2 (Bcl-2) and multidrug resistant (MDR) expression in this cohort of patients. Patients with relapsed/refractory NHL following at least two chemotherapy regimens were enrolled. They received gemcitabine 800 mg/m2 in fixed infusion rate of 10 mg/m2/min, cisplatin 35 mg/m2 in days 1, 15 and dexamethasone 20 mg days 1-4, 15-18 every 28 day.
