Multicenter Study Observational StudyTesting the effectiveness of antiemetic guidelines: results of a prospective registry by the CINV Study Group of Japan.
Many cancer patients suffer from the common side effect of chemotherapy-induced nausea and vomiting (CINV). Guidelines recommend a combination of two prophylactic antiemetics for moderately emetogenic chemotherapy (MEC) and three for highly emetogenic chemotherapy (HEC) and certain MEC regimens. ⋯ Adherence to antiemetic guidelines effectively controls vomiting but is less effective against delayed nausea in HEC and MEC patients. Identification of individual risk factors, such as female sex, will assist in the development of personalized treatments for CINV. More intensive antiemetic therapy or a different modality of prophylaxis should be considered for the control of acute CINV in an anthracycline-cyclophosphamide regimen.

Randomized Controlled TrialRegorafenib for advanced gastrointestinal stromal tumors following imatinib and sunitinib treatment: a subgroup analysis evaluating Japanese patients in the phase III GRID trial.
The randomized, double-blind, placebo-controlled GRID trial tested the oral multikinase inhibitor regorafenib in 199 patients with advanced gastrointestinal stromal tumors (GIST) following failure of at least imatinib and sunitinib, and showed a significant improvement in progression-free survival (PFS) versus placebo [hazard ratio (HR) 0.27; 95 % confidence interval (CI) 0.19-0.39; p < 0.0001]. ⋯ Regorafenib showed efficacy and a manageable safety profile in Japanese patients with advanced GIST, consistent with the overall GRID study population. AEs, such as HFSR and maculopapular rash, were observed more frequently in Japanese patients. Although dose modification was frequently reported, only one patient with hepatic failure discontinued regorafenib because of AEs.

Randomized Controlled TrialEffect of duloxetine in Japanese patients with chemotherapy-induced peripheral neuropathy: a pilot randomized trial.
Chemotherapy-induced peripheral neuropathy (CIPN) is difficult to manage. A phase III trial conducted in the United States demonstrated that duloxetine was effective for CIPN caused by taxane and platinum-based chemotherapy. No randomized trial of duloxetine for CIPN has been conducted in Japan. ⋯ Our data suggests that duloxetine has a beneficial effect on CIPN caused by oxaliplatin, paclitaxel, vincristine, or bortezomib in Japanese patients.
