Background And Objectives: Irinotecan (CPT-11) is metabolized to an active metabolite 7-ethyl-10-hydroxycamptothecin (SN-38) by carboxylesterase (CES). SN-38 is then converted to the inactive metabolite SN-38 glucuronide (SN-38G) by glucuronosyltransferase 1A1 (UGT1A1). Genetic polymorphisms in UGT1A1 have been associated with altered SN-38 pharmacokinetics, which increase the risk of toxicity in patients.

Background/aim: Amino acids are among the most important nutrients for supplying energy and building protein blocks in cancers. L-type amino acid transporter (LAT) 1 is known to play a critical role in cancer growth. We have completed the first-in-human phase I study using the LAT1-specific inhibitor JPH203.

This open-label first-in-human study evaluated JPH203, which is a novel selective L-type amino acid transporter 1 inhibitor. We also evaluated the association between the N-acetyltransferase 2 phenotype and outcomes. Japanese patients with advanced solid tumors received daily intravenous JPH203 treatment for 7 days, followed by a 21-day rest period, at escalating doses of 12-85 mg/m.

Purpose: Patients with RAS-positive tumors respond poorly to chemotherapies and have a few treatment options. Salirasib is an oral RAS inhibitor that competitively blocks the membrane association of RAS proteins. The aim of this phase I multiple-ascending-dose clinical trial was to investigate the safety and pharmacokinetics of Salirasib in Japanese patients with relapsed/refractory solid tumors and to explore its efficacy.

Background: It is important for cancer patients to receive end-of-life care at the desired place.

Objective: To identify issues in selection of place for end-of-life care of cancer patients to realize their optimal survivorship.

Design And Setting: Between September 2015 and January 2016, a questionnaire consisting of 33 items, including end-of-life care place preferences, was administered to cancer patients who attended three university hospitals in Japan.

Background: No standard second-line chemotherapy has been yet established for gemcitabine-refractory biliary tract cancer (BTC).

Patients And Methods: We conducted multivariable Cox regression analysis to examine the prognostic factors for overall survival (OS) in patients who had received gemcitabine-based treatment.

Results: Forty-six patients received second-line chemotherapy.

Background/aim: Vascular endothelial growth factor receptor (VEGFR) has been identified as a treatment target for biliary tract cancer (BTC) and axitinib is a selective inhibitor of vascular endothelial growth factor receptor (VEGFR)-1/2/3. This study was conducted as a preliminary evaluation of the safety and efficacy of axitinib for patients with advanced BTC.

Patients And Methods: Patients refractory to gemcitabine-based regimens were administered axitinib at the dose of 5 mg twice daily.

Background: Gemcitabine (GEM) plus cisplatin (CDDP) chemotherapy has been used worldwide as the standard first-line treatment for advanced biliary tract cancer (BTC). A phase II trial has also suggested promising activity of GEM plus S-1 chemotherapy against advanced BTC. The aim of this study was to evaluate the efficacy and safety of GEM plus S-1 chemotherapy in patients with advanced BTC.

The use of FOLFIRINOX and gemcitabine plus nab-paclitaxel for unresectable pancreatic cancer is currently approved in Japan. Although the efficacies of these regimens were investigated only in patients with metastatic pancreatic cancer, they are also expected to be effective for locally advanced pancreatic cancer. Meanwhile, chemoradiotherapy is recognized as a treatment option for locally advanced pancreatic cancer.

Article Synopsis
  • - Trametinib, a MEK1/MEK2 inhibitor, was tested in a clinical study for safety and efficacy in Japanese cancer patients, with one part assessing trametinib alone and another part assessing it in combination with gemcitabine.
  • - In the solo treatment phase, doses of trametinib were tolerated with some responses but did not reach maximum toxicity; the combo phase saw some responses but was complicated by serious interstitial lung disease in several patients.
  • - Overall, trametinib was found to be tolerable as a single agent, but its combination with gemcitabine presented greater risks, highlighting a need for careful monitoring in this treatment approach.

Purpose: The purpose of this study was to assess the efficacy and safety of fixed dose rate infusion of gemcitabine and S-1 combination therapy (FGS) in patients with gemcitabine (GEM)-refractory pancreatic cancer (PC) and to explore independent variables associated with survival.

Methods: We retrospectively reviewed consecutive patients with GEM-refractory PC who received FGS at our institution from March 2009 to December 2013. GEM was administered by fixed dose rate intravenous infusion of 1,200 mg/m(2) as a 120-min infusion on day 1, and S-1 was administered orally twice a day at a dose of 40 mg/m(2) on days 1-7.
