Multicenter Study Clinical TrialBreakthrough pain management using fentanyl buccal tablet (FBT) in combination with around-the-clock (ATC) opioids based on the efficacy and safety of FBT, and its relationship with ATC opioids: results from an open-label, multi-center study in Japanese cancer patients with detailed evaluation.
Rapid analgesic onset opioids, particularly fentanyl buccal tablet, is preferable for managing breakthrough pain. The efficacy and safety of fentanyl buccal tablet and its association with around-the-clock opioids needs to be explored with an option of dose adjustments, more closely reflecting administration in clinical practice. The aim of the study was to assess the safety and efficacy of fentanyl buccal tablet in breakthrough pain management in combination with around-the-clock opioids with the dose adjustment option, and explore the dose adjustment's influence on breakthrough pain management using detailed evaluation. ⋯ Fentanyl buccal tablet can stably and safely manage breakthrough pain in cancer patients with independent dose adjustment based on detailed evaluation of each patient's condition. Breakthrough pain management using fentanyl buccal tablet with around-the-clock opioids at optimal doses may be an important factor in palliative care for cancer patients with breakthrough pain.

Randomized Controlled Trial Comparative StudyRandomized controlled trial comparing docetaxel-cisplatin combination with weekly docetaxel alone in elderly patients with advanced non-small-cell lung cancer: Japan Clinical Oncology Group (JCOG) 0207†.
Prospective trials specifically designed for elderly patients with advanced non-small-cell lung cancer demonstrating the benefit of platinum-based therapies are still lacking. This trial was designed to clarify whether the addition of cisplatin to monotherapy could improve survival for elderly patients. ⋯ The interpretation of study results is limited due to early stopping. Further study is needed to confirm survival benefit of platinum-based chemotherapy for elderly non-small-cell lung cancer [UMIN-CTR (www.umin.ac.jp/ctr/) ID: C000000146].

Phase I and pharmacokinetic study of trastuzumab emtansine in Japanese patients with HER2-positive metastatic breast cancer.
Trastuzumab emtansine (T-DM1), an antibody-drug conjugate composed of the cytotoxic agent DM1 conjugated to trastuzumab via a stable thioether linker, has shown clinical activity in human epidermal growth factor receptor 2-positive metastatic breast cancer patients. This study evaluated the maximum tolerated dose, toxicity and pharmacokinetics of trastuzumab emtansine in Japanese breast cancer patients. ⋯ Trastuzumab emtansine up to 3.6 mg/kg was well tolerated by Japanese breast cancer patients. Although thrombocytopenia and hepatotoxicity tended to be more severe than was seen in Western patients in previous trastuzumab emtansine trials, those adverse events recovered without special supportive treatment.
