Multicenter StudyEffectiveness of Tyrosine Kinase Inhibitors in Japanese Patients with Non-small Cell Lung Cancer Harboring Minor Epidermal Growth Factor Receptor Mutations: Results from a Multicenter Retrospective Study (HANSHIN Oncology Group 0212).
Non-small cell lung cancer (NSCLC) with minor mutations in the epidermal growth factor receptor (EGFR) gene, except for the common 15 base-pair deletions in exon 19 and the L858R mutation in exon 21, is rare, and only few data exist on this patient population. The aim of the present study was to describe the clinical characteristics and to clarify the efficacy of EGFR-tyrosine kinase inhibitors (TKIs) in patients with NSCLC harboring minor mutations of the EGFR gene. ⋯ Patients with NSCLC harboring minor mutations of the EGFR gene exhibited a modest response to EGFR-TKI treatment. Treatment with first-generation EGFR-TKIs, in particular erlotinib, may be considered a first- or second-line option for patients with NSCLC with minor EGFR mutations.

Case ReportsCurative Resection After Gemcitabine, Cisplatin and S-1 Chemotherapy for Initially Unresectable Biliary Duct Cancer: A Case Report.
A 68-year-old woman was diagnosed with unresectable upper bile duct cancer with suspected invasion of the right hepatic artery and para-aortic lymph node metastasis (T4N3M0, stage IVb). She underwent plastic stent placement for obstructive jaundice and enrolled in our phase I study for unresectable biliary tract cancer consisting of cisplatin (25 mg/m(2) i.v. for 120 min) followed by gemcitabine (1,000 mg/m(2) i.v. for 30 min) on days 1 and 8, and oral S-1 on alternate days. ⋯ The pathological stage was pT1N0M0, stage I. The patient made a satisfactory recovery, was discharged 29 days after operation, and remains free of disease at 3 months after the operation under adjuvant chemotherapy using S-1.
