Smoking History and Prior Surgical Resection Predict Sensitivity to Gefitinib in Advanced Non-Small-Cell Lung Cancer
Duplication cyst of the small intestine found by double-balloon endoscopy: A case report
A 35-year-old man was admitted due to bloody stool and anemia. The bleeding source could not be detected by esophagogastroduodenoscopy or colonoscopy. Double balloon endoscopy (DBE) revealed a diverticulum-like hole in which coagula stuck in the ileum at 1 meter on the oral side from the ileocecal valve. The adjacent mucosa just to the oral side of the hole was elevated like a submucosal tumor. The lesion was considered the source of bleeding and removed surgically. It was determined to be a cyst with an ileal structure on the mesenteric aspect accompanying gastric mucosa. The diagnosis was a duplication cyst of the ileum, which is a rare entity that can cause gastrointestinal bleeding. In the present case, DBE was used to find the hemorrhagic duplication cyst in the ileum

C609T Polymorphism of NADPH Quinone Oxidoreductase 1 Correlates Clinical Hematological Toxicities in Lung Cancer Patients Treated with Amrubicin
Background Amrubicin hydrochloride (AMR) is a key agent for lung cancer. NADPH quinone oxidoreductase 1 (NQO1) metabolizes the quinone structures contained in both amrubicin (AMR) and amrubicinol (AMR-OH). We hypothesized that NQO 1 C609T polymorphism may affect AMR-related pharmacokinetics and clinical outcomes. Methods Patients received AMR doses of 30 or 40 mg/m 2 /day on days 1–3. Plasma sampling was performed 24 hours after the first and third AMR injections. Concentrations of AMR and AMR-OH were determined by HPLC and the NQO 1 C609T polymorphism was assayed by RT-PCR. Results A total of 35 patients were enrolled. At a dose of 40 mg/m 2 , the T/T genotype exhibited a tendency toward a relationship with decrease concentrations of AMR-OH on days 2 and 4. The genotype also showed a significant decrease of hematological toxicities ( P < 0.05). Conclusions NQO 1 C609T polymorphism had a tendency of correlation with the plasma concentrations of AMR-OH, and thereby had significant correlations with hematologic toxicities
