Idiopathic pulmonary fibrosis (IPF) is a destructive inflammatory disease with limited therapeutic options. Inflammation plays an integral role in the development of pulmonary fibrosis. Unresolved inflammatory responses can lead to substantial tissue injury, chronic inflammation, and fibrosis. The resolvins are a family of endogenous ω-3 fatty acid(More)
A 24-year-old woman was admitted to our department for further examination of hypercalcemia, a high level of intact parathyroid hormone (PTH) and a right parathyroid tumor. She complained of bone pain throughout her body and was unable to walk due to systemic cystic osteofibrosis, including a brown tumor of the left lower extremities. Neck ultrasonography(More)
Cysteinyl leukotrienes (cysLTs), which include leukotriene C4 (LTC4), are the predominant class of LTs synthesized by mast cells. CysLTs can induce many of the abnormalities seen in asthma. LTC4 is generated by the conjugation of LTA4 with reduced glutathione (GSH) by LTC4 synthase. During screening of the effects of prostanoids on high-affinity IgE(More)
The efficacy of gefitinib [an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor] in elderly patients with non-small cell lung cancer (NSCLC) and EGFR mutation has not been elucidated. Therefore, the objective of this study was to investigate the efficacy and feasibility of gefitinib in elderly chemotherapy-naive patients with NSCLC harboring(More)
BACKGROUND The aim of this study was to improve tumor control, the survival rate and organ preservation for locally advanced head and neck cancer by using induction chemotherapy followed by hyperfractionated radiotherapy and concurrent chemotherapy. MATERIALS AND METHODS Thirty-five patients with stage III-IVB head and neck cancer were treated with this(More)
Radiotherapy plays an important role in the management of cancer patients, and half of the patients with malignant tumors are treated with radiotherapy in the United States. In Japan, the necessity of radiation therapy has come to be widely acknowledged in cancer treatment, and more and more cancer patients are being treated with radiation. External beam(More)
PURPOSE Radiotherapy is considered to be associated with psychological distress. We assessed the mental status, anxiety, and the factors associated with these in cancer patients about to receive radiotherapy. MATERIALS AND METHODS Hospitalized patients about to receive radiotherapy participated. Psychological status was assessed by a psychiatrist, based(More)
PURPOSE The aims of this study were twofold: (1) to examine the effects of dual inhibition of 2 members of the HER family, the epidermoid growth factor receptor (EGFR) and HER2/neu, by gefitinib (ZD1839) and trastuzumab on radiosensitivity; and (2) to explore the molecular mechanism of radiosensitization especially focusing on the survival signal(More)
Previously, we conducted a nationwide survey of primary central nervous system lymphoma (PCNSL) treated between 1985 and 1994 in Japan. In the present study, we conducted further investigations of PCNSL patients treated between 1995 and 1999 to clarify possible changes with time in the clinical features, treatment, and outcome of this disease. Thirteen(More)
In patients with epidermal growth factor receptor (EGFR)-mutated, advanced, non-small cell lung cancer (NSCLC), common gefitinib-sensitive EGFR mutations that predict a greater response to therapy include the exon 19 deletion and L858R point mutation. The objective of this study was to evaluate whether body surface area (BSA), body weight (BW), and body(More)
