INTRODUCTION This study was performed retrospectively to evaluate the outcome of patients with stage III non-small cell lung cancer (NSCLC) after proton beam therapy (PBT) alone. METHODS The subjects were 57 patients with histologically confirmed NSCLC (stage IIIA/IIIB: 24/33) who received PBT without concurrent chemotherapy. The cohort included 32 cases(More)
INTRODUCTION This study was conducted to determine disease control rates and prognostic factors associated with recurrence of centrally and peripherally located stage I NSCLC treated using high-dose PBT. PATIENTS AND METHODS Seventy-four patients with 80 centrally or peripherally located stage I NSCLCs were treated with PBT. A protocol using 72.6 Gy (RBE)(More)
The purpose of the present study was to develop a new method of chemoembolization to improve the therapeutic effectiveness and safety profile of cancer treatment. A chemoembolization approach was designed for human solid tumors using resorbable calcium-phosphate ceramic microspheres loaded with an agent anti-angiogenic to tumor vasculature in vivo. The(More)
BACKGROUND/AIM The aim of the present study was to evaluate the outcomes of proton beam therapy (PBT) concurrently combined with chemotherapy consisting of cisplatin and 5-fluorouracil for esophageal cancer. PATIENTS AND METHODS Forty consecutive patients (stage I in 16 patients, II in 9 and III in 15) treated between 2008 and 2012 were evaluated. A total(More)
BACKGROUND Proton-beam therapy (PBT) provides therapeutic advantages over conformal x-ray therapy in sparing organs at risk when treating esophageal cancer because of the fundamental physical dose distribution of the proton-beam. However, cases with extended esophageal lesions are difficult to treat with conventional PBT with a single isocentric field, as(More)
The purpose of this study was to compare the parameters of the dose-volume histogram (DVH) between proton beam therapy (PBT) and X-ray conformal radiotherapy (XCRT) for locally advanced non-small-cell lung cancer (NSCLC), according to the tumor conditions. A total of 35 patients having NSCLC treated with PBT were enrolled in this analysis. The numbers of(More)
Surgical resection is the first choice for treatment of a thymic carcinoid tumor and radiotherapy is often performed as adjuvant therapy. Here, we report a case of an unresectable and chemoresistant thymic carcinoid tumor that was treated successfully using standalone proton beam therapy (PBT). The patient was a 66-year-old woman in whom surgical resection(More)
