INTRODUCTION Hypofractionated stereotactic radiotherapy (HypoFXSRT) has recently been used for the treatment of small lung tumors. We retrospectively analyzed the treatment outcome of HypoFXSRT for stage I non-small cell lung cancer (NSCLC) treated in a Japanese multi-institutional study. METHODS This is a retrospective study to review 257 patients with(More)
PURPOSE To evaluate the daily setup accuracy and the reduction of respiratory tumor movement using a body frame in conformal therapy for solitary lung tumor. METHODS AND MATERIALS Eighteen patients with a solitary lung tumor underwent conformal therapy using a body frame. The body shell of the frame was shaped to the patient's body contour. The(More)
BACKGROUND Stereotactic irradiation (STI) has been actively performed using various methods to achieve better local control of Stage I nonsmall cell lung carcinoma (NSCLC) in Japan. The authors retrospectively evaluated results from a Japanese multiinstitutional study. METHODS Patients with Stage I NSCLC (n = 245; median age, 76 years; T1N0M0, n = 155;(More)
PURPOSE To review treatment outcomes for stereotactic body radiotherapy (SBRT) in medically operable patients with Stage I non-small-cell lung cancer (NSCLC), using a Japanese multi-institutional database. PATIENTS AND METHODS Between 1995 and 2004, a total of 87 patients with Stage I NSCLC (median age, 74 years; T1N0M0, n=65; T2N0M0, n=22) who were(More)
PURPOSE To assess errors resulting from manual transfer of contour information for three-dimensional (3-D) target reconstruction, and to determine variations in target volume delineation of brain tumours by different radiation oncologists. MATERIALS AND METHODS Images of 18 patients with intracranial astrocytomas were used for retrospective treatment(More)
PURPOSE Clinical results of intraoperative radiotherapy (IORT) and/or external beam radiotherapy (EBRT) for both resectable and unresectable pancreatic cancer were analyzed. METHODS AND MATERIALS Between 1980 and 1995, 332 patients with pancreatic cancer were treated with surgery and/or radiation therapy (RT). Of the 332 patients, 157 patients were(More)
PURPOSE To evaluate the computed tomographic (CT) appearance of tumors and lung injury in patients who have undergone stereotactic radiation therapy (SRT) for solitary lung tumors. MATERIALS AND METHODS Twenty-seven patients with primary lung cancer and four with metastatic lung cancer who underwent SRT for solitary lung tumors were enrolled for(More)
PURPOSE This study was performed to evaluate the clinical outcomes of three-dimensional (3D) conformal hypofractionated single high-dose radiotherapy for one or two lung tumors using a stereotactic body frame. MATERIALS AND METHODS Forty patients who were treated between July 1998 and November 2000 and were followed for >10 months were included in this(More)
BACKGROUND Although breast-conserving surgery followed by definitive irradiation is an established treatment for patients with early breast cancer, the role of breast-conserving therapy (BCT) for patients with bilateral breast cancer has not been well studied and the radiation therapy technique is still under investigation. We examined the feasibility of(More)
Systemic chemotherapy has been increasingly used in the primary treatment of intracranial germinoma. However, the recurrence rate seems to be very high after treatment with chemotherapy alone. We used radiation to treat 5 patients harboring intracranial germinoma that recurred following primary chemotherapy. They had received systemic chemotherapy (4 with(More)
