Multicenter StudySurvey of stereotactic body radiation therapy in Japan by the Japan 3-D Conformal External Beam Radiotherapy Group.
To recognize the current status of stereotactic body radiotherapy (SBRT) in Japan, using a nationwide survey conducted by the Japan 3-D Conformal External Beam Radiotherapy Group. ⋯ The current status of SBRT in Japan was surveyed.

Comparative StudyIntra-arterial infusion chemotherapy using cisplatin with radiotherapy for Stage III squamous cell carcinoma of the cervix.
To examine the effectiveness of concomitant intra-arterial infusion chemotherapy (IAIC) using cisplatin (CDDP) with radiotherapy for Stage III squamous cell carcinoma of the cervix. ⋯ A combination of IAIC and systemic chemotherapy should be considered to improve the prognosis of patients with Stage III squamous cell carcinoma of the cervix.

Comparative StudyProspective comparison of surgery alone and chemoradiotherapy with selective surgery in resectable squamous cell carcinoma of the esophagus.
Esophagectomy remains the mainstay treatment for esophageal cancer, although retrospective studies have suggested that chemoradiotherapy (CRT) is as effective as surgery. To determine whether CRT can substitute for surgery as the primary treatment modality, we performed a prospective direct comparison of outcomes after treatment in patients with resectable esophageal cancer who had received CRT and those who had undergone surgery. ⋯ Treatment outcomes among patients with resectable thoracic esophageal squamous cell carcinoma were comparable or superior after CRT (with salvage therapy if needed) to outcomes after surgery alone.

Comparative StudyCorrelation between pre- and postimplant dosimetry for iodine-125 seed implants for localized prostate cancer.
In order to evaluate implant quality for permanent prostate brachytherapy in patients with localized prostate cancer, American Brachytherapy Society and ESTRO guidelines recommend that postimplant dosimetry should be performed. To understand more about the relationship between pre- and postimplant dosimetry, a comparison was made of patients who received iodine-125 ((125)I) brachytherapy between March 1995 and the end of 2004, using a preplan technique. ⋯ In this study, we showed that there is a strong correlation between transrectal ultrasound-based preimplant and CT-based postimplant dosimetry. The excellent correlation between prostate D90 and V100 values demonstrates they are both equally valid quality indices. Vi parameters are an additional measure that can be used to assess the quality of the implant.

Combined proton and photon conformal radiotherapy for intracranial atypical and malignant meningioma.
To evaluate retrospectively the efficacy of conformal fractionated radiotherapy combining proton and photon beams after primary surgery for treatment of atypical and malignant meningiomas. ⋯ Postoperative combination of conformal radiotherapy with protons and photons for atypical and malignant meningiomas is a well-tolerated treatment producing long-term tumor stabilization.
