The role of positron emission tomography following radiosurgical treatment of malignant lung lesions.

Objective: To establish response patterns in PET following stereotactic body radiotherapy (SBRT) of malignant lung lesions.

Methods: Patients with malignant lung lesions treated with SBRT were retrospectively reviewed. All patients received 40-52 Gy in three to five equal fractions.

Frameless image-guided stereotactic body radiation therapy for lung tumors with 4-dimensional computed tomography or 4-dimensional positron emission tomography/ computed tomography.

Background/purpose: To augment the accuracy of stereotactic body radiation therapy (SBRT), a variety of image guidance systems are used for patient positioning and target localization. Clinical outcomes evaluating these systems, especially frameless image-guided systems, are still limited. This article aims to describe and evaluate our frameless image-guided SBRT technique for lung tumors.

Locoregional and distant failure following image-guided stereotactic body radiation for early-stage primary lung cancer.

Purpose: To report our institutional experience using image-guided stereotactic body radiation therapy (SBRT) for early stage lung cancer, including an analysis into factors associated with nodal and distant failures (NF, DF).

Methods: Forty-eight patients with early-stage primary lung cancer were treated with image-guided SBRT between 2007 and 2009. Median prescription dose was 48 Gy in 4 fractions.

Toxicity analysis of postoperative image-guided intensity-modulated radiotherapy for prostate cancer.

Purpose: To report on the acute and late gastrointestinal (GI) and genitourinary (GU) toxicity associated with a unique technique of image-guided radiotherapy (IGRT) in patients undergoing postprostatectomy irradiation.

Methods And Materials: Fifty patients were treated with intensity-modulated radiation therapy (IMRT) after radical prostatectomy. Daily image guidance was performed to localize the prostate bed using kilovoltage imaging or cone-beam computed tomography.
