Predictive factors of late radiation fibrosis: a prospective study in non-small cell lung cancer.
To determine predictive factors of late radiation fibrosis (RF) after conformal radiotherapy (3D-RT) in non-small cell lung cancer (NSCLC). ⋯ This study confirms the importance of dosimetric parameters to limit the risk of RF. Contrary to acute radiation pneumonitis, RF was not correlated to cytokine variations during 3D-RT.

Prospective evaluation of radiotherapy with concurrent and adjuvant temozolomide in children with newly diagnosed diffuse intrinsic pontine glioma.
To present outcome data in a prospective study of radiotherapy (RT) with concurrent and adjuvant temozolomide (TMZ) in children with diffuse intrinsic pontine gliomas (DIPGs). ⋯ TMZ with RT has not yielded any improvement in the outcome of DIPG compared with RT alone. Further clinical trials should explore novel treatment modalities.

A phase I dose-escalation study (ISIDE-BT-1) of accelerated IMRT with temozolomide in patients with glioblastoma.
To determine the maximum tolerated dose (MTD) of fractionated intensity-modulated radiotherapy (IMRT) with temozolomide (TMZ) in patients with glioblastoma. ⋯ Accelerated IMRT to a dose of 65 Gy in 25 fractions is well tolerated with TMZ at a daily dose of 75 mg.

The association between biological subtype and isolated regional nodal failure after breast-conserving therapy.
To evaluate the risk of isolated regional nodal failure (RNF) among women with invasive breast cancer treated with breast-conserving surgery (BCS) and radiation therapy (RT) and to determine factors, including biological subtype, associated with RNF. ⋯ Isolated RNF is a rare occurrence after breast-conserving therapy. Patients with the HER-2 (not treated with trastuzumab) and basal subtypes appear to be at higher risk of developing RNF although this risk is not high enough to justify the addition of RNI. Low rates of RNF in patients with one to three positive nodes suggest that tangential RT without RNI is reasonable in most patients.

Portal hypertension in children with Wilms' tumor: a report from the National Wilms' Tumor Study Group.
This analysis was undertaken to determine the cumulative risk of and risk factors for portal hypertension (PHTN) in patients with Wilms' tumor (WT). ⋯ There was a strong association between higher doses of liver RT (>15 Gy) and the development of PHTN among WT patients.
