Impact of various prognostic factors on survival in glioblastoma: tertiary care institutional experience.

Introduction: Glioblastoma is the most common malignant brain tumour in adults. Among all gliomas, it is the most aggressive type, with a high fatality rate, and according to the WHO classification, it is a grade IV tumour. As this tumour is well-known for its poor survival, an understanding of clinical and treatment-related prognostic factors can help in tailored treatment.

A Prospective Study Comparing Functional Imaging (F-FDG PET) Versus Anatomical Imaging (Contrast Enhanced CT) in Dosimetric Planning for Non-small Cell Lung Cancer.

Objectives: F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET-CT) is a well-used and established technique for lung cancer staging. Radiation therapy requires accurate target volume delineation, which is difficult in most cases due to coexisting atelectasis. The present study was performed to compare the F-FDG PET-CT with contrast enhanced computed tomography (CECT) in target volume delineation and investigate their impacts on radiotherapy planning.
