Abstract

Though challenging, maximal safe resection of insular gliomas enhances overall and progression-free survival and deters malignant transformation. Previously published reports have shown that surgery can be performed with low morbidity. The authors previously described a Berger-Sanai zone classification system for insular gliomas. Using a subsequent dataset, they undertook this study to validate this zone classification system for predictability of extent of resection (EOR) in patients with insular gliomas. The study population included adults who had undergone resection of WHO Grade II, III, or IV insular gliomas. In accordance with our prior published report, tumor location was classified according to the Berger-Sanai quadrant-style classification system into Zones I through IV. Interobserver variability was analyzed using a cohort of newly diagnosed insular gliomas and independent classification scores given by 3 neurosurgeons at various career stages. Glioma volumes were analyzed using FLAIR and T1-weighted contrast-enhanced MR images. One hundred twenty-nine procedures involving 114 consecutive patients were identified. The study population from the authors' previously published experience included 115 procedures involving ...Continue Reading

Cancer Incidence & Mortality

Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.

Cancer Imaging

Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.
