Practice patterns and outcomes with the use of regorafenib in metastatic colorectal cancer: Results from the Regorafenib in Metastatic colorectal cancer - An Indian exploratory analysis study.

Background: Regorafenib is considered a standard of care as third-line therapy in metastatic colorectal cancers (mCRCs).

Materials And Methods: The study was based on a computerized clinical data form sent to oncologists across the country for entry of anonymized patient data. The data entry form was conceived and generated by the coordinating center's (Tata Memorial Hospital) gastrointestinal medical oncologists and disseminated through personal contacts at academic conferences as well as through E-mail to various oncologists across India.

FDG-PET and PET/CT in the clinical management of gastrointestinal stromal tumor.

The management of gastrointestinal stromal tumors (GISTs) has been revolutionized in recent years by two major developments: the introduction of imatinib mesylate as a targeted therapeutic agent and the dramatic change in the tumor metabolic activity following successful therapy making in fluorodeoxyglucose (FDG)-PET as the modality of choice for monitoring therapeutic response. In the present communication, we have explored the current role of PET/computed tomography (CT) imaging in GIST on the basis of a brief overview of the published studies and our experience on the subject gained in a large tertiary care setting. There is now convincing evidence that serial PET study is more sensitive and reliable for determining treatment response to imatinib mesylate in patients of GIST, when compared with only conventional CT monitoring.
