Early Multiple Primary Lung Cancer without Fluorodeoxyglucose Uptake on Positron Emission Tomography-Computed Tomography and Displaying Different EGFR Molecular Profiles
نویسندگان
چکیده
To the Editor: Multiple primary lung cancer (MPLC) refers to the synchronous or metachronous appearance of more than one primary lung cancer in a single patient. The diagnosis of MPLC is complicated and it is often difficult to differentiate MPLC from metastatic lung cancers based on radiologic and histopathologic criteria alone. Moreover, the therapeutic regimens and prognosis for early MPLC and metastatic lung cancers are quite different.

Early detection of intravascular large B-cell lymphoma by 18FDG-PET/CT with diffuse FDG uptake in the lung without respiratory symptoms or chest CT abnormalities
Intravascular large B-cell lymphoma (IVLBCL) is a rare and aggressive subtype of systemic extranodal non-Hodgkin diffuse large B-cell lymphoma (DLBCL). We report a rare case of IVLBCL who showed diffuse 18F-fluorodeoxyglucose (FDG) uptake in the lung in FDG-positron emission tomography/computed tomography (PET/CT) without respiratory symptoms or chest CT abnormalities. Serum biochemical studies...

Objective The mortality of patients with locally advanced triple-negative breast cancer (TNBC) is high, and pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) is associated with improved prognosis. This retrospective study was designed and powered to investigate the ability of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) to predict pat...

Objective(s): Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. Methods: Three hollow models were filled with 55.0 kBq/mL fluorine18- fluorodeoxyglucose (18F-FDG) to represent tumors. The models were fixed to a barrel filled w...
متن کاملThe effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
