AIM The aim of this study was to prove the diagnostic value of interim 18F-Fluorodeoxyglucose-positron-emission tomography combined with computed tomography (PET/CT) scan for predicting pathological complete response (pCR) compared to other factors in neoadjuvant chemotherapy. PATIENTS AND METHODS Twenty-seven patients with breast cancer were included in this retrospective study. They all und...
OBJECTIVE To investigate the validity of CT perfusion in assessing angiogenic activity of lung cancer. METHODS Fifty-six patients with lung cancer scheduled for elective surgical resection received 16-slice helical CT perfusion imaging. Time-density curve (TDC), blood flow (BF), blood volume (BV), mean transmit time (MTT) and permeability surface area product (PS) were calculated. 18F-deoxygl...
An observational finding found a large variation in the brain SUV in patients with multiple myeloma undergoing PET/CT. The first hypothesis considered a toxic effect of chemotherapeutic agents, but no correlation was found with hematological signs of toxicity. Low brain FDG uptake has been described with anesthesia, but this was not relevant in this case. An alternative is the presence of a lar...
AIM To determine the relationship between F-18 fluorodeoxyglucose (FDG) uptake of bone marrow (BM) on positron emission tomography/computed tomography (PET/CT) and clinical factors and to assess the prognostic value of FDG uptake of BM in gastric carcinoma. METHODS We retrospectively enrolled 309 gastric cancer patients who underwent staging FDG PET/CT and curative surgical resection. FDG upt...
BACKGROUND/AIM We aimed to define the optimal SUV(max) cut-off value in determination of mediastinal-hilar lymph node metastasis, by comparing positive PET/CT results with the results of endobronchial ultrasound guided transbronchial needle aspiration biopsy (EBUS-TBNA). MATERIALS AND METHODS Thirty-one patients with malignancy whose PET/CT imaging revealed a hypermetabolic mediastinal and/or...
Silkworm Thorn Stem Extract Targets RSK2 and Suppresses Solar UV-Induced Cyclooxygenase-2 Expression
Excessive exposure to solar UV (sUV) is associated with numerous human skin disorders, such as carcinogenesis, skin photoaging and skin inflammation. Silkworm Thorn (Cudraniatricuspidata, SW) is a plant belonging to the Moraceae family and widely present throughout Korea, China, and Japan. Most parts of the tree (including the fruit, leaf, stem, root, and bark) is consumable as a functional foo...
Background/Aim: Although numerous prognostic factors have been described for non-small cell lung cancer (NSCLC), there is still a requirement for better and non-invasive markers. FDG-PET is a non invasive diagnostic tool that is being used increasingly in the diagnosis of lung cancer. This study evaluates the prognostic values of PET/CT defined SUV measurements and other patient/tumor character...
We determined if specific tumor types of non-small cell lung cancer can be identified by variance in FDG-PET standard uptake value (SUV) in combination with characteristics on CT. Staging FDG-PET and CT scans of 81 patients (34 men and 47 women, average age 67+/-11 years) with 82 lung cancers were analyzed. Mean tumor SUV was calculated at the location of maximum FDG uptake. Tumor size, margins...
The maximum standardized uptake value (SUV(max)) varies among positron emission tomography-integrated computed tomography (PET/CT) centers in the staging of non-small cell lung cancer. We evaluated the ratio of the optimum SUV(max) cut-off for the lymph nodes to the median SUV(max) of the primary tumor (ratioSUV(max)) to determine SUV(max) variations between PET/CT scanners. The previously desc...
e102 Journal of Thoracic Oncology ® • Volume 10, Number 10, October 2015 importance of the T-stage and have reanalyzed our primary data. By analysis of variance and the Wilcoxon rank sum test, we show that the distribution of maximum standardized uptake value (SUV max ) within the three “T” groups (T1a/T1b/T2a) is significantly different (p < 0.0001). Cox proportional hazards model was then use...
