The aim of this retrospective study is to evaluate the clinical impact and efficacy of fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) on management decisions for patients suffering from clinically operable non-small-cell lung cancer (NSCLC). A retrospective review of 186 potentially operable NSCLC patients who underwent whole-body PET/CT examination in 2012 was performed. The patients were further analyzed via the electronic patient record (ePR) system for relevant findings...

Thyroid gland is an uncommon site of metastasis, and metastasis to the gland secondary to nasopharyngeal carcinoma is seldom seen. We were only able to identify eight reported cases in the literature. A 61-year-old man, diagnosed case of nasopharyngeal cancer-second primary ( first primary-oropharynx), was found to have a thyroid nodule on routine follow-up positron emission tomography-computed tomography (PET-CT) scan. There was no evidence of metastases at any other sites. The thyroid nodule was confirmed as metastatic carcinoma by fine needle aspiration cytology...

Fluorine-18 labelled fluoroazomycinarabinoside ((18)F-FAZA) is a positron emission tomography (PET) biomarker for non-invasive identification of regional tumor hypoxia. Aim of the present Phase I study was to firstly evaluate in non-small cell lung cancer patients the human biodistribution and dosimetry of (18)F-FAZA. Methods: Five patients awaiting surgical resection after histologically proven or radiologically suspected non-small cell lung cancer were prospectively enrolled for the study. The patients underwent a PET/computed tomography (CT) study after the injection of 371±32 MBq of (18)F-FAZA...

A 63-year-old man with a history of prostate cancer, treated with resection, radiation, and androgen-depriving therapy over 4 years, was referred to our department with suspicion of recurrence based on increased blood PSA levels (1.60 ng/mL). Ga PSMA PET/CT identified a solitary, PSMA-positive pulmonary nodule in the right lung. After resection, histologic analysis confirmed prostatic origin, and the blood PSA level decreased to 0.13 ng/mL. Solitary pulmonary metastasis from prostate cancer is rare. The benefits of local treatment of a single metastasis even in advanced disease are disputed among oncologists...

PURPOSE: 18F-FDG PET/CT is widely used to evaluate indeterminate pulmonary nodules (IPNs). False positive results occur, especially from active granulomatous nodules. A PET-based imaging agent with superior specificity to 18F-FDG for IPNs, is badly needed, especially in areas of endemic granulomatous nodules. Somatostatin receptors (SSTR) are expressed in many malignant cells including small cell and non-small cell lung cancers (NSCLCs). 68Ga-DOTATATE, a positron emitter labeled somatostatin analog, combined with PET/CT imaging, may improve the diagnosis of IPNs over 18F-FDG by reducing false positives...

Prostate-specific membrane antigen (PSMA) is highly expressed in prostate cancer, and the expression increases with tumor aggressiveness, metastatic disease, and recurrence. Despite its name, PSMA is also expressed in neovasculature of other tumors including lung cancer. Here, we demonstrate a case of increased PSMA expression on Ga-PSMA PET/CT in benign lung opacities and bronchiectasis in a prostate cancer patient. Thus, increased PSMA activity in the lungs may be due to both benign and malignant diseases and warrants further evaluation...

In the era of extensive imaging and increasing indications for performing PET-CT scans, the recognition of synchronous tumors may be greater than before. However, the majority of these tumors are seen to occur in the same organ system, likely because of sharing similar pathogenic mechanisms. Synchronous lung cancers of similar or differing histologies have been reported. Primary pulmonary lymphoma, which is a rare form of non-Hodgkin's lymphoma, has also been seen with a synchronous primary lung cancer. However, we report a case of a 56-year-old male diagnosed with primary pulmonary lymphoma and on PET-CT imaging, found to have a cecal lesion, the biopsy of which showed adenocarcinoma...

Multidisciplinary therapy is necessary to prevent recurrence of advanced rectal cancer and advanced cancer with metastases. Here we report a case of long-term survival of a patient with advanced rectal cancer with multiple liver metastases. An 80's woman had previously undergone both Hartmann's operation and a partial hepatectomy for advanced rectal cancer with multiple liver metastases. A year after chemotherapy, a CT scan revealed multiple liver metastases. Thus, we performed partial liver resection. After another round of chemotherapy, a CT scan revealed lung metastases and local recurrence of the rectal cancer; therefore, we performed partial lung resection and a Miles operation...

We report a case of minimal thyroid carcinoma diagnosed by a solitary pulmonary metastasis. A 70's man visited a medical practitioner because of chest discomfort, and there was an abnormality on the chest X-ray. Chest computed tomography(CT) showed a nodule in the right middle lobe of the lung. Positron emission tomography with 18-fluorodeoxyglucose(FDG)-PET revealed increased FDG uptake in that tumor, but did not reveal any other lesion. The tumor was clinically suspected to be a carcinoid tumor, primary lung cancer, metastatic lung cancer, or a benign tumor...
