OBJECTIVES: 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 fluorine-18 fluorodeoxyglucose ((18)F-FDG) to represent tumors. The models were fixed to a barrel filled with 5.9 kBq/mL (18)F-FDG to characterize normal lung tissues as a phantom...

The prognostic quality of increased osteopontin (OPN) plasma levels has been demonstrated for the chemotherapy and surgery of lung cancer. There is also evidence in the literature that tumor volume impacts prognosis in definitive radiotherapy (RT) of (lung) cancer. We previously demonstrated that elevated plasma levels of OPN before, and increasing OPN plasma levels after RT significantly correlate with survival and outcome after curative-intent RT of non-small-cell lung cancer (NSCLC). Tumor volume was also associated with prognosis...

The objective of our study was to examine the anti-tumor effect of paclitaxel (PTX)-loaded polymeric nanoparticles (PTX-NPs) combined with circadian chronomodulated chemotherapy. Our intention was to screen out the best time of the day for the drug to be administered. PTX-NPs with a diameter of approximately 168nm were prepared through a thin film dispersion technique. The PTX in PTX-NPs showed an initial fast release subsequently a slower and sustained release. The cytotoxicity of chronomodulated administration of PTX-NPs in vitro confirmed that its cytotoxic effect was lower than that of PTX injection, and showed a time-dependent effect...

The differential diagnosis of a pulmonary mass in an immunosuppressed host with a history of cancer is broad and includes malignant, infectious and inflammatory etiologies. Mycobacterium avium complex (MAC) is a rare cause of opportunistic infection in susceptible individuals that can present as either localized or disseminated disease. On radiologic studies, the pulmonary disease can manifest as heterogeneous linear or nodular densities, a mass-like lesion, or thin-walled cavitary lesions. We present the case of pulmonary MAC in a patient with a history of lung cancer requiring lobectomy, and splenic lymphoma being treated with chemotherapy, presenting with extreme fatigue and a fludeoxyglucose (FDG)-avid mass on positron emission tomography-computed tomography (PET-CT)...

Positron emission tomography/integrated computed tomography (PET/CT) provides the most accurate imaging modality for preoperative lung cancer staging. However, the diagnostic accuracy of maximum standardized uptake value (SUVmax) for mediastinal (N2) lymph nodes (LN) is unclear. We compared SUVmax, the ratio of LN to primary tumor SUVmax (SUVn/t), and SUVn/t multiplied by maximal tumor diameter (SUVindex) in terms of their abilities to predict mediastinal LN malignancy.We retrospectively analyzed 170 mediastinal LN stations from 73 consecutive patients who underwent systemic LN resection and PET/CT within 27 days...

Gastric metastases from lung adenocarcinoma are rare and usually asymptomatic. A 61-year-old woman was referred to our department because of a right lower pulmonary mass found on a chest X-ray film in August 2012. Right lower lobectomy was performed for pulmonary adenocarcinoma. Four months later, she developed epigastric discomfort. A fluoro-deoxy-glucose positron emission tomography/computed tomography (FDG-PET/CT) scan showed a malignancy at the cardias of the stomach. A biopsy diagnosed poorly differentiated carcinoma and a gastric carcinoma was suspected...

A 28-year-old woman with medullary thyroid cancer treated with total thyroidectomy and bilateral central and right lateral neck nodal resection postoperatively had increasing calcitonin and carcinoembryonic antigen values. A Ga-DOTANOC PET/CT study performed showed tracer-avid disease in the neck, mediastinal, and hilar lymph nodes. However, there were 3 tracer-avid foci in the lungs bilaterally, suggestive of lung metastases but with no corresponding abnormalities on low-dose CT. A negative contrast-enhanced CT of the lungs along with clinical and radiological follow-up confirmed that the lung activity was artifactual, demonstrating the possibility of Ga-DOTANOC-avid iatrogenic pulmonary microembolism...

BACKGROUND: Hypoxic tumours exhibit increased resistance to radiation, chemical, and immune therapies. (18)F-fluoromisonidazole (FMISO) positron emission tomography (PET) is a non-invasive, quantitative imaging technique used to evaluate the presence and spatial distribution of tumour hypoxia. To facilitate the use of FMISO PET for identification of individuals likely to benefit from hypoxia-targeted treatments, we investigated the reproducibility of FMISO PET spatiotemporal intratumour distribution in patients with non-small cell lung cancer (NSCLC)...

INTRODUCTION: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are a treatment option in the second- or third-line palliative setting in EGFR wild-type (wt) non-small cell lung cancer (NSCLC) patients. However, response rates are low, and only approximately 25% will achieve disease control. Early prediction of treatment resistance could accelerate discontinuation of ineffective treatment and reduce unnecessary toxicity. In this study, we evaluated early changes on 18F-fluoro-D-glucose (F-18-FDG) positron emission tomography/computed tomography (PET/CT) and in total plasma cell-free DNA (cfDNA) as markers of erlotinib response in EGFR-wt patients...

Stage I breast carcinoma is classified when an invasive breast carcinoma is ≤2 cm in diameter (T1), with no regional (axillary) lymph node metastases (N0) and no distant metastases (M0). The most common sites for metastases from breast cancer are the skeleton, lung, liver, and brain. In general, women and health care professionals prefer intensive screening and surveillance after a diagnosis of breast cancer. Screening protocols include conventional imaging such as chest radiography, bone scan, ultrasound of the liver, and MRI of brain...

INTRODUCTION: The Centers for Medicare and Medicaid Services (CMS) coverage includes three post-therapy FDG-PET/CT scans per patient and per tumor type. Any additional follow-up FDG-PET/CT will be reimbursed at the discretion of a local Medicare administrator, if deemed medically necessary. This study aims to investigate common clinical indications for performing a fourth or additional follow-up FDG-PET/CT scans which could impact management of patients. METHODS: This was a retrospective institutional review of 433 oncology patients (203 male, mean age 55 years), including a total of 1,659 fourth or subsequent follow-up PET/CT scans after completion of primary treatment...

INTRODUCTION: Cone-beam computed tomography (CBCT) is a valuable image-guidance tool in radiation therapy (RT). This study was initiated to assess the accuracy of CBCT for quantifying non-small cell lung cancer (NSCLC) tumour volumes compared to the anatomical 'gold standard', CT. Tumour regression or progression on CBCT was also analysed. METHODS: Patients with Stage I-III NSCLC, prescribed 60 Gy in 30 fractions RT with concurrent platinum-based chemotherapy, routine CBCT and enrolled in a prospective study of serial PET/CT (baseline, weeks two and four) were eligible...

PURPOSE: In patients with metastatic differentiated thyroid carcinoma (DTC), fluorodeoxyglucose (FDG) uptake as well as age, tumor size and radioactive iodine (RAI) uptake are prognostic factors for survival. High FDG uptake is a poor prognostic factor and lesions with high FDG uptake are often considered aggressive, but the predictive value of FDG uptake for morphological progression is unknown. The principal aim of this retrospective single center study was to determine whether the intensity of FDG uptake was correlated on a per lesion analysis with tumor growth rate (TGR) expressed as the percentage of increase in tumor size during 1 year (1-year TGR)...

Identification of evidenced-based Quality of Care (QoC) indicators for lung cancer care is essential to quality improvement. The aim of this review was to identify evidence-based quality indicators for the pre- and postoperative care of stage I-III Non Small Cell Lung Cancer (NSCLC) provided by the lung physician. To obtain these indicators, a search in PubMed, Embase and the Cochrane library database was performed. English literature published between 1980 and 2012 was included and search terms regarding 'lung neoplasms', 'quality of care', 'pathology', 'diagnostic methods', 'preoperative and postoperative treatment' were used...

Comprehensive genomic profiling for non-small cell lung cancer (NSCLC) is likely to identify more patients with rare genetic alterations including uncommon epidermal growth factor receptor gene (EGFR) mutations. It remains unclear how such patients should be treated, however. We here report a case of NSCLC positive for two uncommon mutations of EGFR and a KRAS mutation, including its treatment with the second-generation EGFR tyrosine kinase inhibitor (TKI) afatinib. Tumor specimen obtained by a NSCLC patient with no smoking history was analyzed by next-generation sequencing...
