BACKGROUND: The benefit of invasive mediastinal nodal staging (IMNS) in addition to positron emission tomography-computed tomography (PET/CT) is undefined for early stage non-small cell lung cancer (NSCLC). This multi-institutional investigation aimed to evaluate outcomes and patterns of failure in patients staged with PET/CT with or without additional IMNS. METHODS: Two academic centers assessed all consecutive patients staged with PET/CT for early-stage, primary lung NSCLC (cT1-2aN0M0) treated with SBRT...

A 64-year-old woman underwent partial colectomy with partial resection ofthe retroperitoneum and D3 lymphadenectomy for descending colon cancer(tub2, pSS, ly0, v0, pN1, sH0, sP0, sM0, fStage III b). Three years and 6 months later, she underwent resection ofsegment 4 ofthe liver because ofliver metastasis. One year and 2 months later, her serum carcinoembryonic antigen level increased, and computed tomography showed an inferior mediastinal mass of 18mm in diameter. High FDG uptake by this tumor was seen on positron emission tomography-CT...

A 59-year-old man consulted our hospital because of an abnormal shadow on a chest computed tomography, located in the right lower lobe. Fluorodeoxyglucose-positron emission tomography showed abnormal uptake in the tumor suggesting lung cancer and right lower lobectomy was performed. Pathological the tumor was diagnosed as lung cancer comprising tall columnar cells. Immunohistochemical staining was positive for TTF-1, CK-7 and CK-20. Postoperative screening of the abdomen revealed no suspicious primary lesion in the colon and the tumor was diagnosed as a pulmonary enteric adenocarcinoma...

BACKGROUND: Never-smokers with lung cancer often present late as there are no established aetiological risk factors. The aim of the study is to define the frequency over time and characterise clinical features of never-smokers presenting sufficiently early to determine if it is possible to identify patients at risk. METHODS: We retrospectively analysed data from a prospectively collected database of patients who underwent surgery. The frequency was defined as number of never-smokers versus current and ex-smokers by year...

We assessed the clinical value of 2-fluoro-2-deoxyglucose (18F-FDG) PET/CT imaging for predicting occult nodal metastasis in non-small cell lung cancer (NSCLC) patients. This retrospective study included 54 patients with T1-2N0M0 NSCLC who had undergone 18F-FDG PET/CT before surgery. Occult nodal metastasis was detected in 25.9% (14/54) of the patients. Immunohistochemical analysis revealed that increased glucose transporter 1 expression was associated with occult nodal metastasis, but hexokinase 2 expression was not...

BACKGROUND: Minimally invasive surgery, stereotactic radiotherapy, and radiofrequency ablation are commonly proposed in the case of pulmonary colorectal-metastasis as alternatives to conventional open surgery. Preoperative imaging assessment by computed tomography (CT) scan and fluorodeoxyglucose positron emission tomography (FDG-PET) are critical to guide oncologic radical treatment. Our aim was to investigate the accuracy of CT and FDG-PET for the evaluation of the number of pulmonary colorectal metastases and thoracic lymph nodal involvement (LNI)...

BACKGROUND: Measures of tumour heterogeneity derived from 18-fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scans are increasingly reported as potential biomarkers of non-small cell lung cancer (NSCLC) for classification and prognostication. Several segmentation algorithms have been used to delineate tumours, but their effects on the reproducibility and predictive and prognostic capability of derived parameters have not been evaluated. The purpose of our study was to retrospectively compare various segmentation algorithms in terms of inter-observer reproducibility and prognostic capability of texture parameters derived from non-small cell lung cancer (NSCLC) (18)F-FDG PET/CT images...

Modalities to detect and characterize lung cancer are generally divided into those that are invasive [endobronchial ultrasound (EBUS), esophageal ultrasound (EUS), and electromagnetic navigational bronchoscopy (ENMB)] versus noninvasive [chest radiography (CXR), computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI)]. This chapter describes these modalities, the literature supporting their use, and delineates what tests to use to best evaluate the patient with lung cancer...

Chemoradiotherapy, the standard of care for locally advanced non-small-cell lung cancer (NSCLC), often fails to eradicate all known disease. Despite advances in chemotherapeutic regimens, locally advanced NSCLC remains a difficult disease to treat, and locoregional failure remains common. Improved radiographic detection can identify patients at significant risk of locoregional failure after definitive treatment, and newer methods of escalating locoregional treatment may allow for improvements in locoregional control with acceptable toxicity...

Patients with locally advanced lung cancer and very limited pulmonary function (forced expiratory volume in 1 second [FEV1] ≤ 1 L) have dismal prognosis and undergo palliative treatment or best supportive care. We describe two cases of locally advanced node-positive non-small cell lung cancer (NSCLC) patients with very limited lung function treated with induction chemotherapy and moderate hypofractionated image-guided radiotherapy (Hypo-IGRT). Hypo-IGRT was delivered to a total dose of 45 Gy to the primary tumor and involved lymph nodes...

PURPOSE: The brain is the most common site of distant metastasis from lung cancer. Thus MRI of the brain at initial staging is routinely performed, but if this exam is negative a follow-up exam is often not performed. This study evaluates the incidence of asymptomatic brain metastases in non-small cell lung cancer patients detected on follow-uP(18)F- FDG PET/CT scans. MATERIALS AND METHODS: In this IRB approved retrospective review, all vertex to thigh (18)F- FDG PET/CT scans in patients with all subtypes of lung cancer from August 2014 to August 2016 were reviewed...

Fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) and four-dimensional CT (4DCT) are used in several methods for defining the biological target volume (BTV) in primary non-small cell lung cancer (NSCLC). Disagreements between the assessments using these methodologies make the use of BTV for radiotherapy planning controversial. In this study, we compared existing methods with our proposed internal biological target volume (IBTV) metric, derived by combining internal target volume (ITV) and BTV metrics...

BACKGROUND: Pituitary metastasis of lung cancer is rare; however, it often causes diabetes insipidus. Although the majority of such patients are treated with radiation therapy, it remains unclear whether diabetes insipidus can be controlled by radiation therapy. CASE: A 72-year-old man was admitted to our hospital for hemosputum, headache, and polyuria. A chest CT scan showed a 3.0 cm mass in the left upper lobe of his lung. Bronchofiberscopy results confirmed the pathological diagnosis of lung adenocarcinoma...
