REVIEW
Sarah J Counts, Anthony W Kim
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...

BACKGROUND: This work aims to assess the feasibility of selectively sparing the hippocampus during prophylactic cranial irradiation (PCI) for small cell lung cancer (SCLC). METHODS: SCLC patients with brain metastases (BMs) diagnosed with MRI were enrolled. Lesions localized to the neural stem cell (NSC) compartments [subventricular zone (SVZ) or hippocampus] were analyzed. Patients were categorized by the total number of intracranial metastases, the therapy processes and the symptoms...

Leptomeningeal carcinomatosis is a rare but serious complication of solid tumors such as melanoma, breast and lung cancer, as well as gastrointestinal carcinomas. Its clinical manifestation is highly variable, presenting as radicular pain with or without neurological deficits, as well as with headaches and hallucinatory irritation symptoms. Leptomeningeal carcinomatosis is often misdiagnosed, which delays treatment. Here we report a rare case of a patient with BRAF-mutated microsatellite stable colon carcinoma with lymphatic and skeletal metastases, who developed neurological symptoms one month after the initial diagnosis of malignancy...

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...

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...

Previous studies have been conducted on the prognostic factors for overall survival in patients with brain metastases (BMs) following whole brain radiotherapy (WBRT). However, there have been a small number of studies regarding the prognostic factors for the response of tumor to WBRT. The aim of the present study was to identify the predictive factors for the response to WBRT from the point of view of reduction of tumor using magnetic resonance imaging. A retrospective analysis of 62 patients with BMs from primary lung cancer treated with WBRT was undertaken...

Surrogate-based tumor motion estimation and tracing methods are commonly used in radiotherapy despite the lack of continuous real time 3D tumor and surrogate data. In this study, we propose a method to simultaneously track the tumor and external surrogates with dynamic MRI, which allows us to evaluate their reproducible correlation. Four MRI-compatible fiducials are placed on the patient's chest and upper abdomen, and multi-slice 2D cine MRIs are acquired to capture the lung and whole tumor, followed by two-slice 2D cine MRIs to simultaneously track the tumor and fiducials, all in sagittal orientation...

Small molecules, mainly tyrosine kinase inhibitors, are currently used in various malignancies. Lapatinib, a dual inhibitor of EGFR/HER2 tyrosine kinases, has demonstrated effectiveness in brain metastases from HER2-overexpressing breast cancer. It also appears to sensitize EGFR-expressing cell lines to radiation. To evaluate the efficacy of lapatinib in combination with whole brain radiotherapy (WBRT) in patients with brain metastases from non-small cell lung cancer (NSCLC) and breast cancer, as assessed by volumetric analysis by MRI...

BACKGROUND Sarcomatoid carcinoma is a rare, aggressive, malignant cancer composed of sarcoma and sarcoma-like components, and can occur in different organs such as the thyroid gland, bone, skin, breast, pancreas, liver, urinary tract, and lung. Pulmonary sarcomatoid carcinoma accounts for only a small percentage of lung cancers and has histological variants that include pleomorphic carcinoma, giant cell carcinoma, spindle cell carcinoma, carcinosarcoma, and pulmonary blastoma. CASE REPORT Here, we present a case of sarcomatoid carcinoma in a 63-year-old HIV-positive Hispanic male who presented with back pain, dry cough, and weight loss...

OBJECTIVE: The use of PET CT for staging in cancer patients and the widespread use of MRI led to an increased incidence of incidental sellar mass detection. The imaging findings can be suggestive of a benign pituitary tumor but metastasis can never be completely ruled out with non-invasive work-up. Appropriate diagnosis of these sellar masses is critical as the treatment paradigm might change in the presence of a pituitary metastasis. Moreover, definitive tissue diagnosis might prevent unnecessary radiotherapy to the skull base or even the need for systemic treatment when benign pituitary disease is confirmed...

Solitary choroidal metastasis as an initial presentation of lung cancer is rare. A 67-year-old woman who initially presented with a 3-month history of blurred vision in the right eye was suggestive of choroidal melanoma on MRI. Preoperatively, a pulmonary mass was found on x-ray. She was referred for an FDG PET/CT imaging, which revealed a choroidal lesion with minimal FDG uptake in right eye and increased FDG activity in the known lung mass. A pathological diagnosis of metastatic lung adenocarcinoma was made after enucleation of the right eyeball...

Personalized and precision medicine is gaining recognition due to the limitations by standard diagnosis and treatment; many areas of medicine, from cancer to psychiatry, are moving towards tailored and individualized treatment for patients based on their clinical characteristics and genetic signatures as well as novel imaging techniques. Advances in whole genome sequencing have led to identification of genes involved in a variety of diseases. Moreover, biomarkers indicating severity of disease or susceptibility to treatment are increasingly being characterized...

The conventional chemotherapeutics could not be traced in vivo and provide timely feedback on the clinical effectiveness of drugs. In this study, poly(L-γ-glutamyl-glutamine)-paclitaxel (PGG-PTX), as a model polymer, was chemically conjugated with Gd-DTPA (Gd-diethylenetriaminepentaacetic acid), a T1-contrast agent of MRI, to prepare a Gd-DTPA-conjugated PGG-PTX (PGG-PTX-DTPA-Gd) delivery system used for tumor theranostics. PGG-PTX-DTPA-Gd can be self-assembled to NPs in water with a z-average hydrodynamic diameter about 35...

This report presents the case of a 60-year-old woman who was diagnosed with stage IV lung adenocarcinoma with asymptomatic brain metastases and commenced chemotherapy with cisplatin/pemetrexed (CDDP/Pem). She experienced tonic-clonic convulsions on day 9 of the first cycle, which were accompanied by increased blood pressure (173/69 mm Hg) and headache. Therefore, brain MRI was performed to check for stroke or progression of brain metastatic foci. T2-weighted, FLAIR, and ADC map images showed high-intensity areas in the subcortical region of the bilateral parieto-occipital lobes, leading to a diagnosis of posterior reversible encephalopathy syndrome (PRES)...

INTRODUCTION: Multifocal lung cancer (MFLC) is an increasingly common clinical scenario but there is lack of high-level evidence for its optimal treatment. Thus, we surveyed members of the interdisciplinary International Association for the Study of Lung Cancer (IASLC) on their therapeutic approaches and analyzed the resultant practice patterns. METHODS: We described the clinical scenario of an otherwise healthy 60 years old man with bilateral pulmonary nodules and asked the 6373 IASLC members whether they would recommend surgery, and if so, the extent of surgery...
