Mimics of lung cancer.

[Mimics of lung cancer]. Radiologe. 2018 Dec 14;: Authors: Eisenhuber E, Schaefer-Prokop C, Mostbeck G Abstract Lung cancer is a histologically, immunologically and therefore morphologically and functionally very heterogeneous group of neoplasms with the highest cancer mortality worldwide. Therefore, the range of diseases mimicking lung cancer is also very broad and includes congenital, infectious and inflammatory changes as well as other benign space-occupying lesions and other primary and secondary pulmonary neoplasms. The difficulty in radiology lies in the ability to diagnose lung cancer with a high degree of certainty. This must take the limits of the specific diagnosis, knowledge of the classical pitfalls and rare entities that can imitate lung cancer into consideration. Narrowing the differential diagnosis requires close interdisciplinary cooperation and consideration of the patient's clinical and medical history. An accurate analysis of the computed tomography (CT) pattern and distribution of the lesions as well as consideration of additional changes and involvement of other organ systems can be the key to the diagnosis. The use of fluorodeoxyglucose positron-emission tomography CT (FDG-PET-CT) is helpful only in a few mimics of lung cancer. The article describes clinical and radiological findings of mimics of lung cancer also pointing out the limitations of CT and PET-CT for the diagnosis. PMID: 30552483 [PubMed - as supplied by p...

ConclusionsOccult nodal disease was frequently identified in peripheral N1 stations (11-13) in patients with small (≤2 cm) clinical N0 NSCLC. Hilar lymphadenectomy is essential for accurate staging in the management of patients with small clinical N0 NSCLC.

We present the case of an asymptomatic woman, a chronic heavy smoker, who presented with an incidental lung mass and mediastinal lymphadenopathy. Bronchoscopy with transbronchial biopsy and endobronchial ultrasound-guided transbronchial needle aspiration did not show malignancy. A positron emission tomography/computed tomography scan showed increased uptake with a standardized uptake value of 26.4 in the mediastinal lymph node and an additional hypermetabolic right supraclavicular lymph node. Surgical biopsy of the supraclavicular node revealed non-necrotizing granuloma. Discussion of the clinical dilemma is provided.

Abstract PURPOSE: To provide evidence-based recommendations to practicing clinicians on radiographic imaging and biomarker surveillance strategies after definitive curative-intent therapy in patients with stage I-III non-small-cell lung cancer (NSCLC) and SCLC. METHODS: ASCO convened an Expert Panel of medical oncology, thoracic surgery, radiation oncology, pulmonary, radiology, primary care, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000...

As awareness of the habits and risks associated with lung cancer has increased, so has the interest in promoting and improving upon lung cancer screening procedures. Recent research demonstrates the benefits of lung cancer screening; the National Lung Screening Trial (NLST) found as its primary result that preventative screening significantly decreases the death rate for patients battling lung cancer. However, it was also noted that the false positive rate was very high (>94%).In this work, we investigated the ability of various machine learning classifiers to accurately predict lung cancer nodule status while also cons...

Researchers are using artificial intelligence to measure a common marker of heart disease via lung cancer screenings. The research was presented at the annual meeting of the Radiological Society of North America (RSNA). Low-dose chest CT is approved for lung cancer screening in high-risk people, such as long-time smokers. While these CT scans are intended to diagnose lung cancer, coronary artery calcium, a measure of plaque in the arteries, is also visible on CT. The coronary artery calcium score derived from CT is a well-established measure that helps doctors decide who should get cholesterol-lowering preventive medicatio...

ConclusionsIn an experienced MTB, the agreement between imaging specialists and the rest of the MTB with regard to the interpretation of images is high in a setting of posttreatment lung cancer image surveillance. It seems that in cases of disagreements, the rates of more accurate interpretation are well balanced between imaging specialists and the MTB.Trial registrationISRCTN16281786, Date 23. February 2017.

We report a case of concomitant metastasis in the nasal tip and suspected buttocks metastasis secondary to lung cancer, who complained of repeated cough and white sputum for 6 months. Diagnose: Primary lung cancer was diagnosed by bronchoscopy and biopsy, lesion on nasal tip was confirmed by biopsy. Furthermore, PET-CT scan identified the untouchable buttocks lesion that could have been easily missed. Interventions: This patient refused systemic treatments, but he chose traditional Chinese medicine at home. Outcomes: He died 6 months after the diagnosis. Lessons: The possibility of metastasis of primary cancers...

Rationale: Neuroendocrine tumors (NETs) of the lung account for 5% of all cases of lung cancer, which itself is the leading cause of cancer-related death worldwide. In accordance to its rarity, only few cell lines of NETs exist, which even often lack key characteristics of the primary tumor, making it difficult to study underlying molecular mechanisms. Patient concerns: The patient reported in this case is a 71-year old woman, which never smoked but suffered under dry cough. diagnoses: Chest CT-scan showed a paracardiac nodule of the lingula with 2 × 1.8 cm in diameter. Interventions: The detected paraca...

Proc IEEE Int Symp Biomed Imaging. 2018 Apr;2018:228-231 Authors: Zhong Z, Kim Y, Zhou L, Plichta K, Allen B, Buatti J, Wu X Abstract Positron emission tomography and computed tomography (PET-CT) dual-modality imaging provides critical diagnostic information in modern cancer diagnosis and therapy. Automated accurate tumor delineation is essentially important in computer-assisted tumor reading and interpretation based on PET-CT. In this paper, we propose a novel approach for the segmentation of lung tumors that combines the ...

AbstractOur knowledge about the incidence of pulmonary embolism (PE) and the performance of age adjusted D-dimers (Dd) cutoff amongst patients with lung cancer (LC) and suspected PE, remains limited. We retrospectively analyzed all clinically suspected patients who underwent computed tomography pulmonary angiography (CTPA) in a tertiary hospital during a 19  month period. Cancer diagnosis was established using ICD10 code. Eligible for Dd analysis were those tested up to 24 h prior to the scan. We analyzed 2549 patients (54.6% males, median age 68.8 years, IQR 57–78), 15.8% had active LC and 5.4% other ...
