Image analysis in posttreatment non-small cell lung cancer surveillance: specialists ’ interpretations reviewed by the thoracic multidisciplinary tumor board

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.

ConclusionsSegment location, ground glass opacity proportion and absence of hilar lymph nodes involvement are reliable predictors of node-negative status in specific mediastinal regions. Based on these findings, we propose a new selective mediastinal lymph node dissection strategy for NSCLC.

ConclusionsSUVm does not correlate with glycolytic metabolism in human NSCLC, but does correlate with the proliferation index, suggesting that SUVm predicts glucose use by pathways other than glycolysis. These pathways may offer alternative therapeutic targets, including biosynthetic pathways required for cell proliferation. The research techniques in this study offer the opportunity to understand the relationships between SUVm, tumor metabolism, and therapeutic vulnerabilities in human NSCLCs.

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.

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...

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...

There are limited data on the clinical efficiency of afatinib in non ‐small cell lung cancer (NSCLC) patients with uncommon epidermal growth factor receptor (EGFR) mutations. Moreover, the efficacy and safety of afatinib in elderly patients with these mutations has not been established. Here, we describe a case of successful treatment of a patient aged>80  years with lung adenocarcinoma positive for the uncommon EGFR L861Q mutation with low‐dose afatinib. An 83‐year‐old woman presented with cough and dyspnea. A chest computed tomography (CT) scan revealed tumors in the left upper lobe, left pleural effusi...

AbstractWhile molecular imaging with positron emission tomography or single-photon emission computed tomography already reports on tumour molecular mechanisms on a macroscopic scale, there is increasing evidence that there are multiple additional features within medical images that can further improve tumour characterization, treatment prediction and prognostication. Early reports have already revealed the power of radiomics to personalize and improve patient management and outcomes. What remains unclear is how these additional metrics relate to underlying molecular mechanisms of disease. Furthermore, the ability to deal w...

Accurate assessment of mediastinal lymph node (LN) involvement is of paramount importance during treatment decision-making for patients with non-small cell lung cancer (NSCLC) who lack distant metastases [1]. The initial investigation usually features computed tomography (CT), and positron emission tomography integrated with CT (PET-CT). Given the low pooled diagnostic sensitivities of chest CT (55%) and PET-CT (62%), abnormal findings evident from noninvasive testing should be examined via invasive mediastinal staging such as endosonography or mediastinoscopy [2].

Improved local control attributes to improved overall survival (OS) in locally advanced non-small cell lung cancer (LA-NSCLC) treated with concurrent chemoradiotherapy (CCRT) [1]. Many adjustments of chemo- and radiotherapy (RT) regimens have been explored to increase outcome [1]. One such adjustment is the combination of daily low dose cisplatin with hypofractionated radiotherapy, which has been explored in several EORTC-trials and in a Dutch randomized phase II Raditux-trial (NTR2230) investigating the addition of Cetuximab to CCRT [2 –4].

CONCLUSION: Early post-treatment PET-metrics are associated with treatment outcome in LA-NSCLC patients treated with chemoradiotherapy. Both volumetric and intensity PET-metrics are useful, but more for the primary tumor than for lymph nodes. PMID: 31767474 [PubMed - as supplied by publisher]
