An application of machine learning based on real-world data: Mining features of fibrinogen in clinical stages of lung cancer between sexes.

Ann Transl Med 2021 Apr;9(8):623

Department of Thoracic Surgery, The Affiliated Cancer Hospital of Nanjing Medical University & Jiangsu Cancer Hospital & Jiangsu Institute of Cancer Research, Jiangsu Key Laboratory of Molecular and Translational Cancer Research, Collaborative Innovation Center for Cancer Personalized Medicine, Nanjing, China.

Background: Lung cancer is the most threatening malignant tumor to human health and life. Using a variety of machine learning algorithms and statistical analyses, this paper explores, discovers and demonstrates new indicators for the early diagnosis of lung cancer and their diagnostic performance from large samples of clinical data in the real world.

Methods: By applying machine learning methods, including minimum description length (MDL), naive Bayesian (NB), K-means (KM), nonnegative matrix factorization (NMF), and decision tree (DT), based on large sample data of 2,502 patients, we built a classification model and systematically explored differences in fibrinogen levels in different clinical stages of lung cancer between the sexes.

Cancer 2021 May 10. Epub 2021 May 10.

Pathology Consultants, Westlake Village, California.

During the period from 1962 to 1977, several antigens, notably carcinoembryonic antigen and prostate-specific antigen, were discovered and entered clinical use. Ultrasonography, positron emission tomography scanning, and magnetic resonance imaging were introduced, and adjuvant radiation and chemotherapy after limited surgery became routine procedures. Radioimmunoassay and immunohistochemistry techniques were standardized. Read More

Endobronchial Seeding of Squamous Lung Carcinoma with Mediastinal Lymph Involvement Node after EBUS: A Case Report.

Ann Thorac Cardiovasc Surg 2021 May 8. Epub 2021 May 8.

Department of Pathology, Avicenne University Hospital, Paris 13 University, Bobigny, France.

In locally advanced non-small-cell lung cancer (NSCLC), mediastinal staging is the cornerstone of the therapeutic decision and echoendoscopy is the most practiced exam to assess the lymph node involvement. We describe a rare case of endobronchial involvement by cells originating from a metastatic lymph node after endobronchial ultrasound (EBUS). A 64-year-old man was diagnosed with a squamous cell lung cancer with mediastinal nodal involvement proven by EBUS. Read More

Electrospray Mediated Localized and Targeted Chemotherapy in a Mouse Model of Lung Cancer.

Front Pharmacol 2021 20;12:643492. Epub 2021 Apr 20.

Department of Pulmonary Medicine, University Hospital Bern, Bern, Switzerland.

An advanced stage, centrally localized invasive tumor is a major cause of sudden death in lung cancer patients. Currently, chemotherapy, radiotherapy, laser ablation, or surgical resection if possible are the available state-of-the-art treatments but none of these guarantee remedy or long-term relief and are often associated with fatal complications. Allowing localized chemotherapy, by direct and confined drug delivery only at the tumor site, could be a promising option for preoperative down staging or palliative therapy. Read More

Transbronchial mediastinal cryobiopsy in the diagnosis of mediastinal lesions: a randomised trial.

Eur Respir J 2021 May 6. Epub 2021 May 6.

Department of Respiratory Disease, Xinqiao Hospital, Third Military Medical University, Chongqing, China.

Background: Guidelines recommend endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) as an initial investigation technique for mediastinal nodal staging in lung cancer. However, EBUS-TBNA can be limited by the inadequacy of intact tissues, which might restrict its diagnostic yield in mediastinal lesions of certain etiologies. We have previously shown that EBUS-guided transbronchial mediastinal cryobiopsy can provide intact samples with greater volume. Read More

Cutaneous Lesion of the Nose as Initial Presentation of Esophageal Adenocarcinoma.

Anticancer Res 2021 May;41(5):2485-2488

Division of Medical Oncology, Allegheny General Hospital, Pittsburgh, PA, U.S.A.

Background/aim: Cutaneous manifestations of disease are exceedingly rare and commonly overlooked in clinical practice. Allergies or contact dermatitis, autoimmune disease or skin cancer are the most common conditions typically associated with skin lesions. Rarely, cutaneous lesions may be the first sign of internal malignancy, or even resemble recurrent disease in those with history of cancer. Read More

Predicting Lymph Node Metastasis in Non-Small Cell Lung Cancer: Prospective External and Temporal Validation of the HAL and HOMER Models.

Chest 2021 Apr 28. Epub 2021 Apr 28.

Department of Pulmonary Medicine, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Background: Two models, the Help with the Assessment of Adenopathy in Lung cancer (HAL) and Help with Oncologic Mediastinal Evaluation for Radiation (HOMER), were recently developed to estimate the probability of nodal disease in non-small cell lung cancer (NSCLC) patients as determined by endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA). The objective of this study was to prospectively externally validate both models at multiple centers.

Research Question: Are the HAL and HOMER models valid across multiple centers?

Study Design And Methods: This multicenter prospective observational cohort study enrolled consecutive patients with PET-CT clinical-radiographic stage T1-3, N0-3, M0 NSCLC undergoing EBUS-TBNA staging. Read More

Performance insights of endobronchial ultrasonography (EBUS) and mediastinoscopy for mediastinal lymph node staging in lung cancer.

Lung Cancer 2021 Apr 7. Epub 2021 Apr 7.

Department of Pulmonary Medicine, Canisius-Wilhelmina Hospital, Weg Door Jonkerbos 100, 6532SZ, Nijmegen, the Netherlands.

Introduction: Endobronchial Ultrasonography (EBUS) and mediastinoscopy are used for mediastinal lymph node staging in patients with suspected non-small cell lung carcinoma (NSCLC). In our hospital, confirmatory mediastinoscopy has been largely abandoned, which may reduce the number of surgical interventions and health care costs. This study provides insight into EBUS and mediastinoscopy performance in patients with proven NSCLC from January 2007 until January 2019. Read More

A Canadian Perspective on the Challenges for Delivery of Curative-Intent Therapy in Stage III Unresectable Non-Small Cell Lung Cancer.

Curr Oncol 2021 Apr 24;28(3):1618-1629. Epub 2021 Apr 24.

Department of Radiation Oncology, BC Cancer Agency, Surrey, BC V2V 1Z2, Canada.

Stage III non-small cell lung cancer (NSCLC) comprises a highly heterogenous group of patients with regards to patient fitness and tumour size and distribution, resulting in a wide range of treatment goals and therapy options. Curative-intent multimodality treatment should be considered in all patients with stage III NSCLC. For patients with unresectable disease who are fit, have adequate lung function, and have a disease that can be encompassed within a radical radiation volume, concurrent chemoradiation therapy (cCRT) is the standard of care and can produce cure rates of 20-30%.

Future Perspectives on the TNM Staging for Lung Cancer.

Cancers (Basel) 2021 Apr 17;13(8). Epub 2021 Apr 17.

Department of Thoracic Surgery, Hospital Universitari Mútua Terrassa, University of Barcelona, Plaza Dr. Robert 5, 08221 Terrassa, Spain.

Since its conception by Pierre Denoix in the mid-20th century, the tumor, node, and metastasis (TNM) classification has undergone seven revisions. The North American database managed by Clifton Mountain was used to inform the 2nd to the 6th editions, and an international database collected by the International Association for the Study of Lung Cancer, promoted by Peter Goldstraw, was used to inform the 7th and the 8th editions. In these two latest editions, it was evident that the impact of tumor size was much greater than it was suggested in previous editions; that the amount of nodal disease had prognostic relevance; and that the number and location of the distant metastases had prognostic implications.
