  • Research progress on autoantibody liquid biopsy and AI-based radiomics in the diagnosis and treatment of non-small cell lung cancer

    Lung cancer has the highest incidence and mortality rates among malignant tumors both in China and worldwide, with approximately 85% of cases being non-small cell lung cancer (NSCLC). In the diagnosis and treatment of lung cancer, conventional imaging and tissue biopsy are often limited by insufficient sensitivity or invasive risks, making it difficult to meet the demands of future precision medicine. In recent years, artificial intelligence (AI)-based radiomics and autoantibody-based liquid biopsy have developed rapidly and have become major research focuses. AI radiomics significantly improves the accuracy of traditional imaging diagnosis by autonomously learning from large-scale imaging databases. Autoantibody liquid biopsy, on the other hand, utilizes tumor-associated autoantigens and antibodies as biomarkers, offering the advantages of being non-invasive, precise, efficient, and capable of reflecting spatiotemporal tumor heterogeneity, thereby demonstrating great potential in NSCLC diagnosis and treatment. This review summarizes recent research advances in autoantibody liquid biopsy and AI radiomics for the management of lung cancer.

  • Value of Intraoperative Ultrasound Guided Precise Tru-Cut Biopsy for Diagnosis of Solid Pancreatic Masses

    Objective To explore the value of pathologic diagnosis for pancreatic head mass by using recise Tru-cut biopsy under intraoperative ultrasound guided. Methods Twenty-eight patients with solid pancreatic masses in People’s Hospital of Suqian,Affiliated Hospital Xuzhou Medical College from August 2010 to August 2011 were performed precise Tru-cut biopsy under intraoperative ultrasound guided. In all patients of 28 cases, male 20 cases and female 8 cases, the male-to-female ratio was 5∶2. The patients’ age was 34-78 years old(mean age: 64 years old). Twenty-eight patients were divided into three groups based upon the greatest dimension of the masses as follows:equal or less than 1.5 cm (group S, 5 cases), 1.5-3.0cm (group M, 7 cases), and greater than 3.0cm (group L, 16 cases). Three needlepasses in each mass were performed. The results of postoperative pathologic findings were compared with specimens in paraffin sections. Results In all cases of 28, the diagnostic coincidence rate was 100%, there were no false positive finding and false negative. The coincidence ratio for pathological diagnosis of tissues with only 1 strip sample (1/3), only 2 strip samples (2/3), and with 3 strip samples (3/3) were 3/5, 2/5, and 0/0, respectivly in S group, 0/0, 5/7, and 2/7, respectivly in M group, and 0/0, 4/16, and 12/16, respectivly in L group. The false negative rate of single strip sample in S group and M group was higher than that in L group (χ2=9.833,P=0.002). There was false negative finding with master single test in small focus of infection.

  • Comparison of diagnostic accuracy, sampling satisfaction, and incidence of complications between ultrasound-guided core needle biopsy and fine needle aspiration biopsy of thyroid nodules: a meta-analysis

    ObjectiveTo compare the diagnostic accuracy, sampling satisfaction, and safety of ultrasound-guided core needle biopsy (CNB) and fine needle aspiration biopsy (FNA) for thyroid nodules.MethodsThe databases of PubMed, Medline, Web of Science, Cochrane Library, Wanfang, CNKI, and CBM were searched to collect the relevant studies on the diagnostic performance, sampling satisfaction, and safety of ultrasound-guided CNB and FNA for thyroid nodules. Revman 5.3 and Stata 15 software were used for meta-analysis.ResultsA total of 24 studies involving 25 388 patients were included. Meta analysis showed that: compared with CNB, FNA had poor diagnostic accuracy [OR=0.26, 95%CI (0.15, 0.46), P<0.000 01], poor sampling satisfaction [OR=0.20, 95%CI (0.12, 0.33), P<0.000 01], lower incidence of total complications [OR=0.28, 95%CI (0.16, 0.50), P<0.000 1], and lower incidence of bleeding after biopsy [OR=0.62, 95%CI (0.48, 0.81), P=0.000 3]. However, there was no significant difference in the pain score [WMD=–0.21, 95%CI (–0.57, 0.15), P=0.26] between the two groups. Subgroup analysis showed that there was no significant difference in the accuracy of biopsy diagnosis of thyroid nodules with diameter less than 10 mm between the two groups [OR=0.52, 95%CI (0.15, 1.81), P=0.30], however, the accuracy of CNB in the diagnosis of thyroid nodules with diameter ≥ 10 mm was still better than FNA [OR=0.26, 95%CI (0.12, 0.56), P=0.000 5].ConclusionsCompared with FNA, ultrasound-guided CNB has a certain advantages in sampling satisfaction and the diagnosis accuracy of thyroid nodules with diameter ≥ 10 mm. CNB is better than FNA, but will bring higher risk of complication.

  • Clinicopathological analysis of 25 patients with pulmonary alveolar proteinosis

    ObjectiveTo explore the clinicopathological features of pulmonary alveolar proteinosis (PAP).MethodsA total of 25 patients with PAP who were pathologically diagnosed in West China Hospital of Sichuan University from 2014 to 2018 were collected as the study subjects.ResultsThe 25 patients with PAP were 18–73 years old, with an average age of (42.52±15.79) years. There were 20 males and 5 females. The most common type was autoimmune PAP (15 cases), and secondary PAP (10 cases) were found in patients with pneumonia, tuberculosis, nephrotic syndrome, and pneumoconiosis. The common clinical symptoms of PAP were cough (24 cases), expectoration (20 cases), and progressive difficulty in breathing (11 cases of shortness of breath and 5 cases of dyspnea). The chest CT manifestations included double lung grinding (19 cases), grid-like changes (11 cases), and map-like changes (3 cases). Periodic acid-schiff (PAS) staining and post-digestion PAS staining double positive lipoprotein-like deposits was observed in lung biopsy (in the alveolar cavity) and/or alveolar lavage fluids.ConclusionsPAP has no characteristic clinical symptoms and a long diagnosis period. Clinicians should combine clinical signs, imaging features, and lung biopsy and/or alveolar lavage fluid PAS staining and post-digestion PAS staining to confirm the diagnosis.
