  • Research progress on the application of artificial intelligence in the pathology and prognosis of non-small cell lung cancer

    Non-small cell lung cancer is the main cause of cancer death in the world, and its incidence is increasing year by year, seriously endangering human health. Early non-small cell lung cancer is generally difficult to be detected based on symptoms and signs. Therefore, accurate pathological diagnosis and accurate prediction of prognosis are crucial for formulating the best treatment plan for non-small cell lung cancer patients and improving their survival. The application of artificial intelligence in the diagnosis and treatment of non-small cell lung cancer has shown good performance and great potential effect. This paper introduces the research progress of artificial intelligence in predicting the classification, staging, genomics and prognosis of non-small cell lung cancer.

  • Clinical effect analysis of three-port Da Vinci robot-assisted radical resection of lung cancer

    ObjectiveTo investigate the clinical effect of three-port Da Vinci robot-assisted radical resection of lung cancer. MethodsThe clinical data of patients who underwent Da Vinci robot-assisted radical resection of lung cancer in the Second Department of Thoracic Surgery, the First Affiliated Hospital of Xiamen University from April 2021 to March 2022 were retrospectively analyzed. According to the number of surgical ports, they were divided into two groups: a three-port group (three-port Da Vinci robot-assisted radical resection of lung cancer), and a four-port group (traditional Da Vinci robot-assisted radical resection of lung cancer). The operation time, intraoperative bleeding, lymphadenectomy, total thoracic drainage, extubation time, postoperative complications and postoperative pain of the two groups were compared and analyzed. ResultsA total of 58 patients were included, including 19 males and 39 females, aged 31-79 years. There were 21 patients in the three-port group, and 37 patients in the four-port group. The visual analogue scores on the first and third day after the operation were 4.33±1.20 points and 2.24±0.77 points in the three-port group, and 5.11±1.22 points and 2.78±1.06 points in the four-port group, and there were statistical differences between the two groups (P<0.05). There was no significant difference between the two groups in terms of operation time, intraoperative bleeding, lymph node dissection, postoperative thoracic drainage, time of thoracic tube insertion or postoperative complications (P>0.05). ConclusionThree-port Da Vinci robot-assisted radical resection of lung cancer can reduce the postoperative pain without increasing the operation difficulty and complications, and can be widely used in the clinical practice.

  • Clinical and pathological characteristics analysis of highly suspected malignant benign pulmonary nodules

    Objective To discuss the main pathological types and imaging features of pulmonary nodules highly suspected to be malignant in clinical practice but pathologically confirmed to be benign. Method A retrospective analysis was conducted on the clinical data of the patients with pulmonary nodules, who were initially highly suspected of malignancy but were pathologically confirmed as benign, treated at the First Affiliated Hospital of Xiamen University from December 2020 to April 2023. Based on the results of preoperative discussions, the patients were divided into a benign group and a suspicious malignancy group. Results Finally, 232 patients were collected, including 112 males and 120 females, with an average age of 51 years. There were 127 patients in the benign group, and 105 patients in the suspicious malignancy group. There was no statistical difference in age, gender, symptoms, smoking history, and tumor history between the two groups (P>0.05). However, there were statistical differences in nodule density, CT values, margins, shapes, andmalignant signs between the two groups (P<0.05). The analysis showed that in suspiciously malignant pulmonary nodules, the solid group was mainly characterized by collagen nodules and fibrous tissue hyperplasia (33.3%), tuberculosis (20.3%), and fungal infection (18.5%), while the non-solid group was primarily composed of collagen nodules and fibrous tissue hyperplasia (39.2%) and atypical adenomatous hyperplasia (17.6%). ConclusionThe benign pulmonary nodules suspected of malignancy are pathologically characterized by the presence of collagen nodules and fibrous tissue hyperplasia, tuberculosis, atypical adenomatous hyperplasia, and fungal infections. In terms of imaging features, they typically present as non-solid nodules, accompanied by signs of malignancy such as spiculation, lobulation, cavitation, and pleural retraction.

  • Expression and prognostic factors analysis of CYFRA21-1, CEA, and Ki67 in non-small cell lung cancer

    Objective To explore the value of preoperative detection of soluble fragments of cytokeratin-19 (CYFRA21-1), carcinoembryonic antigen (CEA), and postoperative detection of nuclear proliferation associated antigen Ki67 in prognostic evaluation of non-small cell lung cancer patients. Methods The clinicopathological data and follow-up results of patients with non-small cell lung cancer treated in the Department of Thoracic Surgery of the First Affiliated Hospital of Xiamen University in 2017 were collected. CYFRA21-1>3.39 ng/mL was defined as positive, and CEA>5 ng/mL was defined as positive. The receiver operating characteristic curve (ROC curve) of Ki67 expression level was drawn. The maximum area under the curve (AUC) was the cutoff value of Ki67 expression level, and the Ki67 expression level greater than its cutoff value was defined as positive. Cox regression analysis was used to determine the independent risk factors for poor prognosis in patients with non-small cell lung cancer. Results Finally 248 patients were collected, including 125 males and 123 females, with a median age of 61 years (ranging from 30 to 81 years) at the time of surgery. Univariate analysis showed that positive CYFRA21-1, high expression of Ki67, positive CEA, age≥60 years at operation, distant metastasis, lymph node metastasis, maximum tumor diameter>3 cm, and TNM stage Ⅲ were associated with poor prognosis in patients with non-small cell lung cancer. When combined detection of preoperative tumor markers and postoperative Ki67, the prognosis of all negative patients was the best, and that of all positive patients was the worst. Cox regression analysis showed that positive CEA+positive CYFRA21-1+high expression of Ki67 was an independent risk factor for poor prognosis in patients with non-small cell lung cancer (P<0.05). Conclusion The combined detection of preoperative serum CYFRA21-1, CEA, and postoperative Ki67 has important value in evaluating the prognosis of non-small cell lung cancer patients.
