With the continuous advancements in immunotherapy and targeted therapy, there have been significant changes in the treatment management and surgical resection assessment of locally advanced lung cancer. In October 2024, the Society of Thoracic Surgeons (STS) published the “STS expert consensus on the multidisciplinary management and resectability of locally advanced non-small cell lung cancer”. This expert consensus aims to provide the latest insights on the assessment of resectability and multidisciplinary management of locally advanced lung cancer, focusing on three key areas: neoadjuvant (including perioperative) therapy, adjuvant therapy, and the overall management approach. This article aims to interpret the consensus, with the intention of introducing the latest perspectives of the STS consensus to thoracic surgeons. It seeks to provide a reference for the rational implementation of surgical resection and multidisciplinary management of non-small cell lung cancer in China, as well as for the standardization of comprehensive treatment models.
ObjectiveTo validate the use of key point matrix technology based contactless automatic measurement for evaluation of joint motion of hand. Methods Thirty-three volunteers were enrolled to evaluate the extension and flexion of hand joints between May 2021 and November 2021. There were 20 males and 13 females, the age ranged from 16 to 70 years with an average of 30.2 years. The extension angles of 14 joints of 5 fingers (including hyperextension) and the flexion angles of 12 joints of 4 fingers (excluding thumb) of volunteers were measured by key point matrix technology and manual goniometer, respectively. Then 5 participants and repeated measurement experiment were employed to test the system repeatability and accuracy; 28 participants and paired measurement experiment were employed to test the system accuracy. Results The average repeatability of finger joint motion measured by the key point matrix technology was 1.801° (extension) and 7.823° (flexion), respectively. Compared with manual measurement, the average differences of each finger joint measured by the key point matrix technology were 3.225° in extension and 14.145° in flexion, respectively. The key point matrix technology based contactless automatic evaluation system offered excellent consistency with the manual goniometers (ICC=0.875). While most of the consistency with manual goniometer of individual joints were at moderate levels (median of ICC, 0.440). The correlation coefficients between the measurement results of the two methods were mainly positive in the extension of the joint (P<0.05) and negative in the flexion of the joints (P<0.05). ConclusionThe key point matrix technology based contactless automatic evaluation provides sufficient measurement repeatability and accuracy in evaluation for the joint motion of hand.
