Ten recommendations for sarcoma surgery: consensus of the surgical societies based on the German S3 guideline "Adult Soft Tissue Sarcomas"

Comparing ChatGPT-3.5 and ChatGPT-4's alignments with the German evidence-based S3 guideline for adult soft tissue sarcoma

Clinical reliability assessment of large language models is necessary due to their increasing use in healthcare. This study assessed the performance of ChatGPT-3.5 and ChatGPT-4 in answering questions deducted from the German evidence-based S3 guideline for adult soft tissue sarcoma (STS). Reponses to 80 complex clinical questions covering diagnosis, treatment, and surveillance aspects were independently scored by two sarcoma experts for accuracy and adequacy. ChatGPT-4 outperformed ChatGPT-3.5 overall, with higher median scores in both accuracy (5.5 vs. 5.0) and adequacy (5.0 vs. 4.0). While both versions performed similarly on questions about retroperitoneal/visceral sarcoma and gastrointestinal stromal tumor (GIST)-specific treatment as well as questions about surveillance, ChatGPT-4 performed better on questions about general STS treatment and extremity/trunk sarcomas. Despite their potential as a supportive tool, both models occasionally offered misleading and potentially life-threatening information. This underscores the significance of cautious adoption and human monitoring in clinical settings.

What is the Optimal Treatment Strategy after Sarcoma R2 Surgery?

OPINION STATEMENT

Soft tissue sarcomas (STS) are rare tumours of mesenchymal origin, most commonly occurring in the extremity but also in the retroperitoneum. The curative treatment for STS is radical surgery with wide margins, in some cases in combination with perioperative radiotherapy and chemotherapy. Nonradical resection (R2) of STS has been an emerging issue in recent decades, as optimal subsequent management remains debatable. Similarly, there is still no consensus on optimal surgical margins. Combining multiple treatment modalities in adjuvant therapy can achieve local and distant control in patients following surgery with positive margins. Patients who have undergone nonradical resection therefore require additional surgical interventions, and adjuvant radiotherapy resulting in a better prognosis but a higher number of complications. Following non-radical treatment, patients with limb and trunk wall sarcomas and retroperitoneal sarcomas should also undergo increased oncological surveillance. Given the potential issues that may emerge in such clinical situations, it is crucial to up-date the current guidelines to enhance the long-term prognosis of these patients.

Quality assessment of online osteosarcoma-related videos in Mainland China: A cross-sectional study

BACKGROUND

Information about orthopedics diseases on the Internet has not been extensively assessed. Our purpose was to evaluate the quality of online information of osteosarcoma on current video-sharing platforms in mainland China.

METHOD

TikTok and Bilibili were independently queried from June to July 2023 by four independent researchers using the Microsoft Edge web browser. Information about the videos and creators was recorded, and descriptive analyses were conducted.

RESULTS

After data extraction, a total of 95 videos were included, in which 43 videos were uploaded by certified doctors (45.3%), with 35 videos (36.8%) uploaded by certified orthopedic surgeons. Of the content of these videos, 78.9% were introduction (n = 75), 64.2% were on professional knowledge (n = 61), 28.4% were on treatment (n = 27), while 5.3% were on surgical techniques (n = 5). The mean DISCERN total score was 43.8 ± 13.4, and the mean JAMA score was 3.8 ± 0.3.

CONCLUSIONS

Videos about osteosarcoma on current video-sharing platforms were extensive, but were not comprehensive and professional. Although current online videos have the potential to improve public awareness on osteosarcoma, due to their quality and content, were not assessed to be good sources for medical education.
