Awareness and Use of ChatGPT and Large Language Models: A Prospective Cross-sectional Global Survey in Urology

BACKGROUND

Since its release in November 2022, ChatGPT has captivated society and shown potential for various aspects of health care.

OBJECTIVE

To investigate potential use of ChatGPT, a large language model (LLM), in urology by gathering opinions from urologists worldwide.

DESIGN, SETTING, AND PARTICIPANTS

An open web-based survey was distributed via social media and e-mail chains to urologists between April 20, 2023 and May 5, 2023. Participants were asked to answer questions related to their knowledge and experience with artificial intelligence, as well as their opinions of potential use of ChatGPT/LLMs in research and clinical practice.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Data are reported as the mean and standard deviation for continuous variables, and the frequency and percentage for categorical variables. Charts and tables are used as appropriate, with descriptions of the chart types and the measures used. The data are reported in accordance with the Checklist for Reporting Results of Internet E-Surveys (CHERRIES).

RESULTS AND LIMITATIONS

A total of 456 individuals completed the survey (64% completion rate). Nearly half (47.7%) reported that they use ChatGPT/LLMs in their academic practice, with fewer using the technology in clinical practice (19.8%). More than half (62.2%) believe there are potential ethical concerns when using ChatGPT for scientific or academic writing, and 53% reported that they have experienced limitations when using ChatGPT in academic practice.

CONCLUSIONS

Urologists recognise the potential of ChatGPT/LLMs in research but have concerns regarding ethics and patient acceptance. There is a desire for regulations and guidelines to ensure appropriate use. In addition, measures should be taken to establish rules and guidelines to maximise safety and efficiency when using this novel technology.

PATIENT SUMMARY

A survey asked 456 urologists from around the world about using an artificial intelligence tool called ChatGPT in their work. Almost half of them use ChatGPT for research, but not many use it for patients care. The resonders think ChatGPT could be helpful, but they worry about problems like ethics and want rules to make sure it's used safely.

Prevalence of High-Risk Prostate Cancer Metastasis to Cloquet's Ilioinguinal Lymph Node

PURPOSE

Cloquet's node, located at the junction between the deep inguinal nodes and the external iliac chain, is easily accessible and commonly excised during pelvic lymph node dissection for prostate cancer. However, we hypothesize that Cloquet's node is not part of lymphatic metastatic spread of prostate cancer.

MATERIALS AND METHODS

Between September 2016 and June 2019, 105 consecutive patients with high-risk prostate cancer (cT3a or Grade Group 4/5, or prostate specific antigen >20 ng/ml) underwent a laparoscopic radical prostatectomy and pelvic lymph node dissection. First, Cloquet's node was identified, retrieved and submitted separately to pathology as right and left Cloquet's node. Next, a pelvic lymph node dissection was completed including the external iliac, obturator fossa and hypogastric nodal packets. Each lymph node was cut into 3 mm slices which were separately embedded in paraffin, stained with hematoxylin and eosin, and examined microscopically.

RESULTS

The final analysis included 95 patients. In this high-risk population, the median number of nodes removed was 22 (IQR 18-29); 39/95 patients (41%) had lymph node metastasis. The median number of Cloquet's nodes removed was 2 (IQR 2-3). Cloquet's node was negative in all but 1 patient (1.1%), who had very high-risk features and high metastatic burden in the lymph nodes.

CONCLUSIONS

In high-risk prostate cancer, metastasis to the ilioinguinal node of Cloquet is rare. Given this low prevalence, Cloquet's node can be safely excluded from the pelvic lymph node dissection template.
