Summary: The incidence of papillary thyroid cancer (PTC) has been on the rise in recent years, and 20%-50% of PTC patients will have lymph node metastasis. Lymph node involvement in PTC patients is usually related to the recurrence of PTC after surgery, and 30% of patients recur without lymph node dissection, with the risk of central cervical lymph node metastasis being the greatest, so it seems to be a good choice to perform lymph node dissection on patients after thyroidectomy, but in fact, there are controversies at home and abroad as to whether to perform lymph node dissection or not. The 2021 Chinese Society of Clinical Oncology (CSCO) guidelines for the diagnosis and treatment of differentiated thyroid cancer state that prophylactic central lymph node dissection (PCND) may increase the incidence of postoperative complications, but due to the high metastatic rate of PTC and the ability of PCND to effectively prevent recurrence and reoperation, countries in the East Asian region perform prophylactic lymph node dissection on almost all patients with PTC. However, for more countries in Europe and the United States, performing PCND has become a non-essential, individualized option. The aim of this study is to collect multifactorial data from more than 1,000 patients who have undergone previous thyroidectomy from 2021 to 2023, and to develop a novel scoring scale that can be used to individualize patients' scores based on a variety of factors prior to surgery, so that patients can be more accurately predicted to have lymph node metastasis and need prophylactic lymph node dissection prior to surgery, and patients who do not need dissection can avoid surgery. For patients who do not need lymph node dissection, complications caused by surgery can be avoided, while for patients who do have lymph node metastasis, recurrence of their cancer can be prevented. This will change the status quo of not being able to accurately determine the actual situation through simple preoperative examination or performing prophylactic lymph node dissection for all PTC patients.

Detailed description: 1. Patient characteristics: the inclusion criteria were as follows:1. patients with papillary thyroid cancer;2. minimum age of 16 years old and maximum age of 80 years old. Exclusion criteria:1. age less than 16 years old;2. postoperative pathology suggesting that there are other types of tumors, such as medullary carcinoma or undifferentiated carcinoma. 2,.Data collection: Investigators collected multifactorial data on about 1000 patients who had undergone previous thyroidectomy from 2021-2023, including gender, height, age, weight, BMI, diameter of the tumor in the primary focus, tumor limitation in the primary focus, lymph node metastasis, and tumor invasion, preoperative ultrasonographic manifestations, preoperative laboratory results, pathological results, and genetic testing results. From these, the available data were screened and retained for analysis. 3.Data analysis: According to the retained data after screening, classical machine learning algorithms will be used for feature selection to select the factors with greater correlation with the results, and then with the help of data visualization, the specific quantitative relationship between each factor and the results will be determined according to the distribution of the available data, and the quantitative scoring table will be created. 4. Clinical validation: The completed quantitative rating scale investigators will be validated in the clinic. Investigators will use the scale to score new patients to assess whether participants need prophylactic lymph node dissection, and then evaluate the accuracy of the quantitative scale according to the intraoperative or postoperative situation.
