Humanistic Continuing Care Via WeChat for Patients Undergoing Thermal Ablation of Papillary Thyroid Carcinoma

The goal of this clinical trial is to test whether human-centered nursing care lowers emotional distress and improves quality of life for people who are awake during thyroid thermal ablation. The procedure uses local anesthesia, so participants remain awake and may feel tense. Human-centered care focuses on emotional support, clear communication, comfort, and follow-up, and it may improve the experience and recovery for patients. The main questions are: Does human-centered nursing care reduce emotional distress levels in patients undergoing thyroid thermal ablation? Does human-centered nursing care improve patient quality of life after thyroid thermal ablation? If there is a comparison group: Researchers will compare human-centered nursing care to usual nursing care to see if human-centered care leads to lower emotional distress and higher quality of life. Participants will: Receive either human-centered nursing care or usual nursing care. Complete questionnaires before, during, and after the procedure to measure emotional distress, quality of life, pain, and satisfaction with care. Have their vital signs and quality of life tracked during and after the procedure. Have their adherence to care plans and any complications monitored. The main outcomes are emotional distress levels and quality of life. Other outcomes include pain and vital signs during the procedure, satisfaction with care, and complication rates. Results may guide better care for people undergoing small, minimally invasive treatments while awake.

Multimodal Deep Learning for Lymph Node Metastasis in Thyroid Cancer

Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy in clinical practice, accounting for approximately 85% of all thyroid malignancies. The occurrence of cervical lymph node metastasis further increases the risk of local tumor recurrence and distant metastasis, thereby reducing patient survival rates. Pathological examinations reveal that approximately 30-80% of PTC patients have lymph node metastasis. Early detection of metastatic lymph nodes and the development of individualized treatment plans are crucial for improving patient prognosis. Currently, the primary method for diagnosing lymph node metastasis is ultrasound-guided fine-needle aspiration, but its accuracy is limited by sample quality and carries a risk of false-negative results. In recent years, deep learning technology has demonstrated significant potential in the field of medical image analysis. Therefore, the investigators aim to develop a deep learning model based on neck ultrasound to more accurately predict lymph node metastasis.

Comparative Study of Transaxillary Robotic Thyroidectomy With MRND Versus Conventional Open Surgery in N1b PTC

Thyroid cancer is one of the most common malignant tumors in women, ranking seventh in the United States and fourth in China. Papillary thyroid carcinoma is the most common pathological type (about 85% to 90% of thyroid cancers), and lateral cervical lymph node metastasis can reach 0.6-37.5% at diagnosis. For papillary thyroid cancer with lateral cervical lymph node metastasis, the 2015 ATA Guidelines in the United States recommend surgical resection and neck lymph node dissection as the primary treatment. Traditional cervical lymph node dissection often leaves obvious scars in the neck, which seriously affects the postoperative quality of life of patients. The previous studies have shown that endoscopy-assisted surgery with external cervical approach can achieve oncologic effects similar to traditional open surgery in the treatment of N1b papillary thyroid cancer, and can obtain better aesthetic results. However, endoscopic surgery still has some shortcomings, such as poor exposure of some surgical areas and difficult operation. Since November 2016, the investigators tried to apply modified transaxillary robotic-assisted surgery technology to the treatment of thyroid papillary carcinoma in China. The preliminary study included 30 patients, and the results showed that robot-assisted surgery via combined transaxillary-retroaural approach in the treatment of N1b papillary thyroid carcinoma achieved a good oncologic effect (5-year overall survival rate was 100.0%). As the surgical techniques improved, now the investigators can complete robotic-assisted lateral neck lymph node dissection via single-incision transaxillary approach. However, there is still a lack of high-quality evidence on the long-term oncologic outcome and quality of life of this procedure. In this study, a prospective, multi-center, randomized controlled study was conducted to compare the safety, long-term oncologic outcomes and postoperative quality of life of the robot-assisted surgery via single-incision transaxillary approach and open surgery in the treatment of N1b papillary thyroid cancer, which may provide an alternative for the patients with N1b papillary thyroid cancer.

Active Surveillance and Surgery Outcomes in Low Risk Papillary Thyroid Cancer

This is a prospective, observational, multi-center study examining the long-term outcomes of patients with small, low risk papillary thyroid cancer who offered the choice of active surveillance (close follow-up to monitor for potential disease progression) or immediate surgery.

Diagnostic Accuracy of Fluorodeoxyglucose-18 PET in the Evaluation of RPTC With Patient's Raised Thyroglobulin Level

This research will employ cross-sectional analytical to determine diagnostic accuracy of Flourodeoxyglucose-18 Positron Emission Computed Tomography in the evaluation of Recurrent Papillary Thyroid Carcinoma with patient's raised Thyroglobulin level in Lahore.

RET-US Study - Ultrasound-Based Prediction of RET Alterations and Lateral-Neck Metastasis in Thyroid Cancer

Why is this study being done? RET gene alterations occur in only 5-10 % of papillary thyroid cancers, but they can change how surgeons treat the disease. Gene testing is costly and not always performed, so many RET-positive tumours are missed. Researchers have built a computer program (artificial-intelligence or "AI" model) that reads routine thyroid ultrasound images and predicts whether the tumour carries a RET alteration and whether the cancer has already spread to lymph-nodes in the side of the neck. What will happen in this study? About 800 adults who are scheduled for thyroid-cancer surgery will take part. Each participant will: * have a standard pre-operative ultrasound exam (no extra scanning time), * give a routine fine-needle sample for a 14-gene panel test (results in 24 h), and * allow the AI model to analyse the ultrasound images in the background. Doctors making treatment decisions will not see the AI result. After surgery, the research team will compare the AI predictions with the gene-panel result and the final pathology report. Main goal: To find out how accurately the AI model detects RET alterations. Secondary goals: To measure the model's ability to predict lymph-node spread, and to compare costs between ultrasound-only prediction and full gene testing. Benefits and risks: Participants will receive the current standard of care; there is no added risk beyond the usual ultrasound and needle biopsy. The study could lead to faster, less expensive ways to identify high-risk thyroid cancers in the future.
