Segmentectomy After Induction Therapy (SAINT)

The primary objective will be to determine the feasibility of performing a high-quality sublobar anatomic resection (segmentectomy) with R0 margin status on final pathology for patients who received induction therapy for NSCLC and are downstaged to ≤ycT1cN0M0 (TDi 3cm or less). T1c is tumor staging 1 and c stands for tumor is considered larger than 2cm but no larger than 3cm across; N0 is No regional lymph node metastasis; M0 is No distant metastasis.

Pre-incisional Infiltration With Ropivacaine Plus Triamcinolone for Relieving Postoperative Pain After Thoracoscopic Surgery

Video-assisted thoracoscopic surgery (VATS) is less invasive compared to traditional thoracotomy, but it is still reported that the incidence of acute pain following VATS exceeds 80%. Inadequate postoperative analgesia may trigger a series of adverse physiological stress responses, increase the occurrence of postoperative complications, and affect the rehabilitation process. If acute pain is not managed promptly and sufficiently, nearly one-quarter of patients may develop chronic pain, impacting normal life and sleep quality after discharge. Acute pain after VATS is mainly caused by the release of inflammatory mediators after soft tissue injury at the surgical site, which activates peripheral pain receptors and leads to abnormal action potentials transmitted along A δ and C fibers. Inflammatory mediators released from the soft tissues around incisions not only significantly alters the chemical microenvironment at the peripheral terminals of nociceptors, directly inducing pain, but also sensitizes afferent fibers, contributing to peripheral sensitization. Incisional infiltration is the simplest, safest, and most effective anesthesia method for preventing incision pain after laparoscopic surgery but even using long-acting local anesthetics, the effectiveness of postoperative analgesia can only last for a relatively short period of time. To improve the efficiency of local incision infiltration in postoperative analgesia, at least two issues need to be addressed: prolonging the duration of analgesia and reducing inflammation of nerve surrounding tissues. Numerous studies have shown that glucocorticoids not only can achieve anti-inflammatory and analgesic effects by inhibiting inflammatory cytokines and inflammatory responses but also can prolong the duration of action of local anesthetics. The investigators conducted a multicenter, prospective, randomized controlled clinical study to explore whether preemptive incisional infiltration with ropivacaine plus triamcinolone is superior to ropivacaine alone in relieving postoperative pain for adults undergoing VATS. The investigators also compare the effects of the two intervention measures on postoperative pain management, patient safety, and recovery quality.

Effect and Long-Term Outcomes of Indocyanine Green Fluorescence Imaging Method Versus Modified Inflation-Deflation Method in Identification of Intersegmental Plane（IMPLANE-0529）

This study is a multi-center, prospective, randomized controlled clinical trial. The purpose is to compare the difference of indocyanine green fluorescence imaging method and modified inflation-deflation method in identifying intersegmental plane in segmentectomy, and provide high-level evidence for the selection of intersegmental plane identification method in early NSCLC segmental resection.

Auricular Acupressure in Prehabilitation

Complementary medicine is recognized for its ability to enhance appetite, increase energy, reduce anxiety, decrease pain, and improve sleep, among many other benefits. Acupuncture is among the most frequent types of complementary medicine practiced in the US, and Medicare currently includes back pain as a reimbursable indication for this therapy. Acupuncture-related therapies may enhance efforts at prehabilitation in candidates for major lung resection.

Personalized Postoperative Pain Management Following Thoracic Surgery in Adults

The proposed research is an important extension of an ongoing perioperative personalized analgesia and intravenous opioid pharmacogenetic research. This research focuses on two of the most commonly used oral opioid analgesics, oxycodone, and methadone, in adults following thoracic surgery. Major inpatient thoracic surgeries (TS) for lung disease are common and extremely painful surgeries and are associated with sever post-surgical pain, high incidence of chronic post-surgical pain (CPSP), excess opioid use, costly immediate postoperative opioid adverse events (AEs), and long hospital stays. This study is aiming to develop proactive risk prediction algorithms for precision surgical pain relief in adult TS patients through comparison of actual clinical outcomes with standard of care to predicted outcomes based on personalized risk assessments.

Segmentectomy for Solid-dominant Lung Cancer

This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1025. The goal of this clinical trial is to confirm the theraputic effect of segmentectomy for solid-dominant invasive lung cancer with size of 2-3cm. The main questions it aims to answer are: * The 5-year disease-free survival of patients having solid-dominant invasive lung cancer with size of 2-3cm; * The post-operative lung function tests after receiving segmentectomy. Participants will receive segmentectomy as the surgical procedure.

Segmentectomy for Ground Glass-dominant Invasive Lung Cancer (ECTOP-1012)

This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1012. The goal of this clinical trial is to confirm the theraputic effect of segmentectomy for ground glass-dominant invasive lung cancer with size of 2-3cm. The main questions it aims to answer are: * The 5-year disease-free survival of patients having ground glass-dominant invasive lung cancer with size of 2-3cm; * The post-operative lung function tests after receiving segmentectomy. Participants will receive segmentectomy as the surgical procedure.
