Disease-Free Survival

This is a single site, non-randomized, open-label, long-term safety and efficacy follow-up study for Phase 1 studies that evaluate the safety and efficacy of CAR T cells: NCT05660369 (HCC# 22-175), NCT06026319 (HCC# 23-474) and NCT NCT07388277 (MGB# 2025P003179.

In the comprehensive treatment system for esophageal cancer, surgical resection combined with regional lymph node dissection remains the core component for achieving cure in patients with resectable esophageal squamous cell carcinoma (ESCC). The traditional surgical concept holds that the more thorough the lymph node dissection, the better. However, increasing basic and clinical evidence indicates that lymph nodes without metastasis-particularly tumor-draining lymph nodes-play an irreplaceable role in maintaining the host's anti-tumor immune response. Preclinical studies have found that radiation exposure to tumor-draining lymph nodes can impair the efficacy of radiotherapy combined with immunotherapy. In the surgical field, this shift in understanding has given rise to an important clinical question: in radical esophagectomy for esophageal cancer, is it possible to maximally preserve non-metastatic normal lymph nodes while ensuring complete removal of metastatic lymph nodes? If achievable, patients may not only benefit from reduced postoperative complications (such as chylothorax and recurrent laryngeal nerve injury) but also retain important immune organ function, providing a stronger basis for subsequent immunotherapy responses. Therefore, this study intends to conduct a multicenter, prospective, randomized controlled, non-inferiority trial in patients with cT1-3N0M0 esophageal squamous cell carcinoma who have not received neoadjuvant therapy, to evaluate the oncological safety of sentinel lymph node dissection based on the ICG near-infrared fluorescence imaging system in radical esophagectomy for esophageal cancer. During the study, ICG will be injected around the tumor under intraoperative gastroscopy guidance, followed by tracking of fluorescent lymph nodes using a thoracoscopic near-infrared camera. Professional thoracic surgeons will group and mark these lymph nodes for intraoperative frozen pathology. If intraoperative frozen section shows negative sentinel lymph nodes, patients will be randomized 1:1 into two groups: one group will undergo esophagectomy alone without further lymph node dissection, while the other group will undergo conventional lymph node dissection plus esophagectomy. The primary objective of this study is to evaluate the non-inferiority of ICG-guided sentinel lymph node dissection compared with conventional systematic lymph node dissection in terms of 3-year disease-free survival in patients with cT1-3N0M0 esophageal squamous cell carcinoma who have not received neoadjuvant therapy, thereby validating the oncological safety of the sentinel lymph node dissection strategy. Participants will: 1. Undergo minimally invasive ESCC surgery within 2 weeks of enrollment, including the 14th day. 2. Receive ICG injection around the tumor under intraoperative gastroscopy guidance during surgery. 3. Have perioperative, postoperative pathology, and complication information recorded. 4. Undergo standardized follow-up after surgery.

In this multiple-center phase II study, the aim is to evaluate the clinical outcome of reduced intensity conditioning regimen with fludarabine (150mg/m2), busulfan (6.4mg/kg) and melphalan (100mg/m2) in patients with myeloid malignancies including AML, MDS and CMML \>=55 years.

Thermal ablation has been recommended by worldwide guidelines as first-line treatment for hepatocellular carcinoma (HCC), while evidence regarding its efficacy for primary intrahepatic cholangiocarcinoma (iCCA) is lacking. The goal of this observational study is to study the efficacy of ablation in treating iCCA by comparing its prognosis with surgery. The main questions it aims to answer are: * Whether microwave ablation could achieve similar efficacy with liver resection in treating iCCA * What is the risk factor for ablation or surgery in treating iCCA * What kind of iCCA patients could receive ablation as their first-line treatment In this real-world multicenter cohort study, we will collect data of iCCA patients from hospitals who underwent microwave ablation (MWA) or liver resection (LR) for tumors within Milan criteria. Survival will be compared between patients treated by MWA or LR.
