Long-term Follow-up of Subjects Treated With CAR T Cells

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 (DF/HCC# 22-175) and NCT06026319 (DF/HCC# 23-474).

Efficacy of Dose-Adjusted Regimen on Survival in Frail Adults With Acute Lymphoblastic Leukemia

Acute lymphoblastic leukemia (ALL) is characterized by the abnormal proliferation of immature precursor cells, disrupting normal hematopoiesis and causing severe anemia and thrombocytopenia due to genetic mutations. Conventional treatment with intensive chemotherapy is limited for elderly patients or those with comorbidities, adversely affecting their survival. In Mexico, alongside a higher incidence, treatment-related complications are more frequent, particularly with drugs such as asparaginase or anthracyclines, which limits therapeutic efficacy. The transition to infusion-based therapies promises to reduce these complications, improve treatment tolerance, and optimize clinical outcomes, marking a significant advancement in the management of this disease. Modifying treatment regimens toward infusion therapies has the potential to significantly reduce adverse complications, enhance treatment tolerance, and ultimately improve clinical outcomes for patients who cannot benefit from conventional intensive regimens. This approach not only aims to optimize treatment effectiveness but also to minimize associated risks, thus representing an important advancement in the management of acute lymphoblastic leukemia in clinical settings such as those in Mexico

Intraoperative Blood Pressure Management and Dexamethasone in Lung Cancer Surgery

Surgery is the front-line therapy for non-small cell lung cancer (NSCLC) but postoperative complications remains high and patients' long-term outcome is still challenging. In addition to surgery, anesthetic management particularly intraoperative blood pressure management and use of dexamethasone may affect patients' early and long-term outcomes after surgery for NSCLC. This study aims to investigate the impact of intraoperative blood pressure management and dexamethasone administration on early and long-term outcomes in patients undergoing surgery for lung cancer.

Perioperative Epidural Block and Dexamethasone in Pancreatic Cancer Surgery

Pancreatic cancer remains a devastating disease with an average 5-year survival rate of about 3-5%. Previous retrospective studies showed that perioperative epidural block and/or dexamethasone are associated with improved outcome after cancer surgery. This randomized trial aims to investigate the effect of perioperative epidural block and/or dexamethasone on long-term survival in patients following pancreatic cancer surgery.

Dexmedetomidine and Outcomes of Elderly Admitted to ICU After Surgery

Sleep disorder and delirium are common problems in intensive care unit (ICU) patients, and may lead to poor prognosis. The investigators' previous study showed that nighttime infusion of low-dose dexmedetomidine improved the sleep quality and decreased the incidence of delirium in ICU patients after surgery. Long-term follow-up of these patients showed that low-dose dexmedetomidine also improved 2-year survival and the quality of life in 3-year survivors. The purpose of this study is to investigate the effect of low-dose dexmedetomidine on the long-term outcome of elderly patients admitted to the ICU after noncardiac surgery.

Multi-Center Study Protocol: Impact of Sarcopenia in Early-Onset Colorectal Cancer.

Sarcopenia's role in early-onset colorectal cancer (EOCRC), a subtype increasingly diagnosed in individuals under 50 years, has not yet been investigated according to recent literature. Understanding the prevalence and prognostic impact of sarcopenia in EOCRC could inform tailored therapeutic approaches and improve patient outcomes.

Mesenteric Lymph Node Metastasis and Nutritional Status After Bowel Resection for Ovarian Cancer

Ovarian cancer is one of the three major malignant tumors in gynecology, causing more than 200,000 deaths globally each year, with the highest mortality rate. However, due to its insidious onset and lack of specificity in clinical manifestations, nearly 70% of patients are in advanced stages upon diagnosis. Ovarian cancer often spreads along the peritoneal surface of the abdominal and pelvic cavity and involves the intestines through direct extension or plasma membrane infiltration, resulting in impaired intestinal function and intestinal obstruction. Cytoreductive Surgery is a critical treatment for patients with ovarian cancer. Literature reports that about 60%-70% of patients with advanced ovarian cancer underwent bowel resection at the time of primary debulking surgery, with the main site of resection being the recto-sigmoid (48%-55%), followed by the rest of the colon (18%-20%) and the small bowel (6%-27%). Patients with bowel resection for ovarian cancer often have involvement of mesenteric lymph nodes (MLN), and the positive rate of MLN fluctuates from 37% - 79.4%, and the incidence of liver metastasis within 3 years in ovarian cancer patients with MLN involvement is 61.1%. However, ovarian cancer patients with bowel or liver involvement are susceptible to postoperative malnutrition due to their extensive surgery, as well as increased incidence of postoperative complications. Therefore, this study included patients who underwent bowel resection for ovarian cancer, and assessed the patients' MLN metastasis and nutritional status based on the relevant clinical indicators, in order to reduce the incidence of postoperative complications in patients with bowel resection, to improve the patients' prognosis, and to enhance the quality of life.

Microwave Ablation Versus Liver Resection for Intrahepatic Cholangiocarcinoma

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.

Id and Rd Maintenance Regimens After Induction of Remission in Multiple Myeloma.

Newly Diagnosed Myeloma Patients, who achieved efficacy above VGPR (very good PR)after initial treatment were enrolled. Patients were then randomly assigned to Id and Rd groups for maintenance treatment. Therapeutic effectiveness will be reviewed monthly until intolerant side effect or disease progression appear . The follow-up period is approximately 2 years.

A Novel Target Delineation Scheme in High-grade Glioma Patients: a Randomized Single-blind Clinical Trial

The main question it aims to answer are: 1. whether the new target delineation scheme can improve Progression-free Survival 2. whether it can reduce the incidence of radiation complications in high-grade glioma patients. Participants in trial group will be performed radiotherapy of new target delineation method after the completion of the operation within 4-6 weeks., while participants in the control group be performed radiotherapy of EORTC(European organisation for research and treatment of cancer) target delineation method.Temozolomide 75 mg / ( m² · d ) will be given to both groups of patients during radiotherapy. After radiotherapy, its dose changes to 150 \~ 200 mg / ( m² · d ) for 5 days and stopped for 23 days as a cycle. There are 6 cycles in total.
