Filter by:This is a prospective multicenter randomized controlled trial study. According to the enrollment criteria, patients with locally advanced rectal cancer who need neoadjuvant therapy before radical surgery were randomly divided into the organoids drug sensitivity group and the standard whole-course neoadjuvant therapy group. The Organoids drug sensitivity group was treated with personalized neoadjuvant therapy under the guidance of tumor organoids drug sensitivity technology combined with standard long-term radiotherapy. The standard whole-course neoadjuvant therapy group was treated with neoadjuvant simultaneous radiotherapy and chemotherapy (Total Neoadjuvant Therapy, TNT) based on guidelines and clinical experience. The tumor pathological complete remission rate (pCR), postoperative complication rate, postoperative tumor withdrawal grade, postoperative recurrence rate, treatment tolerance rate, R0 resection rate, and sphincter preservation rate were observed and compared.
The purpose of this Phase II, Multicenter, Randomized Controlled Clinical Trial is to evaluate the efficacy and safety of PD-1 inhibitor Plus GP chemotherapy as Neoadjuvant Therapy in the Treatment of Locoregionally Advanced Nasopharyngeal Carcinoma.
False negative rate (FNR) in patients who has accepted neoadjuvant therapy is high. Blue dye and radioisotope as dual-tracer can decrease FNR. Several large clinical trials showed that using dual trace with blue dye and radioisotope can reduce the FNR to less than 10%. But radioisotope is still not approved in China and can cause radiocontamination. A novel dual-tracer which can decrease the FNR in patients after neoadjuvant therapy is urged to be explored. Contrast enhanced ultrasonography (CEUS) can make the lymphatic drainage path and sentinel lymph nodes visible. Retrospective studies found that CEUS can locate SLN precisely. So this clinical trial aim to evaluate FNR, detective rate and numbers of SLN by using CEUS combined with blue dye as dual-tracer in sentinel lymph node biopsy in breast cancer patients after neoadjuvant therapy and the accuracy of CEUS for the diagnosis of lymph node metastasis before and after neoadjuvant therapy.
To determine the safety and efficacy of Sindilimab combined with Paclitaxel and Cisplatin in neoadjuvant chemotherapy for Locally Advanced Cervical Cancer
This Phase II study was designed to evaluate the safety and efficacy of Atezolizumab in combination with Chemotherapy compared with treatment with Chemotherapy alone in previously untreated Limited-Stage Small Cell Lung Cancer patients.
Liver resection is the only curative treatment for patients with colorectal liver metastases (CRLM). Most patients undergo chemotherapy (CT) before liver surgery. CT objectively decreases patient functional capacity. It has already been demonstrated that a structured training program carried out during the 4 weeks following CT, while the patient is waiting for liver resection, is able to return the functional capacity to baseline levels. Despite this, multimodal prehabilitation programs (MPP) during preoperative CT have not been evaluated or implemented. The aim of this study is to investigate whether a 16-week MPP applied during and following CT in CRLM patients will result in a significant increase in physical fitness when compared to those that undergo MPP only during the 4-weeks, between the end of CT and liver resection.
Neoadjuvant chemoradiotherapy treatment represents the standard approach for resectable locally advanced esophageal squamous cell carcinoma. The incidence of pulmonary infection and other perioperative complications were higher in patients who received esophagectomy and neoadjuvant chemoradiotherapy than those without neoadjuvant treatment and surgery patients. However, reliable clinical data can quantify the damage degree of immunologic function caused by chemotherapy and radiotherapy is still unknown. This project regards the level of lymphocyte and immunocyte in peripheral blood as a quantitative index to reflect the dynamic change of the immunologic function of patients with locally advanced esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy treatment. Meanwhile, the investigators will also investigate the relationship between the level of lymphocyte and immunocyte in peripheral blood and the response rate of neoadjuvant therapy.
This is a single-arm phase II clinical trial to evaluate the initial efficacy and safety of toripalimab combined with axitinib as neoadjuvant therapy for advanced/metastatic non-clear cell renal cell carcinoma
Pancreatic cancer is the most lethal malignancy of human being. Surgery is the only potential cure of pancreatic cancer. The invasion of major abdominal arteries is one of the most important factor restricting surgical intervention. For artery-involved pancreatic cancer (ai-PC) patients, pre-operative adjuvant therapies, especially the neoadjuvant chemotherapy, has brought exciting postoperative survival. Yet due to the potential screening effect of this treatment strategy, nearly half of ai-PC patients failed to benefit from surgery because of disease progression, adverse reactions of adjuvant treatment and other reasons. Artery divestment for the treatment of ai-PC firstly reported by our center, can significantly increase resection rate and produce overall survival benefit in some patients. This study is to explore whether up-front surgery with artery divestment combined curative pancreatectomy or the chemotherapy-first strategy would be more beneficial for ai-PC patients' survival. Subjects will be randomized to treatment group either receiving up-front artery divestment combined pancreatectomy (Surgery Group) or adjuvant chemotherapies (Chemo Group). In Surgery Group, an artery divestment combined pancreatectomy will be performed if no pre-operative contra-indication or intra-operative metastasis were revealed. Post-operative adjuvant chemotherapies were prescribed according to performance status. In Chemo Group, adjuvant chemotherapy of gemcitabine or gemcitabine + cisplatin will be utilized according to performance status. After 2 circles of adjuvant chemotherapies, patients will be reevaluated and curative operation would be attempted if without disease progression. Overall mortality at one year after randomization will be the primary endpoint. Other parameters as overall survival after 2 and 3 years, median survival, disease-free survival, margin status of subjects receiving curative surgery, etc. will also be observed.
Apatinib has been proved to be effective and safe among patients in advanced colorectal cancer in several trials. the investigators aimed to evaluate its efficacy and safety as the neoadjuvant therapy in real world practice, and to explore factors associated with efficacy.
