Surgery is usually the first choice for early-stage oral squamous cell carcinoma (OSCC). However, there is currently a lack of consensus on whether patients with clinically negative cervical lymph nodes (N0) should undergo elective neck dissection (END) at the same time. About 20-30% of cT1-2N0M0 oral cancer patients have occult lymph node metastasis, and existing examination methods cannot accurately predict occult cervical lymph node metastasis. Therefore, most clinical retrospective and prospective studies recommend END for cN0 patients. Previous studies have found that no cancer cells were found in the cervical lymph nodes of 70% of patients after END. This unselective END can cause patients with accessory nerve dysfunction, neck scars, etc., and prolong hospitalization and surgery time. Exploring the treatment model for patients with early-stage oral squamous cell carcinoma is an urgent problem that needs to be solved. This study intends to conduct a study on the neoadjuvant treatment of tislelizumab, carboplatin, and albumin-bound paclitaxel. After neoadjuvant immunotherapy in patients with early-stage oral cancer (T1-2N0M0), the primary tumor is treated with standard surgical treatment. Comparison with A single-center exploratory clinical study of traditional oral cancer radical resection + selective neck lymphadenectomy was conducted to explore its effectiveness through the difference in 2-year disease-free survival (DFS). This research plan covers 40 patients with early-stage oral squamous cell carcinoma. They will be randomly divided into tislelizumab, chemotherapy combined with surgery (experimental group) and traditional surgery (control group) in a 1:1 ratio. The patients' tumors will be collected. Tissues, adjacent cancer tissues, whole blood samples, saliva samples, and matrix samples were used to observe the changes in imaging and pathology compared with treatment. At the same time, the clinical information of the patients was collected, such as quality of life indicators such as judgment function, pathological grading, staging, treatment, Spine, serology, imaging, etc., mainly to evaluate the 2-year event-free survival (EFS) between the experimental group and Weather Forecast, and the 3-year overall survival (OS) and patient quality of life between the experimental group and Weather Forecast.
In patients with locally advanced head and neck squamous cell carcinoma undergoing standard surgical treatment after neoadjuvant immunochemotherapy, can PD-1 inhibitor therapy be used instead of adjuvant radiotherapy for both primary and lymph node pathology? To provide further evidence-based medical evidence for the late precision treatment of HNSCC patients after neoadjuvant immunochemotherapy. Avoid the side effects caused by excessive radiotherapy, especially avoid the occurrence of second primary cancer, radiation osteonecrosis and other diseases. 1. Main study endpoint: A randomized controlled, non-inferiority, multicentre Phase III trial was conducted to investigate the difference in 5-year overall survival (OS) between experimental group (Group B) and control group (group A) in patients undergoing standard surgical treatment after neoadjuvant immunochemotherapy for locally advanced HNSCC, with both primary and lymph node pathology revealed by pCR. At the same time, adverse events and safety were evaluated according to NCI-CTCAE 5.0 criteria and RTOG later radiotherapy damage evaluation criteria. Safety indicators focused on late radiotherapy toxicity and the incidence of grade 3 and 4 adverse reactions in NCI-CTC AE 5.0 and RTOG. The differences in the incidence of grade 3 and 4 adverse events were compared between the experimental group and the control group. 2. Secondary study endpoint: The differences in 2-year disease-free survival (DFS), regional relapse-free survival (RRFS), distant metastasis free survival (DMFS), safety and adverse events were compared. Safety evaluation NCI-CTC AE 5.0 standard was used to evaluate the acute safety index of radiotherapy, and RTOG late-stage damage evaluation standard was used to evaluate the late-stage safety index of radiotherapy. 4) Exploratory goals The influence of prognostic laboratory indicators, clinical risk factors were analyzed. To explore the factors that influence the efficacy of radiotherapy after pCR immunotherapy.
In this study, 200 patients with resectable head and neck squamous cell carcinoma (T3 or T4, N0) were enrolled and preoperatively combined with pembrolizumab (PD-1 inhibitor), carboplatin, and albumin-binding paclitaxel. The subjects were randomly divided 1:1 into four treatments and two treatments. The imaging and pathological changes of tumor and paracancer tissues before and after treatment were observed. Clinical information, such as pathological grade, stage, treatment, prognosis, serology, imaging, etc., was collected to evaluate the safety and efficacy of 4-course pembrolizumab combined with carboplatin and albumin-binding paclitaxel compared with 2-course neoadjuvant therapy for resectable oral and oropharyngeal squamous cell carcinoma. This is a prospective, one-arm, phase II clinical study. Main purpose By calculating pathological complete response (pCR) in the experimental group, we evaluated the efficacy (optimality) of four courses of pembrolizumab combined with carboplatin and albumin-binding paclitaxel compared with two courses of neoadjuvant therapy for resectable oral and oropharyngeal squamous cell carcinoma (T3 or T4, N0). At the same time, this study evaluated the safety of medication, specifically: The severity of adverse events associated with neoadjuvant therapy will be graded according to NCI CTCAE (version 5.0) during this study and during follow-up, and the occurrence of adverse events in the experimental and control groups will be compared. To evaluate the safety of 4-course Pembrolizumab combined with carboplatin and albumin-binding paclitaxel compared with 2-course neoadjuvant therapy for resectable oral and oropharyngeal squamous cell carcinoma (T3 or T4, N0). Secondary Purpose 1. The event-free survival (EFS) of the two groups were compared; 2. The main pathological response rate (MPR) of the two groups were compared; 3. pTR of the two groups was compared; 4. Overall survival (OS) of the two groups was compared; 5. The radiological responses of the two groups were compared; 6. The operation delay rate of the two groups was compared; Exploratory purpose For the response of enrolled patients after treatment, group treatment was conducted according to the guidelines, and stratified factors influencing the prognosis and treatment plan of immunotherapy were explored according to stratification. The stratification factors taken into consideration are: P16 status, smoking history, TNM stage, tumor reduction (MPR condition), presence of risk factors (according to the guidelines, risk factors are presence of episopercular invasion, positive incisal margin, proximal incisal margin, pT3 or pT4, pN2 or pN3 lymph nodes located in the IV and V regions of the neck, Nerve invasion, vascular invasion, etc.). The purpose of this study was to stratified risk factors for evaluating the efficacy of pembrolizumab combined with carboplatin and albumin-paclitaxel in neoadjuvant therapy for resectable head and neck squamous cell carcinoma. At the same time, hematological, pathological and fecal indicators collected in the design of the experiment were collected. Correlation analysis was conducted to statistically analyze the relationship between these indicators and the therapeutic effect of the program.
This is a prospective, open, single-center clinical study of RC48 combined with PD-1 and radiotherapy as bladder-preserving therapy in patients with muscular invasive bladder uroepithelial carcinoma with high HER-2 expression (IHC 2+ or 3+). The study was conducted in accordance with the Good Practice for Clinical Trials of Pharmaceutical Products (GCP). Six patients were enrolled in this study. Each patient received RC48 injection [2.0 mg/kg, Q2W, iv] and Toripalimab injection [3mg/kg, Q2W, iv] for 1~2 cycles, and radiotherapy at the second or third cycle. The total dose of bladder irradiation field was greater than 50Gy (about 30 times), and the safety monitoring of the subjects was conducted within 28 days after receiving the study drug treatment for the first time. Adverse events were graded using the National Cancer Institute (NCI) Standard for the Assessment of Common Terminology for Adverse Events (CTCAE) Version 5.0 guidelines, and the occurrence of DLT in patients was observed. If the subject does not complete the safety assessment for the tolerance observation period for non-dose tolerance reasons, a new subject will be replaced.
G/GEJ adenocarcinoma is one of the most common malignant tumors in China, ranking the fifth highest incidence and third highest mortality worldwide. Currently, surgical resection is the preferred treatment for G/GEJ adenocarcinoma, while the 5-year survival rate of patients is lower than 25%. Compared with surgical resection, immunotherapy is proved to be able to effectively prolong the survival time of patients. On one hand, with the continuous promotion of immunotherapy drugs, the exploration of neoadjuvant application of immunotherapy in G/GEJ adenocarcinoma has become a hotspot in recent years. It's also on their way that clinical trials of programmed death receptor-1 (PD-1), programmed death ligand-1 (PD-L1) and other immune checkpoints are carried out. On the other hand, the research found that although the curative effect of immune therapy seems better, the present G/GEJ adenocarcinoma immunotherapy marker researches mainly focused on the late stage of the cancer, with few studies of immune markers of neoadjuvant therapy for G/GEJ adenocarcinoma. Additionally, it's not quite feasible for single biomarkers to predict the immune treatment effect precisely. Therefore, combined with clinicopathology and therapeutic effects, this study is aimed to construct the efficacy prediction model of anti-PD-1 antibody together with chemotherapy for G/GEJ adenocarcinoma, by detecting RNA expression. Furthermore, this study will perform drug sensitivity test and bio-molecular test on patient derived organoid model to validate the biomarkers found from biological specimens.
In recent years, immunotherapy has become one of the important treatments for malignant tumors. Among them, PD-1 inhibitors have been widely used in clinical practice, and have shown a significant survival benefits in many patients. However, the incidence of immune-related adverse reactions (irAEs) of PD-1 inhibitors is relatively high, and severe cases can even threaten patients's life. At present, irAEs have become a bottleneck and it is urgent to establish a prevention strategy for the prediction of irAEs. In this study, we intends to use Sintilimab as the research drug. A prospective cohort study was carried out. Part of the sample which was used as a training set would be detected for producing a time-series multi-dimensional data such as differential genes, metabolites and immune factors. Then gene expression programming (GEP) was used to explore the irAEs recognition model. Then, based on this recognition model, internal verification ( part of samples from the center 1 ) and external verification ( part of samples from the center 2 and center 3 samples) are carried out to accurately predict the high-risk population of irAEs and realize the early-stage warning of Sintilimab induced- irAEs.
Through multicenter, open-label, randomised clinical trials, we intend to demonstrate that PD-1 treatment added to salvage surgery could further decrease the rate of disease progression and improve the survival outcome of patients with resectable locally recurrent nasopharyngeal carcinoma compared with those treated with salvage surgery alone.
The purpose of this research study is to see if the amount of vitamin D in ones blood makes it more or less likely to develop thyroid gland toxicity when being treated with immunotherapy that blocks the activity of proteins called programed death-1(PD-1) or programmed death ligand-1 (PD-L1). Immunotherapy is treatment that makes changes to the immune system to try to fight cancer. Immunotherapy treatments that block the activity of important parts of the immune system called PD-1 and PD-L1 are used to standardly treat many different types of cancer and can cause thyroid toxicity in certain people. In this study the treatment for your cancer is not research treatment but standard of care determined by your oncologist. Blood will be drawn before starting treatment to determine the amount of Vitamin D and also to assess thyroid function. Also questionnaires will be completed before starting treatment and while on treatment to assess symptoms you are experiencing.
Little is known about the characteristics of genetic mutation in a large multi-gene panel in epithelial ovarian cancer. This study is to explore the targeted genetic mutations via a multi-gene panel, which consists of more than 500 hundred genes. The mutation characteristics are to be revealed in single nucleotide variants, copy number variations, insertion-deletion variations, and genomic structural variations. The total mutation burden (TMB) will be calculated. The status of microsatellite instability, expression of PD-1 and PD-L1 antibodies are also tested. These findings will be studies in association with the patients' prognosis and sensitivity to platinum-based chemotherapy.
