Filter by:This is a prospective, phase II, non-randomized clinical imaging trial. Ga68-FAPI-46 is a novel radiotracer used in PET/CT imaging, targeting a protein of the tumor microenvironment called FAP (Fibroblast activation protein). The aim of the study is to assess the accuracy of Ga68-FAPI-46 PET/CT for preoperative assessment of peritoneal carcinomatosis in colorectal and ovarian cancer.
Epidermoid Carcinoma of the Upper Aerodigestive Tract (CEVADS) is the 6th most common cancer worldwide. Despite current therapies (radiotherapy, surgery and chemotherapy), cancers of the Upper Aerodigestive Tract (UAT) have a poor prognosis, with a 10-year survival rate of no more than 20%. For recurrent or metastatic CEVADS, the therapeutic arsenal, based for many years on chemotherapy and anti-EGFR (Epidermal Growth Factor Receptor) agents, has been enriched by a new therapeutic class: PD-1 inhibitors. For CEVADS, PD-1 inhibitors have been approved for second-line treatment of nivolumab for over a year, and are now used in first-line treatment of pembrolizumab. The results of this therapeutic class in CEVADS are not as spectacular as for melanoma or bronchial cancer. Indeed, only 20% of patients have a favorable response, compared with half who experience disease progression. This low proportion of responders can be explained by tumor heterogeneity within CEVADS and poor patient selection. The only marker used to select patients is PD-L1 expression detected by ImmunoHistochemistry (IHC). However, it seems that this marker, described as imperfect, is still little explored in ENT. It needs to be compared with the expression of other cell lines in the tumor microenvironment, which could play an important role in resistance to PD-1 inhibitors. IHC identifies all macrophages using the CD68 marker, while the CD163 marker is specific to M2 macrophages. Other targets in the microenvironment are also being investigated, with the discovery of a Tertiary Lymphocyte Structure (TLS) in melanoma treated with immunotherapy. It therefore seems necessary to gain a better understanding of the mechanisms of tumor progression under immunotherapy in order to develop strategies to optimize response to treatment. This would enable better selection of patients likely to benefit from immunotherapy, and open up prospects for therapeutic combinations. The hypothesis is that macrophages, but also other cells and factors in the CEVADS microenvironment, play a decisive role in resistance to PD-1 inhibitors. The aim is therefore to continue these macrophage analyses, extend them to other cells in the microenvironment and link them to other prognostic factors under investigation. A prospective study will analyze tumor tissue during treatment with PD-1 inhibitors, in order to correlate all the factors studied with response or resistance to immunotherapies. In addition, the oral microbiota, in the lineage of the intestinal microbiota, has been shown to be highly stable over time and to play a role in the oncogenesis of certain cancers, notably CEVADS. Like the intestinal microbiota, it could also represent a prognostic factor in the response to immunotherapies. Of all the bacteria in this oral microbiota, one has been shown to play a major role: Fusobacterium nucleatum (F. nucleatum). However, little is known about the mechanism of action of intratumoral F. nucleatum on the development of CEVADS. In particular, it is thought to play a role in local cancer immunity, via macrophages, regulatory T cells (Tregs) and TLRs. Finally, it appears that specific antimicrobial T-cell responses may cross-react with tumor antigens, hence the importance of also analyzing the metabolome of commensal bacteria.The aim of this study was to evaluate the evolution of the presence of this bacterium in saliva, as well as the specific immune response to F. nucleatum in patients with CEVADS during immunotherapy treatment.
The purpose of this clinical research study is to investigate the efficacy and safety of Radiotherapy Combined with TKI and Anti-PD-1 Antibody for Stage IIIA Hepatocellular Carcinoma with Portal Vein Tumor Thrombus(PVTT).
This study intends to evaluate the efficacy and safety of blank- microsphere transcatheter arterial embolization-hepatic arterial infusion chemotherapy of oxaliplatin, 5-fluorouracil and leucovorin (bTAE-HAIC) plus Lenvatinib and Camrelizumab for patients with intermediate-advanced huge hepatocellular carcinoma.
This is a single-center, prospective, single-arm, phase II clinical study, with the purpose to evaluate the therapeutic efficacy and safety of envafolimab combined with chemoradiotherapy and recombinant human endostatin in patients with locally advanced nasopharyngeal carcinoma.
This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint Ultrahigh (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, doxorubicin, and cyclophosphamide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. There is some evidence from previous clinical trials that people who have a MammaPrint Ultrahigh Risk result may be more likely to respond to chemotherapy and immunotherapy. Adding durvalumab to usual chemotherapy may be able to prevent the cancer from returning for patients with MP2 stage II-III hormone receptor positive, HER2 negative breast cancer.
This phase II trial tests how well INCMGA00012 (retifanlimab), INCAGN02385 (tuparstobart), and INCAGN02390 (verzistobart) works in treating patients with Merkle cell carcinoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or has spread from where it first started (primary site) to other places in the body (metastatic) and has not responded to previous PD-(L)1 treatment (refractory). A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as PD-1, LAG-3, and TIM-3 molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as retifanlimab, tuparstobart, verzistobart may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
The purpose of this study is to analyze esophageal cancer patients who underwent neoadjuvant immunotherapy with chemotherapy followed by esophagectomy to determine whether additional adjuvant therapy is associated with improved survival outcomes.
This is an exploratory qualitative study among People Living With HIV (PLWH) of diverse racial/ethnic and sexual and gender minority (SGM) identities to explore individual, interpersonal, and structural oral health equity factors that serve as barriers or facilitators of accessing oral health care, knowledge and perceptions of human papillomavirus (HPV) vaccination and Oral squamous cell carcinoma (OSCC) /Oropharyngeal squamous cell carcinoma (OPSCC), and to collect recommendations on how to increase access to oral health care and engage PLWH in OSCC/OPSCC prevention.
