Filter by:This study is a single arm phase ll trial including 52 patients with T2N2-3M0#T3-4N0-3M0 (III-V) head and neck squamous cell carcinoma(HNSCC) eligible forresection, who receive Cetuximab+ Zimberelimab combined with cisplatin and Nab.paclitaxel.This proposed study will evaluate the efficacy and safety of preoperative administration of Cetuximab+ Zimberelimab combined with chemotherapy in Head and Neck Squamous Cell Carcinoma(HNSCC) who are about to undergo surgery.
The enrolled head and neck squamous cell carcinoma patients in this study received high-dose multiday chemotherapy with cisplatin and synchronous radiation therapy, which had a high risk of nausea and vomiting. On the first and third days, they took Netopitam Palonosetron capsules and dexamethasone to reduce the incidence of acute vomiting. The aim of this study is to evaluate the antiemetic effect of Netopitam Palonosetron capsules and to explore the effectiveness of using Netopitam Palonosetron capsules again for antiemetic treatment during the study period when breakthrough vomiting occurs.
Patients with locally advanced (stage III to stage IVB) poorly differentiated head and neck squamous cell carcinoma (excluding nasopharyngeal carcinoma) who meet the inclusion criteria will have their blood samples collected, tumor tissue samples or patient paraffin tissue, and slides for comprehensive genomic sequencing and analysis. The study is divided into two groups. Arm1 group: Patients with stage IVB (T4bNxM0) poorly differentiated head and neck squamous cell carcinoma (excluding nasopharyngeal carcinoma) will receive PD-1 combined with platinum-based chemotherapy and albumin-bound paclitaxel (dose according to the drug instructions) for 2 to 3 cycles (determined by the researcher based on tumor shrinkage). If the imaging achieves complete response (CR) or partial response (PR), suitable patients will undergo surgical treatment. Patients who are not suitable for surgery or have stable disease (SD)/progressive disease (PD) will receive concurrent chemoradiotherapy or concurrent chemoradiotherapy combined with PD-1 treatment (up to a total of 17 cycles). Arm2 group: Patients with stage III and IVA (T3NxM0, T4aNxM0) poorly differentiated head and neck squamous cell carcinoma (excluding nasopharyngeal carcinoma) will receive PD-1 combined with platinum-based chemotherapy and albumin-bound paclitaxel (dose according to the drug instructions) for 2 cycles. Patients who undergo surgery within 2 weeks will receive PD-1 monotherapy maintenance treatment or low-dose radiotherapy followed by PD-1 monotherapy maintenance treatment based on pathological results. Patients who do not achieve pathological complete response (pCR) and have positive surgical margins or extracapsular extension will receive concurrent chemoradiotherapy followed by PD-1 maintenance treatment (up to a total of 17 cycles). Patients without high-risk factors will receive PD-1 maintenance treatment after radiotherapy (up to a total of 17 cycles). After completion of treatment, all patients will be followed up every 3 months for 1 year. Subsequently, patients will be followed up every 6 months for 3 years. Thereafter, patients will be followed up annually. Patient recurrence and survival data will be recorded.
Head and neck cancers represent more than 500,000 cases per year worldwide, and often involve post-treatment relapse. The oral cavity is the most frequent site, but early disease stages are still insufficiently characterised and poorly detected. The study's aim is to better understand the oral mucosa somatic evolution, and how it can give rise to oral squamous cell carcinoma (OSCC). This is a multi-centric, descriptive, non-interventional cohort in healthy adult subjects. The aim of the study is to detect the presence of OSCC driver gene mutations in healthy subjects' oral mucosa, quantify whether they provide cells with a selective advantage, and study the impact of tobacco and alcohol consumption on the mutational load. This study will not allow to identify potential malignant cells, and will be usable for diagnostic purposes.
The purpose of this phase 0 Window of Opportunity study is to have subjects with Head and Neck Squamous Cell Carcinoma (HNSCC) receive same dosage of Black Raspberry Extract between their cancer diagnosis and standard treatment (surgery). Tumor biopsies and research blood before and after the investigational treatment (Black Raspberry Extract lozenges) are collected for translational research. The investigational treatment is kept short to avoid delaying standard treatment.
This phase II trial compares the effect of usual radiation therapy with cisplatin/carboplatin (chemoradiation) to the addition of xevinapant with chemoradiation in patients with head and neck cancer. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Xevinapant is a first-in-class antagonist of inhibitor of apoptosis (programmed cell death) proteins (IAPs), which leads to tumor cell death and enhances tumor cell sensitivity to chemotherapy and radiotherapy. Giving xevinapant with chemoradiation may be more effective in preventing head and neck cancer from growing or spreading than chemoradiation alone.
This is a single-center, prospective, single-arm Phase II clinical study to evaluate the efficacy and safety of IBI110 in combination with Sintilimab in subjects with advanced or metastatic esophageal squamous cell carcinoma (ESCC) who have failed first-line treatment with PD-1 inhibitors combined with chemotherapy. Patients who meet the inclusion criteria will be treated with IBI110 combined with Sintilimab until disease progression, death, toxicity intolerance, withdrawal of informed consent, initiation of new anti-tumor therapy, or termination of therapy for other reasons specified in the protocol. RECIST v1.1 was used for clinical tumor imaging evaluation every 6 weeks during treatment.
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.
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.
