Active clinical trials for "Carcinoma"

The purpose of this study was to evaluate its rationality in real-world data and provide clinical evidence for the refinement of nodal CTV delineation in nasopharyngeal carcinoma(NPC).

Merkel cell carcinoma (MCC) is a rare aggressive skin carcinoma. Approximately 80% of MCC are related to the Merkel Cell Polyomavirus (MCPyV). Although rates of relapse are high, the follow-up strategy lacks consensus. Patients are usually assessed clinically every 3 to 6 months for the first 2-3 years, and every 6 to 12 months thereafter. In the European guidelines, patients with early stages are monitored with clinical examination and ultrasonography of lymph nodes, while whole-body imaging is optional in patients with stage III disease, on a yearly basis for 5 years. Such strategy may prevent the diagnosis of infra-clinical recurrences, whereas patients could still be treated with surgery or radiation therapy. Until 2017, patients with advanced disease were treated with chemotherapies, with no long-term benefit. Immunotherapies with PD-1/PD-L1 inhibitors currently allow durable responses in 50% of such patients. This major change in the management of MCC patients argues for a follow-up strategy that would allow early diagnosis of infra-clinical metastases, when tumoral burden is still low. Given that all patients cannot be monitored by systematic regular imaging, additional non-invasive tools are needed. Blood-based biomarkers as a surrogate of tumor burden are advantageous as they can be repeated over time, providing guidance on when imaging is necessary. The study aims to assess two blood biomarkers, MCPyV T-Ag antibodies and cell-free miR-375, in a prospective fashion from baseline diagnosis, in a cohort of 150 European MCC patients

Patients were aged >18 years with histological confirmed GC/EGJC and were refractory to the first line of therapy. Additional eligibility requirements included: ≥1 measurable disease at baseline per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v 1.1); Eastern Cooperative Oncology Group Performance status of 0 or 1; or life expectancy of ≥ 3 months and adequate organ function. The main exclusion criteria were interstitial lung disease, pulmonary fibrosis, active or prior autoimmune disease or active hepatitis, or history of anlotinib or any other PD-L1/PD-1 antagonist treatment. Patients with abdominal fistula, diverticulitis, gastrointestinal ulcerative disease or perforation, or abdominal abscess within the prior 4 weeks were also excluded. This study was an open, exploratory single-arm, phase II trial. Enrolled patients received anlotinib (12mg, po. qd, d1-14) combined with toripalimab (240 mg, inv, over 30 min once every 2 weeks).

Evaluation of the efficacy and safety of the combination ATEZOLIZUMAB - BEVACIZUMAB in the treatment of locally advanced inoperable or metastatic hepatocellular carcinoma in Finistère

Primary treatment in nasopharynx cancers is radiotherapy (RT) or chemoradiotherapy (CRT) depending on the stage of the tumor. According to the guidelines, the dose of radiotherapy for primary tumors varies between 66-70 Gy. In consideration of modern radiotherapy techniques like IMRT with systemic chemotherapy for nasopharyngeal cancer, loco-regional control has been perfect. However, the rate of late complications from treatment, many of which are irreversible, is still high. Radiation-related optic neuropathy is the late complication that optic nerves might be affected during the radiotherapy due to the close location of the nasopharynx. Incidence of this is 8.7-9% in head and neck cancer and is observed between 2-9 years after RT. Painless, irreversible, and progressive vision loss usually occurs, and the pallor of optic disc margins, retinal vein dilatation, bleeding, and neovascularization are in the ophthalmic examination. The risk of optic neuropathy increases when the tumor is in close contact with optic nerves, radiation dose, concurrent chemotherapy used, history of diabetes or hypertension. The aim of our study is to prospectively evaluate optic neuropathy in nasopharynx cancer patients treated in our clinic.

This is a multicenter, prospective, observational study in which subjects will be treated with lenvatinib combined with TACE in un-resectable HCC patients who had not received systematic treatment or TACE treatment in the past.

Immunotherapy has become an essential therapeutic weapon against many cancers. Control point inhibitors (CPI, PD-1/PD-L1) have shown efficacy in the therapeutic management of tumors in the bladder in progression after administering platinum derivatives. But only 20% of patients get any clinical benefit from these heavy treatments in the long term. Treating metastatic patients without distinction means taking a considerable risk of toxicity and generates major costs. It is therefore urgent and important to exceed the current criteria for using immunotherapy. Recent studies have shown the interest of studying intestinal microbiota as a marker of the efficacy of immunotherapy. The investigators hypothesized that the proteomic signature of the intestinal microbiota in patients with locally advanced or metastatic urothelial carcinomas who responded to immunotherapies was special, and has very different characteristics from that of patients with the same pathology who do not respond to immunotherapy.

The investigators intend to perform a prospective, multicenter study to establish a set of clinical criteria for surgical stages of liver cirrhosis, which can be implemented to guide the surgical treatment of hepatocellular carcinoma (HCC).

In this study, the investigators aim at: Evaluate the presence of vasculogenic mimicry in urothelial carcinomas by CD31-PAS double staining. Correlate the presence of vasculogenic mimicry with the clinicopathologic features as age, sex, TNM stage, pathological grade, recurrence, carcinoma in situ, lymphovascular emboli, lymph node metastasis, necrosis, surgical margin, multifocality and tumor size in urothelial carcinoma.

Known risk factors inducing squamous cell carcinomas of the head and neck are tabacco and alcohol intake. However, the incidence of human papillomavirus (HPV) related oropharyngeal carcinomas is increasing. It is known that HPV+ and HPV- tumors have a different reaction to (chemo)radiotherapy. The exact mechanisms underlying these differences is not yet known but might be caused by changes in vascularity. Therefore the vasculature is imaged with the help of a study specific Gallium-68-DOTA-(RGD)2 PET/CT scan and a CT perfusion scan.
