Filter by:Esophageal cancer accounts for more than half of the world, seriously affecting people's health in China. 95% patients are squamous cell carcinoma. Surgery is the preferred treatment for early and middle stage esophageal cancer, but patients with clinical stage T4b or other surgical contraindications have no surgical opportunity. In recent years, radical chemoradiotherapy has played a key role in the treatment of local advanced esophageal cancer with some poor predicting biomarkers. Oral bacteria may play a pathogenic role in cancer and other chronic diseases by producing chemical carcinogens and inflammatory factors through direct metabolism. A large number of studies have also suggested that tooth loss and poor oral hygiene are closely related to upper digestive tract cancer, indicating the possible role of oral microorganisms in the occurrence and development of upper digestive tract cancer, and saliva is the main source of oral flora colonization. Therefore, it is worth further research to explore the interaction between microbial metabolism imbalance and radiotherapy in patients with esophageal cancer. In summary, we intend to conduct a prospective cohort study to explore the role of salivary microbes in radiotherapy in patients with initially inoperable patients with local advanced esophageal cancer.
It has been reported that patients with esophageal squamous cell carcinoma who achieved pathological complete response (PCR) to neoadjuvant chemoradiotherapy have better survival than those with non-PCR. Howeve, there is still recurrent diseases developed in PCR patients after esophagectomy. Herein, we aimed to investgate the risk factors of recurrence in PCR patients.
This is a nonrandomized, uncontrolled, open-label, multicenter Phase 2 study to evaluate the efficacy, safety, and tolerability of futibatinib in combination with PD-1 antibody-based SoC therapy in adult patients with solid tumors.
Randomized comparative trial of a 30% solution of ascorbic acid in 95% dimethylsulfoxide applied topically twice a day for 8 weeks vs 5% imiquimod cream in the treatment of biopsy proven squamous cell carcinomas of the skin in otherwise healthy adult patients. Outcome measure was biopsy proven resolution of the carcinoma.
In this case-only study, the investigators try to define a novel staging parameter, the Primary Tumor Burden Score (PTBS).
The purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).
Background: Recurrent respiratory papillomatosis (RRP) is a rare disease that causes wart-like growths in the airways. These growths come back when removed; some people may need 2 or more surgeries per year to keep their airways clear. Better treatments are needed. Objective: To see if a drug called bevacizumab can reduce the number of surgeries needed in people with RRP. Eligibility: People aged 18 and older with recurrent RRP; they must need surgery to remove the growths in their airways. Design: Participants will be screened. Their ability to breathe and speak will be evaluated. They will have an endoscopy: a flexible tube with a light and camera will be inserted into their nose and throat. They will have a test of their heart function and imaging scans of their chest. Participants will have surgery to remove the growths in their airways. Bevacizumab is given through a small tube placed in a vein in the arm. After the surgery, participants will receive 11 doses of this drug: every 3 weeks for 3 doses, and then every 6 weeks for 8 more doses. They will come to the clinic for each dose; each visit will be about 8 hours. Tissue samples of the growths will be collected after the second treatment; this will be done under general anesthesia. Participants may undergo apheresis: Blood will be drawn from a needle in an arm. The blood will pass through a machine that separates out the cells needed for the study. The remaining blood will be returned to the body through a second needle. Follow-up will continue for 1 year after the last treatment.
This is a multi-center, open-label, dose-escalation and cohort-expansion phase I clinical study to evaluate the safety and tolerability, pharmacokinetics profile, efficacy and immunogenicity of IMM2520 in subjects with advanced solid tumors.
Rationale: Vulvar squamous cell carcinoma (VSCC) is a rare cancer with a rising incidence. Standard treatment comprises wide local excision of the primary tumour and inguinal lymph nodes and sometimes (chemo) radiotherapy. Treatment is associated with impressive and long-lasting morbidity, sexual and psychological dysfunction and wound healing disorders. Recurrent disease develops in up to 40% of all treated patients. The unmet need, therefore, is a less radical and more effective treatment for VSCC. Hypothesis: Based on the local immune profile in a large fraction of patients with primary VSCC the investigators hypothesize that neoadjuvant PD-1 checkpoint inhibition may reinvigorate tumor-specific T cells resulting in a reduced tumor load, potentially leading to less radical surgery and reduces the recurrence rate. The primary objectives of this trial are to study clinical efficacy and immune activation of neoadjuvant PD-1 blockade in VSCC. Study design: This is a prospective, multicenter phase II non-controlled clinical trial in 40 VSCC patients. Study population: Clinically diagnosed FIGO I-III primary VSCC patients to be treated with surgery with curative intent. Intervention (if applicable): Anti-PD1 antibody pembrolizumab, 200 mg IV Q3W for a total of 2 administrations per patient over a period of 6 weeks prior to surgery. Main study parameters/endpoints: The primary endpoints are: - Clinical efficacy of neoadjuvant PD-1 blockade in VSCC, measured by objective change in tumour size (according to RECIST1.1) - The activation, proliferation and migration of the CD4+CD39+PD-1+ intratumoral T-cell population.
This is an investigator-initiated, single-arm, exploratory clinical study.The study population consisted of non-operative Locally Advanced Esophageal Cancer . The purpose of this study was to evaluate the efficacy and safety of Concurrent Chemoradiotherapy Following Immunotherapy Plus Chemotherapy for Patients With Locally-advanced Esophageal Squamous Cell Cancer.
