Filter by:Post-operative concomitant radiochemotherapy is a treatment that is difficult to achieve for several reasons. First of all, and by definition, these patients have had recent surgery, most often accompanied by several weeks of hospitalization and weight loss. In addition, the functional recovery of feeding capacity is not always complete at the time of the start of irradiation. In addition, concomitant radiochemotherapy is responsible for very frequent radiomucitus which alters the feeding capacity of patients during treatment. In total, the rate of complete radiochemotherapy (3 cures of cisplatin administered) varies from 50 to 70% depending on the studies, which were carried out in selected populations within the framework of an experimental clinical trial and without distinguishing between positive and negative Human Papilloma tumours . In our experience, in a population with a very high preponderance of non-Human Papilloma-related tumours and not selected by participation in an experimental trial, complete radiochemotherapy is only possible in about 40% to 50% of cases.However, the amount of cisplatin actually administered is correlated with overall survival. Therefore, it is logical to assume that increasing the number of patients receiving full treatment may result in increased survival. While the need for nutritional care during radiotherapy is clearly established, its modality remains debated. Recently, a randomised study of 159 patients treated by radiotherapy (or radiochemotherapy) showed that the simple systematic prescription of oral food supplements (500 kcal/d) in addition to the usual dietary advice was associated with a lesser reduction in weight at the end of radiotherapy (main objective) but also with an improvement in the tolerance of the treatments. Overall, nutritional management during treatment varies greatly, ranging from simple dietary monitoring to prophylactic gastrostomy and the insertion of a nasogastric tube on demand during treatment. This heterogeneity of management found in the literature is also observed at the regional level. This project will also make it possible to propose a harmonized support strategy at the inter-regional level.
Patients with unresectable or metastatic gastric or esophageal cancer, with first-line treatment applied are to be recruited in the study. In the current study, the efficacy and safety of anlotinib hydrochloride combined with nivolumab as second-line or salvage chemotherapy will be evaluated in Chinese patients with advanced gastric adenocarcinoma and esophageal squamous cell carcinoma. 48 patients could provide adequate precision rather than controlling type I&II error.
Neoadjuvant chemoradiotherapy treatment represents the standard approach for resectable locally advanced esophageal squamous cell carcinoma. The incidence of pulmonary infection and other perioperative complications were higher in patients who received esophagectomy and neoadjuvant chemoradiotherapy than those without neoadjuvant treatment and surgery patients. However, reliable clinical data can quantify the damage degree of immunologic function caused by chemotherapy and radiotherapy is still unknown. This project regards the level of lymphocyte and immunocyte in peripheral blood as a quantitative index to reflect the dynamic change of the immunologic function of patients with locally advanced esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy treatment. Meanwhile, the investigators will also investigate the relationship between the level of lymphocyte and immunocyte in peripheral blood and the response rate of neoadjuvant therapy.
This clinical trial aims to investigate the efficacy of Calcipotriol ointment combined with 5-fluorouracil cream as an immunotherapy for actinic keratosis in Organ Transplant Recipients (OTRs) before transplantation and determine whether it can prevent cutaneous squamous cell carcinoma (SCC) in OTRs post-transplant.
This is a multi-center, open-label, non-interventional, retrospective registry study, with no pre-set statistical assumptions and will not intervene subject's clinical treatment or clinical management. In the study, the clinical data of the subjects will be retrospectively collected from the electronic health records (EHR) of each research center. The clinical information will be based on the actual medical records of the cases. After the retrospective study time (June 30, 2020), patients will be followed for one-year and two-year survival. Clinical treatment and management will be based on local clinical practices and regulations. This study will record the actual diagnosis and treatment, and will not interfere with any clinical decision. After subject-out, patients will be followed for one-year and two-year survivals, thus the follow-up consent will be exempted. All patients receiving PD-1 monoclonal antibody in combination with chemotherapy will be visited during the entire study period. At the end of study, investigator will check up on the conditions of patients who withdraw from the study.
60% of hypopharyngeal cancers were locally advanced at the time of diagnosis. The standard treatment was surgery and postoperative radiotherapy. Compared with traditional surgery and postoperative radiotherapy, induction chemotherapy combined with radiotherapy has a better laryngeal retention rate without reducing the curative effect, and established an organ function preservation treatment strategy. Induction chemotherapy can reduce tumor burden and reduce distant metastases. At present, induction chemotherapy followed by concurrent chemoradiotherapy has become the standard treatment for the laryngeal preservation in locally advanced hypopharyngeal and laryngeal cancer. This study aimed to investigate the efficacy and safety of a PD-1 inhibitor toripalimab combined with chemotherapy as induction therapy in hypopharyngeal cancer.
Recessive dystrophic epidermolysis bullosa (RDEB) is a hereditary skin disease characterized by cutaneous and mucosa fragility. Blister formations and erosions, resulting in chronic wounds and dystrophic scars, lead development of aggressive cutaneous squamous cell carcinoma (cSCC) in young subjects. cSCC in RDEB patients are often recurrent and sometimes aggressive. Although fibrotic and inflammatory microenvironment plays an important role in the tumoral process, specific mechanisms in cSCC of RDEB patients are still unknown. Actually, the only treatment is a wide surgical excision with poor prognostic (80% of death after the first occurrence of cSCC). The objective of the study is to describe the molecular signatures in the cSCC in RDEB patients
A case-control study with oral squamous cell carcinoma (OSCC) patients from Instituto do Câncer do Estado de São Paulo (ICESP) and healthy volunteers. In this study, it will be collected saliva samples from both groups that will be submitted to sequencing analysis to evaluate the frequency of ALDH1b1 and ALDH2 polymorphisms in the Brazilian population. Also, correlate OSCC risk to alcohol consumption or smoke, by applied questionnaires.
The aim of this study is to investigate the efficacy and safety of anrotenib plus toripalimab in the treatment of advanced esophageal squamous cell carcinoma. In addition, the investigators will explore the possible mechanisms of anrotinib combined with toripalimab in advanced esophageal squamous cell carcinoma, and screen out biomarkers that can predict the efficacy of combination therapy.
The purpose of this study is to evaluate the safety and efficacy of SCT-I10A combined SCT200 or SCT-I10A combined SCT200 plus chemotherapy in advanced esophageal squamous cell carcinoma and colorectal cancer
