Filter by:Patients with recurrent or metastatic uterine cervical squamous carcinoma have very poor prognosis. For eligible patients, radiotherapy remains the choice, which has the most effective impact on the survival periods. On the hand, anti-angiogenic therapy has been proved to be promising treatment for recurrent or advanced cervical carcinomas. This study aims to discover the objective response of combination therapy with nimotuzumab (an anti-epidermal growth factor receptor [EGFR] IgG1 humanized monoclonal antibody) and radiotherapy in recurrent or metastatic uterine cervical squamous carcinoma in a single-arm, open, phase 2 clinical trial. The primary endpoint is the objective response rate evaluated by imaging methods. The second endpoints are the progression-free survival and overall survival. The treatment toxicity is regarded as one the second endpoint.
Postoperative adjuvant radiotherapy is a key component of comprehensive treatment of meningioma. However, for atypical meningioma after total resection, there is still a huge controversy in patients who need adjuvant radiotherapy after surgery. Many scholars have focused on this problem and carried out some small-scale retrospective studies, but they have contradictory results. Some of the studies found that postoperative adjuvant radiotherapy could not improve the prognosis of patients, but was questioned because the sample size was too small, resulting in insignificant results, while other studies found that postoperative adjuvant radiotherapy can improve progression free survival. A study based on the National Cancer Database found that postoperative adjuvant radiotherapy and gross tumor resection are associated with a good prognosis. A recent meta-analysis enrolled a total of 757 patients and found that postoperative adjuvant radiotherapy reduced the risk of tumor recurrence but did not improve survival time. Our team reviewed the meningioma data in the SEER database and conducted a study previously. The study found that postoperative adjuvant radiotherapy did not improve the overall survival of these patients. The relevant research results were recently published in Frontiers in oncology. We further reviewed and summarized the single-center data of our hospital and found that postoperative adjuvant radiotherapy could not improve the progression free survival and overall survival of patients. Besides, we also performed a meta-analysis and found that postoperative adjuvant radiotherapy had a trend to improve progression-free survival, but there was no statistical difference. Because there are many deficiencies in previous researches, and the research results are also contradictory, it is still unclear whether patients with atypical meningioma who have undergone gross total resection can benefit from postoperative adjuvant radiotherapy. Further high quality clinical trials is still needed to be conducted in order to guide the postoperative care of patients. Therefore, we intend to conduct this multicenter randomized controlled trial to determine the value of postoperative adjuvant radiotherapy in patients with atypical meningioma who underwent gross total resection.
This study aims to analyze the effects of long-acting versus short-acting granulocyte colony stimulating factor (G-CSF) on the prevention febrile neutropenia (FN) in epithelial ovarian cancer patients. Patients receive platinum-based chemotherapy of 3 to 4 weeks. Patients are randomized into study group and control group. In study group, patients accept long-acting G-CSF 48 hours from the chemotherapy. While the control group accept regular or prophylactic treatment of short-acting G-CSF according to National Comprehensive Cancer Network guidelines. The primary end is the incidence of FN in every course of chemotherapy. The secondary ends include: the incidences of myelosuppression, doses of G-CSF and its expenses, visits to outpatient and emergency clinics, adverse events related to G-CSF, quality of life, and survival outcomes (progression-free survival and overall survival).
The investigators design a large sample size study in the real-world to explore whether targeted therapy and immunotherapy can improve the survival, quality of life and drug safety of patients with advanced hepatobiliary tumors, and analyze the correlation between genetic variation and the effectiveness of therapy.
This study involves patients treated with cisplatin and etoposide (induction therapy), followed by treatment with a drug called S1 (maintenance therapy). The main purpose of this study is to determine if this type of treatment will delay the growth of the tumor and if so, for how long. The primary endpoint is progression free survival and second endpoints are toxicities, overall survival.
A open label 1:1 randomized phase II exploratory study investigating adjuvant therapy in patients with molecular biologically detectable residual disease after primary resection for localized colorectal tumors.
Epithelial ovarian carcinomatous and borderline components sometimes appeared in one patient. This study aims to analyze the genomic patterns of the carcinomatous and borderline components in the ovarian epithelial tissues. These tissues will be collected from paraffin section by microdissection to distinguish normal, carcinomatous and borderline tissues.
After standard multimodal therapy, the prognosis of relapsed and unresectable high-grade osteosarcoma is dismal and unchanged over the last decades. We have already finished a prospective trial about apatinib for advanced osteosarcoma(NCT02711007) and find it has a objective response rate of aproximately 45% with median progression-free survival around 5 months. Thus, the investigators explored apatinib activity together with anti-PD1 therapy in order to induce durable response in patients with relapsed and unresectable osteosarcoma after the failure of first-line or second-line chemotherapy. Apatinib is a small-molecule vascular endothelial growth factors receptor (VEGFR) tyrosine kinase inhibitor, similar to pazopanib, but with a binding affinity 10 times to VEGFR-2 comparing with pazopanib or sorafenib. SHR-1210 is a humanized anti-PD-1 monoclonal antibody.
Advanced soft tissue sarcoma patients who have previously recieved anthracyclines might still benefit from doxorubicin, ifosfamide and dacarbazine. However doxorubicin might be stopped using because of chronic cumulative heart toxicity. Several efforts have been made to improve the toxicity profile of conventional anthracyclines, including the use of liposomal encapsulation technology and the development of novel anthracycline analogs,such as pegylated liposomal doxorubicin and pirarubicin. However their actual effectiveness and toxicity have not been studied in prospective trial. The purpose of the study is to investigate whether they are available for this group of patients.
Breast cancer is one of the most serious threat to women's health of malignant tumors, also the most common causes of cancer death in women.Triple-negative breast cancer (TNBC) refers to the immunohistochemical detection of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (Her-2) are negative.Compared with other types of breast cancer, TNBC has a high degree of invasion,local recurrence and metastasis. Also,TNBC can not use endocrine therapy and lack of molecular targeting for Her-2 target therapy.Meanwhile other biological agents are too expensive,so the current clinical therapy only can use in China is chemotherapy,the average survival time is about 2 years. Fortunately,due to the impact of traditional Chinese medicine(TCM) in China, the majority of breast cancer patients have received varying degrees of TCM treatment, and because of TNBC patients can not be more mature endocrine therapy and anti-molecular targeted therapy Benefits, Chinese medicine play an important role in TNBC patients.TCM regulate immune function, inhibit tumor growth, Anti-recurrence and metastasis, to extend the survival of patients with tumor, and relative to chemotherapy drugs and molecular targeted drugs,improve the quality of life.In addition ,comparing with the biological agents,Chinese medicine prices are relatively low,and can be worth using widely. With the development of evidence-based medicine, and gradually recognize the importance of comprehensive treatment of breast cancer, Cancer Treatment Model has been proposed,.That is, to take Chinese medicine, surgery, radiotherapy and chemotherapy, endocrine therapy and biological immunization and other standardized, individualized comprehensive treatment. The introduction of evidence-based medicine into the field of research, will be beneficial to the objective evaluation of TCM syndrome differentiation in the treatment of refractory breast cancer in the characteristics and advantages in order to promote the use of. This study based on TCM syndrome differentiation and treatment, and adopts multi-center, randomized, double-blind and controlled research methods to evaluate whether the intervention of traditional Chinese medicine can improve the TNBC patients with disease-free survival (DFS), overall survival(OS),and the best time to intervene in traditional Chinese medicine; also the establishment of the exact effect, obvious advantages and evidence, can be promoted in line with clinical practice of the program, the formation of refractory breast Cancer and Western medicine combined with clinical path, and relying on the national clinical research base of Chinese medicine information platform, the construction of clinical information management cloud platform, the formation of active medical service process, the establishment of refractory breast cancer combined with clinical prevention and treatment center, improve the life quality level of TNBC patients. The study contains 5 locations,including Longhua Hospital, Shuguang Hospital,Yueyang Hospital,Zhejiang Traditional Chinese Medicine Hospital and Fudan University Cancer Hospital.Considering of the results of the study at MD Anderson Cancer Center in foreign countries showed that the 3-year survival rate of TNBC patients was significantly shorter than that of non-TNBC patients (74% vs.89%, P <0.01) To be at least 10% survival rate.At the same time, considering the case lost rate of 20%, calculated by PASS software, the number of samples for each group of 310 cases, a total of 620 cases of cohort study. According to whether to take traditional Chinese medicine,all the participants are divided into exposure group and non-exposure group, the number of observations per group is 310. Before the research, all participants needs to fill in the informed consent form, investigators introduce the clinical research related matters to them and record the basic situation. The Chinese medicine exposure group take Chinese medicine(San Yin Decoction ) besides of original Western medicine , non-exposed group only received Western medicine treatment, a total of two years.All results are recorded in the CRF table,and use SPSS18.0, Stata10.0 and other statistical software for data to analysis.
