Filter by:The main purpose of this research is to verify the safety of CEA targeted chimeric antigen receptor T cells and to determine the proper dosage of CAR T cells infused.
This is a single arm, open label trial to assess the safety and efficacy of tucatinib in combination with pembrolizumab and trastuzumab for the treatment of HER2+ breast cancer brain metastases (BCBM). A total of 33 patients with untreated or previously treated and progressing HER2+ BCBM not requiring urgent central nervous system (CNS)-directed therapy will be enrolled. The study will determine the recommended dose of tucatinib in this combination and assess the efficacy of this combination in controlling CNS disease in patients with HER2+ BCBM.
For patients with unresectable colorectal cancer liver metastases, preclinical studies have shown that after the resistance of cetuximab, the treatment sensitivity can be restored by stopping cetuximab for a period of time. This is called the cetuximab re-challenge. And the circulating tumor DNA (ctDNA) test is reported a biomarker for the efficacy of cetuximab rechallenge. However, there is still no randomized controlled trial for verification. This study aims at patients after the first-line treatment of cetuximab has progressed. After the second-line non-cetuximab treatment has progressed, the effects of re-application of combined with cetuximab and chemotherapy alone are compared to verify the re-challenge effect.
Liver metastasis may not be detected by CT and MRI due to their small size while they can be detected by EUS. Also, EUS-FNA has a great impact in improving the diagnostic accuracy of EUS. Objectives: To assess the feasibility of EUS in the detection of occult small hepatic focal lesions at the time of primary tumor staging, not seen by CT or MRI.
The purpose of this study is to evaluate a new radiation planning and treatment delivery technique called Deep Inspiration Breath Hold (DIBH) and expiration technique. This technique will be used to treat patients who have tumors close to the chest wall and are candidates for Stereotactic Body Radiation Therapy (SBRT). This study will assess the reduction of radiation to the chest wall during treatment using this technique.
This is a phase II, Open-Label, Multicenter, Prospective Clinical Study to Investigate the Efficacy and Safety of Tislelizumab Combined with Pemetrexed/ Carboplatin in Patients with Brain Metastases of Non-squamous Non-small Cell Lung Cancer. The primary end point is PFS, and secondary endpoint is ORR, OS, DoR and Neurocognitive impairment. during the study, the exploratory objectives including (1) PD-L1 expression, TMB, and other potential predictive biomarkers, correlated with response to treatment (2) Progression-free survival based on intracranial response (iPFS) according to RECIST 1.1 and RANO-BM
The esophageal squamous cell carcinoma (ESCC) has high prevalence and mortality in China, which become a severe challenge for public health. The molecular imaging technology has been developed for visualization and precise diagnosis of the tumors. Integrin αvβ3 is a specific marker for tumor. Noninvasive visualization and quantitative analysis of integrin αvβ3 expression provide new opportunities for tumor diagnosis, identification and efficacy monitoring. The peptide containing Arg-Gly-Asp (RGD) can specifically bind to integrin αvβ3 receptor with high selectivity and affinity to achieve the detecting tumor .The SPECT/CT with 99mTc-3PRGD2 has a high specificity in the diagnosis of mediastinal lymphnode metastasis and a greater value in the decision-making of lymphnode dissection. This study is a single-center self-controlled study, It is planned to enroll 30 patients with esophageal cancer , preliminarily confirmed by endoscopic biopsy, . After intravenous injection of 0.3 mCi/kg of 99mTC-3PRGD2, patients underwent single-photon emission computed tomography/computed tomography (SPECT/CT) examination.Subsequently, the patients received chest/abdomen enhanced CT and 18F fluorodeoxyglucose (18F-FDG) positron emission computed tomography /CT (PET/CT) for diagnosis. According to the determination of the researcher, patients who were suitable for surgery received surgery to obtain surgical pathology; For patients who were not suitable for surgery, ultrasound-guided lyphnode biop was performed .In this study, pathological specimens were obtained from gastroscopy, surgical pathology, or ultrasound-guided lymph node biopsy. The diagnostic accuracy, sensitivity , specificity and safety of SPECT/CT with 99mTc-3PRGD2 were evaluated and compared with PET-CT and enhanced CT.
STEP is a French multicentre, prospective, non-randomized, phase II study designed to assess 6-months local control after pre-operative stereotactic radiosurgery (SRS) for patients with brain metastases
To evaluate the potential usefulness of 68Ga-DOTA/NOTA-FAPI-04 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various types of cancer.
Vertebra is one of the most common site of metastatic disease, which may cause severe pain or neurological deficit. Decompressive surgery or radiation therapy are of limited efficacy and recurrence is very likely. Debulking surgery usually has better local control and survival benefit. However, debulking surgery often accompany with massive blood loss, which may cause hemorrhagic shock or death. It is known that intraoperative blood loss is associated with tumoral vascularity. However, there is current no objective method to evaluate vascularity status. On the other hand, preoperative embolization is considered as major method to decrease blood loss. There is also objective method to evaluate the embolization effect. By our innovative dual energy computed tomography angiography - digital subtraction angiography (CT-DSA), the tumoral vascularity status and embolization effect of spinal tumor can be objectively assessed. We aim to utilize CT-DSA to investigate spinal tumor, in a hope to find out correlation of vascularity status, embolization method, and surgical outcome, which can help individual disease status and tailored treatment decision.
