A multi-center, open-label, study designed to evaluate the preliminary efficacy, safety and pharmacokinetics of RC108 in patients with c-Me-positive advanced digestive system malignancies.
The purpose of this study was to compare the accuracy and sensitivity of slow-pull capillary technique, traditional suction aspiration and non negative pressure puncture in the diagnosis of mediastinal and/or hilar lymph node enlargement by ultrasound bronchoscopic lymph node biopsy.
This project aims to investigate the therapeutic and repair effects of cord blood mononuclear cells (MNCs) on bone marrow failure after chemotherapy in children with malignant diseases. It is planned to collect 20 malignant children with bone marrow failure after chemotherapy and randomly divide them into two groups. The umbilical cord blood mononuclear cells were injected, ≥1×10^8 per infusion, once a week, and the recovery time of peripheral blood leukocytes, neutrophils, platelets and hemoglobin was observed. According to the recovery of myelosuppression, stop when the peripheral blood reaches leukocytes>1×10^9/L, neutrophils>0.5×10^9/L, platelets>25×10^9/L, and hemoglobin>60g/L at the same time. Use, share 1-4 times. Statistical software was used to compare the changes of peripheral blood leukocytes, neutrophils, platelets and hemoglobin before the start of the test (0d) and 1d, 3d, 5d, 7d, 10d, and 14d after the start of the test, as well as the severity of concurrent infections and antibiotic use Time, number of infusions of blood products.
Regular follow-up is essential to successful management of congenital ectopia lentis, but it is often ignored by parents in China. With rapid economic development, there are increasing numbers of mobile phone users that allow for communication applications to be used in medical care. The investigators aimed to assess the potential of the smartphone application assisted medical service to increase patient compliance in attendance of follow-up after congenital ectopia lentis treatment.
We obtained the occurrence of pain sensation, pain mood, sleep, etc. during endocrine therapy in breast cancer patients through telephone follow-up, and analyzed risk factors through artificial intelligence
The study is a prospective, single-center, single-arm, two-cohort, phase II clinical trial. Patients aged 18 years or older who had pelvic recurrence rectal cancer with or without resectable distant metastasis, with treatment naive disease (cohort A) or progressive disease after first-line chemotherapy (cohort B), Eastern Cooperative Oncology Group performance status of 0-1, will receive 25-40Gy/5Fx irradiation or 15-30Gy/5Fx reirradiation (pelvic radiation history), 18 weeks toripalimab and investigator's choice of chemotherapy, and stereotactic ablative radiotherapy (SABR) for all metastatic lesions between chemoimmunotherapy cycles, followed by multidisciplinary team (MDT) for decision:follow-up of complete response (CR), radical surgery, sustained treatment of non resection, or exit. The primary endpoint was local objective response rate. Secondary endpoints were extrapelvic objective response rate, R0 resection rate, duration of response, progression-free survival, overall survival, and safety and tolerability of the treatment. Shanghai Junshi Biomedical Technology Co., Ltd. Provides the first three cycles of toripalimab for free and has purchased liability insurance for clinical trial subjects.
To explore the safety and efficacy of GNC-038 in relapsed or refractory NK/T cell lymphoma, vascular immunomother T cell lymphoma, and other relapsed or refractory NHL, and to determine MTD, MAD, DLT, and RP2D of GNC-038, as well as its pharmacokinetic characteristics and immunogenicity.
Tumor bone metastasis refers to the metastasis of malignant tumors to the bone through lymph, blood or direct invasion to generate daughter tumors, which is the most common bone tumor. More than 40% of patients with malignant tumors will have bone metastasis, among which breast cancer, prostate cancer is more common, once the tumor cells occur bone metastasis, it means that the disease enters the advanced stage, posing a serious threat to the life safety of patients, therefore, early diagnosis of various primary malignant tumor bone metastases, can lay the foundation for clinical implementation of effective treatment measures. The laboratory of Hank F. Kung at the University of Pennsylvania has developed a new generation of 68Ga-labeled radiopharmaceutical P15-041 ([68Ga]Ga-HBED-CC-BP) based on existing phosphonate-targeting molecular probes (Figure 1). Data from preclinical studies indicate that P15-041 shows additional advantages in rapid and easy complex formation compared to current [68Ga]Ga-BPAMD, [68Ga]Ga-NO2AP-BP, [68Ga]Ga-DOTA- (ZOL). In vivo experiments, P15-041 showed good bone resorption and rapid renal excretion in normal mice. Haiyan Hong et al. [13] prepared multiple clinical doses of P15-041 and successfully evaluated it in patients, followed by intravenous P15-041, followed by a whole body PET/CT scan. Robert K. Doot et al. conducted dosimetric experiments on P15-041, analyzed the radioactive distribution of the drug in normal organs and the dynamic change of the dose of the drug in the body over time, and the results showed that P15-041 had high uptake in the bladder wall and bone cortex, blood and other tissues cleared quickly, and there was obvious radioactive enrichment in the myocardium in the early stage of imaging, and P15-041 had the potential to become a new generation of excellent phosphonate molecular probes.
New androgen pathway targeting agents (ARTA), including Abiraterone acetate, Apalutamide and Enzalutamide, are approved and used in treatment of metastatic hormonal sensitive prostate cancer(mHSPC). However, the development of castration-resistance prostate cancer(CRPC) is only a matter of time. The use of sequential ARTAs in mCRPC showed limited benefit in retrospective series and prospective trials. Therefore this sequence should be avoided because of known cross resistance and the availability of chemotherapy and poly adenosine diphosphate-ribose polymerase(PARP) inhibitors (if a relevant mutation is present). Recently, a randomized controlled trial(RCT), the ABIDO-SOGUG, indicated that compared with docetaxel, maintaining Abiraterone added to docetaxel in chemotherapy-naive patients who have experienced cancer progression to Abiraterone treatment could not improve radiographic progression-free survival or the other endpoints.However, another RCT, the PRESIDE trial, indicated that in patients who had progressed on Enzalutamide, continued Enzalutamide treatment in combination with docetaxel led to a significant improvement of PFS compared with placebo plus docetaxel. The aims of this trial is to assess both the efficacy and safety of docetaxel in combination with Enzalutamide as first-line treatment in mCRPC patients progressed on Abiraterone.
