Filter by:Radiation therapy is a crucial part in the comprehensive treatment of breast cancer. In recent years, emerging systemic treatment regimens such as HER 2 inhibitors, CDK 4/6 inhibitors, PARP inhibitors, capecitabine and PD1 inhibitors have greatly improved the prognosis of breast cancer and has become the standard treatment for specific populations. A considerable number of patients require both radiotherapy and maintenance systemic therapy. However, it is not clear whether systemic therapy should be synchronized or suspended in radiotherapy，despite that previous basic research shows that some molecular drug therapy and radiotherapy has a clear synergy mechanism. There is an agent need for a definite evidence to evaluate the safety of synchronous treatment, to support clinical diagnosis and treatment and the next step of comprehensive treatment. The implementation of the new radiotherapy technology represented by IMRT takes into account the prescription dose homogenization and the minimization of normal tissue dosage, which provides a certain basis for the combination therapy. Based on the above conditions, this study intends to enroll patients between 18 and 70 years old with chest wall / breast ± lymphatic drainage area and requiring capecitabine, CDK 4/ 6 inhibitor, HER2 targeted therapy or immunotherapy. Radiation and novel systemic therapies would be delivered concurrently. The study aimed at evaluating the safety of combined treatments.
This trial will treat patients with platinum resistant ovarian, fallopian tube or primary peritoneal cancer as defined by a progression free interval within six months of completion of most recent platinum-based treatment with a combination of vismodegib and atezolizumab. Despite recent improvements in treatment of ovarian cancer with the introduction of PARP inhibitors, response rates to therapy in the platinum resistant setting remain dismal with response rates of only 10-20% reported for single agent cytotoxic therapies. Given the poor prognosis and limited treatment options for these patients, this population is considered appropriate for trials of novel therapeutic candidates.
Homologous recombination deficiency (HRD) is an important molecular biomarker for Poly (ADP-ribose) polymerase inhibitors (PARPi) which is a significant progress in the treatment of ovarian cancer. However, the proportion of HRD positive in real world and relationship of HRD status with PARPi in Chinese ovarian cancer patients remains unknown.
Epithelial ovarian cancer (EOC) is the most lethal gynecological malignancy. PARP inhibitors(PARPi) are an important progress in EOC treatment. The available evidence suggests that BRCAmt or HRD-positive is an effective biological marker for PARPi. However, in our previous clinical observation, it was found that the tumor burden may be the potential clinical markers PARPi. We intend to develop a real-world study to confirm the potential clinical markers and explore new clinical markers for PARPi.
The Stupp protocol is the standard treatment of glioblastoma multiform (GBM) which prognosis remains poor. The non-dividing nature of normal brain cells provides an opportunity to enhance the therapeutic ratio by combining radiation with inhibitors of replication-specific DNA repair pathways such poly(ADP-ribose) polymerase (PARP) inhibitors, thus inducing more cytotoxic effects of DNA-damage related to treatment modalities, including alkylating reagents like temozolomide (TMZ). Olaparib, a potent PARP inhibitor, overcomes apoptotic resistance and sensitizes GBM cells for death receptor-mediated apoptosis induced by TRAIL (Tumor necrosis factor-Related Apoptosis Inducing Ligand). Moreover, inhibition of PARP activity increases cellular sensitivity to ionizing radiation: it was even suggested to be more pronounced in tumors than in normal tissue. Lastly, progress in technical imaging and intensity-modulated-radiotherapy (IMRT) techniques provide new possibilities for sparing healthy tissues.
