Filter by:Although patients with locally advanced rectal cancer and resectable liver/pulmonary metastasis could benefit from surgery resection, these patients still have a poorer prognosis compared to those without distal metastasis. Based on previous studies, there is no confirmation of whether these patients could benefit from preoperative immunotherapy combined with conventional chemoradiotherapy. This study proposes a combination therapy, preoperative short-course radiotherapy followed by neoadjuvant chemotherapy and anti-PD-1 immunotherapy, for microsatellite-stable patients with locally advanced rectal cancer and resectable liver/pulmonary metastasis, to assess its impact on tumor retreat, decline of postoperative metastasis and recurrence, and the disease-free survival and overall survival of patients. Besides, this study will provide high-level medical evidence for future clinical treatment of patients with advanced rectal cancer.
This study is a retrospective, multicenter clinical study. The main objective is to analyze the risk factors affecting the recurrence of colorectal cancer patients with liver metastases who received radiofrequency/microwave ablation. Finally, we will construct a recurrence risk prediction model based on the risk factors and validated the model.
Sarcopenia is defined as reduction in muscle mass and function according to the criteria of the European Working Group on Sarcopenia in older people. Initially described for elderly patients, it is also presented as a negative prognostic factor in overall survival in oncology in certain locations (lung, ENT pathways, colon, pancreas) and more controversially for hemopathies. Its screening by measurement of skeletal muscle mass by CT scan and / or PET scan against L3 and by physical functional tests is not routinely integrated despite international recommendations. Sarcopenia is one of the characteristics of patient fragility that can induce more complications, lengthen the average length of hospital stay and reduce overall survival. The PRONOPALL score, a predictor score for survival validated by a previous study, will be correlated with the presence (or absence) of sarcopenia at inclusion for patients with a solid tumor (breast, ovary, prostate cancer , kidney, lungs, pancreas, colorectal). A prospective study on 38 patients with metastatic cancer was carried out at the Victor Hugo clinic in Le Mans between 01/JUN/21 and 31/AUG/21 (SPACE, ClinicalTrials.gov number, NCT04714203): 25 patients were analyzable on the CT and PRONOPALL score data with a prevalence of sarcopenia of 60% and median overall survival of 14 months (unpublished data), clinical performance and muscle strength tests were not carried out (as in the publications cited above). A prospective study for the detection of sarcopenia is indicated by extending to blood diseases with the integration of clinical tests included in the initial APA (Adapted physical activity) assessment recommended for diagnosis.
A prospective, open-label, multi-center, single-arm study of Almonertinib combined With Bevacizumab for EGFR-mutant NSCLC patients with leptomeningeal metastasis.
Currently, comprehensive treatments for liver metastasis/pulmonary metastasis that cannot reach NED include systemic chemotherapy, interventional chemotherapy, molecular targeted therapy, immunotherapy, and local treatments (ablation therapy, radiation therapy, etc.) for liver metastases. Combination therapy model of local ablation, systemic chemotherapy, and anti-PD -1 monoclonal antibody hopefully can prolong patient survival. This trial will evaluate the effectiveness and safety of carrelizumab combined with microwave ablation and chemotherapy in the treatment of colorectal cancer liver metastasis/pulmonary metastasis
Liver Transplantation for Unresectable GIST Liver Metastases
Breast cancer ranks as the top leading malignant tumors among females, and also accounts for the most common cause of tumor related mortality in females worldwide. Approximately, 20-30% of breast cancer cases develop metastasis, while 50% of patients will suffer from breast cancer liver metastasis. The proper indication for surgical treatment of breast cancer liver metastasis is still a matter of discussion. Surgery is becoming more practical and effective than conservative treatment in improving the outcomes of patients with breast cancer liver metastasis and liver metastasis surgery is included in an onco- surgical strategy.
This is a prospective, randomized, 2-arm, Phrase 2, superiority and multicenter study to compare the efficiency of Anti-HER2 TKI versus Pertuzumab in Combination With Dose-dense Trastuzumab and Taxane in HER2-positive breast cancer patients with active refractory brain metastases.
Almonertinib is a three-generation epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI), which has shown competitive potential in the second-line treatment against first-generation TKIs. This study intends to assess the efficacy and safety of stereotactic radiosurgery with sequential almonertinib in treatment-naive EGFR-mutant NSCLC patients with brain metastases.
After stereotactic radiosurgery (SRS) of brain metastases, patients undergo a standard brain magnetic resonance imaging (MRI) to assess treatment response 12 weeks after completion of treatment. The interpretation of this standard MRI can sometimes be challenging as it can be difficult to differentiate tumour getting bigger/returning (progression/recurrence) from expected radiotherapy treatment-related changes known as radionecrosis. This study is a pilot brain imaging study that is investigating if readily available forms of imaging such as contrast-clearance analysis MRI (also known as TRAMs) and/or 18 Fluoromethyl-choline positron emission tomography/computerised tomography (18F-choline PET/CT) are equivalent to multi-parametric MRI in their ability to differentiate tumour from radionecrosis. Multi-parametric MRI has the most evidence for its ability to discriminate tumour from radionecrosis but is resource intensive and not routinely available in most centres.
