Filter by:To evaluate if the addition of liver transplantation primarily utilizing liver grafts from extended criteria donors not utilized for approved indications to conventional treatment of non-resectable/ non-abatable colorectal liver metastases (CLM) increases overall survival compared to best alternative care.
This study is being done for the following reasons: The study has two parts. The purpose of the first part (Phase I) of the study is to find out the highest dose of Afatinib that can be given safely with T-DM1. The purpose of the second part of the study (Phase II) is to find out whether the dose of Afatinib with T-DM1 determined in Phase I will keep breast cancer from getting worse for a period of time.
This study will collect data on Canadian cancer patients that have uncommon/rare changes in their tumours, such as alterations/rearrangements in the genetic material inside cells - known as deoxyribonucleic acid, or DNA, which acts as a map and gives directions to the cells on how to make other substances the body needs - because some of these changes have been found to respond to different drugs that help to stop the cancer. These rare changes occur in genes such as but not limited to ALK, EGFR, ROS1, BRAF, and NTRK which have targeted drugs in a family known as tyrosine kinase inhibitors (TKIs), and KRAS G12C mutation, which now has a targeted inhibitor drug therapy for patients with non small cell lung cancer (NSCLC). The goals for the study are to compare the natural history of such cancers and the treatment outcomes, including toxicities and patient-reported outcomes, for the different therapies.
Leptomeningeal metastasis (LM) is a devastating and terminal complication of advanced non-small-cell lung cancer (NSCLC), especially in patients harboring epidermal growth factor receptor (EGFR) mutations. Osimertinib is an oral,third-generation, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR T790M resistance mutations .AURA I/II study and other preclinical study suggested that Osimertinib exhibited a better blood-brain barrier(BBB) penetration than the other EGFR-TKIs (gefitinib, erlotinib, or afatinib).The BLOOM 、AURA and FLURA study demonstrated that osimertinib showed encouraging activity and manageable tolerability in pretreated EGFR-mutant NSCLC patients with LM. Bevacizumab is a monoclonal antibody against vascular endothelial growth factor (VEGF). Animal study and autopsy specimens showed that VEGF is an essential factor in LM. Recently study showed EGFR-TKIs plus bevacizumab prolonged PFS and OS in patients with EGFR-mutant NSCLC and multiple brain mteastasis when compared with EGFR-TKIs alone. Howerver osimertinib combined with bevacizumab could benefit patients with LM from EGFR- mutant NSCLC remains undetermined. Therefore, the purpose of the study is to evaluate the safety and efficacy of osimertinib combined with bevacizumab for EGFR- mutant non-small cell lung cancer with leptomeningeal metastasis
Bone radioiodine (RAI) uptake without structural abnormality in thyroid cancer (TC) patients may be related to false positive or to microscopic foci of metastatic tissue. In such cases, outcome is reported to be excellent. Indeed, Robenshtok et al. reported a serie of patients with RAI-avid bone metastases of TC without structural abnormality on imaging studies who have more favorable long-term prognosis than those harbouring structurally visible bone metastases and do not undergo skeletal-related complications. The investigators report the case of Mrs D., who had been operated for a pathologic tumor stage 3: pT3(m) poorly differentiated TC at the age of 43. The first post-therapeutic whole body scan revealed 3 foci of bone uptake (right clavicle, L2, L3). The elevated level of thyroglobulin (157ng/mL) favoured the hypothesis of bone metastases despite the absence of any structural lesion on CT and MRI. She received 7 courses of radioiodine therapy. The right clavicle RAI uptake persisted, and subsequent CT disclosed an osteolytic lesion which was treated by radiofrequency and external beam radiation. Twenty-five years after the diagnosis, she has a persistent morphological disease with a 30x8mm progressive lesion on the right clavicle, for which surgery is planned. The aim of the present study is to describe the natural history and evolution of radioiodine avid bone metastases from thyroid cancer without structural abnormalities and to identify prognosis factors.
Luminal A breast cancer is a kind of breast cancer with low rate lymph node metastasis and good survival. But in clinical practice, Luminal A breast cancer can present with early, unexpected lymph node metastasis some time, indicates poor survival. Silent information regulator 2 homolog 1 (SIRT1) plays a different role in breast cancer with different molecular typing. Previous study supports a role of SIRT1 protein as tumor suppressor in Luminal A breast cancer, in association with apoptosis-related proteins. The epithelial-to-mesenchymal transition(EMT) process results in loss of cell-cell adhesion, increased cell mobility, and is crucial for enabling the metastasis of cancer cells. But no similar study in Luminal A breast cancer. Hence, this study will 1) investigate the expression pattern of SIRT1 in primary tumor and lymph node metastasis; 2) investigate the different expression pattern of SIRT1 in T2/T3 , lymph node negative tumor and T1, lymph node positive tumor; 3) investigate potential role of SIRT1 enzyme in regulating cell migration and invasion in Luminal A breast cancer cells.
This is a master prospective Phase I-II trial evaluating feasibility and efficacy of stereotactic magnetic resonance (MR) guided adaptive radiation therapy (SMART) in patients with cancer. - The phase 1 study will evaluate the feasibility and safety of delivering SMART in patients with cancer. - Phase 2 will evaluate efficacy of SMART with specific reference to tumor control and improvement in patient reported outcome measures
This clinical trial will be conducted as a single-center, open-label, Phase I/2 trial to evaluate the feasibility and safety of Yttrium-90 radioembolization (Y90-RE) in combination with a fixed dose of of immunotherapy (durvalumab - 750 mg) in subjects with liver-predominant, metastatic colorectal cancer (mCRC), which is mismatch repair proficient/microsatellite stable (pMMR/MSS).
The main objective of this trial is to determine feasibility and tolerance of the human body to RFA associated with local immunomodulation carried out using a thermoreversible hydrogel combined with 2 immunomodulators, GMCSF and Mifamurtide. The main endpoint of the study is the feasibility, the frequency and the nature of per and post-operative adverse events of the in situ injection of an immunomodulatory hydrogel after radiofrequency of unresectable colorectal liver metastases. The secondary objective is one-year progression free survival rate.
The present hypothesis is that anti-EGFR agents are active in tumors with low-level RAS mutation when the majority of tumor cells is still sensitive. While response rate may be high and may reflect sensitivity to anti-EGFR agents, PFS is anticipated to be shorter than in RAS wild-type patients due to the faster development of resistance when sensitive cells are eradicated and when the RAS-mutant anti-EGFR resistant clones become predominant. The characteristics of low-level RAS mutant tumors would be: - Objective response rate (ORR) high (reflecting the sensitive clone) - Progression-free survival (PFS) short (reflecting the more rapid outgrowth of RAS mutant clones)
