Active clinical trials for "Neoplasm Metastasis"

The purpose of this study is to evaluate the safety of liver resection for metastatic, resectable lesions from colorectal cancers after systemic chemotherapy.

Brain metastases (BM) are the most common intracranial tumors in adults and source of the most common neurological complications of systemic cancer. Surgery and radiation therapy are the most important components in the management of BM with the goal to prolong survival and improve the quality of life. Whole brain radiotherapy (WBRT) has shown to increase local and distant control both with and without surgical resection. However, patients who develop a new or recurrent BM after WBRT and undergo resection are left without adjuvant therapy options. Local recurrence particular in patients with single metastasis does effect both survival and quality of life. In individual cases the option of additional radiotherapy has been suggested and applied. We seek to evaluate the addition of a stereotactic radiosurgery (SRS) boost to the resection cavity both as adjuvant and salvage procedure among patients, who undergo resection of a BM and previously received WBRT or decline WBRT. Goal is to show superior local brain control.

RATIONALE: Monoclonal antibodies, such as cetuximab and bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor.Drugs used in chemotherapy, such as leucovorin, oxaliplatin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving cetuximab together with combination chemotherapy and bevacizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery. PURPOSE: This randomized phase II trial is studying the side effects and how well giving cetuximab together with leucovorin, oxaliplatin, and fluorouracil works with or without bevacizumab in treating patients with resectable liver metastases from colorectal cancer.

The FIRE-3 trial is a multicenter randomized phase III trial investigating 5-FU, folinic acid and irinotecan (FOLFIRI) plus cetuximab versus FOLFIRI plus bevacizumab in first line treatment of metastatic colorectal cancer. Planned accrual is 284 evaluable patients per treatment arm. The primary study endpoint is objective response rate. Secondary endpoints are median progression free survival, median overall survival, safety, and secondary resection rate.

The aim of the study is to assess prospectively the impact of radiosurgery on the quality of life in patients with brain metastases.

The purpose of this clinical research study is to answer the following questions using 18F-fluoromisonidazole as an imaging agent: Do cells exist in human tumors that are at very low oxygen levels (hypoxic cells)? If hypoxic cells exist in human tumors, do they effect the ability of radiotherapy to control human tumors? Can Positron Emission Tomography (PET scanning) detect hypoxic cells in human tumors?

Surgical resection has offered the best option for prolonged survival in patients with colorectal liver metastases. Limiting factor for major liver resections is the size of the future liver remnant (FLR). In case of normal liver function, 30% of the total liver volume is considered to be sufficient to maintain adequate liver function after resection. In an attempt to further increase "resectability" criteria for patients with too small FLR surgical and interventional maneuvers such as portal vein embolization and portal vein ligation in two-stage hepatectomies have been implemented, but they need an interval of 4-8 weeks to achieve sufficient hypertrophy. In order to obtain adequate but rapid parenchymal hypertrophy a new surgical two-step technique, ALPPS, was introduced for oncological patients requiring extended hepatic resection with limited functional reserve. Both procedures can be performed with acceptable morbidity and mortality. The investigators conclude that it is time to perform a randomized study comparing the two surgical approaches in regard to oncological outcome.

To compare presurgical motor mapping by navigated transcranial magnetic stimulation for surgery (nTMS) of rolandic lesions to surgery with mapping without implementing these data into neuronavigation as control. Primary objective: Permanently new postoperative deficit is lower when the preoperative motor mapping is available to the surgeon
