Filter by:Whole brain radiotherapy (WBRT) has long been a practical and effective therapeutic modality for various settings of management in radiation oncology. For example, the indications for WBRT should include brain metastasis or metastases, the setting of prophylactic cranial irradiation (PCI) used mainly for patients with limited-stage small cell lung cancer, and even some patients with extensive-stage small cell lung cancer. The rationales for WBRT are essentially based on that it can target both microscopic and gross intracranial disease. In addition to providing rapid alleviation of neurologic symptoms and enhanced intracranial disease control, WBRT might also prolong the time to develop neurocognitive function (NCF) decline. However, paradoxically NCF decline can also occur due to a sequel of WBRT. In terms of the time course of WBRT-induced NCF decline, it might vary considerably according to the specific domains which are selected to be measured. Early neurocognitive decline occurs within the first 1 - 4 months after WBRT for brain metastases. The domains of early neurocognitive decline principally involve verbal and short-term memory recall. Since several decades ago, it has been understood that hippocampus plays an essential role in memory function. Not little evidence supports that radiation-induced damage to hippocampus should be strongly associated with NCF impairment. Furthermore, several studies have shown that isodose distribution in hippocampus is closely related to neurocognitive function in patients with benign or low-grade brain tumors. As a consequence, it is hypothesized that conformal hippocampal sparing during the course of WBRT (HS-WBRT) might provide significant preservation in terms of cognitive function. This prospective cohort study aims to explore and evaluate the impact of the delivery of HS-WBRT on the pattern of NCF change and the extent of NCF decline in patients receiving prophylactic or therapeutic WBRT. As compared with previous related and relevant studies, it will also be investigated whether neurocognitive functional preservation can be achieved via the integration of hippocampal sparing with the course of WBRT.
This Phase 3, open-label, triple arm study aims to evaluate the overall survival (OS) of fotemustine versus the combination of ipilimumab and fotemustine or the combination of Ipilimumab and nivolumab in patients with metastatic melanoma with brain metastasis.
This is a Phase I dose escalation and expansion trial. The purpose of this study is to determine the maximum tolerated dose of radiation received during stereotactic radiosurgery in patients with brain metastases who have never received radiation to the brain before.
1. Compare the effect and safety of gefitinib alone with gefitinib plus concomitant WBRT(whole-brain radiotherapy ) in treatment of NSCLC patients harboring an EGFR mutation with multiple BM. 2. Verify the failure pattern of NSCLC patients harboring an EGFR mutation with multiple BM. 3. Explore the rescuable therapy after progression of disease.
This is a multi-center phase II randomized controlled study to assess the efficacy of Pemetrexed/cisplatin with or without Bevacizumab on patients with brain metastasis from non-small cell lung cancer(NSCLC) harboring EGFR wild type by intracranial PFS(iPFS),also PFS ,DCR and OS.The side effect is evaluated as well.
This is a multi-center phase III randomized controlled study to assess the efficacy of Gefitinib alone and Gefitinib combination with Pemetrexed/platinum on patients with brain metastasis from non-small cell lung cancer(NSCLC) harboring EGFR mutation type by intracranial PFS(iPFS),also PFS ,DCR and OS.The side effect is evaluated as well.
This project is aim to explore non-increased-intracranial-pressure symptomatic brain metastases of NSCLC, and if the OS of secondary brain radiotherapy after recurrence with Erlotinib is better than Erlotinib with concurrent brain radiotherapy. Treatment group are treated with Erlotinib until brain tumor progression, then gave brain radiotherapy, and continued to take Erlotinib till extracranial lesions progression. Control group are Erlotinib with concurrent brain radiotherapy, and continued to take Erlotinib after radiotherapy until recurrence or termination for other reasons.
Brain metastases, a common complication,occur in 25-40% of patients with non-small cell lung cancer (NSCLC). Whole-brain radiation therapy(WBRT) and Stereotactic Radiosurgery (SRS) are important approaches to the treatment of brain metastases from NSCLC. Known to us, epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) can pass through the blood-brain barrier and show promising antitumor activity against brain metastases from NSCLC, especially for EGFR mutation patients. However, due to the lower concentration of tyrosine kinase inhibitors (TKIs) in the cerebrospinal fluid and its inevitable emergence of drug resistance, brain metastases will be refractory or resistant to standard-dose EGFR inhibitors. Icotinib is one agent of EGFR-TKIs. The previous studies have shown that the Icotinib conventional dose (125mg, TID) is far from reached its maximum tolerable dose. It is a challenge whether the further dose escalation of Icotinib will enhance its concentration in cerebrospinal fluid and thereby improve its therapeutic effect. Here the investigators examine the therapeutic effect and side-effect of double dose of Icitinib in treating patients with brain metastases from NSCLC who have suffered from the failure of conventional dose treatment.
Adjuvant whole-brain radiation therapy (WBRT) after resection of single brain metastasis is considered as a standard associated with side effects leading to decreased neurocognitive function. The Investigators addressed the question whether stereotactic radiotherapy of the resection cavity impairs neurological status and/or cognitive functions in compare to adjuvant WBRT.
The investigators plan to study high dose, single treatment radiation, using a plastic mask instead of a head frame that pins into a patient's skull. The investigators need to (1) quantify set-up accuracy and patient motion during radiation treatment and (2) ensure that without the head frame the tumour control rate and risk of complications are similar to our previous experience using the head frame.
