Filter by:This study will test whether reduced-dose radiotherapy is an effective treatment for metastatic tumors with an ATM mutation. The researchers want to find the lowest dose of radiation that would still be effective to treat these tumors.
Gastric cancer with retroperitoneal lymph node metastasis was considered as unresectable, to improve these patients' prognosis, we designed systematic conversion therapy including immunotherapy and chemoradiotherapy. The purpose of this study is to estimate safety and efficacy of Sintilimab in combination with chemoradiothrapy followed by D2 surgical resection in patients with advanced gastric cancer with retroperitoneal lymph node metastasis.
This research is being done to see how effective the drug niraparib is against cancer that has metastasized to the central nervous system (CNS). - This research study involves the study drug niraparib.
A registry-based randomized phase II trial. A total of 46 patients with metastatic head and neck cancer on systemic therapy with oligoprogression to 1-5 extracranial lesions will be randomized using a 1:1 ratio to standard of care (begin next-line systemic therapy, best supportive care, continue current systemic line, based on treating physician decision) vs. receive stereotactic ablative radiotherapy to all oligoprogressive lesions while continuing their current systemic therapy.
CT-Staging is crucial for therapy planning of patients with malignancies. Dose efficiency and image quality are important parameters for these examinations. Up to now, scientific evidence of dose efficiency of modern CT scanners is mostly derived from retrospective analyses. This prospective study systematically analyzes dose efficiency and image quality of three modern CT scanners by randomization of patients who are scheduled for a CT scan to examine the status of malignancies. After giving informed consent and randomization (1:1:1), the CT scan will be performed at one of the modern CT scanners available at our department. This will allow a systematic allocation to the different scanners.
The primary research purpose is to evaluate the diagnostic efficacy of 68Ga-PSMA PET in metastatic lesions of locally advanced and advanced renal cell carcinoma, and to compare with that of enhanced CT. The second purpose is to evaluate whether 68Ga-PSMA PET can change the treatment decision of patients with locally advanced and advanced renal cell carcinoma
This is a single center phase I, first-in-human, dose escalation study of FLASH therapy in patients with metastases of melanoma. The trial is based on escalating single doses of FLASH therapy administered to skin melanoma metastases using the Mobetron® with high dose rate (HDR) functionality. The aim of the study is to evaluate a dose escalation of high dose rate radiotherapy (FLASH therapy) as single dose treatment for skin melanoma metastases that progress locally despite systemic treatments. Melanoma is a typically radio-resistant tumor type, which can justify such a dose escalation with a new type of radiotherapy that appears much better tolerated than conventional radiotherapy.
This is an observational study to investigate if it is feasible to recruit 100 patients receiving radiotherapy (RT) to metastatic disease to wear Hexoskin and if Hexoskin will facilitate the monitoring, detection and early treatment of RT-related side effects.
Complete mesocolic excision is currently recognized as a standard procedure for colon cancer. Controversy remains on the presence of right gastroepiploic mesentery metastasis in patients with colon cancer locating at or close to the hepatic flexure. The investigators design this study in order to define the incidence of mesogastrium metastasis and analyse the safety and surgical outcome in these patients who undergo complete mesocolic excision with right gastroepiploic mesentery resection.
Subject population：Patients with brain metastases from EGFR mutation-positive non-small cell lung cancer who have not received systemic treatment. Experimental design: Single-center, single-arm phase II clinical trial. Purpose: Efficacy and safety of Anlotinib combined with Almonertinib in the treatment of patients with brain metastases from EGFR mutation-positive non-small cell lung cancer. treatment plan: 1). Anlotinib: 12mg/time (BSA≥1.6 m2) or 10mg/time (BSA<1.6 m2), once a day orally, taking two weeks and stopping for one week; 2). Almonertinib: 110mg, orally once a day; primary endpoint: Intracranial progression-free survival (iPFS); secondary endpoint: Objective intracranial response rate (iORR=iCR+iPR), intracranial disease control rate (iDCR=iCR+iPR+i SD), overall progression-free survival (PFS), overall survival (OS), quality of life score.
