Filter by:Patients with oligometastatic squamous cell carcinoma were enrolled and randomly assigned to receive either PD-1 inhibitor +/- chemotherapy combined with local therapy or PD-1 inhibitor +/- chemotherapy alone. The primary end point was progression-free survival (PFS). The secondary end points included overall survival, side effects and local control.
[Study objectives] To evaluate the efficacy and safety of the combined treatment of radiotherapy and endoscopic intraductal radiofrequency ablation in patients with locoregional extrahepatic cholangiocarcinoma.
The goal of this prospective phase II study was to determine whether personalized planning-based nCRT for LARC would indeed decrease small bowel dose, and whether selected plans, specifically prioritizing lower dose to small bowel, would result in lower rates of acute GI toxicity compared with previously reported rates.
The goal of observational study is to learn about the outcomes of the participants. The main questions it aims to answer are: 1. ESD additional postoperative radiotherapy in patients with non healing SESCC overall survival (OS) and disease-free survival (DFS) 2. The adverse events (AE) of additional radiotherapy after ESD for non-curative SESCC patients were counted, and its safety was evaluated. Participants will receive radiation therapy as necessary.
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide, with a 5-year survival rate of less than 50%. Radiotherapy is an important measure to control tumor recurrence. Although radiotherapy has been widely used in patients with head and neck squamous cell carcinoma, the 2-year local recurrence rate of patients with locally advanced disease is still as high as 50%-60%, and the distant metastasis rate is as high as 20%-30%. This is associated with a lower radiosensitivity in HNSCC. Our previous study has confirmed that type I collagen secreted by cancer-associated fibroblasts (CAFs) can enhance the radioresistance of head and neck squamous cell carcinoma. We also confirmed that pirfenidone could reduce type I collagen expression in CAFs and enhance radiosensitivity in vitro and in vivo. Therefore, we plan to translate the basic research into clinical practice and conduct a prospective interventional phase II clinical trial to investigate the safety and efficacy of pirfenidone as a radiosensitizer in HNSCC.
The purpose of this clinical trial is to explore the impact of En bloc surgery and separation surgery combined with radiation therapy on the prognosis and survival of patients with spinal oligometastatic cancer, describe the clinical results, and optimize future treatment goals
This study is a randomized controlled phase II trial to evaluate the efficacy of the combination of stereotactic body radiation therapy (SBRT) and immunotherapy with postoperative chemotherapy in colorectal cancer liver metastasis (CRLM) patients with high risk of locally recurrence. Researchers will compare the combination therapy with the postoperative chemotherapy alone to see if postoperative chemotherapy plus SBRT and immunotherapy can further reduce the risk of recurrence and metastasis after surgery.
This study aims to help to screen out appropriate cases for consolidation therapy and more intensive follow up.
In the HOBBIT-trial by Vakaet et al. A protocol was developed to increase breath-hold time using (voluntary) hyperventilation and oxygenation to achieve DIBH times around 3 minutes. Multiple non-medical interventions are being investigated to prolong a L-DIBH that are feasible in clinical practice. One of these methods will be to alter the time perception of the subjects. It has been noted in multiple studies (both medical and not) that slowing a person's perception of time results in an increase in breath-hold time. This alteration in time perception can be achieved with the use of a slowed clock as well as the usage of mental or physical exercises to preoccupy the subjects. Volunteers will then be randomised into either the standard arm or the intervention arm. The intervention arm will follow standard protocol regarding DIBH preparation, though during the L-DIBH they will be asked to perform a simple mental exercise on a tablet. After 2 sessions of 3 L-DIBHs each, there will be a cross-over to the other arm in order to ascertain comfort and preference with each technique.
This research study will evaluate the efficacy and safety of stereotactic radiotherapy (SRT) combined with Trastuzumab-Deruxtecan (T-DXd; DS-8201a) in HER2-positive Breast Cancer Patients with newly diagnosed or progressing Brain Metastases.
