Filter by:To acquire data during High Dose Rate (HDR) brachytherapy treatments aiming to track the brachytherapy source inside the patient verifying the delivery of the treatment plan. Medical images (CT,MRI and US) combined with software developed by the investigator will be employed to predict the response of the Investigational product during the treatment and will be used as reference.The IP will be placed on the side of the treatment table and will acquire data during the whole treatment, which will be compared against information derived from the treatment plan. The IP based method can detect errors and information about motion and treatment uncertainties that are not currently available.
The goal of this open label, randomized, controlled clinical trial is to assess the benefits of providing Reiki therapy to subjects receiving their first brachytherapy treatment for gynecological malignancies. Participants will either receive a session of Reiki therapy or usual care during the standard wait time between the placement of the brachytherapy device and brachytherapy treatment. Questionnaires will be administered at various time points on the day of the participant's first brachytherapy treatment as well as at the three month follow-up time point. Researchers will compare the intervention (Reiki therapy) and control (usual care) groups to assess the impact of the Reiki therapy on anxiety, pain, state anxiety, depression, and physiological measurements.
To evaluate the effectiveness and safety of radioactive particles in combination with the PARP inhibitor fluzoparib in the treatment of advanced inoperable soft tissue sarcoma.
Phase 1-2 study, comparing ultra-hypofractionnated (UH) to a moderately hypofractionnated (MH) radiation therapy, with image guided HDR prostate brachytherapy. Using iso-equivalent doses, a non-inferiority analysis will be done in order to prove UH non-inferior to MH, toxicity wise. Acceptability, tolerability, acute and late toxicity will be reported. MRI visible dominant intra-prostatic lesion will be outlines and variability between radiation oncologists and radiologists will be reported. As secondary objective, biochemical and clinical failure free survival will be reported at 5 & 10 years.
Brachytherapy for gynecological cancers will be studied retrospectively.
Within our institution, the principal investigator have acquired expertise in endorectal brachytherapy, a localized treatment for colorectal cancer. Until now a modality which uses an endorectal applicator has been used, which has certain limitations. In the context of this study, a new applicator will be used which is already approved by Health Canada for endorectal brachytherapy, thereby improving the participant's quality of life and optimizing treatment time.
The malignant tumor at the thoracic entrance is difficult to be surgically removed, and radiotherapy or radiotherapy based comprehensive treatment is often chosen at the initial diagnosis. However, for patients with recurrence after radiotherapy, there is basically no ideal local treatment.The Radioactive i-125 Seed Implantation (RISI) therapy is characterized by high dose within the tumor target area and low dose to surrounding normal tissues, and its radiation dose rate is low, which theoretically benefits the protection of normal tissues and is more suitable for the salvage treatment of recurrent lesions after radiotherapy.3 d printing template technology is through the advance of the preoperative plan design and optimization, to achieve better avoid endanger organs, template of individualized and human body surface after laminating, registration accuracy, its guide pillar to precise control the direction of the needle, the present data show that in the template with CT guided by solid tumors as well had significantly higher accuracy, as the actual target dose of basic postoperative can reach the design request of the preoperative planning, so the application of 3 d printing template helps to further improve the operation efficiency and safety, also has potential promotion effect to curative effect. The purpose of this study is: (1) Observe the efficacy, toxicity and side effects of 3d-printed template assisted ct-guided RISI in the treatment of recurrent metastatic squamous cell carcinoma of thoracic inlet lymph node after radiotherapy, and evaluate its safety and effectiveness; (2) to explore the relationship between the efficacy, toxicity and side effects of relapsed metastatic squamous cell carcinoma of thoracic inlet lymph node after radiotherapy with different RISI doses;(3)the related influencing factors affecting the effect/toxicity of RISI in the treatment of relapsed lymph node metastatic squamous cell carcinoma at the thoracic inlet after radiotherapy were analyzed.
Patients with recurrence after radiotherapy are often encountered in clinical practice.Patients with recurrence after radiotherapy are less likely to undergo surgery or secondary radiotherapy, and the guidelines recommend only systemic therapy, although the effective rate is relatively low.For patients with local recurrence without distant metastasis, local treatment is still significant.Radioactive I-125 Seed Implantation (RISI) treatment is to I-125 Radioactive nuclide directly inside the implanted tumors, make its rays to continuous destruction of tumor cells, have inside the tumor target high dose, low dose of normal tissue around, and its radiation is low dose rate, in theory, more conducive to the protection of the normal tissue, more suitable for salvage treatment of recurrence after radiotherapy lesions.Some retrospective studies on RISI treatment of NSCLC showed that the local control rate was up to 25%-80%, and there were few reports of toxic and side effects, suggesting that it had good efficiency and safety.Therefore, for patients with recurrent NSCLC after chest radiotherapy, RISI may be considered.And template technology, 3 d printing is a new kind of technology in recent years, can be individualized and human body surface, the guide posts on the the direction of the puncture needle can be accurately controlled, the current data show that in the template with CT guided by solid tumors as well had significantly higher accuracy, as the actual target dose of basic postoperative can reach the design request of the preoperative planning, so the application of 3D printing template helps to further improve the operation efficiency and safety, also has potential promotion effect to curative effect.The purpose of this study was: (1) to observe the efficacy, toxic and side effects of RISI in the treatment of recurrent NSCLC after radiotherapy under the guidance of 3D printing template assisted CT, and to evaluate its safety and effectiveness;(2) to explore the relationship between the efficacy, toxicity and side effects of RISI dose in the treatment of recurrent NSCLC after radiotherapy;(3) analyze the relevant influencing factors affecting the effect/toxicity of RISI in the treatment of recurrent NSCLC after radiotherapy.
Data of 100 patients with locally advanced pancreatic cancer who received stereotactic radiotherapy or ct-guided radioactive 125I seed implantation in the multicenter of the research group from July 2019 to June 2021 were collected, as well as follow-up data.To evaluate the clinical efficacy of stereotactic radiotherapy and ct-guided 125I seed therapy with 3D printing template in pancreatic cancer;In addition, the local control rate and side effects of ct-guided radioactive 125I particles in the treatment of pancreatic cancer lesions were explored, and the efficacy and safety of different doses of stereotactic radiotherapy were determined.
