Filter by:Ablation of atrial fibrillation (AFib) has been recommended as a therapeutic option when rhythm maintenance strategy is sought. One of the main objectives of an AFib ablation procedure is electrical isolation of the pulmonary veins, which have been identified as common triggering sites of the arrhythmia. The pathophysiology of AFib is not fully elucidated. Inflammation seems to play an important role in the initiation and maintenance of AFib. Previous studies have shown that inflammatory markers reactivity (eg, C-reactive protein [CRP] complex levels, elevation of white blood cells) are increased in patients who develop AFib. Similarly, recurrence of AFib within the first few weeks after ablation procedure seems to be mediated by an inflammatory process triggered by the ablation per se as implied by increased early CRP levels in AFib ablation patients. On the other hand, AFib can further induce and maintain a cascade of inflammatory events leading to electrical and structural atrial remodeling which leads to higher incidence of Afib development. Many trials have investigated the role of anti-inflammatory agents in preventing post-ablation AFib, using various treatment regimens such as corticosteroid therapy, antiarrhythmic medications like amiodarone, intravenous magnesium, atorvastatin, and colchicine. Previous studies have shown that colchicine can lead to decreased recurrence of post-ablation AFib with a beneficial impact in self-perceived quality of life of the patients. There is limited knowledge regarding the impact of colchicine duration and dosing on post-ablation Afib recurrence and the self-perceived quality of life. The information obtained from this study will ultimately guide future clinical practice to ensure safer outcomes.
The study aims to obtain a local control rate in patients with lateral pelvic relapses of gynecologycal cancers previously irradiated. High LET (Linear Energy Transfer) particles as carbon ions can guarantee a biologic advantage compared to photons in radioresistant neoplasms, given to their higher biological efficacy (RBE).
STereotactic sAlvage Radiotherapy for macroscopic prostate bed Recurrence after prostatectomy (STARR trial) is a prospective observational study aimed to assess outcome after Stereotactic salvage radiotherapy (SSRT) for macroscopic prostate bed recurrence after radical prostatectomy.
This phase II trial tests whether loncastuximab tesirine works to shrink tumors in patients with B-cell malignancies that have come back (relapsed) or does not respond to treatment (refractory). Loncastuximab tesirine is a monoclonal antibody, called loncastuximab, linked to a chemotherapy drug, called tesirine. Loncastuximab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD19 receptors, and delivers tesirine to kill them.
To evaluate local tumor progression rate at 12 months after no-touch percutaneous radiofrequency ablation using combined energy delivery mode and triple cooled electrodes
Hyperthermic intrathoracic chemotherapy (HITOC) offers an additional treatment option for malignant pleural tumors after surgical cytoreduction. Especially it is used to further improve local tumor control in thymic malignancies with pleural spread, who underwent multimodality therapy including surgical resection. A phase II clinical study was conducted to explore the efficacy and safety of surgery followed by HITOC (POD1: DOX, POD2: cisplatin) for thymic epithelial tumors with pleural spread or recurrence.
This study dynamically monitored the prognosis of stage I-IV colorectal cancer patients who could receive radical surgical resection by detecting the levels of polygene methylation in plasma samples from patients with colorectal cancer. In patients with colorectal cancer feasible radical surgery, plasma ctDNA methylation detection was performed before and after surgical treatment and during regular follow-up to explore the predictive effect of plasma ctDNA methylation status at different time points on postoperative recurrence. To explore whether postoperative dynamic monitoring of plasma ctDNA methylation can be used for adjuvant chemotherapy efficacy evaluation and whether it can indicate tumor recurrence and metastasis earlier than imaging examination.
This study intends to evaluate the efficacy and safety of microwave ablation combined lenvatinib simultaneously for recurrent HCC
The overall goals of this proposal are to determine the genetic architecture of recurrent pregnancy loss (RPL) and to discover genomic predictors of RPL.
Rationale Ovarian cancer is the 3rd most common gynecologic malignancy in Korea. The standard treatment is tumor debulking surgery with or without adjuvant chemotherapy. However, with a recurrence rate of 80%, the treatment results are the worst among gynecological cancers. The use of target and immune agents have demonstrated to improve survival. However, long-term maintenance of systemic therapy is often difficult because recurrent tumors do not respond uniformly to systemic therapy. In the 1980~1990s, whole abdomen irradiation had been tried and faded out owing to many side effects with the introduction of taxane. Efforts have been made to find the role of salvage radiation therapy (RT) in recurrent ovarian cancer. Involved field radiotherapy (IFRT) emerged to cover the gross tumor plus regional microscopic disease in addition to salvage chemotherapy. It showed high local control, provided chemotherapy holiday in selected cases, but did not prevent out-field progression. Stereotactic ABlative Radiotherapy (SABR) is the latest treatment using an intensity modulated technique to increase the fractional dose, reduces the number of treatments, and destroys the tumor with high accuracy. SABR-COMET study, a representative clinical study, showed a significant increase in overall survival in solid cancers. Objectives The primary objective; to evaluate whether the addition of SABR to standard salvage treatment significantly improves 3-year overall survival (OS) in patients with recurrent ovarian cancer. The secondary objectives; - to check whether it significantly affects quality of life (Health-related QoL), patient-reported outcome (PRO) - to develop an deep learning-based predictive model for the treatment response of ovarian cancer subjects using radiomic and genomic analysis. Study design Arm 1; Standard salvage therapy Subjects will continue to receive current salvage treatment suitable for subjects at the discretion of their doctor, considering the location and size of recurrence, and the patient's comorbidities. Arm 2; Standard salvage therapy+ SABR Subjects receive SABR for lesions found in imaging studies. Before or After SABR, standard salvage treatment continues as planned at the discretion of the doctor. Stratification factors 1.
