Study to Detect Changes in Urinary and Gut Microbiome During Androgen Deprivation Therapy and Radiation Therapy in Patients With Prostate Cancer
This study collects urine and stool samples to determine the ability to identify changes in the microbiome (bacteria, fungi, and viruses that live in the gut and urine) of patients with prostate cancer during androgen deprivation therapy and radiation therapy. Radiation therapy has the potential to harm the genitourinary area …
I-125 Seeds Implantation in the Treatment of Recurrent Lung Cancer After Radiotherapy
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 …
Safety and Efficacy of SBRT in the Reirradiation for Ultra-central Thoracic Malignant Tumors
The reirradiation of thoracic tumor is difficult. The possibility of surgery or re course radiotherapy is very small. In the NCCN guideline, only systemic treatment is recommended. However, the effective rate of systemic treatment is low. SBRT has the characteristics of high dose in tumor target area and low dose …
Prospective Neurobehavioral Functions in Newly-diagnosed Patients With Primary CNS Lymphoma Treated With Hyperfractionated Conformal Whole-brain Radiation Therapy Plus Simultaneous Integrated Boost
Primary central nervous system lymphoma (PCNSL) is an uncommon disease. Conventional treatment has consisted of either whole-brain radiation therapy (WBRT) or methotrexate (MTX)-based combined modality therapy integrating chemotherapy with cranial irradiation in a sandwiched manner. No matter whether the dosage of MTX is high or conventional, combining chemotherapy with WBRT …
Comparison of Efficacy in SBRT of Large HCC With or Without TACE
The study aims to compare efficacy and adverse reactions of large hepatocellular carcinoma participants (5-10cm) who receive stereotactic body radiation therapy with or without transcatheter arterial chemoembolization.The investigators will optimize the combined treatment schedule of SBRT for hepatocellular carcinoma participants by comparing overall survival rates, progression-free survival rates and local …
The Predictive Value of Coexisting TMPRSS2-ERG Gene Fusion and PTEN Deletion in Prostate Cancer Patients With Biochemical Failure Status Post Salvage or Radical Radiation Therapy
The objective of the study is to evaluate the predictive value of TMPRSS2-ERG gene fusion and PTEN in patients with high risk prostate cancer treated with first line LHRH agonist after biochemical failure.
Lymphedema Evaluation After Adjuvant Hypofractionated Radiotherapy for 1-2 Macrometastatic Sentinel Lymph Nodes
In this observational prospective studi patients with invasive breast cancer no more than 5 cm and clinically node negative, scheduled for conservative surgery and Sentinel Node Biopsy (SNB), are enrolled in the protocol if they have 1-2 sentinel lymphnodes (SLNs) with macrometastases. SLN status will be checked on definitive sections.
Observational Study on Extreme Hypofractionation for Localized Prostate Cancer
Radiotherapy (RT) is an established treatment option for localized prostate cancer (PCa), with cure rates similar to those of radical prostatectomy. In the last decade, conventionally fractionated RT (1.8-2.0 Gy per fraction to 78-80 Gy) has been replaced by moderately hypofractionated RT (2.3-3.65 Gy per fraction to 56-70 Gy). The …
Prospective Observational Study on Outcome of High-precision Hypo-fractionated Radiotherapy in Metastatic Breast Cancer (PRECISE-M)
This study is a prospective observational study on outcomes of high precision hypo-fractionated radiotherapy in breast cancer with distant metastasis.
High Dose Rate (HDR) Brachytherapy Salvage After Prostatectomy
The goal of this observational study is to learn about the long-term effects of HDR Brachytherapy in men with isolated local relapses after radical prostatectomy. The main question it aims to answer is: Does HDR Brachytherapy increase control rates and decreases complications compared with conventional External Irradiation? Participants will be …
