Cellular Damage in the Target and Out-of-Field Peripheral Organs during VMAT SBRT Prostate Radiotherapy: An In Vitro Phantom-Based Study

Project description:New developments show that patients with prostate cancer can benefit from radiotherapy deliv-ered with a hypo-fractionated regimen. The aim of our study was to investigate the effect of hy-po-fractionated stereotactic body radiation therapy (SBRT) of prostate cancer on out-of-field organs. We used a humanoid phantom to irradiate prostate cells in conditions similar to patient therapy, using SBRT planning. Our results show that radiation doses in the location of the intes-tine and lung resulted in significantly higher radiation doses than the further locations. We observed a high radiotoxic effect in the cells irradiated in the prostate, and a small increase in DNA damage and cell killing in the intestine location. Gene expression analysis revealed significant enrichment of the biological processes related to the radiation response in the prostate. In the lung and thyroid, the enrichment of several gene groups was revealed, however the processes were not clearly related to the response to radiation. Our study provides extensive data on out-of-field safety of prostate SBRT.

Modulation of the human pancreatic ductal adenocarcinoma immune microenvironment by stereotactic body radiotherapy

Project description:Purpose: Stereotactic body radiotherapy (SBRT) is an emerging treatment modality for pancreatic ductal adenocarcinoma (PDAC) that can effectively prime cytotoxic T cells by inducing immunogenic tumor cell death in preclinical models. SBRT effects on human PDAC have yet to be thoroughly investigated, therefore, this study aimed to characterize immunomodulation in the human PDAC tumor microenvironment following therapy. Experimental Design: Tumor samples were obtained from patients with resectable PDAC. Radiotherapy was delivered a median of seven days prior to surgical resection, and sections were analyzed by multiplex IHC (mIHC), RNA-Seq, and T cell receptor sequencing (TCR-Seq). Results: Analysis of SBRT-treated tumor tissue indicated reduced tumor cell density and increased immunogenic cell death relative to untreated controls. Radiotherapy promoted collagen deposition, however, vasculature was unaffected and spatial analyses lacked evidence of T cell sequestration. Conversely, SBRT resulted in fewer tertiary lymphoid structures and failed to lessen or reprogram abundant immune suppressor populations. Higher percentages of PD-1+ T cells were observed following SBRT, and a subset of tumors displayed more clonal T cell repertoires. Conclusions: These findings suggest that SBRT augmentation of antitumor immunogenicity may be dampened by an overabundance of refractory immunosuppressive populations, and support the continued development of SBRT/immunotherapy combination for human PDAC.

RNA Sequencing of Intratumoral Immune Populations in Pancreatic Ductal Adenocarcinoma Following Radiotherapy and Interleukin 12 Treatment

Project description:We report differential gene expression in inflammatory monocyte (IM), tumor-associated macrophage (TAM), and CD8 T cell populations following stereotactic body radiation (SBRT), intratumoral interleukin 12 microsphere (IL-12 MS) delivery, and SBRT/IL-12 MS combination. Immune cell populations were sorted from orthotopic murine pancreatic ductal adenocarcinoma (PDA) tumors prior to RNA sequencing.

Stereotactic Body Radiation Therapy (SBRT) in Liver Metastasis (COLD 3)

Project description:This study is designed to see whether stereotactic body radiation therapy (SBRT) can reduce tumour size, slow progression of the disease, prolong life and improve quality of life. SBRT is concentrated focused radiation therapy delivered very precisely to the liver tumour. Presently, the treatment for unresectable liver metastases from colorectal cancer is most often chemotherapy or novel targeted therapy. These treatments may improve survival, but not control the metastases permanently; so new treatments are needed to control metastases. It is hoped that knowledge obtained from this study will improve our ability to treat patients with liver tumours that cannot be treated with surgery and other methods, and that SBRT may prove to be a treatment that can lead to long-term and permanent control of liver tumours for some patients.

Multiple Primary Lung Cancers: Treatment Outcomes After Stereotactic Body Radiotherapy (SBRT).

Project description:Purpose/objectivesPatients with lung cancer sometimes present with multiple primary lung cancers (MPLCs), either simultaneously (synchronous) or after treatment of an initial lesion (metachronous). Although open surgery remains a treatment mainstay for patients with stage I-II non-small-cell lung cancer (NSCLC), stereotactic body radiation therapy (SBRT) is an acceptable alternative for patients who are medically unfit for or who refuse surgery. In this study, we retrospectively examine the outcome among patients with early-stage MPLCs treated at our institution with SBRT.Materials/methodsPatients at our institution receiving SBRT for MPLC between June 2011 and March 2020 were reviewed retrospectively. Prior to undergoing definitive SBRT, the imaging, and pathology for every patient were reviewed in a multi-disciplinary thoracic/pulmonary tumor board. Dose and fractionation varied with the most common prescriptions being 50 Gy/5 fractions, 56 Gy/4 fractions, and 55 Gy/5 fractions.ResultsA total of 38 patients with a total of 80 MPLCs were treated, among which 68 were T1 lesions and 12 were T2 lesions. Median follow-up was 25.9 months, with local control (LC) rates calculated per lesion to be 98.6%, 93.3%, and 88.2% at one, two, and three years. Median overall survival (OS) was 43.5 months; 83.6%, 67.8%, and 52.3% at one, two, and three years, respectively. Sixty-two of the 80 (77.5%) treated lesions were not associated with any subsequent acute or late toxicity. The 18 (22.5%) lesions associated with toxicity included nine acute and nine late events. All toxicity was either grade 1 (13 of 18) or grade 2 (five of 18).ConclusionsSBRT for early-stage MPLC achieves high control rates with limited toxicity. MPLC patients deemed unfit for open surgical management should be considered for definitive SBRT.

Phase II Study of Toripalimab Plus Stereotactic Body Radiotherapy in Colorectal Cancer Patients With Oligometastasis

Project description:Metastatic colorectal cancer is one of the common malignant tumors and the overall prognosis is poor. The introduction of immune-checkpoint inhibition (ICI) has led to a paradigm shift in the treatment of patients with metastatic cancer. Stereotactic body radiation therapy (SBRT) delivers a large dose of radiation to the tumor target with high precision while sparing irradiation of the surrounding normal tissues. It is suggested that SBRT could be the most appropriate radiotherapy modality to be combined with immunotherapy since it induces the expression of a series of cytokines and new tumour-associated antigens (TAAs) and is more likely to cause intense immune response and exert an abscopal effect than conventional radiotherapy. Thus, this study is to explore the use of SBRT in combination with ICI in colorectal cancer patients with oligometastasis, in order to get better local and systemic tumor control and improve progress-free survival (PFS).

Stereotactic Body Radiotherapy in Patients With Rare Oligometastatic Cancers (OligoRARE)

Project description:This is a randomized open-label multicentre Phase III superiority study of the effect of adding SBRT to the standard of care treatment on overall survival in patients with rare oligometastatic cancers. Patients will be randomized in a 1:1 ratio between current standard of care treatment vs. standard of care treatment + SBRT to all sites of known metastatic disease. The primary objective of this trial is to assess if the addition of stereotactic body radiotherapy (SBRT) to standard of care treatment improves overall survival (OS) as compared to standard of care treatment alone in patients with rare oligometastatic cancers.
