The CyberKnife System also utilizes sophisticated software and advanced imaging to track tumor and patient movement and adjust the beams of high-dose radiation to ensure treatment is delivered with a high degree of accuracy.

Additionally, they believed that with greater accuracy in radiation delivery, the CyberKnife System could provide more effective treatments by minimizing the radiation exposure to healthy surrounding tissue and limit some of the short and long- term side effects that are common with conventional treatments. 3 Benefits of CyberKnife® Treatments Is the CyberKnife Treatment Right for Me? • Pain-free • Non-invasive With the CyberKnife System, there is not a • No anesthesia required one-size-fits-all approach to patient care.

  • Radiation Therapy – a Technicians Overview By: Stephanie Corsi, CVT
    Radiation Therapy – A technicians overview By: Stephanie Corsi, CVT Senior Radiation Oncology nurse, PennVet What is radiation therapy? Radiation therapy uses high-energy radiation or high energy particle (electrons) to kill cancer cells and shrink tumors. How does radiation therapy work? Radiation kills cancer cells by damaging their DNA. Cells that are rapidly dividing, like cancer cells, are more susceptible to radiation. The damage is by a high energy photon ejecting a high energy electron that then reacts with a water molecule to create charged particle, also called free radicals, within the cell that will damage the DNA. Most cells die what is called a “mitotic death”, meaning the cancer cells whose DNA is damaged beyond repair will stop dividing and die. Goal of Radiation: The purpose of radiation is to maximize the likelihood of tumor control while minimizing side-effects to the patient. Radiation may be used alone or in combination with surgery, chemotherapy, or both. “Curative” intent/ definitive therapy: This is given when the prognosis is good. The hope is that treatment will cure a cancer by eliminating a tumor and preventing recurrence. For tumors that are inherently sensitive, relatively small, and localized. Also used to treat residual cancer left behind after surgery, or before surgery to shrink a tumor. Examples: localized lymphomas, certain mast cell tumors, cutaneous squamous cell carcinomas Palliative intent: Not intended to cure, but rather relieve symptoms and reduce suffering. Given when prognosis is poor and quality of life is the primary focus. Used with bulky tumors. Examples: alleviate bone pain associated with osteosarcoma, a tumor pressing on the spine, tumors pressing on the esophagus interfering with breathing/eating, etc.

  • Clinical Outcomes and Prognostic Factors of Cyberknife Stereotactic
    Que et al. BMC Cancer (2016) 16:451 DOI 10.1186/s12885-016-2512-x RESEARCH ARTICLE Open Access Clinical outcomes and prognostic factors of cyberknife stereotactic body radiation therapy for unresectable hepatocellular carcinoma Jenny Que1*, Hsing-Tao Kuo2, Li-Ching Lin1, Kuei-Li Lin1, Chia-Hui Lin1, Yu-Wei Lin1 and Ching-Chieh Yang1 Abstract Background: Stereotactic body radiation therapy (SBRT) has been an emerging non-invasive treatment modality for patients with hepatocellular carcinoma (HCC) when curative treatments cannot be applied. In this study, we report our clinical experience with Cyberknife SBRT for unresectable HCC and evaluate the efficacy and clinical outcomes of this highly sophisticated treatment technology. Methods: Between 2008 and 2012, 115 patients with unresectable HCC treated with Cyberknife SBRT were retrospectively analyzed. Doses ranged from 26 Gy to 40 Gy were given in 3 to 5 fractions for 3 to 5 consecutive days. The cumulative probability of survival was calculated according to the Kaplan-Meier method and compared using log-rank test. Univariate and multivariate analysis were performed using Cox proportional hazard models. Results: The median follow-up was 15.5 months (range, 2-60 months). Based on Response Evaluation and Criteria inSolidTumors(RECIST).Wefoundthat48.7%ofpatients achieved a complete response and 40 % achieved a partial response. Median survival was 15 months (4-25 months). Overall survival (OS) at 1- and 2-years was 63. 5 %(54-71.5 %) and 41.3 % (31.6-50.6 %), respectively, while 1- and 2- years Progression-free Survival (PFS) rates were 42.8 %(33.0-52.2 %) and 38.8 % (29.0-48.4 %).

Giordano6 Received: 19 August 2019 / Accepted: 5 October 2019 © Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Background and objective The ideal delivery of radiation to the surgical cavity of brain metastases (BMs) remains the subject of debate. Risks of local failure (LF) and radiation necrosis (RN) have prompted a reappraisal of the timing and/or modality of this critical component of BM management. IORT delivered at the time of resection for BMs requiring surgery ofers the potential for improved local control (LC) aforded by the elimination of delay in time to initiation of radiation following surgery, decreased uncertainty in target delineation, and the possibility of dose escalation beyond that seen in stereotactic radiosurgery (SRS). This study provides a retrospective analysis with identifcation of potential predictors of outcomes. Methods Retrospective data was collected on patients treated with IORT immediately following surgical resection of BMs at three institutions according to the approval of individual IRBs. All patients were treated with 50kV portable linear accelerator using spherical applicators ranging from 1.5 to 4.0 cm. Statistical analyses were performed using IBM SPSS with endpoints of LC, DBC, incidence of RN, and overall survival (OS) and p < 0.05 considered signifcant. Results 54 patients were treated with IORT with a median age of 64 years.
