Stereotactic body radiation therapy (SBRT) for stage I non-small cell lung cancer (NSCLC) is considered standard of care in the medically inoperable patient population. Multiple methods SBRT delivery exist including fiducial-based tumor tracking, which allows smaller treatment margins and avoidance immobilization devices. We explore long-term clinical outcomes this novel method.In single institutional retrospective review, we detail pathologically confirmed NSCLC. Patients were treated with...
Local treatment options for patients with in-field non-small cell lung cancer (NSCLC) recurrence following conventionally fractionated external beam radiation therapy (CF-EBRT) are limited. Stereotactic body (SBRT) is a promising modality to achieve reasonable local control, although toxicity remains concern.Patients previously treated high-dose CF-EBRT (≥59.4 Gy, ≤3 Gy/fraction) non-metastatic NSCLC who underwent salvage SBRT localized ultra-central were included in this analysis....
Background: Clinical data suggest that stereotactic body radiation therapy (SBRT) provides similar clinical outcomes as other modalities for prostate cancer. However, reporting on the safety of SBRT after TURP is limited. Herein, we report our experience using to deliver hypofractionated radiotherapy in patients with a history including physician-reported toxicities and patient-reported quality life. Methods: Forty-seven treated from 2007 2016 at Georgetown University Hospital localized...
Our previous work on early PSA kinetics following prostate stereotactic body radiation therapy (SBRT) demonstrated that an initial rapid and then slow decline may result in very low nadirs. This retrospective study sought to evaluate the nadir 5 years SBRT for low- intermediate-risk cancer (PCa).65 80 PCa patients were treated definitively with 35-37.5 Gy fractions at Georgetown University Hospital between January 2008 October 2011. Patients who received androgen deprivation excluded from...
Few definitive treatment options exist for elderly patients diagnosed with early stage breast cancer who are medically inoperable or refuse surgery. Historical data suggest very poor local control hormone therapy alone. We examined the dosimetric feasibility of hypofractionated radiation using stereotactic ablative radiotherapy (SABR) and proton beam (PBT) as a means cancer.Fifteen biopsy-proven clinically visible tumor on preoperative computed tomography scans were identified. Gross volumes...
Background: Patients with a high pretreatment IPSS may have higher rates of late urinary morbidity after radiation therapy for prostate cancer (1). Stereotactic body (SBRT) delivers fewer high-dose fractions radiation, which be radiobiologically favorable to the conventional low-dose external beam fractions. The toxicity associated SBRT, however, remains unclear in patients We report our experience using SBRT localized ≥ 15. Methods: Localized pre-treatment 15 treated at Georgetown...
Purpose: Stereotactic body radiation therapy (SBRT) has been established as a safe and effective treatment for prostate cancer. SBRT requires high accuracy to reduce margins. Metal hip prostheses create artifacts that distort pelvic imaging potentially decrease the of target/organ at risk (OAR) identification dose calculations. Data on safety efficacy after replacement is limited. This single-institution study sought evaluate local control following cancer in men with replacements. Methods:...
123 Background: Our previous work on early PSA kinetics following prostate SBRT showed that an initial rapid and then slow decline may result in very low nadirs. This retrospective study sought to evaluate the nadir 5 years for intermediate risk cancer (PCa). Methods: 65 80 PCa patients were treated definitively with at Georgetown University Hospital between January 2008 October 2011. All 35-37.5 Gy fractions delivered via CyberKnife Radiosurgical System. Patients who received androgen...
91 Background: Patients with a history of procedures for BPH experience worse urinary toxicity following interstitial brachytherapy localized prostate cancer. This retrospective study sought to evaluate the rates SBRT in men BPH. Methods: Localized cancer patients, treated from August 2009 February 2015 and minimum follow up 2 years, at least 1 procedure associated prostatic defect identified on treatment planning MRI were evaluated. Radiotherapy was delivered 5 fractions dose 35 or 36.25 Gy...
S735ESTRO 37large studies showing benefit of PMRT.PMRT is well known for having a negative impact on IBR, but several papers seem to invalidate these data.This study reports the rate breast RF after PMRT at our Department, comparing tissue expander (TE) with permanent implant (PI). Material and MethodsPts that underwent mastectomy immediate TE/PI reconstruction followed by between June 1997 December 2011 were retrospectively evaluated.RF failure was defined as replacement or loss conversion...
64 Background: Prostate Cancer (PCa) related anxiety varies widely based on management option. SBRT offers a safe and effective treatment for localized PCa. However, there is paucity of data regarding PCa specific following its relationship with PSA kinetics. In this report we present the results mail-in survey conducted amongst participants our prospective institutional quality life (QOL) trial identify sociodemographic disease predictors anxiety. Methods: Patients treated at single...
Purpose or ObjectiveThe Eastern Cooperative Oncology Group performance score (ECOG-PS) is widely used in clinical routine to quantify patients' general condition.We evaluated ECOG-PS before, after and its alteration the course of chemoradiotherapy (CRT) patients with stage III nonsmall cell lung cancer (NSCLC). Material MethodsThe data ninety-eight NSCLC UICC 7 th edition IIIA/B status ECOG 0-1 before treatment was evaluated.ECOG-PS treatment, on first medical aftercare difference between,...
