To describe the development of a virtual reality (VR) treatment for phantom limb pain (PLP) and sensations provide feasibility data from testing in population veterans.Fourteen participants completed baseline visit evaluating their amputation, PLP, sensations. Subsequently, VR modeled after mirror therapy navigating environment with bicycle pedaler motion sensor to pair cadence avatar. The avatar enabled visualization participant's intact motion, hypothesized mechanism...
Hepatocellular carcinoma (HCC) is aggressive primary malignancy of the liver that most commonly presents late in disease course. As a result, majority patients are not candidates for curative therapies. Locoregional therapies including Yttrium-90 (Y-90) radioembolization play an important role management vast with HCC.Patients unnresectable HCC (n=17) treated Y-90 from 2005 to 2014 were evaluated retrospectively. Data was abstracted medical records patient charts, laboratory data, and...
Total body irradiation (TBI) is a specialized radiotherapy technique. It frequently used as component of treatment plans involving hematopoietic stem cell transplant for variety disorders, most commonly hematologic malignancies. A delivery techniques, doses, and fractionation schemes can be utilized. collaborative effort the American College Radiology Society Radiation Oncology has produced practice guideline TBI. The defines qualifications responsibilities involved personnel, including...
The objective of this study was to validate a dose-point kernel convolution technique that provides three-dimensional (3D) distribution absorbed dose from 3D the radionuclide 131I. A for penetrating radiations calculated by Monte Carlo simulation and cast in rectangular matrix. This matrix convolved with activity map furnished quantitative single-photon-emission computed tomography (SPECT) provide dose. calculation performed using fast Fourier transform (FFT) technique, which takes less than...
Proton therapy is a promising but controversial treatment in the management of prostate cancer. Despite its dosimetric advantages when compared with photon radiation therapy, increased cost to patients and insurers has raised questions regarding value. Multiple prospective retrospective studies have been published documenting efficacy safety proton for localized cancer requiring adjuvant or salvage pelvic after surgery. The Particle Therapy Co-Operative Group (PTCOG) Genitourinary...
The standard of care for locally advanced non-small-cell lung cancer (NSCLC) is either surgery combined with chemotherapy pre- or postoperatively concurrent and radiotherapy. However, older frail patients may not be candidates due to the high mortality risk are frequently referred radiotherapy alone, which better tolerated but carries a disease recurrence. Recently, immunotherapy immune checkpoint inhibitors (ICIs) induce response rate among positive programmed death ligand 1 (PD-L1)...
Older cancer patients are disproportionally affected by the Coronavirus 19 (COVID-19) pandemic. A higher rate of death among elderly and potential for long-term disability have led to fear contracting virus in these patients. This can, paradoxically, cause delay diagnosis treatment that may lead a poor outcome could been prevented. Thus, physicians should devise policy both supports needs older during treatment, serves help them overcome their so they seek out early. combination telemedicine...
The majority of radiation absorbed dose estimates for radioimmunotherapy (RIT) with I‐131 labeled antibodies have been calculated based on in vivo quantitation activity using the conjugate view approach planar Anger camera images. Scatter and septal penetration events contributed by a small fraction high‐energy photons emitted an energy exceeding 600 keV lead to significant degradation images acquired camera, which blurs uptake sites complicates definition background regions. objective this...
The standard of care for locally advanced rectal cancer is total neoadjuvant therapy followed by surgical resection. Current evidence suggests that selected patients may be able to delay or avoid surgery without affecting survival rates if they achieve a complete clinical response (CCR). However, older who are too frail decline the procedure, local recurrence lead deterioration patient quality life. Thus, clinicians, treatment algorithm which well tolerated and improve CCR in with potential...
Radiotherapy delivery in the definitive management of lower gastrointestinal (LGI) tract malignancies is associated with substantial risk acute and late (GI), genitourinary, dermatologic, hematologic toxicities. Advanced radiation therapy techniques such as proton beam (PBT) offer optimal dosimetric sparing critical organs at risk, achieving a more favorable therapeutic ratio compared photon therapy. The international Particle Therapy Cooperative Group GI Subcommittee conducted systematic...
The standard of care for metastatic disease is systemic therapy. A unique subset patients with limited defined as distant involvement five anatomic sites or less (oligometastases) have a better chance remission improved survival and may benefit from local treatments such surgery stereotactic body radiotherapy (SBRT). However, to prevent further spread disease, treatment chemotherapy, targeted therapy, hormonal therapy be required. Older (70 years old above) physiologically frail younger...
The International Commission on Radiation Units and Measurement (IRCU) 50 has clearly defined treatment volumes in radiation therapy the management of neoplasms. These concepts are applied to field endovascular brachytherapy (EVBT) for prevention postangioplasty restenosis. following definitions proposed: gross target length (GTL) is as narrowed segment artery that requires intervention. Clinical (CTL) intervened or injured length, which could be due angioplasty, stent strut injury,...
Since Roentgen’s discovery of X-ray 130 years ago, radiation has been used to treat various diseases including cancer ( Figures 1,2 ). As much excitement seen in the early days when was found be effective shrinking tumors, it also realized potential severe and late adverse complications from same treatment nearby normal structures.
Abstract While randomized clinical trials have demonstrated the excellent efficacy of sirolimus‐eluting stents (SES) for de novo lesions, optimal treatment SES‐restenosis is not known. Management may include stand‐alone balloon angioplasty, repeat SES implantation, or placement a drug‐eluting stent (DES) with an alternative antiproliferative agent (i.e., paclitaxel‐eluting stent, PES). The appropriate management strategy recurrent restenosis after PES implantation even less clear. We report...
Lung cancer is the leading cause of death in USA and worldwide. Radiation has played a significant role treatment all types stages lung cancer. Despite improvement over past few decades, mortality morbidities for patients remain high. often requires multi-modality approaches. therapy (RT) challenging due to pre-existing morbidity, poor tolerance its location near by critical organs (heart, esophagus, spinal cord). Conventional RT with photon improved, but reached plateau. Particle beam...
