INTRODUCTION: Radiotherapy is essential for achieving and maintaining local control in head and neck rhabdomyosarcoma (HNRMS) patients. However, radiotherapy may cause outgrowth disturbances of facial bone and soft tissue, resulting in facial asymmetry. The aim of this study was to develop a method to visualize and measure facial asymmetry in HNRMS survivors using three-dimensional (3D) imaging techniques. METHODS: Facial deformity was evaluated in a multidisciplinary clinical assessment of 75 HNRMS survivors, treated with external beam radiotherapy (EBRT, n = 26) or Ablative surgery, MOulage brachytherapy, and REconstruction (AMORE, n = 49)...

Dural prostate metastases (DPM) are a rare manifestation of metastatic prostate cancer seen in approximately one to six percent of cases. Presenting symptoms may include signs of elevated intracranial pressure, headache, altered mental status, or cranial nerve palsies. Hearing loss, sensory changes, dysarthria, and dysphagia are rare symptoms in DPM that were present in our patient. We present a case of a 58-year-old male with a known diagnosis of adenocarcinoma of the prostate presenting with symptoms of acute exacerbation of chronic obstructive pulmonary disease (COPD), sub-acute right-sided hearing loss, and right-sided facial paralysis...

BACKGROUND: Recent studies have shown a decrease in the overall use of radiation therapy in the treatment of prostate cancer over the past several decades, as well as a more conservative overall treatment approach. We aim to determine whether this trend continued from 2004 to 2013, and to determine whether there were changes in utilization for various types of radiation. METHODS: We conducted this retrospective study using the National Cancer Database. We identified 706 877 patients with sufficient treatment information diagnosed with stage IIA prostate cancer between 2004 and 2013...

The purpose of this case study is to describe a dosimetric delivery of radiation to a superficial disease process involving the skin and bone of the distal finger. A 76-year-old male patient presented with a subungual squamous cell carcinoma (SCC) of the left distal index finger with bony involvement. The patient refused conventional surgical treatment but agreed to external beam radiation therapy (EBRT). There is a gap in the current literature describing how to successfully immobilize fingers and which EBRT modality is dosimetrically advantageous in treating them...

The combination external-beam radiotherapy and high-dose-rate brachytherapy is a standard form of treatment for patients with locally advanced uterine cervical cancer. Personalized radiotherapy in cervical cancer requires efficient and accurate dose planning and assessment across these types of treatment. To achieve radiation dose assessment, accurate mapping of the dose distribution from HDR-BT onto EBRT is extremely important. However, few systems can achieve robust dose fusion and determine the accumulated dose distribution during the entire course of treatment...

The entire body of a patient with cancer is exposed to low-dose levels of radiation (mGy) during radiation therapy. The safety and biological impact of such exposure to low-dose radiation on the human body are largely unknown. The fingernail is a highly proliferative tissue, and its growth can be monitored during radiation treatment to analyze early effects of low-dose radiation. The fingernails of 30 patients who received external beam radiotherapy (EBRT) were used in this study to investigate the change in nail growth during fractionated radiotherapy...

BACKGROUND AND PURPOSE: Structure-based deformable image registration (DIR) can be used to calculate accumulated brachytherapy (BT) and external-beam radiation therapy (EBRT) dose-volume histogram (DVH) parameters in cervical cancer. Since direct parameter addition does not take dose non-uniformity into account, the added value of DIR over addition methods was investigated for bladder and rectum. MATERIALS AND METHODS: For twelve patients (EBRT: 46Gy, EBRT+BT: D90 85-90GyEQD2 in equivalent dose in 2Gy fractions) the EBRT planning CT and BT planning MRI were registered using DIR...

New treatments based on combinations of standard therapeutic modalities and immunotherapy are of potential use, but require a profound understanding of immune modulatory properties of standard therapies. Here, the impact of standard (chemo)radiotherapy on the immune system of cervical cancer patients was evaluated. Thirty patients with cervical cancer were treated with external beam radiation therapy (EBRT), using conventional three-dimensional or intensity modulated radiation therapy without constraints for bone marrow sparing...
