Ocular proton therapy (OPT) is considered the elective treatment for different kinds of highly malignant intraocular tumor. Uveal, iris and conjunctival melanomas, ocular hemangioma and retinoblastomas are amongst the lesions typically treated with OPT, particularly if target thickness prevents the applicability of other treatment modalities such as brachytherapy [1 –4]. A remarkable local control rate (well over 90%) was reported over the years by several institutions with over 28.000 patients treated worldwide [1,5,6], even though concomitant counter-effects, such as radiation induced damage to the lacrimal gland, ...

Authors: Podder TK, Fredman ET, Ellis RJ Abstract Major categories of radiotherapy (RT) for prostate cancer (CaP) treatment are: (1) external beam RT (EBRT), and (2) brachytherapy (BT). EBRT are performed using different techniques like three-dimensional conformal RT (3D-CRT), intensity modulated RT (IMRT), volumetric modulated arc therapy (VMAT), and stereotactic body radiation therapy (SBRT), stereotactic radiosurgery (SRS) and intensity modulated proton therapy (IMPT), etc., using a variety of radiation delivery machines, such as a linear accelerator (Linac), Cyberknife robotic system, Gamma knife, Tomotherapy a...

Eye-preservation using brachytherapy (BT) and proton therapy (PT) are commonly used as primary treatments for uveal melanomas (UM). Choice of modality generally depends on local availability rather than direct assessment of the two techniques. We conducted a comparative dose planning study, estimating biologically effective doses (BED) to the tumour, macula and optic nerve head (ONH).

Age-related macular degeneration (AMD) is the leading cause of blindness in aging adults and affects millions of patients in the U.S. and even more worldwide. Existing treatments of the most devastating neovascular form of AMD involve monthly injections into the eye(s) of patients, who typically are elderly. These injections are costly and burdensome, requiring periodic intraocular injections for drug delivery. Radiation has been used to treat AMD: 6 MV external-beam radiation irradiation, proton therapy, and most recently stereotactic x-rays and beta applicators.

In vivo dosimetry (IVD) is an important component of a comprehensive quality assurance program as a final check at the point of radiotherapy delivery; IVD can measure target doses, prevent dose delivery errors, and enhance the standard of patient care. IVD has been widely used in conventional external beam radiotherapy [1] and brachytherapy [2]. In external beam radiotherapy, IVD is mostly used for entrance dose measurement because it is easy to place a detector on the skin of the patient. For photon beam radiotherapy, transmission measurements using an electronic portal imaging device (EPID) are also gaining interest for IVD [3].

This article aims to review the complex RMS classification system and treatment of BP RMS, with a focus on developing aspects of treat ment.Recent FindingsRecent advancements in technology are responsible for most of the progress in RMS treatment. PET-CT scanning has been shown to be superior to conventional metastatic workup. The use of proton beam therapy and brachytherapy to reduce the side effects of radiation is also showing promise.SummaryAll cooperative oncology groups agree on surgical biopsy for diagnosis and staging of BP RMS. Patients are then grouped and risk classified before receiving chemotherapy. Regardless...

Authors: Kortmann RD, Seidel C, Müller K, Hirsch FW Abstract Attainment of local control is a cornerstone in the management of brain tumors in children. Treatment of progressive low-grade and all high-grade gliomas traditionally includes resection followed by fractionated radiotherapy (FRT) or FRT alone in neoplasms not amenable to surgical removal. While in younger children chemotherapy is typically used as a first-line non-surgical management option, FRT in such patients remains the standard of salvage therapy. Recent improvements in techniques for radiation treatment planning and delivery allow conformal an...

Abstract BackgroundRhabdomyosarcoma (RMS) occurring at nonparameningeal head and neck (NPM‐HN) sites carries a better prognosis than parameningeal RMS and some other sites. We analyzed the treatments administered and results obtained in patients with localized NPM‐HN RMS, included in the protocols coordinated by the Italian Soft Tissue Sarcoma Committee (STSC), in an effort to identify prognostic factors that could facilitate the tailoring of treatment. MethodsSixty‐six patients up to 18 years of age with previously untreated, localized NPM‐HN RMS were prospectively registered in three consecutive protocols: RMS79,...
