Correspondence to: Zhengfei Zhu, MD. Department of Radiation Oncology, Fudan University Shanghai Cancer Center, 270 Dong An Road, Shanghai, 200032 China. Email: [email protected]. Abstract: Significant recent advances have occurred in the use of radiation therapy for locally advanced non-small cell lung cancer (LA-NSCLC). In fact, the past few decades have seen both therapeutic gains and setbacks in the evolution of radiotherapy for LA-NSCLC. The PACIFIC trial has heralded a new era of immunotherapy and has raised important questions for future study, such as the future directions of radiation therapy for LA-NSCLC in the era of immunotherapy. Modern radiotherapy techniques such as three-dimensional (3D) conformal radiotherapy and intensity-modulated radiotherapy (IMRT) provide opportunities for improved target conformity and reduced normal-tissue exposure. However, the low-dose radiation volume brought by IMRT and its effects on the immune system deserve particular attention when combing radiotherapy and immunotherapy. -

Background: To report on our institutional experience using Proton stereotactic body radiation therapy (SBRT) for patients with liver metastases. Methods: All patients with liver metastases treated with Proton SBRT between September 2012 and December 2017 were retrospectively analyzed. Local control (LC) and overall survival (OS) were estimated using the Kaplan-Meier method calculated from the time of completion of Proton SBRT. LC was defined according to Response Evaluation Criteria in Solid Tumors (RECIST) guidelines (version 1.1). -

Featured Application: Radiation therapy treatment planning. Abstract: Radiation therapy (RT) is a constantly evolving therapeutic technique; improvements are continuously being introduced for both methodological and practical aspects. Among the features that have undergone a huge evolution in recent decades, dose calculation algorithms are still rapidly changing. This process is propelled by the awareness that the agreement between the delivered and calculated doses is of paramount relevance in RT, since it could largely affect clinical outcomes. The Citation: De Martino, F.; Clemente, aim of this work is to provide an overall picture of the main dose calculation algorithms currently S.; Graeff, C.; Palma, G.; Cella, L. used in RT, summarizing their underlying physical models and mathematical bases, and highlighting Dose Calculation Algorithms for their strengths and weaknesses, referring to the most recent studies on algorithm comparisons. External Radiation Therapy: An This handy guide is meant to provide a clear and concise overview of the topic, which will prove Overview for Practitioners. -
Clinical Policy: Proton and Neutron Beam Therapies Reference Number: CP.MP.70 Coding Implications Last Review Date: 11/20 Revision Log
Clinical Policy: Proton and Neutron Beam Therapies Reference Number: CP.MP.70 Coding Implications Last Review Date: 11/20 Revision Log See Important Reminder at the end of this policy for important regulatory and legal information. Description Proton beam therapy (PBT) is a form of external beam radiation therapy (EBRT) that utilizes protons (positively charged subatomic particles) to precisely target a specific tissue mass. Proton beams can penetrate deep into tissues to reach tumors, while delivering less radiation to surrounding tissues. This may make PBT more effective for inoperable tumors, or for those areas in which damage to healthy tissue would pose an unacceptable risk. Neutron beam therapy (NBT) is a less widely available form of EBRT that utilizes neutrons. Its clinical use is very limited due to difficulties in the delivery of this treatment modality. Policy/Criteria I. It is the policy of health plans affiliated with Centene Corporation® that proton beam therapy is medically necessary for the following indications: A. Ocular tumors with no distant metastasis. Fiducial markers (tantalum clips) are permitted to allow eye and tumor position verification; or B. Primary or metastatic tumors of the spine where the spinal cord tolerance may be exceeded with conventional treatment or where the spinal cord has previously been irradiated; or C. Tumors that approach or are located at the base of the skull, including but not limited to: chordoma or chondrosarcoma; or D. Primary hepatocellular cancer treated in a hypofractionated regimen; or E. Primary or benign solid tumors in members/enrollees ≤ 18 years old; or F. Genetic syndromes making total volume of radiation minimization crucial such as but not limited to NF-1 patients and retinoblastoma; or G. -

The clinical benefit of proton therapy is that it allows to treat tumors more precisely. As a result, proton radiotherapy induces less toxicity to healthy tissue near the tumor site. Despite the experience in the clinical use of protons, the response of cells to proton radiation, the radiobiology, is less understood. In this review, we describe the current knowledge about proton radiobiology. Abstract: Clinical use of proton radiation has massively increased over the past years. The main reason for this is the beneficial depth-dose distribution of protons that allows to reduce toxicity to normal tissues surrounding the tumor. Despite the experience in the clinical use of protons, the radiobiology after proton irradiation compared to photon irradiation remains to be completely elucidated. Proton radiation may lead to differential damages and activation of biological processes. -
