Radiotherapy and surgery are the two main pillars of the locoregional treatment of cancer. The risk of second malignancy is better evaluated and constitutes a major issue regarding radioprotection of the patients. Among malignant disease observed in the surviving irradiated patients, the occurrence of sarcoma is a rare event but associated with a poor outcome since the 5 year overall survival is estimated at 10 to 35 %. The SARI protocol, written in 2011, included 120 patients and 240 controlled patients, irradiated in the same conditions but without sarcoma observed during the follow up...

BACKGROUND: Proton beam radiotherapy (PBT) is frequently shown to be dosimetrically superior to photon radiotherapy (RT), though supporting data for clinical benefit are severely limited. Because of the potential for toxicity reduction in gastrointestinal (GI) malignancies, we systematically reviewed the literature on clinical outcomes (survival/toxicity) of PBT. METHODS: A systematic search of PubMed, EMBASE, abstracts from meetings of the American Society for Radiation Oncology, Particle Therapy Co-Operative Group, and American Society of Clinical Oncology was conducted for publications from 2000-2015...

PURPOSE: Combined modality therapy is a mainstay option for thoracic malignancies and head and neck cancers. The integration of different strategies is based on the multidisciplinary approach of modern clinical oncology. Radiation oncologists have to be educated, trained, and updated to provide state-of-the-art care to cancer patients and thus educational meetings are crucial. METHODS: The Italian Association of Radiation Oncology Young Members Working Group (AIRO Giovani) organized its 8th national meeting, focused on combination therapy in lung, esophageal, and head and neck cancer (with a specific focus on larynx-preservation strategies for larynx/hypopharynx tumors), involving young professionals working in Italy...

IMPORTANCE: Since their discovery in the 1970s, taxanes have maintained widespread clinical use in solid tumors, including squamous cell carcinoma of the head and neck (SCCHN), but SCCHN remains a difficult malignancy to treat, often requiring a multidisciplinary approach involving surgery, radiotherapy, and chemotherapy. Taxanes have been heavily studied in the treatment of SCCHN, and their use is currently in the setting of induction chemotherapy with the TPF (docetaxel, FU, cisplatin) regimen for locally advanced SCCHN, as well as in the concurrent therapy setting...

Radiation and chemotherapy are the main pillars of the current multimodal treatment concept for cancer patients. However, tumor recurrences and resistances still hamper treatment success regardless of advances in radiation beam application, particle radiotherapy, and optimized chemotherapeutics. To specifically intervene at key recurrence- and resistance-promoting molecular processes, the development of potent and specific molecular-targeted agents is demanded for an efficient, safe, and simultaneous integration into current standard of care regimens...

BACKGROUND: In locally advanced pelvic malignancies, there is often involvement of urological organs, necessitating resection and reconstruction, which can be associated with significant complications. METHODS: We retrospectively reviewed 20 patients undergoing urological reconstructions during pelvic oncological surgeries from January 2004 to December 2013. All patients had imaging-proven involvement of at least one urological organ preoperatively. Primary outcome was urological complication rate...

PURPOSE: We focused the attention on radiation therapy practices about the gynecological malignancies in Piedmont, Liguria, and Valle d'Aosta to know the current treatment practice and to improve the quality of care. MATERIAL AND METHODS: We proposed a cognitive survey to evaluate the standard practice patterns for gynecological cancer management, adopted from 2012 to 2014 by radiotherapy (RT) centers with a large amount of gynecological cancer cases. There were three topics: 1...

Vulvar neoplasms represent four percent of all gynecological cancers. While most cases of vulvar neoplasms are benign, two percent of patients present with malignant disease. We present the case of a 37-year-old premenopausal female who presented to an outside institution with a lump in her left vulva, which had progressively enlarged to the size of an egg. A wide local excision of the left vulva was performed, and the pathology revealed a high-grade sarcoma, not otherwise specified (NOS), with negative margins...

Tumor lysis syndrome (TLS) is an important oncological emergency that is usually observed with hematological malignancies and rarely with solid tumors. It can be induced either by therapy or spontaneously. Radiotherapy-induced TLS has been rarely reported in the literature. Here we present a patient with a diagnosis of metastatic prostate cancer and chronic lymphocytic leukemia complicated with TLS during palliative radiotherapy.

PURPOSE: Patient care within radiation oncology extends beyond the clinic or treatment hours. The on-call radiation oncologist is often not a patient's primary radiation oncologist, introducing the possibility of communication breakdowns and medical errors. This study analyzed after-hours telephone calls to identify opportunities for improved patient safety and quality of care. METHODS AND MATERIALS: Patient calls received outside of business hours between July 1, 2013, and June 30, 2014, at two academic radiation oncology departments were retrospectively reviewed...

MRI has superior soft-tissue definition compared with existing imaging modalities in radiation oncology; this has the added benefit of functional as well as anatomical imaging. This review aimed to evaluate the current use of MRI for lung cancer and identify the potential of a MRI protocol for lung radiotherapy (RT). 30 relevant studies were identified. Improvements in MRI technology have overcome some of the initial limitations of utilizing MRI for lung imaging. A number of commercially available and novel sequences have shown image quality to be adequate for the detection of pulmonary nodules with the potential for tumour delineation...

INTRODUCTION: Prostate cancer is now the third most frequent noncutaneous malignancy in Iranian men and the fifth most common cancer worldwide. Measurement of total serum prostate specific antigens (PSAs) has been one of the strongest predictors of biochemical progression and overall survival in determining the efficacy of definitive external beam radiation therapy in patients with localized prostate cancer. The aim of this research was to identify the 5-year biochemical progression-free survival (BFS) and related prognostic and predictive factors of localized prostate cancer patients who were treated with definitive external beam radiotherapy...

The adrenal gland is a common site of cancer metastasis. Surgery remains a mainstay of treatment for solitary adrenal metastasis. For patients who cannot undergo surgery, radiation is an alternative option. Stereotactic body radiotherapy (SBRT) is an ablative treatment option allowing larger doses to be delivered over a shorter period of time. In this study, we report on our experience with the use of SBRT to treat adrenal metastases using CyberKnife technology. We retrospectively reviewed the Winthrop University radiation oncology data base to identify 14 patients for whom SBRT was administered to treat malignant adrenal disease...

INTRODUCTION: Maintaining adequate nutrition for Head and Neck Cancer (HNC) patients is challenging due to both the malignancy and the rigours of radiation treatment. As yet, health behaviour interventions designed to maintain or improve nutrition in patients with HNC have not been evaluated. The proposed trial builds on promising pilot data, and evaluates the effectiveness of a dietitian-delivered health behaviour intervention to reduce malnutrition in patients with HNC undergoing radiotherapy: Eating As Treatment (EAT)...
