Gastric cancer is the third most common cause of cancer death worldwide, although it is not in the top 10 causes of cancer death in Northern America. Due to clear differences in incidence, screening, risk factors, tumor biology, and treatment between gastric cancers from Eastern and Western countries, our treatment is primarily guided by trials from Western countries. Patients undergo an extensive staging evaluation including high-quality CT imaging, endoscopic ultrasound, and diagnostic laparoscopy with peritoneal washings for cytology...

Renal Cell Carcinoma (RCC) has historically been considered a radioresistant cancer, and radiotherapy was usually delivered with a palliative goal. Stereotactic ablative radiotherapy (SABR) allows the delivery of high doses on small treatment volumes in a safe and effective way, thus opening the doors to new applicationsof radiotherapy both in the treatment of the primary and oligometastasic disease. Aim of the current review is to explore the state of art of SABR in the therapeutic approach to RCC.

INTRODUCTION: To investigate the efficacy and toxicity of radiation therapy (RT) after radical prostatectomy (RP) for prostate cancer at Radiation Oncology Centres, Toowoomba. METHODS: The electronic medical records of 130 consecutive patients with histologically proven prostate adenocarcinoma who underwent post-prostatectomy RT between January 2008 and December 2014 were analysed. Primary endpoint was Biochemical Recurrence (BCR) after RT. BCR was defined by PSA > 0...

Implementing targeted drug therapy in radio-oncologic treatment regimens has greatly improved the outcome of cancer patients. However, the efficacy of molecular targeted drugs such as inhibitory antibodies or small molecule inhibitors essentially depends on target expression and activity, which both can change during the course of treatment. Radiotherapy has previously been shown to activate pro-survival pathways which can help tumor cells to adapt and thereby survive treatment. Therefore, we aimed to identify changes in signaling induced by radiation and evaluate the potential of targeting these changes with small molecules to increase the therapeutic efficacy on cancer cell survival...

INTRODUCTION: Underutilisation of radiotherapy has been observed worldwide. To evaluate the current situation in Belgium, optimal utilisation proportions (OUPs) adopted from the European SocieTy for Radiotherapy and Oncology - Health Economics in Radiation Oncology (ESTRO-HERO) project were compared to actual utilisation proportions (AUPs) and with radiotherapy advised during the multidisciplinary cancer team (MDT) meetings. In addition, the impact of independent variables was analysed...

PURPOSE: To compare vaginal control and treatment toxicity of three different high-dose-rate brachytherapy schedules as exclusive treatment in postoperative endometrial carcinoma. METHODS AND MATERIALS: From 2003 to 2015, three different schedules were used as postoperative treatment for 146 patients (p) with intermediate-risk endometrial carcinoma. Group 1 (41 p): six fractions of 4-6 Gy, 3-4 fractions per week; Group 2 (59 p): four fractions of 5-6 Gy administered daily; Group 3 (46 p): 6 Gy × 3 fractions in three consecutive days...

INTRODUCTION: Retinoblastoma represents only 3% of paediatric cancers, but it is the most prevalent intraocular tumour in this population. It develops in the retina as a primitive neuroectodermal tumour that affects development during gestation. The tumour presents in two different forms depending on whether or not it expresses a genetic modification. For patients diagnosed at preschool age, 75% are unilateral non-hereditary cases. While enucleation is the preferred treatment for advanced stages of the tumour, other modalities, such as systemic and intraocular chemotherapy, radiotherapy and local treatments with thermotherapy, cryotherapy, and brachytherapy can be used to try to preserve the eye...

CONTEXT: Most of the reviews on the biological basis for symptom clusters suggest that inflammatory processes are involved in the development and maintenance of the symptom clusters. However, no studies have evaluated for associations between genetic polymorphisms and common symptom clusters (e.g., mood disturbance, sickness behavior). OBJECTIVES: Examine the associations between cytokine gene polymorphisms and the severity of three distinct symptom clusters (i...

Thoracic radiotherapy causes damage of normal lung tissue, which limits the cumulative radiation dose and, hence, confines the anticancer efficacy of radiotherapy and impacts the quality of life of tumor patients. Ras-homologous (Rho) small GTPases regulate multiple stress responses and cell death. Therefore, we investigated whether pharmacological targeting of Rho signaling by the HMG-CoA-reductase inhibitor lovastatin influences ionizing radiation (IR)-induced toxicity in primary human lung fibroblasts, lung epithelial and lung microvascular endothelial cells in vitro and subchronic mouse lung tissue damage following hypo-fractionated irradiation (4x4 Gy)...

BACKGROUND: The vascular fibula flap is an ideal choice for function and appearance reconstruction of mandible. Despite the high success rate, "late complications" such as Ti plate exposure and local infection related to osteosynthesis are not uncommon. PATIENTS AND METHOD: A retrospective cohort of patients who received vascular fibula reconstruction for mandible from January 2011 to December 2013 from the Department of Oral and Maxillofacial Oncology in a tertiary hospital were charted: clinical, pathological, and therapeutic factors were analyzed for late complications in univariate and multivariate analyses...

OBJECTIVE: The Children's Oncology Group study AREN0534 aimed to improve event-free survival (EFS) and overall survival (OS) while preserving renal tissue by intensifying preoperative chemotherapy, completing definitive surgery by 12 weeks from diagnosis, and modifying postoperative chemotherapy based on histologic response. BACKGROUND: No prospective therapeutic clinic trials in children with bilateral Wilms tumors (BWT) exist. Historical outcomes for this group were poor and often involved prolonged chemotherapy; on NWTS-5, 4-year EFS for all children with BWT was 56%...

REVIEW
Dilan A Patel, Jian L Campian
Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established...

BACKGROUND: Acute oral mucositis is a common complication of radiotherapy for nasopharyngeal carcinoma (NPC) patients. OBJECTIVES: The aim of the study was to observe the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on radiotherapy-induced oral mucositis in locally advanced NPC patients. MATERIAL AND METHODS: The study involved 64 locally advanced NPC patients that were randomly allocated to receive either rhG-CSF mouthwash (2 μg/mL rhG-CSF; group A, n = 34) or a compounded mouth rinse (10 μg/mL vitamin B12, 0...

Radiation technique for prostate cancer has continuously evolved over the past several decades. The aim of the present study was to describe the effects of implementing modern prostate intensity-modulated radiation therapy (M-IMRT) on dosimetry and outcome. Between January 2010 and April 2012, 48 consecutive patients were treated with conventional prostate IMRT (C-IMRT) to a dose of 81 Gy. Between May 2012 and April 2015, 50 consecutive patients were treated with M-IMRT to the entire prostate to a dose of 75...

Purpose Treatment of oropharyngeal squamous cell carcinoma (OPSCC) is evolving toward risk-based modification of therapeutic intensity, which requires patient-specific estimates of overall survival (OS) and progression-free survival (PFS). Methods To develop and validate nomograms for OS and PFS, we used a derivation cohort of 493 patients with OPSCC with known p16 tumor status (surrogate of human papillomavirus) and cigarette smoking history (pack-years) randomly assigned to clinical trials using platinum-based chemoradiotherapy (NRG Oncology Radiation Therapy Oncology Group [RTOG] 0129 and 0522)...
