PURPOSE This study examined the status of radiation-induced liver injury in adjuvant or palliative gastric cancer radiation therapy (RT), identified risk factors of radiation-induced liver injury in gastric cancer RT, analysed the dose-volume effects of liver injury, and developed a liver dose limitation reference for gastric cancer RT. METHODS AND MATERIALS Data for 56 post-operative gastric...

In 2016, 13 topics were selected as major research advances in gynecologic oncology. For ovarian cancer, study results supporting previous ones regarding surgical preventive strategies were reported. There were several targeted agents that showed comparable responses in phase III trials, including niraparib, cediranib, and nintedanib. On the contrary to our expectations, dose-dense weekly chemo...

objective(s): radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. a prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer. methods: to minimize potential confounding fact...

PURPOSE The clinical outcomes and complications of tension-band plating have been well documented, and commonly include a post-operative delay in return of function. We performed a retrospective comparison study to evaluate the capacity of immediate post-operative physical therapy to prevent this post-operative delay in return of function. METHODS Sixty-seven consecutive growth-deformity pati...

Background: Radiation therapy is among the most conventional cancer therapeutic modalities with effective local tumor control. However, due to the development of radio-resistance, tumor recurrence and metastasis often occur following radiation therapy. In recent years, combination of radiotherapy and gene therapy has been suggested to overcome this problem. The aim of the current study was to e...

an important need in radiation therapy is a fast and accurate treatment planning system. this system using ct data and characteristics of the radiation beam, calculates the dose in all points of the patient’s volume. two main factors in planning system are “accuracy” and “speed”. according to these factors, various generation of treatment planning systems are developed.   this article is the re...

INTRODUCTION AND PURPOSE In gall bladder cancers, even after curative surgery, survivals are dismal and loco-regional failure accounts for 40-86%. Although these are considered radio-resistant, adjuvant radiation, with or without chemotherapy, has been tried to improve loco-regional control and overall survival rates. With an aim to evaluate the natural history of gall bladder cancers, role of ...

Abstract BACKGROUND Intraoperative radiotherapy (IORT) has emerged as a viable tool for consolidation of surgery and radiation brain metastases into single episode care, but its relative novelty compared to SRS or fractionated warrants evaluation safety. While post-operative seizure risk is typically minimal with the use anti-epileptic drugs during peri-operative phase, intra-operative epilepti...
