52 non-keratinzed epithelial carcinoma (NPC) patients treated by radiotherapy were studied in Thai Nguyen Central Hospital in 2002-2003 year period. Result showed the gender rate male/female = 1.7:1, the most common age: 40-60, ethnic groups: Kinh 48.1%, minority 51.9%, smoking rate: 93.9% in male. Most of tumor forms were revealed consisting of 61.5% mixed form 2.2%, underdermal form 13.5%. Pathoanatomically, undifferential carcinoma cosisted of 84.6%, NPC 3.84% and keratinized 11.53%. 55.8% of cases had responsiveness with radiotherapy and 5.8 no responsiveness. Common side effect was mouth drying 75%, weakenness of chewing muscle 76%, burn on radiated skin area 53.8%, swallowing difficulty 32.7%, reduce white blood count 38.5%, hair loss 11.5%

195 patients with tonsil carcinoma were treated by simple external radiation at K Hospital from January 1990 to January 2001. Results showed: the rate of response to simple external radiation in all episode was 58.9%, partial response 41.1%, no unresponsive case or progresive case. The rate of responsive effect of external radiation on tumor was T1, T2 - 100%, T3 - 47%, T4 - 0%, N1 - 100%; N2 - 82.4%; N3 - 20.4%. The responsive rate of external radiation on tumor and adenomas was depended mainly on the sign, the invasion of the tumor and the adenome, but no relation with histopathological type.

In oncologic practice, treatment guidelines provide appropriate treatment strategies based on evidence. Currently, many guidelines are used, including those of the European Association for the Study of the Liver and European Organization for Research and Treatment of Cancer (EASL-EORTC), National Comprehensive Cancer Network (NCCN), Asia-Pacific Primary Liver Cancer Expert (APPLE), and Korean Liver Cancer Study Group and National Cancer Centre (KLCSG-NCC). Although radiotherapy is commonly used in clinical practice, some guidelines do not accept it as a standard treatment modality. In this review, we will investigate the clinical practice guidelines currently used, and discuss the application of radiotherapy.

With the accumulation of clinical experiences, the efficacy of radiotherapy has been recognized in management scheme for HCC. While hepatologists are beginning to show less reluctance for applying radiotherapy to the treatment of HCC, it is necessary that the hepatologists be informed of the rapid developments in technical strategy for radiation oncology. Recent advances in several technologies have opened a new era in radiation oncology. Modern imaging technologies can provide a 3-dimensional model of patient's anatomy, and this allows radiation oncologists to identify accurate tumor volumes as well as the tumors' relationship with the adjacent normal tissues. Moreover, the development of the computer-controlled multileaf collimator systems now enables physicians to perform precise beam shaping and to modulate the radiation dose distribution. A combination of these systems, 3-DCRT, is rapidly replacing the more conventional 2-D radiotherapy. 3-DCRT has evolved into a more sophisticated technology, intensity modulated radiotherapy (IMRT). In IMRT, with the powerful computer-aided optimization process, the radiation dose can be delivered to the target using highly complex isodose profiles. This new technology has been further developed into IGRT, which combines the CT-images scanning system and radiation equipments into one hardware package, and this system is currently ready for clinical application. In parallel with the radiation technologies described above, the strategy of stereotactic radiation has evolved from the conventional linear accelerator-based system to a gammaknife, and more recently, to a cyberknife. These systems are primarily based on the concept of radiosurgery. Currently, various radiation technologies have been adopted for the radiotherapy of HCC. In this article, each strategy will be discussed as well as the indications for radiotherapy and the radiation-related complications.

To compare the performance of ArcCheck and film verification for volumetric intensity modulated arc therapy (VMAT) in the treatment of nasopharyngeal carcinoma, and to study the feasibility of ArcCheck in VMAT dosimetric verification. Five patients of nasopharyngeal carcinoma treated with VMAT were enrolled in this study. Dose verification was carried out by ArcCheck and film respectively. The result showed that there were no significant differences between ArcCheck and film verification. ArcCheck software can obtain three dimensional dose distribution directly with simple operation. It is convenient for ArcCheck to be used for VMAT dosimetric verification.
