Photodynamic therapy is mainly used in dermatology to treat skin tumors, precancerous lesions, and condyloma acuminatum. Due to its excellent tissue selectivity, easy operation and good cosmetic effect, it has been gradually applied to the treatment of various non-neoplastic skin diseases, such as verruca acuminata, acne, rosacea, chronic skin ulcer, fungal diseases, keloid, and so on. Here is the review on the advancement in photodynamic therapy for non-neoplastic skin diseases.

2.Trends in radiation therapy facilities-1986 to 1991.
Journal of Korean Medical Science 1993;8(4):267-270
The Korean Society of Therapeutic Radiology has periodically conducted a national survey on the status of radiation therapy facilities in Korea. This paper summarized survey data on the status of radiation therapy facilities, manpower, megavoltage equipments, patient load, types of procedures performed and characteristics of the patients treated.

4.Application and Development Trend of Medical Image Automatic Segmentation Technology in Radiation Therapy.
Chinese Journal of Medical Instrumentation 2020;44(5):420-424
The development of medical image segmentation technology has been briefly reviewed. The applications of auto-segmentation of organs at risk and target volumes based on Atlas and deep learning in the field of radiotherapy have been introduced in detail, respectively. Then the development direction and product model for general automatic sketching tools or systems based on solid clinical data are discussed.

For a long time past viruses have been recognized as being tumoricidal. At present, researchers are still pursuing studies and constructing more suitable oncolytic viruses for treating different malignant tumors. Herpes simplex virus type 1 (HSV-1) has been known as the most potential oncolytic virus among all the viruses. In this overview, we summarize the current situation of oncolytic viruses, the biology of HSV-1, its construction and application of its recombinant, and we debate on the feasibility and prospect of HSV-1 mutants labeled with radionuclides for cancer therapy.

Digital Image Communication in Medicine (DICOM) defines a standard method to store and transmit digital medical image information, in which there is a piece of implemented protocol named DICOM-RT that specially addresses both the transmission of radiation therapy image data and the ancillary data. In this paper, we firstly introduce the DICOM-RT with the emphases on its components, relationship with radiotherapy and how to produce the DICOM-RT object that refer to some certain radiotherapy information. Then we expatiate on the impact that benefits from applying DICOM-RT to radiotherapy, with an aid to accelerate its application in China.

To understand trends in the clinical characteristics of radiation oncology over the last 10 yr in Korea, annual survey questionnaires were sent to all of Korean radiation oncology facilities since 1990. Questionnaires addressed basic radiation therapy facilities and the clinical information. Responses were obtained from all facilities, and data collected from 1997 to 2006 was analyzed. The numbers of new patients that have undergone radiation therapy and the numbers of hospitals with a department of radiation oncology have steadily increased over the past 10 yr, and totaled 37,215 patients and 60 hospitals, respectively, in 2006. However, the proportion of patients irradiated among total cancer patients has remained below 30% over the last 10 yr. The numbers of prostate cancer, breast cancer, and hepatoma have increased by more than 3 fold over the past 10 yr. Moreover, the percentage of irradiated patients treated by brachytherapy was 10.3% in 1997, but this gradually fell to only 4.2% in 2006. The information collected described the role played by radiation oncology in Korea. Continuous surveys are required to enable trends to be detected.

9.The role of FDG-PET in the management of non-small cell lung carcinoma.
Annals of the Academy of Medicine, Singapore 2004;33(2):166-174
INTRODUCTIONPositron emission tomography (PET) using 18F-2-fluoro-2 deoxy-D-glucose (FDG) has been widely investigated and used in the non-invasive imaging of malignancy. Non-small cell lung carcinoma (NSCLC) is one of the most common and best validated indications for an FDG-PET scan. This review examines the roles of FDG-PET in the management of NSCLC and attempts to identify emerging uses and possible future developments.
MATERIALS AND METHODSLiterature review of English language literature indexed on Medline.
RESULTSThere is strong evidence to support the clinical efficacy and cost effectiveness of FDG-PET in the characterisation of solitary pulmonary nodules and in the staging of NSCLC. In addition, there are emerging uses in radiotherapy planning, monitoring of treatment response and prognostication.
CONCLUSIONSFDG-PET plays an integral role in the management of NSCLC and it is likely to expand as evidence supporting additional roles in the management of NSCLC becomes available.
