The preliminary analysis has been made of 73 patients who were treated in the Department of Radiation Therapy at Korea University Hospital for the lung cancer from April 1981 to December 1983. The patients were treated via Co-0 teletherapy unit and the doses were 5,400 rad/6 week for the curative, 3,600~4,500 rad/2 1/2~3 week for the palliative treatment. Thirty two (32/63=51%) patients have been for curative, 25/63 (40%) were for palliative, and 6/63 (9%) were for post-perative radiation. A post-adiation treatment, 28/63 (53%) were able to follow from 2 months to 3 yrs. During the follow up, chest X-ays and/or CT scans were taken and 22/27 (81.4%) of patients were responded more than 50% of tumor regression one month following completion of radiation.

Malignant lymphoma of the sinus is very rare but potentially radiocurable neoplasm. The disease is tend to be localized to the sinus and spread to adjacent local structure on initial presentation, and change to generalized lymphoma is uncommon. Most of sinus lymphoma is diffuse histiocytic type. Radiotherapy to the primary and neck nodes is the treatment of choice, and a survival rate of 50~70% can be expected.

Intraocular melanoma is the most common primary occular malignancy in adult above the age of 20. Before treatment of intraocular melanoma, it is essential to do complete work-ps including LFT (LDH, SGPT), chest X-ay, whole body bone scan. Also, liver-pleen and brain scan will be done if clinically indicated. Though, malignant melanoma is radioresistant, however, show rapid tumor shrinkage after irradiation with total tumor dose of 7,000 to 8,000 rads in 7- weeks.

Carcinoembryonic antigen (CEA) has been studied in the field of gynecologic malignancy to determine whether it can be used as a tumor marker for early detection of recurrence or evaluation of therapeutic results. From January 1985 through December 1989, a total of 239 cervical cancer patients were entered for an analysis of plasma CEA level in the group with cervical cancer compared to the control group consisting of 65 normal healthy women and 18 women with benign gynecologic disease. Plasma CEA levels appear to be directly related with the tumor extension and as stages advance, the incidence of patients with abnormal plasma CEA levels is increased. Also, there seems to be a little higher incidence of abnormal CEA levels in patients with adenocarcinomas or adenosquamous carcinoma but not statistically significant because of small number of patients. When the patients developed recurrence, plasma CEA levels are markedly elevated in the majority, particularly in patients with hepatic metastases. In conclusion, serial plasma CEA checks could be used to detect recurrence during follow-up after treatment of cervical cancer.

Sixty patients with head and neck carcinoma were studied retrospectively to assess the impact of treatment on survival and local control rate by stage in the Dept of Radiation Therapy, Korea University Had Wha Hospital between March 1981 and March 1986. Prior to definite radiotherapy, patients were evaluated by physical examination and radiologic studies including hest, paryngogram and CT scan and then these patients were grouped according to the American Joint Committee(AJC) staging system. They were Treated with RT alone or postoperative irradiation to the dose of 7,200 cGy/8 weeks and 6,000 cGy/7 weeks respectively. The results were obtained and as follows; 1. overall male to female sex ratio was 3.6:1. The peak age of patients with head and neck cancer was 6th decade. 2. In all patients treated by RT, the ratio of squamous cell carcinoma to non-squamous cell carcinoma was 3.5:1 (60/77 patients). 3. The incidence according to the anatomic site of primary tumor was 22 cases in the larynx, 12 cases in PNS, 7 cases in nasopharynx, 6 cases in oropharynx, and 3 cases in hypopharynx. 4. According to AJC staging system, 4 cases were Stage I, 7 in Stage II, 19 in Stage III and 27 in Stage IV. 5. The overall incidence of cervical lymph node metastases was 43% and subdigatric and submaxillary triangle lymph nodes were the most frequent site of metastases. 6. Local control was achieved in 48% of patients treated by radio-therapy. 7. The lung was the most common site for distant metastases, comprising 4 cases among 7 cases in which distant metastases occurred. 8. The overall estimated 5-year survival rate was 43% in the head and neck cancer treated with radiotherapy by life-table analysis.

Background: This study aimed to generate a Z score calculation model for coronary artery diameter of normal children and adolescents to be adopted as the standard calculation method with consensus in clinical practice. Methods: This study was a retrospective, multicenter study that collected data from multiple institutions across South Korea. Data were analyzed to determine the model that best fit the relationship between the diameter of coronary arteries and independent demographic parameters. Linear, power, logarithmic, exponential, and square root polynomial models were tested for best fit. Results: Data of 2,030 subjects were collected from 16 institutions. Separate calculation models for each sex were developed because the impact of demographic variables on the diameter of coronary arteries differs according to sex. The final model was the polynomial formula with an exponential relationship between the diameter of coronary arteries and body surface area using the DuBois formula. Conclusion A new coronary artery diameter Z score model was developed and is anticipated to be applicable in clinical practice. The new model will help establish a consensus-based Z score model.

Given the progressive improvements in antithrombotic strategies, management of cardiovascular disease has become sophisticated/refined. However, the optimal perioperative management of antithrombotic therapy in patients with acute coronary syndrome or who are scheduled for percutaneous coronary intervention remains unclear. Assessments of the thrombotic and hemorrhagic risks are essential to reduce the rates of mortality and major cardiac events. However, the existing guidelines do not mention these topics. This case-based consensus document deals with common clinical scenarios and offers evidence-based guidelines for individualized perioperative management of antithrombotic therapy in the real world.

The prevalence of ischemic heart disease is steadily growing as populations age. Antithrombotic treatment is a key therapeutic modality for the prevention of secondary cerebro-cardiovascular disease. Patients with acute coronary syndrome or who are undergoing percutaneous coronary intervention must be treated with dual antiplatelet therapy for a mandatory period. The optimal perioperative antithrombotic regimen remains debatable; antithrombotics can cause bleeding. Inadequate antithrombotic regimens are associated with perioperative ischemic events, but continuation of therapy may increase the risks of perioperative hemorrhagic complications (including mortality). Many guidelines on the perioperative management of antithrombotic agents have been established by academic societies. However, the existing guidelines do not cover all specialties, nor do they describe the thrombotic and hemorrhagic risks associated with various surgical interventions. Moreover, few practical recommendations on the modification of antithrombotic regimens in patients who require non-deferrable interventions/surgeries or procedures associated with a high risk of hemorrhage have appeared. Therefore, cardiologists, specialists performing invasive procedures, surgeons, dentists, and anesthesiologists have not come to a consensus on optimal perioperative antithrombotic regimens. The Korean Platelet-Thrombosis Research Group presented a positioning paper on perioperative antithrombotic management. We here discuss commonly encountered clinical scenarios and engage in evidence-based discussion to assist individualized, perioperative antithrombotic management in clinical practice.

Background: There has been no comparison of the determinants of admission route between acute ischemic stroke (AIS) and acute myocardial infarction (AMI). We examined whether factors associated with direct versus transferred-in admission to regional cardiocerebrovascular centers (RCVCs) differed between AIS and AMI. Methods: Using a nationwide RCVC registry, we identified consecutive patients presenting with AMI and AIS between July 2016 and December 2018. We explored factors associated with direct admission to RCVCs in patients with AIS and AMI and examined whether those associations differed between AIS and AMI, including interaction terms between each factor and disease type in multivariable models. To explore the influence of emergency medical service (EMS) paramedics on hospital selection, stratified analyses according to use of EMS were also performed. Results: Among the 17,897 and 8,927 AIS and AMI patients, 66.6% and 48.2% were directly admitted to RCVCs, respectively. Multivariable analysis showed that previous coronary heart disease, prehospital awareness, higher education level, and EMS use increased the odds of direct admission to RCVCs, but the odds ratio (OR) was different between AIS and AMI (for the first 3 factors, AMI > AIS; for EMS use, AMI < AIS). EMS use was the single most important factor for both AIS and AMI (OR, 4.72 vs. 3.90). Hypertension and hyperlipidemia increased, while living alone decreased the odds of direct admission only in AMI;additionally, age (65–74 years), previous stroke, and presentation during non-working hours increased the odds only in AIS. EMS use weakened the associations between direct admission and most factors in both AIS and AMI. Conclusions Various patient factors were differentially associated with direct admission to RCVCs between AIS and AMI. Public education for symptom awareness and use of EMS is essential in optimizing the transportation and hospitalization of patients with AMI and AIS.
