Purpose: This study was conducted to 1) find out the frequency of tobacco control intervention, barriers, and facilitators. 2) compare the differences in tobacco control intervention, barriers, and facilitators between oncology nurses and general nurses. Method: A sample was composed of 96 oncology nurses and 284 general nurses. The survey questionnaire was mailed out to nurses who were working at the randomly selected hospitals throughout the country. The questionnaire was adopted from the study of national survey on oncology nurse's tobacco interventions in United States by Sarnar, et al.(2000). Results: Oncology nurses were found to provide tobacco control interventions more frequently comparing to the general nurses. "Patient not motivated to quit smoking", "Lack of time", "Lack of recognition/rewards", were the most commonly identified barriers. "Patient wants to quit", "Adequate time", "Confidence in ability help people to stop smoking", were the most commonly identified facilitators. Conclusions: Although oncology nurses are in an important position in delivering tobacco interventions and providing resources, their participation in consistent delivery of a tobacco control intervention was less than desirable. To help nurses participate in the assessment of tobacco use and interventions for cessation, the development of educational program is necessary.

This study is the retrospective evaluation of ninety-six patients with biopsy-proven carcinoma of nasopharynx treated with radiotherapy at Yonsei University, College of Medicine, Radiation Oncology from January 1971 to December 1985. Patient's age ranged from 15 to 71 years with a median age of 49 years. Fifty-two point five percent of local control and $47.5\%$ of actuarial 5 year survival were achieved with radical radiotherapy. Five year survival rate for Stage I&II, III and IV were $75.0\%,\;74.6\%\;and\;41.4\%$, respectively. Distant metastasis rate was related with N stage $(N1\;12.5\%,\;N1\;0\%,\;N2\;23.5\%,\;N3\;32.1\%$and histologic type (lymphoepithelioma $41.7\%$, squamous cell carcinoma $6.5\%$) but not with T stage. Thirty-one of sixty-seven patient covered adequate radiation field received induction chemotherapy. However induction chemotherapy does not appear to improve over all survival.

To appropriately control or compensate breathing motion of targets in thorax or abdomen during radiotherapy is still demanding. Our idea is that a visual signal may help regulate patient's breathing pattern, by controlling its amplitude and cycle. The system involving breathing control with a visual signal for aperture maneuver with controlled breath (AMC) has been developed. A thermocouple is used to detect the temperature change due to patient's breathing. The system also consists of a mask, in which the thermocouple is installed, an operational amplifier, a converter, etc. Patients were instructed to control their respiration by breathing following the visuals signal, as watching a display that shows both patients' current breathing pattern and the signal. The patterns of patients' controlled breathing and the signals coincided well. Therefore, when AMC technique is applied, a target moves in the range that is 60 % less than the range of free breathing motion with the help of the system and so target margins can be reduced significantly. This study reveals that a visual signal is not only useful to control patient's breathing but also clinically effective.

Although significant advances in the treatment of intrahepatic lesions, it is reported that the prognosis for patients with hepatocellular carcinoma (HCC) who have extrahepatic metastasis remains poor. We report a patient with lung, liver, brain, bone and subcutaneous metastasis from HCC who has survived more than 7 years maintaining relatively good performance status as a result of repeated therapies. A 55-year-old male patient with HCC underwent right lobectomy of the liver and cholecystectomy in September 2006. He received wedge resection for lung metastasis twice (July 2009, January 2011) and Gamma Knife stereotactic radiosurgery for brain metastasis (April 2011). Over the last 3 years, he has developed metastasis in subcutaneous tissues, muscle, and bone with pain. He has undergone 7 courses of radiotherapies for subcutaneous tissues, muscle, and bone metastasis and been prescribed sorafenib and he is still capable of all self-care.

Cancer patients frequently experience malnutrition. Cancer and cancer therapy effects nutritional status through alterations in the metabolic system and reduction in food intake. In the present study, fifty seven cancer patients were selected as subjects from the oncology ward of Cachar Cancer Hospital and Research Centre, Silchar, India. Evaluation of nutritional status of cancer patients during treatment was carried out by scored Patient-Generated Subjective Global Assessment (PG-SGA). The findings of PG-SGA showed that 15.8% (9) were well nourished, 31.6% (18) were moderately or suspected of being malnourished and 52.6% (30) were severely malnourished. The prevalence of malnutrition was highest in lip/oral (33.33%) cancer patients. The study showed that the prevalence of malnutrition (84.2%) was high in cancer patients during treatment.

In the clinical state of oligometastases or oligorecurrence, a transitional state between localized and widespread systemic disease, local control of the disease may yield improved systemic control. Radiotherapy may be a good means for controlling oligometastatic tumors, particularly in very old patients for whom surgery may be infeasible. A combination of systemic therapy and local therapy is necessary to prevent systemic progression. Some kinds of cancers found in the elderly are known to be somewhat indolent for systemic progression. So, for very old patients who refuse or cannot tolerate chemotherapy, the use of radical radiotherapy alone to treat oligorecurrences may be very helpful. We successfully treated an 87-year-old patient who had been diagnosed with oligorecurrences three times over six years with radiotherapy alone. The patient is now, about four years after his first radiotherapy for liver metastasis, alive without any evidence of cancer and with fully active performance status.

Purpose: To report the initial experience of patient-specific quality assurance (pQA) for the wobbling and line-scanning proton therapy at Samsung Medical Center. Materials and Methods: The pQA results of 89 wobbling treatments with 227 fields and 44 line-scanning treatments with 118 fields were analyzed from December 2015 to June 2016. For the wobbling method, proton range and spread-out Bragg peak (SOBP) width were verified. For the line-scanning method, output and two-dimensional dose distribution at multiple depths were verified by gamma analysis with 3%/3 mm criterion. Results: The average range difference was -0.44 mm with a standard deviation (SD) of 1.64 mm and 0.1 mm with an SD of 0.53 mm for the small and middle wobbling radii, respectively. For the line-scanning method, the output difference was within ${\pm}3%$. The gamma passing rates were over 95% with 3%/3 mm criterion for all depths. Conclusions: For the wobbling method, proton range and SOBP width were within the tolerance levels. For the line-scanning method, the output and two-dimensional dose distribution showed excellent agreement with the treatment plans.

I. 서론 및 실험목적 방사선 치료에 있어 환자의 고정(immobilization)은 치료의 성적을 결정할 수 있는 중요한 요인이라 할 수 있다. 방사선 치료방법이 수없이 변화하고 발전을 거듭했음에도 불구하고 하나의 과제로 남아있는 것이 환자를 고정하는 것과 재현성의 유지라 할 수 있겠다. 이에 본원에서는 직장암 환자 중 복회음부 절제술 환자에 있어 setup의 재현성을 유지하여 보다 정확한 치료를 위해 본 고정용구를 제작하였고 그 유용성을 평가하는데 목적이 있다. II. 대상 및 실험방법 본원에서 치료를 받고있는 직장암환자 중 복회음부 절제술 환자를 대상으로 하였고, 환자의 병변 부위의 해부학적인 정보를 기본으로 고정용구를 제작하였다. 자체 제작한 고정용구를 환자에게 적용하여 Setup의 재현성과, 변화 및 오차를 비교분석 하였다. III. 결 과 복회음부 절제술 환자 중 고정용구를 사용하지 않은 환자는 set-up 후 일정시간에 $5mm{\sim}1cm$ 내외의 Set-up의 변화 및 오차가 발생하였고, 고정용구를 사용한 환자의 경우는 set-up 의 변화 및 오차를 수mm이내로 줄임으로써 재현성의 유지가 가능하며 복회음부 절제술 환자의 불안전한 자세로 인한 환부부위 통증을 감소시킴으로써 인위적으로 치료 자세를 유지해야하는 불편함을 해소하여 재현성 및 정확도를 향상시킨 치료가 가능하게 되었다. IV. 결론 및 고찰 본원에서 치료를 받고있는 직장암환자 중 복회음부 절제술 환자에게 고정용구를 사용함으로써, 고정용구를 사용하지 않았을 때의 환자의 set-up 변화로 인한 resetup의 번거러움을 줄일 수 있었고 환자에게 인위적으로 치료 자세를 유지해야하는 불편함을 해소할 수 있었다. 궁극적으로는 set-up의 재현성을 유지해 보다 정확한 치료를 가능하게 했고 앞으로 이 고정용구를 보완, 개선시켜서 환자의 치료에 활용한다면 더욱더 질적으로 향상된 치료를 제공 할 수 있을 것으로 사료된다.

The shortage of nursing personnel was become one of the most serious problems in operating pediatric oncology nursing unit which was the first pediatric oncology nursing unit in Korea. The purpose of this study was to estimate the optimal number of nursing personnel by calculating nursing care hours. The subjects were 13 staff nurses and inpatients of pediatric oncology nursing unit at Seoul National University Hospital during the period of May 20, 1996, to June 2, 1996. The number of nurses' duty was 132, the number of patients treated was 1288 for these 2 weeks. The tools used for this study were pediatric patient classification indexes and direct & indirect care indexes. Each nurse measured the time that they spent for their activities by self record under the supervision of their nurse manager. The method used to calculate the number of nursing personnel was multiplication of the average number of nursing care hours per patient per day with the number of patients. Percentage, average, t-test, F-test were used for data analysis. The results of this study were as follows : 1) The distribution of patient class : Class I & II none, Class III 86.8%. Class IV 12.9% 2) Direct nursing care hours for a patient per shift according to patient classification: Class III : 27.64 minutes, Class IV : 54.64 minutes The average direct nursing service hours for a patient per shift(3 shift) was 31.54 minutes(94.62 m/day). The average indirect nursing service hours for each patient per duty(3 shift) is 21.3 minutes (63. 91 m/day). 3) The average nursing hours for a patient per duty was 52.80 minutes(2.64h/day). 4) The group of administering medications in direct care activities showed the highest percentage (38.9%). Checking vital signs among observation took the most time am.ong each direct care activity (6.88 minutes for a patient per duty). 5) Charting took the most time of each indirect care activity(52.53 minutes/ duty/nurse). 6) The average personal time per duty is 29.40 minutes, which 'was below 30 minutes of this hospital regulations. 7) The average nursing hours that a nurse provided for a duty was 8.60 hours, which meant that a nurse worked 1.10 hours overtime. 8) Standardizing to a 33 bed to a unit, 17 nurses were needed at the present nursing level.
