Primary small cell carcinoma of the esophagus is a very rare cell type in esophageal cancer and an extremely aggresive tumor with grave prognosis. Because of the highly malignant potency, chemotherapy for the primary therapy of small cell carcinoma is accepted generally. We experienced a case of small cell carcinoma of the lower esophagus. The patient was a 53 year-old male with regional Iymph node metastasis and managed with complete resection and chemotherapy.

Recent advances in techniques and strategies use to detect cancer in its early stages and to treat it effectively has the survival rate of cancer patients and the number of long-term cancer survivors continually increasing. Unfortunately, many cancer survivors are at risk for various late and long-term effects of cancer treatments including the radiotherapy. Long-term cancer survivors can be also seen for a hospice and palliative care because of cancer recurrence and they are at risk of delayed reactions to radiotherapy. So, the understanding and knowledge of radiation reactions is required for the proper medical diagnosis, management, and coordination of the potential reactions that may occur in these care setting. In effort to increase the survival rate in cancer patients and to decrease the adverse effects of cancer treatment, many clinical studies have been and continue to be conducted. The efforts of these studies have thus resulted in the advancement of cancer treatments. Regrettably, the overall interest in how to manage adverse effects of cancer treatment such as radiotherapy appears seemingly low in clinical practice and its advanced studies as a whole are delayed and deficient. It is imperative that the medical community show an enthusiastic interest in the aftercare of cancer patients and cancer survivors in order to create a complementary integrative approach that will eliminate radiotherapy related pain/discomfort or illness in hospice and palliative care settings.

Purpose: The purpose of this study was to analyze the results of treatment and prognosis of Marjolin's ulcer compared with primary squamous cell carcinoma. Materials and Methods: Fourteen patients treated for Marjolin's ulcer were analyzed. Twenty patients with primary squamous cell carcinoma treated during the same time period was the control group. Mean age was 61.2 years. There were 24 males and 10 females. The locations, TNM stages, histological grades, recurrence, metastasis, and survival rate were analyzed and compared between two groups. Results: The mean follow-up period was 54.8 months (range, 12-168 months). Local recurrences were found in 6 cases, 5 ones in Marjolin's ulcer patients, and one case in primary squamous cell carcinoma patients. The mean time interval between the initial presentation and occurrence of local recurrences was 9 months (range, 2-20 months). There were 6 metastases. 2 (14.3%) metastases were found in Marjolin's ulcer patients, and 4 (20.0%) metastases in primary squamous cell carcinoma patients. Total events (metastasis or local recurrence) were found in 10 pateients, 6 of them in Marjolin's ulcer group, and the remaining four in primary group. 5-year disease-free survival rate was 64.3% in Marjolin's ulcer group and 95.0% in primary squamous cell carcinoma group. Conclusion: Squamous cell carcinomas originating as Marjolin's ulcers revealed higher recurrence rate and lower survival rate despite of aggressive treatment. Therefore, new treatment modalities should be developed for improving outcomes.

방사선 치료를 받는 모든 환자의 경우 먼저 모의 치료를 시행한 후에 동일한 자세로 방사선 치료를 실시한다. 이 때 무엇보다도 중요한 사항은 정확한 자세의 재현성이다. 직장암 환자의 방사선 치료를 시행하는 경우에도 모의 치료와 동일한 자세 유지가 요구되어진다. 하지만 호흡 및 환자의 여러 가지 요소에 의해 자세의 오차가 발생할 수 있다. 이에 본 논문은 직장암 환자의 방사선 치료를 시행하는 경우 오차가 발생할 수 있는 요소 중에 환자의 체지량 지수 차이에 의한 자세 재현성에 대해 알아보고 향후 자세 오차를 줄일 수 있는 방법을 모색하고자 한다.

방사선치료후 재발성 또는 잔존성 두경부암의 수술후에 피부판의 괴사 및 slough, 감염, 누공, 부종과 경동맥 노출 심지어는 경동맥 파열 등의 술후 합병증이 빈발함으로 수술에 큰 어려움을 겪게 된다. Pectoralis major myocutaneous flap은 진행된 두경부암의 광범위한 절제후에 그 결손부를 보충해 주는 데 좋은 방법으로 사용할 수 있을 뿐아니라 방사선치료후에 생긴 합병증에도 이 flap을 이용하여 좋은 치료결과를 얻을 수 있다. 저자들은 수술 전에 방사선치료를 받고 심한 부종으로 후두조직의 괴사 및 기능이 손실된 환자와 방사선 치료후 재발된 상인두암환자의 경우에서 수술 후 생긴 pharyngocutaneous fistula와 피부판감염 및 경동맥노출 등으로 치유가 곤란하여 여기에 pectoralis major myocutaneous flap을 사용하여 pharyngostoma를 재건하고 노출된 경동맥부위를 보호하여 좋은 치료효과를 얻었기에 문헌을 고찰하여 보고하는 바이다.

Purpose: This study aims to contribute to the reduction of complications of breast cancer radiation therapy by analyzing skin dose differences due to Set-up error. Materials and Method: Pseudo breast was produced using a 3D printer, applied to the phantom, and images were acquired through CT. Treatment plan was carried out that the PTV, which contains 95% of the prescription dose, could be more than 95% of the volume, so that Dmax did not exceed 107% of the prescription dose. The Set-up error was evaluated by applying ±1mm/±3mm/±5mm to the X-axis, Y-axis, and Z-axis. Results: The dose-variation in skin due to Set-up error was approximately 106% to 123% compared to prescription dose, and the highest dose in skin was 49.24 Gy at 5mm Set-up error in the lateral direction of the X-axis. More than 107% of the prescription dose was the widest at 6.87 cc in skin lateral. Conclusions: If a Set-up error occurs during left breast cancer VMAT, a great difference in skin dose was shown in the lateral direction of the X-axis. If more effort is made to align the X-axis of the breast treated during CBCT registration, the dose-variation of skin will be reduced.

Clinical research on acupuncture in cancer care is a new and challenging field in oncology. The results of clinical research will continue to provide clinically relevant answers for patients and oncologists. The evidence currently available has suggested that acupuncture is a safe and effective therapy to manage cancer and treatment related symptoms, while giving patients the ability to actively participate in their own care plan. The article explains the potential benefits of acupuncture and describes the difficulties in studying its effectiveness.

This study is to find a service that improves the subjective happiness of cancer patients that receive radiation therapy. One hundred and one cancer patients undergoing radiation therapy were enrolled in the survey to verify the self-consciousness and symptom distress that could affect the subjective happiness. Independent t-test, one-way analysis of variance, and Pearson correlation were conducted with the SPSS 20.0 program. Symptom distress of cancer patients undergoing radiation therapy showed highest in the order of fatigue, appearance changes, dizziness, loss of appetite, and sleep disorders. And lower symptom distress, higher private self-consciousness were significantly correlated with higher subjective happiness among patients receiving radiation therapy for cancer. Study findings reflect the necessity of an integrative approach combining physical, psychological and emotional interventions during a radiotherapy period. For this cause, it would be necessary to supplement previously existing service programs and organize a patient-friendly system that could affiliate regional cancer centers or Public health centers with the hospitals in which the patients are being treated.

목적: 본 연구는 방사선치료를 받는 유방암 환자의 증상경험, 정서적 상태와 사회적지지 및 관련 변수간의 관계를 파악하기 위한 서술적 상관관계 연구이다. 방법: 연구대상자는 T시에 위치한 2개 대학병원에서 방사선 치료를 받는 유방암 환자 126명으로, 연구도구는 일반적 특성과 증상경험, 정서적 상태 및 사회적지지를 측정하기 위한 도구로 구성된 질문지이다. 결과: 연구 대상자의 증상경험은 21.96(SD = 14.14), 정서적 상태는 110.95(SD = 100.92), 사회적지지는 3.70(SD = 0.98)로 나타났다. 증상경험과 정서상태는 유의한 정 상관관계(r = .396, p = .001)를 나타내었고, 증상 경험과 사회적지지는 유의한 부적 상관관계(r = -.304, p = .003)를 나타내었다. 증상경험에 영향을 미치는 요인은 정서적 상태로 설명력이 16.5%이었다. 제언: 이상의 연구결과 방사선치료를 유방암 환자의 증상경험과 환자의 정서적 상태가 관련이 됨을 알 수 있으나, 그 설명력은 약하므로 앞으로 더 연구하여야 할 영역이라 생각한다.

기관연골까지만 침윤된 갑상선암에서 침윤된 기관연골을 면도식으로 깍아 내는 술식을 선택했을때 효과적인 치료방법이 되는가를 알아보기 위하여 본 연구를 실시하였다. 1979년 부터 1988년까지 10년간수술이 시행된 갑상선암환자 432예중 기관연골까지만 침윤된 환자는 16예 이였다. 남자가 3예, 여자가 13예 이었으며, 이들의 평균 연령은 55.8세 이었고, 조직학적으로는 유두상암이 14예, 여포상암이 2예 였다. 전예에서 침윤된 기관연골을 면도식으로 깍아내였으며, 수술후 보조치료로 방사성 동위원소 치료나 외부 방사선 조사를 추가하였고, 또한 갑상선 홀몬 투여로 TSH 억제 치료를 하였다. 평균 추척 기간은 67.7개월이었다. 16예중 무병생존은 4예에 불과하였고, 12예가 치료에 실패했는데 이중 7예는 갑상선암의 재발로 사망하였다. 이상의 결과로 면도식 절제술은 갑상선암이 기관연골에 침윤되었을 때의 술식으로는 부적당하며 무병 생존율을 향상시키기 위해서는 비록 표재성인 기관연골 침윤이라도 기관제술과 같은 적극적인 술식 선택이 바람직하다고 사료되었다.
