There is no established treatment for esophageal carcinoma with metastasis. For the metastatic esophageal squamous cell carcinoma, chemotherapy or best supportive care according to patient's performance status are accepted as an available treatment. We report a case of complete remission after concurrent chemoradiotherapy for esophageal squamous cell carcinoma with metastatic lesion in 5th thoracic vertebrae. A 57-year-old man with ongoing dysphagia and weight loss was admitted to our hospital. On the endoscopic and radiologic imaging evaluation,the patient was diagnosed as a squamous cell carcinoma of esophagus with solitary metastatic lesion in 5th thoracic vertebrae. The patient was treated with combination chemotherapy (5-fluorouracil (5-FU) and cisplatin) and concurrent radiotherapy for two months to relieve dysphagia. Because metastatic lesion in thoracic vertebrae was located near the primary esophageal tumor, the metastatic lesion could be included within the radiation field. After concurrent chemoradiotherapy, consecutive 4 cycles of chemotherapy had been carried out. Primary esophageal tumor with metastatic lymph nodes and metastatic lesion in 5th thoracic vertebrae disappeared on follow up computed tomography (CT) and positron emission tomography-CT (PET-CT). Follow up endoscopic biopsy revealed no remnant malignant cells at previous primary cancer lesion.

Metallothioneins (MT) are a group of low-molecular weight, cysteine-rich, intracellular proteins that are encoded by a family of genes containing at least 10 functional isoforms in human. The expression and induction of these proteins is associated with protection against DNA damage, oxidative stress, and apoptosis. Many studies have shown increased expression of MT in various human tumors, whereas MT is down-regulated in certain tumors such as hepatocellular carcinoma and liver adenocarcinoma. Hence, the expression of MT is not universal to all human tumors but may depend on the differentiation status and proliferative index of tumors, along with other tissue factors and gene mutations. Using Northern blot analysis, we found that laminin induced expression of MT-1 in HSG and PC12 cells, which can be differentiated by laminin, but had no effect on MB-231, MDA-435, and PC-3 cells, which cannot be differentiated by laminin. In addition, we analyzed the expression level of the MT-1 gene in five prostate cancer cell lines possessing different metastatic potential. The expression of MT-1 in normal and less malignant cells (RWPE-1 and WPE1-NA22) was high and up-regulated by laminin, whereas the expression of MT-1 in WPE1-NB14, WPE1-NB11, and WPE1-NB26 cells (malignant) was extremely low and not elevated by laminin. These results suggest that the MT-1 gene is involved in laminin-mediated differentiation and affects the metastatic potential of tumor cells.

Lung cancer, breast cancer and lymphoma are the common oncologic causes of malignant pleural effusion, comprising more than the half of the causes. However, an endocrinologic carcinoma associated malignant effusion is very rare. Recently, we encountered a case of papillary thyroid carcinoma causing malignant effusion. An 83-year-old female patient presented with dyspnea due to massive pleural effusion in her left side. The pleural biopsy, pleural fluid cytology and breast needle aspiration biopsy results were consistent with a metastatic papillary thyroid carcinoma. Thyroid ultrasonography showed two thyroid masses, but the patient refused a thyroid biopsy. This case highlights the need for considering the possibility of papillary thyroid carcinoma when the cause of malignant pleural effusion cannot be found because one of the rare clinical manifestations of a papillary thyroid carcinoma can be dyspnea due to malignant effusion.

A gastrointestinal metastasis from lung cancer is rare and is quite often found during an autopsy. A 58-year-old man was admitted with left upper back pain and a mass in the left upper lobe on the chest radiograph. The transbronchial lung biopsy revealed an adenocarcinoma of the lung. A gastroduodenoscopy was carried out to evaluate the indigestion and epigastric discomfort. The duodenofibroscopy revealed bulging mucosa on the minor papilla of the duodenum. A metastasis to the duodenum from an adenocarcinoma of the lung was diagnosed by a duodenofibroscopic biopsy of the bulging lesion. We report this rare case of an adenocarcinoma of lung with a metastasis to the duodenum.

목적 : 국소 재발한 진행된 갑상선 유두암의 치료로 수술 후 외부방사선의 역할을 알아보고자 하였다. 대상 및 방법 : 원자력병원에서 2000년 1월부터 2012년 2월까지 사이버나이프 혹은 외부방사선 치료를 받은 수술과 방사선요오드 치료 후 국소 재발한 진행된 갑상선 유두암 환자 13 명을 대상으로 하였다. 경과관찰 기간 동안 국소 및 부위 재발이 발생환 환자는 6 명이었다. 몇몇의 위험인자를 찾기 위해서 Kaplan-Meier method와 log-rank test를 이용하여 성별, 종양단계, 방사선 치료 전 수술 횟수, 방사선요오드치료 횟수, 수술 후 잔존 암의 여부, 원격전이에 대해 단변량 분석하였다. 결과 : 방사선 치료 후 평균 추적관찰기관은 53.8개월(범위, 36 ~ 108개월)이고 그중 남자는 4 명이었다. 1년, 2년의 무진행 생존률은 각각 76.9와 53.8%였다. 단병량 분석은 성별과 잔존 암여부(p = 0.0475 and p = 0.0475, 각각)에 따라 무진행 생존률이 진행한 그룹과 진행하지 않은 그룹 사이에 유의한 차이가 있다는 것을 보여줬다. 결론 : 외부 방사선 치료 전에 잔존 암이 없었던 환자의 100%에서 국소 및 부위 재발이 일어나지 않았다. 외부방사선 치료는 수술과 방사선요오드 치료에 반응하지 않는 환자 중 수술 후 잔존 암이 없는 경우에 효과적인 치료 방법이 될 수 있다.

Objectives: This study was aimed to report a patient with metastatic pancreatic cancer treated with modified Bangam-tang and Gunchil-dan in conjunction with gemcitabine. There were better survival-related outcomes compared to gemcitabine alone. Methods: The patient with metastatic pancreatic cancer received gemcitabine as palliative chemotherapy since June 2016 concurrent with modified Bangam-tang and Gunchil-dan since October 2016 to October 2017. To evaluate the effect of treatment, tumor markers (carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA)), Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, and overall survival were checked. Adverse events were evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Results: After 12 months with the combination treatment, levels of CA19-9 were decreased from 8747 to 265.7 ng/ml and CEA from 42.2 to 6.5 U/ml. Clinical partial response state was shown until May 2, 2017 and stable disease state was maintained from August 4, 2017. In March 2018, the patient got an operation including pancreatectomy and diagnosed with no evidence of disease state in September, 2018. In conclusion, it showed the overall survival of 29 months from June, 2016 to November, 2018. Serious adverse events were not identified. Conclusions: This study suggested that combined treatment with modified Bangam-tang and Gunchil-dan may show better outcome in patient with metastatic pancreatic cancer than gemcitabine alone.

터널 발파시 발파효율은 암반의 특성에 큰 영향을 받기 때문에 암반 특성을 분석하고 이를 기초로 발파설계를 수행하는 것이 중요하다. 그럼에도 불구하고 현재까지 국내에서의 발파설계는 무결암의 단축압축강도만으로 발파암을 분류한 후 각 발파암의 발파계수를 구하는 방법을 이용하거나 공학적 암반분류법의 하나인 RMR 분류를 이용하여 발파암을 분류하되 객관적 근거가 미약한 경험적인 발파계수를 산정 하는 방식을 통하여 이루어졌다. 본 연구에서는 절리특성을 고려한 발파설계를 위하여 Ashby의 접근법을 활용하였다. 또한 절리조사 결과를 통한 발파암 분류방법과 발파패턴설계를 추가하여 발파설계 전 과정을 수행할 수 있도록 Ashby의 접근법을 응용하였다. 따라서 절리 분포 특성을 고려한 발파암 분류가 가능하고, 절리암반 특성을 고려한 발파설계를 수행할 수 있을 것으로 기대된다.

암이나 동맥경화는 활성산소가 우리 몸을 산화시켜 발생한다. 우리가 즐겨먹는 식품 가운데 활성산소를 제거해주는 식품은 많지만, 지금 전 세계적으로 가장 활발한 연구가 진행 되고 있는 식품이 바로 깨다. 연구 과정에서 항산화 물질인 세사미놀(sesaminol), 세사민(sesamine) 등의 기능이 계속 밝혀지고 있어 주목할 만한 항암 식품으로 떠오르고 있다.
