Cystic metastasis in the neck from pharyngeal cancer has often been mistaken for either primary squamous cell carcinoma of branchiogenic origin or branchial cleft cyst. The distinctive histological and clinical features of cystic metastasis reviewed after its correct indentification can lead to the discovery of an unsuspected primary lesion and result in specific treatment options. Recendy, the authors experienced three cases of cystic metastasis in the neck from pharyngeal cancer ; one was from nasopharyngeal squamous cell carcinoma and the other two were from tonsillar squamous cell carcinomas. This report summarizes our experiences and review of the literatures.

Purpose: The common features of brain metastases from gastric cancer are unknown because brain metastasis is an uncommon pattern of metastasis. The purpose of this study was to investigate the clinical features of and the prognosis for patients with brain metastases after a curative resection for gastric cancer. Materials and Methods: Twenty-one (21) cases of patients with brain metastases of gastric cancer, who had been treated at the Department of Surgery, Yonsei University College of Medicine, were assessed retrospectively. Results: The mean age was $55.8\pm9.6$ years (range: $34\~70$ years), and the male-to-female ratio was 2.5 : .1. The most common neurologic symptom was headache ($38.5\%$), and no patient was free from the neurologic symptoms. The incidence of parenchymal metastasis (PM: $76.2\%$) was higher than that of leptomeningeal metastasis (LM: $19.0\%$). Patients with gastric cancer and brain metastasis showed high rates of blood and lymphatic vessel invasion (lymphatic vessel invasion: $85.7\%$; blood vessel invasion: $80.9\%$). According to Lauren's classification, the incidence of intestinal types was 14/21 ($66.7\%$), that of diffuse types was 3/21 ($14.3\%$) and that of mixed types was 4/21 ($19.0\%$). The mean interval between the gastrectomy and the diagnosis of brain metastasis was $24.7\pm4.0$ months (PM: 26.8 months; LM: 20.3 months). The median period of survival after diagnosis of brain metastasis was 2 months for paren chymal metastasis and 0 months for leptomeningeal metastasis. Conclusion:.. During a follow-up period, patients with neurologic symptoms should be suspected of having brain metastasis. Early diagnosis and treatment is the only hope to prolong survival in such patients.

Many types of cancer, current therapy other than surgery and/or radiotherapy was of only limited efficacy. At the basic chinese traditional medicine(TCM) there was increased understanding of the additional basic and clinical neoplasm treatment research. The metastasis and recurrence of neoplasm was the basis of yudu(餘毒) on remained neoplasm cell and stagnation of blood, thermotoxo, phlegm, asthenia of healthy enerngy, stagnation of vital energy. The principles therapy of neoplasm on metastasis and recurrence was based on knowledge of the method of support the healthy energy and strengthen the body resistance, promote blood circulation to remove blood stasis, clear away heat and toxic materials, dissipate phlegm and disperse the accumulation of evils, regulate vital energy and disperse the depressed vital energy. But the major clinical features of neoplasm was to be considered in developing a treatment plan include (1) distinguish between clinical and pathologic staging - acute and chronic, (2) classification of pathologic pattern, and (3) distinction of body situation : for examples asthenia - sthenia etc. It was most important to distinguish between supporting the healthy and eliminating the evil factors and to treat differently at the root and the branch cause of a neoplasm. This paper's results indicate that identification and effective use of TCM medicines inhibited netastasis and decreased recurrence and then we were able to expect increasing survival rate.

Mutation of the P53 tumor suppressor gene playa major role in the development of many carcinomas, namely in the colon, breast and bladder, whereas the role played by such mutations in thyroid carcinogenesis remains controversial. Vascular endothelial growth factor (VEGF) induces proliferation of endothelial cells, stimulates angiogenesis, and increases vascular permeability. Increased VEGF expression has been associated with poor clinical outcomes in many malignancies E-cadherin, a calcium-dependent transmembrane glycoprotein, is an adhesion molecule Expression of p53, VEGF and E-cadherin was assessed immunohistochemically in 19 tall columnar variant of papillary carcinoma, 24 common papillary carcinoma and 7 follicular carcinoma. The aim of this study was to evaluate the expression of P53,VEGF and E-cadherin as a potential maker for the prognosis of thyroid carcinomas. The results are as follows: 1) There were no significance in any clinical parameters examined among tall columnar variant of papillary carcinoma, common papillary carcinoma and follicular carcinoma. 2) The expression of P53 demonstrated low in tall columnar variant of papillary carcinoma, common papillary carcinoma and follicular carcinoma, but a significantly high in regional lymph node metastasis. 3) The expression of VEGF demonstrated a significantly high in regional lymph node metastasis than those without metastasis in papillary thyroid carcinoma. 4) The expression of E-cadherin demonstrated less often among papillary carcinomas with lymph node metastasis than in those without metastasis in papillary thyroid carcinoma. In conclusion, it is suggested that VEGF and E-cadherin will be useful for the diagnosis of thyroid carcinoma and serves as a biological marker for thyroid carcinoma lymph node metastasis.

Follicular thyroid carcinoma (FTC) is the second most common thyroid cancer, following papillary carcinoma. Metastasis to the orbital rim from FTC is very rare. We recently experienced a case of FTC with metastasis to the orbital rim in a 74-year-old woman, who initially presented with a huge thyroid mass and an asymptomatic solitary orbital rim lesion. The solitary orbital rim lesion was suspected to be a separate disease entity such as lymphoma from the preoperative imaging, but bone metastasis from FTC was finally confirmed after orbital rim resection and total thyroidectomy. During follow-up, the patient presented multiple bone metastasis, so the solitary orbital rim lesion was considered a clinical sign of systemic metastasis from FTC. Therefore, we present this unique case with a review of the literature.

Objective: To evaluate the safety and efficacy of sequential transcatheter arterial chemoembolization (TACE) and portal vein embolization (PVE) before major hepatectomy for patients with hepatocellur carcinoma (HCC). Methods: In this retrospective case-control study, data were collected from patients who underwent sequential TACE and PVE prior to major hemihepactectomy. Liver volumes were measured by computed tomography volumetry before TACE, and preoperation to assess degree of future remnant liver (FRL) hypertrophy and to check whether intro- or extrohepatic metastasis existed. Liver function was monitored by biochemistry after TACE, prior to and after major hepatectomy. Results: Mean average FRL volume increased 32.3-71.4% (mean 55.4%) compared with preoperative FRL volume. After TACE, liver enzymes were elevated, but returned to normal in four weeks. During PVE and resection, no patient had intro- or extrohepatic metastasis. Conclusion: Sequential TACE and PVE is an effective method to improve resection opportunity, expand the scope of surgical resection, and greatly reduce postoperative intra- and extrahepatic metastasis.

Background: This study aimed to determine the utility and a cut-off level of serum squamous cell carcinoma antigen (SCC-Ag) to predict lymph node metastasis in locally advanced cervical cancer cases. We also investigated the correlation between SCC-Ag level and lymph node status. Materials and Methods: From June 2009 to June 2014, 232 patients with cervical cancer stage IB2-IVA, who were treated at Ramathibodi Hospital, were recruited. Receiver operating characteristic (ROC) curves were used to identify the best cut-off point of SCC-Ag level to predict lymph node metastasis. Quantile regression was performed to evaluate the correlation between SCC-Ag levels and pelvic lymph node metastasis, paraaortic lymph node metastasis, and parametrial involvement as well as tumor size. Results: Pelvic lymph node metastasis and paraaortic lymph node metastasis were diagnosed in 46.6% and 20.1% of the patients, respectively. The median SCC-Ag level was 6 ng/mL (range, 0.5 to 464.6 ng/mL). The areas under ROC curves between SCC-Ag level and pelvic lymph node metastasis, paraaotic lymph node metastasis, parametrial involvements were low. SCC-Ag level was significantly correlated with paraaortic lymph node status (p=0.045) but not with pelvic lymph node status and parametrial involvement. SCC-Ag level was also related to the tumor diameter (p<0.05). Conclusions: SCC-Ag level is not a good predictor for pelvic and paraaortic lymph node metastasis. However, it is still beneficial to assess the tumor burden of squamous cell carcinoma of the cervix.

배 경 : 폐는 악성 종양이 흔히 전이되는 장소로 흔히 폐실질, 흉막, 혹은 임파선으로 주로 전이되며, 기관지내 전이는 흔하지 않아 악성 종양의 기관지내 발생율은 2%정도로 알려져 있다. 저자들은 굴곡성 기관지경 검사로 확인된 증례들을 대상으로 기관지내 전이암에 대한 임상적 특징을 알아보고자 하였다. 연구방법 : 1991년 6월부터 2001년 5월까지 10년 동안 연세대학교 의과대학 세브란스병원에서 굴곡성 기관지경 검사로 폐외 악성 종양의 기관지내 전이가 확인된 27예를 대상으로 임상 양상, 치료, 경과 등을 조사하였다. 연구결과 : 평균연령은 53세이고, 남자가 17예, 여자가 10예이었다. 원발 종양은 대장암이 가장 많았으며, 자궁경부암, 위암, 유방암의 순서이었다. 원발 종양의 진단에서부터 기관지내 전이를 발견할 때까지의 기간은 평균 45.5개월이었으며, 유방암이 85.3개월로 다른 종양들에 비해 길었다. 임상 증상은 기침이 가장 많았고, 흉부 X-선 소견은 폐문부 종괴음영, 단일결절, 무기폐가 많았다. 치료는 수술, 항암 화학요법, 방사선치료 등을 시행하였고, 생존기은 평균 12.3개월이었다. 결 론 : 기관지내 전이암은 임상에서 흔한 질환이 아니며, 증상, 방사선 소견, 기관지경 소견 등이 원발성 폐암과 유사하다. 따라서 악성 종양의 병력이 있으면서 지속적인 증상이 있거나 비전형적인 병리소견을 보일 때에는 기관지내 전이암의 가능성을 염두에 두고 접근하여야 한다.

Early diagnosis, accurate assessment, and localization of peritoneal metastasis (PM) are essential for the selection of appropriate treatments and surgical guidance. However, available imaging modalities (computed tomography [CT], conventional magnetic resonance imaging [MRI], and 18fluorodeoxyglucose positron emission tomography [PET]/CT) have limitations. The advent of new imaging techniques and novel molecular imaging agents have revealed molecular processes in the tumor microenvironment as an application for the early diagnosis and assessment of PM as well as real-time guided surgical resection, which has changed clinical management. In contrast to clinical imaging, which is purely qualitative and subjective for interpreting macroscopic structures, radiomics and artificial intelligence (AI) capitalize on high-dimensional numerical data from images that may reflect tumor pathophysiology. A predictive model can be used to predict the occurrence, recurrence, and prognosis of PM, thereby avoiding unnecessary exploratory surgeries. This review summarizes the role and status of different imaging techniques, especially new imaging strategies such as spectral photon-counting CT, fibroblast activation protein inhibitor (FAPI) PET/CT, near-infrared fluorescence imaging, and PET/MRI, for early diagnosis, assessment of surgical indications, and recurrence monitoring in patients with PM. The clinical applications, limitations, and solutions for fluorescence imaging, radiomics, and AI are also discussed.
