Objectives: The object of this study was to observe antitumor, anticachexia and immunomodulatory effects of Shipyeukmiyeugi-eum(SYM) on human breast cancer cell, MCF-7, xenograft Balb/c nu-nu nude mice. Methods: Three different dosages of SYM-125, 250 and 500 mg/kg were orally administered once a day for 28 days from 11 days after tumor cell inoculation, and the changes on the body weights, tumor volume and weights, weights of spleen and popliteal lymph node and epididymal fat, serum IL-6 and IFN-${\gamma}$ levels, NK cell and peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were observed. In addition, histopathological observations of apoptotic cell, spleen, popliteal lymph node and cervical brown adipose were also detected. The results were compared with a potent cytotoxic estrogen receptor antagonist, Tamoxifen 20 mg/kg treated mice. Results: Tumor volumes and weights were decreased without cytotoxic effects on the both MCF-7 and MCF-10A cells as results of all three different dosages of SYM treatment. And weights of body, spleen, popliteal lymph node, epididymal fat, serum IFN-${\gamma}$, NK cell, peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were increased with decrease of serum IL-6. At histopathological observations, apoptotic tumor cells, spleen, popliteal lymph node and cervical brown adipose tissue were increased. That means tumor-related immunosuppress and cachexia were markedly inhibited by SYM treatment as compared with tumor-bearing mice. On the other hand, Tamoxifen showed marked cytotoxic effects against MCF-7 and MCF-10A, decreases of tumor volume and weights, and increases of apoptotic tumor cells and related decreases of tumor cell volumes, but tamoxifen markedly deteriorated the tumor-related immune-suppress and cachexia. Conclusions: The results obtained in this study suggest that SYM showed favorable anticancer effects and anticachexic effects on the MCF-7 cell xenograft through immunomodulatory effects. SYM did not induce any cytotoxic effects against both normal and cancer cells.

Objectives: The best treatment for the malignant parotid tumor still remains to be defined, and a better knowledge about the tumor features that predict the treatment result is needed. The aim of this study is to evaluate the treatment outcomes and to suggest the optimal treatment modality for the parotid cancer. Materials and Methods: The clinicopathologic characteristics of 113 patients who were treated for parotid cancer from January 1990 to December 2002 were retrospectively analysed. Univalate analyses were performed to establish the prognostic influence of pateint age, gender, tumor size, histologic grade and lymph node metastasis. Results: The mean age was 46.4 years old (15-81 years) and. The male to female ratio was 1 : 1.1. The chief complaint was a palpable mass in 85%, pain was in 12.4% and facial nerve palsy was accompanied with 2.7%. The mean tumor size was 3.5cm in diameter. The most common malignant tumor was mucoepidermoid carcinoma (33.6%), followed by acinic cell carcinoma (15%), adenoid cystic carcinoma (11%), carcinoma expleomorhpic adenoma (11%), basal cell carcinoma (7%). The most common operative procedure was total parotidectomy (47.8%) and various types of cervical lymph node dissection were added in 69.9%. Postoperative radiotherapy was done in 61.1 %. Postoperative complications developed in 54 cases (47.8%), including 46 cases (40.7%) of facial nerve palsy and 9 cases (8%) of Frey's syndrome. Recurrences developed in 21 cases (18.6%) and deaths in 15 (13.3%). Cumulative survival at 5 year was 75.4%. Univariate analysis of clinical factors showed that histologic grade and positive cervical lymph node significantly influenced survival (p<0.05). Conclusion: These results suggests that the radical resection with lymph node dissection and postopertaive XRT would be necessary to improve the survival of the patients with high grade cancer or positive lymphnode metastasis.

Metastasis from primary cancer to the thyroid is uncommon in breast cancer. Here we present a case of lobular breast carcinoma that metastasized to the thyroid. A 54-year-old woman without symptoms was admitted to our institution for staging of the lymph node above the left clavicle. An $^{18}F$-fluoro-deoxy-D-glucose positron emission tomography scan was performed for staging, and low uptakes were observed in the left supraclavicular and cervical lymph nodes. High uptake was seen in the posterior and lower left lobe of the thyroid. Histologic findings indicated lobular breast carcinoma (positive GATA3, loss of E-cadherin expression) metastatic to the thyroid with a luminal profile. Immunohistochemical analysis was negative for primary thyroid or parathyroid carcinoma. To our knowledge, this is the first report of a patient presenting a metastatic invasive lobular carcinoma in the thyroid and lymph nodes without a prior diagnosis of breast cancer.

Thyroid nodules are less common in children than in adults and their management is still controversial. The clinical presentations, operations, complications, histopathologic findings, and postoperative progressions of 34 pediatric patients that underwent thyroidectomy for palpable thyroid nodule at the Department of Surgery, Seoul National University Children Hospital between 1986 and 2003 were studied retrospectively by reviewing medical records and telephone interviews. The mean age of the patients was 11.8 years old. There were 23 females (67.6 %) and 11 males (32.4 %). Surgical indications were clinical need of histological confirmation (n=15), unresponsiveness to thyroxin replacement therapy (n=10), suggestion of the carcinoma on fine needle aspiration cytology (n=5), cosmetic purpose-a huge benign nodule (n=2), completion thyroidectomy for medullary thyroid carcinoma (n=1), and prophylactic thyroidectomy in a MENIIpatient (n=1). Unilateral Lobectomy was performed in 20 patients (57.1 %), subtotal thyroidectomy in 8 (22.9 %), total thyroidectomy in 5 (14.7 %), and completion thyroidectomy in 1 (2.9 %). Lymph node dissection was performed in 9 cases. Benign tumor was found in 23 patients (67.6 %), adenomatous goiter (n=18) and follicular adenoma (n=5). Malignant tumor was found in 11 children (32.4 %), 9 papillary carcinomas (26.5 %), and 2 medullary carcinomas (5.9 %). Of the 9 papillary carcinomas, 7 cases (77.8 %) had lymph node metastasis. No lymph node metastasis was found in 2 medullary carcinomas. Complications developed in 5 cases - transient hypocalcaemia (n=2), and temporary hoarseness (n=3). There was no mortality. Median follow-up period was 7.4 years (0.5-18 years). One patient showed recurrence in cervical lymph nodes 10 years after surgery and modified radical neck dissection was performed. Because of the high incidence of malignancy and advanced stage at initial presentation, more meticulous diagnostic work up is necessary for children with thyroid nodule, and more radical surgical treatment should be performed when malignant nodule is suggested.

Purpose: The diagnosis of Kawasaki disease depends on clinical symptoms, which makes it difficult to diagnose early in patients with only cervical lymphadenopathy. The purpose of this study is to understand the clinical characteristics of cervical-lymph-node-first presentation of Kawasaki disease and compare them with those of typical Kawasaki disease. Methods: We surveyed 283 patients who were admitted to Hallym Sacred Heart Hospital and were diagnosed with Kawasaki disease from January 2012 to December 2014. The patients were divided into two groups: cervical-lymph-node-first presentation of Kawasaki disease (LKD, N=24) and typical Kawasaki disease (KD, N=259). The medical records were retrospectively reviewed. Results: The mean age of the LKD group was higher than that of the KD group (P=0.04). At admission, the LKD patients had on average 1.62 out of 5 symptoms, whereas the KD patients had 3.47. The time from fever to diagnosis and administration of IV immunoglobulin was longer in the LKD group than in the KD group (P<0.001). The mean C-reactive protein of the LKD group was higher than that of the KD group (P=0.01). There were no statistical differences in the presence of coronary artery complications between the two groups at two weeks or at two months after diagnosis (P=0.52, P=0.08). Conclusions: The Kawasaki disease patients with fever and cervical lymphadenopathy usually do not present obvious clinical symptoms, which makes it hard to diagnose in the early phase of disease. Clinician must pay attention when examining these patients.

Background: This study was performed to evaluate their 5-year survival rates and identify the factors affecting the prognosis of oral cancer patients who had undergone surgical treatment only. Methods: Among 130 patients who were diagnosed with malignant tumor of oral, maxillofacial, and surgical treated in the Department of Oral and Maxillofacial Surgery at Chonnam National University Hospital within a period from January 2000 to December 2010, for 11 years, 84 patients were investigated who were followed up for more than 5 years after radical surgery; oral cancer is primary and received only surgical treatment. The survival rate according to gender, age, type and site of cancer, TNM stage, cervical lymph node metastasis and its stage, recurrence or metastasis, time of recurrence and metastasis, and differentiation were investigated and analyzed. Results: Overall, 5-year survival rate in patients who received only surgical treatment was 81.2 %, and disease-specific 5-year survival rate was 83.1 %. The disease-specific 5-year survival rate based on TNM stage, metastasis of cervical lymph node, N stage, and presence of recurrence/metastasis was a significant difference (p < 0.05). The disease-specific 5-year survival rate based on sex, age, type of tumor, primary site, and differentiation was not a significant difference (p > 0.05). Conclusions: These results suggest that good survival rate can be obtained with surgical treatment only, and stage of oral cancer, cervical lymph node metastasis and stage, recurrence or metastasis, time of recurrence, and metastasis have a significant effect on survival rate in oral cancer patients.

Objectives: The purpose of this study is to analyze clinical impact factors on the survival rate, and to acquire basic clinical data for the diagnosis of oral cancer, for a determination of the treatment plan with long-term survival in oral cancer patients. Materials and Methods: Through a retrospective review of the medical records, the factors for long-term survival rate were analyzed. Thirty-seven patients, among patient database with oral cancer treated in the Department of Oral and Maxillofacial Surgery at Pusan National University Hospital within a period from March 1998 to March 2008, were selected within the study criteria and were followed-up for more than 5 years. The analyzed factors were gender, age, drinking, smoking, primary tumor site, type of cancer, TNM stage, recurrence of affected region, and metastasis of cervical lymph node. The 5-year survival rate on the impact factors was calculated statistically using the Kaplan-Meier method. Results: By classification of clinical TNM at the 1st visit, there were 11 (29.7%) cases for stage I, 11 (29.7%) cases for stage II, 3 (8.1%) cases for stage III, and 12 (32.5%) cases for stage IV. The 5-year survival rate of total oral cancer patients after the operation were 75.7%, pathological TNM stage related 5-year survival rate were as follows: stage I 90.0%, stage II 81.8%, stage III 100% and stage IV 45.5%; in which the survival rate difference by each stage was significantly observed. The recurrence of cervical lymph node was the significant impact factor for the survival rate, because only 30.0% the survival rate in recurrent cases existed. During the follow-up, there were 15 (40.5%) patients with confirmed recurrence, and the 5-year survival rate of these patients was decreased as 46.7%. Conclusion: The classification of clinical and pathological TNM stage, local recurrence after surgery, and metastasis of cervical lymph node after surgery were analyzed as the 3 most significant factors.

Background: Positive para-aortic lymph node (PALN) at diagnosis in cervical cancer patients confers an unfavorable prognosis. This study reviewed the outcomes of extended field radiotherapy (EFRT) and concurrent chemotherapy with extended field RT (CCEFRT) in patients with positive PALN at diagnosis. Materials and Methods: Medical records of 407 cervical cancer patients between 1st January 2002 to 31st December 2012 were reviewed. Some 32 cases with positive PALN were identified to have received definitive extended field radiotherapy with or without chemotherapy. Treatment outcomes, clinicopathological factors affecting survival and radiotherapy related acute and late effects were analyzed. Results: Totals of 13 and 19 patients underwent EFRT and CCEFRT respectively during the period of review. The median follow-up was 70 months. The 5-year overall survival (OS) was 40% for patients who underwent CCEFRT as compared to 18% for patients who had EFRT alone, with median survival sof 29 months and 13 months, respectively. The 5-years progression free survival (PFS) for patients who underwent CCEFRT was 32% and 18% for those who had EFRT. Median PFS were 18 months and 12 months, respectively. Overall treatment time (OTT) less than 8 weeks reduced risk of death by 81% (HR=0.19). Acute side effects were documented in 69.7% and 89.5% of patients who underwent EFRT and CCEFRT, respectively. Four patients (12.5%) developed radiotherapy late toxicity and there was no treatment-related death observed. Conclusions: CCEFRT is associated with higher 5-years OS and median OS compared to EFRT and with tolerable level of acute and late toxicities in selected patients with cervical cancer and PALN metastasis.

Purpose: To evaluate the diagnostic accuracy of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography/computed tomography (PET/CT) in predicting pelvic lymph node (LN) metastases in patients with cervical cancer. Materials and Methods: From January 2009 to March 2015, 114 patients with FIGO stage IA1-IIB uterine cervical cancer who underwent hysterectomy with pelvic lymphadenectomy and took CT, MRI, and PET/CT before surgery were enrolled in this study. The criteria for LN metastases were a LN diameter ${\geq}1.0cm$ and/or the presence of central necrosis on CT, a LN diameter ${\geq}1.0cm$ on MRI, and a focally increased FDG uptake on PET/CT. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for pelvic LN metastases were estimated. Results: The sensitivity, specificity, PPV, NPV, and accuracy for detection of pelvic LN metastases were 51.4%, 85.9%, 41.3%, 90.1%, and 80.3% for CT; 24.3%, 96.3%, 56.3%, 86.8%, and 84.6% for MRI; and 48.6%, 89.5%, 47.4%, 90.0%, and 82.9% for PET/CT, respectively. The sensitivity of PET/CT and CT was higher than that of MRI (p=0.004 and p= 0.013, respectively). The specificity of MRI was higher than those of PET/CT and CT (p=0.002 and p=0.001, respectively). The difference of specificity between PET/CT and CT was not statistically significant (p=0.167). Conclusion: These results indicate that preoperative CT, MRI, and PET/CT showed low to moderate sensitivity and PPV, and moderate to high specificity, NPV, and accuracy. More efforts are necessary to improve sensitivity of imaging modalities in order to predict pelvic LN metastases.

Purpose: Several studies report that detection of thyroglobulin (Tg) in fine-needle aspiration (FNA) biopsy washout fluid from lymph nodes identifies recurrences or metastases of differentiated papillary thyroid cancer (DPTC) in the neck with higher sensitivity and specificity than fine-needle aspiration cytology (FNAC). We evaluate the diagnostic efficacy and usefulness of Tg measurement in FNA washout fluid (FNA-Tg) and compare with FNAC. Materials and Methods: Forty-eight FNA samples of 37 patients who undergone ultrasonography to detect cervical lymph node metastasis of DPTC, were included for this study. Lymph node metastasis was confirmed by histopathologic examination or long-term imaging follow-up. Sensitivity, specificity and accuracy of FNA-Tg and FNAC were calculated. In 34 patients, we evaluated diagnostic accuracy of FNA-Tg according to the presence or absence of Tg antibody. Results: Sensitivity, specificity and accuracy of FNAC were 75.0%, 97.2% and 91.7%, respectively, and those of FNA-Tg were 100%, 88.9% and 91.7%, respectively. The presence of Tg antibody was not relevant to the diagnostic accuracy of FNA-Tg. Conclusion: FNA-Tg is a as accurate as FNAC with higher sensitivity. FNA-Tg and FNAC are complement techniques for diagnosing lymph node metastasis of DTPC.
