Simultaneous occurrence of medullary and papillary thyroid carcinomas in the same gland is very rare. In fact. there are only 18 cases of simultaneous occurrence of medullary and papillary thyroid carcinomas in the literature. We report a case of simultaneous medullary and papillary carcinoma of thyroid gland. A 67-year-old woman was diagnosed with medullary carcinoma of right lobe of thyroid gland and papillary carcinoma of left lobe of thyroid gland by fine needle aspiration cytology. Total thyroidectomy, anterior neck dissection, bilateral modified radical neck dissection and tracheotomy was undertaken. The tumor metastasized to regional lymph node and extrathyroidal muscle invasion of left papillary carcinoma was also revealed by pathological report. This report describes a case of thyroid carcinoma that demonstrated both medullary carcinoma and papillary components in the thyroid with lymph node metastasis.

Objectives : Well differentiated thyroid carcinoma(WDTC) has relatively good prognosis. But recurrence is associated with increased morbidity and mortality, and always results in reoperation. So it is important to evaluate the risk factors relative to the recurrence. The aim of this study is to evaluate the risk factors of recurrence. Materials and Method : Two hundred seventeen patients who had undergone thyroidectomy and proved as WDTC from January 1999 to December 2004 was included in the study. We reviewed patient-related and tumorrelated factors respectively and analyzed the correlation with tumor recurrence. Results : Fourteen patients from two hundreds seventeen had recurred. Recurrence rate was 6.5%, and average interval of recurrence was 28 month. Male, age over 45, multiple mass, and advanced TMN stage patient group show higher recurrence rate, but no statistical significance. However, the recurrence rate of lymph node metastasis, tumor size>1.5cm, and extracapsular invasion group were statistically high. Conclusion : Lymph node metastasis, tumor size and extracapsular invasion are significant risk factors related to the recurrence of WDTC.

This study was retrospectively reviewed and analysis of postoperative local complication on all patient undergoing thyroid operation of 242 cases of thyroid disease, at Department of General Surgery, Chosun University Hospital from January 1988 to December 1992. The result were follow: Postoperative local complication are as follow; 52 cases of transient hypocalcemia, 7 cases of thansient hoarseness, 3 cases of permanent hypocalcemia, 2 cases of permanent hoarseness, and other local complication were postoperative bleeding with airway obstraction, hematoma, infection. In pathologic classification according to complicative patients; The most common frequency of complication in benign disease was Graves' disease with 13 cases(54.2%), and the most frequency of complication in malignance disease was follicalar adenocarcinoma with 7 cases(53.9%). The frequency of complication according to operation procedure were unilateral lobectomy in 31 cases(19.9%), subtotal thyroidectomy in 15 cases(39.5%), near total thyroidectomy in 12 cases (44.4%), and total thyroidectomy in 10 cases(55.6%). There was a significant relationship between extent of operative procedure and frequency of complication. The incidence of local complication after thyroid resection was 57 of 196(29.1%) in the benign disease that was 15 of 26(57.7 %) in the intrathyroidal carcinoma and 13 of 20(65.0%) in the extrathyroidal carcinoma. There was significant different in frequency of local complication according to invasion and malignance of pathologic lesion. The most frequent complication after thyroid resection is transient hypocalcemia ; 39 of 196(19.9%) in the benign disease, 7 of 26(26.9%) in the intrathyroida1 carcinoma, and 6 of 10(30.0%) in the extrathyroidal carcinoma. Their complication rate increased in direct relationship to the invasion and malignance of pathologic lesion, but there was no statistically significant. Transient hypocalcemia was encountered in 52 cases of the total 242 patient(21.9%) ; 29 of 156(18.6%) after unilateral lobectomy, 9 of 38(23.7%) after subtotal thyroidectomy, and 5 of 18(27.8 %) after total thyroidectomy. The relation ship between temporal hypocalcemia and the extent of surgery was not statistically significant.

Purpose: To investigate the expression of Ki67 protein in papillary thyroid microcarcinoma(PTMC), and to analyze its clinical significance. Materials and Methods: Ki67 protein expression was evaluated in the tissues of 108 human PTMC and 50 other benign papillary hyperplasia of thyroid specimens using immunohistochemistry. Results: The expression intensity of Ki67 in PTMC and benign papillary hyperplasia of thyroid specimens were $1.45{\pm}1.83%$ and $0.46{\pm}0.46%$.The positive expression rates were 46.3% and 14%. There were significant differences between these two groups (p<0.01). There was no significant variation of the expression intensity and positive expression rates of Ki67 in PTMC with gender, age, position of the tumor and the level of TSH pre-operation (p>0.05), but these parameters varied with tumor size, invasion by membrane and cervical lymph node metastasis (p<0.05 or p<0.01). Conclusions: The expression of Ki67 in PTMC was related to tumor size, invasion by membrane and cervical lymph node metastasis, and could be the important indicator for judging clinical progress and estimating prognosis.

A 60 years old female patient presented with $8{\times}6\;cm$ sized painless oval mass in the left parietal region. She had left lobectomy of thyroid gland 10 years ago. Cranial CT, MRI, FGD PET-CT showed a solid mass which invaded left parietal bone. After embolization, craniectomy with tumor excision was performed. Histological examination revealed metastatic follicular cancer originated thyroid gland, with vascular and dura invasion. Postoperatively, neck CT showed right thyroid multiple nodules and right level III multiple lymph node enlargement. Thyroid function test was normal, but level of thyroglobulin was high (72ng/ml). So she had right lobectomy of thyroid gland with lymph node dissection under a diagnosis of follicular carcinoma. But histological examination revealed adenomatous hyperplasia and not lymph node metastasis. After operation, she received radioiodine therapy of 150mCi and then the level of thyroglobulin normalized (8.4ng/ml). The patient is under follow-up since she had operation 4 months ago.

Monoclonal antibody(TCM-9) against human thyroid cancers have been studied by screening with human thyroid cancers, normal and benign thyroid tissue, and normal human serum protein. A monoclonal antibody(TCM-9) that is known to have strong specificity for human thyroid cancer but not for Graves' disease, adenoma or normal thyroid does not bind to native or mature human thyroglobulin(Tg). We used to TCM-9 antibody by immunohistochemical staining on 5 follicular cancer, 2 follicular adenoma, 1 follicular neoplasm with suspicious invasion, 2 papillary cancer to ascertain being of help in differentiation between follicular carcinoma and adenoma. Reactivity of TCM-9 was observed in follicular carcinoma and papillary carcinoma but not observed in follicular adenoma. Thus TCM-9 is a novel monoclonal antibody against the thyroid cancer.

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer and current therapeutic strategies are limited in their effectiveness. The expressions of Rab5 and the M2 tumor-associated macrophage marker CD163 in tissues were detected by Western blot. The migration and invasion of cells were determined using a Transwell assay. The expressions of the exosome markers were evaluated by Western blot. The polarization of human macrophages (THP-1) was determined by incubation of THP-1 cells with conditioned medium or exosomes collected from MDA-MB-231 cells with indicated transfections or by a coculture system of THP-1 and MDA-MB-231 cells. The M1 and M2 macrophage markers were evaluated by qRT-PCR. The expression of Rab5 in TNBC was significantly higher than that in normal breast tissue. Rab5 expressions in triple-negative and luminal A breast cancer were higher than those in other molecular subtypes. Higher CD163 expression was observed in triple-negative breast cancer and in triple-negative and luminal B subtypes. Rab5 knockdown suppressed but Rab5 overexpression promoted the migration and invasion capacity of MDA-MB-231 cells. The levels of CD63 and CD9 in the medium of Rab5 knockdown cells were lower than those in control cells, whereas higher levels of CD63 and CD9 were observed in Rab5 overexpression cells. Rab5 knockdown decreased the excretion but did not alter the diameter of the exosomes. Knockdown of Rab5 facilitated the anti-tumor polarization of macrophages, which was partially reversed by Rab5 overexpression. Therefore, Rab5 is expected to be a potential therapeutic target for triple-negative breast cancer.
