Surgery, radioiodine therapy, and thyroxine treatment represent established therapeutic measures of proven efficacy for the treatment of well-differentiated thyroid cancer. However, in some cases, dedifferentiation is noted and it makes tumors refractory to conventional treatment. Recently, retinoic acid redifferentiation therapy was evaluated in several in vitro and in vivo studios. We report a patient with papillary carcinoma in whom metastatic lesions became radioiodine negative on high-dose therapy. Redifferentiation therapy with retinoic acid induced radioiodine uptake in some of metastatic tissues. Side effects such as xerostomia and cheilosis were mild. We recommend retinoic acid redifferentiation therapy as an option for the treatment of thyroid cancer with negative radioiodine uptake after high-dose radioiodine therapy.

Objectives: This study assessed the effect of a combination of Korean medicine and immunotherapy on three papillary thyroid cancer patients following thyroidectomy. Methods: The three patients who underwent thyroidectomy received Korean medical treatments, including acupuncture, moxibustion, pharmacopuncture, and immunotherapy. To evaluate the patients, symptoms were measured using the Numerical Rating Scale (NRS) and Karnofsky Performance Status Scale (KPS). Blood tests, including thyroid function tests, were conducted during treatment. Results: After treatment, postoperative pain and general weakness were gradually alleviated. Conclusions: These cases provide evidence that treatment with a combination of Korean medicine and immunotherapy can have substantial benefits for postoperative complications following thyroidectomy.

Background and Objectives: National cancer center institute reports that male patients of papillary thyroid carcinoma (PTC) are annually increasing. This study aimed to analyze the features of the male patients with PTC. Materials and Method: We retrospectively reviewed and analyzed clinical records of 170 patients who were treated for PTC in male patients between 2000 and 2010. Clinical features, size, pathologic type, extrathyroidal extension, recurrence, multiplicity, extent of surgery, and lymph node metastasis were retrospectively evaluated.Univariate and multivariate analyses of various clinical factors were performed. Results: Total 4145 patients received surgery for papillary thyroid carcinoma. The number of male patients was 170 (4.1%) among them. Of170 male patients, only 16(9.4%) patients underwent the recurrence of PTC. The size of tumor, central neck node metastasis, lateral neck node metastasis, extrathyroidal extension and RAI ablation therapy were associated with recurrence(p< 0.05) in univariate analysis. However, only the extrathyroidal extension [p=0.03, Odds ratio=3.58(95% CI. 1.09~14.24)] was related to the recurrence in multivariate analysis. Conclusion: Re-estimation of clinical features in male PTC patients should be concerned. The recurrence of PTC in male patients was 16(9.4%) and nearly same as the other studies. The extrathyroidal extension was revealed as an associated factor for the recurrence. Evaluation of regional or distant metastasis should be considered in patients with the extrathyroidal extension in male PTC patients during long-term follow-up.

Objectives : Thyroid cancer is one of the most common and rapid increases of malignancy worldwide. It is the aim of the present a case of papillary thyroid microcarcinoma (PTMC) treated with acupuncture alone to derive further studies of the determination of treatment options for PTMC, such as surgery, acupuncture and observation alone, etc. Method : A 51-year-old woman with malignancy of thyroid nodule ($0.89{\times}0.59cm$) was referred to our hospital on January 2010. We applied to the acupuncture alone three times weekly by the patient's decision from January 2010 to November 2014. Blood tests were conducted three times during the treatment period and ultrasonography was performed every 6 months. Results : Both laboratory data and tumor size results showed no deteriorations as compared with those of initial examination. The patients has been survived in healthy state without any metastasis or disease progression on November, 2014. Conclusion : This case presents a possibility that acupuncture or observation alone can be provided as an option in the treatment means for patients with PTMC. Further study will need to study more longer follow-up and a large number of patients for PTMC using acupuncture or observation alone.

Objectives: The tall cell variant is an uncommon variant and has been known as more aggressive form of papillary thyroid carcinoma (PTC). Owing to the rarity of these thyroid cancers, their clinical behavior remains incompletely understood. To elucidate the clinicopathologic characteristics of tall cell variant, we retrospectively reviewed our surgical experience of patients with tall cell variant. Methods: Between August 1993 and July 2004, a total of 11 consecutive patients who were pathologically diagnosed with tall cell variant of papillary thyroid carcinoma were enrolled in this study. All patients underwent total (8 cases) or subtotal thyroidectomy (3 cases) with central compartment node dissections. The lateral neck dissection was added in 6 patients. After the operation, neck ultrasound and serum thyroglobulin were checked regularly during the follow-up period. Results: The mean age of the patients was 56.6years (range, 30-74years) at the time of diagnosis. 3 patients were men, and 8 were women. The mean diameter of tumor was 3.7cm(range, 1.5-6.0cm), and 6 patients had lateral neck node metastasis. Extrathyroidal extension was seen in 5 patients (45%). Loco-regional recurrence was found in 2 patients (18%), and distant metastasis in 1 patient (9%). The 5-year disease free survival rate was 68%. Conclusion: The tall cell variant of papillary thyroid carcinoma is an uncommon disease. Clinicopathologic feature and prognosis of this disease show more aggressive behaviors than ordinary papillary thyroid carcinoma. More aggressive treatment and close follow-up should be undertaken in the tall cell variant of papillary thyroid carcinoma.

Cystic parathyroid adenoma is one of rare causes of hyperparathyroidism, and tends to cause increased serum level of parathyroid hormone, alkaline phosphate and serum calcium level similar to when compared to those of solid adenoma. The possibility of a coincidental appearance of primary hyperparathyrodism and nonmedullary thyroid cancer is rare, and often neglected. A 40-year-old female presented with constipation and weight loss for 3 months. The serum calcium, phosphate and alkaline phosphate were 16.6 mg/dl, 2.2 mg/dl and 505 IU/L respectively and serum parathyroid hormone level was 1556.2 pg/mL. Neck US showed mixed nodules at both thyroid lobes, and PET-CT showed a right thyroid nodule without FDG uptake. The patient was diagnosed of primary hyperparathyroidism and underwent parathyroidectomy and a total thyroidectomy. Histopathologic results revealed parathyroid adenoma with cystic change (2 cm greater diameter) in the right lower parathyroid gland and coexistent papillary carcinoma of the right lobe of thyroid gland (infiltrating, 0.3 cm in greater diameter). She remained well and serum calcium, phosphate, parathyroid hormone level were normalized within 24 hours.

Objective: The nm23 gene has been identified as a potential metastasis suppressor gene in various human neoplasms. Both Bcl-2, which promotes cell survival, and Bax, which promotes cell death, have been considered as major factors in controlling the apoptotic pathway. This study was carried out to determine whether these markers are useful in distinguishing potential intrinsic differences in tumor virulence of papillary thyroid cancers. Material and Method: The expressions of nm23, Bcl-2 and Bax have been evaluated using immunohistochemical techniques in 100 pure papillary thyroid cancers and 20 metastatic lymphnodes. The intensity of immnunoreactivity was graded on arbitrary four point scale(grade 0 or 1 : negative reactivity, grade 2 or 3 positive reactivity). The immunoreactivities were analyzed in relation to TNM atage, AMES score, local recurrence and distant metastasis, and that of metastatic LNs was compared with the tumors. Results: The expression of Bcl-2 and bax did not show any statistical differences by TNM stage, AMES score, recurrence, distant metastasis and also between the tumor and metastatic LN. However, the nm23 showed higher expression of Ki67 in distant metastasis than in control group and in metastatic LNs than in the tumors(p<0.05). Conclusion: Although the expression of Bcl-2 and Bax protein showed no correlation with clinical parameters representing tumor virulence, the nm23 expression could be an useful prognostic factor, especially in predicting nodal or distant metastasis in papillary thyroid cancer.

Thyroid carcinomas are usually classified as papillary thyroid carcinoma, follicular thyroid carcinoma, medullary thyroid carcinoma and anaplastic thyroid carcinoma. Among the thyroid carcinomas, the incidence of medullary and anaplastic thyroid carcinoma is low, but the rate of lymph node & distant metastasis from them are more common compared to other types. Follicular thyroid carcinoma has a low rate of lymph node metastasis as 10% and has a high occurrence of hematogenous metastasis to lung, bone, brain and liver. Papillary thyroid carcinoma accounts for $60{\sim}70%$ of whole thyroid carcinomas and the cervical lymph node metastasis is $21{\sim}81%$ including micrometastasis, but the distant metastasis is rare. In the case of bone metastasis, follicular type reveals most frequent, and the rate is about 5%, and more likely to be found on vertebra, pelvis, ribs, femur, and skull. The clinical symptoms of bone metastasis are pain, swelling, pathological fracture and radiologically osteolytic lesions can be observed. But distant metastasis of papillary thyroid carcinoma is very rare and especially, bone metastasis has hardly been reported. The treatment modalities of metastatic thyroid carcinoma to mandible are known as follows : thyroidectomy to treat primary site, resection of the affected site of mandible, external beam radiotherapy and radioiodine therapy etc.

Papillary thyroid carcinoma is the most common type of thyroid malignancy. It has better prognosis and rarer incidence of distant metastasis than other types of thyroid malignancy. However, once distant metastasis happens, its result will be bad. They mostly spread to the lungs and bones. and rarely to the brain. We report a patient with a papillary thyroid carcinoma metastasis to the lymph nodes. the ribs. the brain, and the lungs. The patient underwent total thyroidectomy, radioiodine ablation, rib partial resection, and lung wedge resection. However, upon progress of metastasis. the patient insisted on being treated with traditional Korean medical treatment using allergen-removed Rhus Verniciflua Stokes (A-RVS) instead of the conventional treatment including chemotherapy. The size of the tumor partly decreased, and the patient showed no side effects. This case report brings forth the importance of a thorough study in papillary thyroid carcinomas and their metastasis from the traditional Korean medical point of view, along with the long-term effect of allergen-removed Rhus Verniciflua Stokes (A-RVS).

The papillary carcinoma is the most common malignant neoplasm of thyroid gland and the prognosis is better than anyother type of thyroid carcinoma. However, the thyroid is closed to the important organs such as esophagus, trachea and larynx, there are some possibilities to invade these organs. In case of advanced disease, not only surrounding structures but also mediastinum and cervical lymphatic chain can be involved or distant metastasis develops frequently. Therefore in these cases the prognosis is worse and the rate of inoperable case is more than those of non-metastatic group. Generally, the treatment modality for papillary thyroid carcinoma consists of surgery, postoperative thyroid hormone and radioiodine therapy. If the tumor invades surrounding structures, cervical lymph node or mediastinum, total thyroidectomy and wide excision of tumor invaded area including mediastinal dissection and neck dissection is necessary. Recently, the authors have experienced a case of locally invasive and recurred papillary thyroid carcinoma without treatment for 7 years. The patient was performed previously thyroid lobectomy and isthmusectomy 13 years ago. We had determinded surgical therapy for this patient and performed mass excision with overlying skin, completion total thyroidectomy, right type I modified radical neck dissection, left lateral neck dissection, thoracotomy with supramediastinal dissection, shaving of diffusely involved trachea and skin defect reconstruction with pectoralis major myocutaneous flap. After operation 2 cycles of radioiodine therapy were taken. Now the patient is following up at the outpatient base and no evidence of disease state for postoperative 16 months. So we report on this case with a brief review of literature.
