We have experienced 5 cases of unusual well differentiated thyroid carcinoma with insular component during the past 5 years. 4 cases were presented with cervical masses but I case (patient 2.) was initiallty with lung and brain metastasis. The tumors from 4 cases showed invasive growths but that of 1 cases(patient 1.) showed intrathyroidal. Total thyroidectomy and cervical lymphnode dissection(CCND or RND) was performed in 4 cases but only RND was performed in spite of mediastinal metastasis of the tumor in patient 5 under the patient's choice. During the follow-up period, we also performed radical nephrectomy and metastatectomy for the kidney and iliac bone metastasis respectively, in patint 2. Microcsopically, the tumors showed the insular growth patterns, focally(less than 50%) in 3 cases and predominantly(more than 75%) in 2 cases. And the insular componentas were combined with papillary carcinoma in 2 cases and follicular carcinoma in 3 cases. Cervical lymphnode metastases were confirmed in 4 cases. Patient 2 died of disease with metastases to lung, brain, bone and kidney, 52 months after initial therapy. Patient 1, 3 and 4 are alive and have no recurrence and distant metastasis. Patient 5 is also alive with the mediastinal metastasis. In our experience, the well differentiated thyroid carcinomas with insular component showed characteristic histologic features, aggressive behavior in initial presentation and unfavorable prognosis regardless of the percentage of the insular component.

Purpose: The purpose of this study was to analyze clinical outcomes from cervical cancer and stratify patients into risk groups for prognostic factors for early-stage disease. Materials and Methods: We retrospectively reviewed patients with stage IB or IIA cervical cancer treated with adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT) following primary surgery at Samsung Medical Center from 2001 to 2011. Adjuvant RT was added for patients with intermediate-risk factors, and adjuvant CCRT was performed on high-risk patients after surgery. Results: We reviewed 247 patients-149 in the high-risk group and 98 in intermediate-risk group. The median follow-up was 62 months. Loco-regional failure (LRF) alone occurred in 7 patients (2.8%), distant metastasis alone in 37 patients (15.0%) and LRF with DM in 4 patients (1.6%). The 5-year disease-free survival (DFS) and overall survival (OS) rates for both groups were 79.7% and 87.6%, respectively. In the high-risk group, the 5-year DFS and OS probabilities were 72.5% and 81.9%, respectively. Histologic type, pathologic tumor size, and the number of pelvic lymph node (PLN) metastasis were significant prognostic factors for DFS and OS. We suggest a scoring system (0-3) using these prognostic factors to predict poor prognosis in high-risk patients. Using this system, patients with higher scores have higher recurrence and lower survival rates. Conclusion: In the high-risk cervical-cancer group who received primary surgery and adjuvant CCRT, non-squamous type, large tumor size and the number of PLN metastasis were significant prognostic factors, and the number of these factors was associated with survival rates.

It is well established that cervical lymph node metastasis is the base of clinical study on head and neck cancer. But few studies have been reported on lymph node metastasis of head and neck cancer in Korea. We consider it essential that studies on cervical lymph node metastases are conducted on pathologically proven database. Therefore, We must have database and consitent system for documentation and data collection of neck dissection specimen for prospective and retrospective study. Herein, We suggest several points from our experiences performing the proper data collection and documentation of neck dissection specimen.

This study was undertaken to compare surgical outcomes and survival rates of patients with the 2009 International Federation of Gynecology and Obstetrics (FIGO) stage IIA1 versus IIA2 cervical cancer treated with radical hysterectomy and pelvic lymphadenectomy (RHPL). Patients with stage IIA cervical cancer undergoing primary RHPL between January 2003 and December 2012 at Chiang Mai University Hospital were retrospectively reviewed. The analysis included clinicopathologic variables, i.e. nodal metastasis, parametrial involvement, positive surgical margins, deep stromal invasion (DSI)), lymph-vascular space invasion (LVSI), adjuvant treatment, and 5-year survival. The chi square test, Kaplan-Meier method and log-rank test were used for statistical analysis. During the study period, 133 women with stage IIA cervical cancer, 101 (75.9 %) stage IIA1, and 32 (24.1 %) stage IIA2 underwent RHPL. The clinicopathologic variables of stage IIA1 compared with stage IIA2 were as follows: nodal metastasis (38.6% vs 40.6%, p=0.84), parametrial involvement (10.9% vs 15.6%, p=0.47), positive surgical margins (31.7% vs 31.3%, p=1.0), DSI (39.6% vs 53.1%, p=0.18), LVSI (52.5% vs 71.9%, p=0.05) and adjuvant radiation (72.3% vs 84.4%, p=0.33). With a median follow-up of 60 months, the 5-year disease-free survival (84.6% vs 88.7%, p=0.67) and the 5-year overall survival (83.4% vs 90.0%, P=0.49) did not significantly differ between stage IIA1 and stage IIA2 cervical cancer. In conclusion, patients with stage IIA1 and stage IIA2 cervical cancer have comparable rates of locoregional spread and survival. The need for receiving adjuvant radiation was very high in both substages. The revised 2009 FIGO system did not demonstrate significant survival differences in stage IIA cervical cancer treated with radical hysterectomy. Concurrent chemoradiation should be considered a more suitable treatment for patients with stage IIA cervical cancer.

Purpose: Accurate evaluation of metastatic cervical lymph nodes plays a decisive role in the treatment and prognosis of patients with squamous cell carcinoma of the head and neck. The purpose of this study is to investigate the usefulness of FDG-PET for diagnosis of cervical metastasis in the head and neck cancer by comparing with the conventional imaging study. Materials and Methods: The subjects on this study were 30 patients (24 males and 6 females, aged 39 to 76, mean 57.1) diagnosed as pathologic-proven squamous cell carcinomas of the head and neck. All patients underwent preoperative FDG-PET, CT(n=27) or MRI (n=3). Their medical records were reviewed retrospectively. Using pathologic reports as a golden standard, the results of FDG-PET were compared with conventional imaging study (CT/MRI) in the evaluation of cervical metastasis. Results: Thirty patients had five different primary sites which were tongue (11), supraglottis (10), glottis (6), hypopharynx (2) and tonsil (1). A total of 40 neck dissections were performed unilaterally in 20 patients and bilaterally in 10 patients. Of these, 16 showed pathologically positive for lymph node metastasis. The sensitivity and specificity of FDG-PET for the diagnosis of cervical metastasis was 75% and 100% respectively, compared with conventional imaging of 56.3% and 95.8%, respectively. The difference of sensitivity was not statistically significant (p=0.453). Of 5 cases with small metastatic node (<1cm), 3 were detected on PET detected correctly but none were detected by CT. Conclusion: FDG-PET was more accurate than conventional imaging study in the diagnosis of metastatic lymph nodes in squamous cell carcinomas of the head and neck, especially detection of small metastatic node. FDG-PET might be useful adjunct to conventional image in the preoperative evaluation of head and neck squamous cell carcinoma.

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.

Purpose: To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Materials and Methods: Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. Results: The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. Conclusion: PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

Basal cell adenocarcinoma is a rare, recently described neoplasm of the salivary gland. We have experienced three cases of basal cell adenocarcinoma of the parotid gland. The tumors from patient 1 and patient 2 showed intraparotid growth in superficial lobe without cervical lymphnode metastasis. So, patient 1 and patient 2 underwent only a superficial parotidectomy and subdigastric lymphnode dissection without any adjuvant therapy. They are alive without recurrence or distant metastasis. But that of patient 3 showed widely invasive growth with multiple cervical lymph node metastases. The CT scan showed a $8{\times}7cm$ sized huge mass replacing the parotid gland with irregular margin and multiple lymphnode enlargements along the internal jugular vein. Total parotidectomy with sacrifying the facial nerve and standard radical neck dissection were caried out. Microscopically, the tumor consisted of solid nest and sheet of uniform basaloid cells separated by a fibrous connective tissue stroma with the evidence of lymphovascular invasion. As a result of the lymphnode metastasis and invasiveness of the tumor, radiation therapy was given postoperatively. We thought that close follow-up would be mandatory in this patient because of high risk of possible local recurrence and distant metastasis.

Lymph node metastasis from bladder cancer mainly involves the external/internal iliac and obturator nodes as the primary lymphatic drainage sites of the bladder, and common iliac sites as the secondary drainage. Lymph node involvement above the diaphragm is rare. Metastasis to the head and neck region is associated with poor prognosis and low survival rate. Herein, we report a case of cervical cutaneous and lymph node metastases in a patient with bladder cancer. This is a rare case of advanced urothelial carcinoma presenting as an aggressive inflammatory process with extensive lymph node involvement, without bony or visceral metastasis.

The purpose of this study is to report a case in which neoplasm metastases of cervical vertebrae were found in lung cancer patient during inpatient treatment for neck pain. Pain assessment and physical examination including numeral rating scale, range of motion of neck, Spurling's test, cervical compression test were performed. As a result, C-spine series X-ray was taken under the judgement it is not a simple neck pain. Bone metastases were suspected as X-ray showed loss of C7 left pedicle, indistinct C7 left transverse process and indistinct C4 upper margin. Magnetic resonance imaging and computed tomography were taken as further examination, and metastases of C4, C6, C7 were confirmed. The patient was transferred for professional treatment. In conclusion, this study shows the importance of appropriate diagnostic evaluation such as pain assessment and physical examination, and the need for diagnostic imaging in the treatment of patients with neoplasm history.
