Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid cancer. Therefore, laparoscopic distal gastrectomy with lymph node dissection and left thyroidectomy were performed. On the basis of the pathologic findings of the surgical specimens, the patient was diagnosed to have papillary thyroid microcarcinoma with perigastric lymph node metastasis and early gastric cancer with mucosal invasion. Finally, on the basis of immunohistochemical staining with galectin-3, the diagnosis of perigastric lymph node metastasis from PTC was made. When a patient has multiple primary malignancies with lymph node metastasis, careful pathologic examination of the surgical specimen is necessary; immunohistochemical staining may be helpful in determining the primary origin of lymph node metastasis.

Aims: To explore the relationship between various molecular makers and liver metastasis of colorectal cancer (CRC). Method: Using immunohistochemistry, protein expression of CEA, nm23, c-met, MMP2, COX-2, VEGF, EGFR, and CD44 was assessed in 80 CRC cases. The Chi-square test and logistic regression were performed to analyze the relationship between these indicators and CRC liver metastasis. Results: There were significant differences in expression of CEA, MMP2, CD44, VEGF and EGFR between the liver metastasis and non metastasis groups (P < 0.05); no significant differences were noted for nm23, c-met, and COX-2 expression. Logistic regression analysis showed that only CEA, VEGF, and EGFR entered into the regression equation, and had significant correlations with CRC liver metastasis (${\alpha}$ inclusion= 0.10, ${\alpha}$ elimination = 0.15, R2 = 0.718). Conclusions: Combination detection of CEA, VEGF, and EGFR may be an effective means to predict CRC liver metastasis. Nm23, c-met, MMP2, COX-2, and CD44, in contrast, are not suitable as prognostic markers.

Purpose: This study was a retrospective analysis with survey study which analyze influence of depression of patients with cancer on metastasis. Methods: The subjects of this research were 223 patients who underwent chemotherapy or are in follow-up management with stomach, colon, or breast cancer. The questionnaires were collected in 2002 and medical documents were reviewed 400 days after the first data collection. Subjects were divided according to the depression level into over-average group and under average group. Results: In survival analysis, metastasis occurred in 49 of 211 in 223 subjects for whom follow-up review was done after 400 days. The depression and anxiety level were higher in the group with metastasis than the other with no metastasis. As a result, it showed that the lower depression they have, the lesser the metastasis occurred. Conclusion: This research showed that patients who have higher level of depression, experienced higher risk for cancer metastasis. Nurses who take care of cancer patients are responsible for giving patients with positivity with intention to subside their depression.

The effect of methamphetamine on the pulmonary metastasis was investigated in C57BL/6 mice injected with Bl6 melanoma cells. Bl6 melanoma cells (2$\times$10$^{5}$ cells) were injected intravenously into 5~7 weeks old C57BL/6 mice. Mice were then treated intraperitoneally with methamphetamine either acutely (two times with one week interval) or subchronically (daily for 14 days). Degree of pulmonary metastasis was investigated and specific immunologic parameters such as natural killer cell cytotoxicity(NKCC), antibody-dependent cellular cytotoxicity(ADCC) and blastogenic responses of splenocytes were examined. Mice which had been subchronically treated with methamphetamine showed significant decreases in the number of pulmonary metastasis of Bl6 melanoma cells, NKCC and ADCC without a significant change in blastogenic responses. In the acutely-treated group, slight trends of decrease in the numbers of pulmonary metastasis, NKCC and ADCC were observed without statistical significances whereas there was a significant increase in blastogenic responses. The mechanism underlying the decrease in the degree of metastasis despite diminished NKCC and ADCC after methamphetamine treatment and the relationship between the degree of pulmonary metastasis and duration of methamphetamine treatment remain to be investigated.

Background: To determine survival times of cervical cancer patients with bone metastasis related to the effect of age at the time of cervical cancer diagnosis, we performed the retrospectively analytical study. Methods: A total of 68 cervical cancer patients with bone metastasis were treated at a single hospital, during January 1998 to December 2010. Fifty-two medical records were identified and collected, the remaining sixteen medical records were not found. Main outcome measures were patient characteristics, clinical information, duration from cervical cancer diagnosis to bone metastasis diagnosis, survival time after bone metastasis and overall survival time. Results: Among fifty-two cervical cancer patients with bone metastasis, there were 13 patients who were less than 45 years old, and 39 patients were 45 years old or more at the time of cervical cancer diagnosis. The younger group had less median overall survival than the older group, with a statistically significant difference (21 months, 95% CI 19.93-22.06; 34 months, 95% CI 23.27-44.72, p = 0.021). However, they were comparable in the duration from cervical cancer diagnosis to bone metastasis diagnosis and the survival time after bone metastasis. Conclusion: Young patients with bone metastasis aged less than 45 years old at the time of cervical cancer diagnosis have a poorer prognosis than the elderly patients. Impact: To improve survival and quality of life, more intensive and novel multimodal treatments at the time of cervical cancer diagnosis should be considered in patients less than forty-five years, who can tolerate the side effects better.

The present study was carried out to evaluate the correlation of metastasis and prognostic factors in squamous cell carcinoma of head and neck. Examination was performed on a series of thirty-seven patients who were confirmed to squamous cell carcinoma and its lymphatic metastasis by pathologist. Correlations of metastasis and other factors such as angiogenesis, histologic grading, and p53 expression and ras oncogene were studied. The depth of tumors was around 1 to 27mm. Twenty cases were more than 10mm deep, of which seventeen cases were shown lymphatic metastasis. Total score of histologic grading including keratinization, nuclear atypia, growth pattern and intensity of inflammation was ranged from 5 to 10 points. Of these factors, nuclear atypia with intensity of inflammation, and nuclear atypia with growth pattern was correlated with nuclear atypia each. For angiogenesis, number of new-formed vessels were counted 13 to 58 each. Twenty-eight cases were shown to lymphatic metastasis. No correlation with histologic grading and lymphatic metastasis was found. The results of immunohistochemical staining for p53 and ras oncogene revealed that positive cases were 16 and 22, negative for 21 and 15 each. However, both were not correlated with histologic grading and lymphatic metastasis. These results were revealed that angiogenesis was not correlated with lymphatic metastasis of squamous cell carcinoma arising in head and neck. Nuclear atypia with intensity of inflammation and dysplasia with growth pattern were correlated with histologic grading, which suggested that more careful and adequate advice is needed for effective treatment.

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.

Background: An accurate assessment of potential lymph node metastasis is important for the appropriate treatment of early gastric cancers. Therefore, this study analyzed predictive factors associated with lymph node metastasis and identified differences between mucosal and submucosal gastric cancers. Materials and Methods: A total of 518 early gastric cancer patients who underwent radical gastrectomy were reviewed in this study. Clinicopathological features were analyzed to identify predictive factors for lymph node metastasis. Results: The rate of lymph node metastasis in early gastric cancer was 15.3% overall, 3.3% for mucosal cancer, and 23.5% for submucosal cancer. Using univariate analysis, risk factors for lymph node metastasis were identified as tumor location, tumor size, depth of tumor invasion, histological type and lymphovascular invasion. Multivariate analysis revealed that tumor size >2 cm, submucosal invasion, undifferentiated tumors and lymphovascular invasion were independent risk factors for lymph node metastasis. When the carcinomas were confined to the mucosal layer, tumor size showed a significant correlation with lymph node metastasis. On the other hand, histological type and lymphovascular invasion were associated with lymph node metastasis in submucosal carcinomas. Conclusions: Tumor size >2 cm, submucosal tumor, undifferentiated tumor and lymphovascular invasion are predictive factors for lymph node metastasis in early gastric cancer. Risk factors are quite different depending on depth of tumor invasion. Endoscopic treatment might be possible in highly selective cases.

Skin metastasis from papillary thyroid carcinoma is extremely rare. Due to similar histopathologic features, it is difficult to differentiate skin metastatic papillary thyroid carcinoma and some primary skin neoplasms without a clinical history. However, most of metastatic skin lesions showed a strong reactivity to the antithyroglobulin antibodies unlike primary skin neoplasms. Metastatic skin lesions must be completely removed and radiotherapy can be added. Investigators reported that prognosis of skin metastases from thyroid carcinoma is dismal and the average survival after it's diagnosis was only 19 months because distant metastases were often discovered at diagnosis of skin metastasis or during follow-up period. We report a case of skin metastasis from tall cell variant of papillary thyroid carcinoma. In our case, the anti thyroglobulin antibodies measured from cystic fluid from a skin lesion was more than 2000 IU/ml. Skin metastasis was diagnosed at 20 months after primary surgery for thyroid cancer and brain metastasis at 12 months after diagnosis of skin metastasis. Although skin metastasis is an ominous prognostic indicator in patients with thyroid carcinoma, a radical treatment for skin lesions and early diagnosis of distant metastasis could provide a chance to the patients to improve their survival.

Background: Supraglottic and hypopharyngeal regions drain into the upper deep cervical lymph nodes. And bilateral neck node metastasis is frequently occured especially, in the early stage. It influences on the prognosis of above diseases. The prognosis for patients wih supraglottic and hypopharyngeal cancers, although usually poor, has improved by modern imaging technique, better application of treatment modalities, increasing assortment of reconstructive procedures and improved application of radiation therapy. Objectives: This study was designed to obtain objective data about the patterns of neck node metastasis and to identify the necessity of elective bilateral neck dissection. Material and Methods: Twenty four patients with supraglottic cancer and twenty six patients with hypopharyngeal cancer were investigated from the chart review. Results: In supraglottic cancer, the most frequent sites of neck metastasis is level II (52.9%) and level III (52.9%) in ipsilateral side, level II (29.4%) in contralateral side, in hypopharyngeal cancer, level II (73.7%) and III (52.6%) in ipsilateral side, level II (10.5%) in contralateral side. In elective neck dissection, the occult metastasis is about 50% in supraglottic cancer, but there is no occult metastasis in hypopharyngeal cancer. Conclusion: In supraglottic cancer, elective bilateral neck dissection is necessary because of early contralateral neck metastasis, but in hypopharyngeal cancer, elective contralateral neck dissection may not be always necessary because of rare occult metastasis and contralateral neck metastasis.
