  • Currently the most important prognostic factor in lung cancer is the stage. In the current lung TNM classification system, N category is defined exclusively by anatomic nodal location though, in other type of tumours, number of lymph nodes is confirmed to be a fundamental prognostic factor. Therefore we evaluated the number of mediastinal lymph nodes as a prognostic factor in locally advanced NSCLC after multimodality treatment, observing a significant effect of the number of lymph nodes in terms of OS (p<0.01) and DFS (p<0.001): patients with a low number of positive mediastinal nodes have a better prognosis.

  • Prospective study of lymph node imaging of twenty stomach cancer cases with dissected lymph nodes being injected into the submucosa layer of stomach under surgical field was done. Total dose of 5 mci in 5 cc of volume was injected along the multiple sites of the lesser and greater curvature of stomach and collected lymph nodes within 2 hour of surgical time were placed under gamma camera and lymph node imagings were obtained. Pathological invasion of tumor and correlation of cold defect or hot uptake was compared each other. Tumor invasion of nodes revealed cold defect area which was correlated well with the pathological specimen. Correlation rate was 84.6%. We are planning to extend these procedures and trying endoscopic injection of positive imgaing agents such as Ga-73-3 Ig 2 alpha in future.

  • Objectives : The purpose of this case is to report the improvement of a patient with lymphedema due to axillary lymph node dissection after acupuncture therapy and herbal medicine. Methods : We treated the patient with Dong-Qi acupuncture, herbal medication(木通大安湯), lymph absorption massage, compresses, abdominal breathing. We measured the circumference of the patient's elbow and wrist every day at 6pm. Results : Since being hospitalized, the circumference of the patient' elbow and wrist has been decreased and VAS score has gotten lower gradually. Conclusions : We considered Dong-Qi acupuncture, herbal medication had a useful effect on lymphedema due to axillary lymph node dissection with lymph absorption massage, compresses, abdominal breathing.

  • Mediastinal lymph node dissection is a method that increases the long term survival of patients with an esophageal carcinoma. However, dissection of the left mediastinal lymph node is almost impossible, as it is not easy to see. Herein, a left mediastinal lymph node dissection, with thoracoscopy through a cervical incision wound during minimal invasive esophageal surgery, is reported.

  • The life cycle of Theileria sergenti(T sergenti) in cattle, especially Korean native cattle, was not proved clearly. To find schizont stage in the life cycle of T sergenti in Korean cattle, T sergenti schizonts in the cells of parotid lymph nodes from 10 adult Korean cattle were examined. Lymphoid cells which were separated from these lymph nodes were cytocentrifuged to observe the parasites in the cells. T sergenti schizonts were detected in the cells of lymph nodes of 6 cattle out of them by IFA(Indirect Fluorescent Antibody) test and Giemsa stain. By peroxidase stain, the cells which contain schizonts were proved lymphoid cells. T sergenti schizonts identified by IFA test were able to be restained by Giemsa stain. Also, merozoites were observed in peripheral blood of the same 6 cattle that had schizonts, by giemsa stain, but not observed in the 4 cattle that had not been detected schizonts. As a part of life cycle of T sergenti, schizonts were observed in the lymphoid cells of Korean cattle.

  • Purpose: In the UICC staging system, stage IV contains not only those patients with distant metastasis but also patients with far advanced T and N status but without distant metastasis. We investigated the prognostic factors of stage IV gastric carcinoma patients without distant metastasis after curative resection. Materials and Methods: 190 stage IV gastric carcinoma patients without distant metastasis were reviewed after curative resection. Results: Male sex, distal third location, Borrmann type III, IV and histologically undifferentiated type were common. 5 year survival rate of the 190 patients was $22.2\%$. Depth of invasion and lymph node metastasis did not influence survival. The lymph node ratio (positive lymph node / retrieved lymph node) and combined resection affected survival by univariate and multivariate analysis. Conclusion: Combined resection and positive lymph node ratio were the independent prognostic factors in the patients with stage IV gastric carcinoma who underwent curative resection.

  • Metastatic squamous cell carcinoma from a cancer of unknown primary (CUP) affecting the intrathoracic lymph node is very rare. We reported a case of metastatic squamous cell carcinoma in the hilar and interlobar lymph node from a patient with CUP and reviewed the associated literature. Abnormal mass in the right hilar area was incidentally detected. A chest computed tomography scan showed a 2.5-cm diameter mass in the right hilum that had changed little in size for 3 years. The patient underwent a right pneumonectomy and mediastinal lymph node dissection. A metastatic squamous cell carcinoma in the hilar and interlobar lymph nodes without a primary lung or other lesion was diagnosed. The patient received adjuvant chemotherapy for a diagnosis of T0N1M0 lung cancer.

  • Early gastric cancer (EGC) is defined as tumor invasion confined to the mucosa or submucosa, regardless of the presence of regional lymph node metastasis. Lymph node metastasis is the most powerful and important prognostic factor for gastric cancer. Based on the risk of lymph node metastasis in EGC obtained from a large number of surgical cases in Japan, it was suggested that the criteria for endoscopic mucosal resection (EMR) and endoscopic submucosal resection (ESD) as local treatment for EGC might be extended. However, extending the indications for EMR and ESD remains controversial because the long-term outcomes of these procedures have not been fully documented, and there is a risk for lymph node metastasis. Furthermore, current diagnostic imaging techniques are unsatisfactory for accurately predicting metastasis to lymph nodes. Moreover, the long-term results of standard radical gastrectomy including minimally invasive procedures for stage IA have been increasing and have reached 99 to 100%. To determine the true efficacy of endoscopic resection of EGC, we need more evidence of long-term follow-up, standardization of techniques, and pathological interpretation.

  • Background and Objectives: Sirtuins (SIRTs) play important roles in cellular and organismal homeostasis. They have distinct gene expression patterns in various cancers; however, the relationship between SIRT expression and the progression of thyroid cancer is unclear. We investigated the expression of SIRTs in patients with papillary thyroid carcinoma (PTC) and their role as biomarkers for predicting the aggressiveness of this disease. Materials and Methods: We used immunohistochemical staining to evaluate the expression of SIRT1 and SIRT3 in tumor specimens from 270 patients with PTC. We also evaluated the potential association between SIRT expression and diverse clinicopathological features. Results: High SIRT1 expression was negatively correlated with lymphovascular invasion, central lymph node metastasis, and lateral lymph node metastasis. Multivariate analyses revealed that high SIRT1 expression was a negative independent risk factor for lateral lymph node metastasis. By contrast, high SIRT3 expression was positively correlated with locoregional recurrence. Interestingly, when patients were grouped by tumor SIRT expression patterns, the group with low SIRT1 expression and high SIRT3 expression was correlated with more aggressive cancer phenotypes including central lymph node metastasis and lateral lymph node metastasis. Conclusion: Our results suggest that SIRTs play dual roles in tumor progression, and the combination of decreased SIRT1 expression and increased SIRT3 expression is significantly associated with a poor prognosis in patients with PTC.

  • Contralateral axillary lymph node metastasis is a rare entity in breast cancer and is currently classified as a distant metastasis; however, recent studies have proposed aggressive curative treatment since this entity may manifest as a locoregional disease. Herein, we report a rare case of contralateral axillary lymph node metastasis that presented with imaging findings 22 months after the initial breast cancer diagnosis in a 67-year-old female. The patient underwent lymph node dissection of the axilla with adjuvant chemotherapy and radiotherapy. A follow-up examination 6 months after surgery showed no evidence of tumor recurrence or metastasis.
