  • Purpose: The most important prognostic factors in gastric cancer are depth of invasion and lymph node metastasis. Therefore, the prognosis for serosa and lymph node negative gastric cancer is favorable. However, there is no general agreement on the prognostic factors in this subset of patients. This study was undertaken to evaluate the prognostic significances of venous invasion (VI), lymphatic invasion (LI), and perineural invasion (NI) in T1 and T2 gastric cancer without lymph node involvement. Materials and Methods: We retrospectively evaluated 206 patients with T1 and T2, lymph node negative gastric cancer who underwent a curative resection from 1989 to 1993 at Kangnam St. Mary's Hospital, Seoul, Korea. The Chi-square test was used to determine the statistical significance of differences, and the Kaplan-Meier method was used to calculate survival rates. Significant differences in the survival rates were assessed using the log-rank test, and the Cox regression method was used to evaluate independent prognostic significance. Results: The rate of VI, LI and NI correlated well with the depth of tumor invasion. The rates of VI (+) for T1 vs T2 was $0\%\;vs\;5.1\%$, of LI (+) was $5.6\%\;vs\;26.8\%$, and of NI (+) was $1.6\%\;vs\;26.8\%$ in NI (+). There were 13 recurrent cases, 10 cases out of the 13 were T2 gastric cancers, and the recurrence rate was higher in LI (+) and NI (+) cases than in LI (-) and NI (-) cases. The 5-year survival rates were $93.4\%$ in LI (-) cases, $77.4\%$ in LI (+) cases, $92.5\%$ in NI (-) cases, $74\%$ in NI(+) cases, $95.9\%$ in LI (-) NI (-) cases, and $73.9\%$ in LI (+) NI (+) cases. Multivariate analysis demonstrated that simultaneous LI and NI was the only significant factor influencing the prognosis. Conclusion: These results suggest that simultaneous lymphatic and perineural invasion may be an independent prognostic factor in patients with T1 and T2 gastric cancer without lymph node metastasis.

  • Purpose: E-cadherin and CD44H have been shown to play a role in the progression and the metastasis of tumors. This study evaluated the clinical correlations between expression of E-cadherin and CD44H and various clinicopathologic factors and the value of expressions of E-cadherin and CD44H as prognostic factors in Borrmann type IV gastric cancer. Materials and Methods: In 122 patients with Borrmann type IV gastric cancer, we performed the immunohistochemical stainings for E-cadherin and CD44H. We analyzed the correlation between the expressions of E-cadherin and CD44H and lymphatic invasion, venous invasion, perineural invasion, histologic type, lymph node metastasis, depth of invasion, stage, and peritoneal dissemination, and survival. Results: There were no correlations between reduced expression of E-cadherin and CD44H and lymphatic invasion, venous invasion, perineural invasion, histologic type, lymph node metastasis, depth of invasion, and stage. However, there was a significant correlation between lymph node metastasis and the lymphatic invasion (P=0.022). There was also a significant correlation between the peritoneal dissemination and CD44H expression (P=0.005). The 5-year survival rate was correlated with CD44H expression expression (P=0.026), peritoneal dissemination (P<0.01), depth of invasion (P<0.01), lymph node metastasis (P<0.01), stage of tumor (P<0.01), and lymphatic invasion (P<0.01). There was no correlation between expression of E-cadherin and survival rate. Conclusion: The expression of CD44H and peritoneal dissemination was correlated. The expression of CD44H was an independent prognostic factor in Borrmann type IV gastric cancer. Further prospective studies with a large number of cases are required.

  • Due to the fact that it reliably results in positive outcomes, lymph node flap transfer is becoming an increasingly popular surgical procedure for the prevention and treatment of lymphedema. This technique has been shown to stimulate lymphoangiogenesis and restore lymphatic function, as well as decreasing infection rates, minimizing pain, and preventing the recurrence of lymphedema. In this article, we investigate possible additional benefits of lymph node flap transfer, primarily the possibility that sentinel lymph nodes may be used to detect micrometastasis or in-transit metastasis and may function as an additional lymphatic station after the excision of advanced skin cancer.

  • Salivary duct carcinoma(SDC) is a highly malignant tumor of the salivary gland. The tumor is clinically characterized by a rapid onset and progression, the neoplasm is often associated with pain and facial paralysis. The nodal recurrence rate is high, and distant metastasis is common. SDC resembles high-grade breast ductal carcinoma. Curative surgical resection and postoperative radiation were the mainstay of the treatment. If facial paralysis is present, a radical parotidectomy is mandatory. Regardless of the primary location of SDC, ipsilateral functional neck dissection is indicated, because regional lymphatic spread has to be expected in the majority of patients already at time of diagnosis. If there is minor gland involvement, a bilateral neck dissection should be performed, because lymphatic drainage may occur to the contralateral side. The survival of SDC patient is poor, with most dying within three years. We experienced a unique case of SDC in parotid deep lobe. We report the clinicopathologic features of this tumor with a review of literature.

  • We evaluated the activity of methanolic extracts of Melaleuca cajuputi flowers against the filarial worm Brugia pahangi and its bacterial endosymbiont Wolbachia. Anti-Wolbachia activity was measured in worms and in Aedes albopictus Aa23 cells by PCR, electron microscopy, and other biological assays. In particular, microfilarial release, worm motility, and viability were determined. M. cajuputi flower extracts were found to significantly reduce Wolbachia endosymbionts in Aa23 cells, Wolbachia surface protein, and microfilarial release, as well as the viability and motility of adult worms. Anti-Wolbachia activity was further confirmed by observation of degraded and phagocytized Wolbachia in worms treated with the flower extracts. The data provided in vitro and in vivo evidence that M. cajuputi flower extracts inhibit Wolbachia, an activity that may be exploited as an alternative strategy to treat human lymphatic filariasis.

  • Hemolymph nodes of the Korean native cattle were observed gross anatomically and light microscopically in this study. Hemolymph nodes of the Korean native cattle were found mainly at the periphery of the thoracic and abdominal aortae although there were some other parts to observe these small organs. These organs were small in size and spherical or ovoid in shape, and color of them was dark red or gray in common with red band. The hemolymph nodes were surrounded by a relatively thick connective tissue capsules composed of dense collagen fibers with many scattered smooth muscle fibers and there was a hilus in each node. The parenchyma was divided into an outer cortex and an inner medulla. A few primary and secondary lymph nodules were observed in the cortex and there were diffuse lymphatic tissues among them. The medullary cords consisted of diffuse lymphatic tissues were separated by the medullary sinuses which filled with erythrocytes. The afferent and efferent lymph vessels were observed at the periphery of the capsule and the hilus area, respectively. The stroma of the hemolymph nodes was composed of reticular cells and fibers, and the meshwork of the stroma was filled with many lymphocytes and erythrocytes, and a few macrophages and megakaryocytes etc. These findings suggest that the hemolymph node of the Korean native cattle is involved in blood filtration and immune reaction.
