To evaluate significant postoperative prognostic factors for esophageal carcinoma, clinicopathological findings and several markers for biological malignant potential were studied, including cell nuclear DNA contents, EGF receptor, p53 protein, MMP-2, Ki-67 positive cell rate, and tumors infiltrating Leu 7 cells. The subjects of this study were 96 patients with thoracic esophageal carcinoma, who underwent radical surgery with extended lymphadenectomy. In the pathological findings, the postoperative survival rate significantly correlated with depth of invasion (pT1(-2) vs. pT3, p = 0.003), lymph node involvement (pNo vs. pN1, p = 0.0002), vascular invasion (-vs. +, p = 0.0003), stage (pSt. 1-2A vs. 3, p = 0.0018), and the number of node involvements (1-3 vs. more than 4, p = 0.025). Analyzing the markers for the malignancy, a significant difference in postoperative mortality due to the relapse was recognized with p value of 0.0009 between Ki-67 positive (under 1%) and Ki-67 negative (over 1%) tumor. Ki-67 positive tumor significantly correlated with the mortality in both cases with pNo (p = 0.024) and pN1 (p = 0.020). Low-grade tumor infiltrating Leu 7 cells significantly correlated with the mortality (Grade 1+ vs. 2+, p = 0.013; Grade 1+ vs. 3+, p = 0.008). These results suggest that Ki-67 study is a useful prognostic factor after radical surgery for thoracic esophageal carcinoma.

The interaction and/or balance between matrix metallopeptidase (MMP)-2 and tissue inhibitor of metalloproteinase (TIMP)-2 in vivo may play important roles in the process of tumor growth, invasion and metastasis of malignant melanoma. In this study, we investigated the serum levels and immunohistochemical expression of MMP-2, TIMP-1 and TIMP-2 in patients with melanoma and analyzed the correlation with clinicopathological parameters. The level of serum MMP-2 in patients was significantly higher than that of the control. Moreover, the level of MMP-2 was significantly higher than that of the control in patients who were: (i) female; (ii) pT1 and pT4; (iii) with and without lymph node (LN) metastasis; (iv) in stage I and stage IV; (v) with and without recurrence; and (v) alive and dead. The level of serum TIMP-1 in patients with melanoma was significantly higher than that of the control. Among melanoma patients, the level of TIMP-1 with pT4 was significantly higher for patients who were: (i) pT1 and pT3; (ii) with LN metastasis (vs those without); (iii) in stage IV (vs those in stages I, II and III); and (iv) dead (vs those alive). The level of serum TIMP-2 in patients with melanoma was not different from the control. However, the level of TIMP-2 in patients with pT4 was significantly higher than for patients who were: (i) pT1, pT3 and control; (ii) with LN metastasis (vs those without metastasis and control); (iii) with stage IV (vs those in stages I and II and control); (iv) in recurrence (vs control); and (v) dead (vs those alive and control). These results suggest that increased serum levels of TIMP-1 and TIMP-2 reflected the extent of metastatic melanoma lesions, and that serum levels of TIMP-1 may be a new useful marker for melanoma progression.
