There have been some controversies on prognostic significance of lymph node (LN) micrometastasis (MM) in advanced gastric carcinomas (AGCs). The present study aimed at 1) determination of prognostic significance of MM, 2) evaluation of the relationship between MM and clinicopathological parameters, and 3) determination of LN group where MMs were frequently found. We studied 70 cases of AGC without LN metastasis on initial examination. The tumors were examined for location, size, depth of invasion, differentiation, histologic type, lymphatic invasion, and c-erbB-2 expression. To evaluate MM, pancytokeratin immunohistochemistry was performed in all LNs from 70 cases of AGCs. Among 2,203 dissected LNs from 70 patients, 37 (1.6%) LNs from 19 (27.1%) patients revealed MM. Micrometastases were seen in only group 1 and 2 LNs: none had group 3 and 4 LN involvement. The gender, age, tumor size, location of tumor, histologic type, differentiation, depth of invasion, lymphatic invasion, and c-erbB-2 expression were not significantly associated with MM status. The survival time of the MM-positive group (mean: 62 months) was significantly shorter than that of the MM-negative group (mean: 72 months) (p=0.046). The findings of this study indicate that the presence of MM in LNs is an important prognostic factor in AGC patients.

Compliance of epileptic patients is one of the most important factors for adequate therapy. Recently, it had been shown that the variability of three serial measurement of the serum levels of antiepileptic drug(AED) may be used as an indication of the degree of compliance. Coefficient variation(CV) of serum drug levels calculated by only one AED had been used to determine the compliance in epileptic patients who took multiple AEDs. We attempted to evaluate the CV of AEDs and then find the objective clue of compliance and the compatible therapeutic planing according to CV. Ninety seven epileptic patients of outpatients department of the Gyengsang National University Hospital were entered to this study. All patients were taking medication at least for 6 months without any changes of drug regimen. Patient's information was acquired by reviewing the chart and interview with questionnaire. With these informations, we determined the compliance of the patients. Antiepileptic serum levels were measured three times at intervals of at least two to four weeks apart, and their CV was calculated. We compared the CV between the compliant and non-compliant group in each AED(phenytoin, carbamazepine , valproic acid) and three drugs in the compliant group. The mean CVs of phenytoin, carbamazepine and valproic acid in the compliant group were 18.3+/-13.0, 15.2+/-10.2 and 23.8+/-8.9, respectively(mean+/-SD). The mean of CV in the compliant and the non-compliant group were 17.9+/-10.9 and 38.8+/-27.2, respectively. The CVs of the compliant group were significantly lower than those of the non-compliant group(p<0.05). However, CVs had no significant difference between three antiepileptic drugs. This study showed that CVs of AEDs were not different between each AEDs, even though they possess different pharmacokinetic properties. Therefore, the CV of one AED can be used in determining the compliance of the epileptics who are taking multiple AEDs.
