If the lateral margin is close (=<0.2cm) or is involved in the tumor, the corresponding directions should be written together.

In our institution, lateral margin involvement is evaluated and reported in 4 directions. In about 14 hundred early gastric cancers treated by ESD, lateral margin involvement was documented in 5.5%. Among them, 60% were single lateral margin positive. 40% were multiple lateral margin positive.

Histologic heterogeneity was seen in 25% and 46%, respectively. Extremely well differentiated adenocarcinoma was 7% and 25% in the two groups. This difference was statistically significant. Cases of technical difficulty was the same in the two groups. Surprisingly, the procedure time was shorter in the multiple lateral margin positive group. We thought that the technical aspect was not related to the number of positive lateral margin.

In this figure, yellow bar is the proportion of the cases with HH or EWDA. It showed that the ratio of HH or EWDA is increasing according to the number of lateral margin positive direction. And the difference was statistically significant.

During the past 8 years, we performed 1,400 ESDs for early gastric cancers. The overall rate of positive lateral resection margin was 5 percent. Early additional ESD was done in 16 cases. Curative resection by early additional ESD was possible in all cases except one case. In the additional ESD pathology, residual cancers were found in 10 cases. There was no residual tumor in 3 cases. We thought that early additional ESD is quite useful in selected cases with positive resection margin.


3. [SMC experience] Ablation treatment for positive lateral margin (EndoTODAY 20121220)

In cases with lateral margin involvement after ESD, early additional ablation treatment is another important treatment option. In this case, posterior resection margin was positive of malignancy.

Although no residual tumor was suspected in the repeat endoscopy, ablation treatment using argon plasma coagulation (APC) was done. There was no recurrence in the follow-up endoscopies for more than 4 years.


A few weeks ago, I received a question about the safety of ablation treatment of positive resection margin. The point was that we don¡¯t know the depth of invasion of the possible residual tumor near the positive resection margin. Let¡¯s suppose this is the tumor.

Endoscopic resection will be done like this, and one resection margin was positive. Yes, I agree. We don¡¯t have the information about the depth of invasion of the possible residual tumor. However, we already have information of depth of invasion from most of the tumor. Usually the invasion is deepest in the middle of the tumor.

In this regard, ablation treatment (green area in the picture below) can be done quite safely.

Eighty-two patients (84 lesions) with LRM+ after EMR (n = 45) or ESD (n = 39) were enrolled. Forty patients underwent additional gastrectomy or ESD, and 44 were closely observed. The residual/recurrent tumor rate was 34.5 % (29 of 84 lesions). Univariate analysis found that the residual/recurrent tumor was associated with the endoscopic resection type (EMR), undifferentiated histology, number of involved directions, rate of lateral resection margin involvement and the total length (mm) of the lateral resection margin involved by the tumor. In multivariate logistic regression analysis, undifferentiated histology and rate (%) were independent risk factors.

The rate of pathological non-curative resection of EGC by ESD is about 10-20%. In additional surgery for non-curative resection cases, local residual tumor is found in 5-10%, and lymph node metastasis is also found in 5-10%. In this case of histological heterogeneity, lateral margin was involved. Surgery was done and 1.2cm x 0.3cm sized residual tumor in lamina propria was found. (EndoTODAY À§¾Ï 650)
