- Mixed adenocarcinoma: a mixture of differentiation type and undifferentiated type histology
(1) Mixed adenocarcinoma comprised od 10.7-44.4% of EGCs and correlated with tumor size, depth of invasion, and lymph node metastasis
(2) In particular, undifferentiated predominant mixed type is a significant risk factor for lymph node metastasis.
(3) Mixed adenocarcinoma is one of major tumor factors contributing histologic discrepancy between endoscopic biopsy and resection specimen.

There are two important biases in the cancer screening. The first one is very famous, the lead time bias. I think all individuals in this hall already understand this type of bias. Even if we may detect cancers earlier, the overall survival gain is another issue due to the lead time bias.


The second bias is the length-time bias. It means cancers detected in the screening program may be less aggressive. This bias is especially important for the elderly population. If some cancers in the elderly people are very slow-growing, is there any reason that we need to find them?


Survival gain by the cancer screening is usually like this. At some age, the survival gain can be zero. After that point, screening can actually decrease the individual¡¯s survival. We need to stop before that age. But, the problem here is that we don¡¯t know exactly when to stop.


In terms of screening for cancers, we need to consider the life expectancy. Screening tests are usually recommended when the expected survival is longer than 10 years. In this regard, screening at the age of 80 is usually not recommended.


Do you know the Hoerr¡¯s law? It means it is difficult to make the asymptomatic patient feel better. Regarding the screening in the elderly population, we need to ask to ourselves. We are really making the elderly people feel better, be happier by all the screening and aggressive treatment?


A few years ago, US preventive services task force recommended against routine colonoscopy for adults with ages 76 to 85.


This is one of many evidences supporting the US preventive services task force recommendations. After 75 years, screening colonoscopy showed no more benefit. Actually, screening colonoscopy after 75 years makes more and more complications. 75 is a good age for stopping screening colonoscopy.


As a box summary, I can say that more is not always better, especially in the cancer screening in the elderly. Sometimes, less may be better. We need to stop at some point.

In the surgery group, 11 have lymph node metastasis, which means 5.7%. Patients with lymph node metastasis were older. To our surprise, the rate of lymph node metastasis was not different by the tumor size, depth of invasion, histological differentiation, and lymphovascular invasion in the endoscopically resected specimen. So, basically we found no predictor of lymph node metastasis in this analysis.

Rate of progression into the advanced cancers were different between 2 groups. Five advanced cancers were found in the observation group, and only one metastatic disease was found in the surgery group. This difference - 6.3% versus 0.5% - was statistically significant.

This is the summary of six cases with documented progression of gastric cancer. As you can see, all cases have submucosal invasion of more than 200 micrometer and all have evidence of endolymphatic invasion.
