In general, the European pathological examination method primarily relies on pathologists and does not require the involvement of surgeons. The Japanese pathological evaluation approach, on the other hand, involves the intervention of surgeons, particularly in the extraction of lymph nodes from fresh specimens and the assessment of specimen quality. Given that the Japanese pathological assessment method lacks systematic evaluation and there is currently no literature clearly demonstrating its diagnostic accuracy, the main objective of this study is to verify whether the diagnostic accuracy of the Japanese pathological investigation method is inferior to that of the European pathological evaluation method.
