■ Features

【Compare JP rules and UICC】 Switch tabs to see how the stage differs between the Japanese classification and UICC/AJCC for the same case. Esophageal cancer is organized by histology (squamous cell carcinoma / adenocarcinoma) and separated into clinical and pathological staging.

【TNM notation included】 Results show the stage together with the T/N/M notation, ready to use in charts and case discussions.

【Color-coded by stage】 Results are color-coded so the extent of disease is clear at a glance.

【Inputs tailored to each cancer】 For hepatocellular carcinoma, the Japanese rules derive the stage from tumor number, tumor size and vascular invasion; the UICC pathological classification uses histology, grade and tumor location.

【Sources are cited】 Full bibliographic details of every classification manual are included, with DOI links to the societies' official English editions and links to their websites, so the basis for each stage can be checked on the spot.

【Japanese and English】 Tap the toggle at the top right to switch the entire interface, including factor descriptions and the reference list, between Japanese and English.

【Works offline】 Available whenever you need it, with no network connection and no account required.
