Subject	Oncology
Specific subject area	Postoperative prognosis of early-stage lung adenocarcinoma with histological information
Type of data	Table, Fig.s
How data were acquired	The data were acquired from a survey of medical records and microscopic findings of surgically resected specimens at National Cancer Center Hospital, Tokyo, Japan.
Data format	Raw and partially filtered
Parameters for data collection	The data consist of pathological findings of stage IA lung adenocarcinoma and adenocarcinoma in situ, including total tumor diameter, size of invasion, lymphovascular invasion, and histological subtype. The data also show clinical information including age, gender, operative procedure, tumor location, and prognosis.
Description of data collection	The data were acquired from 1,032 cases of pathological stage IA lung adenocarcinoma and adenocarcinoma in situ who underwent complete resection between 2007 and 2012 at National Cancer Center Hospital, Tokyo, Japan. A pathological review was performed to assess total tumor size, size of invasion, histological subtype, lymphovascular invasion, and presence of cancer-associated active fibroblast (CAF). Age, gender, tumor recurrence and overall survival status were collected from medical records.
Data source location	5-1-1, Tsukiji, Chuo-ku, Tokyo, Japan
Data accessibility	The data are presented with the article.
