Abstract:
BACKGROUND:It has been known that the volume doubling time (VDT) of different lung nodule types is different. At present, there is still a lack of studies about the volume doubling time of lung cancer with different pathological types. The purpose of the study is to explore the factors influencing the progression of the early-stage adenocarcinoma, and provide some reference for the follow-up strategy of lung nodules by retrospective analysis of the image data of 143 early-stage adenocarcinoma.
METHODS:143 cases of the early adenocarcinoma were classified according to the 2015 World Health Organization Classification of Lung Tumors and the Eighth edition of the tumor-node-metastasis (TNM) classification of lung cancer. The volume doubling time was calculated with reference to the revised Schwartz formula.
RESULTS:Among the 143 cases of the early adenocarcinoma, 50 cases (34.97%) were in progression. By multivarIate analysis, there were several factors associated with the progression of the early adenocarcinoma: the follow-up time, the dimension of nodule, the pathological type, the nodule type and the pathological stage. The VDT of lepidic predominant adenocarcinoma (LPA) is (594±272) d. The VDT of the invasive adenocarcinoma with lepidic part, but not predominant, is (520±285) d. The VDT of the invasive adenocarcinoma without lepidic part is (371±183) d.
CONCLUSIONS:About 35% of the early adenocarcinoma is in progress. Whether with the lepidic component is a positive factor to the speed of tumor progression.
