The objective of the study was to evaluate the computed tomographic (CT) features and growth rates of pulmonary metastases from colorectal cancer (CRC) on serial CT scans. The study included 17 patients (28 pulmonary metastases) who underwent metastasectomy from CRC. The characteristic CT features include well-defined round or oval nodules in the peripheral or subpleural/fissural lung with frequent feeding vessel sign. The mean tumor volume doubling time was calculated as 160 days. With these growth rates, short-term follow-up (i.e., 5-6 months) would be helpful.
本研究旨在评估结直肠癌（CRC）肺转移瘤的 CT 特征和生长速度。本研究纳入了 17 例行结直肠癌转移瘤切除术的患者（28 个肺部转移瘤）。特征性 CT 表现包括外周或胸膜下/裂层的边界清楚的圆形或卵圆形结节，常伴有滋养血管征。平均肿瘤体积倍增时间为 160 天。根据这些生长速度，短期随访（即 5-6 个月）将有所帮助。
