Growth rate of residual lung ground-glass nodules after lung cancer resection In clinical work, some patients have surgical resection of the main lesion, but there are still some residual nodules, which cannot be completely resected because the nodules are too small or too deep in location. The follow-up of these residual nodules has become a problem for many postoperative patients. I. Will the residual nodules grow? Due to a previous history of lung cancer, residual nodules have a higher risk of growth than normal nodules. A study by a Korean scholar showed that after resection of the main lesion and 3 years of follow-up, for postoperative residual nodules, 7.3% of patients showed nodule shrinkage, 52.4% of patients showed unchanged nodules, and 40.2% of patients showed nodule enlargement. NaturalProgressionofGround-glassNodulesafterCurativeResectionforNon-smallCellLungCancer Another Korean scholar, Kim et al. observed 92 patients with new or multiple GGNs after undergoing primary foci resection. Of the 139 nodules they included, 23 (16.5%) had increased nodal volume. This result was not significantly different from the GGN growth rates reported in previous studies without a history of lung cancer. II.PRIMARY PATTERN OF RESIDUAL NODULES GROWTH The primary pattern of residual nodal growth is the enlargement of the nodule itself, and less frequently, the appearance of new nodules. Third, the main factors affecting the growth of residual nodules: 1. the initial diameter of the residual nodule, greater than 8 mm, or greater than 10 mm residual nodule, the risk of growth is higher 2. continued smoking after surgery 3. the presence of a solid component in the residual nodule after surgery for lung cancer, the residual nodule is likely to appear slow enlargement, so the first operation, as far as possible, to remove the nodule that is likely to increase, and also regular review follow-up after surgery Therefore, the first surgery should be performed to remove the nodules that may be enlarged as much as possible, and regular follow-up should be performed after surgery.
