Recurrence rate of stage 1a3 lung adenocarcinoma after surgery

Lung adenocarcinoma stage IA3 refers to stage I, which is an early phase of cancer. The postoperative recurrence rate for lung adenocarcinoma at stage IA3 is not very high, as earlier stages generally correlate with lower recurrence rates after treatment.

For patients with stage IA3 lung adenocarcinoma, timely surgical resection is recommended to help control disease progression. At this stage, tumor metastasis typically has not occurred, and distant lymphatic systems and other organs have not yet been invaded by cancer cells. Because the malignant tumor is relatively small, it usually does not cause significant compression on surrounding tissues, so patients with stage IA3 lung adenocarcinoma often do not exhibit obvious symptoms. After surgical resection, the prognosis is generally favorable, with a high 5-year survival rate and low recurrence rate. Patients with carcinoma in situ can achieve cure after surgery, while minimally invasive adenocarcinoma carries a very low risk of tumor metastasis, with rare postoperative recurrence—approximately 1% 5-year recurrence rate. In contrast, about 10%–20% of patients with invasive adenocarcinoma experience recurrence or metastasis within 5 years after surgery.

After surgical treatment, patients with lung adenocarcinoma should quit smoking and limit alcohol consumption, eat more fresh vegetables and fruits, avoid excessive intake of processed, smoked, or grilled foods, and regularly engage in low-intensity aerobic exercise. They should also follow medical advice for regular follow-up visits and promptly seek medical attention if any discomfort arises.
