Stage-Ia lung cancer: More than 90% survival rate

Stage-Ia lung cancer: More than 90% survival rate


Stage-Ia lung cancer: More than 90% survival rate. Stage Ia lung cancer can be cured almost completely, with a survival rate of more than 90%, and the key is early detection.

Lung cancer is a topic of concern to many people. The pathological type of lung cancer is different now. Twenty or thirty years ago, lung adenocarcinoma is the majority, accounting for 50-60% of all lung cancers.

With the improvement of health awareness and the development of CT technology, the detection rate of early lung cancer has increased significantly.

Stage-Ia lung cancer: More than 90% survival rate



What does period Ia mean?

According to the standardized TNM staging of lung cancer, there is no lymph node metastasis or distant metastasis in stage I. Stage Ia refers to T1N0M0, and T1 means that the maximum diameter of the lung tumor is ≤3cm. According to the size of the primary tumor, T1 is divided into T1a, T1b and T1c.

T1a refers to the maximum diameter of the primary tumor ≤ 1 cm, confined to the lung and visceral pleura, and does not involve the main bronchus. T1b refers to the maximum diameter of the tumor> 1cm, ≤ 2cm; the maximum diameter of the T1c primary tumor> 2cm, ≤ 3cm. According to different T1 stages, Ia stage is divided into Ia1, Ia2, and Ia3.

According to the requirements of lung cancer treatment guidelines, thoracoscopic anatomical lobectomy + hilar mediastinal lymph node dissection is preferred for patients with stage Ia lung cancer, and stereotactic radiotherapy (SBRT/SABR) is performed for patients who are not suitable for surgery.

The recurrence rate of stage Ia lung adenocarcinoma is very low, and the cure rate is almost equal to that of carcinoma in situ. The 5-year survival rate and cure rate after radical surgery are close to 90%.

If all lung cancer patients can be found and treated surgically in stage Ia, the overall cure rate of lung cancer patients will be greatly improved.

Stage Ia patients do not need postoperative adjuvant treatment after surgery. It does not mean that stage Ia patients can sit back and relax after surgery. Regardless of them, regular review is also very necessary.

For patients with stage Ia3, poorly differentiated patients, near surgical margins, and incomplete lymph node dissection, there are certain high-risk factors for recurrence, and close observation is still needed.

The recurrence rate of stage Ia lung adenocarcinoma is very low. This is for the affected population. For individuals, it is not 100% sure that there will be no recurrence, or the probability of recurrence.

In fact, for patients, they always think about whether they will relapse and how high the recurrence rate is. This is a manifestation of mediocrity. The occurrence and development of lung cancer are related to genetic genes, the patient’s environment, bad living habits, and the patient’s mentality and emotions.

Therefore, do not worry about the recurrence rate all day long. Negative emotions are very detrimental to the recovery of the disease. Although it is unfortunate to have lung adenocarcinoma, it is a very lucky person to be found in stage Ia. As long as you face it positively, actively treat and review it, the result must be very good.

The earlier lung cancer is detected, the better the prognosis, so we advocate early physical examinations for high-risk groups and the elderly, and screening for lung cancer. Regardless of the type of tumor, the later the stage, the shorter the survival time and the more limited the treatment.
