How long can the patient with lung cancer live?


How long can the patient with lung cancer live? Some people can live for 5 years without treatment, and pay attention on  4 factors.

Regardless of whether the consequences of any disease are good or bad, there are individual differences, and the data of one patient cannot be representative of all disease patient groups.
Lung cancer, as one of the main causes of death from cancer in the world, has ranked first in the incidence and mortality of all cancers in many countries, and has become the number one cancer that threatens human health and life.

How long can the patient with lung cancer live?

As people’s understanding of tumors continues to deepen, more and more cancers have been well diagnosed and treated, but at present, only lung cancer has not made a breakthrough.

Although the treatment methods for lung cancer are continuously improved, there is no method that can greatly improve the survival time of lung cancer. At the same time, the incidence of lung cancer is getting higher and higher due to the continuous aggravation of air pollution, which has replaced liver cancer as a new one. Cancer King”.

It is generally believed that early lung cancer can be treated with surgery to achieve better results, and the 5-year survival rate is correspondingly higher. Therefore, early diagnosis and early treatment of lung cancer are very important.

But in fact, many lung cancer patients  are already in the middle or advanced stage when they see a doctor. At this time, the treatment plan is not only complicated, and the survival time of lung cancer is generally only about one year.

Of course, there are some individual patients who survive for a long time. For example, we have encountered such a patient in the clinic. A male, 52 years old, was already at an advanced stage when he was diagnosed. Because it was an advanced stage, the patient decided to give up a series of Treat, go home “waiting for the arrival of death”.

After returning home, the patient continued to work and live as usual, so the patient who was told that there was only one year, but lived for 5 years, of course, eventually died because of cancer metastasis.

Although the patient missed the best time for surgery due to the late stage of lung cancer, the patient’s tumor grew slowly during this period, so the survival time could exceed 5 years even if he could not be treated by surgery.


What factors are related to the survival time of lung cancer?

1. Types of lung cancer

Lung cancer is divided into adenocarcinoma, squamous cell carcinoma, large cell carcinoma and small cell carcinoma. In terms of growth rate, the development of squamous cell carcinoma is relatively slow, the time of metastasis is also late, and there are more opportunities for surgical treatment;

The development of small cell lung cancer is relatively rapid, and the metastasis is also early;

Although adenocarcinoma does not develop as fast as small cell lung cancer, it grows faster than squamous cell carcinoma.

For adenocarcinoma, there are many treatment methods that can be selected. Therefore, the comprehensive use of various treatment methods for adenocarcinoma patients can greatly extend the survival time of adenocarcinoma patients.

2. The degree of differentiation of lung cancer

Cancer cells are produced by gene mutations in normal cells of the body, so the degree of cell changes is clinically called the degree of differentiation.

The better the differentiation of cancer cells, the closer their morphology to normal cells, but on the contrary, the higher the degree of malignancy; that is to say, the higher the degree of malignancy if the cancer cells are poorly differentiated.

When the cancer is highly malignant, it grows faster and metastasizes earlier.

3. The patient’s mentality determines the outcome of the disease

Patient mentality is an important factor affecting survival time. Once a person loses the confidence to live, he may deteriorate and lose his life in a short period of time.

If cancer patients do not have the confidence to persist, it will be difficult to persist in the treatment process because of the series of pain caused by the treatment.

As long as you can persist, you will see the dawn of life.

4. Treatment methods

There is a data analysis showing that 80% of patients with lung cancer are already at an advanced stage when they are diagnosed, which means that 80% of patients have lost the best time for surgical treatment and can only use chemotherapy, radiotherapy, targeted therapy and immunotherapy. And other treatment methods.

Therefore, the early treatment of lung cancer is mainly surgery, and the middle-term treatment of lung cancer can choose surgery, preoperative radiotherapy, postoperative radiotherapy, chemotherapy, and even targeted therapy, immunotherapy, etc.

Before targeted therapy, the average survival time of patients with advanced lung cancer was only 8 to 10 months, so it is very important for lung cancer to be able to do targeted therapy.

Targeted therapy is a drug treatment for tumor-specific gene mutations. Because these genes are tumor-specific, targeted therapy has less impact on normal cells, and the response during treatment is much smaller than chemotherapy. However, treatment The effect is better.

At present, among the four cell types of lung cancer, only adenocarcinoma has more opportunities to obtain targeted therapy. However, genetic testing is required before treatment. Only corresponding gene mutations can be treated with targeted drugs.


Generally, patients who can undergo targeted therapy have a long survival time, a low recurrence rate, and a corresponding improvement in the quality of life.

That is to say, tumor survival time and survival rate are both for a large group of patients, and they are also the conclusions found through statistics of many patients in the process of clinical trials. If you want to be specific to the survival time and survival rate of each patient, you can only As a reference, it cannot be used as a basis for medical statistics.

In fact, in simple terms, there are individual differences regardless of the outcome of any disease, and the data of one patient cannot be represented by all groups of patients with the disease.
