How long can Laryngeal Cancer live?
Laryngeal cancer has a relatively poor prognosis if detected at an advanced stage. So how long does laryngeal cancer live and depends on what factors?
Understand how to calculate 5-year survival rate
One of the questions that cancer patients often ask their doctors is "How long do I have to live?". To answer that question for the patient, the doctor will rely on statistics.
Statistics are numbers that describe the trend of an event when measured, counted, or calculated over a large number of patients (e.g. mortality, progression-free survival, duration of disease). disease-free survival = time from complete remission until the disease recurs…).
Cancer survival statistics are usually based on factors such as the type of cancer, the stage of the cancer, the age of the patient, the time period measured (such as survival time 1 year, 2 years, 3 years, 4 years). , 5 years…). Depending on the type of cancer, the stage of the cancer, appropriate survival limits will be set to measure and re-statistical to give the numbers describing the mortality trend of the disease as low or high, địa chỉ cắt bao quy đầu quận 1,long or short… (1)
Survival time is one of the factors of disease prognosis. Prognosis depends on the type of disease, the stage of the disease, the degree of response to treatment, the ability to recover after treatment .... The disease has a poor prognosis, which means that the patient's ability to recover is low, the mortality rate is high and vice versa. Survival rate is the percentage of patients who are alive after a certain period of time. Survival rates can measure any length of time, long or short (1 year or 5 years, 10 years...). However, researchers often use the 5-year mark to measure survival rates for people with cancer. The 5-year survival rate means the percentage of people who are alive 5 years from the time of cancer diagnosis. This rate does not include patients who died from causes other than cancer.
For example:
The 5-year survival rate of cervical cancer patients is 66%, meaning that for every 100 patients diagnosed with cervical cancer, after 5 years, 66 patients will still be alive. The 5-year survival rate of patients with early cervical cancer is 92%, which means that for every 100 patients with an early cervical cancer diagnosis, 92 patients are still alive after 5 years. (2) Doctors often use 5-year survival rates to evaluate and compare treatment options. They consider survival rates to be a good indicator of the following:
Whether the cancer is responding to treatment; Whether the treatment successfully prolongs the patient's life.
In the United States, a program called Surveillance, Epidemiology, and End Results (SEER) is one of the most reliable sources of information on cancer statistics. This program collects, processes, and provides cancer statistics to contribute to efforts to reduce the burden of disease on American citizens. SEER is sponsored by the National Cancer Institute (NCI).
How long does laryngeal cancer live? The survival prognosis of patients with laryngeal cancer is quite high if detected and treated at an early stage. The survival prognosis of laryngeal cancer depends mainly on the stage of the disease at the time of diagnosis (that is, on the extent of tumor invasion and spread, and on the status of the lymph nodes and distant metastases). In addition, it depends on factors such as:
Cancer cell type and histological grade of cancer cells. Histology describes the degree of abnormality of cells when viewed under the microscope, the more abnormal the cells, the higher the histology, and the worse the prognosis. Tumor location: Tumors in the glottis usually have a better prognosis than the epiglottis or the subglottis. địa chỉ cắt bao quy đầu quận 3. Health and condition of the patient: The healthier the patient, the more likely he is to fully participate in the treatment regimen, the prognosis may be better than the patient with many underlying diseases and/or medical conditions that do not allow it. Participating in all necessary treatments.
Patients who still have a habit of smoking after being diagnosed with laryngeal cancer: In this case, the likelihood of a second cancer will increase higher, thereby the prognosis of the disease is also worse.
How long does laryngeal cancer live?
When receiving a diagnosis of laryngeal cancer, patients will wonder how long laryngeal cancer will live? So what is the prognosis of patients with laryngeal cancer?
As mentioned earlier, the location of the tumor is one of the factors affecting the survival prognosis of patients with laryngeal cancer. We will briefly examine the regions of the larynx before getting to the specific statistics.
Laryngeal cancer is divided into 3 regions based on the location of the cancer cells, địa chỉ cắt bao quy đầu quận 10,corresponding to 3 names called epiglottitis, glottis and subglottic cancer. The incidence of laryngeal cancer by location of 3 regions is as follows: 30% to 35% in the epiglottis, 60% to 65% in the glottis and 5% in the subglottic region.
