The WHO classification classifies large cell lung cancer as undifferentiated, squamous and glandular. But this does not make it easier for people with such a diagnosis, a malignant formation leads to death at an earlier date.
Subtypes of non-small cell cancer
The following varieties are distinguished:
The most common is the classic form, observed in 60% of patients;
Clear cell carcinoma ranks second in terms of incidence – 30%;
The neuroendocrine form is quite rare – 5%;
Giant cell carcinoma – 4%;
Infrequently, but there are cases of combined cancer – up to 4%.
It is believed that heavy tobacco smokers (up to 95% of cases) are most susceptible to non-ferrerentzirovannoy malignant formation.
Signs of the onset of the disease
The disease process at an early stage does not have pronounced symptoms, or rather, none at all. Only already at the 3rd and 4th stages the patient pays attention to such changes:
Short-term increase in body temperature;
Shortness of breath, difficulty breathing;
Hacking dry cough;
Pain in the chest;
Weakness in the body, malaise.
Prognosis of large cell lung cancer
Adenocarcinoma, as the tumor is also called, especially in advanced stages, has a disappointing prognosis – only 10-15 percent within 5 years after detection. Resection of part of the organs increases survival, and it can reach 80%.
