What is the most important prognostic factor in lung cancer?

According to the literature, performance status, stage-tumor dimension and nodal status, weight loss, were the most important prognostic factors for survival in patients with locally advanced non-small cell lung cancer.

What determines prognosis of lung cancer?

Your outcome depends on the type of lung cancer that you have and also the stage of the cancer when it was diagnosed. This means how big it is and whether it has spread. Your general health and fitness might also affect survival. Doctors call this your performance status.

What is the most important prognostic factor?

The most important prognostic factors include the following : Thickness and/or level of invasion. Mitotic index (mitoses per millimeter) Ulceration or bleeding at the primary site.

Which lung cancer has best prognosis?

It is increasing in frequency and is more common in women. People with this type of lung cancer tend to have a better prognosis than those with other types of lung cancer. Squamous cell carcinomas were formerly more common than adenocarcinomas; today, they account for about 25% to 30% of all lung cancer cases.

Which lung cancer has worse prognosis?

The ACS estimate the following 5-year survival rates for people with small cell lung cancer: for localized cancer: 29% for regional cancer: 15% for distant cancer: 3%

Which lung cancer has the best prognosis?

What are the prognosis levels?

A prognosis may be described as excellent, good, fair, poor, or even hopeless. Prognosis for a disease or condition is largely dependent on the risk factors and indicators that are present in the patient.

What is poor prognostic factors?

So far, there is no uniform definition of poor prognostic factors. Factors that are used predominantly for treatment decisions are high disease activity, the early presence of erosions, and autoantibody positivity [3, 4]. These factors are acknowledged to be of importance for the course of RA [2].

What is a poor prognostic factor?

Factors that predict a better outcome are called ‘good’ or ‘favorable’ prognostic factors. Those that predict for worse outcomes are called ‘poor’ prognostic factors. For some diseases and conditions, such as non-Hodgkin lymphomas, the factors are scored to give a prognostic index.

What is a prognostic biomarker?

Explanation. A prognostic biomarker is one that indicates an increased (or decreased) likelihood of a future clinical event, disease recurrence or progression in an identified population. Prognostic biomarkers are measured at a defined baseline, which may include a background treatment.
