Patients will be interviewed by videoconferencing method at least 1 day before the operation, their first evaluation will be taken and an exercise booklet will be given.

It is a scale used to determine the severity of dyspnea with a rating of zero to 4. Zero means no dyspnea perception and 4 means severe dyspnea.

The pain, dyspnea and fatigue level of the cases were evaluated with visual analog scale (VAS) score. The scale presented as a 100 mm horizontal ruler is a documented method for scoring continuous soft data. "0" score means no pain, "100" means very severe pain

FEV1 measurements will be reported as absolute values (e.g. liters, measured) and percentage of predicted (FEV1measured/ FEV1 predicted).

FVC measurements will be reported as absolute values (e.g. liters, measured) and percentage of predicted (FVCmeasured/ FVC predicted).

DLCO and DLCO / VA values will be analyzed

Lung capacities will be given the measured value and their percentages will be calculated according to the estimated values.

Tumor side and contralateral lung V / Q scintigraphy measurements will be made.

Procalcitonin is a substance produced by many types of cells in the body, often in response to bacterial infections but also in response to tissue injury. The level of procalcitonin in the blood can increase significantly in systemic bacterial infections and sepsis.The reference value of PCT in adults and children older than 72 hours is 0. 15 ng/mL or less.

C-reactive protein is a substance produced by the liver in response to inflammation. For a standard CRP test, a normal reading is less than 10 milligram per liter (mg/L). A test result showing a CRP level greater than 10 mg/L is a sign of serious infection, trauma or chronic disease, which likely will require further testing to determine the cause

Ferritin is a blood protein that contains iron. The normal ferritin levels range from 12 to 300 nanograms per milliliter of blood (ng/mL) for males and 12 to 150 ng/mL for females.

Lactate dehydrogenase is an enzyme that helps turn sugar into energy for your cells. High LDH levels could indicate cell damage.Normal LDH levels range from 140 units per liter (U/L) to 280 U/L or 2.34 microkatals/L to 4.68 microkatals/L.

D-dimer tests are used to help rule out the presence of an inappropriate blood clot (thrombus). The reference concentration of D-dimer is < 250 ng/mL, or < 0.4 mcg/mL.

The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs. Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg.

The partial pressure of oxygen, also known as PaO2, is a measurement of oxygen pressure in arterial blood. 75 to 100 millimeters of mercury (mm Hg) is the normal ranges.

It reflects the saturation level of hemoglobin with oxygen. Its normal values are 95-100%.

The state-trait anxiety scale will determine the anxiety levels of patients before and after surgery. It is a psychological inventory based on a 4-point Likert scale and consists of 40 questions on a self-report basis. The STAI measures two types of anxiety - state anxiety, or anxiety about an event, and trait anxiety, or anxiety level as a personal characteristic.While evaluating, a score between 1 (or -1) and 4 (or -4) is given for each item according to the positive or negative characteristics of the item, and the total score to be obtained is 50 constant is added. The highest score is 80, the lowest is 20. Total anxiety the higher the score, the more anxiety level of the person filling the scale.
