Maximal Exercise Capacity and Extra-pulmonary Characteristics in Patients With Lung Cancer With Complete Remission .

Cardiopulmonary exercise testing (Oxygen consumption measurement during test).

The six-minute walking test (6-MWT) was used to evaluate submaximal exercise capacity.

Physical activity will be evaluated multi sensor activity monitor for 2 consecutive days.

This test was evaluated using a spirometry by which is evaluated dynamic lung functions expressed as percentages of expected values.

Respiratory muscle strength was evaluated with a mouth pressure device

Peripheral muscle strength was evaluated with a hand-held dynamometer.

The severity of dyspnea during daily living activities was evaluated using the Modified Medical Research Council (MMRC) dyspnea scale. Dyspnea is graded as follows: zero (dyspnea only with strenuous exercise), one (dyspnea when hurrying or walking up a slight hill), two (walks slower than people of the same age due to dyspnea or having to stop for breath when walking at own pace), three (stops for breath after walking 100 yards or after a few minutes) and four (too dyspneic to leave house or breathless when dressing). The minimal clinically important difference (MCID) is 1 unit for the MMRC dyspnea scale.

The Turkish version of Fatigue Severity Scale, which is a valid and reliable test, was performed to the recipients for evaluation of fatigue severity. Self-administered questionnaire is comprised of nine questions. The average score is identified on seven-point scale. Patients select a number from 1 to 7 for each 9 questions which demonstrates from strong disagreement to strong agreement, respectively. The cut-off score for fatigue severity is 36 according to this scale, if the total score obtained from this scale is higher than 36, the recipient is defined as severe fatigue.

Quality of life was measured using Turkish version of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 version 3.0 (EORTCQLQ) which is widely used as health related quality of life questionnaire in cancer patients. The cancer-specific questionnaire has 30 questions and incorporates five functional scales, three symptom scales, a global health status and several single items. All item scores are transformed to 0-100. Higher values indicate higher functional/healthy level in functional scales, a higher quality of life level in global health status and increased symptoms in symptom scales.

Montgomery Asberg Depression Rating Scale (MADRS) (Turkish version of scale) This assessment tool contains 10 items with a score from 0 to 6, thus the maximum score is 60. A higher score indicates a more severe depression.

Sleep quality of the individuals was evaluated with the Turkish version of Pittsburgh Sleep Quality Index. It is an individual evaluation scale that evaluates sleep quality and sleep disturbance in the last one month period.

The Turkish version of the Leicester Cough Scale (LÖQ) was used to assess the health-related quality of life of individuals with chronic cough. The scale evaluates chronic cough consisting of 19 items, including physical (8 items), psychosocial (7 items) and social (4 items) subsections. Each item is scored between 1 (always) and 7 (never). The total score is 3-21 points. The high scores obtained from this questionnaire, which evaluates the effect of the symptoms that have been going on for the last two weeks, show less impact on cough and lower scores indicate more impact.

Functional Assessment of Cancer Therapy - Lung cancer Quality of life questionnaire (Turkish version) is used to assess the quality of life of lung cancer patients from many cultures all over the world. It is an individual applied scale and consists of 36 questions specific to lung cancer. Body is a scale consisting of 5 subsections including status, social life and family situation, emotional state, activity status and other concerns.
