This study aims to evaluate the effects of a 12-week aerobic and resistance exercise program in cancer patients with cachexia compared to standard care. A total of 40 participants aged 18 to 65, diagnosed with gastrointestinal cancer and cachexia, will be included in the study. Participants will be randomly assigned to the exercise group (aerobic and resistance training) or the control group (standard care), with 20 individuals in each group. Before the 12-week intervention, both the exercise and control groups will undergo evaluations. Demographic and clinical data will be recorded. The following assessments will be conducted: Body Composition: Bioelectrical impedance analysis Sarcopenia Assessment: SARC-F questionnaire Functional Exercise Capacity: 6-minute walk test Gait Parameters: 8-meter walk test Mobility and Balance: Timed Up and Go test Muscle Strength: Knee extensor and hand grip strength measured with dynamometers 30-second sit-to-stand test Additionally, participants will complete several questionnaires, including the Edmonton Symptom Assessment Scale, Karnofsky Performance Status scale, FRAIL scale, Fatigue Severity Scale, and EORTC-QLQ30. The exercise group will participate in a supervised and home-based exercise program consisting of aerobic and resistance exercises over 12 weeks. The intensity will be progressively adjusted based on the individual's perceived exertion.
Cancer cachexia is a multifactorial syndrome characterized by progressive functional impairment and loss of skeletal muscle mass, which does not improve with nutritional support. This study aims to evaluate the effects of a 12-week aerobic and resistance exercise program in cancer patients with cachexia compared to standard care. A total of 40 participants aged 18 to 65, diagnosed with gastrointestinal cancer and cachexia, will be included in the study. Participants will be randomly assigned to the exercise group (aerobic and resistance training) or the control group (standard care), with 20 individuals in each group. The study will be single-blind, meaning the outcome assessor will not know which group the participants belong to. Before the 12-week intervention, both the exercise and control groups will undergo evaluations. Demographic and clinical data will be recorded. The following assessments will be conducted: Body Composition: Bioelectrical impedance analysis Sarcopenia Assessment: SARC-F questionnaire Functional Exercise Capacity: 6-minute walk test Gait Parameters: 8-meter walk test Mobility and Balance: Timed Up and Go test Muscle Strength: Knee extensor and hand grip strength measured with dynamometers 30-second sit-to-stand test Additionally, participants will complete several questionnaires, including the Edmonton Symptom Assessment Scale, Karnofsky Performance Status scale, FRAIL scale, Fatigue Severity Scale, and EORTC-QLQ30. The exercise group will participate in a supervised and home-based exercise program consisting of aerobic and resistance exercises over 12 weeks. Supervised Aerobic Exercises: Conducted every two weeks, three days a week. Supervised Resistance Exercises: Conducted every two weeks on consecutive days. On weeks without supervised exercises, participants will follow a home exercise program that includes breathing exercises, walking for 20-30 minutes, and resistance exercises. The supervised aerobic exercises will consist of 20 minutes on a treadmill at a heart rate corresponding to 55-75% of the Karvonen formula. Warm-up and cool-down will be performed at 30-40% of the Karvonen heart rate for 5 minutes. Resistance training will involve 12 different exercises targeting major muscle groups, using body weight and resistance bands, at an effort level of 5-7 on the Borg scale, with 8-12 repetitions and 1-3 sets. The intensity will be progressively adjusted based on the individual's perceived exertion.

Time frame: At baseline and after 12 weeks of exercise training
Weight Assessment
Weight change in a certain period and percentage of initial weight are used to determine weight loss. Weight loss of 5%, 10% or 20% in a certain period is associated with an increased risk of malnutrition. The participants' weights will be recorded in kilograms.
Time frame: At baseline and after 12 weeks of exercise training
Height Assessment
The participants' heights will be recorded in centimeters.
Time frame: At baseline and after 12 weeks of exercise training
Body Mass Index Assessment Body Mass Index Assessment
The participants' Body Mass Index (BMI) values will be recorded in kg/m² (kilograms per square meter).
Time frame: At baseline and after 12 weeks of exercise training
Assessment of Muscle Strength
Quadriceps femoris muscle strength will be evaluated using a digital dynamometer (Lafayette, USA). The tests will be performed in the sitting position. Muscle strength will be tested in the middle of the joint range of motion, and the maximum isometric contraction will be measured for 5 seconds. The muscle strength measurement will be repeated 3 times on the right and left sides, and the best value obtained will be recorded in kilograms (kg). Hand grip strength will be measured with a hydraulic dynamometer (Jamar, Sammons Preston Rolyan, Chicago, USA). The test will be performed while patients are sitting comfortably with the shoulder adducted, the forearm neutrally rotated, the elbow flexed 90° and the forearm and wrist in a neutral position. Patients will be instructed to perform a maximum isometric contraction. The participants' hand grip strengths will be recorded in kilograms.
Time frame: At baseline and after 12 weeks of exercise training
Assessment of Lower Extremity Performance
Lower extremity performance will be evaluated with a 30-second sit-to-stand test, in which the number of times a person can sit down and stand up in 30 seconds is recorded.
Time frame: At baseline and after 12 weeks of exercise training
Sarcopenia Assessments
The steps determined by ESWGOP will be followed in sarcopenia screening. The 5-question SARC-F questionnaire is a rapid screening questionnaire used in sarcopenia assessment. Responses are scored between 0-2 and the total score is between 0-10. A total score of 4 or more indicates the presence of a risk for sarcopenia.
Time frame: At baseline and after 12 weeks of exercise training
Assessment of Muscle and Fat Mass
Bioelectrical impedance analysis (Inbody 720) will be used for muscle and fat mass assessment. Participants' muscle and fat mass will be recorded in kilograms.
Time frame: At baseline and after 12 weeks of exercise training
Mobility, balance and performance assessment
For mobility, balance and performance assessment; Timed Up and Go test (TUG) will be used. TUG will be performed by standing up from a chair (sitting height 46 cm), walking 3 m to a line marked on the floor, crossing the line, turning around and walking back, and sitting on a chair. For TUG-cognitive, the individual will be instructed to count backwards by 3 from a random number between 20 and 100 while completing the TUG. The number will be given immediately after the researcher says "go", and errors in subtraction will not be corrected. In TUG-manual, the individual will be asked to pick up and carry a glass full of beans without spilling while completing the TUG. The glass will be placed on a solid surface 90° to the right of the individual while they are sitting, and they will be asked to put the glass back in the same spot before sitting down again.
Time frame: At baseline and after 12 weeks of exercise training
Assessment of Functional Exercise Capacity
A 6-minute walk test (6 MWT) will be used to assess functional exercise capacity. Participants will be asked to walk as fast as possible on a 30-meter straight corridor in the 6 MWT and the distance covered will be recorded in meters. During 6 MWT, walking distance, speed and cadence will be assessed using a wireless motion detection device (G-Walk, BTS Bioengineering SpA, Italy) attached to the individual's waist using a semi-elastic belt over L4-L5.
Time frame: At baseline and after 12 weeks of exercise training
Assessment of Gait Parameters
Individuals will be asked to walk as naturally as possible along an 8-meter path at a speed of their own choosing to assess the time-distance parameters of walking. The 8-meter walk test will measure the time-distance parameters of gait, including step length, stance and swing phases, single support and double support phases. During 8-meter walk test, walking distance, speed, cadence and time-distance parameters of gait will be assessed using a wireless motion detection device (G-Walk, BTS Bioengineering SpA, Italy) attached to the individual's waist using a semi-elastic belt over L4-L5.
Time frame: At baseline and after 12 weeks of exercise training
Performance Assessment
Functional status will be assessed using the Karnofsky Performance Status (KPD) scale. It is considered the gold standard of performance measurement for cancer patients. Individuals will rate their functional status using the KPD scale, which ranges from 30 (I feel severely disabled and need to be hospitalized) to 100 (I feel normal; I have no complaints or symptoms). In the literature, it is generally accepted that individuals who score 70 points and above have adequate functional status. This score indicates that the individual is at a level where they can care for themselves, but their normal activity has decreased and they are unable to do active work.
Time frame: At baseline and after 12 weeks of exercise training
Evaluation of Symptoms
The Edmonton Symptom Assessment Scale will be used to evaluate the symptoms of participants in both groups. The symptoms included in the scale are pain, fatigue, drowsiness, nausea, loss of appetite, dyspnea, depression, anxiety, feeling unwell and other problems. The severity of each symptom is scored between 0 and 10. A score of 0 indicates no symptoms, while a score of 10 indicates that the symptom is felt very severely.
Time frame: At baseline and after 12 weeks of exercise training
Frailty Assessment
Morley et al. found that the five-item 'FRAIL Scale' was effective in detecting frailty. In addition to the patient's general health status, the questionnaire evaluates with questions about comorbidities; patients receive zero or one point according to the answer given for each question. A total of 0 is considered normal (non-frail), 1-2 is pre-frail and a score of \>2 is frail. The validity and reliability of the questionnaire in Turkish was demonstrated by Hymabaccus et al. in 2017.
Time frame: At baseline and after 12 weeks of exercise training
Assessment of Cancer-Related Fatigue
The Fatigue Severity Scale (FSS) will be used to assess the participants' level of cancer-related fatigue. FSS is a scale consisting of 9 questions that assess fatigue. Each item is scored between 0 and 7. The total score is divided by 9 and if the mean is \<4, it is assessed as no fatigue, if \>4, it is assessed as fatigue. The FSS Turkish form, which has been validated and validated as reliable, will be used.

Assessment of Quality of Life
Quality of life will be assessed using the 30-item European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ30). The EORTC QLQ-C30 is a valid and reliable cancer-specific quality of life scale. The scale includes three subheadings and 30 questions: general health, functional and symptom scales. In the first 28 questions showing the functional and symptom scales, there are four-point Likert options for each question: not at all (1 point), a little (2 points), quite a bit (3 points), and a lot (4 points). In the 29th question of the scale, the patient is asked to score their health from 1 to 7 (1: very poor and 7: excellent); and in the 30th question, they are asked to evaluate their general quality of life. The scores obtained from all questions of the scale range from 0 to 100 points.
