Hematologic malignancies are neoplasms that affect the blood, bone marrow, and lymph nodes. Hematological malignancies are the most common forms of leukemia, lymphoma, and myeloma, with numerous subtypes. The general symptoms of leukemia are fatigue, increased susceptibility to infection, bleeding, and the formation of bruises easily. Typical lymphoma symptoms are night sweats and involuntary weight loss, recurrent fever, fatigue, and itching. Myeloma patients often have bone pain, fatigue, anemia, hypercalcemia or infection symptoms.

Adverse effects of hematologic malignancies and treatments cause abnormality in physical function and quality of life. Treatments such as chemotherapy, radiotherapy and hematopoietic stem cell transplantation, which may have side effects on the body systems are used in early or late period. The most common side effect due to chemotherapy is fatigue. Vomiting, weight loss, anemia, depression, decreased aerobic capacity, loss of muscle strength, decreased physical functioning and deterioration in the quality of life are indirect side effects seen in patients.

In the literature, side effects of hematological malignancies have been investigated after treatment in patients. However, no study investigated exercise capacity, quality of life, physical activity level and pulmonary functions on newly diagnosed hematologic malignant patients. Therefore, the investigators aimed to compare aforementioned outcomes in newly diagnosed hematologic malignant patients and healthy controls.

According to sample size calculation 30 newly diagnosed hematologic malignant patients and 30 healthy individuals will be included. Before treatment submaximal exercise capacity, physical activity, quality of life, pulmonary functions, respiratory and peripheral muscle strength, respiratory muscle endurance, dyspnea and fatigue perception, anxiety and depression will be evaluated. Primary outcome measurements are exercise capacity, physical activity, quality of life, secondary outcomes are respiratory and peripheral muscle strength, respiratory muscle endurance, pulmonary functions, dyspnea and fatigue perception, anxiety and depression.

Inclusion Criteria:

• Newly diagnosed hematological malignant patients
• 18-65 years of age
• under standard medications.

Exclusion Criteria:

• having cognitive disorder,
• orthopedic or neurological disease with a potential to affect functional capacity,
• comorbidities such as asthma, chronic obstructive pulmonary disease (COPD), acute infections or pneumonia,
• problems which may prevent evaluating such as visual problems and mucositis
• having metastasis to any region (bone etc.)
• having acute hemorrhage in the intracranial and / or lung and other areas
• having any contraindication to exercise training

Hospitalized patients and healthy volunteers

There is not a plan to make individual participant data but when the statistical analyses of all data are made, all results will be shared.
