Cancer type, time since diagnosis and duration of the clinical examination
Three studies included mixed diagnosis; i.e., one study being an audiologic evaluation of cancer survivors who had received platinum-based chemotherapy [10], another conducting a sperm analysis [29], and the last performing a cardiac Magnetic Resonance Imaging on survivors who had received anthracyclines [22]. Five studies included patients with previous hematologic malignancies with an examination duration of more than three hours and a median follow-up time of more than ten years. Studies on solid tumors had shorter duration and either a long or missing follow-up time.
