This study is an observational cross-sectional study which aims to investigate the relationship between treatment with chemotherapy and the development of low levels of testosterone in the blood in patients cured for aggressive lymphoma. We hypothesize that patients in turn will develop sexual dysfunction and poor quality of life because of this reduced level of testosterone. Cancer treatment is increasingly effective and the overall survival higher, which makes issues like sexuality and long-term quality of life more and more important to address in cured cancer patients. Patient sexuality and quality of life is measured by 3 questionnaires filled out once, and serum testosterone by a single blood sample. We hope to show that future follow up visits should include focus on sexuality and serum testosterone. Questionnaires and blood samples can be implemented easily and without great cost.


Diffuse large B-cell lymphoma and Hodgkin Lymphoma are two aggressive lymphomas often treated with doxorubicin containing chemotherapy. Doxorubicin is an anthracycline and is known to be toxic to both Leydig Cells of the testes and hormone-producing cells of the hypothalamus. Therefore patients treated with this drug are at risk of developing hypogonadism. Standard follow-up programs do not include investigation of hormone levels. With this study we aim to investigate the extent of hypogonadisme in patients treated with anthracycline containing chemotherapy, to clarify whether it is relevant to include serum testosterone in standard follow-up programs.

Our Hypothesis:

Hypothesis 1: A significant proportion of long-term male survivors of HL and DLBCL have impaired QoL due to sexual dysfunction.

Hypothesis 2: A significant proportion of long-term male survivors of HL and DLBCL have reduced levels of testosterone.

Hypothesis 3: A significant relationship between QoL, sexual dysfunction and testosterone levels exists.

To clarify the extent of hypogonadisme a single blood test including s-total-testosterone will be drawn once, and levels below 8nmol/L will be classified as hypogonadisme. To assess patients sexuality and quality of life, 3 questionnaires will be filled out; the EORTC QLQ-C30 for general quality of life, EORTC SHQ-22 for sexual health and IIEF-5 for sexual function.
