Summary

This study is a prospective non-randomised open label multicenter phase two study in male long-term survivors of malignant lymphoma including Hodgkin Lymphoma (HL) and Diffuse Large B-Cell Lymphoma (DLBCL). The study aims to assess whether low levels of testosterone in the blood of patients cured for aggressive lymphoma, can be effectively treated with Testosterone gel, and if treatment with testosterone can improve their general quality of life. The investigators hypothesize that patients will develop sexual dysfunction and poor quality of life when suffering from untreated 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 three questionnaires, and serum testosterone level, during one year of treatment with Testogel. The intention is to show that future follow-up visits should include focus on sexuality and serum testosterone, so relevant patients can be identified and treated for their hormonedeficiency without delay. The expected follow-up program include questionnaires and blood samples, which are easily implemented and without great cost.

Description

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 analysis of hormone levels or treatment of hypogonadism. With this study the aim is to investigate the effect and toxicity of treatment with exogenous testosterone in male long-term survivors of malignant lymphoma, to clarify whether it is relevant to include serum testosterone and potentially testosterone replacement therapy in standard follow-up programs.

Our Hypothesis:

Hypothesis 1: A significant proportion of long-term male survivors of HL and DLBCL have impaired quality of life (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.

Hypothesis 4: Substitution with testosterone in carefully selected subgroups will improve sexual function and QoL.

Hypothesis 5: Treatment with testosterone in this setting is safe with acceptable toxicity.

To assess efficacy and safety of treatment with testosterone replacement therapy on hypogonadism in lymphoma patients, blood tests and questionnaires are completed throughout one year of treatment. To assess patient sexuality and quality of life, 3 questionnaires are included; the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ C30) for general quality of life, EORTC Sexual Health Questionnaire 22 (SHQ-22) for sexual health and International index of erectile function with 5 questions (IIEF-5) for sexual function.
