What are the long-term side effects of Hodgkin lymphoma treatment?

Long-term side effects of Hodgkin lymphoma treatment can appear months or years after treatment ends, and these effects vary significantly between individuals. These effects include heart and lung problems, changes in the digestive system, impacts on the reproductive and endocrine systems, as well as bone, hearing, and vision problems. These effects depend on the type of treatment and its dosage, the patient's age, and the area of the body treated [4].

Understanding Long-Term Side Effects

Long-term side effects are health problems that may appear months or years after cancer treatment ends. These problems are specific to certain types of treatments and doses that the patient received. Long-term side effects vary significantly from person to person, even if they have the same type of cancer and treatment. It is important to discuss potential side effects with the doctor while planning for care and follow-up [4].

Effects on Different Body Systems

Hodgkin lymphoma treatment can affect several systems in the body:

• Heart problems: Some chemotherapy drugs and chest radiation therapy may cause heart problems that do not appear until years after treatment. These problems may include heart muscle weakness (congestive heart failure) or coronary artery disease, where the small blood vessels that supply the heart with blood and oxygen narrow [4].
• Lung problems: Chemotherapy and chest radiation therapy may lead to lung damage, and problems may not appear until years later. Survivors who received both chemotherapy and chest radiation may be at a higher risk for lung damage, which causes shortness of breath or a dry cough [4].
• Digestive system problems: Radiation therapy to the abdomen and pelvis can cause damage to the intestines and rectum, leading to problems such as chronic radiation enteritis or chronic radiation proctitis after months or years. Symptoms may include chronic diarrhea with mucus, difficulty digesting and absorbing nutrients, anemia, and weight loss [4].
• Changes in the reproductive and endocrine systems: Some cancer drugs and radiation can damage parts of the endocrine system, such as the thyroid gland, ovaries, and testicles. This may lead to problems such as early menopause, infertility, hypothyroidism, and weight gain [4]. For females, cancer treatments can affect fertility by damaging the ovaries or causing primary ovarian insufficiency, which may lead to early menopause or infertility [5].
• Bone and joint problems: Chemotherapy, steroid medications, hormonal therapy, or radiation therapy may cause bone thinning. With radiation therapy, bone loss occurs only in the treated part of the body. Radiation therapy, some chemotherapy drugs, and steroids can also cause scar tissue formation in the joints, leading to loss of movement [4].
• Hearing and vision problems: Some chemotherapy drugs (especially cisplatin) and high doses of radiation to the brain can cause tinnitus or hearing loss that begins months or years after treatment. Some cancer treatments may also increase the risk of developing cataracts or dry eye syndrome [4].

The Importance of Follow-up and Post-Treatment Care

Regular medical follow-up is vital for Hodgkin lymphoma survivors. Periodic check-ups help in the early detection of any long-term side effects and managing them effectively. Patients should discuss any new or persistent symptoms with their doctors, such as severe fatigue, shortness of breath, or joint pain, as early intervention can significantly improve outcomes [4]. Follow-up may include physical examinations, blood tests, and imaging assessments to monitor various organ functions [2].
