Testicular Cancer: Signs, Remedies, Potential Hazards, and Further Details
Testicular lymphoma, a type of non-Hodgkin lymphoma (NHL), is an uncommon form of cancer that originates in the lymphatic system, which is part of the immune system. This article aims to provide an overview of testicular lymphoma, its risk factors, symptoms, and treatment options.
Risk Factors
Testicular lymphoma mainly affects older men, typically those over 60 years old. Other risk factors include immunodeficiency conditions such as HIV, organ transplantation, or autoimmune diseases. Secondary testicular lymphoma occurs in patients with preexisting systemic lymphoma who develop testicular involvement. Certain viral infections, like Epstein-Barr virus (EBV), are associated with some diffuse large B-cell lymphomas, a common subtype affecting testicular tissue. Germinal center B-cell abnormalities can also lead to lymphomagenesis, including in testicular lymphomas.
Symptoms
The symptoms of testicular lymphoma often include a painless swelling or mass in one testicle, testicular discomfort or enlargement. Occasionally, systemic "B symptoms" such as fever, night sweats, and unexplained weight loss may appear. If secondary, symptoms related to systemic lymphoma including lymphadenopathy and organomegaly may appear.
Diagnosis
A testicular ultrasound may be performed if a healthcare professional suspects a tumor. Blood tests can be ordered to test for tumor markers in the diagnosis of testicular lymphoma. Doctors usually avoid biopsy when diagnosing testicular lymphoma due to the risk of spreading the cancer.
Treatment
Because testicular lymphoma is aggressive and can relapse in the central nervous system and contralateral testis, a combined modality treatment approach is typically required. Standard multiagent chemotherapy regimens based on diffuse large B-cell lymphoma protocols, often including rituximab (an anti-CD20 monoclonal antibody), are used. Localized radiation to the affected testis and sometimes to the contralateral testis to reduce relapse risk may also be employed. Intrathecal chemotherapy is administered to prevent or treat central nervous system involvement, which is common in testicular lymphoma. In relapsed or refractory cases, a stem cell transplant may be considered.
In children, testicular relapse of leukemia (extramedullary relapse) is treated with chemotherapy, intrathecal chemo, and radiation to the testis.
Prognosis
The outlook for testicular lymphoma depends on several factors, including the size of the tumor, the stage of the cancer at diagnosis, age, presence of other symptoms, spread of cancer to other sites, and which testicle the lymphoma occurs in (lymphoma in the left testicle may worsen the outlook). Testicular lymphoma has a higher 5-year survival rate if diagnosed at an early stage and treated appropriately.
Advanced Treatments
Chimeric antigen receptor (CAR) T-cell therapy is a form of immunotherapy used to treat testicular lymphoma, with approved therapies including Kymriah (tisagenlecleucel) and Yescarta (axicabtagene ciloleucel).
In conclusion, testicular lymphoma is a rare but aggressive form of cancer that requires prompt diagnosis and comprehensive treatment. Understanding its risk factors, symptoms, and treatment options can aid in early detection and effective management.
