Other symptoms may include fatigue, night sweats, unexplained weight loss, and frequent infections.
Diagnosing follicular lymphoma involves several tests, including a physical examination and imaging studies such as computed tomography (CT) scans or positron emission tomography (PET) scans. A biopsy, where a small sample of affected tissue is taken and examined under a microscope, is the definitive method of confirming the diagnosis.
Once follicular lymphoma is confirmed, determining the appropriate treatment plan is crucial. The specific treatment approach may depend on the stage of the disease, the patient’s overall health, and other individual factors.
Staging of Follicular Lymphoma
Follicular lymphoma is staged based on the extent of the disease’s progression and spread. The staging system helps classify the lymphoma into different categories and guides treatment decisions.
The most commonly used staging system for follicular lymphoma is the Ann Arbor staging system, which classifies the disease on a scale from stage I to stage IV:
- Stage I: The lymphoma is limited to a single lymph node region or a single organ.
- Stage II: The lymphoma involves multiple lymph node regions on the same side of the diaphragm, or it affects a single lymph node region and a nearby organ.
- Stage III: The lymphoma is present in multiple lymph node regions on both sides of the diaphragm.
- Stage IV: The lymphoma has spread to multiple organs beyond the lymph nodes, such as the bone marrow, liver, or lungs.
Understanding the stage of follicular lymphoma helps healthcare professionals determine the appropriate treatment strategy, as well as predict the prognosis or likely course of the disease.
Introduction to Bendamustine-Rituximab Protocol
With the aim of improving outcomes for patients with follicular lymphoma, the bendamustine-rituximab combination therapy has emerged as a promising treatment option.
