Study Notes
Hodgkin Lymphoma: A Case Study
- Patient Case Overview: A 30-year-old male presented with a painless, enlarged lymph node in the right cervical region, persisting for two months. He experienced fatigue, intermittent fevers, and night sweats. Physical examination revealed firm, non-tender lymphadenopathy. Biopsy confirmed Hodgkin lymphoma, with involvement limited to the neck and chest. Treatment options, including chemotherapy and radiotherapy, were discussed.
Short Essay Questions
-
Epidemiology and Risk Factors: Hodgkin lymphoma is more common in young adults, especially males, and may be associated with Epstein-Barr virus (EBV) infection and family history.
-
Pathophysiology and Treatment Implications: The pathophysiology involves the transformation of B lymphocytes, leading to the characteristic Reed-Sternberg cells. This impacts treatment response as different types of Hodgkin lymphoma have varying responses to different treatments.
-
Staging System and Clinical Significance: The Ann Arbor staging system, ranging from I to IV, is used to determine the extent of the disease, influencing treatment decisions and prognosis. Staging considers the location and spread of lymph nodes.
-
First-Line Treatment Options: First-line treatments typically include ABVD chemotherapy, which may be supplemented with radiation therapy, depending on the stage of the disease.
-
Follow-Up and Surveillance: Regular follow-up is crucial to monitor recurrence and manage long-term effects of treatment, including secondary malignancies.
Multiple Choice Questions
-
Classic Histological Finding: Reed-Sternberg cells are a classic histological finding in Hodgkin lymphoma.
-
EBV Association: Nodular sclerosis is the Hodgkin lymphoma subtype most commonly associated with EBV infection.
What is the most common initial presentation of Hodgkin lymphoma in patients?
- Painless lymphadenopathy
Which stage of Hodgkin lymphoma involves two or more lymph node regions above the diaphragm?
- Stage II
What is the role of PET-CT in the management of Hodgkin lymphoma?
- Staging and treatment response evaluation
Which chemotherapy regimen is the standard first-line treatment for Hodgkin lymphoma?
- ABVD
Which symptom is considered a “B symptom" in Hodgkin lymphoma?
- Night sweats
What factor significantly improves prognosis in early-stage Hodgkin lymphoma?
- Absence of B symptoms
Which immune checkpoint inhibitor is used for relapsed Hodgkin lymphoma treatment?
- Pembrolizumab
Which subtype of Hodgkin lymphoma has the best overall prognosis?
- Nodular sclerosis
Case Scenario
- A 30-year-old male presented with a painless, enlarged lymph node in the right cervical region, persistent for two months. He also reported fatigue, intermittent fevers, frequent night sweats, and a 5% unintentional weight loss over the past month. Physical examination revealed firm, non-tender lymphadenopathy.
Clinical Examination
- Vital Signs: Blood pressure 120/80 mmHg, heart rate 80 beats per minute, temperature 37.8°C
- Physical Examination: Enlarged, non-tender lymph nodes palpable in the cervical region, no hepatosplenomegaly.
Analysis of the case
- Possible causes of lymphadenopathy in a young adult
- Importance of thorough clinical examination in lymphadenopathy cases
- Factors distinguishing Hodgkin lymphoma from other lymphomas and non-malignant causes
- Diagnostic tests to confirm Hodgkin lymphoma and determine staging
Evaluation of Lymphadenopathy
- Age (less than 30: benign; older than 50: more malignant)
- Location (examine drainage areas; generalized lymphadenopathy suggests systemic disease)
- Associated symptoms (presence or absence of splenomegaly)
- Duration (longer duration may indicate chronic infection or indolent cancer)
- Physical examination (size, pain/tenderness, consistency)
Matting
- Benign or malignant, location is considered to determine whether it's malignant
Preliminary Assessment
- Painless lymphadenopathy + B symptoms = high suspicion for Hodgkin lymphoma
- Other possible diagnoses include non-Hodgkin lymphoma and infectious/inflammatory causes.
B symptoms
- Fever (unexplained fevers above 38°C)
- Night sweats (require a change of bedclothes)
- Weight loss (unintentional, 10% of body weight in 6 months or less)
Diagnostic Workup
- Complete blood count (CBC)
- Erythrocyte sedimentation rate (ESR)
- Lactate dehydrogenase (LDH)
- Chest X-ray and CT scan of the neck and chest
- Excisional biopsy of the enlarged lymph node
- Referral to an oncologist for management, possible bone marrow biopsy, and PET scan.
Lab Results
- CBC: Mild anemia and lymphopenia
- ESR: Elevated
- Biochemical tests: Liver and renal function tests within normal limits
Microscopic Findings
- Reed-Sternberg cells are distinctive neoplastic giant cells, often appearing with a "owl-eye" appearance.
- Different variants of Reed-Sternberg cells (mononuclear, lacunar, lymphohistocytic) are associated with various subtypes of Hodgkin lymphoma.
Hodgkin Lymphoma Classification
- Classical Hodgkin lymphoma subtypes (Nodular sclerosis, Mixed cellularity, Lymphocyte-rich, Lymphocyte-depleted)
- Nodular lymphocyte-predominant Hodgkin lymphoma
Staging
- Ann Arbor staging system (stages I-IV)
Prognosis
- Depends on the patient's age, clinical stage, and absence of B symptoms (presence may indicate more advanced stages).
Differences Between Hodgkin and Non-Hodgkin Lymphomas
- Incidence, sites, distribution
- Microscopic appearance (Reed-Sternberg cells, other features).
