NCLEX Review Guide: Lymphoma (Hodgkin's Disease)

Definition & Classification

• Hodgkin's lymphoma is a malignant neoplasm of lymphoid tissue characterized by the presence of Reed-Sternberg cells (large, multinucleated cells with owl-eye appearance). It differs from non-Hodgkin's lymphoma by its predictable pattern of spread from one lymph node region to adjacent regions.
• The WHO classification divides Hodgkin's lymphoma into two major types: Classical Hodgkin's lymphoma (nodular sclerosis, mixed cellularity, lymphocyte-rich, and lymphocyte-depleted) and Nodular lymphocyte-predominant Hodgkin's lymphoma.

Epidemiology & Risk Factors

• Hodgkin's lymphoma has a bimodal age distribution with peaks in young adults (15-35 years) and older adults (>55 years). Males are slightly more affected than females.
• Risk factors include: family history, Epstein-Barr virus infection, immunodeficiency disorders (HIV, post-transplant), and autoimmune conditions.

Staging & Prognosis

• The Ann Arbor Staging System is used to stage Hodgkin's lymphoma: Stage I (single lymph node region), Stage II (two or more regions on same side of diaphragm), Stage III (lymph node regions on both sides of diaphragm), and Stage IV (disseminated disease in extralymphatic organs).
• Additional designations include: A (asymptomatic) or B (presence of B symptoms: fever, night sweats, weight loss), and E (extranodal involvement).

Common Symptoms

• Painless, firm lymphadenopathy is the hallmark presentation, most commonly affecting cervical and mediastinal lymph nodes. The lymph nodes often feel rubbery and may wax and wane in size.
• B symptoms include: fever >38°C (particularly Pel-Ebstein fever - cyclical fever), drenching night sweats, and unintentional weight loss >10% of body weight in 6 months.
• Other symptoms may include: fatigue, pruritus (generalized itching), alcohol-induced pain in affected lymph nodes, and symptoms related to mass effect (cough, dyspnea from mediastinal involvement).

Diagnostic Tests

• Excisional lymph node biopsy is the gold standard for diagnosis, allowing for histological identification of Reed-Sternberg cells. Fine needle aspiration is insufficient for diagnosis.
• Staging workup includes: complete blood count, comprehensive metabolic panel, erythrocyte sedimentation rate, CT scans of chest/abdomen/pelvis, PET scan, and bone marrow biopsy (for advanced stages).

Treatment Modalities

• Combination chemotherapy is the primary treatment, with ABVD regimen (Adriamycin/doxorubicin, Bleomycin, Vinblastine, Dacarbazine) being the most common protocol. Other regimens include Stanford V and BEACOPP.
• Radiation therapy may be used alone for early-stage disease or combined with chemotherapy. Involved-field radiation therapy (IFRT) targets only affected lymph node regions.
• For relapsed or refractory disease, stem cell transplantation and newer targeted therapies (brentuximab vedotin, checkpoint inhibitors like nivolumab) may be employed.

Nursing Management

1. Assessment: Monitor for treatment side effects, disease progression, and complications. Assess for B symptoms, new lymphadenopathy, and infection risk.
2. Symptom management: Implement interventions for nausea/vomiting, fatigue, myelosuppression, and other chemotherapy side effects.
3. Patient education: Provide information about disease process, treatment regimen, side effect management, and infection prevention.
4. Psychosocial support: Address anxiety, body image concerns, and fertility preservation options, especially for younger patients.
5. Long-term monitoring: Educate about importance of follow-up care to monitor for late effects of treatment and secondary malignancies.

Treatment Complications & Late Effects

• Acute complications include: myelosuppression (neutropenia, thrombocytopenia, anemia), nausea/vomiting, alopecia, mucositis, and increased infection risk.
• Late effects include: secondary malignancies (breast cancer, lung cancer), cardiovascular disease (coronary artery disease, cardiomyopathy), pulmonary fibrosis (from bleomycin), hypothyroidism (from neck radiation), and infertility.

Common NCLEX Pitfalls

• Misidentifying key symptoms: Remember that painless lymphadenopathy is the hallmark, not painful nodes (which are more common in infection).
• Confusing staging terminology: Know that Ann Arbor staging is used, and understand what each stage means for treatment planning.
• Overlooking B symptoms: Questions may focus on the significance of B symptoms (fever, night sweats, weight loss) in prognosis and staging.

NCLEX Study Strategies

• Focus on nursing process: Questions often test your ability to assess, plan, implement, and evaluate care for patients with Hodgkin's lymphoma. Prioritize safety concerns related to chemotherapy side effects.
• Practice prioritization: Know which symptoms require immediate intervention (fever in neutropenic patient, respiratory distress with bleomycin, signs of superior vena cava syndrome).
• Understand patient education: Be prepared for questions about teaching patients about side effect management, infection prevention, and follow-up care.

• Pathophysiology: Hodgkin's lymphoma is characterized by Reed-Sternberg cells and follows a predictable pattern of spread through contiguous lymph node regions.
• Clinical presentation: Painless lymphadenopathy (most commonly cervical) with possible B symptoms (fever, night sweats, weight loss).
• Diagnosis: Requires excisional lymph node biopsy for histological confirmation of Reed-Sternberg cells.
• Staging: Ann Arbor staging system (I-IV) with A/B designations for absence/presence of B symptoms.
• Treatment: Primarily ABVD chemotherapy, with or without radiation therapy, depending on stage. Advanced or refractory disease may require stem cell transplantation or targeted therapies.
• Nursing considerations: Focus on managing treatment side effects, infection prevention, patient education, and psychosocial support.
• Long-term monitoring: Surveillance for late effects including secondary malignancies, cardiovascular disease, and endocrine dysfunction.
