Study Notes
Hodgkin Lymphoma Overview
- Stage IV Hodgkin lymphoma (HL) can be cured despite widespread disease.
- More than 80% of HL patients achieve a cure with current treatment strategies, rising to 90% in younger or early-stage patients.
- Recurrence does not preclude future cures; many patients become long-term survivors.
Treatment Goals
- Aim for a cure across all stages of HL.
- Minimize both short-term and long-term complications from treatment.
- Balance toxicity risks with treatment benefits.
Treatment Options
- Chemotherapy: Often the first line of treatment.
- Radiotherapy: Effective for early stages (IA/IIA); can be combined with chemotherapy.
- Immunotherapy: Includes monoclonal antibodies and checkpoint inhibitors.
- Stem Cell Transplantation: Considered in advanced or relapsed cases.
Chemotherapy Regimens
-
ABVD regimen:
- Adriamycin
- Bleomycin
- Vinblastine
- Dacarbazine
-
Alternative regimens:
- eBEACOPP: a more intensive combination for certain cases.
- AVD: excludes bleomycin for patients with lung issues.
- GVD: includes gemcitabine, vinorelbine, and liposomal doxorubicin.
- Treatment duration typically ranges from six to eight courses depending on disease stage.
Cytogenetic Abnormalities
- Burkitt’s Lymphoma: t(8;14) linked to C-Myc protein overexpression.
- Follicular Lymphoma: t(14;18) results in BCL-2 expression.
- Mantle Cell Lymphoma: t(11;14) leads to BCL-1 overexpression.
- Large Cell Lymphoma: characterized by BCL-6 expression.
Diagnosis and Investigations
- Histological assessment of lymph nodes is crucial for diagnosis; often confirmed with excision biopsy.
- Immunophenotyping and molecular techniques assist in accurate diagnosis.
- Common laboratory findings include normochromic normocytic anemia, elevated LDH in advanced cases, and abnormal liver functions.
- Imaging studies (CT, MRI, PET scans) are employed to assess disease extent, including nodal and extra-nodal sites.
Staging System
- Stages I-IV determine disease spread; A, B, E, S sub-classifications provide additional context.
- Category A: No B symptoms (fever, weight loss, night sweats).
- Category B: Presence of B symptoms; may necessitate more intensive treatment.
- Category E: HL cells present in extra-lymphatic tissues.
- Category S: HL cells involved in the spleen.
Incidence and Demographics
- Lymphoma incidence: 5-10 cases per 100,000 annually, with a male predominance of 3:2.
- Non-Hodgkin’s Lymphoma is twice as prevalent as Hodgkin’s Lymphoma.
Non-Hodgkin Lymphoma (NHL) Overview
- Majority of patients present with stage III or IV disease.
- Sudden transformation to aggressive diffuse tumors possible, associated with a Leukaemic phase.
- First-line treatments include single oral agents (Chlorambucil, Cyclophosphamide) or CVP (Cyclophosphamide, Vincristine, Prednisolone).
- Combination therapies may involve Fludarabine, Mitozantrone, or Rituximab (anti-CD20).
Diffuse Large B-Cell Lymphoma (DLBCL)
- Characterized by rapid progression and high-grade lymphadenopathy.
- Histologically defined by large B-cell forms (centroblasts, immunoblasts).
- Linked to 3q27 translocation and BCL-6 overexpression, offering better prognosis.
- Common across all ages, more prevalent in older adults, representing one-third of lymphomas.
- Symptoms include night sweats, fever, weight loss, and lymphadenopathy; can also affect extranodal sites (GIT, testis, brain, bone).
DLBCL Treatment Protocols
- standard treatment regimen is CHOP (Cyclophosphamide, Doxorubicin, Vincristine, Prednisolone).
- Addition of Rituximab has enhanced survival rates.
- Chemotherapy administered every 3 weeks for 6-8 cycles.
- Radiotherapy is used for bulky masses post-chemotherapy.
Complications of NHL
- Emergent complications can complicate treatment; early identification is crucial.
- Life-threatening issues include hyperleukocytosis, hypercalcemia in T-cell leukemia-lymphoma, and pericardial tamponade.
- Other complications: hyperviscosity syndrome, hepatic dysfunction, venous thromboembolism, autoimmune hemolytic anemia, and thrombocytopenia.
Prognosis and Risk Factors
- Prognosis is influenced by histopathology, disease extent, and patient condition.
- Risk classified based on scoring system: low (0-1 factors), intermediate (2 factors), poor (≥3 factors).
- Immunodeficiency predisposes patients to lymphoma and correlates with poor therapeutic response.
Follicular Lymphoma
- Most common indolent NHL associated with t(14;18) translocation and BCL-2 expression.
- Typically affects middle-aged to elderly patients, characterized by a benign course and painless lymphadenopathy.
- Imaging through CT or PET scans is standard, with lumbar puncture reserved for high CNS involvement risk.
Workup for NHL Diagnosis
- Requires lymph node/tissue biopsy for significant enlargement, persistent symptoms, or size increase.
- Immunophenotypic analysis and bone marrow biopsy may be necessary for staging.
- Utility of PET scans is increasing, minimizing the need for bone marrow aspirations.
Differential Diagnosis
- Conditions mimicking NHL symptoms include Hodgkin lymphoma, Epstein-Barr virus infection, SLE, and malignancies (e.g., nasopharyngeal carcinoma).
- Other benign conditions like toxoplasmosis and mycobacterial infections can also present similarly.
Treatment Variation for NHL
- Treatment strategy is highly individualized based on tumor stage, type, grade, and patient-specific factors such as age and overall health.
