Realistic Medical Report for a Non-Hodgkin Lymphoma Patient After Radiation and Targeted Therapy

A comprehensive medical report for a patient with Non-Hodgkin lymphoma who has undergone radiation and rituximab therapy should include detailed diagnostic information, treatment history, response assessment, and follow-up plans.

Patient Information and Diagnosis

• Patient diagnosed with diffuse large B-cell non-Hodgkin lymphoma (DLBCL), confirmed by excisional lymph node biopsy with immunohistochemistry showing CD20 positivity 1, 2
• Diagnosis established according to the World Health Organization classification 1
• Initial staging performed using Ann Arbor system with International Prognostic Index (IPI) calculation 1
• Pre-treatment workup included complete blood count, LDH, uric acid, HIV screening, hepatitis B and C screening 1
• CT scan of chest and abdomen performed for initial staging, with bone marrow aspirate and biopsy 1
• PET scan used for accurate baseline assessment and delineation of disease extent 1, 3

Treatment Details

• Patient received R-CHOP regimen (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) 1
• Rituximab administered at 375 mg/m² per cycle 1, 4
• Total of 6 cycles of R-CHOP given every 14 days with growth factor support 1
• Involved-site radiation therapy delivered to areas of initial bulky disease 1, 5
• Radiation dose of 30 Gy administered using modern techniques including intensity-modulated radiation therapy to minimize normal tissue damage 5
• Prophylactic measures taken to prevent tumor lysis syndrome due to high tumor burden 1

Treatment Response Assessment

• Interim response evaluation performed after 3-4 cycles using CT scan 1
• End-of-treatment assessment included CT scan and PET scan 1, 2
• Response classified according to revised response criteria incorporating PET findings 1, 2
• Bone marrow biopsy repeated at end of treatment as it was initially involved 1
• Complete metabolic response achieved on final PET scan 2

Treatment Toxicity and Complications

• Infusion-related reactions to rituximab documented during first infusion, consisting of fever, chills, and hypotension, managed with slowing of infusion and supportive care 4
• Grade 2 neutropenia observed after cycle 4, not requiring dose reduction 1, 4
• Radiation-induced skin changes noted in the irradiated area, resolved with topical management 5
• No evidence of significant late toxicity at 6-month follow-up 2

Follow-up Plan

• History and physical examination scheduled every 3 months for first year, every 6 months for 2 more years, then annually 1, 2
• Blood count and LDH monitoring at 3,6,12, and 24 months 1, 2
• CT scans scheduled at 6,12, and 24 months after completion of treatment 1, 2
• Routine surveillance with PET scan not recommended 1, 2
• Thyroid function tests scheduled at 1,2, and 5 years due to radiation exposure to the neck 1, 3
• Monitoring for secondary malignancies, particularly breast cancer screening for women who received chest radiation at a young age 1

Prognosis and Future Considerations

• Patient currently in complete remission with excellent prognosis 2
• Risk of relapse highest in first two years after treatment 2
• In case of relapse, salvage therapy options would include R-DHAP, R-ICE, or R-ESHAP followed by high-dose therapy with stem cell support if patient remains eligible 1, 2
• Alternative options in case of rituximab resistance would include radioimmunotherapy with agents like ibritumomab tiuxetan 6, 7
• Long-term monitoring required for late effects of therapy including secondary malignancies 1, 2
