Non-Hodgkin's lymphoma of lung

Last edited: 4/15/2026

Overview

Primary lung lymphoma (PLL) is a rare form of non-Hodgkin lymphoma that originates in the lung parenchyma, often presenting diagnostic and therapeutic challenges due to its uncommon nature 1.

Diagnosis

  • Clinical Presentation: Often asymptomatic or presents with nonspecific symptoms like cough, dyspnea, and chest pain 1.
  • Imaging: Chest CT typically shows solitary or multiple nodules, masses, or diffuse infiltrates 1.
  • Biopsy: Essential for definitive diagnosis; bronchoscopy or open lung biopsy may be required 1.
  • Histological Evaluation: Distinguishing from other pulmonary infiltrates and reactive lymphocytic processes is crucial 1.
  • Immunophenotyping: Essential for classification, often revealing B-cell origin 1.
  • Staging: PET-CT can help in staging and assessing extrathoracic involvement 1.

    • Management

  • First-Line Treatment: Chemotherapy regimens such as CHOP (Cyclophosphamide, Doxorubicin, Vincristine, Prednisone) are commonly used 1.
  • Radiation Therapy: May be considered for localized disease or consolidation after chemotherapy 1.
  • Immunotherapy: Emerging role, particularly in relapsed or refractory cases, though specific protocols are less defined 1.
  • Targeted Therapy: Limited evidence; further research needed for specific indications 1.
  • Surgical Intervention: Rarely indicated unless for diagnostic purposes or in specific complications 1.
  • Supportive Care: Focus on symptom management and supportive measures tailored to individual patient needs 1.

    • Special Populations

  • Pregnancy: Management strategies are limited; individualized care balancing maternal and fetal risks is crucial 1.
  • Elderly: Treatment decisions should consider comorbidities and functional status, often favoring less intensive regimens 1.
  • Comorbidities: Presence of significant comorbidities may influence treatment intensity and modality 1.

    • Key Recommendations

  • Definitive diagnosis requires histopathological examination via biopsy 1 (Evidence: Strong).
  • CHOP chemotherapy is a standard first-line treatment approach for PLL 1 (Evidence: Moderate).
  • Individualized management is essential, especially in special populations like pregnant women and the elderly 1 (Evidence: Expert opinion).
