[Diagnosis of malignant lymphomas]

Area of Science:

• Hematology-Oncology
• Pathology
• Clinical Diagnostics

Context:

• Malignant lymphomas necessitate a distinction between initial morphological diagnosis and extended staging for treatment planning.
• Enlarged diagnostic procedures, including histopathological assessment, are vital for determining disease spread and patient grouping.
• Prompt morphological evaluation of adult lymph node swellings within three weeks is essential for early diagnosis.

Purpose:

• To outline the diagnostic pathway for malignant lymphomas, emphasizing early detection and comprehensive staging.
• To highlight the importance of interdisciplinary collaboration in lymphoma diagnosis and classification.
• To guide the timely initiation of appropriate therapy based on accurate staging and patient stratification.

Summary:

• Distinguishes between primary morphological diagnosis and extended diagnostics for malignant lymphomas, including staging and activity assessment.
• Recommends prompt morphological clarification of lymphadenopathy in adults and exclusion of abdominal lymphogranulomatosis in cases of unexplained fever.
• Advocates for explorative laparotomy and splenectomy before treatment, with exceptions for cytostatic pre-treatment in high-risk cases.
• Stresses that clinical staging requires an interdisciplinary approach within a hematologic-oncologic center.
• Underscores the necessity of internist evaluation for the Kiel classification of non-Hodgkin lymphomas to optimize therapy.

Impact:

• Ensures timely and accurate diagnosis of malignant lymphomas, leading to improved patient outcomes.
• Facilitates optimal therapeutic strategies through comprehensive staging and classification.
• Promotes a collaborative, interdisciplinary approach to lymphoma management.
