C84.70
Anaplastic large cell lymphoma, ALK-negative, unspecified site
Clinical Classification Guidelines
Medical Intelligence & Overview
Anaplastic large cell lymphoma, ALK-negative (ICD-10 Code C84.70), is a type of non-Hodgkin lymphoma that originates in the lymphatic system. This form of lymphoma is characterized by the absence of the anaplastic lymphoma kinase (ALK) protein, which helps distinguish it from other similar lymphomas. It can affect various parts of the body, such as lymph nodes and other tissues, and requires specialized diagnosis and treatment strategies.
Causes & Symptoms
Clinical Causes: Genetic mutations and chromosomal abnormalities that occur spontaneously Previous exposure to certain chemicals or radiation Immune system dysfunction or suppression Age and geographic factors may also play a role, although specifics are not well established Potential unknown environmental or lifestyle factors
Key Symptoms: Swollen lymph nodes, often painless Unexplained weight loss Fever that persists over time Night sweats Fatigue or weakness Unexplained pain or discomfort in affected areas Localized swelling or mass that may be visible or palpable
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination: Assessment of symptoms and physical signs Imaging tests such as PET scans or CT scans to locate and evaluate lymphoma involvement Biopsy of affected tissue to examine the cells microscopically and confirm diagnosis Immunohistochemistry tests to detect specific protein markers essential for differentiating ALK-negative from ALK-positive types Molecular genetic testing to identify genetic abnormalities Blood tests to assess overall health status and organ function
Treatment Protocols: Chemotherapy: Often the primary treatment, using drugs such as CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) and others Immunotherapy: Targeted therapies that help the immune system recognize and combat lymphoma cells Radiation therapy: May be used in localized cases to target specific areas Stem cell or bone marrow transplantation: Considered in certain cases to replace diseased or damaged cells Supportive care: Managing symptoms and side effects, maintaining nutritional health, and improving quality of life
