Laboratory aspects of cancer

Area of Science:

• Oncology
• Hematology
• Nephrology

Background:

• Neoplastic diseases frequently manifest with systemic complications beyond primary tumor sites.
• Hematologic and biochemical alterations are common, necessitating careful monitoring in cancer patients.

Purpose of the Study:

• To review the spectrum of non-neoplastic hematologic and systemic alterations associated with cancer.
• To highlight key diagnostic considerations for paraneoplastic syndromes.

Main Methods:

• Literature review of hematologic and systemic manifestations in neoplastic disease.
• Analysis of common laboratory and pathological findings in cancer patients.

Main Results:

• Hematologic changes include polycythemia, anemia, leukocytosis/leukopenia, thrombocytosis/thrombocytopenia, and coagulopathies.
• Metabolic disturbances such as hypercalcemia and nephrotic syndrome can occur.
• Examination of effusions for malignancy and monitoring of serum globulin and enzyme levels are crucial.

Conclusions:

• Cancer-associated hematologic and systemic changes are diverse and require comprehensive evaluation.
• Recognizing these paraneoplastic syndromes is vital for accurate diagnosis and patient management.
