Interpreting Hematology Results for Cancer Diagnosis

As a hematologist, the detection of cancer is one of the integral parts of your job. Hematology results can provide clues about the presence of cancer in patients. However, interpreting these results is not a straightforward process. Here, we discuss seven crucial subtopics to keep in mind when interpreting hematology results in cancer diagnosis.

Seven Key Subtopics

  • CBC test results
  • Peripheral blood smear analysis
  • Platelet count, morphology, and function
  • Bone marrow examination
  • Immunophenotyping
  • Flow cytometry analysis
  • Cytogenetic testing

CBC Test Results

A complete blood count (CBC) test is among the first tests ordered in cancer diagnosis. CBC test results provide information about the patient’s blood cell count, including red blood cell count, hemoglobin, white blood cell count, and platelet count. For instance, patients with leukemia may present with low red blood cell and platelet counts and high white blood cell counts.

The CBC test is neither specific nor sensitive enough to confirm the presence of cancer or identify the type of cancer. Therefore, hematologists typically conduct more tests, such as those listed below, in addition to CBC.

Peripheral Blood Smear Analysis

A peripheral blood smear analysis provides more detailed information about the morphology of blood cells. This test can uncover abnormal cells, such as blasts in leukemia patients, which commonly present as larger cells with less cytoplasm than normal cells.

The peripheral blood smear analysis can also detect the presence of abnormal cells, which may result from cancer metastasizing to the blood.

Platelet Count, Morphology, and Function

Abnormal platelet morphology and function are common in cancer patients. For instance, low platelet counts may result from cancer invading the bone marrow or the chemotherapy treatments. Hematologists can also evaluate the morphology and function of platelets by conducting an assessment called a platelet aggregation assay.

Bone Marrow Examination

A bone marrow examination provides vital information about the presence and progression of cancer. In this test, a needle is placed into the bone marrow to collect a sample of the fluid and cells present in the bone marrow.

Hematologists then examine the morphology and cell count to identify any signs of cancer, such as abnormal cells or increased cell counts. The bone marrow examination provides clues for cancer diagnosis and helps determine the disease stage.


Immunophenotyping uses specific antibodies that react with antigens present on cancer cells. The test identifies the type of cancer and determines its stage. Immunophenotyping provides essential information for cancer diagnosis and for developing an individualized treatment plan.

Flow Cytometry Analysis

Flow cytometry analysis is based on the measurement of the physical characteristics of individual cells. The test is useful in identifying a specific cell population and can distinguish between normal and abnormal cells. Flow cytometry analysis can provide valuable information for leukemia and lymphoma diagnosis.

Cytogenetic Testing

Cytogenetic testing is used to detect abnormal chromosomes in cancer cells. The test can provide useful information for cancer diagnosis and help determine treatment options. Cytogenetic testing can be performed on peripheral blood, bone marrow aspiration or biopsy, or lymph node biopsy samples.

Chromosome Abnormalities Cancer Types
Philadelphia chromosome Chronic myeloid leukemia
T(9;22)(q34;q11.2) Acute lymphoblastic leukemia
T(8;21)(q22;q22) Acute myeloid leukemia

Cytogenetic testing helps hematologists detect cancer and provides insights into treatment options and outcomes.
