Lymphoma

Answer Explanation:

The correct answer is “High-grade non-Hodgkin’s lymphoma has a better prognosis than low-grade”. This statement is incorrect, as low-grade non-Hodgkin’s lymphomas typically have a better prognosis than high-grade non-Hodgkin’s lymphomas.

• High-grade non-Hodgkin’s lymphomas are more aggressive and progress rapidly, but they may respond well to intensive treatment.
• Low-grade non-Hodgkin’s lymphomas grow slowly and can often be controlled with treatment, but they are difficult to cure completely.

The other options are also incorrect:

• Hodgkin’s lymphoma generally has a better prognosis than non-Hodgkin’s lymphoma.
• The staging of Hodgkin’s lymphoma does take symptoms into account.
• Reed–Sternberg cells are characteristic of Hodgkin’s lymphoma, not non-Hodgkin’s lymphoma.
• Burkitt’s lymphoma is associated with Epstein-Barr virus, not herpes simplex virus.

Overview of Lymphomas:

Lymphomas are a group of blood cancers that develop in the lymphatic system. They are generally divided into two main types: Hodgkin’s lymphoma and non-Hodgkin’s lymphoma.

Hodgkin’s Lymphoma:

• It is characterized by the presence of Reed–Sternberg cells.
• Staging takes into account the extent of the disease and the presence of symptoms.
• Generally has a better prognosis than non-Hodgkin’s lymphoma.

Non-Hodgkin’s Lymphoma:

• It does not contain Reed–Sternberg cells.
• It is further divided into high-grade (aggressive) and low-grade (indolent) types.
• Low-grade non-Hodgkin’s lymphomas typically have a better prognosis than high-grade non-Hodgkin’s lymphomas.
• Some types, such as Burkitt’s lymphoma, are associated with specific viruses (in this case, Epstein-Barr virus).
