Hodgkin's Disease - Staging and Treatment Guidelines

Indicators for Aggressive Treatments. Certain factors are indicators of a more serious case at any stage and the need for aggressive treatment:

The malignancy is "bulky" (a large mass)
Blood tests show high levels of erythrocyte sedimentation rates
Multiple tumors in the spleen
Greater involvement in the abdomen

So, for example, even if patients have stage II disease, if any such factors are present then the patients may be treated as if they had advanced Hodgkin's disease.

Cell Types. The cell type of Hodgkin's disease may also influence treatment. For example, those with mixed cellularity type might require more aggressive therapy in certain cases than those with a slower-growing form, such as lymphocyte-predominant Hodgkin's disease (LPHD). In fact, some studies are suggesting LPHD is the mildest form of Hodgkin's disease and that patients with LPHD are more likely to die of treatment-related disease than from Hodgkin's itself. Some experts, then, are investigating the role of limiting radiation doses in such patients, although the most optimal approach is not yet known.

Other Prognostic Risk Factors. The International Prognostic Factors Project on Advanced Hodgkin?s Disease has developed seven factors that help determine which patients with advanced Hodgkin's disease would benefit from more or less aggressive chemotherapy. They are also useful to help determine success in patients with relapsed or persistent HD who are undergoing stem cell transplantation. The score is determined by the number of yes answers to the following questions. The more yes answers the more likely the patient needs to be treated aggressively:

Is the patient male?
Is the patient older than 45?
Does the patient have stage IV disease?
Does the patient have blood tests showing lower than normal albumin levels? (Albumin is a protein found throughout the body.)
Does the patients have abnormally low hemoglobin levels? (Hemoglobin is the oxygen-carrying compound in red blood cells, so low levels suggest anemia.)
Does the patient have an abnormally high white blood cell count (15,000 or more)?
Does the patient have abnormally low levels of lymphocytes?

Preparing for Side Effects Before Treatment

To avoid putting patients through unnecessary treatments that may actually be as or even more lethal than the disease itself over time, doctors are attempting to identify more specifically those patients who would or would not benefit from aggressive therapy.

Preventing Infection. Both the disease and some of the treatments suppress the immune system, increasing the risk for infections. Widespread, life-threatening infection is a particular danger if the spleen has been removed and both radiation and chemotherapy are administered. A week before any treatment, patients are often vaccinated against three bacteria: pneumococcus, meningococci, and Haemophilus influenza.
