Using circulating granulocyte-monocyte precursor colony-forming units in culture (CFUc) numbers as a probe along with standard blood count (CBC), the authors have quantitatively examined the hematopoietic toxicity of conventionally fractionated radiation therapy (RT) when combined with concurrent systemic chemotherapy or when used alone. Among 20 patients with limited stage small cell lung cancer receiving systemic chemotherapy with cyclophosphamide, CCNU, and methotrexate, the addition of involved field chest RT resulted in increased hematopoietic toxicity as judged by increased need for platelet transfusion (P less than 0.05) and decreased frequency of measurable CFUc (P less than 0.04). Among 22 patients receiving regional radiotherapy alone consistent hematopoietic toxicity was also observed. This toxicity, although generally of only mild to moderate clinical significance, was detected earlier and to a greater degree in patients who required radiation to larger treatment volumes, who had significant amounts of bone marrow in the port, and who had a high percentage of cardiac output flowing through the port. These data suggest that the hematopoietic toxicity of regional radiotherapy may be additive to that of concurrent systemic chemotherapy and may occur more promptly and to a greater degree when treatment volumes are larger or incorporate increased amounts of marrow volume or cardiac output.
