Therapeutic efficiency of rhenium-188-HEDP in human prostate cancer skeletal metastases.

Liepe K, Kropp J, Runge R, Kotzerke J - Br. J. Cancer (2003)

Bottom Line: Mean platelet count decreased from (286+/-75)*10(3) microl(-1) to (215+/-92)*10(3) microl(-1), and mean leucocyte count from (7.7+/-1.5)*10(3) microl(-1) to (6.0+/-1.9)*10(3) microl(-1) in the second to the fourth week after therapy.The maximal differences between the values of platelets and leucocytes before and after therapy were not statistically significant (P=0.021 and 0.094).In conclusion, (188)Re-HEDP is an effective radiopharmaceutical used in the palliative treatment of metastatic bone pain in prostate cancer and shows minimal bone marrow toxicity.

ABSTRACT
Rhenium-188-HEDP ((188)Re-HEDP) is a new and attractive radiopharmaceutical for the treatment of metastatic bone pain. As a product of (188)W/(188)Re generator, it is convenient for clinical therapeutic use with a short physical half-life of 16.9 h and a maximal beta-energy of 2.1 MeV. We investigated the effect of (188)Re-HEDP on pain relief, analgesic intake and impairment of bone marrow function in 27 patients with bone metastases induced from prostate cancer. All patients were interviewed using a standardised set of questions before, and after therapy for 12 weeks. The patients were treated with 2700-3459 MBq of (188)Re-HEDP. Blood samples were taken weekly for 12 weeks, and a blood count was performed. Patients described an improvement on the Karnofsky performance scale from 74+/-7 to 85+/-9% 12 weeks after therapy (P=0.001). The pain score showed a maximum decrease from 44+/-18 to 27+/-20% in the third to the eight week after therapy (P=0.009). Seventy-six percent of the patients described a pain relief without increase of analgesic intake. Twenty percent of the patients could discontinue their analgesics and were pain free. Mean platelet count decreased from (286+/-75)*10(3) microl(-1) to (215+/-92)*10(3) microl(-1), and mean leucocyte count from (7.7+/-1.5)*10(3) microl(-1) to (6.0+/-1.9)*10(3) microl(-1) in the second to the fourth week after therapy. The maximal differences between the values of platelets and leucocytes before and after therapy were not statistically significant (P=0.021 and 0.094). In conclusion, (188)Re-HEDP is an effective radiopharmaceutical used in the palliative treatment of metastatic bone pain in prostate cancer and shows minimal bone marrow toxicity.

Mentions: The Karnofsky performance scale increased from 74±7% before therapy to 85±9% at 12 weeks after therapy (Figure 1). This increase was statistically significant (P=0.001). Pain relief ⩽25% on the VAS at least in two consecutive weeks without increase of analgesics intake was achieved in 76% of patients (19 out of 25). Five from these 19 patients were pain free (20%). The VAS showed a decrease from 44±18 to 31±25% at the 12th week after 188Re-HEDP therapy (P=0.009) (Figure 2Figure 2
