放射性核素89Sr治疗骨转移癌的新进展

乳腺癌、前列腺癌和肺癌骨转移最常见的症状是骨疼痛。在广泛性骨转移癌出现严重骨疼痛时，那些通常使用的治疗手段即止痛药物、激素、化疗和外照射治疗都不够理想，且均可出现严重副作用或治疗失败。锶放射性同位素（^89Sr）治疗骨转移癌是一种新的治疗方法，也是一种安全有效的方法，较传统治疗方式而言，更能靶向定位于所有受累部位，包括骨扫描及X线片或CT，MRI难以发现的隐匿转移癌灶，选择性病灶摄取使正常组织仅受有限的辐射剂量而治疗效率增高，副作用较小。^89Sr治疗骨转移癌的总有效率大于80％，其对血细胞的抑制作用轻微且是一过性的，短期内能得到恢复。^89Sr加用外放疗或者化疗药物联合治疗，能够显著减轻骨疼痛、降低治疗的副作用，并可抑制病骨病灶继续发展而延长患者的生存期。     

Usefulness of strontium-89 for bone pain palliation in metastatic breast cancer patients

Most studies of prostate cancer have shown that strontium-89 chloride (89Sr) is effective in the palliation of metastatic bone pain, refractory to conventional analgesia. The aim of this study was to evaluate the usefulness of 89Sr for bone pain palliation in breast cancer patients. Forty women were treated with 148 MBq of 89Sr. Six patients were retreated, receiving two or more doses. The Karnofsky performance status was assessed and pain and analgesia were scored on scales of 9 and 5 points, respectively. The efficacy of 89Sr was evaluated at 3 months of treatment. The response was good in 60% of the patients and partial in 32%; there was no response in the remaining 8% (pre-treatment Karnofsky < or = 60). The duration of the response was 120+/-143 days. In the patients retreated, the response was good in 83% and partial in 17%, without significant differences compared with the first dose, but the pre-treatment Karnofsky and the duration of the efficacy were lower (P < 0.05). A transient and slight decrease of leukocyte and platelet counts after the first month of treatment with 59Sr was observed. In conclusion, breast cancer patients with metastatic bone pain can benefit from therapy with 89Sr. If necessary, the treatment may be repeated safely and with the same efficacy as is achieved after the first dose. A low functional performance status could be a cause of the lower effectiveness of 89Sr.

Strontium-89 for palliation of pain from bone metastases in patients with prostate and breast cancer

We have used strontium-89 chloride (⁸⁹Sr) for the palliative treatment of metastatic bone pain. Seventy-six patients (50 males with prostate carcinoma and 26 females with breast cancer) were treated with 148 MBq of ⁸⁹Sr. Sixteen patients were retreated, receiving two or three doses; the total number of injected doses was consequently 95. The Karnofsky performance status was assessed and pain and analgesia were scored on scales of 9 and 5 points, respectively. The efficacy of ⁸⁹Sr was evaluated at 3 months of treament. Three levels of response were considered: good – when there was an increase in the Karnofsky status and a decrease in the pain score (equal to or higher than 4) or analgesic score (equal to or higher than 1); partial – when there was an increase in the Karnofsky status and a decrease in the pain score (2 or 3 points) without significant changes in the analgesic score; no response – if no variation or deterioration in these parameters was observed. In prostate cancer patients, the response was good in 64% of cases and partial in 25%, and there was no response in the remaining 11%. In breast cancer patients, the response was good in 62% of cases and partial in 31%, and there was no response in the remaining 8%. Duration of the response ranged from 3 to 12 months (mean 6 months). In the patients who were retreated the effectiveness was as good as after the first dose of ⁸⁹Sr. A decrease in the initial leucocyte and platelet counts was observed after the 1st month of treatment, with a gradual partial to complete recovery within 6 months. It is concluded that ⁸⁹Sr is an effective agent in palliative therapy for metastatic bone pain in patients with prostate or breast carcinoma. If required, retreatment can be administered safely and with the same efficacy as is achieved by the first dose. Received 13 March and in revised form 6 June 1997     

A comparative study of 188Re-HEDP, 186Re-HEDP, 153Sm-EDTMP and 89Sr in the treatment of painful skeletal metastases

AIM: The surface bone-seeking radiopharmaceuticals 188Re-HEDP, 186Re-HEDP and 153Sm-EDTMP, and the volume seeker 89Sr were investigated to determine the efficacy and toxicity in pain palliation of bone metastases. METHOD: The effect of treatment with 188Re-HEDP, 186Re-HEDP, 153Sm-EDTMP and 89Sr on pain symptoms, quality of life, and bone marrow function were studied. In total, 79 patients (18 with breast cancer and 61 with prostate cancer) were treated (31 patients with 188Re-HEDP, 15 patients each with 186Re-HEDP and 153Sm-EDTMP, and 18 patients with 89Sr). All patients were interviewed using standardized sets of questions before and after therapy weekly for 12 weeks. Blood counts were taken weekly for 6 weeks and after 12 weeks. RESULTS: In total, 73% of patients reported pain relief (77% after 188Re-HEDP, 67% after 186Re-HEDP 73% after 153Sm-EDTMP, and 72% after 89Sr). Fifteen percent of patients could discontinue their analgesics and were pain-free. Pain showed a decrease from 3.6+/-1.7 to a maximum of 2.2+/-1.8 at visual analogue scale in 10 steps (P<0.01). Patients described an improvement on the Karnofsky performance scale from 70+/-10% to 78+/-14% 12 weeks after treatment (P=0.15). There were eight patients with a thrombocytopenia grade I, two patients with grade II and one with grade III. The maximum nadir of platelet and leukocyte counts were observed between the 2nd to 5th week after treatment and was reversible within 12 weeks. There were no significant differences in pain palliation, Karnofsky performance status (KPS) and bone marrow toxicity between the different radionuclides (P=0.087-0.449). CONCLUSION: All radiopharmaceuticals were effective in pain palliation, without induction of severe side effects or significant differences in therapeutic efficacy or toxicity.     

Effects of low-dose cisplatin on 89Sr therapy for painful bone metastases from prostate cancer: a randomized clinical trial.

This study evaluated the effects of low-dose cisplatin plus 89Sr versus 89Sr alone in the treatment of painful bone metastases from prostate cancer, addressing both pain palliation and cytostatic effects. METHODS: Seventy patients with metastatic hormone-refractory prostate cancer were randomized into 2 groups: One group (arm A) received 148 MBq 89Sr plus 50 mg/m(2) cisplatin, and the other group (arm B) received 148 MBq 89Sr plus placebo. After treatment, the patients were followed up until death to evaluate the outcome variables: grade and duration of pain palliation, onset of new painful sites, changes in bone disease, global survival, serum prostate-specific antigen and alkaline phosphatase changes, and hematologic toxicity. RESULTS: Overall pain relief occurred in 91% of patients in arm A and 63% of patients in arm B (P < 0.01), with a median duration of 120 d in arm A and 60 d in arm B (P = 0.002). New painful sites on previously asymptomatic bone metastases appeared in 14% of patients in arm A and in 30% of patients in arm B (P = 0.18). The median survival without new painful sites was 4 mo in arm A and 2 mo in arm B (P = 0.04). Bone disease progression was observed in 27% of patients in arm A and in 64% of patients in arm B (P = 0.01). Median global survival after therapy was 9 mo in arm A and 6 mo in arm B (P = 0.30). Transient and moderate hematologic toxicity, as determined by World Health Organization criteria, was apparent in both arms without significant differences. CONCLUSION: The addition of a low dose of cisplatin enhances the effect of a standard dose of 89Sr without significant side effects, producing a significant improvement in pain palliation and a cytostatic effect on bone disease.     

89Sr versus 153Sm-EDTMP: comparison of treatment efficacy of painful bone metastases in prostate and breast carcinoma

BACKGROUND AND AIM: Painful bone metastases are most frequent in patients with advanced prostate or breast carcinoma. The aim of this study was to compare the analgesic effect of radionuclide therapy using Sr and Sm-EDTMP in patients with painful bone metastases of these tumours. MATERIAL AND METHODS: One hundred patients treated with radionuclide bone palliation therapy were analysed. The study population consisted of 60 male patients with advanced prostate carcinoma and 40 female patients with advanced breast carcinoma. Fifty patients (30 men and 20 women) were treated with Sr (150 MBq). The other 50 patients were treated with Sm-EDTMP (37 MBq x kg). The treatment efficacy was evaluated by a visual analogue scale (VAS), Karnofsky performance scale, and dosage of analgesic drugs used. RESULTS: Complete pain relief was found in 40% of women and 40% of men treated using Sm-EDTMP and in 25% of women and 33% of men treated with Sr. No analgesic effect occurred in 20% of patients. A better analgesic effect was found in cases of osteoblastic metastases compared to mixed metastases. Statistically significant reduction of pain intensity, use of analgesic drugs and improvement of performance in Karnofsky scale was found in cases of both radionuclides. CONCLUSIONS: The analgesic effects of Sr and Sm-EDTMP was similar in both prostate and breast carcinoma. However, the effect was dependent on the type of metastases; better response was observed in cases of osteoblastic metastases than in patients with mixed metastases. Severe adverse reactions after this therapy were rare.     

Strontium-89: treatment results and kinetics in patients with painful metastatic prostate and breast cancer in bone

Two hundred and two patients with bone pain from metastatic cancer were treated with 40 microCi/kg of Sr-89. Patients were followed with pain diaries, records of medication taken, sleep patterns, serial bone scans and a Karnofsky Index. One hundred and thirty-seven patients with adequate followup survived at least 3 months, including 100 with prostate and 28 with breast carcinoma. Eighty of the 100 patients with prostate cancer responded, and 25 of the 28 breast cancer patients improved. Ten patients with prostate cancer and five with breast cancer became pain free. Little hematologic depression was noted. Sr-89 kinetic studies showed that strontium taken up in osteoblastic areas remained for 100 days. The tumor-to-marrow absorbed dose ratio was 10:1.
