The prognosis of U.S.A. patients with prostate cancer based on reports from the American College of Surgeons and Roswell Park Cancer Institute was compared with that of Japanese in Nagasaki and Gunma. There was more than a 10% difference in survival rate between the two countries. Several clinical parameters were analyzed to determine the basis for this difference. In general, stage distribution, metastatic sites, bone pain and alkaline phosphatase in the USA patients with Stage D disease were more severe than in the Japanese patients. Moreover the prostate cancer death rate in the USA was higher than that in Japan. However, only the distribution of pathological grade in the USA was better than that in Japan. From these results, it is difficult to conclude that prostate cancer in the USA is more aggressive than in Japan. The possibility of selection bias in these studies is discussed.

Pamidronate is one of several powerful bisphosphonates able to produce prolonged remissions of Paget's disease. This study examined to what extent bone scan changes parallel the clinical response and whether there is variability in the behavior of individual lesions. Twenty-five patients with pagetic bone pain for more than 2 yr were examined with bone scintigraphy before and on average 8 mo after six 30-mg infusions of pamidronate given weekly. Serum alkaline phosphatase and urinary hydroxyproline-to-creatinine ratios were measured before and 6 mo after treatment. A second course of pamidronate was given to 13 patients who had clinical or biochemical relapse. Of 136 pagetic lesions, 13 (10%) completely resolved, 90 (65%) improved and 33 (24%) remained unchanged. There was no significant difference in response between bony sites, although less active lesions were more likely to resolve completely. In conclusion pamidronate has a powerful effect on bone scan appearances in Paget's disease. Most lesions improve but complete resolution is uncommon. Less active lesions are more likely to resolve and are less likely to require further therapy.

Osteomalacia is characterized by large osteoid seams and a preserved volume of bone trabeculae. The mineralization of newly formed bone requires adequate concentrations of calcium and phosphate: the Ca.P product has been regarded as a useful, empirical diagnostic test of osteomalacia. It decreases in patients with osteomalacia mainly because they have very low plasma phosphate levels. At present total body bone mineral and total body bone density can be directly measured by whole body absorptiometry, which indicates the lowest total mineral content of the skeleton which can increase quickly after adequate treatment. The main symptoms of osteomalacia are: bone pain; muscular weakness (commonly as pelvic girdle myopathy); Looser-Milkman pseudofractures or more often a pattern of generalized demineralization at X-ray. The main biochemical parameters in osteomalacia include: defective calcium absorption with hypocalcemia and hypocalciuria; defective intestinal phosphate absorption with hypophosphatemia; there is often increased renal phosphate clearance due to hypocalcemia and secondary hyperparathyroidism; elevated alkaline phosphatase and osteocalcin levels; high bone turnover confirmed by kinetic studies carried out with radiocalcium or 99mTc-MDP. An etiological classification of the osteomalacias includes: 1) nutritional osteomalacia: a) inadequate exposure to sunlight and/or insufficient vitamin D intake; b) defective intestinal absorption of vitamin D because of malabsorption syndromes (e.g. jejuno-ileal bypass for obesity).(ABSTRACT TRUNCATED AT 250 WORDS)

rhG-CSF (recombinant human granulocyte colony stimulating factor) promotes production and release of neutrophil from bone marrow, and it enhances neutrophil function. In this study, the pharmacokinetics, effects on neutrophil and immune functions and efficacy and safety of rhG-CSF were studied in patients with end-stage renal failure (CRF). To 9 patients with CRF; 2 patients on conservative therapy and 7 patients under regular hemodialysis, 50 micrograms/m2 rhG-CSF were administered intravenously under the schedule of single or 2 week consecutive injection. In single injection study, serial changes in plasma rhG-CSF concentration and peripheral blood cell count were examined following the administration. In consecutive injection study, plasma rhG-CSF concentration, anti-rhG-CSF antibody, peripheral blood cell counts, blood chemistry and coagulation factors, and neutrophil and immune functions were examined. As the results, 1) Half life of rhG-CSF, 2.87 +/- 0.65 hr, was about 2 times longer than that in healthy subjects, and it was not affected by hemodialysis treatment. 2) Marked increase in leukocyte and neutrophil counts and mild increase in lymphocyte count were observed during single and consecutive administration of rhG-CSF. There was no significant change in other leukocyte differentiations, RBC, or platelet count. 3) Neutrophil alkaline phosphatase score increased significantly during single and consecutive administration, and other neutrophil function also improved in several patients with impaired neutrophil function. 4) Slight bone pain and increase in serum alkaline phosphatase were observed in about a half of patients during consecutive injection study. Neither antibody nor accumulation of rhG-CSF was noted.(ABSTRACT TRUNCATED AT 250 WORDS)

The independent prognostic factors affecting survival were assessed in 240 men undergoing treatment for metastatic prostate cancer as part of a randomized clinical trial comparing the gonadotropin releasing hormone analogue Zoladex (goserelin acetate implant) with castration. In a multivariate analysis, the most highly significant predictors were the presence or absence of bone pain, serum testosterone levels, serum alkaline phosphatase levels, and performance status. Patients with all four factors favorable for survival had a 2-year survival rate of 84% as compared with only 8% for patients with none of the four factors favorable for survival. No other factors were significant. A separate analysis of serum testosterone levels revealed that the higher the pretreatment serum testosterone level, the greater the survival rate. Compared with patients with serum testosterone levels less than 6.9 nmol/L, significant differences in survival were observed for patients with serum testosterone levels of 10.4 to 13.9, 13.9 to 17.3, and over 17.3 nmol/L. These results have important implications for the design and analysis of future clinical trials of hormone therapy and for counseling patients regarding the short-term prognosis of their disease.

We investigated bone mineral content and factors related to decreased bone mineral content in maintenance hemodialysis patients. Bone mineral contents, epsilon GS/D, radius-bone mineral content (R-BMC) and L3-bone mineral density (L3-BMD), were measured with a micro densitometer, a bone mineral analyzer and a dual energy quantative CT scanner, and relative bone mineral contents (% epsilon GS/D, %R-BMC and %L3-BMD) were calculated respectively. The desferrioaxmine infusion test was carried out for diagnosis of aluminium associated bone disease, and an elevated level of aluminium (delta aluminium) was observed. There was reverse correlation between epsilon GS/D and age in female hemodialysis patients. Serum bone gla protein, alkaline phosphatase and PTH-C levels were high in cases with increased epsilon GS/D and who were receiving little medication with activated Vitamin D in maintenance hemodialysis patients. A correlation was observed between delta aluminium and total medication of aluminium hydroxide-gel. Hemodialysis patients with bone pain had long term hemodialysis, high total medication of aluminium and high aluminium. Relative bone mineral contents (% epsilon GS/D, %R-BMD) were useful for estimating bone mineral content in hemodialysis patients. Hemodialysis patients were divided in four groups by PTH-C and delta aluminium levels as follow, 1) normal, 2) aluminium associated bone disease, 3) secondary hyperparathyroidism with aluminium associated bone disease, 4) secondary hyperparathyroidism. These results indicate that secondary hyperparathyroidism, and medication with aluminium may play a role in decreased bone mineral content in hemodialysis patients, and menopause may also be an important factor in female hemodialysis patients.

Fourteen patients with chronic renal failure and secondary hyperparathyroidism were treated by subtotal parathyroidectomy. Bone pain and hypercalcemia were the main indications to surgery respectively in 13 and 1 patients. Bone pain disappeared or was significantly reduced in 12/14 patients. Two patients had a persistent hyperparathyroidism. Serum alkaline phosphatase returned to normal in 12 patients and PTH in 11 of 12 patients with pretreatment high levels.

The purpose of this study was to establish the smallest dose of nasally administered salmon calcitonin (SCT) which, if given in conjunction with a previously published calcium/thiazide treatment, would be as effective as parenteral SCT in the treatment of Paget's disease of bone. Forty patients suffering from symptomatic Paget's disease were treated with 0.5 g calcium three times daily, 10 mg/day clopamide, and 400 IU nasally administered salmon calcitonin given once or twice weekly. This regimen was given for 5 months, after which all treatment was ceased for 4 months. Parenteral SCT (100 IU) was then given three times weekly for 5 months to 25 of the patients. With the oral/nasal treatment, the plasma alkaline phosphatase level (AP) decreased by 30 +/- 15 (SD)% when the SCT was given once weekly and by 39 +/- 11% (P less than 0.05) when the SCT was given twice weekly. There were similar decreases in the fasting urinary hydroxyproline:creatinine ratios. The parenteral SCT reduced the AP by 33 +/- 23%. Though reduction in bone pain was similar with both treatments, most patients preferred the oral/nasal treatment. It is concluded that the oral/nasal treatment, when the SCT is given twice weekly, has similar efficacy to parenteral SCT, and is a well tolerated, effective initial treatment for Paget's disease of bone.

Clinical interest in salmon calcitonin began in 1972 when this peptide was shown to be effective in the treatment of Paget's disease. Salmon calcitonin is more potent than porcine calcitonin, with human calcitonin intermediate in potency. Salmon calcitonin is a highly effective therapeutic agent in the treatment of Paget's disease. During chronic treatment with salmon calcitonin, alkaline phosphatase activity and urinary hydroxyproline excretion decrease on an average of 50% in patients with Paget's disease. Patients may experience a variety of clinical benefits during chronic treatment, including relief of bone pain, a reversal of neurological deficits, stabilization or improvement of hearing loss, and improvement of vascularity of bone. Radiologic healing of osteolytic lesions in particularly striking with calcitonin treatment. Paget's disease patients prefer treatment with salmon calcitonin administered by means of a nasal spray. Salmon calcitonin has an excellent safety profile and produces mild side effects in a small percentage of patients. The most common side effects associated with salmon calcitonin administration are nausea and facial flushing. It is unusual to observe severe side effects. In about 20% of patients, production of antibodies may neutralize the effects of the exogenously administered calcitonin; these patients respond to human calcitonin. At this time salmon calcitonin should still be considered a valuable therapeutic agent in the treatment of Paget's disease, particularly in patients with osteolytic lesions.

Five of 23 patients with recurrent nasopharyngeal carcinoma (NPC) were diagnosed to have bone marrow metastasis. They all had advanced local-regional disease, and were treated with neoadjuvant chemotherapy and definitive radiotherapy after the initial diagnosis. Bone marrow metastasis developed 4-24 months later. The clinical features were anemia (5 of 5), leukopenia (3 of 5), thrombocytopenia (4 of 5), sepsis (3 of 5), tenderness of the sternum (3 of 5), and fever (4 of 5). Patients frequently had elevation of serum lactic dehydrogenase (LDH), alkaline phosphatase (ALK-P), and IgG and IgA antibody titers to Epstein-Barr viral capsid antigen when bone marrow involvement was diagnosed. However, clinical manifestations and laboratory tests were not specific. It is important that three patients had normal bone scans. All five patients had a rapid downhill course; four patients died within 23 days, and the fifth 3 months after the diagnosis of bone marrow metastasis. We concluded that bone marrow was a common metastatic site in NPC patients. Bone marrow metastasis adversely affected patients' survival and required a high index of suspicion for diagnosis. We suggested that bone marrow biopsy should be considered as a routine staging procedure in NPC patients and indicated especially when patients presented with abnormal blood counts, sepsis, bone pain, or tenderness of the sternum. It may be positive in the face of a normal bone scan.
