The alkaline phosphatase isoenzymes in 105 patients with stage D carcinoma of the prostate who entered the National Prostatic Cancer Study were analyzed and these values were correlated to clinical response. Only patients with at least 3 measurements of alkaline phosphatase were evaluated. In 91% of patients with metastatic bone disease, bone alkaline phosphatase was elevated. Those patients with higher pre-treatment levels of alkaline phosphatase generally showed a poorer response to therapy. The results of alkaline phosphatase isoenzyme estimation indicate that these biological markers may be used in the evaluation of patients with metastatic prostatic cancer to predict and monitor their response to chemotherapy. The evaluation of bone and liver alkaline phosphatase isoenzymes in earlier stages also may be valuable.

The purpose of this work was to study the time sequence and the patterns of the multistep spread of metastases. Fifty-one patients with stage D carcinoma of the prostate, previously treated for their primary tumor by surgery or radiotherapy combined with hormonal manipulation and for metastases by hormones and chemotherapy, were included in the study. The metastatic dissemination, characterized primarily by the appearance of bone metastases, could follow two distinct patterns: The first, characterized by sequential appearance of osteoblastic metastases, followed by the development of osteolytic bone lesions, and the second pattern, characterized by the simultaneous appearance of osteoblastic and osteolytic bone lesions. In cases with solely osteoblastic bone metastases, the lesions are hormone sensitive and long-lasting remissions could be obtained. The development of osteolytic bone lesions is usually accompanied by the recurrence of the primary tumor and appearance of metastases in other sites, such as the lymph nodes and lungs. Bone metastases became resistant to hormonal manipulation and with chemotherapy short remissions were obtained. The course of the terminal period is faster, with shorter survival times. The determination of serum acid and alkaline phosphatase levels seems to reflect the course of the disease during the initial period of the disease only, i.e. when bone metastases are sensitive to hormonal treatment.

The present study was undertaken to evaluate the prognostic significance of the serum levels of interleukin 6 (IL-6) in patients with prostate cancer. Serum IL-6 levels were measured in 74 patients with prostate cancer. The tumor was stage B in 23 patients, stage C in 14 patients, and stage D in 37 patients. Prognostic significance of tumor histology, performance status (PS), bone metastasis, serum prostate-specific antigen (PSA) level, serum alkaline phosphatase (ALP) level, serum lactate dehydrogenase level, serum IL-6 levels, and hemoglobin on disease-specific survival was assessed using univariate and multivariate Cox's proportional hazards model analyses. Serum IL-6 was significantly correlated with the clinical stage of prostate cancer. Univariate analysis of all patients demonstrated that an extent of disease (EOD) on bone scanning > or = 1, IL-6 > or = 7 pg/ml, PS > or = 1, PSA > 100 ng/ml, and ALP > 620 IU/liter were associated with a significantly lower survival rate than their respective counterparts. In multivariate analysis, however, the only two significant prognostic factors were EOD and IL-6. In 51 patients with stage C and stage D prostate cancer, univariate analysis showed that EOD > or = 1, IL-6 > or = 7 pg/ml, PS > or = 1, PSA > 100 ng/ml, LDH > 200 IU/liter, and ALP > 620 IU/liter were significantly related to survival, whereas multivariate analysis again demonstrated that EOD > or = 1 and IL-6 > or = 7 pg/ml were significant prognostic factors. These results indicate that the serum IL-6 level is a significant prognostic factor for prostate cancer as well as EOD.
