Mucinous adenocarcinoma of the prostate gland is one of the least common morphologic variants of prostatic carcinoma. A lack of precision in the definition of these mucinous neoplasms has resulted in reports which have overstated the incidence of this lesion. Of approximately 1,600 carcinomas of the prostate gland seen at Memorial Hospital from 1963 to 1983, excluding cases with only needle biopsy material, six mucinous prostatic adenocarcinomas were identified. Mucinous prostatic carcinomas were diagnosed when at least 25% of the resected tumor contained lakes of extracellular mucin, and an extraprostatic tumor site was ruled out. In five of the six cases, a cribriform pattern predominated in the mucinous areas. All of the mucinous prostatic tumors had prostate-specific
acid phosphatase
(PSAP) and prostate-specific antigen (PSA) immunoreactivity. Our experience and our review of the literature indicate that these tumors do not respond well to hormonal therapy. Contrary to prevalent opinion, they have an aggressive biologic behavior and, like nonmucinous prostate carcinomas, have a propensity to develop
bone metastases
and increased serum
acid phosphatase
levels with advanced disease.

We identified 26 cases of metastatic prostatic carcinoma in supradiaphragmatic lymph nodes from 1972-1987. All involved nodes (15 supraclavicular, eight cervical, two axillary, and one mediastinal) were taken from the left side. Of those cases with available data, serum
acid phosphatase
was normal in five of 21 (24%). Seven of 20 (35%) had no evidence of
bone metastases
. Rectal examination was normal in eight of 19 cases (42%). While seven cases had a history of prostate cancer, the rest presented with enlarged nodes alone or with simultaneous urinary obstructive symptoms. Eighteen patients died following node biopsy (mean 19.8 months, range 1-46 months). Twenty-two of 26 metastases were high grade and often were not histologically suggestive of prostate carcinoma. In general, immunohistochemical staining for prostate-specific
acid phosphatase
(PSAP) was more intense than for prostate-specific antigen (PSA), in contrast to several other reports using these antisera. Metastatic prostate carcinoma should be ruled out by using immunoperoxidase for PSA and PSAP in all men over 45 presenting with carcinoma of unknown primary origin in left-sided supradiaphragmatic lymph nodes, even in the absence of bony disease, elevated serum
acid phosphatase
(SAP), abnormal rectal examination, and a histologic picture suggesting prostate carcinoma.

Bone alkaline phosphatase (B-ALP) and tartrate resistant
acid phosphatase
(TR-ACP) are markers of osteoblastic and osteoclastic activities respectively. During a period of up to two years, these isoenzymes have been assayed in the sera of 191 breast cancer patients; 80 had
bone metastases
(BM). In BM bearing patients, B-ALP activity was 261 IU/l and 63 IU/l for patients without BM; TR-ACP was respectively 6.6 and 3.3 IU/l. Specificity and sensitivity were calculated according to several criteria. These isoenzyme serum levels were well correlated with those of two breast cancer markers (CEA and CA15.3) and radiograph.

Assessment of response of skeletal metastases to systemic therapy is currently dependent on radiological evidence of bone healing. We have performed a prospective study of additional response criteria in patients with progressive
bone metastases
from breast cancer. Changes in these potential markers of response were correlated with the radiological response and the time to treatment failure (TTF). Successful systemic therapy typically led to a transient increase in osteoblast activity ('flare'), a reduction in osteoclast activity and symptomatic improvement. After 1 month a greater than 10% rise in serum osteocalcin (BGP) and alkaline phosphatase bone isoenzyme (ALP-BI) and a greater than 10% fall in urinary calcium excretion were seen in 14/16 patients with radiographic evidence of bone healing (UICC partial responders). In comparison similar biochemical changes at 1 month were seen in only 4/20 patients with progressive disease (P less than 0.001). The predictive value and diagnostic efficiency (DE) of changes at 1 month in biochemical measurements and symptom score has been calculated. The combination of a greater than 10% rise in ALPBI and BGP and a greater than 10% fall in urinary calcium excretion had a DE of 89% for discriminating response from progression, 88% for response from non-response (progressing + no change patients), and 76% for TTF of greater than 6 months from TTF of less than 6 months. Serum calcium, tartrate resistant
acid phosphatase
(TRP), urinary hydroxyproline excretion and bone scan changes were unhelpful in discriminating between patient groups. Independent confirmation is needed, but our results suggest there are reliable alternatives to plain radiography in the early assessment of response of
bone metastases
to treatment.

Fifty-four subjects were studied: 36 advanced prostatic adenocarcinoma patients in stage D and 18 normal age-matched male controls. Serum alkaline phosphatase, serum
acid phosphatase
, plasma osteocalcin, 24-h urinary hydroxyproline excretion, and 24-h whole-body retention of [99mTc]-methylene diphosphonate were measured in all subjects before and 3, 6, and 9 weeks after the start of treatment. Skeletal metastases were identified by radiography and/or [99mTc]-methylene diphosphonate bone scan. The results confirm that
acid phosphatase
is a significant marker in prostatic cancer; serum alkaline phosphatase may be useful in the evaluation and monitoring of
bone metastases
but it is not always specific; urinary excretion of hydroxyproline is an index of osteoclastic activity; serum osteocalcin may be considered more specific in the evaluation and monitoring of osteoblastic
bone metastases
in prostatic cancer.

Aminoglutethimide (AG) and hydrocortisone (HC) were given to 20 patients with advanced prostatic cancer resistant to conventional hormonal therapy. Most patients had painful
bone metastases
and were heavily pretreated. 12 of 16 patients required narcotic analgetics. 8 of 20 were bedridden. AG + HC produced relief of bone pain in 12 patients (75%) and only 4 required narcotics after treatment. The performance status improved in 8 of 20 patients (40%). However, the number of
bone metastases
seen in bone scans decreased in only 4 patients (22%). The level of serum alkaline phosphatase decreased in 11 of 18 patients and that of
acid phosphatase
in 8 of 16 patients. The reduction of bone pain lasted approximately 4 months (range 1-15 months). The median lifespan between the start of AG treatment and death was 8 months (range 2-22 months). There was no difference in survival between responders and nonresponders. 3 patients had skin rash, 1 lethargy and 1 thrombocytopenia.

Findings of bone scintigraphy with 99mTc-MDP were compared with bone radiography and biochemical data including total
acid phosphatase
(T. ACP), prostatic acid phosphatase (P. ACP), and alkaline phosphatase (ALP) in 35 patients with histologically proven prostatic cancer.
Bone metastases
were diagnosed in 20 of 35 cases (57%) by scintigraphy. The common sites of metastases were the pelvic bones, ribs, lumbar and thoracic vertebrae. In vertebrae, metastases were mainly distributed in the lower level. The most frequent radiographic change due to metastases was the osteoblastic type. On follow-up studies, there was a relatively good agreement in the results of bone scintigraphy and radiography. However, there was a good number of cases showing discrepancy between either scintigraphy or radiography and laboratory data. Bone scintigraphy seems to be the most contributory in monitoring
bone metastases
from prostatic cancer.

Ten patients with disseminated
bone metastases
, nine from prostatic and one from renal cell carcinoma, were treated with intravenous strontium-89. Half the patients experienced significant improvement in pain control and increased general well-being for an average of 14 weeks. Sequential radiophosphate bone scanning showed decreased activity in lesions present at the time of therapy, with subsequent remineralization of the metastases on radiographs. Some patients showed simultaneous reduction in alkaline and
acid phosphatase
levels. These objective findings prove a physiologic basis for the clinical improvement. Treatments, however, did not prevent progression at initially uninvolved sites, particularly in the extremities.

One hundred and twenty-seven patients with locally advanced prostatic cancer were evaluated for the presence and progress of
bone metastases
before and during hormonal therapy, by serial radionuclide imaging and frequent measurement of plasma acid (tartrate-labile) and alkaline phosphatase. For comparison, serial changes in imaging and phosphatases were classified in each patient into one of six groups. Of 71 patients with negative imaging before treatment, 82% had normal alkaline phosphatase levels and 83% had normal
acid phosphatase
levels. Of 56 patients with
bone metastases
at presentation, false negative alkaline and
acid phosphatase
levels were noted in 18% and 36% respectively, though a few patients eventually developed abnormal levels. Serial plasma biochemistry and particularly alkaline phosphatase showed a response to treatment which was not always obvious on imaging. An assessment of the hepatic component of alkaline phosphatase by reference to plasma gamma glutamyl transpeptidase and isoenzyme electrophoresis was helpful in the evaluation of a false positive result but unnecessary where imaging was positive and phosphatase elevated. It is concluded that serial alkaline phosphatase estimation is essential in the follow-up of patients with prostatic cancer and
bone metastases
, and probably renders serial imaging studies superfluous once the presence of skeletal metastases has been proven. By comparison,
acid phosphatase
is a much less effective marker.

Measurements of human prostate-specific
acid phosphatase
by radioimmunoassay in peripheral and bone marrow sera were compared. We studied 20 patients with benign prostatic hyperplasia, 27 with untreated prostatic cancer without
bone metastases
and 11 with metastases, in addition to 7 with cancer treated by hormonal therapy. The prostate-specific
acid phosphatase
concentrations in peripheral and bone marrow serum samples were equal and did not exceed the upper limit of our health-associated reference interval, 2.8 microgram. per 1. (mean plus 2 standard deviations) in patients with prostatic hyperplasia. Of 27 prostatic cancer patients without
bone metastases
the concentration of prostate-specific
acid phosphatase
was elevated in the peripheral sera of 20 and in the bone marrow sera of 21, and 21 had an extracapsular tumor (stage T3 to T4). Prostate-specific
acid phosphatase
concentrations were elevated in peripheral and bone marrow serum specimens of all 11 patients with metastases and bone marrow cytology studies were positive in 2. There was no difference in prostate-specific
acid phosphatase
concentrations in peripheral and bone marrow serum specimens from prostatic cancer patients undergoing hormonal treatment. We conclude that the use of bone marrow serum for the measurement of radioimmunoassayable prostate-specific
acid phosphatase
in prostatic cancer patients does not provide any further information in regard to the detection of prostatic cancer compared to the use of peripheral serum specimens. Falsely positive findings in bone marrow specimens were not observed with the method used.
