Activity and side-effects of clodronate (Ostac), an inhibitor of osteoclastic bone resorption, were recorded in an open prospective uncontrolled study on 35 patients with metastatic prostatic cancer. All patients had progressive symptomatic bone metastases despite prior hormone therapy. Clodronate was initially administered i.v. for 8 days with 300 mg/day. This was followed by a daily oral administration of 1600 mg. The analgesic effect was evaluated by using a visual analogue scale and by recording the daily consumption of analgesic drugs. Karnofsky index and routine blood examinations, including PSA, were assessed. Repeated bone scans and radiological evaluations were performed. An improvement in pain was observed in 71% of the patients. The mean duration of improvement was 4 weeks. Average survival time was 12 weeks. There were no side-effects after i.v. administration. Slight gastrointestinal discomfort was observed in 3 patients after oral administration. No effect was observed on the extent or biology of the metastases. Clodronate is an effective drug for palliative treatment of symptomatic bone metastases of prostatic carcinoma. It causes fewer and less pronounced side effects than other palliative drug therapies.

Patients with newly diagnosed prostatic cancer should be investigated with regard to the presence or absence of distant metastases by: (1) Clinical history especially of weight loss, recent pain, or analgesics intake. (2) Physical examination, looking especially for hepatic enlargement, peripheral lymph nodes, local bone tenderness. (3) Performance status. (4) Hemoglobin, creatinine, PSA and/or PAP, alkaline phosphatases, liver tests, testosterone. (5) Bone scan with X-ray of doubtful hot spots. (6) Chest X-ray. (7) Ultrasound scans (liver, kidney, lymph nodes) or CT scan may be indicated if abnormal blood parameters or in specific situations. (8) Other investigations are only indicated in special circumstances. Follow-up should include: (1), (2), (3), (4) every 3 months. For patients in clinical trials, depending on the end point, bone scan should be repeated every 6 months or possibly depending on the prognostic group (good: every 12 months; bad: 3 to 6 months). For routine clinical management, it could be repeated only when markers (PAP, PSA, alkaline phosphatase) show significant (25-50%) increase and provided the result will influence treatment. Other investigations should only be repeated or performed if abnormal at the start of if clinical data require them.

Two cases of ectopic prostatic tissue or adenomatous polyps with prostatic type epithelium in the prostatic urethra were reported. They were 30-and 33-year-old males suffering from gross-hematuria and from urethral pain on urination with terminal gross-hematuria. Endoscopic examination revealed papillary lesions from the dilated orifice of the prostatic utricle. Biopsied pathology demonstrated a tissue similar to that of the prostatic gland. PSA (prostatic specific antigen) stain using immunohistochemical methods was positive. Histogenesis and the importance of this lesion particularly as a cause of hematuria in the young male adult were discussed.

A 58-year-old man was admitted to our hospital with the complaint of pollakisuria and micturitional pain. The urine cytology showed malignant cells suggesting the urothelial cancer, but various examinations could not reveal the malignant lesion. The prostate was also normal by the digital examination, endoscopy, roentgenography, ultrasonography and serum markers, and the transperineal prostate biopsy showed no malignancy. Three years after the first admission the prostate showed slight hardness and the transperineal biopsy suggested adenocarcinoma of the prostate. Hormonal therapy was then started and the prostate showed no remarkable change until about two years later, when rapid progression of the prostatic tumor was recognized. The transperineal biopsy of the prostate revealed the transitional cell carcinoma with negative staining of Alcian-Blue, PAS and PSA (prostate specific antigen). The epithelia of the bladder and posterior urethra were normal. The radical cystoprostatectomy was done and the histological diagnosis was the pure type of primary transitional cell carcinoma of the prostate. The literatures were reviewed and the clinical differentiation between transitional cell carcinoma and adenocarcinoma of the prostate was discussed.

Prognostic factors were evaluated in advanced loco-regional (M0) or distant metastatic (M1) prostatic carcinoma treated with total androgen blockade (flutamide with either orchiectomy of LHRH-analogues), in 546 patients from a Belgian multicentric study. After a mean follow-up of 16.5 months (maximum 37 months) 113 (21%) patients had progressed (90 were patients with M1 disease (31%)). The estimated median progression-free survival exceeded 37.5 months. The results of a univariate analysis show that the following parameters are important prognostic factors with respect to progression-free survival in these patients: M stage, G grade, ECOG performance status, weight loss, concomitant disease, pain, dysuria and haemoglobin (Lee-Desu test, p < or = 0.01). From a multivariate analysis (Cox regression) the following prognostic factors were indicative of a decrease in progression-free survival: M1 stage, high initial G grade, ECOG performance status > I, high serum PSA, presence of concomitant disease, presence of pain and absence of dysuria. Age did not appear to be a statistically significant prognostic factor.

A 58-year-old male complaining of pollakisuria, miction pain and back pain visited us Dec. 26, 1979. Rectal examination revealed the prostate enlarged by 5 digital width, stony hard and irregular. Transrectal needle biopsy revealed moderately differentiated adenocarcinoma of the prostate. Bladder neck invasion, pelvic and mediastinal lymph node metastases and multiple bone metastases were found. The case was diagnosed with prostatic adenocarcinoma T3N2M1 (OSS, LYM) stage D2. Three courses of chemotherapy using ifosfamide applied from Feb. 2, 1980 showed no marked effect except for partial pain relief. Hormonal treatment with diethylstilbestrol diphosphate was started from May 28 and arterial infusion chemotherapy using CDDP and 5-FU was performed 2 months later, resulting in size reduction of the prostate and pelvic lymph node metastases and disappearance of mediastinal lymph node metastases. Needle biopsy of the prostate was negative for cancer cells. After 8 months, Tegafur was started, and 12 months later radiotherapy was added to the prostate and pelvic lymph nodes. The abnormal accumulation in bone scan began to decrease after 14 months and achieved complete remission 28 months after the initial therapy. We discontinued the hormonal therapy 31 months later because of his complaint of chest discomfort and palpitation. At the present time, 14 years after the initial therapy, the prostate was 35 x 29 x 19 mm in size on transrectal ultrasonography with undetectable serum PSA level and no tumor cells but only mass fibrosis has been seen by pathological examinations. We considered this patient to be with no evidence of disease.

Laparoscopic pelvic lymphadenectomy has been proposed for staging of prostate cancer and it might be used, in selected cases, also in bladder cancer. On a total of 31 laparoscopic lymphadenectomies (LPND), 18 for prostate cancer and 13 for bladder cancer, we found positive nodes in 8 cases (26.1%), 4 in prostate and 4 in bladder cancer group. We had no intraoperative complications and negligible postoperative complications (in 10% of cases shoulder-tip pain and in 24% subcutaneous emphysema); all these spontaneously disappeared after 24-36 hours. Patients with negative nodes underwent radical surgery except two prostate cancer patients who underwent radiotherapy, and patients with positive nodes underwent hormonal therapy (for prostate cancer) or chemoradiotherapy protocol (for bladder cancer). In conclusion, laparoscopic lymphadenectomy proved to be a feasible and safe method for staging urological malignancies, being less invasive, with shorter hospitalization and postoperative convalescence than open lymphadenectomy. It should be mainly indicated in high risk prostate cancer patients (elevated PSA and/or Gleason score). In bladder cancer patients, it could be proposed in bladder sparing investigational protocols, as the percentage of pelvic nodes metastases in T2/T3 bladder cancer is sufficiently high to justify an additional staging procedure.

Androgen deprivation displays the mean therapy of advanced stage prostatic cancer, independently of palliative radiotherapy. The evolution to hormone-resistance status leads to a fatal tumor progression. High-dose fosfestrol (diethylstilbestrol diphosphate) has been suggested to circumvent hormone-resistance and to induce a direct cytotoxic effect. Sixteen patients with hormone-resistant prostate cancer were treated by continuous infusion of high-dose fosfestrol according to two schedules: 10 patients were included in a phase I trial of a daily escalating dose from 1.5 g/d to 4.5 g/d for 7 to 10 days. Six other patients were uniformly treated by 4 g/d for 3.5 h for 5 days. Between each course, patients received orally 300 mg/d fosfestrol and 200 mg/d salicylic acid. The mean age was 65 years (range 51-75). Mean number of courses was two (extremes 1-7). Toxicities: reversible weight gain was observed in five patients. One patient presented a pulmonary edema which was resolved immediately after diuretics. One patient and 9 patients respectively experienced grade III and II (OMS) nausea and vomiting. Transient perineal pruritus occurred in 5 patients. Responses: 15 patients were evaluable (one early death occurred on day 3 from tumor progression complicated by an intravascular coagulation disease). There were four objective stabilizations (NPCP criteria) lasting 2 m, 2 m, 5 m and 10 m respectively. Subjective improvement of pain was observed in five other patients. There was more than 50% reduction of PSA in eight patients. High-dose fosfestrol seems to have some objective activity with moderate toxicity and warrants further investigation.

To investigate the efficacy and safety of bicalutamide (Casodex) with its clinically recommended dose, the randomized early phase II study was performed in 124 patients with prostatic cancer (stage C, D). The patients were given 50, 80 or 100 mg of bicalutamide orally once a day in fixed doses for 12 weeks; 122 patients were eligible for evaluation. The overall response rate was 50.0% (20/40), 61.0% (25/41) and 53.7% (22/41) in the 50 mg, 80 mg and 100 mg groups, respectively. The response rate in prostate lesion, bone and lymph node metastases was slightly higher in the 80 mg group than in the 50 mg and 100 mg groups. The proportion of patients showing a response with regard to serum PSA (CR and PR) was 84.2, 92.7 and 97.6% in the 50, 80 and 100 mg groups, respectively. The incidence of adverse reactions was 65.0, 61.0 and 61.0% in the 50, 80 and 100 mg groups, respectively, and there was no significant difference in overall safety rating in the three groups. Frequent adverse reactions were gynecomastia and breast pain. Only one patient in the 80 mg group was withdrawn due to shortness of breath. Serum concentrations of LH, testosterone and estradiol increased significantly after treatment. Bicalutamide was concluded to be effective and well tolerated in patients with prostatic cancer, and its recommended dose was 80 mg once daily.

The class I IgG receptor (Fc gamma RI or CD64 receptor), which is present on key cytotoxic effector cells, has been shown to initiate the destruction of tumor cells in vitro and has been hypothesized to play a role in the destruction of antibody-coated cells such as platelets in idiopathic thrombocytopenia purpura (ITP). This overview summarizes the clinical experience with CD64-directed immunotherapy in cancer patients with the bispecific antibodies MDX-447 [humanized Fab anti-CD64 x humanized Fab anti-(epidermal growth factor receptor, EGFR)] and MDX-H210 (humanized Fab anti-DC64 x Fab anti-HER2/neu), and with the anti-CD64 monoclonal antibody (mAB) MDX-33 (H22) in the modulation of monocyte CD64 in vivo. In an ongoing phase I/II open-label trial with progressive dose escalation (1-15 mg/m2), patients with treatment refractory EGFR-positive cancers (renal cell carcinoma (RCC), head and neck, bladder, ovarian, prostate cancer and skin cancer) are treated weekly with intravenous MDX-447, with and without granulocyte-colony-stimulating factor (G-CSF). MDX-447 has been found to be immunologically active at all doses, binding to circulating monocytes and neutrophils (when given with G-CSF), causing monocytopenia and stimulating increases in circulating plasma cytokines. MDX-447 is well tolerated, the primary toxicities being fever, chills, blood pressure lability, and pain/ myalgias. Of 36 patients evaluable for response, 9 have experienced stable disease of 3-6 month's duration. The optimal dose and the maximal tolerated dose (MTD) have yet to be defined; dose escalation continues to define better the dose, toxicity, and the potential therapeutic role of this bispecific antibody. Three MDX-H210 phase II trials are currently in progress, all using the intravenous dose of 15 mg/m2 given with granulocyte/macrophage (GM-CSF). These consist of one trial each in the treatment of RCC patients, patients with prostate cancer, and colorectal cancer patients, all of whom have failed standard therapy. At the time of writing, 11 patients have been treated in these phase II trials. Four patients have demonstrated antitumor effects. Patients demonstrating responses include 2 with RCC and 2 with prostate cancer. One RCC patient has had a 54% reduction in size of a hepatic metastatic lesion and the other has had a 49% decrease in the size of a lung metastasis with simultaneous clearing of other non-measurable lung lesions. Regarding the two patients with prostate cancer, one has had a 90% reduction in serum prostate-specific antigen (PSA; 118-11 ng/ml), which has persisted for several months; the other patient with prostate has had a 70% reduction of serum PSA (872 ng/ml to 208 ng/ml) within the first month of treatment. Both patients have also demonstrated symptomatic improvement. In a completed phase I and in ongoing phase I/II clinical trials, patients with treatment-refractory HER2/neu positive cancers (breast, ovarian, colorectal, prostate) have been treated with MDX-H210, which has been given alone and in conjunction with G-CSF, GM-CSF, and interferon gamma (IFN gamma). These trials have been open-label, progressive dose-escalation (0.35-135 mg/m2) studies in which single, and more often, multiple weekly doses have been administered. MDX-H210 has been well tolerated, with untoward effects being primarily mild-to-moderate flu-like symptoms. The MTD has not yet been defined. MDX-H210 is immunologically active, binding to circulating monocytes, causing monocytopenia, as well as stimulating increases in plasma cytokine levels. Furthermore, some patients have evidence of active antitumor immunity following treatment with MDX-210. Antitumor effects have been seen in response to MDX-H210 administration; these include 1 partial, 2 minor, and 1 mixed tumor response; 15 protocol-defined stable disease responses have occurred.
