`HIGH DOSE KETOCONAZOLE FOR THE TREATMENT OF
`HORMONE REFRACTORY METASTATIC PROSTATE CARCINOMA:
`16 CASES AND REVIEW OF THE LITERATURE

`
`ABSTRACT
`- We treated 16 patients who had hormone refractory metastatic prostate cancer with 400 mg.
`ketoconazole orally every 8 hours. None ofthe patients had an objecfive response, although 6 (37:b
`per cent) had stable disease (2 of whom had a subjective decrease in bone pain). Thl median
`duration of stable disease was 6.8 months (range 2to 72 months) and side effects were seen in 14
`patients. Nausea, vomiting or anorexia was noted in 10 patients, rash and pruritus in 2, transient
`abnormal liver function tests in 1 and transient pulmonary infiltrates in 1.
`Nine prior studies inv^estigating the use of ketoconazole in hormone refractory metastatic prostate
`cancer were leviewed. Only 1 complete response was reported. A partial t".pon"" was noted in 14
`pe_r cent-of the patients. Most of the patients had stable or progressive disease.
`High dose ketoconazole_as a single agent appears to have li-It"d rrs. in patients who have failed
`prior systemic therapy. (J. Urol., j42: 8g-91, 19g9)
`
`since prior
`
`least 4 weeks
`radiotherapy, hormonal therapy or
`chemotherapy.
`The pre-treatment diagnostic evaluation consisted of historv
`and physical examination, complete blood count, liver function
`tests, total,and prostatic acid phosphatase, chest x_ray and
`bone scan. Subsequent evaluation inciuded history and physical
`examination, complete blood count and liver function tests
`every 3 weeks, total and prostatic acid phosphatase and chest
`x-ray (if a measurable lesion was present) every 6 weeks, and
`bone scan every 3 months (or earlier if there was increasing
`bone pain). Serum prostate specific antigen anci serum testos_
`terone were not evaluated.
`Tumor response was evaluated according to National pros-
`tatic Cancer Project criteria,rs
`
`RESULTS
`Patient characteristics and responses to therapy are noted in
`table 1. None of the 16 patients had an objeciive response
`
`Adenocarcinoma of the prostate is androgen dependent in
`the majority of cases.' Most of the circulating androgens in
`man are secreted by the testes and adrenal glands.z Conven-
`tional management of advanced prostate cancer has been ori-
`ented towards reducing circulating androgens by orchiectomy
`or estrogen therapy to attempt to induce disease remission.
`However, although 75 per cent of the patients respond to the
`aforementioned therapy, disease progression is associated with
`a 6-month survival of only 50 per cent and median over-all
`survival of 2.5 years."'' In men with hormone refractory disease,
`cytotoxic chemotherapy has been used with minor success and
`often is associated with toxicity."
`Ketoconazole is an orally administered bioad-$ectrum an-
`tifungal agent that blocks gonadal and adrenal synthesis of
`androgens,'and has a direct antitumor effect on prostatic
`cancer cells in vitro.'' Thus, high dose ketoconazole may be of
`potential value in the treatment of metastatic prostate cancer.
`Several investigators have reported good initial tumor re-
`sponses with ketoconazole in patients with untreated advanced
`prostate cancer, with few treatment-related side effects.,i't
`The poor response of hormone refractory prostate cancer to
`alternative systemic therapy and the promising results of the
`aforementioned pilot studies stimulated us to investigate the
`activity of ketoconazole in our patients with estrogen or or-
`chiectomy refractory metastatic disease.
`
`MATERIAL AND METHODS
`We studied 16 patients with estrogen or orchiectomy refrac-
`tory metastatic adenocarcinoma of the prostate. Ten patients
`had undergone orchiectomy, 4 had received diethylstilbestrol
`and 2 had received orchiectomy plus diethylstilbestrol. Keto-
`conazole (400 mg. every 8 hours orally) was given to all patients
`according to the dosage used in prior studies.6-1"
`Eligibility requirements for this study included histologically
`proved adenocarcinoma of the prostate with measurable or
`evaluable disease, life expectancy of at least 3 months, perform-
`ance status of 2 or better (Eastern Cooperative Oncology Group
`criteria),tt no prior treatment with ketoconazole, no hepatic
`dysfunction (that is total bilirubin less than 2 me./dlj and at

`3). Hepatotoxicity in these studies was rarer and usually re-
`solved quickly after stopping therapy.
`In summary, high dose ketoconazole as a single agent appears
`to have limited use in patients who have failed prior hormonal
`therapy for advanced prostate cancer. The use of this drug is
`limited further by its frequent side effects and high cost (ap-
`proximately $9 to $10 daily for 400 mg. 3 times per day).

`although 6 (3?.5 per cent) had stable disease, of whom 2 had
`subjective decrease in bone pain. The serum acid phosphatase
`was elevated in 12 patients but decreased in only 3 in response
`to ketoconazole. In the 3 patients in whom a palpable prostatic
`nodule could be evaluated no response to ketoconazole was
`noted. The median duration of stable disease was 6.8 months
`(range 2 to 12 months).
`Side effects were seen in 15 patients. Nausea, vomiting and
`anorexia were noted in 10 patients. One patient had abnormal
`Iiver function tests (for example serum glutamic oxaloacetic
`transaminase of 364 and total bilirubin 6.7) necessitating drug
`withdrawal 4 days after commencing therapy. These abnor-
`malities resolved after 1 week of treatment. Two patients had
`pruritus and an erythematous rash that resolved when the drug
`was temporarily discontinued. When these patients restarted
`therapy no further skin complications occurred. Severe dyspnea
`and pulmonary inberstitial infiltrates on chest x-ray occurred
`in 1 patient 4 days after starting treatment. These abnormali-
`ties subsided after 14 days offtherapy.
`
`DISCUSSION
`Table 2 compares prior studies with the present series.s 16
`The dose of ketoconazole used in all studies was 400 mg. every
`8 hours. In 3 of the studies the dose was reduced to 200 mg.
`every 8 hours in some patients.l0 r2 Only 1 complete response
`has been reported. Partial responses have been infrequent (14.3
`per cent over-all). In those studies in which it was noted the
`duration of response was short-lived, ranging from 3 to 13
`months.e' Ir' r3-r5 Most patients have had stable or progressive
`disease. A subjective improvement in bone pain was noted in
`some patients despite a Iack of objective response. In 4 of the
`studies a further significant decrease in serum testosterone
`concentration during ketoconazole therapy was noted.s r('r?
`Side effects have been frequent, most commonly nausea and
`vomiting @2 per cent over-all), fatigue, lethargy and rash (table
