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.

Patients with newly diagnosed prostatic cancer should be investigated with regard to the presence or absence of distant metastases by (1) Taking a history especially of weight loss and recent onset backache (2) Examining them, looking especially for hepatic enlargement or peripheral lymph nodes (3) Performance status (4) Hemoglobin, Bilirubin, Liver enzymes, Alkaline and Acid phosphatase (5) Chest Xray. (6) Bone scan with specific Xrays directed at hot spots. (7) Ultrasound scan of liver if liver function tests are abnormal. Ultrasound scan of lymph nodes and kidneys is optional. (8) Any other tests indicated in special circumstances. Follow-up, 3-monthly as a rule, should include (1) The presence of pain and analgesic requirements (2) Weight (3) Performance status (4) Hemoglobin, Alkaline phosphatase, Acid phosphatase (5) Chest Xray, three monthly if abnormal. Annually otherwise. (6) Bone scan with Xray of new hot spots, 6-monthly. If there is doubt about the presence of a new hot spot, repeat the bone scan and Xray at 3 months.

Neocarzinostatin (NCZ), a new antitumor antibiotic, was administered to 19 patients with bladder cancer, 16 patients with prostatic cancer, and 3 patients with hepatoma. All patients had objectively measurable metastatic lesions including 21 with palpable nodes or subcutaneous nodules, 10 with pulmonary nodules as demonstrated by chest x-ray, 4 with malignant hepatomegaly, and 3 with bidimensional pelvic masses as demonstrated by CT scanning. Sixty-five courses of NCZ were administered via an intravenous bolus daily for five days with dosages ranging from 1500 to 3000 U/m2. Immediate toxicity was not dose-limiting except for 1 episode of anaphylaxis and 1 of acute renal failure. Myelotoxicity was delayed, dose-dependent, noncumulative, and dose-limiting. Thrombocytopenia was prolonged or irreversible in 5 cases. The maximally tolerated dose was 2750 U/m2. One patient with NCZ-associated pulmonary fibrosis and 1 with biopsy-proven hepatitis are discussed in detail. Neocarzinostatin demonstrated minimal therapeutic activity (1 partial remission) in patients with bladder cancer. There was no response in patients with prostatic cancer or hepatoma.

We have noticed that functional disorders of the liver characterized by hepatomegaly and an increase in serum gamma-glutamyl transpeptidase develop in patients with prostatic cancer who are placed under longterm therapy with massive doses of estrogen after castration. We performed laparoscopy in six cases of prostatic cancer with hepatomegaly so that we could study the morphology of the liver. Our findings were as follows. In five, the histological features of the liver biopsies were very similar to those seen in alcoholic hepatitis. In spite of this fact, two of the five had no history of alcohol consumption. Furthermore, in one other case, liver damage resembling alcoholic hepatitis developed during abstinence. The findings in these three cases suggested that long-term, massive doses of synthetic estrogen may lead to liver injury similar to alcoholic hepatitis in nonalcoholics. The ultrastructural findings of the liver cells were also suggestive of the adverse effect of treatment. All cases were negative for hepatitis B surface antigen. Recent reports have demonstrated some nonalcoholics with histological features of the liver indicative of alcoholic hepatitis. This particular condition was termed "nonalcoholic steatohepatitis" by Ludwig et al. It is quite likely that synthetic estrogen is also responsible for "nonalcoholic steatohepatitis" when it is used in massive doses.

A 65 year old man presented with a two-month history of low back pain and fatigue and urinary symptoms over the preceding month. He was found to have had a hepatomegaly & a large nodular prostate on rectal examination. Investigations revealed a normal full blood count and renal profile, raised alkaline phosphatase and Prostate Specific Antigen (PSA), and low serum Calcium. A bone scan was performed which revealed widespread bony metastases in the axial and appendicular skeleton resulting in a 'superscan', consistent with prostatic metastases. We recommend that calcium levels be checked in all patients with prostate cancer and metastatic bone disease as this may have a bearing on their symptoms and the use of bisphosphonate therapy.

Flutamide (FLU), an oral, nonsteroidal antiandrogen drug used in the treatment of prostate cancer, is associated with idiosyncratic hepatotoxicity that sometimes causes severe liver damage, including cholestasis, jaundice, and liver necrosis. To understand the mechanism of toxicity, a combination of aryl hydrocarbon receptor (Ahr)-deficient (Ahr-/-) mice, primary hepatocytes, luciferase reporter gene assays, in silico ligand docking and ultra-performance chromatography-quadrupole time-of-flight mass spectrometry-based metabolomics was used. A significant increase of liver weights, and liver and serum bile acid levels was observed after FLU treatment, indicating hepatomegaly and disrupted bile acid homeostasis. Expression of the AhR gene battery was markedly increased in livers of wild-type mice Ahr+/+ treated with FLU, while no change was noted in Ahr-/- mice. Messenger RNAs encoded by AhR target genes were induced in primary mouse hepatocytes cultured with FLU, which confirmed the in vivo results. Ligand-docking analysis further predicted that FLU is an AhR agonist ligand which was confirmed by luciferase reporter gene assays. Multivariate data analysis showed that bile acids were responsible for the separation of vehicle- and FLU-treated Ahr+/+ mice, while there was no separation in Ahr-/- mice. Expression of mRNA encoding the bile acid transporter ABCC4 was increased and farnesoid X receptor signaling was inhibited in the livers of Ahr+/+ mice, but not in Ahr-/- mice treated with FLU, in agreement with the observed downstream metabolic alterations. These findings provide new insights into the mechanism of liver injury caused by FLU treatment involving activation of AhR and the alterations of bile acid homeostasis, which could guide clinical application.

A 69-year-old man with prostate cancer presented to the hospital with 2 weeks' history of fever, abdominal distension, and fatigue. Laboratory findings showed signs of acute liver failure, and marked elevation of lactate dehydrogenase and tumor marker levels. Abdominal CT showed hepatomegaly with multiple hypodense lesions in both lobes, suggesting metastases. FDG PET/CT scan shows hypermetabolism unusually in the liver with significantly suppressed heart and brain activity, reminiscent of an FDG hepatic superscan. The hypermetabolic lesions confirmed with Tru-Cut needle biopsy of the liver as metastasis of prostate cancer.
