The aim of the study was to investigate men with prostate cancer and benign prostatic hyperplasia (BPH) in comparison with men from the general population in aspects of presence and frequency of micturition problems in remembrance of prior to treatment and currently. Further, the aim was to investigate the impact of micturition problems on quality of life and the association with micturition problems, and quality of life and sense of coherence (SOC). The samples consisted of 155 men with prostate cancer, 131 with BPH, and 129 from the general population. Micturition problems were assessed with study-specific questions, modified International Prostate Symptom Score (IPSS), quality of life questionnare (QLQ C-30), and SOC questionnaires. Parametric and nonparametric statistics were applied. Most troublesome urinary problems were leakage, feelings of discomfort, and disrupted urinary function and frequency. Men with urological diagnosis had more micturition problems, fatigue, and sleeping difficulties than men from the general population, but the cancer diagnosis did not add to the problems. Role and social functioning (prostate cancer), emotional functioning (BPH), and grade of fatigue (general population) showed itself vital for overall quality of life. Thus, help in solving issues of micturition problems, fatigue, and sleeping disturbances may contribute to maintenance of role, social, and emotional aspects of life.

Prostate cancer continues to occur in over 230,000 men each year. Although the majority of these will be diagnosed in the early stages, there remains a proportion who will either be diagnosed in late stage disease or develop progressive disease. In patients with advanced disease, research has recently focused on using chemotherapy for symptom management and palliation. Given that the focus is not on cure, the effect of chemotherapy on quality of life is of utmost importance. The present article will 1) summarize the current chemotherapeutic studies that have included a quality of life component, with a particular focus on pain and fatigue, 2) discuss the issue of distress in advanced prostate cancer patients treated with chemotherapy, and 3) suggest future research directions. From the studies that have investigated quality of life, it appears that several chemotherapeutic agents reduce pain and fatigue, although the development of fatigue is often the dose-limiting factor of some agents. The assessment of overall quality of life has occurred in several studies, however, an examination into the impact of chemotherapy on functional status and interpersonal relationships has not been studied. Finally, in contrast to the numerous studies in early stage prostate cancer patients, the presence and effect of distress in chemotherapy-treated prostate patients has not been examined. As such, increased attention is needed to quality of life during phase I-III chemotherapy trials.

Thalidomide has re-emerged as a novel antineoplastic agent with immunomodulatory and antiangiogenic activities. In the early sixties, it was withdrawn from the market after its infamous association with congenital abnormalities that left about 10,000 children affected world-wide. With strict regulations and precautions, thalidomide is now approved by the FDA for the treatment of erythema nodosum leprosum. Its role in cancer therapy is promising, with clinical trials in the past 5 years showing significant activity in multiple myeloma. Several trials are ongoing in other malignancies, such as myelodysplastic syndrome, agnogenic myeloid metaplasia, renal cell carcinoma, and prostate cancer. The major toxicities of thalidomide are birth defects, sensorimotor peripheral neuropathy, somnolence, rash, fatigue, and constipation. Less common side effects include deep venous thrombosis, Stevens-Johnson syndrome, elevated liver enzymes, malaise, and peripheral edema. The incidence and severity of adverse events are related to dose and duration of therapy. Doses of the drug of 200 mg/day or less are usually well tolerated. In this review, we will discuss the incidence and management of the side effects of thalidomide and the precautions and interventions needed to minimize the toxicities of this drug.

This study assessed the prevalence, clinical characteristics and risk factors for insomnia in patients treated with radical prostatectomy for prostate cancer. A total of 327 patients completed a battery of questionnaires assessing sleep and related issues (i.e. anxiety, depression, fatigue, quality of life). Results indicated that 31.5% of the patients currently reported non-specific sleep difficulties, while 18% met specific criteria for an insomnia syndrome. In most of these latter cases (95%), the insomnia was chronic (duration of 6 months or more). Nearly half of patients with an insomnia syndrome reported that the onset of their sleep difficulties followed the cancer diagnosis. A similar proportion had no comorbid clinical levels of anxiety or depression. Risk factors for the presence of an insomnia syndrome included a younger age, a worse prognosis, and the presence of intestinal, pain, depressive, and androgen blockade-related symptoms. Thus, insomnia is a frequent problem associated with prostate cancer, that often occurs independently of anxiety and depression, but seems to be influenced by the presence of physical and psychological symptoms associated with prostate cancer and its treatment.

Is well being in the elderly be improved by hormone replacement therapy which compensate deficits accounting for generalized weakness, poor endurance, loss of muscle strength, impaired mobility and balance and decreased cognitive functions? Hormone replacement therapy of menopause has favorable effects on bone loss and decreased cognitive functions but also on several unpleasant symptoms--vasomotor instability, skin atrophy, mucosal dryness, anxiety and fatigue--but at the prize of increased incidence of cancer and cardiovascular morbidity. Decreased testosterone levels in elderly men are associated with increased fatigability, decreased muscle strength and bone mass and increased risks of accelerated atheromatosis. Testosterone substitution seems to be helpful but with side effects, particularly development of prostate cancer. Aging also affects adrenal function. The consequences of decreased DHEA production are still matter of debate. DHEA administration in elderly women seems to be associated with favorable effects on physical and psychological well being. Somatopause is characterized by a progressive decrease of growth hormone production starting as soon as the third decade. Growth hormone therapy has favorable effects on lean body mass, skin atrophy as well on body fat reduction. However, numerous side effects and the theoretical increased risk of cancer limit the use of growth hormone therapy in the elderly.

An open-label study conducted in community centers assessed the safety of zoledronic acid 4 mg intravenously over 15 minutes every 3-4 weeks as treatment of bone metastases in patients with multiple myeloma, breast cancer, or prostate cancer with and without previous bisphosphonate exposure. Adverse events (AEs), pain, and quality-of-life (QOL) scores were recorded, and serum creatinine (SCr) levels were measured before each infusion. Of 638 patients, 415 patients (65%) had received prior bisphosphonate therapy. Fatigue, nausea, and arthralgia were the most frequent AEs. Nausea was more common in bisphosphonate-naive patients. SCr levels increased notably in 6.6% of patients: 7.7% of patients who received prior bisphosphonate therapy and 4.5% of bisphosphonate-naive patients. Treatment was delayed because of SCr-level increases in 1.4% of patients with prior bisphosphonate exposure and 0.4% of bisphosphonate-naive patients. SCr-level increases and treatment delays did not correlate with duration of prior bisphosphonate therapy. There was a trend towards more treatment discontinuations in patients with prior bisphosphonate exposure compared with bisphosphonate-naive patients. Pain scores decreased from baseline; total QOL scores remained constant. The results of this study suggest that, with proper SCr-level monitoring, cancer patients with bone metastases who have previously received intravenous bisphosphonate treatment can be safely converted to zoledronic acid therapy.

Thalidomide has anti-angiogenic and immunomodulatory activity, exhibiting antitumour effects in patients with multiple myeloma and, more rarely, in several other solid tumours. We evaluated the single-agent antitumour activity and toxicity profile of thalidomide in patients with metastatic malignant melanoma, as well as its plasma pharmacokinetics and pharmacodynamic effects [vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (b-FGF) levels]. A two-stage Gehan method was used with a stopping rule after 14 consecutive non-responding patients. Thalidomide was given orally at a daily dose of 200 mg/day, which was then escalated every 2 weeks by 200 mg/day as tolerated to a maximum of 800 mg/day. Patients were evaluated every 8 weeks for response using the World Health Organization (WHO)-27 criteria. Fourteen patients were enrolled and no objective responses were observed, with one stable disease and one mixed response. The dose-limiting toxicities were constipation, dizziness and somnolence. Other toxicities were oedema, neuropathy, dry skin, dry mouth, tremor and fatigue. The plasma pharmacokinetics of thalidomide were comparable with those of previous studies in normal volunteers and in patients with advanced prostate cancer. Serum levels of b-FGF and VEGF did not change significantly following drug administration. In conclusion, thalidomide showed poor activity, but acceptable toxicity, in patients with metastatic melanoma. Future studies should explore this agent in combination with other biological agents or cytotoxic agents, such as temozolomide.

The efficacy of weekly paclitaxel in androgen-independent prostate cancer and its addictive cytotoxicity with anthracycline derivatives led us to determine the safety and efficacy of a weekly schedule of paclitaxel and epirubicin. Between October 2000 and November 2002, 32 patients were enrolled in this study. Patients characteristics included a median age of 72 years (range 68-77), adequate hepatic, cardiac, renal and bone marrow functions, ECOG performance status of 1-2, and no prior chemotherapy. All patients had received hormonal manipulation and seven patients (22%) had received prior palliative radiation therapy. The regimen consisted of paclitaxel 70 mg/m2 i.v. infusion for 2 h and epirubicin 30 mg/m2 in bolus every week. Treatment was continued for 3 months or until disease progression or unacceptable toxicity were observed. During the study, prostate-specific antigen (PSA) was monitored and response was defined as a 50% reduction in PSA levels, to be confirmed 4 weeks later. Thirty-one patients were evaluable for toxicity and 21 for objective response. Seventeen patients (57%) had a decline above 50% in PSA level that lasted more than 4 weeks with a median time to PSA progression and a median duration of PSA response of approximately 5.5 months. Ten of the 21 patients with measurable disease (47%) had a confirmed objective response (one complete response and 20 partial responses). Thirteen of 25 symptomatic patients (56 %) had improvement in pain. The median time to disease progression was 7.6 months and the median survival was 12.9. The most prominent grade 3 toxicities were reversible myelosuppression and fatigue. Nausea, vomiting, diarrhea and peripheral edema were minimal. No evidence of cardiac toxicity was recorded. Alopecia was frequent, but reversible, in all patients. We conclude that despite the small sample size, this study demonstrates that the combination of weekly paclitaxel and epirubicin is a well-tolerated regimen for androgen-independent prostate cancer. The results imply that a combination of these agents in a weekly schedule may have clinical potential in prostate cancer treatment.

We assessed long-term side effects with characteristics of female climacteric disorders in prostate cancer patients treated with luteinizing hormone-releasing hormone (LHRH) agonists. Such side effects are not considered to be serious, though they can significantly affect patient quality of life. Sixty-four prostate cancer patients treated with LHRH agonists and 30 benign prostatic hyperplasia patients, as a control group, were surveyed by questionnaire. The median age of the cancer patients was 74.9 years old, ranging from 60 to 94 years, and the median LHRH agonist dosing period was 16.5 months, ranging from 1 to 64 months. The results of the questionnaires were compared between the patients and the controls, as well as between different variables. Sixty (93.8%) of 64 patients claimed symptoms similar to female climacteric disorders. Further, more than 50% of the symptoms included in the questionnaire were reported by 14 (21.9%) of the patients. Symptoms reported by the patients were more severe than those by the controls. Hot flashes, sleep disturbance, and fatigue recorded high scores in the patient questionnaires as compared with those of the controls. In addition, as the term of LHRH agonist use increased, complaints of sweating or coldness in hands and feet increased. Patients without bone metastasis frequently experienced heaviness in the head and headaches compared to those with bone metastasis. The results of our questionnaire-based outcome study showed that side effects similar to female climacteric disorders in prostate cancer patients treated with LHRH agonists were more severe than in the control group, which could be detrimental to quality of life and general well-being.

Androgen-deprivation therapy (ADT) is indicated for the treatment of metastatic prostate cancer and locally advanced disease. In addition to sexual side effects, long-term ADT results in several other changes, including hot flashes; gynecomastia; changes in body composition, metabolism, and the cardiovascular system; osteoporosis; anemia; psychiatric and cognitive problems; and fatigue and diminished quality of life. This review discusses these complications of ADT and treatments aimed at reducing them. It is important for clinicians to anticipate these effects and to initiate measures to prevent or minimize them in order to maintain quality of life in prostate cancer survivors.
