Neurologic Complications of Prostate Cancer - Article

ABSTRACT: Neurologic complications continue to pose problems in patients with metastatic prostate cancer. From 15 to 30 percent of metastases are the result of prostate cancer cells traveling through Batson's plexus to the lumbar spine. Metastatic disease in the lumbar area can cause spinal cord compression. Metastasis to the dura and adjacent parenchyma occurs in 1 to 2 percent of patients with metastatic prostate cancer and is more common in those with tumors that do not respond to hormone-deprivation therapy. Leptomeningeal carcinomatosis, the most frequent form of brain metastasis in prostate cancer, has a grim prognosis. Because neurologic complications of metastatic prostate cancer require prompt treatment, early recognition is important. Physicians should consider metastasis in the differential diagnosis of new-onset low back pain or headache in men more than 50 years of age. Spinal cord compression requires immediate treatment with intravenously administered corticosteroids and pain relievers, as well as prompt referral to an oncologist for further treatment.

Treatment Options for Prostate Cancer: Evaluating the Evidence - Article

ABSTRACT: Controversy surrounds the management options for localized prostate cancer-conservative management, prostatectomy, and radiation. Choosing among these options is difficult because of long-term side effects that include sexual, urinary, and bowel dysfunction. Some recent studies suggest that patients who have chosen treatment (i.e., radical prostatectomy or radiation) have longer disease-free survival compared with patients who have chosen conservative management (i.e., watchful waiting). However, several biases may artificially enhance the perceived value of treatment and make the interpretation of studies on treatment outcomes difficult. Sources of bias include lead time, length time, and patient selection. Because of the uncertain efficacy of management options and the risk of long-term treatment complications, family physicians need to engage their patients in the decision-making process.

Prostate Cancer Screening: The Continuing Controversy - Article

ABSTRACT: Prostate cancer is the second most common cancer in men, with a lifetime prevalence of 17 percent. Prostate cancer symptoms generally occur in advanced stages, making early detection desirable. Digital rectal examination and prostate-specific antigen testing are the most commonly used screening tools. The goal of screening is to detect clinically significant prostate cancers at a stage when intervention reduces morbidity and mortality; however, the merits and methods of screening continue to be debated. Prostate-specific antigen levels may be less than 4 ng per mL in 15 to 38 percent of men with cancer, indicating a high false-negative rate. The positive predictive value of the prostate-specific antigen test is approximately 30 percent; therefore, less than one in three men with an abnormal finding will have cancer on biopsy. These limitations of the prostate-specific antigen test have led to variations designed to improve its accuracy (e.g., age- and race-specific cutoffs, free prostate-specific antigen tests); however, none of these modifications have been widely adopted because of unclear benefits. Although treatments have improved in the past two decades, therapy for prostate cancer is not benign and may lead to urinary incontinence, sexual dysfunction, or bowel dysfunction. New evidence affecting screening recommendations continues to accumulate, and two large randomized controlled trials of screening will be completed in the next few years. Current guidelines recommend an individualized, targeted, patient-centered discussion to facilitate a shared decision about screening plans.

Cancer Screening in the Older Patient - Article

ABSTRACT: Although there are clear guidelines that advise at what age to begin screening for various cancers, there is less guidance concerning when it may be appropriate to stop screening. The decision to stop screening must take into account patients' age; overall health and life expectancy; the natural history of the disease; and the risks, expense, and convenience of the screening test, and any subsequent testing and treatment. The U.S. Preventive Services Task Force and the American Academy of Family Physicians suggest that Papanicolaou smears can be discontinued in women at 65 years of age, provided they have had adequate recent normal screenings. Evidence suggests that cessation of breast cancer screening at approximately 75 to 80 years of age is appropriate, although American Geriatric Society guidelines recommend cessation at a more advanced age. Studies support continuing colon cancer screening until approximately 75 years of age in men and 80 years of age in women for patients without significant comorbidities. Prostate cancer screening, if conducted at all, may be discontinued at approximately 75 years of age in otherwise healthy men. Ultimately, the decision to screen or to discontinue screening must be made after careful discussion with each patient, using evidence-based guidelines and individual patient preferences.
