Long-term outcomes of high-dose-rate brachytherapy for intermediate- and high-risk prostate cancer with a median follow-up of 10 years.

OBJECTIVE: To evaluate the long-term outcomes of high-dose-rate (HDR) brachytherapy for patients with intermediate- and high-risk prostate cancer. SUBJECTS AND METHODS: We retrospectively analysed a prospective longitudinal cohort database including a single-surgeon series of 507 consecutive men treated with external beam radiotherapy and an HDR prostate brachytherapy boost between August 2000 and December 2009. The risk factors used were based on the D'Amico classification. We measured the incidence of no biochemical evidence of disease (bNED) based on the Phoenix definition of failure (nadir PSA + 2 ng/mL). We also reviewed the incidence of urethral stricture in this cohort. RESULTS: With minimum and median follow-ups of 6 and 10.3 years, respectively, the bNED rates for men with intermediate- and high risk disease were 93.3% and 74.2%, respectively, at 5 years and 86.9% and 56.1%, respectively, at 10 years. The 10-year bNED rate for men with only one intermediate-risk factor was 94%, whereas for patients with all three high-risk factors it was 39.5%. The overall urethral stricture rate was 13.6%. Before 2005, the urethral stricture rate was 28.9% and after January 2005 it was 4.2%. For the 271 men with a minimum follow-up of 10 years the actuarial 10-year prostate cancer-specific survival rate was 90.8% and the actuarial overall survival rate was 86.7%. CONCLUSIONS: For men with intermediate- or high-risk prostate cancer features, who are considered not suitable for, or wish to avoid a radical prostatectomy, HDR prostate brachytherapy remains an appropriate treatment option. From December 2004, prevention strategies decreased the risk of post-brachytherapy urethral strictures.

Urinary tract cancers: An overview for general practice.

Urinary tract cancers are common and comprise a gamut of lesions ranging from small benign tumors to aggressive neoplasms with high mortality. The predominant urinary tract malignancy is bladder cancer. The clinical challenge is early detection and adequate follow-up because recurrence is high and delayed diagnosis is associated with poor prognosis. Primary care physicians form a key part of the management apparatus for these patients and may be responsible for ensuring adequate ongoing surveillance. This article aims to outline the evaluation of patients in whom urinary tract cancer is suspected and briefly review the general principles of treatment.

Resistant hypertension: an approach to management in primary care.

Hypertension is widely encountered in family medicine. Despite its prevalence, many patients have uncontrolled or difficult-to-control blood pressure. Resistant hypertension is defined as hypertension that is poorly responsive to treatment and requires the use of multiple medications to achieve acceptable blood pressure ranges. It may be a consequence of secondary hypertension or have no identifiable cause. Resistant hypertension is important to recognise because it places patients at risk of end-organ damage. Primary care physicians should be aware of the therapeutic approach for hypertension when traditional therapy fails. This article aims to familiarise readers with the evaluation and management of resistant hypertension by outlining the most recent evidence-based treatment options.

Electrical burn causing a unique pattern of neurological injury.

Neurological involvement is not uncommon in patients who sustain electrical injury. The exact mechanism of nervous system damage following electrical trauma is not fully understood. The gamut of possible neurologic manifestations following electrical injury is diverse. This case report describes a young man with a unique pattern of neurological injury following an electrical burn. The combination of brachial plexopathy, partial Horner's syndrome, and phrenic nerve palsy secondary to electrical injury has not been previously described in the literature.
