Severity profiles in patients diagnosed of benign prostatic hyperplasia in Spain

[Benign prostatic hyperplasia]

Benign prostatic hyperplasia (BPH) is a histopathologic definition associated with enlargement of the prostate gland that causes obstruction of the lower urinary tract and manifests clinically with characteristic symptoms that are what bring patients for consultation. Urinary tract symptoms are common, especially in an increasingly aging population. Diagnosis and the decision on when and how to treat depend on the patient's quality of life and objective clinical parameters. An individualized, risk-based approach is necessary to guide conservative, pharmacologic, or surgical treatment.

Real-world therapeutic management and evolution of patients with benign prostatic hyperplasia in primary care and urology in Spain

OBJECTIVES

This study aimed to describe the real-world therapeutic management of patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) (LUTS/BPH) attending primary care and urology clinics in Spain.

METHODS

This observational, retrospective, multicentre study included men ≥50 years of age diagnosed with LUTS/BPH (≤8 years prior to study visit) (N = 670). Therapeutic management according to healthcare service (primary care vs. urology clinics) or progression criteria, proportion of patients with treatment change, patient profile according to therapy and evolution of LUTS severity were assessed.

RESULTS

Overall differences were noticed in the management of patients between healthcare service (P < .001) and with or without progression criteria (P < .05). Most patients received pharmacological treatment at diagnosis (70.7%; 474/670), which increased at study visit (81.6%; 547/670) with overall similar profiles between primary care and urology clinics for each therapy. α1-Blockers were the most used pharmacological treatment across healthcare settings at diagnosis (61.8%; 293/474) and study visit (51%; 279/547). Only 27.1% (57/210) of patients with progression criteria at diagnosis and 35.6% (99/278) at study visit received 5α-reductase inhibitor (5ARI) alone or in combination with a α1-blocker. Overall, most patients did not change treatment (60%; 402/670) with a trend of more patients worsening in symptoms when not receiving α1-blocker plus 5ARI combination therapy.

CONCLUSION

Most patients with LUTS/BPH received pharmacological treatment; however, most men with progression criteria did not receive a 5ARI alone or in combination. These results support the need to reinforce both primary care and urologists existing clinical guideline recommendations for the appropriate medical management of patients with LUTS/BPH.

Real-world assessment and characteristics of men with benign prostatic hyperplasia (BPH) in primary care and urology clinics in Spain

OBJECTIVES

To describe the real-world demographic and clinical characteristics of patients with lower urinary tract symptoms (LUTS) as a result of benign prostatic hyperplasia (BPH) in Spain.

METHODOLOGY

This observational, retrospective, multicentre study conducted in primary care and urology clinics in Spain included men aged ≥50 years diagnosed (≤8 years prior to study visit) with LUTS caused by BPH. The primary endpoint was demographic and clinical characteristics; secondary endpoints included disease progression and diagnostic tests across both healthcare settings.

RESULTS

A total of 670 patients were included (primary care: n = 435; urology: n = 235). Most patients had moderate/severe LUTS (74.6%) and prostate volume >30 cc (81.7%), with no differences between settings. More patients had prostate-specific antigen (PSA) ≥1.5 ng/mL in primary care (74.5%) versus urology (67.7%). Progression criteria were prevalent (48.9%). Clinical criteria were more commonly used than the International Prostate Symptom Score (IPSS) to evaluate LUTS at diagnosis (primary care: clinical criteria 73.0%; IPSS: 26.9%; urology: clinical criteria 76.5%; IPSS: 23.4%). Proportion of patients with moderate/severe LUTS at diagnosis was lower using clinical criteria than IPSS, and the proportion of patients with 'worsening' LUTS (diagnosis to study visit) was higher when using clinical criteria versus IPSS. In both healthcare settings, the most commonly used diagnostic tests were general and urological clinical history and PSA.

CONCLUSION

Demographic and clinical characteristics of patients with BPH in Spain were similar in primary care and urology; however, assessment criteria to evaluate LUTS severity differ and are not completely aligned with clinical guideline recommendations. Increased use of recommended assessments may enhance optimal BPH management.

Efficacy and safety of a fixed-dose combination of dutasteride and tamsulosin treatment (Duodart(®) ) compared with watchful waiting with initiation of tamsulosin therapy if symptoms do not improve, both provided with lifestyle advice, in the management of treatment-naïve men with moderately symptomatic benign prostatic hyperplasia: 2-year CONDUCT study results

OBJECTIVE

To investigate whether a fixed-dose combination (FDC) of 0.5 mg dutasteride and 0.4 mg tamsulosin is more effective than watchful waiting with protocol-defined initiation of tamsulosin therapy if symptoms did not improve (WW-All) in treatment-naïve men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression.

PATIENTS AND METHODS

This was a multicentre, randomised, open-label, parallel-group study (NCT01294592) in 742 men with an International Prostate Symptom Score (IPSS) of 8-19, prostate volume ≥30 mL and total serum PSA level of ≥1.5 ng/mL. Patients were randomised to FDC (369 patients) or WW-All (373) and followed for 24 months. All patients were given lifestyle advice. The primary endpoint was symptomatic improvement from baseline to 24 months, measured by the IPSS. Secondary outcomes included BPH clinical progression, impact on quality of life (QoL), and safety.

RESULTS

The change in IPSS at 24 months was significantly greater for FDC than WW-All (-5.4 vs -3.6 points, P < 0.001). With FDC, the risk of BPH progression was reduced by 43.1% (P < 0.001); 29% and 18% of men in the WW-All and FDC groups had clinical progression, respectively, comprising symptomatic progression in most patients. Improvements in QoL (BPH Impact Index and question 8 of the IPSS) were seen in both groups but were significantly greater with FDC (P < 0.001). The safety profile of FDC was consistent with established profiles of dutasteride and tamsulosin.

CONCLUSION

FDC therapy with dutasteride and tamsulosin, plus lifestyle advice, resulted in rapid and sustained improvements in men with moderate BPH symptoms at risk of progression with significantly greater symptom and QoL improvements and a significantly reduced risk of BPH progression compared with WW plus initiation of tamsulosin as per protocol.
