Adverse metabolic consequences of androgen deprivation therapy (ADT) on Asian patients with prostate cancer: Primary results from the real-life experience of ADT in Asia (READT) study.

BACKGROUND: Androgen deprivation therapy (ADT) use in prostate cancer (PCa) has seen a rising trend. We investigated the relationship between ADT and adverse changes in metabolic parameters in an Asian population. METHODS: This is an international prospective multicenter single-arm cohort yielded from the real-life experience of ADT in Asia (READT) registry. Consecutive ADT-naïve patients diagnosed of PCa and started on ADT were prospectively recruited from 2016 and analyzed. Baseline patient characteristics, PCa disease status, and metabolic parameters were documented. Patients were followed up at 6-month interval for up to 5 years. Metabolic parameters including body weight, lipid profiles, and glycemic profiles were recorded and analyzed. RESULTS: 589 patients were eligible for analysis. ADT was associated with adverse glycemic profiles, being notable at 6 months upon ADT initiation and persisted beyond 1 year. Comparing to baseline, fasting glucose level and hemoglobin A1c level increased by 4.8% (p < 0.001) and 2.7% (p < 0.001), respectively. Triglycerides level was also elevated by 16.1% at 6th month and by 20.6% at 12th month compared to baseline (p < 0.001). Mean body weight was 1.09 kg above baseline at 18th month (p < 0.001). CONCLUSION: ADT was associated with adverse metabolic parameters in terms of glycemic profiles, lipid profiles, and body weight in the Asian population. These changes developed early in the treatment and can persist beyond the first year. Regular monitoring of the biochemical profiles during treatment is paramount in safeguarding the patients' metabolic health.

Early postoperative outcome of bipolar transurethral enucleation and resection of the prostate.

OBJECTIVES: To report the early postoperative outcome of bipolar transurethral enucleation and resection of the prostate. Our results were compared with those published from various centres. SETTING: Regional hospital, Hong Kong. PATIENTS: A total of 28 consecutive patients who had undergone bipolar transurethral enucleation and resection of the prostate by a single surgeon between January and June 2014. All patients were evaluated preoperatively by physical examination, digital rectal examination, transrectal ultrasonography, and laboratory studies, including measurement of haemoglobin, sodium, and prostate-specific antigen levels. Patients were assessed perioperatively and at 4 weeks and 3 months postoperatively. RESULTS: The mean resected specimen weight of prostatic adenoma in 28 patients was 48.2 g with a mean enucleation and resection time of 13.6 and 47.7 minutes, respectively. There was a mean decrease in serum prostate-specific antigen by 85.9% (from 6.4 ng/mL to 0.9 ng/mL) postoperatively. Prostate volume was decreased by 68.2% (from 71.9 cm(3) to 22.9 cm(3)) at 4 weeks postoperatively. The mean postoperative haemoglobin drop was 11.5 g/L. The rate of transient urinary incontinence at 3 months was 3.6%. Patients who underwent bipolar transurethral enucleation and resection of the prostate had a short catheterisation time and hospital stay, which is comparable to conventional transurethral resection of the prostate. CONCLUSIONS: Bipolar transurethral enucleation and resection of the prostate should become the endourological equivalent to open adenomectomy with fewer complications and short convalescence. The technique of bipolar transurethral enucleation and resection of the prostate can be acquired safely with a relatively short learning curve.
