Hypothesis
Androgen deprivation may have an impact on cognitive performances in prostate cancer patients, especially on attention and memory.
Conclusion
Healthy prostate cancer patients treated with androgen deprivation in connection with curative radiotherapy maintain their cognitive functioning.
Supporting Evidence
- Patients showed significant improvement in episodic memory measures of object recall and in semantic memory.
- At baseline, the AD group performed at a lower level than the control group in immediate memory and visuomotor tasks.
- During the treatment, patients reported increased fatigue and declines in sexual functioning.
Takeaway
This study looked at how a treatment for prostate cancer affects thinking skills. It found that while the treatment can make some things harder, patients can still think well after a year.
Methodology
Cognitive testing was conducted on three occasions in 25 men receiving neo+adjuvant androgen deprivation therapy for 12 months.
Potential Biases
The subjective reports of cognitive function may not always align with objective test results.
Limitations
The study used normal controls at baseline as a reference group, which may not account for all individual variability.
Participant Demographics
The mean age of patients was 64.4 years, with a majority having T3 tumors.
