Psychological impact of serial prostate-specific antigen tests in Japanese men waiting for prostate biopsy

Prostate-specific antigen kinetics contributes to decision making for biopsy referral: the predictive implication for PSA retest in patients with elevated PSA levels

Background

It is common to repeat prostate-specific antigen (PSA) measurements for men with PSA elevation before prostate biopsy. In this scenario, they may have considerable psychological distress in fear of the presence of cancer until retests. We assessed possible clinical factors causing transient PSA rise and explored the parameters predictive of subsequent PSA change.

Methods

As interfering conditions, the history of ejaculation, bicycling, and any types of infections were assessed using the questionnaire. The pattern of PSA change was compared in association with the various clinical factors. Predictive significance of PSA kinetics such as coefficient of variation (CV) and PSA velocity (PSAV) for PSA values at retest was evaluated.

Results

The rate of reversion to the normal range was 38.3% at retest. The rate of 12.8% of men showed a large increase by ≥20%, whereas 38.2% of men showed a large decline by ≥20% from the baseline. Men with younger age (≤60 years), small prostate (<20 cc), and prior history of ejaculation or infections showed significantly larger PSA decrease than their counterparts. Those with large CV or PSAV before the baseline more frequently showed PSA decrease below the age-specific cutoff or decline by ≥10% from the baseline at retest. These parameters associated with PSA kinetics had independent predictive values for relevant PSA change at retest.

Conclusions

Ejaculation and any types of infections should be avoided before PSA tests. Men with large PSA fluctuation before the baseline are likely to show a significant PSA decrease at retest. This predictive information may help both physicians to determine whether to proceed to an immediate biopsy and patients to reduce their psychological burden.

'Is it painful'? A qualitative study on experiences of patients before prostate needle biopsy

OBJECTIVE

To assess the experiences and emotional reactions of men prior to receiving a prostate needle biopsy (PNB).

DESIGN

This was a qualitative study involving (1) material research and filter, (2) interviewer training, (3) cognitive semistructured interviews with open-ended questions, (4) data analysis, including translation and back translation and (5) group discussions to determine common themes in the data. All interviews were digitally audio-recorded. The thematic analysis was conducted by repeatedly reading the data manuscript and engaging in group discussion.

SETTING AND PARTICIPANTS

A total of 30 participants with suspected prostate cancer (PC) who were scheduled to receive a PNB were interviewed. Eligible participants were Chinese native men aged 51-77 years, and the study was conducted in China between September and December 2020. All participants were informed about the purpose of the study and provided written informed consent.

RESULTS

Four main themes were identified based on the interview content: (1) fear (of pain, adverse effects and bad results), (2) impact of lower urinary tract symptoms (on emotional impact, work and sleeping), (3) inner struggles (relating to hesitation, regret and embarrassment) and (4) lifestyle change (including diet, exercise and receipt of traditional Chinese medicine).

CONCLUSIONS

This patient cohort had a low level of knowledge about PC and PNB. Providing additional education about these topics would help to reduce patient fear and anxiety and improve experiences of the procedure.

Anxiety and depression associated with a positive prostate biopsy result: A comparative, prospective cohort study

Purpose

To investigate the course of anxiety and depression before and after transrectal ultrasound-guided prostate biopsy (TRUS-Bx) and in the postoperative 1st month when the histopathological biopsy result was obtained.

Methods

In between June 2017- January 2019, 204 patients who underwent TRUS-Bx and completed the questionnaires assessing anxiety and depression were included in the study. Questionnaires were completed immediately before the biopsy, immediately after the biopsy and at the end of the first month when the histopathological biopsy results were given. State-Trait Anxiety Inventory (STAI), Hospital Anxiety and Depression Scale (HADS) and perceived stress scale (PSS) forms were used to assess anxiety and depression. After the histopathological examination patients were divided into two groups as patients without cancer (Group 1) and with cancer (Group 2). Data was compared between the groups.

Results

PSA level was negatively correlated with STAI TX-1 scores of the patients immediately after TRUS-Bx, whereas it was positively correlated with STAI TX-1 and TX-2 30 days after the TRUS-Bx. PSA level was positively correlated with HADS-A and HADS-D scores immediately before and 30 days after TRUS-Bx. Biopsy results showed a significant difference in 30 day post-biopsy related data. STAI TX-1, STAI TX-2, HADS-A, HADS-D and PSS scores were higher in Group 2 compared with Group 1.

Conclusions

Pre-biopsy anxiety disappeared after bx, but there was a significant increase in anxiety and depression in patients after the diagnosis of malignancy. Patients were seriously concerned about the diagnosis of prostate cancer.
