Setting an Agenda for Assessment of Health-related Quality of Life Among Men with Prostate Cancer on Active Surveillance: A Consensus Paper from a European School of Oncology Task Force

Patient-Factors Influencing the 2-Year Trajectory of Mental and Physical Health in Prostate Cancer Patients

This study aimed to examine the physical and mental Quality of Life (QoL) trajectories in prostate cancer (PCa) patients participating in the Pros-IT CNR study. QoL was assessed using the Physical (PCS) and Mental Component Score (MCS) of Short-Form Health Survey upon diagnosis and two years later. Growth mixture models were applied on 1158 patients and 3 trajectories over time were identified for MCS: 75% of patients had constantly high scores, 13% had permanently low scores and 12% starting with low scores had a recovery; the predictors that differentiated the trajectories were age, comorbidities, a family history of PCa, and the bowel, urinary and sexual functional scores at diagnosis. In the physical domain, 2 trajectories were defined: 85% of patients had constantly high scores, while 15% started with low scores and had a further slight decrease. Two years after diagnosis, the psychological and physical status was moderately compromised in more than 10% of PCa patients. For mental health, the trajectory analysis suggested that following the compromised patients at diagnosis until treatment could allow identification of those more vulnerable, for which a level 2 intervention with support from a non-oncology team supervised by a clinical psychologist could be of help.

Cross-cultural differences in men on active surveillance' anxiety: a longitudinal comparison between Italian and Dutch patients from the Prostate cancer Research International Active Surveillance study

Background

Men diagnosed with localized prostate cancer (PCa) on active surveillance (AS) have shown to cope with anxiety caused by living with an ‘untreated cancer’ and different factors can influence the tolerance level for anxiety in these patients. The present study analyzes Italian (Milan) and Dutch (Rotterdam) men prospectively included in the Prostate cancer International Active Surveillance (PRIAS) trial, aiming to explore whether socio-demographic factors (i.e. age, relationship status, education, nationality) may be relevant factors in conditioning the level of anxiety at AS entry and over time.

Methods

Italian and Dutch men participating in the IRB-approved PRIAS study, after signing an informed consent, filled in the Memorial Anxiety Scale for PCa (MAX-PC) at multiple time points after diagnosis. A linear mixed model was used to assess the relationship between the level of patient’s anxiety and time spent on AS, country of origin, the interaction between country and time on AS, patients’ relationship status and education, on PCa anxiety during AS.

Results

823 MAX-PC questionnaires were available for Italian and 307 for Dutch men, respectively. Median age at diagnosis was 64 years (IQR 60–70 years) and did not differ between countries. On average, Dutch men had a higher total MAX-PC score than Italian men. However, the level of their anxiety decreased over time. Dutch men on average had a higher score on the PCa anxiety sub-domain, which did not decrease over time. Minimal differences were observed in the sub-domains PSA anxiety and fear of recurrence.

Conclusion

Significant differences in PCa anxiety between the Italian and Dutch cohorts were observed, the latter group of men showing higher overall levels of anxiety. These differences were not related to the socio-demographic factors we studied. Although both PRIAS-centers are dedicated AS-centers, differences in PCa-care organization (e.g. having a multidisciplinary team) may have contributed to the observed different level of anxiety at the start and during AS.

Trial registration This study is registered in the Dutch Trial Registry (www.trialregister.nl) under NL1622 (registration date 11-03-2009), ‘PRIAS: Prostate cancer Research International: Active Surveillance—guideline and study for the expectant management of localized prostate cancer with curative intent’.

Supporting Patients With Untreated Prostate Cancer on Active Surveillance: What Causes an Increase in Anxiety During the First 10 Months?

Background

The psychological burden possibly deriving from not immediately undergoing radical treatment for prostate cancer (PCa) could be a potential disadvantage of active surveillance (AS), especially in the eve of some relevant clinical exams [i.e., re-biopsy, prostate-specific antigen (PSA) test, and medical examination]. Even if it is known from the literature that the majority of PCa men in AS do not report heightened anxiety, there is a minority of patients who show clinically significant levels of anxiety after diagnosis. The present study aimed to investigate if demographic, clinical, and psychological variables at the entrance in AS (T0) were associated with the risk of developing clinically significant PCa-related anxiety 2 months before the first re-biopsy (T1) and to offer psychological support to improve quality of life (QoL).

Materials and Methods

A total of 236 patients participated in the PCa Research International: AS (PRIAS) protocol and in PRIAS-QoL study. Demographic/clinical features, health-related QoL domains, coping with cancer, PCa-related anxiety [Memorial Anxiety Scale for PCa (MAX-PC)], personality traits, and decision-making-related factors were assessed at T0. MAX-PC was also administered at T1. PCa-related anxiety at T1 was considered to be of clinical significance if the MAX-PC score was ≥1.5. Multivariable logistic regression coupled to bootstrap was used to detect factors associated with high levels of anxiety.

Results

The median age was 64.4 years. Fifty-six patients (24%) reported MAX-PC total score above the cutoff. Three factors were associated with a high level of PCa anxiety at T1: anxious preoccupation [odds ratio (OR) = 4.36], extraversion (OR = 1.9), and prostate-related symptoms (median OR = 0.46). Physical well-being was associated with a low PCa anxiety subscale (median OR = 0.15); neuroticism and functional well-being were associated with PSA anxiety (median OR = 7.05 and 0.73, respectively). Neuroticism and helplessness/hopelessness were associated with fear of progression (median OR = 18.1 and 5.8, respectively).

Conclusion

Only a partial portion of the sample experienced significant levels of anxiety after 10 months. Psychological assessment should be routinely conducted to detect risk factors (i.e., anxious preoccupation, extraversion) for increased anxiety, offering tailored psychological interventions aimed at promoting interpersonal awareness and emotional well-being.

How do prostate cancer patients navigate the active surveillance journey? A 3-year longitudinal study

OBJECTIVE

To investigate whether prostate cancer (PCa) patients' coping strategies (i.e., fighting spirit, anxious preoccupation, fatalism, helplessness/hopelessness, and avoidance) significantly change during the first 3-year follow-up period of active surveillance (AS).

MATERIALS AND METHODS

Altogether, 104 patients on AS completed the Mini-Mental Adjustment to Cancer (Mini-MAC) at baseline (T0), at 10 and 12 months after diagnostic biopsy (T1 and T2, respectively) and then at 24- (T3) and 36-month (T4) follow-up. Paired samples T test was used to detect statistically significant changes over time. Changes ≥ 1 point (or ≤ - 1) were hypothesized to be clinically relevant.

RESULTS

During the first 3 years on AS, men experienced decreased anxiety, avoidance thoughts/behaviors, and fight-against-cancer attitudes, and these changes were found to be statistically significant. When considering clinically significant changes between inclusion in AS (T0) and 3-year follow-up (T4), avoidance decreased in 19% of patients.

CONCLUSIONS

Most patients were observed to have adopted functional coping strategies at baseline, which were maintained through the first 3 years on AS. Overall, men on AS may perceive increasing control over their cancer and comfort with the AS protocol over time and experience slight decreases in anxious preoccupation, cancer-related avoidance thoughts and behaviors, and fight-against-cancer reactions. For those men who find it difficult to cope with AS, psychological monitoring and interventions could be helpful throughout the monitoring journey.

Making Active Surveillance a path towards health promotion: A qualitative study on prostate cancer patients' perceptions of health promotion during Active Surveillance

OBJECTIVE

Health promotion is a key aspect for health outcomes of prostate cancer (PCa) patients. However, it has been poorly explored among patients following monitoring programmes, for example Active Surveillance (AS). This study aimed to explore PCa patients' perceptions of health promotion during AS.

METHODS

An explorative qualitative research design was adopted. Four focus groups were used to collected data from 24 men enrolled in the Prostate Cancer Research International: AS (PRIAS) protocol. A thematic analysis with an inductive approach was performed.

RESULTS

Participants described promoting health during AS as challenged by mental, age-related, informational and organisational issues. It was reported as an effort to stay in the present with a positive outlook, despite the worries for the future ("the mental theme"). It was perceived as impacted by being older and having to manage physical and mental struggles related to age ("the life-course theme"). It depended, in their accounts, on obtaining reliable information and personalised education ("the educational theme"). Finally, it was related on taking responsibility on the care process ("the organisational theme").

CONCLUSION

This study suggested ways of promoting health during AS that can help healthcare professionals and organisations building a "health-promoting AS," able to improve overall health outcomes.

Italian cultural adaptation of the Memorial Anxiety for Prostate Cancer scale for the population of men on active surveillance

Purpose:

The Memorial Anxiety Scale for Prostate Cancer (MAX-PC) is a self-report questionnaire that was developed in English to assess prostate cancer (PCa)-related anxiety. The aim of this study was to perform a cultural adaptation for the tool to be used in a population of Italian men on active surveillance (AS).

Methods:

A total of 222 patients with localized PCa who were recruited for the Prostate Cancer Research International: Active Surveillance (PRIAS) protocol completed the MAX-PC. Psychometric analysis was performed to assess reliability indexes. A Spearman rank correlation was used to test the association between MAX-PC scales and other questionnaires and was used for longitudinal analysis.

Results:

Cronbach coefficients and item to total correlation demonstrated good internal consistency. Some items related to the repetition of the PSA test showed a large floor effect and thus were poorly effective in measuring anxiety for PSA testing in patients on AS. Confirmatory factor analysis partly failed to reproduce the structure of the original version. A modified version of MAX-PC, excluding the items with a large floor effect, was thus considered for AS patients. Factor analysis on this version demonstrated considerable consistency with the presence of 3 subscales: anxiety related to PCa, anxiety related to PSA testing, and anxiety related to the fear of tumor progression. Longitudinal analysis showed an acceptable validity over time. The MAX-PC was correlated with the anxious preoccupation subscale of the Mini-Mental Adjustment to Cancer scale.

Conclusions:

A slightly modified version of the MAX-PC was developed for use in Italian men on AS. This instrument appears to be a valid and reliable tool that measures anxiety in men with PCa who are enrolled in AS programs.

Quality of life in active surveillance and the associations with decision-making-a literature review

Several studies have been conducted on the quality of life (QoL) in men with low risk prostate cancer (PCa) who choose active surveillance (AS). While recent reviews have shown a lack of consistency among the available QoL-studies, a few key points have been identified, including decision-making (DM)-related issues and their potential effect on QoL. The importance of this theme has also been recently highlighted by the international task force of the European School of Oncology. However, to our knowledge, there are no studies that have specifically marshalled scientific knowledge on the association between DM and QoL among men with low-risk PCa undergoing AS. We performed a literature review to fill this gap, taking a systematic approach to retrieving and selecting articles that included both DM and QoL measures. Among the 272 articles retrieved, we selected nine observational, quantitative articles with both DM and QoL measures. The most considered DM aspects within these studies were decisional conflict and preference for the patient’s role in the DM process, as well as health-related QoL aspects. The studies included 42 assessments of the relationship between an empirical measure of DM and an empirical measure of QoL. Among these assessments, 23 (55%) were both positive and significant. They mostly concerned the relationship between patient-related (decisional self-efficacy, decisional control and knowledge) and external (presence of social support, collaborative role within the DM process, and influence of different physicians) DM aspects, as well as the QoL after choice. The findings of these studies revealed key challenges to research and clinical practice related to DM and QoL in AS. These include adopting a person-centred perspective where clinicians, caregivers and their interactions are also included in evaluations and where the psychosocial existential experience of individuals within the DM and AS journey is considered. Much more attention needs to be paid to the DM process after diagnosis, as well as to all the other moments where patients may have to or want to review their decision. Healthcare professionals play a key role in enabling men to make informed decisions and to take care of their health and well-being during AS. There is still work that needs to be done in training healthcare professionals from different disciplines to work together in a model of shared DM and AS tailored to the needs of low-risk PCa patients and their family members.
