Brief summary

This study will aim to explore men's reasons for transitioning from active surveillance to further treatment in prostate cancer management, and the factors which may have contributed to this decision. Who is it for? Men eligible for this study must be registered on the South Australian Prostate Cancer Clinic Outcomes Collaborative (SA-PCCOC) or the Prostate Cancer Outcomes Registry in Victoria (PCOR-VIC). Eligible men will have been diagnosed with prostate cancer from 2014 - 2019 and aged 75 or younger at diagnosis. In addition, you have previously consented to registry data collection and questionnaires. Study details All participants will be required to complete a one-time survey (sent via mail but may be completed on paper, online, or via telephone). This survey consists of questions relating to social-ecological factors (i.e., personal, social, community, organisation, policy) and your experience on active surveillance. It is hoped this research will provide further insight into the psychosocial factors that influence men to actively seek treatment prior to disease progression.

Interventions

This is a case-control observational study. Cases will consist of prostate cancer patients who transitioned from active surveillance to active treatment without evidence of disease progression. They will be identified through the South Australian Prostate Cancer Clinic Outcomes Collaborative (SA-PCCOC) and the Prostate Cancer Outcomes Collaborative in Victoria (PCOR-VIC). All participants will complete a one-time survey (sent via mail but may be completed on paper, online, or via telephone), wh

This is a case-control observational study. Cases will consist of prostate cancer patients who transitioned from active surveillance to active treatment without evidence of disease progression. They will be identified through the South Australian Prostate Cancer Clinic Outcomes Collaborative (SA-PCCOC) and the Prostate Cancer Outcomes Collaborative in Victoria (PCOR-VIC). All participants will complete a one-time survey (sent via mail but may be completed on paper, online, or via telephone), which takes approximately 20 minutes to complete. This survey consists of research team developed questions and validated measures and aims to explore the social-ecological factors (i.e., personal, social, community, organisation, policy) which may influence men's experiences on active surveillance and their decision to transition to treatment (particularly for when disease progression has not yet occurred). A priming letter and reminder letter will be sent 1-2 weeks prior to and after the study materials are sent. To participate, participants must provide consent for their information stored on the registry to be accessed and complete the survey. A consent form and study information will be provided with the survey, along with a reply-paid envelope.

Inclusion criteria

Eligible men will be identified by the prostate cancer registries involved in the study; The South Australian Prostate Cancer Clinical Outcomes Collaborative (SA-PCCOC) and the Victorian Division of the Prostate Cancer Outcomes Registry (PCOR-VIC). The men must meet the following criteria: - Diagnosed with prostate cancer from 2014 - 2019 - Aged 75 or younger at diagnosis - The patient is alive and previously consented to registry data collection/questionnaire receiving - Commenced active surveillance after diagnosis (i.e., chosen treatment) - May have transitioned to active treatment after a period of active surveillance (no treatment within 10 months of diagnosis) Note: Disease progression is considered to have occurred if: - Follow-up biopsy shows Gleason of 7 or more, OR - Follow-up biopsy has 2 or more positive cores, OR - PSA has doubled within 3 years. Note: Active surveillance is operationalised as: - A coding of active surveillance as the treatment type on the registry - A period of time after diagnosis of low-intermediate risk prostate cancer (see D'Amico Risk Classifications) in which the patient did not receive active treatment, but rather received at least 1 follow-up PSA test/DRE/biopsy
