Watchful waiting and quality of life among prostate cancer survivors in the Physicians' Health Study.

ABSTRACT: We examined patient reported outcomes among patients with prostate cancer treated with watchful waiting in a nationwide cohort.We collected treatment information and patient reported outcomes from 1,230 patients with prostate cancer diagnosed with T1-T2 prostate cancer in the Physicians' Health Study, of whom 125 were initially treated with watchful waiting. Cox proportional hazards regression was used to identify predictors of treatment initiation among patients on watchful waiting. Logistic regression was used to calculate the OR and 95% CI to assess disease targeted quality of life by initial treatment or watchful waiting.At a mean 7.3-year followup 41% of patients on watchful waiting remained free of treatment while 34% had received radiotherapy or brachytherapy, 16% had received primary hormonal therapy and 10% had undergone prostatectomy. Younger age, higher clinical stage, higher Gleason score and higher prostate specific antigen at diagnosis predicted progression to treatment. Watchful waiting compared to immediate treatment was associated with less urinary incontinence (3.5% vs 10%) and impotence (68% vs 78%) but more common obstructive urinary symptoms (22% vs 13%) on univariate analysis (each p <0.05). Incontinence and impotence differences remained significant after adjusting for age, comorbidity and time after cancer diagnosis. Quality of life outcomes in men who underwent delayed treatment after initially waiting were not worse than in men who underwent immediate treatment.Findings suggest quality of life benefits after watchful waiting in select patients with early stage prostate cancer compared to men treated immediately after diagnosis. Younger age and greater cancer severity at diagnosis predicted progression to treatment.

Project description:ObjectiveLittle is known about clinicians' decision-making about decreasing active surveillance (AS) testing/converting patients to watchful waiting (WW), nor are there any guidelines. The objective of this study was to identify factors that clinicians consider when decreasing AS testing/converting to WW for men with prostate cancer.DesignExploratory qualitative study.SettingAll participants practiced in various institutions in the USA.ParticipantsEligible clinicians had to provide clinical care for patients with prostate cancer in the USA and speak English. Clinicians could be either urologists or radiation oncologists. Of the 24 clinicians, 83% were urologists representing 11 states, 92% were men and 62% were white.MethodsThis qualitative study used data from semi-structured interviews. Purposive sampling was used to ensure geographical variation in the USA. Data collection continued until thematic saturation was achieved. Framework analysis guided coding and identification of themes. Two researchers coded all transcripts independently, met to discuss and reached consensus.ResultsInterviews with clinicians demonstrated that testing or monitoring for AS or transitioning to WW is happening in practice, whether intentionally or unintentionally. Decisions to decrease AS were personalised and tailored to patients' health status. Life expectancy was the dominant factor that influenced decision, but clinicians were generally hesitant to specify an age when they would decrease AS or transition to WW. Fear that poor adherence could lead to missed progression and concerns about the medico-legal issue of not doing enough were cited as barriers to decreasing AS.ConclusionsThese findings suggest that in certain situations, AS frequency is reduced or transitioned to WW, yet decisions appear to be inconsistent and there are no significant barriers. These findings could inform further areas to explore when drafting recommendations that consider patients' values and preferences when making decisions about decreasing AS/converting to WW.

Project description:BackgroundSurvival after childhood cancer has improved to more than 80% during the last few years, leading to an increased number of childhood cancer survivors. Cancer itself, or its treatment, may cause chronic health conditions, including somatic and mental sequelae, which may affect survivors' health-related quality of life (HRQoL).ObjectiveThe project PanCareLIFE aims to establish a large database with comprehensive data on childhood cancer survivors from different European countries, including data on HRQoL. Within PanCareLIFE, this study aims to describe HRQoL in survivors, investigate predictors of HRQoL, and describe the association of HRQoL with hearing and female fertility impairment. This paper describes the design of the HRQoL study, the origin of data, strategies for data collection, and sampling characteristics of survivors from each contributing country.MethodsA total of 6 institutions from 5 European countries (the Czech Republic, France, Germany, the Netherlands, and Switzerland) provided data on HRQoL assessed with the Short Form 36 and on relevant predictors. The central PanCareLIFE data center aggregated the data and harmonized the variables between the institutions. Survivors were eligible if they received a diagnosis of cancer according to the 12 main groups of the International Classification of Childhood Cancer, 3rd edition, or Langerhans cell histiocytosis; were aged ≤18 years at the time of diagnosis; were residents of the respective country at the time of diagnosis; had survived ≥5 years after cancer diagnosis; were aged ≥18 years at the time of the questionnaire survey; and did not refuse to registration in the national or local childhood cancer cohort.ResultsWe identified 24,993 eligible survivors. Of those, 19,268 survivors received a questionnaire and 9871 survivors participated, resulting in response rates of 9871/24,993 (39.50%) of eligible survivors and of 9871/19,268 (51.23%) invited survivors. Most participants were diagnosed with cancer between the ages of 10 and 14 years (3448/9871, 34.93%) or <5 years (3201/9871, 32.43%). The median age was 8 years. Of the 9871 participants, 3157 (31.97%) were survivors of leukemia, 2075 (21.02%) lymphoma, and 1356 (13.7%) central nervous system (CNS) tumors. Most participants (9225/9871, 93.46%) had no history of a subsequent tumor; 77.45% (7645/9871) received chemotherapy with or without other treatments. More than half (5460/9871, 55.31%) were aged 25 to 34 years at the time of the HRQoL study. Participating survivors differed from nonparticipants; participants were more often women, survivors of leukemia or lymphoma, and less frequently, survivors of CNS tumors than nonparticipants.ConclusionsPanCareLIFE successfully assessed HRQoL and its predictors in 9871 European survivors of childhood cancer. This large population will permit detailed investigations of HRQoL after childhood cancer, particularly the impact of hearing and female fertility impairment on HRQoL.International registered report identifier (irrid)RR1-10.2196/21851.
