Are population-based patient-reported outcomes associated with overall survival in patients with advanced pancreatic cancer?

ABSTRACT: BACKGROUND:Advanced pancreatic cancer (APC) patients often have substantial symptom burden. In Ontario, patients routinely complete the Edmonton Symptom Assessment Scale (ESAS), which screens for nine symptoms (scale: 0-10), in cancer clinics. We explored the association between baseline patient-reported outcomes, via ESAS, and overall survival (OS). METHODS:Advanced pancreatic cancer patients with ESAS records prior to receiving publicly funded drugs from November 2008 to March 2016 were retrospectively identified from Cancer Care Ontario's administrative databases. We examined three composite ESAS scores: total symptom distress score (TSDS: 9 symptoms), physical symptom score (PHS: 6/9 symptoms), and psychological symptom score (PSS: 2/9 symptoms); Composite scores greater than defined thresholds (TSDS ?36, PHS ?24, PSS ?8) were considered as high symptom burden. Crude OS was assessed using Kaplan-Meier method. Hazard ratios (HRs) were assessed using multivariable Cox models. Analysis was repeated in a sub-cohort with Eastern Cooperative Oncology Group (ECOG) status and metastasis. RESULTS:We identified 2199 APC patients (mean age 64 years, 55% male) with ESAS records prior to receiving chemotherapy. Crude median survival was 4.5 and 7.3 months for high and low TSDS, respectively. High TSDS was associated with lower OS (HR = 1.47, 95% CI: 1.33, 1.63). In the sub-cohort (n = 393) with ECOG status and metastasis, high TSDS was also associated with lower OS (HR = 1.34, 95% CI: 1.04, 1.73). Similar trends were observed for PHS and PSS. CONCLUSIONS:Higher burden of patient-reported outcome was associated with reduced OS among APC patients. The effect was prominent after adjusting for ECOG status.

Project description:PURPOSE:Pancreatic cancer and its treatments impact patients' symptoms, functioning, and quality of life. Content-valid patient-reported outcome (PRO) instruments are required to assess outcomes in clinical trials. This study aimed to: (a) conceptualise the patient experience of pancreatic cancer; (b) identify relevant PRO instruments; (c) review the content validity of mapped instruments to guide PRO measurement in clinical trials. METHODS:Qualitative literature and interviews with clinicians and patients were analysed thematically to develop a conceptual model of patient experience. PRO instruments were reviewed against the conceptual model to identify gaps in measurement. Cognitive debriefing explored PRO conceptual relevance and patients' understanding. RESULTS:Patients in the USA (N?=?24, aged 35-84) and six clinicians (from US and Europe) were interviewed. Pre-diagnosis, pain was the most frequently reported symptom (N?=?21). Treatments included surgery, radiation, chemotherapy, and immunotherapy. Surgery was associated with acute pain and gastrointestinal symptoms. Chemotherapy/chemoradiation side effects were cyclical and included fatigue/tiredness (N?=?21), appetite loss (N?=?15), bowel problems (N?=?15), and nausea/vomiting (N?=?15). Patients' functioning and well-being were impaired. The literature review identified 49 PRO measures; the EORTC QLQ-C30/PAN26 were used most frequently and mapped with interview concepts. Patients found the EORTC QLQ-C30/PAN26 to be understandable and relevant; neuropathic side effects were suggested additions. CONCLUSIONS:This is the first study to develop a conceptual model of patients' experience of metastatic/recurrent pancreatic cancer and explore the content validity of the EORTC QLQ-C30/PAN26 following therapeutic advances. The EORTC QLQ-C30/PAN26 appears conceptually relevant; additional items to assess neuropathic side effects are recommended. A recall period should be stated throughout to standardise responses.

Project description:BackgroundAbemaciclib is a CDK4/6 inhibitor used to treat hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer. The prognostic value of patient-reported outcomes (PROs) has been minimally explored for treatment outcomes with CDK4/6 inhibitors. The performance of PROs compared with Eastern Cooperative Oncology Group performance status (ECOG-PS) is unknown.Materials and methodsThis study pooled data from single-arm trial, MONARCH 1, and randomized trials, MONARCH 2 and 3. In total, 900 patients initiated abemaciclib and 384 comparator therapy. Pretreatment PRO association with progression-free survival (PFS) was modeled using Cox proportional hazards regression. Prediction performance was assessed via the C-statistic (c). PROs were recorded via the European Organisation for Research and Treatment of Cancer QLQ-C30.ResultsPatient-reported physical function, pain, role function, fatigue, and appetite loss were associated with PFS on univariable and adjusted analysis (p < .05). Physical function (c = 0.55) was most predictive, superior to ECOG-PS (c = 0.54), with multivariable analysis indicating both provide independent information (p < .02). In the pooled randomized arms of MONARCH 2 and 3, the PFS treatment benefit (hazard ratio [95% confidence interval]) of abemaciclib (vs. comparators) was 0.75 (0.57-1.0) for low physical function, compared with 0.48 (0.40-0.59) for intermediate/high (p[interaction] = .01).ConclusionPROs were identified as prognostic factors for PFS in patients initiating abemaciclib, with patient-reported physical function containing independent predictive information beyond ECOG-PS. Low physical function was associated with a decrease in the magnitude of PFS benefit from abemaciclib. PROs should be explored as prognostic, predictive, and stratification factors for clinical use and research trials of CDK4/6 inhibitors.Implications for practiceFor the first time, pretreatment patient-reported outcomes have been shown to be independent prognostic markers for progression-free survival (PFS) in patients diagnosed with hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced breast cancer treated with abemaciclib. Importantly, patients with low physical function had a smaller PFS benefit from abemaciclib (vs. comparator) than patients with intermediate/high physical function. The present study demonstrates patient-reported outcomes as a simple, effective, inexpensive, and independent prognostic marker for patients with HR+/HER2- advanced breast cancer treated with abemaciclib.

Project description:BackgroundThe prognostic value of patient-reported outcomes (PROs) has been minimally explored in advanced breast cancer (BC), and their comparative prognostic performance against Eastern Cooperative Oncology Group performance status (ECOG PS) is largely unknown.Patients and methodsThis study pooled individual participant data from clinical trials CLEOPATRA, EMILIA, and MARIANNE. Pre-treatment PRO associations with overall survival (OS), progression-free survival (PFS), and grade ≥3 adverse events were evaluated via Cox proportional hazards regression. Prognostic performance was assessed with the C-statistic (c). PRO values were collected via the Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire. All analyses were stratified by study and treatment arms. Analyses adjusted for known prognostic variables were conducted. Exploratory analysis of the prognostic performance of PROs compared to ECOG PS was undertaken.ResultsThe study included data from 2894 patients initiated on contemporary therapies including pertuzumab (n = 765), trastuzumab (n = 1173), trastuzumab emtansine (n = 1225), taxanes (n = 1173), lapatinib (n = 496), and capecitabine (n = 496). On univariable and adjusted analysis, patient-reported physical well-being, functional well-being, and BC subscale were all identified to be associated with OS, PFS, and grade ≥3 adverse events (P < 0.05). Patient-reported physical well-being was the most prognostic PRO for all assessed outcomes. The OS prognostic performance of physical well-being (c = 0.58) was superior to ECOG PS (c = 0.56) (P < 0.05), with multivariable analysis indicating that both provide independent information (P < 0.0001).ConclusionsPROs were identified as independent prognostic factors for OS, PFS, and grade ≥3 adverse events in patients with human epidermal growth factor receptor 2 (HER2)-positive advanced BC initiating contemporary treatment options. Further, patient-reported physical well-being was more prognostic of OS than ECOG PS and contained independent information. PROs have value as prognostic and stratification factors for clinical use and research trials of anticancer treatment in HER2-positive ABC.

Project description:We previously reported clinical outcomes and physician-reported toxicity of gemcitabine and hypofractionated stereotactic body radiation therapy (SBRT) in locally advanced pancreatic cancer (LAPC). Here we prospectively investigate the impact of gemcitabine and SBRT on patient-reported quality of life (QoL).Forty-nine LAPC patients received 33 Gy SBRT (6.6 Gy daily fractions) upfront or after ≤3 doses of gemcitabine (1000 mg/m2) followed by gemcitabine until progression. European Organization for Research and Treatment of Cancer QoL core cancer (QLQ-C30) and pancreatic cancer-specific (European Organization for Research and Treatment of Cancer QLQ-PAN26) questionnaires were administered to patients pre-SBRT and at 4 to 6 weeks (first follow-up [1FUP]) and 4 months (2FUP) post-SBRT. Changes in QoL scores were deemed clinically relevant if median changes were at least 5 points in magnitude.Forty-three (88%) patients completed pre-SBRT questionnaires. Of these, 88% and 51% completed questionnaires at 1FUP and 2FUP, respectively. There was no change in global QoL from pre-SBRT to 1FUP (P = .17) or 2FUP (P > .99). Statistical and clinical improvements in pancreatic pain (P = .001) and body image (P = .007) were observed from pre-SBRT to 1FUP. Patients with 1FUP and 2FUP questionnaires reported statistically and clinically improved body image (P = .016) by 4 months. Although pancreatic pain initially demonstrated statistical and clinical improvement (P = .020), scores returned to enrollment levels by 2FUP (P = .486). A statistical and clinical decline in role functioning (P = .002) was observed in patients at 2FUP.Global QoL scores are not reduced with gemcitabine and SBRT. In this exploratory analysis, patients experience clinically relevant short-term improvements in pancreatic cancer-specific symptoms. Previously demonstrated acceptable clinical outcomes combined with these favorable QoL data indicate that SBRT can be easily integrated with other systemic therapies and may be a potential standard of care option in patients with LAPC.

Project description:PURPOSE:For older women with breast cancer, local therapy options may include lumpectomy plus whole-breast irradiation (Lump + WBI), lumpectomy plus brachytherapy (Lump + Brachy), lumpectomy alone (Lump alone), mastectomy without radiation therapy (Mast alone), and mastectomy plus radiation therapy (Mast + RT). We surveyed a population-based cohort of older breast cancer survivors to assess the association of local therapy with long-term quality-of-life outcomes. METHODS AND MATERIALS:We used nationally comprehensive Medicare claims to identify women aged ?67 years in whom nonmetastatic breast cancer was diagnosed in 2009, who were treated with 1 of the 5 aforementioned treatment options, and who were still alive in 2015. From this cohort, 1650 patients (330 patients per treatment) were randomly selected. A survey that included the CanSORT (Cancer Surveillance and Outcomes Research Team) Satisfaction with Breast Cosmetic Outcome, BREAST-Q, Decisional Regret Scale, and EQ-5D-3L was mailed to potential participants. We used multivariable linear regression to assess associations between local therapy and outcomes after adjusting for patient, disease, and treatment covariates. RESULTS:Among the 489 women who returned the surveys (30% response rate), the median age at diagnosis was 72 years (range, 67-87 years). The interval from diagnosis to survey completion was approximately 6 years for all patients. Compared with Lump + WBI (adjusted score, 3.40), the CanSORT cosmetic satisfaction scores were higher for Lump + Brachy (score, 3.77; P = .007) and Lump alone (score, 3.80; P = .04) and lower for Mast + RT (score, 3.01; P = .006). Similar trends were seen for BREAST-Q cosmetic satisfaction. BREAST-Q psychosocial, sexual, and physical well-being and EQ-5D-3L global health status tended to be better in patients treated with less irradiation and less surgery. BREAST-Q adverse radiation effects were worse for Lump + WBI compared with Lump + Brachy. Decisional regret regarding surgery and radiation therapy did not differ across groups. Compared with patients treated with Lump + WBI, patients treated with Lump + Brachy and Lump alone reported slightly higher rates of in-breast recurrence (excess risk of 5.8% and 6.4%, respectively; P = .01). CONCLUSIONS:In this nationally diverse cohort, less irradiation and less surgery were associated with better long-term quality-of-life outcomes. However, patient regret regarding surgery and radiation therapy was similar across all groups.
