Symptom Assessment Following Surgery for Lung Cancer: A Canadian Population-based Retrospective Cohort Study

Electronic Patient-Reported Outcome-Based Symptom Management Versus Usual Care After Lung Cancer Surgery: Long-Term Results of a Multicenter, Randomized, Controlled Trial

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.We previously reported superior symptom control of electronic patient-reported outcome (ePRO)-based symptom management after lung cancer surgery for up to 1 month postdischarge. Here, we present the long-term results (1-12 months) of this multicenter, randomized trial, where patients were assigned 1:1 to receive postoperative ePRO-based symptom management or usual care daily postsurgery, twice weekly postdischarge until 1 month, and at 3, 6, 9, and 12 months postdischarge. Long-term patient-reported outcomes were assessed with MD Anderson Symptom Inventory-Lung Cancer module. Per-protocol analyses were performed with 55 patients in the ePRO group and 57 in the usual care group. At 12 months postdischarge, the ePRO group reported significantly fewer symptom threshold events (any of the five target symptom scored ≥4; median [IQR], 0 [0-0] v 0 [0-1]; P = .040) than the usual care group. From 1 to 12 months postdischarge, the ePRO group consistently reported significantly lower composite scores for physical interference (estimate, -0.86 [95% CI, -1.32 to -0.39]) and affective interference (estimate, -0.70 [95% CI, -1.14 to -0.26]). Early intensive ePRO-based symptom management after lung cancer surgery reduced symptom burden and improved functional status for up to 1 year postdischarge, supporting its integration into standard care.

Patient-Reported Symptom Burden After Cancer Surgery in Older Adults: A Population-Level Analysis

BACKGROUND

Older adults have unique needs for supportive care after surgery. We examined symptom trajectories and factors associated with high symptom burden after cancer surgery in older adults.

PATIENTS AND METHODS

We conducted a population-level study of patients ≥ 70 years old undergoing cancer surgery (2007-2018) using prospectively collected Edmonton Symptom Assessment System (ESAS) scores. The monthly prevalence of moderate to severe symptoms (ESAS ≥ 4) for anxiety, depression, drowsiness, lack of appetite, nausea, pain, shortness of breath, tiredness, and poor wellbeing was computed over 12 months after surgery.

RESULTS

Among 48,748 patients, 234,420 ESAS scores were recorded over 12 months after surgery. Moderate to severe tiredness (57.8%), poor wellbeing (51.9%), and lack of appetite (39.3%) were most common. The proportion of patients with moderate to severe symptoms was stable over the 1 month prior to and 12 months after surgery (< 5% variation for each symptom). There was no clinically significant change (< 5%) in symptom trajectory with the initiation of adjuvant therapy.

CONCLUSIONS

Patient-reported symptom burden was stable for up to 1 year after cancer surgery among older adults. Neither surgery nor adjuvant therapy coincided with a worsening in symptom burden. However, the persistence of symptoms at 1 year may suggest gaps in supportive care for older adults. This information on symptom trajectory and predictors of high symptom burden is important to set appropriate expectations and improve patient counseling, recovery care pathways, and proactive symptom management for older adults after cancer surgery.
