Health-related quality of life trajectories among older breast cancer survivors: a SEER-MHOS analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAs the survival of breast cancer patients continues to improve, health-related quality of life (HRQOL) becomes an important concern in survivorship. However, there is a lack of knowledge regarding long-term changes in HRQOL after diagnosis among older breast cancer survivors. This study examined HRQOL trajectories over 10 years after diagnosis.
methodsOlder women diagnosed with breast cancer at age ≥ 65 years in 1998-2017 in the SEER-MHOS database were eligible. These women must have participated in the surveys at least once within 24 months before diagnosis and at least twice within 10 years after diagnosis. HRQOL was measured using the SF-36/VR-12 questionnaire and summarized as physical (PCS) and mental component summary (MCS) scores. Latent class growth analysis was conducted to identify PCS and MCS trajectory groups. Exploratory descriptive analysis was conducted to characterize these groups.
resultsA total of 580 women met the eligibility criteria. There were three classes of PCS trajectory, with all showing declining over time with differing starting points: high-declining (35.5%), mid-declining (41.2%), and low-declining (23.3%). Two classes of MCS trajectory were identified with, all showing a maintaining trend: high-stable (72.3%) and low-recovering (27.7%). The individuals in a worse trajectory group were characterized by older age at diagnosis, higher body mass index, lower education, more comorbidities, more difficulty completing activities, and poor health perception at pre-diagnosis.
conclusionOlder women showed declining PCS trajectories after breast cancer diagnosis while maintaining their MCS scores. These results suggest that more active and early interventions are needed to improve HRQOL deterioration in older breast cancer survivors, by incorporating comprehensive geriatric assessment and multidisciplinary geriatric oncology services.
