Time toxicity in breast cancer care: a nationwide cross-sectional survey of multidimensional time burden in Japan.
Article in Breast cancer (Tokyo, Japan), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTime toxicity has increasingly been recognized as an important dimension of cancer care alongside traditional clinical outcomes such as survival and toxicity. Although breast cancer therapy has become increasingly individualized, limited evidence exists regarding time toxicity beyond hospital-based care. This study aimed to quantify and characterize time toxicity in patients with breast cancer in Japan.
methodsA nationwide cross-sectional web-based survey of female patients was conducted in Japan. Among 866 respondents, the analysis focused on 598 patients with breast cancer. The survey assessed care-related time, non-care time, family caregiving time, information-seeking time, subjective distress associated with time burden, and activity restrictions.
resultsThe median waiting time for outpatient consultations was 60 min. The median hospital stay per visit was 240 min for chemotherapy and 40 min for radiotherapy. Overall, 69.1% of patients perceived hospital stay as "long" and 67.8% as "distressing." Patients required a median of 10 days of rest during peak treatment-related symptom burden and an additional 15 min per outing for appearance-related care. Participants reported that family members spent a median of 25.5 h per month providing caregiving support. Patients also reported substantial time spent seeking information after diagnosis and forgoing work, travel, and exercise.
conclusionsTime toxicity in breast cancer care extends beyond hospital visits to include substantial non-care time and family caregiving time. Recognizing time toxicity as a potentially modifiable dimension of treatment burden may help inform treatment planning, supportive care, and shared decision-making in breast cancer care.
