180

Results

Among 201 patients enrolled, 180 were included in the final analysis. Eribulin was administered as first- and second-line chemotherapy to 46 (26.6%) and 70 (47.9%) patients, respectively. Median OS1 and OS2 were 2.25 (95% CI 1.07-2.68) and 1.75 (95% CI, 1.28-2.45) years for first- and second-line eribulin, respectively. Oral 5-FU followed by eribulin had a numerically longer OS1 (2.84 years) than the other sequences.

Baseline Characteristics

Taxane and oral 5-FU were used for 60 (33%) and 57 (32%) patients as frst-line chemotherapy, respectively. For 46 (26%) patients, eribulin was used as frst-line chemotherapy but represented second-line chemotherapy for 70 (48%) patients. The frequent frst- and secondline chemotherapy sequences were as follows: taxane followed by eribulin (n=33), oral 5-FU-based therapy followed by eribulin (n=26), eribulin followed by taxane (n=21), taxane followed by oral 5-FU (n=11), and eribulin followed by oral 5-FU (n=10). Anthracyclines or taxanes were used for 106 patients (58.9%) in the frst- or second-line chemotherapy, whereas neither anthracyclines nor taxanes were used for the remaining 74 patients (41.1%) in both lines.

Participant flow

Overall, 201 patients were enrolled during July 2015 2017. Of them, 21 (10.4%) were excluded from this study, 16patients did not receive first line chemotherapy, 2 withdrew consent, two did not meet the inclusion criteria, and one was registered erroneously. The full analysis set comprised 180 patients who underwent first line chemotherapy.

Adverse events

Patients treated with eribulin or oral 5-FU as frst-line chemotherapy had a signifcantly lower discontinuation rate owing to adverse events than those treated with anthracyclines or taxanes (p=0.038). Additionally, lower toxicity was the main reason eribulin was used as frst- and second-line chemotherapy for patients not previously treated with anthracycline/taxane.

Outcome measures

The primary endpoint was the frstline OS (OS1), defined as the time from the start of firstline chemotherapy to death from any cause. The secondary endpoints were the secondline OS (OS2) and thirdline OS (OS3), which were defined as the time from the start of second and thirdline chemotherapy, respectively. PFS, time to treatment failure (TTF), new metastasis-free survival (nMFS), and safety were evaluated as the secondary endpoints. Moreover, OS1 stratified by two age groups (65 and 65 years) was also evaluated as the exploratory adhoc analysis.
