Male and Female
1) NAPOLI-1 regimen or S-1 monotherapy is initiated as second-line therapy after failure of gemcitabine=based first-line therapy.
2) Therapy is introduced between September 1, 2019 and February 28, 2021
3) Diagnosis of adenocarcinoma by histological or cytological diagnosis of primary or metastatic lesions.
4) Pancreatic cancer with distant metastasis or recurrent pancreatic cancer by chest CT and abdominal/pelvic contrast-enhanced CT or abdominal/pelvic contrast-enhanced MRI.
In the case of recurrent pancreatic cancer, the following items should be followed:
a) The first treatment regimen after the diagnosis of recurrence is considered as the primary treatment.
b) If postoperative adjuvant chemotherapy was administered, patients are eligible if at least 6 months have elapsed between the last administration of postoperative adjuvant chemotherapy and the recurrence (patients are eligible if the recurrence occurs on the same date 6 months after the last administration of postoperative adjuvant chemotherapy).
c) The first treatment regimen after the diagnosis of recurrence is defined as first-line treatment.
5) Patients must not have used irinotecan (including nanoliposomal irinotecan) or fluoropyrimidines.
6) Patients must be at least 20 years of age at the time of enrollment.

A total of 463 metastatic PC patients were enrolled in this study (257 in the S-1 monotherapy group and 206 in the nal-IRI + 5-FU/LV group). The median OS was 7.50 months (95% CI 4.18-12.69 months) in the nal-IRI + 5-FU/LV group and 5.72 months (95% CI 2.76-10.79 months) in the S-1 monotherapy group. In the IPTW-adjusted Cox proportional hazards model, nal-IRI + 5-FU/LV was associated with a significant OS benefit (pooled IPTW-adjusted hazard ratio, 0.779; 95% CI 0.399-0.941; p = 0.025).

S-1 tended to be given to patients with poor performance status (PS) and moderate or more ascites. In contrast, nal-IRI + 5-FU/LV tended to be given to patients with younger age and liver metastasis. The propensity score distribution between the treatment groups showed covariate imbalance before IPTW adjustment (Supplementary Fig. 1). Standardized mean differences of unadjusted comparisons showed potential imbalances between both treatment groups with respect to many clinical characteristics of interest (e.g., age and Eastern Cooperative Oncology Group PS).
A total of 463 metastatic PC patients were enrolled in this study (206 in the nal-IRI + 5-FU/LV group, and 257 in the S-1 group). The full-cohort data consisted of 463 patients with metastatic PC, whereas the complete-case dataset consisted of 446 patients.
Not applicable.
The main objective of this study was to compare OS using the inverse probability of treatment weighting (IPTW) method in patients treated with nal-IRI + 5-FU/LV and those treated with S-1 monotherapy. The secondary objectives were to compare progression-free survival (PFS) using the IPTW method and tumor response in patients treated with nal-IRI + 5-FU/LV and those treated with S-1.
