To optimize treatment, choosing the appropriate relative dose intensity (RDI) of nab-paclitaxel is an important way to improve patient tolerance, therapeutic efficacy, and survival. However, few studies have focused on the efficacy of the RDI of nab-paclitaxel in patients with advanced pancreatic cancer, and whether the RDI of nab-paclitaxel could be employed as an index for treatment remains unknown. To explore the relationship between RDI of nab-paclitaxel and chemotherapy efficacy, survival, quality of life (QoL), and adverse effects in patients with advanced pancreatic cancer.In this retrospective study, a total of 32 patients with advanced pancreatic cancer, ECOG score of 0 to 2 were included from January 2017 to March 2020. The patients were treated with nab-paclitaxel combined with gemcitabine as a first-line treatment and divided into high and low RDI groups. Chemotherapy efficacy, survival, QoL, and adverse effects between two groups were compared.The disease control rate (DCR) was 20.0% in the low RDI group, compared with 81.8% in the high RDI group (P=0.002). A good correlation between nab-paclitaxel RDI and short-term efficacy was observed in all 32 patients (r=0.728, P0.01). Furthermore, the high RDI group had significantly better median overall survival (mOS: 12It is recommended to maintain a sufficient RDI of nab-paclitaxel to ensure that the balance between lerability, therapeutic efficacy, and survival benefits is satisfied in patients with advanced pancreatic cancer. |
