Abstract 2278
Background
Hyperbilirubinaemia is a common disease effect in patients (pts) with metastatic pancreatic cancer (mPC). As clinical trials often exclude them, data on management of these pts are rare. In the framework of a German observational multicenter study (QoliXane), quality of life and therapy data are currently being collected in pts with mPC receiving a combination of nab-paclitaxel and gemcitabine. This is an interim analysis on hyperbilirubinaemia management.
Methods
Pts were included to this analysis if they entered the trial with a bilirubin level ≥ 1.2 mg/dl and completed at least 2 cycles. Bilirubin levels were documented for up to 4 cycles and methods of hyperbilirubinaemia management have been assessed. A both descriptive and explorative analysis was performed using IBM SPSS V 23.
Results
25 of 294 pts (8.5%) were included. Mean bilirubin level was 2.96 mg/dl (range 1.2-12.3) at baseline and dropped considerably by the 2nd cycle to 0.84 (range 0.29-3.9; p = 0.0001). Bilirubin levels decreased in 24 (96%) and increased in 1 (4%) pts upon treatment start. 18 (72%) pts started treatment with standard dosage, 7 (28%) with a reduced regime. 10 (40%) pts underwent additional intervention: either stenting (7 pts, 28%) or bile duct anastomosis (3 pts, 12%). Mean bilirubin values dropped from 4.59 to 1.09 in pts with and from 1.87 to 0.68 in pts without additional intervention. Grade 3/4 toxicity was seen in 60% of pts and most common 3/4 events were anemia, nausea, and fever. Mean Bilirubin Levels1.
| Baseline | Cycle 2 | Cycle 3 | Cycle 4 | |
|---|---|---|---|---|
| All pts (n = 25) | 2.96 | 0.84 | 0.83 | 0.53 |
| no add. intervention (n = 15) | 1.87 | 0.68 | 0.92 | 0.61 |
| any add. intervention (n = 10) | 4.59 | 1.09 | 0.68 | 0.46 |
| add. stenting (n = 7) | 4.52 | 1.19 | 0.84 | 0.35 |
| add. bile duct anastomosis (n = 3) | 4.80 | 0.87 | 0.47 | 0.53 |
| p (all pts)2 | 0.0001 | 0.002 | 0.008 |

Conclusions
Data show that bilirubin levels drop considerably after start of nab-pac/gem therapy. The treatment seems to be feasible, although considerable frequencies of Grade 3/4 toxicities were observed.
