Abstract 2559

Background

The APACT trial compared disease-free survival in pts with surgically resected PA randomized to nab-P+GEM or GEM as adjuvant regimens. We compared the QoL impact of both regimens in the biggest cohort of pts (n = 379/arm) in which QoL was studied in this setting.

Methods

The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and pancreatic cancer module (PAN26) scores were assessed in 12-week intervals at screening (BL), middle and end of treatment (EOT), and up to 2.5 years of follow-up (FU). A mixed model for repeated measures analysis adjusting for BL score was conducted to predict scores by arm at each visit. Time until definite deterioration (TUDD) and improvement (TUDI) were compared between arms, separately during treatment and FU, using a minimal important difference (MID) threshold of 10-points for all QLQ-C30 scales and scale-specific thresholds for PAN26.

Results

The proportion of pts with QoL data at EOT, year 1, and year 3 were 88%, 51%, and 17%, with similar attrition in both arms. The predicted differences between arms for global health (GH) and all but 1 subscale of the QLQ C-30 never reached the predefined MID threshold (Table). nab-P+GEM pts had meaningfully worse predicted scores than GEM pts on 6 of 17 PAN26 scales during treatment, but these differences persisted for only 2 scales at 2 FU visits. For TUDD and TUDI, nab-P+GEM pts deteriorated faster during treatment, but TUDD did not differ for domain-specific or GH scales between arms at FU, during which nab-P+GEM pts improved faster on some scales, including GH.Table:

Conclusions

As expected, nab-P+GEM is associated with temporary reductions in some QoL dimensions vs GEM alone. Over the long term, QoL was not compromised by adding nab-P to GEM as adjuvant therapy for surviving and reporting pts.
