RESUMEN
BACKGROUND: Recent studies have shown adjuvant therapy improves outcomes from pancreatic cancer (PC). This study investigates receipt and timing of PC treatments, and association with outcomes. METHODS: The analysis cohort consisted of patients with newly-diagnosed PC at a single institution over 5 years. Primary Endpoints were (i) receipt of recommended therapy, and (ii) overall survival (OS). RESULTS: Among 102 patients, 52 underwent resection. Out of 36 localized resected and 16 locally advanced resected (LAR) patients, 26 and 13, respectively, received adjuvant therapy. Six of the latter group received neoadjuvant therapy. Median OS for resected patients was 15.7 months (range 0.6-51.4), compared with 7.7 for unresected patients (range 0.4-32.0) (P < 0.001), and 14.0 months for patients with resection alone (range 0.6-24.4) vs. 16.1 for patients who also received adjuvant therapy (range 3.2-51.4) (P= 0.027). Out of 46 patients undergoing up-front resection, 33 had R0 surgical margins. For the six LAR patients undergoing neoadjuvant therapy, all margins were R0. CONCLUSION: After resection, a substantial proportion of patients do not receive adjuvant therapy, and have worse survival. In this study, neoadjuvant treatment increased both the proportion of patients receiving all components of recommended therapy and the R0 resection rate.

A 62-year-old woman with a pre-existing psoriasis was treated with oral imatinib (400 mg/day) for a metastatic gastrointestinal stromal tumour. Within 4 weeks of starting therapy, she developed a guttate psoriasis flare. The eruption markedly improved within 2 weeks following cessation of imatinib. However, it recurred when imatinib was recommenced. She has been able to continue on imatinib (400 mg/day) with low-dose oral methotrexate (12.5 mg/week) controlling the psoriasis.
