Background therapy |
Despite the recent advancements in diagnosis and management of solid malignancies, pancreatic ductal adenocarcinoma (PDAC) remains a highly lethal disease, with mortality to incidence ratio of nearly one and 5-year survival of 6% (1). Only 10-20% of patients with PDAC present with potentially resectable disease while the remaining either present with locally advanced unresectable (40-50%) or metastatic disease (40%) (2). Management of Locally advanced Pancreatic Cancer (LAPC) remains largely under-researched with lack of evidence both in terms of optimal treatment approach and biomarkers that could inform such an approach (3). Although previously conducted studies failed to demonstrate any definite survival advantage of chemo-radiotherapy (CRT) over chemotherapy (CT) alone (4, 5), retrospective analysis of 4 phase II-III studies demonstrated that patients without disease progression after 3 months of CT, followed by CRT had a longer survival than those continuing on CT alone (6). Moreover, a pooled meta-analysis of SAKK and UK studies showed survival advantage with gemcitabine and capecitabine (GEM-CAP) combination (HR 0.86, 95% CI 0.75-0.98, p=0.02) (7, 8); suggesting this could be considered as useful neo-adjuvant chemotherapy (NACT) approach. Recent evidence suggests that addition of epidermal growth factor receptor (EGFR) inhibition to CRT is feasible and promising in terms of efficacy (9). Furthermore, EGFR is known to be expressed or upregulated in up to 69-95% of advanced pancreatic cancer (10, 11) and the EGFR tyrosine kinase inhibitor (TKI), erlotinib combined with gemcitabine demonstrated modest survival benefit over gemcitabine alone (12). However, currently there are no convincing data on the combination of TKI and radiotherapy, whilst cetuximab, an anti-EGFR antibody has been safely combined with chemotherapy and radiotherapy in patients with LAPC and with other cancers (13-15). | ||

Emergent data from the LAP-07 study failed to demonstrate any meaningful survival advantage (either progression free survival or overall survival) with the use of chemo-radiotherapy following first-line chemotherapy in locally advanced pancreatic cancer. These results were presented at the ASCO 2013 annual meeting and thus the study was closed on recommendation of IDMC. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
The study closed prematurely resulting in recruitment of only 17 patients, therefore data obtained from the study need to be interprested with caution. The molceular data obtained form the study on utility of micro-RNA21 is however extremely valuable | |||
