Abstract 3107

Background

Nasopharyngeal carcinoma (NPC) is a rare cancer in many areas including Europe and Middle East/Mediterranean. Data regarding natural history, prognostic factors and treatment strategies in NPC patients (pts) are derived mostly from studies conducted in endemic regions.

Methods

We collected clinical data on consecutive NPC pts treated in non-endemic countries from 2005 to 2016. Main objective of the study was to collect clinical/biological parameters and to correlate them with the outcome, at uni- and multivariate analysis, using the Cox regression model.

Results

The database included 1220 pts from 34 Centers. They were mainly male (72%), with ECOG performance status (PS) 0 in 74% of the cases, with advanced stages (stage III 42%, IV 33%), and with a median age of 50 years. Tumoral EBER was assessed in 51% (42% positive); plasmatic EBV DNA was evaluated at baseline in 23% of the pts, with a mean value of 12,434 copies/mL (range 0-824,525). Induction, concurrent and adjuvant chemotherapy (CT), were administered to 45%, 83% and 11% of the pts, respectively. Main RT techniques employed were IMRT (81%) and 3DRT (19%). With a median follow up of 56.5 months, 3- and 5-year overall survival (OS) was 83% and 77%, respectively. Among the 411 pts who relapsed, distant metastases were the pattern of failure in 55%, with bone (49%), lung (31%) and liver (29%) as the most represented sites. At relapse, main treatment approach was CT (45%), surgery (24%), re-RT (9%), or supportive care only (10%). At univariate analysis, prognostic factors favorably correlated with OS were: PS (0-1 vs > 1, p < 0.0001); female sex (p = 0.001); global stage (I-II vs III vs IV, p < 0.0001), T stage (T1-T2 vs T3-T4, p < 0.0001), N stage (N0-N1 vs N2-N3, p = 0.0242), baseline plasmatic EBV > 4000 copies/mL (p = 0.0073). At multivariate analysis, all the variables confirmed their prognostic value.

Conclusions

In non-endemic countries, NPC showed survival figures comparable to endemic areas. Stage, PS, gender and plasmatic EBV DNA turned out to be prognostic factors. These data represent the benchmark in non-endemic setting and the referral for building new prospective trials.
