Pala, 24, was named in Richard Agar’s initial 24-man squad but a shoulder injury put paid to his hopes of playing in the tournament.
He has done enough in 2013 to earn a new deal with the Dragons, which includes an option for the 2015 season.
Catalan CEO Christophe Jouffret said: “He is one of the young talents coming through at the club. He went one step further this season and we’re really confident that he will be a great player for our club in the future.”
The centre scored three tries in 12 Super League appearances last season.
