The back-row forward suffered a setback this week when he was left out of new England coach Brian Ashton's first squad for the forthcoming Six Nations.
But Sanderson, in a statement released by the club to PA Sport, claimed he is determined to stay at Sixways even if the club lose their top-flight status after three years.
Sanderson said: "I've got no intention of going anywhere. I want to be here for my playing future - irrespective of what happens.
"I love this club and everyone in the dressing room feels the same, and they want to give back the same commitment as they're showing around the rest of the club.
"We feel part of the Premiership and we want to stay here. But one of the things that's fantastic about this club is that no-one here wants to go.
"Because of that commitment to the club, we stand to get something out of it."
Sanderson feels the team spirit being shown by Worcester, despite being bottom of the table, gives them hope of survival ahead of Sunday's clash with London Wasps at Adams Park.
He said: "We've got a huge spirit here. We're a very, very tight team. Generally, in these circumstances, that's extraordinary. A lot of teams would have split apart.
"I'm very proud of the guys. We spend a lot of time together and enjoy each other's company. Those are the qualities that will pull us through.
"We've no influence on whether other teams win or lose, apart from when we play them. It's a huge job.
"We're in a lot of trouble but we're starting to believe that we're capable of getting ourselves out of it.
"We've kept on believing. We've got to put behind us what's happened and look forward to what's coming up."
