I'd leave them for now and you'll get an extended cropping period. Next Feb cut them back to soil level.
I planted Polka in Feb of last year - we had a fantastic crop and this year the canes have really multiplied - I may need a larger freezer.
They are thirsty plants - I gave mine as much water as my runner beans last summer and it really paid dividends.
I put the sprinkler on mine this last weekend for 20 minutes as we're on light soil and the canes have a lot of leaf which can lose moisture quickly in hot weather.
Enjoy the raspberries - they're really good
