Aircraft
The aircraft we were flying was an A321 that had had an odor event the night before resulting in the APU being placed on MEL. We also had that flight's cabin crew deadheading back.Our flight was normal until descending through 14000 ft when a F/A (Flight Attendant) called to tell us that the same odor as the day before was back and a few of the crew and several passengers had noticed it. I told her we would be on the ground soon as by now we were coming up on 10000 ft AGL.I never noticed anything at any time on the flight but I started the Quick Action FUMES checklist. It was 110 degrees with a full flight and no APU so we hustled to [the] gate and shut down the engines. Just then a F/A called requesting an ambulance for a cabin crew member. I had my F/O (First Officer) call ops requesting paramedics to the aircraft. I called Maintenance to let them know of our event and they requested we fill out the Aircraft Smoke Odor Report ASAP which we did.My F/O said he smelled something on final. The F/A's towards the front of the aircraft didn't notice anything but in the aft cabin some crew members and passengers did although only the one crew member requested medical attention and I don't know which one that was. By the time I got out of the cockpit everyone was gone so I never got any more information on our F/A.
A321 Captain reported an event with extreme fumes in the main cabin while in the descent to land.
