33% -> 10%

The infectious disease doctor brought the empirical statistics.  Using the lock antibiotics therapy, the chance of having the port removed reduces from 33% to 10%.   10% is still higher than what I expected.  It's going to even harder since Lucas will undergo the interim maintenance part of his chemotherapy at the same time and his ANC will be low -- means he will rely solely on the antibiotics to fight off the bacteria infection.
