Okay... history lesson here.
Constantinope did not exist until Constantine built it in the 4th century.
Cairo was not founded until 969 AD. That was 300 years after the muslim conquest so, no. Cairo had little to nothing to do with jesusism. Alexandria was the main city of Roman Egypt which became a Roman province after 31 BC after the Battle of Actium.
As near as we can tell the main centers of early xtianity were Alexandria, Ephesus, and Antioch. It was not until Justinian issued his Pentarchy in 527 ( long after Leo I) that Rome was declared the patriarchy for all of Europe - at that time an area being extensively overrun by hordes of smelly barbarians - while Alexandria, Constantinople, Antioch and Jerusalem were given the East. Presumably this reflects the far greater percentage of people living under Roman, and therefore xtian rule at the time. The date of 527 is important. Just over a century later, Jerusalem, Antioch and Alexandria were overrun by the muslims. Constantinople survived in much reduced status until 1453 at which time Rome became the clear winner by default.
Some "victory."
