How would you treat an isolated port recurrence of an early stage cervical patient s/p WLE?

A literature search indicates that most port site recurrences are managed fairly aggressively with chemoRT or RT doses 45-66 Gy. This is understandable in the setting of locally advanced or high risk disease, however, for a truly isolated port site recurrence that has been completely resected in a pt with initial early stage disease (i.e. stage IB1, closest margin 1mm), is such aggressive therapy really necessary?
