You can use query-replace-regexp for this.

Sample input:

This is text. This is text. This is text. This is text. Replace this.
This is text. This is text. This is text. This is text. This is text. Replace
this.
Replace                    this.

M-x query-replace-regexp RET \(replace\)\([ ^I^J]*\)\(this\) RET Done\2that RET

Output:

This is text. This is text. This is text. This is text. Done that.
This is text. This is text. This is text. This is text. This is text. Done
that.
Done                    that.
