Find + delete folders with extension when using variable

we have linux rhel machine 7.2 with the following folders under /kafka/topics

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-1

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-10

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-100

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-103

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-106

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-109

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-112

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-115

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-118

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-121

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-124

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-127

drwxr-xr-x 2 root  kafka    141 May 11 17:19 bgol.ase.fgt.dad3-13

we want to delete all this topics with names - bgol.ase.fgt.dad3 by using variable as ,

topic=bgol.ase.fgt.dad3

find /kafka/topics  -name "$topic*" -exec rm -rf "{}" \;

but I feel the above approach isn't so elegant , since we want to set this approach in bash script

I will appreciate to get other suggestion to delete the folders , when using variable as $topic
