Delete empty records is now avaliable in Management -> Advanced. Once the item is clicked, it will delete all records with empty patient & tumour information. However, an empty tumour record with a patient will not be deleted consider that an empty tumour will be created when we browse a patient without a tumour.
Locked records cannot be deleted and will throw RecordLockedException.
