Volpe was also given responsibility for overseeing Canada's investigation of a controversial vitamin-hormone cancer treatment run by Luigi di Bella in Italy. Some of Di Bella's supporters believed that his treatments actually cured cancer, and requested that their government investigate the possibility of assisting his research. Volpe led a delegation of Canadian doctors to Italy, arguing that they would either expose Di Bella as a fraud or establish the terms for assistance: they concluded there was no evidence to support the validity of his work. Volpe initially recommended that further research be conducted, arguing the doctor's treatment could lead to an improved quality of life for cancer patients even if it did not actually cure the disease.
