This phenomenon is often associated with bacterial, fungal, viral or protozoan infection, or vaccination therapy. 25 Furthermore, PD-L1 expression is enhanced by TNF-α and IL-1β, suggesting that the expression of PD-L1 in tumor cells changes depending on the tumor microenvironment.

Although the mechanism is unclear, the spontaneous regression of cancer is considered to be closely related to antitumor immune responses, such as positive expression of HLA class I and the infiltration of CD8-positive cells. Pancreatic cancer is seldom described as undergoing spontaneous regression, but there are some cases reported in the literature. In renal cell carcinomas spontaneous regression predominate in males by a ratio of 3:1.

Certainly, a misdiagnosis may have been made in the 13th century, but in the 21st century, we have indisputable evidence that spontaneous resolution does sometimes occur. Though we have clearly documented cases of spontaneous regression, it's hard to know how common this phenomenon actually is. Along with misdiagnosis, this is one of the ways in which alternative medicine can seem to cure diseases such as cancer, and … Melanomas, lymphoma, leukaemia, neuroblastoma, renal cell carcinoma, and germ cell cancers have shown higher frequency of SR [81,8].
