Regressor tumors (P91 and UV-5C25), known to express potent tumor-specific transplantation antigens, were briskly rejected when transplanted either sc or ip into syngeneic mice (DBA/2 and BALB/c, respectively). These tumors demonstrated markedly different behavior following transplantation into the anterior chamber of syngeneic mice. Tumors grew to significant masses and survived for prolonged periods within the anterior chamber of the eye. The extended growth and survival of regressor tumors in the anterior chamber (i.e. immune privilege) were abrogated by splenectomy and thus resemble anterior chamber-associated immune deviation. However, this immune privilege proved to be temporary and was superseded by complete tumor resolution. Studies of mice immunosuppressed with UV light or X-ray irradiation demonstrated that spontaneous intraocular resolution of regressor tumors was due to specific systemic immunity that not only led to intraocular tumor resolution but also prevented the spread of the primary intraocular tumor to distant organs and rendered the hosts highly resistant to secondary challenge with sc tumor inocula. The present findings were relevant to understanding human retinoblastoma, in intraocular neoplasm demonstrating a high incidence of spontaneous resolution, and will hopefully form a foundation for designing immunotherapeutic strategies for treating human intraocular neoplasms.
