Gene Therapy Follow up Protocol for Subjects Previously Enrolled in NCI Center for Immuno-Oncology Studies

Background: Gene therapy is closely followed by the U.S. Food and Drug Administration (FDA). The FDA requires researchers to conduct long-term follow-up of people who have had the treatment. This study collects data on people who have had gene therapy and sends it to the FDA. The data does not include participants names. Objective: To contact current or past participants of gene therapy protocols at least once a year for up to 15 years to ensure they have not had any harmful side effects. Eligibility: People aged 18 and older who have had gene therapy in a National Cancer Institute study Design: Participants will give their address and telephone number. They will also give and the address and phone number of 1 or 2 other people who will know where they are. For the first year after gene therapy, participants will give blood samples 3 times (at 3, 6, and 12 months). For the next 4 years, they may have a physical exam and laboratory tests with a home physician. They will get a kit to mail in blood samples. Or they can visit the NIH Clinical Center. They will be asked if they have had any signs of neurological, autoimmune, or blood disorders, or any new cancers. For years 6 to 15, participants will be contacted yearly via phone or email and asked questions about their health. They may give blood samples. When the participant dies, if researchers think the death was caused by gene therapy, they will ask the participant s family to allow an autopsy.

Conservative Management of HSIL in Patients With Future Pregnancy Aspiration

Conservative management of high-grade squamous intraepithelial lesions (HSILs) seems safe and justified in young women (\<30 years), but evidence is insufficient on whether it is also advisable for older women. This study will be conducted to analyze spontaneous HSIL regression rates in women of reproductive age and establish whether conservative HSIL management could be safely recommended to women of childbearing potential, irrespective of age. This is a single-center prospective observational study that will include consecutive women of reproductive age, referred to a tertiary hospital due to HSIL between March 2021 and December 2025, who prefer conservative management rather than immediate cervical conization. All patients will be followed-up regularly with colposcopy, cytology, human papillomavirus (HPV) testing and biopsies. In case their lesions progress or HSIL persists after 24 months of follow-up, conization will be indicated. Rates of spontaneous regression or resolution, as well as progression rates, will be assessed. Furthermore, the association between potential predictive factors and HSIL resolution will be analyzed.
