Active clinical trials for "Uterine Cervical Neoplasms"

This is a phase II clinical study of the novel recombinant HPV 16/18 bivalent vaccine expressed in E. coli. The primary purpose of this study is to evaluate which dosage of the HPV vaccine can induce higher antibody and at the same time caused less adverse events. The secondary purpose of this study is to to evaluate the safety and immunopersistence of the study vaccine.

Precancerous lesions of the cervix occur frequently and are treatable. This justifies a population-based screening program. Following an abnormal Pap smear, patients are referred for a colposcopic exam to confirm the presence/stage of disease and select appropriate treatments. Unfortunately, these approaches do not detect all lesions or can sometimes give 'false positive' results (resulting in overtreatment). We are testing a device called a 'multispectral digital colposcope' to determine whether it is more effective at detecting precancerous cervical lesions than existing tools. Success in our study will make diagnoses more accurate and reduce the costs associated with unnecessary treatments.

A research project is currently being undertaken looking at Human Papilloma Virus (HPV) vaccination in special risk groups. It aims to see if young women with a chronic illness respond well to the HPV vaccine or whether they may require additional doses to ensure protective immunity. The four valent HPV vaccine protects against HPV types 16 & 18, cervical cancer and HPV types 6 & 11, anogenital warts. The six special risk groups include: Paediatric Rheumatological Disease Inflammatory Bowel Disease Acute Lymphoblastic Leukaemia Solid Organ Transplant Recipients (kidney and liver) Chronic Renal Disease Bone Marrow Transplants This immunity is measured by antibody levels of the HPV types, which requires a single blood test one month after the final dose of HPV vaccine. This is compared to healthy controls using antibody response to HPV vaccine. This will assess directly whether these special risk groups respond as well to the HPV vaccine.

RATIONALE: Supplements, such as folic acid, may stop or delay the development of cervical cancer in women infected with human papillomavirus. PURPOSE: This phase II trial is studying how well folic acid supplements work in preventing cancer in women infected with human papillomavirus.

The Phenomenon of Tumor Hypoxia Many solid tumors are relatively resistant to treatment with ionizing radiation and certain chemotherapeutic agents such as anthracyclines that are affected adversely by acidic pH. These effects have primarily been attributed to the presence of hypoxic cells within the tumor. The relevance of hypoxia with respect to failure of radiotherapy to cure certain malignancies has had a chequered history. However, in recent years the evidence that hypoxia plays a central role in relative radioresistance has become more compelling. Since approximately two-thirds of all women suffering from cervical carcinoma receive radiation as a component of their therapy, an enhanced understanding of the interactions between hypoxia and radiation as a component of their therapy, an enhanced understanding of the interactions between hypoxia and radiation resistance is critical to improving outcome among those with cervical cancer.

RATIONALE: Studying the barriers that prevent minority and low-income women from undergoing cancer screening, and offering encouragement to them over the telephone, may help improve cancer screening rates. PURPOSE: This randomized phase II trial is studying how well a telephone-based Prevention Care Manager increases screening rates for breast cancer, cervical cancer, and colorectal cancer in minority and low-income women.

RATIONALE: Zinc supplements may lower cadmium levels in smokers and may help prevent DNA damage. PURPOSE: This clinical trial is studying how well zinc supplements work in lowering cadmium levels in smokers.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer or to treat early cancer. SGN-00101 may be effective in preventing the development of cervical cancer in patients who have cervical intraepithelial neoplasia. PURPOSE: This phase II trial is studying how well SGN-00101 immunotherapy works in preventing cervical cancer in patients with grade III cervical intraepithelial neoplasia.

RATIONALE: Chemoprevention therapy is the use of certain substances to try to prevent the development of cancer. Applying topical imiquimod before abnormal cervical cells are removed may be effective in preventing cervical cancer. PURPOSE: Randomized phase II trial to study the effectiveness of applying topical imiquimod before abnormal cervical cells are removed in preventing cervical cancer in patients who have recurrent or persistent cervical neoplasia.

RATIONALE: Imaging procedures such as MRI or CT scans may improve the ability to detect cervical cancer and determine the extent of disease. PURPOSE: Diagnostic trial to determine the effectiveness of MRI and CT scans in evaluating invasive cervical cancer before treatment of patients.
