DNA Array Analysis of Patients With Cervical Cancer
Summary
Primary Objectives:
1. To obtain preliminary descriptive data on early changes in tumor DNA array expression following chemo-radiation of cervical cancer. These data will permit the design a future studies to correlate array expression changes with clinical outcome.
2. To quantify the degree of therapy-induced apoptosis following chemo-radiation of cervical cancer in order to design future studies to correlate apoptosis levels with clinical outcome.
3. To store material to later correlate the tumor DNA array expression with specific strains of tumor-related human papilloma virus (HPV)
4. To correlate changes in biomarker expression with clinical outcome and findings of the DNA array analyses.
Description
Patients in this study are already scheduled to begin radiation therapy. Researchers will get tumor cells by taking two biopsies of the cervix. The first biopsy of the cervical tumor will be done before any treatment is given.
The second biopsy will be performed about 48 hours after the radiation treatment has begun. They will then study the cells in the lab with a new technique for studying gene expression called DNA array, as well as HPV analysis, quantification of apoptosis levels, hematoxilin and eosin staining, and storage of tissue for future research..
The patterns of gene expression in the biopsies will be compared with the success of radiation treatments.
Some of the material will also be stored and used in the future for other research projects.
This is an investigational study. A total of 18 patients will take part in this study. All will be enrolled at UTMDACC.

Medical and Biotech [MESH] Definitions
Wnt2 Protein
A proto-oncogene protein and member of the Wnt family of proteins. It is frequently up-regulated in human GASTRIC CANCER and is a tumor marker (TUMOR MARKERS, BIOLOGICAL) of gastric and COLORECTAL CANCER.
Mixed Tumor, Mullerian
A tumor, basically a carcinoma with a single sarcoma such as leiomyosarcoma or angiosarcoma or multiple sarcomas of uterine origin. The role of estrogen has been postulated as a possible etiological factor in this tumor. (Holland et al., Cancer Medicine, 3d ed, p1703)
Cancer Vaccines
Vaccines or candidate vaccines designed to prevent or treat cancer. Vaccines are produced using the patient's own whole tumor cells as the source of antigens, or using tumor-specific antigens, often recombinantly produced.
Endodermal Sinus Tumor
An unusual and aggressive tumor of germ-cell origin that reproduces the extraembryonic structures of the early embryo. It is the most common malignant germ cell tumor found in children. It is characterized by a labyrinthine glandular pattern of flat epithelial cells and rounded papillary processes with a central capillary (Schiller-Duval body). The tumor is rarely bilateral. Before the use of combination chemotherapy, the tumor was almost invariably fatal. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1189)
Cervical Plexus
A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.

Vaccine Therapy in Preventing Cervical Cancer in Patients With Cervical Intraepithelial Neoplasia
RATIONALE: Vaccines made from antigens may make the body build an immune response to kill abnormal cervical cells and may be effective in preventing cervical cancer. PURPOSE: Randomized p...
Cetuximab in Treating Patients With Persistent or Recurrent Cervical Cancer
RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help ki...
SU5416 in Treating Patients With Persistent or Recurrent Cervical Cancer
RATIONALE: Biological therapy with drugs such as SU5416 may stop the growth of cervical cancer by stopping blood flow to the tumor. PURPOSE: Phase II trial to study the effectiveness of S...
RATIONALE: Drugs used in chemotherapy, such as cisplatin and tirapazamine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from di...
