Filter by:Cervical cancer is the most frequent neoplasm and the third in mortality rate of the malignancies in women in the world. It results in about 200,000 women dying of cervical cancer each year worldwide. The available forms of treatment - surgery, radiation therapy, and chemotherapy - are all cytoreductive treatment modalities, so, in addition to killing cancerous cells, healthy cells are also destroyed in the process. Indeed, there is a need to decrease the incidence of cervical cancer and develop better forms for its treatment. Human papillomaviruses (HPV) have been consistently implicated in causing cervical cancer especially those high-risk types (HPV 16, 18, 31, 45) which have been strongly associated with cervical cancer. HPV 16 was found in more than 50% of cervical cancer tissues. So, the host immune response plays an important role in determining the regression of a cervical abnormality or persistence and progression to a malignancy via targeting HPV. The ideal cancer treatment should be able to eradicate systemic tumors at multiple sites in the body while having the specificity to discriminate between neoplastic and nonneoplastic cells. In this regard, antigen-specific cancer immunotherapy represents an attractive approach for cancer treatment. By cooperating with Dr. TC Wu at the Johns Hopkins Medical Institutes, the investigators have recently developed some E7-specific cancer vaccines of different strategies such as DNA, or replication-defective SINrep5 virus. They found that these E7-chimeric DNA vaccines are capable of preventing and treating the growth of murine model tumors expressing E7. These positive results from the preclinical murine models have encouraged the investigators to focus on the development of a cancer vaccine and immunotherapy and apply these vaccines to human subjects. However, it is very important to set up various E7-specific immunologic assays of human beings to evaluate the effects of a cancer vaccine or immunotherapy in future clinical trials. So the investigators would like to provide this proposal to address the development of HPV 16 E7-specific immunologic assays in human beings. There are two main goals in this study. First, the investigators would like to establish and compare the differences of HPV type 16 E7-specific immunologic responses between the normal population, people with HPV infection, patients with cervical intraepithelial neoplastic (CIN) lesions, and patients with cervical cancer. Second, they would like to correlate the disease severity of cervical cancer with the immunologic responses to HPV type 16 E7 antigen.
Cervical cancer is the most frequent neoplasm of women in Taiwan and in the world. It influences about 2,700 women with about 1,000 women dying of cervical cancer each year and in Taiwan. Human papillomaviruses (HPV) have been consistently implicated in causing cervical cancer especially those high-risk types which have been strongly associated with cervical cancer. In recent years, there has been compelling evidence that infection with human papillomavirus (HPV) is a major etiologic factor in the development of cervical intraepithelial neoplasia (CIN) and cervical carcinoma. As in most virus-induced diseases, an adequate immune response is likely to play a key role in the clearance of HPV infections and HPV-related lesions. This assumption is born out by both epidemiological studies and animal models. Immune-compromised patients such as HIV-infected women, organ transplant recipients, and patients suffering from other forms of malignancies, are at a higher risk of developing CIN lesions and invasive cervical cancer. Moreover, several studies establish the existence of natural HPV E7-specific cytotoxic T lymphocyte (CTL) immunity in humans. Only a minority of women infected with oncogenic HPV types develop CIN or cervical cancer. Indeed, the majority of CIN lesions do not progress or even regress to normal cytology, indicating that other factors such as an inadequate immune function are necessary for the development of progressive CIN lesions and cervical carcinoma. Consequently, the HLA class I and II phenotypes may be correlated with an effective immune response against HPV-associated cervical lesions. Differences in the recognition of foreign antigens, such as those contributed by alleles at the HLA class I or II loci, might be proposed to affect the risk of developing cervical cancer. In the present proposal, the investigators would like to examine the HLA class I and II associations among Taiwanese women with cervical neoplasia. The purposes of this proposal are: 1. to address the relationships between the HLA class I and II haplotype, HPV infection, and cervical cancer; and 2. to elucidate the immunologic responses to HPV type 16 in different HLA class I and II haplotypes. It will help the investigators to identify which population of HLA genotypes is more susceptible to HPV infection and progresses to invasive cervical cancer. The results of this research will be very useful for the prevention and screening of cervical cancer in the future.
This is a phase I/II study to evaluate the safety and toxicity of celecoxib in combination with standard concurrent cisplatin and radiotherapy in women with locally advanced cervix cancer. In addition, we aim to determine the effect of celecoxib (Celebrex) on tumour oxygenation, interstitial fluid pressure, COX-2 levels, prostaglandin E2 levels, angiogenesis and apoptosis.
The objective of this study is to determinate whether the adding of FDG-PET is helpful in the treatment of advanced cervical cancer with concurrent chemoradiation.
RATIONALE: Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Sometimes when chemotherapy is given, it does not stop the growth of tumor cells. The tumor is said to be resistant to chemotherapy. Giving isotretinoin and interferon alpha-2b together with paclitaxel may reduce drug resistance and allow the tumor cells to be killed. PURPOSE: This phase II trial is studying how well giving isotretinoin and interferon alpha-2b together with paclitaxel works in treating patients with stage IV, recurrent, or persistent cervical cancer.
Investigator has since decided not to pursue this protocol further. No patients were enrolled. This study is to determine the maximum tolerated dose of external beam radiation to the para-aortic lymph nodes using intensity modulated radiation therapy (IMRT). This protocol will test the hypothesis that the use of IMRT and amifostine will decrease GI toxicity and therefore allow the radiation dose to the para-aortic lymph nodes to be safely escalated.
The purpose of the study is to evaluate the efficacy and safety of Irinotecan plus cisplatin as first-line chemotherapy for advanced or recurrent cervical cancer
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer form forming, growing, or coming back. Vaccines may help the body build an effective immune response against human papillomavirus and may be effective in preventing cervical intraepithelial neoplasia or cervical cancer. It is not yet known whether human papillomavirus vaccine is more effective than hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer. PURPOSE: This randomized phase III trial is studying human papillomavirus vaccine to see how well it works compared to hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer in younger healthy participants.
Objective: To explore the hypothesis that different methods of selecting and printing information for cancer patients could improve emotional support by affecting interaction with others, and so lead to improved psychological wellbeing. Design: Randomised trial with 8 groups (three factors, 2X2X2). Data collected at recruitment and three month follow-up. Participants: 400 patients starting radiotherapy and their 'confidant' (the person in who they confide). Interventions: Printed booklets. 1. Half had 'general' CancerBACUP information for that cancer; half had 'personal' information from the medical record plus selected general information; 2. Half chose information by 'interacting' with the computer; half had a larger volume of material in booklets that were produced 'automatically'. 3. Half had additional 'anxiety management advice'. Outcomes: Patients' views; use of booklet with others; change in reported social support; change in anxiety and depression.
Patients with more advanced stages of cervix cancer are treated by radiotherapy. Overall, more than 50% are cured. Approximately half of those patients not cured have current cancer in the irradiated volume. Higher doses of radiation would be expected to cure more patients. To give high doses of radiation safely, the investigators need to know very precisely where the cancer is and then they can use new technology available at the Cross Cancer Institute (tomotherapy) to target the cancer precisely, giving higher doses to the cancerous tissues and lower doses to the non-cancerous tissues. This study of ten patients with cervical cancer will investigate the added value of MRI scanning on precise tumor definition to facilitate more accurate radiotherapy treatment planning. For this study, patients will be treated in the conventional way with conventional doses. The investigators hope that treatment for future patients will be planned with MRI data and that they will be treated to higher doses of tomotherapy.
