To investigate that if the serum titer of anti-HPV16 antibody could be a prognostic factor in the cervical cancer patients. C. To investigate the serum titer of anti-HPV16 antibody in HPV16-infected populations with various disease status such as infection only, precancerous lesion, and early and advanced cervical cancer.
RATIONALE: Health education programs and screening methods, such as clinical breast examination and examination of the cervix, may help reduce the number of women who develop breast cancer and cervical cancer. PURPOSE: This randomized clinical trial is studying the early detection of breast cancer and cervical cancer in women in India.
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This clinical trial is evaluating DNA mutations in predicting the effect of external-beam radiation therapy in patients with early breast cancer, localized prostate cancer, or gynecologic cancer.
The purpose of this study is to determine the therapeutic efficacy and complications of systemic consolidation therapy with paclitaxel plus carboplatin following radical hysterectomy and adjuvant chemoradiation for high risk early stage cervical cancer.
The purpose of this study is to determine the therapeutic efficacy and complications of systemic consolidation therapy with paclitaxel plus carboplatin following primary chemoradiation for locally advanced cervical cancer.
RATIONALE: Drugs used in chemotherapy, such as paclitaxel, carboplatin, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving combination chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving paclitaxel together with carboplatin followed by cisplatin and radiation therapy works in treating patients with stage IB, stage II, stage III, or stage IVA cervical cancer.
Point A, the major critical point for dose specification of intracavitary brachytherapy, is defined as the crossing of uterine artery and ureter in treatment of cervical cancer. However, the currently advocated systems use hypothetical point A (HPA) to estimate the dosimetry of brachytherapy. This study is to localize anatomic point A (APA) of cervical cancer patients for reference of radiotherapy. We will use laparoscopic clipping technique to localize APA for cervical cancer patients during pelvic and paraaortic lymph node sampling. When these patients are receiving brachytherapy, orthogonal radiographs will be obtained after insertion of tandem and colpostats by using Henschke afterloading applicators.
In cervical cancer prognosis factors are size of the tumour, pelvic and para-aortic lymph nodes involvement. The initial treatment taking is determined by lymph node evaluation. Early stage cervical cancers at their very beginning, with no lymph node involvement, will be treated either by surgery only or by radiotherapy only, or by both at the same time. At advanced stages, from proximal IB to IIB with bad prognosis (tumour larger than 4 cm and pelvic lymph node involvement), as well as for cancers up to distal stages IIB, III and IVA, treatment relies on radio-chemotherapy, either alone or pre-surgery. The pre-therapeutic complete examination of the cervical cancer includes a clinical examination and a pelvic MRI in order to look for pelvic and para-aortic lymph nodes and to precise the volume and the spreading of the tumour in the pelvic area. A meta-analysis estimating the interest of the MRI showed a variable sensitivity and a specificity for the detection of such lymph node metastasis with a sensitivity varying from 24 to 75 % and a specificity between 84 and 100 % according to the studies. As for the use of an 18-FDG PET scan to detect lymph node involvement, the studies realized so far are performed, usually, on a small number of subjects and with heterogeneous populations. However, it seems that such an examination enables a better detection of lymph nodes than the MRI does, especially for para-aortic lymph nodes depending on the studies, sensitivity varies from 57 to 100 %, and specificity between 92 and 100 %. We propose a prospective, multicentric and multidisciplinary study for the estimation of diagnosis methods. The main aim is to estimate the interest of the 18-FDG PET scan for the detection of pelvic and para-aortic lymph node metastasis in patients with cervical cancer, in comparison with the MRI. This study should enable to include 380 patients within 3 years. An 18-FDG scintigraphy will be performed before any treatment together with an MRI. A comparison between the sensitivity and the specificity of both examinations will be established and a correlation with the histology of the lymph node dissection will be made.
In this study proposal, the investigators will extend their previous studies and examine the kinetic cytotoxic activity with concordant expression of inhibitory natural killer (NK) receptors (iNKR) on activated T cells. The inhibitory role of cytokines will be defined by utilizing the investigators' previously established models of mixed lymphocytes and tumor cells coculture to analyze the expression and activity of cytokines involved in the regulation of iNKRs on cancer-encountered T cells.
Cervical cancer the most frequent neoplasm and the third mortality rate of malignancies of the 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 of its treatment. Human papilloma viruses (HPV) have been consistently implicated in causing cervical cancer especially those high-risk types (HPV 16,18,31,45) 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 cervical abnormality or persistence and progression to 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 represent an attractive approach for cancer treatment. It is now clear that major histocompatibility complex (MHC) class I restricted CD8+ T cytotoxic cells are critical to the generation of antitumor immunity. Cell-mediated responses are critical in anti-tumor immunity. By cooperating with Dr. TC Wu in Johns Hopkins Medical Institutes, we have recently developed some E7-specific cancer vaccines of different strategies such as DNA, or replication-defective SINrep5 virus. We 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 us to focus on the development of 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 being to evaluate the effect of cancer vaccine or immunotherapy in the future clinical trials. So we would like to provide this proposal to address on the development of HPV 16 E7-specific immunologic assays in human being.
