The purpose of this phase II trial is to determine the feasibility and efficacy of nimotuzumab combined with concurrent chemoradiotherapy for initially inoperable locally advanced cervical squamous cell carcinoma.
The FRDTM is easy to perform and does not require sophisticated laboratory technology and/or experienced pathologists for test result interpretation. Compared to the Pap smear and HPV test, the FRDTM enables clinicians to obtain test results immediately (within 60 seconds) after the screening. This empowers clinicians in making timely decisions on appropriate patient management, and facilitating patient compliance with follow-up procedures. In addition, the FRDTM requires minimal training and technical support. Due to its advantage of rapid visualization of abnormal cervical lesions (CIN2+) in a cost-effective way, health care professionals can make cervical cancer detection accessible to women worldwide, especially in regions with limited medical resources. This is a cross-sectional study to evaluate the clinical performance of Folate Receptor-Mediated Epithelium Staining (FRDTM) in detecting cervical neoplastic lesions (CIN2+).
The purpose of this research is to assess the safety and effectiveness of circumferential radiofrequency ablation (RFA) to the anal canal using the BarrxTM Ablation System to destroy anal high-grade squamous intraepithelial lesions (HSIL). The BarrxTM Ablation System used in this study comprises an RFA generator (Barrx™ FLEX) and the BarrxTM Anorectal Wand. The generator and wand are cleared by the Food and Drug Administration (FDA) for human use and the wand is specifically cleared for treatment of anal intraepithelial neoplasia (AIN). AIN is a precancerous condition. HSIL is an advanced form of AIN. The presence of HSIL has traditionally warranted treatment. RFA has been shown in many studies to effectively and safely destroy precancerous cells in a condition called Barrett's esophagus, which is a precancerous condition of the esophagus (the swallowing tube). Recent studies have shown that RFA may offer the same benefits for those with HSIL in the anal canal. In particular, ablation of the entire circumference of the canal seems to reduce recurrence of HSIL in other locations of the anal canal. This study will last between 12 to 15 months. Subjects will be required to undergo 5 to 8 study visits as outlined below that are carried out by the study doctors or the physician assistant. Most visits will last approximately one hour. Some may be shorter and some may be longer. Up to seventy (70) volunteers will participate in this study at several locations.
This study evaluates the efficacy and safety of the experimental drug, BLS-ILB-E710c, in patients with Cervical Intraepithelial Neoplasia 2/3 (CIN2/3). 2/3 of participants will receive the experimental drug, while 1/3 of participants will receive placebo.
Cervical cancer is the third most frequent neoplasm in Brazilian women (estimated risk of 15.33 cases / 100,000 women by 2014), behind breast and colorectal cancer. This high incidence is explained by the pre-neoplastic lesions of the cervix being probably related to the practice of unsafe sex and to a poor local immune response against HPV. Human papillomavirus (HPV) infection affects people of any age, although it is more common in young people, probably due to increased sexual activity in that period. The association between high-risk HPV and anus neoplasm in men and women with immunodeficiency or immunosuppression has been confirmed and measures related to surveillance are standardized. In patients without immunodeficiencies, this association is still unclear, which may contribute to the lack of adequate standards to diagnose HPV and prevent cancer of the anus. The frequency of the cancer of anus previously considered low, is currently in considerable elevation, mainly squamous cell carcinoma (SCC). The causal relationship between this virus and cancer of the cervix and the anus is established. These facts have motivated the inclusion of this disease as STD, which justifies the necessity of adopting surveillance measures in the clinics of sexual, gynecological and urological diseases. Cancer of the anus, when diagnosed in the early stage, makes healing possible with less aggressive treatments, but in the advanced stage, abdominoperineal amputation is necessary. Concerned about possible anal cancer, some gynecologists have referred patients with genital HPV to search for anal infection.
This is a study to investigate the safety and efficacy of GX-188E administered IM plus local administration of GX-I7 or Imiquimod at cervix in subjects with cervical intraepithelial neoplasia (CIN) 3.
STUDY PURPOSES: This study aims to evaluate a high resolution microendoscope (HRME): 1) To assess the sensitivity and specificity of the HRME device in the detection of cervical intraepithelial neoplasia grade 2 (CIN2) or histologically more severe lesion (NIC2+) and cervical intraepithelial neoplasia grade 3 (CIN3) or histologically more severe lesion (NIC3+) in a comprehensive case-by-case basis; 2) Compare the accuracy of the HRME device with acetic acid visualization (VIA) and colposcopy. METHODOLOGY: 1,780 women with abnormal Pap Smears (ASCUS+) or positive high-risk human papillomavirus (HPV) test in the cervix performed in the Barretos Cancer Hospital (HCB, Barretos, Brazil) screening program will be recruited, either at Mobile Prevention Units or Fixed Units, who have been referred for diagnostic investigation with colposcopy. The invitation for women to participate in the study will be made immediately before the medical consultation for colposcopy, in the Prevention Department of Barretos Cancer Hospital. Women who decide to participate in this study will sign an Informed Consent Form after invitation and relevant explanations, which will be provided by the researcher in charge or by a representative with previous training appointed by him for the application of the Form in question. During the colposcopy examination, the HRME device will be used to check the presence of precursor lesions in the cervix. HRME will capture images from all areas considered abnormal by VIA and/or colposcopy. Any abnormal areas detected by VIA and/or colposcopy will undergo a biopsy. If no abnormal area is observed, a cervical microbiopsy will be obtained from an apparently normal area examined using HRME. If during the study a precursor disease or cervical cancer is detected in any woman, an appropriate treatment will be offered by Barretos Cancer Hospital according to an institutional protocol.
This randomized phase IIB trial studies how well tamoxifen or afimoxifene works in treating patients with estrogen receptor positive breast cancer. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen citrate or afimoxifene may fight breast cancer by blocking the use of estrogen by the tumor cells.
The purpose of this study is to verify the function of p16 hydroxymethylation diagnostic reagents in early diagnosis of oral cancer.
