Active clinical trials for "Anus Neoplasms"

This phase I clinical trial is studying the side effects and the best dose of vorinostat when given together with paclitaxel and carboplatin in treating patients with metastatic or recurrent solid tumors and human immunodeficiency virus (HIV) infection. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with paclitaxel and carboplatin may kill more tumor cells. NOTE: An administrative decision was made by NCI to halt further study of vorinostat in this specific patient population as of February 1, 2013. No patients remain on vorinostat. Going forward this study will determine the safety and tolerability of the paclitaxel and carboplatin combination in this patient population.

RATIONALE: Drugs used in chemotherapy, such as mitomycin, fluorouracil, and cisplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known whether radiation therapy and mitomycin are more effective when combined with fluorouracil or with cisplatin in treating anal cancer . PURPOSE: This randomized phase II/III trial is studying how well giving radiation therapy and mitomycin together with fluorouracil works compared to radiation therapy, mitomycin, and cisplatin in treating patients with locally advanced anal cancer.

This study evaluates the use of ABI-1968, a topical cream, in the treatment of anal precancerous lesions in adults with and without human immunodeficiency virus (HIV) infection

There is increasing awareness of augmenting risk of anal cancer in people living with HIV, especially among men who have sex with men (MSM). High resolution anoscopy (HRA) represents the gold standard to detect pre-cancerous anal high-grade squamous intraepithelial lesions (HSIL), however, the procedure is time-consuming, costly and, most importantly, the learning curve is very flat. This yields a poor implementation of anal screening and, likely, to an excess of otherwise preventable anal cancer. Other screening methods include digital ano-rectal examination, anal-rectal cytology and human papillomavirus (HPV) genotyping, since infection with high-risk HPV genotypes has been identified as the main reason for the development of HSIL. To date, there is no consensus in screening strategies. Furthermore, it remains unclear whether, in whom and to which extend the currently available topic and invasive treatment options for HSIL should be applied, given that the natural history of the development of anal cancer remains poorly understood. The present cohort study aims to provide real-life data on the screening, management and follow-up of HIV-infected MSM is warranted for a better understanding of anal cancer in this setting.

This study investigates if circulating tumor DNA can improve the detection of early treatment failure or recurrence in localized squamous cell carcinoma of the anus (SCCA) after curative chemoradiotherapy thereby increasing the potential for cure. This will be done by comparing the standard follow-up program with ctDNA guided imaging follow-up. Secondly, the aim is to establish early interventions against late morbidities.

This phase II trial studies the side effects of LET-IMPT and standard chemotherapy, and how well they work in treating patients with newly diagnosed stage I-III anal canal squamous cell cancer. LET-IMPT is a type of radiation therapy that uses high energy proton "beamlets" to "paint" the radiation dose into the target and may help to kill tumor cells and shrink tumors. Giving LET-IMPT and standard chemotherapy may work better in treating patients with anal canal squamous cell cancer.

Background: In the United States, each year there are more than 30,000 cases of human papillomavirus (HPV) associated cancers. Some of these cancers are often incurable and are not improved by standard therapies. Researchers want to see if a new drug M7824, which targets and blocks a pathway that prevents the immune system from effectively fighting the cancer can shrink tumors in people with some HPV cancers. Objectives: To see if the drug M7824 causes tumors to shrink. Eligibility: Adults age 18 and older who have a cancer associated with HPV infection. Design: Participants will be screened with medical history and physical exam. They will review their symptoms and how they perform normal activities. They will have body scans. They will give blood and urine samples. They will have a sample of their tumor tissue taken if one is not available. Participants will have an electrocardiogram to evaluate their heart. Then they will get the study drug through a thin tube in an arm vein. Participants will get the drug every 2 weeks for 26 times (1 year). This is 1 course. After the course, participants will be monitored but will not take the study drug. If their condition gets worse, they will start another course with the drug. This process can be repeated as many times as needed. Treatment will stop if the participant has bad side effects or the drug stops working. Throughout the study, participants will repeat some or all the screening tests. After participants stop taking the drug, they will have a follow-up visit and repeat some screening tests. They will get periodic follow-up phone calls.

This is a Phase 1, multiple dose, ascending dose escalation study to define a MTD/RD and regimen of XmAb20717, to describe safety and tolerability, to assess PK and immunogenicity, and to preliminarily assess anti-tumor activity of XmAb20717 in subjects with selected advanced solid tumors.

RATIONALE: Infrared coagulation may be effective in preventing the development of anal cancer in patients who have anal neoplasia. PURPOSE: Pilot study to evaluate the effectiveness of infrared coagulation in preventing anal cancer in HIV-positive patients who have high-grade anal neoplasia.

RATIONALE: Interleukin-12 may kill tumor cells by stimulating a person's white blood cells to kill cancer cells. PURPOSE: Phase I trial to study the effectiveness of interleukin-12 in treating patients with cancer in the abdomen.
