Active clinical trials for "Anus Neoplasms"

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.

Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill cancer cells. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Phase I trial to study the effectiveness of interleukin-12 and trastuzumab in treating patients who have cancer that has high levels of HER2/neu and has not responded to previous therapy

PRIMARY: In Phase I, to define a broadly tolerable dose of isotretinoin that can be used in combination with interferon alfa-2a (IFN alfa-2a). In Phase II, to determine trends in efficacy of isotretinoin alone or in combination with IFN alfa-2a as chemoprevention (preventing progression or recurrence) of anal intraepithelial neoplasia ( AIN ) / squamous intraepithelial lesions ( SIL ) in patients with HIV infection. SECONDARY: To evaluate the effects of isotretinoin alone or in combination with IFN alfa-2a on immune function markers, human papillomavirus (HPV) type, and HPV DNA levels. Patients with HIV infection have a significant risk of recurrence following local ablation of intraepithelial neoplasia; thus, anogenital epithelial may become an increasingly important cause of morbidity, and possibly mortality, as the HIV epidemic matures. Clinical studies of non-HIV-infected subjects have established that synthetic retinoids inhibit the progression of epithelial preneoplastic conditions and some neoplastic states.

This research study is studying a targeted therapy as a possible treatment for advanced anal cancer. The following intervention will be involved in this study: -Pembrolizumab

Squamous cell carcinoma of the anal canal (SCCA) is a rare disease and mostly diagnosed at an early stage. After standard concurrent chemoradiation (CRT) with mitomycin (MMC) and 5-fluorouracil (5FU), the disease will recur in 20% of patients. After treatment failure (including salvage surgery), cisplatin-5FU combination is the standard option but complete response is a rare event and the prognosis remains poor with most patients' death occurring in the first 12 months. Decision making for physicians in this setting is only based on retrospective studies or small phase II clinical trials including less than 20 patients. Hence, no efficient standard of care is currently available for relapsing SCCA patients who are currently treated with a palliative intent. Between 2007 and 2013, 8 consecutive patients with advanced recurrent SCCA after CRT were treated with DCF regimen (docetaxel, cisplatin and 5-fluorouracil) in the Regional Cancer Institute of Franche Comté. After a median follow-up of 41 months, 4 patients (50%) achieved a complete response. Three patients underwent surgery of all involved metastatic sites. A pathological complete response was observed for all of them including in metastases occurring in irradiated fields, suggesting that taxane-based chemotherapy might be an effective strategy to circumvent resistance to radiotherapy (a preliminary cohort of 8 patients was published (Kim S et al Annals of oncology 2013). Furthermore, all complete responders were HPV 16, and high levels of specific T cell responses against Human Papillomavirus (HPV) HPV16-derived E6/E7 and telomerase were detected in 50% of complete responders suggesting the potential restoration of cancer immunosurveillance by this regimen. Then, the Epitopes-HPV02 multicenter phase II study will aim to confirm the new role of taxane-based chemotherapy in SCCA patients.

Chemoradiation with 5-FU and Mitomycin C is the standard treatment in anal canal SCC. Panitumumab has shown efficacy in other tumors and anti-EGFR treatment has shown clinical activity in a single report of a refractory anal canal SCC patient. Based on this background, we propose to conduct a phase II study to investigate the efficacy and toxicity of radiotherapy with the association: 5-FU 1000mg/m2 on days 1-4 and 29-32 Mitomycin C 10mg/m2 on days 1 and 29 Panitumumab 6 mg/kg on day 1, then every 2 weeks for 8 weeks

The purpose of this study is to determine whether Alkagin paste is effective at preventing radiodermatitis in patients receiving external beam radiation therapy to the perineal area.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug or combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known whether fluorouracil and mitomycin plus radiation therapy is more effective than fluorouracil and cisplatin plus radiation therapy for anal cancer. PURPOSE: This randomized phase III trial is studying fluorouracil and mitomycin plus radiation therapy to see how well it works compared to fluorouracil and cisplatin plus radiation therapy in treating patients with stage II or stage III anal cancer.

The purpose of this study is to find out if a Chinese herbal cream is effective in treating HSIL (high-grade squamous intraepithelial lesions, also known as HGAIN, or high-grade anal intraepithelial neoplasia).

RATIONALE: Drugs used in chemotherapy, such as irinotecan, fluorouracil, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of irinotecan when given together with fluorouracil and leucovorin in treating patients with advanced gastrointestinal cancer.
