Filter by:This is an open-label, multicenter, multiple-ascending dose, FIH, Phase 1 study of RTX-321 for the treatment of patients that are HLA-A*02:01 positive with persistent, recurrent, or metastatic, unresectable, HPV 16+ cancers.
This phase II trial studies how well sacral nerve stimulation works in treating low anterior resection syndrome or fecal incontinence (the body's passage of stool without control) in patients with rectal cancer that has spread to nearby tissues or lymph nodes, or other pelvic cancer. Sacral nerve stimulation is a permanent implant that may improve bowel functions by stimulating the nerves that control the muscles related to bowel function.
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
Registry participants with advanced malignancy or myelodysplasia will have a sample of their tumor or tissue analysed for genetic alterations using next generation sequencing (NGS) performed in a lab that has been certified to meet a high quality standard. Treatments and outcomes will be reported to the registry to allow further understanding of how genetic differences can lead to better diagnosis and treatments.
Local excision for early rectal cancer has proven its feasibility and oncological safety. Indeed, lymph node invasion does not exceed 1% and 10% in pT1sm1 and pT1sm2 rectal carcinomas respectively. Two procedures are currently performed in these early cancers as well as in preneoplastic lesions. Transanal endoscopic microsurgery (TEM), which has proven its superiority over traditional transanal excision, is a surgical approach associated with a 92% R0 excision rate, a survival comparable to radical anterior resection and a low morbidity. It consists of a full-thickness excision. The second procedure is a recently introduced technique: the endoscopic submucosal dissection (ESD), which encompasses only the mucosa and submucosa. ESD enables endoscopists to achieve higher en bloc resection rates than standard mucosectomy and is associated with a 88% R0 resection rate, which decreases to 65% in the subgroup of European series. Though very promising, the role of ESD remains controversial in malignant lesions with few published reports. There are therefore 2 different techniques with 2 different dissections (full-thickness vs. submucosal) to achieve the same oncological treatment. So far, only one retrospective single-center study including 63 patients has compared TEM and ESD in early rectal cancer without finding any difference between the 2 procedures, and there are no other available studies comparing TEM and ESD for any type of colorectal tumor. The aim of the present research is to compare ESD with TEM for early rectal cancer and rectal adenomas for short- and long-term outcomes.
Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide. Infection by certain high-risk oncogenic types of HPV (HR-HPV) is the major cause of several cancers in men, notably squamous cell carcinoma (SCC) of the anal canal. Rates of anal infection with these HR-HPV strains and the resultant high-grade anal dysplasia and anal cancer are much higher in men who have sex with men (MSM) than in the general population. Co-infection with human immunodeficiency virus (HIV) further amplifies this burden, making the rates of anal SCC in HIV-positive MSM higher than the historic rates of cervical cancer prior to the adoption of routine cervical cytology screening. Despite these alarming statistics, there are no established protocols for optimal screening and treatment of anal HPV and cancer precursors, nor has there been any widespread rollout of organized screening programs anywhere in Canada. Further, not only does HPV directly cause significant disease in these men, but there is growing epidemiologic evidence that HPV infection may enhance sexual transmission of HIV. These significant knowledge gaps translate into fundamental deficiencies in care for HIV-positive MSM. The HPV Screening and Vaccine Evaluation in MSM (HPV-SAVE) study team will recruit a large group of MSM from various Ontario and Vancouver clinics, in order to carry out a number of different studies. The HPV-SAVE team brings together community and internationally-recognized experts in HPV and HIV disease and mucosal immunology, to better define the optimal approaches for primary and secondary prevention and treatment of HPV-associated anal disease among HIV-positive MSM, and to explore biological mechanistic evidence regarding the potential role of HPV as a co-factor for HIV transmission. This will yield critical information which can lead to improvement in the health of MSM, and will provide a foundation on which to build further, large-scale screening and treatment trials on a national level. The primary aim of the current study is to systematically compare ablative therapy versus intensive observation alone (also known as 'watchful waiting') in outcomes relating to high-grade anal dysplasia.
Patients with locally advanced rectal and esophageal carcinomas typically undergo neoadjuvant chemoradiation therapy prior to surgical resection. While response rates to this treatment differ among these three cancers, generally 20-25% of patients exhibit minimal or no response to preoperative chemoradiation therapy while 20-30% exhibit a complete pathologic response, and the remainder receiving a partial response. This will be a multi-center study of patients with newly diagnosed rectal adenocarcinoma, or anal squamous cell carcinoma (SCC) who will undergo neoadjuvant chemoradiation prior to surgery. The tumor from these patients will be tested to determine whether response to neoadjuvant chemoradiation can be accurately predicted.
There is increasing evidence of a role of EGFR, treatment with EGFR-inhibitors in anal cancer and synergies of EGFR-inhibitors with radiotherapy. Addition of the human anti-EGFR antibody Panitumumab to chemoradiotherapy seems therefore solidly justified. This trial investigates concurrent panitumumab/capecitabine/mitomycin concurrent to IMRT-radiotherapy. Treatment components used in this study have been selected on scientific rationale. The trial regimen should be feasible with acceptable toxicity and outcome similar to historic series.
The main purpose of this study is to study the safety and effectiveness of ADXS11-001 when combined with standard chemotherapy and radiation treatment for anal cancer. ADXS11-001 is an investigational agent that is not approved by the FDA to treat anal cancer or any other cancer.
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.
