View clinical trials related to Anal Cancer.
Filter by:Treatment of anal cancer has been always linked to quality of life. Recently, with development on radiotherapy technique, toxicities have been lowered with the maintenance of adequate rates of disease control. This trial intends to follow patients prospectively with questionnaires to evaluate sexual quality of life among patients who are who men who have sex with other men and have been subject to concurrent chemoradiotherapy with IMRT technique.
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
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.
Prospective, open-label, within-subject, multi-center pilot study of Lymphoseek in the detection of lymph nodes in subjects with known squamous cell carcinoma of the anus.
The purpose of this study is to maximize patient involvement in the treatment of anal cancer. Specifically, the investigators will investigate whether patients wish to take part in the decision making on radiation dose and whether they want a high or low radiation dose.
Anal canal cancer is a relatively rare disease, representing 1.2% of digestive cancers and 6% of anorectal cancers. Incidence is less than 1/100 000 of the general population. However, the incidence has increased considerably over the past three decades. The main risk factors are HPV infections and smoking. Initial treatment comprises radiochemotherapy or radiotherapy alone, according to the patient's tumor stage and tolerance of chemotherapy. The choice of the most appropriate treatment strategy will condition the patient's prognosis. Consequently, early assessment of the initial extension of the tumor, its therapeutic response and relapses constitute determining factors in the management of the disease Despite the good results obtained, persistent disease is observed in 30% of cases and abdominal-pelvic salvage amputation can then prove effective in cases of local or loco-regional relapse. The great majority of relapses occur within 2 years after treatment. Reported prognostic survival factors are the T stage, size inferior or superior to 4 cm and inguinal or pelvic lymph node involvement. The rules for follow-up are not substantiated by high levels of proof. Follow-up focuses principally on the clinical examination although the type and frequency of the paraclinical examinations are not backed by any consensus.
In this study, participants with multiple types of advanced (unresectable and/or metastatic) solid tumors who have progressed on standard of care therapy will be treated with pembrolizumab (MK-3475).
A national study of a three year cohort consisting of all patients diagnosed with anal cancer in 2011- 2013 with data retrieval from three national registries: Cancer Registry, Patient registry and Cause of Death Registry all within the Swedish Board of Health and Welfare. All out- and inpatient visits with diagnoses, admission dates and discharge dates will be requested including. Patient documentation from the concerned hospitals will be collected and data on the details of the treatment collected retrospectively in a standardised fashion using a clinical record form. Comorbidity will be calculated using data from the Patient Registry using all main and co-diagnoses 2 years prior and then at least two years after treatment cessation. Detailed questionnaires will be sent out once at 2-3 years and a second time at about 6 years after index treatment.
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.
This randomized pilot trial studies how well two supportive programs work for improving fatigue and depressive symptoms in patients with GI undergoing chemotherapy. Possible mediators such as psychological stress, circadian disruption, and inflammation, will also be explored.
