Colorectal cancer: a drug in test that destroys the tumor without surgery or chemo

Colorectal cancer: a drug in test that destroys the tumor without surgery or chemo

among all rectal cancerthem adenocarcinomas are the most frequent. To cure them, oncologists usually offer surgery to remove the cancerous area, followed by a chemotherapy. But, for a long time, interleukin 2 and interferon have been the two most…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/3/ b/4/3b4d8dc18b_132423_immunotherapy-syringe.jpg” data-url=”https://news.google.com/health/definitions/medicine-immunotherapy-2725/” data-more=”Read more”>immunotherapy could replace this protocol burdensome for patients. In effect, a small clinical trial made at Memorial Sloane Kettering Cancer Center in New York gave impressive results: 100% of patients were in remissionwithout the need for surgery or chemotherapy, after treatment with a Structure of an antibody

In 100% of patients, the tumor was undetectable at to scanMRI,endoscopy and in biopsies rectal. They did not need surgery or chemotherapy to complete the action of dostarlimab. No patient had a relapse during the follow-up period, which lasted from 6 to 25 months. Dostarlimab did not cause serious side effects in most patients, only rashes, fatigue, nausea, and nausea.

Only one person developed a non-life-threatening thyroid problem.

Dostarlimab also offers hope for people with syndrome of Lynch – eight among the twelve participants in theclinical test. This hereditary disease drastically increases the risk of developing cancer colorectal cancer throughout life, and is associated with poorer outcomes after surgery or cancer chemotherapy. L’immunotherapy could be a promising tool to treat patients affected by Lynch syndrome.

Lasting results?

Dostarlimab is an antibody that prevents recognition of the PD-1 receptor, located on the lymphocytes T, with sound ligand PDL-1, located on cancer cells. The interaction of the receptor with its ligand paralyzes the immune responseinstead of destroying the abnormal cell, the T lymphocyte spares it. By mechanically blocking this interaction, dostarlimab allows T cells to destroy the abnormal cell.

Impressive results that will need to be replicated in future independent clinical trials involving more participants. The question of the sustainability results will also be crucial; if the participants have been in remission for several months, there is nothing to say to date that they will still be in several years.
