Rectal Cancer Disappears After Experimental Use of Immunotherapy. 100% Remission in Clinical Trial

New York, NY...Breakthrough findings were presented at the 2022 ASCO Annual Meeting and published in The New England Journal of Medicine today by researchers at Memorial Sloan Kettering Cancer Center (MSK) confirming a clinical complete response in all 14 patients who received the immunotherapy treatment dostarlimab as a first-line treatment for mismatch repair-deficient (MMRd) locally advanced rectal cancer. This new approach of “immunoablative” therapy uses immunotherapy to replace surgery, chemotherapy and radiation to remove cancer.








MSK’s Andrea Cercek, MD, Section Head of Colorectal Cancer and Co-Director of the Center for Young Onset Colorectal and Gastrointestinal Cancer, and Luis Alberto Diaz, Jr., MD, Head of the Division of Solid Tumor Oncology, led this groundbreaking clinical trial — which saw a 100% complete response rate among its patients. The study also provides a framework for evaluation of highly active therapies in the neoadjuvant setting, where patients are spared from chemoradiation and surgery while treating the tumor when it is most likely to respond.

Study Details and Findings

“Since MMRd colorectal cancer is responsive to PD-1 blockade in the metastatic setting, we hypothesized that locally advanced mismatch repair-deficient rectal cancer is sensitive to checkpoint blockade and may alter the requirements for chemoradiotherapy and surgery, or eliminate the need for additional treatments altogether,” explained Dr. Cercek.

MSK researchers conducted a prospective study in which single agent dostarlimab, an anti-PD-1 monoclonal antibody, was administered every three weeks for six months in patients with mismatch repair-deficient stage 2 and 3 rectal adenocarcinoma, to be followed by standard chemoradiation and surgery. Patients who achieved a clinical complete response were eligible for omission of chemoradiation and surgery.

All 14 who initiated treatment on the trial and have had at least six months of follow-up achieved a clinical complete response with no evidence of tumor on MRI, FDG-PET, endoscopic visualization, digital rectal exam, or biopsy, which satisfied the study’s co-primary endpoint. To date, no patients have required chemoradiation or surgery, and no cases of progression or recurrence have been noted during follow-up (up to 25 months). No serious adverse events were observed. As researchers found the elimination of tumors following six months of therapy with PD-1 blockade, it enabled them to omit both chemoradiation and surgery and to proceed with observation alone.

Treatment Implications

“Surgery and radiation have permanent effects on fertility, sexual health, bowel, and bladder function. The implications for quality of life are substantial, especially in those where standard treatment would impact childbearing potential. As the incidence of rectal cancer is rising in young adults, this approach can have a major impact,” said Dr. Cercek.

“While longer follow-up is needed to assess response duration, this is practice-changing for patients with MMRd locally advanced rectal cancer,” said Dr. Diaz. His early work led to a paradigm shift in treatment for individuals with MMRd tumors in 2017 when the FDA announced the first pan-tumor approval for adult and pediatric patients with metastatic MMRd tumors that progressed following prior treatment. This was the FDA’s first site-agnostic approval. “As we advance our research, we envision PD-1 blockade will be evaluated in other MMRd tumors, including not-yet-metastatic pancreatic, gastric, and prostate cancers in the neoadjuvant setting — which could open the door for a pan-tumor approach akin to MMRd in the metastatic disease.”

"Philadelphia DA Krasner blames mass shooting on 'NRA lobbyists,' ignores own record on illegal gun crime"
DA Krasner blamed lobbyists, but not his dropping charges on convicted felons being caught with guns, using guns when committing crimes, letting convicted felons caught with guns off with no bail.
"Joe Sullivan, the former deputy commissioner of patrol at the Philadelphia Police Department, quickly criticized Krasner for not mentioning anything about more aggressive and focused prosecutions of gun related crimes, especially for repeat violent offenders and convicted felons, while the district attorney instead attacked an advocacy group such as the NRA for legal gun ownership"

Who could ever of thought that not prosecuting violent felons to the full extent of the law or giving those poor, poor violent criminals the minimum sentence would make crime go up?
Just another reason why your typical American says 🖕 Democrats, we're not voting for you and your DEFUND the Police BS and 🖕 for this Economy and 🖕 for the HIGHEST PRICES ON GASOLINE IN HISTORY

    Yet the majority must be atypical.
    The majority say that gun control is a must.
