Mismatch repair deficiency tested in seven cancer types

Sapien is surveying different #tumor types in its #biobank for mismatch repair-deficiency (MMR-D), also called microsatellite instability (MSi-High). This is because #colorectalcancer #patients with MMR-D do not respond well to standard #chemotherapy but do respond to immune checkpoint inhibitors or ICI. To see which other #cancers may benefit from immune checkpoint inhibitors such as #PD1, we tested 500 curated cases of Endometrial, H&N, Kidney, Liver, Gastric and Thyroid cancers and compared them to 165 colorectal cancers by IHC.
We observe that H&N, Liver and Thyroid cancer have low MMR-D. However, Endometrial cancers have 4-5 times higher MMR-D as compared to CRC; Stomach and Renal cancers also have 5-6% MMR-D cases. Our data suggests that immune checkpoint inhibitors may greatly improve the response rate and survival of Endometrial, Stomach and Kidney cancers in addition to CRC.

Our paper is out in Frontiers in Pharmacology

Our paper on first ever reported establishment of a cell culture from a rare brain tumor (DIG glioma), is published in Frontiers in Pharmacology journal, with Impact factor of 4.5. Such primary cultures are very useful for drugdevelopment and phenotypic screening.

Sapien’s samples and real world data enables validation of a new Indian breast cancer test with high concordance to OncotypeDx test

In 2014, Sapien partnered with Oncostem Diagnostics to provide our curated breast cancer FFPE blocks and RWE 5 years treatment and recurrence outcome data to enable the validation of a new test to accurately determine the risk of recurrence in early stage breast ca patients. A key goal of the test was to identify patients at low risk that could avoid chemotherapy and its side-effects, a major benefit to #cancerpatients (see Sapien referenced in this & previous papers).

It’s gratifying to see their first test, canAssist Breast for hormone positive breast cancer patients, perform equivalent to the gold standard Oncotype Dx test, a more expensive and higher TAT for Indian patients.

Our deep collection of matched FFPE blocks and longitudinal RWE data to enable precision medicine tests has continued to grow, both in breast cancer (>10,000 cases), and in #colorectalcancer, #lungcancer, #oralcancer, #kidneycancer, #ovariancancer #glioma #liver cancers.
