  • Patent number: 11339219
    Abstract: Blockade of immune checkpoints such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death-1 (PD-1) shows promise in patients with cancer. Inhibitory antibodies directed at these receptors have been shown to break immune tolerance and promote anti-tumor immunity. These agents work particularly well in patients with a certain category of tumor. Such tumors may be particularly susceptible to treatment because of the multitude of neoantigens which they produce.

  • Patent number: 11286531
    Abstract: A diagnostic test for ovarian cysts is based on the detection of mutations characteristic of the most common neoplasms giving rise to these lesions. With this test, tumor-specific mutations were detected in the cyst fluids of 19 of 24 (79%) borderline tumors and 28 of 31 (90%) malignant ovarian cancers. In contrast, we detected no mutations in the cyst fluids from 10 non-neoplastic cysts and 12 benign tumors. When categorized by the need for exploratory surgery (i.e., presence of a borderline tumor or malignant cancer), the sensitivity of this test was 85% and the specificity was 100%. These tests could inform the diagnosis of ovarian cysts and improve the clinical management of the large number of women with these lesions.

  • Patent number: 11268153
    Abstract: We queried DNA from saliva or plasma of 93 HNSCC patients, searching for somatic mutations or human papillomavirus genes, collectively referred to as tumor DNA. When both plasma and saliva were tested, tumor DNA was detected in 96% (95% CI, 84% to 99%) of 47 patients. The fractions of patients with detectable tumor DNA in early- and late-stage disease were 100% (n=10) and 95% (n=37), respectively. Saliva is preferentially enriched for tumor DNA from the oral cavity, whereas plasma is preferentially enriched for tumor DNA from the other sites. Tumor DNA in the saliva and plasma is a valuable biomarker for detection of HNSCC.

  • Patent number: 11254988
    Abstract: We determined the sequence of ATRX and DAXX in 447 cancers from various sites. We found mutations most commonly in pediatric glioblastoma multiformae (GBM) (11.1%), adult GBM (6.5%), oligodendrogliomas (7.7%) and medulloblastomas (1.5%); and showed that Alternative Lengthening of Telomeres (ALT), a telomerase-independent telomere maintenance mechanism found in cancers that have not activated telomerase, perfectly correlated with somatic mutations of either gene. In contrast, neuroblastomas, and adenocarcinomas of the ovary, breast, and pancreas were negative for mutations in ATRX and DAXX. Alterations in ATRX or DAXX define a specific molecular pathway that is closely associated with an alternative telomere maintenance function in human cancers.

  • Publication number: 20210374962
    Abstract: A scoring functions is developed and used for identifying patients who might be responsive to a PD-1 axis directed therapy. The scoring functions are obtained by extracting features from multiplex-stained sections, selecting features that correlate with response to the therapy using a feature selection function, and fitting one or more of the selected features to a plurality of candidate scoring functions. A candidate scoring function showing the desired balance between predictive sensitivity and specificity may then selected for incorporation into a scoring system that includes at least an image analysis system.

  • Patent number: 11035023
    Abstract: A method of recovering metals from electronic waste comprises providing a powder comprising electronic waste in at least a first reactor and a second reactor and providing an electrolyte comprising at least ferric ions in an electrochemical cell in fluid communication with the first reactor and the second reactor. The method further includes contacting the powders within the first reactor and the second reactor with the electrolyte to dissolve at least one base metal from each reactor into the electrolyte and reduce at least some of the ferric ions to ferrous ions. The ferrous ions are oxidized at an anode of the electrochemical cell to regenerate the ferric ions. The powder within the second reactor comprises a higher weight percent of the at least one base metal than the powder in the first reactor. Additional methods of recovering metals from electronic waste are also described, as well as an apparatus of recovering metals from electronic waste.

  • Publication number: 20210172025
    Abstract: Clinical management of human cancer is dependent on the accurate monitoring of residual and recurrent tumors. We have developed a method, called personalized analysis of rearranged ends (PARE), which can identify translocations in solid tumors. Analysis of four colorectal and two breast cancers revealed an average of nine rearranged sequences (range 4 to 15) per tumor. Polymerase chain reaction with primers spanning the breakpoints were able to detect mutant DNA molecules present at levels lower than 0.001% and readily identified mutated circulating DNA in patient plasma samples. This approach provides an exquisitely sensitive and broadly applicable approach for the development of personalized biomarkers to enhance the clinical management of cancer patients.
