Abstract: The present disclosure relates to methods of treating or delaying progression of invasive lobular carcinoma (ILC) metastasis in an individual, methods for evaluating, identifying, and/or assessing an individual having an ILC metastasis, as well as methods for genomic profiling of an ILC metastasis.

Abstract: Described herein are methods, devices, and systems for identifying a subset of a plurality of features, using one or more feature importance metrics, for training and using a homologous repair deficiency (HRD) classification model. Further described are methods, devices, and systems for classifying a tumor of a cancer, such as pancreatic cancer, as likely HRD positive or likely HRD negative, and for calling the tumor as HRD positive or HRD negative.

Abstract: Provided herein are methods for detecting a Ewing sarcoma breakpoint region 1 (EWSR1) fusion gene encoding a neoantigen (e.g., in a patient sample), as well as methods of prognosis and treatment related thereto, in some embodiments, the methods further comprise administering a cancer immunotherapy. In some embodiments, the EWSR1 fusion gene is a fusion gene between EWSR1 and WT1, Fill, ERG, FEV, NR4A3, ATF1, CREB1, CREM, CREB3L/CREB3L2, PA7Z1, NFATC2, KLFI5, C11orf93, ZNF444, PBX1, DDIT3, or TFCP2 that encodes a neoantigen.

Abstract: The presently disclosed subject matter provides hydrogel precursor compositions (e.g., solutions) for forming three-dimensional hydrogels that support growth of physiologically relevant tissue when at least one cell is cultured in the three-dimensional hydrogel, kits comprising the hydrogel precursor composition, three-dimensional hydrogels, methods of forming the three-dimensional hydrogels, methods of growing the physiologically relevant tissue using the three-dimensional hydrogels, physiologically relevant tissue grown in the three-dimensional hydrogels, methods of producing hormone-responsive tissue (e.g., milk-producing mammary tissue and related methods of producing milk), methods of screening for candidate agents useful for modulating hormonal responses (e.g., modulating milk production), method of screening for candidate therapeutic agents using the physiologically relevant tissue grown in the three-dimensional hydrogels (e.g., personalized cancer treatments), and related methods of treatment (e.g.
