Published: June 2022

Abstract
Background: The state of Arizona has a diverse population, with the Latino (31.7%) and American Indian/Alaskan Natives (AI/AN) (5.3%) populations higher than the national average of 18.5% and 1.3%, respectively. The colorectal cancer (CRC) screening rates among Latinos is 54.8% and AI/AN is 35%, compared to the overall Arizona screening rate of 62.6%, potentially contributing to higher CRC mortality rates in these groups.
Objective: Utilizing an inflatable colon to measuring CRC knowledge and intent to screen among Arizona’s diverse populations by administering a pre/post test.
Methods: An inflatable colon with signs in both English and Spanish describes the progression of CRC. Spanish-speaking health educators and culturally tailored flip charts geared toward the AI/AN population are utilized at community events throughout Arizona. Survey distribution measured pre- and post-CRC knowledge and intent to screen following a walking tour of the inflatable colon. Additional efforts include the production of a virtual tour of the giant colon in English and Spanish as an educational tool easily accessible on the UArizona Cancer Center YouTube page.
Results: Convenience sampling is utilized, and participants are recruited at outreach events where the inflatable colon is set up (n=15). Preliminary findings show that individuals increased their knowledge about CRC (76.9% vs 100%), understanding the pathology of CRC (i.e., colon polyp, normal colon tissue vs. cancerous tissue, etc.) (53.8% vs 100%), and CRC screening recommendations (30.8% vs 91.7%).
Conclusions: Colorectal cancer education is reaching diverse populations in Arizona. CRC education is delivered in both English and Spanish, and additional CRC educational tools such as the culturally tailored colon health flipbook for AI/AN population are utilize. The use of the inflatable colon has increased CRC knowledge, CRC pathology, and CRC screening options.

Abstract
Background: Use of vitamin D and calcium-containing supplements are associated with a decreased risk of breast cancer among women in the general population. Whether this association exists among women at a high-risk due to a BRCA1 or BRCA2 mutation is not known. Thus, we conducted a case-control study to evaluate the association between vitamin D and/or calcium supplement use and the risk of breast cancer among BRCA mutation carriers.
Methods: BRCA mutation carriers enrolled in a longitudinal study, that collected information on cancer history and lifestyle factors, were invited to complete a supplemental questionnaire on past supplement use. Vitamin D and calcium supplement use were categorized as never or ever use. Total average daily vitamin D and calcium use was stratified as never, moderate, or high intake based on tertiles. Unconditional logistic regression was used to estimate the odds ratio (OR) and 95% confidence intervals (CI) of invasive breast cancer associated with supplement use. Analyses were stratified by BRCA mutation type and menopausal status at breast cancer diagnosis.
Results: This study included 134 cases and 276 controls. Compared to never users, ever vitamin D or calcium-containing supplement use was associated with decreased odds of breast cancer (OR=0.54; 95%CI 0.31, 0.91; P=0.02 for vitamin D; OR=0.61; 95%CI 0.36, 1.05; P=0.07 for calcium). The protective effect of vitamin D and calcium was stronger for those with the highest intake of each supplement (OR=0.44; 95% CI 0.22, 0.89; P=0.02 for vitamin D; OR=0.55; 95% CI 0.28, 1.08; P=0.08 for calcium), compared to never use. For vitamin D use, findings were significant among premenopausal women while for calcium use, the inverse associations were stronger among postmenopausal women. Findings were also significant for BRCA1 mutation carriers only, however, stratified analyses were limited by small strata.
Conclusions: Although based on a relatively small sample, our findings suggest a potential protective effect of vitamin D and calcium-containing supplement use for breast cancer among high-risk women. Future studies with larger samples and prospective study design are warranted.

Abstract
Background: The survived cancer cells after cytotoxic chemotherapy are known to promote immune evasion phenotype by increasing the expression of PD-L1 and CD47. Targeting of CD47 and PD-L1 is predicted to overcome immune evasion by coordinately restoring each innate and adaptive immunity. IOH-001, a CD47/PD-L1 dual-targeting bispecific antibody, has been shown to activate immune cells in tumor microenvironment by blocking PD-1/PD-L1 signals that inhibit cytotoxic T-cells, while also blocking interaction with CD47/SIRPa between cancer cells and macrophages. We have investigated whether IOH-001 inhibits tumor growth via co-targeting tumor cells or not.
Methods: To assess the function of IOH-001, a series of in vitro functional assays including cell surface binding, antibody-dependent cellular cytotoxicity (ADCC), phagocytosis assays and mixed lymphocyte reaction (MLR) assay were performed compared with the parent antibody. In vivo efficacy of IOH-001 was tested in colon cancer mouse models with human genes KI.
Results: IOH-001 has been shown to be bound strongly to various types of PD-L1/CD47-expressing cancer cells including the ones in solid and hematological cancers. In most cancer cells, IOH-001 was demonstrated to have a lower EC50 than the parental antibodies and to be bound in a dose-dependent manner as well. Interestingly, IOH-001 also has shown the selectivity to bind only to cancer cells even under the conditions of co-culturing RBC and cancer cells. IOH-001 has induced phagocytosis of cancer cells by human blood CD14+ monocyte-derived macrophages. Since IOH-001 is an IgG1 type antibody, ADCC and IFN-r expression have been increased compared with the parental antibodies. Consistent with the in vitro data, IOH-001 has more strongly suppressed tumor growth than the combination treatment of the parental antibodies in a dose-dependent manner in syngeneic animal models. Moreover, the tumor of the CR mouse has been identified not to be re-generated in the re-challenge model.
Conclusion: IOH-001, dual-blockage of anti-CD47 and anti-PD-L1, has shown the benefits in treating some solid tumors. Bispecific antibody IOH-001 is more likely to work better in targeting tumor cells than the combination of anti-CD47 and anti-PD-L1. Preclinical efficacy results of IOH-001 provide a strong rationale for assessing therapeutic potential in clinical studies.

Published: June 2022

Abstract
Background: Bleeding is one of the most commonly observed clinical signs of gastrointestinal cancer. Coagulation regulates inflammation and angiogenesis in cancer, and is associated with tumor development and metastasis. To date, there has been no measures to quantify the state of intra-tumoral coagulation. We hypothesized that intra-tumoral coagulation as quantified using coagulation score is associated with angiogenesis and worse prognosis in gastric cancer.
Methods: The coagulation score was determined by the Gene set variation analysis (GSVA) algorithm as GSVA score of the “HALLMARK_COAGULATION” in the MSigDB hallmark gene sets collection. Transcriptome data of 807 gastric cancer patients of TCGA_STAD and GSE84437 cohorts were used for the analysis.
Results: We found that high coagulation score was significantly associated with high AJCC T-category (p = 0.018), lymph node metastasis status (p = 0.036), AJCC stage (p = 0.006) in the TCGA cohort. The association of the score with staging were validated by GSE84437 cohort. Further, patients with high score were associated with worse disease-specific survival and overall survival (OS) (p = 0.019 and 0.011, respectively) in the TCGA cohort, and OS in GSE84437 cohort (p = 0.012). Although the coagulation score was not associated with cell proliferation-related nor immune-related signaling, gastric cancer with high coagulation score highly enriched epithelial mesenchymal transition (EMT), myogenesis, apical junction, transforming growth factor (TGF)-β signaling, and angiogenesis consistently in both cohorts (all false discovery rate&lt;0.25). The coagulation score strongly correlated with angiogenesis score, and high coagulation was significantly associated with high infiltration of angiogenesis-related vascular cells, including endothelial cells, microvascular endothelial cells, lymphatic endothelial cells, and pericytes, calculated by xCell algorithm, as well as high expression of angiogenesis-related genes, including Endothelial cell marker, and vascular stability related genes.
Conclusion: Intra-tumoral coagulation assessed by coagulation score is associated with clinical outcomes of gastric cancer patients.

Abstract 5970: Tumor vessel normalization by a novel anti-TIE2 antibody PMC-403 enhances the effectiveness of radiation therapy on cancer therapy

Published: June 2022

Abstract
Purpose: The delivery of drugs and immune cells into the tumor microenvironment is limited due to abnormal tumor vessel which is characterized as low oxygen concentration, low perfusion rate and leakage. It leads to diminish the efficacy radiation therapy. Traditional anti-angiogenesis strategies attempt to reduce the tumor vascular supply, but their success is restricted by insufficient efficacy or development of resistance. To solve the problem, we try to using PMC-403, which can normalize the abnormal condition of tumor vessel.
Experimental procedures: Target selectivity: It was measured by Surface Plasmon Resonance (SPR) assay. Human TIE2 Cho-K1 cells or mouse TIE2 Cho-K1 cells were tested for species cross-reactive assay based on flow cytometry (FACS).In vitro studies: Human umbilical vein endothelial cells (HUVEC) were used for TIE2 signal pathway analysis with western blot assay and efficacy analysis with VEGF-induced vessel permeability assay.In vivo study: Glioblastoma model mice were employed for the assessment of tumor vessel normalizing activity of 1 mg/mouse PMC-403. CT26 colon cancer model mice were used to evaluate the anti-tumor efficacy of PMC403 (10 mg/kg) in combination with radiation therapy. Hypoxyprobe was used to measure the improvement of hypoxic conditions in tumor tissue.
Summary of data: PMC-403 has a nanomolar range of affinity for both human or mouse TIE2 expressing cells. This contributed to dose-dependent ANG1-like TIE2 and FOXO1 phosphorylation and inhibited VEGF-induced vascular leakage, thereby contributing to ANG1-like vascular normalization. Moreover, similar to ANG-1, p-VEGFR2 and p-VE-Cadherin levels were significantly reduced by PMC-403, suggesting that PMC-403 can normalize blood vessels. In addition, PMC-403 stabilized abnormal tumor blood vessels in the glioblastoma mouse model and significantly reduced tumor growth and tumor hypoxia in the combination treatment (PMC-403 + radiation therapy) compared to radiation therapy alone, although the antitumor effect of PMC-403 alone was not effective in the same condition model.
Conclusions: PMC-403, an anti-TIE2 monoclonal antibody, is a novel tumor vessel stabilizer. PMC-403 improved tumor microenvironment hypoxic condition that synergized with radiotherapy when it combined together for the anticancer therapy. These data strongly support the notion that PMC-403 can effectively treat tumors even with low doses of radiation by stabilizing tumor blood vessels.

Published: June 2022

Abstract
Purpose: Portable hand held confocal laser endomicroscopy is a novel, noninvasive technology that provides real time imaging during biopsy procedure and could be used to perform rapid histopathological diagnosis. However, its ability of determining whether the ex vivo samples obtained during lung cancer surgery or biopsy are tumor or non tumor is yet to be evaluated. Methods: Real time imaging of 75 surgical samples was performed. In preanalytic process, the samples were stained with fluorescent dye. Benign and malignant histologic structures were classified by cell density, nuclear size variability, and nuclear arrangement, which are compared with HE images from the same section.
Results: We defined the confocal laser endomicroscopy atypia classification from the findings of the cells and made a comprehensive atlas of digital biopsy images for pleural surface, bronchus, and lung parenchyma. A total of 3,734 digital images were correlated with 75 frozen lung specimens. Three pathologists assessed digital biopsy images for defining cancer versus non cancer. Overall accuracy was 92.2%, The sensitivity for malignancy was 100% and the specificity was 84.4%. Both inter observer (k = 0.51) and intra observer (k = 0.52) agreement confirmed moderate agreement. Conclusion: Portable confocal laser endomicroscopy was useful to differentiate malignant from benign, to assess the histology of pleural surface and bronchial margin and might be substitute for rapid on site evaluation of pathologic diagnosis during surgical or biopsy procedure.

Published: June 2022

Abstract
Background: The incidence of male breast cancer (MBC) is lower than female breast cancer (FBC), representing 1% of all breast cancer worldwide. The difference with FBC may affect the treatment strategy of MBC, but the necessary precondition is that we should know more about the difference between FBC and MBC. However, Because of its low incidence that the relevant data about MBC is relatively scarce. Here we report some data about gene mutation of MBC, and compared it with FBC.
Methods: Blood or tumor Tissue samples of breast cancer were collected and subjected to NGS in a College of American Pathologists (CAP)-certified and Clinical Laboratory Improvement Amendments (CLIA)-accredited lab for gene mutation analysis (3D Medicines Inc.,Shanghai, China). Statistical analysis was performed using GraphPad Prism (version 7.01) and SPSS version 21.0 (SPSS,Inc.).
Results: Approximately 182 samples were analyzed, among which, exist 82 samples were from primary tissue, 66 samples were breast cancer liver metastases, 20 were lung metastases and 14 were brain metastases. High genomic heterogeneity was found among primary breast cancer tissue, breast cancer liver metastases, lung metastases, brain metastases, that is at least 20 gene mutations were found in these BC samples, while different gene mutations were showed among primary and different metastases tissues. The top five mutated gene in primary tumor tissue were TP53(80.49%), PIK3CA(53.66%), FGF19(30.49%), ERBB2(26.83%), MYC(23.17%); in liver metastases tissues were TP53(54.55%), FGF19(39.39%), PIK3CA(37.88%), ERBB2(21.21%), CCND1(19.70%); in lung metastases tissues were TP53(70.00%), PIK3CA(55.00%), ERBB2,MCL1(25.00%), CDKN2A/2B(20.00%), CCND1, NF1, CDK12(15.00%), CCND2, MYC, PTEN, GNAS, FGF19, PTK2, FGFR1(10.00%); in brain metastases tissues were TP53(42.86%), PIK3CA(28.57%), ZNF703, PREX2, JAK3, MYC, FGFR1(14.29%). Besides, levels of TMB were also different among primary tissue, liver, lung and brain metastases tissues. Higher TMB level were showed in liver and brain metastases tissue than primary and lung metastases tissues (p&lt;0.001).
Conclusions: Different metastases of breast cancer were different in gene mutation landscape, this imply these patients should be managed differently.

Abstract 5986: WAVE2/EGF signaling and miR29 regulates WAVE2 to promote tumor growth and metastasis in triple negative breast cancer

Abstract
Breast cancer is the most frequently diagnosed malignancy in women and is one of the leading causes of death due to cancer invasion, metastasis, and resistance to therapies. Among its variants, triple-negative breast cancer (TNBC) is considered the most aggressive due to its early age of diagnosis, invasive and metastatic properties with poor prognosis. TNBC is a type of breast cancer that lacks expression of the receptors that are commonly found in this type of cancer (estrogen, progesterone, and HER2), which makes it a more difficult target for treatment. Cancer invasiveness and metastasis are known to be promoted by increased cell motility and upregulation of the Wiskott-Aldrich syndrome protein (WASP) and WASP family verprolin-homologous protein (WAVE) - WAVE1, WAVE2, and WAVE3. While the contribution of WAVE2 to cancer progression is well documented, the WAVE2-mediated regulation of TNBC oncogenic properties is still under investigated. In this study, we show that WAVE2 plays a significant role in TNBC development, progression, and metastasis. To investigate this notion, we used CRISPR/Cas9 gene editing to successfully inhibit WAVE2 expression in several TNBC cell lines. In vitro, loss of WAVE2 expression inhibited 3D tumorsphere formation and invasion of TNBC cells. In vivo, in mouse models for TNBC, loss of WAVE2 inhibited tumor growth and metastasis. Mechanistically, we show that the WAVE2-mediated modulation of the oncogenic behavior of TNBC cells is in part due to its phosphorylation downstream of EGF. At the post transcriptional level, we found WAVE2 expression to be regulated by miR29. Together, our findings identify a novel post-translational WAVE2/EGF oncogenic signaling axis, along with a post-transcriptional regulatory axis downstream of miR29, which together regulate the oncogenic activity of WAVE2 in TNBC and open a new therapeutic strategy for the treatment of TNBC.
