Abstract
Locally advanced head and neck squamous cell carcinoma (LA-HNSCC) is characterized by high rate of recurrence, resulting in a poor survival. Standard treatments are associated with significant toxicities that impact the patient's quality of life, highlighting the urgent need for novel therapies to improve patient outcomes. On this regard, noble metal nanoparticles (NPs) are emerging as promising agents as both drug carriers and radiosensitizers. On the other hand, co-treatments based on NPs are still at the preclinical stage because of the associated metal-persistence.In this bioconvergence study, we introduce a novel strategy to exploit tumour chorioallantoic membrane models (CAMs) in radio-investigations within clinical equipment and evaluate the performance of non-persistent nanoarchitectures (NAs) in combination with radiotherapy with respect to the standard concurrent chemoradiotherapy for the treatment of HPV-negative HNSCCs. A comparable effect has been observed between the tested approaches, suggesting NAs as a potential platinum-free agent in concurrent chemoradiotherapy for HNSCCs. On a broader basis, our bioconvergence approach provides an advance for the translation of Pt-free radiosensitizer to the clinical practice, positively shifting the therapeutic vs. side effects equilibrium for the management of HNSCCs.

Abstract
With the rapid approval of immune checkpoint inhibitors for lung, melanoma, breast, genitourinary, and hematological malignancies, the hematopoietic cells in the tumor microenvironment (TME) are now considered an important, if not essential, consideration for cancer scientists. In many instances, syngeneic murine models have not been highly predictive for responsiveness in clinical trials. Our limited understanding of the human TME have, therefore, precluded a rational translation of immunotherapeutic combinations. This has led to the adoption of hematopoietic humanized murine models for the study of human tumor immunology in vivo. However, concerns about chimerism rates, HLA mismatching, and incomplete reconstitution of the innate immune system have driven a quest for improvements in these allogeneic humanized murine systems. Presented in this article is a completely autologous xenotransplantation method for reconstituting the human tumor immune microenvironment in vivo without the use of a patient's peripheral blood which is known to be associated with low engraftment rates. With this new approach, the current limitations of allogeneic humanized models are avoided by using matched bone marrow cells (BMCs) and derived tumor xenoplants (PDXs) from solid tumors in cancer patients. This autologous system provides a platform for studying endogenous lymphocytic and myeloid cell infiltration into the human tumor in vivo. © 2020 Wiley Periodicals LLC.

Abstract
Correlative studies from checkpoint inhibitor trials have indicated that better understanding of human leukocytic trafficking into the human tumor microenvironment can expedite the translation of future immune-oncologic agents. In order to directly characterize signaling pathways that can regulate human leukocytic trafficking into the tumor, we have developed a completely autologous xenotransplantation method to reconstitute the human tumor immune microenvironment in vivo. We were able to genetically mark the engrafted CD34+ bone marrow cells as well as the tumor cells, and follow the endogenous leukocytic infiltration into the autologous tumor. To investigate human tumor intrinsic factors that can potentially regulate the immune cells in our system, we silenced STAT3 signaling in the tumor compartment. As expected, STAT3 signaling suppression in the tumor compartment in these autologously reconstituted humanized mice showed increased tumor infiltrating lymphocytes and reduction of arginase-1 in the stroma, which were associated with slower tumor growth rate. We also used this novel system to characterize human myeloid suppressor cells as well as to screen novel agents that can alter endogenous leukocytic infiltration into the tumor. Taken together, we present a valuable method to study individualized human tumor microenvironments in vivo without confounding allogeneic responses.
