Abstract
The recent development and prospects of cancer immunotherapy have led to diversification of the types of therapeutic agents used. By simultaneously administering various agents, a more effective therapeutic effect can be expected due to the synergistic effects of multiple therapeutics. In particular, if a substance with adjuvanticity and tumor antigen is delivered at the same time, enhanced cancer immunotherapy can be achieved through high cross-presentation and antigen-presenting cell (APC) maturation. To this end, we developed a polymerized phenylboronic acid (pPBA)-based immunogel for the simultaneous delivery of mannan, which has adjuvanticity and tumor antigen. The immunogel was formed by simple mixing of the polysaccharide mannan with pPBA through the formation of phenylboronic ester between the diol of mannose monomers and phenylboronic acids of pPBA. The immunogel was slowly degraded by hydrolysis to release the loaded tumor antigen. In addition, the released mannan played a key role in both APC maturation in vitro and the upregulation of cross-presentation. Finally, the pPBA-mannan immunogel exhibited a significant anticancer effect in the 4 T1 cell-inoculated mouse model, implying the potential of a codelivery system of antigens and adjuvants for effective cancer immunotherapy.

Abstract
BACKGROUND Ribociclib plus fulvestrant demonstrated significant progression-free survival (PFS) and overall survival (OS) benefits in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced breast cancer (ABC). Here we present a new landmark in survival follow-up for a phase III cyclin-dependent kinases 4 and 6 inhibitor clinical trial in patients with ABC (median, 56.3 months). PATIENTS AND METHODS This phase III, randomized, double-blind, placebo-controlled trial was conducted at 174 sites (30 countries). Patients were men and postmenopausal women (age ≥18 years) with histologically/cytologically confirmed HR+/HER2- ABC. Patients could have received ≤1 line of endocrine therapy (ET) but no chemotherapy for ABC. Patients, assigned 2:1, were stratified by the presence/absence of liver/lung metastases and previous ET. Patients received intramuscular fulvestrant (500 mg, day 1 of each 28-day cycle plus day 15 of cycle 1) with oral ribociclib (600 mg/day, 3 weeks on, 1 week off) or placebo. Efficacy analyses were by intention to treat. Safety was assessed in patients receiving ≥1 dose study treatment. OS was a secondary endpoint. MONALEESA-3 is registered with ClinicalTrials.gov (NCT02422615; no longer enrolling). RESULTS Between 18 June 2015 and 10 June 2016, 726 patients were randomly assigned (484, ribociclib; 242, placebo). At data cut-off (30 October 2020), median OS (mOS) was 53.7 months (ribociclib) versus 41.5 months (placebo) [hazard ratio (HR), 0.73; 95% confidence interval (CI) 0.59-0.90]. Subgroup analyses were consistent with overall population. In the first-line setting, most patients in the ribociclib arm (∼60%) lived longer than median follow-up; mOS was 51.8 months in the placebo arm (HR, 0.64; 95% CI 0.46-0.88). In the second-line setting, mOS was 39.7 months (ribociclib) versus 33.7 months (placebo) (HR, 0.78; 95% CI 0.59-1.04). No apparent drug-drug interaction between ribociclib and fulvestrant or new safety signals were observed. CONCLUSIONS This analysis reported extended OS follow-up in MONALEESA-3. mOS was ∼12 months longer in patients with HR+/HER2- ABC treated with ribociclib plus fulvestrant compared with fulvestrant monotherapy.

Abstract
BACKGROUND AND PURPOSE The corticobulbar tract is a potential neural pathway involved in swallowing. The frontal operculum, insular cortex, corona radiata and internal capsule, which are frequently involved in middle cerebral artery (MCA) strokes, are locations in which lesions cause dysphagia. However, it is unclear whether the locations are linked to the corticobulbar tract or whether corticobulbar tract integrity is associated with dysphagia severity. This study aimed to assess the association between corticobulbar tract integrity and dysphagia severity after MCA stroke. METHODS Thirty dysphagic patients after MCA stroke and 27 healthy controls were examined. Diffusion tensor imaging (DTI)-derived parameters of the corticobulbar tract were compared between patient and control groups. Next, patients were divided into mild and moderate-to-severe dysphagia groups, and DTI-derived parameters of the corticobulbar tract were compared between the subgroups. Logistic regression analysis was used to determine the association between corticobulbar tract integrity and dysphagia severity. RESULTS The tract volume (TV) of the affected corticobulbar tract was lower in dysphagic patients than in healthy controls (P < 0.001). According to dysphagia severity, TV of the unaffected corticobulbar tract was higher in the mild dysphagia group than in the moderate-to-severe dysphagia group (P = 0.012). TV of the unaffected corticobulbar tract was independently associated with dysphagia severity according to the logistic regression model (adjusted odds ratio 0.817, 95% confidence interval 0.683-0.976). CONCLUSIONS The corticobulbar tract was affected after MCA stroke and may be associated with dysphagia. A higher corticobulbar TV in the unaffected hemisphere was indicative of better swallowing function in dysphagic patients after MCA stroke.

Abstract
The formation of an immunological synapse (IS) on recognition of a cancer cell is the main mechanism underlying the natural killer (NK)-cell-mediated killing of tumor cells. Herein, an integrative strategy for cancer therapy against solid tumors is reported, in which alterations in the cleft of IS, following the secretion of acidic granular content, are utilized as a trigger for the delivery of chemotherapeutic drugs. NK cells are decorated with the IS-environment-responsive micellar system to ensure the release of the payload when they attack cancer cells. Using this strategy, the immunological cytotoxic killing effect of NK cells against solid tumors is reinforced with the site-specific diffusion of chemotherapeutic agents. Harnessing the intrinsic mechanism for the recognition of abnormal cells and the tumor-homing effect of NK cells limit the adverse systemic effects of chemotherapeutic drugs. This approach may provide a pragmatic platform for the universal and effective utilization of IS formation.

Abstract
Despite the approval of oncolytic virus therapy for advanced melanoma, its intrinsic limitations that include the risk of persistent viral infection and cost-intensive manufacturing motivate the development of analogous approaches that are free from the disadvantages of virus-based therapies. Herein, we report a nanoassembly comprised of multivalent host-guest interactions between polymerized paclitaxel (pPTX) and nitric oxide incorporated polymerized β-cyclodextrin (pCD-pSNO) that through its bioactive components and when used locoregionally recapitulates the therapeutic effects of oncolytic virus. The resultant pPTX/pCD-pSNO exhibits significantly enhanced cytotoxicity, immunogenic cell death, dendritic cell activation and T cell expansion in vitro compared to free agents alone or in combination. In vivo, intratumoral administration of pPTX/pCD-pSNO results in activation and expansion of dendritic cells systemically, but with a corresponding expansion of myeloid-derived suppressor cells and suppression of CD8+ T cell expansion. When combined with antibody targeting cytotoxic T lymphocyte antigen-4 that blunts this molecule's signaling effects on T cells, intratumoral pPTX/pCD-pSNO treatment elicits potent anticancer effects that significantly prolong animal survival. This formulation thus leverages the chemo- and immunotherapeutic synergies of paclitaxel and nitric oxide and suggests the potential for virus-free nanoformulations to mimic the therapeutic action and benefits of oncolytic viruses.

Abstract
Sonodynamic therapy utilizes ultrasound (US)-responsive generation of reactive oxygen species (ROS) from sonosensitizer, and it is a powerful strategy for anti-cancer treatment in combination with chemotherapy. Herein, we report a precisely designed sonodynamic chemotherapeutics which exhibits US-responsive drug release via ROS generation from co-loaded sono-sensitizer. Doxorubicin (DOX)-coordinated titanium dioxide nanoparticles (TNPs) were encapsulated with polymeric phenyboronic acid (pPBA) via phenylboronic ester bond between pPBA and DOX. Loaded DOX was readily released under US irradiation due to the ROS-cleavable characteristics of phenylboronic ester bond. The size of nanoparticles was around 200 nm, and DOX was released by ROS generated under US irradiation. Tumor targeting by PBA moiety, intracellular ROS generation, and combined therapeutic effect against tumor cells were confirmed in vitro. Finally, we demonstrated high tumor accumulation and efficient tumor growth inhibition in tumor-bearing mice under US irradiation, which revealed potential as a multi-functional agent for sonodynamic chemotherapy.

Abstract
Abstract
Nanoparticle-based delivery system has been attempted for a couple of decades for cancer immunotherapy (CIT) to modulate immune responses and reduce off-target side effect. For the successful CIT, the extent of antigen presentation by dendritic cell (DC) that phagocytizes tumor associated antigen (TAA) in tumor site and migrates to tumor draining lymph node (TDLN) for an activation of T-cells. For this, recent studies have been trying to make tumor tissue releases TAAs directly, increasing the chance for antigen presenting cells (APCs) to encounter the neoantigens. Photodynamic therapy (PDT), a conventional cancer therapeutic manner that generates reactive oxygen species (ROS) from adjacent oxygen by photosensitizer (PS) under irradiation of light, could induce release of damage-associated molecular patterns (DAMPs) and promote activities of immune cells, along with release of TAAs. Furthermore, PDT mediated generation of ROS is well known as neutrophil chemotaxis, potentiating capability for DC recruitment via granule enzymatic processing the prochemerin into chemerin. Taken together, a PDT can induce both tumor cell death and recruiting DCs, followed by uptake of the as-generated cell debris by APCs which increases the antigen presentation process and further activation of antitumor immune responses. Herein, to introduce PDT-induced immunologic alterations into CIT, we devised the nanoparticle-based delivery system that fulfills a few key requirements: 1) internalized efficiently by the cells at the target site, while the cargo is protected from degradation and scavenging by macrophages during circulation; 2) induces the release of tumor proteins and deliver adjuvant to activate APCs for prolonged immune reaction. In this study, we have developed a MSN-based hypoxia-responsive PS/adjuvant nanocomplex, denoted as CAGE, to enable photodynamic therapy assisted CIT. The surface of chlorin e6 (Ce6)-doped mesoporous silica nanoparticle was decorated with glycol chitosan (GC) and PEG via azobenzene linker, a hypoxia-responsive labile linker. CpG, a short oligonucleotide immunomodulator known to activate the DCs, was loaded onto the surface of CAGE by electrostatic interaction with GC. It was designed that azobenzene linker could be cleaved under intrinsic tumor hypoxia as well as abrupt consumption of local oxygen induced by photodynamic effect, leading to both a detachment of PEG for the tumor specific retention of MSNs and release of CpG/GC complexes. Due to the photodynamic effect of PS and delivery of CpG, the population of tumor infiltrating DCs and its maturation ratio were significantly elevated. An improved activity of DCs, combined with generation of tumor debris by photodynamic effect, was synergistically resulted in increase of antigen presentation of DCs, exhibiting remarkable inhibition of tumor growth in vivo.

Abstract
A key factor for successful cancer immunotherapy (CIT) is the extent of antigen presentation by dendritic cells (DCs) that phagocytize tumor-associated antigens (TAA) in the tumor site and migrate to tumor draining lymph nodes (TDLN) for the activation of T cells. Although various types of adjuvant delivery have been studied to enhance the activity of the DCs, poor delivery efficiency and depleted population of tumor infiltrating DCs have limited the efficacy of CIT. Herein, we report a hypoxia-responsive mesoporous silica nanocarrier (denoted as CAGE) for an enhanced CIT assisted by photodynamic therapy (PDT). In this study, CAGE was designed as a hypoxia-responsive transforming carrier to improve the intracellular uptake of nanocarriers and the delivery of adjuvants to DCs. Furthermore, PDT was exploited for the generation of immunogenic debris and recruitment of DCs in a tumor site, followed by enhanced antigen presentation. Finally, a significant inhibition of tumor growth was observed in vivo, signifying that the PDT would be a promising solution for DC-based immunotherapy.

Abstract
BACKGROUND AND PURPOSE Diagnosis of pharyngeal dysphagia caused by myasthenia gravis (MG) based on clinical examination alone is often challenging. Flexible endoscopic evaluation of swallowing (FEES) combined with Tensilon (edrophonium) application, referred to as the FEES-Tensilon test, was developed to improve diagnostic accuracy and to detect the main symptoms of pharyngeal dysphagia in MG. Here we investigated inter- and intra-rater reliability of the FEES-Tensilon test and analyzed the main endoscopic findings. METHODS Four experienced raters reviewed a total of 20 FEES-Tensilon test videos in randomized order. Residue severity was graded at four different pharyngeal spaces before and after Tensilon administration. All interpretations were performed twice per rater, 4 weeks apart (a total of 160 scorings). Intra-rater test-retest reliability and inter-rater reliability levels were calculated. RESULTS The most frequent FEES findings in patients with MG before Tensilon application were prominent residues of semi-solids spread all over the hypopharynx in varying locations. The reliability level of the interpretation of the FEES-Tensilon test was excellent regardless of the rater's profession or years of experience with FEES. All four raters showed high inter- and intra-reliability levels in interpreting the FEES-Tensilon test based on residue clearance (kappa = 0.922, 0.981). The degree of residue normalization in the vallecular space after Tensilon application showed the highest inter- and intra-rater reliability level (kappa = 0.863, 0.957) followed by the epiglottis (kappa = 0.813, 0.946) and pyriform sinuses (kappa = 0.836, 0.929). CONCLUSION Interpretation of the FEES-Tensilon test based on residue severity and degree of Tensilon clearance, especially in the vallecular space, is consistent and reliable.

Abstract
Since the discovery that nano-scaled particulates can easily be incorporated into tumors via the enhanced permeability and retention (EPR) effect, such nanostructures have been exploited as therapeutic small molecule delivery systems. However, the convoluted synthetic process of conventional nanostructures has impeded their feasibility and reproducibility in clinical applications. Herein, we report an easily prepared formulation of self-assembled nanostructures for systemic delivery of the anti-cancer drug doxorubicin (DOX). Phenylboronic acid (PBA) was grafted onto the polymeric backbone of poly(maleic anhydride). pPBA-DOX nanocomplexes were prepared by simple mixing, on the basis of the strong interaction between the 1,3-diol of DOX and the PBA moiety on pPBA. Three nanocomplexes (1, 2, 4) were designed on the basis of [PBA]:[DOX] molar ratios of 1:1, 2:1, and 4:1, respectively, to investigate the function of the residual PBA moiety as a targeting ligand. An acid-labile drug release profile was observed, owing to the intrinsic properties of the phenylboronic ester. Moreover, the tumor-targeting ability of the nanocomplexes was demonstrated, both in vitro by confocal microscopy and in vivo by fluorescence imaging, to be driven by an inherent property of the residual PBA. Ligand competition assays with free PBA pre-treatment demonstrated the targeting effect of the residual PBA from the nanocomplexes 2 and 4. Finally, the nanocomplexes 2 and 4, compared with the free DOX, exhibited significantly greater anti-cancer effects in vitro and even in vivo. Our pPBA-DOX nanocomplex enables a new paradigm for self-assembled nanostructures with potential biomedical applications.

Abstract
BACKGROUND AND PURPOSE The Gugging Swallowing Screen (GUSS) is a tool to screen aspiration risk in acute stroke. We aimed to replicate its validity in a larger second cohort of patients with acute stroke, including the more severe with a National Institutes of Health Stroke Scale (NIHSS) ≥ 15. METHODS In a prospective, double-blind design, the GUSS was validated with the Fiberoptic Endoscopic Evaluation of Swallowing scale. Patients were categorized into different stroke severities as assessed by the NIHSS, and the diagnostic properties were calculated separately for each subgroup. RESULTS A total of 100 patients with acute stroke were evaluated consecutively at a mean 1.7 ± 2.2 days after stroke. With the GUSS cut-off value of 14 points, the GUSS screened aspiration risk with a 96.5% sensitivity and 55.8% specificity (area under the curve, 0.76; 95% CI, 0.67-0.84), which corresponded well with the original publication. In the NIHSS < 5 group, the sensitivity and specificity levels were 71.4% and 88.8%, respectively. In the NIHSS ≥ 15 group, these levels changed to 100% and 20%, respectively. The high failure rate in completing the first part of the GUSS in the latter group was related to the low specificity. Diet recommendations following the GUSS were more conservative than those after Fiberoptic Endoscopic Evaluation of Swallowing. In particular, the GUSS overestimated the need for nasogastric tube feeding. CONCLUSIONS This is the first time that a swallowing screening tool for patients with acute stroke has been revalidated in a larger population from another stroke center. The validity of a swallow screening test may vary according to different stroke severities.

Abstract
Exposure to alcohol during adolescence exerts long-term effects on the adult brain stress circuits, causing many changes that persist into adulthood. Here we examined the consequences of adolescent intermittent ethanol (AIE, administered from postnatal day (PND) 28-42) on the hypothalamic-pituitary-adrenal (HPA) axis-related brain circuitry of rats challenged with intragastric (ig) administration of alcohol in adulthood (PND 70-71). Both male and female adolescent rats were exposed to alcohol vapors, while controls did not receive the drug, to assess whether AIE alters adult alcohol response in a sex-specific manner. We demonstrated that AIE increased paraventricular nucleus (PVN) Avp mRNA levels during late (PND 42) but not middle (PND 36) adolescence in males. While an alcohol challenge administered to 70-71-day-old rats increased Crf mRNA levels in males and Avp mRNA levels in females, AIE blunted both effects. These results suggest that AIE produced long-lasting changes in the responsiveness of the HPA axis to a subsequent alcohol challenge in a sex-specific manner. Furthermore, AIE altered adrenergic brain stem nuclei involved in stress responses in adulthood, resulting in increased numbers of phenylethanolamine N-methyltransferase (PNMT) neurons in male C2 and female C1 regions. This tended to enhance activation of the male C2 nucleus upon alcohol challenge. Collectively, these results suggest that AIE exerts long-term effects on the ability of the PVN to respond to an alcohol challenge in adulthood, possibly mediated by catecholaminergic input from the brain stem to the PVN.

Abstract
TGF-β is a mediator of lung fibrosis and regulates the alveolar epithelial type II cell phenotype. TGF-β can induce epithelial mesenchymal transition of idiopathic pulmonary disease and cancer metastasis. Peroxisome proliferator-activated receptor gamma co-activator 1-alpha (PGC-1 α) is a key metabolic regulator that stimulates mitochondrial biogenesis and promotes remodeling of muscle tissue to oxidative fiber-type composition. Here, we report that the induction of TGF-β decreased mRNA expression of PGC-1α, and PGC-1 target genes, such as the transcription factors NRF-2, ERR-α, and PPAR-γ in lung epithelial A549 cells. In addition, TGF-β led to the reduction of super oxide dismutase 2 (anti-oxidant enzyme), cytochrome C (electron transport chain in mitochondria), and MCAD (a mitochondrial β-oxidant enzyme) in A549 cells. Together, our results suggest that TGF-β may suppress the transcriptional activity of the genes related to mitochondrial biogenesis or function. This mechanism may provide a novel insight into the understanding of fibrosis disease.

Abstract
282 Background: In advanced biliary tract cancer, after failure of first-line chemotherapy, salvage chemotherapy has not yet been established and the prognostic factors in salvage setting have not been widely known. The purpose of this study was to evaluate the efficacy and safety of iFAM as salvage chemotherapy in biliary tract cancer and to reveal the prognostic factors. Methods: Eligibility included: 1) age 18-75, 2) histologically confirmed biliary tract cancer, 3) previously treated with palliative first-line chemotherapy, 4) ECOG PS 0-2, 5) adequate organ function. iFAM consisted of 5-FU 800 mg/m2 over 12 hour on days 1-5, doxorubicin 30 mg/m2 on day 1, and mitomycin-C 8 mg/m2 on day 1, every 4 weeks. Results: Between February 2003 and August 2009, 50 patients (pts) were enrolled. The median age was 57.3 yrs (range: 26.0-71.5 yrs), and there were 33 men (66%). 32 pts (64%) had ECOG PS 0-1 and 18 pts (36%) had PS 2. Biliary tract cancers were extrahepatic cholangiocarcinoma (30%), intrahepatic cholangiocarcinoma (30%) and gallbladder cancer (40%). Previous chemotherapy mainly consisted of gemcitabine-based and 5-FU-based regimens. Median cycles of iFAM were 2 (range: 1-6). Best responses to iFAM were PR in 2 (4%) pts and SD in 9 (18%), that is response rate was 4% and disease control rate was 22% (95% CI: 7.35-28.65). The median PFS and OS were 2.2 (95% CI: 2.0–2.4) months and 5.0 (95% CI: 3.3–6.7) months, respectively. Grade 3/4 hematologic toxicities were neutropenia (10%), anemia (2%), and thrombocytopenia (8%). Frequent nonhematologic toxicities were alopecia (34%), stomatitis (28%), vomiting (24%), and diarrhea (12%), which were grade 1/2. ECOG PS (0-1 vs 2) was significant prognostic factor for both PFS (p=0.029) and OS (p=0.025). Poor response to previous chemotherapy (p=0.031) were poor prognostic factors for OS. Conclusions: iFAM is an effective and safe treatment option in refractory biliary tract cancer and can be considered as salvage regimen, especially for patients with good PS and good response to previous chemotherapy. No significant financial relationships to disclose.

Abstract
362 Background: Bevacizumab (BEV), a humanized anti-VEGF monoclonal antibody, has demonstrated clinical efficacy in combination with 5-FU-based regimens in patients with metastatic colorectal cancer. The therapeutic impact of concurrent BEV with either FOLFOX4 or XELOX chemotherapy in the adjuvant setting was evaluated in this international, controlled phase III trial. Methods: Eligible patients had high-risk stage II or stage III colon cancer and had undergone surgical resection. Patients were randomly assigned to one of three treatment groups and stratified by geographic region and tumor stage: Arm A: FOLFOX4 on weeks 1–24; Arm B: FOLFOX4 + BEV on weeks 1–24, then BEV alone on weeks 25–48; Arm C: XELOX + BEV on weeks 1–24, then BEV alone on weeks 25–48. The primary endpoint was disease-free survival (DFS) for patients with stage III colon cancer; secondary endpoints included overall survival (OS), and safety. DFS/OS follow-up assessments were performed every 6 months after randomization for 4 years, then annually until recurrence or death. Results: 3,451 (2,867 stage III) patients were enrolled between December 2004 and June 2007; median age was 58–59 years. Median duration of follow-up was 48 months (range 0–66 months). BEV did not prolong DFS or OS when added to either FOLFOX4 or XELOX in patients with stage III colon cancer based on the final efficacy analysis conducted in September 2010. Efficacy results favored the chemotherapy-alone control arm. Numerically more relapses and deaths occurred in both the BEV arms compared to control. The observed adverse events were consistent with those previously reported in pivotal trials of BEV across tumor types for approved indications. Conclusions: The primary endpoint of the AVANT study was not met. BEV does not prolong DFS when added to either FOLFOX4 or XELOX in patients with stage III colon cancer. The safety profile of BEV was consistent with prior study results. [Table: see text]

Abstract
Abstract
PurposeThe tumor suppressor gene RASSF1 (Ras association domain family member 1) regulates cell cycle, progression, apoptosis, and microtubule stability, and is inactivated by promoter hypermethylation in breast cancer. We analyzed the SNPs in RASSF1 and their predictive and prognostic value in stage II or III breast cancer patients who received neoadjuvant docetaxel/doxorubicin chemotherapyMethodsA total of 139 stage II or III breast cancer patients who received neoadjuvant docetaxel/doxorubicin chemotherapy were enrolled in this study. The patients received three cycles of neoadjuvant chemotherapy followed by curative surgery, and received additional three cycles of docetaxel/doxorubicin chemotherapy as an adjuvant. Germline DNA from peripheral blood mononuclear cells was extracted. The genotypes were performed using Illumina GoldenGate® Assay. We analyzed 3 SNPs in RASSF1 genes: rs3213621 T>C in 3'UTR, rs2073499 G>A in intron, and rs2073498 C>A in exon 3 Ala133Ser.ResultsThe overall radiologic response rate (RR) for neoadjuvant chemotherapy was 79.8% and 10 patients (7.2%) achieved a pathologic complete remission (pCR). None of the SNPs were correlated with radiologic RR or pCR rate. SNP in intron of RASSF1 (rs2073499) was associated with relapse free survival (RFS). RFS was longer in GA/AA genotype than GG genotype (Hazard ratio [HR]=0.374, p=0.034) After adjusting age and hormone status, prognostic value of RASSF1 SNP remained significant (HR=0.393, p=0.050). Other two SNPs were not significantly associated with RFS.ConclusionsThe GA/AA genotype in SNP of RASSF1 (rs2073499) is associated with significantly longer RFS than the GG genotype. Further research is warranted to identify the biologic characteristics of RASSF1.
