AbstractFacial features are important sources of information about perceived trustworthiness. Masks and protective clothing diminish the visibility of facial cues by either partially concealing the mouth and nose or covering the entire face. During the pandemic, the use of personal protective equipment affected and redefined who trusts whom in society. This study used the classical investment game of interpersonal trust with Chinese participants to explore the impact of occlusion on interpersonal trust. Faces with moderate initial trustworthiness were occluded by a mask or protective clothing in Experiment 1 and were digitally occluded by a square in Experiment 2, and faces with three levels of initial trustworthiness were occluded by a mask in Experiment 3. Results showed that both undergraduates (Experiment 1a) and non-student adults (Experiment 1b) perceived the faces with protective clothing as more trustworthy than faces wearing standard masks and faces not wearing masks. Faces with the top halves showing were perceived as trustworthy as full faces, while faces with the bottom halves showing were perceived as less trustworthy. The effect of masks is weak and complex. Masks reduced participants’ trust in faces with high initial trustworthiness, had no effect on faces with low and moderate initial trustworthiness, and only slightly increased the trust of undergraduates in faces with moderate initial trustworthiness. Our findings indicate that the lack of information caused by occlusion and the social significance associated with occlusion collectively affect people’s trust behavior in Chinese society. We believe the findings of this study will be useful in elucidating the effects of personal protective equipment usage on perceptions of trustworthiness.

Abstract
Background
Cotton (Gossypium hirsutum L.) is one of the most significant fibre and cash crops and plays an important role in Indian industrial and agricultural economies. However, over the years quantity and quality have been hampered by the pest leafhopper. Leafhopper alone has been shown to cause yield losses of up to 40%. In this study, screening and evaluation were performed to identify and categorize 100 cotton genotypes along with 5 checks as resistant, moderately resistant, sensitive and highly sensitive to leafhoppers.

Results
A total of hundred genotypes were evaluated along with five checks for leafhopper resistance. Based on the screening results, a total of 19 genotypes were resistant to leafhoppers, which was on par with the findings of the check KC 3. The contents of total soluble sugar, total soluble protein, and total free amino acids were significantly positively correlated with the mean grade, whereas total phenols content and trichome density were significantly negatively correlated with the susceptibility grade. However, based on screening and biochemical analysis, the genotypes KC 2, JR-23, Samaru-26-T, D 4, TCH 1728, RS 253, and B-61-1862 exhibited high resistance to leafhopper.

Conclusion
According to the findings of this study, choosing genotypes with high total phenolics content together with high trichome density and low contents of total soluble sugar, total soluble protein, and free amino acids may aid in the development of resistant genotypes.

AbstractIn order to identify the time-varying frequency and amplitude of structural vibration based on the bridge structural health monitoring data and obtain the cable force of cable-stayed bridges in real time, a spectrum analysis method based on amplitude and phase estimation (APES) was proposed in this study. The amplitude spectrum of the acceleration data is first calculated by the APES method, the real-time spectrogram of the cable is obtained by the sliding window method. Then the modal frequency and amplitude are automatically extracted from the real-time spectrum by using a frequency extrusion post-processing technique, which can be regarded as the average value of the instantaneous frequency and amplitude respectively. Next, the fundamental frequency of the cable is extracted by using an automatic identification method, and the performance of the proposed method is verified. Finally, real-time scoring of cable forces and structural condition assessment is achieved with consideration of the moderation index model as well as the material strength. The results show that the APES method can use shorter calculation samples than the traditional Fast Fourier Transform (FFT) to obtain higher resolution and more accurate amplitude, which provides a theoretical basis for the real-time identification of fundamental frequency based on short-term monitoring data. The frequency extrusion post-processing-algorithm can reduce the spectrum recognition delay and improve timeliness of the cable force evaluation. The time-varying cable force with an interval of 10 s can be used to reflect the health status of the cable in time. The research results can provide technical support for the real-time extraction of cable force of long-span cable-stayed bridges, and can also provide an effective basis for component condition evaluation and bridge maintenance decision-making.

6007 Background: We previously reported that surgery to the primary site with hypoxia-directed de-escalated radiation to the neck for human papillomavirus associated oropharyngeal carcinoma (HPV+ OPC) can lead to excellent oncologic outcomes. We now report the results of a successor multi-center phase II trial of hypoxia-directed de-escalated chemoradiotherapy without surgery for HPV+OPC. Methods: HPV+ OPC (T0-2/N1-N2c/AJCC 7th) patients were eligible for enrollment. Tumors without evidence of hypoxia on 18F-FMISO (fluoromisonidazole) PET received de-escalated chemoradiation to 30Gy while those with hypoxia received chemoradiation to 70Gy. The primary objective was achieving a 2-year locoregional control (LRC) of 95% (failure was locoregional recurrence where surgical salvage was unfeasible) with a 7% non-inferiority margin. We enrolled a total of 158 subjects upfront to account for a 5% loss due to death (of reasons other than cancer) or follow-up. Secondary objectives were local failure (LF), regional failure (RF), distant metastasis (DM), overall survival (OS), toxicities, and patient-reported MD Anderson Dysphagia Inventory (MDADI) scores. LF, RF, and DM were estimated using the Cumulative Incidence Function, and OS was estimated using the Kaplan-Meier method. Results were reported up to 1/31/2024. Results: From 4/28/20-4/17/23, 158 HPV+ OPC patients were enrolled where150 patients were eligible for analyses. Patient characteristics: Tonsil (43%); Base of Tongue (47%); unknown primary (10%); >/=10 pack years (22%); T0 (9%), T1 (44%), T2 (47%); N1 (14%), N2a (11%), N2b (59%), N2c (16%). 111 (74%) received 30Gy; 95% cisplatin. With 24 months (8-43) of median follow-up, the 2-year LF, RF, DM rates were 4.2%, 6.9%, 2.0%, respectively. The 2-year overall survival probability was 99%. Only 2 patients could not undergo salvage surgery [one 30Gy (second recurrence); one 70Gy (M1)], both received systemic therapy with durable response. Acute grade 3-4 toxicities were 32% (67% neutropenia). Mean MDADI scores: 92.93 (baseline); 68.24 (3 weeks), 91.45 (4 months) after chemoradiation. Conclusions: These early data indicate that major de-escalation to 30Gy based on hypoxia status achieved significant toxicity reduction without compromise in survival for HPV+ OPC treated with chemoradiation without surgery.

6020 Background: Squamous cell carcinoma (SCC) arising from paranasal sinus and nasal cavity (PNSNC) is often diagnosed at locally advanced stage. Neoadjuvant strategies have been explored to improve prognosis and facilitate organ preservation. The efficacy of triplet neoadjuvant chemotherapy (NAC) has not been established prospectively. We conducted a phase II trial of neoadjuvant docetaxel/5-FU/cisplatin (DFP) combined with prophylactic pegteograstim in unresectable, locally advanced PNSNC (KCT0003377). Methods: Eligible patients had unresectable SCC of PNSNC, were aged 19-75, had an ECOG performance status of 0/1, and demonstrated adequate organ function. Patients with distant metastasis were excluded. Criteria for unresectability included tumor or lymph node fixation, clinical T3/4 stage, or potential compromise of critical organ function (e.g., necessitating eyeball exenteration). NAC comprised three cycles of docetaxel (75mg/m2 on Day 1), cisplatin (75mg/m2 on Day 1, 60mg/m2 for those aged ≥65), and 5-FU (1,000mg/m2 on Days 1-4) administered every 3 weeks. Prophylactic pegteograstim (6mg) was administered on Day 6 or 7. The primary outcome was the overall response rate (ORR), with secondary outcomes including progression-free survival (PFS), the eyeball preservation rate at 24 months, and safety. The study required 28 patients to achieve a power of 80% (P0=0.45, P1=0.70, α-error=0.05, 10% dropout rate). Results: Between 2019 and 2023, 28 patients were screened, and 27 received at least one cycle of NAC. The median age was 58 years (range: 41-71), with 24 males. Seventeen had maxillary sinus origin, and ten had nasal cavity origin. Twenty-two patients had T4 disease, and six had N2 disease. The ORR was 64.3% (5 complete responses, 13 partial responses). Post-NAC treatments included surgery alone (n=2), concurrent chemoradiotherapy (CCRT) (n=15), surgery followed by CCRT (n=2), or radiotherapy (RT) (n=5). Procedures performed were total maxillectomy (n=4), partial maxillectomy (n=3), and endoscopic sinus surgery (n=2). With a median follow-up of 21.5 months (range: 0.1-53.0), the 2-year PFS and eyeball preservation rate were 64% and 100%, respectively. Fourteen patients experienced Grade ≥3 adverse events (AEs): hematologic (46.4%), non-hematologic (14.3%), with Grade 3/4 neutropenia (32.1%) and febrile neutropenia (14.3%). Dose reduction or delay occurred in 9 patients (33.3%). One patient died on Day 6 of cycle 1. Conclusions: DFP NAC demonstrated promising efficacy and an excellent eyeball preservation rate with manageable toxicity. DFP NAC with prophylactic pegteograstim, could be a reasonable option for patients with locally advanced SCC of the PNSNC. Follow-up is ongoing. Clinical trial information: KCT0003377 .

Published: June 2024

6063 Background: The prognosis of early oral squamous cell carcinomas (OSCC) is strongly correlated with local disease control. However, patients with T1-T2 OSCC operated with clear margins have a 5-year local relapse rate of 10 to 15%. An accurate evaluation of the microscopic residual disease (MRD) is therefore essential. Interestingly, innovative techniques have recently been developed to detect circulating tumor DNA. Methods: A prospective multicenter trial based on patients with T1-T2 OSCC treated surgically with clear margins, was designed to assess the feasibility of a molecular analysis (tetranucleotide instability) of these margins to evaluate a potential MRD while adapting the postoperative strategy (NCT00232960). We, then, evaluate the feasibility of detecting MRD in the margins by identifying specific molecular abnormalities in the primary tumor with Whole Exome Sequencing (WES) and explore them in margins with deep target NGS panel (TGS) and digital PCR (dPCR) for hotspot mutations. Results: 310 patients were included initially with 216 tumor/margins samples available for molecular analysis. After a standard pathologic analysis, all surgical margins were negative.Median follow-up was 58 months [30;83]. Tumor was informative for tetranucleotide instability analysis in 63% of cases. Positive molecular margins were observed in 17.3% of cases, leading to a postoperative treatment (surgery or radiotherapy). In informative tumors, molecularly driven treatment seemed to lower the 5-year local recurrence rate from 14.1% to 6.4% (p=0.15). Among this initial cohort, 108 primary tumors were secondarily screened by WES to find mutations of interest, with an informativity rate of 75%. Positive molecular results (TGS or dPCR), with at least one positive margin, were observed in 19.4% of patients. Then, analyzing retrospectively the oncologic outcomes, we observed a significant benefit for local control at 5 years for patients with TGS-dPCR negative results in all margins compared to pathologic negative margins (91.7% versus 64.1%, p=0.02). Conclusions: To our knowledge, this is the first report of local MRD assessment after surgery using NGS.Molecular analysis of resection margins for early OSCC lead to a better evaluation of MRD and personalized postoperative decision making to improve local control.

Published: June 2024

6069 Background: Perimarginal nodes (PMN) are a group of perifacial lymph nodes that lie in close relationship with marginal mandibular nerve (MMN). They lie in the lymphatic drainage pathway of gingivo-buccal cancers (GBC), above the lower border of mandible which forms the superior limit of conventional neck dissection and thus remain unaddressed. With reported incidence of metastasis as high as 20.5%, we aimed to explore incidence of PMN metastasis in GBC, its correlation with histopathological tumor and nodal characteristics. Methods: A prospective study was conducted on 112 consecutive treatment naïve patients of GB squamous cell carcinoma. Patients with unresectable nodal disease, distant metastasis and prior radiotherapy or surgery to neck were excluded. PMN dissection was performed in the quadrangle bounded superiorly by the mandibular alveolar ridge, inferiorly by lower border of mandible, anteriorly by mental foramen and posteriorly by anterior border of masseter. On histopathological analysis, serial step sectioning and cytokeratin immunohistochemistry were performed. Prospective clinical characteristics analyzed were subsite, clinical tumor, nodal stage, location of primary and clinical skin involvement. PMN positivity was correlated with demographic, clinical, nodal status. Histopathological characteristics analyzed included tumor grade, pathological tumor, nodal stage, tumor size, skin and/or bone involvement, depth of invasion, Brandwein Gensler histological risk score and lympho-vascular emboli. MMN functional outcome was graded according to House-Brackman (HB) grading recorded at 3 and 6 months post-operatively. Results: Baseline characteristics are summarized in the table. The PMN were identified histologically in 75.89% (85/112) patients. Metastasis in these nodes were identified in 15.2% (17/112) patients. Our study revealed an occult PMN metastasis of 16.67% (13/78). None of the pre-operative clinical factors was found to be significant in predicting incidence of metastasis. Higher nodal burden (p=0.01) and pathological skin involvement (p=0.03) had statistically significant odds of having PMN metastasis on multivariable analysis. At 6 months follow-up, none of the patients had any MMN functional deformity at rest. Conclusions: There is a high incidence of occult PMN metastasis from gingivo-buccal complex cancer. High nodal stage and pathological skin involvement are independent adverse prognostic factors for PMN metastasis. The limits of conventional neck dissection should be expanded to include clearance of PMN in all cases of gingivo-buccal cancers. [Table: see text]

6074 Background: The incidence rate of HNSCC in Hunan China are notably higher than in other regions, likely due to the high prevalence of betel nut chewing. Therefore, we conducted a study to examine the PD-L1 expression in newly diagnosed locally advanced (stage III-IVB) HNSCC patients. Methods: 1. We conducted a retrospective analysis of the PD-L1 expression (represented as CPS) in pre-treatment biopsy tissues from locally advanced HNSCC. 2. 57 patients received neoadjuvant treatment consisting of nab-paclitaxel+ cisplatin+ pembrolizumab. The efficacy of the treatment was evaluated using pathology assessments. Results: 1. A total of 373 patients were included. The top five primary sites of the tumors were the tongue(32.17%), Buccal oris (20.91%), oropharynx (10.19%), hypopharynx(9.92%), and gingiva(7.77%). The proportion of patients with PD-L1 CPS≥20 (55.23%) was significantly higher than the 43.20% reported in the KEYNOTE-048 study. Furthermore, the subgroup was even higher in the buccal oris (70.51%) and gingiva (72.41%). 2. A total of 57 patients were tested for PD-L1 CPS and received neoadjuvant treatment.After surgery, 22/57 (38.60%) achieved pathological complete response (pCR) or major pathological response (MPR), 29/57 (50.88%) achieved partial pathological response (pPR), resulting in an overall response rate (ORR) of 89.47%. In the PD-L1 CPS ≥20 group, the ORR was as high as 91.89% (34/37). 3. Among the 57 patients, 36 patients had lymph node metastasis. After treatment, 15/36 patients (41.67%) achieved pCR/MPR in lymph nodes, 7/36 patients (19.44%) achieved pPR, resulting in an ORR was 61.11% (22/36). Conclusions: 1. The oral cavity is the most common primary in HNSCC in Hunan,China. In the locally advanced , the proportion of PD-L1 CPS ≥20 is higher than reported in other studies. 2. Regardless of PD-L1 expression, neoadjuvant treatment with nab-paclitaxel+ cisplatin+ pembrolizumab has shown a high rate of local disease control in newly diagnosed HNSCC patients. Additionally, the use of neoadjuvant therapy has improved the delineation of surgical safety margins, leading to 100% R0 resections in all 57 patients. 3. The response of the primary lesion in patients treated with neoadjuvant therapy is better than that of the lymph node. Patients with a well-responding primary lesion but multiple lymph node metastases should be closely monitored for the possibility of short-term systemic metastasis. [Table: see text]
Clinical validation of a mesenchymal gene expression signature for prognosis and treatment decision making in early-stage oral cavity squamous cell carcinoma.

6091 Background: Treatment for human papillomavirus (HPV)-negative oral cavity squamous cell carcinoma (OCSCC) includes surgical resection of the primary tumor, usually with elective or therapeutic neck dissection with adjuvant radiation or chemotherapy and radiation based on risk stratification. While therapeutic advances have been modest at best for over a century, the addition of chemotherapy to radiation has demonstrated benefit for the highest risk patient groups, although recurrence rates remain high for advanced-stage patients. Even more concerning, some early-stage patients demonstrate life-threatening relapses in the absence of biomarker guidance. Using retrospective analysis, our group and others have identified gene expression signatures that reveal molecular subtypes (classical, atypical, basal and mesenchymal) that could identify early-stage patients most likely to recur and are likely candidates for therapy escalation, such as chemotherapy plus radiation. We hypothesize that the mesenchymal (MS) gene expression subtype is associated with worse overall survival (OS) in early-stage, node-negative OCSCC compared to non-mesenchymal subtypes. Herein we present further clinical validation of our previously described 88-gene OCSCC classifier (Mayhew et al, 2022; PMID: 36147910). Methods: As part of a prospectively designed retrospective study, residual tumor samples and paired clinical data, including n-stage and survival, were collected for patients with node-negative OCSCC (IRB# 201706088 at Washington University in St. Louis). Using the NanoString nCounter platform, RNA was isolated and counts were generated according to the manufacturer’s specifications. Gene expression data were used to assign molecular subtypes, and associations with overall survival (OS) were investigated using Kaplan-Meier plots and cox models in patients who were pathologically node negative. Results: A total of n=137 patients had node-negative OCSCC and sufficient tumor quantity to generate molecular subtype results. Consistent with our previous findings, the MS subtype was strongly associated with inferior survival in both univariate (HR = 3.24, p = 0.0019) and multivariable (HR = 3.26, p = 0.0026) analyses, confirming a potential role for gene expression-based subtyping as a biomarker for prognostication and informing clinical treatment decisions. Conclusions: These findings confirm that the MS subtype is associated with significantly worse survival in surgically resected, early-stage OCSCC which typically demonstrate favorable outcomes. Also, these findings strongly suggest value in gene expression subtyping for prognostication and treatment decision-making in OCSCC patients and warrant the further development of the 88-gene classifier as a diagnostic test for this clinically actionable patient population.
