Abstract
BACKGROUND Combining radiotherapy (RT) with immuno-oncology (IO) therapy (IORT) may enhance IO-induced antitumor response. Quantitative imaging biomarkers can be used to provide prognosis, predict tumor response in a non-invasive fashion and improve patient selection for IORT. A biologically inspired CD8 T-cells-associated radiomics signature has been developed on previous cohorts. We evaluated here whether this CD8 radiomic signature is associated with lesion response, whether it may help to assess disease spatial heterogeneity for predicting outcomes of patients treated with IORT. We also evaluated differences between irradiated and non-irradiated lesions. METHODS Clinical data from patients with advanced solid tumors in six independent clinical studies of IORT were investigated. Immunotherapy consisted of 4 different drugs (antiprogrammed death-ligand 1 or anticytotoxic T-lymphocyte-associated protein 4 in monotherapy). Most patients received stereotactic RT to one lesion. Irradiated and non-irradiated lesions were delineated from baseline and the first evaluation CT scans. Radiomic features were extracted from contrast-enhanced CT images and the CD8 radiomics signature was applied. A responding lesion was defined by a decrease in lesion size of at least 30%. Dispersion metrices of the radiomics signature were estimated to evaluate the impact of tumor heterogeneity in patient's response. RESULTS A total of 94 patients involving multiple lesions (100 irradiated and 189 non-irradiated lesions) were considered for a statistical interpretation. Lesions with high CD8 radiomics score at baseline were associated with significantly higher tumor response (area under the receiving operating characteristic curve (AUC)=0.63, p=0.0020). Entropy of the radiomics scores distribution on all lesions was shown to be associated with progression-free survival (HR=1.67, p=0.040), out-of-field abscopal response (AUC=0.70, p=0.014) and overall survival (HR=2.08, p=0.023), which remained significant in a multivariate analysis including clinical and biological variables. CONCLUSIONS These results enhance the predictive value of the biologically inspired CD8 radiomics score and suggests that tumor heterogeneity should be systematically considered in patients treated with IORT. This CD8 radiomics signature may help select patients who are most likely to benefit from IORT.

Abstract
PURPOSE To assess the efficacy and the tolerance of a split course hypofractionated (SCH) radiotherapy (RT) protocol in head and neck cancer (HNC) for eldery and/or unfit patients (pts). PATIENTS AND METHODS Pts with HNC treated by SCH-RT in two institutions were included retrospectively. The main SCH RT regimen was two courses of 30 grays (Gy)/10 fractions separated by 2-4 weeks, without any systemic therapy. RESULTS Between February 2012 and January 2019, 75 consecutive patients were analyzed. The median age was 80 years (range: 45.7-98.2) and 53 (70.7%) were men. Sixty-one (81.3%) pts had stage III/IV disease and 54 (72%) had at least two comorbidities. All of them were treated with intensity-modulated radiotherapy. Median follow-up was 10.6 months (range: 3.1-58.3). Local control at 12 and 24 months was 72.8% IC95%[62-85.5] and 51.7% IC95%[38.1-70.1] respectively. Progression free survival (PFS) at 12 and 24 months were 47.7% IC95%[37.4-60.8] and 41% IC95%[15-36.4] respectively, with a median of 11.5 months IC95%[8.9-17]. OS at 12 and 24 months were 60.4% IC95%[50-73.1] and 41% IC95%[30.6-54.9] respectively, with a median of 19.3 months IC95%[11.9-25.8]. Acute and late grade 3 or higher toxicities occurred for 6 (8%) and 3 (4%) pts. CONCLUSION The present SCH-RT regimen seems effective, well-tolerated and could represent an alternative to palliative strategies for pts deemed unfit for standard exclusive RT.

Abstract
Objective: To explore the reproductive health status of the female street cleaners in Chaoyang district of Beijing and its influencing factors. Methods: In July 2018, a total of 647 questionnaires were sent out to female road cleaning and sanitation workers in the whole district, 613 of which were valid, with an effective rate of 94.7%. Frequency or percentage (%) is used for statistical description of counting data, and mean standard deviation is used for measurement data. The influencing factors were analyzed by 2 test. Results: The average age of 613 female road sweepers in Chaoyang District of Beijing was 42.01 (SD=6.69) years old, including 535 married female workers (87.28%) , 356 middle school and below educated (58.08%) , 292 non Beijing registered (47.63%) , accounting for (/613) , (/613) female workers working hours >8 hours per day 110 (17.94%) , weekly rest <2 days 341 (55.63%) . 144 (23.49%) women workers did not have regular gynecological examination, 119 (19.41%) had reproductive tract infections, 177 (28.87%) had abnormal menstruation in recent 6 months. Drinking, sexual behavior outside marriage, night shift and job satisfaction were all the influencing factors (P<0.05) . The increasing age, working years, drinking, household registration in other places and the decreasing satisfaction of women workers' rights and interests protection were all the influencing factors (P<0.05) . Conclusion: The reproductive health status of female road sweepers in Chaoyang District of Beijing is not optimistic.

Abstract
BACKGROUND Area postrema syndrome (APS) is recognized as a core feature in neuromyelitis optica (NMO) diagnosis. Isolated APS can occur at NMO onset and frequently results in a delay of diagnosis, along with devastating secondary neurologic deficits. To date, few studies have characterized APS-onset neuromyelitis optica spectrum disorder (APSO-NMOSD). OBJECTIVE We aimed to describe the clinical and radiologic features of patients with APSO-NMOSD who are initially misdiagnosed in a cohort of patients from Zhengzhou, China. MATERIALS AND METHODS We identified 15 patients who presented with APS as an initial manifestation, based on the 2015 international consensus diagnostic criteria for NMOSD, and reviewed their demographic, clinical, laboratory, and magnetic resonance imaging (MRI) data. RESULT Fifteen patients (3 men, 12 women) aged 14-50 years old were included in our study. All patients presented with APS that included intractable nausea, vomiting, or hiccups (INVH) as the initial manifestation; many experienced a delay in diagnosis. Serum AQP4 was positive in eleven patients and myelin oligodendrocyte glycoprotein (MOG) in one patient. All patients had a linear medullary lesion or a linear medulla-spinal lesion on sagittal MRI. An "inverted V sign" on axial medulla oblongata images, representing a lesion involving the area postrema, was noted in seven patients in this study. CONCLUSIONS APS can occur as a sole and initial manifestation of NMOSD, often leading to misdiagnosis in the early process of disease. Identifying patients with an "inverted V" sign and a linear medullary lesion upon MRI examination can help to quickly identify APS patients and avoid further diagnostic delays.

Abstract
The DNA methylation statuses of the paired box 1 (PAX1) and zinc finger protein 582 (ZNF582) genes have shown promise in the detection of oral squamous cell carcinoma (OSCC). The aim of this study was to investigate the ability of PAX1 and ZNF582 methylation to distinguish OSCC and the adjacent normal tissue among cancer patients. This study included 67 patients with OSCC. The methylation levels of these two genes were analysed in tissue specimens (lesion site and adjacent normal site) and in oral swabs (lesion site and contralateral normal site). Levels of DNA methylation were higher at lesion sites than at the corresponding normal sites. According to receiver operating characteristics curve analysis, the area under the curve for PAX1 and ZNF582 methylation ranged from 0.73 to 0.82. No significant difference was observed between tissue specimens and oral swabs (PAX1, P= 0.41; ZNF582, P=0.28). For the oral swab, PAX1 methylation was more pronounced in bone invasion (Z=1.988, P= 0.047), and ZNF582 methylation was more pronounced in early-stage (Z=2.354, P= 0.02) and well-differentiated tumours (Z=3.731, P= 0.0002). Hypermethylated PAX1 and ZNF582 are effective biomarkers to distinguish lesion sites and corresponding normal sites in tissue specimens and oral swabs from OSCC patients.

Abstract
Conyzasaponins produced by the traditional Chinese herb Conyza blinii are oleanane-type saponins with a wide range of biological activities. Here, we identified a gene, designated CbCYP716A261, encoding a β-amyrin 28-hydroxylase in conyzasaponins biosynthesis. Ten full putative CYP sequences were isolated from Conyza blinii transcript tags. The CbCYP716A261 gene product was selected as the putative β-amyrin 28-hydroxylase by phylogenetic analysis and transcriptional activity analysis of methyl jasmonate-treated Conyza blinii. To identify the enzymatic activity, we performed enzymatic activity experiments in vitro and in vivo. The HPLC results revealed that CbCYP716A261 catalyzes the hydroxylation of β-amyrin at the C-28 position to yield oleanolic acid. Our findings provide new information about the conyzasaponin biosynthesis pathway and widen the list of isolated β-amyrin 28-hydroxylases.

Abstract
The management of early metastatic prostate cancer is based on systemic treatment by androgen deprivation therapy with or without chemotherapy or next-generation anti-androgen therapies. Local treatment of the prostate was initially used only to alleviate local symptoms. However, local radiotherapy of the prostate has been the subject of retrospective and prospective studies in patients with better prognostic factors, particularly in oligometastatic status. The results of these studies support that prostate radiotherapy can prolong the survival of patients with a low metastatic burden. This article states the biological bases, the main published and future published studies aimed to embed this strategy to optimize therapeutic management.

Abstract
Abstract
Background: The SARS-CoV-2 outbreak in Paris’ region significantly affected Gustave Roussy cancer center. Here, we report the Gustave Roussy experience during the SARS-CoV-2 outbreak. This outbreak has led to a rapid reorganization of cancer patients’ (pts) management, with two concurrent objectives. First, protect cancer pts, who may experience more severe form of the disease, from being infected by the SARS-CoV-2. Second, protect cancer pts from losing the chance to receive optimal, if not standard, cancer care.
Methods: Cancer pts with suspected SARS-CoV-2 infection were admitted at Gustave Roussy starting March, 12th. Screening indications have been adapted over the time. All the COVID19 pts positively tested and managed at Gustave Roussy between March 14th (1st positive case) and April 15th have been included in a redcap database. Pts and underlying oncological and COVID19 diseases characteristics have been collected. Cancer and COVID-19 managements, and outcomes have been assessed. The primary endpoint of this analysis was the clinical deterioration, defined as the need for O2 supplementation of 6l/min or more, or death of any cause.
Results: Overall, 7,251 cancer pts were managed at Gustave Roussy during this period of time, with 3616 being hospitalized. Based on our testing strategy, 1302 pts have been tested with 12% of them found positive for SARS-CoV-2. Among the first 137 cancer pts diagnosed with SARS-CoV-2, most cases were female (58%) with a median age of 61 years, including 36 pts (26%) ≥ 70 years. Most frequent underlying cancers were solid tumors (115) including breast (23), GI (18), head and neck (17), GU (17), GYN (17) malignancies or hemopathies (22). At time of COVID diagnosis, 79 pts (58%) had metastatic/active cancer and 56 pts (41%) were considered in remission/treated with curative intent. The diagnosis of SARS-CoV-2 infection was made by RT-PCR or thoracic CT scan alone in 93.4% and 6.6% of the cases, respectively. The majority of the pts was hospitalized (75%) and treated with HCQ/AZI (40; 30%) with inclusion in the ONCOVID trial (EudraCT: 2020-01250-21), IL-6 inhibitor (10), antiviral (6) or steroids (13). Fifteen pts were admitted in ICU (11%). Clinical deterioration occurred in 34 pts (24.8%) and was associated with hematological underlying disease, CRP at diagnosis of COVID19 >50 and the use of cytotoxic chemotherapy within <3mo. At data cut-off (April, 20th 2020), 95 (69.3%), 20 (14.6%), and 22 (16.1%) pts were discharged, had died, or were still hospitalized, respectively. All the deaths were considered related to the SARS-CoV-2 infection.
Conclusions: Globally, the rate of the SARS-CoV-2 infection in our cancer patients’ population does not seem to be higher compared to the global population. We have not found evidence that COVID19 is more lethal or aggressive in cancer patients that underwent usual SARS-Cov-2 treatment. We believe that adequate testing and protective measures, along with the low rate of SARS-cov-2-treatment-related adverse events (5.5%), justify an optimal management of the cancer patients’ underlying tumor.

Abstract
The present study was a review of cases of central cystadenocarcinoma over the past 29 years and provides clinical, radiological, and pathological information about these rare lesions. Six cases of central cystadenocarcinoma treated between 1991 and 2019 at Peking University Hospital of Stomatology in Beijing, China, were retrospectively analysed. A comprehensive review of clinical records was summarised and the histological diagnosis was revised using the 2017 World Health Organization criteria. The mean age of patients with central cystadenocarcinoma was 63 (range 51-75) years, and the male:female ratio 1:1. The clinical signs included localised swelling, pain, lower lip numbness, and trismus. There were more cases in the mandible than in the maxilla. All lesions were unilocular or multilocular in radiolucent regions with or without clear margins. The preferred treatment of central cystadenocarcinoma was surgical excision with wide margins, and no local recurrence was found during follow-up. Central cystadenocarcinoma often occurred in middle-aged or elderly patients. Because cystadenocarcinoma is somewhat rare, metastatic tumours of the jaw should be considered when diagnosing cystadenocarcinoma.

Abstract
Objective: To compare clinical characteristics and prognosis between patients with primary (PTL) and secondary thyroid lymphoma (STL) . Methods: A retrospective analysis was performed on 46 patients with thyroid lymphoma (PTL 19, STL 27) from January 2002 to October 2018. Results: ①PTL group included 4 males and 15 females, with a median age of 57 years. The STL group included 10 males and 17 females, with a median age of 61 years. Diffuse large B-cell lymphoma (DLBCL) was the main pathological subtype in both PTL and STL groups, with 14 cases (73.7%) and 20 cases (74.1%) respectively. In terms of clinical manifestations, goiter was the most common symptom in PTL patients 100.0% (19/19) , while 29.6% (8/27) STL had goiter (P<0.001) . The incidences of increased thyroglobulin antibody (TRAb) /thyroid peroxidase antibody (TPO) were 81.3% (13/16) in PTL group and 43.8% (7/16) in STL group (P=0.028) respectively. Concerning the clinical features of patients, only two PTL patients (10.5%) with advanced Ann Arbor stage (Ⅲ/Ⅳ) , while 21 (77.8%) STL experienced advanced Ann Arbor stage (P<0.001) . Elevated serum β(2)-MG were appeared in 1 (7.1%) PTL and 9 (47.4%) STL patients (P=0.013) , and advanced IPI score (3-5) was more common in STL than PTL (59.3% vs 5.3%, P<0.001) . ②Among the 17 PTL patients who received treatments, 15 (88.2%) achieved remission; as for STL patients received treatments, 23/25 (92.0%) were in remission. The 5-year overall survival (OS) rates of PTL (n=17) and STL groups (n=25) were (87.4±8.4) % and (70.0±13.1) % (P=0.433) respectively. ③The 5-year OS rate in 41 patients with B-cell thyroid lymphoma was (81.1±7.5) %. Univariate analysis showed that IPI score of 3-5 (P=0.040) and high level of serum IL-8 (P=0.022) were significantly associated with poor outcome. Conclusion: DLBCL was the most common subtype in both PTL and STL, and goiter was the major symptom in PTL. IPI score of 3-5 and high level of serum IL-8 were unfavorable prognostic factors for patients with B-cell thyroid lymphoma.

Abstract
BACKGROUND The causal link between elevated systemic inflammation biomarkers and poor survival has been demonstrated in cancer patients. However, the evidence for this correlation in endometrial cancer (EC) is too weak to influence current criteria of risk assessment. Here, we examined the role of inflammatory indicators as a tool to identify EC patients at higher risk of death in a retrospective observational study. METHODS A total of 155 patients surgically diagnosed with EC stage I-III FIGO 2009 and treated with postoperative External Beam Radiotherapy (EBRT) ± brachytherapy and chemotherapy according to ESMO-ESTRO-ESGO recommendation for patients at high risk of recurrence at the Gustave Roussy Institut, France, and Hospital Clínic, Spain, between 2008 and 2017 were evaluated. The impact of pre-treatment Neutrophil-to-Lymphocyte Ratio (NLR ≥ 2.2), Monocyte-to-Lymphocyte Ratio (MLR ≥ 0.18), Systemic Immune-Inflammatory Index (SII ≥ 1100) and lymphopenia (<1.0×109/L) on overall survival (OS), cancer-specific survival and progression-free survival was evaluated. Subsequently, a cohort of 142 patients within high-advanced risk groups according to ESMO-ESGO-ESTRO classification was evaluated. RESULTS On univariate analysis, NLR (HR = 2.2, IC 95% 1.1-4.7), SII (HR = 2.2, IC 95% 1.1-4.6), MLR (HR = 5.0, IC 95% 1.1-20.8) and lymphopenia (HR = 3.8, IC 95% 1.6-9.0) were associated with decreased OS. On multivariate analysis, NLR, MLR, SII and lymphopenia proved to be independent unfavorable prognostic factors. CONCLUSIONS lymphopenia and lymphocytes-related ratio are associated with poorer outcome in surgically staged I-III FIGO EC patients classified as high risk and treated with adjuvant EBRT and could be considered at cancer diagnosis. External validation in an independent cohort is required before implementation for patients' stratification.
