Abstract
Objective: To explore the clinical value of mismatch negativity and P3a combined with electroencephalogram (EEG) reactivity to predict the prognosis of patients after severe brain injury. Methods: The clinical data of patients with severe brain injury who were admitted to the neurosurgical intensive care unit of Xiangya Hospital of Central South University from October 2019 to July 2020 were retrospectively analyzed. All patients underwent evaluation of auditory mismatch negativity (MMN), P3a, and EEG reactivity (EEG-R) within 28 days after the onset of coma. Patients were divided into two groups using the 3-month Glasgow Outcome Scale (GOS) after coma onset, a GOS score of 3-5 was defined as a favorable outcome, and GOS grades 1-2 were defined as an unfavorable outcome. The correlation between clinical indicators and prognosis was analyzed, and the predictive values of statistically significant indicators and the cut-off values were determined using the receiver operating characteristic (ROC) curve. Results: A total of 48 patients were enrolled in the study, including 35 males and 13 females (age range:18-68 years old). Twenty-nine of the patients had a favorable outcome and 19 had an unfavorable outcome. The Glasgow Coma Scale (GCS), EEG-R, absolute amplitude of MMN at Fz (FzMMNA), and amplitude of P3a at Cz (CzP3aA) were significantly correlated with the prognosis of comatose patients (P<0.001). Multivariate logistic regression analysis revealed that only EEG-R, FzMMNA, and CzP3aA were independent predictors for the prognosis of comatose patients after severe brain injury (all P<0.05), with the area under the curve (AUC) of 0.757 (0.613-0.900), 0.912 (0.830-0.994) and 0.887 (0.793-0.981), respectively. The combination of FzMMNA and CzP3aA and the combinationof EEG-R, FzMMNA and CzP3aA increased the value of AUC to 0.942 (0.879-1.000) and 0.964 (0.920-1.000), respectively. Moreover, a cut-off value of 1.27 μV and 2.64 μV for FzMMNA and CzP3aA, respectively, yielded the best sensitivity and specificity for the prognosis prediction of patients with severe brain injury [FzMMNA: 89.66%(26/29) and 84.21%(16/19); CzP3aA:82.76%(24/29) and 84.21%(16/19)]. Conclusion: This study indicates that the combination of EEG-R, FzMMNA, and CzP3aA may serve as a favorable prognostic indicator for comatose patients after severe brain injury.

Abstract
Ductal origin of distal pulmonary artery (DODPA) is a rare congenital cardiovascular anomaly, with an incidence of approximately 1 in 200 000 people. It involves the proximal interruption of one pulmonary artery branch, with the distal part arising from the base of the brachiocephalic artery, via the ipsilateral ductus arteriosus (DA) and the intrapulmonary branch of the pulmonary artery is usually intact. If timely treatment is not provided after birth, it is very likely that, due to DA closure, severe hypoplasia will occur in the lung supplied by the abnormal pulmonary artery. Hence, prenatal diagnosis of DODPA is important to enable initiation of prostaglandin treatment and early rehabilitation of the affected lung. Herein, we report three cases of fetal DODPA diagnosed via two-dimensional (2D) ultrasonography combined with four-dimensional (4D) spatiotemporal image correlation. We also present a literature review, and explore the ultrasonographic findings and the importance of 2D and 4D ultrasonography in obtaining an accurate prenatal diagnosis of DODPA. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
This Letter reports the first measurement of high-energy reactor antineutrinos at Daya Bay, with nearly 9000 inverse beta decay candidates in the prompt energy region of 8-12 MeV observed over 1958 days of data collection. A multivariate analysis is used to separate 2500 signal events from background statistically. The hypothesis of no reactor antineutrinos with neutrino energy above 10 MeV is rejected with a significance of 6.2 standard deviations. A 29% antineutrino flux deficit in the prompt energy region of 8-11 MeV is observed compared to a recent model prediction. We provide the unfolded antineutrino spectrum above 7 MeV as a data-based reference for other experiments. This result provides the first direct observation of the production of antineutrinos from several high-Q_{β} isotopes in commercial reactors.

Abstract
AIM To explore the value of preoperative contrast-enhanced computed tomography (CT) tumour texture characteristics, and clinical and laboratory parameters on the prognosis of curative resection for non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS This retrospective study included 64 patients (34 men and 30 women) with NSCLC who underwent curative resection and were then followed up for 5 years or until death. Preoperative contrast-enhanced CT images, clinical features, and laboratory parameters were collected for these patients. CT texture features of the primary tumour before surgery were extracted from the contrast-enhanced CT images using ImageJ software. Based on the cut-off values determined by X-tile software, the preoperative CT texture features, clinical features, and laboratory parameters were divided into two groups. Kaplan-Meier survival curves and log-rank tests were used to compare the 5-year overall survival (OS) of patients. Multivariate Cox regression analysis was used to determine the independent factors influencing the prognosis. RESULTS The mean survival was 51.5 months. Tumour volume, entropy, platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), and albumin-to-globulin ratio (AGR) were shown to be significantly associated with 5-year OS (p<0.05). Multivariate Cox regression analysis revealed that entropy was the independent factor of prognosis (hazard ratio 4.375, 95% confidence interval [CI]: 1.646-11.620, p=0.003). CONCLUSION Entropy is an important and potentially non-invasive imaging biomarker for predicting the prognosis of NSCLC undergoing curative resection.

Abstract
BACKGROUND No standard of care for mucosal melanoma (MM) in the adjuvant setting has been established. Meanwhile, relapse-free survival (RFS) is only about five months after surgery alone. This phase II trial aimed to compare toripalimab vs. high-dose interferon-α2b (HDI) as an adjuvant therapy for resected MM. PATIENTS AND METHODS From July 2017 to May 2019, 145 patients with resected MM were randomized (1:1) to receive HDI (N = 72) or toripalimab (N = 73) for one year until disease relapse/distant metastasis, unacceptable toxicity, or withdrawal of consent. The primary endpoint was RFS. The secondary endpoints included distant metastasis-free survival (DMFS), overall survival (OS), and safety. RESULTS After a median follow-up of 26.3 months, the numbers of RFS, OS, and DMFS events were 51 vs. 46, 33 vs. 29, and 49 vs. 44 in the toripalimab arm and the HDI arm, respectively. The median RFS were 13.6 (95%CI: 8.31-19.02) months and 13.9 (95%CI: 8.28-19.61) months in the toripalimab arm and HDI arm, respectively. The DMFS was not significantly different between the two arms (HR: 1.00, 95%CI: 0.65-1.54). The median OS was 35.1 months (95%CI: 27.93-NR) in the toripalimab arm, with no significant difference in all-cause death (HR: 1.11, 95% CI: 0.66-1.84) for the two arms. The median sums of the patients' actual infusion doses were 3672 mg and 1054.5 MIU in the toripalimab arm and HDI arm, respectively. The incidence of treatment-emergent adverse events with a grade ≥ 3 was much higher in the HDI arm than in the toripalimab arm (87.5% vs. 27.4%). CONCLUSION Toripalimab showed a similar RFS and a more favorable safety profile than HDI, both better than historical data, suggesting that toripalimab might be the better treatment option. However, additional translational studies and better treatment regimens are still warranted to improve the clinical outcome of MM.

Abstract
Abstract
Study question
The impact of endometriosis on the outcomes of ART is still ambiguous and the mechanism by which endometriosis impacts fertility has not been fully elucidated
Summary answer
Endometriosis was associated with low CLBR in IVF, which might be due to the change of follicular microenvironment and compromising the quality of embryos.
What is known already
Despite the great advantages of IVF treatment in endometriosis-linked infertility, the impact of endometriosis on outcomes of infertility management with ART is controversial and few studies focused on the association between endometriosis and CLBR. Numerous mechanisms have been proposed in an effort to delineate the multifaceted pathophysiology that induces impairment of reproductive dynamics in patients with endometriosis. Reactive oxygen species, dysregulation of the immune system and cellular architectural disruption constitute the crucial mechanisms that detrimentally affect oocyte and embryo developmental potential.
Study design, size, duration
This study retrospectively included 433 patients with endometriosis and 1299 patients with tuber factor infertility to evaluate the impact of endometriosis on IVF pregnancy outcome between January 2016 and December 2018.The basic study prospectively recruited 30 patients with ovarian endometriosis and 35 controls with tubal factor infertility to analyze polarization stage of macrophages in their follicular fluid, and another 20 females with ovarian endometriosis and 30 controls to detect cytokines in their FF.
Participants/materials, setting, methods
Data on all women undergoing fresh or frozen IVF treatment cycles were analysed to compare the CLBR between endometriosis and tuber factor infertility patients. A cytometry panel of 4 antibodies (CD45, CD3, CD80, CD163) was designed to enumerate the numbers of MI and MII macrophages from the cell sediment from FF samples. Quantibody® array was utilized to determine the concentration of 10 cytokines in FF, including IFN-γ, IL-1α, IL-1β, IL-10,IL-13,IL-4, IL-6, IL-8, MCP-1 and TNF-α.
Main results and the role of chance
The results showed that patients with endometriosis were associated with noticeably fewer retrievable oocytes, a lower oocyte maturity rate, decreased numbers of available and high-quality embryos (all p < 0.001) in comparison with the control group. The clinical pregnancy and live birth rate of the endometriosis group were lower in the frozen-thawed embryo transfer cycles (p = 0.028 and p = 0.008, respectively), which leading to a declined cumulative live birth rate (CLBR) (p = 0.001). Logistic regression analysis indicated a close association between endometriosis and low CLBR (p = 0.002). Furthermore, the numbers of type I and type II macrophages in follicular fluid (FF) of patients with ovarian endometriosis were significantly increased compared with the control group (p < 0.001). The expressions of IL-1α, IL-1β, TNF-α, IL-6, IL-13, and IL-10 in FF were higher in endometrioma group(p < 0.05). The increased expression of cytokines was negatively correlated with embryo outcomes, including the numbers of total oocytes retrieved, mature oocytes, and fertilized oocytes, and the numbers of high-quality blastocysts and embryos. Additionally, IL-6 and IL-8 were positively correlated with AMH, rate of available blastocysts, number of blastocysts formed and available blastocysts, but were negatively associated with rate of MII oocytes.
Limitations, reasons for caution
The present study being of a retrospective and monocentric study, may not come to a very convincing conclusion, and some unknown biases might still exist due to possible underestimation of some confounders.
Wider implications of the findings
Collectively, our results indicate that endometriosis does adversely affect pregnancy outcomes of ART, as women with endometriosis produce a lower quantity of oocytes and embryos. Moreover, endometriosis might play a role in oocyte or embryo outcomes via regulating the production of cytokines or the number of immune cells in FF.

Abstract
OBJECTIVE We aimed to systematically review the impact of local estrogen use in combination with a pessary on vaginal complications in postmenopausal women with pelvic organ prolapse (POP). METHODS We searched databases including Medline, Embase, PubMed, Clinical Trials and the Cochrane Central Register of Controlled Trials for relevant literature published in English from inception to 31 May 2021. Only randomized controlled trials (RCTs) and cohort studies were included. RESULTS In total, five studies were included (three RCTs, one prospective study and one retrospective cohort study). The meta-analysis was performed with subgroups. Our results indicated a significantly lower incidence of bacterial vaginosis (BV) among postmenopausal women who used estrogen than among controls, with a total pooled odds ratio (OR) of 0.29 (95% confidence interval [CI]: 0.11-0.72; I2 = 38%; p = 0.008). The summary ORs of the estrogen use group were 0.98 (95% CI: 0.59-1.63; I2 = 41%; p = 0.95) for vaginal ulceration, 0.80 (95% CI: 0.42-1.54; I2 = 29%; p = 0.50) for vaginal bleeding and 0.74 (95% CI: 0.35-1.58; I2 = 35%; p = 0.44) for vaginal discharge. CONCLUSIONS Local estrogen in combination with a pessary could decrease the BV rate among postmenopausal women with POP. However, consensus regarding the value of estrogen use for decreasing other pessary complications has not yet been reached. Additional multicenter RCTs with large sample sizes should be conducted to better understand the effect of estrogen use on reducing pessary-related complications.

Abstract
Objective: To understand the incidence of pneumoconiosis in the non-coal mining industry in Jiangsu Province, and provide reference for the prevention and control of pneumoconiosis in the non-coal mining industry. Methods: The data of 7019 newly diagnosed pneumoconiosis patients in non-coal mining industry in Jiangsu Province from January 1956 to December 2019 were collected through the Jiangsu Province Pneumoconiosis Follow-up Network Report System, including the gender of the pneumoconiosis patients, the name of the employer and the location, the industry classification of the employer, the duration of dust exposure in dust exposure, the name of occupational pneumoconiosis disease, the date of diagnosis of pneumoconiosis, etc. The collected case data of patients with pneumoconiosis were entered into the statistical software, and the characteristics of the patients' diagnosis time, region and industry were analyzed. Results: The number of confirmed pneumoconiosis patients in the non-coal mining industry in Jiangsu Province was mostly in 2007 (395 cases) , concentrated in Wuxi City (40.96%, 2875/7019) and Suzhou City (27.72%, 1946/7019) . The industries to which the patients belonged were mainly non-metallic mining and dressing (60.95%, 4278/7019) , and the most common type of pneumoconiosis was silicosis (96.40%, 6766/7019) . The patients were mainly stageⅠpneumoconiosis (61.33%, 4305/7019) . There were statistically significant differences in the mean age of diagnosis and the average duration of dust exposure among patients with different pneumoconiosis stages (P<0.01) . The differences in the average diagnosis age and the average duration of dust exposure of patients with different types of pneumoconiosis were statistically significant (P<0.05) , the mean age of diagnosis and the average duration of dust exposure of electric welders were the smallest, which were (44.92±7.74) years old and (17.38±10.15) years, respectively. Conclusion: The regional and industry distribution characteristics of new pneumoconiosis patients in the non-coal mining industry in Jiangsu Province are obvious, and attention should be paid to the treatment of pneumoconiosis patients with young diagnosed age and short duration of dust exposure, as well as the personal protection and health protection of front-line workers such as electric welders who are exposed to productive dust in a short period of time.

Abstract
Objective: To explore the feasibility and perioperative safety of transoral robotic surgery with da Vinci Xi platform for pharyngolaryngeal tumors. Methods: A retrospective analysis was performed on 55 consecutive cases with resection of pharyngolaryngeal tumors by transoral robotic surgery with da Vinci Xi platform from July 27, 2020 to October 31, 2021 in the Department of Head and Neck Surgery, Fudan University Eye, Ear, Nose and Throat Hospital, including 44 males and 11 females, aged 25-79 years. There were 41 cases of oropharyngeal tumors, 9 cases of parapharyngeal space tumors, 2 cases of laryngeal tumors, 2 cases of hypopharyngeal tumors and 1 case of retropharyngeal space tumor. Operative time, intraoperative blood loss, postoperative hospital stay, perioperative tracheotomy, nasal feeding, hemorrhage and other complications were analyzed. Results: Of the 55 patients, 54 received resection of pharyngolaryngeal tumors by da Vinci robot through oral approach, and only 1 case of pyriform sinus carcinoma underwent a conversion to open surgery due to poor exposure of lower margin. The average surgical time for the patients with transoral robotic surgeries was 64.4 min, the average blood loss was 24.8 ml, the average postoperative hospital stay was 6.9 d, and the average oral feeding time was 11.1 d. Seventeen patients (30.9%) underwent preventive tracheotomy during surgery. Among 38 cases of laryngeal cancer, 28 underwent simultaneously neck dissection. No serious complications occurred in all patients during and after operation. The follow-up time was 1-15 months. Aside from 1 patient had a relapse 10 months after surgery, other patients had no recurrence or metastasis. Conclusion: Transoral robotic surgery with da Vinci Xi is safe, effective and minimally invasive for resection of pharyngolaryngeal tumors under reasonable indications.

Abstract
Realizing quantum speedup for practically relevant, computationally hard problems is a central challenge in quantum information science. Using Rydberg atom arrays with up to 289 qubits in two spatial dimensions, we experimentally investigate quantum algorithms for solving the Maximum Independent Set problem. We use a hardware-efficient encoding associated with Rydberg blockade, realize closed-loop optimization to test several variational algorithms, and subsequently apply them to systematically explore a class of graphs with programmable connectivity. We find the problem hardness is controlled by the solution degeneracy and number of local minima, and experimentally benchmark the quantum algorithm's performance against classical simulated annealing. On the hardest graphs, we observe a superlinear quantum speedup in finding exact solutions in the deep circuit regime and analyze its origins.

Abstract
Objective: This study aimed to investigate the clinical and prognostic significance of TET2 single nucleotide polymorphism I1762V in patients with acute myeloid leukemia (AML) . Methods: The high-throughput sequencing method was used to sequence 58 hematological tumor-related genes in bone marrow samples from 413 patients with AML. TET2 I1762V and other somatic mutations were annotated and compared with patients' clinical information and prognosis. Results: I1762V was found in 154 patients with AML, which was significantly different from the general population in NyuWa Chinese Population Variant Database (χ(2)=72.4, P<0.001) . I1762V was not related to sex, age, and karyotype of patients with AML (P>0.05) . Patients with I1762V had a significantly higher proportion of NPM1 and KIT gene mutations than others (P<0.001) . NPM1 and KIT mutations were mutually exclusive. The survival analysis results revealed that the overall survival (OS) and progression-free survival (PFS) of patients with AML with I1762V were significantly greater than those of wild-type patients (HR=0.57, P=0.030; HR=0.55, P=0.020) , whereas the OS and PFS in patients with AML with DNMT3A mutation (with or without I1762V mutation) were lower than those of wild-type patients (HR=1.79, P=0.030; HR=1.74, P=0.040) . Conclusion: TET2 SNP I1762V has been linked to AML. I1762V is a prognostic factor of patients with AML, which can be used to guide the treatment and evaluate the prognosis of AML.

Abstract
Objective: To understand the characteristics and trend of the premature death rate of 4 major chronic diseases in Ji'nan from 2015 to 2020. Methods: The death cause surveillance data and population data during 2015-2020 in Ji'nan were collected, and abbreviated life table, Joinpoint regression analysis and other methods were used to analyze the characteristics and change trends of the premature death rates of 4 major chronic diseases. Results: The crude mortality rate and age standardized mortality rate changes for the 4 major chronic diseases from 2015 to 2020 range from 568.65/100 000 to 604.06/100 000 and 366.77/100 000 to 432.48/100 000, respectively. The annual premature death rate of 4 major chronic diseases declined by 3.33% averagely from 2015 to 2020 (95%CI: -6.25%--0.32%), which might be explained by the declines of the premature death rates of cardiovascular and cerebrovascular diseases [average annual percentage change (AAPC)=-3.23%, 95%CI: -6.32%--0.05%] and cancer (AAPC=-3.58%,95%CI:-6.83%--0.21%). The average decline rate in women (AAPC=-4.19%,95%CI:-7.56%- -0.70%) was higher than that in men (AAPC=-2.92%,95%CI: -5.65%--0.11%). Conclusions: The premature death rate of 4 major chronic diseases showed a downward trend in Ji'nan from 2015 to 2020. Men should be considered as a key population in the prevention and control of 4 major chronic diseases, and attention should also be paid to the non-significant declines in the premature death rates of chronic respiratory diseases and diabetes.

Abstract
A joint determination of the reactor antineutrino spectra resulting from the fission of ^{235}U and ^{239}Pu has been carried out by the Daya Bay and PROSPECT Collaborations. This Letter reports the level of consistency of ^{235}U spectrum measurements from the two experiments and presents new results from a joint analysis of both data sets. The measurements are found to be consistent. The combined analysis reduces the degeneracy between the dominant ^{235}U and ^{239}Pu isotopes and improves the uncertainty of the ^{235}U spectral shape to about 3%. The ^{235}U and ^{239}Pu antineutrino energy spectra are unfolded from the jointly deconvolved reactor spectra using the Wiener-SVD unfolding method, providing a data-based reference for other reactor antineutrino experiments and other applications. This is the first measurement of the ^{235}U and ^{239}Pu spectra based on the combination of experiments at low- and highly enriched uranium reactors.

Abstract
Artificial liver is one of the effective methods to treat liver failure. Patients with liver failure are critically ill and have great individualized differences. Therefore, the specific program for the treatment of liver failure with artificial liver should be individualized. The commonly used non-biological artificial liver models include simple plasmapheresis, double filtration plasmapheresis, plasma filtration with dialysis, double plasma molecular adsorption system, molecular absorbent recirculating system, hemodiafiltration, continuous venovenous hemodiafiltration, hybrid, etc. The curative effect should be properly judged from patient's symptoms, laboratory test indicators, survival rate and other aspects after artificial liver therapy.

Abstract
Objective: To study the clinicopathological and genetic features of natural killer (NK)-cell enteropathy for better understanding of this rare disease and prevention of its misdiagnosis. Methods: Two cases of NK-cell enteropathy were diagnosed in the First Affiliated Hospital of Zhengzhou University, China from October 2017 to February 2021. The clinical characteristics, morphology, immunohistochemistry, Epstein-Barr virus-encoded RNA (EBER) in situ hybridization and T cell receptor gene rearrangement were analyzed. The patients were followed up by a telephone interview. Results: The patients were both male, aged 40 and 28 years, respectively. Both patients were admitted to the hospital for an annual checkup without obvious gastrointestinal symptoms. The endoscopy showed that the gastric body of case 1 had a mucosal bulge, small area of congestion and erosion, while the rectum of case 2 had congestion and erosion. Microscopically, the lesions of the 2 cases were relatively limited. Many lymphoid cells infiltrated within the lamina propria of the mucosa and into the muscularis mucosa in case 2. In case 1, the glands were reduced in the lesion, and the glandular cavity was slightly compressed and deformed. There was no infiltration or destruction of the glands in either case. Lymphoid cells were atypical, with medium-to-large cell sizes. Their cytoplasm was medium-to-slightly abundant and appeared eosinophilic or translucent. In case 2, characteristic eosinophilic granules were seen in the cytoplasm of a few cells. The nuclei in both cases were round, oval and irregular, with fine chromatin, inconspicuous nucleoli, and no mitotic figures were noted. Necrosis was seen in case 1 while both cases had no central growth or destruction of blood vessels. Immunophenotyping showed that CD56, granzyme B and TIA-1 were positive in both cases, part of the cells was CD3-positive, and some cells were weakly CD4-positive in case 2. The CD5, CD8, CD30, ALK and B-lineage markers (CD20, CD79α) were all negative. The Ki-67 proliferation index was about 60% and 30%, respectively. Both cases were EBER negative. TCR gene rearrangement was polyclonal. Follow-up showed that none of the 2 patients had any special treatments and stayed well. Conclusions: NK-cell enteropathy is rare, with biological behaviors similar to benign tumors, and occasional recurrence. Its histology and immunophenotype are easily confused with NK/T cell-derived lymphomas. Combination of its unique endoscopic features, EBER negativity, polyclonal TCR gene rearrangement and good prognosis can confirm the diagnosis and avoid misdiagnosis and overtreatment.

Abstract
Objective: To investigate the survival outcomes and prognostic factors of patients with salvage surgery for hypopharyngeal carcinoma after radiotherapy. Methods: A retrospective analysis was performed, including 26 patients treated in Ningbo Medical Center Lihuili Hospital between January 2010 and December 2015. All patients were males, aged 48-83 years, of whom 8 cases were local residual after radiotherapy alone, 8 cases were local recurrence after postoperative radiotherapy, 2 cases were residual of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after radiotherapy alone, 2 cases were recurrence of cervical lymph nodes after postoperative radiotherapy and 4 cases were recurrence of tracheal stoma. The salvage operations included: local resection, local resection with neck dissection, simple neck dissection, tumor resection of tracheostomy, and additional repair according to the defect. Chi square test was used for recurrence and metastasis analysis, Kaplan-Meier method for survival analysis, Log-rank test for univariate analysis, and Cox regression model for multivariate analysis. Results: The complication rate of salvage surgery was 23.1% (6/26). The recurrence rate was 65.4% (17/26) and the distant metastasis rate was 42.3% (11/26) in the 5-year follow-up after salvage surgery. Patient's age and tumor invasion extent were correlated with recurrence. Initial treatment, tumor persistence or recurrence after radiotherapy, recurrence location and tumor invasion extent were correlated with distant metastasis (all P<0.05). Overall, 3 year and 5 year survival rates were 42.3% and 23.1% respectively. Age, recurrence location, surgical margin and tumor invasion extent were related to prognosis (χ²=6.56, 10.68, 9.32, and 7.90 respectively, all P<0.05). Multivariate analysis showed that surgical margin and tumor invasion extent were independent risk factors for prognosis (OR (95%CI) = 3.19 (1.03-9.84), 14.37 (2.46-84.08), both P<0.05). Conclusion: Salvage surgery is the first choice for patients with recurrence after radiotherapy for hypopharyngeal carcinoma. Safe surgical margin should be ensured, especially in tumors invading muscle, bone tissue or lymph node capsule.
