Abstract
BACKGROUND Standardized and transparent reporting of surgical technique is the cornerstone of effective dissemination, implementation and improvement. However, current reporting of surgical techniques is inadequate. The existing guidelines potentially applied to guide surgical technique reporting are with a minimal highlight of the surgical technique, lack requirements explaining what extent and dimensions need to be described in detail, or are unlikely to extrapolate to a wide range of surgical techniques. This study aims to formulate a rigorous protocol to develop a surgical technique reporting checklist and standards (SUPER) that defines what a clear, comprehensive and detailed surgical technique report should be contained. METHODS This protocol is designed following the classic guidance for developing reporting guidelines recommended by the EQUATOR network. RESULTS The development team will consist of surgeons (~80%), methodologists, and journal editors. The draft checklist sources will include a scoping review of existing reporting guidelines related to surgical technique, surgical technique articles from 15 top journals published in the last year, and brainstorming by the multidisciplinary development team. The final SUPER checklist will be formed after three rounds of Delphi surveys, one round of face-to-face meeting, and a month-long pilot test. The SUPER checklist will be published as open-access and be used in combination with existing reporting guidelines related to surgical techniques (e.g., IDEAL). This protocol will steer the SUPER checklist's development, allowing us to further elaborate surgical technique reporting for all surgical specialties, and enabling a more favorable experience for surgeons, nurses, medical students, residents, editors, and reviewers. TRIAL REGISTRATION This trial is registered at the EQUATOR network on December 18th, 2020.

Abstract
Background: In 1995, a clinical randomized controlled study (RCT) conducted by the Lung Cancer Study Group (LCSG) pointed out that the lobectomy was the gold standard for treating early lung cancer. However, with the development of technology, the results of several retrospective studies have shown that the efficacy of pulmonary segmentectomy is equivalent to that of lobectomy. Currently, it is still controversial whether segmental resection or lobectomy should be performed for early lung cancer. Thus, we aim to summarize the indications of segmentectomy. Methods: To conduct the review, previous researches involving indications of segmentectomy were collected from the literature using Pubmed. These articles were published and accepted in English in the medical literature from 2013 to 2020. We have focused on segmentectomy and its indications. Results: A total of 176 articles were retrieved from the Pubmed database, of which 31 articles included indications for segmentectomy. We summarized the relevant content, and the potential and prospect of segmentectomy for the treatment of lung cancer were emphasized. Conclusions: These findings have a number of important implications for future practice. Pulmonary segmentectomy is a very vital surgical procedure for select patients with lung cancer, which provides a novel approach for the treatment of lung cancer and the survival of lung cancer patients.

Abstract
OBJECTIVE Cancer susceptibility 19 (CASC19), a crucial lncRNA associated with multiple cancers, has been reported to play a vital role in the progression of human malignant tumors. However, the underlying mechanism of CASC19 in pancreatic cancer (PC) was still unknown. The purpose of this study was to explore the biological and clinical significance of CASC19 in PC. PATIENTS AND METHODS RT-qPCR assay was adopted to analyze CASC19 expression in PC tissues and cell lines. Furthermore, the correlation between the CASC19 level and the survival rate of PC patients was assessed by Kaplan-Meier analysis. Bioinformatics analysis and Luciferase reporter assay were utilized to confirm the interaction between miR-148b and CASC19 or E2F7. Cell viability, migration, invasion, and apoptosis were analyzed using MTT, transwell, and TUNEL assays. RESULTS The results elucidated that CASC19 expression was markedly increased in PC tissues and cell lines. Patients with high expression of CASC19 had a short survival time. Silencing of CASC19 attenuated PC cell proliferation, migration, and invasion. Moreover, we identified that miR-148b was a target of CASC19. CASC19 was negatively correlated with miR-148b and positively correlated with E2F7. The inhibitory effect of CASC19 knockdown on the progression of PC was reversed by the down-regulation of miR-148b or up-regulation of E2F7. CONCLUSIONS These results demonstrated that CASC19 participated in the development of PC. The CASC19/miR-148b/E2F7 axis might be a new study direction for PC treatment.

Abstract
Objective: To discuss the new idea of on-the-spot recompression treatment and multidisciplinary treatment (MDT) for patients with unstable vital signs of type II decompression sickness. To provide reference for the nearby treatment of patients with critical decompression sickness. Methods: The clinical data of a case of a multi-disciplinary collaborative treatment of type II decompression sickness complicated with multiple organ dysfunction syndrome (MODS) admitted to a third-class A hospital in January 2020 were analyzed and summarized. Results: The patient suffered from consciousness disturbance and shock after 3 min of diver's blow-up out of the water. CT examination showed gas accumulation in the systemic multi-organ venous system, and laboratory examination suggested MODS. The oxygen inhalation regimen was given in the session of recompression treatmen by 0.12-0.18 MPa. Intravenous fluid was the total of 8900 ml in the session, and the total recompression treatment time was 9 h 45 min. The patient was still in unconscious when he finished the session. CT re-examination confirmed the elimination of venous bubbles, and laboratory examination indicated multiple organ failure (MOF) . The patient was given comprehensive supporting treatment by mechanical assisted breathing and following by continuons renal replacement therapy (CRRT) and extrocorporeal membrane oxygenation (ECMO) in the intensive care unit, and was discharged after 32 d of hospitalization. Conclusion: Critical decompression sickness patients with unstable vital signs are taken to a local general hospital with hyperbaric oxygen chamber and intensive care unit. The successful treatment can be achieved by organizing diving medicine, hyperbaric oxygen medicine and critical medical personnel for MDT.

Abstract
Immune checkpoint blockade (ICB) has become a standard treatment for non-small cell lung cancer (NSCLC). However, most patients with NSCLC do not benefit from these treatments. Abnormal vasculature is a hallmark of solid tumors and is involved in tumor immune escape. These abnormalities stem from the increase in the expression of pro-angiogenic factors, which is involved in the regulation of the function and migration of immune cells. Anti-angiogenic agents can normalize blood vessels, and thus transforming the tumor microenvironment from immunosuppressive to immune-supportive by increasing the infiltration and activation of immune cells. Therefore, the combination of immunotherapy with anti-angiogenesis is a promising strategy for cancer treatment. Here, we outline the current understanding of the mechanisms of vascular endothelial growth factor/vascular endothelial growth factor receptor (VEGF/VEGFR) signaling in tumor immune escape and progression, and summarize the preclinical studies and current clinical data of the combination of ICB and anti-angiogenic drugs in the treatment of advanced NSCLC.

Abstract
Background: Timing for intervention of small indeterminate pulmonary nodules has long been a topic of debate given the low incidence of malignancy and difficulty in obtaining a definite preoperative diagnosis. We sought to determine survival outcomes of surgical and non-surgical managements in non-small cell lung cancer (NSCLC) ≤8 mm, which may provide a reference for prospective decision-making for patients with suspected NSCLC. Method: A total of 1,652 patients with Stage IA NSCLC ≤8 mm were identified from the Surveillance, Epidemiology, and End Results (SEER) database and categorized into surgery and non-surgery groups. Chi-square test, t-test and Mann-Whitney U test were used to compare the baseline characteristics between groups. Survival curves were depicted using Kaplan-Meier method and compared by log-rank test. Cox proportional hazard model was used for univariate and multivariate analyses. Adjustment of confounding factors between groups was performed by propensity score matching. Results: The surgery and non-surgery groups included 1,438 and 208 patients, respectively. Patients in surgery group demonstrated superior survival outcome than patients in non-surgery group both before [overall survival (OS): HR, 16.22; 95% CI, 11.48-22.91, p < 0.001; cancer-specific survival (CSS): HR, 49.6; 95% CI, 31.09-79.11, p < 0.001] and after (OS: HR, 3.12; 95% CI, 2.40-4.05, p < 0.001; CSS: HR, 3.85; 95% CI, 2.74-5.40, p < 0.001) propensity score matching. The 30-day mortality rates were 3.1 and 12.0% in surgery and non-surgery groups, respectively. Multivariate analysis suggested age, sex, race, tumor size, grade, pathological stage were all independent prognostic factors in patients with ≤8 mm NSCLC. A comparison of surgical resections revealed a survival superiority of lobectomy over sub-lobectomy. In terms of CSS, no statistically significant difference was found between segmentectomy and wedge resection. Conclusion: The current SEER database showed better prognosis of surgical resection than non-surgical treatment in patients with ≤8 mm NSCLC. However, the factors that should be essentially included in the proper propensity-matched analysis, such as comorbidity, cardiopulmonary function and performance status were unavailable and the true superiority or inferiority should be examined further by ongoing randomized trial, especially comparing surgery and stereotactic body irradiation.

Abstract
AIMS To develop an essential oil (EO)-loaded textile coating using an environmentally friendly microemulsion technique to achieve both antimicrobial and mosquito repellent functionalities. METHODS AND RESULTS Minimum inhibitory concentrations and fractional inhibitory concentrations of litsea, lemon and rosemary EOs were determined against Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Pseudomonas aeruginosa and Trichophyton rubrum. A 1 : 2 mixture of litsea and lemon EOs inhibited all the microorganisms tested and was incorporated into a chitosan-sodium alginate assembly by a microemulsification process. The EO-loaded microemulsions were applied to cotton and polyester fabrics using a soak-pad-dry method. The textile challenge tests demonstrated 7-8 log10 reductions of S. epidermidis, S. aureus and E. coli after 24 h and T. rubrum after 48 h. Aedes aegypti mosquito repellency was also assessed which demonstrated 71·43% repellency compared to 52·94% by neat EO-impregnated cotton. CONCLUSIONS Textiles treated with the litsea and lemon EO microemulsion showed strong antimicrobial activity against the skin associated microorganisms E. coli, S. aureus, S. epidermidis and T. rubrum and potential mosquito repellent properties. SIGNIFICANCE AND IMPACT OF THE STUDY EOs could be useful for the development of natural, environmentally friendly functional textiles to protect textiles and users from microbial contamination in addition to possessing other beneficial properties such as mosquito repellency.

Abstract
BACKGROUND To evaluate the benefits of perioperative pulmonary rehabilitation training (PPRT) in patients undergoing thoracoscopic lung cancer resection. METHODS The clinical data of 1,427 patients undergoing thoracoscopic lung cancer resection were collated. Of these patients, 779 received PPRT (the PPRT group), which included systematic education, improvement of posture, diaphragmatic respiration, bilateral lower thoracic expansion, surgical side thoracic local expansion, incentive spirometry training, effective cough training, aerobic walking, and other systematic pulmonary rehabilitation training. The other 648 patients did not receive PPRT (the non-PPRT group). Baseline characteristics including length of hospital stay, cost of hospitalization, and the incidence of postoperative pulmonary complications (PPCs) were assessed. RESULTS There was no significant difference between the PPRT group and the non- PPRT group in terms of age, gender distribution, tumor location, operation mode, postoperative pathological type, TNM stage, and other baseline characteristics (P>0.05). The complication index of the PPRT group was slightly higher than that of the non-PPRT group (P<0.05). Patients in the PPRT group had significantly fewer postoperative hospitalization days (PHD) {6.1 days [95% confidence interval (CI): 5.8 to 6.4] vs. 6.4 days (95% CI: 6.1 to 6.7), P=0.002}, fewer total hospitalization days (THD) [9.3 days (95% CI: 8.9 to 9.7) vs. 10.8 days (95% CI: 10.3 to 11.3), P=0.000], lower non-surgical expenses (35,024±9,742 vs. 36,831±10,245 RMB), and fewer cases of PPCs) (3.72% vs. 6.33%, P=0.016) compared to patients in the non-PPRT group. In the subgroup analysis, patients less than 60 years old in the PPRT group fared better in terms of the PHDs, total inpatient days, and non-surgical expenses compared to patients in the non-PPRT group (P<0.05). In patients aged 60 years and older, the THDs in the PPRT group was less than that in the non-PPRT group (P<0.05), but there were no significant differences in the PHDs and non-surgical expenses. CONCLUSIONS PPRT can reduce the cost of medical resources in patients undergoing thoracoscopic lung cancer resection, especially by shortening the length of hospital stay, reducing the cost of hospitalization, and reducing PPCs.

Abstract
Background There are few studies focused on comparing the toxicity, postoperative complication rate, and survival among patients with locally advanced esophageal squamous cell cancer receiving a different dose and intensity of vinorelbine plus cisplatin for neoadjuvant chemoradiotherapy (nCRT) followed by surgery. Methods In total, 78 patients diagnosed with locally advanced esophageal squamous cell cancer that had received a vinorelbine and cisplatin (VP)1 or VP2 regimen for nCRT followed by surgery in Taizhou Hospital of Zhejiang Province between June 2008 and December 2016 were retrospectively analyzed. The VP1 regimen involved cisplatin 75 mg/m2 on day 1, and vinorelbine 25 mg/m2 on days 1 and 8, for two cycles. The VP2 regimen involved cisplatin 25 mg/m2 on days 1 to 4, and vinorelbine 25 mg/m2 on days 1 and 8, for two cycles. The rate of adverse events, postoperative complications, and survival were compared between the two groups. Results The median overall survival (OS) was 97.6 months (85.6-109.7) in the VP2 group, which was not significantly different to that of the VP1 group [hazard ratio (HR), 1.008 (0.999-1.108); P=0.509]. The main toxicity was hematologic adverse events. The VP2 group had significantly higher rates of all grades of anemia, leukopenia, neutropenia, and thrombocytopenia (all P<0.05), as well as grade 3 or 4 of leukopenia and neutropenia (P<0.05) compared to the VP1 group. Regarding postoperative complications, the VP2 group had a significantly higher rate of pulmonary infection than the VP1 group (P<0.05). Conclusions Compared with VP2, VP1 showed comparable efficacy in terms of survival, with less hematologic toxicity and postoperative pulmonary infection. Therefore, we recommended that VP1 over VP2 to be the optimized VP neoadjuvant chemotherapy regimen for locally advanced esophageal squamous cell cancer.

Abstract
STUDY DESIGN Retrospective analysis. OBJECTIVE To define C2-C3 vertebral disc angle (VDA) in patients with and without cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA C2-C3 VDA is a new radiological index of cervical spine alignment. Recent studies have suggested that high postoperative values are associated with greater mechanical complications in patients with cervical spondylotic myelopathy. However, normative values for patients without myelopathy has yet to be defined. METHODS Patients with and without cervical myelopathy between 2017 and 2019 were included. Inclusion criteria were patients above 18 years of age with antero-posterior (AP) and lateral (LAT) cervical X-rays. In the non-myelopathic group, patients were excluded if they had neurological symptoms or deficits, presence of cervical axial pain, previous spinal surgery, or diagnosis of either spondylolisthesis or scoliosis. In the myelopathic group, patients were excluded if they had previous spinal surgery. Radiological indices evaluated include: C2-C3 disc angle, C2-C7 Cobb angle, C7 sagittal vertical axis, T1 slope. RESULTS In total, 99 patients without myelopathy and 22 patients with myelopathy were identified and analyzed. In patients without myelopathy, the mean for C2-C3 VDA was 25.9±7.9. For patients with myelopathy, preoperative values were 24.4±10.0 and 27.1±7.9 postoperatively. No statistically significant differences were found between patients with and without myelopathy. C2-C3 disc angle was not correlated with age (R=-0.173). CONCLUSION This study did not find statistically significant differences in C2-C3 VDA values between patients with and without cervical myelopathy. This study provides normative data for C2-C3 vertebral disc angle in patients with and without cervical spondylotic myelopathy. Furthermore, C2-C3 vertebral disc angle may be independent from age.

Abstract
Objective: To investigate the effect of heat shock protein 60 (HSP60) overexpression on the ability of bone marrow mesenchymal stem cells (MSCs) and its therapeutic effect on rats with phosgene induced acute lung injury. Methods: HSP60 was transfected into MSCs by adenovirus. Western blot was used to measure the expressions of HSP60 before and after transfection. CCK-8 assay was used to detect the activity of MSCs, flow cytometry was used to detect the apoptotic ability of MSCs, and Transwell assay was used to observe the migration ability of MSCs. Sixty SPF grade male SD rats were randomly divided into control group, phosgene exposure group (inhalation of phosgene for 5 min) , MSCs group (phosgene exposure, MSCs treatment group) and transfected MSCs group (phosgene exposure, overexpression of HSP60 MSCs treatment group) . The pathological changes of lung were observed by lung pathological section, lung wet dry ratio, the degree of pulmonary edema, the total cell count and total protein content of alveolar lavage fluid, the inflammatory changes of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in BALF and serum were observed. The data were analyzed by Graphpad Prism 8.0 software. Paired comparisons were performed by non paired t-test. One way ANOVA was used for comparison between groups. Results: The proliferation ability of MSCs transfected with HSP60[A= (0.69±0.05) ] was significantly higher than that of MSCs not transfected with HSP60[A= (0.27±0.02) ] (P<0.05) . Compared with the phosgene exposure group, the pulmonary edema and inflammatory factor infiltration of MSCs group and MSCs transfected group were reduced. However, compared with MSCs group, the degree of pulmonary edema in MSCs transfected group was significantly improved, the levels of inflammatory factors IL-6 and TNF-α were significantly decreased, and the total protein content and total cell count in bronchoalveolar lavage fluid were less (P<0.05) . Conclusion: MSCs transfected with HSP60 can enhance the ability of proliferation, anti apoptosis, migration and the curative effect in rats with phosgene induced acute lung injury.

Abstract
Background Primary adenoid cystic carcinoma (ACC) of the lung, which arises from the bronchial gland and is rare, accounting for only 0.04–0.2% of all primary lung tumors. The genetic profiling of bilateral ACC of unknown primary site and application in postoperative decision-making are less reported. Case Presentation A 57-year-old male with a smoking history of over 30 years and multiple nodules in both lungs was present to our department. After assessing the bilateral solid nodules in his Positron Emission Tomography–Computed Tomography (PET/CT) scan, malignant lesions at the left lower lung, right lower lung, and right middle lung are suspected. Sequential selective video-assisted thoracoscopic surgeries (VATS) were performed. A genetic alteration test of 425 cancer-related genes and global gene expression profile of the specimens revealed intrapulmonary metastasis existed. The patient was followed up for three years without recurrence and tissue mutations in liquid biopsy. Conclusion We present a way of omics-based multiple pulmonary lesions origin assessment, facilitating post-operative differential diagnosis and treatment decision for difficult cases.

Abstract
AIM To evaluate the lung function of coronavirus disease 2019 (COVID-19) patients using oxygen-enhanced (OE) ultrashort echo time (UTE) MRI. MATERIALS AND METHODS Forty-nine patients with COVID-19 were included in the study. The OE-MRI was based on a respiratory-gated three-dimensional (3D) radial UTE sequence. For each patient, the percent signal enhancement (PSE) map was calculated using the expression PSE = (S100% – S21%)/S21%, where S21% and S100% are signals acquired during room air and 100% oxygen inhalation, respectively. Agreement of lesion detectability between UTE-MRI and computed tomography (CT) was performed using the kappa test. The Mann–Whitney U-test was used to evaluate the difference in the mean PSE between mild-type COVID-19 and common-type COVID-19. Spearman's test was used to assess the relationship between lesion mean PSE and lesion size. Furthermore, the Mann–Whitney U-test was used to evaluate the difference in region of interest (ROI) mean PSE between normal pulmonary parenchyma and lesions. The Kruskal–Wallis test was applied to test the difference in the mean PSE between different lesion types. RESULTS CT and UTE-MRI reached good agreement in lesion detectability. Ventilation measures in mild-type patients (5.3 ± 5.5%) were significantly different from those in common-type patients (3 ± 3.9%). Besides, there was no significant correlation between lesion mean PSE and lesion size. The mean PSE of COVID-19 lesions (3.2 ± 4.9%) was significantly lower than that of the pulmonary parenchyma (5.4 ± 3.9%). No significant difference was found among different lesion types. CONCLUSION OE-UTE-MRI could serve as a promising method for the assessment of lung function or treatment management of COVID-19 patients.

Abstract
Immunologic checkpoint blockade has been proven effective in a variety of malignancies. However, high rates of resistance have substantially hindered its clinical use. Understanding the underlying mechanisms may lead to new strategies for improving therapeutic efficacy. Although a number of signaling pathways have been shown to be associated with tumor cell-mediated resistance to immunotherapy, T cell-intrinsic resistant mechanisms remain elusive. Here, we demonstrated that diacylglycerol kinase alpha (Dgka) mediated T-cell dysfunction during anti-PD-1 therapy by exacerbating the exhaustion of reinvigorated tumor-specific T cells. Pharmacologic ablation of Dgka postponed T-cell exhaustion and delayed development of resistance to PD-1 blockade. Dgka inhibition also enhanced the efficacy of anti-PD-1 therapy. We further found that the expression of DGKA in cancer cells promoted tumor growth via the AKT signaling pathway, suggesting that DGKA might be a target in tumor cells as well. Together, these findings unveiled a molecular pathway mediating resistance to PD-1 blockade and provide a potential therapeutic strategy with combination immunotherapy.

A large real-world cohort study of examined lymph node standards for adequate nodal staging in early non-small cell lung cancer. Transl Lung Cancer Res 2021; 10:815-825. [PMID: 33718024 PMCID: PMC7947406 DOI: 10.21037/tlcr-20-1024] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Accepted: 12/23/2020] [Indexed: 12/25/2022]
Abstract
BACKGROUND The current National Comprehensive Cancer Network (NCCN) guidelines for non-small cell lung cancer (NSCLC) recommend that surgeons sample is not clear. We aimed to define a minimal number of examined lymph nodes for removal or sampling for optimized nodal staging recommendation, with a focus on T1-3N0M0 patients. METHODS A total of 55,101 consecutive patients were selected, including 52,099 patients with US Surveillance, Epidemiology, and End Results (SEER) data and 3,002 patients in a Chinese multicenter database from 11 thoracic referral centers, who underwent complete resection plus lymph node dissection or sampling for stage T1-3N0M0 NSCLC. Propensity score-matching analysis was performed with R software, and a cut-off value was calculated using X-tile software. Survival was evaluated using the Kaplan-Meier method and Cox proportional hazard models. RESULTS Five-year survival rates with respect to total examined lymph nodes numbers (examined lymph nodes <10 vs. examined lymph nodes ≥10) were 69% and 64% (group A), 66% and 63% (group B), 62% and 58% (group C), 81% and 75% (group D). There were significant differences between examined lymph nodes <10 and examined lymph nodes >10 in each group (P<0.001). CONCLUSIONS A minimum of 10 examined lymph nodes would significantly improve T1-3N0M0 NSCLC prognosis and patients' survival rates if implemented as a minimum standard for lymphadenectomy. Therefore, we recommended a minimum of 10 examined lymph nodes for T1-3N0M0 patients.

Abstract
OBJECTIVES This study systematically reviewed evidence from interventions on the effect of front-of-package (FOP) nutrition labeling on food purchases. STUDY DESIGN The study design used in this study is a systematic review. METHODS Keyword search was performed in PubMed, Web of Science, Scopus, and Cochrane Library. RESULTS Fifteen studies (10 randomized controlled trials, four pre-post studies, and one case-control study) met the eligibility criteria and were included in the review. Five studies were conducted in a controlled setting through the establishment of an online virtual supermarket or physical laboratory food store solely for the intervention. In contrast, the remaining ten studies were conducted in a naturalistic setting where people commonly purchase foods (e.g., supermarket, grocery store, school/hospital cafeteria, or vending machine). FOP labels assessed included traffic lights, health star rating, daily intake guides, health warnings, and high sugar symbol labels. Compared with the control, FOP labels were effective for helping participants make healthier food purchase decisions in five of the 12 studies that assessed traffic lights labels, in one of the two studies that assessed health warning labels, and in one study that assessed high sugar symbol labels. Three assessed health star ratings and one assessed daily intake guide labels, but none revealed an effect on food purchases compared with the control. CONCLUSIONS Findings on the effectiveness of FOP nutrition labels in 'nudging' consumers toward healthier food purchases remain mixed and inconclusive. Future studies should examine other types of FOP labels beside the traffic lights labels and explore the different effects by consumer affordability, population subgroup, and shopping environment.

Abstract
Objective: To investigate the relationship between human papillomavirus (HPV) integration and prognosis of cervical cancer patients. Methods: The data of 82 patients with cervical cancer treated in the Radiotherapy Department of Peking Union Medical College Hospital from October 2004 to June 2012 were retrospectively analyzed.The patients were divided into poor prognosis group (recurrence or metastasis after surgery and adjuvant radiotherapy) and good prognosis group based on a propensity score matching strategy.The HPV integration of the two groups were detected by whole exome sequencing to determine whether the integration sites were located in the common fragile sites (CFSs). HPV integration and integration into CFSs were compared between the two groups. Results: Among the enrolled 82 patients, 37 were divided in poor survival group and 45 in good survival group. A total of 90 integration breakpoints were identified, 30 of them occurred in poor prognosis group and 60 occurred in good prognosis group. In the poor prognosis group, HPV integration occurred in 20 patients, 13 of them were inserted in CFSs of 11 patients, and the numbers in good prognosis group were 26, 17, 11, respectively. There were no significantly statistical differences in the number of HPV integration events (P=0.289), HPV integration patients (P=0.735), CFSs integration events (P=0.427), and CFSs integration patients (P=0.591) between the two groups. In poor prognosis group, more CFSs integration events occurred in patients with metastasis than those in patients with only local recurrence (9 vs 2, P=0.003). Conclusions: No significant differences are observed in HPV integration and HPV integration into CFSs between cervical cancer patients with different prognoses. HPV integration into CFSs may be associated with distant metastasis.
