Abstract
Background The benefits of postoperative chemotherapy in patients with estrogen receptor (ER)-positive breast cancer remain unclear. The use of tumor grade, Ki-67, or ER expression failed to provide an accurate prognosis of the risk of relapse after surgery in patients. This study aimed to evaluate whether a multigene assay Curebest™ 95GC Breast (95GC) can identify the risk of recurrence and provide more insights into the requirements for chemotherapy in patients. Methods This single-arm retrospective multicenter joint study included patients with ER-positive, node-negative breast cancer who were treated at five facilities in Japan and had received endocrine therapy alone as adjuvant therapy. The primary lesion specimens obtained during surgery were analyzed using the 95GC breast cancer multigene assay. Based on the 95GC results, patients were classified into low-risk (95GC-L) and high-risk (95GC-H) groups. Results The 10-year relapse-free survival rates were 88.4 and 59.6% for the 95GC-L and 95GC-H groups, respectively. Histologic grade, Ki-67, and PAM50 exhibited a significant relationship with the 95GC results. The segregation into 95GC-L and 95GC-H groups within established clinical factors can identify subgroups of patients using histologic grade or PAM50 classification with good prognosis without receiving chemotherapy. Conclusions Based on the results of our retrospective study, 95GC could be used to evaluate the long-term prognosis of ER-positive, node-negative breast cancer. Even though further prospective validation is necessary, the inclusion of 95GC in clinical practice could help to select optimal treatments for breast cancer patients and identify those who do not benefit from the addition of chemotherapy, thus avoiding unnecessary treatment.

Abstract
Abstract
Study question
The aim of this study is to analyse the association between blastocyst diameter and TVs development, and to examine the efficacy of AH.
Summary answer
Blastocysts with a diameter of more than 170 μm leads to high incidence of TVs and AH applied from the incidence should be effective.
What is known already
TVs are protrusion of trophectoderm cells often observed in expanding blastocyst stages. TVs can be observed in expanding blastocysts regardless of Intracytoplasmic sperm injection (ICSI) and Conventional-IVF (C-IVF), when the internal pressure of blastocysts increase. The rate of TVs incidence in blastocysts inseminated by ICSI is higher than that by C-IVF, due to penetration of the needle into the zona pellucida. Moreover, it has been reported that TVs may inhibit blastocyst hatching. However, the developmental timing of TVs is still unclear, and there is no study that has analysed the association between blastocyst diameter and the incidence of TVs.
Study design, size, duration
1) Diameters and TVs incidence of blastocysts by ICSI and C-IVF were measured, and the cut-off value and the area under the curve (AUC) of the receiver operating characteristic (ROC) curve were calculated to estimate the timing of TV incidence. 2) We analysed the clinical pregnancy rates of blastocysts with TVs treated by AH compared to those of blastocysts by C-IVF not subjected to AH.
Participants/materials, setting, methods
This study included 821 transferred frozen blastocysts ranging from March 2018 to November 2019. The embryos were cultured in a dry incubator after insemination by ICSI or C-IVF. Blastocyst freezing conditions were set at day5 to day7 with a diameter of more than 150 μm in inner diameter of zona pellucida, and this was measured before freezing. The ROC curve was performed using EZR statistical analysis software.
Main results and the role of chance
1) The incidence of TVs in blastocysts by ICSI and C-IVF was 27.5% (117/424) and 14.6% (58/397) respectively. The rate of the incidence of TVs in blastocysts inseminated by ICSI and C-IVF; 8.6% (12/140) and 0.95% (1/105) in 150–159 μm, 12.7% (14/110) and 8.2% (6/73) in 160–169 μm, 40.6% (28/69) and 10.5% (6/57) in 170–179 μm, 55.6% (30/54) and 25.5% (13/51) in 180–189 μm, 66.7% (20/30) and 35.7% (10/28) in 190–199 μm, and 68.4% (13/19) and 26.8% (22/82) in the diameter of more than 200 μm. The cut-off value of the ROC curve was respectively 170 μm (sensitivity 78.6% and specificity 73.0%) and 176 μm (sensitivity 84.5% and specificity 59.6%) in the diameter; the AUC was 0.8 [95%CI:0.752–0.848] and 0.74 [95%CI:0.687–0.793] respectively. 2) The clinical pregnancy rate of TVs blastocyst vs C-IVF blastocyst was 52.7% (88/167) vs 57.8% (37/64) respectively. There is no significant difference between the two clinical pregnancy rates (P = 0.556).
Limitations, reasons for caution
The findings of this study have to be seen in light of some limitations. Since this study aimed to analyse the incidence of TVs based on blastocyst size, we did not take into account the grade according to the Gardner classification and the number of trophectoderm cells.
Wider implications of the findings: Blastocysts inseminated by ICSI and C-IVF were highly likely to have TVs above 170 μm and 176 μm respectively. The clinical pregnancy rates of the blastocyst with TV treated by AH was similar to those of the C-IVF blastocyst.

Abstract
Neutrophil adhesion on the atheroprone femoral artery of high-fat diet-fed low-density lipoprotein receptor-null mice was enhanced more than in wild-type mice. The inhibition of histone H3 citrullination of neutrophils reversed the enhancement of neutrophil adhesion, suggesting that hypercitrullination contributes to enhanced neutrophil adhesion. Furthermore, pemafibrate reduced the citrullination of histone H3 in these mice. Therefore, the hypercitrullination of histone H3 in neutrophils contributes to atherosclerotic vascular inflammation.

Abstract
The analysis method of the Motional Stark Effect (MSE) diagnostic to measure the rotational transform and current profiles in the Large Helical Device has been improved. This was done by using the Variational Moments Equilibrium Code to calculate an equilibrium database for various pressure profiles and current profiles. This method looks for the radial profile of the rotational transform in the equilibrium database that gives the best fit to the polarization angle profiles measured with the MSE diagnostic. This analysis improves the measurements of rotational transform, especially near the magnetic axis, where the sensitivity of the polarization angle measurements becomes low and the uncertainty due to error in the estimation of the Pfirsch-Schlüter current becomes large. The radial profiles of the rotational transform and current profiles for Electron Cyclotron Current Drive and Neutral Beam Current Drive are obtained in the new analysis method with a sufficiently high accuracy to discuss the discrepancy of the current density profiles between the measurements and the calculations.

Abstract
Few university-based regenerative medicine innovations in the dental, oral, and craniofacial (DOC) space have been commercialized and affected clinical practice in the United States. An analysis of the commercial translation literature and National Institute for Dental and Craniofacial Research's (NIDCR's) portfolio identified barriers to commercial translation of university-based DOC innovations. To overcome these barriers, the NIDCR established the Dental Oral Craniofacial Tissue Regeneration Consortium. We provide generalized strategies to inform readers how to bridge the "valley of death" and more effectively translate DOC technologies from the research laboratory or early stage company environment to clinical trials and bring needed innovations to the clinic. Three valleys of death are covered: 1) from basic science to translational development, 2) from translational technology validation to new company formation (or licensing to an existing company), and 3) from new company formation to scaling toward commercialization. An adapted phase-gate model is presented to inform DOC regenerative medicine teams how to involve regulatory, manufacturability, intellectual property, competitive assessments, business models, and commercially oriented funding mechanisms earlier in the translational development process. An Industrial Partners Program describes how to conduct market assessments, industry maps, business development processes, and industry relationship management methods to sustain commercial translation through the later-stage valley of death. Paramount to successfully implementing these methods is the coordination and collaboration of interdisciplinary teams around specific commercial translation goals and objectives. We also provide several case studies for translational projects with an emphasis on how they addressed DOC biomaterials for tissue regeneration within a rigorous commercial translation development environment. These generalized strategies and methods support innovations within a university-based and early stage company-based translational development process, traversing the many funding gaps in dental, oral, and craniofacial regenerative medicine innovations. Although the focus is on shepherding technologies through the US Food and Drug Administration, the approaches are applicable worldwide.

Abstract
Veno-venous extracorporeal membrane oxygenation (VV ECMO) is an effective and proven adjunct support for various severe respiratory failures requiring invasive mechanical ventilation and cardiovascular support. In response to the rapidly increasing number of COVID-19 patients in Japan, we launched an ECMO support team comprised of multidisciplinary experts including physicians, nurses, perfusionists, and bioethicists in preparation for the threat of a pandemic. From April 2 to July 15, 2020, Tokyo Medical and Dental University hospital treated 104 PCR confirmed COVID-19 patients. Among those, 34 patients were admitted to intensive care unit (ICU) and 5 patients required VV ECMO. All management related to ECMO was decided by the ECMO support team in addition to participation of the ECMO support team in daily multidisciplinary rounds in the ICU. Median age was 54 years old. Duration from onset to mechanical ventilation (MV) and MV to ECMO were 8 and 7 days, respectively. Four patients (80%) were successfully weaned off from ECMO. One patient died after 81 days of ECMO run. Four patients were discharged and recovered to their prehospital quality of life without major disability. We achieved a high survival rate using ECMO in our low volume ECMO institution during the COVID-19 pandemic. Multidisciplinary decision-making and a team approach for the unclear pathology with an emerging infectious disease was effective and contributed to the survival rate.

Abstract
Leukocytes play an important role in vascular inflammation prior to atherosclerosis. In particular, monocyte adhesion and migration to the endothelium contribute to the development of vascular inflammation. Previously, we showed the importance of neutrophils and complement C5a in the early phase of vascular inflammation in mice fed a high-fat diet. However, the relationship between monocytes and neutrophils is not well understood. In this study, we elucidated the involvement of neutrophils in the migration of monocytes. We observed that C5a induces CCL2 expression in neutrophil-like dHL-60 cells. To investigate the physiological significance of CCL2 secretion, we performed a chemotaxis assay. Interestingly, dHL-60 culture supernatant in the presence of C5a enhanced the migration of THP-1 in comparison with the absence of C5a. Furthermore, CCL2 expression and secretion significantly increased in C5a-stimulated dHL-60 through the phosphorylation of NF-κB p65. Actin polymerization on THP-1 was enhanced by the presence of C5a compared with the absence of C5a when stimulated by a dHL-60-cultured medium. These results suggest that crosstalk between neutrophils and monocytes via CCL2 may play an important role in vascular inflammation.

Abstract
We report a case of total mastectomy and contralateral axillary lymph node dissection (ALND) in a patient with ipsilateral breast tumor recurrence (IBTR) and contralateral axillary lymph node metastasis (ALNM), with lymphoscintigraphy, confirming that the primary lymphatic flow was directed to the contralateral ALNM. The patient in the present case study is a 63-year-old woman. At the age of 46 years, the patient underwent lumpectomy and sentinel lymph node biopsy (SLNB) for left breast cancer. After surgery, she underwent whole-breast irradiation and hormone therapy (tamoxifen) for 5 years. On follow-up, she did not have recurrence. When she underwent breast ultrasound examination at the 17-year checkup after the initial surgery, she was diagnosed with tumor recurrence in the left conserved breast and with contralateral ALNM, without distant metastasis to any other organ. When re-SLNB is performed in patients with IBTR, the primary lymphatic flow is directed toward a lymph node other than the ipsilateral axillary lymph node (ALN). Therefore, it is necessary to discuss whether or not the contralateral ALNM in our case should be treated as stage IV. Therefore, we performed ALND after confirming that the primary lymphatic flow was directed toward the contralateral ALN as observed on lymphoscintigraphy and considering the contralateral ALNM as a localized lesion. Lymphoscintigraphy and intraoperative fluorescence imaging aid in the identification of the primary lymphatic flow. Lymph node metastases beyond the altered primary lymphatic flow are treated as localized lesions, and aggressive surgery is expected to be effective. There is a need to formulate guidelines on the treatment of IBTR considering changes in primary lymphatic flow.

Abstract
OBJECTIVE The Japan Clinical Oncology Group 1505 trial is a single-arm multicentre prospective study that examined the possibility of non-surgical follow-up with endocrine therapy for patients with low-grade ductal carcinoma in situ. In that study, the eligible criteria included histopathological findings comprising low to intermediate nuclear grade and absence of comedo necrosis, and cases were entered according to the local histopathological diagnosis. Nuclear grade is largely based on the Consensus Conference criteria (1997), whereas comedo necrosis is judged according to the Rosen's criteria (2017). The purpose of this study was to standardize and examine the interobserver agreement levels of these histopathological criteria amongst the participating pathologists. METHODS We held slide conferences, where photomicrographs of haematoxylin-eosin-stained slides from 68 patients with ductal carcinoma in situ were presented using PowerPoint. The nuclear grade and comedo necrosis statuses individually judged by the pathologists were analysed using κ statistics. RESULTS In the first and second sessions, where 22 cases each were presented, the interobserver agreement levels of nuclear grade whether low/intermediate grade or high grade were moderate amongst 29 and 24 participating pathologists, respectively (κ = 0.595 and 0.519, respectively). In the third session where 24 cases were presented, interobserver agreement levels of comedo necrosis or non-comedo necrosis were substantial amongst 25 participating pathologists (κ = 0.753). CONCLUSION Although the concordance rates in nuclear grade or comedo necrosis were not high in a few of the cases, we believe that these results could provide a rationale for employing the present criteria of nuclear grade and comedo necrosis in the clinical study of ductal carcinoma in situ.

Abstract
Fear, anxiety, and preference in fish are generally evaluated by video-based behavioural analyses. We previously proposed a system that can measure bioelectrical signals, called ventilatory signals, using a 126-electrode array placed at the bottom of an aquarium and achieved cameraless real-time analysis of motion and ventilation. In this paper, we propose a method to evaluate the emotional state of fish by combining the motion and ventilatory indices obtained with the proposed system. In the experiments, fear/anxiety and appetitive behaviour were induced using alarm pheromone and ethanol, respectively. We also found that the emotional state of the zebrafish can be expressed on the principal component (PC) space extracted from the defined indices. The three emotional states were discriminated using a model-based machine learning method by feeding the PCs. Based on discrimination performed every 5 s, the F-score between the three emotional states were as follows: 0.84 for the normal state, 0.76 for the fear/anxiety state, and 0.59 for the appetitive behaviour. These results indicate the effectiveness of combining physiological and motional indices to discriminate the emotional states of zebrafish.

Abstract
The purposes of this study are to integrate organizational social capital theory and consumer happiness in a prior brand identification model and test the antecedents and consequences of consumer-brand identification over time. In the context of professional football, we collected data from 374 panel registrants of an online research service firm throughout a season. The results indicated consumer-brand identification was impacted to a greater extent by two social capital factors: (1) social interaction ties and (2) shared vision, than by brand prestige and brand distinctiveness. Both social interaction ties and consumer-brand identification were also predictive of future behavioral loyalty and purchase frequency. Further, our moderation analysis revealed the impact of consumer-brand identification on behavioral loyalty was contingent on consumer happiness. The proposed framework and results reinforce the importance of consumer-to-consumer social capital and consumer happiness and add new insights into the dynamics of consumer-brand identification, consumer happiness, and enduring consumer loyalty.

Abstract
The patient is 77-year-old man. He received open cholecystectomy and choledocholithotomy when he was 74 years old. Because postoperative diagnosis was small cell neuroendocrine carcinoma(NEC), the resection of gallbladder bed and hilus lymph nodes were performed. During the follow up period, the liver metastases and portal vein tumor thrombosis appeared. Therefore, chemotherapy was performed according to small cell lung cancer. In addition to chemotherapy, radiation therapy was performed for the purpose of local control. He is still alive about 3 years after the first operation. This case suggested the efficacy of multidisciplinary treatment including operation, chemotherapy, and radiation therapy in NEC of gallbladder patient with liver metastasis.

Abstract
The patient was a 73-year-old man, diagnosed as advanced gastric cancer with para-aortic lymph nodes(PAN)metastasis. He was treated by 3 courses of neoadjuvant chemotherapy(NAC)with S-1 and oxaliplatin(SOX therapy). CT showed significant reduction of both primary tumor and metastatic lymph nodes. We performed distal gastrectomy with D2 plus PAN dissection. The histopathological findings showed no residual viable tumor cell. The pathological effect of chemotherapy was judged Grade 3(pCR)in both primary tumor and dissected lymph nodes. He is alive without recurrence 21 months after surgery.

Abstract
A 59-year-old man visited our department because of cholecystectomy. Preoperative CT revealed a tumor shadow measuring 50 mm in front of the right iliopsoas muscle. MRI showed a low signal intensity on T1-weighted images and a slightly high signal intensity on the T2-weighted image. PET-CT showed accumulation of FDG(SUVmax 5.39)in the tumor but no other abnormal accumulations. We performed tumor resection for diagnostic purposes because malignancy could not be ruled out owing to the large size of the mass. Intraoperative findings showed a well-circumscribed margin of the tumor without invasion to other tissues. The retroperitoneum was incised circumferentially along the tumor under laparoscopic guidance, and the tumor was resected. Histopathological and immunostaining findings were consistent with leiomyosarcoma. In laparoscopic surgery, the surgical margin is observed in detail through the magnifying effect. Therefore, laparoscopic surgery can be a surgical option for tumors that may be completely excised based on preoperative findings.

Abstract
Adipose-derived stem cells (ASCs) exhibit self-renewal and pluripotency. The differentiation potency of ASCs has been reported to deteriorate with aging; however, relevant studies used ASCs that were isolated and subcultured several times. It is still unclear whether subcultured ASCs accurately reflect the in vivo state. To address this question, we used freshly isolated stromal vascular fractions (SVFs) and performed comprehensive single-cell transcriptome analysis. In this study, we identified three cell populations as putative ASC candidates in SVFs and three novel ASC-related genes: Adamts7, Snai2, and Tgfbr1, that are reported to be negative regulators of cell differentiation. Moreover, we identified age-associated high gene expression levels of Adamts7, Egfr, and Igfbp4 in the earliest differentiation stage of ASCs. These results suggest that aging may make it impossible to maintain the stringency of the regulation of the expression of some genes related to ASC differentiation.

Abstract
BACKGROUND It has been determined that axillary lymph node dissection after the detection of limited axillary lymph node metastasis does not improve the prognosis of patients with breast cancer. Thus, a need exists for less-invasive axillary surgery. However, it remains unclear whether a predictive model based on preoperative data would be sufficient to accurately predict the probability of pN2-N3 (> 3 lymph node metastases). We sought to develop an easy-to-use scoring system to distinguish between pN0-N1 (0-3 lymph node metastases) and pN2-N3 using only preoperative data and validate its predictive performance. PATIENTS AND METHODS We retrospectively identified 2687 patients diagnosed with cT1-3cN0-N1 who had undergone surgery in our hospital from 2013 to 2019. We evaluated the risk factors associated with pN2-N3 by logistic regression analysis and developed a scoring system. Predictive performance was assessed by calculating the receiver operating characteristic area under the curve (AUC) and was validated using K-fold cross-validation. RESULTS We identified 1987 patients with stage pN0, 522 with pN1, and 178 with pN2-N3. Multivariate analysis revealed tumor size, number of suspicious lymph nodes on axillary ultrasound examination, histologic type, histologic grade, and receptor status were significant risk factors for pN2-N3. The AUC value was 0.87, and the mean AUC of the 10-fold cross-validation was 0.88. When the cutoff score was set at 6, the negative predictive value for excluding patients with pN2-N3 was 98.4%. CONCLUSION Our easy-to-use scoring system could be useful to preoperatively identify patients at lower risk of pN2-N3 and avoid unnecessary axillary lymph node dissection.

Abstract
Abstract
Background
For the prevention of future cardiovascular events, control of residual risks such as triglyceride rich lipoproteins and HDL-cholesterol is an emerging problem beyond LDL-cholesterol. Triglyceride to HDL-cholesterol ratio (TG/HDL ratio) has been reported to be useful for risk classification of cardiovascular diseases. Meanwhile, several studies showed that high-risk plaque characteristics evaluated with coronary CT angiography (cCTA) was associated with the incidence of acute coronary syndrome. However, the relationship of TG/HDL ratio with coronary plaque characteristics and its impact of this association on future coronary events have not been fully elucidated.
Purpose
The aim of this study was to evaluate the association between TG/HDL ratio and high-risk plaque detected by cCTA and its impact on future coronary events.
Methods
A total of 944 patients suspected stable coronary artery disease who underwent cCTA at our institution were analyzed (mean 64-year-old, 55% male). Patients were divided into two groups by the median value of TG/HDL ratio (higher TG/HDL: TG/HDL ratio ≥2.0, lower TG/HDL: TG/HDL ratio <2.0). Coronary high-risk plaques were defined as a plaque with all three components; low attenuation plaque (<50H.U.), positive remodeling (remodeling index >1.1) and spotty calcification. Cardiovascular event was defined as cardiovascular death, acute coronary syndrome, and late coronary revascularization after 30 days of CT acquisition.
Results
The higher TG/HDL ratio was significantly associated with male gender (63% vs. 48%, P<0.001), body mass index (24.8±3.8 vs. 22.9±4.0, p<0.001), the prevalence of hypertension (65% vs. 54%, P<0.001), dyslipidemia (60% vs. 42%, P<0.001), diabetes mellitus (38% vs. 27%, P=0.001) and current smoking (26% vs. 10%, p<0.001). Regarding cCTA findings, the prevalence of significant stenosis, calcified plaque, non-calcified plaque, coronary plaques with low attenuation plaque, positive remodeling and spotty calcification in the higher TG/HDL group were greater than those in the lower group (Figure 1A). Of note, the difference in high-risk plaque between two groups was significant. (18% vs. 11%, p=0.004). Multivariate logistic analysis revealed that the TG/HDL ratio was an independent risk factor for high-risk plaque even after adjustment (OR, 1.35; 95% CI, 1.01–1.81; p=0.049). Regarding coronary events (median follow-up duration; 48 months), Kaplan-Meier curve showed poor event-free rate in the higher TG/HDL group (Figure 1B). At Cox proportional hazard analysis, higher TG/HDL ratio (HR, 1.94; 95% CI, 1.01–3.70; p=0.046) and CT-verified high-risk plaque (HR, 2.36; 95% CI, 1.27–4.38; p=0.006) were independent predictive factors for coronary events even after adjustment.
Conclusion
TG/HDL ratio is involved in the vulnerability of CT-verified coronary plaque characteristics. This association may play an important role in the prognostic impact of TG/HDL ratio on future cardiovascular events.

Abstract
Abstract
Background
Recently, post pulmonary embolism (PE) syndrome or chronic thromboembolic disease after acute PE, has been recognized as important long-term complications. Furthermore, patients may develop with chronic thromboembolic pulmonary hypertension.
Purpose
We aimed to evaluate the frequency of residual pulmonary thromboemboli after acute PE by using our “higher”-resolution CT scan imaging method to detect residual thromboemboli down to sub-segmental pulmonary arteries.
Methods
This study was a prospective multi-center observational study. We enrolled consecutive 34 patients with acute symptomatic PE whose informed consent was obtained, and followed up for one year. One year after the onset of acute PE, patients were referred to our hospital and multiple examination including CT scan, 6-minute walk test (6MWT), questionnaire of SF-36, echocardiography and laboratory testing were performed. Additionally, we have modified the CT obstruction index (CTOI) to quantitatively evaluate the thromboemboli down to sub-segmental pulmonary arteries.
Results
Mean age was 60.5±15.8 years, and 56% were male. No patient was categorized as low recurrent VTE risk which was caused by transient factors, one patient was associated with active cancer, and 12% had known thrombophilia. In 85% of the patients, this onset was the first obvious episode of PE. At diagnosis, elevated B-type natriuretic peptide (BNP) (≥100 pg/ml) or N-terminal (NT)-proBNP (≥500 pg/ml) was observed in 45% of the patients. Median tricuspid regurgitation peak gradient (TRPG) by echocardiography was 30.9 (19.3–50.1) mmHg. Among all, 35% of the patients received single-drug approach with DOACs. At discharge, all of the patients except two were treated with DOACs.
One year after the onset, 21% of the patient were in NYHA II and others were in NYHA I. It was notable that pulmonary thromboemboli was detected by our CT scan in 76% of the patients. Modified CTOI was median 11.9 (1.8–24.4) % as shown in the figure.
In multiple regression analysis, TRPG at diagnosis and BNP at one month were significantly associated with mCTOI (β=0.536, p=0.002 and β=−0.482, p=0.003, respectively). Additionally, lowest SpO2 during 6MWT after one year from the onset, tended to inversely associate with mCTOI (β=−0.341, p=0.052).
Conclusions
Using our modified CT scan imaging method and modified CTOI, residual pulmonary thromboemboli was able to be detected more frequently than the previous studies. Residual pulmonary thromboemboli could be one of the cause of the post PE syndrome and lead to exercise-induced desaturation.

Abstract
Abstract
Background
Venous thromboembolism (VTE) is the third frequent acute cardiovascular syndrome in the Europe and Japan. Since direct oral anticoagulants (DOACs) are widely used now, the morbidity and mortality of pulmonary embolism (PE) patients especially associated with cancer needs to be re-evaluated.
Purpose
We evaluated the clinical course of patients with PE mainly treated with DOACs.
Methods
This retrospective observational study was conducted in a single center. The data were collected from the medical record of consecutive patients who received inpatient treatment of PE. In this study, we have compared PE patients with cancer (cancer PE) to those without cancer (non-cancer PE) and evaluated the mortality, recurrent of VTE and major bleedings.
Results
In total, 140 patients were enrolled: 94 patients were cancer-related, and 46 patients were without cancer (Table). The type of the tumor in cancer PE patients were as follows: gastric 8 (9%), esophageal 5 (5%), pancreatic 12 (13%), lung 14 (15%), lymphoma 2 (2%), gynecologic 17 (18%), renal 2 (2%), bile duct 8 (9%), colon 12 (13%), and others 17 (18%).
Kaplan-Meier curve showed that the cumulative all-cause mortality was significantly higher in the cancer PE group (35/94 (37%) vs. 2/46 (4%), P<0.001 (log rank), HR 10.3 [95% CI:2.5–43.3]). The cumulative incidence of recurrent VTE was significantly higher in the cancer PE group (7/94 (7%) vs. 0/46, P=0.03 (log rank)). There was no significant difference in the cumulative incidence of major bleeding between the cancer PE group and the non-cancer PE group (8/94 (9%) vs. 5/46 (11%)).
Conclusions
The risk of recurrent VTE was still higher in cancer PE patients compared to non-cancer PE patients, although DOACs were used. Meanwhile the incidence of major bleeding was comparable in both groups, the risk of bleeding might be acceptable with using DOACs especially in cancer PE patients.
