RESUMEN

Bone metastases are often associated with pain and can occur in various types of cancer, significantly affecting patients' quality of life. Despite the high response rates to initial conventional radiotherapy in patients with painful spinal metastases, recurrence and inadequate response still occur. Thus, the development of a highly effective strategy for pain recurrence is crucial to improving the quality of life in patients with advanced metastatic cancer. This randomized phase III trial aims to confirm the superiority of re-irradiation with stereotactic body radiotherapy (24 Gy in 2 fractions) over conventional radiotherapy (8 Gy in a single fraction) in achieving a complete pain response at 12 weeks in patients with previously irradiated painful spinal metastases. A total of 158 patients from 33 hospitals will be enrolled in Japan over 3.5 years. This trial has been registered in the Japan Registry of Clinical Trials as jRCTs1030240172 (https://jrct.niph.go.jp/latest-detail/jRCT1030240172).

RESUMEN

BACKGROUND: Although several studies have investigated whether thoracic duct (TD) resection improves prognosis, the conclusion remains controversial. JCOG1109 is a three-arm randomized phase III trial to confirm the survival advantage of docetaxel, cisplatin, 5-fluorouracil (DCF), and cisplatin plus 5-fluorouracil (CF) combined with radiotherapy (CF-RT) over CF as neoadjuvant treatment. The study aimed to evaluate the survival impact of TD resection and its association with neoadjuvant treatment and pathological response in patients enrolled in JCOG1109. PATIENTS AND METHODS: Clinicopathological factors, surgical results, and prognosis were compared between TD preserved and resected groups. The survival impact of TD resection was also evaluated in the subgroups on the basis of combinations of preoperative therapy and pathological response. RESULTS: Between December 2012 and July 2018, 601 patients were randomized (CF/DCF/CF-RT; 199/202/200) in JCOG1109. Of them, 541 patients underwent esophagectomy (183/181/177), and TD was resected in 265 patients (93/91/81). For the entire cohort, TD resection was not a significant prognostic factor for overall survival in the multivariable analysis (HR 1.20, 95% CI 0.91-1.57). In the subgroup analyses by combinations of neoadjuvant treatment and pathological response, TD resected group had a significantly better overall survival compared with TD preserved group in patients who received DCF and achieved pathological response (HR 0.20, 95% CI 0.07-0.61). CONCLUSIONS: The survival benefit of TD resection was not demonstrated in patients with surgically resectable esophageal squamous cell carcinoma enrolled in JCOG1109. The residual tumor burden after neoadjuvant treatment might be linked to the survival impact of TD resection.

RESUMEN

Aim: Treatment options for esophageal squamous cell carcinoma includes surgery and chemoradiotherapy (CRT), however there was limited information about the factors influenced in patients' decision-making.Materials & methods: Patients who participated in JCOG0502, a parallel group controlled trial comparing surgery with CRT, were analyzed for the factors related to decision-making.Results: Of the 368 patients (pts) enrolled in the nonrandomized part in JCOG0502, 209 pts opted for surgery and 159 pts chose CRT on their own. Background characteristics were the same except for age. Multivariable logistic regression analysis showed that age ≥65 years, male sex, multiple lesions, absence of children and doctor's thinking were associated with the selection of CRT.Conclusion: The doctor's option was the most influential factor in the patient's decision-making process.Clinical Trial Registration: UMIN000000551 (ClinicalTrials.gov).

RESUMEN

BACKGROUND: This study aimed to clarify serum salicylic acid (SA) levels in patients with Kawasaki disease (KD) after the administration of moderate-dose acetylsalicylic acid (ASA) and their relationship with the therapeutic effect. METHODS: We retrospectively analyzed the clinical data of 142 children with KD. We measured serum SA trough levels during the acute and recovery periods and determined their relationship with clinical and laboratory parameters. RESULTS: The median age of patients was 2.4 years. Thirty-one patients had incomplete KD, 29 were intravenous immunoglobulin (IVIG) non-responders, and one patient had coronary artery lesions. The median ASA dose was 49.7 mg/kg/day. The median serum SA level was 22 µg/mL in the acute period and 15 µg/mL in the recovery period, with 45 (33%) in the acute period and 60 (44%) in the recovery period below the limit of measurement (< 10 µg/mL). Serum SA levels during the recovery period were significantly lower in patients who received steroids. There were no significant differences in IVIG responsiveness based on serum SA levels. CONCLUSIONS: Serum SA trough levels in KD patients treated with moderate-dose ASA were highly variable and did not reach sufficient levels. Serum SA levels were not associated with IVIG responsiveness.

RESUMEN

OBJECTIVE: Reports demonstrating the effectiveness and safety of strut-adjusted volume implants (SAVI) in Japan are limited. Therefore, this study aimed to compare the treatment outcomes of SAVI and whole-breast irradiation (WBI) at a single facility. MATERIALS AND METHODS: Data were retrospectively extracted from the medical records of patients treated with SAVI or WBI following partial mastectomy (Bp). Patients undergoing Bp, sentinel lymph node biopsy, and SAVI spacer insertion followed by brachytherapy with the SAVI device were compared to those followed with WBI. Local recurrence was assessed annually by physical examination, bilateral mammography, and breast ultrasonography. RESULTS: The SAVI and WBI groups comprised 53 and 113 patients, with a median age of 55 and 52 years, respectively; among them, 47 and 91 patients had a pathological tumor diameter ≤2 cm and six and 22 had a pathological tumor diameter >2 cm, respectively. Recurrence events, acute adverse events, and late adverse events were observed in the SAVI and WBI groups in 1 and 3 (p = 0.726), 24 and 79 (p = 0.01), and 24 and 18 patients (p = 0.00002), respectively, with median observation periods of 60.0 and 47.8 months, respectively. All adverse events were grades 1-2, with dermatitis being the most common in the acute phase. In the late phase, pigmentation was common in both groups. CONCLUSION: The local recurrence rate does not differ between SAVI and WBI within the relatively short-term follow-up period. Longer follow-up is required to confirm our results in the Japanese population.

RESUMEN

Prostaglandin E-major urinary metabolite (PGE-MUM) is a valuable biomarker reflecting the cytokine profile. We encountered a case of a 14-year-old boy with pan-colitis-type ulcerative colitis who was unresponsive to steroids and infliximab. The patient's clinical symptoms gradually deteriorated and surgical treatment was strongly considered because anti-inflammatory therapy was unlikely to be effective. PGE-MUM levels were markedly elevated, indicating a T-helper 17 (Th17)-like cytokine profile. Because an antibody against interleukin 23 (IL-23) was presumed to be effective, the patient was treated with mirikizumab, after which he achieved remission. In the present case, measurement of PGE-MUM levels was useful in selecting anti-cytokine treatments for severe ulcerative colitis.

RESUMEN

Fear of cancer recurrence (FCR) is a common and distressing condition among adolescents and young adults (AYAs). This study aims to investigate the efficacy of digital interventions, including distress screening-based information provision and smartphone problem-solving therapy, on common psychological distress, especially FCR, in AYA patients with cancer. Participants will be 224 AYA outpatients with cancer aged 15-39 years who will be randomly assigned to either an 8-week smartphone-based intervention or a waitlist control group. This intervention includes smartphone-based distress screening, information provision, and psychotherapy (problem-solving therapy). The primary endpoint will be the Fear of Cancer Recurrence Inventory-Short Form score at week 8. This study will be conducted as a fully decentralized, randomized, and multicenter trial. The study protocol was approved by the Institutional Review Board of Nagoya City University on 19 April 2024 (ID: 46-23-0005). Trial registration: UMIN-CTR: UMIN000054583.

RESUMEN

BACKGROUND: In patients with early-stage breast cancer following breast surgery, ultra-hypofractionated (UHF) breast/chest wall radiation therapy (RT) has been shown to be non-inferior to a moderate-hypofractionated (MHF) regimen, with a minimal risk of breast induration, in the FAST-Forward trial, and UHF is now becoming the standard regimen in Europe. Herein, we aimed to investigate Japanese patients' attitudes toward the UHF regimen. METHODS: A questionnaire-based survey was conducted at 13 RT centers in nine prefectures across Japan. All patients underwent breast-conserving surgery, followed by either conventional fractionation (2 Gy/fr) or MHF (2.66 Gy/fr) whole-breast irradiation (WBI) with or without a tumor bed boost. The questionnaire consisted of 13 questions mainly addressing quality-of-life during RT. Key questions included an 11-point scale (0-10) for rating the patients' enthusiasm for the UHF regimen and prioritization of the following treatment-related effects: treatment efficacy, acute/late adverse effects, physical/emotional/financial burden, and breast cosmesis. The patient and treatment characteristics were assessed by a physician. RESULTS: In total, 247 questionnaires were administered between November 2022 and June 2023. The age distribution was as follows: < 50:50 s:60 s: ≥ 70 = 59 (24%):76 (30%):63 (26%):49 (20%). Sixty-nine percent of patients rated their enthusiasm for the UHF regimen at ≥ 6 out of 10 points (45% rated 10/10). Treatment efficacy was the highest priority for most patients (89%), whereas breast cosmesis the lowest priority (53%). CONCLUSIONS: Patients' enthusiasm for UHF-WBI was observed across the cohort. These results could motivate researchers and clinicians to introduce UHF regimens in clinical practice.

RESUMEN

Congenital cytomegalovirus (cCMV) infection is the most common congenital infection in developed countries. Although a standard therapy has not yet been established, evidence for the management of cCMV infection has been accumulating. The first edition of the "Clinical Practice Guidelines for the Management of Congenital Cytomegalovirus Infection" was published in Japan in 2023. This summary outlines the clinical questions (CQs) in the guidelines, with reference to the Japanese Medical Information Distribution Service Manual. Overall, 20 CQs with statements regarding prenatal risk assessment, prevention and management at diagnosis (CQs 1-1-1-3), diagnosis (CQs 2-1-2-6), treatment (CQs 3-1-3-7) and follow-up requirements (CQs 4-1-4-4) have been discussed. For each statement, the levels of recommendation, evidence and consensus rates were determined. These guidelines will assist in the management of patients with cCMV infection.

RESUMEN

BACKGROUND: In older patients, esophageal squamous cell carcinoma (ESCC) is difficult to treat using standard therapies, including surgery and cisplatin-based chemoradiotherapy. Paclitaxel (PTX) has radiosensitizing activity. We conducted a phase I trial of PTX combined with radiotherapy to establish a standard therapy for locally advanced ESCC in older patients. METHODS: Enrollment was conducted at six centers in Japan from April 2016 to September 2019. The participants were aged ≥ 70 years, had locally advanced ESCC, and were intolerant to surgery or unwilling. A fixed 60-Gy radiation dose was administered in 30 fractions. PTX dosing levels started at 30 mg/m2 weekly for 6 weeks. Depending on the number of DLTs, the dose was set to be increased by 10 mg/m2 or switched to biweekly. A geriatric assessment was performed before treatment using the Geriatric-8 screening tool. The primary endpoint was dose-limiting toxicity (DLT). RESULTS: We enrolled 24 patients (6 per group); DLT was observed in one (grade 4 hypokalemia), one (grade 3 aspiration), two (grade 3 radiodermatitis, grade 3 esophageal hemorrhage), and two (grade 3 anorexia, grade 5 pneumonitis) patients in the weekly PTX 30, 40, 50, and 60 mg/m2 groups, respectively. All adverse events, except death in the 60 mg/m2 group, showed reversible improvement, and the safety profile was considered acceptable. The 2-year survival and complete response rates were 40.0% and 54.2%, respectively. There was a significant difference in survival between favorable and unfavorable Geriatric-8 scores. CONCLUSIONS: The recommended PTX dose with concomitant radiation was determined to be 50 mg/m2 weekly. Phase II trials at this dose are underway.

RESUMEN

Pancreatic cancer remains a highly lethal disease with a 5-year survival proportion of <10%. Chemoradiotherapy is a treatment option for unresectable locally advanced (UR-LA) or borderline resectable (BR) pancreatic cancer, but its efficacy is not sufficient. Induction of the synergistic effect of irradiation and immune checkpoint inhibitors can be an attractive strategy. An open-label randomized phase III trial has been conducted since October 2020 to confirm the superiority of nivolumab plus S-1-based chemoradiotherapy over S-1-based chemoradiotherapy alone in patients with UR-LA or BR pancreatic cancer. A total of 216 patients will be enrolled in 14 institutions within 3.5 years. The primary endpoint of the safety run-in part is dose-limiting toxicity, and that of the phase III part is overall survival. This trial was registered at the Japan Registry of Clinical Trials as jRCT2080225361 (https://jrct.niph.go.jp/latest-detail/jRCT2080225361).

RESUMEN

BACKGROUND: Neoadjuvant therapy is the standard treatment for patients with locally advanced oesophageal squamous cell carcinoma (OSCC). However, the prognosis remains poor and more intensive neoadjuvant treatment might be needed to improve patient outcomes. We therefore aimed to compare the efficacy and safety of neoadjuvant doublet chemotherapy, triplet chemotherapy, and doublet chemotherapy plus radiotherapy in patients with previously untreated locally advanced OSCC. METHODS: In this randomised, open-label, phase 3 trial, patients aged 20-75 years with previously untreated locally advanced OSCC and an Eastern Cooperative Oncology Group performance status of 0 or 1 were recruited from 44 centres across Japan. Patients were randomly assigned (1:1:1) centrally via a web-based system to receive neoadjuvant doublet chemotherapy (two courses of fluorouracil [800 mg/m2 per day intravenously on days 1-5] and cisplatin [80 mg/m2 per day on day 1] separated by an interval of 3 weeks [NeoCF]), triplet chemotherapy (three courses of fluorouracil [750 mg/m2 per day on days 1-5], cisplatin [70 mg/m2 per day on day 1], and docetaxel [70 mg/m2 per day on day 1] repeated every 3 weeks [NeoCF+D]), or doublet chemotherapy (two courses of fluorouracil [1000 mg/m2 per day on days 1-4] and cisplatin [75 mg/m2 per day on day 1] separated by an interval of 4 weeks) plus 41·4 Gy radiotherapy [NeoCF+RT]) followed by oesophagectomy with regional lymph node dissection. Randomisation was stratified by T stage and institution. Participants, investigators, and those assessing outcomes were not masked to group assignment. The primary endpoint was overall survival, analysed by intention to treat. Analysis of safety included all patients who received at least one course of chemotherapy, and analysis of surgical complications included those who also underwent surgery. This study is registered with the Japan Registry of Clinical Trials, jRCTs031180202, and the trial is complete. FINDINGS: A total of 601 patients (529 male individuals and 72 female individuals) were randomly assigned between Dec 5, 2012, and July 20, 2018, with 199 patients in the NeoCF group, 202 patients in the NeoCF+D group, and 200 patients in the NeoCF+RT group. Compared with the NeoCF group, during a median follow-up period of 50·7 months (IQR 23·8-70·7), the 3-year overall survival rate was significantly higher in the NeoCF+D group (72·1% [95% CI 65·4-77·8] vs 62·6% [55·5-68·9]; hazard ratio [HR] 0·68, 95% CI 0·50-0·92; p=0·006) but not in the NeoCF+RT group (68·3% [61·3-74·3]; HR 0·84, 0·63-1·12; p=0·12). Grade 3 or higher febrile neutropenia occurred in two (1%) of 193 patients in the NeoCF group, 32 (16%) of 196 patients in the NeoCF+D group, and nine (5%) of 191 patients in the NeoCF+RT group. Treatment-related adverse events leading to termination of neoadjuvant therapy were more common in the NeoCF+D group (18 [9%] of 202 participants) than in the NeoCF+RT group (12 [6%] of 200) and NeoCF group (eight [4%] of 199). There were three (2%) treatment-related deaths during neoadjuvant therapy in the NeoCF group, four (2%) deaths in the NeoCF+D group, and two (1%) deaths in the NeoCF+RT group. Grade 2 or higher postoperative pneumonia, anastomotic leak, and recurrent laryngeal nerve paralysis were reported in 19 (10%), 19 (10%), and 28 (15%) of 185 patients, respectively, in the NeoCF group; 18 (10%), 16 (9%), and 19 (10%) of 183 patients, respectively, in the NeoCF+D group; and 23 (13%), 23 (13%), and 17 (10%) of 178 patients, respectively, in the NeoCF+RT group. The in-hospital deaths following surgery included three deaths in the NeoCF group, two deaths in the NeoCF+D group, and one in the NeoCF+RT group. INTERPRETATION: Neoadjuvant triplet chemotherapy followed by oesophagectomy resulted in a statistically significant overall survival benefit compared with doublet chemotherapy and might be the new standard of care for locally advanced OSCC who are in good condition in Japan. Neoadjuvant doublet chemotherapy plus radiotherapy did not show significant improvement of survival compared with doublet chemotherapy.

RESUMEN

PURPOSE: This study aimed to investigate the potential of a newly developed small electrode to accurately record muscle activity during swallowing. MATERIAL AND METHODS: This study included 31 healthy participants. The participants underwent swallowing trials with three types of material. The recordings involved the following conditions: 1) swallowing saliva, 2) swallowing 3 mL water, and 3) swallowing 5 mL water. Two types of electrodes, a conventional electrode (CE) and a newly developed small electrode (NE), were symmetrically positioned on the skin over the suprahyoid muscle group, starting from the center. From the surface electromyography data, the swallowing duration (s), peak amplitude, and rising time (duration from swallowing onset to peak amplitude: s) were measured. Additionally, the equivalence of characteristics of the waveform of muscle activities was calculated by using the variance in both the upper and lower confidence limits in duration and rising time. RESULTS: No significant differences in baseline, swallowing duration or rising time between the CE and NE were observed for any swallowing material. The peak amplitude was significantly higher for the NE than for the CE for all swallowing materials. The CE and NE displayed no significant difference in the equivalence of characteristics of the waveform of muscle activities for any swallowing material. CONCLUSIONS: The gold-plated small electrodes utilized in this study indicated the ability to record the same characteristics of muscle activity as conventional electrodes. Moreover, it was able to capture the muscle activity of each muscle group with improved sensitivity in a narrow area, such as under the submandibular region, with more precision than that of conventional electrodes.

RESUMEN

Monitoring Epstein-Barr virus (EBV) and cytomegalovirus (CMV) infection after transplantation is recommended to enable preemptive therapy. However, the most suitable sample type remains unclear. Patients who underwent hematopoietic stem cell or liver transplantation were included in this study. Viral loads in sequential whole-blood and plasma samples were retrospectively analyzed. EBV DNA was detected more frequently in whole blood (55%) than in plasma (18%). The detection rate of CMV DNA was similar between the two sample types. The correlation of viral loads between the two sample types were 0.515 and 0.688 for EBV and CMV, respectively. Among paired samples in which EBV DNA was detected in whole blood, the plasma EBV detection rate was significantly higher in patients who underwent hematopoietic stem cell transplantation than in those who underwent liver transplantation. The viral DNA load in whole blood and plasma showed similar trends. The EBV detection rate was higher in whole blood, and a high correlation was observed between CMV DNA loads and whole blood and plasma. These results indicate that whole blood is more sensitive for monitoring both EBV and CMV, whereas plasma is a potential alternative sample for monitoring CMV.

RESUMEN

Epstein-Barr virus (EBV) infection can lead to infectious mononucleosis (EBV-IM) and, more rarely, EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH), which is characterized by a life-threatening hyperinflammatory cytokine storm with immune dysregulation. Interferon-gamma (IFNγ) has been identified as a critical mediator for primary HLH; however, the detailed role of IFNγ and other cytokines in EBV-HLH is not fully understood. In this study, we used single-cell RNA sequencing to characterize the immune landscape of EBV-HLH and compared it with EBV-IM. Three pediatric patients with EBV-HLH with different backgrounds, one with X-linked lymphoproliferative syndrome type 1 (XLP1), two with chronic active EBV disease (CAEBV), and two patients with EBV-IM were enrolled. The TUBA1B + STMN1 + CD8 + T cell cluster, a responsive proliferating cluster with rich mRNA detection, was explicitly observed in EBV-IM, and the upregulation of SH2D1A-the gene responsible for XLP1-was localized in this cluster. This proliferative cluster was scarcely observed in EBV-HLH cases. In EBV-HLH cases with CAEBV, upregulation of LAG3 was observed in EBV-infected cells, which may be associated with an impaired response by CD8 + T cells. Additionally, genes involved in type I interferon (IFN) signaling were commonly upregulated in each cell fraction of EBV-HLH, and activation of type II IFN signaling was observed in CD4 + T cells, natural killer cells, and monocytes but not in CD8 + T cells in EBV-HLH. In conclusion, impaired responsive proliferation of CD8 + T cells and upregulation of type I IFN signaling were commonly observed in EBV-HLH cases, regardless of the patients' background, indicating the key features of EBV-HLH.

RESUMEN

Congenital cytomegalovirus (cCMV) infection can damage the central nervous system in infants; however, its prognosis cannot be predicted from clinical evaluations at the time of birth. Urinary exosomes can be used to analyze neuronal damage in neuronal diseases. To investigate the extent of neuronal damage in patients with cCMV, exosomal miRNA expression in the urine was investigated in cCMV-infected infants and controls. Microarray analysis of miRNA was performed in a cohort of 30 infants, including 11 symptomatic cCMV (ScCMV), 7 asymptomatic cCMV (AScCMV), and one late-onset ScCMV cases, and 11 healthy controls (HC). Hierarchical clustering analysis revealed the distinct expression profile of ScCMV. The patient with late-onset ScCMV was grouped into the ScCMV cluster. Pathway enrichment analysis of the target mRNAs differed significantly between the ScCMV and HC groups; this analysis also revealed that pathways related to brain development were linked to upregulated pathways. Six miRNAs that significantly different between groups (ScCMV vs. HC and ScCMV vs. AScCMV) were selected for digital PCR in another cohort for further validation. Although these six miRNAs seemed insufficient for predicting ScCMV, expression profiles of urine exosomal miRNAs can reveal neurological damage in patients with ScCMV compared to those with AcCMV or healthy infants.

INTRODUCTION: Insurance coverage for oral valganciclovir (VGCV) began in Japan in April 2023 on the basis of results, including our clinical trials for symptomatic congenital cytomegalovirus (CMV) disease. The VGCV treatment is available throughout Japan, so clinicians must consider the likelihood of hearing improvement and the possibility of neutropenia before dosing. MATERIALS AND METHODS: We performed a substudy of an investigator-initiated, single-arm, prospective, multicenter, clinical trial in which 24 infants with symptomatic congenital CMV disease were orally administered 16 mg/kg VGCV twice daily for 6 months as an intervention. We examined the infants' baseline characteristics associated with improved hearing impairment or a severely reduced neutrophil count. RESULTS: Of the 24 patients, 4 had normal hearing on assessment of their ear with the best hearing. Hearing impairment improved in 14 patients and did not respond to VGCV treatment in 6 patients at the 6-month hearing assessment. CMV DNA levels in plasma at baseline were higher in patients in whom hearing did not respond to treatment. A neutrophil count <500/mm3 occurred in 5 (21%) patients for the first 6 weeks and in 8 (33%) patients for the first 6 months. A neutrophil count at screening and the lowest neutrophil count over the 6 months showed the highest correlation (r = 0.477, p = 0.019). CONCLUSIONS: Infants with a low plasma viral load at screening tend to have an improvement in hearing impairment. Clinicians should be aware of neutropenia during VGCV treatment particularly in patients with a low neutrophil count during screening.

RESUMEN

Background: Coronavirus disease 2019 (COVID-19) features a hypercoagulable state, but therapeutic anticoagulation effectiveness varies with disease severity. We aimed to evaluate the dynamics of the coagulation profile and its association with COVID-19 severity, outcomes, and biomarker trajectories. Methods: This multicenter, prospective, observational study included patients with COVID-19 requiring respiratory support. Rotational thromboelastometry findings were evaluated for coagulation and fibrinolysis status. Hypercoagulable status was defined as supranormal range of maximum clot elasticity in an external pathway. Longitudinal laboratory parameters were collected to characterize the coagulation phenotype. Results: Of 166 patients, 90 (54%) were severely ill at inclusion (invasive mechanical ventilation, 84; extracorporeal membrane oxygenation, 6). Higher maximum elasticity (P=0.02) and lower maximum lysis in the external pathway (P=0.03) were observed in severely ill patients compared with the corresponding values in patients on non-invasive oxygen supplementation. Hypercoagulability components correlated with platelet and fibrinogen levels. Hypercoagulable phenotype was associated with favorable outcomes in severely ill patients, while normocoagulable phenotype was not (median time to recovery, 15 days vs. 27 days, P=0.002), but no significant association was observed in moderately ill patients. In patients with severe COVID-19, lower initial C3, minimum C3, CH50, and greater changes in CH50 were associated with the normocoagulable phenotype. Changes in complement components correlated with dynamics of coagulation markers, hematocrit, and alveolar injury markers. Conclusions: While hypercoagulable states become more evident with increasing severity of respiratory disease in patients with COVID-19, normocoagulable phenotype is associated with triggered by alternative pathway activation and poor outcomes.

RESUMEN

Primary Epstein-Barr virus (EBV) infection occasionally causes EBV-infectious mononucleosis (EBV-IM) and EBV-hemophagocytic lymphohistiocytosis (EBV-HLH). Although EBV-IM is mostly mild and self-limiting, EBV-HLH is a life-threatening disease characterized by excessive immune activation. However, the pathogenesis of EBV-HLH is yet to be fully elucidated. A diagnostic biomarker for EBV-HLH is desirable because early diagnosis and treatment are critical for the effective management of patients. In this study, the proteomic profiling of plasma was performed using liquid chromatography-mass spectrometry to identify proteins specific to EBV-IM and EBV-HLH. Furthermore, pathway analysis was performed for the proteins upregulated in patients with EBV-IM and EBV-HLH. Compared to healthy controls, 63 and 18 proteins were upregulated in patients with EBV-IM and EBV-HLH, respectively. Pathway and process enrichment analyses revealed that the complement system was the most enriched category of upregulated proteins in EBV-IM, whereas proteins related to immune effector processes were the most enriched in EBV-HLH. Among the 18 proteins upregulated in EBV-HLH, seven were exclusive to EBV-HLH. These specific proteins were associated with three pathways, and apolipoprotein E was commonly found in all the pathways. Proteomic analysis may provide new insights into the host response to EBV infection and the pathogenesis of EBV-related diseases.

RESUMEN

Oesophageal squamous cell carcinoma is a common malignancy worldwide. Definitive chemoradiotherapy is the standard treatment for patients with resectable stage oesophageal squamous cell carcinoma who cannot undergo surgery, as well as those with locally advanced unresectable oesophageal squamous cell carcinoma. However, it has several disadvantages such as poor survival, radiation-related toxicities and severe and lethal complications related to salvage treatment for residual or recurrent disease. Numerous clinical trials on chemoradiotherapy have been conducted to confirm the optimal combination of irradiation and chemotherapy. For advanced disease, multimodal treatment strategies including salvage surgery are essential. Palliative chemoradiotherapy is also crucial for dysphagia in locally advanced oesophageal squamous cell carcinoma with or without metastatic lesions. Recently, the synergistic mechanism of radiotherapy combined with immunotherapy has been reported. Early phase clinical trials suggest that a combination of immunotherapy and chemoradiotherapy can improve clinical outcomes with manageable side effects, but further investigations are needed. Here, we reviewed the existing clinical data and current development of chemoradiotherapy combined with immunotherapy in patients with oesophageal squamous cell carcinoma.
