Effect of the number of negative lymph nodes removed on the survival and recurrence rate after gastrectomy in patients with gastric cancer: a multicenter retrospective cohort study

BackgroundVarious factors affect the survival rate of Gastric cancer (GC) patients after gastrectomy. This study aimed to investigate the effect of the number of negative lymph nodes (NLNs) removed on GC patients’ survival and recurrence rate after gastrectomy.MethodsIn this retrospective, multicenter cohort study, we reviewed the medical profile of 639 patients with a definite diagnosis of GC who underwent gastrectomy from 2010 to 2022 in one of the medical centers affiliated with the Iran University of Medical Sciences. Based on the number of NLNs removed, patients were divided into three groups, including (0–9NLNs), (10–15 NLNs), and (≥ 16 NLNs), including 155, 231, and 253 GC patients, respectively. Demographic characteristics, tumor characteristics, and pathological findings of the patients were extracted by referring to the patient’s files.ResultsThe 5-year survival rate of patients was estimated at 48.2%. The 5-year tumor recurrence rate in patients with the number of NLNs 1–9, NLNs 10–15, and ≥ 16 NLNs were 79.4%, 51.1%, and 30.8%, respectively. (Log-rank = 9.24, P 0.001) The multivariate analysis showed that the 5-year survival rate in patients with fewer NLNs removed ≥ 16 was significantly higher than in the other two groups. In addition, age, BMI, tumor size, tumor stage, metastasis, and tumor differentiation were significantly related to the survival of GC patients after gastrectomy. (p < 0.05)ConclusionPaying attention to the number of NLNs removed during gastrectomy can be a key factor in improving the survival prediction of GC patients.

Toremifene, an Alternative Adjuvant Endocrine Therapy, Is Better Than Tamoxifen in Breast Cancer Patients with CYP2D6*10 Mutant Genotypes.

Tamoxifen showed individual differences in efficacy under different CYP2D6*10 genotypes. Our study evaluated the prognosis of tamoxifen or toremifene in hormone receptor (HR)-positive breast cancer patients under different genotypes. CYP2D6*10 genotypes of HR-positive breast cancer patients were determined by Sanger sequencing, and all the patients were divided into tamoxifen group or toremifene group. A total of 268 patients with HR-positive breast cancer were studied. The median follow-up time was 72.0 months (range, 5.0 to 88.0 months). Of these, 88 (32.9%), 114 (42.5%), and 66 (24.6%) patients had C/C, C/T, and T/T genotypes, respectively. Among patients who received tamoxifen (n=176), the 5-year disease-free survival (DFS) rate in patients with C/C and C/T genotype was better than that in patients with T/T genotype, and the difference was statistically significant (p < 0.001 and p=0.030, respectively). In patients receiving toremifene, CYP2D6*10 genotype was not significantly associated with DFS (p=0.325). Regardless of genotypes, the 5-year DFS rate was higher in patients treated with toremifene than in patients with tamoxifen (91.3% vs. 80.0%, p=0.011). Compared with tamoxifen, toremifene remained an independent prognostic marker of DFS in multivariate analysis (hazard ratio, 0.422; p=0.021). For all the 180 patients with CYP2D6*10 C/T and T/T genotypes, the 5-year DFS rate was significantly higher in the toremifene group than in the tamoxifen group (90.8% vs. 70.1%, p=0.003). Toremifene may be an alternative adjuvant endocrine therapy for patients with CYP2D6*10 mutant genotypes.

Clinical score for colorectal cancer patients with lung-limited metastases undergoing surgical resection: Meta-Lung Score

BackgroundRadical resection of isolated lung metastases (LM) from colorectal cancer (CRC) is debated. Like Fong’s criteria in liver metastases, our study was meant to assign a clinical prognostic score in patients with LM from CRC, aiming for better surgery selection. MethodsWe retrospectively analyzed data from 260 CRC patients who underwent curative LM resection from December 2002 to January 2022, verifying the impact of different clinicopathological features on the overall survival (OS). ResultsAt the univariate analysis: higher baseline CEA levels (p = 0.0001), disease-free survival less than or equal to 12 months (m) (p = 0.0043), LM size larger than 2 cm (p = 0.0187), multiple resectable nodules (p = 0.0083), and positive nodal status of the primary tumor (p = 0.0011) were associated with worse prognosis. In a Cox regression model, these characteristics retained their independent role for OS (p < 0.0001) and were chosen as criteria to be assigned one point each for clinical risk score. The 5-year survival rate in patients with 0 points was 88%, while no patients with a 5-point score survived at 2 years. Based on the 0–1 vs. 2–5 score range, we obtained a significant difference in median OS: not reached vs. 40.8 months (95 %CI 36 to 87.5), respectively (p < 0.0001) stratifying patients into good and poor prognosis. The prognostic role of the score was also confirmed in terms of median RFS: not reached in 0–1 scored patients vs. 30.5 months (95 %CI 19.4 to 42) in patients with 2–5 scores (p = 0.0006). ConclusionsWhen LM from CRC is resectable, the Meta-Lung Score provides valuable prognostic information. Indeed, while upfront surgery should be considered in patients with scores of 0 to 1, it should be cautiously suggested in patients with scores of 2 to 5, for whom a prognosis comparison between preventive surgery and other treatments should be investigated in prospective randomized clinical trials.

Minichromosome maintenance proteins in lung adenocarcinoma: Clinical significance and therapeutic targets.

Lung cancer is the most common cause of cancer-related death worldwide, accounting for 1.8 million deaths annually. Analysis of The Cancer Genome Atlas data showed that all members of the minichromosome maintenance (MCM) family (hexamers involved in DNA replication: MCM2-MCM7) were upregulated in lung adenocarcinoma (LUAD) tissues. High expression of MCM4 (P = 0.0032), MCM5 (P = 0.0032), and MCM7 (P = 0.0110) significantly predicted 5-year survival rates in patients with LUAD. Simurosertib (TAK-931) significantly suppressed the proliferation of LUAD cells by inhibiting cell division cycle 7-mediated MCM2 phosphorylation. This finding suggested that MCM2 might be a therapeutic target for LUAD. Moreover, analysis of the epigenetic regulation of MCM2 showed that miR-139-3p, miR-378a-5p, and miR-2110 modulated MCM2 expression in LUAD cells. In patients with LUAD, understanding the role of these miRNAs may improve prognoses.

Outcome of rare primary malignant bone sarcoma treated with multimodal therapy: Results from the EUROpean Bone Over 40 Sarcoma Study (EURO-B.O.S.S.).

Rare primary malignant bone sarcomas (RPMBS) account for 5%-10% of primary high-grade bone tumors and represent a major treatment challenge. The outcome of patients with RPMBS enrolled in the EUROpean Bone Over 40 Sarcoma Study (EURO-B.O.S.S) is presented. Inclusion criteria were as follows: age from 41 to 65years and a diagnosis of high-grade spindle cell, pleomorphic, or vascular RPMBS. The chemotherapy regimen included doxorubicin 60mg/m2 , ifosfamide 9g/m2 , and cisplatin 90mg/m2 ; postoperative methotrexate 8g/m2 was added in case of a poor histologic response. Version 2.0 of the Common Terminology Criteria for Adverse Events, Kaplan-Meier curves, log-rank tests, and univariate Cox regression models were used. In total, 113 patients were evaluable for analysis. The median patient age was 52years (range, 40-66 years), and 67 patients were men. Eighty-eight tumors were categorized as undifferentiated pleomorphic sarcomas (UPS), 20 were categorized as leiomyosarcomas, three were categorized as fibrosarcomas, and two were categorized as angiosarcomas. Eighty-three of 113 tumors were located in the extremities. Ninety-five of 113 patients presented with no evidence of metastases. After a median follow-up of 6.8years (interquartile range [IQR], 3.5-9.8 years), the 5-year overall survival rate for patients with localized disease was 68.4% (IQR, 56.9%-77.5%), and it was 71.7% (IQR, 58.1%-81.6%) for patients with UPS and 54.9% (IQR, 29.5%-74.5%) for patients with leiomyosarcoma. Grade III-IV hematologic toxicity was reported in 81% patients; 23% had grade II-III neurotoxicity, and 37.5% had grade I-II nephrotoxicity. Five-year overall survival was significantly better for patients with localized disease, for patients who obtained surgical complete remission, and when the primary tumor was located in the extremities. The survival of patients who had RPMBS in the current series was similar to that of age-matched patients who had high-grade osteosarcoma treated according to the same protocol. An osteosarcoma-like chemotherapy may be proposed in patients who have RPMBS.

Comparative Analysis of Donor Liver Allograft Outcomes in Hepatocellular Carcinoma Patients Who Underwent Liver Transplant.

Liver transplant for patients with hepatocellular carcinoma involves 3 main types of donor allografts: donation after brain death, donation after cardiac death, and donation after brain and cardiac death. Data on this topic are limited, and controversies exist regarding liver transplant outcomes in hepatocellular carcinoma patients who have received these allografts. Data from 490 hepatocellular carcinoma patients who received liver transplant from 2015 to 2021 at the Shulan (Hangzhou) Hospital were retrospectively analyzed. Participants were divided into 3 cohorts according to allograft type: donation after brain death, donation after cardiac death, and donation after brain and cardiac death. Kaplan-Meier and Cox regression methods were used to evaluate patient survival, graft survival, and recurrence-free survival rates after liver transplant. Kaplan-Meier analysis revealed that 3-year patient survival rates were 69.2% for donations after brain death, 69.2% for donations after cardiac death, and 46.6% for donations after brain and cardiac death (P = .42); the 3-year graft survival rates were 53.3% for donations after brain death, 56.4% for donations after cardiac death, and 46.6% for donations after brain and cardiac death (P = .44); and 3-year recurrence-free survival rates were 55% for donations after brain death, 56.6% for donations after cardiac death, and 39.5% for donations after brain and cardiac death (P = .46). Complications were also similar across the 3 cohorts (P = .36). Multivariable analysis showed that intraoperative red blood cell transfusion (hazard ratio: 1.820; P = .042) and early allograft dysfunction (hazard ratio: 3.240; P = .041) were independent risk factors for graft survival. Similar outcomes can be achieved for hepatocellular carcinoma patients who undergo liver transplant with donations after brain death, donations after cardiac death, or donations after brain and cardiac death allografts, especially when strict donor selection criteria are applied.

Palliative Care Case Report: A Man with End Stage Lung Cancer with Brain Metastases

INTRODUCTION : Lung cancer accounts for 13% of malignancies in the world and the most common type of cancer suffered by men in Indonesia. The 5-year survival rate for patients with lung cancer is only 18.1%. About 25-30% will develop brain metastases. Overall palliative care is needed including biologically targeted therapy, chemotherapy, stereotactic radiosurgery (SRS), surgery in selected cases, and whole brain radiotherapy treatment (WBRT). Rare studies that take into account surgical palliation in advanced NSCLC. It has been demonstrated that metastaticectomy generally improves survival and, in some patients, even long-term survival. CASE REPORT : A 65-year-old male patient with Non-Small Cell Carcinoma favor Lung Adenocarcinoma and cerebellum metastases. The patient underwent surgery to remove a brain tumor. The patient received 8 radiotherapies and Erlotinib chemotherapy for 4 cycles for 6 months. The dose of Erlotinib 150g/24 hours was used in the first month. The dose was reduced in the 2nd to 6th month to 100g/24 hours. Assessment of palliative care was carried out using the Karnopsky Questionnaire, Fatigue Severity Scale (FSS), and Palliative Performance Scale (PPS). CONCLUSION : . Despite major improvements in the way lung cancer patients are treated in recent years, morbidity and death rates are still high. Palliative care (PC) is an approach to treating patients with life-threatening diseases, one of which is lung cancer

Long-lasting Limb Salvage After Malignant Femoral-Bone Tumor Resection Reconstructed With a Thin-mantle Titanium Stem Fixated With Cement.

The purpose of the present study was to review and report clinical outcomes of the Kyocera Modular Limb Salvage System (KMLS) using a thin-mantle titanium stem fixated with cement, for reconstruction after resection of malignant femoral-bone tumors. Twenty consecutive patients who had undergone reconstruction using the KMLS with cemented thin-mantle titanium stem fixation between July 2010 and December 2019 at Ryukyu University Hospital were included. We retrospectively collected the following data: age, sex, follow-up period, tumor location, histological diagnosis, stem size, overall implant survival, radiolucency, postoperative complications, overall survival, and oncological survival. The median follow-up period was 63 months (range=10.7-261 months). The bone tumors were in the proximal part of the femur in 9 patients and in the distal part of the femur in 11 patients. The 5-year overall implant survival rate was 90.9% among surviving patients. A revision surgery was required for only one patient (5%), due to infection. Radiolucency, due to an instability of the implant, was observed in 7 out of 20 patients: 6 patients with distal femoral reconstruction, and 1 patient with proximal femoral reconstruction. However, none of the patients complained of any symptoms or required revision surgeries at the last follow-up. The 5-year overall patient-survival rate was 67.6%. The KMLS with cemented thin-mantle titanium stem fixation for femoral bone reconstruction after resection for bone malignancy resulted in long-term patient benefit.

Epidemiology and Outcomes of Children with Kidney Failure Receiving Kidney Replacement Therapy in Australia and New Zealand

The incidence and outcomes of kidney replacement therapy (KRT) have been well-studied in adults, but much less so in children. This study aimed to investigate the epidemiology and outcomes of KRT in children in Australia and New Zealand from 2000 to2020. Children aged<18 years initiating KRT in Australia and New Zealand between January 1, 2000 and December 31, 2020 and reported to the Australia and New Zealand Dialysis and Transplant Registry were included. Patient survival, technique-survival, and graft survival were analyzed by Cox regression analyses. Overall, 1058 children (median [interquartile range (IQR)] age 11 [5-15] years, 41% female, 66% White) were followed-up with for a median period of 12.3 years. First KRT modalities were peritoneal dialysis (PD; 48%), hemodialysis (HD; 34%), and kidney transplantation (KT; 18%). Pre-emptive KT incidence was highest in Caucasian children (80.4%) and lowest in the Indigenous population (3.2%). There was no difference in 5-year patient survival rates between 2011 and 2020 (96.9%, 95% confidence interval [CI] 93.8-98.4) and the preceding decade, 2000-2010 (94.5%, 95% CI 90.4-96.8) (P= 0.79). There was no difference in 5-year death-censored technique survival between 2011 and 2020 (51.2%, 95% CI 39.1-62) and 2000-2010 (48.8%, 95% CI 40.5-56.6) (P= 0.27). However, 5-year derath-censored graft survival was significantly higher in 2011-2020 (88.4%, 95% CI 84.6-91.4) than in 2000-2010 (84.3%, 95% CI 80.4-87.5) (P< 0.001). PD is the most commonly prescribed KRT modality for children in Australia and New Zealand. Patient-survival, technique-survival, and graft survival rates are excellent and graft survival has improved over the last 2 decades.

Coil-assisted ethanol embolotherapy for refractory head and neck arteriovenous malformations with Onyx recrudescence: 10-Year experiences

ObjectiveThis study aimed to evaluate the outcomes of coil-assisted ethanol embolotherapy in recanalized head and neck arteriovenous malformations (HNAVMs) with dilated outflowing veins after Onyx treatment. MethodsThirty-six patients with HNAVMs (18 females and 18 males with a mean age of 26.83 years) who experienced recurrence after Onyx embolization from October 2007 to October 2017 were included in this study. All patients underwent complete clinical and angiographic examinations. Further, each patient was classified based on the Schobinger stage before undergoing staged ethanol embolization. All patients were followed up for 5 years in-person at an interval of 3 months after discharge. The Kaplan-Meier method was used to perform the recurrence-free survival analysis. ResultsSixteen patients (44.4%) had Schobinger stage II HNAVMs, and the remaining patients had Schobinger stage III or IV (20/36 patients [55.6%]) HNAVMs. A total of 116 embolization procedures were performed, coils were applied in 107 procedures (92.2%) among patients with dilated outflowing veins. The dose of absolute ethanol was 16.39 mL per procedure in patients with Schobinger II HNAVMs, and 22.45 mL per procedure in patients with Schobinger III and IV HNAVMs (P = .024, 95% confidence interval, 1.128-5.009). During the 3-month evaluation, complete response was observed in 13 of 36 patients (36.1%), and partial response was observed in 23 of 36 patients (63.9%). The 5-year recurrence-free survival rate for patients who underwent Onyx treatment had improved 58.3% after ethanol embolization (95% confidence interval, 2.853-9.595; P < .0001). ConclusionsCoil-assisted ethanol embolotherapy could treat refractory HNAVMs with Onyx recrudescence effectively.

Neoadjuvant chemoradiotherapy followed by oesophagectomy may be the optimal treatment option for lower thoracic oesophageal cancer with supraclavicular lymph node metastasis: An inverse probability of treatment-weighted analysis of SEER database.

Whether supraclavicular lymph node (SCLN) metastasis in patients with oesophageal cancer belongs to regional disease is controversial, leading to heterogeneity in clinical treatment decisions. This study aimed to determine the optimal treatment for lower thoracic oesophageal cancer (LTOC) with SCLN metastasis. Patients with LTOC registered in the Surveillance, Epidemiology, and End Results database during 2010-2015 were identified. Selected patients were grouped according to disease spread as those with locoregional disease, with SCLN metastasis or with distant metastasis, as well as according to treatment modality (neoadjuvant chemoradiotherapy followed by surgery (nCRT+S group), upfront surgery ± adjuvant therapy (upfront S group) and definitive chemoradiotherapy (dCRT group)). The Cox regression analysis and inverse probability of treatment weighting (IPTW) were used to identify the optimal treatment modality for different groups. Of 11,767 LTOC patients identified from the database, the 5-year overall survival (OS) rates for patients with the locoregional disease (n = 7,541), SCLN metastasis (n = 120) and distant metastasis (n = 4,106) were 28.3%, 10.0% and 3.0%, respectively (P < 0.001). Among patients with SCLN metastasis, median OS in the nCRT+S, upfront S and dCRT groups were 25, 14 and 8 months, respectively (P < 0.001). After IPTW, the nCRT+S group was still associated with better median OS compared with other groups. The multivariate analysis identified treatment modality as an independent prognostic factor for OS. Neoadjuvant chemoradiotherapy followed by oesophagectomy may be the optimal treatment modality for LTOC with SCLN metastasis. The findings of this study need to be validated in large prospective studies.

Factors Influencing Hemodialysis Patients Survival Using Frailty Models

Abstract Background and objection: Hemodialysis is the most common renal replacement therapy in patients with End Stage Renal Disease (ESRD). This study investigated the 5-year survival rate of hemodialysis patients admitted to Imam Khomeini and Fatima Zahra Hospitals in Sari. Materials &amp; Methods: This study was performed on 335 patients on hemodialysis referring to Imam Khomeini and Fatima Zahra Hospitals from November 2008 to November 2013. To investigate the factors influencing the patients' survival rate, we used Cox model and Frailty model and compared these models efficiency, we also applied the Akaikie information criterion and the residuals review. All calculations have been performed with SPSS version 20 &amp; STATA version 8 and the significance level was 0.05. Findings: The results of this study showed that applying the Kaplan– Meier method to determine one, three and five year’s survival rates for hemodialysis patients were 74.9%, 53.2% and 20.4%, respectively. The mean survival time was 37.241 months. In the final model, in multivariate analysis of the gamma frailty model, the variables as age, education, marital status, diabetes, Kidney stone &amp; obstructions, the clinic, the mean serum albumin and urea have been identified as the most important predictors in hemodialysis patients' survival (p &lt; 0.05). Conclusion: According to the results of the frailty model fitness, the hemodialysis patients having the same explanatory variables also have different risk of death. Giving the Akaikie information criterion and the residuals review, the Weibull model with gamma frailty is more efficient than the Cox model and it has good fitness to the data.

ATP2C2 as a novel immune-related marker that defines the tumor microenvironment in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is an aggressive cancer that affects about 13/100,000 women yearly. Patients with TNBC are often resistant to endocrine and molecular targeted therapy, making clinical treatment challenging. Researches indicate that tumor microenvironment (TME) is related to prognosis in many cancers. Therefore, we aim to identify TME immune-related biomarkers to enhance the prognosis and immunotherapy efficacy in patients with TNBC. The bulk mRNA transcriptome data and clinical information of the (GSE58812) and (GSE25055) datasets were downloaded from the Gene Expression Omnibus (GEO) database, and the ESTIMATE algorithm was used to calculate the ImmuneScore, StromalScore, and ESTIMATEScore. Patients were divided into low and high groups according to the quartiles of ImmuneScore, StromalScore, and the median of ESTIMATEScore to filter differential expression genes (DEGs), respectively. The DEGs were then evaluated using univariate and multivariate Cox regression to identify TME-related genes and its association with survival rate for the construction of a TMErisk model with three biomarkers. Then Gene Expression Profiling Interactive Analysis (GEPIA) and The Cancer Genome Atlas (TCGA) data were used to compare the gene expression in cancer and normal tissues. xCell analysis calculated the proportion of tumor-infiltrating immune cells in low and high expression of ATPase Secretory Pathway Ca2+ Transporting 2 (ATP2C2). In addition, samples from 20 TNBC patients admitted to our institution were used for immunohistochemical (IHC) examination. Three immune-related DEGs were identified, including prolyl 3-hydroxylase 2 (P3H2), sodium voltage-gated channel beta subunit 3 (SCN3B), and ATP2C2 and a TMErisk model was constructed and validated. However, only ATP2C2 was selected for further analysis. ATP2C2 mRNA level of TNBC patients was higher than that of normal breast tissue. Survival analysis showed that patients with high expression of ATP2C2 had a bad prognosis. xCell analysis demonstrated that the expression of ATP2C2 was associated with 16 kinds of tumor-infiltrating immune cells. Protein expression of ATP2C2 in TNBC tissues was higher compared to paired normal tissues in IHC. This study constructed and validated a TMErisk model that can effectively predict 3- and 5-year survival rate for TNBC patients. TNBC patients with lower expression of ATP2C2 had a good prognosis.

Effect of Chinese Medicines combined with transarterial chemoembolization on primary hepatic carcinoma: A systematic review and meta-analysis.

To systematically evaluate the survival rate and postoperative adverse reactions of patients with hepatocellular carcinoma treated with traditional Chinese medicine combined with TACE by meta-analysis. Four major literature databases (Cochrane Library, Embase, PubMed, and Web of Science) were retrieved to collect published English articles since 2009. After determining the random effect model or fixed utility model based on a heterogeneity test, odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. This meta-analysis included 8 prospective studies published between 2009 and 2019. Due to moderate heterogeneity (P < .05, I2 = 54.8%), Therefore, the random effect model is used to analyze the data, so as to explore the relationship between CMs combined with TACE treatment and survival rate and postoperative adverse reactions. All the comprehensive test results show that there is a statistical significance between CMs combined with TACE treatment and survival rate. (OR = 1.88, 95% CI 1.34-2.64, P = .03). Then subgroup analysis and sensitivity analysis were carried out. The results indicated that the overall results ranged from 1.12(95% CI = 1.03-1.11) to 1.21(95% CI = 1.22-1.33). The 1-year survival rate of patients treated with traditional Chinese medicine TACE is a protective factor, and the quality score included in the study affects the evaluation of the effective dose. At the same time, traditional Chinese medicine combined with TACE has nothing to do with the reduction of postoperative complications.

Favorable outcomes in Hispanic recipients receiving simultaneous pancreas kidney transplantation.

The objective of this study was to compare the long-term outcomes of Hispanic versus white recipients who underwent simultaneous pancreas kidney transplantation (SPKT). This single-center study, conducted from 2003 to 2022, had a median follow-up of 7.5years. The study included 91 Hispanic and 202 white SPKT recipients. The mean age (44 vs. 46years), percentage of males (67% vs. 58%), and body mass index (BMI) (25.6 vs. 25.3kg/m2 ) were similar between the Hispanic and white groups. The Hispanic group had more recipients with type 2 diabetes (38%) compared to the white group (5%, p<.001). The duration of dialysis was longer in Hispanics (640 vs. 473days, p=.02), and fewer patients received preemptive transplants (10% vs. 29%, p<.01) compared to whites. Hospital length of stay, rates of BK Viremia, and acute rejection episodes within 1year were similar between the groups. The estimated 5-year kidney, pancreas, and patient survival rates were also similar between the groups, 94%, 81%, and 95% in Hispanics, compared to 90%, 79%, and 90% in whites. Increasing age and longer duration of dialysis were risk factors for death. Although Hispanic recipients had a longer duration on dialysis and fewer preemptive transplants, the survival rates were similar to those of white recipients. However, referring providers and many transplant centers continue to overlook pancreas transplants for appropriately selected patients with type 2 diabetes, particularly among minority populations. As a transplant community, it is crucial that we make efforts to comprehend and tackle these obstacles to transplantation.

Outcome of hematopoietic stem cell transplantation in pediatric patients with acute lymphoblastic leukemia not in remission enrolled in JACLS ALL-02.

Hematopoietic stem cell transplantation (HSCT) is only indicated for acute lymphoblastic leukemia (ALL) patients for whom other treatments are unlikely to be curative. However, outcomes of patients not in complete remission (CR) at HSCT remain very poor. To improve the outcomes of patients receiving HSCT, it is important to obtain detailed clinical information about patients with ALL receiving HSCT in CR and not in CR. Patients enrolled in the Japan Association of Childhood Leukemia Study ALL-02 who underwent HSCT and were not in CR (non-CR patients, n = 55) were examined. The 1-year overall survival (OS) rate of non-CR patients was 27.3%. Compared with CR patients, non-CR patients experienced very early and early relapse significantly more frequently and had poorer prognostic factors. Most interestingly, high hyperdiploid (HHD) patients showed an excellent 1-year OS of 80%. In addition, long-term survival among surviving HHD patients was longer than 5years. All eight patients who survived after undergoing HSCT while not in CR were younger than 10years at initial diagnosis and were negative for central nervous system involvement. While limited, these results suggest that a subset of patients may benefit from HSCT while not in CR.

Clinical Significance of Recurrence Risk Score for Conversion Surgery in Patients With Advanced Gastric Cancer.

To develop a recurrence risk score for determining the clinical indication for adjuvant chemotherapy in patients with initially unresectable advanced gastric cancer who underwent conversion surgery after chemotherapy. A total of 65 patients with stage IV gastric cancer who underwent conversion surgery after chemotherapy were retrospectively enrolled. We established a risk score based on clinicopathological factors related to recurrence after conversion surgery. Out of 65 patients, 40 (62%) had recurrence after conversion surgery. The 5-year overall survival rates in patients with and without recurrence were 14.4% and 87.1%, respectively (p<0.01). Multivariate logistic regression analysis identified the depth of tumor invasion (pT2-4) and histological tumor response (grade 0-1a) as an independent risk factor for disease recurrence (p=0.033 and p=0.048, respectively). A scoring system determined by these two factors was created; total score ranged from 0 to 2 points, and patients were categorized into three groups (scores of 0 vs. 1 vs. 2 points). This scoring system showed that 12 (18%), 15 (23%), and 38 (58%) patients had recurrence risk scores of 0, 1, and 2 points, respectively. There was a close relationship between a high score and the presence of tumor recurrence (p<0.01). Moreover, our model system had a high sensitivity for the prediction of recurrence, compared with the pathological stage. Recurrence risk score is a promising tool for assessing the need for adjuvant chemotherapy in patients with initially unresectable advanced gastric cancer after conversion surgery.

Prognosis of patients with systemic sclerosis-related interstitial lung disease on the lung transplant waiting list: a retrospective study

Advanced systemic sclerosis-associated interstitial lung disease (SSc-ILD) can be treated with lung transplantation. There is limited data on lung transplantation outcomes in patients with SSc-ILD, in non-Western populations.We assessed survival data of patients with SSc-ILD, on the lung transplant (LT) waiting list, and evaluated post-transplant outcomes in patients from an Asian LT center. In this single-center retrospective study, 29 patients with SSc-ILD, registered for deceased LT at Kyoto University Hospital, between 2010 and 2022, were identified. We investigated post-transplant outcomes in recipients who underwent LT for SSc-ILD, between February 2002 and April 2022. Ten patients received deceased-donor LT (34%), two received living-donor LT (7%), seven died waiting for LT (24%), and ten survived on the waiting list (34%). Median duration from registration to deceased-donor LT was 28.9 months and that from registration to living-donor LT or death was 6.5 months. Analysis of 15 recipients showed improved forced vital capacity with a median of 55.1% at baseline, 65.8% at 6 months, and 80.3% at 12 months post-transplant. The 5-year survival rate for post-transplant patients with SSc-ILD was 86.2%. The higher post-transplant survival rate at our institute than previously reported suggests that lung transplantation is acceptable in Asian patients with SSc-ILD.

CAR-NK cell therapy for glioblastoma: what to do next?

Glioblastoma is a malignant tumor with the highest morbidity and mortality in the central nervous system. Conventional surgical resection combined with radiotherapy or chemotherapy has a high recurrence rate and poor prognosis. The 5-year survival rate of patients is less than 10%. In tumor immunotherapy, CAR-T cell therapy represented by chimeric antigen receptor-modified T cells has achieved great success in hematological tumors. However, the application of CAR-T cells in solid tumors such as glioblastoma still faces many challenges. CAR-NK cells are another potential adoptive cell therapy strategy after CAR-T cells. Compared with CAR-T cell therapy, CAR-NK cells have similar anti-tumor effects. CAR-NK cells can also avoid some deficiencies in CAR-T cell therapy, a research hotspot in tumor immunity. This article summarizes the preclinical research status of CAR-NK cells in glioblastoma and the problems and challenges faced by CAR-NK in glioblastoma.

Integrated Analysis of the RASH Study with the Use of the "Burden of Therapy" (BOTh®TM) Methodology-A Novel Tool for Assessing Adverse Events in Metastatic Pancreatic Cancer.

This analysis of the RASH trial (NCT01729481) aimed at gaining a better understanding of the "Burden of Therapy" (BOTh®TM) in pancreatic ductal adenocarcinoma (PDAC). In the RASH study, 150 patients with newly diagnosed metastatic PDAC were treated with gemcitabine plus erlotinib (gem/erlotinib) for four weeks. Patients who developed a skin rash during this four-week run-in phase continued with the gem/erlotinib treatment, while rash-negative patients were switched to FOLFIRINOX. The study demonstrated a 1-year survival rate of rash-positive patients who received gem/erlotinib as first-line treatment that was comparable to previous reports of patients receiving FOLFIRINOX. To understand whether these comparable survival rates may be accompanied by better tolerability of the gem/erlotinib treatment compared to FOLFIRINOX, the BOTh®TM methodology was used to continuously quantify and depict the burden of therapy generated by treatment emergent events (TEAEs). Sensory neuropathy was significantly more common in the FOLFIRINOX arm, and prevalence as well as severity increased over time. In both arms, the BOTh®TM associated with diarrhea decreased over the course of treatment. The BOTh®TM caused by neutropenia was comparable in both arms but decreased in the FOLFIRINOX arm over time, possibly due to chemotherapy dose reductions. Overall, gem/erlotinib was associated with a slightly higher overall BOTh®TM, but the difference was not statistically significant (p = 0.6735). In summary, the BOTh®TM analysis facilitates the evaluation of TEAEs. In patients fit for intense chemotherapeutic regimens, FOLFIRINOX is associated with a lower BOTh®TM than gem/erlotinib.
