Risk Factors For Poor Overall Survival Research Articles

Prognostic impact of the high-sensitivity modified glasgow prognostic score on patients undergoing radical surgery for hepatocellular carcinoma : Authorship.

Our study aimed to assess the ability of high-sensitivity modified Glasgow prognostic Score (HS-mGPS) predicting survival in patients undergoing radical surgery for hepatocellular carcinoma (HCC) and to compare the impact with other Inflammation-Based prognostic scoring systems including Glasgow prognostic Score (GPS) and modified GPS (mGPS). Our study evaluated 293 patients with HCC who had undergone hepatectomy at the Third Affiliated Hospital of Soochow University between 2010 and 2018. The HS-mGPS, mGPS, and GPS were calculated based on particular cut-off values of preoperative C-reactive protein and albumin, and the correlations between HS-mGPS and clinicopathological parameters were evaluated. Univariate and multivariate survival analyses were conducted by Kaplan-Meier method and Cox proportional hazards model. To evaluate the discrimination ability of each prognostic score, the receiver operating characteristic (ROC) curve were generated and the areas under the curve (AUC) were measured and compared. The study results indicated a correlation between elevated HS-mGPS scores and adverse clinical factors, including higher BCLC stage, C-P grade, multiple tumors, and larger tumor diameter. Kaplan-Meier and univariate survival analyses revealed that higher scores of HS-mGPS, GPS, and mGPS were all associated with significantly reduced overall survival (OS) (all p < 0.001). In multivariate survival analysis, HS-mGPS emerged as an independent risk factor for poor OS in patients undergoing hepatectomy for HCC (p = 0.010), along with factors including maximal tumor diameter (p < 0.001), microvascular invasion (MVI) (p = 0.008), and BCLC stage (p = 0.001). The analysis of ROC curves and the AUC values indicated that HS-mGPS outperforms GPS and mGPS in predicting the long-term prognosis of patients with resectable HCC. Preoperative HS-mGPS proves superior in predicting adverse long-term outcomes in HCC patients undergoing radical surgery.

Impact of low sodium values on survival outcomes of patients with cancer receiving immune checkpoint inhibitors.

Background: Low serum sodium affects cancer prognosis, but its impact on immunotherapy is unclear. Objective: Assessing the association of pre- and post-ICI treatment sodium levels with survival. Methods: We retrospectively analyzed patients receiving ICI in January 2012-December 2023, collecting serum sodium levels at treatment initiation and 4weeks post-ICI, with overall survival (OS) as the primary outcome. Results: Low sodium was observed in 125 and 119 patients pre-and post-treatment respectively. Pre-ICI and post-ICI low sodium correlated with decreased OS [10.6 vs. 22.9months (p =0.001) and 11.6 vs. 27.2months (p =0.009)]. Multivariate analysis identified pre-ICI low sodium [HR: 1.685; 95% CI: 1.050-2.705; p =0.031] as an independent risk factor for worse OS. Conclusion: Low baseline serum sodium was an independent risk factor for poor OS in patients treated with ICIs.

Preoperative systemic inflammation response index enhances the prognostic value of tumor multifocalityin upper tract urothelial carcinoma.

In cancer, tumor-related inflammation affects disease progression and survival outcomes. However, the role of systemic inflammation in tumor multifocality in upper tract urothelial carcinoma (UTUC) is not well understood. The aim of the present study was to evaluate the impact of the systemic inflammation response index (SIRI) on tumor multifocality for predicting oncological outcomes in patients with UTUC after radical nephroureterectomy (RNU). For this purpose, data from 645 patients with non-metastatic UTUC who underwent RNU between 2008 and 2020 were retrospectively analyzed. Survival outcomes such as overall survival (OS), cancer-specific survival (CSS) and recurrence-free survival (RFS) RATES were assessed using the Kaplan-Meier method, and independent prognostic factors were identified through a multivariable Cox proportional hazards regression model. Of the 645 patients with UTUC included in the present study, 163 (25%) had multifocal UTUC. Kaplan-Meier analysis indicated that multifocal UTUC synchronous with a high-level SIRI was significantly associated with poorer outcomes after RNU. Furthermore, the results of the multivariate Cox proportional hazards model analysis demonstrated that multifocal tumor coupled with a high-level SIRI was an independent factor for predicting a shorter survival and disease progression. In conclusion, the results of the present study indicated that an elevated SIRI significantly influenced the survival rate of patients with multifocal UTUC. Specifically, integrating multifocal UTUC with a high-level SIRI emerged as an independent risk factor for poorer OS, CSS and RFS. These findings highlighted the potential role of SIRI in the risk stratification and management of patients with multifocal UTUC.

Midterm survival after aortic repair versus conservative treatment in patients with penetrating aortic ulcer.

Background: The clinical outcomes and survival of patients with penetrating aortic ulcers (PAU) were evaluated in a tertiary care hospital, comparing those who underwent aortic repair to those treated conservatively. Patients and methods: A retrospective single-centre analysis included all patients that underwent a computed tomography angiography (CT-A) scan with the diagnosis of a PAU between January 2009 and May 2019. "PAU" was identified in 1,493 of 112,506 CT-A scan reports in 576 patients. Clinical and angiomorphological data were collected. The primary outcome was overall survival (OS), with secondary outcomes focusing on identifying risk factors for poor OS. Survival probabilities were analysed by the Kaplan-Meier method using the log-rank test. A Cox hazard model using survival as dependent variable with stepwise backward eliminations based on the likelihood ratios was employed. Results: 315 PAUs were identified in 278 patients. The prevalence in the cohort was 0.8%. The mean age of the patients was 74.4 years, and they were predominantly male (n = 208, 74.8%). The mean ulcer depth was 11.8 mm (range 2-50 mm). Out of the patients, 232 were asymptomatic (83.5%). Among 178 PAUs (56.5%), high-risk factors, such as ulcer depth >10 mm, aortic diameter >40 mm, and ulcer length >20 mm, were observed. Aortic repair was associated with a better mean OS compared to conservatively managed patients (72.6 versus 32.2 months, p = 0.001). The Cox hazard model showed that ulcer depth >1 mm was associated with poor OS (HR 0.67, p = 0.048), while aortic repair was related to a better OS (HR 4.365, p<0.013). Conclusions: Aortic repair is associated with better OS, but this finding should be interpreted with caution because of differences in age and comorbidities between the groups. Further evaluation is warranted through prospective studies with randomized groups. Further assessment for angiomorphological parameters is recommended to identify patients at increased risk for poor OS.

Prognostic factors in pulmonary metastases resection from colorectal cancer: impact of right-sided colon cancer and early recurrence.

This retrospective cohort study aimed to explore the surgical outcomes and prognostic factors of resection of pulmonary metastases (PM) from colorectal cancer (CRC). Overall, 60 patients who underwent resection of PM from CRC between 2015 and 2021 at two institutions were reviewed. The primary outcome were overall survival (OS) and early recurrence after PM resection. The association between OS and right-sided colon cancer (RCC) was investigated. Early recurrence after PM resection was defined as recurrence within one year. The 5-year OS after CRC resection was 83.8% (95% confidence interval [CI] 67.5-92.4) and after PM resection was 69.4% (95% CI 47.5-83.6). In total, 25 patients had recurrence after PM resection (16 within 1year and 9 after 1year). In multivariable analysis for OS, RCC (hazard ratio [HR] 4.370, 95% CI 1.020-18.73; p = 0.047) and early recurrence after resection of PM (HR 17.23, 95% CI 2.685-110.6; p = 0.003) were risk factors for poor OS. In multivariable analysis for early recurrence after PM resection, higher value of carcinoembryonic antigen (CEA) (> 5.0mg/dL) before PM resection was a risk factor for early recurrence (HR 3.275, 95% CI 1.092-9.821; p = 0.034). The RCC and early recurrence after PM resection were poor prognosis factors of OS. Higher value of CEA before PM resection was an independent risk factor for early recurrence after resection of PM. Comparitive study between surgery and nonsurgery is necessary in patients with higher CEA values.

Long-term surgical outcomes of bile duct tumor thrombus versus portal vein tumor thrombus for hepatocellular carcinoma: a propensity score matching analysis.

Portal vein tumor thrombus (PVTT) seriously affects the prognosis of hepatocellular carcinoma (HCC). However, whether bile duct tumor thrombus (BDTT) significantly affects the prognosis of HCC as much as PVTT remains unclear. We aimed to compare the long-term surgical outcomes of HCC with macroscopic PVTT (macro-PVTT) and macroscopic BDTT (macro-BDTT). The data of HCC patients with macro-BDTT or macro-PVTT who underwent hemihepatectomy were retrospectively reviewed. A propensity score matching (PSM) analysis was performed to reduce the baseline imbalance. The recurrence-free survival (RFS) and overall survival (OS) rates were compared between the cohorts. Before PSM, the PVTT group had worse RFS and OS rates than the BDTT group (P = 0.043 and P = 0.008, respectively). Multivariate analyses identified PVTT (hazard ratio [HR] = 1.835, P = 0.016) and large HCC (HR = 1.553, P = 0.039) as independent risk factors for poor OS and RFS, respectively. After PSM, the PVTT group had worse RFS and OS rates than the BDTT group (P = 0.037 and P = 0.004, respectively). The 3- and 5-year OS rates were significantly higher in the BDTT group (59.5% and 52.1%, respectively) than in the PVTT group (33.3% and 20.2%, respectively). Aggressive hemihepatectomy provides an acceptable prognosis for HCC patients with macro-BDTT. Furthermore, the long-term surgical outcomes of HCC patients with macro-BDTT were significantly better than those of HCC patients with macro-PVTT.

Effect of Abdominal Aortic Calcification on Recurrence Following Initial Hepatectomy for Colorectal Liver Metastases.

The aim of the study was to analyze the association between abdominal aortic calcification (AAC) and patient prognosis following resection of colorectal liver metastases (CRLM). AAC potentially reflects intrahepatic immunity and is involved in tumor development and progression. However, the clinical effects of AAC on colorectal cancer (CRC) prognosis after curative-intent liver resection for CRLM remain unclear. We evaluated the effect of AAC on the clinical prognosis and metastatic patterns in 99 patients who underwent hepatectomy for CRLM between 2010 and 2019. The high-AAC group had significantly worse overall survival (OS) and remnant liver recurrence rate (RR) after propensity score matching to adjust for differences in baseline characteristics of patients and tumors. In multivariate Cox regression analyses, high AAC volume was an independent risk factor for poor OS and liver RR, but not poor lung RR. The expression of tumor necrosis factor-related apoptosis-inducing ligand, known as an anti-tumor marker, in liver natural killer (NK) cells was lower in the high-AAC group than in the low-AAC group. High AAC volume showed a strong relationship with remnant liver RR after curative resection of CRLM. High AAC volume may be responsible for the suppression of anti-tumor activity of liver NK cells, which results in an increased risk of liver recurrence and poor prognosis.

Preoperative Systemic Inflammation Score Predicts the Prognosis of Patients with Upper Tract Urothelial Carcinoma Undergoing Radical Nephroureterectomy

Background: To investigate the prognostic significance of systemic inflammation score (SIS) in upper tract urothelial carcinoma (UTUC) in patients undergoing radical nephroureterectomy (RNU). Methods: A total of 313 UTUC patients who underwent RNU at West China Hospital from May 2014 to June 2019 were retrospectively analyzed. The predictive value of SIS for relevant endpoints, including overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS), was assessed by Kaplan–Meier curves and the Cox proportional hazards model. Results: According to inclusion and exclusion criteria, 218 UTUC patients were ultimately included in this cohort study. Statistical analysis shows that increased SIS was significantly associated with higher TNM stage (p = 0.017), lower BMI (p = 0.037), absence of hemoglobin (p &lt; 0.001), and pathologic necrosis (p = 0.007). Kaplan–Meier survival curves clearly visually stratified survival for the three outcomes. After adjusting for tumor grade, the multivariate Cox proportional hazards model results showed that SIS was an independent risk factor for poor OS and CSS (HR = 1.89, 95% CI: 1.11–3.21, p = 0.0183, HR = 1.89, 95% CI: 1.07–3.33, p = 0.0285) in the advanced group. Conclusions: SIS was an independent risk factor for OS and CSS after RNU in patients with high-grade UTUC. It may be a novel and conducive tool for preoperative risk stratification and guiding individualized therapy for high-risk UTUC patients.

Recurrent metastatic patterns and prognosis after radical surgery in patients with alpha-fetoprotein-producing gastric cancer: a retrospective cohort study.

Alpha-fetoprotein-producing gastric cancer (AFPGC) is a rare and aggressive subtype of gastric cancer associated with poor prognosis. This study aimed to investigate the recurrent metastatic patterns and prognostic factors in AFPGC patients undergoing radical surgical resection. Data from 241 AFPGC patients diagnosed between January 2017 and January 2020 who underwent surgical resection were analyzed across multiple centers. Recurrence patterns, metastatic sites, and survival outcomes were evaluated. Univariate and multivariate analyses were performed to identify risk factors for recurrent metastasis, overall survival (OS), and disease-free survival (DFS). There is an annual increase in the proportion of AFPGC cases, rising from 3.45% in 2017 to 7.88% in 2023. Higher serum AFP level was associated with increased likelihood of lymph node metastasis (P=0.006), deeper invasion depth (P=0.000) and greater tumor diameter (P=0.036). Independent predictors of recurrent metastasis included T4 infiltration, lymph node metastasis, tumor diameter >5 cm, poorly differentiated-undifferentiated pathology, preoperative AFP>1000 ng/mL, and postoperative increasing trend in AFP levels. The 5-year OS and DFS rates were 36.5% and 34.2%, respectively, with poorer survival linked to higher preoperative AFP levels and postoperative increasing trend in AFP level. Independent risk factors for poor OS and DFS included T4 infiltration, lymph node metastasis, poorly differentiated-undifferentiated pathology, preoperative AFP>1000 ng/mL, and postoperative increasing trend in AFP. Serum AFP level can serve as a potential predictive and prognostic biomarker. Identifying independent risk factors informs risk stratification and personalized treatment for AFPGC patients.

The Co-Occurrence of bZIP in-Frame CEBPA-Mutation with Unfavorable Genetic Abnormalities Is Associated with a Poor Prognosis in Acute Myeloid Leukemia

In a previous study (SY Ahn et al, Cancer Res Treat 2023), we reported that the presence of only the basic leucine zipper in-frame mutation (bZIP in-f) CEBPA is associated with favorable outcomes in patients with CEBPAdouble mutations. However, when bZIP in-fCEBPAmutations were accompanied by certain mutations in chromatic/DNA modifiers, cohesion complex, and splicing genes, patients exhibited inferior overall survival (OS). FLT3-ITD or additional cytogenetic abnormalities is known to rarely co-occur with CEBPA mutation in patients with AML. In cases where both bZIP in-fCEBPA and FLT3-ITD coexist, there are conflicting aspects in risk stratification, and research on its prognostic significance is limited. Therefore, we aimed to evaluate the prognostic significances of the co-occurrence of bZIP in-fCEBPAmutation with unfavorable genetic abnormalities in acute myeloid leukemia. In 832 patients who were diagnosed with AML excluding acute promyelocytic leukemia and underwent intensive induction therapy, 98 (11.8%) had bZIP in-fCEBPA. Among 98 patients with bZIP in-fCEBPA, eight cases had FLT3-ITD (5 with low allelic ratio, 3 with high allelic ratio), 19 patients had unfavorable genetic mutations according to the 2022 European LeukemiaNet guidelines, and 10 patients had non-favorable cytogenetic abnormalities as detected in diagnostic samples. We observed no clinical differences in features such as age, sex, WBC count, bone marrow blast percentage at diagnosis based on the co-occurrence unfavorable genetic abnormalities (unfavorable-gene). Among the 98 patients with bZIP in-f CEBPA, 30 out of 37 patients with unfavorable-gene achieved complete remission (CR) after induction therapy, and 55 out of 61 without unfavorable genetic abnormalities showed CR (p=0.20). Allogeneic hematopoietic cell transplantation was proceeded at first CR in 21 out of 37 unfavorable-gene group, and 35 out of 61 bZIP in-fCEBPAonly group ( p=1.00). In the survival analysis, patients with FLT3-ITD, unfavorable genetic co-mutated, or non-favorable cytogenetic abnormalities with bZIP in-fCEBPA showed inferior OS (p=0.036) (Fig. A). Due to the limited number of patients for analysis, we classified them into two group: the unfavourable-gene group and bZIP in-fCEBPAonly group. We observed that the unfavourable-gene group had a poor OS compared to the bZIP in-fCEBPAonly group (HR 2.71, 95 CI; 1.32-5.55, p=0.007) (Fig.B). On multivariate analysis, unfavorable-gene group was only poorrisk factor for OS. Despite the inclusion of a relatively small number of patients, our study demonstrates that when co-occurrence of bZIP in-fCEBPA withunfavourable genetic abnormalities, it results in a poor prognosis. To confirm its clinical significance, further validation with a larger patient population is necessary.

Increased plasma miR-370-3p expression in poor-outcome patients with pancreatic ductal adenocarcinoma

ObjectiveTo determine whether circulating microRNAs (miRNAs) can be used as prognostic biomarkers for pancreatic ductal adenocarcinoma (PDAC). MethodsPatients with PDAC (N = 120) who underwent surgical resection at Hiroshima University Hospital between November 2006 and January 2020 were enrolled in this study and grouped based on their overall survival (OS) into two groups: favorable prognosis group (F group; OS ≥ 18 months) and unfavorable prognosis group (U group; OS < 18 months). Blood plasma samples were collected prior to surgery. To identify candidate prognostic miRNAs, next-generation sequencing (NGS) analysis was used to evaluate the expression levels of miRNAs in seven of the plasma samples. Using quantitative real-time PCR (qRT-PCR), the expression levels of the selected miRNAs were determined in the remaining 113 patient plasma samples, and the relationship between miRNA expression and survival was statistically evaluated. ResultsNGS analysis and qRT-PCR revealed significantly upregulated plasma miR-370-3p expression in the U group compared to that in the F group (p = 0.028 and p = 0.005, respectively). Moreover, miR-370-3p expression and lymph node metastasis showed a statistically significant association (p = 0.028). In a multivariate analysis of OS and recurrence-free survival (RFS), the upregulation of miR-370-3p expression in plasma was identified as an independent risk factor for poor OS (HR2.13, p = 0.004) and RFS (HR1.84, p = 0.015). ConclusionsPlasma miR-370-3p expression upregulation correlates with poor prognosis in patients with PDAC.

Reduction quality in lateral view of X-ray and hypoalbuminemia are associated with postoperative mortality in elderly pertrochanteric fracture patients.

Pertrochanteric fracture is one of the most prevalent public health issues across the world for the elderly population. The purpose of this study was to investigate the association between surgical factors and postoperative mortality in patients with intramedullary nail-treated pertrochanteric fractures. A retrospective cohort study was designed to evaluate the pertrochanteric fracture patients treated with intramedullary nail between January 2016 to February 2021. The surgical factors included the Dorr morphology, Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association (AO/OTA) classification of fractures, the tip-apex distance (TAD), location of the cephalic screw, reduction quality in anterior-posterior (AP) and lateral views, the integrity of the lateral wall, and the design of cephalic screws. Using univariate and multivariate Cox proportional hazard models, the association between these risk factors and postoperative mortality in patients with this type of fractures was evaluated. A total of 169 pertrochanteric fracture patients treated with intramedullary nails were included in our study, with the average age of 82.68±5.93 years. The mortality rates at 3 months, 1 year, and the end of follow-up were 4.14%, 11.24%, and 26.04%, respectively. According to the univariate Cox analysis, age, gender, preoperative levels of hemoglobin (Hb) and albumin (Alb) were associated with a poor overall survival (OS) (P<0.05). After multivariate adjustment, the pre-operative level of Alb (P<0.001) and the reduction in lateral view (P<0.001) were shown to be independent risk factors for poor OS. The preoperative hypoalbuminemia and reduction quality in lateral view were associated with postoperative mortality in our study. Therefore, optimizing both parameters could improve the prognosis in elderly pertrochanteric fracture patients.

41. HIGH COMPREHENSIVE COMPLICATION INDEX AFTER MINIMALLY INVASIVE ESOPHAGECTOMY ASSOCIATED WITH POOR SHORT-TERM AND LONG-TERM OUTCOME: A PROPENSITY SCORE MATCHING ANALYSIS

Abstract Introduction The comprehensive complication index (CCI) is a new index to comprehensively and systematically evaluate complication severity. The objective of this study was to evaluate the predictive ability of CCI on short—and long-term overall survival(OS) in patients with esophageal squamous cell carcinoma (ESCC) undergoing minimally invasive esophagectomy (MIE) based on a propensity Score Matching (PSM) analysis. Methods A total of 356 patients treated with radical MIE from 2013 to 2017 were included, and the primary outcome was OS, and the secondary outcomes were postoperative hospital stay and hospital costs. Firstly, the optimla cut-off value of CCI was determined by X-tile. PSM was used to balance the baseline characteristics. Second, we compared postoperative hospital stay and hospital costs between high- and low-CCI group. Third, the Kaplan–Meier survival curve was used to analyze survival difference. Fourth, univariate and multivariate Cox analysis was used to explore the independent risk factors of OS. Results The CCI &amp;gt; 24.2 was defined as high-CCI group and CCI≦24.2 was defined as low-CCI group. The high-CCI group had more hospital costs and longer hospital stay than the low-CCI group both before and after PSM (p &amp;lt; 0.001). The K-M analysis indicated that patients with high CCI had worse prognosis both before and after PSM (before matching: P &amp;lt; 0.001; after matching: P = 0.04). CCI was determined as independent prognostic factor both before and after PSM (before PSM, P = 0.002; after PSM, P = 0.025). Conclusion The CCI could quantify postoperative complications after esophagectomy. High CCI is associated with longer hospital stay and hospitalization costs, and is an independent risk factor for poor OS.

PARP10 is highly expressed and associated with inferior outcomes in acute myeloid leukemia.

Acute myeloid leukemia is a heterogeneous disease of the hematopoietic system, which possesses a poor prognosis; thus, the identification of novel molecular markers is urgently needed to better define the risk stratification and optimize treatment therapies for this disease. Here, we investigated the roles of the PARP family genes in AML by analyzing their mRNA expression profiles and their association with clinical features using data from TCGA and GSE. Our results showed that PARP10 was significantly more highly expressed in AML samples than in normal controls, and high expression of PARP10 was associated with older age (≥60 years, P = 0.012), more frequent TP53 mutations (P = 0.024), high-risk stratification (P < 0.05), and poorer outcomes (P < 0.05). Patients with high expression of PARP10 exhibited significantly poorer overall survival (OS) and event-free survival (EFS) than those with low PARP10 expressions (OS: median: 0.88 vs. 2.19 years; P = 0.001; EFS: median: 0.65 vs. 1.12 years; P = 0.041). Multivariate analysis indicated that high expression of PARP10 was an independent risk factor for poorer OS and EFS in AML patients. Moreover, we found that allo-SCT improved OS for AML patients with high PARP10 expression but not for patients with low PARP10 expression, while allo-SCT decreased EFS for patients with low PARP10 expression. Finally, we confirmed that PARP10 knockout impaired AML cell proliferation in vitro. In summary, our data suggested that PARP10 is aberrantly expressed in AML, and high expression of PARP10 might be a biomarker for poor prognosis and also a potential indicator for allo-SCT therapy, which might provide precise treatment indications for physicians.

Surgical Treatment Outcomes of Patients with Non-Small Cell Lung Cancer and Lymph Node Metastases

This study aimed to investigate the appropriate subgroups for surgery and adjuvant chemotherapy in patients with non-small-cell lung cancer (NSCLC) and nodal metastases. We retrospectively reviewed 210 patients with NSCLC and nodal metastases who underwent surgery and examined the risk factors for poor overall survival (OS) and recurrence-free probability (RFP) using multivariate Cox proportional hazards analysis. Pathological N1 and N2 were observed in 114 (52.4%) and 96 (47.6%) patients, respectively. A single positive node was identified in 102 patients (48.6%), and multiple nodes were identified in 108 (51.4%). Multivariate analysis revealed that vital capacity &lt; 80% (hazard ratio [HR]: 2.678, 95% confidence interval [CI]: 1.483–4.837), radiological usual interstitial pneumonia pattern (HR: 2.321, 95% CI: 1.506–3.576), tumor size &gt; 4.0 cm (HR: 1.534, 95% CI: 1.035–2.133), and multiple-node metastases (HR: 2.283, 95% CI: 1.517–3.955) were significant independent risk factors for poor OS. Tumor size &gt; 4.0 cm (HR: 1.780, 95% CI: 1.237–2.562), lymphatic permeation (HR: 1.525, 95% CI: 1.053–2.207), and multiple lymph node metastases (HR: 2.858, 95% CI: 1.933–4.226) were significant independent risk factors for recurrence. In patients with squamous cell carcinoma (n = 93), there were no significant differences in OS or RFP between those who received platinum-based adjuvant chemotherapy (n = 25) and those who did not (n = 68), at p = 0.690 and p = 0.292, respectively. Multiple-node metastases were independent predictors of poor OS and recurrence. Patients with NSCLC and single-node metastases should be considered for surgery despite N2 disease. Additional treatment with platinum-based adjuvant chemotherapy may be expected, especially in patients with squamous cell carcinoma.

Does Pathological T-Factor Affect Long-term Prognosis of Locally Advanced Colorectal Cancer Treated With Laparoscopic Multivisceral Resection?

Locally advanced colorectal cancer (LACC) has poor long-term outcomes. Our hypothesis was that the pathological tumor depth would affect postoperative outcomes in patients who underwent multivisceral resection with clear margins (R0). The aim of this study was to analyze short- and long-term outcomes in patients who underwent multivisceral resection for LACC, comparing between T3 and T4 stages. This was a propensity score-matched, retrospective study. All 8,764 consecutive patients who underwent surgery for colorectal cancer between April 2007 and January 2021 at the Saitama Medical University International Medical Center were screened; 572 underwent multivisceral resection for LACC. We compared the T3 and T4 groups to evaluate outcomes. The 5-year disease-free survival (DFS) rates did not significantly differ between the two groups (hazard ratio=1.344, 95% confidence interval=0.638-2.907, p=0.33). The 5-year overall survival (OS) rates were significantly worse for the T4 group than for the T3 group (hazard ratio=3.162, 95% confidence interval=1.077-11.44), p=0.037). To determine the association between American Society of Anesthesiologists (ASA) score, transfusion, pathological T and OS, we performed univariate and multivariate analyses. ASA, transfusion, and pathological T-stage were associated with worse OS in univariate analysis (T4 vs. T3, respectively). Our study showed that postoperative complications and DFS of the T4 group were similar to those of the T3 group of locally advanced colorectal cancer treated with laparoscopic multivisceral resection. However, OS was worse in the T4 group compared with the T3 group. Multivariate risk factors for poor OS were ASA>2, transfusion, and T4 stage.

Effect of abdominal aortic calcification on the prognosis and recurrence of colorectal cancer stages II–III: A retrospective cohort study

Abdominal aortic calcification (AAC) is a well-known risk marker for cardiovascular disease. However, its clinical effect on patients who underwent radical surgery for colorectal cancer (CRC) stages II-III is unclear. This study aimed to analyze the associations between AAC and prognosis of patients with stage II-III CRC. To evaluate the effect of AAC on clinical outcomes, prognosis, and metastatic patterns of CRC, we analyzed 362 patients who underwent radical surgery for stage II-III CRC between 2010 and 2018. The high AAC group had significantly worse overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) after propensity score matching to adjust for differences in baseline characteristics of patients and tumors. In the multivariate Cox regression analyses, a high AAC was an independent risk factor for poor OS (hazard ratio [HR], 2.38; 95% confidence interval [CI], 1.23-4.59; p = 0.01), poor CSS (HR, 5.22; 95% CI, 1.74-15.6; p < 0.01), and poor RFS (HR, 1.83; 95% CI, 1.19-2.83; p < 0.01). A high AAC was not associated with a risk of lung metastasis or local or peritoneal recurrence, but a risk for liver metastasis of CRC. A high AAC showed a strong relationship with poor OS, CSS, and RFS after curative resection for stage II-III CRC. A high AAC was also associated with a risk for liver metastasis, which may worsen the prognosis in stage II-III CRC. AAC could be a new clinical tool for predicting the prognosis for patients in stage II-III CRC.

Perineural invasion predicts poor survival and cervical lymph node metastasis in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) usually invades peripheral nerves through a process known as perineural invasion (PNI), recognized as an adverse factor considered for the administration of postoperative adjuvant therapy. The aim of this study was to assess the impact of PNI on survival and cervical lymph node metastasis in a cohort of OSCC patients. Presence, location and extension of PNI were assessed in a cohort of 57 paraffin-embedded OSCC resections. Clinico-pathological variables were obtained from each case. Five-year overall survival (OS) and 5-year disease-specific survival (DSS) curves were constructed according to the Kaplan-Meier method and compared with log-rank test. The Cox proportional hazard model was used to assess the role of PNI as an independent risk factor related to poor survival, and a binary logistic regression was performed to estimate the predictive value of PNI for regional lymph node metastasis. PNI was observed in 49.1% of the cases, affecting only small nerves. Peritumoral PNI was the most common location, and multifocal PNI the most frequent extent. Most PNI positive cases had cervical metastasis (p=0.001), and PNI was more frequent in stages III-IV than in I-II (p=0.02). The five-year OS and the 5-year DSS decreased in PNI positive and peritumoral PNI cases. PNI was an independent risk factor for poor 5-year OS and poor 5-year DSS. The odds for cervical lymph node metastasis were of 6.076 (p=0.006) and 10.257 (p=0.007) for PNI and Tumor budding (TB) positive cases, respectively. PNI is a frequent finding in OSCC and an independent risk factor for poor OS and DSS. PNI and TB are both risk factors associated to an increased likelihood for the development of lymph node metastasis. Therefore, we suggest further investigations to test the combined PNI-TB scoring system in risk stratification models for OSCC.

Prognostic outcomes of cytomegalovirus reactivation after autologous stem cell transplantation.

Background: Cytomegalovirus (CMV) reactivation is a common complication in patients undergoing allogeneic stem cell transplantation. However, the incidence of CMV reactivation is low after autologous stem cell transplantation (auto-SCT), and the prognostic value of CMV reactivation remains controversial. Moreover, reports on late CMV reactivation after auto-SCT are limited. We aimed to analyze the association between CMV reactivation and survival outcomes and develop a predictive model for late CMV reactivation in patients undergoing auto-SCT. Methods: Data of 201 patients who underwent SCT at the Korea University Medical Center from 2007 to 2018 were collected. We analyzed prognostic factors for survival outcomes after auto-SCT and risk factors for late CMV reactivation using a receiver operating characteristic curve. Then, we developed a predictive risk model for late CMV reactivation based on results of the risk factor analysis. Results: Early CMV reactivation was significantly associated with better overall survival (OS) (hazard ratio [HR], 0.329; P = 0.045) in patients with multiple myeloma; however, no significant differences were observed in patients with lymphoma. For late CMV reactivation, a serum lactate dehydrogenase level greater than the upper limit of normal (HR, 2.251; P = 0.027) and late CMV reactivation (HR, 2.964; P = 0.047) were independent risk factors for poor OS, while lymphoma diagnosis (vs. multiple myeloma; HR, 0.389; P = 0.016) was an independent risk factor for good OS. In risk factor analysis for late CMV reactivation, T-cell lymphoma diagnosis (odds ratio [OR], 8.499; P = 0.029), ≥ two prior chemotherapies (OR, 8.995; P = 0.027), failure to achieve complete response (CR) after transplantation (OR, 7.124; P = 0.031), and early CMV reactivation (OR, 12.853; P = 0.007) were significantly associated with late CMV reactivation. To develop the predictive risk model for late CMV reactivation, a score (1 to 1.5) was assigned for each of the above-mentioned variables. The optimal cutoff value (1.75 points) was calculated using the receiver operating characteristic curve. The predictive risk model showed good discrimination, with an area under the curve of 0.872 (standard error, 0.062; P < 0.001). Conclusions: Late CMV reactivation was an independent risk factor for inferior OS, whereas early CMV reactivation was associated with better survival in patients with multiple myeloma. This risk prediction model could be helpful in identifying high-risk patients who require monitoring for late CMV reactivation and potentially benefit from prophylactic or preemptive therapy.

Impact of metabolic syndrome on the long-term prognosis of patients with hepatitis B virus-related hepatocellular carcinoma after hepatectomy.

The long-term prognosis of patients with metabolic syndrome (MS) and hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) after radical hepatectomy remains unclear. The purpose of this study was to elucidate the effect of MS on long-term survival for patients with HBV-related HCC after hepatectomy. Patients with HBV-HCC after hepatectomy were included. Patients were stratified into MS-HBV-HCC and HBV-HCC groups. Clinical features and surgical outcomes were compared between the two groups, and COX regression analysis was used to determine independent risk factors associated with overall survival (OS) and recurrence-free survival (RFS). 389 patients (MS-HBV-HCC group: n=50, HBV-HCC group: n=339) were enrolled for further analysis. Baseline characteristics showed that patients with MS-HBV-HCC were associated with a high rate of elderly patients, ASA score, and co-morbid illness, but a lower rate of anatomy hepatectomy. There were no significant differences in perioperative complications. After excluding patients who relapsed or died within 90 days after surgery, multivariate Cox regression analysis showed MS was an independent risk factor of OS (HR 1.68, 95% CI 1.05-2.70, P = 0.032) and RFS (HR 1.78, 95% CI 1.24-2.57, P = 0.002). MS is an independent risk factor for poor OS and RFS in HBV-infected HCC patients after radical hepatectomy. This suggests that we need to strengthen postoperative follow-up of the relevant population and encourage patients to develop a healthy lifestyle.
