Clinical significance of CD155 expression in surgically resected lung squamous cell carcinoma.

Cluster of differentiation 155 (CD155) is expressed in many tumor types. CD155 is involved in the immune avoidance of tumor cells and contributes to tumor development and progression. Therefore, CD155 is a novel target for cancer immunotherapy. The clinical significance of CD155 expression in lung squamous cell carcinoma (LUSC) has not been fully elucidated. We performed a retrospective analysis of 264 patients with surgically resected LUSC. Immunohistochemistry was used to evaluate CD155 expression. The association of CD155 expression with clinicopathological features and clinical outcomes was assessed. We also analyzed the relationship between CD155 expression and programmed cell death-ligand 1 (PD-L1) expression and tumor-infiltrating lymphocytes. Among the 264 patients, 137 patients (51.9%) were classified in the high CD155 expression group. High CD155 expression was significantly associated with pleural invasion, vascular invasion, PD-L1 positivity, and high CD3, CD4, and CD8 expressions. In multivariate analysis, the presence of pleural invasion and PD-L1 positivity were independent predictors of high CD155 expression. Kaplan-Meier curve analysis showed that high CD155 expression was significantly associated with shorter disease-free survival and overall survival. In multivariate analysis, high CD155 expression was an independent poor prognostic factor for overall survival, but not for disease-free survival. Subgroup analyses revealed that the prognostic effect of CD155 expression was observed in the PD-L1 positive group but not the PD-L1 negative group. Our analysis revealed that high CD155 expression significantly predicted poor prognosis in patients with surgically resected LUSC, especially in patients with PD-L1-positive tumors.

Impact of distant metastasis on overall survival and cancer specific survival of elderly patients with differentiated thyroid cancer

Distant metastases are common in most elderly patients, because elderly patients are diagnosed with advanced thyroid cancer due to delayed diagnosis. There is still few specific real-world data regarding prognosis in the elderly with differentiated thyroid cancer (DTC). The purpose of this study is to evaluate the prognostic factors and survival rate of elderly DTC patients with metastasis. This retrospective study included 14,603 elderly patients diagnosed with DTC from 2010 to 2015, including 447 patients with distant metastasis via the Surveillance, Epidemiology and End Results (SEER) database. The prognostic factors of overall survival (OS) and cancer-specific survival (CSS) in elderly DTC patients with metastasis or non-metastasis were determined by univariate and multivariate analysis. Age, primary site operation, radiotherapy, chemotherapy and tumor size are associated with OS and CSS in elderly DTC patients with distant metastasis. Compared with the patients without surgery, patients with total thyroidectomy showed significantly better OS. For the elderly DTC patients, radiotherapy was associated with improving OS and CSS. Chemotherapy increased the risk of death. For elderly DTC patients, early identification of distant metastasis, total thyroidectomy and radiotherapy are associated with better prognosis.

Evaluation of a targeted anti-αvβ3 integrin near-infrared fluorescent dye for fluorescence-guided resection of naturally occurring soft tissue sarcomas in dogs.

Complete resection is a key prognostic factor for survival in patients with soft tissue sarcoma (STS), in humas and companion animals alike. Fluorescence-guided surgery could improve resection accuracy. As dogs are frequently affected by STS, they serve as a model to test an anti-αvβ3 integrin targeting near-infrared fluorescent (NIRF) dye (AngiostampTM800) for fluorescence-guided surgery in STS to evaluate its safety and feasibility in dogs, and if it translates into a clinically relevant benefit compared to the standard of care with regards to completeness of surgery and local recurrence. Furthermore, we aimed to correlate target expression and NIRF-signal intensity. Twenty dogs with STS were randomly allocated to either receive Angiostamp™ (NIRF group) or physiologic saline (control group) preoperatively. The researchers were blinded for treatment, and resections were adapted based on the NIRF-signal, if needed. Margin status was histologically determined at the 1 and 3cm margin. The tumor-to-background ratio was measured in native tissue biopsies and formalin-fixed tissue. The fluorescent area was compared to the corresponding tumor areas as confirmed by histology using the Dice coefficient. Target expression was quantified by immunohistochemistry and correlated to NIRF-signal ratios. A fluorescent signal was detected in all 10 tumors of the NIRF group, with a tumor-to-background ratioof 7.4 ± 5.8 in native biopsies and 13.5 ± 10.9 in formalin-fixed tissue. In the NIRF group, resection margins were adapted in 5/10 cases, leading to complete resection and preventing R1 in four of these cases. In the NIRF and control group 9/10 and 8/10 resections were R0, with one local recurrence in each group and one sarcoma-related death in the NIRF group. The NIRF-signal correlated with the histologically confirmed tumor area (Dice coefficient 0.75 ± 0.17). Target expression was higher in tumor compared to peritumoral tissue (p < 0.0003) and showed a moderate correlation with the NIRF-signal (r = 0.6516, p < 0.0001). Fluorescence-guided surgery using Angiostamp™ can pinpoint residual disease in the tumor bed and contributes to an improved resection accuracy in canine STS.

Identification and Validation of the Hsa_circ_0001726/miR-140-3p/KRAS Axis in Hepatocellular Carcinoma Based on Microarray Analyses and Experiments.

Hepatocellular carcinoma (HCC) is one of the most fatal malignancies. Epigenetic mechanisms have revealed that noncoding RNAs, such as microRNAs (miRNAs) and circular RNAs (circRNAs), are involved in HCC progression. This study aimed to construct a circRNA-miRNA-mRNA network in HCC and validate one axis within the network. HCC-related transcriptome data were obtained from the Gene Expression Omnibus, and HCC-related genes were sourced from GeneCards to identify differentially expressed circRNAs and miRNAs. The targeting relationships between circRNA-miRNA and miRNA-mRNA interactions were predicted. The involvement of the hsa_circ_0001726/miR-140-3p/KRAS axis in HCC was evaluated through cellular experiments and survival analyses. We identified six differentially expressed circRNAs in HCC, which were linked to 13 miRNAs and 88 mRNAs. A network containing 34 circRNA-miRNA pairs and 194 miRNA-mRNA pairs was constructed. Cell proliferation and migration assays confirmed the role of hsa_circ_0001726 in promoting HCC progression, possibly through the miR-140-3p/KRAS axis. Survival analysis verified that hsa_circ_0001726 was a prognostic factor for overall survival in patients with HCC. The hsa_circ_0001726/miR-140-3p/KRAS axis also mediates lenvatinib resistance in HCC cells. The HCC circRNA/miRNA/mRNA network provides new insights into the post-transcriptional regulatory mechanism of HCC. The hsa_circ_0001726/miR-140-3p/KRAS axis is involved in HCC progression and lenvatinib resistance.

Neoadjuvant Treatment with Changes in Chemotherapy Regimens According to Carbohydrate Antigen 19-9 Level for Resectable/Borderline Resectable Pancreatic Ductal Adenocarcinoma.

The response of carbohydrate antigen (CA) 19-9 to neoadjuvant therapy (NAT) for pancreatic ductal adenocarcinoma (PDAC) may contribute to outcomes. This study aimed to investigate the effect of changes in NAT regimens based on CA19-9 level. This single-center retrospective study included patients with resectable/borderline resectable (R/BR)-PDAC undergoing NAT from 2008 to 2022. A CA19-9 level lower than 150 IU/mL after NAT was the criterion for resection. If the level did not decrease, the chemotherapy regimen was changed to satisfy the criterion. The patient cohort was divided into group A (satisfied criterion without changing chemotherapy), group B (did not receive chemotherapy change, could not satisfy the criterion), group C (received chemotherapy change, satisfied the criterion), and group D (received chemotherapy change, could not satisfy the criterion). The study cohort included 283 patients. After first-line chemotherapy, 112 (39.6%) patients did not satisfy the criterion (groups B [n = 64], C [n = 32], and D [n = 16]). Of the 283 patients, 48 (17%) received a chemotherapy change (groups C and D). The patients in groups C and D showed significantly better overall survival (OS, 35.9 months) than the group B patients (25.7 months) (P = 0.035). The OS of the group C patients (63.8 months) was similar to the OS of the group A patients (n = 171: 56.3 months; P = 0.430). Multivariate analysis of the patients in groups B, C, and D identified chemotherapy change as an independent prognostic factor for OS and progression-free survival. Changing the chemotherapy targeting the CA19-9 level can improve the outcome of R/BR-PDAC patients with poor biologic response to first-line NAT.

Lung cancer survival trends and prognostic factors: A 26-year population-based study in Girona Province, Spain

BackgroundLung cancer (LC) is Europe’s primary cause of cancer-related mortality largely due to its historically low survival rates. The aim of this study was to analyze 26-year survival trends in the province of Girona, Spain, and to identify key prognostic factors. MethodsPopulation-based study of LC cases collected between 1994 and 2019, with follow-up until December 31, 2021. Variables included date of diagnosis, sex, age, histology, and tumor stage (the latter since 2010). Diagnosis dates were categorized into three periods (1994–2002, 2003–2011, and 2012–2019). Multivariate flexible parametric models, incorporating age as a non-linear, time-varying covariate, were used to analyze net survival (NS) and trends. Annual absolute change in survival (AAC_S) was calculated using 3-year NS. ResultsThe analysis of 9,113 LC cases showed a NS improvement between the first and last period (7.1 months (95 %CI: 6.5;7.6) to 8.5 months (95 %CI: 7.9;9.1)). Squamous cell carcinoma (NSC-SCC) showed the greatest improvement with an AAC_S of 0.32 % (95 % CI: 0.21; 0.43), while survival for non-small cell lung cancer not otherwise specified declined (AAC_S of −0.19 % (95 %CI: −0.26; −0.12)). Prognostic analysis of the 3,642 cases (2010–2019) indicated a lower LC death risk for adenocarcinoma and NSC-SCC compared to LC not otherwise specified (HR 0.52 and 0.62, respectively). Increasing tumor stage correlated with higher LC mortality risk (1.8-, 4.0-, and 10.1-fold increase for stage II, III, and IV, respectively, compared to stage I). ConclusionsLC survival has notably improved, particularly for NSC-SCC. Survival is influenced by sex, age, date of diagnosis, tumor histology and especially by stage, underscoring comprehensive data collection’s importance.

Survival and Prognostic Factors After Surgery in Single Spinal Metastasis: Comparison of Isolated-Single Spinal Metastasis and Single Spinal Metastasis With Other Metastasis.

Retrospective cohort study. This study aimed to evaluate the survival period in patients with a single spinal metastasis (SSM), subsequently comparing those with isolated-single spinal metastasis (I-SSM) and single spinal metastasis with other metastasis (O-SSM) after surgery, and to identify prognostic factors affecting their survival. A total of 135 patients were included, with 24 patients in the I-SSM group and 111 in the O-SSM group. Survival analysis was utilized to assess the survival of SSM patients, followed by a comparison of survival rates between the two groups. Univariate and multivariate analyses were conducted to identify significant prognostic factors for survival. The overall median survival period for patients with single spinal metastasis (SSM) was 10.2 ± 1.8months. Specifically, the median survival was 15.7 ± 5.7months in the I-SSM group and 10.2 ± 1.5months in the O-SSM group. The difference in survival periods between the two groups was not statistically significant (P = 0.345). Significant independent prognostic factors for survival included preoperative Karnofsky Performance Status (KPS) of 50 - 70 (OR 0.51, P = 0.017) and 80 - 100 (OR 0.46, P = 0.012), postoperative ambulatory status (OR 1.19, P = 0.028), and primary malignancy site [Group B (OR 2.67, P = 0.021), Group C (OR 2.90, P = 0.016)]. Patients with SSM have a median survival of 10.2months, with no significant difference in postoperative survival between the I-SSM and O-SSM groups. Significant prognostic factors influencing the survival period after surgery include preoperative KPS, postoperative ambulatory status, and the primary malignancy site.

Incidence of myelosuppression in AML is higher compared with that in ALL.

Acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) are two subtypes of acute leukemia. However, studies investigating the ability of complete blood count (CBC) parameters to distinguish between patients with AML and ALL remain scarce in the literature. The objective of the present study was to compare the parameters of CBC analysis between Chinese patients with AML and ALL and between patients with M3 AML and non-M3 AML. Prognostic factors for overall survival were also estimated, including sex, age, white blood cell count and hemoglobin. The present study included 147 patients, including children and adults, with newly diagnosed acute leukemia. Information on the age, sex, leukemia subtype, initial CBC results and clinical follow-up findings was recorded and compared between the indicated groups using statistical tests of Mann-Whitney U test and χ2 test. Leukopenia (white blood cell count <3.5x109/l), both leukopenia and anemia, both leukopenia and thrombocytopenia and pancytopenia were found to be significantly more frequent among patients with AML compared with that in patients with ALL (P=0.015, 0.016, 0.015 and 0.019, respectively). For patients with ALL, anemia was recognized as a predictor of a favorable outcome (Hazard ratio, 0.185; 95% CI, 0.046-0.747; P=0.018). These findings suggest that normal hematopoiesis is more frequently inhibited in patients with AML compared with that in patients with ALL. Patients with AL with peripheral blood findings indicative of leukopenia, pancytopenia, or both leukopenia and anemia or both leukopenia and thrombocytopenia are more likely to have AML.

Prognostic significance of ER-to-PR difference in ER+/HER2- early breast cancer

ER+/HER2- breast cancer is a common subtype of breast cancer. This study aimed to evaluate the prognostic value of ER-to-PR difference (EPD) in ER+/HER2- early breast cancer (EBC). A retrospective cohort study was conducted, including 3,340 ER+/HER2- EBC patients, divided into a training cohort of 2,873 patients and a validation cohort of 467 patients. The optimal EPD cutoff value for stratifying patients was determined using X-tile. Additionally, the prognostic value of EPD, when combined with other clinicopathological factors, was assessed using the Cox proportional hazards model and five traditional machine learning methods. The optimal cutoff value for EPD was determined as 10%, categorizing patients into EPD-low (ER-PR ≤ 10%) and EPD-high (ER-PR > 10%) expression groups. Patients with EPD-high tumors exhibited a poorer prognosis compared to those with EPD-low tumors. In the multivariate Cox model, EPD was identified as an independent prognostic factor for disease-free survival (DFS) (HR: 1.496, P = 0.004). Integrating EPD with clinicopathological parameters into a predictive model effectively predicts DFS in ER+/HER2- EBC patients. In the most effective CoxPH model, the area under the curve (AUC) values for predicting 3-year, 5-year, and 7-year DFS were 0.718, 0.702, and 0.701, respectively, in the WCH cohort, and 0.770, 0.739, and 0.743, respectively, in the FUSCC cohort. EPD may serve as a novel prognostic marker, allowing for the identification of a population with a poor prognosis in ER+/HER2- EBC, thereby aiding clinical decision-making.

The relationship between the Prognostic Nutritional Index and lymphovascular and perineural invasion of the tumor in patients diagnosed with gastric cancer, and its effect on overall survival.

A low Prognostic Nutritional Index (PNI) value, lymphovascular invasion (LVI), and perineural invasion (PeNI) have been identified as indicators of poor prognosis for many malignancies. We aimed to evaluate the relationship between PNI and LVI/PeNI, their prognostic significance, and their effect on overall survival in gastric cancer patients who underwent curative gastrectomy. A cutoff value of 39.8 was taken for the PNI, and PNI < 39.8 was defined as moderate to severe malnutrition. Patients were grouped as PNI-low (PNI < 39.8) and PNI-high (PNI ≥ 39.8). Paraffin-embedded tissue sections of surgical specimens were used to evaluate PeNI as defined by previously reported criteria. The study included 270 patients with ages ranging from 23 to 90 years. The mean PNI was calculated as 39.8 ± 6.35. PeNI was detected in 232 patients (85.93%), and LVI was identified in 248 patients (91.85%). It was observed that the PNI value of patients with an expired status in the PNI < 39.8 group was lower compared to those who survived, and in patients with PNI > 39.8, those without PeNI had better survival. The presence of PeNI in patients with PNI > 39.8 increased the mortality risk by 2.088 units, while in patients with PNI > 39.8, it was found that those without LVI had better survival, and the presence of LVI increased the mortality risk by 3.171 units. Mortality developed in 166 patients (61.48%) during the five-year follow-up period. The five-year overall survival was found to be 31.02 ± 21.73 months. In patients with gastric cancer, the PNI, LVI, and PeNI are independent prognostic factors for overall survival in postoperative patients. A low PNI score is an inherently poor prognostic factor. In patients with a high PNI score, the presence of positive LVI and PeNI negatively impacts survival. We found that in patients with a low PNI, the rates of PeNI and LVI are higher compared to those with a high PNI, and this significantly affects mortality.

Evaluation of Ki-67 expression and large cell content as prognostic markers in MZL: a multicenter cohort study

Marginal zone lymphoma (MZL) can have varied presentations and pathologic features, including high Ki-67 expression ( > 20%) as well as increased numbers of large B cells (LC). However, there are limited data available demonstrating the prognostic significance of these variables in patients with MZL. In this multi-institutional retrospective cohort study of patients with MZL treated at 10 centers, we evaluated the association between the presence of Ki-67 expression and increased LCs on survival and risk of histologic transformation (HT). A total of 785 patients were included (60% with extranodal MZL, 20% with nodal MZL, and 20% with splenic MZL). Among the 440 patients with Ki-67 staining, 22% had high Ki-67 (Ki-67 >20%). The median progression-free survival (PFS) for patients with high Ki-67 was 5.4 years compared to 7.0 years for patients with low Ki-67 (HR = 1.45, 95%CI = 1.03–2.05). Ki-67 > 20% strongly correlated with high LDH level. The risk of HT was higher in patients with increased Ki-67 than those without (5-year risk, 9.8% vs 3.87%, p = 0.01). Twelve percent of patients had LC reported on biopsy with 6% having >10% LC. The presence of LC was associated with high Ki-67 (p < 0.001), but not associated with shorter PFS or overall survival (OS). The cumulative risk for HT was higher in patients with LC compared to those without LC (5-year risk, 9.4% vs 2.9%, p = 0.04). Receipt of anthracycline-based therapy did not impact PFS or OS in either group. Ki-67 staining >20% was a prognostic factor for worse survival and strongly correlated with elevated LDH. Novel therapies should be investigated for their potential ability to overcome the high-risk features in MZL. Our data reinforce the importance of obtaining biopsies at relapse or progression, particularly in patients with baseline high Ki-67 and increased LCs, given their increased risk for HT.

SH3 domain‑binding glutamic acid‑rich protein‑like 3 is associated with hyperglycemia and a poor outcome in Epstein‑Barr virus‑negative gastric carcinoma.

SH3 domain-binding glutamic acid-rich protein-like 3 (SH3BGRL3) is involved in several human cancers. However, its relationship with gastric cancer (GC) remains elusive. Multiple online bioinformatic tools were used to evaluate the messenger (m)RNA expression levels of SH3BGRL3 in GC using data from The Cancer Genome Atlas and Gene Expression Omnibus databases. Reverse transcription-quantitative PCR and tissue microarray-based immunohistochemistry were performed to assess SH3BGRL3 expression in relation to clinicopathological parameters and outcomes in patients with GC. Significant differentially expressed genes (DEGs) of SH3BGRL3 were enriched and visualized. Furthermore, associations between the expression of SH3BGRL3 and the infiltration of immune cells were explored. SH3BGRL3 exhibited aberrant expression in tumor tissues compared with adjacent normal tissues at the mRNA and protein expression levels, especially in Epstein-Barr virus-negative GC (EBVnGC). Higher SH3BGRL3 expression was significantly associated with increasing tumor-node-metastasis staging, tumor budding, perineural invasion, EGFR expression, and a notably higher preoperative blood glucose concentration in clinical specimens. Multivariate analysis revealed that higher SH3BGRL3 expression was an independent adverse prognostic factor for the overall survival of patients with EBVnGC (hazard ratio, 1.666; P=0.018). Furthermore, the stratified analysis revealed that the SH3BGRL3 phenotype could help to refine prognosis in patients. The C-index of the nomogram was 0.740 when combining SH3BGRL3 with other clinicopathological parameters, which indicated a good model for clinical follow-up decisions. Gene functional enrichment analysis also revealed that the DEGs of SH3BGRL3 were mainly enriched in regulating ATP metabolism, ATP synthesis, oxidative phosphorylation and the electron transport chain in GC. Moreover, a higher SH3BGRL3 expression was significantly positively correlated with the infiltrating macrophages in GC. In conclusion, SH3BGRL3 is upregulated in GC, particularly in EBVnGC. Higher SH3BGRL3 expression is closely associated with hyperglycemia and poor outcomes in patients with EBVnGC, suggesting its potential as a biomarker and prognostic predictor.

Early Period Survival and Neurologic Prognosis in Newborns with Perinatal Asphyxia: A Tertiary Center Experience and a Mortality Chart

Background: Clinicians require more data regarding mortality and brain damage risk factors in perinatal asphyxia. Objectives: To assess early term outcomes and identify mortality risk factors in perinatal asphyxia. Methods: This study was conducted in a referral-center tertiary intensive care unit in Istanbul, Turkey, between 2016 and 2023. We included all patients who underwent therapeutic hypothermia treatment due to perinatal asphyxia. We recorded laboratory follow-up data, magnetic resonance imaging (MRI) findings, amplitude-integrated electroencephalograms (aEEG) results, mortality, and clinical outcomes. Both conventional frequentist statistical methods and Bayesian methods were used for analysis. Results: A total of 164 patients were included in the study, with an overall mortality rate of 9.8%. Risk factors for mortality included LDH, troponin I, INR, lactate, 2nd day creatinine, voltage anomalies, seizures, and male gender, as well as APGAR scores. A basic chart for mortality prediction was developed. The Sarnat score showed strong evidence, and APGAR 1 showed anecdotal evidence for association with brain damage, although brain damage was independent of laboratory results and other clinical findings, based on moderate and anecdotal evidence from Bayesian calculations. Cranial MRI findings revealed profound damage in 14.8% of Sarnat 1, 21.8% of Sarnat 2, and 50% of Sarnat 3 patients. Conclusions: This study presents prognostic factors for survival and brain damage in perinatal asphyxia. We recommend obtaining cranial MRI for all patients diagnosed with asphyxia, as most laboratory tests were independent of brain damage. Given that profound brain damage can occur even in Sarnat stage I patients, we emphasize the importance of therapeutic hypothermia for these patients.

MULTIMODAL (5-ALA, TRACTOGRAPHY AND ULTRASOUND GUIDED) AWAKE CRANIOTOMY FOR GLIOBLASTOMA: MAXIMISING SAFE SURGICAL RESECTION

Abstract AIMS Maximising the extent of surgical resection of glioblastoma is a key prognostic factor for survival. This must be balanced against avoiding neurological deficit, which may delay or preclude adjuvant treatments. This is a particular challenge in eloquent tumours. Optimal surgical adjuncts to enable maximal resection of glioblastomas in eloquent brain regions, remain unclear. We present the first series assessing the safety and efficacy of multimodality image-guided, awake resection of IDH-wildtype glioblastoma, combining 5-aminolevulinic acid (5-ALA), diffusion tractography (DTI) and intraoperative ultrasound (USS). METHOD We present a single centre retrospective series of 175 patients undergoing awake craniotomy for primary resection of glioblastomas, between January 2014 and January 2023. Awake craniotomy was considered if tumours were in or adjacent to eloquent areas. Key outcomes assessed included post-operative neurological complications (classified into transient, if persisting &amp;lt;3 months and completely resolved, or permanent if persisting &amp;gt;3 months), extent of resection (EOR) and overall survival (OS). RESULTS 175 patients (103M:72F) were included, with a mean age of 58.2 years. All cases used neuronavigation, whilst 5- ALA and DTI were used in 98.9% and 97.1% of patients respectively. Intraoperative USS was used 88/175 (50.3%). Gross total resection (&amp;gt;98%) was achieved in 101/175 patients (64.7%). 83/175 patients (47.4%) experienced a post-operative neurological deficit, which was temporary in 84.3% (70/83) of cases. When transient deficits occurred, these were most often speech related (49/70). Subgroup analysis found left temporal tumours were highest risk for transient dysphasia (59.2%), followed by left frontal (21.7%) and left parietal (16.0%). The median percentage EOR with USS was 100%, whilst without USS was 97.8% (Wilcox, p=0.0004). CONCLUSION Patients should be counselled about the high risk of transient neurological complications following awake surgery, particularly speech deficit. Multimodal image-guided surgery can maximise the extent of safe resection for glioblastoma.

The Importance of Patient Systemic Health Status in High-Grade Chondrosarcoma Prognosis: A National Multicenter Study

Background: Due to the relatively advanced age and high mortality rate of patients with high-grade chondrosarcoma (CS), it is important to holistically assess patient- and tumor characteristics in multidisciplinary team and shared decision-making with regard to treatment options. While current prognostic models include multiple tumor and treatment characteristics, the only patient characteristics that are commonly included are age and gender. Based on clinical experience, we believe that factors related to patient preoperative systemic health status such as the American Society of Anesthesiologists (ASA) score may be equally important prognostic factors for overall survival (OS). Methods: A retrospective nationwide cohort study was identified from four specialized bone sarcoma centers in The Netherlands. Patients with a primary CS grade II, III, and dedifferentiated CS were eligible. Prognostic factors including age at presentation, gender, ASA score, CVD, tobacco use, BMI, histological tumor grade, tumor size, pathological fracture, presentation after unplanned excision, type of surgery and surgical margin were evaluated. The outcome measure was OS at the time of surgery. The Kaplan–Meier methodology was employed to estimate OS; a log-rank test was used to assess the difference in survival. To study the impact of prognostic factors on OS, a multivariate Cox proportional hazard regression model was estimated. Results: In total, 249 patients were eligible for this study, and 89 were deceased at the end of follow-up. In multivariate analysis, histological grade (HR 2.247, 95% CI 1.334–3.783), ASA score III (HR 2.615, 95% CI 1.145–5.976, vs. ASA I), and age per year (HR: 1.025, 95% CI 1.004–1.045) were negatively associated with OS. No association was found between tobacco use, BMI, gender or cardiovascular disease and OS in this cohort. Pathological fracture and tumor size were only associated with OS in univariate analysis. Conclusions: This multicenter study is the first on sarcomas to include ASA in a prognostic model. Results show that ASA score as a proxy for patients’ systemic health status should be included when providing a prognosis for patients with a high-grade primary CS, besides the conventional risk factors such as tumor grade and age. Specifically, severe systemic disease (ASA score III) is a strong negative predictor. Conversely, we found no difference in OS between ASA scores I and II. These findings aid multidisciplinary team and shared decision-making with regard to these complex sarcoma patients that often require life-changing surgeries. Level of Evidence: Prognostic level III. See the instructions for authors for the complete description of levels of evidence.

The clinical significance of elastic lamina invasion in patients with pStage II colorectal cancer: a notable prognostic indicator

BackgroundSome colorectal cancers (CRCs) are clinically diagnosed as cT4a with serosal invasion (SI). However, the cT4a is most often underdiagnosed pathologically as pT3 without SI by hematoxylin–eosin (H&E) staining alone. Using Elastica van Gieson (EVG) staining, some pT3 tumors invade the elastic lamina (EL), which extends just below the serosal layer. Recently, EL invasion (ELI) has been described as a poor prognostic factor for disease-free survival (DFS) and overall survival (OS) in patients with pStage II CRC. However, its clinicopathological significance remains unclear due to the limited number of studies and poor understanding of ELI.ObjectiveThis study investigated the association between the ELI and patient prognosis.MethodsAfter 1982, pathological diagnosis was routinely performed using H&E and EVG staining methods, and long-term follow up was performed until 2016. All clinicopathological features including ELI were prospectively registered into our computer and 569 patients with pStage II CRC were collected from the database. Based on the ELI status, pT3 was divided into three pathological categories: pT3ELI − was defined as pT3a, pT3ELI + as pT3b and unidentified EL (pT3EL −) as pT3u.ResultsUsing H&E staining alone, gross cT4a was most often pathologically underdiagnosed as pT3 (93.8%) and very rarely as pT4a, resulting in a large diagnostic discrepancy. Using EVG staining, 60.7% of the cT4a tumors were diagnosed as pT3b. The 10-year DFS and OS rates were similar for pT3a and pT3u patients. However, the 10-year DFS and OS rates of pT3b patients were significantly lower than those of pT3a patients (75.6% vs. 95.6%, p < 0.0001 and 58.4% vs. 70.6%, p = 0.0024, respectively) but did not differ from those of pT4a patients (70.6%, p = 0.5799 and 52.0%, p = 0.1116, respectively). Multivariate analysis revealed that the ELI was the strongest independent risk factor for recurrence and CRC-specific death (p < 0.0001).ConclusionsA better understanding of the ELI allows us to reconsider the diagnostic discrepancy of serosal invasion, i.e., pT3b should be considered pT4a. The ELI-based subclassification of pT3 is expected to be incorporated into the TNM staging system in the future. The ELI is a notable prognostic indicator in patients with pStage II CRC.

Survival and prognostic factors for relapsed childhood acute lymphoblastic leukemia after treatment with the Chinese children's cancer group ALL-2015 protocol: a single center results.

This retrospective study was conducted to assess the survival rates and prognostic factors in children with relapsed acute lymphoblastic leukemia (ALL) who were treated according to the Chinese Children's Cancer Group ALL-2015 protocol at the Children's Hospital of Chongqing Medical University. The study cohort involving 852 evaluable children with ALL reported a total of 146 relapses during a median follow-up period of 53 months. The primary outcomes measured were the second complete remission (CR2) rates, and 5-year event-free survival (EFS) and overall survival (OS) for patients who received re-treatment post-relapse. Patient data were stratified by ALL subtype (B-ALL vs. T-ALL), age at relapse, site of relapse, and timing of relapse. Univariate and multivariate analyses were performed to identify factors significantly associated with EFS and OS. As of March 31, 2023, 146 relapses were observed, including 128 B-ALL and 18 T-ALL cases. The 8-year CIR was (19.8 ± 1.6)%, with no significant difference between B-ALL and T-ALL (P=0.271). Among the 105 patients who underwent re-treatment, 70 achieved CR2, resulting in a CR2 rate of 67.6%. The 5-year EFS and OS rates for re-treated patients were (45.0 ± 5.4)% and (56.9 ± 5.2)%, respectively. Significant differences in 5-year OS and EFS were found between B-ALL and T-ALL relapses (P < 0.001). The 5-year EFS and OS varied significantly with relapse timing and site of relapse. Factors significantly affecting EFS after relapse included the site of relapse, immunophenotyping, CR2 achievement, and hematopoietic stem cell transplantation (HSCT). Immunophenotyping, CR2 achievement, and HSCT were also identified as significant factors affecting OS after relapse. Despite treatment with the CCCG-ALL-2015 protocol, a significant relapse rate was observed, with 72% of children opting for re-treatment post-relapse. The study highlights the importance of considering specific prognostic factors to inform tailored treatment strategies for relapsed childhood ALL. The findings emphasize the need for further research into improving therapeutic approaches for this patient population. This retrospective study was conducted to assess the survival rates and prognostic factors in children with relapsed acute lymphoblastic leukemia (ALL) who were treated according to the Chinese Children's Cancer Group ALL-2015 protocol at the Children's Hospital of Chongqing Medical University.

Clinicopathological, immunohistochemical and therapeutic approaches on survival in patients with epithelioid glioblastoma: Institutional experience in the management of 58 patients

Epithelioid glioblastoma (Ep-GBM) is a rare variant of glioblastoma characterized by a high recurrence rate and poor prognosis. Currently, there is no established standard treatment for Ep-GBM. Therefore, we identified 58 Ep-GBM cases to investigate these characteristics and identify the possible prognostic factors of survival. There were 30 male and 28 female patients with a median age of 39 years. Headaches and dizziness were the most common clinical symptom. The tumor is most frequently located in the temporal lobe (36.2%). The positivity rate for BRAF-V600E is 56.9% (33/58), for MGMT is 56.9% (33/58), and for INI-1 is 75% (30/40). Tumor recurrence was observed in 39 patients. The median progression-free survival (PFS) of all patients was 12.7 months, while the median overall survival (OS) was 29.1 months. Additionally, the median survival time after recurrence was 14.3 months. Both univariate and multivariate COX regression analyses revealed that individuals who received more than six cycles of adjuvant oral temozolomide experienced a longer median PFS compared to those who received fewer cycles. Characteristics associated with poorer PFS included tumor dissemination prior to initial surgery. Additionally, both analyses identified tumor dissemination, radiotherapy and adjuvant oral temozolomide as predictors of OS. Notably, for patients with recurrent Ep-GBM, reoperation was shown to significantly increase survival time after recurrence. In conclusion, the standard Stupp regimen is also applicable to patients with Ep-GBM, extending adjuvant oral temozolomide could further improve survival for Ep-GBM patients, reoperation may also prolong survival for recurrent Ep-GBM.

Electrolyte prognosis scoring system can predict overall survival in patients with osteosarcoma.

Osteosarcoma stands as the most prevalent bone tumor, characterized by a heightened tendency for local recurrence and distant metastasis, resulting in a bleak prognosis. Presently, there exists a shortage of novel markers to effectively determine the prognosis of osteosarcoma patients. Recent research indicates that hematological markers partially mirror an individual's microenvironment, offering potential insights into predicting patient prognosis. However, prior studies predominantly focused on the prognostic significance of singular hematological indices, failing to comprehensively represent the tumor microenvironment of patients. In our investigation, we meticulously gathered data on 22 hematological and electrolyte markers, utilizing LASSO Cox regression analysis to devise an Electrolyte Prognostic Scoring System (EPSS). The EPSS encompasses various indicators, including immunity, inflammation, coagulation, and electrolyte levels. Our findings indicate that the EPSS stands as an independent prognostic factor for overall survival among osteosarcoma patients. It serves as a valuable addition to clinical characteristics, adept at discerning high-risk patients from those deemed clinically low-risk. Furthermore, EPSS-based nomograms demonstrate commendable predictive capabilities.

Impact of baseline body mass index on the long-term prognosis of advanced hepatocellular carcinoma treated with immunotherapy.

Primary liver cancer is the sixth most common cancer worldwide, with hepatocellular carcinoma (HCC) being the most prevalent form. Despite the current availability of multiple immune or immune combination treatment options, the prognosis is still poor, so how to identify a more suitable population is extremely important. To evaluate the clinical effectiveness of combining lenvatinib with camrelizumab for patients with hepatitis B virus (HBV)-related HCC in Barcelona Clinic Liver Cancer (BCLC) stages B/C, considering various body mass index (BMI) in different categories. Retrospective data were collected from 126 HCC patients treated with lenvatinib plus camrelizumab. Patients were divided into two groups based on BMI: The non-overweight group (BMI < 25 kg/m2, n = 51) and the overweight/obese group (BMI ≥ 25 kg/m2, n = 75). Short-term prognosis was evaluated using mRECIST criteria, with subgroup analyses for non-overweight (BMI: 18.5-24.9 kg/m2), overweight (BMI: 25-30 kg/m2), and obese (BMI ≥ 30 kg/m2) patients. A Cox proportional hazards regression analysis identified independent prognostic factors for overall survival (OS), leading to the development of a column-line graph model. Median progression-free survival was significantly longer in the obese/overweight group compared to the non-overweight group. Similarly, the median OS was significantly prolonged in the obese/overweight group than in the non-overweight group. The objective remission rate and disease control rate for the two groups of patients were, respectively, objective remission rate (5.88% vs 28.00%) and disease control rate (39.22% vs 62.67%). Fatigue was more prevalent in the obese/overweight group, while other adverse effects showed no statistically significant differences (P > 0.05). Subgroup analysis based on BMI showed that obese and overweight patients had better progression-free survival and OS than non-overweight patients, with obese patients showing the best outcomes. Multifactorial regression analysis identified BCLC grade, alpha-fetoprotein level, portal vein tumor thrombosis, and BMI as independent prognostic factors for OS. The column-line graph model highlighted the importance of BMI as a major predictor of patient prognosis, followed by alpha-fetoprotein level, BCLC classification, and portal vein tumor thrombosis. BMI is a long-term predictor of the efficacy of lenvatinib plus camrelizumab, and obese/overweight patients have a better prognosis.
