Lower 5-year Overall Survival Research Articles

Distinct prognostic impacts of age-adjusted Charlson comorbidity index and geriatric nutritional risk index in patients with intraductal papillary mucinous neoplasm.

The optimal surgical indication for intraductal papillary mucinous neoplasms (IPMN) remains highly contentious. We aimed to determine the preoperative predictive factors of malignancy and independent prognostic factors in patients with IPMN who underwent curative-intent resection. In this study, 104 patients with a pathological diagnosis of IPMN who underwent curative-intent resection were included. Multivariate regression and Cox proportional-hazards analyses were performed to identify the predictive factors for invasive intraductal papillary mucinous carcinoma (IPMC) and prognostic factors for overall survival (OS) after surgery. Among the 104 patients, 24 (23.1%) were pathologically diagnosed with invasive IPMC, and the remaining 80 had low-grade dysplasia or high-grade dysplasia. The presence of high-risk stigmata was an independent predictive risk factor for invasive IPMC. The age-adjusted Charlson comorbidity index (ACCI) (≥4/<4) and geriatric nutritional risk index (GNRI) (<99/≥99) were independent poor prognostic factors for OS (hazard ratio [HR]: 9.39; 95% confidence interval [CI]: 1.90-46.54; P = .006 and HR: 4.37; 95% CI: 1.07-17.86, P = .040, respectively). Forty patients with ACCI ≥ 4 (38.5%) had a significantly lower 5-year OS rate than those with ACCI < 4 (74.3 vs 98.2%, P < .001). Similarly, 29 patients with GNRI < 99 (27.9%) had a significantly lower 5-year OS rate than those with GNRI ≥ 99 (76.0 vs 95.1%, P < .001). These 2 factors were associated with significantly worse disease-specific survival after surgery. The ACCI and GNRI emerged as independent prognostic factors after surgery in patients with IPMN. These findings highlight the importance of patient-conditional factors as valuable indicators for predicting favorable long-term survival outcomes after surgery and for facilitating a more precise assessment of surgical eligibility in patients with IPMN.

Clinical characteristics and prognosis of children with T-lineage acute lymphoblastic leukemia: a single-center study

To study the clinical characteristics and prognosis of T-lineage acute lymphoblastic leukemia (T-ALL) and related prognostic factors. A retrospective analysis was conducted on the children with T-ALL who were treated with the Chinese Children's Cancer Group Acute Lymphoblastic Leukemia (CCCG-ALL) regimen in Guangzhou Women and Children's Medical Center between April 2015 and December 2022. A total of 80 children were included, with a median age of 7 years and 3 months and a male/female ratio of 6:1. Among these children, the children with mediastinal mass accounted for 20% (16/80), those with central nervous system leukemia accounted for 4% (3/80), and those with testicular leukemia accounted for 1% (1/69). SIL/TAL1 was the most common fusion gene (22%, 18/80), and NOTCH1 was the most common mutation gene (69%, 37/54). The median follow-up time was 52 months, with a 5-year overall survival (OS) rate of 87.3%±4.0% and a 5-year event-free survival rate of 84.0%±4.3%. The non-central nervous system-1 group had a significantly lower 5-year OS rate than the central nervous system-1 group (66.7%±16.1% vs 90.3%±3.8%; P<0.05), and the group with minimal residual disease (MRD) ≥0.01% on day 46 of induction therapy had a significantly lower 5-year OS rate than the group with MRD <0.01% (68.6%±13.5% vs 94.8%±3.0%; P<0.05). Children treated with the CCCG-ALL regimen tend to have a good treatment outcome. Non-central nervous system-1 status and MRD ≥0.01% on day 46 of induction therapy are associated with the poor prognosis in these children.

Trends in Cervical and Anal Cancer Incidence and Mortality in the United States.

This article describe trends in the incidence and mortality of cervical (CC) and anal (AC) cancers by race and neighborhood socioeconomic status. The Surveillance, Epidemiology, and End Results (SEER) database was used to construct a cohort of CC and AC cases from 2006 to 2018. Incidence rates and survival were calculated by race and neighborhood socioeconomic status (nSES). Annual percent change (APC) in incidence was calculated using linear regression, and 5-year overall survival (OS) by the Kaplan-Meier method. Of the cases, 33,487 CC and 16,018 AC cases were identified. Women of low nSES were nearly 4 times more likely to be diagnosed with cervical cancer than those of high nSES. Cervical cancer incidence declined marginally in all groups except for low nSES women who are White (APC 0.0). Women who are Black had lower 5-year OS than their nSES counterparts of other races (most notably for Black women of low nSES 53% vs White 63%). Similarly, the low nSES AC cohort contained nearly 3 times the number of diagnoses as the high nSES cohort. AC incidence increased most in women who are White (APC 1.8 and 2.2 for low and high nSES) and men who are Black and low nSES (APC 3.3). Five-year OS was lowest for men who are Asian American and Pacific Islander (40% and 50% for low and high nSES, respectively). These data suggest a strong correlation between nSES, race, and their interaction on the incidence and survival trends of HPV-related disease and highlight inconsistent effects between cervical and anal cancers.

Sociodemographic Factors Influencing Access to Chimeric Antigen T-Cell Receptor Therapy for Patients With Non-Hodgkin Lymphoma

BackgroundChimeric antigen receptor T-cell (CAR-T) therapies are available for patients with Non-Hodgkin Lymphoma (NHL); however, their use has been limited in accessibility due to nondisease factors. Patients & MethodsWe conducted a retrospective study evaluating the influence of sociodemographic factors on access and outcomes after CAR-T therapy for adult patients with B-cell NHL in our institution treated between 2016 and 2023. ResultsAmong 154 patients treated with CAR-T, 43% were older than 65 years, 68% male, and 14% non-White (including Hispanic). Of those under 65, 66% had private insurance, while 82% over 65 had Medicare. Most patients (85%) were from in-state, 29% from areas below the national poverty level and 18% from nonmetropolitan areas. Distance to the treatment center was greater than 30, 60 or 120 miles for 52%, 40% and 29% of patients, respectively. No significant differences were found in the use of commercial versus investigational products among racial/ethnic minorities or those living >60 miles from the center. However, patients from nonmetropolitan areas and those below the national poverty level were less likely to receive commercial products. With a median follow-up of 11 months, the 1-year overall survival (OS) was 63.2% (95th CI 59.9%-66.8%). Poverty was associated with lower 1-year OS (HR 0.4, 95th CI 0.17-0.90, P = .031). ConclusionOur study shows that CAR-T therapy can be delivered across sociodemographic barriers and underscores the importance of considering social determinants of health to optimize access for all patients.

Prognostic significance and treatment strategies for IKZF1 deletion in pediatric B-cell precursor acute lymphoblastic leukemia

BackgroundThe predictive importance of IKZF1del in pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL) has shown variability across different studies. Thus, the optimal treatment approach for children with IKZF1del BCP-ALL remains contentious, with the ongoing debate surrounding the use of IKZF1del-based high-risk stratification versus a minimal residual disease (MRD)-guided protocol.MethodsIKZF1 status was reliably determined in 804 patients using multiplex ligation-dependent probe amplification (MLPA) data obtained from four hospitals in Fujian, a province of China. In the Chinese Children Leukemia Group (CCLG)-ALL 2008 cohort, IKZF1 status was included in the risk assignment, with all IKZF1del patients receiving a high-risk regimen. Conversely, in the Chinese Children’s Cancer Group (CCCG)-ALL 2015 cohort, IKZF1del was not incorporated into the risk assignment, and patients were treated based on an MRD-guided risk stratification protocol.ResultsIKZF1del was found in 86 patients (86/804, 10.7%) overall and in 30 (30/46, 65.2%) BCR::ABL1-positive patients. Overall, IKZF1del was a poor prognostic predictor for patients, though the significance diminished upon age adjustment, white blood cell (WBC) count at diagnosis, treatment group, and MRD status. In the CCLG-ALL 2008 cohort, IKZF1del conferred a notably lower 5-year overall survival (OS) and event-free survival (EFS) and a significantly higher 5-year cumulative incidence of relapse (CIR) than IKZF1wt. In the CCLG-ALL 2015 cohort, IKZF1del conferred a lower 5-year OS and EFS and a higher 5-year CIR than IKZF1wt, but the differences were insignificant. The IKZF1del patients treated with higher intensity chemotherapy (CCLG-ALL 2008 high-risk regimen) had a markedly lower 5-year OS and EFS compared with those treated with the MRD-guided protocol (CCCG-ALL 2015 protocol). Furthermore, patients treated with the CCLG-ALL 2008 high-risk regimen experienced a higher frequency of serious adverse events (SAEs), especially infection-related SAEs, compared with those treated with the CCCG-ALL 2015 MRD-guided protocol.ConclusionsThe prognostic effect of IKZF1del may vary in different protocols. Compared with higher intensity chemotherapy, the MRD-guided protocol may be a more effective approach to treating BCP-ALL with IKZF1del in children.

The prognostic value of image-identified extranodal extension in laryngeal and hypopharyngeal carcinoma following definitive (chemo-)radiotherapy

ObjectivesClinical extranodal extension (cENE) is a cN modifier in TNM-8 for laryngo-hypopharygeal carcinoma (LHC). We hypothesize that image-detected ENE (iENE) can provide additional prognostic value over cENE in LHC. MethodsBaseline CTs/MRIs of cN+ LHC patients treated with definitive (chemo-)radiotherapy between 2010–2019 were re-reviewed by a neuroradiologist using internationally accepted criteria for iENE-positive/negative (iENE+/iENE–). Overall survival (OS) was compared by iENE status. Multivariable analysis (MVA) was performed to confirm the prognostic value of iENE, adjusted for known potential confounders. ResultsA total of 232 LHC patients were identified, including 154 iENE–/cENE–, 60 iENE+/cENE–, and 18 iENE+/cENE+. A higher proportion of iENE+ (vs iENE–) patients had lymph node (LN) size > 3 cm [53 (67 %) vs 4 (3 %)], >=5 LNs [51 (65 %) vs 33 (21 %)], and retropharyngeal LN [12 (15 %) vs 6 (4 %)] (all p < 0.01). Median follow-up was 4.8 years. iENE+/cENE– and iENE+/cENE+patients had similarly low 5-year OS [28 % (18–44) and 29 % (13–63)] vs iENE–/cENE– [53 % (45–62)] (p < 0.001). On MVA, mortality risk was higher with iENE+vs iENE– [hazard ratio (HR) 2.22 (95 % CI 1.47–3.36)]. The prognostic value of iENE remained with MVA in larynx (n = 124) (HR 2.51 [1.35–4.68], p = 0.004] or hypopharynx (n = 108) (HR 1.87 [1.02–3.43], p = 0.04) patients, separately. ConclusionsOur study confirms the independent prognostic importance of iENE for LHC following definitive (chemo-)radiotherapy beyond TNM-8 cN status that already contains the cENE parameter. Further research is needed to explore whether iENE could replace cENE for future cN classification.

Survival Analysis and Recurrence Patterns in 555 Patients with Colorectal Peritoneal Metastases Treated by Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

The presence at diagnosis, or development of, colorectal peritoneal metastases (CPM) is common in colorectal cancer. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) show promising results in selected patients with CPM. The current study aimed to describe oncologic outcomes of patients with CPM, focusing on recurrence patterns and risk factors for adverse events. We conducted a retrospective review of patients with CPM treated by CRS and HIPEC at a single institution between 2000 and 2021. A total of 555 patients were included, of whom 480 (86.5%) had complete cytoreduction, with a median age of 59 years and median Peritoneal Cancer Index (PCI) of 6. Following complete cytoreduction, 5-year overall survival (OS) and disease-free survival (DFS) were 51% and 31%, respectively. In multivariable Cox regression, PCI >6 (hazard ratio [HR] 2.25), pathological node positivity (pN+; HR 1.94), and perineural invasion (HR 1.85) were associated with decreased OS, while PCI >6, pN+, and previous systemic metastases resulted in reduced DFS. Overall, 284 (62%) patients developed recurrence, of whom 97 (34%) had local recurrence (LR), 100 (35%) had systemic recurrence (SR), and 87 (31%) had combined recurrence (5-year OS: 49.3%, 46%, and 37.4%, respectively). Mutated KRAS (mKRAS) was associated with lower 5-year OS (55.8%) and DFS (27.9%) compared with wild-type KRAS (wtKRAS; 70.7% and 37.6%, respectively). In multivariable analyses, mKRAS was related to decreased OS (HR 1.82), DFS (HR 1.55), and SR (OS 1.89), but not to LR. Complete cytoreduction results in good survival outcomes for patients with CPM. Burden of peritoneal disease and tumor biology are the main predictors of survival. Patients with mKRAS are a high-risk cohort, with increased probability of SR and reduced survival.

Efficacy of WT1 gene-guided pre-emptive therapy for prevention of relapse in acute myeloid leukemia after transplantation and its optimal intervention threshold.

Monitoring minimal residual disease (MRD) and timely intervention are effective strategies for preventing relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adult acute myeloid leukemia (AML). The WT1 gene, a pan-leukemia marker, can be used as an indicator for MRD monitoring in AML patients. Currently, there is no unified standard for the intervention timing or treatment threshold based on WT1 gene detection after transplantation. This study aims to evaluate the clinical value of WT1 gene-guided preemptive therapy and further explore its optimal intervention threshold. Data of adult AML patients with intermediate or high-risk cytogenetics who underwent allo-HSCT between January 2014 and June 2020 at the Department of Hematology, Xiangya Hospital, Central South University, were retrospectively collected. All patients had WT1 gene expression data within three years post-transplantation. We compared the outcomes of WT1-positive patients who received preemptive therapy with those who did not, and both groups with WT1-negative patients. The endpoints analyzed included cumulative incidence of relapse (CIR), disease-free survival (DFS) rate, overall survival (OS) rate, and non-relapse mortality (NRM) rate. Data of patients who did not receive any intervention were included to analyze factors that might influence prognosis. Univariate analysis was performed using factors such as age, gender, transplantation type,cytogenetic risk stratification, pre-transplant disease status, pre- and post-transplant WT1 levels, and donor gender; factors with P<0.10 in univariate analysis were further included in a Cox regression model for multivariate analysis. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off value of WT1 gene expression for predicting relapse. A total of 165 AML patients were included, of whom 86 had WT1 gene positivity within three years post-transplantation. Among these, 58 received preemptive therapy and 28 did not. Compared with WT1-negative patients, those WT1-positive patients who did not receive preemptive therapy had significantly higher 5-year CIR (42.9% vs 10.5%, P<0.001), lower 5-year DFS (50.0% vs. 80.7%, P=0.001), and lower 5-year OS (60.7% vs 82.8%, P=0.018), while the 5-year NRM rates were not significantly different (7.1% vs 8.9%, P=0.744). For patients who received preemptive therapy, no significant differences in these outcomes were observed (all P>0.05). Multivariate analysis revealed that post-transplantation WT1 gene positivity was a poor prognostic factor for AML patients (CIR: HR=6.24, P=0.000 1; DFS: HR=2.77, P=0.009 6). ROC curve analysis indicated that the area under the curve (AUC) for WT1 gene expression predicting post-transplantation relapse within 3 years was 0.727 (95% CI 0.582 to 0.873), with an optimal cut-off value of 122 copies, sensitivity of 60.0%, and specificity of 89.9%. sequential monitoring of WT1 gene expression in intermediate- or high-risk AML patients after allo-HSCT within 3 years, with timely preemptive therapy for those who become WT1-positive, can effectively reduce relapse and improve prognosis. A WT1 gene expression level of 120 copies may be a more precise and reliable intervention threshold for preemptive therapy.

The Effects of Sarcopenia on Overall Survival and Postoperative Complications of Patients Undergoing Hepatic Resection for Primary or Metastatic Liver Cancer: A Systematic Review and Meta-Analysis.

Background: Colorectal cancer is the third most common cancer worldwide, and 20-30% of patients will develop liver metastases (CRLM) during their lifetime. Hepatocellular carcinoma (HCC) is also one of the most common cancers worldwide with increasing incidence. Hepatic resection represents the most effective treatment approach for both CRLM and HCC. Recently, sarcopenia has gained popularity as a prognostic index in order to assess the perioperative risk of hepatectomies. The aim of this study is to assess the effects of sarcopenia on the overall survival (OS), complication rates and mortality of patients undergoing liver resections for HCC or CRLM. Methods: A systematic literature search was performed for studies including patients undergoing hepatectomy for HCC or CRLM, and a meta-analysis of the data was performed. Results: Sarcopenic patients had a significantly lower 5-year OS compared to non-sarcopenic patients (43.8% vs. 63.6%, respectively; p < 0.01) and a significantly higher complication rate (35.4% vs. 23.1%, respectively; p = 0.002). Finally, no statistical correlation was found in mortality between sarcopenic and non-sarcopenic patients (p > 0.1). Conclusions: Sarcopenia was significantly associated with decreased 5-year OS and increased morbidity, but no difference was found with regard to postoperative mortality.

Preoperative BMI and long-term survival in NAFLD-associated hepatocellular carcinoma: A multicenter study revealing a paradox.

e16262 Background: As non-alcoholic fatty liver disease (NAFLD) emerges as a key factor in hepatocellular carcinoma (HCC) development, exacerbated by the global obesity epidemic, the prognostic role of body mass index (BMI) in NAFLD-HCC patients undergoing surgical resection remains unclear. This study aims to elucidate the impact of preoperative BMI on long-term outcomes after hepatectomy in patients with NAFLD-HCC, offering insights for more personalized treatment strategies. Methods: In this multicenter retrospective study, patients with early-stage (BCLC stage 0/A) NAFLD-HCC who underwent curative hepatectomy between 2009 and 2022 were analyzed. Based on preoperative BMI, patients were classified into lean ( &lt; 23.0 kg/m2), overweight (23.0-27.4 kg/m2), and obese (≥ 27.5 kg/m2) categories. The primary endpoints, overall survival (OS) and recurrence-free survival (RFS), were compared across these BMI groups. Results: This large multicenter cohort comprised 309 early-stage NAFLD-HCC patients: 66 lean, 176 overweight, and 67 obese. Liver-, tumor-, and surgery-related characteristics were similar across groups. Lean patients exhibited significantly lower 5-year OS and RFS (55.4% and 35.1%, respectively) compared to overweight patients (71.3% and 55.6%, P = 0.017 and P = 0.002), with outcomes comparable to obese patients (48.5% and 38.2%, P = 0.939 and P = 0.442). Multivariable Cox-regression analysis revealed lean BMI, but not obese BMI, as an independent predictor of decreased OS (HR: 1.69; 95%CI: 1.06-2.71; P = 0.029) and RFS (HR: 1.72; 95% CI: 1.17-2.52; P = 0.006). Conclusions: This study challenges conventional perceptions of BMI in cancer prognosis, revealing that lean NAFLD-HCC patients have poorer long-term surgical outcomes compared to their overweight and obese counterparts. These findings underscore the need for a nuanced understanding of BMI’s role in NAFLD-HCC management and prompt further investigation into the underlying biological mechanisms of this paradox.

Laparoscopic versus open hepatectomy for exophytic hepatocellular carcinoma: A multicenter propensity-matched comparative study.

e16268 Background: As laparoscopic hepatectomy (LH) gains traction in the surgical management of hepatocellular carcinoma (HCC), its efficacy for exophytic HCC, a subtype with unique surgical challenges, remains under scrutiny. This study aims to compare the long-term outcomes of LH with traditional open hepatectomy (OH) in treating exophytic HCC. Methods: A multicenter retrospective analysis was conducted on patients with solitary exophytic HCC undergoing LH or OH at 10 hepatobiliary centers. Propensity score matching (PSM) and inverse probability treatment weighting (IPTW) were employed to balance the LH and OH groups for overall survival (OS) and recurrence-free survival (RFS) comparisons. Multivariable Cox-regression analysis determined the independent impact of surgical approach on OS and RFS. Results: The study included 270 patients, with 132 undergoing OH and 138 LH. Post-PSM, 97 matched pairs were analyzed. In this cohort, LH was associated with significantly lower 5-year OS (36.1% vs. 53.5%, P = 0.021) and RFS (31.7% vs. 44.9%, P = 0.013) compared to OH. Additionally, LH patients exhibited a higher rate of abdominal seeding metastases (19.6% vs. 8.2%, P = 0.023). Multivariable analysis in the PSM cohort revealed LH as an independent factor for reduced OS (HR, 1.62; 95% CI, 1.06-2.47; P = 0.025) and RFS (HR, 1.79; 95% CI, 1.22-2.64; P = 0.003), corroborated by IPTW cohort findings. Conclusions: This study indicates that LH may be less favorable than OH for exophytic HCC, potentially contraindicating its use in such cases. These findings highlight the necessity for further prospective research to refine surgical protocols for exophytic HCC.

Neoadjuvant chemotherapy followed by surgery versus concurrent chemoradiotherapy in patients with stage IIB cervical squamous cell carcinoma: a retrospective cohort study

PurposeThis study aims to compare treatment outcomes between neoadjuvant chemotherapy (NACT) followed by surgery and concurrent chemoradiotherapy (CCRT) in patients with stage IIB cervical squamous cell carcinoma (CSCC).Materials and methodsWe conducted a retrospective cohort study involving patients with stage IIB CSCC treated at Guangxi Medical University Cancer Hospital between June 2012 and June 2019. We compared overall survival (OS), locoregional-free survival (LRFS), and distant metastasis-free survival (DMFS) between the NACT + surgery and CCRT groups.ResultsA total of 257 patients were enrolled: 165 underwent NACT + surgery and 92 received CCRT. Before propensity score matching, the NACT + surgery group exhibited lower 5-year OS (68.2% vs. 85.6%; hazard ratio [HR] = 2.50, 95% confidence interval [CI]: 1.26–4.96; P = 0.009), LRFS (85.2% vs. 96.9%; HR = 5.88, 95% CI: 1.33–25.94; P = 0.019), and DMFS (81.9% vs. 97.4%; HR = 6.65, 95% CI: 1.51–29.23; P = 0.012) compared to the CCRT group. After propensity score matching, OS, LRFS, and DMFS remained worse in the NACT + surgery group compared to the CCRT group.ConclusionNACT followed by surgery is associated with decreased OS, LRFS, and DMFS compared to CCRT among patients with stage IIB CSCC.

Prognostic analysis of childhood T-lymphoblastic lymphoma treated with leukemia regimen

To investigate the prognosis of childhood T-lymphoblastic lymphoma (T-LBL) treated with acute lymphoblastic leukemia (ALL) regimen and related influencing factors. A retrospective analysis was performed for the prognostic characteristics of 29 children with T-LBL who were treated with ALL regimen (ALL-2009 or CCCG-ALL-2015 regimen) from May 2010 to May 2022. The 29 children with T-LBL had a 5-year overall survival (OS) rate of 84%±7% and an event-free survival (EFS) rate of 81%±8%. The children with B systemic symptoms (unexplained fever >38°C for more than 3 days; night sweats; weight loss >10% within 6 months) at initial diagnosis had a lower 5-year EFS rate compared to the children without B symptoms (P<0.05). The children with platelet count >400×109/L and involvement of both mediastinum and lymph nodes at initial diagnosis had lower 5-year OS rates (P<0.05). There were no significant differences in 5-year OS and EFS rates between the children treated with CCCG-ALL-2015 regimen and those treated with ALL-2009 regimen (P>0.05). Compared with the ALL-2009 regimen, the CCCG-ALL-2015 regimen reduced the frequency of high-dose methotrexate chemotherapy and the incidence rate of severe infections (P<0.05). The ALL regimen is safe and effective in children with T-LBL. Children with B systemic symptoms, platelet count >400×109/L, and involvement of both mediastinum and lymph nodes at initial diagnosis tend to have a poor prognosis. Reduction in the frequency of high-dose methotrexate chemotherapy can reduce the incidence rate of severe infections, but it does not affect prognosis.

The differential expression of AFF3 in cervical cancer and its correlation with clinicopathological features and prognosis

Background Cervical cancer (CC) is the second most common malignancy in women, and identifying biomarkers of CC is crucial for prognosis prediction. Here, we investigated the expression of AF4/FMR2 Family Member 3 (AFF3) in CC and its association with clinicopathological features and prognosis. Methods Tumour and adjacent tissues, along with clinicopathological features and follow-up information, were collected from 78 patients. AFF3 expression was assessed using quantitative real-time polymerase chain reaction and Western blotting. The correlation between AFF3 expression and CC symptoms was using chi-square test. The 5-year overall survival (OS) was analysed using the Kaplan-Meier method. The Univariate analysis of prognostic risk factors was conducted using the COX proportional hazards model, followed by multivariate COX regression analysis including variables with p < 0.01. Results AFF3 expression was downregulated in CC, and its levels were correlated with lymph node metastasis (LNM) and International Federation of Gynaecology and Obstetrics (FIGO) stage. Patients with low AFF3 expression had a lower 5-year OS rate (52.78%, 19/36). Postoperative survival was reduced in patients with histological grade 3 (G3), myometrial invasion (depth ≥ 1/2), lymphovascular space invasion, LNM, and advanced FIGO stage. Low expression of AFF3 (HR: 2.848, 95% CI: 1.144–7.090) and histological grade G3 (HR: 4.393, 95% CI: 1.663–11.607) were identified as independent prognostic risk factors in CC patients. Conclusion Low expression of AFF3 and histological G3 are independent predictors of poor prognosis in CC patients, suggesting that AFF3 could serve as a potential biomarker for prognostic assessment in CC.

The evolution and impact of sarcopenia in severe aplastic anaemia survivors following allogeneic haematopoietic cell transplantation.

Sarcopenia is a potential risk factor for adverse outcomes in haematopoietic cell transplantation (HSCT) recipients. We aimed to explore longitudinal body changesin muscle and adipose mass and their prognostic value in allogeneic HSCT-treated severe aplastic anaemia (SAA) patients. We retrospectively analysed consecutive SAA patients who underwent allogeneic HSCT between January 2017 and March 2022. Measurements of pectoral muscle and corresponding subcutaneous fat mass were obtained via chest computed tomography at baseline and at 1month, 3months, 6months, and 12months following HSCT. Sarcopenia was defined as pectoral muscle index (PMI) lower than the sex-specific median at baseline. Changes in body composition over time were evaluated by generalized estimating equations. Cox regression models were used to investigate prognostic factors affecting overall survival (OS) and failure-free survival (FFS). A nomogram was constructed from the Cox regression model for OS. We included 298 adult SAA patients (including 129 females and 169 males) with a median age of 31years [interquartile range (IQR), 24-39years] at baseline. Sarcopenia was present in 148 (148/298, 50%) patients at baseline, 218 (218/285, 76%) patients post-1month, 209 (209/262, 80%) patients post-3month, 169 (169/218, 78%) patients post-6month, and 129 (129/181, 71%) patients post-12month. A significant decrease in pectoral muscle mass was observed in SAA patients from the time of transplant to 1year after HSCT, and the greatest reduction occurred in post 1-3months (P<0.001). The sarcopenia group exhibited significantly lower 5-year OS (90.6% vs. 100%, log-rank P=0.039) and 5-year FFS (89.2% vs. 100%, log-rank P=0.021) than the nonsarcopenia group at baseline. Sarcopenia at baseline (hazard ratio, HR, 6.344; 95% confidence interval, CI: 1.570-25.538; P=0.01; and HR, 3.275; 95% CI: 1.159-9.252; P=0.025, respectively) and the delta value of the PMI at 6months post-transplantation (ΔPMI6) (HR, 0.531; 95% CI: 0.374-0.756; P<0.001; and HR, 0.666; 95% CI: 0.505-0.879; P=0.004, respectively) were demonstrated to be independent prognostic factors for OS and FFS in SAA patients undergoing HSCT, and were used to construct the nomogram. The C-index of the nomogram was 0.75, and the calibration plot showed good agreement between the predictions made by the nomogram and actual observations. Sarcopenia persists in SAA patients from the time of transplant to the 1-year follow-up after HSCT. Both sarcopenia at baseline and at 6months following HSCT are associated with poor clinical outcomes, especially in patients with persistent muscle mass loss up to 6months after transplantation.

Abstract 4871: Colorectal cancer incidence and overall survival by race, stage, and age: A SEER database analysis, 2009-2020

Abstract Introduction: In the United States, colorectal cancer (CRC) is the fourth most common cancer and the second leading cause of cancer-related deaths. Although incidence rates of CRC have been decreasing overall, recent studies suggest a shift in demographics, specifically an increase in the number of new CRC cases among younger individuals and a higher incidence among those who identify as non-Hispanic Native American/Alaska Native. To examine the latest trends in incidence and overall survival (OS) among adults with CRC in the United States, we conducted an observational study using the Surveillance, Epidemiology, and End Results (SEER) Program database. Methods: Patients aged ≥18 years with newly diagnosed CRC between January 1, 2009, and December 31, 2020 were identified in the SEER 17 database. Age-adjusted incidence rates for CRC were calculated by race/ethnicity and age groups (18-49, 50-64, and ≥65 years) from 2009 to 2020. Kaplan-Meier curves were generated to examine 5-year OS by race/ethnicity, stage, and age groups. Results: There were 429,218 CRC cases identified with a median age of 67 years. Most were male (52.4%) with stage 0-II CRC (51.4%). Most patients identified as non-Hispanic White (66.3%), followed by non-Hispanic Black (11.5%), non-Hispanic Asian/Pacific Islander (8.9%), non-Hispanic Native American/Alaska Native (0.7%), and Hispanic of any race (12.7%). The age-adjusted incidence rate between 2009 and 2020 was 51.9 per 100,000 persons; incidence decreased from 59.5 per 100,000 persons in 2009 to 44.2 per 100,000 persons in 2020, with male patients having a higher incidence rate than female patients. By 2020, non-Hispanic Native American/Alaska Native patients had the highest incidence rate (54.5 per 100,000 persons) followed by non-Hispanic Black patients (50.6 per 100,000 persons). CRC incidence rates increased slightly for age &amp;lt;50 years (10.5 to 12.9 per 100,000 persons) and decreased for ages 50-64 (74.6 to 63.9 per 100,000 persons) and ≥65 years (222.4 to 136.1 per 100,000 persons). Non-Hispanic Black patients (53%), age ≥65 years (47%), and those with stage III-IV CRC (41%) had a lower 5-year OS from 2015 to 2019 compared to patients who were non-Hispanic White (57%), aged 50-64 (68%) and &amp;lt;50 years (70%), and with stage 0-II CRC (77%). Conclusion: Our results confirm a slight increase in CRC incidence among younger (&amp;lt;50 years) individuals over the 2009-2020 time period. Patients who were non-Hispanic Native American/Alaska Native had the highest CRC incidence rate and patients who were non-Hispanic Black had the poorest OS. Targeted preventative efforts such as CRC screening programs in addition to improved access to care/treatment may be needed to reduce the number of new cases and improve outcomes among historically underserved groups.

The association of postoperative morbidity and age on 5-year survival after colorectal surgery in the elderly population: a nationwide cohort study.

This study aimed to evaluate the association of age and postoperative morbidity on 5-year overall survival (OS) after elective surgery for colorectal cancer. Patients undergoing elective, curatively intended surgery for colorectal cancer Union for International Cancer Control Stages I-III between January 2014 and December 2019 were selected from four Danish nationwide healthcare databases. Patients were divided into four groups: group I 65-69 years old; group II 70-74 years old; group III 75-79 years old; and group IV ≥80 years old. Propensity score matching was used to reduce potential confounding bias. The primary outcome was the association of age and postoperative morbidity with 5-year OS. The secondary outcome was conditional survival, given that the patient had already survived the first 90 days after surgery. After propensity score matching with a 1:1 ratio, group II contained 2221 patients; group III 952 patients; and group IV 320 patients. There was no significant difference in 5-year OS between group I (reference) and groups II and III (P = 0.4 and P = 0.9, respectively). Patients with severe postoperative complications within 30 days after surgery had a significantly decreased OS (P < 0.01); however, when patients who died within the first 90 days were excluded from the analysis, the differences in 5-year OS were less pronounced across all age groups. Postoperative morbidity, and not patient age, was associated with a lower 5-year OS. Long-term survival for patients who experience a complication is similar to patients who did not have a complication when conditioning on 90 days of survival.

Influence of nutritional status and body composition on postoperative events and outcome in patients treated for primary localized retroperitoneal sarcoma.

Retroperitoneal sarcomas (RPS) are rare tumours of mesenchymal origin, commonly presented as a large tumour mass at time of diagnosis. We investigated the impact of body composition on outcome in patients operated on for primary localized RPS. We retrospectively analysed data for all patients operated on for primary RPS at our institution between 1999 and 2020. Preoperative skeletal muscle area (SMA), visceral and subcutaneous adipose tissue area (VAT and SAT) and muscle radiation attenuation (MRA) were calculated using computed tomography scans at the level of third lumbar vertebra. European Working Group on Sarcopenia in Older People (EWGSOP2) criteria were applied to define myopenia. Using maximum log-rank statistic method we determined the optimal cut-off values of body composition parameters. Myosteatosis was defined based on determined MRA cut-offs. In total 58 patient were eligible for the study. With a median follow-up of 116 months, the estimated 5-year overall survival (OS) and local-recurrence free survival (LRFS) were 66.8% and 77.6%, respectively. Patients with myopenia had significantly lower 5-year OS compared to non-myopenic (p = 0.009). Skeletal muscle index and subcutaneous adipose tissue index predicted LRFS on univariate analysis (p = 0.052 and p = 0.039, respectively). In multivariate analysis high visceral-to-subcutaneous adipose tissue area ratio (VSR) independently predicted higher postoperative complication rate (89.2% vs. 10.8%, p = 0.008). Myosteatosis was associated with higher postoperative morbidity. Myopenia affected survival, but not postoperative outcome in RPS. Visceral obesity, VSR (> 0.26) and myosteatosis were associated with higher postoperative morbidity. VSR was better prognostic factor than VAT in RPS.

Gross total resection and survival outcomes in elderly patients with spinal chordoma: a SEER-based analysis.

The association between aggressive resection and improved survival for adult spinal chordoma patients has not been well characterized in the geriatric population. Thus, the present study aimed to elucidate the relationship between gross total resection (GTR) and survival outcomes for patients across different age groups. The authors isolated all adult patients diagnosed with spinal chordoma from the 2000-2019 Surveillance, Epidemiology, and End Results database and divided patients into three surgical subgroups: no surgery, subtotal resection (STR), and GTR. Kaplan-Meier curves with a log-rank test were used to discern differences in overall survival (OS) between surgical subgroups. Univariate and multivariate analyses were used to identify prognostic factors of mortality. There were 771 eligible patients: 227 (29.4%) received no surgery, 267 (34.6%) received STR, and 277 (35.9%) received GTR. Patients receiving no surgery had the lowest 5-year OS (45.2%), 10-year OS (17.6%), and mean OS (72.1 months). After stratifying patients by age, our multivariate analysis demonstrated that patients receiving GTR aged 40-59 (HR=0.26, CI=0.12-0.55, p<0.001), 60-79 (HR=0.51, CI=0.32-0.82, p=0.005), and 80-99 (HR=0.14, CI=0.05-0.37, p<0.001) had a lower risk of mortality compared to patients undergoing no surgery. The frequency of receiving GTR also decreased as a function of age (16.4% [80-99 years] vs. 43.2% [20-39 years]; p<0.001), but the frequency of receiving radiotherapy was comparable across all age groups (48.3% [80-99 years] vs. 45.5% [20-39 years]; p=0.762). GTR is associated with improved survival for middle-aged and elderly patients with spinal chordoma. Therefore, patients should not be excluded from aggressive resection on the basis of age alone. Rather, the decision to pursue surgery should be decided on an individual basis.

Prognosis of Stage I Endometrial Cancer According to the FIGO 2023 Classification Taking into Account Molecular Changes.

Optimum risk stratification in an early stage of endometrial cancer (EC) combines molecular and clinicopathological features. The purpose of the study was to determine the prognostic value of molecular classification and traditional pathological factors in a sample group of patients with stage I EC according to the FIGO 2023 criteria, to achieve a more personalized approach to patient care and treatment. The immunohistochemistry for p53 and mismatch repair (MMR) proteins, and DNA sequencing for POLE exonuclease domain and clinicopathological parameters, including disease disease-free survival (DFS) and overall survival (OS) in 139 patients, were analyzed. It has been shown that the independent recurrence risk factors are stage IC (p < 0.001), aggressive histological types EC (p < 0.001), and the presence of p53abn protein immunoexpression (p = 0.009). Stage IC (p = 0.018), aggressive histological types EC (p = 0.025) and the presence of p53abn protein immunoexpression (p = 0.010) were all significantly associated with lower 5-year OS rates. Our research studies confirm that the molecular category corresponds to a different prognosis in clinical stage I EC according to the new 2023 FIGO classification, with POLEmut cases presenting the best outcomes and p53abn cases showing the worst outcomes. Beyond the previous routine clinicopathological assessment, the new EC staging system represents an important step toward improving our ability to stratify IC stage EC risk.
