Lower 5-year Overall Survival Rate Research Articles

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.

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.

Prognostic value of NT-proBNP and uric acid in acute ST-segment elevation myocardial infarction patients after complete revascularization.

To explore the prognostic value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and uric acid (UA) in acute ST-segment elevation myocardial infarction (STEMI) patients after complete revascularization (CR). The clinical and physical data from 125 acute STEMI patients (research group) who underwent CR between December 2017 and December 2020 and 60 healthy individuals (control group) who concurrently underwent physical examinations in the Affiliated Hospital of Guizhou Medical University were retrospectively analyzed in this study. Serum samples were collected from both groups to determine the levels of NT-proBNP and UA. The 3-year follow-up data of acute STEMI patients were collected, which were used to group the patients into a good and a poor prognosis group based on their prognoses to comparatively analyze NT-proBNP and UA levels. Receiver operating characteristic (ROC) curves were drawn to analyze the prognostic value of NT-proBNP and UA in STEMI patients following CR, and survival curves were plotted to observe their influences on patients' 3-year overall survival (OS). Meanwhile, a univariate analysis was conducted to identify factors associated with the 3-year OS of acute STEMI patients after CR. The data showed significantly higher expression levels of serum NT-proBNP and UA in acute STEMI patients than in the controls. Besides, the good prognosis group exhibited markedly lower serum NT-proBNP and UA levels than the poor prognosis group. The areas under the curve (AUCs) of NT-proBNP and UA in predicting the prognosis of acute STEMI patients after CR were all above 0.700, and the AUC of their combined detection reached over 0.800. In addition, high serum NT-proBNP and UA levels were strongly associated with lower 3-year OS rates. As indicated by the univariate analysis, a history of smoking and alcoholism as well as high NT-proBNP and UA levels were closely associated with 3-year OS in acute STEMI patients after CR. NT-proBNP and UA have promising prognostic value in acute STEMI after CR.

Time to Local Recurrence as a Predictor of Survival in Adult Head and Neck Soft Tissue Sarcoma.

We sought to evaluate the impact of the time interval from surgical resection to local recurrence (TTLR) on clinical outcomes in head and neck soft tissue sarcoma (HNSTS). A total of 401 patients who underwent R0 resection for primary HNSTS were included in this study. Patients with local recurrence as the first event after their initial resection were divided into early local recurrence (ELR) or late local recurrence (LLR) groups according to TTLR. Multiple survival analyses were performed to identify the independent prognostic predictors of overall survival (OS) and survival after local recurrence (SAR). Two hundred and nine of the 401 patients (52.1%) developed local recurrence during a median follow-up period of 134.6 months. Patients in the ELR group had a shorter median OS time (35.0 vs. 120.6, p < 0.001) and lower 5-year OS rate (47.7% vs. 80.9%, p < 0.001) than those in the LLR group. Moreover, the ELR group exhibited worse SAR (p=0.001) than the LLR group, and multivariate analyses demonstrated TTLR as an independent prognostic factor for SAR (p=0.048) and OS (p=0.004). Additionally, re-resection significantly prolonged SAR than other salvage interventions or no treatment (p < 0.001). In patients with HNSTS, ELR after R0 resection presents adverse effects on OS and SAR than those with LLR, and TTLR could serve as a promising predictor for survival. Salvage therapies, especially the re-resection could improve SAR and should be recommended when there are surgical indications after recurrence. 3 Laryngoscope, 133:2174-2182, 2023.

D-dimer, a predictor of bad outcome in gastric cancer patients undergoing radical resection

As a marker of hypercoagulability, plasma D-dimer is associated with progression of many cancers but remains controversial in gastric cancer (GC). We aim to investigate the predictive value of D-dimer for postoperative outcomes after radical gastrectomy of GC patients. We enrolled 903 consecutive patients with GC who underwent radical gastrectomy and the clinicopathological characteristics were compared. Risk factors for overall survival (OS) and disease-free survival (DFS) were determined using multivariate cox regression analysis. We also compared the survival difference based on Kaplan–Meier method after a one-to-one propensity score matching (PSM). Patients with elevated D-dimer had older age (p < 0.001), advanced TNM stage (p < 0.001), larger tumor size (p = 0.005), lower 5-year OS rate (32.8% vs 62.6%, p < 0.001) and DFS (29% vs 59.6%, p < 0.001). In multivariate analysis, elevated D-dimer was independently associated with shorter OS [hazard ratio (HR): 1.633, 95% confidence interval (CI) 1.178–2.264, p = 0.003] and DFS (HR: 1.58, 95% CI 1.151–2.169, P = 0.005). After PSM, the 5-year OS rate of patients with elevated D-dimer was still significantly lower than matched group (32.8% vs 40.6%, p = 0.005), so was DFS (29% vs 36.6%, p = 0.008). Preoperative elevated D-dimer is an independent risk factor for GC patients undergoing curative gastrectomy.

Impact of time to first relapse on long-term outcome in adult retroperitoneal sarcoma patients after radical resection

BackgroundLocal recurrence of primary retroperitoneal sarcoma (RPS) is one of the major causes of treatment failure and death. We attempted to assess the effects of time to local recurrence (TLR) on the survival after recurrence (SAR) and overall survival (OS) of RPS.MethodsIncluded in this study were 224 patients who underwent R0 resection for primary RPS at our institution between January 2000 and December 2020, 118 of whom had local recurrence. Based on the median TLR (19.8 months), patients were divided into two groups: early local recurrence (ELR < 20 months) and late local recurrence (LLR > 20 months). The Kaplan–Meier method was employed to calculate the local recurrence-free survival (LRFS), SAR and OS. Univariate and multivariate analyses were conducted to explore the prognostic value of TLR.ResultsThe median follow-up time was 60.5 months for the entire cohort and 58.5 months for the recurrence cohort. There were 60 (50.8%) patients in the ELR group and 58 (49.2%) in the LLR group. The ELR group exhibited a worse SAR (29.2 months vs. 73.4 months, P < 0.001), OS (41.8 months vs. 120.9 months, P < 0.001), and a lower 5-year OS rate (35.9% vs. 73.2%, P = 0.004) than the LLR group. Furthermore, multivariate analysis indicated that TLR was an independent prognostic indicator for SAR (P = 0.014) and OS (P < 0.001).ConclusionsIn patients with RPS, ELR after R0 resection presents adverse effects on OS and SAR than those with LLR, and TLR could serve as a promising predictor for OS and SAR.

Clinical Associations of Preoperative and Postoperative Serum CEA and Lung Cancer Outcome.

Background: Serum carcinoembryonic antigen (CEA), a classic tumour marker, is widely used in lung cancer in clinical practice. Nevertheless, few studies have elucidated the influence of dynamic changes in CEA in the perioperative phases, as a prognostic indicator, on lung cancer prognosis. Methods: This retrospective cohort analysis included consecutive patients with stage I-III lung cancer who underwent curative resection between December 2010 and December 2014. The patients were grouped into three cohorts: group A included patients with normal preoperative CEA, group B included patients with elevated preoperative CEA but normal postoperative CEA, and group C included patients with elevated preoperative and postoperative CEA. Five-year overall survival (OS) was estimated by Kaplan-Meier analysis (log-rank test). Multivariate analyses were performed with Cox proportional hazard regression. Results: A total of 1662 patients with stage I-III lung cancer were enrolled in our study. Patients with normal preoperative CEA had 15.9 and 20.1% better 3- and 5-year OS rates than the cohort with elevated preoperative CEA (p < 0.001). Furthermore, group C had 36.0 and 26.6% lower 5-year OS rates (n = 74, 32.4%) than group A (n = 1188, 68.4%) and group B (n = 139, 59.0%) (p < 0.001). Group B had poorer OS than group A (p = 0.016). For patients with different pathological TNM stages, subgroup analyses showed that group C had the shortest OS in stages I and II (p < 0.05), and patients with a post-preoperative CEA increment had poorer OS than those without an increment (p = 0.029). Multivariate analyses suggested that group C (HR = 2.0, 95% CI, 1.5–2.7, p < 0.001) rather than the group with normalized postoperative CEA (HR = 1.2, 95% CI, 0.9–1.5, p = 0.270) was an independent prognostic factor. In subgroup analysis of adenocarcinoma (ADC), survival analyses suggested that group C predicted a worse prognosis. Multivariate analysis of ADC indicated that group C was an independent adverse prognostic factor (HR = 1.9, 95% CI, 1.4–2.7, p < 0.001). Conclusions: Combined elevated preoperative and postoperative CEA is an independent adverse prognostic factor for stage I-III lung adenocarcinoma. Additionally, routine perioperative detection of serum CEA can yield valuable prognostic information for patients after lung cancer surgery.

Overexpression of serum lncRNA-ABHD11-AS1 as poor prognosis of patients with papillary thyroid carcinoma

This paper was aimed at exploring the correlation of long non-coding RNA (lncRNA)-ABHD11 Antisense RNA1 (ABHD11-AS1) with the poor prognosis of patients with papillary thyroid carcinoma (PTC) and at investigating its effects on the survival of PTC cells. Serum was respectively collected from 64 PTC patients who were admitted to our hospital (PTC group) and from 50 healthy controls who underwent physical examinations (HC group) both from April 2011 to April 2015. The expression levels of ABHD11-AS1 in the serum were detected, and the values of it for diagnosis and prognosis (5-year follow-ups) were analyzed. The knockdown and overexpression models of ABHD11-AS1 in were constructed to explore the effects of the models on their proliferation, cycles and apoptosis. According to the data, the expression levels of serum ABHD11-AS1 in the PTC patients were remarkably higher than those in the healthy controls, and the area under the curve (AUC) for distinguishing the patients from the controls was 0.920. In the analysis of prognosis, the levels in patients with a poor prognosis were remarkably higher than those in patients with a good prognosis. According to the curves of overall survival rates (OSRs), the high levels of ABHD11-AS1 were remarkably correlated with the poor prognosis (a lower 5-year OSR). COX analysis showed that TNM staging, lymph node metastasis and ABHD11-AS1 were the independent prognostic factors of PTC patients. In the cell experiments, knocking down ABHD11-AS1 remarkably inhibited PTC cells from proliferation, arrested them in G0/G1 phase, and induced their apoptosis, negatively affecting their survival indices. Overexpressing this RNA had positive effects on the survival indices.Taken together, high levels of serum ABHD11-AS1 are related to the poor prognosis of PTC patients, and knocking down its expression can inhibit the survival of PTC cells.

A Prognostic Model Based on Clinicopathological Features and Inflammation- and Nutrition-Related Indicators Predicts Overall Survival in Surgical Patients With Tongue Squamous Cell Carcinoma.

Objectives: It is reported that inflammation- and nutrition-related indicators have a prognostic impact on multiple cancers. Here we aimed to identify a prognostic nomogram model for prediction of overall survival (OS) in surgical patients with tongue squamous cell carcinoma (TSCC). Methods: The retrospective data of 172 TSCC patients were charted from the Cancer Hospital of Shantou University Medical College between 2008 and 2019. A Cox regression analysis was performed to determine prognostic factors to establish a nomogram and predict OS. The predictive accuracy of the model was analyzed by the calibration curves and the concordance index (C-index). The difference of OS was analyzed by Kaplan–Meier survival analysis. Results: Multivariate analysis showed age, tumor node metastasis (TNM) stage, red blood cell, platelets, and platelet-to-lymphocyte ratio were independent prognostic factors for OS, which were used to build the prognostic nomogram model. The C-index of the model for OS was 0.794 (95% CI = 0.729-0.860), which was higher than that of TNM stage 0.685 (95% CI = 0.605-0.765). In addition, decision curve analysis also showed the nomogram model had improved predictive accuracy and discriminatory performance for OS, compared to the TNM stage. According to the prognostic model risk score, patients in the high-risk subgroup had a lower 5-year OS rate than that in a low-risk subgroup (23% vs 49%, P < .0001). Conclusions: The nomogram model based on clinicopathological features inflammation- and nutrition-related indicators represents a promising tool that might complement the TNM stage in the prognosis of TSCC.

Time to Local Recurrence as a Predictor of Survival in Patients With Soft Tissue Sarcoma of the Extremity and Abdominothoracic Wall.

ObjectiveThe purpose of this retrospective study was to identify the prognostic significance of time to local recurrence (TLR) with regard to overall survival (OS) and survival after local recurrence (SAR) in patients with soft tissue sarcoma (STS) of the extremity and abdominothoracic wall.MethodsWe identified 477 patients who underwent R0 resection for localized STS of the extremity and abdominothoracic wall, from January 1995 to December 2016, of whom 190 patients developed local recurrence as their first recurrent event. Based on TLR, patients were divided into two groups: early local recurrence (ELR, <12 months) and late local recurrence (LLR, ≥12 months). The Kaplan–Meier method and Cox regression analysis were used to estimate the OS and SAR, and to identify factors associated with patient outcomes.ResultsThe median follow-up time for the entire cohort was 118.4 months, and was 118.5 months for the 190 patients who developed local recurrence. Deep tumor location (HR 1.73, 95% CI 1.27–2.37, P = 0.001) and tumor grade ≥2 (G2 vs. G1: HR 1.75, 95% CI 1.21–2.53, G3 vs. G1: HR 2.57, 95% CI 1.66–3.98, P < 0.001) were associated with a higher rate of local recurrence. There were 99 patients in the ELR group and 91 in the LLR group, with a median TLR of 10.8 months for the entire cohort. Patients from the ELR group had a shorter OS and a lower 5-year OS rate than the LLR group. Univariate and multivariate analyses demonstrated TLR as an independent prognostic factor for SAR and OS, in addition to tumor grade. Also, surgical treatment and absence of metastasis after local recurrence were associated with longer SAR.ConclusionsIn patients with STS of the extremity and abdominothoracic wall, ELR after R0 resection indicated a worse prognosis than those with LLR, and TLR can be considered an independent prognostic factor for OS and SAR. Furthermore, local recurrence was significantly influenced by the depth and the histopathological grading of the primary tumor, and reoperation after local recurrence could improve survival, which means salvage surgery may still be the preferred treatment when there are surgical indications after recurrence.

Clinical analysis of newly diagnosed acute lymphoblastic leukemia with 11q23/MLL gene rearrangement

To analyze the laboratory and clinical features and prognosis of patients with acute lymphoblastic leukemia (ALL) and 11q23/MLL gene rearrangement. A total of 725 patients with ALL were enrolled. The 11q23/MLL gene rearrangement and its partner genes were detected. The clinical and laboratory features and prognosis of patients with MLL gene rearrangement were analyzed. MLL gene rearrangement was detected in 42 cases (5.8%) of the patients, with the dominant immunophenotype being pro-B-ALL. Among the partner genes, the MLL/AF4 was the most common. Compared with the non-MLL/AF4 group, the MLL/AF4 group had higher white blood cell and immature cell counts. No significant difference was found in complete remission and 1-year overall survival (OS) rates between the two groups (P> 0.05). Compared with the non-MLL/AF4 group, the MLL/AF4 group had a higher recurrence rate (P<0.05) and a lower 3-year OS rate (P<0.05). Compared with the untransplantation group, the transplantation group had higher 2-year OS and progress free survival rates (P<0.05). Multivariate analysis suggested age ≤1 year, MLL/AF4 positive, early recurrence, and allogeneic hematopoietic stem cell transplant (Allo-HSCT) to be independent factors which can influence the survival of ALL patients with 11q23/MLL rearrangement (P<0.05). MLL/AF4 is the most common partner gene for 11q23/MLL gene rearrangement. This type of leukemia is mainly pro-B-ALL. Although conventional chemotherapy can achieve certain rate of remission, it is easy to relapse and the prognosis is very poor. Allo-HSCT may improve the prognosis.

Comparison between robot-assisted radical hysterectomy and abdominal radical hysterectomy for cervical cancer: A multicentre retrospective study

ObjectiveTo compare 3-year overall survival (OS) and disease-free survival (DFS) rates of robot-assisted radical hysterectomy (RRH) and abdominal radical hysterectomy (ARH) for cervical cancer. MethodsWe retrospectively compared the oncological outcomes of 10,314 cervical cancer patients who received RRH (n = 1048) or ARH (n = 9266) and whose stages were IA1 with lymphovascular space invasion (LVSI)-IIA2. Kaplan-Meier survival analysis and log-rank tests were used to compare the 3-year OS and DFS rates between the RRH and ARH groups. Cox proportional hazards model and propensity score matching was used to estimate the surgical approach-specific survival. ResultsRRH and ARH showed similar 3-year OS and DFS rates (93.5% vs. 94.1%, p = 0.486; 90.0% vs. 90.4%, p = 0.302). RRH was not associated with a lower 3-year OS rate by the multivariable analysis (HR 1.23, 95% CI 0.89–1.70, p = 0.206), but it was associated with a lower 3-year DFS rate (HR 1.20, 95% CI 1.09–1.52, p = 0.035). After propensity score matching, patients who underwent RRH had decreased 3-year OS and DFS rates compared to those who underwent ARH (94.4% vs. 97.8%, p = 0.002; 91.1% vs. 95.4%, p = 0.001), and RRH was associated with lower 3-year OS and DFS rates. Among patients with stage IB1 and tumor size <2 cm, RRH was not associated with decreased 3-year OS and DFS rates (HR1.688, 95% CI 0.423–6.734, p = 0.458; HR1.267, 95%CI 0.518–3.098, p = 0.604). ConclusionsOverall, RRH was associated with worse 3-year oncological outcomes than ARH in patients with FIGO stage IA1 with LVSI- IIA2 cervical cancer. However, RRH showed similar 3-year oncological outcomes with ARH among those with stage IB1 and tumor size <2 cm.

Maximal standard uptake values of 18F-fluoro-2-deoxy-D-glucose positron emission tomography compared with Epstein-Barr virus DNA as prognostic indicators in de novo metastatic nasopharyngeal carcinoma patients

BackgroundThis study aimed to evaluate the prognostic value of maximal standard uptake values (SUVmax) of 18F-fluoro-2-deoxy-D-glucose positron emission tomography (PET) comparing with Epstein-Barr virus (EBV) DNA levels in de novo metastatic nasopharyngeal carcinoma (NPC) patients.MethodsFrom December 2006 to December 2016, 253 de novo metastatic NPC patients assessed by PET/ computed tomography were involved in current study. SUVmax-T, SUVmax-N, and SUVmax-M referred to the SUVmax at the primary tumor, cervical lymph nodes, and metastatic lesions respectively. Overall survival (OS) was the primary endpoint.ResultPatients who died during the follow-up had significantly higher SUVmax-N, SUVmax-M, and EBV DNA level than those in the patients who were alive. SUVmax-N and SUVmax-M were positively correlated with EBV DNA level. The cut-off values of SUVmax-T, SUVmax-N, SUVmax-M, and EBV DNA were 17.0, 12.7, and 6.9, and 13,800 copies/mL respectively, which were determined by receiver operating characteristic (ROC) curve analysis. Patients with elevated SUVmax-N, SUVmax-M, and EBV DNA levels had a lower 3-year OS rate. In multivariate analysis, the independent prognostic factors of OS included EBV DNA, metastatic site, and locoregional radiotherapy application, while SUVmax was not an independent prognostic factor.ConclusionIn de novo metastatic NPC patients, higher SUVmax-N and SUVmax-M were associated with worse prognosis. However, the predictive ability of SUVmax-N and SUVmax-M was poorer than that of EBV DNA.

Prognostic significance of combining immunohistochemical markers for cancer-associated fibroblasts in lung adenocarcinoma tissue.

Cancer-associated fibroblasts (CAFs), activated fibroblasts in a cancer microenvironment, exert various effects upon carcinoma cells including lung adenocarcinoma cells. Various markers identifying CAFs have been proposed, but the correlations among these markers proposed and their clinicopathological significance have remained largely unknown. Therefore, in this study, we immunohistochemically evaluated the expression of alpha-smooth muscle actin (α-SMA), podoplanin, and periostin among these proposed markers in 92 cases of lung adenocarcinoma. These three markers were weakly correlated, but the relative abundance of α-SMA was significantly associated with high Ki-67 labelling index (LI), lymph node metastasis, and low 5-year overall survival (OS) rate of the patients. That of podoplanin was significantly associated with high pT and Ki-67 LI, distant metastasis, and low 5-year OS rate and that of periostin with high pT and Ki-67 LI. We then tentatively subclassified these cases into four groups according to high or low status of each of paired markers: α-SMA/podoplanin, α-SMA/periostin, and periostin/podoplanin. The α-SMA high/podoplanin high group was associated with the lowest survival rate (53.3%) among the four groups with significance. However, there were no significant differences in overall survival when the patients were classified according to the combinations of α-SMA/periostin or periostin/podoplanin. Results of our study firstly revealed the heterogeneity of CAFs in human lung adenocarcinoma tissue, and the analysis employing multiple markers of CAFs is generally required to study the clinical significance of CAFs in clinical materials.

CD133 expression correlates with clinicopathologic features and poor prognosis of colorectal cancer patients: An updated meta-analysis of 37 studies.

Background:CD133 has been identified as a putative cancer stem cell marker in colorectal cancer (CRC). However, the clinicopathological and prognostic significance of CD133 in CRC patients remains controversial. Thus, we conducted a meta-analysis to quantitatively evaluate the above issues.Methods:We collected a comprehensive literature search from PubMed, Web of Science, and Embase database up to September 20, 2016 examining CD133 and clinical features of colorectal cancer patients. We used the odds ratio (OR) with 95% confidence interval (CI) to estimate the effects by overall and stratified analysis.Results:The overall result of our meta-analysis indicated that CD133 expression was positively correlated with T category, distant metastasis, lymphatic invasion, and vascular invasion. Moreover, patients with higher CD133 expression had a poorer overall survival (OS) (HR=2.01, P < .001) and a lower 5-year OS rate (OR = 3.26, P < .001) than those with lower expression. Disease-free survival (DFS) and 5-year DFS rate were similar with the above results. Though the correlation between CD133 expression with the clinical characteristic was not positive in some ways when we analyzed the different subgroup. The prognostic value of CD133 expression for 5-year OS rate of CRC patients was noticeable in spite of different patients’ region, multiple antibodies used in studies, various cut-off values of CD133 expression, and adjuvant therapy situation of patients.Conclusion:CD133 is a useful predictive or prognostic biomarker for CRC in clinical assessment and may serve as a potential therapeutic target for CRC.

The impact of the neutrophil:lymphocyte ratio in response and survival of patients with de novo diffuse large B-cell lymphoma

The neutrophil:lymphocyte ratio (NLR) has emerged as prognostic in patients with hematological malignancies. We aimed at evaluating the NLR as predictive for complete response (CR) and prognostic for progression-free (PFS) and overall survival (OS) in a study cohort of 121 Peruvian patients with diffuse large B-cell lymphoma (DLCBL) treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP). Patients with an NLR ≥6 (n = 28) were more likely to have a performance status ECOG ≥2 (74% vs. 23%; p < 0.001). NLR ≥6 was associated with lower CR rate to R-CHOP (46% vs. 74%; p = 0.02) and there was a trend towards significance in multivariate regression analyses (OR 0.36, 95% CI 0.11–1.00; p = 0.05). Patients with NLR ≥6 had lower 5-year PFS rate (39% vs. 72%; p < 0.001) and lower 5-year OS rate (46% vs. 75%; p = 0.001) than patients with NLR <6 and was an independent adverse factor for PFS (HR 2.43, 95% CI 1.21–4.87; p = 0.01) and OS (HR 2.68, 95% CI 1.31–5.47; p = 0.007) in multivariate Cox regression analyses. NLR ≥6 was prognostic of PFS and OS after adjusting for the International Prognostic Index and the NCCN-IPI scores. In conclusion, the NLR could add predictive and prognostic value to well established prognostic tools in DLBCL.

Long-term follow-up of neuroblastoma in children less than 18 months of age

Objective: To assess the clinical features and long-term outcomes of neuroblastoma (NB) in children less than 18 months of age, so as to provide evidence for further improvement of treatment. Method: Clinical data(sex, age, stage, risk group, treatment response, follow-up, etc.) of 155 NB patients under age of 18 months from June 2000 to December 2015 in Shanghai Children's Medical Center were analyzed retrospectively. The clinical features were summarized and the long-term follow-up results were evaluated. The overall survival (OS) and event-free survival (EFS) were analyzed by using Kaplan-Meier method. Factors including age, stage, risk group, bone marrow and bone metastasis, N-MYC status and dehydrogenase(LDH) level were analyzed by Log-Rank test. Result: Totally 155 eligible patients (96 males, 59 females) were included. The median age of disease onset was 7 months (11 days to 18 months). There were 31 cases of stage 1, 19 cases of stage 2, 45 cases of stage 3, 38 cases of stage 4 and 21 cases of stage 4S. The median follow-up time was 36 months (range 4 to 189 months), the 3-year and 5-year EFS rate were 89.6% and 85.2% respectively and the 3-year and 5-year OS rate were 96.2% and 94.1%, respectively. A total of 15 recurrent or progressed cases were observed. The median time to first recurrence was 11 months (range 3 to 39 months), 6 cases eventually died. Second malignancy occurred in one patient. The patients who had relapsed disease within 12 months from initial diagnosis have much lower 3-year OS rate than those in whom the disease recurred 12 months later (25.7% vs. 83.3%, P=0.020). Although the number of chemotherapy courses in median-high risk group reduced from 8.6 courses to 7.5 courses after the revision in 2008, the survival rate showed no significant difference between before and after (5-year EFS 74.4% vs. 84.3%, 5-year OS 89.0% vs. 92.9%, both P>0.05). In patients with stage 1 and stage 2, the 3-year EFS of 34 cases with surgery alone and 16 cases accepted chemotherapy were both 100%. Age at diagnosis, stage, risk group, MYCN status, LDH level, bone marrow involvement and bone infiltration had significant impacts on prognosis(all P<0.05). Conclusion: Satisfactory outcomes could be achieved in neuroblastoma in children aged within 18 months; the prognosis was better in children at age less than 12 months compared with 12-18 months. MYCN amplification, LDH more than 5 times upper limit of normal range, bone marrow and bone infiltration were associated with worse prognosis.Excellent survival rates could be achieved in children with stage 1 and 2 disease within 18 month's old accepted surgery alone, chemotherapy or radiotherapy could be avoided in these patients so as to reduce long-term adverse reactions.

Role of radiotherapy in patients with stage I-II diffuse large B-cell lymphoma of waldeyer’s ring in remission after chemotherapy

Objective To investigate the impacts of adjuvant radiotherapy on the prognosis of patients with stage Ⅰ-Ⅱ diffuse large B cell lymphoma of Waldeyer’s ring (WR-DLBCL) who achieved complete remission (CR) after chemotherapy. Methods Clinical data were collected from 130 patients with stage Ⅰ-Ⅱ WR-DLBCL who were admitted to our hospital from 2005 and 2013. All the patients achieved CR after at least two cycles of cyclophosphamide, doxorubicin/epirubicin, vincristine, and prednisone (CHOP)-based chemotherapy or rituximab plus CHOP (R-CHOP)-based chemotherapy. In the 130 patients, 43 received R-CHOP (including 25 patients undergoing radiotherapy) and 87 CHOP (including 76 patients undergoing radiotherapy); 29 received chemotherapy alone and 101 chemoradiotherapy. The survival rates were calculated by the Kaplan-Meier method and analyzed by the log-rank test. Univariate and multivariate prognostic analyses were made by the log-rank test and the Cox model, respectively. Results In all patients, the 5-year sample size was 101. The univariate analysis showed that patients with an Eastern Cooperative Oncology Group (ECOG) score of 0 had significantly higher 5-year overall survival (OS) and disease-free survival (DFS) rates than those with an ECOG score of 1(95.6% vs. 80.1%, P=0.000; 95.7% vs. 75.4%, P=0.029). Patients treated with chemotherapy alone had significantly lower 5-year OS and DFS rates than those treated with chemoradiotherapy (77.1% vs. 91.7%, P=0.048; 77% vs. 87.4%, P=0.037). The multivariate analysis by the Cox model showed that ECOG score was a prognostic factor for both OS and DFS (P=0.047, 0.003). Adjuvant radiotherapy was related to improved DFS rather than OS (P=0.039, 0.133). Conclusions Stage Ⅰ-Ⅱ WR-DLBCL patients with low ECOG scores have better prognosis than those with high ECOG scores. Patients with CR after chemotherapy may benefit from adjuvant radiotherapy. The conclusions need to be further confirmed by prospective randomized controlled trials.

Primary site and regional lymph node involvement are independent prognostic factors for early-stage extranodal nasal-type natural killer/T cell lymphoma.

BackgroundNasal-type extranodal natural killer/T-cell lymphoma (ENKTCL) originates primarily in the nasal cavity or extra-nasal sites within the upper aerodigestive tract. However, it is unclear whether the primary site can serve as an independent prognostic factor or whether the varying clinical outcomes observed with different primary sites can be attributed merely to their propensities of regional lymph node involvement. The aim of this study was to investigate the prognostic implications of the primary site and regional lymph node involvement in patients with early-stage nasal-type ENKTCL.MethodsTo develop a nomogram, we reviewed the clinical data of 215 consecutively diagnosed patients with early-stage nasal-type ENKTCL who were treated in Sun Yat-sen University Cancer Center with chemotherapy and radiotherapy between 2000 and 2011. The predictive accuracy and discriminative ability of the nomogram were determined using a concordance index (C-index) and calibration curve.ResultsThe 5-year overall survival (OS) and progression-free survival (PFS) rates of patients with nasal ENKTCL were higher than those of patients with extra-nasal ENKTCL (OS: 68.2% vs. 46.0%, P = 0.030; PFS: 53.4% vs. 26.6%, P = 0.010). The 5-year OS and PFS rates of patients with Ann Arbor stage IE ENKTCL were higher than those of patients with Ann Arbor stage IIE ENKTCL (OS: 66.3% vs. 59.2%, P = 0.003; PFS: 51.4% vs. 40.3%, P = 0.009). Multivariate analysis showed that age >60 years, ECOG performance status score ≥2, elevated lactate dehydrogenase (LDH) level, extra-nasal primary site, and regional lymph node involvement were significantly associated with lower 5-year OS rate; age >60 years, elevated LDH level, extra-nasal primary site, and regional lymph node involvement were significantly associated with lower 5-year PFS rate. The nomogram included the primary site and regional lymph node involvement based on multivariate analysis. The calibration curve showed good agreement between the predicted and actual 5-year OS and PFS rates, and the C-indexes of the nomogram for the OS and PFS rates were 0.697 and 0.634, respectively.ConclusionsThe primary site and regional lymph node involvement are independent prognostic factors for early-stage ENKTCL treated with chemotherapy followed by definitive radiotherapy.
