The Clinical Characteristics, Risk Classification System, and Web-Based Nomogram for Primary Spinal Ewing Sarcoma: A Large Population-Based Cohort Study.

The goal of this study was to determine the clinical characteristics of patients with primary spinal Ewing sarcoma (PSES) and to create a prognostic nomogram. Clinical information related to patients diagnosed with PSES between 2004 and 2015 was extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Independent prognostic factors were identified using univariate and multivariate Cox analyses to construct nomograms predicting overall survival in patients with PSES. Calibration curves and receiver operating characteristic curves were used to assess the model's prediction accuracy, while decision curve analysis was used to assess the model's clinical utility. The overall number of 314 patients with PSES were screened from the SEER database between 2004 and 2015. Race, chemotherapy, age, and disease stage were found to be independent predictive factors for overall survival in both univariate and multivariate Cox analyses. The training and validation cohorts' calibration curves, receiver operating characteristic curves, and decision curve analysis showed that the nomogram has strong discrimination and clinical value. Furthermore, a new risk classification system has been constructed that can divide all patients into 2 risk groups. Based on a broad population, the research demonstrates statistical evidence for the clinical features and prognostic variables of patients with PSES. The constructed prognostic nomogram provides a more precise prediction of prognosis for PSES patients.

Electronic patient reporting outcomes are a promising predictive factor of prostate cancer patient survival: The Protecty study.

76 Background: The benefits of Electronic Patient Remote Outcomes (e-PRO) for telemonitoring are well established, allowing early detection of illnesses and continuous monitoring of patients. We have previously shown high levels of compliance of use of telemonitoring in daily care. This new PROTECTY study assesses the predictive power of patient health status in the first month of treatment on survival, evaluated with the telemonitoring platform Cureety. Methods: This prospective study was conducted at the Military Hospital Bégin on prostate cancer patients. Patients were allowed to respond to a symptomatology questionnaire based on CTCAE v.5.0, personalized to their pathology and treatment. An algorithm evaluates the health status of the patient based on the reported adverse events, with a classification into 2 different states: Good Health status (A) Poor Health status (B) In case of A, the patient received therapeutic advice to help manage each of the reported adverse events. In case of B, the patient is invited to call the hospital. For the purpose of this analysis, we collected their health status during the first month after initiation of treatment. The primary endpoint was to assess if the first month health status is a predictive factor of progression free-survival (PFS) for prostate cancer patient. The secondary endpoint was to assess if the first month health status is a predictive factor of overall survival (OS) for prostate cancer patient. Results: Sixty-one patients were enrolled between July 1st, 2020 and June 30st, 2021. The median age was 74.0 (range 58.0 – 94.0). 62% presented a metastatic stage, and the most represented cancer was mHSPC with 39,5% among metastatic patients. Overall, 2443 questionnaires were completed by the patients, 4.0% resulted in a health classification in state B. 86,9% of patient were classified in group A the first month. 13,1% of patient were classified in group B the first month. The median follow up was 12.3 months. PFS at 12 months was 89% in A group vs 60% in B group, p=0,17 OS at 12 months was 100% in A group vs 86% in B group, p=0,15. Conclusions: Our study is the first to assess the impact of tolerance treatment on survival. The initial results suggest that e-PRO assessment by the platform could help identify in the early stages the patients that require further health assessment and potential therapeutic changes. While further follow-up of more patients will be required, our study highlights the importance of e-PRO in cancer patient care.

Survival Outcomes of Patients With Epidermal Growth Factor Receptor Mutations in Non-Small Cell Lung Cancer With Leptomeningeal Metastasis.

BackgroundLeptomeningeal metastasis (LM) is a commonly observed complication in patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC). This study aimed to investigate the gene mutations, treatment strategies, and clinical outcomes in patients with LM.MethodsWe retrospectively analyzed the clinical and survival outcomes of 53 patients with EGFR-mutated NSCLC with LM.ResultsThe median overall survival after LM diagnosis was 13.0 months, ranging from 0.5 to 42.0 months (95% CI = 9.067–16.933), with 64.2% maturity. Patients who received osimertinib after developing LM (n = 35) had a significantly higher rate of LM disease control (p = 0.008) and significantly longer overall survival (15.0 versus 6.0 months; hazard ratio (HR), 2.4292; 95% CI, 1.234–4.779; p = 0.045) than those who received previous generations of EGFR tyrosine kinase inhibitors (TKIs) or other localized therapies (n = 6). Logistic regression analysis showed that LM disease control status was a positive predictive factor for overall survival after developing LM (p < 0.001, odds ratio = 10.797, 95% CI = 4.102–28.419).ConclusionsOur study provides real-world clinical evidence that patients with EGFR-mutated NSCLC diagnosed with LM who developed LM had better clinical outcomes with osimertinib therapy. Our findings also suggest that LM disease control is the most effective strategy to prolong the overall survival outcomes of these patients.

Bevacizumab in metastatic colorectal cancer in a real-life setting - toxicity profile, survival outcomes, and impact of tumor sidedness.

IntroductionTargeting angiogenesis in metastatic colorectal cancer (mCRC) using bevacizumab is a standard of care. The addition of this targeted biological agent to first-line infusional fluoropyrimidine-based chemotherapy was associated with superior overall survival (OS) in several randomized and controlled studies for CRC patients in the metastatic setting. However, access to this therapy in countries with limited resources is challenging. In Morocco, bevacizumab was introduced for this indication after considerable efforts of the Ministry of Health and Lalla Salma Foundation to support cancer patients with a limited income. In this report, the real-world efficacy and safety of the combination of bevacizumab with chemotherapy in mCRC are reported based on a retrospective cohort in Eastern Morocco.Material and methodsThe archives of the medical records of 98 mCRC patients treated with first-line bevacizumab at the Hassan II Regional Cancer Center (Oujda, Morocco) were sampled from 1st January 2014 to 31st December 2019 and analyzed using descriptive statistics, Kaplan-Meier estimation, and a multivariable Cox regression model for a time-to-event study.ResultsThe toxicity profile was dominated by grade I–II proteinuria (10%), bleeding events (10%), thromboembolic events (9%), grade I–III hypertension (3%), and other rare events such as delayed healing of the stoma, scar dehiscence, intestinal perforation, and heart failure deterioration. In terms of survival, median OS and progression-free survival in the whole cohort were 22 and 13 months respectively. Patients who benefited from a metastasectomy after bevacizumab treatment had 31 months of median OS as compared to 14 months in the matched cohort with non-resectable liver metastasis. Notably, we demonstrated that tumor sidedness is a predictive factor of OS [hazard ratio (HR) = 2.452; 95% CI: 1.434–4.191, p = 0.001]. Moreover, the median OS for patients who received between 10 and 20 or more than 20 bevacizumab administrations was 24 and 33 months respectively as compared to those who received less than 10 cures (17 months) (log rank p < 0.0001). These markedly improved outcomes were also confirmed in multivariate Cox regression. A highly significant association of bevacizumab use and OS was found after adjusting for covariates (HR = 0.518, 95% CI: 0.374–0.717; p < 0.0001).ConclusionsThe current study confirmed the important place of this therapeutic strategy in mCRC. Additional studies with prospective enrollment are awaited to validate these findings.

Does the Overall Survival of the Resectable Periampullary Carcinomas Correlate with High Expression of p53 and ki67?

Introduction: Periampullary carcinomas represent a group of tumors that develop in a complex area, implying different anatomical structures. The most common histological type of periampullary carcinomas is the adenocarcinoma. The pancreatic type of periampullary adenocarcinomas has the worst prognosis. Immunohistochemical markers, such as ki-67 and p53, can be used in predicting survival. Material and method: we selected the patients with periampullary adenocarcinomas, intestinal or biliopancreatic type, with resectable tumors, and we performed immunohistochemical stains for ki-67 and p53 markers. The overall survival was analyzed according to the expression of immunohistochemical markers, TNM staging, tumor grade and perineural invasion. Results: Sixty-seven patients were included in the study. The median overall survival for the whole cohort was 12 months, with a 2-year survival rate of 25%. High rate of tumor proliferation (ki67 more than 80%) was significantly associated with shorter overall survival (median survival 3 months compared with 17 months for the group with ki67 index less than 80%). A high expression of p53 protein has been associated with low overall survival. The low survival was associated with poorly differentiated tumor grade and lymph node status. Conclusion: Both immunohistochemical expression of ki67 and p53 can be used as prognostic and predictive factors for overall survival of patients with resectable periampullary adenocarcinomas.

An assessment of predictive factors for overall survival in glioblastoma – MGMT methylation is solely important for younger patients

An assessment of predictive factors for overall survival in glioblastoma – MGMT methylation is solely important for younger patients

Prospective multicentre analysis of the therapeutic approach and prognostic factors determining overall survival in elderly patients with non-small-cell lung carcinoma treated with curative intent.

Objective:To analyse patterns of treatment with curative intent commonly used in elderly patients with locally advanced non-small-cell lung carcinoma (NSCLC) and predictive factors of overall survival in routine clinical practice.Methods:This multicentre prospective study included consecutive patients aged ≥65 years old diagnosed with NSCLC between February 2014 and January 2018. Inclusion criteria: age ≥65 years, stage IIIA/IIIB NSCLC. Treatment decisions were taken by a multidisciplinary committee. Kaplan-Meier curves and log-rank test were used to identify which clinical/treatment-associated variables, or pre-treatment quality of life (QOL) considering EORTC QLQ-C30 (and LC13 module) were predictive of overall survival.Results:A total of 139 patients were recruited. Median follow-up was 9.9 months (1.18-57.36 months) with a median survival of 14 months (range 11-17 months). In the group>75-year-old patients, the committee recommended chemotherapy and sequential radiotherapy (55.6%) or radiotherapy alone (22.2%), rather than surgery (3.7%) or concomitant radiochemotherapy (16.5%). However, in 65- to 75-year-old patients, surgery and concomitant radiochemotherapy were recommended in half of cases (p=0.003). Regarding multivariate analysis, the risk of death was higher in patients with pre-existing heart disease (p=0.002), low score for physical functioning (p=0.0001), symptoms of dysphagia (p=0,01), chest pain (p=0.001), and those not undergoing surgical treatment (p=0.024).ConclusionsPatients >75 years received more conservative treatments. Surgery improved survival and should be carefully considered, regardless of patient age. Comorbidities and poor baseline QOL are predictive of shorter survival.Advances in knowledge:Measuring these parameters before treatment may help us to define a population of frail patients with a poorer prognosis to facilitate decision making in clinical practice.

Impact of preoperative endoscopy for predicting treatment response and prognosis in patients with gastric cancer after neoadjuvant chemotherapy.

Background and study aims Response evaluation criteria in solid tumors (RECIST) have been the gold standard to preoperatively predict treatment response and prognosis in patients with gastric cancer (GC) after neoadjuvant chemotherapy (NAC); however, methods for patients without evaluable lesions by RECIST are not yet confirmed. The aim of this study was to assess the utility of preoperative endoscopy for predicting treatment response and prognosis in patients with GC after NAC. Patients and methods This retrospective study included 105 patients with initially resectable GC who underwent NAC followed by surgical treatment. Preoperative factors for predicting treatment response and survival outcomes were analyzed. Results The number of patients classified as responders using preoperative endoscopic assessment, RECIST, and postoperative pathological evaluation were 25 (23.8 %), 28 (26.7 %), and 18 (17.1 %), respectively. Forty-three patients (41 %) were classified as non-targeted disease only, and their treatment responses were not evaluable by RECIST. Multivariate analysis identified endoscopic response as an independent preoperative factor to predict postoperative histological treatment response (odds ratio = 4.556, 95 % CI = 1.169–17.746, P = 0.029). Endoscopic treatment response was the only independent preoperative predictive factor for overall survival (OS) (hazard ratio = 0.419, 95 % confidence interval (CI) = 0.206–0.849, P = 0.016). Further, endoscopic treatment response was available for 33 patients (76.7 %) with non-targeted disease only, which showed significantly different OS between endoscopic responders (80.0 %) and non-responders (43.5 %) ( P = 0.025). Conclusions Endoscopic evaluation was an independent preoperative factor to predict treatment response and prognosis in patients with GC after NAC. Endoscopic assessment may be especially valuable for patients who could not be assessed by RECIST.

Circulating tumor cells in blood as a prognostic biomarker in tongue squamous cell carcinoma

The studyaimed to evaluate the role of circulating tumor cells (CTCs) as a prognostic biomarker of tongue squamous cell carcinoma (TSCC). CTC levels in the peripheral blood of 50 patients with TSCC at baseline (i.e., before treatment) and of 8 healthy donors were determined using the NanoVelcro system. The relationship between CTC levels and clinicopathologic parameters and clinical outcomes such as recurrence, metastasis, and death during follow-up (mean 17 months) was analyzed. CTCs levels were closely correlated with TSCC clinical staging (P = .002), N staging (P = .007), and progression status (P = .002) in TSCC patients. Receiver operating characteristic (ROC) analysis revealed that the count of CTC ≥4 (area under curve: 0.832 [95% confidence interval 0.695-0.950]; sensitivity: 0.83; specificity: 0.75; P < .001) was a better prognostic marker than TNM stage (area under curve: 0.692 [0.536-0.848]; sensitivity: 0.83; specificity: 0.55; P = .023). In addition, univariate and multivariate analysis showed that the CTC was an important and independent predictive factor for overall survival and disease-free survival (P < .001). CTC was an independent prognostic indicator in patients with TSCC. CTC may be used as an auxiliary parameter to predict the prognosis of TSCC.

A novel staging system and clinical predictive nomogram for more accurate staging and prognosis of malignant pancreatic intraductal papillary mucinous neoplasms: a population-based study

BackgroundThe current guidelines of the American Joint Committee on Cancer (AJCC) for the staging of exocrine pancreatic tumors seem inapplicable to malignant pancreatic intraductal papillary mucinous neoplasms (IPMN). Therefore, we aimed to improve the accuracy of clinical staging and prognosis for malignant IPMN by modifiing current AJCC system.MethodsWe extracted data of 2001 patients with malignant IPMN from the Surveillance, Epidemiology, and End Results database between 2000 and 2016. Of these, 1401 patients were assigned to the primary cohort and 600 patients to the validation cohort.ResultsIn Kaplan–Meier analysis of the primary cohort, the current AJCC guidelines were unable to distinguish between certain tumor substages (IA and IB in the 7th, IB and IIA in the 8th). The modified system that we regrouped based on the median overall survival and hazard ratios, was superior in tumor stage classifications. Age > 70 years, tumors located in the body or tail, high-grade differentiated tumors, surgery, chemotherapy, and tumor, lymph node, and metastasis (TNM) stage were identified as independent predictive factors for overall survival. Compared to that of TNM-based systems, the concordance index of the clinical predictive nomogram significantly improved (0.819; 95% confidence interval, 0.805–0.833), with excellent area under the receiver operating characteristic curves (1-, 3-, and 5-year: 0.881, 0.889, and 0.879, respectively). The calibration curves also showed good agreement between prediction and actual observation. The analysis of treatment modalities revealed that surgery resulted in better survival for all resectable malignant IPMN. The analysis of chemotherapy data reveals its potential in improving the prognosis of treatment for patients with locally advanced or distant metastases.ConclusionsOur modified staging system improves the distinction of tumor stages. The nomogram was a more accurate and clinically reliable tool for prognosis prediction of patients with malignant IPMN.

Prognosis of patients operated on for renal cell carcinoma and tumor venous thrombosis: experience of the Urology Clinics, N.N. Blokhin National Medical Research Center of Oncology

Objective: to identify independent risk factors affecting survival of patients with renal cell carcinoma (RCC) and tumor venous thrombosis who have undergone nephrectomy and thrombectomy.Materials and methods. This study included 768 patients with RCC complicated by tumor venous thrombosis who have undergone nephrectomy and thrombectomy. Median age was 58 years (range: 16-82 years); the male to female ratio was 2.3:1. The symptoms of tumor venous thrombosis were identified in 232 patients (30.2 %); laboratory abnormalities at baseline were observed in 456 patients (59.3 %). Grade I and II tumor thrombosis was diagnosed in 456 (59.3 %) and 201 (26.2 %) patients, respectively; grade III and IV thrombosis was found in 171 (22.3 %) and 177 (23.0 %) patients, respectively. One hundred and twenty-nine participants (16.8 %) had infrarenal inferior vena cava thrombosis. Regional metastases were detected in 188 individuals (24.4 %), distant metastases were registered in 274 patients (35.7 %). All patients have undergone surgery: either radical (n = 555; 72.3 %) or cytoreductive (n = 213; 27.7 %). All primary tumors were histologically classified as RCC (G3-4 in 337 cases; 43.9 %). A total of 719 patients (93.6 %) survived the perioperative period; 183 patients with metastasis (23.8 %) received systemic antitumor therapy.Results. The median follow-up was 24 months (range: 1-200 months). The 24-month overall and cancer-specific survival of all patients were 96.9 and 99.7 %, respectively; recurrence-free survival of patients after radical surgery reached 92.9 %. Progression-free survival among those patients who underwent cytoreductive surgery and received first-line therapy/follow-up was 41.7 %. Negative predictive factors of overall survival included hepatomegaly (p = 0.024), ascites (p = 0.033), level IV tumor thrombosis (p &lt;0.0001), infrarenal inferior vena cava thrombosis (p = 0.002), regional metastases (p &lt;0.0001), and cytoreductive surgery (p = 0.012). Depending on the number of risk factors, we have identified 3 prognostic groups: favorable (0 factors), intermediate (1-2 factors), and poor (3-6 factors). Median overall survival differed significantly between the groups and was 128.6 ± 11.8; 40.9 ± 6.7 and 12.3 ± 2.2 months, respectively (p &lt;0.0001 for all).Conclusion. Stratification of patients operated on for RCC and venous tumor thrombosis with their allocation to prognostic groups will ensure the choice of an optimal management strategy.

Correlation between schistosomiasis and CD8+ T cell and stromal PD-L1 as well as the different prognostic role of CD8+ T cell and PD-L1 in schistosomal-associated colorectal cancer and non-schistosomal-associated colorectal cancer

BackgroundThe effect of schistosomiasis on CD8+ T cells and then on PD-L1 expression was unknown, and the utility of CD8+ TILs as a biomarker for schistosomal-associated colorectal cancer (SCRC) rarely has been reported.MethodsThree hundred thirty-eight patients with colorectal cancer (CRC) were enrolled. Immunohistochemical analysis was conducted to evaluate the expression of PD-L1 and the infiltration of CD8+ T cells.ResultsIn the total cohort, the results showed that CD8+ TIL density was positively correlated with tumoral (p = 0.0001) and stromal PD-L1 expression (p = 0.0102). But there were no correlation between schistosomiasis and CD8+ TILs and PD-L1. Furthermore, CD8+ TIL density (p = 0.010), schistosomiasis (p = 0.042) were independent predictive factors for overall survival (OS). Stromal PD-L1 (sPD-L1) was correlated with OS (p = 0.046), but it was not an independent predictor. In patients without schistosomiasis, CD8 + T cells (p = 0.002) and sPD-L1 (p = 0.005) were associated with better OS. In patients with schistosomiasis, CD8 + T cells were independent prognosis factor (p = 0.045).ConclusionsThe study showed that CD8+ TILs was an independent predictive factor for OS in CRC and SCRC patients. The expression of PD-L1 was positively associated with CD8 + TILs density. There were no correlation between schistosomiasis and CD8 + TILs and PD-L1. Stromal PD-L1 but not tPD-L1 was significantly associated with OS, whereas it was not an independent prognostic factor.

Predictive Factors of Overall Survival in Patients with Relapsed AL Amyloidosis Treated with Single Agent Daratumumab

Association of Soluble B7-H4 and Circulating Tumor Cells in Blood of Advanced Epithelial Ovarian Cancer Patients.

IntroductionEpithelial ovarian cancer (EOC) is the deadliest gynecologic malignancy worldwide. Reliable predictive biomarkers are urgently needed to estimate the risk of relapse and to improve treatment management. Soluble immune-checkpoints in EOC are promising molecules serving as prognostic biomarkers accessible via liquid biopsy. We thus, aimed at elucidating the role of sB7-H4 in EOC.Material and MethodsWe analyzed soluble serum B7-H4 (sB7-H4) using ELISA and circulating tumor cells (CTCs) in blood applying the AdnaTest OvarianCancer in 85 patients suffering from advanced EOC. Findings were correlated with clinical parameters as well as survival data.ResultssB7-H4 was detectable in 14.1% patients, CTCs in 32.9% patients and simultaneous presence of CTCs and sB7-H4 was found in 7% patients, respectively. Although no association between sB7-H4 and CTC could be documented, each of them served as independent predictive factors for overall survival (OS).ConclusionsB7-H4 and CTCs are independent prognostic biomarkers for impaired survival in EOC. As they are easily accessible via liquid biopsy, they may be of potential benefit for the prediction of therapy response and survival for EOC patients.

Oncological Safety of Autologous Fat Grafting in Breast Reconstruction after Mastectomy for cancer: A case-control study

The use of autologous fat grafting in the context of breast reconstruction is still a matter of controversy. The objective of this study was to compare the local relapse rate in women who had a fat grafting session in the context of breast reconstruction after breast cancer management, to those who had breast reconstruction without fat grafting. We performed a retrospective, monocentric, case-control study from January 2007 to December 2017 in our hospital. The cases included women who underwent breast reconstruction with autologous fat grafting and controls, undergoing breast reconstruction without fat grafting. We compared survival and local recurrence between the two groups. 412 women were included: 109 (26.5%) in the lipofilling group and 303 women (73.5%) in the "no lipofilling" group. In the overall study population, lipofilling did not appear to be a predictive factor for recurrence, HR=1.39 [0.63 - 3.06], p=0.41; or a predictive factor for overall survival, HR=0.84 [0.23 - 3.02], p=0.79, or for distant metastases, HR=1.10 [0.43 - 2.79], p=0.84. In contrast, in the subgroup of women treated for invasive cancer, the multivariate analysis showed that lipofilling in this context was an independent predictive factor for local recurrence (HR= 5.06 [1.97- 10.6], p=0.04). we found an increased risk of local recurrence after lipofilling in women who were managed for invasive breast cancer. This suggests that special consideration should be given to women who have had invasive breast cancer before lipofilling.

Changes in Neutrophil-to-lymphocyte Ratio Predict Efficacy of Trabectedin for Soft-tissue Sarcoma.

Trabectedin and eribulin are widely used for the treatment of soft-tissue sarcoma (STS). Previously it was shown that the baseline neutrophil-to-lymphocyte ratio (NLR) predicts the efficacy of eribulin for STS. However, prognostic factors for trabectedin on STS have not been identified to date. We conducted a retrospective study of data collected prospectively from 39 patients treated with trabectedin for recurrent or metastatic STS between October 2012 and December 2019. To determine the predictive factors of overall survival (OS) and progression-free survival (PFS), univariate and multivariate analyses were performed. Age ≥40 (HR=0.33, 95% CI=0.15-0.71; p=0.0050) and changes in NLR (ΔNLR) <0.5 (HR=2.40, 95% CI-1.01-5.72; p=0.048) were independent factors predictive of longer OS. In addition, age ≥40 (HR=0.23, 95% CI=0.10-0.52; p<0.001) was an independent predictor of longer PFS. Changes in NLR and age ≥40 years were able to predict the efficacy of trabectedin for STS.

CTLA-4 Synergizes With PD1/PD-L1 in the Inhibitory Tumor Microenvironment of Intrahepatic Cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (ICC) is highly invasive and carries high mortality due to limited therapeutic strategies. In other solid tumors, immune checkpoint inhibitors (ICIs) target cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and programmed death 1 (PD1), and the PD1 ligand PD-L1 has revolutionized treatment and improved outcomes. However, the relationship and clinical significance of CTLA-4 and PD-L1 expression in ICC remains to be addressed. Deciphering CTLA-4 and PD-L1 interactions in ICC enable targeted therapy for this disease. In this study, immunohistochemistry (IHC) was used to detect and quantify CTLA-4, forkhead box protein P3 (FOXP3), and PD-L1 in samples from 290 patients with ICC. The prognostic capabilities of CTLA-4, FOXP3, and PD-L1 expression in ICC were investigated with the Kaplan–Meier method. Independent risk factors related to ICC survival and recurrence were assessed by the Cox proportional hazards models. Here, we identified that CTLA-4+ lymphocyte density was elevated in ICC tumors compared with peritumoral hepatic tissues (P <.001), and patients with a high density of CTLA-4+ tumor-infiltrating lymphocytes (TILsCTLA-4 High) showed a reduced overall survival (OS) rate and increased cumulative recurrence rate compared with patients with TILsCTLA-4 Low (P <.001 and P = .024, respectively). Similarly, patients with high FOXP3+ TILs (TILsFOXP3 High) had poorer prognoses than patients with low FOXP3+ TILs (P = .021, P = .034, respectively), and the density of CTLA-4+ TILs was positively correlated with FOXP3+ TILs (Pearson r = .31, P <.001). Furthermore, patients with high PD-L1 expression in tumors (TumorPD-L1 High) and/or TILsCTLA-4 High presented worse OS and a higher recurrence rate than patients with TILsCTLA-4 LowTumorPD-L1 Low. Moreover, multiple tumors, lymph node metastasis, and high TumorPD-L1/TILsCTLA-4 were independent risk factors of cumulative recurrence and OS for patients after ICC tumor resection. Furthermore, among ICC patients, those with hepatolithiasis had a higher expression of CTLA-4 and worse OS compared with patients with HBV infection or undefined risk factors (P = .018). In conclusion, CTLA-4 is increased in TILs in ICC and has an expression profile distinct from PD1/PD-L1. TumorPD-L1/TILsCTLA-4 is a predictive factor of OS and ICC recurrence, suggesting that combined therapy targeting PD1/PD-L1 and CTLA-4 may be useful in treating patients with ICC.

Blood cell count is not a significant predictor of survival in bladder cancer after radical cystectomy

BackgroundRadical cystectomy (RC) is the gold standard treatment for muscle-invasive bladder carcinoma. A predictive factor is needed for the aggressive approach as it could lead to overtreatment. Elevated blood cell count (BCC) markers are reported to have a significant association with poor outcomes in several types of malignancy. Neutrophil-to-lymphocyte-ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are well-known inexpensive and effective representative markers of inflammatory conditions. This study aimed to determine the BCC as a predictive factor of overall survival (OS) in patients with bladder carcinoma (BC) after RC. MethodsA retrospective cohort study was conducted involving 26 patients who had undergone RC. The demographic characteristics and BCC markers such as hemoglobin (Hb). NLR, PLR and lymphocyte/monocyte ratio (LMR) were collected. The patients were categorized based on the BCC marker value (³ median and &lt; median). Kaplan–Meier survival analysis was done to determine overall survival (OS) on BCC markers. The association between patient demographics and one-year survival was also determined using Mantel-Cox (Log-rank) method. ResultsAmong the 26 patients, the mean age was 55.6 ± 12.9 years. On univariate analysis, none of the demographic characteristics was found to be a significant predictor of one-year and overall survival (p&gt;0.05). Hemoglobin, NLR, PLR and LMR were not significant predictors of one-year survival and OS (p&gt;0.05). ConclusionsThe BCC was not a significant predictive factor of survival in patients with bladder cancer after radical cystectomy.

Using T stage and tumor thrombosis as predictive factors for patients with resected I-IIA small cell lung cancer: a retrospective study.

BackgroundSurgery is recognized as an important part of treating stage I–IIA small cell lung cancer (SCLC), but few studies have explored the predictive factors for overall survival (OS) or time to tumor progression (TTP). This paper aims to explore the predictive factors related to improved overall and relapse-free survival.MethodsPatients with stage I–IIA SCLC were reviewed between January 1st, 2014, and December 30th, 2016, at the Shanghai Chest Hospital. Basic patient characteristics and clinical data were collected, including age, sex, tumor (T) stage, pathological characteristics, and treatment. Patient follow-ups were conducted by checking medical records or phoning the patient, with survival data and instances of recurrence and/or metastasis being collected and recorded. Univariate and multivariate analyses were used to identify the predictive factors.ResultsA total of 59 patients were enrolled in this study, and the median follow-up duration was 53.7 months. The 3-year disease free and 3-year OS rates were 62.5% and 75.0%, respectively. The 5-year disease free and 5-year OS rates were not reached. Univariate and multivariate analyses revealed that a higher T stage [hazard ratio (HR) 3.210, P=0.048], the presence of tumor thrombosis (HR 6.021, P=0.043), and the absence of adjuvant chemotherapy (HR 3.425, P=0.059) were more reflective of shorter TTP than other factors, with the presence of adjuvant chemotherapy also correlating with improved OS.ConclusionsA patient having a T1 stage with no tumor thrombus and receiving adjuvant chemotherapy were observed as positive factors for longer periods of TTP, and adjuvant chemotherapy was a favorable predictor for the OS of patients with resected stage I–IIA SCLC.
