RESUMEN

BACKGROUND: Human enabled homolog (ENAH; also known as human ortholog of mammalian enabled, hMENA) is a member of the enabled/vasodilator-stimulated phosphor protein family that regulates fibroblast movement and nervous system development. The ENAH over-expression promotes breast cancer (BC) cell invasion and metastasis. METHODS: We studied ENAH mRNA expression in various tumors and normal tissues using the ONCOMINE database, and in an array of cancer cell lines using Cancer Cell Line Encyclopedia data. We also investigated the prognostic value of ENAH expression in patients with BC using Kaplan-Meier plots. RESULTS: Compared with normal tissues, ENAH expression levels were markedly elevated in BC. We identified a correlation between low ENAH and superior relapse-free survival (RFS) of patients with BC; specifically, those with ER(-), HER-2(+), Grade 3 and wild-type TP53 subtypes. Additionally, a correlation was detected between low ENAH and prolonged overall survival of patients with luminal B disease. CONCLUSION: ENAH is a potential biomarker and important prognostic factor in BC.

RESUMEN

BACKGROUND: PEG-rhG-CSF reduces neutropenia and improves chemotherapy safety. In China's registration trial (CFDA: 2006L01305), we assessed its efficacy and safety against rhG-CSF, and prospectively explored its value over multiple cycles of chemotherapy. METHODS: In this open-label, randomized, multicenter phase 3 study, breast cancer patients (n = 569) were randomized to receive PEG-rhG-CSF 100 µg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 µg/kg/d after chemotherapy. The primary endpoints were the incidence and duration of grade 3/4 neutropenia during cycle 1. Secondary endpoints included the incidence and duration of grade 3/4 neutropenia during cycles 2-4, the incidence of febrile neutropenia, and the safety. RESULTS: A once-per-cycle PEG-rhG-CSF at either 100 µg/kg or 6 mg was not different from daily injections of rhG-CSF for either incidence or duration of grade 3/4 neutropenia. Interestingly, a substantial difference was noted during cycle 2, and the difference became bigger over cycles 3-4, reaching a statistical significance at cycle 4 in either incidence (P = 0.0309) or duration (P = 0.0289) favoring PEG-rhG-CSF. A significant trend toward a lower incidence of all-grade adverse events was noted at 129 (68.98%), 142 (75.53%), and 160 (82.47%) in the PEG-rhG-CSF 100 µg/kg and 6 mg and rhG-CSF groups, respectively (P = 0.0085). The corresponding incidence of grade 3/4 drug-related adverse events was 2/187 (1.07%), 1/188 (0.53%), and 8/194 (4.12%), respectively (P = 0.0477). Additionally, PFS in metastatic patients preferred PEG-rhG-CSF to rhG-CSF despite no significance observed by Kaplan-Meier analysis (n = 49, P = 0.153). CONCLUSIONS: PEG-rhG-CSF is a more convenient and safe formulation and a more effective prophylactic measure in breast cancer patients receiving multiple cycles of chemotherapy.

RESUMEN

This study aimed to investigate the prognostic significance of tumor mutation burden (TMB) among patients with non-small cell lung cancer (NSCLC) who received platinum-based adjuvant chemotherapy. Tumor tissue specimens after surgical resection were collected for DNA extraction. Somatic mutation detection and TMB analysis were conducted using next-generation sequencing (NGS). Recurrence status of the patients was assessed in the hospital during the adjuvant chemotherapy period, and long-term survival data of patients were obtained by telephone follow-up. Univariate analysis between TMB status and prognosis was carried out by survival analysis. A retrospective review of 78 patients with non-squamous NSCLC who received platinum-based adjuvant chemotherapy showed a median disease-free survival of 3.6 years and median overall survival (OS) of 5.3 years. NGS analysis exhibited that the most common mutated somatic genes among the 78 patients were tumor suppressor protein p53 (TP53), epidermal growth factor receptor, low-density lipoprotein receptor related protein 1B, DNA methyltransferase 3 alpha and FAT atypical cadherin 3, and their prevalence was 56.4%, 48.7%, 37.2%, 30.7%, and 25.6%, respectively. TMB status was divided into TMB-L (≤ 4.5/Mb) and TMB-H (> 4.5/Mb) based on the median TMB threshold. Relevance of TMB to prognosis suggested that the median OS of patients with TMB-L was significantly longer than that of patients with TMB-H (NR vs. 4.6, P = 0.014). Higher TMB status conferred a worse implication on OS among patients with non-squamous NSCLC who received platinum-based adjuvant chemotherapy.

RESUMEN

Coronavirus disease 2019 (COVID-19) is caused by a new coronavirus, namely severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is currently spreading all over the world. In this paper, we developed a practical model for identifying the features of cytokine storm, which is common in acute infectious diseases and harmful manifestation of COVID-19, by distinguishing major and minor clinical events. This model is particularly suitable for identifying febrile and infectious diseases like COVID-19. Based on this model, features of cytokine storm and pathogenesis of COVID-19 have been proposed to be a consequence of the disequilibrated cytokine network resulting from increased biological activity of transforming growth factor-ß (TGF-ß), which induces certain clinical manifestations such as fatigue, fever, dry cough, pneumonia, abatement and losing of olfactory, and taste senses in some patients. Research and clarification of the pathogenesis of COVID-19 will contribute to precision treatment. Various anti-TGF-ß therapies may be explored as potential COVID-19 treatment. This novel model will be helpful in reducing the widespread mortality of COVID-19.

RESUMEN

PURPOSE: A thymoma is a tumor arising from the epithelium of the thymus, mostly occurring in the anterior mediastinum. The incidence of this disease is low and research progress in this field is slow. Consequently, there is an urgent need to investigate the correlation between molecular regulation and the prediction of survival and prognosis in patients with thymoma. METHODS: We collected thymoma datasets from The Cancer Genome Atlas (TCGA). Differentially expressed genes (DEGs) of TCGA datasets were then determined using R software. A gene signature was obtained by screening prognostic DEGs from the TCGA datasets using univariate and multivariate Cox survival analysis. The summation of the weighted expression levels was calculated as a risk score, which could then be used to predict the survival rate and prognosis of patients with thymoma. The validity of this model was verified by the analysis of receiver operating characteristic (ROC) curves and area under the curve (AUC). RESULTS: In total, 297 DEGs were identified from the integrated results of TCGA datasets. A seven-gene signature, along with a regression model of prognostic risk, was obtained by Cox survival analysis. The expression levels of the seven genes were then weighted and summed to calculate the risk score for each sample. Patients were effectively divided into high- and low-risk groups using the median risk score (P < 0.05). ROC analysis showed that this Cox regression model was effective in predicting the prognosis of patients with thymus tumors (AUC = 0.983, P < 0.05). CONCLUSION: For the first time, we identified an effective seven-gene signature in patients with thymic tumors. In the future, the risk and prognosis of patients can be preliminarily assessed using this model, although further testing is required to improve rigor.

RESUMEN

The prognostic value of phosphatase and tensin homolog (PTEN) negativity in breast cancer has been evaluated by many studies but remains controversial. We conducted a meta-analysis to assess the association of PTEN negativity with overall survival and disease-free survival. Thirty-two studies with 4393 patients were identified. PTEN negativity was significantly associated with unfavorable overall survival in breast cancer (hazard ratio=1.89, 95% confidence interval 1.58-2.26), with low heterogeneity among the studies (I(2)=25%, P=0.160) and no evidence for publication bias. Meta-analysis of multivariate hazard ratios and sensitivity analyses did not materially change the results. The data on disease-free survival was heterogeneous (I(2)=61.9%, P<0.001), with a summary hazard ratio of 1.57 (95% confidence interval 1.31-1.89). The exact source of heterogeneity remains unclear. We thus concluded that PTEN negativity was significantly associated with unfavorable prognosis in terms of overall survival in breast cancer.

RESUMEN

In this study, we investigated the efficacy of sequential cytokine-induced killer cell (CIK) immunotherapy with gemcitabine plus cisplatin (GC) regimen chemotherapy in metastatic nasopharyngeal carcinoma (NPC) patients. Between September 2006 and April 2010, 222 NPC patients with distant metastasis after radiotherapy completion were retrospectively analyzed: 112 patients received 4-6 cycles of GC chemotherapy at 4-week intervals, followed by at least 4 cycles of CIK immunotherapy at 2-week intervals (GC+CIK group); the remaining 110 patients received 4-6 cycles of GC chemotherapy alone (GC group). The evaluation of long-term efficacy showed that the progression-free survival (PFS) rate was significantly higher in the GC+CIK group (log-rank test; p = 0.009), as was the overall survival (OS) rate (p = 0.006). In conclusion, sequential CIK treatment may be effective in enhancing the therapeutic efficacy of GC chemotherapy for metastatic NPC patients. This study provides a basis for alternative therapeutic strategies for metastatic NPC.

RESUMEN

The prognostic value of phosphorylated Akt (pAkt) overexpression in breast cancer has been investigated by many studies with inconsistent results. This systematic review was conducted to evaluate the association of pAkt overexpression with breast cancer prognosis in terms of overall survival and disease-free survival. Three electronic databases (PubMed, EMBASE and Chinese Biomedical Literature Database) were comprehensively searched. Hazard ratios (HRs) with 95% confidence intervals (CIs) from different studies were combined using the random-effects model. In total, 33 studies with 9,836 patients were included for final analysis. The summary HR for overall survival and disease-free survival was 1.52 (95% CI: 1.29-1.78) and 1.28 (95% CI: 1.13-1.45), respectively, indicating higher risk of death and disease recurrence associated with pAkt overexpression. The results were robust in sensitivity analyses by omitting one study each time and by using the fixed-effects model instead. Subgroup and meta-regression analyses did not show that the prognostic effect of pAkt overexpression would change materially with such factors as population, status of hormone receptors, hormonal or trastuzumab treatment given, analyzing method (univariate versus multivariate) and methodological quality of the original studies. In conclusion, the available evidence suggests that pAkt overexpression is an adverse prognostic factor for breast cancer.

RESUMEN

The aim of this investigation was to compare clinical pathological characteristics and prognosis of very young and older triple-negative breast cancer (TNBC) patients in order to assess their relevance to TNBC in an younger population. Data of TNBC patients diagnosed between 2002 and 2007 were retrospectively analyzed by computer based chart information. Baseline tumor characteristics, biological markers, and patients' prognosis were compared between very young (≤ 35 years) and older (>35 years) TNBC patients. In the 216 cases of operable TNBC patients, 48 (22.2%) were ≤ 35 years and 168 (77.8%) were >35 years. Very young TNBC patients had showed a high clinical stage, more positive lymph nodes, Ck5/6 and/or EGFR expression (P = 0.049, 0.006, and 0.011, respectively). Compared to older TNBC patients, very young TNBC patients have short disease-free survival (P = 0.031), while no significant difference was found in overall survival (OS) (P = 0.075). In multivariate analysis, lymph node metastatic status was a significant predictor of OS. TNBC of very young patients is an aggressive breast cancer subtype, but the overall survival of both young and older TNBC patients did not have significant differences.

RESUMEN

Our objective is to investigate the expression of CD147 and metallo-proteinase 9 (MMP9) in patients with basal-like breast cancer (BLBC) so as to determine whether these two genes may be correlated with prognosis of BLBC. We examined the expression of the CD147 and MMP9 in BLBC by immunohistochemistry. Furthermore, we analyzed the correlation between BLBC and several factors related to tumor progression, along with the prognostic value of BLBC. BLBC was significantly associated with CD147 and MMP9 expression (P = 0.000), and prone to lymph node metastasis and distant metastasis. Patients with BLBC showed shorter disease-free survival (P = 0.005) and overall survival (OS) (P = 0.011). In univariate analysis, CD147, MMP9, lymph node metastasis and clinical stage are independent prognostic factors affecting OS. In multivariate analysis, only clinical stage was identified as an independent prognostic factor. Patients with BLBC have a high expression of CD147 and MMP9; BLBC is correlated with a poor prognosis.

RESUMEN

In this study, we evaluate the efficacy of autologous cytokine-induced killer cells (CIK) transfusion used in combination with gemcitabine and cisplatin (GC) chemotherapy to treat nasopharyngeal carcinoma in patients with distant metastasis after radiotherapy. From September 2007 to August 2008, 60 patients with distant metastasis after radiotherapy were followed up and were randomly divided into 2 groups. The 30 patients in the GC+CIK group were treated with adoptive autologous CIK cell transfusion in combination with GC chemotherapy; the 30 patients in the GC group were treated with chemotherapy alone. Short-term efficacy evaluation revealed that in the GC+CIK group, there were 3 cases of complete remission, 18 cases of partial remission, 2 cases of stabilization of disease, and 7 cases of progression of disease and the total effective rate was 70% (21/30). In the GC group, there were 0 cases of complete remission, 14 cases of partial remission, 3 case of stable disease, and 13 cases of progressive disease and the total effective rate was 46.7% (14/21). Kaplan-Meier survival analysis showed that the overall survival of the GC+CIK group was higher than that of the GC group, but the difference was not significant (P=0.1374, log-rank test). However, the progression-free survival of the GC+CIK group was significantly higher than that of the GC group (P=0.0234, log-rank test). Thus, our study indicated that CIK cell transfusion therapy used in combination with GC chemotherapy may be a more effective treatment for postradiotherapy distant metastasis of nasopharyngeal carcinoma patients.

RESUMEN

BACKGROUND: Epidermal growth factor receptor gene copy number (EGFR GCN) has been heavily investigated as a potential predictive biomarker for the treatment of metastatic colorectal cancer (mCRC) with anti-EGFR monoclonal antibodies (MAbs). The objective of this study was to systematically review current evidences on this issue. METHODS: PubMed, EMBASE, The Cochrane Library, Chinese Biomedical Literature Database, Wanfang Data, and the conference abstracts of American Society of Clinical Oncology and European Society of Medical Oncology were comprehensively searched. Studies that reported the objective response rate (ORR), progression-free survival, and/or overall survival of mCRC patients treated with anti-EGFR MAbs, stratified by EGFR GCN status, were included. The effect measures for binary outcome (response) and time-to-event outcomes (progression-free survival and overall survival) were risk difference and hazard ratio, respectively. Statistical heterogeneity among the studies was assessed by the Cochran's Q-test and the I2 statistic. If appropriate, a quantitative synthesis of data from different studies would be conducted with a random-effects model. RESULTS: Nineteen eligible studies were identified. The criteria for increased EGFR GCN (GCN+) were highly inconsistent across different studies. The prevalence of GCN + ranged from 6.9% to 88.9%, and the difference in ORR between patients with GCN + and those with non-increased EGFR GCN (GCN-) varied from -28% to 84%. Because of the significant heterogeneity, no quantitative synthesis of data was performed. There was a general trend towards higher ORR in patients with GCN+. The difference in ORRs between patients with GCN + and those with GCN- was even greater in KRAS wild-type patients, while in KRAS mutated patients the difference often did not exist. Almost all patients with EGFR amplification responded to the treatment. However, the prevalence of EGFR amplification was generally low. Incomplete data on progression-free survival and overall survival seemingly supported the findings on ORR. CONCLUSIONS: Although increased EGFR GCN is generally associated with a better outcome of anti-EGFR MAbs treatment, especially among patients with wild-type KRAS, the clinical utility of this biomarker for selecting recipients of anti-EGFR MAbs would be severely limited by the heterogeneous scoring system and the poor reproducibility of EGFR GCN enumeration due to technical reasons.

RESUMEN

BACKGROUND & OBJECTIVE: 10-Hydroxycamptothecin (HCPT) is the inhibitor of topoisomerase I with anti-cancer effectiveness on several solid tumors. TUOXI (lyophilized HCPT) has higher purity and stability in comparison with solution for injection HCPT. The purpose of this study was to investigate the efficacy, toxicity, and proper dosage of TUOXI as single agent in treatment of advanced and recurrent solid tumors. METHODS: Sixty patients with the median age of 53 (range from 17 to 73 years) were enrolled into this multicenter phase II clinical trial. Among them, 18 patients were chemonaive and 42 were recurrent from chemotherapy; 22 patients with NSCLC, 12 nasopharyngeal carcinoma, 9 primary liver cancer, 9 colorectal carcinoma, 2 pancreatic carcinoma, and 6 miscellaneous malignancies. HCPT was given at the dosage of 6-8 mg/m(2) x d for 5-10 consecutive days based on the toxicity. RESULTS: Fifty-one patients were valuable for effectiveness. The objective response rate for the whole group was 15.7%. The partial remission (PR) rates were 16% for 6 mg/m(2) group and 15.4% for 8 mg/m(2) group, respectively. The PR rates were 13.7% (3/22) for NSCLC, 33.3% (3/9) for colorectal carcinoma, and 16.6% (2/12) for advanced nasopharyngeal carcinoma, respectively. The PR rate for 60 intent-to-treat patients was 13.3% (8/60). Myelosuppression was the dose-limiting toxicity and other adverse reactions included nausea/vomiting, diarrhea, and skin rash. The incidence of grade III+IV adverse events were 32%, 8%, 8%, 6%, and 4% for leucopenia, skin rash, thrombocytopenia, nausea/vomiting, and diarrhea, respectively. No renal, pulmonary, and cardiac toxicity were found. CONCLUSION: TUOXI (HCPT lyophilized powder) had relatively broad- spectrum anti-cancer efficacy and was effective on advanced or recurrent NCSLC, colorectal carcinoma, and NPC. And the recommended dosage is 6-8 mg/m(2) as 4 hours infusion for 5-10 consecutive days every 3 weeks. Further clinical investigation on large number of solid tumors cases are warranted.
