Trends in survival of patients with stage I/II Burkitt lymphoma in the United States: A SEER database analysis
- Pages: 874-881
- First Published: 31 January 2019

Patients with limited-stage BL had a significantly better 5-year overall survival (OS) in the 2002-2014 era in both univariate analysis and multivariate analysis, compared with those in the 1983-2001 era (64.1% vs 57.4%). However, clinical outcomes of elderly patients (≥60 years) and children patients (0-19 years) did not significantly improve.

Monocyte-predominant engraftment, cytokine levels and early transplant-related complications in pediatric hematopoietic stem cell recipients
- Pages: 890-901
- First Published: 28 January 2019
The onset of vascular endothelial syndromes after hematopoietic stem cell transplantation is significantly associated with monocyte-predominant engraftment (P < 0.0001). The increased production of specific cytokines, in particular RANTES, represents a marker associated with monocyte-predominant engraftment. There is close association between the prophylactic administration of defibrotide, a powerful endothelial protector, and the incidence of vascular endothelial syndromes (P < 0.0001). Given the high cost of defibrotide, selective prophylaxis may be considered for patients with extremely high values of RANTES or with monocyte engraftment.
Comparison of outcome and toxicity of postoperative intensity-modulated radiation therapy with two-dimensional radiotherapy in patients with soft tissue sarcoma of extremities and trunk
- Pages: 902-909
- First Published: 10 February 2019

Our study is the first to directly compare not only clinical survival outcomes, but also late toxicities of postoperative intensity-modulated radiation therapy (IMRT) and two-dimensional radiotherapy (2D-RT) for patients with STS of extremities and trunk, and our results demonstrated that IMRT provided better local control (5 year 91.1% vs. 80.8%) and OS (5 year 90.2% vs. 81.0%) and less severe late toxicities compared with 2D-RT.
Differences in the genomic profiles of cell-free DNA between plasma, sputum, urine, and tumor tissue in advanced NSCLC
- Pages: 910-919
- First Published: 14 February 2019

This prospective research is the first one to conduct an integrated liquid biopsy based on three types of liquid samples including plasma, sputum, and urine compared with matched tumor tissue under the same NGS platform in advanced NSCLC. It was demonstrated for the first time that sputum cfDNA can be considered as an alternative medium to liquid biopsy. And the complementarity in genomic profiles of cfDNA among various bio-samples enables the combination of plasma, sputum, and urine to detect more diver genes alterations and improve the utility of liquid biopsy in clinical practice of advanced NSCLC.
Serum folate receptor α (sFR) in ovarian cancer diagnosis and surveillance
- Pages: 920-927
- First Published: 13 February 2019

Collectively, our data demonstrate that sFR could improve diagnostic accuracy. Additionally, the monitoring of sFR and CA125 (and potentially other markers) could conceivably improve cancer surveillance, affecting prognosis. We have initiated a prospective clinical trial studying sFR induction in the initial diagnosis and surveillance of OVCA as a means to abrogate potential limitations of this biomarker.
Stereotactic body radiation therapy for hepatocellular carcinoma: Practice patterns, dose selection and factors impacting survival
- Pages: 928-938
- First Published: 31 January 2019

Stereotactic body radiation therapy is growing in use and acceptance for treating unresectable hepatocellular carcinoma. There is a wide variety of dose schemas used in clinical practice. Multiple factors are associated with dose selection and fractionation, with more favorable patients receiving higher doses and having better outcomes.
Adjuvant chemotherapy followed by concurrent chemoradiation is associated with improved survival for resected stage I-II pancreatic cancer
- Pages: 939-952
- First Published: 16 January 2019

Prior NCDB studies have demonstrated an overall survival benefit for adjuvant concurrent chemoradiation compared to chemotherapy alone for resectable pancreatic cancer. In this retrospective propensity-matched study of the NCDB including 5667 patients, postoperative chemotherapy followed by adjuvant chemoradiation showed improved survival for resected stage I-II pancreatic cancer compared to adjuvant chemoradiation or chemotherapy alone.
Serum level of soluble interleukin-2 receptor is positively correlated with metabolic tumor volume on 18F-FDG PET/CT in newly diagnosed patients with diffuse large B-cell lymphoma
- Pages: 953-962
- First Published: 20 February 2019

In DLBCL patients, high total metabolic tumor burden calculated using 18F-FDG PET/CT images at diagnosis predicts poor prognosis. We found serum level of sIL-2R represents a convenient surrogate marker to estimate metabolic tumor burden measured by 18F-FDG PET/CT that can predict treatment outcomes of patients with DLBCL.
Daily activity, mood, and quality of life in colorectal cancer patients with chemotherapy-induced peripheral neuropathy: A mediation effect analysis
- Pages: 963-971
- First Published: 11 February 2019

This is a rare study to investigate the relationship among daily activity, mood, and quality of life (QoL) in colorectal cancer patients with chemotherapy-induced peripheral neuropathy (CIPN), by using the mediation effect analysis. According to the results, the mediation effect of mood between daily activities and QoL should be further emphasized for colorectal cancer patients with CIPN.
Prognostic significance of mast cell and microvascular densities in malignant peripheral nerve sheath tumor with and without neurofibromatosis type 1
- Pages: 972-981
- First Published: 08 February 2019

This study aimed to investigate the prognostic significance of mast cells and microvascular densities in malignant peripheral nerve sheath tumor with and without neurofibromatosis type 1. Our results revelead an important novel finding by confirming the association of microvascular density in the tumor periphery (higher tercile, p = 0.019) with a decreased overall survival. Diverse mast cells and microvascular distributions suggest that angiogenesis occurs independently.
Complications and outcomes in diffuse large B-cell lymphoma with gastric lesions treated with R-CHOP
- Pages: 982-989
- First Published: 07 February 2019

Among patients with diffuse large B-cell lymphoma with gastric lesions (DLBCL-GL) treated with R-CHOP, patients with gastric complications had a lower R-CHOP completion rate and a lower complete remission rate than those without complications. The importance of this study is to provide important information about management of DLBCL-GL to prevent gastric complications, which may result in better survival.

The preoperative neutrophil-to-lymphocyte ratio is not a marker of prostate cancer characteristics but is an independent predictor of biochemical recurrence in patients receiving radical prostatectomy
- Pages: 1004-1012
- First Published: 28 January 2019

Previous studies reported the association between NLR and pathological characteristics of prostate cancer, and patients with preoperative high-NLR had significantly poorer BCR-free survival. This study contradicts these reports, and reports that there is no association between preoperative NLR and pathological features and representative molecules of biological function (eg. AR, ERG, PTEN, p-AKT, Bcl-2, Beclin-1, Ki-67) and the local microenvironment (eg. infiltrating CD3+ cells, the CD4/CD8 ratio,IFN-γ and TNF-α) of localized prostate cancer. Furthermore, it also reveals that a high NLR can serve as an independent predictor of better BCR. Additionally, univariate analysis indicated that a high NLR was associated with poor overall survival, but this correlation was not verified in the multivariate analysis. NLR, as a reliable, easily accessible and inexpensive biomarker, might benefit individual risk assessment and patient stratification.

Long-term survival outcome with tyrosine kinase inhibitors and surgical intervention in patients with metastatic or recurrent gastrointestinal stromal tumors: A 14-year, single-center experience
- Pages: 1034-1043
- First Published: 28 January 2019

The current data showed better survival in patients with metastatic or recurrent gastrointestinal stromal tumors (GISTs) who were initiated on 400 mg/d imatinib at a single institution, with an experienced GIST team. Along with appropriate patient management of maintaining imatinib treatment without unnecessary interruption, more commonly used subsequent tyrosine kinase inhibitors and active surgical intervention may also be responsible for improved survival rates.

Alerting the illusion of smoking improves quality of life in Chinese male cancer survivors
- Pages: 1066-1073
- First Published: 08 February 2019

Our study suggested the possibility that in China, where smoking prevalence is still high, continued smoking was associated with high QOL scores. The phenomenon may be obscured by some potential reasons, including subjectivity of questionnaire, Chinese special culture of tobacco use, and much more. The results reminded researchers and clinicians some underlying situations among smokers in China and prompted a strong call for the implementation of a comprehensive tobacco-control policy and specific public health educational strategies among not only lung cancer survivors but other types of cancer.
Primary small cell carcinoma of the esophagus: Comparison between a Chinese cohort and Surveillance, Epidemiology, and End Results (SEER) data
- Pages: 1074-1085
- First Published: 10 February 2019

Although there are huge differences in the tumor characteristics and treatment modalities of SCCE between Chinese and U.S. patients, the prognosis of SCCE is equally poor in both. Surgery should be considered for patients with localized disease, while chemoradiotherapy is recommended for patients with regional and extensive disease. This study will be helpful to guide the treatment of SCCE in the future.
The relation of radiological tumor volume response to histological response and outcome in patients with localized Ewing Sarcoma
- Pages: 1086-1094
- First Published: 21 February 2019

Early adequate tumor volume response (TVR) does not predict outcome, so modification of chemotherapy in case of an inadequate early TVR may not be justifiable. However, late adequate TVR and poor histological response were independent predictors of adverse outcome; therefore, patients with late-phase inadequate TVR might benefit from augmented treatment.
A system-based intervention to reduce Black-White disparities in the treatment of early stage lung cancer: A pragmatic trial at five cancer centers

- First Published: 04 February 2019

A multi-faceted intervention tested in five cancer centers using the transparency of race-specific data feedback, real-time warnings derived from EHRs, and patient-centered navigation improved care for both Black and White patients while reducing racial differences. Application of this system-based, pragmatic approach at a health system level could have positive effects on treatment completion, equity and overall outcomes.

The discovery and characterization of K-563, a novel inhibitor of the Keap1/Nrf2 pathway produced by Streptomyces sp
- Pages: 1157-1168
- First Published: 08 February 2019

In the present study, we conducted high-throughput luciferase reporter screening to discover new Keap1/Nrf2 pathway inhibitors. From our screening, the novel compound K-563 was isolated from the culture broth of Streptomyces sp. 3728-17 and was found to selectively inhibit the reporter activity of the Keap1/Nrf2 pathway. Furthermore, K-563 inhibited the expression of Keap1/Nrf2 pathway downstream proteins, GSH synthesis and ROS resistance through the suppression of the Keap1/Nrf2 pathway downstream gene expression.
Disruption of erythroid nuclear opening and histone release in myelodysplastic syndromes
- Pages: 1169-1174
- First Published: 30 January 2019

Our paper presents a conceptual advance of developmental and cell biology by revealing the conserved nuclear envelop and histone dynamic changes in human and mouse terminal erythropoiesis. We find that patients with myelodysplastic syndrome (MDS) exhibited significant defects in histone release in the dysplastic erythroblasts. Our results indicate that disruption of the histone release process plays a critical role in the pathogenesis of dyserythropoiesis in MDS.

Magnolol induces cell death through PI3K/Akt-mediated epigenetic modifications boosting treatment of BRAF- and NRAS-mutant melanoma
- Pages: 1186-1196
- First Published: 21 February 2019

To improve treatment of BRAF/MEK inhibitors and chemotherapy in BRAF/NRAS mt melanoma, the benefit of the plant-derived compound magnolol alone or in combination has been investigated. Magnolol decimated BRAF/NRAS mt cancer cells alone or in combination albeit at a lower dosage than magnolol alone. Mechanistically, magnolol-induced cell death in BRAF/NRAS mt melanoma through PI3K/Akt dependent epigenetic remodeling.

Correlation between immune signature and high-density lipoprotein cholesterol level in stage II/III colorectal cancer
- Pages: 1209-1217
- First Published: 07 February 2019

This study reveals that a low HDL-C level in stage II/III CRC patients predicts poor prognosis. The correlation between the HDL-C level and immune signature in tissue specimens supports the hypothesis that HDL-C is likely to play an inhibitory role in tumour development via affecting immune responses.
The diagnostic accuracy of circulating free DNA for the detection of KRAS mutation status in colorectal cancer: A meta-analysis
- Pages: 1218-1231
- First Published: 21 February 2019

Circulating free DNA (cfDNA) has high concordance rate in detecting KRAS mutation status in colorectal cancer (CRC) patients, compared with tumor tissues. cfDNA has adequate diagnostic performance and could act as an effective method to detect KRAS mutation status in CRC patients. Due to its high specificity and non-invasive nature, cfDNA might be a promising screening tool for CRC.

Targeting of the HER2/HER3 signaling axis overcomes ligand-mediated resistance to trastuzumab in HER2-positive breast cancer
- Pages: 1258-1268
- First Published: 31 January 2019

HER2-targeted therapy, especially the anti-HER2 antibody trastuzumab, is standard for HER2-positive breast cancer; however, its efficacy is limited in a subpopulation of patients. The current study found that blockade of HER2 and HER3 using pertuzumab and patritumab could overcome resistance to trastuzumab therapy in heregulin-expressing and HER2-positive breast cancer, which could be exploited clinically.
Recognition of HER2 expression in hepatocellular carcinoma and its significance in postoperative tumor recurrence
- Pages: 1269-1278
- First Published: 04 February 2019

The ERBB2 oncogene hypothesis is challenged in hepatocellular carcinoma (HCC) with the conflicting evidences of human epidermal growth factor receptor 2 (HER2) overexpression. Our results showed that HER2 expression pattern is linked with tumor stage and overall survival; the transforming function of HER2 is found more relevant through β-catenin and SMAD3. HER2-targeted treatment is indicated to suppress the HER2-mediated tumor growth during postoperative liver regeneration.

Painting a portrait: Analysis of national health survey data for cancer genetic counseling
- Pages: 1306-1314
- First Published: 07 February 2019

Despite literature describing the geographic and sociodemographic distribution of cancer genetic testing, work focused on cancer genetic counseling is limited and contradictory. Using data from the 2015 National Health Survey, genetic counseling appears to be accessed by individuals of diverse racial/ethnic backgrounds, with various insurance coverage and educational levels, and across broad age ranges and geographic regions with sex being the only factor that independently predicted receipt of counseling across both the affected and unaffected populations.
