Nomograms forecasting long-term overall and cancer-specific survival of patients with oral squamous cell carcinoma
- Pages: 943-952
- First Published: 07 March 2018

We successfully established two nomograms predicting overall survival(OS) and cancer-specific survival(CSS) of OSCC patients collected from SEER database. The validation results of the nomograms through the concordance index (C-index) and calibration curves showed that the model were credible, which can assist surgeons in developing a more effective therapeutic regimen and conducting personalized prognostic evaluations.
The role of primary lymph node sites in survival and mortality prediction in Hodgkin lymphoma: a SEER population-based retrospective study
- Pages: 953-965
- First Published: 09 March 2018

Little is known about the role of primary lymph node sites in survival in Hodgkin lymphoma (HL). This study uses a huge population-based cohort using the SEER database. It was found that intra-abdominal LN sites predict the worst survival in HL patients and that pelvic LN sites were the most aggressive in predicting HL-specific 1-year mortality, and hence, we recommend that primary LN sites be added to future international prognostic scores for HL.

Higher than reported adolescent and young adult clinical trial enrollment during the “Golden Age” of melanoma clinical trials
- Pages: 991-996
- First Published: 25 February 2018

Adolescents and young adult (AYA) patients have had lower clinical trial accruals over the past few decades and this has led to fewer survival benefits when comparing these patients to children and older adults with cancer. Here we report nearly 1 out of 5 AYA melanoma patients enrolled on trials during the past decade when these trials improved survival substantially.

Twenty lncRNAs, 10 miRNAs, and 54 mRNAs, which are associated with the prognosis of CM, were conducted the competing endogenous network based on their regulation relationship. Squares represent miRNAs, balls represent mRNAs, and balls with a green circle around represent lncRNAs. Red means upregulated genes, while blue means downregulated genes.
Prognostic factors in breast phyllodes tumors: a nomogram based on a retrospective cohort study of 404 patients
- Pages: 1030-1042
- First Published: 26 February 2018

Stromal cell atypia was an independent prognostic factor for recurrence-free survival (RFS) in the low-risk breast phyllodes tumors. Surgical approach and tumor border were independent prognostic factors for RFS in the high-risk breast phyllodes tumors. We made a nomogram based on comprehensive consideration of the histological type, tumor border, tumor residue, mitotic activity, and degree of stromal cell hyperplasia and atypia. It could well predict the RFS probability of breast phyllodes tumors patients.
Ibrutinib versus rituximab in relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma: a randomized, open-label phase 3 study
- Pages: 1043-1055
- First Published: 13 March 2018

To our knowledge, this report is the first study of ibrutinib in a predominantly Asian population of patients with relapsed/refractory CLL/SLL and the first to compare ibrutinib with rituximab. Our results show that ibrutinib significantly improved progression-free survival, overall response rate, and overall survival compared with rituximab. Ibrutinib displayed a manageable safety profile with no new or unexpected events reported. These findings are consistent with previous studies of single-agent ibrutinib and demonstrate the efficacy and safety of ibrutinib in a predominantly Asian population of patients.

Pioglitazone and bladder cancer risk: a systematic review and meta-analysis
- Pages: 1070-1080
- First Published: 24 February 2018

Current evidence about the association between pioglitazone and bladder cancer risk remains inconsistent. This meta-analysis of two randomized controlled trials and 20 observational studies showed that use of pioglitazone might increase risk of bladder cancer. Our findings suggest a close monitoring of bladder cancer in patients with long-term and high-dose exposure to pioglitazone.

The impact of comorbidity on overall survival in elderly nasopharyngeal carcinoma patients: a National Cancer Data Base analysis
- Pages: 1093-1101
- First Published: 01 March 2018

Elderly nasopharyngeal carcinoma patients with Charlson Comorbidity Index (CCI) score of 0 had significantly higher 5-year overall survival (OS) than patients with a CCI score of 1 or >2 (53.1% vs. 42.2% vs. 32.9%, P < 0.0001). In multivariate analysis, comorbidity was a statistically significant independent prognostic factor for OS in the elderly NPC patients.
Determinants of malignant pleural mesothelioma survival and burden of disease in France: a national cohort analysis
- Pages: 1102-1109
- First Published: 26 February 2018

The analysis of a national hospital database allowed the analysis of 1890 incident malignant pleural mesothelioma managed in France in 2011 and 2012. One- and 2-year survival rates were 64% and 48%, respectively. Median survival was 14.9 months. The mean cost per patient was 27,624 ± 17,263 euros After adjusting to age, sex, and co-morbidities, social deprivation index was not significantly associated with survival but living in Rural/semi-rural area was associated with better 2-year survival (HR: 0.83 [95% CI: 0.73–0.94]; P < 0.01).

Comparison of survival between right-sided and left-sided colon cancer in different situations
- Pages: 1141-1150
- First Published: 13 March 2018

The relationship between survival and tumor location in colon cancer was not straightforward. There is a need for further subdivisions when analyzing the survival difference between right-sided colon cancer (RSCC) and left-sided colon cancer (LSCC). We found that RSCC patients had better prognosis than LSCC in stage II disease or mucinous adenocarcinoma/signet ring cell carcinoma patients.

Comparison and validation of the prognostic value of preoperative systemic immune cells in hepatocellular carcinoma after curative hepatectomy
- Pages: 1170-1182
- First Published: 13 March 2018

In this study, we developed two nomograms to predict postoperative recurrence-free survival (RFS) and overall survival (OS), respectively, after comparisons of the systemic inflammatory/immune cells prognostic scores. The nomogram-predicted probability of RFS was associated with peritumoral necroinflammatory activity scores. The proposed nomograms included NMLR had accurate prognostic prediction in patients with HCC after curative hepatectomy.
Racial/ethnic disparities in de novo metastases sites and survival outcomes for patients with primary breast, colorectal, and prostate cancer
- Pages: 1183-1193
- First Published: 26 February 2018

Racial disparities in cancer mortality still exist despite improvements in treatment strategies leading to improved survival for many cancer types. Data from SEER 2010–2014 were utilized to assess racial/ethnic differences in site of de novo metastasis and relative survival associated with de novo metastasis by race/ethnicity. In conclusion, de novo metastasis is a major contributor to cancer mortality among patients with cancer in the USA.
Polymorphism rs2682818 in miR-618 is associated with colorectal cancer susceptibility in a Han Chinese population
- Pages: 1194-1200
- First Published: 13 March 2018

We found that individuals carrying the AA or AC/AA genotype had a decreased CRC susceptibility compared with the CC genotypes(OR = 0.54, 95% CI = 0.37–0.79 for AA vs. CC, in co-dominant model; OR = 0.82, 95% CI = 0.68–0.99 for AC/AA vs. CC, in dominant model). It is the first study to investigate the association between rs2682818 and CRC susceptibility and this finding could be a meaningful hint for further relevant studies.

Population-based differences in the outcome and presentation of lung cancer patients based upon racial, histologic, and economic factors in all lung patients and those with metastatic disease
- Pages: 1211-1220
- First Published: 13 March 2018

Our comprehensive study investigates ethnicity (nine different groups), marital status, treatment factors, standard histopathologic prognostic variables, and economic factors to see whether ethnicity is related to presentation or outcomes in lung cancer. We demonstrate that disparities in income, marriage, and insurance rather than ethnicity affect the survival of patients with lung cancer.

Mitochondrial Acetyl-CoA Synthetase 3 is Biosignature of Gastric Cancer Progression
- Pages: 1240-1252
- First Published: 01 March 2018

The cholesterogenic committing step enzyme (HMGCR) is not important in GCa patients, which explain the failure of statins in GCa clinical trials. However, the mitochondrial acetyl-CoA producer (ACSS3), and lower-mevalonate lipidomes are biosignatures for GCa progression. Interfering ACSS3 expression could almost abolished GCa cell growth under starvation stress. This study suggesting a targeting value of ACSS3 for GCa therapy.

Clofarabine exerts antileukemic activity against cytarabine-resistant B-cell precursor acute lymphoblastic leukemia with low deoxycytidine kinase expression
- Pages: 1297-1316
- First Published: 23 February 2018

We demonstrated that DCK knockout by genome editing with a CRISPR-Cas9 system in an Ara-C-sensitive-ALL cell line induced resistance to Ara-C and clofarabine, a second-generation deoxyadenosine analog, and that higher DCK expression was associated with higher AraC sensitivity in a series of B-cell precursor ALL (BCP–ALL) cell lines. In contrast, sensitivity to clofarabine was only marginally associated with DCK gene expression level, suggesting the high antileukemic potential of clofarabine may overcome low DCK expression in Ara-C-resistant BCP–ALL.

Gene panel testing of 5589 BRCA1/2-negative index patients with breast cancer in a routine diagnostic setting: results of the German Consortium for Hereditary Breast and Ovarian Cancer
- Pages: 1349-1358
- First Published: 09 March 2018

In this case-control study of well-characterized breast cancer patients, we confirm ATM, CHEK2, PALB2, CDH1, and TP53 as BC risk genes, no association was observed for NBN. We demonstrate a significant association of deleterious variants in the CHEK2, PALB2, and TP53 genes with bilateral BC and both, ATM and CHEK2, were negatively associated with TNBC and (ER)-negative tumor phenotypes. Our study confirmed the benefit of multi-gene testing for risk assessment in BC families while clinical phenotypes associated with non-BRCA1/2 gene mutations remain to be determined.

Apoptin-derived peptide reverses cisplatin resistance in gastric cancer through the PI3K–AKT signaling pathway
- Pages: 1369-1383
- First Published: 09 March 2018

Apoptin-derived peptide (AdP) is an antitumor polypeptide constructed in our laboratory that has been used to combat cisplatin (CDDP) resistance in GC cells. AdP exerted a specific cytotoxic effect on GC cells and CDDP-resistant GC cells, and suppressed invasion and migration. AdP inhibited the expression of p85, AKT, p-p85, p-AKT, multidrug resistance 1 (MDR1), and aryl hydrocarbon nuclear translocator (ARNT) within the PI3K/AKT/ARNT signaling pathway.
Genomic complexity in pediatric synovial sarcomas (Synobio study): the European pediatric soft tissue sarcoma group (EpSSG) experience
- Pages: 1384-1393
- First Published: 13 March 2018

This study analyzes 61 pediatric/adolescent/young adults (<25 years) with localized synovial sarcoma prospectively enrolled in the European EpSSG-NRSTS05 protocol to demonstrate that somatic genomic index (GI) analyzed using comparative genomic hybridization had a high prognostic value in pediatric synovial sarcoma as an independent prognostic factors. It demonstrates that patients with tumor harboring high GI had worse five-year event-free and metastatic-free survivals comparing to ones with no genomic instability, and that therefore GI could be used to stratify more accurately patients in the future.
Increased expression of miR-641 contributes to erlotinib resistance in non-small-cell lung cancer cells by targeting NF1
- Pages: 1394-1403
- First Published: 01 March 2018

We first time determined the role of miR-641 on the erlotinib resistance development in NSCLC cells. Our findings suggest that upregulated expression of miR-641 was significantly associated with erlotinib resistance development in NSCLC cells. Our findings may also aid in the development of potential therapeutics for the treatment of erlotinib-resistant NSCLC.

Physical activity across the lifespan and liver cancer incidence in the NIH-AARP Diet and Health Study cohort
- Pages: 1450-1457
- First Published: 13 March 2018

While physical activity has been associated with lower risk of developing liver cancer, most studies assess physical activity only at a single point in time, often in midlife. Our findings that, compared to individuals who reported little activity over the life course, only sustained physical activity was associated with lower liver cancer risk, offer support for federal recommendations to maintain physical activity both as a young and as an older adult.
Establishment and validation of a two-step screening scheme for improved performance of serological screening of nasopharyngeal carcinoma
- Pages: 1458-1467
- First Published: 25 February 2018

A simple two-step screening scheme was established to improve the PPV of the screening, with the combination of EBNA1/IgA and VCA/IgA in the first step of screening and anti-EAs in the second step. The PPV could be increased from 4.69% in the first step of screening to 18.52% after the second step of screening. With this two-step serological screening, more people could be benefited from the screening program.
Prostate cancer surveillance by occupation and industry: the Canadian Census Health and Environment Cohort (CanCHEC)
- Pages: 1468-1478
- First Published: 01 March 2018

We examined occupation, industry, prostate cancer, and patterns of prostate cancer rates using a large Canadian worker cohort. Increased risks were observed in white-collar, agriculture, and protective services occupations, and decreased risks were observed in construction and transportation occupations across men aged 25–74 years. These findings emphasize the need for further study of job-related exposures and the potential influence of non-occupational factors such as screening behaviours.

The international trends between 1973 and 2007 showed that ASRs of lung cancer among males were declining in 13 of 18 selected Americas, Oceania, and Europe populations, with AAPC from −0.7% to −2.9%. Whereas the rates among females in 18 selected populations were increasing, with AAPC from 1.3% to 5.0%. The increasing and decreasing trends of ASRs of lung cancer in Asia have an geographic variation but no gender differences.
Disparities in cancer survival and incidence by metropolitan versus rural residence in Utah
- Pages: 1490-1497
- First Published: 13 March 2018

Cancer disparities in rural and frontier communities are an important issue in Utah because much of Utah is sparsely populated. Patients with cancer from rural counties in Utah were more likely to be older, American Indian/Alaskan Native, non-Hispanic, male, and diagnosed at higher stage. Rural residents had a five-year relative survival that was 5.2% lower than metropolitan residents and a 10% increase in risk of death (HR = 1.10, 95% CI = 1.03, 1.18) after adjustment for multiple factors.
Socioeconomic and demographic inequalities in stage at diagnosis and survival among colorectal cancer patients: evidence from a Swiss population-based study
- Pages: 1498-1510
- First Published: 26 February 2018

This is the first population-based study in Switzerland investigating socioeconomic and demographic inequalities in stage at diagnosis and survival among patients with colorectal cancer (CRC). This study describes high-risk groups for later stage CRC diagnosis (patients with low SEP) and poorer disease-specific survival (non-Swiss and patients living in nonurban areas). Swiss public health strategies should facilitate equal access to CRC screening and optimal CRC care for all social groups and in all regions of Switzerland.
Being present: oncologists' role in promoting advanced cancer patients' illness understanding
- Pages: 1511-1518
- First Published: 26 February 2018

In this longitudinal cohort study that included 209 patients with late-stage cancers, patients were over two-and-a-half times as likely to report that their disease was late-stage if an oncologist was present versus not present for their scan results discussion in clinic. Our findings suggest that it is important for oncologists to be present during clinic visits in which scan results are discussed for patients to understand their cancer is at a late-stage.
Association between preoperative serum insulin levels and lymph node metastasis in endometrial cancer—a prospective cohort study
