Antibodies to programmed cell death-1 (PD-1), such as nivolumab, have shown promising clinical activity in patients with advanced non-small-cell lung cancer (NSCLC), but their efficacy appears to be less pronounced in patients with such tumors harboring epidermal growth factor receptor gene (EGFR) mutations. Recent findings suggest that patients with EGFR mutation-positive NSCLC who develop resistance to tyrosine kinase inhibitors (TKIs) due to mechanisms other than acquisition of the secondary T790M mutation of EGFR are more likely to benefit from nivolumab treatment, possibly as a result of a higher level of expression of the PD-1 ligand PD-L1, than are patients who are T790M-positive. The WJOG8515L study (UMIN ID: 000021133) is a randomized phase II trial to compare nivolumab with the combination of carboplatin and pemetrexed in patients with EGFR mutation-positive nonsquamous NSCLC who have developed resistance to EGFR-TKIs due to mechanisms other than T790M. Eligible patients are those with stage IV or recurrent EGFR mutation-positive NSCLC who experience disease progression after therapy with more than 1 EGFR-TKI, including gefitinib, erlotinib, or afatinib; they must show no evidence of the T790M mutation on analysis of a tumor biopsy specimen obtained after progression on such EGFR-TKI therapy, or, if T790M is detected, they must again experience progression on subsequent treatment with a third-generation EGFR-TKI. The primary endpoint is progression-free survival (PFS), and secondary end points include overall survival (OS), objective response rate, duration of response, safety, and OS and PFS according to PD-L1 expression level. Recruitment started in May 2016 and is ongoing.

TP53 is mutated in 20-25% of aggressive B-cell lymphoma (B-NHL). To date, no studies have addressed the impact of TP53 mutations in prospective clinical trial cohorts. To evaluate the impact of TP53 mutation to current risk models in aggressive B-NHL, we investigated TP53 gene mutations within the RICOVER-60 trial. Of 1,222 elderly patients (aged 61-80 years) enrolled in the study and randomized to six or eight cycles of CHOP-14 with or without Rituximab (NCT00052936), 265 patients were analyzed for TP53 mutations. TP53 mutations were demonstrated in 63 of 265 patients (23.8%). TP53 mutation was associated with higher LDH (65% vs. 37%; p < 0.001), higher international prognostic index-Scores (IPI 4/5 27% vs. 12%; p = 0.025) and B-symptoms (41% vs. 24%; p = 0.011). Patients with TP53 mutation were less likely to obtain a complete remission CR/CRu (CR unconfirmed) 61.9% (mut) vs. 79.7% (wt) (p = 0.007). TP53 mutations were associated with decreased event-free (EFS), progression-free (PFS) and overall survival (OS) (median observation time of 40.2 months): the 3 year EFS, PFS and OS were 42% (vs. 60%; p = 0.012), 42% (vs. 67.5%; p < 0.001) and 50% (vs. 76%; p < 0.001) for the TP53 mutation group. In a Cox proportional hazard analysis adjusting for IPI-factors and treatment arms, TP53 mutation was shown to be an independent predictor of EFS (HR 1.5), PFS (HR 2.0) and OS (HR 2.3; p < 0.001). TP53 mutations are independent predictors of survival in untreated patients with aggressive CD20+ lymphoma. TP53 mutations should be considered for risk models in DLBCL and strategies to improve outcome for patients with mutant TP53 must be developed.

Purpose Early thymic precursor (ETP) acute lymphoblastic leukemia (ALL) is an immunophenotypically defined subgroup of T-cell ALL (T-ALL) associated with high rates of intrinsic treatment resistance. Studies in children have shown that the negative prognostic impact of chemotherapy resistance is abrogated by the implementation of early response-based intensification strategies. Comparable data in adults are lacking. Patients and Methods We performed comprehensive clinicobiologic, genetic, and survival analyses of a large cohort of 213 adult patients with T-ALL, including 47 patients with ETP-ALL, treated in the GRAALL (Group for Research on Adult Acute Lymphoblastic Leukemia) -2003 and -2005 studies. Results Targeted next-generation sequencing revealed that the genotype of immunophenotypically defined adult T-ALL is similar to the pediatric equivalent, with high rates of mutations in factors involved in cytokine receptor and RAS signaling (62.2%), hematopoietic development (29.7%), and chemical modification of histones (48.6%). In contrast to pediatric cases, mutations in DNA methylation factor genes were also common (32.4%). We found that despite expected high levels of early bone marrow chemotherapy resistance (87%), the overall prognosis for adults with ETP-ALL treated using the GRAALL protocols was not inferior to that of the non-ETP-ALL group (5-year overall survival: ETP, 59.6%; 95% CI, 44.2% to 72.0% v non-ETP, 66.5%; 95% CI, 58.7% to 73.2%; P = 0.33) and that allogeneic stem-cell transplantation had a beneficial effect in a large proportion of patients with ETP-ALL. Conclusion Our results suggest that the use of response-based risk stratification and therapy intensification abrogates the poor prognosis of adult ETP-ALL.

Ceritinib is a next-generation anaplastic lymphoma kinase (ALK) inhibitor, which has shown robust anti-tumour efficacy, along with intracranial activity, in patients with ALK-rearranged non-small-cell lung cancer. In phase 1 and 2 studies, ceritinib has been shown to be highly active in both ALK inhibitor-naive and ALK inhibitor-pretreated patients who had progressed after chemotherapy (mostly multiple lines). In this study, we compared the efficacy and safety of ceritinib versus single-agent chemotherapy in patients with advanced ALK-rearranged non-small-cell lung cancer who had previously progressed following crizotinib and platinum-based doublet chemotherapy.

Findings from the global phase III ALEX trial unequivocally show that alectinib is superior to crizotinib as first-line therapy for ALK+ non-small cell lung cancer. Alectinib more than doubled progression-free survival, significantly reduced the incidence of brain and CNS metastases, and should be considered the new standard of care.

We compared the efficacy and safety of gemcitabine, cisplatin, prednisone and thalidomide (GDPT) with standard CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone) for patients with newly diagnosed peripheral T-cell lymphoma (PTCL) in a prospective randomized controlled and open-label clinical trial. Between July 2010 and June 2016, 103 patients were randomly allocated into two groups, of whom 52 were treated with GDPT therapy and 51 with CHOP therapy. The 2-year progression-free survival (PFS) and overall survival (OS) rates were better in the GDPT group than in the CHOP group (57% vs. 35% for 2-year PFS, P = 0·0035; 71% vs 50% for 2-year OS, P = 0·0001). The complete remission rate (CRR) and the overall response rate (ORR) in the GDPT group were higher than in the CHOP group (52% vs. 33%, P = 0·044 for CRR; 67% vs. 49%, P = 0·046 for ORR). Haemocytopenia was the predominant adverse effect, and acute toxicity was moderate, tolerable and well managed in both arms. mRNA expression of ERCC1, RRM1, TUBB3 and TOP2A genes varied among patients but the difference did not reach statistical significance, mainly due to the relatively small sample size. The precise characters of these biomarkers remain to be identified. In conclusion, GDPT is a promising new regimen as potential first-line therapy against PTCL. This study was registered at www.clinicaltrials.gov as #NCT01664975.

HER2 is one of the predominant therapeutic targets in breast cancer. The metastatic selection process may lead to discrepancies between the HER2 status of the primary tumor and circulating tumor cells (CTCs). This study analyzed the HER2 status of CTCs in patients with HER2-positive primary breast cancer at the time of diagnosis. Aim of the study was to assess potential discordance of HER2 status between primary tumor and CTCs, as this may have important implications for the use of HER2-targeted therapy.

Our aim was to explore the impact of the HER2/neu, HER3 receptor as well as their ligands' neuregulin (NRG1) expression on the outcome of patients with metastatic colorectal cancer (mCRC). NRG1, HER2/neu and HER3 expression was evaluated in 208 patients with mCRC receiving 5-FU/LV plus irinotecan or irinotecan plus oxaliplatin as the first-line treatment. Biomarker expression was correlated with the outcome of patients. NRG1 (low: 192 vs. high: 16), HER2/neu (low: 201 vs. high: 7) and HER3 (low: 69 vs. high: 139) expressions were assessed in 208 patients. High versus low NRG1 expression significantly affected progression-free survival (PFS) [4.7 vs. 8.2 months, hazard ratio (HR): 2.45; 95% confidence interval (CI): 1.45-4.13; P=0.001], but not overall survival (OS) (15.5 vs. 20.7 months, HR: 1.33; 95% CI: 0.76-2.35; P=0.32). High versus low HER3 expression (PFS: 7.1 vs. 8.8 months, HR: 1.11; 95% CI: 0.82-1.50; P=0.50; OS: 19.8 vs. 21.1 months, HR: 0.95; 95% CI: 0.70-1.30; P=0.75) and high compared with low HER2/neu expression (PFS: 7.7 vs. 8.0 months, HR: 1.07; 95% CI: 0.71-1.60; P=0.75; OS: 16.6 vs. 21.1 months, HR: 1.13; 95% CI: 0.75-1.71; P=0.57) did not influence outcome. High NRG1 expression was associated with inferior PFS in the FIRE-1 trial. We did not detect a prognostic impact of HER2/neu and HER3 overexpression in mCRC. The frequency of overexpression was comparable with other studies.

To explore the optimal treatment strategy for patients who harbor sensitive EGFR mutations, a head-to-head study was performed to compare chemotherapy and gefitinib in combination or with either agent alone as first-line therapy, in terms of efficacy and safety. A total of 121 untreated patients with advanced lung adenocarcinoma who harbored sensitive EGFR mutations were randomly assigned to receive gefitinib combined with pemetrexed and carboplatin, pemetrexed plus carboplatin or gefitinib alone. The progression-free survival (PFS) of patients in the combination group (17.5 months, 95% CI, 15.3-19.7) was longer than that of patients in the chemotherapy group (5.7 months, 95% CI, 5.2-6.3) or gefitinib (11.9 months, 95% CI, 9.1-14.6) group. The (hazard ratios) HRs of PFS for the combination group vs. chemotherapy and gefitinib groups were 0.16 (95% CI, 0.09-0.29, p < 0.001) and 0.48 (95% CI, 0.29-0.78, p = 0.003), respectively. The overall response rate (ORR) in the combination therapy group, chemotherapy group and the gefitinib group was 82.5%, 32.5% and 65.9%, respectively. The combinational strategy resulted in longer overall survival (OS) than chemotherapy (HR = 0.46, p = 0.016) or gefitinib (HR = 0.36, p = 0.001) alone. Our finding suggested that treatment with pemetrexed plus carboplatin combined with gefitinib could provide better survival benefits for patients with lung adenocarcinoma harboring sensitive EGFR mutations.

Epidemiological studies have shown that dietary compounds have significant effects on prostate carcinogenesis. Among dietary agents, genistein, the major isoflavone in soybean, is of particular interest because high consumption of soy products has been associated with a low incidence of prostate cancer, suggesting a preventive role of genistein in prostate cancer. In spite of numerous studies to understand the effects of genistein on prostate cancer, the mechanisms of action have not been fully elucidated. We investigated the differences in methylation and gene expression levels of prostate specimens from a clinical trial of genistein supplementation prior to prostatectomy using Illumina HumanMethylation450 and Illumina HumanHT-12 v4 Expression BeadChip Microarrays. The present study was a randomized, placebo-controlled, double-blind clinical trial on Norwegian patients who received 30 mg genistein or placebo capsules daily for 3-6 weeks before prostatectomy. Gene expression changes were validated by quantitative PCR (qPCR). Whole genome methylation and expression profiling identified differentially methylated sites and expressed genes between placebo and genistein groups. Differentially regulated genes were involved in developmental processes, stem cell markers, proliferation and transcriptional regulation. Enrichment analysis suggested overall reduction in MYC activity and increased PTEN activity in genistein-treated patients. These findings highlight the effects of genistein on global changes in gene expression in prostate cancer and its effects on molecular pathways involved in prostate tumorigenesis.

Background: Preclinical evidence indicates that increased insulin-like growth factor receptor-1 (IGF1R) signaling interferes with the action of trastuzumab suggesting a possible mechanism of trastuzumab resistance. Thus, we evaluated IGF1R prevalence, relationship with demographic data, and association with disease-free survival (DFS) of patients randomized to chemotherapy alone (Arm A) or chemotherapy with sequential (Arm B) or concurrent trastuzumab (Arm C) in the prospective phase III HER2+ adjuvant N9831 trial.Experimental Design: IGF1R protein expression was determined in tissue microarray sections (three cores per block; N = 1,197) or in whole tissue sections (WS; N = 537) using IHC (rabbit polyclonal antibody against IGF1R β-subunit). A tumor was considered positive (IGF1R+) if any core or WS had ≥1+ membrane staining in >0% invasive cells. Median follow-up was 8.5 years.Results: Of 1,734 patients, 708 (41%) had IGF1R+ breast tumors. IGF1R+ was associated with younger age (median 48 vs. 51, P = 0.007), estrogen receptor/progesterone receptor positivity (78% vs. 35%, P < 0.001), nodal positivity (89% vs. 83%, P < 0.001), well/intermediate grade (34% vs. 24%, P < 0.001), tumors ≥2 cm (72% vs. 67%, P = 0.02) but not associated with race or tumor histology. IGF1R did not affect DFS within arms. Between Arms A and C, patients with IGF1R+ and IGF1R- tumors had DFS HRs of 0.48 (P ≤ 0.001) and 0.68 (P = 0.009), respectively (Pinteraction = 0.17). Between Arms A and B, patients with IGF1R+ and IGF1R- tumors had DFS HRs of 0.83 (P = 0.25) and 0.69 (P = 0.01), respectively (Pinteraction = 0.42).Conclusions: In contrast to preclinical studies that suggest a decrease in trastuzumab sensitivity in IGF1R+ tumors, our adjuvant data show benefit of adding trastuzumab for patients with either IGF1R+ and IGF1R- breast tumors.

The objective of this study is to perform proteomic analysis of pleomorphic adenoma (PA) in the human parotid gland (PG) with comparison of normal PG. This is an individual prospective randomized controlled trial. This study was performed in a tertiary referral center. Tissue samples of PG and PA were taken after surgical excision of PG from 13 patients. Protein extracts were prepared and protein pools created from the soluble extracts were subjected to 2D-DIGE analysis. Proteins displaying regulation in their abundance were determined and identified using MALDIT-OF/TOF analysis. The identified proteins were subjected to STRING analysis for classification of the proteins based on their biological roles in metabolic pathways. Fifteen proteins, carbonic anhydrase 1, carbonic anhydrase 2, fibrinogen beta chain, alpha-amylase 1, heats hock protein hsp 90-alpha, clusterin, 78 kDa glucose-regulated protein, endoplasmin, alpha-amylase 2b, ATP synthase subunit alpha (mitochondrial), elongation factor 1-gamma, malate dehydrogenase, cytoplasmic, triosephosphate isomerase, receptor of activated protein c kinase 1, and aconitate hydratase, mitochondrial were down-regulated, whereas 11 proteins including ig kappa chain c region, serotransferrin, vimentin, annexin a5, glial fibrillary acidic protein, calreticulin, cartilage oligomeric matrix protein, microfibril-associated glycoprotein 4, 14-3-3 protein epsilon, fibulin-5, and f-box only protein 2 were up-regulated in PA samples in comparison to healthy parotid tissue. This study described the differences observed in protein expression patterns of the PA and normal PG. The results may provide new insights into the pathogenesis and diagnosis of PA in human PG.

Purpose: Translational studies suggest that excess perioperative release of catecholamines and prostaglandins may facilitate metastasis and reduce disease-free survival. This trial tested the combined perioperative blockade of these pathways in breast cancer patients.Experimental Design: In a randomized placebo-controlled biomarker trial, 38 early-stage breast cancer patients received 11 days of perioperative treatment with a β-adrenergic antagonist (propranolol) and a COX-2 inhibitor (etodolac), beginning 5 days before surgery. Excised tumors and sequential blood samples were assessed for prometastatic biomarkers.Results: Drugs were well tolerated with adverse event rates comparable with placebo. Transcriptome profiling of the primary tumor tested a priori hypotheses and indicated that drug treatment significantly (i) decreased epithelial-to-mesenchymal transition, (ii) reduced activity of prometastatic/proinflammatory transcription factors (GATA-1, GATA-2, early-growth-response-3/EGR3, signal transducer and activator of transcription-3/STAT-3), and (iii) decreased tumor-infiltrating monocytes while increasing tumor-infiltrating B cells. Drug treatment also significantly abrogated presurgical increases in serum IL6 and C-reactive protein levels, abrogated perioperative declines in stimulated IL12 and IFNγ production, abrogated postoperative mobilization of CD16- "classical" monocytes, and enhanced expression of CD11a on circulating natural killer cells.Conclusions: Perioperative inhibition of COX-2 and β-adrenergic signaling provides a safe and effective strategy for inhibiting multiple cellular and molecular pathways related to metastasis and disease recurrence in early-stage breast cancer.
