Prognostic impact of the cumulative dose and dose intensity of everolimus in patients with pancreatic neuroendocrine tumors

The aim of this work is to assess if cumulative dose (CD) and dose intensity (DI) of everolimus may affect survival of advanced pancreatic neuroendocrine tumors (PNETs) patients. Median OS was 24 months in Group A (with cumulative dose ≤ 3000 mg) while in Group B (with cumulative dose > 3000 mg), it was not reached (HR: 26.9; 95% CI: 11.0–76.7; P < 0.0001). This should prompt efforts to continue everolimus administration in responsive patients up to at least 3000 mg despite delays or temporary interruptions.

Ultrasonography-driven combination antibiotic therapy with tigecycline significantly increases survival among patients with neutropenic enterocolitis following cytarabine-containing chemotherapy for the remission induction of acute myeloid leukemia

Prompt ultrasonography-driven combination antibiotic therapy for NEC improved survival among acute myeloid leukemia (AML) patient. Chemotherapy schedules with robust dosages of cytarabine for AML remission are associated with a high rate of NEC incidence and attributable mortality. Vigorous antibacterial therapy, specifically those also including tigecycline, may be effective in improving 30-day survival rate after NEC onset.

Genetic variants of cell cycle pathway genes predict disease-free survival of hepatocellular carcinoma

Associations between genetic variants of cell cycle pathway genes and prognosis of hepatocellular carcinoma (HCC) remain largely unknown. In this study, we evaluated the associations between 24 potential functional single nucleotide polymorphisms (SNPs) of 16 main cell cycle pathway genes and disease-free survival (DFS) of 271 HCC patients who had undergone radical surgery resection. We identified two SNPs, i.e., SMAD3 rs11556090 A>G and RBL2 rs3929G>C, that may independently or jointly modulate the disease-free survival of HCC patients.

Renal impairment and use of nephrotoxic agents in patients with multiple myeloma in the clinical practice setting in the United States

In this observational study, the prevalence of both renal impairment and chronic kidney disease was high in patients with multiple myeloma, affecting 61% and 50%, respectively, of patients in the OSCER cancer database in the US for the period 2012 to 2015. The onset of renal impairment was rapid after the multiple myeloma diagnosis; however, 40% of these patients nevertheless received concomitant nephrotoxic agents, most of which were intravenous bisphosphonates. As renal impairment is associated with reduced survival and may affect clinical management, preservation of renal function is critical, and non-nephrotoxic alternatives are warranted where possible in managing the multiple myeloma population.

Associations between ABO blood groups and pancreatic ductal adenocarcinoma: influence on resection status and survival

The relationship between ABO blood groups and pancreatic ductal adenocarcinoma was investigated in patients from Western Norway. There was an over-representation of blood group A among patients when compared with healthy blood donors, and this association could be fully attributed to the A1 subgroup. Blood group O was found to be protective, both when blood donors and random hospitalized patients were used as controls. The frequency of blood group O was particularly low among unresected patients, in whom this blood group also associated with better survival.

Impact of postoperative complications on the colorectal cancer survival and recurrence: analyses of pooled individual patients’ data from three large phase III randomized trials

This study assessed the impact of postoperative complications on the colorectal cancer survival and recurrence after curative surgery using pooled individual patients’ data from three large phase III randomized trials. In this study, we found that postoperative complications can worsen the colorectal cancer survival and risk of recurrence. Surgical morbidity must be considered as a stratification factor in future phase III trials evaluating the effects of adjuvant chemotherapy on colorectal cancer.

Prognostic value of Notch receptors in postsurgical patients with hepatitis B virus-related hepatocellular carcinoma

Our study aims to investigate the prognostic value of Notch receptors in postsurgical patients with hepatitis B virus-related hepatocellular carcinoma. Our findings collectively indicate that Notch receptors variants (rs1043996 in Notch3 and rs422951, rs520692, rs3830041 in Notch4) are independent predictive targets for overall survival (OS) in HBV-related HCC patients. Notch3 expression is a potential prognostic biomarker of OS and recurrence-free survival (RFS) prediction in HBV-related HCC patients following surgical treatment.

Early ovariectomy reveals the germline encoding of natural anti-A- and Tn-cross-reactive immunoglobulin M (IgM) arising from developmental O-GalNAc glycosylations. (Germline-encoded natural anti-A/Tn cross-reactive IgM)

Early ovariectomy reveals the germline encoding of natural anti-A- and Tn-cross-reactive immunoglobulin M (IgM) arising from developmental O-GalNAc glycosylations. (Germline-encoded natural anti-A/Tn cross-reactive IgM)

In mouse and man, the complementarity of the nonimmune anti-A/Tn cross-reactive IgM most likely occurs in a process of rapid glycosylations/deglycosylations, called “single cycle event”, which causes the release of an antibody molecule that displays a predetermined breaking point through the hydroxyl (–OH) functional group of terminal serine/threonine residues. The germline encoded anti-Tn cross-reactivity of the anti-A-specific isoagglutinin and the pronounced occurrence of anti-Tn reactivity in plasma from humans with histo (blood) group O(H), could contribute to the potential, currently discussed survival advantage of this group in the overall risk of developing cancer when compared with non-O blood groups.

The prognostic impact of programmed cell death ligand 1 and human leukocyte antigen class I in pancreatic cancer

The expression of PD-L1 did not alter the patients’ prognosis if their tumors were HLA class I low, but it did for those with HLA class I high tumors. These findings suggest that the evaluation of PD-L1 and HLA class I expression is useful to predict the patients’ prognosis and HLA class I should be a new biomarker to select patients who may benefit from anti-PD-1/PD-L1-based immunotherapy.

The prediction models for postoperative overall survival and disease-free survival in patients with breast cancer

This study reports an analysis of prediction models for postoperative overall survival (OS) and disease-free survival (DFS) in patients with breast cancer, in which we incorporated genes we found associated with the postoperative survival into MammaPrint genes, often used to predict prognosis of patients with early-stage breast cancer, and constructed postoperative OS and DFS prediction models using a Cox proportional hazard model. Not only did our models achieve an area of a receiver operating characteristic curve (AUC) of 0.71 and 0.60 on an independent test set, but the KM curves also showed a statistically significant difference between the predicted high- and low-risk groups in both OS (log-rank trend test P = 0.0033) and DFS (log-rank trend test P = 0.00030).

Dual addressing of thymidine synthesis pathways for effective targeting of proliferating melanoma

FdUrd increases mitotic activity in melanoma cells and inhibits pyrimidine de novo synthesis pathway, leading to efficient uptake of salvage thymidine synthesis pathway targeting Auger electron-emitting thymidine analog 123/125I-ITdU. The DNA-incorporated 123/125I-ITdU induces severe DNA damages (double-strand breaks) and consequently cell apoptosis.

Overexpression of the human antigen R suppresses the immediate paradoxical proliferation of melanoma cell subpopulations in response to suboptimal BRAF inhibition

Tumor heterogeneous response of melanoma cells to targeted therapies is limiting their efficacy. In this study, using single-cell mass cytometry, we were able to track within the heterogeneous response of a melanoma BRAFV600-sensitive cell line, the paradoxically proliferating subsets of cells that emerge as an immediate response to suboptimal BRAF inhibition. Moreover, we were able to show that the overexpression of the human antigen R overcomes such immediate heterogeneous response. This study initiates a new avenue to prevent the occurrence of adaptive resistance to targeted therapies.

Comparative molecular profiling of HPV-induced squamous cell carcinomas

The manuscript describes our multiplatform testing and analysis of 743 samples of anal, cervical, oropharyngeal, and vulvar squamous cell carcinomas to identify molecular signatures common to HPV-induced cancers. We specifically focused on biomarkers which may be predictive of treatment efficacy and aid in determining treatment regimens. Examination of 79 biomarkers revealed striking similarities between the different cancers types, including similar rates of oncogene mutation, gene amplification, PD-L1 expression, and MGMT and RRM1 silencing which indicates that treatment protocols may be similarly effective in these different cancers.

In vitro additive antitumor effects of dimethoxycurcumin and 5-fluorouracil in colon cancer cells

Dimethoxycurcumin (DMC) is a kind of lipophilic analog of curcumin, an effective antitumor substance for colon cancer, with great improvement in chemical and metabolic stability. Chemotherapy, represented by 5-fluorouracil (5-Fu), plays a key role in the current management of colon cancer. In this study, we revealed an additive antitumor effect of DMC and 5-Fu in colon cancer cells, which was closely related to induction of apoptosis, stimulation of G0/G1 phase arrest, increasing of ROS production, decreasing of mitochondrial membrane potential, and enhancing of endoplasmic reticulum expansion.

Predictors of BRCA1/2 genetic testing among Black women with breast cancer: a population-based study

Our study identifies predictors of BRCA testing among Black women treated for breast cancer and examines differences between BRCA testers and nontesters. We conducted an analysis of 945 Black women ages 18–64 diagnosed with localized or regional-stage invasive breast cancer in Pennsylvania and Florida between 2007 and 2009. Logistic regression was used to identify predictors of BRCA 1/2 testing. Few (27%) (n = 252) of the participants reported having BRCA testing. In the multivariate analysis, we found that perceived benefits of BRCA testing (predisposing factor) ([OR], 1.16; 95% CI: 1.11–1.21; P < 0.001), income (enabling factor) ([OR], 2.10; 95% CI: 1.16–3.80; P = 0.014), and BRCA mutation risk category (need factor) ([OR], 3.78; 95% CI: 2.31–6.19; P < 0.001) predicted BRCA testing.
