Abstract
INTRODUCTION Treatment selection tools are needed to enhance the efficacy of targeted treatment in patients with solid malignancies. Providing a readout of aberrant signaling pathways and proteolytic events, mass spectrometry-based (MS-based) peptidomics enables identification of predictive biomarkers, whereas the serum or plasma peptidome may provide easily accessible signatures associated with response to treatment. In this systematic review, we evaluate MS-based peptide profiling in blood for prompt clinical implementation. METHODS PubMed and Embase were searched for studies using a syntax based on the following hierarchy: (a) blood-based matrix-assisted or surface-enhanced laser desorption/ionization time-of-flight MS peptide profiling (b) in patients with solid malignancies (c) prior to initiation of any treatment modality, (d) with availability of outcome data. RESULTS Thirty-eight studies were eligible for review; the majority were performed in patients with non-small cell lung cancer (NSCLC). Median classification prediction accuracy was 80% (range: 66%-93%) in 11 models from 14 studies reporting an MS-based classification model. A pooled analysis of 9 NSCLC studies revealed clinically significant median progression-free survival in patients classified as "poor outcome" and "good outcome" of 2.0 ± 1.06 months and 4.6 ± 1.60 months, respectively; median overall survival was also clinically significant at 4.01 ± 1.60 months and 10.52 ± 3.49 months, respectively. CONCLUSION Pretreatment MS-based serum and plasma peptidomics have shown promising results for prediction of treatment outcome in patients with solid tumors. Limited sample sizes and absence of signature validation in many studies have prohibited clinical implementation thus far. Our pooled analysis and recent results from the PROSE study indicate that this profiling approach enables treatment selection, but additional prospective studies are warranted.

Abstract
Neural tube defects (NTDs) are common birth defects, whose specific biomarkers are needed. The purpose of this pilot study is to determine whether protein profiling in NTD-mothers differ from normal controls using SELDI-TOF-MS. ProteinChip Biomarker System was used to evaluate 82 maternal serum samples, 78 urine samples and 76 amniotic fluid samples. The validity of classification tree was then challenged with a blind test set including another 20 NTD-mothers and 18 controls in serum samples, and another 19 NTD-mothers and 17 controls in urine samples, and another 20 NTD-mothers and 17 controls in amniotic fluid samples. Eight proteins detected in serum samples were up-regulated and four proteins were down-regulated in the NTD group. Four proteins detected in urine samples were up-regulated and one protein was down-regulated in the NTD group. Six proteins detected in amniotic fluid samples were up-regulated and one protein was down-regulated in the NTD group. The classification tree for serum samples separated NTDs from healthy individuals, achieving a sensitivity of 91% and a specificity of 97% in the training set, and achieving a sensitivity of 90% and a specificity of 97% and a positive predictive value of 95% in the test set. The classification tree for urine samples separated NTDs from controls, achieving a sensitivity of 95% and a specificity of 94% in the training set, and achieving a sensitivity of 89% and a specificity of 82% and a positive predictive value of 85% in the test set. The classification tree for amniotic fluid samples separated NTDs from controls, achieving a sensitivity of 93% and a specificity of 89% in the training set, and achieving a sensitivity of 90% and a specificity of 88% and a positive predictive value of 90% in the test set. These suggest that SELDI-TOF-MS is an additional method for NTDs pregnancies detection.

Abstract
BACKGROUND Recent studies have suggested a regulatory role for some of the metabolites derived from oxidative stress in breast cancer. In this way, cancer-induced oxidative changes could modify the breast environment and potentially trigger systemic responses that may affect disease prognosis and recurrence. In this study, we investigated the systemic oxidative profile of women with early breast cancer bearing the primary tumor and after tumor withdrawal, and its long-term implications. PATIENTS AND METHODS Plasma samples were collected at diagnosis, and the systemic oxidative profile was determined by evaluating the lipid peroxidation, total antioxidant capacity of plasma (TRAP), malondialdehyde (MDA), protein carbonylation, and hydroperoxides. Nitric oxide, vascular endothelial growth factor (VEGF), and tumor necrosis factor alpha (TNF-α) levels were further measured. We also evaluated the impact of the oxidative profiling at diagnosis on disease recurrence in a 5-year follow-up. RESULTS Enhanced oxidative stress was detected in patients bearing the primary tumors, characterized by high lipid peroxidation, TRAP consumption, high carbonyl content, and elevated VEGF and TNF-α levels. After tumor removal, the systemic oxidative status presented attenuation in lipid peroxidation, MDA, VEGF, and TNF-α. The 5-year recurrence analysis indicated that all patients who recidivated presented high levels of lipid peroxidation measured by chemiluminescence at diagnosis. CONCLUSIONS Our data suggest that the presence of the primary tumor is indicative of the systemic pro-oxidant status of breast cancer and demonstrates a role for lipid peroxidation in disease recurrence, highlighting the need for a metabolic follow-up of patients with cancer at diagnosis before tumor removal.

Abstract
Although the survival of breast cancer (BC) patients has increased over the last two decades due to improved screening programs and postoperative adjuvant systemic therapies, many patients die from metastatic relapse. Current biomarkers used in the clinic are not useful for the early detection of BC, or monitoring its progression, and have limited value in predicting response to treatment. The development of proteomic techniques has sparked new searches for novel protein markers for many diseases including BC. Proteomic techniques allow for a high-throughput analysis of samples with the visualization and quantification of thousands of potential protein and peptide markers. Human urine is one of the most interesting and useful biofluids for routine testing and provides an excellent resource for the discovery of novel biomarkers, with the advantage over tissue biopsy samples due to the ease and less invasive nature of collection. In this review, we summarize the results from studies where urine was used as a source for BC biomarker research and discuss urine sample preparation, its advantage, challenges, and limitation. We focus on the gel-based proteomic approaches as well as the recent development of quantitative techniques in BC urine biomarker detection. Finally, the future use of modern proteomic techniques in BC biomarker identification will be discussed.

Abstract
UNLABELLED Gross cystic disease (GCDB) is a breast benign condition predisposing to breast cancer. Cryopreserved sera from GCDB patients, some of whom later developed a cancer (cases), were studied to identify potential risk markers. A MALDI-TOF mass spectrometry analysis found several complement C3f fragments having a significant increased abundance in cases compared to controls. After multivariate analysis, the full-length form of C3f maintained a predictive value of breast cancer risk. Higher levels of C3f in the serum of women affected by a benign condition like GCDB thus appears to be correlated to the development of breast cancer even 20 years later. BIOLOGICAL SIGNIFICANCE Increased complement system activation has been found in the sera of women affected by GCDB who developed a breast cancer, even twenty or more years later. C3f may predict an increased breast cancer risk in the healthy population and in women affected by predisposing conditions.

Abstract
Background Breast cancer is one of the most common cancers in the world, and the
identification of biomarkers for the early detection of breast cancer is a
relevant target. The present study aims to determine serum peptidome patterns for
screening of breast cancer. Methods The present work focused on the serum proteomic analysis of 36 healthy volunteers
and 37 breast cancer patients using a ClinProt Kit combined with mass spectrometry
(MS). This approach allows the determination of peptidome patterns that are able
to differentiate the studied populations. An independent group of sera (36 healthy
volunteers and 37 breast cancer patients) was used to verify the diagnostic
capabilities of the peptidome patterns blindly. An immunoassay method was used to
determine the serum mucin 1 (CA15-3) of validation group samples. Results Support Vector Machine (SVM) Algorithm was used to construct the peptidome
patterns for the identification of breast cancer from the healthy volunteers.
Three of the identified peaks at m/z 698, 720 and 1866 were used to construct the
peptidome patterns with 91.78% accuracy. Furthermore, the peptidome patterns could
differentiate the validation group achieving a sensitivity of 91.89% (34/37) and a
specitivity of 91.67% (33/36) (> CA 15–3,
P < 0.05). Conclusions These results suggest that the ClinProt Kit combined with MS shows great
potentiality for the diagnosis of breast cancer. Virtual slides The virtual slide(s) for this article can be found here:
