The majority of patients with breast carcinoma receive chemotherapy as a component of multimodality treatment. Over the past decade, it has become increasingly more common to deliver chemotherapy first, but this has raised new questions within all disciplines of cancer management. However, the effect of cytotoxic treatment cannot be predicted on individually specific basis, then identification of tumor characteristics associated with tumor therapeutic response and outcome is then of great clinical interest. We studied 141 patients at Masaryk Memorial Cancer Institute, who received neoadjuvant chemotherapy and/or chemotherapy + radiotherapy (CHT/CHT+RT) between 1994-2002. Tumor samples were taken prior to and after neoadjuvant therapy. We quantified the response to therapy pathologically and determined histological and molecular tumor characteristics (steroid receptors, CEA, Ca 15-3). In addition to therapeutic response as immediate outcome, event free survival (EFS) was examined as more complex primary end-point of the study. Complete remission (CR) has been achieved in 6.5%, partial remission (PR) in 49.6%, stable disease (SD) in 26.2% and progression disease (PD) in 17.7% patients. Patients were divided into two groups according to the result of neoadjuvant therapy--responders (CR+PR+SD, who successfully underwent surgery), and risk group (patients with SD or PD, who could not undergo surgery). Responders to neoadjuvant CHT/CHT+RT regimens reached statistically significant better EFS than non-responders, low tumor size (T2) and stage (II) categories were confirmed as additional predictive factors not only for EFS but for therapeutic response as well. The study primarily examined predictive power of tumor markers as CEA, Ca 15-3, and steroid receptors (ER/PR) and searched for their role in the prospective evaluation of neoadjuvant therapy. We evaluated these factors as potential predictors of EFS, independent in predictive power on therapeutic response to neoadjuvant therapy. Diagnostically valuable cut off points were proposed in ROC analysis for all these markers. Responders to the neoadjuvant therapy with Ca 15-3 <23.0 kU/l, CEA <5.0 mg/l, estrogen receptors (ER) >5.0 fmol/mg or both estrogen /progesterone receptors (ER/PR) positive had statistically significantly better EFS in comparison to patients with Ca 15-3 >23.0 kU/l, CEA >5.0 mg/l, ER <5.0 fmol/mg, or other cases than patients double positive in ER/PR. Marker Ca 15-3 revealed significant predictive power even within the group of non- responders, these patients with Ca 15-3 <23.0 kU/l had better EFS as compared to patients with Ca 15-3 >23.0 kU/l. Tumor size and low stage proved predictive value for immediate response to neoadjuvant therapy. Risk parameters for neoadjuvant therapy were T4, stage III, namely if RT was necessary. Therapeutic response to neoadjuvant therapy was independent on investigated molecular parameters, but there was strong predictive association of Ca 15-3, CEA and ER/PR receptors with event free survival development. Diagnostically valuable cut-off points were proposed and validated for sensitivity and specificity in ROC analysis.

OBJECTIVE: To compare serum levels of hyaluronic acid (HA) between patients with erosive and non-erosive hand osteoarthritis (HOA), and investigate its association with morphological changes and radiographic progression over 2 years. METHODS: Fifty-five women with erosive and 33 women with non-erosive HOA were included in this study. All underwent clinical examination, which included assessment of pain, swelling, deformity and deviation of small hand joints and completed health assessment questionnaires. Serum levels of HA were measured by ELISA. Three-phase bone scintigraphy was performed at baseline. Radiographs of both hands were performed at baseline and after 2 years and scored according Kallman grading scale. RESULTS: Serum levels of HA were significantly higher in patients with erosive than with non-erosive HOA (P<0.01). It correlated significantly with the number of hand joints with deviations and deformities. HA adjusted for age and disease duration significantly correlated with radiographs at baseline and after 2 years in all patients with HOA (r=0.560 and r=0.542, P<0.01 for both correlations). Although there was an association between HA and radiographic score in erosive disease, after adjustment for confounders it remained no longer significant. HA adjusted for confounders correlated significantly with the late phase in all patients with HOA (r=0.412, P<0.01) and in patients with erosive disease (r=0.320, P<0.05). CONCLUSION: HA is increased in patients with erosive HOA and could be proposed as a surrogate marker with a predictive value for further radiographic progression of HOA in general. Further investigation is necessary to confirm these results.

BACKGROUND: Melanoma is the most aggressive skin cancer with ability to recur also after early-stage tumor surgery. The aim was to identify early-stage melanoma patients at high risk of recurrence using liquid biopsy, estimating of mutated BRAF ctDNA and the level of tumor marker S100B in plasma. METHODS: Eighty patients were enrolled in the study. BRAF V600E mutation was determined in FFPE tissue and plasma samples using ultrasensitive ddPCR with pre-amplification. The level of S100B was determined in plasma by immunoassay chemiluminescent method. RESULTS: The best prediction of melanoma recurrence after surgery was observed in patients with combined high level of S100B (S100Bhigh) and ctDNA BRAFV600E (BRAFmut) in preoperative (57.1% vs. 12.5%, p = 0.025) as well as postoperative blood samples (83.3% vs. 14.3%, resp., p = 0.001) in comparison with low S100B and BRAF wild-type. Similarly, patients with preoperative and postoperative S100Bhigh and BRAFmut experienced worse prognosis (DFI p = 0.05, OS p = 0.131 and DFI p = 0.001, OS = 0.001, resp.). CONCLUSION: We observed the benefit of the estimation of combination of S100B and ctDNA BRAFmut in peripheral blood for identification of patients at high risk of recurrence and unfavorable prognosis. SIGNIFICANCE: There is still no general consensus on molecular markers for deciding the appropriateness of adjuvant treatment of early-stage melanoma. We have shown for the first time that the combined determination of the ctDNA BRAFmut oncogene (liquid biopsy) and the high level of tumor marker S100B in pre- and postoperative plasma samples can identify patients with the worst prognosis and the highest risk of tumor recurrence. Therefore, modern adjuvant therapy would be appropriate for these patients with resectable melanoma, regardless of disease stage.

BACKGROUND: Predictive testing is a crucial part of the complete diagnostic process of non-small cell lung cancer (NSCLC) and a necessary requirement in order to determine proper course of treatment. However, the possibilities of testing and the spectrum of examined markers are quickly evolving as a result of the progress in diagnostic and therapeutic possibilities, and as such it is necessary to regularly update the current guidelines to achieve proper standards of care in routine practice. PURPOSE: To provide a complex overview of the current problematics of predictive testing in NSCLC at a molecular level, considering also the evaluation of PD-L1 expression based on the international and national guidelines. To summarize the current state of predictive testing employed in NSCLC in the Czech Republic. CONCLUSION: Predictive testing in NSCLC is a part of routine diagnostic practice; however, as a result of the expanding spectrum of diagnostic and therapeutic possibilities, it is undergoing significant development. The existing method of the sequential testing of individual markers is becoming unsuitable; given the increasing number of potential predictors and complex molecular testing, the use of new generation sequencing appears to represent a more suitable solution. The immunohistochemical evaluation of PD-L1 expression is also a necessary part of predictive testing in NSCLC.

Human thyroid peroxidase (hTPO) is a membrane protein with a key role in the thyroid hormones synthesis. Loss of hTPO was described in malignant tumours of the thyroid gland. hTPO was tested as a marker of malignancy. Immunohistochemical study of hTPO in 321 thyroid lesions (45 malignant tumours, 72 benign tumours, 199 benign non-tumours lesions, and 5 normal thyroid glands) is presented. The sensitivity of hTPO in predicting malignancy in thyroid is 64%, and the specificity is 87%. Thus, hTPO is of limited value in the diagnosis of thyroid malignancy. The authors discuss the role of hTPO as a marker of differentiation.

We aimed to detect the levels of T-lympho-cyte subsets and serum tumour markers in patients with non-small cell lung cancer (NSCLC) before chemotherapy, and to investigate the predictive value of their combined detection for the prognosis of NSCLC patients undergoing chemotherapy. The clinical data of 110 NSCLC patients treated with chemotherapy from January 2019 to February 2021 were analysed retrospectively. All patients were followed up for one year and divided into good prognosis group (surviving cases) and poor prognosis group (deceased cases). The predictive value of T-lymphocyte subsets combined with serum tumour markers for prognosis was analysed. The proportions of patients with tumour-node-metastasis stages III-IV, lymph node metastasis and poor differentiation were higher in the poor prognosis group than those in the good prognosis group (P < 0.05). Cox regression analysis revealed that high expression of CD4+ and CEA represented protective factors for poor prognosis of NSCLC patients undergoing chemotherapy [odds ratio (OR) < 1, P < 0.05], while high expression of CA125 was a risk factor (OR > 1, P < 0.05). All the areas under the receiver operating characteristic curves of single indicator detection (CD4+, CEA and CA125 levels) and their combined detection for prediction of the poor prognosis of NSCLC patients undergoing chemotherapy were > 0.70, which was highest in the case of combined detection. T-lymphocyte subsets and serum tumour markers are closely related to the prognosis of NSCLC patients undergoing chemotherapy, and their combined detection is of high predictive value.

BACKGROUND/AIMS: Protocol biopsies offer new possibilities to predict kidney allograft outcome. The aim of this study was to find clinical, laboratory, morphological and molecular predictors of short-term renal graft survival. METHODS: Three-month protocol kidney graft biopsy was carried out on 257 patients. The real-time RT-PCR was used to identify intragraft mRNA expression of several cytokines and chemokines and predictive statistics was performed to find markers connected with the risk of premature graft failure. RESULTS: Compared to patients with normal morphology at 3 months, patients with subclinical rejection including borderline changes had experienced more frequent (p < 0.001) acute rejections before 3-month biopsy, serum creatinine >or=170 micromol/l (p < 0.01), and higher intrarenal expression of RANTES, IP-10 (p < 0.001), C3, CD3, IgJ (p < 0.01) and CD20 (p < 0.05). There was a significant correlation between subclinical rejection and the occurrence of late acute rejection and graft failure at the first year after transplantation. Moreover, higher RANTES and IP-10 expressions in subclinical rejection predicted graft loss at one year after transplantation in the univariate analysis. CONCLUSIONS: Patients with subclinical rejection including borderline changes in 3-month biopsy and particularly those with higher intrarenal expression of RANTES and IP-10 mRNA were found to be at risk for premature kidney graft loss.

Galectin-3 (gal-3) is lectin which is presumed to interact with extracellular matrix proteins and cell surface glycoproteins in normal and pathophysiological conditions. The expression of gal-3 at the fetal-maternal interface partially overlaps that of gal-1, suggesting that an interplay between them might be important for hypertensive disorders in pregnancy like preeclampsia. The aim of our study was to test the hypothesis whether galectin-3 could be used as a predictive marker for early-onset preeclampsia development. 32 patients with early-onset preeclampsia were examined, mean age 28.8 ± 5.5; and 22 age matched normal pregnancies mean age 28.5 ± 6.0. The enzyme-linked immunosorbent assay (ELISA) was used for measuring serum galectin-3 levels. There were no significant differences between serum levels of galectin-3 in sera of preeclampsia patients compared to normal pregnant women - 14.1 ± 4.77 vs. 15.7 ± 5.95 ng/ml (p>0.05). Serum galectin-3 levels correlated with maternal age (r=0.33; p=0.03) and BMI (body mass index) (r=0.52; p=0.01). Our data suggest that determination of serum galectin-3 levels may not be a useful method for prediction of early-onset preeclampsia. Studies should be aimed to other categories of biomarkers.

INTRODUCTION: Hyperechogenic bowel (HB) occurs in 0.1 to 1.8% of normal pregnancies. In most cases it has no consequence for the foetus, but can be associated with cystic fibrosis (CF), chromosomal defects, genetic syndromes, viral infections, gastrointestinal pathology, missed gravidity, IUGR and preterm labour. OBJECTIVES: Assessment the risk of the foetus having CF or other abnormalities when HB was detected during ultrasound screening in the second trimester of pregnancy in our centre. DESIGN: Retrospective study. SETTING: Department of Obstetrics and Gynecology, Centre of Fetal Medicine and Genetics, KNTB a.s. Zlín. METHODS: Retrospective analysis of 149 cases of HB between 17 to 22 weeks of pregnancy detected from January 2008 to April 2012. HB was evaluated according to its degree of echogenicity (Slotnik/Abuhamed classification), presence or absence of other ultrasound markers and the result of first trimester combined screening result. When stage II or III HB and/or borderline risk in first trimester screening, and presence of other ultrasound markers was detected, amniocentesis (AMC) was performed to investigate the karyotype, mutations in the CFTR gene and presence of viral infections (cytomegalovirus and parvovirus B19). If stage I or II HB and/or negative I. trimester screening and no other ultrasound markers, viral infections and mutations in the CFTR gene were investigated form maternal blood. If positive, paternal blood sampling testing for mutation in the CFTR gene was performed. If a mutation was detected in both parents, AMC was performed. Mutations of the CFTR gene was investigated with a commercial panel of 33 to 50 most common mutations. Postnatally the outcome of neonatal screening for CF(IRT) and any newborns with congenital malformations were ascertained. RESULTS: HB was seen in 149 foetuses, AMC was performed in 94 (63%), and blood sampling in 55 (37%). Two mutations in the CFTR gene associated with a severe form of CF (deltaF508/3849 KBC +10 T) were found in one foetus from the AMC group with stage III HB. The parents decided to terminate the pregnancy. The incidence of HB in our group was 0.7%. In 4 foetuses (2.7%) with stage II HB heterozygous deltaF508 mutation was found, in the rest no mutations were detected. Parents of heterozygous carriers underwent genetic consultation. Postnatal CF screening (IRT level from a heel prick sample) was negative; therefore no further molecular genetic analysis was performed. Infection was detected in three foetuses; one case was managed with intrauterine transfusion and in the other two cases parents decided for termination. Four cases (2.7%) were terminated because of severe congenital anomalies. Minor congenital abnormalities were detected in seven (4.7%) cases. Intrauterine death was detected in three (2%) pregnancies. CONCLUSION: Based on our results, HB can be considered as a significant marker for the risk of CF, especially in HB stages II and III. It also demonstrates the importance of this marker for the risk of other foetal abnormalities.

BACKGROUND: Hyponatremia is a well-known phenomenon in cancer patients. The aim of our retrospective study was to assess the relationship of natremia levels to predict treatment with erlotinib and also to assess the prognosis of patients with hyponatremia. PATIENTS AND METODS: We analyzed data of 544 patients with advanced-stage non-small cell lung cancer (NSCLC) treated with erlotinib. RESULTS: Hyponatremia was measured in 21.5 % of patients before treatment with erlotinib. We found a significant increase in the effectiveness of treatment with erlotinib in patients with normal levels of sodium to hyponatremic patients. Progression-free survival (PFS) and overall survival (OS) were also significantly higher in patients with normal natremia. Multivariate Cox model analysis demonstrated that natremia was an independent factor for PFS and OS. CONSLUSION: We reported hyponatremia not only as a prognostic marker in NSCLC patients but also as predictive marker of erlotinib treatment efficacy, being an independent factor at the present large retrospective study. Its possible effect in clinical practice is bigger thanks the simple possibility of testing of hyponatremia and the low cost of this biomarker.
