Prognostic Factors for Uterine Sarcoma and Carcinosarcoma: Insights from a 10-Year Follow-Up Study

BACKGROUND Uterine sarcomas and carcinomas are rare tumors and treatment outcomes are far from expected. We investigated the prognostic significance of selected serum biomarkers and the impact of some clinical and tissue factors on overall survival (OS) at 10-year follow-up. MATERIAL AND METHODS The material for analysis was a group of 34 patients with uterine sarcomas and 18 with carcinomas. Immunohistochemistry was performed to determine Ki 67, p53 and ER and PR. Concentrations: CA 125, IL8, VEGF, SFTL1, VEGF R2, sTNFRI and MMP-9 were determined in the serum of patients before treatment and in the control group. RESULTS The most frequently elevated levels observed of sTNF RI in 94% and VEGF in 62%. On the ROC curve analysis, sTNF RI and VEGF concentrations showed the highest sensitivity. Patients with striated cell sarcoma, smooth cell sarcoma and high-grade rhabdomyosarcoma had the worst prognosis. Patient age, FIGO stage and expression of Ki67, p53, ER and PR, CA 125 (p<0.038) and IL-8 (p<0.024) were statistical prognostic factors for OS. However, in multivariate analysis, serum levels of: CA 125 concentration (p<0.045), age (p<0.010) and p53 expression (p<0.014) were found to be significant independent prognostic factors. CONCLUSIONS A 10-year follow-up of patients with uterine sarcoma indicates that age above 60 years at diagnosis and high p53 expression and elevated CA125 levels before treatment can be independent prognostic factors. The high diagnostic sensitivity of sTNF RI and VEGF suggests the possibility of using these biomarkers in the early diagnosis of uterine sarcomas.

Prognostic value of coronary atherosclerosis and CAC score for the risk of chemotherapy-related cardiac dysfunction (CTRCD): The protocol of ANTEC study

BACKGROUND

Cardiological complications of oncological treatment, including the most serious one, heart failure, constitute a significant and still unsolved clinical problem. A history of dyslipidemia and complications of atherosclerosis, including coronary artery disease, are established risk factors for cardiotoxicity in cancer patients. In recent years, a protective effect of statin treatment on the development of heart failure in cancer patients has been observed. This protocol describes a study aiming to assess the prognostic value of coronary atherosclerosis burden and the CAC score on the onset of cardiac dysfunction associated with cancer therapy.

METHODS

ANTEC (Atherosclerosis iN chemoTherapy-rElated Cardiotoxicity) is a single-site, prospective, observational study to evaluate the influence of the coronary atherosclerosis and CAC score assessed by computed tomography on the development of left ventricular systolic dysfunction in cancer patients with at least moderate cardiotoxicity risk. A group of 80 patients diagnosed with cancer prior to high-dose anthracycline chemotherapy (doxorubicin ≥ 240 mg / m2 body weight or epirubicin ≥ 600 mg / m2 body weight), without a history of heart failure and coronary artery disease, will be included in the study. Patient follow-up is planned for 12 months. In all patients, coronary computed tomographic angiography (CCTA) will be performed once at the beginning of the study. The primary endpoint is the onset of cancer therapy-related cardiovascular toxicity, defined as mild, moderate, severe and very severe according to ESC 2022 Cardio-oncology guidelines. During follow up, echocardiography with GLS assessment will be performed every three months. Additionally, new biomarkers of atherosclerosis (IL-6, MPO, TNF-alpha) will be measured every 6 months. The study registration identifier on clinicaltrials.gov is NCT05118178.

IL-1β and IL-6 as predictors of ypN and early response to neoadjuvant chemotherapy in patients with locally advanced GC and GEJ cancer

454

Background: Perioperative chemotherapy remains a standard of care in locally advanced gastric cancer. About 10-15% patients do not respond to such therapy and there are currently no biomarkers which could be used to predict early response to the neoadjuvant treatment. Methods: This prospective biomarker study aimed at identification of serum biomarkers of early response to neoadjuvant chemotherapy. Here we report only the results for serum cytokine assessments. It was an academic, nonrandomized, prospective study, conducted in MSCNRIO. Between January 2018 and November 2019 we analysed 42 patients aged 30-77 (median 63 years, 52.5% male and 47.5% female) with histologically confirmed GC or GEJ cancer qualified by MDT for perioperative FLOT. Exclusion criteria were: inflammatory and autoimmune diseases, other cancers, chronic steroid and immunosuppressive therapy. Blood sample was collected a.c. prior to the administration of cycle one (C1), two (C2) and three (C3) FLOT regimen. Serum levels of IL-1β and IL-6 were measured twice using ELISA. Results: All patients with pre-treatment IL-1β levels above 0.5 ng/ml on the postoperative histopathological report had positive lymph nodes (ypN+). There was a statistically significant difference in the level of IL-1β in the blood serum of patients before the start of treatment in the subgroups ypN0 vs ypN+ vs unresectable tumor (p = 0.003), ypN0 vs ypN+ (p = 0.002) as well as ypN+ vs unresectable tumor (p = 0.075). There was a trend for change in IL-1β level between cycles C1 and C3 in the ypN0 vs ypN+ subgroups (p = 0.056). The difference in IL-1β level before C1 between the groups TGR-G1-2/ypN0 vs TGR-G1-2/ypN+ vs TGR-G3/ypN0 vs TGR-G3/ypN+ was statistically significant (p = 0.017). The difference in IL-6 level between C3 and C1 in the subgroups TGR-G1-2/ypN0 vs TGR-G1-2 / ypN + vs TGR-G3 / ypN0 vs TGR-G3 / ypN + vs unresectable tumor was statistically significant (p = 0.009). Among the analyzed factors, only the difference in serum IL-6 level between C3 and C1 may be a predictor of ypN+ response to preoperative FLOT regimen. Among ypN0 patients, 76% had an IL-6 difference between C3 and C1> 1.1, i.e. C3 greater than C1 by at least 1.1 (specificity), and among ypN+ patients 83% had an IL-6 difference between C3 and C1 <1.1 (specificity). Conclusions: Low IL-1β levels before starting treatment is a prognostic factor while an early decrease in IL-6 could be considered a predictive marker of response to FLOT.

Clinical value of kinase Aurora-A serum level determination in patients with breast cancer qualified for neoadjuvant chemotherapy: Pilot study

e12627

Background: Aurora A (AURKA) is serine/threonine kinase that plays a regulatory role in mitosis and multiple signaling pathways. Overexpression of AURKA has been found in many solid tumors including breast cancer. It also has been found to be a prognostic marker indicating resistance to taxane treatment and poor prognosis in ER positive breast cancer. The aim of this study is to assess clinical value of Aurora-A serum level determination in patients with breast cancer qualified for neoadjuvant chemotherapy. Methods: 60 patients with confirmed breast cancer before treatment were qualified for the study, aged 31-77 (median 52 years), including 30 premnopausal and 30 pomenopausal. The control group consisted of 30 healthy women aged 20-80 (median 53 years). Clinical and pathological features were determined in a selected group of patients with breast cancer who subsequently underwent preoperative chemotherapy, i.e. tumor size (T), lymph node status (N), presence of distant metastases (M), estrogen receptor status (ER) and progesterone (PgR), HER2 receptors and Ki 67 proliferative index. The blood serum of the examined patients and healthy women was determined by the enzyme-linked ELISA method in doublets of the AURKA biomarker concentration. Mann-Whitney test and ROC curve analysis were used for statistical calculations. Results: No significant differences were found between the concentrations of AURKA in breast cancer patients and in the control group. In both analyzed groups there were no significant differences in biomarker levels depending on the menopausal status. When assessing the relationship between AURKA concentrations and clinical-pathological features, significant differences were found depending on the state of the lymph nodes (N0 vs N1 + N2) (p = 0.006). There was no correlation between the concentrations of the tested biomarker and the tumor size (T), the state of receptors and the Ki67 index. In patients with a lack of receptors (triple negative vs others), higher levels of Aurora A (p = 0.06) in the blood serum were observed at the level of the statistical trend. Conclusions: The preliminary results obtained indicate the potential usefulness of determining the concentration of the new biomarker Aurora A in the blood serum of patients with breast cancer. The research is continuing.

Prognostic value of chromogranin A in patients with GET/NEN in the pancreas and the small intestine

The aim of this study was to evaluate the clinical usefulness of the chromogranin A (CgA) determination in patients with neuroendocrine neoplasms (NENs) of the digestive system and to analyse the association between concentration of the marker and progression-free survival (PFS) and overall survival (OS). Serum concentrations of CgA were determined before the treatment in 131 patients with NENs, including patients with tumours located in the pancreas, the small intestine, caecum, appendix and in the colon. No significant associations were identified in CgA concentrations between the control group and patients with NENs in appendix and colon. In patients with NENs of the pancreas and NENs of the small intestine and caecum, increased CgA levels were associated with lymph node involvement, distant metastases and a baseline liver involvement. Analyses revealed significantly higher CgA concentrations in patients with active disease compared to those without symptoms of NEN. In patients with NENs of the pancreas, CgA concentration was correlated with tumour grade and Ki67. Significantly higher CgA levels were also found in patients who died compared to those who lived. Analyses of PFS and OS revealed that CgA concentration was not a prognostic factor in patients with NENs of the pancreas. In patients with NENs of the small intestine and caecum, increased CgA concentrations are independent, poor prognostic factors for both PFS and OS. In conclusion, in patients with NENs in pancreas, CgA levels are associated with disease progression, while in patients with NENs in small intestine and caecum, its concentration is a predictive indicator for PFS and OS.

Serum markers in early-stage and locally advanced melanoma

The identification of prognostic factors in cutaneous melanoma allows choosing the most effective treatment, especially in group of patients with locoregional disease. Markers related to carcinogenesis and angiogenesis in particular have effect on the course of the disease. The aim of this study was to evaluate clinical utility of vascular endothelial growth factor (VEGF), matrix metalloproteinase 2 (MMP-2), MMP-9, tissue inhibitors of metalloproteinase 1 (TIMP-1), and YKL-40 in serum of melanoma patients at pathological stages I-III. We included 148 adult patients with melanoma. The median follow-up was 40 months. Disease recurrence was observed in 43 patients; 3-year disease-free survival (DFS) rate was 71.7%; 35 patients died; and the 3-year overall survival (OS) rate was 85%. Concentrations of VEGF, MMP-2, MMP-9, TIMP-1, and YKL-40 were measured by ELISA kits. VEGF, MMP-9, TIMP-1, and YKL-40 were significantly higher in group of patients than in controls. Increased concentrations of TIMP-1 were related to patient survival, which in the group of lower and increased TIMP-1, disease-free survival amounted to 81 vs. 61% (p = 0.014) and overall survival -88 vs. 82% (p = 0.050), respectively. An increased concentration of YKL-40 was observed in 59% of patients with ulceration and in 26% of patients without ulceration (p = 0.012). We have found a clinically significant correlation between YKL-40 and MMP-9 (rho = 0.363; p = 0.004) as well as YKL-40 and VEGF (rho = 0.306; p = 0.018). In melanoma patients at stages I-III, the high concentrations of TIMP-1 in serum predicted adverse prognosis. YKL-40 was associated with ulceration of primary tumor, which is a very important prognostic factor.

[The prognostic role of clinical factors, VEGF, IL-8 and sTNF-R1 in cutaneous melanomas at locoregional stage]

The treatment results of patients with locoregional melanoma are still not satisfactory - up to 50% of patients experience recurrence and (or) disease dissemination. The aim of the study was to assess the prognostic value of clinical factors and serum cytokines of patients with cutaneous melanoma in locoregional stage.

MATERIAL AND METHODS

149 patients at stage I-III according AJCC treated between 2007-2010 were included. Pre-surgery serum levels of VEGF IL-8 and sTNF-R1 were analyzed by ELISA method in 74 melanoma patients and 50 healthy controls. The median follow-up time was 16 months (range: 1-81 months).

RESULTS

The most important factors influencing the disease-free survival (DFS) are: staging system according to AJCC) (p < 0.001), regional nodal stage (pN) (p < 0.001), primary tumor (Breslow) thickness (pT) (p = 0.013) and melanoma ulceration (p = 0.004). The serum levels of selected cytokines were significantly higher in melanoma patients than in healthy volunteers (VEGF, p < 0.001; sTNF-R1, p < 0.001; IL-8, p = 0.001). There were no significant relationships between level of cytokine, recurrence or clinical/pathological parameters.

CONCLUSIONS

The AJCC staging system gives the most accurate insight into prognosis of melanoma patients at locoregional stage after primary therapy. Cytokine serum profile in melanoma patients at locoregional stage has limited value for predicting tumor burden and treatment outcomes.

The value of tumor marker and cytokine analysis for the assessment of regional lymph node status in cervical cancer patients

The aim of the study was to evaluate the utility of the measurements of the circulating tumor markers, squamous cell carcinoma antigen (SCCA), CA125, carcinoembryonic antigen (CEA), cytokeratin fragment 19 (CYFRA 21.1), and the cytokines, interleukin-6 and vascular endothelial growth factor (VEGF), to estimate regional lymph node involvement in patients with cervical cancer. The study comprised 182 untreated patients with cervical cancer. The regional lymph node status was assessed either by the postsurgical histopathologic examination or by the computed tomography (CT). Concentrations of SCCA, CEA, and CA125 were determined using the Abbott Instruments system, of CYFRA 21.1 by the Roche kits, and of IL-6 and VEGF by the ELISA of R&D Systems (Minneapolis, MN). For the statistical analyses, Mann-Whitney U test and chi(2) test were applied. Serum levels of SCCA, CEA, CA125, CYFRA 21.1, IL-6, and VEGF were measured in patients with specified pelvic and para-aortic lymph node status. SCCA, CA125, and IL-6 levels were found to be significantly higher in patients with lymph node metastases than in those with no lymph node involvement. Also, the percentage of patients with simultaneously elevated concentrations of SCCA and CA125 or SCCA and IL-6 differed depending on the lymph node status and was significantly higher in the series of patients with lymph node metastases. Simultaneous assessment of serum levels of SCCA and CA125 or SCCA and IL-6 in patients with cervical cancer may be useful for the regional lymph node evaluation, especially in patients with advanced stages, when the lymph nodes are examined only by CT, with no histologic confirmation.

Clinical significance of serum cytokine measurements in untreated colorectal cancer patients: soluble tumor necrosis factor receptor type I--an independent prognostic factor

The aim of this study was to exploit the potential clinical use of circulating cytokine measurements in colorectal cancer (CRC) patients. The levels of cytokines and cytokine receptors were assessed by ELISA in the sera of 50 healthy volunteers and 157 patients with previously untreated CRC and then related to clinicopathological features and prognosis. All tumors were verified histologically as colorectal adenocarcinomas and staged according to TNM classification. The levels of circulating interleukin (IL)-6, IL-8, macrophage colony-stimulating factor (M-CSF) and interleukin 1 receptor antagonist (IL-1ra) significantly increased with the clinical stage of CRC, and the levels of IL-6, soluble tumor necrosis factor (sTNF) receptor type I (RI), soluble interleukin 2 receptor alpha and TNFalpha with tumor grade, while IL-6, IL-8, M-CSF, IL-1ra and sTNF RI levels significantly rose with bowel wall invasion. None of the cytokine or soluble cytokine receptor levels were influenced by age, gender and colon versus rectum localization. sTNF RI, IL-8, IL-6 and vascular endothelial growth factor measurements demonstrated the highest diagnostic sensitivity. sTNF RI was found elevated in the greatest percentage of all CRC patients, in the greatest proportion of stage I patients and presented the best diagnostic sensitivity. In addition, the sTNF RI level strongly correlated with tumor grade and invasion and proved to be an independent prognostic factor.

CRP, TNF-alpha, IL-1ra, IL-6, IL-8 and IL-10 in blood serum of colorectal cancer patients

Blood serum cytokines: TNFalpha, IL-1ra, IL-6, IL-8, IL-10 as well as CRP were investigated in patients with colorectal cancer, prior treatment and 1, 10 and 42 days after surgery. There was an increase of the levels of CRP, IL-6 and IL-10 in most patients 24 hours after surgery. The levels of IL-1ra were elevated in patients in stage C and in several patients in stage B of the disease and there was a decrease of circulating TNFalpha in stage B patients. On day 10 and 42 after surgery, the levels of cytokines followed various patterns.
