Quantitative modeling of clinical, cellular, and extracellular matrix variables suggest prognostic indicators in cancer: a model in neuroblastoma
2014
BACKGROUND: Risk classification and treatment stratification for cancer patients is restricted by our incomplete picture of the complex and unknown interactions between the patient's organism and tumor tissues (transformed cells supported by tumor stroma). Moreover, all clinical factors and laboratory studies used to indicate treatment effectiveness and outcomes are by their nature a simplification of the biological system of cancer, and cannot yet incorporate all possible prognostic indicators. METHODS: A multiparametric analysis on 184 tumor cylinders was performed. To highlight the benefit of integrating digitized medical imaging into this field, we present the results of computational s…
Validation of the AJCC prognostic stage for HER2-positive breast cancer in the ShortHER trial
2019
Abstract Background The 8th edition of the American Joint Committee on Cancer (AJCC) staging has introduced prognostic stage based on anatomic stage combined with biologic factors. We aimed to validate the prognostic stage in HER2-positive breast cancer patients enrolled in the ShortHER trial. Methods The ShortHER trial randomized 1253 HER2-positive patients to 9 weeks or 1 year of adjuvant trastuzumab combined with chemotherapy. Patients were classified according to the anatomic and the prognostic stage. Distant disease-free survival (DDFS) was calculated from randomization to distant relapse or death. Results A total of 1244 patients were included. Compared to anatomic stage, the prognost…
Mesenteric Lymph Node Involvement in Advanced Ovarian Cancer Patients Undergoing Rectosigmoid Resection: Prognostic Role and Clinical Considerations
2014
Background: The aim of this retrospective study was to investigate the incidence of mesenteric lymph node (MLN) involvement, and its prognostic role in advanced ovarian cancer (OC). Methods: OC patients undergoing rectosigmoid resection during primary debulking surgery or interval debulking surgery were recorded. Progression-free survival (PFS) and overall survival were calculated from the date of diagnosis to the date of relapse/progression, death of disease, or the date of last follow-up. Results: MLNs were detected in 102/148 cases (68.9 %); the rate of MLN involvement was 47.0 %. The percentage of metastatic MLNs was higher in cases with >5 MLNs removed compared with cases with ≤5 MLNs …
Sorafenib in Patients with Hepatocellular Carcinoma-Results of the Observational INSIGHT Study.
2016
Abstract Purpose: Sorafenib is the only currently approved systemic therapy for advanced hepatocellular carcinoma (HCC). We aimed to evaluate the safety and efficacy of sorafenib therapy in patients with HCC under real-life conditions regarding patient, tumor characteristics, and any adverse events at study entry and at follow-up visits every 2 to 4 months. Experimental Design: The current INSIGHT study is a noninterventional, prospective, multicenter, observational study performed in 124 sites across Austria and Germany between 2008 and 2014. Results: Median overall survival and time to progression (RECIST) were found to be dependent on baseline Barcelona Clinic Liver Cancer (BCLC) tumor s…
The impact of patient and tumour baseline characteristics on the overall survival of patients with advanced hepatocellular carcinoma treated with sor…
2013
Abstract Background Impact of patient and tumour baseline characteristics on the overall survival is not well characterized in patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib. Aims/methods Univariate/multivariate analyses were conducted to identify retrospectively the impact of baseline characteristics on the survival of 110 patients with advanced HCC treated with sorafenib. Results Median survival of the whole cohort was 6.7 months, median survival in Child-Pugh A, B, C patients was 10.5, 6.1 and 3.0 months and median survival of patients with Barcelona Clinic Liver Cancer (BCLC) stage C/D was 6.8/2.6 months. Presence of ascites, presence of macrovascular invas…
TMPRSS4: a novel tumor prognostic indicator for the stratification of stage IA tumors and a liquid biopsy biomarker for NSCLC patients
2019
Relapse rates in surgically resected non-small-cell lung cancer (NSCLC) patients are between 30% and 45% within five years of diagnosis, which shows the clinical need to identify those patients at high risk of recurrence. The eighth TNM staging system recently refined the classification of NSCLC patients and their associated prognosis, but molecular biomarkers could improve the heterogeneous outcomes found within each stage. Here, using two independent cohorts (MDA and CIMA-CUN) and the eighth TNM classification, we show that TMPRSS4 protein expression is an independent prognostic factor in NSCLC, particularly for patients at stage I: relapse-free survival (RFS) HR, 2.42 (95% CI, 1.47&ndash
Biomarkers for Prognosis and Treatment Response in COVID-19 Patients
2021
During a severe infection such as coronavirus disease 2019 (COVID-19), the level of almost all analytes can change, presenting a correlation with disease severity and survival; however, a biomarker cannot be translated into clinical practice for treatment guidance until it is proven to have a significant impact. Several studies have documented the association between COVID-19 severity and circulating levels of C-reactive protein (CRP) and interleukin-6, and the accuracy of the CRP level in predicting treatment responses has been evaluated. Moreover, promising findings on prothrombin and D-dimer have been reported. However, the clinical usefulness of these biomarkers in COVID-19 is far from …
Survival after curative pelvic exenteration for primary or recurrent cervical cancer a retrospective multicentric study of 167 patients
2014
ObjectiveEvaluate the survival of patients who underwent pelvic exenteration (PE) with curative intent for primary persistent or recurrent cervical cancer.MethodsWe retrospectively investigated 167 consecutive patients, referred to the gynecological oncology units of 4 centers in Germany or Italy, who underwent PE. Data regarding surgery, histology, and oncologic outcomes were collected and statistically evaluated. Survival was determined from the day of exenteration until last follow-up or death.ResultsThe median age was 51 years. Twenty-seven patients (16.2%) underwent PE owing to advanced primary tumors (group A), 34 patients (20.4%) underwent PE owing to persistent cancer after chemothe…
The prevalent KRAS exon 2 c.35 G > A mutation in metastatic colorectal cancer patients: a biomarker of worse prognosis and potential benefit of bevac…
2015
Bevacizumab-containing chemotherapy differently predict increased efficacy in KRAS exon 2 mutant and wild-type metastatic colorectal cancer (MCRC) patients. Mutant compared to wild-type status did not significantly affect progression-free survival (PFS) and overall survival (OS) in patients fit for first line bevacizumab-containing FIr-B/FOx regimen, and after progression. In patients unfit for intensive regimens, mutant status significantly affected PFS, while not OS. Codon 12 KRAS mutations differentially affect GTPase function, and confer worse clinical behaviour. Prognostic relevance of the prevalent c.35 G. >. A KRAS mutation was retrospectively evaluated. Fit c.35 G. >. A mutant patie…
Prognostic value of the immunohistochemical expression of vascular endothelial growth factors in malignant salivary gland neoplasms: a systematic rev…
2020
Background The immunohistochemical expression of vascular endothelial growth factor is a prognostic marker in several cancer types. In salivary gland tumors, the association between vascular endothelial growth factor and prognosis remains unclear. The purpose of this study was to perform a systematic review and meta-analysis to assess whether the immunohistochemical expression of vascular endothelial growth factor in patients with salivary gland neoplasms presents prognostic value. Material and Methods Immunohistochemical studies assessing the predictive value of vascular endothelial growth factor in salivary gland neoplasms were systematically reviewed using PubMed, Scopus, Embase, Cochran…
