First results for resetting the antitumor immune response by immune corrective surgery in colon cancer.
1998
BACKGROUND: A critical step for cancer recurrence is the failure of the cellular immune response. It is suspected that chronic humoral immune responses against some tumor-associated antigens (TAA) can contribute to that failure. METHODS: In this study, we tested the ability of an immune corrective surgical procedure to prevent recurrences of colon cancer in stages I, II, and III. Radiolabeled anti-TAG antibodies injected intravenously become concentrated on TAG-72 immune complexes presented by follicular dendritic cells, which are responsible for the persistent humoral response against TAG-72 TAA. Using a hand-held gamma probe, we can intraoperatively detect and remove lymph nodes involved …

Immune cells in colorectal cancer: prognostic relevance and therapeutic strategies.
2008
During the last two decades, considerable efforts have been made to improve the prevention, early diagnosis and therapy of colorectal cancer by gaining enhanced insights into disease-specific pathogenesis. Along these lines, tumor-infiltrating immune cells turned out to be critical indicators for an efficient antitumor immune response and the number and type of tumor-infiltrating immune cells determined the resulting tumor prognosis. This review aims to describe the prognostic relevance of the different subsets of tumor-infiltrating immune cells and highlights their specific function in the complex process of immune system-mediated rejection of colorectal cancer cells. Considering the clini…
Prognostic factors for progression-free and overall survival in advanced biliary tract cancer
2015
BACKGROUND: Biliary tract cancer is an uncommon cancer with a poor outcome. We assembled data from the National Cancer Research Institute (UK) ABC-02 study and 10 international studies to determine prognostic outcome characteristics for patients with advanced disease.METHODS: Multivariable analyses of the final dataset from the ABC-02 study were carried out. All variables were simultaneously included in a Cox proportional hazards model, and backward elimination was used to produce the final model (using a significance level of 10%), in which the selected variables were associated independently with outcome. This score was validated externally by receiver operating curve (ROC) analysis using…
EndoPredict improves the prognostic classification derived from common clinical guidelines in ER-positive, HER2-negative early breast cancer
2012
Background In early estrogen receptor (ER)-positive/HER2-negative breast cancer, the decision to administer chemotherapy is largely based on prognostic criteria. The combined molecular/clinical EndoPredict test (EPclin) has been validated to accurately assess prognosis in this population. In this study, the clinical relevance of EPclin in relation to well-established clinical guidelines is assessed. Patients and methods We assigned risk groups to 1702 ER-positive/HER2-negative postmenopausal women from two large phase III trials treated only with endocrine therapy. Prognosis was assigned according to National Comprehensive Cancer Center Network-, German S3-, St Gallen guidelines and the EPc…
Immune cell score, PD-L1 expression and prognosis in esophageal cancer.
2021
Esophageal cancer (EC) is the ninth most common cancer worldwide and the sixth leading cause of cancer death [1]. Despite improvements in the treatment of EC, the general outcome remains poor [2–4]...
Prognostic implications of extranodal extension in node-positive squamous cell carcinoma of the vulva: A systematic review and meta-analysis
2016
Squamous cell carcinoma (SCC) of the vulva is the fourth most common gynecological cancer, usually staged with the TNM or FIGO systems. Since 2009, FIGO staging has taken the extranodal extension (ENE) of lymph node metastases into account. ENE is defined as the spread of a lymph node metastasis into surrounding soft tissue. Although the TNM and FIGO systems acknowledge the importance of ENE in SCC, no comprehensive studies have analyzed the prognostic impact of this parameter. We therefore queried the PubMed and SCOPUS databases from their inception up until 04/01/2015, adopting no language restrictions: all prospective studies reporting on prognostic parameters in patients with vulvar SCC…
Diagnostic and prognostic value of three micrornas in environmental asbestiform fibers-associated malignant mesothelioma
2021
Fluoro-edenite (FE) is an asbestiform fiber identified in Biancavilla (Sicily, Italy). Environmental exposure to FE has been associated with a higher incidence of malignant mesothelioma (MM). The present study aimed to validate the predicted diagnostic significance of hsa-miR-323a-3p, hsa-miR-101-3p, and hsa-miR-20b-5p on a subset of MM patients exposed to FE and matched with healthy controls. For this purpose, MM tissues vs. nonmalignant pleura tissues were analyzed through droplet digital PCR (ddPCR) to evaluate differences in the expression levels of the selected miRNAs and their MM diagnostic potential. In addition, further computational analysis has been performed to establish the corr…
Prognostic value of Thyroid Transcription Factor-1 expression in lung adenocarcinoma in patients treated with anti PD-1/PD-L1.
2021
ABSTRACT Anti-PD1/PD-L1-directed immune checkpoint inhibitors are game changers in advanced non-small-cell lung cancer, but biomarkers are lacking. The aim of our study was to find clinically relevant biomarkers of the efficacy of ICI in non-squamous NSCLC. We conducted a retrospective study of patients receiving ICI for advanced non squamous NSCLC in two cohorts. For a subset of patients, RNAseq data were generated on tumor biopsy taken before ICI. The primary end point was progression-free survival under ICI. Secondary end point was overall survival from ICI initiation. In the cohort, we studied 231 patients. Clinico-pathological characteristics included KRAS mutant status (n = 88), TTF1-…
E-Cadherin gene expression in oral cancer: Clinical and prospective data
2019
Background Low protein expression of E-cadherin in oral squamous cell carcinoma (OSCC) has been associated with clinical and histopathological traits such as metastases, recurrence, low survival and poor tumor differentiation, and it is considered a high-risk marker of malignancy. However, it is still unknown whether low expression of E-cadherin is also present at the mRNA level in OSCC cases. Objective: The aim of this study was to compare E-cadherin mRNA expression in OSCC patients and controls and to correlate the expression with clinical and prospective characteristics. Material and Methods Forty patients and 40 controls were enrolled. E-cadherin mRNA expression was evaluated by quantit…
