Abstract 4330: Immune checkpoint expression score is an independent prognostic biomarker in resectable non-small cell lung cancer
2015
Abstract BACKGROUND Immune checkpoints blockade, which activate antitumor immunity, has demonstrated promising clinical results in NSCLC. In this study we have investigated the prognostic role of immune checkpoint expression markers and its correlation with immune-cells infiltration and clinico-pathological characteristics in a cohort of resectable NSCLC patients. MATERIAL AND METHODS RNA was isolated from fresh-frozen lung specimens (tumor and normal lung) (n = 178). RTqPCR was performed to analyze the expression of CTLA-4, PD-1 and PD-L1 by the use of hydrolysis probes. Relative gene expression was assessed by Pfaffl formula and normalized by the use of CDKN1B, GUS and ACTB as endogenous …
Association of immune-regulatory (FoxP3+)-T-cell tumor infiltration status with benefit from chemoimmunotherapy with gemcitabine, oxaliplatin, 5-FU/F…
2009
3045 Background: GOLFIG is a novel chemoimmunotherapy regimen, combining gemcitabine, oxaliplatin, 5-FU/FA with immunoadjuvant GM-CSF and aldesleukine, which resulted safe and very active in colon cancer patients. Antitumor activity and immunity feedback to the treatment resulted strictly correlated. The best outcome was observed in patients showing autoimmunity signs, rise in central-memory-T cells, and decline in peripheral and tumor infiltrating immuno-regulatory T (Treg) cells. On these bases, we investigated a possible correlation between Treg tumor infiltration at diagnosis and clinical outcome of these patients. Methods: An immunohistochemistry study was carried out to quantify the …
Gemcitabine, oxaliplatin, levofolinate, 5-fluorouracil, granulocyte-macrophage colony-stimulating factor, and interleukin-2 (GOLFIG) versus FOLFOX ch…

The GOLFIG-2 phase III trial was designed to compare the immunobiological activity and antitumor efficacy of GOLFIG chemoimmunotherapy regimen with standard FOLFOX-4 chemotherapy in frontline treatment of metastatic colorectal cancer (mCRC) patients. This trial was conceived on the basis of previous evidence of antitumor and immunomodulating activity of the GOLFIG regimen in mCRC. GOLFIG-2 is a multicentric open/ label phase III trial (EUDRACT: 2005-003458-81). Chemo-naive mCRC patients were randomized in a 1:1 ratio to receive biweekly standard FOLFOX-4 or GOLFIG [gemcitabine (1000 mg/m 2, day 1); oxaliplatin (85 mg/m2, day 2); levofolinate (100 mg/m2, days 1-2), 5-fluorouracil (5-FU) (400…
Cetuximab plus FOLFOX-4 in untreated patients with advanced colorectal cancer: a Gruppo Oncologico dell'Italia Meridionale Multicenter phase II study.
2010
<i>Objectives:</i> FOLFOX-4 and FOLFIRI are considered equivalent in terms of activity and efficacy as first-line chemotherapy in metastatic colorectal cancer (mCRC). The monoclonal antibody (mAb) cetuximab showed intrinsic activity as a single agent in mCRC and was approved in combination with CPT-11 for patients who failed previous CPT-11-based treatment. The purpose of this phase II study was to evaluate the activity and safety of FOLFOX-4 plus cetuximab in untreated mCRC patients. <i>Methods:</i> Untreated patients with measurable metastatic disease and expressing epidermal growth factor receptor (EGFR) received cetuximab at a loading dose of 400 mg/m<sup>2…
Colorectal Cancer: Metastatic Disease
2021
Most patients diagnosed with metastatic colorectal cancer (mCRC) develop metastases during the disease course after resection of the primary locoregional cancer. To date, the liver represents the most common site of metastatic involvement. Although several different biological and clinical hallmarks exist between the colon and rectum (different embryological origin, anatomy, and molecular biology), mCRC requires similar staging procedures and systemic treatment strategies (first and subsequent lines) in terms of a multimodal approach treatment as a part of a “continuum of care.” Patients affected by oligometastatic disease should undergo an upfront evaluation by a multidisciplinary team for…
FOLFIRI plus cetuximab versus FOLFIRI plus bevacizumab as first-line treatment for patients with metastatic colorectal cancer (FIRE-3): a randomised,…
2014
Summary Background Cetuximab and bevacizumab have both been shown to improve outcomes in patients with metastatic colorectal cancer when added to chemotherapy regimens; however, their comparative effectiveness when partnered with first-line fluorouracil, folinic acid, and irinotecan (FOLFIRI) is unknown. We aimed to compare these agents in patients with KRAS (exon 2) codon 12/13 wild-type metastatic colorectal cancer. Methods In this open-label, randomised, phase 3 trial, we recruited patients aged 18–75 years with stage IV, histologically confirmed colorectal cancer, an Eastern Cooperative Oncology Group (ECOG) performance status of 0–2, an estimated life expectancy of greater than 3 month…
Does neoadjuvant FOLFOX chemotherapy improve the prognosis of high‐risk Stage II and III colon cancers? Three years' follow‐up results of the PRODIGE…
2021
International audience; Aim Neoadjuvant chemotherapy has proven valuable in locally advanced resectable colon cancer (CC) but its effect on oncological outcomes is uncertain. The aim of the present paper was to report 3-year oncological outcomes, representing the secondary endpoints of the PRODIGE 22 trial. Method PRODIGE 22 was a randomized multicentre phase II trial in high-risk T3, T4 and/or N2 CC patients on CT scan. Patients were randomized between 6 months of adjuvant FOLFOX (upfront surgery) or perioperative FOLFOX (four cycles before surgery and eight cycles after; FOLFOX perioperative). In wild-type RAS patients, a third arm testing perioperative FOLFOX-cetuximab was added. The pri…
S-Adenosylmethionine Supplementation May Reduce Cancer-Related Fatigue: A Prospective Evaluation Using the FACIT-F Questionnaire in Colon Cancer Pati…
2021
<b><i>Background:</i></b> Fatigue is a common distressing symptom for patients living with chronic or acute diseases, including liver disorders and cancer (<i>Cancer-Related Fatigue</i>, CRF). Its etiology is multifactorial, and some hypotheses regarding the pathogenesis are summarized, with possible shared mechanisms both in cancer and in chronic liver diseases. A deal of work has investigated the role of a multifunctional molecule in improving symptoms and outcomes in different liver dysfunctions and associated symptoms, including chronic fatigue: S-adenosylmethionine (SAM; AdoMet). The aim of this work is actually to consider its role also in oncologic…
Prognostic Impact of Immune Microenvironment Markers in Tumor and Stroma in Resectable Nsclc
2014
ABSTRACT Aim: Tumor-infiltrating immune cells have been proved to play an important role in tumor progression. In this study we have analyzed the expression of 11 immune related genes in both tumor and stroma samples of resectable NSCLC patients. Methods: In this retrospective study FFPE samples from 117 early-stage NSCLC patients of primary tumor tissue were used. The most representative areas of tumor and tumor stroma of each sample were carefully micro-dissected. RT-PCR using hydrolysis probes (TaqMan, Applied Biosystems) was performed to assess the expression of Treg markers such as: CD127, CD25, FOXP3, CTLA-4, IL-10, TGFB-1, LAG-3, GITR and TNFA as well as CD4 and CD8. Relative gene ex…
EP912 Characterization of the tumour microenvironment in high-grade serous ovarian cancer (HGSOC): prognostic value of the lymphocytic infiltration p…
2019
Introduction/Background Lymphocytic infiltration areas (immunoreactive), frequently found in high-grade serous ovarian cancer (HGSOC), are associated with a better prognosis and increased survival. The cross-talk between tumour cells and lymphocytes conditions the capacity of the immune system (IS) to cope with the tumour in the so-called immune-checkpoints. Therefore, assessing IS-related genes and infiltration patters might provide valuable prognostic biomarkers. Methodology This retrospective study includes 57 samples from patients with HGSOC who underwent cytoreductive surgery at Hospital General (Valencia). Clinical variables, the features of the lymphocytic infiltration (pattern, loca…
