Highlights of the EORTC St. Gallen International Expert Consensus on the primary therapy of gastric, gastroesophageal and oesophageal cancer - differ…

2012

The 1st St. Gallen EORTC Gastrointestinal Cancer Conference 2012 Expert Panel clearly differentiated treatment and staging recommendations for the various gastroesophageal cancers. For locally advanced gastric cancer (>= PT3N+), the preferred treatment modality was pre- and postoperative chemotherapy. The majority of panel members would also treat T2N+ or even T2N0 tumours with a similar approach mainly because pretherapeutic staging was considered highly unreliable. It was agreed that adenocarcinoma of the gastroesophageal junction (AEG) is classified best according to Siewert et al. Preoperative radiochemotherapy (RCT) is the preferred treatment for AEG type I and II tumours. For AEG type…

The importance of extranodal extension in metastatic head and neck squamous cell carcinoma, in the light of the new AJCC cancer staging system

2017

POWER: An open-label, randomized phase III trial of cisplatin and 5-FU with or without panitumumab (P) for patients (pts) with nonresectable, advance…

2013

TPS4158 Background: More than 50% of pts with esophageal cancer have locally advanced or metastatic disease at the time of initial diagnosis. For this group chemotherapy is increasingly used intending local and distant tumor control, improvement of quality of life (QoL) and longer survival. Previous data suggested that EGFR-targeting antibodies may be safely combined with cisplatin and 5-FU, and in addition may increase the efficacy of the standard cisplatin/5-FU regimen [Lorenzen et al, Ann Oncol2009; 20(10): 1667-1673]. Methods: In this open-label, randomized (1:1), multicenter, multinational phase III trial pts with nonresectable, advanced or metastatic ESCC, not eligible for definitive…

Evaluation of a combined triple method to detect causative HPV in oral and oropharyngeal squamous cell carcinomas: p16 Immunohistochemistry, Consensu…

2012

Abstract Background Recent emerging evidences identify Human Papillomavirus (HPV) related Head and Neck squamous cell carcinomas (HN-SCCs) as a separate subgroup among Head and Neck Cancers with different epidemiology, histopathological characteristics, therapeutic response to chemo-radiation treatment and clinical outcome. However, there is not a worldwide consensus on the methods to be used in clinical practice. The endpoint of this study was to demonstrate the reliability of a triple method which combines evaluation of: 1. p16 protein expression by immunohistochemistry (p16-IHC); 2. HPV-DNA genotyping by consensus HPV-DNA PCR methods (Consensus PCR); and 3 viral integration into the host…

Human papillomavirus genotype attribution in invasive cervical cancer: a retrospective cross-sectional worldwide study.

2010

Summary Background Knowledge about the distribution of human papillomavirus (HPV) genotypes in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. We aimed to provide novel and comprehensive data about the worldwide genotype distribution in patients with invasive cervical cancer. Methods Paraffin-embedded samples of histologically confirmed cases of invasive cervical cancer were collected from 38 countries in Europe, North America, central South America, Africa, Asia, and Oceania. Inclusion criteria were a pathological confirmation of a primary invasive cervical cancer of epithelial origin in the tissue sample selected for analysis of HPV DNA, and informa…

Using Cox's proportional hazards model for prognostication in carcinoma of the upper aero-digestive tract.

1992

One of the major short comings of the traditional TNM system is its limited potential for prognostication. With the development of multifactorial analysis techniques, such as Cox's proportional hazards model, it has become possible to simultaneously evaluate a large number of prognostic variables. Cox's model allows both the identification of prognostically relevant variables and the quantification of their prognostic influence. These characteristics make it a helpful tool for analysis as well as for prognostication. The goal of the present study was to develop a prognostic index for patients with carcinoma of the upper aero-digestive tract which makes use of all prognostically relevant var…

Expression of cell cycle markers and human papillomavirus infection in oral squamous cell carcinoma: use of fuzzy neural networks.

2005

Our aim was to evaluate in oral squamous cell carcinoma (OSCC) the relationship between some cell cycle markers and HPV infection, conditionally to age, gender and certain habits of patients, and to assess the ability of fuzzy neural networks (FNNs) in building up an adequate predictive model based on logic inference rules. Eighteen cases of OSCC were examined by immunohistochemistry for MIB-1, PCNA and survivin expression; presence of HPV DNA was investigated in exfoliated oral mucosa cells by nested PCR (nPCR, MY09-MY11/GP5-GP6), and HPV genotype was determined by direct DNA sequencing. Data were analyzed by traditional statistics (TS) and FNNs. HPV DNA was found in 9/18 OSCCs (50.0 %) wi…

A pilot study of vinorelbine on a weekly schedule in recurrent and/or metastatic squamous cell carcinoma of the head and neck.

1993

Vinorelbine (VNR), 5′-nor-anhydrovinblastine, is a new semi-synthetic vinka alkaloid with selective affinity for mitotic microtubules, which has been shown to be active against several non small cell lung cancer lines in vitro [1]. VNR has been reported to yield a 34.7 % and 20 % overall response rate in patients with squamous cell lung carcinoma and bronchial adenocarcinoma respectively [2]. Moreover, VNR has been shown to be active in advanced breast carcinoma where it may induce a 30–50 % response rate depending on the extent of pretreatment [3]. We tested the activity and toxicity of single agent VNR given on a weekly schedule in a series of patients with recurrent and/or metastatic squ…

P-cadherin expression and survival rate in oral squamous cell carcinoma: an immunohistochemical study

2005

Abstract Background P-cadherin (P-cad) is a transmembrane molecule involved in the cell-cell adhesion and similar to E-cadherin (E-cad), but less investigated in oncology, especially in in vivo studies. Aims of the present study were to assess the prevalence of P-cad expression in oral squamous cell carcinoma (OSCC) and to verify whether P-cad can be considered a marker of prognosis in patients with OSCC. Methods In a retrospective study, a cohort of 67 OSCC patients was investigated for P-cad expression and its cellular localization by immunohistochemistry; some respective healthy margins of resection were similarly investigated as standard controls. After grouping for P-cad expression, OS…

Intracellular signalling via the AKT axis and downstream effectors is active and prognostically significant in cancer of unknown primary (CUP): a stu…

2012

Background: Hypothesising that cancer of unknown primary (CUP) may harbour unique characteristics, we present a translational study of the immunohistochemical expression and clinical correlation of key PTEN/AKT pathway molecules. Patients and methods: We collected 100 paraffin-embedded CUP tissue blocks. We studied using tissue microarrays the expression of PTEN, phospho-AKT, Cyclin D1, p21, phospho-RPS6. From the percentage of staining tumour cells and the literature, we selected cut-offs to classify the expression of each biomolecule. We correlated IHC expression with clinical data. Results: PTEN, pAKT, and pRPS6 showed frequent expression. At univariate analysis, high IHC expression of p…
