Prognostic impact of phosphorylated HER-2 in HER-2+ primary breast cancer.
2011
Abstract Purpose. Tyrosine 1248 is one of the autophosphorylation sites of human epidermal growth factor receptor (HER)-2. We determined the prognostic value of the expression level of tyrosine 1248–phosphorylated HER-2 (pHER-2) in patients with HER-2+ primary breast cancer using a reverse-phase protein array. Patients and Methods. The optimal cutoff value of pHER-2 for segregating disease-free survival (DFS) was determined by receiver operating characteristic (ROC) curve analysis. Five-year DFS for pHER-2 expression level was estimated with the Kaplan-Meier method using both derivation (n = 162) and validation (n = 227) cohorts. Results. Of the 162 patients in the derivation cohort, 26 had…
Effects of p63 expression on survival in oral squamous cell carcinoma
2007
BACKGROUND: P63 is the protein codified by p63 gene, a p53 gene homolog, known for its pivotal role in cell cycle regulation, and involved in the tumor differentiation. Aims of the present study were to assess the frequency and pattern of p63 protein expression in oral squamous cell carcinoma (OSCC) in relation to the main tumour characteristics and to verify whether p63 can be considered a marker of prognosis in patients with OSCC. MATERIAL AND METHODS: In a retrospective study, a cohort of 64 OSCC patients was investigated for p63 protein expression and its cellular localization by immunohistochemistry (monoclonal mouse anti-human p63 protein-clone 4A4). After grouping by p63 expression, …

Exposure to UV radiation and risk of Hodgkin lymphoma: A pooled analysis
2013
Ultraviolet radiation (UVR) exposure has been inversely associated with Hodgkin lymphoma (HL) risk, but only inconsistently, only in a few studies, and without attention to HL heterogeneity. We conducted a pooled analysis of HL risk focusing on type and timing of UVR exposure and on disease subtypes by age, histology, and tumor-cell Epstein-Barr virus (EBV) status. Four case-control studies contributed 1320HLcasesand 6381 controls. We estimated lifetime, adulthood, and childhood UVR exposure and history of sunburn and sunlamp use. We used 2-stage estimation with mixed-effects models and weighted pooled effect estimates by inverse marginal variances. We observed statistically significant inv…
Quality of Life in Patients With Severe Skin Reactions in Course of First-Generation Epidermal Growth Factor Receptor Inhibitors Monoclonal Antibodie…
2021
Background: Metastatic colorectal cancer (mCRC) with wild type expression of RAS and RAF genes can be treated with anti-epidermal growth factor receptor (EGFR) monoclonal antibodies, such as cetuximab, in combination with chemotherapy. Skin toxicity represents the most serious and frequent side effect in these patients. Skin manifestations occur in approximately 80% of patients. In this study, we investigated the consequences on body image and quality of life (QoL) of patients with severe skin toxicity. Methods: One hundred patients were enrolled with mCRC. All patients signed informed consent and completed questionnaires to assess QoL and body discomfort. Toxicity was assessed on Common Te…
Vulvar cancer: a review for dermatologists.
2015
Vulvar malignancies are important tumors of the female reproductive system. They represent a serious health issue with an incidence between 2 and 7 per 100,000 and year. We provide a review about most important cancer entities, i.e., melanoma, squamous cell carcinoma, basal cell carcinoma, neuroendocrine cancer, and skin adnexal malignancies. Squamous cell carcinoma is the most common vulvar malignancy that can develop from vulvar intraepithelial neoplasia or de novo. Basal cell carcinoma represents only 2 % of all vulvar cancers. Melanoma of the vulva exists in two major types—superficial spreading and acral lentiginous. A special feature is the occurrence of multiple vulvar melanomas. Of …
Physical forces in blister formation. The role of colloid osmotic pressure and of total osmolality in fluid migration into the rising blister.
1978
The physical forces operative in the fluid migration from the interstitial spaces into the blister cleft have not been directly measured until now. The colloid osmotic pressure and the total osmolality were determined in suction blister fluid after mild suction blister production by a modified “Dermovac” and in blister fluid of patients with dermatitis herpetiformis, bullous allergic contact dermatitis and pemphigus vulgaris and in the sera of healthy persons. The colloid osmotic pressure was measured by means of a recently developed osmometer with a semipermeable membrane between 2 chambers, one of them filled with Ringer solution, the other with the blister fluid or serum sample. The nega…
Cuticular hydrocarbon profiles in Blattella germanica: effects of halofenozide, boric acid and benfuracarb
2006
1379-1176 (Print) Journal Article; In order to complete previous studies conducted on Blattella germanica, three insecticides from different groups were evaluated: boric acid, an inorganic compound, benfuracarb, a carbamate, and halofenozide, a non-steroidal ecdysone agonist. Boric acid (8.20%, LD50) and benfuracarb (2%, LD50) were incorporated into the diet and orally administrated to newly emerged adults of both sexes, while halofenozide (0.33%, LD50) was applied topically. Hydrocarbons extracts was made on bidistilled pentane from control and treated series sampled 6 days following treatment. Extracts was analyzed by gas chromatography. Data showed that cuticular profiles of control and …
