ABH-antigenicity of transitional cell carcinoma of the urinary bladder in patients subjected to topical chemoprophylaxis

1983

Topical chemoprophylaxis with adriamycin was administered to 49 patients with UICC-stages pTA and PT1 (pathological stage 0 and A) of transitional cell carcinoma of the urinary bladder. Tumor specimens obtained prior to initiation of the instillation protocol were evaluated with regard to ABH-antigenicity. ABH-antigens were present in tumors of 19 patients and none of these developed muscle-infiltrating recurrences during or after intravesical chemoprophylaxis. The primary lesions of 30 patients were deleted of antigens; only 5 (16%) developed a progressive recurrence. Compared to a historical control group this is thought to be a true reduction of invasive tumor recurrences in ABH-negative…

Safety and Pharmacokinetics/Pharmacodynamics of the First-in-Class Dual Action HER3/EGFR Antibody MEHD7945A in Locally Advanced or Metastatic Epithel…

2015

Abstract Purpose: The novel dual-action humanized IgG1 antibody MEHD7945A targeting HER3 and EGFR inhibits ligand-dependent HER dimer signaling. This phase I study evaluated the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of MEHD7945A. Experimental Design: Patients with locally advanced or metastatic epithelial tumors received escalating doses of MEHD7945A (1–30 mg/kg) every 2 weeks (q2w) until disease progression or intolerable toxicity. An expansion cohort was enrolled at the recommended phase II dose (14 mg/kg, q2w). Plasma samples, tumor biopsies, FDG-PET were obtained for assessment of pharmacokinetics, and pharmacodynamic modulation downstream of EGFR and HER3. …

Vinblastine and interferon-alpha-2a regimen in the treatment of metastatic renal cell carcinoma.

1990

Thirteen patients with histologically proven advanced and/or metastatic renal cell carcinoma (RCC) were treated with vinblastine (Velbe, Eli Lilly, Sesto Fiorentino, Italy) and interferon-alpha-2a (Roferon-A, Roche, Milan). Eleven out of 13 patients were evaluable. Eighteen percent of patients had partial response, 46 % stable disease (SD), and 36 % progressive disease (PD). The mean survival of responders was 228+ days, whereas the patients showing SD and PD had a mean survival of 154+ and 107+ days respectively. Toxicity, including influenza-like syndrome, fever, neurological and gastrointestinal side effects, was generally mild. However, medication with paracetamol was required in 82 % …

Biopsy vs. brushing: comparison of two sampling methods for the detection of HPV-DNA in squamous cell carcinoma of the oral cavity

2012

Background: HR HPV infection was proposed as aetiological factor of oral squamous cell carcinomas (OSCC). HPV frequency in OSCC is highly variable, due to the discrepancy in oral sampling procedures, HPV testing methods and inclusion criteria regarding tumour site (strictly oral cavity vs. nearby structures). Our aim was to compare HPV DNA frequency and type-specific distribution in paired cytological and histological samples of SCC strictly located in oral cavity. The correlation between HPV detection rate by each method of sampling and demographical, behavioural and clinical-pathological variables was also examined. Patients and methods: HPV DNA was detected in brushed cells and formalin-…

Stereotactic Radiotherapy for the Treatment of Patients With Oligo-progressive Metastatic Renal Cell Carcinoma Receiving Vascular Endothelial Growth …

2020

Aim This retrospective observational study evaluated the role of hypo-fractionated stereotactic radiotherapy (SRT) in patients with oligo-progressive metastatic renal cell carcinoma (mRCC) treated with first-line oral tyrosine kinase inhibitors (TKI). Data on local control, delay of further progression, and safety are reported. Patients and methods Between January 2010 and December 2016, 28 patients with mRCC who showed oligo-progressive disease while receiving first-line pazopanib were treated with hypofractionated SRT to progressive metastatic sites to delay the change of systemic therapy. First and second progression-free survival (PFS-1 and PFS-2) were recorded, as well as objective res…

Bone metastases in patients with metastatic renal cell carcinoma: are they always associated with poor prognosis?

2015

Purpose: Aim of this study was to investigate for the presence of existing prognostic factors in patients with bone metastases (BMs) from RCC since bone represents an unfavorable site of metastasis for renal cell carcinoma (mRCC). Materials and methods: Data of patients with BMs from RCC were retrospectively collected. Age, sex, ECOG-Performance Status (PS), MSKCC group, tumor histology, presence of concomitant metastases to other sites, time from nephrectomy to bone metastases (TTBM, classified into three groups: <1 year, between 1 and 5 years and >5 years) and time from BMs to skeletal-related event (SRE) were included in the Cox analysis to investigate their prognostic relevance. R…

Expression of sexual hormones receptors in oral squamous cell carcinoma.

2011

Sexual hormones play an important role in expression of genes involved in a wide variety of biological and neoplastic processes. The information on Estrogen Receptors (ER) expression in non-target tissues is very few and, in particular, the studies in head and neck tumors are still controversial. Recent studies analyzed the role of Tamoxifen (TAM) on Oral Squamous Cell Carcinoma (OSCC) lines in relation to the presence/absence of ER. The purpose of the present study was to evaluate the expression of sexual hormones receptors mRNAs, in particular Estrogen Receptor alpha (ERα) and Androgen Receptor (AR) mRNA in OSCC tissues. The study group comprised 20 samples of OSCC, harvested from 20 oth…

Effect of c-Met expression on survival in head and neck squamous cell carcinoma

2005

The proto-oncogene c-Met has been suggested to be associated with progression of squamous cell carcinoma of the head and neck. The aims of the present study were to assess the prevalence of c-Met expression in oral squamous cell carcinoma (OSCC) and to verify whether c-Met can be considered a marker of prognosis in these patients. In a retrospective study, a cohort of 84 OSCC patients was investigated for c-Met expression and its cellular localization by immunohistochemistry. After grouping for c-Met expression, OSCC patients were statistically analyzed for the variables age, gender, histological grading, tumor node metastasis, staging and overall survival rate. Univariate and multivariate …
