Sonidegib in the Treatment of Locally Advanced Basal Cell Carcinoma
2021
Sonidegib is an antagonist of the transmembrane protein Smoothened in the Hedgehog signaling pathway. It is indicated for the treatment of locally advanced basal cell carcinoma (BCC) that is not amenable to curative surgery or radiotherapy. Sonidegib's efficacy and safety were demonstrated in the phase 2 BOLT trial, where 61% (95% CI, 48-72%) of patients with locally advanced BCC treated with sonidegib 200 mg achieved an objective response to treatment with a mean time to response of 4 months. The median duration of response was 26.1 months and the median progression-free survival was 22.1 months. The most common adverse events were muscle spasms (54.4%), hair loss (49.4%), and loss of tast…
The Role of New Immunosuppressive Drugs in Nonmelanoma Skin Cancer in Renal Transplant Recipients
2014
Abstract Introduction Nonmelanoma skin cancer (NMSC) is the most common malignancy in patients who have received a solid organ transplant. Multiple factors are involved in the onset of posttransplant NMSC. Objectives To analyze the relationship between new immunosuppressive drugs and the onset of NMSC in renal transplant recipients. Method This was a combined retrospective and prospective observational study in which we studied 289 patients who received a kidney transplant between January 1996 and December 2010 at Hospital Universitario Doctor Peset in Valencia, Spain. Results Seventy-three patients (25.2%) developed 162 NMSCs over a median follow-up of 72 months. There were no statisticall…
Extranodal extension of nodal metastases is a poor prognostic moderator in non-small cell lung cancer: a meta-analysis
2018
Extranodal extension (ENE) of nodal metastasis is defined as the extension of metastatic cells through the nodal capsule into the perinodal tissue. This morphological parameter, recently proposed as an important prognostic factor in different types of malignancy, has not been included in the TNM staging system for non-small cell lung cancer (NSCLC). In this systematic review with meta-analysis, we weighted the prognostic role of ENE in patients with lymph node-positive NSCLC. Two independent authors searched SCOPUS and PubMed through 28 February 2017. Prospective and retrospective studies on NSCLC, comparing patients with presence of ENE (ENE+) ENE+) vs. only intranodal extension (ENE–) and…
Prognostic markers in low-grade papillary urothelial neoplasms of the urinary bladder
2005
Summary Papillary urothelial neoplasms (PUNs) of the urinary bladder comprise a heterogeneous spectrum of ‘continuous' lesions in which the assessment of an accurate histological grade and tumor stage is necessary for an adequate clinical management of patients. Recently, the 1998 World Health Organization/International Society of Urologic Pathologists (WHO/ISUP) Consensus Classification and the 1999 WHO classification proposed a new malignancy grading scheme based mainly on morphometric studies. In accordance with these grading systems, two major categories of PUNs were distinguished: low-grade and high-grade. Concerning the specific subgroup of low-grade tumors two other entities were def…
Immunohistochemical determination of estrogen and progesterone receptor content in human breast cancer
1993
Immunohistochemistry of Estrogen Receptor (ER) and Progesterone Receptor (PR) has been performed in 687 cases of human breast cancer. The staining results have been compared by (1) computer-assisted image analysis (QIC Score) and (2) subjective grading of the cryostat sections ("German" IRS). Tumors without or with only weak ER or PR content may be distinguished by both methods from tumors with a high receptor content. The QIC Score values belonging to the intermediate IRS grades are distributed over a wide range, but no negative cases were found in these categories. It is concluded from our results that subjective grading of the slides is a simple, rapid and useful method for the determina…
Prognostic comparison of the pathological classifications of gastric cancer: a population-based study
1998
Aims There is controversy over the value of the pathological classifications of gastric carcinomas in the prediction of patient survival. This study was designed to assess the prognostic value of four widely used pathological classifications, in addition to classical prognostic factors. Methods and results Records from the population-based registry of digestive tract tumours in the department of Cote d'Or (France) have been analysed. All available histopathological slides of gastric cancer resected between 1976 and 1985 were reviewed and classified according to World Health Organization (WHO), Lauren, Ming and Goseki pathological coding systems. A relative survival analysis was performed us…
A review of terms used to define cutaneous squamous cell carcinoma with a poor prognosis.
2020
Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer in humans and its incidence is both underestimated and on the rise. cSCC is referred to in the literature as high-risk cSCC, locally advanced cSCC, metastatic cSCC, advanced cSCC, and aggressive cSCC. These terms can give rise to confusion and are not always well defined. In this review, we aim to clarify the concepts underlying these terms with a view to standardizing the description of this tumor, something we believe is necessary in light of the new drugs that have been approved or are in development for cSCC.

Expression and prognostic value of the CD44 splicing variants v5 and v6 in gastric cancer
1997
In the present study, the expression and prognostic role of the CD44 splicing variants v5 and v6 were immunohistochemically investigated in 418 curatively resected gastric carcinomas. CD44v5 was expressed in 65·3 per cent (n=273) and CD44v6 in 77·0 per cent (n=322) of the tumours. Whereas the expression of CD44v5 was correlated with advanced pT categories, with lymph node involvement, and with the presence of blood and lymphatic vessel invasion, such a correlation could not be found for the variant v6. As shown by univariate analysis, patients with CD44v5-positive tumours had a significantly shorter overall survival than patients with CD44v5-negative tumours (P=0·049). In contrast, expressi…
