Pelvic Exenteration in Advanced, Recurrent or Synchronous Cancers-Last Resort or Therapeutic Option?

First described some 80 years ago, pelvic exenteration remain controversial interventions with variable results and ever-changing indications. The previous studies are not homogenous and have different inclusion criteria (different populations and different disease characteristics) and methodologies (including evaluation of results), making it extremely difficult to properly assess the role of pelvic exenteration in cancer treatment. This study aims to describe the indications of pelvic exenterations, the main prognostic factors of oncologic results, and the possible complications of the intervention.

Scars Run Deep: Problematic Morphology and Immunoprofile of Scars in Renal Oncocytomas.

In some instances, the central scar of renal oncocytoma can demonstrate entrapped cells with unusual morphology and aberrant immunoprofile creating potential diagnostic confusion. Herein, 100 renal oncocytomas containing scars with embedded epithelial cells were identified from 6 institutions, including nephrectomies (64% partial, 36% radical) of similar laterality (left = 51%) and sex distribution (male = 56%), with patient ages ranging from 38 to 86 years (mean = 64.3years) and tumor sizes ranging from 2 to 16 cm (mean = 5.

[Serrated polyps and their association with synchronous advanced colorectal neoplasia].

Introduction: Large serrated polyps (SP), proximal SP, SP with dysplasia and the presence of multiple sessile serrated adenomas/polyps (SSA/P), which we refer to as SP with increased risk of metachronous lesions (SPIRML), have been associated with an increased risk of advanced colon lesions on follow-up. It is unclear, however, whether SPIRML are also associated with an increased risk of synchronous advanced colorectal neoplasia (ACN).

Aim: The aim of this study was to estimate the prevalence of SPIRML and to evaluate the association between SPIRML and synchronous ACN.
