Is an uncomplicated postoperative recovery following total pelvic exenteration a more important prognostic factor than achieving R0 in the first 2 years?

Aim: Total pelvic exenteration (TPE) can achieve an R0 resection in locally advanced and recurrent rectal cancer (LARC and RRC) and remains the only curative option. The resultant high morbidity creates prolonged complex recoveries, rendering patients unfit for adjuvant chemotherapy. This study aims to evaluate the impact of this on overall survival (OS) and disease-free survival (DFS) as it has not been studied previously.

Challenges in management of gastrointestinal cancers in pregnancies: A report of three cases.

Gastrointestinal cancer occurs in approximately 1 in 13,000 pregnancies, making up 4% of malignancies detected in pregnancy. It is a complex and challenging condition to diagnose and manage and is often only detected in its more advanced stages. This is partly due to symptoms of gastrointestinal cancer being incorrectly attributed to physiological symptoms of pregnancy, as well as concerns about the safety of diagnostic investigations in pregnancy, both of which may delay diagnosis and lead to disease progression.

High-throughput time-resolved FRET reveals Akt/PKB activation as a poor prognostic marker in breast cancer.

Dysregulation of the Akt/PKB pathway has been associated with poor prognosis in several human carcinomas. Current approaches to assess Akt activation rely on intensity-based methods, which are limited by the subjectivity of manual scoring and poor specificity. Here, we report the development of a novel assay using amplified, time-resolved Förster resonance energy transfer (FRET), which is highly specific and sensitive and can be adapted to any protein.

Functional implications of assigned, assumed and assembled PKC structures.

The empirical derivation of PKC (protein kinase C) domain structures and those modelled by homology or imputed from protein behaviour have been extraordinarily valuable both in the elucidation of PKC pathway mechanisms and in the general lessons that extrapolate to other signalling pathways. For PKC family members, there are many domain/subdomain structures and models, covering all of the known domains, variably present in this family of protein serine/threonine kinases (C1, C2, PB1, HR1, kinase domains). In addition to these structures, there are a limited number of complexes defined, including the structure of the PKCε V3-14-3-3 complex.
