Commitment of Scaffold Proteins in the Onco-Biology of Human Colorectal Cancer and Liver Metastases after Oxaliplatin-Based Chemotherapy.

ABSTRACT: Scaffold proteins play pivotal roles in the regulation of signaling pathways, integrating external and internal stimuli to various cellular outputs. We report the pattern of cellular and subcellular expression of scaffoldins angiomotin-like 2 (AmotL2), FK506 binding protein 5 (FKBP51) and IQ motif containing GTPase-activating protein 1 (IQGAP1) in colorectal cancer (CRC) and metastases in liver resected after oxaliplatin-based chemotherapy (CT). Positive immunostaining for the three scaffoldins was found in most cells in healthy colon, tumor, healthy liver and metastasized liver. The patterns of expression of AmotL2, FKBP51 and IQGAP1 show the greatest variability in immune system cells and neurons and glia cells and the least in blood vessel cells. The simultaneous subcellular localization in tumor cells and other cell types within the tumor suggest an involvement of these three scaffoldins in cancer biology, including a role in Epithelial Mesenchymal Transition. The display in differential localization and quantitative expression of AmotL2, FKBP51, and IQGAP1 could be used as biomarkers for more accurate tumor staging and as potential targets for anti-cancer therapeutics by blocking or slowing down their interconnecting functions. Tough further research needs to be done in order to improve these assessments.

Project description:Pressurized intraperitoneal aerosol chemotherapy with oxaliplatin (PIPAC-OX) is increasingly used as a palliative treatment option for patients with colorectal peritoneal metastases (CPM). The present study aimed to systematically review all clinical studies reporting safety and efficacy outcomes of PIPAC-OX in patients with CPM. PubMed, EMBASE, The Cochrane Library, and CINAHL were systematically searched to identify all clinical studies that included at least one patient with CPM treated with PIPAC-OX and reported one of the following outcomes: adverse events, tumor response, quality of life, secondary cytoreductive surgery, progression-free survival, overall survival, and environmental safety of PIPAC-OX. Results were narratively described. Of 28 included studies, only 14 non-comparative studies separately reported at least one outcome of PIPAC-OX for CPM, of which only two studies specifically focused on this group. These 14 studies reported adverse events (5 studies), tumor response (5 studies), secondary cytoreductive surgery (4 studies), progression-free survival (1 study), overall survival (5 studies), and environmental safety (2 studies). Except for 5 studies (describing 26 patients), none of the included studies stratified their results for PIPAC-OX monotherapy and PIPAC-OX with concomitant systemic therapy, and none of the studies reporting survival outcomes stratified results for line of palliative treatment, complicating interpretation. No PIPAC-OX related deaths were reported. No occupational platinum was detected during PIPAC-OX. The available evidence regarding PIPAC-OX for CPM is limited and difficult to interpret. Despite these limitations, PIPAC-OX appears safe in patients with CPM and safe for operating personnel. To increase insight in the role of PIPAC-OX in this setting, investigators of ongoing and future studies are encouraged to report separate outcomes of PIPAC-OX for CPM, to stratify their results for PIPAC-OX monotherapy and PIPAC-OX with concomitant systemic therapy, and to stratify survival results for line of palliative treatment.
