Identification of Blood-Based Biomarkers for the Prediction of the Response to Neoadjuvant Chemoradiation in Rectal Cancer.

Cancers (Basel) 2021 Jul 20;13(14). Epub 2021 Jul 20.

Department of Translational Molecular Pathology, The University of Texas MD Anderson Cancer Center, Houston, TX 77030, USA.

The current standard of care for patients with locally advanced rectal cancer (LARC) is neoadjuvant chemoradiation (nCRT) followed by total mesorectal excision surgery. However, the response to nCRT varies among patients and only about 20% of LARC patients achieve a pathologic complete response (pCR) at the time of surgery. Therefore, there is an unmet need for biomarkers that could predict the response to nCRT at an early time point, allowing for the selection of LARC patients who would or would not benefit from nCRT.

Narrative review of penile distal urethroplasties and suggestions for optimizing outcomes.

Transl Androl Urol 2021 Jun;10(6):2609-2616

University of Lisbon, Lisbon, Portugal.

Distal urethral strictures can be a challenging entity for urologists. Endoscopic maneuvers such as optical internal urethrotomies or dilations are even less successful than in other urethral locations and the repeated trauma will increase the scarring which advocates for a urethroplasty as primary option for patient management. Success rates of distal urethroplasties have been lower than those for other urethral strictures due to the anatomy of the distal urethra with a very thin corpus spongiosum associated with decreased mucosal blood supply.

[Position paper on endoscopic reporting in IBD].

Z Gastroenterol 2021 Jul 20. Epub 2021 Jul 20.

Medizinische Klinik 1, Universitätsklinikum Erlangen, Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany.

The complete and reliable documentation of endoscopic findings make up the crucial foundation for the treatment of patients with inflammatory bowel diseases such as Crohn´s disease and ulcerative colitis. These findings are, on the one hand, a prerequisite for therapeutic decisions and, on the other hand, important as a tool for assessing the response to ongoing treatments. Endoscopic reports should, therefore, be recorded according to standardized criteria to ensure that the findings of different endoscopists can be adequately compared and that changes in the course of the disease can be traced back.
