Utility of D2-40, Cytokeratin 5/6, and High-Molecular-weight Cytokeratin (Clone 34βE12) in Distinguishing Intraductal Spread of Urothelial Carcinoma From Prostatic Stromal Invasion.

Am J Surg Pathol 2021 Sep 23. Epub 2021 Sep 23.

Departments of Pathology and Laboratory Medicine Urology Sylvester Comprehensive Cancer Center, University of Miami Miller School of Medicine, Miami, FL.

Intraductal spread of urothelial carcinoma (UC) is not an uncommon finding in bladder cancer that requires appropriate clinical management. The presence of prostatic stromal invasion in non-muscle-invasive bladder cancer upstages the disease, necessitating cisplatin-based neoadjuvant chemotherapy and subsequent cystroprostatectomy. However, the identification of prostatic stromal invasion can be challenging, especially in biopsy and transurethral resection specimens. Read More

Hyperprogression after Immunotherapy: Nivolumab. Analysis of Imaging Findings Associated with Hyperprogression and Tumor Growth Kinetics.

Indian J Radiol Imaging 2021 Apr 27;31(2):345-349. Epub 2021 Jul 27.

Department of Radiology, Rajiv Gandhi Cancer Institute and Research Centre, Delhi, India.

The increased use of new checkpoint inhibitors in cancer therapy has led to the discovery of new unconventional responses, like pseudoprogression and hyperprogression disease (HPD). The study documents imaging findings of HPD and analyzes the growth kinetics in advanced metastatic cancers patients treated with immunotherapy. We retrospectively reviewed patients treated with anti-PD-1 (anti-progressive disease-1) antibody therapy (nivolumab) between January 2017 and December 2017 at our institute. Read More

Nadia Peparini

Surg Oncol 2021 Sep 2;38:101639. Epub 2021 Aug 2.

Azienda Sanitaria Locale Roma 6, Distretto 3, via Mario Calo' 5, 00043, Ciampino (Rome), Italy. Electronic address:

The mesopancreas does not have well-defined boundaries but is continuous and connected through its components with the paraaortic area. The mesopancreatic resection margin has been indicated as the primary site for R1 resection after PD in pancreatic head cancer and total mesopancreas excision has been proposed to achieve adequate retropancreatic margin clearance and to minimize the likelihood of R1 resection. However, the anatomy of the mesopancreas requires extended dissection of the paraaortic area to maximize posterior clearance. Read More

Augmented reality head-mounted display-based incision planning in cranial neurosurgery: a prospective pilot study.

Neurosurg Focus 2021 08;51(2):E3

1Department of Neurological Surgery, University of Miami Miller School of Medicine; and.

Objective: Monitor and wand-based neuronavigation stations (MWBNSs) for frameless intraoperative neuronavigation are routinely used in cranial neurosurgery. However, they are temporally and spatially cumbersome; the OR must be arranged around the MWBNS, at least one hand must be used to manipulate the MWBNS wand (interrupting a bimanual surgical technique), and the surgical workflow is interrupted as the surgeon stops to "check the navigation" on a remote monitor. Thus, there is need for continuous, real-time, hands-free, neuronavigation solutions. Read More

Service de chirurgie digestive et oncologique, hôpital Bicêtre, AP-HP, Le Kremlin Bicêtre, France; Université Paris Saclay, UMR-S 1193, 94800 Villejuif, France.

The standard of care for patients with locally advanced rectal cancer has recently changed and is now based on the concept of total neoadjuvant therapy with the association of radiotherapy and systemic chemotherapy before radical surgery. The addition of noeadjuvant systemic chemotherapy before or after radiotherapy during preoperative course significantly decreased the risk of distant metastases and prolonged disease-free survival after surgery. The risk of recurrence varies among patients and the standard management associating chemotherapy, radiotherapy and surgery may expose many patients to overtreatment and can negatively affect quality of life.
