Stratification of outcomes for mucinous appendiceal adenocarcinoma with peritoneal metastasis by histological grade.

Aim: To investigate the importance of a three-tiered histologic grade on outcomes for patients with mucinous appendiceal adenocarcinoma (MAA).

Methods: Two hundred and sixty-five patients with MAA undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were identified from a prospective database from 2004 through 2014. All pathology was reviewed by our gastrointestinal subspecialty pathologists and histological grade was classified as well-differentiated, moderately differentiated, and poorly differentiated.

Impact of High-risk Features and Effect of Neoadjuvant Chemotherapy in Urothelial Cancer Patients with Invasion into the Lamina Propria on Transurethral Resection in the Absence of Deep Muscle Invasion.

Background: High-risk non-muscle-invasive bladder cancer (NMIBC) that invades into the lamina propria is frequently understaged and is associated with a risk of lymph node metastasis and death.

Objective: To identify high-risk features (HRFs) for NMIBC that may identify patients with poorer prognosis who may benefit from neoadjuvant chemotherapy (NAC) prior to radical cystectomy (RC).

Design, Setting, And Participants: We performed a single-center retrospective review of patients who underwent RC for NMIBC with invasion into the lamina propria between 1995 and 2013.

Novel treatment for desmoplastic small round cell tumor: hyperthermic intraperitoneal perfusion.

Background: Less than 200 cases have been reported in the world literature since desmoplastic small round cell tumor (DSRCT) was first described in 1989. To date, chemotherapy, radiation therapy, and surgery have resulted in a poor survival of 30% to 55%. We used hyperthermic intraperitoneal chemotherapy (HIPEC) at the time of complete tumor resection as an adjunct to treatment of pediatric and adolescent patients with DSRCT.

Continuous hyperthermic peritoneal perfusion for desmoplastic small round cell tumor.

Desmoplastic small round cell tumor (DSRCT) is a rare disease of children, adolescents, and young adults that begins and spreads on the peritoneal surfaces. Desmoplastic small round cell tumor usually presents with diffuse abdominal metastatic disease similar in gross appearance to carcinomatosis. To date, very aggressive treatment programs have yielded dismal outcomes.

Chemoradiation for resectable gastric cancer.

The incidence of gastric cancer has been declining in recent years, however, the disease continues to be a worldwide public health problem. About two thirds of patients with gastric cancer undergo surgical resection with curative intent. R0 resection--complete local-regional tumour removal with negative resection margins--is the only curative modality.
