This case report describes a 63-year-old female with a locally advanced esophageal carcinoma cuniculatum treated with definitive chemoradiation who had a rapid and early response. This case is illustrative of an aggressive behavior with rapid response and rapid recurrence. The cases of esophageal carcinoma cuniculatum as well as the closely related clinical entity of verrucous carcinoma are reviewed suggesting good clinical outcomes after definitive therapy with chemoradiation and/or surgery.

 The impact of the advent of an institutional endoscopic eradication therapy (EET) program on surgical practice for Barrett's esophagus (BE)-associated high grade dysplasia (HGD) or suspected T1a esophageal adenocarcinoma (EAC) is unknown. The aims of this study are to evaluate the different endoscopic modalities used during development of our EET program and factors associated with the use of EET or surgery for these patients after its development.  Patients who underwent primary endoscopic or surgical treatment for BE-HGD or early EAC at our hospital between January 1992 and December 2014 were retrospectively identified.

Objectives: Anastomotic complications represent a significant source of morbidity and occasionally mortality after esophagectomy. Since 2009, we have used a novel "side-to-side: staple line-on-staple line" (STS) technique for intrathoracic esophagogastric anastomoses, designed to create a wide-diameter esophagogastric anastomosis while preserving stomach conduit blood supply. In this study, we describe the technique and review outcomes of our institution's initial 6-year experience.

Background: Since 2001 we have utilized a novel surgical approach for Pancoast tumors in which lobectomy and mediastinal lymph node dissection are performed directly though the chest wall defect. The defect is then patched at the completion of the procedure ("cut-in patch-out") thereby avoiding a separate thoracotomy with rib spreading. We undertook a study to compare outcomes of this novel "cut-in patch-out" technique with traditional thoracotomy for patients with Pancoast tumors.

Background: When the stomach is not available, long-segment esophageal reconstruction remains a surgical challenge. Since 2005, we have used a "supercharged" isoperistaltic colon interposition conduit for long-segment esophageal reconstruction that reestablishes a dual blood supply.

Methods: An institutional database search of 449 patients who underwent esophagectomy from 2005 to 2012 identified 11 consecutive patients who underwent long-segment esophageal reconstruction using an isoperistaltic supercharged right (n=9) or left (n=2) colon conduit.

Objective: Criteria for the growing teratoma syndrome in patients with primary mediastinal nonseminomatous germ cell tumors have not been well established according to current practice.

Methods: An institutional database identified 188 patients who underwent postchemotherapy surgery for primary mediastinal nonseminomatous germ cell tumors from 1981 to 2009. We reviewed the subset of patients who underwent urgent surgery for tumor growth resulting in cardiopulmonary deterioration secondary to mediastinal compression precluding safe completion of 4 cisplatin-based chemotherapy cycles with rapidly declining serum tumor markers.

Background: Since the advent of cisplatin-based chemotherapy, nonseminomatous germ cell tumors (NSGCT) have been considered one of the most curable solid neoplasms and a model for multimodality cancer therapy. We undertook an institutional review of testicular NSGCT patients who underwent operations to remove lung or mediastinal metastases after chemotherapy in the cisplatin era to determine outcomes.

Methods: From 1980 to 2006, 431 patients underwent 640 postchemotherapy surgical procedures to remove lung (n = 159, 36.

Purpose: This study was performed to discover prognostic genomic markers associated with postoperative outcome of stage I to III non-small cell lung cancer (NSCLC) that are reproducible between geographically distant and demographically distinct patient populations.

Experimental Design: American patients (n = 27) were stratified on the basis of recurrence and microarray profiling of their tumors was performed to derive a training set of 44 genes. A larger Korean patient validation cohort (n = 138) was also stratified by recurrence and screened for these genes.
