Advances in Diagnostic, Staging, and Restaging Evaluation of Esophageal and Gastric Cancer.

The initial endoscopic and staging evaluation of esophagogastric cancers must be accurate and comprehensive in order to select the optimal therapeutic plan for the patient. Esophageal and gastric cancers (and treatment paradigms) are delineated by their proximity to the cardia (within 2 cm). The most frequent and important symptom that informs the initial staging evaluation is dysphagia, which is associated with at least cT3 or locally advanced disease. Endoscopic ultrasound is often needed if earlier stage disease is suspected, preferably in combination with endoscopic mucosal or submucosal resection or fine-needle aspiration of suspicious lymph nodes to enhance staging accuracy.

Treatment of esophageal adenocarcinoma in patients with a history of bariatric surgery.

BACKGROUND: The relationship among obesity, bariatric surgery, and esophageal adenocarcinoma (EAC) is complex, given that some bariatric procedures are thought to be associated with increased incidence of reflux and Barrett's esophagus. Previous bariatric surgery may complicate the use of the stomach as a conduit for esophagectomy. In this study, we presented our experience with patients who developed EAC after bariatric surgery and described the challenges encountered and the techniques used. METHODS: We conducted a retrospective review of our institutional database to identify all patients at our institution who were treated for EAC after previously undergoing bariatric surgery. RESULTS: In total, 19 patients underwent resection with curative intent for EAC after bariatric surgery, including 10 patients who underwent sleeve gastrectomy. The median age at diagnosis of EAC was 63 years; patients who underwent sleeve gastrectomy were younger (median age, 56 years). The median time from bariatric surgery to EAC was 7 years. Most patients had a body mass index (BMI) score of >30 kg/m2 at the time of diagnosis of EAC; approximately 40% had class III obesity (BMI score > 40 kg/m2). Six patients (32%) had known Barrett's esophagus before undergoing a reflux-increasing bariatric procedure. Sleeve gastrectomy patients underwent esophagectomy with gastric conduit, colonic interposition, or esophagojejunostomy. Only 1 patient had an anastomotic leak (after esophagojejunostomy). CONCLUSION: Endoscopy should be required both before (for treatment selection) and after all bariatric surgical procedures. Resection of EAC after bariatric surgery requires a highly individualized approach but is safe and feasible.

Outcomes of Patients Undergoing Segmentectomy for Occult Node-Positive Clinical Stage IA Lung Cancer.

BACKGROUND: Results of recent clinical trials suggest that segmentectomy may be an acceptable alternative to lobectomy for selected patients with early-stage non-small cell lung cancer (NSCLC). Increased use of segmentectomy may result in a concomitant increase in occult node-positive (N+) disease on surgical pathology examination. The optimal management for such patients remains unknown. METHODS: Clinicopathologic data were abstracted from a prospective institutional database to identify patients with pathologic N+ disease after segmentectomy for cT1 N0 M0 NSCLC. Propensity score matching identified a comparable lobectomy cohort for assessment of cumulative incidence of recurrence and overall survival (OS). RESULTS: Of 759 included patients, 27 (4%) had nodal upstaging on the final pathology report. Of these 27 patients, 4 (15%) had skip metastasis to N2 stations, and 20 (74%) received adjuvant therapy; no completion lobectomies were performed. Ten patients (37%) had disease recurrence: 3 isolated locoregional (11%) and 7 distant (26%). The median time to recurrence among patients with recurrence was 1.8 years; OS after recurrence was 3.4 years. After 5:1 matching with 109 patients who underwent lobectomy, all variables were balanced between the groups, except pathologic N2 stage and open surgical approach. The 5-year cumulative incidence of recurrence was not significantly different between segmentectomy and lobectomy (42% vs 52%, respectively; Gray's P = .1). The 5-year OS (63% and 50%) and rate of locoregional recurrence (12% vs 13%) were not statistically different between the groups. CONCLUSIONS: Patients with occult N+ disease after segmentectomy for cT1 N0 M0 NSCLC had limited isolated locoregional recurrences and outcomes similar to those in patients who underwent lobectomy. Lobectomy may not provide an advantage in these patients.
