Minimally invasive surgical staging for esophageal cancer. Luketich JD, Meehan M, Nguyen NT, Christie N, Weigel T, Yousem S, Keenan RJ, Schauer PR. BACKGROUND: The incidence of esophageal adenocarcinoma is increasing in the
United States, and the 5-year survival rate is dismal. Preliminary data suggest
that conventional imaging is inaccurate in staging esophageal cancer and could
limit accurate assessment of new treatments. The objective of this study was to
compare minimally invasive surgical staging (MIS) with conventional imaging for
staging esophageal cancer. METHODS: Patients with potentially resectable
esophageal cancer were eligible. Staging by conventional methods used computed
tomography (CT) scan of the chest and abdomen, and endoscopic ultrasound (EUS),
whereas MIS used laparoscopy and videothoracoscopy. Conventional staging results
were compared to those from MIS. RESULTS: In 53 patients, the following stages
were assigned by CT scan and EUS: carcinoma in situ (CIS; n = 1), I (n = 1), II
(n = 23), III (n = 20), IV (n = 8). In 17 patients (32.1%), MIS demonstrated
inaccuracies in the conventional imaging, reassigning a lower stage in 10
patients and a more advanced stage in 7 patients. CONCLUSIONS: In 32.1% of
patients with esophageal cancer, MIS changed the stage originally assigned by CT
scan and EUS. Therefore, MIS should be applied to evaluate the accuracy of new
noninvasive imaging methods and to assess new therapies for esophageal cancer. HOME | WHAT'S NEW | PROGRAMS & SERVICES | PHYSICIAN NEWSLETTER RELATED SITES | DOCTORS Search | Visit the Library | Visitors | E-mail Comments |
