Cervical squamous cell carcinoma of the esophagus-a unique series of limited resection and free jejunal graft interposition after neoadjuvant RCTx in 94 patients

Abstract

4572 Background: The treatment of cervical squamous cell carcinoma (SCC) is discussed controversial. A limited resection of the cervical esophagus and reconstruction with a free jejenunal graft interposition using a microsurgical technique has been evaluated in our department. Methods: From 1986–2006 94 patients with the initial staging uT2–4, N any cM0 (75 male, 19 female; age 56+9.6, range: 19–74 years) with cervical SCC of the esophagus were treated with limited esophageal resection and reconstructed with a free jejunal autograft in combination after neoadjuvant RCTx within phase II studies. The median follow up is 23 months (0.1–120). Results: Laryngectomie had to be performed in 13 patients (14%). Recurrent nerve palsy on one side was found in 15/77 (19.5%) and on both sides in 13/77 (17%). Complications occurred in 70 (75%) of the patients, 47% of the patients had more than one complication. Reoperations were necessary in 29 patients (31%). The 30-day mortality was 2/94 (2.1%). Median survival is 29.9 months (1-, 3 and 5-year survival rates: 81%, 43%, 41%). 27/94 (29%) patients showed complete tumor regression (ypT0) after RCTx. Prognostic factors are complete tumor regression (p=0.007), ypT-(p=0.006), the R-category (p=0.018), but not the ypN-category (p=0.06). Neither the occurrence of complications (p=0.57) nor reoperation (p=.89) are associated with survival. The complete resection rate was 76 % (71/94). Median survival is 34.3 months, median recurrence free survival is 21.4 months for the R0 resected patients. 30/71 (42%) had a recurrence (locoregional in 27% (19/71), distant metastases in 10% (7/71) and a combination of both in 6% (4/71). Conclusions: Limited resection of the esophagus and reconstruction by a free jejunal graft after neoadjuvant RCTx is highly sophisticated and complex. Despite a high complication and reoperation rate the results are excellent with a low mortality and a good prognosis. This approach seems to be appropriate for cervical SCC in oncological centers with an infrastructure providing interdisciplinary management. Comparable data for cervical SCC of the esophagus without the inclusion of hypopharyx carcinoma do not exist in literature so far. No significant financial relationships to disclose.
