Synchronous resection of esophageal cancer and other organ malignancies: A systematic review.
(Systematic Review;Journal Article)
Neoplasms arising in the esophagus may coexist with other solid organ or gastrointestinal tract neoplasms in 6% to 15% of patients. Resection of both tumors synchronously or in a staged procedure provides the best chances for long-term survival. Synchronous resection of both esophageal and second primary malignancy may be feasible in a subset of patients; however, literature on this topic remains rather scarce.
To analyze the operative techniques employed in esophageal resections combined with gastric, pancreatic, lung, colorectal, kidney and liver resections and define postoperative outcomes in each case.
We conducted a systematic review according to PRISMA guidelines. We searched the Medline database for cases of patients with esophageal tumors coexisting with a second primary tumor located in another organ that underwent synchronous resection of both neoplasms. All English language articles deemed eligible for inclusion were accessed in full text. Exclusion criteria included: (1) Hematological malignancies; (2) Head/neck/pharyngeal neoplasms; (3) Second primary neoplasms in the esophagus or the gastroesophageal junction; (4) Second primary neoplasms not surgically excised; and (5) Preclinical studies. Data regarding the operative strategy employed, perioperative outcomes and long-term outcomes were extracted and analyzed using descriptive statistics.
The systematic literature search yielded 23 eligible studies incorporating a total of 117 patients. Of these patients, 71% had a second primary neoplasm in the stomach. Those who underwent total gastrectomy had a reconstruction using either a colonic (n
= 23) or a jejunal (n
= 3) conduit while for those who underwent gastric preserving resections (i.e
., non-anatomic/wedge/distal gastrectomies) a conventional gastric pull-up was employed. Likewise, in cases of patients who underwent esophagectomy combined with pancreaticoduodenectomy (15% of the cohort), the decision to preserve part of the stomach or not dictated the reconstruction method (whether by a gastric pull-up or a colonic/jejunal limb). For the remaining patients with coexisting lung/colorectal/kidney/liver neoplasms (14% of the entire patient population) the types of resections and operative techniques employed were identical to those used when treating each malignancy separately.
Despite the poor quality of available evidence and the great interstudy heterogeneity, combined procedures may be feasible with acceptable safety and satisfactory oncologic outcomes on individual basis.
