Lymphoparietal Index in Esophageal Cancer Is Stronger Than TNM Staging in Long-Term Survival Prognosis in a Latin-American Country

“…A previous experience of our group showed similar rate of leaks for AP and PP (p>0,05), but a worst post-operative morbidity concentrating all types CD III-V and lower OS3 for PP 5 . In the present study we found that AP is an independent prognostic factor for long term survival, probably because the lower rate of severe post-operative morbidity.…”

“…The definitions used were: a )TNM classification was standarized using the AJCC 7th edition 5 ; b) the lymphoparietal index (N+/T) calculates the quotient between the number of lymph nodes that are positive for adenocarcinoma metastasis and the T classification of the patient 12 , 13 , examples: 1/T1a=1/1=1, 6/T3 =6/3=2, 24/T4b=24/4=6) and the ratio results were divided into N+/T A : 0-0.5 and N+/T B : >0.5; c) surgical mortality was defined as occurring from the moment of surgery up to postoperative day 90; d) global survival was defined as of when the patient was discharged from the hospital, eliminating surgical mortality; e) long term survival was defined as survival greater than three years postoperative; f) zero time for determining prognostic association was the esophagectomy.…”

“…T he identification of some prognostic factors in oncologic disease has allowed to predict patient's evolution and guided therapeutic decision-making process to improve long-term survival 18,26 . However, in Chilean reality there are insufficient studies that analyze multiple prognostic factors of long-term survival in esophageal cancer [1][2][3][4][5][6][7][29][30][31][32] .…”
