Predictive factors of lymphatic metastasis and evaluation of the Japanese treatment guidelines for endoscopic resection of early gastric cancer in a high-volume center in Perú.

Purpose: This study aimed to identify the predictive factors of lymph node metastasis (LNM) in patients with early gastric cancer (EGC) and to evaluate the applicability of the Japanese treatment guidelines for endoscopic resection in the western population.

Methods: Five hundred-one patients with pathological diagnoses of EGC were included. Univariate and multivariate analyses were conducted to identify the predictive factors of LNM.

Open versus minimally invasive sphincter-sparing surgery for rectal cancer: a single-center retrospective cohort study in Peru.

Objective: The study aimed to describe and compare minimally invasive surgery (MIS) and open surgery for rectal cancer in Peru.

Material And Methods: A retrospective single-center analysis was performed for all patients who underwent sphinctersparing surgery for non-metastatic rectal cancer at Instituto Nacional de Enfermedades Neoplásicas in Peru between January 2016 and December 2020. Clinical, perioperative, pathological, and survival outcomes were compared between both groups.

Clinicopathological factors associated with recurrence in patients undergoing resection of pancreatic solid pseudopapillary neoplasm.

Purpose: Solid pseudopapillary neoplasm (SPN) is an uncommon pathology with a low-grade malignancy. Surgery is the milestone treatment. Nevertheless, despite appropriate management, some patients present recurrence.

Clinicopathological factors associated with the presence of tumor deposits in resected gastric cancer patients.

Purpose: The role of tumor deposits (TDs) in the staging of gastric cancer is currently debatable. TDs are defined as tumoral nodules in perigastric adipose tissue with no evidence of lymphatic, vascular, or neural structures. Clinicopathological factors related to the presence of TDs are not well defined.

TransAnal Total Mesorectal Excision (TaTME) in Peru: Case series.

Introduction: Describe and demonstrate the feasibility and safety of TaTME in short term outcomes in the Instituto Nacional de Enfermedades Neoplásicas (INEN) in Peru.

Materials And Methods: Case series with retrospective and prospective data collection of patients with middle and inferior rectal cancer who underwent TaTME between January 2015 and March 2020. Patients and tumor characteristics, operative details, postoperative complications and pathological results were analyzed.

[Prognostic value of lymph node ratio (LNR) in patients who underwent radical gastrectomy].

Unlabelled: The study objective was to evaluate the prognostic value of lymph node ratio (LNR) in patients with gastric cancer who underwent radical gastrectomy D2.

Materials And Methods: We reviewed retrospectively 498 medical records of patients with gastric cancer who were attended at the National Institute of Neoplastic Diseases (INEN) between 2008 and 2011and met the inclusion and exclusion criteria. They were distributed into 4 groups according to their LNR, LNR0: 0, LNR1: 0-0.

[Does contribute early enteral nutrition to decrease the complications of radical gastrectomy for gastric cancer?].

Objective: To evaluate whether the administration of early enteral nutrition in postoperative gastrectomized patients due gastric cancer helps to reduce the frequency of postoperative complications.

Materials And Methods: A case-control study with 120 patients, 60 with postoperative complications (cases) and 60 patients without post operative complications (controls) matched for age and sex.

Results: The uni-variable analysis found that albumin (p=0.
