Abstract
The prognostic significance of perineural invasion in patients with gastric cancer (GC) is controversial. This study aimed to determine the prognostic value of perineural invasion in patients with stage II/III GC undergoing radical surgery. A total of 1913 patients with stage II/III GC who underwent curative resection between 1994 and 2015 were recruited. Clinicopathological factors, tumor recurrence patterns, disease-free survival, and cancer-specific survival were compared in terms of perineural invasion. The prognostic factors of disease-free survival and cancer-specific survival were determined using univariate and multivariate analyses. Perineural invasion was found in 57.1% of the patients. Age of <65 years, female sex, large tumor size, upper tumor location, total gastrectomy, advanced tumor invasion depth and nodal involvement, greater metastatic to examined lymph node ratio, undifferentiated tumor, and presence of lymphatic or vascular invasion were significantly associated with perineural invasion. The patients with perineural invasion had higher locoregional/peritoneal recurrence rates than those without. Perineural invasion was independently associated with disease-free survival and cancer-specific survival. In conclusion, perineural invasion positivity is associated with aggressive tumor behaviors and higher locoregional/peritoneal recurrence rates in patients with stage II/III GC undergoing curative surgery. It is an independent unfavorable prognostic factor of disease recurrence and cancer-specific survival.

J Gastrointest Surg 2019; 23:895-903. [PMID: 30353490 DOI: 10.1007/s11605-018-4009-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2018] [Accepted: 10/09/2018] [Indexed: 02/05/2023]
Abstract
BACKGROUND The aim of the study is to present the clockwise, modularized lymphadenectomy model of laparoscopic gastrectomy for gastric cancer patients, which is based on our clinical practice experience in laparoscopic gastric cancer surgery. METHODS From Jan 2015 to July 2017, 116 patients who underwent laparoscopic gastrectomy were retrospectively collected and analyzed. According to the different resection models, patients were divided into two groups: traditional laparoscopic lymphadenectomy group (63 patients) and clockwise, modularized lymphadenectomy group (53 patients). Operation-related parameters were compared between the two groups. RESULTS The clockwise, modularized lymphadenectomy group had less dissection time (119.8 ± 19.1 min vs. 135.3 ± 23.8 min, p < 0.001) and less intraoperative blood loss (81.7 ± 42.9 ml vs. 91.4 ± 28.7 ml, p = 0.016) compared with the traditional laparoscopic lymphadenectomy group. Meanwhile, the clockwise, modularized lymphadenectomy group had more numbers of examined lymph nodes (40.5 ± 14.3 vs. 33.9 ± 11.0, p = 0.007) than the traditional laparoscopic lymphadenectomy group. Besides, there was no statistically significant difference in the postoperative complication rates between the two groups. The clockwise, modularized lymphadenectomy group had shorter postoperative hospital stay than the traditional laparoscopic lymphadenectomy group (8.7 ± 3.2 days vs. 10.4 ± 3.9 days, respectively, p < 0.001). CONCLUSIONS Through the adoption of the fixed sequence of lymphadenectomy, requirements and standard of lymphadenectomy of each lymph node station, and specific surgical skills for intraoperative exposure by the clockwise and modularized lymphadenectomy model, we can optimize and facilitate the laparoscopic gastric cancer surgery.

World J Surg Oncol 2018; 16:116. [PMID: 29925390 PMCID: PMC6011414 DOI: 10.1186/s12957-018-1412-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2017] [Accepted: 06/07/2018] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND To study metastasis to the infra-pyloric (no. 6) lymph nodes and their subgroups and the related risk factors of gastric cancer patients. METHODS Gastric cancer patients who underwent gastrectomy with complete postoperative pathological information on the no. 6 lymph node station and its subgroups from January 1, 2008, to December 31, 2011, were included. The clinicopathological characteristics and survival outcomes were analyzed. RESULTS A total of 121 patients were included; they had 6.1 ± 7.7 positive lymph nodes, and 35.1 ± 14.2 lymph nodes were examined. The overall lymph node positivity rate was 67.8% (82/121) with a positivity rate of 28.1% (34/121) for the no. 6 lymph nodes. The metastasis rate was 6.6% for the no. 6a nodes, 6.6% for the no. 6b nodes, and 21.5% for the no. 6c nodes. Also, no. 8a (OR = 1.329, p = 0.017) and no. 9 (OR = 1.250, p = 0.022) nodal positivity and lower third tumor location (OR = 1.278, p = 0.001) were independent risk factors for no. 6 lymph nodal metastasis. There was a significant survival difference between patients with positive and negative no. 6 lymph nodes and patients with metastasis to other lymph node stations (p < 0.001). CONCLUSIONS Patients with no. 6 lymph node metastasis have poor survival outcomes. Complete infra-pyloric lymphadenectomy is necessary and crucial for gastric cancer patients.
