ABSTRACT

Objective:

To explore the clinico-pathological characteristics and risk factors affecting prognosis in elderly patients with gastric cancer.

Methods:

A retrospective study was used to retrospectively analyze 2386 patients with gastric cancer undergoing radical surgery in Surgery Department of the Fourth Hospital of Hebei Medical University from 1 January 2012 to 1 January 2015.Patients aged 70 years and older were screened so as to analyze clinical characteristics and influencing factors for the prognosis.

Results:

A total of 2386 patients with gastric cancer were divided into the elderly group aged 70 years and older(342 of 2386 cases, 14.3%). There were statistically significant differences between the two groups in gender, number of concomitant diseases, NRS2002 score, PG-SGA score, tumor location, tumor diameter, histological type, Borrmann classification, tumor invasion depth staging(pT), lymph node metastasis staging(pN), the anatomic extent of tumor staging(TNM, pTNM), and Lauren classifications( P<0.05). The 981 of 2386 cases(41.4%)had postoperative complications, accompanied by 413 cases(17.3%)of surgery-related complications and 568 cases(24.0%)of non-surgery-related complications.A multivariate logistic analysis showed that the number of preoperative co-existing diseases ≥ 2 was an independent influencing factor for postoperative complications in elderly gastric cancer patients( HR=4.478, 95% CI 1.121-7.918, P=0.006). The 5-year OS and DSS was 21.10% and 62.73% in the ≥70 years gastric cancer group, and was 54.1% and 70.0% in the <70 years gastric cancer group, respectively.The difference in the 5-year OS between the two groups was statistically significant( P<0.05), while the difference in the 5-year DSS between the two groups was not statistically significant( P>0.05). Multivariate analysis by the Cox proportional hazard model showed that the independent risk factors for the prognosis of elderly patients with gastric cancer included the low-undifferentiated histological type of the tumor( P=0.004), the depth of tumor invasion pT stage of pT4a-pT4b( P=0.007), lymph node metastasis( P=0.034), tumor pTNM stage ⅢA-ⅢC( P=0.002)and vascular tumor thrombus( P=0.034).

Conclusions:

Elderly patients with gastric cancer have many preoperative co-existing diseases, which increases the risk of postoperative non-surgical complications.Therefore, we should focus on the peri-operative management of their comorbid diseases so as to improve the safety and efficacy of surgery.The advanced age is not the independent risk factors for the prognosis.
