Abstract
INTRODUCTION The scoping review was performed to identify methods of comorbidity assessment and to evaluate their significance in predicting the results of treatment of older patients undergoing elective abdominal surgeries for cancer. MATERIALS AND METHODS Ovid MEDLINE, Embase, CENTRAL, Web of Science, ClinicalTrials.gov and European Trials Register were searched for eligible studies investigating the impact of comorbidity on various postoperative outcomes of patients aged ≥65. Findings were narratively reported. RESULTS The review identified 40 studies with a total population of 59,612 patients, using eight different methods of comorbidity assessment. The most used was Charlson Comorbidity Index (60 % of studies) and presence of specific comorbid conditions (38 %). No study provided rationale for the choice of specific comorbidity measure. Most of the included studies reported short-term results (75 %), such as postoperative complications (43 %) and mortality (18 %) as main clinical endpoint. The results were inconsistent across the studies. DISCUSSION There is still no consensus regarding the choice of comorbidity measures and their role in postoperative outcome prediction. Further efforts are needed to develop new, well-designed, more effective comorbidity assessments tools.

Surgical options and survival prognosis in geriatric patients beyond average lifespan with locally advanced gastric cancer: a propensity score-matched analysis. Surg Endosc 2024; 38:2756-2769. [PMID: 38575830 DOI: 10.1007/s00464-024-10798-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 03/10/2024] [Indexed: 04/06/2024]
Abstract
BACKGROUND The appropriateness of laparoscopic gastrectomy (LG) for super-geriatric patients with locally advanced gastric cancer (LAGC) is inconclusive, and the prognostic factors are also yet to be elucidated. Herein, we aimed to investigate the surgical and oncological outcomes of LG versus open gastrectomy (OG) for geriatric patients with LAGC who have outlived the average lifespan of the Chinese population (≥ 78 years). METHODS This is a monocentric, retrospective, comparative study. A 1:1 propensity score matching (PSM) was performed to minimize selection bias and ensure well-balanced characteristics. The primary endpoint of interest was 3-year overall survival, while secondary endpoints included procedure-related variables, postoperative recovery indices, and complications. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify unfavorable prognostic factors. RESULTS Of 196 eligible individuals, 107 underwent LG and 89 underwent OG, with a median age (interquartile range [IQR]) of 82 [79, 84] years. PSM yielded 61 matched pairs, with comparable demographic and tumor characteristics. The LG group had a significantly lower overall complication rate than the OG group (31.1% vs. 49.2%, P = 0.042), as well as shorter duration of postoperative hospital stay [12 (11, 13) vs. 13 (12, 15.5) d, P < 0. 001], less intraoperative blood loss [95 (75, 150) vs. 230 (195, 290) mL, P < 0.001], but a longer operative time [228 (210, 255.5) vs. 196 (180, 219.5) min, P < 0.001]. The times to first aerofluxus, defecation, liquid diet, and half-liquid diet were comparable. Kaplan-Meier analyses revealed no significant difference in 3-year overall survival between the groups, either in the entire cohort or in subgroups with different TNM staging. Moreover, Age-adjusted Charlson Comorbidity Index scores of > 6 [hazard ratio (HR) 4.003; P = 0.021] and pathologic TNM stage III (HR 3.816, P = 0.023) were independent unfavorable prognostic factors for long-term survival. CONCLUSIONS LG performed by experienced surgeons offers the benefits of comparable or better surgical and oncological safety profiles than OG for super-geriatric patients with LAGC.

Abstract
This meta-analysis examined the surgical management of older patients (>80 years) with gastric cancer, who were often excluded from randomized controlled trials. We analyzed 23 retrospective cohort studies involving 18,372 patients and found that older patients had a higher in-hospital mortality rate (relative risk [RR], 3.23; 95% confidence interval [CI], 1.46-7.17; P<0.01) and more post-operative complications (RR, 1.36; 95% CI, 1.19-1.56; P<0.01) than did younger patients. However, the surgical complications were similar between the two groups. Older patients were more likely to undergo less extensive lymph node dissection and longer hospital stays. Although older patients had statistically significant post-operative medical complications, they were not deprived of surgery for gastric cancer. The comorbidities and potential risks of post-operative complications should be carefully evaluated in older patients, highlighting the importance of careful patient selection. Overall, this meta-analysis provides recommendations for the surgical management of older patients with gastric cancer. Careful patient selection and evaluation of comorbidities should be performed to minimize the risk of post-operative complications in older patients, while recognizing that they should not be deprived of surgery for gastric cancer.

Is Palliative Gastrojejunostomy for Malignant Gastric Outlet Obstruction an Optimal Choice for Very Elderly Patients? A Report from a Long-Lived Country. Ann Surg Oncol 2023; 30:313-321. [PMID: 36171530 DOI: 10.1245/s10434-022-12599-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 09/05/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Gastrojejunostomy (GJ) is a surgical option for malignant gastric outlet obstruction (mGOO). Confronting an aging society, the demand to treat elderly cancer patients with unresectable malignancies is increasing; however, the benefit of GJ to the very elderly (≥ 80 years of age) has never been investigated. METHODS This multicenter, retrospective review included 108 patients who had undergone GJ for mGOO from two medical centers in Japan, one of the most long-lived countries. Patients were divided into two groups, with 80 years of age as the cut-off. Various factors, including surgical complications and patient survival, were compared. RESULTS GJ in the very elderly (aged ≥ 80 years) was associated with a higher incidence of surgical complications (p = 0.049), such as delayed gastric emptying (DGE; p < 0.001), aspiration pneumonia (p = 0.029), and consequent mortality (p = 0.016). Age ≥80 years was also identified as an independent predictor of DGE (odds ratio 6.444, p = 0.005) and survival after GJ (hazard ratio 7.767, p = 0.016). In particular, the median survival time after GJ in the population aged ≥80 years with gastric cancer was only < 2 months. About the surgical procedure, antiperistaltic anastomosis with partial stomach partitioning (PSP) yielded the lowest occurrence rate of DGE (3.4%) and aspiration pneumonia (1.7%). CONCLUSIONS GJ does not seem to be the optimal choice for very elderly patients, particularly those with gastric cancer. If performed, antiperistaltic anastomosis with PSP should be employed to reduce the surgical complications.

Abstract
BACKGROUND It remains unclear whether laparoscopic gastrectomy with optimal lymphadenectomy is appropriate for very elderly patients with advanced gastric cancer. This study aimed to assess the validity of laparoscopic gastrectomy with D1+ lymphadenectomy performed for advanced gastric cancer in patients aged 80 years or more. METHODS Included in this retrospective study were 122 patients who underwent curative laparoscopic gastrectomy for advanced gastric cancer between 2013 and 2018. All patients over 80 years old underwent laparoscopic gastrectomy with D1+ lymphadenectomy. We divided patients by age between those who were very elderly (age ≥ 80 years; very elderly group [n = 57]) and those who were non-very elderly (age < 80 years; control group [n = 65]), and we compared patient and clinicopathological characteristics, intraoperative outcomes, and short- and long-term outcomes between the two groups. We also performed multivariate analyses to identify predictors of postoperative prognosis. RESULTS Eastern Cooperative Oncology Group Performance Status of grade 2 or higher and mean Charlson comorbidity index score and body mass index were significantly different between the very elderly group and the control group. Adjuvant chemotherapy was used in relatively few very elderly group patients. Operation time, blood loss volume, and postoperative morbidity and mortality did not differ between the two groups. The overall survival and disease-specific survival rate of very elderly group patients with the Charlson comorbidity index score of <3 was not significantly different from that of the control group patients. CONCLUSION The treatment of advanced gastric cancer by laparoscopic gastrectomy with D1+ lymphadenectomy to be both safe and effective in the very elderly group patients with the Charlson comorbidity index score of <3.

Abstract
BACKGROUND As the incidence of gastric cancer increases in elderly patients worldwide, laparoscopic gastrectomy (LG) for elderly patients with gastric cancer is also increasing. However, whether LG is an optimal surgical modality for elderly patients with gastric cancer remains unclear. This study aimed to evaluate the technical and oncological safety of LG for elderly patients ≥ 80 years old with gastric cancer. METHODS Patients who received curative gastrectomy for gastric cancer from 2003 to 2015 were enrolled in the study. They were divided into the LG in elderly patients aged over 80 years (LG-E) group, open gastrectomy (OG) in elderly patients (OG-E) group, and LG in non-elderly patients < 80 years (LG-NE) group. Patients' demographics and short- and long-term outcomes, such as postoperative complications and 5-year survival rate, were compared between the three groups, retrospectively. RESULTS The LG-E, OG-E, and LG-NE groups comprised 45, 43, and 329 patients, respectively. In the comparison between the LG-E and OG-E groups, the incidence of distal gastrectomy (DG) and the proportions of patients with pathological tumor stage T1, pathological N0, and final stage I were significantly higher in the LG-E versus OG-E group (89 vs. 56%, 76% vs. 16%, 82% vs. 37%, and 84% vs. 35%, p < 0.01, respectively). Blood loss and the incidence of overall postoperative complications in the LG-E group were significantly lower than those in the OG-E group (40 vs. 240 g, p < 0.01, and 29% vs. 53%, p < 0.05, respectively). Although the 5-year overall survival (OS) rate was not significantly different between the two groups, the 5-year disease-specific survival (DSS) rate was significantly higher in the LG-E group versus OG-E group (93% vs. 78%, p < 0.05). Overall comorbidities were significantly higher in the LG-E group versus LG-NE group, but there were no significant differences in short-term outcomes between the two groups. Further, although the 5-year OS rate was significantly lower in the LG-E group versus LG-NE group (67% vs. 87%, p < 0.01), there was no significant difference between the two groups in 5-year DSS rate. CONCLUSION LG is technically and oncologically safe for the treatment of gastric cancer in both elderly patients aged ≥ 80 years and the non-elderly and can be an optimal surgical modality for elderly patients with gastric cancer.

Abstract
BACKGROUND/AIM We aimed to assess the risk factors for postoperative complications and long-term outcome of patients aged ≥80 years after curative resection for gastric cancer (GC). PATIENTS AND METHODS Patients aged ≥80 years who underwent curative gastrectomy for stage I-III GC between 2013 and 2020 were included. Clinical factors were retrospectively analyzed. RESULTS Of all 109 patients, 29 (26.6%) had 33 postoperative complications (Clavien-Dindo grade ≥2). The rate of postoperative complications was higher in those with greater blood loss (≥170 ml, p<0.001). In multivariate analysis, greater blood loss was confirmed as an independent predictor of postoperative complications (p<0.001). The 30-day, 180-day, 1-year, and 3-year cumulative overall survival rates were 100%, 97.0%, 91.6%, and 74.7%, respectively. Multivariate analysis showed postoperative complications (p=0.014) and low prognostic nutritional index (PNI, p=0.044) were independent prognostic factors for poor overall survival. CONCLUSION Performing operations with less bleeding is important to reduce postoperative complications. According to the analysis of long-term survival, patients who experience postoperative complications and patients with a low preoperative PNI require special attention in the follow-up period. Nutritional support should be considered in patients with malnutrition.

Abstract
As the elderly population increases, the number of patients with gastric cancer has also been increasing. Elderly people have various preoperative problems such as malnutrition, high frequency of comorbidities, decreased performance status, and dementia. Furthermore, when surgery is performed, high postoperative complication rates and death from other diseases are also concerns. The goal of surgery in the elderly is that short-term outcomes are comparable to those in nonelderly, and long-term outcomes reach life expectancy. Perioperative problems in the elderly include: (1) Poor perioperative nutritional status; (2) Postoperative pneumonia; and (3) Psychological problems (dementia and postoperative delirium). Malnutrition in the elderly has been reported to be associated with increased postoperative complications and dementia, pointing out the importance of nutritional management. In addition, multidisciplinary team efforts, including perioperative respiratory rehabilitation, preoperative oral care, and early postoperative mobilization programs, are effective in preventing postoperative pneumonia. Furthermore, there are many reports on the usefulness of laparoscopic surgery for the elderly, and we considered that minimally invasive surgery would be the optimal treatment after assessing preoperative risk.
