Surgery for gastric carcinoma in patients more than 85 years of age

Surgical oncology in patients aged 80 years and older is associated with increased postoperative morbidity and mortality: A systematic review and meta-analysis of literature over 25 years

BACKGROUND

The study aim is to analyze the evolution over the last 25 years of the results reported after abdominal oncological surgery in patients aged 80 years of age and older. The primary endpoint was morbidity and mortality in this group of patients; the secondary endpoint was overall survival.

METHODS

A systematic search strategy was used to browse through Medline/PubMed, EMBASE, Scopus, ClinicalTrials.gov, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials using a combination of standardized index terms. Studies published between 1997 and 2017 were selected. Only those studies that showed morbidity and mortality after digestive and hepatobiliary tract oncological surgery in individuals aged 80 years and older were included. The PROSPERO registration number is CRD42018087921. PRISMA and MOOSE guidelines were applied.

RESULTS

A total of 79 studies were included, categorized by origin of malignancy: esophageal (7), stomach (26), liver (4), pancreas (19), and colorectal (23). Compared with the non-elderly group, the elderly group had similar esophageal morbidity with higher mortality (RR 2.51, 1.50 to 4.21; P = 0.0005); higher gastric morbidity (RR 1.25, 1.09 to 1.43; P = 0.001), and mortality (RR 2.51, 1.81 to 3.49; P = 0.0001); similar liver morbidity and mortality; higher pancreatic morbidity (RR 1.17, 1.03 to 1.33; P = 0.02) and mortality (RR 2.37, 1.86 to 3.03; P < 0.00001); and similar colorectal morbidity with higher mortality (RR 4.44, 1.91 to 10.32; P = 0.005).

CONCLUSION

Oncological surgery of most abdominal visceral tumors is associated with increased morbidity and mortality in patients older than 80 years.

Incidence and risk factors of subsyndromal delirium after curative resection of gastric cancer

Background

Subsyndromal delirium, a condition in which patients exhibit some, but not all, of the symptoms of delirium, can negatively affect the outcomes of patients with cancer. However, the incidence of subsyndromal delirium in patients with gastric cancer is unknown. Here, we investigated the incidence and risk factors of subsyndromal delirium after curative resection of gastric cancer.

Methods

We recruited consecutive patients with gastric cancer who were scheduled for curative resection at a tertiary hospital. Patients’ subsyndromal delirium symptoms were serially assessed preoperatively and 1, 2, 3, and 7 days postoperatively using the Delirium Rating Scale-Revised-98 (DRS-R-98). A DRS-R-98 score of 8–14 at any postoperative assessment was considered to indicate subsyndromal delirium. Sociodemographic and pre−/intra-operative clinical data were also assessed. Logistic regression analyses were used to determine the associated risk factors.

Results

Data were analysed from 163 out of 217 eligible patients. Postoperative delirium occurred in one patient (0.6%) and subsyndromal delirium occurred in 19 patients (11.7%). Age ≥ 70 years (odds ratio, [OR] 3.85; 95% confidence interval [CI], 1.36–10.92; p = 0.011) and education level ≤ 9 years (OR, 3.98; 95% CI, 1.39–11.41; p = 0.010) were independent risk factors of subsyndromal delirium after adjusting for preoperative cognitive function. Other pre−/intra-operative variables including anxiety/depression, poor sleep quality, and anaesthesia duration were not associated with subsyndromal delirium.

Conclusions

In contrast to the low incidence of delirium among patients undergoing curative resection of gastric cancer, a substantial proportion of such patients experienced subsyndromal delirium. Considering the prognostic implications, more careful detection and management of subsyndromal delirium may be warranted in patients with gastric cancer.

The outcome of surgical treatment for elderly patients with gastric carcinoma

BACKGROUND

The aim of this study was to clarify the operative mortality and long-term survival of gastrectomy for elderly patients with gastric cancer.

METHODS

A total of 461 patients who underwent gastrectomy for gastric cancer in our hospital were classified as elderly group (≥80 years-old, 95 patients) and control group (60-69 years-old, 366 patients).

RESULTS

The frequency of comorbidities was significantly (P < 0.05) higher in elderly group (74.7%) than that in the control group (49.5%). No significant difference of the postoperative complication rate was found between the elderly group (23.2%) and the control group (23.2%). Adjuvant chemotherapy was 9.5% in the elderly group, which was significantly less than 29.0% of the control group (P < 0.05). Stage II and III elderly patients had worse disease specific survival (DSS) than controls did. In the elderly, overall survival (OS) was significantly worse than DSS in stage I patients (P < 0.05).

CONCLUSIONS

The operative complication rate of elderly patients was comparable to the control group. Comorbidity and occurrence of secondary malignant disease should be followed for elderly patients at stage I. For stage II and III disease patients, a novel drug which is acceptable for the elderly is needed as a postoperative therapy.

Clinicopathologic characteristics of serosa-positive gastric carcinoma in elderly patients

Purpose

The relationship between the prognosis and the age of patients with gastric carcinoma is controversial. This study examined the clinicopathologic features of elderly gastric carcinoma patients with serosal invasion.

Methods

We reviewed the hospital records of 136 elderly gastric carcinoma patients with serosal invasion retrospectively to compare the clinicopathologic findings in the elderly (aged > 70 years) and young (aged < 36 years).

Results

The 5-year survival rates of elderly and young patients with curative resection did not differ statistically (33.9% vs. 43.3%; P = 0.318). Multivariate analysis showed that two factors were independent, statistically significant parameters associated with survival: histologic type (risk ratio, 1.805; 95% confidence interval [CI], 1.041 to 3.132; P < 0.05) and operative curability (risk ratio, 2.506; 95% CI, 1.371 to 4.581; P < 0.01).

Conclusion

This study demonstrated that elderly gastric carcinoma patients with serosal invasion do not have a worse prognosis than young patients. The important prognostic factor was whether the patients underwent curative resection.

[Digestive surgery in the elderly]

The dramatic increase in digestive surgery among patients of advanced age is the logical consequence of the aging population demographics in developed countries. Surgery in the aged is not fundamentally different, but it demands precise and tailored assessment and management of surgical indications and surgical and anesthetic techniques. Advanced age is not a contraindication to even major digestive surgery, but every effort must be made to avoid urgent operations by attention to pre-existing symptoms which are all-too-often neglected in the aged. Intensive care may help to shorten the hospital stay which should ideally occupy only a minor portion of the numbered days of the patient (whose life expectancy may be significantly longer than one may intuitively foresee).

Clinicopathologic characteristics of gastric carcinoma in elderly patients: A comparison with young patients

AIM: To examine the clinicopathologic features of elderly patients with gastric carcinoma and to investigate the relationship between prognosis and age.

METHODS: We reviewed the hospital records of 2014 patients with gastric carcinoma retrospectively to compare the clinicopathologic findings in elderly (age >70 years) and young (age <36 years) patients during the period from 1986 to 2000 in a tertiary referral center in Gwangju, Korea. Overall survival was the main outcome measure.

RESULTS: Of the 2014 patients, 194 (9.6%) were in the elderly group and 137 (6.8%) were in the young group. The elderly and young patients had similar distributions with respect to depth of invasion, nodal involvement, hepatic metastasis, peritoneal dissemination, tumor stage at the initial diagnosis, and type of surgery. Synchronous multiple carcinomas were found in 14/194 (7.2%) of the elderly group and 4/137 (2.9%) of the young group (P<0.05). Using the Borrmann classification, type IV was more frequent in the young patients than in the elderly patients (P<0.05). Significantly more elderly patients had a well or moderately differentiated histology, and more young patients had a poorly differentiated histology and signet ring cell carcinoma (P<0.001). The 5-year survival rates of elderly and young patients did not differ statistically (52.8% vs 46.5%, P = 0.5290). Multivariate analysis showed that the histologic type, nodal involvement and operative curability were significant prognostic factors, and age itself was not an independent prognostic factor of survival for elderly gastric carcinoma patients.

CONCLUSION: Elderly patients with gastric carcinoma do not have a worse prognosis than young patients. The important prognostic factor is whether the patients undergo a curative resection.

Surgical resection for gastric cancer in elderly patients: is there a difference in outcome?

BACKGROUND

Early and long-term outcome of gastrectomy for gastric cancer in elderly adults has been a subject of controversy and debate.

MATERIALS AND METHODS

Clinical information was reviewed for patients undergoing gastrectomy for gastric cancer during an 11-year period (1990-2000) at the University of Tennessee Medical Center at Knoxville. Patient demographics, tumor characteristics, operative mortality and morbidity, survival, and length of hospitalization were reviewed.

RESULTS

Of 48 patients who underwent gastric resection for gastric adenocarcinoma, 24 were older than 70 and 24 younger than 70. There were no differences between the two groups regarding tumor characteristics, including location, tumor size, grade, gross pathology, lymph node involvement, lymphovascular invasion, and stage. In the elderly group, 75% underwent subtotal gastrectomy and 25% had total gastrectomy with or without resection of adjacent organs. In the younger patients, these numbers were 66.6% and 33.3%, respectively, which was statistically insignificant (P = 0.5). Five-year survival was 16.6% among elderly patients compared to 20.8% in the younger patients (P = 0.45). Half of the elderly patients and 39% of young patients had other comorbidities (P = 0.45). Postoperative mortality and morbidity was 8.33% and 33.3% in elderly patients, compared to 4.2% and 33.3%, respectively, in the younger group. These results were statistically insignificant (P = 0.4). The median postoperative length of stay was 15 days (95 percent confidence interval, 11-19 days) in younger patients compared to 18 days (95 percent confidence interval, 13-22 days) in the elderly group (P = 0.3).

CONCLUSION

This study suggests that gastrectomy can be carried out safely in elderly patients. The early and long-term outcomes in elderly patients (over age 70) are comparable to younger patients (under age 70). Age alone should not preclude gastric resection in elderly patients.
