Is surgery justified for elderly patients with extrahepatic cholangiocarcinoma? Reappraisal from a viewpoint of comorbidity and organ function

Perihilar cholangiocarcinoma resection: Is it beneficial for survival in elderly patients?

INTRODUCTION

As the population ages, surgeons are growing frequently faced with hard choices among a vast array of treatment options for the elderly. This study was to investigate safety and efficacy of resection in elderly patients with perihilar cholangiocarcinoma (PHCC).

PATIENTS AND METHODS

Literature reading and meta-analysis unveiled that elderly PHCC patients held a higher risk of death within 90 days after hepatectomy relative to younger patients, but their 5-year overall survival and disease-free survival were comparable. Among PHCC patients who underwent hepatectomy, the proportion of elderly patients with tumor classification Bismuth I-II and tumor stage pStage 1-3 was significantly higher than that of younger patients.

RESULTS

Curative resection R0 was more common in elderly patients than younger patients, but the difference was not statistically significant. Because of more comorbidities and less physiological reserve of elderly patients, they seemed to suffer more postoperative complications.

CONCLUSION

Considering improved life expectancy, it is crucial to treat elderly PHCC patients appropriately and attempts should be made to radical surgery based on comorbidities and functional status.

Diagnosis and Treatment of Perihilar Cholangiocarcinoma: A National Survey from the Korean Pancreatobiliary Association

Background/Aims

Based on their anatomy, cholangiocarcinomas (CCAs) are classified into intrahepatic, hilar, and distal CCAs. Although the diagnosis and treatment of each type of CCA are thought to be different, real-world data studies on the current practice are limited. Therefore, this study was designed to capture the current practice of diagnosing and treating perihilar CCA in Korea.

Methods

We conducted a survey using an online platform. The questionnaire consisted of 18 questions designed to evaluate the current practice of diagnosing and treating perihilar CCA in Korea. The targets of this survey were biliary endoscopists who are members of the Korean Pancreatobiliary Association.

Results

In total, 119 biliary endoscopists completed the survey. Of the respondents, 89.9% thought that the use of the International Classification of Diseases, 11th Revision (ICD-11) system is necessary to classify CCA. Approximately half of the respondents would recommend surgery or chemotherapy until patients were 80 years of age. For the pathological diagnosis of CCA, endoscopic retrograde cholangiopancreatography with biopsy was the most preferred modality. Routine preoperative biliary drainage was performed by 44.5% of the respondents. For operable CCAs, 64.7% of the respondents preferred endoscopic biliary drainage using plastic stents. For palliative biliary drainage, 69.7% of the respondents used plastic stents. For palliative endoscopic biliary drainage using metal stents, 63% of the respondents preferred the stent-in-stent method.

Conclusions

A new coding system using the ICD-11 is needed for classifying CCAs. Guidelines for diagnosing and treating CCA based on the clinical situation in Korea are needed.

Potential Role of Surgical Resection for Gallbladder Cancer in Elderly Patients

INTRODUCTION

With the aging of the population in Japan, gallbladder cancer (GBC) in the elderly is increasing. However, the available clinical data are limited, and the optimal treatment is still controversial. The aim of this study was to evaluate the benefit of surgical resection in GBC patients ≥75 years of age.

METHODS

A retrospective single center analysis of patients who had undergone surgical resection for GBC between 2000 and 2019 was carried out. Patients aged ≥75 years (elderly group, n = 24) or <75 years (younger group, n = 50) were compared.

RESULTS

Both younger and elderly patients exhibited similar clinicopathological characteristics, but comorbidity in the latter was significantly greater, as was the frequency of less invasive surgery. Nonetheless, the incidence of postoperative complications was similar in elderly and younger patients. The proportion of patients receiving adjuvant chemotherapy was lower in the elderly. Overall survival of elderly and younger patients was not significantly different (65.0 vs 62.4% at 5 years, P = .600). In multivariate analysis, residual tumor status but not age was an independent prognostic factor.

DISCUSSION

This study demonstrated that appropriate surgical treatment of elderly GBC patients was safe and effective, despite their having more comorbidities and lower rates of adjuvant chemotherapy than younger patients.
