Hepatic resection for elderly patients with hepatocellular carcinoma: a systematic review of more than 17,000 patients

The Barthel Index predicts surgical textbook outcomes following hepatectomy for elderly patients with hepatocellular carcinoma: A multicenter cohort study

BACKGROUND

The burgeoning demand for hepatectomy in elderly patients with hepatocellular carcinoma (HCC) necessitates improved perioperative care. Geriatric populations frequently experience functional decline and frailty, predisposing them to adverse postoperative outcomes. The Barthel Index serves as a reliable measure for assessing functional capacity, and this study evaluates its impact on surgical textbook outcomes (TOs) in elderly HCC patients.

METHODS

A multicenter retrospective cohort study analyzed elderly patients (≥70 years) following hepatectomy for HCC between 2013 and 2021. Utilizing a Barthel Index cut-off value of 85, patients were divided into two groups: with and without preoperative functional decline and frailty. The primary outcome was the rate of TO, encompassing seven criteria. TO rates were compared between groups, and multivariate logistic regression analyses identified independent risks for achieving TOs.

RESULTS

Of 497 elderly patients, 157 (31.6 ​%) exhibited preoperative functional decline and frailty (Barthel Index score <85). The overall TO rate was 58.6 ​%. Patients with preoperative Barthel Index score <85 had significantly lower TO rates compared to patients with score ≥85 (29.3 ​% vs. 72.1 ​%, P ​< ​0.001). Multivariate analysis revealed preoperative Barthel Index score <85 as an independent risk for achieving TO (odds ratio 3.413, 95 ​% confidence interval 1.879-6.198, P ​< ​0.001). Comparable results were observed in the subgroups of patients undergoing open and laparoscopic hepatectomy.

CONCLUSION

Preoperative Barthel Index-based assessment of functional decline and frailty significantly predicts TOs following hepatectomy in elderly HCC patients, enabling identification of high-risk patients and informing preoperative management and postoperative care within geriatric oncology.

Impact of body mass index in elderly patients treated with laparoscopic liver resection for hepatocellular carcinoma

BACKGROUND

The impact of obesity on surgical outcomes in elderly patients candidate for liver surgery is still debated.

AIM

To evaluate the impact of high body mass index (BMI) on perioperative and oncological outcome in elderly patients (> 70 years old) treated with laparoscopic liver resection for hepatocellular carcinoma (HCC).

METHODS

Retrospective multicenter study including 224 elderly patients (> 70 years old) operated by laparoscopy for HCC (196 with a BMI < 30 and 28 with BMI ≥ 30), observed from January 2009 to January 2019.

RESULTS

After propensity score matching, patients in two groups presented comparable results, in terms of operative time (median range: 200 min vs 205 min, P = 0.7 respectively in non-obese and obese patients), complications rate (22% vs 26%, P = 1.0), length of hospital stay (median range: 4.5 d vs 6.0 d, P = 0.1). There are no significant differences in terms of short- and long-term postoperative results.

CONCLUSION

The present study showed that BMI did not impact perioperative and oncologic outcomes in elderly patients treated by laparoscopic resection for HCC.

Selective internal radiation therapy in older patients with hepatocellular carcinoma: a retrospective analysis

BACKGROUND

Selective internal radiation therapy (SIRT) is applied to hepatocellular carcinoma (HCC), a disease with increased incidence in the elderly. However, SIRT has rarely been specifically studied in elderly population. The aim of this study was to investigate efficacy and safety of SIRT in elderly HCC patients.

METHODS

We studied retrospectively data from patients treated with SIRT for HCC. Clinical and laboratory data were retrieved. We used 70-years old as threshold between younger and elderly populations, to compare outcomes.

RESULTS

A total of 222 patients treated with SIRT for HCC were studied, of which 134 patients were younger and 88 older. Median overall survival (OS) was not significantly different between younger and elderly group: 15.6 months (95% CI, 11.7-19.5) and 14.8 months (95% CI, 9.4-20.3) (P = 0.86). Age was not associated with OS in multivariable analysis, with a Hazard ratio of 1.09 (95% CI, 0.82-1.45, P = 0.55). Results of progression-free survival and responses were also similar in both groups. Toxicities were similar between the two groups, including the occurrence of radioembolization-induced liver disease (11.5 vs. 11.4%, P = 0.97).

CONCLUSION

SIRT appears to be a well-tolerated treatment with the same efficacy in elderly compared to younger patients in HCC. Our study is the first to study its impact with glass microspheres. This warrants confirmation in large prospective studies.

OUP accepted manuscript

Background

The efficacy of repeat hepatic resection (rHR) in the treatment of recurrent hepatocellular carcinoma compared with radiofrequency or microwave ablation after resection of the primary tumour remains controversial. A systematic review and meta-analysis were performed to compare the safety and efficacy of these procedures.

Methods

PubMed, Embase, Scopus, Cochrane Library, and China National Knowledge Infrastructure databases were systematically searched to identify related studies published before 10 October 2021. Overall and recurrence-free survival after different treatments were compared based on pooled hazard ratios with a random-effects model.

Results

Two randomized clinical trials and 28 observational studies were included, involving 1961 and 2787 patients who underwent rHR and ablation respectively. Median perioperative mortality in both groups was zero but patients in the rHR group had higher median morbidity rates (17.0 per cent) than those in the ablation group (3.3 per cent). rHR achieved significantly longer recurrence-free survival than ablation (HR 0.79, 95 per cent c.i. 0.70 to 0.89, P < 0.001), while both groups had similar overall survival (HR 0.93, 95 per cent c.i. 0.83 to 1.04, P = 0.18).

Conclusion

rHR and ablation based on radio- or microwaves are associated with similar overall survival in patients with recurrent hepatocellular carcinoma after resection of the primary tumour.

Radiofrequency ablation vs surgical resection in elderly patients with hepatocellular carcinoma in Milan criteria

BACKGROUND

Surgical resection and radiofrequency ablation (RFA) represent two possible strategy in treatment of hepatocellular carcinoma (HCC) in Milan criteria.

AIM

To evaluate short- and long-term outcome in elderly patients (> 70 years) with HCC in Milan criteria, which underwent liver resection (LR) or RFA.

METHODS

The study included 594 patients with HCC in Milan criteria (429 in LR group and 165 in RFA group) managed in 10 European centers. Statistical analysis was performed using the Kaplan-Meier method before and after propensity score matching (PSM) and Cox regression.

RESULTS

After PSM, we compared 136 patients in the LR group with 136 patients in the RFA group. Overall survival at 1, 3, and 5 years was 91%, 80%, and 76% in the LR group and 97%, 67%, and 41% in the RFA group respectively (P = 0.001). Disease-free survival at 1, 3, and 5 years was 84%, 60% and 44% for the LR group, and 63%, 36%, and 25% for the RFA group (P = 0.001).Postoperative Clavien-Dindo III-IV complications were lower in the RFA group (1% vs 11%, P = 0.001) in association with a shorter length of stay (2 d vs 7 d, P = 0.001).In multivariate analysis, Model for End-stage Liver Disease (MELD) score (> 10) [odds ratio (OR) = 1.89], increased value of international normalized ratio (> 1.3) (OR = 1.60), treatment with radiofrequency (OR = 1.46) ,and multiple nodules (OR = 1.19) were independent predictors of a poor overall survival while a high MELD score (> 10) (OR = 1.51) and radiofrequency (OR = 1.37) were independent factors associated with a higher recurrence rate.

CONCLUSION

Despite a longer length of stay and a higher rate of severe postoperative complications, surgery provided better results in long-term oncological outcomes as compared to ablation in elderly patients (> 70 years) with HCC in Milan criteria.

Short- and Long-Term Outcomes After Hepatectomy in Elderly Patients with Hepatocellular Carcinoma: An Analysis of 229 Cases from a Developing Country

Background

The number of elderly patients with HCC who undergo liver resection is increasing. Because of the advanced age of the patients, increased postoperative morbidity and reduced overall survival are expected in this population. The study aim was to compare clinicopathologic and operative features, short- and long-term outcomes among hepatocellular carcinoma (HCC) patients from three age groups undergoing potentially curative liver resection in a developing country.

Methods

Prospectively collected data relating to 229 patients who underwent curative-intent liver resection from January 2009 until December 2018 were analyzed. The patients were divided into two age groups: G1 was below 70 years old (n=151) and G2 was 70 years old and older (n=78). Demographic, clinical, operative data, short- and long-term outcomes were compared between the two groups. Univariate and multivariate analyses of prognostic factors were performed.

Results

The mean overall morbidity rate of the patients was 31.1% (G1), and 46.2% (G2) by age group. Postoperative morbidity was significantly higher in the G2 group (p=0.03). There was no difference in major morbidity between the two groups (p=0.214). No significant difference in mortality rate and overall survival was found between the study groups (p=0.280, p=0.383). Both age ≥70 years (ie, G2 group) and liver cirrhosis were identified as prognostic factors for postoperative morbidity, and a Child-Pugh score B as a negative prognostic factor for overall survival. In subgroup analysis of patients with cirrhosis, age ≥70, diabetes mellitus and perioperative transfusion were identified as prognostic factors for postoperative morbidity.

Conclusion

The study confirmed the safety and feasibility of liver resection in elderly patients with HCC. However, appropriate patient selection among the elderly is mandatory in order to improve short- and long-term outcomes.

Therapeutic Decision Making in Hepatocellular Carcinoma According to Age and Child-Pugh Class: A Nationwide Cohort Analysis in South Korea

Background

We sought to analyze the preferred treatment modality by age and liver function in South Korea.

Methods

The Korean Liver Cancer Study Group randomly extracted the data of patients with hepatocellular carcinoma (HCC) enrolled in the Korean Central Cancer Registry from 2008 to 2014 from approximately 50 hospitals nationwide. After excluding distant and lymphatic metastases, the treatment preference for patients with a single lesion (excluding PVT (portal vein thrombosis), hepatic vessels, and bile duct invasion) and with PVT was evaluated in 7559 patients. Patients were grouped by age, and baseline liver function was divided based on the Child-Pugh class (CPC) A, B, and C.

Results

For a single HCC, the majority of patients selected transarterial therapy as the initial treatment, followed by surgical resection and local ablative therapy. The surgical resection rate decreased significantly with age (p < 0.001), and the transarterial therapy rate significantly increased (p < 0.001). For CPC C, liver transplantation was significantly increased to 11.5%, and 36.3% of patients received no treatment. In HCC with PVT, the transarterial therapy rate was the highest, followed by the rate of abandonment of treatment. The proportion of no treatment significantly increased with age (p < 0.001). In CPC C, transarterial therapy and systemic therapy were attempted in 15.4% and 5.8% of patients, respectively.

Conclusions

Age and liver function have a significant impact on the therapeutic decision-making of HCC patients in Korea. In unfavorable conditions, surgical resection was less favored in patients with single tumors, and no treatment was preferred in patients with PVT.

Multicenter analysis of long-term oncologic outcomes of hepatectomy for elderly patients with hepatocellular carcinoma

BACKGROUND

Aging of the population and prolonged life expectancy have significantly increased the number of elderly patients undergoing hepatectomy for hepatocellular carcinoma (HCC). However, potential benefits, especially long-term oncologic outcomes of hepatectomy for elderly patients with HCC remain unclear.

METHOD

Patients treated with curative-intent hepatectomy for HCC in 8 Chinese hospitals were enrolled. Patients were divided into the elderly (≥70 years old) and younger (<70 years old) groups. Overall survival (OS), cancer-specific survival (CSS), and time-to-recurrence (TTR) were compared. Risk factors of CSS and TTR were evaluated by univariable and multivariable competing-risk regression analyses.

RESULTS

Of 2134 patients, 259 (12.1%) and 1875 (87.9%) were elderly and younger aged, respectively. Postoperative 30-day and 90-day mortality was comparable among elderly and younger patients. Compared with younger patients, the elderly had a worse 5-year OS (49.4% vs. 55.3%, P = 0.032), yet a better 5-year CCS (74.5% vs. 61.0%, P = 0.005) and a lower 5-year TTR (33.7% vs. 44.9%, P < 0.001), respectively. Multivariable analyses identified that elder age was independently associated with more favorable CSS (HR 0.74, 95%CI 0.58-0.90, P = 0.011) and TTR (0.69, 0.53-0.88, P < 0.001) but was not associated with OS (P = 0.136).

CONCLUSIONS

Age by itself is not a contraindication to surgery, and selected elderly patients with HCC can benefit from hepatectomy. Compared with younger patients, elderly patients have noninferior oncologic outcomes following hepatectomy for HCC.

Major Hepatectomy in Elderly Patients with Large Hepatocellular Carcinoma: A Multicenter Retrospective Observational Study

Background

With an increase in life expectancy and improvement of surgical safety, more elderly patients with hepatocellular carcinoma (HCC), even with large tumors, are now considered for hepatectomy. This study aimed to clarify the impact of age on short- and long-term outcomes after major hepatectomy (≥3 segments) for large HCC (≥5 cm).

Patients and Methods

Using a multicenter database, patients who underwent curative-intent major hepatectomy for large HCC between 2006 and 2016 were identified. Postoperative morbidity and mortality, overall survival (OS) and recurrence-free survival (RFS) were compared between the elderly (≥65 years) and younger (<65 years) patients. Univariable and multivariable Cox-regression analyses were performed to identify the risk factors of OS and RFS in the entire and elderly cohorts, respectively.

Results

Of 830 patients, 92 (11.1%) and 738 (88.9%) were elderly and younger patients, respectively. There were no significant differences in postoperative 30-day mortality and morbidity between the two groups (5.4% vs 2.6% and 43.5% vs 38.3%, both P>0.05). The 5-year OS and RFS rates in elderly patients were also comparable to younger patients (35.0% vs 33.2% and 20.0% vs 20.8%, both P>0.05). In the entire cohort, multivariable Cox-regression analyses identified that old age was not independently associated with OS and RFS. However, in the elderly cohort, preoperative alpha-fetoprotein level >400 μg/L, multiple tumors, macrovascular invasion and microvascular invasion were independently associated with decreased OS and RFS.

Conclusion

Carefully selected elderly patients benefited from major hepatectomy for large HCC as much as younger patients, and their long-term prognosis was determined by preoperative alpha-fetoprotein level, tumor number and presence of macro- or micro-vascular invasion.

Hepatocellular carcinoma in old age: are there any benefits of liver resection in old age?

Purpose

Elderly individuals have comorbidities that can adversely affect surgical outcomes. Some studies reported that elderly patients with hepatocellular carcinoma (HCC) have higher liver- and non-liver-related deaths. Therefore, palliative treatments are preferred in these patients. We compared surgical treatment outcomes between young and old age groups.

Methods

In total, 233 liver resections were performed in patients with HCC from March 2012 to December 2018. We retrospectively reviewed medical records. The old age group was defined as patients aged more than 70 years. We compared perioperative characteristics and surgical outcomes and analyzed the prognostic factors for disease-free survival (DFS) and overall survival (OS) rates.

Results

The young and old age group included 184 and 49 patients, respectively. Preoperative characteristics were similar. Major liver resection rate was similar (young age group, 26.1% vs. old age group, 20.4%), but the operation time was a little bit shorter in old age group. Major postoperative complications were 23 (12.5%) and 9 (18.4%) in the young and old age group (P = 0.351). Median non-liver-related overall survival were 80 and 76 months (P = 0.889) and liver-related OS were 76 and 76 months (P = 0.514) in the young and old age groups, respectively. Age was not an independent risk factor for DFS and OS.

Conclusion

Elderly patients showed similar non-liver- and liver-related OS rates as young patients after liver resection. Postoperative complications were also similar. If elderly patients are well selected, they can receive curative treatment and show good surgical outcomes.

High expression levels of CLEC4M indicate poor prognosis in patients with hepatocellular carcinoma

The identification of novel and accurate biomarkers is important to improve the prognosis of patients with hepatocellular carcinoma (HCC). C-Type lectin domain family 4 member M (CLEC4M) is involved in the progression of numerous cancer types. However, the clinical significance of CLEC4M in HCC is yet to be elucidated. The aim of the present study is to evaluate the involvement of CLEC4M in HCC progression. The expression level of CLEC4M was determined in tumor, and their corresponding adjacent non-tumor tissues derived from 88 patients with HCC, using immunohistochemistry, western blot and reverse transcription-quantitative PCR. The correlation between CLEC4M expression and certain clinicopathological characteristics was retrospectively analyzed. The results suggested that CLEC4M was specifically labeled in sinusoidal endothelial cells, in both HCC and non-tumor tissues. Moreover, the expression of CLEC4M in tumor tissues was significantly lower than that in non-tumor tissues (P<0.0001), which indicated its potential as a biomarker of the development of HCC. Subsequently, correlation analysis suggested that the relatively higher CLEC4M expression in HCC tissues was significantly associated with increased microvascular invasion (P=0.008), larger tumor size (P=0.018), absence of tumor encapsulation (P<0.0001) and lower tumor differentiation (P=0.019). Notably, patients with high CLEC4M expression levels in their tumor tissues experienced more frequent recurrence and shorter overall survival (OS) times compared with the low-expression group. Furthermore, CLEC4M expression in tumor tissues was identified as an independent and significant risk factor for recurrence-free survival and OS. The results of the present study suggest that CLEC4M may be a valuable biomarker for the prognosis of the patients with HCC, postoperatively.

Serum Prealbumin is Negatively Associated with Survival in Hepatocellular Carcinoma Patients after Hepatic Resection

Objective: Low serum prealbumin levels are associated with poor prognoses in some type of cancers. However, the role of prealbumin in patients with hepatocellular carcinoma (HCC) is unknown. The present study aimed to investigate the role of serum prealbumin levels in long-term survival for HCC patients after hepatic resection.

Methods: HCC patients who underwent hepatic resection from June 2007 to December 2015 were retrospectively analyzed in a tertiary liver center. Patients were classified as having normal or reduced serum prealbumin based on a cut-off value of 200 mg/L. Overall survival and recurrence rate were analyzed between groups. Propensity score analysis was used to reduce bias due to other patient differences at baseline.

Results: A total of 1349 HCC patients who underwent hepatic resection were enrolled on this study, including 1168 (86.6%) male and 181 (13.4%) female. Patients with normal serum prealbumin had significantly higher overall survival than those with reduced serum prealbumin (P < 0.001). Similar findings were observed after propensity analysis and subgroup analysis based on liver cirrhosis. Moreover, patients with normal serum prealbumin had a significantly lower recurrence rate than those with reduced serum prealbumin (P < 0.001).

Conclusions: Low preoperative level of serum prealbumin is associated with poor long-term survival in patients with HCC after hepatic resection. Low serum prealbumin may be a marker to identify patients at high risk of poor prognosis after hepatic resection.
