Anatomic versus non-anatomic resection for early-stage intrahepatic cholangiocarcinoma: a propensity score matching and stabilized inverse probability of treatment weighting analysis. BMC Cancer 2023; 23:850. [PMID: 37697239 PMCID: PMC10496223 DOI: 10.1186/s12885-023-11341-z] [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: 03/23/2023] [Accepted: 08/26/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND Radical resection is still the most cost-effectiveness curative strategy for intrahepatic cholangiocarcinoma (ICC), but it remains controversial on the survival benefit of anatomic resection (AR). In this study, we sought to compare the oncologic outcomes between AR versus non-AR (NAR) as the primary treatment for early-stage ICC patients. METHODS Data of ICC patients who underwent hepatectomy and staged at AJCC I were retrospectively collected from 12 hepatobiliary centers in China between Dec 2012 and Dec 2015. Propensity score matching (PSM) and stabilized inverse probability of treatment weighting (IPTW) analysis were performed to minimize the effect of potential confounders, and the perioperative and long-term outcomes between AR and NAR groups were compared. RESULTS Two hundred seventy-eight ICC patients staged at AJCC I were eligible for this study, including 126 patients receiving AR and 152 patients receiving NAR. Compared to the NAR group, the AR group experienced more intraoperative blood loss before and after PSM or stabilized IPTW (all P > 0.05); AR group also experienced more intraoperative transfusion after stabilized IPTW (P > 0.05). In terms of disease-free survival (DFS) and overall survival (OS), no significant differences were observed between the two groups before and after PSM or stabilized IPTW (all P > 0.05). Multivariable Cox regression analyses found that AR was not an independent prognostic factor for either DFS or OS (all P > 0.05). Further analysis also showed that the survival benefit of AR was not found in any subgroup stratified by Child-Pugh grade (A or B), cirrhosis (presence or absence), tumor diameter (≤ 5 cm or > 5 cm) and pathological type (mass-forming or non-mass-forming) with all P > 0.05. CONCLUSION Surgical approach does not influence the prognosis of patients with stage I primary ICC, and NAR might be acceptable and oncological safety.

Abstract
BACKGROUND Despite retrospective studies comparing anatomical liver resection (AR) and non-anatomical liver resection (NAR), the efficacy and benefits of AR for hepatocellular carcinoma remain unclear. MATERIALS AND METHODS The authors systemically reviewed MEDLINE, Embase, and Cochrane Library for propensity score matched cohort studies that compared AR and NAR for hepatocellular carcinoma. Primary outcomes were overall survival (OS) and recurrence-free survival (RFS). Secondary outcomes were recurrence patterns and perioperative outcomes. RESULTS Overall, 22 propensity score matched studies (AR, n =2,496; NAR, n =2590) were included. AR including systemic segmentectomy was superior to NAR regarding the 3-year and 5-year OS. AR showed significantly better 1-year, 3-year, and 5-year RFS than NAR, with low local and multiple intrahepatic recurrence rates. In the subgroup analyses of tumour diameter less than or equal to 5 cm and tumours with microscopic spread, the RFS in the AR group was significantly better than that in the NAR group. Patients with cirrhotic liver in the AR group showed comparable 3-year and 5-year RFS with the NAR group. Postoperative overall complications were comparable between AR and NAR. CONCLUSIONS This meta-analysis demonstrated that AR showed better OS and RFS with a low local and multiple intra-hepatic recurrence rate than NAR, especially in patients with tumour diameter less than or equal to 5 cm and non-cirrhotic liver.

Oncological outcomes of anatomic versus non-anatomic resections for small hepatocellular carcinoma: systematic review and meta-analysis of propensity-score matched studies.

[PMID: 36117165 PMCID: PMC9484142 DOI: 10.1186/s12957-022-02770-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 09/11/2022] [Indexed: 11/17/2022] Open
Abstract
Background Primary liver cancer is the second-most commonly occurring cancer and has resulted in numerous deaths worldwide. Hepatic resection is of two main types, i.e., anatomic resection (AR) and non-anatomic resection (NAR). The oncological outcomes of hepatocellular carcinoma (HCC) patients after AR and NAR are still considered controversial. Therefore, we aimed to compare the impact of AR and NAR on the oncological outcomes of HCC patients with tumor diameters ≤ 5 cm using the propensity score matching method and research-based evidence. Method A systematic literature search was conducted. The main outcomes were disease-free survival (DFS), overall survival (OS), intrahepatic recurrence rate, and extrahepatic metastasis rate. Relative risk (RR) was calculated from forest plots and outcomes using random-effects model (REM). Result AR significantly improved DFS at 1, 3. and 5 years after surgery, compared to NAR (RR = 1.09, 95% CI = 1.04–1.15, P = 0.0003; RR = 1.16, 95% CI = 1.07–1.27, P = 0.0005; RR = 1.29, 95% CI = 1.07–1.55, P = 0.008). However, both of the difference in DFS at 7 years and OS at 1 and 3 years after AR versus that after NAR were not statistically significant. Nevertheless, the long-term OS associated with AR (5, 7, and 10 years) was superior to that associated with NAR (RR = 1.12, 95% CI = 1.03–1.21, P = 0.01; RR = 1.19, 95% CI = 1.04–1.36, P = 0.01; RR = 1.18, 95% CI = 1.05–1.34, P = 0.008). The difference in the intrahepatic recurrence rate after AR versus that after NAR was not statistically significant, but the extrahepatic metastasis rate after AR was significantly lower than that observed after NAR (RR = 0.61, 95% CI = 0.40–0.94, P = 0.03). Conclusion Therefore, AR should be the preferred surgical approach for HCC patients with tumor diameters ≤ 5 cm. Trial registration PROSPERO registration number CRD42022330596.

Laparoscopic Anatomical Versus Non-anatomical hepatectomy in the Treatment of Hepatocellular Carcinoma: A randomised controlled trial. Int J Surg 2022; 102:106652. [PMID: 35525414 DOI: 10.1016/j.ijsu.2022.106652] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 04/27/2022] [Accepted: 04/28/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND The choice of surgical modality for laparoscopic hepatectomy for hepatocellular carcinoma (HCC) has not been supported by high level of medical evidence hitherto. A prospective randomised controlled trial (RCT) was conducted to compare the perioperative and follow-up outcomes of patients with HCC treated by laparoscopic anatomical hepatectomy (LAH) and non-anatomical hepatectomy (LNAH). METHODS Between March 2013 and Jan 2018, eligible patients undergoing LAH and LNAH were enrolled and divided randomly into LAH group and LNAH group in this study. The perioperative and follow-up outcomes of both groups were compared and analyzed. RESULTS A total of 385 patients with HCC were randomly divided into LAH (n = 192) and LNAH (n = 193) groups. The groups were evenly matched for age, sex, liver background, segment involvement, tumor size, Child-Pugh grade and preoperative liver function. The operative time in the LAH group was longer than that of the LNAH group (p = 0.003). No significant between-group differences in intraoperative blood loss (p = 0.368), transfusion rate (p = 0.876), conversion to laparotomy rate (p = 0.365), overall complication rates (p = 0.054) were observed. The 1-year, 3-year and 5-year overall survival rates (OS) in the LAH group were 91.1%, 67.2%, 43.2%, respectively. The corresponding data in the LNAH group were 89.1%, 63.7%, and 35.2%, respectively. No significant difference was observed with regard to the 5-year OS rate (p = 0.054) between the two groups. The 1-year, 3-year and 5-year disease-free survival (DFS) rates in the LAH group were 87.0%, 54.7%, 33.9%, respectively. The corresponding data in LNAH group were 70.5%, 34.7%, and 30.1%, respectively. The 5-year DFS rate in the LAH group was significantly higher than that in the LNAH group (p = 0.009). CONCLUSIONS LAH versus LNAH for selected HCC patients was associated with increased DFS, lower intrahepatic ipsilateral recurrence rate, comparable long-term OS and postoperative complications. LAH is therefore recommended for selected HCC patients. REGISTRATION NUMBER NCT02009176 (https://www. CLINICALTRIALS gov/).

A Case-Matched Analysis of Laparoscopic Liver Resection for Hepatocellular Carcinoma Located in Posterosuperior Segments of the Liver According to Adaption of Developed Techniques. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58040543. [PMID: 35454381 PMCID: PMC9032568 DOI: 10.3390/medicina58040543] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 04/11/2022] [Accepted: 04/12/2022] [Indexed: 12/07/2022]
Abstract
Background and Objectives: Laparoscopic liver resection (LLR) for the hepatocellular carcinoma (HCC) located in posterosuperior (PS) segment is technically demanding, but has been overcome by accumulated experiences and technological improvements. We analyzed peri-and post-operative results before and after the adaptation of the enhanced techniques. Materials and Methods: We retrospectively reviewed 246 patients who underwent LLR for HCC in PS segments from September 2003 to December 2019. According to the introduction of advanced techniques including intercostal trocars, Pringle maneuver, and semi-lateral French position, the patients were divided into Group 1 (n = 43), who underwent LLR from September 2003 to December 2011, and Group 2 (n = 203), who underwent LLR from January 2012 to December 2019. Among these cases, 136 patients (Group 1 = 34, Group 2 = 102) were selected by case-matched analysis using perioperative variables. Results: Mean operation time (362 min vs. 291 min) and hospital stay (11 days vs. 8 days, p = 0.023) were significantly longer in Group 1 than Group 2. Otherwise, disease-free survival (DFS) rate was shorter and resection margin (1.3 mm vs. 0.7 mm, p = 0.034) were smaller in Group 2 than Group 1. However, there was no difference in type of complication (p = 0.084), severity of complication graded by the Clavien–Dindo grade system (p = 0.394), and 5-year overall survival (OS) rates (p = 0.986). In case-matched analysis, operation time (359 min vs. 266 min p = 0.002) and hospital stay (11.5 days vs. 8.0 days, p = 0.032) were significantly different, but there was no significant difference in resection margin, DFS, and OS. Conclusions: The adaptation of improved techniques has reduced the complexity of LLR in PS segments.

World J Gastrointest Oncol 2021; 13:1833-1846. [PMID: 34853654 PMCID: PMC8603461 DOI: 10.4251/wjgo.v13.i11.1833] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 05/08/2021] [Accepted: 07/13/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The long-term survival of patients with solitary hepatocellular carcinoma (HCC) following anatomical resection (AR) vs non-anatomical resection (NAR) is still controversial. It is necessary to investigate which approach is better for patients with solitary HCC.
AIM To compare perioperative and long-term survival outcomes of AR and NAR for solitary HCC.
METHODS We performed a comprehensive literature search of PubMed, Medline (Ovid), Embase (Ovid), and Cochrane Library. Participants of any age and sex, who underwent liver resection, were considered following the following criteria: (1) Studies reporting AR vs NAR liver resection; (2) Studies focused on primary HCC with a solitary tumor; (3) Studies reporting the long-term survival outcomes (> 5 years); and (4) Studies including patients without history of preoperative treatment. The main results were overall survival (OS) and disease-free survival (DFS). Perioperative outcomes were also compared.
RESULTS A total of 14 studies, published between 2001 and 2020, were included in our meta-analysis, including 9444 patients who were mainly from China, Japan, and Korea. AR was performed on 4260 (44.8%) patients. The synthetic results showed that the 5-year OS [odds ratio (OR): 1.19; P < 0.001] and DFS (OR: 1.26; P < 0.001) were significantly better in the AR group than in the NAR group. AR was associated with longer operating time [mean difference (MD): 47.08; P < 0.001], more blood loss (MD: 169.29; P = 0.001), and wider surgical margin (MD = 1.35; P = 0.04) compared to NAR. There was no obvious difference in blood transfusion ratio (OR: 1.16; P = 0.65) or postoperative complications (OR: 1.24, P = 0.18).
CONCLUSION AR is superior to NAR in terms of long-term outcomes. Thus, AR can be recommended as a reasonable surgical option in patients with solitary HCC.

Abstract
Laparoscopic liver resection (LLR) for Hepatocellular carcinoma (HCC) is a safe procedure. Repeat surgery is more often required, and the role of minimally invasive liver surgery (MILS) is not yet clearly defined. The present study analyzes data compiled by the Italian Group of Minimally Invasive Liver Surgery (IGoMILS) on LLR. To compare repeated LLR with the first LLR for HCC is the primary endpoint. The secondary endpoint was to evaluate the outcome of repeat LLR in the case of primary open versus primary MILS surgery. The data cohort is divided into two groups. Group 1: first liver resection and Group 2: Repeat LLR. To compare the two groups a 3:1 Propensity Score Matching is performed to analyze open versus MILS primary resection. Fifty-two centers were involved in the present study, and 1054 patients were enrolled. 80 patients underwent to a repeat LLR. The type of resection was different, with more major resections in the group 1 before matching the two groups. After propensity score matching 3:1, each group consisted of 222 and 74 patients. No difference between the two groups was observed. In the subgroup analysis, in 44 patients the first resection was performed by an open approach. The other 36 patients were resected with a MILS approach. We found no difference between these two subgroups of patients. The present study in repeat MILS for HCC using the IGoMILS Registry has observed the feasibility and safety of the MILS procedure.

Abstract
BACKGROUND/AIMS Liver stiffness measurement (LSM) by transient elastography (TE) has shown promising results for prediction of hepatocellular carcinoma (HCC) and hepatic decompensation in patients with chronic liver disease (CLD). However, whether prognostic performance of TE differs according to etiology or type of outcome remains further clarification. METHODS Performance of LSM for the prediction of HCC and hepatic decompensation was analyzed in a cohort of 4026 patients with asymptomatic CLD. RESULTS During median 4.5 years of follow-up (range 3.0-6.2 years), liver-related events (LRE) were observed in 196 patients (166 with HCC, 45 with hepatic decompensation, and 15 with both). In the multivariate analysis, LSM was independent factor associated with LRE and showed high AUROC (0.78). When stratified by type of outcome and etiology of liver disease, LSM showed high AUROC for the prediction of HCC for patients with non-viral hepatitis (0.89), while it showed relatively low AUROC for the prediction of HCC for patients with viral hepatitis (0.75). For the prediction of hepatic decompensation, LSM showed high AUROC for patients with both viral- and non-viral hepatitis (0.90, 0.90, respectively). CONCLUSIONS LSM showed powerful prognostic role for the prediction of LRE in patients with CLD. Notably, HCC risk was not negligible in patients with viral hepatitis who showed LSM value < 10 kPa, indicating watchful attention for HCC is still needed for viral hepatitis patients with low LSM.

Patterns, timing, and predictors of recurrence after laparoscopic liver resection for hepatocellular carcinoma: results from a high-volume HPB center. Surg Endosc 2021; 36:1215-1223. [PMID: 33620568 PMCID: PMC8758625 DOI: 10.1007/s00464-021-08390-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Accepted: 02/09/2021] [Indexed: 02/05/2023]
Abstract
Background Although long-term outcomes may be comparable between laparoscopic liver resection (LLR) and open liver resection (OLR) for hepatocellular carcinoma (HCC), there has been little discussion regarding the patterns of recurrence after LLR. Methods Patients with HCC who underwent hepatectomy between April 2015 and November 2018 were included in this study. The recurrence patterns were analyzed in detail. The recurrence outcomes following laparoscopic versus OLR for HCC were compared after 1:2 propensity score matching. Potential risk factors for recurrence were also assessed with Cox proportional risk models. Results Among 425 patients after LLR, 144 (33.8%) experienced recurrence at the last follow-up, with a median recurrence-free survival (RFS) of 10.0 months (range 1–58 months). The most frequent recurrence site was the liver (n = 99, 68.8%), followed by the surgical margin (n = 15, 10.4%) and distant metastases (n = 12, 8.3%). Liver recurrence with distant metastasis (n = 10, 6.9%) tended to occur early (median 8.0 months), while peritoneal recurrence (n = 8, 5.6%) occurred later (median 14.0 months). A total of 120 (83.3%) patients had recurrence within 2 years after LLR. No trocar site recurrence was observed in this study. The recurrence patterns, timing, and treatment did not show significant differences between the LLR and OLR. The independent risk factors for recurrence included ALBI grade, postoperative α-fetoprotein > 8 ng/ml, tumor size > 5 cm, surgical margin ≤ 1 cm, and multiple tumors. Patients with recurrence had 1- and 5-year overall survival rates of 81.1% and 60.7%, respectively, compared with rates of 95.8% and 92.9% for patients without recurrence (P < 0.000). Conclusion This study suggested that intrahepatic recurrence was still the most common recurrence pattern for HCC after LLR and that LLR did not increase the risk of trocar hole recurrence or implantation. Most cases of recurrence occurred within 2 years after LLR, suggesting that surveillance should be targeted to early recurrence.

Abstract
BACKGROUND LLR is widely adapted for HCC, while LLR in PS segments is still challenging. With recent improvement of techniques and accumulation of experiences, LLR in PS segments is feasible, but studies investigating the result after the modifications are lacking. METHODS In this single-center, retrospective study, 149 patients who underwent LLR for HCC located in PS segments from September 2003 to December 2016 were analyzed. The patients were divided into Group 1 (n=43) and Group 2 (n=106) who underwent LLR before and after 2012, respectively, when advanced techniques including use of intercostal trocars, Pringle maneuver, and semi-lateral position of patient were introduced. Also, these patients were compared with those who underwent open liver resection (OLR; n=124) for HCC in PS segments during the same period. RESULTS Mean operative time (394.7 minutes vs 331.2 minutes; P=0.013), intraoperative blood loss (1545.8 ml vs 1208.2 ml; P=0.020), and hospital stay (11.6 days vs 9.2, P<0.001) were significantly less in Group 2. Postoperative complication rate (18.6% vs 18.9%; P=0.970), open conversion rate (23% vs 17%; P=0.374), 5-year overall (79% vs 89%; P=0.607) and 5-year disease-free (52% vs 53%; P=0.657) survival rates were not significantly different between the groups. Compared to the OLR group, complication rate (40.3% vs 18.8%; P< 0.001) and hospital stay (17.6 days vs 9.7 days; P< 0.001) were significantly lower in the LLR group. CONCLUSION The complexity of LLR for HCC in PS segments is being gradually overcome by the introduction of advanced techniques.

Abstract
BACKGROUND The role of laparoscopically anatomical resection (LAR) for hepatocellular carcinoma (HCC) remains unclear due to the more demanding technique required in laparoscopy. This study is to analyze the clinical impact of LAR compared to laparoscopically non-anatomical resection (LNAR) for HCC. METHODS All patients received laparoscopic hepatectomy for HCC (diameter 5-10 cm) from January 2015 to December 2018 were retrospectively enrolled in this study. Patients were divided into LAR and LNAR groups. The perioperative and oncological outcomes were evaluated based on propensity score matching (PSM) method. RESULTS After PSM, 51 patients in each group were enrolled. The operative time in LAR group was longer (240 vs 195.0 min, p = 0.012) and blood loss was more (200.0 vs 150.0 mL, p = 0.030) than those of LNAR group, respectively. The total complication rates were comparable between them (21.6% vs 17.6%, p = 0.500). The 3-year overall survival rates were 59.4% in LAR group and 38.7% in LNAR group, respectively (p = 0.045). The 3-year disease-free survival rates were 52.3% in LAR group and 27.0% in LNAR group, respectively (p = 0.042). CONCLUSION LAR could be feasibly performed with comparable perioperative outcomes and contributed to improve long-term survival in patients with HCC (diameter 5-10 cm) when compared to LNAR.
