Survival benefit of second line therapies for recurrent hepatocellular carcinoma: repeated hepatectomy, thermoablation and second-line transplant referral in a real life national scenario

BACKGROUND

Despite second-line transplant(SLT) for recurrent hepatocellular carcinoma(rHCC) leads to the longest survival after recurrence(SAR), its real applicability has never been reported. The aim was to compare the SAR of SLT versus repeated hepatectomy and thermoablation(CUR group).

METHODS

Patients were enrolled from the Italian register HE.RC.O.LE.S. between 2008 and 2021. Two groups were created: CUR versus SLT. A propensity score matching (PSM) was run to balance the groups.

RESULTS

743 patients were enrolled, CUR = 611 and SLT = 132. Median age at recurrence was 71(IQR 6575) years old and 60(IQR 53-64, p < 0.001) for CUR and SLT respectively. After PSM, median SAR for CUR was 43 months(95%CI = 37 - 93) and not reached for SLT(p < 0.001). SLT patients gained a survival benefit of 9.4 months if compared with CUR. MilanCriteria(MC)-In patients were 82.7% of the CUR group. SLT(HR 0.386, 95%CI = 0.23 - 0.63, p < 0.001) and the MELD score(HR 1.169, 95%CI = 1.07 - 1.27, p < 0.001) were the only predictors of mortality. In case of MC-Out, the only predictor of mortality was the number of nodules at recurrence(HR 1.45, 95%CI= 1.09 - 1.93, p = 0.011).

CONCLUSION

It emerged an important transplant under referral in favour of repeated hepatectomy or thermoablation. In patients with MC-Out relapse, the benefit of SLT over CUR was not observed.

The Effect of a Liver Transplant Program on the Outcomes of Resectable Hepatocellular Carcinoma: A Nationwide Multicenter Analysis

OBJECTIVE

To evaluate the effect of a liver transplantation (LT) program on the outcomes of resectable hepatocellular carcinoma (HCC).

BACKGROUND

Surgical treatment of HCC includes both hepatic resection (HR) and LT. However, the presence of cirrhosis and the possibility of recurrence make the management of this disease complex and probably different according to the presence of a LT program.

METHODS

Patients undergoing HR for HCC between January 2005 and December 2019 were identified from a national database of HCC. The main study outcomes were major surgical complications according to the Comprehensive Complication Index, posthepatectomy liver failure (PHLF), 90-day mortality, overall survival, and disease-free survival. Secondary outcomes were salvage liver transplantation (SLT) and postrecurrence survival.

RESULTS

A total of 3202 patients were included from 25 hospitals over the study period. Three of 25 (12%) had an LT program. The presence of an LT program within a center was associated with a reduced probability of PHLF (odds ratio=0.38) but not with overall survival and disease-free survival. There was an increased probability of SLT when HR was performed in a transplant hospital (odds ratio=12.05). Among transplant-eligible patients, those who underwent LT had a significantly longer postrecurrence survival.

CONCLUSIONS

This study showed that the presence of a LT program was associated with decreased PHLF rates and an increased probability to receive SLT in case of recurrence.

Liver resection of hepatocellular carcinoma in HIV-HCV co-infected patients: a retrospective case series

Introduction

Despite the effectiveness of new therapies and awareness campaigns, the number of seropositive patients is increasing every year. Recently, other causes of death, not directly related to HIV, have emerged, such as chronic liver disease. The risk of hepatocellular carcinoma (HCC) is seven times greater in HIV patients than in noninfected patients, and it is especially attributable to HCV infection. The aim of our study was to evaluate clinical outcomes of HCC in HIV-HCV co-infected patients after liver resection (LR).

Materials and methods

The current study was conducted on a prospective database and reviewed retrospectively. All consecutive patients with HCC treated by LR from January 2013 to March 2019 at the Luigi Sacco University Hospital in Milan were enrolled. We included patients older than 18 years of age with HCV-related HCC, and in this set of patients, we identified two groups based on the presence of HIV infection.

Results

We identified 16 patients with HCV infection and precisely five with HIV-HCV co-infection and eleven with HCV infection alone. All HIV patients were male against 72.7% in the non-HIV group (p = 0.509). All patients had optimal HIV virologic control and a normal CD4 T-cell count. The mean diagnosis-to-treatment interval was statistically different between the two groups (HIV versus non-HIV: 1.2 ± 0.55 months versus 2.39 ± 1.09 months, p = 0.039).

No other significant differences were found between HIV-HCV co-infected patients and HCV-infected patients. Long-term outcomes in terms of OS and RFS were similar between the two groups.

Conclusions

With a multidisciplinary approach and intensive support, LR can be a safe and efficacious procedure in HIV-HCV patients. For these reasons, we should not exclude potential patients merely on the basis of their HIV seropositivity.

Benchmarking postoperative outcomes after open liver surgery for cirrhotic patients with hepatocellular carcinoma in a national cohort

BACKGROUND

Benchmark analysis for open liver surgery for cirrhotic patients with hepatocellular carcinoma (HCC) is still undefined.

METHODS

Patients were identified from the Italian national registry HE.RC.O.LE.S. The Achievable Benchmark of Care (ABC) method was employed to identify the benchmarks. The outcomes assessed were the rate of complications, major comorbidities, post-operative ascites (POA), post-hepatectomy liver failure (PHLF), 90-day mortality. Benchmarking was stratified for surgical complexity (CP1, CP2 and CP3).

RESULTS

A total of 978 of 2698 patients fulfilled the inclusion criteria. 431 (44.1%) patients were treated with CP1 procedures, 239 (24.4%) with CP2 and 308 (31.5%) with CP3 procedures. Patients submitted to CP1 had a worse underlying liver function, while the tumor burden was more severe in CP3 cases. The ABC for complications (13.1%, 19.2% and 28.1% for CP1, CP2 and CP3 respectively), major complications (7.6%, 11.1%, 12.5%) and 90-day mortality (0%, 3.3%, 3.6%) increased with the surgical difficulty, but not POA (4.4%, 3.3% and 2.6% respectively) and PHLF (0% for all groups).

CONCLUSION

We propose benchmarks for open liver resections in HCC cirrhotic patients, stratified for surgical complexity. The difference between the benchmark values and the results obtained during everyday practice reflects the room for potential growth, with the aim to encourage constant improvement among liver surgeons.

Gastrointestinal tuberculosis presenting as acute abdomen: a case report

Intestinal tuberculosis (ITB) represents an important diagnostic challenge in the clinical setting, as it generally can occur as a chronic condition often mimicking other diseases such as Crohn’s disease (CD), and can present itself with acute onset, which can be life-threatening. A 29-years-old Chinese woman coming to ER with abdominal pain, fever and weight loss. Computed tomography and colonoscopy images were not diagnostic. Despite medical therapy, the patient progressively worsened developing sepsis requiring emergency surgery. Pathological and microbiological examination of the colon both pointed towards gastrointestinal tuberculosis involvement. Although ITB is generally a chronic-wasting condition, it can also occur as acute abdomen representing an absolute surgical emergency. Although caseation and necrosis in granulomas can be used for diagnosis of ITB, preoperative diagnosis is still challenging. Endoscopic biopsies targeted to ulcerous lesions could be an essential diagnostic tool, contrary to those targeted to the ulcers’ edges as performed in CD.

The Impact of Postoperative Ascites on Survival After Surgery for Hepatocellular Carcinoma: a National Study

BACKGROUND

Postoperative ascites (POA) is the most common complication after liver surgery for hepatocarcinoma (HCC), but its impact on survival is not reported. The aim of the study is to investigate its impact on overall survival (OS) and disease-free survival (DFS), and secondarily to identify the factors that may predict the occurrence.

METHOD

Data were collected from 23 centers participating in the Italian Surgical HCC Register (HE.RC.O.LE.S. Group) between 2008 and 2018. POA was defined as ≥500 ml of ascites in the drainage after surgery. Survival analysis was conducted by the Kaplan Meier method. Risk adjustment analysis was conducted by Cox regression to investigate the risk factors for mortality and recurrence.

RESULTS

Among 2144 patients resected for HCC, 1871(88.5%) patients did not experience POA while 243(11.5%) had the complication. Median OS for NO-POA group was not reached, while it was 50 months (95%CI = 41-71) for those with POA (p < 0.001). POA independently increased the risk of mortality (HR = 1.696, 95%CI = 1.352-2.129, p < 0.001). Relapse risk after surgery was not predicted by the occurrence of POA. Presence of varices (OR = 2.562, 95%CI = 0.921-1.822, p < 0.001) and bilobar disease (OR = 1.940, 95%CI = 0.921-1.822, p: 0.004) were predictors of POA, while laparoscopic surgery was protective (OR = 0.445, 95%CI = 0.295-0.668, p < 0.001). Ninety-day mortality was higher in the POA group (9.1% vs 1.9% in NO-POA group, p < 0.001).

CONCLUSION

The occurrence of POA after surgery for HCC strongly increases the risk of long-term mortality and its occurrence is relatively frequent. More efforts in surgical planning should be made to limit its occurrence.

Curative versus palliative treatments for recurrent hepatocellular carcinoma: a multicentric weighted comparison

BACKGROUND

Management of recurrence after surgery for hepatocellular carcinoma (rHCC) is still a debate. The aim was to compare the Survival after Recurrence (SAR) of curative (surgery or thermoablation) versus palliative (TACE or Sorafenib) treatments for patients with rHCC.

METHODS

This is a multicentric Italian study, which collected data between 2007 and 2018 from 16 centers. Selected patients were then divided according to treatment allocation in Curative (CUR) or Palliative (PAL) Group. Inverse Probability Weighting (IPW) was used to weight the groups.

RESULTS

1,560 patients were evaluated, of which 421 experienced recurrence and were then eligible: 156 in CUR group and 256 in PAL group. Tumor burden and liver function were weighted by IPW, and two pseudo-population were obtained (CUR = 397.5 and PAL = 415.38). SAR rates at 1, 3 and 5 years were respectively 98.3%, 76.7%, 63.8% for CUR and 91.7%, 64.2% and 48.9% for PAL (p = 0.007). Median DFS was 43 months (95%CI = 32-74) for CUR group, while it was 23 months (95%CI = 18-27) for PAL (p = 0.017). Being treated by palliative approach (HR = 1.75; 95%CI = 1.14-2.67; p = 0.01) and having a median size of the recurrent nodule>5 cm (HR = 1.875; 95%CI = 1.22-2.86; p = 0.004) were the only predictors of mortality after recurrence, while time to recurrence was the only protective factor (HR = 0.616; 95%CI = 0.54-0.69; p<0.001).

CONCLUSION

Curative approaches may guarantee long-term survival in case of recurrence.

Delayed presentation of blunt duodenal injuries in children. Case report and review of literature

BACKGROUND

Duodenal injuries are rare in children and classically present following a fall over the handle bar. Retroperitoneal location of the duodenum may lead to delay in diagnosis, and missed injuries are associated with increased morbidity and mortality.

CASE REPORT

A 5-year-old child was admitted to the National Trauma Center, in Tirana (Albania), 28 hours after a Motor Vehicle Crash (MVC), complaining of mild abdominal pain. He was febrile (39°C) and had a white blood cells count of 18,000 mm³. On physical exam he had mild tenderness. Plain abdominal X-rays and Focused Abdominal Sonography for Trauma (FAST) were negative for free air or free fluid. The CT scan of the abdomen demonstrated free air and fluid in the retroperitoneal space. At laparatomy, a perforation of the second portion of the duodenum was found. A single layer suture repair of the duodenum with wide drainage was performed. The patient was discharged from the hospital tolerating oral feeding 8 days later.

CONCLUSION

Duodenal injuries in children are rare. Most duodenal hematomas are managed non-operatively. This is a case of MCV with delayed presentation that was treated surgically for perforation successfully.

Surgical treatment of ulcerative colitis in the biologic therapy era

Recently introduced in the treatment algorithms and guidelines for the treatment of ulcerative colitis, biological therapy is an effective treatment option for patients with an acute severe flare not responsive to conventional treatments and for patients with steroid dependent disease. The reduction in hospitalization and surgical intervention for patients affected by ulcerative colitis after the introduction of biologic treatment remains to be proven. Furthermore, these agents seem to be associated with increase in cost of treatment and risk for serious postoperative complications. Restorative proctocolectomy with ileal pouch-anal anastomosis is the surgical treatment of choice in ulcerative colitis patients. Surgery is traditionally recommended as salvage therapy when medical management fails, and, despite advances in medical therapy, colectomy rates remain unchanged between 20% and 30%. To overcome the reported increase in postoperative complications in patients on biologic therapies, several surgical strategies have been developed to maintain long-term pouch failure rate around 10%, as previously reported. Surgical staging along with the development of minimally invasive surgery are among the most promising advances in this field.
