Timing of Perioperative Chemotherapy Does Not Influence Long-Term Outcome of Patients Undergoing Combined Laparoscopic Colorectal and Liver Resection in Selected Upfront Resectable Synchronous Liver Metastases

Introduction. 60% of patients operated for colorectal liver metastases (CRLM) will develop recurrent disease and some may be candidates for a repeated liver resection. The study aimed to evaluate differences in intraoperative blood loss and complications comparing the primary and the repeated liver resection for metastases of colorectal cancer (CRC), as well as to evaluate differences in long-time follow-up.Method. 32 patients underwent 34 repeated liver resections due to recurrence of CRLM an studied retrospectively to identify potential differences between the primary and the repeat resections.Results. There was no 30-day postoperative mortality or postoperative hospital deaths. The median blood loss at repeat resection (1850 mL) was significantly (P=0.014) higher as compared to the primary liver resection (1000 mL). This did not have any effect on the rate of complications, even though increased bleeding in itself was a risk factor for complications. There were no differences in survival at long-term follow-up.Discussion. A repeated liver resection for CRLM was associated with an increased intraoperative bleeding as compared to the first resection. Possible explanations include presence of adhesions, deranged vascular anatomy, more complicated operations and the effects on the liver by chemotherapy following the first liver resection. 30 out of 32 patients had only one reresection of the liver.

Liver Resections

INTRODUCTION At present, liver resection offers the best long-term outcome and only chance for cure in patients with colorectal liver metastases. However, there are no large series that report the early and long-term outcomes of patients who require simultaneous diaphragm excision. This study was designed to investigate these patients. PATIENTS AND METHODS A total of 285 consecutive liver resections were performed over a 10-year period. Of these, 258 had liver resections alone and 27 underwent liver resection and simultaneous diaphragm excision. Data were collected prospectively and analysed retrospectively. Pre-operative assessment was standardised. The outcomes between the two groups were compared. RESULT There was no difference in age, hospital stay or intra-operative blood loss. The diaphragm was histologically involved in four out of 27 resections. As a result, the cancer involved resection margin incidence was greater in the liver resection and diaphragm excision group (14.8% versus 3.9%; P = 0.12). The median tumour size was also different between the two groups (60 mm versus 30 mm; P = 0.001). The liver and diaphragm resection group had a greater peri-operative complication rate (44.4% versus 21.3%; P = 0.02) and mortality (7.4% versus 1.6%; P = 0.25). Overall and disease-free survival was significantly worse in the group who underwent simultaneous diaphragm excision and liver resection (P = 0.04 and P = 0.005, respectively). Diaphragm invasion was found to be an independent predictor of poor overall outcome (P = 0.02). CONCLUSION Liver resection and simultaneous diaphragm excision have a greater incidence of peri-operative morbidity and mortality and a significantly worse long-term outcome compared with liver resection alone. However, these data suggest that liver resection in the presence of diaphragm invasion may still offer a favourable outcome compared with chemotherapy treatment alone. Therefore, we believe that diaphragm involvement by tumour should not be a contra-indication to hepatectomy.

Radiological Response

281 Background: The long-term outcome of patients resected for colorectal liver metastases (CLM) after neoadjuvant chemotherapy (CHT) depends by several tumoral and non-tumoral factors, such as the immune response to the tumor and to the CHT. The aim of this study was to investigate the impact of the pathological and immunological response in patients undergoing liver resection for CLM after CHT in regards to the long-term outcome. Methods: The immunoreactivity to CD3+ and NKp46+ cells inside the tumor, at the border between the tumor and the normal liver, and inside the normal liver was tested by computer-assisted image analyses in 121 patients undergoing liver resection for CLM between 2005 and 2013 preoperatively treated with oxaliplatin or irinotecan with or without bevacizumab or cetuximab. The survival was assessed in relation to several prognostic factors and to that immunoreactivity. Results: At univariate analysis T1/T2- and N0-status of the primary tumor, metachronous CLM, the radiological response, and the higher density of intratumoral CD3+ ( > 1%) and of NKp46+ (mean > 1) were found to be significantly associated with prolonged survival, but only intratumoral CD3+ ( > 1%) and NKp46+ (mean > 1) were significant on multivariate analysis (P = 0.005 and P = 0.004 respectively). On logistic regression analysis the metachronous CLM (OR = 2.781; P = 0.002), the use of irinotecan and cetuximab (OR = 3.891; P = 0.001) and the radiological response (OR = 3.219; P = 0.001) were found to be associated with increasing density of intratumoral CD3+ and NKp46+ cells. No significant associations were found with CLM number or size, CEA, or number of CHT courses. Combining the intratumoral CD3+ and NKp46+ cells density we defined four stages of survival (P = 0.003): patients presenting intratumoral CD3+ ( > 1%) and NKp46+ (mean > 1) had 100% overall survival at 5 years. Conclusions: Intratumoral CD3+ and NKp46+ cells density is a crucial prognostic factor in patients undergoing hepatic resection for CLM after CHT, and the kind of CHT seems related to their density. Further external validations are required to confirm our promising findings.
