Survival Impact of Primary Tumor Lymph Node Status and Circulating Tumor Cells in Patients with Colorectal Liver Metastases
Laparoscopic liver resection for non-colorectal non-neuroendocrine metastases: perioperative and oncologic outcomes
Background
Liver resection is a treatment of choice for colorectal and neuroendocrine liver metastases, and laparoscopy is an accepted approach for surgical treatment of these patients. The role of liver resection for patients with non-colorectal non-neuroendocrine liver metastases (NCNNLM), however, is still disputable. Outcomes of laparoscopic liver resection for this group of patients have not been analyzed.
Material and methods
In this retrospective study, patients who underwent laparoscopic liver resection for NCNNLM at Oslo University Hospital between April 2000 and January 2018 were analyzed. Perioperative and oncologic data of these patients were examined. Postoperative morbidity was classified using the Accordion classification. Kaplan–Meier method was used for survival analysis. Median follow-up was 26 (IQR, 12–41) months.
Results
Fifty-one patients were identified from a prospectively collected database. The histology of primary tumors was classified as adenocarcinoma (n = 16), sarcoma (n = 4), squamous cell carcinoma (n = 4), melanoma (n = 16), gastrointestinal stromal tumor (n = 9), and adrenocortical carcinoma (n = 2). The median operative time was 147 (IQR, 95–225) min, while the median blood loss was 200 (IQR, 50–500) ml. Nine (18%) patients experienced postoperative complications. There was no 90-day mortality in this study. Thirty-five (68%) patients developed disease recurrence or progression. Seven (14%) patients underwent repeat surgical procedure for recurrent liver metastases. One-, three-, and five-year overall survival rates were 85%, 52%, and 38%, respectively. The median overall survival was 37 (95%CI, 25 to 49) months.
Conclusion
Laparoscopic liver resection for NCNNLM results in good outcomes and should be considered in patients selected for surgical treatment
Laparoscopic Resection of Recurrence from Hepatocellular Carcinoma after Liver Transplantation: Case Reports and Review of the Literature
Background. Recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) indicates a poor prognosis. Surgery is considered the only curative option for selected patients with HCC recurrence following LT. Traditionally, the preference is given to the open approach. Methods. In this report, we present two cases of laparoscopic resections (LR) for recurrent HCC after LT, performed at Oslo University Hospital, Rikshospitalet. Results. Both procedures were executed without intraoperative and postoperative adverse events. Whereas one of the patients had a recurrence one year after LR, the other patient did not have any sign of disease during 3-year follow-up. Conclusions. We argue that, in selected cases, patients with HCC recurrence following LT may benefit from LR due to its limited tissue trauma and timely start of subsequent treatment if curative resection cannot be obtained. In patients with relatively favorable prognosis, LR facilitates postoperative recovery course and avoids unnecessary laparotomy
The New National Registry for Gastrointestinal Surgery in Norway: NoRGast
Background and aims: There is an increasing demand for high-quality data for the outcome of health care. Diseases of the gastro-intestinal tract involve large patient groups often presenting with serious or life-threatening conditions. Complications may affect treatment outcomes and lead to increased mortality or reduced quality of life. A continuous, risk-adjusted monitoring of major complications is important to improve the quality of health care to patients undergoing gastrointestinal resections. We present the development of the Norwegian Registry for Gastrointestinal Surgery, a national registry for colorectal, upper gastrointestinal, and hepato-pancreato-biliary resections in Norway.
Materials and methods: A narrative and qualitative presentation of the development and current state of the registry.
Results: We present the variables and the analysis tools and provide examples for the potential in quality improvement and research. Core characteristics include a strictly limited set of variables to reflect important risk factors, the procedure performed, and the clinical outcomes.
Conclusion: A registry with the potential to present complete national cohort data is a powerful tool for quality improvement and research.The author(s) disclosed receipt of the following financial

Laparoscopic parenchyma-sparing liver resection for colorectal metastases
Laparoscopic liver resection (LLR) of colorectal liver metastases (CLM) is increasingly performed in specialized centers. While there is a trend towards a parenchyma-sparing strategy in multimodal treatment for CLM, its role is yet unclear. In this study we present short- and long-term outcomes of laparoscopic parenchyma-sparing liver resection (LPSLR) at a single center
Short-term outcomes after elective colon cancer surgery: an observational study from the Norwegian registry for gastrointestinal and HPB surgery, NoRGast
Background: To describe the real burden of major complications after elective surgery for colon cancer in Norway, and to assess which predictors that are significantly associated with the short-term outcome.
Methods: An observational, multi-centre analysis of prospectively registered colon resections registered into the Norwegian Registry for Gastrointestinal Surgery, NoRGast, between January 2014 and December 2016. A propensity score-adjusted subgroup analysis for surgical access groups was attempted, with laparoscopic resections grouped as intention-to-treat.
Results: Out of 1812 resections, 14.0% of patients experienced a major complication within 30 days following surgery. The over-all reoperation rate was 8.7%, and rate of reoperation for anastomotic leak was 3.8%. Twenty patients (1.1%) died within 30 days after surgery. Higher age was not a significant predictor of major complications, including 30-day mortality. After correction for all co-variables, open access surgery was associated with higher rates of major complications (OR 1.67 (CI 1.22-2.29), p = 0.002), higher 30-day mortality (OR 4.39 (CI 1.19-16.13) p = 0.026) and longer length-of-stay (HR 0.58 (CI 0.52-0.65) p < 0.001).
Conclusions: Our results indicate a low complication burden and high rate of uneventful patient journeys after elective surgery for colon cancer in Norway. Age was not associated with higher morbidity or mortality rates. Open access surgery was associated with an inferior short-term outcome
Impact of early disease progression and surgical complications on adjuvant chemotherapy completion rates and survival in patients undergoing the surgery first approach for resectable pancreatic ductal adenocarcinoma – A population-based cohort study
Heterogeneous radiological response to neoadjuvant therapy is associated with poor prognosis after resection of colorectal liver metastases
Introduction
Surgery combined with perioperative chemotherapy has become standard of care in patients with resectable colorectal liver metastases. However, poor outcome is expected for a significant subgroup. The clinical implications of inter-metastatic heterogeneity remain largely unknown. In a prospective, population-based series of patients undergoing resection of multiple colorectal liver metastases, the aim was to investigate the prevalence and prognostic impact of heterogeneous response to neoadjuvant chemotherapy.
Materials and Methods
Radiological response to treatment was evaluated in a lesion-specific manner in 2–5 metastases per patient. Change of lesion diameter was evaluated and response/progression was classified according to three different size thresholds; 3, 4 and 5 mm. A heterogeneous response was defined as progression and response of different metastases in the same patient.
Results
In total, 142 patients with 585 liver metastases were examined with the same radiological method (MRI or CT) before and after neoadjuvant treatment. Heterogeneous response to treatment was seen in 16 patients (11%) using the 3 mm size change threshold, and this group had a 5-year cancer-specific survival of 19% compared to 49% for patients with response in all lesions (p = 0.003). Cut-off values of 4–5 mm were less sensitive for detecting a heterogeneous response, but the survival difference was similar and significant.
Conclusion
A subgroup of patients with multiple colorectal liver metastases had heterogeneous radiological response to neoadjuvant chemotherapy and poor prognosis. The evaluation of response pattern is easy to perform, feasible in clinical practice and, if validated, a promising biomarker for treatment decisions
