OBJECTIVE The aim of the study is to assess the prognostic and predictive value of circulating tumor cells (CTCs) and disseminated tumor cells (DTCs) in bone marrow (BM) in patients with colorectal liver metastasis referred to surgery. BACKGROUND A total of 194 patients were included. Treatment of the patients was decided in a multidisciplinary team. METHODS BM aspirates and blood samples were collected at surgery, or in local anesthesia in nonresectable patients. CTCs were disclosed with CellSearch System, DTC with immunocytology. RESULTS Liver resection was completed in 153 patients. Forty-one patients were nonresectable, 22 preoperatively and 19 intraoperatively. The median follow-up was 22 (range 1-61) months. Relapse was diagnosed in 103 of the resected patients. Totally, 67 patients died of cancer. CTCs were detected in 19.6% of the patients. CTC positivity was significantly higher in nonresectable (46%) than in resectable patients (11.7%), P < 0.001. 13.8% of the patients had 2 or more CTCs, 31% of the nonresectable and 9.1% of the resectable patients (P = 0.001). Patients with 2 or more CTCs experienced reduced time to relapse/progression, both analyzing all patients (P = 0.002) and analyzing resectable patients (P < 0.001). Two or more CTCs was a strong predictor of progression and mortality in all subgroups of patients, together with more than 3 liver metastases, R1 resection, and extrahepatic disease. DTCs were detected in 9.9% of the patients, but not associated with clinical outcome in resectable patients. CONCLUSIONS CTCs predict nonresectability and impaired survival. CTC analysis should be considered as a tool for decision-making before liver resection in these patients.

PurposeLaparoscopic distal pancreatectomy is becoming increasingly established at specialized surgical institutions worldwide. The purpose of this study was to compare single-incision laparoscopic distal pancreatectomy (panLESS) with conventional laparoscopic distal pancreatectomy (panLAP) to assess feasibility and 30-day morbidity.MethodsEight consecutive patients who underwent panLESS were matched with patients who underwent panLAP in the same time period. Matching criteria were age, body mass index, and American Society of Anesthesiologists score. Feasibility was based on tumor size, operative time, intraoperative bleeding, resection status, and hospital stay. Thirty-day morbidity was defined by the revised Accordion Classification system and the International Study Group on Pancreatic Fistula definition.ResultsOver a 19-month period, 8 and 16 patients were identified for panLESS and panLAP, respectively. There were no significant differences in tumor size, operative time, intraoperative bleeding, resection status, and hospital stay between the two groups. Surgical complications developed in four panLESS patients and five panLAP patients, and out of which, two patients from each group developed a postoperative pancreatic fistula (grade B).ConclusionsThis study indicates that panLESS is comparable to panLAP in terms of feasibility. More experience is needed to define what role single-incision distal pancreatectomy should have in minimal invasive pancreatic surgery.

Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM) in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months). Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

There is debate as to the correct treatment algorithm sequence for patients with locally advanced rectal cancer with liver metastases. The aim of the study was to assess safety, resectability and survival after a modified ‘liver‐first’ approach.

The aim of this study was to validate clinical risk scores in patients underwent laparoscopic resection of colorectal liver metastases (CLM) with 5 years follow‐up or more, and assess 5‐ and 10‐year actual survival in this group.

Highlights • Hepatocellular carcinoma in ectopic liver tissue is extremely rare.• Multiple successful resections of recurrent ectopic hepatocellular carcinoma.• Postoperative follow-up every 6 month with AFP and abdominal CT imaging.• Early MRI of the liver to exclude intrahepatic disease.
