Aim. The goal of this study was to semiquantitatively detect presence of cancer stem cells markers CD44 and CD133 in immunohistochemically stained paired samples of colorectal cancer (CRC) and colorectal liver metastases (CLM). Level of staining intensity was compared to clinical and pathological characteristics of tumors with the aim to identify impact of CD44 or CD133 expression on tumor behavior.Patients and Methods. Formalin fixed paraffin embedded samples from 94 patients with colorectal tumor and liver metastases were collected at Sikl’s Department of Pathology. Samples were stained by antibodies against CD44 and CD133. Presence and intensity of staining was assessed semiquantitatively by three trained researchers.Results. Patients with higher level of CD133 staining in CRC had longer disease free interval (Cox-MantelP=0.0244), whereas we found no relation between CD44 expression and overall survival or disease free interval. CD133 expression in CRC and CLM differed based on CRC grading; in case of CD44 we found differences in staining intensity in individual stages of tumor lymph node invasion.Conclusion. Effect of cancer stem cell markers on prognosis of colorectal cancer can vary depending on pathological classification of tumor, and we have shown that CD133, generally considered to be a negative marker, can bear also clinically positive prognostic information in group of patients with colorectal liver metastases.

Purpose Although oncosurgical strategies have demonstrated increased survival in patients with unresectable colorectal liver metastases (CLM), their potential for cure is still questioned. The aim of this study was to evaluate long-term outcome after combining downsizing chemotherapy and rescue surgery and to define prognostic factors of cure. Patients and Methods All patients with initially unresectable CLM who underwent rescue surgery and had a minimum follow-up of 5 years were included. Cure was defined as a disease-free interval ≥ 5 years from last hepatic or extrahepatic resection until last follow-up. Results Mean age of 184 patients who underwent resection (April 1988 through July 2002) was 56.9 years. Patients had a mean number of 5.3 metastases (bilobar in 76%), associated to extrahepatic disease in 27%. Surgery was possible after one (74%) or more (26%) lines of chemotherapy. Five- and 10-year overall survival rates were 33% and 27%, respectively. Of 148 patients with a follow-up ≥ 5 years, 24 patients (16%) were considered cured (mean follow-up, 118.6 months), six (25%) of whom were considered cured after repeat resection of recurrence. Twelve “cured” patients (50%) had a disease-free interval more than 10 years. Cured patients more often had three or fewer metastases less than 30 mm (P = .03) responding to first-line chemotherapy (P = .05). Multivariate analysis identified maximum size of metastases less than 30 mm at diagnosis, number of metastases at hepatectomy three or fewer, and complete pathologic response as independent predictors of cure. Conclusion Cure can be achieved overall in 16% of patients with initially unresectable CLM resected after downsizing chemotherapy. In addition to increased survival, this oncosurgical approach has real potential for disease eradication.

Abstract Introduction In the literature, results after surgical treatment of non-colorectal non-neuroendocrine liver metastases (NCNNLM) are reported that are often inferior to those from colorectal liver metastases. The selection of patients with favorable tumor biology is currently still a matter of discussion. Materials/methods The retrospective data analysis was based on data that were collected for the multicenter study “Role of surgical treatment for non-colorectal liver metastases” in county Thuringia. Results For the study, 637 patients were included from 1995 to 2018. 5 and 10-year survival of R0 resected patients were 33% and 19%, respectively. In the multi-variate analysis of the entire group, sex, timing, disease-free interval, number of metastases, R-classification as well as lymph node status of the primary lesion showed an independent statistical influence on the 5-year survival. In the group of R0 resected patients, disease-free interval, number of metastases and lymph node status of the primary lesion influenced the 5-year survival in the multi-variate analysis. In kidney malignancies, R-classification, timing and number of liver metastases were statistically significant in the multi-variate analysis of the 5-year survival, in mamma carcinomas only the R-classification. Conclusion The Adam score identifies some risk factors which influence prognosis in most but not in all tumor entities. For kidney cancer and breast cancer it can be simplified.

Breast liver metastases are uncommon and have not been well reported. We studied the clinical outcome of 47 patients who developed liver metastases out of 912 breast cancer patients treated between 1982 and 1987, an incidence of 5.2%. The median disease free interval prior to clinical liver metastases was 20.2 months (range 4–192 months). The most frequent clinical presentations were hepatomegaly (70%) and abdominal pain (34%). The diagnosis was confirmed on ultrasound scan in 72.7% patients. Thirty-one patients (70.5%) received specific treatment with both hormone and chemotherapy but only six showed any evidence of objective response, the majority of whom had metastases only in the liver. The median survival of treated patients was 4 months and absence of jaundice, response to treatment and liver metastases only were associated with significantly better survival. In conclusion breast liver metastases usually present as a manifestation of disseminated disease and have an appalling prognosis. When they occur as an initial site the prognosis is better but very few patients overall respond to conventional treatment.

1039 Background: Despite recent treatment improvements, the prognosis of BCLM is still poor. Hepatic resection (HR) has been associated with better outcome in selected patients, but its place in multimodality treatment of BCLM remains controversial. This study aimed to examine the outcome of a large cohort of patients selected for HR of BCLM and to define prognostic factors of survival, in a way to better define the place of surgery. Methods: A standardized questionnaire reviewing the main diagnostic and treatment modalities of primary tumor, liver metastases, response to medical therapies, type of surgical procedures, postoperative outcome, and survival following surgery, was sent to all contributing centers. Results: 460 patients treated with liver resection for BCLM from 1980 to 2000, were collected from 31 hepatobiliary surgery centers. Mean age was 51.8 years. Primary tumor, mainly adenocarcinoma, was treated by resection combined with chemotherapy and/or radiotherapy in most cases. Diagnosis of BCLM was made after an average of 54 months from the treatment of the primary tumor. BCLM were unique in 56% and associated to limited extrahepatic disease in 18.5% of patients. After initial treatment by systemic therapy (70% of patients), HR achieved a R0 resection in 82% of patients and was combined to extrahepatic resection for distant metastases in 9% of patients. Postoperative mortality (= 2 months) was 0.2%. Median survival was 45.4 months after HR, with an overall survival of 41% and 22% at 5 and 10 years, respectively. Disease-free survival rates were 14% and 10%, respectively. Four predictive factors were independently associated to an unfavourable outcome: tumor progression on chemotherapy before surgery (p = 0.0006, RR = 2.9), disease-free interval < 12 months after treatment of the primary tumor (p = 0.0003, RR = 2.1), extrahepatic metastases (p = 0.0002, RR = 1.9) and R2 liver resection (p < 0.0001, RR = 3.0). Conclusions: Inclusion of HR in the multimodality treatment of BCLM is safe and associated with a hope of long term survival (22% at 10 years). Surgery should be discussed on a multidisciplinary basis, particularly when potentially radical, in patients well controlled by chemotherapy with a long disease-free interval, and in the absence of extrahepatic disease. No significant financial relationships to disclose.

PURPOSE More than 50,000 patients in the United States will present each year with liver metastases from colorectal cancers. The current study was performed to determine if liver resection for colorectal metastases is safe and effective and to evaluate predictors of outcome. MATERIALS AND METHODS Data for 456 consecutive resections performed between July 1985 and December 1991 in a tertiary referral center were analyzed. RESULTS The perioperative mortality rate was 2.8%, with a mortality rate of 4.6% for resections that involved a lobectomy or more. The median hospital stay was 12 days and only 9% of patients were admitted to the intensive care unit. The 5-year survival rate is 38%, with a median survival duration of 46 months. By univariate analysis, nodal status of the primary lesion, short disease-free interval before detection of liver metastases, carcinoembryonic antigen (CEA) level greater than 200 ng/mL, multiple liver tumors, extrahepatic disease, large tumors, or positive resection margin was predictive of poorer outcome. Sex, age greater than 70 years, site of primary tumor, or perioperative transfusion was not predictive of outcome. By multivariate analysis, positive margin, size greater than 10 cm, disease-free interval less than 12 months, multiple tumors, and extrahepatic disease were independent predictors of poorer outcome. Short disease-free interval or multiple tumors were nevertheless associated with a 5-year survival rate greater than 24%. CONCLUSION Liver resection for colorectal metastases is safe and effective therapy and currently represents the only potentially curative therapy for metastatic colorectal cancer. The only absolute contraindication to resection is extrahepatic disease. A randomized trial to examine efficacy of surgical resection cannot ethically be performed. Liver resection should be considered standard therapy for all fit patients with colorectal metastases isolated to the liver.
