    Resection of colorectal liver metastases is a treatment standard because patients experience long-term disease-free survival or are even cured after undergoing this procedure. Improved surgical techniques for liver resection in combination with downsizing liver metastases by chemotherapy, interventions to induce liver hypertrophy before resection, and the use of ablative techniques have allowed us to expand the indications for liver surgery and local treatment in situations with limited metastatic colorectal cancer. Resectability and identification of patients who might benefit from liver surgery and local ablative techniques are key factors for the treatment of patients with colorectal cancer. Despite the wide acceptance of liver surgery and ablative techniques, there are many open questions on the management of limited metastatic disease, such as which patients benefit from an aggressive surgical approach, what the indications for ablative and other local techniques are, and what the role of chemotherapy is for patients with resectable or resected disease. Unfortunately, results of randomized trials are only available for a limited number of these questions. PMID:27249722

    The purpose was to evaluate the clinical results of stereotactic radiotherapy in primary liver tumors and hepatic metastases. Five patients with primary liver cancer and 39 patients with 51 hepatic metastases were treated by stereotactic radiotherapy since 1997. Twenty-eight targets were treated in a 'low-dose'-group with 3x10 Gy (n=27) or 4x7 Gy (n=1) prescribed to the PTV-encl. 65%-isodose. In a 'high-dose'-group patients were treated with 3x12 - 12.5 Gy (n=19; same dose prescription) or 1x26 Gy/PTV-enclosing 80%-isodose (n=9). Median follow-up was 15 months (2-48 months) for primary liver cancer and 15 months (2-85 months) for hepatic metastases. While all primary liver cancers were controlled, nine local failures (3-19 months) of 51 metastases were observed resulting in an actuarial local control rate of 92% after 12 months and 66% after 24 months and later. A borderline significant correlation between dose and local control was observed (p=0.077): the actuarial local control rate after 12 and 24?months was 86% and 58% in the low-dose-group versus 100% and 82% in the high-dose-group. In multivariate analysis high versus low-dose was the only significant factor predicting local control (p=0.0089). Overall survival after 1 and 2 years was 72% and 32% for all patients and was impaired due to systemic progression of disease. No severe acute or late toxicity exceeding RTOG/EORTC-score 2 were observed. Stereotactic irradiation of primary liver cancer and hepatic metastases offers a locally effective treatment without significant complications in patients, who are not amenable for surgery. Patient selection is important, because those with low risk for systemic progression are more likely to benefit from this approach.

    To determine the prognostic and predictive value of liver volume in colorectal cancer patients with unresectable liver metastases. Sixteen patients received whole liver radiotherapy (WLRT) between January 1997 and June 2013. A total dose of 21 Gy was delivered in 7 fractions. The median survival time after WLRT was 9 weeks. In univariate analysis, performance status, serum albumin and total bilirubin level, liver volume and extrahepatic metastases were associated with survival. The mean liver volume was significantly different between subgroups with and without pain relief (3,097 and 4,739 mL, respectively; p = 0.002). A larger liver volume is a poor prognostic factor for survival and also a negative predictive factor for response to WLRT. If patients who are referred for WLRT have large liver volume, they should be informed of the poor prognosis and should be closely observed during and after WLRT.

    Each year in the UK, between 12-14,000 people develop liver metastases from colorectal cancer. These metastases will contribute to the death of the patient in about 80% of cases. Treatments aimed at these tumours are best administered when the tumour is small. Current investigative methods allow tumours as small as 0.5 mm to be detected, and should be offered to all colorectal cancer patients at risk of developing liver metastases.

    Full Text Available Development of an optimal algorithm of ray diagnostic examinations in the case of colorectal cancer liver metastases is extremely important. The paper reviews the literature on the diagnosis of colorectal cancer liver metastases. Diagnosis of liver metastases is based on imaging techniques that allow you to assess the condition of the liver, the number and size of lesions and the number of parameters on which the patient is suitable for radical surgery. Described ultrasound (US, computed tomography (CT and magnetic resonance imaging (MRI semiotics of liver metastases, and reflect additional information that can be obtained using beam methods of research, which is of great importance in determining resectability and preoperative planning of surgery. We consider differential diagnosis with benign tumors of the liver. The value and priority of such methods of radiation diagnosis as ultrasound with contrast, CT and MRI contrast agents, is widely debated among experts.

    AIM: Liver metastases from breast cancer (BCLM) are associated with poor prognosis. Cytotoxic chemotherapy can result in regression of tumor lesions and a decrease in symptoms. Available data, in the literature, also suggest a subgroup of patients rraay berefit from surgery, but few talked about transcatheter arterial chemoembolization (TACE).We report the results of TACE and systemic chemotherapy for patients with liver metastases from breast cancer and evaluate the prognostic factors. METHODS: Forty-eight patients with liver metastases, from proved breast primary cancer were treated with TACEor systemic chemotherapy between January 1995 and December 2000. Treatment results were assessed according to WHO criteria, along with analysis of prognostic factors for survival using Cox regression model.RESULTS: The median follow-up was 28 mo (1-72 mo). Response rates were calculated for the TACE group and chemotherapy group, being 35.7% and 7.1%,respectively. The difference was significant. The one-, two- and three-year Survival rates for the TACE group were 63.04%, 30.35%, and 13.01%, and those for the systemic chemotherapy group were 33.88%, 11.29%, and 0%. According to univariate analysis, variables significantly associated with survival were the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight. Other factors such as age, the intervals between the primary to the metastases, the maximal diameter of the liver metastases, the number of liver metastases, extrahepatic metastasis showed no prognostic significances. These factors mentioned above such as the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight were also independent factors in multivariate analysis.CONCLUSION: TACE treatment of liver metastases from breast cancer may prolong survival in certain patients. This approach offers new promise for the curative treatment of the patients

    Liver metastases in colorectal cancer patients decreases the expected 5 year survival rates by a factor close to nine. It is generally accepted that resection of liver metastases should be attempted whenever feasible. This manuscript addresses the optimal therapeutic plan regarding timing of resection of synchronous liver metastases and the use of chemotherapy in combination with resection of synchronous metachronous liver metastases. The aim is to pool all published results in order to attribute a level of evidence to outcomes and identify lacking evidence areas. A systematic search of guidelines, reviews, randomised controlled, observational studies and updating a meta-analysis was performed. Data were extracted and analysed. Data failed to demonstrate an effect of timing of surgery or use of chemotherapy on overall survival. Concomitant resection of liver metastases and the primary tumour may result in lower postoperative morbidity. Systemic peri-operative chemotherapy may improve progression free survival compared to surgery alone. PMID:25666309

  19. Calcifying liver metastases. Computed tomography imaging and incidence of primary colorectal cancer

    International Nuclear Information System (INIS)

    A total of 24 patients with liver metastases of the calcifying type were detected during CT scan imaging for cancer of different primary origin (colorectal, ovarian, mammary, gastric, prostatic melanoma). These calcifying metastases represented 27% of the 89 liver metastases cases detected, and the incidence of a colorectal origin for these calcifying lesions (20% of cases) appears to be highly significant, their number being relatively larger than reported in previous studies. Identification of liver calcifications of possible diagnostic importance requires a two-stage CT scan investigation, before and after bolus. Paraclinical examinations should be directed selectively towards the digestive tract when the primary tumor is unknown

  20. Changes in the renin angiotensin system during the development of colorectal cancer liver metastases

    International Nuclear Information System (INIS)

    Blockade of the renin angiotensin system (RAS) via angiotensin I converting enzyme (ACE) inhibition reduces growth of colorectal cancer (CRC) liver metastases in a mouse model. In this work we defined the expression of the various components of the RAS in both tumor and liver during the progression of this disease. Immunohistochemistry and quantitative RT-PCR was used to examine RAS expression in a mouse CRC liver metastases model. CRC metastases and liver tissue was assessed separately at key stages of CRC liver metastases development in untreated (control) mice and in mice treated with the ACE inhibitor captopril (750 mg/kg/day). Non-tumor induced (sham) mice indicated the effect of tumors on normal liver RAS. The statistical significance of multiple comparisons was determined using one-way analysis of variance followed by Bonferroni adjustment with SAS/STAT software. Reduced volume of CRC liver metastases with captopril treatment was evident. Local RAS of CRC metastases differed from the surrounding liver, with lower angiotensin II type 1 receptor (AT1R) expression but increased ANG-(1-7) receptor (MasR) compared to the liver. The AT1R localised to cancer and stromal infiltrating cells, while other RAS receptors were detected in cancer cells only. Tumor induction led to an initial increase in AT1R and ACE expression while captopril treatment significantly increased ACE expression in the final stages of tumor growth. Conversely, captopril treatment decreased expression of AT1R and angiotensinogen. These results demonstrate significant changes in RAS expression in the tumor-bearing captopril treated liver and in CRC metastases. The data suggests the existence of a tumor-specific RAS that can be independently targeted by RAS blockade

    INTRODUCTION: Colorectal carcinoma accounts for 10% of cancer deaths in the Western World, with the liver being the most common site of distant metastases. Resection of liver metastases is the treatment of choice, with a 5-year survival rate of 35%. However, only 5-10% of patients are suitable for resection at presentation. AIMS: To examine the referral pattern of patients with liver metastases to a specialist hepatic unit for resection. METHODOLOGY: Retrospective review of patient\\'s charts diagnosed with colorectal liver metastases over a 10-year period. RESULTS: One hundred nine (38 women, 71 men) patients with liver metastases were included, mean age 61 years; 79 and 30 patients had synchronous and metachronus metastases, respectively. Ten criteria for referral were identified; the referral rate was 8.25%, with a resection rate of 0.9%. Forty two percent of the patients had palliative chemotherapy; 42% had symptomatic treatment. CONCLUSION: This study highlights the advanced stage of colorectal cancer at presentation; in light of modern evidence-based, centre-oriented therapy of liver metastasis, we conclude that criteria of referral for resection should be based on the availability of treatment modalities.

    Background Morphologic imaging after radiofrequency ablation (RFA) of liver metastases is hampered by an inflammatory response in the ablation margin, making the identification of local tumor progression (LTP) difficult. The aim of this study was to evaluate the efficacy of early 18F-FDG PET/CT scanning to monitor the effectiveness of RFA in colorectal liver metastases.Methods Twelve patients with 20 metastases were treated with RFA for colorectal liver metastases. They underwent PET/CT within 2 weeks before RFA and within 24 hours after RFA (so termed "early PET/CT"). PET/CT was repeated at 1, 3, and 6 months, and then every 6 months after ablation. The standard of reference was based on available clinical and radiological follow-up data.Results Early PET/CT revealed total photopenia in 16 RFA-treated metastases, which were found to be without residual tumor on the final PET/CT scan. Three RFA-treated metastases with focal uptake were identified as local tumor progression, which necessitated further treatment. One RFA-treated metastasis with rim-shaped uptake was regarded as inflammation. The results of the early PET/CT scanning were consistent with the findings of the final follow-up. Conclusions PET/CT performed within 24 hours after RFA can effectively detect whether residual tumor exists for colorectal cancer liver metastases. The results can guide further treatment, and may improve the efficacy of RFA.

  9. Amphiregulin and Epiregulin mRNA expression in primary colorectal cancer and corresponding liver metastases

    International Nuclear Information System (INIS)

    Amphiregulin (AREG) and Epiregulin (EREG), ligands of EGFR, are reported to be predictive biomarkers of colorectal cancer patients treated with Cetuximab, an anti-EGFR antibody. The purpose of this study is to determine the correlation of AREG and EREG expression between primary colorectal cancer and corresponding liver metastases. One hundred twenty colorectal cancer patients with liver metastases (100 with synchronous metastases, 20 with metachronous) were evaluated. No patients had ever received anti-EGFR antibody agents. AREG and EREG mRNA expression from both the primary tumor and liver metastases were measured using real-time RT-PCR. KRAS codon 12, 13 mutation status was analyzed by direct sequencing. Modest, but significant, correlations were observed between primary tumor and corresponding liver metastases in both AREG mRNA expression (Rs = 0.54, p < 0.0001) and EREG mRNA expression (Rs = 0.58, p < 0.0001). AREG and EREG mRNA expression was strongly correlated in both the primary tumor (Rs = 0.81, p < 0.0001) and the liver metastases (Rs = 0.87, p < 0.0001). No significant survival difference was observed between low and high AREG or EREG patients when all 120 patients were analyzed. However, when divided by KRAS status, KRAS wild-type patients with low EREG mRNA levels in the primary site showed significantly better overall survival rates than those with high levels (p = 0.018). In multivariate analysis, low EREG expression was significantly associated with better overall survival (p = 0.006). AREG and EREG expression showed a modest correlation between primary tumor and liver metastases. As EREG mRNA expression was associated with decreased survival, it is appeared to be a useful prognostic marker in KRAS wild-type patients who never received anti-EGFR therapy

    Full Text Available Abstract A 31-year-old man with sigmoid colon cancer with concomitant simultaneous multiple liver metastases had received FOLFIRI (leucovorin, fluorouracil and irinotecan and FOLFOX6 (leucovorin, fluorouracil and oxaliplatin after an ordinary sigmoidectomy. However, his serum carcinoembryonic antigen (CEA level increased rapidly during the fifteen months after the operation while he was on FOLFOX6. Abdominal computed tomography revealed expanding multiple liver tumors. As the third line chemotherapy, a combination therapy of cetuximab with irinotecan was given, which markedly reduced his levels of serum CEA, and the size and number of liver tumors. He underwent lateral segmentectomy of the liver and microwave coagulation of the liver metastases in the remnant liver. Thereafter, a good quality of life with tumor dormancy was obtained for 6 months. However, his serum CEA started to rise again in the absence of liver tumors. Therefore, FOLFOX6 with bevacizumab was chosen as the fourth line chemotherapy, and the serum CEA was reduced with tumor dormancy. A good quality of life was obtained again at 3 years after the first surgery. This report indicates the effectiveness of sandwiched liver surgery with the molecular targeting drugs cetuximab and bevacizumab on multiple liver metastases of colon cancer, and suggests the possibility of a regimen consisting of bevacizumab following cetuximab.

    Metastatic growth by colorectal cancer cells in the liver requires the ability of the cancer cells to interact with the new microenvironment. This interaction results in three histological growth patterns of liver metastases: desmoplastic, pushing, and replacement. In primary colorectal cancer...... several proteases, involved in the degradation of extracellular matrix components, are up-regulated. In liver metastases, their expression is growth pattern dependent. Tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) is a strong prognostic marker in plasma from colorectal cancer patients......, with significant higher levels in patients with metastatic disease. We therefore wanted to determine the expression pattern of TIMP-1 in primary colorectal cancers and their matching liver metastases. TIMP-1 mRNA was primarily seen in α-smooth-muscle actin (α-SMA)-positive cells. In all primary tumors and liver...

    A 69-year-old woman was diagnosed with descending colon cancer with multiple liver metastases, and a left hemicolectomy was performed. The patient was treated with capecitabine/oxaliplatin (CapeOX) plus bevacizumab (Bmab). After 5 courses of chemotherapy, the number and size of liver metastases remarkably reduced, and after the 12th course, because of peripheral neuropathy, a "stop-and-go"fashion of administering oxaliplatin (L-OHP) was initiated. After 14 courses, the liver metastases had disappeared. After the 33rd course of L-OHP treatment, the patient started receiving capecitabine therapy. The patient is recurrence-free 3 years after surgery, 14 months after achieving a complete response (CR). We report a case of long-term CR after surgery for descending colon cancer with multiple liver metastases, followed by a "stop-and-go" method of administering L-OHP or CapeOX plus Bmab therapy.

    Full Text Available Abstract Colorectal cancer (CRC is the third most common cancer in the word. Liver metastasis is the most common site of colorectal metastases. The prognosis of resectable colorectal liver metastases (CRLM was improved in the recent years with the consideration of chemotherapy and surgical resection as part of the multidisciplinary management of the disease; the current 5-year survival rates after resection of liver metastases are 25% to 40%. Resectable synchronous or metachronous liver metastases should be treated with perioperative chemotherapy based on three months of FOLFOX4 (5-fluorouracil [5FU], folinic acid [LV], and oxaliplatin chemotherapy before surgery and three months after surgery. In the case of primary surgery, pseudo-adjuvant chemotherapy for 6 months, based on 5FU/LV, FOLFOX4, XELOX (capecitabine and oxaliplatin or FOLFIRI (5FU/LV and irinotecan, should be indicated. In potentially resectable disease, primary chemotherapy based on more intensive regimens such as FOLFIRINOX (5FU/LV, irinotecan and oxaliplatin should be considered to enhance the chance of cure. The palliative chemotherapy based on FOLFIRI, or FOLFOX4/XELOX with or without targeted therapies, is the mainstay treatment of unresectable disease. This review would provide additional insight into the problem of optimal integration of chemotherapy and surgery in the management of CRLM.

  17. Whole-liver radiotherapy for end-stage colorectal cancer patients with massive liver metastases and advanced hepatic dysfunction

    International Nuclear Information System (INIS)

    To investigate whether whole-liver radiotherapy (RT) is beneficial in end-stage colorectal cancer with massive liver metastases and severe hepatic dysfunction. Between June 2004 and July 2008, 10 colorectal cancer patients, who exhibited a replacement of over three quarters of their normal liver by metastatic tumors and were of Child-Pugh class B or C in liver function with progressive disease after undergoing chemotherapy, underwent whole-liver RT. RT was administered using computed tomography-based three-dimensional planning and the median dose was 21 Gy (range, 21-30) in seven fractions. Improvement in liver function tests, defined as a decrease in the levels within 1 month after RT, symptom palliation, toxicity, and overall survival were analyzed retrospectively. Levels of alkaline phosphatase, total bilirubin, aspartate transaminase, and alanine transaminase improved in 8, 6, 9, and all 10 patients, respectively, and the median reduction rates were 42%, 68%, 50%, and 57%, respectively. Serum carcinoembryonic antigen level decreased after RT in three of four assessable patients. For all patients, pain levels decreased and acute toxicity consisted of nausea/vomiting of grade ≤ 2. Further chemotherapy became possible in four of 10 patients. Mean survival after RT was 80 ± 80 days (range, 20-289); mean survival for four patients who received post-RT chemotherapy was 143 ± 100 days (range, 65-289), versus 38 ± 16 days (range, 20-64) for the six patients who did not receive post-RT chemotherapy (p = 0.127). Although limited by small case number, this study demonstrated a possible role of whole-liver RT in improving hepatic dysfunction and delaying mortality from hepatic failure for end-stage colorectal cancer patients with massive liver metastases. Further studies should be followed to confirm these findings

  19. Percutaneous cryoablation of liver metastases from breast cancer: Initial experience in 17 patients

    International Nuclear Information System (INIS)

    Aim: To assess the feasibility, safety, and effectiveness of percutaneous cryoablation for the treatment of liver metastases from breast cancer. Materials and methods: This study included 39 liver metastases in 17 female breast cancer patients who underwent computed tomography (CT)-guided percutaneous cryoablation. The mean age of the cohort was 55 years (range 30–66 years). The tumour response was evaluated by CT performed before treatment, 1 month after treatment, and every 3 months thereafter. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) was used to assess the patients' quality of life before, 1 week, 1 month, and 3 months after cryoablation. The primary endpoints were technique effectiveness, quality of life, and complications. Results: The technical success rate was 92% with no major complication reported. At the 1-month follow-up, the primary technique effectiveness was 87.1% (34 of 39 tumours). At the 3-months follow-up, local tumour progression was observed in six of 39 lesions (15.4%). The 1-year survival from the time of cryoablation was 70.6%. The quality of life symptoms and functioning scales were preserved in patients alive at 3 months after cryoablation. The global quality of life, mean value of “pain” and “fatigue” between 3 months after cryoablation and prior to treatment showed statistically significant differences, but no clinical significance. Conclusions: Cryoablation is a safe and effective ablative therapy, providing a high rate of local tumour control in breast cancer liver metastases

    A microbeam synchrotron X-ray fluorescence ({mu}SRXRF) technique has been used to determine the localization and the relative concentrations of Zn, Cu, Fe and Ca in primary colorectal cancer and secondary colorectal liver metastases. 24 colon and 23 liver samples were examined, all of which were formalin fixed tissues arranged as microarrays of 1.0 mm diameter and 10 {mu}m thickness. The distribution of these metals was compared with light transmission images of adjacent sections that were H and E stained to reveal the location of the cancer cells. Histological details were provided for each sample which enable concentrations of all elements in different tissue types to be compared. In the case of liver, significant differences have been found for all elements when comparing tumour, normal, necrotic, fibrotic, and blood vessel tissues (Kruskal Wallis Test, P<0.0001). The concentrations of all elements have also been found to be significantly different among tumour, necrotic, fibrotic, and mucin tissues in the colon samples (Kruskal Wallis Test, P<0.0001). The concentrations of all elements have been compared between primary colorectal samples and colorectal liver metastases. Concentration of Zn, Cu, Fe and Ca are higher in all types of liver tissues compared to those in the colon tissues. Comparing liver tumour and colon tumour samples, significant differences have been found for all elements (Mann Whitney, P<0.0001). For necrotic tissues, significant increase has been found for Zn, Ca, Cu and Fe (Mann Whitney, P<0.0001 for Fe and Zn, 0.014 for Ca, and 0.001 for Cu). The liver fibrotic levels of Zn, Ca, Cu and Fe were higher than the fibrotic colon areas (independent T test, P=0.007 for Zn and Mann Whitney test P<0.0001 for Cu, Fe and Ca). For the blood vessel tissue, the analysis revealed that the difference was only significant for Fe (P=0.009) from independent T test.

    Background: Since the liver metastases rather than the colorectal cancer itself is the main determinant of patient’s survival, the ‘Liver-First Approach (LFA)’ with upfront chemotherapy followed by a hepatic resection of colorectal liver metastases (CLM) and finally a colorectal cancer resection was proposed. The aim of this review was to analyse the evidence for LFA in patients with colorectal cancer and synchronous CLM. Methods: A literature search of databases (MEDLINE and EMBASE) to identify published studies of LFA in patients with colorectal cancer and synchronous CLM was undertaken focussing on the peri-operative regimens of LFA and survival outcomes. Results: Three observational studies and one retrospective cohort study were included for review. A total of 121 patients with colorectal cancer and synchronous CLM were selected for LFA. Pre-operative chemotherapy was used in 99% of patients. One hundred and twelve of the initial 121 patients (93%) underwent a hepatic resection of CLM. In total, 60% had a major liver resection and the R0 resection rate was 93%. Post-operative morbidity and mortality after the hepatic resection were 20% and 1%, respectively. Ultimately, 89 of the initial 121 (74%) patients underwent a colorectal cancer resection. Post-operative morbidity and mortality after a colorectal resection were 50% and 6%, respectively. The median overall survival was 40 months (range 19–50) with a recurrence rate of 52%. Conclusions: Current evidence suggests that LFA is safe and feasible in selected patients with colorectal cancer and synchronous CLM. Future studies are required to further define patient selection criteria for LFA and the exact role of LFA in the management of synchronous CLM. PMID:23509899

    Objective: To evaluate the local tumor control and survival data after transarterial chemoembolization with different drug combinations in the palliative treatment of patients with liver metastases of gastric cancer. Materials and methods: The study was retrospectively performed. 56 patients (mean age, 52.4) with unresectable liver metastases of gastric cancer who did not respond to systemic chemotherapy were repeatedly treated with TACE in 4-week intervals. In total, 310 chemoembolization procedures were performed (mean, 5.5 sessions per patient). The local chemotherapy protocol consisted of mitomycin alone (30.4%), mitomycin and gemcitabine (33.9%), or mitomycin, gemcitabine and cisplatin (35.7%). Embolization was performed with lipiodol and starch microspheres. Local tumor response was evaluated by MRI according to RECIST. Survival data from first chemoembolization were calculated according to the Kaplan–Meier method. Results: The local tumor control was: complete response in 1.8% (n = 1), partial response in 1.8% (n = 1), stable disease in 51.8% (n = 29) and progressive disease in 44.6% (n = 25) of patients. The 1-, 2-, and 3-year survival rate from the start of chemoembolization were 58%, 38%, and 23% respectively. The median and mean survival times were 13 and 27.1 months. A Statistically significant difference between patients treated with different chemotherapy protocols was noted (ρ = 0.045) with the best survival time in the mitomycin, gemcitabine and cisplatin group. Conclusion: Transarterial chemoembolization is a minimally invasive therapy option for palliative treatment of liver metastases in patients with gastric cancer.

  6. In vivo imaging of pancreatic tumours and liver metastases using 7 Tesla MRI in a murine orthotopic pancreatic cancer model and a liver metastases model

    International Nuclear Information System (INIS)

    Pancreatic cancer is the fourth leading cause of tumour death in the western world. However, appropriate tumour models are scarce. Here we present a syngeneic murine pancreatic cancer model using 7 Tesla MRI and evaluate its clinical relevance and applicability. 6606PDA murine pancreatic cancer cells were orthotopically injected into the pancreatic head. Liver metastases were induced through splenic injection. Animals were analyzed by MRI three and five weeks following injection. Tumours were detected using T2-weighted high resolution sequences. Tumour volumes were determined by callipers and MRI. Liver metastases were analyzed using gadolinium-EOB-DTPA and T1-weighted 3D-Flash sequences. Tumour blood flow was measured using low molecular gadobutrol and high molecular gadolinium-DTPA. MRI handling and applicability was similar to human systems, resolution as low as 0.1 mm. After 5 weeks tumour volumes differed significantly (p < 0.01) when comparing calliper measurments (n = 5, mean 1065 mm3+/-243 mm3) with MRI (mean 918 mm3+/-193 mm3) with MRI being more precise. Histology (n = 5) confirmed MRI tumour measurements (mean size MRI 38.5 mm2+/-22.8 mm2 versus 32.6 mm2+/-22.6 mm2 (histology), p < 0,0004) with differences due to fixation and processing of specimens. After splenic injection all mice developed liver metastases with a mean of 8 metastases and a mean volume of 173.8 mm3+/-56.7 mm3 after 5 weeks. Lymphnodes were also easily identified. Tumour accumulation of gadobutrol was significantly (p < 0.05) higher than gadolinium-DTPA. All imaging experiments could be done repeatedly to comply with the 3R-principle thus reducing the number of experimental animals. This model permits monitoring of tumour growth and metastasis formation in longitudinal non-invasive high-resolution MR studies including using contrast agents comparable to human pancreatic cancer. This multidisciplinary environment enables radiologists, surgeons and physicians to further improve

    Objective: To evaluate the association between p53 codon 72 polymorphism (R72P) and the risk of colorectal liver metastases. Methods: The p53 R72P genotype was identified by polymerase chain reaction-restriction fi'agment length poly-morphism (PCR-RFLP) method in 78 consecutive colorectal cancer patients with liver metastases and 214 age- and sex-matched cases with nonmetastatic colorectai cancer. Results: The R allele of the p53 R72P polymorphism was more frequently found in metastatic cases than in nonmetastatic cases (P=0.075). Carriers of the 72R allele had a 2.25-fold (95% CI (confidence inter-val)=1.05~4.83) increased risk of liver metastases. On the stratification analysis, 72R-carrying genotype conferred a 3.46-fold (95% CI=1.02~11.72) and a 1.05-fold (95% CI=0.36~3.08) increased risk of liver metastases for p53 overexpression-positive and negative colorectal cancers, respectively. Conclusion: These results demonstrate for the first time that the 72R allele of the p53 polymorphism has an increased risk for liver metastases in colorectal cancers positive for p53 overexpression.

    Objective: Evaluation of the efficacy and tolerability of transarterial chemoembolization with gemcitabine in patients with inoperable liver metastases of breast cancer. Materials and methods: Open-label, prospective non-randomized single-center study design; patients had previous chemotherapy including anthracyclines and/or taxanes in the metastatic setting, adequate bone marrow reserve, sufficient liver/renal function, no centralnervous system metastases, Karnovsky-performance-status >70%, and life expectancy >12 weeks. Forty-three patients were enrolled (median 58 years, range 48–71). A suspension of gemcitabine 1.200 mg/m{sup 2}, 2–10 ml/m{sup 2} of Lipiodol, and 5 ml of a degradable starch microsphere (Embocept) suspension, were administered intra-arterially up to 3 times with a 4-weaks-interval. Dose-limiting toxicit is defined as grade 4 thrombocytopenia, neutropenia, or nonhematologic toxicity > grade 3. Tumor response was evaluated by magnetic resonance (MRI) and computed tomography (CT) imaging. Results: All patients tolerated the treatment well; with no dose limiting toxicities. Imaging follow-up according to the RECIST-criteria (Response Evaluation Criteria in Solid Tumors) revealed a partial response in 3 patients, stable disease in 16 patients and progression in 22 patients. The progression free survival was 3.3 months. A significant correlation exists only with the factor vascularization: strongly vascularized tumors show a significantly lowered response. Patients with complete or partial response and the main fraction of the stable disease group showed in the MRI and angiography only a moderate vascularization. The resulting estimate of the total survival rate amounts to a median of 10.2 months. Conclusion: Transarterial chemoembolization with gemcitabine is well tolerated and provides an alternative treatment method for patients with liver metastases of breast cancer.

  10. Microinvasion of liver metastases from colorectal cancer: predictive factors and application for determining clinical target volume

    International Nuclear Information System (INIS)

    This study evaluates the microscopic characteristics of liver metastases from colorectal cancer (LMCRC) invasion and provides a reference for expansion from gross tumor volume (GTV) to clinical targeting volume (CTV). Data from 129 LMCRC patients treated by surgical resection at our hospital between January 2008 and September 2009 were collected for study. Tissue sections used for pathology and clinical data were reviewed. Patient information used for the study included gender, age, original tumor site, number of tumors, tumor size, levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199), synchronous or metachronous liver metastases, and whether patients received chemotherapy. The distance of liver microinvasion from the tumor boundary was measured microscopically by two senior pathologists. Of 129 patients evaluated, 81 (62.8 %) presented microinvasion distances from the tumor boundary ranging between 1.0 − 7.0 mm. A GTV-to-CTV expansion of 5, 6.7, or 7.0 mm was required to provide a 95, 99, or 100 % probability, respectively, of obtaining clear resection margins by microscopic observation. The extent of invasion was not related to gender, age, synchronous or metachronous liver metastases, tumor size, CA199 level, or chemotherapy. The extent of invasion was related to original tumor site, CEA level, and number of tumors. A scoring system was established based on the latter three positive predictors. Using this system, an invasion distance less than 3 mm was measured in 93.4 % of patients with a score of ≤1 point, but in only 85.7 % of patients with a score of ≤2 points. The extent of tumor invasion in our LMCRC patient cohort correlated with original tumor site, CEA level, and number of tumors. These positive predictors may potentially be used as a scoring system for determining GTV-to-CTV expansion

    The purpose of this study was to evaluate the efficacy of transarterial chemoembolization (TACE) using different drug combinations in the treatment of breast cancer liver metastases in terms of local tumor control and survival rate. A total of 208 patients (mean age 56.4 years, range 29-81) with unresectable hepatic metastases of breast cancer were repeatedly treated with TACE at 4-week intervals. In total, 1,068 chemoembolizations were performed (mean 5.1 sessions/patient, range 3-25). The chemotherapy protocol consisted of mitomycin-C only (8 mg/m{sup 2}; n=76), mitomycin-C with gemcitabine (n=111), and gemcitabine only (1,000 mg/m{sup 2}; n=21). Embolization was performed with lipiodol and starch microspheres. Tumor response was evaluated by MRI according to RECIST criteria. Survival rates were calculated using Kaplan-Meier method. For all protocols, local tumor control was partial response 13% (27/208), stable disease 50.5% (105/208), and progressive disease 36.5% (76/208). The 1-, 2-, and 3-year survival rates after TACE were 69, 40, and 33%. Median and mean survival times from the start of TACE were 18.5 and 30.7 months. Treatment with mitomycin-C only showed median and mean survival times of 13.3 and 24 months, with gemcitabine only they were 11 and 22.3 months, and with a combination of mitomycin-C and gemcitabine 24.8 and 35.5 months. TACE is an optional therapy for treatment of liver metastases in breast cancer patients with better results from the combined chemotherapy protocol. (orig.)

    Background The prognosis for patients with gastric cancer and synchronous liver metastases is very poor.However,a standard therapeutic strategy has not been well established.The clinical benefit and prognostic factors after hepatic surgical treatment for liver metastases from gastric cancer remain controversial.Methods Records of 105 patients who underwent gastrectomy regardless of hepatic surgical treatment for gastric cancer with synchronous liver-only metastases in our center between 1995 and 2010 were retrospectively reviewed.Results The overall survival rate for the 105 patients was 42.1%,17.2%,and 10.6% at 1,2,and 3 years,respectively,with a median survival time of 11 months.Multivariate survival analysis revealed that the extent of lymphadenectomy (D) (P <0.001),lymph node metastases (P <0.001),extent of liver metastases (H) (P=0.008),and lymphovascular invasion (P=-0.002) were significant independent prognostic factors for survival.Among patients who underwent D2 lymphadenectomy,those who underwent hepatic surgical treatment had a significantly improved survival compared with those who underwent gastrectomy alone (median survival,24 vs.12 months; P <0.001).However,hepatic surgical treatment was not a prognostic factor for patients who underwent D1 lymphadenectomy (median survival,8 vs.8 months;P=0.495).For the 35 patients who underwent gastrectomy plus hepatic surgical treatment,D2 lymphadenectomy (P <0.001),lymph node metastases (P=-0.015),and extent of liver metastases (H1 vs.H2 and H3) (P=-0.017) were independent significant prognostic factors for survival.Conclusions D2 lymphadenectomy plus hepatic surgical treatment may provide hope for long-term survival of judiciously selected patients with hepatic metastases from gastric cancer.Patients with a low degree of lymph node metastases and H1 liver metastases would make the most appropriate candidates.However,if D2 dissection cannot be achieved,hepatic surgical treatment is not recommended.

    Full Text Available Objective: Cancer represents the second cause of mortality in the world. Saffron as a medicinal plant is known for its anti-cancer and anti-depressant properties. In this randomized double blind clinical trial, the effects of saffron on response to treatment in patients suffering from liver metastasis were evaluated. Materials and Methods: Thirteen patients suffering from liver metastases who referred to Ghaem and Imam Reza hospital, Mashhad, Iran were included in this study and then divided into two different groups. Both groups received chemotherapy regimen. Patients in group one were treated with saffron capsule (50 mg, twice daily during chemotherapy periods whereas patients in group two received placebo. A sum of the longest diameter were calculated and compared for all lesions in IV contrast CT scan before and after the treatment. Results: from 13 patients included in this study, six patients quit and seven continued until the end. In saffron-treated group, two patients showed partial and complete response (50% whereas in placebo group, no response was seen. Also, two deaths in placebo and one in saffron group occurred. Conclusion: This research suggests that saffron might be useful in patients suffering from liver metastasis. However, further investigations with larger sample size are required.

    Full Text Available The diagnosis and management of CRLM is complex and requires a multidisciplinary team approach for optimal outcomes. Over the past several decades, the 5-year survival following resection of CRLM has increased and the criteria for resection have broadened substantially. Even patients with multiple, bilateral CRLM, previously thought unresectable, may now be candidates for resection. Two-stage hepatectomy, repeat curative-intent hepatectomy, and even selected resection of extrahepatic metastases have further increased the number of patients who may be treated with curative intent. Multiple liver-directed therapies exist to treat unresectable, incurable patients with adequate survival benefit and morbidity rates.

    Selection of the optimal surgical and interventional therapies for advanced colorectal cancer liver metastases (CRLM) requires multidisciplinary discussion of treatment strategies early in the trajectory of the individual patient's care. This paper reports on expert consensus on locoregional and interventional therapies for the treatment of advanced CRLM. Resection remains the reference treatment for patients with bilateral CRLM and synchronous presentation of primary and metastatic cancer. Patients with oligonodular bilateral CRLM may be candidates for one-stage multiple segmentectomies; two-stage resection with or without portal vein embolization may allow complete resection in patients with more advanced disease. After downsizing with preoperative systemic and/or regional therapy, curative-intent hepatectomy requires resection of all initial and currently known sites of disease; debulking procedures are not recommended. Many patients with synchronous primary disease and CRLM can safely undergo simultaneous resection of all disease. Staged resections should be considered for patients in whom the volume of the future liver remnant is anticipated to be marginal or inadequate, who have significant medical comorbid condition(s), or in whom extensive resections are required for the primary cancer and/or CRLM. Priority for liver-first or primary-first resection should depend on primary tumour-related symptoms or concern for the progression of marginally resectable CRLM during treatment of the primary disease. Chemotherapy delivered by hepatic arterial infusion represents a valid option in patients with liver-only disease, although it is best delivered in experienced centres. Ablation strategies are not recommended as first-line treatments for resectable CRLM alone or in combination with resection because of high local failure rates and limitations related to tumour size, multiplicity and intrahepatic location.

    Liver metastases in breast cancer are associated with a poor prognosis. We report long-term survival of a patient with breast cancer and liver metastases. After operation the patient declined further standard therapy. Instead, she was treated with local hyperthermia, Newcastle disease virus and dendritic cell vaccination at the Immunological and Oncological Center Cologne (IOZK), Germany. A continuous high quality of life was reported and the patient survived more than 66 months after initial diagnosis. No recurrence or further metastases developed under treatment. Following treatment, a long-lasting tumor-reactive memory T-cell responsiveness could be documented. This possibly explains the favorable course of disease. Since this combination of therapies is not restricted to a particular tumor type, further exploration is warranted. PMID:26020523

    Advances in surgical and medical treatments have significantly changed the management of colorectal cancer liver metastases (CRCLMs). In particular, new drugs and modern combination chemotherapy regimens, together with the improvement of surgical techniques, allow a potentially curative approach in an increasing number of patients. Nevertheless, there is no strong evidence for an optimal treatment strategy for CRCLMs, mainly because of the extensive heterogeneity in the patients. In fact, although we consider them a population, they represent different clinical and biological subtypes requiring different approaches. Furthermore, results from different studies in this setting may be difficult to interpret, also because the definitions of different patient subgroups are unclear and overlapping. In this review we discuss the results of clinical trials evaluating the role of chemotherapy in the multimodal management of CRCLMs, in either the pre- or postoperative setting. Then we identify three main categories of CRCLM patients, providing clinical recommendations for each. PMID:22964298

    Circulating tumor cells (CTCs) released from a periampullary or pancreatic cancer can be more frequently detected in the portal than the systemic circulation and potentially can be used to identify patients with liver micrometastases. Aims of this study is to determine if CTCs count in portal venous blood of patients with nonmetastatic periampullary or pancreatic adenocarcinoma can be used as a predictor for subsequent liver metastases. CTCs were quantified in portal and peripheral venous blood samples collected simultaneously during pancreaticoduodenectomy in patients with presumed periampullary or pancreatic adenocarcinoma without image-discernible metastasis. Postoperatively patients were monitored for liver metastasis by abdominal magnetic resonance imaging or computed tomography every 3 months for 1 year. Sixty patients with a pathological diagnosis of periampullary or pancreatic adenocarcinoma were included in the study. Multivariate analysis indicated that portal CTC count was a significant predictor for liver metastases within 6 months after surgery. Eleven of 13 patients with a high portal CTCs count (defined as >112 CMx Platform estimated CTCs in 2 mL blood) developed liver metastases within 6 months after surgery. In contrast, only 6 of 47 patients with a low portal CTC count developed liver metastases (P CTCs had 64.7% sensitivity and 95.4% specificity to predict liver metastases within 6 months after surgery. We concluded that a high CTC count in portal venous blood collected during pancreaticoduodenectomy in patients with periampullary or pancreatic adenocarcinoma without metastases detected by currently available imaging tools is a significant predictor for liver metastases within 6 months after surgery.

  20. An international survey on liver metastases radiotherapy

    International Nuclear Information System (INIS)

    Background. An international survey of radiation therapy (RT) of liver metastases was undertaken by the Liver Cancer Workgroup of the Third International Consensus on Metastases Workshop at the 2010 American Society for Radiation Oncology (ASTRO) meeting. Material and methods. Canadian, European, Australian, New Zealand and American centers participated in this online survey. The survey had four objectives: 1) to describe the practice patterns for RT of liver metastases; 2) to report on the use of low-dose RT for symptomatic liver metastases; 3) to report on the use of technology; and 4) to describe the regional differences in the management of liver metastases. Results. A total of 69 individuals treating liver metastases with radiotherapy responded to the survey. Regional response rates ranged from 39% to 50%. The primary professional affiliation of all respondents was evenly distributed amongst ASTRO, CARO, ESTRO and TROG/RANZCR. A 36% increase in the average annual number of referrals over the past five years is reported. The majority of referrals were for radical RT. The most common technologies used were 4D-CT (61%), SBRT (55%), IGRT (50%), and/or IMRT (28%). A uniform treatment approach was not found. The most commonly employed radical regimens were 45 Gy in 3 fractions, 40-50 Gy in 5 fractions, and 45 Gy in 15 fractions. Palliative regimens included 20 Gy in 5 fractions, 30 Gy in 10 fractions, 8 Gy in 1 fraction, and 10 Gy in 2 fractions. Conclusions. This survey suggests radiation oncologists will be seeing more referrals for liver RT. The majority of experience in liver metastases RT is with radical SBRT for focal metastases rather than low-dose palliative RT for symptom control. There is significant variation in technology utilization and dose regimens. Prospective studies or registries may allow for comparison of regimens and identification of parameters to optimize patient selection

    Metastatic growth and invasion by colon cancer cells in the liver requires the ability of the cancer cells to interact with the new tissue environment. Plasmin(ogen) is activated on cell surfaces by urokinase-type PA (uPA), and is regulated by uPAR and plasminogen activator inhibitor-1 (PAI-1......). To compare the expression patterns of uPA, uPAR and PAI-1 in colon cancer with that in their liver metastases, we analysed matched samples from 14 patients. In all 14 primary colon cancers, we found upregulation of uPAR, uPA mRNA and PAI-1 in primarily stromal cells at the invasive front. In 5 of the 14......, whereas 8 of the remaining 9 showed direct contact between the cancer cells and the liver parenchyma. We conclude that there are 2 distinct patterns of expression of uPAR, uPA and PAI-1 in colon cancer liver metastases and that these correlate closely with 2 morphological growth patterns. These findings...

    Complete resection for colorectal metastases is the only treatment that can provide long-term survival and may lead to cure. Recent reports have shown that liver resection following systemic chemotherapy in patients with initially unresectable metastases from colorectal cancer may also result in a good long-term survival, and rescue surgery after chemotherapy has become a strategy of choice. A 29-year-old male and a 35-year-old female with unresectable liver metastases from colorectal cancer underwent complete resection after administration of third-line combination therapy of cetuximab and irinotecan. Although systemic chemotherapy may decrease liver function, which may make liver resection unfeasible, in the two cases reported, liver function did not deteriorate after cetuximab plus irinotecan. The indocyanine green retention rate at 15 minutes, which is useful in deciding the safe limit of hepatectomy, was optimal after the administration of cetuximab plus irinotecan in both patients. Cetuximab plus irinotecan may be beneficial as neoadjuvant chemotherapy for metastatic colorectal cancer, not only because of its oncological efficacy but also for preservation of liver function.

    2012-12-01

    Full Text Available CONTEXT: Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. OBJECTIVES: To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. METHOD: This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. RESULTS: During the period analyzed, 209 procedures were performed on 170 patients. Postope-rative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. CONCLUSION: Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients

  5. Regional differences in prostaglandin E2 metabolism in human colorectal cancer liver metastases

    International Nuclear Information System (INIS)

    Prostaglandin (PG) E2 plays a critical role in colorectal cancer (CRC) progression, including epithelial-mesenchymal transition (EMT). Activity of the rate-limiting enzyme for PGE2 catabolism (15-hydroxyprostaglandin dehydrogenase [15-PGDH]) is dependent on availability of NAD+. We tested the hypothesis that there is intra-tumoral variability in PGE2 content, as well as in levels and activity of 15-PGDH, in human CRC liver metastases (CRCLM). To understand possible underlying mechanisms, we investigated the relationship between hypoxia, 15-PGDH and PGE2 in human CRC cells in vitro. Tissue from the periphery and centre of 20 human CRCLM was analysed for PGE2 levels, 15-PGDH and cyclooxygenase (COX)-2 expression, 15-PGDH activity, and NAD+/NADH levels. EMT of LIM1863 human CRC cells was induced by transforming growth factor (TGF) β. PGE2 levels were significantly higher in the centre of CRCLM compared with peripheral tissue (P = 0.04). There were increased levels of 15-PGDH protein in the centre of CRCLM associated with reduced 15-PGDH activity and low NAD+/NADH levels. There was no significant heterogeneity in COX-2 protein expression. NAD+ availability controlled 15-PGDH activity in human CRC cells in vitro. Hypoxia induced 15-PGDH expression in human CRC cells and promoted EMT, in a similar manner to PGE2. Combined 15-PGDH expression and loss of membranous E-cadherin (EMT biomarker) were present in the centre of human CRCLM in vivo. There is significant intra-tumoral heterogeneity in PGE2 content, 15-PGDH activity and NAD+ availability in human CRCLM. Tumour micro-environment (including hypoxia)-driven differences in PGE2 metabolism should be targeted for novel treatment of advanced CRC

  6. A technique using 99mTc-mebrofenin SPECT for radiotherapy treatment planning for liver cancers or metastases

    International Nuclear Information System (INIS)

    Radiotherapy or stereotactic body radiosurgery (SBRT) requires a sufficient functional liver volume to tolerate the treatment. The current study extended the work of de Graaf et al. (2010) [3] on the use of 99mTc-mebrofenin imaging for presurgery planning to radiotherapy planning for liver cancer or metastases. Patient was immobilized and imaged in an identical position on a single-photon emission computed tomography/computed tomography (SPECT-CT) system and a radiotherapy simulation CT system. 99mTc-mebrofenin SPECT was registered to the planning CT through image registration of noncontrast CT from SPECT-CT system to the radiotherapy planning CT. The voxels with higher uptake of 99mTc-mebrofenin were transferred to the planning CT as an avoidance structure in optimizing a 2-arc RapidArc plan for SBRT delivery. Excellent dose coverage to the target and sparing of the healthy remnant liver volume was achieved. This report illustrated a procedure for the use of 99mTc-mebrofenin SPECT for optimizing radiotherapy for liver cancers and metastases

  7. Benign metastasizing pleomorphic adenoma in liver mimicking synchronic metastatic disease from colorectal cancer: a case report with emphasis on imaging findings

    International Nuclear Information System (INIS)

    Pleomorphic adenoma of the parotid gland with metastases to the liver is a rare etiology of focal liver lesions, and there are no described pathognomonic imaging features. We report a patient who presented with a newly diagnosed rectal cancer and multiple cystic liver lesions suspicious of mucinous synchronous liver metastases. Following chemotherapy no reduction in the number or size of the liver lesions was observed. The patient was re-evaluated and a biopsy of a lesion was performed. The specimen showed a metastasis from a pleomorphic adenoma of the parotid gland for which the patient had been treated 20 years earlier. The case illustrates how a thorough medical history can be crucial when a standard diagnostic imaging workup for colorectal cancer metastases is uncertain, and how a biopsy, though regarded as contraindicated due to the risk of tumor cell dissemination, can be required to secure a correct diagnosis

    2016-04-01

    Until recently, hepatic arterial therapies (HAT) had been used for colorectal liver metastases after failure of first-, second-, and third-line chemotherapies. HAT has gained greater acceptance in patients with liver-dominant colorectal metastases after failure of surgery or systemic chemotherapy. The current data demonstrate that HAT is a safe and effective option for preoperative downsizing, optimizing the time to surgery, limiting non-tumor-bearing liver toxicity, and improving overall survival after surgery in patients with colorectal liver-only metastases. The aim of this review is to present the current data for HAT in liver-only and liver-dominant colorectal liver metastases. PMID:27017870

  10. Improved survival of mice bearing liver metastases of colon cancer cells treated with a combination of radioimmunotherapy and antiangiogenic therapy

    International Nuclear Information System (INIS)

    We attempted to determine whether the combined regimen of radioimmunotherapy (RIT) and antiangiogenic therapy would favorably affect the survival of animals bearing liver metastases of colon cancer cells. Daily antiangiogenic therapy with 2-methoxyestradiol (2-ME), 75 mg/kg, was initiated at 3 days following intrasplenic cell inoculation of LS180 colon cancer cells. RIT with 7 MBq of 131I-A7, an IgG1 anti-colorectal monoclonal antibody, or 131I-HPMS-1, an irrelevant IgG1, was conducted at 7 days. Production of vascular endothelial growth factor (VEGF) by LS180 cells was assessed in vitro. All nontreated mice died by 31 days following cell inoculation (n=5). Monotherapy comprising 2-ME treatment resulted in slightly better survival of mice (n=8) (P131I-A7 RIT displayed a marked therapeutic effect (n=8) (P131I-A7 RIT and antiangiogenic therapy demonstrated a superior therapeutic effect in comparison to monotherapy consisting of either RIT or antiangiogenic therapy (n=10) (P131I-HPMS-1 RIT failed to provide an appreciable benefit (n=5). Treatment with 2-ME decreased VEGF production by LS180 cells in a dose-dependent fashion. In conclusion, a combination regimen comprising RIT and antiangiogenic therapy initiated at the early stage of metastasis would be of great benefit in terms of improvement of the therapeutic efficacy with respect to liver metastases.

  11. Radiofrequency ablation of liver metastases

    International Nuclear Information System (INIS)

    The liver is the second only to lymph nodes as the most common site of metastatic disease irrespective of the primary tumor. Up to 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improvement of the survival time, only approximately 20% of the patients are eligible for surgical intervention. Radiofrequency (RF) ablation represents one of the most important alternatives as well as complementary methods for the therapy of liver metastases. RF ablation can lead in a selected patient group to a palliation or to an increased life expectancy. RF ablation appears either safer (vs. cryotherapy) or easier (vs. laser) or more effective (percutaneous ethanol instillation [PEI]), transarterial chemoembolisation [TACE] in comparison with other minimal invasive procedures. RF ablation can be performed percutaneously, laparoscopically or intraoperatively and may be combined with chemotherapy as well as with surgical resection. Permanent technical improvements of RF systems, a better understanding of the underlying electrophysiological principles and an interdisciplinary approach will lead to a prognosis improvement in patients with liver metastases.

    2012-02-01

    Full Text Available Introduction: Colorectal cancer (CRC is the 3rd leading cause of cancer-related death in the U.S. Many patients with CRC develop hepatic metastases as the sole site of metastases. Historical treatment options were limited to resection or conventional radiation therapy. Stereotactic body radiation therapy (SBRT has emerged as a rational treatment approach. This study reviews our experience with SBRT for patients with liver metastases from CRC.Material and Methods: Fourteen histologically confirmed hepatic CRC metastases in 11 consecutive patients were identified between November, 2004 and June, 2009 at Georgetown University. All patients underwent CT-based treatment planning; a few also had MRI or PET/CT. All patients had fiducial markers placed under CT guidance and were treated using the CyberKnife system. Treatment response and toxicities were examined; survival and local control were evaluated.Results: Most patients were treated to a single hepatic lesion (n=8, with a few treated to 2 lesions (n=3. Median treatment volume was 99.7 cm3, and lesions were treated to a median BED10 of 49.7 Gy (range: 28 – 100.8 Gy. Median follow-up was 21 months; median survival was 16.1 months, with 2-year actuarial survival of 25.7%. One-year local control was 72%. Among patients with post-treatment imaging, 8 had stable disease (80% and 2 had progressive disease (20% at first follow-up. The most common grade 1-2 acute toxicities included nausea and alterations in liver function tests; there was one grade 3 toxicity (elevated bilirubin, and no grade 4-5 toxicities.Discussion: SBRT is safe and feasible for the treatment of limited hepatic metastases from CRC. Our results compare favorably with outcomes from previous studies of SBRT. Further studies are needed to better define patient eligibility, study the role of combined modality treatment, optimize treatment parameters, and characterize quality of life after treatment.

    This paper discusses liver resection for intraabdominal leiomyosarcoma metastases as a therapy for carefully selected patients. Of the 83 hepatectomies performed from 1992 to 1996, five were resections for liver metastases due to intraabdominal leiomyosarcoma, in 3 patients. The surgical indication was single liver metastases, without any evidence of extrahepatic disease. No mortality occurred during surgery and the longest survival was 38 months. We concluded that liver resection for leiomyo...

    Colorectal cancer liver metastases (CLM) treatment is very important given the high incidence of colorectal cancer with liver metastases, which are primarily treated by surgical resection. Transformational therapy such as systemic chemotherapy, hepatic arterial infusion (HAI), portal vein embolization (PVE), ablation therapy, and targeted therapy, should be applied to CLM patients who are unable to undergo immediate surgery to improve patients’ survival and quality of life.

    Electrochemotherapy is a local non-thermal treatment for cancer ablation. Currently, many studies and case report have investigated the differences in effectiveness of electrochemotherapy with respect to tumor type, chemotherapeutic drug, and route of drug administration. ESOPE trial validated standard operating procedures [SOP] for ECT using the Cliniporator device and demonstrated that ECT is a simple, highly efficacious, and cost-effective treatment of cutaneous and subcutaneous nodules from different primary tumors for cutaneous or superficial lesions. This review has the purpose to summarize current knowledge about clinical effectiveness of electrochemotherapy and future prospects regarding its use on pancreatic cancer and liver metastasis not only.

    Purpose. We sought to evaluate our experience using yttrium-90 (90Y) resin microsphere hepatic radioembolization as salvage therapy for liver-dominant metastatic colorectal cancer (mCRC). Methods. A retrospective review of consecutive patients with unresectable mCRC who were treated with 90Y after failing first and second line systemic chemotherapy. Demographics, treatment dose, biochemical and radiographic response, toxicities, and survival were examined. Results. Fifty-one patients underwent 90Y treatments of which 69% were male. All patients had previously undergone extensive chemotherapy, 31% had undergone previous liver-directed therapy and 24% had a prior liver resection. Using RECIST criteria, either stable disease or a partial response was seen in 77% of patients. Overall median survival from the time of first 90Y treatment was 10.2 months (95% CI = 7.5–13.0). The absence of extrahepatic disease at the time of treatment with 90Y was associated with an improved survival, median survival of 17.0 months (95% CI = 6.4–27.6), compared to those with extrahepatic disease at the time of treatment with 90Y, 6.7 months (95% CI = 2.7–10.6 Conclusion: 90Y therapy is a safe locoregional therapy that provides an important therapeutic option to patients who have failed first and second line chemotherapy and have adequate liver function and performance status.

    Here, we report the case of a 43-year-old man who was diagnosed with sigmoid colon cancer with synchronous multiple liver metastases following resection of a primary lesion. Subsequent mFOLFOX+BV therapy elicited a marked response in the liver metastases, which led to the patient undergoing hepatic (S7) radiofrequency ablation (RFA), hepatic resection (lateral segmentectomy and partial [S5] resection), and cholecystectomy. Six months later, transluminal RFA was repeated because liver (S7) metastasis recurred, and 8 courses of XELOX plus BV therapy were administered. As obstructive jaundice due to recurrence of the liver metastases developed after a 6 months hiatus in chemotherapy, we endoscopically inserted a biliary stent. Despite reducing IRIS plus BV therapy, obstructive jaundice developed again, and 3 intrahepatic biliary stents were inserted with percutaneous transhepatic biliary drainage. To date, the patient has been alive for 4 years since the initial resection of the primary lesion after undergoing consecutive systemic chemotherapy with different regimens. Some studies have shown that in cases of obstructive jaundice caused by advanced gastrointestinal cancer, longer survival could be expected by reducing the severity of jaundice, suggesting that resuming chemotherapy as well as improving the severity of jaundice could contribute to better outcomes. The patient in the present case was successfully treated twice with biliary drainage for occlusive jaundice and chemotherapy, suggesting that a combination of multidisciplinary therapy and adequate local therapy such as biliary drainage could be important for the treatment of metastatic liver cancer.

  20. Neoadjuvant TACE before laser induced thermotherapy (LITT) in the treatment of non-colorectal non-breast cancer liver metastases: Feasibility and survival rates

    International Nuclear Information System (INIS)

    Purpose: To evaluate safety, feasibility and overall survival rates for transarterial chemoembolization (TACE) alone or combined with MR-guided laser-induced-thermotherapy (LITT) in liver metastases of non-colorectal and non-breast cancer origin. Methods and materials: Included were patients with unresectable non-colorectal non-breast cancer liver metastases with progression under systemic chemotherapy. Excluded were patients with Karnofsky score ≤70, respiratory, renal and cardiovascular failure, and general TACE contraindications. TACE using Mitomycin alone, Mitomycin–Gemcitabine or Mitomycin–Gemcitabine–Cisplatin was performed to all patients. After TACE 146 metastases were ablated with MR-guided LITT. To be eligible for LITT metastases should be <5 cm in size and ≤5 in number. Tumor response was evaluated using MRI according to RECIST. Survival was evaluated using Kaplan–Meier analysis. Results: A total of 110 patients (mean age 59.2 years) with 371 metastases received TACE (mean 5.4 sessions/patient, n = 110) with 76 (69%) receiving LITT (mean 1.6 session/patient) afterwards. TACE resulted in a mean decrease of mean maximum diameter of 52% ± 26.6 and volume change of −68.5% ± 22.9 in the 25 patients (23%) with partial response. Stable disease (n = 59, 54%). Progressive disease (n = 26, 23%). The RECIST outcome after LITT showed complete response (n = 13, 17%), partial response (n = 1, 1%), stable situation (n = 41, 54%) and progressive disease (n = 21, 28%). The mean time to progression (TTP) was 8.6 months. Median survival of all patients was 21.1 months. Conclusion: TACE with different protocols alone and in combination with LITT is a feasible palliative treatment option resulting in a median survival of 21.1 months for unresectable liver metastases of non-colorectal and non-breast cancer origin

  3. Transcatheter Arterial Chemoembolization (TACE) of Colorectal Cancer Liver Metastases by Irinotecan-Eluting Microspheres in a Salvage Patient Population

    International Nuclear Information System (INIS)

    PurposeThis prospective study evaluated the effectiveness and safety of TACE using irinotecan loaded superabsorbent polymer (SAP) microspheres for treatment of colorectal cancer liver metastases (CCLM) in a salvage setting of patients.MethodsA total of 71 TACE procedures were performed in 29 patients with liver only or liver-dominant CCLM. In all patients, systemic chemotherapy before TACE had failed. Two hundred milligrams of irinotecan were loaded into 50–100 mg of SAP microspheres (HepaSphere™ Microspheres) considering tumor size and vascularization. TACE was performed selectively with respect to tumor distribution. Response was evaluated following RECIST and EASL criteria, respectively. Median follow-up after last TACE was 8 (range 1–54) months. All patients had died at time of analysis.ResultsAll TACE procedures were performed successfully; 35–400 mg (mean 168.3 mg) of irinotecan loaded in 13–100 mg (mean 48.3 mg) SAP microspheres were injected during individual sessions. No major complications occurred. Three, 6, and 12 months after first TACE complete and partial response was present in 72, 32 %, 0 of patients by EASL criteria and stable disease was seen in 86, 48, and 8 % with no complete and no partial response by RECIST criteria. Median overall survival after first TACE was 8 months, and median time to progression was 5 months. Median overall survival was longer in patients with limited (50 %) intrahepatic disease (21 vs. 5 months, p < 0.005).ConclusionsTACE using irinotecan loaded SAP microspheres is safe and effective in terms of tumor necrosis. Survival benefit in a salvage setting seems to be limited in patients with advanced intrahepatic tumor load

  4. Significance of diagnosis of liver metastases from colorectal cancer by angio helical CT and intermittent hepatic arterial infusion chemotherapy after hepatic resection in terms of prognosis

    International Nuclear Information System (INIS)

    Seventy five cases had undergone hepatic resection for liver metastases from colorectal cancer from 1979 to 1994. Computed tomography during hepatic angiography (angio CT) was tried in 27 cases. At first, we compared detection ratios of angio CT for liver metastase to those of ultrasonography, conventional CT, and operative ultrasonography on these 27 cases. Next, the prognosis of seventy five cases was examined. They were divided into three groups; the HX group 29 cases with only hepatic resection; the HX+AP group of 19 cases with intermittent hepatic arterial infusion chemotherapy after hepatic resection; the angio CT group of 27 cases selected for hepatic resection by angio CT, followed by the same infusion chemotherapy as that given to the HX+AP group. Fifty metastases were diagnosed histopathologically in twenty seven cases that underwent hepatic resection after angio CT. Detection ratios for small metastases 1.0 cm or smaller in diameter were 8.3% with ultrasonography, 25% with CT, 75% with angio CT, and 50% with operative ultrasonography. Detection ratios of angio CT were superior to those of ultrasonography and CT. Recurrence rates of the remnant liver were significantly low and survival rates were significantly superior in the angio CT group compared to the other two groups (p<0.02). The prognosis with and without intermittent hepatic arterial infusion chemotherapy after hepatic resection were significantly different (p<0.03). The above data suggest that improvement of detection ratios for liver metastases by angio CT, and probably concomitant intermittent hepatic infusion chemotherapy contribute to decreased remnant liver recurrence and an increased survival rate.

    Metastatic tumors are the most common malignancies of the liver. The frequency distribution of the primary tumor location site closely resembles the frequency distribution of primary cancers in general. Yet, due to the liver's filter function of the portal blood-stream, metastatic tumors of the gastrointestinal tract are overrepresented. Most metastatic tumors show a nodular growth pattern with a demarcation of the tumor by inflammatory or fibrous reactive tissue; a diffuse metastatic tumor spread within the sinusoids is uncommon. Metastatic liver tumors may be the first clinically detectable manifestation of an unknown primary tumor. In these cases, the histological and immunohistochemical pattern of the metastatic tumor cells may give a clue of the location of the corresponding primary tumor. PMID:11220092

  7. Hepatic Arterial Infusion Chemotherapy through a Port-Catheter System as Preoperative Initial Therapy in Patients with Advanced Liver Dysfunction due to Synchronous and Unresectable Liver Metastases from Colorectal Cancer

    International Nuclear Information System (INIS)

    Purpose. We retrospectively evaluated the safety and efficacy of preoperative initial hepatic arterial infusion chemotherapy (HAIC) through a port-catheter system in patients with liver dysfunction due to synchronous and unresectable liver metastases. The aim of HAIC was to improve patients' clinical condition for later surgical removal of primary colorectal cancer. Methods. Port-catheter systems were placed radiologically in 21 patients (mean age 58.6 ± 8.1 years) with liver dysfunction due to synchronous liver metastases from colorectal cancer. Initial HAIC of 1,000 mg/m2 5-fluorouracil was administered weekly as a 5 hr continuous infusion through this system. Surgical removal of the primary lesion was planned after HAIC improved the liver function. Results. Port-catheter system placement was successful in all patients without severe complications. Patients were followed up for a median of 309 days (range 51-998 days). After starting HAIC, no severe adverse events that caused drug loss and treatment postponement or suspension were observed in any of the patients. HAIC was performed a mean of 4.5 ± 3.0 times and the liver function improved in all patients. Curative (n = 18) or palliative (n = 1) surgical removal of the primary lesion was performed. The remaining 2 patients died because extrahepatic metastases developed and their performance status worsened; thus, surgery could not be performed. The median survival times of all patients and the operated patients were 309 and 386 days, respectively. Conclusion. Initial HAIC administration is a safe and efficacious method for improving liver function prior to operative resection of primary colorectal cancer in patients with liver dysfunction due to synchronous and unresectable liver metastases

    Rapid advances in imaging technology have improved the detection, characterization and staging of colorectal liver metastases. Multi-modality imaging approach is usually the more useful in diagnosis colorectal liver metastases. It is well established that hepatic resection improves the long-term prognosis of many patients with liver metastases. However, incomplete resection does not prolong survival, so knowledge of the exact extent of intra-hepatic disease is crucially important in determining patient management and outcome. The diagnosis of liver metastases relies first and totally on imaging to decide which patients may be surgical candidates. This review will discuss the imaging options and their appropriate indications. Imaging and evaluating of colorectal liver metastases (CRLM) have been performed with contrast-enhanced ultrasound, multidetector computed tomography, magnetic resonance imaging (MRI) with extra-cellular contrast media and liver-specific contrast media MRI, and positron emission tomography/computed tomography. This reviewwill concentrate on the imaging approach of CRLM, and also discuss certain characteristics of some liver lesions. We aim to highlight the advantages of each imaging technique, as well as underscoring potential pitfalls and limitations.

  11. Margin Size is an Independent Predictor of Local Tumor Progression After Ablation of Colon Cancer Liver Metastases

    International Nuclear Information System (INIS)

    This study was designed to evaluate the relationship between the minimal margin size and local tumor progression (LTP) following CT-guided radiofrequency ablation (RFA) of colorectal cancer liver metastases (CLM). An institutional review board-approved, HIPPA-compliant review identified 73 patients with 94 previously untreated CLM that underwent RFA between March 2003 and May 2010, resulting in an ablation zone completely covering the tumor 4–8 weeks after RFA dynamic CT. Comparing the pre- with the post-RFA CT, the minimal margin size was categorized to 0, 1–5, 6–10, and 11–15 mm. Follow-up included CT every 2–4 months. Kaplan–Meier methodology and Cox regression analysis were used to evaluate the effect of the minimal margin size, tumor location, size, and proximity to a vessel on LTP. Forty-five of 94 (47.9 %) CLM progressed locally. Median LTP-free survival (LPFS) was 16 months. Two-year LPFS rates for ablated CLM with minimal margin of 0, 1–5 mm, 6–10 mm, 11–15 mm were 26, 46, 74, and 80 % (p < 0.011). Minimal margin (p = 0.002) and tumor size (p = 0.028) were independent risk factors for LTP. The risk for LTP decreased by 46 % for each 5-mm increase in minimal margin size, whereas each additional 5-mm increase in tumor size increased the risk of LTP by 22 %. An ablation zone with a minimal margin uniformly larger than 5 mm 4–8 weeks postablation CT is associated with the best local tumor control.

    We report a case of pseudocirrhosis arising in the setting of regression of liver metastases from pancreatic cancer.A 55-year-old asymptomatic woman presented to ourclinic with newly diagnosed metastatic pancreatic cancer with extensive liver metastases.She underwent systemic chemotherapy with gemcitabine and oxaliplatin (GEHOX).After 8 cycles of therapy,she had a remarkable response to the therapy evidenced by decline of carcinoembryonic antigen (CEA) and CA19 by>50% and nearlycomplete resolution of hepatic metastases in computed tomography (CT) scan.Shortly after,she developed increasing bilateral ankle edema and ascites,associated with dyspnea,progressive weight gain,and declining performance status.Gemcitabine and oxaliplatin were discontinued as other causes of her symptoms such as congestive heart disease or venous thrombosis were ruled out.CT scan 6 mo after the initiation of GEHOX revealed worsening ascites with a stable pancreatic mass.However,it also revealed a Iobular hepatic contour,segmental atrophy,and capsular retraction mimicking the appearance of cirrhosis.She was managed with aggressive diuresis and albumin infusions which eventually resulted in a resolution of the abovementioned symptoms as well as complete resolution of pseudocirrhotic appearance of the liver and ascites in CT scan.This case demonstrates that pancreatic cancer patients can develop pseudocirrhosis.Clinicians and radiologist should be well aware of this entity as early recognition and management can lead to a near complete recovery of liver function and much improved quality of life as illustrated in this case.

    2012-01-01

    Liver metastases synchronously or metachronously occur in approximately 50% of colorectal cancer patients. Multimodality comprehensive treatment is the best therapeutic strategy for these patients. However, the optimal pattern of multimodality therapy is still controversial, and it raises several significant concerns. Liver resection is the most important treatment for colorectal liver metastases. The definition of resectability has shifted to focus on the completion of R0 resection and normal liver function maintenance. The role of neoadjuvant and adjuvant chemotherapy still needs to be clarified. The management of either progression or complete remission during neoadjuvant chemotherapy is challenging. The optimal sequencing of surgery and chemotherapy in synchronous colorectal liver metastases patients is still unclear. Conversional chemotherapy, portal vein embolization, two-stage resection, and tumor ablation are effective approaches to improve resectability for initially unresectable patients. Several technical issues and concerns related to these methods need to be further explored. For patients with definitely unresectable liver disease, the necessity of resecting the primary tumor is still debatable, and evaluating and predicting the efficacy of targeted therapy deserve further investigation. This review discusses different patterns and important concerns of multidisciplinary treatment of colorectal liver metastases.

  14. Preoperative detection of colorectal liver metastases in fatty liver: MDCT or MRI?

    International Nuclear Information System (INIS)

    Objective: To compare the diagnostic value of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the preoperative detection of colorectal liver metastases in diffuse fatty infiltration of the liver, associated with neoadjuvant chemotherapy. Materials and methods: Twenty preoperative tri-phasic MDCT (4-64-row, Siemens) and dynamic contrast-enhanced MRI (1.5 T or 3.0 T, Siemens) examinations of patients with colorectal cancer and liver metastases in diffuse steatosis were retrospectively evaluated. All patients underwent surgical resection for liver metastases (time interval 1-60 days). The amount of fatty infiltration of the liver was determined histopathologically by semi-quantitative percent-wise estimation and ranged from 25 to 75%. Results: Overall, 51 metastases were found by histopathology of the resected liver segments/lobes. The size of the metastases ranged from 0.4 to 13 cm, with 18 (35%) being up to 1 cm in diameter. In the overall rating, MDCT detected 33/51 lesions (65%), and MRI 45/51 (88%). For lesions up to 1 cm, MDCT detected only 2/18 (11%) and MRI 12/18 (66%). One false positive lesion was detected by MDCT. Statistical analysis showed that MRI is markedly superior to MDCT, with a statistically significant difference (p 1 cm. Conclusion: For the detection of colorectal liver metastases after neoadjuvant chemotherapy and consecutive diffuse fatty infiltration of the liver, MRI is superior to MDCT, especially for the detection of small lesions.

    Full Text Available Abstract Uveal melanoma (UM is the most prevalent intraocular malignant tumor in the Western world. The prognosis of survival in the presence of metastatic disease is 2-7 months, depending on the treatment applied. This article presents a case of metastatic UM with successful complex treatment of liver metastases. A 49-year old female, underwent removal of the right eyeball in 1996 due to a histologically confirmed uveal melanoma. After 11 years, CT revealed a mass in the left kidney and multiple metastases in the liver. After left nephrectomy, 6 chemotherapy courses with dacarbazine were performed. The increasing liver metastases were observed. Additional 4 intraarterial (i/a chemotherapy courses were administered using cisplatin, doxorubicin, fluorouracil, and interferon alfa. After few courses increase in CTC Grade 4 liver transaminases was seen. A partial response was observed, and in December 2008 the patient underwent surgery removing all liver metastases by 7 wedge or atypical resections. All margins were tumor-free. 21 months after liver resections and 14 years since diagnosis, the patient is alive without evidence of disease. Successful treatment of metastatic uveal melanoma was due to a timely application of a combination of several treatment methods and good prognostic factors of the patient.

    ) and the average absorbed dose was 92 Gy (range 32-137 Gy). We observed a reduced average absorbed dose as the volume of the lesion increased. Metabolic response was observed for all lesions with a measured average ΔSUVmax of -66% (range -28% to -83%). The observed dose-response relationship suggests that better metabolic response was obtained in lesions receiving the higher dose. Conclusions: three-dimensional voxelized dose-map based on 90Y TOF PET/CT imaging is an effective tool for assessing tumor dose-response relationship. Patients with breast cancer liver metastases showed good short-term metabolic responses with average absorbed doses to lesions ranging between 32 and 137 Gy. A trend showing improved metabolic response in lesions receiving higher doses was observed. (authors)

  18. Radiotherapy for Liver Metastases: A Review of Evidence

    International Nuclear Information System (INIS)

    Over the past decade, there has been an increasing use of radiotherapy (RT) for the treatment of liver metastases. Most often, ablative doses are delivered to focal liver metastases with the goal of local control and ultimately improving survival. In contrast, low-dose whole-liver RT may be used for the palliation of symptomatic diffuse metastases. This review examines the available clinical data for both approaches. The review found that RT is effective both for local ablation of focal liver metastases and for palliation of patients with symptomatic liver metastases. However, there is a lack of a high level of evidence from randomized clinical trials.

    Surgical resection of liver metastases of colorectal cancer greatly improves the clinical outcome of patients with advanced disease. Developments in chemotherapeutic agents and strategies bring hope of a cure to patients with initially unresectable colorectal liver metastases (CLM). Perioperative chemotherapy significantly improves the survival time of patients who receive curative-intent hepatectomy. Even for unresectable CLM, recent studies demonstrated that active preoperative chemotherapy could achieve shrinkage of liver metastasis and thus render some for resection. Furthermore, an increase in tumor resection rate and prolonged survival time among patients with CLM has been observed following the application of monoclonal antibodies in recent years. However, the value of chemotherapy via hepatic arterial infusion is still unclear. More trials should be conducted in patients with CLM in order to improve survival.

    Primary liver cancer is the fifth most common malignancy in men and the eighth in women worldwide. The liver is also the second most common site for metastatic spread of cancer. To assist in the diagnosis of these liver lesions non-invasive advanced imaging techniques are desirable. Magnetic resonance (MR) is commonly used to identify anatomical lesions, but it is a very versatile technique and also can provide specific information on tumor pathophysiology and metabolism,in particular with the application of MR spectroscopy (MRS). This may include data on the type, grade and stage of tumors, and thus assist in further management of the disease. The purpose of this review is to summarize and discuss the available literature on proton, phosphorus and carbon-13-MRS as performed on primary liver tumors and metastases, with human applications as the main perspective. Upcoming MRS approaches with potential applications to liver tumors are also included. Since knowledge of some technical background is indispensable to understand the results, a basic introduction of MRS and some technical issues of MRS as applied to tumors and metastases in the liver are described as well. In vivo MR spectroscopy of tumors in a metabolically active organ such as the liver has been demonstrated to provide important information on tumor metabolism, but it also is challenging as compared to applications on some other tissues, in particular in humans, mostly because of its abdominal location where movement may be a disturbing factor.

    Objective: To compare the diagnostic value of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the preoperative detection of colorectal liver metastases in diffuse fatty infiltration of the liver, associated with neoadjuvant chemotherapy. Materials and methods: Twenty preoperative tri-phasic MDCT (4-64-row, Siemens) and dynamic contrast-enhanced MRI (1.5 T or 3.0 T, Siemens) examinations of patients with colorectal cancer and liver metastases in diffuse steatosis were retrospectively evaluated. All patients underwent surgical resection for liver metastases (time interval 1-60 days). The amount of fatty infiltration of the liver was determined histopathologically by semi-quantitative percent-wise estimation and ranged from 25 to 75%. Results: Overall, 51 metastases were found by histopathology of the resected liver segments/lobes. The size of the metastases ranged from 0.4 to 13 cm, with 18 (35%) being up to 1 cm in diameter. In the overall rating, MDCT detected 33/51 lesions (65%), and MRI 45/51 (88%). For lesions up to 1 cm, MDCT detected only 2/18 (11%) and MRI 12/18 (66%). One false positive lesion was detected by MDCT. Statistical analysis showed that MRI is markedly superior to MDCT, with a statistically significant difference (p < .001), particularly for the detection of small lesions ({<=}1 cm; p < .004). There was no significant difference between the two modalities in the detection of lesions > 1 cm. Conclusion: For the detection of colorectal liver metastases after neoadjuvant chemotherapy and consecutive diffuse fatty infiltration of the liver, MRI is superior to MDCT, especially for the detection of small lesions.

    Eefsen, Rikke Løvendahl

    Colorectal adenocarcinoma (CRC) is the third most frequent cancer type worldwide and the third leading cause of cancer related death. During the course of the disease about 50% of patients are diagnosed with metastatic CRC (mCRC). The 5-year survival for patients who undergo a hepatic resection...... is about 40% and up to 58% in selected groups of patients, while the median overall survival for patients who receive palliative treatment has been reported to be from a few months and up to about 24 months, depending on dissemination of the cancer and response to treatment. The initial neo......-adjuvant treatment is crucial for patients with potential resectable liver metastases, allowing a subsequent hepatic resection if treatment have a downsizing effect on metastases.Antineoplastic agents include chemotherapy (e.g. 5-fluorouracil, oxaliplatin and irinotecan) or a combination of chemotherapy and targeted...

    Pancreatic neuroendocrine tumor(P-NET) is rare and slow-growing. Current classifications predict its progno-sis and postoperative recurrence. Curative resection is ideal, although often difficult, because over 80% of pa-tients have unresectable multiple liver metastases and extrahepatic metastasis. Aggressive surgery for liver metastases is important to improve survival. Aggressive or cytoreductive surgery for liver metastases is indi-cated to reduce hormone levels and improve symptoms and prognosis. Liver transplantation was originally con-ceived as an ideal therapy for unresectable liver metas-tases. Unfortunately, there is no clear consensus on the role and timing of surgery for primary tumor and liver metastases. Surgeons still face questions in deciding the best surgical scenario in patients with P-NET with unresectable liver metastases.

  7. Imaging of dihydrofolate reductase fusion gene expression in xenografts of human liver metastases of colorectal cancer in living rats

    International Nuclear Information System (INIS)

    Radionuclide imaging has been demonstrated to be feasible to monitor transgene expression in vivo. We hypothesized that a potential application of this technique is to non-invasively detect in deep tissue, such as cancer cells metastatic to the liver, a specific molecular response following systemic drug treatment. Utilizing human colon adenocarcinoma cells derived from a patient's liver lesion we first developed a nude rat xenograft model for colorectal cancer metastatic to the liver. Expression of a dihydrofolate reductase-herpes simplex virus 1 thymidine kinase fusion (DHFR-HSV1 TK) transgene in the hepatic tumors was monitored in individual animals using the tracer [124I]2'-fluoro-2'-deoxy-5-iodouracil-β-d-arabinofuranoside (FIAU) and a small animal micro positron emission tomograph (microPET), while groups of rats were imaged using the tracer [131I]FIAU and a clinical gamma camera. Growth of the human metastatic colorectal cancer cells in the rat liver was detected using magnetic resonance imaging and confirmed by surgical inspection. Single as well as multiple lesions of different sizes and sites were observed in the liver of the animals. Next, using a subset of rats bearing hepatic tumors, which were retrovirally bulk transduced to express the DHFR-HSV1 TK transgene, we imaged the fusion protein expression in the hepatic tumor of living rats using the tracer [124I]FIAU and a microPET. The observed deep tissue signals were highly specific for the tumors expressing the DHFR-HSV1 TK fusion protein compared with parental untransduced tumors and other tissues as determined by gamma counting of tissue samples. A subsequent study used the tracer [131I]FIAU and a gamma camera to monitor two groups of transduced hepatic tumor-bearing rats. Prior to imaging, one group was treated with trimetrexate to exploit DHFR-mediated upregulation of the fusion gene product. Imaging in the living animal as well as subsequent gamma counting of tissue samples showed increased

    Manka, David; Spicer, Zachary; Millhorn, David E

    2005-12-15

    The mouse breast cancer cell lines 4T1, 4T07, and 67NR are highly tumorigenic but vary in metastatic potential: 4T1 widely disseminates, resulting in secondary tumors in the lung, liver, bone, and brain; 4T07 spreads to the lung and liver but is unable to establish metastatic nodules; 67NR is unable to metastasize. The Bcl-2/adenovirus E1B 19 kDa interacting protein-3 (Bnip-3) was recently shown to be absent after hypoxia in pancreatic cancer cell lines whereas its overexpression restored hypoxia-induced cell death. We found that Bnip-3 expression increased after 6 hours of hypoxia in all cell lines tested but was highest in the nonmetastatic 67NR cells and lowest in the highly metastatic 4T1 cells. Hypoxia-induced expression of Bnip-3 in the disseminating but nonmetastatic 4T07 cells was intermediate compared with 4T1 and 67NR cells. Cleaved caspase-3, a key downstream effector of cell death, increased after 6 hours of hypoxia in the 67NR and 4T07 cells by 1.9- and 2.5-fold, respectively. Conversely, cleaved caspase-3 decreased by 45% in the highly metastatic 4T1 cells after hypoxia. Small interfering RNA oligonucleotides targeting endogenous Bnip-3 blocked cell death and increased clonigenic survival after hypoxic challenge in vitro and increased primary tumor size and enabled metastasis to the lung, liver, and sternum of mice inoculated with 4T07 cells in vivo. These data inversely correlate the hypoxia-induced expression of the cell death protein Bnip-3 to metastatic potential and suggest that loss of Bnip-3 expression is critical for malignant and metastatic evasion of hypoxia-induced cell death.

    To assess the toxicity and tumor response induced by DCVac/IR dendritic cell (DC) immunotherapy combined with irradiation for refractory colorectal cancer patients with multiple liver metastases. Between May 2004 and November 2006, applicants from a pool of refractory colorectal cancer patients with multiple liver metastases were enrolled. The patients were registered after having signed the informed consent form, which had been approved by the Institutional Review Board from the Dong-A University and Busan National University Hospital. DCs were obtained from peripheral blood of each patient, and then cultured in vitro. A total of 6x10{sup 6} DCs were packed into a vial (DCVac/IR, 0.5 ml) at the convenience of each patient's schedule. On the day before and on the day of each vaccination, each patient received a 4 Gy radiation dose to the target tumor. On the day of vaccination, the indicated dose of autologous DCs was injected into the irradiated tumor using ultrasound-guided needle injection procedures. A total of four vaccinations were scheduled at three 2-week intervals and one 4 week interval at the Dong-A University and Busan National University Hospital. If the tumor status was deemed to be stable or responding to therapy, an additional vaccination dose or two was approved at 4 week intervals beyond the fourth immunization. A tolerance test for DCs was conducted by injecting a range of doses (3x10{sup 6} to 12x10{sup 6} DCs) after the 3rd injection. Moreover, the maximal tolerable dose was applied to additional patients. Treatment safety was evaluated in all patients who had at least one injection. Treatment feasibility was evaluated by the 10th week by assessing the response of patients having at least 4 injections. For systemic toxicities, the evaluation was performed using the National Cancer Institute Common Toxicity Criteria, whereas adverse effects were recorded using common WHO toxicity criteria.

    The role of perioperative chemotherapy in the management of initially resectable colorectal liver metastases (CRLM) is still unclear. The EPOC trial [the European Organization for Research and Treatment of Cancer (EORTC) 40983] is an important study that declares perioperative chemotherapy as the standard of care for patients with resectable CRLM, and the strategy is widely accepted in western countries. Compared with surgery alone, perioperative FOLFOX therapy significantly increased progression-free survival (PFS) in eligible patients or those with resected CRLM. Overall survival (OS) data from the EPOC trial were recently published in The Lancet Oncology, 2013. Here, we discussed the findings and recommendations from the EORTC 40983 trial. PMID:25713806

  16. A randomized controlled trial to investigate the influence of low dose radiotherapy on immune stimulatory effects in liver metastases of colorectal cancer

    International Nuclear Information System (INIS)

    Insufficient migration and activation of tumor specific effector T cells in the tumor is one of the main reasons for inadequate host anti-tumor immune response. External radiation seems to induce inflammation and activate the immune response. This phase I/II clinical trial aims to evaluate whether low dose single fraction radiotherapy can improve T cell associated antitumor immune response in patients with colorectal liver metastases. This is an investigator-initiated, prospective randomised, 4-armed, controlled Phase I/II trial. Patients undergoing elective hepatic resection due to colorectal cancer liver metastasis will be enrolled in the study. Patients will receive 0 Gy, 0.5 Gy, 2 Gy or 5 Gy radiation targeted to their liver metastasis. Radiation will be applied by external beam radiotherapy using a 6 MV linear accelerator (Linac) with intensity modulated radiotherapy (IMRT) technique two days prior to surgical resection. All patients admitted to the Department of General-, Visceral-, and Transplantion Surgery, University of Heidelberg for elective hepatic resection are consecutively screened for eligibility into this trial, and written informed consent is obtained before inclusion. The primary objective is to assess the effect of active local external beam radiation dose on, tumor infiltrating T cells as a surrogate parameter for antitumor activity. Secondary objectives include radiogenic treatment toxicity, postoperative morbidity and mortality, local tumor control and recurrence patterns, survival and quality of life. Furthermore, frequencies of systemic tumor reactive T cells in blood and bone marrow will be correlated with clinical outcome. This is a randomized controlled patient blinded trial to assess the safety and efficiency of low dose radiotherapy on metastasis infiltrating T cells and thus potentially enhance the antitumor immune response.

    Background: Management of patients after locally ablative treatment of liver metastases requires exact information about local control and systemic disease status. To fulfill these requirements, whole-body imaging using positron emission tomography with {sup 18}F-fluorodeoxyglucose (FDG-PET) is a promising alternative to morphologic imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). Purpose: To evaluate FDG-PET for the assessment of local control and systemic disease in patients with clinical suspicion of tumor progression after laser-induced thermotherapy (LITT) of colorectal liver metastases. Material and Methods: In 21 patients with suspicion of progressive disease after LITT, whole-body FDG-PET was performed. The presence of viable tumor within treated lesions, new liver metastases, and extrahepatic disease was evaluated visually and semi quantitatively (maximal standard uptake value [SUVmax], tumor-to-normal ratio [T/N]). The standard of reference was histopathology (n = 25 lesions) and/or clinical follow-up (>12 months) including contrast-enhanced MRI of the liver. Results: Among 54 metastases treated with LITT, 29 had residual tumor. Receiver operating characteristic (ROC) analysis of SUVmax (area under the curve (AUC) 0.990) and T/N (AUC 0.968) showed a significant discrimination level of negative or positive lesion status with an equal accuracy of 94% (51/54). The overall accuracy of visual FDG-PET was 96% (52/54), with one false-negative lesion among six examined within 3 days after LITT, and one false-positive lesion examined 54 days after LITT. In the detection of new intra- and extrahepatic lesions, FDG-PET resulted in correct alteration of treatment strategy in 43% of patients (P = 0.007). Conclusion: FDG-PET is a promising tool for the assessment of local control and whole-body restaging in patients with clinical suspicion of tumor progression after locally ablative treatment of colorectal liver metastases with

    Purpose: before locally ablative treatment of colorectal liver metastases, patients have to be carefully evaluated to decide whether this is the adequate therapy. In this study we determined the value of FDG-PET in comparison to conventional staging procedures. Patients, methods: in 68 consecutive patients referred for laser induced thermotherapy (LITT) of liver metastases from colorectal cancer, pre-therapeutic staging with conventional imaging (thoracic and abdominal CT, liver MRI, chest X-ray) and FDG-PET was performed. The examinations were analysed separately and blinded. Based on the staging information, therapeutic decisions were made by an interdisciplinary review board according to a standardized algorithm. The results were compared between conventional imaging and FDG-PET, and were validated by clinical follow up data and histopathology, respectively. Results: on FDG-PET 210 lesions were interpreted as tumour manifestations. 48 of these were not seen on conventional imaging (true positive, n = 46). In contrast, 24 lesions were visualized by conventional imaging only (true positive, n = 12). Compared to conventional imaging, discrepant findings on FDG-PET led to treatment modifications in 25 patients (37%); these were correct in 20/25 patients. According to the actual treatment course, the inadequate treatment modifications in the remaining 5 patients were avoided by further diagnostic procedures (i.e. biopsies). Conclusions: In the evaluation of patients with known liver metastases from colorectal cancer before LITT, FDG-PET depicts relevant findings subsidiary to conventional imaging and thus is of high value for therapeutic decision making.

    Central nervous system or brain metastases traditionally occur in 10-16% of metastatic breast cancer patients and are associated with a dismal prognosis. The development of brain metastases has been associated with young age, and tumors that are estrogen receptor negative, Her-2+ or of the basal phenotype. Treatment typically includes whole brain irradiation, or either stereotactic radiosurgery or surgery with whole brain radiation, resulting in an approximately 20% one year survival. The blood-brain barrier is a formidable obstacle to the delivery of chemotherapeutics to the brain. Mouse experimental metastasis model systems have been developed for brain metastasis using selected sublines of human MDA-MB-231 breast carcinoma cells. Using micron sized iron particles and MRI imaging, the fate of MDA-MB-231BR cells has been mapped: Approximately 2% of injected cells form larger macroscopic metastases, while 5% of cells remain as dormant cells in the brain. New therapies with permeability for the blood-brain barrier are needed to counteract both types of tumor cells. PMID:17473372

    Metastatic tumors are the most common malignancies of the liver. The frequency distribution of the primary tumor location site closely resembles the frequency distribution of primary cancers in general. Yet, due to the liver's filter function of the portal blood-stream, metastatic tumors of the gastrointestinal tract are overrepresented. Most metastatic tumors show a nodular growth pattern with a demarcation of the tumor by inflammatory or fibrous reactive tissue; a diffuse metastatic tumor spread within the sinusoids is uncommon. Metastatic liver tumors may be the first clinically detectable manifestation of an unknown primary tumor. In these cases, the histological and immunohistochemical pattern of the metastatic tumor cells may give a clue of the location of the corresponding primary tumor. (orig.) [German] Die ueberwiegende Zahl der maligenen Geschwuelste der Leber sind Metastasen. Die Haeufigkeitsverteilung bzgl. ihrer Herkunft aehnelt der allgemeinen Krebsstatistik von Primaertumoren, aufgrund der funktionell anatomischen Besonderheit der Leber als 'Filter' des Portalkreislaufs sind jedoch gastrointestinale Karzinommetastasen ueberpraesentiert. Metastasen wachsen selten diffus, ueberwiegend nodulaer, wobei eine peritumoroese Reaktion zu beobachten ist, die sich in einer kapselartigen oder entzuendlichen Demarkation der Metastase aeussert. Die Art der Demarkation scheint einen Einfluss auf die Prognose des Tumorleidens zu haben. Nicht selten sind Metastasen die erste, klinisch fassbare Manifestation eines unbekannten Primaertumors. Aufgabe des Pathologen ist somit neben der histologischen Sicherung einer Metastase bei bekanntem Primaertumor eine Eingrenzung der Herkunftsmoeglichkeiten bei Metastasen eines Primaertumors unbekannter Lokalisation.

    Colorectal cancer is one of the few malignant tumors in which synchronous or metachronous liver metastases [colorectal liver metastases(CRLMs)] may be treated with surgery. It has been demonstrated that resection of CRLMs improves the long-term prognosis. On the other hand, patients with un-resectable CRLMs may benefit from chemotherapy alone or in addition to liverdirected therapies. The choice of the most appropriate therapeutic management of CRLMs depends mostly on the diagnostic imaging. Nowadays, multiple non-invasive imaging modalities are available and those have a pivotal role in the workup of patients with CRLMs. Although extensive research has been performed with regards to the diagnostic performance of ultrasonography, computed tomography, positron emission tomography and magnetic resonance for the detection of CRLMs, the optimal imaging strategies for staging and follow up are still to be established. This largely due to the progressive technological and pharmacological advances which are constantly improving the accuracy of each imaging modality. This review describes the non-invasive imaging approaches of CRLMs reporting the technical features, the clinical indications, the advantages and the potential limitations of each modality, as well as including some information on the development of new imaging modalities, the role of new contrast media and the feasibility of using parametric image analysis as diagnostic marker of presence of CRLMs.

    Image-guided tumor ablation techniques have significantly broadened the treatment possibilities for primary and secondary hepatic malignancies. A new ablation technique, irreversible electroporation (IRE), was recently added to the treatment armamentarium. As opposed to thermal ablation, cell death with IRE is primarily induced using electrical energy: electrical pulses disrupt the cellular membrane integrity, resulting in cell death while sparing the extracellular matrix of sensitive structures such as the bile ducts, blood vessels, and bowel wall. The preservation of these structures makes IRE attractive for colorectal liver metastases (CRLM) that are unsuitable for resection and thermal ablation owing to their anatomical location. This review discusses different technical and practical issues of IRE for CRLM: the indications, patient preparations, procedural steps, and different "tricks of the trade" used to improve safety and efficacy of IRE. Imaging characteristics and early efficacy results are presented. Much is still unknown about the exact mechanism of cell death and about factors playing a crucial role in the extent of cell death. At this time, IRE for CRLM should only be reserved for small tumors that are truly unsuitable for resection or thermal ablation because of abutment of the portal triad or the venous pedicles.

    In patients with metastatic colorectal cancer, the liver is the most common site of metastatic disease. In patients with liver-dominant disease, consideration needs to be given to locoregional treatments such as hepatic arterial infusion chemotherapy, transarterial chemoembolisation and selective internal radiation therapy because hepatic metastases are a major cause of liver failure especially in chemorefractory disease. In this review we provide insights on the published literature for locoregional treatment of liver metastases in metastatic colorectal cancer.

  8. MR-guided percutaneous cryotherapy of liver metastases

    International Nuclear Information System (INIS)

    The prognosis for patients with liver metastases depends on the therapeutic options regarding the treatment of the primary tumor, co-existing extrahepatic metastases and the extent and treatment possibilities of the hepatic metastases themselves. Numerous curative or palliative oncological therapeutic concepts have been introduced in case of non-resectable liver metastases to prolong survival while maintaining a highest possible quality of life. Cryotherapy, which can be performed percutaneously and under magnetic resonance guidance, is one of these manifold therapeutic modalities, combining the inherent advantages of MRI with minimal invasiveness. Excellent visualization of the frozen liver tissue, precise tumor ablation, as well as an almost painless intervention due to the analgetic effect of the ice are implicating percutaneous cryotherapy as an attractive alternative to other ablation techniques. First clinical results are promising. However, meticulous and extensive long-term evaluation on a broad clinical scale is required. (orig.)

    Full Text Available Abstract Background Despite the fact that metastases are the leading cause of colorectal cancer deaths, little is known about the underlying molecular changes in these advanced disease stages. Few have studied the overall gene expression levels in metastases from colorectal carcinomas, and so far, none has investigated the peritoneal carcinomatoses by use of DNA microarrays. Therefore, the aim of the present study is to investigate and compare the gene expression patterns of primary carcinomas (n = 18, liver metastases (n = 4, and carcinomatoses (n = 4, relative to normal samples from the large bowel. Results Transcriptome profiles of colorectal cancer metastases independent of tumor site, as well as separate profiles associated with primary carcinomas, liver metastases, or peritoneal carcinomatoses, were assessed by use of Bayesian statistics. Gains of chromosome arm 5p are common in peritoneal carcinomatoses and several candidate genes (including PTGER4, SKP2, and ZNF622 mapping to this region were overexpressed in the tumors. Expression signatures stratified on TP53 mutation status were identified across all tumors regardless of stage. Furthermore, the gene expression levels for the in vivo tumors were compared with an in vitro model consisting of cell lines representing all three tumor stages established from one patient. Conclusion By statistical analysis of gene expression data from primary colorectal carcinomas, liver metastases, and carcinomatoses, we are able to identify genetic patterns associated with the different stages of tumorigenesis.

  10. Early Detection of Therapeutic Response to Hepatic Arterial Infusion Chemotherapy of Liver Metastases from Colorectal Cancer Using Diffusion-Weighted MR Imaging

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate whether diffusion-weighted magnetic resonance imaging (DWI) is useful for early detection of the response of hepatic colorectal metastases to hepatic arterial infusion chemotherapy (HAIC) with 5-fluorouracil (5-FU). The subjects were 12 patients with hepatic colorectal metastases. The indwelling catheter for HAIC was placed in the hepatic artery, and 1000 mg/m2 5-FU was given repeatedly once a week. DWI was performed before and 9 days after HAIC. The minimum and mean apparent diffusion coefficient (ADC) values (minADC and meanADC) were measured. The relative change in ADC values (%ADC) and the relative change in tumor size on follow-up CT after 3 months (reduction ratio) were determined. Liver metastases were divided into two groups, responder and nonresponder. The correlation between %ADC and reduction ratio was determined, and %ADC was compared between the two groups. Eleven patients successfully completed HAIC over the 3-month period; 48 metastatic lesions were evaluated. Positive correlations were observed for relative change between %minADC and reduction ratio (r = 0.709) and between %meanADC and reduction ratio (r = 0.536). Both %minADC and %meanADC were significantly greater in the responder group than in the nonresponder group. With the threshold determined as < 3.5%, the receiver-operating curve analysis showed higher sensitivity and specificity values for %minADC (100% and 92.6%, respectively) than for %meanADC (66.7% and 74.1%, respectively). In conclusion, the relative change in minimum ADC values on DWI may be useful for early detection of the response of liver metastases to HAIC with 5-FU.

  13. Importance of liver scintiscanning for the diagnosis of liver metastases

    International Nuclear Information System (INIS)

    Im 1971 and 1972, liver scintiscanning with 99technetium-S-colloid was carried through in 1,570 patients. Their referral diagnoses reflected almost the entire range of medical specialties. 501 patients suspected of carrying liver metastases of the most different kinds of primary tumors, and 122 patients with systemic diseases of supposedly hepatic participation could be selected. From these two collectives it was possible to isolate 218 and 45 patients whose scintigraphic diagnoses could be confirmed. Including the scintigraphically uncertain diagnoses, accuracy in the tumor patients was 87.61%, sensitivity was 90%, and specificity was 86.23%. Without the uncertain diagnoses accuracy was 93.90%, sensitivity 81.39% and specificity 98.34%. Including the scintigraphically uncertain findings, accuracy in the patients with systemic diseases was 77.77%, sensitivity was 50% and specificity was 96.29%. Without the uncertain diagnoses accuracy was 76.31%, sensitivity 25% and specificity 100%. The low sensitivity in systemic diseases, which was due to the rather large number of false-negative diagnoses, was particularly striking as compared to the high specificity. (orig./MG)

    A multicenter randomized study comparing high dose of mitomycin and epirubicin given as hepatic intra-arterial chemotherapy (HIAC) combined with caval chemofiltration (CF) versus low doses of the same drugs in unresectable liver metastases from colorectal cancer showed a significant improvement in the survival rate of the 20 patients treated with high dose compared to the 22 patients treated with low doses with a 1 year survival of 69% vs 39%. The median survival was 17 vs 11 months and the responses were 65% vs 33%. Toxicity was colangitis in 50% of patients considered. The extrahepatic progression was similar in the two groups (7/20 vs 8/22). PMID:15675479

  17. Thermoablation of Liver Metastases: Efficacy of Temporary Celiac Plexus Block

    International Nuclear Information System (INIS)

    Purpose. To determine the efficacy of celiac plexus block during thermoablation of liver metastases. Methods. Fifty-five consecutive patients underwent thermoablation therapy of liver tumors by laser-induced thermotherapy. Twenty-nine patients received a temporary celiac plexus block, 26 patients acted as control group. In both groups fentanyl and midazolam were administered intravenously upon request of the patient. The duration of the intervention, consumption of opiates, and individual pain sensations were documented. Results. No complications resulting from the celiac plexus block were recorded. Celiac plexus block significantly reduced the amount of pain medication used during thermoablation therapy of liver tumors (with block, 2.45 μg fentanyl per kg body weight; without block, 3.58 μg fentanyl per kg body weight, p < 0.05; midazolam consumption was not reduced) in patients with metastases ≤5 mm from the liver capsule. For metastases farther away from the capsule no significant differences in opiate consumption were seen. Celiac plexus block reduced the time for thermoablation significantly (178 min versus 147 min, p < 0.05) no matter how far the metastases were from the liver capsule. Average time needed to set the block was 12 min (range 9-15 min); additional costs for the block were marginal. As expected (as pain medications were given according to individual patients' needs) pain indices did not differ significantly between the two groups. Conclusion. In patients with liver metastases ≤5 mm from the liver capsule, celiac plexus block reduces the amount of opiates necessary, simplifying patient monitoring. In addition celiac plexus block reduces intervention time, with positive effects on overall workflow for all patients

    The liver is, second only to lymph nodes, the most common site for metastatic disease irrespective of the primary tumour. More than 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improved survival in patients with colorectal metastases, only approximately 20% of patients are eligible for surgery. Thermal ablation and especially radiofrequency ablation emerge as an important additional therapy modality for the treatment of liver metastases. RF ablation shows a benefit in life expectancy and may lead in a selected patient group to cure. Percutaneous RF ablation appears safer (versus cryotherapy), easier (versus laser), and more effective (versus ethanol instillation and transarterial chemoembolisation) compared with other minimally invasive procedures. RF ablation can be performed by a percutaneous, laparoscopical or laparotomic approach, and may be potentially combined with chemotherapy and surgery. At present ideal candidates have tumours with a maximum diameter less than 3.5 cm. An untreatable primary tumour or a systemic disease represents contraindications for performing local therapies. Permanent technical improvements of thermal ablation devices and a better integration of thermal ablation in the overall patient care may lead to prognosis improvement in patients with liver metastases.

    International Nuclear Information System (INIS)

    To prospectively evaluate the efficacy and safety of selective internal radiation (SIR) spheres in patients with inoperable liver metastases from colorectal cancer who have failed 5FU based chemotherapy. Patients were prospectively enrolled at three Australian centres. All patients had previously received 5-FU based chemotherapy for metastatic colorectal cancer. Patients were ECOG 0–2 and had liver dominant or liver only disease. Concurrent 5-FU was given at investigator discretion. Thirty patients were treated between January 2002 and March 2004. As of July 2004 the median follow-up is 18.3 months. Median patient age was 61.7 years (range 36 – 77). Twenty-nine patients are evaluable for toxicity and response. There were 10 partial responses (33%), with the median duration of response being 8.3 months (range 2–18) and median time to progression of 5.3 mths. Response rates were lower (21%) and progression free survival shorter (3.9 mths) in patients that had received all standard chemotherapy options (n = 14). No responses were seen in patients with a poor performance status (n = 3) or extrahepatic disease (n = 6). Overall treatment related toxicity was acceptable, however significant late toxicity included 4 cases of gastric ulceration. In patients with metastatic colorectal cancer that have previously received treatment with 5-FU based chemotherapy, treatment with SIR-spheres has demonstrated encouraging activity. Further studies are required to better define the subsets of patients most likely to respond

    This study evaluated the predictive role of 1D, 2D and 3D quantitative, enhancement-based MRI regarding overall survival (OS) in patients with colorectal liver metastases (CLM) following intra-arterial therapies (IAT). This retrospective analysis included 29 patients who underwent transarterial chemoembolization (TACE) or radioembolization and received MRI within 6 weeks after therapy. Tumour response was assessed using 1D and 2D criteria (such as European Association for the Study of the Liver guidelines [EASL] and modified Response Evaluation Criteria in Solid Tumors [mRECIST]). In addition, a segmentation-based 3D quantification of overall (volumetric [v] RECIST) and enhancing lesion volume (quantitative [q] EASL) was performed on portal venous phase MRI. Accordingly, patients were classified as responders (R) and non-responders (NR). Survival was evaluated using Kaplan-Meier analysis and compared using Cox proportional hazard ratios (HR). Only enhancement-based criteria identified patients as responders. EASL and mRECIST did not predict patient survival (P = 0.27 and P = 0.44, respectively). Using uni- and multivariate analysis, qEASL was identified as the sole predictor of patient survival (9.9 months for R, 6.9 months for NR; P = 0.038; HR 0.4). The ability of qEASL to predict survival early after IAT provides evidence for potential advantages of 3D quantitative tumour analysis. (orig.)

    To determine the efficacy of radiofrequency (RF) ablation in neuroendocrine tumor (NET) liver metastases. A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eight studies were included (N = 301). Twenty-six percent of RF ablation procedures were percutaneous (n = 156), with the remainder conducted at surgery. Forty-eight percent of patients had a concomitant liver resection. Fifty-four percent of patients presented with symptoms, with 92% reporting symptom improvement following RF ablation (alone or in combination with surgery). The median duration of symptom improvement was 14-27 months. However, recurrence was common (63%-87%). RF ablation can provide symptomatic relief in NET liver metastases alone or in combination with surgery. PMID:25840836

  6. Transarterial chemoembolization of liver metastases in patients with uveal melanoma

    International Nuclear Information System (INIS)

    Summary: Metastases from uveal melanoma are often confined to the liver. Palliative hepatic chemoembolization has been considered to be a reasonable treatment approach. We enrolled 14 patients with hepatic metastases from uveal melanoma into a pilot trial of transarterial chemoembolization (TACE). All patients received additional systemic immuno-chemotherapy or best supportive care. In 31 procedures 100 mg/m2 of cisplatine was continuously infused by means of a power injector preceding embolization by manual injection of polyvinyl alcohol particles. In three procedures cisplatine was replaced by 200 mg/m2 carboplatine because of increased serum creatinine levels. Tumor response was evaluated using RECIST criteria. Fourteen patients received 34 TACE's (mean: 2.4 treatments). Eight patients (57%) achieved partial response (PR), four patients (29%) had stable disease and two patients (14%) tumor progression. Median time to progression was 8.5 months (5-35 months). Median survival after first TACE was 14.5 months in responders compared to 10 months in non-responders (p = 0.18, not significant) and 11.5 months (3-69 months) in all patients. In seven patients with metastases occupying less than 25% of liver volume median survival was 17 months compared to 11 months in seven patients with tumor involvement of more than 25% (p = 0.02) with partial response rate of 86% and 29%, respectively. TACE of liver metastases from uveal melanoma is well tolerated and may prolong survival in patients with limited tumor extension.

In seven patients with metastases occupying less than 25% of liver volume median survival was 17 months compared to 11 months in seven patients with tumor involvement of more than 25% (p = 0.02) with partial response rate of 86% and 29%, respectively. TACE of liver metastases from uveal melanoma is well tolerated and may prolong survival in patients with limited tumor extension.

    Assessing the therapeutic benefit of surgical navigation systems is a challenging problem in image-guided surgery. The exact clinical indications for patients that may benefit from these systems is not always clear, particularly for abdominal surgery where image-guidance systems have failed to take hold in the same way as orthopedic and neurosurgical applications. We report interim analysis of a prospective clinical trial for localizing small colorectal liver metastases using the Explorer system (Path Finder Technologies, Nashville, TN). Colorectal liver metastases are small lesions that can be difficult to identify with conventional intraoperative ultrasound due to echogeneity changes in the liver as a result of chemotherapy and other preoperative treatments. Interim analysis with eighteen patients shows that 9 of 15 (60%) of these occult lesions could be detected with image guidance. Image guidance changed intraoperative management in 3 (17%) cases. These results suggest that image guidance is a promising tool for localization of small occult liver metastases and that the indications for image-guided surgery are expanding.

    Breast cancer is the most prevalent cancer among females worldwide leading to approximately 350,000 deaths each year. It has long been known that cancers preferentially metastasize to particular organs, and bone metastases occur in ~70% of patients with advanced breast cancer. Breast cancer bone metastases are predominantly osteolytic and accompanied by increased fracture risk, pain, nerve compression and hypercalcemia, causing severe morbidity. In the bone matrix, transforming growth factor-...

    Full Text Available Cancer metastasis is the major cause of cancer morbidity and mortality, and accounts for about 90% of cancer deaths. Although cancer survival rate has been significantly improved over the years, the improvement is primarily due to early diagnosis and cancer growth inhibition. Limited progress has been made in the treatment of cancer metastasis due to various factors. Current treatments for cancer metastasis are mainly chemotherapy and radiotherapy, though the new generation anti-cancer drugs (predominantly neutralizing antibodies for growth factors and small molecule kinase inhibitors do have the effects on cancer metastasis in addition to their effects on cancer growth. Cancer metastasis begins with detachment of metastatic cells from the primary tumor, travel of the cells to different sites through blood/lymphatic vessels, settlement and growth of the cells at a distal site. During the process, metastatic cells go through detachment, migration, invasion and adhesion. These four essential, metastatic steps are inter-related and affected by multi-biochemical events and parameters. Additionally, it is known that tumor microenvironment (such as extracellular matrix structure, growth factors, chemokines, matrix metalloproteinases plays a significant role in cancer metastasis. The biochemical events and parameters involved in the metastatic process and tumor microenvironment have been targeted or can be potential targets for metastasis prevention and inhibition. This review provides an overview of these metastasis essential steps, related biochemical factors, and targets for intervention.

  14. Predicting the presence of extracranial metastases in patients with brain metastases upon first diagnosis of cancer

    International Nuclear Information System (INIS)

    This study aimed to determine factors allowing the prediction of extracranial metastases in patients presenting with brain metastases at the first diagnosis of cancer. Data from 659 patients with brain metastases upon first diagnosis of cancer were retrospectively analyzed. The parameters age, gender, Karnofsky performance score (KPS), primary tumor type and number of brain metastases were compared between 359 patients with extracranial metastases and 300 patients without extracranial metastases. Additional analyses were performed for patients with the most unfavorable and those with the most favorable characteristics. The comparison of patients with versus without extracranial metastases revealed significant differences between the groups in terms of KPS (p < 0.001) and number of brain metastases (p < 0.001). Of the study patients, 113 had both most unfavorable characteristics, i.e. KPS ≤ 50 and ≥ 4 brain metastases. The sensitivity for identifying patients with extracranial metastases was 82 %; specificity was 51 %. A total of 50 patients had KPS ≥ 90 and only one brain metastasis. The sensitivity for identifying patients without extracranial metastases was 86 %; specificity was 58 %. The combination of KPS and the number of brain metastases can help to predict the presence or absence of extracranial metastases. (orig.)

    Full Text Available The prime role of hepatic resection in the management of colorectal cancer metastatic to the liver is firmly established. At least a third of patients who undergo liver resection for colorectal metastases can expect to survive five years. Since 1999, 106 hepatic metastases were resected in 42 patients (synchr. 8, metachr. 34, pts. We performed 12 monosegmentectomies (S2-S8, 4 bisegmentectomies (S4b, S5 and S5, S6, 6 sectorectomies (right posterior, left paramedian, left lateral, 3 polysegmentectomies (S4b, S5 S6, 8 billateral sectionectomies (S2, S3 and S6,S7 and in 9 cases multiple segmentectomies. In 4 cases initially unresectable colorectal metastases were downstaged by transcatheter HAI regional chemotherapy (Implantofix and after that successfully resected. We favour vascular inflow occlusion through selective division of appropriate portal pedicle at the porta hepatis or by transparenchymal approach. Median blood loss was330±160 ml. The complication rate ammounted to 9.52% (bile fistula, abscess collection. No method related lethality occurred. During the follow-up period we registered tumor recurrence rate of 19.1% (8 pts, of which two patients were subjected to liver re-resection. Overall 3-year survival rate (Kaplan-Meier is 38.9%. Multivariate analysis shows a significant correlation between 3-year survival and solitary (p-0.031 and unilobar metastases (p-0.014.

  16. Evaluation of immunological escape mechanisms in a mouse model of colorectal liver metastases

    International Nuclear Information System (INIS)

    The local and systemic activation and regulation of the immune system by malignant cells during carcinogenesis is highly complex with involvement of the innate and acquired immune system. Despite the fact that malignant cells do have antigenic properties their immunogenic effects are minor suggesting tumor induced mechanisms to circumvent cancer immunosurveillance. The aim of this study is the analysis of tumor immune escape mechanisms in a colorectal liver metastases mouse model at different points in time during tumor growth. CT26.WT murine colon carcinoma cells were injected intraportally in Balb/c mice after median laparotomy using a standardized injection technique. Metastatic tumor growth in the liver was examined by standard histological procedures at defined points in time during metastatic growth. Liver tissue with metastases was additionally analyzed for cytokines, T cell markers and Fas/Fas-L expression using immunohistochemistry, immunofluorescence and RT-PCR. Comparisons were performed by analysis of variance or paired and unpaired t test when appropriate. Intraportal injection of colon carcinoma cells resulted in a gradual and time dependent metastatic growth. T cells of regulatory phenotype (CD4+CD25+Foxp3+) which might play a role in protumoral immune response were found to infiltrate peritumoral tissue increasingly during carcinogenesis. Expression of cytokines IL-10, TGF-β and TNF-α were increased during tumor growth whereas IFN-γ showed a decrease of the expression from day 10 on following an initial increase. Moreover, liver metastases of murine colon carcinoma show an up-regulation of FAS-L on tumor cell surface with a decreased expression of FAS from day 10 on. CD8+ T cells express FAS and show an increased rate of apoptosis at perimetastatic location. This study describes cellular and macromolecular changes contributing to immunological escape mechanisms during metastatic growth in a colorectal liver metastases mouse model simulating the

  17. Comparison of MRI of liver cancer (preoperative and resected liver specimen) and pathological feature

    International Nuclear Information System (INIS)

    Twenty-one nodules of hepatocellular carcinoma (HCC) and eighteen nodules of liver metastasis, which were confirmed pathologically, were investigated by MRI before operation and MRI of resected liver specimen. Pre-operative MRI pointed out all HCCs and seventeen metastases. STIR method was most useful for detection of HCCs. T2WI and STIR method were most useful for detection of liver metastases. Pre-operative MRI also revealed 93% of capsule formation, 29% of septal formation, 75% of fatty metamorphosis of HCC and 75% of necrosis of liver metastasis, and post-operative MRI of resected specimens revealed 100% of capsule formation, 71% of septal formation, 75% of fatty metamorphosis of HCC and 88% of necrosis of liver metastasis. T1WI showed a high intensity halo surrounding metastasis. This characteristic peripheral halo was seen in 22% of metastases. These findings corresponded to pathological feature of liver cancer. MRI was thought to be useful diagnostic modality of liver cancer. (author)

    Purpose: Accurate segmentation and quantification of liver metastases on CT images are critical to surgery/radiation treatment planning and therapy response assessment. To date, there are no reliable methods to perform such segmentation automatically. In this work, the authors present a method for semiautomatic delineation of liver metastases on contrast-enhanced volumetric CT images. Methods: The first step is to manually place a seed region-of-interest (ROI) in the lesion on an image. This ROI will (1) serve as an internal marker and (2) assist in automatically identifying an external marker. With these two markers, lesion contour on the image can be accurately delineated using traditional watershed transformation. Density information will then be extracted from the segmented 2D lesion and help determine the 3D connected object that is a candidate of the lesion volume. The authors have developed a robust strategy to automatically determine internal and external markers for marker-controlled watershed segmentation. By manually placing a seed region-of-interest in the lesion to be delineated on a reference image, the method can automatically determine dual threshold values to approximately separate the lesion from its surrounding structures and refine the thresholds from the segmented lesion for the accurate segmentation of the lesion volume. This method was applied to 69 liver metastases (1.1–10.3 cm in diameter) from a total of 15 patients. An independent radiologist manually delineated all lesions and the resultant lesion volumes served as the “gold standard” for validation of the method’s accuracy. Results: The algorithm received a median overlap, overestimation ratio, and underestimation ratio of 82.3%, 6.0%, and 11.5%, respectively, and a median average boundary distance of 1.2 mm. Conclusions: Preliminary results have shown that volumes of liver metastases on contrast-enhanced CT images can be accurately estimated by a semiautomatic segmentation

  2. Contrast-Enhanced FDG-PET/CT vs. SPIO-Enhanced MRI vs. FDG-PET vs. CT in Patients with Liver Metastases from Colorectal Cancer: A Prospective Study with Intraoperative Confirmation

    International Nuclear Information System (INIS)

    Background: The choice of imaging before liver surgery is debated regarding the use of magnetic resonance (MR) imaging, computed tomography (CT), and positron emission tomography (PET). No studies have compared contrast-enhanced PET/CT with superparamagnetic iron oxide (SPIO)-enhanced MR imaging. Purpose: To compare PET/CT with superparamagnetic iron oxide (SPIO)-enhanced MR imaging, PET, and CT in the detection of liver metastases (LM) and extrahepatic tumor from colorectal cancer (CRC). Material and Methods: Thirty-five patients with suspected LM underwent PET/CT with a contrast-enhanced CT protocol and SPIO-enhanced MR imaging. Readers independently analyzed images from MR imaging, PET/CT, and the CT part and PET part of the PET/CT study. Imaging findings were compared with surgical and histological findings. Results: Lesion-by-lesion sensitivity and accuracy for liver lesions was 54% and 77% for PET alone, 66% and 83% for PET/CT, 82% and 82% for SPIO-enhanced MR imaging, and 89% and 77% for CT alone, respectively. CT and SPIO-enhanced MR imaging were less specific but significantly more sensitive than PET (P<0.0001). For extrahepatic tumor, sensitivity and specificity was 83% and 96% for PET/CT and 58% and 87% for CT, respectively. Conclusion: CT and SPIO-enhanced MR imaging are more sensitive but less specific than PET in the detection of LM. PET/CT can detect more patients with extrahepatic tumor than CT alone

    . Moreover, a signature was developed based on our unsupervised clustering of breast tumors and this was predictive for disease-specific survival in three independent studies. Next, the metastases from ovarian, breast, lung and vulva cluster with their tissue of origin while metastases from colon showed a bimodal distribution. A significant part clusters with tissue of origin while the remaining tumors cluster with the tissue of destination. Conclusion Our molecular taxonomy of epithelial human cancer indicates surprising correlations over tissues. This may have a significant impact on the classification of many cancer sites and may guide pathologists, both in research and daily practice. Moreover, these results based on unsupervised analysis yielded a signature predictive of clinical outcome in breast cancer. Additionally, we hypothesize that metastases from gastrointestinal origin either remember their tissue of origin or adapt to the tissue of destination. More specifically, colon metastases in the liver show strong evidence for such a bimodal tissue specific profile.

    Colorectal cancer (CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent (25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twenty-thirty per cent (20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to resectable to achieve cure. Since those results were published, a lot of regimens have been studied for resectability potential. Better results could be obtained by the combination of chemotherapy with targeted drugs, such as anti-VEGF and anti-EGFR monoclonal antibodies. However an accurate selection for patients to treat with these regimens and to operate for liver metastases is mandatory to reduce the risk of complications. A multidisciplinary team approach represents the best way for a proper patient management. The team needs to include surgeons, oncologists, diagnostic and interventional radiologists with expertise in hepatobiliary disease, molecular pathologists, and clinical nurse specialists. This review summarizes the most important findings on surgery and systemic treatment of CRC-related liver metastases. PMID:27621569

    AIM: To evaluate the influence of preoperative FOLFOX chemotherapy on CCL20/CCR6 expression in liver metastases of stage Ⅳ colorectal cancer (CRC) patients. METHODS: Using Real Time-PCR, enzyme-linked immunosorbent assay, Western Blots and immunohistochemistry, we have analyzed the expression of CCL20, CCR6 and proliferation marker Ki-67 in colorectal liver metastasis (CRLM) specimens from stage Ⅳ CRC patients who received preoperative FOLFOX chemotherapy (n = 53) and in patients who did not receive FOLFOX chemotherapy prior to liver surgery (n = 29). RESULTS: Of the 53 patients who received FOLFOX, time to liver surgery was ≤ 1 mo in 14 patients, ≤ 1 year in 22 patients and > 1 year in 17 patients, respectively. In addition, we investigated the proliferation rate of CRC cells in liver metastases in the different patient groups. Both CCL20 and CCR6 mRNA and protein expression levels were significantly increased in patients who received preoperative FOLFOX chemotherapy ≤ 12 mo before liver surgery (P < 0.001) in comparison to patients who did not undergo FOLFOX treatment. Further, proliferation of CRLM cells as measured by Ki-67 was increased in patients who underwent FOLFOX treatment. CCL20 and CCR6 expression levels were significantly increased in CRLM patients who had undergone preoperative FOLFOX chemotherapy. CONCLUSION: This chemokine/receptor up-regulation could lead to increased proliferation/migration through an autocrine mechanism which might be used by surviving metastatic cells to escape cell death caused by FOLFOX.

  8. The contribution of scintigraphy in the search of liver metastases

    International Nuclear Information System (INIS)

    An outline of some general scintigraphic principles is followed by a non-isotopic study of liver metastases in order to compare the different methods. Liver scintigraphy is then examined from the viewpoint of both the method itself and the results to be expected. This study covered 62 observations of confirmed metastases and 36 for which a metastase was eliminated, i.e. 98 records altogether. The technique involved the use of technetium with a large (5-inch) scintillating crystal and a beehive collimator. No mishap occurred as a result of this examination. Scintigraphy offers a very useful means of exploration because false negatives are rare (4 doubtful cases for 58 positives in our series), but false positives are much more troublesome: 5 are noted in 36 cases and it seems that the real problem is confusion with cirrhosis. It is therefore necessary to follows up with arteriography, which seems to be a reliable examination in spite of the limited number of cases investigated

    To investigate whether the different location of pancreatic adenocarcinoma affects the lobar distribution of metastases to the liver. From all patients who underwent multidetector computed tomography (MDCT) examinations for staging of pancreatic adenocarcinoma in the last 4 years we selected 80 patients (42 men, 38 women; mean age, 60.56 years) with liver metastases and a pancreatic adenocarcinoma of the head (group A, 40 patients; diameter, 32.41 ± 2.28 mm) or body-tail (group B, 40 patients; diameter, 52.21 ± 2.8 mm). We analysed tumour site, diameter, vascular invasion and number of metastases in each lobe of the liver. The total number of metastases was compared between the two groups with an unpaired t-test, while Fisher's test was used to compare the number of metastases within the two lobes. As expected, the number of liver metastases was higher in group B than in group A. The ratio of metastases in the right-to-left hemi-liver was 7.4:1 for group A compared with 3.3:1 for group B (p < 0.0001). Although the number of liver metastases is higher in the right lobe than in the left lobe in both groups, there is a significant difference in the ratio of metastases between the right and the left hemi-liver. This supports the existence of a streamline phenomenon and a selective lobar distribution of metastases within the liver. (orig.)

  11. Distribution of liver metastases based on the site of primary pancreatic carcinoma

    International Nuclear Information System (INIS)

    To investigate whether the different location of pancreatic adenocarcinoma affects the lobar distribution of metastases to the liver. From all patients who underwent multidetector computed tomography (MDCT) examinations for staging of pancreatic adenocarcinoma in the last 4 years we selected 80 patients (42 men, 38 women; mean age, 60.56 years) with liver metastases and a pancreatic adenocarcinoma of the head (group A, 40 patients; diameter, 32.41 ± 2.28 mm) or body-tail (group B, 40 patients; diameter, 52.21 ± 2.8 mm). We analysed tumour site, diameter, vascular invasion and number of metastases in each lobe of the liver. The total number of metastases was compared between the two groups with an unpaired t-test, while Fisher's test was used to compare the number of metastases within the two lobes. As expected, the number of liver metastases was higher in group B than in group A. The ratio of metastases in the right-to-left hemi-liver was 7.4:1 for group A compared with 3.3:1 for group B (p < 0.0001).

  14. Abnormal expression and processing of the proprotein convertases PC1 and PC2 in human colorectal liver metastases

    International Nuclear Information System (INIS)

    The family of proprotein convertases has been recently implicated in tumorigenesis and metastasis in animal models. However, these studies have not yet been completely corroborated in human tumors. Using RT PCR, immunoblot and immunohistochemistry we assessed the presence and the processing patterns of the convertases PC1 and PC2 as well as the PC2 specific chaperone 7B2 in human liver metastases originating from colorectal cancer and compared them to unaffected and normal liver. Furthermore, we assessed the presence and processing profiles of PC1, PC2 and 7B2 in primary colon cancers. mRNA, protein expression, and protein cleavage profiles of proprotein convertases 1 and 2 are altered in liver colorectal metastasis, compared to unaffected and normal liver. Active PC1 protein is overexpressed in tumor, correlating with its mRNA profile. Moreover, the enhanced PC2 processing pattern in tumor correlates with the overexpression of its specific binding protein 7B2. These results were corroborated by immunohistochemistry. The specific and uniform convertase pattern observed in the metastases was present only in a fraction of primary colon cancers. The uniformly altered proprotein convertase profile in liver metastases is observed only in a fraction of primary colon cancers, suggesting possible selection processes involving PCs during metastasis as well as an active role of PCs in liver metastasis. In addition, the exclusive presence of 7B2 in metastatic tumors may represent a new target for early diagnosis, prognosis and/or treatment

  15. Remission of Unresectable Lung Metastases from Rectal Cancer After Herbal Medicine Treatment: A Case Report.

    Lung metastasis is frequent in rectal cancer patients and has a poor prognosis, with an expected three-year survival rate of about 10%. Though western medicine has made great strides in the curative resection of liver metastases, resection of lung metastases has lagged far behind. Many preclinical studies have suggested that herbal treatments block metastasis, but few clinical studies have addressed this topic. We present the case of a 57-year-old Asian male with lung metastases from rectal cancer. He first underwent resection of the primary lesion (stage IIA, T3N0M0) and six cycles of adjuvant chemotherapy. Unfortunately, lung metastases were confirmed about one year later. Palliative chemotherapy was begun, but his disease continued to progress after three cycles and chemotherapy was halted. The patient was exclusively treated with herbal medicine-standardized allergen-removed Rhus verniciflua stokes extract combined with Dokhwaljihwang-tang (Sasang constitutional medicine in Korea). After seven weeks of herbal medicine treatment, the lung metastases were markedly improved. Regression of lung metastases has continued; also, the patient's rectal cancer has not returned. He has been receiving herbal medicine for over two years and very few side effects have been observed. We suggest that the herbal regimen used in our patient is a promising candidate for the treatment of lung metastases secondary to rectal cancer, and we hope that this case stimulates further investigation into the efficacy of herbal treatments for metastatic colorectal cancer patients.

    2001-01-01

    Full Text Available In spite of intensive and increasingly successful attempts to determine the multiple steps involved in colorectal carcinogenesis, the mechanisms responsible for metastasis of colorectal tumors to the liver remain to be clarified. To identify genes that are candidates for involvement in the metastatic process, we analyzed genome-wide expression profiles of 10 primary colorectal cancers and their corresponding metastatic lesions by means of a cDNA microarray consisting of 9121 human genes. This analysis identified 40 genes whose expression was commonly upregulated in metastatic lesions, and 7 that were commonly downregulated. The upregulated genes encoded proteins involved in cell adhesion, or remodeling of the actin cytoskeleton. Investigation of the functions of more of the altered genes should improve our understanding of metastasis and may identify diagnostic markers and/or novel molecular targets for prevention or therapy of metastatic lesions.

  19. Local therapy of colorectal liver metastases: laser vs. direct current therapy in a rat model

    International Nuclear Information System (INIS)

    Evaluation of the efficacy of direct current and laser therapy in the treatment of colorectal liver metastases in a rat model. Materials and Methods: liver metastases in 49 rats were induced by subcapsular injection of cells of a colorectal tumor cell line. 3 weeks after inoculation 41 tumors were treated by laser and 56 tumors by direct current therapy. 17 tumors served as a control in the direct current group, 12 in the laser therapy group. The inoculation rate and the tumor size 3 and 5 weeks after therapy were determined by MRI. Results: the MR-tomographically determined inoculation rate was 133 tumors after 151 tumor cell injections (88%). Three and five weeks after laser therapy, tumor growth rates of 15% and 18% were documented (maximum tumor diameter). This represented a significant reduction in growth (p≤0.01 and p≤0.001) compared to the control group (growth rate 230% and 280%). In the direct current therapy group, growth rates were 40% after 3 and 60% after 5 weeks. Compared to the control group (210% and 290%), this also represented a significant reduction (p≤0.001). Conclusions: this animal study is the first to demonstrate an antitumor effect of direct-current therapy on liver metastases of colorectal cancer in rats. Nevertheless, the laser therapy proved to be more effective. (orig.)

  3. Treatment strategies for lung cancer brain metastases

    International Nuclear Information System (INIS)

    Forty-one patients suffered initial relapses with brain metastasis after surgery for non-small lung cancer at our hospital between 1978 and 1995. These patients were a total of 8.4% of all cases of surgical removal, and had an average relapse period of 8.6 months ± 8.0 months after surgery on the primary lesions. Of these, surgical removal of metastasized lesions was performed on 18 patients (43%), in which the 5-year post-operative survival rate was 35.7%, and the median survival time was good at 28 months. It was found that the survival period was significantly extended in the group whose relapse period was less than one year after surgery on the primary lesions, and in the group who received cranial irradiation post-operatively on the metastasized brain lesion. Following surgery on the metastasized lesion, second relapses occurred in nine patients, and six patients suffered from second relapses in the brain, of which four did not receive cranial irradiation post-operatively. Cases of radiotherapy in patients of 70 years of age or more frequently manifested post-radiotherapy subacute neuropathy. From the above, it is thought that the following procedures should be adopted: Periodic examination for brain metastasis during the 24 months following surgery for non-small cell lung carcinoma for purposes of early detection; in cases where brain metastasis is detected, if no metastasis is identified in other organs, a policy of surgical removal should be adopted where possible; and, in cases of 70 years of age or less following surgery on the metastasized lesion, cranial irradiation should be considered.

    2016-08-01

    We determined prognostic impact of KRAS, BRAF, PIK3CA and TP53 mutation status and mutation heterogeneity among 164 colorectal cancer (CRC) patients undergoing liver resections for metastatic disease. Mutation status was determined by Sanger sequencing of a total of 422 metastatic deposits. In univariate analysis, KRAS (33.5%), BRAF (6.1%) and PIK3CA (13.4%) mutations each predicted reduced median time to relapse (TTR) (7 vs. 22, 3 vs. 16 and 4 vs. 17 months; p < 0.001, 0.002 and 0.023, respectively). KRAS and BRAF mutations also predicted a reduced median disease-specific survival (DSS) (29 vs. 51 and 16 vs. 49 months; p <0.001 and 0.008, respectively). No effect of TP53 (60.4%) mutation status was observed. Postoperative, but not preoperative chemotherapy improved both TTR and DSS (p < 0.001 for both) with no interaction with gene mutation status. Among 94 patients harboring two or more metastatic deposits, 13 revealed mutation heterogeneity across metastatic deposits for at least one gene. Mutation heterogeneity predicted reduced median DSS compared to homogeneous mutations (18 vs. 37 months; p = 0.011 for all genes; 16 vs. 26 months; p < 0.001 analyzing BRAF or KRAS mutations separately). In multivariate analyses, KRAS or BRAF mutations consistently predicted poor TRR and DSS. Mutation heterogeneity robustly predicted DSS but not TTR, while postoperative chemotherapy improved both TTR and DSS. Our findings indicate that BRAF and KRAS mutations as well as mutation heterogeneity predict poor outcome in CRC patients subsequent to liver resections and might help guide treatment decisions.

  5. Does colon cancer ever metastasize to bone first? a temporal analysis of colorectal cancer progression

    International Nuclear Information System (INIS)

    It is well recognized that colorectal cancer does not frequently metastasize to bone. The aim of this retrospective study was to establish whether colorectal cancer ever bypasses other organs and metastasizes directly to bone and whether the presence of lung lesions is superior to liver as a better predictor of the likelihood and timing of bone metastasis. We performed a retrospective analysis on patients with a clinical diagnosis of colon cancer referred for staging using whole-body 18F-FDG PET and CT or PET/CT. We combined PET and CT reports from 252 individuals with information concerning patient history, other imaging modalities, and treatments to analyze disease progression. No patient had isolated osseous metastasis at the time of diagnosis, and none developed isolated bone metastasis without other organ involvement during our survey period. It took significantly longer for colorectal cancer patients to develop metastasis to the lungs (23.3 months) or to bone (21.2 months) than to the liver (9.8 months). Conclusion: Metastasis only to bone without other organ involvement in colorectal cancer patients is extremely rare, perhaps more rare than we previously thought. Our findings suggest that resistant metastasis to the lungs predicts potential disease progression to bone in the colorectal cancer population better than liver metastasis does

    Neuroendocrine tumors are uncommon cancers characterized by a slow grow rate. Unresectable liver metastases are the main cause of death in patients with these tumors. This is the first Argentine report of a liver transplantation as an indication for the treatment of unresectable liver metastases from a pancreatic neuroendocrine tumor. We present a 48-year-old woman with diagnosis of a pancreatic neuroendocrine tumor with multiple bilobar unresectable liver metastases. A splenopancreatectomy was performed after a complete staging revealed absence of extrahepatic disease. Six months later, a follow-up performed with thoracoabdominal CT scan and octreo-scan was consistent with no tumor recurrence or extrahepatic disease. As the huge hepatomegaly caused a notorius deterioration in the patient's quality of life, we decided to include her in the waiting list for liver transplantation. Priority points were requested to the MELD (model for end stage liver disease) Exceptions Experts Committee with a positive response. Twelve months after the primary surgery, with a MELD score of 23 points, a deceased donor liver transplantation was performed without evidence at that moment of residual disease. Eighteen months after liver transplantation, the patient required the surgical repair of a stenosis in the biliary anastomosis. At the surgery peritoneal tumor recurrence was diagnosed. Now, 24 months after liver transplantation the patient has an excellent quality of life and a well functioning graft. We report this case of a liver transplantation as an indication for the treatment of liver metastases from a neuroendocrine tumor and we review the literature on this controversial issue.

  9. Response assessment of colorectal liver metastases with contrast enhanced CT/18F-FDG PET

    International Nuclear Information System (INIS)

    Purpose: Evaluate the diagnostic performance of contrast enhanced CT/PET (ceCT/PET) in the response assessment of patients with colorectal cancer liver metastases. Methods: 33 ce CT/PET studies of 19 patients with colorectal liver metastases were prospectively evaluated. All of them, 13 (68.4%) were males and 6 (31.6%) females. Mean age and range were 63 [42–78]. All patients were treated with neoadjuvant chemotherapy. In all cases post-therapy diagnostic confirmation of liver lesions was obtained. A ce CT PET/was obtained 1 h after the injection of 370 MBq of 18F-FDG. Metabolic and morphologic studies were evaluated by two blinded nuclear physicians and radiologists respectively to assess the location, size and suspected diagnosis of lesions (benign or malignant). A combined assessment of both techniques was performed. The final diagnosis was established by histopathology or clinical/radiological follow-up greater than 6 months. Results: A total of 120 liver lesions were identified, 115 were malignant and 5 benign. From the malignant lesions, 105 were identified with the ceCT, 44 with the PET and 109 with ceCT/PET. All of the benign lesions were correctly classified with any of the three imaging techniques. The sensitivity of PET, ceCT and ceCT/PET were of 38%, 91% and 95% respectively and the specificity was 100% in all three of the diagnostic studies. Conclusion: Administration of intravenous contrast in the PET/CT is mandatory to evaluate treatment response rate of liver metastases due to the limitations of isolated metabolic images in these cases

    Objective:To analyze the clinical course and treatment result of lung metastases from breast cancer. Method:122 cases with lung metastases from breast cancer were treated with chemotherapy or chemotherapy plus endocrine therapy, response was assessed according to WHO criteria and survival rate estimated using the life Table. Results: The median time from initial treatment of primary tumor to lung metastases was 22 months. Sites of common consecutive metastases were lung, liver and bone. The overall response rate was 48% with a CR rate of 15%. Compared to non- DDP- encompassing regimen, the CR rate was higher in DDP-based chemotherapy (7%versus 21%, P<0.05) with a longer median survival time (MST). The PR rate was higher in regimens containing anthracycline (48%) than in those without anthracycline (20%, P<0.01). The response rate was similar between chemotherapy and chemotherapy plus endocrine therapy (P>0.05). No difference in MST was observed between patients receiving anthracycline-and non-anthracyclineencompassing regimens. The 1-, 3-, 5-, and 10-year survival rate was 77%, 22 %, 11%, and 10%, respectively.Conclusion: Size of primary tumor, the length of diseasefree interval, the number of lung metastases may provide additional information for predicting patients survival after treatment of lung metastases. Combination chemotherapy, especially DDP-based chemotherapy may prolong survival time of patients with lung metastases from breast cancer.

    The liver is the second only to lymph nodes as the most common site of metastatic disease irrespective of the primary tumor. Up to 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improvement of the survival time, only approximately 20% of the patients are eligible for surgical intervention. Radiofrequency (RF) ablation represents one of the most important alternatives as well as complementary methods for the therapy of liver metastases. RF ablation can lead in a selected patient group to a palliation or to an increased life expectancy. RF ablation appears either safer (vs. cryotherapy) or easier (vs. laser) or more effective (percutaneous ethanol instillation [PEI]), transarterial chemoembolisation [TACE] in comparison with other minimal invasive procedures. RF ablation can be performed percutaneously, laparoscopically or intraoperatively and may be combined with chemotherapy as well as with surgical resection. Permanent technical improvements of RF systems, a better understanding of the underlying electrophysiological principles and an interdisciplinary approach will lead to a prognosis improvement in patients with liver metastases.

Obito ocorreu em 22 casos (44,89%. O tipo histológico predominante foi o adenocarcinoma tubular moderadamente diferenciado em 65,96%, 17,02% pouco e 17,02% bem diferenciado. Fatores como o tipo histológico indiferenciado, menor infiltrado inflamatório peritumoral, maior reação desmoplásica e inexistência de cápsula circunscrevendo o tumor parecem compor fatores de pior prognóstico, embora não tenham sido capazes de isoladamente serem significantes Observou-se associação significante entre o nível sérico abaixo de 7 ng/ml de CEA e o sincronismo da metástase hepática. CONCLUSÕES: A ressecção cirúrgica radical das metástases hepáticas com margem de segurança superior a 10 mm promoveram maior sobrevida; os níveis séricos elevados de CEA associaram-se à recidiva tumoral das metástases e pior evolução clínica; 3. tipo histológico indiferenciado, menor infiltrado inflamatório peritumoral, maior reação desmoplásica, inexistência de cápsula circunscrevendo o tumor sugerem pior prognóstico.BACKGROUND: Colorectal cancer belongs to the most frequent malignant neoplasia in the world and responsible for the cause of death among other types of cancer; ranked second behind lung cancer. Metastasis frequently occurs and disease worsening leads to patient death. AIM: To analyze if radical surgical resection for colorectal cancer liver metastases with resection margin greater than 10 mm promotes better survival rates and the factors that might predict prognosis. METHODS: Retrospective analysis of 49 patients presenting colorectal adenocarcinoma liver metastases without evidence of concomitant disease and submitted to surgical treatment. Epidemiologic parameters were: age, gender, size of liver metastasis and or the largest lesion, number of regional lymph

  1. Stereotactic body radiation therapy (SBRT) in the treatment of liver metastases: State of the art

    International Nuclear Information System (INIS)

    Liver metastases are frequently found in oncologic patients. Chemotherapy is the standard treatment in pluri-metastatic patients, with the possibility to obtain a clear improvement of their prognosis. Local treatment (surgery, radiofrequency, cryo-therapy, radiotherapy, etc.) could be proposed for oligo-metastatic patients, particularly for those with a good prognosis. Historically, radiation therapy has had a limited role in the treatment of liver metastases because of its toxicity when whole liver irradiation was delivered. Improvements in the knowledge of liver radiobiology and radio-pathology as well as technical innovations in delivering radiation therapy are the basis of the modern partial liver irradiation concept. In this historical and therapeutic landscape, extracranial stereotactic radiation therapy is particularly interesting for the treatment of liver metastases. This review summarises published data on stereotactic radiotherapy for the treatment of liver metastases. (authors)

    Cancer-associated fibroblasts (CAFs) represent the predominant cell type of the neoplastic stroma of solid tumors, yet their biology and functional specificity for cancer pathogenesis remain unclear. We show here that primary CAFs from colorectal liver metastases express several inflammatory, tumor-enhancing factors, including interleukin (IL)-6 and monocyte-chemoattractant protein (MCP)-1. Both molecules were intensely induced by TNF-{alpha} on the transcript and protein level, whereas PDGF-BB, TGF-{beta}1 and EGF showed no significant effects. To verify their potential specialization for metastasis progression, CAFs were compared to fibroblasts from non-tumor liver tissue. Interestingly, these liver fibroblasts (LFs) displayed similar functions. Further analyses revealed a comparable up-regulation of intercellular adhesion molecule-1 (ICAM-1) by TNF-{alpha}, and of alpha-smooth muscle actin, by TGF-{beta}1. Moreover, the proliferation of both cell types was induced by PDGF-BB, and CAFs and LFs displayed an equivalent migration towards HT29 colon cancer cells in Boyden chamber assays. In conclusion, colorectal liver metastasis may be supported by CAFs and resident fibroblastic cells competent to generate a prometastatic microenvironment through inflammatory activation of IL-6 and MCP-1.

  4. Evaluation of a gadolinium-based nanoparticle (AGuIX) for contrast-enhanced MRI of the liver in a rat model of hepatic colorectal cancer metastases at 9.4 tesla

    International Nuclear Information System (INIS)

    The aim of this study was to compare a Gd-based nanoparticle (AGuIX) with a standard extracellular Gd-based contrast agent (Gd-DOTA) for MRI at 9.4 T in rats with hepatic colorectal cancer metastases. 12 rats with hepatic metastases were subjected to MRI using a 9.4 T animal scanner. T1w self-gated FLASH sequences (TR/TE=45/2.5 ms, alpha = 45 , TA=1: 23 min, FOV=5.12 x 5.12 cm2, matrix = 256 x 256) were acquired before and at 10 time points after contrast injection. Each animal received 0.1 mmol/kg BW Gd-DOTA i.v. 2 days later AGuIX was applied at 0.01 mmol/kg BW (representing equal Gd doses). The SNR of normal liver (SNRliver), hyper- and hypoenhancing parts of tumors (SNRtumor, hyperenh/SNRtumor, hypoenhanc), erector spinae muscle (SNRmuscle), CNR and lesion enhancement (LE) were calculated based on ROI measurements. Mean SNRliver (Gd-DOTA: 14.6 ± 0.7; AGuIX: 28.2 ± 2.6, p < 0.001), SNRtumor, hyperenhanc (Gd-DOTA: 18.6 ± 1.2; AGuIX: 29.6 ± 2.8, p < 0.001), SNRtumor, hypoenhanc (Gd-DOTA: 12.0 ± 0.7; AGuIX: 15.4 ± 0.7, p < 0.001), SNRmuscle (Gd-DOTA: 12.3 ± 0.3; AGuIX: 14.0 ± 0.7, p < 0.001), mean CNR (Gd-DOTA: -2.5 ± 0.2; AGuIX: -7.5 ± 1.0, p < 0.001) and LE (Gd-DOTA: 3.8 ± 0.7; AGuIX: 14.9 ± 2.8, p=0.001) were significantly higher using AGuIX. Regardless of the larger molecular size, AGuIX demonstrates an early peak enhancement followed by a continuous washout. AGuIX provides better enhancement at 9.4 T compared to Gd-DOTA for equal doses of applied Gd. This is based on the molecule structure and the subsequent increased interaction with protons leading to a higher relaxivity. AGuIX potentially ameliorates the conspicuity of focal liver lesions and may improve the sensitivity in diagnostic imaging of malignant hepatic tumors.

  7. Clinical effect of percutaneous radiofrequency ablation for residual lung metastases from breast cancer after systemic chemotherapy

    International Nuclear Information System (INIS)

    Objective: To determine the clinical effect of Radiofrequency Ablation (RFA) for residual lung metastases from breast cancer after systemic chemotherapy. Study Design: An experimental study. Place and Duration of Study: The Second Affiliated Hospital of Soochow University, Suzhou, Fudan University Shanghai Cancer Center, Shanghai, China, from January 2008 to October 2014. Methodology: Thirty-five breast cancer patients with 67 pulmonary metastases were involved in this study. All lesions were treated by RFA and followed by CT-scan. Primary endpoint of this clinical study was local control; secondary endpoints were overall survival and treatment-related toxicities. Results: Complete Response (CR) was observed in 59 lesions, with Partial Response (PR) in 4 lesions, Stable Disease (SD) in 1 lesion and Progression Disease (PD) in 3 lesions. The lesion diameter > 2 cm was related to poor local control (p=0.04). The median Overall Survival (OS) was 33 months (95%CI: 21.6 - 44.4). One, 2-, and 3-year OS rates were 88.6%, 59.3% and 42.8% respectively. The mumber of pulmonary metastases (2), the diameter of lesion (> 2 cm) and coexisting with liver metastases were significantly correlated to poor OS by multivariate analysis. Log-rank test showed statistically significant difference of OS in diameter of lesion and coexisting with other metastases. Conclusion: RFA is a promising treatment option for patients with residual lung metastases from breast cancer after systemic chemotherapy in selected patients. (author)

  8. Stereotactic body radiation therapy for liver primary and metastases: The Lille experience

    International Nuclear Information System (INIS)

    Purpose. - The CyberKnifeR system is a recent radiation therapy technique that allows treatment of liver lesions with real-time tracking. Because of its high precision, the dose administered to the tumor can be increased. We report Oscar-Lambret Cancer Centre experience in the treatment of primary and secondary liver lesions. Patients and methods. - It is a retrospective study analyzing all the patients who have been treated for their liver lesions since July 2007. A hundred and twenty patients have been treated: 42 for hepatocellular carcinoma, 72 for liver metastases and six for cholangio-carcinoma. Gold seeds need to be implanted before the treatment and are used as markers to follow the movement of the lesion due to respiration. On average, the treatment is administered in three to four sessions over 12 days. A total dose of 40 to 45 Gy at the 80% isodose is delivered. Local control and overall survival analysis with Log-rank is performed for each type of lesion. Results. - Treatment tolerance is good. The most common toxicities are of digestive type, pain and asthenia. Six gastro-duodenal ulcers and two radiation-induced liver disease (RILD) were observed. At a median follow-up of 15 months, the local control rate is respectively of 80.4% and 72.5% at 1 and 2 years. Overall survival is 84.6 and 58.3% at 1 and 2 years. The local control is significantly better for the hepatocellular carcinoma and overall survival is significantly better for liver metastases (P R is a promising technique, well tolerated, with tumoral local control rates comparable to other techniques. Its advantage is that it is very minimally invasive delivered as an outpatient procedure in a frail population of patient (disease, age). (authors)

    BACKGROUND: Hepatoid tumors (HTs) are rare extra-hepatic neoplasms with the histological features, biochemical proifle and, sometimes, even clinical course of hepatocellular carcinoma. We present a case of rectal hepatoid adenocarcinoma with metachronous liver metastases. METHODS: Four months after total procto-colectomy for a rectal adenocarcinoma (Astler-Coller C2), a 42-year-old man with ulcerative colitis showed hypoechoic masses in the hepatic parenchyma by abdominal ultrasonography. Carcinoembryonic antigen was normal, but alpha-fetoprotein was 32 000 μg/L. Fine-needle biopsy revealed that liver masses were positive for hepatocellular carcinoma. The patient underwent left hepatectomy and alcoholisation of a small deep nodule in segment 8. RESULTS:  Immunohistochemistry and albumin mRNA in situ hybridization suggested that the nodules were metastases of a HT. The patient was well during the ifrst 6 months and refused any adjuvant chemotherapy. He died from liver failure 19 months after initial diagnosis. CONCLUSIONS: HT is a rare colon cancer. The preoperative diagnosis of this tumor requires a high degree of suspicion, the availability of a panel of immunohistochemical markers, and a certain amount of luck. The prognosis is poor despite an aggressive and multimodal therapeutic strategy. So far, none of the hypotheses proposed about the origin and the biology of these tumors is convincing.

  14. Update on the optimal management of patients with colorectal liver metastases.

    2012-10-01

    Patients with colorectal liver metastases represent a distinct subset of metastatic colorectal cancer. Optimal management requires a multidisciplinary approach, local and systemic. Curative hepatic surgery is standard for resectable cases, but unfortunately, the majority of patients are not initially resectable due to the size, location, and/or extent of disease, inadequate remnant liver volume, or comorbidities. Other local approaches may be complementary (such as portal vein embolization) or alternative (such as ablation, hepatic arterial infusion, selective internal radiation therapy, and stereotactic body radiotherapy) to surgery. Systemic therapy can downsize disease, allowing surgical resection and, potentially, long-term survival, but it must be balanced against the potential for hepatotoxicity. Current standard approaches including cytotoxics and biologics, such as bevacizumab and particularly anti-epidermal growth factor receptor therapy, improve response rates and may enhance downsizing and resection rates. Optimization of local therapies and systemic conversion strategies via controlled, randomized trials is still a pending question. PMID:22425016

  15. PTEN expression is consistent in colorectal cancer primaries and metastases and associates with patient survival

    International Nuclear Information System (INIS)

    Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) negatively regulates the phosphoinositide-3-kinase (PI3K) signaling pathway. In colorectal cancer (CRC), observed frequencies of loss of PTEN expression, concordant expression in primary tumors and metastases, and the association of PTEN status with outcome vary markedly by detection method. We determined the degree to which PTEN expression is consistent in 70 matched human CRC primaries and liver metastases using a validated immunohistochemistry assay. We found loss of PTEN expression in 12.3% of assessable CRC primaries and 10.3% of assessable liver metastases. PTEN expression (positive or negative) was concordant in 98% of matched colorectal primaries and liver metastases. Next we related PTEN status to mutations in RAS and PI3K pathway genes (KRAS, NRAS, BRAF, and PIK3CA) and to overall survival (OS). PTEN expression was not significantly associated with the presence or absence of mutations in RAS or PI3K pathway genes. The median OS of patients whose tumors did not express PTEN was 9 months, compared to 49 months for patients whose tumors did express PTEN (HR = 6.25, 95% confidence intervals (CI) (1.98, 15.42), P = 0.0017). The association of absent PTEN expression with increased risk of death remained significant in multivariate analysis (HR = 6.31, 95% CI (2.03, 17.93), P = 0.0023). In summary, PTEN expression was consistent in matched CRC primaries and in liver metastases. Therefore, future investigations of PTEN in metastatic CRC can use primary tumor tissue. In patients with liver-only metastases, loss of PTEN expression predicted poor OS. We observed concordant PTEN expression in 98% of colorectal cancer (CRC) primary and liver metastasis pairs using a validated immunohistochemistry assay. Consistent PTEN expression at both disease sites is significant because tumor tissue is usually available from CRC primaries but not metastases. Loss of PTEN expression associated with poor survival of

    Proteoglycans are a group of molecules that contain at least one glycosaminoglycan chain, such as a heparan, dermatan, chondroitin, or keratan sulfate, covalently attached to the protein core. These molecules are categorized based on their structure, localization, and function, and can be found in the extracellular matrix, on the cell surface, and in the cytoplasm. Cell-surface heparan sulfate proteoglycans, such as syndecans, are the primary type present in healthy liver tissue. However, deterioration of the liver results in overproduction of other proteoglycan types. The purpose of this article is to provide a current summary of the most relevant data implicating proteoglycans in the development and progression of human and experimental liver cancer. A review of our work and other studies in the literature indicate that deterioration of liver function is accompanied by an increase in the amount of chondroitin sulfate proteoglycans. The alteration of proteoglycan composition interferes with the physiologic function of the liver on several levels. This article details and discusses the roles of syndecan-1, glypicans, agrin, perlecan, collagen XVIII/endostatin, endocan, serglycin, decorin, biglycan, asporin, fibromodulin, lumican, and versican in liver function. Specifically, glypicans, agrin, and versican play significant roles in the development of liver cancer. Conversely, the presence of decorin could potentially provide protective effects.

    This study aimed to determine factors allowing the prediction of extracranial metastases in patients presenting with brain metastases at the first diagnosis of cancer. Data from 659 patients with brain metastases upon first diagnosis of cancer were retrospectively analyzed. The parameters age, gender, Karnofsky performance score (KPS), primary tumor type and number of brain metastases were compared between 359 patients with extracranial metastases and 300 patients without extracranial metastases. Additional analyses were performed for patients with the most unfavorable and those with the most favorable characteristics. The comparison of patients with versus without extracranial metastases revealed significant differences between the groups in terms of KPS (p < 0.001) and number of brain metastases (p < 0.001). Of the study patients, 113 had both most unfavorable characteristics, i.e. KPS ≤ 50 and ≥ 4 brain metastases. The sensitivity for identifying patients with extracranial metastases was 82 %; specificity was 51 %. A total of 50 patients had KPS ≥ 90 and only one brain metastasis. The sensitivity for identifying patients without extracranial metastases was 86 %; specificity was 58 %. The combination of KPS and the number of brain metastases can help to predict the presence or absence of extracranial metastases. (orig.)

    Risks of tumor recurrence after surgical resection have been known for decades, but the mechanisms underlying treatment failures remain poorly understood. Neutrophils, first-line responders after surgical stress, may play an important role in linking inflammation to cancer progression. In response to stress, neutrophils can expel their protein-studded chromatin to form local snares known as neutrophil extracellular traps (NET). In this study, we asked whether, as a result of its ability to ensnare moving cells, NET formation might promote metastasis after surgical stress. Consistent with this hypothesis, in a cohort of patients undergoing attempted curative liver resection for metastatic colorectal cancer, we observed that increased postoperative NET formation was associated with a >4-fold reduction in disease-free survival. In like manner, in a murine model of surgical stress employing liver ischemia-reperfusion, we observed an increase in NET formation that correlated with an accelerated development and progression of metastatic disease. These effects were abrogated by inhibiting NET formation in mice through either local treatment with DNAse or inhibition of the enzyme peptidylarginine deaminase, which is essential for NET formation. In growing metastatic tumors, we found that intratumoral hypoxia accentuated NET formation. Mechanistic investigations in vitro indicated that mouse neutrophil-derived NET triggered HMGB1 release and activated TLR9-dependent pathways in cancer cells to promote their adhesion, proliferation, migration, and invasion. Taken together, our findings implicate NET in the development of liver metastases after surgical stress, suggesting that their elimination may reduce risks of tumor relapse. PMID:26759232

  2. T cells but not NK cells are associated with a favourable outcome for resected colorectal liver metastases

    International Nuclear Information System (INIS)

    The adaptive immune response to colorectal cancer is important for survival. Less is understood about the role of innate lymphocytes, such as Natural Killer (NK) cells, which are abundant in human liver. Samples of fresh liver (n = 21) and tumour (n = 11) tissue were obtained from patients undergoing surgical resection of colorectal liver metastases. Flow cytometry was used to analyse the presence and phenotype of NK cells, as compared to T cells, in the tumour and liver tissue. Results were correlated with survival. NK cells were poorly recruited to the tumours (distant liver tissue 38.3%, peritumoural liver 34.2%, tumour 12.9%, p = 0.0068). Intrahepatic and intratumoural NK cells were KIR (killer immunoglobulin-like receptor)loNKG2Ahi whereas circulating NK cells were KIRhiNKG2Alo. By contrast T cells represented 65.7% of the tumour infiltrating lymphocytes. Overall survival was 43% at 5 years, with the 5-year survival for individuals with a T cell rich infiltrate being 60% (95% CI 17-93%) and for those with a low T cell infiltrate being 0% (95% CI 0-48%). Conversely individuals with higher levels of NK cells in the tumour had an inferior outcome, although there were insufficient numbers to reach significance (median survivals: NKHi 1.63 years vs NKLo 3.92 years). T cells, but not NK cells, are preferentially recruited to colorectal liver metastases. NK cells within colorectal metastases have an intrahepatic and potentially tolerogenic, rather than a peripheral, phenotype. Similar to primary tumours, the magnitude of the T cell infiltrate in colorectal metastases is positively associated with survival

  3. Can the National Health Service Cancer Plan timeline be applied to colorectal hepatic metastases?

    LENUS (Irish Health Repository)

    2012-02-01

    INTRODUCTION: The National Health Service (NHS) Cancer Plan guidelines recommend a maximum 2-week wait from referral to first appointment, and 2 months from referral to treatment for primary cancers. However, there are currently no guidelines available for metastatic disease. In the UK, nearly half of all colorectal cancer patients develop hepatic metastases. Timely, surgical resection offers the potential for cure. The aim of this study was to audit current practice for colorectal liver metastases in a regional hepatobiliary unit, and compare this to the NHS Cancer Plan standards for primary disease. PATIENTS AND METHODS: A retrospective review of the unit\\'s database was performed for all hepatic metastases referrals from January 2006 to December 2008. The dates of referral, first appointment, investigations and initiation of treatment, along with patient\\'s age and sex, were recorded on Microsoft Excel and analysed. Time was expressed as mean +\\/- SD in days. RESULTS: A total of 102 patients with hepatic metastases were identified. Five were excluded due to incomplete data. The average time from referral to first appointment was 10.6 +\\/- 9.4 days and the average time from referral to treatment was 38.5 +\\/- 28.6 days. Seventy-five (72.7%) had surgical intervention, of whom 37 also had chemotherapy. CONCLUSIONS: The data compare favourably to the NHS Cancer Plan guidelines for primary malignancy, demonstrating that a regional hepatobiliary unit is capable of delivering a service for colorectal liver metastases that adheres to the NHS Cancer Plan. Therefore, the NHS Cancer Plan can be applied to this cohort.

  6. Pulmonary nodules and metastases in colorectal cancer.

    Nordholm-Carstensen, Andreas

    2016-01-01

    Patients with newly diagnosed colorectal cancer (CRC) are subjected to a preoperative thoraco-abdominal CT scan to determine the cancer stage. This staging is of relevance with regard to treatment and prognosis. About 20% of the patients have distant metastatic spread at the time of diagnosis, i.e. synchronous metastases. Most common are hepatic metastases followed by pulmonary involvement. The optimal staging modality for detecting synchronous pulmonary metastases is debated. It has been argued, that synchronous pulmonary metastases (SPCM) are rare in CRC and that the consequence of detecting SPCM is minimal. Furthermore, the current staging practice is complicated by a high number of incidental findings on the thoracic CT, so-called indeterminate pulmonary nodules (IPN). IPN can potentially represent SPCM. The purpose of this thesis was to estimate the prevalence, characteristics and clinical significance of IPN and SPCM detected at the primary staging in CRC. Study I was a systematic review of published studies on IPN in CRC focusing on the prevalence and radiological characteristics of IPN proving to be malignant. This knowledge would be of value in management strategies for IPN. On average 9% of all patients staged with a thoracic CT had IPN, however, the prevalence varied significantly between patients series. This was mainly attributed to varying/lacking definitions on IPN and variable radiological expertise in the assessment of the scans. Data were too inconsistently reported in the case series for a robust statement to be made on potential radiological characteristics suggestive of malignancy in IPN. Lymph node metastasis was the most common clinicopathological finding associated with malignancy of IPN. In conclusion, one patient of every 100 scanned patients had an IPN proving to a SPCM at follow-up, but we found no evidence that IPN should result in intensified diagnostic work-up besides routine follow-up for CRC. Study II was an analysis of the

  7. Computed tomography in brain metastases of colorectal cancer

    International Nuclear Information System (INIS)

    Metastatic brain tumors from colorectal cancers are relatively rare. In previous reports, the incidence ranged from 3 to 5 percent of all metastatic brain tumors. We report 7 cases of metastatic brain tumors from colorectal cancers. The time interval from the diagnosis of the primary tumors to the brain metastasis was 3 years on the average. Metastasis to the lung and liver were also found in 6 cases at the time of the diagnosis of the brain metastasis. The CEA levels in the serum were highly elevated in all cases. Solitary metastasis was found in all cases; cancers tend to metastasize in the deep area of the cerebrum or cerebellum. On a plain CT scan, tumors were demonstrated as ring-type, with a high-density mass, and ring-like enhancement was seen in 6 cases. Prognosis was very poor in most cases. The median survival time from diagnosis of brain metastasis was 4.5 months in the 2 cases with surgery and 3.5 months in the 4 cases without surgery. (author)

    In order to discuss the role of preoperative chemotherapy for colorectal liver metastases, which is used frequently before hepatic resection, even in patients with resectable disease at presentation, we herein report the development of two complications, partial portal vein thrombosis and hepatic steatosis with lobular inflammation, during the course of preoperative chemotherapy with FOLFIRI plus bevacizumab for colorectal liver metastases, which recognition led to timely discontinuation of chemotherapy as well as a change in the surgical strategy to resect the tumors and the damaged liver through advanced techniques.We conclude that duration of treatment and drug doses and combinations may impact the development of chemotherapy-induced liver injury. Surgeons and medical oncologists must work together to devise safe, rational,and oncologically appropriate treatments for patients with multiple colorectal liver metastases, and to improve the understanding of the pathogenesis of chemotherapyinduced liver injury.

  9. Predisposing Factors of Liver Necrosis after Transcatheter Arterial Chemoembolization in Liver Metastases from Neuroendocrine Tumor

    International Nuclear Information System (INIS)

    PurposeTo investigate predictive factors for liver necrosis after transcatheter arterial chemoembolization (TACE) of neuroendocrine liver metastases.MethodsA total of 164 patients receiving 374 TACE were reviewed retrospectively to analyze predictive factors of liver necrosis. We analyzed patient age and sex; metastasis number and location; percentage of liver involvement; baseline liver function test; and pretreatment imaging abnormalities such as bile duct dilatation (BDD), portal vein narrowing (PVN), and portal vein thrombosis (PVT). We analyzed TACE technique such as Lipiodol or drug-eluting beads (DEB) as the drug’s vector; dose of chemotherapy; diameter of DEB; and number, frequency, and selectivity of TACE.ResultsLiver necrosis developed after 23 (6.1 %) of 374 TACE. In multivariate analysis, DEB > 300 μm in size induced more liver necrosis compared to Lipiodol (odds ratio [OR] 35.20; p < 0.0001) or with DEB < 300 μm in size (OR 19.95; p < 0.010). Pretreatment BDD (OR 119.64; p < 0.0001) and PVT (OR 9.83; p = 0.030) were predictive of liver necrosis. BDD or PVT responsible for liver necrosis were present before TACE in 59 % (13 of 22) and were induced by a previous TACE in 41 % (9 of 22) of cases.ConclusionDEB > 300 μm in size, BDD, and PVT are responsible for increased rate of liver necrosis after TACE. Careful analysis of BDD or PVT on pretreatment images as well as images taken between two courses can help avoid TACE complications

    Full Text Available Treatment results of low rectal cancer patient with internal sphincter involvement and synchronous liver metastases is presented. After combined treatment including preoperative targeted therapy, chemotherapy, chemoradiotherapy a synchronous resection of primary tumour and liver metastases was carried out (R0. Synchronous right hepihepatectomy and proctectomy was performed with resection of the deep part of external sphincter, neorectum creation by transverse coloplasty, neoanal sphincter creation using colonic smooth muscle layer without preventive colostomy. A possibility of synchronous plastic sphincter-sparing surgery in metastatic rectal cancer patient with locally advanced tumour is demonstrated. Such treatment allows to remove the risk of primary tumour complications, facilitates further chemotherapy treatment and improves quality of life and long-term treatment outcome.

    Primary tumor excision is one of the most widely used therapies of cancer. However, the risk of metastases development still exists following tumor resection. The liver is a common site of metastatic disease for numerous cancers. Breast cancer is one of the most frequent sources of metastases to the liver. The aim of this work was to evaluate the efficacy of the orally administered Salmonella Typhi vaccine strain CVD 915 on the development of liver metastases in a mouse model of breast cancer. To this end, one group of BALB/c mice was orogastrically immunized with CVD 915, while another received PBS as a control. After 24 h, mice were injected with LM3 mammary adenocarcinoma cells into the spleen and subjected to splenectomy. This oral Salmonella-based vaccine produced an antitumor effect, leading to a decrease in the number and volume of liver metastases. Immunization with Salmonella induced an early cellular immune response in mice. This innate stimulation rendered a large production of IFN-γ by intrahepatic immune cells (IHIC) detected within 24 h. An antitumor adaptive immunity was found in the liver and celiac and portal lymph nodes (LDLN) 21 days after oral bacterial inoculation. The antitumor immune response inside the liver was associated with increased CD4+ and dendritic cell populations as well as with an inflammatory infiltrate located around liver metastatic nodules. Enlarged levels of inflammatory cytokines (IFN-γ and TNF) were also detected in IHIC. Furthermore, a tumor-specific production of IFN-γ and TNF as well as tumor-specific IFN-γ-producing CD8 T cells (CD8+IFN-γ+) were found in the celiac and portal lymph nodes of Salmonella-treated mice. This study provides first evidence for the involvement of LDLN in the development of an efficient cellular immune response against hepatic tumors, which resulted in the elimination of liver metastases after oral Salmonella-based vaccination.

  8. Palliative radiotherapy for cancers other than brain or bone metastases

    International Nuclear Information System (INIS)

    Radiotherapy plays a major role in the palliation of patients with uncontrolled cancer and is important in any comprehensive care program. There are fewer phase III trials on palliative radiotherapy of other symptomatic tumors than there are for the treatment of bone metastases. However, the number of such trials has been increasing, especially for the treatment of lung cancer. In particular, symptoms from bronchial obstruction, superior vena cava obstruction and other solid tumors as well as cancer-related bone pain and brain metastases can all be palliated effectively with radiotherapy.

  9. Brain metastases from esophageal cancers. Clinical features and treatment results

    International Nuclear Information System (INIS)

    Metastatic brain tumors from esophageal cancer are relatively rare. We analyzed the clinical features and results of treatment in 14 cases of brain metastases from esophageal carcinoma. The average time to diagnosis of brain metastases in the 11 patients with metachronous lesions was 13 months. The average age of patients at the diagnosis of brain metastasis was 65 years. Most patients had T4 or N1 disease at the time of diagnosis of esophageal cancer. Performance status of grade 3 was most frequent at the time of diagnosis of brain metastasis. Treatment for brain metastases was surgery followed by radiation in five cases, radiotherapy alone in seven cases, and conservative treatment in two cases. The median survival time of all patients from the treatment of brain metastases was 2 months, with only one patient alive after more than one year. Improvement in neurological symptoms was demonstrated in 42% of cases. These extremely poor treatment results reflect the fact that most patients at the time of diagnosis of brain metastasis had poor performance status and the presence of extracerebral metastases. Therefore, a short-course, high-dose-per-fraction treatment for brain metastases from esophageal cancer should be selected from the viewpoint of quality of life. (author)

Fifty patients aged 62 ± 9.3 years were included between 2003 and 2007. Thir...

  11. Towards a new therapy protocol for liver metastases. Effect of boron compounds and BNCT on normal liver regeneration

    International Nuclear Information System (INIS)

    The Taormina project developed a new method for BNCT treatment of multifocal unresectable liver metastases based on whole liver autograft. The Roffo Institute liver surgeons propose a new technique based on partial liver autograft that would pose less risk to the patient but would require significant healthy liver regeneration following BNCT. The aim of the present study was to assess the effect of BPA, GB-10 (Na210B10H10) and (GB-10 + BPA) and of BNCT mediated by these boron compounds on normal liver regeneration in the Wistar rat. Normal liver regeneration, body weight, hemogram, liver and kidney function were assessed following partial hepatectomy post administration of BPA, GB-10 or (GB-10 + BPA) and post in vivo BNCT at the RA-6 Reactor. These end-points were evaluated 9 days following partial hepatectomy, the time at which complete liver regeneration occurs in untreated controls. The corresponding biodistribution studies were conducted to perform dosimetric calculations. BPA, GB-10 and (GB-10 + PBA) and in vivo BNCT mediated by these boron compounds in dose ranges compatible with therapy did not cause alterations in the outcome of normal liver regeneration, and did not induce alterations in body weight, hemogram, liver or kidney function. The experimental data available to date support the development of a new BNCT protocol for the treatment of liver metastases that requires the regeneration of normal liver past-BNCT. (author)

  13. Treatment options in patients with small-cell lung cancer and brain metastases

    International Nuclear Information System (INIS)

    Small cell lung cancer (SCLC) accounts for some 20-25% of all lung cancers, with some 60-70% of patients presenting with the extensive stage (ES) of SCLC at the time of the diagnosis. Brain metastases are observed in 10-35% patients with ES SCLC, and 33% of them are asymptomatic. The main method of treatment in case of ES SCLC patients is cisplatin-containing systemic therapy. Radiotherapy is used as palliative treatment (primary tumour in chest, metastases localized in bones, brain or spinal cord) or as a prophylactic procedure (prophylactic cranial irradiation).The purpose of paper is to present the treatment possibilities in case of ES SCLC patients with brain metastases. Between 1995 and 2005 at the Oncology Centre in Krakow we evaluated 170 patients with SCLC in order to establish the stage of the disease recognising 39 cases (22.9%) with the extensive stage of the disease. The most frequent localizations of distant metastases were: the brain (11 patients, of whom 3 developed brain metastases without clinical symptoms), liver (10 patients), and bones (10 patients). Further analysis has been performed in the group of patients with brain metastases. In these patients treatment based on palliative irradiation of the whole brain and on chemotherapy according to the EP (etoposide and cisplatine) regimen. For cranial irradiation the dose of 20 Gy was given in 5 fractions. In 3 patients with brain metastases without clinical symptoms radiotherapy of brain was repeated after a 4-week interruption. These patients received 5-6 cycles of EP chemotherapy, followed by consolidation radiotherapy of the primary tumour region in the chest. Overall survival was estimated at 2 to 19 months (median: 8.9 months). In the subgroup of 3 patients with brain metastases without clinical symptoms we observed complete regression within the primary tumour region and of the brain metastases. These results were confirmed radiologically. In these patients disease-free survival of 5-9 months

    Full Text Available OBJECTIVE: To investigate clinical and laboratory toxicity in patients with unresectable liver metastases, treated with yttrium-90 radioembolization ((90Y-RE. METHODS: Patients with liver metastases treated with (90Y-RE, between February 1(st 2009 and March 31(st 2012, were included in this study. Clinical toxicity assessment was based on the reporting in patient's charts. Laboratory investigations at baseline and during a four-month follow-up were used to assess laboratory toxicity according to the Common Terminology Criteria for Adverse Events version 4.02. The occurrence of grade 3-4 laboratory toxicity was stratified according to treatment strategy (whole liver treatment in one session versus sequential sessions. Response assessment was performed at the level of target lesions, whole liver and overall response in accordance with RECIST 1.1 at 3- and 6 months post-treatment. Median time to progression (TTP and overall survival were calculated by Kaplan-Meier analysis. RESULTS: A total of 59 patients, with liver metastases from colorectal cancer (n = 30, neuroendocrine tumors (NET (n = 6 and other primary tumors (n = 23 were included. Clinical toxicity after (90Y-RE treatment was confined to grade 1-2 events, predominantly post-embolization symptoms. No grade 3-4 clinical toxicity was observed, whereas laboratory toxicity grade 3-4 was observed in 38% of patients. Whole liver treatment in one session was not associated with increased laboratory toxicity. Three-months disease control rates for target lesions, whole liver and overall response were 35%, 21% and 19% respectively. Median TTP was 6.2 months for target lesions, 3.3 months for the whole liver and 3.0 months for overall response. Median overall survival was 8.9 months. CONCLUSION: The risk of severe complications or grade 3-4 clinical toxicity in patients with liver metastases of various primary tumors undergoing (90Y-RE is low. In contrast, laboratory toxicity grade 3

    Full Text Available In breast cancer patients, bone is the most common site of metastases. Medical therapies are the basic therapy to prevent distant metastases and recurrence and to cure them. Radiotherapy has a primary role in pain relief, recalcification and stabilization of the bone, as well as the reduction of the risk of complications (e.g., bone fractures, spinal cord compression. Bisphosphonates, as potent inhibitors of osteoclastic-mediated bone resorption are a well-established, standard-of-care treatment option to reduce the frequency, severity and time of onset of the skeletal related events in breast cancer patients with bone metastases. Moreover bisphosphonates prevent cancer treatment-induced bone loss. Recent data shows the anti-tumor activity of bisphosphonates, in particular, in postmenopausal women and in older premenopausal women with hormone-sensitive disease treated with ovarian suppression. Pain is the most frequent symptom reported in patients with bone metastases, and its prevention and treatment must be considered at any stage of the disease. The prevention and treatment of bone metastases in breast cancer must consider an integrated multidisciplinary approach.

  16. MR manifestations and diagnosis of brain metastases of lung cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the MRI diagnosis of brain metastases of lung cancer. Methods: MR findings of 45 patients with brain metastases of lung cancer confirmed by pathological examinations were studied retrospectively. Both non-contrast and contrast-enhanced scans were performed in all cases, in which 0.2 mmol/kg of Gd-DTPA was administrated in 40 patients and 0.1 mmol/kg in 5 patients. Results: The brain metastases of lung cancer were solitary or multiple, and round or oval in shape. Peri-lesion brain edema may present or absent. The location of metastases were mainly in supratentorial areas between the cortex and white matter but also were frequently seen in cerebella. Contrast-enhanced imaging revealed not only the lesions silent in non-enhanced scan, but also shown more nodules in 85% of patients. Conclusion: MRI, especially with contrast-enhanced imaging was a very good diagnostic modality for detecting brain metastases of lung cancer

    Full Text Available Background: Imatinib mesylate represents a real major paradigm shift in cancer therapy, targeting the specific molecular abnormalities, crucial in the etiology of tumor. Intra-arterial hepatic chemotherapy (IAHC followed by embolization, has been considered an interesting palliative option for patients with liver metastases from gastrointestinal stromal tumor (GIST, due to the typically hypervascular pattern of the tumor. Aims: We report our experience with IAHC followed by Imatinib mesylate, in order to show the superiority of the specific molecular approach in liver metastases from GIST. Materials and Methods: Three patients (pts with pretreated massive liver metastases from GIST, received IAHC with Epirubicin 50 mg/mq, every 3 weeks for 6 cycles. At the evidence of progression, they received Imatinib mesylate. Results: We observed progressive diseases in all cases. In 1998, one patient underwent Thalidomide at 150 mg orally, every day for 4 months, with evidence of stable disease and clinical improvement. In 2001, two patients received Imatinib mesylate at 400 mg orally, every day, with evidence of partial response lasting 18+ months and 16 months. One of them had grade 3 neutropenia, with suspension of therapy for 3 weeks. Conclusion: No patient treated with IAHC, reported objective responses, but two of them obtained partial response after the assumption of Imatinib mesylate and one showed temporary stabilization with thalidomide. Imatinib mesylate represents a new opportunity in GIST therapy, targeting the specific molecular alteration. It seems to be superior to conventional intra arterial hepatic chemotherapy.

    Liver is one of the most important organs in energy metabolism.Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver.It depends on the integrity of liver cellular function,which ensures homeostasis of lipid and lipoprotein metabolism.When liver cancer occurs,these processes are impaired and the plasma lipid and lipoprotein patterns may be changed.Liver cancer is the fifth common malignant tumor worldwide,and is closely related to the infections of hepatitis B virus (HBV) and hepatitis C virus (HCV).HBV and HCV infections are quite common in China and other Southeast Asian countries.In addition,liver cancer is often followed by a procession of chronic hepatitis or cirrhosis,so that hepatic function is damaged obviously on these bases,which may significantly influence lipid and lipoprotein metabolism in vivo.In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer.

  19. Combination radiation therapy for bone metastases in thyroid cancer

    International Nuclear Information System (INIS)

    Full text: Distant metastases of thyroid carcinoma (TC) occur due to dissemination of cancer cells through the lymph and blood vessels. They develop in 10-15% of patients with differentiated thyroid carcinoma and are the main cause of death in cancer patients. Appearance of distant metastases depends on a number of factors, i.e. the age of the patients (chiefly in children and those over 45); small size tumors; invasive growth of the tumor outside the thyroid capsule; involvement of the sentinel lymph nodes; poor differentiation of the tumor; incomplete surgical removal of the tumor. Distant metastases mainly localize in the lungs and/or bones. In thyroid cancer patients with suspected bone metastases the latter are revealed radiologically on the primary examination (approximately in 95.9% of cases). In 25% of them, they are seen at body scan with I-131 on residual activities. Probability of visualization of iodine-positive bone metastases is higher at ablation of residual thyroid tissue. When the metastases are revealed by x-ray study, they cannot be treated using I-131, which emphasizes the necessity of other methods of treatment: surgery and distant radiation therapy. But due to multiple character of bone metastases surgery for these metastases is impossible. Within the period of 1999-2004 we studied 310 patients with differentiated TC aged 22-72 (of them 254 women and 56 men). Bone metastases were revealed in 15 (4.8%) patients, of them 13 women and 2 men aged 46-68. As to the stage of the tumor with bone metastases, the patients were grouped as follows: T1 N0 M0 -1 (6.7%), T2-3 N0 M0 -1 (6.7%), TxNxMo-4 (26.7%), T1-4 N0 -1M1-9 (60%) patients. Of the 15 patients with bone metastases, papillary cancer was verified in 5 (33.3%) patients, follicular in 5 (33.3%) papillary cancer follicular variant in 1 (6.7%), medullary in 4 (26.3%). Together with bone metastases, 5 (33.3%) had metastases to the lung parenchyma, diffuse and solitary; 12 (80%) had metastases to

  20. Liver metastases: interventional therapeutic techniques and results, state of the art

    International Nuclear Information System (INIS)

    The liver is the most common site of metastatic tumour deposits. Hepatic metastases are the major cause of morbidity and mortality in patients with gastrointestinal carcinomas and other malignant tumours. The rationale and results for interventional therapeutic techniques in the treatment of liver metastases are presented. For the treatment of patients with irresectable liver metastases, alternative local ablative therapeutic modalities have been developed. Technique and results of local interventional therapies are presented such as microwave-, radiofrequency (RF)- and ultrasound ablation, and laser-induced interstitial therapy (LITT), cryotherapy and local drug administration such as alcohol injection, endotumoral chemotherapy and regional chemoembolisation. In addition to cryotherapy, all ablative techniques can be performed percutaneously with low morbidity and mortality. Cryotherapy is an effective and precise technique for inducing tumour necrosis, but it is currently performed via laparotomy. Percutaneous local alcohol injection results in an inhomogeneous distribution in liver metastases with unreliable control rates. Local chemotherapeutic drug instillation and regional chemoembolisation produces relevant but non-reproducible lesions. Laser-induced interstitial thermotherapy (LITT) performed under MRI guidance results in precise and reproducible areas of induced necrosis with a local control of 94 %, and with an improved survival rate. Interventional therapeutic techniques of liver metastases do result in a remarkable local tumour control rate with improved survival results. (orig.)

    Few clinical studies have demonstrated an anti-proliferative activity of somatostatin (SST) analogs in carcinoids. We report the case of a woman with liver metastases of neuroendocrine tumor and no evidence of the primary tumor. The liver metastases were characterized by high proliferation indes, immunoreactiviy for somatostatin receptor (SSTR) -1,2,3 and 5and positive octreoscan. Urinary 5-hydrozyindolacetic acid, serum serotonin and chromogranin A were elevated. Slow release lanretoide (SR-LAN) therapy for 3 mo controlled clinical and biochemical signs of carcinoid tumor and caused a clear-cut reduction in the diameter of two liver metastases and disappearance of another lesion, with further reduction after 6 and 18 mo. We demonstrated a Clear-cut long-lasting antioccult carcinoid with high proliferation index and immunoreactivity for SSTR-1,2,3, and 5. Immunohistochemistry for SSTRs could be a suitable method for the selection of patients with metasatic carcinoid that may benefit from SST analog therapy.

    BACKGROUND: Uveal melanoma is the most common primary intraocular malignancy in adults. Despite successful control of the primary tumor, metastatic disease will ultimately develop in approximately 50% of patients, with the liver being the most common site for metastases. The median survival for...... patients with liver metastases is between 6 and 12 months, and no treatment has in randomized trials ever been shown to prolong survival. A previous phase II trial using isolated hepatic perfusion (IHP) has suggested a 14-month increase in overall survival compared with a historic control group consisting...... of the longest surviving patients in Sweden during the same time period (26 versus 12 months). METHODS/DESIGN: This is the protocol for a multicenter phase III trial randomizing patients with isolated liver metastases of uveal melanoma to IHP or best alternative care (BAC).

    Standardized added metabolic activity (SAM) is a PET parameter for assessing the total metabolic load of malignant processes, avoiding partial volume effects and lesion segmentation. The potential role of this parameter in the assessment of response to chemotherapy and bevacizumab was tested in patients with metastatic colorectal cancer with potentially resectable liver metastases (mCRC). {sup 18}F-FDG PET/CT was performed in 18 mCRC patients with liver metastases before treatment and after five cycles of FOLFOX/FOLFIRI and bevacizumab. Of the 18 patients, 16 subsequently underwent resection of liver metastases. Baseline and follow-up SUV{sub max}, and SAM as well as reduction in SUV{sub max} ({nabla}SUV{sub max}) and SAM ({nabla}SAM) of all liver metastases were correlated with morphological response, and progression-free and overall survival (PFS and OS). A significant reduction in metabolic activity of the liver metastases was seen after chemotherapy with a median {nabla}SUV{sub max} of 25.3 % and {nabla}SAM of 94.5 % (p = 0.033 and 0.003). Median baseline SUV{sub max} and SAM values were significantly different between morphological responders and nonresponders (3.8 vs. 7.2, p = 0.021; and 34 vs. 211, p = 0.002, respectively), but neither baseline PET parameters nor morphological response was correlated with PFS or OS. Follow-up SUV{sub max} and SAM as well as {nabla}SAM were found to be prognostic factors. The median PFS and OS in the patient group with a high follow-up SUV{sub max} were 10.4 months and 32 months, compared to a median PFS of 14.7 months and a median OS which had not been reached in the group with a low follow-up SUV{sub max} (p = 0.01 and 0.003, respectively). The patient group with a high follow-up SAM and a low {nabla}SAM had a median PFS and OS of 9.4 months and 32 months, whereas the other group had a median PFS of 14.7 months and a median OS which had not been reached (p = 0.002 for both PFS and OS). {sup 18}F-FDG PET imaging is a useful

    Purpose: To present long-term outcomes on the safety and efficacy of Yttrium-90 radioembolization in the treatment of unresectable hepatic neuroendocrine metastases refractory to standard-of-care therapy. Methods and Materials: This study was approved by our institutional review board and was compliant with the Health Insurance Portability and Accountability Act. Forty patients with hepatic neuroendocrine metastases were treated with {sup 90}Y radioembolization at a single center. Toxicity was assessed using National Cancer Institute Common Terminology Criteria v3.0. Response to therapy was assessed by World Health Organization (WHO) guidelines for size and European Association for the Study of the Liver disease (EASL) guidelines for necrosis. Time to response and overall survival were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed. Results: The median dose was 113 Gy (29-299 Gy). Clinical toxicities included fatigue (63%), nausea/vomiting (40%), abdominal pain (18%), fever (8%), diarrhea and weight loss (5%); Grade 3 and 4 bilirubin toxicities were experienced by 2 patients and 1 patient, respectively. Different responses were noted by WHO (complete response, 1.2%; partial response, 62.7%) and EASL (complete response, 20.5%; partial response, 43.4%). Median time to response was 4 and 4.9 months by lesion and patient, respectively. The 1-, 2-, and 3-year overall survival rates were 72.5%, 62.5%, and 45%, respectively. Eastern Cooperative Oncology Group (ECOG) performance score 0 (p < 0.0001), tumor burden {<=}25% (p = 0.0019), albumin {>=}3.5 g/dL (p = 0.017), and bilirubin {<=}1.2 mg/dL (p = 0.002) prognosticated survival on univariate analysis; only ECOG performance score 0 and bilirubin {<=}1.2 mg/dL prognosticated better survival outcome on multivariate analysis (p = 0.0001 and p = 0.02). Conclusion: Yttrium-90 therapy for hepatic neuroendocrine metastases leads to satisfactory tumor response and patient survival

    Objective: To compare different three-dimensional volumetric algorithms (3D-algorithms) and RECIST for size measurement and response assessment in liver metastases from colorectal and pancreatic cancer. Methods: The volumes of a total of 102 liver metastases in 45 patients (pancreatic cancer, n = 22; colon cancer, n = 23) were estimated using three volumetric methods (seeded region growing method, slice-based segmentation, threshold-based segmentation) and the RECIST 1.1 method with volume calculation based on the largest axial diameter. Each measurement was performed three times by one observer. All four methods were applied to follow-up on 55 liver metastases in 29 patients undergoing systemic treatment (median follow-up, 3.5 months; range, 1–10 months). Analysis of variance (ANOVA) with post hoc tests was performed to analyze intraobserver variability and intermethod differences. Results: ANOVA showed significant higher volumes calculated according to the RECIST guideline compared to the other measurement methods (p < 0.001) with relative differences ranging from 0.4% to 41.1%. Intraobserver variability was significantly higher (p < 0.001) for RECIST and threshold based segmentation (3.6–32.8%) compared with slice segmentation (0.4–13.7%) and seeded region growing method (0.6–10.8%). In the follow-up study, the 3D-algorithms and the assessment following RECIST 1.1 showed a discordant classification of treatment response in 10–21% of the patients. Conclusions: This study supports the use of volumetric measurement methods due to significant higher intraobserver reproducibility compared to RECIST. Substantial discrepancies in tumor response classification between RECIST and volumetric methods depending on applied thresholds confirm the requirement of a consensus concerning volumetric criteria for response assessment.

    Lutsenko, I.V. (Nauchno-Issledovatel' skij Onkologicheskij Inst., Moscow (USSR))

    Metastases of thyroid cancer to the chest cavity organs were detected in 19.4%. They were found most frequently in the pulmonary tissue (75.8%), in the mediastinal lymph nodes (57.9%), less frequently in the lymph nodes of the roots of the lungs (30.4%) and very rarely in the pleura (2.6%). X-ray signs of metastases are identical for all histological structures of thyroid cancer. The most typical are multiple lesions (91.8%). The nodular form is found in 74.5%, the nodal form in 17.2.%. Solitary metastases and cancerous lymphangitis are rarely noted (7.2 and 0.9% respectively. The regression of metastases, spontaneous pneumothorax and pneumonia are rarely observed as well (1.8, 0.9 and 1.8%) respectively). The doubling time of the size of metastatic tumors of thyroid cancer ranges from 52 to 379 days. The use of radioactive iodine and hormones inhibits their growth rates.

X-ray signs of metastases are identical for all histological structures of thyroid cancer. The most typical are multiple lesions (91.8%). The nodular form is found in 74.5%, the nodal form in 17.2.%. Solitary metastases and cancerous lymphangitis are rarely noted (7.2 and 0.9% respectively. The regression of metastases, spontaneous pneumothorax and pneumonia are rarely observed as well (1.8, 0.9 and 1.8%) respectively). The doubling time of the size of metastatic tumors of thyroid cancer ranges from 52 to 379 days. The use of radioactive iodine and hormones inhibits their growth rates

  12. Liver metastases of neuroendocrine tumours; early reduction of tumour load to improve life expectancy

    Full Text Available Abstract Background Neuroendocrine tumours frequently metastasize to the liver. Although generally slowly progressing, hepatic metastases are the major cause of carcinoid syndrome and ultimately lead to liver dysfunction, cardiac insufficiency and finally death. Methods A literature review was performed to define the optimal treatment strategy and work-up in patients with neuroendocrine hepatic metastases. Based on this, an algorithm for the management of these patients was established. Results Platelet serotonin and chromogranin A are useful biomarkers for detection and follow-up of neuroendocrine tumour. Helical computed tomography and somatostatin receptor scintigraphy are the most sensitive diagnostic modalities. Surgical debulking is an accepted approach for reducing hormonal symptoms and to establish better conditions for medical treatment, but is frequently impossible due to the extent of disease. A novel approach is the local ablation of tumour by thermal coagulation using therapies such as radiofrequency ablation (RFA or laser induced thermotherapy (LITT. These techniques preserve normal liver tissue. There is a tendency to destroy metastases early in the course of disease, thereby postponing or eliminating the surgically untreatable stage. This can be combined with postoperative radioactive octreotide to eliminate small multiple metastases. In patients with extensive metastases who are not suitable for local destruction, systemic therapy by octreotide, 131I-MIBG treatment or targeted chemo- and radiotherapy should be attempted. A final option for selective patients is orthotopic liver transplantation. Conclusion Treatment for patients with neuroendocrine hepatic metastases must be tailored for each individual patient. When local ablative therapies are used early in the course of the disease, the occurrence of carcinoid syndrome with end stage hepatic disease can be postponed or prevented.

    Background KRAS mutations in colorectal cancer primary tumors predict resistance to anti-Epidermal Growth Factor Receptor (EGFR) monoclonal antibody therapy in patients with metastatic colorectal cancer, and thus represent a true indicator of EGFR pathway activation status. Methodology/Principal Findings KRAS mutations were retrospectively studied using polymerase chain reactions and subsequent sequencing of codons 12 and 13 (exon 2) in 110 patients with metastatic colorectal tumors. These studies were performed using tissue samples from both the primary tumor and their related metastases (93 liver, 84%; 17 lung, 16%). All patients received adjuvant 5-Fluorouracil-based polychemotherapy after resection of metastases. None received anti-EGFR therapy. Mutations in KRAS were observed in 37 (34%) of primary tumors and in 40 (36%) of related metastases, yielding a 94% level of concordance (kappa index 0.86). Patients with primary tumors possessing KRAS mutations had a shorter disease-free survival period after metastasis resection (12.0 vs 18.0 months; P = 0.035) than those who did not. A higher percentage of KRAS mutations was detected in primary tumors of patiens with lung metastases than in patients with liver metastases (59% vs 32%; p = 0.054). To further evaluate this finding we analyzed 120 additional patients with unresectable metastatic colorectal cancer who previously had their primary tumors evaluated for KRAS mutational status for clinical purposes. Separately, the analysis of these 120 patients showed a tendency towards a higher degree of KRAS mutations in primary tumors of patients with lung metastases, although it did not reach statistical significance. Taken together the group of 230 patients showed that KRAS was mutated significantly more often in the primary tumors of patients with lung metastases (57% vs 35%; P = 0.006). Conclusions/Significance Our results suggest a role for KRAS mutations in the propensity of primary colorectal tumors to

  16. Image-Guided Robotic Stereotactic Body Radiation Therapy for Liver Metastases: Is There a Dose Response Relationship?

    International Nuclear Information System (INIS)

    Purpose: To evaluate the outcome, tolerance, and toxicity of stereotactic body radiotherapy, using image-guided robotic radiation delivery, for the treatment of patients with unresectable liver metastases. Methods and Material: Patients were treated with real-time respiratory tracking between July 2007 and April 2009. Their records were retrospectively reviewed. Metastases from colorectal carcinoma and other primaries were not necessarily confined to liver. Toxicity was evaluated using National Cancer Institute Common Criteria for Adverse Events version 3.0. Results: Forty-two patients with 62 metastases were treated with two dose levels of 40 Gy in four Dose per Fraction (23) and 45 Gy in three Dose per Fraction (13). Median follow-up was 14.3 months (range, 3-23 months). Actuarial local control for 1 and 2 years was 90% and 86%, respectively. At last follow-up, 41 (66%) complete responses and eight (13%) partial responses were observed. Five lesions were stable. Nine lesions (13%) were locally progressed. Overall survival was 94% at 1 year and 48% at 2 years. The most common toxicity was Grade 1 or 2 nausea. One patient experienced Grade 3 epidermitis. The dose level did not significantly contribute to the outcome, toxicity, or survival. Conclusion: Image-guided robotic stereotactic body radiation therapy is feasible, safe, and effective, with encouraging local control. It provides a strong alternative for patients who cannot undergo surgery.

  17. PET/CT in lung cancer with brain metastases

    International Nuclear Information System (INIS)

    PET/CT is a method for diagnosis, staging and evaluating the effect of lung cancer treatment. The lung cancer is one of the cancers with most frequent localization of the metastases in brain. We have studied with 18 FDG-PET/CT 45 patients, 26 male (57.8%) and 19 female (42.2%) between 41 to 71 years of age, diagnosed with non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC) and brain metastases by 63 examinations. Examinations have been executed on integrated apparatus Phillips Gemini TF (2009). 18FDG has been applied by i.v. injection with activity 0.14 mCi/kg. Patients are staged by TNM classification. Survival has been evaluated by Kaplan-Meier method, for comparison of studied groups the log rank (Mantel-Cox) has been applied. (P<0.05). Multiple metastases in brain have been detected in 8 patients (17%). Hypo-metabolic have been found in 7 patients (14.9%), with hyper-metabolic - 10 (21.3%), with ring-like -7 (14.9%). In patients with metastases operated on, in the area of the operative intervention a hypo-metabolic zone has been found. New metastases have been found in 3 patients after operation. The median of survival of the patients with NSCLC in months for stage II and III has been estimated to 25.2 months and for stage IV to 12.9 months and total survival to 16.8 months (P=0.03). The median of survival in months for patients with NSCLC and SCLC in II and III stage is estimated to 28.4 months, for stage IV is estimated to 12.4 months and total survival is estimated to 16.8 months (P=0.04). Survival of the patients with NSCLC and SCLC with brain metastases is significantly dependent on the clinical stage. The median of survival in patients to III stage is double times longer than the median of survival of patients in IV stage. The median of total survival is estimated to 16.8 months. Most common histological form of the lung cancer in case of metastases in brain is adenocarcinoma. The established by PET/CT lesions in asymptomatic patients

    Bone metastasis is a common and debilitating consequence of lung cancer: 30%-40% of patients with non-small cell lung cancer develop bone metastases during the course of their disease. Lung cancer cells find a favorable soil in the bone microenvironment due to factors released by the bone matrix, the immune system cells, and the same cancer cells. Many aspects of the cross-talk among lung tumor cells, the immune system, and bone cells are not clear, but this review aims to summarize the recen...

  19. Radiotherapy for brain metastases of the breast cancer

    International Nuclear Information System (INIS)

    Twenty-two patients with brain metastases of breast cancer treated by irradiation between 1974 and 1983 were reviewed. Significant neurologic improvement was obtained in 80 %. The median duration of symptomatic palliation caused by irradiation and the median survival from the diagnosis of brain metastases were 3.0 months and 5.0 months, respectively. As a favorable prognosis can be expected for patients showing good performance, minor neurologic disorders, a long latent period between the first treatment of the primary lesion and the onset of the brain metastasis, and without extracranial metastases, irradiation with more than 40 Gy is recommended. Sequential CT examinations were useful to judge the effectiveness of treatment. (author)

    2009-04-01

    Full Text Available Abstract Background Prognostic scores might be useful tools both in clinical practice and clinical trials, where they can be used as stratification parameter. The available scores for patients with brain metastases have never been tested specifically in patients with primary breast cancer. It is therefore unknown which score is most appropriate for these patients. Methods Five previously published prognostic scores were evaluated in a group of 83 patients with brain metastases from breast cancer. All patients had been treated with whole-brain radiotherapy with or without radiosurgery or surgical resection. In addition, it was tested whether the parameters that form the basis of these scores actually have a prognostic impact in this biologically distinct group of brain metastases patients. Results The scores that performed best were the recursive partitioning analysis (RPA classes and the score index for radiosurgery (SIR. However, disagreement between the parameters that form the basis of these scores and those that determine survival in the present group of patients and many reported data from the literature on brain metastases from breast cancer was found. With the four statistically significant prognostic factors identified here, a 3-tiered score can be created that performs slightly better than RPA and SIR. In addition, a 4-tiered score is also possible, which performs better than the three previous 4-tiered scores, incl. graded prognostic assessment (GPA score and basic score for brain metastases (BSBM. Conclusion A variety of prognostic models describe the survival of patients with brain metastases from breast cancer to a more or less satisfactory degree. However, the standard brain metastases scores might not fully appreciate the unique biology and time course of this disease, e.g., compared to lung cancer. It appears possible that inclusion of emerging prognostic factors will improve the results and allow for development and validation

    Full Text Available Abstract Background Little is known about the clinical features and prognostic factors of bone metastases of hepatocellular carcinoma (HCC following liver transplantation (LT. Methods All adult patients undergoing LT from 2001 to 2010 were reviewed. Patients with HCC bone metastases after LT received external beam radiotherapy(EBRT during this period. Demographic variables, laboratory values, and tumor characteristics were determined before LT and EBRT. Total radiation dose ranged from 8 to 60 Gy(median dose 40.0 Gy. Results The trunk was the most common site of bone metastases with finding of expansile soft-tissue masses in 23.3% of patients. Overall pain relief from EBRT occurred in 96.7% (29/30. No consistent dose-response relationship was found for palliation of with doses between 30 and 56 Gy (P = 0.670. The median survivals from the time of bone metastases was 8.6 months. On univariate and multivariate analyses, better survival was significantly associated with a better Karnofsky performance status (KPS and well-controlled intrahepatic tumor, but not with lower alpha-fetoprotein levels. The median time from LT to bone metastases was 7.1 months. Patients exceeding the Shanghai criteria presented with bone metastases earlier than those within the Fudan criteria. Patients with soft-tissue extension always had later bone metastases. The majority of deaths were caused by liver failure due to hepatic decompensation or tumor progression. Conclusion The prognostic factors of bone metastases of HCC following LT are KPS and well-controlled intrahepatic. Even though survival is shorter for these patients, EBRT provides effective palliation of pain.

    Lymph node status is a key prognostic factor in penile squamous cell carcinoma.Recently,growing evidence indicates a multimodality approach consisting of neoadjuvant chemotherapy followed by consolidation surgery improves the outcome of locally advanced penile cancer.Thus,accurate estimation of survival probability in node-positive penile cancer is critical for treatment decision making,counseling of patients and follow-up scheduling.This article reviewed evolving developments in assessing the risk for cancer progression based on lymph node related variables,such as the number of metastatic lymph nodes,bilateral lymph node metastases,the ratio of positive lymph nodes,extracapsular extension of metastatic lymph nodes,pelvic lymph node metastases,metastatic deposit in sentinel lymph nodes and N stage in TNM classification.Controversial issues surrounding the prognostic value of these nodal related predictors were also discussed.

  4. CT images in brain metastases of the primary lung cancer

    International Nuclear Information System (INIS)

    Computed tomography (CT) of the brain was carried out in 366 patients with lung cancer in order to evaluate brain metastases. Suggestive evidences of metastases such as low density or contrast enhancement were observed in 65 cases (18%), although 26% of the metastatic cases revealed no signs or symptoms of neurological disorders. These facts emphasize that brain CT should be conducted in all patients with lung cancer, irrespective of signs and symptoms. A solitary lesion was noted in 37 out of 65 metastatic cases. More than 80% of the metastatic lesions were demonstrated as iso-density on plain CT films and were enhanced by intravenous injection of contrast medium. Although CT images of metastatic lesions reveal certain characteristic appearances according to the histologic type of the primary cancer, perifocal low density and central cavitation were observed independent of histologic type.

    We report a case of small cell esophageal carcinoma (SCEC) with multiple liver metastases treated with some success by chemotherapy with irinotecan (CPT-11) plus cisplatin (CDDP). Radiologic and endoscopic examination of a 75-year-old man with multiple liver tumors disclosed a 4.0-cm type 2 tumor in the middle third of the esophagus. An endoscopically obtained biopsy specimen was diagnosed as undifferentiated small cell carcinoma. Multiple liver metastases were confirmed but lymph node metastases and distant metastases other than those in the liver were not detected. After six courses of chemotherapy with CPT-11 plus CDDP, the primary lesion showed complete response and liver metastases showed partial response. However, because all lesions almost immediately relapsed or progressed, arterial infusion chemotherapy for liver metastases and radiation for the primary lesion were given as second-line treatment. The primary lesion showed complete response with radiation. Arterial infusion chemotherapy prevented the progression of liver metastases once, but the patient died of liver failure at last. No distant lesions including metastatic lymph nodes were confirmed over the course of his illness, and the patient survived for a year after first diagnosis. Although the prognosis of SCEC is quite unfavorable due to highly aggressive behavior, a better prognosis is possible with effective chemotherapy and second-line treatment is important in improving prognosis.

    The aim of this study was to determine trends in incidence, treatment and survival of colorectal cancer (CRC) patients with synchronous metastases (Stage IV) in the Netherlands. This nationwide population-based study included 160,278 patients diagnosed with CRC between 1996 and 2011. We evaluated changes in stage distribution, location of synchronous metastases and treatment in four consecutive periods, using Chi square tests for trend. Median survival in months was determined, using Kaplan-Meier analysis. The proportion of Stage IV CRC patients (n = 33,421) increased from 19 % (1996-1999) to 23 % (2008-2011, p < 0.001). This was predominantly due to a major increase in the incidence of lung metastases (1.7-5.0 % of all CRC patients). During the study period, the primary tumor was resected less often in Stage IV patients (65-46 %) and the use of systemic treatment has increased (29-60 %). Also an increase in metastasectomy was found in patients with one metastatic site, especially in patients with liver-only disease (5-18 %, p < 0.001). Median survival of all Stage IV CRC patients increased from 7 to 12 months. Especially in patients with metastases confined to the liver or lungs this improvement in survival was apparent (9-16 and 12-24 months respectively, both p < 0.001). In the last two decades, more lung metastases were detected and an increasing proportion of Stage IV CRC patients was treated with systemic therapy and/or metastasectomy. Survival of patients has significantly improved. However, the prognosis of Stage IV patients becomes increasingly diverse. PMID:25899064

    Orbital metastases from breast cancer (BC) are rare, but often debilitating. BC accounts for nearly half of metastases to the orbit. Orbital metastases may be discovered years after the initial diagnosis of BC, and are rare at initial presentation. A search of the institutional data base at an academic cancer center identified BC patients who developed or presented with orbital metastases from 2000 to 2013. Baseline characteristics, treatment modalities, survival and treatment responses were collected from the electronic medical record. There were 20 patients identified with orbital metastases (0.7% of all BC cases). The median age at diagnosis of BC was 49 years; 80% had estrogen positive disease. The interval between the initial diagnosis of BC and the presentation of orbital metastases was 8.5 years (0-19 years). Orbital disease was the initial presentation of BC in two cases. Three patients developed bilateral orbital metastases and seven had accompanying brain metastases. The most common presentation was decreased vision (55%), followed by diplopia (25%). The median survival after orbital metastases was 24 months. Thirteen patients (65%) received local radiation therapy. Of those radiated, 90% reported improvement of orbital symptoms. Other treatments included intraocular bevacizumab, surgery, and systemic therapy. Orbital metastases tend to occur in estrogen receptor positive disease and are often found years after BC onset. Orbital metastases may be associated with the development of brain metastases. Radiotherapy is the preferred local therapy and had high symptom control in this cohort. Oncologists should be aware of the signs of orbital metastases and the treatment options. PMID:27143519

  10. Oral contraceptives and liver cancer.

    Science.gov (United States)

    1997-11-01

    To date, nine case-control studies conducted in developed countries have identified an association between oral contraceptives (OCs) and liver cancer. The most recent population-based data from both developed and developing countries failed to confirm such an association, however. A study conducted by the World Health Organization in eight developing countries (Chile, China, Colombia, Israel, Kenya, Nigeria, Philippines, and Thailand), in which 122 women with liver cancer were matched with 802 controls, found no elevated risk for OC users compared with never-users (relative risk, 0.7; 95% confidence interval, 0.4-1.2). This study is particularly significant since it was conducted in countries where hepatitis B virus infection, an important risk factor for primary liver cancer, is widespread. In addition, population mortality data from the US, UK, Japan, and Sweden have failed to document increases in liver cancer cases coincident with increases in OC use. Given that population statistics can detect changes on the magnitude of a 40-50% decrease in the risk of ovarian and endometrial cancer related to OC use, they should be able to detect increases of two to 20 times the risk of liver cancer. The increased risk of liver cancer found in the case-control studies may reflect bias resulting from the small size of these studies. PMID:12348250

    Clinical management of breast cancer is increasingly personalized and based on molecular profiling. Often, primary tumors are used as proxies for systemic disease at the time of recurrence. However, recent studies have revealed substantial discordances between primary tumors and metastases, both with respect to traditional clinical treatment targets and on the genomic and transcriptomic level. With the increasing use of molecularly targeted therapy, discordance of actionable molecular targets between primary tumors and recurrences can result in nonoptimal treatment or unnecessary side effects. The purpose of this review is to illuminate the extent of cancer genome evolution through disease progression and the degree of molecular concordance between primary breast cancers and matched metastases. We present an overview of the most prominent studies investigating the expression of endocrine receptors, transcriptomics, and genome aberrations in primary tumors and metastases. In conclusion, biopsy of metastatic lesions at recurrence of breast cancer is encouraged to provide optimal treatment of the disease. Furthermore, molecular profiling of metastatic tissue provides invaluable mechanistic insight into the biology underlying metastatic progression and has the potential to identify novel, potentially druggable, drivers of progression.

    The application of gene transfer technologies to the treatment of cancer has led to the development of new experimental approaches like gene directed enzyme/prodrug therapy (GDEPT), inhibition of oncogenes and restoration of tumor-suppressor genes. In addition,gene therapy has a big impact on other fields like cancer immunotherapy, anti-angiogenic therapy and virotherapy.These strategies are being evaluated for the treatment of primary and metastatic liver cancer and some of them have reached clinical phases. We present a review on the basis and the actual status of gene therapy approaches applied to liver cancer.

    Purpose: We previously developed a multigene expression model of tumor radiation sensitivity index (RSI) with clinical validation in multiple independent cohorts (breast, rectal, esophageal, and head and neck patients). The purpose of this study was to assess differences between RSI scores in primary colon cancer and metastases. Methods and Materials: Patients were identified from our institutional review board–approved prospective observational protocol. A total of 704 metastatic and 1362 primary lesions were obtained from a de-identified metadata pool. RSI was calculated using the previously published rank-based algorithm. An independent cohort of 29 lung or liver colon metastases treated with 60 Gy in 5 fractions stereotactic body radiation therapy (SBRT) was used for validation. Results: The most common sites of metastases included liver (n=374; 53%), lung (n=116; 17%), and lymph nodes (n=40; 6%). Sixty percent of metastatic tumors, compared with 54% of primaries, were in the RSI radiation-resistant peak, suggesting metastatic tumors may be slightly more radiation resistant than primaries (P=.01). In contrast, when we analyzed metastases based on anatomical site, we uncovered large differences in RSI. The median RSIs for metastases in descending order of radiation resistance were ovary (0.48), abdomen (0.47), liver (0.43), brain (0.42), lung (0.32), and lymph nodes (0.31) (P<.0001). These findings were confirmed when the analysis was restricted to lesions from the same patient (n=139). In our independent cohort of treated lung and liver metastases, lung metastases had an improved local control rate compared to that in patients with liver metastases (2-year local control rate of 100% vs 73.0%, respectively; P=.026). Conclusions: Assessment of radiation sensitivity between primary and metastatic tissues of colon cancer histology revealed significant differences based on anatomical location of metastases. These initial results warrant validation in a larger

Results: The most common sites of metastases included liver (n=374; 53%), lung (n=116; 17%), and lymph nodes (n=40; 6%). Sixty percent of metastatic tumors, compared with 54% of primaries, were in the RSI radiation-resistant peak, suggesting metastatic tumors may be slightly more radiation resistant than primaries (P=.01). In contrast, when we analyzed metastases based on anatomical site, we uncovered large differences in RSI. The median RSIs for metastases in descending order of radiation resistance were ovary (0.48), abdomen (0.47), liver (0.43), brain (0.42), lung (0.32), and lymph nodes (0.31) (P<.0001). These findings were confirmed when the analysis was restricted to lesions from the same patient (n=139). In our independent cohort of treated lung and liver metastases, lung metastases had an improved local control rate compared to that in patients with liver metastases (2-year local control rate of 100% vs 73.0%, respectively; P=.026). Conclusions: Assessment of radiation sensitivity between primary and metastatic tissues of colon cancer histology revealed significant differences based on anatomical location of metastases. These initial results warrant validation in a larger

  16. Biodistribution of Boron compounds in an experimental model of liver metastases for Boron Neutron Capture (BNCT) Studies

    International Nuclear Information System (INIS)

    Boron Neutron Capture Therapy (BNCT) is a binary treatment modality that involves the selective accumulation of 10B carriers in tumors followed by irradiation with thermal or epithermal neutrons. The high linear energy transfer alpha particles and recoiling 7Li nuclei emitted during the capture of a thermal neutron by a 10B nucleus have a short range and a high biological effectiveness. Thus, BNCT would potentially target neoplastic tissue selectively. In previous studies we demonstrated the therapeutic efficacy of different BNCT protocols in an experimental model of oral cancer. More recently we performed experimental studies in normal rat liver that evidenced the feasibility of treating liver metastases employing a novel BNCT protocol proposed by JEC based on ex-situ treatment and partial liver auto-transplant. The aim of the present study was to perform biodistribution studies with different boron compounds and different administration protocols to determine the protocols that would be therapeutically useful in 'in vivo' BNCT studies at the RA-3 Nuclear Reactor in an experimental model of liver metastases in rats. Materials and Methods. A total of 70 BDIX rats (Charles River Lab., MA, USA) were inoculated in the liver with syngeneic colon cancer cells DH/DK12/TRb (ECACC, UK) to induce the development of subcapsular metastatic nodules. 15 days post-inoculation the animals were used for biodistribution studies. A total of 11 protocols were evaluated employing the boron compounds boronophenylalanine (BPA) and GB-10 (Na210B1-0H10), alone or combined employing different doses and administration routes. Tumor, normal tissue and blood samples were processed for boron measurement by ICP-OES. Results. Several protocols proved potentially useful for BNCT studies in terms of absolute boron concentration in tumor and preferential uptake of boron by tumor tissue, i.e. BPA 15.5 mg 10B/kg iv + GB-10 50 mg 10B/kg iv; BPA 46.5 mg 10B/kg ip; BPA 46.5 mg 10B/kg ip + iv; BPA 46

  17. Liver scanning in the diagnosis of metastases from malignant tumors of the gastrointestinal tract

    International Nuclear Information System (INIS)

    The National Institute of Oncology and Radiobiology (INOR) established a line of clinical investigation in January, 1974, which was later added to clinical care. This line consisted of trying to arrive at a preoperative diagnosis - by means of liver scanning - of the potential liver metastases of primitive tumors in the gastrointestinal tract. Metastable 113Indium was used. A review of the results obtained in the 50 patients included in the investigation program is made. The results of preoperative scanning were compared with operative findings. Twelve liver metastases (24%) were found. In 40 patients there was agreement (80%) between preoperative scanning and operatory findings. At present, ultrasound is a necessary supplement to scans, which supplements it but does not exclude it. The tracer element used now is technetium-99 M coloidal sulphide

    2016-06-01

    Occurring either synchronously or metachronously to the primary tumor, peritoneal metastases (PM) are diagnosed in 8 to 20 % of the patients with colorectal cancer (CRC). Prognosis of these patients appears to be worse than those with other sites of metastases. While systemic therapy has shown significant prolongation of survival in patients with stage IV colorectal cancer, the outcomes in the subset of patients with PM has been much inferior. Over the last 2 decades, cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) have been effective in substantially prolonging survival in patients with colorectal PM and have the potential to cure certain patients as well. This article reviews the current evidence for CRS and HIPEC to treat colorectal PM as well as future research going on in this form of locoregional treatment. PMID:27065708

    Full Text Available Lung cancer is mostly common occurring oncological disease in the developed countries. Currently lung cancers are subdivided into nonsmall-cell (adenocarcinoma, large-cell, squamous cell and small-cell. The difference in the clinical and morphological picture leads to the necessity of choosing therapeutic approaches to patients of various groups.Lung cancer should be referred to encephalotropic diseases since metastatic lesion of the central nervous system is sufficiently common complication. Successes of complex treatment of primary tumor result in increase of total longlivety currently ther is ageing of patients suffering lung cancer. These factors increase the risk of metastatic lesions of the brain.Interest to the problem of neurosurgical treatment of patients suffering lung cancer is determined by frequency of lesion, varicosity of morphological variants of the disease, requiring various algorithms of treatment and diagnosis.The main role of neurosurgical intervention in cerebral metastases of lung cancer consist in creation of the paled of carrying out combined therapy. Ideally, a neurosurgical operation should be carried out with clearcut observance of oncological principles of ablasty.Adequate comprehensive approach to treatment or patients with cerebral metastases of various forms of lung cancer with the developed of optimal tactics of and stages of treatment would make it possible to increase duration and quality of life of patients.

  20. Treatment of brain metastases from primary lung cancer

    International Nuclear Information System (INIS)

    Purpose: A retrospective study of patients treated at the Peter MacCallum Cancer Institute for brain metastases from primary carcinoma of the lung is presented. Methods and Materials: The medical records of 416 patients with the diagnosis of primary carcinoma of the lung who presented with, or subsequently developed, brain metastases during the period January 1984 to December 1987 were reviewed. Information on a number of factors of potential prognostic significance (sex, age, histology, performance status and interval between diagnosis of the primary and brain metastases) was collected. Details of surgery, radiation and steroid usage were recorded, and any steroid side effects documented. Survival was calculated from the date of diagnosis of brain metastases. Stepwise regression based on Cox's proportional hazards model was used to determine significant prognostic factors affecting survival. Patients with and without steroid side effects were compared using Yate's corrected chi-square test. Results: The overall estimated median survival was only 3.3 months (95% confidence interval 2.9-3.7 months). Only two factors were found to be associated with a significantly improved survival--surgical intervention and good performance status. After taking these two factors into account, the dose of radiation used (< 30 Gy or ≥ 30 Gy) did not influence survival. There was a 3% incidence of gastric bleeding or perforation in patients taking steroids, with a 40% fatality rate. Predisposing factors to gastric side effects were a prior history of peptic ulcer and/or aspirin or nonsteroidal anti-inflammatory drug consumption. Conclusion: Radiation of brain metastases from primary lung cancer results in modest survival benefit. Radiation dose (< 30 Gy or ≥ 30 Gy) is not a significant determinant of survival. Other treatment modifications, such as concurrent radiation and chemotherapy, should be explored. Steroids should be used with caution as fatal side effects can occur

    Full Text Available MH Wong, N PavlakisDepartment of Medical Oncology, Royal North Shore Hospital, Sydney, NSW, AustraliaAbstract: Bone metastasis in breast cancer is a significant clinical problem. It not only indicates incurable disease with a guarded prognosis, but is also associated with skeletal-related morbidities including bone pain, pathological fractures, spinal cord compression, and hypercalcemia. In recent years, the mechanism of bone metastasis has been further elucidated. Bone metastasis involves a vicious cycle of close interaction between the tumor and the bone microenvironment. In patients with bone metastases, the goal of management is to prevent further skeletal-related events, manage complications, reduce bone pain, and improve quality of life. Bisphosphonates are a proven therapy for the above indications. Recently, a drug of a different class, the RANK ligand antibody, denosumab, has been shown to reduce skeletal-related events more than the bisphosphonate, zoledronic acid. Other strategies of clinical value may include surgery, radiotherapy, radiopharmaceuticals, and, of course, effective systemic therapy. In early breast cancer, bisphosphonates may have an antitumor effect and prevent both bone and non-bone metastases. Whilst two important Phase III trials with conflicting results have led to controversy in this topic, final results from these and other key Phase III trials must still be awaited before a firm conclusion can be drawn about the use of bisphosphonates in this setting. Advances in bone markers, predictive biomarkers, multi-imaging modalities, and the introduction of novel agents have ushered in a new era of proactive management for bone metastases in breast cancer.Keywords: breast cancer, bone metastases, bisphosphonates, denosumab, biomarkers, optimal management

    The management of patients with brain metastases from breast cancer continues to be a major clinical challenge. The standard initial therapeutic approach depends upon the size, location, and number of metastatic lesions and includes consideration of surgical resection, whole-brain radiotherapy, and stereotactic radiosurgery. As systemic therapies for control of extracranial disease improve, patients are surviving long enough to experience subsequent progression events in the brain. Therefore,...

    Brain metastases are frequently encountered in patients with non-small cell lung cancer (NSCLC) and are a significant cause of morbidity and mortality. Antiangiogenesis therapy plays a major role in the management of brain metastases in lung cancer. Bevacizumab have become the novel method for the treatment of lung cancer with brain metastases beyond the whole brain radiation therapy, stereotactic radiosurgery and chemotherapy. Recently, more and more studies and trials laid emphasis on the bevacizumab for NSCLC with brain metastases treatment. The key point is the efficacy and safety. In this review, bevacizumab therapy of NSCLC with brain metastases were summarized. PMID:27561800

    Clinicians generally suspect pulmonary tumor embolism (PTE) with uncontrolled carcinomas which often spread to lungs. We, however, experienced an autopsy case of diffuse microscopic PTE despite controlled liver metastases of transitional cell carcinoma (TCC). A 66-year-old man with progressing respiratory symptoms showed almost normal chest findings on computed tomography. Although liver metastases were successfully shrunk by chemotherapy, the patient died from aggressive respiratory failure. An autopsy revealed small pulmonary vessels showing diffuse tumor emboli. TCC can cause PTE even if liver metastases are controlled. We must therefore be aware that PTE can manifest as respiratory symptoms without any computed tomography findings. PMID:27580549

    Full Text Available Background. The worldwide increasing incidence of thyroid cancer (TC is mainly due to a rise in its major form of differentiated TC (DTC: papillary. Most patients with DTC have a good prognosis; 10-year survival overall rates are as high as 85 %, but not greater than 40 % in a group of patients with distant metastases. At the same time, the lung is the most frequent target for distant metastases, accounting for 70 % of all sites.Objective: to estimate and compare the capabilities of different diagnostic techniques to detect lung metastases of DTC. Materials and methods. The results of diagnosing lung metastases were retrospectively analyzed in 36 patients (33 women and 3 men; mean age 53 years with DTC (29 patients with papillary TC and 7 with follicular TC treated at the department of radiotherapy with systemic therapy, Chelyabinsk Regional Clinical Oncology Center from 2011 to 2014.Results. Chest X-ray could reveal pulmonary metastases in 13 (36 % patients; lung pathology foci were absent in 23 (64 % patients. 131I whole-body scintigraphy (WBS proved to be of informative value in 24 (66.7 % patients, it displayed no increased accumulation of the radiopharmaceutical in the lung of 12 (33.3 % cases.

    Background Metastatic colorectal cancer liver metastases Outcomes after RadioEmbolization (MORE) was an investigator-initiated case-control study to assess the experience of 11 US centers who treated liver-dominant metastases from colorectal cancer (mCRC) using radioembolization [selective internal radiation therapy (SIRT)] with yttrium-90-(90Y)-labeled resin microspheres. Methods Data from 606 consecutive patients who received radioembolization between July 2002 and December 2011 were collected by an independent research organization. Adverse events (AEs) and survival were compared across lines of treatment using Fisher’s exact test and Kaplan-Meier estimates, respectively. Results Patients received a median of 2 (range, 0-6) lines of prior chemotherapy; 35.1% had limited extrahepatic metastases. Median tumor-to-liver ratio and -activity administered at first procedure were 15% and 1.17 GBq, respectively. Hospital stay was 0.05). Median survivals [95% confidence interval (CI)] following radioembolization as a 2nd-line, 3rd-line, or 4th-plus line were 13.0 (range, 10.5-14.6), 9.0 (range, 7.8-11.0), and 8.1 (range, 6.4-9.3) months, respectively; and significantly prolonged in patients with ECOG 0 vs. ≥1 (P=0.009). Statistically significant independent variables for survival at radioembolization were: disease stage [extrahepatic metastases, extent of liver involvement (tumor-to-treated-liver ratio)], liver function (uncontrolled ascites, albumin, alkaline phosphatase, aspartate transaminase), leukocytes, and prior chemotherapy. Conclusions Radioembolization appears to have a favorable risk/benefit profile, even among mCRC patients who had received ≥3 prior lines of chemotherapy. PMID:25830033

    The prognosis of patients with colorectal liver metastases (CRLM) remains low despite advances in chemotherapy and surgery. The expression of h-prune (human homolog of Drosophila prune protein; HGNC13420), an exopolyphosphatase, is correlated with progression and aggressiveness in several cancers and promotes migration and invasion. We investigated the role of h-prune in CRLM. To investigate the role of h-prune, immunohistochemical analysis for h-prune was performed in 87 surgically resected specimens of CRLM obtained between 2001 and 2009 at the Hiroshima University Hospital. Immunohistochemical analysis revealed positive staining for h-prune in 24 (28%) cases. The overall survival rate was significantly lower in h-prune-positive cases than in h-prune-negative cases (p = 0.003). Multivariate analysis showed that h-prune positivity was the only independent factor related to poor overall survival of patients after curative hepatectomy of CRLM. In vitro and in vivo, h-prune-knocked-down and h-prune-overexpressing cells were analyzed. In vitro, h-prune was associated with increased cell motility and upregulation of epithelial-mesenchymal transition (EMT) markers. In a mouse model, h-prune was associated with invasion of the tumor and distant metastases. In summary, h-prune expression is a useful marker to identify high-risk patients for resectable colorectal liver metastasis. h-Prune expression is necessary for cancer cell motility and EMT and is associated with liver and lung metastasis in colorectal cancer cells. h-Prune could be a new prognostic marker and molecular target for CRLM.

    @@ The majority of men with advanced prostate cancer develop bone metastases as opposed to metastases at other sites.1 It has been unclear why prostate cancer selectively metastasizes to and proliferates in bone.Recently, Shiozawa et al.Delineated a mechanism that may account for the establishment of prostate cancer in bone.2 Specifically, they identified that prostate cancer cells compete with hematopoietic stem cells (HSC) for the osteoblast in the HSC niche of the bone.Defining the mechanisms through which prostate cancer cells establish themselves in bone is critical towards developing effective therapeutic strategies to prevent or target bone metastases.

    Full Text Available Abstract Backround Sigmoid colon cancer metachronous metastases commonly occur in the liver and lungs with sporadic reports also to the spleen, stomach, thyroid gland, abdominal wall and upper urinary tract. This is a rare case of metachronous metastases invading the mesorectum and the abdominal wall. Case presentation A 72-year-old female underwent sigmoidectomy for stage I (T2N0 M0 sigmoid colon cancer in May 2008. In June 2009, an abdominal computed tomography scan revealed a tumor 2 cm in size at the lower anterior mesorectum and a second mass 2 cm in size at the anterior abdominal wall midline. Total colonoscopy showed no mucosal lesion. The serum carcinoembryonic antigen level was normal. A biopsy of the mesorectum tumor showed similar histologic characteristics with the primary tumor. Since no other site of recurrence was identified, an abdominoperineal resection was attempted. During the operation and after the removal of the incision recurrence, sinus bradycardia and signs of myocardial ischemia were noticed. A loop transverse colostomy was immediately perfomed and the operation was terminated. Postoperative cardiologic examination revealed an acute myocardium infract. Chemo-radiation of the mesorectum tumor and re-evaluation for surgical excision was decided. Conclusion Metachronous metastasis of the mesorectum from sigmoid colon cancer is extremely rare. Although patterns of lymphatic spread from rectal cancer to sigmoid colon have recently been demonstrated, there is no evidence of metachronous mesorectum invasion from sigmoid colon cancer. This could be the issue for future trials.

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy of continuous hepatic arterial infusion chemotherapy to nonresectable liver metastases from colorectal carcinoma. Methods: Sixty-two patients with nonresectable liver metastases from colorectal carcinoma had been treated with radical operation, and the patients were divided into 2 groups. (1) Group A: 32 patients received continuous hepatic arterial infusion of 5-Fluorouracil (5-Fu)/Calcium Folinate (CF) and dexamethasone via drug delivery system (DDS) implanted percutaneously for 5 days every month. (2) Group B: 30 patients were treated through one bolus arterial infusion of 5-Fu-CF each month. Results: The response rate (CR + PR) of group A and B was 50.0% and 23.3%, respectively (P < 0.05); the survival rate for 1 and 2 years in group A was 65.6% and 39.3%, respectively, but that in group B was 36.7% and 11.5%, respectively (P < 0.05); the toxic reaction at liver, biliary, and gastrointestinal tract in group A was significantly lower than that in group B. Conclusion: Continuous hepatic arterial infusion of 5-Fu/CF and dexamethasone via DDS can prolong the survival rate and improve quality of life in patients with nonresectable liver metastases from colorectal carcinoma

    Neuroendocrine carcinomas (NECs) are rare malignancies that originate from the hormone-producing cells of the body's neuroendocrine system. Rectal high grade NEC (HG-NEC) constituting less than 1% of colorectal cancers can cause large ovarian metastasis that may be the initial presenting complaint. Ovarian Krukenberg tumor from a primary rectal HG-NEC is a very unusual and exceedingly uncommon differential diagnosis for secondary ovarian malignancy. This case report describes one such extremely rare case of a woman who had presented to the gynecology department with features suggestive of ovarian malignancy and was ultimately diagnosed to have Krukenberg tumor originating from neuroendocrine cancer of rectum. We felt this is a good opportunity to spread more light on neuroendocrine neoplasms that are very rare in gynecological practice. PMID:27293931

    VIPoma is a rare neuroendocrine tumor (NET) with a high potential to develop hepatic metastases and poor prognosis. The primitive tumor is nonsymptomatic and usually localized within the pancreas. Liver metastasis drives the prognosis and induces profuse watery diarrhea or renal failure. We herein present severe renal failure or diarrhea in two patients hospitalized in intensive care justifying emergency treatment of liver metastasis. The two patients experienced severe diarrhea due to a hypersecretion of vasoactive intestinal peptide (VIP) from liver metastasis released into the blood circulation. Therapeutic management was discussed and liver transarterial chemoembolization (TACE) was performed with chemotherapy-loaded embospheres, which cause necrosis of tumor lesions. TACE controlled the hormonal syndrome and made patients eligible for curative surgery. Tumor necrosis occurred and VIP levels collapsed. Surgery was performed in one of the two cases after TACE and the patient was considered in remission. Both patients were still alive after 3 years of follow up. Thus, TACE is feasible and appears to be an effective emergency treatment in patients with a VIP-hormonal syndrome due to liver metastases. Despite the biological disorder due to the hormonal secretion, an aggressive approach is warranted in VIP liver metastasis. PMID:27583030

  20. Thyroid metastases in renal cell cancer: two case reports

    International Nuclear Information System (INIS)

    Non-thyroid cancers rarely metastasize to the thyroid gland. Metastases can be divided into those with clinical expression and those identified at necropsy. Symptom producing thyroid metastases are usually due to a primary renal cell cancer. We report two cases of thyroid metastasis of a clear cell renal carcinoma. In the first case, an 82-year-old woman presented with an enlarged thyroid metastasis and identification of recurrent renal cell carcinoma which had been treated by radiotherapy 24 years earlier. After radiotherapy for a concomitant pulmonary metastasis, the patient is in good general health with no signs of recurrence. In the second case, increased thyroid volume led to signs of compression in a 71-year-old-man. The pathology report after left lobular thyroidectomy suggested trabecular adenoma or metastasis of a clear-cell primary tumour. Abdominal CT-scan revealed a 3.5 cm tumour found to be a clear-cell renal carcinoma at nephrectomy. Another osteolytic metastasis to the femur was also observed three months after surgery. The patient is in good health 15 months after the initial diagnosis. The significance of thyroid metastasis of renal cell carcinoma would vary according to the different cases reported in the literature with survival ranging from 32 months to 3-7 years after surgical exeresis. Prognosis would thus not appear to be as poor as for thyroid metastasis from other primary tumours. (authors). 24 refs

    Lung cancer is characterized by the highest incidence of solid tumor-related brain metastases, which are reported the incidence ranged 20% to 65%. This is also one of the reasons why it can cause significant mortality. Molecular targeted therapy plays a major role in the management of brain metastases in lung cancer. Targeted agents have become the novel methods for the treatment of lung cancer with brain metastases beyond the whole brain radiation therapy, stereotactic radiosurgery and chemo...

    Pre-therapeutic prediction of outcome is important for clinicians and patients in determining whether selective internal radiation therapy (SIRT) is indicated for hepatic metastases of colorectal cancer (CRC). Pre-therapeutic characteristics of 100 patients with colorectal liver metastases (CRLM) treated by radioembolization were analyzed to develop a nomogram for predicting survival. Prognostic factors were selected by univariate Cox regression analysis and subsequent tested by multivariate analysis for predicting patient survival. The nomogram was validated with reference to an external patient cohort (n = 25) from the Bonn University Department of Nuclear Medicine. Of the 13 parameters tested, four were independently associated with reduced patient survival in multivariate analysis. These parameters included no liver surgery before SIRT (HR:1.81, p = 0.014), CEA serum level ≥ 150 ng/ml (HR:2.08, p = 0.001), transaminase toxicity level ≥2.5 x upper limit of normal (HR:2.82, p = 0.001), and summed computed tomography (CT) size of the largest two liver lesions ≥10 cm (HR:2.31, p < 0.001). The area under the receiver-operating characteristic curve for our prediction model was 0.83 for the external patient cohort, indicating superior performance of our multivariate model compared to a model ignoring covariates. The nomogram developed in our study entailing four pre-therapeutic parameters gives good prediction of patient survival post SIRT. (orig.)

    To review the preventive approaches for recurrence after curative resection of hepatic metastases from coloreclal carcinoma, we have summarized all available publications reporting randomized control trials (RCTs) covered in PubMed. The treatment approaches presented above include adjuvant intrahepatic arterial infusion chemotherapy,systemic chemotherapy, neoadjuvant chemotherapy, and immunotherapy. Although no standard treatment has been established, several approaches present promising results, which are both effective and tolerable in posthepatectomy patients. Intrahepatic arterial infusion chemotherapy should be regarded as effective and tolerable and it increases overall survival (OS) and diseasefree survival (DFS) of patients, while 5-fluorouracil-based systemic chemotherapy has not shown any significant survival benefit. Fortunately chemotherapy combined with hepatic arterial infusion and intravenous infusion has shown OS and DFS benefit in many researches. Few neoadjuvant RCT studies have been conduced to evaluate its effect on prolonging survivals although many retrospective studies and case reports are published in which unresectable colorectal liver metastases are downstaged and made resectable with neoadjuvant chemotherapy.Liver resection supplemented with immunotherapy is associated with optimal results; however, it is also questioned by others. In conclusion, several adjuvant approaches have been studied for their efficacy on recurrence after hepatectomy for liver metastases from colorectal cancer (CRC), but multi-centric RCT is still needed for further evaluation on their efficacy and systemic or local toxicities. In addition, new adjuvant treatment should be investigated to provide more effective and tolerable methods for the patients with resectable hepatic metastases from CRC.

  8. Roentgenosemiotics of thyroid cancer metastases to the bones

    International Nuclear Information System (INIS)

    An analysis of X-ray findings in 146 cases of metastatic skeletal involvement in thyroid cancer (TC) led to the following conclusions: the formation of solitary foci of osteoclastic type mainly in the central parts of the skeleton (the vertebral column, ribs, pelvic bones) was typical of TC metastasizing to the bones. Metastatic growth was more often accompanied by bone distention (38.1%) than by the formation of major bone defects (18.2%), showing a tendency to rather slow growth. With tumor growth, the involvement of the adjacent bones via the ligamentous-articular apparatus and interverterbral disks was nated, metastases being localized in the vertebrae, costal articular parts, and the adjacent parts of the iliac bones and sacrum

    Presentation of techniques and procedures for regional chemotherapy in the treatment of unresectable liver metastases from different primary tumors as a modality of interdisciplinary therapy management. Such transarterial therapy methods include hepatic arterial infusion (HAI), transarterial chemoembolization (TACE), chemoembolization with cytostatic-loaded microspheres (DEBs), transarterial embolization (TAE) and selective internal radiation therapy (SIRT). Regional chemotherapy procedures in the treatment of liver metastases represent a minimally invasive treatment option that can be successfully combined with surgical resection and/or radiofrequency (RFA), laser-induced thermotherapy (LITT), microwave ablation (MWA). These procedures allow optimization of the local control rate with strictly intrahepatic processes and lead to increased survival rates without any quality of life restriction. (orig.)

    Full Text Available Abstract Background Besides being the effectors of native anti-tumor cytotoxicity, NK cells participate in T-lymphocyte responses by promoting the maturation of dendritic cells (DC. Adherent NK (A-NK cells constitute a subset of IL-2-stimulated NK cells which show increased expression of integrins and the ability to adhere to solid surface and to migrate, infiltrate, and destroy cancer. A critical issue in therapy of metastatic disease is the optimization of NK cell migration to tumor tissues and their persistence therein. This study compares localization to liver metastases of autologous A-NK cells administered via the systemic (intravenous, i.v. versus locoregional (intraarterial, i.a. routes. Patients and methods A-NK cells expanded ex-vivo with IL-2 and labeled with 111In-oxine were injected i.a. in the liver of three colon carcinoma patients. After 30 days, each patient had a new preparation of 111In-A-NK cells injected i.v. Migration of these cells to various organs was evaluated by SPET and their differential localization to normal and neoplastic liver was demonstrated after i.v. injection of 99mTc-phytate. Results A-NK cells expressed a donor-dependent CD56+CD16+CD3- (NK or CD56+CD16+CD3+ (NKT phenotype. When injected i.v., these cells localized to the lung before being visible in the spleen and liver. By contrast, localization of i.a. injected A-NK cells was virtually confined to the spleen and liver. Binding of A-NK cells to liver neoplastic tissues was observed only after i.a. injections. Conclusion This unique study design demonstrates that A-NK cells adoptively transferred to the liver via the intraarterial route have preferential access and substantial accumulation to the tumor site.

We describe these lesions and assess risk factors and impacts on postresection morbidity and mortality in naive patients to chemotherapy before the era of bevacizumab. Methods. Noncancerous liver tissue lesions were analysed according to tumour, chemotherapy, surgery, and patient characteristics. Results. Fifty patients aged 62 ± 9.3 years were included between 2003 and 2007. Thirty-three (66% received chemotherapy, with Folfox (58%, Folfiri (21%, LV5FU2 (12%, or Xelox (9% regimens. Hepatotoxicity consisted of 18 (36% cases of severe sinusoidal dilatation (SD, 13 (26% portal fibrosis, 7 (14% perisinusoidal fibrosis (PSF, 6 (12% nodular regenerative hyperplasia (NRH, 2 (4% steatosis >30%, zero steatohepatitis, and 16 (32% surgical hepatitis. PSF was more frequent after chemotherapy (21% versus 0%, , especially LV5FU2 (. SD was associated with oxaliplatin (54.5% versus 23.5%, and low body mass index (. NRH was associated with oxaliplatin ( and extensive resection (. No impact on mortality and morbidity was observed, apart postoperative elevation of bilirubin levels in case of PSF (, longer hospitalization in case of surgical hepatitis (, and greater blood loss in case of portal fibrosis (. Conclusions. Chemotherapy of colorectal liver metastases induces sinusoidal dilatation related to oxaliplatin and perisinusoidal fibrosis related to 5FU, without any impact on postoperative mortality.

    Full Text Available Patients with triple receptor-negative breast cancer often develop aggressive metastatic disease, which also might involve the brain. In many cases, systemic and local treatment is needed. It is important to consider the toxicity of chemo- and radiotherapy, especially when newly approved drugs become available. Randomised studies leading to drug approval often exclude patients with newly diagnosed brain metastases. Here we report our initial experience with eribulin mesylate and whole-brain radiotherapy (WBRT in a heavily pretreated patient with multiple brain, lung, and bone metastases from triple receptor-negative breast cancer. Eribulin mesylate was given after 4 previous lines for metastatic disease. Two weeks after the initial dose, that is, during the first cycle, the patient was diagnosed with 5 brain metastases with a maximum size of approximately 4.5 cm. She continued chemotherapy and received concomitant WBRT with 10 fractions of 3 Gy. After 3 cycles of eribulin mesylate, treatment was discontinued because of newly diagnosed liver metastases and progression in the lungs. No unexpected acute toxicity was observed. The only relevant adverse reactions were haematological events after the third cycle (haemoglobin 9.5 g/dL, leukocytes 3.1×109/L. The patient died from respiratory failure 18.5 months from diagnosis of metastatic disease, and 2.7 months from diagnosis of brain metastases. To the best of our knowledge, this is the first report on combined WBRT and eribulin mesylate.

    In patients with colorectal liver metastases (CLM), liver resection offers the possibility of cure and long-term survival. The liver is a highly immunogenic organ harboring ~80% of the body's tissue macrophages. Emerging data demonstrate a critical role of the immune response for cancer treatment. We investigated variations within genes involved in immune response checkpoints and their association with outcomes in patients with CLM who underwent neoadjuvant chemotherapy including bevacizumab and liver resection. Single-nucleotide polymorphisms (SNPs) in nine genes (CCL2, CCR2, LAG3, NT5E, PDCD1, CD274, IDO1, CTLA4 and CD24) were analyzed in genomic DNA from 149 patients with resected bevacizumab-pretreated CLM by direct Sanger DNA sequencing, and correlated with response, recurrence-free survival (RFS), overall survival (OS), probability of cure and recurrence patterns. IDO1 (indoleamine 2, 3-dioxygenase) rs3739319 G>A and CD24 rs8734 G>A showed a significant difference in 3-year OS rates. In addition, IDO1 rs3739319 G>A was significantly associated with extrahepatic recurrence. Recursive partitioning analyses revealed that IDO1 rs3739319 G>A was the dominant SNP predicting RFS and OS. Our data suggest that variants within genes involved in immune response checkpoints are associated with outcomes in patients with resected CLM and might lead to improved treatment strategies modulating anti-tumor immune response by targeting novel immune checkpoints.

    AIM: To select accurately good candidates of hepatic resection for colorectal liver metastasis.METHODS: Thirteen clinicopathological features, which were recognized only before or during surgery, were selected retrospectively in 81 consecutive patients in one hospital (Group Ⅰ ). These features were entered into a multivariate analysis to determine independent and significant variables affecting long-term prognosis after hepatectomy. Using selected variables, we created a scoring formula to classify patients with colorectal liver metastases to select good candidates for hepatic resection. The usefulness of the new scoring system was examined in a series of 92 patients from another hospital (Group Ⅱ ), comparing the number of selected variables.RESULTS: Among 81 patients of Group Ⅰ, multivariate analysis, i.e. Cox regression analysis, showed that multiple tumors, the largest tumor greater than 5 cm in diameter, and resectable extrahepatic metastases were significant and independent prognostic factors for poor survival after hepatectomy (P < 0.05). In addition, these three factors: serosa invasion, local lymph node metastases of primary cancers, and postoperative disease free interval less than 1 year including synchronous hepatic metastasis, were not significant,however, they were selected by a stepwise method of Cox regression analysis (0.05 < P < 0.20). Using these six variables, we created a new scoring formula to classify patients with colorectal liver metastases. Finally,our new scoring system not only classified patients in Group Ⅰ very well, but also that in Group Ⅱ, according to long-term outcomes after hepatic resection. The positive number of these six variables also classified them well.CONCLUSION: Both, our new scoring system and the positive number of significant prognostic factors are useful to classify patients with colorectal liver metastases in the preoperative selection of good candidates for hepatic resection.

    Purpose. To present thermal ablation of liver metastases via laser induced thermotherapy. Material and methods. Different technical procedures of thermal ablation and online monitoring are used, as there are the MR-guided laser induced thermotherapy (LITT) and the radiofrequency ablation thermotherapy (RF). Results. In a prospective non randomized study 606 patients with liver metastases were treated via MR-guided laserinduced thermotherapy. Inclusion criteria were the exclusion of extrahepatic tumor spread and a number of metastases lower than 5 and a size lower than 50 mm in diameter. The local tumor control rate in the 3 month and 6 month control study was 98,3%, the complication rate 3,5% (clinically relevant: 1,2%). The mean survival rate was 40,9 months for all patients with liver metastases without statistically relevant differences for various primaries, like colorectal carcinoma, breast cancer and various other tumors. Results for radiofrequency are so far limited with incidence of a higher local tumor recurrence rate versus LITT. Conclusion. MR-guided LITT results in a high local tumor control rate with improved survival. (orig.) [German] Zielsetzung.

    Abstract Patients with encapsulated colorectal liver metastases (CRLM) have a better prognosis than those without a capsule. The reason for the encapsulation is unknown. Hypoxia inducible factor-1α (HIF-1α) increases tumor angiogenesis and tumor tissue expression is associated with reduced survival. Our aim was to determine whether the good prognosis of encapsulated CRLM is associated with reduced HIF-1α expression by the cancer. The study selected only patients who had not undergone neoadjuvant chemotherapy prior to a potentially curative hepatectomy for CRLM. From 30 selected patients, serial sections were cut from a single randomly selected metastasis. Morphology was assessed following H&E staining. Tumor hypoxia, vascular endothelial growth factor (VEGF), proliferation, and microvascular density (MVD) were assessed by immunostaining for HIF-1α and carbonic anhydrase-9 (CA-9), VEGF, Ki67, and cluster of differentiation-31, respectively. MVD was calculated in the vascular hot spots. Pathology was reported without clinical outcome information. Actual long-term survival was recorded. Thirteen (43%) of the cancers were encapsulated CRLM containing glands which were large, complex, and cribriform. Thirteen (43%) were infiltrative CRLM and their glands were small, closely packed, and rounded with vessels in the interglandular fibrous tissue with no capsule; 3 (10%) had a mixed picture. Encapsulated CRLM had a higher expression of HIF-1α (58% vs 8%, P = 0.03), CA-9 (42% vs 0%, P = 0.04), and VEGF (92% vs 25%, P = 0.02). MVD was lower in the encapsulated CRLM group (37 mm2 vs 143 mm2, P < 0.001). The median follow-up was 115 months. The encapsulated CRLM group had a better overall and 5-year survival (relative hazard: 0.58, P = 0.057 and hazard ratio: 0.52, P = 0.044). There are 2 main morphological appearances of CRLM which have very different long-term survival following liver resection surgery. The morphology is associated with

  19. Detectability of liver metastases in malignant melanoma: prospective comparison of magnetic resonance imaging and positron emission tomography

    International Nuclear Information System (INIS)

    Purpose: We evaluated the diagnostic accuracy of magnetic resonance imaging (MRI) and positron emission tomography (PET) for detection of liver metastases in malignant melanoma. Material and methods: Thirty-five patients with 39 combined unenhanced MRI and fluorine-18 deoxyglucose (F-18 FDG) PET scans were prospectively studied. In discordant imaging findings final diagnosis was proven by clinical follow-up >6 months and demonstration of progressive liver metastases by at least one imaging method. Sensitivities and specificities were compared and the influence of lesion size and melanin content on diagnostic accuracy was determined. Results: MRI and PET were concordantly negative for presence and number of liver metastases in 28 patients and positive in four patients. PET and MRI were false positive in one patient each. In one patient MRI showed a single metastases not seen by PET and in one patient MRI demonstrated more metastases at the first examination. In follow-up investigations MRI revealed more metastases than PET in both patients. The sensitivities for lesion detection were 47% (16/34) for PET and 100% for MRI. Lesion detectability by PET was related to lesion size (P < 0.0001) but not to melanin content. Conclusion: MRI is more sensitive in the detection of liver metastases in patients with malignant melanoma. Small lesions are easily missed by PET, while melanin content does not influence detectability by PET

    The paper discusses the capability for active movement in an extracellular matrix, wherein remodeling of the cytoskeleton by actin binding proteins plays a significant role in metastases formation. We studied the expression of actin binding proteins and β-catenin in tissues of primary tumors and metastases of ovarian and breast cancer. Contents of p45 Ser β-catenin and the actin severing protein gelsolin were decreased in metastases of ovarian cancer relative to primary tumors. The level of the cofilin, functionally similar to gelsolin, was significantly higher in metastases compared to primary ovarian and breast tumor tissue. In breast cancer, significant increase in the number of an actin monomer binder protein thymosin-β4 was observed in metastases as compared to primary tumors. The data obtained suggest the involvement of locomotor proteins in metastases formation in ovarian and breast cancer.

    Pediatric nasopharyngeal carcinoma (NPC) is rare and usually poorly differentiated. We report a 14-year-old boy with NPC with metastases to liver, spleen, lymph nodes and bone marrow. The liver metastases closely resembled benign cystic liver disease on imaging; however, they showed intense uptake similar to other metastatic sites on positron emission tomography (PET) scan. A liver biopsy could not be performed on the boy. The boy responded clinically to platinum-based chemotherapy, and all the baseline PET-positive lesions became negative. This case highlights the rarity of splenic and cystic liver metastases in pediatric NPC and demonstrates the potential use of PET/CT in diagnosis, staging and response assessment in metastatic pediatric NPC.

    The prognosis for patients with liver metastases depends on the therapeutic options regarding the treatment of the primary tumor, co-existing extrahepatic metastases and the extent and treatment possibilities of the hepatic metastases themselves. Numerous curative or palliative oncological therapeutic concepts have been introduced in case of non-resectable liver metastases to prolong survival while maintaining a highest possible quality of life. Cryotherapy, which can be performed percutaneously and under magnetic resonance guidance, is one of these manifold therapeutic modalities, combining the inherent advantages of MRI with minimal invasiveness. Excellent visualization of the frozen liver tissue, precise tumor ablation, as well as an almost painless intervention due to the analgetic effect of the ice are implicating percutaneous cryotherapy as an attractive alternative to other ablation techniques. First clinical results are promising. However, meticulous and extensive long-term evaluation on a broad clinical scale is required. (orig.) [German] Die Prognose eines Patienten mit hepatischen Filiae haengt von den Behandlungsmoeglichkeiten des Primaertumors, vom Vorhandensein weiterer Metastasen und von der Ausdehnung und den Behandlungsmoeglichkeiten der Lebermetastasen selbst ab. Bei chirurigsch nicht resektablen Lebermetastasen kommen zahlreiche kurative oder palliative onkologische Therapiekonzepte in Frage, saemtlich mit dem Ziel einer moeglichst hohen Ueberlebensrate und Lebensqualitaet. Eine dieser Therapiestrategien ist die Kryotherapie, die perkutan unter kernspintomographischer Kontrolle durchgefuehrt werden kann und somit die inhaerenten Vorteile der MRT mit einem wenig invasiven Verfahren verbindet. Eine exzellente Darstellbarkeit gefrorenen Lebergewebes, eine praezise Tumorablation sowie ein nahezu schmerzfreier Eingriff aufgrund des analgetischen Effektes tiefer Temperaturen machen die perkutane Kryotherapie zu einer attraktiven Alternative zu anderen

  5. Safety margin in irradiation of colorectal liver metastases: assessment of the control dose of micrometastases

    International Nuclear Information System (INIS)

    Micrometastases of colorectal liver metastases are present in up to 50% of lesions. In this study we sought to determine the threshold dose for local control of occult micrometastases in patients undergoing CT (computed tomography)-guided brachytherapy of colorectal liver metastases. Nineteen patients demonstrated 34 local tumor recurrences originating from micrometastases after CT-guided brachytherapy of 27 colorectal liver metastases. We considered a local tumor recurrence as originating from a micrometastasis if tumor regrowth occurred adjacent to a formerly irradiated lesion and the distance of the 3D isocenter of the new lesion was ≤ 23.5 mm from the previous tumor margin. Follow-up MRI was fused with the planning-CT and dosimetry data. Two reviewers independently indicated the dose exposure at the isocenter of the micrometastases. Statistical analysis included an analysis of variance (ANOVA) using backward selection. 95% tolerance intervals with coverage of 87.5 and 75% of the data of the normal distribution were calculated. The median distance of the micrometastases to the margin of the originating colorectal metastases was 8.75 mm (1-21 mm). Dose exposure at the isocenter was 12.25 Gy (7-19.8) in median. We stratified according to the distance from the isocenter to the initial tumor margin: ≤ 9 mm, > 9-15 mm and > 15 mm. The median dose in the according isocenters was 13.18, 11.6 and 11.85 Gy. The threshold dose failing to prevent micrometastasis growth was sigificantly higher in a subgroup of lesions with ≤ 9 mm distance as compared to > 15 mm (13.18 vs 11.85 Gy). Adjuvant chemotherapy correlated with greater distance of micrometastasis growth to the tumor but not with the threshold dose. To prevent loss of local tumor control by continuous growth of micrometastases a threshold dose of 15,4 Gy (single fraction) should be delivered at a distance of 21 mm to the gross tumor margin

    Full Text Available  Analysis of rate of relapses and metastases with well-differentiated thyroid cancer was performed for patients in 2009 to 2013. The study involved 189 patients with thyroid cancer including 98 (51.9 % patients suffering from papillary thyroid cancer, 77 (40.7 % patients suffering from follicular thyroid cancer, and 14 (7.4 % patients suffering from medullary thyroid cancer. 2.04 % of the 98 patients suffering from papillary thyroid cancer manifested a relapse, and lymphogenic metastases of cancer were revealed with 1.0 % of patients. With follicular thyroid cancer (n = 77, lymphogenic metastases were registered in 7.8 % of cases, relapses were revealed in 1.3 % of cases. This analysis demonstrated that observation of patients for 5 years revealed a higher percentage of metastases with patients that suffered from follicular thyroid cancer.

    Von Meyenburg complexes (VMC) are a cluster of benign liver malformations including biliary cystic lesions, with congenital fibrocollagenous stroma. This rare entity can mimick multiple secondary hepatic lesions. We report a case of a 56-year-old woman who had multiples liver lesions 12 years after operation for breast cancer. Biopsy of the hepatic lesion confirmed the diagnosis of VMC. Preoperative discovery of multiple gray-white nodular lesions scattered on the surface of the liver should not always contraindicate curative liver resection. The diagnosis of VMC should be known and confirmed with liver biopsy. PMID:21103275

  8. Individualized image guided iso-NTCP based liver cancer SBRT

    International Nuclear Information System (INIS)

    A highly individualized stereotactic body radiotherapy (SBRT) strategy was developed to allow a wide spectrum of patients with liver cancer to be treated. This phase I/II study encompasses individualization of immobilization, radiation planning, PTV margin determination, image guidance strategy and prescription dose. Active breathing control breath hold is used to immobilize the liver when feasible. Image guidance strategies include orthogonal MV images and orthogonal kV fluoroscopy using the diaphragm for a surrogate for the liver, and kV cone beam CT using the liver or tumour for guidance. The prescription dose is individualized to maintain the same estimated risk of radiation-induced liver disease (RILD), based on a normal tissue complication probability (NTCP) model, with a maximum permitted dose of 60 Gy in 6 fractions. Since August 2003, 79 patients with hepatocellular carcinoma (33), intrahepatic cholangiocarcinoma (12) and liver metastases (34) were treated. The median tumour volume was 293 cm3 (2.9-3088 cm3). The median prescribed dose was 36.6 Gy (24.0 Gy-57.0 Gy) in 6 fractions. The median effective liver volume irradiated was 45% (9-80%). Sixty percent of patients were treated with breath hold to immobilize their liver. Intra-fraction reproducibility (s) of the liver with repeat breath holds was excellent (1.5?mm); however inter-fraction reproducibility (s) was worse (3.4 mm). Image guidance reduced the residual systematic and random setup errors significantly

    Full Text Available Following failure of systemic chemotherapy, transarterial chemoembolization (TACE is an available method to control unresectable liver metastases from colorectal carcinoma (CRC. The aim of present study was to evaluate the efficacy of chemoembolization for inoperable metastatic liver lesions from CRC. Forty-five CRC patients with liver metastases resistant to systemic chemotherapy were enrolled in our study. For each patient, three session of TACE were conducted with 45 days interval. A combination of mitomycin, doxorubicin, and lipiodol were used for TACE. A tri-phasic computed tomography scan and biochemical laboratory tests were performed for all patients at baseline and 30 days after each TACE. Image analysis included measurement of lesion diameters as well as contrast enhancement. Eleven patients deceased before completing three session and the final analyses were performed on the remaining 34 patients. Evaluation of a total 93 lesions in all patients after chemoembolization sessions revealed a 25.88% reduction in anteroposterior (AP diameter, 33.92% transverse (T diameter, and 42.22% in product of APxT diameter of lesions (P<0.001 for all instances. CT scan showed a total disappearance of 33% of lesions and evident reduction in contrast enhancement in 16% of them. There were no changes in contrast enhancement in 51% of lesions. Evaluation of single largest lesion in each patient revealed 57.32% reduction in AP diameter, 59.66% in T diameter, and 62.17% in product of APxT diameters (P<0.001 for all diameters. TACE offers a viable option for CRC patients with unresectable liver metastases by significantly reducing lesion size and contrast enhancement.

    Full Text Available The aim of this study was to compare the diagnostic accuracy of [18F]FDG-PET/MRI with PET/CT for the detection of liver metastases.32 patients with solid malignancies underwent [18F]FDG-PET/CT and subsequent PET/MRI of the liver. Two readers assessed both datasets regarding lesion characterization (benign, indeterminate, malignant, conspicuity and diagnostic confidence. An imaging follow-up (mean interval: 185±92 days and/-or histopathological specimen served as standards of reference. Sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV were calculated for both modalities. Accuracy was determined by calculating the area under the receiver operating characteristic (ROC curve. Values of conspicuity and diagnostic confidence were compared using Wilcoxon-signed-rank test.The standard of reference revealed 113 liver lesions in 26 patients (malignant: n = 45; benign: n = 68. For PET/MRI a higher accuracy (PET/CT: 82.4%; PET/MRI: 96.1%; p<0.001 as well as sensitivity (67.8% vs. 92.2%, p<0.01 and NPV (82.0% vs. 95.1%, p<0.05 were observed. PET/MRI offered higher lesion conspicuity (PET/CT: 2.0±1.1 [median: 2; range 0-3]; PET/MRI: 2.8±0.5 [median: 3; range 0-3]; p<0.001 and diagnostic confidence (PET/CT: 2.0±0.8 [median: 2; range: 1-3]; PET/MRI 2.6±0.6 [median: 3; range: 1-3]; p<0.001. Furthermore, PET/MRI enabled the detection of additional PET-negative metastases (reader 1: 10; reader 2: 12.PET/MRI offers higher diagnostic accuracy compared to PET/CT for the detection of liver metastases.

    OBJECTIVE To evaluate the safety and effectiveness of treatment of hepatic metastases from colorectal cancer using high-intensity focused ultrasound (HIFU). METHODS Thirty-one lesions in 18 patients with hepatic metastases from colorectal cancer after colectomy were treated with HIFU therapy. The vital signs, function of the vital organs, complications and pathological outcome were studied using imaging examinations such as CT or MRI. RESULTS The vital signs of all patients remained stable and their liver and kidney functions normal. Two of the 18 patients were not followed-up. After a mean follow-up of 16.1 months (6-38 months), 13 survived. The survival rates at the 12th and 18th months were 83.3% and 66.7%, respectively. The median survival rate was 16 months. Among the 25 lesions followed-up, 17 shrank over 50%, 5 grew new metastases and superficial degree II skin injury occurred in 8. CONCLUSION HIFU is a safe, effective and non-invasive option for the treatment of hepatic metastases from colorectal cancer.

    Colorectal cancer metastasis to the liver is a major cause of cancer-related death; however, the genes and pathways that govern this metastatic colonization event remain poorly characterized. Here, using a large-scale in vivo RNAi screen, we identified liver and red blood cell pyruvate kinase (PKLR) as a driver of metastatic liver colonization. PKLR expression was increased in liver metastases as well as in primary colorectal tumors of patients with metastatic disease. Evaluation of a murine liver colonization model revealed that PKLR promotes cell survival in the tumor core during conditions of high cell density and oxygen deprivation by increasing glutathione, the primary endogenous antioxidant. PKLR negatively regulated the glycolytic activity of PKM2, the major pyruvate kinase isoenzyme known to regulate cellular glutathione levels. Glutathione is critical for metastasis, and we determined that the rate-limiting enzyme of glutathione synthesis, GCLC, becomes overexpressed in patient liver metastases, promotes cell survival under hypoxic and cell-dense conditions, and mediates metastatic liver colonization. RNAi-mediated inhibition of glutathione synthesis impaired survival of multiple colon cancer cell lines, and pharmacological targeting of this metabolic pathway reduced colonization in a primary patient-derived xenograft model. Our findings highlight the impact of metabolic reprogramming within the niche as metastases progress and suggest clinical potential for targeting this pathway in colorectal cancer. PMID:26784545

  14. Angiographic and CT findings after intra-arterial cytostasis of colorectal liver metastases

    International Nuclear Information System (INIS)

    Between October 1983 and January 1986, sexteen patients with inoperable liver metastases from colorectal carcinomas were treated by single or cyclical intraarterial chemotherapy introduced either through an angiographic catheter or by means of a subcutaneously implanted access point (Port-A-Cath). Before each treatment cycle, the position of the catheter and the state of the vessels was examined by subtraction angiography in order to avoid complications and to confirm that the cytostatic agents were actually perfusing metastases, as shown by angio-CT. The complementary nature of the information obtained by these methods and their superiority over scintigraphy with 99mTc macroaggregated albumin particles is documented and the most frequent complications of regional tumour therapy are described.

    International Nuclear Information System (INIS)

    Using receiver operating characteristics (ROCs) the authors have compared the diagnostic performance of new pulse sequence techniques, including the application of presaturation pulses and fast imaging techniques. Forty- two patients with proven primary cancer were studied at 1.5 T. MR images included T1-weighted spin echo (SE) images (SE 800/15/4 repetition time msec/ echo time msec/NSQ), proton density-weighted images (SE 2,000/15/2), and T2-weighted images (SE 800/70/4 and SE 2,000/70/2). Fast imaging with suspended respiration was performed with T1-weighted fast low-angle shot (FLASH) 60 degrees (100/6/1) and T2-weighted FLASH 15 degrees (80/10/1) sequences. The ROC analysis was based on 300 images without and 300 images with hepatic lesions proved by intraoperative findings. All three radiologists achieved significantly (P < .05) better results with SE 2,000/70 and T1-weighted FLASH 60 degrees sequences than with the SE 800/15, SE 2,000/15, or T2-weighted FLASH 15 degrees sequences

    We wanted to assess the safety and efficacy of performing radiofrequency ablation (RFA) in patients with non-colorectal liver metastases. In this retrospective study, 25 patients with 40 hepatic metastases (M:F = 17:8; mean age, 57 years; tumor size, 0.5-5.0 cm) from a non-colorectal origin (stomach, biliary, breast, pancreas, kidney and skin) were treated with RFA. The RFA procedures were performed using either an internally cooled electrode or a clustered electrode under ultrasound or CT guidance. Contrast-enhanced CT scans were obtained immediately after RFA and follow-up CT scans were performed within three months after ablation and subsequently at least every six months. The intrahepatic disease-free interval was estimated and the overall survival from the time of the initial RFA was analyzed using the Kaplan-Meier method. No intraprocedural deaths occurred, but four major complications developed, including abscesses (n = 3) and pneumothorax (n 1). Technical effectiveness was determined on the initial follow-up images. During the follow-up period (range, 5.9-68.6 months; median time, 18.8 months) for 37 tumors in 22 patients where technical effectiveness was achieved, 12 lesions (32%, 12 of 37) showed local tumor progression and new intrahepatic metastases occurred in 13 patients (59%, 13 of 22). The median intrahepatic disease-free interval was 10.1 months. The 1-year, 3-year and 5-year overall survival rates after RFA were 86%, 39% and 19%, respectively RFA showed intermediate therapeutic effectiveness for the treatment of non-colorectal origin liver metastases.

    To compare diffusion-weighted (DW) and T2-weighted MR imaging in detecting colorectal liver metastases in a rat model, using histological examination as a reference method. Eighteen rats had four liver injections of colon cancer cells. MR examinations at 7 T included FSE-T2-weighted imaging and SE-DW MR imaging (b = 0, 20 and 150 s/mm{sup 2}) and were analysed by two independent readers. Histological examination was performed on 0.4-mm slices. McNemar's test was used to compare the sensitivities and the Wilcoxon matched pairs test to compare the average number of false-positives per rat. One hundred and sixty-six liver metastases were identified on histological examination. The sensitivity in detecting liver metastases was significantly higher on DW MR than on T2-weighted images (99/166 (60 %) (reader 1) and 92/166 (55 %) (reader 2) versus 77/166 (46 %), P {<=} 0.001), without an increase in false-positives per rat (P = 0.773/P = 0.850). After stratification according to metastasis diameter, DW MR imaging had a significantly higher sensitivity than T2-weighted imaging only for metastases with a diameter (0.6-1.2 mm) similar to that of the spatial resolution of MR imaging in the current study. This MR study with histological correlations shows the higher sensitivity of DW relative to T2-weighted imaging at 7 T for detecting liver metastases, especially small ones. (orig.)

  1. A prospective trial of short-fractionation radiotherapy for the palliation of liver metastases

    International Nuclear Information System (INIS)

    The purpose of this study was to prospectively examine the effectiveness and tolerability of a simple radiotherapy technique for the palliation of symptomatic liver metastases. Twenty-eight patients with symptomatic liver metastases were enrolled from seven centres, and received targeted (partial or whole) liver irradiation consisting of 10 Gy in two fractions over 2 days. Symptoms at baseline were hepatic pain (27 patients), abdominal distension (19), night sweats (12), nausea (18) and vomiting (eight). Twenty-two patients (76%) had failed previous treatment with chemotherapy, hormonal therapy and/or high-dose steroids. Symptoms and potential toxicities were prospectively assessed at the time of treatment, then 2, 6 and 10 weeks later. Individual symptom response rates were 53-66% at 2 weeks. Partial or complete global symptomatic responses were noted in 15 patients (54%) overall. The treatment was well tolerated with two patients (7%) experiencing grade 3 toxicity (one vomiting and one diarrhoea); however, four patients reported temporary worsening of pain shortly after treatment. This simple and well-tolerated treatment achieves useful palliation. Copyright (2003) Blackwell Science Pty Ltd

    Gastrointestinal neuroendocrine tumors (NET) frequently present with unresectable hepatic metastases, which poses a barrier for curative treatment. Resection of the primary tumor and subsequent orthotopic liver transplantation (OLT) has been proposed as a treatment approach but available data in this regard is limited. We present a clinical case of an otherwise asymptomatic 44-yo man complaining of abdominal pain and dyspepsia that was diagnosed of a 10 cm duodenal tumor with multiple hepatic metastases. A CT-guided biopsy confirmed a NET. He underwent first a Whipple's procedure, and then was listed for liver transplantation. During the waiting time a multimodal therapeutic approach was used including the use of radioactive 177lutetium-labeled somatostatin analogues, long-acting somastostatin analogues and antiangiogenic antibodies (bevacizumab) in order to keep neoplastic disease under control. Two years after Whipple's procedure and given disease stability he underwent OLT with an uneventful postoperative evolution. Patient condition and graft function are optimal after a 4-year follow-up period with no evidence of recurrence. This case report underscores how a multimodal approach involving careful patient selection, resective surgery as well as use of somatostatin analogues and antiangiogenic biological therapy followed by liver transplantation can achieve excellent long-term results in this difficult patient population.

  3. Image-based response assessment of liver metastases following stereotactic body radiotherapy with respiratory tracking

    International Nuclear Information System (INIS)

    To describe post-CyberKnife® imaging characteristics of liver metastases as an aid in assessing response to treatment, and a novel set of combined criteria (CC) as an alternative to response according to change in size (RECIST). Imaging data and medical records of 28 patients with 40 liver metastases treated with stereotactic body radiotherapy (SBRT) were reviewed. Tumor size, CT attenuation coefficient, and contrast enhancement of lesions were evaluated up to 2 years post SBRT. Rates of local control, progression-free survival, time to progression, and overall survival according to RECIST and CC were estimated. Complete response (CR) was 3.6% (95% CI: 0.1–18%) and 18% (95% CI: 6–37%) according to RECIST and combined criteria, respectively. Two progressive diseases and two partial responses according to RECIST were classified as CR by the combined criteria and one stable response according to RECIST was classified as progressive by CC (Stuart-Maxwell test, p = 0.012). The disease control rate was 60.7% (95% CI: 41–78%) by RECIST and 64% (95% CI: 44%–81%) by CC. Use of response criteria based on change in size alone in the interpretation of liver response to SBRT may be inadequate. We propose a simple algorithm with a combination of criteria to better assess tumor response. Further studies are needed to confirm their validity

    2015-01-01

    Full Text Available Lung cancer is the most common cause of cancer related mortality in men and women. Approximately 15% of lung cancers are small cell type. Chemotherapy and radiation are the mainstay treatments. Currently, the standard chemotherapy regimen includes platinum/etoposide. For extensive small cell lung cancer, irinotecan and cisplatin have also been used. Patients with relapsed small cell lung cancer have a very poor prognosis, and the morbidity increases with brain metastases. Approximately 10%–14% of small cell lung cancer patients exhibit brain metastases at the time of diagnosis, which increases to 50%–80% as the disease progresses. Mean survival with brain metastases is reported to be less than six months, thus calling for improved regimens. Here we present a case series of patients treated with irinotecan for progressive brain metastases in small cell lung cancer, which serves as a reminder of the role of systemic chemotherapy in this setting.

  6. Radioimmunodetection of hepatic metastases from human colon cancer in nude mice with a gamma-detecting probe

    International Nuclear Information System (INIS)

    The utility of a gamma detecting probe (GDP) in the detection of experimental hepatic metastases in nude mice using radiolabeled monoclonal antibody (mAb) was assessed. Twelve mice with established hepatic metastases from the HT-29 LMM cell line, 5 mice with s.c. tumors in the left flank and 6 non-tumor-bearing control mice were given i.v. injections of 40 microCi/4 micrograms of 125I-labeled mAb HT-29-15. Six tumor-bearing mice were given i.v. injections of an isotype-matched control mAb (BL-3). Using the GDP, measurements were obtained daily over the region of the heart, the region of the liver (i.e., the right flank), and the s.c. tumor when applicable. Intraoperative measurements were obtained at laparotomy on days 5 and 7. Subsequently, the metastases, normal liver, and blood were resected and the radioactivity/g tissue was measured in a gamma well counter. External right flank/heart ratios were significantly higher in the tumor-bearing group than in controls. External measurements allowed detection of small tumors weighing only 161 ± 87 (SD) mg and occupying 11.5 ± 4% of the entire liver weight. Metastases counted intraoperatively with the GDP measured 1 to 7 mm in greatest diameter. The mean metastasis/heart GDP ratio was 1.7 ± 0.4:1. Tumors weighing as little as 51 ± 42 mg could be identified. These experimental results confirm the usefulness of the GDP for the detection of small hepatic metastases from colon cancer and illustrate important features of probe measurement of radiolabeled mAb uptake

  7. Stereotactic radiation therapy for liver metastases: factors affecting local control and survival

    International Nuclear Information System (INIS)

    To report on outcome and toxicity of stereotactic body radiotherapy (SBRT) for liver metastases in patients not eligible for surgery. From 2000 to 2009, 74 patients with 91 liver metastases from different primaries have been treated with SBRT at our institution. Median planning target volume was 123 ccm (range: 10.6-1074 ccm). Treatment consisted of 3–5 fractions with 5–12.5 Gy/ fraction prescribed to the surrounding 60-95% isodose with daily image guidance. Regular follow-up included CT or MRI imaging until tumor progression. Median local recurrence-free interval was 23 months with a local control rate of 74.7%, 48.3% and 48.3% after 1, 2 and 3 years. Only minimum biologically effective dose (BED) to gross tumor volume (GTV) remained as independent significant factor for local control in multivariate analysis. No local recurrences were observed in lesions (n = 12) which received a minimal BED to the GTV of 120 Gy. Including 26 local recurrences, 67 patients (91%) showed disease progression after SBRT with a median time of 5 months. Median overall survival was 27 months with survival rates of 77%, 30% and 27% at 1, 3 and 5 years. On multivariate analysis only GTV volume remained as independent significant prognostic factor for overall survival (p = 0.002). No grade 3 to 5 acute toxicity and no grade 4 or 5 late toxicity occurred. SBRT for liver metastases was well tolerated in this non-selected patient cohort and yielded good local control despite the considerable size of most lesions treated. Long-term survival is possible after SBRT. The online version of this article (doi:10.1186/s13014-015-0369-9) contains supplementary material, which is available to authorized users

  8. Calculated methods for table diagnosis of lung cancer metastases to regional lymph nodes

    International Nuclear Information System (INIS)

    The literary data and the author's material (132 patients with peripheral lung cancer and 112 patients with central lung cancer) are used to develop a technique for calculated table diagnosis of lung cancer metastases to regional lymph nodes. The results of table diagnostics are compared with therapeutic and computer diagnostics. The above technique improves the diagnostics of lung cancer metastases to regional lymph nodes by 20%. However, the results of table diagnostics of metastases are somewhat worse (2.8-4.4 %) than those of computer diagnosis. 5 refs.; 3 tabs

    Primary and secondary malignant liver cancers are some ofmost common malignant tumors in the world.Chemotherapy and radiotherapy are not very effectiveagainst them. Surgical resection has been considered theonly potentially curtive option, but the majority of patientsare not candidates for resection because of tumor size,location near major intrahepatic blood vessels and bileducts, precluding a margin-negative resection, cirrhotic,hepatitis virus infection or multifocial. Radiofrequenceablation (RFA), which is a new evolving effective andminimally invasive technique, can produce coagulativenecrosis of malignant tumors. RFA should be usedpercutaneously, laparscopically, or during the openlaparotomy under the guidance of ultrasound, CT scan andMRI. RFA has lots of advantages superior to other localtherapies including lower complications, reduced costs andhospital stays, and the possibility of repeated treatment. Ingeneral, RFA is a safe, effective treatment for unresectablemalignant liver tumors less than 7.0 cm in diameter. Wereview the principle, mechanism, procedures andexperience with RFA for treating malignant liver tumors.

    Full Text Available Hepatocellular carcinoma (HCC and liver metastases arecommon cancers worldwide. Recent imaging modalities havebeen able to detect HCC and liver metastases at an early stage,with surgical resection as the choice of management.However, because of poor liver reserve, co-existing liver cirrhosisand multiplicity of tumors, resection is only feasible in10-30% of HCC or liver metastases on presentation. Thus, variouslocal tumor ablation modalities are being developed toeffectively ablate small liver tumors. Of these, percutaneousethanol injection and radiofrequency (RF ablation (RFA arethe two best options because of their high effectiveness andminimal invasiveness. RFA has the particular advantage ofmore predictable ablation areas and fewer treatment sessionsrequired. It has been applied for local ablation of liver malignancysince 1990 and is currently widely accepted as an alternativeto resection in small, un-resectable or even resectable liver malignancies. Becausecurrent RF devices can only effectively ablate 3 cm tumors in a single RF electrode introduction,recent advances have focused exclusively on improving RF devices, including thedesign of electrodes and the algorithm to magnify the ablation zone in a single session orover a short duration. This review article updates results of RFA for HCC and liver metastasisin terms of complete ablation, local recurrence, overall survival, and recent advances inRFA for liver malignancy.

    Background and Aims. Chemotherapy of colorectal liver metastases can induce hepatotoxicity in noncancerous liver. We describe these lesions and assess risk factors and impacts on postresection morbidity and mortality in naive patients to chemotherapy before the era of bevacizumab. Methods. Noncancerous liver tissue lesions were analysed according to tumour, chemotherapy, surgery, and patient characteristics. Results. Fifty patients aged 62 ± 9.3 years were included between 2003 and 2007. Thirty-three (66%) received chemotherapy, with Folfox (58%), Folfiri (21%), LV5FU2 (12%), or Xelox (9%) regimens. Hepatotoxicity consisted of 18 (36%) cases of severe sinusoidal dilatation (SD), 13 (26%) portal fibrosis, 7 (14%) perisinusoidal fibrosis (PSF), 6 (12%) nodular regenerative hyperplasia (NRH), 2 (4%) steatosis >30%, zero steatohepatitis, and 16 (32%) surgical hepatitis. PSF was more frequent after chemotherapy (21% versus 0%, P = 0.04), especially LV5FU2 (P = 0.02). SD was associated with oxaliplatin (54.5% versus 23.5%, P = 0.05) and low body mass index (P = 0.003). NRH was associated with oxaliplatin (P = 0.03) and extensive resection (P = 0.04). No impact on mortality and morbidity was observed, apart postoperative elevation of bilirubin levels in case of PSF (P = 0.03), longer hospitalization in case of surgical hepatitis (P = 0.03), and greater blood loss in case of portal fibrosis (P = 0.03). Conclusions. Chemotherapy of colorectal liver metastases induces sinusoidal dilatation related to oxaliplatin and perisinusoidal fibrosis related to 5FU, without any impact on postoperative mortality.

    Surgical excision remains the preferred treatment for resectable hepatic metastases of neuroendocrine tumors. In cases of more disseminated hepatic disease, transarterial radioembolization with Yttrium-90- (90Y-) labeled microspheres has been demonstrated as a viable option for symptom and locoregional tumor control. On an outpatient basis, radioembolization can be utilized from early line to salvage phases, in various combinations with systemic therapies. Review of available data shows encouraging safety and efficacy profiles for the intraarterial application of 90Y for the treatment of mNETs of the liver. Symptom control and decrease in somatostatin analog use can be achieved, as well as prolonged survival. PMID:22235376

  15. Stereotactic radiosurgery with the gamma knife for brain metastases in patients with lung cancer

    International Nuclear Information System (INIS)

    Between February 1992 and April 1993, six patients with lung cancer were treated with gamma knife radiosurgery for brain metastases. Five patients had adenocarcinoma, and one patient had small cell carcinoma. Two patients had solitary metastases, and four patients had multiple metastases. Twelve metastases were treated with the gamma knife (peripheral dose between 12 Gy and 25 Gy). After radiosurgery, three complete and eight partial responses were achieved, which resulted in an overall response rate of 92%. In two patients, histological studies showed that few viable cells were surrounded by necrosis. Neurological status improved in all patients, and none died of complications. However, four of six patients later developed new intracranial metastases outside the treatment field. These data suggest that radiosurgery with the gamma knife is effective against brain metastases in patients with lung cancer, especially when the lesions are deep in the brain. (author)

    International Nuclear Information System (INIS)

    Objective: To compare the characteristics of the distribution of bone metastases in lung cancer, breast cancer and esophageal cancer. Methods: SPECT bone imaging of the entire body was performed after the injection of 99Tcm-methylene diphosphonate (99Tcm-MDP) in 454 cases. Analyzed the distribution of metastatic bone lesions in upper limbs' middle and distal or the pelvis and lower limbs and the distinction of metastatic bone lesions between different diseases were distinguished. Results: Of all the 454 patients, 130 cases showed abnormal radionuclide concentration in the region of upper limbs' middle and distal or the pelvis and lower limbs. One thousand three hundreds and three metastatic bone lesions were found in all the patients [893 were in lung cancer (64.4%), 36 1 were in breast cancer (27.7%) and 103 were in esophageal cancer (7.9%)]. Radioactive uptake in rotor area of femur lesions in these diseases was demonstrated to be of large proportion. Conclusions: The result of 99Tcm-MDP bone imaging shows that the distribution of the metastatic bone lesions in lung cancer, breast cancer and esophageal cancer vary from place to place. (authors)

    Liver Cancer has been a leading cause of death in Thailand. The purpose of this study was to model and forecast liver cancer mortality rate in Thailand using death certificate reports. A retrospective analysis of the liver cancer mortality rate was conducted. Numbering of 123,280 liver cancer causes of death cases were obtained from the national vital registration database for the 10-year period from 2000 to 2009, provided by the Ministry of Interior and coded as cause-of-death using ICD-10 by the Ministry of Public Health. Multivariate regression model was used for modeling and forecasting age-specific liver cancer mortality rates in Thailand. Liver cancer mortality increased with increasing age for each sex and was also higher in the North East provinces. The trends of liver cancer mortality remained stable in most age groups with increases during ten-year period (2000 to 2009) in the Northern and Southern. Liver cancer mortality was higher in males and increase with increasing age. There is need of liver cancer control measures to remain on a sustained and long-term basis for the high liver cancer burden rate of Thailand.

    AIM: To explore the feasibility of computed tomography (CT)-guided percutaneous ethanol injection (PEI) using a disposable curved needle for treatment of malignant liver neoplasms and their metastases in retroperitoneal lymph nodes.METHODS: CT-guided PEI was conducted using a disposable curved needle in 26 malignant liver tumors smaller than 5 cm in diameter and 5 lymph node metastases of liver cancer in the retroperitoneal space. The disposable curved needle was composed of a straight trocar (21G) and stylet, a disposable curved tip (25 G) and a fine stylet. For the tumors found in deep sites and difficult to reach, or for hepatic masses inaccessible to the injection using a straight needle because of portal vein and bile ducts, the straight trocar was used at first to reach the side of the tumor. Then, the disposable curved needle was used via the trocar. When the needle reached the tumor center, appropriate amount of ethanol was injected. For relatively large malignant liver tumors,multi-point injection was carried out for a better distribution of the ethanol injected throughout the masses. The curved needle was also used for treatment of the metastasis in retroperitoneal lymph nodes blocked by blood vessels and inaccessible by the straight needle.RESULTS: All of the 26 liver tumors received 2 or more times of successful PEI, through which ethanol was distributed throughout the whole tumor mass. Effect of the treatment was monitored by contrast-enhanced multi-phase CT and magnetic resonance imaging (MRI) examinations three months later. Of the 18 lesions whose diameters were smaller than 3 cm, the necrotic change across the whole mass and that in most areas were observed in 15 and 3 tumors,respectively. Among the 8 tumors sizing up to 3 cm, 5 were completely necrotic and 3 largely necrotic. Levels of tumor seromarkers were significantly reduced in some of the cases.In 5 patients with metastases of liver cancer in retroperitoneal lymph nodes who received 1 to 3

    In clinical radiology, there are numerous examples of new techniques that were initially enthusiastically promoted and then subsequently abandoned when early promise was not realized in routine patient care. Appropriateness of new or established interventional radiology techniques to specific clinical conditions must be determined from clinical experience, from communication with experts in the field and\\/or careful review of available medical literature, and on an individual patient basis by means of review of clinical notes and diagnostic imaging studies. For patients with liver neoplasms, regional techniques such as radiofrequency ablation (RFA) have been developed and are now the subject of ongoing research. This article describes the utilization of Evidence-Based Practice (EBP) techniques as a means of deciding the appropriateness of percutaneous RFA in treating colorectal liver metastases (CLM).

    Breast cancer patients typically develop brain metastases years after their initial diagnosis. During this clinical latency, cancer cells must evolve and adapt to the neural microenvironment to colonize. We hypothesized that breast cancer cells may assume brain-like properties to survive in the brain. Our results suggest that metastases overexpress many variables related to the γ-aminobutyric acid (GABA) and were able to proliferate by metabolizing GABA as a biosynthetic energy source. The ex...

  6. Selective internal radiation therapy (SIRT) for liver metastases secondary to colorectal adenocarcinoma

    International Nuclear Information System (INIS)

    Introduction: Selective internal radiation therapy (SIRT) is a relatively new commercially available microbrachytherapy technique for treatment of malignant hepatic lesions using 9Y embedded in resin microspheres, which are infused directly into the hepatic arterial circulation. It is FDA approved for liver metastases secondary to colorectal carcinoma and is under investigation for treatment of other liver malignancies, such as hepatocellular carcinoma and neuroendocrine malignancies. Materials/Methods: A modest number of clinical trials, preclinical animal studies, and dosimetric studies have been reported. Here we review several of the more important results. Results: High doses of beta radiation can be selectively delivered to tumors, resulting in impressive local control and survival rates. Ex vivo analyses have shown that microspheres preferentially cluster around the periphery of tumor nodules with a high tumor:normal tissue ratio of up to 200:1. Toxicity is usually mild, featuring fatigue, anorexia, nausea, abdominal discomfort, and slight elevations of liver function tests. Conclusions: Selective internal radiation therapy represents an effective means of controlling liver metastases from colorectal adenocarcinoma. Clinical trials have demonstrated improved local control of disease and survival with relatively low toxicity. Investigations of SIRT for other hepatic malignancies and in combination with newer chemotherapy agents and targeted biologic therapies are under way or in planning. A well-integrated team involving interventional radiology, nuclear medicine, medical oncology, surgical oncology, medical physics, and radiation oncology is essential for a successful program. Careful selection of patients through the combined expertise of the team can maximize therapeutic efficacy and reduce the potential for adverse effects

  7. Clinical results of mean GTV dose optimized robotic guided SBRT for liver metastases

    International Nuclear Information System (INIS)

    We retrospectively evaluated the efficacy and toxicity of gross tumor volume (GTV) mean-dose-optimized and real-time motion-compensated robotic stereotactic body radiation therapy (SBRT) in the treatment of liver metastases. Between March 2011 and July 2015, 52 patients were treated with SBRT for a total of 91 liver metastases (one to four metastases per patient) with a median GTV volume of 12 cc (min 1 cc, max 372 cc). The optimization of mean GTV dose was prioritized during treatment planning at the potential cost of planning target volume (PTV) coverage reduction while adhering to safe normal tissue constraints. The delivered median GTV biological effective dose (BED10) was 142.1 Gy10 (range, 60.2 Gy10 –165.3 Gy10) and the prescribed PTV BED10 ranged from 40.6 Gy10 to 112.5 Gy10 (median, 86.1 Gy10). We analyzed local control (LC), progression-free interval (PFI), overall survival (OS), and toxicity. Median follow-up was 17 months (range, 2–49 months). The 2-year actuarial LC, PFI, and OS rates were 82.1, 17.7, and 45.0 %, and the median PFI and OS were 9 and 23 months, respectively. In univariate analysis histology (p < 0.001), PTV prescription BED10 (HR 0.95, CI 0.91–0.98, p = 0.002) and GTV mean BED10 (HR 0.975, CI 0.954–0.996, p = 0.011) were predictive for LC. Multivariate analysis showed that only extrahepatic disease status at time of treatment was a significant factor (p = 0.033 and p = 0.009, respectively) for PFI and OS. Acute nausea or fatigue grade 1 was observed in 24.1 % of the patients and only 1 patient (1.9 %) had a side effect of grade ≥ 2. Robotic real-time motion-compensated SBRT is a safe and effective treatment for one to four liver metastases. Reducing the PTV prescription dose and keeping a high mean GTV dose allowed the reduction of toxicity while maintaining a high local control probability for the treated lesions

  8. PET-CT after radiofrequency ablation of colorectal liver metastases: Suggestions for timing and image interpretation

    International Nuclear Information System (INIS)

    Introduction. The main area of concern regarding radiofrequency ablation (RFA) of colorectal liver metastases is the risk of developing a local site recurrence (LSR). Reported accuracy of PET-CT in detecting LSR is high compared to morphological imaging alone, but no internationally accepted criteria for image interpretation have been defined. Our aim was to assess criteria for FDG PET-CT image interpretation following RFA, and to define a timetable for follow-up detection of LSR. Methods. Patients who underwent RFA for colorectal liver metastases between 2005 and 2011, with FDG-PET follow-up within one year after treatment were included. Results of repeat FDG-PET scans were evaluated until a LSR was diagnosed. Results. One hundred-seventy scans were obtained for 79 patients (179 lesions), 57 scans (72%) were obtained within 6 months of treatment. Thirty patients developed local recurrence; 29 (97%) within 1 year. Only 2% of lesions of <1 cm and 4% of <2 cm showed a LSR. Conclusion. The majority of local site recurrences are diagnosed within one year after RFA. Regular follow-up using FDG PET-CT within this period is advised, so repeated treatment can be initiated. Rim-shaped uptake may be present until 4–6 months, complicating evaluation. The benefit in the follow-up of lesions <2 cm may be limited

  9. Neuroendocrine liver metastases: Contributions of endoscopy and surgery to primary tumor search

    Neuroendocrine tumors (NETs) are diagnosed with increasing frequency and patients often present with liver metastases at the time of diagnosis.Apart from treatment of the metastases,resection of the primary tumor at an early phase is recommended to prevent complications,although it may be difficult to locate,especially in patients with functionally inactive NETs.Small and multifocal tumors in the jejunum and ileum represent a particular challenge.Primary hepatic neuroendocrine carcinoma is extremely rare and is diagnosed only after exclusion of other primary tumors.Therefore,some uncertainty may remain,as small non-hepatic primary tumors may escape detection.Diagnostic work-up in these patients includes biochemical assays and imaging modalities (also comprising specific techniques of scintigraphy and positron emission tomography).This editorial highlights the contributions of endoscopy and operative exploration to the search for the primary tumor.Besides esophagogastro-duodenoscopy,endoscopic ultrasonography,colonoscopy and bronchoscopy,special endoscopic techniques such as balloon enteroscopy or capsule endoscopy are used with growing experience.Compared with balloon enteroscopy,capsule endoscopy is noninvasive and better tolerated,but it cannot localize a lesion precisely and does not allow biopsy or removal of lesions.Before proceeding to surgery,a discussion of the findings by a tumor board should be a standard procedure.Improvements in diagnostic tools have created new perspectives for the detection of obscure primary tumors in patients with neuroendocrine liver metastases,and these searches are best coordinated by a multidisciplinary team.

  11. Brain metastases in lung cancer. Impact of prognostic factors on patient survival

    International Nuclear Information System (INIS)

    Background. Brain metastases are common patterns of dissemination in lung cancer patients. In this paper we would like to assess the pattern of brain metastases in lung cancer patients and the impact of prognostic factors on the survival of lung cancer patients with brain metastases. Patients and methods. In the year 1998 there were 974 registered patients with lung cancer in Slovenia, six hundred and fifteen of them were treated at the Institute of Oncology Ljubljana and we analyzed them. Among 615 patients 137 (22.3 %) of them have had brain metastases during a natural course of disease. Results. For 12 patients presenting with solitary brain metastases (most of them were undertaken metastasectomy) median survival was 7.6 months, while in patients with multiple brain metastases the median survival was 2.8 months (p 0.0018). Of the 137 patients 45 (32.8 %) were small cell lung cancer patients, 43 (31.4 %) were adenocarcinoma patients and 19 (13.9 %) were squamous cell carcinoma patients. Patients with performance status (WHO scale) less than 2 had the median survival time 3.7 months while patients with performance status 2 or more had median survival time 2.7 moths (p=0.0448). Conclusions. Patients with solitary brain metastases had better survival comparing with those who had multiple metastases. It is surprisingly that the portion of brain metastases patients with adenocarcinoma is almost equal to those with small-call lung cancer therefore, the prophylactic cranial radiation becomes actual for both groups of patients. The performance status of patients with brain metastases remains very important prognostic factor. (author)

  12. Use of Yttrium-90 Microspheres in the Treatment of Unresectable Hepatic Metastases From Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: Therapy for patients with unresectable liver metastases from breast cancer that were refractory to multiple treatment regimens was performed using radioactive microspheres. High doses of radiation were delivered to tumors from these permanently implanted yttrium-90 (90Y) microspheres, delivered through the hepatic arterial vessels. Methods and Materials: Women from three institutions were selected for treatment, after screening that demonstrated vascular access to all tumors and after imaging confirmed that microspheres would be implanted only in the liver tumors. All patients were followed with laboratory and imaging studies at regular intervals until death. Toxicities, both acute and late were recorded, and actuarial survival determined. Results: A total of 44 women were treated from April 2002 to April 2005. Median follow-up of these women was 14 months (1-42 months). No treatment-related procedure deaths or radiation related veno-occlusive liver failures were found. Computed tomographic imaging partial response was 47% and positron emission tomographic response 95%. Conclusion: In this group of heavily pretreated patients, radioactive microspheres produced an encouraging median survival, with acceptable toxicity and a significant objective response rate, suggesting that further investigation of this approach is warranted

    The biology of colorectal cancer differs according to itsitss location within the large intestine. A report publishedinpublished inin a previous issue of World Journal of Gastroenterology (November 2010) evaluated the importance of tumor location as a risk factor for lymph node metastasis in colorectal cancer, and showed that rectal cancer is prone to metastasize to lymph nodes as compared with colon cancer. However, in order to conclude that the tumor location is independently associated with the occurrence of lymph node metastasis, it is necessary to consider a selection bias or other patient- and tumor-related factors carefully.

  17. Influence of different fasting periods on P-31-MR-spectroscopy of the liver in normals and patients with liver metastases

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the influence of different fasting periods on the in vivo P-31MR spectroscopy of the healthy liver and patients with liver metastases. Image-guided localized P-31-MRS was performed in 24 patients with liver metastases and in 20 healthy volunteers. The spectra were obtained with a whole body scanner operating at 1.5 T using a surface coil. The P-31-MRS was performed after a fasting period of 3-5 h (group 1) and after overnight fasting (group 2). The PME/β-NTP, PDE/β-NTP and Pi/β-NTP were calculated from P-31-MR spectra and were compared in relation to the nutrition status of the volunteers and patients. The PME/β-NTP and PDE/β-NTP were significantly increased in spectra of patients with metastases. There were no significant changes in the ratios of phosphorus metabilites in healthy liver tissue or in liver metastases after a fasting period of 3-5 h as compared with overnight fasting. (orig.)

    Full Text Available BACKGROUND: Brain metastases occur commonly in patients with lung cancer. Small vessel ischemic disease is frequently found when imaging the brain to detect metastases. We aimed to determine if the presence of small vessel ischemic disease (SVID of the brain is protective against the development of brain metastases in lung cancer patients. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort of 523 patients with biopsy confirmed lung cancer who had received magnetic resonance imaging of the brain as part of their standard initial staging evaluation was reviewed. Information collected included demographics, comorbidities, details of the lung cancer, and the presence of SVID of the brain. A portion of the cohort had the degree of SVID graded. The primary outcome measure was the portion of study subjects with and without SVID of the brain who had evidence of brain metastases at the time of initial staging of their lung cancer.109 patients (20.8% had evidence of brain metastases at presentation and 345 (66.0% had evidence of SVID. 13.9% of those with SVID and 34.3% of those without SVID presented with brain metastases (p<0.0001. In a model including age, diabetes mellitus, hypertension, hyperlipidemia, and tobacco use, SVID of the brain was found to be the only protective factor against the development of brain metastases, with an OR of 0.31 (0.20, 0.48; p<0.001. The grade of SVID was higher in those without brain metastases. CONCLUSIONS/SIGNIFICANCE: These findings suggest that vascular changes in the brain are protective against the development of brain metastases in lung cancer patients.

    Grade 3 (G3) gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) are rare, and there is no report specifically dealing with patients of liver metastases from G3 GEP NETs.From January 2004 to January 2014, 36 conservative patients with G3 GEP NET liver metastases were retrospectively identified from 3 hepatobiliary centers in China. The clinical features and treatment outcomes were analyzed.Aggressive locoregional treatments (LT, including cytoreductive surgery, radiofrequency ablation, and liver-directed intra-arterial intervention) and systemic therapy (ST) were introduced separately or combined, with 26 (72%) patients receiving resection of primary tumor and/or hepatic metastases, 12 patients receiving non-surgical locoregional interventions (NSLRIs), and 22 patients receiving certain kind of STs. Median overall survival (OS) was 20.0 months (95% confidence interval [CI]: 8.9-31.1 months) and survival rates were 62.6%, 30.1%, and 19.8%, at 1, 3, and 5 years, respectively. The median OS was 9.0 months (95%CI: 3.3-14.7 months) for patients receiving only STs (n = 6), 19 months (95%CI: 1.3-36.8 months) for patients receiving LT followed by STs (n = 16), and 101 months (95%CI: 0.0-210.2 months) for patients receiving only LT (n = 12). Moreover, compared with those receiving only ST or best supportive care, patients given certain types of LTs had higher rates of symptom alleviation (3/8 versus 20/23). On univariate analysis, positive prognostic factors of survival were pancreatic primary tumor (P = 0.013), normal total bilirubin level (P = 0.035), receiving surgery (P = 0.034), receiving NSLRI (P = 0.014), and sum of diameters of remnant tumor consolidate these results, and to discover the most appropriate seletion criteria for patients to undergo different kinds of aggressive LTs and to find the most effective combinations, with or without ST.

    Primary liver cancer (hepatocellular carcinoma, or HCC) is associated with liver cirrhosis 60-80% of the time. Liver cancer is one of the most common malignancies in the world, with approximately 1,000,000 cases reported every year. About 80% of people with primary liver cancer are male. Although two-thirds of people have advanced liver disease when they seek medical help, one third of the patients have cancer that has not progressed beyond the liver. HCC may metastasize to the lung, bones, kidney, and many other organs. Surgical resection, liver transplantation, chemotherapy and radiation therapy are the foundation of current HCC therapies. However the outcomes are poor: the survival rate is almost zero for metastatic HCC patients. Molecular mechanisms of HCC metastasis need to be understood better and new therapies must be developed to selectively target to unique characteristics of HCC cell growth and metastasis. We have developed the "in vivo microscopy" to study the mechanisms that govern liver tumor cell spread through the microenvironment in vivo with real-time confocal near-infrared fluorescence imaging. A recently developed "in vivo flow cytometer" and optical imaging are used to assess liver tumor cell spreading and the circulation kinetics of liver tumor cells. A real- time quantitative monitoring of circulating liver tumor cells by the in vivo flow cytometer will be useful to assess the effectiveness of the potential therapeutic interventions.

  3. Resin 9Y-microsphere brachytherapy for unresectable colorectal liver metastases: Modern USA experience

    International Nuclear Information System (INIS)

    Purpose: Salvage therapy for patients with unresectable colorectal liver metastases that were refractory to oxaliplatin and irinotecan was performed via radioactive microspheres. High doses of radiation were delivered to tumors from permanently implanted 9Y microspheres, delivered through the hepatic arterial vessels. Methods and Materials: Patients from 7 institutions were selected for treatment after screening-defined vascular access to all the tumors, and imaging-confirmed microspheres would be implanted only in the liver tumors. All patients were followed with laboratory and imaging studies at regular intervals until death. Toxicities, both acute and late, were recorded, and actuarial survival determined. Results: A total of 208 patients were treated from April 2002 to April 2005. Median follow-up of the 129 men and 79 women is 13 months (range, 1-42 months). Median survival is 10.5 months for responders but only 4.5 months in nonresponders. No treatment-related procedure deaths or radiation-related venoocclusive liver failures were found. Computed tomography partial response was 35%; positron emission tomography response of 91% and reduction in carcinoembryonic antigen of 70% were achieved. Conclusions: In this group of heavily pretreated patients, radioactive microspheres produced an encouraging median survival, with acceptable toxicity, and a significant objective response rate, which suggests that further investigation of this approach is warranted

  4. Computer assisted early detection of liver metastases from fMRI maps

    International Nuclear Information System (INIS)

    We present a new method for computer-aided early detection of liver metastases tumors. The method characterized colorectal hepatic metastases and follows their early hemodynamical changes using an fMRI-based statistical model. The changes in hepatic hemodynamics are evaluated from T2W fMRI images acquired during breathing of air, air-CO2, and carbogen. A classification model is build to help radiologists differentiate tumor from healthy tissue. The model is built from 132 well-validated fMRI samples of tumors and healthy tissue. For each sample, a histogram-based features-vector is constructed. The model is then generated from the data with an SVM classifier. To test the model, 32 non-validated fMRI samples were used. A total of 22 samples proved to be healthy tissue and 11 samples proved to be tumors. Nine samples were judged as tumors by the naked eye, but proved to be healthy tissue later. Our classification model yields accuracy of 78.12% with 66.67% precision on the test set. (orig.)

  8. Stereotactic Radiotherapy for Brain metastases from 152 lung cancer patients

    International Nuclear Information System (INIS)

    Objective: To assess the clinical efficacy and prognostic factors of Stereotactic Radiotherapy (SRT) for patients with brain metastases (BM) from lung cancer. Methods: From March 1995 to July 2006, 152 consecutive patients with BM from lung cancer were treated by SRT, among them,59 patients received SRT alone, 40 patients received SRT plus whole brain radiotherapy (SRT + WBRT), and 53 patients were salvaged by SRT after WBRT (salvaged group). Log-rank method was used for univariate analyses. Cox regression model was used for multivariate analyses. Results: The follow-up rate was 97.4%. The half year and 1 year local control rate for SRT alone group, SRT + WBRT group and salvage group were 96. 0% and 93.4%, 94.2% and 90.8%, 81.7% and 77.5% (χ2 = 5.39, P = 0.068)respectively. The 1-, 2-, 5 year survival rate for SRT alone group, SRT + WBRT group and salvage group were 47.4%, 23.7%, 8.5%; 55.0%, 20.0%, 0%; 41.5%, 7.5%, 1. 9%, respectively. The median overall survival or each group was 11, 12, 11 months (χ2 = 4.08, P = 0130). The univariate analysis showed that the interval between diagnosis of lung cancer and BM, KPS, thoracic surgery, GPA grade, RPA class, system disease stable were significant prognostic factors (χ2 =11.97, 5.91, 15.48, 14.48, 15.86, 17.36, P = 0.001, 0.015, 0.000, 0.000, 0.000, 0.000). The multivariate analysis showed that the RPA class , thoracic surgery were the independent prognostic factors (χ2 = 21.02, 8.18, P = 0.000, 0.004). KPS score less than 70, 80 ,90 for all patients before SRT and 3 months later after SRT were 48.7%, 33.6%, 17.8% and 27.0%, 46.7%, 26.3% respectively (t = 7.16, P=0.000). Conclusions: A definitive benefit of SRT in the treatment BM from lung cancer is observed; there is no difference of survival among SRT alone, SRT + WBRT and salvage treatment. SRT can improve the patients' KPS score. Thoracic surgery, RPA class were the independent prognostic factors for patients with BM from lung cancer. (authors)

  10. Upfront systemic chemotherapy and preoperative short-course radiotherapy with delayed surgery for locally advanced rectal cancer with distant metastases

    International Nuclear Information System (INIS)

    Choosing the most effective approach for treating rectal cancer with mesorectal fascia (MRF) involvement or closeness and synchronous distant metastases is a current clinical challenge. The aim of this retrospective study was to determine if upfront systemic chemotherapy and short-course radiotherapy (RT) with delayed surgery enables R0 resection. Between March 2009 and October 2009, six patients were selected for upfront chemotherapy and short-course RT (5 × 5 Gy) with delayed surgery. The patients had locally advanced primary tumors with MRF involvement or closeness, as well as synchronous and potentially resectable distant metastases. Chemotherapy was administered to five patients between the end of the RT and surgery. All patients underwent total mesorectal excision (TME). The median patient age was 54 years (range 39-63). All primary and metastatic lesions were resected simultaneously. The median duration between short-course RT and surgery was 13 weeks (range, 7-18). R0 resection of rectal lesions was achieved in 5 patients. One patient, who had a very low-lying tumor, had an R1 resection. The median follow-up duration for all patients was 16.7 months (range, 15.5-23.5). One patient developed liver metastasis at 15.7 months. There have been no local recurrences or deaths. Upfront chemotherapy and short course RT with delayed surgery is a valuable alternative treatment approach for patients with MRF involvement or closeness of rectal cancer with distant metastases

    Since liver cancer seriously threatens human health, it is very urgent to explore an effective method for diagnosing liver cancer early. In this study, we investigated the structure differences of IR spectra between neoplastic liver cells and normal liver cells. The major differences of absorption bands were observed between liver cancer cells and normal liver cells, the values of A2955/A2921, A1744/A1082, A1640/A1535, H1121/H1020 might be potentially useful factors for distinguishing liver cancer cells from normal liver cells. Curve fitting also provided some important information on structural differences between malignant and normal liver cancer cells. Furthermore, IR spectra combined with hierarchical cluster analysis could make a distinction between liver cancer cells and normal liver cells. The present results provided enough cell basis for diagnosis of liver cancer by FTIR spectroscopy, suggesting FTIR spectroscopy may be a potentially useful tool for liver cancer diagnosis.

    Abstract Circulating tumor cells (CTCs) released from a periampullary or pancreatic cancer can be more frequently detected in the portal than the systemic circulation and potentially can be used to identify patients with liver micrometastases. Aims of this study is to determine if CTCs count in portal venous blood of patients with nonmetastatic periampullary or pancreatic adenocarcinoma can be used as a predictor for subsequent liver metastases. CTCs were quantified in portal and peripheral venous blood samples collected simultaneously during pancreaticoduodenectomy in patients with presumed periampullary or pancreatic adenocarcinoma without image-discernible metastasis. Postoperatively patients were monitored for liver metastasis by abdominal magnetic resonance imaging or computed tomography every 3 months for 1 year. Sixty patients with a pathological diagnosis of periampullary or pancreatic adenocarcinoma were included in the study. Multivariate analysis indicated that portal CTC count was a significant predictor for liver metastases within 6 months after surgery. Eleven of 13 patients with a high portal CTCs count (defined as >112 CMx Platform estimated CTCs in 2 mL blood) developed liver metastases within 6 months after surgery. In contrast, only 6 of 47 patients with a low portal CTC count developed liver metastases (P < 0.0001). A value of 112 CMx Platform estimated CTCs had 64.7% sensitivity and 95.4% specificity to predict liver metastases within 6 months after surgery. We concluded that a high CTC count in portal venous blood collected during pancreaticoduodenectomy in patients with periampullary or pancreatic adenocarcinoma without metastases detected by currently available imaging tools is a significant predictor for liver metastases within 6 months after surgery.

  16. Liver-first approach of colorectal cancer with synchronoushepatic metastases: A reverse strategy

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Recently, there has been a change in the strategy ofhow synchronous colorectal hepatic metastases areattributed to the development of more valuable protocolsof chemotherapy and radiotherapy for neoadjuvanttreatment of colorectal neoplasms and their hepaticmetastases. There is a consensus that patients withsynchronous colorectal hepatic metastases have lowersurvival than those with metachronous colorectal hepaticmetastases. Currently, controversy remains concerningthe best approach is sequence in a patient withcolorectal cancer and synchronous hepatic metastasesresection. To obtain a better patient selection, theauthors have suggested the initial realization of systemicchemotherapy in the circumstance of patients withcolorectal tumor stage Ⅳ, since these patients have asystemic disease. The rationale behind this liver-firststrategy is initially the control of synchronous hepaticmetastases of colorectal carcinoma, which can optimizea potentially curative hepatic resection and longstandingsurvival. The liver-first strategy procedure is indicatedfor patients with colorectal hepatic metastases whorequire downstaging therapy to make a curative liverresection possible. Thus, the liver-first strategy isconsidered an option in cases of rectal carcinoma in theearly stage and with limited or advanced synchronouscolorectal hepatic metastases or in case of patientswith asymptomatic colorectal carcinoma, but withextensive liver metastases. Patients undergoing systemicchemotherapy and with progression of neoplasticdisease should not undergo hepatic resection, becauseit does not change the prognosis and may even makeit worse. To date, there have been no randomizedcontrolled trials on surgical approach of colorectalsynchronous hepatic metastases, despite the relativelyhigh number of available manuscripts on this subject.All of these published studies are observational, usuallyretrospective, and often non-comparative.

    Abstract Background Preliminary experimental studies have suggested that the in situ destruction of tumor tissue by local laser ablation (LA) may also stimulate host immunity against cancer. We investigated local and systemic induction of immune responses after laser ablation in the setting of residual tumor. Methods A murine colorectal cancer (CRC) liver metastasis model was used. Selected tumors of liver CRC bearing mice and livers of mice without tumor induction were treated with LA. Liver...

    Metastatic breast cancer is a heterogeneous disease, commonly affecting the liver. We report our experience with {sup 90}Y radioembolisation (RE) and its effects on the survival of patients with treatment-refractory breast cancer liver metastases. A total of 77 female patients affected by breast cancer were accepted into our department for RE. Inclusion criteria were inoperable and chemotherapy-refractory hepatic metastases, acceptable performance status, sufficient residual liver, no significant hepato-pulmonary shunts. Patients were divided in two groups: group 1 (29 patients) included those with Eastern Cooperative Oncology Group (ECOG) score 0, liver involvement (0-25 %) and no extrahepatic disease (EHD); group 2 (23 patient) included patients with ECOG score 1-2, liver involvement (26-50 %) and evidence of EHD. A total of 25 patients were considered ineligible. The median age of the remaining 52 patients was 57.5 years. The median overall survival was 11.5 months and better in those whose performance status and liver function were preserved (14.3 versus 8.2 months). According to Response Evaluation Criteria in Solid Tumor (RECIST), partial response (PR) was achieved in 29 patients (56 %), stable disease (SD) was achieved in a further 18 patients (35 %) and 5 patients showed progressive disease (PD) (10 %). {sup 90}Y RE is effective in the treatment of liver metastases from breast cancer. We demonstrated a relevant survival and encouragingly high response rate in patients with treatment-refractory disease. (orig.)

    AIM: To compare the diagnostic accuracy of single section spiral computed tomography (CT) and magnetic resonance imaging (MRI) with tissue-specific contrast agent mangafodipir trisodium (MnDPDP) in the detection of colorectal liver metastases. MATERIAL AND METHODS: One hundred and twenty-five consecutive patients undergoing surgery for primary and/or metastatic disease were evaluated using CT (5 mm collimation and reconstruction interval, pitch 2), two-dimensional fast spoiled gradient echo (2D FSPGR) T1 and single shot fast-spin echo (SSFSE) T2 weighted breath-hold MRI sequences, performed before and after intravenous administration of MnDPDP. The reference standards were intraoperative ultrasound and histology. RESULTS: The per-patient accuracy of CT was 72.8 versus 78.4% for unenhanced MRI (p=0.071) and 82.4% for MnDPDP-enhanced MRI (p=0.005). MnDPDP-enhanced MRI appeared to be more accurate than unenhanced MRI but this was not significant (p=0.059). The sensitivity of CT was 48.4% versus 58.1% for unenhanced MRI (p=0.083) and 66.1% for MnDPDP-enhanced MRI (p=0.004). The difference in specificity between procedures was not significant. The per-lesion sensitivity was 71.7, 74.9 and 82.7% for CT, unenhanced MRI, and MnDPDP-enhanced MRI, respectively; the positive predictive value of the procedures was respectively 84.0, 96.0 and 95.8%. MnDPDP-enhanced MRI provided a high level diagnostic confidence in 92.5% of the cases versus 82.5% for both unenhanced MRI and CT. The kappa value for inter-observer variability was >0.75 for all procedures. CONCLUSIONS: The diagnostic accuracy and sensitivity of MnDPDP-enhanced MRI is significantly higher than single section spiral CT in the detection of colorectal cancer liver metastases; no significant difference in diagnostic accuracy was observed between unenhanced MRI and MnDPDP-enhanced MRI.

    We conducted a large, multicenter, retrospective survey aimed to explore the impact of tumor bone involvement in Non-Small Cell Lung Cancer.Data on clinical-pathology, skeletal outcomes and bone-directed therapies for 661 deceased patients with evidence of bone metastasis were collected and statistically analyzed. Bone metastases were evident at diagnosis in 57.5% of patients. In the remaining cases median time to bone metastases appearance was 9 months. Biphosphonates were administered in 59.6% of patients. Skeletal-related events were experienced by 57.7% of patients; the most common was the need for radiotherapy. Median time to first skeletal-related event was 6 months. Median survival after bone metastases diagnosis was 9.5 months and after the first skeletal-related event was 7 months. We created a score based on four factors used to predict the overall survival from the diagnosis of bone metastases: age >65 years, non-adenocarcinoma histology, ECOG Performance Status >2, concomitant presence of visceral metastases at the bone metastases diagnosis. The presence of more than two of these factors is associated with a worse prognosis.This study demonstrates that patients affected by Non-Small Cell Lung Cancer with bone metastases represent a heterogeneous population in terms of risk of skeletal events and survival.

    Distant metastases of differentiated thyroid cancer are unusual; lung and bones are the most frequently affected sites. Soft tissue metastases (STM) are extremely rare. We describe two cases of patients with differentiated thyroid cancer metastasizing to soft tissues. Both patients had widespread metastatic disease; clinically asymptomatic soft tissue metastases were found by 18-Fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F FDG PET-CT), and confirmed by cytological and/or histopathological studies. These findings underscore the ability of {sup 18}F FDG PET-CT in accurately assessing the extent of the disease, as well as the utility of the method to evaluate regions of the body that are not routinely explored.

  4. Evaluation of true diffusion, perfusion factor, and apparent diffusion coefficient in non-necrotic liver metastases and uncomplicated liver hemangiomas using black-blood echo planar imaging

    International Nuclear Information System (INIS)

    Purpose: To assess the added value of true diffusion (D), perfusion factor (f) and apparent diffusion coefficient at low b-values (ADClow) for differentiation between liver metastases and hemangiomas based on respiratory-triggered high-resolution Black-Blood Single-Shot SpinEcho Echo Planar Imaging (BB SS SE-EPI). Materials and methods: Twenty-five patients suspected for malignant colorectal liver lesions were included in this study. A total of 106 lesions were examined. Different b-value images were compared for lesion conspicuity, image quality and artifacts using rank order statistic (RIDIT) and Student's t-test. D, f, and ADClow values were calculated. Pearson correlation coefficient is used for comparison of interobserver variability. Results: Best lesion conspicuity (p 2); best image quality (p 2. Image artifacts were lowest (p 2. Over the whole sample, D in metastases (Dmet) was significantly (p hem); f and ADClow of metastases (fmet, respectively, ADClowmet) were significantly (p low of hemangiomas (fhem, respectively, ADClowhem). All Pearson correlations were statistically significant at a 0.01 level. Conclusions: This preliminary study shows the potential of BB SS SE-EPI as a useful technique to aid in differentiating between liver metastasis and hemangioma. The calculation of D, f and ADClow provides useful additional information for differentiating metastases from hemangiomas

  10. Lobulated Enhancement Evaluation in the Follow-Up of Liver Metastases Treated by Stereotactic Body Radiation Therapy

    International Nuclear Information System (INIS)

    Objective: The Response Evaluation Criteria in Solid Tumors (RECIST) can have limitations when used to evaluate local treatments for cancer, especially for liver malignancies treated by stereotactic body radiation therapy (SBRT). The aim of this study was to validate the relationship between the occurrence of lobulated enhancement (LE) and local relapse and to evaluate the utility of this relationship for predicting local progression. Patients and Methods: Imaging data of 59 lesions in 46 patients, including 281 computed tomographic (CT) scans, were retrospectively and blindly reviewed by 3 radiologists. One radiologist measured the lesion size, for each CT and overall, to classify responses using RECIST threshold criteria. The second studied LE occurrence. A third radiologist was later included and studied LE occurrence to evaluate the interobserver consistency for LE evaluation. Results: The mean duration of follow-up was 13.6 months. LE was observed in 16 of 18 progressive lesions, occurring before size-based progression in 50% of cases, and the median delay of LE detection was 3.2 months. The sensitivity of LE to predict progression was 89%, and its specificity was 100%. The positive predictive value was 100%, the negative predictive value was 95.3%, and the overall accuracy was 97%. The probability of local progression-free survival at 12 months was significantly higher for lesions without LE compared with all lesions: 0.80 (CI 95%: 0.65-0.89) versus 0.69 (CI 95%: 0.54-0.80), respectively. The overall concordance rate between the 2 readers of LE was 97.9%. Conclusion: Response assessment of liver metastases treated by SBRT can be improved by including LE. This study demonstrates the diagnostic and predictive utility of LE for assessing local progression at a size still eligible for local salvage treatment

    AIM: To analyze the risk factors for interval time,number and pattern of hepatic metastases from gastric cancer after radical gastrectomy, and provide evidence for predicting and preventing hepatic metastasis from gastric cancer after radical gastrectomy. METHODS: A retrospective study of 87 patients with hepatic metastasis who underwent radical gastrectomy for gastric cancer from 1996 to 2001. The data was analyzed to evaluate significant risk factors for interval time, number and pattern of hepatic metastases originating from gastric cancer after radical gastrectomy.RESULTS: The size of gastric cancer and lymph node metastases were independently correlated with the interval time of hepatic metastases; the depth of invasion was independently correlated with the number of hepatic metastases; while the depth of invasion and Lauren classification were independently correlated with the pattern of hepatic metastases.CONCLUSION: We evaluated the interval time of hepatic metastases with the size of gastric cancer and lymph node metastases. The depth of invasion could be used to evaluate the number of hepatic metastases, while the depth of invasion and the Lauren classification could be used to evaluate the pattern of hepatic metastases in patients who underwent radical gastrectomy.

    The treatment of lymph node metastases involving the carotid artery is controversial. The aim of the present study was to determine the outcomes of head and neck cancer patients with radiographic carotid artery involvement in neck metastases. A total of 27 patients with head and neck cancer and radiologically diagnosed advanced metastases involving the common carotid artery or internal carotid artery were enrolled. All patients underwent a primary or salvage neck dissection and surgical carotid peeling. The oncological outcome and survival of all patients were analyzed. Loco-regional control was observed in 13 of the 27 patients (48.1%). During follow-up, five patients (18.5%) developed second primaries and 11 (40.7%) developed distant metastases. The survival time was poor independent of regional control. The median overall survival was 1.55 years and disease-free survival was 0.71 year. Radiographic carotid artery involvement in neck metastases in head and neck cancer appears to correlate with a poor long-term prognosis, with a high rate of distant metastases despite loco-regional control.

    2015-03-01

    Full Text Available Background: Small cell lung cancer is an aggressive subtype of lung cancer whereby about one-third of cases are complicated with bra­in metastases. However, cerebellar metastases are uncommon and contribute to less than 10% of brain metastases. Case: We report a 76-year-old Malay male, an active smoker who presented with dyspnea and occasional cough with hemoptysis for one week. He also pre­sented with headache and constitutional symptoms of malignancy. Clinical examination suggested the presence of right upper chest patholo­gy and positive left cerebellar signs. His condition deteriorated two days later and he passed away after failed attempts at resuscitation. Chest radiograph showed right upper lobe collapse, and brain magnetic resonance imaging showed metastatic lesion in the left cerebellum extending to the right cerebellum. Post-mortem findings revealed small cell lung cancer with cerebellar metastases. Conclusion: Small cell lung cancer patients with brain metastases deteriorate very rapidly, and the management is mainly supportive. Primary prevention through education is the best way to reduce the incidence of lung cancer. In addition, secondary prevention and screening should be undertaken at earlier stages of the disease, as some studies have shown that combined chemotherapy and radiotherapy improve prog­nosis of malignancies detected at early stage.

    The enzyme gamma-glutamyltransferase (GGT) is frequently overexpressed in cancer cells and tissues and has significant utility as a cancer marker. Significant heterogeneity of the enzyme has been described due to both transcriptional and post-translational variations. For possible use in diagnosis and follow-up of patients with colorectal cancer, a search was performed for specific mRNA subtypes and glycan structures of the enzyme in liver metastases. We found no differences in the distribution of three GGT mRNA subtypes (fetal liver, HepG2, placenta) in metastatic tissue and normal liver tissue. Furthermore, the three subtypes were present in leukocytes isolated from both normal individuals and cancer patients. Two colon carcinoma cell lines (Colo 205 and HCC 2998) also displayed the three forms and no consistent changes in mRNA composition were noted after butyrate-induced differentiation of the cells. Thus, neither of the GGT mRNA subforms appear to be tumor-specific, although some qualitative and quantitative variations were noted. Two distinct glycosylation features were detected for GGT in metastatic tissue in contrast to normal liver GGT; an extreme sialic acid heterogeneity and a significant increase in beta1,6GlcNAc branching. The GGT glycans from the two colon carcinoma cell lines also possessed these features. As butyrate treatment of the cells resulted in an increased sialic acid content and a reduced beta1,6GlcNAc branching, the described carbohydrate structures appear to be part of a tumor-related pattern. We were, however, unable to identify such GGT isoforms in serum from patients with advanced colorectal cancer. This indicates that their usefulness in diagnostic use is doubtful. PMID:12758164

  2. Results of radioiodine therapy in patients with pulmonary metastases of differentiated thyroid cancer

    International Nuclear Information System (INIS)

    Factors affecting the effect of 131I treatment and survival after pulmonary metastases in patients with differentiated thyroid cancer, were studied. Between 1984-1999, pulmonary metastases was observed in 51 out of 153 patients with differentiated thyroid cancer at our institution. Of these 41 patients had papillary and 10 follicular thyroid cancer. There were 37 females and 14 males with mean age (±S.D.) of 50.5±19.0 years. These 51 patients were subjected to 131I therapy. The effect of 131I treatment and the prognostic values of the following variables were examined: sex, age at the time of 131I treatment, histologic type of cancer, size of pulmonary metastases on CT, total-body scintigraphy with 201Tl and 131I, serum thyroglobulin levels and presence of metastases in distant sites other than lung. The effect of 131I treatment was evaluated by means of changes in the number and size of metastatic shadows on chest CT and by serum thyroglobulin levels. The minimum duration of follow-up was 12 months. Therapeutic 131I dose scans revealed detectable uptake in 25 of 51 patients. Therapeutic 131I dose uptake was achieved more frequently in patients under 40 years of age and in those with follicular cancers. Of the 51 patients, 13 were evaluated to be treated successfully. Those under 40 years of age, with 131I up-take in the lung and presence of other metastases showed a good response to treatment than others. Follicular cancer showed a more significant association with coarse type of lung metastases (>5 mm in diameter on chest CT) and good 131I uptake than papillary cancer. Of all the variables studied, the best prognosis for survival was demonstrated by increased 131I uptake in pulmonary metastases. These results indicate that age, 131I uptake and presence of other metastases are important factors in predicting the effect of 131I treatment for pulmonary metastases of differentiated thyroid cancer.

  3. Radiation therapy for brain metastases from breast cancer by histological classification

    International Nuclear Information System (INIS)

    One hundred thirteen patients with metastatic brain tumor from breast cancer who were treated with external irradiation between 1989 and 1997 at Cancer Institute Hospital were studied. The patients were all histopathologically proven to have invasive ductal carcinoma (scirrhous type 54 cases, papillotubular type 18, solid-tubular type 41). The patients were evaluated for efficacy and histopathological subtypes. The time interval between the diagnosis of breast cancer and brain metastases was 53.6 months for the scirrhous type, 75.0 months for the papillotubular type, and 35.5 months for the solid-tubular type. The time interval between the diagnosis of initial distant metastases and brain metastases was 14.3 months for the scirrhous type, 22.5 months for the papillotubular type, and 12.5 months for the solid-tubular type. Efficacy rates (CR+PR) for external irradiation of the brain metastases were 40.0% for the scirrhous type, 66.7% for the papillotubular type, and 36.6% for the solid-tubular type. The papillotubular type had a favorable efficacy rate compared with the other two types. Median survival time (MST) from the start of treatment for brain metastases and one-year survival rate were 5 months and 11.1% for the scirrhous type, 7 months and 41.5% for the papillotubular type, and 4 months and 28.3% for the solid-tubular type, respectively. No statistically significant difference between survival rates was observed among the histopathological types. Univariate analysis showed performance status, number of metastatic tumors, and existence of extracranial metastases without bony metastasis to be significantly related to prognosis. Multivariate analysis showed only extracranial metastases without bony metastases to be related to prognosis. (author)

  4. Electrochemotherapy of colorectal liver metastases - an observational study of its effects on the electrocardiogram

    Science.gov (United States)

    2015-01-01

    Background Electrochemotherapy (ECT) is a combined treatment in which high voltage electroporation (EP) pulses are used to facilitate the uptake of a chemotherapeutic drug into tumor cells, thus increasing antitumor effectiveness of the drug. The effect of ECT of deep-seated tumors located close to the heart on functioning of the heart has not been previously investigated. In this study, we investigate the effects of intra-abdominal ECT of colorectal liver metastases on functioning of the heart during the early post-operative care period. Methods For ECT high voltage EP pulses with amplitudes of up to 3000 V and 30 A were delivered in synchronization with electrical activity of the heart. Holter electrocardiographic (ECG) signals were obtained from 10 patients with colorectal liver metastases treated with ECT. ECG was recorded during the periods of 24 hours before and after the surgical procedure involving ECT. Four-hour long night-time ECG segments from both periods exhibiting the highest level of signal stationarity were analyzed and compared. Changes in several ECG and heart rate variability (HRV) parameters were evaluated. Results No major heart rhythm changes (i.e., induction of extrasystoles, ventricular tachycardia or fibrillation) or pathological morphological changes (i.e., ST segment changes) indicating myocardial ischemia were found. However, we found several minor statistically significant but clinically irrelevant changes in HRV parameters after ECT procedures: a decrease in median values of the mean NN interval, a decrease in the low-frequency and in the normalized low-frequency component, and an increase in the normalized high-frequency component. Conclusions Only minor effects of intra-abdominal ECT treatment on functioning of the heart were found. They were expressed as statistically significant but clinically irrelevant changes in heart rate and long-term HRV parameters and were as such not life-threatening to the patients.

    Of ophthalmic involvement from metastatic breast cancer, extraocular/intraorbital metastases are extremely rare. External beam radiotherapy has been a mainstay palliation for symptomatic orbital metastases. We present a case of bilateral orbital metastases from breast cancer successfully treated with stereotactic radiotherapy (SRT). A 38-year-old woman presented with decreased vision in the right eye for 3 weeks. Eight months previously, she underwent whole-brain radiotherapy for multiple brain metastases from breast cancer. Visual acuity was hand motion, and the eyelid closed incompletely in the affected eye. Computed tomography scans showed a 3-cm extraconal mass in the right orbit. She underwent temporary tarsorrhaphy followed by SRT. A total dose of 39 Gy was delivered to the right orbital mass in three daily fractions. Four months later, her visual function was normal in both eyes and the right orbital mass disappeared. A new lesion was detected in the left orbit. She underwent SRT for the left orbital lesion using the same dose-fractionation schedule. No radiation-related toxicities were observed. She died 19 months after the first SRT. Our case suggests that SRT may be an effective and safe treatment option in patients with orbital metastases from breast cancer. PMID:21999613

  10. Intracranial arterial infusion chemotherapy for lung cancer complicated by brain metastases: a clinical observation

    International Nuclear Information System (INIS)

    Objective: T evaluate the efficacy of intracranial arterial infusion chemotherapy in treating advanced lung cancer with brain metastases and to discuss the factors influencing prognosis. Methods: From September 2007 to August 2008, a total of 27 patients of lung cancer with brain metastases received intracranial arterial infusion chemotherapy. This procedure was performed every 4 weeks for three times in succession. Follow-up brain MRI was regularly performed at intervals of eight weeks after the treatment in order to evaluate the therapeutic efficacy, which was conducted until the disease became worse or the patient could tolerate the drug toxicity no longer. Results: All 27 cases were treated 3 times at least, and one case received 7 times. Of the 27 cases, partial response was obtained in 15 (55.6%), stable condition in 8 (29.6%) and deterioration in 4 (14.8%), although no one showed complete alleviation. The effective rate for intracranial lesions was 55.6% (15/27) and the 85.2% of lesions (23/27) were brought under control. Overall median survival time was 7 months. The 6-month survival rate and 1-year survival rate were 81.5% and 14.8%, respectively. Conclusion: Intracranial arterial infusion chemotherapy is one of the most effective methods for the treatment of lung cancer associated with brain metastases. Karnofsky performance status ≥ 60 and absent of extra cranial metastases are good prognostic factors for lung cancer patients with brain metastases. (authors)

  11. Treatment by 131I of differentiated thyroid cancers pulmonary metastases in child. About one case

    International Nuclear Information System (INIS)

    Differentiated thyroid cancers, rare in children, are often at the pulmonary metastases stage. Because of the diffuse character of these metastases, the treatment consists exclusively in iodine 131. We report the case of a girl in whom a papillary carcinoma was diagnosed at the age of five. The post surgery scanning revealed the presence of a pulmonary miliaria. The patient received 7 cures of iodine 131, with a cumulative activity of 650 mCi. These cures allowed to get a remission labeled on the scanning cleaning with iodine 131 as well as the rate of thyroglobulin became undetectable. The follow-up after five years does not detect neither sign of recurrence, nor sign of pulmonary fibrosis, nor second cancer. Ira-therapy stays the preferred treatment for pulmonary metastases of which effectiveness can reach 80%. The risk to develop second cancers is low. Less frequent treatments reduce the risk of pulmonary fibrosis. (N.C.)

    Full Text Available BACKGROUND: Combined intra-operative ablation and resection (CARe is proposed to treat extensive colorectal liver metastases (CLM. This multicenter study was conducted to evaluate overall survival (OS, local recurrence-free survival (LRFS, hepatic recurrence-free survival (HRFS and progression-free survival (PFS, to identify factors associated with survival, and to report complications. MATERIALS AND METHODS: Four centers combined retropectively their clinical experiences regarding CLM treated by CARe. CLM characteristics, pre- and post-operative chemotherapy regimens, surgical procedures, complications and survivals were analyzed. RESULTS: Of the 288 patients who received CARe, 210 (73% had synchronous and 255 (88% had bilateral CLM. Twenty-two patients (8% had extrahepatic disease. Median follow-up was 3.17 years (95%CI 2.83-4.08. Median OS was 3.33 years (95%CI 3.08-4.17 and 5-year OS was 37% (95%CI 29-45. One- and 5-year LRFS from ablated lesions were 87.9% (95%CI 83.3-91.2 and 78.0% (95%CI 71-83, respectively. Median HRFS and PFS were 14 months (95%CI 11-18 and 9 months (95%CI 8-11, respectively. One hundred patients experienced complications: 29 grade I, 68 grade II-III-IV, and three deaths. In the multivariate models adjusted for center, the occurrence of complications was confirmed as a major independent factor associated with 3-year OS (HR 1.80; P = 0.008. Five-year OS was 25.6% (95%CI 14.9-37.6 for patients with complications and 45% (95%CI 33.3-53.4 for patients without. CONCLUSIONS: Recent strategies facing advanced CLM include non-anatomic resections, portal-induced hypertrophy of the future remnant liver and aggressive medical preoperative treatments. CARe has the qualities of an approach that allows effective tumor clearance while maintaining good tolerance for the patient.

  17. Prospective dosimetry of intra-hepatic arterial holmium-166 microsphere therapy of liver metastases

    International Nuclear Information System (INIS)

    Full text: Preliminary results of yttrium 90 microsphere radiation therapy of liver cancer have been promising in patients refractory to all other treatment, but dosimetry of this pure beta emitter cannot be determined accurately. Holmium-166 has a beta emission of comparable energy and range to that of 90Y with the advantage of a gamma photon of 80 keV (6%) that can be imaged. We have calibrated our SPET system for quantitative imaging of a tracer dose of 500 MBq 166Ho-microspheres given via infusaport or directly into the hepatic artery, which lodge in the liver vasculature to preferentially irradiate the tumour. Using CT co-registration to define tumour margins, regions of interest of 5 pixels are positioned over normal liver parenchyma in each SPET slice and the radiation absorbed dose in Gray estimated to determine the additional administered therapy activity of 166Ho that would result in a dose to normal liver dose of 25 Gy. In an ongoing phase I clinical trial, 10 patients have received administered activities up to a maximum of 4.5 GBq.m-2, which gave a predicted radiation absorbed dose to normal liver of 29.3 ± 3.5 Gy using our method of SPET dosimetry. Follow-up SPET imaging at 6 days showed that the actual therapy radiation absorbed dose to normal liver parenchyma was 25.2 ± 4.4 Gy. Tumour radiation absorbed dose in these patients was estimated at 96.6 ± 42.0 Gy

    Full Text Available Medications increasing the survival of patients with metastatic castration-refractory prostate cancer (CRPC are lacking today. In the past 3 years, in the pharmaceutical market there have been a few novel drugs to treat progressive prostate cancer. Abiraterone acetate is an androgen synthesis inhibitor, which is also used to increase the survival of patients with metastatic CRPC that progresses after chemotherapy. The results of treatment for metastatic CRPC depend on a number of factors. Visceral metastases are poor predictors of the course of the disease. The results of abiraterone acetate treatment were analyzed in CRPC patients with visceral metastases.

  2. Heterogeneity of liver cancer and personalized therapy.

    Science.gov (United States)

    Li, Liang; Wang, Hongyang

    2016-09-01

    Liver cancer is an extraordinarily heterogeneous malignant disease among the tumors that have so far been identified. Hepatocellular carcinoma (HCC) arises most frequently in the setting of chronic liver inflammation and fibrosis, and takes a variety of course in individual patients to process to tumor. The risk factors such as HBV and/or HCV infections, aflatoxin infection, abuse alcohol intake, metabolic syndrome, obesity and diabetes are closely related to the environmental and genetic susceptibilities to HCC. The consequent resulting genomic instability, molecular and signal transduction network disorders and microenvironmental discrepancies are characterized by the extraordinary heterogeneity of liver cancer. The histology-based definition of the morphological heterogeneity of liver cancer has been modified and refined to treat patients with targeted therapies, but this still cannot solve all the problems. Lack of consistent outcome for anticancer agents and conventional therapies in liver cancer treatment calls for assessing the benefits of new molecularly targeted drugs and combined therapy, under the heterogeneity condition of tumor. The present review article will provide the complex mechanism and phenotype of liver cancer heterogeneity, and help us to execute precision medicine in a really personalized manner. PMID:26213370

  3. HSV-1 as a novel therapy for breast cancer meningeal metastases.

    Kuruppu, D; Tanabe, K K

    2015-10-01

    Meningeal metastasis is a fatal complication of breast cancer that affects 5-8% of patients. When cancer cells seed in the meninges, their subsequent growth results in severe neurological complications involving the cranial nerves, cerebrum and spinal cord, limiting life expectancy to less than 4 months. The incidences of meningeal metastases increase with prolonged lifespan resulting from treatment advances for primary breast cancer and their metastases. Currently, there is no cure. Aggressive multimodal therapies such as radiation and chemotherapy (intra-cerebrospinal fluid (CSF) and systemic) are ineffective. Therapeutic agents are often quickly cleared from the CSF, while higher doses that can achieve a therapeutic response are highly toxic. The secure guarding of the subarachnoid space by the blood-brain barrier on one side and the blood-CSF barrier on the other prevents chemotherapy from reaching cancer cells in the meninges. These challenges with treating meningeal metastases highlight the urgent need for a new therapeutic modality. An ideal treatment would be an agent that avoids rapid clearance, remains within the CSF, reaches the meninges and selectively destroys tumor cells. Replication conditional oncolytic herpes simplex virus type 1 (HSV-1) may be effective in this regard. Viral oncolysis, the destruction of cancer cells by replicating virus, is under clinical investigation for cancers that are unresponsive to current therapies. It is based on the model of multiple cycles of lytic virus replication in cancer cells that amplify the injected dose. The therapeutic potential of oncolytic HSV-1 for breast cancer meningeal metastases is discussed here. HSV-1 could be a potential novel treatment for meningeal metastases that can be translated to the clinic. PMID:26384139

    MR contrast agents increase hepatic tumor conspicuity, as measured in terms of contrast-to-noise (C/N) ratios. With an animal model of hepatic metastases from breast cancer, IV administration of Gd-DTPA (0.2 mmol/kg) shows a biphasic time response, transiently increasing the signal intensity of liver relative to tumor, with C/N ratio magnitudes increasing from -5.7 to -16.3 (SE 250/20); after a delay, the signal intensity of tumor increases relative to liver with a reversal of the C/N sign from negative to positive and an increase in the C/N magnitude to +25.0. IV administration of ferrite particles (0.05 mmol Fe/kg) shows a monophasic time response, increasing signal intensity of tumor relative to liver from +1.5 to +49.5 (SE 500/30). When both contrast agents were administered together (dual-contrast technique), the tumor-liver C/N magnitude reached a maximum of +67.8 (SE 500/30) 12 min after drug infusion. Analysis of individual contrast and noise factors contributing to this technique revealed a strong correlation between the signal intensity of liver and the signal intensity of ghost artifacts, which increase after administration of Gd-DTPA (r = .89) and decrease after administration of ferrite (r = 1.0). Dual-contrast imaging shows a synergistic addition of contrast and suppression of noise from ghost artifacts, maximizing the C/N and increasing the conspicuity of focal liver lesions. PMID:3257610

  5. Treatment outcomes using CyberKnife for brain metastases from lung cancer

    International Nuclear Information System (INIS)

    We investigated the clinical outcomes following treatment using stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (SRT) for brain metastases from lung cancer. A total of 67 patients with 109 brain metastases from lung cancer treated using CyberKnife between 1998 and 2011 were retrospectively analyzed. SRS (median dose, 24 Gy) was used to treat 79 lesions, and 3-fraction SRT (median dose, 30 Gy) was used to treat 30 lesions. The median follow-up time was 9.4 months (range, 0.4 - 125 months). The 1-year local control rate was 83.3%, and the 1-year distant brain failure rate was 30.1%. The median survival time was 13.1 months, and the 1- and 3-year overall survival (OS) rates were 54.8% and 25.9%, respectively. On multivariate analysis, three factors were found to be statistically significant predictors of OS: (1) presence of uncontrolled primary disease [hazard ratio (HR) = 3.04; P = 0.002]; (2) Brinkman index (BI) ≥ 1000 (HR = 2.75; P = 0.007); and (3) pulmonary metastases (HR = 3.54; P = 0.009). Radionecrosis and worsening of neurocognitive function after radiosurgery were observed in 5 (7%) and 3 (4%) patients, respectively. Our results indicated that SRS/SRT for brain metastases from lung cancer was effective. Uncontrolled primary disease, high BI, and pulmonary metastases at treatment were significant risk factors for OS. (author)

  6. Pulmonary metastases of the thyroid differentiated cancer: role of iodine 131 in early detecting and treatment

    International Nuclear Information System (INIS)

    The detection of functional pulmonary metastases of differentiated cancer in thyroid is often done in the radiological stage and a 10 year survival is of the order of 50%. We have evaluated the results of a protocol based on to principles: 1. systematic administration of 3.7 GBq of iodine 131 after any total thyroidectomy; 2. repeated treatment by iodine 131 of functional metastases without fixed limit of cumulated activity. Five hundreds and nine differentiated cancers of thyroid were operated between 1970 and 1996. A total thyroidectomy was decided in 76% of cases followed by a iodine 131 therapy. Thirty two patients presented pulmonary metastases. This work refers to 20 patients in which the metastases were functional (fixating). These metastases were not visible on the thorax radiography in 11 patients (group 1) but visible in 9 patients (group 2). In group 1, the metastases were detected at initial treatment by iodine 131 in 11 patients (100%). Three patients had also an osseous metastasis. The average span of surveillance for this group is 9 years. The pulmonary fixation disappeared in 9 patients. A single decease has been recorded, due to a cervical recurrence. In group 2 the metastases were present at initial accounting examination in 8/9 patients. Four of them presented also osseous metastases. The treatment with iodine 131 was associated to a pulmonary metastasis-ectomy in 3 cases and to a surgery and/or osseous radiotherapy in 3 cases. A remission of the metastases was noted in all the patients as well as 2 healings. The average span survival was 8 years. A patient deceased 2 years after interrupting the treatment. The 10 year survival for the ensemble of this series, calculated by the Kaplan-Meier method, was 87%. In conclusion: 1. the therapy by iodine 131 after thyroidectomy allows the early diagnosis of functional metastases prior to the rise of thyroglobulin rate or appearance of radiological signs; 2. the repeated treatment by iodine 131 associated

    Full Text Available Metastatic lesions in the liver derived from colorectal cancer rarely invade the portal vein macroscopically. Portal vein tumor thrombus is commonly associated with hepatocellular carcinoma. Colorectal liver metastases are usually accompanied by microscopic tumor invasion into the intrahepatic portal vein, and the incidence of macroscopic tumor thrombus in the trunk of the portal vein is rare. Here, we provide unique appearance of metastatic colorectal cancer. To the best of our knowledge, macroscopically, the right portal vein filled with the tumor thrombus without any tumor in liver parenchyma has been quite rare.

    Full Text Available Introduction. The role of hepatic resection in patients with liver metastases from gastroenteropancreatic neuroendocrine tumors (GEP-NETs is still poorly defined. Therefore, we examined the results obtained with surgical resection and other locoregional or systemic therapies by reviewing the recent literature on this topic. We performed the meta-analysis for comparing surgical resection of hepatic metastases with other treatments. Materials and Methods. In this systematic review and meta-analysis of observational studies, the literature search was undertaken between 1990 and 2012 looking for studies evaluating the different survivals between patients treated with surgical resection of hepatic metastases and with other surgical or nonsurgical therapies. The studies were evaluated for quality, publication bias, and heterogeneity. Pooled hazard ratio (HR estimates and 95% confidence intervals (CI.95 were calculated using fixed-effects model. Results. We selected six studies in the review, five of which were suitable for meta-analysis. We found a significant longer survival in patients treated with hepatic resection than embolisation HR 0.34 (CI.95 0.21–0.55 or all other nonsurgical treatments HR 0.45 (CI.95 0.34–0.60. Only one study compared surgical resection with liver transplantation and meta-analysis was not feasible. Conclusions. Our meta-analysis provides evidence supporting the hypothesis that hepatic resection increases overall survival in patients with liver metastases from GEP-NETs. Further randomized clinical trials are needed to confirm these findings and it would be desirable to identify new markers to properly select patients for surgical treatment.

  9. Metastases and Colon Cancer Tumor Growth Display Divergent Responses to Modulation of Canonical WNT Signaling.

    Directory of Open Access Journals (Sweden)

    Chandan Seth

    Full Text Available Human colon cancers commonly harbor loss of function mutations in APC, a repressor of the canonical WNT pathway, thus leading to hyperactive WNT-TCF signaling. Re-establishment of Apc function in mice, engineered to conditionally repress Apc through RNAi, resolve the intestinal tumors formed due to hyperactivated Wnt-Tcf signaling. These and other results have prompted the search for specific WNT pathway antagonists as therapeutics for clinically problematic human colon cancers and associated metastases, which remain largely incurable. This widely accepted view seems at odds with a number of findings using patient-derived material: Canonical TCF targets are repressed, instead of being hyperactivated, in advanced colon cancers, and repression of TCF function does not generally result in tumor regression in xenografts. The results of a number of genetic mouse studies have also suggested that canonical WNT-TCF signaling drives metastases, but direct in vivo tests are lacking, and, surprisingly, TCF repression can enhance directly seeded metastatic growth. Here we have addressed the abilities of enhanced and blocked WNT-TCF signaling to alter tumor growth and distant metastases using xenografts of advanced human colon cancers in mice. We find that endogenous WNT-TCF signaling is mostly anti-metastatic since downregulation of TCF function with dnTCF generally enhances metastatic spread. Consistently, elevating the level of WNT signaling, by increasing the levels of WNT ligands, is not generally pro-metastatic. Our present and previous data reveal a heterogeneous response to modulating WNT-TCF signaling in human cancer cells. Nevertheless, the findings that a fraction of colon cancers tested require WNT-TCF signaling for tumor growth but all respond to repressed signaling by increasing metastases beg for a reevaluation of the goal of blocking WNT-TCF signaling to universally treat colon cancers. Our data suggest that WNT-TCF blockade may be effective

  10. Outcome of small cell lung cancer (SCLC) patients with brain metastases in a routine clinical setting

    International Nuclear Information System (INIS)

    Small cell lung cancer (SCLC) represents approximately 13 to 18% of all lung cancers. It is the most aggressive among lung cancers, mostly presented at an advanced stage, with median survival rates of 10 to12 months in patients treated with standard chemotherapy and radiotherapy. In approximately 15-20% of patients brain metastases are present already at the time of primary diagnosis; however, it is unclear how much it influences the outcome of disease according the other metastatic localisation. The objective of this analysis was to evaluate the median survival of SCLC patients treated by specific therapy (chemotherapy and/or radiotherapy) with regard to the presence or absence of brain metastases at the time of diagnosis. All SCLC patients have been treated in a routine clinical practice and followed up at the University Clinic Golnik in Slovenia. In the retrospective study the medical files from 2002 to 2007 were review. All patients with cytological or histological confirmed disease and eligible for specific oncological treatment were included in the study. They have been treated according to the guidelines valid at the time. Chemotherapy and regular followed-up were carried out at the University Clinic Golnik and radiotherapy at the Institute of Oncology Ljubljana. We found 251 patients eligible for the study. The median age of them was 65 years, majority were male (67%), smokers or ex-smokers (98%), with performance status 0 to 1 (83%). At the time of diagnosis no metastases were found in 64 patients (25.5%) and metastases outside the brain were presented in 153 (61.0%). Brain metastases, confirmed by a CT scan, were present in 34 patients (13.5%), most of them had also metastases at other localisations. All patients received chemotherapy and all patients with confirmed brain metastases received whole brain irradiation (WBRT). The radiotherapy with radical dose at primary tumour was delivered to 27 patients with limited disease and they got 4–6 cycles of

    To identify the clinical features and independent predictors of survival in patients with bone metastases from prostate cancer (PCa).We retrospectively analysed 115 PCa patients with bone metastases between 1997 and 2009.The overall survival rate after bone metastases was calculated using the Kaplan-Meier method.The prognostic factors were identified by univariate analysis using a log-rank test and by multivariate analysis using Cox proportional hazards regression models.The follow-up rate was 100%,the follow-up cases during 1,3 and 5 years were 103,79 and 55,respectively.The 1-,3- and 5-year survival rates were 89.1%,60.9% and 49.8%,respectively,with a median survival time of 48.5 months for patients with bone metastases from PCa.In univariate analysis,age,Gleason score,clinical stage,the number of bone lesions,alkaline phosphatase (ALP) level,invasion of neighbouring organs and non-regional lymph node metastases were correlated with prognosis.By multivariate analysis using Cox regression,ALP level,Gleason score and non-regional lymph node metastases were independent prognostic factors.These prognostic factors will help us to determine the appropriate dose and fraction of radiotherapy for these patients.

  13. Metastatic susceptibility locus, an 8p hot-spot for tumour progression disrupted in colorectal liver metastases: 13 candidate genes examined at the DNA, mRNA and protein level

    International Nuclear Information System (INIS)

    Mortality from colorectal cancer is mainly due to metastatic liver disease. Improved understanding of the molecular events underlying metastasis is crucial for the development of new methods for early detection and treatment of colorectal cancer. Loss of chromosome 8p is frequently seen in colorectal cancer and implicated in later stage disease and metastasis, although a single metastasis suppressor gene has yet to be identified. We therefore examined 8p for genes involved in colorectal cancer progression. Loss of heterozygosity analyses were used to map genetic loss in colorectal liver metastases. Candidate genes in the region of loss were investigated in clinical samples from 44 patients, including 6 with matched colon normal, colon tumour and liver metastasis. We investigated gene disruption at the level of DNA, mRNA and protein using a combination of mutation, semi-quantitative real-time PCR, western blotting and immunohistochemical analyses. We mapped a 2 Mb region of 8p21-22 with loss of heterozygosity in 73% of samples; 8/11 liver metastasis samples had loss which was not present in the corresponding matched primary colon tumour. 13 candidate genes were identified for further analysis. Both up and down-regulation of 8p21-22 gene expression was associated with metastasis. ADAMDEC1 mRNA and protein expression decreased during both tumourigenesis and tumour progression. Increased STC1 and LOXL2 mRNA expression occurred during tumourigenesis. Liver metastases with low DcR1/TNFRSF10C mRNA expression were more likely to present with extrahepatic metastases (p = 0.005). A novel germline truncating mutation of DR5/TNFRSF10B was identified, and DR4/TNFRSF10A SNP rs4872077 was associated with the development of liver metastases (p = 0.02). Our data confirm that genes on 8p21-22 are dysregulated during colorectal cancer progression. Interestingly, however, instead of harbouring a single candidate colorectal metastasis suppressor 8p21-22 appears to be a hot-spot for

    Full Text Available Surgery is the only curative treatment in patients with colorectal liver metastases (CLM, but only 10-20% of patients are eligible. High Intensity Focused Ultrasound (HIFU technology is of proven value in several indications, notably prostate cancer. Its intra-operative use in patients with CLM has not previously been studied. Preclinical work suggested the safety and feasibility of a new HIFU device capable of ablating volumes of up to 2cm x 2cm in a few seconds.We conducted a prospective, single-centre phase I-IIa trial. HIFU was delivered immediately before scheduled hepatectomy. To demonstrate the safety and efficacy of rapidly ablating liver parenchyma, ablations were performed on healthy tissue within the areas scheduled for resection.In total, 30 ablations were carried out in 15 patients. These ablations were all generated within 40 seconds and on average measured 27.5mm x 21.0mm. The phase I study (n = 6 showed that use of the HIFU device was feasible and safe and did not damage neighbouring tissue. The phase IIa study (n = 9 showed both that the area of ablation could be precisely targeted on a previously implanted metallic mark (used to represent a major anatomical structure and that ablations could be undertaken deliberately to avoid such a mark. Ablations were achieved with a precision of 1-2 mm.HIFU was feasible, safe and effective in ablating areas of liver scheduled for resection. The next stage is a phase IIb study which will attempt ablation of small metastases with a 5 mm margin, again prior to planned resection.ClinicalTrials.govNCT01489787.

    Full Text Available A case of squamous cell carcinoma of the tongue with advanced N3 cervical lymph node metastases in an 80-year-old female is reported. The patient was treated with a combination of radiotherapy (2 Gy/day, total 60 Gy, superselective intra-arterial chemotherapy via a superficial temporal artery and a femoral artery (docetaxel, total 124 mg; cisplatin, total 135 mg, and four sessions of hyperthermia for cervical lymph node metastases. The tumor responded well to therapy, and 18-fluorodeoxyglucose uptake in both primary and neck lesions disappeared on positron emission tomography-computed tomography. The patient has shown no clinical or radiological evidence of local recurrence or distant metastases 6 years after the end of treatment. Advanced oral cancer patients with N3 cervical lymph node metastases are particularly difficult to treat and have a poor prognosis. This method of thermochemoradiotherapy seems a promising modality for patients with N3 cervical lymph node metastases of oral cancer.

  17. Radioimmune imaging of bone marrow in patients with suspected bone metastases from primary breast cancer

    International Nuclear Information System (INIS)

    Radioimmune imaging of bone marrow was performed by technetium-99m- (99mTc) labeled antigranulocyte monoclonal antibody BW 250/183 (AGMoAb) scans in 32 patients with suspected bone metastases from primary breast cancer. AGMoAb scans showed bone marrow defects in 25/32 (78%) patients; bone invasion was subsequently confirmed in 23 (72%) patients. Conventional bone scans performed within the same week detected bone metastases in 17/32 (53%) patients (p less than 0.001). AGMoAb scans detected more sites indicating metastatic disease than bone scans in 12 of these 17 patients (71%). All patients with bone metastases in the axial skeleton had bone marrow defects at least at the sites of bone metastases. Of 15 patients with normal, or indicative of, benign disease bone scans, 8 patients (53%) presented with bone marrow defects in the AGMoAb scans. Bone invasion was confirmed in six of them. AGMoAb bone marrow scans provide a method for the early detection of bone metastatic invasion in patients with breast cancer and suspected bone metastases

  18. New Breast Cancer Recursive Partitioning Analysis Prognostic Index in Patients With Newly Diagnosed Brain Metastases

    International Nuclear Information System (INIS)

    Purpose: The aim of the study was to present a new breast cancer recursive partitioning analysis (RPA) prognostic index for patients with newly diagnosed brain metastases as a guide in clinical decision making. Methods and Materials: A prospectively collected group of 441 consecutive patients with breast cancer and brain metastases treated between the years 2003 and 2009 was assessed. Prognostic factors significant for univariate analysis were included into RPA. Results: Three prognostic classes of a new breast cancer RPA prognostic index were selected. The median survival of patients within prognostic Classes I, II, and III was 29, 9, and 2.4 months, respectively (p < 0.0001). Class I included patients with one or two brain metastases, without extracranial disease or with controlled extracranial disease, and with Karnofsky performance status (KPS) of 100. Class III included patients with multiple brain metastases with KPS of ≤60. Class II included all other cases. Conclusions: The breast cancer RPA prognostic index is an easy and valuable tool for use in clinical practice. It can select patients who require aggressive treatment and those in whom whole-brain radiotherapy or symptomatic therapy is the most reasonable option. An individual approach is required for patients from prognostic Class II.

    Brain metastases occur in about 10% to 30% of breast cancer patients, which culminates in a poor prognosis. It is, therefore, critical to understand the molecular mechanisms underlying brain metastatic processes to identify relevant targets. We hypothesized that breast cancer cells must express brain-associated markers that would enable their invasion and survival in the brain microenvironment. We assessed a panel of brain-predominant markers and found an elevation of several neuronal markers (βIII-tubulin, Nestin, and AchE) in brain metastatic breast cancer cells. Among these neuronal predominant markers, in silico analysis revealed overexpression of βIII-tubulin (TUBB3) in breast cancer brain metastases (BCBM) and its expression was significantly associated with distant metastases. TUBB3 knockdown studies were conducted in breast cancer models (MDA-Br, GLIM2, and MDA-MB-468), which revealed significant reduction in their invasive capabilities. MDA-Br cells with suppressed TUBB3 also demonstrated loss of key signaling molecules such as β3 integrin, pFAK, and pSrc in vitro. Furthermore, TUBB3 knockdown in a brain metastatic breast cancer cell line compromised its metastatic ability in vivo, and significantly improved survival in a brain metastasis model. These results implicate a critical role of TUBB3 in conferring brain metastatic potential to breast cancer cells. PMID:25724666

  4. Mathematical modeling of liver metastases tumour growth and control with radiotherapy

    International Nuclear Information System (INIS)

    Generating an optimized radiation treatment plan requires understanding the factors affecting tumour control. Mathematical models of tumour dynamics may help in future studies of factors predicting tumour sensitivity to radiotherapy. In this study, a time-dependent differential model, incorporating biological cancer markers, is presented to describe pre-treatment tumour growth, response to radiation, and recurrence. The model uses Gompertzian-Exponential growth to model pre-treatment tumour growth. The effect of radiotherapy is handled by a realistic cell-kill term that includes a volume-dependent change in tumour sensitivity. Post-treatment, a Gompertzian, accelerated, delayed repopulation is employed. As proof of concept, we examined the fit of the model's prediction using various liver enzyme levels as markers of metastatic liver tumour growth in a liver cancer patient. A tumour clonogen population model was formulated. Each enzyme was coupled to the same tumour population, and served as surrogates of the tumour. This dynamical model was solved numerically and compared to the measured enzyme levels. By minimizing the mean-squared error of the model enzyme predictions, we determined the following tumour model parameters: growth rate prior to treatment was 0.52% per day; the fractional radiation cell kill for the prescribed dose (60 Gy in 15 fractions) was 42% per day, and the tumour repopulation rate was 2.9% per day. These preliminary results provided the basis to test the model in a larger series of patients, to apply biological markers for improving the efficacy of radiotherapy by determining the underlying tumour dynamics.

  5. A case of jawbone necrosis resulting from radiation treatment of multiple bone metastases from breast cancer

    International Nuclear Information System (INIS)

    Radiotherapy for malignant tumors is sometimes associated with side effects that can appear early in the course of treatment. Radiation necrosis of the jawbone sometimes occurs after exposure to a radiation dose of 60 Gy or more for treatment of malignant tumors of the head and neck, and this can have a marked influence on subsequent dental care. The effect is often more marked in the lower than in the upper jaw, and becomes typically evident at the time of tooth extraction. As well as cancers of the head and neck, patients with breast cancer can also be affected by radiation necrosis of the jawbone. It is well known that the rate of bone metastases from breast cancer is much high especially appearing the mandibular in the head and neck lesions. Here we report an overview of jawbone necrosis in the light of our experience of one such case following radiation treatment of multiple bone metastases from breast cancer. (author)

  7. Prospective comparison of computed tomography and magnetic resonance imaging for liver cancer delineation using deformable image registration

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to compare magnetic resonance imaging (MRI) with computed tomography (CT) for liver cancer tumor definition for high-precision radiotherapy planning. Methods and Materials: Diagnostic quality MRI scans and triphasic CT scans, with the liver immobilized in exhale, were obtained at the time of radiation planning for 26 patients with unresectable liver metastases (n = 8), hepatocellular carcinoma (n = 10), and cholangiocarcinoma (n = 8). On the CT and MRI series best demonstrating the tumor, the liver and gross tumor volumes (GTVs) were contoured, and intrahepatic anatomic reference points were identified. Deformable registration was used to register the liver from the CT with that from the MRI. Results: A difference in the number of tumor foci was seen on CT vs. MRI in 5 patients with hepatocellular carcinoma: MRI showed more foci in 3 patients, CT in 2. After deformable registration of the livers, the population median of the average distance between the CT tumor surface and MRI tumor surface was 3.7 mm (2.2-21.3 mm). The median percentage of tumor surface area that differed by ≥5 mm was 26% (1-86%). Median percentage concordance volumes were 81% (77-86%) in metastases, 77% (60-88%) in hepatocellular carcinoma and 64% (25-85%) in cholangiocarcinoma. Conclusion: Differences between MRI-defined liver cancer GTVs and CT-defined GTVs can be substantial and are more common in primary liver cancer

  8. Is there a genetic signature for liver metastasis in colorectal cancer?

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Even though liver metastasis accounts for the vast majority of cancer deaths in patients with colorectal cancer (CRC), fundamental questions about the molecular and cellular mechanisms of liver metastasis still remain unanswered. Determination of gene expression profiles by microarray technology has improved our knowledge of CRC molecular pathways. However, defined gene signatures are highly variable among studies. Expression profiles and molecular markers have been specifically linked to liver metastases mechanistic paths in CRC. However, to date, none of the identified signatures or molecular markers has been successfully validated as a diagnostic or prognostic tool applicable to routine clinical practice. To obtain a genetic signature for liver metastasis in CRC, measures to improve reproducibility, to increase consistency, and to validate results need to be implemented. Alternatives to expression profiling with microarray technology are continuing to be used. In the recent past, many genes codifying for proteins that are directly or indirectly involved in adhesion, invasion, angiogenesis, survival and cell growth have been linked to mechanisms of liver metastases in CRC.

  17. Radiofrequency Ablation of Liver Metastases-Software-Assisted Evaluation of the Ablation Zone in MDCT: Tumor-Free Follow-Up Versus Local Recurrent Disease

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate differences in change of size and CT value between local recurrences and tumor-free areas after CT-guided radiofrequency ablation (RFA) of hepatic metastases during follow-up by means of dedicated software for automatic evaluation of hepatic lesions. Thirty-two patients with 54 liver metastases from breast or colorectal cancer underwent triphasic contrast-enhanced multidetector-row computed tomography (MDCT) to evaluate hepatic metastatic spread and localization before CT-guided RFA and for follow-up after intervention. Sixteen of these patients (65.1 ± 10.3 years) with 30 metastases stayed tumor-free (group 1), while the other group (n = 16 with 24 metastases; 62.0 ± 13.8 years) suffered from local recurrent disease (group 2). Applying an automated software tool (SyngoCT Oncology; Siemens Healthcare, Forchheim, Germany), size parameters (volume, RECIST, WHO) and attenuation were measured within the lesions before, 1 day after, and 28 days after RFA treatment. The natural logarithm (ln) of the quotient of the volume 1 day versus 28 days after RFA treament was computed: lnQ1//28/0volume. Analogously, ln ratios of RECIST, WHO, and attenuation were computed and statistically evaluated by repeated-measures ANOVA. One lesion in group 2 was excluded from further evaluation due to automated missegmentation. Statistically significant differences between the two groups were observed with respect to initial volume, RECIST, and WHO (p attenuation (p = 0.0527), showing higher values for group 1 (-0.4 ± 0.3) compared to group 2 (-0.2 ± 0.2). In conclusion, hepatic metastases and their zone of coagulation necrosis after RFA differed significantly between tumor-free and local-recurrent ablation zones with respect to the corresponding size parameters. A new parameter (lnQ1//28/0volume/RECIST/WHO/attenuation) was introduced, which appears to be of prognostic value at early follow-up CT.

    Liver cancer is an aggressive malignant disease with a poor prognosis. Patients with liver cancer are usually diagnosed at an advanced stage and thus miss the opportunity for surgical resection. Chemotherapy and radiofrequency ablation, which target tumor bulk, have exhibited limited therapeutic efficacy to date. Liver cancer stem cells (CSCs) are a small subset of undifferentiated cells existed in liver cancer, which are considered to be responsible for liver cancer initiation, metastasis, relapse and chemoresistance. Elucidating liver CSC characteristics and disclosing their regulatory mechanism might not only deepen our understanding of the pathogenesis of liver cancer but also facilitate the development of diagnostic, prognostic and therapeutic approaches to improve the clinical management of liver cancer. In this review, we will summarize the recent advances in liver CSC research in terms of the origin, identification, regulation and clinical correlation. PMID:26272183

    Brain metastases remain a significant challenge in the treatment of breast cancer patients due to the unique environment posed by the central nervous system. A better understanding of the biology of breast cancer cells that have metastasized to the brain is required to develop improved therapies. A recent Proceedings of the National Academy of Sciences article demonstrates that breast cancer cells in the brain microenvironment express γ-aminobutyric acid (GABA)-related genes, enabling them to...

  20. Detection of metastases in breast cancer patients. Comparison of FDG PET with chest X-ray, bone scintigraphy and ultrasound of the abdomen

    International Nuclear Information System (INIS)

    Distant metastases at primary diagnosis are a prognostic key factor in breast cancer patients and play a central role in therapeutic decisions. To detect them, chest X-ray, abdominal ultrasound, and bone scintigraphy are performed as standard of care in Germany and many centers worldwide. Although FDG PET detects metastatic disease with high accuracy, its diagnostic value in breast cancer still needs to be defined. The aim of this study was to compare the diagnostic performance of FDG PET with conventional imaging. Patients, methods: a retrospective analysis of 119 breast cancer patients who presented for staging was performed. Whole-body FDG-PET (n = 119) was compared with chest X-ray (n = 106) and bone scintigraphy (n = 95). Each imaging modality was independently assessed and classified for metastasis (negative, equivocal and positive). The results of abdominal ultrasound (n = 100) were classified as negative and positive according to written reports. Imaging results were compared with clinical follow-up including follow-up imaging procedures and histopathology. Results: FDG-PET detected distant metastases with a sensitivity of 87.3% and a specificity of 83.3%. In
