Restaging Patients With Hepatocellular Carcinoma Before Additional Treatment Decisions: A Multicenter Cohort Study.

Prognostic assessment of patients with hepatocellular carcinoma (HCC) at the time of diagnosis remains controversial and becomes even more complex at the time of restaging when new variables need to be considered. The aim of the current study was to evaluate the prognostic utility of restaging patients before proceeding with additional therapies for HCC. Two independent Italian prospective databases were used to identify 1,196 (training cohort) and 648 (validation cohort) consecutive patients with HCC treated over the same study period (2008-2015) who had complete restaging before decisions about additional therapies. The performance of the Italian Liver Cancer (ITA.LI.CA) prognostic score at restaging was compared with that of the Barcelona Clinic Liver Cancer, Hong Kong Liver Cancer, and Cancer of the Liver Italian Program systems. A multivariable Cox survival analysis was performed to identify baseline, restaging, or dynamic variables that were able to improve the predictive performance of the prognostic systems. At restaging, 35.3% of patients maintained stable disease; most patients were either down-staged by treatment (27.2%) or had disease progression (37.5%). The ITA.LI.CA scoring system at restaging demonstrated the best prognostic performance in both the training and validation cohorts (c-index 0.707 and 0.722, respectively) among all systems examined. On multivariable analysis, several variables improved the prognostic ability of the ITA.LI.CA score at restaging, including progressive disease after the first treatment, Model for End-Stage Liver Disease at restaging, and choice of nonsurgical treatment as additional therapy. A new ITA.LI.CA restaging model was created that demonstrated high discriminative power in both the training and validation cohorts (c-index 0.753 and 0.745, respectively). CONCLUSION: Although the ITA.LI.CA score demonstrated the best prognostic performance at restaging, other variables should be considered to improve the prognostic assessment of patients at the time of deciding additional therapies for HCC.

Videolaparoscopic microwave ablation in patients with HCC at a European high-volume center: Results of 815 procedures.

BACKGROUND: Videolaparoscopic (VL) microwave ablation (MWA) is not included in most of the international guidelines as a therapeutic option for hepatocellular carcinoma (HCC). Aim of this study was to assess the safety of VL MWA in patients with HCC for whom resection or percutaneous ablation is unsuitable. METHODS: A retrospective analysis was performed on a prospective database of patients with HCC treated with VL MWA at our institution from 2009 to 2016. Patient demographics, operational characteristics, and complications were recorded. Statistical analysis was performed to identify safety profile, overall survival and recurrence rate. RESULTS: A total of 815 VL MWA were performed in 674 patients with a mean age of 64 years. Patients had a mean Model for End-stage Liver Disease score of 10 (±3); 32.8% were Child B, 44.1% Barcelona Clinic Liver Cancer B-C. Perioperative mortality was 0.4%. Overall morbidity was 30.8%, with Dindo-Clavien complications ≥3 in 2%. The median length of stay was 2 days. In 43.1% VL MWA was the first-line therapy. Overall 1-, 3-, and 5-year survival rates were 81.9%, 54.9%, and 35.9%. CONCLUSIONS: The present is the largest series of VL ablation and the bigger number of patients with HCC treated with MW reported nowadays. It confirms the safety of a minimally invasive procedure for patients with HCC when resection or percutaneous ablation is not feasible.

A review discussing the use of polyethylene glycol microspheres in the treatment of hepatocellular carcinoma.

Transarterial chemoembolization (TACE) is indicated in unresectable hepatocellular carcinoma and allows the delivery of embolics inside tumor vascularization to reduce blood supply and release gradually the drug. This lowers the systemic exposure to chemotherapeutics, while increasing their local concentration and tissue necrosis that is higher than conventional TACE. The technology of TACE has seen the introduction of several types of embolics that are made of different materials. Available embolics for TACE include: drug-eluting beads (DC beads), acrylic copolymer, tris-acrylic microspheres and polyethylene glycol (PEG) microspheres. Few studies are available on PEG embolics and their use for TACE. This review focuses on the efficacy and safety of TACE performed with PEG microspheres for the treatment of hepatocellular carcinoma and discusses future therapeutic advantages.

Immune characterization of breast cancer metastases: prognostic implications.

BACKGROUND: Tumor-infiltrating lymphocytes (TILs) evaluated in primary breast cancer (BC) convey prognostic information. Limited data in the metastatic setting are available. METHODS: Secondary lesions from 94 BC patients, 43 triple-negative (TN) and 51 HER2-positive, were evaluated for TILs and expression of CD8, FOXP3, and PD-L1 by immunohistochemistry. RESULTS: TILs levels on metastasis were generally low (median 5%) and did not differ between TN and HER2+ tumors. Younger patients showed significantly lower TILs (p = 0.002). In HER2+ patients, TILs were higher in lung metastases as compared to other sites (p = 0.038). TILs composition was different across metastatic sites: skin metastases presented higher FOXP3 (p = 0.002) and lower CD8/FOXP3 ratio (p = 0.032). Patients treated for metastatic BC prior to biopsy had lower CD8 (overall: p = 0.005, HER2+: p = 0.011, TN: p = 0.075). In TN patients, median overall survival (OS) was 11.8 and 62.9 months for patients with low and high TILs, respectively (HR 0.29, 95%CI 0.11-0.76, log-rank p = 0.008). CD8/FOXP3 ratio was also prognostic in TN patients (median OS 8.0, 13.2, and 54.0 months in 1st, 2nd and 3th tertile, log-rank p = 0.019). Both TILs and CD8/FOXP3 ratio were independent factors at multivariate analysis. Counterintuitively, in HER2+ BC, low TILs tumors showed better prognosis (median OS 53.7 vs 39.9 months in TILs low and TILs high, not statistically significant). CONCLUSIONS: Our findings indicate the relevance of TILs as prognostic biomarker for TNBC even in the advanced setting and provide novel hypothesis-generating data on potential sources of immune heterogeneity of metastatic BC.

Chemoembolization in Conjunction with Bevacizumab: Preliminary Results.

Transarterial chemoembolization is an effective, minimally invasive therapy that is widely used for treatment of unresectable colorectal cancer liver metastases (CRC-LM). However, chemoembolization induces a hypoxic microenvironment, which increases neoangiogenesis and may promote early progression. For this reason, transarterial chemoembolization efficacy may be improved by combining it with an angiogenesis inhibitor, such as bevacizumab. This report shows that transarterial chemoembolization with irinotecan-loaded polyethylene glycol embolics and bevacizumab therapy was effective and well tolerated by 6 patients with CRC-LM, resulting in a disease control rate of 83% and an overall improvement in quality of life.

Angiogenesis inhibitors and symptomatic anal ulcers in metastatic colorectal cancer patients *.

BACKGROUND: Angiogenesis inhibitors are a standard first-line treatment for metastatic colorectal cancer. Anal canal pain is a common adverse event, but its cause has never been described. The aim of the study was to evaluate the association between the use of angiogenesis inhibitors and symptomatic anal ulcer development. METHODS: This retrospective cohort study included all 601 consecutive metastatic colorectal cancer patients undergoing first line treatment from January 2010 to June 2016 at the Veneto Institute of Oncology. Details about patient characteristics, treatment and proctology reports were retrieved and compared. Vascularization of the anal canal was evaluated with contrast MRI. RESULTS: Fifty out of 601 patients reported perianal complaints during treatment and underwent proctologic evaluation. Among those, 16 were found to have an anal ulcer. Symptomatic anal ulcers occurred only in patients receiving bevacizumab (4.2% vs. 0% with other regimens, p = .009). The peak incidence was 4-8 weeks after treatment start. Vascularization of anal canal was significantly lower in patients treated with bevacizumab (p = .03). Hypertension and hemorrhoids were associated with a lower risk of anal ulcer occurrence (p = .009 and p = .036). Pain intensity was severe. All attempts at symptomatic treatment only led to transient benefit. The absence of symptomatic ulcers was protective against earlier permanent discontinuation of treatment (HR = .22, 95%CI: 0.04-0.62). CONCLUSIONS: The development of symptomatic anal ulcers in patients receiving angiogenesis inhibitor is a common adverse event which can compromise the continuation of cancer therapy. We recommend an early proctologic evaluation in case of anal symptoms with the aim to prevent and timely manage such complication.

Transarterial Chemoembolization with Small Drug-Eluting Beads in Patients with Hepatocellular Carcinoma: Experience from a Cohort of 421 Patients at an Italian Center.

PURPOSE: To assess the safety, tolerability, and efficacy of small drug-eluting embolic (DEE) agents (70-150 µm) for chemoembolization of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: This single-center, single-arm, retrospective study involved 421 patients (mean age, 66.1 y ± 9.8 [standard deviation]) with Barcelona Clinic Liver Cancer (BCLC) stage A (n = 88), B (n = 140), or C (n = 193) HCC and Child-Pugh class A (n = 233) or B (n = 188) cirrhosis. Patients had a mean of 7.2 lesions ± 4.8 (range, 1-21; mean diameter of target lesion, 21.4 cm ± 8.1; unilobar, n = 132; bilobar, n = 289; portal vein involvement, n = 193). One (n = 320) or 2 (n = 101) vials of small DEEs loaded with doxorubicin 50 mg per vial were delivered selectively (ie, segmentally) or superselectively (ie, directly into the tumor-feeding vessel) until complete delivery or stasis/near-stasis. Treatment was repeated in patients with partial response or stable disease at 1- or 3-month follow-up (mean, 2.0 cycles ± 0.9). Adverse events within 30 days of chemoembolization, response per modified Response Evaluation Criteria In Solid Tumors (mRECIST), and survival were assessed. RESULTS: Within 30 days after treatment, no deaths or bleeding events occurred, but all patients had at least 1 episode of postembolization syndrome (pain, fever, and/or nausea/vomiting; 27.1% grade 3/4 per National Cancer Institute Common Terminology Criteria for Adverse Events, version 3.0) and increased bilirubin and liver aminotransferase levels (0.2% and 5.9% grade 3/4, respectively). Overall response rates were 94.5% at 3 months and 99.5% at 6 months. Median overall survival was 42.0 months (95% confidence interval, 38.0-43.0 mo). CONCLUSIONS: Chemoembolization with small DEE agents is well tolerated and an effective treatment for a broad range of patients with liver-confined HCC.

Chemoembolization Adopting Polyethylene Glycol Drug-Eluting Embolics Loaded With Doxorubicin for the Treatment of Hepatocellular Carcinoma.

OBJECTIVE: The purpose of this study is to determine the efficacy and tolerability of transarterial chemoembolization (TACE) using polyethylene glycol (PEG) drug-elutable microspheres loaded with doxorubicin for treatment of hepatocellular carcinoma (HCC). SUBJECTS AND METHODS: Forty-two patients with unresectable HCC, as determined by a tumor board, were assigned to undergo TACE and were treated with PEG drug-elutable embolics loaded with doxorubicin. Patients were prospectively enrolled and included 32 (76%) men and 10 (24%) women. Their median age was 65 years (range, 42-83 years). Patients were treated with 50 mg of doxorubicin loaded in 2 mL of PEG embolics (mean [± SD] diameter, 100 ± 25 µm) that were infused via a chemoembolization method. Data collected included previous cancer therapy, tumor size, number of lesions, history of TACE, tumor response (at 1, 3, and 6 months), type and intensity of adverse events, and quality of life (QOL) analysis. RESULTS: One month after TACE, the overall tumor response rate was 79% (50% complete response, 29% partial response, 17% stable disease, and 5% progressive disease). At 3 months, the rates were 48% for complete response, 24% for partial response, 24% for stable disease, and 3% for progressive disease. At 6 months, the rates were 43% for complete response, 19% for partial response, 29% for stable disease, and 10% for progressive disease. TACE was well tolerated by all patients, with no evidence of procedure-related complications or systemic drug-related adverse events. Fever (33%), increase in transaminase level (17%), and pain (33%) were the most frequent adverse events, and their intensity was mostly mild (grades 1 and 2). The QOL scores were 80 at 1 month, 81 at 3 months, and 82 at 6 months after TACE. CONCLUSION: These data suggest that PEG embolics are efficacious and safe for the treatment of HCC, as indicated by their good tolerability, QOL scores, and high tumor response.

Transarterial chemoembolization with DC Bead LUMI™ radiopaque beads for primary liver cancer treatment: preliminary experience.

AIM: Primary objectives of the study were to assess the safety of transarterial chemoembolization (TACE) using DC Bead LUMI™ for the treatment of hepatocellular carcinoma and beads distribution after TACE. PATIENTS/METHODS: This was a prospective observational cohort study. The study included 44 hepatocellular carcinoma patients who were treated with TACE using DC Bead LUMI. Beads distribution was monitored 1 h after TACE by CT scan. RESULTS: TACE had no intraprocedural complications. Observed side effects were of mild intensity and included pain in 5 (11%), fever in 4 (9%) and vomiting in 2 (5%) patients. Most patients (89%) reported no adverse event. Non-target distribution was observed in only two cases (5%). CONCLUSION: DC Bead LUMI allowed assessing in real time their distribution. This could prevent non-target infusion and reduce toxicity.

Does Locoregional Chemotherapy Still Matter in the Treatment of Advanced Pelvic Melanoma?

Pelvic Melanoma relapse occurs in 15% of patients with loco regional metastases, and 25% of cases do not respond to new target-therapy and/or immunotherapy. Melphalan hypoxic pelvic perfusion may, therefore, be an option for these non-responsive patients. Overall median survival time (MST), stratified for variables, including BRAF V600E mutation and eligibility for treatments with new immunotherapy drugs, was retrospectively assessed in 41 patients with pelvic melanoma loco regional metastases. They had received a total of 175 treatments with Melphalan hypoxic perfusion and cytoreductive excision. Among the 41 patients, 22 (53.7%) patients exhibited a wild-type BRAF genotype, 11 of which were not eligible for immunotherapy. The first treatment resulted in a 97.5% response-rate in the full cohort and a 100% response-rate in the 22 wild-type BRAF patients. MST was 18 months in the full sample, 20 months for the 22 wild-type BRAF patients and 21 months for the 11 wild-type BRAF patients not eligible for immunotherapy. Melphalan hypoxic perfusion is a potentially effective treatment for patients with pelvic melanoma loco regional metastases that requires confirmation in a larger multicenter study.

Transarterial treatment of colorectal cancer liver metastases with irinotecan-loaded drug-eluting beads: technical recommendations.

Transcatheter hepatic arterial administration of irinotecan-loaded drug-eluting beads (DEBIRI) is used to treat liver-only or liver-dominant metastatic disease from colorectal cancer (CRC). Eligibility for DEBIRI should be established in each individual patient by a multidisciplinary team based on comprehensive clinical, imaging, and laboratory assessment. Standardization of DEBIRI technique and protocols would be expected to lead to improved efficacy and safety. The present article provides a set of technical recommendations for the use of DEBIRI in the treatment of hepatic CRC metastases.

Perioperative NALIRIFOX in patients with resectable pancreatic ductal adenocarcinoma: The open-label, multicenter, phase II nITRO trial.

BACKGROUND: Upfront surgery followed by postoperative treatment is a commonly adopted treatment for resectable pancreatic ductal adenocarcinoma (rPDAC). However, the risk of positive surgical margins, the poor recovery that often impairs postoperative treatments, and the risk of recurrence might limit the outcome of this strategy. This study evaluated the safety and the activity of liposomal irinotecan 50 mg/m2 + 5-fluorouracil 2400 mg/m2 + leucovorin 400 mg/m2 + oxaliplatin 60 mg/m2 (NALIRIFOX) in the perioperative treatment of patients with rPDAC. METHODS: Eligible patients had a rPDAC with < 180° interface with major veins' wall. Patients received 3 cycles before and 3 cycles after resection with NALIRIFOX, days 1 and 15 of a 28-day cycle. The primary endpoint was the proportion of patients undergoing an R0 resection. RESULTS: 107 patients began preoperative treatment. Nine patients discontinued the treatment because of related or unrelated adverse events. Disease-control rate was 92.9%. 87 patients underwent surgical exploration, 11 had intraoperative evidence of metastatic disease, and 1 died for surgical complications. R0 resection rate was 65.3%. 49 patients completed the three postoperative cycles. The most common grade ≥ 3 adverse events were diarrhea and neutropenia. Median overall survival (OS) of ITT patients was 32.3 months (95% CI 27.8-44.3). Median disease-free and OS from surgery of resected patients were 19.3 (95% CI 12.6-34.1) and 40.3 months (95% CI 29-NA), respectively. CONCLUSION: Perioperative NALIRIFOX was manageable and active, and deserves further investigation in randomized trials comparing it with standard upfront surgery followed by adjuvant therapy.

Transarterial chemoembolization alone or followed by bevacizumab for treatment of colorectal liver metastases.

AIMS: Bevacizumab (B) in association with systemic chemotherapy is commonly used for the treatment of colorectal cancer liver metastases. The aim of this study was to monitor tumor response, overall survival (OS) and progression-free survival (PFS) of patients with colorectal cancer liver metastases treated with transarterial chemoembolization (TACE) + B compared with TACE alone and to correlate the results with KRAS mutational status. PATIENTS & METHODS: This was an observational multicentric case-control study (NCT03732235) on the efficacy and safety of B administered after TACE. RESULTS: The disease control rate was significantly higher for the TACE + B than the TACE alone group (p < 0.001). KRAS wild-type patients had a significantly better disease control rate than those with KRAS mutations in the TACE + B group. Median OS and PFS were similar for the TACE + B and TACE groups, whereas median time to progression was significantly higher for the TACE + B group (p < 0.01). CONCLUSION: The combination of TACE with B may improve tumor response and delay disease progression.

Effectiveness and safety of oxaliplatin compared to cisplatin for advanced, unresectable gastric cancer: a systematic review and meta-analysis.

BACKGROUND: Cisplatin has been largely used in the treatment of advanced, unresectable gastric cancer, mainly in combinations with fluoropyrimidines and anthracyclines. Oxaliplatin has been shown to be at least as effective as cisplatin for this disease, but with less toxicity and a better tolerability profile, especially for older patients. We performed a systematic review of the literature to address and quantify differences in the efficacy and the safety between oxaliplatin and cisplatin for the treatment of this disease. METHODS: The literature was searched for randomized controlled trials (RCTs) comparing oxaliplatin to cisplatin. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to analyze dichotomous variables. Hazard ratios (HRs) for progression and death were combined with an inverse variance method based on logarithmic conversion. A fixed effect model and Mantel-Haenszel's (M-H) method were used. Heterogeneity was tested with the Q test and the I (2) value. Sensitivity analyses were performed. RESULTS: Three RCTs were identified, involving a total of 1294 patients. Oxaliplatin significantly improved progression-free survival (HR = 0.88, p = 0.02) and overall survival (HR = 0.88, p = 0.04). Moreover, it was associated with less neutropenia (OR = 0.53, p < 0.01) and fewer thromboembolic events (OR = 0.42, p < 0.01), but it was also associated with increased neurotoxicity (OR = 6.91, p < 0.01). CONCLUSIONS: Our results support the existence of a small but significant survival benefit of oxaliplatin over cisplatin. Oxaliplatin is associated with less toxicity and better tolerability, especially in older patients and when used in two-drug, bi-weekly regimens.

Recurrent retroperitoneal sarcomas: Clinical outcomes of surgical treatment and prognostic factors.

BACKGROUND AND PURPOSE: Locoregional recurrence after resection of primary retroperitoneal sarcoma (RPS) is a challenging therapeutic issue. The objective of this study was to identify clinicopathological factors predictive of overall survival (OS) and disease specific survival (DSS) after reoperation for recurrent RPS. PATIENTS AND METHODS: We retrospectively collected data from the medical records of 800 patients who underwent resection for sarcoma at our Institution, from 1983 to 2015. Among these patients, 120 were treated for retroperitoneal sarcoma and 55 had a locoregional recurrence (LR). Four of them did not undergo surgery and thus were excluded from this study leaving 51 cases available for data analysis. Univariate and multivariate survival analyses were performed to identify prognostic factors. RESULTS: Median overall survival was 33 months. The 1-year, 3-year and 5-year OS rates were 75.5%, 47.1% and 31.6% respectively. Multivariate Cox regression analysis suggested that extension of surgery (P = 0.026), surgical margin status (P = 0.015) and histological grade of recurrent tumor (P = 0.047) were independent prognostic factors for OS. Median DSS was 48 months. The 1-year, 3-year and 5-year DSS rates were 79.2%, 53.1% and 40.9%, respectively. At multivariate analysis, predictors of DSS were extension of surgery (P = 0.004), margin status (P = 0.011), histological grade of recurrent tumor (P = 0.008), and disease free interval (DFI) (P = 0.020). As regards histological subtype of recurrent RPS, at univariate analysis, well-differentiated liposarcoma (WDLS) was associated with better OS and DSS (P = 0.052 and P = 0.016 respectively) compared to dedifferentiated liposarcoma (DDLS). CONCLUSIONS: According to our findings, surgery is more beneficial in patients with low-grade sarcoma, WDLS and long DFI. The achievement of clear resection margins, rather than performing a multivisceral resection, appears to be a key factor to improve OS and DSS.

Circulating MicroRNA-21 and MicroRNA-122 as Prognostic Biomarkers in Hepatocellular Carcinoma Patients Treated with Transarterial Chemoembolization.

BACKGROUND: MicroRNAs (miRNAs) have been proposed as biomarkers in hepatocellular carcinoma (HCC). We aim at evaluating miR-21 and miR-122 in HCC patients treated with drug-eluting beads transarterial chemoembolization (DEB-TACE) as prognostic biomarkers and investigating their correlation with hypoxia inducible factor-1α (HIF-1α) serum levels. METHODS: In this retrospective study, 12 healthy subjects, 28 cirrhotics, and 54 HCC patients (tested before and four weeks after DEB-TACE) were included. Whole blood miR-21 and miR-122 levels were measured by quantitative real time (qRT)-PCR, while serum HIF-1α was assessed by an enzyme-linked immunosorbent assay (ELISA) test. RESULTS: The highest level of miR-21 was found in cirrhotics, while HCC patients had the highest level of miR-122 (which was even higher in "viral" HCC, p = 0.006). miR-21 ratio (after/before DEB-TACE) and miR-122 below their respective cut-offs identified patients with longer progression-free survival (p = 0.0002 and p = 0.02, respectively). The combined assessment of alpha-fetoprotein and miR-21 ratio, both independent prognostic predictors, identified early progressors among patients with complete or partial radiological response. miR-21 levels positively correlated with HIF-1α before (p = 0.045) and after DEB-TACE (p = 0.035). CONCLUSIONS: miR-21 ratio and miR-122 are useful prognostic markers after DEB-TACE. miR-21 correlates with HIF-1α and probably has a role in modulating angiogenesis in HCC.

The immune cell landscape of metastatic uveal melanoma correlates with overall survival.

BACKGROUND: Uveal melanoma (UM) represents the most common primary intra-ocular malignancy in adults. Up to 50% of the patients develop distant metastases within 10 years from diagnosis, with the liver as the most common site. Upon metastatization, life expectancy strongly reduces and immune checkpoint inhibitors that prove effective in cutaneous melanoma do not modify clinical outcome. To date, few studies have focused on deciphering the immunomodulatory features of metastatic UM microenvironment, and there are no prognostic models for clinical use. This highlights the urgent need to understand the delicate interplay between tumor and immune cells acting at the site of metastasis. METHODS: We collected a patient cohort comprising 21 metastatic UM patients. Hepatic and extra-hepatic UM metastasis samples were studied by multiplex immunofluorescence to assess the tumor immune cell composition. Quantitative analyses were performed to correlate immune cell densities with treatment response, metastasis site and patient survival. RESULTS: Compared to patients with progressive disease, those with controlled disease had a higher intra-tumoral/peritumoral ratio of CD8 + Granzyme B+ cells, higher density of intra-tumoral CD8+ cytotoxic T lymphocytes (CTL) and an increased percentage of UM cells in close proximity to T lymphocytes, reflecting a role of tumor-killing T cells in the disease. In liver metastases (LM), the intra-tumoral densities of CD163+ tumor-associated macrophages (TAM) and of total CD8+ T cells were higher than in extra-hepatic UM metastases, but the percentage of Granzyme B+ CTL was lower. Moreover, LM displayed more UM cells adjacent to both CTL and TAM, and also more T cells in proximity to TAM, all signs of an impaired immune response. The percentage of activated CTL within the tumor represented a prognostic indicator, as patients with a higher intra-tumoral percentage of CD8 + Granzyme B+ cells had the better outcome. A temptative Immunoscore was generated and proved capable to stratify patients with improved survival. Finally, CD4 + FoxP3+ T cells appeared a crucial population for response to immunotherapy. CONCLUSION: The results of this study underly the clinical relevance and functional importance of composition and localization of antitumor effector cells for the progression of UM metastasis.

Long-lasting response with metronomic capecitabine in advanced hepatocellular carcinoma.

Effective and safe systemic treatment for advanced hepatocellular carcinoma (HCC) with severe underlying cirrhosis is not yet available. Sorafenib, an oral multikinase inhibitor, has proved to be effective in the treatment of patients affected by HCC with Child-Pugh class A liver function. For patients with cirrhosis-associated HCC having Child-Pugh class B and C liver function, no systemic treatments of documented efficacy and safety exist. We report a case of metastatic HCC associated with Child-Pugh class B cirrhosis that was treated with low, "metronomic" doses of capecitabine (1000 mg/day continuously). This treatment was effective and well tolerated and the response was maintained for 18 months. Metronomic capecitabine may represent a possible alternative in the treatment of those patients with advanced cirrhosis-associated HCC who cannot be treated with sorafenib.

Updates of colorectal cancer liver metastases therapy: review on DEBIRI.

Colorectal cancer is a worldwide public health issue, presenting an advanced stage at diagnosis in more than 20% of patients. Liver metastases are the most common metastatic sites and are not indicated for resection in 80% of cases. Unresectable colorectal cancer liver metastases that are refractory to systemic chemotherapy may benefit from transarterial chembolization with irinotecan-loaded beads (DEBIRI). Several studies show the safety and efficacy of DEBIRI for the treatment of colorectal cancer liver metastases. The development of transarterial chembolization and the introduction of new embolics have contributed to better outcomes of DEBIRI. This article reviews the current literature on DEBIRI reporting its use, efficacy in terms of tumor response and survival and side effects.
