Hepatic arterial infusion chemotherapy for extensive liver metastases of breast cancer: efficacy, safety and prognostic parameters

Simultaneous curative resection may improve the long-term survival of patients diagnosed with colorectal liver metastases: A propensity score-matching study

BACKGROUND

The benefit of simultaneous curative resection in patients with colorectal liver metastases has been unclear. Adjuvant chemotherapy is still considered an effective and priority treatment for advanced-stage colorectal patients.

METHODS

We retrospectively collected patients with colorectal liver metastases from January 2012 to October 2023 at the Guangxi Medical University Cancer Hospital. The baseline information was compared between a simultaneous curative resection group and a palliative treatment group. Propensity score matching with a 1:1 ratio was applied to develop comparable cohorts of curative resection and palliative treatment resection. Kaplan-Meier survival and Cox regression analyses were performed to determine the impact of curative resection on survival of colorectal liver metastasis patients. Prognostic nomogram and a web-version calculator were developed based on the multivariate Cox regression method. Then, the concordance index (C-index), receiver operating characteristic, calibration plots, and decision curves analysis were applied to evaluate the prognostic performance of the nomogram.

RESULTS

A total of 716 patients with colorectal liver metastases were enrolled in the study, of whom 131 patients received curative resection. There was no significant difference in terms of baseline information between the curative resection group and the palliative treatment group after propensity score matching. Multivariable Cox regression analysis showed that curative resection was an independent prognostic factor affecting overall survival (P = .001, hazard ratio = 1.95, 95% confidence interval 1.30-2.91). Compared with patients who did not receive curative resection, patients who received simultaneous curative resection had a significant improvement in overall survival before and after propensity score matching (P < .0001 and P = .0047, respectively). Overall survival nomogram showed excellent predictive performance with the C-indexes of 0.686 (95% confidence interval 0.556-0.792). The areas under the receiver operating characteristic curves were 0.75 (95% confidence interval 64.43-96.05), 0.75 (67.22-82.58), and 0.76 (66.10-85.98) for predicting 1-, 3-, and 5-year survival, respectively. The calibration plots and decision curves analysis also indicated the good predictability of the predictive nomogram. Finally, subgroup analysis further demonstrated a favorable impact of curative resection on overall survival in colorectal liver metastasis patients after propensity score matching.

CONCLUSIONS

Simultaneous curative resection may improve the overall survival of patients with colorectal liver metastases and is an independent and effective indicator for predicting overall survival. The nomogram may provide a personalized treatment strategy.

Anthracycline-based hepatic arterial infusion chemotherapy achieved 17 months of disease regression in a patient with breast cancer liver metastases resistant to multiple systemic chemotherapies

Hepatic arterial infusion chemotherapy (HAIC) for liver metastases (LMs) from breast cancer is not a standard of care, but its effectiveness in patients with extensive LMs who cannot tolerate systemic therapy has been reported. Herein, we report a case of breast cancer LMs that were controlled by anthracycline-based HAIC. A 46-year-old woman with estrogen receptor-positive, human epidermal growth factor receptor 2-negative metastatic breast cancer who had multiple LMs and bone metastases underwent seven lines of systemic therapy (paclitaxel/bevacizumab for 38 months; letrozole, nivolumab/fulvestrant, eribulin, gemcitabine/vinorelbine, high-dose toremifene/abemaciclib, and capecitabine for 21 months in total). However, owing to its adverse effects and the continued progression of the LMs, systemic therapy was switched to HAIC (40 mg/body epirubicin on day 1, 4 mg/body mitomycin C on days 1 and 15, and 500 mg/body 5-fluorouracil on days 1, 8, and 15; 28-day courses). In response to HAIC, the LMs remarkably regressed and were controlled for 17 months without severe adverse effects. HAIC was stopped when multiple brain metastases arose, and the patient died 2 months later. This case suggests that HAIC is a reasonable option for patients with extensive LMs, even in the late stage of treatment. HAIC recipients should be carefully selected through multidisciplinary discussions as the survival benefits of HAIC over systemic treatment remain unclear. Our findings identify a potential window for the use of traditional chemotherapeutic agents such as anthracyclines. Novel strategies to improve drug delivery are warranted in the future.

Locoregional Therapies for Primary and Metastatic Breast Cancer: AJR Expert Panel Narrative Review

Minimally invasive locoregional therapies have a growing role in the multidisciplinary treatment of primary and metastatic breast cancer. Factors contributing to the expanding role of ablation for primary breast cancer include earlier diagnosis, when tumors are small, and increased longevity of patients whose condition precludes surgery. Cryoablation has emerged as the leading ablative modality for primary breast cancer owing to its wide availability, the lack of need for sedation, and the ability to monitor the ablation zone. Emerging evidence suggests that in patients with oligometastatic breast cancer, use of locoregional therapies to eradicate all disease sites may confer a survival advantage. Evidence also suggests that transarterial therapies-including chemoembolization, chemoperfusion, and radioembolization-may be helpful to some patients with advanced liver metastases from breast cancer, such as those with hepatic oligoprogression or those who cannot tolerate systemic therapy. However, the optimal modalities for treatment of oligometastatic and advanced metastatic disease remain unknown. Finally, locoregional therapies may produce tumor antigens that in combination with immunotherapy drive anti-tumor immunity. Although key trials are ongoing, additional prospective studies are needed to establish the inclusion of interventional oncology in societal breast cancer guidelines to support further clinical adoption and improved patient outcomes.

Incidence and survival outcomes of secondary liver cancer: a Surveillance Epidemiology and End Results database analysis

Background

The global incidence and mortality rates of liver cancer, which is the second leading cause of cancer-related deaths worldwide, are increasing. However, information on its epidemiology and clinical prognosis is limited. This study aimed to characterize the epidemiology and prognostic factors of secondary liver cancer to aid in the pretreatment evaluation of the disease.

Methods

Patients diagnosed with secondary liver cancer between 2010 and 2014 in the Surveillance, Epidemiology, and End Results (SEER) database were retrospectively included. Kaplan-Meier analysis and Multivariate Cox regression analysis were performed to screen for significant factors associated with secondary liver cancer.

Results

A total of 85,738 secondary liver cancer patients were identified; in this population, the first primary site was the lung (25.9%), followed by the colorectum, pancreas, stomach, breast, and cecum. Patients with primary tumors of the colorectum, cecum and breast had longer median survival time. Advanced age, male gender, black race, poor differentiation or lack of differentiation, regional lymph node metastases, and presence of distant metastasis were associated with poor prognosis.

Conclusions

In this study, novel findings on the role of the primary site and synchronous distant metastasis to specific organs in patients with secondary liver cancer were described. These findings have significant implications in clinical diagnosis and treatment, and provide a better understanding of secondary liver cancer in the general population.

Successful Treatment with Hepatic Arterial Infusion Chemotherapy in a Breast Cancer Patient with Multiple Liver Metastases Who Declined Systemic Therapy

Despite improvements in systemic medical therapy (ST), liver metastases (LMs) are a poor prognostic factor in metastatic breast cancer (MBC) patients. We describe a MBC patient with predominant LMs treated with hepatic arterial infusion chemotherapy (HAIC) who declined ST. Moreover, we assessed general health status during treatment using C-reactive protein (CRP)/albumin ratio (CAR) and peripheral platelet count × CRP multiplier (P-CRP), well-known indicators of systemic inflammatory response. A 64-year-old woman who underwent a total mastectomy with axillary lymph node dissection for an HR-positive, HER2-negative infiltrating ductal BC developed multiple liver, lung, lymph node, and bone metastases. She received ST including paclitaxel plus the anti-vascular endothelial growth factor antibody, bevacizumab, hormone therapy with high-dose toremifene, the oral 5-fluorouracil derivative, S-1, and eribulin. She then declined ST because of the toxicity or decreased treatment motivation thereof, and opted for HAIC with 5FU plus epirubicin followed by Taxane for 1 year and 1 month. Computed tomography revealed a partial response or stable disease in the liver and slow progression in other sites without symptoms or side effects and decreased CEA and CA15-3 levels. The CAR and P-CRP remained low. She survived for 1 year and 3 months after the start of HAIC. This case reveals that HAIC may be an option for advanced BC patients with LMs who cannot receive ST.

Intra-Arterial Therapies for Liver Metastatic Breast Cancer: A Systematic Review and Meta-Analysis

PURPOSE

Performing a systematic review and meta-analysis to assess the evidence of intra-arterial therapies in liver metastatic breast cancer (LMBC) patients.

METHODS

A systemic literature search was performed in PubMed, EMBASE, SCOPUS for studies regarding intra-arterial therapies in LMBC patients. Full text studies of LMBC patients (n ≥ 10) published between January 2010 and December 2020 were included when at least one outcome among response rate, adverse events or survival was available. Response rates were pooled using generalized linear mixed models. A weighted estimate of the population median overall survival (OS) was obtained under the assumption of exponentially distributed survival times.

RESULTS

A total of 26 studies (1266 patients) were included. Eleven articles reported on transarterial radioembolization (TARE), ten on transarterial chemoembolization (TACE) and four on chemo-infusion. One retrospective study compared TARE and TACE. Pooled response rates were 49% for TARE (95%CI 32-67%), 34% for TACE (95%CI 22-50%) and 19% for chemo-infusion (95%CI 14-25%). Pooled median survival was 9.2 months (range 6.1-35.4 months) for TARE, 17.8 months (range 4.6-47.0) for TACE and 7.9 months (range 7.0-14.2) for chemo-infusion. No comparison for OS was possible due to missing survival rates at specific time points (1 and 2 year OS) and the large heterogeneity.

CONCLUSION

Although results have to be interpreted with caution due to the large heterogeneity, the superior response rate of TARE and TACE compared to chemo-infusion suggests first choice of TARE or TACE in chemorefractory LMBC patients. Chemo-infusion could be considered in LMBC patients not suitable for TARE or TACE.

Hepatectomy, RFA, and Other Liver Directed Therapies for Treatment of Breast Cancer Liver Metastasis: A Systematic Review

Background

The liver is the second most common site of breast cancer metastasis. Liver directed therapies including hepatic resection, radiofrequency ablation (RFA), transarterial chemo- and radioembolization (TACE/TARE), and hepatic arterial infusion (HAI) have been scarcely researched for breast cancer liver metastasis (BCLM). The purpose of this review is to present the known body of literature on these therapies for BCLM.

Methods

A systematic review was performed with pre-specified search terms using PubMed, MEDLINE, EMBASE, and Cochrane Review resulting in 9,957 results. After review of abstracts and application of exclusion criteria, 51 studies were included in this review.

Results

Hepatic resection afforded the longest median overall survival (mOS) and 5-year survival (45 mo, 41%) across 23 studies. RFA was presented in six studies with pooled mOS and 5-year survival of 38 mo and 11–33%. Disease burden and tumor size was lower amongst hepatic resection and RFA patients. TACE was presented in eight studies with pooled mOS and 1-year survival of 19.6 mo and 32–88.8%. TARE was presented in 10 studies with pooled mOS and 1-year survival of 11.5 mo and 34.5–86%. TACE and TARE populations were selected for chemo-resistant, unresectable disease. Hepatic arterial infusion was presented in five studies with pooled mOS of 11.3 months.

Conclusion

Although further studies are necessary to delineate appropriate usage of liver directed therapies in BCLM, small studies suggest hepatic resection and RFA, in well selected patients, can result in prolonged survival. Longitudinal studies with larger cohorts are warranted to further investigate the effectiveness of each modality.

Hepatic Arterial Infusion Chemotherapy for Metastatic Breast Cancer Patients With Resistance to Standard Systemic Chemotherapies

BACKGROUND/AIM

Hepatic arterial infusion chemotherapy (HAIC) is a treatment option for metastatic breast cancer (MBC) patients with extensive liver metastasis (LM); however, the appropriate regimen and the treatment effects have not been discussed. The aim of this study is to evaluate the efficacy and safety of HAIC with the 5-FU, epirubicin, and mitomycin-C (FEM) regimen.

PATIENTS AND METHODS

We reviewed MBC patients with critical LM who were resistant to standard systemic chemotherapies and had received HAIC with an FEM regimen.

RESULTS

We identified 57 patients who received HAIC between 2003 and 2017. The patient characteristics were as follows: i) median age=56 (30-80), and ii) Eastern Cooperative Oncology Group Performance Status, 0/1/2=43/11/3. The median number of LMs was 8 (range 1 to ≥20), the median diameter of LM was 5.2 cm (range=1.6 to 20.1). The median overall survival from the initiation of HAIC was 11.3 months (95% confidence interval=8.5-15.6). The objective response rate of LM was 63%.

CONCLUSION

HAIC with an FEM regimen is an effective salvage treatment for MBC patients with advanced LM.

Prognostic factors and survival according to tumor subtype in newly diagnosed breast cancer with liver metastases: A competing risk analysis

Population-based study for predicting the prognosis for breast cancer liver metastasis (BCLM) is lacking at present. Therefore, the present study aimed to evaluate newly diagnosed BCLM patients of different tumor subtypes and assess potential prognostic factors for predicting the survival for BCLM patients. Specifically, data were collected from the Surveillance, Epidemiology and End Results program from 2010 to 2014, and were assessed, including the data of patients with BCLM. Differences in the overall survival (OS) among patients was compared via Kaplan-Meier analysis. Other prognostic factors of OS were determined using the Cox proportional hazard model. In addition, the breast cancer-specific mortality was assessed using the Fine and Gray's competing risk model. A nomogram was also constructed on the basis of the Cox model for predicting the prognosis of BCLM cases. A total of 2,098 cases that had a median OS of 20.0 months were included. The distribution of tumor subtypes was as follows: 42.2% with human epidermal growth factor receptor 2 (Her2; -)/hormone receptor (HR; +), 12.8% with Her2(+)/HR(−), 19.1% with Her2(+)/HR(+) and 13.5% with triple negative breast cancer (TNBC). Kaplan-Meier analysis revealed that older age (>64 years), unmarried status, larger tumor, higher grade, no surgery, metastases at other sites, and TNBC subtype were associated with shorter OS. Additionally, multivariate analysis revealed that older age (>64 years), unmarried status, no surgery, bone metastasis, brain metastasis and TNBC subtype were significantly associated with worse prognosis. Thus, age at diagnosis, marital status, surgery, bone metastasis, brain metastasis and tumor subtype were confirmed as independent prognosis factors from a competing risk model. We also constructed a nomogram, which had the concordance index of internal validation of 0.685 (0.650–0.720). This paper had carried out the population-based prognosis prediction for BCLM cases. The survival of BCLM differed depending on the tumor subtype. More independent prognosis factors were age at the time of diagnosis, surgery, marital status, bone metastasis, as well as brain metastasis, in addition to tumor subtype. Notably, the as-constructed nomogram might serve as an efficient approach to predict the prognosis for individual patients.

Intra-arterial Mitomycin C infusion in a large cohort of advanced liver metastatic breast cancer patients: safety, efficacy and factors influencing survival

PURPOSE

The aim of this study was to determine the safety and efficacy of Mitomycin C (MMC) infusion in a large cohort of advanced liver metastatic breast cancer patients (LMBC) and to determine factors influencing overall survival (OS).

METHODS

We retrospectively analysed LMBC patients, treated with MMC infusion between 2000 and 2017. Hepatic response was measured with baseline CT scans and first available CT scan after MMC infusion by RECIST 1.1 criteria. Adverse events were registered by the CTCAE version 5.0. OS and hepatic progression free survival (hPFS) were evaluated using Kaplan-Meier estimates. After univariable analysis, a stepwise forward multivariable (MV) prediction analysis was developed to select independent pre-treatment factors associated with OS.

RESULTS

We included 176 patients with a total of 599 MMC infusions, mostly heavily pre-treated patients with a median time from diagnosis of MBC to MMC infusion of 36.9 months. RECIST evaluation of liver lesions (n = 132) showed a partial response rate of 15%, stable disease of 43% and progressive disease in 17%. Adverse events grade 3 and 4 were reported in 17.5%. Median PFS was 5.5 months and median OS was 7.8 months. Significant independent baseline predictors of worse OS included number of prior systemic chemotherapy lines, prior liver ablation, higher liver tumour burden and elevated levels of bilirubin and ALT.

CONCLUSION

MMC infusion is safe and effective in advanced LMBC patients. An increased number of prior therapies, a higher liver tumour burden and elevated levels of bilirubin and ALT were associated with a worse OS.

Hepatic Arterial Infusion Chemotherapy Is a Feasible Treatment Option for Breast Cancer with Liver-predominant Metastatic Disease

BACKGROUND

Patients with liver metastasis from breast cancer (LMBC) are usually offered systemic therapy. However, for those with progressive liver disease and limited extra-hepatic conditions, local liver management becomes an option. Herein we present our experience with hepatic arterial infusion chemotherapy (HAIC).

PATIENTS AND METHODS

From 1999 to 2018, 42 patients with LMBC, who had progressive liver metastasis after systemic therapy, were treated with HAIC. A catheter was placed angiographically into the hepatic artery and remained there for 5 consecutive days. One cycle of chemotherapy consisted of mitoxantrone, 5-fluorouracil, folinic acid, and cisplatin. This treatment was repeated at monthly intervals. The medical records were reviewed and analyzed for hepatic tumor response, progression-free survival, overall survival and adverse effects.

RESULTS

Complete response was observed in two patients (5%), partial response in 18 patients (43%) and stable disease in eight patients (19%). Fourteen patients (33%) had progressive disease after HAIC. The median progression-free survival and overall survival were 8.4 and 19.3 months, respectively. There was no death related to HAIC. The patients with response to the treatment had a significant survival benefit (p<0.005).

CONCLUSION

HAIC can be an option for those with progressive liver disease who are heavily pretreated while their extra-hepatic conditions are minimal or stable.

A phase I clinical trial of hepatic arterial infusion of oxaliplatin and oral capecitabine, with or without intravenous bevacizumab, in patients with advanced cancer and predominant liver involvement

BACKGROUND

We investigated hepatic arterial infusion (HAI) oxaliplatin combined with capecitabine +/- bevacizumab in advanced cancer with predominant liver involvement.

METHODS

Patients received HAI oxaliplatin (140 mg/m²) and escalating doses of capecitabine (500, 750, and 1000 mg/m²), with (Group 1) or without (Group 2) bevacizumab (10 mg/kg IV). A 3 + 3 dose design was used, followed by an expansion phase.

RESULTS

From 9/2009 to 2/2014, 61 patients (34 men, 27 women) were enrolled (Group 1 = 44; Group 2 = 17). Patients were treated in Group 2 if they had contraindications to bevacizumab (n = 13) or if there was no opening in Group 1 (n = 4). The median age was 60 years (range, 20-88). The most common cancers were colorectal (22 patients), liver (12), pancreatic (7), breast (4), and biliary tract (4). The median number of prior therapies was 3 (range, 1-12); 32 (53%) patients had received oxaliplatin. The dose-limiting toxicity was Grade 3 diarrhea and occurred in 2 patients receiving 1000 mg/m² capecitabine. The maximum tolerated dose was HAI oxaliplatin 140 mg/m², capecitabine 750 mg/m², and bevacizumab 10 mg/kg. The most common toxicities were nausea/vomiting, anemia, thrombocytopenia, neutropenia, and hypomagnesemia. The rates of partial response and stable disease ≥ 4 months were 22% and 39% (Group 1) and 9% and 0% (Group 2). The respective median time to treatment failure and overall survival were 3 and 6.9 months (Group 1) and 1.5 and 5.9 months (Group 2).

CONCLUSION

HAI oxaliplatin combined with capecitabine +/- bevacizumab was well-tolerated and was associated with favorable outcomes in selected patients.
