Metronomic chemotherapy with cyclophosphamide for the treatment of advanced hepatocellular cancer: A case report.

ABSTRACT:

Introduction and importance

Metronomic chemotherapy entails chronic, equally spaced administration of low doses of various chemotherapeutic drugs without extended rest periods. Its use as a second-line treatment in advanced or metastatic hepatocellular cancer remains under investigation.

Case presentation

We report a case of a 49-year-old Caucasian female patient with an enlarged (∼14 cm) hepatocellular cancer. In July 2016, she underwent right hepatectomy (after preceding TACE). During the follow-up period, she presented early disease recurrence with lung and peritoneal metastasis. Initially, she received an inhibitor of protein kinase (sorafenib) for six months without response. Afterwards, cyclophosphamide administration at low doses as metronomic chemotherapy provided complete regression of the metastatic lesions. The patient remains in good performance status almost 4 years after initial treatment, without signs of recurrence in her recent follow-up.

Clinical discussion

Using cyclophosphamide as metronomic chemotherapy in advanced hepatocellular cancer may have a promising antiangiogenic antitumor effect. Future clinical trials need to demonstrate this effect in terms of tumor suppression and increased disease-free survival.

Conclusion

Large multi-centered clinical trials have to be planned to investigate the precise role of cyclophosphamide in the therapy of hepatocellular cancer while defining the patients' profile that will benefit most from cyclophosphamide.

Project description:BackgroundReal-world data of the CM regimen [cyclophosphamide (CTX) plus methotrexate (MTX)] in metronomic pattern for advanced breast cancer is limited to small-sample or retrospective studies. This study was aimed to determine the effectiveness and safety of CM regimen in treating advanced breast cancer and to identify which patients are most likely to benefit from metronomic CM regimen.MethodsPatients with advanced breast cancer who received the metronomic CM regimen at least once between January 2009 and February 2019 in Sun Yat-sen University Cancer Center were included. Clinicopathological characteristics were collected. Overall survival (OS) and progression-free survival (PFS) were assessed using Kaplan-Meier estimates. Characteristics between patients with PFS < 6 months and ?6 months were compared using the Chi-square test. Univariate and multivariate Cox regression model was used to estimate the prognostic factors for PFS and OS.ResultsA total of 186 patients were included. The median age and follow-up were 49 years and 13.3 months, respectively. Over 50% of the patients were estrogen receptor/progesterone receptor-positive, and 60.8% had been heavily treated (?3 lines). The objective response rate was 3.8%, the disease control rate at 12 weeks was 41.4%, and the clinical benefit rate at 24 weeks was 31.2% (58/186). The median PFS was 4.0 months [95% confidence interval (CI): 3.6-4.7 months], the median duration of clinical benefit was 9.5 months (95% CI: 8.2-10.8 months), and the median OS was 26.8 months (95% CI: 20.9-37.7 months). Multivariate analysis for PFS revealed the CM regimen as maintenance therapy and no liver metastasis as favorable prognostic factors. Furthermore, patients without liver metastasis were more likely to have a PFS over 6 months than those with liver involvement (P = 0.022). Liver, lymph node, and brain metastases were unfavorable prognostic factors for OS. The CM regimen was well-tolerated without newly reported adverse events.ConclusionsThe CM regimen was effective in selected patients. In clinical practice, it would be better used as maintenance therapy and in patients without liver metastasis. Further follow-up investigation should be performed to examine its effect when used in combination with other treatments and determine predictive biomarkers.

Project description:IntroductionVaccination with dendritic cells (DCs) has generally not fulfilled its promise in cancer immunotherapy due to ineffective translation of immune responses into clinical responses. A proposed reason for this is intrinsic immune regulatory mechanisms, such as regulatory T cells (Tregs). A metronomic regimen of cyclophosphamide (mCy) has been shown to selectively deplete Tregs. To test this in a clinical setting, we conducted a phase I trial to evaluate the feasibility and safety of vaccination with DCs transfected with mRNA in combination with mCy in patients with metastatic malignant melanoma (MM). In addition, clinical and immunological effect of the treatment was evaluated.Experimental designTwenty-two patients were enrolled and treated with six cycles of cyclophosphamide 50 mg orally bi-daily for a week every second week (day 1-7). During the six cycles patients received at least 5 × 106 autologous DCs administered by intradermal (i.d.) injection in the week without chemotherapy. Patients were evaluated 12 and 27 weeks and every 3rd mo thereafter with CT scans according to RECIST 1.0. Blood samples for immune monitoring were collected at baseline, at the time of 4th and 6th vaccines. Immune monitoring consisted of IFNγ ELISpot assay, proliferation assay, and flow cytometry for enumeration of immune cell subsets.ResultsToxicity was manageable. Eighteen patients were evaluable after six cycles. Of these, nine patients had progressive disease as best response and nine patients achieved stable disease. In three patients minor tumor regression was observed. By IFNγ ELISpot and proliferation assay immune responses were seen in 6/17 and 4/17 patients, respectively; however, no correlation with clinical response was found. The percentage of Tregs was unchanged during treatment.ConclusionTreatment with autologous DCs transfected with mRNA in combination with mCy was feasible and safe. Importantly, mCy did not alter the percentage of Tregs in our patient cohort. There was an indication of clinical benefit; however, more knowledge is needed in order for DCs to be exploited as a therapeutic option.
