Deskripsi
Background: Carcinoma breast is most commonly diagnosed cancer at present. Due to systemic nature of disease, chemotherapy plays an important role in treatment of carcinoma breast. Relapse (loco-regional or metastatic) is not uncommon in this disease. Both eribulin and capecitabine are effective as single agent in relapsed disease. In this single-institutional retrospective study, eribulin and capecitabine have been used as combination chemotherapy regimen in patients with relapsed carcinoma breast. Marerials and methods: Patients diagnosed to have relapsed carcinoma of breast, who were ER and/or PR positive, Her-2/neu negative or triple negative and received eribulin alongwith capecitabine, were included in our study. Primary objective of this study was to assess response, progression-free survival (PFS) and overall survival (OS). Secondary objective was toxicity assessment. Results: 48 patients were included in our study. Median age of patients was 56 years. Thirty six (75%) patients had ER and/or PR positive status and twelve (25%) patients had ER/PR negative status. Five (10.4%) patients achieved complete response (CR). Thirty two (66.7%) patients achieved partial response (PR). Disease was stable (SD) in nine (18.8%) patients. Two (4.2%) patients suffered from progressive disease (PD). Median Progression-free survival (PFS) was 10.15 months. Mean of PFS of patients was 10.72 (95% CI- 9.72-11.72) months. Median overall survival (OS) was 18.15 months. Mean of overall survival of patients was 19.56 (95% CI- 17.9-21.22) months. Nineteen (39.6%) and three (6.2%) patients experienced grade 2 and grade 3 anemia respectively. Eighteen (37.5%) and two (4.2%) patients suffered from grade 2 and grade 3 neutropenia respectively. One patients experienced grade 2 thrombocytopenia. Nineteen (39.6%) patients experienced grade 2 diarrhoea. One patients suffered from grade 3 diarrhoea. Palmo-plantor erythrodysesthesia was seen in eight (16.7%) patients. Six (12.5%) patients suffered from grade 2 neuropathy. Two (4.2%) patients experienced grade 3 neuropathy. Fatigue was seen in 19 (39.6%) patients. Conclusion: Eribulin alongwith capectabine can be used in patients with relapsed carcinoma breast, in whom anthracycline and taxane have previously been used; with response rate and survival better than either single agent chemotherapy. This regimen is important particularly for TNBC, where option for chemotherapy is limited.
