Chemosensitivity in vitro and its correlation with clinico-pathological parameters of patients with breast cancer / 肿瘤研究与临床

ABSTRACT

Objective To detect any association between chemosensitivity of tumor in vitro and clinico-pathological characteristics of patients with breast cancer, such as age, pathological type, pathological grade, as well as local lymph nodal status. Methods Sixty patients with breast cancer were tested with tissue culture-end point staining-computer image analysis (TECIA) after resection of the primary lesion or biopsy. Their chemosensitivity to seven common anticancer drugs were evaluated, which were fluorouracil (5-Fu), vinorelbine(NVB), cisplatin(DDP), paclitaxel(TAX), docetaxel(TAT), doxorubicin(ADM) and epirubicin(EADM). Results 31.67% of the total 60 specimens were resistant to all of 7 drugs. The sensitive rate of the tissues to a specific drugs was 60.00 % (36/60) for EADM, 54.00 %(32/60) for NVB, 36.00 %(22/60) for DDP or TAT, 30.00 %(18/60) for TAX, 26.00 %(16/60) for 5-Fu and 16.00 %(10/60) for ADM in turn. The sensitive rate of invasive carcinoma group was higher than non-invasive carcinoma group (74.47 % vs 46.15 %, P< 0.05), and grade Ⅲ group higher than grade Ⅰ or grade Ⅱ group (90.91% vs 54.55 %, 90.91% vs 55.56%, P<0.01). The differences of sensitive rates among three different age groups and between two groups with/ without lymph nodal metastasis were not significant statistically (P > 0.05). Conclusion The total sensentive rate of breast cancer might be relatively high to EADM, NVB and TAT, and TECIA could be an important reference for clinical individual chemotherapy.
