Abstract:
Objective To explore the levels of leptin(LEP) and soluble leptin receptor (sOB‐R) in breast cancer patients′ser‐um ,and to discuss the relationship between LEP ,sOB‐R ,free leptin index(FLI) and the patients′clinical pathologic features .Meth‐ods 70 serum specimens of breast cancer patients who confirmed by pathological diagnosis were collected before the surgery ,the serum of benign breast disease group(n=50) and normal group(n=50) were also collected as control .The levels of LEP and sOB‐Rinserumweredetected,andtheresultafterbodymassindex(BMI)correctionwereanalyzed.Finally,therelationshipbetweenthe expression of LEP ,sOB‐R and clinical pathologic features were analyzed .Results The serum level of LEP in breast cancer group was highly increased than the other two groups (P<0 .05) ,and sOB‐R was reduced(P<0 .05) .After BMI correction ,LEP was still highly increased(P<0 .05) ,but sOB‐R was no significant difference (P>0 .05) .The level of LEP in the postmenopausal breast cancer patients were highly increased than menopause patients (P>0 .05) ,and the expression of LEP in cancer group were signifi‐cant higher than two control groups by both postmenopausal and menopause (P>0 .05) .The result suggested the serum level of LEP and FLI are associated with pTNM stages and lymph node metastases (P<0 .05) ,and elevated level of LEP in postmenopausal patients had differences in pTNM stages and lymph node metastases (P< 0 .05) .Conclusion The serum LEP level and the FLI may be potential indicators to evaluate the prognosis of the patient with breast cancer .The serum LEP may promoted the process of the postmenopausal patients of breast cancer .
