Abstract: Objective To investigate the impact of squamous cell carcinoma antigen(SCCAg)in patients with recurrent squamous cell carcinoma of the uterine cervix.Methods Totally 72 patients with recurrent squamous cell carcinoma of the uterine cervix treated at the Cancer Hospital,Peking Union Medical College,Chinese Academy of Medical Sciences,between 1999 and 2005 were retrospectively analyzed to investigate the impact of SCCAg on diagnosis and prognosis by univariate and multivariate analysis.Results This study included 30 patients with recurrent disease after primary radical surgery and 42 patients with recurrent cervical cancer after radio-chemotherapy.Sixty one patients(85%)had serum SCCAg elevated (≥1.5 pg/L),and 20 of these(28%)had an increase of SCCAg before clinical manifestation of relapse.The median leading time was 3 months(range:1-13 months).Forty five patients had no symptoms with only SCCAg elevation,and 15 patients experienced leg edema and(or)sciatic pain,7 patients suffered from irregular bleeding and 5 patients had symptoms resulting from distant metastasis.Thirty three patients were diagnosed by histology biopsy and (or) cytology,39 patients were diagnosed with SCCAg elevation and clinical and radiological examinations,29 of these patients were diagnosed only by SCCAg elevation and CT or MRI.Fourteen patients recurred limited to the cervix or to the cervix and adjacent tissues(central recurrence),31 cases recurred at pelvis,and 20 patients with distant metastasis and 7 patients suffered from Pelvic recurrence and distant metastasis.Twenty three cases received salvage therapy including surgery for patients recurring after definitive radiotherapy and radiotherapy and or conform radiotherapy for patients after primary radical surgery,46 patients were given palliative chemotherapy and or radiotherapy,and 3 patients refused any treatment.The median and mean survival time were 11 months and 23 months respectively(2-62 months).The 3-year,5-year overall survival rate were 25%and 19%respectively.Univariate analysis showed SCCAg elevation before primary treatment,grade,recurrent site,treatment method,SCCAg≥10pg/L,SCCAg elevation during treatment,and SCCAg not within normal after treatment were correlated with 3-year survival rate.Twenty patients had an increase of SCCAg before clinical manifestation of relapse compared with other patients who did not,and the 3-year survival rate was not significantly different (22% vs 27%). Multivariate analysis revealed that only grade and treatment methods were independent risk factors. Conclusion The impact of the SCCAg in recurrent squamous cell carcinoma of the uterine cervix needs further study.
