The outcome for women with microinvasive cervical cancer with stromal invasion 1 mm or less: should we always re-excise?

ABSTRACT

To assess the management and outcome for women with microinvasive cervical cancer with stromal invasion 1 mm or less, examining the impact of re-excision. A retrospective cohort study with interval analysis performed between December 2000 and December 2010. Sheffield Gynaecological Cancer Centre and Jessop Wing Colposcopy Unit, Sheffield, UK. Women diagnosed with microinvasive cervical cancer with stromal invasion 1 mm or less during the allocated study period. Methods used is a retrospective cohort study. Risk of recurrence and mortality from disease; incidence of residual disease in repeat excision specimens. A total of 140 women were identified as having microinvasive cervical cancer with stromal invasion 1 mm or less. Sixty-three (45%) had a completely excised lesion; 77 (55%) had an incompletely excised lesion at first treatment. Fifty-five women underwent repeat excision. No residual disease was found in the majority (n=40; 73%). No women suffered disease recurrence or died from disease during the allocated study period. Outcome for women with microinvasive cervical cancer with stromal invasion 1 mm or less is excellent. Repeat excision is associated with very low rates of residual disease. A more conservative approach to follow-up incorporating HPV testing should be explored.
