Carcinoma microinvasors are frequently found in the records of ductal carcinoma in situ (DCIS) cases, a factor that may favor non-effective treatment. Survival differs in cases of microinvasion due to the possibility of metastasis. Purpose: was to characterize cases of microinvasive carcinoma transcribed as in situ and subsequent comparison of survival of these cases in relation to cases of DCIS. Methods: We used a secondary database of the Registry of Cancer Population Base of Goiânia and data of the city hall of that city. Results: The mean size of the microinvasive lesions associated with DCIS was 1.3 cm, with foci of invasion <1.0mm, the majority of the positivity for estrogen and progesterone receptors corresponded to 28.6% and for HER2 14, 3%. In addition, 33% of these cases had impaired margins. Conclusion: attention different from DCIS should be given to microinvasive carcinoma with regard to registration and diagnosis.
