OBJECTIVE:

The aim of this study was to evaluate the clinicopathological features of minimal deviation adenocarcinoma (MDA) and to analyze its prognostic factors.

METHODS:

We retrospectively analyzed the medical records of 17 patients who were diagnosed with MDA at a single institution between January 2005 and December 2015.

RESULTS:

The median age of the patients was 47.7 years (33–75 years). MDA was diagnosed in 7 patients (41.2%) before performing definitive surgery. Stage IB disease was diagnosed in 12 patients (70.6%) and advanced stage disease (stage II 3, stage III 2) in 5. MDA was incidentally diagnosed following hysterectomy for benign conditions in 6 patients. Adjuvant therapy was administered to 13 patients (76.5%). During median follow-up over 33.6 months (7–99 months), 11 patients (64.7%) showed no evidence of disease, 6 (35.3%) showed persistent or recurrent disease and 5 died of the disease. Peutz-Jeghers syndrome was not suspected in any patient, and no mutation was detected in the 3 patients who underwent genetic testing. Univariate analysis showed that advanced stage disease (P=0.016) and lymphovascular space invasion (P=0.002) demonstrated a statistically significant association with poor overall survival (OS) rates. Advanced stage disease continued to show a significant association with poor OS rates (hazard ratio, 2.92; 95% confidence interval, 1.097–7.746; P=0.032) even after multivariate analysis.

CONCLUSION:

Early diagnosis is important to manage MDA. Clinicians should consider MDA among the differential diagnoses in patients with a suspicious clinical presentation even with negative cervical screening tests.
