BACKGROUND AND STUDY AIMS We present a case of invasive micropapillary carcinoma (IMPC) of the colon treated by endoscopic resection following magnifying endoscopy. A 47-year-old woman visited our hospital for follow-up of a positive fecal occult blood test. Colonoscopy revealed a semi-pedunculated reddish polyp, the surface of which showed gentle irregularity, and mild tension in the sigmoid c...

Epithelial borderline ovarian tumors (BOT) are distinctive from benign tumors and carcinoma. They occur in younger women more often than carcinoma, and there is some difficulty making correct diagnosis of BOT. Two subtypes of BOT, serous and mucinous borderline tumor have different characteristics and very different clinical behavior. Serous borderline tumor (SBT) with micropapillary pattern sh...

Since the International Association for the Study of Lung Cancer (IASLC), American Thoracic Society (ATS) and European Respiratory Society (ERS) reported a new lung adenocarcinoma (ADC) classification, several groups have validated its association with prognosis in early stage disease. To our knowledge, there are no studies in advanced disease. We reviewed 313 patients with invasive lung ADC wh...

The distinction between tubular carcinomas (TC) and invasive well-differentiated (grade 1) ductal carcinoma (IDC) is important given treatment and prognostic differences. Studies have described a strong association between flat epithelial atypia (FEA) and TC. The incidence of FEA associated with grade 1 IDC is not well established. The aim of the present study was to assess morphology and intra...

BACKGROUND The purpose of the current study was to evaluate the characteristics of borderline ovarian tumors (BOTs) diagnosed during pregnancy. PATIENTS AND METHODS We conducted a retrospective multicenter study of 40 patients with BOTs diagnosed during pregnancy between 1997 and 2009 at five tertiary universitary departments of Gynecology and Obstetrics and one French cancer center. The medi...

BACKGROUND To evaluate differences in the clinical characteristics and molecular pathology of lung adenocarcinoma subtypes as defined by the new International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society international histological classification. METHODS We retrospectively reviewed 269 patients with initial primary lung adenocarcinoma who had...

The identification of breast ductal carcinoma in situ (DCIS) is a factor that increases 8-10 times the risk of developing invasive ductal breast carcinoma (DCI) later. In this study, we evaluated the immunoexpression of the HER2/neu oncoprotein in the DCIS cases associated with DCI, both in situ and in the invasive components. We also studied the Her2/neu immunoreactivity in the cases of DCI ha...

Pulmonary adenocarcinoma with high-risk pathological factors are known to be associated poor prognosis in early-stage non-small-cell lung cancer (NSCLC). Aumolertinib is a third-generation EGFR-TKI that has efficacy EGFR sensitive and resistant NSCLC. The of aumolertinib as adjuvant therapy resected stage I–III NSCLC remains unknown. Patients underwent completely pathologic micropapillary/solid...
