ABSTRACT
Objective To study the clinicopathological features of breast invasive micropapillary carcino-ma and its treatment and prognosis. Methods Clinical data, radiological examination, histopathology, immuno-histochemistry, therapeutic regimen and follow-up results of 16 cases of invasive micropapillary carcinoma of the breast were collected. The clinicopathological features, immunophenotype, imaging findings, treatment and progno sis were retrospectively analyzed. Results All the 16 cases were female, with mean age of 56.3 years(40 to 89 years). Of the 16 patients, 4 cases were pure invasive micropapillary carcinoma, and 12 cases were mixed invasive mi-cropapillary carcinoma. Among the 12 cases of mixed invasive micropapillary carcinoma, 1 case was mixed with invasive ductal carcinoma, mucinous carcinoma and invasive micropapillary carcinoma, and the remaining 11 cas-es were all non-specific invasive ductal carcinoma with invasive micropapillary carcinoma. Out of the 16 cases, 13 (81.25％) were invasive micropapillary carcinoma with axillary lymph node metastasis, axillary lymph node metas tasis which was more than 4 had 7 cases(43.75％), clinical stage Ⅲ had 8 cases(50％). According to the patho-logical results, 16 cases were treated with individualized comprehensive treatment. Of the 16 patients, 14 were fol-lowed up and 2 were lost. Conclusion Breast infiltrating micropapillary carcinoma is a rare type of breast can-cer, with high rate of axillary lymph nodes metastasis, aggressive lymphatic invasiveness, high malignancy degree and poor prognosis.

ABSTRACT
Syringomatous adenoma of the nipple is a kind of rare breast tumor.It is often misdiagnosed because its clinical and imaging manifestations are similar to other benign and malignant tumors.In this paper,we reviewed clinical data,imaging data,diagnosis and treatment of the tumor diagnosed by histopathology in our hospital,and its clinical features,histopathology,immunohistochemistry,differential diagnosis,treatment and prognosis were discussed in combination with literatures,experience and lessons were summarized to provide a reference for the diagnosis and treatment of this tumor by breast surgeons and pathologists.
ABSTRACT
Objective To investigate the expressions of signal transducer and activator of transcription factor 3 (STAT3),Bcl-2,and matrix metalloproteinase 2 (MMP2) in colorectal adenomas and adenocarcinomas,and the relationship of those factors with the colorectal clinicopathological features and prognosis of intestinal adenocarcinomas,and explore their roles in invasion,metastasis,and prognosis of a colorectal cancer.Methods The samples were selected from Dongyang City People's Hospital from January 2011 to January 2012,including 50 cases of paraffin-coded colorectal mucosas with chronic inflammation,50 cases of paraffincoded colorectal adenomas,and 100 cases of paraffin-coded colorectal adenocarcinomas (35 cases with metastasis and 65 cases without distant metastasis).Envison two method was used to detect the expressions of STAT3,Bcl-2,and MMP2 in each sample.Results The expressions of STAT3,Bcl-2,and MMP2 in colorectal adenomas and adenocarcinomas were significantly higher than those in colorectal mucosas with chronic inflammation (P ＜ 0.05).The expressions of STAT3 and MMP2 in colorectal adenocarcinomas with distant metastasis were significantly higher than that those without distant metastasis (P ＜ 0.05).The expression of BCL-2 had no significant difference between colorectal adenocarcinomas with and without distant metastasis (P ＞ 0.05).Conclusions STAT3,Bcl-2 and MMP2 were associated with occurrence and development of colorectal carcinoma.STAT3 was associated with distant metastasis of colorectal carcinoma and might indicate a poor prognosis.STAT3 might be used as a candidate clinical sign for recurrence,metastasis,and poor survival prognosis of colorectal adenocarcinoma.
