Objectives

Identification of axillary metastases in breast cancer is important for staging disease and planning treatment, but current techniques are associated with a number of adverse events. This report evaluates the diagnostic accuracy of superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance imaging (MRI) techniques for identification of axillary metastases in breast cancer patients.

Methods

We performed a meta-analysis of previous studies that compared SPIO enhanced MRI with histological diagnosis after surgery or biopsy. We searched PubMed, Ovid, Springer Link, and Cochrane library to identify studies reporting data for SPIO enhanced MRI for detection of axillary lymph node metastases in breast cancer until December 2013. The following keywords were used: “magnetic resonance imaging AND axilla” and “superparamagnetic iron oxide AND axilla”. Eligible studies were those that compared SPIO enhanced MRI with histological diagnosis. Sensitivity and specificity were calculated for every study; summary receiver operating characteristic and subgroup analyses were done. Study quality and heterogeneity were also assessed.

Results

There were 7 publications that met the criteria for inclusion in our meta-analysis. SROC curve analysis for per patient data showed an overall sensitivity of 0.83 (95% Confidence interval (CI): 0.75–0.89) and overall specificity of 0.97 (95% CI: 0.94–0.98). Overall weighted area under the curve was 0.9563.

Conclusions

SPIO enhanced MRI showed a trend toward high diagnostic accuracy in detection of lymph node metastases for breast cancer. So, when the breast cancer patients has axillary metastases histologically, SPIO enhanced MRI may be effective diagnostic imaging modality for axillary metastases.

Abstract Objectives

Breast conserving surgery (BCS) for early breast cancer is now an accepted treatment, but there are controversies about its comparability with mastectomy. Thus, we investigated the survival outcomes who underwent BCS and modified radical mastectomy (MRM).

Methods

In this retrospective review, we analyzed the survival outcomes of 618 patients with early breast cancer who underwent two different surgery from January 2002 to December 2009. Postoperative pathologic difference, disease free survival period, overall survival period, recurrence pattern, recurrent rate and site were compared. In addition, preoperative patients data are also collected.

Results

Disease free survival period of MRM and BCS was 108.46 months and 80.82 months, respectively (P< 0.01). However, there was no significant correlation between overall survival period and operative methods (P= 0.67). In addition, recurrence pattern (P= 0.21), recurrent rate (P= 0.36) and site (P= 0.45, P= 0.09) were not associated with operative method.

Conclusions

In this study, we can suggest that early breast cancer patients could improve their disease free survival if they underwent MRM. So, when we operate high risk breast cancer patients, MRM could be considered for their disease free life. Further studies may be required to establish appropriate strategy of surgery for early breast cancer.

Abstract

Peritoneal and gastrointestinal metastasis from breast cancer is very rare. We report here a rare case of metastatic peritoneal and gastric cancer from breast lobular carcinoma after modified radical mastectomy. A 65-year old woman presented with anorexia, nausea, vomiting and dyspepsia for several weeks at 44 months after surgery. Radiologic study showed peritoneal metastasis, and surgical histopathology reported peritoneal and omental metastatic carcinoma. Esophagogastroduodenoscopic (EGD) biopsy also confirmed metastatic carcinoma originated from breast primary.
