BACKGROUND
Micropapillary carcinoma (MPC) is known to have a worse prognosis than the other subtypes of breast cancer. Occasionally, MPC is observed in association with invasive ductal carcinoma not otherwise specified (IDC NOS), as well as mucinous carcinoma.
METHODS
We examined the immunohistochemical expression of an estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) in 127 cases of surgically resected MPC or IDC NOS with MPC. Further, we classified these cases based on their immunohistochemical profile.
RESULTS
Among the IDC NOS with MPC cases, 47 were luminal A (62.7%), 10 were luminal B (13.3%), and 9 were HER2 (12.0%). The MPC cases included 4 luminal A (50.0%), 2 luminal B (25.0%) and 1 HER2 (12.5%) subtypes. Of the mucinous carcinomas with MPC, 4 were grouped as luminal A (57.1%), 1 as luminal B (14.3%), and 2 as HER2 (28.6%) subtypes. However, among the mucinous carcinomas, 33 were categorized as luminal A (89.2%), 3 as luminal B (8.1%), and 1 as HER2 (2.7%) subtype, indicating a low incidence of HER2 subtype as compared to the other subtypes.
CONCLUSIONS
The luminal B and HER2 subtypes were prevalent in carcinomas with MPC. This result explains the poor prognosis of breast carcinomas with an MPC pattern.

BACKGROUND
Cystic renal cell carcinoma has been reported to have a good prognosis. However, previous studies included cases of multilocular cystic renal cell carcinoma, which has an excellent prognosis, and renal cell carcinoma with cystic necrosis, which has an adverse prognosis. Therefore, we analyzed the prognostic influence of cystic change in clear cell renal cell carcinoma after excluding those morphological features.
METHODS
We identified 225 patients with clear cell renal cell carcinoma who underwent nephrectomy between 2001 and 2003. The clinicopathologic features were compared with clinical outcomes.
RESULTS
Cystic change in clear cell renal cell carcinoma (n = 66) was significantly associated with younger patient age (< 55), smaller tumor size (< or = 4 cm), lower pT stage (pT1, T2), M0 stage at initial diagnosis, lower tumor, node, and metastasis stage (I, II), and lower nuclear grade (1, 2). Patients with cystic change in clear cell renal cell carcinoma had significantly longer cancer-specific (p = 0.015) and progression-free survival (p = 0.004) than those without cystic change, by univariate analysis. Multivariate analysis revealed that cystic change significantly decreased the risk of cancer progression (risk ratio, 0.27; 95% confidence interval, 0.11 to 0.69).
CONCLUSIONS
In patients with clear cell renal cell carcinoma, cystic change is a good independent predictor for survival.

Abstract PDF: BACKGROUND
Chromophobe renal cell carcinoma is a category of renal cell carcinoma composed of histologically characteristic tumor cells. E-cadherin is an intercellular adhesion protein that has been correlated with tumor aggressiveness in many carcinomas, including clear cell renal cell carcinoma. However, the significance of an E-cadherin expression in chromophobe renal cell carcinoma is not known.
METHODS
We evaluated the E-cadherin expression status of 65 chromophobe renal cell carcinomas by performing immunohistochemical staining with the tissue microarray method. The percentage of positively stained tumor cells was evaluated and this was then classified into two categories: a low expression where 0 to 25% of the cells are positive, and a high expression where more than 25% of the cells are positive.
RESULTS
Among 65 cases, 11 cases (17%) showed a low expression, and 54 cases (83.0%) showed a high expression. The tumors with low expression were more likely to have a higher stage but this was not significant (p=0.056). On the survival analysis, a low E-cadherin expression was significantly associated with poor cancer-specific survival (p=0.005) and progression-free survival (p=0.003).
CONCLUSIONS
The E-cadherin expression is a good prognostic marker for survival in patients with chromophobe renal cell carcinoma.
