Favourable molecular characteristics have previously been described in screen-detected tumours including higher expression of ER and PR and less frequent expression of HER2 and Ki-67 (Crosier et al, 1999; Joensuu et al, 2004).
For instance, serous carcinomas show WT1, Mesothelin, oestrogen receptor and CA125 expression in >75%, while the mucinous subtype displays frequent expression of Matriptase, and endometrioid carcinomas express high rates of estrogen and progesterone receptor and CA125 (Köbel et al, 2008).
Luminal B subtype tended to have high nuclear grade and more frequent expression of EGFR and NF-κB.
Luminal B tumors tend to have high nuclear grade and more frequent expression of EGFR and NF-κB.
Indeed, immunotherapy plays a major role in melanoma [ 20] with extraordinary responses in patients treated with immune checkpoint inhibitors and we have previously demonstrated the spontaneous immunogenicity of cutaneous melanoma by the frequent expression on CT7 and CT10 and spontaneous immune responses to CT7 in these patients.
Comparison with 5 eAML cases including 2 malignant tumors showed similar morphology and immune reactivity except for more frequent expression of HMB45 and lack of PAX8 positivity.
Despite the frequent expression of EPO and EPOR in RCC, approximately 35% of RCC patients develop anaemia, whilst only 1-51-5%polycythaemianeoplastic polycythaemia [ 37, 47, 62, 80- 83].
Frequent expression of CXCR4 and its ability to promote liver metastasis in PAC may explain the well-known, but poorly understood, predilection for PAC to metastasize to liver and why adjuvant chemotherapy provides only modest protection against liver recurrence.
In this study, we analysed the expression of CT7 and CT10 in 54 MM samples and detected a frequent expression of CT7 in primaries and corresponding metastases (55%) as well as of CT10 (30%).
Subsequent immunohistochemical analysis in a series of 153 unselected cases of breast cancer confirmed the more frequent expression of MAGE-A and NY-ESO-1 protein in ER-negative tumors, and similar findings were also observed by analyzing 19 cases of ER, PR and HER2 triple-negative breast cancer.
