Higher prevalence is associated with a family history of BC and/or OC, early onset, male BC or multiple tumours such as bilateral breast cancer (BBC) or BC and OC in the same patient [ 5].
However, in patients with inherited conditions resulting in multiple tumours (such as those with Gorlin's syndrome), repeated surgical interventions may become untenable, and radiation therapy may be contraindicated because of the high risk of patients developing further BCCs (Leger et al, 2011).
Differential diagnosis is multiple metastases from hypovascular tumours, such as gallbladder, lung and ovarian cancer [40], and multifocal involvement with AIP (Fig. 8) [41].
These risks, together with the very high SIRs from multiple tumours in the parental probands, such as 7.25 from three tumours and 14.93 from four tumours provide strong evidence for heritable effects in skin SCC.
Strokes, malignant tumours such as gliomas, and multiple sclerosis also may affect this region.
In the other tumours, such as brain neoplasia or multiple myeloma, the utility is still questioned and there does not seem to be much improvement in diagnostic accuracy compared with other PET tracers, such as 11C-methionine for brain tumours and 18F-FDG for multiple myeloma [15].
As such, targeting phosphatases may prove more effective in tumours, such as GBM, with co-activation of multiple RTK pathways, which respond poorly to kinase inhibitor monotherapy.
In contrast, tumours such as breast cancer and melanoma typically metastasize to multiple organ sites 61.
Mutations and the down-regulation of Hippo pathway components, such as Mst1/2 and Lats1/2, have been observed in multiple tumours.
miR-483-5p has been associated with several pathological conditions, including tumours such as adrenocortical and ovarian serous carcinoma [ 21, 22], cartilage-associated pathologies such as multiple osteochondroma [ 23] and osteoarthritic chondrocytes [ 24].
Renal oncocytosis (multiple oncocytic lesions) is a recently established disease entity defined as diffuse replacement of the renal parenchyma by numerous oncocytic tumours, such as hybrid tumours, chromophobe RCCs, renal oncocytomas, and oncocytic renal parenchyma [25].
