TLDR
Recurrent tuberous sclerosis / MTOR pathway gene alterations in LOT supports its consideration as a distinct morphologic, immunohistochemical, and genetic entity, and PIK3CA is another pathway member that may be altered in these tumors.Abstract:
Low‐grade oncocytic tumour (LOT) of the kidney has recently emerged as a potential novel tumour type. Despite similarity to oncocytoma or eosinophilic chromophobe renal cell carcinoma, it shows diffuse keratin 7 immunohistochemistry (IHC) and negative KIT (CD117), which differs from both. We aimed to identify the molecular characteristics of these tumours. Seventeen tumours (one male, 16 female, nine previously published) fitting the original description of this entity (solid eosinophilic cell morphology, often with areas of tumour cells loosely stretched in oedematous stroma, and the above IHC features) were analysed with a next‐generation sequencing panel of 324 cancer‐associated genes from formalin‐fixed, paraffin‐embedded tissue. All tumours harboured at least one alteration in either TSC1 (n = 7, 41%), TSC2 (n = 2, 12%), MTOR (n = 5, 29%) or PIK3CA (n = 4, 24%). Four tumours harboured a second alteration, including two NF2, one each in conjunction with MTOR and TSC2 alterations, one PTEN with TSC1 alteration and one tumour with both MTOR and TSC1 alterations. No other renal cancer‐related or recurring gene alterations were identified. In addition to the previously described IHC findings, 16 of 16 were positive for GATA3. Eleven patients with follow‐up had no metastases or recurrent tumours. Recurrent tuberous sclerosis/MTOR pathway gene alterations in LOT support its consideration as a distinct morphological, immunohistochemical and genetic entity. PIK3CA is another pathway member that may be altered in these tumours. Further study will be necessary to determine whether tumour behaviour or syndromic associations differ from those of oncocytoma and chromophobe carcinoma, warranting different clinical consideration.read more

TL;DR: In this article , the authors investigated the concordance between mTOR pathway mutations and low-grade oncocytic tumor (LOT), which demonstrates overlapping morphologic features with oncocytetoma and chromophobe RCC, but also has a unique immunoprofile (i.e., diffusely positive for KRT7, negative for KIT).
