approved for people with advanced kidney cancer. Researchers want to see if it also helps
people with two other types of kidney cancer.

- Birt-Hogg-Dube (BHD) is a hereditary cancer syndrome with clinical manifestations
including cutaneous fibrofolliculomas, lung cysts/pneumothorax, and renal cell carcinoma
(RCC). RCC occurs in approximately 30% of patients with BHD. It presents at an early age
of onset and is commonly bilateral and multifocal.
- Tumors associated with BHD can have variable histology, however approximately 85% of
these tumors have a chromophobe component (either alone or part of a hybrid tumor mixed
with elements of oncocytoma).
- The current management includes surgical resection with partial nephrectomy when tumors
reach 3 cm. While significant morbidity can be associated with repeat, partial
nephrectomy with this approach, most patients can maintain renal function and do not
develop systemic disease. There are no proven systemic therapy options for BHD to date.
- Germline mutations in the gene Folliculin (FLCN) are the genetic hallmark of BHD and can
be found in greater than 90% of patients. FLCN is believed to function like a classic
tumor suppressor gene with a second hit in the wild type allele (somatic mutation or
loss of heterozygosity) occurring in the majority of renal tumors.
- BHD is in the family of harmatomaous disorders similar to TSC and Cowden Syndrome, and
studies have found activation of the PI3K/mTOR pathway in BHD renal tumors. FLCN is
believed be part of a complex that interacts with AMPK and is involved with regulation
of mTOR activity. In vitro and in vivo models of FLCN loss demonstrate activation of
both mTORC1 and mTORC2.
- Preclinical data from conditional FLCN knockout mice demonstrate that treatment with
sirolimus can reverse renal manifestations.
- We hypothesize that mTOR inhibition with everolimus treatment will be clinically active
in BHD associated RCC.

BHD-associated renal tumors.
