Case Report and Review of 7 Similar Cases in the Literature: Cutaneous Sarcoidosis as Side Effect of Pembrolizumab Plus Chemotherapy in Stage IV Squamous Cell Carcinoma of Lung

We present an unusual case of cutaneous sarcoidosis in a 63-year-old white female who was diagnosed with stage IV squamous cell lung cancer developed skin manifestations 3 months after started chemo/pembrolizumab. Sarcoidosis was confirmed by skin punch biopsy and resolved after a short course of systemic glucocorticoid while maintained on pembrolizumab with lower frequency. These sarcoid-like lesions associated with the blockage of programmed death receptor-1 have been increasingly described in many different malignancies especially in melanoma. There is a need for further investigation to the characterization of the population prone to this immune-related adverse events.

Papillary thyroid cancer (PTC) is the most common form of differentiated thyroid cancer in the pediatric population and represents the second most common malignancy in adolescent females. Historically, PTC has been classified on the basis of histology, however, accumulating data indicate that molecular subtyping based on somatic oncogenic alterations along with gene expression profiling can better predict clinical behavior and may provide opportunities to incorporate oncogene-specific inhibitory therapy to improve the response to radioactive iodine (RAI). In this issue of the JCI, Y.A. Lee, H. Lee, and colleagues showed th...

BACKGROUND Molecular characterization in pediatric papillary thyroid cancer (PTC), distinct from adult PTC, is important for developing molecularly targeted therapies for progressive radioiodine-refractory (131I-refractory) PTC.METHODS PTC samples from 106 pediatric patients (age range: 4.3–19.8 years; n = 84 girls, n = 22 boys) who were admitted to SNUH (January 1983–March 2020) were available for genomic profiling. Previous transcriptomic data from 125 adult PTC samples were used for comparison.RESULTS We identified genetic drivers in 80 tumors: 31 with fusion oncogenes (RET in 21 patients, ALK in 6 patients,...

Herculean efforts by the Wellcome Sanger Institute, the National Cancer Institute, and the National Human Genome Research Institute to sequence thousands of tumors representing all major cancer types have yielded more than 700 genes that contribute to neoplastic growth when mutated, amplified, or deleted. While some of these genes (now included in the COSMIC Cancer Gene Census) encode proteins previously identified in hypothesis-driven experiments (oncogenic transcription factors, protein kinases, etc.), additional classes of cancer drivers have emerged, perhaps none more surprisingly than RNA-binding proteins (RBPs). Over...

Intratumoral T cells that might otherwise control tumors are often identified in an “exhausted” state, defined by specific epigenetic modifications and upregulation of genes such as CD38, cytotoxic T-lymphocyte–associated protein 4 (CTLA4), and programmed cell death 1 (PD1). Although the term might imply inactivity, there has been little study of this state at the phenotypic level in tumors to understand the extent of their incapacitation. Starting with the observation that T cells move more quickly through mouse tumors the longer they reside there and progress toward exhaustion, we developed a nonstimula...

BACKGROUND Germline mutations in telomerase and other telomere maintenance genes manifest in the premature aging short telomere syndromes. Myelodysplastic syndromes and acute myeloid leukemia (MDS/AML) account for 75% of associated malignancies, but how these cancers overcome the inherited telomere defect is unknown.METHODS We used ultra-deep targeted sequencing to detect somatic reversion mutations in 17 candidate telomere lengthening genes among controls and patients with short telomere syndromes with and without MDS/AML, and we tested the functional significance of these mutations.RESULTS While no controls carried somat...

I was looking through ASCO and ACS with regards to any information pertaining to surveillance imaging recommendations for various cancer types after treatment (surgery, radiotherapy, chemotherapy). I understand that factors such as location and cell type or other markers complicate this and therefore each cancer type is unique. I was able to only find a few guideline articles listed as "current" for maybe 4 or 5 frequently diagnosed cancers. I was curious if any single organization or... Read more

Many recent observations emphasise that hepatocellular carcinoma (HCC) developing on the background of non-alcoholic steatohepatitis (NASH) has distinct features, e.g. less efficacious responses to immunotherapy, but the molecular characteristics of NASH-HCC are not well defined. Pinyol and coworkers analysed transcriptomic and whole exome sequencing data from a large number of NASH, NASH-HCC and non-NASH-HCC samples, alongside analyses of 3 commonly used mouse models of NASH-HCC. Human NASH-HCC has higher rates of (potentially tumour-suppressing) ACVR2A mutations (10%), some typical mutational patterns, a Wnt/TGF- β ...
