Bilateral metastases to the extraocular muscles from small cell lung carcinoma

We report a case of bilateral extraocular muscle metastases from a small cell lung carcinoma and provide a review of the relevant literature. A 56-year-old smoker presented with proptosis, motility changes, and a relative afferent pupillary defect of the left eye, with a previous history of a small cell lung carcinoma. An orbital computerized tomography scan revealed a mass restricted to the left medial rectus. An incisional biopsy confirmed metastasis. Visual acuity of the left eye decreased rapidly, and right globe proptosis became evident. Orbital magnetic resonance imaging at two months follow-up showed marked left orbital mass enlargement and a new right lateral rectus mass. The patient was maintained on palliative care and died from metastatic disease-related complications.RESUMO As met ástases orbitárias bilaterais restritas aos mús­culos extraoculares são extremamente raras. Os autores apresentam um caso de metástases bilaterais, localizadas aos musculares extraoculares com base num carcinoma de pequenas células do pulmão e revisão da literatura relevante. Um homem, fuma dor, de 56 anos recorreu ao serviço de urgência por proptose, alterações de motilidade ocular extrínseca e um defeito pupilar aferente relativo do olho esquerdo, com história pessoal de carcinoma de pequenas células do pulmão. A tomografia computadorizada orbitária revelou uma mass...

AbstractPurpose of ReviewLiver transplantation (LT) has been utilized in the last two decades for the treatment of selected patients with hepatocellular carcinoma (HCC). Currently, in most jurisdictions worldwide, only tumor size and number determine transplant candidacy, which may not sufficiently predict tumor behavior. Both tumor downstaging and expanding transplant criteria play an important role in expanding access to LT for HCC patients.Recent FindingsNew downstaging protocols are emerging that incorporate response to locoregional therapies (LRT) among those that initially present beyond the accepted Milan criteria. ...

Conclusion: Our findings, along with other reports, suggest that MKIs is an effective neoadjuvant therapy and should be considered as a therapeutic strategy for unresectable grossly locally invasive thyroid carcinomas.

Dysphagia represents one of the most serious adverse events after curative-intent treatments with a tremendous impact on quality of life in patients with head and neck cancers. Novel surgical and radiation therapy techniques have been developed to better preserve swallowing function, while not negatively influencing local control and/or overall survival. This review focuses on the current literature of swallowing outcomes after curative treatment strategies. Available results from recent studies relevant to this topic are presented, demonstrating the potential role of new treatment modalities for early- and intermediate-st...

Conclusions: The 7th edition of the TNM classification for esophageal carcinoma is poorly recognized and understood in central and southern China, which might contribute to the relatively low rates of appropriate perioperative procedures applied for esophageal cancer patients.

In this study, we analyzed two datasets (GSE 94508 and GSE 97332) to examine differentially expressed circRNAs markedly related to HCC pathogenesis. Using Limma package in R and WGCNA analysis, hsa_circ_0000517 was significantly up-regulated in HCC (adjusted P

Epstein-Barr virus (EBV) establishes lifelong latent infection in humans and is associated with several lymphoid and epithelial cancers. In nasopharyngeal carcinoma (NPC), EBV expresses few viral proteins but elevated levels of Bam-HI A rightward transcripts (BARTs) RNA, which includes viral microRNAs and long non-coding RNAs (lncRNAs). BART lncRNAs localize within the nucleus of EBV-infected cells and knockdown of BART lncRNAs significantly affects the expression of genes associated with cell adhesion, oxidoreductase activity, inflammation, and immunity. Notably, downregulation of IKAROS family zinc finger 3 (IKZF3/Aiolos...

ConclusionsThe relevance of SPARC expression in pancreato-biliary carcinomas though may still be important for therapeutic decision making, it is not responsible for peritumoral stromal desmoplasia in these tumors and it does not have any significant prognostic implication.

Basosquamous carcinomas (BSCs), which comprise 1.2 –2.7% of skin carcinomas, are aggressive skin tumors that feature histopathologic characteristics of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BSC origin and genetic etiology remain controversial. Chiang and colleagues reported underlying PTCH and SMO mutations in BSCs, su ggesting that Hedgehog signaling drives BSC similar to BCC. Principal component analysis indicated that BSC has greater genetic similarity to BCC than to SCC, supporting the concept that BSCs are derived from BCCs.
