Risk and prognostic factors for endometrial carcinoma after diagnosis of breast or Lynch ‐associated cancers—A population‐based analysis

Women developing endometrial cancer after tamoxifen treatment for breast cancer are more likely to develop tumours with poorer prognostic features and exhibit poorer survival after adjustment for these prognostic features. Results indicate the importance of longer ‐term monitoring of women treated with tamoxifen for cancer symptoms. Report of prior cancer is a significant indicator of MMR pathogenic variant status, but molecular analysis of endometrial tumors at diagnosis is warranted to detect all patients with Lynch Syndrome. AbstractWe hypothesized that endometrial carcinoma (EC) patients with a prior cancer diagnosis, after accounting for EC arising after tamoxifen ‐treated prior breast carcinoma, are more likely to have an underlying genetic basis. We used information from a population‐based study to compare measured risk factors, tumor characteristics, survival, and known mismatch repair (MMR) pathogenic variant status for EC subgroups according to prior diagnosis of cancer (none, breast cancer tamoxifen‐treated or not, Lynch Syndrome (LS)‐associated cancer). Family history of any cancer was increased for EC cases with prior breast cancer, both tamoxifen treated (P = 0.005) and untreated (P = 0.01). EC cases with prior LS‐associated cancer more often reported family history of LS‐associated cancer (P = 0.04) and breast cancer (P = 0.05). EC patients with a germline pathogenic MMR gene variant were more likely to repo...

This article discusses the characterization with theoretical and experimental basis of Vismodegib, providing a thorough insight knowledge of the drug itself. The energy of the structure was minimized employing a commercial code, and different approaches were used to determine the bond distances and hyperconjugative interactions. The information obtained by theoretical calculation was correlated with experimental data of vibrational spectroscopies: FTIR and Raman. The main vibrational modes were theoretically evaluated and correlated with experimental data.Graphical abstract

In this study, miR-101 expression was markedly downregulated in the OSCC cell lines and tissues. CCK-8, EdU, and colony formation assays showed that miR-101 inhibited the proliferation of OSCC cells. Flow cytometry and caspase-3 activity assays indicated that miR-101 induced OSCC cell apoptosis. Transwell assays demonstrated that this miRNA also repressed OSCC cell migration and invasion. Moreover, tube formation assay showed that miR-101 abated the pro-angiogenesis of OSCC cells. Dual luciferase reporter assay confirmed that miR-101 directly targeted TGF-βR1 in OSCC. Ectopic expression of TGF-βR1 counteracted th...

CONCLUSIONS: T3b, distinguished from minimal ETE, may be related to larger tumor size, higher prevalence of multifocality, LNM, DM, recurrence and worse RFS than no ETE, but it may not affect OS and may not independently predict recurrence in PTC patients.

CONCLUSIONS: The clinical content and evidence explanations in the adult thyroid nodule and differentiated thyroid cancer CPG are widely accepted and applied among ATA survey respondents. Future ATA CPG updates need to be optimized to best meet users' preferences regarding format, frequency and length. PMID: 31830853 [PubMed - as supplied by publisher]

In this study, we investigate, in vitro, whether miRNA-593-5p inhibits NSCLC cell proliferation. To clarify its specific mechanism of inhibition, we used bioinformatics to predict its target genes and identified PLK1. Luciferase reporter assay confirmed the binding of miR-593-5p to the PLK1 3’-UTR in a sequence-specific manner in NSCLC cells. Additionally, we also found through Western blot and quantitative RT-PCR that miR-593-5p down-regulates the expression of PLK1 protein. Finally, PLK1 overexpression was shown to disinhibit NSCLC cell proliferation. Taken together, this evidence suggests that miR-593-5p inhibits ...

ConclusionUreteral neuroendocrine tumors are extremely rare. Neuroendocrine markers (CD56, CgA, Syn) and epithelial markers (CKpan, CK7) are usually helpful. Grimelius special staining and electron microscopy observation can help to make a final diagnosis. Radical surgery together with postoperative adjuvant chemotherapy can improve the survival of patients. Vimentin may play a role in predicting the prognosis.

Authors: Suh DH, Kim M, Lee KH, Eom KY, Kjeldsen MK, Mirza MR, Kim JW Abstract In 2017, 10 topics were selected as major clinical research advances in gynecologic oncology. For cervical cancer, efficacy and safety analysis results of a 9-valent human papillomavirus (HPV) vaccine and long-term impact of reduced dose of quadrivalent vaccine were updated. Brief introduction of KEYNOTE trials of pembrolizumab, a monoclonal antibody that blocks the interaction between programmed death (PD)-1 and its ligands, PD-L1 and PD-L2, followed. Tailored surveillance programs for gynecologic cancer related with Lynch syndrome and ...

Conclusions: The present study is the first to investigate PTEN protein loss in a large set of non-familial breast carcinomas based on their DNA MMR status by IHC. Here, we demonstrated that PTEN strong and homogeneous expression by IHC is able to capture the vast majority of MMR-proficient non-familial breast cancers. Our findings broaden the understanding of the biology underpinning these tumors, suggesting that PTEN is likely play a role in the development of MMR alterations. Given that PTEN-defective breast cancers have the propensity to develop additional somatic alterations in the MMR system, our results suggest that...

We present here two cases of papillary thyroid carcinoma (PTC) in patients affected by Lynch syndrome (LS). The first case is a 47-year-old woman with typical hereditary non-polyposis colorectal cancer (HNPCC) syndrome, reported with endometrial and ovarian carcinoma at age 43, and colon cancer at age 45. The patient underwent total thyroidectomy and central node dissection in 2007, at 47years old, with a histological diagnosis of PTC (T1aN1a). Molecular genetics showed a germ-line mutation of the MLH1 gene, 1858 G>T(E620X), with substitution of glycine with a stop codon at position 620. This mutation has pathogenetic s...
