TL;DR: In the current study, high doses of tamoxifen in combination with sulindac were used to treat severe desmoid tumors to avoid surgery.
Abstract: BACKGROUND
Desmoid tumors are mesenchymal nonmetastasizing neoplasms. Although rare in the general population, they are a common extracolonic manifestation of familial adenomatous polyposis (FAP). Because of high tumor recurrence rates, surgery has been less than satisfactory in the treatment of desmoid tumors. In the current study, high doses of tamoxifen in combination with sulindac were used to treat severe desmoid tumors to avoid surgery.
METHODS
Since 1992, 25 patients at Heinrich Heine University (Dusseldorf, Germany) were treated with a combination of tamoxifen and sulindac. In the current study, 17 patients with FAP-associated and 8 patients with sporadic desmoid tumors received 120 mg of tamoxifen and 300 mg of sulindac daily. Every 6 months, the protracted course of desmoid growth was measured by computed tomography and/or magnetic resonance imaging scans. Tumor responses were characterized as progressive disease, stable disease (SD), partial regression (PR), and complete regression (CR).
RESULTS
Of the group of patients who received tamoxifen and sulindac as a primary treatment, all three patients with sporadic desmoid tumors demonstrated cessation of growth, and 10 of the 13 patients with FAP-associated tumors achieved either a PR or CR. In the sporadic desmoid tumor group, eight of nine patients developed tumor recurrences after undergoingsurgery at other institutions. Of these, two patients had SD and two patients had a PR to CR.
CONCLUSIONS
The patients with desmoid tumors who were managed conservatively with high-dose tamoxifen and sulindac had the best outcome. Desmoid tumor recurrence after surgery was high and in the FAP-associated tumor group, therapy with tamoxifen and sulindac was found to be less successful. Based on this experience, the authors recommended high-dose tamoxifen and sulindac as the primary treatment for patients with FAP-associated desmoid tumors. However, to our knowledge, the best approach after surgical intervention for patients with sporadic desmoid tumors remains to be determined. Cancer 2004. © 2003 American Cancer Society.

TL;DR: Using PAR-CLIP, global RNA targets for all human FET proteins and two ALS-causing human FUS mutants were defined and FET members showed similar binding profiles, whereas F US mutants showed a drastically altered binding pattern, consistent with changes in subcellular localization.
Abstract: FUS, EWSR1 and TAF15, constituting the FET protein family, are abundant, highly conserved RNA-binding proteins with important roles in oncogenesis and neuronal disease, yet their RNA targets and recognition elements are unknown. Using PAR-CLIP, we defined global RNA targets for all human FET proteins and two ALS-causing human FUS mutants. FET members showed similar binding profiles, whereas FUS mutants showed a drastically altered binding pattern, consistent with changes in subcellular localization.

TL;DR: The well-characterized hereditary basis and the unique functional nature of these neuroendocrine tumors provide a useful framework that offers advantages for establishing the pathways of tumorigenesis and malignancy.
Abstract: Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors that are usually benign, but which may also present as or develop into a malignancy. Predicting such behavior is notoriously difficult and there are currently no curative treatments for malignant tumors. This report follows from a workshop at the Banbury Conference Center, Cold Spring Harbor, New York, on the 16th-18th November 2003, held to review the state of science and to facilitate future progress in the diagnosis and treatment of malignant pheochromocytoma. The rarity of the tumor and the resulting fragmented nature of studies, typically involving small numbers of patients, represent limiting factors to the development of effective treatments and diagnostic or prognostic markers for malignant disease. Such development is being facilitated by the availability of new genomics-based tools, but for such approaches to succeed ultimately requires comprehensive clinical studies involving large numbers of patients, stringently collected clinical data and tumor samples, and interdisciplinary collaborations among multiple specialist centers. Nevertheless, the well-characterized hereditary basis and the unique functional nature of these neuroendocrine tumors provide a useful framework that offers advantages for establishing the pathways of tumorigenesis and malignancy. Such findings may have relevance for understanding the basis of other more common malignancies where similar frameworks are not available. As the relevant pathways leading to pheochromocytoma are established it should be possible to take advantage of the new generation of drugs being developed to target specific pathways in other malignancies. Again the success of this will require well-designed and coordinated multi-center studies.

TL;DR: Trans-ethnic analyses of exome array data identify new risk loci for type 2 diabetes and fine-mapping analyses using genome-wide association data show that the index coding variants represent the likely causal variants at only a subset of these loci.
Abstract: We aggregated coding variant data for 81,412 type 2 diabetes cases and 370,832 controls of diverse ancestry, identifying 40 coding variant association signals (P < 2.2 × 10−7); of these, 16 map outside known risk-associated loci. We make two important observations. First, only five of these signals are driven by low-frequency variants: even for these, effect sizes are modest (odds ratio ≤1.29). Second, when we used large-scale genome-wide association data to fine-map the associated variants in their regional context, accounting for the global enrichment of complex trait associations in coding sequence, compelling evidence for coding variant causality was obtained for only 16 signals. At 13 others, the associated coding variants clearly represent ‘false leads’ with potential to generate erroneous mechanistic inference. Coding variant associations offer a direct route to biological insight for complex diseases and identification of validated therapeutic targets; however, appropriate mechanistic inference requires careful specification of their causal contribution to disease predisposition.
