  • Machine Protection Experience from Beam Tests with Crab Cavity Prototypes in the CERN SPS

    • Crab cavities (CCs) constitute a key component of the High Luminosity LHC (HL-LHC) project. In case of a failure, they can induce significant transverse beam offsets within tens of microseconds, necessitating a fast removal of the circulating beam to avoid damage to accelerator components due to losses from the displaced beam halo. In preparation for the final design to be employed in the LHC, a series of tests were conducted on prototype crab cavities installed in the Super Proton Synchrotron (SPS) at CERN. This paper summarizes the machine protection requirements and observations during the first tests of crab cavities with proton beams in the SPS. In addition, the machine protection implications for future SPS tests and for the use of such equipment in the HL-LHC are discussed.

  • Best Practices Recommendations for Diagnostic Immunohistochemistry in Lung Cancer
  • 2019
  • Ingår i: Journal of Thoracic Oncology. - : Elsevier BV. - 1556-0864 .- 1556-1380. ; 14:3, s. 377-407

    • Since the 2015 WHO classification was introduced into clinical practice, immunohistochemistry (IHC) has figured prominently in lung cancer diagnosis. In addition to distinction of small cell versus non-small cell carcinoma, patients' treatment of choice is directly linked to histologic subtypes of non-small cell carcinoma, which pertains to IHC results, particularly for poorly differentiated tumors. The use of IHC has improved diagnostic accuracy in the classification of lung carcinoma, but the interpretation of IHC results remains challenging in some instances. Also, pathologists must be aware of many interpretation pitfalls, and the use of IHC should be efficient to spare the tissue for molecular testing. The International Association for the Study of Lung Cancer Pathology Committee received questions on practical application and interpretation of IHC in lung cancer diagnosis. After discussions in several International Association for the Study of Lung Cancer Pathology Committee meetings, the issues and caveats were summarized in terms of 11 key questions covering common and important diagnostic situations in a daily clinical practice with some relevant challenging queries. The questions cover topics such as the best IHC markers for distinguishing NSCLC subtypes, differences in thyroid transcription factor 1 clones, and the utility of IHC in diagnosing uncommon subtypes of lung cancer and distinguishing primary from metastatic tumors. This article provides answers and explanations for the key questions about the use of IHC in diagnosis of lung carcinoma, representing viewpoints of experts in thoracic pathology that should assist the community in the appropriate use of IHC in diagnostic pathology.

  • Biochemical Testing in Patients with Neuroendocrine Tumors
  • 2015
  • Ingår i: Neuroendocrine Tumors. - : Krager. - 9783318027730 - 9783318027723 ; 44, s. 24-39
  • Bokkapitel (refereegranskat)abstract
    • Neuroendocrine tumors are usually slow-growing tumors. Many of these are capable of secreting peptide hormones or biogenic amines that may lead to endocrine syndromes. Nonfunctioning tumors can either secrete no hormones at all, or secrete hormones not giving rise to endocrine symptoms, such as chromogranin A, chromogranin B or pancreatic polypeptide. Chromogranin A is produced by the majority of endocrine tumors, both functioning and nonfunctioning, and is the best available marker for diagnosis, follow-up and treatment monitoring of patients with differentiated neuroendocrine tumors. Examples of endocrine syndromes are classical carcinoid syndrome caused by serotonin (measured in the urine as its metabolite 5-HIAA), insulinoma syndrome caused by insulin or proinsulin, Zollinger-Ellison syndrome resulting from gastrin secretion, glucagonoma syndrome caused by glucagon, WDHA syndrome caused by vasoactive intestinal peptide, or Cushing's syndrome resulting from ectopic production of adrenocorticotropic hormone or corticotropin-releasing hormone. In case there is uncertainty about the diagnosis, specific tests can be applied, such as the secretin test for diagnosis of gastrinomas and the 72-hour fast for diagnosis of an insulinoma. In patients with suspicion of an inherited syndrome, such as multiple endocrine neoplasia (MEN) 1 and MEN2 syndromes, genetic testing is indicated.
