  • Significance, diagnosis and treatment of lateral lymph nodes in rectal cancer : A systematic review
  • 2019

    • Introduction: Patients with low rectal cancer are at risk for lateral lymph node metastasis (LLNM). Neoadjuvant chemoradiotherapy (CRT) is used to eradicate LLNM in the West, whereas in Japan the addition of lateral lymph node dissection (LLND) to total mesorectal excision (TME) is performed. A systematic review was conducted to assess incidence, location, risk factors and diagnosis of LLNM and lateral lymph node (LLN) treatment outcomes. Method: The Medline, Embase and Cochrane databases were searched for English-language articles pertaining to LLNs in rectal cancer. Results: 242 studies were identified and 15 prospective studies selected for qualitative analysis. LLNM was detected in 7–40% of patients who underwent LLND, and lower incidence occurred in patients without preoperative suspicion of LLNM. LLNs located along the middle rectal artery were most common. LLNM was associated with female sex, advanced T stage and positive mesorectal nodes. LLN short-axis diameter of ≥10 mm on preoperative imaging appeared to predict LLNM after neoadjuvant CRT. The addition of LLND to TME seemed to decrease LR and improve survival rates, with comparable results seen for CRT. LLND appeared to be associated with longer operation time, greater blood loss and increased risk of sexual and urinary dysfunction. Conclusion: LLND could be advantageous for patients with suspected LLNM, but associated morbidities need to be considered. Further studies are needed to improve preoperative identification of LLNs and to determine how to manage persistent enlarged LLNs after CRT. Furthermore, the applicability of LLND in a Western population needs to be investigated.

  • Whole-Exome Sequencing Identifies Rare and Low-Frequency Coding Variants Associated with LDL Cholesterol.
  • 2014
  • Ingår i: American Journal of Human Genetics. - : Elsevier BV. - 0002-9297. ; 94:2, s. 233-245
  • Tidskriftsartikel (refereegranskat)abstract
    • Elevated low-density lipoprotein cholesterol (LDL-C) is a treatable, heritable risk factor for cardiovascular disease. Genome-wide association studies (GWASs) have identified 157 variants associated with lipid levels but are not well suited to assess the impact of rare and low-frequency variants. To determine whether rare or low-frequency coding variants are associated with LDL-C, we exome sequenced 2,005 individuals, including 554 individuals selected for extreme LDL-C (>98(th) or <2(nd) percentile). Follow-up analyses included sequencing of 1,302 additional individuals and genotype-based analysis of 52,221 individuals. We observed significant evidence of association between LDL-C and the burden of rare or low-frequency variants in PNPLA5, encoding a phospholipase-domain-containing protein, and both known and previously unidentified variants in PCSK9, LDLR and APOB, three known lipid-related genes. The effect sizes for the burden of rare variants for each associated gene were substantially higher than those observed for individual SNPs identified from GWASs. We replicated the PNPLA5 signal in an independent large-scale sequencing study of 2,084 individuals. In conclusion, this large whole-exome-sequencing study for LDL-C identified a gene not known to be implicated in LDL-C and provides unique insight into the design and analysis of similar experiments.

  • Controversies in Diagnosis of Pulmonary Embolism
  • 2011
  • Ingår i: Clinical and Applied Thrombosis/Hemostasis. - : SAGE Publications. - 1938-2723 .- 1076-0296. ; 17:2, s. 140-149
  • Tidskriftsartikel (refereegranskat)abstract
    • The approach to the diagnosis of acute pulmonary embolism (PE) is under constant revision with advances in technology, noninvasive approaches, and increasing awareness of the risks of ionizing radiation. Optimal approaches in some categories of patients are controversial. Data are insufficient for evidence-based recommendations. Therefore, this survey of investigators in the field was undertaken. Even among experts there were marked differences of opinion regarding the approach to the diagnosis of acute PE. Although CT pulmonary angiography was usually the imaging test of choice, the respondents were keenly aware of the dangers of ionizing radiation. In view of advances in scintigraphic diagnosis since the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) trial, ventilation/perfusion (V/Q) lung scans or perfusion scans alone and single photon emission computed tomography (SPECT) V/Q lung scans are often recommended. The choice depends on the patient's age, gender, and complexity of the findings on the plain chest radiograph.
