  • Variations in clinicopathologic characteristics of thyroid cancer among racial ethnic groups: analysis of a large public city hospital and the SEER database.

    American journal of surgery 2013 Nov

    Authors: Moo-Young TA,
    Clinicopathologic variables influence the treatment and prognosis of patients with thyroid cancer.
    A retrospective analysis of public hospital thyroid cancer database and the Surveillance, Epidemiology and End Results 17 database was conducted. Demographic, clinical, and pathologic data were compared across ethnic groups.
    Within the public hospital database, Hispanics versus non-Hispanic whites were younger and had more lymph node involvement (34% vs 17%, P < .001). Median tumor size was not statistically different across ethnic groups. Similar findings were demonstrated within the Surveillance, Epidemiology and End Results database. African Americans aged <45 years had the largest tumors but were least likely to have lymph node involvement. Asians had the most stage IV disease despite having no differences in tumor size, lymph node involvement, and capsular invasion.
    There is considerable variability in the clinical presentation of thyroid cancer across ethnic groups. Such disparities persist within an equal-access health care system. These findings suggest that factors beyond socioeconomics may contribute to such differences.

  • Trends in thyroid surgery in Illinois.

    Surgery 2013 Nov

    Authors: Cherenfant J,
    Endocrine surgery is an evolving subspecialty in general surgery. To determine whether this subspecialty is having an effect on practice patterns of thyroid surgery, we reviewed all thyroidectomies performed in Illinois over an 11-year period.
    The Illinois COMPdata database from the Illinois Hospital Association was used to retrieve all the thyroid operations performed in the state of Illinois from 1999 to 2009. Univariate and multivariate logistic regression analyses were performed to assess the effects of surgeon and hospital type on practice patterns of thyroidectomies.
    In the early period (1999-2004), 5,824 operations were identified compared with 8,454 in the late period (2005-2009; P < .001). Total thyroidectomy represented 2,679 (46%) of the thyroid operations done in the early period compared with 4,976 (59%) in the late period (P < .001). Sixty-two percent of all the thyroid operations were done at community hospitals in the early period compared with 56% in the late period. Endocrine surgeons (ES) performed the greatest rate of thyroidectomies, 0.7 and 0.6/10(5) population, in both early and late periods, respectively.
    In Illinois, the volume of thyroid operations has increased significantly over the past 10 years with a shift toward total thyroidectomy. Although most thyroidectomies are still performed in community hospitals, this percentage has decreased. ES perform a minority of thyroid operations, but they have the greatest volume of thyroidectomies per surgeon. These findings may represent broader trends in thyroid surgery throughout the United States.

  • Sporadic and familial medullary thyroid carcinoma: state of the art.

    The Surgical clinics of North America 2009 Oct

    Authors: Moo-Young TA,
    Medullary thyroid cancer (MTC) accounts for 5% to 10% of all thyroid cancers. The high frequency of familial cases mandates screening and genetic testing. The aggressiveness and age of onset of familial MTC differs depending on the specific genetic mutation, and this should determine the timing and extent of surgery. Sporadic MTC can present at any age, and it is usually associated with a palpable mass and the presence of nodal metastases. Surgery is standard treatment for any patient presenting with resectable MTC. Further studies are needed to investigate the role of radiation therapy in the palliation and local control of postresection and advanced-stage MTC. New systemic therapies for metastatic disease are being investigated. Targeted molecular therapies, based on knowledge of the pathways affected by RET mutations, are being tested in multiple clinical trials.

  • Common bile duct injury following laparoscopic cholecystectomy in the setting of sinistroposition of the galladder and biliary confluence: a case report.

    Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract 2010 Jan

    Authors: Moo-Young TA,
    A bile duct injury occurred to a 64-year-old female with highly aberrant bile ducts due to sinistroposition. Methods of potential injury avoidance are discussed.
    A patient underwent elective laparoscopic cholecystectomy for symptomatic cholelithiasis. A left-sided gallbladder was diagnosed intraoperatively. Three days later, the patient presented with jaundice and rising liver function tests. The patient was referred to our institution for suspected bile duct injury. Endoscopic retrograde cholangiopancreatography showed complete occlusion of the common bile duct. A percutaneous transhepatic tube was placed in the bile ducts for decompression. During later operative exploration, a left-sided common hepatic duct was discovered. Review of preoperative imaging confirmed that the right hepatic duct crossed superior to the umbilical portion of the left portal vein and that segment 4 ducts drained into the right anterior sectional bile duct.
    This case describes an extremely rare anomaly associated with an injury to the common bile duct during laparoscopic cholecystectomy. Knowledge of the complex and unusual alterations in biliary anatomy, which may accompany sinistroposition of the gallbladder, should aid in avoidance of such injuries in the future.

  • Tumor-derived TGF-beta mediates conversion of CD4+Foxp3+ regulatory T cells in a murine model of pancreas cancer.

    Journal of immunotherapy (Hagerstown, Md. : 1997) 2009 Jan

    Authors: Moo-Young TA,
    CD4+25+Foxp3+ regulatory T cells (Treg) play a critical role in the induction of tolerance to tumor-associated antigens and suppression of antitumor immunity. How Treg are induced in cancer is poorly understood. We reported previously that Treg are significantly elevated in the peripheral blood of patients with pancreas cancer and that in a murine pancreas cancer model induction of Treg seems to be transforming growth factor (TGF)-beta dependent. Here we provide additional evidence that Treg are increased locally within the tumor microenvironment by a mechanism that seems dependent on TGF-beta receptor expression and the presence of tumor derived TGF-beta. The murine pancreas cancer cell line Pan02 produces high levels of TGF-beta both in vitro and in vivo. In contrast, the esophageal murine cancer cell line, Eso2, does not. Immunohistochemical staining of Foxp3 in explanted tumors shows an identifiable population of Treg in the Pan02 (TGF-beta positive) tumors but not Eso2 (TGF-beta negative). Naive CD4+25-Foxp3- T cells, when adoptively transferred into Rag-/- mice, are converted into Foxp3+ Treg in the presence of Pan02 but not Eso2 tumors. Induction of Treg in Pan02 mice is blocked by systemic injection of an anti-TGF-beta antibody. If Rag-/- mice are instead reconstituted with naive CD4+25- T cells expressing a mutated TGF-beta receptor, induction of Foxp3+ Treg in Pan02 bearing mice is blocked. Collectively, these observations further support the role of TGF-beta in the induction of Treg in pancreas adenocarcinoma.

  • Increased prevalence of regulatory T cells (Treg) is induced by pancreas adenocarcinoma.

    Journal of immunotherapy (Hagerstown, Md. : 1997)

    Authors: Liyanage UK,
    We reported earlier that patients with breast or pancreas cancer have an increased prevalence of regulatory T cells (Treg) in the blood and tumor draining lymph nodes (TDLNs) compared with healthy individuals. In the current study, we tested the hypothesis that tumor cells promote the prevalence of Treg. The transforming growth factor-beta (TGF-beta) secreting murine pancreas adenocarcinoma, Pan02 cell line was injected into syngeneic C57BL/6 mice and the prevalence of Treg in the TDLNs and tumor spleen was measured weekly. Compared with control mice, the prevalence of CD25+ CD4+ cells in TDLNs and in tumor spleen increased with tumor growth. Analysis of these CD25+ CD4+ T cells in vitro confirmed expression of the Treg marker, Foxp3. In addition, their functional activity resembled that of Treg, as evidenced by a poor proliferative capacity; suppression of proliferation of CD25- CD4 or CD8T cells and inhibition of interferon-gamma release by CD25- CD4+ T cells. Reconstitution of Pan02-bearing Rag-/- mice with naive syngeneic CD25- CD4+ T cells induced CD25+ CD4+ Foxp3+ T cells in TDLNs, but not in the spleen. In contrast, Foxp3 was not detected in unreconstituted Pan02-bearing Rag-/- mice, or reconstituted mice bearing a TGF-beta-negative esophageal tumor. Furthermore, administration of neutralizing anti-TGF-beta antibody blocked the induction of Foxp3 in reconstituted Pan02-bearing Rag-/- mice. These results mimic earlier in vitro studies showing induction of Foxp3 through CD3 plus CD28 stimulation in the presence of TGF-beta. We conclude that Pan02 tumor promotes the prevalence of Treg, in part through the secretion of TGF-beta, which may result in immune evasion.

  • Glioblastoma cells block radiation-induced programmed cell death of endothelial cells.

    FEBS letters 2004 May 7

    Authors: Brown CK,
    We demonstrate that human umbilical vein endothelial cells (HUVEC) grown in co-culture (CC) with U87 glioblastoma cells transfected with green fluorescent protein (GFP-U87) exhibit resistance to radiation-mediated apoptosis. cDNA macroarray analysis reveals increases in the accumulation of RNAs for HUVEC genes encoding cell adhesion molecules, growth factor-related proteins, and cell cycle regulatory/DNA repair proteins. An increase in protein expression of integrin alphav, integrin beta1, MAPK(p42), Rad51, DNA-PK(CS), and ataxia telangiectasia gene (ATM) was detected in HUVEC grown in CC with GFP-U87 cells compared with HUVEC grown in mono-culture. Treatment with anti-VEGF antibody decreases the expression of integrin alphav, integrin beta1, DNA-PK(CS) and ATM with a corresponding increase in ionizing radiation (IR)-induced apoptosis. These data support the concept that endothelial cells growing in the tumor microenvironment may develop resistance to cytotoxic therapies due to the up-regulation by tumor cells of endothelial cells genes associated with survival.
