Inflammation plays a role in the progression to cancer and it is linked to the presence of senescent cells. Ulcerative colitis (UC) is a chronic inflammatory disease that predisposes to colorectal cancer. Tumorigenesis in this setting is associated with telomere shortening that can be observed in the nondysplastic epithelium of UC patients with high-grade(More)
CONTEXT Detecting omental metastasis is crucial for staging and treatment of endometrial and ovarian carcinoma. OBJECTIVE To determine the optimal omental sampling for omentectomies to ascertain the stage of the disease in a cost-effective way. DESIGN We reevaluated 258 omentectomies that were performed due to ovarian or endometrial carcinoma. A total(More)
INTRODUCTION The association of systemic lupus erythematosus with malignancies is an uncommon occurrence. We present the case of an osteosarcoma of the urinary bladder developing in a patient with a prolonged history of active systemic lupus erythematosus. This is a previously unreported association. Primary osteosarcoma is an extremely rare disease in the(More)
BACKGROUND Clinical and imaging features of patients with orbital leukaemia primarily involving extraocular muscles were evaluated. METHODS This retrospective case series includes patients with leukaemia whose only ophthalmic manifestation was extraocular muscle enlargement. Demographic data, clinical information on the systemic disease, prominent ocular(More)
PURPOSE Assessment of expression levels of Wwox, Wwox-interacting proteins Ap2alpha, Ap2gamma, and ErbB4, the Ap2gamma transcriptional target protein Her2, and the possible Ap2alpha transcriptional target PrkaRIalpha, in breast cancers, to determine their roles in tamoxifen resistance. The hypothesis was that sequestration of Wwox interactors in the(More)
BACKGROUND The expression of fragile histidine triad protein (Fhit) and WW domain-containing oxidoreductase protein (Wwox), tumor suppressors that are encoded by fragile (FRA) loci FRA3B and FRA16D, are lost concordantly in breast cancers. In the current study, the authors examined correlations among Fhit, Wwox, the activator protein 2 transcription factors(More)
Presented herein is a case of diffuse fatty infiltration of amyloid goiter in a 58-year-old woman with chronic renal failure. Bilateral total thyroidectomy was performed due to symptoms of dysphagia and hoarseness. Macroscopic and microscopic examination showed that almost all thyroid follicles were replaced by fat cells. Hyalinized stroma intervening the(More)
Landmark studies of the status of DNA damage checkpoints and associated repair functions in preneoplastic and neoplastic cells has focused attention on importance of these pathways in cancer development, and inhibitors of repair pathways are in clinical trials for treatment of triple negative breast cancer. Cancer heterogeneity suggests that specific cancer(More)
To analyze prognostic factors, the role of lymphadenectomy and postoperative adjuvant treatments in patients with uterine leiomyosarcomas (LMS). Sixty-three patients with uterine LMS are retrospectively analyzed with respect to both DFS and OS. Multivariate DFS analysis revealed percentage necrosis to be the unique factor to be significant (median DFS was(More)
Pelvic actinomycosis is a chronic granulomatous suppurative disease caused by actinomyces israeli. Intravenous penicillin is the preferred antimicrobial but it requires hospitalization up to one month. An outpatient treatment strategy would be cost effective and a good choice for patients. Here we present three cases in which intramuscular ceftriaxone was(More)
