    Isolated jejunal metastasis in a patient with cervical cancer: A case report
    (2015) Onal, Cem; Nursal, Gul Nihal; Torer, Nurkan; Kayaselcuk, Fazilet; 25949229
    Background: In approximately 8% of cervical carcinoma patients, gastrointestinal tract is involved, most commonly the rectosigmoid portion, because of local extension. Isolated metastases to small bowel are exceedingly rare. Case report: We present a case of a 63-year-old woman with cervical cancer who developed isolated jejunal metastasis 8 months after postoperative chemoradiotherapy. The patient was alive with no evidence of disease 6 months after resection of metastasis. Very few cases have been reported concerning squamous cell carcinoma of the cervix with documented metastases to the small bowel. There is only one published case report of cervical cancer with multiple metastases to the small intestine and jejunum. To our knowledge, this is the first case of cervical cancer with isolated jejunal metastasis, which was initially demonstrated with positron emission tomography and confirmed histopathologically. Conclusion: Although the exact mechanism underlying the isolated metastasis is unknown, hematogenous spread or tumor seeding during surgery may play a role. (C) 2015 Greater Poland Cancer Centre.

    The Effects of Cinacalcet Treatment on Bone Mineral Metabolism, Anemia Parameters, Left Ventricular Mass Index and Parathyroid Gland Volume in Hemodialysis Patients with Severe Secondary Hyperparathyroidism
    (2016) Torun, Dilek; Yildiz, Ismail; Micozkadioglu, Hasan; Nursal, Gul Nihal; Yiğit, Fatma; Ozelsancak, Ruya; 26787561
    The aim of this study was to investigate the effects of cinacalcet therapy on anemia parameters, bone mineral metabolism, left ventricular mass index (LVMI) and parathyroid gland volume in hemodialysis (HD) patients with secondary hyperparathyroidism. Twenty-five HD patients (M/F: 11/14, mean age: 45.2 +/- 17.9 years, mean HD duration: 96.4 +/- 32.7 months) were included in this prospective pilot study. The indication to start calcimimetic therapy was persistent serum levels of parathyroid hormone (PTH) > 1000 pg/mL, refractory to intravenous (i.v.) vitamin D and phosphate-binding therapy. The initial and one-year results of adjusted serum calcium (Ca+2), phosphate (P), Ca x P product, PTH, hemoglobin (Hb) and ferritin levels, transferrin saturation index (TSAT), median weekly erythropoietin (EPO) dose, LVMI, and parathyroid volume by parathyroid ultrasonography were determined. There were no differences between pre-and posttreatment levels of serum Ca+2 (P = 0.853), P (P = 0.447), Ca x P product (P = 0.587), PTH (P = 0.273), ferritin (P = 0.153) and TSAT (P = 0.104). After 1 year of calcimimetic therapy, the Hb levels were significantly higher than the initial levels (P = 0.048). The weekly dose of EPO decreased with no statistical significance. The dose of cinacalcet was increased from 32.4 +/- 12.0 to 60.0 +/- 24.4 mg/day (P = 0.01). There were no differences between the pre-and post-treatment results regarding weekly vitamin D dose, parenteral iron dose, LVMI and parathyroid volume. The results of our study suggest that cinacalcet therapy might have an additional benefit in the control anemia in HD patients.
