RESUMO
We aimed to evaluate the depth of myometrial invasion preoperatively with transvaginal ultrasound, magnetic resonance imaging, and frozen section examination techniques in patients diagnosed with endometrial cancer. Our study included 65 patients. Transvaginal ultrasound and magnetic resonance imaging were performed in study patients in the preoperative period. Frozen section examination was performed in all hysterectomy samples obtained from all study patients. Data were analyzed with SPSS Statistics 22.0 program. The sensitivity of transvaginal ultrasound in determining the depth of myometrial invasion was 88.64%, specificity 90.48%, positive predictive value 95.12%, and negative predictive value 79.17%. For magnetic resonance imaging, the sensitivity was 63.64%, specificity 95.24%, positive predictive value 96.55%, and negative predictive value 55.56%. In addition to the frozen section examination, which is the gold standard in determining the myometrial invasion depth, transvaginal ultrasound and magnetic resonance imaging have become commonly used methods for this purpose in recent years. Ultrasound examination performed by an experienced specialist is superior to magnetic resonance imaging as it is fast, inexpensive, and associated with higher sensitivity.

Objective: To assess whether more accurate mediastinal lymph nodes radiotherapy can be performed with fluorode oxyglu cosepositron emission tomogaphy/computed tomography. METHODS: The retrospective study was conducted at Inonu University Medical Faculty, Malatya, Turkey, and Afyon Kocatepe University Medical Faculty, Afyon, Turkey, and comprised record of patients histopathologically diagnosed with non-small cell lung carcinoma and who underwent fluorodeoxyglucose positron emission tomography / computed tomography between January 2013 and December 2016. Surgery and pathology reports of the patients were reviewed. Histopathologically proven malignant and benign lymph nodes were re-identified with fluorodeoxyglucose positron emission tomography / computed tomography imaging. Anatomical and metabolic parameters of lymph nodes were re-assessed by specialists and compared with histopathology reports. Maximum standardised uptake values were used to assess sensitivity, specificity, positive predictive value, and negative predictive values. SPSS 22 was used for data analysis. RESULTS: The study included 144 mediastinal lymph nodes related to 42 patients who had a mean age of 62.4±9.8 years (range: 41-79 years). In terms of subtypes of the primary squamous cell carcinoma was found in 24(57.2%) patients, adenocarcinoma in 12(27.5%), and other subtypes in 6(15.3%) patients. Of the 144 lymph nodes, 48(33.3%) were metastatic. Sensitivity, specificity, positive predictive value, and negative predictive value were 92.8%, 64.3%, 56.9%, and 94.7%, respectively when maximum standardised uptake value >2.5 was used as the malignancy criterion. When lymph node maximum standardised uptake value / liver standardised uptake value-mean>1.69 was used as the criterion, the sensitivity, specificity, positive predictive value, and negative predictive value were 95.83%, 91.67%, 85.2%, and 97.8%, respectively. When the same values with lymph node >8mm was used as the criterion, the four resultant values were 89.6%, 93.8%, 87.8%, and 94.7%, respectively. When lymph node was replaced with mean attenuation >35 as the criterion, the consequent values were 79.2%, 93.8%, 86.4%, and 90.0%, respectively. CONCLUSIONS: Lymph node maximum standardised uptake value / liver standardised uptake valuemean> 1.69 was associated with higher negative predictive value and more useful positive predictive value compared to maximum standardised uptake value >2.5. When this parameter was used along with short axis or mean attenuation value, there were no significant increase in positive predictive value, but there was a decrease in negative predictive value.

Polymyalgia rheumatica associated amyloidosis is an extremely rare condition that can be rapidly progressive with high morbidity and mortality and management is challenging. Tocilizumab is a monoclonal anti IL-6 receptor antibody which is in the therapeutic arsenal of polymyalgia rheumatica. The efficiency of tocilizumab in improvement of polymyalgia rheumatica activity score and decreasing steroid dose is well established, while efficiency in polymyalgia rheumatica associated amyloidosis has not been published. Herein, we reported a polymyalgia rheumatica patient with AA amyloidosis who was treated effectively with tocilizumab.
