The fourth limitation of the present study is that even though the procedure is applied by a single surgeon (using surgical loop), rats are fragile animals for anastomosis surgery due to their small size and differences that are not visible to the naked eye, which may have taken place during the surgery of each animal. We investigated whether tracheal stenosis surgery's success was related to the periods of the post-injury wound healing process and analyzed the availableness of biomarkers in determining the appropriate period for surgery. [4] Surgical treatments are applied in post-intubation tracheal stenosis patients with high effectivity, and studies have focused on reducing anastomosis tension and end-to-end anastomosis of healthy mucosa.

OBJECTIVE: The objective of the study was to determine the parameters that can be used to predict malignancy in persistent cervical lymphadenopathies. METHODS: We retrospectively reviewed the files of 162 patients diagnosed with persistent cervical lymphadenopathy who underwent an excisional biopsy in our department between January 2011 and October 2019. Patient demographics and the size, side, duration, and localization of lymphadenopathy were recorded, and their relationship with histopathological results was investigated. Multiple regression analysis was used to determine the relationship between clinical parameters and malignancy. RESULTS: Of the 162 patients, 91 (56.2%) were male and 71 (43.8%) were female, and the mean age was 45.40±20.41 (2-84) years. Male gender (OR=3.099; p=0.003), increasing age (OR=1.029; p=0.002), short duration of lymphadenopathy (OR=0.989; p=0.048), and neck level V (OR=2.604; p=0.031) patients had a statistically significantly higher risk of malignancy. There was no statistically significant relationship between the side and size of the lymph node and the risk of malignancy (p>0.05). CONCLUSION: In our study, male gender was determined to be the most predictive risk factor for malignancy in patients with cervical lymphadenopathy, followed by lymph node neck level, increased age, and duration of the disease.

Objectives: Ovarian cancer is a heterogeneous disease, where chronic inflammation plays a key role in carcinogenesis. In this study, it is aimed to analyze the relationship with prognosis and chemotherapy response to clinicopathological variables in epithelial ovarian cancers such as proliferation of PD-1 +, CD8 +, CD4 +, CD3 + T-lymphocytes infiltrating the tumor and tumor stroma. Matrial and methods: Seventy-six cases diagnosed with primary epithelial ovarian tumor from biopsy or surgical resection materials were included in the study. Immunreactivity of CD3, CD4, CD8, PD1 was evaluated immunohistochemically in lymphocytes in tumor infiltrating lymphocytes and stromal lymphocytes. Results: Seventeen (22.4%) of the cases were Type I, 59 (77.6%) of them were Type II ovarian carcinoma. PD-1 positivity was observed in stromal and intraepithelial lymphocytes in 22 (28.9%) of 76 cases. In the presence of PD-1 + T-lymphocytes that infiltrate tumor and stroma, disease-free survival are shorter (p = 0.037). The presence of stromal CD4 + and CD8 + T-lym-phocytes was more common in late stage patients (p = 0.012, p = 0.036; respectively). The disease-free and overall survival rate was statistically significantly shorter in the presence of CD8 + T lymphocytes (p = 0.009, p = 0.003; respectively). Conclusions: CD3, CD4 and CD8 may contribute to PD-1 mediated tumor control. Anti PD-1 therapy may be an alternative to chemotherapy in PD-1 positive patients. Identifying patients who do not respond to chemotherapy through PD-1 expression prior to immunotherapy will help develop potential personalized immunotherapy. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To determine the demographic characteristics of benign and malignant salivary gland tumors in our department in the last 15 years. METHODS: In this study, the files of the patients who underwent salivary gland surgery between 2004 and 2019 in our department were analyzed retrospectively. A total of 366 patients whose diagnoses of salivary gland tumor histopathologically confirmed were included in this study. The demographic data of the patients and tumor localizations were recorded, and their relationships with histopathological results were examined. RESULTS: Of the 366 tumors, 292 (80%) of them was originated from the parotid gland, 52 (14%) from the submandibular gland, and 22 (6%) from the minor salivary gland. The male: female ratio was found as 1.2:1, and the mean age of the patients was 50.37 years. A total of 259 (70.8%) tumors were benign, and 107 (29.2%) were malignant. The most frequent benign tumor was pleomorphic adenoma, with 121 cases (46.7%). While pleomorphic adenomas constituted the majority of the benign tumors of the submandibular gland and minor salivary glands, Warthin tumor was detected more than pleomorphic adenoma in the parotid gland. The most common malignant tumor was mucoepidermoid carcinoma, with 26 cases (24.3%). CONCLUSION: The distribution of the salivary gland tumors detected in our department was found to be substantially similar to other worldwide series. Unlike the literature, we concluded that salivary gland tumors were seen slightly more in males, minor salivary gland tumors were relatively rare and Warthin tumors were more frequently detected in our region.

Introduction: 18F-FDG PET/CT provides very effective results in detecting metastases of breast cancer. In our study, we investigated the relationship between maximum standard uptake value (SUVmax) and prognostic pathologic factors in breast cancer cases with isolated bone metastasis and whether there was any difference in terms of prognostic pathologic factors between the group with and without bone metastasis. Methods: Between 2013 and 2016, isolated bone metastases (55 female; 56±12 years; 32-87), and non-metastatic (46 female; 55±13 years; 30-81) patients who were referred to department of nuclear medicine and underwent 18F-FDG PET/CT for staging were included in the study. PET/CT images of patients and pathologic prognostic factors were evaluated retrospectively. SUVmax value of the most intense activity from metastatic bone lesions was calculated. p <0.05 was considered statistically significant. Results: In the metastatic group, there was no statistically significant relationship between measured SUVmax value of bone metastasis and pathologic prognostic factors. A statistically significant difference was found between the metastatic group and the non-metastatic group in terms of lymph node stage, lymphovascular/perineural invasion. The lymph node stage in the metastatic group was higher than the non-metastatic group. The presence of lymphovascular/perineural invasion in bone metastasis cases was more than in the non-metastatic group. Conclusion: In our study, it was determined that there was a relationship between the lymph node stage, lymphovascular/perineural invasion and formation of bone metastasis in breast cancer. Between SUVmax values and other factors in the metastatic group, no significant relationship was detected. [ABSTRACT FROM AUTHOR]
