Objective: The aim of this study is to evaluate the perioperative and postoperative follow-up results of patients operated for a parotid mass.

Materials and Methods: A total of 66 patients who were operated between 2000 and 2011, were evaluated retrospectively.

Results: The mean age of the patients was 48,6. On the basis of post-operative histopathologic assessement, 61 of the cases were found to be primary benign, 3 of the cases  primary malignant and 2 of the cases secondary malignant. Pleomorphic adenoma was the most common in primary benign tumors group with 29 cases, Warthin tumors were in the second place with 14 cases. Adenoid cystic carcinoma, adenocarcinoma and expleomorphic adenoma were observed as primary malignant tumors. Both of the seconder malignant tumors were metastasis of squamous cell carcinoma. Sensitivity and specifity of the preoperative fine needle aspiration biopsy in the benign-malignant differentiation were found as 60 % and 96 %, respectively. Superfacial parotidectomy, total parotidectomy and radical parotidectomy were used as surgical procedures. In addition to this procedure, neck dissection was performed in several cases. The most frequent complication was temporary facial nerve paresis.

Conclusion: Fine needle aspiration biopsy is an effective diagnostic procedure for the benign-malignant differentiation of the parotid tumors. Superfacial parotidectomy is an adequate and efficient surgical procedure for the benign parotid tumors and complication risk is considerably low when applied carefully. For malignant tumors, superfacial, total or radical parotidectomy should be performed and when necessary, neck dissection and postoperative radiotherapy should be added to the treatment.

Aim: Gastric cancer is one of the leading causes of cancer-related deaths. Tumor budding has been
shown to be a prognostic factor in many cancers. In this study, we aimed to evaluate the prognostic
significance of tumor budding in intestinal-type gastric adenoc arcinoma.
Patients and Methods: A total of 152 cases diagnosed as intestinal type gastric adenocarcinoma in
the Pathology Clinic between 2015 and 2021 were included in the study. Tumor budding was grouped
as low, medium and high. Hematoxylin and eosin-stained slides were re-evaluated in terms of tumor
differentiation, lymphovascular invasion (LVI), perineural invasion (PNI), lymph node involvement, depth
of invasion (pT) and tumor budding.
Results: Tumor budding was low in 30.9% (n=47) of the subjects included in the study, moderate in 37.5%
(n=57) and high in 31.4% (n=48). Statistically, as tumor budding increased, tumor size increased (p<0,05),
follow-up times were shortened, survival time (p<0,05), and tumor differentiation (p<0,05) decreased. A
statistically significant correlation was observed between tumor budding and LVI (p<0,05), PNI (p<0,05),
pT(p<0,05), lymph node involvement(p<0,05), and mortality of the cases (p<0,05). No statistically
significant correlation was observed between tumor budding and gender, age, tumor localization and
operation type (p>0.05).
Conclusions: Tumor budding is associated with poor prognostic factors. As it may be important to guide
the treatment modality and follow-up, tumor budding status may be mentioned in routine pathology reports.

Purpose: Laryngeal squamous cell carcinoma poses a management challenge due to the lack of reliable prognostic markers. Although tumor budding (TB) has been shown to predict poor prognosis in some malignancies, its prognostic significance in laryngeal cancer remains uncertain in the literature. Therefore, the objective of this study is to evaluate the impact of TB on prognosis and its correlation with other established prognostic factors in laryngeal squamous cell carcinoma.

Patients and Methods: In the department of otolaryngology the files of 60 patients with laryngeal squamous cell carcinoma who underwent surgery, postoperative chemoradiotherapy between 2008 and 2015 were analyzed retrospectively. The patient’s history, family history, age, TNM (tumor, node, metastases) classification, radiological imaging, type of surgery performed, and the results of the pathological specimen were evaluated. PanCK immunohistochemical staining was performed on old paraffin block sections containing tumoral tissue, previously stained with Hematoxylin & Eosin. The TB scores were evaluated by the pathology department, and the association between all obtained parameters and clinicopathological variables was analyzed.

Results: Our findings showed a significant association between tumor budding and perineural infiltration, a known prognostic factor for laryngeal carcinoma (P=0.006). TB was found to be an independent risk factor for perineural infiltration and pathological lymph node involvement (p=0.003). Pathological lymph node involvement was also found to be an independent risk factor for lymphovascular invasion (p=0.028).

Conclusions: Our study provides evidence for a significant association between tumor budding and perineural infiltration, which are established prognostic factors in laryngeal carcinoma. This suggests that tumor budding may be an important factor in determining tumor prognosis.

\r\n Locally advanced rectal cancer is one of the best example that optimal outcomes are achieved with a multidisciplinary approach. The mainstay of curative treatment remains radical surgery; however, combine with radiotherapy is the optimal treatment to control local recurrence and to improve survival. To date, preoperative radiotherapy is shown to be superior than postoperatif radiotherapy. In this review, we aimed to evaluate the application methods, advantages and disadvantages of preoperative radiotherapy.

Objective: Most of the renal neoplasms are the epithelial and malign ones. The renal cell carcinoma (RCC), which is the most frequently seen malign renal tumor, consists of 2-4% of all the malign tumors seen among adult individuals and 80-90% of all the malign renal tumors. RCCs peak at sixties and seventies and its prevalence among males is two folds of its prevalence among females. RCCs have bad prognosis. The recurrence is seen in 40% of the cases, and the metastasis despite the early diagnosis was detected in 50% of cases. In present study, it was aimed to distribution of renal tumors in our hospital, discuss the prognostic factors such as the, pathological stage, nuclear grade and tumor diameter accompanied by literature information.

Patients and Method: By retrospectively scanning the records of Pathology Department of Medical Faculty, Fırat University, for the period between 1988 and 2009, 140 renal tumor cases were determined and the previous diagnoses, histological degrees, pathological stages of these cases were evaluated and the final diagnoses were taken as base in the present study. In pathologically staging (pT) of RCCs, TNM classification was used, whereas Fuhrman nuclear grading (FNG) was used in nuclear grading procedure. The patients were divided into different groups based on their genders and ages. The statistical analyses were performed in SPSS-12.0 software by using Chi-Square and Correlation tests.

Results: When compared to the literature in terms of the mean age, the present study involves relatively young population (mean age 57), and the majority was male (male/ female:1.1). The distributions of renal tumours, malign and benign subtypes, and RCC subtypes show similarities with the general literature. When examining the RCCs statistically, no significant relationship was found between diagnosis and age, and between nuclear grade and tumor diameter (p>0.05). In the present study, the RCCs with largest diameter were papillary type (9,78cm) ones, whereas the RCCs with lowest diameter values were classic type. A statistically significant relationship was observed between the benign, borderline and malign tumor diagnoses and diameters (p= 0.023). It was determined that approximately one-four of RCC cases were in highly pathological stage (21,6%, pT3a-3b). A direct proportional and statistically significant relationship was found between nuclear grade and diameter (p=0,002).

Conclusion: RCCs have poor prognosis and their frequency is increasing. Pathological stage, nuclear grade and diameter are the leading factors affecting the prognosis. As in our study, in retrospective studies involving old ages and not enough sampling, tumor diameter may be used as an alternative prognostic factor for pathological staging in tumors with a stage above pT2.

Abstract

Aim: Since clinical and prognostic heterogeneity is observed in diffuse large B-cell lymphoma (‎DLBCL) patients, it is vital to determine its prognostic and predictive factors. The frequency of these factors varies geographically and ethnically. We aimed to reevaluate and discuss the prognostic and predictive ‎factors of DLBCL patients who have been treated with R-CHOP in our ‎center based on the WHO 2017 revised 4^th edition.‎ We also investigated the incidence of EBV in DLBCL-NOS.

Patients and Methods: Patients with DLBCL-NOS diagnosed previously in our hospital between 2007-2017 and treated with ‎R-CHOP were included in the study. We evaluated the expressions of CD10, CD5, CD30, BCL-2, BCL-6, MUM-1, MYC, LMP-1, EBNA-2, Ki-67, and p53, by immunohistochemistry, and EBV encoded RNA by in situ hybridization in 104 cases of DLBCL-NOS. The Revised International Prognostic Index (R-IPI) score and the overall survival time ‎was ‎calculated.

Results: The study included 56 men (53.8%) and 48 women (46.2%). The median age was 64.5 years. In 59.6% of the patients, the disease had a nodal beginning, whereas in 40.4% of the patients it had an ‎extranodal presentation. High ‎stage (III-IV) was present in 26.5% of the GCB subtype and 43.6% of non-GCB subtype (p=0.049). A high ‎R-IPI score was observed in 40% of GCB subtype and 54.5% of non-GCB subtype (p=0.028). Survival was significantly lower in the non-GCB subtype (log-rank test p=0.003).‎ The EBV frequency was about 3% as it is reported in Western populations. The frequency of DEL status was 8.7%, indicating that it was associated with inferior survival (p=0.045). De novo CD5⁺ DLBCL ratio as 13% and it was also associated with inferior survival (p=0.013).  We also found CD30⁺ DLBCL ratio as 11.5%, but we could not establish a significant relationship with prognosis.

Conclusion: DLBCL-NOS requires detailed subtyping and elaboration of prognostic factors. ‎The frequency of DEL status and De novo CD5⁺ DLBCL indicated that it was associated with inferior survival. However, we could not establish ‎a meaningful relationship of CD30⁺ DLBCL with prognosis.‎ Three EBV positive cases were identified and two of them were classified as ‘EBV positive large B cell lymphoma’ according to the WHO 2017 revised 4^th edition.

Aim: Investigate the role of Magnetic Resonance Imaging (MRI) in the evaluation of response of the locally
advanced rectal cancer to the chemoradiotheraphy (CR T).
Patients and Methods: T2-weighted and Diffusion Weighted Imaging (DWI) of 24 cases with locally advanced
rectal cancer who have undergone total mesorectal excision 6-8 weeks following the CRT between 2015 and
2020 were evaluated retrospectively. The evaluated radiological parameters were as follows; Tumor morphology,
localization, length, mrT/mrN stages, and extramural vascular invasion (EMVI). Post-CRT MRI residue scoring
was performed (0: No residual tumor, 1: No significant residual tumor, fibrotic wall thickening, 2: Residual tumor
present). Regression grading was as follows; 1: No tumor, 2: Good response, mostly fibrosis, 3: Fibrosis and
mucin more than 50%, 4: Slight response, 5: No response.
Results: There was a significant decrease in the craniocaudal length of tumor and a significant increase
in the mean ADC of tumor after CRT (p=0.001). A significant and high correlation was observed between
histopathological T (pT) and post-CRT mrT (r=0.54, p=0.006). There was a significant correlation between pre-
CRT EMVI and perineural invasion (PNI) (r=0.53, p=0.008). A significant correlation was found between residue
scoring and regression grading (r=0.6; p=0.001), pT (r=0.48; p=0.02), and tumor length (r:0.51; p=0.01). There
was a significant correlation between regression grading and EMVI (r=0.43, p=0.036), PNI (r=0.46, p=0.02), pT
(r=0.41; p=0.048), pN (r=0.55; p=0.006), and metastatic/total lymph node ratio (r=0.46; p=0.02).
Conclusion: Post-CRT MRI is highly correlated with postoperative pathological evaluation of the locally
advanced rectal cancer. MRI is highly successful in re-staging as well as primary staging. The evaluation of
treatment response by MRI regression grading may contribute to the surgical planning.

Aim: Hypoxemia is a vital criterion used to determine prognosis in coronavirus disease (COVID-19)
cases. This study thus examined the effectiveness of capillary refill time (CRT) in defining hypoxiadependent
disease severity in COVID-19 patients.
Patients and Methods: This prospective study was conducted with COVID-19 patients and an agematched
healthy group. The optimum test ambiance was provided, and a stable smartphone platform
was used to record the measurements (in ms) to standardize our method. The captured videos were then
evaluated using a video processing program.
Results: In total, 39 patients with COVID-19 and 40 control groups participated in this study. The patients
were further divided into the moderate (n = 25) or severe group (n = 14) according to disease severity.
The mean oxygen saturation of both moderate/severe groups was above 94%. Per disease severity, the
CRT measurements were higher in the severe group than in the moderate group (p = 0.009). In patients
without lymphopenia (n = 18), CRT values were found to be increased in the severe group (p = 0.008).
The use of CRT in patients with Covid-19 was practicable (AUC: 0.91; 95% CI 0.848-0.978; P = 0.001).
Conclusions: Our results show that CRT prolongation can occur in patients with COVID-19. In patients
without lymphopenia and with normal O2 levels, detecting CRT prolongation may be a criterion for early
admission to ICU.

Abstract

INTRODUCTION

Acute mesenteric ischemia (AMI) is an acute abdominal disease which is age-related with possible bad prognosis; and while its morbidity and mortality rate is 10% in early diagnosis and treatment it may progress with 100% mortality when diagnosis and treatment are delayed.The aim of this study was to unearth the efficiency of neutrophil-to-lymphocyte ratio (NLR) which has recently been started to be utilized in the prediction of AMI prognosis and used as a prognostic factor in many diseases.

MATERIALS and METHODS:

The data of a total of 111 patients, who had undergone surgical procedures and diagnosed with mesenteric ischemia intraoperatively at Necmettin Erbakan University Meram Medical School’s General Surgery Clinic between 2005 and 2013 and whose diagnoses had later on been confirmed pathologically, were retrospectively evaluated within the scope of the study.

The demographic data of all patients (age, sex) were recorded. The hemogram results of the patients, analyzed with peripheral blood, were reviewed for preoperative evaluation. The surgical procedure performed, the part and length of the resected bowel based on pathology results, the duration of hospitalization, survey, presence of comorbidity, white blood cell count, creatinine values, and NLR of the patients were determined. The data were statistically analyzed.

RESULTS:

The patients who did not survive had a mean NLR of 24.77 ±10.38, while the same ratio was found to be 17.6±10.65 for survivors. The NLO value was found to be high in cases with mortality.

CONCLUSION:

AMI still proves to have high mortality in spite of the developments in imaging techniques and laboratory analyses. There is no specific laboratory analysis for early diagnosis. High preoperative NLR in patients suspected to have AMI may indicate bad prognosis.
