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: It was aimed to investigate  the relationship of disease clinical stage between the maximum diameter of primer lesion (LEGÇ), maximum of standardized uptake value (SUVmax), mean of standardized uptake value (SUVmean), tumor volüme (TV) and total lesion glycolysis (TLG) values derived from positron emission tomography/computed tomography (PET/CT) images.

Method: The information of 130 lung cancer patients diagnosed histopathologically between 01.01.2012 and 31.12.2014 in Necmettin Erbakan University Nuclear Medicine Department of Meram Medical Faculty scanned for PET-CT for lung cancer diagnosis and staging,  were included in this study. The values of the maximum diameter of primer lesion, SUVmax, SUVmean, TLG and MTV derived from PET-CT scanning and their histopathological subtypes, other clinical and radyological information of patients were noted. The non-small cell lung cancer patients were graded according to tumor diameter, nodal and involvement metastasis (TNM) staging system using clinical information, PET-CT and other radyological test results if any. On the other hand, the small cell carcinoma diagnosed were categorised as limited or extensive stage.

Findings: In this study, the mean age of 118 men and 12 women,  totally 130 patients, was evaluated  63,46 ±9,96 ( range 40-87 age ). The patients were classified as 106 non-small cell lung Cancer (NSCLC) (81.5%) ve 24 small cell lung cancer (SCLC) (18.5%).  The  histopathologically diagnosed NSCLC patients were consists of  62 squamous cell cancers, 39 adeno cancers, and 5  other types (3 carcinoid tumors, 1 large cell cancer and 1 sarcomatoid tumor). 

Results: In our study, it was observed that there was no significant relationship between the maximum diameter of the lesion, SUVmax, SUVmean, MTV and TLG values among SCLC and NSCLC patients. Additionally, it was also found that there was no correlation between these parameters and the SCLC stage.  The maximum diameter of the lesion, SUVmax, SUVmean, MTV and TLG parameters were related with stage.

Conclusion: Higher SUVmax, SUVmean, TV, and TLG values of the primary tumor were determined to predict the more advanced clinical stage in NSCLC. This relationship between metabolic parameters and the clinical stage suggest that PET / CT may be valuable in terms of providing prognostic information in NSCLC.

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.

Aim: In this study, we aimed to present our 10-year experience regarding clinicopathology characteristics and
overall survival of 69 patients with adenocarcinomas of esophag ogastric junction (AEJs).
Patients and Methods: A total of 69 consecutive patients diagnosed with AEJ and operated in our clinics
were included in the study. Patients’ demographic characteristics; laboratory parameters, surgical resection
approach; TNM stages; resection extent; total number of removed lymph nodes; tumor localization; presence
of lymphatic, vascular and perineural invasion and overall survival (OS) status were recorded. The patients
were divided into two groups as Siewert Type II and Siewert Type III.
Results: There was no statistically significant difference between the groups in terms of age (p=0.696)
and gender (p=0.140). Distribution of T stage was statistically significantly different between the groups
(p=0.026). OS was found to be significantly higher in patients at R0 level compared to those at R1 level. OS
was statistically significantly higher in patients without lymphatic, vascular and perineural invasion. 1-year OS
was determined as 83.50%, 3-year OS as 49.10% and 5-year OS as 43.60%. The risk of mortality increased
by 8.63 folds in the presence of perigastric fat infiltration, 12.60 folds in the case of vascular invasion and
13.45 folds in the case of perineural invasion. The survival rate was found as 51% and 41% in the Siewert
Type II and Type 3 patients at median 10-year follow-up.
Conclusion: This study had successfully evaluated the clinicopathological characteristics and overall
survival, and demonstrated that Siewert II tumors and Siewert III tumors had similar survival outcomes.
Further comprehensive multicenter studies with larger series and long-term studies are needed to provide
contribution to the existing evidence on outcomes of patients w ith AEJs.

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.

\r\n Objective: Early diagnosis of cutaneous squamous cell carcinomas (CSCC) is the most important factor affecting prognosis and most patients have a good prognosis. Some patients defined as high-risk group have high rates of regional recurrence and distant metastasis, and follow an aggressive course. In addition, recently numerous studies have being performed for determining the importance of sentinel lymph node sampling, and sentinel lymph node (SLN) positivity has been associated with a poor prognosis. In this study, we aimed to determine prognostic importance of SLN outcomes in patients with high-risk patients diagnosed with CSCC.

\r\n Patients & Methods: A total of 29 patients who underwent excisional operation in various body regions with the diagnosis of CSCC between 2009 and 2017, with available complete clinical and pathologic data were included in the study. At least 9-month clinical follow-up results, high risk factors and sentinel lymph node biopsy outcomes of the patients were recorded and analyzed. Patients with at least one of the American Joint Committee on Cancer (AJCC) criteria were considered as high-risk group.

\r\n Results: Twenty-five of the 29 CSCC patients were in the high-risk group. SLN positivity rate was 12% (n: 3/25) in the high-risk CSCC patients, all patients in the low-risk group had negative SLNs. All patients with SLN positive underwent local complementary lymphadenectomy, and all of these patients were re-operated due to recurrence. The rate of recurrence was found as 100% (n= 3/3) in high-risk CSCC patients with positive SLN, and 18% (n= 4/22) in high-risk CSCC patients with negative SLN. High recurrence rates (41.6%) and SLN positivity were observed in patients with hand-foot localizations.

\r\n Conclusion: High rates of local recurrence may be seen during progression of the disease in SLN positive patients. Hand-foot localization of CSCCs can be considered as a high risk factor regardless of a tumor diameter should be above 0.6 cm.

Metastasis of lobular breast cancer to the reproductive organs is an extremely rare condition. The followup of internal genital metastases for patients who received tamoxifen and chemotherapy after breast cancer surgery has important clinical significance. Here, we introduce such a patient who applied to our hospital and received treatment.

ABSTRACT

Objective: Endometrial cancer is the most common malignancy of the female genital tract and the fourth leading cancer among women. Our aim is to share the surgical treatment and results of endometrial cancer cases in our gynecological oncology clinic.

Material and Methods: In this study, the records of 164 endometrial cancer patients operated by the same surgical team between 2009-2019 were reviewed retrospectively. The clinical, surgical and histopathological features of the patients are presented here. Four patients who had sarcoma as a result of pathology, 7 patients who underwent complementary surgery and 1 patient with a second primary tumor were not included in the study.

Results: The mean age of the patients included in our study was 61.3 and the mean body mass index was 25.8. According to the postoperative pathology results; mean tumor size was 3.4 cm and mean number of collected lymph nodes was 28.8. Lymph node metastasis was observed in 19 patients and all of the metastases were in pelvic lymph nodes. Endometrioid type adenocarcinoma was seen in 81% of the patients. Myometrial invasion > 50% in 81 patients (49.4%). Twenty patients (12.2%) had cervical involvement, 11 patients (6.7%) had adnexal involvement and 28 patients (17.1%) had lymphovascular area invasion. 76 patients (46.3%) were grade 1, 61 patients (37.2%) were grade 2, 19 patients (11.6%) were grade 3. When the patients were staging according to the FIGO system in 2009, 70 (42.7%) stage 1A, 58 (35.4%) stage 1B, 12 (7.3%) stage 2, 3 (1.8%) stage 3A 17 patients (10.4%) were stage 3C1 and 4 patients (2.4%) were stage 4.

Conclusion: Endometrial cancer is the most common gynecological cancer, and it is usually diagnosed at an early stage as a result of early signs. Tumor size, depth of myometrial invasion and histopathologic grade are used to evaluate the risk of the disease, but studies with a higher number of high stage patients will be more useful in determining the risk.

\r\n Brown tumors are benign, but locally aggressive tumors that may emerge as a rare complication of prolonged hyperparathyroidism. They may be clinically and radiologically confused with bone metastases. Browns tumors show increased metabolic activity on F-18 FDG-PET/CT just as metastatic bone lesions. In this study, we present a patient who underwent PET/CT to seek a primary focus with the presumed diagnosis of  multiple bone metastasis, and Brown tumor was suspected because no primary focus was detected on imaging and increased FDG enhancement was seen in parathyroid locations, and the diagnosis was confirmed with further investigations. Herein, we aimed to underline that Brown tumors should be kept in mind in the differential diagnosis in patients who are clinically and radiologically considered to have bone metastasis. 

Purpose:

Primary and metastatic digestive system malignant melanomas are extremely rare. In our study, we aimed to compare lymph node metastasis with clinical and pathological parameters in gallbladder, stomach, small intestine and anorectal region malignant melanomas.

Materials and methods:

This retrospective study included 20 cases diagnosed with malignant melanoma in the gastrointestinal tract organs between January 2010 and January 2020 at XXXXXXXXXXXX. In our study, we wanted to evaluate the relationship between regional lymph node metastasis and age, gender, tumor localization, tumor size, extraintestinal melanoma history, melanin pigment, neutrophil-lymphocyte ratio and post-diagnosis life span in primary and metastatic malignant melanoma cases. We also reviewed the origin and literature of the cells from which melanoma originates in the digestive system.

Results:

There was a statistical relationship between tumor diameter and regional lymph node metastasis (p =0.000). As the tumor diameter increased, the lymph node metastasis rate increased. There was a relationship between survival and gender, tumor localization, distant metastasis, primary and metastatic digestive system melanoma (all p <0.05). Most of the men and those who did not metastasize away from the digestive system were alive. All patients with melanoma metastases to the digestive system and all patients with gallbladder and small intestine localization were alive. Our 70 year old patient with gallbladder primary malignant melanoma was the oldest patient we could identify in the literature.

Conclusions:

Regardless of cutaneous or origin, all melanomas originate from melanocytes, cells derived from embryological nerve crest. Malignant melanoma can be primary in every region, more frequently in the anorectal region in the gastrointestinal tract. The most common metastasis is to the small intestine. Accurate diagnosis is vital in places where it is rarely seen, such as the digestive system. Recently, in metastatic melanoma, immuno-oncological agents are used in adjuvant therapy to help prevent metastatic spread of the disease. Thanks to these treatments, it is reported that more than half of patients with melanoma who have the risk of metastasis after surgical resection provide recurrence-free survival. Although it is very rare, it should be kept in mind that there may be primary or metastatic malignant melanoma in the evaluation of digestive system biopsies.

Aim: The aim of this study was to investigate the prognostic significance of extracapsular invasion and its
relationship with clinicopathological data in gastric cancer .
Patients and Methods: A total of 190 patients with primary gastric carcinoma underwent total and
subtotal gastrectomy between 2013 and 2020 were included in the study. 133 (70%) were men, and 57
(30%) were women. Tumour invasion beyond the lymph node capsule was diagnosed as extracapsular
involvement. and evaulated in addition to histological type, lymph node positivity, lymphovascular and
perineural invasion, depth of invasion, and numbers of lymph no de metastasis.
Results: 136 patients (71.4%) had lymph node metastasis. Of these, 87 patients (64%) had extracapsular
invasion. Of the cases with extracapsular invasion, 36 (65.5%) were differentiated and 51 (63%) were
undifferentiated and perineural - lymphovascular invasion was seen in 68 (68%) and 80 (68.4%) cases,
respectively. A statistically significant association was observed with extracapsular invasion in terms of
perineural invasion (p=0.01), lymphovascular invasion (p=0.008) and depth of invasion (p=0.001) and
number of metastatic node (p=0.001). Extracapsular invasion was not associated with sex, histological
type, and resection type. In the multivariate analyse, the risk of extracapsular invasion is 5,501 higher
in those with cardia localization. Those with perineural invasion have an 11,44 higher risk of having
extracapsular invasion.
Conclusion: Cases with extracapsular invasion are associated with poor prognostic parameters. It
should be included in the future staging system of gastric cancers and pathology reports should include
information about extracapsular invasion.

Aim: Mesenchymal tumors of the gastrointestinal tract other than gastrointestinal stromal tumors are rare and most of them are benign. The aim of this study to reveal the clinical and pathological features of non-gastrointestinal stromal tumor mesenchymal tumors of the gastrointestinal tract.

Materials and Methods: All gastrointestinal endoscopic and surgical resection materials, between 2008-2018, were retrospectively reviewed. Cases diagnosed with mesenchymal tumor other than gastrointestinal stromal tumors were included.

Results: Twenty four lipomas, 14 inflammatory fibroid polyps, six leiomyomas, four lymphangiomas, four hemangiomas, four schwannomas, two neuromas, two malignant melanomas, one leiomyosarcoma, one granular cell tumor and one Kaposi sarcoma were detected. The median ages of the cases were 61 years (29-87), the median tumor size was 1.5 cm (0.2-14). Thirty seven (58.7%) cases were female and 26 (41.3%) were male. They caused nonspecific symptoms. No recurrence or metastasis was detected after excision in benign tumors regardless of the pathological diagnosis.

Conclusion: Non-gastrointestinal stromal tumor mesenchymal tumors of the gastrointestinal tract are mostly small and benign tumors that can be seen at any age and are frequently seen in women. The most common ones are lipomas and inflammatory fibroid polyps. Most gastric tumors cause dyspeptic complaints and intestinal tumors cause abdominal pain, nausea or vomiting, as well as some of the intestinal tumors lead to serious, even fatal clinical situations such as acute and chronic bleeding, obstruction, perforation, volvulus or intussusception. For benign tumors’ treatment, excision is sufficient, they do not exhibit recurrence or metastasis.

Purpose: It was aimed to present the clinical and functional results of the patients who underwent tumor resection and endoprosthetic reconstruction due to malignant tumor around the elbow.

Methods: 14 patients who underwent tumor resection and endoprosthetic reconstruction due to malignant tumor in the elbow circumference between 2011-2018 in our clinic were included in the study. While 4 of the patients were primary tumors (1 fibromixoid sarcoma, 1 leimyosarcoma, 1 multiple myeloma and 1 ewing sarcoma), 10 were distant organ metastases (4 breast cancer, 3 lung cancer, 1 stomach cancer, 1 renal cell cancer and 1 thyroid cancer). Musculoskeletal Tumour Society (MSTS) score and Mayo elbow performance score (MEPS) and survival were evaluated.

Results: The minimum follow-up period of the patients was 7 months, and the maximum follow-up period was 55 months. The mean MEPS score of the patients was 67.5 ± 12.0 (range, 45-90), and the mean of the MSTS score was 19.4 ± 2.3 (range, 16-24). Recurrence occurred at follow-up in 3 patients and exitus at follow-up in 7 patients. In this study, the median survival time of the patients was 44 months. The 1-year survival rate was 70.1% while the 3-year survival rate was 54.5%.

Conclusion: Pain and functional results are satisfactory in patients who undergo tumor resection and endoprosthetic reconstruction due to malignant tumor around the elbow. In the future, studies with larger patient series are needed.

Aim: We aimed to retrospectively analyze and present the findings of patients diagnosed with esophageal
cancer and staged using 18F-Fluorodeoxyglucose (18F-FDG) Positron Emission Tomography/Computed
Tomography (PET/CT) imaging.
Patients and Methods: Thirty-seven patients diagnosed with esophagus who were staged with 18F-FDG
PET/CT in our hospital between February 2015 and February 2020 were included in this study. Patients'
age, gender, localization of the primary tumor and 18F-FDG PET/CT maximum standardized uptake value
(SUVmax), findings of metastases to mediastinal, abdominal and cervical lymph nodes, lung, liver, bone and
other areas were retrospectively evaluated as.
Results: The meanage of the patients was 66,97 ± 14,54 years. 20 patients (54%) were male, 17 patients
(46%) were female. 10 patients (27%) had upper esophagus tumors, 23 patients (62%) had lower esophagus
tumors, 4 patients had middle esophageal tumors (11%). The pathological diagnosis of 23 patients was
squamous cell ca, 14 patients were adeno ca. The mean of primary tumor SUV max was measured as 14,09
± 6,36 in all patients. The mean primary tumor SUVmax of the patients diagnosed with squamous ca was
14,51 ± 6,63, and the mean of primary tumor SUV max of the patients diagnosed with adeno ca was found to
be 13,40 ± 6,03. Progression was observed in 7 of 9 patients whose treatment and follow-ups were continued
in our hospital, and regression was observed in 2 of them.
Conclusion: In the initial staging of patients diagnosed with esophageal ca, 18F-FDG PET/CT is an
increasingly useful imaging method. Our study supports this.

The most common therapeutic method for early stage distal esophageal cancers and proximal stomach
cancer is surgery. One of the challenges in esophageal surgery is to maintain gastrointestinal continuity.
The neoesophagus is transferred from the posterior, mediastinal, or retrosternal areas to the cervical
region. A 61-year-old male patient with esophageal cancer had received transhiatal total gastrectomy,
distal esophagectomy, and Roux-en-Y esophagojejunostomy. Right thoracotomy had been performed due
to anastomotic leak with the esophageal stump left behind. Left thoracotomy and metastasectomy were
also performed due to lung metastasis. The left colon was transpositioned from the presternal area to
the cervical region for reconstructive purposes. Physicians should bear in mind that the conduit can be
advanced in the presternal area as the last resort for its localization in esophageal surgery. The aim of this
study was to present, along with literature review, the case of a patient with distal esophageal cancer for
whom presternal colonic transposition was performed with the es ophageal stump left behind.

Cancer is a serious genetic disease caused by a series of disorders in the genome. Development of hightroughput sequencing approaches as well as the publication of large-scale projects have enabled the identification of several non-coding RNA molecules that are differentially expressed in various types of cancer. It has been reported that ncRNA transcripts such as long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have critical roles in the development and progression of cancer and can be used in the diagnosis/treatment of cancer. In particular, miRNAs are small RNA molecules which control gene expression at the post-transcriptional level and play critical roles in the important hallmark capabilities of cancers such as metastasis, invasion, cell proliferation, differentiation, and angiogenesis. Similarly, lncRNAs have also been identified as RNA transcripts that have important roles in the understanding of the molecular mechanism of cancer. Accordingly, in this comprehensive review, functional ncRNA molecules without protein coding capacity such as miRNAs, lncRNAs, and T-UCRs and the hallmarks of cancer were discussed together with a current perspective.
