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.

Aim: Gallbladder cancer is an uncommon, but aggressive tumor. Its prognosis is poor and the most cases are incidentally detected in histopathological examinations of cholecystectomies due to benign diseases. With the era of laparoscopic cholecystectomy, the number of cases detected in early stage is increasing. In this study, we aimed to evaluate the rate of cancer encountered and the distribution of non-cancer diagnoses in cholecystectomy materials sent to our department, together with the literature findings.

Materials and Methods: The results of the cholecystectomy materials sent to the pathology laboratory and examined routinely in 2016-2017 were retrospectively evaluated by forming diagnostic groups. Clinical preliminary diagnoses, demographic informations (age, sex), and pathology reports of the patients were reviewed.

Results: We included a total of 1000 cholecystectomy materials into the study. Two of the 7 patients who presented with malignancy were incidentally diagnosed and underwent laparoscopic cholecystectomy with the preliminary diagnosis of cholelithiasis, with the primary focus was gallbladder in one patient, and the other was compatible with colonic adenocarcinoma infiltration. Preoperative and / or perioperative malignancy was detected in the remaining 5 patients. A large proportion (> 90%) of the other cases had chronic or chronic active cholecystitis and low rate of acute cholecystitis included gastric heterotopia found in 2 (0.2%), tubular adenoma in 1 (0.1%), tubulovillous adenoma in 1 (0.1%), adenomyoma / adenomyomatosis in 4 (0.4%), polyp in 6 (0,6%) and dysplasia (Biliary intraepithelial neoplasia, BilIN) in 5 (0.5%) patients.

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.

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.
