Challenges and facilitators in child-friendly healthcare from the perspective of pediatric emergency nurses: A qualitative study.

PURPOSE: This study aimed to determine pediatric emergency nurses' experiences and opinions regarding child-friendly care within Watson's Human Care Model framework. DESIGN AND METHODS: This study is qualitative research conducted with nurses in the pediatric emergency unit of a university hospital between 06 March and 06 April 2024. This study used a purposive sampling method and conducted semi-structured interviews with 17 nurses. All interviews were audio recorded and transcribed. Inductive thematic analysis method was used. The study was written based on the COREQ checklist. FINDINGS: This study determined two themes, five sub-themes, and 13 categories. The theme "challenges to child-friendly healthcare implementation" included a lack of physical space and agitated and violent families. It has been reported that physical space, especially where privacy is not protected, makes child-friendly care complex, and the violent reactions of families are significant obstacles. The second theme, "facilitators for an ideal child-friendly pediatric emergency unit," included the design of the pediatric emergency unit/improving physical environment, availability of appropriate equipment, and effective communication strategies. This theme emphasizes the importance of colorfully designing the physical space and equipment in a way that does not scare children. CONCLUSION: It has been determined that the healing environment and care processes are essential for child-friendly care. During the care processes, communication according to the age of the children and communication with agitated families was emphasized as an essential component of care. PRACTICE IMPLICATIONS: The study results will guide hospital management, healthcare professionals working in the field, and future studies on designing the child-friendly emergency unit that children deserve.

A picture of hope: From the perspective of adolescents with cancer-A phenomenological-visual qualitative study.

This study aims to investigate the phenomenon of hope in adolescents diagnosed with cancer and examine adolescents' lived experiences of hope. The study was conducted between November 2022 and March 2023. The study used a phenomenological-visual qualitative research design with 20 adolescents in the pediatric oncology ward. The purposive sampling method was used in the study. Data were collected using "Descriptive Characteristic Form," "Semi-structured Interview Form," "Drawing Technique," and "Mutual Storytelling Technique". The adolescents were instructed, "Let us draw our hopes," and asked to draw pictures. Each adolescent was interviewed about the drawings and asked four semi-structured questions. Audio recordings of the interviews were made and transcribed. A hermeneutic phenomenological approach was used in the analysis of the data. Two main themes and four subthemes were identified in the study. Metaphorical and conceptual context was included in the theme of symbolizing and linking hope. Two subthemes, facilitators and barriers, were identified in the main theme of rooting hope. The study sheds light on hope experiences in adolescents receiving cancer treatment and guides healthcare professionals.

Effect of tumor-infiltrating immune cells (mast cells, neutrophils and lymphocytes) on neoadjuvant chemotherapy response in breast carcinomas.

INTRODUCTION: Despite screening, the incidence of breast cancer is increasing worldwide. Neoadjuvant chemotherapy (NAC) response is one of the most important parameters taken into consideration in surgery, optimal adjuvant chemotherapy planning and prognosis prediction. Research on predictive markers for the response to NAC is still ongoing. In our study, we investigated the relationship between tumor-infiltrating neutrophils/mast cells/lymphocytes and NAC response in breast carcinomas. MATERIAL AND METHOD: Study included 117 patients who were diagnosed with invasive breast carcinoma using core needle biopsy. In these biopsies tumor-infiltrating neutrophils/mast cells/lymphocytes were evaluated and Miller Payne Score was used for NAC response. RESULT: 53 patients exhibited high TILs, 36 had high TINs, and 46 showed high TIMs. While pathological complete response was 27 % in all patients, it was 38 % in high TINs patients, 35 % in high TILs patients, and 28 % in high TIMs patients. High TIMs were observed to be statistically associated with survival. TILs, TINs, nuclear grade, ER, PR and HER2 expression, Ki-67 proliferation index were found to be associated with the Miller - Payne score. In multivariate analysis, TINs, nuclear grade, pathological stage, and molecular subtype were found to be independent risk factors for treatment response. CONCLUSION: TINs have better prognostic value to predict neoadjuvant treatment than TILs. High TIMs are associated with increased overall survival. The inclusion of TINs in NAC response and TIMs in overall survival in pathology reports and treatment planning is promising in breast carcinomas as they are simple to use and reproducible markers.

Effect of mHealth-based relaxation program on stress coping and anxiety levels in mothers of children with cancer: A randomized controlled study.

OBJECTIVE: This study aimed to explore the effects of a mHealth-based relaxation program on anxiety and stress coping levels in mothers of children with cancer. METHODS: This randomized controlled, single-blind, parallel-group trial was conducted in the pediatric hematology-oncology unit of a university hospital. The study was completed by 50 mothers (intervention group: n = 25; control group: n = 25). The mothers in the intervention group participated in a mHealth-based relaxation program for eight weeks (including progressive muscle relaxation, guided imagery, and the four-leaf clover of mindfulness). Videos of the relaxation program were sent to mothers' WhatsApp accounts. The mothers in the control group received routine care. The State-Trait Anxiety and Stress Coping Scales were administered during the first and eighth weeks. The registration number of this study on ClinicalTrials.gov is NCT05807295. RESULTS: Mothers who participated in the relaxation program had lower anxiety levels and higher stress-coping scores than those in the control group (p < 0.05). CONCLUSION: Progressive muscle relaxation exercises, guided imagery, and cognitive-based therapeutic approaches were effective in reducing mothers' anxiety and stress coping. PRACTICE IMPLICATIONS: Pediatric oncology nurses can apply mHealth-based relaxation programs to support caregivers, particularly mothers. In this way, ensuring the continuity and integrity of care is easy.

Effectiveness of Virtual Reality in Anxiety and Pain Management in Children and Adolescents Receiving Cancer Treatment: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

TRIALS: The study aimed to investigate the effect of virtual reality interventions on relieving pain and anxiety in children and adolescents receiving cancer treatment. A search that involved Cochrane Library (comprising Cochrane Central Register of Controlled Trials (CENTRAL)), PubMed, ProQuest, MEDLINE, Web of Sciences, Science Direct, and Scopus electronic databases covering the records from January 1, 2000 up to May, 2023 was conducted to determine randomized controlled trials that could be included in our study. The results of the search were limited to "anxiety and pain, adolescents, children, virtual reality, cancer." Of the 160 articles that were reached during the search, seven were found eligible based on inclusion criteria. Hedges' g effect size was calculated for each article. Random effects model was used to test effect sizes and moderator variables. The registration number of this meta-analysis on PROSPERO is CRD42022304737. The outcomes were pain and anxiety. Compared with standard care, virtual reality had a medium and significant effect on anxiety (g = 0.60, 95% CI: [- 1.05 - 0.15]) and pain (g = - 0.667, 95% CI: [- 1.08- -0.24]). In addition, age has been identified as an important moderator in the use of virtual reality in pain management. This meta-analysis shows that virtual reality applications are effective interventions for reducing pain and anxiety in the field of pediatric oncology. However, it is necessary to carry out randomized controlled trials that have large samples for evidence-based virtual reality applications in pediatric oncology.

The experiences of mothers of children with food allergy: A qualitative study.

BACKGROUND: Food allergies adversely affect the quality of life of the child and family, as they require lifelong treatment and follow-up. This study aims to examine the experiences of mothers who have children with food allergies within the framework of the biopsychosocial-spiritual model. METHODS: This study, using a qualitative research design, was carried out with mothers of children followed up with food allergy in the pediatric allergy outpatient clinic of a university hospital between December 15, 2022 and January 05, 2023. Purposive sampling method was used in the study and semi-structured interviews were conducted with 12 mothers. All interviews were audio recorded and transcribed. Inductive thematic analysis method was used. The study was written based on the COREQ checklist. FINDINGS: Three themes, eight sub-themes, and 19 categories were identified: The effects of the disease on the physical health of the child and mother in the biological effects theme; psychosocial responses to disease, adaptation to treatment, future anxiety, coping strategies, and communication/interaction in the psychosocial effects theme; search for purpose-meaning in life and understanding belief/basic human values in the spiritual effects theme. DISCUSSION: It has been concluded that food allergies affect maternal health extensively, especially in the psychosocial field, and that it affects family relationships, the time that mothers spare for themselves, and physical and spiritual health. APPLICATION TO PRACTICE: The findings will be a guide for improving the quality of life of mothers followed up with food allergies and for the care and counseling support to be provided to mothers.

Histopathological Findings in Turkish Patients Undergoing Sleeve Gastrectomy: Is Histopathologic Examination of Sleeve Gastrectomy Specimens Clinically Important?

PURPOSE: Sleeve gastrectomy (SG) is a widely used surgical method in the treatment of obesity. This study aimed to reveal the histopathological changes in SG materials and to investigate the prevalence of clinically important lesions requiring follow-up. MATERIALS AND METHODS: Three hundred five patients' data who underwent SG were analyzed. Cases were divided into three groups as normal, chronic inactive gastritis (CIG), and chronic active gastritis (CAG). Age, gender, and body mass index (BMI) of the three groups and the differences in the gastritis parameters of CIG and CAG groups were compared. RESULTS: Thirty-three patients (10.8%) were in the normal group, 145 (47.5%) were in the CIG group, and 127 (41.6%) were in the CAG group. Preoperative endoscopic examination was performed in all cases, but Helicobacter pylori (HP) treatment was not applied. HP were detected in 39.3%, atrophy in 3.9%, intestinal metaplasia (IM) in 4.9%, and lymphoid follicle (LF) in 30% of the cases. Inflammation, atrophy, IM, LF, and HP were significantly higher in the CAG group. The proton pump inhibitor (PPI)-related changes were seen in 20 cases and it was more frequent in the CIG group. Intramucosal signet ring cell carcinoma was detected in 1 case. Endocrine cell hyperplasia and dysplasia were present in 7 cases with CAG. Multiple grade 1 neuroendocrine tumors were detected in just 1 case. CONCLUSION: In our SG specimens, HP and clinically important lesions were significantly higher in the CAG group. Pathological examination should be carefully done as the lesions detected in SG specimens can change patient management.

Expression of cytotoxic T lymphocyte-associated antigen 4, CD44, and E-cadherin in the microenvironment of breast carcinomas.

OBJECTIVE: The expression of cytotoxic T lymphocyte-associated antigen 4, E-cadherin, and CD44 in the area of tumor budding was investigated in breast carcinomas in our study. METHODS: Tumor budding was counted at the invasive margins in 179 breast carcinomas. To understand the microenvironment of tumor budding, we examined the expression status of the immune checkpoint molecules such as cytotoxic T lymphocyte-associated antigen 4, E-cadherin, and CD44. RESULTS: Tumors were separated into low (≤5) and high tumor budding groups (>5) based on the median budding number. Lymphovascular, perineural invasion, and the number of metastatic lymph nodes were significantly higher in high-grade budding tumors (p=0.001, p<0.001, and p=0.019, respectively). Tumor-infiltrating lymphocytes were significantly higher in tumors without tumor buddings (p<0.001). When the number of budding increases by one unit, overall survival decreases by 1.07 times (p=0.013). Also, it increases the risk of progression by 1.06 times (p=0.048). In high tumor budding groups, the cytotoxic T lymphocyte-associated antigen 4 staining percentage of lymphocytes was significantly higher (p=0.026). With each increase in the number of buds, an increase in the percentage of cytotoxic T lymphocyte-associated antigen 4 staining was seen in lymphocytes in the microenvironment of TB (p=0.034). CONCLUSION: Tumor budding could predict poor prognosis in breast carcinomas, and anti-cytotoxic T lymphocyte-associated antigen 4 immunotherapies may be beneficial in patients with high tumor budding tumors.

The prognostic significance of non-lymphoid immune cells of the tumor microenvironment, including neutrophils, eosinophils, and mast cells in breast carcinomas.

BACKGROUND AND OBJECTIVE: The prognostic importance of lymphoid cells in the tumor microenvironment and their effect on treatment response have been demonstrated in many cancer types. However, there are limited studies on non-lymphoid immune cells. Conflicting results have been obtained regarding the effects of these cells on prognosis. MATERIALS AND METHODS: A total of 331 patients who underwent surgery for breast cancer were included. Patients that received neoadjuvant chemotherapy and those with distant metastasis were excluded. CD 15 immunohistochemistry was performed to detect tumor-infiltrating neutrophils (TINs) and eosinophils (TIEs), while Toluidine Blue histochemistry was performed to detect tumor-infiltrating mast cells (TIMs). RESULTS: High TINs were statistically associated with low ER expression (p < 0.001), low PR expression (p = 0.001), high Ki-67 proliferation index (p = 0.008), and HER2/TN molecular subtypes (p = 0.001). High TIEs were associated with low ER expression (p = 0.001), high Ki67 proliferation index (p = 0.005), and HER2/TN molecular subtype (p = 0.002). High TIMs were associated with high PR expression (p = 0.024), low Ki-67 proliferation index (p = 0.003), and high survival rate (p = 0.006). TIMs and TIEs were good prognostic factors for overall survival in Luminal A and Luminal B subtypes, while TINs and TIEs were found to be independent risk factors for disease-free survival. CONCLUSION: The evaluation of components of the tumor microenvironment including TINs, TIEs, and TIMs is easy and practical. High TIMs and TIEs are independent prognostic factors, especially in luminal molecular subtype of invasive breast carcinoma. However, to use this parameter in routine pathology practice, more studies from different centers and standard evaluation are needed.

Weekend warrior exercise model for protection from chronic mild stress­induced depression and ongoing cognitive impairment.

We aim to investigate the role and biological mechanisms of the weekend warrior (WW) exercise model on depression­induced rats in comparison to the continuous exercise (CE) model. Sedentary, WW, and CE rats were subjected to chronic mild stress (CMS) procedure. CMS and exercise protocols continued for six weeks. Anhedonia was evaluated by sucrose preference, depressive behavior by Porsolt, cognitive functions by object recognition and passive avoidance, and anxiety levels by open field and elevated plus maze. After behavioral assessments, brain tissue myeloperoxidase (MPO) activity, malondialdehyde (MDA) levels, superoxide dismutase and catalase activities and GSH content, tumor necrosis factor­α (TNF­α), interleukin­6 (IL­6), IL­1ß, cortisol and brain­derived neurotrophic factor levels and histological damage was assessed. CMS­induced depression­like outcomes with increases in anhedonia and decreases in cognitive measures that are rescued with both exercise models. The increased immobilization time in the Porsolt test was decreased with only WW. Exercise also normalized the suppression of antioxidant capacity and MPO increase induced by CMS in both exercise models. MDA levels also declined with both exercise models. Anxiety­like behavior, cortisol levels, and histological damage scores were exacerbated with depression and improved by both exercise models. TNF­α levels were depleted with both exercise models, and IL­6 only with WW. WW was as protective as CE in CMS­induced depression­like cognitive and behavioral changes via suppressing inflammatory processes and improving antioxidant capacity.

The Effect of Mandala Activity and Technology-Based Breastfeeding Program on Breastfeeding Self-Efficacy and Mother-Infant Attachment of Primiparous Women: A Randomized Controlled Study.

The use of art therapy methods such as mandala is becoming increasingly popular in mother-infant health education and counseling. The aim of the study was to evaluate the effect of a mandala and technology-based breastfeeding program on women's breastfeeding self-efficacy and attachment between mother and infant. This randomized controlled, single-blind, and parallel-group trial design was conducted in foundation university hospital. The study was completed by 66 women and their infants (intervention group: n = 33; control group: n = 33). The women who are at the 32-37th gestational week in the intervention group participated in the mandala and technology-based breastfeeding (including Zoom and WhatsApp platforms) program. They received three education module via WhatsApp. Women in control group received routine care. The Maternal Attachment scale and Breastfeeding Self-efficacy Scale were applied in the first week and second month postpartum. Growth follow-ups of the infants were evaluated in the first week, first month and second month postpartum. The registration number of this study on ClinicalTrials.gov is NCT05199298. In the second month postpartum, it was determined that the women in the intervention group had higher Breastfeeding Self-efficacy and Maternal Attachment scale scores compared to the control group (p < 0.05). Also, the rates of breastfeeding in the intervention group were higher than in the control group. Mandala and technology-based breastfeeding program increased women's breastfeeding self-efficacy and maternal attachment. Health care professionals should make use of technology-based educations to give holistic care in maternal and infant health.

A new practical method of estimating tumoral microenvironment parameters of possible prognostic significance in patients with invasive breast carcinoma: Combined microenvironment score.

BACKGROUND AND OBJECTIVE: In recent years, the tumor microenvironment has become increasingly recognized as an influential factor in breast cancer development and growth. The parameters that form the microenvironment are the tumor stroma ratio and tumor infiltrating lymphocytes. In addition, tumor budding, which shows the ability of the tumor to metastasize, gives information about the progression of the tumor. In this study, the combined microenvironment score (CMS) was determined with these parameters, and the relationship between CMS and prognostic parameters and survival was evaluated. MATERIALS AND METHODS: In our study, tumor stroma ratio, tumor infiltrating lymphocytes, and tumor budding were evaluated in hematoxylin-eosin sections of 419 patients with invasive ductal carcinoma. Patients were scored separately for each of these parameters, and these scores were summed to determine the CMS. The patients were divided into 3 groups according to CMS and the relationship between CMS and prognostic parameters and the survival of the patients was studied. RESULTS: The patients with CMS 3 had higher histological grade and Ki67 proliferation index compared to CMS 1 and 2. Additionally, lymphovascular invasion, axillary lymph node and distant metastasis were more common. Disease-free, and overall survival were significantly shortened in the CMS 3 group. CMS was found as an independent risk factor for DFS (HR: 2.144 (95 % CI: 1.219-3.77) p: 0.008), but not an independent risk factor for OS. CONCLUSION: CMS is a prognostic parameter that can be easily evaluated and does not require extra time and cost. Evaluating the morphological parameters of the microenvironment with a single scoring system will contribute to routine pathology practice and predict patient prognosis.

Does Apoptotic Index Predict the Response to Neoadjuvant Chemotherapy in Patients with Breast Carcinoma?

Objective: Neoadjuvant chemotherapy (NACT) plays a major role in the treatment of patients with locally advanced breast carcinoma. Although most patients have benefited from NACT, the rate of residual tumors is still high after treatment (AT). An increase in apoptosis is expected in tru-cut biopsy (TCB) during treatment or AT as the mechanism of NACT is inducing apoptosis. This study aimed to investigate whether evaluating the apoptotic index (AI) from TCB can predict the response before treatment (TC-BT) and whether there is a correlation between AI and clinicopathologic parameters. Methods: Seventy cases of breast carcinomas were included. The AI was evaluated BT and AT by quantifying the apoptosis. The receiver operating characteristic analysis was performed with overall survival (OS) data, and low and high AI cut-offs were obtained. The relationship between AI and response and clinicopathological parameters was evaluated. Results: A significant relationship was found between low AI in TC-BT and at least partial response (p=0.025), longer OS (p=0.01) and disease-free survival (p=0.01), and progesterone receptor-positive tumors (p=0.03). Her2-negative tumors were more prone to low AI. A significant decline in AI (p=0.001) and Ki67 proliferation index (p<0.001) was observed in resections AT. Conclusions: These data suggested that the AI is a simple and cost-effective tool that may play an important role in determining response, and a low AI in TC-BT may have some value as a predictive marker in breast carcinomas.

Predicting response to neoadjuvant therapy with glucose transporter-1 in breast cancer.

OBJECTIVE: Glucose transporter-1 is a marker involved in energy transport in cancer cells. It has been shown to be a poor prognostic factor in many cancer types, including breast cancer. However, there is no satisfactory parameter predicting treatment in breast cancer patients receiving neoadjuvant therapy. This study investigated the effect of glucose transporter-1 in predicting the treatment response of patients receiving neoadjuvant therapy. METHODS: In this study, glucose transporter-1 immunohistochemistry was applied to tru-cut biopsy of patients who were diagnosed with breast cancer and received neoadjuvant therapy between 2010 and 2021. A built-in scoring system was used to evaluate both the pattern and intensity of glucose transporter-1 immunohistochemistry staining. The relationship between glucose transporter-1 immunohistochemistry staining and other clinicopathological parameters was examined. In addition, the relationship of glucose transporter-1 with response to treatment was investigated. RESULTS: A relationship was found between high glucose transporter-1 expression and other clinicopathological parameters (such as estrogen and progesterone receptor negativity, high Ki-67, triple-negative, and Her2 status). Cases with high glucose transporter-1 expression had either a complete or a partial pathologic response. The result was statistically significant. CONCLUSION: Glucose transporter-1 has the potential to be a biomarker that can be evaluated more objectively as an alternative to Ki-67 labeling index in evaluating the response to treatment in patients receiving neoadjuvant therapy.

High Tumor Infiltrating Lymphocytes Are Associated with Overall Survival and Good Prognostic Parameters in Endometrial Endometrioid Carcinoma Patients.

OBJECTIVE: The mortality incidence of endometrial carcinomas (ECs) has increased in recent years. Therefore, recent studies have focused on the cellular and microenvironmental properties of ECs. Tumor-infiltrating lymphocytes (TILs), a component of the microenvironment, have been found to be associated with the prognosis in many tumors. Although TILs were mostly evaluated by immunohistochemical studies in ECs, in our study, the evaluation was done with a light microscope as a practical approach, and we aimed to determine the prognostic importance of TILs in endometrioid ECs. MATERIAL AND METHOD: 104 patients were included in the study. TILs in the stromal area (sTILs) were evaluated on hematoxylin and eosin (HE) stained-sections at X200 objective. The presence of TILs was evaluated as follows; 0-10% as low, 20-40% as moderate, and 50-90% as intense. Then TILs were grouped as low and high. RESULTS: Tumors with high TILs were more prone to have FIGO (International Federation of Gynecology and Obstetrics) grade 1 tumors, low nuclear grade, early pathological stage, smaller size, no lymphovascular invasion, myometrial invasion below 50%, and no cervical involvement. In the presence of high TILs, the overall survival showed significant increase but no significant correlation was found with disease-free survival. CONCLUSION: Interest in the molecular properties of ECs has increased in recent years. TIL, which can be easily evaluated in HE sections, is an important parameter in patient selection for molecular tests and determining the prognosis of patients.

Tumor Budding is an Independent Prognostic Factor to Predict Overall Survival in Endometrial Endometrioid Carcinoma: A Retrospective Study.

Objective. Tumor budding defined as a tumor cell nest away from the main tumor, has been found to be associated with prognostic parameters in many cancer types. We aimed to investigate the relationship between tumor budding and clinicopathological parameters in endometrioid endometrial carcinomas, as well as its prognostic importance. Materials and Methods. One hundred four patients who underwent surgical resection with diagnosis of endometrioid endometrial carcinomas between June 2011 and May 2020 were included. The area where tumor budding was the most prominent was determined, and tumor budding was counted from hematoxylin and eosin-stained section at one high power field (X 200). By performing ROC analysis, the cut off value was obtained in order to divide the patients into low and high tumor budding groups. Results. The cut off value was determined as 1/0.95 mm2 according to the ROC analysis. Tumor budding was observed in 24 (23%) patients. Tumor budding significantly associated with poor overall survival (P < .001), distant metastasis (P = .001), presence of angiolymphatic invasion (P < .001), lymph node metastasis (P = .024), cervical invasion (P < .001), high FIGO grade (P < .001), large tumor size (P = .004). In multivarate analysis, tumor budding and age were found to be an independent risk factor for overall survival (P = .003, P = .014 respectively). Conclusion. Tumor budding is a significant morphological parameter independent of other prognostic parameters in endometrioid endometrial carcinomas. Standardizing the assesment and scoring of tumor budding, as well as including this entity in routine pathology reports could light the way for ideas in the risk analysis of patients.

Nucleolus assessment in invasive breast carcinoma, an objective parameter for histological grading.

BACKGROUND: The nucleolus has the potential to provide insight into how many types of cancer will progress. In this study, we examined the evaluation of the nucleolus with a microscope in widespread breast cancer tumors and whether this value contributes to tumor grading as an objective clinicopathological parameter. METHODS: In our study, the nucleolus was evaluated retrospectively in resections with a diagnosis of invasive breast carcinoma of the cases between January 2010 and April 2021. In total, the tumor nucleolus of 377 cases of invasive breast carcinoma was evaluated. Nucleolus evaluation was performed with light microscopy using four different modes (modified Helpap method, in 1, 5, and 10 high power fields at 40x magnification). The relationship between nucleolar scores and clinicopathological parameters was examined separately. Regrading was performed by replacing nuclear pleomorphism with the nucleolar score in the classically used histological grading system and utilizing the nucleolus score as the fourth parameter in this grading system. RESULTS: There was no significant correlation between the prognosis of the patients and the nucleolar score. When nuclear pleomorphism and nucleolar score were replaced in the classical grading system, disease-free and overall survival were correlated with the new grading system. In addition, a relationship was found between high nucleolus score and other clinicopathological parameters (such as estrogen receptor negativity, progesterone receptor negativity, high Ki-67, triple negative, and human epidermal growth factor receptor-2 status). DISCUSSION: The presence of nucleolus is associated with disease-free survival and overall survival of patients, and it can be evaluated with a light microscope at no extra cost and time. Therefore, in the classical grading, using it instead of nuclear pleomorphism with low reproducibility among pathologists may provide more objective results in predicting patient prognosis.

Does the number of cell forming tumor budding alter the prognostic value in invasive ductal carcinoma of breast?

BACKGROUND AND OBJECTIVE: The most commonly used definition for tumor budding (TB) is a single or a cell cluster of tumor cells up to 4 cells. However, there are different opinions regarding the number of cell (NOC) forming TB. It has been proven that TB is associated with poor prognostic factors in most tumors. The current study, it was aimed to investigate the prognostic value of NOC forming TB in invasive ductal carcinoma of the breast. MATERIALS AND METHODS: 326 cases with the diagnosis of invasive ductal carcinoma were examined. The NOC forming TB was counted from hematoxylin and eosin stained slide under X200 magnification for each case, and scoring five different TB as 1, ≤ 2, ≤ 3, ≤ 4, ≤ 5, respectively. Receiver operating characteristic (ROC) analysis based on survival was performed for each TB value separately, and the cut-off was determined. RESULTS: All TB values were associated with poor outcome (p < 0.001), presence of distant metastasis (p < 0.001), high Ki67 proliferation index (p < 0.05), advanced stage (p < 0.05), presence of lymphovascular invasion (p < 0.001), and metastatic axillary lymph node (p < 0.001). According to ROC analysis performed to compare the predictiveness of survival, the area under the curve was similar for all TB values. CONCLUSION: TB was associated with poor prognostic parameters, and the prognostic value of TB was not affected by NOC forming TB. The NOC up to 4 cells which have been accepted for colon carcinomas, could also provide practicality in breast carcinomas.

Prognositc Significance of Microcystic Elongated and Fragmanted (MELF) Myometrial Invasion Pattern: A Retrospective Study

Objective: Endometrioid endometrial carcinomas (EEC) are the most commonly diagnosed malignancies of the female genital tract. Myometrial invasion depth is one of the most significant pathological prognostic parameters. Different morphological invasion patterns have been characterized. This study aimed to investigate the prognostic significance of the microcystic elongated and fragmented (MELF) myometrium invasion pattern in patients with EEC and its relationship with other clinicopathological parameters. Methods: This study included 101 patients with EEC in our institution between 2011 and 2020. The MELF pattern was evaluated in hematoxylin-eosin-stained sections. Pan-cytokeratin staining was performed on paraffin-embedded blocks of lymph nodes for cases without lymph node metastasis. Results: The MELF pattern was observed in 29 (29.8%) patients. It was significantly associated with lymphovascular invasion (p<0.001), pathologic stage (p=0.048), infiltrative pattern (p<0.001), and necrosis (p=0.005). No significant correlation was observed between the MELF pattern and overall and disease-free survival rates. Conclusions: The MELF pattern is associated with other prognostic parameters, but its prognostic significance for survival has not been found. If the MELF pattern is observed in the hysterectomy material for cases without lymph node dissection during the first surgery, these patients may need additional surgery or adjuvant therapy due to the high risk of lymphovascular invasion and lymph node metastasis.
