In this paper, we draw from academic capitalism to explore the work lives and experiences of faculty who work in a striving university. Our analysis suggests that faculty members feel pressures induced by academic capitalism, including a lack of space, no time and the sense of constant surveillance. Our work adds to the theoretical as well as empirical discussions concerning striving, academic capitalism and the impacts of both on the academic profession.

This study aimed to evaluate the relationship between MCM-2 and Oncotype DX recurrence score (ODX-RS) and determine an MCM-2 cutoff value in high-risk patients according to TAILORx risk categorization.Methods: Hormone receptor (HR) positive HER-2 negative early-stage breast cancer patients (pT1-2, pN0-N1, M0) who had ODX-RS were included in the study. According to the TAILORx trial, patients were divided into two groups with high (ODX-RS ≥ 26) and low risk (ODX-RS < 26) in terms of ODX-RS. Formalin-fixed-paraffin-embedded tissues of patients were re-evaluated, and 3 μm sections were prepared for MCM-2 immuno-histochemical staining. The relationship between ODX-RS and the percentage of MCM-2 staining was evaluated in two groups. The ROC curve analysis was performed to determine the MCM-2 cut-off value for the TAILORx high-risk group (ODX-RS ≥ 26).Results: The mean MCM-2 value was significantly higher in the high-risk group [(60.2 ± 11.2 vs 34.4 ± 13.8, p < 0.001)]. In the multivariate analysis, MCM-2 (OR: 1.27, 95% CI: 1.08– 1.49, p = 0.003) and progesterone receptor (PR) levels ≤ 10% (OR: 60.9, 95% CI: 4.1– 89.7, p = 0.003) were found to be independent factors indicating a high-risk group. A one-unit increase in MCM-2 level increased the likelihood of being in the high-risk group by 1.27 times. In the ROC curve analysis, the optimal MCM-2 cut-off level was 50 (AUC: 0.921, sensitivity: 86.7%, specificity: 96.0%, p < 0.001).Conclusion: Our study is the first study in the literature to investigate the relationship between ODX-RS and MCM-2 levels in HR-positive HER-2 negative early breast-cancer patients. In this study, MCM-2 was an independent risk factor in identifying high-risk patients according to TAILORx risk classification. MCM 2 cut-off value (50) may help the decision on adjuvant chemotherapy in patients where the Oncotype DX test cannot be performed.Keywords: breast cancer, MCM-2, Oncotype DX recurrence score, TAILORx risk categorization

This study aimed to elucidate the role of psychological factors in caregiver burden among caregivers of stage 4 cancer patients. Data were collected from 328 caregivers of cancer patients, employing the Zarit Care Burden Scale, Depression-Anxiety-Stress Scale (DASS-42), Dysfunctional Attitudes Scale (DAS-A), Ruminative Thought Style Questionnaire (RTSQ), and Coping Orientation to Problems Experienced Inventory (Brief COPE). Males, spouses, and caregivers of patients with a PEG or tracheostomy, or those diagnosed with pancreatic biliary cancer were found to have a significantly higher risk of caregiver burden. Age, sex, caregiver-patient relationship, caregiving duration, patient's catheter status, cancer types, depression and stress severity, rumination, dysfunctional attitudes, and dysfunctional coping strategies explained 69.7% of the variance in Zarit Care Burden Scale scores (F(14,313) = 51.457, p < 0.001), illustrating their significant predictive relationship with caregiver burden. Moderation analysis revealed significant interactions of emotional coping with depression (b = -0.0524, p = 0.0076) and dysfunctional coping with stress on caregiver burden (b = 0.014, p = 0.006). Furthermore, rumination mediated the relationships between caregiver burden, stress, and depression ( p < 0.01). Overall, the results highlight the intricate relationships among caregiver burden, mental health, and coping strategies, suggesting tailored interventions to support caregiver health and quality of care.

Cancer's profound impact on emotional well-being necessitates an exploration into the underlying psychological mechanisms influencing depression and anxiety in patients. In this study, we explored the potential role of self-compassion, alexithymia, and cognitive emotion regulation mechanisms in influencing depressive and anxiety symptoms among cancer patients. A total of 151 stage 4 cancer patients participated. Instruments applied included the Beck Depression Scale (BDS), Beck Anxiety Inventory (BAI), Self-Compassion Scale (SCS), Cognitive Emotion Regulation Scale (CERQ), Toronto Alexithymia Scale (TAS), Visual Analogue Scale (VAS), and Brief Psychological Resilience Scale (BRS). The multivariate analysis utilizing the independent variables-SCS, adaptive and maladaptive CERQ, TAS subscales, BRS, and VAS scores-accounted for 39% of the variance seen in BDI (F (8142) = 11.539, p < 0.001). Notably, SCS, adaptive CERQ, and BRS had a negative predictive impact on BDI. Our findings substantiate a statistically significant partial mediatory role of resilience and cognitive emotion regulation in the association between self-compassion and depression. This research accentuates the central role self-compassion, emotional resilience, and cognitive regulation play in the emotional well-being of individuals diagnosed with cancer. Targeted therapeutic interventions focusing on these dimensions may enhance the psychological health of patients, ultimately improving overall treatment outcomes in the oncological setting.

Purpose: The COVID-19 pandemic may have an important long-term emotional impact on patients with cancer diagnosis, as they are in the high-risk group. We aimed to evaluate the relationship between self-compassion, psychological flexibility, and posttraumatic growth, and to examine whether psychological flexibility may serve as a mediator between self-compassion and posttraumatic growth., Methods: Two hundred fifty-three patients with cancer were included in the study. Sociodemographic and Clinical Features Data Form, Self-Compassion Scale (SCS), Freiburg Mindfulness Inventory (FMI), Acceptance and Action Questionnaire-II (AAQ-II), Cognitive Fusion Questionnaire (CFQ), and Posttraumatic Growth Inventory (PTGI) were applied to all patients., Results: The multivariate analysis with independent variable SCS, FMI, AAQ-II, and CFQ scores explains 49% of the variance in PTGI (F(4,248) = 60,585, p < 0.001). SC and FMI scores were found to have a positive and AAQ-II and CFQ scores a negative predictive effect on PTGI scores. The partial mediational effect of psychological flexibility on the relationship between self-compassion and posttraumatic growth was found to be statistically significant., Conclusion: In traumatic life events such as pandemics, the importance of self-compassion for posttraumatic growth and the mediator role of psychological flexibility in this relationship should be considered in order to manage the treatment process in cancer patients. These patients are more affected by the pandemic due to the nature of their malignancy and the strict protective measures they must follow as members of a high-risk group. The significance of therapies focused on psychological flexibility should be emphasized in comprehensive biopsychosocial approaches for the management of cancer patients., (© 2023.

Aim: This study investigated the effect of neoadjuvant chemotherapy (NAC) on stromal tumor-infiltrating lymphocytes (sTILs) and their treatment response. Materials & methods: 115 patients with pre-NAC core biopsies and post-NAC surgical resection specimens were reviewed. Results: There was no significant change between pre- and post-treatment sTILs. Both pre- and post-NAC sTILs were significantly lower in patients with luminal A subtype. An increase in sTILs was observed in 21 (25.9%) patients after NAC, a decrease in 29 (35.8%) and no change in 31 (38.3%; p = 0.07). Pretreatment sTIL density was independent predictor of pathological complete response in multivariate analyses (odds ratio: 1.025, 95% CI: 1.003-1.047; p = 0.023). Conclusion: High sTIL density in core biopsies was independently related to pathological complete response. In addition, ER appears to be the most crucial factor determining the rate of sTIL.

Next-generation sequencing (NGS) technology is used to evaluate hereditary cancer risks of patients worldwide; however, information concerning the germline multigene mutational spectrum among patients with breast cancer (BC) with consanguineous marriage (CM) is limited. Therefore, this prospective study aimed to determine the molecular characteristics of patients with BC who were tested with multigene hereditary cancer predisposition NGS panel and to show the effect of CM on cancer-related genes. Patients with BC with or without CM and family history (FH) of BC treated in our breast center were selected according to The National Comprehensive Cancer Network (NCCN) criteria for hereditary BC. In these patients, the analysis of a panel of 33 genes involved in hereditary cancer predisposition was performed after genetic counseling by using NGS. The pathogenic variant (PV) and the variant of uncertain significance (VUS) were found to be 15.8 and 47.4%, respectively. PVs were identified in 10/33 genes in 34 patients; 38.2% in BRCA1/2 genes; 6, 24, and 14% in other high, moderate and low-risk genes, respectively. The CM rate was 17.7% among the 215 patients with BC. The PV rate was 13.2% in patients with CM and 16.4% in patients without CM (P=0.80). When PV and VUS were evaluated together, the PV+VUS ratio was significantly higher in patients with CM and FH of BC than patients without CM and FH of BC (88.2 vs. 63.3%, P=0.045). Analysis of multigene panel provided 9.76% additional PVs in moderate/low-risk genes. The PV rate was similar in patients with BC with or without CM. A high PV+VUS ratio in patients with CM and FH of BC suggests that genes whose importance are unknown are likely to be pathogenic genes later., Competing Interests: The authors declare that they have no competing interests., (Copyright: © Ozmen et al.)

The benefit of breast magnetic resonance imaging (MRI) in breast-conserving surgery (BCS) is unclear. Our study compared breast cancer patients with and without preoperative breast MRI and their long-term oncologic outcomes are reported. A total of 1378 BCS cases with early breast cancer between 1996 and 2017 were reviewed. Patients with carcinoma in situ or neoadjuvant treatment or having breast MRI after tumor excision were excluded. Of 1378 patients, 270 (19.5%) had preoperative MRI. There were no significant differences regarding T and N stage and molecular subtypes between the groups. Surgical margins were significantly wider in the breast MRI group. Five-year overall survival (OS) was 96.9% in the MRI group and 94.3% in the control group, and this difference was not significant (p=0.11). Five-year local-regional recurrence-free survival (LRFS) was not significantly different either (98.8% and 96.5%, respectively, p=0.41). When analyses were repeated only for patients with hormone receptor-negative or triple-negative breast cancer, there was still no significant difference in OS, LRFS, or disease-free survival. In conclusion, MRI does not seem necessary in all patients undergoing BCS. New prospective randomized controlled trials are needed to determine appropriate use of preoperative MRI and its effects on oncologic outcomes in early breast cancer patients.

Most reports of Multisystem Inflammatory Syndrome (MIS-C) have come from Europe and North America. The paucity of reports in Africa is in contrast with the demographics of the series in New York, Paris and UK with children of African ancestry accounting for over 40% of all cases of MIS-C. With the global trend of higher prevalence of MIS-C in children of African ancestry, enhanced surveillance and awareness for this syndrome in children with COVID-19 in Africa are therefore important. A case report of a 12-year-old Nigerian girl with MIS-C is presented in line with the WHO global surveillance especially in areas were MIS-C is considered a rarity. This case report stimulates a call for vigilance and expanded effort at surveillance to promote early recognition and diagnosis of MIS-C in Nigeria and Africa. The favourable outcome and experience from this case will create awareness, expand knowledge, and support clinicians in Nigeria and the African continent in their approach to other potential cases., (Copyright © 2021 The Author(s).

Purpose: The purpose of this study was to compare the multifocal (MF)/multicentric (MC) breast cancers with unifocal (UF) breast cancers in terms of tumour characteristics, treatment methods, loco-regional recurrence and survival rates., Methods: Patients who were treated with a diagnosis of early-stage breast cancer (stage I,II) and had regular follow-up were included in the study. MF tumours were defined as having more than one tumour focus in the same quadrant, whereas MC tumours refered to the presence of more than one tumour focus in different quadrants., Results: In total, 1865 patients with invasive breast cancer were evaluated, 1493 (80.1%) of whom had UF cancer, 330 (17.7%) had MF cancer, and 42 (2.3%) had MC cancer. After comparing the groups with each other, it was seen that MF and MC breast cancers occurred more often at early ages and that lymph node invasion (LNI) was greater. No differences were seen between the 3 groups in terms of local recurrence-free survival (RFS) and overall survival (OS) rates . In multivariate analysis, it was found that MF and MC tumours had no impact on local recurrence and OS. In multivariate analysis, it was understood that HER2 positivity and triple-negative breast cancer (TNBC) had an impact on local recurrence, and age, lymphovascular invasion (LVI), T3 tumour, lymph node positivity and TNBC subtype had an impact on OS., Conclusion: Although MC and MF tumours show aggressive features such as high lymph node positivity and LVI, they have similar loco-regional recurrence and survival rates to UF tumours.

Purpose: The latissimus dorsi muscle has long been used in breast cancer (BC) patients for reconstruction. This study aimed to compare early stage BC patients who had partial mastectomy (PM) with mini latissimus dorsi flap (MLDF) and subcutaneous mastectomy with implant (MI) with respect to quality of life (QoL), cosmetic outcome (CO), and survival rates., Patients and Methods: The data of patients who underwent PM + MLDF (Group 1) and M + I (Group 2) between January 2010 and January 2018 were evaluated. Both groups were compared in terms of demographics, clinical and pathological characteristics, surgical morbidity, survival, quality of life, and cosmetic results. The EORTC-QLQ C30 and EORTC-QLO BR23 questionnaires and the Japanese Breast Cancer Society (JBCS) Cosmetic Evaluation Scale were used to assess the quality of life and the cosmetic outcome, respectively., Results: A total of 317 patients were included in the study, 242 (76.3%) of them in group 1 and 75 (23.6%) of them in group 2. Median follow-up time was 56 (14-116) months. There were no differences identified between the groups in terms of tumor histology, hormonal receptors and HER-2 positivity, surgical morbidity, and 5-year overall and disease-free survival. Group 2 patients were significantly younger than group 1 (p = 0.003). The multifocality/multicentricity rate was higher in group 2 (p ≤ 0.001), whereas tumor size (p = 0.009), body mass index (BMI, p = 0.006), histological grade (p ≤ 0.001), lymph node positivity (p = 0.002), axillary lymph node dissection (ALND) rate (p = 0.005), and presence of lympho-vascular invasion (LVI, p = 0.013) were significantly higher in group 1. When the quality of life was assessed by using the EORTC QLQ C30 and BR23 questionnaires, it was seen that the body image perception (p < 0.001) and nausea/vomiting score (p = 0.024) were significantly better in PM + MLDF group whereas physical function score was significantly better in M + I group (p = 0.012). When both groups were examined in terms of cosmesis with JBCS Cosmetic Evaluation Scale, good cosmetic evaluation score was significantly higher in patients in MLDF group (p = 0.01)., Discussion: The results of this study indicate that in comparison to M + I procedure, the PM + MLDF procedure provides significantly superior results in terms of body image and cosmetic result with similar morbidity and oncologic outcomes. In selected patients with small breasts and a high tumor/breast ratio, PM + MLDF may be an alternative to subcutaneous mastectomy and implant.

Background: Early detection of lymphedema gives an opportunity for effective and successful treatment of lymphedema. However, the current diagnosis methods, except the bioimpedance analysis, perometry, and indocyanine green lymphography, have limitations in detecting early stage lymphedema. Sonoelastography is a diagnostic ultrasound technique that provides an opportunity to estimate soft tissue stiffness. Shear wave elastography (SWE) is a brand new elastography technique. Unlike strain elastography, this method is conducted automatically, that is, independently of user's manual tissue compression. The aim of this study is to establish the role of sonoelastography in diagnosis and staging of lymphedema by using the SWE technique in lymphedema patients. Methods and Results: A total of 36 female lymphedema patients were included in the study. There was no significant difference between patients with stages 1 ( n  = 17) and 2 ( n  = 19) lymphedema in terms of age, duration after surgery, and body mass index ( p  > 0.05). But, differences in terms of circumference measurements for forearm and arm, L-DEX values, and duration of lymphedema were found to be statistically significant ( p  = 0.002-0.000-0.000-0.001). Elastography measurements between normal forearm and forearm with lymphedema showed a statistically significant difference ( p  = 0.012). Correlation was found between circumference measurements and elastography values of forearms ( p  = 0.004, r  = 0.471) and L-DEX scores and elastography measurements ( p  = 0.041, r  = 0.352). When circumferential measurements of the forearms with lymphedema were compared with those with normal forearms, stage 1 patients showed no significant difference ( p  = 0.850), whereas a significant difference was detected in stage 2 patients ( p  = 0.003). Conclusion: SWE should be a useful tool in diagnosis and distinguishing early and late stages of lymphedema.

Purpose: The objective of this study was to assess the demographic, pathologic and survival characteristics of patients who were diagnosed as having bilateral breast cancer., Methods: A review was conducted of the records pertaining to patients who presented to our clinic and were diagnosed as having breast cancer. Any second cancer diagnosed within 12 months of initial diagnosis was defined as synchronous bilateral breast cancer. Assessment included treatments administered to the patients and survival rates, as well as their demographic, reproductive and pathologic features., Results: The total number of patients who were diagnosed as having bilateral breast cancer in the context of the present study was 99. Among the patients with synchronous breast cancer, the median age at the time of initial diagnosis was found as 57 years. The median age of the discovery of first tumor among the patients with metachronous tumor was 52 years and the median age of second tumor detection was 59 years. Family history in metachronous tumor was significantly greater (p=0.041). The median time of metachronous cancer incidence was 96 months. The length of disease-free period among the patients with synchronous tumor was 126.3 months, whereas it was 243.7 months in those with metachronous tumor (p=0.041)., Conclusion: The incidence rate of synchronous breast tumors has been rising thanks to growing awareness and the leading-edge imaging methods. The fact that the second tumor developed after more than 5 years among the patients with metachronous cancer gave rise to the increased rate of survival.

Objectives: In this study, they investigated whether mean thrombocyte volume (MPV) and MPV/platelet count ratio have a prognostic significance in advanced NSCLC or not., Methods: A total of 496 NSCLC patients at stage IIIB/IV and did not meet exclusion criteria were included in the study. The demographic features (age, gender, smoking habit), clinical characteristics (performance status, weight loss, disease stage, first-line treatment regimen), laboratory tests (levels of hemoglobin, lactate dehydrogenase and calcium as well as MPV, MPV/platelet count ratio and counts of white blood cell, platelet), and histological features (histologic type, tumor grade) were recorded., Results: The MPV levels of all patients were determined as 10.2 {plus minus} 3.4 (range, 6.4-14.1 fL). With ROC curve analysis, the MPV/PC ratio was associated with a sensitivity of 67.8% and a specificity of 84.8% at a cutoff value of 0.47424 for presence of brain metastasis at the time of diagnosis. Univariate analysis showed that OS was significantly shorter in the group with an increased MPV level than in the other group (median OS time 6.8 months vs. 11.5 months, log-rank, P = .032). Multivariate analysis confirmed that an increased MPV level was an independent poor prognostic factor for OS (HR: 1.704, 95% CI: 1.274-3.415, P = .014)., Conclusions: Unlike results of previous studies, the study showed that increased MPV was an important prognostic factor in patients with NSCLC. Hence, an increased MPV level may be used as a prognostic biomarker to estimate for poor overall survival in patients with NSCLC., (© 2017 John Wiley & Sons Ltd.)

Background: Prolongation of survival in patients with breast cancer due to early diagnosis and modern methods of treatment has turned the attention on lymphedema, which is the most important morbidity secondary to the treatment of the disease. Determination of lymphedema and related risk factors in patients before a surgical intervention may provide protection for patients and early treatment. The aim of this study was to determine the presence of lymphedema before surgery by bioimpedance analysis in patients with breast cancer and to establish risk factors associated with lymphedema., Patients and Methods: A total of 277 patients who were diagnosed as having breast cancer, were planned to undergo a surgical intervention, and had no clinical lymphedema were included in the study. The presence of lymphedema was evaluated with clinical examination, measurement of arm circumference, and bioimpedance analysis., Results: Lymphedema was found in 59 (21.3%) patients with no detected differences in arm circumferences. A significant relationship was found between the presence of lymphedema and body mass index (BMI), number of positive lymph nodes, and capsule invasion of the tumor (p = 0.001, p = 0.003, p = 0.002, respectively). Multiple regression analysis revealed that BMI and the number of positive lymph nodes were independent variables (p = 0.024, p = 0.002). ROC curve analysis resulted in an increased risk of preoperative lymphedema when the number of positive lymph nodes was ≥8. Correlation analysis revealed a positive correlation between the number of positive lymph nodes and L-dex score (p = 0.001, r = 0.219)., Conclusion: Preoperative bioimpedance analysis demonstrated that ∼1/5 of the patients had subclinical lymphedema. Preoperative subclinical lymphedema is associated with obesity and the number of positive lymph nodes, and thus, treatment of the axilla in patients who are preoperatively detected to have subclinical lymphedema should be revised.

Aim: To evaluate the efficacy and tolerability of neoadjuvant hyperfractionated accelerated radiotherapy (HART) and concurrent chemotherapy in patients with locally advanced infraperitoneal rectal cancer., Methods: A total of 30 patients with histopathologically confirmed T2-3/N0+ infraperitoneal adenocarcinoma of rectum cancer patients received preoperative 42 Gy/1.5 Gy/18 days/bid radiotherapy and continuous infusion of 5-fluorouracil (325 mg/m 2 ). All patients were operated 4-8 wk after neoadjuvant concomitant therapy., Results: In the early phase of treatment, 6 patients had grade III-IV gastrointestinal toxicity, 2 patients had grade III-IV hematologic toxicity, and 1 patient had grade V toxicity due to postoperative sepsis during chemotherapy. Only 1 patient had radiotherapy-related late side effects, i.e ., grade IV tenesmus. Complete pathological response was achieved in 6 patients (21%), while near-complete pathological response was obtained in 9 (31%). After a median follow-up period of 60 mo, the local tumor control rate was 96.6%. In 13 patients, distant metastasis occurred. Disease-free survival rates at 2 and 5 years were 63.3% and 53%, and corresponding overall survival rates were 70% and 53.1%, respectively., Conclusion: Although it has excellent local control and complete pathological response rates, neoadjuvant HART concurrent chemotherapy appears to not be a feasible treatment regimen in locally advanced rectal cancer, having high perioperative complication and intolerable side effects. Effects of reduced 5-fluorouracil dose or omission of chemotherapy with the aim of reducing toxicity may be examined in further studies., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest, financial or otherwise.

Objectives: The role of tobacco in the pathogenesis of lung cancer (LC) has been clearly established. Based on the epidemiological evidence that smoking may influence LC progression, we investigated the idea that smoking behavior could be associated with overall survival (OS) in this group of patients., Methods: A total of 351 patients with LC (311 men and 40 women) were reviewed. Smoking status was assessed as tobacco users or non-users. To calculate pack-years of smoking, the average of number of cigarettes smoked per day was divided by 20 to give packs per day, and then multiplied by the total number of years of smoking. OS was the main outcome measure., Results: The mean follow-up was 3.3 ± 1.2 years. Kaplan-Meier plots of OS by use of tobacco revealed significant differences by smoking status (log-rank = 5.44, P < 0.01), indicating a reduced survival rate in tobacco users. The effect on OS of the amount of cigarette smoking was also evident when we subdivided the former and current smokers into ≤7 (mean value) pack-years and >7 pack-years groups (log-rank = 4.27, P < 0.05). After adjusting for all potential confounders, tobacco smoking retained its independent prognostic significance for OS (hazard ratio = 1.53, 95% confidence interval = 1.19-2.17, P = 0.02)., Conclusions: Our data indicate that cigarette smoking is significantly associated with a poor prognosis among patients diagnosed with LC in a dose-dependent manner., (© 2015 John Wiley & Sons Ltd.)
