RESUMO
OBJECTIVE: To determine the predictive factors for the pathological complete response (pCR) in patients with non-ductal invasive breast cancer (ND-BC) receiving neoadjuvant chemotherapy. STUDY DESIGN: Observational study. Place and Duration of the Study: Departments of Medical Oncology, Tekirdag Namik Kemal University, Sirnak State Hospital, Aydin Adnan Menderes University, Marmara University, Bakirkoy Sadi Konuk Hospital, Basaksehir Cam and Sakura Hospital, Sakarya University, Balikesir Ataturk Hospital, Turkiye, from April 2016 to December 2022. METHODOLOGY: A total of 222 non-metastatic breast cancer patients who received neoadjuvant chemotherapy were included in this retrospective multicentric study. The clinicopathologic data were obtained from the hospitals' electronic-record-system. The logistic regression models were used to identify predictive factors for pCR. RESULTS: One hundred and twenty-six patients (56.8%) had invasive lobular carcinoma and 28 patients (12.6%) had signet ring cell/mucinous carcinoma. A total of 45 patients (20.3%) achieved pCR. The pCR rate was 14.3% for lobular carcinoma and 17.9% for signet ring cell/mucinous carcinoma. The univariate analysis showed that estrogen receptor-negative tumours (p = 0.017), high Ki-67 (p = 0.008), high histologic grade (p<0.001), HER2+ expression (p<0.001), and non-lobular histologic type (p = 0.012) were predictive factors for pCR. The multivariate model revealed that HER2 expression (p<0.001) and Ki-67 (p = 0.005) were independent predictors. CONCLUSION: Neoadjuvant chemotherapy demonstrated effectiveness in ND-BC patients, leading to favourable pCR rates and enabling breast-conserving surgery. Predictive markers for pCR varied depending on histologic types, with HER2 expression, ER status, Ki-67, and histologic grade showing significance in non-ductal subtypes, while HER2 status alone was predictive in lobular carcinoma.

INTRODUCTION: In this study, the toxicities and management of palbociclib and ribociclib in older patients (≥65 years) with metastatic breast cancer patients were investigated. MATERIALS AND METHODS: Among older patients receiving palbociclib and ribociclib, Geriatric 8 (G8) and Groningen Frailty Index were used to evaluate frailty status. Dose modifications, drug withdrawal and other serious adverse events (SAEs) were recorded and analyzed according to baseline patient characteristics. RESULTS: A total of 160 patients from 28 centers in Turkey were included (palbociclib = 76, ribociclib = 84). Forty-three patients were ≥ 75 years of age. The most common cause of first dose modification was neutropenia for both drugs (97% palbociclib, 69% ribociclib). Liver function tests elevation (10%) and renal function impairment (6%) were also causes for ribociclib dose modification. Drug withdrawal rate was 3.9% for palbociclib and 6% for ribociclib. SAEs were seen in 11.8% of those taking palbociclib and 15.5% of those on riboclib. An ECOG performance status of ≥2 and being older than 75 years were associated with dose reductions. Severe neutropenia was more common in patients with non-bone-only metastatic disease, those receiving treatment third-line therapy or higher, coexistance of non-neutropenic hematological side effects (for ribociclib). Neutropenia was less common among patients with obesity. DISCUSSION: Our results show that it can be reasonable to start palbociclib and ribociclib at reduced dose in patients aged ≥75 years and/or with an ECOG performance status ≥2.

In the present study, we aimed to assess the association between the serum survivin level and overall survival and treatment response rates in metastatic pancreatic cancer (MPC). Serum samples were prospectively collected from 41 patients with newly diagnosed MPC patients and 41 healthy individuals (control group) to assess the survivin levels. The median survivin level was 136.2 ng/mL in patients with MPC and 52 ng/mL in healthy individuals (P = .028). Patients were divided into low- and high-survivin groups according to the baseline median survivin level. Patients with a high serum survivin level compared with a low serum survivin level had shorter median progression-free survival (2.39 vs 7.06 months; P = .008, respectively) and overall survival (3.74 vs 9.52 months; P = .026, respectively). Patients with higher serum survivin levels had significantly worse response rates (P = .007). The baseline high level of serum survivin in patients with MPC may be associated with treatment resistance and poor prognosis. A confirmation will be needed for these results in future large multicenter prospective studies.

Introduction: Crizotinib is a tyrosine kinase inhibitor used in patients with non-small cell lung cancer, and there are uncertainties about its effect on kidney function. In this study, it was aimed to document the possible adverse effect of the drug on kidney functions. Materials and Methods: The estimated glomerular filtration rates (eGFRs) of the patients were calculated by creatinine-based Chronic Kidney Disease Epidemiology Collaboration and compared by months using the paired samples t-test. Kaplan-Meier survival method was used for progression-free survival and overall survival (OS) analysis. Results: Twenty-six patients who received crizotinib were included in the study, and the median progression-free survival time with crizotinib was 14.2 months and the median OS time was 27.4 months. There was a significant reduction of eGFR after the 1st month of crizotinib treatment when compared to the rate before treatment initiation (P < 0.001). The eGFR values at the end of the 1st month and the 2nd month of treatment and the 2nd and 3rd months of treatment were statistically similar (P = 0.086, P = 0.663; respectively). This decrease in eGFR values was reversible, and there was no difference detected between pretreatment and posttreatment discontinuation (P = 0.100). Conclusion: A reversible decrease in renal functions was detected in patients using crizotinib. When the literature data are examined, it is thought that the reason for this decrease may be related to the increase in renal inflammation or a pseudo decrease due to the decrease in creatinine excretion. When evaluating renal functions in these patients, using noncreatine-based (iothalamate, etc.) calculations can give more accurate results.

AIM: The primary aim of this study was to compare tamoxifen versus aromatase inhibitors (AI) in terms of urinary incontinence (UI) in premenopausal female patients receiving adjuvant hormone therapy for breast cancer. A secondary aim was to investigate the prevalence and the affecting factors of UI. METHODS: This study was designed as a multicenter, cross-sectional that included consecutive premenopausal breast cancer patients ≤50 years of age receiving tamoxifen (with/without LHRHa) or AI (with LHRHa) for at least 6 months, between June 2021 and September 2022. Patients with urinary incontinence before hormone treatments and metastatic patients were excluded from the study. Turkish validation of The International Consultation on Incontinence Modular Questionnaire Urinary Incontinence Short Form (ICIQ UI-SF) was used to determine the UI. Using logistic regression methods, we analyzed potential predictive factors for UI. RESULTS: A total of 206 breast cancer patients were included in this study. A total of 120 (58.2%) patients were receiving tamoxifen plus LHRHa, 40 (19.4%) patients were receiving aromatase inhibitor plus LHRHa, and 46 (22.3%) patients were receiving tamoxifen only. In this study, the prevalence of urinary incontinence was found to be 35.9% (n:74). 41% of the patients receiving tamoxifen and 15.0% of those receiving aromatase inhibitors had complaints of urinary incontinence. There was a statistically significant difference between patients receiving tamoxifen or aromatase inhibitor in terms of urinary incontinence (p=0.001). In the univariate analysis established to predict UI, parity (≥2 vs <2) (OR = 3.23, 95% CI: 1.62-6.46, p= 0.001), tamoxifen (vs AI) (OR = 3.97, 95% CI: 1.58-9.98, p= 0.003), age ( ≥40 vs. <40) (OR = 2.80, 95% CI: 1.37-5.71, p= 0.005), vaginal deliveries (≥2 vs. <2) (OR = 3.28, 95% CI: 1.44-7.46, p= 0.005), hypertension (OR = 3.59, 95% CI: 1.43-9.02, p= 0.007), diuretic use (OR = 2.55, 95% CI: 1.09-5.95, p= 0.031) ), and body mass index (≥25 vs <25) (OR = 1.94, 95% CI: 1.05-3.63), p= 0.034) was found to be predictive. Tamoxifen (OR = 4.71, 95% CI: 1.77-12.56, p= 0.002), hypertension (OR = 3.48, 95% CI: 1.27-9.52, p= 0.015), and age (OR = 2.35, 95% CI: 1.10-5.02, p= 0.027) remained independent predictors for incontinence in multivariate analyses. CONCLUSION: We found that tamoxifen had increased the risk of urinary incontinence compared to aromatase inhibitors in patients receiving hormone therapy for breast cancer. In addition, we showed that age and hypertension were also independent predictors for UI. In the context of quality of life, we recommend close follow-up of these patients, as drug adherence may be affected in the event of urinary incontinence.

OBJECTIVE: To predict short and long-term mortality in patients who were admitted to the emergency department and then hospitalised unplanned in medical oncology-ward. STUDY DESIGN: An observational study. Place and Duration of the Study: Department of Medical Oncology, Tekirdag Namik Kemal University Hospital, Tekirdag, Turkiye, from May 2021 to May 2022. METHODOLOGY: Consecutive patients admitted to the emergency department with unplanned hospitalisation in the oncology ward, were included. Patients receiving treatment with the curative intent, patients hospitalised for febrile neutropenia, and terminally ill patients requiring intensive care unit follow-up at admission were excluded from the study. Univariate and multivariate logistic regression analyses were used to identify predictive factors for short and long-term mortality-dependent variables. RESULTS: This study included 253 advanced cancer patients. The number of patients who died in the ward within 10 days (short-term mortality) was 28 (11.1%). Ninety patients (35.6%) died afterwards anytime in the ward during the study (long-term mortality). In the multivariate analysis established for short-term mortality, higher ALT (OR = 6.75, 95% CI: 2.09 - 21.85, p=0.001), rapid deterioration in performance status (OR = 5.49, 95% CI: 1.81-16.67, p=0.003), higher CRP (OR = 5.86, 95% CI: 1.20-28.53, p=0.029), higher procalcitonin (OR = 7.94, 95% CI: 0.99 - 63.82, p=0.051), and higher lactate (OR = 2.47, 95% CI: 0.94-6.51, p=0.067) showed significant predictive features. CONCLUSION: The decision of whether to continue treatment or not is challenging in cancer patients who require unplanned hospitalisation while receiving palliative systemic therapy. New mortality estimation models can be used in making the transition from life-long to palliative treatments. KEY WORD: Mortality prediction, Hospitalisation, Estimation of survival, Chemotherapy.

OBJECTIVE: The aim of this study was to investigate the predictive importance of the previously validated log(ER)*log(PgR)/Ki-67 predictive model in a larger patient population. METHODS: Patients with hormone receptor positive/HER-2 negative and clinical node positive before chemotherapy were included. Log(ER)*log(PgR)/Ki-67 values of the patients were determined, and the ideal cutoff value was calculated using a receiver operating characteristic curve analysis. It was analyzed with a logistic regression model along with other clinical and pathological characteristics. RESULTS: A total of 181 patients were included in the study. The ideal cutoff value for pathological response was 0.12 (area under the curve=0.585, p=0.032). In the univariate analysis, no statistical correlation was observed between luminal subtype (p=0.294), histological type (p=0.238), clinical t-stage (p=0.927), progesterone receptor level (p=0.261), Ki-67 cutoff value (p=0.425), and pathological complete response. There was a positive relationship between numerical increase in age and residual disease. As the grade of the patients increased, the probability of residual disease decreased. Patients with log(ER)*log(PgR)/Ki-67 above 0.12 had an approximately threefold increased risk of residual disease when compared to patients with 0.12 and below (odds ratio: 3.17, 95% confidence interval: 1.48-6.75, p=0.003). When age, grade, and logarithmic formula were assessed together, the logarithmic formula maintained its statistical significance (odds ratio: 2.47, 95% confidence interval: 1.07-5.69, p=0.034). CONCLUSION: In hormone receptor-positive breast cancer patients receiving neoadjuvant chemotherapy, the logarithmic model has been shown in a larger patient population to be an inexpensive, easy, and rapidly applicable predictive marker that can be used to predict response.

OBJECTIVE: To evaluate the strongest prognostic factors in advanced gastric cancer. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Medical Oncology, Tekirdag Namik Kemal University, Tekirdag, Turkey, between March 2012 and April 2022. METHODOLOGY: Adult patients with metastatic cancer who had completed at least two months of chemotherapy, without any other comorbidity were included. Using Kaplan-Meier methodology and Cox regression methods, potential prognostic factors were analysed for overall survival. Two different models were created for multivariate analysis by using statistically significant factors in univariate analysis. RESULTS: The median overall survival in 216 patients was 7.8 months. The univariate analysis showed that body-mass index, performance status, liver metastasis, albumin, gamma-glutamyl transferase, carcinoembryonic antigen, carbohydrate antigen (CA 19-9), neutrophil-lymphocyte ratio (NLR), systemic immune-inflammation index, albumin-to-alkaline phosphatase ratio, sodium-globulin ratio (SGR) prognostic nutritional index (PNI), albumin-bilirubin ratio, and albumin-globulin ratio were associated with survival. In Model 1, which included only laboratory indices, multivariate analyses revealed that NLR (p=0.001), SGR (p=0.025), and PNI (p=0.032) were prognostic for overall survival. In Model 2, established with all parameters, NLR (p=0.003), albumin (p=0.003), performance status (p<0.001), and CA 19-9 (p<0.001) were found to be independent prognostic factors. CONCLUSION: Pretreatment NLR, SGR, PNI, albumin, performance status, and CA 19-9 are strong prognostic factors in patients with advanced gastric cancer. These prognostic factors, which are easily accessible in clinical practice, may be utilised as useful tools for clinicians.

Aim of the study: Although early diagnosis of breast cancer (BC) is often associated with a good prognosis, there is currently no biomarker with high sensitivity serving this purpose. B7H3, a recently identified member of the B7 family, appears to inhibit antitumor immunity. We investigated the soluble B7H3 (sB7H3) level in BC and its relationship with clinicopathological variables and stromal tumor-infiltrating lymphocytes (sTILs). Material and methods: The study, which was designed as a cross-sectional trial between January 2020 and September 2021, included 93 BC patients, 20 patients with benign breast disease (BBD) and 14 healthy volunteers as the control group. Serum sB7H3 levels were measured using the ELISA (enzyme-linked immunosorbent assay) method and sTILs were measured by immunohistochemistry using Tru-cut biopsy materials. Results: sB7H3 levels in BC patients were significantly higher than those in patients with BBD and healthy volunteers. Receiver operating characteristic curve analysis results showed that sB7H3 level may be a potential biomarker for distinguishing patients with BC from those with BBD (AUC: 0.807; sensitivity: 0.786; specificity: 0.706) and from healthy volunteers (AUC: 0.731; sensitivity: 0.700; specificity: 0.692). Conclusions: To the best of our knowledge, the present study is the first to investigate the relationship between sB7H3 and disease parameters in BC. We found that sB7H3 may be a clinically practical and meaningful biomarker in differentiating BC from BBD. In order to evaluate the relationship of B7H3 with clinical variables in BC, and especially with sTILs, tissue-based studies with higher numbers of patients are needed.
RESUMO
OBJECTIVE: To compare seroconversion for SARS-CoV-2 receptor-binding domain (RBD) specific IgG positivity against two doses of the CoronaVac vaccine in breast and lung cancer patients receiving systemic therapy, to determine the factors affecting seropositivity, and to observe long-term results up to a secondary booster vaccine. RESULTS: The analysis included 201 cancer patients (99 breasts, 102 lungs; median age: 59 years (range: 28-92), 42.3 % men) and 97 controls (median age: 62 years (range: 24-87), 38.1 % men). The seropositivity rate for RBD IgG after 2 doses of vaccine in the cancer group was 81.6 % (n=164) and 93.8 % (n=91) in the control group (p=0.005). The median IgG titer of cancer patients was significantly lower than in the control group (338 (IQR, 95-933) AU/mL vs 676 (IQR, 389-1270) AU/mL; p<0.001). Multivariate analysis of all the patients determined that having cancer (OR: 0.303, 95%CI: 0.123-0.750, p=0.010) and being over 60 years of age (OR: 0.447, 95%CI: 0.218-0.917, p=0.028) was associated with a reduced vaccine response. A subgroup analysis of cancer patients revealed that seroconversion was lower in men than in women (75.3 % vs 86.2 %, p=0.049) and lower in ≥60 patients than in <60 patients (75.9 % vs 89.4 %, p=0.014). DISCUSSION AND CONCLUSION: Cancer patients receiving an active systemic therapy with two doses of the CoronaVac vaccine had a lower antibody response than the non-cancer population, and deaths due to COVID-19 may occur in these patients despite the vaccine. Therefore, extensive protective measures should be taken to protect against COVID-19 in cancer patients aged 60 years and older, who have received two doses of the CoronaVac vaccine (Tab. 4, Fig. 4, Ref. 27).

BACKGROUND: In older patients with cancer, it is very important to choose the appropriate treatment because they are at high risk for chemotherapy toxicity. Our study investigated characteristics of Cancer and Aging Research Group (CARG), Geriatric 8 (G8), and Vulnerable Elders Survey (VES-13) screening tools for predicting chemotherapy-related toxicity (CRT) prospectively. MATERIALS AND METHODS: 208 patients aged ≥65 years old for whom chemotherapy was planned to treat non-haematological cancer between February 2021-September 2021 were included in the study. The CARG, G8, and VES-13 toxicity tools were completed by the oncologist through face-to-face interviews before starting the first chemotherapy treatment. CRTs during chemotherapy were evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events v4.03. Logistic regression models, the area under the receiver operating characteristic curve (ROC-AUC), and correlation analyses were used for comparing questionnaires. RESULTS: Median age was 70.4 (range 65-86) years. Of the participants, 103 (49.5%) participants experienced grade 3-5 CRT (32.2% haematological, 28.4% non-haematological) during chemotherapy. ROC-AUC value of CARG was determined as 0.827 (95% CI [confidence interval]: 0.77-0.88, p < 0.001), it was determined as 0.744 (95% CI: 0.68-0.81, p < 0.001) for G8 and 0.726 (95% CI: 0.66-0.80, p < 0.001) for VES-13. In the univariate regression analysis, CARG (OR [odds ratio] = 13.57, 95% CI: 6.0-30.72, p < 0.001), G8 (OR = 3.19, 95% CI: 1.62-6.29, p = 0.001), and VES-13 (OR = 9.5, 95% CI: 5.01-17.89, p < 0.001) were found to be predictive for CRT. The multivariate analysis (included stage, Eastern Cooperative Oncology Group [ECOG] performance status, presence of comorbid disease, platinum-based treatment regimen, taxane-based treatment regimen, CARG, VES-13, G8) showed that CARG (OR = 12.08, 95% CI: 5.11-28.56, p < 0.001), VES-13 (OR = 10.06, 95% CI: 4.92-22.98, p < 0.001), and G8 (OR = 2.20, 95% CI: 1.04-4.69, p = 0.040) screening tools were strong predictors for CRT. The CARG and VES-13 questionnaires were predictive for reducing the initial treatment dose (p = 0.004, p = 0.004, respectively), interruption of treatment (p < 0.001, p < 0.001, respectively), discontinuing treatment (p = 0.002, p = 0.002, respectively), and unexpected hospitalisation (p = 0.012, p = 0.003, respectively). CONCLUSIONS: We showed that all three CARG, G8, and VES-13 questionnaires are helpful tools in the decision-making process for ideal chemotherapy to predict severe CRT; however, CARG and VES-13 questionnaires appear more useful in daily oncology practice than the G8 questionnaire.

Sentinel lymph node dissection (SLND) is a reliable method that provides axillary staging in clinical node-negative (cN0) breast cancer patients before neoadjuvant chemotherapy (NACT). However, it is not a standard method on its own due to the high false-negative rates (FNR) reported in initially clinical node-positive patients (cN1-cN3). The contribution of magnetic resonance imaging (MRI) to SLND after chemotherapy is not well understood. In our study, we aimed to investigate the contribution of post-NACT MRI to SLND in breast cancer patients receiving NACT. Between January 2014 and December 2020, patients who had MRI images including the axilla after NACT and had axillary lymph nodes evaluation performed simultaneously with SLND were included in the study. MRI images of all patients were re-evaluated by 2 experienced clinicians. MRI and SLND results were analyzed to detect axillary lymph node metastasis. 117 patients were included in the study. The median age of the patients was 49 years. Before chemotherapy, 108 patients (92.3%) had tumor metastases in their axilla pathologically confirmed by tru-cut biopsy. Axillary downstage was obtained in 48.1% (n=52) of the patients after NACT. Of the 56 patients with axillary node positivity, 3 patients had no metastasis in the SLND evaluation (FNR=5.4%). The sensitivity of post-NACT MRI in detecting node positivity was 69.6%, the specificity was 90.2%, the positive predictive value (PPV) was 86.7% and the negative predictive value (NPV) was 76.4. SLND together with MRI predicted all node-positive patients (FNR=0%). In summary, SLND may not detect a group of patients with residual axillary lymph node metastases after NACT. We have shown that MRI can contribute to identifying these patients. If no metastases are detected by both methods (SLND and MRI), avoidance of axillary dissection may be an acceptable choice.

OBJECTIVE: To investigate the influence of music together with visual objects as an ambiance in the waiting room on anxiety levels of breast cancer patients scheduled to receive chemotherapy in outpatient setting for the first time. MATERIAL AND METHOD: Breast cancer patients planned to receive adjuvant or neoadjuvant chemotherapy for the first time between November 1, 2020, and July 31, 2021, were included. Two designs, including a standard waiting room (StWR) and an intervention waiting room (IWR) that was created by adding music and visual objects to the standard room, were constructed. These 2 designs were repeated sequentially in monthly periods, and a total of 104 patients with 52 in each group were randomized. The State Trait Anxiety Inventory (STAI) and Hospital Anxiety and Depression Scale (HADs) were used for assessments. Results of the patients in StWR and IWR groups were compared. RESULTS: Both HADs anxiety and STAI-state anxiety scale scores were lower in patients who waited in IWR compared to those who waited in StWR (p = 0.041, p = 0.012, respectively). In patients in the IWR group, mean heart rate was lower by 7.6 bpm (p = 0.009). No difference was found between the groups with regard to HADs depression score and STAI-trait anxiety score (p = 0.305, p = 0.535, respectively). For all patients, HADs anxiety scale (r = 0.400, p = < 0.001) and STAI-state anxiety scale (r = 0.475, p = < 0.001) scores increased as the waiting time increased. DISCUSSION AND CONCLUSION: The present study is the first to investigate the influence of adding music together with visual objects to the standard ambiance of the chemotherapy waiting room on anxiety levels of breast cancer patients. We propose that introduction of paintings, artificial plants, and music to the ambiance of the waiting room has a significantly positive effect on alleviating anxiety levels of cancer patients waiting for chemotherapy.

BACKGROUND: Breast cancer in young women is associated with aggressive biology. We analyzed histopathological and clinical properties of breast cancer patients diagnosed at ≤40 years of age. METHODS: Breast cancer patients who were admitted between 2015 and 2019 were included. Baseline characteristics of the patients with treatment-related outcomes were assessed. The study group was divided into two subgroups; <35 years old as "very young" and ≥35 years old as "young." RESULTS: The data of 137 patients (60 patients <35 years) were reviewed. The mean age was 34.7 years. The mean follow-up duration was 44.45 ± 26.39 months, and the mean disease-free survival was 36.17 ± 21.97 months. 11.4% of the patients were diagnosed with Stage 4 disease. Pathologic subtype was invasive ductal carcinoma in 86% of patients. 16.8% of the patients were luminal A, 38.7% luminal B, 30.5% were human epidermal growth factor receptor-2-positive type, and 15.3% were triple-negative. Only 5 (3.3%) patients had given birth after chemotherapy. During the follow-up period of early-staged diagnosed patients, metastatic disease occurred in 24.6%. The rate of distant metastasis development was statistically higher in the very young group (31% vs. 11%; P = 0.004). Thirteen patients (10.7%) died due to disease progression. Thirty-seven percent of the patients had a positive family history for either breast or ovarian cancer. CONCLUSIONS: Very young breast cancer patients seem to have a more aggressive disease course. The low rate of childbearing in this young patient population is conspicuous. An interdisciplinary approach for the management of this special patient population should be taken into consideration.

PURPOSE: Medical oncology physicians have been identified as one of the main risk groups for the development of burnout. Mindfulness as being aware of the moment nonjudgmentally seems to be a protective factor against burnout. We aimed to reveal mindfulness levels among medical oncology doctors and the potential impact of mindfulness on burnout syndrome. METHODS: In this cross-sectional study, the data of 285 medical oncology doctors were analyzed. The Mindful Attention Awareness Scale was used for mindfulness evaluation, and the Maslach Burnout Inventory was used for burnout assessment. After defining mindfulness levels among medical oncology doctors, the relationship between mindfulness and burnout was analyzed by the Pearson correlation and bivariate logistic regression tests. RESULTS: The mean Mindful Attention Awareness Scale score of participants was 54.52 ± 13.77. Mindfulness was associated with age (P < .001), having a hobby (P = .008), regular exercise (P = .001), professional title (P = .02), and professional experience (P = .02). As the level of mindfulness increased, emotional exhaustion and depersonalization decreased, whereas personal accomplishment increased significantly (all P < .001). In the regression analysis, mindfulness was significantly associated with all three subscales of burnout (all P < .01). CONCLUSION: We have demonstrated for the first time on such a large scale that higher levels of mindfulness were related with lower burnout among medical oncology physicians. These findings suggest the potential benefits of mindfulness-based interventions in reducing burnout levels in medical oncologists.

INTRODUCTION: We conducted a bibliometric analysis to determine the most impactful articles in the oncologic management of elderly cancer patients. MATERIAL AND METHODS: We searched Web of Science papers with six keywords: "geriat*" OR "older patient*" OR "older adult*" OR "elderly" and "*cancer" OR "oncolog*". We identified and analyzed the top 100 most-cited articles and abstracted information on topic, journal, first author, year, institution, level of evidence, and the adjusted citation index. RESULTS: Of the 100 most-cited papers, 62 had at least one author from the United States of America. Of the 62 United States papers, 18 had at least one author from Harvard University and 14 had authors from the National Institutes of Health. Among the 50 authors who contributed to the most-cited papers, Hurria is the most prolific author, with nine papers. Lung, breast, and colorectal cancers are the most studied cancer types, and the Geriatric 8 scale is the most studied scale. CONCLUSIONS: Our study is the first to analyze the top 100 most-cited studies in geriatric oncology. By comprehensively identifying the authors, institutes, journals, and the levels of evidence of these studies, we have created an easily accessible resource for practicing physicians to reference within this important area of oncology.
RESUMO
Mutations in two major breast cancer susceptibility genes, BRCA1 and BRCA2, have been identified to be the most important predisposing factors for the development of breast cancer. Thus, BRCA1/2 testing is a well-established method of choice for the assessment of developing breast cancer. Accordingly, here we aimed to report novel BRCA1/2 variations and distribution of previously known mutations and their association with the clinical course of breast cancer disease. A total of 287 breast cancer patients were enrolled from January 2017 through December 2019. Of these patients, 50 of them were identified to be positive for BRCA1/2. Next Generation Sequencing analysis was performed for the screening of exonic and intronic variations of BRCA1/BRCA2 genes. Notably, novel variations of 4448 G > A (Ser1843Asn) in BRCA1, and 982dupA (Thr328AspfsTer) and 7588C > T (Gln2530Ter) in BRCA2 gene were identified. The most common variations in BRCA1 gene were 5152 + 66G > A, 442-34C > T and 5266dupC. In BRCA2 gene, the most common variations were 9097dupA, 67 + 1G > A and 1114A > C. Novel variations of BRCA1 and BRCA2 genes were identified in breast cancer and might be useful predisposing factors in breast cancer diagnosis.

BACKGROUND/AIM: Doxorubicin (DOX) is a widely used and potent chemotherapeutic agent. However, serious dose-limiting toxicity through generation of free oxygen radicals is a commonly encountered clinical problem. The aim of the current study was to assess the protective role of onion (Allium cepa) extract (ACE) against DOX-induced hepatotoxicity in rats. METHOD: A total of 24 rats were randomly divided into 3 equal experimental groups: (1) DOX; (2) ACE + DOX; and (3) control groups. ACE was given orally as 1 mL of fresh ACE juice for 14 consecutive days followed by DOX injection. DOX was injected intraperitoneally in a single dose of 30 mg/kg body weight to induce hepatotoxicity, and the rats were killed after 48 h from injection. Control group was given saline only. RESULTS: In the ACE pretreated group (ACE + DOX), serum aspartate transaminase, alanine transaminase, and tissue malondialdehyde and glutathione levels were significantly lower, while superoxide dismutase and glutathione peroxidase were higher compared with the DOX group. The histopathological examination of liver specimens revealed parenchymal necrosis, proliferation of biliary duct in DOX group; while ACE pretreatment provided marked reduction in these changes. CONCLUSION: Our study indicates that pretreatment with ACE protects against DOX-induced hepatotoxicity due to the antioxidant properties of ACE. Further studies on efficacy of antioxidant treatment by ACE in DOX-mediated toxicity and underlying mechanisms would provide a better explanation.

BACKGROUND: Predictor factors determining complete response to treatment are still not clearly defined. We aimed to evaluate clinicopathological features, risk factors, treatment responses, and survival analysis of patient with advanced nonseminomatous GCTs (NSGCTs). MATERIALS AND METHODS: Between November 1999 and September 2011, 140 patients with stage II and III NSGCTs were referred to our institutions and 125 patients with complete clinical data were included in this retrospective study. Four cycles of BEP regimen were applied as a first-line treatment. Salvage chemotherapy and/or high-dose chemotherapy (HDCT) with autologous stem cell transplantation were given in patients who progressed after BEP chemotherapy. Post-chemotherapy surgery was performed in selected patients with incomplete radiographic response and normal tumor markers. RESULTS: The median age was 28 years. For the good, intermediate and poor risk groups, compete response rates (CRR) were, 84.6%, 67.9% and 59.4%, respectively. Extragonadal tumors, stage 3 disease, intermediate and poor risk factors, rete testis invasion were associated with worse outcomes. There were 32 patients (25.6%) with non-CR who were treated with salvage treatment. Thirty-one patients died from GCTs and 94% of them had stage III disease. CONCLUSIONS: Even though response rates are high, some patients with GCTs still need salvage treatment and cure cannot be achieved. Non-complete response to platinium-based first-line treatment is a negative prognostic factor. Our study confirmed the need for a prognostic and predictive model and more effective salvage approaches.

BACKGROUND: We aimed to evaluate prognostic factors and response rates to various treatment approaches to patients with synovial sarcoma in an advanced setting. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 55 patients (18 pts; 32.7% women) diagnosed with synovial sarcomas. Twenty had metastatic disease at the time of diagnosis while the remainder of the study group consisted of patients who developed metastatic or inoperable locally advanced disease during follow up. RESULTS: The median follow up time was 15 months (range: 1-53). Regarding outcomes for the 55 patients, 3 and 5 year overall survival rates were 26% and 14%, respectively. In univariate analyses among demographic factors female gender was associated with a better outcome (p=0.030). Patients with early progressing disease (<2 years) had a worse prognosis when compared to patient group with late relapse, but this difference did not reach statistical significance (p=0.056). According to multivariate Cox regression analysis patients who had undergone metastasectomy had a significant survival advantage (p=0.044). The overall response rate to different salvage chemotherapy regimens given as second line treatment was around 42.9-53.9% for all regimes. There were no statistically significant differences between chemotherapy regimens given in either second or third line settings in terms of overall survival. CONCLUSIONS: We observed no major differences in terms of response rate and survival between different salvage chemotherapy regimens. Although metastatic disease still carries a poor prognosis, metastasectomy was found to be associated with improved survival.
