RESUMO

We investigated expressions of PD-L1, LAG-3, TIM-3, and OX40L as immune checkpoint proteins, and MSI (repetitive short-DNA-sequences due to defective DNA-repair system) status were analyzed with immunohistochemistry from tissue blocks. Of 83 patients, PD-L1 expression was observed in 18.1% (n = 15) of the patients. None of the patients exhibited LAG-3 expression. TIM-3 expression was 4.9% (n = 4), OX40L was 22.9% (n = 19), and 8.4% (n = 7) of the patients had MSI tumor. A low-to-intermediate positive correlation was observed between PD-L1 and TIM-3 expressions (rho: 0.333, p < 0.01). Although PD-L1 expression was higher in grade 3 NET/NEC, MSI status was prominent in grade 1/2 NET.

RESUMO

PURPOSE: We aimed to investigate whether visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and skeletal muscle area (SMA) index are predictive for efficacy and hematological toxicity in ER + HER2-metastatic breast cancer (BC) patients who received CDK 4/6 inhibitors. METHODS: This retrospective cohort study analyzed 52 patients who were treated with CDK 4/6 inhibitors between January 2018 and February 2021. The values of VAT, SAT, SMA indices and hematological parameters were noted before the start, at the third and sixth months of this treatment. The skeletal muscle area (SMA) and adipose tissue measurements were calculated at the level of the third lumbar vertebra. A SMA-index value of <40 cm2/m2 was accepted as the threshold value for sarcopenia. RESULTS: Patients with sarcopenia had a worse progression-free survival (PFS) compared to patients without sarcopenia (19.6 vs. 9.0 months, p = 0.005). Patients with a high-VAT-index had a better PFS (20.4 vs. 9.3 months, p = 0.033). Only the baseline low-SMA- index (HR: 3.89; 95% CI: 1.35-11.25, p = 0.012) and baseline low-VAT-index (HR: 2.15; 95% CI: 1.02-4.53, p = 0.042) had significantly related to poor PFS in univariate analyses. The low-SMA-index was the only independent factor associated with poor PFS (HR: 3.99; 95% CI: 1.38-11.54, p = 0.011). No relationship was observed between body composition parameters and grade 3-4 hematological toxicity. CONCLUSION: The present study supported the significance of sarcopenia and low visceral adipose tissue as potential early indicators of poor PFS in patients treated with CDK 4/6 inhibitors.

RESUMO

BACKGROUND: In metastatic colorectal cancer (mCRC), the genetic structure and cell metabolism of the primary tumor lesion might be different from metastatic lesions. It is thought that cell-level glucose metabolism may differ due to the difference in RAS wild and mutant mCRC patients' prognosis. In this study, we aimed to compare 2-deoxy-2-[fluorine-18]-fluoro-D-glucose Positron Emission Tomography (18F-FDG PET/CT) uptake levels for KRAS mutation status and primary-metastatic tumor localization. METHODS: Our study is a retrospective cohort analysis that included RAS mutation status study and staging-oriented 18F-FDG PET/CT conducted on mCRC patients. RESULTS: There was no significant relationship between metastasis and primary tumor maximum Standardized uptake value (SUVmax) values according to the KRAS mutational status (P > 0.05). Patients with liver metastasis along with mutant BRAF mutation status had significantly higher SUVmax values in PET-CT scans (P = 0.04). There was a negative correlation between SUVmax values of lung metastases and overall survival (r = -0.35, P = 0.04). Patients with high carcinoembryonic antigen (CEA) levels had significantly higher SUVmax values of lung metastasis than patients with normal CEA levels (P = 0.009). Patients with high CA19-9 levels had significantly higher SUVmax values of liver, peritoneal, and bone metastasis than patients with normal CA19-9 levels (P = 0.002, P = 0.001, P = 0.004, respectively). There was no significant correlation between SUVmax values of metastasis and Lactate dehydrogenase (LDH) values. Liver metastasis of right-sided mCRCs had significantly higher SUVmax values (P = 0.03). CONCLUSION: We could not demonstrate a significant association between KRAS mutation and SUVmax values of PET scan in primary or metastatic tumor sites in advanced CRC.

RESUMO

Background: Prior speculation suggests that selective 5-hydroxytryptamine-3 receptors and neurokinin-1 receptor antagonists may increase arrhythmia risk and induce electrocardiographic changes. This study examined the effect of anti-emetic medications on arrhythmogenic potential and hemodynamic alterations. Methods: We considered patients aged 18 or above receiving chemotherapy between June 2013 and December 2013. Patients were grouped by anti-emetic medication: intravenous granisetron (Group G), oral aprepitant plus IV granisetron (Group AG), IV palonosetron (Group P), and oral aprepitant plus IV palonosetron (Group AP). We recorded blood pressure and electrocardiography initially and at the thirtieth minute post-medication, focusing on P dispersion, QTc dispersion, and systolic/diastolic blood pressure alterations. Results: The study included 80 patients (20 per group). Baseline systolic/diastolic blood pressure and P dispersion showed no significant variance. However, the baseline QTc dispersion was significantly lower in Groups P and AP than G and AG. The thirtieth-minute systolic/diastolic blood pressures were significantly lower than the baseline for Groups AG and AP, and the heart rates decreased in all groups. Group P showed significantly fewer blood pressure changes. Conclusions: We found no arrhythmogenic potential linked to granisetron, palonosetron, and aprepitant. Hypotension was more frequent at 30 min post-medication in granisetron or aprepitant recipients. Considering no hypotension occurred when using palonosetron alone, this treatment was deemed safer.

RESUMO

INTRODUCTION: Niraparib, a strong poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitor, contributed significantly to progression-free survival as a maintenance therapy in the platinum-sensitive period in both first-line and recurrent ovarian cancer, regardless of the BRCA mutation. Grade 3-4 anemia, which has a manageable side effect profile, especially hematological, is seen in almost 1 out of every 4 patients. To the best of our knowledge, there has been no reported case of pure red cell aplasia (PRCA) induced by niraparib treatment. CASE REPORT: A 65-year-old woman diagnosed with stage 3 serous carcinoma of the tuba received niraparib front-line maintenance treatment had grade 4 anemia after 3 months of niraparib treatment. She underwent bone marrow aspiration and biopsy because of refractory anemia, which needs red blood cell (RBC) transfusions despite interruption of treatment. MANAGEMENT AND OUTCOME: The patient was treated with 1 mg/kg methyl prednisolone, after histopathological assessment was consistent with PRCA. The hemoglobin count returned to the normal range with steroid treatment. DISCUSSION: In daily practice, it should be kept in mind that in the case of refractory anemia induced by niraparib, the underlying cause might be PRCA and can be improved with steroid administration.

RESUMO

The aim of our study was to evaluate the association between increased splenic volume (SV) and liver fibrosis indices in colon cancer patients receiving oxaliplatin-based adjuvant chemotherapy. Patients who received adjuvant oxaliplatin-based regimens with the diagnosis of stage II and III colon cancer were evaluated. Splenic volume measurements, liver function tests, platelet count, and non-invasive liver fibrosis indices [NAFLD fibrosis score (NFS), AST to platelet ratio (APRI), and Fibrosis-4 (FIB-4)] were measured before and after treatment. A 30% increase in SV after chemotherapy compared to baseline was considered increased SV. The rate of increase in SV was 57.7% in the whole group. An increase in SV was shown at a higher rate in patients treated with capecitabine and oxaliplatin (CAPOX) than those treated with 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) (66.3% vs. 36.8%, p = 0.002). Furthermore, the CAPOX regimen (OR: 2.831, 95% CI: 1.125-7.121; p = 0.027), and higher post-treatment FIB-4 score (OR: 3.779; 95% CI:1.537- 9.294, p = 0.004) were determined as independent risk factors for the increased SV. Our study revealed that increased SV had a significant association with higher FIB-4 score in patients treated with oxaliplatin-based chemotherapy.

RESUMO

BACKGROUND: The current study aimed to evaluate the effect of the time duration to reach the lowest prostate-specific antigen (PSA) from the onset of first-line hormonal treatment (time to nadir PSA, TTNpsa) on survival in castration-naive metastatic prostate cancer (CN-MPC) patients. METHODS: Eighty patients who had PSA response >80% with first-line hormonal therapy (luteinizing hormone-releasing hormone, LH-RH analog +/- bicalutamide) were included in this study. RESULTS: Under androgen deprivation therapy (ADT), a significant positive correlation was found between TTNpsa, nadir PSA (Npsa) duration, and progression-free survival (PFS) ( p < 0.001) and overall survival (OS) ( p < 0.001). There was no correlation between TTNpsa and Npsa duration. TTNpsa and Npsa durations were independently correlated with PFS and OS. In patients with TTNpsa value ≥19 weeks, the median PFS was 126 (95% CI, 68-184) weeks compared with TTNpsa <19-week group in which the median PFS was 44 (95% CI, 26-62) weeks ( p = 0.033). In patients with TTNpsa value ≥19 weeks, the median OS was 242 (95% CI, 169-315) weeks compared with TTNpsa <19-week group in which the OS was 156 (95% CI, 89-223) weeks ( p = 0.018). The median nadir PSA value was 1 ng/mL. The median PFS was significantly longer in the patient group with ≤1 ng/mL (137 weeks, 95% CI, 50-224) compared with the group with >1 ng/mL (41 weeks, 95% CI, 34-48) ( p < 0.001). The median OS was significantly longer in the patient group with nadir PSA ≤1 ng/mL (296 weeks, 95% CI, 220-272) compared to the group with >1 ng/mL (131 weeks, 95% CI, 84-178) ( p = 0.002). In patients with nadir PSA ≤1 ng/mL ( n = 40), there was no relationship between TTNpsa and Npsa duration with both PFS and OS. However, in patients with nadir PSA >1 ng/mL ( n = 40) subgroup, there was a significant positive correlation between TTNpsa and PFS, and OS ( p < 0.001, P = 0.016, respectively). CONCLUSION: In CN-MPC who received first-line ADT, especially in the group with the nadir PSA value >1 ng/mL, the duration of TTNpsa was positively correlated with PFS and OS.

RESUMO

OBJECTIVE: The ATM gene is one of the most common breast cancer (BC) susceptibility genes after BRCA1/2 and has been shown to be a moderate BC susceptibility gene. The association between ATM germline mutation and clinical features of BC is now unknown. In this article, clinicopathological features of BC patients with ATM germline heterozygous mutation were investigated. MATERIALS AND METHODS: Patients admitted to the Medical Genetics department of a tertiary hospital between January 2020 and December 2022 were examined. Only invasive BC patients with pathogenic mutation, likely pathogenic mutation, or variants of uncertain significance (VUS) were included in the study. RESULTS: In all, 121 patients were included in the study. The median age at the first cancer diagnosis of the patients was 44 years. Of the total number of patients, 75.2% (91) had the histological subtype of infiltrating ductal carcinoma, and 43% (52) had Luminal B molecular subtype features. At a median follow-up of 16 months, 5.8% (7) of patients developed cancer in the contralateral breast. In addition, 7.4% (9) of the patients developed a second primary cancer during follow-up. When the patients were compared according to ATM variant classification, the localization, histologic types, and molecular subtypes of the BC were not different between all groups (respectively; p=0.68, p=0.65, p=0.32). CONCLUSIONS: To the best of our knowledge, this is the first publication that evaluates the clinical and pathological characteristics of BC patients with germline heterozygous ATM mutations in the Turkish population. When patients were compared according to variant classifications of ATM mutation, patients' histological and molecular subtypes were similar.

RESUMO

INTRODUCTION: Resistance to immune checkpoint inhibitors (ICI) is a significant issue in metastatic renal cell carcinoma (mRCC), as it is in the majority of cancer types. An important deficiency in immunooncology today is the lack of a predictive factor to identify this patient group. Myeloid-derived suppressor cells (MDSC) are a type of cell that contributes to immunotherapy resistance by inhibiting T cell activity. While it accumulates in the tumor microenvironment and blood, it can also accumulate in lymphoid organs such as the spleen and cause splenomegaly. Therefore we aimed to evaluate the effect of increase in splenic volume, which can be considered as an indirect indicator of increased MDSC cells, on survival outcomes in mRCC patients. METHODS: We analyzed 45 patients with mRCC who received nivolumab as a second-line or subsequent therapy. Splenic volume was analyzed from baseline imaging before starting nivolumab and from control imaging performed within the first 6 months of treatment initiation. Additionally, we analyzed how patients' body mass index (BMI), IMDC risk score, ECOG performance status, nephrectomy status, neutrophil-lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR) and sites of metastasis. RESULTS: Median splenic volume change was 10% (ranging from - 22% to + 117%) during follow-up. Change in splenic volume was found to be associated with overall survival (OS) and progression-free survival (PFS) (p = 0.025, 0.04). The median PFS in patients with increased splenic volume was 5 months, while it was 17 months in patients without increased splenic volume. (HR 2.1, 95% CI (1-4), p = 0.04). The median OS in patients with increased splenic volume was 9 months, while it was 35 months in patients without increased splenic volume (HR 2.7, 95% CI (1.1-6.2), p = 0.025). In four patients with decreased splenic volume, neither PFS nor OS could reach the median value. Log-rank p value in respectively (0.015, 0.035), The group in which an increase in volume was accompanied by a high NLR had the shortest survival rate. Basal splenic volume was analyzed separately. However, neither PFS nor OS differed significantly. CONCLUSION: Our findings suggest that the change in splenic volume throughout immunotherapy regimens may be utilized to predict PFS and OS in mRCC patients undergoing treatment.

RESUMO

OBJECTIVE: Combination therapies such as FOLFIRINOX or gemcitabine-nanoparticle albumin-bound paclitaxel (GnP) are recommended for the first-line treatment of patients with advanced pancreatic cancer. The purpose of this study was to evaluate the efficacy of gemcitabine-based second-line therapies in patients whose disease progressed on FOLFIRINOX. METHOD: Patients diagnosed with advanced pancreatic cancer in 7 tertiary hospitals in Turkey were included. Patients were divided into 3 different groups according to their treatment regimens: GnP, gemcitabine doublet (gemcitabine-cisplatin or gemcitabine-capecitabine), and gemcitabine monotherapy. RESULTS: A total of 144 patients were included in the study. In the second-line treatment, 65% of patients were given GnP, 20% were given gemcitabine doublet, and 15% were given gemcitabine monotherapy. The median exposure of the patients to gemcitabine-based therapy was 3 cycles, whereas the median progression-free survival was calculated as 3.4 months. The median overall survival for patients who received GnP was 4.6 months, 6.4 months for patients who received gemcitabine doublet therapy, and 3.7 months for patients who received gemcitabine monotherapy ( P = 0.248). CONCLUSION: In conclusion, it has been shown that gemcitabine-based second-line treatments contribute to survival in patients with advanced pancreatic cancer. In addition, there was no difference in efficacy between gemcitabine monotherapy or combination treatments.

RESUMO

INTRODUCTION: Breast cancer is the most common cancer in women worldwide. One of the treatment choices used in hormone receptor positive and HER2 expression negative metastatic breast cancer is cyclin dependent kinase 4/6 (CDK) inhibitors. There are differences between the effects and adverse events of all CDK4/6 inhibitors. In this report, we describe a 48-year-old female patient with breast cancer who developed pulmonary infiltrates secondary to drug in the second year of follow-up with Ribociclib therapy. CASE REPORT: The patient who used ribociclib for metastatic breast cancer was admitted to hospital for routine controls. The patient, in the eighth month of ribociclib treatment, had no active complaints. In the patient's imaging, pulmonary infiltrates were detected in the lower lobe of the right lung. MANAGEMENT AND OUTCOME: The drug was continued in the patient who was asymptomatic and had no infectious signs. Pneumonitis, interstitial lung disease, tuberculosis, COVID-19 and other viral agents were excluded in the patient. A minimal increase in pulmonary infiltrates was observed in the follow-up. However, the patient who does not have any complaints is currently continuing ribociclib at 600 mg/day. DISCUSSION: The pulmonary infiltrates that developed in the patient increased with continued use of ribociclib, suggesting that this was due to ribociclib. The Naranjo Adverse Drug Reaction Probability Scale also indicates probable relationship.

RESUMO

BACKGROUND: PD-L1 and VISTA are thought to play a role in escape from the immune system, tumor progression, and treatment response in tumoral tissue. The current study aimed to evaluate the effects of radiotherapy (RT) and chemoradiotherapy (CRT) on PD-L1 and VISTA expression in head and neck cancers. METHODS: PD-L1 and VISTA expression were compared between the primary biopsy taken at the time of diagnosis and refractory tissue biopsies of patients who received definitive CRT or recurrent tissue biopsies of patients who had surgery followed by adjuvant RT or CRT. RESULTS: In total, 47 patients were included. Radiotherapy had no effect on the expression levels of PD-L1 and VISTA in patients with head and neck cancer (p = 0.542 and p = 0.425, respectively). A positive correlation was found between PD-L1 and VISTA expression (p < 0.001; r = 0.560). PD-L1 and VISTA expression in the first biopsy were found to be significantly higher in clinical lymph node-positive patients compared to node-negative patients (PD-L1 p = 0.038; VISTA p = 0.018). The median overall survival of patients with ≥ 1% VISTA expression in the initial biopsy was significantly shorter than that of patients with < 1% VISTA expression (52.4 vs. 110.1 months, respectively; p = 0.048). CONCLUSION: It was found that PD-L1 and VISTA expression did not change with RT or CRT. Further studies are needed to evaluate the relationship of PD-L1 and VISTA expression with RT and CRT.

RESUMO

BACKGROUND: The optimal sarcopenia measurement method in patients with a diagnosis of glioblastoma multiforme (GBM) is unknown. It has been found that temporal muscle thickness (TMT) may reflect sarcopenia and be associated with survival, but the relationship between temporal muscle area (TMA) and GBM prognosis has never been evaluated before. The primary outcome of the study was to evaluate the relationship between TMA/TMT and overall survival (OS) time in newly diagnosed GBM patients. METHODS: The data of patients who presented at the university hospital between January 2009 and January 2019 with a confirmed diagnosis of glioblastoma multiforme at the time of diagnosis were analyzed retrospectively. Temporal muscle thickness and TMA were measured retrospectively from preoperative MRIs of patients diagnosed with GBM. Due to the small number of patients and the failure to determine a cut-off value with acceptable sensitivity and specificity using ROC analysis, the median values were chosen as the cut-off value. The patients were basically divided into two according to their median TMT (6.6 mm) or TMA (452 mm2 ) values, and survival analysis was performed with the Kaplan-Meier analysis. RESULTS: The median TMT value was 6.6 mm, and the median TMA value was 452 mm2 . The median overall survival (OS) was calculated as 25.8 months in patients with TMT < 6.6 mm, and 15.8 months in patients with TMT ≥ 6.6 mm (p = 0.29). The median overall survival (OS) of patients with TMA < 452mm2 was 26.3 months, and the group with TMA ≥ 452mm2 was 14.6 months (p = 0.06). The median disease-free survival was 18.3 months (%95 CI: 13.2-23.4) in patients with TMT < 6.6mm, while mDFS was 10.9 (%95 CI: 8.0-13.8) months in patients with TMT ≥ 6.6mm (p = 0.21). The median disease-free survival was found to be 21.0 months (%95 CI: 15.8-26.1) in patients with TMA < 452 mm2 and 10.5 months (%95 CI: 7.8-13.2) in patients with TMA ≥ 452 mm2 (p = 0.018). DISCUSSION: No association could be demonstrated between TMT or TMA and OS of GBM patients. In addition, the median DFS was found to be longer in patients with low TMA. There is an unmet need to determine the optimal method of sarcopenia in GBM patients.

RESUMO

PURPOSE: Although adjuvant chemotherapy (AC) increases survival in early-stage gastric cancer, the effect of the time between gastrectomy and the initiation of AC on survival has not been clearly demonstrated. This study aimed to examine the effect of AC timing on survival. METHODS: The data of patients who received AC in the postoperative period with the diagnosis of stage II and stage III gastric cancer were analyzed retrospectively. The patients were separated into two groups based on a 4-week cut-off value between the date of gastrectomy and the initiation of AC. RESULTS: There were 151 patients enrolled in the study. It was determined that 63 (41.7%) patients started AC in the first 4 weeks and 88 (58.3%) patients after the first 4 weeks. Patients who received AC during the first 4 weeks had a median recurrence-free survival (RFS) of 46 months, while those who received AC after 4 weeks had a median RFS of 29 months (p = 0.039). The median overall survival (OS) for patients administered AC in the first 4 weeks was 65 months, compared to 45 months for those administered AC after 4 weeks (p = 0.036). The early time interval from surgery to AC resulted as an independent prognostic factor for both OS and RFS. CONCLUSION: The optimal time to start AC in patients with gastric cancer who underwent curative resection is unknown. This study reported that an interval shorter than 4 weeks was an independent prognostic risk factor for both OS and RFS.

RESUMO

OBJECTIVES: YouTube is a video-sharing platform used by ∼2 billion people per month, and videos are watched in high numbers in the medical field. In this study, we aimed to evaluate the scientific reliability and the relationship between the quality and popularity of the most watched YouTube videos on cancer and nutrition. METHODS: YouTube videos were evaluated independently by two oncologists. The video quality was evaluated according to the internationally valid medical video or document evaluation scores: DISCERN score, modified DISCERN score, Journal of the American Medical Association score, and Global Quality Scale score. RESULTS: Forty-six (58%) of the videos were uploaded to the platform by physicians or dietitians. Although 29 videos (36%) recommended a uniform diet, 51 videos (64%) had food suggestions that could be added to the diet. The most recommended foods were cruciferous (n = 16 [20%]; broccoli and cauliflower) and berries (n = 12% [15%]; strawberries, blueberries, and raspberries). When the video quality was evaluated according to the DISCERN score, only 17 (21%) videos were evaluated as good or excellent. There was a strong negative correlation between the DISCERN score and the number of video views and likes (r = -0.426; P < 0.001 and r = -0.226; P = 0.017, respectively). CONCLUSIONS: Videos about cancer and nutrition were highly watched, but the overall quality and reliability were low. Although the source of the information presented and its deficiencies and sometimes misleading statements were found, it was determined that the videos with less reliability were watched more. There is a need to produce quality content on YouTube or similar platforms.

RESUMO

PURPOSE: This study aims to investigate the factors that influence financial toxicity and its effects on both quality of life and psychological distress in Turkish cancer patients. METHODS: Data from 400 cancer patients receiving chemotherapy at a public university in Turkey was analyzed. The Comprehensive Score for Financial Toxicity (COST), Patient Health Questionnaire for Depression and Anxiety (PHQ-4), and Functional Assessment of Cancer Therapy-General (FACT-G) were used to measure financial toxicity, psychological distress, and health quality of life, respectively. RESULTS: Patients' median COST score was 22 (SD = 10.1; range: 1-44) and was consistent with mild financial toxicity. Financial toxicity was associated with lower education level (p < 0.001), lower monthly income (p < 0.001), being a woman (p = 0.021), living in another city (p = 0.012), and previous cancer surgery (p = 0.02). A negative and statistically significant correlation was found between financial toxicity and quality of life (r = - 0.139; p = 0.005) and psychological distress (r = - 0.398; p < 0.001). CONCLUSION: This investigation demonstrated that financial toxicity was a significant determinant of quality of life and psychological distress.

RESUMO

The rapid spread of COVID-19 infection and its negative effects on human health caused a great change in oncology practice. Although oncologists respond quickly to this change, anxiety caused by pandemics in some patients prevented cancer treatment. Although patients know that delaying cancer treatment can be life-threatening, they are concerned about contacting the hospital because they are afraid of becoming infected with COVID-19. Here, we would like to present three patients with delayed admission to the hospital to draw attention to the harmful consequences of COVID-19 fear in the community. These patients with cancer-related anxiety may exaggerate protective attitudes during the pandemic process, leading to delayed oncological treatment and poor prognosis of the patient.
