RESUMEN

Tyrosine kinase inhibitors (TKIs) have transformed cancer treatment but are associated with cardiovascular toxicity, including heart failure. This review examines the cardiotoxicity of pazopanib, a VEGFR-TKI, through two case reports and explores potential mechanisms. The importance of vigilant clinical monitoring to prevent cardiac dysfunction in cancer patients receiving pazopanib is emphasized. We present two cases of acute heart failure following pazopanib treatment. Case 1 involves a comorbidity-free, 62-year-old woman with metastatic renal cell carcinoma who experienced irreversible heart failure. In case 2, a 40-year-old woman with a history of anthracycline-containing chemotherapy developed reversible left ventricular systolic dysfunction following pazopanib discontinuation. Both patients received appropriate management for their heart failure symptoms. Case 1's condition rapidly deteriorated, leading to her unfortunate demise 3 months after starting pazopanib. In contrast, case 2's cardiac function improved after discontinuing pazopanib. The advent of TKIs has revolutionized cancer treatment, but their association with cardiovascular toxicity necessitates meticulous monitoring of patients. The cases presented here highlight the importance of recognizing and managing cardiotoxicity, particularly in patients without prior cardiovascular risk factors. Understanding the underlying mechanisms and risk factors for TKI-induced heart failure is crucial to optimize patient care and treatment outcomes. Oncologists should be vigilant in identifying clinical symptoms and closely monitoring cardiac function throughout TKI therapy.

RESUMEN

OBJECTIVE: To investigate the impact of cumulative cisplatin dose on clinical outcomes in locally advanced cervical cancer patients undergoing definitive chemoradiotherapy. METHODS: A retrospective analysis was conducted on 654 patients with stage IB3-IVA disease treated with definitive chemoradiotherapy. Radiotherapy was applied as external beam pelvic with or without para-aortic radiotherapy and brachytherapy. Concomitant chemotherapy was in the form of weekly or 3 weekly cisplatin. Data on demographics, treatment protocols, cumulative cisplatin dose, adverse effects, and survival outcomes were collected. Statistical analyses, including univariate and multivariate Cox regression models, were used to assess factors influencing progression free survival and overall survival. RESULTS: The median cumulative cisplatin dose was 210 mg (range 40-320), and ≥200 mg in 503 (76.9%) patients. Median follow-up was 35 months (range 1-150). The 5 year progression free survival and overall survival rates were 66.9% and 77.1%, respectively. Multivariate analysis identified poor performance status, non-squamous cell histology, presence of lymph node metastases, and hemoglobin <10 g/dL before chemoradiotherapy as poor prognostic factors for both progression free survival and overall survival in the whole group. When stage III cases were evaluated separately, the cumulative cisplatin dose <200 mg was found to be a significant poor prognostic factor in overall survival (hazard ratio 1.79, 95% confidence interval 1.1 to 3.0, p=0.031). CONCLUSION: Our study showed that a cumulative cisplatin dose >200 mg, particularly in patients with lymph node metastases, significantly improved overall survival. Factors such as anemia, toxicity related challenges, and comorbidities were identified as critical considerations in treatment planning. These findings emphasize the balance between maximizing therapeutic efficacy and managing toxicity, guiding personalized treatment approaches for locally advanced cervical cancer.

RESUMEN

INTRODUCTION: Male breast cancer, comprising approximately 1% of all breast cancer cases, often leads to the exclusion of male patients as a criterion in clinical trials. While the efficacy of Cyclin-dependent kinases 4 and 6 (CDK 4/6) inhibitors has been established in metastatic hormone receptor-positive (HR +) and human epidermal growth factor receptor 2-negative (HER2 -) breast cancer in women, limited data exist on their effectiveness in male patients. We aimed to evaluate the efficacy and safety of palbociclib or ribociclib in male patients with breast cancer. METHODS: This study is a multicenter, retrospective study. We included male patients with HR + and HER2-metastatic breast cancer who received palbociclib or ribociclib as first-line treatment. Our primary endpoints were progression-free survival (PFS), overall response rates (ORR), and drug-related adverse effects. RESULTS: A total of 46 male patients from 27 institutions were enrolled. The median age at initiation of CDK 4/6 inhibitors was 63.64 ± 13.69 years, with a median follow-up of 21.33 (95% CI 14.92-27.74) months. The ORR were 84% for palbociclib and 76.2% for ribociclib. The mPFS for the entire cohort was 28.06 months (95% CI 18.70-37.42). No significant difference in PFS was observed between palbociclib and ribociclib (mPFS: 24.46 months (95% CI 11.51-37.42) vs 28.33 months (95% CI 14.77-41.88), respectively, p = 0.211). No new adverse events were reported. DISCUSSION: This study demonstrates that palbociclib and ribociclib are effective and safe options for first-line treatment in male patients with HR + /HER2 - metastatic breast cancer. However, further prospective studies are warranted to establish their efficacy in this population.

RESUMEN

AIM: Sirolimus, a mammalian target of rapamycin inhibitor, inhibits cell growth and proliferation by controlling ribosome biogenesis and protein synthesis in vascular anomalies and cancers. However, most sirolimus studies on vascular anomalies were conducted in the pediatric population, with limited data in adults. In this study, we assessed the effectiveness and safety of sirolimus in adult patients with vascular malformation, a subtype of vascular anomaly. METHODS: We conducted a retrospective analysis of adult vascular malformation patients aged over 16, treated at Hacettepe University Cancer Institute from January 2013 to September 2022. Patient demographics and clinical characteristics were recorded. The primary outcome was the efficacy of sirolimus evaluated by response and disease control rates. The disease control rate was defined as the cumulative percentage of complete or partial responses, along with stable disease. The secondary endpoint was toxicity and safety. RESULTS: 38 patients with a median age of 21 (IQR: 18-33) were recruited. Prior to sirolimus treatment, 57.9% of patients had undergone other therapeutic interventions, predominantly sclerotherapy and surgery. The median follow-up time during sirolimus treatment was 18.5 (IQR: 11.3-74.5) months. The disease control rate was 92.1% (35/38). Head-neck localization was associated with better response rates (p = .001). Sirolimus was generally well tolerated and grade 1 or 2 oral mucositis (n = 4) and skin rash (n = 3) were the most common side effects. CONCLUSION: In this study, we found sirolimus was efficacious and well tolerated in adult patients with vascular malformation.

RESUMEN

We aimed to evaluate the seroconversion rates after two doses of inactive COVID-19 vaccine (CoronaVac) and the benefit of a third dose mRNA vaccine booster in patients with cancer receiving active treatment. Patients with solid tumors receiving active treatment (n = 101) and patients with no-cancer (n = 48) as the control group were included in the study. All the patients and controls had received two doses of CoronaVac and a third booster dose of the mRNA vaccine (Bnt162b2). Anti-SARS-CoV-2 Spike Receptor Binding Domain IgG antibody levels after the second and third dose were measured with quantitative ELISA. The median age of the patients was 66 (IQR 60-71). 79% of the patients were receiving chemotherapy, and 21% were receiving immunotherapy at the time of vaccination. Antibody levels measured after two doses of CoronaVac were significantly lower in patients with cancer than in the control group (median 0 µg/ml [IQR 0-1.17 µg/ml] vs median 0.91 µg/ml [IQR 0-2.24 µg/ml], respectively, P = .002). Seropositivity rates were 46.5% in patients with cancer and 72.9% in the control group (P = .002). Antibody measurement was performed in 26 patients after the third dose. Seroconversion rate increased from 46.5% to 88.5% (P < .001), and the antibody titers significantly increased with the third-dose booster (median 0 µg/ml [IQR 0-1.17 µg/ml] after two doses vs 12.6 µg/ml [IQR 1.8-69.1 µg/ml] after third booster dose, P < .001). Immunogenicity of CoronaVac is low in patients with cancer receiving active treatment, and administering a third dose of an mRNA vaccine is effective in terms of improving seroconversion rates.

RESUMEN

Pancreatic cancer is mostly metastaticat diagnosis. BR east CA ncer gene (BRCA) mutations are associated with platinum sensitivity in metastatic pancreatic cancer. However, curative surgery and complete remission are infrequent. In this report, we present a 42-year-old female patient diagnosed with BRCA-mutated pancreatic cancer with liver metastases. After 12 cycles of FOLFIRINOX, liver metastases disappeared and the patient underwent pancreaticoduodenectomy. The patient has been followed in complete remission for 5 years. To the best of our knowledge, the presented case is the longest recurrence-free survival after platinum-based therapy in metastatic pancreatic cancer with BRCA mutation. Our case emphasizes that investigating BRCA gene mutations at the time of diagnosis can be life-saving in these patients.

RESUMEN

Recent observational studies reported acute kidney injury (AKI) events in over 10% of the patients treated with immune checkpoint inhibitors (ICIs). However, these studies included patients treated in high-resource settings and earlier lines. Therefore, we aimed to assess the AKI rates and predisposing factors in ICI-treated patients from a limited resource setting. We evaluated 252 patients with advanced cancer for this retrospective cohort study. AKI events were defined by Kidney Disease Improving Global Outcomes criteria. The median age was 59 years. The melanoma (18.3%), non-small cell lung cancer (14.7%) and renal cell carcinoma (22.6%) patients comprised over half of the cohort. During the follow-up, 45 patients (17.9%) had at least one AKI episode. In multivariable analyses, patients with chronic kidney disease (CKD) [odds ratio (OR), 3.385; 95% confidence interval (CI), 1.510-7.588; P = 0.003], hypoalbuminemia (OR, 2.848; 95% CI, 1.225-6.621; P = 0.015) or renin-angiotensin-aldosterone system (RAAS) inhibitor use (OR, 2.236; 95% CI, 1.017-4.919; P = 0.045) had increased AKI risk. There was a trend towards increased AKI risk in patients with diabetes (OR, 2.042; 95% CI, 0.923-4.518; P = 0.78) and regular proton pump inhibitors use (OR, 2.024; 95% CI, 0.947-4.327; P = 0.069). In this study, we observed AKI development under ICIs in almost one in five patients with cancer. The increased AKI rates in CKD, hypoalbuminemia or RAAS inhibitor use pointed out a need for better onco-nephrology collaboration and efforts to improve the nutritional status of ICI-treated patients.

RESUMEN

BACKGROUND: Health technology assessment (HTA) is growing in low- and middle-income countries (LMICs) to ensure optimal use of limited resources. However, the impact of HTAs on decision making in LMICs has been limited. The study aimed to provide an overview of Turkiye's progress since establishing the first HTA agency in 2012. METHODS: The web sites of three national HTA agencies in Turkiye were searched for HTA guidelines and national HTA reports. The HTA guidelines were assessed by two researchers independently against the key principles of HTA developed by Drummond et al., and the HTA reports against the national guidelines. RESULTS: The study included one HTA guideline and eight national HTA reports. The guideline included very limited technical guidance. Compliance with the principles was poor to moderate, and significant methodological limitations were identified. The reports were inconsistent regarding the scope and the HTA assessment criteria. The link between HTA findings, HTA decision making, and health policies were not clear. DISCUSSION: The inconsistencies between the reports and the methodological limitations demonstrate the need for national HTA guidelines. Improving the characteristics of the HTA might impact implementation. Among the key issues is transparency regarding priority setting, the HTA process, and decision making. CONCLUSION: Establishing and adopting national HTA guidelines at international standards is needed. Involving external scientific committees and health economists in the HTA processes might help ensure that the key principles of HTA are followed. The study findings might be helpful for countries that are developing their HTA systems.

RESUMEN

PURPOSE: A significant portion of patients with locally advanced head and neck squamous cell carcinoma (HNSCC) relapse despite multimodality treatment denoting the need for biomarkers. The pan-immune-inflammation value (PIV) is a recently developed blood count-based prognostic biomarker. We evaluated the relationship between PIV and survival in locally advanced HNSCC patients treated with chemoradiotherapy (CRT). METHODS: A total of 199 patients who underwent CRT at Hacettepe University Oncology Hospital were included. The relationship between clinical and laboratory parameters with overall survival (OS) and disease-free survival (DFS) was analyzed by multivariate analyses. RESULTS: The median age was 59 years and 90.5% of the patients were male. 66.8% of the patients had laryngeal primaries, and 78.9% had T3-T4 disease. 84.9% of the patients received CRT with cisplatin. The optimal PIV threshold value was calculated as 404 in ROC analyses. This PIV value had 75.8% sensitivity and 70.4% specificity for OS prediction (AUC 0.781; 95% CI 0.715-0.846; p < 0.001). In multivariate analyses, high PIV levels (≤ 404 vs. > 404, HR 2.862; 95% CI 1.553-5.276; p = 0.001), higher NLR (≤ 2.5 vs. > 2.5, HR 1.827; 95% CI 1.017-3.281; p = 0.044) levels and ECOG performance score of 2 (HR 2.267; 95% CI 1.385-3.711; p = 0.001) were associated with shorter OS. These factors were associated with shorter DFS also (HR for PIV 2.485, 95% CI 1.383-4.467, p = 0.002). CONCLUSIONS: We observed shorter OS and DFS in locally advanced HNSCC patients with high PIV levels. If prospective studies support our findings, the PIV score could be a prognostic biomarker in HNSCC.

RESUMEN

OBJECTIVES: The aim of the study was to identify predictors of the masticatory muscle activity during chewing (MMA) of the masseter and temporalis anterior (TA) muscles in patients with unilateral myogenous temporomandibular disorder (mTMD). MATERIALS AND METHODS: This observational and cross-sectional study included 109 patients diagnosed with unilateral mTMD. Surface electromyography was used to separately evaluate the MMA of the masseter and TA on the affected and unaffected sides. Also, pain intensity (with a visual analog scale), pressure pain threshold (with an algometer), active pain-free maximum mouth opening and temporomandibular joint lateral movements (with a ruler), cervical range of motions (with a goniometer), and TMD severity (with a Fonseca Anamnestic Index) were assessed. Various statistical methods were used to predict the MMA of the masseter and TA, including standard, forward, and best subsets multiple regression models. RESULTS: While there were significant correlations between the MMA of the masseter and TA and pain intensity, pressure pain threshold values, and TMD severity, they were not found with other variables. These parameters were also predictive factors for MMA of both muscles (p < 0.05). CONCLUSIONS: According to the present study, pain intensity, muscle and joint tenderness, and the severity of the disorder are predictive factors for MMA of the masseter and TA muscles in patients with mTMD. It is recommended that these parameters be considered when establishing clinical evaluation and treatment programs focusing on MMA in patients with mTMD. CLINICAL RELEVANCE: The pain intensity, masticatory muscles and TMJ tenderness, and disorder severity are predictors for MMA of the masseter and TA in patients with mTMD. Pain intensity has the most significant importance.

RESUMEN

Background/aim: To compare the effectiveness of instrument-assisted soft tissue mobilization (IASTM) and extracorporeal shock wave therapy (ESWT) used in myofascial pain syndrome (MPS) and to determine whether they are superior to conservative treatment (CT). Materials and methods: A total of 42 female patients (aged 18-60 years) diagnosed with MPS were enrolled and randomly assigned to either the CT (n = 14), CT+IASTM (n = 14), or CT+ESWT group (n = 14). All of the groups received treatment for 3 weeks (CT: 5 sessions per week, 15 sessions in total, ESWT and IASTM: 2 sessions per week, 6 sessions in total). Neck stretching exercises were given to all of the patients as a home program. The pain intensity of the patients was determined using the visual analog scale (VAS). The pressure pain threshold (PPT) was measured with an algometer. Cervical joint range of motion (ROM) was measured with a cervical ROM (CROM) device. Pain, cervical disability, quality of life, and sleep disturbances were evaluated with the Neck Outcome Score (NOOS). Depression and anxiety parameters were evaluated with the Hospital Anxiety and Depression Scale (HADS). Evaluations were made before treatment and 3 days after the last treatment session. Results: The CT+IASTM group was more successful than the other groups in terms of pain intensity, PPT, and improvements in the ROM parameters (p < 0.05). No significant difference was found between the NOOS and HADS scores of the groups when the posttreatment changes were compared to pretreatment (p > 0.05). Conclusions: All 3 of these treatments can be used to alleviate the negative effects of MPS. IASTM treatment can be preferred primarily in the creation of combined treatment programs for patients with ROM limitations and low PPTs.

RESUMEN

AIM: To compare survival outcomes, response rates, and adverse events (AEs) in proton pump inhibitor (PPI) user and non-user patients with metastatic colorectal cancer (mCRC) treated with regorafenib. METHODS: We included 272 patients with mCRC treated with regorafenib in this study. Patients were divided into two categories according to their status of PPI use. The primary endpoint was overall survival (OS). The secondary endpoints were time to treatment failure (TTF), response rates, and safety. To exclude immortal time bias in survival analyses, we compared PPI non-user patients and all patients. RESULTS: There were 141 and 131 patients in the PPI non-user and user groups. Baseline characteristics were similar in each group. Pantoprazole was the most used PPI. At the median 35.2 (95% confidence interval (CI): 32.6-37.9) months follow-up, the median OS was similar in PPI non-user and all patients (6.9 months (95% CI: 5.3-8.5) and 7.7 months (95% CI:6.6-8.8), p = 0.913). TTF was also similar in PPI non-user and all patients (3.3 months (95% CI: 2.7-3.9) and 3.5 months (95% CI: 3.0-4.0), p = 0.661). In multivariable analysis, no statistically significant difference was observed between PPI user and non-user groups in OS and TTF (hazard ratio (HR), 0.99; 95% CI, 0.77-1.28; p = 0.963 for OS; HR, 0.93; 0.77-1.20, p = 0.598 for TTF). The objective response rates (ORR) were similar in the PPI non-user and user groups (19.8% and 16.8%, p = 0.455). The rates of any grade AEs were also similar in each group. CONCLUSION: This study found no worse outcome in the combined use of PPI and regorafenib among patients with mCRC.

RESUMEN

PURPOSE: The HER2-low breast cancer is a newly recognized entity with the clinical characteristics is yet to be defined. We hypothesized that HER2-low breast cancer could lead to an increased rate of brain metastases in patients with localized breast cancer. We tested this hypothesis in a large cohort of breast cancer patients with long follow-up. METHODS: We included 2686 adult breast cancer patients followed up in Hacettepe University Cancer Center. Patients with 1 + positive HER2 expression and 2 + HER2 expression with a negative FISH were categorized as HER2-low disease. We evaluated the brain metastasis risk with binary logistic regression analyses and reported odds ratios (OR) with 95% confidence intervals (CI). RESULTS: During a median 95.4 (IQR 72.6-123.1) month follow-up, 184 patients developed brain metastasis (6.9%). The brain metastases were developed in 5.1% of the patients with HER2-negative disease, 8.5% of the patients with HER2-low disease, and 10.1% of the patients with HER2-positive disease. A multivariable binary logistic regression model demonstrated an increased risk of brain metastasis in patients with HER2-low disease (OR: 1.611, 95% CI 1.055-2.460, p = 0.027) and in HER2-positive patients (OR: 1.837, 95% CI 1.308-2.580, p < 0.001). Additionally, HR + -HER2-low disease was associated with a decreased DFS compared to HR + -HER2-negative disease (p = 0.008). CONCLUSION: In this study, we observed an increased risk of brain metastasis in localized breast cancer patients with HER2-low disease. We think that a high level of vigilance and a low threshold for brain imaging could benefit HER2-low breast cancer patients similar to the patients with HER-positive disease.

RESUMEN

INTRODUCTION: Polypharmacy is a common problem in older cancer patients, although the data about polypharmacy and potentially inappropriate prescription practices is limited in patients treated with immune checkpoint inhibitors (ICIs). Therefore, we aimed to evaluate the polypharmacy frequency and drug-drug interactions in older cancer patients (≥65 years) treated with ICIs. METHODS: A total of 70 geriatric patients with advanced cancer were included. The polypharmacy was defined as regular use of 5 or more drugs. The START/STOPP Criteria Version 2 was used for the potentially inappropriate medications (PIM) and potential prescription omissions (PPO). The Medscape Drug Interaction Checker was used for potential drug-drug interactions. RESULTS: The patients had a median of 6 regular drugs, and polypharmacy was present in 77.1%. The polypharmacy risk was significantly increased in patients over 75 years of age (p = 0.028) and with opioid use (p = 0.048). The 50% of patients had category D or X interactions. Patients with higher Charlson Comorbidity Index had significantly increased risk for drug interactions (CCI ≤10 vs. >10, p = 0.017). The PIMs were present in 44.3% and the PPOs in 68.6% of the patients. While the overall survival and immune related adverse events were similar according to polypharmacy, in patients using seven or more drugs, the acute kidney injury risk was increased (HR: 4.667, p = 0.038). CONCLUSION: In this study, we observed a high rate of polypharmacy and inappropriate prescription practices in ICI-treated patients. These issues pointed out the need for improved general medical care and attention for better comedication management in ICI-treated patients.

RESUMEN

BACKGROUND: We aimed to evaluate the efficacy of fulvestrant and its affecting clinical factors, including the optimal sequencing of fulvestrant and chemotherapy in a real-life cohort. METHODS: The data of 256 metastatic hormone-positive breast cancer patients treated with fulvestrant were evaluated. The association of clinical factors with survival was analyzed with Kaplan-Meier and Cox-regression analyses. RESULTS: The median age of patients was 57 years. More than half of the patients used fulvestrant in later lines and after chemotherapy (75.8%). The median progression-free (PFS) and overall survival (OS) of all cohort were 6.05 ± 0.56 and 29.70 ± 1.61 months, respectively. Primary endocrine resistance (HR: 1.989, 95% CI: 1.430-2.766, <0.001), use of fulvestrant after chemotherapy (HR: 1.849, 95% CI: 1.182-2.891, p = 0.007) and visceral metastases (HR: 1.587, 95% CI: 1.128-2.233, p = 0.008) were associated with decreased OS in multivariate analyses. Sixteen patients were treated with trastuzumab and fulvestrant combination. The overall response rate (p = 0.340), disease control rate (p = 0.076), and OS (p = 0.289) and PFS (p = 0.276) were similar to overall cohort. DISCUSSION: In our experience, fulvestrant treatment was associated with comparable OS to clinical trials in a large cohort of patients. Patients treated with fulvestrant before chemotherapy were garnered significantly more benefit.

RESUMEN

BACKGROUND: Perioperative FLOT regimen is a standard of care in locally advanced operable gastric and GEJ adenocarcinoma. We aimed to determine the efficacy, prognostic factors of perioperative FLOT chemotherapy in real-life gastric and GEJ tumors. METHODS: The data of patients who were treated with perioperative FLOT chemotherapy were retrospectively analyzed from 34 different oncology centers in Turkey. Baseline clinical and demographic characteristics, pretreatment laboratory values, histological and molecular characteristics were recorded. RESULTS: A total of 441 patients were included in the study. The median of age our study population was 60 years. The majority of patients with radiological staging were cT3-4N(+) (89.9%, n = 338). After median 13.5 months (IQR: 8.5-20.5) follow-up, the median overall survival was NR (95% CI, NR to NR), and median disease free survival was 22.9 (95% CI, 18.6 to 27.3) months. The estimated overall survival at 24 months was 62%. Complete pathological response (pCR) and near pCR was achieved in 23.8% of all patients. Patients with lower NLR or PLR have significantly longer median OS (p = 0.007 and p = 0.033, respectively), and patients with lower NLR have significantly longer median DFS (p = 0.039), but PLR level did not affect DFS (p = 0.062). The OS and DFS of patients with better ECOG performance scores and those who could receive FLOT as adjuvant chemotherapy instead of other regimens were found to be better. NLR was found to be independent prognostic factor for OS in the multivariant analysis. At least one adverse event reported in 57.6% of the patients and grade 3-4 toxicity was seen in 23.6% patients. DISCUSSION: Real-life perioperative FLOT regimen in operable gastric and GEJ tumors showed similar oncologic outcomes compared to clinical trials. Better performance status, receiving adjuvant chemotherapy as same regimen, low grade and low NLR and PLR improved outcomes in real-life. However, in multivariate analysis, only NLR affected OS.

RESUMEN

BACKGROUND: We aimed to investigate the prognostic value of red cell distribution width (RDW) in metastatic renal cell carcinoma (mRCC) patients treated with targeted therapy, including sunitinib and pazopanib. METHODS: A total of 104 mRCC patients were included. The Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS), and the long-rank test was used for comparison. Univariate and multivariate Cox proportional hazards models were used to determine the association between RDW and PFS and OS. RESULTS: The PFS and OS of all cohorts were 11.8 mo and 25.9 mo, respectively. Receiver operating characteristic analysis revealed that RDW level ≥15.4 was the optimal cutoff value for OS prediction with 73.53% sensitivity and 61.11% specificity (area under curve: 0.64, P = 0.012). RDW level ≥15.4 was found as an independent prognostic parameter for OS when adjusted for the number of covariates, including the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) scoring system (hazard ratio: 1.125, 95% confidence interval: 1.024-2.235, P = 0.014). CONCLUSIONS: Our study revealed that high RDW level, a routinely and easily assessed marker, was significantly associated with worse survival outcomes in mRCC patients treated with targeted therapy.

RESUMEN

The present work aimed to compare antioxidant response and lipid peroxide detoxification capacity of an arctic-alpine species Arabis alpina to its close relative model species Arabidopsis thaliana under acute short duration (3 h and 6 h) UV-B stress (4.6 and 8.2 W/m2). After 3 and 6 h exposure to UV-B, A. alpina showed lower lipid peroxidation and H2O2 accumulation when compared to A. thaliana. Moreover, Fv/Fm value of A. thaliana dropped to 0.70, while A. alpina dropped to 0.75 indicating better protection of PSII in this species. For elucidation of the antioxidant response, activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), ascorbate peroxidase (APX), glutathione reductase (GR) and dehydroascorbate reductase (DHAR) were measured. SOD induction with 6 h of UV-B was more prominent in A. alpina. Also, A. alpina had higher chloroplastic FeSOD activity when compared to A. thaliana. APX activity was also significantly induced in A. alpina, while its activity decreased at 3 h or did not change at 6 h in A. thaliana. A. alpina was able to maintain constant CAT activity, but drastic decreases were observed in A. thaliana at both time points. Moreover, A. alpina was able to maintain or induce aldehyde dehydrogenase (ALDH), alkenal reductases (AERs) and glutathione-S-transferases (GST) activity, while an opposite trend was observed in A. thaliana. These findings indicate that A. alpina was able to maintain/induce its antioxidant defence and lipid peroxide detoxification conferring better protection against UV-B.

RESUMEN

The aim of this study was to assess the impact of coronaphobia on treatment and follow-up compliance in cancer patients. The records of 230 cancer patients were reviewed. Coronaphobia was assessed via the validated COVID-19 Phobia Scale (C19P-S). A total of 64% of the patients had a high coronaphobia score. Among them, 59% were noncompliant. In multivariate logistic regression analysis, low educational status, treatment type, following COVID-19 news, having knowledge about COVID-19 transmission and higher C19P-S score were associated with noncompliance (p = 0.006, p < 0.001, p = 0.002, p = 0.002 and p = 0.001, respectively). Multivariate analysis revealed that having knowledge about COVID-19 transmission was related to a higher C19P-S score (p = 0.001). The cancer patients studied had significant coronaphobia. Moreover, greater coronaphobia was significantly associated with noncompliance with follow-up and treatment.

RESUMEN

BACKGROUND: Unplanned readmission in the first 30 days after discharge is an important medical problem, although the data on cancer patients is limited. So we planned to evaluate the rates and causes of early readmissions and the predisposing factors. METHODS: Patients hospitalized in Hacettepe University Oncology services between August 2018 and July 2019 were included. The demographic features, tumor stages, regular drugs, last laboratory parameters before discharge, and readmissions in the first 30 days after discharge were recorded. The predisposing features were evaluated with univariate and multivariate analyses. RESULTS: A total of 562 hospitalizations were included. The mean age of the patients was 58.5 ± 14.5 years. Almost 2/3 of the hospitalizations were due to symptom palliation and infections. Eighty-three percent of the patients had advanced disease, and over 60% had an ECOG score of 2 and above. In the first 30 days after discharge, 127 patients were readmitted (22.6%). Advanced stage disease, presence of polypharmacy (5 or more regular drugs), hospitalization setting (emergency department (ED) vs. outpatient clinic), and hypoalbuminemia (< 3 gr/dL) were associated with a statistically significant increase in the risk of readmission. Among these factors, advanced-stage disease (HR: 2.847, 95% CI: 1.375-5.895), hospitalization from ED (HR: 1.832, 95% CI: 1.208-2.777), and polypharmacy (HR: 1.782, 95% CI: 1.173-2.706) remained significant in multivariate analyses. CONCLUSIONS: In this study, 22% of cancer patients had early readmissions. The readmission risk increased in patients with advanced disease, hospitalization from ED, and polypharmacy. The optimal post-discharge plan may reduce readmissions in all oncology patients, with priority for these patient groups.
