RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVES: Head and neck cancers (HNCs) represent a significant global health concern due to high morbidity and mortality rates. Despite therapeutic advances, the prognosis for advanced or recurrent cases remains challenging. Nivolumab obtained approval for recurrent or metastatic HNC based on the Phase III CheckMate 141 trial. This study aimed to evaluate the real-world outcomes of nivolumab in patients with non-nasopharyngeal HNC. DESIGN: In this multicenter retrospective study, we analyzed 124 patients with recurrent or metastatic non-nasopharyngeal HNC who received nivolumab in the second-line setting and beyond. Data were collected from 20 different cancer centers across Turkey. The effectiveness and safety of the treatment and survival outcomes were evaluated. RESULTS: Nivolumab exhibited favorable clinical responses, yielding an objective response rate of 29.9% and a disease control rate of 55.7%. Safety assessments revealed a generally well-tolerated profile, with no instances of treatment discontinuation or mortality due to side effects. Survival analysis disclosed a median overall survival (OS) of 11.8 (95% CI 8.4-15.2) months. Multivariate analysis revealed that ECOG-PS ≥ 1 (HR: 1.64, p = 0.045), laryngeal location (HR: 0.531, p = 0.024), and neutrophil-to-lymphocyte ratio > 3.5 (HR: 1.97, p = 0.007) were independent predictors of OS. CONCLUSIONS: Nivolumab is an effective and safe treatment option for patients with recurrent or metastatic non-nasopharyngeal HNC in real-world settings. Further studies are needed on factors affecting response to treatment and survival outcomes.

RESUMEN

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.

RESUMEN

BACKGROUND: We aimed to evaluate the relationship between sarcopenia, myosteatosis, and systemic inflammatory response biomarkers and their prognostic role in stage 2 and 3 gastric cancer patients. METHODS: This study included 84 patients with stage 2 or 3 gastric cancer who underwent a gastrectomy. Computed tomography scans were used to determine the skeletal muscle index (SMI) at the third lumbar vertebra level for sarcopenia and myosteatosis. RESULTS: Based on the Asian Working Group of Sarcopenia (AWGS2019) criteria, the sarcopenia incidence was 36.9% and that of myosteatosis 46.4%. Univariate analysis showed that sarcopenia (48 vs. 14 mo, p < 0.001), myosteatosis (45 vs. 16 mo, p = 0.016), a low prognostic nutritional index (60 vs. 15 mo, p = 0.003), stage 3 (104 vs. 21 mo, p = 0.013), and old age (45 vs. 16 mo, p = 0.015) were poor prognostic markers. Multivariate analysis revealed that sarcopenia (AWGS2019), age, and stage significantly affected overall survival (hazard ratio: 3.31, 95% CI: 1.85-5.1; 1.96, 95% CI: 1.06-6.63; 2.5, 95% CI: 1.2-5.1, respectively). CONCLUSION: We showed that sarcopenia directly affects overall gastric cancer survival.

RESUMEN

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.

RESUMEN

Sarcomatoid renal cell carcinoma (sRCC) is a rare variant of renal cell carcinoma (RCC) and is associated with a poor prognosis. We reviewed the outcomes of patients from oncology centers in Turkey. Our aim is to share our real-life experience and to contribute to the literature. The demographic and clinical features, treatment, and survival outcomes of 148 patients with sRCC were analyzed. The median age at the time of diagnosis was 58 years (range: 19-83 years). Most patients (62.8%) had clear-cell histology. Most patients were in the intermediate Memorial Sloan-Kettering Cancer Center (MSKCC) risk group (67.6%) and were stage 4 at the time of diagnosis (63.5%). The most common sites of metastasis were the lung (60.1%), lymph nodes (47.3%), and bone (35.8%). The patients received a median of two lines (range: 0-6) of treatment. The most common side effects were fatigue, hematological side effects, hypertension, and hypothyroidism. The median follow-up was 20.9 months (range: 1-162 months). The median overall survival (OS) was 30.8 months (95% confidence interval: 24.9-36.7 months). In multivariate analysis, high MSKCC scores, sarcomatoid differentiation rates >50%, having stage 4 disease, and having lung metastasis at the time of diagnosis were independent factors for poor prognosis affecting OS. No difference was observed between patients who received tyrosine kinase inhibitor (TKI) as the first or second-line treatments. Similarly, no difference between TKI and immunotherapy as the second-line treatment. In conclusion, sRCC is a rare variant of RCC with a poor prognosis and response to treatment. Larger-scale prospective studies are needed to define an optimal treatment approach for longer survival in this aggressive variant.

RESUMEN

INTRODUCTION: The efficacy of immune checkpoint inhibitors (ICIs) against malignant melanoma and numerously solid tumors has been demonstrated in several clinical studies. The incidence of immune-related adverse effects (irAEs) has increased after the rapidly expanding indications and clinical applications of ICIs. We present a case of nivolumab and ipilimumab-induced encephalitis with rapidly worsening consciousness and full recovery following ICIs suspension and high-dose steroid coupled with intravenous immunoglobulin (IVIG). CASE REPORT: A 67-year-old woman was diagnosed with stage 4 BRAF wild malignant melanoma with metastasis to the axillary and mediastinal lymph nodes. Beyond progression with dacarbazine, ipilimumab and nivolumab combination were administered at the second-line treatment of metastatic setting. A week after the first cycle patient was reported to have a fever of more than 38°C. Subacute cognitive impairment including mild changes in behavior was reported on the third day of fever. She suddenly developed confusion, dysarthria, and motor dysfunction a few days later. Due to the altered mental status accompanied by fever, lumbar puncture was performed with a pre-diagnosis of encephalitis, meningitis, and leptomeningeal carcinomatosis. MANAGEMENT & OUTCOME: After excluding viral and autoimmune encephalitis, high-dose methylprednisolone was administered in addition to IVIG for 5 days with the diagnosis of immunotherapy-related encephalitis according to the recommendations for the management of irAEs. On the second day of the treatment patient's neurological status improved gradually. DISCUSSION: Being aware of symptoms of serious neurological irAEs associated with ICIs can prevent complications and improve survival.

RESUMEN

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.

RESUMEN

Inflammatory myofibroblastic tumors (IMTs) are mesenchymal solid tumors, in which anaplastic lymphoma kinase (ALK) gene rearrangement might be detected. A 48-year-old female presented with IMT of lung, treated with surgery. After a 39-month disease-free survival metastatic recurrence was occurred involving soft tissues both infra- and supradiaphragmatic regions. The biopsies obtained from metastatic regions confirmed the recurrence with ALK rearrangement in immunohistochemistry. Initial partial response observed early in treatment course remained as a stable disease with crizotinib treatment. Although an excellent outcome with overall survival of 57 months was observed in our case, there is not enough information about survivals with crizotinib and the treatment options beyond progression. Therefore, every individual case has a unique value paving the way for more effective treatment.

RESUMEN

We aimed to compare the efficacy and the safety of the FOLFOX and the FLOT regimens in metastatic gastric cancer (mGC) as first-line treatment. It was a retrospective multicenter observational study. The comparisons between groups were conducted in terms of progression-free survival (PFS), overall survival (OS), objective response rate (ORR) and hematologic adverse events. Seventy-nine patients, diagnosed with mGC between March 2012 and December 2019, treated with FOLFOX (n = 43) or FLOT (n = 36) regimens as first-line treatment were included in the study. The mPFS was 10.9 months [95% confidence interval (CI), 5.8-16.1] in the FLOT arm and 7.1 months (95% CI, 5.1-9.1) in the FOLFOX arm (P < 0.001). The ORR was 63.9% in the FLOT arm and 30.2% in the FOLFOX arm (P = 0.003). The mOS was 13.3 months (95% CI, 11.3-15.4) in the FLOT arm and 10.9 months (95% CI, 8.2-13.5) in the FOLFOX arm (P = 0.103). The hematologic adverse events in all grades were 88.4% (n = 38) in the FOLFOX arm compared with 80.6% (n = 29) in the FLOT arm (P = 0.335). The FLOT regimen might be a preferred option in mGC with an improved PFS and ORR compared with the FOLFOX regimen.

RESUMEN

INTRODUCTION: Acute pancreatitis associated with Pazopanib has been reported in the literature. Bitter Melon (Momordica Charantia) is traditionally used as a folk medicine in many regions. In this report, we describe a 65-year-old patient with a diagnosis of renal cell carcinoma, admitted to the hospital with symptoms of acute pancreatitis at the 8th year of pazopanib treatment. CASE REPORT: The patient diagnosed with renal cell carcinoma was admitted to the hospital with the complaint of abdominal pain, nausea, and vomiting in the 8th year of Pazopanib treatment. It was noticed from the patient's history that he had received Bitter Melon extract for 4 days prior to the beginning of his complaints (100-150 ml/day). Levels of serum amylase and lipase were measured as 9163 U/L and 14,206 U/L, respectively. MANAGEMENT & OUTCOME: Pazopanib drug was held. The patient was treated for acute pancreatitis. Pazopanib treatment was started again after the clinical condition of the patient had improved and levels of serum amylase and lipase had returned to normal levels. Levels of serum amylase and lipase did not increase again after re-administration of pazopanib treatment. DISCUSSION: It is thought that Bitter Melon extract and pazopanib interaction might have led to acute pancreatitis. To the best of our knowledge, this case is the first to highlight the interaction of Bitter Melon extract with pazopanib. The Drug Interaction Probability Scale indicates that there is a probable association between bitter melon and acute pancreatitis.

RESUMEN

INTRODUCTION: Favipiravir is an antiviral agent that is recently used for SARS-CoV2 infection. The drug-drug interactions of favipiravir especially with chemotherapeutic agents in a patient with malignancy are not well known. CASE REPORT: The patient diagnosed with metastatic osteosarcoma was given high dose methotrexate treatment, and favipiravir was started on the third day of the treatment with suspicion of SARS-CoV2 infection. Grade 3 hepatotoxicity developed after favipiravir.Management & outcome: The acute viral hepatitis panel and autoimmune liver disease panel were negative. The ultrasound of the abdomen was unremarkable for any hepatobiliary pathology. The all viral and hepatobiliary possible etiological factors were ruled out. The patient's liver enzymes increased just after (12 hours later) the initiation of favipiravir, and we diagnosed toxic hepatitis caused by favipiravir-methotrexate interaction. Therefore, methylprednisolone 1 mg/kg dose was started for a presumed diagnosis of toxic hepatitis. Hepatotoxicity completely regressed after favipiravir was discontinued. DISCUSSION: Favipiravir may inhibit methotrexate elimination by inhibiting aldehyde oxidase and its sequential use may cause hepatotoxicity in this case. The clinicians should keep in mind possible drug interactions while using new antiviral agents against SARS-CoV2 like favipiravir.

RESUMEN

INTRODUCTION: To evaluate biosimilar understanding and preference trends of medical oncologists in Turkey. METHODS: A survey consisting of 24 multiple-choice questions with checkbox answers was conducted among medical oncologists. The questionnaire was divided into five parts to some intentions: demographic characteristics, general knowledge about biosimilars, knowledge about local approval and reimbursement issues, individual preference trends, and ranking the knowledge of their own. All answers were analyzed as whole cohort, specialists and fellows. RESULTS: Fellows (n = 47) consisted 42%, and academic clinicians (n = 37) consisted 35% of the participants. In the whole cohort, the overall rate of correct answers was 55.1% in the general knowledge about the biosimilars part, and 26.7% in the local approval and reimbursement issues part. At all, 57.7% of the participants declared that they object to switch from a reference product to a biosimilar product. The rate of those who defined themselves as extremely knowledgeable decreased from 8.1% to 2.7% in the whole cohort at the end of the survey. CONCLUSION: The need for more accurate and clarified local regulations and education emerging in the biotechnology era must be met.

RESUMEN

Silymarin (Silybum marianum) has some protective effects against drug toxicity (cisplatin, acetaminophen, adriamycin, gentamicin etc.). Colistin is a strong antimicrobial, which is frequently used in the treatment of resistant gram-negative bacterial infections in recent years although it has nephrotoxic potential. This study was aimed to determine the role of silymarin against colistin-induced acute nephrotoxicity (CIN). Rats were randomly divided into four groups. The control group was treated with tap water whereas groups 2 and 3 received silymarin (orally, 100 mg/kg/day) and colistin (intraperitoneally, 750.000 IU/kg/day) for seven days, respectively. Group 4 received both 750,000 IU/kg/day colistin and 100 mg/kg/day silymarin for seven days. After euthanasia, histopathological and biochemical examinations were completed for the kidney tissue specimens and blood samples. All parameters of the control and silymarin groups were similar. Severe weight loss was seen in the groups receiving colistin (groups 3 and 4). Silymarin significantly increased glutathione peroxidase and superoxide dismutase levels when administered with colistin in group 4 only. Acute tubular injury, tubular necrosis, meduller congestion, interstitial inflammation and apoptotic indices of colistin group were significantly higher than the control group. The administration of colistin with silymarin (group 4) was able to make some improvements in tubular necrosis and significant increase in antioxidant capacity. Silymarin increased antioxidant enzyme activity only when used in combination with colistin. The effects of silymarin may become more pronounced when used at higher doses or with a longer duration of treatment and may prevent nephrotoxicity.

RESUMEN

BACKGROUND: The aim of our study was to compare the efficacy and the safety of the FLOT and the modified DCF (mDCF) regimens in patients with metastatic gastric (GC) and gastroesophageal junction (GEJ) adenocarcinoma as first-line treatment. METHODS: The medical records of 72 patients were retrospectively reviewed. Survivals and hematological adverse events of the patients were examined. Factors affecting survivals were analyzed in univariate analysis. A multivariate analysis was performed with the factors contributing to survivals in univariate analysis. RESULTS: The median PFS (mPFS) was 10.1 months (95% CI, 6.8-13.4) in the FLOT arm (n = 33) and 7.4 months (95% CI, 9.1-21.6) in the mDCF arm (n = 39) (p = 0.041). The median OS (mOS) was 12.9 months (95% CI, 9.7-16.1) in the FLOT arm and 15.4 months (95% CI, 9.1-21.6) in the mDCF arm (p = 0.622). It was found that all grade neutropenia was 51.3% vs. 72.7% (p = 0.063), febrile neutropenia was 8.3% vs. 6.3% (p = 0.743), and thrombocytopenia was 48.7% vs. 51.5% (p = 0.813) in the FLOT and mDCF arms, respectively. Anemia was 59% in the FLOT arm and 100% in the mDCF arm (p < 0.001). Grade 3-4 anemia was 7.7% in the FLOT arm and 24.2% in the mDCF arm (p = 0.052). DISCUSSION: It was shown that the mPFS was significantly increased in the FLOT arm compared to the mDCF arm as the first-line treatment in patients with metastatic GC and GEJC. Hematological adverse events were more favorable in the FLOT arm than in the mDCF arm.

RESUMEN

Aim: To evaluate the immunogenicity and safety of the CoronaVac vaccine in patients with cancer receiving active systemic therapy. Methods: This multicenter, prospective, observational study was conducted with 47 patients receiving active systemic therapy for cancer. CoronaVac was administered as two doses (3 µg/day) on days 0 and 28. Antibody level higher than 1 IU/ml was defined as 'immunogenicity.' Results: The immunogenicity rate was 63.8% (30/47) in the entire patient group, 59.5% (25/42) in those receiving at least one cytotoxic drug and 100% (five of five) in those receiving monoclonal antibody or immunotherapy alone. Age was an independent predictive factor for immunogenicity (odds ratio: 0.830; p = 0.043). Conclusion: More than half of cancer patients receiving active systemic therapy developed immunogenicity.

RESUMEN

PURPOSE: The study was aimed to evaluate the effect of uric acid (UA) on the 30-day mortality of patients admitted to the tertiary referral hospital with a complaint of febrile neutropenia (FEN). The secondary aim was to evaluate the use of combining serum UA levels with the Multinational Association for Supportive Care in Cancer (MASCC) risk score. METHODS: A retrospective study in which the MASCC score and serum UA levels were used to evaluate the mortality risk within 30 days among patients with FEN. RESULTS: A total of 118 FEN episodes were included in the study and 17 (14%) of these patients died. While this rate is 23% in the high-risk group according to the MASCC score, it is 7% in the low-risk group (p = 0.011). In multivariate analysis of the parameters that significantly affect the 30-day FEN mortality, MASCC risk score (OR, 4.28; CI 95% 1.19-15.39, p = 0.013) and having a level of serum UA > 7 mg/dL (OR, 4.46; CI 95% 1.19-15.38, p = 0.032) was significantly increased the risk of in 30-day mortality of FEN. The rate of 30-day mortality of FEN was 0% in patients with a low MASCC risk score and UA level compared with 50% in the high MASCC risk score and high UA level group, and the difference was statistically significant (p < 0.001). CONCLUSION: Increased level of UA at the time of FEN diagnosis was independently associated with an increased rate of 30-day mortality of FEN. The combination of the MASCC risk score and serum UA level might thoroughly predict the 30-day mortality of FEN.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the effect of the serum albumin/globulin ratio (AGR) on the 30-day mortality of febrile neutropenia (FEN). The second aim of the study was to evaluate the effect of the combination of the AGR with the Multinational Association for Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) risk indexes on 30-day mortality of FEN. METHODS: A retrospective study evaluating the effect of serum AGR, MASCC and CISNE scores on 30-day FEN mortality. RESULTS: A total of 137 FEN episodes in 120 patients were included in this study. Nineteen patients (14%) died within the first 30 days of FEN episodes. The 30-day mortality rate was calculated as 4% in patients with high AGR and 23% in patients with low AGR (P = .002). According to the MASCC and CISNE risk scores, the mortality rates in low-risk patients were 8% and 6%, respectively, and in the high-risk group 22% and 29%, respectively (P = .024 vs P < .001). In the group of patients with MASCC <21 and CISNE ≥3, the 30-day mortality rate was 7%, when the AGR was >1.13, and in those with AGR ≤1.13 mortality rate increased to 50% (P = .012). CONCLUSION: A low AGR in a patient with FEN was found to be associated with an increased risk of 30-day mortality. Combining the AGR with MASCC and CISNE risk indexes might increase the predictive value of these scoring systems on 30-day mortality.
