130 Background: Tyrosine kinase inhibitors (TKI) are the most common oral drugs in cancer patients. Similarly, proton pump inhibitors (PPI) are commonly used to relieve dyspeptic symptoms in patients with cancer. However, gastric pH levels may affect the absorption of TKI through the gastrointestinal system. However, all TKIs do not have the same chemical structure, and the absorption rate of each TKI depends on their solubility in different gastric pH levels. Limited data is available about the clinical outcomes of concomitant use of PPI and regorafenib in patients with metastatic colorectal cancer (mCRC). We present here the results of the multicenter study following the initial results of our single-center experience. Methods: Patients with mCRC treated with regorafenib were included in this multicenter and retrospective study. Patients prescribed PPI after initiation of regorafenib were assigned to the PPI user group, and the remaining patients were assigned to the PPI non-user group. To exclude immortal time bias, the log-rank test was performed between PPI non-user and all patients. The primary outcome was overall survival (OS), and secondary outcomes were time to treatment failure (TTF) and adverse events (AEs) profile. Results: Two hundred and seventy-two patients from eight cancer centers were included in this study. Most patients were male (59.9%), had liver metastasis (62.1%), and received regorafenib in the third line (52.2%). The median age at the initiation of regorafenib was 60 years (interquartile range (IQR): 51-66)). Eastern Cooperative Oncology Group performance score was 0 or 1 in approximately three out of four patients. The rate of patients with K-RAS mutation was 46.7%. There were 131 (48.2%) and 141 (51.8%) in the PPI user and non-user groups, respectively. The most prescribed PPI was pantoprazole (40.4%). At a median 34.2 months follow-up, the median OS was 6.9 months (95% Confidence Interval (CI): 5.3-8.5) and 7.7 months (95% CI:6.6-8.8) in the PPI non-user and all patients, respectively. No statistical significance was observed between the groups (p = 0.913). The median TTF was 3.3 months (95% CI: 2.6-3.9) and 3.4 months (95% CI:2.9-4.0) in the PPI non-user and all patients, respectively. No statistical significance was observed between the groups (p = 0.651). In the time-dependent covariate Cox regression model, there was no difference between PPI user and non-user groups in OS and TTF (adjusted Hazard Ratio (aHR):0.96, 95% CI:0.74-1.24, p = 0.735 for OS; aHR:0.88, 0.68-1.14, p = 0.354 for TTF). The rates of all AEs were also similar in the PPI user and non-user groups (p = 0.628). Conclusions: To our knowledge, this was the first study evaluating the effect of concomitant use of PPI and regorafenib in patients with mCRC, and no adverse survival and safety outcome was observed with the concomitant use of PPI and regorafenib in those patients.

Crizotinib is a multikinase inhibitor, effective in non-small cell lung cancer (NSCLC) harboring mesenchymal-epidermal transition (MET) alterations. Although small prospective studies showed efficacy and safety of crizotinib in NSCLC with MET alterations, there is limited real-life data. Aim of this study is to investigate real-life efficacy and safety of crizotinib in patients with advanced NSCLC harboring MET alterations. This was a retrospective, multicenter (17 centers) study of Turkish Oncology Group. Patients' demographic, histological data, treatment, response rates, survival outcomes, and toxicity data were collected. Outcomes were presented for the study population and compared between MET alteration types. Total of 62 patients were included with a median age of 58.5 (range, 26-78). Major histological type was adenocarcinoma, and 3 patients (4.8%) had sarcomatoid component. The most common MET analyzing method was next generation sequencing (90.3%). MET amplification and mutation frequencies were 53.2% (n?=?33) and 46.8% (n?=?29), respectively. Overall response rate and disease control rate were 56.5% and 74.2% in whole study population, respectively. Median progression free survival (PFS) was 7.2 months (95% confidence interval [CI]: 3.8-10.5), and median overall survival (OS) was 18.7 months (95% CI: 13.7-23.7), regardless of treatment line. Median PFS was 6.1 months (95% CI: 5.6-6.4) for patients with MET amplification, whereas 14.3 months (95% CI: 6.7-21.7) for patients with MET mutation (P?=?.217). Median PFS was significantly longer in patients who have never smoked (P?=?.040), have good performance score (P?.001), and responded to the treatment (P?

Thiols are the organic compounds of the antioxidant system. There is limited data in the literature concerning chemotherapy (CT) in cancer and thiol balance. In this study, we aimed to evaluate the possible changes of thiol/disulfide levels with the recurrent CT cycles and type of cancer.The 40 healthy individuals and 40 patients who had been newly diagnosed with early-stage breast, ovary and endometrium cancer receiving adjuvant CT. Blood samples were taken from all patients three times as basal and after the first and second CT sessions.We compared preadjuvant treatment levels of thiol and disulfide parameters in the patients group with the control group. The median of native thiol and total thiol was found to be higher in the control group than in the study group (P0.001). In addition, disulfide/native thiol and disulfide/total thiol rates were found to be higher in the patient group (P = 0.001). When we look at the comparison before and after CT in the patient group, disulfide/native thiol and disulfide/total thiol rates, which represent increased oxidative stress (OS) levels were found to be higher after CT than before CT measurement (P0.016).This is the first study, which has researched the relationship between cancer type and thiol compounds and changes of thiol compounds during CT therapy, by using the method designed by Erel and Neşelioğlu. In this study, we found that pre-CT thiol disulfide balance in cancer patients shifted toward disulfide direction and OS levels may increase after repetitive CT sessions.

The new second-generation tyrosine kinase inhibitors (TKIs) have superior survival outcome and worse toxicity profile when compared with first-generation TKIs according to the results of clinical trials. However, there are limited studies that investigate the efficacy and safety of the new generation TKIs in real-world patients. Thus, we aimed to compare the efficacy and safety of the afatinib, an irreversible inhibitor of ErbB family receptor, and first-generation TKIs in real-world patients. We included advanced nonsmall cell lung cancer (NSCLC) patients who had EGFR exon 19del mutation and treated with afatinib or first-generation TKIs as upfront treatment between 2016 and 2020. All patient's information was collected retrospectively. The study cohort was divided as afatinib arm and erlotinib/gefitinib arm. A total of 283 patients at the 24 oncology centers were included. The 89 and 193 of whom were treated with afatinib and erlotinib/gefitinib, respectively. After 12.9 months (mo) of follow-up, the median PFS was statistically longer in the afatinib arm than erlotinib/gefitinib arm (19.3 mo vs. 11.9 mo, p: 0.046) and the survival advantage was more profound in younger patients (

Background Pan-immune-inflammation value (PIV) is an easily accessible immune marker based on peripheral blood to estimate prognosis in patients with cancer. This study evaluates the prognostic value of PIV in patients with metastatic renal cell carcinoma (mRCC) treated with nivolumab. Methods In this retrospective cohort study, patients with mRCC treated with nivolumab in the second line and beyond were selected from the Turkish Oncology Group Kidney Cancer Consortium (TKCC) database. PIV was calculated by using the following formula: neutrophil (103/mm3) x monocyte (103/mm3) x platelet (103/mm3) / lymphocyte (103/mm3). Results A total of 152 patients with mRCC were included in this study. According to cut-off value for PIV, 77 (50.7%) and 75 (49.3%) patients fell into PIV-low (\(\le\)372) and PIV-high (>372) groups, respectively. In multivariate analysis, PIV-high (HR:1.64, 95% CI: 1.04–2.58, p = 0.033 for overall survival (OS); HR:1.55, 95% CI: 1.02–2.38, p = 0.042 for progression-free survival (PFS)) was independent risk factor for OS and PFS after adjusting for confounding variables such as performance score, the International mRCC Database Consortium (IMDC) risk score, and liver metastasis. Conclusion This study established that pre-treatment PIV might be a prognostic biomarker in patients with mRCC treated with nivolumab in the second line and beyond.

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.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.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.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.

This study aims to investigate the prognostic value of the systemic immune-inflammation index (SII)and its impact on survival in patients with metastatic renal cell carcinoma (mRCC). A total of 706patients with mRCC treated with tyrosine kinase inhibitors (TKIs)between January 2007 and June 2020 (i.e., sunitinib, pazopanib) were included in this study. SII was calculated in 621 patients with the following formula:[neutrophil (cellsx109/L) x platelet (cellsx109/L)] / lymphocyte (cellsx109/L).All patients were classified into SII-high and SII-low groups based on the cut-off value of SII at 756, which was the median SII level of our study group. The minimal follow-up duration was 10 months in all cohorts. The median age of patients was 60 (interquartile range (IQR):53–67) years. Three out of four patients were male. The majority of patients (85.7%) had clear cell histology, and sarcomatoid differentiation was observed in 16.9% of all patients. There were 311 and 310 patients in the SII-low and SII-high groups, respectively. In general, baseline characteristics were similar in each group. However, the rate of patients treated with sunitinib (63.3% vs. 49.0%, p p p p p = 0.026) metastasis, and those with Eastern Cooperative Oncology Group(ECOG) 2–4 performance score (28.1% vs.17.7%, p = 0.002) were more common in the SII-high group than in the SII-low group. The median overall survival (OS) was longer in the SII-low group than in the SII-high group (34.6 months vs. 14.5 months, p p p = 0.01) and PFS (HR:1.60, 95% CI:1.24–2.05, p

Purpose: Taxane-containing combinations are recommended for the first-line therapy of advanced gastric cancer. It is not known which chemotherapy regimen is the best with trastuzumab for HER2-positive patients. The aim of this study was to compare taxane-containing intensified chemotherapy versus standard chemotherapy in combination with trastuzumab in the first-line treatment of HER2-positive advanced gastric adenocarcinoma. Methods: This study is a retrospective multicenter study of the Turkish Oncology Group. A total of 130 HER2-positive patients with inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma being given chemotherapy plus trastuzumab as the first-line treatment were included from 16 different oncology centers. Trastuzumab combination with intensified chemotherapy including taxane or standard chemotherapy was compared in terms of progression-free survival (PFS), overall survival (OS), and toxicity. Results: There were 108 patients in the standard and 22 patients in the intensified chemotherapy group. PFS of the standard and intensified group were 5.6 months (95% confidence interval [CI] 4.8–6.4) and 5.3 months (95% CI 2.6–8), respectively ( p = 0.70). OS of the standard and intensified group were 11.1 months (95% CI 8.3–13.9) and 15.2 months (95% CI 12.7–17.7), respectively ( p = 0.03). Repeated analysis excluding patients given any previous therapy revealed similar results. The intensified group had more fever and febrile neutropenia. Conclusion: Trastuzumab combination with intensified chemotherapy provides better OS in first-line treatment of HER2-positive advanced gastric cancer. Further large-scale studies should be performed in HER2-positive patients.

Lung cancer is the most common cancer type and the leading cause of cancer-related mortality worldwide. The positivity rate of the anaplastic lymphoma kinase (ALK) mutation in non-small cell lung cancer (NSCLC) patients has been reported as 3-7%. This study aimed to investigate the pathological, clinical and demographic characteristics of ALK-mutant NSCLC patients who received first-line alectinib as a tyrosine kinase inhibitor in two different centers.The study was performed at the Medical Oncology Departments of Ankara City Hospital and Atatürk Chest Diseases and Thoracic Surgery Training and Research Hospital. Patients diagnosed with ALK-mutant NSCLC and received alectinib treatment as a first-line tyrosine kinase inhibitor were enrolled to study and retrospectively analyzed.A total of 38 patients (15 males, 23 females) were included in the study. Median age was 56.5. 55.3% of the patients were non-smokers. All of the patients had adenocarcinoma histology. Thirty-four patients (89.5%) were metastatic. Brain metastasis was detected in 44.7% of the patients. Thirty-three patients (86.8%) were using alectinib in first-line treatment. The remaining five patients were seen to have received at least one course of chemotherapy before. The objective response rate was 78.9% with alectinib treatment. The percentage of the patients who experienced at least one side effect was 34.2% and serious side effects were 7.9%. After median 9.5 months follow-up, median progression-free survival (PFS) was not achieved. 24-month PFS was 67% and 24-month overall survival was 84%.Our results were compatible with previous studies in terms of the clinical, pathological and demographic features of the patients with ALK mutation. We observed that the majority of patients were non-smokers, relatively young, and female patients. The objective response rate and survival results were similar with phase 3 studies.

Recently, neoadjuvant treatment approach has gained importance in locally advanced HER-2 positive breast cancer. Adding pertuzumab increases pathological complete response (pCR). In this study, we aimed to examine the clinicopathologic features that predict the pCR in patients receiving neoadjuvant pertuzumab, trastuzumab, and chemotherapy in locally advanced HER2 positive breast cancer.Locally advanced HER2 positive breast cancer patients who were followed up in 4 different oncology centers and received 4 cycles of pertuzumab, trastuzumab and taxane were retrospectively evaluated. A total of 58 (92%) patients received anthracycline chemotherapy before combination of dual her-2 blockade and taxanes. Fisher's and chi-square tests were used for nominal variables and numeric data analyses.A total of 63 female patients were included in the study. Their median age was 46 years (21-75) and 40 (63.5%) patients were premenopausal. Median tumor size was 25 mm (2-70) and there were 22 (34.9%) patients with Stage 3a. pCR was 66% and 75% in the whole group and in the hormone negative group, respectively. Statistically significant increase was found in pCR in patients with grade 3 tumors and cerbB2 with 3+ immunohistochemical staining. No relationship was found between pCR and age at diagnosis, menopausal status, tumor infiltrating lymphocyte, dose-dense anthracycline, Ki67≥40, body mass index (BMI) ≥ 30 kg/m2 and accompanying DCIS.Four cycles of pertuzumab, trastuzumab and taxane after neoadjuvant anthracycline for locally advanced HER2 breast cancer are associated with increased pCR in patients with grade 3 tumors and high cerbB2 expression.

WOS:000617829700001 PMID: 33586012 Purpose We aim to compare the efficiency and toxicity of three different 5-fluorouracil (5-FU) administration types in 5-FU, leucovorin, and oxaliplatin (FOLFOX) combination treatment for adjuvant therapy in colorectal cancer (CRC). Methods Five hundred and seventy patients with stage III colorectal carcinoma who received different FOLFOX regimens after curative resection were included. Patients were divided into three groups as FOLFOX-4, modified FOLFOX-6 (mFOLFOX-6), and mFOLFOX-4 for comparison of toxicity and disease-free survival (DFS) and overall survival (OS) times. Results Three-year DFS rates for FOLFOX-4, mFOLFOX-6, and mFOLFOX-4 groups were 65%, 72%, and 72%, respectively. Five-year OS rates for FOLFOX-4, mFOLFOX-6, and mFOLFOX-4 groups were 69%, 75%, and 67%, respectively. There was no statistically significant difference between the three treatment groups in terms of DFS and OS (p = 0.079, and p = 0.147, respectively). Among grade 1-2 adverse events (AE), thrombocytopenia, neuropathy, and stomatitis were more common in the mFOLFOX-6-treated group. The frequency of grade 1-2 nausea and vomiting were similar in mFOLFOX-6 (36.3% and 24%, respectively) and mFOLFOX-4 (32.4% and 24.7%, respectively) groups but were higher than that in the FOLFOX-4 (19.5% and 11.3%, respectively) group. Among the most common grade 3-4 AE, neutropenia (53.4%, 9%, and 13.5%, respectively) and diarrhea (10.5%, 2.2%, and 2.4, respectively) were more common in FOLFOX-4. The rate of anemia and febrile neutropenia was similar in treatment groups (p = 0.063, and p = 0.210, respectively). Conclusion In the adjuvant treatment of stage III CRC patients, three different 5-FU administration types in FOLFOX combination treatment can be used with similar efficiency and manageable toxicity.

Purpose: In the ToGA trial for HER2-positive advanced gastric cancer, cisplatin plus fluoropyrimidine was given for 6 cycles; trastuzumab was given until disease progression. However, there is a lack of real-life data about trastuzumab maintenance after 6 cycle chemotherapy. This study aims to present real-life data of trastuzumab ± capecitabine maintenance after 6 cycles of platinum, fluoropyrimidine, and trastuzumab in non-progressive patients. Methods: This is a retrospective multicenter study of the Turkish Oncology Group. A total of 35 HER2-positive, inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma patients being non-progressive at the end of 6 cycle chemotherapy and being given trastuzumab ± capecitabine as maintenance treatment were included from sixteen oncology centers. Baseline characteristics, objective tumor responses, progression free and overall survival data, and toxicities were determined. Results: About 68% of the patients were given CF, and 32% were given FOLFOX with trastuzumab as the first-line treatment. The best response in 6 cycle chemotherapy was complete 8 (22%), partial 24 (68%), and stable disease 3 (8%). All patients had trastuzumab maintenance (median cycle 13; range 7–51), and 49% of the patients had capecitabine with trastuzumab (median capecitabine cycle 6; range 2–30). The median PFS of the patients was 12.0 months (95% CI 10.3–13.7), and median OS was 17.4 months (95% CI 15.2–19.5). There were 2 patients with grade 1 cardiotoxicity. Conclusion: Trastuzumab maintenance ± capecitabine after 6 cycles of trastuzumab plus combined chemotherapy treatment revealed efficacy and safety in non-progressive HER2-positive advanced gastric cancer. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.

Introduction: Osimertinib, an irreversible third-generation EGFR-TKI, is the standard of care for second-line treatment of T790M-mutant advanced NSCLC patients whose progressed after first-line EGFR-TKI therapy. In this multicenter study, we aimed to determine the real-life efficacy and safety of Osimertinib in pretreated advanced NSCLC patients with T790M mutation.Materials and Methods: This retrospective trial included advanced T790M-mutant pretreated NSCLC patients who received Osimertinib from 24 different centers in Turkey. Primary endpoint was time-to-treatment discontinuation (TTD). Secondary endpoints were objective response rate (ORR), overall survival (OS), and safety.Results: Of 163 patients 68.7% had EGFR exon 19 deletion and 22.7% had exon 21 L858R mutation. Osimertinib was given as second-line treatment in 96 patients (58.9%) and third-line in 48 patients (29.4%). After median of 13 months disease follow-up, median TTD was 21.6 months with an 82.2% ORR. Estimated median OS was 32.1 months. Grade 3-4 adverse events were seen in 11.7% of the patients. Conclusion: Osimertinib is a highly effective option in second or third-line treatment of NSCLC patients with T790M mutation, with a favorable safety profile.

Background: Immunotherapy improves overall survival (OS) in the second and later lines of renal cell carcinoma (RCC) treatment. Recent studies have suggested that antibiotic (ATB) use either shortly before or after the start of immunotherapy could lead to decreased OS. Herein, we evaluate the impact of ATB use on OS in RCC patients treated with nivolumab in a multi-center cohort from Turkey. Methods: The data of 93 metastatic RCC patients treated with nivolumab in the second line or later were retrospectively collected from 6 oncology centers. Previous treatments, sites of metastases, International Metastatic RCC Database Consortium risk classification, and ATB use in the three months before (-3) or three months after (+3) the start of immunotherapy were recorded together with survival data. The association of clinical factors with OS and progression-free survival (PFS) was analyzed with univariate and multivariable analyses. Results: The median age was 61 (interquartile range 54-67), and 76.3% of the patients were male. The median OS of the cohort was 23.75 ± 4.41, and the PFS was 8.44 ± 1.61 months. Thirty-one (33.3%) patients used ATBs in the 3 months before (-3) or 3 months after (+3) nivolumab initiation. In the multivariable analyses, ATB exposure (HR: 2.306, 95% confidence interval [CI]: 1.155-4.601, P = 0.018) and the presence of brain metastases at the baseline (HR: 2.608, 95% CI: 1.200-5.666, P = 0.015) had a statistically significant association with OS, while ATB exposure was the only statistically significant parameter associated with PFS (HR: 2.238, 95% CI: 1.284-3.900, P = 0.004). Conclusion: In our study, patients with ATB exposure in the 3 months before or 3 months after the start of immunotherapy had shorter OS. Our findings further support meticulous risk–benefit assessments of prescribing ATBs for patients who are either receiving or are expected to receive immunotherapy. WOS:000723830400020 34130864 Q3

Purpose Anaplastic lymphoma kinase (ALK) gene rearrangement exists in approximately 3-7% of non-small cell lung cancer (NSCLC) and more than 15% split or isolated red signals among 50 tumor nuclei scored in the FISH analysis defines as ALK-positive. The previous studies showed that the high EGFR mutational load related to better outcomes in EGFR mutant NSCLC. Therefore, we aimed to investigate the effect of the ALK break-apart ratio on treatment outcome in metastatic ALK-positive NSCLC. Methods The patients (pts) who ALK-positive and treated with crizotinib were retrospectively enrolled. The 30%, 40%, 50%, 60%, and 70% break-apart ratios were determined as a threshold value, and each of these was evaluated separately. Based on the results of these analyses, we detected the optimal threshold value and also performed further investigations. Results A total of 70 patients were enrolled in the study. The most significant decrease in the risk of the progression or death was detected at the 50% threshold value and it was accepted as the optimal threshold. The median PFS was 17.9 vs. 7.06 months (mo) in the pts with high ALK rearrangement than low (HR: 0.43, 95% CI 0.24-0.76, p 0.004). The median OS was also significant longer in high ALK rearrange group (44.6 mo vs. 16.8 mo; HR: 0.37, 95% Cl 0.1883-0.7315; p 0.004). The intracranial progression during crizotinib treatment was significantly frequent in the pts with high ALK rearrangement (62.5-32.5%, P 0.039) Discussion In this study, we found that the high break-apart ratio can predict the extent of benefit from targeted therapy in ALK-positive NSCLC patients. Based on the results of this study, the percentage of the ALK rearrangement can be used to predict treatment outcome and to choose the optimal targeted agent in the treatment of metastatic ALK-positive NSCLC.

Aims: The addition of aflibercept to the fluorouracil and irinotecan (FOLFIRI) regimen significantly improved clinical outcomes in patients with metastatic colorectal cancer (CRC) previously treated with oxaliplatin. We aimed to investigate the efficacy and safety of second-line FOLFIRI and aflibercept combination in patients with metastatic CRC in real-life experience. Materials and Methods: Four hundred and thirty-three patients who treated with FOLFIRI and aflibercept in the second-line were included in the study. The clinical and pathological features of the patients were recorded retrospectively. Survival (overall and progression-free survival [PFS]), response rates, and safety data were analyzed. Results: The median age was 61. Majority of patients (87.5%) received first-line bevacizumab and 10.1% of patients received anti-epidermal growth factor receptor agents. About 80% of patients had KRAS, 18.6% of patients had NRAS, and 6.4% of patients had BRAF mutations. The median OS was 11.6 months (95% confidence interval [CI], 10.6-12.6) and the median PFS was 6 months (95% CI, 5.5-6.5). About 4.6% of patients had complete response and 30.6% of patients had partial response as best tumor response. Grade 1-2 toxicities were seen in 33.4% of patients, while grade 3-4 toxicities were recorded in 27% of patients. Eight patients (2%) died due to treatment toxicity. Conclusions: Overall and PFS were similar in routine clinical practice compared to phase III pivotal VELOUR trial. However, response rates were found to be higher. It was observed that there were fewer adverse events compared to the VELOUR trial. © 2022 Authors. All rights reserved.
