RESUMEN
PURPOSE: In advanced breast cancer, endocrine therapy is preferred in the absence of visceral crisis. Cyclin-dependent kinase inhibitors (CDKi) are the gold standards. The selection of subsequent treatments after CDKi treatment is still controversial, and the efficacy of everolimus (EVE) combinations is unknown. In this study, we aimed to investigate the efficacy of EVE after CDKi administration in real-life experiences. METHOD: The study received data from 208 patients from 26 cancer centers. Demographic and histologic features, diagnosis, progression, last visit dates, and toxicities were recorded. This study was a retrospective case series. RESULTS: One hundred and seven patients received palbociclib, while 101 patients received ribociclib as a CDKi. The overall response and disease control rates of EVE combinations were 60% and 88%, respectively. In univariate analysis, the absence of liver metastasis, age > 40 years, better type of response, and immediate treatment after CDKi were related to increased progression-free survival. Liver metastasis and response type were significantly associated with overall survival. In the multivariate analysis, response remained significant in terms of progression-free survival, while response type, liver metastatic disease, and hematologic toxicity were prognostic in terms of overall survival. CONCLUSION: This study provides evidence of the benefits of EVE combinations after CDKi treatment. EVE combinations may be more appropriate for patients with non-liver metastasis, and the first treatment response shows the benefit of treatment. In addition, immediate treatment after CDKi treatment is more beneficial than later lines of treatment.
RESUMEN
INTRODUCTION: We compared the efficacy of first-generation granisetron and second-generation palonosetron in triplet anti-emetic prophylaxis in patients with non-small cell lung cancer (NSCLC) receiving cisplatin-based high emetogenic chemotherapy (HEC). METHODS: This prospective, multicenter, non-randomized, observational study was conducted between June 2018 and December 2021. Patients diagnosed with NSCLC who received triplet anti-emetic prophylactic treatment with aprepitant and dexamethasone plus granisetron or palonosetron before the first cycle of chemotherapy were included in the study. At the end of the first week after chemotherapy, the emesis scale was applied to the patients during the outpatient control. The primary endpoint was complete response (CR) and total control (TC). RESULTS: One hundred twenty-one patients were included in the study. Sixty-one patients were in the granisetron group and 60 patients were in the palonosetron group. CR was higher with granisetron in the acute phase (70.5% vs. 58.3%, p = 0.16; respectively) and higher with palonosetron in the delayed phase (61.7% vs. 55.7%, p = 0.5; respectively), although not statistically significant. The TC rates were also not significantly different between the groups (54.1% vs.57.6%, p = 0.69). CONCLUSIONS: There was no significant difference between granisetron and palonosetron in both acute and delayed control of emesis in NSCLC patients receiving cisplatin-based HEC.
RESUMEN
PURPOSE: This study evaluated the efficacy and safety of everolimus (EVE) plus exemestane (EXE) in hormone-receptor positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) metastatic breast cancer (MBC) patients in real-life settings. METHODS: Overall, 204 HR+, HER2- MBC patients treated with EVE + EXE after progressing following prior endocrine treatment were included. Overall survival (OS) and progression-free survival (PFS) and safety data were analyzed. RESULTS: The objective response rate, median PFS, and median OS were 33.4%, 8.9 months, and 23.4 months, respectively. Multivariate analysis revealed that negative progesterone receptor status was a significant determinant of poor treatment response (p = 0.035) and PFS (p = 0.024). The presence of bone-only metastasis was associated with better treatment response (p = 0.002), PFS (p < 0.001), and OS (p = 0.001). CONCLUSION: We confirmed the favorable efficacy and safety profile of EVE + EXE for HR+, HER - MBC patients.

AIM: The aim of this study is to evaluate the efficacy and toxicity of trastuzumab emtansine (T-DM1) in cases with metastatic breast cancer (mBC) in different lines of treatment. METHOD: Retrospective analysis of T-DM1 results of human epidermal growth factor receptor 2 (Her2) positive 414 cases with mBC from 31 centers in Turkey. FINDINGS: Except 2, all of the cases were female with a median age of 47. T-DM1 had been used as second-line therapy in 37.7% of the cases and the median number of T-DM1 cycles was 9. Progression-free survival (PFS) and overall survival (OS) times were different according to the line of treatment. The median OS was found as 43, 41, 46, 23 and 17 months for 1st, 2nd, 3rd, 4th and 5th line, respectively (p = 0.032) while the median PFS was found as 37, 12, 8, 8 and 8 months, respectively (p = 0.0001). Treatment was well tolerated by the patients. The most common grade 3-4 adverse effects were thrombocytopenia (2.7%) and increased serum gamma-glutamyl transferase (2%). DISCUSSION: The best of our knowledge this is the largest real-life experience about the safety and efficacy of T-DM1 use in cases with mBC after progression of Her2 targeted treatment. This study suggests and supports that T-DM1 is more effective in earlier lines of treatment and is a reliable option for mBC.

OBJECTIVE: Natural disasters such as earthquakes can have a significant impact on cancer treatment and care. The objective of the study was to evaluate the psychological effect of the earthquake on survivor cancer patients compared to regular cancer patients. METHODS: Cancer patients who were evacuated from earthquake sites and referred for the continuation of their treatment, as well as regular resident patients were included in the study. The resident cancer patients were compared with the study population as a control group. DASS-21 forms were filled based on patients' declarations. RESULTS: Forty-six patients were earthquake survivors and 55 were resident cancer patients. Stress scores were significantly higher in earthquake survivors (P = 0.021). In contrast, there was no difference in stratified groups due to DASS-21 categorization in stress scores while depression and anxiety subgroups had significant differences (P = 0.012; P < 0.001). Also, women significantly had a worse outcome in the depression and anxiety categories (P = 0.028; P = 0.021) while no difference was observed in men. CONCLUSION: Recent earthquakes in Turkey had psychological negative effects on oncology patients. The increased stress, depression, and anxiety levels were observed in earthquake survivors who were evacuated from the disaster zone and compared to the control group.

BACKGROUND: The discovery of the epidermal growth factor receptor (EGFR) mutation, especially in adenocarcinoma, has led to a major change in the treatment of non-small-cell lung cancer (NSCLC). This study investigated the relationship between the EGFR mutation status and the carcinoembryonic antigen (CEA) levels at the time of diagnosis. MATERIALS AND METHODS: A total of 102 patients with EGFR mutation and tested CEA levels were recruited for this study. Of the patients, 24 were EGFR mutants (23.5%), while 78 patients (76.5%) did not harbor any EGFR mutations. RESULTS: The CEA levels did not differ across groups. Additionally, the CEA levels were analyzed between female and male patients separately due to EGFR mutations; no difference was observed. When the CEA levels were categorized as positive or negative based on different cut-off values, such as 5 and 10 ng/ml, no statistical difference was found between groups. CONCLUSION: In this study, no relationship between EGFR mutation and pre-treatment CEA levels was observed. Despite positive trials having shown a predictive value of CEA levels for EGFR mutation, more clinical trials are needed to elucidate the racial, clinical, and pathological differences of the study populations. Most studies have been located in the Far East, but new trials in Caucasian, African, and Hispanic populations are still lacking.

Background Breast cancer is the most common cancer in women. Body composition and inflammatory markers are increasingly important for predicting cancer prognosis. The Cancer Cachexia Index (CXI) and the modified Glasgow Prognostic Score (GPS) are two new markers evaluating prognosis in cancer. In this study, we evaluated the utility of the CXI and the modified GPS in young patients with breast cancer. Methods Eighty patients diagnosed between 2012 and 2023 were included in the study. The following information was recorded: patient features, pathological subtype, estrogen receptor and human epidermal growth factor receptor-2 (HER-2) status, disease stage, therapies, disease recurrence, and last control or death date. The CXI and the modified GPS were calculated using clinical data, including skeletal muscle index, albumin, C-reactive protein, and neutrophil-to-lymphocyte ratio. Results There were no differences in overall survival with respect to the CXI in the study population (p=0.96). Only stage 4 patients showed statistically significant survival differences according to the CXI (p=0.046). Although the median survival time was not reached for the modified GPS groups, there was a statistical overall survival difference favoring the negative group (p=0.017). No significant differences were observed in disease-free survival due to the CXI (p=0.128). In multivariate analysis, no factors, including the modified GPS and the CXI, influenced overall survival. There was a significant effect of the modified GPS and body mass index on recurrence (p=0.037; p=0.034). The CXI had a non-significant marginal p-value (p=0.074). Conclusion Our study showed that the modified GPS may be related to disease-free survival and overall survival, whereas the CXI has a more prominent prognostic effect on overall survival in advanced-stage breast cancers. In early-stage and young patients, optimization of risk scores is lacking.
RESUMEN
INTRODUCTION: Adrenocortical carcinoma (ACC) is a rare yet highly malignant tumor associated with significant morbidity and mortality. This study aims to delineate the clinical features, survival patterns, and treatment modalities of ACC, providing insights into the disease's prognosis. MATERIALS AND METHODS: A retrospective analysis of 157 ACC patients was performed to assess treatment methodologies, demographic patterns, pathological and clinical attributes, and laboratory results. The data were extracted from the hospital's database. Survival analyses were conducted using the Kaplan-Meier method, with univariate and multivariate analyses being performed through the log-rank test and Cox regression analyses. RESULTS: The median age was 45, and 89.4% had symptoms at the time of diagnosis. The median tumor size was 12 cm. A total of 117 (79.6%) patients underwent surgery. A positive surgical border was detected in 26 (24.1%) patients. Adjuvant therapy was administered to 44.4% of patients. The median overall survival for the entire cohort was 44.3 months. Median OS was found to be 87.3 months (95% confidence interval [CI] 74.4-100.2) in stage 2, 25.8 (95% CI 6.5-45.1) months in stage 3, and 13.3 (95% CI 7.0-19.6) months in stage 4 disease. Cox regression analysis identified age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as significant factors associated with survival in patients with nonmetastatic disease. In metastatic disease, only patients who underwent surgery exhibited significantly improved overall survival in univariate analyses. CONCLUSION: ACC is an uncommon tumor with a generally poor prognosis. Understanding the defining prognostic factors in both localized and metastatic diseases is vital. This study underscores age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as key prognostic determinants for localized disease, offering critical insights into the complexities of ACC management and potential avenues for targeted therapeutic interventions.

The only phase 3 study on the effectiveness of CDK 4-6 inhibitors in first-line treatment in premenopausal patients with hormone receptor (HR) positive, HER2 negative metastatic breast cancer is the MONALEESA-7 study, and data on the effectiveness of palbociclib is limited. Data are also limited regarding the effectiveness of CDK 4-6 inhibitors in patients whose dose was reduced due to neutropenia, the most common side effect of CDK 4-6 inhibitors. In our study, we aimed to evaluate the effectiveness of palbociclib and ribociclib in first-line treatment in patients with premenopausal metastatic breast cancer and the effect of dose reduction due to neutropenia on progression-free survival. Our study is a multicenter, retrospective study, and factors affecting progression-free survival (PFS) were examined in patients diagnosed with metastatic premenopausal breast cancer from 29 different centers and receiving combination therapy containing palbociclib or ribociclib in the metastatic stage. 319 patients were included in the study. The mPFS for patients treated with palbociclib was 26.83 months, and for those receiving ribociclib, the mPFS was 29.86 months (p = 0.924). mPFS was 32.00 months in patients who received a reduced dose, and mPFS was 25.96 months in patients who could take the initial dose, and there was no statistical difference (p = 0.238). Liver metastasis, using a fulvestrant together with a CDK 4-6 inhibitor, ECOG PS 1 was found to be a negative prognostic factor. No new adverse events were observed. In our study, we found PFS over 27 months in patients diagnosed with premenopausal breast cancer with CDK 4-6 inhibitors used in first-line treatment, similar to post-menopausal patients. We did not detect any difference between the effectiveness of the two CDK 4-6 inhibitors, and we showed that there was no decrease in the effectiveness of the CDK 4-6 inhibitor in patients whose dose was reduced due to neutropenia.
RESUMEN
BACKGROUND: The response of Renal Cell Cancer (RCC) to tyrosine kinase inhibitors (TKI) has been well established. Although these stratifications have been established for TKI response and prognosis, these parameters have recently been used to predict immunotherapy response in RCC. We aimed to use a combination of clinical parameters of International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk groups and metastatic sites at the time of diagnosis to predict the effectiveness of immune checkpoint inhibitors in malignant melanoma (MM). METHOD: In this cross-sectional study, we retrospectively analyzed the demographic information, metastatic sites, and IMDC risk group data. The blood parameters were included in the first cycle of nivolumab treatment. RESULTS: The OS was statistically different between the RCC and MM groups in terms of the IMDC. In univariate analysis of stage at diagnosis, CRP levels and bone and bone marrow metastases were confirmed to be prognostic factors in the MM population in terms of OS. Brain metastasis was a prognostic factor for RCC, whereas sex, line of treatment, LDH, bone, and splenic metastasis remained significant in patients with MM in terms of OS. Brain metastasis was prognostic in both cancer types in multivariate analysis in terms of PFS. In addition to brain metastasis, LDH levels and lung, liver, and splenic metastases also affect PFS in patients with MM undergoing nivolumab treatment. CONCLUSION: In our study, the IMDC was confirmed to be a prognostic factor for MM. The IMDC groups were similar, except for the favorable RCC and MM groups. Different metastatic sites were prognostic, similar to the IMDC risk group in the MM group.

INTRODUCTION: Although several clinical factors which show the benefit of adjuvant chemotherapy (AC) in early-stage colon cancer use for evaluating the risk of relapse, there is no consensus on which risk factors are more reliable. In this study, we evaluated both the utility of MSI and the daily practice of the Turkish oncologists in stage II and III colon cancer. MATERIAL AND METHOD: We conducted an online questionnaire which was consisting of twenty questions including the treatment choices and duration about stage II-III colon cancer depending on sidedness and risk factors for relapse. RESULTS: More than 65% of the oncologists declared the use of MSI testing in stage II colon cancer without considering any risk factors. In stage 3 colon cancer oncologists had an equal decision "to do or not to do" in MSI testing. More than 50% of the oncologists had preferred XELOX protocol in high-risk stage II (T4N0) colon cancer, while three out of four preferred observation in low-risk stage II (T3N0) patients without risk factors. Two-thirds of the oncologists had preferred 6 months of treatment in stage II colon cancer with at least one risk factor. CONCLUSION: Turkish oncologists participating to this trial had declared conflicting results about adjuvant treatment in early-stage colorectal cancer in their daily practice compared with the updated guidelines, especially, MSI evaluation utility in stage III colon cancers, adjuvant chemotherapy (AC) duration, and oxaliplatin adding to AC in elderly and stage II patients.

OBJECTIVE: To evaluate the prognostic role of pan immune-inflammation value (PIV) in young breast cancer patients. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Medical Oncology, Afyon University of Health Sciences, School of Medicine Hospital, Turkey, between January 2010 and December 2020. METHODOLOGY: Patients who were under the age of 40 years at the time of diagnosis were included. Patients' characteristics and disease parameters were recorded. PIV was calculated according to (neutrophil x platelet x monocyte/lymphocyte, i.e. NxPxM/L) formula. Since a cut-off value with max sensitivity and specificity could not be obtained with ROC analysis, the median value of PIV was used as cut-off value. The relationship between PIV and pathological parameters was evaluated by ROC curves. The Kaplan-Meier method was used for OS and the log-rank test was used to evaluate the survival differences between the two groups, according to the optimal cut-off point. RESULTS: Based on the PIV cut-off value of 121 (49.8%) patients were in the low PIV and 122 (50.2%) patients were in the high PIV group. The patients in the high PIV group had a statistically significantly more advanced AJCC stage, and were younger patients. In the survival analysis, it was observed that the survival was worse in the high PIV group but this difference did not reach statistical significance (p=0.112). CONCLUSION: Higher PIV levels at the time of diagnosis can be another prognostic marker. However, to clarify the PIV prognostic value, it needs to be validated in larger, multi-centre prospective clinical studies. Key Words: Breast cancer, Pan immune-inflammation value (PIV), Prognosis, Young women.

PURPOSE: The novel coronavirus (COVID-19) was defined in China, leading an outbreak, impacted the organization, and maintained cancer care. Although the alterations of cancer treatment maintenance were evaluated, the difference in physicians' side was not determined. In this survey study, we tried to assess the alteration of Turkish oncologists' daily practice. METHODS: An online survey was prepared via Google forms and sent to oncologists registered to the Turkish Society of Medical Oncology. One hundred twenty-eight oncologists answered the online survey. RESULTS: Twenty-three percent of the oncologists moved their facilities to another place in the hospital after the pandemic, which was resulted in nearly 90% of worse patient services. Seventy percent of the oncologists did not receive any duties on COVID-19 services after Turkey's first case. Thirty-one percent of the oncologists stated their oncology practice was disturbed by working in the COVID-19 services. Three oncologists accepted they were responsible for cross-infection to oncology patients. Eighty-five percent of the oncologists declared oncology practice was disturbed by the other specialists' assignment in COVID-19 services. The leading areas were general surgery, pulmonary diseases, and ENT, according to oncologists. Twenty-two percent of the oncologists needed to send their patients to other oncology clinics due to the COVID-19 pandemic. CONCLUSION: Although oncologists tolerated oncological patient management alterations, the prolonged pandemic situation may harm oncology practice via the loss of oncologists' motivation and incomplete multi-disciplinary patient management. There is a need for follow-up studies to evaluate the situation for the alternation in the COVID-19 pandemic.â.

PURPOSE: Colorectal cancer is the third leading diagnosis accounting for nearly 10% of all new cancers worldwide. The distinct features among BRAF mutant colorectal cancers make these tumor groups hard to treat for oncologists. The median overall survival (OS) of these types of cancers is reported to be 9 to 14 months. METHODS: The study was declared on the Turkish Oncology Study Group Conference and approved. The patients' data was received from the centers who confirmed to participate. The BRAF-mutated patients were included in the study. The demographic features (age, gender, etc.), type of mutation, tumor localizations, histology, microsatellite instability (MSI) status, metastasis patterns chemotherapeutic agents and progression, and death times were recorded. RESULTS: Thirty-nine patients were enrolled in the study. Sixteen patients had concurrent KRAS mutations, while 7 had NRAS mutations. Most of the patients received doublet chemotherapies in combination with anti-VEGF agents in the first and second line of the treatment. There was a significant difference in OS according to the stage which showed a decreased survival in stage IV patients at the time of diagnosis. Concurrent KRAS mutation resulted in increased OS. The median OS was 47 and 24 months favoring the KRAS mutant group. The patients whose primary tumor operated had better survival when compared with other patients. The median OS of the operated group was 47 months, while the non-operated group was 24 months. Liver metastasis was related to worse prognosis at the time of diagnosis in univariate analysis. CONCLUSION: In our study we found a high concurrent RAS mutation ratio in a BRAF mutant patient group which was different from prior studies. The concurrent mutations resulted in a favorable outcome in terms of OS which is also different from the current knowledge. More prospective studies are needed especially BRAF-mutated patient population and especially with concurrent RAS mutations.

Background: The synthesis of CDK4/6 inhibitors with endocrine treatment in two series of treatment has been widely accepted as the standard for patients with estrogen receptor-positive metastatic breast cancer. In spite of this, the activity of CDK4/6 inhibitors in patients with metastatic breast cancer who have progressed despite receiving multiple lines of treatment is not well understood. Aims: To report the activity and safety of a CDK4/6 inhibitor (palbociclib) in patients in whom at least three lines of treatment for ER+ metastatic breast cancer had failed. Study Design: Multicenter retrospective observational cohort study. Methods: In this retrospective observational cohort study, we included 43 patients who received palbociclib after at least three lines of systemic treatment for ER+/HER2− metastatic breast cancer. Results: The median progression-free survival in our population was 7 months (25th-75th percentile, 4-10), and the median overall survival was 11 months (25th-75th percentile, 6-19). Although there were some adverse events, palbociclib was generally well tolerated, so dose reduction was needed for only six patients (14%). Conclusion: The efficacy of palbociclib among heavily treated hormone receptor-positive/HER2− patients with advanced breast cancer was acceptable in terms of clinical benefit, and it was generally well tolerated among this population.

Lorlatinib is a third-generation tyrosine-kinases inhibitor (TKI) targeting ALK/ROS1 fusions. The FDA has approved lorlatinib for TKI-pretreated ALK(+) NSCLC, while its approval for ROS1(+) is still pending. Here we present the largest real-world data of NSCLC patients harboring ALK/ROS1 rearrangements treated with lorlatinib. METHODS: 123 patients were enrolled retrospectively (data cut-off 1/1/2019). Lorlatinib was administered through an early access program for patients with no other available therapy. Outcome and response were defined by each investigator upon RECIST 1.1 criteria. RESULTS: 106 ALK(+) and 17 ROS1(+) patients recruited from 8 different countries. The ALK(+) cohort included 50 % males, 73 % never-smokers and 68 % with brain metastases. Extracranial (EC) and intracranial (IC) response rates (RR) were 60 % and 62 %, with disease control rates (DCR) of 91 % and 88 % respectively. Mean duration of therapy (DoT) was 23.9⯱â¯1.6 months and median overall survival (mOS) was 89.1⯱â¯19.6 months. ROS1 cohort enrolled 53 % males, 65 % never-smokers and 65 % had brain metastases. EC and IC RR were 62 % and 67 % with DCR of 92 % and 78 % respectively. Median DoT was 18.1⯱â¯2.5 months and mOS of 90.3⯱â¯24.4 months. OS and DoT in both cohorts were not significantly correlated with line of therapy nor other parameters. The most common adverse events of any grade were peripheral edema (48 %), hyperlipidemia (47 %), weight gain (25 %) and fatigue (30 %). CNS adverse events such as cognitive effect of grade 1-2 were reported in 18 % of patients. CONCLUSION: Lorlatinib shows outstanding EC/IC efficacy in ALK/ROS1(+) NSCLC. The observed mOS of 89⯱â¯19 months in ALK(+) NSCLC supports previous reports, while mOS from of 90⯱â¯24 months is unprecedented for ROS1(+) NSCLC.

PURPOSE: We aimed to investigate the compliance of Turkish Medical Oncologists to antiemetic guidelines for treatment of acute and delayed chemotherapy-induced nausea and vomiting (CINV) in patients receiving high (HEC), moderate (MEC), and low (LEC) emetogenic chemotherapy. METHOD: A covering electronic mail letter with an online questionnaire link was sent to e-mail and mobile application groups including all 599 members of the Turkish Society of Medical Oncology in January 2018. The online survey has consisted of twelve questions. RESULTS: Questionnaire form was responded by 146 of Turkish Medical Oncologists. The most of the participants were following up more than one antiemetic guideline (53%). While compliance with the antiemetic guidelines was higher in acute CINV prophylaxis for HEC and MEC, it was significantly lower in the delayed CINV treatment of HEC and LEC. The highest and lowest compliance rate was found in the prophylaxis of acute and delayed CINV of HEC (92% and 15%, respectively). The incidence of noncompliance for delayed CINV in HEC was statistically significantly higher in those who worked for ≤ five years in an oncology department, under 39 years of age, and non-academicians (p = 0.004, p = 0.042, p = 0.005, respectively). CONCLUSIONS: Noncompliance with the antiemetic guidelines is continue to be a big problem in Turkish Medical Oncologists. The use of standardized antiemetic protocols in chemotherapy order forms or a computerized decision-support system is now seen as a better tool to enhance compliance with the guidelines.

PURPOSE: Colorectal cancer is one of the most common malignancies in the World. RAS-BRAF mutational status and primary tumor location are also important factors for the selection of optimal combinations therapies. In this study, we aimed to evaluate the Turkish oncologists' treatment decisions depending on tumor location and mutational status in metastatic colorectal cancer. METHODS: An online survey link was sent to the medical oncologists who are registered to Turkish Society of Medical Oncology via e-mail and mobile applications. RESULTS: Ninety-four oncologists (85.5%) reported that tumor localization affects their treatment modality. In RAS-BRAF wild type left colon tumors, Turkish oncologists mostly use chemotherapy and anti-EGFR therapy (90.1%) for the first-line treatment, while on the right side, oncologists favored anti-VEGF therapy in combination with chemotherapy (65.5%). BRAF-mutant tumors in left colon had nearly the same rates of treatment tendency with both anti-VEGF and anti-EGFR antibodies in combination with chemotherapy, while in right-sided tumors the main treatment selection of the participants was anti-VEGF-based treatment (83.6%). In RAS-mutant patients, a great number of oncologists selected anti-VEGF-based treatment. On the right and left colon tumors, anti-VEGF treatment options ratios were 91.7 and 92.7%, respectively. Maintenance treatment is usually preferred by oncologists in both anti-VEGF and anti-EGFR-based treatment. CONCLUSION: Turkish oncologists are considering tumor sidedness as an indicator for treatment individualization of patients. The selection of monoclonal antibodies is being affected by tumor localization and mutation status.
