ABSTRACT
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.

Central nervous system (CNS) metastases can be seen at a rate of 30% in advanced stages for patients with non-small cell lung cancer (NSCLC). Growing evidence indicates the predictive roles of driver gene mutations in the development of brain metastases (BM) in recent years, meaning that oncogene-driven NSCLC have a high incidence of BM at diagnosis. Today, 3rd generation targeted drugs with high intracranial efficacy, which can cross the blood-brain barrier, have made a positive contribution to survival for these patients with an increased propensity to BM. It is important to update the clinical and pathological factors reflected in the survival with real-life data. A multi-center, retrospective database of 306 patients diagnosed with driver mutant NSCLC and initially presented with BM between between November 2008 and September 2022 were analyzed. The median progression-free survival (mPFS) was 12.25 months (95% CI, 10-14.5). While 254 of the patients received tyrosine kinase inhibitor (TKI), 51 patients received chemotherapy as first line treatment. The median intracranial PFS (iPFS) was 18.5 months (95% CI, 14.8-22.2). The median overall survival (OS) was 29 months (95% CI, 25.2-33.0). It was found that having 3 or less BM and absence of extracranial metastases were significantly associated with better mOS and iPFS. The relationship between the size of BM and survival was found to be non-significant. Among patients with advanced NSCLC with de novo BM carrying a driver mutation, long-term progression-free and overall survival can be achieved with the advent of targeted agents with high CNS efficacy with more conservative and localized radiotherapy modalities.

The prognosis of patients with advanced HCC can vary widely depending on factors such as the stage of the cancer, the patient's overall health, and treatment regimens. This study aimed to investigate survival outcomes and associated factors in patients with hepatocellular carcinoma (HCC). In this retrospective study, data from 23 medical oncology clinics were analyzed. Progression-free survival (PFS) and overall survival (OS) values were estimated using the Kaplan-Meier method. Prognostic factors associated with survival which were identified in univariate analysis were subsequently evaluated in a multivariate Cox-regression survival analysis was conducted using the backward stepwise (Conditional LR) method to determine the independent predictors of PFS and OS. Of 280 patients, 131 received chemotherapy and 142 received sorafenib, 6 received atezolizumab plus bevacizumab and 1 received nivolumab for first-line setting. The median follow-up time was 30.4 (95%CI 27.1-33.6) months. For-first line, median PFS was 3.1 (95%CI2.7-3.5) months, and it was significantly longer in patients who received sorafenib or atezolizumab-bevacizumab or nivolumab (PFS 5.8 (95%CI 4.2-7.5) than in those received chemotherapy (PFS 2.1 (95%CI 1.9-2.3) in the first-line setting (p < 0.001). Multivariate analysis revealed that male gender (HR: 2.75, 95% CI: 1.53-4.94, p = 0.01), poor ECOG performance score (HR: 1.88, 95% CI: 1.10-3.21, p = 0.02), higher baseline AFP level (HR: 2.38, 95% CI: 1.54-3.67, p < 0.001) and upfront sorafenib treatment (HR,0.38; 95% CI: 0.23-0.62, p < 0.001) were significantly associated with shorter PFS. The median OS was 13.2 (95%CI 11.1-15.2) months. It was significantly longer in patients who received sorafenib or atezolizumab-bevacizumab or nivolumab in the first-line setting followed by TKIs (sorafenib or regorafenib, OS 18.6 (95%CI 13.8-23.5)) compared to those who received chemotherapy (OS 10.3 (95%CI 6.6-14.1)) in the first-line setting. The multivariate analysis revealed that upfront chemotherapy treatment approach, male gender (HR: 1.77, 95% CI: 1.07-2.94, p = 0.02), poor ECOG performance score (HR: 1.96, 95% CI: 1.24-3.09, p = 0.004) and Child-Pugh score, presence of extrahepatic disease (HR: 1.54, 95% CI: 1.09-2.18, p = 0.01), and higher baseline AFP value (HR: 1.50, 95% CI: 1.03-2.19, p = 0.03) were significantly associated with poor prognosis. Additionally, regarding of treatment sequence, upfront sorafenib followed by regorafenib showed a significantly lower risk of mortality (HR: 0.40, 95% CI: 0.25-0.66, p < 0.001). Sorafenib followed by regorafenib treatment was associated with a significantly lower risk of mortality rather than upfront sorafenib followed by BSC group or upfront chemotherapy followed by TKIs. These findings underscore the importance of the optimal treatment sequences to improve survival in patients with advanced HCC.
ABSTRACT
According to current evidence, testing for germline BRCA pathogenic variants in newly diagnosed breast cancer (BC) patients has the potential to reduce the burden of the disease through targeted therapies and secondary prevention. A personalized approach to testing can lead to improved individual outcomes for patients. Despite the proven clinical utility and therapeutic impact of BRCA1/2 tests in shaping therapy for metastatic BC, awareness and access to these tests are limited in many developing countries, including Türkiye. This limitation impacts the healthcare economy as delayed or missed interventions can lead to increased long-term costs. The limited access is mainly due to fear of stigmatization among patients, country-specific legislation and costs, a lack of awareness, vagueness surrounding the tests and access restrictions. This review offers a perspective for policymakers and healthcare providers in Türkiye to establish pathways that integrate the patient experience into comprehensive care pathways and national cancer control plans.
Recent studies show that testing for a specific gene change in people newly diagnosed with breast cancer can help reduce the impact the disease has on their life as they can be given special treatments. When tests are tailored to each person, they can get better results. However, in many countries, including Türkiye, not many people know about or can get these tests. This is because of concerns about being judged, rules in the country, the cost, confusion about the tests and limited access. Not having these tests can make healthcare more expensive in the long run. This article suggests ways for Türkiye's leaders and health workers to make these tests a regular part of cancer care and planning.

INTRODUCTION: This study aims to report the efficacy and safety of capecitabine plus temozolomide (CAPTEM) across different lines of treatment in patients with metastatic neuroendocrine tumors (NETs). METHODS: We conducted a multicenter retrospective study analyzing the data of 308 patients with metastatic NETs treated with CAPTEM between 2010 and 2022 in 34 different hospitals across various regions of Turkey. RESULTS: The median follow-up time was 41.0 months (range: 1.7-212.1), and the median age was 53 years (range: 22-79). Our results across the entire patient cohort showed a median progression-free survival (PFS) of 10.6 months and a median overall survival (OS) of 60.4 months. First-line CAPTEM treatment appeared more effective, with a median PFS of 16.1 months and a median OS of 105.8 months (median PFS 16.1, 7.9, and 9.6 months in first-, second- and ≥third-line respectively, Pâ =â .01; with median OS values of 105.8, 47.2, and 24.1 months, respectively, Pâ =â .003) In terms of ORR, the first-line treatment again performed better, resulting in an ORR of 54.7% compared to 33.3% and 30.0% in the second and third or higher lines, respectively (Pâ <â .001). Grade 3-4 side effects occurred only in 22.5% of the patients, leading to a discontinuation rate of 9.5%. Despite the differences in outcomes based on treatment line, we did not observe a significant difference in terms of side effects between the first and subsequent lines of treatment. CONCLUSIONS AND RELEVANCE: The substantial superior outcomes in patients receiving first-line CAPTEM treatment highlight its potential as an effective treatment strategy for patients with metastatic NET.

Introduction: Breast cancer is the most frequently diagnosed cancer in women worldwide. Aromatase inhibitors (AIs) are effective treatment options for both early-stage and advanced hormone receptor-positive breast cancer. Because of AIs are used long term in adjuvant therapy, side effects are also very important. It is considered that AIs may affect cognitive functions by decreasing the level of estrogen in the brain. The purpose of our study is that evaluate the relationship between duration of treatment and cognitive functions in patients with breast cancer who use AIs in adjuvant therapy. Methods: Two-hundred patients diagnosed with breast cancer who were treated with AIs as adjuvant treatment were included. The patients were surveyed for demographic characteristics. Montreal Cognitive Assessment (MoCA) and Standardized Mini-Mental State Examination (SMMT) tests were performed to evaluate patients' cognitive functions. The total scores of the tests and the orientation, short-time memory, visuospatial functions, attention, language, executive functions which are the MoCA subscales were evaluated separately. Patients were grouped as 0-6, 6-12, 12-24, 24-36, 36, and more months according to the duration of AIs using time. Results: The total MoCA and SMMT scores were affected by factors such as age, education level, and employment status. There was no relationship between duration of treatment and cognitive functions in patients with breast cancer who use AIs in adjuvant therapy (P > 0.05). In addition, no statistically relationship was found in the evaluation of MoCA subscales (P > 0.05). Discussion: Prolonged adjuvant treatment with AIs does not affect cognitive functions in hormone receptor-positive breast cancer patients.

BACKGROUND: Most of the studies on salivary gland cancers are limited for various reasons such as being single-center, small number of patients, including only major or minor SGCs, or only including epidemiological data. METHODS: A total of 37 medical oncology clinics from different regions of Turkey participated in this retrospective-multicenter study. The analyzed data included clinical and demographical features, primary treatment, metastasis localizations, and treatments and includes certain pathologic features. RESULTS: The study included data from a total of 443 SGCs. 56.7% was in major salivary glands and 43.3% was in minor salivary glands. Distant metastasis in the major SGCs was statistically significantly more common than in the minor SGCs, locoregional recurrence was statistically significantly more common in the minor SGCs than in the major SGCs (p = 0.003). CONCLUSIONS: Epidemiological information, metastasis and recurrence patterns, treatment modalities, and survival analysis of the patients over 20 years of follow-up are presented.

AIM: Description of patient characteristics, effectiveness and safety in Turkish patients treated with pazopanib for metastatic soft tissue sarcoma (STS). PATIENTS AND METHODS: This multicenter study is based on retrospective review of hospital medical records of patients (≥ 18 years) treated with pazopanib for non-adipocytic metastatic STS at 37 Oncology clinics across Turkey. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) were evaluated with further analysis of data on the three most common histological subtypes (leiomyosarcoma [LMS], undifferentiated pleomorphic sarcoma [UPS], synovial sarcoma [SS]) in the cohort. RESULTS: Data of 552 adults (57.6% women, median age: 52 years) were analyzed. DCR and ORR were 43.1% and 30.8%, respectively. Median PFS was 6.7 months and OS was 13.8 months. For LMS, UPS and SS, median PFSs were 6.1, 5.9 and 7.53 months and median OSs were 15.03, 12.87 and 12.27 months, respectively. ECOG ≥ 2 was associated with poor PFS and OS. Liver metastasis was only a factor for progression. Second-line use of pazopanib (vs. front-line) was associated with better PFS, its use beyond third line predicted worse OS. Adverse events (AE) occurred in 82.7% of patients. Most common AEs were fatigue (58.3%) and anorexia (52.3%) which were graded as ≥ 3 in 8.2% and 7.4% of patients, respectively. CONCLUSION: Pazopanib is effective and well-tolerated in treatment of non-adipocytic metastatic STS. Its earlier use (at second-line), good performance status may result in better outcomes. Worldwide scientific collaborations are important to gain knowledge on rarer STS subtypes by conducting studies in larger patient populations.

BACKGROUND: There is no standard treatment recommended at category 1 level in international guidelines for subsequent therapy after cyclin-dependent kinase 4/6 inhibitor (CDK4/6) based therapy. We aimed to evaluate which subsequent treatment oncologists prefer in patients with disease progression under CDKi. In addition, we aimed to show the effectiveness of systemic treatments after CDKi and whether there is a survival difference between hormonal treatments (monotherapy vs. mTOR-based). METHODS: A total of 609 patients from 53 centers were included in the study. Progression-free-survivals (PFS) of subsequent treatments (chemotherapy (CT, n:434) or endocrine therapy (ET, n:175)) after CDKi were calculated. Patients were evaluated in three groups as those who received CDKi in first-line (group A, n:202), second-line (group B, n: 153) and ≥ 3rd-line (group C, n: 254). PFS was compared according to the use of ET and CT. In addition, ET was compared as monotherapy versus everolimus-based combination therapy. RESULTS: The median duration of CDKi in the ET arms of Group A, B, and C was 17.0, 11.0, and 8.5 months in respectively; it was 9.0, 7.0, and 5.0 months in the CT arm. Median PFS after CDKi was 9.5 (5.0-14.0) months in the ET arm of group A, and 5.3 (3.9-6.8) months in the CT arm (p = 0.073). It was 6.7 (5.8-7.7) months in the ET arm of group B, and 5.7 (4.6-6.7) months in the CT arm (p = 0.311). It was 5.3 (2.5-8.0) months in the ET arm of group C and 4.0 (3.5-4.6) months in the CT arm (p = 0.434). Patients who received ET after CDKi were compared as those who received everolimus-based combination therapy versus those who received monotherapy ET: the median PFS in group A, B, and C was 11.0 vs. 5.9 (p = 0.047), 6.7 vs. 5.0 (p = 0.164), 6.7 vs. 3.9 (p = 0.763) months. CONCLUSION: Physicians preferred CT rather than ET in patients with early progression under CDKi. It has been shown that subsequent ET after CDKi can be as effective as CT. It was also observed that better PFS could be achieved with the subsequent everolimus-based treatments after first-line CDKi compared to monotherapy ET.

INTRODUCTION: Lung cancer (LC) is the most common cancer in the world.Well known causes are long term smoking, environmental influences and genetic variations. LC is divided into two main types based on their histological phenotypes; small cell lung cancer (SCLC), and non-small cell lung cancer (NSCLC). The high specificity of these new screening methods, which are non-invasive, safe, inexpensive and simple to perform, is important in the early diagnosis and prognosis of cancer. MicroRNAs are significant biomarkers on the diagnosis metastasis and targeted therapies of NSCLC. In our study, we aimed to investigate the potential of using microRNAs as a biomarker in the early diagnosis of lung cancer. MATERIAL AND METHOD: Twenty patients diagnosed with lung cancer and twenty healthy individuals of the same age and gender were selected as the control group. Sixteen microRNAs were studied from blood samples. RESULT: Sixteen miRNAs (Let -7c, Let-7g, miR-1, miR-21, miR-29a, miR-31, miR-34a, miR 103a, miR-141, miR-155, miR-193b, miR-200b, miR-205, miR-340, miR-486, miR-708) were selected for tests and MiR 181 and miR 192 were used as the endogenous control group in line with their binding potentials and gene expression levels. The most specific and sensitive miRNAs were mirR-29a, miR-103a, and miR486 according to endogen controls in patients and healthy subjects. DISCUSSION: A meta-analysis study showed that circulating miRNAs could be promising biomarkers for early diagnosis of lung cancer. Overall, 17 studies were included evaluating 35 miRNA markers and 19 miRNA panels in serum or plasma. The potential role of circulating miRNAs for non-invasive lung screening has been highlighted. In conclusion, there is a need for further validation studies for the use of three miRNAs as a biomarker in the early diagnosis and prognosis of lung cancer.

AIM: To evaluate the difference of progression free survival between the patients using concomitant proton pump inhibitors and non-users in the patients using CDK 4/6 inhibitors with HR + and HER2 negative mBC. METHODS: We included 86 patients with HR + and HER 2 negative mBC treated with CDK 4/6 inhibitors in this study. Patients were divided into two categories according to their status of PPI use. The primary end points was progression free survival (PFS). We compared PPI users and non-users. RESULTS: Forty-five (52.3%) patients used a PPI concomitantly with a CDK 4/6 inhibitor, and 41 (47.7%) did not. The median duration of follow-up was 10.68 (1.94-27.56) months. Of the patients, 50 (58.1%) palbociclib and 36 (41.9%) received ribociclib. The median progression free survival (mPFS) was 10.9 months (95% CI: 7.5-14.27) in the group with concomitant PPI use with a CDK 4/6 inhibitor, whereas the median progression free survival could not be reached in the group without concomitant PPI use (p = 0.04). In addition, concomitant PPI use with palbociclib was associated with a shorter PFS; there was no significant difference between the concomitant PPI users and non-users in terms of PFS in the patients using ribociclib. CONCLUSION: Palbociclib and ribociclib are weak base drugs so their bioavailability is pH-dependent. PPIs can affect their solubility and their concentration in the plasma. Therefore, we must avoid concomitant use of PPIs and CDK 4/6 inhibitors. If we need to use concomitant PPI and CDK 4/6 inhibitors, we should prefer ribociclib than palbociclib.

PURPOSE: Abemaciclib, a CDK4 & 6 inhibitor, is indicated for advanced breast cancer treatment. Diarrhea is a frequently associated adverse event of abemaciclib. The study objective was to investigate if food intake impacts local gastrointestinal toxicity. METHODS: This Phase 2 study (I3Y-MC-JPCP, NCT03703466) randomized 72 patients 1:1:1 to receive abemaciclib 200 mg monotherapy twice daily (1) with a meal, (2) in a modified fasting state or (3) without regard to food. Primary endpoints included: incidence of investigator assessed severe (≥ Grade 3), prolonged (> 7 days) Grade 2 diarrhea, treatment discontinuation, dose modifications, and loperamide utilization during the first 3 cycles of treatment. Patient outcomes were captured via a daily electronic diary. Pharmacokinetics (PK) are reported. RESULTS: Incidence of investigator assessed severe diarrhea (Grade ≥ 3) was 1.4% (1 patient in Arm 1). Median duration of Grade 3 diarrhea was 1 day by both investigator assessment (1 patient in Arm 1) and patient-reported assessment (1 patient each in Arms 1 and 3). Median duration of investigator-assessed Grade 2 diarrhea was 2 days overall. No patient discontinued treatment due to diarrhea. Nine patients (12.7%) had a dose reduction, and 7 patients (9.9%) had a dose omission due to diarrhea. Ninety-four percent of patients used loperamide at least once. Abemaciclib PK was comparable across the 3 arms. CONCLUSION: The results suggest that diarrhea incidence associated with abemaciclib was unrelated to timing of food intake, was predominantly low grade, of short duration and well managed with loperamide and dose modifications.

INTRODUCTION: Prostate cancer (PCa) is a common type of cancer in western countries and prominent cause of mortality in men. The aim of the study was to analyze circulating miRNAs as biomarkers in the sera of healthy individuals and prostate cancer cases without biopsy. MATERIAL AND METHODS: Twenty prostate cases, age (mean and range) 61,4±12.1 (45-73), and twenty healthy men, age 59,3±11.2 (44-70) were included to the study. The mean and range of prostate spesific antigen (PSA) in cancer cases and healthy individuals were 6.79±2.84 ng/ml (2.25-14.7) and 3.8±2.2 ng/ml (1.3-7.8) respectively. RESULTS: Seven miRNAs including two internal controls (Let7c, miR125b, miR141, miR145, miR 155, miR181 ve miR192) were evaluated in two groups. The level of miR141 was significantly lower in PCa cases than healthy individuals (p=0,004), and miR155 was significantly higher (p=0,005) in PCa cases. Both miRNAs were explored sensitive and spesific in the ROC analysis. Tumor mass were found to be associated with the level of miR-125b and miR-145. Conclusion; validation studies are required in wider patient groups in the subject of tumor effect and miRNA biomarkers in prostate cancer.

PURPOSE: Atezolizumab has been shown to be effective and safe in randomized trial in the first-line treatment of extensive-stage small cell lung cancer (SCLC). However, there are limited real-life data on atezolizumab. In this study, we aimed to determine the real-life efficacy and safety of atezolizumab combined with chemotherapy in the first-line treatment of extensive-stage SCLC. METHODS: This trial is a retrospective multicenter study of the Turkish Oncology Group, which included extensive-stage SCLC patients who received atezolizumab combined with chemotherapy in a first-line treatment. The characteristics of the patients, treatment and response rates, and PFS and OS are presented. Factors associated with PFS and OS were analyzed by univariate and multivariate analysis. RESULTS: A total of 213 patients at the 30 oncology centers were included. The median number of chemotherapy cycle was 5 (1-8) and atezolizumab cycle was 7 (1-32). After median 11.9 months of follow-up, median PFS and OS was 6.8 months (95%CI 5.7-7.8), and 11.9 months (95%CI 11-12.7), respectively. The ORR was 61.9%. ECOG-PS (p = 0.002) and number of metastatic sites (p = 0.001) were associated with PFS and pack-year of smoking (p = 0.05), while ECOG-PS (p = 0.03) and number of metastatic sites (p = 0.001) were associated with OS. Hematological side effects were common and toxicities were manageable. CONCLUSION: This real-life data confirm the efficacy and safety of atezolizumab in combination with chemotherapy in first-line treatment of extensive-stage SCLC.

PURPOSE: Febrile neutropenia resulting from chemotherapy is a significant cause of morbidity and mortality in cancer patients. We had previously published the associates of the risk of febrile neutropenia, and this study now extends and modifies the previous model as well as tests its external validity. METHODS: We have recruited documented febrile neutropenia cases with solid tumors, in addition to a selected control group of cancer patients from one institution treated between 2015 and 2019. We then united our sample with our previously published original derivation group, to modify and update our previous model by logistic regression analysis. Additionally, consecutive cancer patients from 5 institutions were recruited in 2020 to test external validity of the resultant algorithm. RESULTS: A total of 4075 cycles of chemotherapy in 1282 cases were recruited in the updated, new model derivation group, and a total of 8 variables were selected for the updated algorithm. In the new external validation group, 653 cycles of chemotherapy in 624 patients were analyzed, to indicate that after cycles without prophylactic granulocyte colony-stimulating factor (GCSF) usage, the algorithm yielded a sensitivity value of 91%, specificity of 40%, and an area under curve (AUC) figure of 0.78, when a risk cutoff threshold value of ≥ 0.20 is chosen. This algorithm is now embedded in a web application for free clinical use. CONCLUSION: Our algorithm identifies and quantifies the risk of febrile neutropenia in cancer patients. Further studies are required to improve this model with additional predictors.

PURPOSE: In this study, we looked for whether treatment-induced rash predicts treatment efficacy in patients with recurrent/metastatic HNSCC treated with Cetuximab and chemotherapy. METHODS: Patients who were treated with platinum-based chemotherapy and cetuximab for the first line treatment of recurrent/metastatic HNSCC were recruited. Presence of rash, hypomagnesemia, hypopotassemia, anemia, neutropenia, thrombocytopenia during treatment and treatment response, date of progression, date of last visit and death were recorded. RESULTS: A total of 138 patients' data were available for analysis. Any grade of rash was detected in 57 (44.5%) of the patients. The incidence of rash was significantly higher in patients with objective response than in patients with disease progression (%56.8 vs %14.3, p < 0.001). Progression free survival was 7.06 months (4.98-9.15) in patients treated with cetuximab and chemotherapy as first line treatment. In the multivariate analysis; rash was significantly correlated with longer PFS (HR 2.136; 95% CI 1.067-4.278; p = 0.032). Progression free survival was 9.65 months in patients who experienced rash, and 6.02 months in patients without rash, (p = 0.019, log-rank test). Overall survival was 11.24 months (9.65-12.82). In multivariate analysis, the survival of patients with rash was significantly longer than patients without rash (HR 1.954; 95% CI 1.162-3.285; p = 0.012). Overall survival was 15.08 months in patients who experienced rash, and 8.61 months in patients without rash (p = 0.05, log-rank test). CONCLUSION: Cetuximab-induced rash is associated with better ORR and longer PFS and OS in patients with recurrent/metastatic HNSCC treated with Cetuximab and platinum-based chemotherapy.

BACKGROUND: The most common age at which gastric cancer is diagnosed is 70 years, and the majority of patients diagnosed are at the metastatic stage. However, although gastric cancer is a geriatric disease, there is no suggestion to discriminate treatment for the general geriatric patient population. Here, we evaluated patients receiving palliative chemotherapy for gastric cancer owing to advanced age. PATIENTS AND METHODS: Multicenter data of geriatric patients receiving palliative chemotherapy because of metastatic gastric cancer were retrospectively reviewed. RESULTS: In total, 262 geriatric patients with gastric cancer were included in the study. Of these, 167 patients, including 134 (51.8%) patients with metastasis at diagnosis and 33 patients with relapse after surgery, were evaluated for palliative therapy. Chemotherapy was started in 87 (52.1%) of 167 patients. The overall median survival of the patients receiving chemotherapy was 9.3 months. There was no difference in overall survival (OS) between patients aged >70 and <70 years. However, a significant difference was detected in OS of patients depending on their Eastern Cooperative Oncology Group (ECOG) performance status (PS) before treatment; survival was 15 months in the group with PS 0-1 and 7 months in the group with PS ≥2. CONCLUSION: Advanced age chemotherapy receiving rates in patients with metastatic gastric cancer is decreasing. Survival is not associated with age, but pretreatment ECOG PS is important. Therefore, ECOG PS and comorbidities should be evaluated in detail, and combination therapies could contribute to patient survival.
