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 objective of this study was to explore the possible association between low skeletal muscle mass (SMM)-assessed by computed tomography (CT) and ultrasound (US)-and hematologic toxicity in cancer patients. A prospective cohort study was conducted in cancer patients who received anthracycline-based chemotherapy between 2018 and 2020 and who had baseline abdominal CT including L3 level for measuring SMM. Regional muscle measurements were carried out using US. A total of 65 patients (14 males, 51 females) were included. ROC (receiver operating characteristic) analysis identified threshold values of 18.0 mm [AUC (area under the curve) = 0.765] for females and 20.0 mm (AUC = 0.813) for males, predicting severe neutropenia. Using these cut-offs, females with low rectus femoris (RF) thickness (<18.0 mm) had a significantly higher incidence of grade ≥3 neutropenia (50.0% vs. 10.8%, p = 0.005), and males with low RF values (<20.0 mm) had a higher incidence (80.0% vs. 22.2%, p = 0.063). A regression analysis, irrespective of age, gender, and body mass index, revealed that only low RF muscle thickness increased the risk of grade 3-4 neutropenia by 9.210 times (95% CI = 2.401-35.326, p = 0.001). Utilizing US to measure RF muscle thickness aids in identifying cancer patients at an elevated risk of developing neutropenia. Needless to say, US can serve as a convenient and easily accessible tool for assessing low SMM, providing repeat point-of-care evaluations in clinical practice.
RESUMEN
Anemia remains an essential concern affecting the quality of life and the survival of cancer patients. Although there are different approaches to treating anemia in cancer patients, the number of studies reporting the efficacy of iron replacement in cancer patients is limited. In this study, the efficacy and safety of iron carboxymaltose, a parenteral iron treatment option, in the treatment of anemia, were examined retrospectively. A total of 1102 adult patients who received IV ferric carboxymaltose treatment at Hacettepe Oncology Hospital between 2014 and 2020 were included. The mean hemoglobin change observed at the end of the 12th week was 1.8 g/dL, and the rate of patients with an increase in hemoglobin of 1 g/dL or more was 72.1%. It was observed that the treatment demonstrated effectiveness in patients receiving active cancer treatment in all tumor types. The treatment was generally safe, and no grade 3-5 side effects were observed in the patients included in the study. According to one of the most extensive series published in the literature, iron carboxymaltose is an efficient and safe alternative for cancer patients with iron-deficiency anemia.

PURPOSE: Anaplastic lymphoma kinase (ALK) mutations occurs in approximately 3-5% of patients with non-small cell lung cancer (NSCLC). Pleural involvement/effusion is common in ALK-positive patients with NSCLC at baseline. The aim of the study was to evaluate the characteristics of ALK-positive patients who have Ple-I/E. METHODS: In this multicenter study, patients with ALK-positive NSCLC who have Ple-I/E were retrospectively analyzed. Clinical and demographic characteristics of the disease, response rates, median progression-free survival (PFS), and overall survival (OS) were evaluated in 362 ALK-positive patients with NSCLC. RESULTS: Of the patients, 198 (54.7%) were male. The median age at the time of diagnosis was 54 (range 21-85) years. All patients' histology was adenocarcinoma (100%). At baseline, 57 (15.7%) patients had Ple-I/E. There was no association between Ple-I/E and gender, lung metastasis, or distant lymphadenopathy (LAP) metastasis. The frequencies of liver, brain, and bone metastases were significantly higher in ALK-positive patients without Ple-I/E compared to those with Ple-I/E (respectively 18.2% vs 4.8%, p = 0.008; 19.1% vs 4.8%, p = 0.001; 20.6% vs 8.9%, p = 0.002). The median PFS was longer in ALK-positive patients who had Ple-I/E (18.7 vs 10.6 months, p = 0.017). Similarly, the median OS was longer in ALK-positive patients who had Ple-I/E (44.6 vs 22.6 months, p = 0.051). CONCLUSION: Brain, liver, and bone metastases were lower in ALK-positive patients with Ple-I/E. Patients presented with Ple-I/E were prone to have better PFS and OS.
RESUMEN
INTRODUCTION: There have been significant advances in the treatment of hepatobiliary cancers, especially for advanced-stage disease. However, data is limited for optimal therapy selection in the first line and sequencing of available options. AREAS COVERED: This review covers the systemic treatment of hepatobiliary cancers with an emphasis on the advanced stage. The previously published and ongoing trials will be discussed to create an algorithm for the current practice and to give future perspectives on how the field could go forward. EXPERT OPINION: While there is no standard-of-care option in the adjuvant treatment of hepatocellular cancer, capecitabine is the standard of care for biliary tract cancer. The efficacy of adjuvant gemcitabine and cisplatin and the added benefit of radiotherapy to chemotherapy are yet to be defined. For the advanced stage, immunotherapy-based combinations became the standard of care for both hepatocellular and biliary tract cancers. The molecularly targeted therapy has profoundly changed the second-line and later treatment for biliary tract cancers, while the optimal second-line treatment for advanced hepatocellular cancer is yet to be defined due to rapid advances in the first-line setting.

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

Introduction: Breast cancer is the most common cancer in women and is the second most common cause of cancer related mortality. Metabolomics, the identification of small metabolites, is a technique for determining the amount of these metabolites. Objectives: This study aimed to identify markers for the early diagnosis of brain metastasis by metabolomic methods in breast cancer patients. Methods: A total of 88 breast cancer patients with distant metastases were included in the study. The patients were divided into two groups according to their metastasis status: patients with brain metastases and distant metastases without any brain metastases. Liquid chromatography quadrupole time-of-flight mass spectrometry (LC-qTOF-MS) and gas chromatography-mass spectrometry (GC-MS) analysis methods were used for metabolomic analyses. Results: 33 of them, 88 patients had brain metastasis, and 55 patients had distant metastases without brain metastasis. A total of 72 and 35 metabolites were identified by the GC-MS and LC-qTOF-MS analysis, respectively. 47 of them were found to be significantly different in patients with brain metastasis. The pathway analysis, performed with significantly altered metabolites, showed that aminoacyl tRNA biosynthesis, valine, leucine and isoleucine biosynthesis, alanine, aspartate, and glutamate metabolism, arginine biosynthesis, glycine, serine, and threonine metabolism pathways significantly altered in patients with brain metastasis. Predictive accuracies for have identifying the brain metastasis were performed with receiver operating characteristic (ROC) analysis, and the model with fifteen metabolites has 96.9% accuracy. Conclusions: While these results should be supported by prospective studies, these data are promising for early detection of brain metastasis with markers in liquid biopsy samples.

OBJECTIVES: In metastatic and recurrent head and neck cancer (M/R HN-SCC), the median survival is less than a year and locoregional recurrence is the main cause of death. Our aim was to evaluate the results of concurrent stereotactic body radiotherapy (SBRT) and immunotherapy (ICI) in these patients. MATERIALS AND METHODS: Fifteen patients diagnosed with M/R HN-SCC were evaluated retrospectively. All patients received SBRT (3x8 Gy) to all recurrent and metastatic foci with concurrent ICI. RESULTS: Six months overall survival (OS) rates and progression-free survival (PFS) rates were 93% and 86%, respectively. Local control (LC) rate in the site of SBRT was 96%. Higher survival and LC rates were achieved with lower doses of radiotherapy with the synergistic effect of SBRT and ICI. CONCLUSION: Concurrent ICI and SBRT was feasible with excellent LC.

Pazopanib is an oral multi-kinase inhibitor approved for the treatment of advanced renal cell carcinoma (RCC). It is an anti-angiogenic agent, which blocks the activation signaling pathways of tyrosine kinases and prevents the activities of primarily vascular endothelial growth factor receptors (VEGFR)-2 and VEGFR-3, which are important in lymphangiogenesis. Herein, we report a patient with advanced RCC who developed asymptomatic left-sided chylothorax under pazopanib therapy. Chylothorax developed in the 16th month and gradually increased until it was diagnosed by thoracentesis in the 22nd month. The development of chylothorax was attributed to pazopanib therapy after ruling out all possible traumatic and nontraumatic etiologies. The 'Adverse Drug Reaction Probability Scale' revealed a total score of 6, which fell into 'probable' category. Chylothorax regressed significantly 5 weeks after the discontinuation of pazopanib therapy.

Background: In node-negative HER2-overexpressed breast cancers, adjuvant paclitaxel plus trastuzumab treatment is a successful de-escalation approach with excellent survival outcomes. Methods: All patients with HER2+ breast cancer treated in our centers were retrospectively reviewed. Results: We analyzed 173 patients who were treated with adjuvant paclitaxel plus trastuzumab. The mean tumor size was 2.2 cm. There were eight invasive disease events or death: four distant recurrences (2.3%), three locoregional recurrences (1.7%) and one death without documented recurrence after a 52 month follow-up. The 3-year disease-free survival and recurrence-free interval rate was 96.6%. Conclusion: This real-life experience with adjuvant paclitaxel plus trastuzumab demonstrated few distant recurrences and is compatible with the APT trial findings.
Lay abstract In oncology practice, there have been some efforts to avoid the toxicity of combination chemotherapies and reduce the amount of treatment given in recent decades. These strategies have been studied especially for patients with a specific subtype of early-stage breast cancer. We present the results from patients treated in our centers and discuss them in relation to the literature.

Objective Liposarcomas are relatively rare tumors. Prognostic and predictive factors and treatment options are limited. We herein presented our 10-year experience with liposarcomas. Materials and Methods Adult patients with liposarcoma treated between 2005 and 2015 in our center were included. Demographic and clinicopathologic features of patients were retrieved from patient files. Statistical Analyses Outcomes in terms of disease-free survival (DFS) and overall survival (OS) were assessed along with potential prognostic factors using Kaplan-Meier analyses. Results A total of 88 patients were included. The median age was 52. Rates of well-differentiated (WDLS), dedifferentiated (DDLS), myxoid (MLS), and pleomorphic liposarcomas (PLS) were 42, 9.1, 37.5, and 4.5%, respectively. Only 10% of patients had high-grade tumors and 93% had localized disease. Ninety-six percent of patients ( n = 84) underwent surgery. Adjuvant chemotherapy was delivered to 16 patients. The most common regimen was ifosfamide-doxorubicin. Recurrences were observed in 30 patients, 21 had local, and 9 had distant metastasis. Five-year DFS of patients with the localized disease was 68%. All patients with PLS had relapses and those had the highest distant relapse rates among all subtypes. Multivariate analysis showed T stage and grade were associated with DFS. Five-year OS of the entire population was 68%. Five-year OS was 79, 76, 50, and 0% in WDLS, MLS, DDLS, and PLS, respectively ( p = 0.002). Conclusion Management of liposarcomas is still challenging. Surgery is the mainstay of treatment. Novel effective therapies are needed, particularly in advanced disease settings.
RESUMEN
PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Background Radiotherapy (RT) with immune checkpoint inhibitors (ICI) has yielded good responses in many cancers. We aimed to report the results of combined fractionated stereotactic radiotherapy (FSRT) and ICI in patients with recurrent high-grade glioma. Methodology Patients were treated with FSRT and nivolumab which were continued until progression or toxicity. The Response Assessment in Neuro-oncology and Immunotherapy Response Assessment in Neuro-oncology criteria were used to assess treatment response on magnetic resonance imaging. Treatment-related toxicity was noted in all patients. Results A total of eight patients were included. Recurrence was detected after a median of 5.8 months following the first RT, all in the treatment field. FSRT (3 × 8 Gy) was applied with neoadjuvant, concurrent, and adjuvant nivolumab. After a median follow-up of 21.3 months from diagnosis and 12.6 months from recurrence, one patient was alive and seven succumbed to the disease. The median overall survival was 20.9 months after diagnosis and 12.9 months after recurrence. The median progression-free interval was 2.3 months after FSRT. The local control (LC) rate was 62.5% with a median local recurrence-free survival of nine months. Progression in other regions of the brain was observed in four patients with a median progression-free survival of 2.1 months. Acute toxicity was not observed. ICI-related grade 3 late pneumonitis was observed in two patients, and grade 1 late thyroid toxicity in two patients. One patient with pneumonitis also developed osteoporosis and radiation necrosis. Conclusions A high LC rate was achieved with concurrent FSRT and ICI with a severe late toxicity rate of 25%. This combination can be an option in recurrent high-grade gliomas.
RESUMEN
BACKGROUND: 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. MATERIALS AND METHODS: 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. RESULTS: 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 (< 65 years). The 24-mo overall survival rate was 76.1% and 49.5% in the afatinib arm and erlotinib/gefitinib arm, respectively. Although all-grade adverse event (AE) rates were similar between the two arms, grade 3-4 AE rates were higher in the afatinib arm (30.7% vs. 15.2%; p: 0.004). DISCUSSION: In our real-world study, afatinib has superior survival outcomes despite worse toxicity profile as inconsistent with clinical study results and it is the good upfront treatment option for younger patients and elderly patients who have good performance status.

BACKGROUND: COVID-19 pandemic could create a collateral damage to cancer care denoting disruptions in care due to a significant burden on healthcare and resource allocations. Herein, we evaluate the early changes in the inpatient and outpatient oncology clinics to take a snapshot of this collateral damage at Hacettepe University Cancer Institute. METHODS: Patients applying the outpatient clinic and outpatient palliative care (OPC) clinic for the first time and patients admitted to inpatient wards in the first 30 days after the first case of COVID-19 in Turkey were evaluated. These data were compared with data from the same time frame in the previous 3 years. RESULTS: The mean number of daily new patient applications to the outpatient clinic (9.87±3.87 vs 6.43±4.03, p<0.001) and OPC clinic (3.87±1.49 vs 1.13±1.46, p<0.001) was significantly reduced compared with the previous years. While the number of inpatient admissions was similar for a month frame, the median duration of hospitalisation was significantly reduced. The frequency of hospitalisations for chemotherapy was higher than in previous years (p<0.001). By comparison, the rate of hospitalisations for palliative care (p=0.028) or elective interventional procedures (p=0.001) was significantly reduced. CONCLUSION: In our experience, almost all domains of care were affected during the pandemic other than patients' systemic treatments. There were significant drops in the numbers of newly diagnosed patients, patients having interventional procedures and palliative care services, and these problems should be the focus points for the risk mitigation efforts for prevention of care disruptions.
RESUMEN
BACKGROUND: Previous studies demonstrated an increased cancer risk in autoimmune diseases. Behçet's disease (BD) was also reported to be associated with an increased risk of cancer, although the data is limited. AIMS: In this study, we aimed to assess cancer incidence in a large cohort of BD patients and to compare with the data of the same age and gender groups. METHODS: The study cohort consisted of BD patients of > 18 years of age who were prospectively recorded in the Hacettepe University Vasculitis Center. Data on any cancer was collected from the patient files. Cancer incidence was compared with age- and gender-specific cancer incidence rates of the normal population retrieved from the 2014 Turkish National Cancer Registry (TNCR) data using standardized incidence rates (SIR). RESULTS: Totally, 451 adult cases with BD were included. The median age of the cohort was 43 (20-75), and 52.5% of the patients were males. Eleven cancer cases were observed during a median of 124 months follow-up. Behçet's disease was associated with an increase in cancer risk compared with expected counts in the corresponding age and sex group (SIR 2.84, 95% CI 1.50-4.94, p < 0.001). Patients with papulopustular lesions had a trend toward a decreased risk of cancer (p = 0.060), and patients using azathioprine had a significantly decreased cancer risk (p = 0.031). CONCLUSION: This study revealed BD patients had approximately three times increased cancer risk compared with corresponding age and sex groups. Besides the routine care, increased attention for cancer surveillance is required in the follow-up of BD patients.

The immune checkpoint inhibitors have opened new horizons in oncology. Although the indications for the use of Immune checkpoint inhibitors in cancer patients are expanding, there is still a need for markers that can aid in patient selection. Gastrointestinal microbiota can be among these markers. Recently, gastrointestinal microbiota stated to have a bidirectional relation with cancer immunotherapy with roles in both prognostic and therapeutic sides. Preclinical data suggest that modulation of the microbiota could become a novel strategy for improving the efficacy of immunotherapy. However, its labile structure prone to be affected by many factors. Further research can delineate the mechanisms of the relationship between microbiota and immunotherapy can have clinical implications.

Introduction: Impaired DNA damage response (DDR) and subsequent genomic instability are associated with the carcinogenic process itself, but it also results in sensitivity of tumor cells to certain drugs and can be exploited to treat cancer by inducing deadly mutations or mitotic catastrophe. Exploiting DDR defects in breast cancer cells has been one of the main strategies in both conventional chemotherapy, targeted therapies, or immunotherapies. Areas covered: In this review, the authors first discuss DDR mechanisms in healthy cells and DDR defects in breast cancer, then focus on current therapies and developments in the treatment of DDR-deficient breast cancer. Expert opinion: Among conventional chemotherapeutics, platinum-based regimens, in particular, seem to be effective in DDR-deficient patients. PARP inhibitors represent one of the successful models of translational research in this area and clinical data showed high efficacy and reasonable toxicity with these agents in patients with breast cancer and BRCA mutation. Recent studies have underlined that some subtypes of breast cancer are highly immunogenic. Promising activity has been shown with immunotherapeutic agents, particularly in DDR-deficient breast cancers. Chemotherapeutics, DNA-repair pathway inhibitors, and immunotherapies might result in further improved outcomes in certain subsets of patients with breast cancer and DDR.

Background/aim: In this study, we aimed to assess the cancer risk among patients with periodontal disease. Materials and methods: Patients diagnosed with periodontal diseases at Hacettepe University between 2007 and 2012 were included and data on the diagnosis of any cancer after periodontal disease were collected from patient files. The age- and sex-standardized incidence rates (SIRs) were calculated using Turkish National Cancer Registry 2013 data. Results: A total of 5199 patients were included. Median follow-up was 7.2 years. Patients with periodontal diseases had 17% increased risk of cancer compared with the expected counts for the corresponding age and sex groups (SIR: 1.17; 95% CI: 1.041.3, P = 0.006). The increased cancer risk was statistically significant in women (SIR: 1.24; 95% CI: 1.051.45, P = 0.008) but not in men. Among women with periodontal disease, the risks of breast cancer (SIR: 2.19) and head and neck cancer (SIR: 4.71) were significantly increased. Among men, the risks of prostate cancer (SIR: 1.84), head and neck cancer (SIR: 3.55), and hematological cancers (SIR: 1.76) were significantly increased. Conclusion: This study showed that periodontal diseases were associated with increased risk of several cancers. Besides other well-known benefits for health, the provision of oral/dental health should be considered and employed as a cancer prevention measure.
