RESUMO
INTRODUCTION: Neoadjuvant chemotherapy (NAC) is extensively employed in breast cancer (BC), primarily for aggressive subtypes like triple-negative and human epidermal growth factor receptor 2 (HER2) positive BC, and in estrogen receptor-positive (ER+)/ HER2- BC with high-risk features. In ER+/HER2- breast cancer, pathological complet rates are much lower (<10%), while axillary dissection rates are higher. This study focuses on hormone receptor positive (HR+)/HER2- BC patients undergoing NAC, examining its impact on pathological complete response (pCR) rates, with specific attention to tumor Ki67 and ER status. METHODS: Retrospective data analysis from Kartal Dr. Lütfi Kirdar City Hospital included HR+/HER2- BC patients who received NAC. Clinicopathological factors, NAC response, and surgical outcomes were assessed. Statistical analyses evaluated the association between Ki67, ER status, and pCR. RESULTS: Of 203 patients, 11.8% achieved pCR. Ki67 (p<0.001) and ER percentage (p<0.001) significantly correlated with pCR. Higher Ki67 was associated with increased pCR likelihood (HR: 1.03, 95% CI: 1.01-1.05). A Ki67-pCR probability curve revealed a cutoff of 23.5%. ER%-pCR analysis showed decreasing pCR rates with higher ER percentages. Multivariate analysis confirmed Ki67 (p=0.003, HR: 1.02) and ER percentage (p=0.019, HR: 0.97) as independent predictors of pCR probability. CONCLUSION: Consideration of Ki67 and ER percentage aids in NAC decisions for HR+/HER2- BC, identifying patients with high NAC response rates, facilitating axillary preservation, and potentially avoiding axillary dissection. The pCR rates in patients with Ki67 ≤ 24 are particularly low, especially in patients with a high ER percentage. In these cases, upfront surgery and adjuvant treatment should be considered instead of NAC.
RESUMO
Background: The treatment and escape for metastatic renal cell carcinoma (RCC) has rapidly evolved, particularly with the integration of immune therapies into first-line regimens. However, optimal strategies following progression in first-line immunotherapy remain uncertain. This study aims to evaluate the efficacy and safety of axitinib and cabozantinib as third-line therapies after progression on nivolumab following first-line VEGF-TKI therapy. Methods: Patients with metastatic RCC who progressed on prior nivolumab treatment after receiving first-line VEGF-TKI therapy were included. Data on patient characteristics, treatment regimens, response rates, progression-free survival (PFS), and overall survival (OS) were collected. Statistical analyses were conducted to assess the prognostic factors and treatment outcomes. Results: A total of 46 patients were included who were predominantly male (83%) with clear-cell histology (89%). The median PFS on first-line TKI therapy was 10.2 months. All the patients received nivolumab as a second-line therapy, with a median of 12 cycles. The median second-line PFS was seven months. Third-line therapies included axitinib (24 patients) and cabozantinib (20 patients). The median PFS for axitinib and cabozantinib was six months, with comparable survival outcomes. The IMDC risk group and treatment tolerability were significant predictors of survival in multivariate analysis. Adverse events were manageable, with hypertension, fatigue, and diarrhea being the most common. Conclusion: Axitinib and cabozantinib show promise as third-line therapies post-nivolumab progression in metastatic RCC, though prospective validation is warranted. This study underscores the need for further research to establish treatment standards in this evolving landscape.

Background and Objectives: Patients with human epidermal growth factor receptor 2 (HER2) -positive, hormone receptor-positive (HR-positive) metastatic breast cancer (MBC) usually undergo trastuzumab emtansine (T-DM1) therapy in subsequent lines. Combining endocrine therapy (ET) with T-DM1 can improve treatment outcomes in this subtype. Therefore, this study aimed to investigate the benefits of using T-DM1 with ET in HER2-positive and HR-positive MBC. This study was the first to investigate the benefits of combining ET with T-DM1. Material and Methods: This study analyzed the medical records of patients with HER2-positive and HR-positive MBC who were treated with T-DM1 from June 2010 to December 2021. The patients were divided into groups based on whether they received concomitant ET with T-DM1. The primary endpoint was to determine the progression-free survival (PFS), while the secondary endpoints were overall survival (OS), objective response rate, and safety of the treatment. Results: Our analysis examined 88 patients, of whom 32 (36.4%) were treated with T-DM1 in combination with ET. The combination therapy showed a significant improvement in median PFS (15.4 vs. 6.4 months; p = 0.00004) and median OS (35.0 vs. 23.1 months; p = 0.026) compared to T-DM1 alone. The ORR was also higher in the combination group (65.6% vs. 29.3%; p = 0.026). Patients treated with pertuzumab priorly had reduced median PFS on T-DM1 compared to those who were not treated with pertuzumab (11.7 vs. 5.4 months, respectively; p < 0.01). T-DM1 demonstrated better median PFS in HER2 3+ patients compared to HER2 2+ patients, with an amplification ratio of >2.0 (10.8 vs 5.8 months, respectively; p = 0.049). The safety profiles were consistent with previous T-DM1 studies. Conclusions: The combination of T-DM1 with ET can significantly improve PFS and OS in patients with HER2-positive and HR-positive MBC. Our study suggests that prior pertuzumab treatment plus trastuzumab treatment might decrease T-DM1 efficacy.

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.

Background: Ribociclib, palbociclib and abemaciclib are currently approved CDK4/6 inhibitors along with aromatase inhibitors as the first-line standard-of-care for patients with hormone receptor-positive, HER2-negative metastatic breast cancer. Methods: The authors report retrospective real-life data for 600 patients with estrogen receptor- and/or progesterone receptor-positive and HER2-negative metastatic breast cancer who were treated with ribociclib and palbociclib in combination with letrozole. Results & conclusion: The results demonstrated that the combination of palbociclib or ribociclib with letrozole has similar progression-free survival and overall survival benefit in real life for the patient group with similar clinical features. Specifically, endocrine sensitivity may be a factor to be considered in the treatment preference.

We aimed to assess the prognostic and predictive significance of pretreatment Prognostic Nutritional Index (PNI) in extensive-stage small-cell lung cancer (ES-SCLC) patients treated with first-line chemotherapy. We designed this study to evaluate the prognostic role of PNI in 147 ES-SCLC patients treated with platinum-based combination regimen between 2011 and 2018. Kaplan-Meier survival analyses and Cox proportional hazard models were used to examine the effects of basal PNI on overall survival (OS). The median age of the patients was 61 (range 38-81). The cutoff value for PNI was determined for whole group and patients were dichotomized into high (≥49.17) and low (<49.17). Seventy-eight (53.1%) patients had low PNI score and 69 (46.9%) patients had high PNI score. Patients with the high PNI score had better OS than those with low PNI (13 versus 12 months, respectively, and P = 0.03). The relationship between PNI score and OS was more prominent in patients over 65 years of age (13 versus 10 months, respectively, and P = 0.03). Progression-free survival of patients with complete response to first-line treatment was statistically significantly better than the other patients (8 versus 7 months, respectively, and P = 0.02). Similarly, OS was statistically significantly better than the other patients (15 versus 8 months, respectively, and P = 0.001). The results of our study show that PNI score is useful in evaluating the OS of patients with ES-SCLC. PNI is a cost-effective prognostic marker and should therefore be included in routine clinical practice.

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.

Concomitant administration of chemotherapy and radiotherapy is currently recognized as the standard of treatment in locally advanced inoperable non-small cell lung cancer (NSCLC). Our study aimed to compare the efficacy and toxicities of three different chemotherapy regimens delivered concurrently with radiotherapy. We retrospectively reviewed the clinical records of patients who received the PE (cisplatin, 50 mg/m(2), on days 1, 8, 29, and 36 plus etoposide, 50 mg/m(2), on days 1 to 5 and 29 to 33), PD (docetaxel, 20 mg/m(2), on day 1 plus cisplatin, 20 mg/m(2), on day 1, every week), and PC (carboplatin, AUC 2 plus paclitaxel, 45 mg/m(2), on day 1, every week) regimens concurrently with radiotherapy. A total of 227 patients were evaluated in the study. Median follow-up time was 13 months (2-101). There were 27 females (11.9 %) and 200 males (88.1 %) with a median age of 61 (38-82) years. The PD group had higher rates of esophagitis, mucositis, and anemia (p < 0.05). The PC group had higher rates of neuropathy (p = 0.000). The progression-free survival (PFS) time was 10 months for patients in the PC group, 15 months for patients in the PD group, and 21 months for the PE group (p = 0.010). Patients in the PC group had a median overall survival time of 23 months, those in the PD group 27 months, and those in the PE group 36 months (p = 0.098). Combination of cisplatin-etoposide with radiotherapy led to a more favorable outcome compared with the other two regimens. It shows generally manageable toxicity profile and compliance to treatment is noticeable.

OBJECTIVE: Immunotherapies are commonly employed for the treatment of non-small-cell lung cancer (NSCLC). However, predictive biomarkers still need to be improved to predict responses to these agents. The lymphocyte-albumin (LA) laboratory index has not been evaluated before in this patient group. The aim of this study was to analyze the relation between the LA index and the survival rate of metastatic NSCLC patients who had immunotherapy after at least one round of chemotherapy. METHODS: The research included 227 patients diagnosed with metastatic NSCLC, who were administered nivolumab after at least one round of chemotherapy. The LA index was calculated by multiplying lymphocyte count and albumin concentration. The optimal threshold values for the index were established by the examination of the ROC curve for both overall survival (OS) and progression-free survival (PFS). Oncological data were obtained retrospectively from patient files, and survival analyses were performed. RESULTS: The median follow-up was 7.9 months. Progression was observed in 129 (56.9%) patients. A total of 97 (42.7%) patients died during the follow-up. The cutoff values of the LA index to predict OS and PFS were determined as 52.87 and 57.67, respectively. The low-LA group had significantly lowered OS and PFS compared to the high-LA group. LA was found to be an independent prognostic factor for PFS (hazard ratio 4.47; 95% confidence interval, 2.73-7.34; p < 0.001) and OS (hazard ratio 6.24; 95% confidence interval, 3.46-11.25; p < 0.001) in the multivariate regression analysis. CONCLUSIONS: In this study, we observed that the LA index independently predicts OS and PFS in immunotherapy-treated metastatic NSCLC patients. Its ease of application, low cost, and noninvasive nature make it a potential guide for clinicians in predicting treatment responses and survival.
RESUMO
BACKGROUND AND OBJECTIVE: Breast cancer (BC) remains a significant health concern, particularly in advanced stages where the prognosis is poor. The combination of endocrine therapy (ET) with cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) has improved outcomes for advanced BC (aBC) patients. However, resistance to CDK4/6i remains a challenge, with no validated biomarkers to predict response. The receptor activator of the nuclear factor-kB (RANK) pathway has emerged as a key player in aBC, particularly in luminal BC. RANK overexpression has been associated with aggressive phenotypes and resistance to therapy. In view of these findings, we proceeded to investigate the potential involvement of the RANK pathway in luminal BC resistance to CDK4/6i. The objective was to evaluate the effectiveness of denosumab in increasing overall survival (OS) and progression-free survival (PFS). METHODS: In this retrospective analysis, 158 BC patients with bone metastases were included. Patients with human epidermal growth factor receptor-2 (HER2)-negative and hormone receptor-positive BC who received palbociclib or ribociclib in addition to antiresorptive medication were included. Patients received either denosumab or zoledronic acid (ZA) therapy. The primary endpoint was OS, with PFS as a secondary endpoint. RESULTS: Although the PFS and OS of denosumab were better than ZA in this study, it did not show a significant difference between the two drugs. Meanwhile, mOS was not achievable in patients in the denosumab group, while it was 34.1 months in patients in the ZA group. The hazard ratio (HR) showed a significant improvement for the denosumab group in patients under 60 of age (HR: 0.33, p<0.01), patients with a score of 1 HER2 overexpression (HR: 0.09, p=0.01), and patients with resistant endocrine (HR: 0.42, p=0.02) compared to ZA. CONCLUSION: This study highlights the potential clinical relevance of the RANK pathway in BC treatment, and our findings suggest that denosumab may offer significant benefits in terms of PFS and OS for certain subgroups, particularly those with HER2 scores of 1, patients under 60, and those with endocrine-resistant BC. In conclusion, considering that RANK pathway status may be a predictive biomarker for CDK4/6i treatment and may cause treatment resistance, our results demonstrate the clinical relevance of the combination of CDK4/6i + ET with RANKL inhibition.
RESUMO
Introduction: Pulmonary large cell neuroendocrine carcinoma (PLCNEC) is a rare but aggressive subtype of lung cancer with an incidence of approximately 3 %. Identifying effective prognostic indicators is crucial for guiding treatments. This study examined the relationship between inflammatory markers and PLCNEC patient overall survival (OS) and sought to determine their prognostic significance in PLCNEC. Methods: Patients diagnosed with PLCNEC between 2007 and 2022 at the oncology center, were retrospectively included. Patients who underwent surgery were pathologically re-staged post-surgery. Potential prognostic parameters (neutrophil/lymphocyte ratio, platelet/lymphocyte ratio [PLR], panimmune inflammatory value, prognostic nutritional index and modified Glasgow prognostic score [mGPS]) were calculated at that time of diagnosis. Results: Sixty patients were included. The median follow-up was 23 months. Thirty-eight patients initially diagnosed with early or locally advanced. The mGPS was identified as a poor prognostic factor that influenced disease free survival (DFS) fourfold (p = 0.03). All patients' median OS was 45 months. Evaluating factors affecting OS in all patients, statistically significant relationships were observed between OS and the prognostic nutritional index (p = 0.001), neutrophil/lymphocyte ratio (p = 0.03), platelet/lymphocyte ratio (p = 0.002), and pan-immunoinflammatory value (p = 0.005). Upon multivariate analysis, the platelet/lymphocyte ratio was identified as an independent poor prognostic factor for OS, increasing the mortality risk by 5.4 times (p = 0.002). Conclusion: mGPS was significantly linked with prognosis in non-metastatic PLCNEC, with patients with higher mGPS exhibiting poorer long-term DFS. This finding contributes to the evolving understanding of PLCNEC. The multivariable predictive model we employed suggests that PLR is an independent predictor of OS at all stages. A lower PLR was correlated with worse overall survival. Thus, PLR can be a readily accessible and cost-effective prognostic factor in PLCNEC patients.
RESUMO
Neoadjuvant chemotherapy (NACT) is the standard treatment for locally advanced, high-risk breast cancer. Pathological complete response (pCR) improves survival. Peripheral blood-derived indices reflecting systemic inflammation and nutritional status have long been used as predictive and prognostic markers in solid malignancies. This retrospective study investigates whether eight commonly used indices in patients receiving NACT affect pCR and survival. This study includes 624 locally advanced breast cancer patients who received NACT. The biomarker indices were calculated from peripheral blood samples taken two weeks before starting chemotherapy. The indices' optimal cut-off values were determined using ROC Curve analysis. During a median follow-up period of 42 months, recurrence was detected in 146 patients, and 75 patients died. pCR was observed in 166 patients (26.6%). In univariate analysis, NLR, PLR, SII, PNI, HALP, and HRR were statistically significantly associated (p = 0.00; p = 0.03; p = 0.03; p = 0.02; p = 0.00; p = 0.02 respectively), but in multivariate analysis, only NLR was significantly predictive for pCR(p = 0.04). In multivariate analysis, the HGB/RDW score significantly predicted DFS(p = 0.04). The PNI score was identified as a marker predicting survival for both OS and PFS (p = 0.01, p = 0.01, respectively). In conclusion, peripheral blood-derived indices have prognostic and predictive values on pCR and survival. However, further studies are needed to validate our findings.

BACKGROUND: Neoadjuvant treatment is the standard treatment in locally advanced ESCC. However, the optimal chemotherapy regimen is not known. METHOD: This is a retrospective observational cohort study conducted with propensity score matching. Patients with resectable ESCC from 13 tertiary centers from Türkiye were screened between January 2011 and December 2021. We compared the efficacy and safety of neoadjuvant chemoradiotherapy with the CF and the CROSS regimens in patients with ESCC. RESULTS: Three hundred and sixty-two patients were screened. Patients who received induction chemotherapy (n = 72) and CROSS-ineligible (n = 31) were excluded. Two hundred and fifty nine patients received neoadjuvant chemoradiotherapy. After propensity score matching (n = 97 in both groups), the mPFS was 18.4 months (95% CI, 9.3-27.4) and 25.7 months (95% CI, 15.6-35.7; p = 0.974), and the mOS was 35.2 months (95% CI, 18.9-51.5) and 39.6 months (95% CI 20.1-59.2; p = 0.534), in the CF and the CROSS groups, respectively. There was no difference between subgroups regarding PFS and OS. Compared with the CF group, the CROSS group had a higher incidence of neutropenia (34.0% vs. 62.9%, p < 0.001) and anemia (54.6% vs. 75.3%, p = 0.003) in all grades. On the other hand, there was no significant difference in grade 3-4 anemia, grade 3-4 neutropenia, and febrile neutropenia between groups. There were more dose reductions and dose delays in the CROSS group than in the CF group (11.3% vs. 3.1%, p = 0.026 and 34.0% vs. 17.5%, p = 0.009, respectively). The resection rate was 52.6% in the CF-RT and 35.1% in the CROSS groups (p = 0.014). CONCLUSION: Favorable PFS and pCR rates and a comparable OS were obtained with the CROSS regimen over the CF regimen as neoadjuvant chemoradiotherapy in patients with ESCC.

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.

AIMS: To evaluate the efficacy and safety of docetaxel plus oxaliplatin and capecitabine (XLOT) in the treatment of locally advanced and metastatic gastric adenocarcinoma. METHODS AND MATERIAL: A total of 32 locally advanced gastric cancer (LAGC) and metastatic gastric cancer (MGC) patients in between 2019 to 2021 were enrolled into this study. Patients received XLOT regimen (docetaxel 50 mg/m2 and oxaliplatin 85 mg/m2 intravenous infusion on day 1, and capecitabine 2000 mg/day (day 1-14) orally. Treatment was repeated every three weeks. STATISTICAL ANALYSIS USED: Statistical data analysis was performed using the Special Package for the Social Sciences (SPSS) version 25.0 for Windows (SPSS Inc., Chicago, Illinois, USA). The Kaplan-Meier method was used for analyses of PFS and OS, and the two survival curves were compared using the log-rank test. A Chi-square test was used to compare independent group ratios. P values of < 0.05 were accepted as statistically significant. RESULTS: The median age of 32 patients was 59.5 (26-79) years. The median cure count was 5 (1-11), and the median follow-up duration was 7 (3-19) months. The numbers of patients with compelete responsens (CRs), partial responses (PRs), stable disease (SD), and progressive disease (PD) were 6 (18.8%), 19 (59.4%), 5 (15.6%), and 2 (6.3%), respectively. The objective response rate (ORR) was 78.2%, with the disease control rate (DCR) of 93.8%. Median progression free survival (mPFS) and overall survival (mOS) were 11.7 (9.6-13.9) and 18.9 (15.4-22.3) month, respectively. The most common grade 3/4 toxicities were hematological toxicities. The most common toxicity was neutropenia which was observed in 18 (56.3%) patients. The most common grade 3/4 nonhematological toxicities were fatigue, nausea, vomiting, diarrhea. CONCLUSIONS: The XLOT regimen demonstrated a promising efficacy as the first-line regimen in treating locally advanced and metastatic gastric cancer patients. Toxicities were tolerated and controllable.

Injuries to the orofacial region may vary from localized injuries to extensive soft and hard tissue loss. In addition to physical and psychologic damages, functional and aesthetic aspects must be restored. This clinical report describes the rehabilitation of a patient with a mandibular defect caused by a gunshot wound. Rehabilitation of this patient, with the use of an overdenture prosthesis, was performed after mandibular surgical hard and soft tissue reconstruction. A maxillary total prosthesis and an implant-supported mandibular overdenture supported by 4 osseointegrated implants were fabricated. Despite limited mouth opening and anatomic deficiencies, the patient's aesthetic and functional demands were fulfilled.

BACKGROUND: Small bowel adenocarcinomas (SBAs) are rarely seen tumors. Data regarding the use of chemotherapy together with bevacizumab in patients with advanced SBA are lacking. The aim of this study was the evaluation of treatment with bevacizumab in advanced SBA. MATERIALS AND METHODS: Twenty-eight patients from 5 centers with a diagnosis of advanced SBA who received first-line treatments with modified FOLFOX6 (mFOLFOX6; oxaliplatin, leucovorin, and 5-fluorouracil) and FOLFIRI (leucovorin, 5-fluorouracil, and irinotecan) chemotherapy regimens were involved in the study. All patients were divided into 2 groups; those who received bevacizumab together with these chemotherapy regimens (Chemo+Bev group) and those who did not receive bevacizumab (Chemo group). RESULTS: The median progression-free survival (PFS) and overall survival (OS) times of all population were 8.7 months and 16.9 months, respectively. The overall response rate was 43.7% in the Chemo group and 58.3% in the Chemo+Bev group. The median PFSs in the Chemo and Chemo+Bev groups were found to be 7.7 months and 9.6 months, respectively, and the median OSs were 14.8 months and 18.5 months, respectively. There was not a significant difference between the groups in terms of overall response rate, PFS, and OS. CONCLUSION: Although there was no significant difference in any of the outcomes, use of bevacizumab together with chemotherapy is a more effective treatment approach compared with chemotherapy alone, and it does not cause an excess of significant toxicity.
