RESUMO
OBJECTIVE: The objective of this multi-centre, real-world study was to examine the potential influence of comprehensive molecular profiling on the development of treatment decisions or adjustments for patients with advanced solid malignancies. We then evaluated the impact of these informed choices on patient treatment outcomes. METHODS: The study encompassed 234 adult patients (mean age: 52.7 ± 14.3 years, 54.7% women) who were diagnosed with solid tumours at 21 different medical centres in Turkey. Remarkably, 67.9% of the patients exhibited metastasis at the time of diagnosis. We utilized an OncoDNA (Gosselies, Belgium) platform (OncoDEEP) integrating next-generation sequencing with additional tests to harvest complex molecular profiling data. The results were analyzed in relation with two specific outcomes: (i) the impact on therapeutic decisions, including formulation or modifications, and (ii) associated treatment response. RESULTS: Out of the 228 patients with final molecular profiling results, 118 (50.4%) had their treatment modified, whilst the remaining 110 (47.0%) did not. The response rates were comparable, with 3.9 versus 3.4% for complete response, 13.6 versus 29.3% for partial response, 66.9 versus 51.7% for progressive disease and 15.5 versus 15.5% for stable disease for treatments informed and not informed by complex molecular profiling, respectively (P = 0.16). CONCLUSION: Our real-world findings highlight the significant impact of complex molecular profiling on the treatment decisions made by oncologists for a substantial portion of patients with advanced solid tumours. Regrettably, no significant advantage was detected in terms of treatment response or disease control rates.

AIM: To investigate the pathological complete response (pCR) achieved after neoadjuvant therapy with versus without adding pertuzumab (P) to trastuzumab (H) plus neoadjuvant chemotherapy (NCT) in HER2+ breast cancer (BC) patients in a real-life setting. METHODS: A total of 1528 female HER2+ BC patients who received NCT plus H with or without P were included in this retrospective real-life study. Primary endpoint was pCR rate (ypT0/Tis ypN0). Clinicopathological characteristics, event-free survival (EFS) time, and relapse rates were evaluated with respect to HER2 blockade (NCT-H vs. NCT-HP) and pCR. RESULTS: Overall, 62.2% of patients received NCT-H and 37.8% received NCT-HP. NCT-HP was associated with a significantly higher pCR rate (66.4 vs. 56.8%, p < 0.001) and lower relapse (4.5 vs. 12.2%, p < 0.001) in comparison to NCT-H. Patients with pCR had a significantly lower relapse (5.6 vs. 14.9%, p < 0.001) and longer EFS time (mean(SE) 111.2(1.9) vs. 93.9(2.7) months, p < 0.001) compared to patients with non-pCR. Patients in the NCT-HP group were more likely to receive docetaxel (75.0 vs. 40.6%, p < 0.001), while those with pCR were more likely to receive paclitaxel (50.2 vs. 40.7%, p < 0.001) and NCT-HP (41.5 vs. 32.1%, p < 0.001). Hormone receptor status and breast conservation rates were similar in NCT-HP vs. NCT-H groups and in patients with vs. without pCR. Invasive ductal carcinoma (OR, 2.669, 95% CI 1.596 to 4.464, p < 0.001), lower histological grade of the tumor (OR, 4.052, 95% CI 2.446 to 6.713, p < 0.001 for grade 2 and OR, 3.496, 95% CI 2.020 to 6.053, p < 0.001 for grade 3), lower T stage (OR, 1.959, 95% CI 1.411 to 2.720, p < 0.001) and paclitaxel (vs. docetaxel, OR, 1.571, 95% CI 1.127 to 2.190, p = 0.008) significantly predicted the pCR. CONCLUSIONS: This real-life study indicates that adding P to NCT-H enables higher pCR than NCT-H in HER2+ BC, while pCR was associated with lower relapse and better EFS time.

BACKGROUND: In vitro studies have shown that the functional - 1478CA > del polymorphism (rs33989964) of the suppressor of cytokine signaling (SOCS)-1 gene is associated with an altered trascriptional activity. Here, we sought to examine the potential association of this polymorphism with the risk of gastric cancer (GC) and to analyze its prognostic impact on overall survival (OS). MATERIALS AND METHODS: The study cohort consisted of 74 Turkish patients with GC and 52 healthy controls. Genotyping of the SOCS-1 -1478CA > del polymorphism was carried out using restriction fragment length polymorphism analysis. RESULTS: After allowance of age and sex, multivariable logistic regression analysis revealed that the carriage of the del allele of the SOCS-1 -1478CA > del polymorphism was independently associated with an increased risk of GC (odds ratio = 6.78, 95% confidence interval = 3.24-10.99, P < 0.001). Kaplan-Meier analysis revealed no significant differences in OS for patients harboring at least one del allele of rs33989964 compared with CA/CA homozygotes (log-rank test, P = 0.17). CONCLUSION: While the SOCS-1 -1478CA > del polymorphism is significantly associated with the risk of GC in the Turkish population, it does not affect OS.

BACKGROUND: Oligometastatic disease for nonsmall cell lung cancer (NSCLC) patients is generally thought to represent a better prognosis with a quieter biology, limited number of disease sites and long-term disease control. In this study, we aimed to determine the efficacy of radical treatment options for patients with oligometastatic NSCLC. METHODS: This retrospective trial included totally 134 patients with oligometastatic NSCLC. The presence of oncodriver mutation, tumor stages and nodal status, the number of metastases and involved metastatic site, treatment of primary tumor and oligometastasis, response rate, overall survival (OS) and progression-free survival (PFS) were evaluated. RESULTS: Of 134 patients 66.4% were defined as adenocarcinoma, 26.1% were squamous cell carcinoma and 7.5% of patients were in other histology. Based on the treatment of primary tumor, in 36 patients (26.9%) curative surgery has undergone, in addition, 19 (14.2%) patients were received chemotherapy, 73 (54.5%) were treated with chemoradiotherapy, while immunotherapy and targeted therapy were used in 1 (0.7%) and 2 (1.4%), respectively. The preferred treatment for oligometastatic lesions were SBRT in 72.4% of patients, surgery in 10.5%, and both SBRT and surgery in 17.1% of patients. At the median follow up of 31.3 months (range: 9.5-48.5), the median PFS and OS times were 17 and 24.4 months, respectively. Moreover, OS-2 after progression was also 7.2 months. DISCUSSION: Based on our real-life experience, we demonstrated a significant correlation between good response to first treatment and survival in oligometastatic disease, we also understand that local ablative treatment modalities prolong and also delay both OS and PFS in oligometastatic NSCLC patients OS-2.

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.

The aim of this study was to investigate the predictive value of PLR and NLR as an indicator of pathological complete response (pCR) in patients with breast cancer after NACT. One hundred thirty-nine patients with early or LABC and candidates to NACT were retrospectively analyzed. The prognostic significance of PLR and NLR was analyzed. In addition, predictive indicators of pCR to NACT were also evaluated. pCR was obtained in 48.9% of patients. Significant difference was detected between pCR and PLR, tumor grade, clinical lymph node status and molecular subgroup. The higher rate of pCR was significantly achieved for patients with PLR low ( < 181.7) compared with those with PLR high (>181.7) (68.6% vs. 33.4%; P < 0.001). PLR, tumor grade and pCR to NACT for disease-free survival (DFS), and PLR, NLR, tumor grade and pCR to NACT for overall survival were detected to be prognostic factors by univariate analysis. On the other hand, a logistic regression analysis indicated that PLR and NLR were found to be an independent factors for predicting pCR to NACT ( P < 0.001; OR, 0.07; 95% CI, 0.02-0.25 and P = 0.016; OR, 4.66; 95% CI, 1.33-16.2, respectively), as were molecular subtypes ( P = 0.001; OR, 0.23; 95% CI, 0.09-0.56). Our results showed that PLR low and NLR low before NACT are readily feasible and simple and also inexpensive biomarkers predicting pCR to NACT for patients with LABC.

BACKGROUND: Atezolizumab (ATZ) has demonstrated antitumor activity in previous studies in patients with metastatic platinum-resistant urothelial carcinoma. However, the response rate of ATZ was modest. Therefore, finding biologic or clinical biomarkers that could help to select patients who respond to the immune checkpoint blockade remains important. PATIENTS AND METHODS: In this study, we present the retrospective analysis of 105 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. Data of patients were obtained from patient files and hospital records. The association between response to first-line chemotherapy and ATZ was using Fisher's exact test. Median follow-up was calculated using the reverse Kaplan-Meier method. OS was estimated by using the Kaplan-Meier method. RESULTS: The median follow-up time was 23.5 months. Forty (74.1%) of patients who experienced clinical benefit after firs-line chemotherapy also had clinical benefit after atezolizumab, while only 14 (25.9%) of patients with initial PD after first-line chemotherapy subsequently experienced clinical benefit with ATZ (p = 0.001). The median OS on ATZ of 14.8 and 3.4 months for patients with clinical benefit and progressive disease in response to first-line chemotherapy, respectively (p = 0.001). Three of the adverse prognostic factors according to the Bellmunt criteria were independent factors of short survival: liver metastases {Hazard ratio [HR] = 1.9; p = 0.04}, ECOG PS ≥ 1 (HR = 2.7; p = 0.001), and Hemoglobin level below 10 mg/dl (HR = 2.8; p < 0.001). In addition, patients with clinical benefit from first-line chemotherapy (HR = 0.39; p < 0.001) maintained a significant association with OS in multivariate analysis. CONCLUSIONS: Our study demonstrated that clinical benefit from first-line chemotherapy was independent prognostic factors on OS in patients' use of ATZ as second-line treatment in metastatic bladder cancer. Furthermore, these findings are important for stratification factors for future immunotherapy study design in patients with bladder cancer who have progressed after first-line chemotherapy.

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

BACKGROUND: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies of patients with metastatic platinum-resistant urothelial carcinoma. However, the response rate of Atezolizumab was modest. In the current study, we evaluated the pretreatment prognostic factors for overall survival in patients with metastatic urothelial carcinoma who have progressed after first-line chemotherapy in the Expanded-Access Program of Atezolizumab. PATIENTS AND METHODS: In this study, we present a retrospective analysis of 113 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. Data of the patients was obtained from patient files and hospital records. Eligible patients included metastatic urothelial carcinoma patients treated with at least one course of ATZ. Univariate analysis was used to identify clinical and laboratory factors that significantly impact OS. Variables were retained for multivariate analysis if they had a statistical relationship with OS (p < 0.1), and then included a final model of p < 0.05. RESULTS: The median follow-up duration was 23.5 months. Of the patients, 98 (86.7%) were male and 13.3% were female. The median age was 65 years of age (37-86). In univariate analysis, primary tumor location in the upper tract, increasing absolute neutrophil count (ANC), increasing absolute lymphocyte count, neutrophil-to-lymphocyte ratio (NLR) > 3, liver metastases, baseline creatinine clearance less (GFR) than 60 ml/min, Eastern Cooperative Oncology Group (ECOG) performance status (1 ≥), and hemoglobin levels below 10 mg/dl were all the significantly associated with OS. Three of the five adverse prognostic factors according to the Bellmunt criteria were independent of short survival: liver metastases HR 3.105; 95% CI 1.673-5.761; p < (0.001), ECOG PS (1 ≥) HR 2.184; 95% CI 1.120-4.256; p = 0.022, and Hemoglobin level below 10 mg/dl HR 2.680; 95% CI 1.558-4.608; p < (0.001). In addition, NLR > 3 hazard ratio [HR] 2.092; 95% CI 1.031-4.243; p = 0.041 and GFR less than 60 ml/min HR 1.829; 95% CI 1.1-3.041; p = 0.02, maintained a significant association with OS in multivariate analysis. CONCLUSIONS: This model confirms the Bellmunt model with the addition of NLR > 3 and GFR less than 60 ml/min and can be associated with clinical trials that use immunotherapy in patients with bladder cancer.
RESUMO
Paraneoplastic neurological syndrome is associated with anti-Ri antibodies, which are typically present with opsoclonus-myoclonus-ataxia. Human epidermal growth factor receptor 2 (HER2) overexpression is present in 15%-25% of breast cancer and is associated with poor prognosis. There are a few reports of paraneoplastic neurological syndrome associated with HER2-positive breast cancer in the literature, of which most are anti-Yo-associated paraneoplastic neurological syndrome. We present herein the case of a female patient with HER2-positive breast cancer who had atypical anti-Ri antibody associated with opsoclonus-myoclonus paraneoplastic neurological syndrome. Following the diagnosis of paraneoplastic syndrome, chemotherapy with dual HER2 blockade and immunomodulating treatment including intravenous immunoglobulin and oral prednisolone were administered. Although the patient was negative for serum anti-Ri antibodies, there was partial clinical improvement and her neurological deficit persisted. To our knowledge, this is the first case report of female patient with HER2-positive breast cancer who had atypical anti-Ri antibody associated with opsoclonus-myoclonus paraneoplastic neurological syndrome and treated with dual HER2 blockade.

PURPOSE: To investigate whether the pretreatment neutrophil lymphocyte ratio (NLR) and the platelet lymphocyte ratio (PLR) have any prognostic significance in patients with HER2-positive early breast cancer receiving adjuvant trastuzumab. METHODS: 187 patients were retrospectively analyzed. The patients were separated into two groups according to the mean value of NLR and PLR (low NLR≤2.38, high NLR>2.38; and low PLR≤161.28, high PLR>161.28, respectively). The relationship between pretreatment NLR, PLR and clinicopathological factors was investigated. Univariate and multivariate Cox regression analyses were performed. To evaluate survival rates, the Kaplan-Meier method with log rank test were used. RESULTS: The median duration of follow up was 26.0 months (range 6.0-84.0). In high NLR and PLR groups, the mean age was lower, tumor size was larger and the number of hormone receptor positive patients was higher. No statistically significant relationship was found between clinicopathological factors and both NLR and PLR groups. During follow up, the rate of relapse was 12.6% in the low NLR group, 16.2 % in the high NLR group, 12.6% in the low PLR group and 15.8% in the high PLR group (p=non significant). Although median disease free survival (DFS) was shorter in the high NLR than in the low NLR group, the difference was not statistically significant (p=0.45). No statistically significant difference was found between high and low PLR groups with regard to median DFS and overall survival (OS) (p=0.76, p=0.29, respectively). CONCLUSION: We conclude that in HER2-positive early breast cancer patients receiving adjuvant trastuzumab with high pretreatment NLR, DFS was shorter. As for PLR, no effect either on DFS or on OS was registered. Prospective studies with larger number of patients are required in order to evaluate the prognostic effect of NLR and PLR in HER2-positive breast cancer patients.

INTRODUCTION: Triple-negative breast cancers (TNBCs) - which lack the expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) - have no established markers that can be used for prognostic stratification. As adiponectin has been previously implicated in a more aggressive phenotype of primary breast cancer, we explored the relation between adiponectin immunohistochemical expression and prognosis in TNBCs. MATERIAL AND METHODS: Immunohistochemical staining for adiponectin was performed in 38 TNBC patients. Disease-free survival (DFS) and overall survival (OS) served as the main outcome measures. RESULTS: Of the 38 TNBC patients, 18 (47%) had negative and 20 (53%) positive adiponectin immunohistochemical expression. We did not find any significant association between adiponectin immunohistochemical expression and the baseline characteristics. In addition, there were no associations between adiponectin immunohistochemical expression and prognosis. CONCLUSIONS: Although our results suggest that adiponectin immunohistochemical expression is not of prognostic significance in TNBCs, further studies are warranted to determine the role of this adipokine in breast cancer biology.
RESUMO
BACKGROUND: This study aimed to evaluate the utility of RECIST criteria-based objective response rate (ORR) as a potential surrogate endpoint for long-term overall survival (OS) in patients with metastatic urothelial carcinoma who were treated with immune checkpoint inhibitors (ICIs). METHODS: The primary endpoint was overall ORR and OS, duration of treatment (DoR) with ICIs. ORR was analyzed using Fisher's exact test. Median follow-up and OS were estimated by using the Kaplan-Meier method. RESULTS: The median follow-up was 58 (1.15-71) months. Progression developed in 94 (47%) patients during the first 3 months of ICIs therapy. The treatment response to ICIs included complete response (CR), partial response (PR) and stable disease in 10% (n = 20), 23% (n = 46), and 20% (n = 41) of patients, respectively. The responder and nonresponder groups differed in terms of certain baseline characteristics, such as Bellmunt risk factors, and neutrophil-to-lymphocyte ratio (NLR). The 5-year OS rates for patients with CR and PR were 73% and 23%, respectively. The median DoR for CR, PR, and SD were 51.8 months (44.5-59.1), 20.7 months (16.7-24.6), and 8.8 months (5.5-12.1), respectively. Overall, 16(80%) patients with CR and 14(30%) patients with PR had an ongoing response at the time of the analysis. In the univariate analysis, NLR > 3, liver metastases, ECOG PS ≥ 1, and hemoglobin levels < 10 mg/dl, as well as the PR and CR, were all significantly associated with OS. In multivariate analysis, presence of liver metastases (HR 2.3; 95% CI, 1.3-4.2; P < .004) was found to be an independent determinant of short OS, while PR (HR 0.3; 95% CI, 0.15-0.5; P < .001) and CR (HR 0.06; 95% CI, 0.014-0.27; P < .001) were associated with improved OS. CONCLUSIONS: In conclusion, this 5-year analysis of real-world data in the setting of metastatic urothelial cancer indicated a significant correlation between ORR, especially CR, and OS in patients who received ICIs. Therefore, identifying a potential surrogate marker for survival in patients treated with ICIs would represent an important advance in the early identification of patients' response or resistance to ICIs.
RESUMO
BACKGROUND: Prostate cancer is a prevalent cancer in men worldwide, and castration-resistant prostate cancer (CRPC) is characterized by disease progression despite androgen deprivation therapy. While clinical and prognostic biomarkers have been identified in CRPC, the significance of serum inflammatory markers remains unclear. MATERIALS AND METHODS: This retrospective study included 79 CRPC patients treated with abiraterone or enzalutamide. Inflammatory markers, including the modified Glasgow prognostic score (mGPS), systemic immune-inflammation index (SII), and neutrophil-to-lymphocyte ratio (NLR), were assessed as predictive tools for treatment response. Patient data were obtained from medical charts, and statistical analyses were performed. RESULTS: The median age of the patients was 67 years, with most having a Gleason score of 8-10. The median values for NLR, PLR, and SII were 2.9, 168.5, and 713.5, respectively. The objective response rate (ORR) to abiraterone or enzalutamide therapy was 55.1%. mGPS showed a significant association with ORR, with the mGPS 0 group having the highest response rate (59.5%). Median progression-free survival (PFS) was 12.8 months, and median overall survival (OS) was 35.4 months. Palliative radiotherapy during therapy and PSA doubling time were independent prognostic factors for PFS. CONCLUSIONS: mGPS and PSA doubling time significantly impacted survival, and mGPS significantly predicted the treatment response in mCRPC, which may lead to further prospective studies.

The current study was designed to assess the response to treatment, as well as clinical and survival outcomes, across different breast cancer subtypes in patients who underwent neoadjuvant chemotherapy (NAC). From 2014 to 2019, a total of 139 patients who were histologically confirmed to have breast cancer, underwent NAC, and subsequently received breast and axillary surgery, were retrospectively included in this study. The rates of pathological complete response (pCR) to NAC were significantly higher for HER2-positive and triple-negative subtypes than for luminal A and HER2-negative subtypes (p = 0.013). Multivariate analysis for disease-free survival (DFS) revealed that tumour grade and the presence of pCR were independent prognostic factors. The presence or absence of a pCR with NAC was an independent prognostic indicator in the multivariate analysis for overall survival (OS). Lastly, achieving a pCR was independently predicted by 18F-FDG PET/CT findings, the HER2-positive subtype, and the triple-negative subtype. Despite the inherent methodological limitations, our findings underscore the significance of identifying predictive markers to tailor NAC plans, with the aim of improving survival outcomes.
RESUMO
Loss of human epidermal growth factor receptor 2 (HER2) expression can be seen in almost 25-30 % patients after HER2 receptor directed neoadjuvant treatment. These patients have unclear clinical outcomes in previous studies. We aimed to investigate the importance of HER2 loss, additionally with predictive factors for the loss of HER2. This was a retrospective and multicenter study that included 272 HER2-positive BC patients with no pathological complete response who received neoadjuvant chemotherapy plus HER2-targeted treatments. The factors that may affect the loss of HER2 detected by immunohistochemistry(IHC) and the association with survival were analyzed.The rate of HER2 loss after neoadjuvant treatments(NAT) was 27.9 % (n = 76). Disease recurrence was observed in 18(23.7 %) patients with HER2 loss, while it was detected in 62 (31.7 %) patients without HER2 loss(p = 0.23). Pre and post-NAT ER status, and post-NAT ki-67 status had a significant impact on disease-free survival(DFS) (p = 0.0012, p = 0.004, and p = 0.04, respectively).There were no significant association between DFS and loss of HER2 (p = 0.64) and dual anti-HER2 blockade (p = 0.21). Pre-NAT clinical stage (HR:1.65 p = 0.013), post-NAT LN status (HR:3.18, p = 0.02) and pre-NAT ER status (HR:0.24, p = 0.041) were significant independent prognostic factors for DFS while post-NAT residual disease in axillar tissue was an independent prognostic factor for OS (HR:1.54 p = 0.019). Moreover, age (<40 years vs ≥40 years) (p = 0.031) and tumor grade (p = 0.004) were predictive factors for HER2 loss. Our results showed that HER2 loss did not affect survivals. However, young age and being high grade tumor may predict HER2 loss.

We evaluated the incidence, clinicopathological features, prognostic factors, progression-free survival (PFS) and overall survival (OS) of patients with gastric cancer and bone metastases. The medical records of 110 patients with bone metastases were retrospectively analyzed. In our study, the incidence of bone metastases was 3.2%. The median patient age was 60 years. A total of 68 (61.8%) patients exhibited synchronous metastases, and 42 (38.2%) patients developed metachronous metastases. Alkaline phosphatase (ALP) levels were high in 54 (49%) patients. At the median follow-up time of 9.8 months, median PFS and OS times were 4.7 and 6.3 months, respectively. The median interval from the diagnosis to bone metastases was 9.3 months. Univariate analysis showed that Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≥2, stage at diagnosis, time of metastases, number of metastases, presence of extraskeletal metastases, use of zoledronic acid treatment, palliative chemotherapy post-bone metastases and radiotherapy to bone metastases were significant prognostic indicators for PFS. Additionally, ECOG PS ≥2, stage at diagnosis, time of metastases, number of metastases, presence of extraskeletal metastases, zoledronic acid treatment, palliative chemotherapy post-bone metastases, and radiotherapy to bone metastases significantly influenced OS. Moreover, in multivariate analysis, ECOG PS, time of metastases, presence of extra-bone metastases, and the use of palliative chemotherapy after bone metastases were found to be independent prognostic factors for PFS. Moreover, ECOG PS, time of metastases, and use of palliative chemotherapy after bone metastases were significantly independent prognostic indicators for OS. Our findings show that the presence of synchronous metastases, use of palliative chemotherapy, use of zoledronic acid after bone metastases, and ALP level within the normal range were significantly associated with prolonged OS in gastric cancer patients with bone metastases.
RESUMO
Based on the CheckMate 649 trial, nivolumab plus chemotherapy is the recommended first-line treatment for HER2-negative unresectable advanced or metastatic gastric, gastroesophageal junction (GEJ), or esophageal adenocarcinoma. This nationwide, multicenter, retrospective study evaluated the real-world effectiveness of this regimen in Turkish patients and identified subgroups that may experience superior outcomes. Conducted across 16 oncology centers in Turkey, this study retrospectively reviewed the clinical charts of adult patients diagnosed with HER2-negative unresectable advanced or metastatic gastric, GEJ, or esophageal adenocarcinoma from 2016 to 2023. This study included 111 patients (54 women, 57 men) with a median age of 58 years. The median progression-free survival (PFS) and overall survival (OS) were 11.7 months and 18.2 months, respectively, whereas the objective response rate (ORR) was 70.3%. Multivariable analyses revealed that previous curative surgery was a favorable independent prognostic factor for both PFS and OS. Conversely, an Eastern Cooperative Oncology Group performance status of 2 emerged as an adverse independent prognostic factor for OS. The safety profile of nivolumab plus chemotherapy was found to be manageable. Our findings support the use of nivolumab plus chemotherapy for the first-line treatment of Turkish patients with HER2-negative unresectable advanced or metastatic gastric, GEJ, or esophageal adenocarcinoma. Patient selection based on clinical characteristics is crucial for optimizing treatment outcomes.
RESUMO
BACKGROUND: Triple negative breast cancer (TNBC) is characterized by high rates of recurrence, especially in patients with residual disease after neoadjuvant chemotherapy (NAC). Capecitabine is being used as standard adjuvant treatment in residual TNBC. We aimed to investigate the real-life data regarding the efficacy of capecitabine in residual TNBC. DESIGN AND METHODS: In this retrospective multicenter study, TNBC patients with residual disease were evaluated. Patients, who received standard anthracycline and taxane-based NAC and adjuvant capecitabine were eligible. Overall survival (OS), disease free survival (DFS) and toxicity were analyzed. RESULTS: 170 TNBC patients with residual disease were included. Of these, 62.9% were premenopausal. At the time of analysis, the recurrence rate was 30% and death rate was 18%. The 3-year DFS and OS were 66% and 74%, respectively. In patients treated with adjuvant capecitabine, residual node positive disease stood out as an independent predictor of DFS (p = 0.024) and OS (p = 0.032). Undergoing mastectomy and the presence of T2 residual tumor was independent predictors of DFS (p = 0.016) and OS (p = 0.006), respectively. CONCLUSION: The efficacy of capecitabine was found lower compared to previous studies. Selected patients may have further benefit from addition of capecitabine. The toxicity associated with capecitabine was found lower than anticipated.
