Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study

PURPOSEThe clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.METHODSThis retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson’s chi-squared test, the Fisher–Freeman–Halton test, and Fisher’s exact test were used for the statistical analyses.RESULTSThe overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSIONADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision

Assessment of prognostic factors and adjuvant treatment modalities in adult head and neck soft tissue sarcoma patients treated with upfront surgery

ObjectivesHead and neck soft tissue sarcomas (HNSTSs) are a heterogeneous group of rare tumors. Surgical resection with negative margins remains the standard primary treatment for patients with HNSTS. The role of chemotherapy (CT) and radiotherapy (RT) remains controversial. In this multicenter study, we aimed to demonstrate the real-world assessing prognostic factors and the effect of adjuvant treatment modalities in adult patients with HNSTS treated with upfront surgery.MethodsWe included a total of 47 patients who underwent curative-intent resection of a primary HNSTS between 2000 and 2019.ResultsThe median follow-up was 29 months. The median age of patients was 51 years, and 66% of patients were male. The median relapse-free survival (RFS) of the study population was 31 months (range: 1.0-61.1 months), and the median overall survival (OS) was 115 months (range: 60.8-169.2 months). The univariable analysis revealed that treatment modalities showed a significant impact on RFS (p = 0.021); however, no difference was found in its impact on OS (p = 0.137). R0 resection did not showed impact on RFS (p = 0.130), but a significant association was found with OS (p = 0.004). In multivariable analysis, T stage of the tumor (hazard ratio [HR]: 3.834; 95% CI: 1.631-9.008; p = 0.002) and treatment with surgery and sequential RT and CT (HR: 0.115; 95% CI: 0.035-0.371; p < 0.001) were independent factors associated with RFS. R0 resection was independently associated with OS (HR: 4.902; 95% CI: 1.301-18.465; p = 0.019).ConclusionOur study revealed that R0 resection improved OS, and T3-4 stage of tumor was a negative independent factor for RFS in surgically resected HNSTS patients. The use of sequential CT and RT after resection was associated with a better RFS, which emphasizes the importance of multidisciplinary evaluation of the treatment of HNSTS. Randomized prospective studies are needed

Cetuximab-induced rash is associated with overall survival in patients with recurrent/metastatic squamous cell carcinoma of head and neck

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

Factors affecting survival in retroperitoneal sarcomas treated with upfront surgery: A real-world study by Turkish Oncology Group

Retroperitoneal sarcomas (RPS) account for approximately 15% of all soft tissue sarcomas (STS) and encompass a heterogeneous group of tumors with limited multimodality treatment options. Surgical resection with negative margins remains the standard primary treatment for patients with localized RPS. In this multicenter study, we aimed to demonstrate the real-world data on factors affecting survival in RPS treated with upfront surgery. We included a total of 197 patients who underwent curative-intent resection of a primary non-metastatic RPS between 2000-2020 at ten experienced medical oncology departments in Turkey. The median follow-up was 33 months. The median age of patients was 53 years, 57.4% of patients were female. Univariate analysis revealed that; tumor size, grade, necrosis, resection margin status, were factors affecting recurrence-free survival (RFS) (p= 0.002, p= 0.044, p= 0,024, p= 0.003 respectively). Age, tumor size, stage, resection margin status were factors affecting overall survival (OS) (p= 0.038, p= 0.001, p= 0.032, p< 0.001, respectively). In multivariate analysis, tumor size and resection margin status were independent factors affecting RFS and OS (all p-values < 0.05). Our study demonstrated that tumor size, and resection margin status were the main factors affecting survival in resected RFS. In comparison, adjuvant chemotherapy (CT), radiotherapy (RT), or multimodality treatment did not show OS and RFS advantages. We believe that advances in the molecular characterization of these tumors might help clinicians to detect the best candidates for adjuvant therapies in RPS

Evaluation of the efficacy and safety of nivolumab in the second- or later-line treatment of patients with locally advanced/metastatic non-small cell lung cancer in Türkiye: a retrospective multicenter non-interventional registry study

ObjectiveTo evaluate the efficacy and safety of nivolumab in the second-line (2L) or later-line (LL) treatment of patients with locally advanced/metastatic non-small cell lung cancer (NSCLC) in real-life setting in T ; uuml;rkiye.MethodsThis study was designed as a national, multi-center, retrospective study. The study population was evaluated in two groups for the line of nivolumab therapy: those receiving nivolumab in the 2L (Group 2L) and third-line (3L) or LL (Group 3L/LL). Efficacy was evaluated based on one-year overall survival (OS) and progression-free survival (PFS). Safety was evaluated based on treatment-related adverse events (AEs) and nivolumab discontinuation rate.ResultsOf 244 patients, 52.9% were in Group 2L and 47.1% were in Group 3L/LL. Demographic and clinical characteristics did not differ between the groups. In Group 2L and Group 3L/LL, one-year OS and PFS rates were 60.8% and 61.4% (p = 0.592) and 31.2% and 21.3% (p = 0.078), respectively. The objective response rate (ORR) was 34.7% in Group 2L and 27.3% in Group 3L/LL (p = 0.262). The percentage of patients reporting at least one AE in Groups 2L and 3L/LL was 34.9% and 43.5%, respectively (p = 0.169). Fatigue was the most common (16.4%) treatment-related AE in each group. The groups were comparable regarding the AE frequency. Nivolumab was discontinued in 61 patients in Group 2L and 53 patients in Group 3L/LL, with the most common reason being disease progression (57.4% and 66.0%, respectively).ConclusionNivolumab is safe and effective in the 2L or 3L/LL treatment of locally advanced/metastatic NSCLC and associated with acceptable AEs in real-life setting. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer (around 85% of all lung cancers). Patients with NSCLC are usually diagnosed at advanced or metastatic stages. When cancer cells spread to other areas from where they first formed, it is called metastatic cancer. Surgery may not be a treatment option for such patients. Currently, immunotherapeutic agents are used in the treatment of NSCLC. Nivolumab is one of the approved immunotherapeutic agents in the treatment of patients with metastatic NSCLC, who have failed after receiving chemotherapy. Our study explored the efficacy and safety of nivolumab in real-life setting in T ; uuml;rkiye. Nivolumab effectiveness was evaluated by overall survival (OS) and progression-free survival (PFS) rates. OS indicates the proportion of patients who are still alive at a given time after diagnosis or treatment initiation. PFS refers to the length of time during and after cancer treatment that a person lives with the disease but does not get worse. In the present study, one-year OS for 244 patients who received nivolumab was 61.1% and one-year PFS was 26.4%. Nivolumab safety was evaluated based on the frequency of adverse events observed during nivolumab therapy. Of the patients 38.9% had at least one side effect, with fatigue being the most common (16.4%). Our results support the earlier studies and showed that nivolumab was a safe and effective agent and is associated with acceptable side effects.BMS TurkiyeThis study was supported by BMS Turkiy

Cisplatin plus paclitaxel and bevacizumab versus carboplatin plus paclitaxel and bevacizumab for the first-line treatment of metastatic or recurrent cervical cancer

OBJECTIVE: Cisplatin-paclitaxel and bevacizumab is a frequently used treatment regimen for metastatic or recurrent cervical cancer, and carboplatin-paclitaxel and bevacizumab are also among the recommended regimens. In this study we aimed to evaluate the efficacy of these two regimens for the treatment of metastatic or recurrent cervical cancer. METHODS: Patients with metastatic or recurrent cervical cancer treated with cisplatin-paclitaxel and bevacizumab or carboplatin-paclitaxel and bevacizumab were retrospectively evaluated in this study. The clinical and demographic characteristics of patients in each group were evaluated. Median overall survival, progression-free survival, and response rates between the two groups were compared. RESULTS: A total of 250 patients were included. Overall, the numbers of patients with recurrent disease and metastatic disease were 159 and 91, respectively. The most common histologic subtype was squamous cell carcinoma (83.2%). The median duration of follow-up was 13.6 (range 0.5-86) months. The median progression-free survival was 10.5 (95% CI 9.0 to 11.8) months in the cisplatin-paclitaxel and bevacizumab group (group 1), and 10.8 (95% CI 8.6 to 13.0) months in the carboplatin-paclitaxel and bevacizumab group (group 2) (HR 1.20; 95% CI 0.88 to 1.63; p=0.25). The median overall survival was 19.1 (95% CI 13.0 to 25.1) months in group 1 and 18.3 (95% CI 15.3 to 21.3) months in group 2 (HR 1.28; 95% CI 0.91 to 1.80; p=0.15). CONCLUSIONS: There is no survival difference between cisplatin or carboplatin combined with paclitaxel and bevacizumab in metastatic or recurrent cervical cancer
