OBJECTIVE We investigated the outcomes of radiotherapy (RT) combined with systemic chemotherapy (CHT) including carboplatin and paclitaxel in patients with locally advanced non-small-cell lung cancer. METHODS This retrospective study included 105 patients. Treatment involved concurrent carboplatin and paclitaxel with RT administered weekly followed by two cycles of consolidation carboplatin and paclitaxel administered triweekly. RESULTS Comorbid disease was present in 46 (48.6%) patients. At least four cycles of CHT in the concurrent phase and both cycles of CHT in the consolidation phase were able to be administered to 92.3% and 45.4% of patients, respectively. The most common type of toxicity in the entire treatment protocol was hematological toxicity (34.8%). The objective response rate was 71.4%. Overall, recurrence was found in 71 (67.6%) patients. The most common type of recurrence was distant metastasis, which occurred in 47 (66.2%) patients. The median progression-free survival was 14 months. The 1, 2, and 3-year progression-free survival rates were 59%, 30%, and 26%, respectively. The median overall survival was 27 months. The 1, 2, and 3-year overall survival rates were 81%, 57%, and 34%, respectively. CONCLUSION The survival outcomes in this study closely match those reported in the literature. This is notable because our study included a higher proportion of patients with additional health conditions and fewer concurrent CHT cycles during RT compared to randomized studies. These findings prompt us to consider what the ideal number of concurrent CHT cycles should be when using modern involved-field RT techniques after accurate disease staging. [ABSTRACT FROM AUTHOR]

OBJECTIVE: We compared the survival outcomes of surgery within multimodality treatment regimens with the outcomes of definitive chemoradiation treatments in patients diagnosed with clinical (c) IIIB/N2 non-small cell lung cancer (NSCLC). We investigated whether surgery within multimodality treatment provides a survival advantage at this stage. MATERIAL AND METHODS: Data from 79 patients with cIIIB/N2 between 2009 and 2016 were analyzed retrospectively. While the surgery was performed after neoadjuvant therapy in 51 cases (IIIB/Surgery Group), definitive chemotherapy ± radiotherapy was applied in 28 cases (IIIB/Definitive Group). RESULTS: In cIIIB/N2 cases, the 5-year overall survival (OS) was 27.4%, with a median OS of 24.6 months. The 5-year OS of the IIIB/ Surgery Group was 27.3% (median survival 22.5 months), while it was 28.6% (median survival 29.1 months) in the IIIB/Definitive Group (P = .387, HR = 0.798, 95% CI, 0.485-1.313). Although there was a survival advantage in the group with a pathological complete response (PCR) after surgery (n = 14) compared to the group that did not (n = 37), the observed difference was not statistically significant. (5-year OS; 42.9% vs. 18.5%, P = .104). Additionally, there was no statistically significant difference between the survival of PCR patients and the IIIB/Definitive Group in terms of OS (P = .488). CONCLUSION: Surgery performed within multimodality treatment regimens in selected cIIIB/N2 cases did not provide a survival advantage over definitive chemoradiation treatments.

Objectives: More than half of gastric cancer patients have no chance of resection at the time of diagnosis. In gastric cancer, which has increased frequency with age, chemotherapy efficacy and tolerability in metastatic gastric cancer aged 75 and over have been investigated due to the fact that the elderly patient population is not sufficiently involved in the studies. Methods: In our study, the clinical and demographic characteristics of patients, treatment regimens and responses, prognostic factors, grad 3-4 toxicity, progression-free survival (PFS) and overall survival (OS) were examined. Results: In the study involving 118 patients, PFS was 5.8 months and OS was 8.4 months. A disease control rate of 38.1% was achieved with chemotherapy. Conclusion: Since the OS in this study was 10.5 months in patients with ECOG PS 0-1, 13.8 months in patients who received two lines or more, and the frequency of side effects was acceptable, we believe that this patient population should not be left untreated. Since there are acceptable survival values even with single-agent therapies, monotherapy can be recommended for patients with poor ECOG PS and combination therapies can be recommended for patients with good PS without comorbidities.

Objectives: In cases where homologous recombination repair (HRR) gene analysis is performed, platinum-based chemotherapy is better than other chemotherapy regimens. FOLFIRINOX is the regimen of choice for first-line treatment of pancreatic cancer. However, it is a toxic regimen, and not all patients can tolerate this treatment. Because HRR genes are frequently detected in pancreatic cancer and because FOLFIRINOX treatment cannot be applied to every patient, platinum-based therapies can be used as a first-line therapy. For this reason, we conducted this study to show the firstline effect of a platinum-gemcitabine combination for the treatment of metastatic pancreatic cancer. Methods: This retrospective and multicenter study included patients admitted to five centers in Turkey between 2010 and 2017. The inclusion criteria were as follows: patients older than 18, diagnosed with metastatic pancreatic cancer, with no previous local treatment (surgery or radiotherapy), with no chemotherapy for metastatic disease, and with an ECOG performance score of 0-2. Results: A total of 217 patients were included in the study. Of these, 103 were administered gemcitabine alone, and 114 were administered gemcitabine plus cisplatin/carboplatin. Overall survival was significantly longer in the gemcitabine-cisplatin/carboplatin group than in the gemcitabine alone group (9.8 months vs. 5.2 months; p<0.001). Likewise, progression-free survival was statistically significantly longer in the gemcitabine-cisplatin/carboplatin group than in the gemcitabine alone group (4.9 months vs. 3.2 months; p<0.001). Conclusion: In cases where HRR gene analysis cannot be performed during the treatment of patients with metastatic pancreatic cancer, a patient who cannot tolerate FOLFIRINOX can be treated with a combination of cisplatin/carboplatin-gemcitabine as a first-line treatment. However, larger prospective studies are needed to confirm its effectiveness. [ABSTRACT FROM AUTHOR]

Simple Summary: Despite advances in treatment generated by clinical trials in metastatic breast cancer (MBC), their impact on routine daily practice and the reflection of the outcome within the community remains unclear. This study evaluates time-related differences in treatment patterns and outcome in a real-world patient population with MBC over a ten-year timeframe. Except for the HER2+ subgroup, which showed a significant survival benefit with the incorporation of novel agents, we failed to identify significant variations in outcomes for the remaining subgroups. A consistent feature we observed was the challenge in treating TNBC, which had the worst prognosis in both time-related cohorts. Elucidation of biologic characteristics to identify novel treatment options remains an unmet need to improve outcomes in TNBC. The favorable survival attained with routine endocrine agents in the luminal A subgroup suggests that barriers in access to CDK inhibitors may not have a negative impact on the outcome in subgroups of hormone receptor-positive patients, constituting an appealing strategy for communities with limited resources. This multicenter registry study aims to analyze time-related changes in the treatment patterns and outcome of patients with metastatic breast cancer (MBC) over a ten-year period. Correlations between demographic, prognostic variables and survival outcomes were carried out in database aggregates consisting of cohorts based on disease presentation (recurrent vs. de novo) and the diagnosis date of MBC (Cohort I: patient diagnosed between January 2010 and December 2014; and Cohort II: between January 2015 and December 2019). Out of 1382 patients analyzed, 52.3% patients had recurrent disease, with an increased frequency over time (47.9% in Cohort I vs. 56.1% in Cohort II, p < 0.001). In recurrent patients, 38.4% (n = 277) relapsed within two years from initial diagnosis, among which triple-negative BC (TNBC) was the most frequent (51.7%). Median overall survival (OS) was 51.0 (48.0–55.0) months for all patients, which was similar across both cohorts. HER2+ subtype had the highest OS among subgroups (HER2+ vs. HR+ vs. TNBC; 57 vs. 52 vs. 27 months, p < 0.001), and the dnMBC group showed a better outcome than recMBC (53 vs. 47 months, p = 0.013). Despite the lack of CDK inhibitors, luminal A patients receiving endocrine therapy had a favorable outcome (70 months), constituting an appealing approach with limited resources. The only survival improvement during the timeframe was observed in HER2+ dnMBC patients (3-year OS Cohort I: 62% vs. Cohort II: 84.7%, p = 0.009). The incorporation of targeted agents within standard treatment has improved the outcome in HER2+ MBC patients over time. Nevertheless, despite advances in early diagnosis and treatment, the prognosis of patients with TNBC remains poor, highlighting the need for more effective treatment options. [ABSTRACT FROM AUTHOR]

OBJECTIVE It is known that cancer patients are more prone to infections than the general population. We aimed to describe the risk factors affecting the survival of cancer patients infected with COVID-19 and clinical findings compared with a large COVID-19 patient population without cancer diagnosis. METHODS The clinical data of 61 cancer and 558 non-patients with COVID-19 infection who applied to the emergency room were compared retrospectively. Risk factors affecting overall survival in cancer patients were analyzed. RESULTS Gender and mean age were comparable in both groups. In the entire cohort, cancer diagnosis was found to be an independent poor prognostic factor (hazard ratio [HR] = 3.09, p<0.001) among other comorbidities. In univariate analysis; lung cancer, activated partial thromboplastin time >32 seconds, INR >1.1, N-terminal-pro-B-type natriuretic peptide (NT-proBNP) >400 pg/ml, C-reactive protein >100 mg/L, and procalcitonin >0.23 ng/mL were determined as prognostic risk factors. Lung cancer (HR=5.277, p=0.012) and NT-proBNP >400 pg/ml (HR=0.139, p=0.021) were determined as independent prognostic risk factors in multivariate analysis. CONCLUSION Cancer patients with COVID-19 infection have poor survival outcomes. Lung cancer diagnosis and elevated NT-proBNP levels were identified as the most crucial prognostic risk factors in cancer patients infected with COVID-19. [ABSTRACT FROM AUTHOR]

Background: Cancer is a significant health problem for refugees and host countries. Breast cancer is the most common cancer among refugees. The subject of our study is to examine the clinical and pathological features of Syrian refugees with breast cancer and compare them with Turkish patients with breast cancer. Methods: Data of patients with breast cancer between January 2018 and December 2020 were retrospectively reviewed. The clinical and histological features, treatment modalities and overall survival were collected and analyzed. Results: A total number of 338 women with breast cancer were included in this study. Ninety-nine of the 338 (29.3%) patients were Syrian refugees and 239 patients (70.7%) were Turkish. The median follow-up time was significantly lower in Syrian patients (P < 0.001). Median OS was 146 months in Turkish and 116 months in Syrian group (P = 0.022). Independent risk factors associated with long survival were receiving adjuvant chemotherapy (HR 0.465; 95% CI 0.234-0.926; P = 0.029), adjuvant radiotherapy (HR 0.372 95% CI 0.182-0.758; P = 0.007), and adjuvant hormonotherapy (HR 0.367; 95% CI 0.201-0.669; P = 0.001). The rates of receiving adjuvant chemotherapy, adjuvant radiotherapy, and adjuvant hormonal therapy were significantly lower in the Syrian group (P = 0.023, P = 0.005, P = 0.002, respectively). Conclusion: Syrian refugees with breast cancer are more likely to receive suboptimal treatments. They have inferior survival compared to local patients. Our findings highlight the need for the provision of cancer therapy in such vulnerable populations. We suggest that more attention should be paid to breast cancer, as it is the most common cancer among refugees. [ABSTRACT FROM AUTHOR]

Objective: Cytokines have been the mainstay of treatment in metastatic renal cell cancer (mRCC) for decades before the introduction of tyrosine kinase inhibitors (TKIs), which dramatically changed the therapeutic landscape in these patients. This observational study was designed to evaluate use of TKIs in the treatment of cytokine-intolerant mRCC patients. Methods: A total of 151 cytokine-intolerant mRCC patients who were treated with TKIs (sunitinib, pazopanib and sorafenib) were enrolled in this prospective, non-interventional, multi-center observational study at 16 oncology centers across Turkey. Mean (SD) age was 61.3 (11.1) years and 74.8% were males. Data on duration of TKI treatment was the primary outcome measure. Additionally, overall response rate (ORR), progression free survival (PFS), overall survival (OS) and safety data were recorded. Results: Median duration of treatment was 8.2 months at a median follow up of 17.9 months. ORR and disease control rate were 12.5% and 70.8%, respectively. Median PFS and OS were 7.5 months (95%CI: 6.4–10.4) and 27.3 months (95%CI: 17.6–27.3) with no significant difference among three TKI agents in terms of treatment duration, ORR, PFS and OS. The most common adverse events excluding progression-which was the protocol requirement were diarrhea (13.6%), asthenia (13.6%) and hand-foot syndrome (12.6%). Dose modifications were required in 30.5% of the patients and 15% discontinued TKIs because of toxicity. Conclusions: Our findings confirm the efficacy and safety profile of TKIs in the first-line treatment of mRCC patients intolerant to cytokine treatment. There was no significant difference among three TKI agents in terms of treatment duration, ORR, PFS and OS. Trial registration: TURCOS ClinicalTrials.gov Identifier: NCT01585974.
