Objective: A high metabolism/perfusion rate in the tumor is known to be factor indicating poor prognosis. The goal of this study was to investigate the prognostic value of the ratio of the conventional standard uptake value to early-phase imaging standard uptake value in patients with newly diagnosed non-small cell lung cancer. Materials and Methods: Early-phase imaging was obtained in the first 120 seconds and conventional imaging was taken after median 66 minutes. The ratio of the conventional standard uptake value to early-phase imaging standard uptake value was calculated. Univariate and multivariate analyses were performed using the Cox proportional hazards regression model to assess the relationship between progression-free survival and ratio of the conventional standard uptake value to early-phase imaging standard uptake. Results: A total of 77 patients with non-small cell lung cancer were recruited. Progression-free survival analysis was performed in 52 inoperable patients. Progression-free survival was found to be related to conventional standard uptake value (p<0.001), tumor size (p<0.001) and ratio of the conventional standard uptake value to early-phase imaging standard uptake in univariate analysis (p=0.047). In the multivariate analysis, ratio of the conventional standard uptake value to early-phase imaging standard uptake (p=0.001, HR=1.145, 95CI%:1.145-1.719) and tumor size (p<0.001, HR=1.026, 95CI%:1.007-1.045) were found to be independent poor prognostic factors. Conclusion: The ratio of the conventional standard uptake value to early-phase imaging standard uptake was found an indicator for prognosis. Evaluating the early phase imaging, without a need for kinetic program or software, without disrupting the routine functioning of the clinic, with conventional imaging may contribute to cancer patient management. There is a need for studies with larger groups of patients.

Background/Aim. About 1.8 million new lung cancer cases are diagnosed in the world every year, and about 1.6 million cases are with fatal outcome. Despite improvements in treatment in previous decades, the survival of patients with lung cancer is still poor. The five-year survival rate is about 50% for patients with localized disease, 20% for patients with regionally advanced disease, 2% for patients with metastatic disease, and about 14% for all stages. The median survival of patients with untreated NSCLC in the advanced stage is four to five months and the annual survival rate is only 10%. The main goal of the research is to obtain and analyze the results of treatment with concomitant chemotherapy in terms of its efficacy and toxicity in selected patients with locally advanced inoperable non-small cell lung cancer. Methods. The study included data analysis of 31 patients of both sexes who were diagnosed and pathohistologically verified with NSCLC in inoperable stage III and were referred by the Council for Malignant Lung Diseases to the Radiotherapy Department of the Military Medical Academy for concomitant chemoradiotherapy treatment. Upon expiry of the three-month period from the performed radiation treatment, the tumor resonance was assessed on the basis of MSCT examination of the chest and upper abdomen according to RECIST 1.1 criteria (Response Evaluation Criteria in Solid Tumors). According to the same criteria, progression-free survival (PFS) was also assessed every three months during the first two years, then every 6 months or until the onset of disease symptoms, as well as overall survival (OS). Result. The median progression-free survival is 13 months, and the median overall survival is 20 months. During and immediately after RT, 9 (29%) patients had a grade 2 or higher adverse event. Conclusion. The use of concomitant chemoradiotherapy in patients in the third stage of locally advanced inoperable non-small cell lung cancer provides a good opportunity for a favorable therapeutic outcome, with an acceptable degree of acute and late toxicity, and represents the standard therapeutic approach for selected patients in this stage of the disease.

e21107 Background: C-Reactive Protein (CRP) is a non-specific inflammatory marker and reflects tissue destruction seen in metastatic cancer (ca). We have observed a tight correlation with CRP trends mirroring ca activity, hence it may prove to be a valuable marker to monitor response to Immuno-Oncology (IO) in non-small cell lung cancer (NSCLC) patients (pts). Once CRP levels stabilized, IO discontinuation was offered, and consenting pts were closely observed. This strategy resulted in shortened IO duration and impressive treatment-free progression-free survival (tf-PFS). We sought to examine the validity of this strategy using the rate of return to any form of ca therapy within 6 months after stopping IO. Methods: We analyzed all pts of a single provider since 2016 with stage IV NSCLC who had CRP checked while on IO, totaling 23 pts. We excluded pts who stopped IO for reasons besides stable CRP values (5 progressed on IO, 3 died while on IO, 1 had side effects, 1 stopped for a clinical trial, 1 opted to complete 2 years of IO, and 2 are still on IO). Of the remaining 10 patient cohort, all pts were males treated at the VA with ages between 56-75 years at diagnosis. 50% of the cohort had adenocarcinoma and 50% had squamous cell carcinoma. Results: Using the CRP trend to shorten the duration of IO resulted in durable drug-free holidays with none of the cohort returning to any form of ca therapy within 6 months and comparable rates of overall survival (OS) despite shorter IO duration. In KEYNOTE-042, the median OS for pts on the pembrolizumab arm was 16.7 months in the overall population and 20 months in the TPS ≥50% subgroup. Pts were treated for up to 35 months. In our cohort, median OS was 38 months, with all pts currently still alive, and median number of doses of IO was 9 cycles, or approximately 7 months. Our pts had ongoing progression free survival (PFS) after stopping treatment, which we report as tf-PFS. The median tf-PFS of our cohort was 23.5 months. Conclusions: In pts with stage IV NSCLC treated with IO, CRP appears promising as a marker to tailor IO therapy addressing tumor and clinical heterogeneity. Responding pts with stable CRP levels can be safely taken off IO. CRP should be monitored with stable values indicating continued PFS. tf-PFS rather than PFS may serve as a surrogate for cure and carries significant impact for pts financially, socially, and psychologically.
