Blokhin NMRCO to establish capabilities of PET/CT with 18F-FDG and 18F-PSMA-1007 in primary and recurrent ccRCC diagnostics.Material and methods: Forty-eight patients were included in the study, 28 with renal masses and 20 with suspected local recurrence of ccRCC. Biopsy results were available in all patients. All patients underwent PET/CT with 18F-PSMA-1007 and 18F-FDG.Results: Thirty-nine renal neoplasms were identified in 28 patients. 24 of 39 foci (21 patients) were PSMA-positive and 18 of 39 foci (16 patients) were FDG-positive. No false-positive foci were identified. The sensitivity, specificity, positive and negative predictive value in primary RCC were: for 18F-PSMA-1007 — 75, 100, 100 and 85 %, respectively; for 18FDG — 57, 100, 100 and 76 %, respectively. The SUVmax level of 18F-PSMA-1007 exceeded 18FDG in 27 of 28 patients (38 foci); the tumor/background ratio was higher in 16 of 28 patients (24 foci). Tumor thrombosis was detected in 6 patients (PSMA-positive 6 of 6, FDG-positive 5 of 6). PSMA-SUVmax levels in thrombi exceeded 18FDG in all patients, tumor/background ratio in 5 out of 6 patients. Local recurrence was detected in 13 of 20 patients (27 foci). 10 foci in the remaining 7 patients were considered as false positives. No false-negative results were obtained. Sensitivity, specificity, positive and negative predictive value in the diagnosis of local recurrence of ccPCC: 18F-PSMA-1007 — 100, 94, 81 and 100 %, respectively; 18FDG -100, 89, 68 and 100 %, respectively.SUVmax and tumor/background ratio were found to correlate with primary tumor and recurrent node sizes for both RPs.Discussion and conclusions: At the moment, the role of 18F-PSMA-1007 in RCC diagnostics has not been defined. We can note the high efficiency of this RP in the assessment of the primary focus and recurrence of ccRCC, its usage is justified in cases, when routine diagnostic methods do not give an unambiguous answer.The possibilities of 18F-PSMA-1007 in metastatic ccRCC diagnostics are of the greatest interest. A significant prospective material has been collected in our department, which will be the basis for further study of this RP in the diagnostics of metastatic ccRCC.","PeriodicalId":502542,"journal":{"name":"Journal of oncology: diagnostic radiology and radiotherapy","volume":" 33","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141679791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The criterion for selecting patients was a morphologically confirmed on­cological diagnosis and the presence of lesions in the lungs. Patients were recruited from two large groups of leading localizations in the general structure of cancer incidence: a group of patients with colorectal cancer — 76 (54.7 %) and a group of patients with malignant breast tumors — 63 (45.3 %). A total of 312 lung lesions were identified and analyzed in 139 patients. High-resolution computed tomography with a slice thickness of up to 1-1.5 mm of the chest was performed in all patients. Assessment of dynamics in all patients was carried out for at least 3 years.Results: As a result, out of 139 patients with newly detected lesions in the lungs, 43 (30.9 %) patients had lesions identified, which we classified as intrapulmonary regional lymph nodes (RLNs). A total of 75 (24.0 %) lesions classified as typical or atypical RLNs were identified. We obtained the following data: RLNs were located predominantly in the lower lobes — 46.7 %, 84 % of RLNs were localized below the carina. A total of 37.3 % of lesions were classified as perifissural lesions, 62.7 % of identified lesions were classified as subpleural (peripleural) lesions. It was found that the RLNs were localized on the pleura or had a connection with it through a thin septum — 49.3 % and 38.7 %, respectively. The average diameter of the RLN in the lung was 4.0 mm. RLNs were triangular in shape in 64 %, round (lenticular) in 21.3 %, and oval in 14.7 % of cases. 96 % of the lesions we classified as RLN were monitored over time using HRCT for 3 years or more, 4 % of the lesions underwent surgical treatment. All the lesions that we observed over the course of 3 years remained without dynamics. Based on the data obtained, we concluded that RLNs in patients with solid tumors of extrapulmonary locations and lesions in the lungs are benign changes and do not require dynamic monitoring.Conclusions: Lesions in patients with solid tumors of extrapulmonary localization classified as RLN are benign changes and do not affect the stage and nature of the treatment, and also do not require dynamic monitoring.","PeriodicalId":502542,"journal":{"name":"Journal of oncology: diagnostic radiology and radiotherapy","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141678586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breast cancer (BC) is the most common malignant tumor in women worldwide. It amounts more than 16 % of all cases of malignant neoplasms in women. Modern advances in radiological methods of breast tumors detection significantly increased the number of non-palpable neoplasms revealed during examinations, while further progress requires the development of improved minimally invasive techniques for obtaining biopsy material from breast tumors using tools of navigational controls. An approach with high potential for direct evaluation of local tumor metabolism consists in complementary use of fluorescence spectroscopy and diffuse reflectance spectroscopy.Purpose: Evaluation of the effectiveness of a new complementary approach for the diagnosis of the metabolic status of breast tumors in patients suspicious for breast cancer.Material and methods. This article presents the results of the examination of 21 patients with breast neoplasms who, in addition to standard examination methods, including ultrasound, X-ray mammography, puncture biopsy and trepanobiopsy, were subject to evaluation of local tumor metabolism with complementary employment of fluorescence spectroscopy and diffuse reflectance spectroscopy .Results. It has been established that the malignant breast tumors have lower saturation values compared with both benign tumors and the surrounding healthy tissue: StO2(BC) = 6,6 % [5,7-24,8 %]; 79,0 % [77,6-84,4 %], StO2(fibroadenoma) = 66,3 %[43,7-74,8 %]. It is also found that the malignant tumors have higher values of NADPH compared with the benign tumors (INAD(P) H(BC) = 6157 a.u. [2188-8814 a.u.]; INADH (fibroadenoma) = 2962 a.u. [1924-4301 a.u. ]).Conclusion. The new method of the diagnosis of the local breast tumor metabolism can be further used to improve the results of targeted biopsies under ultrasound control and to assess the therapeutic pathomorphosis of BC. To evaluate the effectiveness of this diagnostic method, it is necessary to continue the study with a larger number of patients in order to obtain statistically reliable data.","PeriodicalId":502542,"journal":{"name":"Journal of oncology: diagnostic radiology and radiotherapy","volume":" 42","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141679384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
