Background: The aim of this retrospective study was to assess the value of 18 F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography ([ 18 F]FDG PET/CT parameters in cN1-cN3 non-small cell lung cancer (NSCLC) patients., Materials and Methods: 59 consecutive patients (35 M, 24 F) with NSCLC who underwent pretreatment [ 18 F]FDG PET/CT were enrolled to this study. Several primary tumor PET parameters, including the maximum and mean standardized uptake value (SUV max and SUV mean) , the metabolic active tumor volume (MTV) and the total lesion glycolysis (TLG = MTVxSUV mean ), were extracted and analysed. Overall survival was defined as time from primary diagnosis to death or the last info., Results: In the whole analysed group 44 patients underwent curative treatment, while 15, because of the severity of the disease, were classified for palliative treatment. Univariate Cox analysis of clinical and metric PET parameters revealed that MTV was a significant prognostic factor for OS (p = 0.024), while TLG and curative treatment showed a trend for significance (p < 0.1). In multivariate Cox regression (MTV and curative treatment) MTV remained a significant factor (p = 0.047)., Conclusions: Metabolic tumor volume of the primary tumor was the only independent prognostic factor for cN1-cN3 NSCLC patients., Competing Interests: Conflicts of interest: Authors declare no conflict of interest., (© 2024 Greater Poland Cancer Centre.)

Background: Aim of this study was to evaluate the rate of incidental detection of second primary cancer (SPC) at 18F-fluorocholine ([18F]FCH) positron emission tomography/computed tomography (PET/CT) performed in prostate cancer patients., Material and Methods: A retrospective analysis was performed on a group of 1345 prostate cancer patients, who underwent [18F]FCH PET/CT study because of suspicion of recurrence (n = 937) or for initial staging (n = 408). Images were acquired after intravenous injection [18F]FCH with a mean activity of 200 ± 75 MBq (5.4 ± 2 mCi), from the top of the head to the half of the thigh. The confirmation of second primary cancer was obtained from the cancer registry., Results: Based on the [18F]FCH PET/CT scans, a second primary cancer was suspected in 89 patients (6.6%). Of these, a malignancy was histologically confirmed in 26 patients (29% of all suspected findings and 1.9% of the complete cohort). Lung cancer (including adenocarcinoma, neuroendocrine cancer) was diagnosed in 13 patients (50%) and hematologic neoplasm (including chronic lymphocytic leukemia, Hodgkin lymphoma, follicular lymphoma, and multiple myeloma) in 5 patients (19%). 18F-fluorocholine PET/CT also revealed esophageal cancer, mesothelioma, testicular, renal, bladder, and colorectal cancer inindividual patients, non-keratinizing squamous cell carcinoma (SCC) of the skin as well as head and neck SCC with unknown primary., Conclusion: We conclude that incidental detection of a second primary cancer in prostate cancer patients using [18F]FCH PET/CT is not very common and that lung cancer and hematologic malignancies are most frequently detected.

Background: The aim of the study was to compare the TNM classification with 2-[ 18 F]FDG PE T biological parameters of primary tumor in patients with NSCLC., Materials and Methods: Retrospective analysis was performed on a group of 79 newly diagnosed NSCLC patients. PET scans were acquired on Gemini TF PET/CT scanner 60-70 min after injection of 2-[ 18 F]FDG with the mean activity of 364 ± 75 MBq, with the area being examined from the vertex to mid-thigh. The reconstructed PET images were evaluated using MIM 7.0 Software for SUV max , MTV and TLG values., Results: The analysis of the cancer stage according to TNM 8 th edition showed stage IA2 in 8 patients, stage IA3 - 6 patients, stage IB - 4 patients, IIA - 3 patients, 15 patients with stage IIB, stage IIIA - 17 patients, IIIB - 5, IIIC - 5, IVA in 7 patients and stage IVB in 9 patients. The lowest TLG values of primary tumor were observed in stage IA2 (11.31 ± 15.27) and the highest in stage IIIC (1003.20 ± 953.59). The lowest value of primary tumor in SUV max and MTV were found in stage IA2 (6.8 ± 3.8 and 1.37 ± 0.42, respectively), while the highest SUV max of primary tumor was found in stage IIA (13.4 ± 11.4) and MTV in stage IIIC (108.15 ± 127.24)., Conclusion: TNM stages are characterized by different primary tumor 2-[ 18 F]FDG PET parameters, which might complement patient outcome., Competing Interests: Conflict of interest None declared., (© 2021 Greater Poland Cancer Centre.)

25 patients with neurological and neuropsychological deficits after a mild ischaemic stroke were treated with nicergoline (Adavin 60 mg/d) versus placebo in a double blind cross-over trial (3 and 3 months). The patients were examined repeatedly by a neurologist and a neuropsychologist using a battery of tests (PPL, AVLT, Benton and Bourdon tests, number-repetition test). On completion of the trial the improvement of neurological signs (mainly cerebellar deficits) and neuropsychological impairments (in particular of attention and manual manipulation difficulties) was found to be more marked after the period of nicergoline treatment than after placebo. No drug-dependent side effects--including the influence on blood pressure--were observed in the whole group treated.

On the basis of an analysis of documentation from hospital the annual rate of first admissions for cerebrovascular disturbances was assessed in the population of the city district of Warsaw. The total rate was 123/100 000, including 22 for subarachnoid and cerebral haemorrhage. The rate was highest in the age group over 70 years (1162/100 000). The annual average death rate caused by these disease was 94/100 000. In the first month after admission 41% of patients died (including 77% with the diagnosis of cerebral haemorrhage) and during 6 months 52% died. The diagnosis of cerebrovascular disturbances was mentioned in only about 75% of death certificates of patients dying within one month from admission. In the Wrasaw population the annual rate of first admission and average annual death rate were on the average 1.5 times higher than the mean values for the whole country. Difficulties with the use of medical documentation for epidemiological studies are discussed.
