Background/Objectives This study aimed to evaluate whether very early interim 18F-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/computed (CT) after a single cycle of first-line chemotherapy predicts long-term survival outcome in patients with diffuse large B-cell lymphoma (DLBCL). Methods A total 51 (31 males and 20 females; mean age 55 years) had four FDG PET/CT studies, at baseline one, three, six cycles (PET0, PET1, PET3, PET6). Visually quantitatively assessed PET...
Abstract Purpose: Traditional methods, fine-needle aspiration cytology (FNAC) and washout thyroglobulin (Tg), do not always provide sufficient accuracy for diagnosing lymph node (LN) metastasis in thyroid cancer. This study aimed to validate the diagnostic performance of cytokeratin fragment 21-1 (CYFRA 21-1) as a complementary biomarker metastatic LNs cancer explore its relationship with molecular analysis distant metastasis. Patients Methods: In this retrospective cohort involving 230 224...
Abstract Background This study investigated the frequency of diabetic gastroparesis and associated risk factors in a real-world clinical setting. Methods retrospective cross-sectional included patients who underwent assessments solid gastric emptying time (GET) by technetium-99 m scintigraphy between May 2019 December 2020. We categorized into three groups according to retention m: rapid (< 65% at 1 h or < 20% 2 h), normal (≤60% and/or ≤ 10% 4 delayed (> 60% > h). Results...
This paper aimed to evaluate the prognostic value of maximum standardized uptake (SUVmax) and metabolic tumor volume (MTV) primary on 18 F-FDG PET/CT scan in early stage non-small cell cancer (NSCLC) patients without lymph node (LN
Fine needle aspiration cytology (FNAC) and washout thyroglobulin (Tg) measurements are the standard for evaluating a metastatic lymph node (LN) in thyroid cancer. However, patients rarely benefit from these procedures due to false results. This study aims identify reliable biomarker that significantly improves diagnosis of LNs, addition FNAC Tg. analyzed 130 LNs were suspected have metastases on ultrasonography, June 2016 December 2017. All subjects underwent FNAC, Tg new biomarker,...
We investigated the prognostic role of metabolic parameters from preoperative 18F-FDG PET/CT in stage II/III colorectal adenocarcinoma. A total 327 adenocarcinoma patients who underwent curative resection were included. The maximal standard uptake value (SUVmax), tumor volume (MTV), and lesion glycolysis (TLG) analyzed for optimal cut-offs their effect on DFS. Differences DFS rates hazard ratios between statistically significant SUVmax, MTV2.5, MTV3, TLG 2.5, TLG3, TLG30%. Factors...
The most common manifestation of multiple endocrine neoplasia type 1 (MEN1) is hyperparathyroidism. Treatment hyperparathyroidism in MEN patients surgical removal the parathyroid glands, however ectopic gland challenging for treatment. A 51-year-old female, eldest 3 MEN1 sisters, had with adenoma mediastinal para-aortic region, which was detected by technetium-99m (Tc-99m) sestamibi scintigraphy and single-photon emission computed tomography/computed tomography (SPECT/CT). She underwent...
Background: Epstein-Barr virus-associated gastric cancer (EBVaGC) is one of the four molecular subtypes cancer, as defined by classification recently proposed The Cancer Genome Atlas. We evaluated correlation between EBV positivity and <sup>18</sup>F-fluorodeoxyglucose (<sup>18</sup>F-FDG) uptake positron emission tomography/computed tomography (PET/CT) in patients with cancer. Materials Methods: retrospectively enrolled who underwent pretreatment <sup>18</sup>F-FDG PET/CT subsequent...
A 51-year-old man was diagnosed with small cell lung cancer (SCLC) brain, left adrenal gland, and pancreas metastases. On evaluation of treatment response after chemotherapy radiation therapy, F-18 FDG PET/CT showed focal uptake in the periappendiceal area thickened appendiceal wall inflammatory change. Laparoscopic appendectomy done, findings were consistent acute suppurative appendicitis involvement 2 masses on body tip. Histopathologic confirmed metastatic carcinoma, involving submucosa,...
This study was performed to determine the frequency and patterns of obstructive colitis (OC) seen on F-FDG PET/CT scan patients with adenocarcinoma colon rectum.Preoperative scans surgical records 308 surgically proven colorectal were retrospectively reviewed for presence obstruction OC proximal adenocarcinoma. The distributions, patterns, SUVmax evaluated PET/CT. Abdominal CT, colonoscopic finding, histopathologic findings specimen also reviewed.Of patients, 29 (9.4%) showed OC. mean 3.6 ±...
We report the case of a 36-year-old woman who previously underwent total thyroidectomy for papillary thyroid carcinoma. F FDG PET/CT images demonstrated multiple lymph nodes with increased uptake in neck, chest, and abdomen diffusely spleen, which were highly suspicious findings malignant lymphoma. However, subsequent biopsy axillary node presented reactive hyperplasia. Detailed history revealed that patient had generalized edema severe arthralgia after contact ginkgo nut one week ago. This...
Abstract Background Despite the widespread use of F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in diagnosis and response assessment patients with lymphoma, few studies have assessed its value ocular adnexal lymphomas. The purpose this study was to evaluate role FDG PET/CT staging non-conjunctival origin mucosa-associated lymphoid tissue (MALT) lymphomas (OAML). In addition, diagnostic sensitivity compared magnetic resonance imaging (MRI). 123...
