“I’m the Decider! (Is That OK with You?)”
Today, after reviewing a CT scan (and screwing my courage to the sticking-place) I went into an exam room, looked a patient in the eye and said: “The liver lesions have started to grow again. I think we need to change your treatment.”
ConclusionPatients with pancreatic cancer with a tumor SUVmax ≥ 7.05 or a CA 19-9 value ≥ 240.55 are likely to have lymph node micrometastases.
Conclusion There is no research on the intraobserver agreement analysis of 68Ga–prostate-specific membrane antigen positron emission tomography/computed tomography in the literature. Our findings are the first ones. The intraobserver agreement was almost perfect. Moreover, although 68Ga–prostate-specific membrane antigen I&T positron emission tomography/computed tomography had moderate interobserver evaluation compliance of the primary tumour, it had excellent interobserver agreement levels in local lymph node metastasis and distant metastasis evaluation.4012501255
Objective Patients with prostate cancer are monitored by prostate-specific antigen (PSA) evaluation and PET [PET/computed tomography (CT)]. The aim of our study was to evaluate correlations between PSA levels and standardized uptake values (SUV) in patients with recurrent prostate cancer. Methods We analyzed 282 prostate cancer patients undergoing PET-CT due to suspicion of recurrence. Levels of PSA and PSA change per month were analyzed, together with maximum standardized uptake value (SUVmax). Results PET/CT results were positive in 175 patients (62.1%) and negative in 107 patients (37.9%). In the positive group,...
ConclusionsThe current study includes the largest number of patients analyzed to date and demonstrates that ADT causes a significant decrease in serum PSA values and SUVp and SUVln. The authors demonstrate that68Ga-PSMA-PET/CT may be used as a quantitative imaging modality after neoadjuvant ADT in hormone-na ïve non-metastatic PC patients.
Abstract The application of image processing techniques for the analysis of CT scan images corresponding to lung cancer cells is gaining momentum in recent years. Therefore, it is of interest to discuss the use of a Computer-Aided Diagnosis (CAD) system using Computed Tomography (CT) images to help in the early diagnosis of lung cancer (to distinguish between benign and malignant tumors). We discuss and explore the design and significance of a CAD-CT image processed model in cancer diagnosis. PMID: 31719770 [PubMed]
ConclusionThe PET/CT-based radiomic features showed good performance in predicting EGFR mutation in non-small cell lung cancer, providing a useful method for the choice of targeted therapy in a clinical setting.
ConclusionsBevacizumab intrapleural infusion had higher efficiency and higher safety than intravenous infusion in the management of malignant pleural effusion caused by NSCLC. The decreased level of serum VEGF at 72 hours after bevacizumab treatment was closely related to the response rate and duration of the response of pleural effusion.
Authors: Gulak MA, Bornais C, Shin S, Murphy L, Smylie J, Pantarotto JR, Fung-Kee-Fung M, Maziak DE Abstract Background: Patients with lung cancer often experience stressful delays throughout the diagnostic phase of care. To address that situation, our multidisciplinary team created a "Navigation Day," during which patients partake in a single-day visit that comprises nurse-led teaching, social work, smoking cessation counselling, symptom control, and dedicated test slots for integrated positron-emission tomography and computed tomography (pet/ct), pulmonary function tests (pfts), and magnetic resonance i...
AbstractBackgroundPancreatic cancer induces parenchymal atrophy and duct dilation. The aim of this study was to evaluate whether these radiologic modifications are associated with outcomes.MethodsUpfront pancreaticoduodenectomy patients with available preoperative contrast enhanced CT scan imaging were retrospectively analyzed. Thickness of the pancreas, size of the main pancreatic duct (MPD), and distance of the tumor from the ampulla were assessed. A training cohort was selected, including short- (3 –12 months following surgery) and long-term (≥ 36 months) survivors. Identified survival determin...
A 50-year-old woman presented with stomach discomfort. The patient had undergone a lobular breast cancer (LBC) surgery 17 years previously. On physical examination, mild upper abdominal tenderness was detected. Laboratory tests did not show any notable findings. Abdominal computed tomography scan revealed a gastric wall thickening (Fig. 1A, arrow). Esophagogastroduodenoscopy showed diffuse hypertrophic gastric folds (Fig. 1B). Biopsy specimens from the folds showed a poorly differentiated adenocarcinoma (Fig.
