Background: One-third of patients with colorectal cancer (CRC) are likely to have a recurrence within the first 1-2 years. Conventional imaging modalities have limitations in detecting recurrent disease early. The purpose of this study was to assess the usefulness of fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in the detection of recurrence in patients with CRCs.
Methods: One hundred and eighty-three patients, who were earlier treated with surgery and/or chemotherapy/radiotherapy, underwent 269 PET/CT studies for the detection of recurrence. The final diagnosis was made on the basis of histological analysis or clinical and imaging follow-up.
Results: The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value in detecting recurrent CRC using F-FDG-PET/CT were 87, 90, 88, 93, and 80%, respectively. PET/CT was found to have limitations in detecting microscopic disease and small-sized lesions. The common cause of false-positive PET/CT results was infective and inflammatory pathology in our setup.
Conclusion: PET/CT showed high sensitivity, specificity, and accuracy for the detection of recurrent disease in patients, who were earlier treated for CRC. PET/CT can be considered as a useful diagnostic tool in these patients.

Therapeutic hurdles persist in the fight against lung cancer, although it is a leading cause of cancer-related deaths worldwide. Results are still not up to par, even with the best efforts of conventional medicine, thus new avenues of investigation are required. Examining how immunotherapy, precision medicine, and AI are being used to manage lung cancer, this review shows how these tools can change the game for patients and increase their chances of survival.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) placement leads to a reduction in portal pressure and an improvement in survival in patients with recurrent and refractory ascites and variceal haemorrhage. Prediction of post-TIPS survival is primarily determined by factors identified before the TIPS procedure, as data collected during or after TIPS implantation are limited. The aim of the study was to evaluate the influence of early hemodynamic changes after TIPS placement on survival, in order to refine post TIPS management.

Background: Few population-based studies have assessed sex differences in stroke recurrence. In addition, contributors to sex differences in recurrence and poststroke mortality, including social factors, are unclear. We investigated sex differences in these outcomes and the contribution of social, clinical, and behavioral factors to the sex differences.

In the present case, a 66-year-old woman presented to the Specialty Hospital (Amman, Jordan) with recurrent post-menopausal bleeding. A pelvic ultrasound scan showed an abnormal endometrial thickness of 8 mm and no adnexal masses. An endometrial biopsy revealed abundant foamy histiocyte infiltration features suggestive of xanthogranulomatous endometritis.
