Background: Thrombosis in the pulmonary vein stump (PVS) is not a well-known complication after pulmonary lobectomy, but it has the potential to cause embolism to vital organs. The aim of this study was to evaluate the risk factors for thrombosis in the PVS after pulmonary lobectomy.
Methods: A total of 439 patients who underwent pulmonary lobectomy from 2008 to 2017 were retrospectively reviewed, and 412 patients were further analyzed. The state of the PVS was evaluated by chest contrast-enhanced computed tomography (CECT). Univariate analysis was performed to evaluate the potential risk factors for thrombosis in the PVS.
Results: Thrombosis in the PVS was detected in 6 of 412 (1.5%) patients, and 5 of them underwent left upper lobectomy (LUL) (5/100, 5.0%) (P = 0.004). In the analyses of the LUL group, postoperative chest radiotherapy was identified as a risk factor for thrombosis in the PVS (P = 0.024), and postoperative atrial fibrillation showed a tendency to be a risk factor for thrombosis (P = 0.058).
Conclusions: Chest radiotherapy after LUL is a possible risk factor for thrombosis in the PVS. Periodic chest CECT is recommended after postoperative chest radiotherapy for patients after LUL.

Metastatic Sclerosing Epithelioid Fibrosarcoma at Diagnosis: A Case Report.

Sclerosing epithelioid fibrosarcoma (SEF) is a rare and aggressive neoplasm composed of epithelioid cells arranged in strands and nests embedded in a highly sclerotic collagenous stroma. We report a case of a 36-year-old man who started with lumbar pain, with extension to both legs, night sweats, and weight loss. He underwent magnetic resonance imaging (MRI) of the lumbar spine; computed tomography (CT) scan of the chest, abdomen, and pelvis; and [18F]-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan.

It has been popular and challenging to undertake researches on the delay of acquired resistance of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI). As key cells for tumor initiation, cancer stem cells (CSC) play an important role in the process of resistance to EGFR-TKI. Although preliminary studies found that traditional Chinese medicine (TCM) could inhibit CSC properties and delay EGFR-TKI resistance, the specific molecular mechanism remains unclear.

Objective: This study aims to evaluate the efficacy of two free-breathing magnetic resonance imaging (MRI) sequences-spiral ultrashort echo time (spiral UTE) and radial volumetric interpolated breath-hold examination (radial VIBE).
Methods: Patients were prospectively enrolled between February 2021 and September 2022. All participants underwent both 3T MRI scanning, utilizing the radial VIBE sequence and spiral UTE sequence, as well as standard chest CT imaging.

Purpose: To contrast breast radiation exposure from chest radiotherapy in 2006-2021 with 1965-1997, and to compare breast cancer (BC) risk 25 years after treatment predicted by two models.
Methods: Radiation dose distributions to the breast from 101 chest radiotherapies given 2006-2021 for Hodgkin lymphoma (HL) or other lymphoma in one German and two Dutch hospitals were compared with doses received by 505 Dutch HL patients treated 1965-1997 and sampled into a nested case-control study, weighted to represent a HL patient cohort. Dose-volume histograms, mean dose and doses to 10 breast segments were evaluated.

Introduction: Distant recurrences are a major problem after surgical treatment for endometrial carcinoma; metastases to the bone are usually restricted to the axial skeleton, cases of costal localization are few. We present a case of a massive costal metastases successfully treated in our department.
Case Presentation: A 60-year-old woman underwent bilateral hysteroannessectomy followed by adjuvant radiotherapy for endometrial adenocarcinoma pT3a FIGO IIIA.
