Objective: To compare the ease and effects of collecting blood from cats by use of subcutaneous totally implantable vascular access ports (VAPs) with collection via conventional jugular phlebotomy.
Design: Prospective randomized experimental study.
Animals: 8 healthy cats.
Procedures: Cats in the port group (n = 4) underwent monthly blood donation by use of VAPs and manual restraint, and cats in the nonport group (4) underwent monthly blood donation by use of conventional jugular phlebotomy and sedation, for 6 months.
Results: Postsurgical VAP-related complications developed in 3 cats and included port erosion (n = 1), disconnection of the port from the catheter (1), and seroma formation (1). Blood was successfully collected 24 of 24 and 20 of 20 times in the nonport and port groups, respectively. Results of bacterial culture of blood were negative in 22 of 24 and 15 of 20 nonport and port collections, respectively. No differences in RBC morphology were observed between groups. Mean blood collection and total donation times were significantly longer for the nonport group. Collection time was more variable in the nonport group, and cats were less tolerant of handling during venipuncture, compared with cats in the port group. Blood collection required a mean of 2.4 persons for the nonport group and 2.1 persons for the port group.
Conclusions And Clinical Relevance: Positive results for blood collections via VAPs were increased donor acceptance, decreased number of personnel required, and decreased collection time. Drawbacks included contamination of blood products and port-related complications.

Impact of locoregional recurrence versus distant metastasis on overall survival in patients with Non-Small cell lung cancer after Surgery: A secondary analysis of PORT-C RCT.

Purpose: The therapeutic advantage of postoperative radiation therapy (PORT) for non-small cell lung cancer (NSCLC) has not been shown to benefit overall survival (OS) according to two randomized controlled trials (RCTs), albeit an enhancement in locoregional-free survival was observed. We aimed to evaluate the relative influence of locoregional recurrence (LR) and distant metastasis (DM) on OS for patients with NSCLC after surgery.
Methods: This was a secondary analysis of PORT-C RCT.

Background: With clinical trials on the use of different modern precise radiotherapy techniques in the setting of postoperative radiotherapy (PORT) in N2 non-small cell lung cancer (NSCLC) accumulating, an updated meta-analysis was performed.
Methods: A literature search identified studies that investigated PORT versus non-PORT in N2 NSCLC patients. Overall survival (OS) and locoregional recurrence (LR) were employed.

Background: The exact role of postoperative radiotherapy (PORT) in patients with Masaoka-Koga stage IIB thymoma following extirpative surgery (defined as radical surgery or total thymectomy) is still under debate. This study was designed to evaluate the effect of PORT on survival in patients with stage IIB thymoma following extirpative surgery in a population-based registry.
Methods: Patients with Masaoka-Koga stage IIB thymoma who underwent extirpative surgery between 2000 and 2019 were identified from the Surveillance, Epidemiology, and End Results (SEER) database.
Postoperative Radiotherapy in Curatively Resected Esophageal Squamous Cell Carcinoma With Occult Recurrent Laryngeal Nerve Lymph Node Metastasis.

Department of Radiation Oncology, Fudan University Shanghai Cancer Center, Shanghai, People's Republic of China.
Objectives: Surgery is the mainstream treatment for early-stage esophageal squamous cell carcinoma (ESCC) and occult recurrent laryngeal nerve lymph node metastasis (RLNM) is not uncommon among those with R0 resection. The clinical value of postoperative radiotherapy (PORT) in patients with RLNM only is still controversial.
Methods: Consecutive patients with early-stage ESCC treated with R0 resection and pathologically confirmed RLNM only from June 2012 to July 2022 were retrospectively reviewed.

Background: Evidence suggests that radiotherapy is a potent immunomodulator in non-small cell lung cancer (NSCLC). Conversely, it has rarely been demonstrated if immune infiltration can influence radiotherapy efficacy. Herein, we explored the effect of tumor-infiltrating lymphocytes (TILs) on the response to postoperative radiotherapy (PORT) in completely resected stage III-pN2 NSCLC.
