Mixed pancreatic ductal adenocarcinoma and well-differentiated neuroendocrine tumor: A case report.
World J Gastrointest Oncol

Department of Pathology, Cooper University Hospital, Camden, NJ 08103, United States.
Background: Pancreatic mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) are rare malignancies affecting the pancreas. The World Health Organization defines MiNENs as neoplasms composed of morphologically recognizable neuroendocrine and non-neuroendocrine components, each constituting 30% or more of the tumor volume. Adenocarcinoma-neuroendocrine carcinoma is the most frequent MiNEN combination.

Article Synopsis
- * Further tests, including endoscopic ultrasound and histopathological analysis, revealed the mass was actually a grade 1 neuroendocrine tumor (NET), changing the diagnosis before surgery.
- * After surgery, the pathology showed a mixed tumor containing both NET (Grade 1 and Grade 3) and invasive PDAC, illustrating the complexity of accurately diagnosing mixed tumors preoperatively due to overlapping features.

Keijzers); and Department of Surgical Oncology, Medical Center Leeuwarden, Leeuwarden, the Netherlands (P.M.v.d.T.).
Article Synopsis
- This study aims to define criteria for treating colorectal liver metastases (CRLM) using a three-dimensional liver model created by an expert panel, allowing for better treatment predictions.
- Data from two multicenter trials involved 202 participants with small CRLM (≤3 cm) and explored treatment options like resection, thermal ablation, and irreversible electroporation (IRE).
- The findings indicate a clear distinction in treatment preferences based on tumor location, suggesting superficial tumors should be resected, while deeper tumors should be treated with ablation, effectively predicting treatment recommendations in 73.8% of cases.
Simultaneous Prostate and Bladder Cancer with Collision Lymph Node Metastasis: A Case Report and Literature Review.
Medicina (Kaunas)
September 2024
Urology Department, Iuliu Hatieganu University of Medicine and Pharmacy, 400487 Cluj-Napoca, Romania.
Synchronous prostatic adenocarcinoma found in patients with muscle-invasive bladder cancer (MIBC) that undergo radical cistoprostatectomy is not uncommon. Nonetheless, the occurrence of collision metastasis, where both prostate cancer and bladder cancer involve the same lymph node, is exceptionally uncommon, with few cases being reported in the literature. We present a case of a 65-year-old patient diagnosed with MIBC who underwent laparoscopic radical cistoprostatectomy with extended lymph node dissection and intracorporeal ileal conduit.

Department of Neurological Surgery, Wexner Medical Center at The Ohio State University, Doan Hall N 1049, 460 W 10th Ave., Columbus, OH, 43210, USA.
Purpose: This study investigates the rare occurrence of tumor-to-tumor metastasis in Pituitary Neuroendocrine Tumors (PitNETs), also known as pituitary adenomas, aiming to enhance understanding of its diagnostic and therapeutic challenges. We report two cases from our institution of tumor-to-tumor metastasis involving PitNETs, followed by a systematic literature review.
Methods: We conducted a comprehensive literature review using PubMed and Google Scholar databases.
