Eighty-two of 307 consecutive staging lymphadenectomies had nodal metastases (Stage D1 prostate carcinoma). Seventy-seven of the 82 cases had at least a 5-year follow-up and 50 had at least a 10-year follow-up. Three of these 77 cases had Grade 1 (well-differentiated) metastases, 59 (77%) had Grade 2-3 (moderately differentiated) metastases, and 15 (19%) had Grade 4 (poorly differentiated) metastases (M. D. Anderson Hospital [MDAH] grading system). The patients with moderately differentiated metastases had 5-year and 10-year survival rates of 79% and 34%, respectively, whereas the patients with poorly differentiated metastases had 5-year and 10-year survival rates of 13% and 0%, respectively (P less than 0.0001). This study demonstrates a statistically significant difference between the prognosis of Stage D1 patients with moderately differentiated metastases and Stage D1 patients with poorly differentiated metastases. Consequently, the evaluation of the histologic appearance of Stage D1 metastases may be of clinical importance.

A 65-year-old patient presented with recurrent, locally advanced poorly differentiated thyroid cancer despite 2 neck surgeries, and with newly diagnosed brain and skull base metastases. He was treated with palliative stereotactic radiosurgery to the brain and skull base lesions. Thereafter, as no targetable genetic alteration was identified and antiangiogenic multikinase inhibitors were deemed at high risk of hemorrhagic complications, off-label systemic therapies were considered.

NUT carcinoma is a rare, aggressive malignancy characterized by chromosomal rearrangements involving the NUTM1 gene. We present the case of a 47-year-old male with a history of hypertension, diagnosed with NUT carcinoma originating in the ethmoid sinus and accompanied by extensive neck metastases. The patient underwent a left modified radical neck dissection and endoscopic nasal tumor excision, followed by concurrent chemoradiotherapy.

Delta-like protein (DLL3) is a novel therapeutic target. DLL3 expression in gastroenteropancreatic neuroendocrine tumors (GEP-NECs) is poorly understood, complicating the distinction between well-differentiated neuroendocrine tumors G3 (NET G3) and poorly differentiated NEC. DLL3 immunohistochemistry (IHC) was performed on 248 primary GEP-NECs, correlating with clinicopathological parameters, NE markers, PD-L1, Ki67 index, and prognosis.

Purpose Of Review: Neuroendocrine tumours (NET) are rare entities arising from hormone producing cells in the gastroentero-pancreatic (GEP) tract. Surgery is the most common treatment of GEP-NETs.
Recent Findings: Improvements in surgical techniques allow for more locally advanced and metastasised GEP-NETs to be resected.
