Neuroendocrine tumors are aggressive and rare tumors which can occur almost everywhere in the body. The annual incidence of neuroendocrine tumors is 2.5-5 per 100000. We report seven cases of gastrointestinal neuroendocrine tumors which were diagnosed and treated at our hospital from the time period of 2016-2018 knowing that the total number of our hospital tumor board cases registry during the same period was 444 cases.

Melanoma is an aggressive tumor that is challenging to treat. Talimogene laherparepvec (T-VEC), the first oncolytic virus treatment approved by the US Food and Drug Administration to treat unresectable melanoma, was recently used in recurrent tumors after initial surgery. Our network meta-analysis aimed to compare T-VEC treatment of metastatic melanoma with treatment of granulocyte-macrophage colony-stimulating factor (GM-CSF) and control group.

The CNS tumor-embryonal tumors (CETs) have limited therapeutic options with high probability of adverse events associated with conventional treatment. Identification of somatostatin receptor expression and/or prostate-specific membrane antigen expression in CET patients by using PET/CT imaging may be helpful for deciding therapeutic approaches in these patients as theranostics.

A novel molecular classification for small cell lung cancer (SCLC) has been established utilizing the transcription factors achaete-scute homologue 1 (ASCL1), neurogenic differentiation factor 1 (NeuroD1), POU class 2 homeobox 3 (POU2F3), and yes-associated protein 1 (YAP1). This classification was predicated on the transcription factors. Conversely, there is a paucity of information regarding the distribution of these markers in other subtypes of pulmonary neuroendocrine tumors (PNET).

The COVID-19 pandemic affected the timely diagnosis and treatment of many cancers, including melanoma, the fifth most common cancer in the U.S. This study aimed to quantify the disruption and recovery of melanoma detection, treatment, survival, and mortality during the pandemic by analyzing data from the Surveillance, Epidemiology, and End Results (SEER) program from 2000 to 2021.

Methods: The phase II AVENEC study evaluated the effect of avelumab (AVE, 10 mg/kg IV Q2W) in 60 patients with well-differentiated high-grade neuroendocrine tumors (NET G3, N=22) or poorly differentiated neuroendocrine carcinomas (NEC, N=38) progressing after ≥ one prior chemotherapy (excluding Merkel cell and small-cell lung cancer).
