The median age was 52 (27\u201381) years. There was a female predominance (70.7%). NEC was the most common subtype (84.4%) followed by MiNEN (12.9%) and NET (2.7%). The most common stage at presentation was metastatic (70.7%) followed by locally advanced (21.8%), and early disease (7.5%). The median follow\u2010up was 9.92 (1.77\u201376.06) months. Median OS was 6.14 (3.93\u20138.35) months. Median OS in patients who received multimodality treatment was 20.20 (17.99\u201322.41) months versus 4.00 (2.91\u20135.10) months in those who did not receive it.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>GB NENs are rare, but aggressive tumors with NEC being the most common type. Multimodality treatment yields favorable outcomes.
