First-line treatments
Exercise prescription and weight management
Treatment options should be discussed with a qualified healthcare provider.
Surgical Tumor Resection with Lymphadenectomy
More extensive surgical intervention including tumor removal with regional lymph node dissection, recommended for gastric NET G2 tumors with higher metastatic potential. May involve partial or total gastrectomy depending on tumor characteristics.
Additional treatment options
Peptide Receptor Radionuclide Therapy
Targeted radioligand therapy using radiolabeled somatostatin analogs for advanced or metastatic G2 tumors expressing somatostatin receptors. This precision therapy delivers cytotoxic radiation directly to tumor cells.
medicationTargeted Molecular Therapy
Everolimus or other mTOR inhibitors for advanced gastric neuroendocrine tumors progressing despite standard therapy. These agents interfere with tumor cell proliferation and angiogenesis pathways.
medicationMultimodal Tumor Monitoring
Integrated surveillance using CT, MRI, and functional imaging modalities to comprehensively assess tumor burden, treatment response, and detect metastatic progression. Coordinated imaging schedule essential for accurate disease staging.
monitoringPsycho-Oncological Support Services
Specialized psychological intervention addressing cancer-related anxiety, depression, and coping challenges specific to neuroendocrine tumor diagnosis. Includes individual therapy, support groups, and stress management techniques.
