Introducción.- El tracto gastrointestinal es el sitio más comúnmente afectado por el linfoma no Hodgkin extraganglionar y cerca del 60% de todos los casos ocurren en el estómago. El linfoma gástrico primario (LGP) se define como la neoplasia linfoide que afecta únicamente al estómago; puede comprometer los ganglios linfáticos regionales, pero no los mediastinales o retroperitoneales. Palabras Claves: Linfoma Gástrico Primario (LGP), helicobacter pylori, gastrectomía, esofagogastroscopia, neoadyuvancia. |

Introduction: Gastrointestinal tract is the most commolyn affected extranodal non-Hodgkin lymphoma and about 60% of cases accur in the stomach. Primary gastric lymphoma (LGP) is defined as lymphoid neoplasia affecting stomach only and can involve the lymph nodes, but not mediatinal or retroperitoneum. Materials and Methds: Areview of 5 medical records of patients treated in the National Oncology Institute with Primary Gastric Lymphoma. Chemotherapy protocols, time course and response to standard treatment were analyzed, and so surgery as complementary o definitive treatment in patients who did not respond to initial treatment. Result: Four of five patients had Helicobacter pylori positive (blood) and received treatment. CT scan of three patients reported asymmetric wall thickening of stomach, the esophagus-gastroscopy revealed various gastric mucosal lesions (localized or diffuse). Pathology reported theree patients with HIGH GRADE NON-HODGKIN LYMPHOMA B CELL, MALT TYPE. Three received with 6 cyclesof neoadyuvant chemotherapy with a duration between 6 to 8 months, after which endoscopic controls revealde persistent disease at pathology study, reason why surgical treatment was indicated. TWO patients did nor reseive neoadjuvant treatment and were sent directly to surgery, one for active gastrointestinal bleeding tumor, and another 80-years old cardio patient who did not accept neoadyuvant treatment. The surgical treatment was total radical D-2 gastrectomy plus esophagus yeyuni anastromosis in Y of Roux. The follow up shows that the five patients are still alive with a good oncologyc evolution, in periodic controls, after four years the first one and eight months the last one after surgery. Only 1 patient developed anastomotic stenosis 1 month after surgery that resolved with endoscopic dilatations. Conclusions: It is a need to establish, identify and ratify the protocols of the ION (SOLCA ) for Primary gastric lymphoma treatment, reminding the importance of surgical treatment as alternative complementary o definitive treatment for patients who not respond to traditional chemo or radiotherapy. Key Words.- Primary gastric lymphoma, Helicobacter pylori, gastrectomy, esophagus-gastroscopy, neodyuvant. |
