Aim: Gastric Cancer (GC) is a poor prognosis neoplasm and it is often diagnosed at advanced stage. Neoadjuvant Chemotherapy (NAC) may increase the possibility of complete surgical resection and improve Overall Survival (OS).
Patients and methods: Since November 2006, six patients with gastric adenocarcinoma, diagnosed by endoscopy, endoscopic ultrasonography and total body 18FDG-PET-CT, were enrolled in a program of peri-operative chemotherapy, according to the following inclusion criteria: cT2N+M0 or cT3-4NxM0, age < 75 years, Karnofsky Performance Status > 60%, absence of hepatic, renal and bone marrow failures. The patients undergo three cycles of pre-operative and post-operative chemotherapy based on Epirubicine, Cisplatin, and 5-Fluorouracil (ECF) as MAGIC Trial proposed. Fifteen days after the end of pre-operative chemotherapy the patient undergoes endoscopic ultrasonography and total body 18FDG-PET-CT to evaluate the tumor response to treatment, and then he is addressed to surgery. Thirty days after surgery he starts the post-operative chemotherapy.
Results: All patients completed the pre-operative chemotherapy. Five patients underwent D2 subtotal gastrectomy and only one patient D1 total gastrectomy. No peri- and post-operative mortality and morbidity were observed. One month after surgery all patients started chemotherapy. During post-operative chemotherapy two patients developed subclavian vein thrombosis, one patient developed renal failure.
Conclusions: Although surgical resection remains the key component in the treatment of GC, it is clear that improved outcome will depend on a multidisciplinary treatment. NAC is associated with appreciable toxicity and it may improve the OS, allowing the downstaging of the primary tumor and increasing its resecability, as shown by MAGIC trial.
