BACKGROUND, The intent to curatively treat patients with gastric carcinoma
is based on complete surgical resection of the primary turner and its lymph
atic drainage. Postoperative adjuvant chemotherapy has failed to show a sig
nificant prognostic advantage for these patients. Preoperative chemotherapy
, based on promising results in the treatment of patients with disease in p
rimarily unresectable stages, is still being evaluated for those with local
ly advanced gastric carcinoma. Most published studies still lack adequate s
taging methods, and long term results of this treatment modality are not kn
own at present.
METHODS. In a Phase II study, a series of 42 patients with locally advanced
gastric carcinoma (International Union Against Cancer Stages IIIA, IIIB, a
nd nr) initially were staged with endoscopy, with endoscopic ultrasound to
establish the clinical tumor classification, with computed tomography scans
to rule out tumor infiltration of adjacent organs and to detect distant me
tastases, and with surgical laparoscopy to exclude occult peritoneal carcin
omatosis. Three or four planned cycles of neoadjuvant chemotherapy with eto
poside, doxorubicin, and cisplatinum were given prior to total gastrectomy.
RESULTS. After a complete follow-up of at least 5 years, there was a median
survival of 19.1 months for all patients. Only patients who underwent a co
mplete surgical tumor resection appeared to have a survival benefit, with a
median survival of 28.4 months. A superior survival rate was seen in patie
nts who had a major clinical response to chemotherapy, with a median surviv
al of 45 months.
CONCLUSIONS. Phase III studies comparing results from patients who undergo
neoadjuvant chemotherapy followed by surgery with results from patients who
undergo surgery alone should stress the value of adequate pretherapeutic s
taging and must be accompanied by studies of potential methods for predicti
ng tumor response. (C) 2001 American Cancer Society.
