Furthermore , this therapy could increase the dem and on radiation re sources .
There is no evidence on which to make a recommendation for patients with node-negative tumours that have not penetrated the muscularis propria .
For patients unable to undergo radiation , adjuvant chemotherapy alone may be of benefit , particularly for those with lymph-node metastases .
There is insufficient evidence from r and omized trials to recommend neoadjuvant chemotherapy , or neoadjuvant or adjuvant radiotherapy or immunotherapy , either alone or in combination , outside a clinical trial .
OBJECTIVE To make recommendations on the use of neoadjuvant or adjuvant therapy in addition to surgery in patients with resectable gastric cancer ( T1 - 4 , N1 - 2 , M0 ) .
OPTIONS Neoadjuvant or adjuvant treatments compared with " curative " surgery alone .
OUTCOMES Overall survival , disease-free survival , and adverse effects .
The radiation fields used can possibly damage the left kidney , result ing in hypertension and other renal problems .
ADJUVANT CHEMOTHERAPY IN OPERABLE GASTRIC CANCER: 5 Year Follow-up of First British Stomach Cancer Group Trial
411 patients were entered into a prospect i ve , r and omised controlled trial of adjuvant chemotherapy after gastrectomy for adenocarcinoma . After a follow-up of at least 5 1/2 years there has been no survival advantage for those receiving adjuvant 5-fluorouracil and mitomycin C with or without an induction course of 5-fluorouracil , vincristine , cyclophosphamide , and methotrexate compared with those undergoing surgery only . There have been 366  deaths , including 22 from treatment-related conditions . A multivariate analysis of prognostic factors demonstrated that stage of disease , nodal and resection margin involvement , and the presence of residual disease are significant determinants of survival . Weight loss before surgery had a significant independent influence on survival . The combination of preoperative symptoms and intraoperative findings may be used to select patients for radical or palliative procedures
