Background:
The prognosis of patients with brain metastases from gastroesophageal (GE) cancers remains unclear despite recent advances in systemic therapies. The authors present a large single-institution experience in the use of stereotactic radiosurgery (SRS).
Methods:
A retrospective review of 71 GE cancer patients (64 male, 90.14%) who underwent Gamma Knife SRS was conducted. Overall, 243 brain metastases were treated and the median number of metastases per patient was 2 (range:1-21). The median age at SRS was 66 years (range: 26-85) and the median treatment day KPS was 80 (range: 50-100). The median cumulative tumor volume was 6.7 cc (range: 0.27-104.76) and the median single-session margin dose was 18 Gy (range: 12-20).
Results:
The median overall survival after SRS was 7 months (range: 1-64). At last follow up, 54 (76.06%) patients were deceased, 8 of whom (14.81%) expired secondary to their intracranial metastases. Four patients (5.63%) experienced local tumor progression at a median time of 8 months (range: 2-13) after SRS. Ten patients (14%) experienced new remote tumor development at a median time of 4 months (range: 0-14) after SRS. Whole-brain radiation therapy (2 patients, 20%) and repeat SRS (8 patients, 80%) were used for newly developed tumors. The incidence of transient adverse radiation effects was 8.45%.
Conclusions:
In this study, the 12-month local tumor control rate was 90%. Incidences of adverse radiation effect rates were rare. The median overall survival of 7 months indicates the poor prognosis of patients with brain spread of their GE cancer.
