Objective: The prognosis of brain metastasis is very poor and the
survival period is very short if the patient is not treated. The determination
of prognostic factors is important in order to avoid invasive treatment
interventions or unnecessary treatment in the management of patients with brain
metastases. In this study, prognostic factors and the effect of hypertension on
survival in patients with brain metastasis were investigated.
Method: In this study, the data of 463 patients diagnosed with
brain metastasis, who were admitted to Cumhuriyet University Radiation Oncology
department between 2007 and 2018, were retrospectively analyzed.
Results: The median age was 59 (18-82) years. There were 170
(37%) patients with comorbidity and 23% of these patients had hypertension in
their medical history. With regard to primary cancer diagnoses, 271 (58%)
patients had lung cancer, 91 (20%) breast, 31 (6%) gastrointestinal, 21 (5%)
genitourinary, 13 (3%) gynecological, 11 (2%) unknown cancer and 25 (5%) had
other types of cancer. At the time of diagnosis, 217 patients (47%) were in a
metastatic stage. Median survival was 4 months (0-130 months); mean survival
was 9.74 + 0.6 months; 1-year survival was 27% and 2-year survival was 13%. In
univariate analysis, gender (p = .001), age (p < .001), hypertension (p =
.018), primary diagnosis (p < .001), RPA (p < .001), number of lesions (p
< .001), SRS (p < .001), metastatectomy (p < .001) and primary disease
status (p = .002) were statistically significant. Multivariate analysis showed
that hypertension (HR: 1.29, 95%; CI: 1.02-1.71; p = .027), age (HR: 1.39, 95%; CI: 1.08-1.77; p =
.008), primary diagnosis (HR: 1.63, 95%; CI: 1.20 -2.23; p = .002), RPA (HR:
2.05, 95%; CI: 1.35-3.09; p = .001), metastatectomy (HR: 0.63, 95%; CI:
0.46-0.86; p = .004) and SRS (HR: 0.53, 95%; CI: 0.38-0.72, p < .001) were
independent prognostic factors.
Conclusions:
In
this study, the presence of hypertension was as important in the prognosis of
the disease as primary diagnosis, age, metastatectomy and SRS.
