Abstract:
Objective:To discuss the clinical features and prognostic factors of adrenal metastases.Methods:The clinical data of 37 patients with adrenal metastases admitted to the First Affiliated Hospital of Guangxi Medical University from May 2015 to August 2022 were retrospectively analyzed. There were 30 males and 7 females. The median age was 54 (43, 62) years old, including 13 cases aged ≥60 years old and 24 cases aged < 60 years old. There were 22 cases of right metastasis, 12 cases of left metastasis and 3 cases of bilateral metastasis. The maximum diameter of metastatic carcinoma was <3 cm in 10 cases, 3-6 cm in 18 cases, and >6 cm in 9 cases. There were 20 cases of synchronous metastasis (diagnosed with adrenal metastasis at the same time as the primary tumor) and 17 cases of metachronous metastasis (found after the diagnosis of primary tumor). There were 20 cases of adrenal metastasis alone and 17 cases of adrenal metastasis combined with other distant metastasis. 16 cases underwent adrenalectomy, 15 cases underwent adrenalectomy combined with other organ resection, and 6 cases underwent ultrasound-guided needle biopsy. 18 patients were treated with surgery alone, and 19 patients were treated with combined treatment (surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapy, interventional therapy and seed implantation). There were 12 cases of hepatocellular carcinoma, 8 cases of renal clear cell carcinoma, 5 cases of lung adenocarcinoma, 2 cases of colon adenocarcinoma, 2 cases of neuroblastoma, 1 case of renal pelvis carcinoma, 1 case of gastric adenocarcinoma, 1 case of cholangiocarcinoma, 1 case of renal papillary cell carcinoma, 1 case of colon adenosquamous carcinoma, 1 case of thymic small cell carcinoma, 1 case of endometrial carcinoma, and 1 case of diffuse large B-cell lymphoma. The Kaplan-Meier method was used to draw the survival curve, the log-rank test was used to analyze the relationship between the clinical characteristics of patients and overall survival (OS) and progression-free survival (PFS), and the Cox proportional hazards regression model was used to analyze the factors affecting OS.Results:The median follow-up time of the 37 patients was 10 (4, 18.5) months.The overall survival rates at 6 months, 1 year and 2 years were 59.5% (22/37), 43.2% (16/37) and 32.4% (12/37), respectively. The 6-month, 1-year and 2-year overall survival rates of 18 patients who underwent surgery alone were 66.7% (12/18), 44.4% (8/18) and 27.8% (5/18), respectively. The 6 months, 1 year and 2 years overall survival rates of 19 patients with comprehensive treatment were 52.6% (10/19), 42.1% (8/19) and 36.8% (7/19), respectively. There was no significant difference in overall survival rate between the two groups ( P=0.773). Kaplan-Meier survival curve analysis showed that the side of metastatic cancer was a risk factor for OS ( P=0.012) and PFS ( P=0.013), and the time of diagnosis of metastatic cancer was a risk factor for OS ( P=0.021). Univariate Cox regression analysis showed that, time to diagnosis of metastases ( HR=2.5, 95% CI 1.1-5.4, P=0.021), side of metastases ( HR=3.6, 95% CI 1.5-8.5, P=0.004), pulmonary metastases ( HR=3.6, 95% CI 1.1-11.0, P=0.032) and adenocarcinoma of the primary tumor ( HR=3.2, 95% CI 1.2-8.8, P=0.025) were risk factors for OS. Multivariate Cox regression analysis showed that simultaneous presence of metastases ( HR=2.6, 95% CI 1.1-6.2, P=0.033) and metastases located on the left side ( HR=3.6, 95% CI 1.5-8.6, P=0.005) were independent risk factors for OS. Conclusions:Hepatocellular carcinoma is the most common pathological type of adrenal metastases in this study. Patients may benefit from combined therapy based on surgery. The time of diagnosis, side, tumor origin and pathological type of primary tumor are the prognostic factors of adrenal metastases. Simultaneous presence of metastases and left-sided metastases are independent risk factors for OS in patients with adrenal metastases.
