RESUMEN
Objective:To determine the predictive value of preoperative monocyte-to-lymphocyte ratio(MLR) for prognosis in elderly patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy(RNU).Methods:A retrospective study was performed on 168 elderly patients who underwent RNU in Beijing Hospital between March 2004 to February 2019.Males accounted for 44.6% (75 patients) and females 55.4%(93 patients) of the patients. Median age at the time of surgery was 73(69-78) years, and 110 (65.5%) patients suffered from hydronephrosis. There were 147 cases(87.5%)with single tumor, and 21 cases(12.5%)with multiple tumors, including 75(46.6%) cases in renal pelvis or pelvi-ureteric junction, and 93(53.4%)cases in ureter. Open RNU was performed in 106(63.1%) patients, and laparoscopic method in 62(32.9%) patients. The optimal cutoff value of MLR was set as 0.22 by using the median.χ 2 test, which was used to detect the association between MLR(≤0.22 vs.>0.22) and clinicopathological variables. Survival analyses were performed using the Kaplan-Meier method and were compared using the log-rank test. Additional subgroup analyses(low grade vs. high grade) were performed according to pathological grade. Univariate and multivariate analysis by Cox’s proportional hazards model was used to determine the significance of MLR in respect to OS and PFS. Results:The follow-up period ranged from 19.2 to 86.9 months (median 51.9 months). Next, the cohort was divided into 2 groups , including 77 patients with low MLR(≤0.22) and 91 patients with high MLR(>0.22). High MLR was significantly more frequent in male patients(31.2% vs.56.0%), as well as those undergoing laparoscopic surgery (54.5% vs.70.3%)(All P<0.05). Based on a Cox univariate proportional hazards analysis, male gender( HR=1.793, 95% CI 1.003-3.205, P=0.049), presence of lymph node metastasis( HR=6.809, 95% CI 2.124-17.454, P=0.001) and high MLR( HR=2.287, 95% CI 1.259-4.154, P=0.007)were associated with poor OS. Male gender( HR=1.758, 95% CI 1.066-2.902, P=0.027), presence of lymph node metastasis( HR=6.524, 95% CI 2.542-16.748, P<0.001), lymphovascular invasion(LVI) ( HR=2.348, 95% CI 1.139-4.838, P=0.021), high MLR( HR=2.801, 95% CI 1.657-4.735, P<0.001)and PLR( HR=1.663, 95% CI 1.003-2.757, P=0.049) were significantly associated with subsequent PFS. By multivariate analysis, tumor site( HR=2.050, 95% CI 1.079-3.892, P=0.028), lymph node metastasis ( HR=6.641, 95% CI 1.852-23.811, P=0.004) and MLR( HR=2.089, 95% CI 1.062-4.113, P=0.033) were the independent risk factors for OS in elderly patients with UTUC. Tumor side( HR=2.024, 95% CI 1.033-3.965, P=0.040), multifocality ( HR=2.992, 95% CI 1.161-7.713, P=0.023), lymph node metastasis ( HR=6.454, 95% CI 2.026-20.564, P=0.002) and MLR( HR=2.866, 95% CI 1.554-5.284, P=0.001) were associated with PFS.The multivariate analysis of the significant risk factors established a postoperative risk stratification model for OS and PFS. The results showed significant differences among the 3 subgroups of patients with low(0 risk factor), intermediate(1 risk factor), or high risk(2-3 risk factors)(All P<0.05). Conclusion:MLR was an independent risk factor for OS and PFS in elderly patients with UTUC and patients with elevated MLR have worsen prognosis.

Objective To analyze effects of androgen deprivation therapy on lipid metabolism and nutritional status in patients with prostate cancer.Methods The clinical data of 255 elderly patients (≥ 65 years old) with prostate cancer who received endocrine therapy and complete follow-up data from January 2010 to December 2018 were analyzed retrospectively.The median age of the 255 patients was 76 years (65-92).The average PSA of patients was (58.15 ± 9.62) ng/ml,where 101 patients had PSA ＜ 10 ng/ml,62 patients had PSA 10-20 ng/ml,and 92 patients had PSA ＞ 20 ng/ml.All patients were diagnosed pathologically by prostate biopsy.As for Gleason score,Gleason score≤6,Gleason score =7 and Gleason score ≥ 8 had 62,103 and 90 patients,respectively.Endocrine therapy included maximum androgen blockade (197 cases) and drug castration (58 cases),and continued for at least 1 year.Among them,123 cases had complete blood lipid index data,and the subgroup analysis was based on the age of 80 years old,including 98 cases aged 65 to 80 years old and 25 cases over 80 years old.A total of 186 cases had complete data of total protein and albumin,of which 147 cases were 65 years old and 80 years old and 39 cases were more than 80 years old.Before treatment,cholesterol was (4.08 ±0.87) mmoL/L,including (4.14 ±0.86) mmol/L in the 65-80 years old group,(3.82 ± 0.88) mmol/L in ＞ 80 years old group;triglyceride was (1.23 ± 0.56) mmol/L,65-80 age group was (1.26 ± 0.56) mmol/L and ＞ 80 years old group was (1.11 ± 0.57) mmol/L;High density lipoprotein cholesterol was(1.09 ± 0.24)mmol/L,65-80 age group was (1.10 ±0.25) mmol/L and ＞ 80 years group was (1.04 ± 0.21) mmol/L.Low density lipoprotein cholesterol was (2.50 ± 0.78) mmol/L,65 ～ 80 age group was (2.55 ± 0.77) mmol/L and (2.34 ± 0.83) mmol/L in ＞80 years old group.The total protein before endocrine therapy was (63.81 ± 5.93) g/L,including (63.95 ± 5.79) g/L in the 65-80 years old group,(63.30 ± 6.49) g/L in ＞ 80 years old group.In terms of pre-treatment albumin (39.68 ± 3.50) g/L,including (39.82 ± 3.60) g/L in the 65-80 years old group and (39.21 ± 3.12) g/L in ＞ 80 years old group.The differences of various indexes before and after treatment were analyzed.Results The results of blood lipid data analysis of 123 cases showed that,there were increased significant differences(P ＜ 0.01) in cholesterol (4.80 ± 1.82)mmol/L,triglyceride (1.59 ± 1.17) mmol/L,high density lipoprotein cholesterol (1.21 ± 0.25) mmol/L and low density lipoprotein cholesterol (3.07 ± 1.53) mmol/L after endocrine therapy compared with baseline.In the subgroup analysis,the levels of cholesterol,triglyceride,high density lipoprotein cholesterol and low density lipoprotein cholesterol in 65-80-year-old group after treatment were (4.92 ± 1.95) mmol/L,(1.64 ± 1.25) mmol/L,(1.20 ± 0.25) mmol/L,and (3.15 ± 1.66) mmol/L,respectively,which were significantly higher than those before treatment (P ＜0.01).In the group over 80 years old,the blood lipid index after treatment was higher than that before treatment,including cholesterol (4.35 ± 1.08) mmol/L,triglyceride (1.39 ± 0.73) mmoL/L,high density lipoprotein cholesterol (1.27 ± 0.26) mmol/L and low density lipoprotein cholesterol (2.76 ± 0.93) mmol/L.The levels of cholesterol,triglyceride and high density lipoprotein cholesterol were significantly higher than those before treatment (P ＜ 0.05),but there was no significant difference in low density lipoprotein cholesterol between before and after treatment (P ＞ 0.05).The results of data analysis of 186 cases of total protein and albumin showed that,the total protein after treatment was (62.81 ±7.34) g/L,which was not significantly different from that before treatment (P ＞ 0.05).The total protein in 65-80 years old group after treatment was (62.36 ± 7.36) g/L,which decrease and have statistical significantly different from that before treatment (P ＜ 0.05);The total protein in ＞ 80 years old group after treatment was (64.49 ± 7.12) g/L,it was higher than that before treatment,but the difference was not statistically significant (P ＞ 0.05).The level of albumin after endocrine therapy was (38.34 ± 4.48) g/L,which was significantly different from that before treatment (P ＜ 0.01).The levels of albumin in 65-85 years old group and ＞ 80 years old group after treatment were (38.32 ± 4.54) g/L and (38.44 ± 4.30) g/L respectively,but only in the group of 65 to 80 years old,there were significant differences compared with those before treatment (P ＜ 0.05).Conclusion Endocrine therapy can not only significantly increase total cholesterol,triglyceride,low density lipoprotein cholesterol and high density lipoprotein cholesterol in elderly patients with prostate cancer,but also significantly reduce albumin after treatment.
RESUMEN
Objective:To investigate the effect of maximal androgen blockade(MAB)therapy on serum calcium, phosphorus and other metabolic indices in elderly patients with prostate cancer.Methods:Clinicopathological data of prostate cancer patients treated with MAB in our department from January 2010 to December 2018 were retrospectively analyzed.All patients underwent prostate biopsy for definitive diagnosis.Detailed data on patient's age, body mass index(BMI), previous medical history, treatment plan and peripheral blood indicators before and after endocrine treatment, such as blood calcium, phosphorus, hemoglobin, fasting blood glucose, triglycerides and cholesterol, were collected.Results:Patients had a mean age of(75.5±5.8)years and a mean BMI of(24.6±3.2)kg/m 2.Blood calcium levels exhibited a downward trend after MAB treatment compared pre-treatment[(2.12±0.44)mmol/L vs.(2.17±0.31)mmol/L, t=0.82, P=0.42], but had no significant difference.Serum phosphorus concentrations were higher and the calcium-phosphorus ratio was lower after MAB treatment than before treatment[(1.02±0.26)mmol/L vs.(1.17±0.34)mmol/L, 2.10±0.28 vs.1.88±0.60, t=-4.12 and 3.56, P<0.01]. After MAB treatment, blood fasting glucose[(6.50±1.55)mmol/L vs.(5.34±1.04)mmol/L, t=-7.82, P<0.01], triglycerides[(1.66±1.32)mmol/L vs.(1.22±0.59)mmol/L, t=-3.38, P<0.01]and cholesterol[(4.70±1.08)mmol/L vs.(4.16±0.90)mmol/L, t=-4.72, P<0.01]were elevated, while hemoglobin concentrations[(122.11±20.43)g/L vs.(130.78±23.98)g/L, t=3.98, P<0.01]were decreased compared with pre-treatment levels. Conclusions:MAB therapy can cause varying degrees of metabolic abnormalities in calcium and phosphorus metabolism, hemoglobin concentrations, blood glucose and lipid levels in elderly prostate cancer patients.The above indicators should be closely monitored during treatment, and treatment-related complications should be proactively prevented.
