Early metabolic syndrome in testicular germ cell tumors : A prospective study from India.

Abstract

e17010 Background: Metabolic syndrome (MS) is a known complication in patients of testicular germ cell tumors . Early metabolic syndrome is not well-defined and literature on the same is scarce. Methods: This is a single institutional prospective cohort study of patients with testicular germ cell tumors from Jan’2020 to June 2021 with a minimum follow-up of 6 months after treatment completion. Patients were evaluated for MS as per NCEP ATP (National Cholesterol Education Program Adult Treatment Plan) III criteria and partial MS was defined if any one abnormal criteria was present. Clinicopathologic and treatment characteristics were correlated with development of MS. Results: Thirty-six (25 nonseminomatous tumor and 11 seminoma) were included with median age of 29 yrs (range: 18-44). Treatment protocol was - platinum based chemotherapy [BEP (n = 7), EP(n = 18),VIP(n = 4) ]in 81% (n = 29/36), single agent carboplatin in 8% (n = 3/36), and surveillance only in 11% (n = 4/36) patients. Incidence of complete metabolic syndrome noted in 42% (n = 15) and partial metabolic syndrome in 36% (n = 13) of patients after median follow-up of 13.2 months (range-6-22). Deranged parameters detected were - high serum triglyceride (≥150 mg/dl) in 64% (n = 23/36), low serum HDL cholesterol (< 40 mg/dl) in 53% (n = 19/36), high blood pressure (≥130/85 mm of Hg) in 47% (n = 17/36), high waist circumference (> 110 cm) in 6% (n = 2/36) and high fasting plasma glucose (≥5.6 mmol/L) in 22% (n = 8/36) of patients. Median weight gain was 5 Kg (range: 2-14). The median time to development of metabolic syndrome was 143 days (range: 90-461). Hypogonadism (testosterone < 433ng/dl.) showed positive correlation (degree of freedom = 0.3143) and C-reactive protein showed negative correlation (degree of freedom -0.3090) with MS, respectively. Conclusions: Majority of Testicular germ cell tumor patients (n = 28, 78%) had features of early MS, irrespective of treatment modalities. Patients with hypogonadism are more likely to develop early MS. Larger prospective studies are warranted to assess the incidence of early MS in patients with testicular germ cell tumors and to formulate appropriate health intervention to mitigate its significant long-term effects on mortality and morbidity.
