Treatment Outcome of Cervical Cancer Patients in the Elderly Population Aged 80 Years and Above: A Single Institution Study

Abstract

Introduction: Age-related deficits such as malnutrition, functional reliance, and cognitive decline also occur in older women, as they are typically weaker and have many co-morbid conditions like diabetes or cardiac illness. These prognostic factors might predict overall survival and progression-free survival. Aim: To analyse the management outcomes of elderly patients with cervical carcinoma treated with radiotherapy and brachytherapy. Materials and Methods: A retrospective observational study was conducted in the Department of Radiation Oncology at Himalayan Institute of Medical Sciences, Dehradun, Uttarakhand, India. Medical records were collected from 876 patients with cervical cancer who had been treated with radiotherapy or combined radiotherapy and chemotherapy from January 2009 to December 2021. A total of 876 patients presented with cervical cancer in the Outpatient Department (OPD), and 20 patients meeting the inclusion criteria were selected. Patients diagnosed with cervical cancer, Federation International Federation of Gynaecology and Obstetrics (FIGO) stage IB to IVA, aged equal to or greater than 80 years old, and Eastern Cooperative Oncology Group (ECOG) performance status I to III were considered for inclusion. Categorical variables were expressed as counts and percentages. The following clinicopathological characteristics of the study population were examined: FIGO staging, including stage IB to stage IVA, histopathological features of adenocarcinoma, squamous carcinoma, or adenosquamous carcinoma, doses of radiotherapy and brachytherapy, overall survival, disease-free survival, and the patient’s current status (alive or dead) was determined. If death occurred, the cause of death was determined. The Kaplan-Meier approach was used to analyse overall survival and disease-free survival in the study population using XLSTAT statistical software. Results: The study population was age standardised, with 18 patients (90%) falling between the ages of 80 and 85, and 2 patients (10%) falling between the ages of 86 and 90. A total of 12 patients (60%) belonged to ECOG PS II. A total of 19 (95%) patients had histologically confirmed squamous cell carcinoma. 75% of the population was in a locally advanced stage (stage III-IVA). The overall survival (in months) was 65.58 months, which was statistically significant (p<0.0083). Similarly, the average disease-free interval was 38.73 months, which was also significant (p<0.0062). Conclusion: According to the findings of the study, age may not be an independent risk factor for determining the outcome of cervical cancer patients in the Indian scenario. Even though elderly females may present with multiple co-morbidities, the standard treatment protocol must be radical.
