Abstract
Purpose
As per GLOBACON 2012, the incidence of cervical cancer is 22.9% with a mortality rate of 54.9% (http://globocan.iarc.fr, 2010). As the disease affects relatively younger population, high fatality rate impacts family and society in a disastrous way. Cervical carcinoma has a relatively poor prognosis due to advanced stage at presentation. We retrospectively analysed the treated cases of carcinoma cervix to know the impact of various prognostic factors on survival and patterns of failure in our hospital.
Methods
All cases treated from 2010 to 2015 (total 920 pts) who completed curative treatment in a tertiary care hospital were analysed to evaluate overall survival, disease-free survival, factors impacting survival, patterns of failure, factors affecting failure, mortality, and treatment-related toxicity. OS and DFS were calculated with Kaplan–Meier method, and log-rank test was used to identify the difference between groups. Failure factors were correlated with logistic regression, and toxicity was expressed in percentage.
Results
Univariate and multivariate analyses were performed. Pre treatment staging, lymphadenopathy, imaging used for diagnosis, hemoglobin levels extent of vagina involved and during treatment usage of concurrent chemotherapy, dose of radiation used, development of neutropenia and aftercompletion of treatment type of response had shown significant impact on DFS and OS. The presence of lymphadenopathy, increasing involvement of vagina, low pretreatment haemoglobin levels, and not receiving chemotherapy had increased risk of failure, while pretreatment evaluation with CT or MRI decreased the risk of failure. Para-aortic nodes (28%) were the commonest among distant failures. Acute bowel toxicity and radiation proctitis were commonly seen.
Conclusions
Presentation in locally advanced stage decreases survival; hence, detection in early stages by population-based screening programmes is needed. Pretreatment imaging with MRI/CT improves staging and thereby improves survival. There is no impact of 2D versus 3D CRT planning; hence, in high-case-load centres, 2D planning may be used. Follow-up at regular intervals with imaging may aid in earlier identification of failures with better salvage and improved survival.
