Purpose or Objective
A
significant portion of Carcinoma Cervix cases present in advanced stage. For these
palliative radiotherapy is a viable alternative. Aim of palliation is mostly to
provide symptomatic relief. In a small subset of patients’ good response warrants
further attempt at treatment with curative intent.
Material and Methods
Retrospective
analysis of 36 patients who received 30Gy/10# followed by EBRT (External Beam
Radiotherapy)/Brachy boost from January 2012 to December 2016 was done. These
patients had a relatively early age of presentation had preserved physical
function and had good performance status. They received 30Gy/10# over 2weeks
EBRT (Phase1) by conventional technique following which they were either given
a EBRT boost of 20Gy/10# or Brachytherapy 7.5GyX2# (Phase 2). At the end of
Phase 1 a subjective as well as an objective analysis was done. A CECT was done
3 months following completion of Phase 2.
Results
The
median age presentation of the cohort is 46 years (IQR 39-56). Most common
presenting symptom was vaginal bleeding in 29 (80.5%) patients followed by
pelvic pain 19(52.7%). Following phase 1; greater than 50% objective response
(as measured on CECT) was observed in 26 (72.2%) patients, remaining patients
had static disease. At completion of treatment (Phase 2) 19 (52.7%) patients
had complete radiological response whilst remainder had biopsy proven residual disease.
We present an analysis of these 19 patients. The median DFS was 3.2 years. Most
common site of failure was paraaortic nodes 7 (36.8%) followed by local relapse
4 (21%), one patient presented with lung metastasis, 4 patients have lost to
follow up and 3 (15%) patients stay symptomatic as of now. On univariate
analysis size of tumour greater than 6 cm was found to be significant (p=0.04).
On multivariate analysis size of tumour and duration of symptoms were found to
be significant.
Conclusion
A
small subject of carefully selected patients despite their advanced disease
shows good response to palliative hypo-fractionated radiotherapy. In these further
radiation by means of external beam radiotherapy or brachytherapy can be
contemplated with satisfactory results.
