Background  Carcinoma cervix is one of the commonest malignancies in females.  Locally advanced carcinoma cervix is managed with concurrent chemoradiation.  Brachytherapy is usually delivered by either HDR or LDR machines.  ABS(American Brachytherapy Society recommeneds maximum 7.5Gy/fr and min 4 fr)1  1 ref:Nag s etal Int J Radiat oncol Biol Phy 2000,48,201

 In high volume centers for adequate use of resources, their were studies assessing HDR ICRT with reduce fractionation schedules  Hama Y et al Radiology ;  6.8x 3f vs 9gy x2  Firuza patel,pankaj kumar et alBrachytherapyBrachytherapy  Volume 10, Issue 2, March–April 2011, Pages 147–153 Volume 10, Issue 2

Aims and Objectives  To compare two different fractionation schedules in high dose brachytherapy for carcinoma cervix with respect to locoregional control of the disease

methodology  Study setting :- Dept. of Radiotherapy Calicut medical college  Study design :- retrospective cohort  Study period : jan – 2011 jan

inclusion criteria  All patients with ca cervix, stage II & III who took treatment from our college  Performance status – 1 & 2  Age between – 35 – 65 years  Squamous cell carcinoma histology

Exclusion criteria  Performance status – 3 & 4  No proper follow up  Age > 65 years  Stage IV disease  Non concurrent EBRT given cases

Materials & methods  124 patients with carcinoma cervix with stage II & III were given concurrent chemo radiotherapy  cisplain 40 mg/m2 weekly  RT dose of 45Gy/23 #

 Patients are divided in 2 arms  7Gy given weekly in 3 sittings  9Gy given weekly in 2 sittings

 All patients are assessed clinically for residual disease after CCRT  All patients are followed up as per guidelines for one year for loco regional recurrence acute complications  Recurrences are confirmed with biopsy

toxicities  Bladder – grade I- 9Gy – 15% 7 Gy- 20%  None of the pts needed intervention for heamatologic toxicities  Bleeding PR one patient from both arms reported bleeding PR was managed conservatively

conclusion  In carcinoma cervix CCRT followed by HDR ICRT with 9Gy wkly in two fraction is equaly effective in local control as 7GYin three fractions in a follow up period of one year  These patients should be followed up for late toxicities

limitations  Not a prospective study  Only short term follow up
