baseline. Patients with co-morbidities had worse sexual life. Pre-menopausal women demonstrated profound fall as well as slower recovery in sexual scores at 6 months compared to post-menopausal women. On analyzing the disease related and dosimetric parameters, patients with vaginal extension had a significant decrease in orgasm and a decreasing trend for arousal compared to patients without vaginal involvement. The physical aspects of arousal and orgasm in sexual life were consistently impacted in individuals who had extensive growth involving beyond the cervix affecting the vagina and parametrium. Eight patients had Grade I vaginal stenosis at 3-month follow-up. At the 6-month follow-up, one patient had Grade 3, one had Grade II and 11 patients had Grade I vaginal stenosis. At 9-month follow up, one patient had Grade 3, two had Grade 2 and 11 patients had Grade 1 vaginal stenosis. The mean Recto vaginal dose of the study patients was 65.3Gy (SD:59-73Gy) and the percentage of women who experienced at least Grade 1 toxicity was 22%. A significant correlation between the recto vaginal doses and vaginal stenosis was observed at six months after treatment. Mean Total TRAK value of the patients was 1.19cGy/m. Higher vaginal TRAK values did not attribute to increase in vaginal stenosis.

Conclusion:

In our study population, the patients demonstrated sexual dysfunction in both psychological (sexual worry) and functional components (arousal, orgasm, vaginal narrowing/shortening). Hence, we recommend that women with cervical cancer should undergo sexual counselling both before treatment and during follow up. Improvement in treatment planning techniques should be incorporated to minimize the doses to the related OARS.
