Introduction. Pregnancy-related cancer is defined as cancer diagnosed during pregnancy or in the first postpartum year. Cervical cancer affects approximately 1 in 1000 pregnant women and is the most common malignancy affecting pregnancy. We retrospectively analysed the clinical outcome and results of treatment in patients with pregnancy--related cervical cancer. Material and methods. We retrospectively analysed the medical records of nine patients with invasive cervical cancer diagnosed during pregnancy and the postpartum period who had been treated in the Regional Oncological Centre, Łódź, between 2011-2014. Results. Three patients with cervical cancer at stage I were diagnosed between the 14 th and 17 th week of pregnancy afterwards and underwent radical surgery. Two patients with cervical cancer at stage Ib who were diagnosed in the 19 th and 24 th week of gestation decided to continue pregnancy until the 30 th and 32 nd week; then a cesarean section combined with radical surgery was performed. In three patients with inoperative cervical cancer diagnosed between the 26 th and 28 th week of pregnancy, a cesarean section was performed at week 30-32. In one patient cervical cancer at stage IIb was diagnosed during the post-partum period. All patients were treated using intensity-modulated radiotherapy (IMRT) to a total dose of 44 Gy/2Gy, weekly cisplatin (40 mg/m 2 ) concurrent with radiotherapy and brachytherapy. No toxicity was observed. During follow-up, two patients with inoperable cervical cancer were diagnosed with a recurrence 2 and 10 months after treatment, respectively. Conclusions. The management of pregnancy-related cervical cancer is mainly determined by the week of the pregnancy and the stage of the disease at diagnosis, but also by the patient choice. The general condition and follow-up of newborns from pregnancies complicated by cervical cancer are similar to those of newborns arising from non--complicated pregnancies. Treatment toxicity is similar in cases with pregnancy-related cervical cancer and in non--pregnant women with cervical cancer. The major prognostic factor in pregnancy-related cervical cancer remains the stage of the disease at diagnosis. NOWOTWORY J Oncol 2016; 66, 5: 359-366
