Second lower genital tract squamous cell carcinoma following cervical cancer. A clinical study of 46 patients.
BACKGROUND
Patients after treatment for cervical cancer have increased risk of developing second squamous cell malignancy of the lower genital tract.


METHODS
A retrospective study of 46 patients with second lower genital tract epidermoid cancers following previous treatment for invasive cervical carcinoma.


RESULTS
Patient age at diagnosis of cervical cancer was 27 to 68 years (median 44 years) and at diagnosis of the second malignancy - 43 to 72 years (median 63 years). There were four cases (9%) of synchronous cancers. Time span between metachronous malignancies ranged from 66 to 406 months (median 206 months). In 32 cases (70%) second lesion was located in the vagina and in 14 (30%) - in the vulva. Out of 35 previously irradiated patients, in 24 (69%) second tumor was located within the high dose volume and in 11 (31%) - outside it. Treatment of second cancer consisted of surgery in 12 patients (26%), radiotherapy in 23 (50%), combined surgery and radiotherapy--in five (11%), chemotherapy in four (9%) and surgery plus chemotherapy - in one case. Median survival was 52 months and five-year survival from the diagnosis of second malignancy - 47.5%. No prognostic factors for survival were identified.


CONCLUSIONS
Treatment outcome in patients with second lower genital tract carcinoma is unsatisfactory due to poor feasibility of another definite treatment after previous radical surgery and/or radiotherapy.
