Management of gestational trophoblastic tumours: a five-year clinical experience.
OBJECTIVE
An analysis of a 5-year clinical experience in the management of gestational trophoblastic tumours in a tertiary care hospital.


METHODS
A prospective cohort follow-up study.


METHODS
The study was conducted at Hayatabad Medical Complex, Peshawar from 1998 to 2003.


METHODS
A total of 30 cases were managed and a detailed analysis of these patients was done. Of these 13 followed Hydatidiform Mole, 10 after abortion and 7 after a term pregnancy.


RESULTS
Out of 30 cases of gestational trophoblastic tumour, 63.3% were between 21 and 38 years of age. Ninety percent of the patients presented with vaginal bleeding, while life-threatening hemorrhage occurred in 23.3%of the cases.43.3% of the patients had hydatidiform mole as an antecedent pregnancy and 36.7% of the patients presented within four months of the antecedent pregnancy. Blood groups O and B were most frequently encountered i.e. in 40% and 33.3% of the cases. Metastatic disease was present in 46.6% of the cases, of which 8 were high risk and one was of medium risk group. Major sites of metastasis were lungs (33.3%) and vagina (30%). Serum BHCG of 40,000 miu / ml and above was present in 53.3% of the cases (P=0.016) and number of metastasis >8 were found in 16.7% cases (P=0.001). Prior chemotherapy was given in only 2 patients and both of them died due to resistance. Chemotherapy was given to 100% of patients; survival was 100% in low-risk group and 50% in high-risk group (P=0.004). Overall mortality was 20% i.e. 6 patients died of the disease. Major side effects of chemotherapy were stomatitis (66.6%), alopecia (56.6%), low hemoglobin (60%), weight loss and recurrent infection.


CONCLUSIONS
Late diagnosis, previously failed chemotherapy and high WHO prognostic scores are major risk factors affecting outcome in these patients. Hence every female in reproductive age group with unexplained bleeding per vaginum should be investigated with serum BHCG (Beta human chorionic gonadotrophin).
