Single-agent dactinomycin has activity in patients with low-risk GTD who develop MTX resistance and whose hCG is low. Simplifying the stratification of GTD into two classes (low- and high-risk) does not compromise overall outcome and may reduce the risk of second tumors.

This study has identified cases of stem villous hydrops, mesenchymal dysplasia or Beckwith-Wiedemann spectrum in pregnancies initially diagnosed as partial hydatidiform mole in the second half of pregnancy and has highlighted the need for detailed pathological examination and clinicopathological correlation in all such cases.

We have compared the clinical and histological features of 149 complete moles with 146 triploid partial moles and 107 diploid non-molar hydropic abortions initially registered as moles for human chorionic gonadotrophin (hCG) follow-up. Forty-one patients with complete moles, five with partial moles and one with hydropic abortion received chemotherapy for hCG elevations interpreted as persistent trophoblastic disease. Complete moles were aborted or were evacuated significantly earlier than partial moles (means of 12.1 and 15.4 weeks; P < 0.001) and hydropic abortions significantly earlier than complete moles (mean 10.7 weeks; P < 0.005). The means of the highest recorded hCG were higher in complete moles (184,056 i.v.) than in partial moles (66,259 i.v.) and hydropic abortion (7942 i.v.). When hCG became normal without chemotherapy, this occurred earlier in patients with hydropic abortion than in those with partial moles (means of 46.7 days and 62.8 days; P < 0.001) and earlier in partial moles than in complete moles (mean 78.3 days; P < 0.005). The incidence of partial moles was comparable throughout fertile years but rose to 1.9 times the average after 40 years. Complete moles were commoner between 14 and 25 years and after 35 years, reaching 4.8 times the average after 40 years. Hydropic abortions were rare before 25 years and increased with age to 12 times the average after 40 years. Stromal karyorrhexis and shape of villi, before they become hydropic, discriminate well between complete and partial mole. Hydrops increased and vascularity decreased with molar age and the presence of non-hydropic villi or vessels did not discriminate between partial mole and the younger complete moles evacuated nowadays.

Objective To ascertain the mode of presentation and treatment outcome for women with choriocarcinoma after a nonmolar pregnancy. Design Retrospective analysis of case records between 1985 and 1994. Setting A referral centre for trophoblastic disease. Subjects One hundred women with choriocarcinoma: 62 after a live birth, six after a live birth preceded by a molar pregnancy and 32 after a nonmolar abortion. Results Choriocarcinoma after nonmolar pregnancies represent 17% of the total gestational trophoblastic tumours requiring treatment. Vaginal bleeding was the commonest symptom in all groups, but symptoms from metastatic disease were important in the group presenting after a live birth. Metastatic disease was present in 31% of cases after live birth and 43% post‐abortion. The median interval between the antecedent pregnancy and choriocarcinoma was five and six months, respectively. High risk multi‐agent chemotherapy was required in 82% and 60% of cases, respectively. The mortality rate was significantly higher after a live birth than a nonmolar abortion (21%vs 6%). Conclusions Treatment of choriocarcinoma after a live birth is associated with an unacceptably high mortality rate. Vaginal bleeding is an important early symptom and a pregnancy test should be performed if it persists after usual medical treatment.

This study suggests that there is a slight increased risk of second tumors after sequential or combination chemotherapy for GTT. This has become apparent since the introduction of etoposide and longer follow-up.

Weight loss is a major manifestation of infection with the human immunodeficiency virus (HIV). Prospective analysis of weight change was performed in 30 male subjects with stage IV HIV infection over a period of 9-49 mo and weight change events (> 4 kg) related to contemporaneous clinical events. Two distinct patterns of weight loss were observed: episodes of acute severe weight loss and episodes of chronic unremitting progressive weight loss. Thirty-three acute episodes (median 9.1 kg in 1.7 mo) and 23 chronic episodes (13.2 kg in 9.5 mo) were identified. Twenty-seven of 33 (82%) acute weight-loss episodes were associated with nongastrointestinal opportunistic infections and 15 of 23 (65%) chronic episodes with gastrointestinal disease (P < 0.01). Weight loss was neither inevitable nor unremitting. Periods of weight stability (> 4 mo) occurred in 13 individuals (43%); 35 episodes of weight gain were identified, mostly related to recovery from opportunistic infection. These findings have important implications for our understanding of the natural history of weight loss in HIV infection.
