Adnexal masses in pregnancy.

With the widespread use of routine abdominal ultrasound examination during pregnancy, adnexal masses are observed with increasing frequency. Most patients are clinically asymptomatic at the time of presentation, and most of the adnexal masses detected during early pregnancy disappear during the first 16 weeks of pregnancy. Ovarian tumors are estimated to occur in about 1 in 1,000 pregnancies and of these 3% are malignant. Here we present an overview about frequency, diagnostic procedures and pathological characteristics of these ovarian tumors. Moreover, current modalities for treatment during pregnancy are summarized. Surgical treatment of the adnexal masses has to be performed with adequate staging and debulking equal to the treatment of non-pregnant women. However, whereas during organogenesis abortion has to be considered prior to chemotherapy, later in pregnancy surgical debulking as complete as possible, followed by taxol-platinum chemotherapy is indicated. If the fetus is not viable at the time of primary surgery, neoadjuvant chemotherapy and complementation of surgery after delivery of the baby should be performed. It should be stressed that chemotherapy for ovarian cancer applied during pregnancy appears to be safe. However, no studies have evaluated the long-term consequences for children exposed to intra-uterine chemotherapy. Aspiration of cysts should be avoided, as the correlation between the histological evaluation of an ovarian malignancy and the cytological evaluation of aspirates is poor. Moreover, spillage of malignant cysts is hazardous for the patient.

Age-specific differences in treatment and survival of patients with cervical cancer in the southeast of The Netherlands, 1986-1996.

Age at diagnosis has been proven to be an important determinant of the choice of initial treatment for several sites of cancer. Elderly patients are more likely to receive no treatment or less intensive treatment modalities. This study analysed the influence of age on treatment choice and survival in patients diagnosed with cervical cancer. This population-based study used data on 1176 new cases of invasive cervical cancer diagnosed in the period of 1986-1996 from three regional cancer registries in the Netherlands. All available information on treatment and survival (on 1 January 1998) was recorded. Relative survival rates were calculated according to the Hakulinen method. Relative risks (RR) for excess mortality due to the diagnosis of cervical cancer were calculated with a regression model for relative survival rates. Only 5% of the patients aged 70 years and older (n=224) were diagnosed with stage IA disease, compared with 11 and 30% of the patients aged 50-69 years and 49 years and younger, respectively. Almost 50% of the 70+ patients with stage IB-IIA were treated with radiotherapy as a single treatment modality, whereas 64% of the patients aged < or =49 years were treated with surgery alone. In all age groups, treatment for advanced stage disease (stage > or =IIB) was radiotherapy alone. No treatment was given to 10% of the patients aged 70 years and older, 5% of those aged 50-69 years and 1% of those aged 49 years and younger. Five-year relative survival was 69% (95% Confidence Interval (CI): 66-72%) and differed significantly (P=0.001) with age (70+ years: 49%; 50-69 years 58%; < or =49 years: 81%). Multivariate analyses on a subset of patients showed that age was not an independent prognostic factor, whereas stage and treatment modality were very important prognostic factors. Although elderly cancer patients were sometimes treated differently from younger patients, this was in accordance with the guidelines. Relative survival rates differed significantly by age. The multivariate analyses on the subset of patients also revealed that excess mortality increased with age. However, when adjustment was made for stage and treatment, this difference disappeared. The influence of treatment on survival is likely to be due to the selection of patients based on other characteristics, such as tumour volume, comorbidity and performance status.
