- A management program for FIGO stage I-II nonserous, nonclear-cell adenocarcinomas was evaluated. Histopathology and DNA ploidy were used to estimate postoperatively the risk of progression or death of disease and to tailor treatment. The patient material was a population-based consecutive cohort of all women with endometrial cancer in the Southern Swedish Health Care Region diagnosed between June 1993 and June 1996 (n = 553). Of these, 335 were eligible for the management program. Patients estimated to be at low risk were treated by surgery only, while high-risk patients also received vaginal brachytherapy. A large low-risk group consisting of 84% (n = 283) of the patients with an estimated disease-specific 5-year survival of 96% (95% CI = 93-98%) was identified. The high-risk group (n = 52, 16%) showed a worse outcome with an 80% 5-year disease-specific survival (95% CI = 65-89%). The difference in survival between the groups was highly significant (P < 0.0001). Half of the progressions were distant in the high-risk group. Although there is a clear indication for adjuvant therapy for this group, locoregional radiotherapy could be expected to fail in cases with distant progression. Thus, effective systemic treatments need to be developed. Low-risk patients, constituting the majority (84%) of the patients, can be safely treated by surgery only.

- The present study was designed to analyze the relationship of human papillomavirus (HPV)-DNA, microvessel density, and their impact on clinical outcome in early cervical carcinoma. HPV-DNA was evaluated in 171 cases of cervical carcinoma treated from 1965 to 1990. In 110 cases, the analyses could be performed. A polymerase chain reaction technique was used on paraffin-embedded specimens obtained before the start of therapy. HPV-DNA of any type was detected in 78% (86/110) of all evaluable tumors. HPV16 was the predominant type and was detected in 56% (62/110), HPV18 in 8% (9/110), and HPV35 in 21% (23/110). Patients with tumors containing HPV16 or HPV18 were significantly (P = 0.011) younger than patients with tumors not containing either of these two subtypes. Vascular space invasion and lymph node metastases were observed more frequently in tumors expressing HPV16 and HPV18 (P = 0.002, P = 0.047) than in tumors negative for these HPV strains. Tumors containing HPV16 and HPV18 were significantly (P = 0.012) larger and more frequently (P = 0.005) associated with higher FIGO stages. The cancer-specific survival rate was lower for patients with HPV16- and HPV18-positive tumors, but the difference was not statistically significant. The microvessel density was a non-significant prognostic factor. The overall 5-year survival rate of the complete series was 91%. It was concluded that HPV-DNA was a prognostic factor in early-stage cervical cancer and was associated with the age of the patient, vascular space invasion, lymph node metastases, tumor size, and FIGO stage.

- At least one of ten patients with ovarian cancer is estimated to develop their tumor because of heredity with the breast and ovarian cancer syndrome due to mutations in the BRCA1 and BRCA2 genes and hereditary nonpolyposis colorectal cancer (HNPCC) being the major genetic causes. Cancer at young age is a hallmark of heredity, and ovarian cancers associated with HNPCC have been demonstrated to develop at a particularly early age. We used the Swedish Cancer Registry to identify a population-based series of 98 invasive epithelial ovarian cancers that developed before 40 years. Mucinous and endometrioid cancers were overrepresented and were diagnosed in 27% and 16% of the tumors, respectively. Immunostaining using antibodies against MLH1, PMS2, MSH2, and MSH6 was used to assess the mismatch-repair status and revealed loss of expression of MLH1/PMS2 in two cases, loss of MSH2/MSH6 in one case, and loss of MSH6 only in three tumors. A microsatellite instability–high phenotype was verified in five of six tumors. Based on the identified mutations and family history of cancer, several of these individuals are likely to be affected by HNPCC. We conclude that although the causes of the vast majority of epithelial ovarian cancer at young age are unknown, HNPCC should be considered because of the high risk of metachronous colorectal cancer in the individual and the possibility of preventing additional cancers in the family through control programs.
