- There is no generally accepted standard chemotherapy in treatment of advanced and recurrent endometrial carcinoma. Cisplatin and doxorubicin with or without cyclophosphamide are widely used. Response rates have improved with combination chemotherapy compared with single-agent therapy. A platinum analog seems to be an important part of the chemotherapy regimen. Since few patients are cured from their disease and since the duration of response is short, further improvement of this therapy is warranted. During the past years, the taxanes (paclitaxel) are being added to prior evaluated regimens and not only improved response rates are reported but also increased toxicity is observed. In a prospective, phase II, multicenter study, carboplatin (area under the curve = 5) and paclitaxel (175 mg/m(2)) were evaluated in treatment of primary advanced and recurrent endometrial carcinoma. In total, 66 patients were recruited during the years 2000-2004. Eighteen primary advanced tumors and 48 recurrences were treated. All histologic types and tumor grades were allowed. The median follow-up was 57 months (range 37-69 months). The overall response rate was 67% (95% CI 55-78). The complete response rate was 29% and the partial response rate 38%. Primary advanced and recurrent tumors as well as endometrioid and nonendometrioid tumors showed similar response rates. The median response duration was 14 months. The 1- and 3-year survival rates were 82% and 33%, respectively. The main toxicities were hematologic and neurologic (sensory neuropathy). The response rates were encouraging, superior to prior platinum-containing regimens, but response duration and the long-term survival rate were still short. The neurologic toxicity was frequent and was a substantial problem in this series of patients. Further research is highly needed to improve the treatment of advanced and recurrent endometrial cancer.

- The aim of the study was to acquire knowledge that can be used to refine radical hysterectomy to improve quality-of-life outcome. Data were collected in 1996-1997 by means of an anonymous postal questionnaire in a follow-up study of two cohorts (patients and population controls). We attempted to enroll all 332 patients with stage IB-IIA cervical cancer registered in 1991-1992 at the seven departments of gynecological oncology in Sweden and 489 population controls. Ninety three (37%) of the 256 women with a history of cervical cancer who answered the questionnaire (77%) were treated with surgery alone. Three-hundred fifty population controls answered the questionnaire (72%). Women treated with radical hysterectomy, as compared with controls, had an 8-fold increase in symptoms indicating lymphedema (25% reported distress due to lymphedema), a nearly 9-fold increase in difficult emptying of the bladder, and a 22-fold increase in the need to strain to initiate bladder evacuation. Ninety percent of the patients were not willing to trade off survival for freedom from symptoms. Avoiding to induce long-term lymphedema or bladder-emptying difficulties would probably improve quality of life after radical hysterectomy (to cure cervical cancer). Few women want to compromise survival to avoid long-term symptoms.

- Seventeen patients with endometrial stromal sarcoma (ESS) diagnosed between 1970 and 1996 were evaluated according to DNA ploidy, S-phase fraction (SPF), p53, and mdm-2 expression, as well as traditional clinical and pathologic prognostic factors, such as tumor stage, grade, and mitotic index. DNA flow cytometric analysis and immunohistochemical staining for p53 and mdm-2 were performed on paraffin-embedded archival tissue from the uterine tumors. Flow cytometric DNA histograms were obtained from 16 patients. The patients ranged in age from 41 to 78 years (median, 57 years). Seven (41%) patients were premenopausal. Thirteen low-grade ESS were DNA diploid and had a low SPF. Of these, two overexpressed p53, while only one was mdm-2 positive. Among the four high-grade ESS we found one (25%) DNA diploid tumor and three (75%) DNA aneuploid tumors. Two (50%) had an SPF greater than 10%, three (75%) were p53-positive, and two (50%) overexpressed mdm-2. During the observation period, nine (53%) patients (five with low-grade and four with high-grade tumors) died of disease. The 5-year survival rate for patients with low-grade ESS was 74%, while all four patients with high-grade ESS died of disease within 14 months of diagnosis. Using the log-rank test, we found a significant correlation between survival and tumor grade (P = 0.007), DNA ploidy (P = 0.026), SPF (P = 0.048), and FIGO surgical stage (P = 0.026). In conclusion, we found that tumor grade was a strong predictor of clinical outcome in ESS. In addition, a worse prognosis was found for those ESS patients with advanced disease, DNA aneuploidy, and a high SPF. There was no difference between the recurrent and nonrecurrent group of early stage (surgical stage I), low-grade ESS with regard to clinicopathological features, DNA ploidy, SPF, p53, and mdm-2 expression. All patients with high-grade ESS died of disease within 14 months of diagnosis. In contrast, only three of the 11 patients with early stage, low-grade ESS died of disease.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- The objective of this study was to assess the value of p53, bcl-2, and p21WAF1/CIP1 immunoreactivity as predictors of pelvic lymph node metastases (LNM), recurrences, and death due to the disease in early stage (FIGO I-II) cervical carcinomas. FIGO stage, type of histopathology, and tumor grade were also evaluated in this series of patients treated by radical hysterectomy (Wertheim-Meigs) between 1965 and 1990. A total of 172 patients were included. A tumor was regarded as positive when more than 30% of the neoplastic cells exhibited immunoreactivity. Positive immunostaining was found in 8.9% for p53, in 43.5% for bcl-2, and in 25.0% for p21WAF1/CIP1. None of them was able to predict LNM or clinical outcome. Presence of LNM, tumor recurrence, and death from disease were significantly associated with the FIGO stage (P = 0.014, P = 0.009, and P = 0.001, respectively). The 5-year cancer-specific survival rate was 91.6% and the overall survival rate was 90.5%. It was concluded that immunohistochemically detected p53, bcl-2, and p21WAF1/CIP1 appeared to be of no predictive value with regard to LNM, tumor recurrences, or long-term survival in early cervical carcinomas.
