Human papillomavirus DNA in locally recurrent cervical cancer.

Ten vaginal and central recurrences of cervical carcinoma were analyzed by Southern blot hybridization under nonstringent and stringent conditions for the presence of human papillomavirus (HPV) type 11, 16, 18, 31, and 35 DNA. Cases judged HPV-negative by this assay were tested with the polymerase chain reaction (PCR) for HPV 16 and 18. All 10 recurrences were HPV-positive. Seven tumors contained HPV 16, one contained HPV 18, one contained HPV 16 and 18, and one contained HPV-related sequences. In three cases, where the corresponding primary tumor could be studied, the identical HPV type was contained. The consistent presence of HPV DNA in local recurrences of invasive cervical carcinoma argues in favor of a role of these viruses also in the maintenance and reappearance of malignancy.

[Effect of pregnancy on the incidence and course of malignant diseases]. / Einfluss einer Schwangerschaft auf Inzidenz und Verlauf von Malignomerkrankungen.

Fortunately, coincidence of pregnancy associated with malignant neoplasm is rare. As reported in the literature, incidence is 1.5-10: 10,000 pregnancies. The study presented reports data on the incidence and outcome of 16-35 years old female patients suffering from malignant neoplasms. Patients, who were treated in Freiburg 1980-1989, were considered for evaluation. We analysed the impact of pregnancy on the outcome of these patients by stratifying patients for the time of diagnosis (before, during, or after a pregnancy). 247 patients were included. 118 patients developed a neoplasia after a successful pregnancy. In 24 patients, neoplasia was diagnosed during pregnancy, and 28 patients became pregnant after diagnosis and therapy for a malignancy. Further 77 patients without pregnancy, but in whom neoplasia diagnosed at the age of 16-35 years were included. Cancer of the cervix uteri, breast cancer, ovarian cancer, and malignant lymphomas were the most frequent neoplasias diagnosed in young women. In an analysis stratified for stage of disease, we found no significant difference between 3- and 5-years survival of patients with pregnancies before, during, or after diagnosis and treatment of neoplasia. Due to the inhomogeneity of the subgroups analysed, the question, whether pregnancy has any impact on the outcome of neoplasm could not be conclusively answered. The necessity for the establishment of national and international registries collecting sufficient data about incidence and outcome of patients with pregnancies associated with malignant neoplasms is emphasised.

[The course of pregnancy in patients with malignancies]. / Schwangerschaftsverlauf bei Patientinnen mit Malignomen.

There is a low incidence of pregnancy associated with malignancy. We performed a retrospective analysis of patients of 16 to 35 years of age with malignancies, who had given birth to children in Freiburg 1980-1989. 170 patients were included. 118 patients became pregnant before a malignancy was diagnosed. Malignancy was diagnosed during pregnancy in 24 patients, and 28 patients became pregnant after diagnosis of and therapy for neoplasm. The frequency of preterm delivery, growth retardation and performance of Caesarean section was markedly increased only in patients with concurrent pregnancy and malignancy. 59 children were born after their mother had been treated for a malignancy. Treatment was started during pregnancy in 19 cases. 40 children were born to mothers who became pregnant after treatment. Malformations and abnormalities with respect to the development of the children were observed in similar frequency in both groups and occurred more frequently compared to the group of children, who were born before the treatment of the mother. These results were supported by an analysis of 16 siblings. We conclude, that there is a demand for national and international registries for all pregnancies associated with malignancies. Long-time observation of the children born to mothers, who had been treated for malignancy are necessary.

[Surgical therapy of progressive or recurrent malignant ovarian tumors]. / Operative Therapie progredienter oder rezidivierender maligner Ovarialtumoren.

Out of a total of 120 patients operated on for recurrent ovarian cancer, two at the very best, but possibly not even one, will have a definitive chance of cure. Despite the poor long-term prognosis, as well as the lengthy operation and postoperative treatment involved, it does not seem justified to withhold surgery for recurrent disease totally. In some cases, symptoms can be treated with surgery, such as tumour pain or an impending ileus. In other cases, patients live for 10 years and longer, after multiple operations for relapse, without suffering severe physical symptoms. These are mainly patients with circumscribed, solitary, and very slowly growing tumours, in which cases, it is possible to remove the tumour again and again by surgery. The most relevant prognostic factors include the size of the residual tumour left at the primary operation, the time between the primary operation and the recurrence of the tumour, the type of growth of the recurrent tumour, as well as the extent of the tumour size reduction achieved at the first recurrence operation.
