[Cisplatin, adriamycin and cyclophosphamide combination chemotherapy of epithelial ovarian cancer]

The chemotherapeutic effects of cisplatin + adriamycin + cyclophosphamide (PAC) on 50 epithelial ovarian cancers were compared with the effects of 5-fluorouracil + cyclophosphamide + mitomycin C (FAM) in 17 patients. The cumulative survival at 5 years was 61.1% in all patients, 62.5% in patients treated with PAC and 54.7% in patients treated with FAM. The 5-year survival rate was 100% in Stage I, 63.5% in Stage II, 40.1% in Stage III and 22.2% in Stage IV. Of 22 patients with Stage III and IV treated with PAC, 16 patients responded (8CRs + 8PRs). The median survival duration of the treated patients was 19 months. On the other hand, of 8 patients treated with FAM, only one patient responded (PR). The median survival duration was 7 months. These results indicated the effectiveness of PAC chemotherapy against advanced ovarian cancer. No severe toxicity was observed during treatment with PAC or FAM.

Malignant lymphoma of the uterine cervix. Cytologic diagnosis of a case with immunocytochemical corroboration

The cytologic findings in a case of primary malignant lymphoma of the uterine cervix initially suggested the presence of a malignant neoplasm. By the use of immunologic methods, the lymphoma cells were shown to possess the nature of B lymphocytes. The need for cytochemical study to make a definitive diagnosis of this rare condition is emphasized. The cytologic findings are compared with those of cytologically similar conditions in the cervix: reticulum-cell sarcoma, chloroma and endometrial stromal sarcoma.

Verrucous carcinoma of the uterine cervix: report of a case with follow-up of 6 1/2 years

A case of verrucous carcinoma of the uterine cervix was reported with a long-term follow-up and close observation. The patient was a 73-year-old, Japanese female, who had a suspicious Papanicolaou smear on routine examination. The cervix was replaced by a papillary mass, which was diagnosed as benign papilloma. The patient was followed every 6 months with cytology, colposcopy, and punch biopsy. No cytologic or microscopic diagnosis of invasive squamous cell carcinoma was made during the entire follow-up period. Total abdominal hysterectomy and partial vaginectomy were performed after 6 1/2 years' follow-up, and the tumor was finally diagnosed as verrucous carcinoma. The patient is alive and well 4 years after the operation.

Cytologic findings of ascites from patients with ovarian dysgerminoma

The cytomorphologic observations of ascites from three patients with ovarian dysgerminomas are presented. As compared with those in adenocarcinoma, the cytologic findings in this rare malignant ovarian tumor showed more cells lying isolated or in sheetlike arrangements, fewer cells with discrete cytoplasmic vacuoles, less frequent thickening of the nuclear membrane and more frequent multinucleolation.

Adenocarcinoma of the uterine cervix metastatic from primary stomach cancer. Cytologic findings in six cases

The cytologic features of six cases of stomach cancer metastatic to the uterine cervix are presented. Atypical cells were found in cytology samples from four patients. Fewer atypical cells, larger cellular and nuclear areas, more discrete vacuoles, increased frequencies of thickening of the nuclear membrane and more coarsely granular chromatin patterns were the characteristic cytologic findings of metastatic cervical adenocarcinoma as compared with primary endocervical adenocarcinoma.

Abortifacient effect and uterine cervix-dilating action of 16, 16-dimethyl trans delta 2 PGE1 methyl ester (ONO 802) in the form of a vaginal suppository (a randomized, double-blind, controlled study in the second trimester of pregnancy)

A newly synthesized 16, 16-dimethyl trans delta 2 PGE1 methyl ester (ONO 802) was clinically applied in the form of a vaginal suppository for therapeutic abortion of second trimester pregnancies. Its effects were studied in a double-blind test comparing it with an inactive placebo suppository. The study was conducted at 12 Japanese university hospitals. The number of patients was 125 in total, i.e. 63 receiving ONO 802 vaginal suppository (containing 1.0 mg ONO 802) and 62 receiving inactive placebo suppository. ONO 802 was more effective than placebo with a success rate of 87% (complete (71%) and incomplete (16%) abortions). The onset of uterine contractions was observed in 154.3+/-18.1 min. and the onset of uterine bleeding in 323.6+/-41.0 min. The expulsion of the fetus and placenta was observed in 955.4+/-97.0 and 961.6+/-97.0 min., respectively. The cervix dilating effect of ONO 802 was observed in 63.5% of the patients at 3 hours after the start of administration. Nausea, vomiting, abdominal cramps, diarrhea and pyrexia were noticed. However, all these side effects were transient and mild, requiring no treatment. No abnormality was observed in the puerperal course, duration of uterine bleeding or onset of subsequent menstruation following the therapeutic abortion. Therefore, the present study demonstrated that ONO 802 vaginal suppository was an effective and valuable drug for therapeutic abortion of second trimester pregnancies.

Teratoma of the neck in a newborn infant--a case report

A case of teratoma of the neck in a newborn is presented. Teratoma of the neck is a rare lesion and is mostly found in the newborn, but in some cases in the fetus and stillborn infant. Although in this case prenatal diagnosis was possible via ultrasonography, the infant did not survive because of respiratory distress. Hence, urgent surgery is imperative in such cases.

Teratoma of the neck in a newborn infant - a case report

A case of teratoma of the neck in a newborn baby is presented. Teratoma of the neck is a rare lesion and almost always found in the newborn, but also in the fetus and stillborn infant. Although the mass was found prenatally by ultrasonography in the present case, the patient could not be saved because of respiratory distress. Urgent surgical management is the only way to save life in this kind of neonate.

Birth weight assessed by factor analysis

To investigate the relevancy of birth weight, data on 300 term newborn infants were subjected to a reevaluation of 31 variables related to body measurements of both the mother and child and to the placenta. Factor analysis was introduced to analyze the data obtained. Each group was composed of multiple factor axes, of which factor structures were rather simple in Appropriate for Date (AFD) for approximating the practical images, compared to Heavy for Date (HFD) and Light for Date (LFD). In AFD, the birth weight was thought contributive by the limiting effect of the placenta, independently of the measurements of the mother. We found that the birth weight in itself seems to have a different meaning in each group, and it is difficult to readily categorize the findings on the table of equivalent parameters for labelling of the newborn.

[Cryosurgery for dysplasia, carcinoma in situ, and microinvasive carcinoma of the uterine cervix (author's transl)]

One hundred and three patients with dysplasia, carcinoma in situ, or microinvasive carcinoma of the uterine cervix were treated with cryosurgery during 8 years from 1972 to 1978. Twenty-nine patients underwent several types of operations during 4-41 days (mean 18 days) after cryosurgery, and 74 patients were followed for 3-78 months (mean 3 years) after treatment. Seventy-six per cent of the patients who underwent an operation had residual lesions in their histologic materials. Seventy per cent of the patients who were followed, on the other hand, showed consecutively negative cytology and pathology after cryosurgery. It is necessary for the more effective management of CIN with cryosurgery to perform endocervical curettage in every case, to select small lesion for treatment, and to use more powerful method of cryocauterization.

[Histological grading of hydatidiform mole (author's transl)]

This study was performed to seek possibility of selecting the high risk group in the patients with hydatidiform mole at its delivery. The histologic specimens from 83 patients with hydatidiform mole were reviewed and classified by modified Hertig's grading. Lymphocyte count of peripheral blood was also studied as an immunological index. I. There were 36 Grade I cases, 16 Grade IIa, 23 Grade IIb, and 8 Grade III cases. Two subsequent destructive moles were found from the patients with Grade I, three from Grade IIb, and two from Grade III respectively. The incidence of developing subsequent destructive mole was 6% in Grade I, 8% in Grade II, and 25% in Grade III. II. There was no correlation between histological grading and patients age nor weeks in gestation. When the ratio of syncytiotrophoblast and cytotrophoblast was considered, most of Grade II or III cases were obtained from those in whom the cytotrophoblast prevailed over syncytiotrophoblast. III. The patients with lymphocyte less than 1500/mm3 in their peripheral blood were apt to take abnormal clinical course comparing to those with lymphocyte more than 1501/mm3. The more accurate prediction of clinical course was suggested by combination of histological grading and lymphocyte count.

Nuclear DNA content of trophoblastic tumors

The nuclear DNA content of trophoblasts was measured in 25 cases of normal pregnancy, 46 cases with hydatidiform mole, ten cases with destructive mole and six cases of chorionepithelioma (choriocarcinoma). In normal pregnancy, DNA distribution in syncytiotrophoblasts and cytotrophoblasts showed a sharp peak at the diploid region, although a few cytotrophoblasts with increased DNA content were observed in the first trimester. In chorionepithelioma the DNA content of the trophoblastic cells showed extremely wide distribution without any special peak. In destructive mole, although a wide distribution was observed, the sharp peak was usually noted at the diploid range. Cases with hydatidiform mole were divided into two categories according to the DNA distribution patterns. Type I showed the patterns similar to the first trimester of normal pregnancy and type II resembled the patterns of destructive mole. In hydatidiform mole of type II, subsequent progress towards destructive mole was frequently encountered.
