[Subclinical breast lesions manifested by microcalcifications. Historadiologic correlations. Apropos of a retrospective series of 127 cases].

OBJECTIVE: To ascertain the correlations between the histology and radiology of microcalcifications revealing subclinical carcinoma. TYPE OF STUDY: A retrospective series of 127 exereses of microcalcifications of the breast identified on preoperative radiographs. RESULTS: Histology revealed 43 (33.9%) carcinomas including 72% in situ cancers and 17 borderline lesions (13.3%) for a total of 47.2% cancerous or high risk lesions. 56% of the malignant lesions were diagnosed by mammography during screening. In most cases, conservative treatment was carried out. Axillary node invasion was not found in any of the cases of in situ carcinoma. 16% of the invasive carcinomas were pN+. Re-examination of the radiographs revealed that there was a correlation between the histology and the radiographic findings. 68% (n = 59) of the localizations with less than 30 microcalcifications were benign and 73% (n = 30) were malignant. The triangular appearance of the microcalcification localizations rwas in favour of a carcinoma in 88% (n = 22) cases. The polymorphism microcalcifications within a given localization was suggestive of malignancy in 69% (n = 25%). On the basis of data in the literature, different criteria can be used to provide precise information preoperatively.

[Catamenial sciatic pain due to endometriosis of the sciatic nerve. Review of the literature, apropos of a case].

Sciatic nerve endometriosis is rare but must be included in the sciatic pain aetiology diagnosis. Typically the patient's sciatic pain is cyclic. Electromyography and computed tomographic scanning or nuclear resonance imagery contribute to the diagnosis. Different mechanisms of this localization have been proposed. The patient often requires conservative surgery with excision of endometriosis from the nerve. Medical treatment (LH-RH analogues) may be associated in young patients who need to preserve reproductive function. Total hysterectomy with bilateral salpingo-oophorectomy may be mandatory in stage III or IV endometriosis and older patients.

Primary chemotherapy and radiosurgical breast-conserving treatment for patients with locally advanced operable breast cancers.

PURPOSE: The traditional surgical treatment for operable breast cancer larger than 3 cm is mastectomy. In order to avoid mutilating surgery, we administered primary chemotherapy to 80 patients with operable non metastatic large breast cancer T2 > 3 cm and T3, N0-N1. The purpose of the study was to evaluate the breast-conserving rate induced by this treatment strategy and determine if it is a safe alternative for women with locally advanced breast carcinomas that are responders to an induction chemotherapy. METHODS AND MATERIALS: The mean age was 50.1 years. Forty-three patients were T2 > 3 cm, 37 were T3. Twenty-six were N0 and 54 were N1. Mean tumor size was 5.4 cm. Patients were treated with three courses of the MVCF regimen (Mitoxantrone, Vindesin, Cyclophosphamide, and 5 Fluorouracil) every 4 weeks and then with a radiosurgical combination. RESULTS: The overall response rate to induction chemotherapy was 51% with 17.5% complete tumor regression. Twenty-one percent of the patients developed grade 3 or 4 chemotherapy toxic effects, all acceptable and reversible. Breast-conserving treatment was feasible in 42.5% (34/80). Twenty patients (25%) were treated with a radiosurgical combination (tumorectomy+radiation therapy), 14 (17.5%) with radiotherapy alone (external irradiation and brachytherapy). Age, tumor stage, histology, hormonal status, hormonal receptors rate had no influence on the frequency of the observed regressions. Isolated recurrences occurred in five patients, two conservatively treated and three treated with mastectomy. Metastatic relapses were observed in 20 patients (12% in the responders and 38.5% in the non responders to chemotherapy) (p < 0.02). Five-year actuarial survival was 73% and was significantly better for responders to the induction treatment. CONCLUSION: These results suggest that primary chemotherapy and radiosurgical breast conserving treatment is a safe alternative to mastectomy for patients with locally advanced operable breast cancer. The long-term benefit of this strategy must be evaluated in well designed controlled trials.

Delayed interval delivery in quadruplet pregnancy: a case report.

A case report of delayed delivery of a quadruplet pregnancy is presented. This quadruplet pregnancy resulted from in-vitro fertilization. To our knowledge, this case represents the first report of quadruplets delivered on three separate days using the technique of delayed interval delivery. All infants survived and are healthy 2 years later.

[Small cell carcinoma of the ovary. A clinical and anatomo-pathologic entity].

Small cell carcinoma of the ovary is a rare histological form which is highly malignant. We have decided to consider this as an epithelial tumour after studying it with the optical and the electron microscope. It is however difficult to put it in to a definite type because it is highly undifferentiated. On the clinical level small cell carcinoma is different from other ovarian cancers in several respects. Whereas ovarian tumours usually tend to occur in menopausal women in the fifth or sixth decade of life, small cell carcinomas of the ovary occur mainly in younger women of ages between 10 and 38 years. Furthermore, women who are attacked by this kind of a carcinoma tend to die very soon after the diagnosis has been made without receiving any benefit from the many therapies that have been tried to improve the prognosis. We have studied the condition after seeing two cases of small cell carcinoma in the University Gynaecological Department of Tours, and we have made a study of the literature. We have studied the therapeutic angle for these tumours and we have tried to find out what the best technique will be to cope with this awful prognosis. We discuss whether it might be worthwhile in future to intensify therapy in combination with bone marrow autotransplantation.

[Modeling of feto-placental circulation. Clinical applications apropos of 21 patients having no or inverse diastolic umbilical flow].

The placental resistance index: (S-D)/S (S: represents the amplitude of the systolic peak and D: the amplitude of the telediastolic peak) is constantly inferior to one from the 14th-16th week of amenorrhea during a normal pregnancy. The diastolic umbilical arterial blood flow is continuous because of low placental vascular resistance. From a clinical study of 21 patients with an absent or reversed end diastolic flow in umbilical artery waveforms, an obliterative process in the placental vascular tree was observed. A computer model was used to stimulate the reversed end diastolic flow in umbilical artery waveforms when the placental resistance increased. This haemodynamic approach shows that the placental blood flow decreased, and that the arterial blood pressure, as well as the pulse wave velocity increased when the placental resistance increased. The increase in the difference between the umbilical resistance and the placental resistance caused a reduction of the diastolic flow owing to a progressive increase of the pulse wave velocity reflected. It was concluded that there is a relation between perturbations in placental vascular bed and the flow in umbilical artery waveforms.

[Essential thrombocythemia and pregnancy. A review of the literature].

Essential thrombocythemia is a myeloproliferative syndrome confined to platelet production. Once the character of a megakaryocyte abnormality has been confirmed, the prognosis is good depending on thrombotic and haemorrhagic complications. The authors report the outcome of a pregnancy in a patient who had essential thrombocythemia treated by anti-aggregating drugs from the 10th week of amenorrhoea. In the previous history there were two obstetrical complications of the illness (one spontaneous abortion and one intrauterine fetal death). A caesarean section carried out after 32 weeks of amenorrhoea led to the birth of a baby weighing 1890 gm. Only a few cases have been reported in the literature. There is always a drop in the number of platelets in pregnancy. After delivery the number of platelets becomes pathological within a few weeks. The prognosis for the fetus is linked to the risk of placental thrombosis, not to the numbers of platelets. The problem lies in the choice of indications for the use of acetylsalicylic acid in low dosage, particularly since cases of pregnancy taken to term without any specific type of treatment have been reported.

[Intraepithelial lesions of the cervix uteri and human papillomaviruses: comparative study of histological data and in situ hybridization. Apropos of a series of 77 cervical biopsies].

Seventy seven biopsy samples of cervical mucosa were tested for the presence of human papillomavirus (HPV) by immunohistochemistry and in situ hybridization. From the 38 samples identified as condyloma or cervical intraepithelial neoplasia (CIN), 31 were positive after in situ hybridization and 14 after immunochemical analysis. HPV 6 was found exclusively in condyloma acuminata (2 samples) whereas the HPV 16 probe essentially hybridized with high grade intraepithelial lesions (CIN II, CIN III). Low grade intraepithelial lesions (flat condyloma, CIN I) demonstrated a larger diversity of HPV types (HPV 16, 18, 31, 33). A close correlation was demonstrated between the histologic features of lesions and their HPV 6 or HPV 31 content but not for other HPV types. HPV 31 containing lesions showed a peculiar architecture with numerous, elongated papillae resulting in a spiked appearance.

For a systematic policy of i.v. oxytocin inducted placenta deliveries in a unit where a fairly active management of third stage of labour is yet applied: results of a controlled trial.

The authors analysed the effect of the i.v. oxytocin induced third stage of labour in a controlled trial concerning 1000 patients. The appliance of such an policy in a unit that already had a fairly active management of delivery was very encouraging. The incidence of post-partum haemorrhage (greater than 500 ml) is significantly (P less than 0.001) less than in the control group; and the same for severe haemorrhage. The third stage is significantly (P less than 0.001) shorter in the oxytocin-injected group than in the control group. Moreover, there is no significant difference between the two groups for retained placenta. The economy of blood transfusion, which is a major concern nowadays, could be the real interest of this active management of the third stage of labour.

Prognostic significance of tumor phosphatidylcholine stearic acid level in breast carcinoma.

The involvement of lipid enzymes in the action of oncogenes at the cell membrane level has suggested that membrane lipids could play a role in modulating the growth of tumors. We previously found that breast cancer patients with a low level of polyunsaturated fatty acids in their primary tumor's phosphatidylethanolamine had a high risk of early occurrence of visceral metastasis. In the present study, we prospectively examined whether fatty acid composition of tumor membrane phosphatidylcholine had a prognostic significance in a series of 63 patients with a localized presentation of breast cancer. Membrane phospholipids were extracted from the carcinoma tissue obtained at the time of surgery, phosphatidylcholine was purified, and its fatty acids were analyzed by capillary gas chromatography. During the follow-up period, 20 patients developed metastasis. In these patients, the proportion of stearic acid containing phosphatidylcholine was significantly lower than it was in the tumors of the 43 patients who remained metastasis-free. Multivariate analysis according to Cox showed that low stearic acid level in tumor phosphatidylcholine and high mitotic index were independently predictive of subsequent metastasis. The predictive value of stearic acid level on metastasis risk was higher in node-positive patients than in node-negative patients, allowing individualization of a subgroup of low stearic acid level, node-positive patients with very poor prognosis. We concluded that stearic acid level in tumor membrane phosphatidylcholine is an independent intra-tumor marker of breast cancer prognosis. This finding is new evidence that tumor's structural lipids are linked to the growth of breast cancer.

Disappearance of the in situ component: a criterion predictive of metastasis in breast cancer after local relapse.

Local recurrence after conservative treatment of breast cancer is associated with a significant risk for metastasis. In order to identify criteria predictive of metastasis in this subset of women, we analyzed a series of 35 patients with local relapse among 512 consecutive patients treated with tumorectomy and radiotherapy. When relapse occurred within 2 years of initial treatment, overall 2-year survival from the time of local relapse was 39.5%. When local relapse occurred more than 2 years from initial therapy, 2-year survival was 80.5% (p < 0.001). Pathological slides of both initial and recurrent tumors were reviewed and compared. In 17 patients, local relapse and initial tumor had the same morphological features, with an in-situ component either absent or present in the same proportion. Metastasis occurred in two of these patients. In contrast, 9 of 12 patients in whom the proportion of non-invasive carcinoma had decreased at the time of local recurrence developed metastasis. Overall 2-year survival from the time of relapse was significantly better in the former group of patients (93.3% versus 52.5%, p < 0.05). We concluded that early relapses have a poor prognostic significance and that disappearance of the in-situ component or increase of the invasive component at the time of relapse is a feature predictive of tumor-related death and that more intensive therapy might benefit to this subset of women.

[Are there still indications for an abdominal hysterectomy? 340 cases].

This retrospective study of 340 hysterectomies carried out abdominally concern cases only where the pathology was benign and strictly limited to the body of the uterus. This has made it possible to review the 240 cases carried out for fibroids (70.6%), 63 for simple endometrial hyperplasia (18.5%), 28 for adenomyosis (8.2%) and 9 for atrophy of the endometrium (2.6%). We looked for lesions that could have been treated laparoscopically among these pathologies: submucous fibroids with a diameter of less than 4 cms and where the uterus was less than 10 cms in height and weighted less than 200 g, simple endometrial hyperplasia (the height of the uterus less than 10 cms and the weight less than 200 g, adenomyosis (uterus less than 10 cms in height and less than 200 g weight), this last criteria still "debatable", We found that 110 lesions were selected because they could have been treated conservatively. This means that 32.5% where there seemed to have been indications for hysterectomy out of 340 cases, could have been treated otherwise. These can be divided aetiologically in to: 54 cases of simple hyperplasia of the endometrium (15.9%), 34 cases with submucous fibroids (10.6%), 26 cases of adenomyosis (5.9%). If the cases of adenomyosis are excluded 90 out of 340 hysterectomies carried out abdominally (about a quarter) could have been treated conservatively.(ABSTRACT TRUNCATED AT 250 WORDS)

[Primary adenocarcinoma of the fallopian tube. Retrospective study of 16 cases. Prognostic factors].

The authors report the result of a study carried out on 16 cases of tubal adenocarcinoma treated between the years 1975 and 1988. This is a rare gynaecological cancer with a poor prognosis. The mean age of the patients was 57 years, 64.5% of them were menopausal. 25% had had a history of sterility. 29% were nulliparous and 37.5% had previous salpingitis. In 44% of cases the principal clinical signs were a watery discharge and a blood stained discharge. Pelvic pain occurred in 37% of the cases and CT scan showed a pelvic mass in 50% of cases. Hysterosalpingography and ultrasound were two complimentary investigations. The relatively early stage at which first signs of the condition were noted, show the stages of the disease: stage I 68.7%, stage II 25%, stage III 6.2%, stage IV 0%. Surgery above all was the basis of treatment carried out in all cases, and supplemented in 15 out of the 16 cases by added treatment (radiotherapy, chemotherapy of hormone therapy). As far as histology was concerned, well or moderately well differentiated forms were found to predominate (there were 37.5% grade I and 37.5% grade II) against only 26% for grade III. More than half of the tube wall was infiltrated in 50% of cases. The actuarial survival rate after 5 years was 33%. The authors examine the principal factors responsible for the prognosis, the tissue, the early diagnosis and the possibility of removing the tumour completely at the first operation as well as the histological grading and above all the degree of depth of infiltration of the wall of the tube.
