Placental insufficiency and maternal death caused by advanced stage of breast cancer in third trimester.

We describe a case with placental, and general metastases, resulting in transient intrauterine and general hypoxia, and with additionally clinical features similar to HELLP syndrome. A patient in the third trimester with dyspnea at rest developed right heart failure during c-section. During emergency thoracotomy the patient went into generalized shock and died after intense CPR. Placental insufficiency was based on a multilocal metastatic event, decreasing the utero-placental perfusion.

Influence of acupuncture on duration of labor.

The aim of this case control study was to evaluate the thus far controversially discussed influence of acupuncture (AP) on the duration of labor. Fifty-seven women with AP treatment (group A) were included in our study after spontaneous vaginal full-term delivery. The control group included 63 women (group B). Median duration of the first stage of labor was 196 min in group A and 321 min in group B (Wilcoxon 2-sample test, p < 0.0001). Median duration of the second stage of labor was 57 min in group A and 57 min in group B (Wilcoxon 2-sample test, p = 0.82). Thirty women had a premature rupture of the membranes (PROM), in group A 66.7% and in group B 33.3% (chi2 test, p = 0.02). Women without AP (group B) received significantly more often oxytocin during the first stage of labor compared with group A women (85 and 15%, respectively, chi2 test, p = 0.01) as well as during the second stage of labor (72 and 28%, respectively, chi2 test, p = 0.03). Our study suggests that AP treatment is a recommendable form of childbirth preparation due to its positive effect on the duration of labor, namely by shortening the first stage of labor.

[The prognostic effect of scintigraphy-guided lymphadenectomy in therapy of stage Ib cervix carcinoma]. / Uber den prognostischen Einfluss der Szintigraphie-geleiteten Lymphadenektomie in der Therapie des Zervixkarzinoms im Stadium Ib.

In a retrospective study the survival rates of 161 patients with stage Ib cervical cancer after radical operation (Latzko, Wertheim-Meigs) including complete or incomplete pelvine lymphadenectomy were compared. To increase radicality of lymphadenectomy, preoperative targeting of pelvic lymph nodes was done in all the patients using 99mTc-Sb2S3 radiocolloid. Intraoperatively, a gamma-camera being integral part of an operating table allowed delineation and scintigraphy-guided resection of pelvic lymph nodes. Dependent on the evidence of remaining pelvine foci of radioactivity at the end of the operation, lymphadenectomy was assessed as complete or incomplete. Mean observation time of completely lymphadenectomised patients (n = 117,72.67%) were 80 months (5-169 months) and 42 months (1-149 months) of the incompletely lymphadenectomised patients (n = 44,27.33%). In 28 (23.93%) completely lymphadenectomised patients against only 5 (11.36%) patients with incomplete lymphadenectomy, lymph node metastases were proved histologically. Five year-survival rate of completely lymphadenectomised patients was 85.47% and 88.64% of incompletely lymphadenectomised patients (not significant, Mantel-Test). Also, selective comparison of lymph node-positive patients did not suggest a divergent trend indicated by 13 (46.43%) deaths of completely and 3 (60.0%) deaths of the incompletely lymphadenectomised patients after an observation of five years. The technique of scintigraphy-guided pelvic lymphadenectomy using 99mTc-Sb2S3 radiocolloid cannot be expected to improve prognosis of patients with cervical cancer stage Ib.

Hystero-salpingo scintigraphy: a routine investigation in sterile women?

Based on the spontaneous migration of radioactive tracer from the posterior vaginal fornix to the ovaries and peritoneal cavity, several attempts were made to assess hystero-salpingo scintigraphy (HSS). The low acceptance rate by sterile women of routine investigation of tubal function may be due to a fear of radiation exposure and unpleasant examination procedures. Our protocol for HSS adopts a low dose of radioactive tracer (0.2-0.3 mCi), a defined mode of application (between the external and internal os of the cervical canal) and a short imaging time (60 min). From 1990 to 1992, we investigated 60 fallopian tubes in 32 sterile women by HSS, hystero-salpingography (HSG) and/or chromopertubation during laparoscopy (LPSC). The results of HSG and HSS corresponded in 15 of 49 fallopian tubes, LPSC and HSS in 9 of 24. None of the 32 patients had become pregnant naturally during the average observation period of 17 months. Two patients became pregnant after in-vitro fertilization. HSS, performed according to our protocol, causes less pain and results in a lower dose of radiation than HSG (about 50%). It is well accepted by patients and is easy to perform. As an investigation of tubal function, HSS may serve as an additional examination technique in cases of presumed tubal sterility.

[Conisation in stage Ia cervix cancer]. / Die Konisation beim Zervixkarzinom im Stadium Ia.

Between 1975 and 1988, a total of 78 patients suffering from cervical cancer stage Ia were treated by conisation based on a positive smear. According to FIGO, these 78 patients consisted of 53 (67.9%) stage Ia1 and 25 (32.1%) stage Ia2 cases. Complete removal of the tumour by conisation was achieved in 51 patients. In 23 cases (29.5%) the margin of resection was reached by a carcinoma in situ, in 4 cases (5.1%) invasive carcinoma was found. Conisation was not followed by further surgery in 10/51 patients with complete tumour removal. One patient (1/23) with incomplete removal underwent surgery elsewhere. In the other 67/78 patients following hysterectomy, the pathologist diagnosed three cases of cervical cancer, 11 cases of carcinoma in situ and 53 cases (67.9%) without pathological findings. Carcinoma in situ after hysterectomy was found in only 2 cases (4.9%) with primarily free resection margins of the conus. Among the 27 patients with carcinoma in situ or invasive carcinoma reaching the conus margin, 9 cases of carcinoma in situ and 3 invasive carcinomas were diagnosed histologically after hysterectomy and one patient underwent surgery elsewhere. In this study, the value of conisation as single therapy of cervical cancer stage Ia1 and stage Ia2 with good prognosis (depth of infiltration of < 3 mm and no invasion of blood vessels) is discussed and the importance of thorough and exact histological examination is emphasised.

Combined use of 123I-labelled BCD-F9 and 4C4 monoclonal antibody with dissimilar specificity for breast cancer: implication for the detection limit of immunolymphoscintigraphy in the assessment of axillary lymph node metastases.

To determine whether the detection limit of immunolymphoscintigraphy (ILS), reported to be > or = 1 cm, can be improved by comparing imaging after administration of breast cancer-specific monoclonal antibody (MAb) BCD-F9 and breast cancer-nonspecific 4C4, 25 patients with suspected breast cancer were given injections of both 123I-labelled MAbs. The ILS was performed independently for both MAbs, the 4C4 scans serving as an ipsilateral negative control, and was used preoperatively to detect lymph node metastases. Twenty-one patients had breast cancer of whom 11 patients suffered from axillary involvement. Single interpretation of BCD-F9 scans gave true positive results in six of 11 and true negative results in 12 of 14 patients, whereas combined interpretation of BCD-F9 and 4C4 scans gave true positive results in nine of 11 and true negative results in 14 of 14 patients. On the basis of comparison of scintigrams of both MAbs, ILS allowed the detection of lymph node metastases 0.3-0.8 cm in diameter (n = 3). Immunohistochemistry of BCD-F9 and 4C4 MAbs of tumour-free and tumour-bearing lymph nodes correlated with ILS, with the exception of one patient. The study suggests that comparing scans obtained with BCD-F9 and 4C4 MAbs may improve the detection limit of ILS in the preoperative staging of axillae.

Etoposide and carboplatin as salvage and first-line therapy in ovarian cancer patients.

BACKGROUND: The agents etoposide and carboplatin are active against ovarian cancer and display synergistic anti-tumor activity in animal tumor models. The objective of these two phase II trials was to determine the efficacy and toxicity of the combination of etoposide with carboplatin in previously treated and untreated patients with ovarian cancer. PATIENTS AND METHODS: Etoposide (100 mg/m2) was administered as a one-hour infusion on three consecutive days and carboplatin (400 mg/m2) as a 30-minute infusion on day 2 of each monthly scheduled cycle. In 20 patients, previously treated with cisplatin-containing regimens, a total of 102 cycles was applied as salvage therapy (ST) and in 27 patients, a total of 168 cycles as first-line therapy (FLT). RESULTS: ST yielded 2 complete remissions (CR) and one partial remission (PR); in 7 patients, no evidence of disease (NED) and in 6 patients, no change (NC) were observed. The progression-free intervals (PFI) lasted a median 7.0 months (range < 2-14 months). FLT resulted in 7 CR (4 of them pathologically (p) verified), 11 NED (1 pNED), 3 PR (1 pPR) and 6 NC. The objective response rate was 63% (95% confidence interval: 36-89%). PFI lasted a median 8.0 months (range 3-25+ months); median survival had not been reached at the time of evaluation. Thrombocytopenia (WHO grade 4) was the limiting toxicity. CONCLUSIONS: Although not fulfilling the expectations of synergistic activity as shown in preclinical models, the combination of etoposide with carboplatin is an active and feasible therapy regimen in the out-patient management of ovarian cancer.

[Isotope nephrogram in follow-up of radically operated cervix cancers]. / Isotopennephrogramm in der Verlaufskontrolle radikal operierter Zervixkarzinome.

257 patients suffering from cervical cancer (stage I and II according to FIGO classification) were included in this retrospective study. All of them underwent radical surgery between 1978 and 1987, including pelvic lymphadenectomy. In addition to conventional follow-up procedures, isotope nephrograms (ING) were performed as a routine measure. ING curves reflect renal function and serve as a highly sensitive qualitative parameter of urine flow. It may therefore be used as indirect indicator of pathologic changes in the small pelvis, such as recurrent disease. Follow-up period was between 3 and 10 years. Chi-square test was used to determine the probability of correlation between the evidence of pathologic ING-curves (yes/no) and a) lymph node status (pos/neg), b) patients, who underwent adjuvant radiotherapy (yes/no), or c) patients, who revealed recurrent disease (yes, no). All of the subgroups showed significant positive correlation. Pathological ING curves appeared a) in 61% of patients having a positive lymph node status (n = 66, p = 0.001), in 88% of patients, who developed recurrent disease (n = 56, p = 0.001) and in 44% of patients, who received adjuvant irradiation therapy (n = 131, p = 0.05). The high degree of sensitivity of ING concerning urinary tract obstruction seems to justify the routine use of this method in the follow-up of these patients. It should help to identify impaired renal function in good time.

Prognostic factors related to recurrent endometrial carcinoma following initial surgery.

Site of recurrence and histological type are significant prognostic factors for survival in recurrent endometrial carcinoma. The aim of this retrospective analysis of 56 patients suffering from recurrences of endometrial carcinoma following initial surgery was to establish the prognostic relevance that the following factors had on the survival rate: age, primary tumor stage, histological assessment (papillary vs non-papillary), postoperative adjuvant radiation therapy, recurrence free interval (< 24 months, > 24 months) and localisation of recurrence. The univariate analysis showed a significantly longer median survival time after recurrence for the following parameters: local recurrence vs extra vaginal recurrence (77.5 months vs 15.7 months, p = 0.02), non-papillary vs papillary carcinoma (36.1 months vs 7.7 months, p = 0.02), no adjuvant irradiation vs adjuvant irradiation (82.0 months vs 8.8 months, p = 0.007). Patients after adjuvant radiation treatment and patients suffering from papillary carcinomas have a significantly higher proportion of patients with distant metastasis (patients with adjuvant radiation treatment: Chi-square test: p = 0.001; patients suffering from papillary carcinomas: p = 0.033). In the case of local recurrences, a three year survival rate of 54% can be achieved with radiation treatment. Recurrences of papillary endometrial carcinomas and patients suffering from distant metastasis on the other hand, show very low survival rates if they are treated with radiation therapy (papillary carcinomas: three-year survival rate of 18%, patients suffering from distant metastasis: 19%). These patients should be included in randomised studies with a view to examining the therapeutic effects of either additional or exclusive treatment with chemotherapy.

[Ovarian cancer after hysterectomy]. / Ovarialkarzinom nach Hysterektomie.

Between 1978 and 1988 we treated 538 patients at our department because of ovarian cancer. Among them were 37 patients, who had undergone hysterectomy before. When ovarian cancer was diagnosed, 28/37 were already in stage III or IV according to the FIGO classification (75.7%). Theoretically in 37/538 (6.8%) of our patients ovarian cancer could have been prevented by prophylactic oophorectomy during the previous hysterectomy performed because of other reasons. Current possibilities of hormone replacement could facilitate such a decision in individual cases.

Goserelin a GnRH-analogue as third-line therapy of refractory epithelial ovarian cancer.

Between October 1988 and March 1991, 23 ovarian cancer patients with progressive disease whilst receiving second- or third-line polychemotherapy received subcutaneously 3.6 mg Goserelin, a GnRH analogue, at monthly intervals until further tumor progression. Four patients (17.4%) achieved partial response, 7 patients (30.4%) had stable disease and 12 patients (52.2%) showed further tumor progression. Median time to tumor progression was 8.5, 5.3 and 2.1 months, respectively (Mantel test, P = 0.0003). Ten out of 11 patients who showed partial response or no change had grade 2 or grade 3 tumors. We conclude that Goserelin shows evidence of antitumor activity also in grade 2 and grade 3 ovarian carcinoma. It offers a therapeutic alternative to a group of patients, in whom we usually terminate cytotoxic treatment.

[Prognostic factors of radically operated stage Ib cervix cancer]. / Prognosefaktoren des radikal operierten Zervixkarzinoms im Stadium Ib.

The present retrospective study attempts to evaluate the significance of factors such as age, histological type, histological grading, tumour size, lymph node metastases and tumour infiltration of the corpus uteri. Between 1975 and 1988, 312 patients were operated at our department or referred to postoperative radiotherapy. They fulfilled the inclusion criteria: histopathological stage Ib and radical hysterectomy with pelvic lymphadenectomy. The multivariate analysis confirmed, that the factors histological grading (G3 vs G1 + G2: relative risk (RR) = 2.66; 95% confidence interval (CI) = 1.36-5.18), tumour size (tumour infiltration of the cervix greater than 2/3 vs less than 2/3: RR = 2.36; 95% CI = 1.07-5.17), and pelvic lymph node metastases (positive vs negative: RR = 5.36; 95% CI = 2.70-10.65) are of significant importance for the survival. The results show, that patients with a cervical carcinoma in FIGO stage IB, with an infiltration of more than two thirds of the cervix with a more or less differentiation and with or without positive lymph node status, should be classified as high risk patients. In these unfavourable situations, a prospective randomised study should clarify the success rate of adjuvant therapy.

[Lymphoscintigraphy with (123)I-marked epidermal growth factor in cervix cancer]. / Lymphszintigraphie mit 123I-markiertem epidermalem Wachstumsfaktor beim Zervixkarzinom.

Several malignant neoplasms express high levels of epidermal growth factor receptors. The aim of this study was to assess whether 123I-labeled epidermal growth factor can concentrate in lymph node metastases of squamous cell carcinomas of the cervix. 14 patients with advanced cervical cancer were selected because of their high probability of lymph node metastases. Planar scintigrams were recorded from the lower and upper abdomen following subcutaneous injection of 123I-labeled epidermal growth factor into the web space of each foot. Scintigraphic images were interpreted without knowledge of computerized tomography scan (n = 13) and ultrasound (n = 9) results from the pelvic lymph nodes. In 2 patients, histological verification was performed by diagnostic biopsy of pelvic lymph nodes. Nodal involvement was confirmed by computerized tomography for 4 of the 11 positive scans and by ultrasound for 2. In 11 out of 14 patients an increased uptake of 123I-labeled epidermal growth factor could also be seen in the primary tumour. Our findings suggest that targeting of cervical cancer lymph node metastases can be achieved by in vivo binding of 123I-labeled epidermal growth factor with receptors on tumour cell surfaces.

Is CA-125 monitoring useful in patients with epithelial ovarian carcinoma and preoperative negative CA-125 serum levels?

Between December 1983 and December 1988 we examined the postoperative tumor marker development and correlated this to the clinical course of the disease in 56 patients suffering from primary epithelial ovarian carcinoma of International Federation of Gynecology and Obstetrics stages I-III and with a preoperative CA-125 serum level less than or equal to 65 U/ml. In 54% of all cases there was a reduction of more than 50% of the CA-125 serum level within the first 3 months after surgery. Nine out of thirteen patients with progressive disease (69%) showed an increasing CA-125 serum level with a median lead time of 6 months (0-11 months) prior to clinical diagnosis. These preliminary results indicate that the monitoring of cancer patients with CA-125 tumor marker seems to be a useful method of early diagnosis of progressive disease even in patients with preoperative serum levels lower than 65 U/ml.

Body temperature and respiratory rate of lactating dairy cattle under field and chamber conditions.

A coordinated field and chamber experiment assessed breed, sire, and cow differences in body temperatures and respiratory rates. During each of 4 yr, 10 lactating Ayrshire, Guernsey, Holstein, and Jersey cows, 40 animals per yr, were observed in the field on 10 d when the air temperature approached 32 degrees C. For the first 3 yr, each cow also was exposed in a controlled atmospheric chamber at 40 degrees C and 34 mm Hg vapor pressure. Significant breed differences were found for body temperature and respiratory rate. The order of tolerance to hot conditions was Jersey, Guernsey, Ayrshire, and Holstein both in the field and chamber. Significant sire differences, interpreted as genetic, were found for the field measures but not in the chamber. Repeatability of individual field observations for a cow on different days in a year ranged from .38 to .55. Correlations between the average of 10 observations for a cow in the field during a year and the chamber evaluation were positive but lower than the repeatability values. Correlations of ambient temperature with body temperatures and respiratory rates were highest; those for radiation were next, followed by vapor pressure and air movement.

[Cervix carcinoma in pregnancy]. / Das Zervixkarzinom in der Schwangerschaft.

In this retrospective study we discuss 12 cases of cervical cancer diagnosed during pregnancy. At the time of diagnosis of cervical cancer 11/12 patients were older than 29 years. According to FIGO 3/12 cases were in stage Ia1 cervical carcinoma and 9/12 in stage Ib. After a follow up of at least 35 months no recurrence occurred. We believe, that pregnancy has no negative effect on prognosis of cervical cancer.

[Effects of primary radiotherapy on uterine circulation in advanced cervix cancer]. / Die Auswirkungen einer primären Strahlentherapie auf die Uterusdurchblutung bei fortgeschrittenen Zervixkarzinomen.

We examined 11 patients suffering from advanced cervical carcinomas, who were treated primarily with radiation. The blood flow through the uterus was established by measuring the Doppler pulse flow through the arteria uterina before and after radiotherapy. In a reference group of 25 women, free from cervical carcinomas, we established a median PI of the arteria uterina of 3.52 (+/- 1.10) with values between 1.64 and 5.06. In contrast, the group of 11 patients suffering from inoperable cervical carcinomas, were found to have a PI of 1.80 (+/- 1.40), with values between 0.41 and 4.41 (Wilcoxon Test: p = 0.001). After completion of the radiotherapy, 7 of the 11 patients showed no measurable pulsations of the arteria uterina, 3 patients had only systolic blood flow and only one patient had the same unchangingly high rate of blood flow as registered before radiotherapy. The significantly reduced flow of blood through the tumour tissue after radiotherapy, indicates a very limited response to chemotherapy. Therefore, chemotherapy should be administered before radiotherapy.

[Ferritin level in newborn infants after prepartal iron medication]. / Ferritinspiegel von Neugeborenen nach präpartaler Eisenmedikation.

Aim of the study was to find out the influence of iron medication of pregnant women on the iron levels of their newborn. In a prospective randomised study the iron-substituted group (n = 57) was treated with 2 x 1 Aktiferrin comp. Kps. (Merckle) during pregnancy, starting from the 22nd week. The control group (n = 46) had no medication during pregnancy. The substituted group had statistically significantly higher serum ferritin levels in the 30th week of pregnancy (p less than 0.048), higher levels measured in the cord blood at birth (p less than 0.001), and also the newborn of this group had statistically significant higher serum ferritin levels than the newborn of the control group (p less than 0.001). Our conclusion is that prepartal iron medication leads to increased iron stores in the newborn.
