[Comparison of temperature measurements during laparoscopic sterilization and the histologic findings of the cauterized segments of the fallopian tube (author's transl)].

During laparotomies the temperature generated by tubal sterilization with the laparoscopic equipment was measured continually in 32 fallopian tubes. The thermal damage to the fallopian tube caused by different energies and coagulation durations was examined microscopically. During the coagulation of the fallopian tube, with an energy of 20-30 watt temperatures of around 100 degrees C are produced at the point of coagulation. The effective coagulation time is dependant upon the energy created and the duration of the coagulation. The best histologic results were obtained with a duration of the coagulation of 60 seconds at an energy of 30 watts. This corresponds to an effective coagulation time of 50 seconds. The temperature of the coagulation instrument becomes normal within 1 to 2 minutes after the coagulation. If the electric energy is increased to 50 or 100 watt, sparking is observed almost consistently. With these energies, temperatures up to 600 degrees C are observed. The temperature of the metal parts of the coagulation forceps then become normal after 3-4 minutes. In order to avoid burns during laparoscopic tubal sterilizations and in order to obtain a good histologic result the procedure should be done with an electrical energy of 30 watt and a duration of the coagulation of 60 seconds.

[Carcinoma of fallopian tubes. Presentation of 2 cases].

The carcinoma of the Fallopian tube is at the present time, one of the most rare gynecologic tumors, representing approximately less than 1% in world literature, being in our experience of 0.15%. We presented two cases of adenocarcinoma of the Fallopian tube, seen in a lapse of 25 years, not diagnosed preoperatorily with the clinical trial of abnormal bleeding, negative biopsy of endometrium and adnexal mass. As it is written in the literature, the diagnosis is rarely established previous to the operation and it usually corresponded to an adenocarcinoma. The classification of the FIGO for the stage is used. In relation to the survival follow-up: the stages I and II present 60% approximately of survival to the five years and it is suggested radiotherapy additional to the surgery; however, according to some authors this doesn't improve the survival.

Morphology of metastatic cancer of the fallopian tube in uterine cervix carcinoma.

Morphological examination of 452 Fallopian tubes removed together with the uterus for uterine cervix cancer revealed in 221 patients at the time of operation and in 5 dead on autopsy, metastatic cancer in 8 females (3.5%) in 12 tubes (right-side involvement 2 cases, left-side 2 cases, ambi-lateral 4 instances). In 37 patients there were metastases in inner organs; of these diseased 21.6% were affected by metastatic cancer of the Fallopian tube. Macroscopically, metastatic tumors were of different form in 4 cases; in the remaining instances they were only discovered on microscopical examination. In two cases the tubes were affected in their whole length, in the other case the tumor was located in the ampullary portion. The cyto- and histological structures of the metastatic cancer were the same as those of the primary uterine cervix tumor. The predominating route of tumor dissemination has proved to be lymphogenic propagation (5 cases). In two cases lymphohematogenic dissemination, in one case propagation by implantation were observed.

Transitional cell carcinoma of the fallopian tube: a light and electron microscopic study.

Carcinomas other than adenocarcinomas are extremely rare in the fallopian tube. We report a case of a malignant neoplasm of the fallopian tube with histological features of transitional cell carcinoma that presumably arose from an extraluminal region of the tube. A 57-year-old postmenopausal woman with vaginal bleeding was found to have a left adnexal tumor. Exploratory laparotomy revealed a left tubal tumor with a metastatic nodule on the rectal surface. Histologically, the tumor surrounded the lumen of the left fallopian tube and was composed of cells with "coffee-bean"-like nuclei arranged in solid nests without keratinization. No abnormalities were found in the right tube, ovaries, or uterus. Electron microscopy revealed the tumor cells to have nuclei with deep nuclear indentations, cytoplasmic tonofilaments, and intercellular spaces with prominent interdigitations of the cell membrane. In addition, several tumor cells with protruding microvilli formed abortive lumina. These histological and ultrastructural features were consistent with the diagnosis of transitional cell carcinoma.

Laparoscopic approach to an uncommon adnexal neoplasm associated with infertility: serous cystadenofibroma of the fallopian tube.

A rare case of serous cystadenofibroma of the fallopian tube was discovered during evaluation for in vitro fertilization-embryo transfer. Bilateral tubal occlusion was noted on hysterosalpingogram, and a right adnexal cyst, initially thought to be of ovarian origin, was identified by office transvaginal sonography. Laparoscopy revealed a 5.5-cm, fluid-filled mass involving the distal aspect of the right fallopian tube. Both ovaries and uterine exterior appeared grossly normal. The cyst was decompressed and removed intact without incident through a 5-mm laparoscopic cannula. The mass showed histologic features consistent with benign serous cystadenofibroma. The patient had an uncomplicated postoperative convalescence and continued to do well 3 months after surgery.

Immunohistochemical staining for CA-125 in fallopian tube carcinomas.

From 1981-1991, 15 patients with primary fallopian tube carcinomas were treated at the University of Kentucky Medical Center. Immunohistochemical staining for CA-125 was performed on tumor specimens from all cases. Thirteen tumors (87%) stained positively for CA-125. Antigen staining was most intense in the apical portions of carcinoma cells. Serum CA-125 levels were measured in 5 patients and were elevated in 4 (80%). There was a positive correlation between tumor and serum antigen expression in these cases. Serum CA-125 levels accurately reflected disease status in the patients studied. These data suggest that CA-125 is a useful marker in patients with fallopian tube carcinoma. Immunohistochemical localization of CA-125 in tumor tissue should predict which patients will benefit most from serial antigen determinations.

Treatment of primary fallopian tube carcinoma with cisplatin-containing chemotherapy.

Because of the rarity of the primary fallopian tube carcinoma, optimal primary therapy is still not well defined, and there is little information available regarding the efficacy of combination chemotherapy in advanced disease. The experience obtained by treating 14 patients with fallopian tube carcinoma--most of them with advanced disease--using a combination of cisplatin, adriamycin, and cyclophosphamide (CAP) (10 patients) or carboplatin plus cyclophosphamide (4 patients) is reported. One patient had Stage Ic disease, 2 had Stage II, 9 had Stage III, and 2 had Stage IV. Eleven patients had clinically measurable disease (> 2 cm) at the start of chemotherapy. Eight of these patients had a complete clinical response (CR), 2 had partial response (PR), and 1 had progressive disease (PD). Of the 8 CR patients, 5 underwent second-look operation (SLO). Pathological complete response (pCR) confirmed in 4 out of 5 patients at SLO. The 3 patients without measurable disease (< 2 cm) after primary surgery had an indeterminate response to chemotherapy. Two of them (Stages Ic and II, respectively) had a negative SLO, while the third patient with Stage IV disease, who refused the SLO, remains disease-free 41+ months. This high response rate shows that this carcinoma is very responsive to cisplatin- or cisplatin analogue-containing regimens. One pCR and two clinical CR patients relapsed after 20, 14, and 16 months, respectively, from the completion of chemotherapy and died despite the second-line treatment. The toxicity of the regimens was moderate. The median survival was 40 months, and the actuarial 5-year survival rate was 48%. Carcinoma of the fallopian tube appears to respond favorably to cisplatin- or carboplatin-containing chemotherapy.

The management of primary fallopian tube carcinoma.

The outcome of 30 patients with primary fallopian tube carcinoma is described. Treatment varied over the 22 year period of accrual and included combinations of surgery, radiotherapy and chemotherapy. There was an apparent increase in stage at treatment with time which was probably related to more precise staging at laparotomy and the greater use of computerized tomography. The median survival for all patients was 28 months and the 5-year survival was 18%. Ten patients received postoperative chemotherapy for residual disease with an overall response rate of 80% and median progression-free and overall survival times of 14 and 21 months respectively. The pattern of relapse was similar to that seen in ovarian carcinoma, with all but one patient having the pelvis or abdomen as the main site of recurrence. Primary fallopian tube carcinoma has a response to treatment and a tumour biology similar to that of ovarian carcinoma. It is recommended that the management of this uncommon malignancy should continue to be along the lines of ovarian carcinoma, with initial treatment by cytoreductive surgery followed by chemotherapy or radiotherapy for residual disease.

Carcinoma in situ of the Fallopian tube associated with cervical carcinoma. Case report.

A case of carcinoma in situ of the fallopian tube in a 55-year-old woman, associated to cervical carcinoma is described. The necessary criteria for the diagnosis of pre-invasive carcinoma of the fallopian tube, among which the number of mitoses seems to be of great importance, are discussed. This previously unreported association of carcinoma in situ of the fallopian tube, with carcinoma of the uterine cervix, emphasizes the notion of the multicentric neoplastic possibilities of the müllerian tract derivatives.

Salpingoscopy. A method for direct examination of the fallopian tube.

Using flexible endoscopes 0.6-2.3 mm in diameter, direct tubal endoscopy was performed on human uteri and fallopian tubes ex vivo. Fourteen studies were performed both transcervically using the operating channel of a hysteroscope and transtubally via the fimbriae of the Fallopian tube. Different anatomic segments of the fallopian tube were readily identified, as was a possible tubal "sphincter" not previously described. This technique holds great promise for the evaluation and potential treatment of intratubal pathology in the gynecologist's office.

Preoperative diagnosis of the primary fallopian tube carcinoma by three-dimensional static and power Doppler sonography.

OBJECTIVE: To investigate whether three-dimensional static and power Doppler ultrasound improves the diagnosis of primary Fallopian tube carcinoma. METHODS: During a 2-year period five cases of primary Fallopian tube carcinoma were selected from a cohort of 520 patients with a previous scan suggestive of an adnexal tumor. RESULTS: Tubal malignancy occurred in patients between 49 and 64 years, with presenting symptoms such as pain, vaginal bleeding and leukorrhea. CA 125 was elevated in three cases of tubal carcinoma with stages II and III, while in two patients with stage I, CA 125 was within the normal limits. Two-dimensional ultrasound demonstrated sausage shaped cystic masses with papillary projections in two patients and a complex adnexal mass in one patient. Three-dimensional ultrasound revealed sausage shaped cystic and/or complex masses with papillary projections in all five cases of tubal malignancy. In one patient preoperative 3-D ultrasound correctly predicted bilateral tumors, while 2-D transvaginal sonography found only unilateral changes. Additional 3-D power Doppler examination depicted vascular geometry typical for malignant tumor vessels such as arteriovenous shunts, microaneurysms, tumoral lakes, blind ends and dichotomous branching in each of the cases with Fallopian tube carcinoma. CONCLUSIONS: Three-dimensional ultrasound allows precise depiction of tubal wall irregularities such as papillary protrusions and pseudosepta. Improved understanding of anatomical relationships may aid in distinguishing ovarian from tubal pathology. Multiple sections of the tubal sausage like structures enable determination of local tumor spread and capsule infiltration. Study of the vascular architecture in cases of Fallopian tube malignancy is further enhanced using 3-D power Doppler imaging.

Epithelial hyperplasia of the fallopian tube. Its association with serous borderline tumors of the ovary.

We examined sections of fallopian tube from 99 patients with serous borderline tumors of the ovary (SBT) to determine the prevalence of epithelial hyperplasia. Fifty-eight patients with carcinoma of the cervix (CC) and 30 with grade 2 or 3 ovarian carcinoma (OC) served as controls. Patient ages were similar in each group. Epithelial hyperplasia was identified in 68 of 99 patients with SBT (68.7%), compared with 15 of 58 with CC (25.9%) and 4 of 30 with OC (13.3%). Epithelial thickness and nuclear crowding were greater in hyperplastic than in normal fallopian tubes. There was no correlation between hyperplasia and menstrual cycle. In patients with SBT, the presence of epithelial hyperplasia correlated with tumor stage. Hyperplasia was present in 38 of 60 (63%) patients with Stage I tumors. In Stage II and III tumors, hyperplasia was present in 18 of 25 (72%) patients with noninvasive peritoneal implants and 12 of 14 (86%) with invasive implants. Fallopian tube epithelial hyperplasia may represent an example of a field effect in müllerian carcinogenesis.

Effect of lengthening the fallopian tube on fertility in the rabbit.

The effect of surgically lengthening the rabbit oviduct was investigated. In the study group, a lengthened fallopian tube was created by division of the left fallopian tube at the ampullary-isthmic junction and the right fallopian tube at the uterotubal junction. The proximal left tube and the entire right tube were mobilized to the midline, and a microsurgical anastomosis was performed with 10-0 nylon. This formed a tube that was lengthened by approximately 50%, with doubling of the isthmic region. In the control group, both tubes were divided at the ampullary-isthmic junction, and the proximal left and distal right segments were joined to form a tube of normal length. The left ovary and ampulla were resected in both groups. After the animal had been bred, a second laparotomy was performed to assess adhesion formation, document tubal patency, and establish a nidation index. The median nidation index of the control group (N = 11) was 0.89, whereas that of the lengthened group (N = 7) was 0. The nidation indices of the two groups were different, with P less than 0.01.

Ovarian follicular fluid, progesterone and Ca2+ ion influences on sperm release from the fallopian tube reservoir.

As a means of determining whether ovarian follicular fluid reaches the functional sperm reservoir in the caudal isthmus of the Fallopian tube shortly after ovulation, 0.01-0.02 ml aliquots of whole or steroid-free follicular fluid were introduced into the distal extremity of the isthmus within 1 hr before ovulation. Eggs were recovered during a second intervention 4 hr 45 min-6 hr 10 min after treatment and examined by phase-contrast microscopy for the normality of fertilisation. In a separate experiment, 0.01-0.02 ml aliquots of 10 microM calcium ionophore solution were introduced into the same site in comparable animals. Sixty-nine fertilised eggs were recovered from 12 fallopian tubes treated with whole follicular fluid, of which 24 (34.8%) were polyspermic. The 12 contralateral control tubes (PBS-treated) yielded 47 fertilised eggs, of which only one (2.1%) was polyspermic (P < 0.001). Steroid-free aliquots of the same follicular fluid introduced bilaterally into eight fallopian tubes (4 animals) resulted in recovery of 59 fertilised eggs, of which only one (1.7%) was polyspermic. Treatment with ionophore solution yielded a 41.6% incidence of polyspermy (10 of 24 eggs from four tubes) compared with 3.8% polyspermy (1 egg) from the control tubes (P < 0.01). Dispermy was the principal form of polyspermy. The numbers of accessory spermatozoa on/in the zona pellucida were increased by the experimental treatment. Follicular fluid passing down the fallopian tube ampulla at ovulation was therefore considered not to be the physiological stimulus for an initial, tightly-controlled release of spermatozoa from epithelial binding in the caudal isthmus. Indeed, because such sperm activation commences shortly before ovulation, a locally transmitted ovarian programming with relatively high concentrations of follicular hormones remains the favoured model. Although pre-ovulatory progesterone is considered to be the coordinating steroid of increasing influence in these pre-fertilisation events, its effects are proposed to be modulated in the endosalpinx by mobilisation of Ca2+ ions into a discrete population of bound spermatozoa. Results of the steroid-free follicular fluid and calcium ionophore treatments stand in support.

BRCA2 germline mutations in primary cancer of the fallopian tube.

Germline mutations of BRCA1 and BRCA2 genes confer susceptibility to breast and ovarian cancer. It has been recently reported that BRCA1/2 mutations may also predispose to fallopian tube cancer. We report the presence of germline BRCA2 gene mutations in three out of four subjects with fallopian tube cancer diagnosed in a two-year time span at our clinic. The mothers of two of these women suffered from breast or ovarian carcinoma. These results suggest on one hand that in patients with a history suggestive for a heredofamilial breast/ovarian cancer syndrome fallopian tube carcinoma is associated with high risk of BRCA2 mutation, and on the other hand that in patients/individuals with germline BRCA2 gene mutations in whom a prophylactic oophorectomy is performed, removal of fallopian tubes may be considered.

Primary fallopian tube carcinoma: the Queensland experience.

The purpose of this study was to review the experience with fallopian tube carcinoma in Queensland and to compare it with previously published data. Thirty-six patients with primary fallopian tube carcinoma treated at the Queensland Gynaecological Cancer Center from 1988 to 1999 were reviewed in a retrospective clinicopathologic study. All patients had primary surgery and 31/36 received chemotherapy postoperatively. Abnormal vaginal bleeding (15/36) and abdominal pain (14/36) were the most common presenting symptoms at the time of diagnosis. Median follow-up was 70.3 months and the median overall survival was 68.1 months. Surgical stage I disease (P = 0.02) and the absence of residual tumor after operation (P = 0.03) were the only factors associated with improved survival. Twenty of the 36 patients (55%) presented with stage I disease and survival was 62.7% at 5 years. No patient with postoperative residual tumor survived. The majority of the patients with fallopian tube carcinoma present with stage I disease at diagnosis, but their survival probability is low compared with that of other early stage gynecological malignancies. If primary surgical debulking cannot achieve macroscopic tumor clearence, the chance of survival is extremely low.

Dysplastic changes in prophylactically removed Fallopian tubes of women predisposed to developing ovarian cancer.

The aim of this study was to investigate the occurrence of (pre)neoplastic lesions in overtly normal Fallopian tubes from women predisposed to developing ovarian carcinoma. The presence of (pre)neoplastic lesions was scored in histological specimens from 12 women with a genetically determined predisposition for ovarian cancer, of whom seven tested positive for a germline BRCA1 mutation. A control group included 13 women. Immunohistochemistry was used to determine the expression of p21, p27, p53, cyclin A, cyclin D1, bcl-2, Ki67, HER-2/neu, and the oestrogen and progesterone receptors. Loss of heterozygosity (LOH) analysis on the BRCA1 locus was also assessed on dysplastic tissue by PCR studies. Of the 12 women with a predisposition for ovarian cancer, six showed dysplasia, including one case of severe dysplasia. Five harboured hyperplastic lesions and in one woman no histological aberrations were found in the Fallopian tube. No hyperplastic, dysplastic or neoplastic lesions were detected in the Fallopian tubes of control subjects. In the cases studied, morphologically normal tubal epithelium contained a higher proportion of Ki67-expressing cells (p=0.005) and lower fractions of cells expressing p21 (p<0.0001) and p27 (p=0.006) than in the control group. Even higher fractions of proliferating cells were found in dysplastic areas (p=0.07) and accumulation of p53 was observed in the severely dysplastic lesion. Expression patterns of other proteins studied, including the hormone receptors, were similar in cases and controls. One subject, a germline BRCA1 mutation carrier, showed loss of the wild-type BRCA1 allele in the severely dysplastic lesion. In conclusion, the Fallopian tubes of women predisposed to developing ovarian cancer frequently harbour dysplastic changes, accompanied by changes in cell-cycle and apoptosis-related proteins, indicating an increased risk of developing tubal cancer.

[Pelvic endoscopy in diagnosing fallopian tube disorders that cause infertility].

Over the period of 25 years, 1080 pelvic endoscopy in infertile women were performed, with special attention payed to the pathology of Fallopian tubes. Pelvic endoscopy was performed after previous HSG. During the pelvic endoscopy, the state of the uterus, ovaries and uterine tubes were evaluated, with much attention paid to the condition of the abdominal ostium of the uterine tube, symptoms of active and chronic inflammation, endometriosis, the authors also tried to diagnose the extension and character of pelvic-salpingian adhesions. Confrontation of the results enabled diagnosis in 111 (41.7%) women, out of 266, with patient Fallopian tubes the organic factors which impaired conception or made conception impossible. In the group of 814 women with tubal impotency in 15 (1.8%) cases extratubal factor was found, subserosal myoma in uterine horn, cyst, adhesions, while Fallopian tube itself was patent and unchanged. Organic factors of Fallopian tube disorder were determined. In 360 (44.2%) patients, out of 814, with tubal impotency pathological status was found (active salpingitis, tuberculosis, endometriosis) which required establishing of a necessary treatment and cancelling the surgical treatment.
