Site of origin of epithelial ovarian cancer: the endometriosis connection.

To investigate the left- and right-sided distribution of ovarian malignant surface epithelial tumours, data were collected on 209 women undergoing first-line surgery for Stage I and II disease. Considering the unilateral cancers, the observed proportion of left-sided lesions was 35/54 (65%) in the endometrioid, 20/45 (44%) in the serous, 19/35 (54%) in the clear cell, 13/29 (45%) in the mucinous, 2/8 (25%) in the mixed, and 2/5 (40%) in the undifferentiated histological type group. The proportion of left-sided unilateral endometrioid cancers was significantly different from the expected 50% (chi2(1), 4.74, P = 0.03) and very similar to that previously observed for benign endometriotic cysts, constituting further evidence in favour of a possible development of endometrioid cancers from the latter lesions.

Endometrial ability to implant in ectopic sites can be prevented by interleukin-12 in a murine model of endometriosis.

Immune dysfunctions in endometriosis are widely documented but the effectiveness of immunotherapies for the management of the disease is still debated. Progress in this field has also been limited by the lack of an appropriate animal model of the disease. In this study, we created a model of endometriosis in immunocompetent mice to verify the ability of endometrium to implant in ectopic sites and to investigate the potential application of the cytokine interleukin (IL)-12 in preventing this ectopic implantation. Endometriotic lesions were induced in both C57BL/6 and BALB/c mice by inoculating syngenic endometrial fragments through a small laparotomic incision into the peritoneal space. All the animals challenged with syngenic endometrium showed evidence of peritoneal endometriosis at 3 weeks. Histologically, endometriotic lesions consisted of cystic endometrial glands surrounded by a stroma. Intraperitoneal injection of IL-12 was able to reduce total weight and total surface area of endometriotic lesions respectively of 77 and 61% in C57BL/6 and of 42 and 28% in BALB/c mice. These results demonstrate that IL-12 is able to induce a significant prevention of ectopic endometrial implantation in an in-vivo model of endometriosis. These findings support the possibility of using the immune system to generate novel therapies for the management of the disease.

Endometrial morphology and ultrasound vascular findings. A randomized trial after intramuscular and vaginal progesterone supplementation in IVF.

Luteal-phase supplementation has proved necessary in Gn-RH analog and human gonadotropin-stimulated cycles. We studied the effects of vaginally and intramuscularly delivered progesterone on the endometrium. Thirty patients enrolled in an IVF program without embryo transfer due to absence of fertilization were included in the study. Patients were randomly allocated to two treatment groups. Group A (n = 15) was administered 200 mg progesterone b.i.d. by the vaginal route (Esolut, Angelini) starting on the day of oocyte pick up and group B (n = 15) was given 100 mg intramuscular progesterone once daily (Prontogest, Amsa). Six days after HCG administration, biopsies were obtained for endometrial histological maturation and estrogen (ER) and progesterone (PR) receptor analyses. In addition, ultrasound measurements of endometrial thickness were made and uterine and myometrial artery flow was determined. Serum concentrations of estriol and progesterone were measured on the day of HCG, at oocyte pick up and at endometrial biopsy. The two treatment groups were similar in terms of follicular phase parameters during superovulation with Gn-RH analog and gonadotropin. Histologic, receptor and ultrasonographic analyses showed no significant differences between the two treatment groups. Our results indicate that both intramuscular and vaginal progesterone are equally effective on the endometrium.

Sclerosing stromal tumor of the ovary. Report of eight cases and review of the literature.

In this article, we describe eight cases of sclerosing stromal tumors (SST) of the ovary and review the literature. We could not demonstrate unequivocal hormonal activity in any of the cases, although suggestive evidence for it has been reported in the literature in the form of clinical, histologic, electron microscopic and immunohistochemical findings.

Endometrial ablation with a vaporizing electrode. I. Evaluation of in vivo effects.

BACKGROUND: To evaluate histologically and histochemically the physical and thermal effects of a vaporizing electrode as compared with a standard cutting loop in the performance of endometrial ablation. METHODS: Operative hysteroscopy was performed on 20 menorrhagic patients immediately before hysterectomy. Part of the posterior uterine wall was treated with a cylindrical, grooved, vaporizing electrode and undamped current set at 200 watts, and part with a standard cutting loop and undamped current set at 100 watts. A mucosal strip of about 1 cm width was left intact between the two treatment areas. Specimens underwent histologic examination after hematoxylin and eosin staining and histochemical assessment of thermal injury was based on detection of the respiratory enzyme dihydronicotinamide adenine dinucleotide diaphorase. RESULTS: The mean (standard deviation) endometrial thickness as determined on the untreated area of the posterior uterine wall was 1.08 (0.36) mm. The mean depth of furrows was 3.10 (0.90) mm with the use of the vaporizing electrode and 3.41 (1.11) mm after passage of the cutting loop. Corresponding values when thermal necrosis beneath the ablated area was assessed by the dihydronicotinamide adenine dinucleotide diaphorase technique were, respectively, 1.80 (0.40) mm and 0.41 (0.20) mm (mean difference, 1.39 mm; 95% confidence interval, 1.19 to 1.59: p<0.001, Mann-Whitney U test). CONCLUSIONS: A vaporizing electrode and a standard cutting loop obtained a similar degree of endomyometrial ablation. However, the depth of the thermal effect of the former electrode was significantly greater. Clinical studies are warranted, also considering the potential limitation of fluid absorption and menorrhagia recurrence when a vaporizing electrode is used.

Is cystic ovarian endometriosis an asymmetric disease?

OBJECTIVE: To investigate whether asymmetry exists in the left- and right-handed distribution of ovarian cystic lesions in a large series of women with endometriosis. DESIGN: Retrospective evaluation of a case series. SETTING: Tertiary care and referral academic centre for the study and treatment of endometriosis. POPULATION: A total of 1054 consecutive women undergoing first-line surgical treatment for endometriosis in an eight-year period. METHODS: Data were collected on indication for the intervention, age at surgery, parity and disease stage as well as side and size of ovarian endometriomas. MAIN OUTCOME MEASURE: Frequency of left- and right-sided ovarian endometriomas. RESULTS: Histologically confirmed endometriotic ovarian cysts were present in 561 women, which were on the left side in 255 instances, on the right in 148, and bilateral in 158. In the patients with unilateral endometriomas, the observed proportion of left cysts (255/403, 63%; 95% confidence interval, 58% to 68%) was significantly different from the expected proportion of 50%, (chi2(1), 28.41, P<0.001). Including also the bilateral endometriotic cysts gave a total of 413/719 (57%) left-sided and 306/719 right-sided endometriomas. The magnitude of these proportions did not vary appreciably during the eight years considered. The difference in proportion of left- and right-sided endometriotic cysts was virtually similar in subgroups of women with different indications for surgery. Cyst side was not related to age, parity or cyst diameter. CONCLUSIONS: The finding of a lateral asymmetry in the occurrence of ovarian endometriotic cysts is compatible with the anatomical differences of the left and right hemipelvis and supports the menstrual reflux theory.

Endometriosis and ovarian cancer.

In 556 patients undergoing surgery for ovarian cancers the frequency of endometriosis ranged from 3.6% to 5.6% in serous, mucinous, and miscellaneous neoplasms versus 26.3%, 21.1%, and 22.2%, respectively, in endometrioid, clear cell, and mixed subtypes; the differences were statistically significant (chi 2 heterogeneity 50.0, p < 0.001) and consistent in strata of age, parity, menopausal status, and disease stage.

Serous borderline tumors of the ovary. A clinicopathologic, immunohistochemical, and quantitative study of 44 cases.

The clinicopathologic features of 44 serous borderline tumors (SBT) of the ovary were evaluated. Nineteen were Stages II and III, and 9 had invasive peritoneal implants. All 19 patients received chemotherapy and 4, who had invasive implants, died of disease after 3, 4.3, 8, and 9 years. The other 25 patients were free of tumor 1-14 years (mean, 5.3 years) after surgery. Coexpression of low molecular weight keratins (AE1, CAM 5.2) and vimentin was found in all tumors and their implants. No significant differences were found between SBT with different volume-corrected mitotic indices (M/Vi) with respect to gross features, presence or absence of implants, stage, and survival. Cytometric DNA analysis also was performed on the primary ovarian tumors and the implants. Twenty-one primary tumors had diploid or tetraploid histograms, and 23 had aneuploid histograms. DNA ploidy of the primary ovarian tumors did not correlate with gross features, the presence or absence of implants, M/Vi, stage, and survival. The data from this study confirm that most SBT are clinically benign, but SBT with invasive implants may behave aggressively. Expression of intermediate filaments, M/Vi, and DNA ploidy evaluation of the primary ovarian tumors seem to be of no value in predicting prognosis. However, four of seven patients with aneuploid DNA implants died of tumor.

Transvaginal ultrasonography in the differential diagnosis of adenomyoma versus leiomyoma.

OBJECTIVE: We evaluated the reliability of transvaginal ultrasonography in the differential diagnosis of adenomyoma versus leiomyoma. STUDY DESIGN: Preoperative transvaginal ultrasonographic results were compared with postoperative pathologic findings in 405 women who underwent surgery for symptomatic uterine nodularity. RESULTS: For adenomyoma diagnosis, transvaginal ultrasonography demonstrated a sensitivity of 87%, a specificity of 98%, a positive predictive value of 74.1%, and a negative predictive value of 98.6%, compared with a sensitivity of 96.1%, a specificity of 83.3%, a positive predictive value of 98.4%, and negative predictive value of 35.7% for leiomyoma diagnosis. CONCLUSION: Transvaginal ultrasonography is an effective, noninvasive, and relatively inexpensive procedure for the preoperative differential diagnosis of adenomyoma versus leiomyoma.

Transvaginal ultrasonography in the diagnosis of diffuse adenomyosis.

OBJECTIVE: To evaluate the diagnostic capability of transvaginal ultrasonography in detecting diffuse adenomyosis. DESIGN: We compared the preoperative transvaginal ultrasound (US) findings and the pathological findings of the surgical specimen in a series of women who underwent hysterectomy for menorrhagia. PATIENTS: Forty-three women (mean [+/- SD] age of 46 +/- 5) with recurrent menorrhagia and enlarged uterus, without evidence of uterine leiomyomas at abdominal US and of endometrial disease at vabra curettage. SETTING: Tertiary care center, university medical school. MAIN OUTCOME MEASURES: Sensitivity, specificity, predictive positive and negative values of transvaginal US in the diagnosis of diffuse adenomyosis. RESULTS: The sonographer diagnosed adenomyosis in 22 patients, whereas the pathologist found adenomyosis in 20 women, confirming the US findings in 16 cases and making an ex novo diagnosis in 4. The sensitivity of transvaginal US was 80%, the specificity 74%, the predictive value of a normal test 81%, and that of an abnormal test 73%. CONCLUSIONS: Transvaginal US seems to represent a real advance in the preoperative diagnosis of diffuse adenomyosis.

Inguinal endometriosis: pathogenetic and clinical implications.

In six women with a preoperative diagnosis of incarcerated hernia, surgical exploration of the groin revealed inguinal endometriosis and no hernia. The affected structure was always the extraperitoneal portion of the round ligament. Six of the seven lesions were on the right. Intraperitoneal endometriosis was demonstrated in all patients. Catamenial pain was the pathognomonic symptom in the differential diagnosis of the inguinal mass. Gynecologists and surgeons should bear in mind the possibility that endometriosis may be the cause of symptoms of a suspected incarcerated inguinal hernia. Should this disease be detected at inguinal exploration, a laparoscopy is indicated during the same operation.

Endometrium of cavitary rudimentary horns in unicornuate uteri.

The rudimentary horns removed from ten patients with unicornuate uterus, subclass A1b, were studied by light and scanning electron microscopy. Seven of the horns removed were small in volume (range 7.5-15.7 mL) and three were larger (range 20.8-39.7 mL). In four cases the endometrial cavity communicated with the tubal lumen, hematometra was present in three cases, and endometriosis was diagnosed in six. In six of the seven rudimentary horns without hematometra, the endometrial mucosa did not correspond to the cycle phase of the endometrium of the hemiuterus; however, in the three rudimentary horns with hematometra, the endometrium presented cycle-phase characteristics similar to those of the hemiuterus. The endometrio-myometrial junction, the underlying myometrium, and the arcuate arterioles were always altered. We consider that the absence of cyclic changes in the endometria of the smaller horns may be attributed to reduced vascular supply, to the absence of any isthmocervical structure, and to the qualitative and/or quantitative differences in endometrial mucosal receptors.

ICRF 159 plus radiation versus radiation therapy alone in cervical carcinoma. A double-blind study.

In a double-blind trial the effect of ICRF 159 or placebo associated with radiotherapy was compared in 70 patients with cervical carcinoma. No significant differences were found on histopathological examination of surgical specimens obtained 6 weeks after the end of the treatment. Clinical evaluation after a follow-up of 46 +/- 5 months, also showed no significant effect of ICRF 159 with radiotherapy.

Natural history of dysgerminoma.

Data on 56 patients with pure dysgerminoma are discussed. Forty-nine patients were classified as having new disease or were to have reassessment of disease, and seven cases were to be restaged (one with and six without clinical evidence of disease). Of new and reassessment cases, 44 patients underwent lymphography, 16 underwent peritoneoscopy with diaphragmatic inspection and 30 had peritoneal cytologic testing performed. Positive lymphography resulted in restaging in 31.6% of patients. Diaphragmatic inspection was always negative. Peritoneal cytologic testing was positive for malignant cells in three patients and worsened the stage in one. Pathologic staging of disease was as follows: Stage IA, 24; Stage IB, one Stage IC, one; Stage III peritoneal disease, two. Stage III retroperitoneal disease, 12; Stage III peritoneal and retroperitoneal disease; four. The 5-year relapse-free survival rates were 91% in patients with pathologic Stages IA, IB, and IC; 74% in those with Stage III retroperitoneal disease, and 24% in patients with Stage III peritoneal disease or peritoneal plus retroperitoneal disease. The results indicate that the prognosis is excellent for patients with Stage I and Stage III retroperitoneal disease whereas peritoneal involvement is associated with a poor prognosis.

Significance of ascitic fluid and peritoneal washing cytology in ovarian tumor diagnosis.

The results of the cytological test on 179 ascitic fluids and 88 peritoneal washes of patients suspected to have ovarian tumors are critically reviewed to illustrate the difficulties, limitations and future possibilities of this technique. Tissue correlation was available in all cases. The data was evaluated in order to obtain information as to the accuracy, sensitivity and specificity of cytological examination, both in ascitic fluids and in peritoneal washings. A correct diagnosis as to the ovarian tumor histotype was obtained in more than 80 per cent of the cases.

Effect of a new oral antiandrogen-estrogen combination on the endometrium: histological and ultrastructural scanning electron microscopy study.

Endometrial biopsies were obtained in 12 volunteers between 18 and 35 years old who had used SHB 209 AE oral contraceptive during the previous six months. Three main types of endometrial patterns were observed: proliferative, very similar to a normal proliferative phase; early secretory: similar to early postovulatory endometrium; late secretory: characterized by diffuse predecidual changes in the stroma. At SEM after one week a great prevalence of nonciliated cells was observed. During the 2nd and the 3rd week, the endometrial surface appears still flattened with scanty glandular outlets.
