Comparison of Lerner score, Doppler ultrasound examination, and their combination for discrimination between benign and malignant adnexal masses.

OBJECTIVE: To determine whether the combined use of Lerner's morphologic score and color Doppler ultrasound examination results in better discrimination of benign and malignant adnexal masses than the use of Lerner's score alone or Doppler variables alone. DESIGN: One hundred and seventy-three consecutive women with a pelvic mass judged clinically to be of adnexal origin underwent preoperative ultrasound examination including color and spectral Doppler techniques. One hundred and forty-nine tumors were benign and 24 malignant. The sensitivity and false-positive rate with regard to malignancy were calculated for Lerner's score, six Doppler variables and combinations of Lerner's score and Doppler variables. Previously defined gray scale and Doppler criteria of malignancy were used and tested prospectively. The best method was defined as that detecting most malignancies with the lowest false-positive rate. RESULTS: Lerner's score had a sensitivity of 92% and a false-positive rate of 36%. The best Doppler variable--time-averaged maximum velocity--had similar diagnostic properties with a sensitivity of 100% and a false-positive rate of 41%. Combining Lerner's score with Doppler measurement of time-averaged maximum velocity--i.e. requiring both Lerner's score and time-averaged maximum velocity to indicate malignancy for a malignant diagnosis to be made--had a sensitivity of 92% and a false-positive rate of 19%. CONCLUSIONS: The combined use of Lerner's score and measurement of time-averaged maximum velocity is a better method for discrimination of benign and malignant adnexal masses than the use of Lerner's score alone or Doppler ultrasound examination alone. The clinical value of the combined method needs to be cross-validated prospectively in a new series of tumors.

Transvaginal color Doppler assessment of venous flow in adnexal masses.

OBJECTIVE: To analyze the usefulness of transvaginal color Doppler assessment of venous flow in the differential diagnosis of adnexal masses. MATERIAL AND METHODS: Ninety-one consecutive patients (mean age: 46.6 years, range: 16-81 years) diagnosed as having an adnexal mass were evaluated by transvaginal color Doppler sonography prior to surgery. Color Doppler was used to detect and analyze the flow velocity waveform from arterial and venous blood flow within the tumor. For arterial signals the resistance index and peak systolic velocity, and for veins the maximum venous flow velocity, were calculated. Receiver operator characteristic curves were plotted to determine the best venous flow velocity cut-off. According to our previous study using arterial Doppler, a tumor was considered as malignant when flow was detected and the lowest resistance index was < or = 0.45. Using venous Doppler a mass was considered as malignant when flow was detected and the venous flow velocity was > or = the best cut-off found on the receiver operator characteristic curve. Definitive histopathological diagnosis was obtained in all cases. Sensitivity, specificity, positive predictive value and negative predictive value for B-mode morphology (evaluation performed according to Sassone's scoring system), arterial Doppler, venous Doppler, and a combination of both arterial and venous Doppler were calculated. RESULTS: Twenty-five masses (27.5%) were malignant and 66 (72.5%) benign. Arterial and venous flow was found more frequently in malignant than in benign masses (92% vs. 41% (P < 0.001) and 72% vs. 21% (P < 0.001), respectively). The resistance index was significantly lower in malignant tumors (0.42 vs. 0.60, P = 0.0003). No differences were found in peak systolic velocity. Venous flow velocity was significantly higher in malignant masses (18.1 cm/s vs. 8.9 cm/s, P = 0.0006). The best cut-off of venous flow velocity was 10 cm/s. Sensitivity, specificity, positive predictive value and negative predictive value for morphology, arterial Doppler, venous Doppler, and the combination of both arterial and venous Doppler were 92%, 71%, 45%, 96%; 76%, 95%, 87%, 91%; 68%, 94%, 81%, 89%; and 88%, 91%, 79%, 95%, respectively. CONCLUSIONS: Our results indicate that preoperative evaluation by venous flow assessment of adnexal masses may be useful to discriminate between malignant and benign tumors.

The natural history of adnexal cysts incidentally detected at transvaginal ultrasound examination in postmenopausal women.

OBJECTIVE: To determine the natural history of adnexal cysts incidentally detected at transvaginal ultrasound examination and judged to be benign in postmenopausal women. METHODS: One hundred and thirty-four postmenopausal women referred for ultrasound examination and found to have an adnexal cyst judged to be benign and not causing any symptoms were followed with transvaginal ultrasound at 3, 6 and 12 months, and then every 12 months. The referring physician treated the patient at his/her own discretion. RESULTS: One hundred and sixty cysts were found, 121 (76%) being unilocular and 39 more complicated. Seventy-two cysts (45%) had a largest diameter of 3-19 mm and 88 (55%) had a largest diameter of 20-80 mm. Median follow-up time was 3 (range, 0.3-8) years. In twelve women (9%) the cysts were removed during follow-up, all their cysts (n = 14) being benign. The indication to operate was a change in cyst morphology or increased cyst size in five (4%) women. In 39 (29%) women, the cysts disappeared; in 18 (13%), new cysts developed; and, in 65 (49%), the number of cysts and their location remained unchanged. Regression of cysts was observed in 54% (33/61) of women < 60 years vs. in 8% (6/73) of those > or = 60 years (P = 0.0001). Ultrasound findings remained unchanged in 34% (21/61) of women < 60 years vs. in 77% (56/73) of those > or = 60 years (P = 0.0001). CONCLUSIONS: The results support conservative management of adnexal cysts incidentally detected at transvaginal ultrasound examination and judged to be benign in postmenopausal women. Whether such cysts need to be followed-up at all and, if they do, how often and for how long, remains an open question.

Can bowel endoscopy predict colorectal surgery in patients with an adnexal mass?

The objective of this retrospective study was to identify the ability of preoperative endoscopy of the lower gastrointestinal tract and other tests to predict large bowel resection in patients with an adnexal mass. We reviewed 573 patients with a suspected adnexal mass admitted for surgery between 1987 and 1997. Two hundred fifty four patients (44%) had preoperative sigmoidoscopy (n = 97) or colonoscopy (n = 157). We identified patients who underwent a colorectal operation as part of their surgery and correlated surgical findings with the results of preoperative endoscopy, preexisting clinical symptoms, preoperative pelvic exam and ultrasonography, and the CA125 level. The sensitivity and positive predictive value of bowel endoscopy for predicting large bowel surgery were 18% and 59%, respectively. Multivariate analysis showed preexisting bowel-related symptoms, a pelvic exam suggestive of malignancy, a CA125 value >1000 U/ml, and infiltration of the colorectal wall at bowel endoscopy to be independently associated with subsequent colorectal surgery. We conclude that preoperative bowel endoscopy cannot accurately predict colon resection in patients with a suspected adnexal mass. Preexisting bowel-related symptoms, a pelvic exam suggestive of malignancy and a CA125 value >1000 U/ml are associated with subsequent colorectal surgery.

Successful laparoscopic management of adnexal torsion during week 25 of a twin pregnancy.

Adnexal torsion is a rare occurrence during pregnancy. Here we present a case of adnexal torsion during the 25th week of pregnancy, which was managed laparoscopically. The woman had achieved a successful twin pregnancy after in-vitro fertilization/intracytoplasmic sperm injection. She was admitted to the emergency department with acute abdominal pain. Abdominal ultrasound with colour Doppler mapping of the intra-ovarian blood flow showed adnexal torsion. Laparoscopic management was successfully carried out.

A prospective randomized study of laparoscopy and minilaparotomy in the management of benign adnexal masses.

BACKGROUND: Recent prospective and randomized studies have demonstrated that laparoscopy is better than laparotomy in the treatment of benign adnexal masses. The aim of this study is to analyse the perioperative outcomes of laparoscopy and minilaparotomy in these patients, in a prospective and randomized manner. METHODS: Between January 2003 and August 2003, 100 consecutive women with a diagnosis of presumed benign adnexal mass and requiring surgical treatment were randomly assigned to minilaparotomy and laparoscopy. Randomization was centralized and computer-based. RESULTS: All operative procedures were performed without conversion to laparotomy. In the group of patients submitted to minilaparotomy, a shorter operating time than patients submitted to operative laparoscopy (mean+/-SD: 71.9+/-31.8 versus 87.0+/-44.8 min; P<0.05) was found. On the other hand, there were significant differences in terms of postoperative ileus (1.1+/-0.4 days in laparoscopy and 1.4+/-0.6 in minilaparotomy P<0.023), without affecting the day of discharge. No intraoperative or early complications were registered in either group. CONCLUSIONS: Taking into account that laparoscopy has to be considered the first choice for benign adnexal surgery, our data suggest that minilaparotomy could offer the gynaecology surgeon a valid alternative in the minimally invasive surgery field, especially in specific settings.

Treatment of adnexal torsion using operative laparoscopy.

The aim of this work was to clarify the value and application of operative laparoscopic treatment for adnexal torsion. We included in our study all patients (n = 27) who presented with an intra-operative diagnosis of torsion of the adnexa between January 1989 and May 1995. A total of 28 adnexal torsions were treated. Treatment was carried out by laparoscopic surgery in 75% of cases (21 torsions): in one-half of the cases (14 torsions) it was possible to achieve conservative laparoscopic treatment. The nature of the lesions and the experience of the surgeons are two factors which closely govern the outcome of surgical treatment. For those patients presenting a benign pathology, laparoscopic surgery was used to treat 84% of cases in the series. All the patients presenting a benign pathology and operated upon since 1993 have received laparoscopic surgical treatment. No major complications (peritonitis, thrombotic emboli, coagulation problems) were observed after conservative laparoscopic surgery. These results demonstrate that, provided the surgeons are sufficiently experienced, treatment by conservative laparoscopic surgery for adnexal torsion is both safe and reliable. In the years to come more work must be done to assess the vitality of the adnexa so that as many patients as possible can benefit from conservative treatment.

Laparoscopic management of adnexal masses: a gold standard?

PURPOSE OF REVIEW: To review recent literature on the laparoscopic management of adnexal masses, when this approach may be considered as a gold standard. RECENT FINDINGS: Cyst rupture was recently demonstrated to be a significant prognostic factor in stage I invasive epithelial carcinoma, and it was recommended to restrict the laparoscopic approach to patients with preoperative evidence that the cyst was benign. The laparoscopic approach is still highly controversial in masses suspicious at ultrasound. The limits of the laparoscopic approach are discussed reviewing recent literature and our experience. The laparoscopic management of adnexal masses appears to be safe in most hospitals even in developing countries. This approach is being used with increasing frequency in unusual indications such as newborns, children, adolescents and pregnant women. The learning curve for endoscopic surgery appears to be longer than expected. Many patients with benign adnexal masses, such as ovarian endometrioma, are still treated by laparotomy or with an inadequate endoscopic technique. Several studies have suggested that the stripping technique is a tissue-sparing procedure. SUMMARY: The laparoscopic puncture of malignant ovarian tumours confined to the ovaries is uncommon, and should be avoided whenever possible. The teaching of endoscopy is essential to promote adequate procedures performed according to the principles of microsurgery and to preserve postoperative ovarian physiology.

The case for laparoscopic management of the adnexal mass.

Careful patient selection criteria can be used to identify patients who are appropriate for management of an adnexal masses via operative laparoscopy. Proper intraoperative assessment and liberal use of rapid frozen section are also important for optimal clinical outcome. Reported studies show that laparoscopic management of adnexal masses can be safely done. The short hospital stay and rapid return to normal activity combine to potentially reduce the overall cost of patient care. When cancer is unexpectedly found at the time of laparoscopic surgery for an adnexal mass, the surgeon should be prepared to proceed with staging laparotomy for appropriate treatment.

Adnexal masses in infancy and childhood.

The presentation of adnexal masses in childhood differs from that in adult women. Children may present with poorly localized symptoms or precocious puberty. Ovarian cysts occur throughout development; ovarian tumors are less frequent but occur in all age groups. Congenital malformations may present with signs or symptoms of an adnexal mass. Occasionally adnexal findings may suggest the presence of an underlying syndrome. Assessment of the patient's developmental, hormonal, and pubertal status is necessary to ensure an accurate diagnosis. Treatment options must consider risks to ovarian function and future fertility.

Ovarian function, reproduction, and later operations following adnexal surgery.

Among 3102 patients who had major gynecologic operations, only 223 (7.18%) needed adnexal operations during which reproductive potential was preserved. Operations involved ovaries (156), tubes (55), and embryologic cysts (32). After recovery 53.69% of these patients had viable babies (64.46% of patients under age 30). Patients were examined up to 28 years after operations, an average 11.32 years. When last examined. most patients still retained physiologic evidence of ovarian hormonal function; 20 patients had passed through spontaneous menopause, at an average age of 49.4 years. Fifty-two patients needed subsequent pelvic operations, but only 7 for possibly related conditions (4 repeat tubal pregnancies and 3 cyst-adenomas). All but one twisted adnexal mass, with gangrene, originated as a paramesonephric duct cyst. Seventeen adnexal operations were associated with pregnancy: 15 mothers had healthy babies, and 2 aborted. Details concerning numbers and characteristics of specific lesions are included in the paper.

Laparoscopic management of adnexal cystic masses in postmenopausal women.

OBJECTIVE: To evaluate laparoscopic treatment of postmenopausal women with an adnexal cystic mass predicted to be benign. METHODS: Selection criteria were transvaginal sonographic appearance other than a complex cyst and a normal serum CA 125 level. During the period May 1988 to June 1993, 55 women fulfilled the criteria and underwent operative laparoscopy. During the same period, 75 postmenopausal women underwent exploratory laparotomy for an adnexal cystic mass that was complex in appearance or associated with elevated serum CA 125. RESULTS: Laparoscopic bilateral oophorectomy was performed in all 55 women. All had benign masses (positive predictive value 100%). Malignant tumors were found in 23 of the 75 women undergoing laparotomy (negative predictive value 30.7%). There was no significant difference in size of the tumors between women undergoing laparoscopy or laparotomy. CONCLUSION: Because of its safety and efficacy, laparoscopic management is the preferred procedure in postmenopausal women with a non-complex adnexal mass and a normal CA 125 level.

Early diagnosis and predictors of malignancy of adnexal masses.

PURPOSE OF REVIEW: Ovarian cancer is an important cause of death among women with a malignant gynecological tumor. Cure rates for the disease at an early stage are around 80-90%, but survival is only 50% as the majority of women already show advanced disease upon diagnosis. The combination of gynecological examination, ultrasonography, and systemic tumor marker assay is considered to be a good strategy for the early diagnosis of ovarian neoplasia. RECENT FINDINGS: Today, new technologies such as ultrasonography and tumor marker assay have increased the diagnosis rate for adnexal masses. These non-invasive methods, however, frequently do not distinguish benign conditions from malignant ones, which results in unnecessary surgery. Transvaginal ultrasonography is useful for diagnosing adnexal masses, but benign and malignant adnexal masses can present similar morphological characteristics. Combination with color Doppler ultrasonography and/or tumor markers may improve the accuracy of the method. Gene-expression array, proteomics and mathematical models form new approaches, but proper prospective studies are needed to validate them. SUMMARY: The techniques of pelvic examination, ultrasonography, color Doppler ultrasonography, and tumor markers can be indicated for the diagnosis of ovarian cancer. The differentiation between benign and malignant ovarian tumor is, however, a clinical challenge. Until better diagnostic methods become available, patients and their physicians can use these techniques to decide on management.

Malignant transformation within benign adnexal skin tumours.

AIMS: To report five malignant trichogenic tumours arising in longstanding, previously benign adnexal neoplasms through malignant transformation. Malignant trichogenic adnexal tumours are extremely rare neoplasms. METHODS AND RESULTS: The patients were between 55 years and 79 years of age. Three of the tumours were located on the arms, two on the face. Three of our patients had a history of chronic lymphocytic leukaemia, one patient had a history of colonic adenocarcinoma. The duration of the tumour nodules was reported as between 20 and 40 years before sudden changes occurred. These changes included rapid growth, pain, itching, ulceration and bleeding. Histologically, all tumours were well circumscribed and encapsulated. There was a residual benign tumour component and morphological signs such as bone formation, dystrophic calcification and sclerosis suggesting long duration of the lesions. All patients except for one, who refused further clinical investigation due to her advanced age of 79 years, had an underlying systemic malignancy. CONCLUSIONS: The growth stimulus in these benign adnexal neoplasms resulting in malignant transformation may be attributed to the acquisition of additional genetic events or to immunosuppression due to an underlying neoplastic disease. Therefore, patients with systemic diseases or malignancy should be carefully examined and followed for sudden changes in pre-existing benign cutaneous tumours.

Skin adnexal neoplasms--part 2: an approach to tumours of cutaneous sweat glands.

Tumours of cutaneous sweat glands are uncommon, with a wide histological spectrum, complex classification and many different terms often used to describe the same tumour. Furthermore, many eccrine/apocrine lesions coexist within hamartomas or within lesions with composite/mixed differentiation. In addition to the eccrine and apocrine glands, two other skin sweat glands have recently been described: the apoeccrine and the mammary-like glands of the anogenital area. In this review (the second of two articles on skin adnexal neoplasms), common as well as important benign and malignant lesions of cutaneous sweat glands are described, and a summary for differentiating primary adnexal neoplasms from metastatic carcinoma is outlined, striving to maintain a common and acceptable terminology in this complex subject. Composite/mixed adnexal tumours are also discussed briefly.

Kinetics of a US contrast agent in benign and malignant adnexal tumors.

PURPOSE: To evaluate the effects of a microbubble contrast agent on the power Doppler ultrasonographic (US) examination of adnexal tumors, with a special focus on the timing of the transit of the microbubble bolus. MATERIALS AND METHODS: Seventy patients who were suspected of having ovarian tumors were examined preoperatively with contrast material-enhanced US. Images obtained during a 5-minute examination were stored digitally, and the behavior of the contrast agent was evaluated objectively with measurement of the time-dependent image intensity at the region of interest with a computer program. A time-intensity curve in each case was derived and analyzed. The Mann-Whitney U test was used to compare intensity changes and tumor parameters in benign and malignant adnexal tumors. RESULTS: Both the baseline and maximum power Doppler intensities, as well as the absolute and relative (percent) rise in intensity, were significantly higher (P <.001) in malignant as compared with benign tumors. The arrival time was shorter (17.5 vs 22.5 seconds; P =.005) and the duration of contrast agent effect was longer (190.4 vs 103.6 seconds; P <.001) in malignant tumors than they were in benign tumors. The area under the time-intensity curve was significantly greater in malignant tumors compared with that in benign tumors (P <.001). CONCLUSION: After microbubble contrast agent injection, malignant and benign adnexal lesions behave differently in degree, onset, and duration of Doppler US enhancement.

Adnexal and cul-de-sac abnormalities: transvaginal sonography.

Sixty-seven patients selectively chosen from 354 undergoing conventional transabdominal (TA) sonography for evaluation of a clinically suspected adnexal mass subsequently underwent transvaginal (TV) sonography either because the TA sonograms were technically suboptimal or because it was not possible to characterize with certainty an abnormality identified with TA sonography. TV sonography added diagnostically useful information in 25 of 28 patients with cystic pathologic changes in the adnexa uteri. Eight of 12 patients with tuboovarian abscess and nonspecific adnexal masses visualized with TA sonography had tube-shaped fluid collections characteristic of pyosalpinx identified with TV sonography. TV sonography added diagnostically useful information in all seven patients with diseases of the cul-de-sac (rectouterine fossa) and allowed differentiation of adnexal from primary uterine disease in three patients with TA sonograms on which findings were equivocal. It also expedited the diagnosis of a tubal pregnancy in ten of 14 patients and was useful in the detection of adhesions and perforated intrauterine devices. These results indicate that adjunctive TV sonography can provide important diagnostic information.

Adnexal masses: transvaginal US and gadolinium-enhanced MR imaging assessment of intratumoral structure.

PURPOSE: To evaluate the accuracy of transvaginal ultrasound (US) and gadolinium-enhanced magnetic resonance (MR) imaging in the assessment of the intratumoral structure of an adnexal mass. MATERIALS AND METHODS: The population comprised 82 patients with an adnexal mass who underwent both transvaginal US and gadolinium-enhanced MR imaging and had surgical confirmation. The findings from both modalities were compared retrospectively with those of surgery. RESULTS: The sensitivity, specificity, and accuracy were 100%, 98%, and 99% with MR imaging and were 97%, 46%, and 68% with transvaginal US for the identification of solid tissue in the masses. Transvaginal US exhibited many (n = 25) false-positive results, especially in evaluation of lesions filled with blood or fatty tissue and small echogenic excrescences adherent to the wall, such as blood or fatty tissue. CONCLUSION: Both transvaginal US and gadolinium-enhanced MR imaging were highly sensitive in identification of solid components within an adnexal mass. Gadolinium-enhanced MR imaging was specific, whereas transvaginal US was nonspecific.
