Ovarian cancer screening.

Abstract: Background. The three most extensively evaluated screening methods for ovarian cancer are pelvic examination, serum CA 125, and transvaginal sonography (TVS). The lack of sensitivity of pelvic examination and serum CA 125 has limited their use in ovarian cancer screening. Currently, the most effective screening method for ovarian cancer is TVS. Methods. Transvaginal sonography was performed with a standard ultrasound unit and a 5.0 MHz vaginal transducer. Each ovary was measured in three dimensions and ovarian volume was calculated using the prolate ellipsoid formula (L X H X W X 0.523). An ovarian volume greater than or equal to 20 cm 3 in premenopausal women and greater than or equal to 10 cm 3 in postmenopausal women was considered abnormal. Also, any internal papillary projection from the tumor wall was considered abnormal. A patient with an abnormal screen had a repeat TVS in 4-6 weeks. Women with a persisting abnormality on TVS underwent pelvic examination, serum CA 125 determination, Doppler flow sonography, and tumor morphologic indexing before operative tumor removal. Results. Eighty-five hundred asymptomatic women underwent TVS screening. One hundred twenty-one of these women had a persisting abnormality and underwent tumor removal. Fifty-seven patients had serous cystadenomas and eight had primary ovarian cancers. Six patients had Stage IA ovarian cancer, one had Stage IIC ovarian cancer, and one had Stage IIIB ovarian cancer. Only one of these patients had palpable ovarian enlargement on clinical examination and one had an elevated serum CA 125. All patients are alive and well 4-61 months after conventional therapy. The direct cost of TVS screening was highest during the initial years of the program and fell progressively to $30/screen during the 4th year of the study. Worldwide, more than 14,000 women have been screened using ultrasonography, and 19 ovarian cancers have been detected. More than 20,000 patient-screening-years have been accrued, and there have been no deaths from primary ovarian cancer in the screened population. Conclusions. Transvaginal sonography screening causes a decrease in stage at detection and a decrease in case-specific mortality. Further study is needed to determine if annual TVS screening will significantly reduce ovarian cancer mortality. The cost for TVS screening is reasonable and is well within the range of that reported for other screening tests.

Evaluation of ovarian findings in asymptomatic postmenopausal women with color doppler ultrasound

Abstract: Background. To evaluate the prevalence and significance of abnormal ovarian findings in asymptomatic postmenopausal women, screening for ovarian cancer with color Doppler ultrasound was performed. Methods. One thousand three hundred sixty-four asymptomatic women aged 56-61 years (mean, 59 years) were examined by color Doppler sonography. Ninety-six percent of the examinations were transvaginal and 4% transabdominal. The criteria for abnormality were an ovarian volume 8 cm3 or greater, nonuniform echogenicity, and/or pulsatility index (PI) of the ovarian artery or tumor vessel, if present, 1.0 or less. Repeat sonograms were performed 1-3 months later on all patients with abnormal findings, and exploratory laparotomy was performed if a malignant tumor was suspected. Results. Abnormal ovarian findings were detected in 160 women (12%). At the time of repeat sonogram there were 28 persisting abnormalities (2%). At that time, the ovary was regarded as normal if it still contained a small clear cyst with an unchanged greatest dimension of less than 20 mm. Three women had a low PI value but all had also abnormal ovarian sonographic morphology. Two ultrasound-guided cyst punctures were performed and three patients had surgery; one benign serous cyst, one benign serous cystadenoma, and one serous cystadenoma of borderline malignancy were detected. The remaining abnormal findings disappeared or remained unchanged during a minimum follow-up of 2 years. One case of Stage IA ovarian cancer has been reported 2 years after a negative screening and one abdominal carcinomatosis 2% years after a negative screening result. Conclusions. There is a high frequency of small ovarian cysts in asymptomatic postmenopausal women. A large percentage of these cysts regress spontaneously or

Laparoscopic preliminary surgery of ovarian malignancies. Experiences from 127 German gynecologic clinics

Abstract: A controversial discussion has arisen between endoscopists and oncologists about laparoscopic management of ovarian cancer and borderline tumours. A questionnaire was mailed to 273 German Departments of Gyn./Obst. A response rate of 46% (127 hospitals) was obtained concerning the endoscopical technique used, the kind and delay of post-endoscopical cancer operation and the early findings (follow-up) in cases of ovarian cancer, dysgerminoma, malignant teratoma, tubal cancer and borderline tumours of the ovary. In this German survey it could be shown that laparoscopic management of malignant ovarian tumours was not uncommon between 1991-1994. Totally, 61% of ovarian cancer stage Ia and 84 % of ovarian borderline tumours stage Ia have been reported without any pathological finding in laparotomy subsequent to laparoscopic management of the lesions. The 192 cases cited here are undoubtedly an underestimate of the real present frequency of endoscopically managed ovarian malignancies. Patients with this early negative report should be followed up carefully and may not permit conclusions that laparoscopic management of ovarian malignancies may be harmless for them. In 16% of the stage Ia borderline tumours and in 39% of the stage Ia ovarian cancer early spread has been found totally, demonstrating that implantations and metastases subsequent to the endoscopical procedure can be found even in an early follow-up phase. In 92.4 % laparoscopic capsule rupture, tumour morcellement with intraabdominal spilling, subsequent cystectomy or adnectomy had been the technique of choice with additional rinsing of the intraabdominal cavity. This was harmful for the majority of patients if the subsequent cancer surgery by laparotomy was delayed for more than 8 days. Early progression of these cases to stage I c has been reported in 20 % (7/36 cases) and to stage II-III in 53 % (19/36 cases). Only in 7.4% the endobag procedure was used in laparoscopic management of ovarian cancer stage Ia. In ovarian cancer stage Ic-III (n = 50) an early seeding in the laparoscopic tract was reported in 52% (13/25) if subsequent cancer surgery by laparotomy was delayed more than 8 days. The endoscopical techniques and the early findings after an endoscopical management are reported in detail. In conclusion, in respect of common oncological standards the actual practice in laparoscopic management of ovarian malignancy is considered poor surgery. Capsule rupture, tumour morcellement and unprotected biopsy in the intraabdominal cavity and an additional delay of adequate cancer surgery are the main pitfalls of that procedure. For the overwhelming majority of patients undergoing such endoscopical procedures very early implants and metastases in the pelvis, the abdominal cavity or the laparoscopic tract have been found. It seems necessary that laparoscopic management of ovarian malignancies and borderline tumours under the present technical conditions are given up and that we should return to reliable standards of oncological surgery comparable to laparotomy. This should be discussed urgently.

Endoscopic management of adnexal masses.

Abstract: Background The laparoscopic management of suspicious adnexal masses and early ovarian malignancies is discussed with the aim of maintaining accepted oncologic treatment principles. Comparative survival data of patients with gynecological malignancies managed by laparoscopy or laparotomy are still very scarce and the survival of cancer patients must not be compromised by new techniques. It is time to closely analyze laparoscopy and determine if it has a positive impact on the diagnosis and treatment of ovarian malignancies. In this paper we will address the following points: 1) Which ovarian cysts can be surgically treated by laparoscopy (pelviscopy)? 2) Is staging laparoscopy an accepted technique? 3) Is laparoscopy, as a second-look procedure, of benefit? 4) Is laparoscopic staging, together with histologic tissue sampling, adequate surgical technique in inoperable ovarian cancer with ascites and peritoneal carcinomatosis? 5) Does endoscopic biopsy of ovarian cancer stage Ia change the destiny of a patient into ovarian cancer Ic? Data base The above questions are analyzed based on our experience with the laparoscopic treatment of 1,225 patients with ovarian cysts and 165 ovarian cancer patients stage I to IV treated immediately by laparotomy during the years 1992-1995. Conclusions Ovarian cystic tumors with no signs of malignancy can be dealt with by laparoscopic means with the option of immediate conversion to laparotomy or within one week if an ovarian malignancy is diagnosed. Today sampling laparoscopic lymphadenectomy of both pelvic and para-aortic is feasible and adequate. On a curative level, the number of lymph nodes to be resected has yet to be determined. The adnexa can be extracted from the abdominal cavity with bag extraction without the danger of spillage. The uterus can be removed transvaginally with laparoscopic assisted vaginal hysterectomy (LAVH). We must be cautious to advocate laparoscopy for ovarian cancer. However, it is an excellent tool when used as a staging procedure. A careful preoperative screening of the patient and an exact definition of existing cysts with imaging techniques allows us to frequently apply laparoscopic surgery for ovarian cysts, leaving only readily detectable cancer cases for laparotomy. Many gynecological oncologists employing staging and second-look procedures for ovarian cancer agree that initiating a case with laparoscopy may preclude laparotomy for many patients. Tumor propagation by performing a biopsy in FIGO stage Ia ovarian cancer patients does not occur if the patient receives adequate radical surgical treatment within one week. According to the reports of Sevelda et al. and Dembo et al., the degree of differentiation and the existence of ascites are more relevant to decreasing the five-year survival rate of patients with ovarian cancer stage I than the rupture of capsule or penetration of the tumor. A dependency on the first two parameters was found in these two large statistical studies. As the question of endoscopic operations for adnexal mass is predominantly put for the sanitation of small ovarian tumors (ovarian tumors with solid particles in the cysts can be put into the section of primary laparotomies) there remains a wide field of indications for the laparoscopic treatment of adnexal mass and ovarian cysts with benign indications. For many young patients with non-malignant ovarian lesions such as endometriosis, benign cysts, benign cystic proliferations and fibromas, a laparotomy can be avoided and these lesions treated by laparoscopy.
