Invasive cervical cancer in pregnancy.

Detection of invasive cervical cancer during pregnancy is rare, with reported incidence rates ranging from 0.05% to 0.1%. However, cervical cancer is one of the most common malignancies diagnosed during pregnancy. The management of invasive cervical cancer in pregnancy is extremely challenging and requires a multidisciplinary team approach to optimise the treatment for the patient by simultaneously providing the best chance of survival for the foetus. The approach is based mainly on the following factors: gestational age at the time of the diagnosis, stage, histological subtype, desire regarding fertility and quality of life. The gold standard treatment for this condition in pregnancy is not yet established. This is due to the absence of prospective studies and clinical trials. Therefore, its management presents a dilemma that requires individualisation of care. The various factors that need to be considered for obtaining a good outcome for both mother and child are described in this study.

Ovarian recurrence from a Stage 1b1 cervical adenocarcinoma previously treated with radical vaginal trachelectomy: A case report.

► Post cervical cancer treatment new pelvic abnormality must be regarded as recurrence. ► Benign MRI features does not exclude recurrence from previous cervical adenocarcinoma.

Obstructive uropathy secondary to parametrial metastasis: an unusual presentation of breast carcinoma.

BACKGROUND: Metastasis to the cervix and parametrium from breast carcinoma is a rare occurrence. CASE REPORT: A 74-year-old woman presented to the urologists with loin pain and microscopic haematuria. Investigations revealed a right ureteric obstruction which was diagnosed to be secondary to parametrial metastasis from an unknown primary. Immunohistochemical studies revealed it to be originating from the breast. Occult breast carcinoma was then diagnosed by breast biopsy. CONCLUSION: Obstructive uropathy secondary to parametrial metastasis is an unusual first presentation of breast carcinoma.

Laparoscopic extraperitoneal paraaortic lymphadenectomy: a study of its applications in gynecological malignancies.

OBJECTIVES: To describe our experience of laparoscopic extraperitoneal paraaortic lymphadenectomy and to study the feasibility, safety and applications of this technique in managing cervical, ovarian and endometrial carcinomas. METHODS: Our study included 32 women with cervical, ovarian or endometrial cancers undergoing laparoscopic extraperitoneal paraaortic lymphadenectomy between December 1997 and May 2002. The operating time, nodal yield, hospital stay and complications were recorded prospectively. The impact on the overall management was assessed by comparing the preoperative therapeutic plan with that following surgicopathological staging. RESULTS: The median nodal yield was 12 nodes, median-operating time was 80 min and the median hospital stay was 2 days. The median follow-up was 15.25 months. Lymphadenectomy was successful in all but one woman who had a peritoneal tear causing CO(2) gas leakage. Complications included one case each of pulmonary embolism, umbilical hernia, lymphocoele, pelvic collection and left-thigh cellulitis. In all women, the need for adjuvant chemotherapy or extended field radiotherapy (EFRT) was based on nodal histology. The primary plan of management was changed in 22.6% women. In the endometrial and cervical cancer group, 8.3% women deferred and 20.8% additionally received EFRT. All women with ovarian cancer (stage I) were completely staged and avoided chemotherapy. CONCLUSIONS: Laparoscopic extraperitoneal paraaortic lymphadenectomy is feasible with minimal complications, acceptable nodal yield and short hospital stay. It accurately identifies those cervical and endometrial cancers requiring extended field irradiation as part of their adjuvant therapy. It can be effectively applied in staging early ovarian cancers to determine the need for adjuvant chemotherapy.

Role of MR imaging in the selection of patients with early cervical carcinoma for fertility-preserving surgery: initial experience.

PURPOSE: To assess whether magnetic resonance (MR) imaging can be used for reliable prediction of proximal extension of cervical carcinoma into the myometrium. MATERIALS AND METHODS: Thirty patients with early cervical carcinoma underwent MR imaging with use of a 1.5-T magnet prior to surgery. The MR images were analyzed by two radiologists, unaware of the histopathologic findings, for the relationship of the tumor to the internal os and extension of the tumor into the myometrium. Findings at MR imaging were compared with those at histopathologic examination. RESULTS: At MR imaging, 24 patients were considered not to have tumor extension proximal to the internal os and into the myometrium. All tumors were confirmed histopathologically. In six patients thought to have myometrial tumor invasion at MR imaging, five tumors were confirmed histopathologically; in one, tumor extended up to the internal os but did not involve the myometrium. CONCLUSION: This is a small study, but MR imaging appears accurate in the prediction of myometrial tumor involvement and in showing the relationship of cervical carcinoma to the internal os and, hence, the patient's suitability for trachelectomy.

Ultrasound assessment of ovarian cancer risk in postmenopausal women with CA125 elevation.

We have previously shown that, in asymptomatic post-menopausal women, serum CA125 elevation is associated with a 36-fold increase in risk of ovarian cancer. This study was undertaken to assess the value of pelvic ultrasound for further stratification of ovarian cancer risk. Of 22,000 post-menopausal women, aged > or = 45 participating in an Ovarian Cancer Screening Trial, 741 with a CA125 > or = 30 U ml(-1) underwent pelvic ultrasonography. Twenty index cancers (primary invasive epithelial carcinomas of the ovary and fallopian tube) were diagnosed amongst these 741 women during a median follow-up of 6.8 years. Ultrasound results separated the women with CA125 elevation into two groups. Those with normal ovarian morphology had a cumulative risk (CR) of index cancer of 0.15% (95% confidence interval (CI) 0.02-1.12) which is similar to that of the entire population of 22,000 women (0.22%, 95% CI 0.18-0.30). In contrast, women with abnormal ovarian morphology had a CR of 24% (15-37) and a significantly increased relative risk (RR) of 327 (156-683). Ultrasound can effectively separate post-menopausal women with raised CA125 levels into those with normal scan findings who are not at increased risk of index cancer and those with abnormal findings who are at substantially increased risk of index cancer.

Serum CA125 elevation and risk of clinical detection of cancer in asymptomatic postmenopausal women.

BACKGROUND: This study was undertaken to assess the correlation between CA125 elevation, a past history of cancer, and future risk of a diagnosis of cancer among asymptomatic postmenopausal women. METHODS: The subjects consisted of a study group of 771 women with elevated CA125 (> or =30 U/mL) and a control group of 771 women with CA125 <30 U/mL. They were selected from a prospective ovarian carcinoma screening trial of 22,000 postmenopausal women followed for a mean of 2269 days. RESULTS: Subjects in the study group were more likely to have a past history of cancer than subjects in the control group (odds ratio [OR] 2.31, 95% confidence interval [CI] 1.49-3.58). Much of the difference in cancer risk prior to CA125 testing was attributable to a past history of breast carcinoma (OR 2.53, 95% CI 1.45-4.42), but CA125 elevation did not predict recurrence of breast carcinoma. Subjects in the study group were also more likely to develop cancer in the future (OR 2.53, 95% CI 1.61-3.97). This difference was due to an increased risk of gynecologic cancer (OR 30.09, 95% CI 4.09-221.59). CA125 elevation was not associated with an increase in the future risk of developing breast carcinoma (OR 1.19, 95% CI 0.53-2.66) or nongynecologic cancer (OR 1.43, 95% CI 0.86-2.36). CONCLUSIONS: Elevated CA125 in asymptomatic postmenopausal women is not a predictor of nongynecologic cancer or recurrence of cancer, and further investigation should be limited to the detection of gynecologic cancers.

Increased mortality in postmenopausal women with serum CA125 elevation.

OBJECTIVES: Serum CA125 is used in monitoring treatment and detecting recurrence in ovarian cancer (OC). We have also shown that CA125 can be used with ultrasound for the early detection of OC. However, physiological, benign, and malignant conditions are also associated with CA125 elevation. The aim of the study was to determine the prognostic implications of CA125 elevation in asymptomatic postmenopausal women. METHODS: The study involved 771 volunteers in an OC screening trial of 22,000 women who had elevated serum CA125 levels (>/=30 U/ml). The control group consisted of an equal number of volunteers with normal levels. Survival was analyzed from the first point of CA125 elevation. Univariate analyses utilized the log-rank chi2 test. A logistic model was constructed for the multivariate analyses. RESULTS: The mean duration of follow-up was 1614 days (SD 897 days). Eighty-four women died (elevated CA125 group-62, control group-22). Univariate analyses showed that mortality in the elevated CA125 group was significantly greater (log-rank chi2 = 23.556, P < 0.0001, RR = 2.76), even when preexisting morbid conditions were excluded (log-rank chi2 = 14.644, P = 0.0001, RR = 2.4). Multivariate analysis showed that CA125 elevation, age (>60 years), and a prior history of cancer were associated with a poor prognosis. CONCLUSIONS: Serum CA125 elevation is associated with a significantly increased risk of death from all causes in the next 5 years. These findings may have implications for asymptomatic postmenopausal women with CA125 elevation.

Screening for ovarian cancer: a pilot randomised controlled trial.

BACKGROUND: The value of screening for ovarian cancer is uncertain. We did a pilot randomised trial to assess multimodal screening with sequential CA 125 antigen and ultrasonography. METHODS: Postmenopausal women aged 45 years or older were randomised to a control group (n=10,977) or screened group (n=10,958). Women randomised to screening were offered three annual screens that involved measurement of serum CA 125, pelvic ultrasonography if CA 125 was 30 U/mL or more, and referral for gynaecological opinion if ovarian volume was 8.8 mL or more on ultrasonography. All women were followed up to see whether they developed invasive epithelial cancers of the ovary or fallopian tube (index cancers). FINDINGS: Of 468 women in the screened group with a raised CA 125, 29 were referred for a gynaecological opinion; screening detected an index cancer in six and 23 had false-positive screening results. The positive predictive value was 20.7%. During 7-year follow-up, ten further women with index cancers were identified in the screened group and 20 in the control group. Median survival of women with index cancers in the screened group was 72.9 months and in the control group was 41.8 months (p=0.0112). The number of deaths from an index cancer did not differ significantly between the control and screened groups (18 of 10,977 vs nine of 10,958, relative risk 2.0 [95% CI 0.78-5.13]). INTERPRETATION: These results show that a multimodal approach to ovarian cancer screening in a randomised trial is feasible and justify a larger randomised trial to see whether screening affects mortality.

Ovarian cancer identified through screening with serum markers but not by pelvic imaging.

Woolas RP, Oram DH, Jeyarajah AR, Bast RC Jr, Jacobs IJ. Ovarian cancer identified through screening with serum markers but not by pelvic imaging. This study evaluated the possible role of 3 additional tumor markers to CA 125 among postmenopausal volunteers participating in a sequential multimodal ovarian cancer screening study. In 82 asymptomatic women the finding of a serum CA 125 level of > 30 U/ml precipitated pelvic ultrasound examination. Levels of CA15-3, CA72-4 and CA19-9 were subsequently determined in sera stored from the time of the CA 125 assay. Following ultrasound 29 women underwent surgery for benign conditions. The remaining 53 women underwent 2 years of surveillance. In 5 of these women a diagnosis of ovarian cancer was established between 6 and 10 months after their initial investigation. Elevated levels of at least one of the 3 additional tumor markers were present in the serum, prior to ultrasound abnormalities being detected, in 4 (80%) of the women who developed cancer. At least one of this 3-marker panel was elevated in 29% of the 48 women who have not developed cancer and 14% of the 29 women undergoing surgery for benign conditions. Information complementary to pelvic ultrasound examination for the preclinical detection of ovarian cancer could be obtained through multiple marker assay. Coordinated elevated serum levels of tumor markers could increase the sensitivity of this sequential screening protocol.

Long-term follow-up of gonadotrophin-releasing hormone analog treatment for recurrent endometrial cancer.

To test the antitumor effect of gonadotrophin-releasing hormone (GnRH) analogs, 32 consecutive patients with recurrent endometrial cancer that had progressed through conventional treatments were entered into an open observational trial of treatment with this class of compounds. Patients recruited had progressive, symptomatic, and measurable disease. Treatment was with monthly subcutaneous injections of GnRH analog. Measurements of gonadotrophins, sex hormones, and tumor dimensions were made together with repeat biopsy when possible to assess response to treatment. An objective response was seen in nine patients (28%, 95% CI 13-43%). Responses were seen within the first 2 months of treatment and included pelvic as well as distant sites of recurrence. Significantly greater response rates were seen in previously irradiated sites when compared with nonirradiated sites of recurrence (0.01 > P > 0.001). There was no significant difference between the response in patients with G3 lesions compared with patients with G1/G2 lesions (P > 0.5). Response did not correlate with previous progestogen exposure. No evidence of disease flare or drug toxicity was observed. GnRH analogs have a significant and durable antitumor effect in recurrent endometrial cancer which warrants further examination in comparison with progestogens.
