Performance of office hysteroscopy and endometrial biopsy for detecting endometrial disease in women at risk of human non-polyposis colon cancer: a prospective study.

The objective of this study was to report the value of diagnostic hysteroscopy and endometrial biopsy for the detection of complex atypical hyperplasia or cancer in asymptomatic human non-polyposis colon cancer (HNPCC) patients. The secondary objective was to evaluate the accuracy of hysteroscopy, using endometrial biopsy as a gold standard. Consecutive patients at risk of HNPCC evaluated between January 1, 1999, and June 30, 2006 were included if they underwent diagnostic hysteroscopy at least once. Patients with a history of hysterectomy and those unwilling to undergo diagnostic hysteroscopy were not included. Yearly follow-up evaluations included diagnostic hysteroscopy, with endometrial biopsy. Hysteroscopic and histologic findings were recorded and compared. We included 62 patients, of whom 13 had mismatch repair gene mutations and 49 met Amsterdam II criteria. Of 125 attempted hysteroscopies, 11 (8%) failed. Hysteroscopy showed normally appearing mucosa in 46 cases, nonmalignant lesions in 65 cases, and possibly malignant lesions in 3 cases with abnormal uterine bleeding. Endometrial biopsy was attempted in 116 cases and failed in 12 (10%). Three cases each of simple hyperplasia and of cancer were diagnosed. No preinvasive or invasive lesions were found in asymptomatic women. When compared to endometrial biopsy, sensitivity of hysteroscopy was 100% for the detection of hyperplasia or cancer. No cases of cancer were diagnosed in asymptomatic patients in our study. However, diagnostic hysteroscopy ensured the diagnosis of endometrial adenocarcinoma in HNPCC women with bleeding. Nevertheless, usefulness and optimal modalities of screening remain to be determined.

Peritoneal tuberculosis revealed by carcinomatosis on CT scan and uptake at FDG‐PET

Peritoneal tuberculosis is uncommon in industrialised countries. The resurgence of this insidious and non-specific form of ‘carcinomatosis’ is promoted by immune suppression (especially Human Immunodeficiency Virus), migration, and poverty. There are no pathognomonic clinical, radiologic or laboratory tests. In its peritoneal form, tuberculosis cannot be differentiated from ovarian cancer except by histopathology.

Performance of laparoscopy in identifying malignant ovarian cysts.

BackgroundPeroperative identification of malignancy is crucial to management planning for ovarian cysts. The aim of this study was to evaluate the performance of laparoscopy in identifying malignant ovarian cysts.MethodsPatients undergoing laparoscopy for ovarian cysts from 1998 to 2001 were enrolled prospectively. Physical findings, Doppler ultrasonography, and serum CA 125 served to compute two risk-of-malignancy indexes (RMI-1 and RMI-2), and laparoscopy findings served to categorize lesions as benign, possibly malignant, or malignant. Frozen sections were examined as needed. Final histology was the reference.ResultsOf 313 patients, 294 had benign cysts, six borderline lesions, and 13 malignancies. Sensitivity and specificity were respectively 84 and 93% for RMI-1, 92 and 80% for RMI-2, 100 and 99% for laparoscopy, 91 and 100% for frozen sections, and 100 and 100% for laparoscopy plus frozen sections, which had 100% negative predictive value. Six (1.8%) adverse events occurred.ConclusionsLaparoscopy reliably identifies ovarian cancer and borderline disease. Morbidity is low compared to oncologic surgery.

Value of three-dimensional contrast-enhanced power Doppler ultrasound for characterizing adnexal masses

Aims:  The aim of this study was to assess the diagnostic performance of 3‐D contrast‐enhanced power Doppler ultrasonography (3‐D CEPDUS) for differentiating benign and malignant adnexal masses.

Sono-Guided Endometrial Biopsy: Comparison with Hysteroscopy Biopsy

Objective: To assess the feasibility, tolerance and diagnostic accuracy of endometrial biopsy (EB) during sonohysterography (SH) compared to EB after hysteroscopy (HSC) in endometrial disorders. Methods: 105 consecutive patients with irregular uterine bleeding were included prospectively in the calendar year 2001. SH and flexible HSC were performed in an office setting, subsequently and in a random order, by two different practitioners blind to the former experiment. SH-EB was performed using a 3.1-mm ultrasound-guided Bernard catheter in the uterine cavity still partly distended and with a gentle 20-ml syringe vacuum aspiration. The biopsy was directed on focal lesions or else randomly when no targets had previously been found. A Cornier Pipelle® was used to perform EB after HSC. We investigated all patients by biopsy, independent of the endometrial thickness. HSC-EB was the gold standard. Results: For both methods, cervical catheterism was impossible in 20 patients, 75 of them successfully underwent both exams. Duration and tolerance were similar. SH was effective in the distinction between normal and pathologic cavities, as well as in the diagnosis of polyps. Endometrium appeared significantly thinner with HSC (1.8 mm) when compared to SH (2.9 mm, p < 0.05). Histological endometrial assessment failed in 30 cases of SH-EB and in 22 cases in HSC-EB (NS). There was a poor correlation of the histological results of both techniques. Hyperplasia has never been diagnosed by SH-EB, whereas 3 EB issued from HSC-EB brought up this diagnosis. Conclusion: SH-EB with our technique did not improve the diagnostic potential of SH and severe diagnosis was missed. Histological assessment should fail less when we exclude endometrial atrophy. The diameter of the catheter and the aspiration technique must be revised and the learning curve must be considered. Our technique cannot replace EB by HSC.
