BACKGROUND: Cervical carcinoma occurs frequently in young women who would like to preserve their childbearing potential. For those with early stage invasive lesions, the authors designed and performed radical trachelectomy, a surgical procedure that preserves the functions of the uterus. METHODS: Radical trachelectomy combines laparoscopic (for pelvic lymphadenectomy) and transvaginal approaches. Between April 1987 and December 1996, 56 patients were scheduled for this procedure, and 47 underwent it. The charts of these patients were retrospectively reviewed for medical and obstetric history, characteristics and complications of surgical procedures, pathologic findings, postoperative obstetric results, and cancer recurrences. RESULTS: The mean durations of the laparoscopic and vaginal steps of the procedure were 62 and 67 minutes, respectively. One intraoperative complication (cystotomy) and seven postoperative complications (drainage of pelvic collection) were observed. The pathologic tumor classification was International Union Against Cancer (UICC) pT1a1 (International Federation of Gynecology and Obstetrics [FIGO] Stage pIA1) in 5 cases, UICC pT1a2 (FIGO Stage pIA2) in 13 cases, UICC pT1b (FIGO Stage pIB) in 25 cases, UICC pT2a (FIGO Stage pIA2) in 1 case, and UICC pT2b (FIGO pIIB) in 3 cases. The mean follow-up was 52 months. Two recurrences (4%) were observed (one lateropelvic and one distant), and one patient died of disease progression. Despite a 25% rate of late miscarriages, 13 normal children were born after radical trachelectomy. CONCLUSIONS: In young patients affected by early invasive cervical carcinoma, radical trachelectomy does not appear to increase the rate of recurrence. It carries a relative risk of infertility and late miscarriage but makes it possible for some patients to become pregnant and give birth to normal newborns. Thus, it seems reasonable to offer this procedure in selected cases, provided that each patient is fully informed and the surgeon properly trained.
More than 50% of spontaneous abortions (SAs) have abnormal chromosomes; the most common abnormalities are trisomy, sex chromosome monosomy, and polyploidy. Conventional cytogenetic analysis of SAs depends on tissue culturing and is associated with a significant tissue culture failure rate and contamination by maternally derived cells. Comparative genomic hybridization (CGH), in combination with flow cytometry (FCM), can detect numerical and unbalanced structural chromosomal abnormalities associated with SAs while avoiding the technical problems associated with tissue culture. Routine cytogenetic and CGH analysis was performed independently on tissue from 301 SAs. Samples shown to be chromosomally balanced by CGH were analyzed by FCM to determine ploidy. Of 253 samples successfully analyzed by both approaches, there was an absolute correlation of results in 235 (92.8%). Of the 18 cases with discrepancies between cytogenetic and CGH/FCM results, an explanation could be found in 17. Twelve samples produced a 46,XX karyotype by cytogenetics, whereas CGH/FCM demonstrated aneuploidy/polyploidy or a male genome, indicating maternal contamination of the tissue cultures. In two cases, where tetraploidy was demonstrated by cytogenetics and diploidy by FCM, tissue culture artifact is implied. In three cases, CGH demonstrated an aneuploidy, and cytogenetics demonstrated hypertriploidy. In one unexplainable case, aneuploidy demonstrated by CGH could not be detected by repeat CGH analysis, conventional cytogenetic, or FISH analysis. These results demonstrate that CGH supplemented with FCM can readily identify chromosomal abnormalities associated with SAs and, by avoiding maternal contamination and tissue culture artifacts, can do so with a lower failure rate and more accuracy than conventional cytogenetic analysis.
We tested whether familial aggregation of Down syndrome and Alzheimer's disease (AD) is present for trisomies of other autosomes. We compared rates of Alzheimer-like dementia in the parents of women with trisomic pregnancy losses (n = 109) with those in parents of women with chromosomally normal losses (n = 151) and births (n = 216). Relative risks of Alzheimer-like dementia in parents of women with trisomic losses were 1.2 (95% CI 0.6, 2.2) and 0.9 (95% CI 0.5, 1.5) in comparison to parents of women with chromosomally normal losses and births, respectively. Associations were similar among women whose index pregnancy occurred before age 35 or later. Our data do not support an association between the occurrence of AD and trisomy of all autosomal chromosomes. They raise the possibility that familial aggregation with AD is specific to trisomy 21.
