[Identification and management of HNPCC syndrome (hereditary non polyposis colon cancer), hereditary predisposition to colorectal and endometrial adenocarcinomas].

BACKGROUND: The HNPCC syndrome (hereditary nonpolyposis colon cancer) is an inherited condition defined by clinical and genealogical information, known as Amsterdam criteria. In about 70% of cases, HNPCC syndrome is caused by germline mutations in MMR genes, leading to microsatellite instability of tumor DNA (MSI phenotype). Patients affected by the disease are at high risk for colorectal and endometrial carcinomas, but also for small intestine, urothelial, ovary, stomach and biliary tract carcinomas. HNPCC syndrome is responsible for 5% of colorectal cancers. Identification and management of this disease are part of a multidisciplinary procedure. METHODS: Twelve experts have been mandated by the French Health Ministry to analyze and synthesize their consensus position, and the resulting document has been reviewed by an additional group of 4 independent experts. MAIN RECOMMENDATIONS: The lack of sensitivity of Amsterdam criteria in recognizing patients carrying a MMR germline mutation led to an enlargement of these criteria for the recruitment of possible HNPCC patients, and to a 2-steps strategy, asking first for a tumor characterization according to MSI phenotype, especially in case of early-onset sporadic cases. The identification of germline MMR mutations has no major consequence on the cancer treatments, but influences markedly the long-term follow-up and the management of at-risk relatives. Gene carriers will enter a follow-up program regarding their colorectal and endometrial cancer risks, but other organs being at low lifetime risk, no specific surveillance will be proposed.

[HNPCC syndrome (hereditary non polyposis colon cancer): identification and management].

BACKGROUND: The hereditary non-polyposis colon cancer (HNPCC) syndrome is an inherited condition defined by clinical and genealogical information, known as Amsterdam criteria.

Identification and characterisation of a group of cervical carcinoma patients with profound downregulation of intratumoral Type 1 (IFNgamma) and Type 2 (IL-4) cytokine mRNA expression.

Type 1 cytokines, such as interferon gamma (IFNgamma) and interleukin-2 (IL-2), increase T cell-mediated immune responses and are considered to be beneficial for antitumour immunity. Type 2 cytokines, such as IL-4, IL-5, and IL-10, inhibit Type 1 responses and promote humoral responses. We have previously reported an association between low intratumoral IFNgamma mRNA levels and poor clinical outcome in patients with invasive cervical carcinoma. In this study, by using quantitative polymerase chain reaction (PCR), we identified a group of cervical carcinoma patients with undetectable intratumoral T cell-derived cytokine mRNAs, as IFNgamma, IL-4 and IL-17 expression could not be detected in 5, 25 and 8 of the 52 biopsies analysed, respectively. Global downregulation of Type 1 and Type 2 cytokines was observed in a subgroup of patients who more frequently presented advanced stage tumours. Biopsies of patients with no IFNgamma gene expression did not appear to be less infiltrated by T cells than control biopsies with measurable IFNgamma gene expression. These results clearly demonstrate that, in some clinical situations, the decrease in intratumoral Type 1 cytokines is not associated with a Type 2 polarisation, but rather reflects global deactivation of T cells at the tumour site. These data provide support for immunotherapy protocols designed to reverse the anergic state of T cells in cancer.

Description of two new human ovarian carcinoma models in nude rats suitable for laparoscopic experimentation.

BACKGROUND: Experimental laparoscopic trials require relevant models of ovarian carcinomatosis. METHODS: Female nude rats were inoculated intraperitoneally either with the IGR-OV1 or the NIH:OVCAR-3 human adenocarcinoma cell lines. Serial clinical checks and sacrifices were used to evaluate the rates of tumor take, survival, and patterns of tumor spread. Finally, laparoscopies with various pneumoperitoneum pressures were performed to verify the "surgical" relevancy of out models. The learning curve was measured. RESULTS: The best results were obtained when twenty-seven 106 IGR-OV1 cells and thirty-six 106 NIH:OVCAR-3 cells were injected in 28-day-old rats. The IGR-OV1 model provided a mean survival of 17.8 days (range, 13-22 days), with a high take rate (94%). The NIH:OVCAR-3 model resulted in a longer mean survival (59 days; range, 49-77) and also a high take rate (83%). The two models differed in their patterns of tumor spread: solid bulky omental metastasis having a diffuse microscopic peritoneal carcinomatosis with the IGR-OV1 line (the weight of the omental cake correlated significantly with the stage of development) and diffuse macroscopic peritoneal carcinomatosis having no large solid tumor, but visceral and paraaortic metastases, with the NIH:OVCAR-3 line. In both models, CA125 was high. Anesthesia could be performed and repeated in healthy and tumor-bearing rats. Laparoscopy was feasible, with pneumoperitoneum pressures as high as 8 mmHg lasting 1 h. Laparoscopy provided a reliable evaluation of the tumor spread into the peritoneal cavity. The plateau of the learning curve was soon obtained for take rate and survival after laparoscopy. CONCLUSION: We report two new human ovarian carcinoma xenografts in nude rats suitable for laparoscopy. The IGR-OV1 model mimics an advanced stage of the disease, and the NIH:OVCAR-3 model presents an earlier stage. These two models appear useful for experiments involving laparoscopy.

Saline contrast sonohysterography in the preoperative assessment of benign intrauterine disorders.

OBJECTIVES: To assess the value of saline contrast sonohysterography (SCSH) in the preoperative evaluation of benign intrauterine lesions. DESIGN: Patients presenting with abnormal bleeding related to benign uterine pathologies and scheduled for surgical treatment were prospectively enrolled in a study conducted between 1 January 1996 and 31 December 1997. SCSH was first carried out with the intention of establishing further surgical management (hysterectomy or hysteroscopy). The end point of the study was to compare the surgical option ultimately carried out with the one decided after SCSH. In addition, size and location of intrauterine lesions determined by SCSH were compared with those issued from surgical records. Similarly, pathologic results were juxtaposed to SCSH diagnosis. Statistical analysis used non-parametric and correlation tests. RESULTS: Two hundred and thirty-three patients were included in the study, 39.5% of whom were postmenopausal. SCSH was consistently effective in the choice of the best surgical method, because no hysterectomy was required when an operative hysteroscopy was indicated on SCSH data. Similarly, only one patient treated by hysterectomy (5.8%) could have undergone a more conservative approach. But this patient had a genital prolapse, and thus hysterectomy was a part of the treatment. SCSH correlated well with surgery for the location and size of intrauterine lesions (P < 0.001). SCSH was accurate in the diagnosis of polyps and submucous myomas (sensitivity 85.7%, specificity 95.4%). CONCLUSIONS: SCSH appears an important tool for preoperative assessment of benign intrauterine pathologies. It should be used in the selection of patients that should be scheduled for an operative hysteroscopy.

Recovery from vaginal hysterectomy compared with laparoscopy-assisted vaginal hysterectomy: a prospective, randomized, multicenter study.

OBJECTIVE: To evaluate short-term recovery of vaginal hysterectomy with those of laparoscopic assisted vaginal hysterectomy performed in a prospective, randomized multicentric study. STUDY DESIGN: Eighty patients referred for hysterectomy for benign pathology were randomized to either vaginal hysterectomy (40 patients) or laparoscopic assisted vaginal hysterectomy (40 patients). Inclusion criteria were uterine size larger than 280 g and one or more of the following: previous pelvic surgery, history of pelvic inflammatory disease, moderate or severe endometriosis, concomitant adnexal masses, and indication for adnexectomy. No upper limit of uterine size was set. All the laparoscopic and the vaginal hysterectomies were done under endotracheal general anesthesia. RESULTS: There was no statistically significant difference in terms of patient's age, parity, postmenopausal state, indication for surgery and mean uterine weight between the 2 groups. Laparoconversion was performed in three women in the laparoscopic group. Operative time was significantly shorter in the vaginal versus the laparoscopic groups 108+/-35 and 160+/-50 respectively (p<0.001). The use of paracetamol, non steroidal anti-inflammatory drugs, and opioid during hospitalization were similar in the 2 groups. There was no difference in the 1st day hemoglobin level drop, time of passing gas and stool, or hospital stay between the 2 groups. CONCLUSION: In contrast with earlier reports, there was no difference in short-term recovery between patients undergoing vaginal or laparoscopic hysterectomy. No advantage was found performing laparoscopic assisted vaginal hysterectomy in comparison with the standard vaginal hysterectomy.

Vaginal hysterectomy for enlarged uteri, with or without laparoscopic assistance: randomized study.

OBJECTIVE: To compare short-term results of vaginal hysterectomy (VH) with those of laparoscopically assisted vaginal hysterectomy (LAVH) in women with enlarged uteri. METHODS: Eighty women referred for abdominal hysterectomies for benign disease were assigned randomly to vaginal hysterectomy or LAVH. Inclusion criteria were uterine size larger than 280 g and one or more of the following traditional contraindications of vaginal hysterectomy: previous pelvic surgery, history of pelvic inflammatory disease, moderate or severe endometriosis, concomitant adnexal masses, indication for adnexectomy, and nulliparity without uterine descent. RESULTS: There were no differences in patients' mean age, parity, rate of postmenopausal state, previous pelvic surgery, preoperative hemoglobin levels, and mean uterine weight. Indications for surgery were similar between groups. No difference was found in the mean +/- standard deviation (SD) uterine weight (range) between vaginal hysterectomy and LAVH groups (424 +/- 211 g [280--930 g] and 513 +/- 360 g [290--1560 g]), respectively. Except for one bladder injury in the laparoscopic group (injury treated laparoscopically), there were no other major complications. Complication rates in vaginal and laparoscopic groups were 15% and 37.5%, respectively (P <.05). Mean operating time was shorter in the vaginal than the laparoscopic group (108 +/- 35 minutes and 156 +/- 50 minutes, respectively [P <.001]). There was no difference in first day hemoglobin level drops or hospital stays between groups. CONCLUSION: Vaginal hysterectomy can be successful even in women with enlarged uteri and other conditions considered by some to contraindicate the operation. Laparoscopically assisted vaginal hysterectomy offered no advantages over the standard vaginal hysterectomy.

Direct cost of single dose methotrexate for unruptured ectopic pregnancy. Prospective comparison with laparoscopy.

OBJECTIVES: to compare the direct cost of single dose methotrexate (MTX) and laparoscopy in the treatment of unruptured ectopic pregnancy (unruptured EP). STUDY DESIGN: A prospective nonrandomized study. Thirty-two women received intramuscular MTX (1 mg/kg) on an out-patient basis when they fulfilled the following requirements: human chorionic gonadotropin (hCG) level <5000 IU/l, hematosalpinx diameter <3 cm and peritoneal fluid <100 cc. Follow-up consisted of clinical controls and hCG assays. Twenty-seven women eligible for MTX therapy according to the above conditions underwent laparoscopic salpingectomy because some of them refused the therapy while others had contraindications to MTX. We recorded all the medical expenses related to the out-patient and in-patient management for the two treatment options. The cost was calculated according to the French General Nomenclature of Professional Acts and expressed in Euros. RESULTS: MTX resulted in a significantly lower mean direct cost in comparison with surgery (E 1145 vs. 2442, P=0.006) that was mainly due to shortened hospital stay (1.1 vs. 2.8 days, P=0.007). Conversely MTX required a significantly higher number of medical acts during the follow-up. Costs for MTX therapy were closely related to the length of hospitalization and to the duration of the follow-up. CONCLUSION: Single dose MTX provides significant cost-savings when compared to laparoscopy. Savings reach a peak for small unruptured EP because hospitalization is not required and the length of follow-up reduced.

Perioperative morbidity of gynecological laparoscopy. A prospective monocenter observational study.

BACKGROUND: To study the morbidity rate of gynecological laparoscopy and to the most influential variables. METHODS: We conducted a prospective observational study from January 1st 1992 to December 31st 1998 in a single tertiary care center. It concerned patients who underwent gynecological laparoscopic surgery performed by seniors and residents. We have prospectively recorded patients characteristics, indications for laparoscopy, leading diagnosis, main operative procedures, post-operative course, surgical and anesthetic incidents and accidents. Complications were defined as any event that would modify the usual course of laparoscopy or of the post-operative period. RESULTS: One thousand and thirty-three laparoscopies were included. 80.1% of the procedures were major or advanced laparoscopies. The overall complication rate was 3%, with a laparotomy rate of 1.2%. About half of those complications (54.8%) occurred during the installation of laparoscopy. Veress needle and first trocar insertion accounted for 23.5% of those accidents (0.3% of the procedures) and suprapubic trocar insertion for 76.5%. Hemorrhages constituted almost all of the complications occurring during the operative stage (80%). The risk increased with the level of surgery and decreased with surgeon's experience. Prior abdominal surgery had no significant effect on the overall morbidity rate. Post-operative and anesthetic complications were rare. The overall complication rate as well as the laparotomy rate were stable all along the course of the study. CONCLUSIONS: Complication rate of gynecological laparoscopy is not negligible. Efforts should be made to lower the complications induced by the installation of laparoscopy, especially for secondary trocars.

Transvaginal hydrolaparoscopy compared with laparoscopy for the evaluation of infertile women: a prospective comparative blind study.

Standard diagnostic laparoscopy is considered the gold standard to investigate tubo-peritoneal infertility. It requires general anaesthesia and full operative facilities. Due to the risk of complications, laparoscopy is frequently postponed to the final stage of infertility evaluation or even after treatment trials have failed. Transvaginal hydrolaparoscopy (THL) is based on vaginal access using a needle puncture technique and saline for distention. THL can be performed on an outpatient basis under local anaesthesia. However, little data exist concerning the accuracy of THL in comparison with laparoscopy. We conducted a prospective comparative blind trial to assess the feasibility and accuracy of THL compared with diagnostic laparoscopy in infertile women. Sixty women were assigned to undergo THL immediately prior to laparoscopy. Different operators evaluated the findings of the two procedures. In order to evaluate the accuracy of THL, findings in terms of tubal pathology, endometriosis and adhesions were analysed. The success rate of accessing the pouch of Douglas was 90.2%. Complication rate was 1.6%. THL diagnosis was correlated with that of laparoscopy in 92.3% of cases. In cases of abnormal findings by THL, there were no normal laparoscopies. Our pilot study suggests that THL is a safe and reproducible method. Retroverted uterus should be considered as a relative contraindication to THL. When a complete evaluation by THL is available, it is a highly accurate technique in comparison with the laparoscopy.

[Port-site metastases following laparoscopic surgery].

Laparoscopy for malignancy resection has been followed by description of metastatic laparoscopic port sites. Recently published clinical, experimental studies and case reports related to this problem are reviewed. Frequency of port-site metastases for gallbladder, colorectal and ovarian cancers seem to differ. Ascites and staging during laparoscopy are probably risk factors for port-site metastases. Clinical presentations of port-site metastases are exposed and experimental studies show that pneumoperitoneum, nature of gas as well as local factors were probably implicated. Hypothetical mechanisms of port-site metastases are discussed; it is likely that the aetiology are multifactorial. Preventive strategies of port-site metastases are proposed. Further research in this area is necessary to understand mechanisms of port-site metastases.

Anticoagulant therapy in pregnancy.

Anticoagulation during pregnancy should derive benefit from recent advances in anticoagulant therapy. Unfractionated heparin is at present the drug of choice for most of the indications of thromboprophylaxis as well as for acute venous thrombosis during pregnancy but it is likely that, in the near future, low molecular weight heparins will supercede this anticoagulant in many indications. One particular indication is mechanical heart valves that needs a high degree of anticoagulation. The anticoagulant of choice that carries the best efficacy-risk ratio in this situation seems to be oral anticoagulants. Pregnant women receiving anticoagulation should be considered as high-risk patients that should be managed in specialized centres. They are prone to bleeding complications that will mainly occur during delivery or in the postpartum period.

Single-dose methotrexate for unruptured ectopic pregnancy.

OBJECTIVES: To compare the effectiveness of single-dose methotrexate (MTX) and laparoscopic salpingostomy in the treatment of unruptured ectopic pregnancy (UEP). METHODS: 75 patients entered a prospective non-randomized study. Thirty-seven women were submitted to a single-dose methotrexate (Group 1) and 38 underwent laparoscopic salpingostomy (Group 2). Methotrexate (1 mg/kg) was given intramuscularly on an out-patient basis if the beta-hCG level was < 5000 IU/I and the hematosalpinx diameter was < 3 cm and the peritoneal fluid < 300 cm3 on TVS. The follow-up consisted of serial clinical examinations, beta-hCG assays, liver tests and blood cell counts. Laparoscopic salpingostomy was decided in other cases of UEP or when patients refused or could not comply with the follow-up. RESULTS: Group 1 patients (91.8%) were cured with 1-3 doses of MTX, the remainder required a laparoscopy. Seventy-three percent of them were treated on an out-patient basis. The mean time to resolution of hCG was 26.7 days. The initial beta-hCG level significantly correlated with the necessity of a surgical option and the time to resolution of beta-hCG. Whenever beta-hCG was < 3600 IU/l, all patients were cured with a single injection, without hospitalization and with a follow-up of < 27 days. Group 2 patients (81.6%) were cured with laparoscopy and 15.8% required a MTX injection for persistent EP. The mean hospital stay was significantly longer than for those that required the MTX injection (2.7 vs. 0.6; P = 0.0001), but the follow-up was shorter and required significantly less clinical examinations, sonograms and biologic tests. Finally the effectiveness of single-dose MTX and laparoscopic salpingostomy were similar (P = 0.2, 95% CI of the difference: -0.15-0.04). CONCLUSIONS: Single-dose MTX was as effective as laparoscopy in the treatment of UEP. A rigorous selection of the patients for the treatment option is mandatory to guarantee high success rates, in an out-patient basis and a short follow-up.

Nosocomial outbreak of Klebsiella pneumoniae producing SHV-5 extended-spectrum beta-lactamase, originating from a contaminated ultrasonography coupling gel.

Klebsiella pneumoniae resistant to ceftazidime was isolated from six adult women and two neonates hospitalized between July and November 1993 in the Department of Obstetrics and Gynecology of Boucicaut Hospital (Paris, France). The epidemiological investigation revealed a notably short delay (less than 48 h) between admission and contamination of the six adults and peripartum transmission to the neonates. The only environmental source of ceftazidime-resistant K. pneumoniae was the ultrasonography coupling gel used in the emergency room. Phenotypic (biotyping and antibiotyping) and genotypic (plasmid profile and pulsed-field gel electrophoresis) analysis of all the clinical isolates indicated the spread of a single strain. It produced SHV-5 and TEM-1 beta-lactamases, as demonstrated by isoelectric focusing and gene sequencing. The risk of cross-contamination in ultrasonography procedures is usually low and had not been associated so far with bacteria producing an extended-spectrum beta-lactamase (ESBL). Furthermore, this is the first time an epidemic of an SHV-5 ESBL-producing member of the family Enterobacteriaceae has been reported from a French hospital.

[Use of ultrasonography as a first-line investigation of the uterus. Results of a prospective study].

OBJECTIVE: To assess the effectiveness of hysterosonography as a first line investigation for uterine bleeding in perimenopausal women. METHODS: 185 women were enrolled in a prospective study. They underwent a hysterosonography indicated for abnormal uterine bleeding or follow-up of a treatment with tamoxifene. Patients with a normal cavity or atrophia were scheduled for a diagnostic hysteroscopy or a hormonal therapy. Patients with uterine cavity abnormalities were scheduled for surgery (operative hysteroscopy or hysterectomy). All the patients were clinically followed after the hysterosonography or the surgery. Results of hysterosonography were compared to data issued from the clinical follow-up or to pathological results when available. RESULTS: Hysterosonography was achieved in 179 patients. In all but 1 case, hysterosonography was well tolerated by the patients. We had no complication during or after the examination. Hysterosonography had a high sensitivity and specificity in the discrimination of women with normal cavity or atrophia from the ones with intrauterine lesions (respectively 96.4% and 98.3%). Hysterosonography was also accurate in the distinction of polyps from sub-mucosal myomas (sensitivity 88.2 à 90.3%, specificity: 98.6 à 95%). The measurement and localization of the lesions were accurate in an equal manner with both procedures. Hysterosonography had similar results in women treated with tamoxifene, but the failure frequency was significantly higher (13% vs 1.8%) (p < 0.05). CONCLUSIONS: Hysterosonography appears as a reliable tool for the investigation of abnormal uterine bleeding in perimenopausal women. It can distinguish women who just need a medical therapy from the ones who will require a surgical exploration. It is easy to learn, and well tolerated by the women. Hysterosonography is more sensitive and specific than transvaginal sonography in the follow-up of patients treated with Tamoxifene.

[Pseudotumor aspect of ovarian vein thrombosis].

Ovarian vein thrombosis is an unusual puerperal illness (1 in 600 deliveries) which usually recovers spontaneously or under treatment. We report a rare follow-up observation of a puerperal ovarian vein thrombophlebitis, first diagnosed by computed tomography, which evolved to a 6 x 10 cm pseudotumoral cavernoma mass after 18 months.
