Trocar-site metastasis is not always due to laparoscopy.

The use of laparoscopic surgical techniques for the management of gynecologic malignancies has increased over the last years. Metastasis developing at the trocar insertion site is an emerging problem. We present the case of a 66-year-old woman with endometrial cancer who was diagnosed with an umbilical tumor after laparoscopically assisted vaginal hysterectomy (LAVH) and bilateral salpingoophorectomy. The interval between LAVH and diagnosis of the umbilical tumor was 13 months. The tumor was excised, and metastasis of endometrial cancer was histologically confirmed. Review of computer tomograms taken before LAVH showed a tumor in the umbilical area that had not been recognized before therapy. Therefore, tumor manifestation at the abdominal wall after laparoscopic surgery should not automatically be considered the result of iatrogenic spreading.

Laparoscopic lymph node staging of cervical cancer in the 19th week of pregnancy. A case report.

We present the case of a 39-year-old gravida I para 0 woman who underwent laparoscopic staging of lymph node involvement in cervical cancer in the 19th week of pregnancy. She had been diagnosed with adenosquamous carcinoma of the cervix, stage 1B1, grade 2, with tumor involvement of the lymphovascular space and tumor involved resection margins via a cone biopsy in the 16th week of pregnancy. In order to decide whether it would be safe to proceed with the pregnancy, she was submitted to the laparoscopic exposure and removal of 18 parametric and pelvic lymph nodes. One positive lymph node was detected at the right internal iliac artery; therefore, an open radical hysterectomy with paraaortic lymphadenectomy was performed. This case shows that lymph node staging for cervical cancer can be done laparoscopically in the 2nd trimester. Information yielded during the course of this procedure can be crucial in deciding whether it is possible to preserve the pregnancy.

Is the decision for colorectal resection justified by histopathologic findings: a prospective study of 100 patients with advanced ovarian cancer.

OBJECTIVE: We compare the indication for colorectal resection in patients with advanced ovarian cancer with histopathologic findings. We describe the effect on pelvic control and morbidity associated with surgery. METHODS: Between February 1995 and March 2001, 100 patients with FIGO stage IIIc ovarian cancer underwent pelvic en bloc resection with excision of the rectosigmoid colon as part of primary or secondary cytoreductive surgery. Decision for resection was made by the surgeon when tumor involvement of the cul-de-sac was suspected. Rectosigmoid infiltration was histopathologically defined as infiltration of the serosa or deeper. RESULTS: In 73 of 100 patients (73%) tumor involvement of the rectum was confirmed histopathologically: infiltration of the serosa in 28 (28%) patients, infiltration of the muscularis in 31 (31%) patients, and infiltration of the mucosa in 14 (14%) patients; in 27 (27%) patients no infiltration was found. Histopathologically confirmed pelvic R0 resection was achieved in 85 (85%) patients. In 11 (11%) patients the pelvic resection margins were tumor-involved and in four (4%) patients visible parametric tumor remained in situ. Pelvic recurrence occurred in 4 (4.7%) of 85 optimally debulked patients compared with 9 (60%) of 15 patients with suboptimal pelvic resection status (P < 0.05). End colostomy could be prevented in 94 (94%) of 100 patients. CONCLUSION: Pelvic en bloc surgery with rectosigmoid resection was justified by histopathologic outcome since deperitonealization with preservation of the rectosigmoid would have left tumor in situ in 73% of patients with suspected cul-de-sac involvement.

Screening for high-grade cervical intra-epithelial neoplasia and cancer by testing for high-risk HPV, routine cytology or colposcopy.

The validity of testing for high-risk types of human papillomavirus (HPV) in cervical cancer prevention programs is undetermined. We compared the performance on primary screening of HPV DNA testing, cytology and colposcopy in detecting cervical intra-epithelial neoplasia (CIN) grade 2 or 3 or cancer. A cohort of 4,761 women, median age 35 years, was screened by routine cytology, routine colposcopy and testing for high-risk HPV by a PCR-based method. Within an 8-month period, women with abnormal findings on cytology or screening colposcopy or in whom high-risk HPV types were detected were referred for colposcopy and biopsy. Women negative on all initial screening tests were followed by a second screening examination. To correct for work-up bias, the true prevalence of CIN 2 or 3 or cancer was estimated by projection from histologically verified subgroups. Cervical biopsies were taken in 364 women (7.6%), of whom 114 (2.4%) showed CIN 2 (n = 34) or CIN 3 (n = 71) or cancer (n = 9). High-risk HPV testing achieved bias-corrected performance measures of 89.4% sensitivity, 93.9% specificity, 35.8% positive predictive value and 99.6% negative predictive value. Bias-corrected rates of true- and false-positives by high-risk HPV testing compared to cytology (colposcopy) were about 4.5 (6.7) and 19.1 (7.4) times higher, respectively. The quality of routine cytology was controlled by computer-assisted review, and the observed number of true-positives more than doubled after adding automated review results. In middle-aged women, testing for high-risk HPV types, particularly when negative, may be used to increase the screening interval in programs for secondary prevention of cervical cancer.

Monocyte-chemo-attractant-protein-1 (MCP-1)-gene expression in cervical intra-epithelial neoplasias and cervical carcinomas.

Chemokines play a central role in the chemotactic activation of immunological effector cells. One of the currently best characterized chemokines is the monocyte-chemo-attractant protein-1 (MCP-1), which is involved in the cross-talk with cells of the monocyte-macrophage lineage. Since macrophages and macrophage-derived cytokines appear to be important in the transcriptional regulation of "high-risk" types of human papillomaviruses (HPV), we monitored MCP-1 expression by in situ hybridization (ISH) in histologically distinct stages of cervical intra-epithelial neoplasms (CIN), cervical cancer and non-HPV-associated cases of erosive endocervicitis. Here, we demonstrate that high-grade dysplasia (CIN III, n = 9) completely lacks both MCP-1 expression and CD68+-macrophage infiltration, while MCP-1-specific signals were occasionally detectable in one out of 5 CIN-II and in one out of 3 CIN-I lesions. Inspection of hyperplastic squamous epithelium adjacent to cervical carcinomas reveals high MCP-1 expression and accumulation of infiltrating macrophages. In contrast, no macrophages could be detected in corresponding hyperplastic tissue areas surrounding CIN-II and CIN-III lesions, although MCP-1 was found to be highly expressed. Finally, in agreement with our earlier in vitro data, invasive carcinomas of the cervix uteri showed MCP-1-specific hybridization signals and macrophage infiltration only in the stroma surrounding the carcinoma cells and in endothelial cells of capillaries, especially at the invasion front of the tumor, while the inner mass of the carcinomas was completely negative. On the other hand, ISH and histochemical evaluation of inflammatory, non-HPV-associated cases of erosive endocervicitis indicate strong MCP-1 expression, which is regularly accompanied by chemotactic appearance of macrophages. These observations indicate that dysregulation of MCP-1-gene expression may represent an important step during HPV-linked carcinogenesis, allowing the escape of virus-positive cells from local immune response.

Endoscopic axillary lymphadenectomy without prior liposuction. Development of a technique and initial experience.

BACKGROUND: A new technique of endoscopic axillary lymphadenectomy without prior liposuction was developed by our group. METHOD: A total of 33 patients with early stage breast cancer were treated by breast-conserving therapy and endoscopic axillary lymphadenectomy. RESULTS: The median duration of the operation was 74.9 min (range, 30-130). Operation time was significantly shorter for the last 17 patients (p < 0.05) than for the first 16 patients. There were no intraoperative complications. The median number of removed lymph nodes was 14.5 (range, 2-28). Postoperatively three patients developed a seroma, one of which required evacuation. At postoperative day 5, arm mobility was unrestricted in 26 patients (78.7%); nine patients (27.2%) reported a loss of sensation in the outer side of the upper arm related to dermatome C5. One patient developed a temporary alar scapula, and one patient developed an axillary abscess 9 weeks after axillary lymphadenectomy during radiation therapy. After a median follow-up of 4.6 months seven patients reported persistent impairment of sensation, but all patients had regained full shoulder mobility. CONCLUSION: Endoscopic axillary lymphadenectomy can be done safely without prior liposuction.

Distribution of 14 high risk HPV types in cervical intraepithelial neoplasia detected by a non-radioactive general primer PCR mediated enzyme immunoassay.

AIM: To evaluate the presence of high risk human papillomaviruses (HPV) in cervical smears showing intraepithelial neoplasia (CIN). METHODS: The presence of 14 high risk HPV was evaluated in 114 cervical smears with CIN of different degrees, by comparing a non-radioactive polymerase chain reaction (PCR) enzyme immunoassay (EIA) with conventional PCR followed by radioactive Southern blot hybridisation. General primer PCR amplicons detecting low risk and high risk HPV were typed for 14 different high risk HPV types (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) by a non-radioactive PCR-EIA. Virus load of HPV 16 positive CIN was assessed using the semiquantitative PCR-EIA. RESULTS: Histological evaluation confirmed CIN I in 49 cases (mean age 29.0 years, range 17 to 52), CIN II in 31 cases (mean age 30.8 years, 18 to 54), and CIN III in 34 cases (mean age 31.1 years, 16 to 57). The non-radioactive PCR-EIA showed an overall agreement rate of 90% (kappa value 0.75) when compared with conventional general primer PCR followed by radioactive Southern blot hybridisation. High risk HPVs were detected in 47% of CIN I, 77% of CIN II, and 97% of CIN III (p < or = 0.02). HPV types 39, 51, 56, and 58 were found in CIN I exclusively (between 2% and 8%). HPV 16 and HPV 31 were detected in 12% and 2% of CIN I, 35% and 21% of CIN II, and 74% and 13% of CIN III, respectively (p < or = 0.03 and p < or = 0.04). The virus load estimated by the semiquantitative PCR-EIA of HPV 16 was similar in CIN I, CIN II, and CIN III. CONCLUSIONS: The PCR-EIA has high clinical sensitivity for detecting CIN II/III (90%). There was a significantly higher prevalence rate of HPV 16 and 31 in CIN III than in CIN I and II.

Laparoscopic assistance for extended radicality of radical vaginal hysterectomy: description of a technique.

OBJECTIVE: We developed and standardized a surgical technique, which allows radical hysterectomy by a combined laparoscopic and vaginal approach with radicalness equivalent to a type III procedure according to Rutledge. METHOD: Thirty-six consecutive patients with cervical cancer stage IB1-IIIA with high risk for parametrial involvement were treated between May 1996 and March 1998. RESULTS: Bilateral para-aortic and pelvic lymphadenectomy and resection of the cardinal ligaments was performed laparoscopically using bipolar coagulation. Dissection of the ureters and resection of bladder pillars and uterosacral ligaments was performed transvaginally. On average 6.5 cm of cardinal ligament could be removed per side. CONCLUSIONS: With the laparoscopic-vaginal technique described a radical hysterectomy type III can be performed.

Laparoscopic para-aortic and pelvic lymphadenectomy: experience with 150 patients and review of the literature.

OBJECTIVE: The clinical usefulness of laparoscopic pelvic and para-aortic lymphadenectomy for staging and therapy of gynecological cancer was analyzed prospectively. METHOD: Laparoscopic para-aortic and pelvic lymphadenectomy was performed in 150 patients with cervical (n = 96), endometrial (n = 41), or ovarian cancer (n = 13). Lymphadenectomy was combined with laparoscopically assisted vaginal radical hysterectomy in 70 patients, with laparoscopically assisted vaginal hysterectomy and/or bilateral salpingo-oophorectomy and/or appendectomy and/or omentectomy in 24 patients, with trachelectomy in 2 patients, and with laparoscopic radical hysterectomy in 2 patients; lymphadenectomy alone was performed in 52 patients. Right-sided para-aortic lymphadenectomy extended to the level of the right ovarian vein; left-sided dissection reached the level of the inferior mesenteric artery. In ovarian tumors, dissection was extended to the level of the renal vessels; in addition, the ovarian vessels were removed with the surrounding tissue. Peri- and postoperative data were collected prospectively to monitor progress of surgical performance. RESULTS: Mean operative time was 36 min (15-105 min) for right-sided para-aortic and 24 min (12-49 min) for left-sided para-aortic lymphadenectomy; bilateral pelvic lymphadenectomy took 64 min (44-110 min). On average 26.8 (10-56) pelvic lymph nodes and 7.3 (0-19) para-aortic lymph nodes were sampled. Major vessels were injured in 7 patients of which 4 patients required laparotomy. Patients undergoing lymphadenectomy alone were admitted for 3.2 days on average. CONCLUSIONS: Laparoscopic para-aortic and pelvic lymphadenectomy is effective for staging and treatment of gynecologic cancers.

Value of laparoscopic evaluation of paraaortic and pelvic lymph nodes for treatment of cervical cancer.

OBJECTIVE: Laparoscopy was used to identify and localize suspicious lymph nodes in patients with cervical cancer. STUDY DESIGN: Eighty-four patients with cervical cancer International Federation of Gynecology and Obstetrics stage IA2 to IV were staged by laparoscopic paraaortic and pelvic lymphadenectomy. The accuracy of laparoscopic assessment of lymph node status was compared with the histologic result. Positive lymph nodes were localized topographically by use of laparoscopy. RESULTS: Sensitivity and specificity of laparoscopic evaluation for identifying positive paraaortic and pelvic lymph nodes was 92.3%. Combination of laparoscopic evaluation and frozen section helped to diagnose all patients with involved lymph nodes correctly. In 13 of 84 (15.4%) patients the result of lymph node assessment by laparoscopic evaluation and frozen section changed primary therapy. In two of these patients one positive lymph node was located in the lateral part of the cardinal ligament, and the hysterectomy was extended to be a more radical procedure. CONCLUSIONS: Laparoscopic evaluation identified the lymph node status in patients with cervical cancer with high accuracy. Topographic localization showed that the lateral part of the cardinal ligament is involved early in lymph node spread.

[Abdominal actinomycosis with IUD].

We report a case of abdominal actinomycosis in a 54 year old woman using an intrauterine device for a period of 8 years. The most important finding was a tuboovarialabscess at the left pelvic side with involvement of the serosa of the jejunum, ileum, sigma, and omentum majus. Intraoperative exploration showed a solid retroperitoneal infiltration between the pelvic side wall and sigma. Another infiltration was found on the left side of the abdominal wall. The diagnosis was confirmed by histopathological examination and the patient was treated by a combination of Aminopenicillin and Metronidazol. After a period of three months we observed a complete regression of the clinical and the MRI findings.

[Value of laparoscopic pelvic lymph node excision in inguinal vulvar carcinoma metastasis].

We performed a laparoscopic pelvic lymphadenectomy in three patients with vulvar cancer FIGO stage II or III and positive inguinal lymph nodes. Computertomographical and lymphographical findings of pelvic lymph nodes did not correlate with the histological findings in two patients: Surgical staging up-graded the clinical stage in one patient. No intra- or postoperative complications were encountered. Laparoscopic pelvic lymphadenectomy in inguinal metastasizing vulvar cancer is a valuable method with low peri- and postoperative morbidity.

[Laparoscopic para-aortic and pelvic lymph node excision--initial experiences and development of a technique].

It was the aim of this study to establish and analyze the laparoscopic technique of para-aortic and pelvic lymphadenectomy. During a one year period (from August 1994 till July 1995) 42 patients underwent pelvic and para-aortic laparoscopic lymphadenectomy. In 29 cases cervical cancer, in 11 cases endometrial cancer and in 2 cases tumors of low malignant potential of the ovary were the indication for lymphadenectomy which was combined with radical vaginal hysterectomy in 19 patients or simple vaginal hysterectomy in 13 patients. During the observation period the mean operating time for para-aortic and pelvic lymphadenectomy decreased and the efficiency of the lymphadenectomy increased significantly: the mean operating time for the first 10 para-aortic lymphadenectomies was 52 minutes and for the pelvic lymphadenectomies 141 minutes, respectively. For the last 10 procedures the para-aortic part took 35 minutes and the pelvic part 110 minutes. Whereas at the beginning of the study a mean of 25 lymph nodes were removed, a mean of 36 lymph nodes were sampled during the last 10 procedures. In 3 patients operative injuries to major vessels were encountered of which two were followed by laparotomy. In 3 other patients laparotomy due to postoperative hemorrhage was necessary. These 6 complications occurred during the first half of the study and were not encountered during the following operations by changing from monopolar to bipolar coagulation and by modifying the regimen for perioperative thrombosis prophylaxis. In the first half of the study in 9 women blood transfusions were necessary and in the second half only 4 patients had to be transfused. In the first 10 patients the mean intraoperative blood loss was 1300 cc, in the last 10 patients 300 cc. After a short learning curve laparoscopic para-aortic and pelvic lymphadenectomy is a safe and effective technique for staging cervical, endometrial, and early ovarian cancers. Though this technique is no standard procedure results of this pilot study warrant prospective studies comparing this technique with conventional procedures.

[Early stomach cancer in our clinical sample].

In the period from 1971 to 1980 we studied 11 650 patients undergoing endoscopy of the stomach. We found in 427 patients a gastric cancer. In 63 patients we found an early cancer, according to 14% of all gastric cancers. The main symptoms were pain and loss of appetite. In 34% of the patients the duration of complaints was more than 1/2 year. In more than 50% the early cancer was located in the distal part of stomach. In 52% we observed the ulcerative lesion of the gastric mucosa. The histological findings were in 52% the intestinal type and in 72% the diffuse type of early gastric cancer. The precise diagnosis of an early cancer based on the histological examination of the gastric wall after gastric resection, with the exception of loopectomy and polypectomy with well-defined diagnosis of an early cancer. By the aid of preventive examination of patients with so-called precancerous condition of the gastric mucosa we see a possibility to increase the detection of early gastric cancer.

[Sarcoidosis involvement and adenocarcinoma of the stomach].

A 59-years old woman showed 5 years after the diagnosis of a sarcoidosis of stage II--III according to Wurm and Reindell an abdominal symptomatology in the sense of an ulcerous disease. Radiological, endoscopical and bioptical examinations revealed a small contraction of the antrum, an ulcus at first diagnosed as benign and an adenocarcinoma. In the resected part of the stomach were found noncaseating granulomas with Epithelioid cells and Giant cells as well as the adenocarcinoma. 1 1/2 years after partial resection of the stomach (B II) a recurrence of the carcinoma near the anastomosis and metastases in the lymphonoduli of the abdomen were found by autopsy. Thoracic of abdominal manifestations of the sarcoidosis could no longer be demonstrated.

[Results of coloscopic polypectomy in respect of the dignity (author's transl)].

The commonest type of polyps in the large intestine in our series of 506 polypectomies in 262 patients were adenomas (64%) especially tubular adenomas. Severe epithelial atypia being present in 11% of all adenomas and it was three times more discovered in villous adenomas than in tubular forms and with increasing adenomas size. Because severe epithelial atypia could be observed in polyps with diameters less than 5 mm it should be demanded to remove each polyp for an exact histological examination independent of his size. Single forceps biopsies of polyps do not allow the estimation of their further development in view of malignancy.
