Gynecologic oncology specialty.

In general, the gynaecologic oncologists should be fully equipped to manage primary treatment and most complications related to the care of patients with gynaecologic neoplasms. During the subspecialty trianing program the fellow in trianing should learn to understand and perform radical pelvic surgery, including intestinal and urology procedures, and in addition a deep knowledge of chemotherapy and radiation therapy is important for the complete treatment of gynaecologic neoplasms. The subspecialty of gynaecologic oncology has made many advances over the last few decades; there have been several changes to the management of gynaecologic cancers, which have led to improved outcome and well-being of patients.

Pelvic and aortic lymphadenectomy.

Pelvic and aortic lymphadenectomy for gynecologic malignancies has changed from a random "picking" of some pelvic and aortic lymph nodes to a well-established technique based on adequate knowledge of the patterns of spread of the primary tumor. The identification of the node groups to remove, the number of nodes to count, and the border of dissection in the different clinical situations make pelvic and aortic lymphadenectomy a reproducible surgical intervention. The large experience accumulated over the years has greatly improved the technique and perioperative and complication management. The improved knowledge of the natural history of gynecologic tumors has refined the indications for lymph node dissection. Today, pelvic and aortic lymphadenectomy is primarily a staging procedure. The therapeutic value of lymphadenectomy is recognized in the surgical treatment of cervical cancer, but it is still under evaluation in ovarian and endometrial tumors.

Early cervical carcinoma: the natural history of lymph node involvement redefined on the basis of thorough parametrectomy and giant section study.

BACKGROUND: Although parametrectomy is the most difficult step in the surgical treatment of cervical carcinoma and is the main cause of postoperative complications, little attention has been given to the patterns of parametrial spread. METHODS: Sixty-nine patients with previously untreated cervical carcinoma (Fédération Internationale de Gynécologie et d'Obstétrique [FIGO] Stage IB1, 49 patients [71%]; Stage IB2, 8 patients [12%]; and Stage IIA, 12 patients [17%]; squamous, 59 patients [86%]; and adenocarcinoma, 10 patients [14%]) underwent radical hysterectomy and pelvic +/- aortic lymphadenectomy. Hysterectomy specimens were processed with the giant section technique. To obtain a thorough three-dimensional assessment of the paracervical tissue, both the superficial and deep layers of the cervicovesical ligament (anterior parametrium) and the uterosacral ligament (posterior parametrium) were separated from the uterus and submitted for pathologic evaluation. After resection of the lateral parametrium with hemoclips, the lympho-fatty tissue remaining around the pudendal vessels was removed carefully and referred to as "the distal part of the lateral parametrium." RESULTS: When analyzing all the parametria, lymph nodes were present in 64 patients (93%). Clinically undetected parametrial involvement was found by pathologic examination in 15 Stage IB1 patients (31%), 5 Stage IB2 patients (63%), and 7 Stage IIA patients (58%). Metastases were found in the cardinal, cervicovesical, and sacrouterine ligaments and principally were comprised of lymph node and vascular space invasion. Twenty-five patients (36%) had pelvic lymph node metastases whereas concomitant parametrial involvement was observed in all patients. The overall 5-year survival was 91%, being higher for parametria and lymph node negative patients (100%) than for those with lymph node and/or parametrial metastases (78%). CONCLUSIONS: A three-dimensional pathologic assessment showed that subclinical parametrial spreading of the so-called "early" tumors (Stage IB-IIA) occurred in approximately 30-60% of these patients, and metastasis to the pelvic lymph nodes always was associated with parametrial disease. A better understanding of the patterns of parametrial diffusion will improve knowledge of the natural history of cervical carcinoma and in the future may influence the treatment of these patients. Furthermore, pathologic assessment of cervical carcinoma should be modified to evaluate correctly the parametrial status of each patient. The current routine pathologic evaluation of the parametria makes it very difficult to detect lymph node metastases and tumor emboli.

Frameshift mutations at coding mononucleotide repeat microsatellites in endometrial carcinoma with microsatellite instability.

BACKGROUND: Microsatellite instability (MI) is a frequent occurrence in endometrioid carcinoma of the endometrium (EC). Several genes known to contain mononucleotide short tracts in their coding sequences (TGF-beta RII, IGFIIR, BAX, hMSH6, and hMSH3) are likely targets for mutations in these tumors. METHODS: DNA from 24 patients with EC and MI was extracted from blood and from fresh-frozen and paraffin embedded tumor tissue. Seven of these patients were found to have metastatic spread to paraaortic lymph nodes. DNA also was studied from 10 patients with EC without MI. RESULTS: Frameshift mutations at coding mononucleotide repeats were detected by single strand conformation polymorphism analysis and DNA sequencing. Frameshift mutations were detected more frequently in BAX (11 of 24 MI positive (+) tumors; 45.8%) than in TGF-beta RII (0 of 24 tumors; 0%), IGFIIR (3 of 24 tumors; 12.5%), hMSH3 (6 of 24 tumors; 25%), or hMSH6 (0 of 24 tumors; 0%). The mutations frequently were distributed heterogeneously throughout the tumors. Overall, frameshift mutations at 1 or more of these mononucleotide repeat microsatellites were found in 17 of 24 MI+ tumors (70.8%) but in none of the 10 MI negative neoplasms. In the seven EC patients with lymph node metastases, mutations in IGFRII were found more commonly in those with metastatic (three of seven patients) rather than primary (one of seven) tumors. CONCLUSIONS: The results of the current study confirm that BAX is an important target gene in ECs with MI. The frequent detection of IGFRII frameshift mutations in lymph node metastases suggest that IGFRII may play a role in tumor progression in these patients.

Bcl-2, Bax, Bcl-x(L) and Bcl-x(S) expression in neoplastic and normal endometrium.

The two anti-apoptotic proteins Bcl-2 and Bcl-x(L), and the two pro-apoptotic proteins Bax and Bcl-x(S) were measured by Western blotting in 51 neoplastic and 8 normal endometrial samples. The corresponding mRNA levels were analyzed by semiquantitative reverse transcriptase-polymerase chain reaction in a subgroup of 19 endometrial carcinomas. Neoplastic tissues had higher amounts of Bcl-2 protein than normal tissues (p < 0.051). Bcl-x(L) followed the same trend since its levels were higher in tumor than in normal samples (p < 0.048). Interestingly, Bcl-2 and Bcl-x(L) protein content showed a trend towards an inverse correlation (r = 0.27, p < 0.052). mRNA and protein levels directly correlated only with Bcl-2 (r = 0.63, p < 0.0032). Despite the fact that the amounts of Bcl-2, Bax and Bcl-x(L) proteins in the neoplastic population were not significantly differently distributed according to the clinicopathological features of the patients, the differences observed between normal and neoplastic samples suggest that these proteins may play a role in endometrial carcinoma: long-term follow-up studies will be required to confirm this hypothesis.

Oxaliplatin or paclitaxel in patients with platinum-pretreated advanced ovarian cancer: A randomized phase II study of the European Organization for Research and Treatment of Cancer Gynecology Group.

PURPOSE: This was a multicentric, open, randomized, phase II study of single-agent paclitaxel and oxaliplatin to evaluate the efficacy of oxaliplatin in a relapsing progressive ovarian cancer patient population and to analyze the safety profile and impact of both agents on quality of life, time to progression, and survival. PATIENTS AND METHODS: Eighty-six patients with platinum-pretreated advanced ovarian cancer were randomly assigned to two arms: 41 received paclitaxel at 175 mg/m(2) over 3 hours every 3 weeks, and 45 received oxaliplatin at 130 mg/m(2) over 2 hours every 3 weeks. For inclusion, patients had to have a performance status of 0 to 2 and to have received at least one and no more than two prior cisplatin- and/or carboplatin-containing chemotherapy regimens within the last 12 months. RESULTS: Seven confirmed responses were observed in each arm, for an overall response rate in the total treated population of 17% (95% confidence interval [CI], 7% to 32%) in the paclitaxel arm and 16% (95% CI, 7% to 29%) in the oxaliplatin arm. Median time to progression was 14 weeks and 12 weeks, and overall survival was 37 weeks and 42 weeks in the paclitaxel and oxaliplatin arms, respectively. Among 63 patients with a 0- to 6-month progression-free, platinum-free interval, there were five objective responses with paclitaxel in 31 patients and two objective responses with oxaliplatin in 32 patients. Nine patients (22%) in the paclitaxel arm had grade 3 or 4 neutropenia (National Cancer Institute of Canada [NCIC] Common Toxicity Criteria). Two patients (4%) experienced grade 3 thrombocytopenia in the oxaliplatin arm. Maximum grade (grade 3) NCIC neurosensory toxicity was experienced by three patients (7%) in the paclitaxel arm and by four patients (9%) in the oxaliplatin arm. CONCLUSION: Single-agent oxaliplatin at 130 mg/m(2) every 3 weeks is active with moderate toxicity in patients with cisplatin-/carboplatin-pretreated advanced ovarian cancer.

Early feeding compared with nasogastric decompression after major oncologic gynecologic surgery: a randomized study.

OBJECTIVE: To evaluate the feasibility, safety, and tolerance of early feeding in patients undergoing surgery for gynecologic malignancies. METHODS: Patients were stratified according to operative time and type of tumor and were randomized into two arms: A) early oral feeding and B) nasogastric decompression followed by feeding at the first passage of flatus. Variables assessed included nausea, vomiting, time to first passage of flatus and stool, time elapsed before adequate tolerance of a regular diet, postoperative stay, and complications. RESULTS: Sixty-one patients were randomized into each arm. The types of tumor, the surgical procedures performed, and the operative times were similar in both groups. Early oral feeding in patients in arm A was associated with a significantly faster resolution of postoperative ileus (P < .01), with a more rapid return to a regular diet (P < .01), with an earlier first passage of stool (P < .01), and with a shorter postoperative stay (P < .05) than patients in arm B. Rates of nausea and vomiting were similar in both arms. Hindered deglutition and nasal soreness caused by the nasogastric tube were observed in 88% of patients in arm B. Insertion of a nasogastric tube was necessary in six patients in arm A (10%), and three of these had postoperative complications. Thus, early feeding was feasible in 95% of patients and did not seem to be related to preoperative chemotherapy, tumor type, or lymphadenectomy. CONCLUSION: Early feeding is feasible and well tolerated and is associated with reduced postoperative discomfort and a more rapid recovery in patients undergoing major surgery for gynecologic malignancies.

p53 overexpression is associated with cytoreduction and response to chemotherapy in ovarian cancer.

The aim of this study was to assess the association of p53 status with primary cytoreduction, response to chemotherapy and outcome in stage III-IV primary ovarian cancer patients. Immunohistochemical analysis of p53 was performed on formalin-fixed, paraffin-embedded specimens from 168 primary ovarian carcinomas by using the DO-7 monoclonal antibody. p53 nuclear positivity was found in 84 out of 162 (52%) malignant tumours. A higher percentage of p53 nuclear positivity was observed in patients with advanced stage of disease than in stage I-II (57% vs 23% respectively; P = 0.0022) and in poorly differentiated versus well/moderately differentiated tumours (59% vs 32% respectively; P = 0.0038). The multivariate analysis aimed to investigate the association of FIGO stage, grade and p53 status with primary cytoreduction in 136 stage III-IV patients showed that stage IV disease may influence the possibility to perform primary cytoreduction in ovarian cancer patients. p53-positivity also maintained a trend to be associated with poor chance of cytoreduction. In patients who underwent pathologic assessment of response, cases who did not respond to chemotherapy were much more frequently p53-positive than p53-negative (86% vs 14% respectively; P = 0.012). Moreover, patients with stage III disease and < 2-cm residual tumour were more likely to respond to treatment. In multivariate analysis, FIGO stage and p53 expression were independently correlated with pathologic response to chemotherapy. Time to progression and survival rates were shown not to be different in p53-positive versus p53-negative patients.

Epidermal growth factor receptor (EGFR) is not related to the prognosis of cervical cancer.

We analyzed the prognostic significance of epidermal growth factor receptor (EGFR) in a large prospective series of 90 cervical cancer patients observed for a long follow-up period. EGFR levels ranged from 0 to 52.1 fmol/mg protein, with a median value of 6.0 fmol/mg protein. Patients with an advanced stage of disease expressed lower EGFR levels than those with an early stage of disease (median values were 7.8 fmol/mg protein for patients with stage I-II and 4.2 fmol/mg protein for patients with stage III-IV, P = 0.013). There was no correlation between EGFR expression and other clinicopathological parameters analyzed. No significant relationship was shown between EGFR positivity and overall survival. No significant relationship between EGFR status and disease-free survival was observed. Cox univariate regression analysis using EGFR as a continuous variable showed that EGFR levels are not associated with the risk of disease recurrence after treatment or death (P-value not significant). Our data didn't seem to indicate a prognostic role of EGFR in cervical cancer.

Analysis of cyclin E and CDK2 in ovarian cancer: gene amplification and RNA overexpression.

Cyclins and their associated kinases (cdks) play a key role in controlling the cell cycle, a process whose disregulation can potentially lead to uncontrolled cell growth and hence to cancer. We have studied the role of both cyclin E and its associated kinase cdk2 in ovarian cancer. Primary, metastatic, recurrent and benign ovarian tumors were screened for cyclin E and cdk2 gene amplification. Cyclin E was shown to be amplified in 21% and cdk2 in 6.4% of the cases analyzed. Cyclin E and cdk2 RNA expression levels were determined by semi-quantitative RT-PCR analysis in a partially overlapping series of samples and compared to the expression levels of normal ovarian surface epithelial cells. Cyclin E RNA was overexpressed in 29.5% and cdk2 in 6.5% of ovarian tumors tested. We determined that in most cases gene amplification leads to higher RNA levels for cyclin E and that the overall levels of cyclin E and cdk2 RNA were correlated. We hypothesize that cyclin E and cdk2 are, in part co-regulated and that they may concur to ovarian tumor development.

Long-term survival following neoadjuvant chemotherapy and radical surgery in locally advanced cervical cancer.

The aim of this study was to analyse the long-term survival and the relationships between prognostic factors at presentation, chemoresponsiveness and disease outcome in patients with locally advanced cervical cancer treated by neoadjuvant chemotherapy and radical surgery (RS). Two consecutive studies of neoadjuvant chemotherapy containing cisplatin, bleomycin plus/minus methotrexate followed by radical hysterectomy and systematic aortic and pelvic lymphadenectomy were carried out between January 1986 and September 1990 on 130 patients with > or = 4 cm stage IB2-III cervical cancer. Survival analysis was performed using the Kaplan and Meier test and Cox's multivariate regression analysis. 128 (98%) of the patients enrolled were evaluable for clinical response and survival, 83% (106) of the patients responded to chemotherapy, with a 15% complete response rate. Logistic regression analysis demonstrated that International Federation of Gynecology and Obstetrics (FIGO) stage, cervical tumour size, parametrial involvement and histotype are highly predictive of response. Responding patients underwent laparotomy, but 8% were not amenable for radical surgery. The 10-year survival estimates were 91%, 80% and 34.5% for stage IB2-IIA bulky, IIB and III, respectively (P < 0.001). After Cox's regression analysis, the parameters significantly associated with survival were the same factors predicting response to neoadjuvant chemotherapy. No stage IB2-IIA bulky patient has so far relapsed, while 12% stage IIB and 56% stage III patients recurred. The 10-year disease-free survival estimates are 91% and 44% for stage IB2-IIB and III, respectively (P < 0.001). Metastatic nodes and persistent tumour in the parametria were the only two independent factors for disease-free survival after multiple regression analysis. After a long-term follow-up (median follow-up 98 months (20-129+)), our results give new evidence of the prognostic value of response to neoadjuvant chemotherapy and of a possible therapeutic benefit of the sequential treatment adopted which, however, must be verified in a randomised setting.

bcl-2, bax, bcl-XL, and bcl-XS expression in normal and neoplastic ovarian tissues.

The bcl-2 family of proteins includes some important regulators of apoptosis. Among these, bcl-2 and bcl-xL prevent cells from entering apoptosis, whereas bax and bcl-xS can induce cell death. Alterations in the control of this process can lead to a decrease in cell death, thus contributing to neoplastic growth. Diminished susceptibility to chemotherapy has also been attributed, in in vitro systems, to alterations in the levels of bcl-2, bax, or bcl-x. We analyzed the expression of bcl-2, bax, bcl-xL, and bcl-xS in normal and neoplastic ovarian tissues by reverse transcriptase-PCR and Western blotting. The RNA and protein levels were significantly correlated for all genes. Interestingly, the levels of these genes in normal and neoplastic tissues were significantly different: bcl-2 was higher in normal tissue (P < 0.002), whereas bax and bcl-xL were higher in carcinoma (P < 0.018 and P < 0.030, respectively). bcl-xS was present at low levels in 83% of neoplastic samples and was undetectable in normal tissue. Reverse transcriptase-PCR analysis of 74 tumors showed no major correlation with clinicopathological parameters or with response to chemotherapy. Only bax and bcl-xL were correlated with progesterone receptor levels (n = 29, r = +0.44, P < 0.0189, and r = -0.40, P < 0.035, respectively). No correlation was found with estrogen receptor levels or with p53 immunostaining. Our data indicate that the regulation of the bcl-2 family of proteins differs between normal and neoplastic ovarian tissues. Moreover, the modulation of these genes in ovarian carcinoma is different compared to other tissues; therefore, tissue specificity is very important in regulation of the bcl-2 family of proteins.

A randomized study comparing retroperitoneal drainage with no drainage after lymphadenectomy in gynecologic malignancies.

OBJECTIVE: To evaluate the clinical effectiveness of retroperitoneal drainage following lymphadenectomy in gynecologic surgery. METHODS: One hundred thirty-seven consecutive patients undergoing systematic lymphadenectomy for gynecologic malignancies were randomized to receive (Group A, 68) or not (Group B, 69) retroperitoneal drainage. The pelvic peritoneum and the paracolic gutters were not sutured after node dissection. Perioperative data and complications were recorded. RESULTS: Clinical and surgical parameters were comparable in the two groups. Postoperative hospital stay was significantly shorter in Group B (P < 0.001), whereas the complication rate was significantly higher in Group A (P = 0.01). This was mainly due to a significant increase in lymphocyst and lymphocyst-related morbidity. Sonographic monitoring for lymphocyst showed free abdominal fluid in 18% of drained and 36% of not-drained patients (P = 0.03). Symptomatic ascites developed in 2 drained (3%) and 3 not-drained (4%) patients (NS), respectively. CONCLUSIONS: Prophylactic drainage of the retroperitoneum seems to increase lymphadenectomy-related morbidity and postoperative stay. Therefore, routine drainage following lymphadenectomy seems to be no longer indicated when the retroperitoneum is left open.

Modified type IV-V radical hysterectomy with systematic pelvic and aortic lymphadenectomy in the treatment of patients with stage III cervical carcinoma. Feasibility, technique, and clinical results.

BACKGROUND: Due to the high prevalence of perioperative major morbidity and the difficulties in achieving surgical disease free margins, surgery has had no role in the treatment of patients with Stage III cervical carcinoma. METHODS: Forty-two women with International Federation of Gynecology and Obstetrics (FIGO) Stage III cervical carcinoma responding to platinum-based neoadjuvant chemotherapy underwent the maximum surgical effort, comprised of a modified type IV-V radical hysterectomy (37 patients) or anterior pelvectomy (5 patients) with systematic pelvic and aortic lymphadenectomy. Feasibility, modifications of surgical technique, and pathologic and clinical data were analyzed. RESULTS: Surgery was feasible in all 42 patients intraoperatively selected. Disease free margins were achieved in all but one patient. The median operating time was 390 minutes, and the median estimated blood loss was 800 mL. In the last series of patients, these figures declined to 320 minutes and 600 mL, respectively. Major morbidity consisted of severe intraoperative hemorrhage in two patients, pulmonary embolism in four, ureteral fistula in three, and laparocele in three. The number of lymph nodes removed ranged from 30 to 117 with a median of 56. The mean lengths of vagina and lateral parametrium resected were 55 and 48 mm, respectively. Despite perioperative chemotherapy, lymph node metastasis was present in 36% of patients, parametrial disease in 38%, and vaginal disease in 45%. After a median follow-up of 53 months, the 5-year overall and disease-free survival rates of radically operated patients were 70% and 58%, respectively. CONCLUSIONS: Thanks to improved surgical technique and perioperative care, extended radical surgery appears to be feasible with acceptable morbidity in chemosensitive women with Stage III cervical carcinoma and may constitute a valid alternative to radiotherapy in these patients.

Locally advanced cervical adenocarcinoma: is there a place for chemo-surgical treatment?

The increased frequency and poor prognosis of cervical adenocarcinoma call for new therapeutic strategies, especially in locally advanced disease. Combined neoadjuvant chemotherapy (NACT)-radical surgery (RS) has been investigated to assess its feasibility and the possible impact on disease outcome. Data were pooled from three consecutive trials on a total of 42 patients with FIGO Stage IB-IIA >4 cm (9), IIB (19), and IIIB (14) cervical adenocarcinomas. NACT regimens consisted of cisplatin (P), bleomycin (B) and methotrexate, high-dose PB, and P and doxorubicin combinations for one to three cycles. Responding patients underwent RS while those still ineligible for RS underwent radiotherapy. Fisher and chi squared tests were used to detect significant factors affecting response to NACT. Cox multivariate regression analysis was used to evaluate parameters affecting response and survival. Medians and life tables were computed by the method of Kaplan and Meier. Median follow-up times were 56 (17-95) and 54 months (15-92) from enrollment and RS, respectively. NACT-induced toxicity was generally mild and did not compromise RS when indicated. The 33 (79%) responders underwent laparotomy, while the 9 nonresponders received radiotherapy. RS was feasible in 29 (69%) patients. Macroscopic intraperitoneal tumor (IPT) excluded abandoning RS in 4 cases. Mild to moderate RS-related complications were seen in 41% of cases with the same pattern as in the absence of any prior treatment. In patients undergoing RS, node metastasis and microscopic IPT were detected in 2 (7%) and 3 (10%) patients, respectively. The 5-year overall and disease-free survivals were 71% (100% IB-IIA and 84% IIB vs 36% IIIB; P = 0.001) and 88%, respectively. None of the nonresponders survived (median 10 months, 6-25), compared with an 84% 5-year survival of responders (P < 0.001). FIGO stage and parametrial involvement significantly predicted response to NACT which was the only independent variable affecting survival (P = 0.006). This retrospective study provided evidence of the chemosensitivity of locally advanced cervical adenocarcinoma and that chemoresponsiveness is the most potent predictor of cure, as demonstrated in squamous cell cervical cancer. Combined NACT and RS is a feasible treatment which seems to be able to improve the outcome of Stage IB-IIB cervical adenocarcinoma. Randomized trials comparing this new strategy with conventional treatments seem to be warranted.

Lymphatic spread of cervical cancer: an anatomical and pathological study based on 225 radical hysterectomies with systematic pelvic and aortic lymphadenectomy.

To assess the patterns of lymphatic spread in cervical carcinoma, radical hysterectomy with systematic lymphadenectomy was performed in 66 patients FIGO stage IB-IIA <4 cm, and 159 patients stage IB-IIA >4 cm to stage IV. The latter patients were treated with neoadjuvant chemotherapy (NACT). Parametria were evaluated by the giant section technique in 109 patients. In 40 of these, the superficial and deep layers of the vesicouterine ligament, the sacrouterine ligament, and the distal part of the cardinal ligament were separately evaluated. The median number of nodes removed was 48 pelvic (range 20-107) and 22 aortic (range 7-64). Positive nodes were found in 14 (21%) stage IB-IIA <4 cm and in 38 (23%) NACT-treated patients, all having pelvic node metastasis. Aortic nodes were involved in 2 (3%) and 5 (3%) patients, respectively. Solitary metastases were found in the superficial obturator (21% of stage IB-IIA <4 cm and 31% of NACT-treated positive node patients, respectively), external iliac (7 and 3%, respectively), and common iliac nodes (7 and 3%, respectively). Parametrial nodes were found in 59% of giant sections (8% metastatic). The superficial and deep layers of the vesicouterine ligament, the uterosacral ligament, and the distal part of the lateral parametrium revealed the presence of nodes in 33% (no metastatic nodes), 26% (3% metastatic), 5% (no metastatic nodes), and 70% (5% metastatic) of patients, respectively. Overall, parametrial nodes were positive in 12% of stage IB-IIA <4 cm and 7% of NACT-treated patients. The diameter of node metastasis was <10 mm in more than 80% of positive nodes. In conclusion, parametrial nodes were mainly located in the cardinal and vesicouterine ligaments, both being a potential site of metastasis. The superficial obturator, external iliac, common iliac, paracaval, intercavoaortic, and paraaortic nodes were the groups more frequently involved. These data may be useful for tailoring radical hysterectomy and lymphadenectomy according to the primary tumor and the surgeon's intent.

Surgery by minilaparotomy in benign gynecologic disease.

A new, minimally invasive technique for the management of benign gynecologic disease is proposed. With the patient in a steep Trendelenburg position, access to the pelvis is gained through a minimal suprapubic incision (4-9 cm) beneath the pubic hair line. The subcutaneous fat is incised in a cranial direction and the abdominal fascia is opened 2-3 cm above the skin incision. The peritoneum is opened manually and two or three Deaver retractors replace the traditional self-retaining retractor. Continuous repositioning of the retractors permits the operative window to be focused always on the surgical field. This technique can be performed only if the following criteria are met: use of narrow and light instruments; exteriorization of the affected organs; combined, unidirectional maneuvering of all the retractors; and prompt hemostasis by electrocoagulating forceps. Among 78 inpatients with benign gynecologic diseases who underwent surgical treatment with this approach, the feasibility rate was 96% and no intraoperative complications or severe postoperative morbidity were observed. Pelvic surgery by minilaparotomy is a feasible and safe approach in the treatment of benign gynecologic disease.
