Role of sentinel lymph node biopsy procedure in cervical cancer: a critical point of view.

OBJECTIVE: To report our experience about the role of sentinel node biopsy in cervical cancer patients while debating provocatory arguments concerning this procedure. METHODS: From June 2001 to February 2003, patients affected by stage IB(1) cervical cancer were submitted to the sentinel node biopsy procedure. Patients were submitted to lymphoscintigraphy and, subsequently, to laparoscopy in order to locate the sentinel lymph node. RESULTS: Thirty-seven patients were enrolled in the study. Sentinel node(s) was(were) identified with preoperative lymphoscintigraphy in 89% of the patients. Intraoperative detection rate was 70%. During surgery in 31% of the patients, sentinel node was detected bilaterally; in 15%, two sentinel nodes on the same side of the lymphatic vessels were detected. The sentinel node was located at the level of superficial common iliac vessels (26%), external iliac vessels (69%), and superficial obturator vessels (49%). In 77% of the patients, the histologic specimen sent by the surgeon as unique sentinel node contained two or more nodes. Metastatic sentinel nodes were found in 23% of the patients. There was no case with a positive nonsentinel node in the presence of a negative sentinel node. CONCLUSION: Sentinel node detection is a feasible procedure in cervical cancer patients. However, a high percentage of patients is found with bilateral and/or more than one sentinel lymph node. Improvements in detection rate and pathological analysis are needed prior to consider the sentinel node biopsy a routine procedure in cervical cancer patients.

Tailoring the parametrectomy in stages IA2-IB1 cervical carcinoma: is it feasible and safe?

OBJECTIVE: Several authors have proposed the use of a less aggressive surgery (i.e., modified or type 2 radical hysterectomy) for patients affected by early stages cervical carcinoma. However, little attention has been given to the evaluation of adverse prognostic factors before selecting the surgical approach. The aim of this study is to evaluate the feasibility and safety of tailoring parametrectomy on the basis of specific prognostic factors preoperatively assessed. METHODS: Patients with cervical carcinoma FIGO IA2-IB1 entered the study. Eligibility criteria were: age < 75 years, no contraindications for surgery, informed consent, expected cooperation for follow-up. Tumor size was preoperatively assessed by pelvic examination under anesthesia and pelvic MRI. Patients were submitted to systematic lymphadenectomy of superficial obturator, external iliac, and interiliac nodes by laparotomy or laparoscopy. Lymph nodes were sent for frozen section. Node-negative patients were submitted to modified radical hysterectomy (type 2). Patients with nodal metastases underwent classical radical hysterectomy (types 3-4) and systematic pelvic and aortic node dissection up to the inferior mesenteric artery. Survival rates were calculated using the Kaplan-Meier product-limit method. RESULTS: Eighty-three patients were enrolled in the study. Among these, 63 patients were node-negative at frozen section, and therefore submitted to modified radical hysterectomy (Group A); 20 patients were found having nodal metastases intra-operatively, and therefore submitted to classical radical hysterectomy (Group B). Median follow up was 30 months. Five years overall survival was 95% for Group A, and 74% for Group B. CONCLUSIONS: Pre-treatment evaluation of adverse prognostic factors in patients affected by cervical cancer FIGO stages IA2-IB1 is feasible and mandatory to determine if a less radical surgery is applicable and safe.

Transurethral polydimethylsiloxane implantation: a valid option for the treatment of stress urinary incontinence due to intrinsic sphincter deficiency without urethral hypermobility.

PURPOSE: In this study we evaluated the 5-year followup results of periurethral polydimethylsiloxane (PDMS) injection for female stress urinary incontinence (SUI) secondary to intrinsic sphincter deficiency (ISD) without hypermobility of the vesicourethral junction. MATERIALS AND METHODS: A total of 61 female patients with ISD were enrolled in this prospective, observational study. Preoperative and postoperative assessment included a standardized urogynecologic history with questions regarding urinary function, urogynecologic and neurological physical examination, and urodynamic assessment. All patients underwent periurethral PDMS injection. Patient followup was performed 1, 6, 12, 24, 36, 48 and 60 months after surgery. RESULTS: At 60 months after injection the SUI cure rate was 18%, the improvement rate was 39% and the failure rate was 43%. The success rate was 57%. Of the patients 45 (74%) subjectively improved with respect to the severity of urinary incontinence. No postoperative early complications were found. At 60 months of followup only minor complications were reported (11%). CONCLUSIONS: Careful patient selection by optimal diagnostic tools are essential for maximizing the results of urethral bulking agent therapy. PDMS injection in women with SUI due to ISD with limited urethral mobility is a valid, minimally invasive procedure.

Long-term bladder function in patients with locally advanced cervical carcinoma treated with neoadjuvant chemotherapy and type 3-4 radical hysterectomy.

BACKGROUND: The objective of the current study was to evaluate the incidence of long-term bladder dysfunction after type 3-4 radical hysterectomy in patients with locally advanced cervical carcinoma treated with neoadjuvant chemotherapy (NACT). METHODS: A case-control study was conducted to evaluate the occurrence of long-term bladder dysfunction in 76 patients with International Federation of Gynecology and Obstetrics Stage IB-IIA (> 4 cm), Stage IIB, and Stage III cervical carcinoma who underwent type 3-4 radical hysterectomy after NACT. Preoperative assessment included acquisition of a standardized urogynecologic history, evaluation of severity of urinary incontinence symptoms, maintenance of a 3-day voiding diary, pelvic examination, urogynecologic physical examination, urodynamic assessment, and estimation of hydronephrosis. Follow-up was carried out at least 12 months after surgery. RESULTS: Urinary symptoms (sensory loss, difficult micturition, severe urinary incontinence) were reported by 20 patients (26%). Eighteen patients (24%) had a normal urodynamic profile, 16 patients (21%) had detrusor overactivity, 22 patients (29%) had urodynamic stress incontinence, 2 patients (2%) had aconctractile detrusor, and 18 patients (24%) had mixed urinary incontinence. The length of vagina removed was significantly greater among patients who had detrusor overactivity and mixed urinary incontinence compared with patients who had a normal diagnosis. CONCLUSIONS: The observed rate of bladder dysfunction was higher than the corresponding rate reported in the literature (76%). Three main disturbances were found: detrusor overactivity (21%), mixed urinary incontinence (24%), and de novo stress incontinence (21%). Detrusor overactivity was related to a prevalence of hypertonic bladder. Among patients who underwent type 4 radical hysterectomy, the extent of caudal resection of rectovaginal ligaments and vaginal tissue was found to be more strongly associated with bladder dysfunction than was the extent of lateral parametrial resection. Despite the fact that 76% of patients had abnormal urodynamic parameters, most patients were satisfied with their voiding condition.

Ultrasonographic evaluation of postoperative ovarian cyst formation after laparoscopic excision of endometriomas.

STUDY OBJECTIVE: To evaluate, by means of serial transvaginal ultrasound (US) examinations, the ovary after laparoscopic excision of endometriomas with the stripping technique. DESIGN: Prospective, controlled, single-blind clinical trial (Canadian Task Force classification II-1). SETTING: Tertiary care university hospital. PATIENTS: Forty-seven patients, from 21- to 35-years old, undergoing laparoscopic excision of a monolateral ovarian endometrioma. INTERVENTION: The patients underwent serial US scans performed by a blinded observer during the first, third, and sixth menstrual cycle after surgery. MEASUREMENTS AND MAIN RESULTS: At the first follow-up US examination, an abnormal finding, namely the presence of an ovarian cyst on the operated ovary, was diagnosed in five of 47 patients (10.6%; p = .03 when compared with the nonoperated ovary). In the remaining 42 patients (89.4%), no gross abnormalities were evident. No differences were present between the two ovaries as to ovarian volume or follicular development pattern. During the third follow-up US, in 47 patients (100%) no gross abnormalities were present. CONCLUSION: The US follow-up of ovaries operated on for endometriomas by laparoscopy demonstrates that the evidence of an ovarian cyst in the early postoperative period is not an uncommon event. This finding, occurring in approximately 10% of cases, seems to be a transient one occurring during ovarian healing after surgery, since no evidence of such anomaly was present on subsequent US scans. Therefore, treatment for US evidence of recurrence of an ovarian endometrioma should be deferred for at least 3 to 6 months if the diagnosis of recurrence is made in the early postoperative period. Apart from this finding, the operated ovary is indistinguishable from the contralateral one, even 1 month after surgery.

Guidelines of how to manage vesicovaginal fistula.

Vesicovaginal fistulas are among the most distressing complications of gynecologic and obstetric procedures. The risk of developing vesicovaginal fistula is more than 1% after radical surgery and radiotherapy for gynecologic malignancies. Management of these fistulas has been better defined and standardized over the last decade. We describe in this paper the success rate reported in the literature by treatment modality and the guidelines used at our teaching hospitals, University of Rome Campus Biomedico and University of Miami School of Medicine. In general, our preferred approach is a trans-vaginal repair. To the performance of the surgical treatment, we recommend a minimum of a 4-6 week's wait from the onset of the fistula. The vaginal repair techniques can be categorized as to those that are modifications of the Latzko procedure or a layered closure with or without a Martius flap. The most frequently used abdominal approaches are the bivalve technique or the fistula excision. Radiated fistulas usually require a more individualized management and complex surgical procedures. The rate of successful fistula repair reported in the literature varies between 70 and 100% in non-radiated patients, with similar results when a vaginal or abdominal approach is performed, the mean success rates being 91 and 97%, respectively. Fistulas in radiated patients are less frequently repaired and the success rate varies between 40 and 100%. In this setting many institutions prefer to perform a urinary diversion. In conclusion, the vaginal approach of vesicovaginal fistulas repair should be the preferred one. Transvaginal repairs achieve comparable success rates, while minimizing operative complications, hospital stay, blood loss, and post surgical pain. We recommend waiting at least 4-6 weeks prior to attempting repair of a vesicovaginal fistula. It is acceptable to repeat the repair through a vaginal approach even after a first vaginal approach failure. In the more individualized management of fistulas associated with radiation, the vaginal approach should still be considered.

Modulation of surgery in early invasive cervical cancer.

In modern oncology increasing attention is given to patient quality of life issues. Reduction of morbidity and preservation of reproductive organs are aspects of major concern for surgeons treating women affected by gynecologic tumors. To achieve these goals both improvements of surgical technique and peri-operative management, but mainly a better individualization of therapy are needed. This requires: (1) advanced knowledge of the natural history of disease, (2) accurate pathological evaluation, (3) innovative diagnostic tools. In the last decades remarkable progresses have been made in these fields making modulation of surgery a concrete option in the treatment of early invasive cervical cancer. Currently, tumor volume measurements by step serial section of cone specimen (stage IA(2) and small volume IB(1)), sentinel nodal group lymphadenectomy and sentinel node biopsy (stage IB(1)) represent the best techniques available for assessing the risk of extracervical spread of disease allowing tailoring of patient management to optimize the patients outcome and quality of life.

Vesical dysfunctions after radical hysterectomy for cervical cancer: a critical review.

Functional disorders of the lower urinary tract are the most common long-term complications following radical surgery for cancer of the uterine cervix (8-80%). These disturbances were associated to the partial interruption of the autonomic fibers innervating the bladder during the resection of anterior, lateral and posterior parametrium and vaginal cuff. The pathophysiology of these changes is actually debated. The nature of the surgical damage appears to be a decentralization rather than a complete denervation and bladder dysfunctions may be either the unmasking of intrinsic detrusor activity, characterized by a loss of beta-adrenergic innervation and a consequent alfa-adrenergic hyperinnervation or the influence of remaining sympathetic innervation. No data on long-term bladder function in patients who underwent class 4 radical hysterectomy have been reported. In our experience on long-term vesical function in 38 patients with locally advanced cervical cancer treated with neoadjuvant chemotherapy and 4 Piver type radical hysterectomy, urinary symptoms were reported in 11 patients (29%), while a normal urodynamic finding was recorded in only nine patients (24%). The most common bladder dysfunction was the storage dysfunction (47%). The voiding dysfunction was present in one patient (3%) and stress urinary incontinence in 20 patients (53%). The parametrial and vaginal resections were compared among the urodynamic diagnosis The size of lateral parametria measured on the giant sections did not differ among the groups of urodynamic diagnosis, while the length of vagina removed was significantly longer in patients with detrusor dysfunctions (storage and voiding dysfunctions) than in patients with normal diagnosis or genuine stress incontinence.

Continent urinary diversion and low colorectal anastomosis after pelvic exenteration. Quality of life and complication risk.

INTRODUCTION: Pelvic exenteration is one of the most destructive gynecologic operations performed on an elective basis, with consequent detrimental effects on the quality of life. The use of reconstructive surgery has significantly improved the quality of life of women undergoing this type of procedure. In this paper we review our experience with continent urinary diversion (Miami Pouch) and low colorectal anastomosis at the Division of Gynecologic Oncology of the University of Miami. METHODS: Patients who underwent creation of the continent urinary diversion Miami Pouch from 1988 to 1997 and supralevator pelvic exenteration with low colorectal resection and primary anastomosis from 1990 to 1997 have been included in this study. Management of complications, with particular emphasis on the conservative treatment, has been reviewed in detail for each patient. Open surgery and conservative treatment have been compared. Analysis of complications in irradiated and nonirradiated patients was performed. RESULTS: 77 patients who underwent creation of the Miami Pouch entered this study. Forty patients underwent total pelvic exenteration, and 37 patients underwent posterior exenteration. The most common urinary complications were ureteral stricture/obstruction (22.1%), difficult catheterisation (19.5%) and pyelonephritis (16.9%). Conservative management strategies were successfully used in 80% of the complications. Analysis of breakdown and fistula formation after low colorectal anastomosis was performed on 77 patients. Thirty-five percent of the irradiated patients developed anastomotic breakdown or fistulas, while the occurrence of this type of complications was only 7.5% in the nonirradiated group. CONCLUSIONS: Reconstructive procedures after pelvic exenteration present a significant risk of complications, especially in irradiated patients. Most of the complications related to the creation of continent urinary diversion can safely be treated conservatively. Low colorectal anastomosis carries an acceptable risk of complications in nonirradiated patients, but the risk in irradiated patients is very high, therefore, detailed patient selection and extensive counselling in these groups of patients is mandatory.

Bowel preparation for gynecological surgery.

Bowel preparation is an established practice before abdominal surgery. Most surgeons would use both antibiotic prophylaxis and mechanical bowel preparation (MBP) before bowel surgery. In the literature, however, there is no evidence to support the use of MBP before elective colorectal surgery. Some randomized studies and a meta-analysis report a significantly higher incidence of wound infection in patients receiving MBP versus no bowel preparation. As to gynecological surgery, data are scanty, and there is a single randomized study reporting no advantage of MBP over no bowel preparation. Based on these evidences, the routine use of MBP should be reconsidered both in general and gynecological surgery.

Subcutaneous drainage versus no drainage after minilaparotomy in gynecologic benign conditions: a randomized study.

OBJECTIVE: The purpose of this study was to determine the outcomes of subcutaneous drainage in patients who are affected by benign gynecologic diseases that are treated by a Kustner's minilaparotomy incision. STUDY DESIGN: We performed a randomized controlled study with 72 patients who underwent operation for benign gynecologic disease. Patients were assigned intraoperatively to two groups: group A (36 patients) had a closed drainage system and group B (36 patients) had no drainage. Historic data, clinical and surgical characteristics, and perioperative complications were recorded prospectively. Postoperative care data, surgical incision complications, and hospital stay were analyzed. Patients were to be seen 4 weeks after the operation to assess wound healing. RESULTS: No patients had intraoperative complications or blood transfusions. A significant difference was observed between the drainage versus no-drainage groups regarding postoperative complications and hospital stay (P =.001, both groups). No patients had surgical complications at 4 weeks after the last operation. CONCLUSION: Our data suggest that routine prophylactic subcutaneous drainage is indicated in patients who undergo Kustner's minilaparotomy incision for benign gynecologic operation. Drains significantly prevent wound complications and reduce hospital stay.

Radical vaginal trachelectomy after supracervical hysterectomy.

BACKGROUND: Radical vaginal trachelectomy (RVT) is an acceptable approach when applied toward a select group of patients with early stage cervical carcinoma. It is less invasive, can maintain fertility, and can be ideal in patients with significant comorbid factors compared to abdominal approaches. A small subset of patients with a previous supracervical hysterectomy can pose a surgical dilemma. CASE: An 81-year-old woman with a history of severe cardiac disease on routine gynecological examination was found to have adenocarcinoma in situ with a focus suspicious for invasion of the cervical stump diagnosed by cone biopsy. She previously had a supracervical hysterectomy for benign disease of the uterus. A RVT was performed as definitive treatment and the patient recovered without complications. CONCLUSION: In the rare case that presents with a history of supracervical hysterectomy, RVT with some technical modifications can still be considered as a therapeutic option for early stage cervical carcinoma.

Skin relapse from cervical cancer.

BACKGROUND: Cutaneous lymphangitis carcinomatosis from cervical carcinoma is a very rare form of tumor metastatization; only anecdotal cases are reported in the literature. Most of the patients with skin relapse experienced metastasis as a single or multiple nodules. CASE: A case of cutaneous lymphangitis carcinomatosis mimicking contact dermatitis was diagnosed at our institution in a patient affected by cervical carcinoma stage IIB. Palliative chemotherapy with paclitaxel was started and the patient experienced complete clinical response. The hypothetical mechanism of spread and the unusual manifestation of relapse are described. CONCLUSION: In a woman with a history of cervical cancer, a diffuse pruritic skin eruption should alert the clinician to the possibility of cutaneous carcinomatous lymphangitis. If a lymphangitis carcinomatosis is diagnosed, systemic intravenous chemotherapy should be considered.

Role of lymphadenectomy in ovarian cancer.

The exact role of lymphadenectomy in the management of ovarian cancer has been the object of controversy during recent years. The International Federation of Obstetrics and Gynecology has indicated that pelvic and para-aortic lymph node sampling is an integral part of the staging system of ovarian cancer. On the other hand the advantage of systematic sampling, resection of bulky nodes only, or no lymphadenectomy in terms of recurrence rate and survival of ovarian cancer patients has not yet been clearly defined. Thanks to the analysis of clinical studies on systematic lymphadenectomy, detailed anatomical studies to assess the location of lymph nodes and lymphatic spread have been recently reported. In this chapter we report the available data on clinical anatomy and pathological assessment of lymph node and lymphatic spread of ovarian cancer metastasis; we also review the clinical data on correlation of lymph node metastasis and disease status. Surgical techniques developed during years of dedication to this procedure are also described. Finally, we review and discuss the actual benefits of lymph node dissection in patients with ovarian cancer, analysing previously reported and ongoing trials.
