Sentinel lymph node identification and radical hysterectomy with lymphadenectomy in early stage cervical cancer: laparoscopy versus laparotomy

STUDY OBJECTIVE: To estimate the feasibility and results of sentinel lymph node identification and radical hysterectomy with pelvic lymphadenectomy entirely completed by laparoscopy versus laparotomy in early stage cervical cancer. DESIGN: Retrospective, nonrandomized clinical study (Canadian Task Force classification II-2). SETTING: Acute care, teaching hospital. PATIENTS: From September 2000 through January 2005, 50 consecutive patients with International Federation of Gynecology and Obstetrics stage IA(2), IB(1), and IIA disease less than 4 cm underwent radical hysterectomy and lymphadenectomy with intraoperative sentinel lymph node biopsy. INTERVENTIONS: The operation was performed entirely by laparoscopy in 20 patients and using the conventional abdominal approach in 30. Feasibility of sentinel lymph node identification, surgical morbidity, overall survival, and recurrence rate-free survival in both groups were compared. MEASUREMENTS AND MAIN RESULTS: The overall detection rate of the sentinel lymph node was 100% (false negative 0%). A mean of 2.50 sentinel nodes/patient was detected in the laparotomy group compared with a mean of 2.55 nodes in the laparoscopic group (p = .874). Bifurcation of the right common iliac artery was the most frequent nodal location. Blood loss and length of stay were significantly lower in the laparoscopic group, but surgical time was significantly longer. The median follow-up was 35 months (range 5-57) in the laparotomy group and 22.5 (range 2-52) in the laparoscopic group. Differences in overall survival and disease-free survival were not observed. CONCLUSION: Sentinel lymph node identification and radical hysterectomy in the initial treatment of early stage cervical cancer can be performed safely by laparoscopy with lower morbidity and overall survival and recurrence-free survival similar to standard laparotomy.     

Extended experience in the use of laparoscopic ultrasound to detect pelvic nodal metastasis in patients with cervical carcinoma

OBJECTIVE: To evaluate the use of laparoscopic ultrasound (USG) to detect pelvic nodal metastasis in patients with early stage cervical carcinoma. METHODS: Laparoscopic USG was used to search for pelvic lymph node metastasis in stage Ia2 to IIa cervical carcinoma patients before radical hysterectomy. Suspicious lymph nodes identified by laparoscopic USG were removed laparoscopically for pathological confirmation by frozen section. If nodal metastasis was diagnosed, radical hysterectomy would be cancelled but enlarged lymph nodes were removed preferably by laparoscopic approach before closing the abdomen. These patients were treated with radiotherapy after recovering from the surgery. By comparing the laparoscopic USG and pathological findings of lymph nodes removed with or without radical hysterectomy, diagnostic accuracy of laparoscopic USG was determined. RESULTS: Ninety-three patients were recruited and the final analysis included 90 patients. Laparoscopic USG found suspicious lymph nodes in 17 patients and nodal metastases were confirmed pathologically in 14 of them. Three patients with macroscopic and five patients with microscopic pelvic nodal metastases were missed by laparoscopic USG. The accuracy, sensitivity, specificity, positive and negative predictive value of laparoscopic USG in detecting pelvic lymph node metastasis were 87.8%, 63.6%, 95.6%, 82.4%, and 89%, respectively. Macroscopic metastatic nodes were successfully removed laparoscopically in 11 out of 14 patients and laparotomy was required for the other three patients. CONCLUSIONS: Laparoscopic USG can be performed with no major morbidity. This technique is sensitive in detecting macroscopic but not microscopic metastatic pelvic lymph nodes. Removal of macroscopic metastatic nodes identified via laparoscopic USG via laparoscopic approach could be accomplished in majority of patients.     

Laparoscopic sentinel lymph nodes identification followed by trachelectomy in early stage cervical cancer

The status of regional lymph nodes is the main prognostic factor in diagnosis and treatment of early stage of the cervical cancer. If the first node that drains a tumor site (sentinel node) is not metastatic, other lymph nodes should also be free of the disease. Detection using blue dye and laparoscopic removal of the sentinel lymph nodes let to avoid radical hysterectomy with pelvic limphadenectomy and it is especially useful in young women who want to preserve fertility. We describe a case of a 33- year old woman with invasive cervical cancer who underwent laparoscopic sentinel lymph nodes detection followed by trachelectomy. Thus histopatological examination confirmed no metastasis in removed sentinel lymph nodes, trachelectomy as a minimally invasive procedure was performed.

Laparoscopic identification of sentinel lymph node in treatment of invasive cervical cancer

The fundamental prognostic factor in treatment of early cervical cancer is the state of regional lymph nodes. If the first lymphatic node is involved by cancer, the other ones may be affected; otherwise if the first one is free of metastatic cells, the others should not be involved by cancer either. Detection and removal of the lymphatic node called the sentinel lymph node permit to avoid radical lymphadenectomy which is connected with many severe complications. We reported a technique of identification of the sentinel lymph node during laparoscopic radical hysterectomy with pelvic lymphadenectomy in treatment of early invasive cervical cancer with presentation of case history. Identification of sentinel node with its histopathology examination may be essential in women with cervical cancer and potentially identifies women in whom lymph node dissection can be avoided. Laparoscopic lymphadenectomy seems to be equally effective and less invasive in comparison to traditional technique.     

The role of laparoscopic lymphadenectomy in the management of cervical carcinoma.

Laparoscopic lymphadenectomy was performed on 18 patients with invasive carcinoma of the cervix prior to definitive radiation therapy and/or radical hysterectomy. Ten patients underwent pelvic and para-aortic lymphadenectomies prior to planned radiotherapy. Two of these patients had grossly positive pelvic nodes, and one had a microscopically positive para-aortic node. Eight patients with early disease were considered candidates for radical hysterectomy and underwent laparoscopic lymphadenectomy. Three of these patients were found to have positive pelvic lymph nodes and the hysterectomy was abandoned. Five patients underwent radical hysterectomies immediately following their laparoscopic procedures. The average number of lymph nodes removed laparoscopically in these patients was 31.4; the average number of additional lymph nodes resected at laparotomy with the radical hysterectomy was 2.8. A single microscopically positive parametrial lymph node was found on permanent section in 1 patient with radical hysterectomy. No significant complications were associated with the laparoscopic lymphadenectomies. Nine of the 13 patients who underwent laparoscopic procedures only were discharged on Postoperative Day 1. The ability to perform pelvic and para-aortic lymphadenectomy allows for complete surgical staging of carcinoma of the cervix laparoscopically.     

Laparoscopic-assisted vaginal versus abdominal surgery in patients with endometrial cancer--a prospective randomized trial

OBJECTIVE: We compared a laparoscopic-vaginal approach with the conventional abdominal approach for treatment of patients with endometrial cancer. METHOD: Between July 1995 and August 1999, 70 patients with endometrial cancer FIGO stage I-III were randomized to laparoscopic-assisted simple or radical vaginal hysterectomy or simple or radical abdominal hysterectomy with or without lymph node dissection. RESULTS: Thirty-seven patients were treated in the laparoscopic versus 33 patients in the laparotomy group. Lymph node dissection was performed in 25 patients by laparoscopy and in 24 patients by laparotomy. Blood loss and transfusion rates were significantly lower in the laparoscopic group. Yield of pelvic and para-aortic lymph nodes, duration of surgery, and incidence of postoperative complications were similar for both groups. Overall and recurrence-free survival did not differ significantly for both groups. CONCLUSION: The laparoscopic-vaginal approach for treatment of endometrial cancer is associated with lower perioperative morbidity compared with the conventional abdominal approach.     

Intraoperative sentinel node identification in early stage cervical cancer using a combination of radiolabeled albumin injection and isosulfan blue dye injection

OBJECTIVES: We investigated the feasibility of sentinel lymph node identification using radioisotopic lymphatic mapping with technetium-99m-labeled human serum albumin and isosulfan blue dye injection in patients undergoing radical hysterectomy with pelvic lymphadenectomy for treatment of early cervical cancer. METHODS: Between September 2000 and October 2002, 25 patients with cervical cancer FIGO stage I (n=24) or stage II (n=1) underwent sentinel lymph node detection with preoperative lymphoscintigraphy (technetium-99m colloid albumin injection around the tumor) and intraoperative lymphatic mapping with blue dye and a handheld or laparoscopic gamma probe. Complete pelvic or paraaortic lymphadenectomy was performed in all cases by open surgery or laparoscopic surgery. RESULTS: In 23 evaluable patients, a total of 51 sentinel lymph nodes were detected by lymphoscintigraphy (mean 2.21 nodes per patient). Intraoperatively, 61 sentinel lymph nodes were identified, with a mean of 2.52 nodes per patient by gamma probe and a mean of 1.94 nodes per patient after isosulfan blue injection. Forty percent of sentinel nodes were found in the interiliac region and 25% in the external iliac area. Microscopic nodal metastases (four nodes) were confirmed in 12% of cases. All these lymph nodes were previously detected as sentinel lymph nodes. The remaining 419 nodes after pelvic lymphadenectomy were histologically negative. CONCLUSIONS: Sentinel lymph node identification with technetium-99m-labeled nanocolloid combined with blue dye injection is feasible and showed a 100% negative predictive value, and potentially identified women in whom lymph node dissection can be avoided.

Maylard incision for radical hysterectomy and pelvic and para-aortic lymph node dissection

Angioli R, Koechli OR, Sevin B-U. Maylard incision for radical hysterectomy and pelvic and para-aortic lymph node dissection. Int J Gynecol Cancer 1998; 8 : 274–278.
Although the transverse, muscle-splitting technique for abdominal incision (Maylard incision) has been described for radical hysterectomy and for lymph node dissection of the pelvis and para-aortic area, the adequacy of the procedure performed through this incision has not been assessed. From 1991 to 1994, 205 patients underwent radical hysterectomy with pelvic lymph node (PLN) and para-aortic lymph node (PALN) dissection at the Division of Gynecologic Oncology, Jackson Memorial Hospital/University of Miami School of Medicine. Twenty-four patients with cervical cancer stage IB-IIA underwent radical hysterectomy, pelvic lymph node and para-aortic lymph node dissection through a Maylard incision. Three patients had panniculectomy performed at the same time. Duration of surgery, estimated blood loss, number of pelvic and para-aortic lymph nodes removed and duration of hospital stay were within acceptable ranges. Postoperative and intraoperative complications were minimal. Excellent cosmetic results were obtained. In conclusion, the Maylard incision offers good exposure to the pelvic and para-aortic area for lymph node dissection, good cosmetic result, and can be performed in association with abdominoplasty. Complications are similar to those observed with a vertical skin incision. This type of incision should be considered in selected young patients with early cervical cancer and in obese patients desiring abdominoplasty.     

Number and distribution of pelvic lymph nodes and effect of surgical pathologic factors on pelvic lymph node status in patients with early-stage cervical carcinoma treated with radical hysterectomy and pelvic lymph node dissection

PURPOSE OF INVESTIGATION: To report the number and distribution of pelvic lymph nodes and to identify surgical pathologic factors that best predict positive pelvic lymph nodes in patients with early-stage cervical carcinoma treated with radical hysterectomy and pelvic lymph node dissection (RHND). METHODS: Data from the files of 126 patients with cervical carcinoma treated by RHND at the Soroka Medical Center from 1962 through 2005 were analyzed. RESULTS: The status of pelvic lymph nodes was known in 114 patients. The exact number of lymph nodes removed from the pelvis of each patient was known in 111 patients. The mean number of lymph nodes removed from the pelvis per patient was 26.6 (median 23; range 1-62). Positive pelvic lymph nodes were found in 35 (30.7%) of the patients with a mean of 3.4 (median 2; range, 1-15) positive pelvic lymph nodes per patient. In a univariate analysis, positive lymph vascular space invasion and positive parametrial and/or paracervical involvement were significant predictors of positive pelvic lymph nodes, whereas penetration > or = 50% of the thickness of the cervical wall and grade 2+3 were of borderline significance. In a multivariate analysis, positive lymph vascular space invasion was the strongest and the only significant predictor of positive pelvic lymph nodes, whereas positive parametrial and/or paracervical involvement was of borderline significance. CONCLUSIONS: In patients with early-stage cervical carcinoma treated with RHND, positive lymph vascular space invasion emerged to be the strongest and most significant predictor of positive pelvic lymph nodes.     

Laparoscopic port-site recurrence following surgery for a stage IB squamous cell carcinoma of the cervix with negative lymph nodes

BACKGROUND: Port-site metastases are commonly reported after laparoscopic surgery for ovarian cancer, but have also been reported in patients with cervical or endometrial cancer with positive lymph nodes. Recently, a case of port-site recurrence after laparoscopic surgery for a patient with node-negative early-stage adenocarcinoma of the cervix was reported. We report the first case of port-site metastasis in a patient with stage IB squamous cell carcinoma of the cervix with negative lymph nodes. CASE: A 31-year-old woman had a laparoscopy for pelvic pain. Under anesthesia, she was noted to have a grossly abnormal-looking cervix and a biopsy revealed squamous cell carcinoma. She was referred to a gynecological oncologist and underwent radical hysterectomy and pelvic lymph node dissection through a transverse lower abdominal incision 6 weeks later. Nineteen months postoperatively, she presented with a soft tissue mass in a suprapubic laparoscopic trocar site. CONCLUSION: It is postulated that cells dislodged at the time of cervical manipulation and biopsy may have passed through the fallopian tubes and implanted in the laparoscopic port site due to the "chimney effect" caused by the pneumoperitoneum.

Total laparoscopic radical hysterectomy with intraoperative sentinel node identification in patients with early invasive cervical cancer

OBJECTIVES: To describe the feasibility and results of total laparoscopic radical hysterectomy with intraoperative sentinel lymph node identification in patients with early cervical cancer. METHODS: Between March 2001 and October 2003, 12 patients with FIGO stage IA(2) (n = 1) or IB(1) (n = 11) cancer of the cervix underwent surgical treatment through the laparoscopic route. All patients underwent a laparoscopic sentinel node identification with preoperative lymphoscintigraphy (technetium-99 m colloid albumin injection around the tumor) and intraoperative lymphatic mapping with isosulfan blue dye and a laparoscopic gamma probe followed by systematic bilateral pelvic lymphadenectomy and laparoscopic type II (n = 5) or type III (n = 7) hysterectomy. RESULTS: A mean of 2.5 sentinel nodes per patient (range 1-4) was detected, with a mean of 2.33 nodes per patient by gamma probe and a mean of 2 per patient after blue injection (combined detection rate 100%). The most frequent localization of the nodes was the interiliac region. Histopathologic examination of sentinel nodes including cytokeratin immunohistochemical analysis did not show metastasis. Microscopic nodal metastases were not found. The mean number of resected pelvic nodes was 18.6 per patient (range 10-28). The operation was performed entirely by laparoscopy in all patients and no case of laparotomy conversion was recorded. The mean duration of operation was 271 min (range 235-300), with a mean blood loss of 445 mL (range 240-800), and a mean length of stay of 5.25 days (range 3-10). No major intraoperative complications occurred. After a median follow-up of 20 months (range 5-34), all patients are free of disease. CONCLUSIONS: This study shows the feasibility of the combination of laparoscopic intraoperative sentinel node mapping and laparoscopic radical surgery in the context of minimally invasive surgery for the management of patients with early cervical cancer.     

Sentinel node detection in cervical cancer with (99m)Tc-phytate

OBJECTIVES: The aim of this study was to investigate the feasibility of sentinel lymph node (SLN) identification using radioisotopic lymphatic mapping with technetium-99 m-labeled phytate in patients undergoing radical hysterectomy with pelvic lymphadenectomy for treatment of early cervical cancer. METHODS: Between July 2001 and February 2003, 56 patients with cervical cancer FIGO stage I (n = 53) or stage II (n = 3) underwent sentinel lymph node detection with preoperative lymphoscintigraphy ((99m)Tc-labeled phytate injected into the uterine cervix, at 3, 6, 9, and 12 o'clock, at a dose of 55-74 MBq in a volume of 0.8 ml) and intraoperative lymphatic mapping with a handheld gamma probe. Radical hysterectomy was aborted in three cases because parametrial invasion was found intraoperatively and we performed only sentinel node resection. The remaining 53 patients underwent radical hysterectomy with complete pelvic lymphadenectomy. Sentinel nodes were detected using a handheld gamma-probe and removed for pathological assessment during the abdominal radical hysterectomy and pelvic lymphadenectomy. RESULTS: One or more sentinel nodes were detected in 52 out of 56 eligible patients (92.8%). A total of 120 SLNs were detected by lymphoscintigraphy (mean 2.27 nodes per patient) and intraoperatively by gamma probe. Forty-four percent of SLNs were found in the external iliac area, 39% in the obturator region, 8.3% in interiliac region, and 6.7% in the common iliac area. Unilateral sentinel nodes were found in thirty-one patients (59%). The remaining 21 patients (41%) had bilateral sentinel nodes. Microscopic nodal metastases were confirmed in 17 (32%) cases. In 10 of these patients, only SLNs had metastases. The 98 sentinel nodes that were negative on hematoxylin and eosin were submitted to cytokeratin immunohistochemical analysis. Five (5.1%) micrometastases were identified with this technique. The sensitivity of the sentinel node was 82.3% (CI 95% = 56.6-96.2) and the negative predictive value was 92.1% (CI 95% = 78.6-98.3). The accuracy of sentinel node in predicting the lymph node status was 94.2%. CONCLUSION: Preoperative lymphoscintigraphy and intraoperative lymphatic mapping with (99m)Tc-labeled phytate are effective in identifying sentinel nodes in patients undergoing radical hysterectomy and to select women in whom lymph node dissection can be avoided.     

Sentinel node detection with radiocolloid lymphatic mapping in early invasive cervical cancer

We assessed the feasibility of sentinel lymph node detection using technicium-99 radiocolloid lymphatic mapping for predicting lymph node metastases in early invasive cervical cancer. Thirty patients with cervical cancer (stages IA2-IIA) underwent preoperative lymphoscintigraphy using technicium-99 intracervical injection and intraoperative lymphatic mapping with a handheld gamma probe. After dissection of the sentinel nodes, the standard procedure of pelvic lymph node dissection and radical hysterectomy was performed as usual. The sentinel node detection rate was 100% (30/30). There were seven (23.3%) cases of microscopic lymph node metastases on pathologic analysis. All of them had sentinel node involvement. Therefore, the sensitivity of sentinel node identification for prediction of lymph node metastases was 100%, and no false negative was found. Preoperative lymphoscintigraphy, coupled with intraoperative lymphatic mapping, located the sentinel nodes accurately in our study patients. This sentinel node detection method appears to be feasible for predicting lymph node metastases.     

Laparoscopic retroperitoneal lymphadenectomy followed by immediate laparotomy in women with cervical cancer: a gynecologic oncology group study

OBJECTIVES: From May 1993 until June 1997, the Gynecologic Oncology Group undertook a study of women with cancer of the cervix (Stage IA, IB, and IIA) who were about to undergo radical abdominal hysterectomy, pelvic lymphadenectomy, and aortic lymph node sampling. Immediately before this surgery, laparoscopy was performed and removal of the lymph nodes was attempted. There were two objectives: (1) to obtain information on the adverse effects and difficulties associated with laparoscopic lymph node removal and (2) to determine the adequacy of the lymph node removal. METHODS: Four methods determined the adequacy of the lymph node removal: (1) the surgeon's opinion during laparoscopy, (2) a photographic record reviewed by two independent observers, (3) inspection of the surgical sites at laparotomy, and (4) lymph node count. RESULTS: Seventy-three women were entered onto the study. Four patients were judged ineligible; 2 did not undergo laparoscopy and 17 women did not complete laparoscopic surgery because of metastatic lymph nodes judged unresectable or complications. Ten women were inevaluable. The remaining 40 women were completely evaluable for protocol objectives. All cases of bilateral laparoscopic aortic lymph node sampling were judged adequate by all four methods of evaluation. For laparoscopic pelvic lymphadenectomy 6 were judged incomplete at laparotomy, 3 of which were judged incomplete by independent reviewers. The mean number of right pelvic nodes removed was 16.6; left pelvic nodes 15.5; right aortic nodes 6.2; and left aortic nodes 5.9. CONCLUSIONS: Laparoscopic bilateral aortic lymph node sampling appeared to be reasonably safe and feasible. Laparoscopic therapeutic bilateral pelvic lymphadenectomy, although having a reasonable complication rate, demonstrated problems regarding adequacy, which are probably correctable.

目的 探索子宫颈癌根治术中淋巴显影和前哨淋巴结识别的方法及其可行性,评价前哨淋巴结预测盆腔淋巴结有无肿瘤转移的准确性。方法 应用染料法对20例宫颈癌患者(临床分期为Ib期3例、Ⅱa期12例、Ⅱb期5例)在根治术中于宫颈肿瘤周围的正常组织中分4点(3、6、9、12点处)注入美蓝或专利蓝溶液4ml,识别和定位蓝染的淋巴结(即前哨淋巴结),然后再按常规行盆腔淋巴清扫术,所有淋巴结一起送病理检查。结果 20例宫颈癌患者中淋巴管有蓝色染料摄取者18例,共有蓝染淋巴结33枚,其中左侧15枚,右侧18枚,前哨淋巴结识别成功14例,识别率为78％(14／18)。共有6例有淋巴结转移,淋巴结转移率为33％(6／18)。成功识别前哨淋巴结的14例中,淋巴结转移5例,其中前哨淋巴结和盆腔淋巴结均转移者2例,仅有前哨淋巴结转移者3例,准确性为100％,假阴性率为0。结论 宫颈癌根治术中淋巴显影和前哨淋巴结识别技术是可行的,但识别率尚有待提高。     

Surgical pathologic factors in patients with early-stage cervical carcinoma treated with radical hysterectomy and pelvic lymph node dissection: association with administration of adjuvant radiotherapy and effect on survival

PURPOSE OF INVESTIGATION: To identify surgical pathologic factors that best correlate with administration of adjuvant radiotherapy and best predict survival in early-stage cervical carcinoma treated with radical hysterectomy and pelvic lymph node dissection (RHND). METHODS: Data from the files of 126 patients with cervical carcinoma treated by RHND at the Soroka Medical Center from 1962 through 2005 were analyzed. RESULTS: Fifty-four percent of the patients received postoperative adjuvant radiotherapy. In a univariate analysis, each of the following factors: positive pelvic lymph nodes, lower uterine segment involvement, lymph vascular space involvement, penetration > or = 50% of the cervical wall, grade 2+3, parametrial and/or paracervical involvement, vaginal margin involvement, non-squamous histologic type, tumor size > or = 3 cm and Stage IB2 + IIA was significantly associated with administration of radiotherapy. In a multivariate analysis, positiviy of pelvic lymph nodes was persistently the most significant factor associated with administration of radiotherapy. The 5-year survival rate was 82.6% overall. In a univariate analysis, a significant worsening in survival was demonstrated with positivity of pelvic lymph nodes and positivity of lymph vascular space involvement. In a "better fit" model of multivariate analysis, pelvic lymph node status was the strongest and the only significant predictor of survival. CONCLUSIONS: In patients with early-stage cervical carcinoma treated with radical hysterectomy and pelvic lymph node dissection, pelvic lymph node status is the strongest factor affecting administration of adjuvant radiotherapy and the most significant predictor of survival.
