Comparison of midline and Pfannenstiel incision for radical hysterectomy with pelvic and paraaortic lymphadenectomy in cervical carcinoma

AIM: To compare Pfannenstiel and midline incisions with respect to efficacy and early postoperative surgical site complications in patients with early stage cervical carcinoma. METHODS: Patients with cervical carcinoma who underwent radical hysterectomy during 1995-2004 are retrospectively reviewed. There were 40 patients in the Pfannenstiel group and 71 patients in the midline group. Patients' age, type of incision, operative time, hospitalization length, postoperative surgical site complications, pre and postoperative Hb levels, number of extracted pelvic and paraaortic lymph nodes were the variables collected from the patients' files and oncology follow-up forms. RESULTS: Mean age (53.5+/-6.96 vs 55.9+/-10.5, P=0.2) and preoperative Hb levels of patients (12.52+/-1.48 vs 12.94+/-1.34, P=0.17) were not statistically different in midline and Pfannenstiel groups, respectively. Operative time (141.8+/-36 vs 135.8+/-31 min), number of extracted lymph nodes in pelvic (23.05+/-9.7 vs 23.5+/-8.07) and paraaortic areas (3.17+/-1.68 vs 2.66+/-1.15) were not significantly different among the midline and Pfannenstiel groups, respectively (P>0.05). Although postoperative incisional complications were more common in the midline group, this difference did not reach a significant level (11.3% vs 7.5%, P=0.52). Duration of hospitalization was not significantly different between the midline and Pfannenstiel groups, respectively (6.3+/-2.69 vs 6.2+/-2.72 days, P=0.21). Multivariate analysis revealed postoperative Hb levels to be significantly different among the groups (P=0.017, OR=1.59, 95% CI: 1.08-2.35). CONCLUSION: Pfannenstiel incision can be used for radical hysterectomy with pelvic and paraaortic lymphadenectomy in selected patients with cervical carcinoma, without any negative influence on optimal resectability of tumor and surgical morbidity.     

Evaluation of the Pfannenstiel incision for radical abdominal hysterectomy with pelvic and para-aortic lymphadenectomy

Abstract. Mendez LE, Cantuaria G, Angioli R, Mirhashemi R, Gabriel C, Estape R, Penalver M. Evaluation of the Pfannenstiel incision for radical abdominal hysterectomy with pelvic and para-aortic lymphandenectomy.
Radical abdominal hysterectomy with pelvic and para-aortic lymphadenectomy (RAH/P + PAL) has classically been described through a low midline vertical incision. Transverse incisions have been used with good results for various pelvic surgical procedures. Hesitancy has been encountered when utilizing these transverse incisions in gynecologic oncology patients. In most studies, muscle-splitting transverse incisions seem to be of equal efficacy as midline vertical incisions in regards to surgical exposure and clinicopathologic data obtained and are known to be superior in cosmesis and postoperative morbidity. A retrospective chart review was performed to identify 25 patients who underwent RAH/P + PAL for stage I carcinoma of the cervix from 1990 to 1998 through a nonmuscle splitting (Pfannenstiel) abdominal incision. All patients were seen and had follow-up in the Division of Gynecologic Oncology, University of Miami School of Medicine/Jackson Memorial Medical Center (Miami, FL). Data were collected on various clinical and surgical parameters including height/weight, operative time, blood loss, number of lymph nodes obtained, length of hospital stay, and postoperative complications. Analysis of the data revealed that operative time and average blood loss were within acceptable parameters. The yield at lymphadenectomy for pelvic and para-aortic lymph nodes was also respectable. Postoperative complications were minimal and there were no wound complications reported. Therefore, the Pfannenstiel incision can be safely utilized in a select group of patients undergoing RAH/P + PAL.     

Chylous ascites following operation for para-aortic lymph node dissection in a patient with cervical cancer

Abstract.   Takeuchi S, Kinoshita H, Terasawa K, Minami S. Chylous ascites following operation for para-aortic lymph node dissection in patient with cervical cancer. Int J Gynecol Cancer 2006; 16(Suppl. 1): 418–422.
This is a case report of chylous ascites caused by performing para-aortic lymph node dissection for a patient with cervical cancer. Postoperative chylous ascites is a rare condition that usually develops as a result of operative trauma to the thoracic duct, cisterna chyli, or their major tributaries. It has mainly occurred in thoracic operations, and chylous ascites has rarely been reported in gynecologic surgery. It is associated with serious nutritional and immunologic consequences due to the constant loss of protein and lymphocytes. Treatment that comprises conservative and surgical procedures is selected based on disease severity. We experienced massive chylous ascites after para-aortic surgery and successfully managed it conservatively with dietary intervention and parenteral nutrition.     

Analysis of clinicopathologic factors predicting para-aortic lymph node metastasis in endometrial cancer

The purposes of this study were to compare the relationships between para-aortic lymph node metastasis and various clinicopathologic factors to evaluate whether para-aortic lymph node dissection is necessary when treating endometrial cancer. A retrospective study was performed on 841 patients with endometrial cancer, who underwent the initial surgery at the Keio University Hospital. Clinicopathologic factors related to para-aortic lymph node metastasis significant on a univariate analysis were analyzed in a multivariate fashion using a logistic model. According to the multivariate analysis, the clinicopathologic factor most strongly related to the existence of para-aortic lymph node metastasis was positive pelvic lymph node metastasis (P < 0.01). Among the 155 patients who underwent pelvic and para-aortic lymph node dissection, the difference of 5-year overall survival by the presence of retroperitoneal lymph node metastasis was examined by Kaplan-Meier method. The prognosis was poor even if para-aortic lymph node dissection was performed in cases of positive para-aortic lymph node metastasis. In conclusion, when deciding whether to perform para-aortic lymph node dissection in patients with endometrial cancer, it is necessary to consider the pelvic lymph nodal status. If there is no pelvic lymph node metastasis, it could not be necessary to perform para-aortic lymph node dissection.

目的:探讨上皮性卵巢癌患者行腹主动脉旁淋巴结清除术与其生存预后的关系。方法:回顾分析卵巢癌肿瘤细胞减灭术的80例患者,将其中行腹主动脉旁淋巴结(PAN)+盆腔淋巴结(PLN)清除术分为A组(30例),仅行PLN清除术者分为B组(50例),分析PAN清除与患者生存预后的相关性。结果:行卵巢肿瘤细胞减灭术的80例患者中,32例(40.0%)发生淋巴结转移。A组中19例发生淋巴结转移,其中仅PAN阳性7例,仅PLN阳性3例,PAN和PLN均阳性9例;B组中13例发生PLN转移。A与B组患者的淋巴结转移与临床分期、肿瘤细胞分化程度和组织学类型显著相关(P0.05)。A组中淋巴结转移部位以PAN最多16例,其余依次为髂内、闭孔、髂总、腹股沟及髂外淋巴结。A组患者的3年、5年生存率分别为77.9%和46.7%,均高于B组(69.0%和39.2%),但无显著差异(P0.05)。A与B组患者中转移至PLN者的3年生存率分别是68.5%和41.4%,5年生存率是49.7%和26.4%,两组比较差异显著(P=0.044)。A组患者中淋巴结阳性与阴性患者3年生存率分别为43.5%和72.7%,5年生存率是27.2%和58.5%,差异显著(P=0.048)。Cox模型单因素分析提示,淋巴结状态对患者的生存率有影响(P0.01),而且是死亡风险因素。结论:腹主动脉旁淋巴结的清除对改善卵巢癌患者预后起着重要作用。     

Learning curve analysis of laparoscopic radical hysterectomy and lymph node dissection in early cervical cancer

Objective

We aimed to evaluate the learning curve for laparoscopic radical hysterectomy and lymph node dissection (LRHND) in uterine cervical cancer and to compare the surgicopathologic outcomes of cases treated in the first half of the curve with those treated in the second half of the curve.

Study design

The medical records of LRHND patients between August 2004 and April 2011 were reviewed retrospectively. The patients were divided into two groups of the first 35 cases (phase I) and the second 35 cases (phase II). All operations were performed by the same surgeon. Demographic data and surgicopathologic parameters were analyzed. The learning curve was evaluated using the cumulative summation (CUSUM) technique.

Results

No difference was found in demographics and histologic type between the two groups. The mean operating time (307.7 ± 85.8 min) of phase I was significantly longer than phase II (266.3 ± 58.8 min) (P = 0.021). The number of complications in phase I patients (N = 9) was significantly higher than that (N = 1) of phase II patients (P = 0.013). There were no significant differences between the two groups with respect to lymph node yield and likelihood of identifying positive lymph nodes, resection margins, parametrium, stromal invasion, and lymphovascular space invasion. Disease-free survival did not differ between the two groups (P = 0.142). The learning period for LRHND to reach a turning point was calculated to be 40 cases.

Conclusions

An extended learning period can be required for LRHND, during which survival and pathologic outcome of LRHND may not be adversely affected.     

Axillary lymph node dissection in the case of sentinel lymph node micrometastatic invasion: evaluation of three predictive models

Objective

To evaluate three predictive risk models of non-sentinel lymph node (NSLN) involvement in the case of micrometastatic sentinel node (SLN) involvement for breast cancer.

Study design

This retrospective study included 72 successive patients with micrometastatic SLN involvement who had surgery between March 1996 and October 2007. All patients had undergone immediate or delayed axillary lymph node dissection (ALND). The Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram, the Stanford nomogram and the Tenon score were applied to the population to calculate the probability of NSLN involvement.

Results

For the MSKCC nomogram with a threshold value of 10%, sensitivity was 50%, specificity was 70% and the negative predictive value (NPV) was 89%. The area under the receiver operating characteristic curve (AUC) was 0.6 (significant). Use of this nomogram would have avoided ALND in 49 out of 72 (68%) patients, but five out of 10 (50%) patients with NSLN involvement would not have been detected. With a threshold value of 7%, the AUC was 0.69, sensitivity was 90% and NPV was 97%. ALND would have been avoided in 31 out of 72 (43%) patients, with a 3% chance of leaving metastases when abstaining from ALND. For the Tenon score with a threshold value of 3.5, sensitivity was 50%, specificity was 72% and the AUC was 0.62. This was not clinically applicable because eight out of 10 (80%) patients with NSLN involvement would not have been detected. For the Stanford nomogram, the results could not be interpreted because the AUC was not significant.

Conclusion

None of the tested models are sufficiently reliable for use in daily practice. The MSKCC nomogram showed the most encouraging results, especially for a threshold value of 7%, but this has not been validated in the literature. Complete axillary dissection should be performed in the case of micrometastatic SLN involvement until more data become available.     

A postoperative scoring system for distant recurrence in node-positive cervical cancer patients after radical hysterectomy and pelvic lymph node dissection with para-aortic lymph node sampling or dissection

Objective

To identify risk factors for distant recurrence in node-positive cervical cancer patients who underwent radical hysterectomy and pelvic lymph node dissection (PLND) with para-aortic lymph node sampling (PALNS) or para-aortic lymph node dissection (PALND).

Laparoscopic dissection of the ureter for radical laparoscopic hysterectomy

The most important step in radical hysterectomy is freeing the ureter from the anterior parametrium. In this paper we describe our modified technique for freeing the ureter from the anterior parametrium for a Piver II–III radical hysterectomy by means of pure laparoscopic surgery. Our series consists of seventeen patients undergoing laparoscopic hysterectomy. In evaluating the technique, we considered its feasibility, the operating time, the time for complete preparation of the ureter as measured on the videotapes of the procedures, the short-term complication rate, and the length of hospital stay. Thirty-one ureters were unroofed; in three patients, monolateral dissection was performed. The median time of the surgical procedures was 182 min (range 110–255). The median time to unroof the ureter on one side was 14 min 35 s (range 10 min 15 sec–63 min). No patient had ureteronephrosis at ultrasound at control. Even if the experience with this technique is limited, the almost constant time to free the ureter shows that, laparoscopically, it can be performed with relative ease, particularly in patients without prolapse.     

Radical hysterectomy and pelvic lymph node dissection

Twenty-five years' experience with radical hysterectomy and pelvic lymph node dissection in early carcinoma of the cervix is presented. The results indicate that younger patient ovarian salvage was successful. The patients with postoperative positive pelvic nodes were treated by external radiation therapy. Urinary tract complications of atonic bladder have presented a problem that has not been solved. The indications for operation continue to increase and, we feel, will continue to increase in the future because of the early diagnosis of cervical cancer and a greater number of patients that fit this category.     

Learning curve analysis of laparoscopic radical hysterectomy and lymph node dissection in early cervical cancer

Objective

Locally advanced bulky cervical cancer (LABCC) is characterized by poor local control. The objective of this study was to identify the clinicopathologic variables associated with one-year central-only recurrence, which will serve as criteria for adjuvant hysterectomy after radiation (AHR) in patients with LABCC.

Study design

Between January 2000 and August 2007, we retrospectively evaluated outcomes in 225 patients with LABCC who were initially treated with radiation or chemoradiation.

Results

Among the 225 patients with LABCC, there were 41 recurrences within one year after treatment (8 central-only and 33 pelvis and/or distant site recurrences). Age, stage, and treatment type were not associated with the one-year central-only recurrences, but tumor size ≥8 cm had a statistically significant association based on multivariate analysis (OR, 5.39; 95% CI, 1.15–25.31; p = 0.03). The combination of non-squamous cell (non-SCC) type and tumor size ≥8 cm had a significantly higher rate of recurrence within one year (OR, 43.0; 95% CI, 4.78–386.68; p < 0.01).

Conclusions

Of patients with LABCC, those with non-SCC tumors ≥8 cm in size were at high risk for early central-only recurrence after cisplatin-based chemoradiation, and represent the subset of patients for whom AHR is beneficial.     

Predicting pelvic lymph node metastasis in endometrial carcinoma

BACKGROUND: To determine the possibility of individualizing the pelvic lymph node dissection in patients with endometrial cancer, the relationship between pelvic lymph node (PLN) metastasis and various prognostic factors was retrospectively investigated. METHODS: From 1979 to 1994, 175 patients with endometrial carcinoma were treated with either total or radical hysterectomy combined with a PLN dissection as initial therapy. The prognostic factors examined included clinical stage, patient age, histological grade, the microscopic degree of myometrial invasion (DMI), cervical invasion, adnexal metastasis, and macroscopic tumor diameter (TD). RESULTS: Of the 175 patients undergoing PLN dissection, 24 (14%) had PLN metastasis. An endometrial cancer with PLN metastasis had a significantly longer diameter than those without PLN metastasis. The frequency of PLN metastasis increased along with increases in tumor diameter. A logistic regression analysis revealed DMI and TD to be independently correlated with PLN metastasis. The formula based on the coefficients of TD and DMI obtained from the analysis also showed a good correlation, which allowed us to estimate the probability of patients having PLN metastasis. CONCLUSIONS: DMI and TD could accurately estimate the status of PLN in endometrial carcinoma patients.     

Do the pelvic lymph nodes predict the parametrial status in cervical cancer stages IB–IIA?

The aim of this study was to determine whether the pelvic lymph nodes would predict the parametrial status in patients with cervical cancer stages IB1-IIA submitted to radical surgery and pelvic lymphadenectomy. To this end, we evaluated the relationship between positive and negative pelvic lymph nodes and their parametria. Our final purpose was to use this information to recommend the tailoring of the parametrial resection according to the status of pelvic lymph nodes to decrease the morbidity related with radical paratrectomy. From January 1996 to December 2001, 107 consecutive patients with cervical cancer stages IB1 and IIA were primarily treated by radical hysterectomy type III with systematic pelvic lymphadenectomy in a prospective study. Parametria were studied in two sections: the first included the tissue adjacent to the cervix, and the second the distal 2/3. Lymph nodes were routinary processed. Twenty-two patients (20.6%) had positive pelvic nodes and 16 patients (14.9%) had parametrial involvement, mostly by direct extension. Eight patients with positive pelvic nodes (36.4%) had parametrial involvement, whereas among 85 patients with negative pelvic nodes only eight patients (9.4%) had parametrial involvement (P < 0.001), most in internal parametria (62.5%). The sensitivity of pelvic lymph nodes for parametrial involvement was 50% and the positive predictive value was 36.4%, whereas the specificity was 84.6%; and the negative predictive value 90.6%. In the group of negative pelvic lymph nodes, only two patients (2.3%) had parametrial involvement beyond internal parametria. The univariated and multivariated analysis of prognostic factors was always significant but without a significant independent factor for positive parametria. Pelvic lymph nodes appear as good predictors of parametrial status, especially in node-negative patients, and could be used to decrease the paratrectomy in radical surgery.
