Stromal invasion of the cervix can be excluded from the criteria for using adjuvant radiotherapy following radical surgery for patients with cervical cancer

BACKGROUND: Regarding complications of radiotherapy, the indications for adjuvant radiotherapy should be restricted. We conducted the present study to determine whether deep stromal invasion of the cervix could be excluded from the criteria used to identify patients for this treatment surgery. METHODS: This study included 115 patients with FIGO stage Ib to IIb cervical cancer who underwent radical hysterectomy and pelvic lymph node dissection. Patients had the following tumors: 61 nonkeratinizing squamous cell carcinoma, 21 keratinizing squamous cell carcinoma, 26 adenocarcinoma, and 7 adenosquamous cell carcinoma. Our study criteria for using adjuvant radiotherapy included positive lymph node involvement, a compromised surgical margin, or parametrial extension. Deep stromal invasion of the cervix was excluded from the criteria in this study. RESULTS: Seventy-two of the 115 patients (62.6%) underwent radical surgery only and all were alive. The remaining 43 patients received a complete course of external irradiation following radical surgery. The estimated 5-year survival rate is 100% for patients with stage Ib, 93.3% for stage IIa, and 52.7% for stage IIb. Fifty-five patients (47.8%) had deep stromal invasion. The prognosis for patients with deep stromal invasion was significantly worse than that for patients without deep stromal invasion (5-year survival rate, 69.8% vs. 98.0%). However, 21 patients (18.3%) with deep stromal invasion, but without positive lymph node involvement, compromised surgical margin, or parametrial extension, were alive without recurrence. Multivariate analysis showed that lymph node involvement and parametrial extension were independent prognostic factors, but that deep stromal invasion was not. CONCLUSION: Deep stromal invasion of the cervix can be excluded from the list of criteria for selecting patients with cervical cancer who would benefit from adjuvant radiotherapy following radical surgery.     

子宫颈鳞癌Ⅰb～Ⅱa期患者预后预测系统的建立及其临床意义

目的分析子宫颈鳞癌Ⅰb~Ⅱa期患者的预后影响因素并建立预后预测系统,以探讨其在指导术后辅助治疗中的作用。方法回顾性分析接受手术治疗的306例Ⅰb~Ⅱa期宫颈鳞癌患者的临床病理资料,对影响其预后的因素进行单因素和多因素分析。结果306例患者的5年生存率为78 1%。单因素分析结果显示,与其预后有关的因素为淋巴结转移、病理分化程度、肿瘤直径、宫旁组织浸润、深肌层浸润和脉管内瘤栓(P<0 05);多因素分析结果显示,淋巴结转移、深肌层浸润、宫旁组织浸润是影响其预后的独立危险因素(P<0 05)。根据危险因素的不同建立预后预测系统,即将患者分为低危组、中危组和高危组3组,其5年生存率分别为90 3%、83 9%和43 1%。低危组(无危险因素或仅宫旁组织浸润)局部复发的发生率仅为2 2%;中危组(深肌层浸润或合并有宫旁组织浸润)局部复发的发生率为13 5%,远处转移的发生率为1 3%, 局部复发合并远处转移的发生率为0 6%;高危组(淋巴结转移或合并其他危险因素)局部复发和远处转移的发生率分别为25 9%和48 3%,局部复发合并远处转移的发生率为10 3%。结论淋巴结转移、深肌层浸润、宫旁组织浸润是影响Ⅰb~Ⅱa期宫颈鳞癌患者预后的独立因素;根据预后影响因素建立的预后预测系统有助于指导术后辅助治疗。     

Radiotherapy is not indicated in patients with vulvar squamous cell carcinoma and only one occult intracapsular groin node metastasis

ObjectiveMost guidelines advise no adjuvant radiotherapy in vulvar squamous cell carcinoma and a single occult intracapsular lymph node metastasis. However, several recent studies have questioned the validity of this recommendation. The aim of this study was to analyze the groin recurrence rate in patients with a single intracapsular positive lymph node treated without adjuvant radiotherapy.MethodsPatients with a single clinically occult intracapsular lymph node metastasis, treated without adjuvant radiotherapy, formed the basis for this study. Groin recurrences, and the risk of death, were analyzed in relation to the size of the metastasis in the lymph node and the lymph node ratio. Data were analyzed using SPSS, version 26.0 for Windows.ResultsAfter a median follow-up of 64 months, one of 96 patients (1%) was diagnosed with an isolated groin recurrence and another two (2.1%) were diagnosed with a combination of a local and a groin recurrence. The only isolated groin recurrence occurred in a contralateral lymph node negative groin. Size of the metastasis and lymph node ratio had no impact on the groin recurrence risk, nor on survival. The 5-year actuarial disease-specific and overall survivals were 79% and 62.5% respectively. The 5-year actuarial groin recurrence-free survival was 97%.ConclusionBecause of the low risk of groin recurrence and the excellent groin recurrence-free survival, we recommend that adjuvant radiotherapy to the groin in patients with vulvar squamous cell carcinoma and a single occult intracapsular lymph node metastasis can be safely omitted to prevent unnecessary toxicity and morbidity.     

宫颈小细胞癌与非小细胞癌临床特征及预后的对比研究

目的:对比性研究宫颈小细胞癌(SCCC)与宫颈非小细胞癌在发病特点、临床特征、治疗方案、预后情况等方面的差异,并探究影响其预后的因素。方法:回顾性分析2003年5月至2015年6月四川大学华西第二医院收治的宫颈小细胞癌患者63例(SCCC组)和根据诊断时间及相近的FIGO分期配对的宫颈非小细胞癌(鳞癌、腺癌)患者60例(对照组)的临床病理资料及生存情况,采用Pearson卡方检验或Fisher确切概率法比较两组临床特征、治疗方案等方面的差异,Kaplan-Meier方法比较两组总体生存率及无病生存率的差异,单因素和多因素分析影响SCCC预后的因素。结果:(1)SCCC组患者初诊的中位年龄较对照组年轻(40岁vs 44岁,P=0.001),淋巴结转移率、宫旁浸润率、脉管累及率及手术切缘阳性率也均显著高于对照组(P0.05)。而在临床症状、肿块大小、诊断分期、术前治疗、术后治疗等方面比较两者差异均无统计学意义(P0.05)。(2)生存分析中,SCCC组的累积5年生存率(29.2%)与累积5年无瘤生存率(26.6%),显著低于对照组(分别为82.6%、76.7%),差异有统计学意义(P0.05)。(3)在影响SCCC预后的多因素COX多元回归分析结果显示,有淋巴结转移是影响患者5年总生存率和5年无瘤生存率的独立危险因素(HR=4.784、3.067,P0.05)。肿块直径≥4 cm是影响5年总生存率的独立危险因素(HR=3.610,P0.05)和FIGO分期(ⅠB2以上)是影响无瘤生存率的独立危险因素(HR=2.793,P0.05)。结论:SCCC患者更年轻,其临床症状、病灶外观、治疗方案等和宫颈非小细胞癌相似,但淋巴结转移率、脉管累及率、宫旁浸润率及手术切缘阳性率均显著高于宫颈非小细胞癌,预后极差。影响SCCC患者预后的主要因素为有无淋巴结转移、FIGO分期、肿块直径。     

淋巴结转移的Ⅰb 1～Ⅱb期子宫颈癌患者手术后的综合治疗及预后分析

Prognostic factors in FIGO stage IB cervical cancer without lymph node metastasis and the role of adjuvant radiotherapy after radical hysterectomy

OBJECTIVES: The aim of this study was to evaluate the clinical and pathologic prognostic variables for disease free survival, overall survival and the role of adjuvant radiotherapy in FIGO stage IB cervical carcinoma without lymph node metastasis. METHODS: A retrospective review was performed of 393 patients with lymph node negative stage IB cervical cancer treated by type 3 hysterectomy and pelvic lymphadenectomy at the Hacettepe University Hospitals between 1980 and 1997. RESULTS: The disease free survival and overall survival were 87.6 and 91.0%, respectively. In univariate analysis, tumor size, depth of invasion, vaginal involvement, lympho-vascular space involvement (LVSI) and adjuvant radiotherapy were found significant in disease free survival. Overall survival was affected by tumor size, LVSI, vaginal involvement and adjuvant radiotherapy. Tumor size, LVSI and vaginal involvement were found as independent prognostic factors for overall and disease free survival in multivariate analysis. Disease free survival, recurrence rate and site did not differ between patients underwent radical surgery and radical surgery plus radiotherapy. CONCLUSION: Tumor size, LVSI and vaginal involvement were independent prognostic factors in lymph node negative FIGO stage IB cervical cancer. Adjuvant radiotherapy in stage IB cervical cancer patients with negative nodes provides no survival advantage or better local tumoral control.     

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.     

Squamous carcinoma of the vulva: results of treatment, 1938 to 1976.

Clinical data on 264 patients with squamous cell carcinoma of the vulva seen between 1938 and 1976 are reported. Two hundred and four patients were "eligible" for 5 year assessment for a 55% survival rate. Patients treated with radical vulvectomy and bilateral lymphadenectomy had a corrected 5 year survival rate of 86% if the lymph nodes failed to show metastatic disease. Twenty-eight percent of the patients treated with lymphadenectomy had lymph node metastasis at the time of surgery. The presence of lymphatic metastasis appeared to be the most significant prognostic factor. The results obtained have led to a degree of individualization in current treatment policies, together with a re-evaluation of the possible role of radiotherapy.     

A comparison of prognoses of FIGO stage IB adenocarcinoma and squamous cell carcinoma

OBJECTIVES: The objective of this study was to compare clinical and pathologic variables and prognosis of FIGO stage IB adenocarcinoma and squamous cell carcinoma of uterine cervix. METHODS: A retrospective review was performed of 521 patients with stage IB squamous cell carcinoma and adenocarcinoma of cervix who treated primarily by type 3 hysterectomy and pelvic and/or para-aortic lymphadenectomy at Hacettepe University Hospitals between 1980 and 1997. RESULTS: Age, tumor size, grade, depth of invasion, lymph node metastasis, parametrial, vaginal, and lymphvascular space involvement (LVSI) were not different between two cell types except number of the lymph nodes involved. Metastasis to three or more lymph nodes was significantly higher in adenocarcinoma. Overall and disease-free survival were 87.7%, 84.0% versus 86.4%, 83.1% for squamous cell carcinoma and adenocarcinoma, respectively (P > 0.05). The rate and site of recurrence were not different between two cell types. Multivariate analysis of disease-free and overall survival revealed independent prognostic factors as tumor size, LVSI, number of involved lymph node, and vaginal involvement. CONCLUSION: Prognosis of FIGO stage IB cervical cancer patients who were treated by primarily radical surgery was found to be same for those with adenocarcinoma and squamous cell carcinoma.     

局部晚期宫颈癌100例淋巴结转移特点及临床分析

目的：探索局部晚期（ⅠB2/ⅡA2期）宫颈癌的淋巴结转移特点及新辅助化疗对预后及并发症发生率的影响。方法：回顾性分析2008年1月-2016年12月南京医科大学第一附属医院收治的424例ⅠA2～ⅡA2期宫颈鳞癌或腺癌患者的临床资料,随访每位患者的生存情况,比较局部晚期宫颈癌患者淋巴结转移情况及新辅助化疗和直接手术患者在手术并发症及预后方面的差异。结果：共424例宫颈癌患者纳入研究,100例局部晚期宫颈癌患者中有68例直接行根治性手术治疗,32例先行1～2次介入或静脉新辅助化疗后行宫颈癌根治术,术后病理提示盆腔淋巴结转移者20例,没有发现腹主动脉旁淋巴结转移。单因素分析提示深肌层浸润、淋巴脉管间隙浸润（lymph vascular space invasion,LVSI）与淋巴结转移相关（P＜0.05）;组织学类型、分化程度、是否行新辅助化疗与淋巴结转移无关（P＞0.05）。将有统计学意义的单因素进行Logistic回归分析显示,LVSI为淋巴结转移的独立危险因素（P＜0.05）。新辅助化疗组淋巴结转移率为22.2％,手术组则为17.2％,2组比较差异无统计学意义（P＞0.05）。总生存期及无瘤生存期方面,局部晚期宫颈癌明显低于早期者。新辅助化疗组的术后感染发生率较低,手术时间和腹腔引流管留置时间较短,但2组差异无统计学意义（P＞0.05）,而术中输尿管支架置入率、输血率、其他相邻脏器损伤的发生率2组相似。结论：局部晚期宫颈癌预后较早期差,淋巴结转移率明显高于早期,盆腔淋巴结转移主要与LVSI及深肌层浸润有关。新辅助化疗对局部晚期宫颈癌的影响尚不明确,也没有证据证明新辅助化疗影响盆腔淋巴结转移的检出率,在手术相关并发症的发生率方面还需更大样本或多中心的研究。

The prognostic factors for patients with early cervical cancer treated by radical hysterectomy and postoperative radiotherapy

PURPOSE: This study was undertaken to evaluate the efficacy of postoperative radiotherapy (post-OP RT) and to investigate the prognostic factors for early-stage cervical cancer patients who were treated by radical surgery, and the pathological findings suggested a relatively high risk of relapse with surgery alone. MATERIALS AND METHODS: From January 1990 to December 1995, 222 patients with stage IB-IIA cervical cancer, treated by radical surgery and a full course of post-OP RT, were included in this study. The indications for post-OP RT were based on pathological findings, including lymph node metastasis, positive surgical margins, parametrial extension, lymphovascular permeation, and invasion of more than two-thirds of the cervical wall thickness. The radiation dose of external beam was 44-45 Gy to the whole pelvis and 50-54 Gy to the true pelvis. One hundred seventy-two patients also received intravaginal brachytherapy as a local boost. The minimal follow-up period was 2 years. RESULTS: The actuarial 5-year overall and disease-specific survival rates for all patients were 76 and 82%, respectively. The tumor control rate within the pelvis reached 94%, and distant metastasis was the major cause of treatment failure. Univariate analysis of clinical and pathological parameters revealed that clinical stage, bulky tumor size, positive lymph nodes, parametrial extension, and histologic type were significant prognostic factors. After multivariate analysis, only positive lymph nodes (P = 0.01), bulky tumor size (P = 0.02), and parametrial extension (P = 0.05) independently influenced the disease-specific survival (DSS). For patients with lymph node metastasis, the number and location of the nodal involvement significantly affected the prognosis. The 5-year DSS for patients with no, one, and more than one lymph node metastasis were 87, 84, and 61% (P = 0.0001), respectively. Patients with upper pelvic lymph node metastasis had a higher incidence of distant metastasis (50% vs 16% in lower pelvic node group, P = 0.03). In the subgroup of single lower pelvic nodal metastasis, the prognosis was similar to that of patients without lymph node involvement (5-year DSS 85% vs 87%, P = 0.71). CONCLUSION: Our results indicate that post-OP RT can achieve very good local control in stage IB-IIA cervical cancer patients whose pathological findings show risk features for relapse after radical surgery. The prognostic factors for treatment failure identified in this study can be used as selection criteria for clinical trials to test the effects of other adjuvant treatments, such as chemotherapy. Patients with a single lower pelvic lymph node metastasis have a relatively good prognosis and may not need adjuvant treatment beyond radiation therapy.     

Lymph node positivity in cervical cancer

From January 1962 until July 1978, 44 patients with invasive cervical cancer at exploratory surgery were found to have positive lymph nodes. Forty-three of these patients received radiation as definitive therapy after the discovery of lymph node metastasis. One patient had a positive left scalene biopsy as well and was treated only with chemotherapy. Thirty-three of the patients were clinically Stage IB. Two patients were Stage IIA, while 7 were IIB. There was 1 individual staged as IIIB. One patient was unstageable because of carcinoma found at operation for benign disease. Histologically, 35 of the 44 had squamous cell carcinoma. Five patients had adenocarcinoma, while 2 were adenosquamous. One patient was noted to be glassy cell type, and 1 patient had small cell undifferentiated carcinoma. Evaluation of the 44 operative specimens comparing clinical stage to highest positive node revealed that 32 patients (73%) had external iliac/obturator node involvement. Twenty-five of these were clinically Stage I disease. Twelve patients (27%) had involvement above the external iliac/obturator level and 8 of these were clinically Stage I. It is evident that a number of patients who are thought to have early disease clinically may have more advanced disease surgically and pathologically. Using the actuarial method of Berkson and Gage, the 5-year survival rate of the entire 44 operated patients was 52%. For comparison with other studies, we have additionally divided the patients into: (1) 22 who had completed hysterectomies and lymph node dissections followed by radiotherapy; (2) 22 who had lymph node sampling followed by radiation or chemotherapy alone. The actuarial survival of the first group was 71%. The survival of the second group, which included clinical Stages I, II, and III and one unstageable patient, was 34%.     

Effectiveness of definitive radiotherapy for squamous cell carcinoma of the vulva with gross inguinal lymphadenopathy

Objective

To evaluate the effectiveness and long-term side effects of definitive groin radiotherapy for vulvar cancer with grossly involved inguinal lymph nodes.

Prognostic significance of single versus multiple lymph node metastases in cervical carcinoma stage IB

From January 1, 1970, to December 31, 1985, 51 patients with stage IB (FIGO) carcinoma of the cervix with lymph node metastases were treated at the University Hospital, Groningen, The Netherlands. The survival rate was 54% and the average duration of follow-up was 78 months (range 47-132). Important clinical variables for survival were investigated retrospectively: the survival rate in patients with a single lymph node metastasis (with tumor confined to the node itself) (n = 23) appeared to be much better than that of patients with multiple node involvement and/or single nodes with extranodular tumor infiltration (n = 28); survival was 85 and 24%, respectively (P less than 0.001). The same applied to patients with only occult lymph node involvement: the survival rate in patients with occult involvement of the hypogastric, external iliac, or obturator nodes was 87% in 19 patients with a single metastasis and 53% in 15 patients with multiple node involvement (P less than 0.02). The survival rate in 8 patients with adenomatous histological components was 42%. In 42 patients with squamous cell carcinoma, the survival rate was 56%. This difference was not statistically significant. Treatment complications and the effect of treatment on the site of recurrence were investigated.     

Isolated full-thickness cervical stromal invasion warrants post-hysterectomy pelvic radiotherapy in FIGO stages IB-IIA uterine cervical carcinoma

OBJECTIVE: To evaluate the potential benefit of postoperative radiotherapy (PORT) in women with isolated full-thickness cervical stromal invasion (FTSI) as an unfavorable pathological finding after radical hysterectomy and pelvic lymph node dissection (PLND) in FIGO stages IB-IIA cervical carcinoma. METHODS: A total of 1868 patients with stages IB-IIA cervical carcinoma underwent radical hysterectomy and PLND between January 1982 and December 2002. Seventy-four of these patients had isolated FTSI without any other unfavorable pathological finding, such as lymph node metastasis, microscopic parametrial involvement, involved resection margin, lympho-vascular space invasion, or large clinical tumor diameter (>4 cm). Forty-one of these patients had no adjuvant treatment (S group) and 33 received PORT (PORT group). Patients with isolated FTSI who received chemotherapy were excluded. Treatment outcomes in the PORT and S groups were compared. RESULTS: Ten-year disease-free survival (DFS) and pelvic-failure-free survival (PFFS) of S group vs. PORT group were 73.2% vs. 92.4% (P=0.038) and 79.8% vs. 97.0% (P=0.044), respectively. According to a Cox proportional hazards model developed by forward, stepwise regression incorporating all prognostic variables, only PORT was marginally significant for DFS (RR 0.234; 95% CI 0.051-1.067; P=0.061) and significant for PFFS (RR 0.055; 95% CI 0.005-0.620; P=0.019). A grade 4 late complication developed in two patients (6%) in PORT group. CONCLUSION: PORT administered to patients with isolated FTSI after radical hysterectomy and PLND improves pelvic control in FIGO stages IB-IIA cervical carcinoma with acceptable morbidity.     

Multivariate analysis of histopathologic prognostic factors for invasive cervical cancer treated with radical hysterectomy and systematic retroperitoneal lymphadenectomy

BACKGROUND: The aim of this study was to identify the independent histopathologic prognostic factors for patients with cervical carcinoma treated with radical hysterectomy including paraaortic lymphadenectomy. METHODS: A total of 187 patients with stage IB to IIB cervical carcinomas treated with radical hysterectomy and systematic retroperitoneal lymphadenectomy were retrospectively analyzed. The median follow-up period was 83 months. Cox regression analysis was used to select independent prognostic factors. RESULTS: Using multivariate Cox regression analysis, lymph node (LN) status (negative vs. metastasis to pelvic nodes except for common iliac nodes vs. common iliac/paraaortic node metastasis), histopathologic parametrial invasion, lymph-vascular space invasion (LVSI), and histology of pure adenocarcinoma were found to be independently related to patients' poor survival. For patients who had a tumor histologically confined to the uterus and have neither parametrial invasion nor lymph node metastasis, LVSI was the most important prognostic factor, and histologic type, depth of cervical stromal invasion, and tumor size were not related to survival. The survival of patients with a tumor extending to parametrium or pelvic lymph node(s) was adversely affected by histology of pure adenocarcinoma. When the tumor extended to common iliac or paraaortic nodes, patients' survival became quite poor irrespective of LVSI or histologic type of pure adenocarcinoma. Patients' prognosis could be stratified into low risk (patients with a tumor confined to the uterus not associated with LVSI: n = 80), intermediate risk (patients with a tumor confined to the uterus associated with positive LVSI, and patients with squamous/adenosquamous carcinoma associated with pelvic lymph node metastasis or parametrial invasion: n = 86), and high risk (patients with pure adenocarcinoma associated with pelvic lymph node metastasis or parametrial invasion, and patients with common iliac/paraaortic node metastasis: n = 21) with an estimated 5-year survival rate of 100 +/- 0 (mean +/- SE)%, 85.5 +/- 3.9%, and 25.1 +/- 9.7%, respectively. CONCLUSIONS: LN status, parametrial invasion, LVSI, and histology of pure adenocarcinoma are important histopathologic prognostic factors of cervical carcinoma treated with radical hysterectomy and systematic retroperitoneal lymphadenectomy. Prognosis for patients with cervical carcinoma may be stratified by combined analysis of these histopathologic prognostic factors. Postoperative therapy needs to be individualized according to these prognostic factors and validated for its efficacy using randomized clinical trials.     

A clinicopathological study on adenocarcinoma of the uterine cervix

A total of 102 cases of adenocarcinoma of the uterine cervix were reviewed to define the clinical and pathological behavior. In the 18 years between 1970 and 1987 the incidence of cervical adenocarcinoma increased. The rate of lymph node involvement in stage Ib was 16.1% (5/31) and in stage II 26.2% (11/42). There was no difference between the rate of lymph node involvement in adenocarcinoma and squamous cell carcinoma. The 5-year survival rates were as follows: stage I 83.3% (25/30), stage II 58.1% (18/31), stage III (0/4), stage IV (2/5), and all stages 64.3% (45/70). The 5-year survival rate for patients with adenocarcinoma was poor in contrast to that for patients with squamous cell carcinoma (p less than 0.05). It was suggested that adenocarcinoma was less radiosensitive than squamous cell carcinoma.     

子宫颈癌伴盆腔淋巴结转移患者的复发及预后分析

目的 探讨宫颈癌伴盆腔淋巴结转移患者的复发规律及预后影响因素.方法 选取1994年1月至2001年12月问中山大学肿瘤防治中心收治的按国际妇产科联盟(FIGO)的标准其临床分期为I b1～II a期的宫颈癌伴盆腔淋巴结转移的患者共124例,结合临床病理资料对其复发及预后情况进行回顾性分析.结果 患者的5年总生存率和5年无瘤生存率分别为63.3%、61.4%;总复发率为39.5%(49/124),其中复发部位明确的41例患者(盆腔内、盆腔外和盆腔内外同时复发患者分别为25、13和3例)中盆腔内复发率(61.O%,25/41)显著高于盆腔外复发率(31.7%,13/41;P=0.008).多因素分析显示,髂总淋巴结转移是影响患者预后的独立的危险因素(P=0.035).根据这一因素,将盆腔淋巴结转移的患者分为低危组(髂总淋巴结无转移,104例)和高危组(髂总淋巴结转移,20例),其5年无瘤生存率分别为69.4%和24.5%,两组比较,差异有统计学意义(P=0.003);低危组盆腔内复发率为22.1%(23/104),高危组为25.0%(5/20),两组比较,差异无统计学意义(P>0.05);低危组盆腔外复发率为7.7%(8/104),高危组为40.O%(8/20),两组比较,差异有统计学意义(P<0.01).结论 伴盆腔淋巴结转移的宫颈癌患者以盆腔内复发为主,而其中髂总淋巴结转移者以盆腔外复发为主.髂总淋巴结转移是影响宫颈癌患者预后的独立的危险因素.     

Comparison of clinical versus surgical staging systems in vulvar cancer.

OBJECTIVE: To compare prognostic information from the new surgical staging system of the International Federation of Gynecology and Obstetrics (FIGO) with the old clinical staging system for vulvar cancer. METHODS: One hundred six women with previously untreated squamous cell carcinoma of the vulva who underwent radical vulvectomies and inguinal lymph node dissections at the University of Oklahoma from 1971-1990 were considered eligible for this study. A retrospective chart review was conducted to assign surgical stage. The clinical and pathologic factors analyzed for survival included the clinical and surgical stage of disease, nodal status, tumor size, and lesion location. RESULTS: Overall 5-year survival was 64%. Forty-three patients had inguinal and femoral node metastasis with a 5-year survival of 38%, versus 87% for patients without nodal metastasis (P < .00001). An increased number of positive groin lymph nodes was associated with a poorer prognosis. Thirty-one patients had tumors of 2 cm or less in maximum diameter with no recurrences, versus 52% 5-year survival in the remaining patients (P < .001). Perineal involvement was identified in 24 patients, but did not significantly influence survival. CONCLUSION: Overall, the new classification system revised by FIGO for vulvar cancer staging places patients into more accurate risk categories.
