新辅助化疗在宫颈癌治疗中的应用及疗效观察

目的探讨术前新辅助化疗对局部晚期宫颈癌的治疗效果。方法对55例Ib2～Ⅱb期的宫颈癌患者行新辅助化疗，并对治疗效果进行评价。以同期未行新辅助化疗的33例宫颈癌患者作为对照，比较两组患者术中出血量、宫旁浸润率、阴道切缘阳性率及淋巴结转移率的差异。对患者进行随访，分析新辅助化疗对远期预后的影响。结果新辅助化疗组总有效率为94．6％，病理完全缓解者5例（9．1％）。有效的52例患者接受了手术。新辅助化疗组淋巴结转移率为36．5％，对照组为48．5％，两组比较，无差异（P〉0．05）。但新辅助化疗组中Ⅱ期患者淋巴结转移率（35．3％）低于对照组（69．2％），两者比较，差异有显著性（P〈0．05）。两组的宫旁浸润率分别为1．9％和18．2％，经精确概率法计算，两者比较，差异有显著性（P〈0．05）。术中出血量分别为（874．0±675．6）ml和（493．9±316．7）ml，两者比较，差异有显著性（P〈0．05）。NACT组与对照组的1年无瘤生存率分别为77．78％和81．04％，5年无瘤生存率分别为75．41％和81．04％，1年总生存率分别为93．91％和96．88％，5年总生存率分别为84．37％和88．03％，两组比较，差异均无显著性（P〉0．05）。结论新辅助化疗对局部晚期宫颈癌患者近期疗效显著，但对无瘤生存时间和总生存时间无明显影响。术后化疗、淋巴结转移是影响患者无瘤生存时间的主要因素。     

Ⅱb期宫颈癌的治疗

144例Ⅱb期宫颈癌患者分为6组,a组23例因盆腔淋巴结未检出癌灶仪行根治手术。b组21例因盆腔淋巴结有癌灶,术后加体外放疗。c组36例、d组14例系化疗加根治术治疗,化疗多是经动脉灌注5-Fu及噻替派,无盆腔淋巴结转移者仅化疗—疗程,阳性者化疗二疗程。e组36例、f组14例为对照组接受标准放疗。6组5年生存率分别为86.9%、76.2%、80.5%、50.0%、61.1%和42.9%。

目的 探讨新辅助化疗在宫颈癌治疗中的应用价值。方法 自1991年1月起山东省肿瘤医院开始进行放疗前新辅助化疗的临床前瞻性研究,选择1991年1月～2003年12月符合入组标准的宫颈癌患者共1609例,放疗前给予2个疗程联合化疗（A组）;另选择1989年1月-1990年12月接受单纯放疗的375例宫颈癌患者作对照（B组）。比较两组患者的近期控制情况、长期生存率及并发症的发生情况。结果 A组化疗2个疗程后总有效率为74．5％（1199／1609）,局部完全缓解率为1．6％（25／1609）。A组的3、5、10年生存率分别为90．3％（1017／1126）、75．3％（652／866）、59．0％（200／339）,其中临床分期Ⅱ期患者的5年生存率显著高于Ⅲ期者（P〈0．05）;而两者的3、10年生存率相近（P〉0．05）。B组的3、5、10年生存率分别为81．1％（304／375）、59．2％（222／375）、40．3％（151／375）,其中Ⅱ期患者的5、10年生存率均显著高于Ⅲ期者（P〈0．05）。A、B两组间5、10年生存率比较,差异均有统计学意义（P〈0．05）。A组宫颈腺癌患者的3、5、10年生存率均显著高于B组（P〈0．05）,且A组Ⅲ期患者的3、5年复发率及转移率明显低于B组（P〈0．05）;A组化疗屙的毒副反应主要为轻、中度消化道反应和骨髓抑制,经处理后均能恢复,其近期、远期放疗并发症发生率和B组比较,差异无统计学意义（P〉0．05）。结论 新辅助化疗对宫颈癌的治疗是安全有效的,能明显提高患者的近期疗效和长期生存率,特别是对于宫颈腺癌及临床晚期患者效果尤为显著。     

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。

Treatment of cervical cancer with adjuvant chemotherapy versus adjuvant radiotherapy after radical hysterectomy and systematic lymphadenectomy

Aim:  To compare the clinical efficacy focused on post-treatment morbidity between adjuvant chemotherapy (CT) and pelvic radiotherapy (RT) after radical hysterectomy for patients with cervical cancer.
Methods:  A total of 125 patients with cervical squamous cell carcinoma who underwent radical hysterectomy and pelvic lymphadenectomy at Hokkaido University Hospital between 1991 and 2002 were enrolled in the study for retrospective analysis. Seventy patients with recurrent risk factors, including deep stromal invasion, lymph vascular space invasion, parametrial invasion, lymph node metastasis (LNM), and bulky tumor (≥4 cm), received adjuvant therapy; 42 were treated with RT, and 28 were treated with CT. Almost all patients with multiple LNM received RT. Analyses were also performed on a subgroup of 50 patients without multiple LNM (23 RT, 27 CT). Clinical efficacy of post-treatment morbidity and survival was evaluated.
Results:  Because there were more patients with multiple LNM in the RT group, we analyzed disease-free survival in 50 patients without multiple LNM. The 3-year disease-free survival rate was 82.6% with RT and 96.3% with CT ( P  = 0.16). Postoperative bowel obstruction was significantly more frequent in the RT group versus the CT ( P  = 0.007) and no-therapy ( P  = 0.0026) groups. Urinary disturbance was also more frequent in the RT group than in the CT ( P  = 0.0016) and no-therapy ( P  = 0.089) groups.
Conclusion:  CT has the equivalent therapeutic effect as RT with fewer postoperative complications for patients with intermediate risks. A prospective randomized trial is needed to compare CT combined with radical hysterectomy and pelvic lymphadenectomy to RT or chemoradiotherapy.     

Postoperative adjuvant concurrent chemoradiotherapy improves survival rates for high-risk, early stage cervical cancer patients

OBJECTIVE: This study was undertaken to evaluate the efficacy of postoperative concurrent chemoradiotherapy (CCRT) and to investigate the recurrence and survival rates after adjuvant CCRT in high-risk early cervical cancer (stages IA2, IB, IIA) patients who were treated by radical hysterectomy and pelvic lymphadenectomy. METHODS: From July 1994 to June 2001, we retrospectively reviewed the medical records of 151 patients who had undergone radical abdominal hysterectomy with pelvic lymphadenectomy and paraaortic lymph nodes dissection at Ajou University Hospital for early cervical cancer (stages IA2, IB, IIA). CCRT was performed in 30 patients with high-risk factors such as positive pelvic lymph nodes, parametrial involvement, or positive surgical margins. Adjuvant chemotherapy consisted of cisplatin (70 mg/m(2) on day 1) and 5-fluorouracil (5-FU; 1000 mg/m(2) on days 2-5) for four cycles every 4 weeks beginning 2-3 weeks after surgery. Pelvic radiotherapy was started concurrently at the second and third cycle of chemotherapy. We also analyzed the recurrence pattern and survival rates of 114 patients (control group) who received no adjuvant therapy after surgery. The mean follow-up period was 49 months (24-98 months). RESULTS: There were recurrences in three patients after CCRT (10%) and in five patients in the control group (4.4%). The actuarial 5-year overall survival rates for patients in CCRT and control group were 96.7% vs. 97.7%, respectively. The progression-free survival rates were 88.7% for the high-risk group and 95.4% for the non-high-risk group. CONCLUSIONS: This study confirms good local control and 5-year overall and progression-free survival rates in high-risk cervical cancer patients after CCRT, which is comparable with the results of the control group. Our results indicate that adjuvant concurrent chemoradiotherapy seems to be effective in stages IA2-IIA cervical cancer patients with high-risk factors.     

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.     

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.     

Prognostic factors in pathologic parametrium-positive patients with stage IB-IIB cervical cancer treated by radical surgery and adjuvant therapy

OBJECTIVE: The purpose of the present study was to identify prognostic factors and recurrent patterns in pathologic parametrium-positive patients with stage IB-IIB cervical cancers treated by radical surgery and adjuvant therapy. METHODS: The patient population consisted of 84 individuals presenting with stage IB-IIB cervical cancers and histologically proven parametrial invasion. All these patients were treated postoperatively with adjuvant external whole pelvic irradiation, combination chemotherapy, or chemoradiotherapy. RESULTS: The 5-year disease-free survival rate was found to be 67.2% and 5-year overall survival rate, 75.4%. Multivariate analysis revealed that vaginal invasion (p=0.0008), lymph node metastasis (p=0.002), and non-squamous histology (p=0.010) were independent indicators of the disease-free survival rates and that the vaginal invasion (p=0.009) and lymph node metastasis (p=0.011) were independent prognostic factors for the overall survival rates. The 5-year overall survival rate was approximately 90% for patients without these risk factors. Disease recurrence was observed in 26 patients (31.0%) with a median time of 16.5 months (range, 5-59 months) from the surgery. Hematogenous recurrences, including those in the lung, liver, and bone, were significantly higher in patients with non-squamous cell carcinomas (p=0.008). Distant lymph node recurrences were significantly higher in patients with positive pelvic lymph node and vaginal invasion (p=0.004 and p=0.023, respectively). Pelvic recurrences were significantly higher in patients with vaginal invasion (p=0.026). CONCLUSIONS: Vaginal invasion and lymph node metastasis are independent indicators for disease-free and overall survival rates in pathologic parametrium-positive patients with stage IB-IIB cervical cancer treated by radical surgery and adjuvant therapy. The survival rate is excellent in the patients without these risk factors. Hematogenous recurrence may be evident in patients with non-squamous cell carcinomas.     

Combined modality therapy for stage ⅠB cervical cancer

Objective:To evaluate the current approaches for multimodality therapy for stage ⅠB cervical cancer.Methods:The relevant literature has served as a source for identified high or intermediate risks and management of stage ⅠB cervical cancer.Result:The high risks include pelvic lymph node metastasis(PLNM),positive resection margin(PRM),and the involvement of parametrium(IPM).The intermediate risks include deep stromal invasion(DSI),bulky tumor size(BTS),lymphovascular space invasion(LVSI).Adeno-carcinomatous histotype is the new risk feature relevant to poor prognoses.Both radical hysterectomy plus bilateral pelvic lymph node dissection(PLND) and radical radiotherapy have proven to be equally effective.Surgery is more performed for stage ⅠB1 disease;radiotherapy or chemoradiotherapy is preferable for stage ⅠB2 disease.For patients with one high risk or two of intermediate risks,radical hysterectomy plus PLND followed by concurrent chemoradiotherapy can improve overall survival(OS) and disease-free survival(DFS).Conclusion:The management should be individualized for stage ⅠB cervical cancer.The optimized multidisciplinary therapy can benefit patients with the best cure and minimum morbidity and complications.     

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.

OBJECTIVE: This study was performed to identfy surgical and histopathologic prognostic factors that could predict 5-year disease-free survival (DFS) after patients underwent radical hysterectomy and pelvic-paraaortic lymphadenectomy for FIGO Stage I-II cervical carcinoma. METHODS: A retrospective review was performed for all patients undergoing primary radical hysterectomy and pelvic-paraaortic lymphadenectomy for Stage I-II cervical cancer at Ankara Oncology Hospital from 1995 to 2000. Clinical and pathologic variables including age, tumor size (TS), clinical stage, depth of invasion (DI), lymphovascular space involvement (LVSI), cell type, tumor grade, lymph node metastases (LNM), parametrial involvement, surgical margin involvement and pattern of adjuvant therapy were analyzed using univariate analyses. DFS was performed by the Kaplan-Meier method and the log-rank test. Independent prognostic and predictive factors affecting DFS were assessed by the Cox proportional hazard method. RESULTS: Ninety-three patients underwent primary type III radical hysterectomy and pelvic-paraaortic lymphadenectomy. Five-year DFS was 87.1%. LVSI, parametrial involvement and grade were the prognostic factors that independently affected survival. DFS was not significantly different for age, disease status of the surgical margins, tumor size, depth of invasion, cell type, pelvic lymph node metastases and adjuvant radiotherapy. CONCLUSIONS: LVSI, parametrial invasion and histologic grade 2-3 were independent prognostic factors in early-stage cervical cancer patients. Adjuvant radiotherapy in these patients provides no survival advantage.     

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。
