Adjuvant chemotherapy versus concurrent chemoradiotherapy for high-risk cervical cancer after radical hysterectomy and systematic lymphadenectomy

Background

The aims of this study were to evaluate the efficacy and toxicity of chemotherapy (CT) compared with concurrent chemoradiotherapy (CCRT) after radical hysterectomy and lymphadenectomy in high-risk patients with early-stage cervical cancer and to evaluate whether the radicality of the lymphadenectomy would affect the outcome and toxicity of postoperative adjuvant therapy.

Methods

The cases of all patients (n = 393) with FIGO IB1–IIB cervical cancer who were treated by radical surgery at Shizuoka Cancer Center between January 2002 and December 2013 were reviewed. Of these, 111 patients met the inclusion criteria for this retrospective study: (1) high risk for occurrence due to pathologically confirmed parametrial invasion and/or pelvic lymph node metastasis; (2) postoperative treatment with adjuvant CT or CCRT. The clinical data of these patients were reviewed.

Results

Of the 111 patients, 37 and 74 patients underwent CT and CCRT, respectively. The 4-year progression-free survival rate [PFS; 71.7 (CT) vs. 68.3 % (CCRT)] and overall survival rate [76.0 (CT) vs. 82.7 % (CCRT)] did not differ significantly between the two groups. The CT group contained significantly more patients with severe neutropenia than the CCRT group (66.7 vs. 23.0 %, respectively; p < 0.001), and the CCRT group contained significantly more patients with diarrhea than the CT group (10.8 vs. 0 %, respectively; p = 0.04). The patients who had ≥40 lymph nodes dissected (≥40 group) had higher PFS than the patients who had <40 lymph nodes dissected (<40 group) (73.2 vs. 64.2 %, respectively), although the difference was not significant. In the CT group, there was no significant association between the number of dissected lymph nodes and severe toxicities. However, in the CCRT group, significantly more vomiting (p = 0.046) and edema (p = 0.046) occurred in the ≥40 group than in the <40 group.

Conclusions

Chemotherapy after surgery for high-risk patients had similar efficacy and a different toxicity profile compared with CCRT, and a more radical surgical procedure would improve the survival outcome. However, CCRT was associated with worse toxicity than CT. We advocate a prospective randomized study to compare CT with CCRT for patients with high-risk factors for recurrence.

     

三种方案治疗Ⅰb2、Ⅱa2期宫颈癌患者生存状况及术后并发症的比较

目的 探讨单纯根治手术、新辅助化疗联合根治手术及同步放化疗联合根治手术方案对Ⅰb2、Ⅱa2期宫颈癌患者生存状况及术后并发症的影响。方法 回顾性分析140例Ⅰb2、Ⅱa2期宫颈癌患者临床资料，单纯根治手术治疗48例（A组），新辅助化疗联合根治手术治疗59例（B组），同步放化疗联合根治手术治疗33例（C组）。比较三组患者术中、术后临床指标、局部侵犯和淋巴结转移率、术后并发症发生率、中位总生存时间和术后1、2及3年生存率。结果 三组患者手术用时和总住院时间比较差异无统计学意义（P>0.05）；C组患者手术出血量、术后脉管和深肌层侵犯率及淋巴结转移率均显著低于A、B组（P<0.05）；三组患者术后神经侵犯率、术后并发症发生率、中位总生存时间和术后随访1、2及3年生存率比较差异均无统计学意义（P>0.05）。B组按术前治疗方式又分为放疗组（28例）、化疗组（13例）和放化疗组（18例），放疗组3年生存率明显高于化疗组与放化疗组（P<0.05）。结论 三组方案治疗Ⅰb2、Ⅱa2期宫颈癌生存状况和术后并发症风险相近；但同步放化疗联合根治手术有助于减轻手术创伤，降低术后局部侵犯和淋巴结转移率。     

Neoadjuvant chemotherapy and radical surgery compared to radical surgery alone in bulky stage IB–IIA cervical cancer

AIM: The aim of this study was evaluation of the efficacy of neoadjuvant chemotherapy (NACT) and radical hysterectomy on long-term survival in stage IB-IIA locally advanced cervical cancer as compared with radical surgery alone. METHODS: We reviewed all patients with cervical cancer stage IB-IIA who were treated with two treatment modalities, i.e. NACT followed by radical hysterectomy and lymphadenectomy, and radical hysterectomy alone between March 1996 and March 2004. There were 22 patients in the NACT group (group 1) and 160 patients in the immediate radical surgery group (group 2). All patients in group 1 were followed for more than 108months, and long-term survival and factors affecting recurrence were evaluated. RESULTS: Nineteen patients in the NACT arm underwent radical surgery. Pelvic lymph node metastasis was found in 8 patients in this group and in 36 in the radical surgery group. Eighteen patients in the NACT group and 96 patients in the radical surgery group were scheduled for adjuvant postoperative chemoradiation. During the 9-year follow-up, recurrence rate was 47.1% and 30.2% in NACT and control groups, respectively. In the NACT group lymph node metastasis was a significant independent risk factor for recurrence. Overall survival in the NACT arm was not statistically significantly lower than the control arm (p=0.06). CONCLUSION: NACT did not improve long-term overall survival of bulky early-stage cervical cancer patients compared to primary radical surgery.     

The addition of induction chemotherapy to preoperative, concurrent chemoradiotherapy improves tumor response in patients with esophageal adenocarcinoma

BACKGROUND: Tumor viability assessed by pathologic analysis of resected specimens in patients with preoperatively treated esophageal adenocarcinoma (EAC) is a prognostic indicator. The feasibility of induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) and surgery for patients with locoregionally advanced EAC has been demonstrated. In this study, the authors evaluated the efficacy of CCRT compared with traditional concurrent chemoradiotherapy (CRT). METHODS: The authors retrospectively reviewed 247 consecutive patients with EAC who presented for planned surgery after treatment with either CCRT or CRT from January 1997 through August 2003. Patient demographics, comorbidities, and tumor characteristics were analyzed. Pathologic tumor response, overall survival, and disease-free survival were assessed according to treatment. RESULTS: One hundred seventeen patients received CCRT, and 130 patients received CRT before planned surgical resection. CCRT resulted in a 64% tumor response rate compared with a 51% tumor response rate in the CRT group (odds ratio, 1.73; P = .035). In the CCRT group, the median overall survival was 55 months, and the 3-year overall survival rate was 59%; in the CRT group, the median overall survival was 25 months, and the 3-year overall survival rate was 41% (hazard ratio [HR], 0.69; P = .041). In the CCRT group, the median disease-free survival was 43 months, and the 3-year disease-free survival rate was 54%; in the CRT group, the median disease-free survival was 18 months, and the 3-year disease-free survival rate was 36% (HR, 0.72; P = .047). Subset analysis of patients with clinical Stage III/IVA disease showed a median overall survival of 51 months with a 3-year overall survival rate of 58% in the CCRT group and a median overall survival of 20 months with a 3-year overall survival rate of 28% in the CRT group (HR, 0.57; P = .019). CONCLUSIONS: In patients with EAC, CCRT improved tumor response significantly compared with traditional CRT alone. Overall survival and disease-free survival were increased in patients who received CCRT, especially in the subset of patients who had more advanced disease.     

Concurrent weekly cisplatin plus external beam radiotherapy and high-dose rate brachytherapy for advanced cervical cancer: a control cohort comparison with radiation alone on treatment outcome and complications

PURPOSE: To test, though a control-cohort study, the hypothesis that concurrent chemoradiotherapy (CCRT) using weekly cisplatin, plus high-dose rate intracavitary brachytherapy (HDRICB) is superior to radiation (RT) alone in patients with advanced cervical cancer. METHODS AND MATERIALS: A total of 171 patients with Stage IIB-III cervical cancer were enrolled in this study. Seventy patients were treated with CCRT and the results were compared with those of 101 patients who had been treated with RT using the same protocol at an early period. RT consisted of 45 Gy in 25 fractions to the whole pelvis, followed by a 12.6-Gy boost to the parametrium. Four courses of HDRICB using 6.0 Gy to Point A were performed. Chemotherapy consisted of weekly cisplatin at a dose of 40 mg/m(2) for 5-6 cycles. RESULTS: The 4-year actuarial survival was 74% for the CCRT group and 68% for the RT group (p = 0.60). The 4-year pelvic relapse-free survival was 87% for the CCRT group and 85% for the RT group (p = 0.37). The 4-year distant metastases-free survival was 75% for the CCRT group and 76% for the RT group (p = 0.44). The cumulative incidence of gastrointestinal and genitourinary injuries of grade 3 or above was 14.3% for the CCRT group and 7.9% for the RT group (p = 0.19). CONCLUSION: This study did not show a survival benefit of CCRT with weekly cisplatin and HDRICB for Stage II-III cervical cancer, nor did it demonstrate a significant increase of late complications when comparing with RT alone.     

Comparison of concurrent chemoradiation therapy with weekly cisplatin versus monthly fluorouracil plus cisplatin in FIGO stage IIB-IVA cervical cancer

Objective

Concurrent chemoradiation therapy (CCRT) is the standard treatment for locally advanced cervical cancer. Although the optimal chemotherapeutic regimen is not yet defined, previous randomized trials have demonstrated that 5-fluorouracil (5-FU) plus cisplatin every 3 weeks and weekly cisplatin are the most popular regimens. The purpose of this study was to compare the outcomes of weekly CCRT with cisplatin and monthly CCRT with 5-FU plus cisplatin for locally advanced cervical cancer.

Methods

We retrospectively reviewed data from 255 patients with FIGO stage IIB-IVA cervical cancer. Patients were classified into two CCRT groups according to the concurrent chemotherapy: weekly CCRT group, consisted of CCRT with weekly cisplatin for six cycles; and monthly CCRT group, consisted of CCRT with cisplatin and 5-FU every 4 weeks for two cycles followed by additional consolidation chemotherapy for two cycles with the same regimen.

Results

Of 255 patients, 152 (59.6%) patients received weekly CCRT and 103 (40.4%) received monthly CCRT. The mean follow-up period was 39 months (range, 1 to 186 months). Planned CCRT was given to 130 (85.5%) patients in weekly CCRT group and 84 (81.6%) patients in monthly CCRT group, respectively. Severe adverse effects were more common in the monthly CCRT group than in the weekly CCRT group. There were no statistically significant differences in progression-free survival and overall survival between the two groups (p=0.715 and p=0.237).

Conclusion

Both weekly CCRT and monthly CCRT seem to have similar efficacy for patients with locally advanced cervical cancer, but the weekly cisplatin is better tolerated.

Acute toxicity of cyclooxygenase-2 inhibitor rofecoxib as a radiosensitizer for concurrent chemoradiation in the treatment of uterine cervical cancer

Objective

To evaluate the acute toxicity of rofecoxib during concurrent use with cisplatin-based chemoradiotherapy (CCRT) in patients with cervical cancer.

Methods

We evaluated 67 FIGO stage IB2-IVA cervical cancer patients treated with CCRT between June 2002 and July 2004. The study group included patients who received rofecoxib (N=30) and the control group included patients who received CCRT only (N=37). The patients'' medical records were retrospectively reviewed for patient characteristics, toxicity related to CCRT and treatment results.

Results

There were no significant differences in toxicity between the two groups. The most common acute grade 3/4 toxicity was neutropenia (13.3% in the study group and 21.6% in the control group). Grade 3/4 late toxicity was observed in 2 (6.6%) patients in the study group and 3 (8.1%) in the control group. There was no treatment-related deaths in either group. Six (20.0%) patients in the study group had treatment failure. In the control group, 6 (16.2%) patients experienced treatment failure. Progression-free and overall survival was 55.8±4.2 and 59.0±2.8 months, respectively, in the study group, and 69.7±4.3 and 71.6±3.6 months, respectively, in the control group. There were no differences in progression-free and overall survival between the 2 groups.

Conclusion

Our data indicate that rofecoxib, at a dose of 25 mg twice daily, has acceptable acute toxicity as a radiosensitizer during CCRT. Although rofecoxib was not efficacious as a radiosensitizer in the present study, the benefit of rofecoxib as a radiosensitizer should be further evaluated in a prospective study.

伴中危风险因素ⅠB~ⅡA期宫颈鳞癌辅助化疗与同步放化疗预后的前瞻随机对照研究

目的 比较辅助化疗与同步放化疗对伴中危风险因素ⅠB~ⅡA期宫颈鳞癌患者预后的影响，探讨术后辅助化疗的安全有效性。方法 选取广西医科大学附属肿瘤医院190例患者，随机分为两组：单纯化疗组（CT组95例）和同步放化疗组（CCRT组95例），失访10例。生存率计算和生存曲线比较采用Kaplan-Meier生存分析法和Log rank检验，并采用Cox比例风险回归模型进行多因素分析。结果 中位随访36.7月，主要终点可评估的患者共180例。分别有3.30%（CT组）及10.11%（CCRT组）的患者出现了G3/G4级的血液学不良反应（P=0.019）；4.40%（CT组）及17.98%（CCRT组）的患者出现了严重的胃肠道不良反应（P=0.000），22.48%发生放疗相关的反应。两组间的局部复发率（P=0.317）及远处复发率（P=0.224）差异无统计学意义。PFS及OS在两组间亦无显著的统计学差异。结论 伴中危风险因素ⅠB~ⅡA期宫颈鳞癌患者术后化疗与同步放化疗的疗效无显著差别，但不良反应较同步放化疗显著减少。     

The efficacy of concurrent cisplatin and 5-flurouracil chemotherapy and radiation therapy for locally advanced cancer of the uterine cervix

Objective

To evaluate the efficacy of concurrent chemoradiation (CCRT) using 5-flurouracil (5-FU) and cisplatin for locally advanced cervical cancer.

Methods

We reviewed the medical records of 57 patients with locally advanced cervical cancer (stage IIB-IVA and bulky IB2-IIA tumor) who underwent the CCRT at Dong-A University Hospital from January 1997 to June 2007. The CCRT consisted of 5-FU, cisplatin and pelvic radiation. Every three weeks, 75 mg/m² cisplatin was administered on the first day of each cycle and 5-FU was infused at the dose of 1,000 mg/m²/d from the second day to the fifth day of each cycle. Radiation was administered to the pelvis at a daily dose of 1.8 Gy for five days per week until a medium accumulated dose reached to 50.4 Gy. If necessary, the radiation field was extended to include paraaortic lymph nodes. Consolidation chemotherapy was performed using 5-FU and cisplatin.

Results

Fifty-seven patients were enrolled and the median follow-up duration was 53 months (range 7-120 months). The overall response rate was 91.5% (74% complete response and 17.5% partial response). The 5-year overall survival and 3-year progression free survival rates were 69.4% and 74.9%, respectively. During the follow-up period (median 23 months, range 7-60 months), fourteen patients were diagnosed as recurrent disease.

Conclusion

CCRT with 5-FU and cisplatin which is the primary treatment for patients with locally advanced cervical cancer was effective and well tolerated.     

早中期巨块型子宫颈癌术前同步放化疗的临床研究

 目的 研究早中期巨块型子宫颈癌进行同步放化疗（CCR）后再接受根治性手术治疗的可行性和疗效，分析影响有残余肿瘤患者的预后因素。方法 随机选取了2001年1月至2003年9月Ⅰb2、Ⅱa、Ⅱb巨块型（宫旁内1／3受浸）子宫颈癌35例，子宫颈肿瘤≥4 cm，手术前10 MV X线全盆前后野常规放疗，总剂量3060 cGy17次；在放疗开始的前96 h和最后96 h，用5-氟尿嘧啶（5-Fu） 4 g静脉滴注，在放疗第1、8、15、22天分别用顺铂（DDP）20 mg／m2静脉滴注；休息4周，接受根治性子宫切除和盆腔淋巴结清扫术。结果 35例临床完全缓解（CR）率54.29 %，临床部分缓解（PR）率31.43 %，临床总有效率（CR+PR）85.71 %。手术后病理显示子宫颈标本中无残余肿瘤16例，有残余肿瘤19例，病理CR率45.71 %。35例3年总生存率为87.14 %。同步放化疗后有残余肿瘤患者的3年生存率为76.32 %，明显低于无残余肿瘤患者，3年生存率为100.00 %（P = 0.0358）；手术后病理显示浸润至浅肌层和浸润至外膜者3年生存率分别为100.00 %、41.67 %（P = 0.0109），差异有统计学意义；有脉管瘤栓与无脉管瘤栓者3年生存率分别为0和85.29 ％，差异有统计学意义（P＝0.0148）。结论 术前全盆外照射加同步化疗治疗巨块型早中期子宫颈癌近期疗效较好，并发症可耐受；肿瘤残余情况是影响预后的重要因素，并为手术后的个体化治疗提供了信息。     

热疗联合放化疗治疗局部晚期宫颈癌的远期疗效分析

目的:探讨热疗联合放化疗治疗晚期宫颈癌的远期疗效及晚期毒副反应。方法:收集2012年6月至2014年6月我院收治的局部晚期宫颈癌患者91例,分为两组:44例放化疗组和47例热放化疗组。对两组的5年总生存及晚期毒副反应进行比较。结果:热放化疗组5年总生存率略高于放化疗组（72.9%vs 65.4%）,但差异无统计学意义（P=0.455）。热放化疗组可降低晚期放射性直肠炎的发生率（P=0.042）。结论:热疗联合放化疗可降低晚期放射性肠炎,与放化疗相比有望提高远期生存率,需扩大样本量进一步研究。
