Operable stage IB and II cancer of the uterine neck: retrospective comparison between preoperative utero-vaginal curietherapy and initial surgery followed by radiotherapy]

PURPOSE: To identify prognostic factors and treatment toxicity in a series of operable stages IB and II cervical carcinomas. PATIENTS AND METHODS: Between May 1972 and January 1994, 414 patients (pts) with cervical carcinoma staged according to the 1995 FIGO staging system underwent radical hysterectomy with (n = 380) or without (n = 34) bilateral pelvic lymph node dissection. Lateral ovarian transposition to preserve ovarian function was performed on 12 pts. The methods of radiation therapy (RT) were not randomised and depended on the usual practices of the surgical teams. Group I: 168 pts received postoperative RT (64 pts received vaginal brachytherapy alone [mean total dose (MD): 50 Gy], 93 pts had external beam pelvis RT (EBPRT) [MD: 45 Gy over 5 weeks] followed by vaginal brachytherapy [MD: 20 Gy], and 11 pts had EBPRT alone [MD: 50 Gy over 6 weeks]. Group II: 246 pts received preoperative utero-vaginal brachytherapy [MD: 65 Gy], and 32 of theses 246 pts also received postoperative EBPRT [MD: 45 Gy over 5 weeks] delivered to the parametric and the pelvic lymph nodes with a midline pelvic shield. The mean follow-up was 106 months. RESULTS: The 10-year disease-free survival (DFS) rate was 80%. From 75 recurrences, 35 were isolated locoregional. Multivariate analysis showed that independent factors decreasing the probability of DFS were: both exo and endocervical tumour site (p = 0.047), lymph-vascular space invasion (p = 0.041), age < or = 51 yr (p = 0.013), 1995 FIGO staging system (stage IB1 vs stage IIA, p = 0.004, stage IB1 vs stage IB2, p = 0.0009, and stage IB1 vs stage IIB with 1/3 proximal parametrical infiltration, p = 0.00002), and histological pelvic involved lymph nodes (p = 0.00009). Methods of adjuvant RT did not influence the probability of DFS (group I vs group II, p = 0.10). The postoperative complication rate was 10.2% in group I and 8.9% in group II (p = 0.7) but the postoperative urethral complication rate necessitating surgical intervention with reimplantation was lower in group I than in group II (0.6% vs 2.3%, respectively, p = 0.03). The 10-year rate for grade 3 and 4 late radiation complications according to the LENT-SOMA scoring system was 10.4%. EPRT significantly increased the 10-year rate for grade 3 and 4 late radiation complications (yes vs no: 22% vs 7%, respectively, p = 0.0002). CONCLUSION: In our series, the methods of adjuvant RT (primary surgery vs preoperative uterovaginal brachytherapy) do not seem to influence the prognosis of the stage IB, IIA, and IIB (with 1/3 proximal parametrical involvement only) cervical carcinomas. The postoperative EPRT applied according to histopathological risk factors after surgical treatment increases the risk of late radiation complications.     

Analysis of the Curative Effect of Preoperative Intra-Arterial Infusion Chemoembolization on Stage,IB2-IIB Uterine Cervix Cancer

OBJECTIVE To investigate the short-term and long-term therapeutic efficacy of preoperative intra-arterial infusion chemo-embolization on stage IB2-IIB Uterine cervix cancer (UCC). METHODS A total of 143 patients with Stage IB2-lIB UCC were divided into a clinical trial group and a control group. The patients in the clinical trial group (n/=86) were treated with a combined therapy, i.e. preoperative intra-arterial infusion chemo-embolization, surgical therapy and postoperative radiotherapy, and those in the control group(n=57)were given surgical therapy and post-operative radiotherapy. The adverse effects, changes in local lesion and pathological examinations of the cancer, and the state during the surgery were observed after the intra-arterial infusion chemo-embolization. The survival rate and recurrence rate between the two groups were compared. RESUITS The total effective rate of the intra- arterial infusion chemo-embolization on Stage IB2-IIB UCC was 93.02%. The treatment could reduce tumor size, bring about retro-conversions of the clinical stage of the tumors and pathological grade of the cancer cells, and decrease the quantity, of intra-operative blood loss as well as the operating time. It could significantly improve the 5-year survival rate (P<0.05), and reduce the 2 and 5-yeartumor recurrence rates(P<0.05). Moreover, its side effects were little. CONCLUSIOAN Preoperative intra-arterial infusion chemo-embolization can create conditions for radical operation, lower the postoperative recurrence rate, and improve the prognosis in the patients with UCC. It is an effctive therapy in treating UCC.

Operable Stages IB and II cervical carcinomas: a retrospective study comparing preoperative uterovaginal brachytherapy and postoperative radiotherapy

PURPOSE: To evaluate our data concerning prognostic factors and treatment toxicity in a series of operable cervical carcinomas. METHODS AND MATERIALS: Between May 1972 and January 1994, 414 patients with cervical carcinoma, staged according to the 1995 FIGO staging system (286 Stage IB1, 38 Stage IB2, 56 Stage IIA, and 34 Stage IIB with 1/3 proximal parametrial involvement), underwent radical hysterectomy with (n = 380) or without (n = 34) bilateral pelvic lymph node dissection (N+: n = 68). Group I included 168 patients who received postoperative radiation therapy (RT): 64 patients had low-dose-rate vaginal brachytherapy with a median total dose (MTD) of 50 Gy; 93 patients had external beam pelvic RT (EBPRT) with an MTD of 45 Gy over 5 weeks, followed by low-dose-rate vaginal brachytherapy (MTD: 20 Gy); and 11 patients had EBPRT alone (MTD: 50 Gy over 6 weeks). Group II included 246 patients treated with preoperative low-dose-rate uterovaginal brachytherapy (MTD: 65 Gy); 32 of these 246 patients also received postoperative EBPRT (MTD: 45 Gy over 5 weeks) delivered to the parametria and pelvic nodes. Mean follow-up from the beginning of treatment was 106 months. RESULTS: First events included isolated locoregional recurrences (35 patients), isolated distant metastases (27 patients), and locoregional recurrences with synchronous metastases (13 patients). The 10-year disease-free survival (DFS) rate was 88% for Stage IB1, 44% for Stage IB2, 65% for Stage IIA, and 48% for Stage IIB. Multivariate analysis showed that independent factors influencing the probability of DFS were as follows: cervical site (exocervical or endocervical vs. both endo- and exocervical, relative risk [RR]: 1.77, p = 0.047), vascular space invasion (no vs. yes, RR: 1.95, p = 0.041), age (>51 years vs. 1 cm: 83% vs. 41%, respectively, p = 0.001). The overall postoperative complication rate was 10% in Group I and 9% in Group II (p = 0.7). The rate of postoperative ureteral complications requiring surgical intervention was lower in Group I than in Group II (0.6% vs. 2.3%, respectively, p = 0.03). The overall 10-year rate for Grade 3 and 4 late radiation complications was 10.4%. Postoperative EBPRT significantly increased the 10-year rate for Grade 3 and 4 late radiation complications (yes vs. no: 22% vs. 7%, respectively, p = 0.0002). CONCLUSION: The prognosis for patients with cervical carcinoma was not influenced by the sequence of adjuvant RT (preoperative uterovaginal brachytherapy vs. postoperative RT) for Stages IB, IIA, and IIB with 1/3 proximal parametrial involvement. However, postoperative EBPRT increased the risk of late radiation complications.     

Survival and prognostic factors comparing stage IB 1 versus stage IB 2 cervical cancer treated with primary radical hysterectomy

This study was undertaken to compare the survival rates of stage IB 1 versus stage IB 2 cervical cancer patients and to evaluate the prognostic factors after treatment primarily with radical hysterectomy and pelvic lymphadenectomy (RHPL). Patients with stage IB cervical cancer undergoing primary RHPL at Chiang Mai University Hospital between January 2002 and December 2009 were evaluated for survival and recurrence. Clinicopathological variables were analyzed to identify the prognostic factors affecting the survival of the patients. During the study period, RHPL was performed on 570 stage IB 1 and 110 stage IB 2 cervical cancer patients. With a median follow-up of 48 months, the 5-year disease-free survivals were 98.1% and 82.8% respectively (p<0.001). Multivariate analysis identified four significant prognostic factors affecting survival including sub-staging, non-squamous cell carcinoma histology, lymph node metastasis and the presence of lymph-vascular space invasion. In conclusion, with a primary radical hysterectomy, stage IB 1 cervical cancer patients have a significantly better survival rate than those with stage IB 2. Significant prognostic factors for stage IB cervical cancer include tumor histology, nodal status, and the presence of lymph-vascular space invasion.

目的 回顾性分析宫颈癌患者术后放疗的疗效、晚期副反应及预后因素.方法 搜集2005年2月前6年接受术后放疗的ⅠA～ⅡB期官颈癌病例114例,其中年龄24～72岁(中位值42.5岁);FIGO临床分期ⅠA期6例、Ⅰb1期51例、Ⅰb2期18例、ⅡA期26例、ⅡB期13例;术后病理为鳞癌92例、腺癌19例、腺鳞癌2例、未分化癌1例.113例采用加速器6、15 MV X线盒式4个野常规放疗40～60 Gy(中位值50 Gy),81例放疗后4周加192Ir近距离治疗,参考点在阴道黏膜下T0.5 cm,1～6次,4～30Gy(中位值16 Gy).87例接受术前或(和)同步增敏化疗.随访5～75个月(中位值20个月),总随访率为92%.结果 2年总生存率、无瘤生存率、盆腔控制率分别为93.1%、88.1%、94.6%,5年总生存率、无瘤生存率、盆腔控制率分别为75.7%、62.3%、85.6%.淋巴结转移及阴道残端阳性为总生存率的独立预后因素,阴道残端阳性为盆腔控制率的独立预后因素,分期、子宫下段受累及阴道残端阳性为无瘤生存率的独立预后因素.16例患者远处转移,最常见转移部位为肺、腹股沟及骨、肝及脑.RTOG分级晚期直肠反应发生率1级11.4%、2级11.4%、3级3.5%,泌尿系反应发生率1级14.0%、2级6.1%、3级0.9%.治疗后出现下肢水肿者8例.结论 术后放疗在盆腔控制率上能达到较满意疗效,且放疗相关晚期副反应是可接受的,远处转移是致死主要问题.
