A prospective randomized study in selected patients with Stage IB and IIA carcinoma of the uterine cervix was carried out at Washington University between January 1966 and December 1979. Patients were randomized to be treated with irradiation alone consisting of 1000 cGy whole pelvis, additional 4000 cGy to the parametria with a step wedge midline block, and two intracavitary insertions for 7500 mgh; or irradiation and surgery, consisting of 2000 cGy whole pelvis irradiation, one intracavitary insertion for 5000-6000 mgh followed 2 to 6 weeks later by a radical hysterectomy with pelvic lymphadenectomy. A total of 40 patients with Stage IB and 16 with Stage IIA were randomized to be treated with irradiation alone. A similar group of 48 patients with Stage IB and 14 with IIA were randomized to the preoperative radiation and surgery group. The 5-year, tumor-free actuarial survival for Stage IB patients treated with radiation was 89% and with preoperative radiation and surgery 80%. In Stage IIA, the tumor-free actuarial 5-year survival was 56% for the irradiation alone group and 79% for the patients treated with preoperative radiation and radical hysterectomy. In the patients with Stage IB treated by irradiation alone only one pelvic failure combined with distant metastasis occurred, and 3 patients developed distant metastasis. In the 48 patients treated with combined therapy, there were six pelvic failures (12.5%) all combined with distant metastases and two distant metastases alone. In the 16 patients with Stage IIA treated with radiotherapy alone, there were four pelvic failures (all parametrial), three of them combined with distant metastasis. In the 14 patients treated with irradiation and surgery, two developed a pelvic recurrence, and one distant metastasis. In the preoperative radiation group, the incidence of metastatic pelvic lymph nodes was 6.3% in Stage IB and 7.1% in Stage IIA. Major complications of therapy in the patients treated with radiation alone (10%) consisted of one rectovaginal fistula, two vesicovaginal fistulas, and one rectal stricture. In the preoperative radiation group, three ureteral strictures and two severe proctitis-rectal strictures were noted (8%). The present study shows no significant difference in therapeutic results or morbidity for invasive carcinoma of the uterine cervix Stage IB or IIA treated with irradiation alone or combined with a radical hysterectomy and lymphadenectomy.  相似文献

To compare the results of treatment in stage IIB squamous cell carcinoma of the uterine cervix of two treatment regimens, two radium insertions vs one insertion, a prospective randomized study was carried out at Ramathibodi Hospital from 1 January 1983 to 31 December 1986, and the results were evaluated at the end of March 1991. The patients in treatment I (90 cases) received 40-41.4 Gy whole pelvic external irradiation and two intracavitary radium insertions, while patients in treatment II (53 cases) received 50.0-50.4 Gy and one intracavitary insertion. Both groups received the same total dose at point A, about 85-90 Gy. At 4 and 5 years, by the Kaplan-Meier survival curve, the disease-free survivals were 76 and 76% vs 79 and 79%, respectively, in treatment I and treatment II, which showed no significant difference by the log-rank test. Both groups had comparable serious complication rates, 0% vs 1.9%, respectively. However, grade I complications in treatment II, 35.8%, were higher than those in treatment I, 17.8% (P less than 0.01). Therefore, we concluded that treatment II provided the same disease-free survival and a very low rate of serious complications. To replace treatment I, the dose at the rectum and urinary bladder should be maintained with caution.  相似文献

PURPOSE: To compare treatment outcome results of conventional surgery vs. radiotherapy (RT) for carcinoma of the uterine cervix. MATERIALS AND METHODS: A retrospective analysis was conducted of 152 patients with uterine cervical cancer radically treated with surgery or high dose-rate intracavitary brachytherapy (HDR-ICBT) with or without external RT from June 1991 to May 2004. The median follow-up time was 43.5 months (range, 1.0-130.0 months). The median age was 53 years (range, 25-81 years). There were 13 patients (9%) in stage IA, 52 (34%) in stage IB, 24 (16%) in stage IIA, and 63 (41%) in stage IIB. The conventional surgery group included 115 patients (76%) who underwent hysterectomy with pelvic lymph node dissection. Of these, 72 (63%) received postoperative radiotherapy. Thirty-seven patients (24%) were assigned to the RT group. Of these, 14 (38%) received chemoradiotherapy. Three patients with stage I received ICBT-alone without external beam irradiation. RESULTS: The 5-year cause-specific survival (CSS) rates for surgery and RT were 79.9% and 82.3%, respectively; the difference between these two treatments was not statistically significant (P = 0.8524). The differences in the survival rates between the two treatments for each of the stage I or stage II patients were also not statistically significant (P = 0.8407 for stage I and P = 0.6418 for stage II). CONCLUSIONS: This retrospective study suggests that RT results in compatible survival with conventional surgery for patients with stage I-II cervical carcinoma.  相似文献

Ten patients with advanced and previously untreated squamous cell carcinoma of the cervix were treated with a synchronous course of radiotherapy (RT) and chemotherapy (CT). RT consisted of 3600 to 4500 cGy external pelvic treatments on a 6-MeV linear accelerator followed by two intracavitary applications administering a total of 4000 mg hr of radium equivalent cesium. CT consisted of a course of mitomycin C (10 mg/m2 iv bolus) and 5-fluorouracil (5FU; 1000 mg/m2/24 hr for 96 hr) during the second week of external RT and another course of cis-platinum (CDDP; 75 mg/m2, 1-6 hr infusion) and 5FU (1000 mg/m2/24 hr for 96 hr) during the first intracavitary cesium application. Toxicity was acceptable and complete clinical response was obtained in all patients at the end of the regimen. Nine patients are alive (eight without disease) 6 to 37 months following initiation of treatment (median 20 months). One patient has developed lumbar spine bone metastases and another died of local and pulmonary disease at 28 months. This combination of 5FU/mitomycin C/CDDP and RT appears to be a practical, well-tolerated, and highly effective regimen for advanced cervical carcinoma.  相似文献

An analysis is made of the results of treatment of 96 women with carcinoma of the cervix, Stages IB and II, in a private practive. All 96 women were treated preoperatively with uterine intracavitary radium, followed 6 weeks later by Wertheim hysterectomy with pelvic lymphadenectomy. If malignant tumor was present in the lateral pelvic lymph nodes, external radiation was given postoperatively. The over-all survival rates were: Stage IB, 88% and 84% at 5 and 10 years; Stage II, 72% and 62% at 5 and 10 years. Regardles of the clinical stage, the highest survival rates were found in those patients who had no malignancy in the lateral pelvic lymph nodes and no residual cervical carcinoma. The lowest survical rates were found in those patients who had both residual cervical carcinoma and lymph node metastases.  相似文献

Thirty-eight patients with Stage I and II uterine carcinosarcoma were treated by surgery with and without whole-pelvic irradiation (WPI) at our institution from 1975 to 1993. Ten patients (8 Stage I and 2 Stage II) were treated with surgery alone, while 28 patients (20 Stage I and 8 Stage II) received WPI in addition to surgery. With a median follow-up of 75 months (range 25–220 months), a trend toward a decreased rate of pelvic recurrence in those receiving WPI (6/28, 21%) compared to those treated with surgery alone (5/10, 50%) was observed (P= 0.09). There was no difference in the rate of distant recurrence between those receiving WPI (12/28, 43%) and those who did not (4/10, 40%) (P= 0.9). There was also no difference in the 2- and 5-year Kaplan–Meier survival estimates for the patients receiving WPI (79 and 59%, respectively) compared to those who did not receive WPI (60 and 60%, respectively) (P= 0.84). In this small series, the addition of whole-pelvic irradiation to primary surgery did not improve survival; however, a trend toward improved pelvic control was observed, suggesting a possible benefit for pelvic irradiation that should be studied in future trials.  相似文献

Pelvic exenteration, University of Michigan: 100 patients at 5 years   总被引:5,自引:0,他引:5  
One hundred patients undergoing pelvic exenteration (total 69, anterior 13, posterior 18) at the University of Michigan Medical Center from 1964-1984 are reported. All patients were followed for at least 5 years or until time of death. The overall cumulative survival was 66% at 3 years and 61% at 5 years. The age of the patients ranged from 21-74 years (median 53). The type of pelvic neoplasm included squamous cell of the cervix, 57; adenocarcinoma of the cervix, nine; squamous cell carcinoma of the vulva, 12; squamous cell carcinoma of the vagina, eight; vaginal sarcoma, four; adenocarcinoma of the vagina, one; adenocarcinoma of the endometrium, four; uterine sarcoma, four; and adenocarcinoma of the ovary, one. The cumulative 5-year survival was significantly related to the presence of metastatic disease to the regional lymph nodes (8% 3-year and 0% 5-year survival), time interval from primary diagnosis to exenteration (within 1 year 44%, 1-10 years 60%, and over 10 years 95%), and cell type (squamous cell 68%, sarcoma 62%, and adenocarcinoma 26%). Patients with squamous cell carcinoma of the cervix (N = 57) had a cumulative 5-year survival of 73%, compared with nine patients with adenocarcinoma of the cervix, who had a 22% 5-year survival. No significant difference in survival existed for the type of exenteration, original stage of squamous cell cervical carcinoma, size of recurrent squamous cell lesion, or age of the patient. Early or late complications occurred in 49 patients. Two patients died in the postoperative period. Small-bowel obstruction was the most common complication seen in this series.  相似文献

Summary: Combined methods of treatment of carcinoma of the cervix Stage 1B and 2 (A and B) are described using irradiation and surgery. In a personally conducted series of 101 patients, a.5-year survival rate of 86% for Stage 1 and 65.4% for Stage 2 was achieved. The urinary tract morbidity associated with combined methods of treatment and the modifications adopted to prevent it are described. It is concluded that the preferred method of treatment of carcinoma of the cervix Stages IB, 2A and 2B is irradiation (intracavitary + external megavoltage irradiation) followed by modified radical hysterectomy.  相似文献

Locally advanced cervical cancer has a dismal prognosis, with a high local failure rate and a poor survival rate. To improve the cure rate for advanced carcinoma of the cervix, we initiated a study of intra-arterial (I-A) chemotherapy with cisplatin via the uterine artery prior to definitive radiotherapy. I-A chemotherapy via the internal iliac artery has been used to treat advanced cervical cancer; however, access by way of the uterine artery has not been tested for this purpose. Thirty-four patients with central tumor ≥5 cm in anteroposterior diameter observed on CT scans were treated with I-A chemotherapy. I-A chemotherapy consisted of unilateral catheterization of the uterine artery using 120 mg/m2cisplatin. After assessment of I-A chemotherapy, all but 3 patients were treated with a combination of whole-pelvis external irradiation and intracavitary irradiation. The 3 patients underwent external radiotherapy alone. Twenty-seven of 34 patients treated were evaluable for response to I-A chemotherapy. Eleven patients (41%) experienced a partial response. Seventy-six percent of the 34 patients treated with I-A chemotherapy followed by radiotherapy exhibited a complete response by the end of treatment. Toxicity was well tolerated and no death due to treatment occurred. The 2- and 5-year actuarial survival rates were 64 and 55%, respectively. The crude incidences of pelvic recurrence and distant metastasis observed at a median follow-up of 54 months were both 47%. This study for locally advanced cervical cancer suggests there is benefit to be derived from our I-A chemotherapy followed by radical radiotherapy.  相似文献

This is a retrospective analysis of 148 patients with histologically proven carcinoma of the cervix, stage III, treated with irradiation. All patients received external irradiation with cobalt 60 followed by intracavitary radium application. The median age was 55 years. Squamous cell carcinoma was found in 96.5% of the cases. The 8-year actuarial survival rate was 41%. Bilateral parametrial invasion proved to be a strong prognostic factor. Patients with unilateral disease had a survival rate of 43% whereas in those with bilateral involvement it was only 15% (P less than 0.005). The total pelvic failure rate was 29.5%. The overall incidence of distant metastasis was 11%. The complication rate (minor and major complications) was high, with vaginal stenosis (22.5%), proctitis (21.5%), cystitis (13.5%), and fistulae (4%) occurring in 33, 32, 20, and 6 patients, respectively. New treatment modalities are urgently needed for advanced carcinoma of the cervix. Bilateral parametrial involvement is an unfavorable prognostic factor and this should be kept in mind when designing new protocols.  相似文献

A comparison of the 5-year relative survival rates has been made between cases of cancer of the uterine cervix treated with 226Ra low-dose-rate intracavitary irradiation and those treated with 60Co high-dose-rate intracavitary irradiation (using the remote afterloading system, RALS). External irradiation using LINAC was also administered in both groups. The 5-year relative survival rates of the low-dose-rate cases were 82.6, 55.4, 49.0, and 18.2% in stage I, II, III, and IV cases, respectively, whereas they were 97.4, 55.1, 56.8, and 29.0% in the respective high-dose-rate cases. The differences between the two groups were not statistically significant. Delayed radiation complications of the rectum were frequent in both groups (approximately 14%) and those of the urinary bladder were somewhat less frequent (approximately 8%). The incidence of such complications did not differ significantly between the two groups.  相似文献

OBJECTIVES: To evaluate the toxicity and the efficacy of paclitaxel/carboplatin chemoradiotherapy as a definitive treatment for squamous cell cancer of the uterine cervix. METHODS: From March 2000 to January 2004, 33 patients with squamous cell cancer of the uterine cervix were treated with concurrent chemoradiotherapy including 2 cycles of paclitaxel (135 mg/m(2)) and carboplatin (area under the time-concentration curve 4.5 mg min/ml) at 4-week interval. Seven patients received adjuvant chemotherapy with the same chemotherapeutic regimen. All patients received external beam radiotherapy with 41.4-51.4 Gy (median 50.4 Gy) to the whole pelvis. Twenty-eight patients received boost irradiation to the cervix by brachytherapy with 25.6-43.3 Gy (median 34.6 Gy) and 5 patients by external beam radiotherapy with 10.8-14.4 Gy (median 14.4 Gy). RESULTS: A median follow-up period was 27 months (range: 6-53 months). Acute hematological toxicity of grade 3 or 4 developed in 20 patients (61%), and acute gastrointestinal toxicity of grade 3 developed in 1 patient (3%). Vesicovaginal fistula occurred in 2 patients (6%). All patients achieved objective response (CR 70%, PR 30%) in 2 months after termination of treatment. One patient had a local progression in cervix, and 4 patients developed distant metastases. The 3-year estimated disease-free survival rates for stages I-IIA, IIB, III and IV were 67%, 91%, 88% and 50%, respectively. The 3-year estimated survival rates for stages I-IIA, IIB, III and IV were 89%, 91%, 88% and 50%, respectively. CONCLUSION: Concurrent chemoradiotherapy with paclitaxel and carboplatin is effective to achieve an excellent pelvic control.  相似文献

The metastatic potential patterns of dissemination have been investigated in 150 patients with Stage 1B adenocarcinoma of the cervix treated during a 20-year period from 1956 to 1977. All cases with the exception of one were treated with a combination of intracavitary radium implants followed by a radical surgical procedure with pelvic lymph node dissection. It was found that the incidence of pelvic metastases and distant recurrences and the survival rates were the same as in previously published reports for squamous cell carcinomas treated in the same manner. In one respect adenocarcinomas showed a significant difference when compared with squamous cell cancers: The incidence of residual tumor in the hysterectomy specimens after intracavitary treatment was much higher (30% versus 11%). This is considered a strong argument for surgical treatment of patients with early stages of adenocarcinoma of the cervix.  相似文献

Forty-eight patients with FIGO stage IVA cervix cancer were treated with radiation therapy at the Hunter Radiation Therapy Center, Yale--New Haven Hospital from 1966 to 1985. Nine of the 48 patients are alive without recurrence (NED) and the 5-year actuarial survival rate is 18% (+/- 6%, standard error). There was a substantial difference in outcome based on treatment technique. Thirty-five patients were treated with external beam (EB) plus intracavitary (IC) and 8 of these patients (23%) are NED. None of the 12 patients treated with EB alone are alive. One patient treated with preoperative EB plus exenteration is NED. The severe complication rate was 22% and most complications were vesicovaginal fistulas due to successful treatment for bladder involvement. There was a significant difference in survival for patients with minimal parametrial disease (stage IVA1) versus patients with significant parametrial disease (stage IVA2) which was defined as fixation to one or both pelvic sidewalls or hydronephrosis on IVP. The 5-year survival for stage IVA1 disease was 46% (+/- 14%) versus only 5% (+/- 4%) for stage IVA2 disease. Our results indicate that superior survival for stage IVA cervix cancer patients is associated with two factors: minimal parametrial disease and radiation treatment which combines EB plus IC.  相似文献

Objective.Management of locally advanced cervical cancer consists primarily of combination external and internal radiation. In order to investigate the impact of intracavitary brachytherapy versus interstitial brachytherapy on local tumor control, survival, and complications, we retrospectively reviewed the concomitant experience of two institutions, each of which practice exclusively one of these radiotherapeutic techniques.Methods.Between 1979 and 1989, 61 patients with bulky stage II, III, or IVA cervical cancer were treated using a combination of teletherapy and intracavitary brachytherapy at one institution, while 70 similar patients were treated with teletherapy and interstitial brachytherapy at another institution. Patients in both groups were similar with respect to age, FIGO stage, tumor size, surgical stage, and histologic subtype. Patients treated with intracavitary therapy received a mean cumulative dose of 7706 cGy to point A and 5523 cGy to point B using standard Fletcher–Suit techniques. Those who received interstitial irradiation were treated with a mean external dose of 5050 cGy and 2 interstitial implants using a transperineal Syed–Neblett template with a mean tumor dose of 2239 and 1,942 cGy with each application, respectively. Patients treated with chemoradiation were excluded from this review.Results.Although initial rates of local control were not different, prolonged 5-year disease-free survival (50% vs 21%,P= 0.01) and improved 5-year local control (61% vs 32%,P=0.01) were observed among patients with stage II disease treated with intracavitary irradiation. No statistical differences in survival could be detected among stage III and IVA patients. Women treated with intracavitary irradiation received a larger dose of brachytherapy than those treated with interstitial therapy (4608 vs 3504 radium milligram hours equivalent,P< 0.0001) because a tandem was only used in 17 (24%) interstitial implants. Major complications occurred in 21% of patients in each group.Conclusion.When a tandem is infrequently used during interstitial brachytherapy, the toxicity is similar to that of intracavitary techniques. However, more relapses are observed among patients with stage II lesions treated with interstitial irradiation.  相似文献

OBJECTIVE: We retrospectively reviewed our experience with concurrent chemoradiotherapy (CCRT) using high-dose-rate intracavitary brachytherapy (HDR-ICBT) to assess its feasibility and efficacy in the treatment of patients with uterine cervical cancer. METHODS: Forty patients with uterine cervical squamous cell carcinoma treated with CCRT using HDR-ICBT were analyzed. The median cervical tumor size assessed by MRI was 63 mm (range: 40-86 mm). Eighteen patients (45%) had enlarged pelvic nodes on MRI (> or =10 mm). Cisplatin (20 mg/m2/day) was concurrently administered with radiotherapy for 5 days at 21-day intervals for a median of three courses (range: 1-5 courses). Thirty-eight (95%) patients received whole pelvic external beam radiotherapy (EBRT) with 40 Gy/20 fractions followed by HDR-ICBT with 18 Gy/3 fractions to point A. Subsequently, additional pelvic EBRT with 10 Gy/5 fractions was delivered with a midline block. The cumulative biological effective dose (BED) at point A of this schedule was 77 Gy10. The median follow-up period for all 40 patients was 37 months (range: 8-71 months). RESULTS: Grade 3/4 leukopenia was the most common acute side effect (83%). The actuarial 3-year pelvic control rate, disease-free survival rate, and overall survival rate were 91%, 67%, and 79%, respectively. Eight (20%) patients suffered late gastrointestinal complications (all grades). No patient suffered radiation cystitis (all grades). Only one patient experienced grade 3 complication (enterocolitis). The actuarial 3-year late complication rate (all grades) was 9% for proctitis and 15% for enterocolitis. CONCLUSION: This preliminary study suggests that CCRT using HDR-ICBT is feasible and efficacious for patients with locoregionally advanced uterine cervical cancer.  相似文献

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.  相似文献

The present study involved 215 endometrial carcinoma patients. Ninety-nine were treated by combined irradiation and surgery (preoperative external irradiation and intracavitary insertion followed by total hysterectomy and lymphadenectomy). Radiotherapy alone was used with 116 patients i.e. whole pelvis external irradiation and Heyman radium packing (40 patients) or afterloading techniques with Fletcher-Suit-Delclos applicators and cesium (76-patients). The 5-year NED survival rate was 78.7% in the combined therapy group and 44% in the exclusive radiotherapy group. The locoregional recurrence rates were 10% in the combined group and 28% in the exclusive radiotherapy group. These results are discussed in relation to data in the literature and to biases introduced due to patient selection in this nonrandomized study. Five-year survival rates, locoregional recurrence rates and sites of failures are analyzed according to the different treatments. Modifications of the external irradiation and intracavitary techniques allowed us to obtain better results and fewer complications.  相似文献
