Stage II adenocarcinoma of the endometrium treated by two standard regimens of combined preoperative irradiation and surgery

We retrospectively analyzed 77 patients with stage II endometrial carcinoma treated with standard regimens of preoperative radiotherapy (RT) and surgery (S). The age range was 31–74 years with a median of 56.3 years. Thirty-three patients received 40 Gy whole pelvis RT followed by either radical or modified radical hysterectomy. Forty-four patients received 50 Gy whole pelvis RT and sequential intrauterine and intravaginal cesium-137 brachytherapy followed by a simple hysterectomy. Median follow-up was 111 months. No patient was lost to follow-up. The overall 5-year actuarial survival was 78%. There was no significant difference between the two treatment groups. Several prognostic variables were analyzed. Those with histologic grade I and II had 5-year survival of 89% and 83%, respectively, compared to 62% for grade III ( P =0.045). The 5-year survival for microscopic cervical involvement was 87% compared to 59% for gross involvement ( P = 0.008). Patients with negative or microscopic residual tumor in the surgical specimen and those with negative lymph nodes had less risk of treatment failure. Local failure occurred in only 9%. Major complications (3%) were seen only in the radical surgery group. Combined preoperative RT and S provide high cure rates with minimal complications for patients with stage II endometrial carcinoma. Patients with adverse prognostic factors are candidates for trials of more aggressive local and systemic therapy.     

Risk factors and prognosis in stage II endometrial cancer

Ninety-seven patients with Stage II endometrial cancer were analyzed by life table analysis for survival as a function of patient age, cell type, grade of tumor, depth of invasion, treatment, surgical stage, and extent of cervical involvement. The corrected 5-and 10-year survival was 65.9% and 57.9%, respectively. Cumulative 5-year survival of patients treated with radiation was 77.0%, with surgery 66.1%, and with combined therapy 58.5%. The extent of tumor, including depth of invasion, degree of cervical involvement, and presence of occult distant metastases, was most important in assessing prognosis. Of 36 patients without preoperative radiation, all those with superficial tumors lived at least 5 years, as compared with 57.9% of patients with deeply invasive tumors. These factors were less valuable in patients treated initially with radiation therapy where 30% of patients without residual tumor in the uterus died with recurrence within 5 years. The accuracy of endocervical curettage in determining cervical extension from an endometrial cancer and the patterns of recurrence were also analyzed. Less than half of patients with a normal-appearing cervix and positive endocervical curettage had tumor found in the nonirradiated hysterectomy specimen. There was poor correlation between the stage of disease and the extent of tumor found at operation. Agreement between the stage and operative findings was found in only half the patients treated initially with surgery.     

Invasive vaginal carcinoma: analysis of early-stage disease

From 1960 through 1987, 89 patients with stage I (44 patients) or II (45 patients) vaginal carcinoma (excluding melanomas) were treated primarily at the Mayo Clinic. Treatment consisted of surgery alone in 52 patients, surgery plus radiation in 14, and radiation alone in 23. The median duration of follow-up was 4.4 years. The 5-year survival (Kaplan-Meier method) was 82% for patients with stage I disease and 53% for those with stage II disease (p = 0.009). Analysis of survival according to treatment did not show statistically significant differences. This report is consistent with previous studies showing that stage is an important prognostic factor and that treatment can be individualized, including surgical treatment for primary early-stage vaginal cancer.

Adjuvant chemotherapy as treatment of high-risk stage I and II endometrial cancer

OBJECTIVE: This study was performed to define the subgroups of patients who benefit from postoperative adjuvant chemotherapy in stage I and II endometrial carcinoma. METHODS: A retrospective review of 170 International Federation of Gynecology and Obstetrics (FIGO) stage I and II endometrial carcinoma patients treated between 1988 and 2000 at Niigata University Hospital was performed. All patients underwent surgery, of which 41 patients underwent adjuvant chemotherapy, consisting of intravenous cisplatin, doxorubicin, and cyclophosphamide. Multivariate analysis was performed for the prognostic factors and actuarial techniques were used for the survival and recurrence rates. RESULTS: The patients were divided into low-risk and high-risk groups based on the number of prognostic factors (tumor grade G3, outer half myometrial invasion, lymph-vascular space involvement (LVSI), and cervical invasion). The 5-year disease-free survival and the 5-year overall survival for the low-risk group were 97.4%, and 100%, respectively, which were significantly better than 77.4% and 88.1% for the high-risk group (P < 0.0001, P < 0.0001), respectively. Among high-risk group patients, the 5-year disease-free survival and the 5-year overall survival were 88.5% and 95.2% in 26 patients treated with adjuvant chemotherapy, and 50.0% and 62.5% in eight cases who underwent only surgery (P = 0.0150, P = 0.0226). Disease recurrence occurred in 7 (20.6%) of 34 high-risk group patients. Four of seven recurrences occurred in patients who did not receive postoperative chemotherapy, in which all four were distant failure. In the remaining three patients who were in the CAP group, two had vaginal wall recurrence and only one had pulmonary recurrence. Three recurrences were also observed in the 133 low-risk group patients. Only isolated vaginal wall recurrence occurred in three patients without adjuvant chemotherapy after the initial surgery. CONCLUSIONS: There is possibility that postoperative adjuvant CAP may be omitted in surgical stage I or II endometrial cancer patients with 0 or 1 prognostic factor. The high-risk group of patients should be treated with postoperative adjuvant CAP to decrease distant failure and improve prognosis.     

Endometrial carcinoma: treatment and outcomes in the regional hospital setting

OBJECTIVE: Between 1986 and 2000, 204 cases of endometrial carcinoma were managed at Good Samaritan Hospital and Samaritan Regional Cancer Center, both located in Corvallis, Ore. Too often in the private practice setting, accurate outcome data and critical review of appropriateness of care are insufficient or lacking. The current review is the first in-depth examination of endometrial malignancies treated in Corvallis since the author's arrival in 1985. STUDY DESIGN: Data were retrieved through confidential review of hospital, Cancer Center, and office charts of all patients treated for endometrial carcinoma during the previous 15 years. RESULTS: Treatment modalities included surgery, radiation therapy, chemotherapy, hormonal therapy, and combinations thereof. Seventy-six percent of the cases were surgical stage I, 9% were stage II, 10% were stage III, and 5% were stage IV. Tumors were predominantly grade 1 or 2, which accounted for 69% of the total. Twenty-seven percent were grade 3 or undifferentiated. The overall 5-year disease-free survival was 86%. CONCLUSION: The outcomes for this patient population compare favorably with previously published survival data from larger studies.     

Clinical outcome in endometrial cancer

Patients with endometrial carcinoma (N = 1113) were treated by conventional therapy, using surgery and radiotherapy, complemented by daily administration of 100 mg oral medroxyprogesterone acetate (MPA) for a 2-year period. Only 7.3% of the malignancies were at an advanced clinical stage (III or IV), whereas 75.9 and 16.8% of the carcinomas were detected at clinical stages I and II, respectively. The 5-year survival rate was 71.0% overall, and 77.8%, 61.0, 29.0, and 5.3 for clinical stages I, II, III, and IV, respectively. Patients with anaplastic carcinoma (grade 3) at all clinical stages had significantly lower survival rates than had patients with well-differentiated (grade 1) and moderately differentiated (grade 2) adenocarcinomas. Death of grade 1, grade 2 and grade 3 endometrial carcinoma during the first 2 years occurred in 4.7, 6.8, and 18.2% of cases, respectively, in stage II, indicating that adjuvant MPA cannot totally prevent the progression of endometrial malignancy. The incidence of anaplastic endometrial carcinoma increased with the spread of the disease. It often appeared in patients with low body weight or a second invasive malignancy, but seldom occurred in young patients or patients with diabetes, uterine myoma, or a history of previous estrogen use. The worsened prognosis associated with old age, low body weight, and presence of a second invasive malignancy thus seems at lest partly due to the increased incidence of anaplastic carcinoma, which, on the other hand, did not contribute to the decreased 5-year survival rate of patients with diabetes or severe hypertension.     

Predictors of Recurrence in Surgical Stage II Endometrial Adenocarcinoma

OBJECTIVE: A retrospective review of surgical stage II endometrial carcinoma was performed to evaluate clinical course, treatment, recurrence rate, and survival. METHODS: A list of patients with clinical and surgical stage II endometrial carcinoma was obtained through the tumor registry and from the pathology department from 1988 to 1996. Data were collected on all cases of patients with endometrial carcinoma meeting stage II criteria by FIGO surgical staging. Variables including stage, histology, grade, lymph vascular space invasion (LVI), type and extent of surgery, radiation type and amount, smoking, menstrual status, parity, and age were evaluated for their predictive ability of disease recurrence. Cox proportional hazard regression models were used to examine the potential predictors of time to relapse univariately and multivariately. RESULTS: Of patients identified, 65 underwent primary surgical staging. Only adenocarcinomas were included. Mean follow-up time was 4.7 years (range 0.2-9.6 years). Postoperative radiation was given to 85.7% of patients. There were 10 patients (15.4%) with recurrence of disease with a mean time to recurrence of 25 months. Five-year disease-specific survival was 93%. The only significant predictor of time to relapse was LVI (P = 0.002) in the multivariate analysis. CONCLUSION: This retrospective review suggests that primary surgery followed by postoperative radiation therapy gives excellent results in surgical stage II disease. LVI appears to be a strong predictor of disease recurrence regardless of postoperative radiation therapy. It is difficult to draw conclusions about the type and amount of radiation given because recurrence rate is so low; however, it is reasonable to continue adjuvant radiation especially in cases where LVI is identified.     

Stage II endometrial carcinoma: 10-year follow-up of combined radiation and surgical treatment

Fifty-five patients with histologically confirmed stage II adenocarcinoma of the corpus uteri were treated with combined radiation therapy and surgery and followed for 2 to 10 years. The overall survival at 5 and 10 years is 75 and 56%, respectively; the age-adjusted survival is 93 and 73%, respectively. Disease-free survival is 88% at 2 years and 83% at both 5 and 10 years. Although 10 patients (18%) failed treatment, each local pelvic recurrence was accompanied by dissemination elsewhere. Histological grade and extent of involvement of the uterine cervix at time of examination under anesthesia are statistically significant prognostic factors. Age, depth of uterine sounding, and depth of myometrial invasion by tumor were not of prognostic value. We conclude that combined preoperative external beam and intracavity radiation with total abdominal hysterectomy and bilateral salpingo-oophorectomy is the preferred treatment for stage II endometrial carcinoma ecause of the excellent survival and low morbidity. Furthermore, both histologic grade and extent of cervical involvement predict the natural history of stage II disease.     

Current vulvar cancer treatment in Bulgaria

PURPOSE OF INVESTIGATION: Our aim was to outline the treatment of carcinoma of the vulva at the National Oncological Centre in Sofia, Bulgaria. METHODS: We examined the records of 250 patients over a 10-year period treated at the Gynaecologic-Oncology Clinic of our Centre. RESULTS: There were 130 patients (52%) treated with surgery and radiation. There were 120 patients (48%) treated by surgery only. Thirty of these patients were treated by pelvic exenteration with radical vulvectomy. The five-year survival rate was 36% - 12 patients. The 1-year survival rate for all patients was 80% - 200 patients. The five-year survival rate was 50%. DISCUSSION: We have results similar to other clinics in the world working in this field. We now emphasize external radiation for advanced disease but the treatment must be individualized. CONCLUSION: We have outlined the treatment of carcinoma of the vulva at our Centre, over a 10-year period.     

Prognostic factors and selective use of vaginal hysterectomy in early stage endometrial carcinoma

INTRODUCTION: Endometrial cancer represents the fourth most frequent malignancy in women of any age, tending to become the most common gynaecological tumor in developed Countries. A retrospective analysis has been conducted on the prognostic factors of endometrial neoplasm during 15-years experience (1977-1991). MATERIAL AND METHODS: 321 patients affected by stage I and II endometrial carcinoma have been treated surgically first hand. Surgical-pathological staging and prognostic factors were reviewed and related to follow-up and 5-year survival rate. RESULTS: The age-peak of patients was 50-70 years; prevalent histologic type was adenocarcinoma (95.6%); 269 patients were in stage I and 52 in stage II. In stage I disease overall 5-year survival rate resulted to be 81.4%, while in stage II it fell to 59.6%. DISCUSSION: Myometrial involvement by adenocarcinomatous cells is probably the most important prognostic factor, considering its reliability and non-contradictory evaluation. Our data confirm there is no difference in impact on 5-year survival between abdominal and vaginal routes in clinical stage I and occult stage II endometrial carcinoma.     

Pelvic irradiation for stage II ovarian carcinoma

Over a 20-year period, 34 patients with FIGO stage II ovarian carcinoma were treated with postoperative pelvic irradiation at the University of Michigan. Complications of radiation treatment were minimal. The overall actuarial disease-free 5-year survival was 53%. This was not significantly different for substages IIA, IIB, or IIC. Patients with well-differentiated tumors had a significantly better survival than patients with moderate or poorly differentiated tumors (P less than 0.05). The implications for managing stage II ovarian carcinoma are discussed.     

Clear-cell and papillary serous cancer: treatment options

Clear-cell carcinoma (CCC) and serous papillary carcinoma of the endometrium (UPSC) are rare subtypes of endometrial carcinoma (10%). The histological diagnosis can be made on the dilation and curettage specimens in both types in a very high percentage of the cases. This is important in the planning of treatment. CCC and UPSC are associated with about 50% of all relapses occurring in endometrial carcinoma, and the 5-year survival rate is, on average, 42% and 27% respectively. Surgico-pathological stage, age, and vessel invasion are independent prognostic factors for both groups. The recurrence rate is extremely high, and the most frequent extra-pelvic sites of relapse are the upper abdomen, lungs and liver. Stage Ia patients treated with complete surgical staging alone have a low risk of relapse and need not be offered adjuvant systemic therapy or pelvic radiation. The treatment of patients with CCC and UPSC stage Ib, Ic, II and III should include radical debulking surgery and some form of adjuvant therapy, but it is not clear which type is most effective. Adjuvant pelvic radiotherapy plus intracavitary radiotherapy is usually given in early-stage disease and pelvic radio therapy/or whole abdomen irradiation plus adjuvant systemic chemotherapy (PAC) in advanced disease. However, we are urgently waiting for a large prospective randomized study to compare both modalities. Paclitaxel, alone or in combination, is currently being tested in phase II studies.     

Does diagnostic hysteroscopy in patients with stage I endometrial carcinoma cause positive peritoneal washings?

OBJECTIVES: Previous studies have shown that positive peritoneal washings may adversely affect cancer survival rates and that hysteroscopy is associated with a higher risk of positive washings in patients with endometrial carcinoma. Our aim was to assess if diagnostic hysteroscopy increases the risk of positive peritoneal washings in patients with endometrial cancer and affects the prognosis after surgery. STUDY DESIGN: Retrospective cohort study. The medical records of 50 consecutive patients with endometrial carcinoma, diagnosed with hysteroscopy and tissue sampling and treated by abdominal hysterectomy with bilateral salpingo-oophorectomy and peritoneal washings were reviewed. RESULTS: Of the 43 patients with endometrial carcinoma FIGO stage I, none had positive peritoneal washings (95%CI: 0-8.2%). The mean interval between hysteroscopy and surgery was 33.5 days. The 5-year disease-specific survival rate was 91.8%, the 5-year recurrence-free survival rate was 85.4%. CONCLUSIONS: Diagnostic hysteroscopy had no adverse effect on the incidence of positive peritoneal washings or on prognosis in stage I endometrial cancer patients.     

Preoperative radiation therapy in clinical stage II endometrial carcinoma.

From 1980 to 1987, 30 patients with FIGO clinical Stage II carcinoma of the endometrium were treated with 5000 cGy preoperative pelvic radiation therapy at Thomas Jefferson University Hospital. Patients with gross cervical disease received additional intracavitary irradiation with a tandem and ovoids for a combined total dose of 7000 cGy to point A. All patients then underwent exploratory laparotomy, total abdominal hysterectomy, and bilateral salpingo-oophorectomy (TAH/BSO). The 5-year actuarial survival for the entire group was 69%. The 5-year actuarial survival for the 8 patients with papillary serous, clear cell, and undifferentiated small cell carcinoma was 38%, with most patients failing in the upper abdomen. The 5-year actuarial survival for the remaining 22 patients was 82%. The only local failure occurred in the patient with an undifferentiated small cell carcinoma. Although preoperative pelvic radiation therapy together with TAH/BSO appears to offer excellent local control in all patients with Stage II endometrial carcinoma, additional treatment options should be considered for patients with papillary serous and clear cell histologies because of the poor survival and high failure rate in the upper abdomen.     

Management of endometrial cancer with suspected cervical involvement

The 1989 International Federation of Gynecology and Obstetrics (FIGO) staging system for endometrial cancer cells for operative assessment of the extent of uterine disease, grade, and sites of metastasis before assigning a stage to the cancer. In the current study, 70 endometrial cancer patients with suspected cervical involvement based on a positive endocervical curettage or punch biopsy were treated with initial surgery followed by tailored radiation or chemotherapy. Only 37% of the patients had operative findings consistent with the preoperative suspicion of stage II disease. Postoperative therapy was determined by the extent of cervical involvement, depth of myometrial invasion, cell type, tumor grade, and the presence and location of extra-uterine disease. Based upon these parameters, 21 patients were believed to have low risk for pelvic recurrence and received no adjuvant therapy (90% 5-year survival); 38 patients received postoperative pelvic radiation because of high-risk factors for pelvic recurrence or pelvic nodal involvement (65% 5-year survival); and 11 patients received chemotherapy and/or extended radiation because of extrapelvic disease (no 5-year survivors). The approach outlined supports initial surgery for cases of endometrial cancer with suspected cervical involvement. This approach permits accurate surgical staging under the new FIGO system, avoids radiotherapy in many patients whose disease is less extensive than suspected preoperatively, and can accomplish good local control with limited morbidity.     

Clinical stage I and II endometrial carcinoma treated with surgery and/or radiation therapy: analysis of prognostic and treatment-related factors

This is an analysis of 266 patients with clinical stage I and II endometrial carcinoma treated with curative intent at the University of Florida between October 1964 and December 1980. There was a minimum 5-year follow-up. Thirty-nine patients who died of intercurrent disease less than 5 years from treatment were excluded from analysis of pelvic disease control and determinate disease-free survival. All patients were included in the analysis of complications. Pelvic disease control and determinate disease-free survival rates at 5 years were 91 and 88%, respectively, for stage I and 84 and 68% for stage II. There was no apparent difference in the rates of local control and survival or in the incidence of complications when comparing preoperative with postoperative radiation therapy. Tumor grade, stage, depth of myometrial invasion, and history of exogenous estrogen use or abnormal estrogen balance were of prognostic significance. Data on pelvic disease control, survival, and treatment complications are outlined, and management guidelines are discussed.     

Influence of grade, histologic subtype, and timing of radiotherapy on outcome among patients with stage II carcinoma of the endometrium

In 1988, the Federation of International Gynecologic Oncologists (FIGO) adopted a new staging system mandating preradiotherapy surgical staging in endometrial cancer. To evaluate the potential impact of this recommendation on patients with cervical involvement (stage II), an analysis of 184 consecutive patients with clinical or pathologic stage II carcinoma of the endometrium treated with definitive intent at three institutions was performed. Median follow-up time was 5.7 years. Treatment consisted of total abdominal hysterectomy and bilateral salpingo-oophorectomy with preoperative radiation therapy (RT) (54%), postoperative RT (37%), or both (1%); definitive RT (7%); or radical hysterectomy (1%). The median total RT dose for combined intracavitary and external beam or either alone was 70.6 Gy with a range of 32.4-105.0 Gy. The overall 5-year survival rate and disease-free survival (DFS) rate at 5 years were 70 and 79%, respectively. Of patients treated with surgery and adjuvant radiation, 13% (22/168) had infield pelvic failure (PF) and 18% (31/168) had distant metastases (DM). Patterns of failure in patients receiving preoperative and postoperative radiotherapy are presented. Univariate analysis of pretreatment and treatment factors, including histology, grade, clinical stage, extent of cervical involvement, and timing of adjuvant radiation, revealed histology and grade to be significant predictors of DFS, PF, and DM. Clinical stage was a significant predictor of DFS only in univariate analysis. Multivariate analysis found only histology (P less than 0.001) and grade (P = 0.002) to be predictors of DFS. From this review, we conclude that histology and grade are independent predictors of DFS, and more aggressive treatment should be directed at patients with stage II endometrial cancer found to have high grade adenocarcinoma or papillary serous/clear cell histologic variants. The timing of radiotherapy was not an independent predictor of outcome; therefore, preradiotherapy surgical staging should not impact on DFS and should provide surgicopathologic information to tailor treatment and predict prognosis. The FIGO clinical staging system used in this analysis was not an independent predictor of outcome, and future multivariate analyses will be necessary to test the predictive value on outcome of the new 1988 FIGO surgical staging.
