Stage II carcinoma of the endometrium: results of therapy and prognostic factors.

A retrospective analysis is reported of 116 patients with Stage II carcinoma of the endometrium treated definitively with combined radiation and total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) or irradiation alone from January 1960 through December 1981. At 5 and 10 years, the overall survival for all patients was 71 and 52% and the disease-free survival was 73 and 69%, respectively. Of 90 patients in the combined therapy group, most received a preoperative intracavitary insertion (3500 mgh to the uterus and 2000 mgh to the upper vagina) and preoperative external beam pelvic irradiation (2000 cGy whole pelvis, additional 3000 cGy to parametria, with midline shield) followed in 4 to 6 weeks by a TAH-BSO. The 5 and 10 year disease-free survival for this group was 78 and 75%, respectively. The incidence of major complications was 7% for the combined therapy group. Twenty-six patients were treated with irradiation alone; most of them received two intracavitary insertions (5000 mgh to the uterus and 3000 mgh to the upper vagina) and external beam pelvic irradiation (2000 cGy whole pelvis, additional 3000 cGy to parametria). The 5 and 10 year disease-free survival was 53 and 45%, respectively. The incidence of major complications was 19%. Factors found to influence the prognosis were histologic grade of tumor, clinical and histologic degree of tumor involvement of the ectocervix, presence of residual tumor in the hysterectomy specimen and the depth of myometrial invasion.

Clinical stage I endometrial cancer: results of adjuvant irradiation and patterns of failure.

A retrospective analysis is reported in 858 patients with clinical Stage I carcinoma of the endometrium treated definitively from January 1960 through December 1986 with combined irradiation and total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO). Most patients received a preoperative intracavitary insertion (2500-4000 mgh to the uterus with Heyman capsules and tandem and 6500 cGy surface dose to the upper vagina) followed by a TAH-BSO within 6 weeks. Some patients received postoperative external beam irradiation (2000 cGy whole pelvis and an additional 3000 cGy to the parametria, with a midline stepwedge) when deep myometrial invasion was present. Occasionally patients were treated with preoperative external beam irradiation (2000 cGy whole pelvis) and intracavitary insertion. The 5-year overall survival for all patients was 84.0% compared to an expected survival of 88.8%. The 5-year progression-free survivals were 92% for FIGO clinical Stage IA and 86% for stage IB (p = 0.12). The dose to the uterine fundus from the preoperative intracavitary insertion was found to have a significant correlation with progression-free survival in patients with grade 3 tumors. Those receiving less than 2500 mgh to the uterine cavity had a 48.9% 5-year progression-free survival compared to 62.7% for 2500-3500 mgh and 87.4% for those receiving greater than 3500 mgh. Analysis of sites of failure showed that less than 1% (7/858) failed in the pelvis alone, 3% (30/858) in the pelvis combined with distant sites, and 7% (60/858) developed distant metastasis only. The lateral pelvic sidewall was the most common site of failure within the pelvis (20/37) and intraperitoneal failures (28/90) and lung (21/90) were the most common sites of distant metastasis. The overall severe (grades 2, 3, and 4) complication rate was 2.7% (23/858).

Brachytherapy-related complications for medically inoperable stage I endometrial carcinoma.

PURPOSE: The current study was conducted to investigate the incidence and risk factors for medical complications associated with low dose rate brachytherapy in patients with medically inoperable Stage I endometrial cancer treated with irradiation alone. METHODS AND MATERIALS: From 1965 through 1991 at Mallinckrodt Institute of Radiology, 150 implants were performed on 96 patients who were deemed medically unfit for hysterectomy because of advanced age, obesity, and various medical problems. The records of these patients were examined retrospectively to determine the incidence of medical complications that occurred in the first 30 days following the initiation of brachytherapy. The association of risk factors that precluded major surgery and the occurrence of brachytherapy-related complications was examined by logistic regression. RESULTS: Of these 96 patients, 40 patients were older than 75 years, and 31 patients were deemed morbidly obese. Medical problems included hypertension in 45 patients, and diabetes in 37; there was a history of congestive heart failure in 23, stroke in 11, myocardial infarction in 10, and thromboembolism in 8. There were concurrent malignancies in five patients. Implants were performed using intrauterine Simon-Heyman capsules, tandems, and vaginal ovoids in all patients. General anesthesia was used for 98 implants, spinal anesthesia for 26, local anesthesia for 25, and epidural anesthesia for 1. The duration of anesthesia ranged from 30 to 120 min (median, 60 min). The duration of radioisotope application ranged from 11 to 96 h (median, 46 h). Preventive measures included low dose subcutaneous heparin in 55 patients (since 1978), and intermittent pneumatic compression boots in 29 (since 1985). Four patients developed life-threatening complications including myocardial infarction (two patients), congestive heart failure (one patient), and pulmonary embolism (one patient). Two of these four patients died; one with a myocardial infarction and the other with pulmonary embolism. The morbidity rate was thus 4.2% (4 out of 96), and the mortality was 2.1% (2 out of 96). Although the four serious complications occurred within 30 days of the procedure, only one complication and one death occurred during treatment. There was no correlation between occurrence of complications and medical risk factors, type and duration of anesthesia, or type and duration of implant. CONCLUSIONS: There is a low incidence of complications associated with conventional low dose rate brachytherapy. The procedure is well tolerated in patients with medically inoperable Stage I endometrial cancer. In comparison to the predicted serious complication rate of surgery in these patients, the number of life-threatening complications from brachytherapy appears to be quite acceptable.

Irradiation alone or combined with surgery in stage IB, IIA, and IIB carcinoma of uterine cervix: update of a nonrandomized comparison.

PURPOSE: Definitive radiation therapy alone or combined with surgery in carcinoma of the uterine cervix yields comparable tumor control and survival in Stages I and IIA when patients are adequately treated with either modality. Our 30-year institutional experience is described. METHODS AND MATERIALS: This is a nonrandomized comparison of treatment results of 415 patients with Stage IB, 137 with Stage IIA, and 340 with Stage IIB carcinoma of the uterine cervix treated with irradiation alone and 197 with Stage IB, 44 with Stage IIA, and 65 with limited Stage IIB treated with pre- or postoperative irradiation and surgery. Irradiation alone consisted of a combination of external beam therapy and intracavitary insertions to deliver doses of 70 to 85 Gy to point A for patients with Stages IB and IIA disease and 80 to 90 Gy for patients with bulky or Stage IIB tumors. For patients treated with irradiation and surgery, various combinations of external beam and intracavitary therapy were used to deliver 60 to 75 Gy to point A. Surgical procedures consisted of radical hysterectomy with or without lymph node dissection in 130 patients with Stage IB, 28 patients with Stage IIA, and 10 patients with limited Stage IIB. Fifty-seven patients had total abdominal or conservative hysterectomy with or without lymph node dissection, and 3 had vaginal hysterectomy. In addition, 51 patients with Stage IIB tumors underwent pelvic lymphadenectomy after definitive irradiation. RESULTS: The 5-year cause-specific survival (CSS) rates for patients with Stage IB nonbulky tumors treated with irradiation alone or irradiation combined with surgery were 90 and 85%, respectively, and the 10-year survival rate was 84% with either modality. In patients with bulky tumors (> 5 cm), the 5-year CSS rates were 61% with irradiation alone and 63% with irradiation plus surgery; at 10 years the rates were 61 and 68%, respectively (p = 0.5). For those with Stage IIA nonbulky tumors, the 5-year CSS rates were 75% with irradiation alone and 83% with combined irradiation and surgery, and 10-year CSS rates were 66 and 71%, respectively. In patients with Stage IIA bulky tumors, the 5-year CSS rates were 69% with irradiation alone and 60% with irradiation plus surgery, and at 10 years, 69 and 44%, respectively (p = 0.05). In patients with Stage IIB nonbulky tumors treated with irradiation alone or combined with surgery, the 5- and 10-year CCS rates were 72 and 65%, respectively; the corresponding survival rates with bulky tumors or bilateral parametrial involvement were 56 and 50%. Incidence of pelvic failures, alone or with distant metastasis, for Stage IB was 10% (43 out of 415) with irradiation alone and 14% (28 of 197) with irradiation plus surgery; for Stage IIA, 17% (23 out of 137) with irradiation alone and 20% (9 our of 44) with irradiation plus surgery; and for Stage IIB, 23% (88 out of 391) with irradiation alone and 29% (4 out of 14) with irradiation plus surgery. Grade 3 sequelae were comparable in both groups (irradiation alone, 5% to 11%; irradiation combined with surgery, 8% to 12%); the differences are not statistically significant. The most frequent major sequelae in 892 patients receiving irradiation only were rectovaginal fistula (13 cases, 1.5%), proctitis (10, 1.1%), small bowel obstruction (16, 1.8%), ureteral stricture (16, 1.8%), and vesicovaginal fistula (8, 0.9%). In 306 patients treated with irradiation plus surgery, the most commonly recorded major sequelae were small bowel obstruction/perforation (13 cases, 4.2%), ureteral stricture (8, 2.6%), vesicovaginal fistula (5, 1.6%), and rectovaginal fistula (4, 1.3%). CONCLUSION: Irradiation alone or combined with surgery yields comparable pelvic tumor control, survival, and morbidity in patients with Stage IB, IIA, and limited IIB carcinoma of the uterine cervix.

Definitive irradiation in carcinoma of the vagina: long-term evaluation of results.

A retrospective analysis of 165 patients with histologically confirmed carcinoma of the vagina is reported. Actuarial disease-free 10-year survival was: Stage 0 (16 patients)--94%, Stage I (50 patients)--75%, Stage IIA (49 patients)--55%, Stage IIB (26 patients)--43%, Stage III (16 patients)--32%, Stage IV (8 patients)--0%. All but one of the in situ lesions were controlled with intracavitary therapy. Of the patients with Stage I disease, 86% showed no evidence of vaginal or pelvic recurrence. Most of them received interstitial or intracavitary therapy or both; the addition of external beam irradiation did not significantly increase survival or tumor control. In Stage IIA (paravaginal extension) 61% of the tumors were controlled with a combination of brachytherapy and external beam irradiation. Ten of 16 Stage III tumors were controlled in the pelvis. Two of the patients with Stage IV disease had no recurrence in the pelvis with relatively high doses of irradiation. The total incidence of distant metastases was 16% in Stage I, 30.6% in Stage IIA, 46.1% in Stage IIB, 62% in Stage III, and 50% in Stage IV. The dose of irradiation delivered to the primary tumor or the parametrial extension was critical in achieving successful results. The incidence of grade 2-3 complications (12%) is correlated with the stage of the tumor and type of treatment given. More effective irradiation techniques including the optimization of dose distribution by judicious combination of external irradiation and interstitial brachytherapy will be necessary to enhance loco-regional tumor control. The high incidence of distant metastases underscores the need for earlier diagnosis and effective systemic cytotoxic agents if survival is to be significantly improved in these patients.

Analysis of pelvic tumor control and impact on survival in carcinoma of the uterine cervix treated with radiation therapy alone.

A total of 1054 patients with histologically confirmed invasive carcinoma of the uterine cervix were treated with radiation therapy alone between 1959 and 1982. All patients are available for a minimum of 3 years follow-up. Radiation therapy consisted of external irradiation to the whole pelvis (1000-2000 cGy) and parametria (for a total of 4000-6000 cGy) combined with two intracavitary radioactive source insertions (6000-7500 cGy to point A). Patients with Stage IIB, III, and IVA have been consistently treated with somewhat higher doses of external irradiation and intracavitary insertions. A small group of 54 patients with Stage IIB or IIIB had pelvic lymphadenectomy following the irradiation (1960-1964). There was a strong correlation between the tumor regression within 30 days from completion of radiotherapy and the incidence of pelvic recurrences or distant metastases for each of the anatomical stages. The 10-year survival rate for Stage IB was 76%, Stage IIA 60%, Stage IIB 45%, and Stage III 25%. Many of the deaths were due to intercurrent disease. Thus, the 10-year tumor-free survival was 80% for Stage IB, 60% for Stages IIA and IIB and 35% for Stage III. In Stage IB total doses of 6000 cGy or higher to point A resulted in 94% pelvic tumor control. In Stage IIA, the pelvic tumor control was 87% with doses of 6000 cGy to point A or higher. However, in Stage IIB the pelvic tumor control was 58% with doses below 6000 cGy, 78% with 6001-7500 cGy and 82% with higher doses. In Stage IIIB the pelvic tumor control was 42% with doses below 6000 cGy, 57% with 6001-7500 cGy and 68% with higher doses. Tumor control in the pelvis was correlated with the following 5 year survivals: Stage IB-95% (353 patients); Stage IIA-84% (116 patients); Stage IIB-84% (308 patients); Stage IIIB-74% (245 patients). The 5-year survival for patients that recurred in the pelvis was 30% for Stage IB, about 15% for Stages IIA-B and only 5% in Stage III. Patients with tumor control in the pelvis had a significantly lower incidence of distant metastases than patients who initially failed in the pelvis (9.3% vs. 58.6% in Stage IB, 21.6% vs 52.6% in Stage IIA, 19.8% vs 16.7% in Stage IIB, and 31.2% vs 50% in Stage III). In Stage IIB the figures were 19.8% and 16.7% because the initial pelvic recurrence was frequently concurrent with distant metastases.(ABSTRACT TRUNCATED AT 400 WORDS)

Radiation therapy and conservation surgery for primary and recurrent carcinoma of the vulva: report of 40 patients and a review of the literature.

Forty patients with histologically confirmed primary or recurrent vulvar carcinoma were treated with radiation therapy for loco-regional disease. Nineteen of the patients with primary tumors received postoperative radiotherapy (5000 cGy in 6 weeks). Fifteen of the 19 exhibited local tumor control. Five patients with Stage III or IV disease were managed with radiotherapy alone. Four had a complete response with two currently NED. Two patients who received preoperative radiotherapy with local excision are also currently free of disease. The 4-year NED survival for the study population is 100%, 28%, 50%, 0% and 10% for Stage I, II, III, IV and recurrent tumors respectively. The poor results obtained in Stage II tumors is likely due to selection criteria since four of seven patients developed distant metastases. Two of the 14 patients treated for recurrent disease remain NED after local excision of their tumors prior to irradiation. Even though the number of patients is small no dose response for subclinical disease could be found between 4500 and 7000 cGy. Treatment morbidity was acceptable with two patients developing severe long-term complications requiring surgical intervention.

Clinical stage I endometrial cancer: prognostic factors for local control and distant metastasis and implications of the new FIGO surgical staging system.

A retrospective analysis is reported in 858 patients with clinical Stage I carcinoma of the endometrium treated definitively with combined irradiation and total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) from January 1960 through December 1986. Most patients received a preoperative intracavitary insertion (3500-4000 mgh to the uterus and a 6500 cGy surface dose to the upper vagina) followed by a TAH-BSO within 1-2 weeks. Some patients received postoperative external beam irradiation (2000 cGy whole pelvis and an additional 3000 cGy to the parametria, with a midline stepwedge) when factors such as deep myometrial invasion were present. Occasionally patients were treated with a preoperative intracavitary insertion and preoperative external beam irradiation (2000 cGy whole pelvis). The 5-year progression-free survivals by FIGO (1988) surgical stage were 93% for IA, 90% for IB, and 91% for Stage IC. An analysis of multiple variables was performed to ascertain their prognostic significance. Factors that significantly affected the 5-year progression-free survivals by univariate analysis were grade (grade 1 = 95%, grade 2 = 88%, grade 3 = 73%; p less than 0.0001), histology (adenoacanthoma = 96%, clear cell = 89%, adenocarcinoma = 89%, papillary = 81%, adenosquamous = 80%; p = 0.04), lower uterine segment involvement (uninvolved = 89%, involved = 73%; p = 0.006), depth of myometrial invasion (no residual tumor = 91%, limited to the endometrium = 96%, less than 1/3 myometrial penetration = 92%, 1/3 - 2/3 = 100%, greater than 2/3 = 50%; p = 0.02), peritoneal cytology (negative = 92%, positive = 56%, p less than 0.0001), uterine serosal involvement (uninvolved = 89%, involved = 55%; p less than 0.0001), vascular space invasion (absent = 89%, present = 75%; p = 0.001), and the presence of extrauterine disease (absent = 90%, present = 64%; p less than 0.0001). A multivariate analysis of these prognostic variables showed that histological grade (p = 0.001), peritoneal cytology (p = 0.004), and uterine serosal involvement were prognostic for local failure and that peritoneal cytology (p less than 0.001), grade (p = 0.001), age (p = 0.002), and extrauterine disease (p = 0.02) were prognostic for the development of distant metastasis.

Adenocarcinoma of the uterine cervix: lack of evidence for a poor prognosis.

A retrospective analysis was performed to evaluate the prognostic significance of histologic type (epidermoid carcinoma versus adenocarcinoma) on local control of disease and on the development of distant metastatic disease in 1239 patients with carcinoma of the uterine cervix treated with radiation therapy alone or surgery and irradiation at the Radiation Oncology Center, Mallinckrodt Institute of Radiology (MIR), Washington University Medical Center, between 1959 and 1982. The 5-year disease-free survival (all stages combined) was 68.0% for 925 patients with epidermoid carcinoma compared to 64.9% for 79 patients with adenocarcinoma treated with irradiation alone (p = 0.34). There was no significant difference in the survival rate when epidermoid carcinoma and adenocarcinoma were compared after stratification by clinical stage except for stage III. The 5-year disease-free survival (all stages combined) was 73.4% for 213 patients with epidermoid carcinoma and 77.0% for 22 patients with adenocarcinoma treated with irradiation plus surgery (p= 0.74). Prognostic variables analyzed by multivariate analysis included age at diagnosis, histology, size of lesion, endometrial extension, lymph node status (as evaluated by lymphangiogram), dose to point A, and surgery. Prognostic variables that were significant (p less than 0.05) for the development of recurrent disease in the pelvis were size of the primary lesion and dose of irradiation to point A. Significant (p less than 0.05) factors for the development of distant metastatic disease were size of the primary lesion and metastatic lymph nodes at the time of diagnosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Prospective phase I/II studies of definitive irradiation and chemotherapy for advanced gynecologic malignancies.

PURPOSE: This is a prospective study to evaluate toxicity and efficacy of concurrent irradiation and three cycles of chemotherapy bolus cisplatin and infusion 5-fluorouracil (5FU) in patients with advanced gynecologic malignancies. MATERIALS AND METHODS: Patients received cisplatin, 50 mg/m2 I.V. rapid infusion, and 5-day continuous infusion of 5FU (750 mg/m2 per day (schedule A); or cisplatin 75 mg/m2 i.v. rapid infusion, and 4-day continuous infusion of 5FU 1,000 mg/m2 per day (schedule B). Schedule A was given to 25 patients in the first 36 months of the study and was changed to schedule B in an additional 42 patients. All patients received irradiation, which usually consisted of 20 Gy whole pelvis, 30-40 Gy split field, and two intracavitary insertions for a total of 80-90 Gy to point A. Primary cervical cancer occurred in 40 patients with 3 having stage IB bulky, 2 with stage IIA, 5 with stage IIB, 2 with stage IIIA, 23 with stage IIIB, 4 with stage IV, and 1 with stage IVB. Recurrent cervical carcinoma after radical hysterectomy occurred in 18 patients. The remainder of the patients consisted of two each with stages III and IV endometrial carcinoma, two with stage III vaginal carcinoma, two with stage III vulvar carcinoma, and one with recurrent vulvar carcinoma. Patients were treated from 1985 through 1992. RESULTS: The 5-year overall survivals for patients with stages IB (bulky)-IIB cervical cancer was 70%, 25% for stages IIIA-IVA, and 39% for patients with recurrent cervical carcinoma. All four patients with endometrial carcinoma have recurred and died. Two patients with vulvar carcinoma are alive and free of disease, and one is dead of intercurrent disease. One patient with stage III vaginal carcinoma is alive and free of disease, while the other recurred and died. No significant differences were observed in the toxicity of the two chemotherapy schedules. There were 9/39 (23%) grade 4 and one fatal complication in those with primary cervical carcinoma. The overall fistulae rate was 11% (4/39) with three patients developing rectovaginal fistulae and one having vesicovaginal fistula. CONCLUSION: Concurrent chemotherapy and irradiation for advanced gynecologic malignancies as administered in this study is highly toxic and fails to demonstrate an obvious survival improvement.

Treatment of carcinoma of the fallopian tube using cisplatin, doxorubicin, and cyclophosphamide.

Nine patients with metastatic carcinoma of the fallopian tube were treated with a combination of cisplatin, doxorubicin, and cyclophosphamide. Three are in complete clinical remission following surgically documented complete response, at 18-56 months following the onset of chemotherapy. Two others died of intercurrent causes without evidence of disease. The remaining four died of tumor at 12, 23, 28, and 52 months following the initiation of treatment. Four second-look laparotomies were performed upon patients who were in complete clinical remission. No disease was found in any of these patients. It is concluded that this combination is an effective treatment for adenocarcinoma of the fallopian tube, and that second-look laparotomy may be useful in assessing response to chemotherapy in this disease.

Phase I/II study of definitive radiotherapy and chemotherapy (cisplatin and 5-fluorouracil) for advanced or recurrent gynecologic malignancies. Preliminary report.

Twenty-three patients with advanced gynecologic malignancy were treated with definitive irradiation and synchronous sensitizing chemotherapy (CT) consisting of cisplatin (CDDP), 50 mg/m2 i.v. rapid infusion, and a 5-day continuous infusion of 5-fluorouracil (5-FU), 750 mg/m2/day. A total of three cycles were administered every 3-4 weeks. Fifteen patients had primary cervical epidermoid carcinoma (three bulky stage IIB, one stage IIIA, ten stage IIIB, one stage IV), four had pelvic recurrences of carcinoma of the cervix, two had endometrial adenocarcinomas (stage IV), and two had vulvar epidermoid carcinoma (one stage III and one stage IV). Radiotherapy (RT) for implantable tumors consisted of 2,000 cGy whole pelvis, 3,000-4,000 cGy split field, and two intracavitary or interstitial insertions, resulting in a total dose of 7,500-8,000 cGy to point A. Three courses of CT were delivered simultaneously with irradiation of the central bulk of tumor: during the first week of whole pelvis RT and with each of the two brachytherapy procedures. Nonimplantable tumors were treated with protracted external beam RT (5,500 cGy tumor dose) and three courses of CT during weeks 1, 4, and 7 of RT. Twenty-one of 23 patients completed RT and 18 of 23 patients completed CT as planned, but half had delays in either RT or CT. Grade 2 or 3 late sequelae consisted of leg edema (one patient), proctosigmoiditis (one patient), bowel obstruction (one patient), vesicovaginal fistula (one patient), and pulmonary embolus (two--one fatal). The incidence of grade 2 and 3 sequelae were 18 and 22%, respectively. With 1-3 years of follow-up evaluation, 12 of 23 (52%) patients are free of disease, and 9 of 22 evaluable patients (41%) have had failure within the pelvis. We conclude that high-dose definitive RT can be delivered with synchronous CDDP and 5-FU at the doses given, with acceptable toxicity. Further study is required to evaluate the impact of radiosensitization on tumor control and late morbidity of therapy. Optimization of irradiation and drug doses as well as the best schedules that may enhance the interaction of these two modalities should be further investigated.

Adenocarcinoma of the uterine cervix.

From January 1, 1947, through December 31, 1971, 219 patients with primary adenocarcinoma of the intact uterine cervix were treated at the M.D. Anderson Hospital and Tumor Institute. Two modes of therapy were primarily used, namely, irradiationtherapy alone and irradiation therapy plus operation. The 5 year survival resultsare 83.7 per cent for patients with Stage i disease, 48.0 per cent for patients with Stage ii disease, 29.2 per cent for patients with Stage iii disease, and 0.0 per cent for patients with Stage iv disease. The group with irradiation plus operation had a better over-all survival rate. In addition, the incidence of central and pelvic recurrent disease was remarkably lower (fourfold difference). The urologic and bowel complications are discussed. This review lends support for our practice of preoperative irradiation followed by simple (constructive) hysterectomy for selected patients eith adenocarcinoma of the uterine cervix.

Results of therapy, analysis of failures, and prognostic factors for clinical and pathologic stage III adenocarcinoma of the endometrium.

A retrospective analysis was performed on 427 patients with clinical stage I, II, and III adenocarcinoma of the endometrium treated definitively with total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) and pre- or postoperative irradiation at our institution from January 1960 through December 1981. Of 310 patients with clinical stage I, 21 (6.8%) and 9 of 90 (10%) clinical stage II patients were found to have pathologic stage III (CS I-II/PS III) tumors. In addition, 27 patients had clinical stage III (CS III) tumors at the time of diagnosis. At 5 years the overall and disease-free survival for all patients with clinical and/or pathologic stage III disease was 43.5 and 46.2%, respectively. The 5-year disease-free survival for CS I/PS III was 67.3% compared to 32.6% for CS II/PS III and 33.4% for CS III. Failure to control the disease in the pelvis occurred in 14.3% of the CS I/PS III patients and in 44.4 and 33.3% of the CS II/PS III and CS III patients, respectively. The appearance of distant metastasis was higher with increasing stage (19.1% for CS I/PS III, 33.3% for CS II/PS III, and 48.1% for CS III). Eighty percent of all failures occurred within 40 months. Grade of the tumor was associated with increasing pathologic stage but not with ability to control the disease in the pelvis. However, there was a tendency for higher grade lesions to fail more often at distant sites.

Serum copper in ovarian carcinoma.

The serum copper and CA 125 levels of 31 patients with epithelial ovarian carcinoma were determined. Serum copper was elevated in seven patients and CA 125 was elevated in 22 patients. A rise in serum CA 125 always was associated with disease progression. In comparison, serum copper fluctuation did not correlate with the natural history of the malignancy. We concluded that serum copper determination has no use in epithelial ovarian carcinoma management.

Outcome of recurrent cervical carcinoma following definitive irradiation.

This report is a retrospective analysis of 376 patients with recurrent cervical carcinoma, following definitive radiation therapy to 1054 patients with stage IB-IVA carcinoma of the uterine cervix treated at the Radiation Oncology Center, Mallinckrodt Institute of Radiology, from January 1959 through December 1982. The sites of failure after treatment by stage at initial diagnosis were classified as pelvic only (P), pelvic plus distant metastasis (P + DM), or distant metastasis only (DM). The sites of first failure were for stage IB, P = 0.8%, P + DM = 7.4%, DM = 7.9%; for stage IIA, P = 1.7%, P + DM = 14.7%, DM = 17.2%; for stage IIB, P = 10.4%, P + DM = 11.0%, DM = 14.9%; for stage III, P = 15.4%, P + DM = 23.9%, DM = 18.9%; and for stage IV, P = 16.7%, P + DM = 61.1%, DM = 16.7%. The actuarial probability of pelvic failure at 5 years from initial therapy was 8% for stage IB, 16% for stage IIA, 21% for stage IIB, 42% for stage III, and 100% for stage IV. The incidence of distant metastasis at 5 years was 14, 32, 28, 47, and 100% for stages IB, IIA, IIB, III, and IV, respectively. The therapy after failure was surgery, irradiation, irradiation plus surgery, or chemotherapy. There appeared to be no major difference in survival after recurrence by type of treatment or initial stage. The overall survival at 5 years for all untreated patients was 1%. The median survival was evaluated as a function of time to failure after initial treatment. Patients who developed disease more than 36 months after initial treatment had a median survival of 22.5 months. The median survival was 12.1, 7.6, 9.4, and 9.1 months for those failing less than 6, 6-12, 13-24, and 25-36 months after initial treatment. Severe treatment complications occurred in 3.6% (5/140).

Therapy of ovarian carcinoma: the relationship of dose level and treatment intensity to survival.

Following primary maximal cytoreduction, 71 previously untreated patients with advanced epithelial ovarian carcinoma received at least six courses of combination chemotherapy consisting of cisplatin, doxorubicin, and cyclophosphamide. The cumulative dose (CD) through three (CD3) and six (CD6) courses was calculated for each drug and for all drugs combined. The dose intensity (DI) through three (DI3) and six (DI6) courses was calculated for each drug by dividing CD3 and CD6 by the interval (in weeks) between surgery and the third and sixth course. The interval from surgery to the third or sixth course had no effect on survival. Similarly, there was no significant difference in survival between patients with high and low CD3 or CD6 for any drug or for all drugs combined. Patients with high DI6 for cisplatin, doxorubicin, and all drugs combined survived significantly longer than those with low DI6. The survival difference for patients with high and low DI6 for cyclophosphamide approached, but did not attain, statistical significance at the 0.05 level. The intensity with which combination chemotherapy is administered may have an impact upon survival in patients with ovarian carcinoma.
