After hysterectomy, 156 evaluable patients with stage I (limited to the corpus) or stage II (limited to the corpus and cervix) uterine sarcomas were randomly assigned to adjuvant chemotherapy with Adriamycin (Adria Laboratories, Columbus, Ohio) for six months or to no further treatment. Pelvic irradiation (external or intracavitary) was optional before randomization. Of 75 patients receiving Adriamycin, 31 have suffered recurrences compared with 43 of 81 receiving no adjuvant chemotherapy. This difference is not statistically significant. Moreover, there is no difference in progression-free interval or survival. The optional radiotherapy did not influence the outcome although there was a suggestion that vaginal recurrence was decreased by pelvic radiotherapy. The recurrence rates in specific cell types (leiomyosarcoma, homologous mixed mesodermal sarcoma, or heterologous mixed mesodermal sarcoma) were not significantly different although the pattern of recurrence differed, with pulmonary metastases being more common in leiomyosarcoma and extrapulmonary recurrence being more common in mixed mesodermal sarcoma. The outcome with respect to chemotherapy was not altered even after adjusting for maldistribution of cases. Thus, we could not show a benefit for this dose schedule of Adriamycin as adjuvant treatment for uterine sarcomas.

A randomized clinical trial was conducted in women with bulky (suboptimal) Stage III and Stage IV ovarian carcinoma, using doxorubicin (Adriamycin) and cyclophosphamide with or without cisplatin. There were 440 evaluable cases, of which 227 had measurable disease. One hundred twenty of these latter patients were treated with cyclophosphamide and doxorubicin (CA), while 107 received cyclophosphamide, doxorubicin and cisplatin (CAP). The clinical complete response (CR) rate for CA was 26% (31/120) compared with 51% (55/107) for CAP (P = <0.0001). Of 23 CRs receiving CA who had a second‐look laparotomy, only four were negative; of 39 CRs receiving CAP and a second‐look, 13 were negative (not statistically significant). The response duration for patients with measurable disease (median 14.6 versus 8.8 months), progression‐free interval for all patients (13.1 versus 7.7 months), and survival for patients with measurable disease (19.7 versus 15.7 months) showed a statistically significant advantage for CAP; however, there was no difference in survival of patients with nonmeasurable disease. Toxicity was more severe with CAP but was tolerable. Thus, the addition of cisplatin improves the chemotherapy of advanced ovarian carcinoma.

Cytoplasmic progesterone and estradiol receptors in normal, hyperplastic, and carcinomatous endometria: Therapeutic implications

Clarence E. Ehrlich; Peter C.M. Young; Robert E. Cleary

This study was designed to determine whether the presence of progesterone receptors (PR) and/or estradiol receptors (ER) could be used to predict progestin responsiveness of recurrent or advanced endometrial cancers. We have demonstrated the presence of physicochemically similar cytoplasmic progesterone and estradiol receptors in normal, hyperplastic, and carcinomatous endometria. All normal endometria contained both PR and ER. Seventy-three percent of endometrial hyperplasias were PR(+) and 93% were ER(+). A decreasing concentration of progesterone receptor activity was observed with increasing tumor anaplasia [grade 1, 84% PR(+); grade 2, 55% PR(+); grade 3, 22% PR(+)] and in irradiated tumors. A statistically significant (p less than 0.001) relationship has been demonstrated between the presence of specific cytoplasmic PR and response to progestin therapy in recurrent or advanced endometrial adenocarcinomas. Thus, we conclude that a PR assay may be used to help select the most appropriate therapy for patients with recurrent or advanced endometrial adenocarcinoma.

Steroid receptors and clinical outcome in patients with adenocarcinoma of the endometrium

Clarence E. Ehrlich; Peter C.M. Young; Frederick B. Stehman; Gregory P. Sutton; William M. Alford

Progesterone receptor content was measured in tissue samples from 175 patients with endometrial adenocarcinoma by use of the dextran-charcoal method. The estradiol receptor content was determined in 138 of these samples. Ninety-two tumors (52.6%) tested positive for progesterone receptors (greater than 50 fmol/mg cytosol protein) and 111 (80.4%) tested positive for estradiol receptors (greater than 6 fmol/mg). Median follow-up was 27.3 months (range 1 to 152 months). Progesterone receptor status correlated significantly with grade, histology, adnexal spread, age, and recurrence rate in stage I cancer. There was no correlation between progesterone receptor status and clinical stage, myometrial invasion, peritoneal cytology, retroperitoneal lymph node involvement, or spread to the cervix. Estradiol receptor status correlated with adnexal spread and recurrence rate. Recurrence in patients with stage I disease was significantly more common if tumors were negative for progesterone receptor (16 of 43, 37.2%) than if they were positive (four of 57, 7%; p less than 0.001). Recurrence was also more common if tumors were negative for estradiol receptor (seven of 17, 41.2%) than if they were positive (eight of 63, 12.7%; p = 0.02). In recurrent or advanced disease, response to progestin was independent of estradiol receptor content, but tumors positive for progesterone receptors responded significantly more often than those lacking progesterone receptors. Overall survival was superior for patients with progesterone receptor-positive tumors (p = 0.001). Although survival in clinical stages I and II was also superior in patients with lesions positive for progesterone receptors (p = 0.13), there was no statistical difference in survival between patients with progesterone receptor-positive or -negative cancers and surgical stages I and II disease (p = 0.12). Estradiol receptor status had no apparent correlation with survival.

Ten-year follow-up of patients receiving cisplatin, doxorubicin, and cyclophosphamide chemotherapy for advanced epithelial ovarian carcinoma.

Gregory P. Sutton; Frederick B. Stehman; Lawrence H. Einhorn; Lawrence M. Roth; John A. Blessing; Clarence E. Ehrlich

Fifty-six patients were randomly assigned to receive either one-day cisplatin, doxorubicin, and cyclophosphamide (PAC) chemotherapy (PAC-I) or five-day PAC (PAC-V) for advanced epithelial ovarian carcinoma. Follow-up has been 120+ months or to death. Ninety-one percent had either suboptimal stage III or stage IV disease and 55% had grade 2 or 3 lesions. Two patients died of toxicity and were free of disease at autopsy. A third patient died of congestive heart failure with no disease at 103 months. Additionally, eight patients had a negative second-look laparotomy, and three (37.5%) are alive with no evidence of disease (NED) 133 to 144 months after diagnosis. Five patients (62.5%) died of disease 2 to 123 months after negative second-look. Patients with optimal stage III disease had a longer median progression-free interval (PFI) and survival (33.3 and 44.5 months, respectively) than those with suboptimal or stage IV disease (16.4 and 22.5 months, respectively), and the difference in median PFI is significant (P less than .02). Patients with ascites at diagnosis had a shorter median PFI and survival (14.7 and 18 months) than those without ascites (30.0 and 33.0 months). Both differences were significant (PFI, P less than .04; survival, P = .005). PAC produces response rates that are superior to those obtained historically with single-agent alkylating therapy. Late recurrences after negative second-look laparotomy suggest that 5-year survival data may be inadequate in ovarian carcinoma.

Extramammary pacet's disease of the vulva: A clinicopathologic study of 13 cases

Siong Chuan Lee; Lawrence M. Roth; Clarence E. Ehrlich; James A. Hall

The clinicopathologic findings of 13 patients having extramammary Pagets disease of the vulva are discussed with emphasis on its histogenesis and biological behavior. For the purpose of study and assessment of prognosis, these cases were divided into two groups, those with an underlying invasive cutaneous adnexal adenocarcinoma, and those lacking an underlying invasive lesion. Four cases contained invasive cutaneous adnexal adenocarcinoma; in one of these the invasion was superficial. Three of the cases with an invasive lesion and three other cases showed in situ adenocarcinoma of sweat glands. Surgical treatment is mandatory for both groups of patients. The prognosis was excellent for the patients having Pagets disease without an underlying invasive carcinoma. From the literature, the prognosis of those with an underlying invasive carcinoma of the vulva appears to be less favorable. Multiple surgical excisions may be required to control the recurrences and metastases. A frequent association with other internal malignancy was observed. In four cases, second malignancies were found. Of special interest was the demonstration in one case of columns of neoplastic cells extending from involved sweat glands to the surface epithelium via the intradermal sweat duct. Our study leads us to support the concept that the Pagets cells, in a number of cases, are derived from an underlying carcinoma in situ of sweat gland origin.

Malignant papillary lesions of the endometrium

Gregory P. Sutton; Lessa Brill; Frederick B. Stehman; Clarence E. Ehrlich; Helen Michael

In a review of 440 patients treated for endometrial adenocarcinoma at this center since 1974, 21 patients with tumors of papillary histology were identified. Eleven (2.5%) lesions contained histologic changes characteristic of uterine papillary serous carcinoma: complex papillary architecture, high nuclear/cytoplasmic ratio, and irregular epithelial tufting. Ten lesions (2.3%) containing areas of papillary morphology but lacking the criteria for the diagnosis of papillary serous tumors were termed papillary endometrioid adenocarcinoma. Patient age, stage, and the presence of obesity, hypertension, and diabetes were similar in both groups and reflected those characteristics well established for endometrial adenocarcinoma in general. Fewer papillary serous tumors (16.7%) and papillary endometrioid tumors (33.3%) contained progesterone receptors than did other adenocarcinomas (52.3%). In clinical stage I, surgical findings indicating a more advanced stage were present in 40% of patients with papillary serous tumors compared to 10% in papillary endometrioid tumors and 12.5% in nonpapillary adenocarcinomas (P = 0.03, Fishers exact test). Recurrences were observed in 50% of patients with papillary serous lesions compared to 42.9% in papillary endometrioid lesions and 24.3% in other adenocarcinomas. Survival for clinical stage I papillary serous tumors was worse than that for nonpapillary grade 3 controls (P = 0.042) and survival for papillary endometrioid lesions was not different from that of the same controls. These findings support those of J. L. Chen, D. C. Trost, and E. J. Wilkinson (Int. J. Gynecol. Pathol. 4, 279-288 (1985)) that papillary serous and papillary endometrioid adenocarcinomas represent two distinct subtypes of papillary endometrial neoplasia.

Progesterone binding in human endometrial carcinomas.

Peter C.M. Young; Clarence E. Ehrlich; Robert E. Cleary

Abstract By means of dextran-coated charcoal assay, the capacity of various endometrial cytosol preparations for specific binding of 3 H-progesterone was determined. With the use of an arbitrary value of 50 femtomoles of bound 3 H-progesterone per milligram of cytosol protein as the breaking point between high and low binding capacities, 19 out of 20 normal endometria had high progesterone-binding capacities. Two out of 11 Grade 1, 3 out of 8 Grade II, and 2 out of 4 Grade III endometrial carcinomas showed low binding capacities. All 4 endometrial polyps, 7 out of 9 hyperplastic endometria, and 0 out of 7 nonendometrial gynecologic tumors had high binding capacities. These data suggest a progressive loss of specific progesterone-binding activity from normal endometria to hyperplastic endometria, and from the well-differentiated to the anaplastic forms of endometrial adenocarcinoma. There seemed to be an inverse relationship between age and concentration of progesterone receptors in endometrial adenocarcinomas. All irradiated tumors studied had low progesterone-binding capacity.

Second-look laparotomy after chemotherapy in the management of ovarian malignancy

Lynda R. Smirz; Frederick B. Stehman; Thomas M. Ulbright; Gregory P. Sutton; Clarence E. Ehrlich

Eighty-eight patients with ovarian malignancy underwent second-look laparotomy as part of their plan of management at Indiana University Hospital. Thirty-five patients (39.8%) were found to have no gross or microscopic evidence of persistent neoplasm, and an additional 16 (18.2%) had only microscopic tumor. Patients with initial Stage III or IV disease were less likely to have negative findings at laparotomy than were patients with Stage I or II disease. A complete initial cytoreductive operation (residual disease = 0 cm) correlated positively with negative findings at laparotomy. Endometrioid histologic findings were associated with a favorable condition at the second look, but tumor grade was associated with superior survival only for patients with grade 0 disease. Eight of 30 patients (26.7%) with invasive carcinoma and negative findings at second-look laparotomy have had tumor recurrence (2 to 63 months), and five of eight have died. Intraperitoneal chromic phosphorus salvage therapy for patients with microscopic disease was promising, with eight of 15 treated patients (53.3%) alive after therapy, with no evidence of disease from 16 to 56 months after the second look. Second-look laparotomy has been the major determinant of continued or alternative therapy for patients with ovarian malignancy. Second-look laparotomy has been incorporated into the standard management plan without a formal clinical trial. The need for a second look may be reduced by identifying patients who do not benefit from the procedure. Patients with persistent disease confirmed by noninvasive means can continue therapy without laparotomy. There is also a subgroup of patients with a favorable prognosis whose therapy could be safely discontinued without laparotomy.

Primary carcinoma of the fallopian tube: Evidence for activity of cisplatin combination therapy☆

William Z. Maxson; Frederick B. Stehman; Thomas M. Ulbright; Gregory P. Sutton; Clarence E. Ehrlich

The records of 23 patients with confirmed carcinoma of the fallopian tube, treated between 1966 and 1983, were reviewed. Patients ranged in age from 41 to 88 years. A pelvic mass was the most common preoperative finding (61%), followed by abnormal bleeding (43%), and pain (39%). Fifteen patients had stage I or II disease, 8 had Stage III or IV disease. In patients with metastatic disease, involvement of the peritoneal surfaces, bowel, and omentum were noted most often. Lymph nodes were the most common site(s) of recurrent disease. Twelve evaluable patients with measurable disease were treated with cisplatin and cyclophosphamide (PC) +/- doxorubicin (PAC). There were 9 complete and 2 partial responses, a 92% response rate. Incorporation of cisplatin therapy appears to have resulted in improved short-term survival.
