Coordinate elevation of serum markers in ovarian cancer but not in benign disease.

Effective screening for occult ovarian cancer will require a strategy that is both sensitive and specific. Preliminary data suggest that CA 125 is elevated at diagnosis in a majority of patients with ovarian cancer. Although CA 125 is sufficiently specific to prompt its evaluation as one component of a strategy to detect ovarian cancer in postmenopausal women, a further improvement in specificity would facilitate cost-effective screening. In an attempt to develop a more specific screening strategy, multiple markers were assayed in a panel of sera from 47 patients with ovarian cancer and in a separate panel of sera from 50 individuals with benign disease whose serum CA 125 levels exceeded 35 U/ml. Among the patients with ovarian cancer, elevations of CA 125 (greater than 35 U/ml) were observed in 91%, CA 15-3 (greater than 30 U/ml) in 57%, TAG 72 (greater than 10 U/ml) in 49%, placental alkaline phosphatase (PLAP) in 25%, human milk fat globule protein (HMFG) 1 in 77%, HMFG2 in 62%, and NB/70K in 57%. Among the 50 sera selected from patients with benign disease, CA 125 was more than 35 U/ml in 100% and more than 65 U/ml in 42%. Among those patients with benign disease and elevated CA 125, NB/70K was elevated in 62%, HMFG1 in 26%, and HMFG2 in 12%, whereas TAG 72 and CA 15-3 were elevated in only 6% and 2%, respectively. In addition PLAP appeared promising; elevated enzyme levels were not found in the benign disease group. Among patients with ovarian cancer with CA 125 levels more than 35 U/ml, either TAG 72 or CA 15-3 was elevated in 77%. In the false-positive group, only 6% had elevations of one or the other marker. The CA 125 levels in cancer patients were, however, substantially greater than in patients with benign disease. If sera from patients with ovarian cancer were diluted to a range comparable to that found in benign disease, at least one of the two confirmatory tests was elevated in 63% of the samples from the malignant cases. Consequently, use of CA 15-3 and TAG 72 in combination with CA 125 can increase the apparent specificity of the CA 125 assay for distinguishing malignant from benign disease. Prospective studies will be required to test critically whether the use of additional serum markers in combination with the CA 125 assay would contribute to the specificity of a cost-effective screening strategy for ovarian cancer.

Treatment of recurrent or advanced uterine sarcoma. A randomized trial of doxorubicin versus doxorubicin and cyclophosphamide (a phase III trial of the Gynecologic Oncology Group).

Recurrent or metastatic uterine sarcoma represents an ominous and aggressive form of malignant disease. In an attempt to define a beneficial treatment program, we compared treatment with doxorubicin (A) 60 mg/m2 versus a combination of doxorubicin 60 mg/m2 and cyclophosphamide 500 mg/m (CA), each regimen given every 3 weeks. Of 132 patients entered on study, 104 were eligible; 50 received A and 54 CA. Pretreatment characteristics were similar, and no patient had received prior chemotherapy. The proportion of complete responses (CR) + partial responses (PR) for measurable disease patients was 5 of 26 (19%) for both A and CA. Multivariate analysis done on progression-free interval (PFI) and survival (S) showed CA to be of no benefit over A (PFI, P = 0.22; S, P = 0.55). For both A and CA patients, measurable disease (PFI, P = 0.002; S, P = 0.02, respectively), performance status (PFI, P = 0.004; S, P = 0.0002; respectively), and sites of residual disease (PFI, P = 0.008; S, P = 0.003, respectively) were detected as prognostic variables. Conversely, histologic type, age, and recurrence status (primary versus recurrent at entry) were not prognostic indicators. These data indicate no significant benefit of CA versus A alone in patients with uterine sarcoma.

Survival and patterns of recurrence in cervical cancer metastatic to periaortic lymph nodes (a Gynecologic Oncology Group study).

Ninety-eight of 621 evaluable patients (16%) with cervical cancer enrolled into Gynecologic Oncology Group protocols were found to have periaortic lymph node metastases at staging laparotomy or at exploration for definitive operative management. As expected there was a progressive increase in the prevalence of periaortic metastases including 5% of 150 patients with Stage IB, 16% of 222 patients with Stage II, and 25% of 135 patients with Stage III. Periaortic lymph node metastases in the absence of pelvic lymph node metastases was an infrequent occurrence in patients so evaluated. The median survival of patients with periaortic metastases was 15.2 months with a survival probability of 25% at 3 years. The median duration of survival following recurrence was only 5 months. Recurrences were divided approximately equally between the pelvis and distant sites.

A comparison of medroxyprogesterone serum concentrations by the oral or intramuscular route in patients with persistent or recurrent endometrial carcinoma.

A randomized study, comparing serum medroxyprogesterone concentrations by the oral and intramuscular routes, was performed on 22 patients with persistent or recurrent endometrial adenocarcinoma by six institutions of the Gynecologic Oncology Group. The oral group (11 patients) received cutaneous Provera (medroxyprogesterone), 50 mg three times a day, and the intramuscular group (11 patients) received 300 mg of Depo-Provera (medroxyprogesterone) weekly for at least 2 months. Serum levels were evaluated at 0, 2, 4, 6, 8, 10, and 12 hours after administration and every day for the first week and weekly thereafter for 8 weeks. The mean serum levels (nanograms per milliliter) of medroxyprogesterone in the oral group were consistently higher than the corresponding mean levels of the intramuscular group. In addition, from the first through eighth weeks, the measurements (medians) for the oral group were statistically higher than those for the intramuscular group. Although the study indicates a significant increase in serum levels achieved by the oral route, the follow-up period of patients under study is too early to evaluate its clinical effectiveness as compared to the intramuscular route.

Toxicity manifestations following intravenous Corynebacterium parvum administration to patients with ovarian and cervical carcinoma.

Manifestations of clinical toxicity were evaluated following 341 courses of intravenous Corynebacterium parvum adjuvant immunotherapy in patients with ovarian and cervical carcinoma. Most patients exhibited symptoms of minor toxicity, which decreased in intensity as subsequent courses of therapy were administered. Temperature elevations to 38.5 degrees C. were the most objectively measured signs of toxicity but temperature elevations greater than 38.5 degrees C. occurred following only 20.5 per cent of the infusions. Blood pressure alterations were not a serious problem and no serious central nervous system or renal toxicity was noted. The minor side effects should not preclude the use of C. parvum as an immunopotentiating agent if it is shown to be beneficial in the treatment of human malignant disease.

Operative management of early invasive epidermoid carcinoma of the vulva.

The clinical records and surgical specimens of 60 patients with squamous cancers of the vulva less than 2 cm in size (TI) were studied. Fifty-eight patients had stromal invasion 5 mm. or less in depth. Three of the 60 patients (5 per cent) had pelvic lymph node metastases; two of these three showed invasion of vascular channels; the third patient's tumor showed cellular anaplasia. In an effort to reduce patient morbidity in radical surgery for vulvar carcinoma, while achieving comparable survival data, an operative approach less radical than radical vulvectomy, inguinal dissections, and/or pelvic lymphadenectomy is proposed for selected patients.
