A 46-year-old nulligravida complained of the recent development of an erythematous skin eruption and fine blond hair over her face. These complaints appeared to be symptoms of acquired hypertrichosis lanuginosa, which may be associated with malignancy. The patient was found to have an endometrial adenocarcinoma with nodal metastases and was treated with hysterectomy and irradiation. Eighteen months later there was no evidence of the cancer, and the lanugo hairs had vanished. This is the first known instance of hypertrichosis lanuginosa associated with a gynecologic cancer and the first ever observed in which the lanugo hairs disappeared after cancer therapy.

Computed tomography-guided fine-needle aspiration was performed on 30 retroperitoneal lymph nodes in 29 patients with gynecologic cancer. There were no serious complications. Review of the cytologic material demonstrated malignant cells in 83% of the aspirates. Because the predictive value of a positive aspirate approaches 100%, therapy for metastatic disease can be initiated in these patients with the need for an open biopsy. Among five aspirates in which malignant cells were not seen, the cellularity of the specimen appeared to be the critical factor determining the predictive value of the aspirate. Whereas neither of two patients with negative aspirates of adequate cellularity has developed recurrent disease, two of three patients with hypocellular negative aspirates have. Because a hypocellular negative aspirate from a retroperitoneal lymph node may not be a true reflection of disease status, either repeat aspiration or open biopsy is advisable.

Transcatheter internal iliac arterial embolization therapy (TAE) using Gelfoam particles was performed in 24 patients with recurrent gynecologic cancer and ten patients with advanced gynecologic cancer who had previously undergone radiotherapy. The tumor showed complete response (CR) to the therapy in six patients, partial response (PR) in 12, minor response (MR) in three, and no changes (NC) in 13 patients, with the response rate (CR + PR) of 52.9% (18 of 34). No serious or prolonged side effects were encountered except for vesicovaginal fistula in three patients and renal failure in one. The median duration of survival was 299 days, and the 1-year cumulative survival rate was 32.5%. The factors that were associated with favorable outcome after TAE were good general condition, no distant metastases, tumors less than 5 cm in diameter, and responses to the therapy of PR or better. Thus, TAE appears useful for the treatment of recurrent and advanced gynecologic malignancies.

Seven cases of patients with gynecologic cancer and Sister Joseph's nodule, umbilical metastases from intraabdominal malignancy, are presented, making a total of 44 such cases in the literature. One such case, uterine leiomyosarcoma with umbilical metastases, is the first such lesion reported. Although the prognosis is generally poor, a few long-term survivors have been reported, and aggressive therapy may be warranted, particularly in patients with ovarian malignancy.

Placental-type alkaline phosphatase was measured in sera, cyst, and ascites fluids, and from tumor extracts obtained from gynecologic cancer patients, particularly those with cancer of the ovary. A modified assay was used that depended on long incubation (20 to 24 hours) to measure the heat-stable, phenylalanine-sensitive placental isoenzyme. The concentration of enzyme in ascites and cyst fluids was markedly higher than in serum. Cyst fluid values were generally higher than ascites fluids from the same individual. The median enzyme levels for malignant cyst fluids were 50 times greater than for benign cyst fluids. When tumor tissue and fluids were available from the same patients, it was observed that the levels in each were proportional. Determination of this isoenzyme in serum did not give a useful index of tumor burden, as metastatic disease did not consistently result in elevated serum enzyme levels. When ovarian cancer patients were divided into two groups--those in whose sera placental-type phosphatase was elevated, and those in whom it was not--the presence of the enzyme in serum at the time of tumor diagnosis appeared to be a negative prognostic indicator, judged from survival data.

Lymphatic metastasis is one of the most important problems in the treatment of gynecologic malignancy. We conducted a preliminary investigation on the feasibility and practicality of chemotherapy against lymphatic metastases of gynecologic cancer via pelvic retroperitoneal cannulation. 5-FU mixed with Isovist-300 was injected into the pelvic retroperitoneal space. X-ray films revealed that the external iliac, hypogastric, obturator, deep inguinal and most of the common iliac lymph nodes were submerged in the 5-FU solution. 5-FU concentrations in the lymph nodes were measured by high pressure liquid chromatography, which showed that 5-FU concentration of the study group was 2 to 10 times that of the control group. Pathologic findings revealed that most of the metastatic cancer cells in the study group showed obvious degeneration and necrosis while no changes were observed in the control group. No major complications or adverse effects were observed. Our results suggest that this method may be used to treat the lymphatic metastases of gynecologic cancer.

Pelvic and paraaortal lymph nodes of 499 gynecologic cancer patients were screened for the occurrence of metaplastic changes and their topographic pattern. Glandular inclusions in lymph nodes were distributed evenly across all lymphatic areas and there was no correlation to the extent and the kind of carcinoma. In most cases the benign nature of these inclusions was obvious even in the presence of metaplasias and there was no difficulty in differentiating them from metastases.

Toxic shock syndrome is a multisystem disease which presents with a high fever, rash, gastrointestinal symptoms, and hypotension. A 58-year-old woman presented to the emergency room with these symptoms, hypotension and tachycardia. Because of vaginal spotting a pelvic examination was performed which demonstrated vulvo/vaginal erythema and a large vaginal mass consistent with an advanced cervical cancer with bilateral pelvic sidewall fixation. Cervical/vaginal biopsy demonstrated invasive squamous cell carcinoma and an initial chest X ray demonstrated multiple pulmonary metastases. After a total of 8 days of antibiotic therapy the patient received cis-platinum chemotherapy. The toxic shock syndrome was the presenting symptomatology in this patient with advanced cervical cancer. Toxic shock syndrome has been associated with the use of hyperabsorbent tampons as well as numerous other gynecologic procedures but has not been reported in patients with gynecologic cancer.

Radioimmunoscintigraphy (RIS)--using radiolabeled monoclonal antibodies (MoAbs) to image disease--is a growing subspecialty of nuclear medicine. RIS of the reproductive tracts of men and women has shown encouraging results in imaging both primary lesions and metastases of these cancers. Ovarian cancer is the most fatal gynecologic cancer in the United States, and prostate cancer is the most prevalent form of cancer in men. Several MoAbs against reproductive tumor antigens were used with limited success in clinical trials before 1989. Most recently, MoAbs CYT-103 (satumomab pendetide) and OV-TL 3 have shown promise as safe, sensitive imaging tools for ovarian cancer. Although to date more agents have been used to image ovarian carcinoma than prostate cancer, research has been restimulated in prostate carcinoma imaging because of development of a promising MoAb conjugate, CYT-356. Radionuclide indium-111 appears to be the most promising radiolabeled to date for ovarian and prostate carcinoma RIS performed in the United States. In future clinical trials, consideration of safety issues and a standardization of methods among institutions using RIS are needed before the use of MoAb technology in cancer imaging will become routine. Comparative studies with more traditional methods like computed tomography are needed, as well as more trials comparing radioimmunoscintigraphic findings with pathological evidence.

Epithelial ovarian carcinoma, the leading cause of gynecologic cancer death, is characterized by widespread intra-abdominal metastases mediated primarily by surface shedding of tumor cells and peritoneal implantation. Whereas hematogenous metastasis is known to involve cellular adhesion, extracellular matrix proteolysis and cell migration, the role of these processes in the intraperitoneal dissemination of ovarian cancer remains unclear. To analyze further the role of adhesion and proteolysis in ovarian carcinoma dissemination, we have characterized the adhesive profiles of 4 primary cultures of ovarian carcinoma cells and 5 ovarian carcinoma cell lines. Our data demonstrate preferential adhesion of ovarian carcinoma cells to interstitial type I collagen. Analysis of adhesion molecule expression demonstrated the presence of the alpha2 and beta1 integrin subunits by cell surface ELISA, immunoprecipitation and immunohistochemistry. Furthermore, antibodies directed against the alpha2 and beta1 subunits inhibited adhesion of ovarian carcinoma cells to type I collagen by 56% and 95%, respectively. Plasminogen activator and matrix metalloproteinase production by adherent cells was not altered as a consequence of adhesion to individual extracellular matrix proteins; however, adhesion to an extracellular matrix comprised primarily of interstitial collagen increased plasminogen activator activity in 5 of 5 cell lines. Since the ovarian carcinoma micro-environment is rich in type I collagen, our data suggest that preferential adhesion to type I collagen followed by secretion of serine and metalloproteinases may represent a biochemical mechanism by which the intraperitoneal dissemination of ovarian carcinoma is mediated.
