Abstract
Five cases of primary vaginal melanoma were treated at UCLA Medical Center between 1976 and 1986. Two additional cases of melanoma arising at the junction of the vulva and vagina are presented. One of seven (13%) patients is alive, with a median time to recurrence of 7 months, and median survival of 31 months. Four of five vaginal melanomas were located in the distal vagina, and all were advanced at diagnosis (greater than 3 mm depth). Mean size was 3 cm. Initial therapy was local excision in four patients and radical surgery in three. All patients had suboptimal surgical margins: two vaginal primaries had positive margins after local excision, both recurred vaginally within 5 months. Two patients had margins less than 1 mm, one died of distant metastases, the other is alive with disease 30 months after radical distal vaginectomy and hemivulvectomy with post-op pelvic radiotherapy. Three patients had melanoma in situ at the surgical margins, and each had pelvic recurrences between 6 and 26 months. Five of seven cases developed local recurrence as the initial site of treatment failure. All five vaginal cases ultimately developed distant disease, but only two patients had distant disease without local-regional recurrence. Chemotherapy and immunotherapy enabled disease stabilization in three patients. The vulvovaginal junction at the introitus is a high risk site for vaginal and vulvar melanoma. Intraoperative management requires assessment of lateral and deep spread of invasive and in situ melanoma.

Abstract
An analysis was performed of malignant and host cells found in peritoneal fluids obtained during intraperitoneal chemotherapy and immunotherapy in patients with ovarian cancer. The concentration of malignant cells and the surgically documented response to the intraperitoneal treatment were correlated. Twenty-three patients were treated with intraperitoneal cisplatin or alpha-2 interferon (rIFN-alpha 2) after persistent carcinoma was documented at second-look laparotomy. Six patients (26%) had a complete response to therapy, and all of these patients had a malignant cell concentration of less than 10(2)cells/cm2/dL. No responses were seen in patients whose initial malignant cell concentration was greater than 10(3)cells/cm2/dL. Among patients treated with intraperitoneal alpha-interferon, five of 11 whose initial concentration of malignant cells was less than 10(2) cells/cm2/dL responded to therapy, whereas none of the patients whose malignant cell concentration was 10(2) cells/cm2/dL or greater responded. In patients treated with intraperitoneal cisplatin, the initial concentration of malignant cells associated with any surgically documented response was less than 10(3)cells/cm2/dL. A host mesothelial reaction was prominent after intraperitoneal alpha-interferon, but not observed in women treated with intraperitoneal cis-platin. The fluctuating pattern of peritoneal white blood cells documented during therapy did not correlate with response. THe evaluation of peritoneal cytology specimens during intraperitoneal chemotherapy should include a quantitative assessment of malignant cells and reactive mesothelial cells in order to reflect more accurately the histologically documented findings. Initial quantitative cytology appears to correlate with the likelihood of a surgically documented response to intraperitoneal therapy.

Abstract
Eleven patients with persistent Stage III ovarian cancer, documented at second look laparotomy, received i.p. human recombinant interferon-alpha (5-50 x 10(6) units/week). Prior to immunotherapy, patients' peritoneal cell lymphocytes (PCLs) contained decreased proportions of Leu-7+ and Fc-receptor+ cells and almost nondetectable natural killer (NK) and antibody-dependent cell cytotoxic (ADCC) activity. In contrast, patients' peripheral blood lymphocytes (PBLs) contained normal proportions of lymphocyte subsets and cytotoxic activity compared to control donor PBLs. During therapy, there was a concurrent increase in PCL Leu-7+ cells and NK lysis. Both peaked predictably at 24 h after each treatment, regardless of the dose injected, and usually returned to baseline by Day 7 of each weekly cycle. PCL NK enhancement was striking, usually increasing from 2-6% (effector:target ratio, 25:1) to over 30% lysis. Enhancement of PCL ADCC was less impressive. PCLs of several patients developed lytic activity towards NK-resistant Raji targets. During therapy, patients' PBLs demonstrated: (a) modestly enhanced NK lysis at Day 4 of each cycle, and; (b) no development of Raji lysis. These data clearly demonstrate the efficacy of i.p. interferon in activation of peritoneal NK activity. However, increased NK lysis did not correlate with individual tumor responses in this cohort of patients.

Abstract
CA 125 levels were measured in 158 patients with palpable pelvic masses who were about to undergo diagnostic laparotomy. When the 68 patients found to have cancer were compared with the 90 patients with benign disease, those with malignancies were significantly older, were more frequently postmenopausal, and had significantly higher values of serum CA 125. Patients with benign pelvic masses had CA 125 levels greater than 65 U/ml in 8% of cases, whereas those with malignancies had CA 125 levels greater than 65 U/ml in 75% of cases. If only those patients who had frankly malignant, primary, nonmucinous epithelial ovarian carcinomas were considered, CA 125 levels greater than 65 U/ml predicted malignancy with a sensitivity of 91% for all patients. Greater sensitivity and specificity were observed in the postmenopausal subgroup than in the premenopausal subgroup. In the postmenopausal group with a 63% prevalence of ovarian cancer the predictive positive value was 98% and the predictive value negative was 72%. In a premenopausal population with a 15% prevalence of ovarian cancer the predictive value for a positive test was 49%, while the predictive value for a negative test was 93%.

Abstract
Cancers of the cervix and uterus occur in approximately 50,000 women each year in the United States. As a group, these cancers represent our sixth most common cancer overall, are second only to breast cancer, and are roughly equal to the lung cancer incidence in women. Although they comprise 11% of all cancers in females, they represent only 4% of cancer deaths in women. This results from the effective application of surgery and radiation therapy in the management of these two malignancies as well as effective techniques for early diagnosis. The overall death rate from these two malignancies has decreased more than 70% in the last 40 years. Successful outcome rests on both early diagnosis and the careful application of established treatment approaches. This monograph summarizes the management approaches to both uterine corpus and cervical cancer and discusses the role of adjuvant therapy for these major malignancies. Detailed presentations of the management of special problems, including the uterine sarcomas, are also presented. Although standard management approaches are detailed, discussion of experimental approaches, including adjuvant hormonal treatment, single agent and combination chemotherapy, and the use of radiation sensitizers is included.

Abstract
Adenocarcinoma of the uterine cervix appears to be more prevalent now than a decade ago, and currently constitutes 10-20% of invasive cervical cancers. Because precursor lesions arise within the endocervical canal, identification and diagnosis of invasive disease is often more difficult than for squamous carcinoma. There is disagreement regarding the optimal treatment of adenocarcinoma. Adenocarcinoma may have a poorer prognosis than squamous carcinoma because it may be more difficult to detect and because it tends to metastasize earlier in its course. The controversies in the diagnosis and management of adenocarcinoma and adenosquamous carcinoma of the uterine cervix are reviewed.

Abstract
The in vitro sensitivity to rTNF, rIFN-alpha 2, and OK-432 of 11 freshly derived human ovarian tumors and 2 established tumor cell lines was examined in a cytotoxic assay using the 51 Cr release test. Nine fresh lines were sensitive to rTNF, 8 to OK-432, and only 2 were sensitive to rIFN-alpha 2. Cytotoxicity by rIFN-alpha 2 was of lesser magnitude than the cytotoxicity mediated by rTNF or OK-432. The time of exposure and the concentration of BRM required for maximal cytotoxicity varied from line to line. Two fresh tumor cell lines and 1 established cell line (PA-1) were sensitive to all 3 BRMs, while 2 other FOCs and 1 cell line (SKOV-3) were resistant to all BRMs. The remaining FOC showed an intermediate degree of sensitivity. These results demonstrate the existence of heterogeneity of ovarian carcinoma tumor cell lines to lysis by BRMs. Among the FOCs, the 2 endometrioid carcinomas tested were highly sensitive to rTNF, whereas the serous carcinomas were more sensitive to OK-432. Low grade tumors were more sensitive to BRM than high grade tumors, and tumor extension did not correlate with sensitivity to the BRM. When tumor targets were exposed to more than 1 BRM added either simultaneously or sequentially, the net cytotoxic effect achieved was usually inferior to the sum cytotoxicity obtained by each BRM alone. Furthermore, rTNF and OK-432 were cytostatic to most ovarian tumor cell lines examined. The results of this study demonstrate that certain BRMs exert a direct effect on fresh ovarian tumor cells independently of host factors. These findings suggest that in vitro screening of a patient's tumor cells for sensitivity to a particular BRM prior to therapy could be beneficial for the proper identification of patients most likely to benefit from the treatment.

Abstract
Eighteen patients with residual epithelial ovarian cancer at second-look laparotomy were treated with a combined total of 210 cycles of intraperitoneal cis-platinum. Sixteen patients had previously received cis-platinum containing combination chemotherapy systemically. Seven patients had microscopic residual disease at the start of intraperitoneal therapy, eight had macroscopic disease of 5 mm in diameter or less, and three had disease of 6-10 mm in diameter. The drug was administered weekly in 2 L of Ringer's lactate solution via an indwelling Tenckhoff catheter, and the dose ranged from 30-270 mg per cycle (median 120 mg). The dwell time was 20 minutes. After 12 cycles, response was assessed by open laparoscopy (six patients), laparotomy (eight patients), or peritoneal cytology (three patients). One patient developed distant metastases. Local and systemic toxicity was mild. Delays of therapy were necessary for eight of the 210 cycles because of hematologic toxicity. Of the 15 patients available for pathologic evaluation, four (26.6%) had a complete response and two (13.3%) had a partial response. Results of this pilot study suggest a possible role for intraperitoneal cis-platinum in the management of carefully selected patients with epithelial ovarian cancer.

Abstract
Twenty-one cases of sarcoma botryoides of the uterine cervix, including four previously unreported cases, are reviewed. The age of the patients ranged from 5 months to 48 years, with a peak incidence in the group aged 14 to 18 years. Eighty percent of the patients are alive, with a mean follow-up period of 68 months. Seventy-five percent of the patients had Group I disease, of whom 88% are alive. Eleven of 14 patients (79%) receiving vincristine and dactinomycin based chemotherapy are alive. There were five patients with recurrent disease (24%) of whom two (40%) are alive. The prognosis for cervical sarcoma botryoides is similar to that of other female genital tract embryonal rhabdomyosarcomas. Primary therapy should consist of vincristine and dactinomycin based chemotherapy. Surgery should be guided by the response to initial chemotherapy and should attempt to conserve the function of the bladder, rectum, vagina, and ovaries.

Abstract
A review of 255 patients with epithelial ovarian carcinoma revealed that metastases consistent with Stage IV disease developed in 97 patients (38.0%) at some time during the natural history of their disease. Malignant pleural effusions developed in 63 patients (24.7%), and their median survival (from the time of diagnosis of the effusion) was 6 months. Parenchymal liver metastases developed in 24 patients (9.4%; median survival, 5 months); parenchymal lung metastases in 18 patients (7.1%; median survival, 8 months); distant lymph node metastases in 18 patients (7.1%; median survival, 9 months); subcutaneous nodules in nine patients (3.5%; median survival, 12 months); a malignant pericardial effusion in six patients (2.4%; median survival, 2.3 months); central nervous system metastases in five patients (2%; median survival, 1.3 months); and bone metastases in four patients (1.6%; median survival, 4 months). Patients with Stage IV disease at the time of diagnosis had a median survival of 9.1 months, while patients with a delayed occurrence of distant metastases had a median survival of only 4 months from the time of diagnosis of the distant metastases. Significant risk factors for distant metastases were malignant ascites, peritoneal carcinomatosis, large metastatic disease within the abdomen, and retroperitoneal lymph node involvement at the time of the initial surgery. The significance of positive retroperitoneal nodes and bulky upper abdominal disease has important therapeutic implications.

Abstract
In an effort to improve the prognostic accuracy of the histologic criteria used for cervical adenocarcinomas, the nuclear DNA ploidy levels, means and standard deviations of nuclear areas and amounts of lumen and neoplastic tissue were quantitated. Useful thresholds in discriminating recurrent disease, as identified by logistic regression analysis, included a DNA ploidy level of 3.0 N, a percent of lumen of 34.6% and nuclear area mean and standard deviation of 53.1 sq micron and 20.1 sq micron, respectively. These parameters should provide useful guidelines in the visual assessment of histologic features that have prognostic significance.

Abstract
This report describes the detection of human papillomavirus type 16 or 18 deoxyribonucleic acid (DNA) in nine of 15 invasive tumors of the cervix, including three squamous carcinomas, four adenosquamous carcinomas, one glassy cell carcinoma, and one adenocarcinoma. The viral DNA was identified by Southern blotting and DNA hybridization. Human papillomaviruses may play an etiologic role in the development of at least some adenocarcinomas and adenosquamous carcinomas as well as most squamous tumors of the cervix.

Abstract
Serum CA 125 levels were obtained from 55 women with epithelial ovarian cancer before a second-look surgical procedure and serially thereafter. All patients were clinically and radiographically free of tumor at the time of the second-look operation and were followed to clinical recurrence. Median follow-up was 12 months. CA 125 levels obtained at the second-look operation had a sensitivity and specificity for predicting clinical recurrence of 94% and 88%, respectively. Patients with an elevated CA 125 level (greater than or equal to 35 U/ml) had a 60% chance of clinical recurrence within 4 months, while patients with levels less than 35 U/ml had a 5% chance of clinical recurrence over the same time period. Serial CA 125 levels obtained after second-look operations were strong predictors of clinical outcome, and distinctly different monitoring profiles were observed among those patients remaining clinically free of tumor and those suffering clinical recurrence. The CA 125 assay became elevated (greater than or equal to 35 U/ml) before clinical recurrence in 94% of 35 cases with a median lead time of 3 months. The CA 125 assay identifies patients destined to suffer a clinical recurrence and provides a warning measurable in months. This may have important implications for therapy.

Abstract
Between 1974 and 1984, 70 patients underwent primary cytoreductive surgery for ovarian carcinoma at the University of California at Los Angeles. During the period of January 1974 to December 1978, optimal cytoreduction was achieved in 56.4% of the patients. With increased experience, this figure improved to 87.1% in the period of January 1979 to December 1983. The most common morbidity associated with the procedure was fever and prolonged ileus. Bowel resection was required in 20% of the patients and was not associated with increased morbidity. More liberal use of the end-to-end anastomosis stapling device facilitated low colon reanastomosis without colostomy, which contributed to the improved patient acceptance.

Abstract
CA 125, which is an antigenic determinant expressed by many epithelial ovarian cancers, is measured in serum using a solid phase immunoradiometric assay. Sera from 55 patients who were in clinical remission and underwent a second-look operation to assess disease status after chemotherapy were studied prospectively. All patients had the CA 125 assay performed within one week before their second-look operation. Twenty-four patients (44%) had no histologic or cytologic evidence of disease, seven patients (13%) had microscopic disease, 13 patients (24%) had disease measuring 1 mm to 1.5 cm, and ten patients (18%) had disease greater than or equal to 1.5 cm in maximum tumor dimension. None of the 24 patients with a negative second-look operation had a positive CA 125 antigen level (greater than or equal to 35 U/mL), compared with six of 20 patients (30%) with less than 1.5 cm disease, and six of ten (60%) with greater than or equal to 1.5 cm disease (P less than .0001). All 12 patients with an elevated CA 125 antigen level (greater than or equal to 35 U/mL) had disease discovered at their second-look operation. Thus, in this setting the predictive value of a positive CA 125 titer (greater than or equal to 35 U/mL) was 100%. The predictive value of a negative CA 125 antigen level (less than 35 U/mL) was 56%, ie, the test did not exclude the presence of disease in 44% of patients with a positive second look. The maximum tumor size associated with at least one prior negative antigen level was 1.9 cm.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Twenty-six patients with advanced or recurrent cancer of the vagina no longer amenable to control with surgery and/or radiotherapy were entered into a phase II study of cisplatin 50 mg/m2 intravenously every 3 weeks. Two were deemed ineligible because of a primary site of origin other than vagina. Two were deemed inevaluable, one because of the lack of measurable disease and the other because she never received drug. The remaining 22 included a variety of histologies (16 squamous cell carcinomas, 2 adenosquamous carcinomas, 1 clear cell carcinoma, 1 leiomyosarcoma, and 2 carcinomas not otherwise specified). One complete responder was observed among the 16 patients with squamous cell carcinoma. Adverse effects were tolerable and were essentially those reported in other series. These results suggest that cisplatin has insignificant activity in advanced or recurrent squamous cell carcinoma of the vagina at least at the dose and schedule tested. No comment can be made regarding the activity of cisplatin in other histologies.

Abstract
Fourteen patients with epithelial ovarian cancer were treated with intraperitoneal (i.p.) administration of alpha-recombinant interferon (rIFN-alpha 2) after documentation of persistent disease at second-look laparotomy and combination chemotherapy. After therapy, 11 patients had a surgical re-evaluation which confirmed 4 complete responses (36%), 1 partial response (9%), and disease progression in 6 (55%). Five of 7 patients (71%) with minimal residual disease (MRD, i.e. less than 5 mm) had a surgically-documented response, whereas there was none in the 4 patients whose tumors were greater than or equal to 5 mm. Fever greater than or equal to 38 degrees C was seen in 58%, greater than or equal to 39.0 degrees C in 18%; nausea and vomiting in 37%, and abdominal pain in 22%. There was no consistent alteration in peripheral WBC's during treatment, while i.p. monocytes and lymphocytes showed a significant boost on day 1 after each dose of rIFN-alpha 2. Natural killer (NK) lymphocyte cytotoxicity was elevated in the i.p. cavity fluid obtained from most patients on day 1 after treatment, while blood NK values showed considerable variability. Pharmacokinetic studies showed i.p. levels of rIFN-alpha 2 were 30-1000 times blood levels. I.p. rIFN-alpha 2 may act by increasing concentrations of drug and augmenting regional host cells in patients with MRD ovarian cancer.

The initial dose was 5 X 10(6) units which was escalated weekly to 50 X 10(6) units over 4 weeks and then continued weekly for a total of 16 weeks. Eleven patients underwent surgical reevaluation after therapy which confirmed four pathological complete responses (36%), one partial response (9%), and disease progression in six patients (55%). Five of seven patients (71%) with residual tumor less than 5 mm had a surgically documented response, whereas there was no response in the four patients whose tumors were greater than or equal to 5 mm. Three patients were evaluable for clinical response only: one patient who refused surgery had a complete clinical response with total resolution of ascites; one had stable disease; and one had disease progression. Fever greater than or equal to 38 degrees C was seen in 58%, fever greater than or equal to 39.0 degrees C was seen in 18%, vomiting in 37%, abdominal pain was reported in 22%, and one patient had infectious peritonitis. Peripheral white blood cell counts and i.p. washings were obtained pretreatment and on days 1, 3, and 7 after treatment. While there was no consistent alteration in peripheral white blood cell counts, the numbers of i.p. monocytes and lymphocytes showed a significant boost on day 1 after each dose of rIFN-alpha 2. Natural killer lymphocyte cytotoxicity was elevated in the i.p. cavity fluid obtained from most patients on day 1 after treatment, while blood natural killer lymphocyte cytotoxicity values showed considerable variability. Pharmacokinetic studies show that i.p. levels of rIFN-alpha 2 were 30-1000 times blood levels. rIFN-alpha 2 i.p. may act by increasing concentrations of drug and augmenting regional host cells in patients with minimal residual ovarian cancer.

Abstract
The antitumor effects of Corynebacterium parvum in a murine ovarian teratocarcinoma model depend upon a sequential activation of neutrophils and macrophages within the peritoneal cavity. We studied the sequential administration of biological response modifiers that independently activate each phase of the response. Tumor-challenged mice treated by i.p. injection of a pyridine-extracted fraction of cell-free Propionibacterium acnes (PA-PE, 1400 micrograms) demonstrated prolonged survival in less than 20% of the cases. An i.p. injection of a detoxified Salmonella endotoxin (DSE) preparation (150 micrograms) had no effect on tumor outgrowth. However, i.p. treatment with PA-PE (1400 micrograms), followed by 150 micrograms of DSE 1 day later, resulted in long-term survival (greater than 100 days) in 40 to 60% of mice. This antitumor effect was only evident when PA-PE was administered first (before DSE) and optimal when DSE was administered 24 h after PA-PE. The synergistic antitumor effect could be duplicated when tumor-challenged mice were first treated i.p. with peritoneal polymorphonuclear leukocytes, elicited by injection of PA-PE, and then treated with DSE 18 h later. These data indicate that appropriately timed injection of biological response modifiers with complementary effects can result in a synergistic prevention of tumor growth.

Abstract
Thirty patients found to have residual epithelial ovarian cancer at second-look laparotomy were treated with whole abdominal radiation as salvage therapy. Dosage fractions were 120 rad per day until 3000 rad were delivered, then the pelvis was boosted to 5000 rad at 180 rad per day. Fourteen patients (47%) completed therapy without interruption and seven (23%) completed therapy with interruptions due to myelosuppression ranging from one to four weeks. Therapy was not completed in nine patients (30%). Four of 16 patients (25%) with microscopic residual disease before radiation remain alive and free of disease at 22 to 41 months. Two of six (33%) patients with minimal (less than or equal to 5 mm) residual disease remain alive and free of disease 19 to 40 months after radiation treatment. Patients with residual nodules greater than 5 mm uniformly did poorly. Patients who progressed on primary chemotherapy had a median survival of seven months, compared with more than 38 months for chemotherapy responders. Chronic bowel morbidity was a significant problem, with 30% of patients surviving at least four months from completion of radiation requiring laparotomy for small bowel obstruction. These preliminary results suggest that whole abdominal radiation may be useful in the management of patients who have responded to primary chemotherapy, but the benefit is confined to those patients who have minimal or microscopic disease at second-look laparotomy.

Abstract
One hundred and two patients were treated for primary adenocarcinoma of the uterine cervix over a ten-year period from 1973 to 1982. Of these, 51 patients underwent initial surgical management that included a pelvic and para-aortic lymphadenectomy with a radical hysterectomy or a surgical staging operation. Clinical lesion size, grade, and depth of stromal invasion were correlated with lymph node metastasis and survival. The incidence of positive lymph nodes was 14.6% for stage I and 40.0% for stage II. Positive lymph nodes were documented in none of 15 patients with lesions smaller than 2 cm, 16.7% (five of 30) with 2 to 4 cm, and 82.3% (five of six) with larger than 4 cm; 5.3% of grade 1 tumors, 11.1% of grade 2, and 50.0% of grade 3. There were no lymph node metastases (zero of six) in patients with a tumor that had a depth invasion of less than 2 mm, whereas positive nodes were found in 11.1% (two of 18) patients with 2 to 5 mm of invasion, 28.6% (two of seven) with 5 to 10 mm, and 57.1% (four of seven) with greater than 10 mm of invasion. Five-year survival was 82.9% for stage I and 42.9% for stage II patients; 91.7% with negative lymph nodes, and 10% with positive nodes (P less than .0001). The size of the primary tumor (P less than .0001), tumor grade (P less than .05), and depth of invasion (P less than .05) correlated with patient survival.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Eight patients with locally advanced vulvar cancer that would have necessitated pelvic exenteration to encompass the primary tumor were given preoperative radiation therapy in an attempt to shrink the primary tumor and allow more conservative surgery. From 4400 to 5400 rad of external radiation were delivered to the primary tumor, and one patient received an additional 2400 rad from intracavitary therapy. Satisfactory shrinkage of tumor occurred in seven of the eight patients (87.5%), thus allowing conservative surgical excision. In four patients (50%), there was no viable tumor in the surgical specimen. Moist desquamation of the vulva occurred in all patients and was of sufficient severity to require temporary cessation of radiation in four patients (50%). Five received groin radiation, and one (20%) subsequently developed bilateral hip fractures. No other major morbidity occurred. Five of the eight patients (62.5%) are alive without evidence of disease at intervals ranging from 15 months to 10 years. Preoperative radiation in this group obviated the need for pelvic exenteration, resulting in significantly less morbidity without compromising survival.

Abstract
After an intensive course of combination chemotherapy, 16 patients with minimal residual ovarian cancer that was documented at second-look laparotomy, had an indwelling Tenckhoff catheter placed and underwent multiple peritoneal saline lavages. Lymphocyte-enriched populations from the peritoneal cavity and peripheral blood were obtained by density gradient centrifugation and examined for cell-surface phenotype and a variety of immune functions, including natural killer cytotoxicity and antibody-dependent cell-mediated cytotoxicity. Phenotypic characterization revealed that peritoneal lymphocytes consisted primarily of T cells and cells bearing receptors for the crystallizable fragment of immunoglobulin G (IgG) (crystallizable fragment-receptor), and contained a very low number of B cells. Peritoneal natural killer lymphocyte cytotoxicity and antibody-dependent cell-mediated cytotoxicity were very low in all but two patients. Incubation of peritoneal lymphocytes with Corynebacterium parvum and interferon in vitro did not result in augmented cytotoxicity against susceptible targets. Supernatants from cultured peritoneal cells of all patients markedly inhibited natural cytotoxic activity of normal donor blood lymphocytes. These results suggest that lymphocytes collected from the peritoneal cavity of patients with minimal residual ovarian cancer are deficient in natural and antibody-dependent cytotoxic effector function. This deficiency may influence the host's ability to control the spread and proliferation of tumor cells in the peritoneal cavity.

Abstract
From 1976 through 1982, 72 rectosigmoid colectomies were performed on patients treated at the gynecologic oncology service at UCLA. Thirty-five of these were performed to resect primary or recurrent ovarian cancer, and 37 were performed as part of an exenteration for recurrent cervical or vaginal carcinoma. In 24 of the patients with ovarian cancer and 11 of the patients undergoing exenteration, the rectosigmoid colon was primarily reanastomosed, using either a primary suture technique or the end-to-end anastomosis stapler. Intraoperative management included adequate mobilization of the colonic mesentery to eliminate tension on the anastomosis, and liberal use of pelvic drains. Eighteen of 24 (75%) patients with ovarian cancer who received a primary reanastomosis did not have a protecting colostomy, whereas all 11 patients who underwent exenteration had a protecting colostomy. There were no anastomotic leaks in any of these patients, although morbidity occurred in seven of 35 patients (20%). There were no operative mortalities. The end-to-end anastomosis stapler has facilitated lower resections with primary reanastomosis. Colostomy is not mandatory in patients who have not had prior pelvic radiation therapy, and in whom no pelvic infection exists. Rectosigmoid colectomy permitted optimal or curative tumor resection in the majority of these patients, and thus should be performed whenever necessary to accomplish this goal.

Abstract
Variables associated with a negative second-look laparotomy in patients with stage III epithelial ovarian carcinoma are analyzed. Fifty-six patients were clinically free of disease after systemic chemotherapy and were subjected to second-look laparotomy to assess tumor status. Eighteen of these patients (32.1%) had no evidence of malignancy. Eight (14.3%) additional patients with no gross evidence of disease at laparotomy had microscopic persistence; five of these had disease documented in the pelvic or para-aortic lymph nodes. Significant variables associated with a histologically and cytologically negative second-look operation were low tumor grade (P less than .01), the use of cis-platinum containing combination chemotherapy (P less than .01), patient age less than or equal to 50 years (P less than .02), small residual tumor (less than 0.5 cm) before chemotherapy (P less than .05), and metastatic tumor less than or equal to 10 cm before initial cytoreduction (P less than .05). Patients treated with six to nine cycles of combination chemotherapy had the same probability of a negative second-look laparotomy as those treated with ten to 12 cycles. Multivariate discriminate analysis indicated that patients with low tumor grade, those receiving cis-platinum containing combination chemotherapy, and those with minimal residual tumors (less than 0.5 cm) after primary cytoreductive surgery correctly classify second-look status in 78.6% of patients. Until a nonsurgical method of monitoring subclinical disease is available, a through second-look laparotomy, including a pelvic and para-aortic lymphadenectomy, should be performed.

Abstract
The antitumor effect of two strains of Propionibacterium acnes (PAI and PAII) and chemically derived fractions from the whole bacterial cell were studied using a murine ovarian teratocarcinoma (MOT) model. When injected i.p. in high doses (700 to 1400 micrograms/mouse), both strains produce survival of a significant proportion of tumor-bearing mice (30 to 90%). On a weight to weight basis, however, PAI was significantly more effective than PAII. PAI and PAII were extracted using pyridine, which yielded four fractions, i.e., pyridine-extracted strains PAI and PAII (PA-PEI and PA-PEII, respectively) which are composed of the cell wall material extracted by pyridine, and the residues of PA-PEI and PA-PEII (PA-RI and PA-RII, respectively) which are composed of the residue material following the chemical extraction. The chemical composition of PA-PEI was different from that of PA-PEII (the latter had proportionately three times as many carbohydrates and one-third of the protein content of the former) and so were their antitumor properties in the MOT model. PA-PEI had markedly reduced antitumor effect when compared to the untreated cell on a per weight basis. Furthermore, curability was only seen when using a high dose (1400 micrograms/mouse). By contrast, the cell wall components extracted by pyridine from PAII (PA-PEII) had powerful antitumor effects, i.e., greater than 50% of mice given 1400-micrograms injections survived. The material contained in PA-PEII was further fractionated on the basis of its organic solubility in chloroform:methanol solvent. The water-soluble and solvent-insoluble fractions retained most of the antitumor effects of PA-PEII, while the water-insoluble and solvent-soluble fractions were only moderately effective, suggesting that the active moiety(ies) was associated with the nonlipid components of this fraction. Both residue fractions (PA-RI and PA-RII) were as effective on a per weight basis in controlling the growth of 10(5) tumor inoculum as were whole untreated cells. However, periodate oxidation of PA-RI resulted in complete loss of its antitumor effects. When surviving mice that had no evidence of tumor persistence following a tumor challenge (10(5) MOT cells) and i.p. treatment with PA were subsequently rechallenged with 10(4) tumor cells, survival was significantly prolonged, as compared to tumor-challenged (10(4) MOT) naive mice. In addition, 10 to 20% of these rechallenged mice had complete eradication of the tumor inoculum (no evidence of disease for greater than 120 days).(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Twenty-eight patients underwent vaginal reconstruction simultaneously with pelvic exenteration performed for recurrent pelvic malignancy. A satisfactory neovagina was created in 24 (86%) patients. Successful bilateral grafting was accomplished in 18 of 21 (86%) patients using gracilis myocutaneous grafts. Seven patients had a split-thickness skin graft, most of which was combined with an omental pedicle graft; six of these patients had a satisfactory neovagina. None of the patients developed herniation of the bowel through the reconstructed pelvic floor, or fistulas in the absence of recurrent malignancy. The gracilis myocutaneous graft is most feasible in patients in whom total pelvic exenteration is performed, whereas a split-thickness graft is preferable in those patients who undergo anterior exenteration or who have rectosigmoid reconstruction using low colon reanastomosis.

Abstract
Of 177 cases of invasive squamous cell vulvar cancer seen at the University of California at Los Angeles and the City of Hope National Medical Center from 1957 to 1980, 84 (47.5%) had stage I disease. Seventy-seven patients with stage I disease (91.7%) had stromal invasion of 5 mm or less. Correlation between lymph node status and depth of invasion was as follows: 1 mm or less, none of 34 (0%); 1.1 to 2 mm, two of 19 (10.5%); 2.1 to 3 mm, two of 17 (11.8%); 3 to 5 mm, one of seven (14.3%); more than 5 mm, three of seven (42.9%). Fifty-six patients had radical vulvectomy for the primary lesion, and 28 had more conservative excision, but the incidence of local invasive recurrence (4%) was the same in each group. None of 58 patients treated with inguinal-femoral lymphadenectomy developed a groin recurrence, but three of 26 patients (11.5%) who had omission or modification of inguinal-femoral lymphadenectomy died with groin recurrence within 12 months. These data suggest that although some modification of the standard radical vulvectomy is appropriate for the primary lesion in patients with stage I disease, patients with greater than 1 mm of stromal invasion require at least an ipsilateral inguinal-femoral lymphadenectomy.

Abstract
Four patients with small residual ovarian carcinoma following treatment with cisplatin, doxorubicin, and cyclophosphamide have subsequently received 57 courses of ip cisplatin. Cisplatin (120-270 mg in 2 L of Ringer's lactate) was administered via Tenckhoff catheter, with a dwell time of 15-20 mins. Courses were given weekly for 12 weeks, with response documented by laparoscopy or laparotomy prior to and following the trial. With a dwell time of 20 mins, 75% +/- 5% (mean +/- SD) of platinum was recovered. With 120 mg of cisplatin and a dwell time of 20 mins, total plasma platinum peaked at 1.23 +/- 0.42 microgram/ml and by 8 hrs decreased to 0.67 +/- 0.12 microgram/ml. Filterable (non-protein-bound) platinum peaked at 0.73 +/- 0.21 microgram/ml and by 8 hrs fell to 0.03 microgram/ml. Excretion rate paralleled the filterable plasma curve, peaking at 40 mins; 30% +/- 7% of absorbed drug was recovered in urine within 24 hrs. Renal clearance of filterable platinum was 106 +/- 20 ml/min. Creatinine clearance was 76 +/- 7 ml/min. Three responses, one complete and two partial, were noted. Zero to two episodes of vomiting occurred in each course. One patient had a creatinine clearance decrease to 40 ml/min, one had two episodes of thrombocytopenia, and one had mild abdominal pain with a cisplatin dose of greater than or equal to 210 mg. No neurotoxicity, catheter infection, or peritonitis was encountered.

Abstract
Since operative evaluations of patients undergoing therapy for ovarian cancer are necessary, the laparoscope will continue to play a role in the management of these patients. However, the sensitivity of the laparoscope for detecting disease either prior to or at the completion of chemotherapy is significantly less than that of laparotomy, and therefore its utility must be more narrowly defined. The morbidity of laparoscopy is low when performed correctly and utilizing techniques to avoid bowel perforation. Most patients require only a brief hospitalization, and those who cannot medically tolerate an extensive laparotomy might be able to undergo a laparoscopy. The major limitations of laparoscopy are the inability to adequately inspect the peritoneal cavity and pelvis in at least one-quarter of patients because of extensive adhesions, to assess retroperitoneal lymph nodes in all patients, and to resect tumour masses necessary to cytoreduce the tumour prior to therapy. The successful performance of interval laparoscopy, however, is predictive of survival and can select a group of patients whose likelihood of recurrence is relatively low (30 per cent) after more than three years. The observation that the majority of patients who have a negative laparoscopy following six months of chemotherapy remain free of disease for several years, suggests that sensitive tumours are most likely to respond during the initial courses of chemotherapy, and that consideration should be given to briefer and more intensive courses of therapy prior to operative evaluation of the patients.

Abstract
The cytoplasmic receptors for 17 beta-estradiol (ER) and progesterone (PR) were measured in 39 malignant and 15 benign ovarian neoplasms. All eight endometroid carcinomas had positive ER sites, one-half contained PR. The number of ER binding sites decreased as tumor grade increased. Conversely, none of the 11 mucinous tumors contained either ER or PR receptors. One-half of the well-differentiated serous tumors had ER (57 +/- 23 fmole/mg protein) while none of the poorly differentiated tumors had measurable binding. In serous carcinomas, PR was only detected in well-differentiated lesions (447 +/- 240 fmole/mg protein). Only one of 15 benign neoplasms contained ER and PR receptors. Correlation of tumor grade and type may help to plan hormonal therapies in advanced ovarian malignancies.

Abstract
Vaginal reconstruction was performed in 14 patients who had developed vaginal stenosis secondary to extensive pelvic fibrosis after pelvic radiation therapy (12 patients) or prior vaginal reconstruction (2 patients). Sixteen procedures were performed using a split-thickness skin graft. All patients had satisfactory vaginal restoration, and 12 patients reported good vaginal function. No fistula developed as a result of the operative procedure, but one patient later developed a rectovaginal fistula resulting from tumor recurrence. Successful vaginal reconstruction can be achieved even years after initial therapy in patients who develop an obliterated vagina from previous radiation or surgery.

Abstract
Forty-seven patients with stage III or IV invasive epithelial carcinoma of the ovary underwent primary cytoreductive surgery at UCLA during the five-year period 1974 to 1979. Optimal cytoreduction (defined as largest residual tumor mass 1.5 cm or less in diameter) was achieved in 31 patients (66%), including ten of 14 (71%) who underwent laparotomy and biopsy before referral. Median survival for the suboptimal group was six months, compared with 18 months for patients whose largest residual disease was 0.5 to 1.5 cm, and 40 months if residual nodules were less than 0.5 cm (P less than .001). All patients in the suboptimal group died of disease from 22 months to seven years and four months postoperatively. Given the limited ability of chemotherapy to cure ovarian cancer, and the acceptable morbidity of extended operation, the availability of ideal initial surgical effort for patients with advanced stage disease may be the most important variable in current ovarian cancer care. Optimal cytoreduction is most effective in prolonging survival in patients first seen without clinical ascites or large metastatic disease.

Abstract
One hundred thirteen patients with invasive carcinoma of the vulva underwent radical vulvectomy and bilateral inguinal-femoral lymphadenectomy between 1957 and 1978. Eighteen had unilateral pelvic lymphadenectomy. Thirty-one patients (27.4%) had positive lymph nodes. The corrected actuarial five-year survival for patients with negative nodes was 96%, whereas it was 94% for patients with one positive node, 80% for those with two positive nodes, and 12% for those with three or more positive nodes. All patients with positive pelvic nodes or pelvic recurrence had three or more positive unilateral groin nodes, and all had palpably suspicious groin nodes preoperatively. Groin and systemic recurrences occurred in 2.9 and 3.8%, respectively, of patients with fewer than three positive unilateral inguinal-femoral nodes, as compared to 33 and 66%, respectively, of patients with three or more positive nodes. These data do not support routine pelvic lymphadenectomy in patients who have no clinically suspicious groin nodes and fewer than three positive nodes on histologic examination.

Abstract
Corynebacterium parvum has been administered i.p. to 14 patients with advanced ovarian cancer. Two patients had responded completely to cytoreductive surgery and combination chemotherapy prior to immunotherapy, and one patient with residual disease had received only a single course of C. parvum due to i.p. catheter malfunction. Among the 11 patients with residual disease evaluable for response, from three to eight i.p. treatments with C. parvum produced surgically confirmed tumor regression in five patients (45%) with three partial responses and two complete responses of 5 and 12 months duration. All responders had (a) multiple tumor nodules less than 0.5 cm at the initiation of immunotherapy, and (b) severe abdominal pain and fever after C. parvum injection. Overall, 58 courses of immunotherapy were associated with abdominal pain (91%), fever (67%), nausea (52%), vomiting (31%), and hypotension that responded promptly to i.v. infusion of fluids (10%). Use of i.p. cathethers was associated with two episodes each of infection and intraabdominal bleeding. Administration of C. parvum i.p. has augmented the ability of human peritoneal cells to lyse human ovarian carcinoma cell lines in the presence of specific rabbit heteroantiserum. C. parvum administered i.p. has inhibited the growth of human ovarian carcinoma and may prove useful for modulating the activity of human effectors for antibody-dependent cell-mediated cytotoxicity.

Abstract
Seven patients with superficially invasive vulvar cancer and lymph node metastases are reported. Histology of the primary tumor does not seem to correlate reliably with its metastatic potential in any individual case, though "spray," pseudoglandular, and small cell carcinomas may be particularly aggressive lesions. While wide local excision seems to be adequate treatment for the primary lesion, it is recommended that for lesions with greater than 1 mm of stromal invasion, bilateral inguinal-femoral lymphadenectomy should be performed for midline lesions, and at least ipsilateral inguinal-femoral lymphadenectomy should be performed for lateralized lesions.

Abstract
Cytoplasmic receptors for 17 beta-estradiol (ER) and progesterone (PR) were measured in uterine cervical, vaginal, and vulvar carcinomas by the dextran-coated charcoal (DCC) technique. Tissues from 30 patients with cervical carcinoma were examined. Thirteen percent (2 of 16) of well-differentiated squamous carcinomas had positive ER, and 19% (3 of 19) had positive PR. None of the three patients with moderately well-differentiated disease have positive ER or PR, while two of five patients with poorly differentiated lesions contained measurable ER and PR. In contrast, all four of the well-differentiated adenocarcinomas of the cervix had detectable ER, and three of four for PR. Neither of the two patients with poorly differentiated adenocarcinoma had either ER or PR. None of the five vulvar and seven vaginal epidermoid carcinomas studied had ER or PR activity. Hormonal therapies may be useful in the treatment of adenocarcinoma of the cervix.

Abstract
Improved surgical and chemotherapeutic management has ensured that more than half the patients with advanced ovarian cancer will be clinically free of disease shortly after treatment begins. Aggressive cytoreductive surgical treatment and combination cytotoxic chemotherapy have appreciably prolonged survival and have induced cures in some women with metastatic disease. An increasing number of women are being seen with small residual disease at second-look laparotomy, and intraperitoneal administration of chemotherapeutic and immunotherapeutic agents is being investigated for these patients. Specific immunotherapies, including monoclonal antibodies raised against patients' own tumor cells, are also being investigated. During the next five years we may see significant improvement in the cure rate for this disease.

Abstract
Fourteen cases of primary carcinoma of the Bartholin gland were treated between 1955 and 1980. Follow-up information was available on all patients. Ten patients have survived free of disease for 5 or more years. Three patients with positive inguinal lymph nodes have survived 5 years. Histological patterns and lymph node involvement are analyzed. The authors' data and a review of the literature support the concept that radical vulvectomy with bilateral inguinal-femoral lymphadenectomy is required for all histologic types of Bartholin gland carcinoma. Routine pelvic lymph node dissection is not necessary when the inguinal-femoral nodes are negative for metastases.
