Umbilical artery Doppler flow velocimetry in intrauterine growth restriction and its relation to perinatal outcome.

OBJECTIVE: The purpose of this retrospective analysis was to compare pregnancy outcomes in growth-restricted fetuses retaining normal umbilical artery Doppler flow and the outcomes of pregnancies with end-diastolic velocity either diminished or severely reduced/absent. METHODS: One hundred pregnant women with growth-restricted fetuses were followed with Doppler velocimetry of the umbilical artery between weeks 28 and 41 of pregnancy. Outcomes were compared for the normal Doppler group (16%), the less-severely abnormal group (77%), and the group with severely reduced or absent end-diastolic velocity waveforms (7%). RESULTS: The diagnosis-to-delivery interval was significantly shorter, and the average birth weight and gestational age at delivery were significantly lower, for fetuses with abnormal Doppler velocimetry (showing diminished or severely reduced/absent end-diastolic velocity) than for those in the normal Doppler group. Fetuses with abnormal Doppler velocimetry also had a significantly higher incidence of oligohydramnios, low-birth weight (<10th percentile), and admission to the Neonatal Intensive Care Unit. There were no perinatal deaths among the normal Doppler patients. CONCLUSIONS: Growth-restricted fetuses with normal umbilical artery velocimetry are at significantly lower risk than those with abnormal velocity waveforms, and immediate delivery of the fetus with diminished end-diastolic flow may be unnecessary. Knowing this relationship may be useful in the clinical management of such pregnancies. Doppler surveillance of growth-restricted fetuses supplemented with cardiotocography, preferably combined with biophysical profile testing, results in a prolonged gestational age and acceptable fetal outcome.

The prognostic significance of radiation dose and residual tumor in the treatment of barrel-shaped endophytic cervical carcinoma.

OBJECTIVE: The aim of this study was to evaluate the impact of total radiation dose on residual tumor and the prognostic significance of persistent disease in women with bulky, barrel-shaped cervical carcinoma who received definitive radiation followed by adjuvant hysterectomy. METHODS: The medical records of 57 patients with bulky endophytic cervical carcinoma treated at the University of Washington between 1976 and 1997 were reviewed. All patients received external beam pelvic radiotherapy supplemented by intracavitary brachytherapy, followed by extrafascial hysterectomy 6 to 8 weeks later. RESULTS: The mean pretreatment tumor diameter was 5.9 cm, with a range of 4-9 cm. Total radiation dose to point A ranged from 5040 to 9700 cGy, and the mean for the group was 7966 cGy. Residual disease was present in 35 (61%) of the hysterectomy specimens. The frequency of cervical tumor sterilization correlated significantly with the mean radiation dose to point A (P = 0.016). Patients without histologic residual disease had a significantly improved outcome, with 95% of patients remaining clinically free of disease at last follow-up, versus 31% of those with residual disease (P < 0.001). As expected, the pelvic control rate was excellent (100%) in patients with complete tumor eradication compared to the group with residual tumor (44%). Those with no residual disease enjoyed a significantly improved survival compared to those with residual tumor (P < 0.001). Furthermore, a statistically significant higher survival was realized in patients harboring only microscopic residual compared to those with either macroscopically evident tumor residuum and/or positive surgical margins (P = 0.036). CONCLUSIONS: Higher radiation doses are associated with an improved likelihood of tumor eradication in the treatment of bulky, endophytic cervical cancer and complete tumor sterilization at adjuvant hysterectomy is predictive of significantly enhanced survival and pelvic control. The high rate of histologic tumor persistence in our series emphasizes the need for more efficacious therapies in patients with bulky endophytic cervical cancer and argues for escalation of radiation dose even when adjuvant hysterectomy is planned.

Pretreatment scalene node biopsy in gynecologic malignancy: prudent or passé?

OBJECTIVES: Surgicopathologic evaluation of the scalene fat pad is considered a critical step in the pretreatment evaluation of patients at our institution with cervical or corpus carcinoma when the periaortic lymph nodes (PAN) are involved. However, enthusiasm for this procedure at other centers has waned, largely due to a wide discrepancy in the reported rates of occult scalene node involvement. In an attempt to clarify the benefit of pretreatment scalene node sampling in gynecologic malignancies, we present our experience over the past 18 years. MATERIALS AND METHODS: We identified 57 patients who underwent scalene node sampling between 1980 and 1998. In 39 of 49 (80%), the decision to proceed with scalene node sampling was based entirely on histologically documented PAN metastases. In the remainder, scalene node sampling was prompted by the presence of suspicious clinical findings. RESULTS: Of the 49 patients included in the study, 33 had carcinoma of the cervix, while 16 had corpus carcinoma. Ninety percent of scalene node sampling was performed at the time of primary diagnosis. Overall, 9 patients (18%) had scalene node metastases. Notably, not a single patient with corpus cancer was found to have scalene node metastases in the absence of clinically evident scalene node enlargement independent of PAN status. In cervix cancer cases, the presence of grossly involved PAN was predictive of a high likelihood of scalene node metastases (44%), while no patient with occult PAN metastases had involvement of the scalene node. Only 1 minor complication was encountered following scalene node sampling. The 40 scalene node-negative patients were treated with either extended field radiation or whole abdominal radiation therapy, and 20% developed a major, RTOG grade >/=3 complication such as fistula formation, bowel obstruction, or ureteral stenosis. Only 1 case of mild radiation enteritis and cellulitis occurred during palliative radiation in the group of patients with scalene node metastases. CONCLUSIONS: Scalene node sampling may be of benefit in the pretreatment evaluation of patients with cervical carcinoma when PAN are grossly involved. Given that scalene node involvement satisfies the criteria for distant metastases, identification of such allows the clinician to avoid the morbidity of extended field radiotherapy in a setting without the chance for cure.

Impact of surgical staging in women with locally advanced cervical cancer.

OBJECTIVE: The aim of this study was to evaluate the impact of surgical staging in the treatment and outcome of women with locally advanced cervical cancer. METHODS: Ninety-eight women with locally advanced cervical cancer treated between 1993 and 1997 were retrospectively reviewed. Survival probabilities were calculated by the Kaplan-Meier product limit method and compared with the log-rank test. RESULTS: Of the 98 women treated over the 5-year period, 86 were surgically staged: 61 by a retroperitoneal approach, 18 by laparoscopy, and 7 by laparotomy. Median blood loss was 120 cc and median length of hospitalization was 3 days. Preoperative CT scans (n = 55), when compared with surgical findings, missed macroscopic nodal disease in 20% and microscopic disease in 15% and overcalled disease in 10% of cases. Lymph node metastases were found in 45/86 patients (52%): 12 microscopic and 33 macroscopic. The highest level of nodes found to be involved was pelvic in 23, common iliac nodes in 3, para-aortic nodes in 14, and scalene nodes in 5 cases. Of the 86 patients, 49 received pelvic radiation, 27 received extended field radiation, and 10 were identified for palliative treatment only (5 scalene node metastasis, 5 extensive intraperitoneal disease). For node-negative patients, 5-year survival was 74%; for microscopic nodal involvement it was 58%; and for macroscopic involvement it was 39% (P = 0.007). Five-year survival for women with para-aortic node involvement was 52%. Number of nodes involved was a significant prognostic variable (P = 0.008). Patients who received chemotherapy had a 5-year survival of 68% compared to 35% for those who did not (P = 0.06). Factors which did not affect survival included age, histology, type of surgery, stage, and type of radiation (pelvic vs extended). CONCLUSION: Surgical staging of women with locally advanced cervical cancer can be performed with acceptable morbidity and it provided more accurate information than CT scans and resulted in a modification of the standard pelvic radiation field for 43% of our patients. The information obtained from surgical staging allows better individualization of therapy, which may improve overall clinical outcome.

A new technique for performing Syed template interstitial implants for anterior vaginal tumors using an open retropubic approach.

The Syed template (Alpha-Omega Services, Bellflower, CA) has been established as an advance in interstitial gynecologic brachytherapy. Unfortunately, enthusiasm for the technique is often tempered by certain tumor geometries which require blind insertion of the interstitial needles, potentially risking inaccurate placement of the radioactive sources and viscus perforation. These concerns arise particularly in the management of anterior vaginal tumors where difficulties in negotiating the pubic arch can prevent optimal needle placement. In answer to this problem, a technique utilizing an open retropubic approach for Syed template interstitial implants in anterior vaginal tumors under direct visualization is described. To date, six procedures have been performed. The disease entities include advanced cervical squamous cell carcinoma, clear cell carcinoma of the vagina, recurrent vaginal carcinoma, recurrent endometrial carcinoma, and urethral adenocarcinoma. Complete response was noted in five of six patients but persistent local control of disease was achieved in only one of five complete responses over a relatively short follow-up interval. Complications included paravaginal abscess (n = 1), postoperative deep venous thrombosis (n = 1), abdominal incision cellulitis (n = 1), and radiation enteritis (n = 1). An open retropubic approach allows direct visualization of the bladder and urethra during interstitial implantation of anterior vaginal malignancies and facilitates negotiation of the pubic arch. In our experience, this technique results in improved needle positioning and is thus intuitively likely to aid in avoiding injury to surrounding normal tissues. Additional accrual of a larger cohort will be necessary to arrive at any meaningful objective conclusions regarding the technique's benefit over current modalities.

Oncogene expression: long-term compared with short-term survival in patients with advanced epithelial ovarian cancer.

OBJECTIVE: To determine if oncogene overexpression in patients with advanced epithelial ovarian cancer correlates with survival. METHODS: Twenty-two women with stage III ovarian cancer, observed for a median of 66 (range 48-204) months were compared with 30 with a median survival of 18 (range 2-28) months. Using immunocytochemistry, tumors were immunostained for overexpression of p53, c-erb-B-2, and epidermal growth factor receptor and were evaluated quantitatively for expression of estrogen receptor, progesterone receptor, and Ki-67 antigen, a marker of cellular proliferation. RESULTS: The median age of long-term survivors was 52 (range 30-76) years compared with 55 (range 36-80) years for short-term survivors. Optimal cytoreduction was achieved in 11 of the 22 long-term survivors compared with seven of the 30 short-term survivors, a significant difference (P=.05). The average level of Ki-67 expression was 43% in long-term survivors and 64% in short-term survivors (P=.007). Overexpression of p53 was seen in 54% of long-term survivors and 80% of short-term survivors (P=.05). A combination of Ki-67 level of 50% or greater plus p53 overexpression was seen in 22% of long-term survivors compared with 68% of short-term survivors (P=.005). Epidermal growth factor receptor, c-erb-B-2, estrogen receptor, and progesterone receptor statuses did not differ significantly between the two groups. CONCLUSION: Markers that did not correlate with survival included the hormone receptors, estrogen receptor and progesterone receptor, and the oncogenes, c-erb-B-2 and epidermal growth factor receptor. Long-term survivors with advanced ovarian cancer were more likely to have had an optimal cytoreduction and lower levels of Ki-67 antigen expression and were less likely to overexpress p53 than were short-term survivors.

Adenocarcinoma of the uterine cervix metastatic to lymph nodes.

OBJECTIVE: We set out to evaluate the prognostic factors in cervical adenocarcinoma metastatic to lymph nodes. STUDY DESIGN: We performed a retrospective review of 40 patients with cervical adenocarcinoma and lymph node metastasis from 1976 to 1996. RESULTS: Thirty-four patients had adenocarcinoma, and six had adenosquamous carcinoma. Median survival was 50 months. The median survival for patients with stage I disease was 69 months. Stage at diagnosis, treatment with radical hysterectomy, and receiving adjuvant therapy were associated with prolonged survival. A trend toward improved survival was noted with the use of concurrent radiation and chemotherapy as an adjuvant therapy. CONCLUSIONS: Adenocarcinoma metastatic to the lymph nodes does not have a uniformly poor prognosis, especially with early-stage disease. Improved survival was observed with the use of adjuvant therapy, specifically the use of combined chemotherapy and radiation after radical hysterectomy. The optimal therapy in this setting is yet to be determined.

Serum inhibin and disease status in women with ovarian granulosa cell tumors.

OBJECTIVE: To determine if immunoreactive inhibin assayed in serum from women with granulosa cell tumors correlated with tumor burden, reflected response to treatment, or predicted recurrent disease. STUDY DESIGN: Serum samples were collected following bilateral oophorectomy (BSO) with or without other indicated surgery in 15 patients with granulosa cell tumors. Inhibin radioimmunoassay (RIA-Inh) was performed on all samples and results were correlated with tumor burden, disease status, and treatment response. RESULTS: Fifteen patients had serum assayed for inhibin with levels ranging from 0 to 7470 U/liter. In 4 patients with measurable recurrent disease, inhibin levels correlated directly with tumor burden (r2 = 0.96). Four patients had serum drawn during clinical remission and in all 4 patients elevated inhibin levels predated recurrence by a median interval of 11.5 months (range 7-20). The remaining 7 were treated for primary disease and were in clinical remission with a median follow-up of 33 months (range 9-53). Four of these 7 patients were surgically staged: 2 were FIGO Stage I and inhibin levels fell to 0 U/liter; 2 patients had metastatic disease (Stage IIc and IIIa) and their inhibin levels were found to be elevated following complete resection. The remaining 3 were not surgically staged, and all had elevated inhibin levels while in clinical remission, suggesting occult disease. Of the 15 total patients, 1 who was treated with chemotherapy for recurrent disease was followed with serial inhibin levels. She showed a complete response to therapy with inhibin levels falling from 975 to 0 U/liter with 15 months follow-up. CONCLUSIONS: Serum inhibin levels reflect tumor burden and may be valuable in assessing response to chemotherapy or predicting recurrent disease in women with granulosa cell tumors who have had BSO. Serum inhibin level evaluation should be incorporated into large-group trials of therapy for granulosa cell tumors.

Phase II study of high-dose cisplatin, etoposide, and cyclophosphamide for refractory ovarian cancer.

OBJECTIVES: A phase II trial of high-dose cyclophosphamide, etoposide, and cisplatin was done. STUDY DESIGN: Forty-eight patients with progressive or persistent disease and previous cisplatin-based chemotherapy and no paclitaxel therapy were entered for treatment on the basis of two cycles of cyclophosphamide (4500 mg/m2), etoposide (750 mg/m2), and cisplatin (120 mg/m2). RESULT: Seventy-four cycles were delivered. Six patients died during treatment (12.5%). Of 28 with measurable disease, there was a 25% response rate and 32% had stable disease. Median time to recurrence and survival were significantly different for minimal versus bulky disease (p = 0.0089, p = 0.0008, log rank) and for platinum-sensitive versus platinum-resistant disease (p = 0.18, p = 0.0012, log-rank). The number of prior regimens was not correlated with time to progression or survival. CONCLUSION: This study shows little advantage for high-dose protocols except for patients with a response to platinating agents and minimal residual disease.

Clear cell carcinoma of the ovary: a distinct histologic type with poor prognosis and resistance to platinum-based chemotherapy in stage III disease.

Between 1982 and 1992, 24 women with Stage III clear cell ovarian cancer were identified from the tumor registry. Thirty-four women with Stage III papillary serous tumors treated between 1987 and 1989 were used as a comparison. All patients underwent cytoreductive surgery followed by conventional platinum-based chemotherapy. In the women with clear cell histology, nine (37.5%) had endometriosis in the surgical specimen compared with one (3%) in the papillary serous group (P = 0.002). Ten women (42%) with clear cell histology experienced a thromboembolic event during the course of treatment, compared to six (18%) in the papillary serous group (P = 0.05). In the group with clear cell histology, overall, 70% of women had progressive disease. Fifty-two percent experienced clinical progression while receiving platinum-based chemotherapy. In addition, four patients were found to have progressive disease at second-look laparotomy. Only two patients had a pathologic complete response. In the group with papillary serous histology, 29% overall had progressive disease while on chemotherapy (P = 0.005). The median survival for the women with clear cell histology was 12 months compared to 22 months for those with papillary serous (P = 0.02). For women with clear cell histology, univariate analysis was used to evaluate prognostic factors. Age less than 50 was a poor prognostic factor (P = 0.045). The presence of endometriosis, thromboembolic event, or optimal cytoreduction were not prognostic factors (P = 0.67, P = 0.34, P = 0.39). Patients with advanced clear cell ovarian cancer have a poor response to conventional platinum-based chemotherapy and overall prognosis is poor.

The expression of epidermal growth factor receptor, HER-2/Neu, p53, and Ki-67 antigen in uterine malignant mixed mesodermal tumors and adenosarcoma.

Uterine malignant mixed mesodermal tumors (MMMT) are highly malignant tumors containing both malignant glands and stroma, while adenosarcomas (AS) are less aggressive tumors composed of malignant stroma and benign glands. Immunohistochemistry was used to grade overexpression of p53 protein, HER-2/neu protein, epidermal growth factor receptor (EGFR), and Ki-67 antigen in both the glands and stroma of tissue from 20 women with MMMT and 6 women with AS. EGFR was overexpressed in 2 AS and 9 MMMT, and was more commonly found in the sarcomatous component than the carcinomatous component in MMMT (P = 0.03). p53 was not found in any AS samples and was strongly present in 6 MMMT samples with a random distribution between the malignant components. HER-2/neu protein was not overexpressed in any AS or primary MMMT. Ki-67 antigen, a marker of cell proliferation, was found at higher levels in MMMT than AS samples (P = 0.03) and high Ki-67 antigen expression correlated with a decreased survival in patients with MMMT (P = 0.004). Independent characterization of oncogene proteins in the malignant components of these heterogeneous tumors may provide insight into the histogenesis and behavior of these malignancies.

The use of intraoperative radiation therapy in radical salvage for recurrent cervical cancer: outcome and toxicity.

OBJECTIVE: Our purpose was to evaluate the contribution of intraoperative radiation therapy in the management of recurrent cervical cancer. STUDY DESIGN: Twenty-two patients were treated with electron beam intraoperative radiation therapy for recurrent cervical cancers that were confined to the pelvis but were too extensive to be adequately treated by radical surgery alone. All patients underwent extensive surgical dissection for exposure and maximal tumor resection. Doses of intraoperative radiation therapy ranged from 14 to 27.8 Gy (median 22 Gy). Twelve patients received intraoperative radiation therapy to address gross residual disease, and 10 patients were treated for microscopically positive or close surgical margins. RESULTS: The five-year disease-specific survival and local control rates were 43% and 48%, respectively. There were trends toward better local control and disease-specific survival in patients with microscopic residual disease compared with those with gross residual disease. Seven patients had peripheral neuropathy related to treatment, and four of these cases resolved. CONCLUSION: In carefully selected cases intraoperative radiation therapy contributes to radical salvage of patients with recurrent cervical cancer involving the pelvic wall.

Chemoprevention of cervical cancer with folic acid: a phase III Southwest Oncology Group Intergroup study.

Several epidemiological reports and experimental investigations have suggested a preventive role for folic acid in the etiology of cervical cancer. The effect of p.o. folic acid supplementation on the natural history of cervical intraepithelial neoplasia (CIN) was evaluated in a multiinstitutional prospective, randomized, double-blind, placebo-controlled trial. Three hundred thirty-one women with biopsy-proven koilocytic atypia, mild CIN, or moderate CIN were randomized to receive oral folic acid (5 mg) or a similar-appearing placebo daily for 6 months following a 1-month run-in placebo period. Colposcopy, Papanicolaou smear, and serum vitamin levels (folate, retinol, alpha-tocopherol, beta-carotene, and retinyl palmitate) were monitored every 3 months. Demographic, medical, dietary, and sexual history data were obtained from personal interviews. The primary end point of the study was improvement in both Papanicolaou smear and colposcopic picture after 3 and 6 months of treatment as compared to the start of treatment. After 6 months of treatment there was no significant difference between the two study groups in the percentage of patients improved. Median serum folate levels in the treatment arm at 3 and 6 months (29.0 and 20.0 micrograms/dl) were significantly higher than those in the placebo arm (7.8 and 7.1 micrograms/dl, respectively). Mean serum levels of retinol, retinyl palmitate, alpha-tocopherol, and beta-carotene did not differ significantly between the two treatment arms. Our data support the conclusion that supplementation with folic acid (5 mg/day) does not enhance the regression of early epithelial abnormalities of the cervix.(ABSTRACT TRUNCATED AT 250 WORDS)

Primary central nervous system recurrence after paclitaxel therapy for epithelial ovarian malignancy.

Paclitaxel is currently being utilized to treat neoplasms which have a significant incidence of central nervous system metastases. It is, however, unclear as to whether paclitaxel crosses the blood-brain barrier. In this report, the authors describe a patient with refractory epithelial ovarian cancer treated with paclitaxel at 135 mg/m2/24 hr every 21 days. The patient achieved a complete clinical response of all abdominal and pelvic disease, but simultaneously developed central nervous system metastases. Paclitaxel was effective against the patient's abdominal and pelvic disease but was not protective against central nervous system metastasis.

Uterine papillary serous carcinoma: patterns of metastatic spread.

Uterine papillary serous carcinoma (UPSC) is a distinct histologic type of endometrial cancer which is associated with a high relapse rate and poor prognosis. Between 1983 and 1993, 50 patients with UPSC of the endometrium were surgically staged. Thirty-three patients had pure UPSC and 17 had UPSC admixed with other histologies. Extrauterine disease was found in 36 women (72%). Lymph node metastases were present in 36% of women without myometrial invasion, 50% with inner one-half invasion, and 40% with outer one-half invasion. Similarly, the presence of intraperitoneal disease or positive washings did not correlate with increasing myometrial invasion. Grade and histology (mixed vs pure) were also not predictive of extrauterine disease. Patients with lymphatic/vascular space invasion (LVSI) were more likely to have extrauterine disease (85%); however, even without LVSI the incidence of extrauterine disease was 58% (P = 0.05). Unlike endometrioid adenocarcinomas, grade and depth of myometrial invasion were not significant predictors for extrauterine disease. This study reinforces the need for complete surgical staging in all patients with UPSC regardless of depth of invasion.

Expression of c-erb B-2 oncogene product in persistent gestational trophoblastic disease.

OBJECTIVE: Much debate exists on the initiation of chemotherapy for women at risk for persistent gestational trophoblastic disease. This is a result of a lack of early predictors for the development of persistent gestational trophoblastic disease after evacuation of a complete hydatidiform mole, because the only current reliable method of detection and diagnosis lies in persistent or rising postmolar beta-human chorionic gonadotropin values. We used immunocytochemical techniques to retrospectively study the expression of the c-erb B-2 oncogene product in formalin-fixed, paraffin-embedded trophoblastic tissues as a potential indicator of the development of persistent gestational trophoblastic disease. STUDY DESIGN: In this retrospective study 56 trophoblastic tumors were examined by means of immunocytochemical techniques to stain for the oncogene product for evidence of c-erb B-2 expression. Our 56 cases included original tissue from 20 cases of complete mole that progressed to persistent gestational trophoblastic disease, seven cases of choriocarcinoma after term pregnancy or abortion, and 29 cases of hydatidiform mole representing postevacuation, spontaneously regressing disease (including one partial mole). We also studied 11 cases of first-trimester trophoblast and 15 cases of term placenta as additional controls. RESULTS: Our results showed positive immunostaining for c-erb B-2 gene product in one case of persistent gestational trophoblastic disease, with negative staining in all other cases in the study groups and controls. CONCLUSION: Analysis for the significance of c-erb B-2 expression in persistent gestational trophoblastic disease showed that this correlation between c-erb B-2 expression and persistent gestational trophoblastic disease is not significant, suggesting that future efforts should be directed at the involvement of different oncoproteins.

Paclitaxel (Taxol) treatment for refractory ovarian cancer: phase II clinical trial.

OBJECTIVE: Our aim was to determine the efficacy and toxicity of paclitaxel in the treatment of refractory and platinum-resistant epithelial ovarian cancer. STUDY DESIGN: Eligibility required three prior failed chemotherapy regimens and documented platinum resistance. One hundred patients with advanced ovarian cancer received paclitaxel 135 mg/m2 over 24 hours every 21 days with optional granulocyte colony-stimulating factor support. RESULTS: Paclitaxel was generally well tolerated. In four patients bowel perforation or fistula developed. After three cycles 34% of patients had stable disease and 25% of patients demonstrated a response, either partial or complete. After six cycles 24% of patients continued to respond. To date, six patients have achieved a complete response. CONCLUSION: A 25% response rate in patients with refractory ovarian cancer was observed, which was durable to six cycles.

Combined radiotherapy and chemotherapy in the management of local-regionally advanced vulvar cancer.

PURPOSE: To determine, in a retrospective single institutional study, the role of concurrent radiotherapy and chemotherapy in the treatment of local-regionally advanced vulvar cancer. METHODS AND MATERIALS: From 1984 to 1991, 20 patients with locally extensive primary or recurrent carcinoma of the vulva were treated with initial combined radiotherapy and chemotherapy. Seven patients had Federation Internationale de Gynecologie et d'Obstretrique Stage III disease, 10 had Stage IV disease, and three were treated for recurrent disease. None of these patients were considered candidates for primary radical vulvectomy and groin node dissection. Median radiation doses to regions of microscopic disease and gross tumor were 40 Gy (range 30-54 Gy) and 54 Gy (34-70.4 Gy), respectively. All patients received 2 or 3 cycles of 5-Fluorouracil concurrently with radiotherapy. In addition, five patients received Cis-platinum, and one Mitomycin-C. Median at-risk follow-up interval was 37 months. RESULTS: Ten patients had complete resolution of tumor to initial chemoradiotherapy, and eight of these have remained free of tumor relapse. Eight other patients had partial responses, with tumor bulk reduced by > 50%, while the remaining two patients had local-regionally progressive disease. Six of the patients with partial responses had residual tumor successfully resected, although four subsequently recurred. For the entire group of 20 patients, the actuarial 3- and 5-year local control rates were 48% each, and the corresponding disease-specific survival rates were 59% and 49%. There was a suggestion that better local control was obtained in patients who received gross tumor radiation doses > or = 50 Gy. Skin reaction was the major acute toxicity and responded well to conservative management. Long-term sequalae were limited to skin and subcutaneous atrophy. CONCLUSION: These results indicate that initial combined radiotherapy and chemotherapy is effective in the management of advanced vulvar cancer.
