Endometrial carcinoma recurrence according to race and ethnicity: An NRG Oncology/Gynecologic Oncology Group 210 Study.

Non-Hispanic black (NHB) women are more likely to experience an endometrial carcinoma (EC) recurrence compared to non-Hispanic white (NHW) women. The extent to which tumor characteristics, socioeconomic status (SES) and treatment contribute to this observation is not well defined. In the NRG Oncology/Gynecology Oncology Group (GOG) 210 Study we evaluated associations between race/ethnicity and EC recurrence according to tumor characteristics with adjustment for potential confounders. Our analysis included 3,199 NHW, 532 NHB and 232 Hispanic women with EC. Recurrence was documented during follow-up. We used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between race/ethnicity and EC recurrence in models stratified by histologic subtype (low-grade endometrioid, high-grade endometrioid, serous, mixed cell, carcinosarcoma, clear cell) or stage (I, II, III) and adjusted for age, SES, body mass index, smoking status and treatment. In histologic subtype-stratified models, higher EC recurrence was noted in NHB women with low-grade endometrioid (HR = 1.94, 95% CI = 1.21-3.10) or carcinosarcomas (HR = 1.66, 95% CI = 0.99-2.79) compared to NHWs. In stage-stratified models, higher EC recurrence was noted among NHB women with stage I (HR = 1.48, 95% CI = 1.06-2.05) and Hispanic women with stage III disease (HR = 1.81, 95% CI = 1.11-2.95). Our observations of higher EC recurrence risk among NHB and Hispanic women, as compared to NHW women, were not explained by tumor characteristics, SES, treatment or other confounders. Other factors, such as racial differences in tumor biology or other patient factors, should be explored as contributors to racial disparities in EC recurrence.

Phase II multicenter open-label study of karenitecin in previously treated epithelial ovarian and primary peritoneal cancer: a Gynecologic Oncology Group Study.

The topoisomerase I agents are established as a therapy in recurrent ovarian cancer. Karenitecin, an analog of topotecan with solubility and pharmacologic advantages, was tested in a phase II trial in previously treated patients with recurrent or persistent ovarian cancer. The drug was administered intravenously over 1 h at a dose of 1.0 mg/m(2) daily for 5 days every 21 days. Patients were treated until disease progression, intolerable toxicity, or voluntary withdrawal. Response was evaluated according to modified RECIST criteria. Twenty-seven patients were entered into the study. One patient was inevaluable for not receiving any treatment. Of the 26 evaluable patients, there were two partial responses and one complete response for a total response rate of 12%. This response rate was insufficient to justify accrual to the second stage. The most common grade 3 or 4 toxicities were neutropenia (19%) and gastrointestinal (15%). Karenitecin is a well-tolerated topoisomerase compound but has minimal activity in extensively pretreated ovarian cancer with the dose-schedule employed.

cAMP and PMA enhance the effects of IGF-I in the proliferation of endometrial adenocarcinoma cell line HEC-1-A by acting at the G1 phase of the cell cycle.

The present study was undertaken to determine whether endometrial cancer cell line HEC-1-A differ from nontransformed cells, in that the cAMP and protein kinase C pathways may enhance IGF-I effects in mitogenesis by acting at the G1 phase of the cell cycle instead of G0. Immunofluorescence staining of HEC-1-A cells using the proliferating cell nuclear antigen (PCNA) monoclonal antibody and flow cytometric analysis determined that HEC-1-A cells do not enter the G0 phase of the cell cycle when incubated in a serum-free medium. Approximately 51% of the cells were in G1, 12% were in S and 37% in G2 phase of the cell cycle prior to treatment. Forskolin and phorbol-12-myristate 13-acetate (PMA) were used to stimulate cAMP production and protein kinase C activity, respectively. IGF-I, forskolin and PMA each increased (P < 0.01) [3H]-thymidine incorporation in a dose and time dependent manner. The interaction of forskolin and PMA with IGF-I was then determined. Cells preincubated with forskolin or PMA followed by incubation with IFG-I incorporated significantly more (P < 0.01) [3H]-thymidine into DNA than controls or any treatment alone. It is concluded that forskolin and, to a lesser extent, PMA exert their effect at the G1 phase of the cycle to enhance IGF-I effects in cell proliferation.

Percutaneous transcatheter embolization for control of life-threatening pelvic hemorrhage from gestational trophoblastic disease.

Pelvic hemorrhage from gestational trophoblastic disease remains a common and vexing problem. Traditional surgical therapy, including hysterectomy and hypogastric artery ligation, may be technically difficult as well as hazardous to debilitated patients. In contrast, percutaneous transcatheter embolization specifically occludes the vessels that directly contribute to bleeding. Other potential advantages include avoidance of general anesthesia and major surgery, a rapid recovery period, and preservation of fertility. Various embolic materials allow one to tailor the duration of occlusion to the underlying disorder. Reported complications are rare and generally involve aberrant emboli or inadequate collateral circulation leading to ischemic injury. We believe that transcatheter embolization should be considered an alternative to operative intervention for control of pelvic hemorrhage from gestational trophoblastic disease.

Ovarian lipoma of teratomatous origin.

BACKGROUND: Lipomatous tumors of ovarian origin are rare and may arise from overgrowth of metaplastic fat cells in the stroma. CASE: A 5-cm, circumscribed, grossly yellow tumor was an incidental finding at the time of hysterectomy for endometrial cancer. The ovarian tumor was composed almost exclusively of benign adipocytes. Small collections of benign sweat glands were present at the periphery of the tumor. CONCLUSION: This predominantly lipomatous ovarian tumor likely represents a fat-rich solid teratoma.

A randomized controlled trial of postoperative nasogastric tube decompression in gynecologic oncology patients undergoing intra-abdominal surgery.

OBJECTIVE: To evaluate the effect of nasogastric decompression after extensive intra-abdominal surgery in gynecologic oncology patients. METHODS: Over a 1-year period, 110 gynecologic oncology patients undergoing extensive intra-abdominal surgery were enrolled in a randomized controlled trial of postoperative nasogastric tube versus intra-operative orogastric tube decompression. RESULTS: The nasogastric and orogastric groups were similar in age, case distribution, surgery length, and blood loss. The nasogastric group had significantly longer times to first passage of flatus and tolerance of a clear liquid diet than did the orogastric group. However, both groups were similar in time to tolerance of a regular diet and hospital stay. On average, the nasogastric tube was maintained for 3.2 +/- 2.1 days (range 1-8) after surgery. The average daily nasogastric output was 440 +/- 283 mL (range 68-1565). No patient in the orogastric group required a nasogastric tube postoperatively, but one patient in the nasogastric group had a nasogastric tube reinserted for recurrent nausea and vomiting. Use of a nasogastric tube led to significantly more subjective complaints, eg, ear pain, painful swallowing, and nasal soreness, but did not significantly reduce the incidence of abdominal distention or nausea and vomiting. Major complications, eg, pneumonia, atelectasis, gastrointestinal bleeding, and wound breakdown or infection, occurred equally in both groups. However, the incidence of febrile morbidity was significantly greater in the nasogastric group. There were no known anastamotic complications or aspirations in either group. Postoperative changes in hematological indices and electrolytes were comparable in both groups. CONCLUSION: Postoperative nasogastric tube decompression in gynecologic oncology patients undergoing extensive intra-abdominal surgery does not appear to provide any substantial benefit but significantly increases patient discomfort. As a result of this study, we have eliminated postoperative nasogastric decompression except in highly selected circumstances, such as extensive bowel surgery in patients with prior irradiation or substantial edema from bowel obstruction.

Incontinence following rupture of the anal sphincter during delivery.

OBJECTIVE: To determine the frequency with which patients report incontinence of flatus or stool after rupture of the anal sphincter during delivery. METHODS: A chart review and telephone interview were conducted with 70 primiparas, 35 of whom had rupture of the anal sphincter at delivery and 35 of whom did not. All were contacted 9-12 months postpartum and questioned about the development of incontinence of gas or liquid or formed stool, persistent dyspareunia, and perineal pain. RESULTS: Incontinence of gas was reported by six women (17%) in the rupture group and one (3%) in the control group (P < .05). The incidence of incontinence of stool, both liquid and solid, dyspareunia, and persistent perineal pain were similar between the groups. CONCLUSION: Incontinence of flatus was reported six times more often by women who experienced a third- or fourth-degree perineal laceration than by those without anal sphincter rupture.

The relationship of the umbilicus to the aortic bifurcation: implications for laparoscopic technique.

OBJECTIVE: We evaluated the location of the umbilicus relative to the aortic bifurcation and the left common iliac vein where it crosses the midline. METHODS: Abdominal computed tomography images from 35 reproductive-age women were retrospectively reviewed to determine the location of the umbilicus. The results were correlated with body mass index using Pearson correlation coefficient and a two-tailed paired t test. RESULTS: The location of the umbilicus, but not the aortic bifurcation, was more caudal in heavier women and negatively correlated with body mass index. In nonobese women, the mean location of the umbilicus was 0.4 cm caudal to the aortic bifurcation, and was at or cephalad to the bifurcation in eight of 15 (53%). In overweight women, the mean umbilical location was 2.4 cm caudal to the bifurcation, and in obese women, 2.9 cm caudal to the bifurcation. In the last two groups of subjects, the umbilicus was located at the level of the bifurcation in six of 20 (30%). In every case, the umbilicus was located cephalad to where the common iliac vein crossed the midline. CONCLUSIONS: The umbilicus is often located at or cephalad to the aortic bifurcation, and consistently located cephalad to where the left common iliac vein crosses the midline. The laparoscopic approach should take these relationships into account to minimize injuries to major retroperitoneal vessels.

A randomized controlled trial of early postoperative feeding in gynecologic oncology patients undergoing intra-abdominal surgery.

OBJECTIVE: To evaluate the safety and efficacy of early oral feeding after intra-abdominal surgery in gynecologic oncology patients. METHODS: During a 1-year period, 200 gynecologic oncology patients undergoing intra-abdominal surgery were enrolled in a randomized controlled trial of early compared with traditional oral postoperative feeding. Patients allocated to early postoperative oral feeding began a clear liquid diet on the first postoperative day and then advanced to a regular diet as tolerated. Patients allocated to traditional postoperative oral feeding received nothing by mouth until return of bowel function (defined as the passage of flatus in the absence of vomiting or abdominal distention), then began a clear liquid diet, and advanced to a regular diet as tolerated. RESULTS: Age, case distribution, surgery length, blood loss, and first passage of flatus were similar in the early and traditional feeding groups. Significantly more patients in the early group developed nausea. Despite this, the incidence of vomiting, abdominal distention, incidence and duration of nasogastric tube use, and percentage of patients who tolerated clear liquid and regular diets on the first attempt were comparable in both groups. Time to development of bowel sounds, time to initiation of clear liquid and regular diets, and hospital stay were significantly longer in the traditional group. Major complications (eg, pneumonia, atelectasis, and wound complications) and febrile morbidity occurred equally in both groups. There were no known anastamotic complications or aspirations in either group. Postoperative changes in hematologic indices and electrolytes were comparable in both groups. CONCLUSION: Early postoperative feeding in gynecologic oncology patients undergoing intra-abdominal surgery is safe and well tolerated.

Laparoscopic injury of abdominal wall blood vessels: a report of three cases.

BACKGROUND: Operative laparoscopy is being used for an increasing number of applications. Many of these innovative techniques require the insertion of large trocars through the anterior abdominal wall at points lateral to the midline. Because of the rich vascular supply of the anterior abdominal wall, the incidence of abdominal wall vessel injuries appears to be increased by these techniques. CASES: Three cases are reported in which abdominal wall blood vessels were injured during operative laparoscopy. Case 1 describes laceration of the inferior epigastric artery above the pubic crest. Despite initial hemostasis with a transabdominal suture ligation, postoperative blood loss necessitated transfusion and reoperation to control bleeding. Case 2 describes hematoma formation after unrecognized injury to one of the epigastric vessels. The hematoma resolved without sequelae with conservative treatment. Case 3 describes hematoma formation under a laparoscopic trocar incision lateral to the umbilicus that progressed to an abscess and was treated with drainage, irrigation, and antibiotics. CONCLUSIONS: Choosing appropriate trocar types and insertion sites based on a thorough understanding of anterior abdominal wall anatomy may minimize the risk of vessel injury during operative laparoscopy. However, because of anatomical variation, strategies for managing vessel injuries and their sequelae are also necessary.

Panniculectomy and supraumbilical vertical midline incisions in morbidly obese gynecologic oncology patients.

BACKGROUND: We reviewed the outcomes of panniculectomy and supraumbilical vertical midline incisions in morbidly obese women undergoing gynecologic operations. STUDY DESIGN: Medical records were reviewed for 62 morbidly obese women with a large dependent pannus who underwent gynecologic operations on the Gynecologic Oncology Service at the State University of New York at Stony Brook between May 1990 and July 1997. Thirty-five patients underwent panniculectomy and 27 had a supraumbilical vertical midline incision, forming the study groups. The patient charts were abstracted for demographic, perioperative, and postoperative data. RESULTS: For the entire study population, the average age was 56 years, the mean body mass was 128.6 kg, and the mean Quetelet Index was 48.3 kg/m2. The mean operative time and estimated blood loss were similar for both groups. Eight percent of the patients had urologic injuries, evenly distributed between the groups. Postoperative infections, wound breakdowns, and hospital stay were greater for the panniculectomy group than for the supraumbilical vertical midline incision group (p < 0.05). Uniform use of subcutaneous closed-suction drains (since 1995) was associated with a significant reduction in the incidence of wound breakdowns and a shorter hospital stay in the panniculectomy group. CONCLUSIONS: Panniculectomy and supraumbilical vertical midline incision provide reasonable peritoneal access with acceptable rates of postoperative complications for morbidly obese women undergoing gynecologic operations.

Glenoid deformity secondary to brachial plexus birth palsy.

The association between internal rotation contracture secondary to brachial plexus birth palsy and deformity and posterior dislocation of the glenohumeral joint has been known for a long time. The precise nature of these deformities and their pathogenesis, however, remain unclear. Twenty-five children, ranging in age from 1.5 to 13.5 years, had an operation to release an internal rotation contracture secondary to brachial plexus birth palsy; eleven had a latissimus dorsi transfer to augment external rotation power as well. Arthrograms were made intraoperatively in order to clarify the pathological changes that occur in the glenohumeral joint during growth in patients who have this condition. Seven children had a concentric glenohumeral joint (the humeral head was well centered in the glenoid fossa). The remaining eighteen children (72 per cent) had a deformity of the posterior aspect of the glenoid. Five of these children had flattening of the posterior aspect of the glenoid, seven had a biconcave glenoid with the humeral head articulating with the posterior of the two concavities, and six had a so-called pseudoglenoid (the most severe deformity, in which the humeral head articulated with a distinct, retroverted, posterior articular surface). Internal rotation contracture secondary to brachial plexus birth palsy may lead to glenoid deformity that is severely advanced by the time that the child is two years old. In patients who have such a contracture, we recommend early imaging of the shoulder with arthrography or some other modality to allow visualization of the skeletally immature glenohumeral joint.

Geometric analysis of commonly used prosthetic systems for proximal humeral replacement.

BACKGROUND: The anatomy of the proximal part of the humerus is extremely variable. The extent to which existing prosthetic systems and operative technique allow replication of this variability has not been established. METHODS: Four commonly used press-fit prosthetic systems for shoulder arthroplasty were compared with respect to their ability to match the superior-inferior and medial-lateral dimensions of the articular surface in twenty-one cadaveric humeri. The comparisons were accomplished with a computer optimization algorithm that searched a database of prosthetic geometry and selected the best match to the original anatomy. The algorithm assumed an osteotomy of the humeral head at an angle equivalent to the stem-head angle of the prosthesis, without violation of the greater tuberosity or the metaphyseal bone. The best match was defined as the prosthetic combination (stem and head) that least displaced the center of rotation and the articular surface, with both factors weighted equally. RESULTS: None of the prosthetic systems that were evaluated allowed identical replication of the articular surface. Rather, they displaced the center of rotation a mean of 14.7 millimeters (range, 3.3 to 31.4 millimeters) from its original position. To reach this minimized displacement, the prosthetic combinations that were selected by the algorithm also resulted in a mean diminution of the arc of the articular surface (a smaller head size) of 26 degrees (range, 11 to 41 degrees). In every instance, the selected prosthesis imposed a superior and lateral shift of the center of rotation that in effect shifted a smaller prosthetic humeral head up the slope of the humeral osteotomy. CONCLUSIONS: Press-fit prosthetic systems for shoulder arthroplasty that are commonly used necessitate marked alterations of the original anatomy. To the extent that a shoulder arthroplasty is an attempt to reproduce the normal anatomy, these findings have profound implications for operative technique and future prosthetic design. CLINICAL RELEVANCE: We believe that the superior position of the prosthetic head predicted by the present study plays a role in late complications of shoulder arthroplasty, such as rotator cuff tendinopathy, superior humeral migration, and loosening of the glenoid component.

Predicting drug interactions in vivo from experiments in vitro. Human studies with paclitaxel and ketoconazole.

This study was performed to evaluate whether concomitant treatment with ketoconazole could reduce the clearance of paclitaxel given to ovarian cancer patients. Paclitaxel, 175 mg/m2, was given as a 3-hour continuous intravenous infusion and repeated every 21 days. Initially, ketoconazole, 100 to 1600 mg, was given as a single oral dose 3 hours after paclitaxel. Later, ketoconazole, 200 mg, was given perorally 3 hours before paclitaxel. Plasma drug concentrations were measured by high-pressure liquid chromatography (HPLC), and cytochrome P450 3A (CYP3A) activity was measured with the erythromycin breath test (ERMBT). Ketoconazole did not alter plasma concentrations of paclitaxel or its principal metabolite, 6 alpha-hydroxypaclitaxel. Although there was marked inter- and intrapatient variability in ketoconazole pharmacokinetics, peak plasma concentrations in all but one course were below the 50% inhibitory concentration (IC50) point determined for inhibition of paclitaxel metabolism in vitro. Therefore, paclitaxel and ketoconazole can be coadministered safely without dose adjustments. There was no correlation between ERMBT measurements and serial plasma concentrations of paclitaxel. The erythromycin breath-test measurements did correlate with the corresponding ketoconazole plasma concentrations. The erythromycin breath test is a valuable tool for measuring instantaneous CYP3A activity in vivo. This clinical study confirms the results of prior studies with human-derived materials in vitro, reinforcing the notion that such studies are useful predictors of drug pharmacokinetics and interactions in vivo.

Transcutaneous electrical nerve stimulation as an adjunct for controlling chemotherapy-induced nausea and vomiting in gynecologic oncology patients.

BACKGROUND: To evaluate the efficacy of a miniaturized portable transcutaneous electrical nerve stimulation (TENS) unit (ReliefBand) as an adjunct to standard antiemetic therapy for controlling nausea and vomiting induced by cisplatin-based chemotherapy in gynecologic oncology patients. METHODS: Forty-two patients were enrolled in a randomized, double-blind, placebo-controlled parallel-subjects trial with a follow-up crossover trial. All patients received a standardized antiemetic protocol, then wore the ReliefBand continuously for 7 days. RESULTS: Thirty-two patients were evaluable for the parallel-subjects component, 16 in each group. The percentage of patients with absent or minimal nausea was 59% overall, which was similar to that for both the active (56%) and placebo (62%) groups. The incidence and severity of nausea and vomiting was similar for each group. Eighteen patients completed two consecutive cycles and were evaluable for the crossover component. The average age of the crossover patients and their dose intensity were comparable with those of the overall study population (56.3 versus 58.6 years and 22.7 versus 22.7 mg/m2/week, respectively). The percentage of cycles with absent or minimal nausea was 47% overall, which was similar to that of the active (50%) and placebo (44%) cycles. However, the severity of nausea was significantly lower in the active cycles during days 2 to 4. Patients averaged less than one episode of vomiting daily in each cycle. CONCLUSIONS: The ReliefBand is an effective adjunct to standard antiemetic agents for controlling nausea induced by cisplatin-based chemotherapy in gynecologic oncology patients.

Synchronous dual primary ovarian and endometrial carcinomas.

OBJECTIVES: The synchronous occurrence of carcinoma confined to the ovary and endometrium presents a diagnostic and therapeutic dilemma. These tumors have been variously staged as FIGO Stage IIA ovarian carcinoma, Stage III endometrial carcinoma, or synchronous dual primary carcinomas. Accumulating evidence suggests such patients have a favorable outcome. This retrospective study was undertaken to review our experience with these fascinating tumors. METHODS: The clinical records and the pathologic findings of 16 patients with synchronous dual primary ovarian and endometrial carcinomas were reviewed. RESULTS: The median age was 51 years. Abnormal uterine bleeding was the most common presenting symptom (70%). All patients had Stage I ovarian and endometrial carcinomas. Fourteen patients (88%) had endometrioid carcinoma in both sites, while two patients (12%) had dissimilar histology. For 15 patients (94%), the grade of both tumors was identical. Only three (19%) patients had myometrial invasion, with less than 50% involvement in each case. All patients underwent surgical staging, 11 (70%) of whom received adjuvant radiation or chemotherapy. The five patients treated with surgery alone had Grade 1 endometrioid tumors. The only relapse occurred in a patient with a clear cell component in both sites. No patient has died of disease. CONCLUSIONS: Patients with synchronous dual primary carcinomas appear to have a more favorable prognosis than that expected with Stage IIA ovarian or Stage III endometrial carcinoma (100% vs. 63% or 42% survival at 3 years, respectively). The excellent survival for patients with Grade 1 dual endometrioid tumors treated with surgery alone suggests that adjuvant therapy may not be necessary for this sub-group.

Vaginal delivery from the persistent occiput posterior position. Influence on maternal and neonatal morbidity.

We performed a retrospective study of 564 vaginal occiput posterior (OP) deliveries to investigate the influence of this position on maternal and fetal morbidity. The cases were compared to 1,068 controls matched for race, parity and delivery method. The OP group had a higher incidence of severe perineal laceration and episiotomy than the occiput anterior (OA) group. Within the OP group, operative delivery was associated with a higher incidence of severe perineal laceration, vaginal laceration and episiotomy than was spontaneous delivery. Similarly, the OP group delivered by forceps had a higher incidence of severe perineal lacerations, vaginal lacerations and episiotomy than those delivered by vacuum extraction. Mediolateral episiotomy was associated with a lower incidence of severe perineal lacerations than median episiotomy during delivery from the OP position. The infants delivered from the OP position had a higher incidence of Erb's and facial nerve palsy than did those delivered from the OA position. All these injuries occurred following forceps delivery. Vaginal delivery from the persistent OP position is associated with increased maternal morbidity, and operative vaginal delivery from this position is associated with increased neonatal morbidity.

Open laparoscopy without special instruments or sutures. Comparison with a closed technique.

An important advantage of open laparoscopy over closed techniques is the avoidance of placing a sharp trocar blindly into the peritoneal cavity. Although an open technique theoretically minimizes the risk of major retroperitoneal vessel injury and bowel injury, most laparoscopies are performed using a closed technique. In an effort to simplify open laparoscopy, a technique was developed that can be done without special equipment or sutures and nearly as quickly as a closed technique. To compare the effectiveness of this open laparoscopic technique to a closed technique, a prospective, observational, cohort study was carried out on 66 women undergoing laparoscopy for either infertility or pelvic pain. The open technique was performed on 35 consecutive patients and compared to a closed technique performed on 31 patients on a different service during the same period. Evaluation included total duration of the procedure, length of the incision, incidence of CO2 leakage and complications. The open technique took slightly longer, and the incision was slightly longer. CO2 leakage occurred in 5 of 35 of the open cases but in none of the 31 closed cases. Leakage was controlled effectively in every case by application of a towel clip to the skin incision. No complications occurred with either technique. This study suggested that an open technique that requires no special equipment or sutures may be a useful alternative approach for laparoscopy when insertion of a sharp trocar is undesirable.

Neovaginal cytology after total pelvic exenteration for gynecological malignancies.

Vaginal reconstruction has become an established method to restore sexual function in women who have undergone ultraradical surgery and/or irradiation for the treatment of gynecologic malignancies. Cytologic evaluation of the neovagina serves a major role in the detection of recurrent disease. The purpose of this retrospective 6-yr study (January 1987-December 1993) was to evaluate the cytologic features of vaginal smear specimens from neovaginas constructed utilizing split-thickness skin grafts. Thirty-four vaginal smears were obtained at regular intervals from nine women (mean age: 51 yr) who underwent total pelvic exenteration with vaginal reconstruction for recurrent malignancies of the vagina and the cervix. Anucleated, keratinizing squames were a constant finding in each smear. Over a 4-mo-6-yr postoperative period, superficial and intermediate squamous cells were present in the majority of the smears and the maturation index showed a shift to the right. In two cases, a squamous cell carcinoma of the cervix recurred within the neovagina. Knowledge of the cytologic features associated with neovaginas is important in order to distinguish normal changes from neoplastic lesions.

Treatment of refractory ovarian carcinoma with paclitaxel and cisplatin after treatment failure with single-agent paclitaxel.

The clinical response to paclitaxel and cisplatin was evaluated in fifteen patients with refractory epithelial ovarian cancer who failed to respond to treatment with single agent paclitaxel. Patients received combination chemotherapy every 3 weeks with both 135 mg/m2 (9) or 175 mg/m2 (6) of paclitaxel and 50 mg/m2 (2), 75 mg/m2 (4) or 100 mg/m2 (9) of cisplatin. There was 1 complete clinical response, with 2 partial clinical responses for an overall response rate of 20%. The progression free interval was 6+ months for the complete responder and 9.5+ months for the partial responders. Overall five (33%) patients experienced an improvement in clinical response over that seen with paclitaxel alone, and 5 patients have died. Improvement in clinical response with combination chemotherapy compared to paclitaxel alone was positively associated with the cisplatin dose; while disease progression and death were inversely associated with the paclitaxel dose. Addition of cisplatin to paclitaxel may be useful in the treatment of patients who fail to respond to paclitaxel alone.
