Abstract
OBJECTIVE To assess the prognostic performance of the 2023 International Federation of Gynecology and Obstetrics (FIGO) endometrial cancer staging schema. METHODS This retrospective cohort study queried the Commission-on-Cancer's National Cancer Database. Study population was 129,146 patients with stage I-IV endometrial cancer per the 2009 FIGO staging schema. Stage-shifting and overall survival (OS) were assessed according to the 2023 FIGO staging schema. RESULTS Upstage (IA → II, 21.4 %; IB → II, 53.0 %) and downstage (IIIA→IA3, 22.2 %) occurred in both early and advanced diseases. Inter-stage prognostic performance improved in the 2023 schema with widened 5-year OS rate difference between the earliest and highest stages (68.2 % to 76.9 %). Stage IA1-IIB and IIC had distinct 5-year OS rate differences (85.8-96.1 % vs 75.4 %). The 5-year OS rate of the 2009 stage IIIA disease was 63.9 %; this was greater segregated in the 2023 schema: 88.0 %, 62.4 %, and 55.7 % for IIIA→IA3, IIIA1, and IIIA2, respectively (inter-substage rate-difference, 32.3 %). This 5-year OS rate of stage IA3 disease was comparable to the 2023 stage IB-IIB diseases (88.0 % vs 85.8-89.5 %). In the 2023 stage IIIC schema (micrometastasis rates: 29.6 % in IIIC1 and 15.6 % in IIIC2), micrometastasis and macrometastasis had the distinct 3-year OS rates in both pelvic (IIIC1-i vs IIIC1-ii, 84.9 % vs 71.1 %; rate-difference 13.8 %) and para-aortic (IIIC2-i vs IIIC2-ii, 82.9 % vs 65.2 %; rate-difference 17.7 %) nodal metastasis cases. The 5-year OS rate of the 2009 stage IVB disease was 23.4 %; this was segregated to 25.4 % for stage IVB and 19.2 % for stage IVC in the 2023 staging schema (rate-difference, 6.2 %). CONCLUSION The 2023 FIGO endometrial cancer staging schema is a major revision from the 2009 FIGO schema. Almost doubled enriched sub-stages based on detailed anatomical metastatic site and incorporation of histological information enable more robust prognostication.

Abstract
OBJECTIVE Failure-to-rescue, defined as mortality following a perioperative complication, is a perioperative quality indicator studied in various surgeries, but not in vulvar cancer surgery. The objective of this study was to assess failure-to-rescue in patients undergoing surgical therapy for vulvar cancer. METHODS This cross-section study queried the National Inpatient Sample. The study population was 31,077 patients who had surgical therapy for vulvar cancer from 1/2001-9/2015. The main outcomes were (i) perioperative morbidity (29 indicators) and (ii) mortality following a perioperative complication during the index admission for vulvar surgery (failure-to-rescue), assessed with a multivariable binary logistic regression model. RESULTS The cohort-level median age was 69 years, and 14,337 (46.1%) had medical comorbidity. Perioperative complications were reported in 4736 (15.2%) patients during the hospital admission for vulvar surgery. In multivariable analysis, patient factors including older age, medical comorbidity, and morbid obesity, and treatment factors with prior radiotherapy and radical vulvectomy were associated with perioperative complications (P < 0.05). The number of patients with morbid obesity, higher comorbidity index, and prior radiotherapy increased over time (P-trends < 0.001). Among 4736 patients who developed perioperative complications, 55 patients died during the hospital admission for vulvar surgery (failure-to-rescue rate, 1.2%). In multivariable analysis, cardiac arrest (adjusted-odds ratio [aOR] 27.25), sepsis or systemic inflammatory response syndrome (aOR 11.54), pneumonia (aOR 6.03), shock (aOR 4.37), and respiratory failure (aOR 3.10) were associated with failure-to-rescue (high-risk morbidities). There was an increasing trend of high-risk morbidities from 2.0% to 3.7% over time, but the failure-to-rescue from high-risk morbidities decreased from 9.1% to 2.8% (P-trend < 0.05). CONCLUSION Vulvar cancer patients undergoing surgical treatment had increased comorbidity over time with an increase in high-risk complications. However, failure-to-rescue rate has decreased significantly.

Abstract
BACKGROUND Eribulin a microtubule targeting agent and analog of Halichondrin B, a natural product isolated from marine sponge H. okadai, has proven clinical efficacy in metastatic pretreated breast cancer and liposarcoma. We conducted a 2-stage Phase II study of eribulin in patients with advanced/recurrent cervical cancer to examine its clinical activity and evaluate biomarkers for predictors of response. METHODS Women with advanced/recurrent cervical cancer after ≤1 prior chemotherapy regimen, measurable disease and ECOG performance status ≤2 were treated with eribulin (1.4 mg/m2 IV day 1 and 8, every 21 days) with tumor assessments every 2 cycles. Primary endpoint was 6-month progression-free survival (PFS6); secondary were best overall response (RECISTv1.1), toxicity (CTCAEv4.03) and overall survival (OS). Exploratory endpoints were associations of biomarkers with clinical activity. Immunohistochemistry was performed on archival tumor samples. Overexpression was defined when both intensity and distribution scores were ≥ 2. RESULTS 32 patients enrolled from 11/2012-5/2017. 29/32 patients had prior chemotherapy with cisplatin/paclitaxel/bevacizumab (n = 12) or cisplatin/gemcitabine (n = 12) as the most common regimens. 14 patients received prior paclitaxel. 1 (3%) had a complete response, 5 (16%) had a partial response and 13 (41%) had stable disease for ORR of 19% (95% CI 8, 37). Those who are paclitaxel naïve experienced the greatest benefit with a 29% ORR (95% CI 12, 54). Patients who received prior paclitaxel responded less favorably than those who did not (p = .002) and had a shorter PFS and OS. Grade 3/4 adverse events occurring in >10% of patients were anemia (n = 12, 38%), neutropenia (n = 7, 22%) and leukopenia (n = 6, 19%). Analysis of correlative predictors of response revealed that patients who did not overexpress βII and BAX were significantly more likely to respond to e`ribulin. PFS was significantly shorter in patients with βII and BAX overexpression, OS was significantly shorter in those with βIII and BAX overexpression. These associations remained after multivariate analysis. CONCLUSIONS Eribulin shows modest activity in patients with recurrent/advanced cervical cancer with a favorable toxicity profile. Prior paclitaxel exposure is associated with decreased eribulin response. βII, βIII tubulin subtypes and BAX are predictors of response and survival. Eribulin may be an option for women with paclitaxel-naïve recurrent/advanced cervical cancer.

Abstract
BACKGROUND AND OBJECTIVES Low anterior rectosigmoid resection for a gynecologic disease is usually performed in concert with other procedures and can result in significant morbidity should anastomotic complication occur. This study examined surgical outcomes of side-to-end reanastomosis after low anterior resection (STELAR) performed by gynecologic oncology service. METHODS This is a case series examining consecutive patients who underwent STELAR for gynecologic indications by a single gynecologic oncology group from 2009 to 2018. Prospectively collected institutional surgical database was searched for STELAR, and standard descriptive statistics were used to describe intraoperative and postoperative complications specific to reanastomosis. RESULTS A total of 69 women underwent STELAR, with median age and body mass index of 54 years and 24 kg/m2 , respectively. 63.8% of patients had ovarian cancer and 84.4% had stage III-IV disease. The median estimated blood loss was 875 ml. Four (5.8%) women underwent protective loop colostomy at the time of STELAR. Postoperatively, there was 1 (1.4%) case of abscess formation within 30 days and 1 (1.4%) case of anastomotic leak 5 weeks after STELAR that required reoperation and diversion. No cases of fistula were clinically identified. CONCLUSION Side-to-end reanastomosis may be a safe and feasible procedure to accomplish low rectosigmoid anastomosis in women with gynecologic disease.

Abstract
OBJECTIVE To examine population-level trends, characteristics, and outcomes of patients with stage IVB endometrial cancer who received neoadjuvant chemotherapy (NACT) prior to surgery. METHODS The National Cancer Institute's Surveillance, Epidemiology, and End Results Program was retrospectively queried by examining 5505 patients with stage IVB endometrial cancer from 2010 to 2018. Exposure allocation was per treatment: primary surgery followed by chemotherapy (n = 3052, 55.4%), NACT followed by surgery (n = 930, 16.9%), and chemotherapy alone (n = 1523, 27.7%). Main outcomes measured were (i) the trend of utilization of NACT and patient characteristics related to NACT assessed with multinomial regression analysis and (ii) overall survival (OS) assessed with multivariable Cox proportional hazards regression model. RESULTS The number of patients receiving NACT prior to surgery increased from 11.6% to 21.7% whereas those undergoing primary surgery followed by chemotherapy decreased from 62.7% to 48.3% (P < 0.001). Increasing utilization of NACT remained independent in multivariable analysis (adjusted-odds ratio per one-year increments 1.11, 95% confidence interval [CI] 1.08-1.15). Increasing utilization of NACT was observed in several sub-cohorts including patients aged <65 years, ≥65 years, White, non-White, endometrioid, non-endometrioid, and cases with non-distant organ metastasis (P < 0.05). In a multivariable analysis, NACT followed by surgery and primary surgery followed by chemotherapy had comparable OS (median 25 versus 26 months, adjusted-hazard ratio [HR] 1.03, 95%CI 0.93-1.15). When examined for metastatic extent, NACT followed by surgery was associated with decreased OS compared to primary surgery followed by chemotherapy in the non-distant organ metastasis group (adjusted-HR 1.20, 95%CI 1.05-1.36) whereas it was associated with improved OS in the distant organ metastasis group (adjusted-HR 0.79, 95%CI 0.66-0.95). CONCLUSION The treatment of stage IVB endometrial cancer is shifting from primary surgery to NACT in the United States.

Abstract
OBJECTIVE To examine trends and outcomes related to sentinel lymph node (SLN) biopsy for stage II endometrial cancer. METHODS This is a retrospective observational cohort study querying the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. The study population was 6,314 women with T2 endometrial cancer who underwent hysterectomy from 2010-2018. Exposure allocation was based on nodal evaluation type: lymphadenectomy (LND; n=4,915, 77.8%), SLN biopsy (n=340, 5.4%), or no surgical nodal evaluation (n=1,059, 16.8%). The main outcomes were (i) trends and characteristics related to nodal evaluation assessed by multinomial regression, and (ii) overall survival (OS) assessed by an inverse probability of treatment weighting propensity score analysis. A sensitivity analysis was performed to examine concurrent LND in women who underwent SLN biopsy. RESULTS The utilization of SLN biopsy increased from 1.6% to 16.1%, while the number of LND decreased from 81.5% to 65.7% between 2010-2018 (P<0.05). In multivariable analysis, the utilization of SLN biopsy increased 45% annually (adjusted-odds ratio 1.45, 95% confidence interval [CI] 1.37-1.54, P<0.001). The frequency of SLN biopsy alone exceeded the frequency of SLN biopsy with concurrent LND in 2017 (6.8% versus 3.4%), followed by continued increase in SLN biopsy alone (11.2% versus 4.9%) in 2018. In the weighted model, the 3-year OS rate was 79.9% for the SLN biopsy group and 78.6% for the LND group (hazard ratio 0.98, 95%Cl 0.80-1.20, P=0.831). Similarly, the SLN biopsy alone without concurrent LND had comparable OS compared to the LND group (hazard ratio 0.90, 95%CI 0.59-1.36, P=0.615). CONCLUSION Utilization of SLN biopsy in stage II endometrial cancer increased significantly over time, and SLN biopsy-incorporated nodal assessment was not associated with worsened short-term survival outcome.

Abstract
OBJECTIVE The aim of this study was to determine the association between weight change patterns and survival outcomes of women with endometrial cancer. METHODS This retrospective study examined surgically-staged endometrial cancer cases with available weight information between 1999 and 2013 (n = 665). Proportional body mass index (delta-BMI) change at 6 months, 1 and 2 years after hysterectomy was compared with baseline BMI and correlated to patient demographics, tumor characteristics, treatment type, and disease-free survival (DFS) and overall survival (OS). RESULTS Mean BMI was 35.6, and 69 % of cases were obese. At 6 months, 1 and 2 years after surgery, 39.1, 51.6, and 57.0 % of the study population, respectively, gained weight compared with pre-treatment baseline. In univariate analysis, 6-month delta-BMI change was significantly associated with DFS and OS, demonstrating bidirectional effects (both p < 0.001): 5-year rates, ≥15.0 % delta-BMI loss (33.5 and 59.1 %), 7.5-14.9 % loss (67.3 and 70.0 %), <7.5 % loss (87.8 and 95.7 %), <7.5 % gain (87.2 and 90.3 %), 7.5-14.9 % gain (64.6 and 67.6 %), and ≥15.0 % gain (32.5 and 66.7 %). In multivariable analysis controlling for age, ethnicity, baseline BMI, histology, grade, stage, chemotherapy, and radiotherapy, 6-month delta-BMI change remained an independent prognostic factor for DFS and OS (all p < 0.05): adjusted hazard ratios, ≥15 % delta-BMI loss (3.35 and 5.39), 7.5-14.9 % loss (2.35 and 4.19), 7.5-14.9 % gain (2.58 and 3.33), and ≥15.0 % gain (2.50 and 3.45) compared with <7.5 % loss. Similar findings were observed at a 1-year time point (p < 0.05). Baseline BMI was not associated with survival outcome (p > 0.05). CONCLUSION Our results demonstrated that endometrial cancer patients continued to gain weight after hysterectomy, and post-treatment weight change had bidirectional effects on survival outcome.

Abstract
Human papillomavirus (HPV)-mediated suppression of Langerhans cell (LC) function can lead to persistent infection and development of cervical intraepithelial neoplasia (CIN). Women with HPV-induced high-grade CIN2/3 have not mounted an effective immune response against HPV, yet it is unknown if LC-mediated T cell activation from such women is functionally impaired against HPV. We investigated the functional activation of in vitro generated LC and their ability to induce HPV16-specific T cells from CIN2/3 patients after exposure to HPV16 followed by treatment with stabilized Poly-I:C (s-Poly-I:C). LC from patients exposed to HPV16 demonstrated a lack of costimulatory molecule expression, inflammatory cytokine secretion, and chemokine-directed migration. Conversely, s-Poly-I:C caused significant phenotypic and functional activation of HPV16-exposed LC, which resulted in de novo generation of HPV16-specific CD8(+) T cells. Our results highlight that LC of women with a history of persistent HPV infection can present HPV antigens and are capable of inducing an adaptive T cell immune response when given the proper stimulus, suggesting that s-Poly-I:C compounds may be attractive immunomodulators for LC-mediated clearance of persistent HPV infection.

Abstract
BACKGROUND To examine the effects of adenomyosis on tumor progression and survival outcome of endometrial cancer patients. METHODS This is a retrospective study examining stage I-IV endometrial cancer patients who underwent hysterectomy-based surgical staging (n = 571), and endometrial hyperplasia patients who underwent hysterectomy (n = 213). Clinical demographics, histopathological factors, and survival outcomes were analyzed based on the presence or absence of adenomyosis. RESULTS Among the endometrial cancer cohort, adenomyosis was observed in 47.5 % of cases and was significantly associated with lower grade (grade 1-2 tumors, 81.2 vs. 73.3 %; p = 0.028), earlier stage (stage I disease, 74.8 vs. 64.3 %; p = 0.023), and lower likelihood of deep myometrial invasion (19.2 vs. 28.2 %; p = 0.039) and cervical invasion (13.7 vs. 21.2 %; p = 0.024) than those without adenomyosis. In survival analysis, endometrial cancer coexisting with adenomyosis was associated with a significantly better disease-free survival (5-year rate, 89.2 vs. 78.2 %; p < 0.001) and overall survival (91.8 vs. 83.9 %; p = 0.004) after hysterectomy. In multivariate analysis, controlling for other significant variables in univariate analysis, presence of adenomyosis remained an independent prognostic factor associated with decreased risk of disease recurrence after surgery (hazard ratio [HR] 0.53; 95 % confidence interval [CI] 0.30-0.92; p = 0.023). Endometrial hyperplasia had a significantly increased incidence of adenomyosis when compared with type I endometrial cancer (grade 1-2 endometrioid adenocarcinoma, n = 411) on multivariate analysis (62.9 vs. 48.9 %; HR 1.88; 95 % CI 1.32-2.69; p < 0.001). CONCLUSIONS Adenomyosis appears to be associated with less aggressive tumor behavior of endometrial cancer, suggesting that it may have inhibitory effects on the progression of this disease.

Abstract
OBJECTIVE To determine the preoperative pelvic ultrasonographic characteristics of postmenopausal women diagnosed with endometrial cancer (EC) at our institution. METHODS Postmenopausal women with EC who underwent preoperative transvaginal pelvic ultrasound from 1999-2009 were identified from our institutional database. The histologic diagnosis was based on pathologic findings in the hysterectomy specimen. Endometrial echo complex (EEC) thickness was abstracted from ultrasound reports. In all instances, ultrasound preceded the biopsy by a maximum of 3 months. Means with standard deviations were calculated for all categorical data. Differences between type 1 and type 2 ECs were determined using Mann-Whitney U tests and Chi squared/Fisher's exact tests, as appropriate. A p-value of <0.05 was considered statistically significant. RESULTS Among 250 patients with postmenopausal EC, 156 had type 1 EC while 94 had type 2 EC. Thirty-six percent of the cohort had an EEC ≤ 4 mm, including 37% of patients with type 1 EC and 34% of patients with type 2 EC (p=0.63). There were no significant differences between type 1 and type 2 ECs in any demographic characteristic, other than likelihood of postmenopausal bleeding. CONCLUSIONS Current expert opinion recommends no further diagnostic procedure in a woman with postmenopausal bleeding and an EEC ≤ 4 mm. These results indicate that a sizable proportion of women with EC have EECs ≤ 4 mm during their initial evaluation. An EEC ≤ 4 mm does not completely rule out endometrial cancer and cannot supplant histologic evaluation.

Abstract
While highly effective for treating certain gynecologic malignancies, radiotherapy carries known risks, including fistula formation. We report a 75-year-old female with advanced cervical carcinoma who was provided a vaginally placed fecal management system after developing a rectovaginal fistula following primary treatment with chemoradiation. This report presents and discusses a novel method to palliate symptomatic RVFs in advanced-stage cancer.

Abstract
Cancer-related coping strategies and social support, life stress, and optimism were tested in regression analyses as predictors of depression, affect, and quality of life among 54 low-income, immigrant Latina cervical cancer patients. Sixty-seven percent of the patients endorsed symptoms similar to diagnosable depression. Predictors significantly accounted for 35% to 54% of the variance in outcomes. Cancer-related coping strategies were found to mediate several of the relations between life stress, social support, and optimism and outcomes. Findings emphasize the need to consider the context within which patients live when assessing adjustment to cancer and developing culturally-sensitive interventions.

Abstract
OBJECTIVE The objective of the study was to confirm that concurrent cisplatin (CT) with radiation therapy (RT) is associated with improved long-term progression-free survival (PFS) and overall survival (OS), compared with RT alone in stage IB bulky carcinoma of the cervix, when both groups' therapy is followed by hysterectomy. STUDY DESIGN Three hundred seventy-four patients entered this trial. There were 369 evaluable patients; 186 were randomly allocated to receive RT alone and 183 to receive CT plus RT. Radiation dosage was 45 Gray (Gy) in 20 fractions followed by low dose-rate intracavitary application(s) of 30 Gy to point A. Chemotherapy consisted of intravenous cisplatin 40 mg/m2 every week for up to 6 weekly cycles. Total extrafascial hysterectomy followed the completion of RT by 6-8 weeks. RESULTS Preliminary results have been published, at which time there were 292 censored observations, and median duration of follow-up was only 36 months. Patient and tumor characteristics were well balanced between the regimens. The median patient age was 41.5 years; 81% had squamous tumors; 59% were white. Median follow-up is now 101 months. The relative risk for progression was 0.61 favoring CT plus RT (95% confidence interval [CI] 0.43 to 0.85, P < .004). At 72 months, 71% of patients receiving CT plus RT were predicted to be alive and disease free when adjusting for age and tumor size, compared with 60% of those receiving RT alone. The adjusted death hazard ratio was 0.63 (95% CI 0.43 to 0.91, P < .015) favoring CT plus RT. At 72 months, 78% of CT plus RT patients were predicted to be alive, compared with 64% of RT patients. An increased rate of early hematologic and gastrointestinal toxicity was seen with CT plus RT. There was no detectable difference in the frequency of late adverse events. CONCLUSION Concurrent weekly cisplatin with RT significantly improves long-term PFS and OS when compared with RT alone. Serious late effects were not increased. The inclusion of hysterectomy has been discontinued on the basis of another trial. Pending further trials, weekly cisplatin with radiation is the standard against which other regimens should be compared.

Abstract
Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV) infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

Abstract
OBJECTIVE Approximately 2 million women worldwide are infected with high-risk human papillomaviruses (HPV), resulting in a substantial risk for the development of invasive lower genital malignancies. This study was undertaken to determine the effects of vaccination with a protein encoding a bacterial heat shock protein fused to sequences from the oncogenic E7 protein of HPV-16 in women with high-grade cervical intraepithelial neoplasia. Endpoints included lesion regression, immune response, and viral clearance. METHODS Twenty-one women were prospectively entered into an IRB-approved Phase II study. All women had biopsy-proven high-grade cervical intraepithelial neoplasia and persistent post-biopsy lesions visible by colposcopy. Four injections of HPV-16 Hsp E7 fusion protein at a dose of 500 mug were given 3 weeks apart after which Loop Electrosurgical Excision of the Transformation Zone (LLETZ) was performed. Immune parameters were evaluated pre-vaccine and at the time of LLETZ, and HPV testing was performed at intervals before and after LLETZ. Study subjects were followed for 1 year after LLETZ. RESULTS Seven of 20 women (35%) evaluable for response had complete regression of their intraepithelial neoplasia at the time of LLETZ, 1 (5%) had regression to CIN I, 11 (55%) had stable disease and 1 (5%) had progression due to enlargement of her lesion. Immune responses were seen in 9 of the 17 women tested; 5 of the 7 complete responders had an immune response. Only 5 of 21 women had HPV-16 or -18. HPV clearance was not associated with lesion regression. CONCLUSION Hsp-7 (SGN-00101), at this dose and schedule induced lesion regression in women with high-grade intraepithelial neoplasia. The fact that regression was correlated with immune response suggests that enhancing the immunogenicity of this vaccine may lead to improvement in the rate of lesion eradication.

Abstract
STUDY OBJECTIVE Feasibility of laparoscopic extraperitoneal surgical staging for locally advanced cervical carcinoma in a gynecologic oncology fellowship training program. DESIGN Retrospective analysis (II-2) of all patients who underwent laparoscopic extraperitoneal surgical staging at Women and Children's Hospital for locally advanced cervical cancer between June 2002 and June 2005. SETTING Gynecologic oncology fellowship training program at a University-County Hospital PATIENTS Thirty-two patients with clinical stage IIB-IVA cervical carcinoma were identified. INTERVENTIONS Laparoscopic extraperitoneal surgical staging for clinical stage IIB-IVA cervical cancer. MEASUREMENTS AND MAIN RESULTS A total of 32 cases of laparoscopic extraperitoneal surgical staging for locally advanced cervical cancer performed by fellows-in-training were identified. Fellows were first assistant surgeon in 10 cases, and operating surgeon in 22 cases. Each fellow was mentored an average of 5 cases as first assistant surgeon. As operating surgeon, all 22 fellow cases (100%) were successfully performed without conversion to laparotomy. Fellow mean operative time was 163 minutes. Fellow mean aortic nodal count was 14. Fellow mean blood loss was 42 mL. The mean hospital stay was 1.6 days. Overall, 2 patients (6.2%) experienced a complication from the procedure. Over one half (53%) of the patients reported a prior abdominal surgery. No lymphedema has been reported in patients who underwent laparoscopic extraperitoneal surgical staging with a median follow-up of 10 months. Surgical comorbidities such as hypertension, diabetes, and obesity were common in the study group. A steep surgical learning curve for the fellows was demonstrated by comparing mean operative times to academic year. Aortic nodal metastasis was detected in 25% of cases, and 14% were occult. CONCLUSIONS It is feasible to teach laparoscopic extraperitoneal surgical staging to fellows-in-training. Our data suggest that by the end of training, fellows can become proficient with the procedure and are capable of surgical outcomes and complication rates comparable to reported literature.

Abstract
PURPOSE To investigate, in a phase III randomized trial, whether postoperative external-beam irradiation to the standard pelvic field improves the recurrence-free interval and overall survival (OS) in women with Stage IB cervical cancers with negative lymph nodes and certain poor prognostic features treated by radical hysterectomy and pelvic lymphadenectomy. METHODS AND MATERIALS Eligible patients had Stage IB cervical cancer with negative lymph nodes but with 2 or more of the following features: more than one third (deep) stromal invasion, capillary lymphatic space involvement, and tumor diameter of 4 cm or more. The study group included 277 patients: 137 randomized to pelvic irradiation (RT) and 140 randomized to observation (OBS). The planned pelvic dose was from 46 Gy in 23 fractions to 50.4 Gy in 28 fractions. RESULTS Of the 67 recurrences, 24 were in the RT arm and 43 were in the OBS arm. The RT arm showed a statistically significant (46%) reduction in risk of recurrence (hazard ratio [HR] = 0.54, 90% confidence interval [CI] = 0.35 to 0.81, p = 0.007) and a statistically significant reduction in risk of progression or death (HR = 0.58, 90% CI = 0.40 to 0.85, p = 0.009). With RT, 8.8% of patients (3 of 34) with adenosquamous or adenocarcinoma tumors recurred vs. 44.0% (11 of 25) in OBS. Fewer recurrences were seen with RT in patients with adenocarcinoma or adenosquamous histologies relative to others (HR for RT by histology interaction = 0.23, 90% CI = 0.07 to 0.74, p = 0.019). After an extensive follow-up period, 67 deaths have occurred: 27 RT patients and 40 OBS patients. The improvement in overall survival (HR = 0.70, 90% CI = 0.45 to 1.05, p = 0.074) with RT did not reach statistical significance. CONCLUSIONS Pelvic radiotherapy after radical surgery significantly reduces the risk of recurrence and prolongs progression-free survival in women with Stage IB cervical cancer. RT appears to be particularly beneficial for patients with adenocarcinoma or adenosquamous histologies. Circumstances that may have influenced the overall survival differences are considered.

Abstract
In this study, we examine the prevalence of finding isolated tumor cells (ITCs) in negative lymph nodes of endometrial cancer patients using immunohistochemistry. Seventy-six endometrial cancer patients with lymph nodes histologically negative for metastatic disease were examined. Nodal tissue sections were stained with anticytokeratin antibodies AE-1 and CAM 5.2. Nodes with single or groups of cells (two to four cells) < or =0.2 mm and showing cytokeratin reactivity were positive for ITCs. Findings were compared to features of the primary tumor and patient outcome. ITCs were present in 31 of 1712 lymph nodes. Fifteen (19.7%) patients had ITC-positive nodes. ITCs involved only pelvic nodes in nine cases, only para-aortic nodes in five cases, and pelvic and para-aortic in one case. Tumor in adnexa was the only pathologic feature associated with nodal ITCs (P= 0.0485). All 15 patients with nodal ITCs were alive at follow-up. One (6.7%) patient suffered recurrent disease but was alive at last encounter. Disease recurred in 5 (8.8%) of 57 patients without nodal ITCs. Two are alive without disease, two alive with disease, and one died from her cancer. In summary, a significant proportion of endometrial cancer patients have ITCs detected by immunohistochemistry in histologically negative regional lymph nodes.

Abstract
OBJECTIVE To determine if the quantity of lymph vascular space invasion (LVSI) correlates with time to recurrence in women with early-stage squamous carcinoma of the cervix. METHODS 101 consecutive women with Stages IA2, IB, and IIA squamous carcinoma of the cervix who had undergone radical hysterectomy between 1991 and 1997, with previously reported histopathologic quantification of LVSI by four methods, were prospectively followed. The outcome measure was time to recurrence. Univariate and stratified log-rank test analysis was performed to test the association of time to recurrence with prognostic factors. Further analysis was focused on recurrence in those patients who had negative surgical margins and whose tumors contained LVSI, incorporating the four quantification measures. RESULTS Nineteen (19%) women had cancer recurrence. The presence of LVSI (P = 0.05), cervical stromal invasion (P = 0.01), parametrial involvement (P < 0.001), and positive margins (P < 0.0001) were significantly related to time to recurrence on univariate analysis. In patients whose tumors had negative surgical margins and contained LVSI (65%), percentage of all sections with LVSI >29% and total number of foci with LVSI >5 were significantly related to time to recurrence (P = 0.006). When stratifying for cervical stromal invasion, lymph node status, and parametrial involvement in this group, percentage of all sections with LVSI >29% and total number of foci with LVSI >5 were significantly related to time to recurrence (P = 0.05). CONCLUSION The quantity of LVSI, as defined by the percentage of all sections with LVSI and total number of foci with LVSI, is an independent prognostic factor for time to recurrence in women with early-stage squamous carcinoma of the cervix.

Abstract
Cervical cancer is the second most common cause of cancer-related deaths in women worldwide. Screening for cervical cancer is accomplished utilizing a Pap smear and pelvic exam. While this technology is widely available and has reduced cervical cancer incidence in industrialized nations, it is not readily available in third world countries in which cervical cancer incidence and mortality is high. Development of cervical cancer is associated with infection with high risk types of human papillomavirus (HPV) creating a unique opportunity to prevent or treat cervical cancer through anti-viral vaccination strategies. Several strategies have been examined in clinical trials for both the prevention of HPV infection and the treatment of pre-existing HPV-related disease. Clinical trials utilizing prophylactic vaccines containing virus-like particles (VLPs) indicate good vaccine efficacy and it is predicted that a prophylactic vaccine may be available within the next five years. But, preclinical research in this area continues in order to deal with issues such as cost of vaccination in underserved third world populations. A majority of clinical trials using therapeutic agents which aim to prevent the progression of pre-existing HPV associated lesions or cancers have shown limited efficacy in eradicating established tumors in humans possibly due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Future trends in clinical trials with therapeutic agents will examine patients with early stage cancers or pre-invasive lesions in order to prevent invasive cervical cancer. Meanwhile, preclinical studies in this field continue and include the further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. Given that cervical cancers are caused by the human papillomavirus, the prospect of therapeutic vaccination to treat existing lesions and prophylactic vaccination to prevent persistent infection with the virus are high and may be implemented in the near future. The consequences for clinical management may include a significant reduction in the frequency of Pap smear screening in the case of prophylactic vaccines, and the availability of less invasive and disfiguring treatment options for women with pre-existing HPV associated lesions in the case of therapeutic vaccines. Implementation of both prophylactic and therapeutic vaccine regimens could result in a significant reduction of health care costs and reduction of worldwide cervical cancer incidence.

Abstract
OBJECTIVE Despite histologically negative lymph nodes, approximately 15% of patients with early-stage cervical cancer will develop recurrence. Micrometastases have been shown to be important in staging and treatment of breast cancers and melanoma and have been identified by polymerase chain reaction analysis in cervical cancers. This study sought to estimate the frequency of micrometastases identified by immunohistochemistry in histologically negative lymph nodes and compare this to other known risk factors for recurrence of cervical cancer. METHODS Early-stage (stages IA2, IB1, and IB2) cervical cancer patients of all histologic subtypes were identified from the surgical logs of the Los Angeles County-University of Southern California Medical Center for the period 1994-2000. One hundred thirty-two patients had histologically negative lymph nodes. Immunohistochemical assay was performed on 3,106 lymph nodes by using antibodies against cytokeratins AE-1 and CAM 5.2 in combination according to standard protocols. The stained nodes were then evaluated for the presence of micrometastases and compared against the respective clinicopathologic information in each case. RESULTS Micrometastases were detected in 19 of 132 (15%, 95% confidence interval [CI] 9%, 22%) patients, found in 29 of the 3,106 (0.9%) lymph nodes evaluated. Vascular space invasion was seen in 50 of 132 cases (38%, 95% CI 30%, 47%) and in 8 of 19 (42%, 95% CI 21%, 66%) cases with micrometastases. Surgical margins of the resected specimen were negative in 120 of 132 cases (91%, 95% CI 84%, 95%) and in 16 of 19 (84%, 95%CI 60%, 96%) of those cases with micrometastases. Micrometastases were seen most frequently in pelvic lymph nodes (25 of 29, 86%). Patients with more than 20 lymph nodes removed were more likely to demonstrate metastasis (P <.001). There was no statistically significant association between micrometastasis and vascular space invasion or tumor volume. CONCLUSION Micrometastases are identifiable in histologically negative lymph nodes in 15% (95% CI 9%, 22%) of early-stage cancer patients, a frequency which approximates the recurrence rate for patients with negative nodes. In this series, patients with greater numbers of lymph nodes analyzed were more likely to have lymph node micrometastasis identified. There appears to be no relationship between tumor volume and the identification of micrometastases. Although micrometastases can be identified in histologically negative lymph nodes, their presence is not strongly associated with other known factors of cervical cancer recurrence. Further research is needed to determine whether the presence of lymph node micrometastases is associated with an unfavorable prognosis. LEVEL OF EVIDENCE II-3

Abstract
OBJECTIVE The purpose of this study was to evaluate the safety of the administration of a bacterial expression plasmid encoding a 13 amino acid sequence that is highly homologous with human papillomavirus E7 within poly (lactide-co-glycolide) microparticles (ZYC101) in women with HLA A2+ antigen and persistent cervical intraepithelial neoplasia grade 2/3 and human papillomavirus 16. STUDY DESIGN Fifteen women entered an institutional review board-approved dose-escalating phase I study with the use of three levels of blood monitoring and urine studies, Papanicolaou tests, and colposcopy. Escalation required no serious adverse events. Immunologic responses were evaluated in peripheral blood with the use of human papillomavirus peptide-stimulated interferon gamma enzyme-linked immunosorbent assay for T-cell reactivity. In cervical secretions, immunoglobulin A anti-human papillomavirus 16 E2 concentrations were measured. Three doses every 3 weeks were followed 4 weeks later by surgical excision. RESULTS No serious adverse events occurred. Five women had complete histologic responses; 11 women had human papillomavirus-specific T-cell responses. Four of five complete histologic responses developed immunoglobulin A anti-E2-specific antibody. CONCLUSION ZYC101 warrants further investigation because of a 33% complete histologic responses, a 73% immunologic response, and no serious adverse events.

Abstract
OBJECTIVE To determine associations among cervical cytology, colposcopy, and biopsy in HIV-seropositive women. MATERIALS AND METHODS HIV-seropositive women and uninfected comparison women in a multicenter prospective cohort study underwent colposcopy for protocol indications. Women were eligible if they had a cervix, satisfactory cytology, and colposcopy between October 1994 and September 1999. Cytology, colposcopic impression, and biopsy were compared using equivalent categorizations. Kappa statistics with bootstrap sampling assessed strength of associations. RESULTS Colposcopy was performed in 978/1370 HIV-seropositive women and in 154/224 seronegative women. Biopsies were performed on 603 (44%) seropositive women at least once during 1015 colposcopy visits and on 82 (37%) seronegative women at 116 visits. The positive predictive value of cytology was 72% for seropositive women and 60% for seronegative women. The positive predictive value of colposcopy was 71% for seropositive women and 55% for seronegative women. CONCLUSION The correlation between either cervical cytology or colposcopic impression and colposcopic biopsy was poor.

Abstract
OBJECTIVE To determine incidence, progression, and regression rates for abnormal cervical cytology and their correlates among women with HIV. METHODS In a multicenter prospective cohort study conducted October 1, 1994, through September 30, 1999 at university, public, and private medical centers and clinics, 1639 HIV-seropositive and 452 seronegative women were evaluated every 6 months for up to 5 years using history, cervical cytology, T-cell subsets, and quantitative plasma HIV RNA. Human papillomavirus (HPV) typing at baseline was determined by polymerase chain reaction. Cytology was read using the Bethesda system, with any smear showing at least atypia considered abnormal. Poisson regression identified factors associated with incident cytologic abnormalities whereas logistic regression identified those associated with progression and regression after an abnormality. RESULTS At least one abnormal smear was found during all of follow-up among 73.0% of HIV-seropositive patients and 42.3% of seronegatives (p <.001). Only 5.9% of seropositives ever developed high-grade lesions, and the proportion with high-grade findings did not rise over time. Incidence of atypical squamous cells of uncertain significance (ASCUS) or more severe lesions among HIV-seropositive patients and seronegative patients was 26.4 and 11.0/100 woman-years (rate ratio [RR], 2.4; 95% confidence interval [CI], 1.9-3.0), whereas that of at least low-grade squamous intraepithelial lesions (SIL) was 8.9 and 2.2/100 (RR, 4.0; CI, 2.6-6.1). HIV status, detection of the presence of human papillomavirus (HPV), CD4 lymphocyte count, and HIV RNA level predicted incidence of abnormal cytology (p <.05); HPV detection and HIV RNA level predicted progression (p <.01); and HPV detection, CD4 lymphocyte count, and HIV RNA level predicted regression (p <.001). Rates of incidence, progression, and regression of abnormal cytology did not differ between HIV seronegative women and seropositive women with CD4 lymphocyte counts >200/mm(3) and HIV RNA levels <4000/ml of similar HPV status. CONCLUSIONS Although HIV infected women were at high risk for abnormal cytology, high-grade changes were uncommon. HIV status, HPV detection, CD4 lymphocyte count, and HIV RNA level predicted the incidence of cervical cytologic abnormalities. Progression was significantly increased only among the most immunosuppressed women, while regression was significantly reduced in all HIV seropositive women except those with the best controlled HIV disease.

Abstract
OBJECTIVE The toxicity and activity of intravenous topotecan were assessed in a multicenter Phase II study (GOG 76-U) in patients with advanced, recurrent, or persistent squamous cell carcinoma of the uterine cervix. METHODS Intravenous topotecan was administered at 1.5 mg/m2 per day for 5 consecutive days every 4 weeks in patients without prior chemotherapy, aside from chemosensitizing agents used in conjunction with radiotherapy. The study required histologic confirmation of primary diagnosis, adequate performance status, and measurable disease to assess response. A two-stage design for accrual was used to allow for early termination of the study should inadequate response or excessive toxicity be an issue. Modifications of dose were based on hematologic toxicity. Treatment was continued until progression of disease was documented or adverse effects prohibited further therapy. RESULTS A total of 49 patients were entered on study: of these 5 were never treated, and 1 was not evaluable for response. More than 88% (38 of 43 patients) had received prior radiotherapy. A median of two courses were administered per patient with a range of 1 to 14 cycles. Grade 4 neutropenia occurred in 68% and grade 4 thrombocytopenia in 18% of patients. Nonhematologic toxic effects were infrequent and not dose-limiting. The overall response rate (complete and partial) was 18.6%. The median progression-free survival was 2.4 months. CONCLUSIONS Topotecan administered at this dose and schedule demonstrated moderate activity albeit at a cost of substantial hematologic toxicity in patients with advanced, recurrent, or persistent squamous cell carcinoma of the cervix.

Abstract
OBJECTIVE The goal of this study was to develop a device which will elevate the small intestine out of the pelvic cavity during radiation after radical surgery. METHODS A prosthetic device of silicone plastic was designed which conforms to the pelvis. This device is filled with saline and renograffin for X-ray visualization. The capacity of the device is between 750 and 1500 cc. A small bowel contrast radiograph is performed prior to radiation to document exclusion from the radiation field. The device remains in place throughout radiation therapy and is then removed through a small incision after draining the contents of the prosthesis. RESULTS Seven devices have been placed to date. The patients' age ranged from 35 to 65 years. All women had stage Ib1 carcinoma of the cervix and all underwent a type III radical hysterectomy with bilateral pelvic and common iliac lymphadenectomy. The indication for placement of the device was deep invasion of tumor in five patients, close margin in one patient, and positive pelvic lymph nodes in one patient. The amount of fluid instilled in the device ranged from 960 to 1200 cc. All patients had a return to normal bowel function within 3 days of surgery. All had radiologically documented exclusion of the small intestine from the radiation field prior to beginning radiation. In the postoperative period there was one major complication: a pulmonary embolism documented by pulmonary angiogram on postoperative day 2. All seven patients completed planned radiotherapy. The devices have been removed, with no adhesions to the prosthesis. CONCLUSIONS The results of this study determine that the feasibility, safety, and efficacy of a prosthetic device in displacing the small bowel from the radiation field following radical surgery are sufficient to warrant a large-scale study. The device should be applicable to any and all tumors that require high dose pelvic radiation. It is expected that displacement of the small intestine from the radiation field will diminish overall complications and may allow delivery of radiation doses that approach colon and bladder tolerance.

Abstract
OBJECTIVE The aim of this study was to determine the response rate and toxicity of cis-platinum and gemcitabine in advanced, recurrent, or persistent squamous cell carcinoma of the cervix. METHODS From July 1997 to January 1999, we conducted a Phase II trial in patients with advanced, persistent, or recurrent carcinoma of the cervix. The schedule employed 1250 mg/m(2) of gemcitabine on days 1 and 8 and 50 mg/m(2) of cis-platinum on day 1 in a 21-day cycle. Eligibility criteria were a GOG performance status of 0-2, adequate bone marrow reserve, serum creatinine less than 1.8 mg%, and a lesion which could be measured in two dimensions. None of the patients had received prior chemotherapy other than radiation sensitizers. Standard GOG toxicity and response criteria were used. RESULTS Nineteen patients were enrolled into the trial. Two patients were inevaluable because of inadequate trial of drug. Seventeen patients were evaluable for response and toxicity. The median age of the patients was 47 years (range 24-72). The median number of cycles delivered was 5 (range 2-8). The incidence of grade 4 neutropenia and anemia was 2.4 and 1.2%, respectively. Two patients developed a single episode of grade 3 gastrointestinal toxicity. The overall response rate was 41% (7/17). There was 1 complete response of 14 months duration and 6 partial responses. Among those patients not previously irradiated, the response rate was 57% (4/7). Among the radiated patients, the response rate was 30% (3/10) with all responses occurring in the radiation field. CONCLUSION This combination of cis-platinum and gemcitabine is a well-tolerated regimen which exhibits high activity in advanced, recurrent, or persistent squamous cell cervical cancer.

Abstract
BACKGROUND Cervical neoplasia occurs with increased frequency among women infected with HIV-1. OBJECTIVE To characterize prevalence of and risk factors for abnormal cervical cytology among women with HIV and to compare them to uninfected women. METHODS Baseline cervical cytology was obtained from 1713 women seropositive for HIV and 482 at-risk control women who were enrolled in the Women's Interagency HIV Study, a multicenter prospective cohort study conducted in six U.S. cities. Associations with sociodemographic, medical, and sexual variables were assessed by Fisher's exact test, Mantel extension test, and logistic regression analysis. RESULTS Cervical cytology was abnormal in 38.3% of HIV-infected women (atypical squamous cells of uncertain significance [ASCUS] 20.9%, low-grade squamous cells of uncertain significance [LSIL] 14.9%, high-grade squamous cells of uncertain significance [HSIL] 2.3%, cancer 0.2%) and 16.2% of HIV-uninfected women (ASCUS 12.7%, LSIL 2.3%, HSIL 1.2%, cancer 0.0%). Risk factors for any abnormal cytology in multivariate analysis included HIV infection, CD4 cell count, HIV RNA level, detection of human papillomavirus (HPV), a prior history of abnormal cytology, employment, and number of male sex partners within 6 months of enrollment. Prior abortion was associated with a decreased risk of cytologic abnormality. CONCLUSIONS Cervical cytologic abnormalities were frequent among women infected with HIV, although high-grade changes were found in only 2.5%. Factors linked to sexual and reproductive history, HPV infection, and HIV disease all influenced risk.

Abstract
OBJECTIVE The objective of this study was to evaluate the benefits and risk of adjuvant pelvic radiotherapy aimed at reducing recurrence in women with Stage IB cervical cancer treated by radical hysterectomy and pelvic lymphadenectomy. METHODS Two hundred seventy-seven eligible patients were entered with at least two of the following risk factors: >1/3 stromal invasion, capillary lymphatic space involvement, and large clinical tumor diameter. Of 277 patients, 137 were randomized to pelvic radiotherapy (RT) and 140 to no further treatment (NFT). RESULTS Twenty-one (15%) in the RT group and 39 (28%) in the NFT group had a cancer recurrence, 18 of whom were vaginal/pelvic in the RT and 27 in the NFT group. In the RT group, of 18 (13%) who died, 15 died of cancer. In the NFT group, of the 30 (21%) who died, 25 died from cancer. Life table analysis indicated a statistically significant (47%) reduction in risk of recurrence (relative risk = 0.53, P = 0.008, one-tail) among the RT group, with recurrence-free rates at 2 years of 88% versus 79% for the RT and NFT groups, respectively. Severe or life-threatening (Gynecologic Oncology Group grade 3 or 4) urologic adverse effects occurred in 4 (3.1%) in the RT group and 2 (1.4%) in the NFT group; 3 (2.3%) and 1 (0.7%) hematologic; 4 (3.1%) and 0 gastrointestinal (GI); and 1 (0.8%) and 0 neurologic, respectively. One patient's death was attributable to grade 4 GI adverse effects. CONCLUSIONS Adjuvant pelvic radiotherapy following radical surgery reduces the number of recurrences in women with Stage IB cervical cancer at the cost of 6% grade 3/4 adverse events versus 2.1% in the NFT group.

Abstract
BACKGROUND Bulky stage IB cervical cancers have a poorer prognosis than smaller stage I cervical cancers. For the Gynecologic Oncology Group, we conducted a trial to determine whether weekly infusions of cisplatin during radiotherapy improve progression-free and overall survival among patients with bulky stage IB cervical cancer. METHODS Women with bulky stage IB cervical cancers (tumor, > or =4 cm in diameter) were randomly assigned to receive radiotherapy alone or in combination with cisplatin (40 mg per square meter of body-surface area once a week for up to six doses; maximal weekly dose, 70 mg), followed in all patients by adjuvant hysterectomy. Women with evidence of lymphadenopathy on computed tomographic scanning or lymphangiography were ineligible unless histologic analysis showed that there was no lymph-node involvement. The cumulative dose of external pelvic and intracavitary radiation was 75 Gy to point A (cervical parametrium) and 55 Gy to point B (pelvic wall). Cisplatin was given during external radiotherapy, and adjuvant hysterectomy was performed three to six weeks later. RESULTS The relative risks of progression of disease and death among the 183 women assigned to receive radiotherapy and chemotherapy with cisplatin, as compared with the 186 women assigned to receive radiotherapy alone, were 0.51 (95 percent confidence interval, 0.34 to 0.75) and 0.54 (95 percent confidence interval, 0.34 to 0.86), respectively. The rates of both progression-free survival (P<0.001) and overall survival (P=0.008) were significantly higher in the combined-therapy group at four years. In the combined-therapy group there were higher frequencies of transient grade 3 (moderate) and grade 4 (severe) adverse hematologic effects (21 percent, vs. 2 percent in the radiotherapy group) and adverse gastrointestinal effects (14 percent vs. 5 percent). CONCLUSIONS Adding weekly infusions of cisplatin to pelvic radiotherapy followed by hysterectomy significantly reduced the risk of disease recurrence and death in women with bulky stage IB cervical cancers.

Abstract
OBJECTIVE The objective of this study was to evaluate the expression of bcl-2, a regulatory protein in programmed cell death, in endometrial hyperplasia before and after progestational therapy. METHODS Pre- and posttreatment paraffin-embedded endometrial tissue samples from 20 women with an initial diagnosis of endometrial hyperplasia were obtained from archived files. Cases were evaluated and classified as either complete resolution of hyperplasia or persistent hyperplasia in response to progestin treatment. Sections were examined for bcl-2, estrogen receptor, and progesterone receptor expression using immunohistochemistry and compared within the treatment response groups. RESULTS Among the 20 women studied, 13 had complete regression of their hyperplasia with progestin treatment and 7 had evidence of persistent disease after therapy. Bcl-2 expression was significantly decreased after treatment from a mean reactivity score of 2.08 to 0.31 (P = 0.0005) in the group of patients whose hyperplasia completely regressed with progestin administration. Among the women who had persistent hyperplasia after therapy, no significant change was observed between pre- and posttreatment bcl-2 expression, with a mean reactivity of 1.86 to 1. 29, respectively (P = 0.075). Progestational therapy significantly decreased the status of estrogen receptors from a mean score of 2.08 to 0.46 (P = 0.0005) in completely resolved cases of hyperplasia and from 2.00 to 0.43 (P = 0.0025) in persistent hyperplasias. Treatment also significantly decreased the status of progesterone receptors from a mean reactivity score of 1.92 to 0.31 (P = 0.0005) in cases of regressed hyperplasia and from a mean reactivity of 1.86 to 0.29 (P = 0.005) in persistent cases of hyperplasia. CONCLUSIONS Bcl-2 expression decreases following successful progestin treatment of endometrial hyperplasias, whereas it remains expressed in hyperplasias which persist despite progestational therapy. This suggests that bcl-2 expression may represent a component of the therapeutic effects exerted in the endometium during progestational therapy in the treatment of hyperplasia. The activity of the oncoprotein may be a potential measure of the progress of treatment.

Abstract
OBJECTIVE Our purpose was to compare the diagnostic ability and treatment efficacy of conization by the loop electrosurgical excision procedure with cold-knife conization. STUDY DESIGN One hundred eighty women who required conization for diagnosis and treatment of cervical dysplasia or microinvasive cervical carcinoma were prospectively enrolled in a randomized clinical trial to receive either cold-knife conization or conization by the loop electrosurgical excision procedure. Conization complications, rate of lesion clearance, and therapeutic outcome were assessed for the 2 study groups. RESULTS There were no statistically significant differences in the complication rate (P = 1.00), the rate of lesion clearance (P =.18), or the rate of disease recurrence (P =.13) between the 2 study groups. The mean follow-up was 11.2 months in the cold-knife conization group and 10.4 months in the loop-excision conization group. CONCLUSION Cold-knife conization and loop-excision conization yield similar diagnostic and therapeutic results.

Abstract
OBJECTIVE The aim of this study was to test the hypothesis that DNA methylation is important for silencing the p16 tumor suppressor gene in ovarian epithelial tumors and to compare the prevalence of this mechanism among different ovarian epithelial tumor subtypes. METHOD Methylation-specific PCR was used to analyze the p16 gene for DNA methylation in 20 ovarian cystadenomas, 15 low malignant potential (LMP) tumors, and 37 carcinomas. p16 expression was determined immunohistochemically in 58 of these tumors (16 cystadenomas, 13 LMP tumors, 29 carcinomas). Differences in methylation or expression rates between specific tumor subgroups were examined by Fisher's exact test. RESULTS Fragments from the distal promoter and beginning of the first exon of the p16 gene were both methylated in 5 of 15 (33%) LMP tumors compared to 2 of 37 (5%) carcinomas (P = 0. 02). Those sites were also methylated in 5 of 20 (25%) cystadenomas. Lack of p16 expression was present in 7 of 16 cystadenomas, 4 of 13 LMP tumors, and 22 of 29 carcinomas (P [LMPs versus carcinomas] = 0. 01) and correlated with methylation changes in LMP tumors (P = 0.05). p16 expression was correlated with mucinous differentiation in cystadenomas (P = 0.001). CONCLUSION p16 silencing may be important for the development of ovarian carcinomas and a subset of LMP tumors. Changes in DNA methylation may be more important for inactivation of this gene (and perhaps other tumor suppressor genes) in LMP tumors, which lack many of the alternative mechanisms present in carcinomas. p16 expression is primarily related to mucinous differentiation in cystadenomas.

Abstract
OBJECTIVE To determine the usefulness of serum carcinoembryonic antigen (CEA) determination in predicting the nature of an isolated pelvic mass. STUDY DESIGN Two hundred twenty-six women with an isolated pelvic mass had a serum CEA determination preoperatively. The results were correlated with the histopathologic findings. RESULTS CEA was elevated in 19 of the 226 women. Twelve of the 183 (7%) women with benign masses, 2 of the 17 (12%) women with tumors of low malignant potential and 5 of the 15 (33%) women with a frankly invasive epithelial ovarian cancer had elevated CEA. None of the women with a malignant germ cell or stromal tumor had elevated CEA (P = .06 for prediction of malignancy.) There were no cases of metastatic gastrointestinal malignancies in the study group. The sensitivity, specificity, positive predictive value and negative predictive value of serum CEA were 16%, 93%, 37% and 83%, respectively. The corresponding figures for serum CA-125 were 67%, 71%, 35% and 90%. There was no statistically significant correlation between elevated CEA and mucinous histology. CONCLUSION Preoperative serum CEA determination in women with isolated pelvic masses is not useful.

Abstract
OBJECTIVE To determine if the quantity of lymph-vascular space invasion influences the risk of pelvic nodal metastases in women with early-stage cervical squamous carcinoma. METHODS Between 1991 and 1997, 105 women with stages IA2, Ib, and IIa squamous carcinoma of the cervix underwent radical hysterectomy and pelvic lymphadenectomy. The histopathology slides were prospectively reviewed. If lymph-vascular space invasion (LVSI) was present, the amount was quantified in four ways: percentage of cervical histopathologic sections containing LVSI, percentage of sections with tumor containing LVSI, total number of foci of LVSI, and maximal number of foci of LVSI in 10 high-powered fields. These measures of LVSI were correlated with the risk of nodal metastases. RESULTS Seventy-three (70%) women had tumors with LVSI. Of these, 23 had pelvic nodal metastases. All women with nodal metastases had tumors with LVSI. Using logistic regession, independent predictors of nodal metastases were depth of cervical stromal invasion (P = 0.01) and tumor size (P = 0.04). LVSI was also a significant predictor of nodal metastases based on the Mantel-Haenszel test (P = 0.01). In women whose tumors contained LVSI, logistic regression identified tumor size (P = 0.004) and LVSI in > 45% of all cervical histopathologic sections (P = 0.002) as significant predictors of nodal metastases. CONCLUSION The quantity of LVSI, as defined by the percentage of all cervical histopathologic sections containing LVSI, correlates significantly with the risk of nodal metastases in women with early-stage squamous carcinoma of the cervix.

Abstract
BACKGROUND Telomerase is an enzyme essential for the normal replication of chromosomes. Telomerase activity is absent in most somatic cells in adults, but it is usually expressed in cancer cells, including ovarian carcinoma cells. Our principal goal was to compare the sensitivity of a telomerase assay, i.e., the telomeric repeat amplification protocol (TRAP) assay, with that of cytologic examination in detecting cancer cells in the peritoneal cavity of patients with ovarian carcinoma. METHODS TRAP assays and cytologic examinations were performed on peritoneal washings and ascitic fluids from 42 patients with active ovarian carcinoma. Control specimens included washings from 29 patients with benign ovarian diseases and ascitic fluids from 14 patients with liver failure. We also evaluated the stability of telomerase in ascitic fluids left unprocessed at room temperature as well as the ability of the TRAP assay to detect cancer cells in mixtures containing large numbers of normal cells. RESULTS Specimens from 37 (88%) of the 42 patients with ovarian carcinoma tested positive for telomerase. Cytologic examination detected cancer cells in only 27 of the telomerase-positive specimens (i.e., in specimens from 64% of the 42 patients). This difference of 24% (95% confidence interval = 17%-30%) in sensitivity between the two tests was statistically significant (two-sided P = .002). Specimens from five of the patients with ovarian carcinoma were cytologically negative and telomerase negative. All 43 control specimens were cytologically negative, but the TRAP assay detected telomerase in two of them. Telomerase activity was detected in unprocessed samples left at room temperature for 5 days and in mixtures containing a small number of cancer cells and a 2000- to 10000-fold excess of normal cells. CONCLUSIONS Assaying for telomerase is more sensitive than cytologic examination in detecting cancer cells in the peritoneal cavity of patients with ovarian carcinoma.

Abstract
OBJECTIVE To quantify the risk of residual invasion when cervical conization reveals microinvasive squamous carcinoma and to determine whether any factors affect this risk. METHODS We reviewed the charts and histopathology slides of 87 women who underwent a conization that contained microinvasive squamous carcinoma, followed by either a repeat conization or hysterectomy. Depth of invasion, number of invasive foci, and status of the internal margin and post-conization endocervical curettage (ECC) were assessed. The findings were correlated with the presence of residual invasion. RESULTS Significant predictors of residual invasion included status of the internal margin (residual invasion present in 22% of women with an involved margin versus 3% with a negative margin; P < .03) and the combined status of the internal margin and post-conization ECC (residual invasion in 4% of patients if both negative, 13% if one positive, and 33% if both positive; P < .015). Depth of invasion and number of invasive foci in the conization specimen were not significant. The power of this study to detect a 25% difference in the risk of residual invasion was 73% for depth of invasion and 75% for number of invasive foci. CONCLUSION Women with microinvasive squamous carcinoma in a conization specimen in which both the internal conization margin and post-conization ECC are negative have a low risk of residual invasion and are candidates for follow-up or simple hysterectomy. If either the internal margin or the post-conization ECC contains dysplasia or carcinoma, the risk of residual invasion is high and warrants repeat conization before definitive treatment planning.

Abstract
Radiation therapy is the mainstay in treatment of locally advanced cervical carcinoma. Several chemotherapeutic agents have been used as radiation sensitizers in the treatment of cervical cancer in an effort to improve local response and survival. A prospective study was designed to evaluate carboplatin as a radiosensitizer in advanced cervical cancer. Standard radiotherapy techniques were used to treat patients with Stage IIA-IIIB cervical cancer. Intravenous carboplatin was administered twice weekly concurrent with external beam radiation. Of 22 evaluable patients, there were 19 complete responders of whom 15 remain alive: 11 patients were alive and disease free at last visit for a median duration of 15 months follow-up (range, 4-43 months) and 4 patients remain alive with disease for a median duration of 17 months (range, 3-55 months). Seven have died, one of whom was without evidence of disease. There were no treatment-related deaths and no grade 4 toxicity. The most significant adverse effect was hematologic resulting in four patients with grade 3 neutropenia or anemia. There were no fistulae or late gastrointestinal or genitourinary complications. This pilot study suggests that carboplatin administered with standard radiation is safe, well-tolerated, and thus may be useful as a radiation sensitizer in the treatment of locally advanced cervical cancer.

Abstract
OBJECTIVE To determine the ability of pelvic examination, tumor marker assessment, and transvaginal ultrasonography, with selected use of Doppler ultrasonography, to predict pelvic malignancy. METHODS Two hundred twenty-six women scheduled for operative removal of a pelvic mass were entered in the study prospectively. Each woman underwent pelvic examination, tumor marker assessment, and transvaginal ultrasonography preoperatively. Women whose gray-scale findings were suspicious for malignancy underwent Doppler ultrasonography. Suspicious findings included masses that were fixed or irregular on pelvic examination; CA 125 level greater than 35 U/mL; elevations in serum lactic dehydrogenase, alpha-fetoprotein, or hCG; and the presence of a substantial solid component on gray-scale ultrasonography. Suspicious Doppler findings included intratumoral color flow, pulsatility index less than 1.0, or resistance index 0.4 or lower. The findings were correlated with the presence of malignancy. RESULTS If all three indicators (examination, tumor marker assessment, and gray-scale ultrasound findings) were nonsuspicious, 99% of premenopausal women and 100% of postmenopausal women had benign masses. If all three indicators were suspicious, 77% of premenopausal women and 83% of postmenopausal women had malignant tumors. Logistic regression identified ultrasound impression and tumor size to be significant predictors of malignancy in premenopausal women, whereas CA 125 level and ultrasound impression were significant in postmenopausal women. In patients with suspicious gray-scale findings, recategorization based on Doppler findings resulted in inferior diagnostic indices. CONCLUSIONS Ultrasonographic tumor size and appearance are the best predictors of pelvic malignancy in premenopausal women, whereas CA 125 level and ultrasonographic appearance are the best predictors in postmenopausal women. Neither color nor spectral Doppler is useful in this setting.

Abstract
Sixty-one patients with FIGO IB cervical cancer treated with planned preoperative radiotherapy (dose to point A: 52-93 Gy, mean 73 Gy) and hysterectomy from 1969 to 1993 were retrospectively reviewed. Patient characteristics and treatment parameters and their association with residual tumor in the hysterectomy specimen were analyzed. Glandular (adenocarcinoma and adenosquamous) tumors were smaller than squamous tumors: 6/11 (55%) were < 6 cm in diameter, versus 12/50 (24%) squamous tumors (p = 0.03). Glandular tumors had a higher incidence of residual disease: 10/11 (91%) versus 24/50 (48%) (p = 0.01). There was no association between presence of pathologic residual disease in the hysterectomy specimen and tumor size, morphology (endophytic vs. exophytic), patient age, dose to point A, time to deliver radiotherapy, or interval between radiotherapy and hysterectomy. Overall 34/61 (56%) patients had residual disease in their hysterectomy specimens after planned preoperative radiotherapy. There were significantly more glandular tumors than squamous tumors with residual disease, even though glandular tumors were a group of smaller tumors.
