RESUMO

BACKGROUND: This Phase 2b study compared the efficacy and toxicity of belotecan and topotecan in recurrent ovarian cancer. METHODS: Patients with platinum-sensitive recurrent or platinum-resistant recurrent ovarian cancer (PRROC) were randomised 1:1 to receive belotecan 0.5 mg/m2 or topotecan 1.5 mg/m2 for five consecutive days every 3 weeks. The primary endpoint was overall response rate (ORR); secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity. RESULTS: A total of 140 (belotecan, n = 71; topotecan, n = 69) and 130 patients (belotecan, n = 66; topotecan, n = 64) were included in the intention-to-treat (ITT) and per-protocol (PP) populations. ORR did not differ significantly between the belotecan and topotecan groups (ITT, 29.6% versus 26.1%; PP, 30.3% versus 25%). Although PFS did not differ between the groups, belotecan was associated with improved OS compared with topotecan in the PP population (39.7 versus 26.6 months; P = 0.034). In particular, belotecan showed longer OS in PRROC and non-high-grade serous carcinoma (non-HGSC; PP, adjusted hazard ratios, 0.499 and 0.187; 95% confidence intervals 0.255-0.977 and 0.039-0.895). Furthermore, there were no differences in toxicities between the two groups. CONCLUSIONS: Belotecan was not inferior to topotecan in terms of overall response for recurrent ovarian cancer. CLINICAL TRIAL REGISTRATION: NCT01630018.

RESUMO

OBJECTIVE: This study aimed to investigate current clinical management of leiomyosarcoma (LMS) in Korea. MATERIALS AND METHODS: We conducted a Web-based survey among members of the Korean Gynecologic Oncology Group regarding their treatment of LMS. RESULTS: In total, 77 (27.8%) of 277 members responded to the survey. For surgical treatment of stage I LMS, 26.8% indicated total hysterectomy only and 16.9% indicated total hysterectomy with bilateral salpingo-oophorectomy. Also, lymph node dissection was indicated by 54.9% of respondents, whereas 46.5% stated that bilateral salpingo-oophorectomy could be omitted in young patients. More than half (57.7%) of the respondents recommended against adjuvant treatment. For stage I LMS diagnosed after morcellation, 79.2% of the respondents recommended lymph node dissection and 56.4% recommended adjuvant therapy. As for advanced-stage LMS, in cases of complete resection, adjuvant chemotherapy was preferred by 63.1%. For incomplete resection, combined radiotherapy/chemotherapy was the most preferred adjuvant therapy (63.1%). CONCLUSIONS: Among Korean Gynecologic Oncology Group members, there are many discrepancies in the clinical management of LMS. A large-scale prospective study to establish treatment guidelines is needed.

RESUMO

OBJECTIVE: The objectives were to evaluate the risk of malignant adnexal tumors in women with nongynecologic malignancies and to identify variables associated with the risk of malignant adnexal tumors. METHODS: The eligibility criteria included the diagnosis of a nongynecologic malignancy and adnexal tumors, which were resected or subjected to biopsy at our institute between 1999 and 2010. The risk of malignant adnexal tumors was assessed by dividing the number of patients with metastatic tumors to the adnexa or primary adnexal cancers by the total number of patients. The association of clinicopathologic variables with the risk of malignant adnexal tumors was evaluated using the Fisher exact test and binary logistic regression analysis. In patients with metastatic tumors to the adnexa, the association of clinicopathologic variables with overall survival after adnexal surgery was examined using the log-rank test. RESULTS: In 166 patients with adnexal tumors, 41 benign tumors, 113 metastatic tumors to the adnexa, and 12 primary adnexal cancers were diagnosed. Age older than 46 years, a tumor type associated with a high risk for malignant adnexal tumors, and bilateral tumors significantly increased the risk of malignant adnexal tumors. The overall survival of the patients with stomach cancer was significantly worse than the patients with colorectal or breast cancers. CONCLUSION: One hundred twenty-five of the 166 patients with nongynecologic malignancies who had adnexal tumors managed surgically were shown to have malignant tumors, and most of the tumors were metastatic from primary sites. The risk of malignant adnexal tumors was associated with age, nongynecologic malignancy, and bilaterality.

RESUMO

BACKGROUND/AIMS: We examined the association of fibrin sealant use with post-operative hemorrhage in patients who underwent a loop electrosurgical excision procedure (LEEP). METHODS: We retrospectively collected clinicopathologic data of 344 patients who underwent LEEP at our institute between 2007 and 2009. We defined hemorrhage which occurred between 1 and 30 days after LEEP and required electrocautery to achieve hemostasis as severe secondary hemorrhage (SSH). We determined whether or not the use of fibrin sealant during LEEP was associated with a decreased occurrence of SSH. In addition, we examined the associations of other clinicopathologic variables with SSH and fibrin sealant use. RESULTS: SSH occurred in 6 of 200 patients (3%) with fibrin sealant and in 12 of 144 patients (8%) without fibrin sealant. Based on univariate analysis, the use of fibrin sealant was associated with SSH (p = 0.028). However, age, surgeons and pathologic diagnosis were not associated with SSH. Based on multivariate analysis, the use of fibrin sealant was associated with less SSH (p = 0.033, OR = 0.328, 95% CI 0.117-0.917). CONCLUSION: Fibrin sealant use reduces the incidence of severe post-operative hemorrhage after LEEP.

RESUMO

OBJECTIVE: To investigate if a self-obtained vaginal sample (SOVAS) contains sufficient DNA for a human papillomavirus (HPV) test and if the results are comparable to those obtained via cervical samples (CS) collected by a physician. METHODS: One hundred and fifty-one women who had abnormal cervical smears or who were HPV-positive were enrolled. Self-sampling was done after reading instructions and watching a 2-min-long video, whereas CS was obtained with a cervical cytobrush during a gynecologic examination. RESULTS: A multiplex real-time polymerase chain reaction-based assay detected the prevalence of any type of HPV to be 67.5% in the SOVAS and 57.4% in the CS, and that of high-risk (HR-) HPV to be 58.7% in the SOVAS and 48.6% in the CS. The sensitivity of detection of HR-HPV in the SOVAS was 100% (95% confidence interval [CI] -0.09 to 0.32) for high-grade squamous intraepithelial lesion, 78% (95% CI -0.09 to 0.13) for atypical squamous cells of undetermined significance or worse, and 95% (95% CI -0.01 to 0.25) for low-grade squamous intraepithelial lesion or worse, which was statistically within the non-inferiority margin compared with that of CS. CONCLUSION: Our study shows that the collection of a SOVAS is feasible and it is comparable to a CS for HPV DNA testing. Future studies are required to investigate the feasibility and cost-effectiveness of a mail-delivered SOVAS for cervical cancer screening.

RESUMO

This study assessed the feasibility of F-18-fluorodeoxyglucose positron-emission tomography ((18)F-FDG PET) in the post-therapy surveillance for patients with endometrial cancer showing no evidence of disease (NED). From April 1997 to June 2007, 127 patients with endometrial cancer showing NED were performed (18)F-FDG PET scan. The feasibility of (18)F-FDG PET for the early detection of recurrence in patients with endometrial cancer was evaluated retrospectively. Of the 127 patients, 32 patients showed positive lesions on (18)F-FDG PET scan. Nineteen (19/127 cases, 15%) of them were confirmed to have a recurrence clinically or histologically. The sensitivity, specificity and positive and negative predictive value of (18)F-FDG PET for detecting recurrences in patients with endometrial cancer were 100%, 88%, 59% and 100%, respectively. In conclusion, (18)F-FDG PET may be a useful method for the post-therapy surveillance in patients with endometrial cancer.

RESUMO

We experienced an extremely rare case of proximal epithelioid sarcoma (PES) of the vulva in a 77-year-old woman. After history taking and physical examination, the patient was tentatively diagnosed as having Bartholin's cyst in the right labium. Based on histopathological and immunohistochemical (IHC) findings, however, a final diagnosis of PES of the vulva was made. After receiving CyberKnife treatment, the patient survived but with recurrent episodes and poor prognosis. In conclusion, our case indicates that patients with PES of the vulva should be appropriately managed with radiotherapy after a differential diagnosis based on histopathological and IHC findings.

RESUMO

OBJECTIVE: This study aimed to evaluate the prognostic impact of age at diagnosis, and pretreatment hematologic markers, including lymphocyte percentage and the neutrophil-to-lymphocyte ratio (NLR), in patients with locally advanced cervical cancer (LACC) treated with definitive radiotherapy (RT). METHODS: A total of 392 patients with LACC (stage IIb to IVa) treated with cisplatin-based concurrent chemoradiotherapy or RT alone between 2001 and 2012 were retrospectively enrolled. Clinical data and pretreatment complete blood counts were extracted from electronic medical records of the patients, and analyzed. Treatment outcomes, progression-free survival (PFS), and overall survival (OS) were evaluated. RESULTS: Low lymphocyte percentage and a high NLR were associated with younger age, advanced stage, larger tumor size, lymph nodes metastasis, and treatment failure. The cut-off value for lymphocyte percentage and NLR was determined using a receiver operating characteristic curve. In univariate analysis, low lymphocyte percentage (≤24%) was associated with poor PFS and OS, while high NLR (>2.8) was significantly associated only with PFS. In multivariate analysis, both lymphocyte percentage (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.40-0.85; P=0.005) and NLR (HR, 1.55; 95% CI, 1.07-2.25; P=0.022) had independent prognostic value for PFS. Compared to younger patients (age ≤50 years), older patients (age >60 years) had a lower risk of death. CONCLUSION: Although the lymphocyte percentage did not remain significant in multivariate analysis for OS, it was predictive of PFS and OS. Thus, lymphocyte percentage is a simple hematologic parameter with a significant prognostic value in patients with LACC treated with definitive RT.

RESUMO

PURPOSE: The clinical characteristics and outcomes of patients with metastatic recurrent cervical cancer remain poorly understood. The goals of the present study were to investigate the survival outcomes according to the recurrence site in a large cohort of cervical cancer patients. METHODS AND MATERIALS: Of 1322 patients with primary cervical cancer from 2000 to 2013, 205 with recurrence after primary or adjuvant postoperative radiation were enrolled retrospectively. Aggressive salvage therapy (AST), which was defined as salvage therapy that aimed not only to relieve symptoms but also to ablate recurrent tumors by the single or combined application of surgical resection of local recurrence, metastasectomy, or metastasis-directed irradiation, followed by chemotherapy, was performed according to our institutional guidelines. The patterns of recurrence, application rate and mode of AST, and survival outcomes were evaluated retrospectively under approval from the institutional review board. RESULTS: Regarding the pattern of recurrence, distant-only (DO) recurrence was most common (59.5%), followed by combined (21.5%), central (cervix or vaginal stump; 10.7%), and pelvic (pelvic lymph nodes or pelvic side wall; 8.3%) recurrence. Two subgroups (distant lymph nodes and lung parenchyma) of the DO group demonstrated remarkably good prognosis and were categorized as type A DO; the other subgroups were labeled type B DO. Patients with type A DO recurrence constituted 36% of all recurrences and 83.8% of them received AST. The 5-year overall survival rates were significantly greater in the type A DO group than in the other groups (44.8% in the type A DO group, 12.6% in the pelvic group, and 6.8% in the type B DO group). CONCLUSIONS: We identified a patient subgroup with favorable outcomes after salvage therapy, type A DO, defined as recurrence in the distant lymph nodes only or in the lung parenchyma only. A future prospective trial is needed to investigate whether AST improves survival in this group.

RESUMO

Preoperative identification of individuals at low risk of lymph node metastasis is key to the proper management of endometrial cancer. This study evaluated the role of preoperative assessment based on magnetic resonance imaging (MRI) and histological analysis in identifying a group having a low risk of lymph node metastasis. Data of 529 patients with endometrial cancer were obtained from a prospective multicenter database, between January 2012 and December 2014. Clinical staging, based on MRI and histological analysis, was compared with final pathology results after the surgical staging procedure. The preoperative low-risk criteria, based on current guidelines from Korea, France, and Canada, and criteria used for fertility-sparing therapies, were applied to our multicenter cohort and the accuracy of each set of criteria for identifying group at low risk of lymph node metastasis was evaluated. When considering grades or MR stages separately, the overall agreement between preoperative and postoperative findings was poor (Kappa 0.45 for grades; 0.41 for stages). However, when combining these two parameters, the low-risk group, as defined by any of the guidelines, had an acceptable rate of lymph node metastasis (below 3%). The French guidelines identified 249 patients (47.1%) as being in the low-risk group. Criteria used to define fertility-sparing therapy candidates identified 48 patients (9.1%) among the study population, only one of whom had extra-uterine disease. This study shows that the current guidelines, using preoperative assessment based on MRI and histological analysis, can identify low-risk patients, who may be candidates for omitting lymphadenectomy.

RESUMO

AIMS: To determine the feasibility of stereotactic body radiotherapy (SBRT) in patients with pelvic sidewall recurrence of uterine cervical cancer after radical hysterectomy or definitive radiotherapy. METHODS: We retrospectively reviewed 23 patients with locally recurrent uterine cervical cancer limited to the pelvic sidewall who were treated with SBRT at our institution between January 2003 and May 2010. The SBRT dose ranged from 27 to 45 Gy (median, 39 Gy) in three fractions, and the fractional SBRT dose ranged from 9 to 15 Gy (median, 13 Gy). RESULTS: The 2-year overall survival, local progression-free survival and disease progression-free survival rates were 43%, 65% and 52%, respectively. Patients with small tumors (gross tumor volume <30 cm(3) ) had a significantly longer 2-year overall survival rate and 2-year local progression-free survival rate than did patients with large tumors (overall survival rate: 89% vs 12%; P = 0.0001 and local progression-free survival: 85% vs 0%; P = 0.0199). There were three cases (13%) of severe toxicities (rectovaginal fistula). Pelvic pain relief was achieved in all patients. In particular, 10 of 14 patients (71%) achieved analgesic (nonsteroidal anti-inflammatory drug or narcotic) reduction of 50% or more from baseline. CONCLUSION: SBRT is a feasible treatment option for women with pelvic sidewall tumors from recurrent uterine cervical cancer, especially for small recurrent tumors. However, SBRT should be used carefully in the treatment of large tumors, as the incidence of severe late toxicity increases with the size of the tumor.

RESUMO

OBJECTIVE: Considering the increased use of [(18)F]FDG PET or PET/CT, the clinical significance of thyroid incidentalomas is the subject of controversy. The aim of this study was to determine the incidence of malignancies associated with thyroid incidentalomas detected by pre-treatment PET or PET/CT in patients with cervical cancer. METHODS: We retrospectively reviewed the medical records of patients with cervical cancer who had thyroid incidentalomas detected by pre-treatment PET or PET/CT and were treated at our institute between January 2001 and December 2009. RESULTS: Of 327 patients who underwent pre-treatment PET or PET/CT, 33 patients had thyroid incidentalomas (10.1%) and 4 patients were diagnosed with thyroid malignancies by percutaneous needle aspiration (PCNA) or surgery. To put it concretely, of 33 patients with thyroid incidentaloma, 16 patients had a diffuse uptake and 17 patients had a focal uptake. Four of 17 patients with focal uptake were diagnosed with thyroid malignancies (23.5%). One patient with a focal uptake had an atypical cell based on PCNA, but did not undergo additional studies. The mean SUV(max) of thyroid malignancies did not differ from that of benign thyroid diseases. CONCLUSION: Thyroid incidentalomas are frequently detected by pre-treatment PET or PET/CT in patients with cervical cancer. Focal uptake on PET or PET/CT has a high risk of thyroid cancer.

RESUMO

OBJECTIVE: Locally advanced bulky cervical cancer (LABCC) is characterized by poor local control. The objective of this study was to identify the clinicopathologic variables associated with one-year central-only recurrence, which will serve as criteria for adjuvant hysterectomy after radiation (AHR) in patients with LABCC. STUDY DESIGN: Between January 2000 and August 2007, we retrospectively evaluated outcomes in 225 patients with LABCC who were initially treated with radiation or chemoradiation. RESULTS: Among the 225 patients with LABCC, there were 41 recurrences within one year after treatment (8 central-only and 33 pelvis and/or distant site recurrences). Age, stage, and treatment type were not associated with the one-year central-only recurrences, but tumor size ≥8cm had a statistically significant association based on multivariate analysis (OR, 5.39; 95% CI, 1.15-25.31; p=0.03). The combination of non-squamous cell (non-SCC) type and tumor size ≥8cm had a significantly higher rate of recurrence within one year (OR, 43.0; 95% CI, 4.78-386.68; p<0.01). CONCLUSIONS: Of patients with LABCC, those with non-SCC tumors ≥8cm in size were at high risk for early central-only recurrence after cisplatin-based chemoradiation, and represent the subset of patients for whom AHR is beneficial.

RESUMO

OBJECTIVE: Little is known about the guideline adherence of nurses to chemotherapy administration guidelines. We determined the guideline adherence of nurses to the Chemotherapy Administration Safety Standards and the relationship between demographic characteristics and guideline adherence. METHODS: Survey sheets containing two questions on demographic characteristics and 16 questions on the guideline adherence of nurses regarding chemotherapy administration were distributed to all in-patient departments in our hospital in which chemotherapy was performed. All clinical nurses in the department were recommended to respond. RESULTS: Of 202 nurses, 123 responses were collected (61% response rate). The guideline adherence rate was >70% for 15 of 16 questions, but 55% of respondents indicated that there was no competency monitoring for nurses. Nurses with >7 years of clinical nursing experience felt more competent in performing cardiopulmonary resuscitation (CPR) than nurses with <7 years of clinical nursing experience (p=0.032). CONCLUSION: The guideline adherence rate of nurses with respect to chemotherapy administration was high, with the exception of the absence of a competency monitoring for nurses. A significant number of nurses with <7 years of clinical nursing experience felt incompetent in performing CPR.

RESUMO

PURPOSE: To determine whether adjuvant chemoradiotherapy (CRT) improves the outcome of cervical cancer patients with intermediate risk factors. METHODS AND MATERIALS: Between January 2000 and June 2006, the medical records of 735 patients who had undergone radical surgery for Stage IB-IIA cervical cancer were reviewed retrospectively. Of the 735 patients, 172 with two or more intermediate risk factors (i.e., lymphovascular space involvement, deep stromal invasion, and tumor size≥2 cm) were grouped as follows according to the adjuvant treatment received: 34 patients, no further treatment; 49 patients, RT; and 89 patients, CRT. The significance of the clinical parameters and recurrence-free survival of each group were analyzed. RESULTS: Of the 172 patients with any of the intermediate risk factors, 137 (79.6%) had two or more intermediate risk factors. Of the 172 patients, 12 developed recurrences (6.4%)->(7.0%), with 6 in the pelvis and 6 in distant sites. All 12 recurrences occurred in those who had two or more intermediate risk factors (sensitivity, 100%); however, only six recurrences were detected in patients who met the Gynecologic Oncology Group criteria for the intermediate-risk group (sensitivity, 50%; Z test, p<.05). A statistically significant difference was found in the 3-year recurrence-free survival rate among the no further treatment, RT, and CRT groups (67.5%, 90.5%, and 97.5%, respectively; p<.05). The incidence of Grade 3-4 hematologic and gastrointestinal toxicities was not significantly different statistically between the RT and CRT groups (6.1% and 13.4%, respectively; p > .05). CONCLUSION: Postoperative adjuvant CRT can improve the outcome of cervical cancer patients with intermediate risk factors, with low increase in toxicity.

RESUMO

PURPOSE: To compare compliance, toxicity, and outcome of weekly and triweekly cisplatin administration concurrent with radiotherapy in locally advanced cervical cancer. METHODS AND MATERIALS: In this open-label, randomized trial, 104 patients with histologically proven Stage IIB-IVA cervical cancer were randomly assigned by a computer-generated procedure to weekly (weekly cisplatin 40 mg/m(2), six cycles) and triweekly (cisplatin 75 mg/m(2) every 3 weeks, three cycles) chemotherapy arms during concurrent radiotherapy. The difference of compliance and the toxicity profiles between the two arms were investigated, and the overall survival rate was analyzed after 5 years. RESULTS: All patients tolerated both treatments very well, with a high completion rate of scheduled chemotherapy cycles. There was no statistically significant difference in compliance between the two arms (86.3% in the weekly arm, 92.5% in the triweekly arm, p > 0.05). Grade 3-4 neutropenia was more frequent in the weekly arm (39.2%) than in the triweekly arm (22.6%) (p = 0.03). The overall 5-year survival rate was significantly higher in the triweekly arm (88.7%) than in the weekly arm (66.5%) (hazard ratio 0.375; 95% confidence interval 0.154-0.914; p = 0.03). CONCLUSIONS: Triweekly cisplatin 75-mg/m(2) chemotherapy concurrent with radiotherapy is more effective and feasible than the conventional weekly cisplatin 40-mg/m(2) regimen and may be a strong candidate for the optimal cisplatin dose and dosing schedule in the treatment of locally advanced cervical cancer.

RESUMO

PURPOSE: The purpose of this study was to develop a nomogram capable of predicting the probability of 5-year survival after radical radiotherapy (RT) without chemotherapy for uterine cervical cancer. METHODS AND MATERIALS: We retrospectively analyzed 549 patients that underwent radical RT for uterine cervical cancer between March 1994 and April 2002 at our institution. Multivariate analysis using Cox proportional hazards regression was performed and this Cox model was used as the basis for the devised nomogram. The model was internally validated for discrimination and calibration by bootstrap resampling. RESULTS: By multivariate regression analysis, the model showed that age, hemoglobin level before RT, Fédération Internationale de Gynécologie Obstétrique (FIGO) stage, maximal tumor diameter, lymph node status, and RT dose at Point A significantly predicted overall survival. The survival prediction model demonstrated good calibration and discrimination. The bootstrap-corrected concordance index was 0.67. The predictive ability of the nomogram proved to be superior to FIGO stage (p=0.01). CONCLUSIONS: The devised nomogram offers a significantly better level of discrimination than the FIGO staging system. In particular, it improves predictions of survival probability and could be useful for counseling patients, choosing treatment modalities and schedules, and designing clinical trials. However, before this nomogram is used clinically, it should be externally validated.

RESUMO

OBJECTIVE: THE OBJECTIVES OF THIS STUDY WERE TWOFOLD: to verify whether the type of metastasis (lymphatic vs. hematogenous) is a prognostic factor, and to identify molecular markers associated with survival in patients with disseminated cervical cancer. METHODS: Between April 1997 and May 2008, 30 patients with disseminated cervical cancer who had supraclavicular lymph node (N=13) or hematogenous metastases (N=17) were initially treated at our institute. We reviewed medical records to extract clinicopathologic variables. For 17 patients with available pathological specimens, we evaluated the association of immunohistochemical staining for metalloproteinase (MMP)-2, vascular endothelial growth factor (VEGF)-A, and laminin V gamma (LAMC)-2 with survival and clinicopathologic variables via a log-rank test and Cox regression analysis. RESULTS: Patients who had only lymphatic metastasis (odds ratio [OR], 5.3; 95% confidence interval [CI], 1.4 to 19.5) or completed initial treatment (OR, 3.2; 95% CI, 1.1 to 9.9) showed better survival than patients who did not, but none of the molecular markers were associated with survival. Out of 13 patients with only lymphatic metastasis, three patients who had received volume-directed radiation with concurrent chemotherapy had a long-term survival of over two years. However, patients with hematogenous metastasis showed extremely poor prognosis. CONCLUSION: The type of metastasis and completion of initial treatment were associated with prolonged survival in patients with disseminated cervical cancer, and over 20% of patients with lymphatic metastasis were salvaged with volume-directed radiation with concurrent chemotherapy. None of the molecular markers were associated with survival in patients with disseminated cervical cancer.

RESUMO

PURPOSE: The aims of this study were to evaluate the role of stereotactic body radiation therapy (SBRT) as a local treatment for isolated para-aortic lymph node (PALN) metastases originating from uterine cervical and corpus cancer. METHODS AND MATERIALS: We retrospectively enrolled 30 patients with isolated PALN metastases originating from uterine cervical and corpus cancer who had received SBRT using the CyberKnife (CK). All patients were shown to have isolated PALN metastases by computed tomography (CT) and/or positron emission tomography (PET)-CT. The overall survival (OS), local control (LC) rate, and disease progression-free survival (DPFS) rate were calculated according to the Kaplan-Meier method. Comparison between prognosis groups was performed using log-rank analysis. Toxicities were also evaluated. RESULTS: The 4-year OS rate was 50.1%, and the median survival time was not reached. The OS rate among symptomatic patients was significantly lower than that among asymptomatic patients (p = 0.002). The 4-year actuarial LC rate was 67.4%. Patients with a planning target volume of
