RESUMEN

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.

RESUMEN

PURPOSE: A phase II study (ClinicalTrials.gov identifier: NCT00628251) showed activity of olaparib capsules versus pegylated liposomal doxorubicin in patients with germline BRCA-mutated platinum-resistant or partially platinum-sensitive relapsed ovarian cancer. We conducted a phase III trial (SOLO3) of olaparib tablets versus nonplatinum chemotherapy in patients with germline BRCA-mutated platinum-sensitive relapsed ovarian cancer who had received at least 2 prior lines of platinum-based chemotherapy. PATIENTS AND METHODS: In this randomized, open-label trial, patients were randomly assigned 2:1 to olaparib 300 mg twice a day or physician's choice single-agent nonplatinum chemotherapy (pegylated liposomal doxorubicin, paclitaxel, gemcitabine, or topotecan). The primary end point was objective response rate (ORR) in the measurable disease analysis set assessed by blinded independent central review (BICR). The key secondary end point was progression-free survival (PFS) assessed by BICR in the intent-to-treat population. RESULTS: Of 266 randomly assigned patients, 178 were assigned to olaparib and 88 to chemotherapy. In patients with measurable disease (olaparib, n = 151; chemotherapy, n = 72), the BICR-assessed ORR was significantly higher with olaparib than with chemotherapy (72.2% v 51.4%; odds ratio [OR], 2.53 [95% CI, 1.40 to 4.58]; P = .002). In the subgroup who had received 2 prior lines of treatment, the ORR was 84.6% with olaparib and 61.5% with chemotherapy (OR, 3.44 [95% CI, 1.42 to 8.54]). BICR-assessed PFS also significantly favored olaparib versus chemotherapy (hazard ratio, 0.62 [95% CI, 0.43 to 0.91]; P = .013; median, 13.4 v 9.2 months). Adverse events were consistent with the established safety profiles of olaparib and chemotherapy. CONCLUSION: Olaparib resulted in statistically significant and clinically relevant improvements in ORR and PFS compared with nonplatinum chemotherapy in patients with germline BRCA-mutated platinum-sensitive relapsed ovarian cancer who had received at least 2 prior lines of platinum-based chemotherapy.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Previously proposed criteria for preoperatively identifying endometrial cancer patients at low risk for lymph node metastasis remain to be verified. For this purpose, a prospective, multicenter observational study was performed. METHODS: Eligible patients with histologically confirmed endometrial cancer underwent magnetic resonance imaging (MRI) and serum cancer antigen 125 (CA 125) testing before surgery. The following criteria were used to identify low-risk patients: 1) endometrioid-type cancer, 2) no evidence of deep myometrial invasion on MRI, 3) no enlarged lymph nodes on MRI, 4) no suspicious metastasis out of the uterine corpus, and 5) serum CA 125 levels less than 35 U/mL. Systematic pelvic and/or para-aortic lymphadenectomy was performed for all patients. The primary endpoint was estimation of the negative predictive value (NPV). RESULTS: From January 2012 to December 2014, 529 patients from 20 hospitals in 3 Asian countries were consecutively enrolled. According to our criteria, 272 patients (51.4%) were categorized into the low-risk group. Fifty-three of the 529 patients (10.0%) had lymph node metastases; these patients included 8 (2.9%) falsely categorized as low-risk. The sensitivity and specificity of the criteria were 84.9% and 55.5%, respectively. The NPV of 97.1% was higher than the predefined target endpoint of 96%. CONCLUSIONS: The low-risk criteria based on preoperative tests were confirmed to be reliable and accurate for identifying patients at low risk for lymph node metastasis. These criteria may facilitate patient counseling and surgical decision making. Cancer 2017;123:263-272. © 2016 American Cancer Society.

RESUMEN

OBJECTIVE: To investigate whether the number of lymph nodes obtained during lymphadenectomy affects the survival of patients with intermediate- or high-risk endometrioid-type endometrial cancer. METHODS: A total of 476 patients who were diagnosed with FIGO stage IB to IIIC2 endometrioid adenocarcinoma through surgical staging, including hysterectomy and pelvic lymphadenectomy with or without paraaortic lymphadenectomy between 2000 and 2013 were retrospectively enrolled from four tertiary centers in Korea. Sentinel lymph node mapping was not performed in any patient. The number of nodes obtained and positive nodes, was extracted from pathologic report. RESULTS: Paraaortic lymphadenectomy was performed in 298 (62.6%) patients and 164 (34.4%) had stage IIIC disease. The isolated paraaortic lymph node metastasis rate decreased as the number of pelvic nodes obtained increased. In the total study population, an increase of negative pelvic and paraaortic nodes was associated with improved recurrence-free survival (RFS) and overall survival (OS) independent of other prognostic factors. In the node-positive group, an increase of negative pelvic nodes was an independent prognostic factor for RFS [hazard ratio (HR), 0.946; 95% confidence interval (CI), 0.906-0.988] and OS [HR, 0.907; 95% CI, 0.849-0.968]. In stage IIIC2 patients, 14 or less negative pelvic nodes was associated with poor RFS and OS. CONCLUSIONS: Removing as many pelvic nodes as possible is required to warrant accurate nodal staging and improve survival in patients with intermediate- or high-risk endometrial cancer. Sentinel lymph node mapping can be a resolution to minimize lymph node dissection without compromising staging accuracy.

RESUMEN

OBJECTIVE: Cervical cancer is responsible for more than a quarter of a million deaths globally each year, mostly in developing countries, making therapeutic advances in all health care settings a top priority. The Gynecologic Cancer InterGroup (GCIG) is a worldwide collaboration of leading national research groups that develops and promotes multinational trials in gynecologic cancer. In recognition of the pressing need for action, the GCIG convened an international meeting with expert representation from the GCIG groups and selected large sites in low- and middle-income countries. METHODS: The focus was to develop a consensus on several concepts for future clinical trials, which would be developed and promoted by the GCIG and launched with major international participation. The first half of the meeting was devoted to a resume of the current state of the knowledge and identifying the gaps in need of new evidence, validating control arms for present and future clinical trials and identifying national and international barriers for studies of cervix cancers. The second half of the meeting was concerned with achieving consensus on a path forward. RESULTS AND CONCLUSIONS: There were 5 principal outcomes as follows: first, a proposal to expand fertility-preserving options with neoadjuvant chemotherapy; second, validation of the assessment of sentinel lymph nodes using minimally invasive surgery with an emphasis on identification and management of low-volume metastasis, such as isolated tumor cells and micrometastasis; third, evaluation of hypofractionation for palliative and curative radiation under the umbrella of the GCIG Cervix Cancer Research Network; fourth, adding to the advances in antiangiogenesis therapy in the setting of metastatic disease; and fifth, developing a maintenance study among women at high risk of relapse. The latter 2 systemic interventions could study PI3K (phosphatidylinositol-3-kinase) inhibitors, immunotherapy, anti-human papillomavirus approaches, or novel antiangiogenic agents/combinations.

RESUMEN

Tolerogenic dendritic cells (tDCs) play an important role in inducing peripheral tolerance; however, few tDC-specific markers have been identified. The aims of this study were to examine whether tDCs show a different gene expression profile from that of immunogenic DCs and identify specific gene markers of each cell type, in DBA/1 mice. tDCs were generated by treating immature DCs (imDCs) with TNF-α and type II collagen. The gene expression profiles of mature (m)DCs and tDCs were then investigated by microarray analysis and candidate markers were validated by quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR). Supervised selection identified 75 gene signatures, 63 of which were consistently upregulated in mDCs and 12 of which were upregulated only in tDCs. Additionally, 10 genes were overexpressed or equally expressed in both tDCs and mDCs. Scin (tDC-specific genes) and Orm1, Pdlim4 and Enpp2 (mDC-specific genes) were validated by real-time qRT-PCR. Taken together, these results clearly show that tDCs and mDCs can be identified according to their expression of specific gene markers.

RESUMEN

PURPOSE: In contrast to high-dose therapeutic irradiation, definitive research detailing the physiological effects of low-dose irradiation is limited. Notably, the immunological response elicited after low-dose irradiation remains controversial. MATERIALS AND METHODS: Female C57BL/6 mice were whole- body-irradiated with a single or three daily fractions up to a total dose of 0.1, 1, or 10 cGy. Blood and spleen were harvested 2, 7 and 14 days after irradiation. RESULTS: The splenic CD4(+) T cell subpopulations were temporarily increased at 2 days after single or fractionated irradiation, whereas the percentage of dendritic cells (DC) and macrophages was decreased. Whereas CD8(+) T cell populations were decreased in single-dose irradiated mice at day 7, early and sustained reduction of CD8(+) T cell numbers was observed in fractionated- dose-irradiated mice from day 2 until day 14. In addition, single-dose irradiation resulted in a Th1 cytokine expression profile, whereas fractionated-dose irradiation drove a Th2 shift. Additionally, increased expression of immune-related factors was observed at early time-points with single-dose irradiation, in contrast to the dose-independent induction following fractionated-dose irradiation. CONCLUSIONS: Our results demonstrate that low-dose irradiation modulates the immune response in mice, where the sensitivity and kinetics of the induced response vary according to the dosing method.

RESUMEN

OBJECTIVES: We aimed to develop a risk model to predict a risk of suboptimal cytoreduction in primary surgery of ovarian cancer. METHODS: The clinical records and computed tomography (CT) data of 358 patients with stages II-IV epithelial ovarian cancer were reviewed. Tumor spread patterns identified by principal component analysis, CA-125, and a newly developed surgical skill index were integrated into a logistic model along with other variables. Internal validation was performed using bootstrapped re-sampling and calibration was assessed by goodness-of-fit test. RESULTS: Among the 358 patients, optimal cytoreduction, which was defined as no residual tumor, was achieved in 145 patients (40.5%). The surgical capacity of an individual institution was estimated by a surgical skill index, which was the frequency of complex surgeries in patients with advanced disease. In a multivariate model, two distinctive CT patterns of tumor spread (diffuse spread pattern and upper abdominal extension pattern), a surgical skill index, and serum CA-125 independently predicted a risk of suboptimal cytoreduction (P=0.006, P=0.013, P=0.031, and P=0.001, respectively). The model showed a C-statistic of .73 (95% confidence interval .67 to .79), which was significantly higher than tumor stage or ascites. Rigorous internal validation by bootstrapped re-sampling successfully confirmed the model. CONCLUSIONS: We identified two distinct tumor spread patterns of ovarian cancer, which can be integrated to improve a prediction model. Our model may be useful in patient referral or clinical trials for patient stratification.

RESUMEN

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.

RESUMEN

PURPOSE: Our study aimed to develop a model to predict distant recurrence in locally advanced cervical cancer, which can be used to select high-risk patients in enriched clinical trials. PATIENTS AND METHODS: Our study was a retrospective analysis of a multi-institutional cohort of patients treated between 2001 and 2009. According to the order of data submission, data from three institutions were allocated to a model development cohort (n = 434), and data from the remaining two institutions were allocated to an external validation cohort (n = 115). Patient information including [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) data and clinical outcome was modeled using competing risk regression analysis to predict 5-year cumulative incidence of distant recurrence. RESULTS: The competing risk analysis revealed that the following four parameters were significantly associated with distant recurrence: pelvic and para-aortic nodal positivity on FDG-PET, nonsquamous cell histology, and pretreatment serum squamous cell carcinoma antigen levels. This four-parameter model showed good discrimination and calibration, with a bootstrap-adjusted concordance index of 0.70. Also, the validation set showed good discrimination with a bootstrap-adjusted concordance index of 0.73. A user-friendly Web-based nomogram predicting 5-year probability of distant recurrence was developed. CONCLUSION: We have developed a robust model to predict the risk of distant recurrence in patients with locally advanced cervical cancer. Further, we discussed how the selective enrichment of the patient population could facilitate clinical trials of systemic chemotherapy in locally advanced cervical cancer.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.
