Incidence of inguinofemoral lymph node metastases at the first local recurrence of vulvar cancer: a Dutch nationwide study.

BACKGROUND: Up to 40% of vulvar cancer patients present with local recurrence within 10 years of follow-up. An inguinofemoral lymphadenectomy (IFL) is indicated if not performed at primary treatment. The incidence and risk factors for lymph node metastases (LNM) at first local recurrence, however, are unclear. Our aim was to determine the incidence of LNM at first local recurrence, in relation to previous groin treatment and clinicopathological factors. METHODS: A multicenter cohort study including vulvar cancer patients with a first macroinvasive local recurrence after primary surgical treatment between 2000 and 2015 was conducted in the Netherlands. Groin status at local recurrence was defined as positive (N+), negative (N-) or unknown (N?) and based on histology, imaging and follow-up. Patient-, tumour- and treatment characteristics of primary and recurrent disease were analysed. RESULTS: Overall, 16.3% (66/404) had a N+ groin status at first local recurrence, 66.4% (268/404) N- and 17.3% (70/404) N? groin status. The incidence of a N+ groin status was comparable after previous SLN and IFL, 11.5% and 13.8%, respectively. A N+ groin status was related to tumour size (25 vs.12 mm; P < 0.001), depth of invasion (5 vs. 3 mm; P < 0.001) and poorly differentiated tumours (22.9 vs. 11.9%; P = 0.050) at local recurrence. CONCLUSIONS: The incidence of LNM at first local recurrence in vulvar cancer patients was 16.3%, and independent of previous type of groin surgery. In accordance with primary diagnosis, tumour size, depth of invasion, and tumour grade were significantly associated with a positive groin status.

Treatment of bulky lymph nodes in locally advanced cervical cancer: boosting versus debulking.

OBJECTIVE: Treatment strategies for bulky lymph nodes in patients with locally advanced cervical cancer scheduled for definitive chemoradiation include nodal boosting with radiotherapy, surgical debulking, or both. The aim of this retrospective cohort study was to compare survival and toxicity in patients receiving these treatments and to compare them with a group that received neither form of treatment. METHODS: Women diagnosed between January 2009 and January 2017 with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB2, IIA2-IVA cervical cancer with lymph nodes ≥1.5 cm without upper limit on pretreatment imaging and treated with definitive chemoradiation were selected from the Netherlands Cancer Registry. Patients were categorized by intention-to-treat strategy: boosting, debulking, or neither treatment, with subgroup analysis for patients receiving both treatments, that is, debulking with boosting. Overall and relapse-free survival outcomes were compared by Kaplan-Meier and Cox regression analyses and toxicity by logistic regression analysis. RESULTS: Of 190 patients, 101 (53%) received only nodal boosting, 31 (16%) debulking alone, 29 (15%) debulking combined with boosting, and 29 (15%) received neither treatment. The 5 year overall and relapse-free survival for the treatment groups were 58%, 45% and 45% (p=0.19), and 47%, 44% and 46% (p=0.87), respectively. Multivariable Cox regression analyses demonstrated no differences in overall and relapse-free survival. Combination of debulking with boosting was associated with decreased overall and relapse-free survival compared with debulking alone (HR 2.47, 95% CI 1.22 to 5.00; and HR 2.37, 95% CI 1.14 to 4.93). Nodal boosting was independently associated with a decreased toxicity risk compared with debulking strategy (OR 0.37, 95% CI 0.16 to 0.83). CONCLUSIONS: This study showed no survival benefit from either nodal boosting or debulking strategy in patients with suspicious bulky nodes. Nodal boosting might, however, be associated with less toxicity. Dual treatment with debulking and boosting showed a worse survival outcome because this group probably represents patients with poor prognostic factors.

The prognostic value of the number of positive lymph nodes and the lymph node ratio in early-stage cervical cancer.

INTRODUCTION: To establish the impact of the number of lymph node metastases (nLNM) and the lymph node ratio (LNR) on survival in patients with early-stage cervical cancer after surgery. MATERIAL AND METHODS: In this nationwide historical cohort study, all women diagnosed between 1995 and 2020 with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA2-IIA1 cervical cancer and nodal metastases after radical hysterectomy and pelvic lymphadenectomy from the Netherlands Cancer Registry were selected. Optimal cut-offs for prognostic stratification by nLNM and LNR were calculated to categorize patients into low-risk or high-risk groups. Kaplan-Meier overall survival analysis and flexible parametric relative survival analysis were used to determine the impact of nLNM and LNR on survival. Missing data were imputed. RESULTS: The optimal cut-off point was ≥4 for nLNM and ≥0.177 for LNR. Of the 593 women included, 500 and 501 (both 84%) were categorized into the low-risk and 93 and 92 (both 16%) into the high-risk groups for nLNM and LNR, respectively. Both high-risk groups had a worse 5-year overall survival (p < 0.001) compared with the low-risk groups. Being classified into the high-risk groups is an independent risk factor for relative survival, with excess hazard ratios of 2.4 (95% confidence interval 1.6-3.5) for nLNM and 2.5 (95% confidence interval 1.7-3.8) for LNR. CONCLUSIONS: Presenting a patient's nodal status postoperatively by the number of positive nodes, or by the nodal ratio, can support further risk stratification regarding survival in the case of node-positive early-stage cervical cancer.

Hyperthermic Intraperitoneal Chemotherapy in Ovarian Cancer.

BACKGROUND: Treatment of newly diagnosed advanced-stage ovarian cancer typically involves cytoreductive surgery and systemic chemotherapy. We conducted a trial to investigate whether the addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery would improve outcomes among patients who were receiving neoadjuvant chemotherapy for stage III epithelial ovarian cancer. METHODS: In a multicenter, open-label, phase 3 trial, we randomly assigned 245 patients who had at least stable disease after three cycles of carboplatin (area under the curve of 5 to 6 mg per milliliter per minute) and paclitaxel (175 mg per square meter of body-surface area) to undergo interval cytoreductive surgery either with or without administration of HIPEC with cisplatin (100 mg per square meter). Randomization was performed at the time of surgery in cases in which surgery that would result in no visible disease (complete cytoreduction) or surgery after which one or more residual tumors measuring 10 mm or less in diameter remain (optimal cytoreduction) was deemed to be feasible. Three additional cycles of carboplatin and paclitaxel were administered postoperatively. The primary end point was recurrence-free survival. Overall survival and the side-effect profile were key secondary end points. RESULTS: In the intention-to-treat analysis, events of disease recurrence or death occurred in 110 of the 123 patients (89%) who underwent cytoreductive surgery without HIPEC (surgery group) and in 99 of the 122 patients (81%) who underwent cytoreductive surgery with HIPEC (surgery-plus-HIPEC group) (hazard ratio for disease recurrence or death, 0.66; 95% confidence interval [CI], 0.50 to 0.87; P=0.003). The median recurrence-free survival was 10.7 months in the surgery group and 14.2 months in the surgery-plus-HIPEC group. At a median follow-up of 4.7 years, 76 patients (62%) in the surgery group and 61 patients (50%) in the surgery-plus-HIPEC group had died (hazard ratio, 0.67; 95% CI, 0.48 to 0.94; P=0.02). The median overall survival was 33.9 months in the surgery group and 45.7 months in the surgery-plus-HIPEC group. The percentage of patients who had adverse events of grade 3 or 4 was similar in the two groups (25% in the surgery group and 27% in the surgery-plus-HIPEC group, P=0.76). CONCLUSIONS: Among patients with stage III epithelial ovarian cancer, the addition of HIPEC to interval cytoreductive surgery resulted in longer recurrence-free survival and overall survival than surgery alone and did not result in higher rates of side effects.

Radiotherapy is not indicated in patients with vulvar squamous cell carcinoma and only one occult intracapsular groin node metastasis.

OBJECTIVE: Most guidelines advise no adjuvant radiotherapy in vulvar squamous cell carcinoma and a single occult intracapsular lymph node metastasis. However, several recent studies have questioned the validity of this recommendation. The aim of this study was to analyze the groin recurrence rate in patients with a single intracapsular positive lymph node treated without adjuvant radiotherapy. METHODS: Patients with a single clinically occult intracapsular lymph node metastasis, treated without adjuvant radiotherapy, formed the basis for this study. Groin recurrences, and the risk of death, were analyzed in relation to the size of the metastasis in the lymph node and the lymph node ratio. Data were analyzed using SPSS, version 26.0 for Windows. RESULTS: After a median follow-up of 64 months, one of 96 patients (1%) was diagnosed with an isolated groin recurrence and another two (2.1%) were diagnosed with a combination of a local and a groin recurrence. The only isolated groin recurrence occurred in a contralateral lymph node negative groin. Size of the metastasis and lymph node ratio had no impact on the groin recurrence risk, nor on survival. The 5-year actuarial disease-specific and overall survivals were 79% and 62.5% respectively. The 5-year actuarial groin recurrence-free survival was 97%. CONCLUSION: Because of the low risk of groin recurrence and the excellent groin recurrence-free survival, we recommend that adjuvant radiotherapy to the groin in patients with vulvar squamous cell carcinoma and a single occult intracapsular lymph node metastasis can be safely omitted to prevent unnecessary toxicity and morbidity.

Phase II study of definitive chemoradiation for locally advanced squamous cell cancer of the vulva: An efficacy study.

OBJECTIVE: To evaluate feasibility of chemoradiation as alternative for extensive surgery in patients with locally advanced vulvar cancer and to report on locoregional control, toxicity and survival. METHODS: In a multicenter, prospective phase II trial patients with locally advanced vulvar cancer were treated with locoregional radiotherapy combined with sensitizing chemotherapy (capecitabine). Treatment feasibility, percentage locoregional control, survival and toxicity were evaluated. RESULTS: 52 patients with mainly T2/T3 disease were treated according to the study protocol in 10 centers in the Netherlands from 2007 to 2019. Full dose radiotherapy (tumor dose of 64.8Gy) was delivered in 92% and full dose capecitabine in 69% of patients. Most prevalent acute ≥ grade 3 toxicities were regarding skin/mucosa and pain (54% and 37%). Late ≥grade 3 toxicity was reported for skin/mucosa (10%), fibrosis (4%), GI incontinence (4%) and stress fracture or osteoradionecrosis (4%). Twelve weeks after treatment, local clinical complete response (cCR) and regional control (RC) rates were 62% and 75%, respectively. After 2 years, local cCR persisted in 22 patients (42%) and RC was 58%. Thirty patients (58%) had no evidence of disease at end of follow-up (median 35 months). In 9 patients (17%) extensive surgery with stoma formation was needed. Progression free survival was 58%, 51% and 45% and overall survival was 76%, 66%, 52% at 1,2, and 5 years. CONCLUSIONS: Definitive capecitabine-based chemoradiation as alternative for extensive surgery is feasible in locally advanced vulvar cancer and results in considerable locoregional control with acceptable survival rates with manageable acute and late toxicity.

The role of lymph nodes in cervical cancer: incidence and identification of lymph node metastases-a literature review.

Correct identification of patients with lymph node metastasis from cervical cancer prior to treatment is of great importance, because it allows more tailored therapy. Patients may be spared unnecessary surgery or extended field radiotherapy if the nodal status can be predicted correctly. This review captures the existing knowledge on the identification of lymph node metastases in cervical cancer. The risk of nodal metastases increases per 2009 FIGO stage, with incidences in the pelvic region ranging from 2% (stage IA2) to 14-36% (IB), 38-51% (IIA) and 47% (IIB); and in the para-aortic region ranging from 2 to 5% (stage IB), 10-20% (IIA), 9% (IIB), 13-30% (III) and 50% (IV). In addition, age, tumor size, lymph vascular space invasion, parametrial invasion, depth of stromal invasion, histological type, and histological grade are reported to be independent prognostic factors for the risk of nodal metastases. Furthermore, biomarkers can contribute to predict a patient's nodal status, of which the squamous cell carcinoma antigen (SCC-Ag) is currently the most widely used in squamous cell cervical cancer. Still, pre-treatment lymph node assessment is primarily performed by imaging, of which diffusion-weighted magnetic resonance imaging has the highest sensitivity and 2-deoxy-2-[18F]fluoro-D-glucose positron emission computed tomography the highest specificity. Imaging results can be combined with clinical parameters in nomograms to increase the accuracy of predicting positives nodes. Despite all the progress regarding pre-treatment prediction of lymph node metastases in cervical cancer in recent years, prediction rates are not robust enough to safely abandon surgical staging of the pelvic or para-aortic region yet.

Central radiology assessment of the randomized phase III open-label OVHIPEC-1 trial in ovarian cancer.

INTRODUCTION: Hyperthermic intraperitoneal chemotherapy (HIPEC) improved investigator-assessed recurrence-free survival and overall survival in patients with stage III ovarian cancer in the phase III OVHIPEC-1 trial. We analyzed whether an open-label design affected the results of the trial by central blinded assessment of recurrence-free survival, and tested whether HIPEC specifically targets the peritoneal surface by analyzing the site of disease recurrence. METHODS: OVHIPEC-1 was an open-label, multicenter, phase III trial that randomized 245 patients after three cycles of neoadjuvant chemotherapy to interval cytoreduction with or without HIPEC using cisplatin (100 mg/m2). Patients received three additional cycles of chemotherapy after surgery. Computed tomography (CT) scans and serum cancer antigen 125 (CA125) measurements were performed during chemotherapy, and during follow-up. Two expert radiologists reviewed all available CT scans. They were blinded for treatment allocation and clinical outcome. Central revision included Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 measurements and peritoneal cancer index scorings at baseline, during treatment, and during follow-up. Time to centrally-revised recurrence was compared between study arms using Cox proportional hazard models. Subdistribution models compared time to peritoneal recurrence between arms, accounting for competing risks. RESULTS: CT scans for central revision were available for 231 patients (94%) during neoadjuvant treatment and 212 patients (87%) during follow-up. Centrally-assessed median recurrence-free survival was 9.9 months in the surgery group and 13.2 months in the surgery+HIPEC group (HR for disease recurrence or death 0.72, 95% CI 0.55 to 0.94; p=0.015). The improved recurrence-free survival and overall survival associated with HIPEC were irrespective of response to neoadjuvant chemotherapy and baseline peritoneal cancer index. Cumulative incidence of peritoneal recurrence was lower after surgery+HIPEC, but there was no difference in extraperitoneal recurrences. CONCLUSION: Centrally-assessed recurrence-free survival analysis confirms the benefit of adding HIPEC to interval cytoreductive surgery in patients with stage III ovarian cancer, with fewer peritoneal recurrences. These results rule out radiological bias caused by the open-label nature of the study.

Analysis of isolated loco-regional recurrence rate in intermediate risk early cervical cancer after a type C2 radical hysterectomy without adjuvant radiotherapy.

BACKGROUND: The efficacy of adjuvant radiotherapy in patients with intermediate risk early cervical cancer after radical hysterectomy is still under debate. Most guidelines recommend adjuvant radiotherapy, whereas others consider observation a viable option. OBJECTIVE: To investigate if patients with intermediate risk factors for cervical cancer who underwent radical hysterectomy may benefit from adjuvant radiotherapy. METHODS: Consecutive patients with tumor confined to the cervix and intermediate risk factors (according to Sedlis), treated between January 1982 and December 2014 who were observed after a type C2 radical hysterectomy formed the basis for this study. The frequency of recurrences, specifically isolated loco-regional recurrences, and the risk of death from recurrences, were analyzed. Data were analyzed using SPSS, version 23.0 for Windows RESULTS: A total of 161 patients were included in the analysis. Median age was 40 (range 20-76). Stages IB1 and IB2 were seen in 87 (54%) and 74 patients (46%), respectively. Squamous cell and non-squamous histology was seen in 114 (70.8%) and 47 patients (29.2%), respectively. Of the 161 patients, 25 (15.5%) had recurrent disease, of whom nine had an isolated loco-regional recurrence (5.6%). Median time to recurrence for isolated loco-regional recurrences was 28 months (range 9-151). Treatment for an isolated loco-regional recurrence was radiotherapy (n = 4) and chemoradiotherapy (n = 5). Four patients (2.5%) died from disease as a result of an isolated loco-regional recurrence. Actuarial disease- specific survival was 93.0% for the total group. No variables were found that predicted an isolated loco-regional recurrence. DISCUSSION: The mortality from isolated loco-regional recurrence in patients with intermediate risk factors for cervical cancer who underwent only radical hysterectomy type C2 was 2.5%. Further studies should compare outcomes between patients who undergo a type C2 radical hysterectomy without adjuvant radiotherapy with those undergoing a less radical hysterectomy but with adjuvant radiotherapy.

Surgical Treatment of Early-Stage Cervical Cancer: A Multi-Institution Experience in 2124 Cases in The Netherlands Over a 30-Year Period.

OBJECTIVE: This study aimed to describe the pattern of recurrence and survival related to prognostic variables, including type of surgery as a clinical variable, in patients surgically treated for early cervix cancer. METHODS: Records of 2124 patients who underwent a radical hysterectomy for International Federation of Gynaecology and Obstetrics stage I/IIA cervical cancer between 1982 and 2011 were reviewed. Clinical-pathologic prognostic variables, also including extent of parametrectomy, were identified and used in a multivariable Cox proportional hazard model to explore associations between disease-free survival (DFS) and prognostic variables. RESULTS: The 5-year DFS for the total group was 86%. Large tumor diameter, nonsquamous histology, lymph node metastases, parametrial involvement, lymph vascular space invasion, deep stromal invasion, and less radical surgery were independent poor prognostic variables for survival. Disease-free survival was independently associated with the type of radical hysterectomy with pelvic lymphadenectomy in favor of more radical parametrectomy (hazard ratio, 2.0; 95% confidence interval, 1.6-2.5). This difference was not found in tumors with a diameter of at least 20 mm. CONCLUSIONS: This study confirms that variables such as large tumor diameter, nonsquamous histology, lymph vascular space invasion, deep stromal invasion, positive lymph nodes, and parametrial infiltration are poor prognostic variables in early cervix cancer treated by surgery. The extent of parametrectomy had no influence on survival in tumors of 20 mm or less. For larger tumors, a more radical hysterectomy might be associated with better DFS. Taking into account the possible bias in this study as a result of its retrospective design, ideally a prospective cohort study with clear definition of radicality is necessary to answer this important clinical question.

Completing or Abandoning Radical Hysterectomy in Early-Stage Lymph Node-Positive Cervical Cancer: Impact on Disease-Free Survival and Treatment-Related Toxicity.

INTRODUCTION: Management regarding completing hysterectomy in case of intraoperative finding of positive lymph nodes in early-stage cervical cancer differs between institutions. The aim of this study was to compare survival and toxicity after completed hysterectomy followed by adjuvant (chemo-)radiotherapy versus abandoned hysterectomy and primary treatment with chemoradiotherapy (CRT). METHODS: A retrospective multicenter cohort study was performed. All patients were scheduled for radical hysterectomy with pelvic lymphadenectomy (RHL). In the RHL group, hysterectomy was completed followed by adjuvant (chemo-)radiotherapy. In the second group, hysterectomy was abandoned, and CRT was conducted. Primary outcomes were disease-free survival (DFS) and overall survival. A multivariable analysis on DFS was performed. Toxicity was scored according to the National Cancer Institute CTCAE (Common Terminology Criteria for Adverse Events) v4.03. RESULTS: A total of 121 patients were included (RHL, n = 89; CRT, n = 32). There was no difference in overall survival (84% vs 77%). Five-year DFS was in favor of completing RHL (81% vs 67%). Multivariable analysis showed that, corrected for lymph node variables, treatment regimen was not associated with DFS. After RHL, pelvic recurrence rate was significantly lower compared with CRT (2% vs 16%). CTCAE grade 3-4 toxicity rates were higher in the CRT compared with the RHL group (59% vs 30%), mainly because of differences in chemotherapy-related hematologic toxicity. CONCLUSIONS: In patients with clinically N0 early-stage cervical cancer with intraoperative detection of positive nodes, completing RHL followed by adjuvant (chemo-)radiotherapy may result in a better pelvic control compared with abandoning hysterectomy and treatment with chemoradiotherapy. However, if corrected for lymph node variables, treatment (RHL or CRT) was not associated with DFS.

European Society of Gynaecological Oncology Guidelines for the Management of Patients With Vulvar Cancer.

OBJECTIVE: The aim of this study was to develop clinically relevant and evidence-based guidelines as part of European Society of Gynaecological Oncology's mission to improve the quality of care for women with gynecologic cancers across Europe. METHODS: The European Society of Gynaecological Oncology Council nominated an international development group made of practicing clinicians who provide care to patients with vulvar cancer and have demonstrated leadership and interest in the management of patients with vulvar cancer (18 experts across Europe). To ensure that the statements are evidence based, the current literature identified from a systematic search has been reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group (expert agreement). The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 181 international reviewers including patient representatives independent from the development group. RESULTS: The guidelines cover diagnosis and referral, preoperative investigations, surgical management (local treatment, groin treatment including sentinel lymph node procedure, reconstructive surgery), radiation therapy, chemoradiation, systemic treatment, treatment of recurrent disease (vulvar recurrence, groin recurrence, distant metastases), and follow-up.

Prognostic effect of different PD-L1 expression patterns in squamous cell carcinoma and adenocarcinoma of the cervix.

Programmed death-ligand 1 (PD-L1) is expressed in various immune cells and tumor cells, and is able to bind to PD-1 on T lymphocytes, thereby inhibiting their function. At present, the PD-1/PD-L1 axis is a major immunotherapeutic target for checkpoint inhibition in various cancer types, but information on the clinical significance of PD-L1 expression in cervical cancer is largely lacking. Here, we studied PD-L1 expression in paraffin-embedded samples from two cohorts of patients with cervical cancer: primary tumor samples from cohort I (squamous cell carcinoma, n=156 and adenocarcinoma, n=49) and primary and paired metastatic tumor samples from cohort II (squamous cell carcinoma, n=96 and adenocarcinoma, n=31). Squamous cell carcinomas were more frequently positive for PD-L1 and also contained more PD-L1-positive tumor-associated macrophages as compared with adenocarcinomas (both P<0.001). PD-L1-positive tumor-associated macrophages were found to express CD163 and/or CD14 by triple fluorescent immunohistochemistry, demonstrating an M2-like phenotype. Interestingly, disease-free survival (P=0.022) and disease-specific survival (P=0.046) were significantly poorer in squamous cell carcinoma patients with diffuse PD-L1 expression as compared with patients with marginal PD-L1 expression (i.e., on the interface between tumor and stroma) in primary tumors. Disease-specific survival was significantly worse in adenocarcinoma patients with PD-L1-positive tumor-associated macrophages compared with adenocarcinoma patients without PD-L1-positive tumor-associated macrophages (P=0.014). No differences in PD-L1 expression between primary tumors and paired metastatic lymph nodes were detected. However, PD-L1-positive immune cells were found in greater abundance around the metastatic tumors as compared with the paired primary tumors (P=0.001 for squamous cell carcinoma and P=0.041 for adenocarcinoma). These findings point to a key role of PD-L1 in immune escape of cervical cancer, and provide a rationale for therapeutic targeting of the PD-1/PD-L1 pathway.

Repeat sentinel lymph node procedure in patients with recurrent vulvar squamous cell carcinoma is feasible.

OBJECTIVE: Standard treatment of primary T1 squamous cell carcinoma (SCC) of the vulva <4cm consists of wide local excision (WLE) and sentinel lymph node (SLN) procedure of the groin(s). In case of a local recurrence WLE and inguino femoral lymphadenectomy (IFL) is generally recommended. In this study we assessed the feasibility of repeat SLN procedure in patients with recurrent vulvar SCC who were not able or willing to undergo IFL. METHODS: A retrospective study was performed in consecutive patients with recurrent vulvar SCC who underwent a repeat SLN procedure between 2006 and 2014. We present the clinical and pathological outcomes. The study conforms to the STROBE guidelines. RESULTS: A total number of 27 patients aged 35-87years at first diagnosis of SCC of the vulva were identified. Median follow-up after 2nd surgery was 27.4 (range 2-96) months. In 78% of patients and in 84% of the groins the repeat SLN procedure was successful. No structured questionnaires were used to describe details on the repeat SLN procedures but in general the gynecologic oncologists experienced repeat SLN procedures more challenging compared to primary procedures. There were no groin recurrences documented. CONCLUSIONS: Our findings suggest that it is feasible to perform a repeat SLN procedure in recurrent vulvar SCC, but the procedure appears technically more challenging compared to primary setting, resulting in a lower SLN identification rate.

Long-term Pelvic Floor Function and Quality of Life After Radical Surgery for Cervical Cancer: A Multicenter Comparison Between Different Techniques for Radical Hysterectomy With Pelvic Lymphadenectomy.

OBJECTIVE: This study aimed to compare urinary and bowel symptoms and quality of life (QoL) among women treated with a Wertheim-Meigs (WM, type III) or Wertheim-Okabayashi (WO, type IV) radical hysterectomy with pelvic lymphadenectomy for early-stage cervical cancer. METHODS: In this cross-sectional observational study, patients treated with a WO or a (nerve sparing) WM radical hysterectomy (with or without adjuvant radiotherapy) between January 2000 and December 2010 in the Center for Gynaecological Oncology Amsterdam or Leiden University Medical Center were included. To assess QoL, urinary and bowel symptoms we used the EORTC QLQ-C30, EORTC QLQ-CX24, and Leiden Questionnaire. We performed a multivariate analysis to identify factors associated with urinary symptoms. RESULTS: Two hundred sixty-eight women were included (152 WO and 116 WM). Quality of life was not significantly different in patients treated by WO or WM. Urinary symptoms were more often reported by patients in the WO group compared to the WM group: "feeling of urine retention" (53% vs 32%), "feeling less/no urge to void" (59% vs 14%), and "timed voiding" (49% vs 10%). With regard to bowel symptoms, there was no difference between both. Multivariate analysis showed that surgical technique was an independent factor for differences in urinary symptoms. CONCLUSIONS: Patients undergoing more radical surgery for early-stage cervical cancer report significantly more urinary dysfunction, whereas bowel function and health-related QoL are not decreased.

Results of radical surgery in women with stage IB2/IIA2 cervical cancer.

INTRODUCTION: There is ongoing discussion about the primary treatment of women with bulky early-stage cervical cancer. Because of the high number of patients who need adjuvant (chemo)radiotherapy after initial surgical treatment, some state that primary (chemo)radiotherapy should be the treatment of choice to prevent morbidity. The aim of our study is to assess the results of radical surgery for women with bulky early-stage cervical cancer in terms of recurrence patterns and survival. MATERIALS AND METHODS: We conducted a retrospective cohort study. We included 129 women who underwent a radical hysterectomy with pelvic lymphadenectomy for stage IB2/IIA2 cervical cancer between 1984 and June 2010. Disease-specific survival was measured using a Kaplan-Meier method and univariate and multivariate regression analyses were performed to determine prognostic factors associated with survival. A literature search was performed to analyze our data in the context of findings from the literature. RESULTS: Five-year disease-specific survival was 84%. Fifty percent of the women received adjuvant treatment. The pelvic recurrence rate was 8%. With our multivariate analysis we found that histology, tumor diameter, and parametrial involvement were independently associated with disease-specific survival. Our literature search showed wide diversity in rates of adjuvant treatment after initial surgery as well as for survival and recurrence rates. CONCLUSIONS: In the context of current knowledge about survival and side effects of various treatments for bulky early-stage cervical cancer, radical surgery is a good treatment option in these patients. Depending on the type of surgery used, adjuvant radiotherapy can be minimized.

Evaluation of response to hormone therapy in patients with measurable adult granulosa cell tumors of the ovary.

INTRODUCTION: The aim of this study was to retrospectively determine the objective response rate to hormone therapy (HT) for patients with a measurable adult granulosa cell tumor (GCT) of the ovary in a consecutive series of patients. MATERIAL AND METHODS: All patients with an adult GCT who were treated with HT [steroidal progestins, selective estrogen receptor modulators, aromatase inhibitors and gonadotropin-releasing hormone agonists] within three referral hospitals were identified and their records were screened for HT administration. The main outcome measure was the objective response rate to HT. RESULTS: We identified 127 patients with an adult GCT, of whom 81 (64%) had a recurrence. Twenty-five of these patients (20%) were treated with hormones, of whom 22 had measurable disease at the start of their treatment, i.e. a tumor of more than 1 cm in diameter as seen on imaging, either as a recurrence or as residual disease. The pooled objective response rate, defined as the proportion of patients whose best overall response to hormone therapy was either complete response or partial response to HT, was 18% (4/22) (95% confidence interval 6-41%). In one patient (4.5%) a complete response and in three (14%) a partial response was described. Fourteen patients (64%) had stable disease and in four patients (18%) disease was progressive. CONCLUSIONS: Although several case reports described good responses to HT in patients with a GCT, we found a response in only four of 22 patients in this relatively large consecutive series of patients.

Hormone therapy in ovarian granulosa cell tumors: a systematic review.

OBJECTIVE: This systematic review assessed the effectiveness of hormone therapy (HT) in patients with a granulosa cell tumor (GCT) of the ovary. METHODS: Medline (OVID), EMBASE (OVID), the Cochrane Central Register of Controlled Trials (CENTRAL), prospective trial registers and PubMed (as supplied by publisher-subset) were searched up to January 13, 2014. No restrictions were applied. Two reviewers independently screened studies for eligibility and extracted data using a standardized, piloted extraction form. Studies evaluating the response to hormone therapy in patients with a GCT were included. The primary outcome was the objective response rate (ORR) to hormone therapy. RESULTS: In total, nineteen studies including 31 patients were eligible. Pooled ORR to hormone therapy was 71.0% (95% Confidence Interval 52-85). In 25.8% a complete response and in 45.2% a partial response was described. Four patients had stable disease. In five patients disease was progressive. Various hormone treatments showed different results, for instance aromatase inhibitors (AI) demonstrated response in nine out of nine therapies (100%) and tamoxifen in none out of three (0%). Median progression free survival (PFS) after the start of hormone therapy was 18 months (range 0-60). CONCLUSIONS: Despite the limited available data, hormone therapy appears to be a good treatment alternative for patients with advanced-stage or recurrent GCT. However, study quality is poor and prospective studies are needed to confirm clinical benefit of hormone therapy in GCTs.
