Carboplatin-paclitaxel compared to Carboplatin-Paclitaxel-Bevacizumab in advanced or recurrent endometrial cancer: MITO END-2 - A randomized phase II trial

OBJECTIVE

Increased Vascular Endothelial Growth Factor Receptor (VEGF) expression in endometrial cancer (EC) is associated with a poor prognosis. Preliminary clinical data reported Bevacizumab effectiveness in EC both as single agent and in combination with chemotherapy.

METHODS

In a phase II trial, patients with advanced (FIGO stage III-IV) or recurrent EC were randomized to receive Carboplatin-Paclitaxel standard dose for 6-8 cycles vs Carboplatin-Paclitaxel and Bevacizumab 15 mg/kg in combination with chemotherapy and maintenance until disease progression or unacceptable toxicity. The primary endpoint was progression free survival (PFS).

RESULTS

108 patients were randomized; PFS (10.5 vs 13.7 months, HR 0.84 p = 0.43), overall response rate (ORR 53.1% vs 74.4%) and overall survival (OS) (29.7 vs 40.0 months, HR 0.71 p = 0.24) resulted in a non-significant increase in Bevacizumab treated patients. The PFS increase became significant when an exploratory analysis with the Breslow test was used. Moreover, patients treated with Bevacizumab experienced a significant increase in 6-month disease control rate (70.4% vs 90.7%). Cardiovascular events were more frequent in the experimental arm ("de novo" grade ≥2 hypertension 21% vs 0% and grade ≥2 thromboembolic events 11% vs 2% in the Bevacizumab vs standard treatment arm, respectively).

CONCLUSIONS

Bevacizumab combined with chemotherapy in the treatment of advanced/recurrent EC failed to demonstrate a significant increase in PFS in the MITO END-2 trial. Nevertheless, these preliminary data suggests some effectiveness of the antiangiogenic agent which merits further exploration in a larger population with a better molecular characterization.

RECIST 1.1 criteria predict recurrence-free survival in advanced ovarian cancer submitted to neoadjuvant chemotherapy

OBJECTIVE

Neoadjuvant chemotherapy plus interval debulking surgery is growing treatment strategy for advanced ovarian cancer patients with unresectable disease. Here, we aimed to assess predictors of surgical unresectability and survival of patients submitted to neoadjuvant chemotherapy plus interval debulking surgery.

METHODS

Data of consecutive 193 patients undergoing neoadjuvant chemotherapy plus interval debulking surgery were retrospectively evaluated in four Italian oncologic centers. RECIST 1.1 guidelines were used to assess response to neoadjuvant chemotherapy. Survival outcomes were evaluated using Kaplan-Meier and Cox proportional hazard models.

RESULTS

Overall, 155 (80.3%) and 38 (19.7%) patients had optimal and non-optimal cytoreduction at the time of interval debulking surgery. Via multivariate analysis, age (OR: 2.87 (95%CI: 1.29, 6.36) per 10-year increase) and radiological response to neoadjuvant chemotherapy (OR: 48.1 (95%CI: 6.33, 365.3)) impact on the inability to perform a complete cytoreduction. Patients having complete or partial response experienced a significant better disease-free survival than patients having stable or progressive disease at radiological examination (median disease-free survival 16.8 vs. 11.0 months; HR: 0.42 (95%CI: 0.09, 0.78); p = .001). Radiological response did not predict for overall survival (p = .719).

CONCLUSIONS

RECIST1.1 response criteria might be helpful to predict surgical resectability and disease-free survival of advanced stage ovarian cancer patients undergoing neoadjuvant chemotherapy plus interval debulking surgery.

Treatment of recurrent ovarian cancer with pegylated liposomal doxorubicin: a reappraisal and critical analysis

The vast majority of ovarian cancer relapses on front-line therapy and the optimal treatment of recurrent ovarian cancer remains controversial. This review is based on the relevant published literature indexed in PubMed on pegylated liposomal doxorubicin (PLD), either alone or in combination with other drugs, as one option in relapsed disease. PLD showed an improved pharmacokinetic profile, with a slower plasma clearance and a longer circulation time, compared to other conventional doxorubicin formulations. PLD is considered to have little potential for cardiotoxicity, even at prolonged and high cumulative doses, although there appears to be room for improvement in terms of maximal dose allowed. Notwithstanding, there remain some concerns about cardiac safety, and patient monitoring is generally advocated. No data are available on the possibility to rechallenge PLD treatment in recurrent ovarian cancer, as already known for other drugs. Optimization of treatment regimens with PLD will allow a more rational treatment in advanced ovarian cancers for which few therapeutic options are available.

Pegylated liposomal doxorubicin re-challenge in patients with ovarian cancer relapse: a multicenter retrospective study

Background

Pegylated liposomal doxorubicin (PLD) is an active and well-tolerable treatment in ovarian cancer relapse, either alone or in combination with other drugs. No data are available on the possibility to rechallenge PLD treatment in long survivor patients with recurrent ovarian cancer, as evaluated for platinum agent, paclitaxel and gemcitabine. The aim of the present study was to evaluate the anti-tumor activity and the toxicity profile of re-challenge of PLD in recurrent ovarian cancer patients.

Methods

Data on 27 patients with epithelial ovarian cancer treated in the last ten years (2007-2017) with palliative PLD rechallenge were included in this multicenter retrospective Italian study.

Results

The objective response rate to PLD re-treatment were complete response in 19%, partial response in 30% and stable disease in 37%. Only 1 case of G4 hematological toxicity was reported. No patient experienced severe cardiac impairment (G2-4).

Conclusion

PLD rechallenge represents an active and safe possibility of treatment for long survivor ovarian cancer patients.

Capecitabine in patients with platinum-pretreated advanced or recurrent cervical carcinoma: a retrospective study

Background

Cervical cancer is a common malignancy among women and, when recurring, presents a dismal prognosis. After platinum failure, second-line treatments report response rates ranging from 3–15%, a median progression-free survival of about 3 months and a median overall survival of about 5.5 months.

To retrospectively evaluate the activity and safety of capecitabine in patients with advanced/recurrent cervical carcinoma.

Methods

A retrospective review of medical records of recurrent cervical cancer patients, who had failed a previous platinum–paclitaxel treatment and received oral capecitabine 1250 mg/m2 twice daily continuously from day 1 to day 14 every 21 days, was performed from December 2013 to March 2018 at the Gynecologic Oncology Unit of the Fondazione IRCCS National Cancer Institute of Milan, Italy. The response rate was evaluated every three cycles according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 criteria. Common Terminology Criteria for Adverse Events version 4.0 were used to evaluate adverse events.

Results

We retrospectively analyzed 35 patients with recurrent cervical carcinoma, treated with oral capecitabine. All patients had previously received and failed a combination of carboplatin plus paclitaxel as first-line therapy for advanced/recurrent disease. Median age at the first capecitabine administration was 53 years (range 27–82). All patients were evaluable for response: the overall response rate was 34.2% (2.8% complete responses and 31.4% partial responses) with a clinical benefit rate of 57% (overall response rate plus 22.8% stabilizations of disease). The most common grade 1–2 adverse events per patient were fatigue (71.3%), hand-foot syndrome (57.0%), diarrhea (31.3%), constipation (17.0%), and nausea (10.4%). Only three patients (8.5%) reported grade 3 adverse events.

Conclusions

Our data suggest that oral capecitabine should be considered an active and safe treatment in patients with recurrent cervical carcinoma after platinum failure. Based on these results, we consider capecitabine as warranting further clinical evaluation.

Treatment of the Mayer-Rokitansky-Küster-Hauser syndrome with autologous in vitro cultured vaginal tissue: descriptive study of long-term results and patient outcomes

OBJECTIVE

Evaluating sexual function and quality of life (QoL) in patients treated with a modified Abbé-McIndoe technique using in vitro cultured autologous vaginal mucosa.

DESIGN

Descriptive study.

SETTING

Policlinico Umberto I, Sapienza University of Rome.

POPULATION

From 2006 to 2016, 39 women affected by Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) underwent vaginoplasty at our centre using a modified Abbé-McIndoe technique with in vitro cultured autologous vaginal tissue.

METHODS

For each patient, vaginal tissue was obtained by full-thickness biopsy of the vaginal vestibule. Following enzymatic dissociation, cells were cultured for 2-3 weeks before the transplant.

MAIN OUTCOME MEASURES

Each patient completed two validated questionnaires to quantify sexual function and QoL: the Female Sexual Function Index (FSFI), administered at 12, 36, and 60 months, and the Psychological General Well Being Index (PGWBI) administered at 0, 6, and 36 months after surgery.

RESULTS

Twelve months after surgery, 29 patients were engaging in regular sexual activity. The FSFI test results showed a satisfactory sexual function compared to the general population, with median values of 25.85 (range 4.6-30.5) at 12 months, 27.2 (range 4.4-33.6) at 36 months, and 29.6 (range 23.9-33.6) at 60 months. The PGWBI questionnaire showed a median score of 420.5 (range 108-540) before surgery, and 459 (range 252-533) at the 60-month follow-up.

CONCLUSIONS

Vaginoplasty performed with the use of autologous vaginal tissue, besides ensuring a long-term satisfying sex life, helps in achieving an improvement in QoL that is maintained over time.

TWEETABLE ABSTRACT

Vaginoplasty using in vitro vaginal tissue ensures a satisfactory sexual function and improves quality of life.

[Il ruolo di niraparib nel trattamento del carcinoma ovarico: attualità e prospettive.]

Riassunto. I PARP inibitori interferiscono con la riparazione del danno nella singola elica del DNA determinando una progressione del difetto nella doppia elica. In circa il 50% delle pazienti con carcinoma dell'ovaio sieroso di alto grado sono presenti difetti nei meccanismi di ricombinazione omologa, deputati alla riparazione del danno della doppia elica del DNA. L'incapacità di riparare il danno si traduce nella morte cellulare, un processo definito "letalità sintetica". Nella famiglia dei PARP inibitori il niraparib è stato il primo a essere approvato dalla FDA nel trattamento delle pazienti con carcinoma ovarico ricorrente indipendentemente dalla presenza o assenza di mutazioni BRCA. Questo risultato è stato raggiunto grazie ai dati emersi dal trial di fase III ENGOT-OV16/NOVA, favorevoli in termini di prolungamento della sopravvivenza libera da progressione e associati a un buon profilo di tossicità. Ulteriori trial clinici sono in corso per valutare ulteriori indicazioni all'impiego di niraparib nel trattamento del carcinoma ovarico.

Locally Advanced Cervical Cancer: Is a Trimodality Treatment a Safe and Effective Approach?

BACKGROUND

Chemoradiotherapy (CRT) is the standard of care for locally advanced cervical cancer (LACC). Pre-treatment lymph nodes (LN) assessment may have an important therapeutic role. CRT followed by adjuvant chemotherapy increased progression free survival (PFS) and overall survival (OS). Our study evaluated the feasibility and the effectiveness of a trimodality strategy in patients with LACC and positive LN.

METHODS

Consecutive patients with LACC treated at the National Cancer Institute of Milan were enrolled. All patients underwent pelvic and para-aortic extraperitoneal laparoscopic lymphadenectomy to assess the nodal status. After surgery, patients received radiotherapy followed by chemotherapy according to the stage of disease.

RESULTS

Between April 2012 and October 2013, 19 cervical cancer patients were enrolled. Overall, 10 (52.6%) patients presented with positive LN: 6 in the pelvic area and 4 both in the pelvic and para-aortic area. No perioperative major complications occurred. The most common surgical-related adverse events were bleeding (26%), respiratory distress (5%), infection (5%) and the development of lymphoceles (25%). Overall, 15 (78.9%) complete responses and 2 (10.5%) partial responses were registered. After a median follow-up of 43.3 months, 89.5% of patients were alive at the last visit, and 3-year PFS was 63%.

CONCLUSIONS

Trimodality treatment appears feasible, well tolerated and promising in terms of oncologic outcome.

Spotlight on olaparib in the treatment of BRCA-mutated ovarian cancer: design, development and place in therapy

Epithelial ovarian cancer is the sixth most common cancer among women worldwide and the first cause of death among gynecological malignancies. Most of the patients present recurrent disease and unfortunately cannot be cured. The unsatisfactory results obtained with salvage chemotherapy have elicited investigators to search for novel biological agents capable of achieving a better control of the disease. In the setting of homologous recombination deficiency, the DNA errors that occur cannot be accurately repaired, and the treatment with poly(ADP-ribose) polymerase (PARP) inhibition results in definitive cell death in a process called synthetic lethality. As a result of two positive clinical trials, Olaparib was approved in 2014 by U.S. Food and Drug Administration and European Medicines Agency as the first-in-class PARP inhibitor. Olaparib is effective and well tolerated in homologous recombination deficient patients. Several studies with Olaparib have been conducted in the recurrent setting either as maintenance in platinum-responsive patients or as a single agent. Ongoing trials are focused on the use of olaparib as maintenance in the first-line ovarian cancer setting alone or in combination with antiangiogenic agents. Future perspectives will probably investigate the association of olaparib with novel agents as check-point inhibitors and PI3K-AKT inhibitors. The PARP inhibitor era is just at the beginning.

LASER treatment for women with high-grade vaginal intraepithelial neoplasia: A propensity-matched analysis on the efficacy of ablative versus excisional procedures

OBJECTIVE

To investigate the long-term effectiveness of LASER treatment in women affected by high-grade vaginal intra-epithelial neoplasia.

METHODS

Data of consecutive women treated for high-grade vaginal intra-epithelial neoplasia were retrieved. Efficacy and long-term effectiveness of ablative and excisional procedures were tested using a propensity-matched algorithm. Risk of recurrence over the time was assessed using Kaplan-Meier and Cox models.

RESULTS

Overall, 204 patients met the inclusion criteria. LASER ablation and exicision were performed in 169 (82.8%) and 35 (17.2%) patients. A total of 41 (20%) patients developed high-grade vaginal intraepithelial neoplasia at a median follow-up of 65 (range, 6-120) months. We observed that only HPV persistence (HR: 2.37 [95%CI:1.03, 5.42]; P = 0.04) was associated with the risk of recurrence at multivariate analysis. Seven (3.4%) invasive cancers of the lower genital tract were observed in our population. Considering the efficacy of type of procedure (after we applied the propensity-matched analysis), we observed that type of procedure did not influence persistence of HPV infection (22.8% after excision and 15.7% after ablation; P = 0.424). Similarly, recurrence (17.1% vs. 18.6%; P = 1.00) and lower genital tract (2.8% vs. 1.4%; P = 1.00) rates were similar between groups.

CONCLUSIONS

Women affected by high-grade vaginal intra-epithelial neoplasia are at high risk of recurrence. LASER ablation seems to be equivalent to excision in term of long-term effectiveness. Lasers Surg. Med. 50:933-939, 2018. © 2018 Wiley Periodicals, Inc.

Rucaparib: a new treatment option for ovarian cancer

INTRODUCTION

Approximately 50% of high-grade serous ovarian cancers present a deficiency in the pathways involved in homologous recombination (HR). PARP inhibitors prevent single-strand DNA damage repair and determine a progression of the defect towards double-strand breaks, which results in a process known as 'synthetic lethality'. Areas covered: In this review, the authors discuss the efficacy and toxicity of rucaparib either as a single agent or as a maintenance treatment for ovarian cancer. This includes the NGS Foundation Medicine evaluation of the role of this drug in the treatment algorithm of ovarian cancer. Moreover, perspectives on the future development of this drug are presented. Expert opinion: The FDA has approved this drug for the treatment of recurrent BRCA-mutated ovarian cancers, which were previously treated with at least two chemotherapies and has accepted the supplemental new drug application for maintenance use in patients who respond to platinum-based chemotherapy via the Prescription Drug User Fee Act (PDUFA) on 6 April 2018. European Medicines Agency (EMA) approval in the same setting is awaited. The possibility of using PARP inhibitors as a maintenance therapy, as a front-line therapy to combat recurrence, and in combination with anti-angiogenic agents and immune-therapies appears to be of particular interest.

A score system for complete cytoreduction in selected recurrent ovarian cancer patients undergoing secondary cytoreductive surgery: predictors- and nomogram-based analyses

OBJECTIVE

To test the applicability of the Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) and Memorial Sloan Kettering (MSK) criteria in predicting complete cytoreduction (CC) in patients undergoing secondary cytoreductive surgery (SCS) for recurrent ovarian cancer (ROC).

METHODS

Data of consecutive patients undergoing SCS were reviewed. The Arbeitsgemeinschaft Gynäkologische Onkologie OVARian cancer study group (AGO-OVAR) and MSK criteria were retrospectively applied. Nomograms, based on AGO criteria, MSK criteria and both AGO and MSK criteria were built in order to assess the probability to achieve CC at SCS.

RESULTS

Overall, 194 patients met the inclusion criteria. CC was achieved in 161 (82.9%) patients. According to the AGO-OVAR criteria, we observed that CC was achieved in 87.0% of patients with positive AGO score. However, 45 out of 71 (63.4%) patients who did not fulfilled the AGO score had CC. Similarly, CC was achieved in 87.1%, 61.9% and 66.7% of patients for whom SCS was recommended, had to be considered and was not recommended, respectively. In order to evaluate the predictive value of the AGO-OVAR and MSK criteria we built 2 separate nomograms (c-index: 0.5900 and 0.5989, respectively) to test the probability to achieve CC at SCS. Additionally, we built a nomogram using both the aforementioned criteria (c-index: 0.5857).

CONCLUSION

The AGO and MSK criteria help identifying patients deserving SCS. However, these criteria might be strict, thus prohibiting a beneficial treatment in patients who do not met these criteria. Further studies are needed to clarify factors predicting CC at SCS.

Predicting Factors for High-Grade Cervical Dysplasia in Women With Low-Grade Cervical Cytology and Nonvisible Squamocolumnar Junction

OBJECTIVE

To assess the risk of developing high-grade cervical dysplasia among women with low-grade cervical cytology and nonvisible squamocolumnar junction (SCJ) at colposcopic examination.

METHODS

Data of consecutive women with low-grade intraepithelial lesion(≤LSIL) undergoing colposcopic examination, which was unsatisfactory (due to the lack of the visualization of the entire SCJ), were retrospectively reviewed. The risk of developing high-grade cervical intraepithelial neoplasia (CIN2+) was assessed using Kaplan-Meier and Cox models.

RESULTS

Data of 86 women were retrieved. Mean (standard deviation [SD]) age was 36.3 (13.4) years. A total of 71 (82.5%) patients had high-risk human papillomavirus (HR-HPV) at the time of diagnosis. Among the 63 patients undergoing repetition of HPV testing, 15 (24%) and 48 (76%) women had positive and negative tests for HR-HPV at 12 months, respectively. We observed that 5 (33%) of 15 patients with HPV persistence developed CIN2+, while only 1 (2%) patient of 48 patients without HPV persistence developed CIN2+ (odds ratio [OR]: 23.5; 95% confidence interval [CI]: 2.46-223.7; P < .001). The length of HR-HPV persistence correlated with an increased risk of developing CIN2+ ( P < .001; P for trend). High-risk HPV persistence is the only factor predicting for CIN2+ (hazard ratio: 3.19; 95% CI: 1.55-6.57; P = .002).

CONCLUSIONS

High-risk HPV persistence predicts the risk of developing CIN2+ in patients with unsatisfactory colposcopic examination. Further studies are warranted in order to implement the use of HPV testing in patients with unsatisfactory colposcopy.

The role of human papillomavirus vaccines in cervical cancer: Prevention and treatment

Human papillomavirus (HPV) is the most common sexually transmitted disease, worldwide. Primary prevention thorough vaccination si able to reduce the burden of HPV-related lesions. Ten years ago the Food and drug Administration (FDA) approved the first vaccine against HPV. In the last decades, growing data on safety and effectiveness have been collected. In the present review we report the current knowledge on vaccine against HPV, highlighting the current value and prospective regarding the widespread diffusion of HPV vaccines. The role of emerging therapeutic vaccines is reviewed.

Nerve-Sparing Approach Improves Outcomes of Patients Undergoing Minimally Invasive Radical Hysterectomy: A Systematic Review and Meta-Analysis

Few studies have investigated the efficacy and safety of the nerve-sparing approach via minimally invasive surgery for the treatment of cervical cancer. We aimed to review the current evidence comparing nerve-sparing minimally invasive radical hysterectomy (NS-MRH) with conventional minimally invasive radical hysterectomy (MRH). This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD#57655). Overall, 675 patients were included: 350 (51.9%) and 325 (48.1%) patients undergoing MRH and NS-MRH, respectively. MRH was associated with a shorter operative time in comparison with NS-MRH (mean difference = 32.57 minutes; 95% CI, 22.87-42.48). The estimated blood loss (mean difference = 97.14 mL, 20.01-214.29) and transfusion rate (odds ratio [OR] = 0.67; 95% confidence interval [CI], 0.15-3.01) did not differ statistically between the 2 groups. The risk of developing intraoperative (OR = 0.43; 95% CI, 0.08-2.23) and severe postoperative (OR = 0.63; 95% CI, 0.17-2.39) complications was similar between NS-MRH and MRH. Patients undergoing NS-MRH experienced lower voiding (OR = 0.39; 95% CI, 0.19-0.81) dysfunction rates than patients undergoing MRH. Moreover, a trend toward lower sexual (OR = 0.25; 95% CI, 0.06-1.07) and rectal (OR = 0.12; 95% CI, 0.01-1.02) issues was observed for patients having NS-MRH compared with patients undergoing MRH. Survival outcomes are not influenced by the type of surgical approach (recurrence [OR = 1.27; 95% CI, 0.49-3.28] and death [OR = 1.01; 95% CI, 0.36-2.83]) rates. The pooled data suggested that NS-MRH is equivalent to MRH for the treatment of cervical cancer and may be superior in reducing pelvic floor dysfunction rates. However, because of the low level of evidence of the included studies, further randomized trials are warranted.

Chemotherapy-related leukopenia as a biomarker predicting survival outcomes in locally advanced cervical cancer

OBJECTIVE

To investigate the impact of hematologic toxicity and leukopenia in locally advanced cervical cancer patients undergoing neoadjuvant chemotherapy (NACT).

STUDY DESIGN

Data of consecutive patients undergoing platinum-based NACT followed by surgery were retrospectively searched in order to evaluate the impact of chemotherapy-related toxicity on survival outcomes. Toxicity was graded per the Common Terminology Criteria for Adverse Events (CTCAEv.4.03). Survival outcomes were evaluated using Kaplan-Meir and Cox hazard models.

RESULTS

Overall, 126 patients were included. Among those, 94 (74.6%) patients experienced grade2+ hematologic toxicity; while, grade2+ non-hematologic toxicity occurred in 11 (8.7%) patients. After a median follow-up of 37.1 (inter-quartile range, 12-57.5) months, 21 (16.6%) patients experienced recurrence. Via multivariate analysis, no factor was independently associated with disease-free survival; while a trend toward worse prognosis was observed for patients experiencing grade2+ leukopenia at cycle-3 (HR:3.13 (95%CI: 0.94, 10.3); p=0.06). Similarly, grade2+ leukopenia (HR:9.98 (95%CI: 1.14, 86.6); p=0.03), lymph-node positivity (HR:14.6 (95%CI:1.0, 214.4); p=0.05) and vaginal involvement (HR:5.81 (95%CI:1.43, 23.6); p=0.01) impacted on overall survival, at multivariate analysis. Magnitude of leukopenia correlated with survival (p<0.001).

CONCLUSIONS

Although, our data have to be confirmed by prospective investigations, the present study shows an association between the occurrence of leukopenia and survival outcomes. NACT-related immunosuppression might reduce the response against the tumor, thus promoting cancer progression.

Efficacy of adjuvant chemotherapy in early stage uterine leiomyosarcoma: A systematic review and meta-analysis

OBJECTIVE

We sought to review the current evidence in order to test the efficacy of adjuvant chemotherapy in improving disease-free survival in patients affected by early stage uterine leiomyosarcoma.

METHODS

On July 2016, literature was searched in order to identify trials comparing different postoperative adjuvant strategies for patients diagnosed with early stage uterine leiomyosarcoma.

RESULTS

Our analysis included 360 patients: 145 (40%), 53 (15%), and 155 (43%) had chemotherapy (with or without radiotherapy), radiotherapy, and observation, respectively. Seven (2%) patients who had radiotherapy with or without chemotherapy were excluded from further analysis in order to reduce risk of biases. Administration of chemotherapy (with or without radiotherapy) did not improve outcomes in comparison to observation (OR: 0.79 (95%CI: 0.48, 1.29)), or radiotherapy (OR: 0.90 (95%CI: 0.42, 1.94)). Loco-regional recurrence rate was similar comparing patients undergoing chemotherapy (with or without radiotherapy) with having observation alone (OR: 0.84 (95%CI: 0.44, 1.60)). Similarly, pooled results suggested that chemotherapy administration did not affect distant recurrence rate in comparison to no chemotherapy (OR: 0.80 (95%CI: 0.50, 1.28)), and observation alone (OR: 0.99 (95%CI: 0.60, 1.64)). However, patients undergoing chemotherapy (with or without radiotherapy) experienced a trend towards lower risk of developing distant recurrences (OR: 0.49 (95%CI: 0.24, 1.03)) and a higher risk of developing loco-regional recurrences (OR: 3.45 (95%CI: 1.02, 11.73)) than patients undergoing radiotherapy.

CONCLUSIONS

In early stage uterine leiomyosarcoma, the role of adjuvant chemotherapy remains unclear. Owing to the high recurrence rate, even in the early stage of disease, further innovative therapeutic strategies have to be tested.

Morcellator's Port-site Metastasis of a Uterine Smooth Muscle Tumor of Uncertain Malignant Potential After Minimally Invasive Myomectomy

Since the safety warning from the US Food and Drug Administration on the use of power morcellators, minimally invasive procedures involving the removal of uterine myomas and large uteri are under scrutiny. Growing evidence suggests that morcellation of undiagnosed uterine malignancies is associated with worse survival outcomes of patients affected by uterine sarcoma. However, to date, only limited data regarding morcellation of low-grade uterine neoplasms are available. In the present article, we reported a case of a (morcellator) port-site implantation of a smooth muscle tumor that occurred 6 years after laparoscopic morcellation of a uterine smooth muscle tumor of uncertain potential. This case highlights the effects of intra-abdominal morcellation, even in low-grade uterine neoplasms. Caution should be used when determining techniques for tissue extraction; the potential adverse consequences of morcellation should be more fully explored.

Extraperitoneal Robotic-Assisted Para-Aortic Lymphadenectomy in Gynecologic Cancer Staging: Current Evidence

We reviewed the current evidence on the safety, effectiveness, and applicability of extraperitoneal robotic-assisted para-aortic lymphadenectomy (ExtRA-PAL) as the staging procedure of gynecologic malignancies. PubMed (MEDLINE), Scopus, Web of Science databases, and ClinicalTrials.gov were searched for original studies reporting outcomes of ExtRA-PAL. Quality of the included studies and their level of recommendation were assessed using the Grading of Recommendations, Assessment, Development, and Evaluation and the American College of Obstetricians and Gynecologists guidelines, respectively. Overall, 62 studies were identified; after a process of evidence acquisition 5 original investigations were available for this review that included 98 patients undergoing ExtRA-PAL. The main surgical indication was staging for cervical cancer (n = 71, 72%). The mean (SD) number of para-aortic node yielded was 15.4 (±4.7) nodes. Blood transfusion and intraoperative complication rates were 2% and 6%, respectively. ExtRA-PAL was completed in 88 patients (90%). Six (6%) and 4 (4%) patients had conversion to other minimally invasive procedures and open surgery, respectively. Success rate was 99% among patients undergoing ExtRA-PAL without concomitant procedures. Overall, mean (SD) length of hospital stay was 2.8 (±0.5) days. Twenty-four patients (24%) developed postoperative events. According to the Clavien-Dindo grading system, grades IIIa and IIIb morbidity rates were 12% and 2%, respectively. No grades IV and V morbidity occurred. ExtRA-PAL is associated with a high success rate and a relative low morbidity rate. However, because of the limited data on this issue, further studies are warranted to assess the long-term effectiveness of this procedure.

Impact of p16(INK4a) immunohistochemistry staining on interobserver agreement on the diagnosis of cervical intraepithelial neoplasia

OBJECTIVES

This study aimed to compare the interobserver Cohen κ on H&E staining and on H&E plus p16(INK4a) staining of all cervical biopsy specimens in a population-based screening program.

METHODS

All the colposcopy-guided biopsies generated by the routine screening of 23,258 women aged 25 to 64 years were stained with H&E and H&E plus p16. Biopsy specimens were reviewed by six external experts.

RESULTS

The four diagnoses were available in 441 cases. The interobserver κ values were 0.52 (95% confidence interval [CI], 0.45-0.58) and 0.48 (95% CI, 0.42-0.56) with H&E and H&E + p16, respectively, when using a five-group classification (normal, CIN 1, CIN 2, CIN 3, and cancer); adopting a two-group classification (≤CIN 1 and ≥CIN 2), the values were 0.75 (95% CI, 0.66-0.82) and 0.70 (95% CI, 0.61-0.79), respectively.

CONCLUSIONS

The use of p16 on all cervical biopsy specimens in a screening program showed virtually no effect on reproducibility of the histologic diagnosis.

Prognostic value of p16-INK4A protein in women with negative or CIN1 histology result: a follow-up study

P16-INK4A overexpression has been proposed as a prognostic marker to manage the follow up of women with positive cytology and/or HPV test but without high-grade cervical intraepithelial neoplasia (CIN2+). This study measures the relative risk (RR) of CIN2+ of p16 positive versus negative in these women. All the women referred to colposcopy from October 2008 to September 2010 with negative or CIN1 colposcopy-guided biopsy were included in the study; women surgically treated or having a CIN2-3 were excluded. All baseline biopsies were dyed with hematoxylin and eosin and p16. Women were followed up according to screening protocols, with cytology or colposcopy at 6 or 12 months. CIN2/3 RRs and 95% confidence intervals (95%CI) were computed. Of 442 eligible women, 369 (83.5%) had at least one follow-up episode. At baseline, 113 (30.6%) were CIN1, 248 (67.2%) negative, and 8 (2.2%) inadequate histology; 293 (79.4%) were p16-negative, 64 (17.3%) p16 positive and 12 (3.2%) not valid. During follow up, we found ten CIN2 and three CIN3; of these, six were p16 positive (sensitivity 46%, 95% CI 19-75). The absolute risk among p16 positives was 9.4/100 compared to 1.7/100 of the p16 negatives (RR 5.5; 95% CI 1.7-17.4). The risk was also higher for CIN1 than for histologically negative women (RR 4.4; 95% CI 1.3-14.3). The RR for p16 in CIN1 did not change (RR 5.2; 95% CI 0.6-47.5). P16 overexpression is a good candidate for modulating follow-up intensity after a negative colposcopy but is limited by its low prospective sensitivity.
