Objective: To assess the role of histopathological and molecular features in predicting the risk of nodal metastases in apparent early-stage endometrial cancer patients undergoing sentinel node mapping., Methods: This is a prospective trial. Consecutive patients with apparent early-stage endometrial cancer, undergoing laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and sentinel node mapping, were enrolled. Histological and molecular features were used to predict the node positivity., Results: Charts of 223 apparent early-stage endometrial cancer patients were included in this study. Four (1.8%) patients were excluded from this study due to the lack of data about molecular features. Additionally, nine (4%) patients did not meet the inclusion criteria (due to the presence of peritoneal carcinomatosis or bulky nodes (the presence of p53 abnormality correlated with the presence of advanced stage disease (p<0.001)). The study population included 178 (84.8%) and 32 (15.2%) patients with endometrioid and non-endometrioid endometrial cancer, respectively. According to pathological uterine risk factors, 93 (44.3%), 45 (21.4%), 40 (19.1%), and 32 (15.2%) were classified as low, intermediate, intermediate-high, and high-risk, respectively. Using the surrogate molecular classification, 10 (4.8%), 42 (20%), 57 (27.1%), and 101 (48.1%) were included in the POLE mutated, p53 abnormal, MMRd/MSI-H, and NSMP, respectively. Overall, 41 (19.5%) patients were detected with positive nodes. Molecular features were not associated with the risk of having nodal metastases (OR 1.03, 95% CI 0.21 to 5.05, p=0.969 for POLE mutated; OR 0.788, 95% CI 0.32 to 1.98, p=0.602 for p53 abnormal; OR 1.14, 95% CI 0.53 to 2.42, p=0.733 for MMRd/MSI-H). At multivariable analysis, only deep myometrial invasion (OR 3.318, 95% CI 1.357 to 8.150, p=0.009) and lymphovascular space invasion (OR 6.584, 95% CI 2.663 to 16.279, p<0.001) correlated with the increased risk of positive nodes., Conclusion: Our data suggest that molecular classification does not seem useful to tailor the need of nodal dissection in apparent early-stage endometrial cancer. p53 abnormality predicts the risk of having advanced disease at presentation. Further external validation is needed., Clinical Trial Registration: NCT05793333., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2024. No commercial re-use.

Objective: To compare survival outcomes and patterns of recurrence between endometriosis-associated ovarian cancer patients and non-endometriosis-associated ovarian cancer patients., Methods: This retrospective study included data of consecutive patients with endometrioid or clear cell ovarian cancer treated at the Fondazione IRCCS Istituto Nazionale dei Tumori di Milano between January 2010 and June 2021. Patients were assigned to one of two groups according to the absence or presence of endometriosis together with ovarian cancer at final histological examination. Survival outcomes were assessed using Kaplan-Meier and Cox hazard models. Proportions in recurrence rate and pattern of recurrence were evaluated using the Fisher exact test., Results: Overall, 83 women were included in the endometriosis-associated ovarian cancer group and 144 in the non-endometriosis-associated ovarian cancer group, respectively. Patients included in the non- endometriosis-associated ovarian cancer group had a shorter disease-free survival than those in the endometriosis-associated ovarian cancer group (23.4 (range 2.0-168.9) vs 60.9 (range 4.0-287.8) months; p<0.001). Univariable and multivariable analyses showed that the association with endometriosis, previous hormonal treatment, early stage at presentation, and endometrioid histology were related to better disease-free survival in the entire study population. Similarly, patients in the non-endometriosis-associated ovarian cancer group had a shorter median (range) overall survival than those in the endometriosis-associated ovarian cancer group (54.4 (range 0.7-190.6) vs 77.6 (range 4.5-317.8) months; p<0.001). Univariable and multivariable analyses showed that younger age at diagnosis, association with endometriosis, and early stage at presentation were related to better overall survival. The recurrence rate was higher in the non-endometriosis-associated ovarian cancer group (63/144 women, 43.8%) than in the endometriosis-associated ovarian cancer group (17/83 women, 20.5%; p<0.001)., Conclusions: Endometriosis-associated ovarian cancer patients had significantly longer disease-free survival and overall survival than non-endometriosis-associated ovarian cancer patients, while the recurrence rate was higher in non-endometriosis-associated ovarian cancer patients., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2024.

Background: In addition to the diagnostic accuracy of imaging methods, patient-reported satisfaction with imaging methods is important., Objective: To report a secondary outcome of the prospective international multicenter Imaging Study in Advanced ovArian Cancer (ISAAC Study), detailing patients' experience with abdomino-pelvic ultrasound, whole-body contrast-enhanced computed tomography (CT), and whole-body diffusion-weighted magnetic resonance imaging (WB-DWI/MRI) for pre-operative ovarian cancer work-up., Methods: In total, 144 patients with suspected ovarian cancer at four institutions in two countries (Italy, Czech Republic) underwent ultrasound, CT, and WB-DWI/MRI for pre-operative work-up between January 2020 and November 2022. After having undergone all three examinations, the patients filled in a questionnaire evaluating their overall experience and experience in five domains: preparation before the examination, duration of examination, noise during the procedure, radiation load of CT, and surrounding space. Pain perception, examination-related patient-perceived unexpected, unpleasant, or dangerous events ('adverse events'), and preferred method were also noted., Results: Ultrasound was the preferred method by 49% (70/144) of responders, followed by CT (38%, 55/144), and WB-DWI/MRI (13%, 19/144) (p<0.001). The poorest experience in all domains was reported for WB-DWI/MRI, which was also associated with the largest number of patients who reported adverse events (eg, dyspnea). Patients reported higher levels of pain during the ultrasound examination than during CT and WB-DWI/MRI (p<0.001): 78% (112/144) reported no pain or mild pain, 19% (27/144) moderate pain, and 3% (5/144) reported severe pain (pain score >7 of 10) during the ultrasound examination. We did not identify any factors related to patients' preferred method., Conclusion: Ultrasound was the imaging method preferred by most patients despite being associated with more pain during the examination in comparison with CT and WB-DWI/MRI., Trial Registration Number: NCT03808792., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2024.

Gestational choriocarcinoma accounts for 5% of gestational trophoblastic neoplasms. Approximately 50%, 25%, and 25% of gestational choriocarcinoma occur after molar pregnancies, term pregnancies, and other gestational events, respectively. The FIGO scoring system categorizes patients into low (score 0 to 6) and high risk (score 7 or more) choriocarcinoma. Single-agent and multi-agent chemotherapy are used in low- and high-risk patients, respectively. Chemotherapy for localized disease has a goal of eradication of disease without surgery and is associated with favorable prognosis and fertility preservation. Most patients with gestational choriocarcinoma are cured with chemotherapy; however, some (<5.0%) will die as a result of multi-drug resistance, underscoring the need for novel approaches in this group of patients. Although there are limited data due to its rarity, the treatment response with immunotherapy is high, ranging between 50-70%. Novel combinations of immune checkpoint inhibitors with targeted therapies (including VEGFR-2 inhibitors) are under evaluation. PD-L1 inhibitors are considered a potential important opportunity for chemo-resistant patients, and to replace or de-escalate chemotherapy to avoid or minimize chemotherapy toxicity. In this review, the Rare Tumor Working Group and the European Organization for Research and Treatment of Cancer evaluated the current landscape and further perspective in the management of patients diagnosed with gestational choriocarcinoma., Competing Interests: Competing interests: Competing interests not related to the topic of this investigation: GB: Novartis AG Pharma (C/A, H), Italian Ministry of Health (RG); NC: AstraZeneca (C/A, SH), Seattle Genetics (C/A, SH), MSD (SAB), Mersana (C/A, SH), eTheRNA immunotherapies NV (C/A, SH), Roche (travel expenses), Genmab (travel expenses), Amgen (travel expenses).

Introduction: To evaluate oncological and obstetrical outcomes of early stage cervical cancer patients who underwent conservative management to retain childbearing potential., Methods: Data of women (aged <40 years) who underwent fertility sparing treatment for International Federation of Gynecology and Obstetrics (FIGO) stage IA1 with lymphovascular invasion (LVSI) and IB1 cervical cancer were prospectively collected. All patients underwent cervical conization/s and laparoscopic nodal evaluation (pelvic lymphadenectomy/sentinel node mapping). Oncological and obstetrical outcomes were assessed., Results: Overall, 39 patients met inclusion criteria; 36 (92.3%) women were nulliparous. There were: 3 (7.7%) IA1-LVSI+; 11 (28.2%) IA2; and 25 (64.1%) IB1 cervical cancers, according to 2018 FIGO stage classification. Histological types were 22 (56.4%) squamous carcinoma and 17 (43.6%) adenocarcinoma. Pelvic lymphadenectomy was performed in 29 (74.4%) patients, while 10 (25.6%) patients had only sentinel node mapping. In 4 (10.3%) patients conservative treatment was discontinued due to nodal involvement and 2 (5.1%) patients requested definitive treatment (hysterectomy) after a negative lymph node evaluation. Among 33 (84.6%) patients who retained their childbearing potential, 17 (51.5%) had a second conization. 2 (6.1%) patients relapsed and underwent definitive treatment. After a median follow-up of 51 months (range 1-184) no deaths were reported. 22 (70.9%) patients attempted to conceive. There were 13 natural pregnancies among 12 (54.5%) women who got pregnant. Live birth rate was 76.9%: 9 (69.2%) term and 1 (7.7%) preterm (at 32 weeks) deliveries. 2 (15.4%) miscarriages (first and second trimester) and 1 (7.7%) termination of pregnancy for medical reasons were recorded., Conclusion: Conization plus laparoscopic nodal evaluation may be a safe and feasible conservative option in the setting of fertility-sparing treatment for early-stage cervical cancer patients., Competing Interests: Competing interests: ES has received honoraria from Theramex, Merck-Serono and HRA.

Objective: To report on the performance of hysteroscopic injection of tracers (indocyanine green (ICG) and technetium-99m (Tc-99m)) for sentinel lymph node (SLN) mapping in endometrial cancer., Methods: Single-center retrospective evaluation of consecutive patients who underwent SLN mapping following hysteroscopic peritumoral injection of tracer. Detection rate (overall/bilateral/aortic) diagnostic accuracy, and oncologic outcomes were evaluated., Results: A total of 221 procedures met the inclusion criteria. Mean patient age was 60 (range 28-84) years and mean body mass index was 26.9 (range 15-47) kg/m 2 . In 164 cases (70.9%) mapping was performed laparoscopically. The overall detection rate of the technique was 94.1% (208/221 patients). Bilateral pelvic mapping was found in 62.5% of cases with at least one SLN detected and was more frequent using ICG than with Tc-99m (73.8% vs 53.3%; p<0.001). In 47.6% of cases SLNs mapped in both pelvic and aortic nodes, and in five cases (2.4%) only in the aortic area. In eight patients (3.8%) SLNs were found in aberrant (parametrial/presacral) areas. Mean number of detected SLNs was 3.7 (range 1-8). In 51.9% of cases at least one node other than SLNs was removed. Twenty-six patients (12.5%) had nodal involvement: 12 (46.2%) macrometastases, six (23.1%) micrometastases, and eight (30.7%) isolated tumor cells. In 12 cases (46.8%) the aortic area was involved. Overall, 6/221 (2.7%) patients had isolated para-aortic nodes. Three false-negative results were found, all in the Tc-99m group. All had isolated aortic metastases. Overall sensitivity was 88.5% (95% CI 71.7 to 100.0) and overall negative predictive value was 96.5% (95% CI 86.8 to 100.0). There were 10 (4.8%) recurrences: five abdominal/distant, four vaginal, and one nodal (in the aortic area following a unilateral mapping plus side-specific pelvic lymphadenectomy). Most recurrences (9/10 cases) were patients in whom a completion lymphadenectomy was performed. No deaths were reported after a mean follow-up of 47.7 months., Conclusions: Hysteroscopic injection of tracers for SLN mapping in endometrial cancer is as accurate as cervical injection with a higher detection rate in the aortic area. ICG improves the bilateral detection rate. Adding lymphadenectomy to SLN mapping does not reduce the risk of relapse., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2020.

Objective: Women with Lynch syndrome have a risk up to 40-60% of developing endometrial cancer, which is higher than their risk of developing colorectal or ovarian cancer. To date, no data on the outcomes of patients with Lynch syndrome diagnosed with non-endometrioid endometrial cancer are available. The goal of this study was to evaluate the outcome of patients with Lynch syndrome diagnosed with non-endometrioid endometrial cancer., Methods: Data from consecutive patients diagnosed with Lynch syndrome and with a histological diagnosis of non-endometrioid endometrial cancer were retrospectively collected in two referral institutes in Italy. A case-control comparison (applying a propensity matching algorithm) was performed in order to compare patients with proven Lynch syndrome and controls. Inclusion criteria were: (a) histologically-proven endometrial cancer; (b) detection of a germline pathogenic variant in one of the MMR genes; (c) adequate follow-up. Only carriers of pathogenic or likely pathogenic variants (ie, class 5 and 4 according to the InSiGHT classification) were included in the study. Survival outcomes were assessed using KaplanMeier and Cox models., Results: Overall, 137 patients with Lynch syndrome were collected. Mean patient age was 49.2 (10.9) years. Genes involved in the Lynch syndrome included MLH1 , MSH2 , and MSH6 in 43%, 39%, and 18% of cases, respectively. The study population included 27 patients with non-endometrioid endometrial cancer, who were matched 1:2 with patients with sporadic cancers using a propensity matching algorithm. After a median follow-up of 134 months (range 1-295), 2 (7.4%) of the 27 patients developed recurrent disease (3 and 36 months) and subsequently died of disease (7 and 91 months). Patients diagnosed with Lynch syndrome experienced better disease-free survival (HR 7.86 (95% CI 1.79 to 34.5); p=0.006) and overall survival (HR 5.33 (95% CI 1.18 to 23.9); p=0.029) than controls., Conclusions: Non-endometrioid endometrial cancer occurring in patients with Lynch syndrome might be associated with improved oncologic outcomes compared with controls. Genetic/molecular profiling should be investigated in order to better understand the mechanism underlying the prognosis., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2020.

Objective: Nodal involvement is one of the most important prognostic factors in cervical cancer patients. We aimed to assess the prognostic role in relation to the burden of nodal disease in stage IIICp cervical cancer., Methods: Data on all consecutive patients diagnosed with cervical cancer undergoing primary surgery (radical hysterectomy plus lymphadenectomy) or neoadjuvant chemotherapy followed by radical hysterectomy plus lymphadenectomy, between January 1980 and December 2017, were collected in a dedicated database. Exclusion criteria were: (1) consent withdrawal; (2) synchronous malignancies (within 5 years). Survival outcomes were assessed using Kaplan-Meier and Cox models., Results: Overall, 177 (14.1%) of 1257 patients with cervical cancer were diagnosed with positive lymph nodes. After a median follow-up of 58 (range 4-175) months, 66 (37.3%) and 37 (20.9%) patients developed recurrent disease and died of disease, respectively. Via multivariate analysis, positive para-aortic nodes (HR 2.62, 95% CI 1.12 to 6.11; p=0.025) and the number of positive nodes (HR 1.06, 95% CI 1.02 to 1.11; p=0.002) correlated with worse disease-free survival. Furthermore, the number of positive nodes (HR 1.06, 95% CI 1.01 to 1.12; p=0.021) correlated with worse overall survival. Number of positive nodes (1, 2 or ≥3) strongly correlated with both disease-free survival (p<0.001, log-rank test) and overall survival (p=0.001, log-rank test). Focusing on patients receiving adjuvant radiation and chemotherapy, the number of positive lymph nodes was associated with response to treatment (p<0.001). Median disease-free survival was 100, 42, and 12 months for patients with one, two, or three or more positive lymph node(s), respectively (p<0.001, log-rank test)., Conclusions: In stage IIICp cervical cancer, adjuvant radiation and chemotherapy provides adequate overall survival in patients diagnosed with only one metastatic node, while survival outcomes are poor in patients with two or more metastatic nodes. This highlights the need for innovative treatments in patients with a high burden of lymphatic disease., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2019.

Objectives: To assess the survival of patients who have received an operation for recurrent cervical and endometrial cancer and to determine prognostic variables for improved oncologic outcome., Methods: A retrospective multicenter analysis of the medical records of 518 patients with cervical (N = 288) or endometrial cancer (N = 230) who underwent surgery for disease recurrence and who had completed at least 1 year of follow-up., Results: The median survival reached 57 months for patients with cervical cancer and 113 months for patients with endometrial cancer after surgical treatment of recurrence (p = 0.036). Histological sub-type had a significant impact on overall survival, with the best outcome in endometrial endometrioid cancer (121 months), followed by cervical squamous cell carcinoma, cervical adenocarcinoma, or other types of endometrial cancer (81 vs 35 vs 35 months; p <0.001). The site of recurrence did not significantly influence survival in cervical or in endometrial cancer. Cancer stage at first diagnosis, tumor grade, lymph node status at recurrence, progression-free interval after first diagnosis, and free resection margins were associated with improved overall survival on univariate analysis. On multivariate analysis, the stage at first diagnosis and resection margins were significant independent predictive parameters of an improved oncologic outcome., Conclusion: Long-term survival can be achieved via secondary cytoreductive surgery in selected patients with recurrent cervical and endometrial cancer. An excellent outcome is possible even if the recurrence site is located in the lymph nodes. The possibility of achieving complete resection should be the main criterion for patient selection., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2019.

Objective: Lynch syndrome is a risk factor for developing endometrial carcinoma. Our aim was to evaluate the impact of gene-specific germline pathogenic variants on clinical features of patients affected by endometrial cancer., Methods: Patients with a diagnosis of endometrial cancer and with a germline pathogenic variant in mismatch repair genes were reviewed. Patients were classified on the basis of classes of risk according to the ESGO-ESGO-ESTRO (European Society of Medical Oncology/European Society of Gynaecological Oncology/European Society for Radiotherapy and Oncology) guidelines. One-way analysis of variance (ANOVA) and Kruskal-Wallis test were performed to compare three groups of continuous parametric and non-parametric variables, respectively. χ 2 test was used to analyze proportions., Results: Overall, 68 patients with endometrial cancer and Lynch syndrome were evaluated. Ten (14.7%) patients were excluded because of absence of information about the gene involved in Lynch syndrome, thus leaving 58 (85.3%) patients available for the final analysis. MLH1 , MSH2, and MSH6 pathogenic variants were observed in 19 (32.7%), 33 (56.9%), and six (10.3%) patients, respectively. Mean±SD age at endometrial cancer diagnosis was 51±6.4, 43.5±7.4, and 60.3±8.8 years (p=0.0002). Prevalence of non-endometrioid endometrial cancer was 15.7%, 24.2%, and 0% in the MLH1 , MSH2, and MSH6 groups, respectively (p=0.345). According to the ESMO-ESGO-ESTRO classification, low, intermediate, and high risk endometrial cancer accounted for 47.3%, 10.5%, and 42.1% of the MLH1 group, 57.6%, 3%, and 39.4% of the MSH2 group, and 50%, 50%m and 0% of the MSH6 group (p=0.009)., Conclusions: Patients with MLH1 and MSH2 pathogenic variants are at a higher risk of early onset of endometrial cancer than patients with MSH6 pathogenic variants., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2019.

Objective: The aim of the study was to evaluate outcomes of patients with unresectable advanced ovarian cancer experiencing complete response (CR) to neoadjuvant chemotherapy., Methods: Data of consecutive patients undergoing neoadjuvant chemotherapy plus interval debulking surgery (IDS) were retrospectively reviewed in 4 Italian centers. Using a propensity-matching algorithm, we compared data of patients achieving CR with neoadjuvant chemotherapy (no macroscopic either microscopic residual disease (RD) at the time of IDS) with patients achieving partial response (PR). This latter group was stratified by the presence of RD (RD = 0 vs RD > 0)., Results: Overall, 193 had IDS after neoadjuvant chemotherapy: 25 (13%), 81 (41.9%), and 74 (38.3%) patients had CR, PR with RD of 0, and PR with RD of more than 0, respectively. In addition, 13 (6.7%) patients had no macroscopic disease detected at DS but just microscopic disease at pathological examination. For the study purpose, 25 patients achieving CR were matched (1:2) with 50 patients having PR and RD of 0 and 50 patients having PR and RD of more than 0. As the result of propensity matching, baseline characteristics were similar between groups. Comparing survival outcomes of patients having CR and PR with RD of 0, we observed that type of response to chemotherapy did not influence disease-free (hazard ratio = 1.53 [95% confidence interval = 0.88-2.66], P = 0.127) and overall (hazard ratio = 1.74 [95% confidence interval = 0.76-4.01], P = 0.189) survivals. Patients achieving CR experienced significantly better disease-free survival (P = 0.004) and a trend toward better overall survival (P = 0.06) than patients achieving PR with RD of more than 0 at IDS., Conclusions: Complete cytoreduction might mitigate the difference in response to neoadjuvant chemotherapy. The presence of RD at IDS is associated with worse survival outcomes.

Objective: Pelvic exenteration for recurrent gynecological malignancies is characterized by a high rate of severe complications. Factors predictive of morbidity, readmission, and cost were analyzed., Methods: Data of consecutive patients undergoing pelvic exenteration between January 2007 and December 2016 were prospectively evaluated., Results: Fifty-eight patients were included in the analysis. Anterior, posterior, and total exenterations were executed in 39 (67%), 9 (16%), and 10 (17%) patients, respectively. Ten (15.5%) severe complications occurred: 8 (20.5%), 0 (0%), and 1 (10%) after anterior, posterior, and total exenterations, respectively. Radiotherapy dosage, time between radiotherapy and surgery, and previous administration of chemotherapy did not influence 90-day complications and readmission. At multivariable analysis, albumin levels less than 3.5 g/dL (odds ratio, 16.2 [95% confidence interval, 2.85-92.8]; P = 0.002) and history of deep vein thrombosis (odds ratio, 9.6 [95% confidence interval, 0.93-98.2]; P = 0.057) were associated with 90-day morbidity. Low albumin levels independently correlated with readmission (P = 0.011). The occurrence of 90-day postoperative complications and readmission increased costs of a median of +12,500 and +6000 euros, respectively (P < 0.05)., Conclusions: Preoperative patient selection is a key point for the reduction of postoperative complications after pelvic exenteration. Further prospective studies are warranted to improve patient selection.

Objective: Extramammary Paget disease of the vulva (EPDV) is a rare occurrence with an indolent and relapsing course. Progression to invasion occurs in 4% to 19% of cases. The aim of this study is to report clinical-pathological features and outcomes of patients treated for invasive EPDV., Methods: Data of consecutive patients treated between 2000 and 2017 for invasive EPDV were reviewed., Results: Among 79 patients with EPDV, 10 (12.7%) presented a microinvasive or invasive form at first diagnosis or during follow-up. All of them underwent upfront radical surgery; 7 (70%) received subsequent radiotherapy, chemotherapy, or both. The mortality rate was 40%. The recurrence rate after treatment for invasive forms was 60%, with a mean time to first recurrence of 20 (range, 5-36) months., Conclusions: Our study confirms that invasive EPDV remains a rare gynecological neoplasm with a poor prognosis. Multicentre trials or well-organized prospective data collection could improve the knowledge about the management of invasive EPDV.

Objectives: Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) may be a valuable treatment option in advanced ovarian cancer when primary cytoreduction is not feasible. However, a consensus on the ideal number of NACT cycles is still lacking. In the present investigation, we aimed to evaluate how number of cycles of NACT influenced patients' outcomes., Methods: Data of consecutive patients undergoing NACT and IDS were retrospectively reviewed in 4 Italian centers, and survival outcomes were evaluated., Results: Overall, 193 patients were included. Cycles of NACT were 3, 4, and at least 5 in 77 (40%), 74 (38%), and 43 (22%) patients, respectively. Patients undergoing 3 cycles experienced a similar disease-free survival (hazard ratio [HR], 1.12; 95% confidence interval [CI], 0.89-1.65; P = 0.20) but an improved overall survival (HR, 1.64; 95% CI, 1.05-2.4; P = 0.02) in comparison to patients receiving at least 4 cycles. Five-year overall survival was 46% and 31% for patients having 3 and at least 4 cycles. Ten-year overall survival was 26% and 18% for patients having 3 and at least 4 cycles (HR, 1.70; 95% CI, 1.13-2.55; P = 0.009). Using multivariate analysis, we observed that only Eastern Cooperative Oncology Group performance status correlated with overall survival (HR, 1.76; 95% CI, 1.2-2.49; P = 0.001). In addition, a trend toward worse overall survival was observed for patients with residual disease at IDS (HR, 1.29; 95% CI, 0.98-1.70; P = 0.06) and patients receiving at least 4 cycles (HR, 1.76; 95% CI, 0.95-3.22; P = 0.06)., Conclusion: Our data underline the potential implication of number of cycles of NACT before IDS. Further prospective studies are warranted to assess this correlation.

Objective: Transfusions represent one of the main progresses of modern medicine. However, accumulating evidence supports that transfusions correlate with worse survival outcomes in patients affected by solid cancers. In the present study, we aimed to investigate the effects of perioperative blood transfusion in locally advanced cervical cancer., Methods: Data of consecutive patients affected by locally advanced cervical cancer scheduled to undergo neoadjuvant chemotherapy plus radical surgery were retrospectively searched to test the impact of perioperative transfusions on survival outcomes. Five-year survival outcomes were evaluated using Kaplan-Meier and Cox models., Results: The study included 275 patients. Overall, 170 (62%) patients had blood transfusion. Via univariate analysis, we observed that transfusion correlated with an increased risk of developing recurrence (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.09-4.40; P = 0.02). Other factors associated with 5-year disease-free survival were noncomplete clinical response after neoadjuvant chemotherapy (HR, 2.99; 95% CI, 0.92-9.63; P = 0.06) and pathological (P = 0.03) response at neoadjuvant chemotherapy as well as parametrial (P = 0.004), vaginal (P < 0.001), and lymph node (P = 0.002) involvements. However, via multivariate analysis, only vaginal (HR, 3.07; 95% CI, 1.20-7.85; P = 0.01) and lymph node involvements (HR, 2.4; 95% CI, 1.00-6.06; P = 0.05) correlate with worse disease-free survival. No association with worse outcomes was observed for patients undergoing blood transfusion (HR, 2.71; 95% CI, 0.91-8.03; P = 0.07). Looking at factors influencing overall survival, we observed that lymph node status (P = 0.01) and vaginal involvement (P = 0.06) were independently associated with survival., Conclusions: The role of blood transfusions in increasing the risk of developing recurrence in LAAC patients treated by neoadjuvant chemotherapy plus radical surgery remains unclear; further prospective studies are warranted.

Objective: Optimal cytoreduction is one the main factors improving survival outcomes in patients affected by ovarian cancer (OC). It is estimated that approximately 40% of OC patients have gross disease located on the diaphragm. However, no mature data evaluating outcomes of surgical techniques for the management of diaphragmatic carcinosis exist. In the present study, we aimed to estimate surgery-related morbidity of different surgical techniques for diaphragmatic cytoreduction in advanced or recurrent OC., Methods: PubMed (MEDLINE), Web of Science, and Clincaltrials.gov databases were searched for records estimating outcomes of diaphragmatic peritoneal stripping (DPS) or diaphragmatic full-thickness resection (DFTR) for OC. The meta-analysis was performed using the Cochrane Review software., Results: For the final analysis, 5 articles were available, including 272 patients. Diaphragmatic peritoneal stripping and DFTR were performed in 197 patients (72%) and 75 patients (28%), respectively. Pooled analysis suggested that the estimated pleural effusion rate was 43% and 51% after DPS and DFTR, respectively. The need for pleural punctures or chest tube placement was 4% and 9% after DPS and DFTR, respectively. The rate of postoperative pneumothorax (4% vs 9%; odds ratio, 0.31; 95% confidence interval, 0.05-2.08) and subdiaphragmatic abscess (3% vs 3%; odds ratio, 0.45; 95% confidence interval, 0.09-2.31) were similar after the execution of DPS and DFTR., Conclusions: Diaphragmatic surgery is a crucial step during cytoreduction for advanced or recurrent OC. Obviously, the choice to perform DPS or DFTR depends on the infiltration of the diaphragmatic muscle or not. Both the procedures are associated with a low pulmonary complication and chest tube placement rates.

Background: Ovarian carcinosarcoma (OCS) is a rare malignancy associated with a poor prognosis. Platinum, anthracyclines, and alkylating agents are the most effective antiblastic drugs for treatment of gynecologic epithelial and stromal tumors. The aim of this study was to determine response rate and overall survival (OS) of patients with OCS who were treated with a combination of these 3 drugs., Methods: Forty-one women with OCS who were referred to the Department of Gynecologic Oncology of San Gerardo Hospital in Monza and European Institute of Oncology in Milan, between January 1995, and December 2006, and treated with a combination regimen of cisplatin, adriamycin, and cyclophosphamide or a combination regimen containing of cisplatin, epirubicin, and ifosfamide plus granulocyte colony-stimulating factor were considered for this study., Results: Four women had OCS stage I; 7, stage II; 23, stage III; and 7, stage IV. Heterologous, homologous, and mixed stromal components were described in 17, 14, and 10 patients, respectively. Thirteen women were treated with a combination of cisplatin, adriamycin, and cyclophosphamide and 28 with a combination of cisplatin, epirubicin, and ifosfamide plus granulocyte colony-stimulating factor. Two women did not complete their treatment because of the rapid progression of their disease and severe toxicity. Among 22 women considered evaluable for response, 10 (46%) achieved a complete response and 3 (13%) achieved a partial response (global response rate, 59%). Overall progression-free survival was 11.8 months (range, 0.9-96 months) and 13.8 and 10.1 months in stage I-II and III-IV, respectively (P = 0.13). Median OS was 20 months (range, 1-123 months), not reached in stage I-II, and 19.7 months in stage III-IV (P = 0.07). No significant difference between homologous and heterologous sarcomatous components was observed (P = 0.95), whereas no significant trend of improved OS was noticed for stage IIIC-IV with optimal debulking surgery (n = 9), compared with suboptimal cytoreduction (n = 19; 32.6 vs 14.5 months, P = 0.14)., Conclusion: The combination of anthracycline, alkylating agent, and cisplatin showed a good response rate but also a high toxicity. The prognosis of OCS remains poor. Optimal cytoreduction may improve survival, but new anticancer drugs or more effective regimens are awaited.
