RESUMO

BACKGROUND: Belzutifan is a first-in-class hypoxia-inducible factor subunit 2α (HIF-2α) inhibitor approved at a dose of 120 mg once daily for certain adults with VHL disease and adults with advanced renal cell carcinoma (RCC) following therapy with a programmed cell death protein 1 (PD-1) [or programmed death ligand 1 (PD-L1)] inhibitor and a vascular endothelial growth factor tyrosine kinase inhibitor. However, whether the belzutifan dose could be optimized is unclear. PATIENTS AND METHODS: The phase II LITESPARK-013 study (NCT04489771) enrolled patients with advanced clear cell RCC whose disease progressed after one to three prior systemic therapies, including an anti-PD-(L)1 regimen. Patients were randomly assigned 1 : 1 to receive belzutifan 120 or 200 mg once daily. The primary endpoint was the objective response rate (ORR) per RECIST version 1.1. The secondary endpoints were duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Overall, 154 patients were enrolled (120 mg: n = 76; 200 mg: n = 78). The median follow-up was 20.1 months (range 14.8-28.4). The ORR was 23.7% versus 23.1% for the 120 mg and 200 mg groups, respectively [P = 0.5312; -0.5%, 95% confidence interval (CI) -14.0% to 12.9%]. The median DOR was not reached for the 120 mg arm and was 16.1 months (2.1+ to 23.5+) for the 200 mg arm. No between-group differences were observed for PFS [hazard ratio (HR) 0.94, 95% CI 0.63-1.40] or OS (medians not reached; HR 1.11, 95% CI 0.65-1.90). Grade 3 or 4 treatment-related adverse events were observed in 35 patients (46.1%) in the 120 mg group and 36 patients (46.2%) in the 200 mg group. CONCLUSIONS: The efficacy of belzutifan was similar between the 120 mg dose and the 200 mg dose for previously treated clear cell RCC. Safety at both doses was consistent with the known safety profile of belzutifan. These results further support 120 mg once daily as the preferred dose for belzutifan.

RESUMO

BACKGROUND: In monarchE, abemaciclib plus endocrine therapy (ET) as adjuvant treatment of hormone receptor-positive, human epidermal growth factor 2-negative, high-risk, early breast cancer (EBC) demonstrated a clinically meaningful improvement in invasive disease-free survival versus ET alone. Detailed safety analyses conducted at a median follow-up of 27 months and key patient-reported outcomes (PROs) are presented. PATIENTS AND METHODS: The safety population included all patients who received at least one dose of study treatment (n = 5591). Safety analyses included incidence, management, and outcomes of common and clinically relevant adverse events (AEs). Patient-reported health-related quality of life, ET symptoms, fatigue, and side-effect burden were assessed. RESULTS: The addition of abemaciclib to ET resulted in higher incidence of grade ≥3 AEs (49.7% versus 16.3% with ET alone), predominantly laboratory cytopenias [e.g. neutropenia (19.6%)] without clinical complications. Abemaciclib-treated patients experienced more serious AEs (15.2% versus 8.8%). Discontinuation of abemaciclib and/or ET due to AEs occurred in 18.5% of patients, mainly due to grade 1/2 AEs (66.8%). AEs were managed with comedications (e.g. antidiarrheals), abemaciclib dose holds (61.7%), and/or dose reductions (43.4%). Diarrhea was generally low grade (grade 1/2: 76%); grade 2/3 events were highest in the first month (20.5%), most were short-lived (≤7 days) and did not recur. Venous thromboembolic events (VTEs) were higher with abemaciclib + ET (2.5%) versus ET (0.6%); in the abemaciclib arm, increased VTE risk was observed with tamoxifen versus aromatase inhibitors (4.3% versus 1.8%). PROs were similar between arms, including being 'bothered by side-effects of treatment', except for diarrhea. At ≥3 months, most patients reporting diarrhea reported 'a little bit' or 'somewhat'. CONCLUSIONS: In patients with high-risk EBC, adjuvant abemaciclib + ET has an acceptable safety profile and tolerability is supported by PRO findings. Most AEs were reversible and manageable with comedications and/or dose modifications, consistent with the known abemaciclib toxicity profile.

RESUMO

Human papillomavirus 16 (HPV16) infection is the aetiologic factor for the development of cervical dysplasia and is regarded as highly carcinogen, because it is implicated in more than 50% of cervical cancer cases, worldwide. The tumourigenic potential of HPV16 has triggered the extensive sequence analysis of viral genome in order to identify nucleotide variations and amino acid substitutions that influence viral oncogenicity and subsequently the initiation and progression of cervical cancer. Nowadays, specific mutations of HPV16 DNA have been associated with an increased risk of high-grade squamous intraepithelial lesions and invasive cervical cancer (ICC) development, including E6: Q14H, H78Y, L83V, Ε7: N29S, S63F, E2: H35Q, P219S, T310K, E5: I65V, whereas highly conserved regions of viral DNA have been extensively characterised. In addition, numerous novel HPV16 mutations are observed among the studied populations from various geographic regions, hence advocating that different HPV16 strains seem to emerge with different tumourigenic capacities. The present review focuses on the variability of the early genes and the long control region, emphasising on the association of specific mutations with the development of severe dysplasia. Finally, it evaluates whether specific regions of HPV16 DNA are able to serve as valuable biomarkers for cervical cancer risk.

RESUMO

PURPOSE: The efficacy of nab-paclitaxel in patients with metastatic breast cancer (MBC) has been demonstrated in randomized clinical trials. However, real-world evidence on effectiveness remains limited. PATIENTS AND METHODS: The primary objective of this multicenter prospective study was to assess the overall response rate (ORR) of patients with MBC treated with nab-paclitaxel. Secondary objectives included progression-free survival (PFS), overall survival (OS) and quality of life, assessed with the Functional Assessment of Cancer Therapy-Breast (FACT-B) instrument. RESULTS: Eligible patients (N = 150; 36% with de novo MBC presentation) with a median age of 64.5 years were enrolled (86% were ER+, 33.3% (50/150) were ≥ 70 years of age and 53% were treated in the third or later line of treatment). A median of 6 cycles were administered but 26% of patients required dose reduction due to toxicity. The ORR was 26.7% [95% confidence interval (CI) 19.6-33.7], the median PFS was 6.2 months (95% CI 5.2-7.3), and the median OS 21.1 months (95% CI 17.2-not estimable). There was no statistical significant difference in the median PFS of patients < and ≥ 70 years of age. The patients' baseline FACT-B total score remained unchanged. The serious and non-serious adverse event incidence rates were 13% and 48%, respectively. CONCLUSIONS: This prospective study provides further evidence on quality of life, efficacy, and safety of nab-paclitaxel in patients with MBC and sheds more light in special subpopulations such as the elderly and those treated beyond the second line.

RESUMO

BACKGROUND: Kidney cancer is a lethal neoplasm that affects several thousands of people every year. Renal cell carcinoma (RCC) is the most common histologic type. Recent developments in the therapeutic approach include antiangiogenic targeted approaches and Immunotherapy. Thus, the therapeutic algorithm of RCC patients and the survival outcomes have changed dramatically. METHODS: Herein we present a retrospective study of the patients treated in our Department with an antiangiogenic agent -Axitinib, a tyrosine kinase inhibitor- as a third or further line treatment. Statistical analysis was performed with SPSS, including the available clinicopathological data of the patients included. RESULTS: Axitinib was found to be active in patients who received this treatment beyond second line. The toxicity profile of this regimen did not reveal any unknown adverse events. CONCLUSIONS: Our real world data reflect that axitinib is a safe and effective option, even beyond the second line.

RESUMO

We aimed to provide comprehensive protocols and promote effective management of pregnant women with gynecological cancers. New insights and more experience have been gained since the previous guidelines were published in 2014. Members of the International Network on Cancer, Infertility and Pregnancy (INCIP), in collaboration with other international experts, reviewed existing literature on their respective areas of expertise. Summaries were subsequently merged into a manuscript that served as a basis for discussion during the consensus meeting. Treatment of gynecological cancers during pregnancy is attainable if management is achieved by collaboration of a multidisciplinary team of health care providers. This allows further optimization of maternal treatment, while considering fetal development and providing psychological support and long-term follow-up of the infants. Nonionizing imaging procedures are preferred diagnostic procedures, but limited ionizing imaging methods can be allowed if indispensable for treatment plans. In contrast to other cancers, standard surgery for gynecological cancers often needs to be adapted according to cancer type and gestational age. Most standard regimens of chemotherapy can be administered after 14 weeks gestational age but are not recommended beyond 35 weeks. C-section is recommended for most cervical and vulvar cancers, whereas vaginal delivery is allowed in most ovarian cancers. Breast-feeding should be avoided with ongoing chemotherapeutic, endocrine or targeted treatment. More studies that focus on the long-term toxic effects of gynecologic cancer treatments are needed to provide a full understanding of their fetal impact. In particular, data on targeted therapies that are becoming standard of care in certain gynecological malignancies is still limited. Furthermore, more studies aimed at the definition of the exact prognosis of patients after antenatal cancer treatment are warranted. Participation in existing registries (www.cancerinpregnancy.org) and the creation of national tumor boards with multidisciplinary teams of care providers (supplementary Box S1, available at Annals of Oncology online) is encouraged.

RESUMO

BACKGROUND: In the open-label randomized phase III AURELIA trial, adding bevacizumab to chemotherapy for platinum-resistant ovarian cancer (PROC) significantly improved progression-free survival and response rate versus chemotherapy alone, but not overall survival (OS). We explored the effect of bevacizumab use after disease progression (PD) in patients randomized to chemotherapy alone. PATIENTS AND METHODS: In AURELIA, 361 women with PROC were randomized to chemotherapy alone or with bevacizumab. Patients initially randomized to chemotherapy were offered bevacizumab after PD. Post hoc analyses assessed efficacy and safety in three subgroups: chemotherapy alone, chemotherapy followed by bevacizumab after PD, and chemotherapy plus bevacizumab at randomization. RESULTS: Of the 182 patients randomized to chemotherapy alone, 72 (40%) received bevacizumab after PD and 110 (60%) never received bevacizumab. There were no significant differences in patient and disease characteristics between these subgroups at baseline or the time of PD. Compared with patients never receiving bevacizumab, the risk of death was significantly reduced in patients receiving bevacizumab either upfront with chemotherapy [hazard ratio (HR) = 0.68, 95% confidence interval (CI) 0.52-0.90] or after PD (HR = 0.60, 95% CI 0.43-0.86). The tolerability of bevacizumab was similar with administration upfront or after PD. CONCLUSIONS: Post-PD bevacizumab use may have confounded OS results in AURELIA. In these exploratory analyses of non-randomized subgroups, bevacizumab use, either with chemotherapy or after PD on chemotherapy alone, improved OS compared with no bevacizumab. Combining bevacizumab with chemotherapy at first appearance of platinum resistance maximises the likelihood of patients receiving this active treatment for PROC. ClinicalTrials.gov: NCT00976911.

RESUMO

BACKGROUND: Progression-free survival (PFS), objective response rate (ORR), and patient-reported outcomes (PROs) were significantly improved by adding bevacizumab to chemotherapy for platinum-resistant ovarian cancer (PROC) in the phase III AURELIA trial. We explored treatment outcomes according to primary platinum resistance (PPR) versus secondary platinum resistance (SPR). PATIENTS AND METHODS: Patients were categorized as PPR (disease progression <6 months after completing first-line platinum therapy) or SPR (progression ≥6 months after first platinum but <6 months after second). The exploratory Cox and logistic regression analyses correlated PFS, ORR, overall survival (OS), and PROs with the time to development of platinum resistance. RESULTS: Baseline characteristics were similar in patients with PPR (n = 262; 73%) and SPR (n = 99; 27%), although ascites were more common in the PPR subgroup. In bevacizumab-treated patients (n = 179), SPR was associated with improved PFS (median 10.2 versus 5.6 months in PPR patients; P < 0.001) and OS (median 22.2 versus 13.7 months, respectively; P < 0.001) but not PROs (22% versus 22% with improved abdominal/gastrointestinal symptoms at week 8/9). In multivariate analyses, SPR remained an independent prognostic factor for better PFS [adjusted hazard ratio (HR) 0.41, 95% confidence interval (CI) 0.25-0.67; P < 0.001] and OS (HR 0.49, 95% CI 0.30-0.80; P = 0.005) in bevacizumab-treated patients, but was not statistically significant for either end point in the chemotherapy-alone subgroup. The magnitude of PFS benefit from bevacizumab appeared greater in SPR than PPR patients (HR 0.30 versus 0.55, respectively; interaction P = 0.07) with a similar direction of effect for OS (interaction P = 0.18). CONCLUSIONS: In bevacizumab-treated patients, PFS and OS were more favorable in SPR than PPR patients with equally improved PROs. The PFS and OS benefit from combining bevacizumab with chemotherapy was more pronounced in SPR than PPR PROC. PPR versus SPR should be a stratification factor in future trials evaluating anti-angiogenic therapy for PROC.

RESUMO

The aim of the study was to evaluate the association of vascular endothelial growth factor (VEGF) genotypes with treatment efficacy in a phase II trial. This study evaluated weekly docetaxel, as first-line treatment for metastatic breast cancer. Existing data from in vitro and animal model experiments suggest that docetaxel at low doses has anti-angiogenic activity. DNA was extracted from blood samples of 86 patients participating in the trial. Genotyping was performed for selected single-nucleotide polymorphisms (SNPs; VEGF-2578, -1498, -1154, and +936). Moreover, due to the highly polymorphic nature of the studied areas, we were able to analyze additional registered SNPs. All candidate genotypes were evaluated for associations with overall survival (OS), progression-free survival (PFS) and response rate. The VEGF-1154 GG genotype was more frequent in patients not responding to treatment compared with responders (42.9% vs 0.0%, P=0.048). Moreover, the VEGF-2578 AA genotype was associated with longer PFS compared with CC (hazard ratio (HR)=0.40; 95% confidence interval (CI) 0.17-0.98; pairwise P=0.0457). Patients with the VEGF-1190 GG genotype demonstrated shorter PFS compared with those with the alternative genotypes (GA and AA) combined (HR=3.85; 95% CI: 1.20-12.50; P=0.0224). In addition, the VEGF-2551/-2534 homozygous del18bp and VEGF-2430/-2425 homozygous ins1bp genotypes were associated with worse PFS compared with no deletion and no insertion, respectively (HR=2.49; 95% CI: 1.02-6.07; pairwise P=0.0442 and HR=2.57; 95% CI: 1.05-6.27; pairwise P=0.0385, respectively). Furthermore, patients with the VEGF-1498 CC genotype exhibited longer median OS compared with those with the alternatives genotypes (CT and TT) combined (HR=0.27; 95% CI: 0.08-0.89; P=0.0311). In multivariate analysis, the VEGF-2578 AA genotype retained its significance (P=0.0220) for PFS. Our results support the association of specific VEGF genotypes with clinical outcome in patients with metastatic breast cancer treated with a potentially anti-angiogenic regimen, such as weekly docetaxel. However, current results should be validated prospectively in larger cohorts.

RESUMO

INTRODUCTION: Real-world data on management of metastatic castration resistant prostate cancer (mCRPC) with novel therapies is sparse. The aim of this study was to capture real-world management strategies in patients with mCRPC who initiated first line (1L) systemic therapy with chemotherapy or novel hormonal agents (NHAs) in Greece and describe the therapeutic sequencing strategy among patients who advanced to 2L and 3L treatment. PATIENTS AND METHODS: In this noninterventional, multicentre, retrospective study (PROSPECT), a medical chart review of 149 patients with mCRPC who initiated 1L systemic therapy with chemotherapy or NHAs in 7 major anticancer hospital clinics, from public, academic, and private sectors in Greece was conducted. All endpoints were descriptively analysed. Kaplan-Meier was used for time-to-event outcomes. RESULTS: At 1L (N = 149), most (78.5%) patients received NHAs; enzalutamide (52.3%), and abiraterone (26.2%). At 2L (N = 68), most (72.1%) patients received chemotherapy, most frequently docetaxel (50.0% of all patients). At 3L (N = 32), 56.3% and 31.3% of patients received chemotherapy and NHAs, respectively. Regarding treatment sequencing from 1L→2L (N = 68), most patients (55.9%) advanced from NHA→chemotherapy. Regarding treatment sequencing from 1L→2L→3L (N = 32), 34.4% advanced from NHAs→chemotherapy→chemotherapy and 31.3% from NHAs→chemotherapy→NHA. Estimated median times spent on treatment at 1L, 2L, and 3L were 9.8, 4.4, and 3.7 months, respectively. CONCLUSION: Most patients were treated with 1L NHAs, in accordance to established guidelines (which suggest both NHA and chemo as preferred 1st line options). There appeared to be a longer time on treatment of NHAs at 1L than chemotherapy, suggesting an unmet need for treatment optimisation/recommendations for 2L and 3L treatment in mCRPC.

RESUMO

BACKGROUND: Data regarding the safety and effectiveness of aromatase inhibitors (AIs) as monotherapy or combined with gonadotropin-releasing hormone (GnRH) analogue in male breast cancer are scarce. METHODS: In this retrospective chart review, cases of male breast cancer patients treated with AIs with or without a GnRH analogue were evaluated. RESULTS: Twenty-three men were included into this case series. Aromatase inhibitors in combination with or without a GnRH analogue were given as first-line therapy in 60.9% and as second-line therapy in 39.1% of patients, respectively. All patients had visceral metastases, whereas in five of them bone lesions coexisted. In all cases AIs were tolerated well, and no case of grade 3 and 4 adverse events was reported. A partial response was observed in 26.1% of patients and stable disease in 56.5%. Median overall survival (OS) was 39 months and median progression-free survival (PFS) was 13 months. Regarding OS and PFS, no significant effects of GnRH analogue co-administration or type of AI were noted. CONCLUSION: Our study shows that AIs with or without GnRH analogues may represent an effective and safe treatment option for hormone-receptor positive, pretreated, metastatic, male breast cancer patients.

RESUMO

BACKGROUND: The mesenchymal-epithelial transition (MET) pathway is frequently altered in tumours. The purpose of our study was to determine the prognostic value of tumour MET expression levels in patients with triple-negative breast cancer (TNBC), in order to strengthen the rationale for targeted therapy of TNBC using MET inhibitors. METHODS: We determined expression of MET in formalin-fixed paraffin-embedded surgical specimens of TNBC by immunohistochemistry. Recurrence-free and overall survival was analysed with Cox models adjusted for clinical and pathological factors. RESULTS: Immunostaining for MET was classified as high in 89 of 170 (52%) tumours. MET expression was more frequently observed in G3 carcinomas (P=0.02) but was not significantly associated to any of the other clinical or pathological parameters. High MET expression predicted shorter survival of the patients. Multivariate Cox proportional hazards regression analyses identified MET to be an independent prognostic factor for recurrence (adjusted hazard ratio (HR) for recurrence 3.43; 95% confidence interval (CI) 1.65-7.12; P=0.001) and death (adjusted HR for death 3.74; 95% CI 1.65-8.46; P=0.002). CONCLUSION: These results provide further evidence that the MET pathway could be exploited as a target for TNBC.

RESUMO

BACKGROUND: We critically evaluated the available evidence on genomic tests in breast cancer to define their prognostic ability and likelihood to determine treatment benefit. DESIGN: Independent evaluation of six genomic tests [Oncotype Dx™, MammaPrint(®), Genomic Grade Index, PAM50 (ROR-S), Breast Cancer Index, and EndoPredict] was carried out by a panel of experts in three parameters: analytical validity, clinical validity, and clinical utility based on the principles of the EGAPP criteria. PANEL STATEMENTS: The majority of the working group members found the available evidence on the analytical and clinical validity of Oncotype Dx™ and MammaPrint(®) to be convincing. None of the genomic tests demonstrated robust evidence of clinical utility: it was not clear from the current evidence that modifying treatment decisions based on the results of a given genomic test could result in improving clinical outcome. CONCLUSIONS: The IMPAKT 2012 Working Group proposed the following recommendations: (i) a need to develop models that integrate clinicopathologic factors along with genomic tests; (ii) demonstration of clinical utility should be made in the context of a prospective randomized trial; and (iii) the creation of registries for patients who are subjected to genomic testing in the daily practice.

RESUMO

PURPOSE: Contradictory results have been reported concerning the role of maspin and its cellular distribution in breast cancer. The purpose of this study was to examine the subcellular localization (nuclear-cytoplasmic) of maspin in breast cancer and to compare the evaluation of maspin immunostaining via light microscopy (LM) to the estimation via computerized image analysis (CIA) system. We also examined correlations between maspin expression and several clinicopathological parameters. METHODS: The sample consisted of 48 primary invasive ductal carcinomas (IDC) of the breast. Maspin immunostaining was quantified and graded via LM by two pathologists, separately in the nuclear and cytoplasmic compartments. Total maspin expression was also estimated via CIA system. Univariate non-parametric statistics and stepwise multivariate ordinal logistic regression were performed. RESULTS: Both maspin components (nuclear and cytoplasmic) were closely associated with each other (p<0.001). Total maspin score was positively and closely associated with nuclear maspin (p<0.001) and cytoplasmic maspin (p<0.001). Total maspin , nuclear maspin and cytoplasmic maspin did not correlate significantly with either age, grade, T, N and M status, stage, micro vessel density (MVD) (CD34), ki-67, p53, estrogen receptor (ER) and HER-2 status, or with any of the 4 groups of the molecular classification. The only factor that showed a borderline inverse correlation with nuclear maspin (p=0.059) was progesterone receptors (PR) positivity. CONCLUSION: The cytoplasmic and nuclear fractions of maspin seem to be closely interwoven. Evidently, both mutually intertwined counterparts were independently reflected upon the total maspin levels measured by CIA. Future studies should ideally encompass all three approaches (nuclear, cytoplasmic, total) adopted herein.

RESUMO

OBJECTIVE: Early-stage epithelial ovarian cancer represents a prognostically heterogenous group. We studied prognostic factors in patients treated with adjuvant paclitaxel/carboplatin chemotherapy. METHODS: Data was extracted from 147 patients with FIGO stage IA/IB, grade 2/3 or stage IC/IIA (any grade) who underwent primary surgery followed by paclitaxel/carboplatin chemotherapy. RESULTS: Median follow-up was 88 months. Ten-year relapse-free (RFS) and disease-specific survival (DSS) were: 81% (95% confidence interval [CI]: 73-89) and 81% (95% CI: 73-89). On multivariate analysis, non serous histology was associated with reduced risk for RFS (0.294, 95% CI: 0.112-0.577, p=0.001) and DSS (0.194, 95% CI: 0.075-0.504, p=0.001), while high-risk category (stage IC/IIA and grade 2/3) with increased risk for RFS (3.989, 95% CI: 1.189-13.389, p=0.009) and DSS (3.989, 95% CI: 1.064-16.386, p=0.038). The combination of histology and grade identified 3 groups with distinctly different 10-year RFS and DSS rates (p<0.001): grade 1 (100% and 100%), non-serous grade 2/3 (83% and 86%) and serous grade 2/3 (60% and 60%). CONCLUSIONS: Serous histology is an adverse prognostic factor in early-stage ovarian cancer treated with adjuvant paclitaxel/carboplatin. Risk stratification according to histology and grade is a useful discriminator of prognosis and can be used in the design of future studies.

RESUMO

BACKGROUND: The use of laparoscopic surgery in gynecologic oncology might be complicated by unsuspected side-effects for the patient. Experimental data suggest that the risk of tumor dissemination in the non traumatized peritoneum may be higher after pneumoperitoneum than after laparotomy, and they also show the importance of the surgeon's experience and technique. CASES: We present two cases of uterine endometrial stromal tumors which were laparoscopically excised. In both cases, intraperitoneal tumor seedings were identified shortly after the initial operation. The first patient had a low-grade endometrial stromal sarcoma and succumbed from the disease two years after the initial operation, while the second patient who was diagnosed with endometrial stromal tumor remains disease free two years later. CONCLUSIONS: The laparoscopic excision of an endometrial stromal tumor might result in tumor dissemination into the abdominal cavity. A careful second-look examination of the abdomen or a radical surgical approach is proposed.

RESUMO

BACKGROUND: Immune checkpoint inhibitors have been widely implemented in current clinical practice. Although cancer occurs in ∼1 out of 1000 pregnancies, treatment remains challenging. Until now, limited data exist regarding immunotherapy administration during pregnancy. This systemic review aims to synthesize all available data from immunotherapy administration in pregnant women and evaluate the efficacy and safety of immunotherapy during pregnancy. PATIENTS AND METHODS: Eligible studies were identified by a search of the PubMed Medline database and Food and Drug Administration Adverse Events Reporting System Public Dashboard for the period 1 January 2000 to 1 April 2021; the algorithm consisted of a predefined combination of the words 'immunotherapy', 'cancer' and 'pregnancy'. PRISMA guidelines were applied in this study. RESULTS: Overall, seven articles (seven pregnancies, nine neonates) were retrieved. The mean duration of immunotherapy administration was 9.8 weeks [standard deviation (SD): 11.27; median: 7.0; range: 1-32]. In all cases specified, melanoma was the malignancy reported. The mean gestational age at delivery was 30.4 weeks (SD: 5.03; median: 32.0; range: 24-38), whereas the mean weight of neonates at delivery was 1267 g (SD: 412.0; median: 1400; range: 590-1701). Only one neonate was born term at 38 weeks of pregnancy (11.1%; 1/9). Complications during pregnancy were observed in 71.4% of cases: intrauterine growth restriction (three cases), HELLP syndrome (hemolysis, elevated liver enzymes, low platelet count) (one case), placental insufficiency (one case) and low fetal heart rate (one case). The mean progression-free survival and overall survival were 16.0 and 25.2 months, respectively. CONCLUSION: The administration of immune checkpoint inhibitors during pregnancy is associated with increased incidence of pregnancy complications, prematurity and low birth weight. The administration of these regimens is not recommended during gestation. Whenever applied, close monitoring of the mother and the fetus is required.

RESUMO

Immune checkpoint inhibitors (ICIs) are antibodies that target certain immune checkpoints (ICs), such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), programmed death 1 (PD-1) or its ligand (PD-L1), and have emerged as a powerful new tool for oncologists. As these immune checkpoints are crucial for immunological self-tolerance, such therapies can trigger autoimmune adverse effects. Endocrine complications are among the most common, including hypophysitis, thyroid dysfunction, diabetes mellitus and primary adrenal insufficiency, while autoimmune polyendocrine syndrome type 2 (APS-2) may also present. The aim of this article is to critically appraise the literature and present (i) the biological role and function of the main ICs, (ii) the use of ICIs in the treatment of various cancer types, (iii) the endocrine complications of cancer immunotherapy with ICIs and (iv) practical recommendations for screening and management of patients with such endocrinopathies in everyday clinical practice.

RESUMO

BACKGROUND: Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) is the recommended approach in patients with advanced epithelial ovarian cancer (EOC). However, most patients eventually relapse despite the initial high response rate to chemotherapy. Neutrophil-to-lymphocyte ratio is a well-known biomarker that reflects severe inflammation, critical illness, and mortality in various diseases. Chemotherapy response score (CRS) and neutrophil-to-lymphocyte ratio (NLR) have been identified as potential biomarkers of platinum resistance and disease prognosis. We retrospectively evaluated 132 patients with stage IIIc or IV ovarian/fallopian tube/primary peritoneal cancer who had received NACT followed by IDS from 01/01/2003 to 31/12/2018. CRS was assessed on omental specimens collected from IDS according to ICCR guidelines. RESULTS: Median age was 64.57 years (SD: 9.72; range 39.2-87.1). Most ovarian tumors were serous epithelial (90.9%; 120/132). An elevated NLR (defined as > 3) was observed in 72% (95/132) of patients in contrast with 28% (37/132) of patients characterized by low NLR status. Median PFS (mPFS) and median overall survival (mOS) were 13.05 months (95% CI: 11.42-14.67)) and 34.69 months (95% CI: 23.26-46.12) respectively. In univariate analysis, CRS3 score was significantly associated with prolonged mPFS (CRS1/2: 12.79 months vs CRS3: 17.7 months; P = 0.008). CRS score was not associated with mOS (P = 0.876). High NLR was not significantly associated with mPFS (P = 0.128), however it was significantly associated with poor mOS (P = 0.012). In multivariate analysis, only performance of surgery maintained its statistical significance with both PFS (P = 0.001) and OS (P = 0.008). CONCLUSION: NLR could serve as a useful predictor of OS but not PFS in ovarian cancer patients receiving NACT. In accordance with our previous study, CRS score at omentum was found to be associated with PFS but not OS in ovarian cancer patients treated with NACT and IDS.


Biomarkers that would predict response to neoadjuvant chemotherapy in advanced ovarian cancer patients are eagerly needed:• Neutrophil to Lymphocyte Ratio (NLR) is an indicator of systemic inflammatory response to the malignancy.• NLR was evaluated in 132 patients undergoing Neoadjuvant Chemotherapy for advanced ovarian cancer.• Elevated NLR was associated with worse prognosis.• No association between NLR and response to chemotherapy was noted.
