RESUMEN

OBJECTIVE: The objective of this systematic review was to evaluate the effect of different types of neoadjuvant chemotherapy regimens, in terms of optimal pathological response and oncological outcomes, in patients with locally advanced cervical cancer. METHODS: A systematic search of the literature was performed. MEDLINE through PubMed and Embase databases were searched from inception to June 2023. The study was registered in PROSPERO (ID number CRD42023389806). All women with a pathological diagnosis of locally advanced cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009 classification stages IB2-IVA), any age or histology, who underwent intravenous neoadjuvant chemotherapy before radical surgery, and articles only in English language, were included. We conducted a meta-analysis for optimal pathological response after surgery and survival outcomes. The risk of bias was assessed using the Newcastle-Ottawa scale and the Risk of Bias 2 (RoB) tools. The review methods and results were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: 25 studies with a total number of 1984 patients fulfilled the eligibility criteria of our review and were included for data extraction and efficacy analysis. When compared with a two-drug regimen, the three-drug combination including cisplatin, paclitaxel, and ifosfamide or anthracyclines showed superior efficacy in terms of optimal pathological response with an odds ratio of 0.38 (95% CI 0.24 to 0.61, p<0.0001), with no difference in disease-free survival (hazard ratio (HR) 0.72, 95% CI 0.50 to 1.03, I2=0%, p=0.07) and higher overall survival (HR 0.63, 95% CI 0.41 to 0.97, I2=0%, p=0.03). CONCLUSIONS: The three-drug combination of cisplatin, paclitaxel, and ifosfamide or anthracyclines showed a higher rate of complete or optimal partial response, with the triple regimens having an advantage over the platinum-based schedules in terms of overall survival. Neoadjuvant chemotherapy followed by radical surgery should not be considered a standard of care in locally advanced cervical cancer.

RESUMEN

INTRODUCTION: It is essential to choose a realistic anticipated intervention effect when calculating a sample size for a randomised clinical trial. Unfortunately, anticipated intervention effects are often inflated, when compared with the 'true' intervention effects. This is documented for mortality in critical care trials. A similar pattern might exist across different medical specialties. This study aims to estimate the range of observed intervention effects for all-cause mortality in trials included in Cochrane Reviews, within each Cochrane Review Group. METHODS AND ANALYSIS: We will include randomised clinical trials assessing all-cause mortality as an outcome. Trials will be identified from Cochrane Reviews published in the Cochrane Database of Systematic Reviews. Cochrane Reviews will be clustered according to the registered Cochrane Review Group (eg, Anaesthesia, Emergency and Critical Care) and the statistical analyses will be conducted for each Cochrane Review Group and overall. The median relative risk and IQR for all-cause mortality and the proportion of trials with a relative all-cause mortality risk within seven different ranges will be reported (relative risk below 0.70, 0.70-0.79, 0.80-0.89, 0.90-1.09, 1.10-1.19, 1.20-1.30 and above 1.30). Subgroup analyses will explore the effects of original design, sample size, risk of bias, disease, intervention type, follow-up length, participating centres, funding type, information size and outcome hierarchy. ETHICS AND DISSEMINATION: Since we will use summary data from trials already approved by relevant ethical committees, this study does not require ethical approval. Regardless of our findings, the results will be published in an international peer-reviewed journal.

RESUMEN

Pharmacogenomics studies how genes influence a person's response to treatment. When complex phenotypes are influenced by multiple genetic variations with little effect, a single piece of genetic information is often insufficient to explain this variability. The application of machine learning (ML) in pharmacogenomics holds great potential - namely, it can be used to unravel complicated genetic relationships that could explain response to therapy. In this study, ML techniques were used to investigate the relationship between genetic variations affecting more than 60 candidate genes and carboplatin-induced, taxane-induced, and bevacizumab-induced toxicities in 171 patients with ovarian cancer enrolled in the MITO-16A/MaNGO-OV2A trial. Single-nucleotide variation (SNV, formerly SNP) profiles were examined using ML to find and prioritize those associated with drug-induced toxicities, specifically hypertension, hematological toxicity, nonhematological toxicity, and proteinuria. The Boruta algorithm was used in cross-validation to determine the significance of SNVs in predicting toxicities. Important SNVs were then used to train eXtreme gradient boosting models. During cross-validation, the models achieved reliable performance with a Matthews correlation coefficient ranging from 0.375 to 0.410. A total of 43 SNVs critical for predicting toxicity were identified. For each toxicity, key SNVs were used to create a polygenic toxicity risk score that effectively divided individuals into high-risk and low-risk categories. In particular, compared with low-risk individuals, high-risk patients were 28-fold more likely to develop hypertension. The proposed method provided insightful data to improve precision medicine for patients with ovarian cancer, which may be useful for reducing toxicities and improving toxicity management.

RESUMEN

When conducting randomised clinical trials, the choice of methodology and statistical analyses will influence the results. If the planned methodology is not of optimal quality and predefined in detail, there is a risk of biased trial results and interpretation. Even though clinical trial methodology is already at a very high standard, there are many trials that deliver biased results due to the implementation of inadequate methodology, poor data quality and erroneous or biased analyses. To increase the internal and external validity of randomised clinical trial results, several international institutions within clinical intervention research have formed The Centre for Statistical and Methodological Excellence (CESAME). Based on international consensus, the CESAME initiative will develop recommendations for the proper methodological planning, conduct and analysis of clinical intervention research. CESAME aims to increase the validity of randomised clinical trial results which will ultimately benefit patients worldwide across medical specialities. The work of CESAME will be performed within 3 closely interconnected pillars: (1) planning randomised clinical trials; (2) conducting randomised clinical trials; and (3) analysing randomised clinical trials.

RESUMEN

BACKGROUND: Previous findings showed that cediranib-olaparib increased PFS in women with recurrent platinum-sensitive ovarian cancer compared to olaparib alone. METHODS: BAROCCO trial randomized 123 patients: 80mg/m2 paclitaxel weekly up to 24 weeks (control), olaparib 300mg tablets twice daily together with 20mg cediranib daily (continuous schedule) or with 20mg cediranib 5 days/week (intermittent schedule) until progression. The primary objective was the PFS comparison between each experimental arm and the control (alpha one-sided 5%; power 80%; HR 0.5). RESULTS: The median platinum-free interval was 1.9 months, 60% of patients had been pretreated with 3 or more chemotherapy lines. Median PFS for paclitaxel, the continuous, and the intermittent schedules were 3.1, 5.6, and 3.8 months. The HR for PFS in the continuous arm vs control was 0.76 (90% CI: 0.50-1.14, p = 0.265). The HR for PFS in the intermittent arm vs control was 1.03 (90% CI: 0.68-1.55, p = 0.904). Treatment was discontinued due to adverse events in 15%, 20%, and 5% of patients in the control, continuous and intermittent arms. Grade ≥ 3 anemia and diarrhea and hypertension of any grade occurred only in the experimental arms, and peripheral neuropathies and alopecia only in the control arm. Five serious adverse drug reactions occurred and two were fatal: one in the control and one in the continuous arm. CONCLUSIONS: The combination of cediranib-olaparib was not superior to chemotherapy in terms of PFS in heavily pretreated platinum-resistant ovarian cancer patients. However, this oral doublet, is active and may offer a non-chemotherapy option in this difficult to treat population.

RESUMEN

PRECIS: Central corneal thickness (CCT) may increase over time in children affected by primary congenital glaucoma and treated with latanoprost for at least 30 months. PURPOSE: The purpose of this study was to investigate CCT modification over time in a population of primary pediatric glaucoma (PPG) patients prescribed a monotherapy of latanoprost. MATERIALS AND METHODS: The present paper reports the results of a post hoc analysis on patients enrolled in the Glaucoma Italian Pediatric Study (GIPSy). Children affected by PPG, with a postsurgical intraocular pressure between 22 and 26 mm Hg and treated with latanoprost monotherapy for at least 30 months were eligible for the analysis. CCT variation from baseline was investigated over the follow-up using univariable and multivariable longitudinal linear mixed models. The impact of age, sex, and intraocular pressure on CCT variation were evaluated taking into account the interaction of each variable with time. RESULTS: Twenty-seven eyes (20 patients) were included in the analysis. Mean duration of latanoprost treatment was 36.6 months (SD 2.5) and mean CCT at baseline was 551 µm (SD 37.7). A significant increase of CCT over time was revealed by multivariable analysis, taking into account the impact of age at baseline and its interaction with time (P=0.03). The interaction between age and time was significant (P=0.04), indicating that older age at baseline was associated with lower increase of CCT over time. No variation of CCT was found in univariable analysis (P=0.28). CONCLUSION: In this population of PPG patients treated with latanoprost for at least 30 months, CCT significantly increased over time, when the impact of age and its interaction with time were considered.

RESUMEN

OBJECTIVE: This meta-analysis investigated the effectiveness of PARP inhibitors (PARPis) as maintenance treatment in platinum sensitive recurrent ovarian cancer (ROC), stratifying results based on BRCA mutational status into five different categories: whole population, germ-line BRCA mutated patients, somatic BRCA mutated patients, HRD patients and wild type population. METHODS: PubMed, Medline, Scopus, EMBASE and clinicaltrials.gov, as well as meeting proceedings were searched for eligible studies that described RCTs testing the efficacy of PARPis as maintenance treatment in platinum sensitive ROC. Data were extracted independently and analysed using RevMan statistical software version 5.3. Primary end-point was progression free survival (PFS). RESULTS: The analysis confirmed the positive effect of PARPis in patients with platinum sensitive ROC in case of germinal or somatic BRCA mutations. Specifically, HR for PFS was 0.26, 95% CI 0.21-0.31, p < 0.00001 for the mutation of BRCA gene and 0.24, 95%, CI 0.12-0.48, p < 0.0001 for the somatic alteration. In addition, in the HRD population, studies that analysed the efficacy of PARPis  reported a PFS improvement with HR 0.34, 95% CI 0.26-0.43, p < 0.00001. Finally, our analysis confirms the role of these drugs in prolonging PFS in the whole population with HR 0.36, 95% CI 0.32-0.42, p < 0.00001, although to a lesser extent, with a significant improvement even in wild type cancers with HR 0.49, 95%, CI 0.41-0.59, p < 0.00001). CONCLUSIONS: PARPis are effective regardless of BRCA mutational status. Future investigations are necessary to explore the use of different PARPis as monotherapy, comparing them among each other in terms of efficacy and toxicity, and exploring their potential re-use.

RESUMEN

BACKGROUND: Trabectedin, in addition to its antiproliferative effect, can modify the tumour microenvironment and this could be synergistic with bevacizumab. The efficacy and safety of trabectedin and bevacizumab ± carboplatin have never been investigated. METHODS: In this phase 2 study, women progressing between 6 and 12 months since their last platinum-based therapy were randomised to Arm BT: bevacizumab, trabectedin every 21 days, or Arm BT+C: bevacizumab, trabectedin and carboplatin every 28 days, from cycles 1 to 6, then trabectedin and bevacizumab as in Arm BT. Primary endpoints were progression-free survival rate (PFS-6) and severe toxicity rate (ST-6) at 6 months, assuming a PFS-6 ≤35% for BT and ≤40% for BT+C as not of therapeutic interest and, for both arms, a ST-6 ≥ 30% as unacceptable. RESULTS: BT+C (21 patients) did not meet the safety criteria for the second stage (ST-6 45%; 95%CI: 23%-69%) but PFS-6 was 85% (95%CI: 62%-97%). BT (50 patients) had 75% PFS-6 (95%CI: 60%-87%) and 16% ST-6 (95%CI 7%-30%). CONCLUSIONS: BT compared favourably with other platinum- and non-platinum-based regimens. The combination with carboplatin needs to be assessed further in a re-modulated safer schedule to confirm its apparent strong activity. CLINICAL TRIAL REGISTRATION: NCT01735071 (Clinicaltrials.gov).

RESUMEN

INTRODUCTION: The CoQun® study is a multicenter, controlled trial aimed to evaluate the neuroprotective effects of Coqun®, an ophthalmic solution of Coenzyme q10 (CoQ10) and Vitamin E (VitE), in patients affected by primary open-angle glaucoma (POAG). Pre-clinical studies and small non-controlled clinical trials have previously shown a potential role of CoQ10 and VitE in glaucoma neuroprotection, both in vitro and in vivo. METHODS: Randomized, parallel arm, multicenter, double-blind study. POAG patients with an IOP ranging from 17 to 21 mm Hg on monotherapy with a prostaglandin analogue (PGA) will be considered for study enrollment. Inclusion criteria will be visual field (VF) mean deviation between - 4 and - 10 dB and VF Pattern Standard Deviation between 4 and 10 dB. Eligible patients will be randomized to receive CoQun® (Arm A) or placebo (Arm B), in addition to PGA monotherapy. PLANNED OUTCOMES: Primary outcome will be time to progression, defined as the time between the baseline visit and the visit with confirmed VF progression. A total of 612 patients are planned to be enrolled, to detect a hazard ratio of 0.65, with a power of 80% and an alpha error of 0.05 (two-sided). For study power calculation, 10% non-evaluable patients are assumed. This is the first study investigating, in a randomized, double-blind and controlled fashion, the neuroprotective effects of CoQ10 and VitE in POAG patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT03611530.

RESUMEN

BACKGROUND AND PURPOSE: Glioblastoma (GBM) is the most aggressive and frequent subtype of all malignant gliomas. At the time of recurrence, therapeutic options are lacking. Ortataxel, a second-generation taxane was reported to be effective in pre-clinical and phase I clinical studies. The aim of this study was to evaluate a potential therapeutic activity of ortataxel in patients with GBM recurring after surgery and first line treatment. METHODS: In this phase II study, according to a two stage design, adult patients with histologically confirmed GBM in recurrence after surgery or biopsy, standard radiotherapy and chemotherapy with temozolomide were considered eligible. Patients included were treated with ortataxel 75 mg/m2 i.v. every 3 weeks until disease progression. The primary objective of the study was to evaluate the activity of ortataxel in terms of progression free survival (PFS) at 6 months after the enrollment. PFS, overall survival at 9 months after the enrollment, objective response rate, compliance and safety were evaluated as secondary endpoints. RESULTS: Between Nov 26, 2013 and Dec 12, 2015, 40 patients were recruited across six centres. The number of patients alive and free from progression at 6 months after the enrollment, observed in the first stage was four (11.4%), out of 35 patients included in the analysis, below the minimum number of events (7 out of 33) required to continue the study with the second stage The most important toxicities were neutropenia and hepatotoxicity that occurred in 13.2% of patients and leukopenia that occurred in 15.8% of patients. CONCLUSION: Overall ortataxel treatment fail to demonstrate a significant activity in recurrent GBM patients. However in a limited number of patients the drug produced a benefit that lasted for a long time. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov, number NCT01989884.

RESUMEN

BACKGROUND AND OBJECTIVE: Opioid treatments are often prolonged because of the pathology causing pain. We focused on the cognitive functions in patients with chronic pain treated with opioids. This topic is currently controversial, but in practice, the consequences are important in patients' daily lives, social interactions, working ability, and driving. DATABASE AND DATA TREATMENT: Medline and Embase databases were searched for eligible articles. We included studies that enrolled patients with chronic noncancer pain, studies with patients receiving opioid treatment, studies with a control group not using opioids, and studies in which cognitive functions were evaluated with specific tests. The cognitive areas examined were as follows: attention, reaction time, executive functions, psychomotor speed, memory, and working memory. From 356 abstracts screened, 9 articles satisfied eligibility criteria and were included in our review: 7 observational and 7 experimental studies. We classified the pain treatments as follows: opioids, other drugs active on the central nervous system (CNS) (antidepressants/anticonvulsants), and treatments not specifically targeted to the CNS. RESULTS: Statistically significant differences were seen only with regard to attention between opioids alone and no centrally acting treatment (standardized mean difference [SMD]: -0.53, 95% confidence interval [CI] : -0.91, -0.15; P = 0.007; I2 = 23%) and between opioids combined with antidepressants and/or anticonvulsants and no centrally acting treatment (SMD: -0.62, 95% CI: -1.04, -0.20; P = 0.004; I2 = 0%). No other significant differences were observed. CONCLUSIONS: Opioids reduce attention when compared with treatments not targeted on the CNS. If opioids are used together with antidepressants and/or anticonvulsants, this effect increases. SIGNIFICANCE: These findings on the neuropsychological effects of opioids could be used to generate strategies to refine pain treatments.

RESUMEN

BACKGROUND: The evaluation of the proportional hazards (PH) assumption in survival analysis is an important issue when Hazard Ratio (HR) is chosen as summary measure. The aim is to assess the appropriateness of statistical methods based on the PH assumption in oncological trials. METHODS: We selected 58 randomised controlled trials comparing at least two pharmacological treatments with a time-to-event as primary endpoint in advanced non-small-cell lung cancer. Data from Kaplan-Meier curves were used to calculate the relative hazard at each time point and the Restricted Mean Survival Time (RMST). The PH assumption was assessed with a fixed-effect meta-regression. RESULTS: In 19% of the trials, there was evidence of non-PH. Comparison of treatments with different mechanisms of action was associated (P = 0.006) with violation of the PH assumption. In all the superiority trials where non-PH was detected, the conclusions using the RMST corresponded to that based on the Cox model, although the magnitude of the effect given by the HR was systematically greater than the one from the RMST ratio. CONCLUSION: As drugs with new mechanisms of action are being increasingly employed, particular attention should be paid on the statistical methods used to compare different types of agents.

RESUMEN

BACKGROUND: Infantile colic is typically defined as full-force crying for at least three hours per day, on at least three days per week, for at least three weeks. This condition appears to be more frequent in the first six weeks of life (prevalence range of 17% to 25%), depending on the specific location reported and definitions used, and it usually resolves by three months of age. The aetiopathogenesis of infantile colic is unclear but most likely multifactorial. A number of psychological, behavioural and biological components (food hypersensitivity, allergy or both; gut microflora and dysmotility) are thought to contribute to its manifestation. The role of diet as a component in infantile colic remains controversial. OBJECTIVES: To assess the effects of dietary modifications for reducing colic in infants less than four months of age. SEARCH METHODS: In July 2018 we searched CENTRAL, MEDLINE, Embase , 17 other databases and 2 trials registers. We also searched Google, checked and handsearched references and contacted study authors. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs evaluating the effects of dietary modifications, alone or in combination, for colicky infants younger than four months of age versus another intervention or placebo. We used specific definitions for colic, age of onset and the methods for performing the intervention. We defined 'modified diet' as any diet altered to include or exclude certain components. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Our primary outcome was duration of crying, and secondary outcomes were response to intervention, frequency of crying episodes, parental/family quality of life, infant sleep duration, parental satisfaction and adverse effects. MAIN RESULTS: We included 15 RCTs involving 1121 infants (balanced numbers of boys and girls) aged 2 to 16 weeks. All studies were small and at high risk of bias across multiple design factors (e.g. selection, attrition). The studies covered a wide range of dietary interventions, and there was limited scope for meta-analysis. Using the GRADE approach, we assessed the quality of the evidence as very low.Low-allergen maternal diet versus a diet containing known potential allergens: one study (90 infants) found that 35/47 (74%) of infants responded to a low-allergen maternal diet, compared with 16/43 (37%) of infants on a diet containing known potential allergens.Low-allergen diet or soy milk formula versus dicyclomine hydrochloride: one study (120 infants) found that 10/15 (66.6%) breastfed babies responded to dicyclomine hydrochloride, compared with 24/45 (53.3%) formula-fed babies. There was little difference in response between breastfed babies whose mother changed their diet (10/16; 62.5%) and babies who received soy milk formula (29/44; 65.9%).Hydrolysed formula versus standard formula: two studies (64 infants) found no difference in duration of crying, reported as a dichotomous outcome: risk ratio 2.03, 95% confidence interval (CI) 0.81 to 5.10; very low-quality evidence. The author of one study confirmed there were no adverse effects. One study (43 infants) reported a greater reduction in crying time postintervention with hydrolysed formula (104 min/d, 95% CI 55 to 155) than with standard formula (3 min/d, 95% CI -63 to 67).Hydrolysed formula versus another hydrolysed formula: one study (22 infants) found that two types of hydrolysed formula were equally effective in resolving symptoms for babies who commenced with standard formula (Alimentum reduced crying to 2.21 h/d (standard deviation (SD) 0.40) and Nutramigen to 2.93 h/d (SD 0.70)).Hydrolysed formula or dairy- and soy-free maternal diet versus addition of parental education or counselling: one study (21 infants) found that crying time decreased to 2.03 h/d (SD 1.03) in the hydrolysed or dairy- and soy-free group compared with 1.08 h/d (SD 0.7) in the parent education or counselling group, nine days into the intervention.Partially hydrolysed, lower lactose, whey-based formulae containing oligosaccharide versus standard formula with simethicone: one study (267 infants) found that both groups experienced a decrease in colic episodes (secondary outcome) after seven days (partially hydrolysed formula: from 5.99 episodes (SD 1.84) to 2.47 episodes (SD 1.94); standard formula: from 5.41 episodes (SD 1.88) to 3.72 episodes (SD 1.98)). After two weeks the difference between the two groups was significant (partially hydrolysed: 1.76 episodes (SD 1.60); standard formula: 3.32 episodes (SD 2.06)). The study author confirmed there were no adverse effects.Lactase enzyme supplementation versus placebo: three studies (138 infants) assessed this comparison, but none reported data amenable to analysis for any outcome. There were no adverse effects in any of the studies.Extract of Foeniculum vulgare, Matricariae recutita, and Melissa officinalis versus placebo: one study (93 infants) found that average daily crying time was lower for infants given the extract (76.9 min/d (SD 23.5), than infants given placebo (169.9 min/d (SD 23.1), at the end of the one-week study. There were no adverse effects.Soy protein-based formula versus standard cows' milk protein-based formula: one study (19 infants) reported a mean crying time of 12.7 h/week (SD 16.4) in the soy formula group versus 17.3 h/week (SD 6.9) in the standard cows' milk group, and that 5/10 (50%) responded in the soy formula group versus 0/9 (0%) in the standard cows' milk group.Soy protein formula with polysaccharide versus standard soy protein formula: one study (27 infants) assessed this comparison but did not provide disaggregated data for the number of responders in each group after treatment.No study reported on our secondary outcomes of parental or family quality of life, infant sleep duration per 24 h, or parental satisfaction. AUTHORS' CONCLUSIONS: Currently, evidence of the effectiveness of dietary modifications for the treatment of infantile colic is sparse and at significant risk of bias. The few available studies had small sample sizes, and most had serious limitations. There were insufficient studies, thus limiting the use of meta-analysis. Benefits reported for hydrolysed formulas were inconsistent.Based on available evidence, we are unable to recommend any intervention. Future studies of single interventions, using clinically significant outcome measures, and appropriate design and power are needed.

RESUMEN

PURPOSE: To investigate the efficacy and safety of a treatment strategy with latanoprost and dorzolamide in primary pediatric glaucoma patients partially responsive to surgery. PATIENTS AND METHODS: Children with primary pediatric glaucoma with postsurgical intraocular pressure (IOP) between 22 and 26 mm Hg were eligible. At baseline, patients were administered latanoprost once daily. Depending on IOP reduction, patients were allocated to continuation of latanoprost monotherapy or addition of dorzolamide twice daily, or switch to dorzolamide monotherapy 3 times daily. Patients in the dorzolamide monotherapy group with IOP reduction <20% from baseline were considered nonresponders. The primary endpoint was the percentage of responders. Study treatment continued for 3 years or until treatment failure. RESULTS: A total of 37 patients (61 eyes) were analyzed. The mean age of the patients was 4.1 years (SD: 3.8). In total, 43 eyes were included in the efficacy analysis. A total of 33 eyes (76.7%; 95% confidence interval, 61.4-88.2) were considered responders: 19 on latanoprost monotherapy, 11 on the latanoprost/dorzolamide combination, and only 3 on the dorzolamide monotherapy. The efficacy of pharmacological treatment was inversely related to central corneal thickness at the time of surgery and the age at the time of surgery. IOP reduction was 9.7 mm Hg (SD: 2.6) for latanoprost, 8.4 mm Hg (SD: 1.5) for the latanoprost/dorzolamide combination, and 9.3 mm Hg (SD: 2.5) for the dorzolamide monotherapy. None of the patients was withdrawn because of adverse events. CONCLUSIONS: Latanoprost alone or in combination with dorzolamide is safe and highly effective in lowering IOP in children after surgery. Nonresponders were mainly patients with early presentation of the disease.

RESUMEN

BACKGROUND: Patients with recurrent/metastatic uterine leiomyosarcoma (U-LMS) have a dismal prognosis. This phase II study aims to evaluate trabectedin efficacy and safety in advanced U-LMS. METHODS: Eligible patients had received ≥ one line of chemotherapy. Gemcitabine ± docetaxel naive patients were randomised to Arm A: trabectedin 1.3 mg/m2 or calibration Arm B: gemcitabine 900 mg/m2 and docetaxel 75 mg/m2. Patients who had already received gemcitabine ± docetaxel directly entered Arm A. Primary end-point: 6-month progression-free rate (PFS-6). The null hypothesis that the true PFS-6 = 14% was tested against a one-sided alternative. This design yielded a 5% type I error rate and 90% power when the true PFS-6 is 25%. RESULTS: Overall, 126 patients entered Arm A (45 from randomisation and 81 directly) and 42 Arm B. Arm A patients characteristics: median age = 57; ≥2 previous chemotherapy lines = 37.4%; metastatic disease = 93%. The study met the condition for trabectedin activity: PFS-6 = 35.2% (95% CI: 26.2-45). No difference in PFS by the number of previous chemotherapy lines emerged. Median OS = 20.6 months (IQR: 8-36.4). In Arm B, the PFS-6 = 51.5% (95% CI: 33.5-69.2). No toxic deaths occurred. In Arm A, only 4 patients interrupted treatment for toxicity. CONCLUSIONS: Trabectedin is active and well tolerated, retaining similar efficacy across one to three previous lines of chemotherapy.

RESUMEN

BACKGROUND: The prognosis of early breast cancer (EBC) depends on patient and tumor characteristics. The association between tumor size, the largest diameter in TNM staging, and prognosis is well recognized. According to TNM, tumors classified as T2, could have very different volumes; e.g. a tumor of 2.1 cm has a volume of 4500 mm3, while a tumor of 4.9 cm has a volume of 60.000 mm3 even belonging to the same class. The aim of the study is to establish if the prognostic role of tumor size, expressed as diameter and volume, has been overshadowed by other factors. METHODS: The primary objective is to evaluate the association between tumor dimensions and overall survival (OS) / disease free survival (DFS), in our institution from January 1st 2005 to September 30th 2013 in a surgical T1-T2 population. Volume was evaluated with the measurement of three half-diameters of the tumor (a, b and c), and calculated using the following formula: 4/3π x a x b x c. RESULTS: 341 patients with T1-T2 EBC were included. 86.5% were treated with conservative surgery. 85.1% had a Luminal subtype, 9.1% were Triple negative and 7.4% were HER2 positive. Median volume was 942 mm3 (range 0.52-31.651.2). 44 patients (12.9%) relapsed and 23 patients died. With a median follow-up of 6.5 years, the univariate analysis for DFS showed an association between age, tumor size, volume, histological grading and molecular subtype. The multivariate analysis confirmed the statistically significant association only for molecular subtype (p 0.005), with a worse prognosis for Triple negative and HER2 positive subtypes compared with Luminal (HR: 2.65; 95%CI: 1.34-5.22). Likewise for OS, an association was shown by the multivariate analysis solely for molecular subtype (HER2 and Triple negative vs. Luminal. HR: 2.83; 95% CI:1.46-5.49; p 0.002). CONCLUSIONS: In our study, the only parameter that strongly influences survival is molecular subtype. These findings encourage clinicians to choose adjuvant treatment not based on dimensional criteria but on biological features.

RESUMEN

PURPOSE: To investigate the efficacy and safety of a treatment strategy with latanoprost and dorzolamide in primary pediatric glaucoma patients partially responsive to surgery. PATIENTS AND METHODS: Children with primary pediatric glaucoma having postsurgical untreated intraocular pressure (IOP) between 22 and 26 mm Hg were eligible. At baseline, patients were administered latanoprost once daily. Depending on IOP reduction, patients were allocated to continuation of latanoprost monotherapy or addition of dorzolamide twice daily, or switch to dorzolamide monotherapy 3 times daily. Patients in the dorzolamide monotherapy group with IOP reduction <20% from baseline were considered nonresponders. The primary endpoint was the percentage of responders. Study treatment continued for 3 years or until treatment failure. The present article reports the 1-year analysis results. RESULTS: A total of 35 patients (57 eyes) were analyzed. The mean age was 4.0 years (SD, 3.8). In total, 51 eyes were included in the efficacy analysis. In total, 43 eyes (84.3%; 95% confidence interval, 74.3-94.3) were considered responders: 29 on latanoprost monotherapy, 11 on the latanoprost/dorzolamide combination, and only 3 on the dorzolamide monotherapy. The efficacy of pharmacological treatment was inversely related to the age at the time of surgery. IOP reduction was 8.7 mm Hg (SD, 2.2) for latanoprost, 7.5 mm Hg (SD, 1.4) for the latanoprost/dorzolamide combination, and 8.7 mm Hg (SD, 2.1) for the dorzolamide monotherapy. Only mild or moderate local adverse events were noted. None of the patients was withdrawn due to adverse events. CONCLUSION: Latanoprost alone or in combination with dorzolamide is safe and highly effective in lowering IOP in children postsurgery. Nonresponders were mainly patients with early presentation of the disease.

RESUMEN

The platinum-free interval is the most important predictive factor of a response to subsequent lines of chemotherapy and the most important prognostic factor for progression-free and overall survival in patients with recurrent epithelial ovarian cancer. A nonplatinum regimen is generally considered the most appropriate approach when the disease recurs very early after the end of chemotherapy, whereas platinum-based chemotherapy is usually adopted when the platinum-free interval exceeds 12 months. However, the therapeutic management of patients with intermediate sensitivity (ie, when the relapse occurs between 6 and 12 months) remains debatable. Preclinical and clinical data suggest that the extension of platinum-free interval (using a nonplatinum-based regimen) might restore platinum sensitivity, thus allowing survival improvement. The objective of this review was to critically analyze preclinical and clinical evidences supporting this hypothesis. Cancer 2017;123:3450-9. © 2017 American Cancer Society.

RESUMEN

BACKGROUND: Radiosurgery(RS), both in single and multiple sessions, have been performed for intracranial meningiomas. Different aspects are still controversial on this field. The aim of this systematic review is to summarize the current literature on long-term efficacy and safety of RS for meningiomas. METHODS: Online databases were searched for studies published until April 2015. The primary outcomes were disease control and progression-free-survival(PFS). The secondary outcomes were symptom control and radiation-induced toxicity. RESULTS: The estimate of disease control rate ranged from 87.0% to 100.0% at 5 years and from 67.0% to 100.0% at 10 years. The PFS rate ranged 78.0%-98.9% and 53.1%-97.2% at 5 and 10 years, respectively. The overall symptom control was 92.3%, the overall toxicity was 8.1%. CONCLUSIONS: RS can be considered a safe and effective treatment. Efforts are needed in standardizing the definition of local and symptom control and toxicity in order to properly compare different treatment schedules.

RESUMEN

BACKGROUND: Infantile colic is a common disorder in the first months of life, affecting somewhere between 4% and 28% of infants worldwide, depending on geography and definitions used. Although it is self limiting and resolves by four months of age, colic is perceived by parents as a problem that requires action. Pain-relieving agents, such as drugs, sugars and herbal remedies, have been suggested as interventions to reduce crying episodes and severity of symptoms. OBJECTIVES: To assess the effectiveness and safety of pain-relieving agents for reducing colic in infants younger than four months of age. SEARCH METHODS: We searched the following databases in March 2015 and again in May 2016: CENTRAL, Ovid MEDLINE, Embase and PsycINFO, along with 11 other databases. We also searched two trial registers, four thesis repositories and the reference lists of relevant studies to identify unpublished and ongoing studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs evaluating the effects of pain-relieving agents given to infants with colic. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures of The Cochrane Collaboration. MAIN RESULTS: We included 18 RCTs involving 1014 infants. All studies were small and at high risk of bias, often presenting major shortcomings across multiple design factors (e.g. selection, performance, attrition, lack of washout period).Three studies compared simethicone with placebo, and one with Mentha piperita; four studies compared herbal agents with placebo; two compared sucrose or glucose with placebo; five compared dicyclomine with placebo; and two compared cimetropium - one against placebo and the other at two different dosages. One multiple-arm study compared sucrose and herbal tea versus no treatment. Simethicone. Comparison with placebo revealed no difference in daily hours of crying reported for simethicone at the end of treatment in one small, low-quality study involving 27 infants. A meta-analysis of data from two cross-over studies comparing simethicone with placebo showed no difference in the number of of infants who responded positively to treatment (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.73 to 1.23; 110 infants, low-quality evidence).One small study (30 participants) compared simethicone with Mentha piperita and found no difference in crying duration, number of crying episodes or number of responders. Herbal agents. We found low-quality evidence suggesting that herbal agents reduce the duration of crying compared with placebo (mean difference (MD) 1.33, 95% CI 0.71 to 1.96; three studies, 279 infants), with different magnitude of benefit noted across studies (I² = 96%). We found moderate-quality evidence indicating that herbal agents increase response over placebo (RR 2.05, 95% CI 1.56 to 2.70; three studies, 277 infants). Sucrose. One very low-quality study involving 35 infants reported that sucrose reduced hours spent crying compared with placebo (MD 1.72, 95% CI 1.38 to 2.06). Dicyclomine. We could consider only one of the five studies of dicyclomine (48 infants) for the primary comparison. In this study, more of the infants given dicyclomine responded than than those given placebo (RR 2.50, 95% CI 1.17 to 5.34). Cimetropium bromide. Data from one very low-quality study comparing cimetropium bromide with placebo showed reduced crying duration among infants treated with cimetropium bromide (MD -30.20 minutes per crisis, 95% CI -39.51 to -20.89; 86 infants). The same study reported that cimetropium increased the number of responders (RR 2.29, 95% CI 1.44 to 3.64).No serious adverse events were reported for all of the agents considered, with the exception of dicyclomine, for which two of five studies reported relevant adverse effects (longer sleep 4%, wide-eyed state 4%, drowsiness 13%). AUTHORS' CONCLUSIONS: At the present time, evidence of the effectiveness of pain-relieving agents for the treatment of infantile colic is sparse and prone to bias. The few available studies included small sample sizes, and most had serious limitations. Benefits, when reported, were inconsistent.We found no evidence to support the use of simethicone as a pain-relieving agent for infantile colic.Available evidence shows that herbal agents, sugar, dicyclomine and cimetropium bromide cannot be recommended for infants with colic.Investigators must conduct RCTs using standardised measures that allow comparisons among pain-relieving agents and pooling of results across studies. Parents, who most often provide the intervention and assess the outcome, should always be blinded.
