This study depicts a comparative carbon footprint analysis of two tertiary wastewater treatment methods: chlorination and photocatalytic. It integrates data from an extensive literature review and an on-site investigation conducted at the Aqualia plant in Spain. The analysis employed a Life Cycle Assessment (LCA) methodology using SimaPro software to assess the carbon footprint of each treatment method. Data was collected from various literature sources and the Aqualia plant. Results indicate that the chlorination process exhibits a lower carbon footprint than the photocatalytic process. Notably, the electricity requirements of the photocatalytic treatment contribute significantly to its higher carbon emissions. The literature review and the data collected from the Aqualia plant consistently support the finding that the energy-intensive nature of the photocatalytic process leads to more significant carbon emissions. Despite the higher treatment efficiency of the photocatalytic process, the analysis reveals that the chlorination process remains a more environmentally favorable choice regarding carbon footprint. The substantial electricity demand of the photocatalytic process offsets its efficiency benefits, resulting in higher carbon emissions. In conclusion, while photocatalytic treatment demonstrates superior wastewater treatment efficiency, a holistic consideration of environmental impacts is crucial. These insights provide valuable guidance for stakeholders in the wastewater treatment industry, supporting adopting sustainable practices that prioritize reducing carbon emissions.

El Síndrome de Moebius (MBS) es una enfermedad rara, caracterizada principalmente por parálisis facial y frecuentemente acompañada de alteraciones oculares asociadas al compromiso del VI nervio craneal. Además es frecuente encontrar anomalías orofaciales y de miembros en estos pacientes. En este artículo se presenta un paciente masculino de nueve meses con el cuadro clínico de Síndrome de Moebius en el cual se discuten los aspectos genéticos y medioambientales asociados a esta patología. Desde la introducción del misoprostol y su uso inadecuado como agente abortivo, se ha observado un incremento en la frecuencia de recién nacidos con Síndrome de Moebius asociados al uso de este medicamento. Al día de hoy, tanto el factor genético como el factor medioambiental se encuentran asociados al Síndrome de Moebius. Finalmente, es importante alertar a la comunidad médica y a la población en general acerca del riesgo teratogénico del misoprostol y de la importancia del consejo genético cuando nace un paciente con Síndrome de Moebius.

Background: The randomized, open-label, phase III LYNK-003 study assessed the efficacy of first-line maintenance olaparib, alone or in combination with bevacizumab, versus bevacizumab plus a fluoropyrimidine in participants with unresectable or metastatic colorectal cancer (mCRC). We present results of the prespecified interim futility analysis., Methods: Eligible participants were ≥18 years of age with unresectable or mCRC that had not progressed after induction with first-line bevacizumab plus 5-fluorouracil plus oxaliplatin plus leucovorin (FOLFOX) or capecitabine plus oxaliplatin (CAPOX). Participants were randomly assigned 1:1:1 to olaparib plus bevacizumab, olaparib alone, or bevacizumab plus a fluoropyrimidine (5-fluorouracil or capecitabine). The primary end point was progression-free survival (PFS) per RECIST v1.1 by central review., Results: Between August 2020 and May 2022, 309 participants were assigned to olaparib plus bevacizumab (n = 104), olaparib (n = 107), or bevacizumab plus fluoropyrimidine (n = 98). At interim analysis, with a median follow-up of 7.6 months (range 0.1-19.7 months), the median PFS was 3.7 months (95% CI 2.8-5.3) with olaparib plus bevacizumab (HR 1.52; 95% CI 1.02-2.27; P = 0.982) and 3.5 months (95% CI 2.0-3.7) with olaparib (HR 2.11; 95% CI 1.39-3.18; P = 0.999) versus 5.6 months (95% CI 3.8-5.9) with bevacizumab plus fluoropyrimidine. Treatment-related adverse events occurred in 64 (62%), 52 (50%), and 57 (59%) participants, respectively. There were no treatment-related deaths., Conclusion: The LYNK-003 study was stopped prematurely as criteria for futility were met. Maintenance olaparib with or without bevacizumab did not demonstrate clinical efficacy compared with bevacizumab plus a fluoropyrimidine., Gov Registration: NCT04456699., Competing Interests: Declaration of Competing Interest Atsuo Takashima reports grants and payment or honoraria from Lilly, Ono Pharmaceutical, Taiho Pharmaceutical, Chugai Pharma, Takeda, and Merck Serono.

Background: In Colombia and worldwide, breast cancer (BC) is the most frequently diagnosed neoplasia and the leading cause of death from cancer among women. Studies predominantly involve hereditary and familial cases, demonstrating a gap in the literature regarding the identification of germline mutations in unselected patients from Latin-America. Identification of pathogenic/likely pathogenic (P/LP) variants is important for shaping national genetic analysis policies, genetic counseling, and early detection strategies. The present study included 400 women with unselected breast cancer (BC), in whom we analyzed ten genes, using Whole Exome Sequencing (WES), know to confer risk for BC, with the aim of determining the genomic profile of previously unreported P/LP variants in the affected population. Additionally, Multiplex Ligation-dependent Probe Amplification (MLPA) was performed to identify Large Genomic Rearrangements (LGRs) in the BRCA1/2 genes. To ascertain the functional impact of a recurrent intronic variant (ATM c.5496 + 2_5496 + 5delTAAG), a minigene assay was conducted., Results: We ascertained the frequency of P/LP germline variants in BRCA2 (2.5%), ATM (1.25%), BRCA1 (0.75%), PALB2 (0.50%), CHEK2 (0.50%), BARD1 (0.25%), and RAD51D (0.25%) genes in the population of study. P/LP variants account for 6% of the total population analyzed. No LGRs were detected in our study. We identified 1.75% of recurrent variants in BRCA2 and ATM genes. One of them corresponds to the ATM c.5496 + 2_5496 + 5delTAAG. Functional validation of this variant demonstrated a splicing alteration probably modifying the Pincer domain and subsequent protein structure., Conclusion: This study described for the first time the genomic profile of ten risk genes in Colombian women with unselected BC. Our findings underscore the significance of population-based research, advocating the consideration of molecular testing in all women with cancer., (© 2024. The Author(s).)

Introduction and objective: The approach to patients with advanced or metastatic high-grade epithelial ovarian cancer (EOC) has evolved over time with the advent of new therapies and multimodal strategies. The objective of this consensus of experts is to generate national recommendations for the profiling and management of advanced or metastatic high-grade OEC, defined as stages III and IV of the “The International Federation of Gynecology and Obstetrics (FIGO) classification at the time of diagnosis to base on the literature review that included international evidence-based clinical practice guidelines (CPG). Material and methods: Eleven panelists (oncologists and gynecological oncologists) answered 8 questions about the profiling and management of advanced or metastatic ovarian epithelial carcinoma. The panelists were chosen for their academic profile and influence in national health institutions. Guidelines from the “ESMO Standardized Operating Procedures Consensus Conference” were used to develop the consensus. It was agreed that the level of agreement to accept a recommendation should be ≥ 80%. The document was peer reviewed. Results: Eight general recommendations are made, which are presented into five domains. Some of these recommendations are subdivided into specific recommendations. Initial treatment Recommendation 1.1 Complete primary cytoreduction (PCS) surgery is suggested as the initial therapy of choice for patients with high-grade or metastatic EOC, which should ideally be carried out in centers with experience, followed by adjuvant therapy. 1.2 Neoadjuvant chemotherapy followed by interval cytoreduction surgery (ICS) is suggested in those who are unlikely to achieve a complete cytoreduction in PCS either due to unresectable metastatic disease or who present unresectability criteria (imaging, laparoscopic and/or by laparotomy) and that have been defined by a gynecological oncologist and patients with poor functional status and comorbidities according to the criteria of the multidisciplinary team (clinical oncology, gynecological oncology, radiology, etc.). Recommendation 2. In patients with high-grade epithelial ovarian cancer (EOC), in stage III locally advanced or metastatic, who received neoadjuvant chemotherapy and achieved a complete or partial response (cytoreduction with tumor residue < 2.5 mm), the use of Hyperthermic IntraPeritoneal Chemotherapy (HIPEC) could be considered as an alternative to standard platinum-based adjuvant intravenous chemotherapy during interval cytoreductive surgery, after discussion in a multidisciplinary tumor board, at a center experienced in treating this type of patients. Use of genetic testing. Recommendation 3. It is suggested at the time of diagnosis to offer molecular genetic testing to all patients with high-grade advanced or metastatic EOC regardless of family history. Recommendation 4. It is suggested to offer genetic counseling, by qualified personnel, to all patients with high-grade advanced or metastatic EOC who are ordered genetic testing. Recommendation 5. It is suggested that all patients with advanced or metastatic high-grade EOC undergo a germ panel that includes the Breast Cancer Susceptibility Genes 1/2 genes (BRCA 1/2) and the other susceptibility genes according to with institutional protocols and the availability of genetic testing panels; If it is negative, then somatic testing should be performed that includes the homologous recombination deficiency (HRD) status, regardless of family history. Adjuvant Therapy Recommendation 6. 6.1. It is suggested that all patients with advanced stage III/IV EOC, with PSC of (0-2), got adjuvant intravenous chemotherapy as standard treatment within six weeks after Prc. It is suggested paclitaxel/carboplatin. Recommendation 6.2. It is suggested to use standard chemotherapy base on platinum plus Bevacizumab as adjuvant chemotherapy to patients with high-risk disease (EOC stage IV or stage III with suboptimal tumor cytoreduction), following by bevacizumab as maintenance. The use of bevacizumab as maintenance therapy is not recommended if bevacizumab was not included in the first line of treatment. We suggested the dose used in GOG-0218 and ICON7 trials. Recommendation 6.3 It is suggested combined intravenous/intraperitoneal chemotherapy only for selected patients, with optimal cytoreduction (residual lesions < 1 cm), especially those without residual disease (R0) and who are evaluated in a multidisciplinary meeting. It is not considered standard treatment. Recommendation 6.4. 6.4.1 It is suggested to use Poly ADP ribose polymerase (PARP) inhibitors such as olaparib or niraparib as maintenance after receiving first-line chemotherapy in patients with stage III/IV BRCA1/2 positive EOC who received platinumbased chemotherapy and obtained complete response/partial response (CR/PR), 6.4.2 It is suggested to use olaparib alone or in combination with bevacizumab or niraparib in patients with stage III/IV BRCA1/2 positive EOC who received platinum-based chemotherapy plus bevacizumab and achieved CR/PR. 6.4.3 It is suggested to use niraparibin patients with stage III/IV BRCA1/2 negative or unknown EOC who received platinum-based chemotherapy and achieved CR/PR. 6.4.4 It is suggested to use bevacizumab or olaparib plus bevacizumab in patients with EOC stage III/IV BRCA1/2 negative or unknown (HRD positive) who received platinum-based chemotherapy plus bevacizumab and obtained CR/PR. Treatment of disease relapse Recommendation 7. Secondary cytoreductive surgery followed by chemotherapy is suggested for selected patients with high-grade advanced EOC in first relapse, platinum-sensitive (platinum-free interval ≥ 6 months), positive “Arbeitsgemeinschaft Gynäkologische Onkologie – AGO” score or “I-model” positive (< 4.7) with a potential resection to R0 in centers with access to optimal surgical and postoperative support. Note: Platinum-free interval and AGO score have only been developed as positive predictors of complete resection and not to exclude patients from surgery. Recommendation 8. 8.1 For patients with relapse advanced high-grade EOC platinum-sensitive, the following is suggested: Platinum-based combination chemotherapy: carboplatin/liposomal doxorubicin or carboplatin/paclitaxel or carboplatin/nab-paclitaxel or carboplatin/docetaxel or carboplatin/gemcitabine) for six cycles. If combination therapy is not tolerated, give carboplatin or cisplatin alone. Combination chemotherapy (carboplatin/gemcitabine or carboplatin/paclitaxel or carboplatin/doxorubicin liposomal) plus bevacizumab followed by bevacizumab as maintenance (until progression or toxicity). Recommendation 8.2 For patients with relapsed advanced high-grade EOC platinum-resistant, it is suggested: Sequential treatment with chemotherapy, preferably with a non-platinum single agent (weekly paclitaxel or pegylated liposomal doxorubicin or docetaxel or oral etoposide or gemcitabine or trabectidine or, topotecan). Weekly paclitaxel or pegylated liposomal doxorubicin or topotecan could be administrate with or without bevacizumab. Other agents are considered potentially active (capecitabine, cyclophosphamide, ifosfamide, irinotecan, oxaliplatin, pemetrexed, vinorelbine, cyclophosphamide) could be recommended for later lines. Hormone receptor-positive patients who do not tolerate or have no response to cytotoxic regimens may receive hormone therapy with tamoxifen or other agents, including aromatase inhibitors (anastrozole and letrozole) or leuprolide acetate, or megestrol acetate. Patients with a performance score ≥ 3 should be considered only for best supportive care. Recommendation 8.3 Maintenance therapy with PARP inhibitors: It is suggested in patients with relapse advanced high-grade EOC stage III/IV BRCA1/2 (positive, negative or unknown) who have received two or more lines of platinum-based chemotherapy and have achieved CR/PR, use olaparib, niraparib or rucaparib. Niraparib could be useful in BRCA 1/2 +/-/unknown patients, as rucaparib, however, the latter does not yet have approval from the regulatory office in Colombia. Conclusions: It is expected that the recommendations issued in this consensus will contribute to improving clinical care, oncological impact, and quality of life of these women.

Background: There is an ongoing debate as to whether sex could be associated with immune checkpoint inhibitor (ICI) benefit. Existing literature data reveal contradictory results, and data on first-line immune combinations are lacking., Method: This was a real-world, multicenter, international, observational study to determine the sex effects on the clinical outcomes in metastatic renal cell carcinoma (mRCC) patients treated with immuno-oncology combinations as first-line therapy., Results: A total of 1827 mRCC patients from 71 cancer centers in 21 countries were included. The median OS was 38.7 months (95% CI 32.7-44.2) in the overall study population: 40.0 months (95% CI 32.7-51.6) in males and 38.7 months (95% CI 26.4-41.0) in females (p = 0.202). The median OS was higher in males vs. females in patients aged 18-49y (36.9 months, 95% CI 29.0-51.6, vs. 24.8 months, 95% CI 16.8-40.4, p = 0.426, with + 19% of 2y-OS rate, 72% vs. 53%, p = 0.006), in the clear cell histology subgroup (44.2 months, 95% CI 35.8-55.7, vs. 38.7 months, 95% CI 26.0-41.0, p = 0.047), and in patients with sarcomatoid differentiation (34.4 months, 95% CI 26.4-59.0, vs. 15.3 months, 95% CI 8.9-41.0, p < 0.001). Sex female was an independent negative prognostic factor in the sarcomatoid population (HR 1.72, 95% CI 1.15 - 2.57, p = 0.008)., Conclusions: Although the female's innate and adaptive immunity has been observed to be more active than the male's, women in the subgroup of clear cell histology, sarcomatoid differentiation, and those under 50 years of age showed shorter OS than males., (© 2024.

Purpose: The prevalence of homologous recombination repair gene mutations (HRRm) in patients with metastatic castration-resistant prostate cancer (mCRPC) in Latin America and the Caribbean (LAC) is unknown. Prevalence of homologous Recombination repair (HRR) gene mutatiOns in patientS with metastatic castration resistant ProstatE Cancer in LaTin America (PROSPECT) aimed to determine this prevalence and to describe the demographic and clinical characteristics of the participants., Materials and Methods: This was a prospective, cross-sectional, multicenter study across 11 cancer centers in seven LAC countries. After informed consent, all eligible participants underwent genomic testing by provided blood samples for germline HRR testing; they also provided PC tissue blocks if available for somatic HRR testing., Results: Between April 2021 and April 2022, 387 patients (median age, 70 years [49-89], 94.3% Eastern Cooperative Oncology Group 0-1) with mCRPC were enrolled in the study. Almost 40% of them had a family history of cancer, and the overall time from their initial PC and mCRPC diagnosis was 3 years and 1 year, respectively. The overall prevalence of germline HRRm was 4.2%. The mutations detected included the genes CHEK2 (n = 4, 1%), ATM (n = 3, 0.8%), BRCA2 (n = 3, 0.8%), BRIP1 (n = 2, 0.5%), RAD51B (n = 2, 0.5%), BRCA1 (n = 1, 0.3%), and MRE11 (n = 1, 0.3%). The prevalence of somatic HRRm could not be assessed because of high HRR testing failure rates (79%, 199/251) associated with insufficient DNA, absence of tumor cells, and poor-quality DNA., Conclusion: Despite the study's limitations, to our knowledge, PROSPECT was the first attempt to describe the prevalence of HRRm in patients with PC from LAC. Notably, the germline HRRm prevalence in this study was inferior to that observed in North American and European populations. The somatic HRR testing barriers identified are being addressed by several projects to improve access to HRR testing and biomarker-based therapies in LAC.

Urothelial carcinoma (UC) is the 10 th most common cancer globally with an almost 4 times higher prevalence in men. The main risk factors for development of urothelial carcinoma are advanced age, smoking, arsenic contamination, exposure to carcinogens. Metastatic urothelial carcinoma (mUC) has overall poor prognosis with a 5-year overall survival rate of only < 5%. The standard of care comprises of platinum-based chemotherapy, but the responses are often not sustained. A working group was established with an objective to discuss the most recent clinical data on the genitourinary tumors of interest and comprised of experts across Latin America, Emerging Asia (except China, Japan, and South Korea), Africa, and the Middle East (known as Emerging Markets or EM). There is an evident disparity in terms of uneven mortality and incidence rate distribution among various regions. There is a lack and/or insufficient data on epidemiology, treatment, and outcomes in the EM. The lack of registries impacts the healthcare decisions and the lower incidence from the region might not be reflective of the true disease burden. The treatment outcomes of mUC can be improved by understanding the current disease burden and treatment approach of mUC and identifying the gaps and challenges associated with management. Hence, a literature review was developed to summarize the current disease burden and treatment approach of mUC across EM. The review also highlights the unmet needs for mUC management in EM and suggests a way forward to improve the current situation in order to better serve the patients., Competing Interests: Disclosure All authors are members of the Emerging Markets Genitourinary Cancer Working Group.

Background: Concomitant medications may potentially affect the outcome of cancer patients. In this sub-analysis of the ARON-2 real-world study (NCT05290038), we aimed to assess the impact of concomitant use of proton pump inhibitors (PPI), statins, or metformin on outcome of patients with metastatic urothelial cancer (mUC) receiving second-line pembrolizumab., Methods: We collected data from the hospital medical records of patients with mUC treated with pembrolizumab as second-line therapy at 87 institutions from 22 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall response rate. We carried out a survival analysis by a Cox regression model., Results: A total of 802 patients were eligible for this retrospective study; the median follow-up time was 15.3 months. PPI users compared to non-users showed inferior PFS (4.5 vs. 7.2 months, p = 0.002) and OS (8.7 vs. 14.1 months, p < 0.001). Concomitant PPI use remained a significant predictor of PFS and OS after multivariate Cox analysis. The use of statins or metformin was not associated with response or survival., Conclusions: Our study results suggest a significant prognostic impact of concomitant PPI use in mUC patients receiving pembrolizumab in the real-world context. The mechanism of this interaction warrants further elucidation., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Introduction: During the pandemic, it has been recommended that vaccination against COVID-19 be a priority for patients with cancer; however, these patients were not included in the initial studies evaluating the available vaccines. Objective: To define the impact of vaccination against COVID-19 in preventing the risk of complications associated with the infection in a cohort of patients with cancer in Colombia. Methods: An analytical observational cohort study, based on national registry of patients with cancer and COVID 19 infection ACHOC-C19, was done. The data was collected from June 2021, until October 2021. Inclusion criteria were: Patients older than 18 years with cancer diagnosis and confirmed COVID-19 infection. Data from the unvaccinated and vaccinated cohorts were compared. Outcomes evaluated included all-cause mortality within 30 days of COVID-19 diagnosis, hospitalization, and need for mechanical ventilation. The estimation of the effect was made through the relative risk (RR), the absolute risk reduction (ARR) and the number needed to treat (NNT). Multivariate analysis was performed using generalized linear models. Results : 896 patients were included, of whom 470 were older than 60 years (52.4%) and 59% were women (n=530). 172 patients were recruited in the vaccinated cohort and 724 in the non-vaccinated cohort (ratio: 1 to 4.2). The cumulative incidence of clinical outcomes among the unvaccinated vs vaccinated patients were: for hospitalization 42% (95% CI: 38.7%-46.1%) vs 29%; (95% CI: 22.4%-36.5%); for invasive mechanical ventilation requirement 8.4% (n=61) vs 4.6% (n=8) and for mortality from all causes 17% (n=123) vs 4.65% (n=8). Conclusion: In our population, unvaccinated patients with cancer have an increased risk of complications for COVID -19 infection, as hospitalization, mechanical ventilation, and mortality. It is highly recommended to actively promote the vaccination among this population., Competing Interests: Competing Interests: The authors have declared that no competing interest exists., (© The author(s).)

Nivolumab is a human programmed death receptor-1 blocking antibody, used as treatment option in patients with advanced non-small-cell lung cancer (NSCLC). We assessed the nivolumab efficacy in terms of survival and response to treatment as second-line (2L) or third-line (3L) therapy in patients with advanced NSCLC. This is a multicentric observational study. Data of patients with advanced NSCLC who received nivolumab as 2L or 3L treatment were analyzed retrospectively. Information regarding patient demographics and clinical backgrounds, treatment patterns from diagnosis to post-nivolumab treatment, effectiveness, and safety of nivolumab treatment were collected. The outcomes evaluated were overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) to treatment. OS and PFS were estimated with the Kaplan-Meier method and the differences were evaluated through the log-rank test. Data of 178 patients were included. The median follow-up was 26.8 months (interquartile range (IQR): 20.3-40.4). Nivolumab was commonly used as a 2L treatment (77.5%). The outcomes in this setting (2L) were as follows: ORR was 21.0%, and the median PFS and OS were 5.5 months (95% confidence interval (CI): 4.5-6.5) and 12.4 months (95% CI: 10.8-14.0), respectively. In 3L, the ORR with nivolumab was 15.0%, the median PFS and OS were 4.1 months (95% CI: 3.1-5.1) and 10.1 months (95% CI: 9.4-10.6), respectively. Three patients (1.7%) required discontinuation due to toxicity. Nivolumab effectiveness and safety in this scenario was consistent with that reported by previous trials and other real-world data.

Background: Immune checkpoint inhibitor-based combination therapy (ICI-based combination) is a new standard of care for metastatic clear cell renal cell carcinoma (mRCC) in the frontline setting. Patients with poor performance status (PS) (≥2) were excluded from pivotal trials. Hence, the activity and safety of ICI-based combination therapy in this group of patients is still unknown., Methods: We performed a multicentre retrospective study of PS ≥2 mRCC patients who received frontline ICI-based combination, either nivolumab-ipilimumab (NI) or pembrolizumab-axitinib (AP). Patients' characteristics, clinical outcomes, and toxicity were collected. We analysed overall response rate (ORR), median progression-free survival (mPFS), median overall survival (mOS) and grade ≥3 adverse events (G ≥ 3AEs). The association between the predictive biomarker IPI (immune prognostic index) and ORR/PFS/OS was also evaluated., Results: We identified 70 mRCC patients with PS ≥2 treated with ICI-based combination across 14 institutions between October 2017 and December 2021, including 45 and 25 patients were treated with NI and AP, respectively. Median age at diagnosis was 63 years, 51 (73%) were male, only 17 (24%) had prior nephrectomy, 50 (71%) had synchronous metastatic disease at diagnosis, and 16 (23%) had brain metastases. Sixty-one (87%) and 9 (13%) patients had ECOG (Eastern Cooperative Oncology Group) PS 2 and 3, respectively, and 25 (36%) and 45 (64%) patients were intermediate and poor International Metastatic RCC Database Consortium (IMDC) risk, respectively. Among all, 91% were clear cell RCC, 7 patients had sarcomatoid features. At the time of the analysis (median follow-up 11.1 months), 41% patients were dead. Median PFS and mOS in the entire cohort were 5.4 months and 16.0 months, respectively; ORR was 31%. No significant differences in ORR, PFS, OS, or G ≥3AEs were seen between NI and AP. The intermediate and poor IPI groups were significantly associated with reduced ORR and shorter PFS., Conclusion: We report the first cohort of PS ≥2 mRCC patients treated with frontline ICI-based combination therapy. The survival outcomes in our cohort were inferior to that reported in pivotal trials. No significant differences in ORR, PFS, OS or toxicity were seen between NI and AP. Prospective real-world studies are needed to confirm these results., Competing Interests: Conflict of interest statement LCA: BMS Belgium Travel, Accommodation and Expenses.

Parkinson's Disease (PD) is a multifactorial neurodegenerative disease characterized by motor and non-motor symptoms. The etiology of PD remains unclear. However, several studies have demonstrated the interplay of genetic, epigenetic, and environmental factors in PD. Early-onset PD (EOPD) is a subgroup of PD diagnosed between the ages of 21 and 50. Population genetic studies have demonstrated great genetic variability amongst EOPD patients. Hence, this study aimed to obtain a genetic landscape of EOPD in the Cypriot population. Greek-Cypriot EOPD patients ( n = 48) were screened for variants in the six most common EOPD-associated genes ( PINK1 , PRKN , FBXO7 , SNCA , PLA2G6 , and DJ-1 ). This included DNA sequencing and Multiplex ligation-dependent probe amplification (MLPA). One previously described frameshift variant in PINK1 (NM&#95;032409.3:c.889del) was detected in five patients (10.4%)-the largest number to be detected to date. Copy number variations in the PRKN gene were identified in one homozygous and 3 compound heterozygous patients (8.3%). To date, the pathogenic variants identified in this study have explained the PD phenotype for 18.8% of the EOPD cases. The results of this study may contribute to the genetic screening of EOPD in Cyprus.

Opinion Statement: Neuroendocrine tumors (NET) represent a complex and heterogeneous group of malignancies arising from the diffuse endocrine cells and other cells derived from the neural crest. Advanced disease is observed at diagnosis in more than one-third of patients. Somatostatin analogs (SSA) are the cornerstone in advanced well-differentiated NET treatment. Unfortunately, most patients will eventually develop resistance to SSA treatment by different mechanisms that are not fully understood. In some cases of refractory carcinoid syndrome or progressive disease, the increase of SSA dose may help to reach out a symptomatic and/or tumor growth control. The clinical evidence behind above-label SSA administration is limited and should be individualized and discussed patient by patient. Some questions regarding high-dose SSA use are unsolved, such as the optimal dose to use, the frequency of administration, or the need of deepen molecular understanding that could help to adequately select patients for this approach., (© 2022.

Background: Novel combination therapies have been shown to improve the outcomes of treatment-naive patients with locally advanced or metastatic renal cell carcinoma (aRCC). However, the optimal systemic therapy for aRCC of favorable risk has yet to be clarified. We aimed to evaluate the efficacy and safety of different immunotherapy (IO) combinations, either with another IO (IO-IO) or with an antiangiogenic (IO-TKI), versus sunitinib in the first-line setting in aRCC patients with favorable IMDC risk., Methods: We conducted a systematic search for evidence in PubMed, Ovid MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials published up to February 2021. The GRADE approach was used to assess the quality of evidence. Survival hazard ratios were extracted for analysis in the favorable-risk aRCC subgroup (IMDC). A sensitivity analysis was performed excluding trials of combination therapy without TKI., Results: Five randomized controlled phase III trials with a total of 1088 patients were included in the analysis. The studies compared different combinations versus sunitinib monotherapy. All clinical trials reported overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) data. Four out of five trials reported complete response (CR). There was no difference in OS nor PFS between treatment arms in the IMDC favorable-risk subgroup analysis (OS: HR = 1.07, 95% CI = 0.81-1.41; PFS: HR = 0.74, 95% CI = 0.46-1.19). A benefit in ORR and CR was found for combination therapy vs. sunitinib (ORR: HR = 1.89, 95% CI = 1.29-2.76; CR: HR = 3.58, 95% CI = 2.04-6.28). In the sensitivity analysis, including only IO-TKI vs. sunitinib, no difference in OS was found; however, an advantage in PFS was observed (OS: HR = 0.99, 95% CI 0.69-1.43; PFS: HR = 0.60 (0.45-0.81). The safety profile reported is consistent with previous reports. We did not find differences in the incidence of any adverse event (AE) or of grade ≥3 AEs., Conclusion: This meta-analysis shows that combinations of IO-KI as first-line treatment in favorable-IMDC-risk aRCC improve PFS, ORR, and CR, but not OS, versus sunitinib.

Immune-checkpoint inhibitor-based therapy has revolutionized the natural history of metastatic renal cell carcinoma (mRCC) providing better survival outcomes, higher rates of complete responses (CR) and durable remissions. Along with these advances, new challenges have emerged. RECIST and new immune-response criteria may be equivocal identifying complete responses. How to define a durable response and what is the optimal treatment duration remains unclear. Furthermore, the real value of a complete and deep response, whether or not it can be considered curation and whether or not immunotherapy discontinuation should be considered after complete response, are questions that remain open. The present article reviews the current evidence regarding the impact and challenges of managing complete and durable responses in mRCC treated with immune-checkpoint inhibitors., (Copyright © 2021 Elsevier Ltd.

Introduction: Although increasing numbers of therapies with proven survival benefits have become available for metastatic castration-resistant prostate cancer (mCRPC), including radium-223, there is still a need for reliable biomarkers that provide information about clinically meaningful outcomes and treatment responses., Materials and Methods: This study was a translational study that was conducted prospectively by the Spanish Oncology Genito-Urinary Group and included 45 patients with histologically confirmed mCRPC who were treated with radium-223. The primary response outcome was defined by a decline in circulating tumor cells (CTCs) of > 50% from baseline or a CTC count of ≤ 5 cells/7.5 mL at cycle 3 of radium-223. We also assessed response according to prostate-specific antigen and alkaline phosphatase levels. CTCs were evaluated as prognostic factor for treatment completion with radium-223 treatment. Kaplan-Meier estimates of survival were calculated for the global population and were correlated with biomarker response outcomes., Results: Significantly, more patients with baseline CTC counts ≤ 5/7.5 mL, which are indicative of better prognoses, completed the 6 injections of therapy than those with CTC counts > 5 (16/22; 73% vs. 6/20; 30%, respectively; P = .012). The median overall survival was 16 months. Survival was significantly decreased in patients with baseline CTC counts > 5 cells/7.5 mL (7 months; P = .026) and baseline alkaline phosphatase levels ≥ 220 U/L (8 months; P = .028)., Conclusions: CTCs hold significant promise as a prognostic factor for survival and completing treatment prior to the initiation of bone-targeted radium-223 therapy. These findings may help to guide the use of radium-223 in patients with mCRPC., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Traditionally, bladder cancer has been classified based on histology features. Recently, some works have proposed a molecular classification of invasive bladder tumors. To determine whether proteomics can define molecular subtypes of  muscle invasive urothelial cancer (MIUC) and allow evaluating the status of biological processes and its clinical value. 58 MIUC patients who underwent curative surgical resection at our institution between 2006 and 2012 were included. Proteome was evaluated by high-throughput proteomics in routinely archive FFPE tumor tissue. New molecular subgroups were defined. Functional structure and individual proteins prognostic value were evaluated and correlated with clinicopathologic parameters. 1,453 proteins were quantified, leading to two MIUC molecular subgroups. A protein-based functional structure was defined, including several nodes with specific biological activity. The functional structure showed differences between subtypes in metabolism, focal adhesion, RNA and splicing nodes. Focal adhesion node has prognostic value in the whole population. A 6-protein prognostic signature, associated with higher risk of relapse (5 year DFS 70% versus 20%) was defined. Additionally, we identified two MIUC subtypes groups. Prognostic information provided by pathologic characteristics is not enough to understand MIUC behavior. Proteomics analysis may enhance our understanding of prognostic and classification. These findings can lead to improving diagnosis and treatment selection in these patients.

This paper aims to identify the concentrations of PAHs in the sediments of four coastal zones in Lebanon and determine their possible sources and effects. For each region (Tripoli, Jounieh, Dora, and Tyre), sampling, lyophilization, Soxhlet extraction, rotary evaporation, and gas chromatography were performed on 11, 10, 7, and 11 samples, respectively. The total PAHs concentrations ranged from 1.22 to 731.93μg/kg dry weight. The lowest concentrations were found in Tyre and the highest in Dora and Jounieh. The level of PAHs was classified as low to moderate and their source was mainly pyrogenic., (Copyright © 2016 Elsevier Ltd. All rights reserved.)
