Materials/methods This was a prospective study, done from 2012 to 2017 in glioblastoma patients to assess the efficacy of planned irradiation of ipsilateral PVZ and SVZ on survival outcomes. The clinical target volume included the tumour bed with a 1.5-2 cm margin, perilesional oedema and was expanded to encompass the ipsilateral PVZ (5 mm lateral expansion adjacent to the ventricles, including the SVZ, which was a 5 mm expansion lateral to lateral ventricle). The ipsilateral PVZ was planned to receive a dose of ≥50 Gy. Results 89 patients were recruited of which 74 patients were available for the analysis. Median age was 48 years. Mean doses to ipsilateral PVZ and SVZ were 56.2 and 55.1Gy, respectively. Median overall survival in the entire group was 13 months. There was no significant correlation between survival and doses to ipsilateral, contralateral, or bilateral PVZ and SVZ. Median survival was 16, 12 and 6 months for Eastern Cooperative -Oncology Group (ECOG) PS 1, 2 and 3, respectively (p = 0.05). Conclusion Planned irradiation of potential stem cell niches in the ipsilateral cerebral hemisphere did not result in improved survival as suggested by retrospective studies. Doses to contralateral or bilateral PVZ or SVZ also did not influence survival. © the authors; licensee ecancermedicalscience.Background HER2 status is a predictive biomarker of response to trastuzumab in advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma. However, there is relatively little known about the role of HER2 in resected gastric or GEJ adenocarcinoma in the Western population. Methods Retrospective, observational, single centre study of patients with gastric or GEJ adenocarcinoma undergoing surgery with curative intent between January 2007 and June 2014 in the University Hospital Complex of Santiago de Compostela. The expression of HER2 was determined by immunohistochemistry (IHC) using DAKO-HercepTest™ and gene amplification with DuoCISH using a DAKO-DuoCISH kit. The study of HER2 expression and amplification was carried out in all the patients and it was correlated with classic clinicopathological parameters, survival and recurrence pattern. Results 106 patients were included. HER2 expression was as follows 71.7% HER2 negative, 21.7% HER2 equivocal and 6.6% HER2 positive, or with HER2 overexpression. 13.2% of patients (14/106) had HER2 amplification by DuoCISH. A significant association was seen between overexpression and amplification of HER2 (p less then 0.001).HER2 positivity was associated with the intestinal subtype (p = 0.010) and a low grade of differentiation (p = 0.018). Likewise, HER2 was significantly associated with a worse prognosis overall survival (OS) 32.3 months HER2 positive versus 93.9 months HER2 negative (HR 0.42; confidence interval 95% 0.18-0.93; p = 0.028); and the presence of distant metastasis without accompanying locoregional recurrence (p = 0.048). Conclusion HER2 status defines a subgroup with differentiated clinicopathological characteristics, worse prognosis and distant dissemination, without accompanying locoregional recurrence, in patients with resected gastric or GEJ adenocarcinoma operated on in a Western population. © the authors; licensee ecancermedicalscience.Introduction For limited stage small cell lung cancer (LS-SCLC) where concurrent chemoradiotherapy is inappropriate due to tumour bulk, co-morbidities or performance status, sequential treatment using chemotherapy followed by radiotherapy is the standard of care. The outcomes are not well established; we assessed in a single institution, the survival of these patients, prognostic factors and compared to the limited existing literature. Materials and Method Retrospective data was collected on all 59 patients diagnosed with LS-SCLC from 2011 to 2016 who received chemotherapy consisting of Carboplatin or Cisplatin + Etoposide followed by thoracic radiotherapy (50 Gy in 25 fractions) +/- prophylactic cranial irradiation (PCI). Results Median age at diagnosis was 66 years (range 46-90). Patients received a median of four cycles of chemotherapy (range 1-6) and all the patients completed a full course of radiotherapy with only one patient experiencing grade >2 radiation induced toxicity. With a median follow up of 20.6 months, 45 patients had died with a median survival of 20.6 months. 2-year overall survival (OS) rates were 42%. Age using a cut-off of 65 was prognostic (median OS 25.6 months ≤65 years versus 14.1 months >65 years, p = 0.013) but gender, stage and receipt of PCI were not. Conclusions Most of the literature reporting outcome from sequential treatment in LS-SCLC is old and used a variety of radiotherapy regimens. Our data shows inferior outcomes to the gold standard concurrent chemoradiotherapy but support its usage in less fit patients with reasonable outcome observed. © the authors; licensee ecancermedicalscience.Armed conflict in Afghanistan has continued for close to 40 years and has devastated its health infrastructure. The lack of a cancer care infrastructure has meant that many Afghans seek cancer care in neighbouring countries, like Pakistan. There remains a significant lack of empirical data on the new therapeutic geographies of cancer in contemporary conflicts. This retrospective single centre study explores the therapeutic and clinical geographies of Afghan cancer patients who were treated at the Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC) in Lahore, Pakistan over a 22-year-period (1995 to 2017) covering major periods of conflict and relative peace. Data was available for 3,489 Afghan patients who received treatment at SKMCH&RC. The mean age at presentation was 42.7 years, and 60% were men. 30.2% came from Kabul and Nangarhar districts of Afghanistan, which have relatively short travel times to Pakistan, but patients from all parts of Afghanistan migrated to SKMCH&RC for treatment. Overall, 34.1% were diagnosed with upper gastrointestinal malignancies and 55.7% presented with late stage III/IV cancer. A wide range of treatments were provided, with 25.4% of patients receiving a combination of chemotherapy and radiation treatment. 52.7% of all patients were lost to follow-up. Outcomes were more favourable for children with cancer, 42% of whom had a complete response to therapy. Complex migration patterns, mixed political economies (refugees, forced and unforced migrants) and models of care that must be adapted to the realities of the patients rather than notional international standards all reflect the new therapeutic geographies that long-term conflict creates. This requires significant new domestic and international (e.g., United Nations High Commissioner for Refugees) policy and practises for providing cancer care in today's contemporary conflict ecosystems that frequently cross national borders. © the authors; licensee ecancermedicalscience.Purpose This study aims to increase the knowledge about the characteristics of cutaneous melanoma in Argentina, their association with the risk of having Breslow ≥1 mm and mortality trends for the period 2002-2017. Patients and methods Descriptive statistics and regression analyses were done for 10.199 cases within the Argentine Melanoma Registry in the period 2002-2018. Trends in age-standardised mortality rates (ASMR) were analysed using the Join point Regression Model. Results Cases showed lesions mainly located in males' trunk (37%) and in females' lower limbs (29%). The level of invasion was higher in males who also showed higher mortality. Cases from the North West and North East regions showed a major risk of Breslow >1 mm and harboured CM in lower limbs more frequently than in other regions. Nearly, 25% of tumours over 2 mm were in cases aged less then 50 years and 37.6% in patients ≥50 years. In the North West, North East and Patagonia, the frequency of cases in young people was higher than in oldere ecancermedicalscience.Genetic parenthood following cancer therapy is considered to be a major factor of quality of life. Given the rising proportion of patients surviving cancer due to improved therapeutic protocols, it is an issue of growing importance. Hence, the efforts to preserve fertility have motivated researchers to develop options for the paediatric population facing fertility-threatening cancer therapies. In prepubertal boys who do not yet produce sperm, cryo-banking of testicular tissue containing spermatogonial stem cells (SSCs) is the only viable option for future fertility preservation. While proposed in a number of clinics worldwide, however, this strategy remains still experimental. Transplanting the SSCs, or testicular tissue containing SSCs, back to the cured patient appears the most promising strategy. However, experiments performed with human testicular tissue in mice models reveal spermatogonial loss after transplantation, indicating the need for further optimisation of the transplantation procedure. The appro is urgently warranted to establish a clinical tool offering these boys a fertility restoration option in the future. This mini-review will focus on current achievements and future challenges of fertility preservation in young boys and underscore the next steps required to translate experimental strategies into clinical practice. © the authors; licensee ecancermedicalscience.The use of small molecule inhibitors in acute myeloid leukaemia (AML) has become ubiquitous with the US Food and Drug Administration approval of multiple agents between 2017 and 2018. Despite the promise, some of these indications are based on early efficacy data (phase I/II), and single-arm studies, and have not been tested in randomised trials. Furthermore, there are important limitations in the evidence that exists in randomised trials. This perspective aims to summarise the data that formed the basis for approval of gilteritinib, glasdegib, ivosidenib, enasidenib and venetoclax. It also aims to shed a light on some of the limitations in the evidence. Clinicians should exercise caution when using drugs that largely have yet to show an improvement in survival over the standard of care in AML. © the authors; licensee ecancermedicalscience.Background CAPOX regimen is a standard option in stage III adjuvant colon cancer. Gastrointestinal toxicity is well described with fluoropyrimidine regimens and can be life-threatening. selleck kinase inhibitor Identification of risk factors associated with severe gastrointestinal toxicity may help clinicians when choosing the adjuvant regimen. Materials and Methods We retrospectively analysed 61 patients treated with adjuvant CAPOX. Our primary objective was to estimate the incidence of severe chemotherapy-induced enterocolitis among patients treated with CAPOX. A secondary objective was to describe the main demographic and clinical characteristics of these patients. A univariate logistic regression was performed to estimate the odds ratio (OR) with a 95% CI to identify a predictor for severe enterocolitis. Results Grade 3 diarrhoea was reported in 10 patients (16.3%). Admissions to hospital due to toxicity occurred in nine cases. Reasons for hospitalisation were severe enterocolitis in eight cases (13.1%) and rectal bleeding plus thrombocytopenia in one case.
