  • Immune checkpoint inhibitors for the treatment of glioblastoma: Where we
           are

    • Authors: Bryan Lu, Senxi Du, Xiao-Tang Kong
      First page: 7
      Abstract: Despite a history of frequent challenges and roadblocks, there has been recent excitement in the treatment of human cancer, specifically regarding the remarkable efficacy of various immune checkpoint inhibitors including programmed cell death protein 1 (PD-1), programmed cell death ligand 1 (PD-L1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) blockers in treating metastatic melanoma, non-small cell lung cancer, and other malignant growths. However, treatment of glioblastoma multiforme (GBM) with immune checkpoint inhibitors so far has not been shown to be as successful in several randomized clinical trials as in other cancer with the exception of one pilot study that found promising results by neoadjuvant administration of Pembrolizimab for the treatment of recurrent GBM. Our article will review the current status of immune checkpoint inhibitors for the treatment of GBM.

  • Tumor associated macrophages and its nanovesicles: Immunological insights
           in cerebral glioma

    • Authors: Turano E, Farinazzo A, El Mously S, Calabria F, Jugerson I, Bonetti B, Bazzoli E
      First page: 14
      Abstract: Purpose: The immune system has a key role in glioma progression, especially the tumor associated macrophages (TAMs). In-vivo, we aimed to study the total TAMs and differential M1 and M2 TAM infiltration in low grade (LGG) versus high grade gliomas (HGG). Also, we investigated the implication of total TAMs and differential M1 and M2 TAMs infiltration on glioma progression. In-vitro, we studied the effect of soluble factors present in nanovesicles (NV) released from M1 TAMs on the fate of glioma cells.
      Methods: In-vivo, we performed immunohistochemistry using iNOS and CD163 (markers for M1 and M2 respectively). In-vitro, we polarized the human monocytes U937 cell line into M1, we isolated the NV from the M1-conditioned medium (CM) by centrifugation and filtration; then, the protein content of the NV was quantified by the protein assay. We added M1-NV on U251 glioma cells and we studied the cellular activation of glioma cells using the MTT assay. To assess the apoptosis of U251, we used the flow-cytometry. Apoptotic cells were identified by annexin V and Propidium Iodide (markers for early and late apoptosis respectively).
      Results: in-vivo, there is an M1/M2 imbalance in early stages of glioma which is associated with earlier progression to high malignancy. Also, the higher M2 infiltration, the earlier is the progression. In-vitro, M1-NV had a more potent anti-tumor effect compared to its corresponding CM. We assume that our experimental results can be a future treatment for the cerebral glioma.

  • Role of EUS in management of pancreatic tumors: review of 70 patients

    • Authors: Ashraf Sobhy Zakaria, Mohammed Gamil, Hussein Okasha, Ali Hassan Mebed, Reda Hassan Tabashy
      First page: 15
      Abstract: Background: Endoscopic ultrasound (EUS) has gradually become the main stream method of the diagnosis and local treatment of pancreatic tumors. Endoscopic ultrasound (EUS) is frequently used in making the cytological diagnosis of pancreatic cancer and its great role in the pre-operative staging of pancreatic tumors.
      Objective: To evaluate the role of EUS in diagnosis and treatment of pancreatic tumors prospectively for 2 years study 2014-2015.
      Patients and methods: Prospective study including 70 patients who presented with pancreatic tumors underwent EUS at the endoscopy unit at Faculty of Medicine Cairo University and National Cancer Institute, Cairo University.
      Results: Out of 70 patients; median age was 55 years (range 32_73 years). Males were 32 (46%) and females were 38 (54%). Jaundice was the main symptom 47 (67%), clay colored stool 46 (65.7%), dark urine 47 (67%) and abdominal pain 50 (71%). There were 20 patients with benign disease and 50 patients with malignant disease. The following results showing the accuracy of the EUS in detecting malignant pancreatic tumors; Sensitivity: 96.0%, specificity: 75%, PPV: 90.6%, NPV: 88.2%, accuracy: 90.0%.
      Conclusion: EUS can clarify locoregional spread when CT/MR are equivocal. EUS Elastography is a new application in the field of the endosonography and seems to be able to differentiate fibrous and benign tissue from malignant lesions. The combination of superior detection, good staging, tissue diagnosis and potential therapy makes EUS guided FNA a cost-effective modality.

  • Retrospective analysis of prognostic value of neutrophils to lymphocyte
           ratio and platelet count in patients with colorectal carcinoma

    • Authors: Mohamed Elbassiouny, Dina Ragab, Ghada Refaat, Suhad A. Ali
      First page: 16
      Abstract: Background: Colorectal cancer (CRC) is the third most common cancer in men and second in women with 1.8 million new cases (1,026,000 men and 823, 3 women) and almost 881.000 deaths. Rates are substantially higher in males than in females Worldwide in 2018.
      Aim of the work: In this retrospective study we aimed to evaluate the prognostic impact of baseline NLR and platelet count on the clinicopathological factors and outcome in patients of all stages Colorectal cancer treated from 1st of January 2014 to the end of December 2016 in Department of Clinical Oncology and Nuclear Medicine, Ain Shams University hospitals, Cairo, Egypt.
      Patients and methods: Out of 409 patient’s medical records in the GI oncology unit, Ain Shams Clinical Oncology Department were reviewed from the period between 1st of January 2014 to 30 December 2016. Total neutrophils, lymphocytic, and platelets’ counts were available for only 169 patients. Study ended in 1st of August 2018 with median period of follow up of 27.5 month, ranging between 1/1/2014 to 1/8/2018. All patients (169) were pathologically proven colorectal adenocarcinoma, with age ranging from 18-75 years old (median age: 55.5 yrs.)
      Results: Out of 169 patients enrolled in this study, 124 patients were resectable and underwent curative surgeries, 44 patients tumour was right located and 80 patient’s tumour located in the left sided colon. 45 patients were metastatic from the start. Postoperative Platelets ≥ 310 in our study was statistically significant regarding OS, PFS and DFS (P values <.001, <.001 and 0.007) respectively. Pre-treatment platelet revealed more frequent thrombocytosis in metastatic group than locally advanced group, yet statistically was not significant (P Value = .066). Postoperative NLR ≥ 2 was significant regarding OS, PFS and DFS among 169 enrolled patients (P values <.001, .002 and <.001) respectively. In the multivariate analysis, elevated postoperative NLR was proven as both independent prognostic and predictor factor for DFS, PFS and OAS. (sig. =.03, .03, ≤ 0.001 respectively). And platelet count is both independent prognostic factor and predictor for both PFS, OS with significance =.04, =.03 respectively).
      Conclusion: Abnormal NLR ratio (≥ 2) acting as a prognostic and predictor of decrease in DFS, PFS and OS in all patients groups. It also showed that abnormal platelet count (≥ 310) is prognostic and predictor of significant decrease in PFS and OS. Multidisciplinary management is needed to aware surgeons about importance of adequate lymph node dissection, our study showed a statistically significant decrease in OAS in patients underwent inadequate LNs dissection.

  • Invasive papillary ductal carcinoma of the breast: A case report

    • Authors: Amani S Hadi, Gamal Abdul Hamid, Refaat Al-Areqee, Wafa Abdullah
      First page: 17
      Abstract: The general rate of intrusive papillary carcinoma (IPC) is uncommon, representing for less than 1-2 % of invasive breast cancers. They are most generally observed in postmenposal females and uncommon in males. Invasive papillary carcinomas are low grade tumors originating from large or dilated ducts. They are make out of all around outlined solid nodules of monotones neoplastic cell separated by network of fibrovascular cores, IPC is a remarkable sort of breast cancer and regarded of whether it is in-situ or invasive, it has brilliant prognosis. We presenting two cases of invasive papillary carcinoma in male and female; A case of 55years postmenoposal female who presented with history of left breast mass, which this mass notice after trauma same site for 1 year ago the mass gradually increase in size no tenderness, no signs of inflammation. Excisional biopsy was performed and specimen was histopathology diagnosed as invasive papillary carcinoma, left MRM was performed and histopathology diagnosis confirmed and without residual tumor seen in submitted slides and all submitted lymph nodes were free of tumor infiltration (0/14). IHC show ER and PR negative with HER-2 positive. The second case 70 years male presented with right breast mass and history of post-trauma since one year back with gradual increase in size, right radical mastectomy done and histopathology diagnosed as invasive papillary carcinoma, IHC was done ER and PR positive with HER2- negative.

  • Advanced and metastatic renal cell carcinoma – Ain Shams Clinical
           Oncology Department Experience

    • Authors: Ahmed Nagy, Mona Kamal, Hesham El Halawani
      First page: 18
      Abstract: Background: Renal cell carcinoma is a rare tumor and till recently few treatment options were available. It is poorly understood why people develop RCC since only a few etiologic factors have been clinically identified as risk factors for RCC.
      Purpose: To analyze our experience at Ain Shams University Clinical Oncology department in Egypt with patients presenting with advanced renal cell carcinoma to provide a correlations between clinic-pathological factors, treatment and survival outcomes.
      Methodology: Retrospective review of the data of 54 patients who were diagnosed as RCC and presented to Ain Shams University Clinical Oncology department in Egypt from 1 May 2013 till 1 May 2015. Descriptive and clinic-pathological data were described using simple and relative frequencies. Survival outcome for the patients will be described using Kaplan Meier curves stratified according to morphology, age group and treatment received.
      Results: The sample included 54 patients (53.7% were males) of whom 14.3% were less than 40 years and 3.7% were elderly (≥ 70 years old). The median age was 55.5 years (SD ± 13.6 , range 19-71). Median PFS was 6.5 months (SD ± 12.3846 Range 43) while the median OS was 13 months (SD ± 12.161 Range 46). PFS in patients aged below 55.5 years was 9 months (95% CI=6.509-11.491) compared to 4 months (95% CI=2.704-5.296) in older patients (p = .004). PFS in patients who achieved PR after sunitinb was 17 months (95% CI=6.916-27.084) compared to 5 months (95% CI=3.699-6.301) in patients who didn’t achieved PR (p < .001). OS in patients aged below 55.5 years was 15 months (95% CI=9.131-20.869) compared to 11 months (95% CI=8.947-13.053) in older patients (p = .012). Favorable pathology status was associated with prolonged OS of 14 months (95% CI= 9.403-18.597) versus 11 months (95% CI=8.363-13.637) for unfavourable pathology status (p = .11). Low grades histopathogy was associated with prolonged OS of 44 months (95% CI= 38.456-49.544) versus 12 months (95% CI=10.077-13.923) for higher grades (p = < .001).
      Conclusion: Multivariate analyses supported a conclusion that younger age was an independent prognostic factor for survival along with other known risk factors such as tumor grade and pathology status.

  • Detecting EGFR mutations (L858R, T790M) using allele specific multiplex
           sequencing: A comparison with Pyrosequencing and TruSeq

    • Authors: Dilanthi Vinayagamoorthy, Jennifer Walsh, Kierra Gipson, Fei Ye, Minghao Zhong, Qin Dahui, Thuraiayah Vinayagamoorthy
      First page: 19
      Abstract: We are presenting an evaluation of Allele Specific Multiplex Sequencing (ASMS) to detect two EGFR somatic mutations (L858R, T790M). Late stage lung cancer samples were tested for both EGFR mutations and were compared to either pyrosequencing or TruSeq. The analytical lower limit of detection (LLOD) for the ASMS-L858R assay was found to be 36 copies, and 72 copies for the ASMS-T790M assay. The forty-one FFPE samples that were tested for T790M showed 100% concordance with the respective comparative method. The forty-five FFPE samples tested previously by Truseq for L858R showed 100% concordance with ASMS. Out of the twenty L858R samples previously tested by pyrosequencing, there was 95% concordance with ASMS. Additionally, twenty-one normal blood samples were tested by ASMS were found to be negative for L858R and T790M. In conclusion, the detection of L858R and T790M by ASMS are in acceptable concordance with both pyrosequencing and TruSeq in detecting EGFR mutations from late stage lung cancer. Further, ASMS was able to detect EGFR (L858R) with 10 picograms (3 copies gDNA) of FFPE extracted DNA, and hence could be used to detect mutations from samples carrying low copy numbers.

  • Prognostic value of VEGFR2 immunoexpression in glioblastoma

    • Authors: Gemma Issus, Sergi Mojal, Joan Gibert, Pilar Navarro, Montserrat Arumi-Uria, Dolores Naranjo-Hans, Beatriz Bellosillo, Maria Martínez-Garcia, Francesc Alameda
      First page: 1
      Abstract: Glioblastoma is the most frequent and aggressive primary tumor of the central nervous system. Prognosis is poor, with a median survival of 15 months after diagnosis. Various tumor biomarkers show prognostic value for glioblastomas, including VEGFR2, which is a receptor of VEGF related to the growth of the blood vessel network. VEGFR2 expression associates with poor prognosis in some tumors. Here we studied the prognostic value of the VEGFR2 immunohistochemical expression in glioblastoma. We used tissue microarrays to analyze 45 surgically excised samples from glioblastomas. Clinical data (age, sex, and Karnofsky Performance Status [KPS]) and morphological data (tumor necrosis, palisading, and vascular thrombosis) were collected. We performed a molecular study of MGMT and IDH1 expression (which are potential prognostic factors for glioblastomas) and an immunohistochemical study of VEGFR2 expression. Our results indicate that age, KPS, tumor necrosis, vascular thrombosis, treatment (STUPP versus other), and VEGFR2 immunoreactivity were related to prognosis (p < .005). In a multivariate analysis, only age > 65 years (Hazard Ratio (HR) (95% CI): 4.9 (2.1–11.4), p < .01), and VEGFR2 immunoexpression (HR (95% CI): 2.8 (1.3–6.1), p = .008), were found to have a statistically significant relation to prognosis. We conclude that immunohistochemical evaluation of VEGFR2 provides added prognostic value to the study of glioblastoma.
