Case report: Immunotherapy inducing unexpected overall survival in choroidal melanoma: about a case.

Choroidal melanoma (CM) is the most common malignant ocular tumor in adults. The current treatment of metastatic CM is limited by the intrinsic resistance of CM to conventional systemic therapies. Immunotherapy alone or in association with cytotoxic treatment became a realist option treatment.

Incidence and associated factors of cetuximab-induced hypersensitivity infusion reactions in 1392 cancer patients treated in four French areas: a possible association with Lyme disease?

Background: Previous studies have observed an increased incidence of Cetuximab-induced hypersensitivity infusion reactions (CI-IRs) in the southeastern states of the USA. Tick's bites were suspected of generating cross-reactions between cetuximab and alpha-gal. This study aims was to describe the incidence and associated risk factors of CI-IRs, in the French areas chosen according to their Lyme disease incidence.

Molecular Landscape of the Coagulome of Oral Squamous Cell Carcinoma.

Background: Hemostatic complications, ranging from thromboembolism to bleeding, are a significant source of morbidity and mortality in cancer patients. The tumor coagulome represents the multiple genes and proteins that locally contribute to the equilibrium between coagulation and fibrinolysis. We aimed to study the coagulome of Oral Squamous Cell Carcinoma (OSCC) and examine its link to the tumor microenvironment (TME).

Non-Invasive Ultrasonic Description of Tumor Evolution.

Purpose: There is a clinical need to better non-invasively characterize the tumor microenvironment in order to reveal evidence of early tumor response to therapy and to better understand therapeutic response. The goals of this work are first to compare the sensitivity to modifications occurring during tumor growth for measurements of tumor volume, immunohistochemistry parameters, and emerging ultrasound parameters (Shear Wave Elastography (SWE) and dynamic Contrast-Enhanced Ultrasound (CEUS)), and secondly, to study the link between the different parameters.

Methods: Five different groups of 9 to 10 BALB/c female mice with subcutaneous CT26 tumors were imaged using B-mode morphological imaging, SWE, and CEUS at different dates.

Survival of Patients with Epidermal Growth Factor Receptor-Mutated Metastatic Non-Small Cell Lung Cancer Treated beyond the Second Line in the Tyrosine Kinase Inhibitor Era.

Background: The identification of activating mutations in specific genes led to the development of targeted therapies for NSCLC. TKI directed against EGFR-mutations were the first to prove their major efficacy. Medical associations recommend their use as first and second-line metastatic treatments in EGFR-mutated patients.

DNA damage response- and JAK-dependent regulation of PD-L1 expression in head and neck squamous cell carcinoma (HNSCC) cells exposed to 5-fluorouracil (5-FU).

Objectives: The immune checkpoint molecule PD-L1 (CD274) is a crucial regulator of the tumor immune response. Its expression has been reported in the therapeutic context in Head and Neck Squamous Cell Carcinoma (HNSCC), but it remains unclear how therapeutically approved molecules regulate PD-L1 expression in HNSCC cells.

Materials And Methods: Three HNSCC cell lines (BICR6, PE/CA-PJ34 and PE/CA-PJ41) were used to analyze PD-L1 expression by immunoblotting, immunofluorescence and QPCR.

PARP inhibition in treatment of pancreatic cancer.

Introduction: Tumor control and survival of patients with metastatic pancreatic ductal adenocarcinoma (PDAC) has improved with more effective polychemotherapies. The identification of novel therapeutic targets is strongly needed in order to propose maintenance therapies that improve quality of life while maintaining tumor control.

Areas Covered: PDAC with mutations in homologous recombination repair genes such as are particularly sensitive to platinum agents.

Cervical bone pain revealing a bone metastatic colon cancer: A case report.

Colorectal cancer (CRC) is one of the most common malignancies worldwide, with common sites of metastases including abdominal lymph nodes, the liver and lungs. Bone metastases are known to be relatively rare sites of metastasis. The present study reported a patient with advanced colorectal cancer and metastatic colorectal cancer (mCRC) with atypical metastases presentation.

Glioblastoma and bevacizumab in elderly patients: Monocentric study.

Purpose: A retrospective monocentric comparison of progression-free survival, overall survival, clinical benefit and tolerability between elderly (age>70) and non-elderly (age ≤ 70) patients receiving bevacizumab for recurrent glioblastoma.

Methods: We analyzed 47 patients with recurrent glioblastoma receiving bevacizumab (10 mg/kg every 14 days) between January 2011 and January 2014. Bevacizumab was introduced for all patients at recurrence after a first-line treatment by temozolomide.

Monitoring Dual VEGF Inhibition in Human Pancreatic Tumor Xenografts With Dynamic Contrast-Enhanced Ultrasound.

Background: Association of drugs acting against different antiangiogenic mechanisms may increase therapeutic effect and reduce resistance. Noninvasive monitoring of changes in the antiangiogenic response of individual tumors could guide selection and administration of drug combinations. Noninvasive detection of early therapeutic response during dual, vertical targeting of the vascular endothelial growth factor pathway was investigated in an ectopic subcutaneous xenograft model for human pancreatic tumor.

Astonishing Evolution in Oropharyngeal Cancer with Immunotherapy: A Case Report.

Head and neck cancer is particular due to its infiltrative nature and lymphatic extension, with multidisciplinary treatment. Immunotherapy may be a brand-new therapeutic approach. We report a case of patient with advanced head and neck cancer resistant to cytotoxic treatment, with astonishing response to antibodies anti Programmed Death 1 (PD1).

Biosimilar filgrastim treatment patterns and prevention of febrile neutropenia: a prospective multicentre study in France in patients with solid tumours (the ZOHé study).

Background: The ZOHé study was a prospective, non-interventional, multicentre study in France to assess the use of biosimilar filgrastim Zarzio® (Sandoz filgrastim) in routine clinical practice in patients at risk of neutropenia-inducing chemotherapy (CT).

Methods: Patients ≥ 18 years undergoing CT for a malignant disease and with a first prescription for Zarzio® were enrolled in two cohorts according to tumour type: solid tumour or haematological malignancy; results from the solid tumour cohort are reported here. Analyses primarily described the prescription and use of Zarzio® in current practice, and also included identification of factors linked to prescription for primary prophylaxis and comparison of Zarzio® use in relation to European Organisation for Research and Treatment of Cancer (EORTC) guidelines.

Primary breast cancer relapse as metastasis to the cervix uteri: A case report.

Metastasis of non-gynaecological tumours to the cervix is a rare event, and metastasis from breast cancer is even rarer, with only a limited number of such cases reported in the literature to date. We herein report the case of an 86-year-old female patient who had undergone mastectomy and axillary lymphadenectomy for invasive ductal cell breast carcinoma 2 years prior, followed by adjuvant hormonal therapy with letrozole. During hospitalization for anemia associated with an inflammatory syndrome and abdominal pain with menorrhagia, an abdominal ultrasound examination revealed a suspicious uterine mass with irregular contours and abnormal vascularization with associated increase of the blood level of cancer antigen 15-3 to 34 kU/l.

Sternocleidomastoid muscle metastasis of breast cancer: case report.

The authors report a case of 84-year-old women, with dysphagia to liquids and solid foods, and with infiltration of right stemocleidomastoid muscle that compressed the upper third of the esophagus to the thoracic hull. The biopsy of sternocleidomastoid muscle permitted the diagnosis of metastatic breast cancer relapse after 22 years.

Peritoneal tuberculosis associated with adrenocorticol primitive neoplasm mimicking a peritoneal carcinosis: a case report.

The authors report a case of women, 51-year-old that presented with peritoneal tuberculosis, with concomitant adrenocortical primitive neoplasm, mistaken as peritoneal carcinomatosis, due to the failure of correct histological analysis. In fact, the critical life status, associated to increases of CA 125, typical imaging of peritoneal carcinomatosis, and presence of 75% atypical cells in ascitic fluid, induced to begin chemotherapy.

Adherence to treatment guidelines for cancer-associated thrombosis: a French hospital-based cohort study.

Purpose: French 2008 treatment guidelines recommend low-molecular-weight heparins (LMWH) for the treatment of cancer-associated thrombosis (CAT) with treatment duration of at least 3 months and up to 6 months and beyond if cancer remains active. Our aim was to assess adherence to guidelines in hospital clinical practice.

Methods: The French hospital database (PMSI) was used to identify patients with CAT admitted to three hospitals of the Paris region to be included in a retrospective cohort study.

VEGFR2-Targeted Contrast-Enhanced Ultrasound to Distinguish between Two Anti-Angiogenic Treatments.

The aim of this study was to evaluate the capacity of BR55, an ultrasound contrast agent specifically targeting vascular endothelial growth factor receptor 2 (VEGFR2), to distinguish the specific anti-VEGFR2 therapy effect of sunitinib from other anti-angiogenic effects of a therapy (imatinib) that does not directly inhibit VEGFR2. Sunitinib, imatinib and placebo were administered daily for 11 d (264 h) to 45 BalbC mice bearing ectopic CT26 murine colorectal carcinomas. During the course of therapy, B-mode ultrasound, contrast-enhanced ultrasound and VEGFR2-targeted contrast-enhanced ultrasound were performed to assess tumor morphology, vascularization and VEGFR2 expression, respectively.

mTOR-inhibitor treatment of metastatic renal cell carcinoma: contribution of Choi and modified Choi criteria assessed in 2D or 3D to evaluate tumor response.

Purpose: To determine whether 2D or 3D Choi and modified Choi (mChoi) criteria could assess the efficacy of everolimus against metastatic renal cell carcinoma (mRCC).

Methods: RECIST-1.1, Choi, and mChoi criteria were applied retrospectively to analyse baseline and 2-month contrast-enhanced computed tomography (CECT) images in 48 patients with mRCC enrolled in the everolimus arm of the French randomized double-blind multicentre phase III trial comparing everolimus versus placebo (RECORD-1).

Echo-power estimation from log-compressed video data in dynamic contrast-enhanced ultrasound imaging.

Ultrasound (US) scanners typically apply lossy, non-linear modifications to the US data for visualization purposes. The resulting images are then stored as compressed video data. Some system manufacturers provide dedicated software for quantification purposes to eliminate such processing distortions, at least partially.

Optimisation of the tumour response threshold in patients treated with everolimus for metastatic renal cell carcinoma: analysis of response and progression-free survival in the RECORD-1 study.

Background And Objectives: Objective response as determined by Response Evaluation Criteria in Solid Tumors (RECIST) is low among patients with metastatic renal cell carcinoma (mRCC) treated with targeted agents, despite significantly improved progression-free survival (PFS). A modified response threshold may be more clinically meaningful than RECIST for identifying patients who may derive a PFS benefit from targeted therapy.

Patients And Methods: We performed a retrospective analysis of data from the phase III RECORD-1 trial of everolimus versus placebo in patients with mRCC who had failed sunitinib or sorafenib (ClinicalTrials.
