Pilot Study on the Use of Untargeted Metabolomic Fingerprinting of Liquid-Cytology Fluids as a Diagnostic Tool of Malignancy for Thyroid Nodules.

Although it is the gold standard for assessing the malignancy of thyroid nodules (TNs) preoperatively, the cytological analysis of fine-needle aspiration cytology (FNAC) samples results in 20-30% of cases in indeterminate lesions (ITNs). As two-thirds of these lesions will appear benign after diagnostic surgery, improved preoperative diagnostic methods need to be developed. In this pilot study, we evaluate if the metabolomic profiles of liquid-based (CytoRich) FNAC samples of benign and malignant nodules can allow the molecular diagnosis of TNs.

Validation of RUBY for Breast Cancer Knowledge Extraction From a Large French Electronic Medical Record System.

Purpose: RUBY is a tool for extracting clinical data on breast cancer from French medical records on the basis of named entity recognition models combined with keyword extraction and postprocessing rules. Although initial results showed a high precision of the system in extracting clinical information from surgery, pathology, and biopsy reports (≥92.7%) and good precision in extracting data from consultation reports (81.

SENODAY: A New Perspective of Handling Breast Cancer.

Background: To evaluate the feasibility of a same day breast cancer diagnosis and management protocol, consequently decreasing time to treatment and immediately reassuring patients with benign diagnosis.

Materials And Methods: A total of 60 women underwent breast exam during SENODAY in our cancer center between January 2020 and December 2022. Patients are first seen by a breast surgeon who mentions whether the patient's history and physical exam are suspicious of malignancy.

RUBY: Natural Language Processing of French Electronic Medical Records for Breast Cancer Research.

Purpose: Electronic medical records are a valuable source of information about patients' clinical status but are often free-text documents that require laborious manual review to be exploited. Techniques from computer science have been investigated, but the literature has marginally focused on non-English language texts. We developed RUBY, a tool designed in collaboration with IBM-France to automatically structure clinical information from French medical records of patients with breast cancer.

[2021 update of the GEFPICS' recommendations for HER2 status assessment in invasive breast cancer in France].

The last international guidelines on HER2 determination in breast cancer have been updated in 2018 by the American Society of Clinical Oncology and College of American Pathologists, on the basis of a twenty-year practice and results of numerous clinical trials. Moreover, the emerging HER2-low concept for 1+ and 2+ non amplified breast cancers lead to refine French practices for HER2 status assessment. The GEFPICS group, composed of expert pathologists, herein presents the latest French recommendations for HER2 status evaluation in breast cancer, taking into account the ASCO/CAP guidelines and introducing the HER2-low concept.

[Is preoperative axillary radio-cytology justified after ACOSOG Z001?].

Introduction: Invasive breast cancer without clinical adenopathy (cN0) is currently explored by the sentinel node (GS) technique, except in the case of positive preoperative radio-cytological screening, where axillary curage (CA) remains systematic from the outset. Since the publication of the ACOSOG-Z0011 trial, abstention from CA is possible in patients presenting less than three metastatic GS. As a result, the value of axillary radio-cytological screening is being questioned as it could potentially lead to axillary surgical over-treatment.

Phenotypic discordance between primary and metastatic breast cancer in the large-scale real-life multicenter French ESME cohort.

Expression of hormone receptor (HR) for estrogens (ER) and progesterone (PR) and HER2 remains the cornerstone to define the therapeutic strategy for breast cancer patients. We aimed to compare phenotypic profiles between matched primary and metastatic breast cancer (MBC) in the ESME database, a National real-life multicenter cohort of MBC patients. Patients with results available on both primary tumour and metastatic disease within 6 months of MBC diagnosis and before any tumour progression were eligible for the main analysis.

[Preoperative breast imaging review: Interests and limits of specialized validation in oncology].

Objectives: To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients.

Materials And Methods: Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images.

[GEFPICS' guidelines for management of breast cancer tissue samples in the neoadjuvant setting].

Neoadjuvant therapy is an increasing treatment option in the management of breast cancer. The tumor response to neoadjuvant therapy, especially the pathological complete response, is a validated endpoint frequently used in clinical trials. However, there is still a lack of standardization for the surgical specimen management in the neoadjuvant setting.

Robotic Stereotactic Boost in Early Breast Cancer, a Phase 2 Trial.

Purpose: To evaluate the feasibility and toxicity of a single-fraction 8-Gy stereotactic boost after whole-breast irradiation in early breast cancer. The primary aim of this phase 2 study was to evaluate cutaneous breast toxicity using National Cancer Institute Common Terminology Criteria for Adverse Events (version 4) 3 months after the boost. Secondary objectives were local control, survival, and patient-reported quality of life using the European Organisation for Research and Treatment of Cancer QLQ-C30 and breast-specific European Organisation for Research and Treatment of Cancer QLQ-BR 23 questionnaires.

Objectives: To evaluate post-operative outcomes of salvage surgery in patients with recurrent OPSCC and to determine their predictive factors.

Contemporary therapeutic management of locally advanced hypopharyngeal cancer: oncologic and functional outcomes - a report on 100 cases.

Conclusion: A significant proportion of patients with locally advanced hypopharyngeal cancer could not be managed by larynx-sparing therapy. T4 stage is one of the main predictive factors of oncologic and functional outcomes.

Objectives: To analyze the therapeutic management of patients with locally advanced hypopharyngeal cancer in clinical practice and to report oncologic and functional outcomes.

[Pre-analytical stage for biomarker assessment in breast cancer: 2014 update of the GEFPICS' guidelines in France].

Biomarker assessment of breast cancer tumor samples is part of the routine workflow of pathology laboratories. International guidelines have recently been updated, with special regards to the pre-analytical steps that are critical for the quality of immunohistochemical and in situ hybridization procedures, whatever the biomarker analyzed. Fixation and specimen handling protocols must be standardized, validated and carefully tracked.

[2014 update of the GEFPICS' recommendations for HER2 status determination in breast cancers in France].

International guidelines on HER2 determination in breast cancer have just been updated by the American Society of Clinical Oncology (ASCO) and College of American Pathologists (CAP), on the basis of more than ten-year practice, results of clinical trials and concordance studies. The GEFPICS group, composed of expert pathologists in breast cancer, herein presents these recommendations, adapted to the French routine practice. These guidelines highlight the possible diagnosis difficulties with regards to HER2 status determination, such as intra-tumor heterogeneity, special histological subtypes and biomarker re-evaluation during metastatic relapse.

Long-term functional outcomes and quality of life after oncologic surgery and microvascular reconstruction in patients with oral or oropharyngeal cancer.

Conclusions: Surgery for oral or oropharyngeal cancer with free-flap reconstruction is associated with moderate but persistent functional and quality of life (QoL) problems. Patient age, tumor stage, tumor site, and radiotherapy were the main predictors of functional outcome.

Objectives: To evaluate long-term functional outcomes and QoL, and to determine their predictive factors in patients with oral or oropharyngeal cancer after oncologic surgery and free-flap reconstruction.

Diagnostic value of immunohistochemistry for the detection of the BRAF(V600E) mutation in papillary thyroid carcinoma: comparative analysis with three DNA-based assays.

Background: The aim of this study was to compare the detection of BRAF(V600E) by immunohistochemistry (IHC) using a mutation-specific antibody with molecular biology methods for evaluation of papillary thyroid carcinoma (PTC) patients.

Patients And Methods: This study concerned 198 consecutive conventional PTC patients, of which the majority were women (133/198; 67%), with a mean age of 56 years (range 19-79 years). BRAF mutation analysis was performed using DNA-based (direct sequencing, pyrosequencing, and SNaPshot) and IHC (VE1 antibody) methods.

In papillary thyroid carcinoma, TIMP-1 expression correlates with BRAF (V600E) mutation status and together with hypoxia-related proteins predicts aggressive behavior.

BRAF (V600E) causes upregulation of tissue inhibitor of metalloproteinase-1 (TIMP-1), which promotes cell invasion in papillary thyroid carcinoma (PTC). Hypoxia-inducible factor-1α (HIF- α) is regulated by hypoxia and also by the BRAF-mediated signaling pathway in PTC. We assessed the association of expression of TIMP-1, HIF-1α, and hypoxia-inducible carbonic anhydrase IX (CAIX) and XII (CAXII) with clinical parameters in PTC.

Conservative multimodal management of a primitive neuroectodermal tumor of the thyroid.

Primitive neuroectodermal tumors (PNET) represent 1% of sarcomas. Head and neck peripheral PNETs have an intermediate prognosis between abdominopelvic disease and extremities. We here report the case of a 40-year old male who presented with primitive neuroectodermal tumor of the thyroid and was treated by multimodal treatment, including surgery, chemotherapy and intermediate dose radiotherapy.

[Papillary meningioma: a very rare and aggressive variant of meningioma].

Papillary meningioma (MP) is a rare and aggressive variant of meningioma, occurring preferentially in young subjects. Histopathological features of papillary meningiomas are characterized by papillary or perivascular pseudorosette patterns. We report the case of a right frontal MP in a 16-year-old boy.

Significance of circulating tumor cell detection using the CellSearch system in patients with locally advanced head and neck squamous cell carcinoma.

The objective of this study was to evaluate the potential detection of circulating tumor cells (CTCs) using the CellSearch (CS) Assay™ in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) and then to identify the clinical factors predictive of the presence of CTCs. The presence and number of CTCs were determined using the CS system before treatment, and in 10 healthy individuals (control group). The CS system was able to successfully identify the presence of CTCs in 8 of 49 patients (16 %) before therapy.

Renal cell carcinoma and a constitutional t(11;22)(q23;q11.2): case report and review of the potential link between the constitutional t(11;22) and cancer.

We observed a t(11;22)(q23-24;q11.2-12) and monosomy 3 in renal tumor cells from a 72-year-old man. The hypothesis of a primitive peripheral neuroectodermal tumor (PPNET) located in the kidney was promptly excluded: Histologically, the tumor was a clear cell renal cell carcinoma (RCC) and we did not observe an EWSR1 gene rearrangement.

Impact of patient comorbidities on head and neck microvascular reconstruction. A report on 423 cases.

The aim of this study was to assess the impact of the different subtypes of patient comorbidities on the outcomes of head and neck microvascular reconstruction. A total of 423 patients who underwent head and neck free flap reconstruction in our institution between 2000 and 2010 were included in this retrospective study. The impact of the different subtypes of patient comorbidities (as defined by the Kaplan-Feinstein Index) and other global health status-related factors on free flap success, local and general complications, postoperative mortality and length of stay was assessed in univariate and multivariate analysis.

Regenerating I messenger RNA and protein expression in the failing human testis: a potential molecular prognostic marker of seminoma.

Infertility has been stated as a risk factor for testicular cancer; but currently, there is no prognostic indicator of tumor development from the pathologic testis with impaired spermatogenesis. Regenerating proteins are expressed in many human tissues including the testis, and their role in carcinogenesis has been well documented. In the present work, regenerating I messenger RNA and protein expression and cellular protein localization were studied in testicular biopsies of patients with normal (obstructive azoospermia) or impaired spermatogenesis (nonobstructive azoospermia) and in seminoma testis by quantitative reverse transcriptase-polymerase chain reaction, Western blot, and immunofluorescence analyses.
