Risk Factors Associated With Complications After Unilateral Immediate Breast Reconstruction: A French Prospective Multicenter Study.

Background/aim: For women who have undergone a mastectomy, breast reconstruction provides psychological as well as aesthetic benefits. Thus, many patients ask for an immediate breast reconstruction (IBR). The present study focuses on risk factors assiociated with complications after IBR.

Comparison of the histopathological results of the radioguided percutaneous microbiopsies and the operative specimens of soft tissue tumors of limbs, trunk and retroperitoneum.

Introduction: Suspicious lesions of sarcoma require preoperative biopsies. If surgical biopsies remain the gold standard, radioguided percutaneous microbiopsies are gaining an increasing importance. The purpose of this study was to compare histopathological results of percutaneous biopsies of soft tissues, trunk and retroperitoneal tumors with the histopathological results of operative specimens.

Advanced Techniques in Musculoskeletal Oncology: Perfusion, Diffusion, and Spectroscopy.

The imaging characterization of musculoskeletal tumors can be challenging, and a significant number of lesions remain indeterminate when conventional imaging protocols are used. In recent years, clinical availability of functional imaging methods has increased. Functional imaging has the potential to improve tumor detection, characterization, and follow-up.

Rates of Neoadjuvant Chemotherapy and Oncoplastic Surgery for Breast Cancer Surgery: A French National Survey.

Background: The current retrospective study was intended to obtain up-to-date and comprehensive data on surgical practice for breast cancer throughout France, including neoadjuvant chemotherapy (NAC) and the more recent surgical techniques of oncoplastic surgery (OPS).

Methods: In June 2011, e-mail surveys were sent to 33 nationally renowned breast cancer surgeons from French public or private hospitals. The questionnaire focused on all the new cases of breast cancer treated in 2010.

Focus on Merkel cell carcinoma: diagnosis and staging.

Merkel cell carcinoma is a rare lymphophilic skin tumor of neuroendocrine origin with the potential for rapid progression. Small, localized lesions are diagnosed and treated clinically, but advanced tumors often undergo imaging evaluation. Due to its rarity, radiologists are unaware of evocative imaging features and usually do not consider Merkel cell carcinoma in the differential diagnosis of soft tissue tumors.

Screening for vulnerability in older cancer patients: the ONCODAGE Prospective Multicenter Cohort Study.

Background: Geriatric Assessment is an appropriate method for identifying older cancer patients at risk of life-threatening events during therapy. Yet, it is underused in practice, mainly because it is time- and resource-consuming. This study aims to identify the best screening tool to identify older cancer patients requiring geriatric assessment by comparing the performance of two short assessment tools the G8 and the Vulnerable Elders Survey (VES-13).

[Metaplastic carcinomas of the breast: a morphological and immunohistochemical study].

Introduction: Metaplastic carcinomas of the breast are rare and form a heterogenic group of tumors, characterized by the presence of squamous or sarcomatoid differentiation.

Patient And Methods: In 23 cases, we study the main histoprognostic features, hormonal status, and the expression of HER2, CK5/6, CK14, p63, EGFR, beta-catenin, MUC1 and E-cadherin, the expression of this seven last antigens being also studied in nodal metastases.

Results: The different metaplastic types are spindle cell carcinoma (35%), squamous cell carcinoma (26%), osteo- or chondrosarcomatoid (11%) or mixed type (26%).

[The surgery after. . . retroperitoneal lymph node dissection and surgery of the residual masses after chemotherapy for advanced testicular cancer].

Thirty-six cases of retroperitoneal lymph node dissections for residual mass after chemotherapy for testicular cancer are reported. In a reference center, the recruitment is modified by the severity of the situations related to very big masses, tumors of poor prognosis and resistant tumors. Lymph node dissection is often atypical and surgery of metastatic residual masses is frequent (13 operations).

[Laparoscopic surgery and robot].

Twenty years ago, laparoscopic surgery entirely changed the traditional style of surgical operations. However, it was difficult to perform some interventions, particularly in restricted space or if acts of reconstruction are necessary. It was necessary to develop new technologies such robotic surgery.

Prevention of biliary lesions that may occur during radiofrequency ablation of the liver: study on the pig.

Objective: To prevent bile duct injury by using a cold 5% glucose isotonic solution cooling in the bile ducts when radiofrequency (RF) is performed in a porcine model.

Summary Background Data: Complications that may arise during liver RF ablation include biliary stenosis and abscesses.

Methods: The RITA 1500 generator was used for the experiments.

Results of preoperative lymphoscintigraphy for breast cancer are predictive of identification of axillary sentinel lymph nodes.

The aim of this study was to identify the variables associated with successful peroperative sentinel lymph node (SLN) localization. We studied 201 patients with T1, T2, N0 invasive breast cancer who underwent a SLN procedure from 1999 to 2003. Of these 201 patients, 55 underwent peritumoral and 146 underwent periareolar radioisotope injection before the blue dye injection.

[Use of sentinel lymph node technique in cutaneous melanoma: preliminary experience].

The aim of this study was to determine the contribution of the technique of sentinel lymph node (SLN) biopsy by preoperative lymphoscintigraphy and patent blue injection in management of primary cutaneous melanoma (MM). Sixty three patients with stade I primary MM were operated between March 1999 and January 2003. Preoperative lymphoscintigraphy was performed the day before surgery and peroperative patent blue injection was used to identify SLN.

[Is carotid resection a valuable option in advanced head and neck squamous cell carcinomas].

Head and neck squamous cell carcinomas may involve the carotid artery. Surgical treatment of these tumors is a difficult challenge, because of related morbidity and mortality. The aim of this study of international literature was to define the best preoperative and intraoperative strategy which permits carotid resection with acceptable neurologic risk.

[How to improve the initial management of adult patients with tumors of bone and soft tissues: the experience of a multidisciplinary committee from the Oncolor network before the distribution of regional guidelines].

Tumors of bone and soft tissues in adults are rare accounting in France for 2000 to 2500 new cases per year. These tumors are heterogenous and their diagnosis is made after first surgery. Therefore, an early pluridisciplinary approach, by physicians who have acquired an expertise in this field, is advised before any biopsy or surgical resection and at all the further step in the subfrequent management.
