Prognostic Influence of Internal Mammary Node Drainage in Patients with Early-stage Breast Cancer.

Background: The management of internal mammary nodes (IMNs) during multidisciplinary treatment of breast cancer has been debated for the last four decades without unequivocal conclusion.

Patients And Methods: We retrospectively reviewed patients with breast cancer who underwent sentinel lymph node biopsy at our center from 2008 until 2012. IMN drainage was assessed as a potential risk factor for local and distant disease recurrence.

Predictive parameters for internal mammary node drainage in patients with early breast cancer.

Introduction: Breast cancer treatment currently represents one of the biggest challenges in clinical oncology. The gold standard for axillary lymph node management is to perform sentinel node biopsy to avoid axillary dissection and its sequelae. The detection of radiocolloid flow outside the axillary nodes is a diagnostic and therapeutic challenge.

[Patient with atypical neurocytoma - case report].

Background: Neurocytoma represents a rare tumor of the central nervous system usually slowly growing and generally with good prognosis after surgical resection with or without adjuvant radiotherapy.

Case: A 25-year- old woman presented with sudden fainting. During the initial workup, brain CT was completed with finding of tumor inside the third ventricle spreading into both lateral ventricles.

Significance of resection margin as a risk factor for local control of early stage breast cancer.

Introduction: Breast conserving surgery combined with sentinel node biopsy represents currently the gold standard of treatment for early breast cancer. Although breast conserving surgery has been a widely accepted method for many years, there remain some highly controversial unresolved issues. The present analysis focused on the resection margin as one of the key factors for local control of the disease.

Internal mammary node management in breast cancer. A review.

Background: Internal mammary nodes visualized during sentinel node biopsy for breast cancer, remain an unresolved management issue. Further, both internal mammary node (IMN) radiotherapy and biopsy have attendant risks and hence should be used with caution. The purpose of this review is to highlight the available data and evidence.

[Breast cancer adjuvant radiotherapy using active breathing control-moderate inspiration breath-hold - a case report].

Background: Chest movements during the breathing cycle represent a significant problem during radiotherapy of target volumes in the chest. There are several methods how to solve this problem.

Case: We have used Active breathing control-moderate inspiration breath-hold device in the case of adjuvant treatment of breast cancer.

Omission of adjuvant radiation therapy in elderly patients with low risk breast cancer undergoing breast-conserving surgery--two center experience.

Introduction: Breast cancer is, now often diagnosed in patients older than 70 years due to longer life expectancy. The usual treatment is mastectomy to obviate radiotherapy or breast-conserving surgery followed by radiotherapy. The aim of this study was to investigate the need for adjuvant radiotherapy in older patients and the consequences of omitting radiotherapy following conservative surgery.

Hydride mobility in trinuclear sulfido clusters with the core [Rh3(μ-H)(μ3-S)2]: molecular models for hydrogen migration on metal sulfide hydrotreating catalysts.

The treatment of [{Rh(μ-SH){P(OPh)(3)}(2)}(2)] with [{M(μ-Cl)(diolef)}(2)] (diolef=diolefin) in the presence of NEt(3) affords the hydrido-sulfido clusters [Rh(3)(μ-H)(μ(3)-S)(2)(diolef){P(OPh)(3)}(4)] (diolef=1,5-cyclooctadiene (cod) for 1, 2,5-norbornadiene (nbd) for 2, and tetrafluorobenzo[5,6]bicyclo[2.2.2]octa-2,5,7-triene (tfb) for 3) and [Rh(2)Ir(μ-H)(μ(3)-S)(2)(cod){P(OPh)(3)}(4)] (4).

High tacticity control in organolanthanide polymerization catalysis: formation of isotactic poly(alpha-alkenes) with a chiral C3-symmetric thulium complex.

The thulium complexes [Tm((i)Pr-trisox)(CH(2)SiMe(2)R)(3)] (R = Me , Ph ) were synthesized from the thulium trialkyl precursors [Tm(CH(2)SiMe(2)R)(3)(thf)(2)]; reaction of with two equivalents of [Ph(3)C][B(C(6)F(5))(4)] gave a cationic complex 1c, which was found to polymerize 1-hexene, 1-heptene and 1-octene to give the corresponding polyolefins with moderate to good activities and with minimum isotacticity of 90%, 83% and 95%, respectively.
