[Show abstract][Hide abstract] ABSTRACT: Background
The sentinel node (SN) concept has brought numerous advantages to women with breast cancer. Sparing axillary node anatomy and physiology may enhance the cosmetic results of breast cancer conservative surgery, either owing to less breast edema or to a better tolerance to the effects of surgery and radiotherapy. Our aim was to compare the cosmetic outcome of two randomized groups of patients, on a subjective and objective basis.
A consecutive series of breast cancer patients (n = 60) submitted to partial mastectomy plus axillary dissection or partial mastectomy plus SN biopsy (included in a randomized trial) was photographed. Photos were analysed in three ways: by seven different observers according to seven features from poor to excellent; two observers estimated the percentage of breast retraction assessment (pBRA); or by the BCCT.core 1.0® software.
The panel subjective analysis showed a benefit in terms of the skin colour for the patients submitted to SN biopsy only. This group of patients did not show any advantage in terms of pBRA estimates even after the complex BCCT.core appraisal.
The sentinel node concept is not associated with improvements in the aesthetic outcome of breast cancer conservative treatment.

[Show abstract][Hide abstract] ABSTRACT: To determine the impact of axillary lymphadenectomy on regional recurrence, the overall and disease free survival, and upper limb morbidity in patients with breast cancer and negative sentinel node (SN).
A total of 176 patients with breast cancer and negative SN (pN0(sn)) were either randomised to lymphadenectomy (Group I) or to observation only (Group II). The triple technique was used to identify and remove the SN. Follow-up was carried out every 3 months for the first 3 years, and then every 6 months up to 5 years. Pain, numbness (paresthesia), limitations in shoulder mobility, and arm oedema were recorded.
No axillary lymph node recurrence was detected in the patients of Group II after 60 months follow up. The overall and disease free survival was similar in both groups. The proportion of patients with morbidity and who had more than two complications was significantly higher in Group I.
Axillary lymphadenectomy may be avoided in patients with negative SN without compromising lymph node extension studies and the patient treatment results. Axillary lymphadenectomy is associated with a higher morbidity of the upper limb compared to SN biopsy.

[Show abstract][Hide abstract] ABSTRACT: In order to assess the risk of non-sentinel node involvement in breast cancer patients, some prediction tools have been developed and tested. However, a wide range of results are observed. We tested a simplified clinical decision rule, against the complex nomogram created from the MSKCC sentinel node database.
Two single institutional consecutive series of patients with a positive SN, submitted to SN biopsy plus axillary dissection from June 1999 to October 2007, were evaluated. A receiver operating curve was drawn and the area under the curve was calculated as well as the negative predictive value for both tests, assuming discriminative values of 10 and 15%.
Considering the derivation series, our results showed an area under the curve of 0.69 for both our clinical decision rule and the MSKCC nomogram. The analysis of the validation series showed an area under the curve of 0.65 for our clinical decision rule and of 0.67 for the MSKCC nomogram. The nomogram results are inferior to those found in the original population and are similar to our clinical decision rule results.
Individual centres should develop and prospectively test their own clinical decision rules, based on their institutional Sentinel Node data.

[Show abstract][Hide abstract] ABSTRACT: Sentinel node (SN) biopsy to predict axillary involvement in breast cancer patients is a common practice. After a positive SN, additional metastases are present in an unpredictable percentage, as variable as 13-66%, of axillary clearances. Our aim is to define variables associated with non-sentinel node (NSN) metastases and to determine the predictive value of a derived clinical decision rule.
A consecutive series of patients with a positive SN submitted to SN biopsy plus axillary dissection was evaluated from June 1999 to December 2004 (n=143). Patient-, tumour- and SN-related variables were analysed in relation to the presence of additional metastasis. Univariate and multivariate analyses were done and predictive values of a clinical decision rule based on significant variables were estimated.
A total of 66 patients had metastasis in non-sentinel axillary nodes. No significant differences were present between this group and those with only the SN metastasised. Significant and independent association was found between NSN positivity and increasing tumour size, the presence of multifocality and the presence of peritumoral lymph channel invasion.
A first derivation of a simple rule based on tumour-related variables concurs to define the presence of NSN metastasis. Care should be taken when including SNrelated variables in these algorithms.

[Show abstract][Hide abstract] ABSTRACT: The Subclavian vein has been traditionally the vein of choice for central venous catheterization by general surgeons. Alternative settings for the introduction of totally implantable venous access devices (TIVAD) and the search for lower rates of morbidity led to the choice of other central veins. This study compares two different venous accesses, the subclavian (SC) versus the internal jugular (IJ), in terms of early and late morbidity.
This is a prospective, non-randomized, observational, uni-institutional (tertiary cancer centre) study. From March 2003 to March 2006, 1231 TIVADs were placed (1201 patients), in an ambulatory operating room, under vital signs and EKG monitoring, using local anaesthesia and without perioperative radiological control.
Of the 1231 TIVAD, 617 were inserted via the SC and 614 via the IJ vein. The two groups (SC vs. IJ) were comparable as to general patient characteristics. Immediate complications were more frequent in the SC than in the IJ approach (respectively, 5.0% vs. 1.5%; p<0.001); Catheter malposition occurred in 2.3% when using the SC vein and in 0.2% for the IJ (p=0.001). Long term morbidity was also more frequent in the SC than in the IJ group (respectively, 15.8%, 87/551, vs. 7.6%, 39/512; p<0.001). Venous thrombosis developed in 2.0% of patients with an SC TIVAD as compared to 0.6% with an IJ TIVAD (p=0.044). Catheter malfunction was significantly dependent on the vein used: SC - 9.4% vs. IJ - 4.3% (p=0.001).
Our results support the preferential use of the Internal Jugular vein for the insertion of TIVAD.
