Multicenter Study
Outcomes for women with ductal carcinoma-in-situ and a positive sentinel node: a multi-institutional audit.
A positive sentinel lymph node (SLN) has been reported in 6% to 13% of patients with ductal carcinoma in situ (DCIS). Although it is well established that nodal status for invasive disease is prognostically important, the clinical relevance of a positive SLN in patients with DCIS remains undetermined. ⋯ SLN biopsy for high-risk DCIS patients is a mean of detecting those who may have unrecognized invasive disease and therefore are at risk for distant disease.

Breast cancer is currently viewed as a heterogeneous disease made up of various subtypes, with distinct differences in prognosis. Our goal was to study the distribution and to characterize the clinical and biological factors that influence the behavior and clinical management of the different molecular breast cancer subtypes in premenopausal African-American women. ⋯ The high prevalence of the basal-cell-like subtype in young premenopausal African-American women aged <35 years may contribute to the poorer prognosis observed in this cohort of African-American women.

Multicystic peritoneal mesothelioma (MPM) and well-differentiated papillary peritoneal mesothelioma (WDPPM) are exceedingly uncommon lesions with uncertain malignant potential and no uniform treatment strategy. The aim of the current study was to review our experience with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) in these clinical settings. ⋯ MPM and WDPPM are borderline tumors capable of transformation into potentially lethal processes. Definitive tumor eradication by means of cytoreduction and HIPEC seems more effective than debulking surgery in preventing disease recurrence or transition to aggressive malignancies.

Early age at onset is often considered a poor prognostic factor for colon cancer. The aim of this study was to determine the association between age, clinicopathologic features, adjuvant therapy, and outcomes following colon cancer resection. ⋯ Younger patients undergoing complete resection of stage I-III colon cancer had DSS similar to older patients. However, younger patients had more nodes retrieved from their specimens and were more likely to receive adjuvant therapy, especially for node-negative disease. These factors may have contributed to their overall favorable outcome.

Comparative Study
Occult breast lesion localization plus sentinel node biopsy (SNOLL): experience with 959 patients at the European Institute of Oncology.
Non-palpable breast lesions are diagnosed frequently posing the problem of localization and removal. When such lesions are malignant, axillary node status must be determined. We report our experience using radio-guided occult lesion localization (ROLL) for locating and removing non-palpable breast lesions together with sentinel node biopsy (SNB) to assess axillary status. We call the technique SNOLL. ⋯ In SNOLL the injection procedures are performed separately, but both lesion and SNs are removed together; axillary dissection is performed if the SN is positive, thus definitive treatment of malignant non-palpable lesions occurs in a single surgical session.
