Whole breast radiotherapy in cN0 early breast cancer patients with pathological sentinel lymph nodes (pN1mic, pN1a) without axillary dissection: preliminary results of the observational LISEN trial.

Purpose: Axillary management remains unclear when sentinel lymph node (SLN) results are positive in cN0 patients with breast cancer (BC). The trial ACOSOG Z0011 represented a revolution with axillary lymph node dissection (ALND) omission in SLN+ patients, despite critiques regarding non-uniformity of radiation fields. We conducted an observational study (LISEN) where whole breast radiotherapy (WBRT) was planned with tangential fields without nodal irradiation in patients eligible for the Z0011 trial.

Clinical outcomes in elderly rectal cancer patients treated with neoadjuvant chemoradiotherapy: impact of tumor regression grade : Tumor regression grade after neoadjuvant chemoradiotherapy in elderly rectal cancer patients.

Purpose: The effect of neoadjuvant chemoradiotherapy (CRT) and the relationship between pathological complete response (pCR) with clinical outcomes has been evaluated in elderly locally advanced rectal cancer (LARC) patients.

Methods: We retrospectively analyzed 117 LARC patients treated with conformal RT and concomitant fluoropirimidine-based chemotherapy. A dose of 4500 cGy, on the pelvis, up to 5500 cGy on the tumor was delivered.

Long-term outcome of neoadjuvant endocrine therapy with aromatase inhibitors in elderly women with hormone receptor-positive breast cancer.

Background: Aromatase inhibitors (AIs) are more effective than tamoxifen as neoadjuvant endocrine therapy (NET) for hormone receptor (HR)-positive breast cancer. Here we report the surgical and long-term outcome of elderly postmenopausal patients with locally advanced, HR-positive breast cancer treated with preoperative AIs.

Methods: Between January 2003 and December 2012, 144 postmenopausal patients inoperable with breast conservative surgery (BCS) received letrozole, anastrozole, or exemestane as NET.

Interobserver variability of clinical target volume delineation in soft-tissue sarcomas.

Purpose: The present observational study reports the results of a multi-institutional dummy-run designed to estimate the consistency of interobserver variability in clinical target volume delineation in two different cases of soft-tissue sarcomas in which postoperative and preoperative radiotherapy were prescribed, respectively. The purpose of this work was to quantify interobserver variability in routine clinical practice.

Patients And Methods: Two different cases of soft-tissues sarcomas were chosen: a case of postoperative and a case of preoperative radiation therapy.

The case of a patient affected by primary gliosarcoma and neuroendocrine pancreatic cancer with prolonged survival.

Primary gliosarcoma (PGS) is a rare neoplasm with a poor prognosis. It is considered as a variant of glioblastoma multiforme (GBM) and as a grade IV neoplasm. There is little evidence on the optimal therapy for this disease: treatment of PGS includes surgery, radiotherapy and chemotherapy, and often the same treatment used for GBM is employed for PGS.
