Article Synopsis
- Lymphovascular invasion (LVI) is a key pathological feature associated with poor prognosis in cancers like breast carcinoma, and its assessment is now mandated in pathology reports.* -
- There are challenges in the consistent interpretation of LVI among pathologists, which leads to variability and affects reproducibility in assessments.* -
- While genomic assays have taken precedence in determining treatment strategies for breast cancer, LVI can still play a significant role in guiding adjuvant therapy in certain cases.*
Porous crystalline dipeptides absorb, reversibly from the gas phase, a series of volatile fluorinated ethers in use as anesthetics. Their vapor pressure was considerably reduced, with favorable guest capture and release. Variable channel sizes were customized for selective sorption and pressure thresholds were observed in the narrowest pores.

Background: Set-up errors represent a source of uncertainty in head and neck (H&N) cancer radiotherapy. The present study evaluated set-up accuracy with the use of cone-beam computed tomography (CBCT) in order to establish the proper clinical target volume (CTV) to planning target volume (PTV) margins to be adopted.
Methods: Local set-up accuracy was analysed for 44 H&N cancer patients since the implementation of CBCT.
Purpose: To quantify the impact of radiotherapy technique on cosmetic outcome and on 5-year local control rate of early breast cancer treated with conservative surgery and adjuvant radiation.
Methods And Materials: A total of 1,176 patients irradiated to the breast in 1997 were entered by eight centers into a prospective, observational study. Surgical procedure was quadrantectomy in 97% of patients, with axillary dissection performed in 96%; pT-stage was T1 in 81% and T2 in 19% of cases; pN-stage was N0 in 71%, N + (1-3) in 21%, and N + (>3) in 8% of cases.
