Association of Radial Margin Positivity With Colon Cancer

JAMA Surgery, 2015
In colon cancer, radial margin positivity (RMP) is defined as primary disease involvement at the cut edge of the mesentery or nonserosalized portions of the colon. Although extensively studied for rectal malignancies, RMP has unclear prognostic implications for tumors of the colon.To determine the effect of RMP on perioperative outcomes as well as ...

Frozen Sections for Positive Margins?

European Urology, 2006
Radical prostatectomy, or probably more accurately termed total prostatectomy, is one of the most common approaches for the treatment of clinically, organ-confined prostate cancer. Whether performed by an open (retropubic or perineal) or laparoscopic technique, perioperative morbidity has dramatically declined over the past two decades.

On a class of marginally stable positive-real systems

IEEE Transactions on Automatic Control, 1996
Summary: A class of marginally stable positive real systems is defined which is less restrictive than the previously published definitions of strictly positive real systems. A minimal realization and state-space characterization of such systems are presented, and it is proven that controllers belonging to this class robustly stabilize positive real ...

Marginality as a Societal Position of Religion

Sociology of Religion, 2002
Inherent in religion is an ironic tension between a predisposition, developed in early life, to see ultimate reality as nurturing, and an adult shared doubt about the claims of this world. This feature of religion leads to its flourishing in marginality and stagnating in an established condition.

[Conization with positive margins].

Contraception, fertilite, sexualite (1992), 1999
We received all conizations performed between 1986 and 1997. The incidence of positive margins conization for cervical intraepithelial neoplasia is 7.8% (23.8% in others studies). Persistent or recurrence disease occur only in 35% of cases; so new treatment is not always usefull and cytology and colposcopy are adequate for follow-up.

Positive Marginality: Antecedents and Consequences

Journal of Adult Development, 1998
This article presents evidence for the view that an important precursor to a feminist identity is a sense of one's own marginality plus a redefinition of what that marginality means. Choosing marginality appears to be a highly adaptive strategy for social activists who can “pass” as members of the dominant majority.

Radical prostatectomy: Positive surgical margins matter

Urologic Oncology: Seminars and Original Investigations, 2013
A positive surgical margin (PSM) in the radical prostatectomy (RP) specimen is associated with biochemical recurrence (BCR) and the need for adjuvant radiation therapy, and is a surrogate for surgical quality. We review the available data describing the identification, anatomy, and management of PSM after RP.A PubMed search (using English language as a

The Relationship of Breast Density and Positive Lumpectomy Margins

Annals of Surgical Oncology, 2019
A positive lumpectomy margin after breast-conserving surgery (BCS) is a significant predictor for ipsilateral cancer recurrence. The MarginProbe, a Food and Drug Administration (FDA)-approved device for intraoperative assessment of lumpectomy margins, is associated with a reduction in re-excision surgery.

Significance of a Positive Oesophageal Margin in Stomach Cancer

Australian and New Zealand Journal of Surgery, 2000
Background: A positive oesophageal margin is frequently encountered in total and proximal gastrectomies. It is controversial as to whether a positive oesophageal margin in gastrectomy predisposes to anastomotic dehiscence and loco‐regional recurrence. Its independent impact on survival has not been fully addressed.
