Long-term outcomes in stage IIIB breast cancer patients who achieved less than a pathological complete response (pCR) after primary chemotherapy.
2009
Abstract Learning Objectives After completing this course, the reader will be able to: Summarize the main risk factors for relapse in patients with T4 breast cancer after neoadjuvant chemotherapy.Evaluate the role of hormone receptors and HER-2 as determinants of risk of relapse after neoadjuvant treatment.Compare the difference in outcomes between patients who achieve less than pCR in relation to receptor status. This article is available for continuing medical education credit at CME.TheOncologist.com. Purpose. Pathological complete response (pCR) to primary chemotherapy is the main determinant for improved disease-free survival (DFS) and overall survival (OS). The primary endpoints of ou…
Human papillomavirus (HPV) DNA in primary cervical cancer and in cancer free pelvic lymph nodes--correlation with clinico-pathological parameters and…
2001
OBJECTIVE To assess whether the presence of human papilloma virus (HPV) DNA and/or several genotypes of HPV DNA in primary cervical cancer and cancer free pelvic lymph nodes are correlated with several clinicopathological parameters of well-defined prognostic significance and whether virological parameters are predictors of long-term survival in cancer patients. PATIENTS AND METHODS 223 cases of cervical cancer patients included in this retrospective study underwent follow-up evaluation. Survival and cause of death were examined for 204 (91.4%) patients, with a mean follow-up time of 4.4 years. HPV DNA was detected using the high sensitive polymerase chain reaction (PCR) method followed by …
Study of axillary lymph node asymmetry in a female population
2001
We analysed a large series of axillary lymph nodes, with and without metastases following radical mastectomy for breast cancer. We found left/right asymmetry in numbers of lymph nodes, and also asymmetry of lymph node dimensions, which could have been the caused by tumoral antigenic stimulation. The distribution of hyperplastic node patterns differed significantly.
The natural history of breast carcinoma in patients withor = 10 metastatic axillary lymph nodes before and after the advent of adjuvant therapy: a mu…
2005
BACKGROUND The majority of patients with breast carcinoma with ≥ 10 metastatic axillary lymph nodes (ALNs) develop recurrent disease within 5 years from diagnosis. The purpose of the current study, performed retrospectively, was to characterize the natural history of this subset of patients, both before and after the advent of adjuvant anthracycline-based chemotherapy and tamoxifen. METHODS Retrospectively, patients with primary breast carcinoma (N = 882) with ≥ 10 metastatic ALNs, treated between 1954 and 1998, were selected from 3 institutions: The University of Texas M. D. Anderson Cancer Center (Houston, TX); the Institut Gustave Roussy (Villejuif, France); and Hospital Clinico Universi…
Assessing the impact of CMF/FEC/FEC-DOC/ETC (dose-dense) adjuvant chemotherapy in dependency of positive axillary lymph nodes on survival: A retrospe…
2013
1074 Background: Adjuvant chemotherapy has changed dramatically in the last decades. Anthracycline-/taxane-based and dose-dense chemotherapy regimens improved survival in node positive breast cancer. This study tries to answer the following questions: (1) Are there differences in survival dependent on chemotherapy regimens in 0/0-3/4-10/<10 positive lymph nodes? (2) Is it possible to define a cut-off of positive lymph nodes for the use of Taxane-based and dose dense chemotherapy? Methods: This German is a multi-center [17 participating hospitals all are certified as breast cancer centers] retrospective cohort study. We included CMF (1.385), FEC (1.170), FEC-DOC (1.723), and dose-dense E…
DNA ploidy and S-phase fraction, but not p53 or NM23-H1 expression, predict outcome in colorectal cancer patients. Result of a 5-year prospective stu…
2002
Purpose: The aim of this study was to determine TP53 and NM23-H1 immunoreactivity, DNA ploidy, and S-phase fraction (SPF) in a series of 160 patients undergoing resective surgery for primary operable colorectal cancer (CRC) and to establish whether these alterations have any clinical value in predicting CRC patients' prognosis. Methods: TP53 and NM23-H1 expressions were evaluated on paraffin-embedded tissue by immunohistochemistry and DNA-ploidy and SPF on frozen tissue by flow-cytometric analysis. Results: The median follow-up time in our study group was 71 months (range 34-115 months). P53 protein expression was associated with distal tumors (P < 0.05) and DNA aneuploid tumors (P < …
Prediction of Non-sentinel Node Status in Patients with Melanoma and Positive Sentinel Node Biopsy: An Italian Melanoma Intergroup (IMI) Study
2018
Background and Purpose: Approximately 20% of melanoma patients harbor metastases in non-sentinel nodes (NSNs) after a positive sentinel node biopsy (SNB), and recent evidence questions the therapeutic benefit of completion lymph node dissection (CLND). We built a nomogram for prediction of NSN status in melanoma patients with positive SNB. Methods: Data on anthropometric and clinicopathological features of patients with cutaneous melanoma who underwent CLND after a positive SNB were collected from nine Italian centers. Multivariate logistic regression was utilized to identify predictors of NSN status in a training set, while model efficiency was validated in a validation set. Results: Data …
Predicting survival in node-positive prostate cancer after open, laparoscopic or robotic radical prostatectomy: A competing risk analysis of a multi-…
2016
Objectives: To investigate cancer-specific mortality and other-cause mortality in prostate cancer patients with nodal metastases. Methods: The study included 411 patients treated with radical prostatectomy and pelvic lymph node dissection for prostate cancer with lymph node metastases at 10 tertiary care centers between 1995 and 2014. Kaplan–Meier analyses were used to assess cancer-specific mortality-free survival rates at 8 years' follow up in the overall population, and after stratifying patients according to clinical and pathological parameters. Uni- and multivariable competing risk Cox regression analyses were used to assess cancer-specific mortality and other-cause mortality. Finally,…
Mesenteric Lymph Node Involvement in Advanced Ovarian Cancer Patients Undergoing Rectosigmoid Resection: Prognostic Role and Clinical Considerations
2014
Background: The aim of this retrospective study was to investigate the incidence of mesenteric lymph node (MLN) involvement, and its prognostic role in advanced ovarian cancer (OC). Methods: OC patients undergoing rectosigmoid resection during primary debulking surgery or interval debulking surgery were recorded. Progression-free survival (PFS) and overall survival were calculated from the date of diagnosis to the date of relapse/progression, death of disease, or the date of last follow-up. Results: MLNs were detected in 102/148 cases (68.9 %); the rate of MLN involvement was 47.0 %. The percentage of metastatic MLNs was higher in cases with >5 MLNs removed compared with cases with ≤5 MLNs …
Extranodal Extension of Nodal Metastases Is a Poor Prognostic Indicator in Gastric Cancer: a Systematic Review and Meta-analysis.
2016
Introduction: The extranodal extension (ENE) of nodal metastases (the extension of neoplastic cells through the nodal capsule into the perinodal soft tissue) is a histological feature that has been considered a prognostic factor in several cancers, but the role in gastric cancer was not yet investigated. We aimed to investigate the prognostic role of ENE in patients affected by gastric cancer through a systematic review and meta-analysis. Material and Methods: Two independent authors searched major databases until 09/30/2015 to identify studies providing data on gastric cancer patients’ prognostic parameters and comparing patients with ENE (ENE+) vs intra-nodal extension (ENE−). The data we…
