[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to evaluate the relationship of satisfaction with the cancer care doctor and health-related quality of life (HRQOL) among Latina breast cancer survivors (BCS) by (1) assessing whether satisfaction would be positively correlated with HRQOL and (2) assessing whether satisfaction would significantly influence HRQOL while controlling for covariates.
The cross-sectional study used self-report data from 117 Latina BCS. Satisfaction was measured with the Hall Satisfaction Index, and HRQOL was measured with the Functional Assessment of Cancer Therapy-General (FACT-G). Analyses included calculation of descriptive statistics, t tests, bivariate correlations, analyses of variance (ANOVAs), and multivariate analyses.
Latina BCS had high satisfaction and generally good HRQOL. The Hall Satisfaction Index total score was positively associated with FACT-G functional well-being (r=0.265, p=0.004). Multivariate analyses showed that the Hall Satisfaction Index total score was a significant predictor of FACT-G functional well-being (p=0.012). Employment status was also a significant predictor, where being employed or retired resulted in better functional well-being than being unemployed.
Latina BCS were quite satisfied with their cancer care doctors, and high levels of satisfaction with the cancer care doctor influenced functional well-being when confounding variables were controlled. Despite reportedly high satisfaction, Latina BCS did report barriers to satisfaction that could be considered cultural. Implications are discussed.

[Show abstract][Hide abstract] ABSTRACT: The study evaluated the association of religiosity/spirituality (R/S) and health-related quality of life (HRQOL) among Latina breast cancer survivors (BCS) in order to determine whether R/S would be positively correlated with HRQOL and whether R/S would significantly influence HRQOL.
The cross-sectional study utilized self-report data from 117 Latina BCS survivors. R/S was measured with the Systems of Belief Inventory-15 Revised (SBI-15R) and HRQOL was measured with the Functional Assessment of Cancer Therapy-General (FACT-G). Analyses included calculation of descriptive statistics, t-tests, bivariate correlations, and multivariate analyses.
Latina BCS had very high levels of R/S and generally good HRQOL. The SBI-15R total score was positively correlated with FACT-G social well-being (SWB) (r=0.266, p=0.005), relationship with doctor (RWD) (r=0.219, p=0.020), and functional well-being (FWB) (r=0.216, p=0.022). Multivariate analyses revealed that SBI-15R was a significant predictor of FACT-G FWB (p=0.041) and satisfaction with the relationship with the doctor (p=0.050), where higher levels of R/S predicted higher levels of well-being.
Latina BCS had very high levels of R/S, which were significantly, positively correlated with dimensions of HRQOL (SWB, FWB, RWD). Furthermore, these high levels of R/S predicted better FWB and satisfaction with the patient-doctor relationship while controlling for potentially confounding variables. Implications are discussed.
[Show abstract][Hide abstract] ABSTRACT: To increase accrual among Hispanics to the Cancer Genetics Network national cancer genetics registry.
Drawing from South Texas cancer registries, 444 Hispanic men and women were randomly assigned to one of three experimental conditions: standard direct-mailed procedures (X1), X1 plus culturally tailored materials (X2), and X2 plus interpersonal phone contact (X3). Participants were also surveyed about the effectiveness of the education materials and the phone contact. A refusal survey was provided for those who declined to join the study.
A total of 154 individuals joined the Cancer Genetics Network. The X3 condition yielded the greatest accrual (43.2%) compared to X1 (30.9%) and X2 (29.9%; p < 0.05). Tailored materials appeared to have no effect but were highly regarded. The main reasons for not participating were a lack of interest and time requirements.
Interpersonal communication can have a powerful effect on recruitment. However, more research is needed to determine the cost-efficacy of more labor-intensive approaches to registry accrual.

[Show abstract][Hide abstract] ABSTRACT: To provide a preliminary description of the interest, awareness, and perceptions of genetic testing among Hispanics with a family history of breast cancer
This cross-sectional pilot study used interpersonal structured interviews for data collection.
We interviewed 48 Hispanics without breast cancer but who had a family member with breast cancer; participants lived in San Antonio and the surrounding area.
The outcomes were interest in breast cancer genetic testing, awareness about genetic testing, perceived risk of carrying a breast cancer susceptibility gene, and the perceived benefits and risks associated with a genetic test.
Items previously used in research regarding interest and perceived genetic risk and a previously validated benefits and risks-limitations scale for genetic testing commonly used by other researchers were used to measure the outcomes.
Awareness of genetic testing for breast cancer susceptibility was very low, yet most (82%) participants were interested in a genetic test for breast cancer susceptibility. Participants were more likely to identify with the benefits than the potential risks of genetic testing. The most highly endorsed benefits were to know to take better care of one's self and to undergo more frequent screening.
Hispanics seem to have positive perceptions about genetic testing for breast cancer susceptibility. However, the high level of interest in genetic testing may be driven by a lack of knowledge about genetic testing. Culturally sensitive and appropriate educational programs about breast cancer genetic testing and the surrounding issues are needed for the Hispanic population.

[Show abstract][Hide abstract] ABSTRACT: Histologic margin positivity represents a significant source of adverse clinical outcome affecting breast conservation therapy for in situ or invasive malignancy. Elucidation of factors associated with positive margin status might clarify and improve local therapy strategies. In order to define our experience with margin positivity and to identify relevant pathologic criteria, we retrospectively analyzed the cases of 143 patients who underwent resections for carcinoma with intent of breast conservation between 1995 and 1999.
Histologic features and indices of biologic aggressiveness were compared among tumors resected with positive versus negative margins in order to determine whether such markers could be used to anticipate outcome.
Twenty-eight pathologic specimens were identified to possess histologically positive margins. Twenty-six patients underwent additional operative procedures. Of the 26 re-excision specimens, 17 (65%) contained residual malignancy. Statistical analysis demonstrated that margin positivity correlated with in situ histology and with Her 2/neu positivity.
These data suggest certain pathologic factors that may portend difficulty in achieving negative resection margins in patients in whom breast conservation therapy is considered.

[Show abstract][Hide abstract] ABSTRACT: Management of breast needle core biopsies diagnosed as atypical ductal hyperplasia, atypical lobular hyperplasia, and lobular carcinoma in situ is controversial. Current recommendations involve excisional biopsy to rule out ductal carcinoma in situ and/or invasive carcinoma, which have been reported in more than 50% of cases in some series.
To determine how frequently these diagnoses made on needle core biopsy are ultimately found to represent in situ or invasive carcinoma based on excisional biopsy specimens, in order to identify predictive factors.
One thousand eight hundred thirty-six image-guided needle core biopsies were performed between January 1, 1995 and May 1, 2001. Fifty-four (2.9%) patients diagnosed with atypical ductal hyperplasia (n = 36), atypical lobular hyperplasia (n = 12), atypical ductal hyperplasia + atypical lobular hyperplasia (n = 3), or lobular carcinoma in situ (n = 3) subsequently underwent breast excisions. Pathologic features were reviewed in each of the needle core biopsies using Page's criteria and were then correlated with excision specimens.
University medical center.
Review of the needle core biopsy cases with either ductal carcinoma in situ or invasive carcinoma + ductal carcinoma in situ on final excision showed that nucleoli were evident in most of the needle core cases, with foci of nuclear pleomorphism and individual cell necrosis or apoptosis.
A more precise diagnosis can be made by using strict criteria for atypical ductal hyperplasia versus ductal carcinoma in situ on needle core biopsy. Cytologic atypia, even if in a small area, particularly when there is apoptosis/individual cell necrosis, correlates with the finding of a more serious lesion on excision.

[Show abstract][Hide abstract] ABSTRACT: Sentinel lymph node mapping (SLNM) and neoadjuvant chemotherapy are becoming established components of therapy for selected patients with breast carcinoma. However, neoadjuvant therapy has been considered a relative contraindication to SLNM. In an effort to learn whether patients who have received preoperative chemotherapy can undergo accurate SLNM, we evaluated our experience with this technique.
From January 1997 to June 2000, SLNM and axillary lymph node dissection were concurrently performed in 35 patients who received preoperative chemotherapy. Mapping was performed with (99m)Tc sulfur colloid only in one patient and Lymphazurin dye only in 15 patients, and the two methods were combined in the remainder.
SLNM successfully identified a sentinel lymph node in 30 (86%) patients. Metastatic disease was identified in the sentinel lymph nodes of four patients during surgery. The intraoperative pathologic diagnosis proved to be correct in 19 (79%) of 24 patients. The final pathologic diagnosis of the sentinel lymph node reflected the status of the axillary contents in all patients in whom it was identified.
These results demonstrate that SLNM can be consistently performed in patients receiving preoperative chemotherapy for breast cancer, suggesting the utility of this technique in this patient population.

[Show abstract][Hide abstract] ABSTRACT: Pancreatic carcinoma resists chemotherapeutic mediation of apoptosis. Irofulven (MGI 114, 6-hydroxymethylacylfulvene) is a novel illudin S analogue that we have shown to induce caspase-mediated apoptosis in pancreatic carcinoma cell lines.
Westem blot analysis and kinase assays were used to demonstrate the activation of Erk 1/2 and JNK1 kinases following Irofulven administration in the presence and absence of selective kinase inhibitors.
Irofulven activates JNK1 and Erk1/2, but not p38. The addition of the MAPK inhibitors, SB202190 and PD98059 (targeting JNK1 and Erk1/2 activation, respectively), prevents kinase activation and blocks Irofulven-induced activation of caspases -3, -7, -8 and -9. Blockade of either JNK1 or Erk1/2 results in a 50% decrease in apoptosis in MiaPaCa-2 cells treated with Irofulven.
Our data demonstrated that JNK1 and Erk1/2 are activated by Irofulven treatment and that blockade of either MAPK subfamily decreases apoptosis by rendering Irofulven incapable of inducing caspase activation.

[Show abstract][Hide abstract] ABSTRACT: To assess the frequency and clinical features of treatment-induced bowel injury in rectal carcinoma patients receiving perioperative external beam radiotherapy (EBRT). The frequency of and factors associated with treatment-induced intestinal injury have previously not been well quantified for rectal cancer patients. Postoperative adjuvant chemoirradiation is recommended for Stage II and III rectal cancers, making such data of significant interest.
The records of 386 consecutive patients undergoing radiotherapy with or without chemotherapy (CT) for rectal carcinoma between 1981-90 were reviewed. Eight-two patients were excluded for receiving nontherapeutic EBRT or modalities other than EBRT.
Symptomatic acute treatment-related enteritis (within 30 days of EBRT +/- CT) was diagnosed in 13 patients, 3 of whom developed chronic bowel injury. Chronic treatment-related enteritis was identified in 18 patients and reoperation was required in 17 (5% of the 304 patients with complete follow-up). Chronic proctitis was documented in 38 patients, including 3 patients with small bowel injury. The probability of developing treatment-induced bowel injury at 5 years following treatment was 19%. Variables associated with an increased risk of bowel injury using multivariate analysis were transanal excision (p = 0.002), escalating radiation dose (p = 0.005), and increasing age (p = 0.01). Twenty of the affected patients required operative treatment, and 2 deaths resulted from treatment-induced enteritis.
Patients with rectal carcinoma treated with EBRT +/- CT have the risk of developing treatment-induced bowel injury. The pelvic radiation dose should be limited to < or = 5040 cGy unless small bowel can be displaced. Reperitonealization of the pelvis, or other surgical methods of excluding the small intestine should be used whenever possible.

[Show abstract][Hide abstract] ABSTRACT: Isolated pelvic recurrence of rectal carcinoma may occur in up to one third of patients following definitive resection of primary disease. The means by which recurrence is diagnosed, methods by which it may be treated, and reported outcomes are all evolving and improving. Current data indicate that a substantial proportion of patients treated by aggressive multi-modality salvage therapy may be provided with durable survival. This review highlights current concepts in the diagnosis and management of locally recurrent rectal carcinoma.
