ATM, THMS, and RRM1 protein expression in nasopharyngeal carcinomas treated with curative intent.

BACKGROUND: In advanced nasopharyngeal carcinoma (NPC), biomarkers may help predict survival. METHODS: Tumoral expression of ataxia-telangiectasia mutated (ATM), thymidylate synthetase (THMS), and ribonucleotide reductase subunit M1 (RRM1), was correlated with survival in patients with nonmetastatic NPC using quantitative fluorescence immunohistochemistry with automated quantitative digital image analysis. RESULTS: Of the 146 patients included, 58 patients (40%) received concurrent chemoradiation therapy; the remainder was treated with radiation. Overall survival (OS) at 5 years was 71% (95% confidence interval [CI], 62% to 78%); disease-free survival (DFS) was 48% (95% CI, 39% to 57%). OS worsened for increasing values of ATM (hazard ratio [HR], 2.83; 95% CI, 1.01-7.94; p = .049) for values greater than the 75th percentile compared to less than the 25th percentile, but improved for tumors with higher THMS levels (HR, 0.44; 95% CI, 0.20-0.94; p = .033) for values greater than the 25th percentile compared to less than or equal to the 25th percentile. RRM1 was not associated with OS (p = .748). No biomarkers were associated with DFS. CONCLUSION: In our cohort, relative overexpression of ATM and low THMS levels were associated with worse OS. © 2015 Wiley Periodicals, Inc. Head Neck 38: E384-E391, 2016.

Discharge to Primary Care for Survivorship Follow-Up: How Are Patients With Early-Stage Breast Cancer Faring?

PURPOSE: Oncology centers in public health systems often transfer routine follow-up of patients with early-stage breast cancer (BC) to primary care physicians because of the increasing numbers of survivors and evidence supporting the safety of this practice. After transfer of care, it is unknown how BC survivors fare with treatment and surveillance goals, and whether they have unmet needs for access to specialist care. This study conducted in a sample of women in Alberta, Canada, examined adherence with follow-up guidelines, symptoms, and need for a telephone-based survivorship clinic. METHODS: Through the Alberta Cancer Registry, we randomly invited women with stage I-III invasive BC (N=960) to participate. Of those, 272 responded, and 240 consented to a structured telephone interview and chart review. RESULTS: Women adhered well to follow-up guidelines for mammogram, but less so for clinical examination and endocrine therapy (ET). However, most patients reported ongoing bothersome symptoms, which tended to be higher in those not on ET. More than one-third of patients reported ongoing needs (managing weight, side effects, exercise adherence, and psychosocial health). Younger, fatigued or depressed, nonurban women not on ET reported the most need for a telephone clinic. CONCLUSIONS: Adherence with follow-up goals (examination, mammography, ET) was better than expected. Despite this, interest in a telephone survivorship clinic was high. Perceived needs included symptom management plus support for lifestyle behavior change. Medical follow-up needs might be well-met by discharge to primary care. However, high levels of ongoing symptoms and psychosocial needs would suggest that telephone-based survivorship clinics, psychosocial and exercise interventions, or transition programs might benefit the survivorship experience of patients with BC.
