Explainable Machine Learning Model to Predict Overall Survival in Patients Treated With Palliative Radiotherapy for Bone Metastases. JCO Clin Cancer Inform 2024; 8:e2400027. [PMID: 38917384 DOI: 10.1200/cci.24.00027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 03/18/2024] [Accepted: 04/17/2024] [Indexed: 06/27/2024] Open
Abstract
PURPOSE The estimation of prognosis and life expectancy is critical in the care of patients with advanced cancer. To aid clinical decision making, we build a prognostic strategy combining a machine learning (ML) model with explainable artificial intelligence to predict 1-year survival after palliative radiotherapy (RT) for bone metastasis. MATERIALS AND METHODS Data collected in the multicentric PRAIS trial were extracted for 574 eligible adults diagnosed with metastatic cancer. The primary end point was the overall survival (OS) at 1 year (1-year OS) after the start of RT. Candidate covariate predictors consisted of 13 clinical and tumor-related pre-RT patient characteristics, seven dosimetric and treatment-related variables, and 45 pre-RT laboratory variables. ML models were developed and internally validated using the Python package. The effectiveness of each model was evaluated in terms of discrimination. A Shapley Additive Explanations (SHAP) explainability analysis to infer the global and local feature importance and to understand the reasons for correct and misclassified predictions was performed. RESULTS The best-performing model for the classification of 1-year OS was the extreme gradient boosting algorithm, with AUC and F1-score values equal to 0.805 and 0.802, respectively. The SHAP technique revealed that higher chance of 1-year survival is associated with low values of interleukin-8, higher values of hemoglobin and lymphocyte count, and the nonuse of steroids. CONCLUSION An explainable ML approach can provide a reliable prediction of 1-year survival after RT in patients with advanced cancer. The implementation of SHAP analysis provides an intelligible explanation of individualized risk prediction, enabling oncologists to identify the best strategy for patient stratification and treatment selection.

A New Prognostic Instrument for Predicting the Probability of Completion of Cisplatin during Chemoradiation for Head and Neck Cancer. J Pers Med 2023; 13:1120. [PMID: 37511733 PMCID: PMC10381843 DOI: 10.3390/jpm13071120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 07/05/2023] [Accepted: 07/10/2023] [Indexed: 07/30/2023] Open
Abstract
Many head and neck cancer patients assigned to definitive or adjuvant chemoradiation treatment do not complete the concurrent cisplatin dose. We determined corresponding risk factors and developed a prognostic instrument to help identify these patients. Ten pre-treatment characteristics were retrospectively analyzed in 154 patients with head and neck cancer who were treated via chemoradiation with cisplatin. These pre-treatment characteristics included age, sex, Karnofsky performance score, tumor site, primary tumor stage, nodal stage, histologic grade, upfront surgery, human papilloma virus status, and history of smoking. The characteristics significantly associated with the completion of cisplatin-based treatment, the receipt of ≥80% cisplatin, or showing a strong trend of association after multivariate analyses were used for the prognostic instrument. For each characteristic, 0 points were assigned for worse outcomes, and 1 point was assigned for better outcomes. Patients' scores were calculated by adding these points. Age ≤ 60 years and a Karnofsky performance score of 90-100 were significantly associated with both endpoints after multivariate analysis, and male gender showed a trend for association with the receipt of ≥80% cisplatin. Patient scores were 0, 1, 2, and 3 points. The corresponding rates of completion of cisplatin-based treatment were 14%, 41%, 62%, and 72%, respectively (p = 0.004). The rates of receipt of ≥80% cisplatin were 29%, 54%, 72%, and 94%, respectively (p < 0.001). This new prognostic instrument helps to predict whether head and neck cancer patients scheduled for chemoradiation will receive cisplatin as planned.

Cancers (Basel) 2023; 15:3278. [PMID: 37444388 DOI: 10.3390/cancers15133278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 06/15/2023] [Accepted: 06/18/2023] [Indexed: 07/15/2023] Open
Abstract
Cisplatin is the standard for the chemoradiation of squamous cell carcinoma of the head and neck (HNSCC). Many patients cannot receive cisplatin due to impaired renal function. This study investigated carboplatin as an alternative option. In total, 131 patients assigned to two courses of cisplatin (20 mg/m2/d1--5 or 25 mg/m2/d1-4) were matched to 45 patients not suitable for cisplatin and receiving carboplatin (AUC 1.0/d1-5 or AUC 1.5/d1-4). The endpoints included loco-regional control (LRC), metastases-free survival (MFS), overall survival (OS), toxicities, and the completion of chemotherapy. The patients in the carboplatin group were significantly older and had more G3 tumors. Otherwise, the baseline characteristics were balanced. The LRC rates at 2 and 3 years were 77% and 76% in the cisplatin group vs. 69% and 65% in the carboplatin group (p = 0.21). The MFS rates were 83% and 78% vs. 78% and 74% (p = 0.34) and the OS rates 83% and 79% vs. 83% and 75% (p = 0.64), respectively. The outcomes were not significantly different in the subgroups receiving definitive or adjuvant chemoradiation. No significant differences were found regarding toxicities. Non-significantly more patients in the carboplatin group completed their chemotherapy (78% vs. 66%, p = 0.15). Carboplatin was associated with similar outcomes and toxicities as cisplatin, although these patients had worse renal function, more aggressive tumors, and were older. Given the limitations of this study, carboplatin appears an option for patients not suitable for cisplatin.

First Results of Concurrent Chemoradiation with Two Courses of 5 × 25 mg/m 2 Cisplatin for Locally Advanced Head and Neck Cancer. J Pers Med 2023; 13:1006. [PMID: 37373994 DOI: 10.3390/jpm13061006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 06/15/2023] [Accepted: 06/15/2023] [Indexed: 06/29/2023] Open
Abstract
Many patients with squamous cell carcinoma of the head and neck (SCCHN) receive cisplatin-based chemoradiation. Cisplatin 100 mg/m2 every three weeks is toxic and alternative cisplatin regimens are desired. Two courses of 20 mg/m2/day 1-5 (cumulative 200 mg/m2) were shown to be similarly effective and better tolerated than 100 mg/m2 every three weeks. Previous studies suggested that cumulative doses >200 mg/m2 may further improve outcomes. In this study, 10 patients (group A) receiving two courses of 25 mg/m2/day 1-5 (cumulative 250 mg/m2) in 2022 were retrospectively matched and compared to 98 patients (group B) receiving two courses of 20 mg/m2/day 1-5 or 25 mg/m2/day 1-4 (cumulative 200 mg/m2). Follow-up was limited to 12 months to avoid bias. Group A achieved non-significantly better 12-month loco-regional control (100% vs. 83%, p = 0.27) and metastases-free survival (100% vs. 88%, p = 0.38), and similar overall survival (89% vs. 88%, p = 0.90). No significant differences were found regarding toxicities, completion of chemotherapy, and interruption of radiotherapy. Given the limitations of this study, chemoradiation with two courses of 25 mg/m2/day 1-5 appears an option for carefully selected patients as a personalized treatment approach. Longer follow-up and a larger sample size are needed to properly define its role.

Abstract
Importance Combined modality therapy, such as chemoradiotherapy, often results in significant morbidity among patients with head and neck cancer. Although the role of body mass index (BMI) varies based on cancer subtypes, its association with treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer remains unclear. Objective To evaluate the role of BMI in treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer undergoing chemoradiotherapy. Design, Setting, and Participants This retrospective, observational, single-institution cohort study conducted at a comprehensive cancer center included 445 patients with nonmetastatic head and neck cancer who underwent chemoradiotherapy from January 1, 2005, to January 31, 2021. Exposure Normal vs overweight or obese BMI. Main Outcomes and Measures Metabolic response after chemoradiotherapy, locoregional failure (LRF), distant failure (DF), overall survival (OS), and progression-free survival (PFS), with Bonferroni correction used to adjust for multiple comparisons and P < .025 being considered statistically significant. Results A total of 445 patients (373 men [83.8%]; median age, 61 years [IQR, 55-66 years]; 107 [24.0%] with normal BMI, 179 [40.2%] with overweight BMI, and 159 [35.7%] with obese BMI) were included for analysis. Median follow-up was 48.1 months (IQR, 24.7-74.9 months). On Cox proportional hazards regression multivariable analysis, only overweight BMI was associated with improved OS (5-year OS, 71.5% vs 58.4%; adjusted hazard ratio [AHR], 0.59 [95% CI, 0.39-0.91]; P = .02) and PFS (5-year PFS, 68.3% vs 50.8%; AHR, 0.51 [95% CI, 0.34-0.75]; P < .001). On logistic multivariable analysis, overweight BMI (91.6% vs 73.8%; adjusted odds ratio [AOR], 0.86 [95% CI, 0.80-0.93]; P < .001) and obese BMI (90.6% vs 73.8%; AOR, 0.89 [95% CI, 0.81-0.96]; P = .005) were associated with complete metabolic response on follow-up positron emission tomography-computed tomography after treatments. On Fine-Gray multivariable analysis, overweight BMI was associated with reduction in LRF (5-year LRF, 7.0% vs 25.9%; AHR, 0.30 [95% CI, 0.12-0.71]; P = .01), but not DF (5-year DF, 17.4% vs 21.5%; AHR, 0.92 [95% CI, 0.47-1.77]; P = .79). Obese BMI was not associated with LRF (5-year LRF, 10.4% vs 25.9%; AHR, 0.63 [95% CI, 0.29-1.37]; P = .24) or DF (5-year DF, 15.0% vs 21.5%; AHR, 0.70 [95% CI, 0.35-1.38]; P = .30). Conclusion In this cohort study of patients with head and neck cancer, when compared with normal BMI, overweight BMI was an independent factor favorably associated with complete response after treatments, OS, PFS, and LRF. Further investigations are warranted to improve understanding on the role of BMI among patients with head and neck cancer.

Abstract
PURPOSE There is an unmet need to empirically explore and understand drivers of cancer disparities, particularly social determinants of health. We explored natural language processing methods to automatically and empirically extract clinical documentation of social contexts and needs that may underlie disparities. METHODS This was a retrospective analysis of 230,325 clinical notes from 5,285 patients treated with radiotherapy from 2007 to 2019. We compared linguistic features among White versus non-White, low-income insurance versus other insurance, and male versus female patients' notes. Log odds ratios with an informative Dirichlet prior were calculated to compare words over-represented in each group. A variational autoencoder topic model was applied, and topic probability was compared between groups. The presence of machine-learnable bias was explored by developing statistical and neural demographic group classifiers. RESULTS Terms associated with varied social contexts and needs were identified for all demographic group comparisons. For example, notes of non-White and low-income insurance patients were over-represented with terms associated with housing and transportation, whereas notes of White and other insurance patients were over-represented with terms related to physical activity. Topic models identified a social history topic, and topic probability varied significantly between the demographic group comparisons. Classification models performed poorly at classifying notes of non-White and low-income insurance patients (F1 of 0.30 and 0.23, respectively). CONCLUSION Exploration of linguistic differences in clinical notes between patients of different race/ethnicity, insurance status, and sex identified social contexts and needs in patients with cancer and revealed high-level differences in notes. Future work is needed to validate whether these findings may play a role in cancer disparities.

Impact of a mobile application (reminder app) on acute toxicity during radiotherapy of head-and-neck cancer – results of a randomized phase III trial (RAREST-02). BMC Cancer 2022; 22:989.

Abstract
Abstract
Background
Radiotherapy of head-and-neck cancer (SCCHN) is often associated with acute toxicity. In a previous trial, daily reminders by staff members to perform skin care resulted in less dermatitis. This randomized trial investigated whether a mobile application can replace these reminders.
Methods
Patients were stratified according to tumor site, treatment and center. Fifty-three patients were eligible for per-protocol-set (25 with, 28 without app). Primary endpoint was grade ≥ 2 dermatitis until 60 Gy. Secondary endpoints included dermatitis grade ≥ 2 until end of radiotherapy (EOT), dermatitis grade ≥ 3, and mucositis grade ≥ 2 and ≥ 3.
Results
After an interim analysis, the study was terminated (delayed and slow accrual). Until 60 Gy, grade ≥ 2 dermatitis rates were 72% with vs. 82% without app (p = 0.38), grade ≥ 3 dermatitis rates 20% vs. 11% (p = 0.45). Until EOT, grade ≥ 2 and ≥ 3 dermatitis rates were 72% vs. 86% (p = 0.22) and 24% vs. 18% (p = 0.58). Until 60 Gy, grade ≥ 2 and ≥ 3 mucositis rates were 76% vs. 82% (p = 0.58) and 20% vs. 36% (p = 0.20). Until EOT, corresponding mucositis rates were 76% vs. 82% (p = 0.58) and 28% vs. 43% (p = 0.26).
Conclusion
Given the limitations of this trial, the reminder app led to non-significant reduction of grade ≥ 2 dermatitis, grade ≥ 2 mucositis and ≥ 3 mucositis. Additional studies are required to define the value of reminder apps during radiotherapy for SCCHN.

Abstract
Abstract
Background
To analyze clinical characteristics in the prediction of death within 1 year in advanced oropharyngeal cancer patients treated with chemoradiation.
Methods
One hundred forty-seven advanced oropharyngeal cancer patients who underwent curative-intent chemoradiation treatment were retrospectively enrolled. The pre-treatment clinical parameters including inflammatory markers were reviewed.
Results
The 1-year death rate for all patients was 29% [95% confidence interval (CI): 23–37%]. In multivariate logistic regression analysis, hemoglobulin (Hb) < 13.5 g/dl was an independent indicator of death within 1-year [Odds ratio (OR) 5.85, 95% CI 2.17–15.75, p < 0.001]. Systemic immune inflammation (SII) ≥ 1820 was also a significant factor for prediction of death within 1 year (OR 4.78, 95% CI 1.44–15.85, p = 0.011). We further used gander, age, Hb and SII to develop a nomogram to predict death within 1 year. The c-index of the model was 0.75 (95%CI 0.66–0.83). For patients with low nomogram score (< 14) versus high nomogram score (≥ 14), the 1-year and 2-year OS rates were 91 and 71% versus 53 and 29%, respectively. (p < 0.001). A difference in the disease persistence or recurrence rate between patients with high and low nomogram score was significant (73 and 28%, respectively; p < 0.001).
Conclusions
The pre-treatment Hb < 13.5 g/dl and SII ≥ 1820 are associated with higher risks of death within 1-year in patients with advanced oropharyngeal cancers. Nomogram can aid in patient counseling and treatment modality adjustment. The development of a more effective treatment protocol for patients with high nomogram score will be essential.

[PMID: 34595104 PMCID: PMC8476902 DOI: 10.3389/fonc.2021.648637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Accepted: 08/25/2021] [Indexed: 12/08/2022] Open
Abstract
Purpose Radiotherapy is the most important primary treatment for patients with nasopharyngeal carcinoma. Generally, the treatment duration of radiotherapy takes six or six and half weeks with 30 to 33 fractions. The current study was conducted to evaluate the association between prognosis and the duration of radiotherapy in nasopharyngeal carcinoma patients. Methods Patients with primary nasopharyngeal carcinoma who were treated with intensity-modulated radiotherapy and concurrent cisplatin-based chemotherapy, with or without induction chemotherapy between January, 2008 and December, 2013 at a single institution were retrospectively reviewed. Results In total, 1292 patients were included. At a median follow-up of 71.0 months (range 2.0–126.0 months), locoregional recurrence, distant failure and death were observed in 8.8%, 12.2% and 15.6% of all patients, respectively. Estimated 5-year locoregional relapse–free survival, distant metastasis–free survival, progression-free survival and overall survival in patients with radiation ≤ 7 weeks versus patients with radiation >7 weeks were: 93.2% versus 87.0% (P < 0.001), 89.4% versus 84.4% (P = 0.016), 79.8% versus 70.6% (P < 0.001) and 87.2% versus 78.4% (P < 0.001), respectively. Conclusions Prolonged duration of radiotherapy with a significantly higher risk of distant metastasis and death in nasopharyngeal carcinoma patients. Understanding this point, healthcare providers should make efforts to avoid prolonged duration of radiotherapy to minimize the risk of treatment failure.

CANCER DIAGNOSIS & PROGNOSIS 2021; 1:165-172. [PMID: 35399304 PMCID: PMC8962797 DOI: 10.21873/cdp.10022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Accepted: 07/05/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND The standard irradiation dose to the elective lymph node area (ELNA) in locally patients with advanced head and neck squamous cell carcinoma (LA-HNSCC) to control lymph node micrometastases (LN-MM) has not changed since it was empirically determined in the 1950s. We investigated the optimal irradiation dose for controlling LN-MM in ELNAs. PATIENTS AND METHODS The pattern of recurrence of LA-HNSCC was retrospectively evaluated in patients who underwent concurrent chemoradiotherapy with cisplatin or radiation therapy alone. RESULTS In total, 162 patients were enrolled. The median observation period was 34 months. No recurrence was found in ELNAs. After propensity score matching, a cisplatin dose of ≥200 mg/m 2 yielded a significantly higher overall survival rate (p≤0.001) and locoregional control rate (p=0.034) than did a dose of <100 mg/m 2 . CONCLUSION CCRT with a cisplatin dose of ≥200 mg/m 2 can reduce the irradiation dose to 40-44 Gy at 2 Gy per fraction to control LN-MM.

Abstract
Aim Evaluate pretreatment hemoglobin values as a prognostic factor in patients with locally advanced head and neck squamous cell carcinoma treated with concurrent chemoradiotherapy. Background Anemia is one of the most prevalent laboratory abnormalities in oncological disease. It leads to a decrease in cellular oxygen supply, altering radiosensitivity of tumor cells and compromising therapeutic outcomes. Materials and Methods Retrospective evaluation of patients with HNSCC treated with cCRT. Primary and secondary endpoint was to evaluate the correlation of Hb levels (≥12.5 g/dL or <12.5 g/dL) at the beginning of cCRT with overall survival (OS) and progression-free survival (PFS), respectively. Results A total of 108 patients were identified. With a median follow-up of 16.10 months median OS was 59.70 months for Hb ≥12.5 g/dL vs. 14.13 months for Hb <12.5 g/dL (p = 0.004). PFS was 12.29 months for Hb ≥12.5 g/dL and 1.68 months for Hb <12.5 g/dL (p = 0.016). Conclusions In this analysis, Hb ≥12.5 g/dL correlated with significantly better OS and PFS. Further studies are needed to validate these findings.

Abstract
Purpose To investigate the efficacy and toxicity of cetuximab when added to radiochemotherapy for unresectable esophageal cancer. Methods This randomized phase 2 trial (clinicaltrials.gov, identifier NCT01787006) compared radiochemotherapy plus cetuximab (arm A) to radiochemotherapy (arm B) for unresectable esophageal cancer. Primary objective was 2‑year overall survival (OS). Arm A was considered insufficiently active if 2‑year OS was ≤40% (null hypothesis = H0), and promising if the lower limit of the 95% confidence interval was >45%. If that lower limit was >40%, H0 was rejected. Secondary objectives included progression-free survival (PFS), locoregional control (LC), metastases-free survival (MFS), response, and toxicity. The study was terminated early after 74 patients; 68 patients were evaluable. Results Two-year OS was 71% in arm A (95% CI: 55–87%) vs. 53% in arm B (95% CI: 36–71%); H0 was rejected. Median OS was 49.1 vs. 24.1 months (p = 0.147). Hazard ratio (HR) for death was 0.60 (95% CI: 0.30–1.21). At 2 years, PFS was 56% vs. 44%, LC 84% vs. 72%, and MFS 74% vs. 54%. HRs were 0.51 (0.25–1.04) for progression, 0.43 (0.13–1.40) for locoregional failure, and 0.43 (0.17–1.05) for distant metastasis. Overall response was 81% vs. 69% (p = 0.262). Twenty-six and 27 patients, respectively, experienced at least one toxicity grade ≥3 (p = 0.573). A significant difference was found for grade ≥3 allergic reactions (12.5% vs. 0%, p = 0.044). Conclusion Given the limitations of this trial, radiochemotherapy plus cetuximab was feasible. There was a trend towards improved PFS and MFS. Larger studies are required to better define the role of cetuximab for unresectable esophageal cancer.

Radiotherapy-related skin toxicity (RAREST-02): A randomized trial testing the effect of a mobile application reminding head-and-neck cancer patients to perform skin care (reminder app) on radiation dermatitis. Trials 2020; 21:424. [PMID: 32450921 PMCID: PMC7249413 DOI: 10.1186/s13063-020-04307-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Accepted: 04/02/2020] [Indexed: 11/10/2022] Open
Abstract
Background Radiotherapy of head-and-neck cancer can be associated with significant toxicities including dermatitis and oral mucositis. Severe toxicities may require interruptions of the radiation treatment associated with impairment of the patients’ prognoses. This study will investigate whether the addition of a reminder app to standard care can reduce dermatitis and oral mucositis rates during radiotherapy in these patients. Methods This randomized trial compares standard care supported by a reminder app (Arm A) to standard care alone (Arm B) with respect to grade ≥ 2 radiation dermatitis and oral mucositis at 60 Gy of radiotherapy, the minimum planned dose for patients receiving definitive or adjuvant radiotherapy for locally advanced head- and-neck cancer. Moreover, radiation-induced dermatitis and oral mucositis grade ≥ 3 at 60 Gy and both grade ≥ 2 and grade ≥ 3 at the end of radiation treatment (EOT) will be evaluated, as well as quality of life and pain. According to sample size calculations, 80 patients are required per arm within the full analysis set. Taking into account that 5% of patients will not qualify for full analysis set, 168 patients should be randomized. The impact of the reminder app will be considered clinically relevant, if the rates of grade ≥ 2 radiation dermatitis (primary endpoint) and oral mucositis (secondary endpoint) can be reduced by 20%. Discussion If the addition of a reminder app to standard care will lead to a significant reduction of radiation dermatitis and oral mucositis, it could become a helpful tool for patients with head-and-neck cancer during radiotherapy. Trial registration clinicaltrials.gov (NCT04110977). Registered on September 27, 2019. First patient is planned to be included in December 2019.

Abstract
Anemia has been identified as a significant negative prognosticator in head and neck squamous cell carcinoma (HNSCC) concurrent chemoradiotherapy (CCRT). Irrespective of the causes, anemia in HNSCC is believed to contribute to intratumoral hypoxia, which reduces the effectiveness of radiotherapy and oxygen-dependent chemotherapy. Correction of anemia with recombinant human erythropoietin (rHu-EPO) has been performed as a surrogate for hypoxia compensation to improve tumor control and survival outcomes. However, the results of the most important EPO clinical trials have been disappointing. Following the recent finding that EPO and its receptor (EPOR) are both expressed in HNSCC specimens, a new hypothesis has been advanced. This postulates that hypoxic signaling might activate EPOR through the hypoxia-inducible factor (HIF) signaling pathway and its downstream effectors, including carbonic anhydrase 9 (CA-9), glucose transporter 1 (GLUT-1), and vascular endothelial growth factor (VEGF), leading to the failure of rHu-EPO treatment, as assessed from the results of the best-known EPO trials. This review addresses the relationship among anemia, hypoxia, and tumoral EPO/EPOR expression in HNSCC treatment in an attempt to elucidate the main mechanisms involved in the resistance to rHu-EPO therapy, as in a carousel.

Abstract
BACKGROUND To retrospectively investigate the influence of pretreatment anemia and hemoglobin levels on the survival of nasopharyngeal carcinoma patients treated with concurrent chemoradiotherapy (C-CRT). METHODS A total of 149 nasopharyngeal carcinoma patients who received C-CRT were included. All patients had received 70 Gy to the primary tumor plus the involved lymph nodes, and 59.4 Gy and 54 Gy to the intermediate- and low-risk neck regions concurrent with 1-3 cycles of cisplatin. Patients were dichotomized into non-anemic and anemic (hemoglobin <12 g/dL (women) or <13 g/dL (men)) groups according to their pre-treatment hemoglobin measures. Receiver operating characteristic (ROC) curve analysis was utilized for accessibility of a pre-treatment hemoglobin cut-off that impacts outcomes. Potential interactions between baseline anemia status and hemoglobin measures and overall survival, locoregional progression-free survival (LRPFS), and progression-free survival were assessed. RESULTS Anemia was evident in 36 patients (24.1%), which was related to significantly shorter overall survival (P=0.007), LRPFS (P<0.021), and progression-free survival (P=0.003) times; all three endpoints retained significance in multivariate analyses (P<0.05, for each). A baseline hemoglobin value of 11.0 g/dL exhibited significant association with outcomes in ROC curve analysis: hemoglobin <11.0 g/dL (N=26) was linked with shorter median overall survival (P<0.001), LRPFS (P=0.004), and progression-free survival (P<0.001) times, which also retained significance for all three endpoints in multivariate analyses and suggested a stronger prognostic worth for the hemoglobin <11.0 g/dL cut-off value than the anemia status. CONCLUSION Pre-C-CRT hemoglobin <11.0 g/dL has a stronger prognostic worth than the anemia status with regard to LRPFS, progression-free survival, and overall survival for nasopharyngeal carcinoma patients.

Abstract
OBJECTIVE Patients with head and neck cancer (HNC) can die of index tumor progression and second tumor or non-cancer causes. Here, we investigated the risk factors for competing non-cancer mortality (NCM) in a prospective cohort of patients with advanced-stage HNC. MATERIALS AND METHODS A prospective observational study was conducted with 604 patients who underwent definitive treatment for advanced-stage HNC between 2010 and 2015. Main outcomes were NCM and cancer mortality (CM) defined as death from non-cancer causes and HNC or second cancers, respectively. Cumulative incidence and cause-specific hazard functions were used to analyze the risk factors of NCM and CM. RESULTS Age, smoking, Charlson comorbidity index (CCI), performance status, body mass index, rural residence, education and hemoglobin level at diagnosis, and chemotherapy were significantly associated with NCM (all p < 0.05). Multivariate analyses showed that age, CCI, and hemoglobin were independent factors of NCM. Age (≥65 years), CCI (≥2), and hemoglobin (<11 g/dl) were related to 4.5-, 3.2-, and 2.7-fold increased adjusted risk of NCM, respectively. CONCLUSIONS Old age, comorbidity, and hemoglobin at diagnosis were independent predictors of NCM. The risk factors could be used to predict non-cancer death after definitive treatment for advanced-stage HNC.

Abstract
Background The aim of the present trial is to investigate a new option of skin protection in order to reduce the rate of grade ≥ 2 skin toxicity in patients receiving radiotherapy alone or radiochemotherapy for locally advanced squamous cell carcinoma of the head-and-neck (SCCHN). Methods / Design This is a randomized, active-controlled, parallel-group multi-center trial that compares the following treatments of radiation dermatitis in patients with head-and-neck cancer: Mepitel® Film (Arm A) vs. standard care (Arm B). The primary aim of this trial is to investigate the rate of patients experiencing grade ≥ 2 radiation dermatitis (according to Common Toxicity Criteria for Adverse Events (CTCAE) Version 4.03) until 50 Gy of radiotherapy. Evaluation until 50 Gy of radiotherapy has been selected as the primary endpoint, since up to 50 Gy, the irradiated volume includes the primary tumor and the bilateral cervical and supraclavicular lymph nodes, and, therefore, is similar in all patients. After 50 Gy, irradiated volumes are very individual, depending on location and size of the primary tumor, involvement of lymph nodes, and the treatment approach (definitive vs. adjuvant). In addition, the following endpoints will be evaluated: Time to grade 2 radiation dermatitis until 50 Gy of radiotherapy, rate of patients experiencing grade ≥ 2 radiation dermatitis during radio(chemo)therapy, rate of patients experiencing grade ≥ 3 skin toxicity during radio(chemo)therapy, adverse events, quality of life, and dermatitis-related pain. Administration of Mepitel® Film will be considered to be clinically relevant, if the rate of grade ≥ 2 radiation dermatitis can be reduced from 85% to 65%. Discussion If administration of Mepitel® Film instead of standard care will be able to significantly reduce the rate of grade ≥ 2 radiation dermatitis, it could become the new standard of skin care in patients irradiated for SCCHN. Trial registration clinicaltrials.gov NCT03047174. Registered on 26th of January, 2017. First patient included on 9th of May, 2017.

Abstract
OBJECTIVE In our previous work, we incorporated complete blood count (CBC) into TNM stage to develop a new prognostic score model, which was validated to improve prediction efficiency of TNM stage for nasopharyngeal carcinoma (NPC). The purpose of this study was to revalidate the accuracy of the model, and its superiority to TNM stage, through data from a prospective study. METHODS CBC of 249 eligible patients from the 863 Program No. 2006AA02Z4B4 was evaluated. Prognostic index (PI) of each patient was calculated according to the score model. Then they were divided by the PI into three categories: the low-, intermediate-and high-risk patients. The 5-year disease-specific survival (DSS) of the three categories was compared by a log-rank test. The model and TNM stage (7th edition) were compared on efficiency for predicting the 5-year DSS, through comparison of the area under curve (AUC) of their receiver-operating characteristic curves. RESULTS The 5-year DSS of the low-, intermediate-and high-risk patients were 96.0%, 79.1% and 62.2%, respectively. The low-and intermediate-risk patients had better DSS than the high-risk patients (P<0.001 and P<0.005, respectively). And there was a trend of better DSS in the low-risk patients, compared with the intermediate-risk patients (P=0.049). The AUC of the model was larger than that of TNM stage (0.726 vs. 0.661, P=0.023). CONCLUSIONS A CBC-based prognostic score model was revalidated to be accurate and superior to TNM stage on predicting 5-year DSS of NPC.

Abstract
PURPOSE We aim to identify the risk factors for a "rocky" treatment course (RTC) in head and neck cancer. METHODS A retrospective case-control study was conducted utilizing data from a prospective study. We defined the RTC as a composite of adverse outcomes including G-tube dependence and increased nursing interventions. Statistically associative variables were included in a multivariable logistic regression. We also evaluated whether the RTC, or its components, associated with worse cancer outcomes. RESULTS Being single, unemployed, having N2/3 disease and receiving chemoradiotherapy were associated with a RTC. In turn, G-tube dependence was associated with worse 3-year OS (73 vs 91 %; p = 0.02) and increased nursing interventions with worse 3-year locoregional recurrence-free survival (LRFS) (85 vs 92 %; p = 0.03) and locoregional recurrence (LRR) (14 vs 7 %; p = 0.03). CONCLUSIONS We identified baseline factors associated with a RTC for head and neck cancer patients. Future supportive care interventions could be evaluated using the RTC as a marker of benefit.

Abstract
Many patients with locally advanced squamous cell carcinoma of the head and neck (LASCCHN) receive cisplatin-based radiochemotherapy. The optimal regimen is still unclear when considering both efficacy and feasibility. This study compared two regimens for locoregional control (LRC), overall survival (OS), and adverse events. Data of 329 patients with LASCCHN receiving definitive or postoperative radiochemotherapy were retrospectively analyzed. A total of 131 patients received 100 mg/m(2) cisplatin on days 1, 22, and 43 (group A), and 198 patients received 20 mg/m(2) cisplatin plus 600/1000 mg/m(2) 5-FU on days 1-5 and days 29-33 (group B). Radiochemotherapy regimens plus nine factors were compared for LRC and OS, and radiochemotherapy regimens additionally for adverse events. On univariate analysis, chemotherapy type was not associated with LRC (p = 0.36). On multivariate analysis, performance score (p = 0.039), N-category (p = 0.007), histologic grade (p = 0.007), upfront surgery (p = 0.030), and pre-radiochemotherapy hemoglobin levels (p < 0.001) were associated with LRC. On univariate analysis, chemotherapy type had no impact on OS (p = 0.64). On multivariate analysis, performance score (p < 0.001), T-category (p = 0.025), N-category (p < 0.001), histologic grade, and hemoglobin levels (p < 0.001) were associated with OS. Renal failure occurred significantly more often in group A (p = 0.008). Otherwise, adverse events were not significantly different. Thus, both radiochemotherapy regimens appeared similarly effective for LASCCHN. Patients receiving 100 mg/m(2) of cisplatin require close monitoring of their renal function.

The Impact of the Overall Radiotherapy Time on Clinical Outcome of Patients with Nasopharyngeal Carcinoma; A Retrospective Study. PLoS One 2016; 11:e0151899.

Abstract
Purpose In Yogyakarta, nasopharyngeal carcinoma (NPC) shows a poor response to radiotherapy treatment. Previous study showed a prolonged overall treatment time (OTT), due to interruptions during treatment. This study explores the association between clinical outcome and OTT. Secondary, the relation between clinical outcome and disease stage, waiting time to radiation (WT) and chemotherapy schedule was explored. Methods In this retrospective cohort, 142 patients who started curative intent radiotherapy for NPC between March 2009 and May 2014, with or without chemotherapy, were included. The median follow up time was 1.9 years. Data was collected on WT, OTT, disease stage, and chemotherapy schedule. Time factors were log-transformed. Clinical outcome was defined as therapy response, loco-regional control (LRC), disease free survival (DFS) and overall survival (OS). Results The median WT was 117 days (range 12–581) and OTT was 58 days (43–142). OTT and disease stage were not associated to any of the clinical outcome parameters. The log- WT was associated to poor therapy outcome (HR 1.68; 95% ci: 1.09–2.61), LRC (HR 1.66; 95% ci: 1.15–2.39), and DFS (HR 1.4; 95% ci: 1.09–1.81). In the multivariable analysis, significant hazard risk for poor therapy response, LRC, DFS and OS were seen for patients who didn’t received concurrent chemotherapy. Conclusion Not receiving concurrent chemotherapy showed the strongest risk for poor outcome. Since the choice of chemotherapy is related to a variety of factors, like the WT and patient’s physical condition when radiation can start, careful interpretation is needed. Reason for not finding a relation between OTT and clinical outcome might be the low number of patients who finished radiotherapy within 7 weeks, or by a stronger detrimental effect of other factors.

Abstract
AIM: To investigate whether selenomethionine (SLM) reduces mucositis incidence in patients with head and neck squamous cell cancer (HNSCC) undergoing concurrent chemoradiation (CRT).
METHODS: In this multi-institutional, randomized, double-blind phase II trial, patients with Stage III or IV HNSCC received SLM 3600 μg/m2 or placebo twice daily for 7 d prior to CRT, once daily during CRT, and daily for 3 wk following CRT. CRT consisted of 70 Gy at 2 Gy per fraction with cisplatin 100 mg/m2 IV on days 1, 22, and 43.
RESULTS: Eighteen patients were randomized, 10 received SLM, and there were no differences in baseline factors. There was no difference in mucositis or patient-reported side effects between groups. There was no difference in overall or relapse-free survival at 12 mo.
CONCLUSION: Addition of SLM to CRT for HNSCC was well-tolerated but did not lower the incidence of severe mucositis or improve quality of life or survival outcomes.

Abstract
Due to the low incidence of pretreatment anemia in nasopharyngeal carcinoma (NPC), the true prognostic impact of pretreatment anemia may be underestimated before. We retrospectively analyzed the association of pretreatment anemia with disease-specific survival (DSS), distant-metastasis-free survival (DMFS), and locoregional-relapse-free survival (LRFS) by Cox regression in a cohort of 5830 patients, stratifying by midtreatment anemia, smoking, body mass index (BMI), etc. Pretreatment anemia was significantly associated with adverse DSS (hazard ratio (HR) = 2.15, 95 % confidence interval (CI) 1.62-2.85, P < 0.001) and DMFS (HR = 1.53, 95 % CI 1.08-2.17, P = 0.018), comparing to patients with normal hemoglobin, after adjusting for covariates. Moreover, the association with DSS remained unchanged regardless of smoking status and clinical stage, whereas it was limited in the subgroups of above 45 years, male sex, and BMI <25 kg/m(2). With restriction to midtreatment anemic patients, pretreatment anemia was still strongly correlated with inferior DSS and DMFS. This study, in the largest reported cohort, is the first to show the adverse prognostic impact of pretreatment anemia on DSS and DMFS in NPC.

Abstract
Purpose: To investigate prognostic impact of chemoradiotherapy-induced hemoglobin (Hb) decrease on treatment outcomes of endemic nasopharyngeal carcinoma (NPC). Materials and Methods: Eight hundred and fifteen non-metastatic NPC, receiving neoadjuvant chemotherapy followed by radiotherapy (NACT+RT group) or concomitant chemoradiotherapy (CCRT group), were enrolled in this study, who were regrouped according to pre-radiotherapy Hb (pre-RT Hb), post-radiotherapy Hb (post-RT Hb) and individual Hb decrease through radiotherapy or CCRT (△Hb), respectively. Survival curves were estimated using Kaplan-Meier method and compared by log-rank test. Multivariate analysis was performed using the COX proportional hazard model and binary logistic regression model. Results: A poorer 5-year disease-free survival (DFS) was observed when pre-RT Hb<130.00 g/L. However, post-RT Hb<130.00 g/L was associated with significantly poorer 5-year locoregional recurrence-free survival (LRFS) (P=0.010) and disease specific survival (DSS) (P=0.008). Multivariate analysis with the COX proportional hazard model identified post-RT Hb<130.00 g/L as an independent negative prognostic factor for both LRFS (hazard ratio [HR], 1.896; 95% confidence interval [CI], 1.158-3.106; P=0.011) and DSS (HR, 1.767; 95% CI, 1.152-2.711; P=0.009). Similarly, △Hb <-15.00 g/L also predicted poorer 5-year LRFS (P=0.024) and DSS (P=0.015), which was confirmed in multivariate analysis as an independent adverse prognostic factor for LRFS (HR, 1.586; 95% CI, 1.058-2.377; P=0.026) and DSS (HR, 1.556; 95% CI, 1.087-2.227; P=0.016), respectively. Multivariate analysis with binary logistic regression model indicated that CCRT was a significantly independent predictor for post-RT Hb <130.00 g/L and △Hb < -15.00 g/L. Conclusions: Chemoradiotherapy-induced decreased Hb levels have negative influence on locoregional control and survival, and might counteract the benefit of neoadjuvant/concomitant chemotherapy. Further studies on supportive care to maintain sufficient Hb level during chemo-radiotherapy are warranted.

Abstract
The reporting of infection/sepsis in chemo/radiation-treated head and neck cancer patients is sparse and the problem is underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met with the aim of reaching a consensus on a clinical definition and management of infections and sepsis. The Delphi appropriateness method was used for this consensus. External expert reviewers then evaluated the conclusions carefully according to their area of expertise. The paper contains seven clusters of statements about the clinical definition and management of infections and sepsis in head and neck cancer patients, which had a consensus. Furthermore, it offers a review of recent literature in these topics.

Abstract
Background This study investigated the prognostic role of nuclear expression of p65 in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) receiving post-operative radio(chemo)therapy. Methods Nuclear p65-expression (H-score ≤50 versus >50) plus twelve characteristics were analyzed in 151 patients for overall survival (OS), metastases-free survival (MFS) and loco-regional control (LRC). Additional characteristics included age, gender, Karnofsky performance score (KPS), pre-radiotherapy hemoglobin levels, tumor site, histological grading, human papilloma virus (HPV)-status, T-classification, N-classification, American Joint Committee on Cancer (AJCC)-stage, extent of resection and concurrent chemotherapy. Univariate analyses were performed with Kaplan-Meier method and log-rank test, multivariate analyses with Cox proportional hazards model. Results On univariate analyses, p65-expression had a significant impact on OS (p < 0.001) and LRC (p < 0.001) but not on MFS (p = 0.29). On multivariate analysis, KPS ≥80 (risk ratio [RR] 2.23; p = 0.012), HPV-positivity (RR 5.83; p = 0.020), T1-T2 (RR 1.38; p = 0.048), N0-N2a (RR 2.72; p = 0.005) and complete resection (RR 2.02; p = 0.049) were positively associated with OS; p65-negativity achieved borderline significance (RR 3.02; p = 0.052). Better MFS was associated with KPS ≥80 (RR 2.49; p = 0.015), T1-T2 (RR: 1.74; p = 0.005), N0-N2a (RR: 6.22; p < 0.001) and complete resection (RR 3.43; p = 0.003). Positive associations with LRC were found for p65-negativity (RR 5.06; p = 0.008), T1-T2 (RR: 1.49; p = 0.022), N0-N2a (RR: 2.97; p = 0.004) and favorable tumor site (RR 1.28; p = 0.025). Conclusions P65-negativity was significantly associated with improved LRC and achieved borderline significance with respect to improved OS. Thus, p65-expression may be an additional target for novel agents in the treatment of locally advanced SCCHN.

Abstract
BACKGROUND Anemia, a common complication of head and neck cancer treatment, is regarded as a poor prognostic factor. We evaluated the impact of low hemoglobin (Hb) levels, measured at different time points, on a consecutive cohort of patients with locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN) who underwent postoperative concurrent chemoradiotherapy (CCRT). MATERIALS AND METHODS From 2002 to 2009, 140 patients were enrolled and reviewed retrospectively. Preoperative (pre-op Hb), pre-CCRT Hb, and nadir Hb during CCRT were measured and recorded. The three Hb parameters were analyzed against several well-established pathologic risk factors and radiation-associated variables. Prognostic impacts were investigated with multivariate analysis by Cox proportional hazards model. RESULTS On Cox regression analysis, significantly higher risk of death was associated with pre-op Hb ≦13 g/dL (hazard ratio [HR] =1.8; 95% confidence interval [CI], 1.1-3.1; P=0.023), nadir Hb ≦11 g/dL (HR =1.9; 95% CI, 1.1-3.3; P=0.020), radiation treatment time (RTT) >7 weeks (HR =1.9; 95% CI, 1.1-3.3; P=0.022), and multiple positive lymph nodes (HR =2.1; 95% CI, 1.2-3.7; P=0.010), after adjusting for primary tumor site and pathologic lymphovascular invasion. Patients with poor prognosticators including low nadir Hb ≦11 g/dL and RTT >7 weeks had a higher risk of death (HR =4.0; 95% CI =1.6-10.2; P=0.004). CONCLUSION In the treatment setting of LA-SCCHN patients who underwent postoperative CCRT, coexistance of lower nadir Hb during CCRT and prolonged RTT resulted in reduced survival.

Abstract
BACKGROUND AND PURPOSE To investigate the potential prognostic role of tumor cell podoplanin expression in patients treated with resection followed by irradiation or chemoradiotherapy for locally advanced squamous cell carcinoma of the head and neck (SCCHN). MATERIALS AND METHODS Podoplanin expression (≤10 % versus > 10 %) and 12 other factors were evaluated in 160 patients for their association with locoregional control (LRC), metastases-free (MFS) and overall survival (OS). Other factors were age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, preradiotherapy (pre-RT) hemoglobin level, tumor site, histological grading, T category, N category, American Joint Committee on Cancer (AJCC) stage, human papillomavirus (HPV) status, extent of resection and concurrent chemotherapy. RESULTS In multivariate analysis, ECOG performance status 0-1 (risk ratio, RR: 3.01; 95 % confidence interval, CI: 1.42-7.14; p = 0.003), pre-RT hemoglobin levels ≥ 7.45 mmol/l (12 g/dl; RR: 2.03; 95 % CI: 1.04-3.94; p = 0.038), oropharyngeal cancer (RR: 1.25; 95 % CI: 1.01-1.55; p = 0.038) and T category T1-2 (RR: 1.81; 95 % CI: 1.24-2.79; p = 0.002) were significantly associated with improved LRC. T category T1-2 (RR: 1.90; 95 % CI: 1.25-3.06; p = 0.002) and N category N0-2a (RR: 5.22; 95 % CI: 1.96-18.09; p < 0.001) were significantly associated with better MFS. Pre-RT hemoglobin levels ≥ 7.45 mmol/l (RR: 2.44; 95 % CI: 1.27-4.74; p = 0.007), T category T1-2 (RR: 1.97; 95 % CI: 1.36-3.04; p < 0.001) and N category N0-2a (RR: 2.87; 95 % CI: 1.37-6.61; p = 0.005) were significantly associated with improved OS. Podoplanin expression ≤ 10 % showed a trend towards improved OS on both univariate (p = 0.050) and multivariate analysis (RR: 1.86; 95 % CI: 0.96-3.59; p = 0.07). CONCLUSION Treatment outcomes were significantly associated with performance status, pre-RT hemoglobin level, tumor site and tumor stage. Tumor cell expression of podoplanin ≤ 10 % showed a trend towards improved OS when compared to podoplanin expression of > 10 %.

Abstract
BACKGROUND AND PURPOSE This study investigated the prognostic value of androgen receptor (AR) expression of tumor cells in patients treated with surgery and subsequent radio(chemo)therapy for locally advanced squamous cell carcinoma of the head and neck (SCCHN). MATERIAL AND METHODS The impact of AR and 11 additional factors on locoregional control (LRC), metastases-free survival (MFS), and overall survival (OS) was retrospectively studied in 163 patients with nonmetastatic stage III/IV SCCHN. Additional factors included age, gender, ECOG performance status, pre-radiotherapy (pre-RT) hemoglobin levels, tumor site, histologic grade, T category, N category, HPV status, extent of resection, and concurrent chemotherapy. RESULTS On multivariate analysis, improved LRC was significantly associated with pre-RT hemoglobin levels≥12 g/dl (risk ratio [RR] 2.22; 95% confidence interval [CI] 1.19–4.13; p=0.013), tumor site (RR 1.39; 95% CI 1.14–1.70; p=0.001), lower T category (RR 1.67; 95% CI 1.18–2.44; p=0.003), and lower N category (RR 4.18; 95% CI 1.90–10.55; p<0.001). Improved MFS was associated with AR expression (RR 2.21; 95% CI 1.01–5.41; p=0.048), better ECOG performance status (RR 3.19; 95% CI 1.50–7.14; p=0.003), lower T category (RR 2.24; 95% CI 1.47–3.65; p<0.001), and lower N category (RR 5.33; 95% CI 2.07–16.63; p<0.001). OS was positively associated with AR expression (RR 1.99; 95% CI 1.06–4.00; p=0.032), better ECOG performance status (RR 2.20; 95% CI 1.20–4.09; p=0.010), pre-RT hemoglobin levels≥12 g/dl (RR 2.13; 95% CI 1.19–3.82; p=0.012), lower T category (RR 1.81; 95% CI 1.30–2.62; p<0.001), and lower N category (RR 3.41; 95% CI: 1.65–7.80; p<0.001). CONCLUSION Tumor cell expression of AR was an independent prognostic factor for MFS and OS and should be considered in future prospective trials.

Abstract
BACKGROUND AND PURPOSE Patients with locally advanced SCCHN have a poor prognosis. This study investigated the prognostic value of the tumor cell expression of the fibroblast growth factor 2 (FGF-2) in patients treated with surgery followed by radiotherapy. PATIENTS AND METHODS The impact of FGF-2-expression and 11 additional potential prognostic factors on loco-regional control (LRC), metastases-free survival (MFS), and overall survival (OS) was retrospectively evaluated in 146 patients. Additional factors included age, gender, performance status, pre-radiotherapy hemoglobin levels, tumor site, histologic grade, T-category, N-category, human papilloma virus (HPV) status, extent of resection, and chemotherapy. Univariate analyses were performed with the Kaplan-Meier method and the log-rank test, multivariate analyses with the Cox proportional hazard model. RESULTS On multivariate analysis, improved LRC was significantly associated with FGF-2-negativity [risk ratio (RR): 7.33; 95%-confidence interval (CI): 2.88-19.05; p<0.001], lower T-category (RR: 2.42; 95%-CI: 1.47-4.33; p<0.001), lower N-category (RR: 12.36; 95%-CI: 3.48-78.91; p<0.001), and pre-radiotherapy hemoglobin levels ≥ 12 g/dl (RR: 4.18; 95%-CI: 1.73-10.53; p=0.002). No factor was significantly associated with improved MFS. Lower T-category showed a trend (RR: 1.59; 95%-CI: 0.97-2.82; p=0.069). Better OS was significantly associated with FGF-2-negativity (RR: 5.10; 2.22-11.80; p<0.001), lower T-category (RR: 2.17; 95%-CI: 1.38-3.68; p < 0.001), lower N-category (RR: 3.86; 95%-CI: 1.60-10.85; p=0.002), and pre-radiotherapy hemoglobin levels ≥ 12 g/dl (RR: 3.20; 95%-CI: 1.46-7.30; p=0.004). HPV-positivity showed a trend (RR: 2.36; 95%-CI: n.a.; p=0.054). CONCLUSIONS Tumor cell expression of FGF-2 proved to be an independent prognostic factor for LRC and OS. This factor can help personalize treatment and stratify patients in future trials.

Abstract
BACKGROUND AND PURPOSE This study re-evaluated the prognostic value of HPV status for loco-regional control (LRC), metastases-free survival (MFS), and survival (OS) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). A modified definition of HPV positivity was used in the current study compared to the authors' previous study. PATIENTS AND METHODS In the previous study of the same 170 patients, a tumor was defined as HPV-positive if it showed a positive in situ hybridization result in ≥10% of tumor cells and/or positive p16 immunostaining. In the current analysis, tumors were considered HPV-positive only if they showed positive results for both in situ hybridization and p16 immunostaining. In addition to HPV status, the same 11 potential prognostic factors were investigated for treatment outcomes as in the preceding study. RESULTS In the multivariate analysis of the current study, HPV positivity was significantly associated with improved LRC [risk ratio (RR) 9.78; p<0.001], MFS (RR 7.17; p=0.008), and OS (RR 6.61; p<0.001). In the previous study, HPV positivity was associated with LRC (RR 2.34; p=0.014) and OS (RR 2.19; p=0.019), but not with MFS (RR 2.04; p=0.11). CONCLUSIONS Applying the new definition of HPV positivity, the impact of HPV status on the prognosis of patients irradiated for locally advanced SCCHN was more prominent than in our previous study and associated with all three investigated endpoints.

Abstract
BACKGROUND AND PURPOSE This study investigated the prognostic value of tumor cell expression of vascular endothelial growth factor (VEGF) and its receptor fms-related tyrosine kinase 1 (FLT-1) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) who had been treated with adjuvant radiotherapy or radiochemotherapy. MATERIAL AND METHODS The impact of tumor cell VEGF and FLT-1 expression plus 11 additional factors on loco-regional control (LRC), metastases-free survival (MFS) and overall survival (OS) was retrospectively evaluated in 157 patients. The additional factors were age, gender, performance status, pre-radiotherapy (pre-RT) hemoglobin levels, tumor site, histologic grade, T-category, N-category, human papillomavirus (HPV) status, extent of resection and chemotherapy. RESULTS On multivariate analysis, improved LRC was significantly associated with an absence of VEGF expression (risk ratio, RR: 5.02; p = 0.009), lower T-category (RR: 2.00; p < 0.001), lower N-category (RR: 3.75; p < 0.001) and pre-RT hemoglobin levels ≥ 12 g/dl (RR: 2.20; p = 0.029). Improved MFS was significantly associated with an absence of VEGF expression (RR: 7.46; p = 0.002), lower T-category (RR: 1.97; p = 0.002), lower N-category (RR: 3.29; p = 0.005) and a favorable tumor location (RR: 1.34; p = 0.033); HPV positivity showed a trend towards improved MFS (RR: 1.43; p = 0.09). Improved OS was significantly associated with an absence of VEFG expression (RR: 3.22; p = 0.041), pre-RT hemoglobin levels ≥ 12 g/dl (RR: 2.47; p = 0.009), lower T-category (RR: 1.92; p < 0.001) and lower N-category (RR: 3.39; p < 0.001). FLT-1 expression was significantly associated with LRC and OS in the univariate but not in the multivariate analysis. CONCLUSION VEGF expression proved to be an independent negative predictor for LRC, MFS and OS in patients treated for locally advanced SCCHN with adjuvant radiotherapy or radiochemotherapy. FLT-1 expression was not significant in multivariate analyses.

Abstract
PURPOSE The purpose was to examine the effect of pretreatment weight status on loco-regional progression for patients with squamous cell carcinoma of the head and neck (SCCHN) after receiving definitive concurrent chemoradiation therapy (CCRT). METHODS In an expanded cohort of 140 patients, we retrospectively reviewed weight status and loco-regional progression of SCCHN patients treated with CCRT between 2004 and 2010. RESULTS Pretreatment ideal body weight percentage (IBW%) was statistically significantly different for patients with disease progression than for those without progression (p = 0.02) but was not an independent predictor of progression. Median pretreatment IBW% was 118 (72-193) for the progression-free group and was 101.5 (73-163) for the group with progression. Both groups suffered clinically severe weight loss of approximately 9 % from baseline to end treatment. CONCLUSIONS Pretreatment weight status, a very crude indicator of nutrition status, may have prognostic value in patients with SCCHN undergoing definitive CCRT. Inadequate nutritional status in these patients has been associated with poor clinical outcomes and decreased quality of life. Based on this report and others, the best next steps include routine validated malnutrition screening and the testing of evidence-based nutrition care protocols with the goals of minimizing weight loss and improvement of quality of life.

Abstract
BACKGROUND AND PURPOSE This study investigated the prognostic role of tumor cell expression of erythropoietin (EPO) and its receptor (EPO-R) in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) treated with surgery plus radiotherapy. PATIENTS AND METHODS The impact of EPO, EPO-R, and 11 additional factors on locoregional control (LRC), metastases-free survival (MFS), and overall survival (OS) was retrospectively evaluated in 144 patients. Additional factors were age, gender, performance status, preradiotherapy (pre-RT) hemoglobin levels, tumor site, histologic grade, T category, N category, human papillomavirus (HPV) status, extent of resection, and chemotherapy. Univariate analyses were performed with the Kaplan-Meier method and the log-rank test, multivariate analyses with the Cox proportional hazard model. RESULTS On multivariate analysis, improved LRC was significantly associated with no EPO expression (risk ratio [RR] 3.72; 95 % confidence interval [CI] 1.35-15.42; p = 0.008), lower T category (RR 1.60; 95 %CI 1.14-2.32; p = 0.005), and oropharynx or larynx cancer (RR 1.23; 95 %CI 1.02-1.49; p = 0.033). Improved MFS was significantly associated with no EPO expression (RR 5.45; 95 %CI 1.13-97.81; p = 0.031), lower T category (RR 1.66; 95 %CI 1.11-2.65; p = 0.013), lower N category (RR 2.44; 95 %CI 1.04-6.66; p = 0.039), HPV positivity (RR 3.14; 95 %CI not available; p = 0.034), and oropharynx or larynx cancer (RR 1.28; 95 %CI 1.01-1.61; p = 0.041). Improved OS was significantly associated with no EPO expression (RR 4.77; 95 %CI 1.63-20.68; p = 0.003), no EPO-R expression (RR 2.36; 95 %CI 1.22-4.92; p = 0.010), lower T category (RR 1.44; 95 %CI 1.04-2.04; p = 0.027), oropharynx or larynx cancer (RR 1.30; 95 %CI 1.08-1.57; p = 0.007), and pre-RT hemoglobin ≥ 12 g/dl (RR 1.94; 95 %CI 1.03-3.65; p = 0.042). CONCLUSION EPO expression of tumor cells was an independent prognostic factor for LRC, MFS, and OS. EPO-R expression was an independent prognostic factor for OS.

Abstract
BACKGROUND The purpose of this study was to quantify the effect of treatment duration on locoregional progression after definitive concurrent chemoradiation (CCRT) for squamous cell carcinoma of the head and neck (SCCHN). METHODS We conducted a retrospective chart review of patients treated between 2004 and 2010. After a prior analysis, measures were taken to limit therapy beyond 7 weeks. Comparison of outcomes were made between cohorts 1 (2004-2007, n = 78) and 2 (2007-2010, n = 62). RESULTS Median therapy duration was statistically significantly different between cohorts as follows: 51 days, cohort 1 and 46 days, cohort 2 (p < .01). Locoregional progression in cohorts 1 and 2 was 19% and 5% (p = .01), respectively. On multivariate analysis, patients with prolonged treatment (≥57 days) had an 8-fold increase in risk of locoregional progression compared to patients who completed on time (p < .01). CONCLUSION Treatment duration was a significant predictor of locoregional progression in patients with SCCHN who received definitive CCRT.

Abstract
Treatment responses of N0 stage nasopharyngeal carcinoma were firstly analyzed comprehensively to evaluate long term outcomes of patients and identify prognostic factors. A total of 610 patients with N0 NPC, undergoing definitive radiotherapy to their primary lesion and prophylactic radiation to upper neck, were reviewed retrospectively. Concomitant chemotherapy was administrated to 65 out of the 610. Survival rates of the patients were calculated using the Kaplan-Meier method and compared by log-rank test. Prognostic factors were identified by the Cox regression model. The study revealed the 5-year and 10-year overall, disease-free, disease-specific, local failure-free, regional failure-free, locoregional failure-free and distant metastasis-free survival rates to be 78.7% and 66.8%, 68.8% and 55.8%, 79.9% and 70.4%, 81.2% and 72.5%, 95.8% and 91.8%, 78.3% and 68.5%, 88.5% and 85.5%, respectively. There were 192 patients experiencing failure (31.5%) after radiotherapy or chemoradiotherapy. Of these, local recurrence, regional relapse and distant metastases as the first event of failure occurred in 100 (100/610, 16.4%), 15(15/610, 2.5%) and 52 (52/610, 8.5%), respectively. Multivariate analysis showed that T stage was the only independent prognostic factor for patients with N0 NPC (P=0.000). Late T stage (P=0.000), male (P=0.039) and anemia (P=0.007) were independently unfavorable factors predicting disease-free survival. After treatment, satisfactory outcome wasgenerally achieved in patients with N0 NPC. Local recurrence represented the predominant mode of treatment failure, while T stage was the only independent prognostic factor for overall survival. Late T stage, male gender, and anemia independently predicted lower possibility of the disease-free survival.

Abstract
BACKGROUND Racial and ethnic minorities as well as other vulnerable populations experience disparate cancer-related health outcomes. Patient navigation is an emerging health care delivery innovation that offers promise in improving quality of cancer care delivery to these patients who experience unique health-access barriers. Metrics are needed to evaluate whether patient navigation can improve quality of care delivery, health outcomes, and overall value in health care during diagnosis and treatment of cancer. METHODS Information regarding the current state of the science examining patient navigation interventions was gathered via search of the published scientific literature. A focus group of providers, patient navigators, and health-policy experts was convened as part of the Patient Navigation Leadership Summit sponsored by the American Cancer Society. Key metrics were identified for assessing the efficacy of patient navigation in cancer diagnosis and treatment. RESULTS Patient navigation data exist for all stages of cancer care; however, the literature is more robust for its implementation during prevention, screening, and early diagnostic workup of cancer. Relatively fewer data are reported for outcomes and efficacy of patient navigation during cancer treatment. Metrics are proposed for a policy-relevant research agenda to evaluate the efficacy of patient navigation in cancer diagnosis and treatment. CONCLUSIONS Patient navigation is understudied with respect to its use in cancer diagnosis and treatment. Core metrics are defined to evaluate its efficacy in improving outcomes and mitigating health-access barriers.

Abstract
PURPOSE To investigate the effect of hemoglobin (Hb) concentration and the difference in its decrease during treatment on outcome of radiotherapy (RT) alone for patients with Stage I and II nasopharyngeal carcinoma. METHODS AND MATERIALS A total of 572 patients with Stage I-II nasopharyngeal carcinoma with RT alone between January 2001 and December 2004 were retrospectively analyzed. Patient characteristics, tumor variables, and Hb level, including pre-RT Hb, mid-RT Hb, and dynamic change of Hb between pre- and post- RT and its difference in decrease (▵Hb) were subjected to univariate and multivariable analysis to identify factors that predict disease-specific survival (DSS), local regional recurrence-free survival (LRFS), and metastases-free survival (MFS). RESULTS The 5-year DSS was poorer in the Hb continuous decrease group than in the Hb noncontinuous decrease group (84% vs. 89%; p = 0.008). There was poorer 5-year DSS in patients with ▵Hb of >11.5 g/L than in those with ▵Hb of ≤11.5 g/L (82% vs. 89%; p = 0.001), and poorer LRFS (79% vs. 83%; p = 0.035). Univariate and multivariate analysis showed that Hb decrease difference with greater than 11.5 g/L was an independent prognostic factor for DSS and LRFS. CONCLUSIONS The difference in decrease of Hb level during the course of radiation treatment appeared as a poor prognostic factor in Stage I and II nasopharyngeal carcinoma patients.

Abstract
Purpose/Objective(s): American Indians (AIs) present with more advanced stages of cancer and, therefore, suffer from higher cancer mortality rates compared to non-AIs. Under the National Cancer Institute (NCI) Cancer Disparities Research Partnership (CDRP) Program, we have been researching methods of improving cancer treatment and outcomes since 2002, for AIs in Western South Dakota, through the Walking Forward (WF) Program. Materials/Methods: This program consists of (a) a culturally tailored patient navigation program that facilitated access to innovative clinical trials in conjunction with a comprehensive educational program encouraging screening and early detection, (b), surveys to evaluate barriers to access, (c) clinical trials focusing on reducing treatment length to facilitate enhanced participation using brachytherapy and intensity modulated radiotherapy (IMRT) for breast and prostate cancer, as AIs live a median of 140 miles from the cancer center, and (d) a molecular study (ataxia telangiectasia mutated) to address whether there is a specific profile that increases toxicity risks. Results: We describe the design and implementation of this program, summary of previously published results, and ongoing research to influence stage at presentation. Some of the critical outcomes include the successful implementation of a community-based research program, development of trust within tribal communities, identification of barriers, analysis of nearly 400 navigated cancer patients, clinical trial accrual rate of 10%, and total enrollment of nearly 2,500 AIs on WF research studies. Conclusion: This NCI funded pilot program has achieved some initial measures of success. A research infrastructure has been created in a community setting to address new research questions and interventions. Efforts underway to promote cancer education and screening are presented, as well as applications of the lessons learned to other health disparity populations – both nationally and internationally.

Abstract
BACKGROUND This study was carried out to determine if markers of nutritional status predict for locoregional failure following intensity-modulated radiation therapy (IMRT) with concurrent chemoradiotherapy (CCRT) for squamous cell carcinoma of the head and neck (SCCHN). METHODS We performed a retrospective chart review of 78 patients with SCCHN who received definitive CCRT. We compared patient factors, tumor characteristics, and nutritional status indicators between patients with and without locoregional failure. RESULTS Fifteen of 78 patients (19%) experienced locoregional failure. Median follow-up for live patients was 38 months. On univariate analysis, pretreatment percentage of ideal body weight (%IBW) (p < .01), pretreatment hemoglobin (p = .04), and treatment duration (p < .01) were significant predictors of failure. On multivariate analysis, pretreatment %IBW (p = .04) and treatment time (p < .01) remained statistically significant. CONCLUSIONS Although treatment time is an accepted risk factor for failure, differences in outcome for patients with head and neck cancer undergoing definitive CCRT based on pretreatment %IBW should be examined further.

Abstract
BACKGROUND A study was undertaken to assess patient navigation utilization and its impact on treatment interruptions and clinical trial enrollment among American Indian cancer patients. METHODS Between February 2004 and September 2009, 332 American Indian cancer patients received patient navigation services throughout cancer treatment. The patient navigation program provided culturally competent navigators to assist patients with navigating cancer therapy, obtaining medications, insurance issues, communicating with medical providers, and travel and lodging logistics. Data on utilization and trial enrollment were prospectively collected. Data for a historical control group of 70 American Indian patients who did not receive patient navigation services were used to compare treatment interruptions among those undergoing patient navigation during curative radiation therapy (subgroup of 123 patients). RESULTS The median number of contacts with a navigator was 12 (range, 1-119). The median time spent with the navigator at first contact was 40 minutes (range, 10-250 minutes), and it was 15 minutes for subsequent contacts. Patients treated with radiation therapy with curative intent who underwent patient navigation had fewer days of treatment interruption (mean, 1.7 days; 95% confidence interval [CI], 1.1-2.2 days) than historical controls who did not receive patient navigation services (mean, 4.9 days; 95% CI, 2.9-6.9 days). Of the 332 patients, 72 (22%; 95% CI, 17%-26%) were enrolled on a clinical treatment trial or cancer control protocol. CONCLUSIONS Patient navigation was associated with fewer treatment interruptions and relatively high rates of clinical trial enrollment among American Indian cancer patients compared with national reports.
