This study revealed that physicians' survival estimates were unreliable, especially in the case of patients near death. Self-reported emotional distress and objective PFs may improve the accuracy of survival estimates.

BACKGROUND:The purpose of the study was to investigate the adequacy of palliative radiation treatment in endstage cancer patients. METHODS: Of 216 patients referred for palliative radiotherapy, 33 died within 30 days and constitute the population of the study. Symptoms, Karnofsky Performance Status (KPS), laboratory tests, and survival estimates were obtained. Treatment course was evaluated by medical records. Univariate analyses were performed by using the 2-sided chi-square test. With significant variables, multiple regression analysis was performed. RESULTS: Median age was 65 years, and median survival was 15 days. Prevailing primary cancer types were lung (39%) and breast (18%). Metastases were present in 94% of patients, brain (36%), bone (24%) and lung (18%). In 91%, KPS was <50%. KPS, lactate dehydrogenase, dyspnea, leucocytosis, and brain metastases conveyed a poor prognosis. From 85 survival estimates, only 16% were correct, but 21% expected more than 6 months. Radiotherapy was delivered to 91% of patients. In 90% of radiation treatments, regimens of at least 30 Gy with fractions of 2-3 Gy were applied. Half of the patients spent greater than 60% of their remaining lifespan on therapy. In only 58% of patients was radiotherapy completed. Progressive complaints were noted in 52% and palliation in 26%. CONCLUSIONS: Radiotherapy was not appropriately customized to these patients considering the median treatment time, which resembles the median survival time. About half of the patients did not benefit despite spending most of their remaining lives on therapy. Prolonged irradiation schedules probably reflect overly optimistic prognoses and unrealistic concerns about late radiation damage. Single-fraction radiotherapy was too seldom used.

Additional induction CHX with TPF before RT-CHX does not improve OS and PFS in locally advanced HNSCC compared to definite RT-CHX.

Combination of neoadjuvant chemo-/radiotherapy results in significantly higher rates of complete remission than neoadjuvant chemotherapy alone. The significance for tumor-free and overall survival has to be evaluated.

These findings indicate that cetuximab may have the potential to enhance the severity of radiation dermatitis in HNC patients. A systematic monitoring of cutaneous side effects during radiotherapy plus cetuximab is advised in order to reliably estimate the frequency of severe (grade 3/4) radiation dermatitis.

Tumor stage, histology, complete resection, and tumor size had a significant impact on survival. Myasthenia may facilitate early detection and is correlated with superior survival. When postoperative radiotherapy is administered, doses above 50 Gy may improve outcome.

Cystatin C-based GFR estimates showed the overall strongest correlation to the reference method. Thus, we recommend cystatin C for GFR estimation in HNC patients as an alternative method to the estimated creatinine clearance in clinical practice.
