Metabolite Biomarkers of Prolonged and Intensified Pain and Distress in Head and Neck Cancer Patients Undergoing Radio- or Chemoradiotherapy by Means of NMR-Based Metabolomics-A Preliminary Study.

Treatment of head and neck squamous cell carcinoma (HNSCC) has a detrimental impact on patient quality of life. The rate of recognized distress/depression among HNSCC patients ranges from 9.8% to 83.8%, and the estimated prevalence of depression among patients receiving radiotherapy is 63%. Shorter overall survival also occurs in preexisting depression or depressive conditions. The present study analyzes the nuclear magnetic resonance (NMR) blood serum metabolic profiles during radio-/chemoradiotherapy and correlates the detected alterations with pain and/or distress accumulated with the disease and its treatment. NMR spectra were acquired on a Bruker 400 MHz spectrometer and analyzed using multivariate methods. The results indicate that distress and/or pain primarily affect the serum lipids and metabolites of energy (glutamine, glucose, lactate, acetate) and one-carbon (glycine, choline, betaine, methanol, threonine, serine, histidine, formate) metabolism. Sparse disturbances in the branched-chain amino acids (BCAA) and in the metabolites involved in protein metabolism (lysine, tyrosine, phenylalanine) are also observed. Depending on the treatment modality-radiotherapy or concurrent chemoradiotherapy-there are some differences in the altered metabolites.

Walking through the valley of the shadow of death-The psychotherapy of the head and neck cancer patient expressing suicidal ideations and impulses.

The paper aims to show the multilevel and complex cooperation and the inclusion of the psychotherapist leading the psychotherapy in the medical team at the radiotherapy and clinical oncology clinic. We illustrate these interventions with the case of Stan. This 43-year-old firefighter was diagnosed with advanced head and neck cancer and pre-existing mental health problems meeting the criteria of ICD-10: obsessive-compulsive disorder, post-traumatic stress disorder and psychoactive substance abuse. During the treatment, suicidal thoughts and impulses emerged, triggered at the hospital by electronic noises and the feeling of entrapment without a way out. This situation put the patient at high risk and the whole healthcare team needed an urgent effective response. The patient agreed to stay in the secured room, where he was cared for by doctors, nurses, a dietitian, and a psychotherapist. He actively attended daily sessions with noticeable engagement. Psychotherapy sessions focused on alleviating posttraumatic stress disorder and OCD. Mindfulness and breathwork-based exercises were implemented to increase non-judgemental self-awareness and regulate the over-aroused nervous system. As a result, the patient's mental health has improved and the completion of the cancer treatment was possible. Psychotherapy, good therapeutic alliance, and attentive teamwork effectively managed his mental health and treatment-related symptoms.

Low Post-Treatment Quality of Life and the High Incidence of Pain Are Common and Significantly Exacerbated in Depressed Head and Neck Patients Treated with Definitive Accelerated Radiotherapy.

(1) Background: The goal of this study is to evaluate psychological tolerance and health-related quality of life (QOL) in head and neck (HN) cancer patients treated with definitive accelerated radiotherapy (DART). (2) Methods: 76 recurrence-free patients eligible for the study, who were treated with DART in the CAIR-2 phase III clinical study (median of follow-up = 47 months), completed EORTC QLQ-C30 with the H&N35 module, Hospital Anxiety and Depression Scale (HADS) and Visual-Analog Scales (VAS) of pain in HN and the neck/arm areas. (3) Results: The most dominant symptoms measured with QLQ-C30 were as follows: fatigue (44/100), sleeplessness (39/100), financial problems (38/100) and pain (32/100). Within the H&N35, the highest scores were reported on the subscales of sticky saliva (60/100), mouth dryness (65/100) and increased intake of painkillers (50/100). Pain (VAS) was reported by 87% (HN area) and 78% (shoulder area) of the patients, with a mean score of 3/10. One-third of the patients reported depressive moods (HADS ≥ 15 points) with an average score of 12.5/42 p. The depressed group, who smoked more as compared to the non-depressed group before DART (96% vs. 78%) and required steroids treatment (85% vs. 58%) during DART, also scored significantly worse on 23 of the 35 subscales of QLQ-C30 and H&N35 and experienced more intense pain (VAS). Women and less-advanced patients scored better in several aspects of quality of life. (4) Conclusions: Patients treated with DART struggle with low quality of life and persistent treatment-related symptoms including constant pain. HNC survivors, especially those who are depressed, may require additional psychosocial, rehabilitation and medical intervention programmes.

Tolerability and toxicity of prophylactic cranial irradiation in patients with non-small cell lung cancer - Results of a phase II study (with estimation of hematological toxicity, pituitary function and magnetic resonance spectra changes).

AIM: To evaluate the tolerability and toxicity of PCI in patients with NSCLC. BACKGROUND: Prophylactic cranial irradiation (PCI) is a standard treatment for patients with small cell lung cancer. There are data showing a decreasing ratio of brain metastases after PCI for non-small cell lung cancer (NSCLC-non small cell lung cancer) patients but, so far, there is no evidence for increasing overall survival. The main concern in this setting is the tolerance and toxicity of the treatment. MATERIALS AND METHODS: From 1999 to 2007, 50 patients with NSCLC treated with radical intent underwent PCI (30 Gy in 15 fractions). Mean follow-up was 2.8 years. The tolerability and hematological toxicity were evaluated in all patients, a part of participants had done neuropsychological tests, magnetic resonance imaging with (1)H nuclear magnetic resonance spectra, and estimation of pituitary function. RESULTS: During follow-up, 20 patients developed distant metastases, 4-brain metastases. Fourteen (30%) patients had acute side effects: (headache, nausea, erythema of the skin). The symptoms did not require treatment breaks. Six patients complained of late side effects (vertigo, nausea, anxiety, lower extremity weakness, deterioration of hearing and olfactory hyperesthesia). Hematological complications were not observed. Testosterone levels tended to decrease (p = 0.062). Visual-motor function deteriorated after treatment (p < 0.059). Performance IQ decreased (p < 0.025) and the difference between performance IQ and verbal IQ increased (p < 0.011). Degenerative periventricular vascular changes were observed in two patients. Analysis of the spectroscopic data showed metabolic but reversible alterations after PCI. CONCLUSION: PCI in the current series was well tolerated and associated with a relatively low toxicity.

Radiation-free weekend rescued! Continuous accelerated irradiation of 7-days per week is equal to accelerated fractionation with concomitant boost of 7 fractions in 5-days per week: report on phase 3 clinical trial in head-and-neck cancer patients.

PURPOSE: To report long-term results of randomized trial comparing 2 accelerated fractionations of definitive radiation therapy assessing the need to irradiate during weekend in patients with head and neck squamous cell carcinoma. METHODS AND MATERIALS: A total of 345 patients with SCC of the oral cavity, larynx, and oro- or hypo-pharynx, stage T2-4N0-1M0, were randomized to receive continuous accelerated irradiation (CAIR: once per day, 7 days per week) or concomitant accelerated boost (CB: once per day, 3 days per week, and twice per day, 2 days per week). Total dose ranged from 66.6-72 Gy, dose per fraction was 1.8 Gy, number of fractions ranged from 37-40 fractions, and overall treatment time ranged from 37-40 days. RESULTS: No differences for all trial end-points were noted. At 5 and 10 years, the actuarial rates of local-regional control were 63% and 60% for CAIR vs 65% and 60% for CB, and the corresponding overall survival were 40% and 25% vs 44% and 25%, respectively. Confluent mucositis was the main acute toxicity, with an incidence of 89% in CAIR and 86% in CB patients. The 5-year rate of grade 3-4 late radiation morbidity was 6% for both regimens. CONCLUSIONS: Results of this trial indicate that the effects of accelerated fractionation can be achieve by delivering twice-per-day irradiation on weekday(s). This trial has also confirmed that an accelerated, 6-weeks schedule is a reasonable option for patients with intermediate-stage head-and-neck squamous cell carcinoma because of the associated high cure rate and minimal severe late toxicity.

Information for decision making by patients with early-stage prostate cancer: a comparison across 9 countries.

PURPOSE: To describe decisional roles of patients with early-stage prostate cancer in 9 countries and to compare the information they rated important for decision making (DM). METHOD: A survey of recently treated patients was conducted in Canada, Italy, England, Germany, Poland, Portugal, Netherlands, Spain, and Turkey. Participants indicated their decisional role in their actual decision and the role they would prefer now. Each participant also rated (essential/desired/no opinion/avoid) the importance of obtaining answers, between diagnosis and treatment decision, to each of 92 questions. For each essential/desired question, participants specified all purposes for that information (to help them: understand/decide/plan/not sure/other). RESULTS: A total of 659 patients participated with country-specific response rates between 58%-77%. Between 83%-96% of each country's participants recalled actually taking an active decisional role and, in most countries, that increased slightly if they were to make the decision today; there were no significant differences among countries. There was a small reliable difference in the mean number of questions rated essential for DM across countries. More striking, however, was the wide variability within each country: no question was rated essential for DM by even 50% of its participants but almost every question was rated essential by some. CONCLUSIONS: Almost all participants from each country want to participate in their treatment decisions. Although there are country-specific differences in the amount of information required, wide variation within each country suggests that information that patients feel is essential or desired for DM should be addressed on an individual basis in all countries.

Information needs of early-stage prostate cancer patients: a comparison of nine countries.

BACKGROUND AND PURPOSE: Providing information to patients can improve their medical and psychological outcomes. We sought to identify core information needs common to most early-stage prostate cancer patients in participating countries. MATERIAL AND METHODS: Convenience samples of patients treated 3-24 months earlier were surveyed in Canada, England, Italy, Germany, Poland, Portugal, Netherlands, Spain, and Turkey. Each participant rated the importance of addressing each of 92 questions in the diagnosis-to-treatment decision interval (essential/desired/no opinion/avoid). Multivariate modelling determined the extent of variance accounted by covariates, and produced an unbiased prediction of the proportion of essential responses for each question. RESULTS: Six hundred and fifty-nine patients responded (response rates 45-77%). On average, 35-53 questions were essential within each country; similar questions were essential to most patients in most countries. Beyond cross-country similarities, each country showed wide variability in the number and which questions were essential. Multivariate modelling showed an adjusted R-squared with predictors country, age, education, and treatment group of only 6% of the variance. A core of 20 questions were predicted to be essential to >2/3 of patients. CONCLUSIONS: Core information can be identified across countries. However, providing the core should only be a first step; each country should then provide information tailored to the needs of the individual patient.
