Dealing with the Vicissitudes and Abject Consequences of Head and Neck Cancer: A Vital Role for Psycho-Oncology.

Patients with head and neck cancer face important life-altering effects in appearance and function, affecting distress and quality of life and requiring the involvement of a multidisciplinary team. Psycho-oncology makes an important contribution to the field, as head and neck cancers carry a huge adaptational toll. To illustrate the value of this discipline, we report two cases of patients with advanced head and neck cancer for which the treatment-related body changes were of major significance. A commentary by the treating surgeons and psycho-oncologists precedes a general discussion about the clinical management of such patients. The article outlines strategies to address health literacy, doctor-patient communication, treatment decision-making, and emotional distress; placing the person at the center of oncological care. It calls for the broad application of principles of psychological first aid by healthcare professionals in oncology.

Preoperative TSH and thyroglobulin levels: would it predict thyroid cancer?

OBJECTIVE: The goal of this study is to determine whether preoperative TSH and Tg levels can be used as predictors of thyroid cancer. STUDY DESIGN: Retrospective chart review. METHODS: Charts of patients who had undergone thyroid surgery between 2006 and 2012 were subjected to review. Demographic data, preoperative TSH and Tg levels, and final histopathological results were recorded. Patients were divided depending on preoperative TSH and Tg levels. Group 1 consisted of patients with elevated TSH and Tg, Group 2 had elevated TSH only, Group 3 - elevated Tg only, and in Group 4 neither TSH nor Tg were elevated. RESULTS: 653 patient charts were reviewed and 386 patients were excluded due to incomplete information. 212 patients were female. Mean age was 50 years. Group 1 included 52 patients, 25 of them (48%) had well-differentiated thyroid cancer (WDTC). Relative risk was 1.59 and the odds ratio amounted to 1.79. Group 2 included 80 patients, 36 (45%) of whom had WDTC. Group 3 consisted of 58 patients, 23 (39.6%) of them with WDTC. Group 4 comprised 77 patients, where WDTC was present in 16 (20.8%) cases. CONCLUSION: TSH and Tg levels can aid in preoperative assessment of a thyroid nodule.

Ultrasound-guided fine-needle aspiration of thyroid nodules: does size matter?

PURPOSE: Some authors have questioned the benefit of fine-needle aspiration (FNA) of thyroid nodules ≥ 4 cm. They report that the results of the FNA are not as reliable when compared to nodules <4 cm. The aims of this study are to evaluate the accuracy and predictive values of ultrasound-guided FNA (USFNA) of thyroid nodules ≥ 4 cm and compare these findings to nodules <4 cm. METHODS: A retrospective study of 998 patients who underwent thyroid surgery between 2006 and 2012 at the McGill University Thyroid Cancer Center was performed. USFNA and post-operative pathology diagnoses of nodules ≥ 4 cm versus those <4 cm were compared. Pre-operative USFNA results were divided into three groups: benign, indeterminate, and malignant/suspicious for malignancy subgroups. Post-operative results were separated into benign and malignant groups. RESULTS: There were 225 patients with nodules ≥ 4 cm and 773 patients with nodules <4 cm. The sensitivity, specificity, positive predictive value and negative predictive value for USFNA of nodules ≥ 4 cm were 84.62% (CI 71.91-93.10), 91.49% (CI 79.6-97.58), 91.67% (CI 80.0-97.63) and 84.31% (CI 71.4-92.95), respectively. The sensitivity, specificity, positive predictive value and negative predictive value for USFNA of nodules <4 cm were 90.48% (CI 86.1-93.8), 85.92% (CI 75.6-93.02), 95.8% (CI 92.41-97.96) and 71.76% (CI 60.95-81.0), respectively. The difference in diagnostic accuracy of USFNA between both groups was not statistically significant (p>0.05). CONCLUSION: This study shows that the sensitivity, specificity, positive predictive value and negative predictive value for USFNA of nodules ≥ 4 cm are similar to that of smaller nodules. It is therefore suggested that these nodules undergo USFNA.

Sentinel Lymph Node Biopsy Status Correlates with Postoperative Stimulated Thyroglobulin Levels in Low-risk Papillary Thyroid Cancer Patients.

OBJECTIVE: Radioactive iodine (RAI) remnant ablation in low-risk papillary thyroid cancer (PTC) is controversial. Current patient selection guidelines recommend the use of postoperative stimulated thyroglobulin (stim-Tg), neck dissections, and sonography but fail to include sentinel lymph node biopsy (SLNB). The objective of this study was to evaluate the correlation between SLNB status and postoperative stimulated thyroglobulin as a surrogate marker of clinical outcome. METHODS: Retrospective chart review of low-risk PTC patients who underwent a total thyroidectomy with SLNB at the McGill Thyroid Cancer Center. SLNBs were obtained using methylene blue dye. Biochemical measurements were acquired between 4 and 12 weeks postoperatively. Statistical analyses were performed using logistic regression models and receiver operating characterisitc (ROC) curves. A P-value <.05 was considered significant. RESULTS: Ninety-six patients were included in this study. The positive SLNB rate was 14.6%. The mean postoperative Tg level was 1.41 µg/L. There were no significant correlations between the SLNB and the covariates analyzed (age, gender, histology, tumor size, and thyrotropin levels). Patients with negative SLNB were significantly more likely to have a lower stim-Tg (P<.0001). When postoperative Tg was analyzed as a categorical variable, a threshold of <1 µg/L was significantly associated with a negative SLNB, with a sensitivity and specificity (determined by ROC curves) of 0.86 and 0.88, respectively. CONCLUSION: There exists a correlation between SLNB and postoperative Tg. This creates the possibility of a new approach to RAI administration among low-risk PTC patients incorporating SLNB to the current guidelines.

Serum thyroglobulin improves the sensitivity of the McGill Thyroid Nodule Score for well-differentiated thyroid cancer.

BACKGROUND: The McGill Thyroid Nodule Score (MTNS) is a scoring system devised to help physicians to assess the preoperative risk that a thyroid nodule is malignant. It uses 22 different known risk factors for thyroid cancer (radiation exposure, microcalcifications on ultrasound, positive HBME-1 stain on biopsy, etc.) and attributes a percentage risk that the nodule is malignant. Recently, preoperative thyroglobulin (Tg) levels have been shown to correlate with the risk of malignancy. The aim of this study was to incorporate Tg levels into the already established MTNS. METHODS: This is a retrospective analysis of 184 thyroidectomy patients at the McGill University Thyroid Cancer Center. Patients with preoperative Tg levels were included in the study, and patients with incidental papillary microcarcinoma without extrathyroidal extent on final pathology were excluded. MTNS scores were calculated for all patients. Preoperative Tg levels of 75 ng/mL added one point to the MTNS, and levels of 187.5 ng/mL added two points. The new system is named MTNS+. RESULTS: Malignancy rates were calculated for each MTNS+ score. Patients with a score of 0-1 were <5% at risk of malignancy. The malignancy rate for scores of 2-3 was 14.29%, followed by 28.95% for scores of 4-6, 32.65% for scores of 7-8, 64.86% for scores of 9-11, 71.43% for scores of 12-14, 78.57% for scores of 15-18, and 92.31% for scores of 19-22. All patients (five of five) with an MTNS+ score of 23 or more had a malignant final pathology result. Patients with scores greater than eight had a relative risk of 2.5 [CI 1.79-3.49] of malignancy compared to patients with lower scores. MTNS+ showed good specificity at higher scores, with 89%, 96%, and 100% at scores above 11, 14, and 20 respectively. Compared to MTNS, adding Tg levels did not improve positive predictive values (PPV) or specificity, but improved sensitivity by 7.89% for scores greater than eight, and by up to 10.48% for scores greater than seven. CONCLUSION: This study shows that adding Tg to the MTNS increases the sensitivity of this scoring system. Moreover, it suggests that a combined scoring system such as the MTNS+ can accurately stratify the risk of well-differentiated malignancy in patients with thyroid nodules.

Head and neck cancer patients want us to support them psychologically in the posttreatment period: Survey results.

OBJECTIVES: No study systematically has investigated the supportive care needs of general head and neck cancer patients using validated measures. These needs include physical and daily living needs, health system and information needs, patient care and support needs, psychological needs, and sexuality needs. Identifying the unmet needs of head and neck cancer patients is a necessary first step to improving the care we provide to patients seen in our head and neck oncology clinics. It is recommended as the first step in intervention development in the Pan-Canadian Clinical Practice Guideline of the Canadian Partnership Against Cancer (see Howell, 2009). This study aimed to identify: (1) met and unmet supportive care needs of head and neck cancer patients, and (2) variability in needs according to demographics, disease variables, level of distress, and quality-of-life domains. METHODS: Participants were recruited from the otolaryngology-head and neck surgery clinics of two university teaching hospitals. Self-administered questionnaires included sociodemographic and medical questions, as well as validated measures such as the Supportive Care Needs Survey-Short Form (SCNS-SF34), the Hospital Anxiety and Depression Scale (HADS), and the Functional Assessment of Cancer Therapy-General (FACT-G) and Head and Neck Module (FACT-H&N) (quality of life measures). RESULTS: One hundred and twenty-seven patients participated in the survey. 68% of them experienced unmet needs, and 25% revealed a clinically significant distress level on the HADS. The highest unmet needs were psychological (7 of top 10 needs). A multiple linear regression indicated a higher level of overall unmet needs when patients were divorced, had a high level of anxiety (HADS subscale), were in poor physical condition, or had a diminished emotional quality of life (FACT-G subscales). SIGNIFICANCE OF RESULTS: The results of this study highlight the overwhelming presence of unmet psychological needs in head and neck cancer patients and underline the importance of implementing interventions to address these areas perceived by patients as important. In line with hospital resource allocation and cost-effectiveness, one may also contemplate screening patients for high levels of anxiety, as well as target patients who are divorced and present low levels of physical well-being, as these patients may have more overall needs to be met.
