Distress in Spouses and Patients After Treatment for Head and Neck Cancer

Background: The objective of this study is to obtain insight into distress in spouses and patients treated for head and neck cancer.

Patient-reported symptom questionnaires in laryngeal cancer: Voice, speech and swallowing

OBJECTIVES To validate questionnaires on voice, speech, and swallowing among laryngeal cancer patients, to assess the need for and use of rehabilitation services, and to determine the association between voice, speech, and swallowing problems, and quality of life and distress. MATERIALS AND METHODS Laryngeal cancer patients at least three months post-treatment completed the VHI (voice), SHI (speech), SWAL-QOL (swallowing), EORTC QLQ-C30, QLQ-HN35, HADS, and study-specific questions on rehabilitation. RESULTS Eighty-eight patients and 110 healthy controls participated. Cut off scores of 15, 6, and 14 were defined for the VHI, SHI, and SWAL-QOL (sensitivity > 90%; specificity > 80%). Based on these scores, 56% of the patients reported voice, 63% speech, and 54% swallowing problems. VHI, SHI, and SWAL-QOL scores were associated significantly with quality of life (EORTC QLQ-C30 global quality of life scale) (r = .43 (VHI and SHI) and r = .46 (SWAL-QOL)) and distress (r = .50 (VHI and SHI) and r = .58 (SWAL-QOL)). In retrospect, 32% of the patients indicated the need for rehabilitation at time of treatment, and 81% of these patients availed themselves of such services. Post-treatment, 8% of the patients expressed a need for rehabilitation, and 20% of these patients actually made use of such services. CONCLUSION Psychometric characteristics of the VHI, SHI, and SWAL-QOL in laryngeal cancer patients are good. The prevalence of voice, speech, and swallowing problems is high, and clearly related to quality of life and distress. Although higher during than after treatment, the perceived need for and use of rehabilitation services is limited.

Molecular detection of minimal residual cancer in surgical margins of head and neck cancer patients

A great disappointment in head and neck cancer surgery is that 10–30% of head and neck squamous cell carcinoma (HNSCC) patients develop local recurrences despite histopathologically tumor-free surgical margins. These recurrences result from either minimal residual cancer (MRC) or preneoplastic lesions that remain behind after tumor resection. Distinguishing MRC from preneoplasic lesions is important to tailor postoperative radiotherapy more adequately. Here we investigated the suitability of quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) using human Ly-6D (hLy-6D) transcripts as molecular marker to detect MRC in surgical margins. Submucosal samples of deep surgical margins were collected from 18 non-cancer control patients and 67 HNSCC patients of whom eight had tumor-positive surgical margins. The samples were analyzed with hLy-6D qRT-PCR, and the data were analyzed in relation to the clinicohistological parameters. A significant difference was shown between the group of patients with histopathological tumor-positive surgical margins and the non-cancer control group (p < 0.001), and the group of patients with histopathological tumor-free surgical margins (p = 0.001). This study shows a novel approach for molecular analysis of deep surgical margins in head and neck cancer surgery. The preliminary data of this approach for detection of MRC in deep margins of HNSCC patients are promising.

Effect of Early Individualized Dietary Counseling on Weight Loss, Complications, and Length of Hospital Stay in Patients With Head and Neck Cancer: A Comparative Study.

Patients with head and neck cancer (HNC) are at risk for undernutrition. Dietary counseling during treatment has positive effects on nutritional status and quality of life, however, the effects of dietary counseling started before initiation of treatment are currently unknown. Therefore we assessed the effect of early individualized dietary counseling (DC) on weight loss, major complications, and length of hospital stay (LOS) in patients with HNC. Ninety-five newly diagnosed HNC patients with (risk of) undernutrition receiving DC were compared to 95 matched HNC patients receiving usual nutritional care (UC). Difference in weight change over time was analyzed by generalized estimating equations (GEE). Differences in complications and LOS were studied by Pearson chi-squared and students t-tests. Weight change between diagnosis and end of treatment was −6.0 ± 6.9% (DC) and −5.4 ± 5.7% (UC; GEE: −0.4kg, 95% confidence interval: −1.2 to 0.5; P = 0.44). Less DC patients experienced overall postoperative complications (44%/70%, P = 0.04). No effect on major postoperative or (chemo)radiotherapy complications or LOS was found. This study showed a lower prevalence of overall postoperative complications in HNC patients receiving DC but could not demonstrate an effect on weight loss, other complications, and LOS.

Molecular diagnosis of minimal residual disease in head and neck cancer patients.

AimLocoregional recurrences and distant metastases in adequately treated head and neck squamous cell carcinoma (HNSCC) patients have a dismal effect on survival. Tumor cells that escape histopathological detection might be the prime cause of this effect. We evaluated whether minimal residual cancer (MRC) in deep surgical margins and disseminated tumor cells (DTCs) in bone marrow aspirates are associated with clinicohistopathological parameters and outcome.MethodsSubmucosal samples of deep resection margins of 105 HNSCC patients with histopathologically tumor-free surgical margins were analysed for the presence of MRC using hLy-6D qRT-PCR. Bone-marrow aspirates of 76 of these patients were analysed for DTCs by immunocytochemical staining. Presence of molecular-positive deep surgical margins, presence of DTC in bone marrow aspirates, and clinicohistopathological parameters were tested for associations with survival parameters by univariate and multivariate analyses.ResultsIn addition to lymph node stage, it appeared that vasoinvasive growth and particularly infiltrative growth pattern are significant predictors for locoregional recurrence (p = 0.041 and p = 0.006, respectively) and disease–free survival (p = 0.014 and p = 0.008, respectively). Remarkably, neither the presence of molecular-positive deep surgical margins nor that of DTC in bone marrow aspirates were significantly related to outcome.ConclusionsThe presence of vasoinvasive and infiltrative growth in HNSCC tumor specimens are significant risk-factors for locoregional recurrence and disease-free survival. At present there seems no role for molecular analysis of deep surgical margins and bone marrow aspirates in predicting outcome with the methods used.

Evaluation of vascular features of vocal cords proposed by the European Laryngological Society

A newly proposed classification by the European Laryngological Society (ELS) of glottic lesions by narrow-band imaging (NBI) divides their vascular patterns into longitudinal and perpendicular ones. The latter are further subdivided into the wide and narrow patterns. The longitudinal, wide, and narrow patterns are characteristic of benign disease, papilloma, and malignancy, respectively. The aim of the study was to investigate the diagnostic effectiveness of the classification. Forty patients with glottic lesions underwent microlaryngoscopy. The vascular patterns of all vocal cords were defined with NBI. The affected vocal cords were histologically analysed and comprised the arm (A). Unaffected vocal cords were not histologically analysed but followed-up and comprised the arm (B) and were regarded as true negatives if no suspicious changes appeared during the follow-up. The vocal cords from the arm A were categorised into the benign and malignant group according to the histologic result. The ratio of vascular patterns was determined and the groups were statistically compared using the Chi-square test and Fisher’s exact test. Perpendicular changes were observed in 36.6% (9/26) of benign diseases and in 100% (23/23) of cancer conditions (p < 0.001). Wide perpendicular changes appeared only in papillomas (6/6) while narrow ones mostly in malignancies (23/26) and also in benign conditions (3/26) (p < 0.001). The sensitivity, specificity, positive and negative predictive values, and accuracy were 100, 95, 88, 100 and 96%, respectively. The new ELS classification can be used effectively and safely to differentiate malignant from benign disease.

The influence of closure technique in total laryngectomy on the development of a pseudo-diverticulum and dysphagia

ObjectiveIn total laryngectomy, the neopharynx can be closed in several ways. It is suggested that a pseudo-diverticulum is seen more frequently in patients closed with vertical closure than with “T”-shaped closure, causing postoperative dysphagia. We report the results of patients treated with vertical closure and “T”-shaped closure with regard to the formation of a pseudo-diverticulum and postoperative dysphagia.MethodsIn our retrospective cohort study, we identified 117 consecutive laryngectomized patients treated in the VU University Medical Center of Amsterdam between March 2009 and December 2013. Evaluations with statistical analysis of postoperative outcome measures (the formation of a pseudo-diverticulum and dysphagia), qualitative and quantitative variables were conducted.ResultsPatient demographics were similar between the vertical-shaped closure and the “T”-shaped closure groups. In 84.6% of patients with vertical closure, a pseudo-diverticulum was seen compared to 18.5% with “T”-shaped closure (p < 0.001). Dysphagia was increasingly seen in patients with a pseudo-diverticulum (60.5%) compared to patients without a pseudo-diverticulum (39.5%) (p = 0.090).ConclusionFormation of a pseudo-diverticulum is more frequently seen in laryngectomy patients closed with vertical closure than in patients closed with “T”-shaped closure of the neopharynx. It is favorable to implement “T”-shaped closure in laryngectomy.

Costs from a healthcare and societal perspective among cancer patients after total laryngectomy: are they related to patient activation?

PurposeThe aim of this study is to investigate the associations between patient activation and total costs in cancer patients treated with total laryngectomy (TL).MethodsAll members of the Dutch Patients’ Association for Laryngectomees were asked to participate in this cross-sectional study. TL patients who wanted to participate were asked to complete a survey. Costs were measured using the medical consumption and productivity cost questionnaire and patient activation using the Patient Activation Measure (PAM). Sociodemographic and clinical characteristics were self-reported, and health status measured using the EQ-5D. The difference in total costs from a healthcare and societal perspective among four groups with different PAM levels were compared using (multiple) regression analyses (5000 bootstrap replications).ResultsIn total, 248 TL patients participated. Patients with a higher (better) PAM (levels 2, 3, and 4) had a probability of 70, 80, and 93% that total costs from a healthcare perspective were lower than in patients with the lowest PAM level (difference €−375 to €−936). From a societal perspective, this was 73, 87, and 82% (difference €−468 to €−719). After adjustment for time since TL, education, and sex, the probability that total costs were lower in patients with a higher PAM level compared to patients with the lowest PAM level changed to 62–91% (healthcare) and 63–92% (societal). After additional adjustment for health status, the probability to be less costly changed to 35–71% (healthcare) and 31–48% (societal).ConclusionsA better patient activation is likely to be associated with lower total costs from a healthcare and societal perspective.

A clinicopathological study and prognostic factor analysis of 177 salivary duct carcinoma patients from The Netherlands

Salivary duct carcinoma (SDC) is a subtype of salivary gland cancer with a dismal prognosis and a need for better prognostication and novel treatments. The aim of this national cohort study was to investigate clinical outcome, prognostic factors, androgen receptor (AR) and human epidermal growth factor receptor 2 (HER2) expression. SDC patients diagnosed between 1990 and 2014 were identified by the Nationwide Network and Registry of Histo‐ and Cytopathology in the Netherlands (PALGA). Subsequently, medical records were evaluated and pathological diagnoses reviewed. Data were analyzed for overall survival (OS), disease‐free survival (DFS), distant metastasis‐free survival (DMFS) and prognostic factors. AR was evaluated by immunohistochemistry (IHC), HER2 by IHC and fluorescent in‐situ hybridization. A total of 177 patients were included. The median age was 65 years, 75% were male. At diagnosis, 68% presented with lymph node metastases and 6% with distant metastases. Median OS, DFS and DMFS were 51, 23 and 26 months, respectively. In patients presenting without distant metastases, the absolute number of positive lymph nodes was associated with poor OS and DMFS in a multivariable analysis. AR and HER2 were positive in 161/168 (96%) and 44/153 (29%) tumors, respectively, and were not prognostic factors. SDC has a dismal prognosis with primary lymph node involvement in the majority of patients. The absolute number of lymph node metastases was found to be the only prognostic factor for DMFS and OS. AR expression and—to a lesser extent—HER2 expression hold promise for systemic treatment in the metastatic and eventually adjuvant setting.Disclaimer/Complaints regulations If you believe that digital publication of certain material infringes any of your rights or (privacy) interests, please let the Library know, stating your reasons.
