Analysis of patients who decline treatment for squamous cell carcinoma of the head and neck: National perspective

Harmful impact of treatment refusal in T3-4M0 endolaryngeal squamous cell carcinoma candidates for total laryngectomy: A STROBE analysis

PURPOSE

To evaluate the consequences of treatment refusal in total laryngectomy (TL) candidates with T3-4M0 endolaryngeal squamous cell carcinoma (SCC).

MATERIALS AND METHODS

A retrospective observational study was conducted in an inception cohort of 576 isolated T3-4M0 endolaryngeal SCC candidates for TL consecutively managed between 1970 and 2019 in a French university teaching hospital. The main endpoint was survival time and cause of death in 2 groups. Group A, 4.5% of the cohort, consisted of 26 patients who declined any laryngeal treatment. Group B consisted of 550 patients who accepted TL. Accessory endpoints were causes of TL refusal and associated variables. The STROBE guideline was applied. The significance threshold was set at P<0.005.

RESULTS

One-and 3-year actuarial survival estimates increased significantly (P<0.0001) from 39% and 15% in group A, to 83% and 63% in group B, respectively. In group A, 92% of causes of death implicated index SCC progression, whereas in group B intercurrent disease, metachronous second primary, locoregional and/or metastatic SCC progression and postoperative complications accounted for 37%, 31%, 29%, and 2%, respectively. The actuarial survival estimates within group A increased significantly (P=0.0003) from 0% at 1-year in patients managed with isolated supportive care to 56% in patients managed with chemotherapy (reaching 0% at 5years). Reasons for TL refusal were fear of surgery, refusal of tracheostoma, loss of physiologic phonation, and certain comorbidities. Age and chronologic period correlated significantly with TL refusal. Median age decreased (P<0.001) from 69years in group A to 58 years in group B. Percentage TL refusal increased (P<0.0001) from 2% to 11% before and after start 1990, respectively.

CONCLUSION

The current study determined loss of survival with refusal of any laryngeal treatment including TL, noted benefit of chemotherapy associated to supportive care, and discussed the possible contribution of immunotherapy.

The Impact of Medicaid Expansion on Head and Neck Malignancies Presentation and Survival

OBJECTIVE

Under the Affordable Care Act (ACA), Medicaid expansion became effective in states that have adopted it. We aim to examine its impact on head and neck cancers.

METHODS

A retrospective study that utilizes the Surveillance, Epidemiology, and End Results database, 2010-2016. Study population included patients with head and neck squamous cell carcinoma (HNSCC), differentiated thyroid carcinoma, and head and neck cutaneous melanoma. The objective is to examine disease-specific survival before and after Medicaid expansion.

RESULTS

In states that adopted Medicaid expansion, the ratio of Medicaid: uninsured patients increased from 3:1 to 9:1 (p < 0.001). In states that did not adopt Medicaid expansion, the ratio increased from 1:1 to 2:1 (p < 0.001), making the increase in Medicaid coverage in states that adopted the expansion significantly higher (p < 0.001). Patients diagnosed with HNSCC before the expansion had worse survival (hazard ratio [HR]: 1.24, 95% confidence interval: 1.11, 1.39, p < 0.001) in states that adopted Medicaid expansion.

CONCLUSIONS

Early data indicate that implementation of ACA improved disease-specific survival of patients with HNSCC.

The impact of travel distance to treatment centre on oral tongue squamous cell carcinoma survival and recurrence

There have been no prior studies examining the effect of distance to the treatment centre on oral squamous cell carcinoma outcomes in Australia. The purpose of this study was to analyse the impact of travel distance on oral tongue squamous cell carcinoma (OTSCC) outcomes. This was a retrospective analysis of 243 patients who received surgical treatment ± adjuvant therapy between 2007 and 2016. The overall survival (OS), disease-specific survival (DSS), and freedom from loco-regional failure (FFLRF) survival analyses were conducted using Kaplan-Meier curves and a multivariate Cox proportional hazards model. A competing risk (CR) analysis was conducted. Patients living ≥200 km from the treatment centre, when compared with those living within 40 km, had worse OS (hazard ratio (HR) 3.11, 95% confidence interval (CI) 1.74-5.54), DSS (HR 2.58, 95% CI 1.30-5.12), and FFLRF (HR 2.47, 95% CI 1.22-5.01). These discrepancies were significant when adjusted for socioeconomic status (OS P < 0.001, DSS P  0.004, FFLRF P = 0.005) and in the presence of CR (OTSCC-specific death with CR 'non-disease-related death' P =0.030, FFLRF with CR 'any cause death' P = 0.013, FFLRF with CR 'OTSCC-specific death' P = 0.004). Patients with OTSCC living ≥200 km from the treatment centre were found to have worse outcomes than those living within 40 km.

Survival analysis of patients with advanced hypopharyngeal cancer comparing patients who received primary surgery to those who received chemoradiation: An analysis of the NCDB

INTRODUCTION

The objective of this study was to use the American College of Surgeons' National Cancer Database (NCDB) to examine the association between primary treatment and overall survival (OS) among patients with locoregionally advanced hypopharyngeal cancer.

METHODS

6,055 adult patients diagnosed between 2004 and 2015 with stage III or IV, M0, hypopharyngeal squamous cell carcinoma were identified within the NCDB. Patients who received primary chemoradiation (CRT) were compared to those that received surgery with adjuvant radiation or chemoradiation (S + Adj). OS was compared between treatment groups using Kaplan-Meier analyses, propensity score adjustment, and Cox regression analyses.

RESULTS

The median survival was 22.7 months (IQR 11.0-49.0). The S + Adj group had a significantly higher comorbidity score, higher grade disease, and more advanced stage disease than the CRT group. S + Adj was associated with significantly improved survival when compared to CRT (p < 0.0001). A propensity score adjusting for facility type, facility location, care at multiple facilities, histology, and T stage was developed. S + Adj was associated with longer survival (HR: 0.72, 95% CI: 0.64-0.80) when compared to CRT in a multivariable Cox regression analysis (adjusting for age, race and ethnicity, insurance status, a comorbidity index, diagnosis year, treatment delay, N stage, and the propensity score). S + Adj was associated with significantly improved survival among those with T2 disease (p = 0.02), T3 disease (p = 0.02), and T4 disease (p < 0.0001) in sensitivity analyses examining these subcohorts independently.

CONCLUSIONS

Among patients with advanced hypopharyngeal cancer reported in NCDB, treatment with S + Adj was associated with longer survival compared to those treated with primary CRT.

Head and Neck Cancer Treatments from Chemotherapy to Magnetic Systems: Perspectives and Challenges

BACKGROUND

Cancer is one of the diseases causing society's fears as a stigma of death and pain. Head and Neck Squamous Cell Carcinoma (HNSCC) is a group of malignant neoplasms of different locations in this region of the human body. It is one of the leading causes of morbidity and mortality in Brazil, because these malignant neoplasias, in most cases, are diagnosed in late phases. Surgical excision, chemotherapy and radiotherapy encompass the forefront of antineoplastic therapy; however, the numerous side effects associated with these therapeutic modalities are well known. Some treatments present enough potential to help or replace conventional treatments, such as Magnetic Hyperthermia and Photodynamic Therapy. Such approaches require the development of new materials at the nanoscale, able to carry out the loading of their active components while presenting characteristics of biocompatibility mandatory for biomedical applications.

OBJECTIVE

This work aims to make a bibliographical review of HNSCC treatments. Recent techniques proven effective in other types of cancer were highlighted and raised discussion and reflections on current methods and possibilities of enhancing the treatment of HNSCC.

METHOD

The study was based on a bibliometric research between the years 2008 and 2019 using the following keywords: Cancer, Head and Neck Cancer, Chemotherapy, Radiotherapy, Photodynamic Therapy, and Hyperthermia.

RESULTS

A total of 5.151.725 articles were found, 3.712.670 about cancer, 175.470 on Head and Neck Cancer, 398.736 on Radiotherapy, 760.497 on Chemotherapy, 53.830 on Hyperthermia, and 50.522 on Photodynamic Therapy.

CONCLUSION

The analysis shows that there is still much room for expanding research, especially for alternative therapies since most of the studies still focus on conventional treatments and on the quest to overcome their side effects. The scientific community needs to keep looking for more effective therapies generating fewer side effects for the patient. Currently, the so-called alternative therapies are being used in combination with the conventional ones, but the association of these new therapies shows great potential, in other types of cancer, to improve the treatment efficacy.
