Tobacco and alcohol use after head and neck cancer treatment: influence of the type of oncological treatment employed

Carnosic acid: an effective phenolic diterpenoid for prevention and management of cancers via targeting multiple signaling pathways

Cancer is a serious global public health issue, and a great deal of research has been made to treat cancer. Of these, discovery of promising compounds that effectively fight cancer always has been the main point of interest in pharmaceutical research. Carnosic acid (CA) is a phenolic diterpenoid compound widely present in Lamiaceae plants such as Rosemary (Rosmarinus officinalis L.). In recent years, there has been increasing evidence that CA has significant anti-cancer activity, such as leukaemia, colorectal cancer, breast cancer, lung cancer, liver cancer, pancreatic cancer, stomach cancer, lymphoma, prostate cancer, oral cancer, etc. The potential mechanisms involved by CA, including inhibiting cell proliferation, inhibiting metastasis, inducing cell apoptosis, stimulating autophagy, regulating the immune system, reducing inflammation, regulating the gut microbiota, and enhancing the effects of other anti-cancer drugs. This article reviews the biosynthesis, pharmacokinetics and metabolism, safety and toxicity, as well as the molecular mechanisms and signaling pathways of the anticancer activity of CA. This will contribute to the development of CA or CA-containing functional foods for the prevention and treatment of cancer, providing important advances in the advancement of cancer treatment strategies.

Latin American Consensus on the Treatment of Head and Neck Cancer

Head and neck squamous cell carcinoma (HNSCC) is well known as a serious health problem worldwide, especially in low-income countries or those with limited resources, such as most countries in Latin America. International guidelines cannot always be applied to a population from a large region with specific conditions. This study established a Latin American guideline for care of patients with head and neck cancer and presented evidence of HNSCC management considering availability and oncologic benefit. A panel composed of 41 head and neck cancer experts systematically worked according to a modified Delphi process on (1) document compilation of evidence-based answers to different questions contextualized by resource availability and oncologic benefit regarding Latin America (region of limited resources and/or without access to all necessary health care system infrastructure), (2) revision of the answers and the classification of levels of evidence and degrees of recommendations of all recommendations, (3) validation of the consensus through two rounds of online surveys, and (4) manuscript composition. The consensus consists of 12 sections: Head and neck cancer staging, Histopathologic evaluation of head and neck cancer, Head and neck surgery-oral cavity, Clinical oncology-oral cavity, Head and neck surgery-oropharynx, Clinical oncology-oropharynx, Head and neck surgery-larynx, Head and neck surgery-larynx/hypopharynx, Clinical oncology-larynx/hypopharynx, Clinical oncology-recurrent and metastatic head and neck cancer, Head and neck surgery-reconstruction and rehabilitation, and Radiation therapy. The present consensus established 48 recommendations on HNSCC patient care considering the availability of resources and focusing on oncologic benefit. These recommendations could also be used to formulate strategies in other regions like Latin America countries.

Prognostic Value of Hematological Parameters in Oral Squamous Cell Carcinoma

INTRODUCTION

Oral squamous cell carcinoma (OSCC) remains a significant public health concern. The variables utilized to determine appropriate treatment for this disease also represent its most unfavorable prognostic factors, with these parameters solely determined by the neoplasm and its behavior. However, a lack of well-established indices is evident in the literature that specifically relate to the patient and indicate a worse prognosis.

OBJECTIVE

To assess the prognostic impact of hematological indices in patients with OSCC.

METHODS

This retrospective cohort study included patients with oral squamous cell carcinoma (OSCC) who underwent curative-intent treatment. Treatment encompassed surgery, followed by adjuvant therapy, as necessary. Laboratory tests were conducted immediately prior to surgery, and demographic information was obtained from medical records.

RESULTS

The cohort comprised 600 patients, with 73.5% being male subjects. Adjuvant treatment was recommended for 60.3% of patients. Throughout the follow-up period, 48.8% of participants died. Univariate analysis indicated that perineural invasion, angiolymphatic invasion, pT4 tumors, lymph node metastases, extranodal extravasation, RDW > 14.3%, NLR (neutrophil-lymphocyte ratio) > 3.38, PLR (platelet-lymphocyte ratio) > 167.3, and SII (systemic inflammatory/immune response index) > 416.1 were factors associated with increased mortality. These threshold values were established through ROC curve analysis. In the multivariate analysis, angiolymphatic invasion (HR = 1.43; 95% CI: 1.076-1.925; p = 0.014), pT4a/b tumors (HR = 1.761; 95% CI: 1.327-2.337; p < 0.001), extranodal extravasation (HR = 1.420; 95% CI: 1.047-1.926; p = 0.024), and RDW (HR = 1.541; 95% CI: 1.153-2.056; p = 0.003) were identified as independent risk factors for decreased overall survival.

CONCLUSIONS

RDW > 14.3% was proven to be a reliable parameter for assessing overall survival in patients with OSCC. Further studies are required to evaluate the clinical applicability of other hematological indices.

Continued tobacco use among tobacco-related head and neck cancer patients seeking care in a tertiary care facility, South India

INTRODUCTION

Continued tobacco use in cancer patients leads to decreased treatment efficacy and safety, decreased survival, decreased quality of life, and an increased risk of cancer recurrence and primary tumours at other sites.

OBJECTIVE

To determine the prevalence of continued tobacco usage during the first 6 months of diagnosis among tobacco-related head and neck cancer patients seeking care from a tertiary care centre and the factors associated with it.

METHODS

A facility-based cohort study was conducted at a tertiary care centre in Puducherry, India. Newly diagnosed head and neck cancer patients aged > 18 years with a history of tobacco use were interviewed to gather information on their socio-demographic, clinical characteristics, and tobacco usage. All participants were interviewed again at the 3rd month and at the 6th month during their follow-up visit. The data were entered in EpiData v3.1 and analysed using STATA v14. Multivariable logistic regression analysis was done with continued tobacco use as the dependent variable and variables that were found significantly associated with continued tobacco use in univariate analysis.

RESULTS

Out of 220 study participants at baseline, 157(71 %; 95 % CI: 65.1-77.1) were using tobacco at the time of diagnosis. Out of these 157 participants, 80(50.9 %; 95 % CI; 43.1-58.7) continued to use tobacco at the 3rd month, 63(40.1 %: 95 % CI: 32.6-47.9) continued to use tobacco at the 6th month. The characteristics significantly associated with continued tobacco use are age (less than 39 years and more than 70 years), primary school education, nuclear family, and living alone, smoking tobacco, and increased duration of tobacco use.

CONCLUSION

Two-fifths of head and neck cancer patients with a history of tobacco use continued to use tobacco at the 6th month after diagnosis of cancer. Awareness of effects of tobacco use and the benefits of tobacco cessation needs to be created among cancer patients.

Management of Stage III Oral Cavity Squamous Cell Carcinoma in Light of the New Staging System: a Critical Review

PURPOSE OF REVIEW

Oral squamous cell carcinoma (OSCC) patients have a poor prognosis, especially in advanced stages. AJCC/UICC staging system 8th edition (TNM8) included depth of invasion (DOI) as part of T staging and stage III has become a heterogeneous group of lesions, composed of patients with larger DOI and/or width. Additionally, stage III includes N1, regardless of the primary tumor width or DOI. The real prognostic value of each of these characteristics and the need for adjuvant treatment for stage III patients is not well established.

RECENT FINDINGS

TNM8 stratified OSCC into prognostic groups based on overall survival. Extranodal extension, positive or close margins, pT3 or pT4 tumors, pN2 or pN3 nodal disease, nodal disease in levels IV or V, perineural invasion, vascular invasion, and lymphatic invasion are the main adverse features for OSCC, and adjuvant treatment is largely recommended for these patients. Stage III patients should be addressed with caution. So far, there is no significant evidence for recommending or excluding adjuvant treatment for stage III OSCC without adverse features. The authors largely recommend adjuvant radiotherapy for these cases, especially because pT3 without adverse features is rare. Further studies on this topic are necessary.

Nutritional and immunological parameters as prognostic factors in patients with advanced oral cancer

OBJECTIVE

The aim of the present study was to analyze the prognostic relationship of weight loss and preoperative hematological indexes in patients surgically treated for pT4a squamous cell carcinoma of the oral cavity.

METHODS

A retrospective cohort study.

RESULTS

Percent weight loss greater than 10% was identified in 49 patients (28.2%), and any weight loss in relation to the usual weight occurred in 140 patients (78.7%). Percent weight loss greater than 10% (HR = 1.679), Red cell distribution width (RDW) values greater than 14.3% (HR = 2.210) and extracapsular spread (HR = 1.677) were independent variables associated with risk of death.

CONCLUSION

Patients with advanced squamous cell carcinoma of the oral cavity present significant weight loss and as significantly immunocompromised. Increased values of RDW and higher percentages of weight loss in relation to the individual's usual weight, together with extracapsular spread of metastatic lymph nodes, were risk factors for lower survival, regardless of other clinical and anatomopathological characteristics.

Considerations for developing supportive care interventions for survivors of head and neck cancer: A qualitative study

OBJECTIVE

This study aimed to describe considerations for developing supportive care interventions targeted to head and neck cancer (HNC) survivors.

METHODS

One-time semi-structured interviews (N = 33) were conducted with HNC survivors who had recently finished treatment (n = 20) and HNC providers (e.g., physicians, nurses; n = 13). Interviews were transcribed verbatim and coded using inductive applied thematic analysis techniques to identify themes.

RESULTS

HNC survivors (75% male; M = 61 years old) and providers (54% physicians; 62% female) were unanimously supportive of developing HNC-specific supportive care interventions. Participants described potential benefits of offering interventions at various points throughout the HNC treatment and survivorship trajectory rather than at a single critical time. Many participants preferred group-based interventions because of the high value of peer-support. Others described how group interventions may not be appropriate for all HNC survivors due to risks for negative social comparisons and exacerbated anxiety. Participants suggested topics that should be addressed in HNC-specific interventions including education about acute and long-term side effects, symptom management, nutritional support, relationship/social role changes, grief/loss, and fear of recurrence.

CONCLUSIONS

HNC-specific supportive care interventions are critically needed, as survivors experience persistent symptoms and distinct psychosocial concerns that impact quality of life. Findings from this study can inform the development of supportive care interventions targeted to the unique psychosocial concerns of HNC survivors.

"I have cancer during COVID; that's a special category": a qualitative study of head and neck cancer patient and provider experiences during the COVID-19 pandemic

PURPOSE

The COVID-19 pandemic has drastically changed cancer care delivery strategies. Patients with locally advanced head and neck cancer (LA-HNC) may be particularly affected by the COVID-19 pandemic, as they often undergo treatments that require daily clinic visits (e.g., radiation therapy). The goal of this study was to characterize the lived experience of LA-HNC patients and their healthcare providers during the COVID-19 pandemic.

METHODS

LA-HNC patients who completed a full course of chemotherapy and radiation therapy during the COVID19 pandemic (N = 20) and LA-HNC healthcare providers (N = 13) participated in semi-structured interviews. Interviews were audio-recorded, transcribed verbatim, and analyzed for qualitative themes.

RESULTS

The COVID-19 pandemic had a significant impact on patients' overall quality of life and health care. Results were organized in four main themes: (1) increased psychological distress; (2) exacerbated social isolation; (3) added stress in clinic for patients and providers; and (4) delays in health care.

CONCLUSIONS

Findings highlight myriad ways LA-HNC patients and providers have been affected by the COVID-19 pandemic. Results can inform the development of supportive interventions to assist LA-HNC in managing COVID-19-related stress and unmet needs related to social isolation and in-clinic support.

Smoking Cessation after a Cancer Diagnosis: A Cross-Sectional Analysis in the Setting of a Developing Country

Since smoking accounts for around 30% of all cancer deaths, public health campaigns often focus on smoking cessation as a means of primary prevention. However, smoking after cancer diagnosis is also associated with a higher symptom burden and lower survival rate. As data regarding smoking cessation vary dramatically between different populations, we aimed to analyze smoking prevalence in cancer patients, smoking cessation after cancer diagnosis, and the factors associated with smoking cessation in the setting of a developing country. We performed a cross-sectional survey on 695 patients in two clinical hospital centers. After cancer diagnosis, 15.6% of cancer patients stopped smoking. Male gender, younger age, and smoking-related cancer were the main factors associated with greater smoking cessation (p < 0.05). A total of 96% of breast cancer patients continued to smoke after cancer diagnosis and, compared to lung and colorectal cancer patients, exhibited a lower reduction in the number of cigarettes smoked (p = 0.023). An alarming rate of smoking prevalence was recorded in younger patients (45.6% at the time of cancer diagnosis) suggesting a future rise in smoking-related cancers and complications. These results should guide anti-smoking public health campaigns in transitional countries with a critical focus on younger and breast cancer patients.

Squamous cell carcinoma of head and neck: what internists should know

Squamous cell carcinoma of head and neck (SCCHN) is a group of cancer arising from mucosal surfaces of the head and neck. Optimal management of SCCHN requires a multidisciplinary team of surgical oncologists, radiation oncologists, medical oncologists, nutritionist, and speech-language pathologists, due to the complexity of anatomical structure and importance of functional outcome. Human papilloma virus (HPV)-related SCCHN represents a distinct subset from HPV negative SCCHN which is associated with carcinogen exposure such as cigarette smoking, betel nut use and alcohol. HPV related SCCHN responds better to concurrent chemoradiation and has better overall prognosis, compared to HPV negative SCCHN. Radiation therapy has been introduced to the treatment of SCCHN, administered concurrently with systemic chemotherapy for locoregional SCCHN, as well as a palliative measure for recurrent and/or metastatic (R/M) SCCHN. Recently, immune checkpoint inhibitors have been shown to improve overall survival in R/M-SCCHN and have been incorporated into the standard of care. Combination approaches with immune therapy and targeted therapy for biomarker enriched population based on genomics are being actively investigated and will shape the future of SCCHN treatment.

Relapse of Tobacco Consumption in Patients Treated for Head and Neck Cancer: a Cross Sectional Study

Head and neck cancers are a major healthcare burden in the Indian Subcontinent mainly due to tobacco consumption. While advances in treatment have resulted in better control rates and survival, relapse of tobacco consumption contributes to recurrences. The authors embarked upon a cross-sectional questionnaire-based study to assess the burden of tobacco relapse along with factors resulting into relapse. Patients on follow-up after treatment of tobacco-related head and neck cancers in a dedicated cancer institute were included in the study. Demographic data was noted, and responses were obtained on a five-point Likert's scale for reasons of relapse which were analyzed with a median and interquartile range. Predictors of relapse were assessed using multivariate logistic regression analysis. In our sample size of 500, relapse rate was 15%, majority of which occurred in the first year of follow-up when disease was loco-regionally controlled. Most common causative factor for relapse was lower motivation to quit. Care givers must incorporate tobacco cessation counseling as an integral part of head and neck cancer treatment.

Psychosocial Issues in Patients with Head and Neck Cancer: an Updated Review with a Focus on Clinical Interventions

PURPOSE OF REVIEW

There are frequent and diverse psychosocial issues that afflict patients with head and neck cancer (HNC) across the illness trajectory, prompting a focus on clinical interventions to prevent and mitigate psychosocial distress. We sought to characterize current understanding on the cause, effects, and interplay of various psychosocial factors in HNC and summarize updated, evidence-based interventions.

RECENT FINDINGS

The psychosocial experience of patients with HNC is characterized by a disproportionately high incidence of depression, suicide, continued substance dependence/abuse, and distress related to relationship conflict, social isolation, disfigurement, and damage to self-image. As we move towards a more thorough understanding and greater appreciation of the relationship between HNC and patient quality of life (QoL), future research focuses on implementation of effective, accessible clinical interventions to alleviate psychosocial distress in this population.

Informational and Support Needs of Patients with Head and Neck Cancer: Current Status and Emerging Issues

The objective of this article is to review and summarize the extant literature on head and neck cancer (HNC) patients’ informational needs and to characterize emerging issues in this patient population in order to define priorities for future research. HNC patients may undergo challenging treatment regimens and experience treatment-related alterations in primary daily functions such as speech and eating. These changes often persist following treatment and may lead to significant deficits in quality of life and interpersonal relations. Despite empirical evidence demonstrating that receipt of adequate information and support is predictive of improved outcomes post-treatment, relatively limited attention has been paid to the informational and support needs of HNC patients. This review focuses primarily on three topic domains: (1) managing treatment-related side effects; (2) addressing alcohol and tobacco dependence; and (3) informational needs in the areas of human papillomavirus (HPV) and clinical trials. While there is increasing awareness of the rehabilitation and survivorship needs in this patient population, patients note that the impact of treatment on social activities and interactions is under-discussed and of key concern. In addition, there is a significant gap in addressing communication and informational needs of caregivers and family members who are integral for promoting healthy behaviors and self-care post-treatment. Greater integration of programs that address tobacco or alcohol dependency within a comprehensive treatment and support plan may increase patient motivation to seek help and enhance patient success in maintaining long-term abstinence. Finally, emerging patient-provider communication needs, particularly in the context of decision making about clinical trials or surrounding an HPV-related diagnosis, have been noted among both patients and healthcare providers. Future research on the development of novel programs that offer feasible and acceptable methods for addressing unmet informational and support needs is warranted and may yield benefit for improving patient-reported outcomes.

Complete pathologic response as a prognostic factor for squamous cell carcinoma of the oropharynx post-chemoradiotherapy

Introduction

Chemoradiotherapy for squamous cell carcinoma of the oropharynx (SCCO) provides good results for locoregional disease control, with high rates of complete clinical and pathologic responses, mainly in the neck.

Objective

To determine whether complete pathologic response after chemoradiotherapy is related to the prognosis of patients with SCCO.

Methods

Data were prospectively extracted from clinical records of N2 and N3 SCCO patients submitted to a planned neck dissection after chemoradiotherapy.

Results

A total of 19 patients were evaluated. Half of patients obtained complete pathologic response in the neck. Distant or locoregional recurrence occurred in approximately 42% of patients, and 26% died. Statistical analysis showed an association between complete pathologic response and lower disease recurrence rate (77.8% vs. 20.8%; p = 0.017) and greater overall survival (88.9% vs. 23.3%; p = 0.049).

Conclusion

The presence of a complete pathologic response after chemoradiotherapy positively influences the prognosis of patients with SCCO.

Nicotine dependence and smoking habits in patients with head and neck cancer

OBJECTIVE

To assess smoking habits and nicotine dependence (ND) in patients with head and neck cancer Methods: This study involved 71 smokers or former smokers with squamous cell carcinoma in the oral cavity, pharynx, or larynx who were treated at a university hospital in the city of São Paulo between January and May of 2010. We used the Fagerström Test for Nicotine Dependence to evaluate smoking habits and ND in the sample. Data regarding cancer treatment were collected from medical records. Depending on the variables studied, we used the chi-square test, Fisher's exact test, Student's t-test, or Spearman's correlation test.

RESULTS

Of the 71 patients, 47 (66.2%) presented with high or very high ND, 40 (56.3%) smoked more than 20 cigarettes/day, and 32 (45.1%) smoked their first cigarette within 5 min of awakening. Advanced disease stage correlated significantly with the number of cigarettes smoked per day (p = 0.011) and with smoking history (p = 0.047). We found that ND did not correlate significantly with gender, disease stage, smoking cessation, or number of smoking cessation attempts, nor did the number of cigarettes smoked per day correlate with smoking cessation or gender. Treatment for smoking cessation was not routinely offered.

CONCLUSIONS

In most of the patients studied, the level of ND was high or very high. The prevalence of heavy smoking for long periods was high in our sample. A diagnosis of cancer is a motivating factor for smoking cessation. However, intensive smoking cessation treatment is not routinely offered to smoking patients diagnosed with cancer.

Indicators of psychiatric disorders in different oncology specialties: a prevalence study

Objective. This study evaluated the prevalence of various indicators of psychiatric disorders in Brazilian outpatients with cancer and assessed possible associations with sociodemographic indicators. Materials and Methods. A total of 1,385 patients were evaluated using the following instruments: Patient Health Questionnaire-4 (PHQ-4), Generalized Anxiety Disorder (GAD-7), Fagerström Test for Nicotine Dependence (FTND), and Fast Alcohol Screening Test (FAST). Results. The sample was composed of both genders with a slight predominance of women (55.8%), subjects with incomplete/completed elementary school (59%), married (67.4%), with children (94%), not active from a labor viewpoint (61.6%), and following some type of religion (79.5%). The prevalence of anxiety for the total sample varied between 21.5 and 27.4%. The prevalence of depression was 21.1%, tobacco abuse/dependence was 40.2%, and alcohol was 20.3%. Women had significantly higher levels of anxiety and depression than men. Men had higher levels of substance abuse/dependence indicators than women. Conclusion. These results are consistent with the literature, which attests to the high prevalence of psychiatric disorder indicators in cancer patients, especially compared to the general population.

Modifiable risk behaviors in patients with head and neck cancer

BACKGROUND

Use of tobacco products, excessive alcohol consumption, and high-risk sexual behaviors increase the risk of developing head and neck cancer and impacts treatment effectiveness after diagnosis. This study examined smoking and engagement in other modifiable behavioral risk factors and human papillomavirus (HPV) status in patients with head and neck cancer in order to facilitate identification and foster development of targeted interventions in high-risk patients.

METHODS

Participants were 102 patients with head and neck cancer at a large urban cancer center who completed a self-report background and health questionnaire and provided a saliva sample for determination of the long-acting nicotine metabolite cotinine.

RESULTS

Compared with former and never-smokers, current smokers were less educated, less likely to be married or living with a partner, and consumed more alcohol. Cotinine analysis indicated that 4 of 16 (25%) patients who denied past-month cigarette use misrepresented their true smoking status. Of patients with oropharyngeal cancer, 74% were confirmed as HPV-positive, and compared with HPV-negative patients, they were younger, more likely to be married/partnered and of Caucasian race, and reported more past vaginal and oral sexual partners. Only one-third of HPV-positive patients were aware of their HPV disease status.

CONCLUSIONS

Cigarette smoking is associated with engagement in other modifiable risk factors in patients with head and neck cancer. Self-report measures of smoking may not accurately depict true smoking status. HPV-positive cancer patients were more likely to endorse a history of multiple sexual partners. Regular screening and targeted interventions for these distinct risk factors are warranted.

Head and neck cancer: causes, prevention and treatment

Although head and neck carcinoma ranks fifth among cancer types, patient survival rates have not changed significantly over the past years.

OBJECTIVE

To determine the risk factors, causes, therapies, and prevention measures for head and neck cancer.

METHOD

Risk factors, causes, therapies, and preventive measures for this disease were searched on databases PUBMED, MEDLINE, and SCIELO.

RESULTS

Alcohol and tobacco are still atop risk factors. Other factors may influence the development of head and neck carcinoma. Surgery is the main treatment option, and the addition of radiotherapy following surgery is frequent for patients in the early stages of the disease. Other therapies target specific genetic molecular components connected to tumor development. Disease preventive measures include smoking cessation, limiting alcohol intake, preventing exposure to tobacco smoke and environmental carcinogenic agents, early detection of infection by HPV, maintaining oral health, good eating habits, and managing stress.

CONCLUSION

Additional research is needed for a more thorough understanding of the development of head and neck carcinomas and to shed light on new ways to improve therapeutic approaches and interventions.
