Psychological disorders ( including depression and PTSD) and social withdrawal in laryngectomees

The loss of voice and a decrease in physical functioning due to breathing through a stoma are known to result in long-term changes in daily and professional life. There is growing evidence that head and neck cancer patients including laryngectomees are more often anxious and distressed than other cancer patients. Prevalence rates of psychiatric problems in laryngeal cancer patients vary from 20% to 60 %, if nicotine dependence is taken included. Studies reported depression in 4-20% of head and neck cancer patients, anxiety disorder and phobia in 2 - 6%,  adjustment disorder in 4 - 13%, post traumatic stress disorder (PTSD) in 1 -2% and alcohol dependence in 5-33%.

Several recent studies from the University of Leipzig in Germany explored the role of psychological problems in laryngectomees.

Psychological disorders were diagnosed in about a quarter of patients during the first year after laryngectomee according to a new study by Keszte et al. These were evenly distributed among males and females. However, women suffered more often from PTSD and generalized anxiety disorder. Alcohol dependency developed in 80% of the patients who had acquired no voice 80% following laryngectomy. Only 7% of individuals with any mental disorder received psychotherapy one year after laryngectomy. None of the patients diagnosed with alcohol dependency received psychotherapy or psychiatric treatment.

Another study by Danker et al. found that more than 40% of larngectomees withdrew from conversation. Only one-third of all laryngectomees regularly took part in social activities. About 87% perceived stigmatization because of their changed voice and more than 50% felt embarrassed because of their tracheostoma. Almost one-third of the patients had increased anxiety and depression.

These studies illustrates that only one in twelve patients who suffered from psychological disorders following laryngectomy receive adequate psychotherapeutic support. Because mental health seems to be related to successful voice restoration, more effort is needed to promote speech rehabilitation after laryngectomy.  Also more programs are needed to combat alcohol dependency. The studies also highlights the urgent need for psychological and social support programs for laryngeal cancer patients.

Long-term use of Heat-Moisture Exchangers (HMEs) among laryngectomees: medical, social and psychological patterns

A study published in 2013 by Brook et al. evaluated the long-term use of HMEs and other accessories by laryngectomized patient and especially on the use of the Provox® Micron.

 After laryngectomy, pulmonary protection is mostly acquired by means of using a Heat and Moisture Exchanger (HME) that is placed on an airtight seal around the stoma. The effects of HMEs on tracheal climate have been well-described, and the filtration effect of an HME with electrostatic filter has been described . 

This study investigated long-term use of HMEs in laryngectomees. A questionnaire was sent to 195 laryngectomees of which 75 were returned. Over 85% of all respondents used an HME, of which 77% were compliant users (i.e. >20 hrs/day). Incidence of pulmonary illnesses (either prior of post-surgery) was about 25%. Over 90% of all respondents were heavy smokers prior to their laryngectomy. One-third of all respondents are regularly exposed to dusty environments. Compliant HME-users tend to use less external humidifiers and vaporizers, showing a better pulmonary status and less health-care costs. Regarding Quality of Life, patients using a FreeHands device tended to have the most social contacts (r=.251; p=.030).The prevalence of depression is high, pointing to an urgent need to recognize and treat psychiatric problems like depression and suicidal ideation in this patient group.

Heartburn caused by gastric reflux is a risk factor for laryngopharyngeal cancer

Gastric reflux can reach the upper airway, inducing cellular damage in the epithelial lining. This may be a risk factor for development of laryngopharyngeal squamous cell carcinoma although the medical literature is inconclusive. Frequent heartburn caused by gastric reflux was found to increase the risk for development of throat cancer, and over-the-counter antacids medication may provide protection from it, according to a new study  published in the journal of Cancer Epidemiology, Biomarkers and Prevention.

Researchers from Brown University studied heartburn incidence and medication use in 631 patients with squamous cell cancers of the throat and vocal cords who were not heavy smokers or drinkers, matching them with 1,234 healthy controls.

The investigator found that individuals who had reported a history of frequent heartburn were 78% more likely to have cancer than those who did not. Those with frequent heartburn who took antacids reduced their risk for cancer by 41%, compared with those whose heartburn was not treated.

There was no reduced risk among those taking proton pump inhibitors (i. e., Prilosec, Nexium, Prevacid, Aciphex) or histamine H2 receptor antagonists (i.e., Pepcid, Tagamet, Zantac). However, this may be because those who took such medications were likely to have had severe acid reflux, and not because those drugs are ineffective. The authors recommended that further studies are needed to clarify the possible chemopreventive role of antacid use for patients with gastric reflux.

Michael Douglas shares his treatment experiences for throat cancer and its association with sexually transmitted HPV.

Michael Douglas underwent chemotherapy and radiation treatment in 2011 for stage four throat cancer. He described his difficult personal experiences on the road to recovery in a recent interview. Douglas was shaken when he was diagnosed with late-stage cancer in 2010 after it took his physicians nine months to make the diagnosis. In an interview with the Guardian newspaper, Michael Douglas said that the throat cancer he was diagnosed three years ago was associated with HPV human papillomavirus (HPV) which can be transmitted during oral sex. Through this revelation Douglas pushed the disease onto the mind of millions of Americans who may have become concerned about this cancer for the first time. 

His first symptoms were a sore tooth that resembled a dental infection. He was seen by a periodontist and an otolaryngologist who repeatedly gave him antibiotics without any effect on the pain. After the clinicians assured him that he is better he left to an overseas vacation and only upon his return did another physician discover a walnut-size tumor at the base of his tongue. A biopsy of the tumor lead to the diagnosis of a stage-four throat cancer.

Douglas immediately underwent a grueling eight-week program of chemotherapy and radiation. He was able to avoid a feeding tube but still lost 45 pounds in the process. During the radiation treatment, Douglas was too weak to move around, and stayed confined to a sofa at his home. He currently feels rejuvenated with a new lease on life and is be back at work making movies again.

The HPV Type 16, is also known to cause cervical cancer in women. Unfortunately there no early oral screening test for HPV such as the Pap test. The lack of a screening test for oral HPV means that a doctor should be seen as soon as symptoms appear: a lump in the neck, a sore throat or ear pain that persists for two weeks.

There are currently no studies showing that vaccines to prevent cervical cancer from HPV Types 16 and 18,  also prevent HPV related oral cancer. However, these vaccines are recommend for boys and young men.

Most head and neck cancers are caused by tobacco and alcohol. The overall number of cancer caused by tobacco and alcohol are decreasing, while those associated with HPV are increasing. The cancer caused by HPV generally occurs near the base of the tongue; a difficult site to see and test.  

A saliva test can detect an oral HPV infection. However it is not very helpful because 85% of individuals may be colonized with a variety of HPV types and less than 1% of individuals with HPV 16 eventually develop throat cancer.

Currently about a quarter of head and neck cancer are caused by HPV and it is associated with 80% of tonsillar cancer. About 25,000 cases a year are diagnosed in the United States, compared with 226,000 lung cancers. However, it is growing in importance as smoking-related oral cancers decline.Patients with  positive cancer associated with HPV have a lower risk of dying compared to those with HPV-negative cancer.

The growing frequency in oral sex may have contributed to the increase in cancer caused by HPV. Men are twice as likely as women to get it, and it is more common among whites than blacks. Straight men are more likely to get the cancer than gay men perhaps because there may be more HPV in vaginal fluid than on the penis.

Human papilloma virus (HPV) as a cause of laryngeal cancer: new treatment options.

HPV-related head and neck cancers occur mainly in the oropharynx ( tonsils and the back of the tongue ).  However, a 2013 study from China found HPV infection, especially infection due to the high-risk type HPV-16, was found to be significantly associated with the risk of laryngeal squamous cell carcinoma.

Knowing whether one’s cancer was caused by HPV may help physicians determine the patient prognosis and survival.  Head and neck cancers caused by HPV infection tend to respond better to current treatments as compared to head and neck cancers caused by tobacco or alcohol use.  There are also new treatment options available to patients whose cancers are caused by HPV . These include vaccine clinical trials and treatment protocols that use less radiation and chemotherapy. These are easier for the patient to tolerate as they may generate fewer side effects.

The only way that head and neck cancers can be evaluated for the presence of HPV is to biopsy the lesion and test it for the presence of HPV DNA.  Patients who have already completed surgery, for head and neck cancer, can find out if their cancer is HPV related if the pathology sample is still available.

Anaerobic and microaerophilic bacteria in the biofilm on voice prostheses

Voice rehabilitation with voice prostheses is a standard therapy in laryngectomized patients. Biofilm formation on the surface of the voice prostheses causes device failure and requires frequent replacements. Studies analyzing the biofilm of voice prostheses have mainly focused on fungi and aerobic bacteria. Anaerobic bacteria as an integral part of the biofilms on voice prostheses have not been investigated yet.

Betl et al of the Department of Periodontology, Bernhard Gottlieb School of Dentistry, Vienna, Austria,  performed aprospective pilot study on the occurrence of anaerobic and microaerophilic pathogens in biofilm formation on voice prostheses.

Biofilm samples of 15 voice prostheses were analyzed using a polymerase chain reaction-based hybridization method, searching for the existence of 11 selected anaerobic and microaerophilic pathogens.

In 80% of the voice prostheses, at least one and up to 10 of the tested bacteria were identified. Fusobacterium nucleatum was the most common isolate (73%). Other frequently occurring pathogens were Treponema denticola (40%), Tannerella forsythia (33%), and Eikenella corrodens (33%). There was no correlation between the number of identified bacteria and the indwelling times (mean, 127 days; maximum, 344 days; minimum, 22 days).

This is the first study showing the presence of anaerobic and microaerophilic potential pathogens as part of the biofilm formation on the surface of voice prostheses. Further studies are warranted to find out if these organisms may be responsible for accelerated biofilm formation and reduced lifetime of the voice prostheses.

Laryngectomy is performed more often in patients with advanced laryngeal cancer

Zhu and colleagues recently investigated whether having a medical comorbidity influenced the choice of treatment of patients with advanced squamous cell carcinoma of the larynx. Comorbidity is the presence of an underlying pathologic condition that has an impact on a patient's total burden of disease. More than 2/3 of patients with cancer have a comorbid condition, and up to one-third of these patients have 2 or more, with hypertension, cardiovascular disease, and pulmonary disease among the most prevalent.

The study evaluated 16 849 patients from more than 1400 medical centers diagnosed with primary invasive advanced squamous cell carcinoma of the larynx between 2003 and 2008. They were selected from the National Cancer Database.

The study demonstrated that receipt of treatment (chemoradiation vs total laryngectomy) was significantly associated with comorbidity. Patients with comorbidity were more likely to have subtotal or total laryngectomy. Patients were also more likely to undergo laryngectomy if they had stage IV disease and if they had been diagnosed at a teaching or research institution. Patients were more likely to receive chemoradiation if they were diagnosed after 2003 or if they lived in a zip code with a high percentage of high school graduates.

The study is the first that demonstrates that patients with advanced laryngeal cancer with one or more comorbidities are more likely to receive surgery than chemoradiation compared with patients without any comorbidity. Previous studies have demonstrated better survival in patients with advanced laryngeal cancer who had been treated with surgery compared with those without.

This study supports the superiority of laryngectomy even in presence of comorbidity.  Even though patients with a comorbidity were less healthy initially their outcome was better after laryngectomy than those who received chemoradiation.

A new study illustrates the safety and efficacy of transoral robotic surgery for supraglottic laryngectomy

Transoral, minimally invasive organ preservation surgeries are being increasingly used for treatment of laryngopharyngeal carcinomas to avoid the toxicities of combined chemotherapy and radiation therapy regimens. A study by Ozer and colleagues from Ohio Medical Center in Columbus investigated the efficacy, safety, and functional outcomes of transoral tobotic surgery (TORS) supraglotic laryngectomy.
The preliminary study examined the outcomes of 13 of head and neck cancer patients with tumors located in the supraglottic region which is the region of the throat between the base of the tongue and just above the vocal cord. The study found that the use of robot-assisted surgery to remove these tumors through the mouth took only about 25 minutes on average, and that blood loss was minimal - a little more than three teaspoons, or 15.4 milliliters, on average, per patient. No surgical complications were encountered and 11 of the 13 patients could receive oral diet within 24 hours. If, on the other hand, these tumors are removed by performing open surgery on the neck, the operation can take at least 4 hours to perform, require 7 to 10 days of hospitalization on average and require a tracheostomy tube and a stomach tube.The results were published recently in the journal Head and Neck. According to the authors The transoral robotic method enables shorter surgery, less time under anesthesia, a lower risk of complications and shorter hospital stays for these patients and no external surgical incisions for the patient.

Necrotizing fasciitis-a newly recognized complication of laryngectomy

Necrotizing fasciitis (NF) was recently recognized as a new post surgical complication of laryngectomy. NF is an unusual, life threatening, rapidly advancing serious infection characterized by widespread fascial and subcutaneous tissue necrosis and gangrene of the skin. It most commonly affects the extremities, abdominal wall and perineum, whereas cervical NF is rare. NF of the head and neck is often caused by both aerobic and anaerobic microorganisms found in the upper aerodigestive tract. Usually, cervical NF originates from odontogenic, tonsillar and pharyngeal infection, and it is very rarely a complication of surgical procedure. Without immediate surgical treatment, cervical NF leads to mediastinitis and fatal sepsis. There was only one case of cervical NF after total laryngectomy described in the literature. Hadzibegovic and colleagues recently reported two additional cases of cervical NF after total laryngectomy, selective neck dissection and primary vocal prosthesis insertion. In both cases, the infection spread to thoracic region and in one of the patients NF was associated with Lemierre's syndrome ( thrombosis of the internal jugular vein). In both patients, vocal prosthesis was inserted during the infection and did not influence the healing process.

Michael Douglas's videos about the importance of early diagnosis of oral cancer and his recent lecture about his battle with cancer

Michael Douglas who is an oral cancer survivor has released a video that underscores the importance of early diagnosis of oral cancer. It can be watched on YouTube.  Oral cancer is a disease in which malignant (cancer) cells form in the lips, oral cavity, or oropharynx. The number of new cases of oral cancer and the number of deaths from oral cancer have been decreasing slowly. Tobacco and alcohol use can affect the risk of developing oral cancer. Other risk factors are being infected with a certain type of human papillomavirus (HPV), exposure to sunlight (lip cancer only) and being a male.

There is no standard or routine screening test for oral cancer. Screening for oral cancer may be done during a routine check-up by a dentist or doctor. The exam will include looking for lesions, including areas of an abnormal white patch of cells (leukoplakia) and an abnormal red patch of cells (erythroplakia). These lesions on the mucous membranes may become cancerous.
