Mesothelioma is a form of [[Oncology|cancer]] that appears in the epithelial layer called mesoderm that lines the pleurae, peritoneum, and pericardium.  Mesothelioma affects mostly older individuals who have been occupationally exposed to asbestos. Mesothelioma has been described as an insidious neoplasm because of its long latency period—up to 40 years in some series—after exposure to asbestos. It arises in the mesothelial surfaces of tissues in the pleura but can also occur in the peritoneum and the tunica vaginalis. Peak incidence occurs in the 5th and 6th decades of life.<ref>Mott FE.

== Epidemiology ==
== Epidemiology ==
Approximately 3000 incident cases of mesothelioma are registered each year in the United States. The incidence rate varies between less than 1 case per 100,000 persons in states with no asbestos industry to 2 to 3 cases per 100,000 persons in states with an asbestos industry. The mean age of death from mesothelioma in the United States was 72.8 years, with a male‐to‐female (M: F) mortality ratio of 4.2:1, as men were traditionally more likely to be employed in trades involving asbestos exposure.<ref name=":0" />  
Mesothelioma is uncommon and accounts for 5-28% of all malignancies that involve the pleura.

* Not all types of asbestos are strongly implicated, with crocidolite being the main causative fibre type. Given the sources of asbestos exposure being predominantly mining, construction, lagging and machinery mechanics, 60-80% of cases are encountered in males, in general, 20 to 35 years after exposure. Some areas of the world have very regional hotspots, such as Belfast in Northern Ireland, due to the historic shipbuilding industry.

== Pathophysiology ==
[[File:Mesotheliomia pm.png|right|frameless|350x350px]]
Mesothelial cells are much more susceptible than other cell types to asbestos cytotoxicity. When asbestos and other fibers reach the pleura and peritoneum through lymphatics, they remain in place for months or years, triggering a [[Inflammation Acute and Chronic|chronic inflammatory]] process that helps in the production of mutagenic oxygen radicals induced by asbestos are responsible for asbestos pathogenesis and carcinogenesis.<ref name=":0" />


Between 1994 and 2008, age‐adjusted mesothelioma mortality rates increased by 5.37% per year worldwide<ref name=":0" />.  In a meta-analysis, a significantly increased risk of pleural mesothelioma was reported for both household exposure and neighborhood exposure. Different strengths of association were observed according to fiber type, with the strongest associations noted when amphibole was present and the weakest when chrysotile was present. Therefore, the types of fibers to which residents are exposed to influence mesothelioma rates. Crocidolite and amosite fibers are considered the main cause of mesothelioma among occupationally exposed individuals (mining, road construction, off‐road driving, etc).<ref name=":0" /> 
The three types of mesothelioma are epithelioid, sarcomatoid, and mixed (epithelioid type is associated with better outcomes).  


== Pathogenesis ==
* The tumor is often multifocal, forming multiple nodules starting with the parietal pleura.

* Spread occurs locally in the visceral pleura before extending to the chest wall, diaphragm, or mediastinum.  
* Regional lymph node spread begins with the bronchopulmonary or hilar lymph nodes before moving to the carinal, internal mammary or peridiaphragmatic nodes.


Asbestos fibres are inhaled and migrate to the pleura. Within the pleural space, fibres cause irritation and a repeated cycle of tissue damage and repair is established. The presence of oxygen free radicals, released by asbestos fibres when phagocytosed by macrophages, causes intra-cellular DNA damage and abnormal repair. Asbestos fibres also penetrate mesothelial cells, where they interfere with mitosis, generate mutations in DNA and alter chromosome structure. Asbestos-exposed mesothelial cells release inflammatory cytokines, including tumour growth factor-β, platelet-derived growth factor and vascular endothelial growth factor (VEGF). This creates a favourable microenvironment for tumour growth. Finally, asbestos induces the phosphorylation of various protein kinases (mitogen-activated protein and extracellular signal-regulated kinases 1 and 2), leading to increased expression of proto-oncogenes and further promotion of abnormal cellular proliferation.<ref name=":1">Bibby AC, Tsim S, Kanellakis N, Ball H, Talbot DC, Blyth KG, Maskell NA, Psallidas I.

The Mesothelioma prognosis remains disappointing, although there have been some modest improvements in prognosis from newer chemotherapies and multimodality treatments.
Treatment continues to be challenging and the long-term survival is poor. Single modality treatment ([[Surgery and General Anaesthetic|surgery]], radiotherapy, [[Chemotherapy Side Effects and Syndromes|chemotherapy]], [[immunotherapy]] and even photodynamic therapy) have not been shown to improve survival. More recently multi-modality treatment has had some impact on favourable subgroups (early disease, and epithelioid histology). Treatment includes:

* extrapleural pneumonectomy
The role of surgery in pleural mesothelioma is controversial as it is difficult to predict who will benefit from aggressive management, even when local therapies are added to existing or novel systemic treatments. Treatment outcomes are improving, however, for peritoneal mesothelioma. Multidisciplinary international collaboration will be necessary to improve prevention, early detection, and treatment.<ref name=":0" />
* adjuvant chemotherapy
* radiotherapy


There is various medical management for mesothelioma. Chemotherapy is the only treatment modality that has been shown to improve survival in MPM. targeted therapy has recently shown a positive impact.<ref name=":1" /> Radiotherapy is used in two main settings in MPM: as a palliative measure to treat symptoms or an adjuvant to surgery and chemotherapy in the context of trimodality treatment. The benefit of surgery in MPM is much debated, and there is a need for robust randomised trial data to elucidate its efficacy and clarify its role in management. Some surgical procedures are extrapleural pneumonectomy (EPP),extended pleurectomy with decortication, and partial pleurectomy ''via'' VATS.<ref name=":1" />
The prognosis is poor for all tumour types with a median overall survival without treatment of 4-12 months.

Introduction[edit | edit source]

Mesotheliomia.jpeg

Mesothelioma, also known as malignant mesothelioma, is an aggressive malignant tumour of the mesothelium, with most tumours arise from the pleura[1]. The subtypes of asbestos strongly associated with malignant mesothelioma are the amosite and crocidolite asbestos[2].

Mesothelioma

  • Affects mostly older individuals who have been occupationally exposed to asbestos.

Nonspecific symptoms such as unintentional weight loss, appetite loss, cough, fatigue, and chest wall mass may also occur.[2]

Physiotherapy management[edit | edit source]

The Active Cycle of Breathing Technique..png

Patients are encouraged to enter a rehab program to recover functionality after treatment. A good diet should be encouraged as most patients are frail and emaciated. Home oxygen and breathing education (see Image 6 ACBT) are often required[2].

Physiotherapy is an integral part of the multidisciplinary approach treatment for patients with cancer.[8]
All patients who suffer from mesothelioma are required to undergo physical therapy, even if they have already undergone surgery, chemo, and/or radiation. The reasons for this include:

  • All three types of treatment are exceptionally difficult on the body. With their many negative side effects, the body needs physical therapy to regain the strength it once had.
  • Without physical therapy, these treatment options are less successful. The body needs all the strength it can get to successfully respond to all treatment options.
  • Therapy with a physical therapist is usually scheduled by the medical professional.

Mesothelioma treatments are designed to help patients feel more comfortable and hopefully extend their quality of life. While there is no cure for mesothelioma at this time, these three treatment options are the best bet. Of course, the doctor might have other suggestions as far as using a combination of these treatments and other medications to help client live as comfortably as possible. Each case of mesothelioma is unique, meaning each treatment method will differ from others.

Goals include: Respiratory care; pain management; improve the patient level of fatigue; improve bodily muscular and cardiovascular endurance.
