Surgery along with chemotherapy and radiation therapy is one of the traditional treatment method for mesothelioma.
- Pleurodesis
- Pleuroperitoneal shunt
- Pneumonectomy
- Pleurectomy

Traditional mesothelioma Treatments
Traditional mesothelioma treatments typically involve a combination of surgery, radiation therapy, and chemotherapy, depending on the stage of the disease and the patient’s overall health. Mesothelioma is a rare and aggressive form of cancer primarily associated with asbestos exposure, and treatment approaches are aimed at managing the disease, alleviating symptoms, and potentially extending the patient’s life.

Surgery:
- Surgical options for mesothelioma treatment include:
- Extrapleural pneumonectomy (EPP): This procedure involves the removal of the affected lung, the lining around it (pleura), parts of the diaphragm, and sometimes the pericardium (the sac around the heart).
- Pleurectomy/decortication (P/D): In this procedure, the surgeon removes the pleura and any visible tumors, but the lung is preserved. This is a less aggressive option compared to EPP.
- Cytoreductive surgery (CRS): CRS is often combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal mesothelioma.
- Surgical options for mesothelioma treatment include:
-
Radiation Therapy:
- Radiation therapy may be used before or after surgery to target and shrink tumors or to alleviate symptoms. It’s also used as a palliative treatment to relieve pain and other discomfort.
- Two main types of radiation therapy are used:
- External beam radiation: This involves directing high-energy X-rays from outside the body onto the tumor.
- Intraoperative radiation therapy (IORT): Radiation is delivered directly to the tumor during surgery.
- Chemotherapy:
Chemotherapy is a systemic treatment used to kill cancer cells throughout the body.
-
- The most common chemotherapy drugs for mesothelioma include pemetrexed (Alimta) and cisplatin, which are often used in combination.
- Chemotherapy can be administered intravenously or directly into the chest or abdominal cavity (intraperitoneal chemotherapy) in some cases.
These traditional treatments are often used in combination to maximize their effectiveness. The specific treatment plan for mesothelioma patients depends on factors such as the type and stage of the disease, the patient’s overall health, and individual preferences. Additionally, other treatments, such as immunotherapy and targeted therapy, may be considered, especially in clinical trials or if the disease does not respond well to traditional treatments.
It’s essential for mesothelioma patients to work closely with a medical team experienced in treating the disease to determine the most appropriate treatment plan for their unique situation. The treatment aims may include curing the disease, extending life, managing symptoms, and improving the patient’s quality of life.
There are two kinds of malignant mesothelioma surgery having different aims: an aggressive surgery is aimed at long-term control of the symptoms and palliative procedures are carried out in order to relieve them.
Aggressive Surgery. Extrapleural pneumonectomy, involving the removal of pleura, the lung, the diaphragm and the pericardium, is the most wide-spread type of aggressive surgery. This aggressive and difficult procedure is aimed at removing the tumor cells in maximum possible volumes. This procedure is not carried out by all hospitals because of its very specialized nature and high risk concerning death within the period of 30 days after the surgery is done. In order to find out whether the patient is able to tolerate this surgery, he or she is evaluated carefully, nevertheless, extrapleural pneumonectomy is mostly appropriate for younger patients because of their health and earlier stages of cancer.
Palliative Surgery. The symptoms of advanced malignant mesothelioma can be relieved and controlled via this surgical method. Patients often suffer the reduction of the lung function, caused by various reasons; the most common is collection of the fluid (pleural effusion) and the tumor compressing the lung with its mass. These processes can lead to breathlessness and chest pains.
Surgery is generally not the cure, but it is a good means to prolong the patient’s life considerably. A careful evaluation of the patient’s entire health is required while deciding whether to apply surgery to malignant mesothelioma. The aim of this testing is to ensure that the cancer didn’t produce metastases and advanced to other organs, as well as to find out the general health of the lung and heart functions of the patient.
Three procedures are used in the surgical management of MPM:
- thoracoscopy with pleurodesis
- pleurectomy/decortication (P/D)
- extrapleural pneumonectomy (EPP)
Thoracoscopy
This is used mostly for obtaining a sample of tissue for diagnosis, but it is also useful in palliative treatment of recurrent or symptomatic pleural effusions for pleurodesis. There is no considerable difference in the effect of usage such sclerosing agents as bleomycin, tetracycline, and talc. The cheapest agent is talc and, moreover, it can be fed through a chest tube as slurry or through thoracoscope.
Pleurectomy/decortication (P/D)
During this procedure the visceral, parietal, and pericardial pleura are removed from the apex of the lung to the diaphragm. At early stages of the disease only complete resection is appropriate, though the majority of these patients suffer local recurrence. The retained lung limits the doses of postoperative radiation compared to EPP. Pleurectomy/ decertification may treat the disease at its very early stage T1a. It goes along with high local recurrence rate and survival not more than 5 years.
There is no clear data concerning the fact whether adjuvant radiotherapy or chemotherapy, neoadjuvant therapy, radiation, intrapleural chemotherapy or brachytherapy and others can improve survival. The most common usage of pleurectomy/decertification is for palliation symptoms and treating in case planned extrapleural pneumonectomy is not appropriate. An effective in extending survival and safe treatment was found during recent research of dyperthermic perfusion utilizing intrapleural cisplatin at a dose up to 225 mg/m2 and i.v. thiosulfate.
Extrapleural pneumonectomy (EPP)
It is the most aggressive treatment. During this procedure the en bloc resection of the visceral and parietal pleura, lung, pericardium, and ipsilateral diaphragm is carried out. The surgeon and institution performing the operation critically select patients for EPP.
Extrapleural pneumonectomy for stage I and II induces long term survival in about 20% of patients. Careful selection of patients utilizes premorbid exercise capacity, absence of bronchitis or astma (Butchart 1999). It is a surgery riddled with mortality, particularly if done in the right hemithorax and out of skilled centers. Extrapleural pneumonectomy is often done as part of multimodality therapy, including chemotherapy – intrapleural hyperthermic and cisplatin based, radiation to the operated hemithorax, and systemic adjuvant chemotherapy.
Thoracentesis is commonly performed to treat effusion in pleural mesothelioma. This surgery involves inserting a needle into the chest to drain the excess fluid, relieving breathlessness and chest pain. Talc may be introduced into the pleura to limit recurrence of the effusion. Pleurectomy is the surgical removal of the pleura. This procedure is performed to reduce pain caused by the tumor mass, or to prevent the recurrence of pleural effusion. For peritoneal mesothelioma, surgery generally is aimed at relieving symptoms, such as recurrent ascites or bowel obstruction. As with pleural mesothelioma, complete surgical removal of the entire tumor is unlikely.
Radiotherapeutics along with chemotherapeutics and surgical service is one of the conventional processing technique for mesothelioma.
In radiation treatment, medical officer use high-energy x-rays, which can kill carcinoma cellule and reduce tumors. Emission of x-rays may come from a facility exposed the body (outsideness radiation treatment) or from putting matters, which emit radiation (radioactive isotopes) through slender plastic tubing in the area where the carcinoma cellules were found (inside radiation treatment).
The information from the Joint Center for Radiation treatment in Boston offers radiation dose not less than 40 Gy in order to attain reprieve. In the post-EPP setting, higher dosages of radiation therapy can be delivered smoothly and are associated with a very low risk of local backset, with distant secondary neoplasm being the most usual form of backset. In the research by Boutin et al,25 dosage to small zones was found to be highly forceful at reducing cancerous seeding along biopsy nerve tracts.
Some medical officers use radio therapeutics as the basic therapy for Mesothelioma in patients who might not be cured by the surgical service. Sometimes medical officers use beaming in conjunction with surgical service, or as a method to alleviate symptoms such as pain, labored breathing, depletion and trouble with swallowing.
Types of radiotherapy
- external radiotherapy
- internal radiotherapy
- prophylactic radiotherapy
- palliative radiotherapy
Medical officers can give radiotherapeutics either from internally the body (called inside radiotherapeutics) or from outside the body (called outsideness radiotherapeutics), using x-rays or cobalt beaming. The outsideness radiotherapeutics is free from pain, dispensary maneuver. This mesothelioma medicine is often divided into few sessions, which are called fractions, generally one session a day for five days with relax at the weekend. Fractions can help to decrease the affection to normal cellules (External Beam Radiotherapy, CancerBacUp).
Outsideness radiotherapeutics
In outsideness radiotherapeutics, the specialist uses one of two facilities. A linear accelerator reproduces high-energy radiation by electricity to figure a flood of fast-moving ultimate particles. Another type of facility includes an active material, usually cobalt-60, as its radiation source (What is Radiation Therapy, Oncolink).
Inside radiotherapeutics
Inside radio therapeutics comprises either placing solid, radioactive substance within the tumor or administering a radiogenic fluid by mouth or parenteral infusion. Inside radiotherapeutics is a stationary maneuver that permits the delivery of higher dosage of radiation than in outsideness radiotherapeutics.
Preventive radiotherapeutics succeeding any intrusive maneuver (whether biopsy or drainage). There is a hazard of dissemination along the track and this may result in a sickly mass, nevertheless the risk of clinically important sickness is uncertain. Radiotherapeutics to the drain site with 21 Gy in three diurnal fractions in a stochastic research of 40 patients decreased the hazard of dissemination from 40% to zero. It is remarkable that, in an earlier non-stochastic research, Boutin et al33 had supervised backsets when the radiotherapeutics was postponed for 2 months. The suggestion is that radiotherapeutics should be given during 4 weeks. Riding on local position, it may help to book the radiotherapeutics before the maneuver is carried out.
Palliative radiotherapeutics
Palliative radiotherapeutics for hurt or thoracic wall masses in two retrospective series hurt enhanced in 23 of 37 patients (62%). Some specialist found that first courses of palliative radiotherapeutics conduced to enhanced signs in no less than 43 of 87 patients (49%). This is perhaps a disparagement as the vulnerability was uncertain in 15 of the patients. These series also involved patients with cellular spilt and SVCO (Superior Vena Caval Obstruction). Substantial vulnerability of thoracic wall masses was found in five out of nine patients.35 In these series a multiplicity of radiotherapy conditions was used. Practically all clinical oncologists in UK would use a short-time course of therapy of commonly no more than 2 weeks’ time span with the current condition being estimated by the size of the treatment zone and performance status.
Labored breathing is occasionally enhanced by radiotherapeutics. The relief of pain may be disappointingly short existed and there is no indication for a dosage vulnerability relationship to radio therapeutics under these occasions.
Collateral Effects of Radiotherapeutics in mesothelioma therapy
Before you are exposed radiotherapeutics, your medical officer will tell you about collateral effects that you may suffer after the maneuver. Being notified helps you to manage complications. Be sure to notice any impediments that you collide as the treatment makes headway. The doctor will know what is a serious complication, and what have a provisional effect.
The most general collateral effect from radiotherapeutics is tiredness or fatigue. This is a weakening circumstance when you cannot do even easy everyday tasks. Patients often experience fatigue towards the end of the course of radiotherapeutics, and may not recuperate fully until some months after the therapy ends.
We suppose that you are pliable to yourself while exposing radiotherapy. Take a forty winks, get family help if it is possible. Whereas you want to be individual, do consider letting relatives or friends help over. You should also meditate your day so that your housework is spread out and you can have a rest.
Some people can get skin eruptions or skin affectivity near the radiotherapy zone. We recommend wearing loose-fitting clothes, and narrating your medical officer about the complications so that he or she may consider any prescription salve or embrocation. These reactions of the skin commonly reduce after the radiotherapeutics ends. The skin in the treated zone seems embrowned and then becomes darker. But it will go away in a few weeks.
Patients with pleural mesothelioma may have a tussis or have impediment deglutition after radiotherapeutics. A dietitian will help you to choose proper food and instruct you about managing with the difficulties.
There are 2 types of chemotherapy in mesothelioma treatment:
- single-agent chemotherapy
- combination chemotherapy
The sense of chemotherapy is killing cancerous cells by using special drugs. It can be applied for different purposes: neo-adjuvant therapy is used for preoperative tumor size decrease, adjuvant chemotherapy helps to kill the rest of cancer cells that were not destroyed during the surgery, another usage is increasing the effectiveness of radiation therapy or immunotherapy and destruction of the cancerous cells that have split from the initial tumor. In case the surgery cannot be applied to the patient, chemotherapy is possible stand-alone treatment for him or her.
The doctor has to discuss a specified treatment and possible side effects with his patient before applying chemotherapy procedures.
Here is the list of possible questions the patient may ask the doctor about the treatment:
– What is the amount of treatments I’ll be given?
– Which drugs or combination will be used?
– What is the way of the drugs administration? (e.g. intravenous, pills or other)?
– Where will the treatment be carried out? Hospital, doctor’s office, and so on?
– What is the length of each treatment?
These questions can be asked concerning side effects:
– What are the side effects of the drug I’m going to receive?
– Can any of the listed side affects occur?
– How can I ease these side effects?
– Should I report of some certain effects immediately?
– How is it possible to reach a health professional if I’ll have to call later?
Healthy cells usually recover after applying chemotherapy that’s why side effects generally vanish after chemotherapy procedures are completed. Overall health of the patient and the type of chemotherapy he or she was given are some of the factors on which the length of the period required to recover from side effects depends. Your doctor is able to inform you about the treatment.
Doctors are not completely trust the possibility of chemotherapy to control mesothelioma symptoms. ‘Active symptom control with or without chemotherapy for mesothelioma’ or MS-01 is the British name for clinical trial that aids them in taking the right decision. This trial is based on comparison of non-chemotherapy treatment with two chemotherapy combinations. The goal of this trial is to define the better way to control mesothelioma symptoms.
The trial of raltitrexed (Tomudex) and cisplatin complex usage was announced in 2004. This combination is supposed to work better than stand-alone cisplatin treatment. Finally, these two kinds of trial didn’t differ from each other much.
Chemotherapy may apply drugs as single agets whether the most common situation is combined usage of two or more drugs, called “combination therapy”. This therapy is applied during the usage of Alimta, an experimental medicine which is developed over the expanded access program carried out for mesothelioma patients. This drug is prescribed in combination with cisplatin or gemcitabine, which are standard medicines for chemotherapy.
Adjuvant and Neoadjuvant mesothelioma’s therapy
This treatment is applied to increase the patient’s chances to cure and is applied after primary treatment procedures.
PDT (Photodynamic therapy), chemotherapy and radiation therapy are parts of adjuvant therapies. Photodynamic therapy is aimed at destroying any tumor pieces left after surgery. Photodynamic therapy is not completely accepted as a safe one due to some possible complications, despite the fact that phases I and II trials are supposed to be generally safe. It has no proven ability to keep a local control for a long time.
Usually radiation therapy or chemotherapy is applied before the surgery in order to raise the chances for success of the primary treatment.
Adjuvant Hormonal Therapy:
Adjuvant Hormonal Therapy: This evaluates the combination of Nolvadex® and anti-aromatase agents or the latter alone in order to find out the best regimens of hormonal treatment applied to women having an adjuvant setting of ER-positive breast cancer.
Neoadjuvant Hormonal Therapy: Neoadjuvant therapy is held before the surgery to make the tumor smaller and make the following complicated surgical actions easier. The evaluation of anti-aromatase agents happens in the neoadjuvant setting.
New Adjuvant Chemo-radiation Therapy: The adjuvant therapy is the scheduling of extra treatment procedures after the surgery is carried out to minimize the risk of cancer recurrence. The usage of adjuvant therapy while treating all stages of gastric cancer but for IA stage during clinical trials has shown an increase of survival. The work of finding out the most suitable adjuvant therapy is carried out nowadays at clinical trials.
The name of the postoperative chemotherapy is adjuvant therapy. This treatment is applied in the following cases:
– The lymph accumulated in the nodes under the patient’s arm has some breast cancer cells in it.
– The patient used to have a vast breast cancer.
– The breast cancer of the patient was too much advanced.
– The cancer cells of the patient don’t give positive response to hormone receptors and are not supposed to react to the hormone therapy accordingly.
Adjuvant therapy is applied in case there is a suspicion that some cancerous cells could have split from the breast tumor and extended over the body earlier than the tumor was removed. In this situation cancerous cells can be found in any area of the patient’s body. Adjuvant therapy destroys these cells minimizing the risk of cancer recurrence.
More than one drug is generally used during the chemotherapy. The Cochrane collaboration has prepared the report in 2004 where it sad that such applying of chemotherapy makes the survival higher and the risk of the cancer recurrence lower. Multi-drug chemotherapy is the most helpful for women younger than 50 but the positive effect can be seen at the patients up to 69. The contemporary knowledge doesn’t allow to state how useful such treatment is for women older than 70.
Chemotherapy helps to those who still have periods in a different way. The ovaries produce oestrogen, a hormone stimulating growth of the breast cancer, that’s why the chemotherapy that prevents ovaries from producing this hormone can help. This is supposed by some specialists the main reason for great success of this adjuvant treatment for women in pre-menopausal period. The negative side is that the lack of oestrogen may be the reason of early menopause that will make the woman infertile.
Still, this is not common situation. The ovaries of some women restore their functioning after they have suffered chemotherapy. This fact is quite dependant on the age of the patient, as well as on the kind of drugs applied during the chemotherapy. In case the periods do not come within a year then it unfortunately means that ovaries are unlikely to restore their functioning.
Mesothelioma combination therapy
As is known, there are three medical treatment of mesothelioma: single-modality, bimodal and combination (or trimodal).
Single-modality treatment is used for pleural mesothelioma in case of radio therapeutics, chemotherapeutics or surgical service is incapable to prolong life by more than some months at most. More recently, combined modality methods to enhance effectiveness have been reported. In this situation, EPP is dedicated not as a curative, but as a cytoreductive procedure. Bimodal and trimodal treatment methods of operation have been tried: surgery with radiation, surgery with chemotherapy, chemotherapy with radiation, and all three methods combined. Combinations of chemotherapeutics with radiation have occur with very limited advance.6 9 81 82 Currently, a disordered intergroup study is testing the implication of radio therapeutics with and without the following administration of doxorubicin.
Some research workers have integrated EPP with consecutive post surgical chemotherapeutics
Some research workers have integrated EPP with consecutive post surgical chemotherapeutics and up to 5,500 cGy of accessorial radio therapeutics to the post surgical hemithorax. The preliminary accessorial chemotherapy nutritional care of four to six cycles of cyclophosphamide, doxorubicin, and cisplatin, was considered to be impactful, but because of considerable interference of myocardium, it has been changed to a nutritional care of carboplatin and paclitaxel. Patients in I research with epithelial mesothelioma and without mediastinal lymph node involvement at resection had a difference 5-year survival rate of 39%.
Patients, who have tumors with mixed histologic findings or sarcomatous tumors, have 2- and 5-year rates of survival 20% and 0%, accordingly. Full-thickness entanglement of the hemidiaphragm at the time of operating resection was also consociated with a deficient prognosis. The most usual distribution of tumor backset was the ipsilateral hemithorax (35%), ensued the peritoneal cavern (26%) and the contralateral hemithorax (17%). Nearly 4% of patients who got trimodality therapy expanded backset at distant sites.
Chemotherapeutics, radio therapeutics or surgical service have been used in single- and bi-modality treatment for mesothelioma, but the benefit on lifetime and local control has not been sufficient. Surgical measure, as decortication of lungs or EPP, usually allow reprieve. Practically all single agents are comparatively inefficient. Combining doxorubicin, cyclophosphamide and cisplatin may guarantee response rates of 20% to 30%.
The deficiency of any medicative single modality treatment for mesothelioma has led our group and others to estimate an offensive trimodal approach to this malignancy. Our common therapy nutritional care consists of a cytoreductive surgical service accompanied by radio therapeutics or chemotherapeutics. Such method set the beneficial effects to the maximum and the adverse effects to the minimum of accessorial therapy.
Cytoreduction
The two operating maneuvers that are actually used in cytoreduction are EPP and decortication/ pleurectomy. These two maneuvers have not been immediately compared in assumed stochastic trials. Each operating maneuver has advantages and disadvantages. The advantages of decortication/ pleurectomy are its low death-rate (25%) 24 and case rate (2%). So, this surgical service can be realized in patients with a less convenient cardiorespiratory status than that demanded for EPP.
Nevertheless, decortication/pleurectomy may not be accomplished if the pleural cavity is tellingly wrecked by tumor growth, and the dosage of post-surgical radio therapeutics permitted to the chest cavern is limited due to the attendance of the lung parenchyma and the risk of extension of postradiation pneumonitis. Besides, the local control of malum attained by pleurectomy may not be impactful, whereas the increase of external direct radiation with or without perioperative brachytherapy may set the local recurrence to the minimum. The cytoreduction accomplished by the technique is not as impactful as the decrease attained with EPP. Sufficient reduction of tumor in the disruption or near the incisure is also embarrassing and dangerous.
Some surgeons prioritize decortication/pleurectomy as the primordial technique for cytoreduction in DMPM. Rusch et al26 and others appended intrapleural chemotherapeutics with taking mitomycin and cisplatin after the operation. Our group in the institute tried to follow with EPP in all competent patients and essentially accomplish a pleurectomy in those patients who are unable to survive the after-effect of EPP.
EPP has some advantages in the setting of trimodality treatment
EPP has some advantages in the setting of trimodality treatment. First, destruction of the pleural cavity by tumor does not prevent EPP as the perfect pleural envelope is put away in bulk. Besides, radiation pneumonitis ensuing surgical service is not a concern because the lung has been exsected and an increased total exposure dose might be righteous. Most significantly, EPP has been consociated with longer than average median survival rates (in some series for 21 months ). Nevertheless, this expressed favour could reflect earlier stages of disease rather than an effort of the influence. At the present time, the death-rate (5%) and case rate (22%; extensive complicating disease: 12.5%) are much lower in particularized centers than those informed in the older series.13,15 However, the rates of complication following EPP are increased than those following decortication of lungs. Another shortcoming of EPP is that the patient must have sufficient physiologic reserve and suitable cardiac function to suffer an EPP.
