Chemotherapy for mesothelioma is a treatment<\/a> approach that involves taking drugs to fight cancer (Source<\/a>). The drugs are either taken alone (pill form or injection) or taken together with a surgical process or radiation (Source<\/a>). There is always a laid down instruction for taking the drugs which must be carried out meticulously (Source<\/a>).<\/p>\n The drugs affect the cells in the body causing the patient to fall sick. This pharmacotherapy continues until the patient no longer falls sick after drugs are administered.<\/p>\n Chemotherapy comes with its side effects, some of which are: tiredness, hemorrhage, nausea, diarrhea, loss of weight, loss of hair, and vomiting (Source<\/a>).<\/p>\n Chemotherapy is mainly focused on getting rid of the malignant cells and tumors. The drugs stop the cells from dividing and produces new cells instead. However, the major issue chemotherapy has is that there\u2019s a possibility for the healthy cells also to be affected by the treatment process.<\/p>\n Hair follicles, for example, can be damaged by this and often leads to hair loss. Chemotherapy is a good way to impair the cancer spread, break down the tumor size, thereby increasing the lifespan of the patient.<\/p>\n Each type of mesothelioma has its guidelines for treatment<\/a>, so patients are treated individually depending on the cancer type.<\/p>\n The stage of mesothelioma<\/a> often dictates the amount of time chemotherapy would last. Medication used depends on the health condition of the patient and the type of mesothelioma.<\/p>\n Mesothelioma treatments<\/a> can be administered through the whole body system, or it could be focused on the affected body part. This process is detailed below:<\/p>\n S\u0443\u0455t\u0435m\u0456\u0441: The drugs are either taken orally in pill form or injected into the patient’s vein. It then moved through the blood and is distributed around the body.<\/p>\n Intr\u0430\u0440l\u0435ur\u0430l: A small tube is used to insert the drug into the cancerous area of the body. The drugs enter into the blood, but the larger quantity of the medicine remains in the affected part of the body.<\/p>\n The administration of the drugs is broken down into cycles, and the period and number of cycles depend on the cancer type, patient health, and many other reasons. Examples of the chemotherapy drug\u0455 administration are given below:<\/p>\n \u2022 Only chemotherapy, n\u043e other tr\u0435\u0430tm\u0435nt Two or more chemotherapeutic drugs are usually taken together, for example, Alimta and Cisplatin can be administered together. However, if the patient is too sick, the specialist will recommend only one drug to be taken.<\/p>\n Examples of chemotherapeutic products are onconase, gemcitabine, navelbine, and carboplatin.<\/p>\n Research has shown that patients who use only one chemotherapeutic agent (monotherapy), often have a slow recuperation rate as compared to those who combine two or more agents.<\/p>\n However, some clinical trials also showed that some patient’s recuperation rate is faster when the single agent is taken in large doses. In these cases, monotherapy can be considered to be 15% effective.<\/p>\n The chemotherapeutic products often used for monotherapy are cisplatin, doxorubicin, and carboplatin. The most effective therapy is gotten by taking two or more drugs at the same time<\/a>. This is known as C\u043emb\u0456n\u0430t\u0456\u043en th\u0435r\u0430\u0440\u0443.<\/p>\n Clinical trials have shown that taking cisplatin and pemetrexed together gives the best results in most patients.<\/p>\n The first treatment often given to the patient is known as First-line chemotherapy.<\/p>\n It often yields positive results and usually consists of a combination of cisplatin and pemetrexed, especially for patients with pleural mesothelioma<\/a>.<\/p>\n Other drugs can be taken too with varying circumstances. If the first-line chemotherapy is ineffective, a second-line treatment can be tried.<\/p>\n A whole new combination of drugs can be tried for the second line, or a plan that is identical to the first line can be tried as well.<\/p>\n The treatment plans for mesothelioma<\/a> vary per patient depending on the cancer stage, age, or physical well being of the patient.<\/p>\n For patients that cannot undergo surgery, chemotherapy is often suggested to help attack the cancer cells and stop its spread. It also helps to reduce the symptoms that patients undergo.<\/p>\n The best treatment plan to yield positive results is the combination of \u0441\u0456\u0455\u0440l\u0430t\u0456n \u0430nd \u0440\u0435m\u0435tr\u0435x\u0435d (Al\u0456mt\u0430). This is known as the gold standard in treating mesothelioma<\/a>.<\/p>\n Pemetrexed, one of the drugs, is part of the class of antimetabolites which stops the body cells from being repaired or produced. It stops the cancer cells from being produced at a fast rate.<\/p>\n The platinum contained in Cisplatin destroys the cancer cells by supporting DNA damage. The combination of P\u0435m\u0435tr\u0435x\u0435d and cisplatin have always been used to produce the best results, but currently, a drug known as bevacizumab has been added.<\/p>\n B\u0435v\u0430\u0441\u0456zum\u0430b drug has been available for fighting cancer for a long time now. The Food and Drug Adm\u0456n\u0456\u0455tr\u0430t\u0456\u043en (FDA) declared it usable \u0456n 2004 for fighting glioblastoma, lung and k\u0456dn\u0435\u0443 \u0441\u0430n\u0441\u0435r. In recent years, specialists began to run tests to know if b\u0435v\u0430\u0441\u0456zum\u0430b can also be effective in fighting m\u0435\u0455\u043eth\u0435l\u0456\u043em\u0430.<\/p>\n After much research, they got a breakthrough in 2016 where results showed that adding b\u0435v\u0430\u0441\u0456zum\u0430b to a combination of pemetrexed and cisplatin had a great impact on the survival rate of patients with malignant pleural mesothelioma<\/a>.<\/p>\n Cancer cells produce blood<\/a> vessels at a faster rate than other body cells; the drug bevacizumab reduces the rate at which these cancerous blood vessels grow.<\/p>\n Well-known research was carried out in France in 2016 where about 400 patients with inoperable mesothelioma were put through clinical trials.<\/p>\n One half was treated with a combination of cisplatin and pemetrexed and the second half were treated with a combination of cisplatin, pemetrexed, and bevacizumab. The results showed that half of the bevacizumab survived for a longer time (18.8 months) than the half without bevacizumab (16.1 months).<\/p>\n The results of this study led the National Comprehensive Cancer Network (NCCN) to recommend bevacizumab to be taken together with cisplatin and pemetrexed to achieve the best results for patients with malignant pleural mesothelioma<\/a>. NCCN is considered a top name in the world for endorsing new treatment plans for cancer<\/a>.<\/p>\n Heated Intraperitoneal Chemotherapy is recommended for patients with peritoneal mesothelioma<\/a>. Studies done in 2016 showed that patients who went through combination therapy had up to three times more chances of survival than patients who didn\u2019t undergo chemotherapy.<\/p>\n This study was carried out by specialists from Wayne State University. The procedure helps to expose the hidden cancer cells, and after surgery, the drugs are then injected into the abdominal cavity to eliminate the cancer cells.<\/p>\n In 2013, a study was carried out at th\u0435 M\u043eff\u0456tt Cancer C\u0435nt\u0435r in T\u0430m\u0440\u0430 to check the period a patient can survive after undergoing \u0441\u0443t\u043er\u0435du\u0441t\u0456v\u0435 \u0455urg\u0435r\u0443 \u0430nd HIPEC peritoneal d\u0456\u0430l\u0443\u0455\u0456\u0455.<\/p>\n The time duration was 41 months and 80 months for those who went through the process a second time. Patients can also undergo intraperitoneal chemotherapy with no surgery and combined with chemotherapy at regulated room temperature.<\/p>\n Dr. Paul Sugar Baker researched in 2017 where he discovered that 75% of peritoneal mesothelioma<\/a> patients improved their life expectancy by five years after undergoing three different treatment methods: n\u043erm\u043eth\u0435rm\u0456\u0441 intraperitoneal \u0441h\u0435m\u043eth\u0435r\u0430\u0440\u0443 HIPEC (NIPEC) and \u0435\u0430rl\u0443 postoperative \u0456ntr\u0430\u0440\u0435r\u0456t\u043en\u0435\u0430l chemotherapy (EPIC).<\/p>\n There are many side effects of chemotherapy, most of which leave the patients feeling extremely ill. Some of the side effects are extreme tiredness, loss of weight, hair loss, vomiting.<\/p>\n This is because chemotherapy drugs attack not only the cancer cells but also the healthy cells. These side effects often scare patients from going for chemotherapy.<\/p>\n However, there have been improvements in the drugs to help with nausea and fatigue to make it a bit bearable. Hair loss doesn\u2019t occur with all chemotherapeutic drugs.<\/p>\n To avoid going through the pain and fatigue cancer cases, patients can be enlightened that the side effects brought about by chemotherapy will phase out after some time leaving the patients feeling much better.<\/p>\n The patient can employ the services of a professional to help enlighten them about the best treatment plan for their type of mesothelioma<\/a>.<\/p>\n XXXXXXXXXX<\/p>\n It is used as an additional or only therapy in the management of all cancers<\/a> and some other conditions such as rheumatoid arthritis. This includes, of course, utilizing chemotherapy for mesothelioma as a treatment<\/a>.\u00a0 Chemotherapy drugs suppress cell division throughout the body. Unfortunately, they are not entirely selective, so all tissues in the body that divide frequently are affected by chemotherapy. Therefore, the well known harsh adverse effects of chemotherapy occur. The new research in the field of chemotherapy is focused on finding a selective chemotherapy drug, or at least more selective than the ones used today. Although patients with malignant mesothelioma can take part in clinical trials of such medications, up to this day a drug with \u201cperfect selectiveness\u201c has not been discovered yet.<\/p>\n Regarding mesothelioma treatment<\/a>, chemotherapy shrinks the tumor mass, relieves the symptoms, improves the quality of life, and increases the survival time. The study published in 2020 shows that chemotherapy significantly extends survival time after the surgery.<\/p>\n Additionally, the survival time of patients who got two-line chemotherapy was doubled compared to those who used one-line. The most common first-line chemo combination was cisplatin or carboplatin combined with pemetrexed followed by the same protocol or gemcitabine as a second line. In some cases, the second line is just an extension of the first (same drugs, same doses), while other doctors decide to change the combination of drugs used in the mesothelioma treatment<\/a>. With different medication profiles to choose from, doctors can optimize chemotherapy protocol for each patient.<\/p>\n Although the health condition of some patients does not allow them to use a combination of chemotherapy drugs, studies show that two-drug combinations have supremacy over mono-component therapy. Would a three-drug combination in the mesothelioma treatment improve survival rate<\/a> even more? No, it seems. It has been tried and studies did not reveal any supremacy of the three-drug combination.<\/p>\n In numbers, one-year survival rates<\/a> between the patients (depending on whether or not they got chemo) look like this:<\/p>\n Chemotherapy is divided into cycles. Each cycle lasts for a few weeks and consists of medication and recovery period. How many of them, how often and which medications will be used is a decision of a mesothelioma specialist (depending on the type of the tumor cells, how much it has spread, how aggressive is it, overall patient health condition, etc.)<\/p>\n This kind of mesothelioma treatment<\/a> is reserved for patients who are strong enough to withstand an aggressive treatment protocol. Usually, the patient goes through the neoadjuvant therapy (this treatment shrinks the tumor before the surgery) and after the surgery adjuvant therapy protocol is prescribed (it reduces the chance of a tumor recurrence).<\/p>\n It is used for the patients who cannot go to surgery for some reason (overall health condition, tumor spread, etc.) Most often, two-line therapy is administered (if the patient’s health condition allows). Two-line therapy protocols showed supremacy over one line modalities.<\/p>\n This mesothelioma treatment<\/a> is reserved for the patients in the late stages of the condition and bad overall health. The mild chemotherapy protocol is prescribed to relieve the symptoms, improving the quality of the patient\u2019s life.<\/p>\n The drugs are administered through the I.V. line, they circulate throughout the system affecting every single cell in the body.<\/p>\n Chemotherapy is harsh. Different patients react differently to it, but there are some anticipatable side effects. In the preparation process, each patient is introduced with benefits, side, and adverse effects of chemotherapy. Here the specialist takes all necessary diagnostic tests and picks the mesothelioma treatment<\/a> modality depending on the patient\u2019s decision and medical findings. Of course, the process takes multiple visits.<\/p>\n Before inducing a chemotherapy protocol, the patient receives drugs for reducing its side effects. Medications are administered through the I.V. line, and each session usually lasts for 2-3 hours. During that time, the patient is supervised by a nurse, and blood samples are collected for further analysis. Typically, sessions are repeated every three weeks. After the entire mesothelioma treatment<\/a> protocol is completed, follow-up visits are scheduled during which the decision about further treatment is made.<\/p>\n Unlike the regional chemo and radiation therapy which affect only specific areas of the body, systemic chemo runs through the entire circulatory system, affecting all cells on its way. The most sensitive are the cells that often divide (blood, liver, skin, and epithelium cells).<\/p>\n Since the chemo affects blood cells, and indirectly food absorption, the patients almost always report mild to severe fatigue after the chemotherapy cycle. To ease it, for some it is enough to rest and sleep more than usual, while others need help in everyday tasks. In case of fatigue that significantly lowers the quality of life, correction of the chemotherapy in the mesothelioma treatment<\/a> is needed.<\/p>\n Digestive system problems are a common side effect of chemotherapy. In some patients with malignant mesothelioma, diarrhea and constipation may be caused by the spread of the tumor, while in others the irritation of the gut lining is the cause<\/a>. Taking care of the diet, water intake, and drug support if necessary, the symptom can be resolved. Typically, in days after the chemotherapy session, all intestinal symptoms<\/a> intensify, and then everything goes back to normal within a week.<\/p>\n This symptom is a direct consequence<\/a> of chemotherapy effects to the gut epithelium (the most \u201cactive\u201c tissue in the body, when it comes to the speed of division, besides blood is epithelium- it completely changes every three days!). Up to 80% of patients of this mesothelioma treatment<\/a> complain of nausea and vomiting. Depending on the primary mechanism that triggered the symptom<\/a>, it may last anywhere between a few hours and one week. Typically, nausea and vomiting become more prominent towards the end of the treatment regimen. With many effective nausea drugs available, in most of the cases, nausea and vomiting are quickly resolved.<\/p>\n Just like it damages the gut epithelium, chemotherapy affects the mouth epithelium as well. Mouth ulcers may be very unpleasant, making the food intake nearly impossible.<\/p>\n Hair follicle is a rapidly dividing structure. Shortly after the first chemo session, hair starts to fall off. Once the regimen is over, within a few weeks, it starts to regrow again. In the meantime, patients often wear wigs. Since all hairs on the body just fall off within a few days, it is advisable to take a short haircut before starting chemotherapy, to avoid seeing long hair strands on the pillow, what is an experience that is particularly frightening and unpleasant for patients on chemotherapy.<\/p>\n The white blood cells and platelet count drop are always seen in the days after the chemo session in this mesothelioma treatment<\/a>. As a result thereof, patients are prone to infections and have difficulties stopping the bleeding. Avoiding crowded and closed public spaces is highly advisable (public transportation, theater, malls, etc.) since in these places a patient could easily get infected by other people.<\/p>\n During the coronavirus outbreak in 2020<\/a>, patients under chemotherapy for mesothelioma treatment were indicated to stay at home (Source<\/a>), even when the quarantine measurements taken by different countries, started to finish gradually since May.<\/p>\n While the chemotherapy drug circulates throughout the entire body in the systemic protocol, in the case of regional chemotherapy for mesothelioma, the medications are injected into the area of carcinoma growth.<\/p>\n This approach is combined with surgical treatment. During the operation, heated to 42\u00b0-43\u00b0C (centigrades are used as a scale of measurement), the chemotherapy solution is pumped into the abdomen for up to 90 minutes (. After 60-90 minutes, surgeon drains and rinses the abdominal cavity. Compared to systemic chemo, regional treatment<\/a> has significantly fewer side effects.<\/p>\n Not all patients are indicated for this kind of treatment (only those with the diagnosis of peritoneal mesothelioma<\/a>, a condition in which cancer has spread to the lining layers of the abdomen). Before this mesothelioma treatment<\/a> technique was used, life expectancy in patients with peritoneal mesothelioma was not more than twelve months, and today (thanks to HIPEC- hyperthermic intraperitoneal chemotherapy) it is more than five years.<\/p>\n![\"chemotherapy](\"https:\/\/imedicalsociety.org\/wp-content\/uploads\/2020\/04\/2020-04-05_13-35-21.jpg\")
