Liver cancer
The Function of the Liver and Complications Associated with Liver Cancer
The liver is one of the body’s largest internal organs and performs over five hundred crucial tasks for our wellbeing. From filtering toxins out, producing bile to aid digestion and store energy efficiently; to regulating cholesterol and hormone levels in addition to blood clotting mechanisms – any disease affecting this vital organ could prove devastatingly hazardous for one’s wellbeing. It can lead to loss of significant reserves that the human body depends on; cancer of the liver leads to dysfunction, which causes immense complications such as liver failure, disorders of bleeding, and other degenerative metabolic disorders.
Liver Cancer Causes
Liver cancer starts developing in the tissues of this crucial organ. According to many researchers and doctors worldwide, it happens when there is a genetic mutation causing normal liver cells to change tendentiously into neoplastic tumours. Although not often diagnosed across populations in most countries, it still poses a risk for early deaths alongside other chronic illnesses. It therefore qualifies together with heart diseases, diabetes, both being highly fatal without aid or caring attention. The key understanding working towards raising awareness using education – knowing what causes this problem, which could easily isolate structures like hepatitis, is simple enough, while other steps helping monitor progression lead treatment put to make – lose chances greatly helps resolving iss run almost no longer get stifled smart daily showered public raisers helped solve.
Categories Associated With Primary And Secondary Liver Tumours
Comprehensively regarded under two distinct folds are primary, whereas secondary fill formations are tackled quite succinctly:
Primary Liver Cancer: Primary liver cancer occurs directly within the liver itself and most commonly arises as Hepatocellular Carcinoma, or HCC, from liver cells known as hepatocytes, although Intrahepatic Cholangiocarcinoma and angiosarcoma – rare forms that arise in blood vessels – also exist.
Secondary or Metastatic Liver Cancer: Cancers that originate elsewhere such as colon, breast or lung can spread metastatically to invade and eventually infiltrate into the liver. Secondary liver cancer forms more frequently than primary liver cancer in the context of already having concurrent illnesses elsewhere in the body.
About the causes and factors of these diseases:
Chronic damage and inflammation of the liver typically give rise to liver cancer over time. Most prevalent drivers can be listed as follows:
Liver Cancer Symptoms
One key difficulty with liver cancer is that neoplastic changes often appear asymptomatic for prolonged periods.
Abdominal discomfort
Unanticipated weight reduction
Extreme tiredness and muscle weakness
Decreased appetite
Jaundice (skin and eye yellowing)
Nausea and emesis
Urine darkening and stool lightening
Lower limb swelling (oedema) or ascitic fluid accumulation in the abdomen
The symptoms generally observed after the onset of significant progression pose a challenge to early intervention, but it is urgent.
Diagnosis of liver cancer
Assessment includes a medical history review, physical assessment, imaging studies, lab work, and evaluations, which comprise:
Specific Blood Tests: These include both a comprehensive metabolic panel as well as testing for elevated AFP levels – often found in liver tumors – within blood samples taken for test.
Imaging Studies: Ultrasound scans, CT scans and MRI can all assist in the detection and localization process.
Hepatic Biopsy: A microscope examination is done following tissue sample extraction to confirm the malignancy type.
Staging: Selection of appropriate treatment requires the assessment of the cancer’s extent. This may involve X-ray imaging of the chest and bone scans to evaluate whether metastasis has occurred.
Is Liver Cancer Curable?
Let’s address the most significant issues point by point as outlined in the bullet points:
Diagnosis type: The management of a few types of liver cancer is easyer comparatively such as hepatocellular carcinoma (HCC) is easier compared to cases where it has metastasised from other organs.
Stage of diagnosis: Liver cancer, just like any other cancer, is easier to manage if it is in its early stages. If diagnosed during the later stages, however, the prognosis is more difficult to navigate.
Type of treatment: Treating cancers like liver cancer is more effective if done immediately after diagnosis. With the right choice of treatment protocol, if treatment is delayed, there is increased difficulty in navigating the disease.
Proper treatment method: Treatment is more effective if specific to the case, tailored around the latest treatments, such as advanced therapies mentioned below.
Liver Cancer Treatment
The presence of liver cancer is treated based on its type, size, location, stage, and also taking into account the patient’s general health. The main treatment options include: A. Traditional Treatments, B. Advanced and alternative treatment for liver cancer
A. Traditional Treatment for Liver Cancer
1. Surgical Procedures
Liver Resection: In the case of a tumour that can be surgically removed along with a segment of liver tissue, and assuming the remaining liver is sufficiently healthy, then resection will be performed.
Liver Transplantation: This procedure is suitable for certain patients presenting with early-stage HCC and significant cirrhosis or hepatic impairment. This also involves the orthotopic replacement of the organ.
2. External Beam Radiation Therapy
External beam radiation therapy was invented in the 1890s using machines such as linear accelerators to direct radiation beams at cancerous regions of a body.
External beam radiation therapy utilizes high-energy radiation waves that may help shrink cancer tumours or alleviate pain at later stages.
Radiation from outside sources directed toward an area of cancer can help kill cancerous cells while also harming healthy tissues, but must be used carefully as there is the possibility that healthy tissues could also be destroyed in this process.
External Beam Radiation Therapy can also be used as a preventive therapy, which is done after the surgical removal of a tumour.
3. Systemic Chemotherapy
Systemic chemotherapy was invented in the 1940s and has been used since then.
Systemic chemotherapy is a drug therapy that is used to destroy cancer cells all over the body. Systemic chemotherapy is given intravenously through a needle inserted into a vein, which goes into the central bloodstream of the body. This may have a lot of side effects on the patient as it affects both cancerous cells and the healthy cells of the human body. The side effects are different depending on different scenarios, like the drug used, the dosage of the drug, and other physical parameters.
B. Advanced Treatments for Liver Cancer
As compared to traditional therapies, there are a lot of new and advanced treatments invented and accepted worldwide for treating cancer, as new research and developments are being done worldwide. Advanced and alternative treatments, as compared to traditional treatments, have fewer side effects or no side effects for treating cancer in different stages. Researchers worldwide have done a lot of advanced research and succeeded in finding advanced therapies and treatments for cancers. The examples of a few of which are described below:
1. Microinvasive Therapies and Surgeries/ microinvasive therapies for cancer / microinvasive surgery for liver cancer / treating liver cancer microinvasively
Microinvasive therapies mean the therapies which are characterised by a very slight invasion into the body used to reach the side of the affected area, for example, microscopic surgeries.
There are a lot more new inventions for treating cancer micro invisibly invented in the past few years, such as:
- Nano knife for Liver cancer
U.S. and European authorities issued their approval in December 2012, and later in June 2015, the FDA of China also sanctioned the use of Non-thermal ablation techniques, more commonly known as NanoKnife ablation or Irreversible Electroporation (IRE) for clinical purposes. Reports suggest that the Nanoknife is useful in treating tumours residing in solid organs like the pancreas, liver, lungs, kidneys and prostate. Its efficacy is unmatched, particularly with tumours abutting gallbladders, bile ducts, and ureters. Fuda Cancer Hospital holds the record in Asia for the most number of cases treated, as it was the first hospital to use Nanoknife in Asia. Learn more….
- Cryosurgical Ablation for liver cancer
Cryosurgical Ablation (also known as Cryosurgery or Cryo-ablation) is possibly the most promising among so many clinically used ablation treatments. It is carried out by hardening the excrescence kerchief with extremely low temperature. Within the tissue of the wart, ice plates begin to develop after the tip’s temperature falls below – 40°C. The process involves the death of the tumour cell, causing it to undergo necrosis within the excrescence kerchief. Thus, we can assume that progressive failure of microcirculation under cryosurgery implies porous vessel walls of endothelial caste destruction, interstitial oedema, platelet aggregation, microthrombi and finally obliteration in the vascular bed.
The theory was posited that the weak system of these people could be revived during cryosurgery. After cryosurgery, the immune system may have been involved because it could destroy those residual excrescent keratosis and metastases not destroyed by cryosurgery alone. This concept was termed “cryo-immunological response”. Procedure for Cryosurgery Depending on the site and size of a lesion, cryotherapy may be carried out through intraoperative routes or percutaneous endoscopic routes. During the procedure, the tumour is opened with an open incision or under image guidance, and is fitted with 24 mm probes, which are cooled using Argon helium freezing and warming systems in two to three cycles of freezing followed by thawing.

2. Targeted Therapies
- Targeted Chemotherapy :
I. Microvascular Interventional Chemo
Transcatheter tumour vascular intervention therapy encompasses the following procedures: transcatheter arterial infusion chemotherapy (TAI), transcatheter arterial embolisation (TAE), and transcatheter arterial chemoembolization (TACE).
TAI is conducted by placing an arterial pump under the skin and infusing it with drugs or by direct infusion of chemotherapy into the artery supplying blood to the tumour. This is done to increase the drug concentration within the tumour and induce a better tumour response. In doing so, there is a lower concentration of the drug in the systemic circulation, which reduces the more toxic side effects on other organs. Learn more….
II. Chemo using Targeted Drugs
there are certain advanced and targeted drugs invented in past few years which are used systemecally in chemo therapy the drugs which avoid or reduces chances of side affects by protecting health cells in human body resulting in low side affect or no side effect systemic chemo therapy which helps the patient to recover faster and reduce the risk of side affects.
- Targeted Radiation Therapy (Brachytherapy or Radioembolization)
One of the most effective cancer treatments is Brachytherapy using Iodine-125 or Palladium-103 seeds. It is less invasive than surgery, and patients typically require less recovery time than with other treatments. For example, patients with prostate cancer can have brachytherapy done as a same-day outpatient surgery. In addition, most patients can return to their normal routine within a few days. The time taken for the procedure is also quite reasonable, with seed implantation taking 45 minutes to 1 hour. Compared to Palladium-103, Iodine-125 brachytherapy tends to result in lower doses of radiation exposure. Most prostate cancers are indolent tumours and respond well to Iodine-125’s longer half-life. The 125 iodine seeds, which have a half-life of 59 days, emit short bursts of gamma radiation. The seeds placed into malignant tissues emit radiation that selectively destroys cancerous cells while sparing healthy tissues. Sophisticated 3D CT/MRI rendering allows for the precise calculation of the radiation dose required to kill neoplastic cells while avoiding healthy tissues. The radiation dosage, however, is still calculated conservatively to minimise exposure to any healthy surrounding tissue. Thus, the number and distribution of the seeds to be placed are carefully predetermined. Learn More….
- Stem Cells Therapies and Immunotherapies for Liver Cancer
The latest and most advanced treatment for cancer, also known as the future of cancer treatment without side effects, is stem cell therapy or immunotherapy. These therapies basically improve the body’s immunity to fight against unwanted cancer cells growing in the body without any harm to the healthy cells of the human body, as well as promoting the function and capacity of vital organs of the body to work at their highest capacity.
The active practices of immunotherapy using immunological approaches to treat malignant tumours have advanced due to the innovations within immune checkpoint inhibitor therapy and chimeric antigen receptor T-cell immunotherapy (CAR-T). Recently, several works documented cases of survival prolongation when combining immunotherapy with a minimally invasive intervention or other traditional methods. For instance, immune checkpoint inhibitors (anti-PD-1 antibodies) used as primary therapeutic agents in many tumours are finding great synergy with minimally invasive approaches, which enhance patient survival, and more and more patients can benefit.

Prevention and Lifestyle Management
Reducing risk factors helps in the primary prevention of liver cancer:
Hepatitis B immunisation
Sexual abstinence and no sharing of needles to prevent hepatitis C
Moderate drinking
Physical fitness, along with a healthy weight
Liver disease patients require routine follow-up appointments with their physician for liver health assessments.
Utilizing appropriate storage techniques for grains, nuts and legumes helps limit exposure to aflatoxins.
People at high-risk, such as those suffering from cirrhosis or chronic hepatitis, should receive routine screening tests.
Prognosis and Survival Rates
Each patient’s prognosis for liver cancer varies dramatically based on its stage at diagnosis. While surgical excision or transplantation can cure early-stage cancers, late symptoms often signal advanced-stage cancer diagnosis which lowers survival rates significantly; five year survival for early stage hepatocellular carcinoma is estimated at 30-35% but decreases rapidly as disease spreads outside of liver tissue.
Conclusion
Liver cancer presents various pathological and clinical complexities. Understanding risk factors as well as early detection increases treatment opportunities; systematized reviews coupled with active monitoring provide preventative strategies for individuals with advanced liver illnesses; adopting adaptable guidelines further lower the chances of encountering this form of cancer.
