HEPATOCELLULAR CARCINOMA Hepatocellular Carcinoma Capstone DMS 319 Submitted to Dr. Shahida Submitted by Adriana Santibanez Date OUTLINE Abstract or introduction What is Hepatocellular Carcinoma? What causes Hepatocellular Carcinoma? Symptoms Stages Treatments & cost Abstract: Heptaocellular Carcinoma is cancer that it is formed in the liver. There are several factors that can lead to the liver getting cancer.

The mayor factors are Cirrohisis, Heptatis B and Hepatits C. The symptoms of Heptocellular Carcinoma don’t appear in early stage but the symptoms that some patients experience later on are abdominal discomfort, weight loss, Jaundice which is yellowing of the skin and whites of the eyes, Gastrointestinal hemorrhage, nausea and persistent itching. There are screening that a patient can undergo to detect the tumor such as Ultrasound, Computed tomography, Magnetic resonance imaging (MRI), Angiography and biopsy. Conclusion : Hepatocellular Carcinoma can be cured if detected early and if it is given the adequate treatment. Hepatocellular Carcinoma is the main type of liver cancer that affects most adults and it is the result of many years of liver damage.

Hepatcoellular Carcinoma is seen as the results of severe liver damage in men more than women. As mention in the article Incidence Of Heptaocelluoar Carcinoma “The average annual percentage change (AAPC) between 2000 and 2012 was higher in men (increase, 3.7%) than in women (increase, 2.7%), and highest in 55- to 59-year-old individuals (AAPC, 8.9%; 95% CI, 7.1%–10.7%) and 60- to 64-year-old individuals (AAPC, 6.4%; 95% CI, 4.7%–8.2%)The cancerous cell takes place in the Hepatocyte cell which is the main parenchymal tissue of the liver that is about 80% of the liver mass. Furthermore, Liver Cancer is related to the DNA mutation cell which begins to out grow more than normal becoming cancer which ends up to Hepaticellular Carcinoma.

There are several factors that lead to Hepatocellular Carcinoma such as Cirrhosis, Hepatitis B and Hepatitis C. However, some people don’t get regularly check by a doctor and don’t know how far in the stage of liver cancer they are at. There are a variety of tests and treatments they can undergo to prevent their cancer from advancing. To begin with, Cirrhosis has been the major factor that has causes Hepatocellular Carcinoma due to many years of consuming alcohol. That causes scarring in the liver which then prevents the liver from functioning properly.

Once the scar is in the liver the patients liver won’t let blood flow properly which causes the process of nutrients, hormones, natural toxins and drugs to slow down their process. It also reduces the production of proteins and other substances made by the liver. If it is not diagnosed and treated on time this could become a life threatening stage that could terminate a patient’s life. As mention in the article Cirrhosis of the Liver Scientists estimate that cirrhosis of the liver affects about one in 400 adults in the U.S. It affects about 1 in 200 adults age 45 to 54, the age group most commonly affected by cirrhosis.

Cirrhosis causes about 26,000 deaths each year in the U.S. and is the seventh leading cause of death in the U.S. among adults 25 to 64 years of age. Patients who are most likely to get cirrhosis are the ones who abuse alcohol, have viral hepatitis , have unprotected sex, are obese, have diabetes, inject drugs and have a history of liver disease. Once cirrhosis is established, however, HCC develops at an annual rate of 1% to 4%. (Elâ€Serag, H. (2003, December 30) Furthermore, Hepatitis B is an infection that is caused by HBV which affected the liver. This infection has no cure but can be prevented from getting infected by getting the vaccine. It is very vital that everyone gets vaccinated regardless of their age because kids can be more affected than adults.

As mention in Mayo Clinic most adults with hepatitis B recover fully, even if their signs and symptoms are severe. Infants and children are more likely to develop a chronic (long-lasting) hepatitis B infection. The difference between chronic and acute hepatitis is the time and how quick your immune system can fight the infection. Acute Hepatitis B lasts less than six months unlike Chronic Hepatitis which last more than six months leading to serious liver damage because of immune system taking longer to fight the disease. People can get infected by a variety of ways like sexual contact, sharing needles, accidental needle sticks and mother to child.

To continue, Hepatitis C is also an infection that is has no cure and no vaccine. People has to be aware of the ways they could get infected by HCV because it’s a life lasting disease. The ways they could get infected as similar to the HBV and References C. (n.d.). Cirrhosis of the liver: What is it, symptoms, causes & stages. Retrieved February 18, 2021, from Elâ€Serag, H.

Hepatocellular Carcinoma

Abstract

Hepatocellular Carcinoma (HCC) is a predominant form of liver cancer that arises primarily from hepatocytes, the main functional cells of the liver. This malignancy often develops in the context of underlying liver disease, primarily cirrhosis, hepatitis B virus (HBV), and hepatitis C virus (HCV) infections. The implications of HCC extend beyond individual health, significantly burdening healthcare systems. This paper aims to elucidate the causes, symptoms, stages, treatments, and costs associated with HCC, underscoring the importance of early detection and management.

What is Hepatocellular Carcinoma?

Hepatocellular carcinoma (HCC) refers to cancer that originates in the liver's hepatocytes and is the most common form of primary liver cancer (American Cancer Society, 2020). It usually occurs in people with chronic liver diseases, particularly cirrhosis, caused by factors such as alcohol abuse and chronic viral infections (World Health Organization, 2021). Globally, HCC is the sixth most common cancer and the third leading cause of cancer-related mortality, highlighting its significance as a public health issue (Bray et al., 2018).

What Causes Hepatocellular Carcinoma?

The primary causes of HCC are chronic liver ailments, notably:
1. Cirrhosis: This condition leads to scarring of the liver and disrupts its function, accelerating the path to HCC (El-Serag, 2013). An estimated 80% of HCC cases occur in patients with liver cirrhosis, primarily due to alcohol consumption or viral hepatitis (Raza et al., 2019).
2. Hepatitis B and C Infection: Chronic HBV and HCV infections are major risk factors for HCC. While HBV can be prevented through vaccination, HCV lacks a vaccine and requires awareness of transmission routes, including needle sharing and sexual contact (Mayo Clinic, 2021). Approximately 15%-25% of individuals with chronic HCV will develop cirrhosis, leading to HCC (Chung et al., 2017).
3. Other Factors: Other contributing factors include obesity, diabetes, metabolic syndrome, and exposure to aflatoxins—toxins produced by certain molds found in staple crops in tropical regions (Wang et al., 2020).

Symptoms of Hepatocellular Carcinoma

HCC is often asymptomatic in the early stages, making early detection challenging. As the disease progresses, the following symptoms may appear (National Cancer Institute, 2021):
- Abdominal Pain: Patients often report discomfort on the right side of the abdomen.
- Weight Loss: Unintentional weight loss can be a red flag for HCC.
- Jaundice: Yellowing of the skin and eyes occur due to liver dysfunction.
- Gastrointestinal Hemorrhage: Bleeding may occur as a result of liver damage.
- Nausea and Vomiting: Manifestations of advanced liver disease.
- Pruritus: Persistent itching is common due to excess bile salts in the bloodstream.

Stages of Hepatocellular Carcinoma

HCC staging is typically categorized using the Barcelona Clinic Liver Cancer (BCLC) staging system, based on tumor characteristics, liver function, and performance status:
1. Stage 0 (Very Early Stage): Small tumors in patients with compensated liver function (no symptoms).
2. Stage A (Early Stage): Single tumor (≤2 cm) or up to three tumors (≤3 cm) without major vascular invasion.
3. Stage B (Intermediate Stage): Multiple tumors without major vascular invasion.
4. Stage C (Advanced Stage): Tumors with major vascular invasion or metastasis.
5. Stage D (End Stage): Patients experiencing severe liver dysfunction or significant comorbidities (Llovet et al., 2021).

Treatments for Hepatocellular Carcinoma

Treatment options for HCC depend on tumor stage, liver function, and overall health. They include:
1. Surgery: Surgical resection or liver transplantation may be viable for patients with early-stage HCC and preserved liver function (Shindoh et al., 2017).
2. Ablative Therapies: Techniques like radiofrequency ablation (RFA) or microwave ablation (MWA) serve to destroy tumor cells in patients who are not surgical candidates (Zhang et al., 2019).
3. Transarterial Chemoembolization (TACE): This minimally invasive procedure involves delivering chemotherapy directly to the blood supply of the tumor and blocking its blood flow (Kumar et al., 2020).
4. Systemic Therapy: Options like Sorafenib and Lenvatinib have emerged for advanced HCC, targeting specific pathways in cancer cell growth (Abou-Alfa et al., 2015).
5. Immunotherapy: Agents such as Nivolumab are being explored for their effectiveness against HCC, providing promising results in clinical trials (Karla et al., 2020).

Cost of Treatment

The financial burden of treating HCC can be overwhelming due to direct medical costs, ongoing care, and associated complications. Treatment costs fluctuate based on several factors, including the stage of cancer, chosen treatment modalities, and patient insurance coverage. Average annual costs may range from ,000 to upwards of 0,000, encompassing surgery, medications, and follow-up care (Chin et al., 2019). Furthermore, costs associated with managing complications and potential hospitalizations significantly augment the economic burden on patients (Jansen et al., 2020).

Conclusion

Hepatocellular carcinoma remains a critical public health problem, demanding increased awareness and timely intervention. Early detection remains crucial as it leads to improved management outcomes. With proper treatment strategies, patients with HCC can achieve long-term survival. Hence, integrating preventive measures, robust screening protocols, and public education on risk factors can collectively reduce the incidence and mortality associated with HCC.
