Introduction

Stomach cancer, also known as gastric cancer, is a typeof cancer that beginsin the stomach lining. It is one of the leading causes of cancer-related deaths worldwide, making its understanding and treatment crucial. Chemotherapy is one among the many therapeutic options available in the fight against this tough cancer.

Understanding stomach cancer 

Risk factors and causes

Stomach cancer develops from aberrant cell development in the stomach lining. While the precise cause (aetiology) is frequently unknown, some variables enhance the likelihood of having this malignancy. Infection with the Helicobacter pylori bacteria, a family history of stomach cancer, smoking, and a diet heavy in smoked or salted foods are all risk factors.¹

Typical symptoms

Recognising the signs of stomach cancer is critical for early detection. Patients may experience prolonged indigestion, stomach discomfort, accidental weight loss, and a feeling of fullness, even after a small meal. Since these symptoms can be vague, it is important to seek medical help for persistent pain.

Diagnostic techniques

An accurate and timely diagnosis is essential for effective therapy. Some common diagnostic techniques for stomach cancer include:

• Endoscopy involves inserting a flexible tube with a camera via the mouth to view the stomach lining.
• Biopsy: During an endoscopy, tissue samples are obtained to confirm the existence of cancer cells¹
• Computed Tomography (CT) scans, X-rays, and Magnetic Resonance Imaging (MRIs) can assist in detecting the extent of cancer and whether it has spread to other organs.

Chemotherapy fundamentals 

Chemotherapy is a systemic treatment that employs medications to target and eradicate cancer cells throughout the body specifically. It plays an important role in the overall management of stomach cancer.

Definition and goal

Chemotherapy involves prescribing medications that prevent cancer cells from growing and dividing. Its key objectives are to shrink tumours, prevent the spread of cancer, and destroy cancer cells that may linger after surgery.²

The process of chemotherapy

Chemotherapy medications can be cytotoxic, causing DNA damage in cancer cells, or cytostatic, preventing cancer cellsfrom dividing. By attacking rapidly dividing cells, chemotherapy aims to stop cancer's unchecked development.

Various chemotherapy drugs used to treat stomach cancer

Many chemotherapy medicines are used, either alone or in combination, to treat stomach cancer. Fluorouracil, cisplatin, and docetaxel are examples of common medications.² The medications used are determined by the precise features of the malignancy and the patient's general condition.

• Fluorouracil (5-FU): This drug interferes with DNA synthesis, inhibiting cancer cell growth.
• Cisplatin: is a platinum-based medication that destroys cancer cells' DNA and prevents them from multiplying.
• Docetaxel: This drug disrupts microtubule formation, which is required for cell division, resulting in cell death.²

Chemotherapy indications in stomach cancer

Stomach cancer stages where chemotherapy is advisable

The stage of stomach cancer influences the decision to suggest chemotherapy. Chemotherapy may be given before surgery (neoadjuvant) in the early stages (I and II) to decrease tumours and facilitate surgical removal. Chemotherapy is frequently used in advanced stages (III and IV) to control the illness, reduce symptoms, and enhance overall survival.³

In conjunction with other therapies (surgery, radiation)

In certain circumstances, chemotherapy is given before surgery to decrease tumours and make them more receptive to surgical removal. This approach increases the likelihood of a successful operation and can be combinedwith radiation therapy.

• Adjuvant Therapy: Adjuvant chemotherapy may be indicated following surgery to eradicate any leftover cancer cells and lower the chance of recurrence. This is especially important when the malignancy has spread to the deeper layers of the stomach wall or surrounding lymph nodes.
• Palliative Chemotherapy: When surgery is no longer an option for curing cancer, chemotherapy can be used to control symptoms, slow disease progression, and improve the quality of life. This approach is often combined with supportive care approaches.³

The chemotherapy procedure

First consultation and treatment plan

The first step in starting chemotherapy for stomach cancer is a key consultation. This stage is a joint effort involving the patient, oncologist, and healthcare staff. During this consultation, the oncologist evaluates the patient's medical history, explains the intricacies of the cancer diagnosis, and offers possible treatment choices. Factors such as the stage of cancer, general health, and individual preferences influence a personalised treatment plan.³

Modalities of administration

Chemotherapy by mouth

Some chemotherapy treatments for stomach cancer are available in pill form, allowing patients to take them at home. This method is convenient but requires strict adherence to the prescribed schedule.⁴

Chemotherapy administered intravenously

Chemotherapy drugs are administered directly into the bloodstream via intravenous (IV) injection. This procedure guarantees that the medication is distributed quickly and effectively throughout the body. Sessions are usually held in a clinic or hospital and are supervised by experienced healthcare experts.

Treatment schedule and duration

The treatment strategy is adapted to the patient's individual needs and the specific nature of their cancer. Factors such as the type of chemotherapy drugs, dosage, and frequency of treatment sessions are all carefully considered. The duration of chemotherapy varies depending on the response of the malignancy, but it usually consists of numerous rounds spread out across weeks or months. Regular imaging and diagnostic tests help evaluate the treatment's effectiveness.⁴

Adverse reactions and their management

Typical chemotherapy adverse effects

While chemotherapy is an effective cancer treatment, it can also cause adverse effects. Common symptoms include nausea, exhaustion, hair loss, and low blood cell counts, which raise the risk of infection and bleeding.

Adverse effect reduction strategies

• Anti-Nausea drugs: Prescription drugs can assist in managing chemotherapy-induced nausea and vomiting.
• Nutritional assistance, pain control, and mental counselling all contribute to general well-being throughout treatment.
• Blood Cell Growth Factors: These drugs boost blood cell synthesis, lowering the risk of infection and anaemia.⁴

The importance of communicating with the healthcare team

It is critical to have open contact with the healthcare staff. Immediate reporting of any adverse effects enables rapid intervention and revision of the treatment strategy. Regular check-ups and consultations with healthcare specialists build a collaborative and supportive atmosphere.

Follow-up and monitoring

Routine check-ups throughout chemotherapy

Regular check-ups are essential for effective stomach cancer treatment. These appointments allow healthcare experts to assess therapy response, monitor side effects, and make necessary adjustments. Patients should participate fully in these visits, offering information about their experiences and well-being.⁵

Imaging and laboratory examinations

Imaging, such as CT scans, X-rays, and laboratory testing, are critical for tracking the growth of stomach cancer and assessing the effectiveness of treatment. These diagnostic tools help healthcare providers make informed decisions regarding long-term treatment plans.

Treatment plan modifications based on progress

The dynamic nature of cancer treatment frequently requires changes to the initial strategy. Monitoring allows healthcare providers to modify chemotherapy procedures based on the tumor's reaction and the patient's general health, ensuring the most effective and appropriate treatment.⁵

Supportive care 

Nutritional advice throughout chemotherapy

Chemotherapy might affect appetite and nutrient intake. Nutritional counselling help patients maintain proper nutrition, supporting overall health and aiding recovery. Personalised dietary adjustments provide the strength required to withstand therapy.

Emotional and psychological assistance

Cancer and its treatment have a significant emotional impact. It is critical to provide channels for emotional and psychological assistance, such as counselling or support groups. A multidisciplinary team of psychologists and social workers can address patients' needs and promote mental well-being.

The value of a multidisciplinary approach

Stomach cancer treatment extends beyond the confines of the oncologist's office. An interdisciplinary approach involves collaboration among oncologists, surgeons, dietitians, psychologists, and other professionals. This cooperation ensures that patients receive complete treatment that covers all aspects of their experience.⁵

Success stories and obstacles

Testimonials from patients
