Understanding Stomach Cancer Staging and Its Impact on Treatment

Radical Gastrectomy: Principles of Surgery

The stage of stomach cancer at diagnosis is the primary driver of the Treatment Details we recommend. Staging follows the TNM system, which evaluates tumor size (T), lymph node involvement (N), and metastasis (M). Early‑stage disease (Stage I‑II) often allows for curative intent surgery, while advanced stages (Stage III‑IV) may require a combination of systemic therapies before surgery can be considered.

Key Staging Components

  • T (Tumor): Describes the depth of tumor invasion into the stomach wall.
  • N (Nodes): Indicates the number and location of affected regional lymph nodes.
  • M (Metastasis): Shows whether cancer has spread to distant organs.

Accurate staging is achieved through a series of diagnostic procedures, including endoscopic ultrasound, CT/MRI scans, and laparoscopic assessment. The results guide the multidisciplinary team in selecting the most appropriate therapeutic pathway.

Stage

Typical Tumor Extent

Recommended Primary Treatment

 

Stage I

Confined to mucosa/submucosa

Surgical resection (endoscopic or gastrectomy)

Stage II

Invades muscularis propria, limited nodes

Surgery + peri‑operative chemotherapy

Stage III

Deep wall invasion, multiple nodes

Neoadjuvant chemotherapy → surgery → adjuvant therapy

Stage IV

Distant metastasis

Systemic therapy ± targeted agents, palliative care

Understanding where you fall within this framework clarifies the Treatment Details that will be most effective, helping you anticipate the sequence of interventions and the associated recovery timelines.

Surgical Options: Curative and Palliative Approaches

The Importance of Lymphadenectomy (D2 Dissection)

Surgery remains the cornerstone of curative treatment for localized stomach cancer. The specific procedure depends on tumor location, size, and stage, and is performed by experienced gastrointestinal surgeons using minimally invasive or open techniques.

Curative Surgical Procedures

  • Subtotal (Distal) Gastrectomy: Removal of the lower portion of the stomach, common for tumors in the antrum.
  • Total Gastrectomy: Complete removal of the stomach, indicated for proximal or extensive tumors.
  • Lymphadenectomy: Systematic removal of regional lymph nodes to reduce recurrence risk.
  • Robotic‑Assisted Gastrectomy: Offers enhanced precision, reduced blood loss, and faster recovery.

For patients with advanced disease where resection is not feasible, palliative surgery can alleviate symptoms such as obstruction or bleeding. Options include gastro‑jejunostomy (bypass) and endoscopic stenting.

Our surgical team follows Enhanced Recovery After Surgery (ERAS) protocols, which incorporate pre‑operative nutrition optimization, minimally invasive techniques, and early mobilization. These protocols have been shown to shorten hospital stays by up to 30 % without compromising safety.

Systemic Therapies: Chemotherapy, Targeted Therapy, and Immunotherapy

Perioperative Chemotherapy (FLOT Regimen)

Systemic treatments address cancer cells that have spread beyond the primary tumor. At Liv Hospital, we tailor chemotherapy regimens, integrate targeted agents, and consider immunotherapy based on molecular profiling.

Standard Chemotherapy Regimens

  • FOLFOX (5‑FU, leucovorin, oxaliplatin)
  • ECX (epirubicin, cisplatin, capecitabine)
  • S‑1 plus oxaliplatin (SOX)

These combinations are typically administered in cycles every two to three weeks, with dose adjustments guided by blood counts and organ function.

Targeted Therapy Options

  • Trastuzumab for HER2‑positive tumors.
  • Ramucirumab for VEGFR‑2 inhibition in refractory cases.

Testing for HER2 overexpression and other biomarkers is performed on biopsy samples, ensuring that patients who can benefit from targeted agents receive them early in the treatment course.

Immunotherapy Advances

  • Pembrolizumab for PD‑L1‑positive advanced disease.
  • Nivolumab as a second‑line option after chemotherapy.

Clinical trial participation is encouraged when appropriate, offering access to emerging therapies that may further improve outcomes.

Radiation Therapy: When and How It Is Integrated

Radiation therapy is employed as an adjunct to surgery or systemic therapy, particularly for locally advanced tumors where margins are close or positive. Advanced techniques such as Intensity‑Modulated Radiation Therapy (IMRT) and Image‑Guided Radiation Therapy (IGRT) allow precise targeting while sparing surrounding healthy tissue.

Typical Radiation Protocols

  • Pre‑operative (Neoadjuvant) Radiation: 45‑50 Gy in 25 fractions, aiming to shrink the tumor before surgery.
  • Post‑operative (Adjuvant) Radiation: 45 Gy to the tumor bed and regional nodes.
  • Palliative Radiation: Shorter courses (e.g., 20 Gy in 5 fractions) to control bleeding or pain.

Our radiation oncology team collaborates closely with surgeons and medical oncologists to synchronize treatment timing, minimizing interruptions and maximizing therapeutic synergy.

Supportive Care and Rehabilitation Services

Effective cancer care extends beyond tumor‑directed treatments. Liv Hospital offers a comprehensive supportive care program that addresses nutrition, pain management, psychological well‑being, and physical rehabilitation.

Key Support Services

  • Clinical Nutrition: Personalized diet plans to maintain weight and support healing.
  • Pain and Symptom Management: Multimodal analgesia and anti‑emetic protocols.
  • Psychosocial Support: Counseling, support groups, and stress‑reduction techniques.
  • Physiotherapy & Occupational Therapy: Early mobilization to preserve muscle strength and independence.

International patients benefit from a dedicated care coordinator who assists with travel logistics, interpreter services, and accommodation arrangements, ensuring a seamless experience throughout the treatment journey.

FREQUENTLY ASKED QUESTIONS

What are the main treatment options for stomach cancer?

The choice of treatment depends on the cancer stage and the patient’s overall health. Early‑stage disease is often managed with curative surgery, sometimes combined with peri‑operative chemotherapy. Advanced stages may require neoadjuvant chemotherapy to shrink the tumor before surgery, followed by adjuvant therapy. Targeted agents like trastuzumab are used for HER2‑positive tumors, while immunotherapy drugs such as pembrolizumab are offered for PD‑L1‑positive disease. Radiation therapy is added when margins are close or for palliation. Throughout, supportive services address nutrition, pain, psychological well‑being, and rehabilitation.

Stomach cancer is staged using the TNM system, which evaluates tumor depth (T), nodal involvement (N), and distant metastasis (M). Stage I‑II tumors are usually resectable, allowing curative surgery with or without peri‑operative chemotherapy. Stage III disease often requires neoadjuvant chemotherapy to downstage the tumor before surgery, followed by adjuvant therapy. Stage IV disease is considered metastatic; treatment focuses on systemic therapy, targeted agents, and palliative measures rather than curative surgery. Accurate staging through endoscopic ultrasound, CT/MRI, and laparoscopy guides the multidisciplinary team in selecting the optimal sequence of interventions.

The surgical approach depends on tumor location, size, and stage. For distal tumors, a subtotal (distal) gastrectomy removes the lower stomach portion, while proximal or extensive tumors may require a total gastrectomy. Systematic lymphadenectomy is performed to remove regional nodes and reduce recurrence risk. Advanced minimally invasive techniques, such as robotic‑assisted gastrectomy, provide greater precision, less blood loss, and faster recovery. When curative resection is not possible, palliative procedures like gastro‑jejunostomy or endoscopic stenting relieve obstruction or bleeding. All surgeries follow Enhanced Recovery After Surgery (ERAS) protocols to improve outcomes.

FOLFOX combines 5‑fluorouracil, leucovorin, and oxaliplatin and is widely used in both neoadjuvant and adjuvant settings. ECX (epirubicin, cisplatin, capecitabine) offers a more intensive option for fit patients. The SOX regimen pairs S‑1 (an oral fluoropyrimidine) with oxaliplatin and is popular in Asian protocols but also used internationally. Treatment cycles are typically repeated every two to three weeks, with dose adjustments based on blood counts, renal and hepatic function, and patient tolerance. Response is monitored with imaging and tumor markers, and therapy may be switched if disease progresses.

Neoadjuvant radiation (45‑50 Gy in 25 fractions) is given before surgery to shrink the tumor and improve resectability. Post‑operative (adjuvant) radiation (typically 45 Gy) targets the tumor bed and regional lymph nodes to eradicate microscopic disease. For patients with unresectable or metastatic disease, palliative radiation (e.g., 20 Gy in 5 fractions) helps control bleeding, pain, or obstruction. Advanced techniques such as Intensity‑Modulated Radiation Therapy (IMRT) and Image‑Guided Radiation Therapy (IGRT) allow precise dose delivery while sparing surrounding organs, reducing side effects.
