A nurse is caring for a 45-year-old patient with suspected gastric cancer. Which assessment finding would be most indicative of advanced gastric cancer?

## 보기

1. Mild epigastric discomfort after meals and weight loss
2. Occasional nausea and vomiting with hematemesis
3. Early satiety and bloating with dysphagia
4. Palpable epigastric mass with enlarged lymph nodes **✔ 정답**

**정답: 4**

## 해설

A palpable epigastric mass with lymphadenopathy indicates advanced gastric cancer with possible metastasis, a late-stage finding requiring immediate attention. This suggests tumor growth through the abdominal wall and spread to lymph nodes. Other options: Mild epigastric discomfort after meals is common in early gastric cancer or other GI disorders; occasional nausea and vomiting are non-specific symptoms; early satiety and bloating are typical but not indicative of advanced disease like a palpable mass.

Correct Answer Analysis

The most indicative finding of advanced gastric cancer is a palpable epigastric mass with enlarged lymph nodes. This finding represents direct tumor extension and lymphatic metastasis, which are hallmarks of locally advanced or metastatic disease.

In gastric adenocarcinoma, the tumor grows through the gastric wall and can become palpable as a firm, irregular mass in the epigastric region when it reaches sufficient size. Concurrently, malignant cells spread via lymphatic drainage to regional and distant lymph nodes. A classic example is metastasis to the left supraclavicular lymph node, known as Virchow's node, which is strongly associated with gastric cancer [2]. The presence of a palpable primary mass combined with clinically detectable lymphadenopathy indicates that the cancer has progressed beyond the confines of the gastric mucosa and submucosa, signifying stage III or IV disease. This assessment aligns with the understanding that gastric adenocarcinoma is frequently diagnosed at an advanced stage due to late presentation [1].

Distractor Analysis

Option 1: Mild epigastric discomfort after meals and weight loss are common but nonspecific symptoms. While weight loss can be a constitutional symptom of malignancy, mild postprandial discomfort is often associated with early gastric cancer or benign conditions like gastritis or peptic ulcer disease. These findings lack the specificity to indicate advanced disease with structural spread.

Option 2: Occasional nausea and vomiting with hematemesis suggests gastric outlet obstruction or tumor bleeding. Although alarming, hematemesis can occur in early-stage tumors that erode a blood vessel before deep invasion or distant metastasis occurs. This finding indicates a complication but does not definitively confirm advanced, metastatic disease in the way a palpable mass with nodal involvement does.

Option 3: Early satiety and bloating with dysphagia are concerning for a tumor located in the proximal stomach or gastroesophageal junction causing a mass effect. However, these symptoms can manifest from a locally infiltrative process without distant spread. Dysphagia specifically points to a proximal location but can occur in locally advanced, non-metastatic disease, making it less definitive for widespread dissemination than a palpable mass with lymphadenopathy.

Pathophysiology and Clinical Reasoning

The progression of gastric cancer from an intramucosal lesion to advanced disease involves transmural invasion and lymphatic dissemination. The stomach has a rich submucosal lymphatic plexus that drains to regional nodes along the lesser and greater curvatures, and eventually to distant node basins, including the supraclavicular area [2]. When a primary tumor becomes a palpable epigastric mass, it has typically invaded through the muscularis propria into the serosa, achieving a T3 or T4 pathological stage. The concurrent finding of enlarged lymph nodes provides clinical evidence of N-positive disease. This combination of a T3/T4 primary tumor with nodal metastasis is a defining feature of advanced-stage gastric cancer.

Furthermore, advanced gastric cancer can present with paraneoplastic syndromes or rare metastatic patterns. For instance, the condition can manifest through nonspecific constitutional symptoms like fever and weight loss driven by a hyperinflammatory state, as seen in secondary hemophagocytic lymphohistiocytosis . It can also present with distant, atypical metastases to soft tissue or the orbit, causing symptoms like diplopia, which are easily mistaken for benign conditions [1]. These varied presentations underscore why a direct, physical finding of tumor spread—a palpable mass with nodal involvement—is the most clinically definitive indicator of advanced disease among the options provided.References (research sources)

## 임상 시나리오

Advanced Gastric Cancer AssessmentRecognizing Signs of Metastatic Disease
A palpable epigastric mass with enlarged lymph nodes is the most specific clinical finding for advanced gastric cancer. This indicates the tumor has extended through the gastric wall and metastasized via the lymphatic system.

Assess for distant node involvement, specifically Virchow's node in the left supraclavicular area. Early symptoms like epigastric discomfort or weight loss are nonspecific and often lead to delayed diagnosis.

CautionA palpable mass with lymphadenopathy strongly suggests Stage III or IV disease. Immediate referral for confirmatory imaging and biopsy is critical, as gastric cancer often presents late.
