All patients with tumors that can be resected should undergo surgery. As many as 15% of selected stage III patients can be cured by surgery alone, particularly if lymph node involvement is minimal (<7 lymph nodes).
Caregivers need help and emotional support.
A caregiver responds in his or her own way to the cancer patient's diagnosis and prognosis. The caregiver may feel emotions that are as strong as or stronger than those felt by the patient. The caregiver's need for information, help, and support is different from what is needed by the patient.
The life of a family caregiver changes in many ways when cancer is diagnosed. These changes affect most parts of life and continue after treatment ends.
Postoperative chemoradiation therapy may be considered for patients with stage III gastric cancer. A prospective multi-institution phase III trial (SWOG-9008) evaluating postoperative combined chemoradiation therapy versus surgery alone in 556 patients with completely resected stage IB to stage IV (M0) adenocarcinoma of the stomach and gastroesophageal junction reported a significant survival benefit with adjuvant combined modality therapy.[Level of evidence: 1iiA] With a median follow-up of 5 years, median survival was 36 months for the adjuvant chemoradiation therapy group as compared to 27 months for the surgery-alone arm (P = .005). Three-year overall survival (OS) and relapse-free survival rates were 50% and 48%, respectively, with adjuvant chemoradiation therapy versus 41% and 31%, respectively, for surgery alone (P = .005). Because distant disease remains a significant concern, the aim of the Cancer and Leukemia Group B study (CALGB-80101), which is now closed, was to augment the postoperative chemoradiation regimen used in the SWOG-9008 trial, for example, and the preoperative chemotherapy and chemoradiation therapy regimen used, for example, in the RTOG-9904 trial, which is now completed.
Investigators in Europe evaluated the role of preoperative and postoperative chemotherapy without radiation therapy. In the randomized phase III trial (MRC-ST02), patients with stage II or higher adenocarcinoma of the stomach or of the lower third of the esophagus were assigned to receive three cycles of epirubicin, cisplatin, and continuous infusion 5-fluorouracil (ECF) before and after surgery or to receive surgery alone. Compared with the surgery group, the perioperative chemotherapy group had a significantly higher likelihood of progression-free survival (hazard ratio [HR] for progression, 0.66; 95% confidence interval [CI], 0.53–0.81; P < .001) and of OS (HR for death, 0.75; 95% CI, 0.60–0.93; P = .009). Five-year OS was 36.3%; 95% CI, 29 to 43 for the perioperative chemotherapy group and 23%; 95% CI, 16.6 to 29.4 for the surgery group.[Level of evidence: 1iiA]
