RESUMEN
The patient was a 70-year-old woman, who had undergone total gastrectomy and splenectomy with D2 lymph node dissection, for stage II gastric cancer. We admitted S-1 of 80 mg/day in adjuvant chemotherapy on postoperative day 28. There were no adverse events for one week, and she was discharged. Severe diarrhea occurred 6 days following discharge, but she continued to take S-1. Two weeks after discharge, she visited our hospital, suffering from severe dehydration (grade 4), leucopenia (grade 4)and thrombocytopenia (grade 3). Unfortunately, she died of lung edema and multiple organ failure 28 days after chemotherapy. We measured the mRNA expression level of dihydropyrimidine dehydrogenase (DPD) of the patient's liver by the Dannenberg Tumor Profile method. The expression level of DPD was significantly low, so we suggested that the severe bone marrow suppression might have been caused by the disordered metabolism of 5-FU.

BACKGROUND/AIMS: Although extended lymphadenectomy for thoracic esophageal cancer is widely practiced in Japan, solitary supraclavicular lymph node recurrence (SCLR) has often become a problem. This study was designed to evaluate the survival and clinical benefit of salvage cervical lymphadenectomy. METHODOLOGY: Between 1989 and 2001, 153 patients underwent esophagectomy for esophageal cancers. SCLR was identified in 5 (3.7%) patients and these five patients were examined retrospectively. RESULTS: Surgical treatment was performed intensively for all patients. Two patients showed longterm survival for 7 years 3 months and 4 years, respectively. Four patients belonged to the good prognostic group but the other patient had poor prognosis from the viewpoint of both the pathological metastatic lymph node number and disease-free interval (DFI). There were no local recurrences but were a recurrent laryngeal nerve palsy in three patients associated with treatment. CONCLUSIONS: Salvage cervical lymphadenectomy for SCLR should be performed positively by selecting each case carefully. Indication must be weighed against increased morbidity considering such indicators as the extent of metastatic lymph node numbers and DFI.

BACKGROUND/AIMS: Little is known about the clinicopathological features of intermediate-stage T2 gastric cancer, defined as tumors invading the muscularis propria or subserosa. METHODOLOGY: Of 808 patients with gastric cancer, 210 patients (25.9%) who underwent gastrectomy for T2 gastric cancer were selected for this retrospective study. The clinicopathologic findings of these patients were analyzed retrospectively from their hospital records. RESULTS: Of all 808 patients with gastric cancer, 73 patients (9.0%) had tumors invading the muscularis propria (mp). The remaining 137 patients (16.9%) had tumors invading the subserosa (ss). Compared with ss gastric cancer, mp gastric cancer was associated with smaller tumor size, an absence of lymphatic spreading, and hematogenous and late recurrence [disease-free interval: 654.5 days (mp) vs. 365.5 days (ss)]. Univariate analysis of cases with curative operations showed that lymphatic invasion, and lymph node metastasis were significant prognostic factors in patients with T2 gastric cancer. Further examination by multivariate analysis demonstrated that pN2 or higher as classified by both the JCGC (Japanese Classification of Gastric Cancer) and the TNM lymph node staging systems was a predictor of poor prognosis. CONCLUSIONS: JCGC and TNM lymph node staging systems were the most reliable prognostic factors for T2 gastric cancer. Close follow-up should be required for patients with stage pN2 or higher gastric cancer. Long-term follow-up should be required for mp cancers, in particular.

BACKGROUND/AIMS: The latest TNM classification (5th edition) changed the definition of nodal staging from the anatomical localization to the total number of metastatic lymph nodes. This study was designed to evaluate and compare the prognostic significance of nodal staging between the two widely known staging systems, the TNM classification (TNM) and Japanese Classification for Gastric Cancer (JCGC). METHODOLOGY: A total of 582 patients who underwent curative gastrectomy with extended lymphadenectomy for gastric cancer were reviewed retrospectively from hospital records. Based on the localization of metastatic nodes according to the JCGC and the total positive node number according to TNM, the patients were divided into subgroups and their prognoses compared. RESULTS: Lymph node metastasis was found in 189 of the 582 patients (32.5%). Both nodal staging systems were found to be significant prognostic factors by multivariate analysis. A prognostic analysis of the patients by subdivision with the two staging systems indicated that the nodal staging system in TNM was more homogenous than that of the JCGC. CONCLUSIONS: The nodal staging system of the TNM classification is superior to that of the Japanese Classification of Gastric Cancer, because it is simple, reproducible and homogeneous.
