This study was done to define the prognostic role of some clinical and pathologic variables in patients with carcinoma of the stomach who underwent a curative subtotal gastrectomy for cancer located at the lower two-thirds of the stomach. An univariate and multivariate analysis, according to Cox's regression model, was retrospectively performed upon 361 patients operated upon at the Istituto Nazionale Tumori of Milan from 1965 to 1979 by a curative subtotal gastrectomy. Data were stored by an IBM 4331 computer. Several factors were taken into consideration: age, sex, site and size of tumor, gross appearance, histologic type, invasion of the gastric wall, nodal status and symptoms. Of six variables selected by the univariate analysis, only four (sex, age, lymph node status and degree of invasion in the gastric wall) were validated by the multivariate evaluation, whereas tumor size and symptoms lost their prognostic relevance. The most important variables were nodal status and the degree of invasion in the gastric wall. The influence of age had a different impact on survival time, depending upon nodal status. In fact, patients with positive nodes who were less than 60 years old had the worst prognosis; the same age group with negative nodes had the best prognosis. Multifactorial analysis, according to the automatic interaction detection procedure, showed that prognosis worsened progressively beginning with female patients with negative nodes at pT1 or pT2 (91.6 per cent five year survival rate), male patients with negative nodes at pT1 or pT2 (76.3 per cent five year survival rate), female patients with negative nodes at pT3 or pT4 (62.4 per cent), male patients with negative nodes at pT3 or pT4 (40.0 per cent), patients more than 60 years old with negative nodes (36.8 per cent) and patients less than 60 years old with positive nodes (20.8 per cent). In our opinion, these parameters should be taken into consideration when stratification of patients as candidates to undergo adjuvant treatment after surgical treatment is planned.

All cases of the Regional Cancer Registry, North Baden who developed a gastro-intestinal cancer during the period 1975-1980 were re-examined according to the following parameters: tumor volume, pT stage, pN stage, grading. In the period considered, 8424 cases out of 14,061 cases with histologically proven gastrointestinal cancer could be grouped according to the pT stage. Most of the cases were operated at the pT2 or pT3 stage. Remarkable differences in the different tumor localizations were obtained. Stomach carcinoma had the highest percentage of the pT4 stage (36.2%), rectum carcinoma the lowest (7%). In all primaries a close coherence of tumor volume and pT stage was noted. Carcinoma at the pT1 stage measured 20 cm3 on average, those at the pT4 stage 170 cm3. No coherence of staging and age of the patients could be obtained. Younger patients showed a higher percentage of undifferentiated carcinoma than older patients. Survival data could not be obtained due to the data protection law.

BACKGROUND: Precise knowledge of the abdominal nodal spread of cardia adenocarcinoma in relation to the depth of invasion of the tumor and its longitudinal extension may be very important for the surgeon as a guide in choosing the type of resection and lymphadenectomy.METHODS: The frequency of node metastases in each abdominal station of the first and second tier was prospectively studied in 101 patients with type II and III cardia cancer (defined as approved by the consensus conference held during the second International Gastric Cancer Conference in Munich in April, 1997) who underwent total gastrectomy with D2 lymphadenectomy during the period January 1994 to April 1998. Lymph nodes were retrieved immediately after operation by the surgeon and assigned to the appropriate station according to the classification of the Japanese Research Society for Gastric Cancer.RESULTS: In early gastric cancer, of both type II and type III, lymph node involvement was limited to the perigastric nodes of the upper half of the stomach and to the lymph node station of the celiac trunk. In advanced cancers, whether of type II or type III, there was a fairly high frequency of metastases to the perigastric nodes of the lower half of the stomach; there was also high frequency of metastases at N2 stations, without differences in frequency between pT2 and pT3 tumors (staged according to the classification of the Japanese Research Society for Gastric Cancer).CONCLUSIONS: The results of our study provide evidence for the need to perform a total gastrectomy with D2 lymphadenectomy in all patients with advanced cardia cancer type II or type III. In early cancers, a less extensive resection (proximal gastrectomy) with D2 lymphadenectomy may be indicated.

BACKGROUND: In cases of pT3 gastric cancer, even when standard histological staining reveals no evidence of metastases in the regional lymph nodes, patients still may die of postoperative recurrence of the tumor. An attempt was made in the present study to explain the unfavorable outcome of such patients by investigating the presence of occult cancer cells in lymph nodes by immunostaining of cytokeratin.METHODS: We examined 2310 lymph nodes that had been removed from 83 patients with stage II gastric cancer (pT3, N0, M0). Two consecutive sections of 4 &mgr;m thick were prepared for simultaneous staining with hematoxylin and eosin and immunostaining with the CAM 5.2 monoclonal antibody against cytokeratin, respectively.RESULTS: Evidence of occult involvement was found in 299 of 2310 (13%) lymph nodes and in 54 of 83 (65%) patients with pT3 gastric cancer. An analysis of survival demonstrated the limited 5-year survival of patients with occult involvement in their resected lymph nodes, as compared with that of patients without involvement ( P < 0.01). Moreover, the patients in whom group 2 lymph nodes had occult cancer cells had a significantly poorer prognosis than those in whom occult involvement was limited to group 1 lymph nodes ( P < 0.05).CONCLUSIONS: The accuracy of predictions of prognosis of patients with pT3 gastric cancer should be greatly enhanced if cytokeratin-specific immunostaining is performed in conjunction with routine histopathological examination of lymph nodes.

BACKGROUND: The immunohistochemical expression of thymidylate synthase (TS) and thymidine phosphorylase (TP) was examined in a comparative study of the recurrence rates and prognoses of patients with advanced gastric cancer at the same stage.METHODS: We examined the resected specimens of 67 patients with stage IIIB gastric cancer (pT3, pN2, M0) under 70 years of age who had undergone curative gastrectomy followed by adjuvant chemotherapy with 5-fluoropyrimidines. Paraffin sections of the resected specimens were stained with human anti-TS polyclonal and anti-TP monoclonal antibodies by the avidin-biotin-peroxidase complex (ABC) method.RESULTS: The overall expression of TS and TP was 45.4% and 43.4%, respectively. The postoperative survival curve for the TS-positive group was significantly depressed compared with that for the TS-negative group ( P = 0.0480). The survival curves for TP-positive and TP-negative groups did not show any difference. In regard to the combination of TS and TP expression, the best survival curve was obtained for the TS(-)/TP(+) group, followed by those for the TS(-)/TP(-), TS(+)/TP(-), and TS(+)/TP(+) groups in descending order. With regard to the recurrence site, there was no significant difference in peritoneal recurrence in relation to positivity for TS or TP. Lymph node recurrence, however, was significantly higher in the TS-positive and TP-positive groups, with P-values being 0.0466 and 0.0058, respectively, versus the corresponding negative groups. The incidence of hepatic recurrence was higher in the TP-positive group than in the TP-negative group ( P = 0.0910). As for the total doses of 5-fluoropyrimidines given, more favorable survival curves were obtained for the high dose of negative TS and TP groups, but no significant differences were observed in their positivities.CONCLUSION: The expressions of TS and TP showed different characteristics in overall survival and recurrence rate or site. They should be used for predicting prognosis in comprehension on their properties.

Primary small cell neuroendocrine carcinoma of the upper urinary tract is a rare disease that is associated with a poor prognosis. An 81-year-old man was diagnosed with carcinoma of the stomach and underwent laparoscopic distal gastrectomy. Computed tomography (CT) revealed carcinoma of the left ureter and left hydronephrosis. The patient was diagnosed with carcinoma of the left ureter (cT2N0M0) and left laparoscopic radical nephroureterectomy was performed via a retroperitoneal approach. The pathological diagnosis was left ureter carcinoma (small cell neuroendocrine carcinoma, pT3). He was treated with four courses of the CE regimen (carboplatin area under the curve: 5, intravenously [IV] on day 1 and etoposide [80 mg/m2], IV on days 1-3). There is no evidence of disease at 21 months after radical nephroureterectomy.
