Sequential treatment with high-dose methotrexate and fluorouracil in advanced colorectal cancer. Experience of the Southern Italian Oncology Group (GOIM).

A total of 101 patients with advanced colorectal cancer in two consecutive Southern Italian Oncology Groups (GOIM) studies (8501 and 8801--arm A) were treated with a sequential combination of high dose methotrexate (HDMTX) and fluorouracil (FU). Of the 92 eligible patients, 2 achieved complete response (2%) and 27 partial response (30%), with a median duration of 7 months. When classified according to the time interval between administration of the two drugs, retrospective analysis showed significant improvement (p = 0.04) in overall survival in the shorter time interval group (6 hours). The observed toxicities were generally mild and transient. Our data confirm the efficacy of the synergism between the two chemotherapeutic agents, in particular when administered with a 6-hour interval. Further studies are necessary to establish the possibility of enhancing the efficacy of sequential treatment with the modulation of FU with high-dose folinic acid.

Influence of the method of digestive tract reconstruction on gallstone development after total gastrectomy for gastric cancer.

The aim of this study was to evaluate whether total gastrectomy performed for gastric cancer leads to an increased risk of cholelithiasis and whether the method of reconstruction of the digestive tract influences that risk. A total of 102 patients who had undergone total gastrectomy for gastric cancer between 1980 and 1990 were studied. The preoperative prevalence of cholelithiasis was 4% in men and 12% in women. Eighty-seven patients (85%) without gallstones before surgery were reexamined after gastrectomy. The postoperative prevalence of cholelithiasis in this group was 36% in men and 19% in women. Before surgery, the difference between the expected frequency of cholelithiasis (calculated on the basis of the data of a community survey) and the observed frequency was not statistically significant (p > 0.05) either in men or women. After surgery, the observed frequency of gallstones was significantly higher than the expected frequency in men (p < 0.0001) but not in women (p = 0.06). The risk of cholelithiasis was significantly higher in patients with Roux-en-Y reconstruction (n = 55) than in those with jejunal interposition (n = 32) (log-rank test, p = 0.03), and that risk was independent of age, sex, and body mass index.

[J-pouch after total gastrectomy].

The Authors report their initial experience with the construction of a J-pouch as restorative surgery following total gastrectomy (TG) for malignant neoplasms. In the last 10 months of the 1990 upon 52 interventions for gastric cancer 31 TG were performed, and in 13 cases a J-pouch on the proximal end of the jejunal segment was constructed. No mortality or specific morbidity was registered using the totally stapled technique. Within one month 3/4 of the patients had normal meals as far as quantity and quality; also the foamy regurgitation seemed to be minimal. The ease of the reconstructive technique and the short term results obtained encourage the use of such approach.

[A new reconstructive model after total proctectomy].

The Authors describe a new reconstructive model after total proctectomy: the S-E colo-anal anastomosis (S-E CAA). The technical requisites of this variant are discussed and compared with more traditional reconstruction models. At a first evaluation of the results, the S-E CAA seems to be able to sensibly ameliorate the course and the outcome of the anastomosis and to hasten the recovery of the normal sphincteric function.
