[Comparative study of the fate of a pancreatic stump treated by ligature or by pancreatico-jejunal anastomosis (author's transl)].

The authors studied in a series of 23 dogs divided up into two groups the fate of the pancreatic stump treated either by pancreatico-jejunostomy with a Y loop, or by a simple ligature. They note that although the mortality is slightly higher in the anastomoses, histological lesions are constant in both series and are fairly similar. This agrees with the findings in man by Goldsmith and justifies ligature of the remaining pancreatic stump after cephalic duodeno-pancreatectomy.

[A tumour of the transverse mesocolon (author's transl)].

The authors report a case of mesenchymoma of the transverse mesocolon and analyse 50 cases of tumour of the transverse mesocolon found in the literature. They emphasise the diagnostic difficulties, the pathological characteristics and consider the surgical problems raised by these tumours.

Soft tissue sarcomas in the general population living near a chemical plant in Northern Italy.

BACKGROUND AND OBJECTIVES: After the notification by a general practitioner of a high frequency of soft tissue sarcomas among subjects living close to the industrial area of the city of Mantua (northern Italy), the local Medical Association carried out a formal epidemiologic investigation to corroborate or falsify the hypothesized excess. Several industrial activities of the area were hypothesized to be a source of environmental pollution that might cause soft tissue sarcomas. METHODS: All general practitioners working in the area were requested to report the cases of soft tissue sarcoma diagnosed in the study area. Person-years of observation were computed for all subjects who ever resided in the area between 1984 and 1997. Expected incidence was computed from the cancer registry covering a nearby province (Varese) and from the pool of Italian cancer registries. Peripheral soft tissue sarcoma and visceral sarcomas were included in the analysis. RESULTS AND CONCLUSIONS: Overall, 20 cases were observed in a 13-year period, 8.87 were expected from the Varese province cancer registry and 7.72 from the pool of Italian registries. The corresponding standardized morbidity ratios were 2.25 (95% confidence interval, 1.34-3.47) and 2.6 (95% confidence interval, 1.6-4.0), respectively. A significant excess persisted after excluding 5 cases that had been the object of the original notification. We hypothesize that the soft tissue sarcoma excess may have resulted from environmental pollution by industrial toxic emissions, which likely included 2,3,7,8-tetrachloro-dibenzo-dioxin.

Epirubicin, cisplatin and continuous infusion 5-fluorouracil (ECF) in locally advanced or metastatic gastric cancer: a single institution experience.

AIMS AND BACKGROUND: The role of chemotherapy in locally advanced or metastatic gastric cancer has been controversial, but chemotherapy has recently been shown to relieve tumor-related symptoms, improve quality of life and prolong survival when compared with best supportive care. Furthermore, palliative chemotherapy is also cost-effective. "Second-generation" combination chemotherapy regimens were developed in the 1980s with high activity in advanced or metastatic gastric cancer (EAP, FAMTX, PELF, ECF). In randomized studies, EAP demonstrated no difference in activity but a significantly higher overall toxicity and toxic death rate than FAMTX, and the ECF (epirubicin, cisplatin, 5-fluorouracil) regimen gave a survival and response advantage, tolerable toxicity, better quality of life and was more cost-effective than FAMTX. METHODS: Sixty patients with locally advanced or metastatic gastric cancer were treated with the ECF regimen (21 weeks of 5-fluorouracil given by continuous infusion through a central line at 200 mg/m2 for 24-hr combined with cisplatin at 60 mg/M2 iv and epirubicin at 50 mg/M2 iv beginning on day 1 and repeated every 3 weeks for 8 courses). There were 42 males and 18 females, with a median age of 64 years (range, 40-74). The median performance status was 1. The histologic type was adenocarcinoma in 44 patients and undifferentiated carcinoma in 16 (27%). Three patients had locally advanced disease (5%) and 57 had metastatic disease (95%). Seven patients (12%) had received prior chemotherapy for advanced disease. RESULTS: All patients were assessable for toxicity and 55 for response (5 had insufficient treatment). Toxicity was mild or moderate, and there was no toxic death. Incidence of WHO toxicity > or = 2 was nausea and vomiting in 3%, mucositis in 3%, leukopenia in 7%, anemia in 3%, and thrombocytopenia in 2%. Port-a-Cath toxicity was thrombosis in 4, dislocation in 2 and infection in 3 patients. Seven complete responses and 13 partial responses (overall response rate, 36%) were achieved, with a response rate of 39% in untreated and 17% in pretreated patients. Nine patients (16%) had stable disease and 26 (47%) progressive disease. Most patients felt symptomatically improved on ECF. CONCLUSIONS: Our study confirms that the ECF regimen has a favorable pattern of toxicity and is feasible on an outpatient basis. However, it did not confirm the high response rate reported in other phase II trials.

Carboplatin and etoposide in an out-patient schedule for the palliation of advanced non-small-cell lung cancer.

AIMS AND BACKGROUND: In Western countries, non-small-cell lung cancer is the most important cause of cancer-related death. To date, medical treatment for advanced stages remains of a palliative nature. METHODS: Forty-four patients with advanced non-small-cell lung cancer were treated in a phase II study with carboplatin and etoposide (each at 60 mg/m2 daily) in a 5-day schedule. Among 44 patients, 18 (40%) had stage IIIB disease and 26 (60%) had stage IV disease. RESULTS: Treatment was well tolerated, and the only significant side effect was alopecia. The overall response rate was 27% with 2 complete remissions; median survival time was 10.4 months. One of the 2 patients achieving a complete remission was still alive and disease free at 36 months from the start of therapy. An improvement of performance status was observed in 22 patients (50%). CONCLUSIONS: The combinations of carboplatin and etoposide using this schedule appears to be well tolerated and has some activity in the palliation of advanced non-small-cell lung cancer.

[Surgical treatment of colonic diverticulosis: results of a series of 70 cases].

Results are reported on a series of 70 patients operated upon for colon diverticulosis, surgery being elective in only 23 (32.9%) cases. Global mortality (12.9%), was higher in patients over 70 years of age (P < 0.01) and for emergency cases (17% against 4.3% (NS) after cold surgery). Global morbidity was 20%, the onset of septic complications being influenced (p < 0.01) only by treatment with antiinflammatory drugs. Despite the absence of precise factors predictive of the course of diverticular disease, it should be possible to further improve the very poor prognosis in patients with serious septic complications (Hinchley's stages I to IV) by: prophylactic colectomy in symptomatic diverticulosis, improved evaluation by complementary examinations, notably the scanner, of localized septic complications (stages I and II), with the possible association of guided puncture to avoid the septic areas and to allow performance of a cold colectomy without the need for colostomy. Certain severe septic complications may still develop and these cannot be totally prevented by any therapy. In these cases preference is given to resection of the septic focus using mainly Hartmann's operative techniques. Further studies are needed to evaluate those cases where protected anastomotic resection provides the best results, since in the long term the incidence of re-establishment is higher.
