Prognostic significance of DNA ploidy, S-phase fraction, and tissue levels of aspartic, cysteine, and serine proteases in operable gastric carcinoma.

A consecutive series of 63 untreated patients undergoing surgical resection for stage I-IV gastric adenocarcinomas (GCs) has been prospectively studied. Our purpose was to analyze the predictive relevance of DNA ploidy, S-phase fraction (SPF), and tissue levels of lysosomal proteinases cathepsin D (CD), cathepsin B (CB), cathepsin L (CL), and urokinase-type plasminogen activator (uPA) and that of the intracellular cysteine proteinase inhibitor stefin A on clinical outcome. All of the patients taking part in this study were followed up for a median of 73 months. DNA aneuploidy was present in 71% of the cases (45/63), whereas 9% of these (4/45) showed multiclonality. Both DNA ploidy and SPF were associated with tumor-node-metastasis (TNM) stage and node status, whereas only DNA ploidy was related to depth of invasion. CB, CL, uPA, but not CD, levels were significantly higher in GC as compared to paired normal mucosa, whereas stefin A levels were lower in tumor tissues. CB levels were significantly associated with TNM stage, nodal status, histological grade, and DNA ploidy. At univariate analysis, only node involvement, advanced TNM stage, DNA aneuploidy, and high SPF proved to be significantly related to quicker relapse and to shorter overall survival, whereas depth of invasion was related only to survival. With multivariate analysis, only high SPF (>15.2%) was related to risk of relapse (RR = 8.50), whereas high SPF and DNA aneuploidy were independently related to risk of death (RR = 1.88 and 2.09, respectively). Our preliminary prospective study has identified SPF and DNA ploidy as important biological indicators for predicting the outcome of patients with GC.

[Intra-arterial chemotherapy in the treatment of liver metastases of colorectal cancer].

AIM: The authors evaluate the value of hepatic intrarterial chemotherapy (HAC) as an alternative treatment for hepatic metastases from colo-rectum cancer unsuited to radical surgery. METHODS: This study evaluates the physiopathological and pharmacodynamic bases for this type of treatment, the correct procedure for patient staging and selection, the surgical technique used to insert the infusional system, surgical complications and those linked to endoarterial treatment, the evaluation of response and the results. Complications correlated to the infusional system were evaluated in a total of 1223 patients in 10 non-randomised studies and 7 randomised studies taken from the literature. Complications correlated to chemotherapy were analysed in a total of 777 patients from 8 randomised studies and 7 randomised using FUDR. Special emphasis was placed on the possible association of locoregional and systemic treatment in order to prevent extrahepatic progression, the main cause of death in patients undergoing a single cycle of HAC. RESULTS: By comparing locoregional and systemic treatment taken from a number of randomised and non-randomised studies, the results were evaluated in terms of objective response and survival. CONCLUSIONS: There was no proportional increase in survival rates compared to systemic treatment only, in spite of the large proportion of objective responses achieved using locoregional treatment alone.

Flow cytometric DNA analysis of hepatic tumours on ultrasound-guided fine-needle aspirates.

A study was performed on a nonconsecutive series of 51 patients in order to assess the feasibility, reliability, and usefulness of flow cytometric (FCM) DNA analysis of samples obtained from benign and malignant hepatic tumours by means of ultrasound-guided fine-needle aspiration (UG-FNA). Cytological and often histological confirmation of the nature of the lesion was obtained in all cases from an expert pathologist. For FCM DNA analysis in 32 cases, it was also possible to use samples obtained at surgery from the actual tumours. There were no post UG-FNA complications, either early or late. It was possible to perform FCM DNA analysis on 6/7 (85.7%) of the benign tumour aspirates and all 44 (100%) coming from the malignant tumours. All the benign tumours showed a DNA-diploid pattern, while the DNA content was aneuploid in 91% of the malignant tumours. Apart from one case, the results of the FCM DNA analysis of the samples removed at surgery were the same as those obtained from the aspirates (97%). FCM DNA analysis on UG-FNA samples from hepatic tumours is a fairly simple, reproducible, well-tolerated technique; it does not involve risks if performed by skilled operators and, since it can be easily repeated even on small tumours, it is a suitable method for monitoring hepatic metastases during chemotherapy.

Advantages and disadvantages of mechanical vs. manual anastomosis in colorectal surgery. A prospective study.

The merits of mechanical versus manual anastomosis were evaluated in a prospective study of 48 patients undergoing resection of colonic or rectal cancer. The analyzed factors included the time required for construction of the anastomosis, the length of hospital stay, the cost/benefit ratio and complications. The anastomosis was manually performed with monolayer polyglactin 910 sutures in 24 cases and mechanically with an E.E.A. stapler in 24. The anastomosis time averaged 14 min in the suture group and 14.3 min in the stapling group, and the respective hospitalization times were 16 and 17 days. The mean cost was 48,000 lire in the manual, and 200,000 lire in the mechanical group. Four complications occurred in each group. Apart from the cost, no intergroup difference was statistically significant.

[Screening for liver metastases of colorectal carcinoma by the routine use of intraoperative echography].

The detection and distribution of liver metastases from colorectal carcinoma is an important problem for the therapeutic approach and prognosis. In this study we evaluated the diagnostic accuracy and technical utility of intraoperative ultrasonography (I.O.U.) in the treatment for liver metastases from colorectal carcinoma. I.O.U. has been routine performed in 70 patients. 13 metastatic lesions have been diagnosed in 10/70 patients with colorectal carcinoma (14.3%). Only 6 of 13 lesions (sensitivity of 46.1%) have been diagnosed preoperatively and/or by surgical exploration. Instead 7 small intrahepatic metastatic lesions (53.9%) have been diagnosed exclusively by I.O.U. It has not been possible to detect this lesions by surgical exploration; the size of these metastatic tumor ranged from 0.4 x 0.6 to 1.2 x 1.6 cm. I.O.U. has been useful for its high sensitivity, for the study of anatomic relation between metastatic lesions and vascular and biliary hepatic structure (good guidance for surgical hepatic resection) and for the possibility of performing deep ultrasound guided biopsies of hepatic lesions.

Role of intraoperative ultrasound in the screening of liver metastases from colorectal carcinoma: initial experiences.

The aim of this study was to assess the utility of intraoperative ultrasound (IOUS) in the diagnosis and management of liver metastases from colorectal carcinoma. IOUS was performed on a consecutive series of 70 patients undergoing surgery for colorectal carcinoma, with follow-up ranging from 6 to 24 months. In ten cases (14.3%), 13 metastatic tumours were diagnosed; only six of these had been found by preoperative workup and/or surgical inspection. Seven (53.9%) small metastatic liver lesions were identified only by IOUS. None of the lesions diagnosed by IOUS was palpable, and they were all extremely small--ranging from 4 x 6 to 12 x 16 mm. Seventy-three locations were examined in order to compare the results of IOUS with those of other methods. The sensitivity of the former proved to be higher (P less than .05) than that of conventional pre- and intraoperative screening.
