[Current status of the classification and clinical staging of primary and secondary tumors of the liver].

Over the past few decades there has been outstanding expansion in the surgical exeresis of primary and metastatic liver tumours and particularly hepatic metastases of colorectal carcinomas. With the advance in surgical technique it becomes increasingly necessary to codify the system for the classification and clinical staging of these conditions for the purposes of correct programming of treatment and assessment of the clinical results obtained. The most commonly used systems of classification and clinical staging are analysed, in particular the classifications proposed by the American Joint Committee on Cancer and D. Manfredi for primary liver tumours and those proposed by Gennari et al and Sugerbaker et al for hepatic metastases of colorectal carcinomas. The selection criteria adopted in each system are analysed as the basis for a more thorough discussion of the problem that is felt to be fundamental for the standardisation of classification and clinical staging systems in the future. Such standardisation is essential for the assessment of the value and limitations of liver surgery in cancer.

[Role of surgery in the prognosis of AIDS and related syndromes. Case reports ].

The authors review the epidemiologic and etiopathogenetic aspects of AIDS, in agreement with data published in december by the Center for Disease Control and by the WHO for the States, Europe and Italy. In their experience twenty-one patients, with clinical clues of AIDS, undergoing lymph node biopsy, have been analysed (18 LAS-ARC and 3 AIDS) and the role of prophylaxis for the surgical approach to the patient with aids or related syndrome has been underlined.

Sentinel lymph node mapping and biopsy for breast cancer: a review of the literature relative to 4791 procedures.

The status of axillary nodes is the most important prognostic factor in breast cancer to select patient subgroups for adjuvant chemotherapy; the current standard of care for surgical management of invasive breast cancer is complete removal of the tumor by either mastectomy or lumpectomy followed by axillary lymph node dissection (ALND). The recent introduction of intraoperative lymphatic mapping and sentinel lymph node biopsy (SLND) represents a major new opportunity for appropriate and less invasive surgical management of many tumors. There is an almost uniformly enthusiasm concerning the potential of this technique in breast carcinoma management, shown by published data. A peculiar attention to the so-called "sentinel node debate" in breast cancer surgery is a constant in the last years issues of the major medical journals. Even patients have become more aware about medical enthusiasm and their request of concise information on the topic and the possibilities of this approach is an increasing reality in medical practice. The aim of this paper is to review recent literature to offer an overview about the main controversial methodological aspects and a wide analysis of reported results. The most significative international literature papers from Medline were retrieved from 1993 to September 1999, and 4782 procedures were analysed. This extensive review of the literature has confirmed accuracy, feasibility and reliability of the SN detecting technique in axillary mapping. Provided a good proficiency in SN localisation and pathological evaluation, human resources and efforts should be mainly focused on its clinical validation as an alternative to ALND instead of on further phase I-lI clinical studies.

Intrahepatic epidoxorubicin in metastatic and primary liver tumours: a phase II study.

Primary and metastatic gastrointestinal tumours in the liver have been treated by intrahepatic artery infusion of chemotherapeutic drugs in an attempt to increase the efficacy of the administered agents. Among the several active agents, 4' epidoxorubicin, an anthracycline analogue, was selected for this study because of the therapeutic level reached in the liver by this drug. Seven patients with primary hepatic carcinoma and twenty with metastatic adenocarcinoma of the colon to the liver received intraarterial hepatic infusion of epidoxorubicin at the dosage of 30 mg weekly. No haematological or gastrointestinal grade 3-4 toxicity was recorded, only one patient experienced transient cardiac toxicity. No objective response was observed in primary hepatic carcinoma and six objective responses, 1 complete and 5 partial (30%), were achieved in metastatic colorectal cancer patients. This results is not far from those reported with FUDR, but does not justify epidoxorubicin in colorectal cancer patients as first line intraarterial treatment.

Gastric cancer: a review of 400 consecutive cases.

Four hundred out of 422 patients with primary gastric cancer seen from 1965 to 1979 underwent surgical treatment and were studied retrospectively. Fifty-eight percent underwent curative procedures. The five year survival rate was 19.14%. Subtotal and total gastrectomy gave survival rates of 35.8% and 9% respectively (p less than 0.05). Postoperative mortality (24.2%) was influenced by both the type of procedure performed (p less than 0.001) and the stage of the neoplasis (p less than 0.001). This study confirms the influence of staging on short, intermediate and long term survival and demonstrates the importance of the early diagnosis of gastric cancer in carrying out effective surgical treatment.

Pseudomixoma peritonei: a case report.

Pseudomixoma peritonei is a rare neoplasm characterized by mucinous ascites and the mucinous involvement of peritoneal surfaces, omentum and bowel loops. Usually pseudomixoma peritonei is associated with benign or malignant mucinous tumor of the appendix or ovary. The diagnosis of pseudomixoma peritonei is difficult because laboratory and radiology results are frequently nondiagnostic. We report a case that was initially mistaken for carcinomatosis of unknown origin and that underwent cytoreductive procedure and omentectomy as the treatment of choice.
