Ovarian carcinoma is the fifth most common cause of death among women in western countries. It is often diagnosed in an advanced stage (FIGO Stage III and IV) and requires effective chemotherapy as first-line treatment. The advent of cis-platin combined with adriamycin and cyclophosphamide has remarkably increased the response rate in advanced disease. The authors report 31 cases of epithelial ovarian neoplasia, without prior chemotherapy, treated with cis-platin, adriamycin and cyclophosphamide (PAC I). Of the 30 evaluable patients, 15 had clinical complete remissions (cCR = 50%), 10 clinical partial remissions (cPR = 33%) and 5 no response (NR = 17%). The total response (cCR + cPR) was equal to 83%. Twelve of the 15 patients in cCR underwent second-look laparotomy; in 8 of these cases, histologic and cytologic confirmation of CR was obtained. PAC I was found to be a highly effective therapeutic regimen with moderate toxicity. The individual toxicity reported was gastroenteric (nausea and vomiting), but transitory. No chronic toxic side-effects from cisplatin or adriamycin were noted. However, more definitive results must be obtained to verify its impact on the prolongation of survival.

The identification of susceptibility genes for specific types of cancer provided the necessary information for the complete characterization of inherited cancer syndromes. The close observation of carrier families has significantly enriched our knowledge on distinct phenotypical features, age of onset and survival rates for each syndrome and gave the opportunity to further understand the molecular basis of hereditary cancer. Recent advances in cancer genetics involve the identification of novel genes with moderate risk to cause cancer, after synergism with particular environmental factors, and therefore reinforcing the genetic component in relation to cancer predisposition. The available genetic tests can constitute an essential step of primary health care, as they can dramatically affect the quality of a cancer patient's life and they can also offer prompt diagnosis for the patient's close relatives. This review reports the most characteristic hereditary cancer syndromes along with their phenotypical and genetic variables that have been described, but it mainly focuses on Hereditary Non-Polyposis Colorectal Cancer (HNPCC), which is linked to pathogenic mutations in one of the mismatch repair (MMR) genes MLH1, MSH2, MSH6, Familial Adenomatous Polyposis (FAP) caused by high-penetrant mutations within the APC gene and Hereditary Breast/Ovarian Cancer (HBOC) linked to mutations within BRCA1 and BRCA2 genes.
