Among the 617 available cases, excluding those in stage 0, the five-year survival rates 95.1 % in stage IA, 91.0% in stage IB, 83.1 % in stage IIA, and 59.0% in stage IIB, respectively. The results showed that cervical tumor greater than 4 cm in diameter, invasion in muscular layers, lower degree of differentiation and pelvic lymph nodes metastasis would lead to worse therapeutic effects. The method of pelvic lymphadenectomy, pathological types, and ages of the patients, however, did not at all correlate with the survival rates of the patients. For those who have risk factors mentioned above active adjutant treatments are indicated.展开更多

Forty-eightpatients with gastrointestinal cancer wererandomized into two groups, one group wasgiven an isocaloric and isonitrogenous standarddiet and the other was fed with the supplementeddiet with glutamine, arginine and ωo-3-fattyacids. Feedings were started within 48 hoursafter operation, and continued until day 8. Allvariables were measured before operation andon postoperative day 1 and 8. Immune responseswere determined by phagocytosis ability,respiratory burst of polymorphonuclear cells,total lymphocytes lymphocyte subsets, nitricoxide, cytokines concentration, andinflammatory responses by plasma levels of C-reactive protein, prostaglandin E2 level.RESULTS Tolerance of both formula diets wasexcellent. There were siagnificant differences inthe immunological and inflammatory responsesbetween the two groups. In supplementedgroup, phagocytosis and respiratory burst aftersurgery was higher and C-reactive protein levelwas lower (P<0.01) than in the standard group.The supplemented group had higher levels ofnitric oxide, total Iymphocytes, T lymphocytes,T-helper cells, and NK cells. Postoperativelevels of IL-6 and TNF-α were lower in thesupplemented group ( P < 0.05).CONCLUSION It was clearly established in thistrial that early postoperative enteral feeding issafe in patients who have undergone majoroperations for gastrointestinal cancer.Supplementation of enteral nutrition withglutamine, arginine, and ω-3 fatty acidspositively modulated postsurgicalimmunosuppressive and inflammatoryresponses.展开更多

In China, HCC ranked second of cancer mortality since 1990s. Hepatitis B and C viruses (HBV and HCV) and dietary aflatoxin intake remain the major causative factors of HCC. Surgery plays a major role in the treatment of HCC, particularly for small HCC. Downstaging unresectable huge HCC to smaller HCC and followed by resection will probably be a new approach for further study. Liver transplantation is indicated for small HCC, however, some issues remain to be solved.Different modes of 'regional cancer therapy for HCC' have been tried. Systemic chemotherapy has been disappointing in the past but the future can be promising.Biotherapy, such as cytokines, differentiation inducers,anti-angiogenic agents, gene therapy and tumor vaccine will probably play a role, particularly in the prevention of tumor recurrence. HCC invasiveness is currently the major target of study. Tremendous works have been done at the molecular level, which will provide clues for biomarker of HCC progressionas well as targets for intervention.展开更多

The prognosis remains dismal due partly to late presentation, with associated low resectability rates, and the aggressive biological nature of these tumors. The median survival time from diagnosis in unresectable tumors remains only 4 6 months.For those patients amenable to surgical resection over the last 20 years have seen marked improvements in postoperative mortality and morbidity, especially in specialist pancreatic centres 23. Despite these changes long-term survival remains low. with a total 5-year survival rate remaining less than 5%.Patients with ampullary cancer have a better 5-year survival of 40°%-60°%.展开更多
