Influence of Prognostic Factors for Recurrence of Adenocarcinoma of the Stomach

Introduction:

Gastric cancer is the second most important neoplasm in the world. Surgical resection is the treatment of choice for gastric cancer, and recognized by the International Union against Cancer (International Union Against Cancer – UICC) TNM classification of the parameters of the tumor and lymph node. Prognostic factors related to characteristics of the tumor by histopathologic findings have an impact on the planning of the operation. According to the results of most studies it is possible to predict survival and recurrence based on histological type and TNM classification of tumors on the one hand and the surgical procedure on the other.

Aim:

The aim of the research was to analyze prognostic factors that influenced the frequency of recurrence in gastric surgery patients.

Patients and methods:

The five year study covered a population of 100 treated patients of adenocarcinoma of the stomach at the Department of Surgery, University Clinical Center Tuzla. The first group were characteristics of tumors in patients with gastric adenocarcinoma. Lymphadenectomy and splenectomy, types of surgery were the second group of prognostic factors.

Results:

Histological type and TNM stage of tumor as prognostic factors had a significant impact on local tumor recurrence. The type of surgery had no statistically significant value for tumor recurrence (p = 0.7520).

Conclusion:

Statistical analysis of prognostic factors related to histopathologic characteristics of tumors and the type of surgery gave the results that had an impact on recurrence in gastric surgery patients. The most important prognostic factors were TNM stage of tumor and histological type of tumor that influenced the incidence of recurrence.

Opiate Analgesia Treatment Reduced Early Inflammatory Response After Severe Chest Injuries

Background:

The frequency of severe chest injuries are increased. Their high morbidity is followed by systemic inflammatory response. The efficacy of pharmacological blockade of the response could prevent complications after chest injures.

Aim:

The aim of the study was to show an inflammatory response level, its prognostic significant and length of hospital stay after chest injures opiate analgesia treatment.

Methods:

Sixty patients from Department of Thoracic Surgery with severe chest injures were included in the prospective study. With respect of non opiate or opiate analgesia treatment, the patients were divided in two groups consisted of 30 patients. As a inflammatory markers, serum values of leukocytes, neutrophils, C-reactive protein (CRP) and fibrinogen in three measurements: at the time of admission, 24hours and 48 hours after admission, were followed.

Results:

Statistically significant differences were found between the examined groups in mean serum values of neutrophils (p=0.026 and p=0.03) in the second and the third measurement, CRP (p=0.05 and 0.25) in the second and the third measurement and leukocytes in the third measurement (p=0.016). 6 patients in group I and 3 in group II had initial stage of pneumonia, 13 patients in group I and 6 in group II had atelectasis and 7 patients from group I and 4 from group II had pleural effusion. The rate of complications was lower in group of patient who were under opiate analgesia treatment but without significant difference. The length of hospital stay for the patients in group I was 7.3±1.15 days and for the patients in group II it was 6.1±0.87 days with statistically significant difference p=0.017.

Conclusion:

The opiate analgesia in patients with severe chest injures reduced level of early inflammatory response, rate of intra hospital complications and length of hospital stay.

Surgical treatment and complications of treating pancreatic tumor

Pancreatic tumor is one with the worst prognosis of all cancers, and the tenth most frequent cancer in Europe, making the 3% of all cancers affecting both sexes. Most patients seek treatment when the disease is in its advanced stage and the level for possible resectability is low. Late presentation of the disease is responsible for the short survival period of 6 months and a five-year survival of 0.4 to 5% of patients. At the Clinic for Surgery in Tuzla during period from January 1st 1996, to January 1st 2011, a total of 127 resection surgeries were performed due to malignant tumors. The goal of this study was to show that adequate assessment of operability, proper surgical strategy and modern techniques of creating anastomoses reduces morbidity and mortality, results in fewer postoperative complications and contributes to better surgical results. In our study sample the most common place of tumor location was the head of pancreas, in 69 (59.7%) patients. Men develop this type of cancer more often than women in the ratio of 2:1, while the median age of patients was 62 years. We faced postoperative complications in 37 (29.1%) patients, pancreatic fistula being the most prevalent complication, occurring in 16 (12.6%) patients. Overall early and late postoperative mortality was observed in 12 (9.8%) patients.

CONCLUSION

Patients with chronic and hereditary pancreatitis are at a higher risk for developing pancreatic cancer and should be screened for the purpose of early diagnosis. The staging of pancreatic cancer has improved, with the accuracy of 85-90%. Postoperative complications, morbidity, and mortality are significantly reduced (p < 0.05) if the standardized operational procedure is applied and if modern techniques are used to create pancreaticojejunal anastomosis as the anastomosis carrying the highest risk.
