Summary:
Introduction: The Czech Republic has the world’s highest rates of pancreatic carcinomas. The pancreatic carcinoma is the fourth commonest
cause of deaths due to malignancies, in our republic. Resection procedure is currently the only current treatment method, which
has a curative potential and significantly prolongs a patient’s life.
Aim: To assess morbidity, mortality and survival of patients following radical and paliative procedures in the pancreatic head carcinoma
patients.
Methods and Patient Group: Only patients, who, based on the preoperative staging, were expected to require the following procedures,
were indicated for surgery: 1 – radical resection, i.e. stage I, II patients, 2 – palliative resection – i.e. stage III or IV patients, where
no angioinvasion was detected preoperatively. Patients with peroperative detection of angioinvasion into the portomesenteric venous drainage
area who required partial vein resection , were also included in the above subgroup. 3 – palliative bypass, where longer survival
was expected.
Radical resection included proximal pancreatoduodenectomy (PDE) with preservation of the pylorus according to Traverso-Longmire,
with N1-2 lymphadenectomy and with reconstruction to an excluded jejunal loop. The same procedure was followed in cases of palliative
resections. The collected data were statistically assessed using the Logrank test.
From 05/1998 to 12/2006, a total of 307 patients with carcinomas of the pancreas and the Vater papila were treated. In 242 patients,
the carcinoma was located within the pancreatic head, in 65 subjects, the pancreatic body and cauda were affected. Resection for the pancreatic
head carcinoma was performed in 78 patients: 46 males, 32 females, the mean age was 63.5 y.o.a, with the median of 64 years.
Bypass procedures were performed in 109 subjects and explorations in 55 subjects.
Results: Surgical procedures, with exception of 55 subjects who underwent exploration only, were performed in 187 subjects. Out of
the total 78 PDEs, resections in stage I and II were performed in 22 subjects, in stage III in 41 subjects. In the group of 63 radical resection
subjects, 2 subjects exited: the first one due to multiorgan failure, the second one for necrotizing postoperative pancreatitis. In the
group of 15 palliative resections, 3 subjects exited. 10 patients died during the early postoperative period after palliative bypass procedures.
A total of 15 subjects, i.e. 8%, exited during the early postoperative period. 5 subjects exited after resection procedures, i.e. 6.4%, 3%
after radical resections. 3 subjects exited after palliative resections. Early complications were recorded in 44 subjects: pancreato-jejuno
anastomosis insufficiency in 6 patients, insufficiency of hepaticojejunoanastomosis in 5 subjects, postoperative pancreatitis in 5 subjects,
intraabdominal absces in 10 subjects, wounds infections with secondary healing in 19 subjects and cardiopulmonary complications in 33
subjects. In 19 subjects (43 % of all complications), surgical revision was performed.
Three-year survival rates were recorded in 60, resp. 29.5 and 39.5 % of the patients in stage I, resp. II and III, while they were recorded
in 15.6.% of the stage IVa subjects and only in 10.5% of the stage IVb subjects. There is a significant difference between survival
rates of the stage I, II and III patients, compared to the stage IV patients (p < 0.005). There is no significant difference in the over- 3-
years survival rates between the patients undergoing radical or palliative resections, however, the radical resection patients have significantly
higher survival rates 3 months to 2 years postoperatively (p < 0.05).The radical resection subjects have significantly higher survival
rates during the first 36 postoperative months, compared to the palliative resection and BDA subjects (p < 0.05). Comparison of survival
rates in patients with radical or palliative resections is affected by a small number of the palliative resection subjects (n = 15), where
no differences in survival rates were detected from the end of 9th postoperative month to the end of 3rd postoperative year. There is a significant
difference in the survival rates between the resection and exploration subjects (p < 0.05). The survival rates differences between
the subjects with palliative resections and BDAs cannot be evaluated in our study, due to nonhomogenity of the subjects.
Conclusion: Radical PDEs for the pancreatic head carcinoma results in significantly longer survival of the subjects, compared to palliative
bypasses. Stage I, II or III patients survive significantly longer, compared to those operated in stage IV.
Key words:
pancreatic carcinoma – radical resection – palliative treatment – complications – survival
