Guidelines for the management of biliary tract and ampullary carcinomas: surgical treatment

The only curative treatment in biliary tract cancer is surgical treatment. Therefore, the suitability of curative resection should be investigated in the first place. In the presence of metastasis to the liver, lung, peritoneum, or distant lymph nodes, curative resection is not suitable. No definite consensus has been reached on local extension factors and curability. Measures of hepatic functional reserve in the jaundiced liver include future liver remnant volume and the indocyanine green (ICG) clearance test. Preoperative portal vein embolization may be considered in patients in whom right hepatectomy or more, or hepatectomy with a resection rate exceeding 50%–60% is planned. Postoperative complications and surgery-related mortality may be reduced with the use of portal vein embolization. Although hepatectomy and/or pancreaticoduodenectomy are preferable for the curative resection of bile duct cancer, extrahepatic bile duct resection alone is also considered in patients for whom it is judged that curative resection would be achieved after a strict diagnosis of its local extension. Also, combined caudate lobe resection is recommended for hilar cholangiocarcinoma. Because the prognosis of patients treated with combined portal vein resection is significantly better than that of unresected patients, combined portal vein resection may be carried out. Prognostic factors after resection for bile duct cancer include positive surgical margins, especially in the ductal stump; lymph node metastasis; perineural invasion; and combined vascular resection due to portal vein and/or hepatic artery invasion. For patients with suspected gallbladder cancer, laparoscopic cholecystectomy is not recommended, and open cholecystectomy should be performed as a rule. When gallbladder cancer invading the subserosal layer or deeper has been detected after simple cholecystectomy, additional resection should be considered. Prognostic factors after resection for gallbladder cancer include the depth of mural invasion; lymph node metastasis; extramural extension, especially into the hepatoduodenal ligament; perineural invasion; and the degree of curability. Pancreaticoduodenectomy is indicated for ampullary carcinoma, and limited operation is also indicated for carcinoma in adenoma. The prognostic factors after resection for ampullary carcinoma include lymph node metastasis, pancreatic invasion, and perineural invasion.     

The spread and prognosis of carcinoma in the region of the pancreatic head

Tumor infiltration and prognosis were studied in 73 patients who underwent surgery for carcinoma in the region of the pancreatic head, in order to evaluate the grade of malignancy of pancreatic cancer. Twenty three patients had carcinoma of the head of the pancreas, 16 had carcinoma of the intrapancreatic bile duct and 34 had carcinoma of the papilla of Vater. It was found that the prognosis in carcinoma of the head of the pancreas was not related to tumor size, but to lymph node metastasis and the pancreatic capsular or perineural invasion of the tumor. The poorer prognosis seen in carcinoma of the head of the pancreas could be attributed to the fact that lymph node metastasis and invasion of the pancreatic capsule or nerve plexus occurred much more frequently in this carcinoma than in carcinoma of the other two areas. The 5-year survival rate of the patients with carcinoma of the head of the pancreas was 12.5 per cent, this being significantly lower than that of the patients with either carcinoma of the papilla of Vater (50.0 per cent) or carcinoma of the intrapancreatic bile duct (44.4 per cent). These findings suggest that lymph node metastasis and pancreatic capsular or perineural invasion closely correlate with the prognosis of patients with pancreatic carcinoma.

Predictors for Patterns of Failure after Pancreaticoduodenectomy in Ampullary Cancer

Background Ampullary cancer has the best prognosis in periampullary malignancy but unpredicted early recurrence after resection is frequent. The current study tried to find the predictors for recurrence to be used as determinative for postoperative adjuvant therapy. Methods Information was collected from patients who underwent pancreaticoduodenectomy with regional lymphadenectomy for ampullary cancer in high-volume hospitals between January 1989 and April 2005. Recurrence patterns and survival rates were calculated and predictors were identified. Results A total of 135 eligible patients were included. The 30-day operative mortality was 3%. Median followup for relapse-free patients was 52 months. Disease recurred in 57 (42%) patients, including 31 liver metastases, 26 locoregional recurrences, 9 peritoneal carcinomatoses, 7 bone metastases, and 6 other sites. Pancreatic invasion (P = 0.04) and tumor size (P = 0.05) were the predictors for locoregional recurrence, while lymph node metastasis was the sole predictor for liver metastasis (P = 0.01). The 5-year disease-specific survival rate was 45.7%; 77.7% for stage I, 28.5% for stage II, and 16.5% for stage III; and 63.7% for node-negative versus 19.1% for node-positive patients. Pancreatic invasion and lymph node involvement were both predictors for survival of patients with ampullary cancer. Conclusion Pancreaticoduodenectomy with regional lymphadenectomy is adequate for early-stage ampullary cancer but a dismal outcome can be predicted in patients with lymph node metastasis and pancreatic invasion. Lymph node metastasis and pancreatic invasion can be used to guide individualized, risk-oriented adjuvant therapy.     

Long-term survival after radical resection for pancreatic head and ampullary cancer: a potential role for the EGF-R

BACKGROUND/AIM: Pancreatic cancer has a dismal prognosis. Ampullary cancer (defined as cancer of the ampulla of Vater or the distal common bile duct) has a better prognosis and is thought to be a biologically different tumor. The aim of this study was to find factors that could predict survival after radical (R-0) resection for pancreatic head and ampullary cancers. METHODS: We analyzed clinical and pathological data from 93 patients who underwent a true R-0 resection for pancreatic head or ampullary cancer. Furthermore, we performed a tissue microarray protein expression analysis for several growth factor receptors and oncogenes: HER-2, EGF-R, ER, PR, C-myc, p53, p16, RB-1, and chromogranin A as a neuroendocrine differentiation marker. RESULTS: Median survival (14 vs. 42 months) and time to recurrence (16 vs. 42 months) were significantly longer for ampullary than for pancreatic head cancers. Preoperative pain, perineural invasion, lymph node metastasis, and tumor differentiation grade are indicators of a poor survival. No differences in protein expression were found between groups, except for EGF-R which was expressed more in pancreatic head cancers (p = 0.026). CONCLUSIONS: Outcomes for ampullary cancers are better than for pancreatic head cancers. This different biological behavior can possibly be explained by differences in EGF-R expression.

Abstract：

Objective To study the expression of mosaic lymphatic (ML) in human rectal carcinoma and its clinical significance. Methods Forty-eight specimens of rectal carcinoma were stained by immunohistochemical method. The patterns of mosaic lymphatic in rectal carcinoma were observed, and their correlation with invasion, lymph node metastasis and distant metastasis of rectal carcinoma was analyzed. Results ML was found in 17 of the 46 specimens, and there was no significant correlation between ML and invasion depth of rectal carcinoma. But ML was associated with existence of lymph node metastasis (r =0. 474,P ＜0. 01 ) and distant metastasis (r =0. 417 ,P ＜0. 01 ) positively. Conclusion There was a positive correlation between the expression of LM with invasion depth, lymph node metastasis and distant metastasis.     

Prognostic Factors for Sporadic Medullary Thyroid Carcinoma

Introduction Medullary thyroid carcinoma (MTC) originates from the thyroid parafollicular cells and accounts for 3% to 10% of all thyroid malignancies. Approximately 84% of cases are sporadic. The aim of this study was to evaluate the outcomes of treatment for sporadic medullary thyroid carcinoma (SMTC) and define the prognostic factors for overall survival. Methods The records of 32 SMTC patients treated at Ankara Oncology Education and Research Hospital between September 1993 and April 2003 were retrospectively evaluated. The effects of age, gender, tumor localization, extent of the primary surgical resection, tumor size, capsule invasion, lymph node metastasis, extranodal extension, tumor stage, local recurrence, and distant metastasis on the overall survival rate were evaluated by univariate and multivariate analyses. Results There were 32 patients (19 females, 13 males) with a median age of 45 years (21–76 years). Altogether, 22 patients had undergone complete resection and 10 patients incomplete resection. The median follow-up was 48 months (9–111 months), and the overall 5-year survival rate was 51%. Based on the univariate analysis, the extent of primary surgical resection, pathologic tumor size, capsule invasion, lymph node invasion, extranodal extension, tumor stage, local recurrence, and distant metastasis were factors that significantly affected survival. In the multivariate analysis, however, only the extent of the primary surgical resection, capsule invasion, and distant metastasis were found to be statistically significant factors. Conclusions The extent of the primary surgical resection significantly influences the survival of patients with SMTC. Capsule invasion and distant metastasis were additional factors affecting the prognosis.
