Abstract

Background

Peripheral cholangiocarcinoma (PCC) constitutes the second most common primary liver cancer. Information is lacking on patients with PCC <40 years old undergoing surgical treatment. The aim of this study was to evaluate the influence of age on surgical treatment of patients with PCC based on reviewing the clinicopathologic features and survival rate of 23 patients with PCC <40 years old who received surgical treatment.

Methods

The clinical features of 23 younger patients with PCC (<40 years old) who underwent surgical treatment between 1977 and 2000 were reviewed. Clinical features of 284 patients with PCC >40 years old were used for comparison.

Results

Three hundred seven patients with PCC with an age range between 28 and 93 years (mean 57.2, median 56.0) were investigated. The fiftieth decade was the peak PCC age in the series. Clinical presentations and physical findings were similar between younger and older PCC groups. Similar positive serum carcinoembryonic antigen and carbohydrate antigen 19-9 rates (42.9% and 66.7% vs 41.2% and 74.4%, respectively) and a similar rate of hepatolithiasis associated with PCC were also observed between the 2 groups (43.5% vs 48.9%). Younger patients with PCC tended to show less mucobilia, less papillary-type PCC, and a more advanced stage of tumor compared with older patients with PCC. However, postoperative adjuvant chemotherapy and radiotherapy were used more frequently in the older patients with PCC. Operative morbidity and mortality were similar between the 2 groups (surgical mortality rate 7.8%). Follow-up ranged from 1.0 to 167.6 months (mean 13.0, median 5.7). The 1- and 2-year actuarial survival rates were 6.3% and 0% in the younger PCC group and 31.3% and 15.0% in the older PCC group, respectively. Prognosis was dismal for the younger patients with PCC (P = 0.0008), but they may benefit from hepatic resection.

Conclusions

Younger patients with PCC had a significantly worse survival rate than older patients with PCC. Hepatectomy is rational and may benefit younger patients with PCC.

Methods

From 1977 to 2000, 518 consecutive patients with bile duct adenocarcinoma underwent surgical treatment at the Department of Surgery, Chang-Gung Memorial Hospital, Taipei, Taiwan. The 518 patients were classified into common bile duct cancer (n = 89, 17.2%), PCC with hilar invasion (n = 122, 23.6%), and PCC (n = 307, 59.3%). Three hundred seven patients with PCC were enrolled in this investigation. PCC was defined as carcinoma arising from second order or more distal branches of the intrahepatic

Results

Three hundred seven PCC patients with ages ranging between 28 and 93 years (mean 57.2, median 56.0) were studied. The fiftieth decade was the peak PCC age in the series, and 23 patients with PCC were <40 years old (7.49%; Fig. 1). There were 9 men and 14 women (male-to-female ratio 0.64) in the younger PCC group and 121 men and 163 women (male-to-female ratio 0.74) in the older PCC group. The gender ratio was similar between the 2 groups (P = 0.746).

Right hypochondralgia was the most common

Comments

The average patient age at clinical diagnosis of PCC in Japan and the United States is 60 to 65 years; the hilar type is normally detected somewhat earlier than the peripheral type. In the United Kingdom, average patient age at clinical diagnosis of PCC is 48 ± 11 years for the peripheral type and 52 ± 12.5 years for the hilar type [9]. This study showed that Taiwanese PCC age distribution peaked for patients >50 years of age. PCC commonly affects older people, and only 7.7% of patients with

      Among other factors, age was found to be an independent risk factor for postoperative mortality after MH for PHC.28,29 Contradictory to these results, 2 further studies found that surgery for PHC can be safely performed in elderly patients.30,31 However, it has been shown that the comparison of mortality rates between Eastern and Western centers is difficult, at least in part, owing to significant differences in patient characteristics.32

      Survival is related to the pathological grading of the tumour: better survival observed in well-differentiated cancers (mean survival 10 months, anaplastic tumours 2 months). A 2004 publication describes a worse survival-rate in younger patients (<40 years) after curative resection in case of peripheral carcinoma of the biliary tract (Yeh et al., 2004). Diagnosis of CCA can be a challenge because of its anatomic location and late clinical presentation.

      Predictors of poor survival in the present series were transfusion requirements and perineural invasion. Independent predictors of survival in other published studies were age <40 years, lymphatic invasion, and preoperative CA 19-9 levels of >37 ng/dL.3,10-12 Interestingly, the current series did not demonstrate an association between positive margins and poor survival.

The clinical signs and symptoms depend on the location of the tumour.
