Purpose To identify factors associated with outcome after surgical management of intrahepatic cholangiocarcinoma (ICC) and examine the impact of lymph node (LN) assessment on survival. Patients and Methods From an international multi-institutional database, 449 patients who underwent surgery for ICC between 1973 and 2010 were identified. Clinical and pathologic data were evaluated using uni- and multivariate analyses. Results Median tumor size was 6.5 cm. Most patients had a solitary tumor (73%) and no vascular invasion (69%). Median survival was 27 months, and 5-year survival was 31%. Factors associated with adverse prognosis included positive margin status (hazard ratio [HR], 2.20; P < .001), multiple lesions (HR, 1.80; P = .001), and vascular invasion (HR, 1.59; P = .015). Tumor size was not a prognostic factor (HR, 1.03; P = .23). Patients were stratified using the American Joint Committee on Cancer/International Union Against Cancer T1, T2a, and T2b categories (seventh edition) in a discrete step-wise fashion (P < .001). Lymphadenectomy was performed in 248 patients (55%); 74 of these (30%) had LN metastasis. LN metastasis was associated with worse outcome (median survival: N0, 30 months v N1, 24 months; P = .03). Although patients with no LN metastasis were able to be stratified by tumor number and vascular invasion (N0; P < .001), among patients with N1 disease, multiple tumors and vascular invasion, either alone or together, failed to discriminate patients into discrete prognostic groups (P = .34). Conclusion Although tumor size provides no prognostic information, tumor number, vascular invasion, and LN metastasis were associated with survival. N1 status adversely affected overall survival and also influenced the relative effect of tumor number and vascular invasion on prognosis. Lymphadenectomy should be strongly considered for ICC, because up to 30% of patients will have LN metastasis.

Introduction Data on recurrence after operation for intrahepatic cholangiocarcinoma (ICC) are limited. We sought to investigate rates and patterns of recurrence in patients after operative intervention for ICC. Methods We identified 301 patients who underwent operation for ICC between 1990 and 2011 from an international, multi-institutional database. Clinicopathologic data, recurrence patterns, and recurrence-free survival (RFS) were analyzed. Results During the median follow up duration of 31 months (range 1–208), 53.5% developed a recurrence. Median RFS was 20.2 months and 5-year actuarial disease-free survival, 32.1%. The most common site for initial recurrence after operation of ICC was intrahepatic (n = 98; 60.9%), followed by simultaneous intra- and extrahepatic disease (n = 30; 18.6%); 33 (21.0%) patients developed extra-hepatic recurrence only as the first site of recurrence. Macrovascular invasion (hazard ratio [HR], 2.08; 95% confidence interval [CI], 1.34–3.21; P <.001), nodal metastasis (HR, 1.55; 95% CI, 1.01–2.45; P = .04), unknown nodal status (HR, 1.57; 95% CI, 1.10–2.25; P = .04), and tumor size ≥5 cm (HR, 1.84; 95% CI, 1.28–2.65; P <.001) were independently associated with increased risk of recurrence. Patients were assigned a clinical score from 0 to 3 according to the presence of these risk factors. The 5-year RFS for patients with scores of 0, 1, 2, and 3 was 61.8%, 36.2%, 19.5%, and 9.6%, respectively. Conclusion Recurrence after operative intervention for ICC was common. Disease recurred both at intra-and extrahepatic sites with roughly the same frequency. Factors such as lymph node metastasis, tumor size, and vascular invasion predict highest risk of recurrence.

We conducted an international, prospective, 3-year questionnaire-based survey among 11 pulmonary hypertension centres to assemble data from patients with pulmonary arterial hypertension (PAH) undergoing noncardiac and nonobstetric surgery.Data were collected between July 2007 and June 2010 from 114 patients with PAH (70% female, mean age 57 years) who underwent major surgery. At the time of surgery, 43% were in functional class III/IV. 82% of the interventions were performed under general anaesthesia and 18% under spinal anaesthesia. Major complications occurred in seven (6.1%) of the patients, of whom four died, resulting in an overall perioperative mortality rate of 3.5%. The mortality rate was 15% (two out of 13) in emergency procedures, compared with 2% (two out of 101) in nonemergency procedures (p50.01). Risk factors for major complications were an elevated right atrial pressure (OR 1.1, 95% CI 1.0-1.3; p50.01), a 6-min walking distance ,399 m at the last preoperative assessment (OR 2.2, 95% CI 1.1-3.7; p50.04), the perioperative use of vasopressors (OR 1.5, 95% CI 1.2-2.7; p50.03) and the need for emergency surgery (OR 2.4, 95% CI 1.4-3.6; p50.01).Major surgery in patients with PAH continues to be a high-risk procedure, particularly when emergency interventions are needed.

Consistent with retrospective studies of patients with first-episode psychosis, findings revealed frequent mood and anxiety disturbance during the prodromal phase of illness. The DSM-IV does not offer a clear framework for describing the widespread subthreshold symptomatology that characterizes putatively prodromal patients. The authors consider whether the psychosis prodrome merits designation as a recognized clinical entity.
