"Sugar" tumor of the pancreas: a rare entity that is diagnosable on preoperative fine-needle biopsies.

This study is the second to report a pancreatic "sugar" tumor (ST) case. This ST was incidentally discovered in a 31-year-old woman using computed tomography scan (CT scan) for work-up of a hepatic focal nodular hyperplasia. Both CT scan and endoluminal ultrasonography (EUS) features evoked a 15-mm large benign endocrine tumor. Pathological examination of EUS-guided fine-needle aspiration biopsies could not confirm this diagnosis. Laparoscopic corporeo-caudal pancreatectomy was performed. The tumor was intrapancreatic, well circumscribed, and organized in sheets of epithelioid cells. The tumor cells expressed HMB-45 but did not express epithelial or endocrine immunohistochemical markers. These histophenotypic features are those of an extra pulmonary ST, which belong to the PEComa family of tumors. Retrospective examination of preoperative biopsies evidenced the same histophenotypic features. This observation highlights that STs should be considered in preoperative differential diagnosis of pancreas tumors, since they may be treated by limited surgical resection.

Hemorrhage after duodenopancreatectomy: impact of neoadjuvant radiochemotherapy and experience with sentinel bleeding.

Postoperative hemorrhage (PH) after duodenopancreatectomy (DP) is frequently lethal. The aim of this study was to delineate guidelines of management. Between August 1994 and July 2003, 172 patients underwent DP for cancer. Altogether, 26 patients were subjected to an institutional protocol (IP) with standard-dose chemoradiation (CRT) and 4 patients to an extrainstitutional protocol (EIP) with high-dose CRT. Sixteen patients (9.3%) were reoperated for PH. Hemorrhage occurred in 23% of irradiated patients (4 EIP, 3 IP) and in 6% of nonirradiated patients [confidence interval (CI) 1.8-6.5]. Pancreatic leak occurred in nine patients with PH (56%). Sentinel bleeding (SB) was noted in eight patients (50%) with a mean delay of 10 days after DP. Overall mortality after hemorrhage was 56%. Morality rates of patients with EIP or IP were, respectively, 100% and 0%. Mortality rates of patients with or without SB were similar. Mortality rates of axial bleeding (hepatic artery, mesenteric vessels) or lateral bleeding (pancreas remnant, splenic vessels) were, respectively, 88% and 25% (CI 1.6-8.6). Completion of pancreatectomy was achieved in 75% without rebleeding. Preoperative high-dose CRT increased the risk of fatal PH. Because SB occurs before massive hemorrhage, prompt reoperation could reduce mortality. Completion of pancreatectomy was essential during reintervention. Axial bleeding supports high mortality. Moving to the left, the pancreatojejunostomy could avoid contact of pancreatic juice with axial vessels in the case of pancreatic leakage. Ligating the gastroduodenal artery during DP had to leave a stump of around 1 cm to facilitate hemorrhage control without ligating the common hepatic artery.

Salvage abdominoperineal resection after failure of conservative treatment in anal epidermoid cancer.

PURPOSE: Radiotherapy alone or with combined chemotherapy is the first therapeutic option for epidermoid carcinoma of the anal canal. Failure of this conservative treatment may benefit of salvage abdominoperineal resection. This study was designed to analyze postoperative outcome and oncologic results in a single anticancer institution. METHODS: Medical charts of 36 patients (median age, 57.9 years) who underwent salvage abdominoperineal resection after failure of conservative treatment between 1987 and 2002 were reviewed retrospectively. There were 15 patients treated for immediate failure (Group I) and 21 patients for recurrence (Group II). Twenty-two patients have undergone primary use of flap reconstruction of the perineal wound. There were ten rectus abdominis myocutaneous flaps, nine omental flaps, two gracilis muscular flaps, and one combined flap. RESULTS: There was no postoperative mortality. Median follow-up was 67 (range, 15-155) months. Primary closure of the perineum was obtained in 33 patients (92 percent). Secondary wound breakdown occurred in 23 of 33 patients (70 percent). Complications unrelated to the perineal wound occurred in 13 patients. The overall crude five-year survival after salvage abdominoperineal resection was 69.4 percent. The crude five-year survival in Group I and Group II was 60.7 and 71.5 percent respectively (P = 0.28). The crude five-year, disease-free survival in Groups I and II was 31.1 and 48.2 percent respectively (P = 0.10). Twenty-three patients experienced recurrences after salvage abdominoperineal resection (64 percent) with a mean delay of 30 months. CONCLUSIONS: Despite high incidence of perineal morbidity, salvage abdominoperineal resection for epidermoid carcinomas of the anal canal has a high long-term survival rate.

Long-term follow-up of continent urinary diversion after pelvic exenteration for gynecologic malignancies.

OBJECTIVE: The objective of this retrospective study was to analyze the long-term outcome of patients undergoing a continent urinary diversion (UD) at the time of pelvic exenteration (PE). PATIENTS AND METHODS: Between February 1993 and January 2001, 60 PE for gynecologic malignancies and requiring a UD were performed. Patient's preference, type of UD planned, type of UD performed, and late urinary morbidity (after day 90) were analyzed. RESULTS: Eighty-two percent of the entire group (49/60) matched preoperatively criteria to have a continent UD and 41 continent UD were eventually performed (87%). Postoperative mortality in patients with a continent UD was 4.9% (2/41) and wasn't related to urinary complications. After a 20-month median follow-up, 18 patients (46%) with a continent UD developed late complications directly UD-related. These complications were: (a) major in 28% (5/18) requiring re-operation in 3 cases or endoscopic treatment in 2 cases; (b) minor in 72% (13/18) constantly medically treated. Chronic diarrhea was more frequent in patient who had small bowel or left colon resection (P < 0.05) and urine leakage was more frequent in patient with higher BMI (P < 0.05). At last follow-up, no patient had stopped self-catheterizations or asked for undiversion. CONCLUSIONS: In our experience, continent UD at the time of PE despite high acceptability and feasibility rate, appeared to be strongly related to specific late complications, uncommon with ileal conduit. However, these complications remained more frequently minor and could be treated safely and conservatively.

Assessment of pathologic response after preoperative chemoradiotherapy and surgery in pancreatic adenocarcinoma.

PURPOSE: The benefits provided by preoperative chemoradiotherapy (CRT) in pancreatic ductular adenocarcinoma (PDA) are still controversial. However, in most reports from referral centers, improvement in local control and survival appears to be provided in selected patients. The aim of this retrospective study was to analyze the radiation-induced pathologic effects of preoperative CRT in patients with resectable PDA and determine the precise long-term outcome of the responding patients. METHODS AND MATERIALS: Between November 1996 and October 2003, 61 patients underwent preoperative CRT for resectable PDA. The tumor location was the pancreatic head in 49 patients and pancreatic body in 12 patients. Of the 61 patients, 21 (34.5%) did not undergo surgery because of disease progression and 40 (65.5%) underwent pancreatic resection, including pancreaticoduodenectomy in 32 (80%) and distal pancreatectomy in 8 (20%). RESULTS: A major pathologic response was noted in 9 patients, including three complete responses, and was found only in patients with tumor of the pancreatic head. The local control rate was similar in patients with and without a major pathologic response. Survival in patients with a major response was significantly greater than in those without a response or with a minor response. CONCLUSION: Major tumor downstaging can be provided by preoperative CRT in patients with resectable cephalic PDA. Survival appears to be significantly improved in selected patients.

[Colorectal cancer: what should be the management of primary tumour?].

Colon and rectal cancer are in France a challenging problem in public health, reaching the second place in cancer related deaths. Surgery is still the key of curative treatment. Crude survival increased from 33% to 55% during twenty years. Colonoscopy is the referent exam for positive diagnosis. In rectal cancer, endorectal ultrasound and MRI have optimised local staging. The quality of general staging is important since it could change therapeutic strategy. Spiral CT scan is now probably superior to conventional ultrasound in the detection of liver metastases. Laparotomy is still the standard surgical approach. Main prospective studies in the evaluation of laparoscopic approach are still ongoing. Rectal resection for cancer is today a standardised procedure: total mesorectal excision (TME) should be done for rectal tumours below peritoneal reflection; TME decreases both the risk of local recurrence and the frequency of urogenital sequelae. The quality of surgical resection for colorectal cancer should always be checked and particularly, the number of lymph nodes, the longitudinal and lateral margins for rectal cancer, and resection for fixed tumours. Adjuvant chemotherapy with 5 fluorouracil and folinic acid is a standard for UICC stage III patients, but with a clearer benefit for colon tumours. Preoperative irradiation for T3-T4 rectal tumours is an European standard, providing a better local control; irradiation could also improved survival. In the oncoming years, surgeon and hospital specialization will probably be the main factor of progress in the management of colorectal cancer in France.

Neoadjuvant preoperative chemoradiation in patients with pancreatic cancer.

PURPOSE: To assess the toxicity and efficacy of preoperative chemoradiation in pancreatic cancer. METHODS AND MATERIALS: Between November 1996 and December 2001, 32 patients with biopsy-proven pancreatic adenocarcinoma (28 head; 4 body) were treated by chemoradiation consisting of either split-course therapy (two courses of 15 Gy separated by a 2-week break, n = 10) or standard-fractionation therapy (45 Gy during 5 weeks, n = 22). Concurrent chemotherapy included continuous infusion of 5-fluorouracil and a cisplatin bolus. Pancreatic resection was scheduled for 4-6 weeks after completion of chemoradiation treatment. RESULTS: All 32 patients completed the chemoradiation protocol. Only 2 cases of Grade 3 toxicity (weight loss, vomiting) and one fatal Grade 4 infection occurred. Of the 32 patients, 19 underwent curative resection. Two patients had a complete pathologic response. One patient died 36 months after diagnosis of late treatment-related toxicity (acute superior mesenteric artery thrombosis) with no evidence of disease. The 2-year overall survival rate for the entire group and the resected patients was 37.3% (95% confidence interval 18.2-56.4%) and 59.3% (95% confidence interval 34.1-84.9%), respectively. CONCLUSION: Preoperative chemoradiation with 5-fluorouracil and cisplatin is feasible and promising.

[Results of heart transplantation: experience of 233 grafts].

BACKGROUND: Heart failure is one of the leading causes of hospitalization and death. The aim of this study was to evaluate long term outcomes after cardiac transplantation. METHODS: A retrospective review of 222 consecutive cardiac allograft recipients who underwent 233 transplantations between 1986 to 2000 was undertaken. Cardiomyopathy (123) and ischemic heart disease (87) were the most common indications. Mean age was 51 years +/- 11, and male gender was predominant (184). RESULTS: 33 patients (14.8%) died in the post operative period, mainly from graft failure (24 pts). During the follow-up period (total 1157 pt/yrs, mean 6.2 +/- 5 yrs, max 16 yrs), 60 late deaths occurred from cancer (21), graft failure (13), infection (13), and miscellaneous (13). Retransplantations were performed in 11 patients. The actuarial survival of the entire cohort was 75%, 66% and 50% at 1, 5, and 10 years respectively. CONCLUSIONS: Cardiac transplantation gives satisfactory long term results for patients with end-stage heart failure, providing good exercise tolerance and survival for 10 years or more in a large number of patients. Improvement in immunosuppression therapy is responsible for decrease in acute rejection rate. Reduction in HLA mismatch should allow for better immunomodulation and decreased incidence of cardiac allograft vasculopathy and malignancies.

Locally advanced adenocarcinomas of the gastric cardia: results of pre-operative chemoradiotherapy.

UNLABELLED: Overall prognosis of adenocarcinomas of the gastro-esophageal junction remains poor as most patients present with advanced disease. AIM: To examine the effects of preoperative chemoradiotherapy in locally advanced adenocarcinomas of the gastro-esophageal junction. METHODS: Forty-two consecutive patients received a course of radiotherapy (45 Gy, administred in 25 fractions) with concurrent infusion of 5-Fluorouracil and cisplatin, followed by surgery. Endoscopic ultrasonography was used to assess response to chemoradiotherapy. A transhiatal or a transthoracic approach was used for surgical resection. Tumor size, node invasion and margins of resection were analyzed. RESULTS: Thirty-eight patients underwent subsequent surgery and complete resection (RO) was achieved in 34. Operative mortality was 13.2% (5/38). A histological complete response was observed in 6 patients. Median survival was 23 months (range: 15-31) and median disease-free survival was 19 months (range: 15-23). At one and two years, 70.7 and 45.6% of the patients were alive, respectively. The pTNM status, node involvement and tumor size were predictors of survival. CONCLUSIONS: Pre-operative chemoradiotherapy is effective in patients with locally advanced carcinoma of the gastro-esophageal junction, resulting in high resection rates. However it seems to increase operative morbidity and mortality. Certain prognostic factors such as resection margins, need to be examined in further detail.
