Abstract
BACKGROUND The incidence of gastric poorly cohesive carcinoma (PCC) is increasing. The prognosis for patients with peritoneal metastases remains poor and the role of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is controversial. The aim was to clarify the impact of gastric PCC with peritoneal metastases treated by CRS with or without HIPEC. METHODS All patients with peritoneal metastases from gastric cancer treated with CRS with or without HIPEC, in 19 French centres, between 1989 and 2014, were identified from institutional databases. Clinicopathological characteristics and outcomes were compared between PCC and non-PCC subtypes, and the possible benefit of HIPEC was assessed. RESULTS In total, 277 patients were included (188 PCC, 89 non-PCC). HIPEC was performed in 180 of 277 patients (65 per cent), including 124 of 188 with PCC (66 per cent). Median overall survival (OS) was 14.7 (95 per cent c.i. 12.7 to 17.3) months in the PCC group versus 21.2 (14.7 to 36.4) months in the non-PCC group (P < 0.001). In multivariable analyses, PCC (hazard ratio (HR) 1.51, 95 per cent c.i. 1.01 to 2.25; P = 0.044) was associated with poorer OS, as were pN3, Peritoneal Cancer Index (PCI), and resection with a completeness of cytoreduction score of 1, whereas HIPEC was associated with improved OS (HR 0.52; P < 0.001). The benefit of CRS-HIPEC over CRS alone was consistent, irrespective of histology, with a median OS of 16.7 versus 11.3 months (HR 0.60, 0.39 to 0.92; P = 0.018) in the PCC group, and 34.5 versus 14.3 months (HR 0.43, 0.25 to 0.75; P = 0.003) in the non-PCC group. Non-PCC and HIPEC were independently associated with improved recurrence-free survival and fewer peritoneal recurrences. In patients who underwent HIPEC, PCI values of below 7 and less than 13 were predictive of OS in PCC and non-PCC populations respectively. CONCLUSION In selected patients, CRS-HIPEC offers acceptable outcomes among those with gastric PCC and long survival for patients without PCC.

Initial experience of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in a French hyperthermic intraperitoneal chemotherapy (HIPEC) expert center. Surg Endosc 2020; 34:2803-2806. [PMID: 32166545 DOI: 10.1007/s00464-020-07488-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 03/02/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new intraabdominal technique to approach non-resectable peritoneal carcinomatosis (PC). PIPAC can be performed alone or alternated with systemic chemotherapy to increase tumor regression. We describe our initial experience performed in an expert hyperthermic intraperitoneal chemotherapy (HIPEC) French center to demonstrate the safety and the feasibility of PIPAC. METHODS Between January 2016 and March 2019, PIPAC was proposed to 43 consecutive patients affected by digestive, ovarian, peritoneal and mammary carcinomatosis. Initially PIPAC was proposed to patients non eligible for cytoreductive surgery for palliative purposes. In five patients we associated PIPAC to systemic chemotherapy to improve tumor regression and enhance the chance of patients to undergo HIPEC. Three PIPAC treatments were supposed to be performed for each patient with an interval of 6 weeks in between each procedure. Peritoneal biopsies were always performed to evaluate microscopic tumor regression. In case of postoperative clinical deterioration or quick tumor progression during the cycles, PIPAC was interrupted. Depending on the primary tumor, chemotherapies used were oxaliplatin or a combination of cisplatin and doxorubicin. RESULTS Twenty-six (60.4%) patients have already had a surgical resection or intervention of primary cancer removal. In 5 patients abdominal access was impossible. Of the 38 patients operated, seventy-one procedures were performed. In the series, one patient died because of tumor progression. Only one major complication occurred intraoperatively. Two of thirteen patients receiving oxaliplatin had postoperative abdominal pain and needed more drugs assumption and a longer hospitalization. Three patients after a three cycles procedure underwent HIPEC. Nine of the patients who had at least two PIPACs had last biopsies showing a major or complete tumor response. CONCLUSION PIPAC is a safe and feasible procedure that can be performed in patients with peritoneal carcinomatosis initially not eligible for surgery to reduce tumor invasion or for palliation to reduce symptoms. Contraindications are bowel obstruction and multiple intraabdominal adhesions.

Can machine learning predict resecability of a peritoneal carcinomatosis? Surg Oncol 2019; 29:120-125. [PMID: 31196475 DOI: 10.1016/j.suronc.2019.04.008] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2019] [Accepted: 04/28/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Approximately 20% of initially eligible patients in a HIPEC procedure eventually underwent a simple surgical exploration. These procedures are called 'open & close' (O & C) representing up to 48% of surgery. The objective of this study was to predict the resecability of peritoneal carcinomatosis using a machine-learning model for decision-making support, for eligible patients of HIPEC. METHODS The study was conducted as an intention to treat based on three databases including a prospective, between January 2000 and December 2015. A propensity score allowed us to obtain two groups of comparable and matched patients. Subsequently, several algorithm models of classification were studied (simple classification, conditional tree, support vector machine, random forest) to determine the model having the best performance and accuracy. RESULTS Two groups of 155 patients were obtained: one group without resection and one group with resection. Nine criteria of non-resecability reflecting the organ involvement have been retained. They were coded according to their importance. Five classification algorithms were tested. The training data included 218 patients and 92 test data. The random forest model exhibited the best performance with an accuracy of close to 98%. Only two errors of predictions were observed. DISCUSSION The largest number of patients will allow us to improve the precision prediction. Gathering more data such as biologic, radiologic, and even laparoscopic features, should improve the knowledge of the disease and decrease the number of 'O & C' procedures.

Diffuse malignant peritoneal mesothelioma: Evaluation of systemic chemotherapy with comprehensive treatment through the RENAPE Database: Multi-Institutional Retrospective Study. Eur J Cancer 2016; 65:69-79. [PMID: 27472649 DOI: 10.1016/j.ejca.2016.06.002] [Citation(s) in RCA: 59] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2016] [Revised: 05/26/2016] [Accepted: 06/01/2016] [Indexed: 12/12/2022]
Abstract
PURPOSE Diffuse malignant peritoneal mesothelioma (DMPM) is a severe disease with mainly locoregional evolution. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is the reported treatment with the longest survival. The aim of this study was to evaluate the impact of perioperative systemic chemotherapy strategies on survival and postoperative outcomes in patients with DMPM treated with curative intent with CRS-HIPEC, using a multi-institutional database: the French RENAPE network. PATIENTS AND METHODS From 1991 to 2014, 126 DMPM patients underwent CRS-HIPEC at 20 tertiary centres. The population was divided into four groups according to perioperative treatment: only neoadjuvant chemotherapy (NA), only adjuvant chemotherapy (ADJ), perioperative chemotherapy (PO) and no chemotherapy before or after CRS-HIPEC (NoC). RESULTS All groups (NA: n = 42; ADJ: n = 16; PO: n = 16; NoC: n = 48) were comparable regarding clinicopathological data and main DMPM prognostic factors. After a median follow-up of 61 months, the 5-year overall survival (OS) was 40%, 67%, 62% and 56% in NA, ADJ, PO and NoC groups, respectively (P = 0.049). Major complications occurred for 41%, 45%, 35% and 41% of patients from NA, ADJ, PO and NoC groups, respectively (P = 0.299). In multivariate analysis, NA was independently associated with worse OS (hazard ratio, 2.30; 95% confidence interval, 1.07-4.94; P = 0.033). CONCLUSION This retrospective study suggests that adjuvant chemotherapy may delay recurrence and improve survival and that NA may impact negatively the survival for patients with DMPM who underwent CRS-HIPEC with curative intent. Upfront CRS and HIPEC should be considered when achievable, waiting for stronger level of scientific evidence.

Patients with Peritoneal Carcinomatosis from Gastric Cancer Treated with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: Is Cure a Possibility? Ann Surg Oncol 2016; 23:1971-9. [PMID: 26753751 DOI: 10.1245/s10434-015-5081-3] [Citation(s) in RCA: 94] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Indexed: 12/14/2022]
Abstract
BACKGROUND Peritoneal carcinomatosis is an increasingly common finding in gastric carcinoma. Previously, patients were treated as terminal, and median survival was poor. The use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in this context is still highly debatable. OBJECTIVE The aim of this study was to evaluate the long-term outcomes associated with CRS and HIPEC, and define prognostic factors for cure, if possible. PATIENTS AND METHODS All patients with gastric carcinomatosis from five French institutions who underwent combined complete CRS and HIPEC and had a minimum follow-up of 5 years were included in this study. Cure was defined as a disease-free interval of more than 5 years from the last treatment until the last follow-up. RESULTS Of the 81 patients who underwent CRS and HIPEC from 1989 to 2009, 59 had a completeness of cytoreduction score (CCS) of 0 (complete macroscopic resection), and the median Peritoneal Cancer Index (PCI) score was 6. Mitomycin C was the most commonly used drug during HIPEC (88 %). The 5-year overall survival (OS) rate was 18 %, with nine patients still disease-free at 5 years, for a cure rate of 11 %. All 'cured' patients had a PCI score below 7 and a CCS of 0. Factors associated with improved OS on multivariate analysis were synchronous resection (p = 0.02), a lower PCI score (p = 0.12), and the CCS (p = 0.09). CONCLUSION The cure rate of 11 % for patients with gastric carcinomatosis who are deemed terminal emphasizes that CRS and HIPEC should be considered in highly selected patients (low disease extent and complete CRS).

Professional risks when carrying out cytoreductive surgery for peritoneal malignancy with hyperthermic intraperitoneal chemotherapy (HIPEC): A French multicentric survey. Eur J Surg Oncol 2015; 41:1361-7. [PMID: 26263848 DOI: 10.1016/j.ejso.2015.07.012] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2015] [Revised: 07/10/2015] [Accepted: 07/15/2015] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Over the last two decades, many surgical teams have developed programs to treat peritoneal carcinomatosis with extensive cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). Currently, there are no specific recommendations for HIPEC procedures concerning environmental contamination risk management, personal protective equipment (PPE), or occupational health supervision. METHODS A survey of the institutional practices among all French teams currently performing HIPEC procedures was carried out via the French network for the treatment of rare peritoneal malignancies (RENAPE). RESULTS Thirty three surgical teams responded, 14 (42.4%) which reported more than 10 years of HIPEC experience. Some practices were widespread, such as using HIPEC machine approved by the European Community (100%), individualized or centralized smoke evacuation (81.8%), "open" abdominal coverage during perfusion (75.8%), and maintaining the same surgeon throughout the procedure (69.7%). Others were more heterogeneous, including laminar flow air circulation (54.5%) and the provision of safety protocols in the event of perfusate spills (51.5%). The use of specialized personal protective equipment is ubiquitous (93.9%) but widely variable between programs. CONCLUSION Protocols regarding cytoreductive surgery/HIPEC and the associated professional risks in France lack standardization and should be established.

Hyperthermic intraperitoneal chemotherapy leads to an anticancer immune response via exposure of cell surface heat shock protein 90. Oncogene 2015; 35:261-8. [PMID: 25867070 DOI: 10.1038/onc.2015.82] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2014] [Revised: 02/20/2015] [Accepted: 02/22/2015] [Indexed: 01/13/2023]
Abstract
The occurrence of peritoneal carcinomatosis is a major cause of treatment failure in colorectal cancer and is considered incurable. However, new therapeutic approaches have been proposed, including cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC). Although HIPEC has been effective in selected patients, it is not known how HIPEC prolongs a patient's lifespan. Here, we have demonstrated that HIPEC-treated tumor cells induce the activation of tumor-specific T cells and lead to vaccination against tumor cells in mice. We have established that this effect results from the HIPEC-mediated exposure of heat shock protein (HSP) 90 at the plasma membrane. Inhibition or blocking of HSP90, but not HSP70, prevented the HIPEC-mediated antitumoral vaccination. Our work raises the possibility that the HIPEC procedure not only kills tumor cells but also induces an efficient anticancer immune response, therefore opening new opportunities for cancer treatment.

Abstract
Secondary localization to vagina had a severe prognosis, suggesting a disseminated metatastic disease. We report the case of prevalent vaginal metastasis of adenocarcinoma of the transverse colon. A 65 years old patient has consulted for vaginal mass. After delayed diagnosis, she presented with disseminated metastatic disease with peritoneal carcinomatosis. After neoadjuvant chemotherapy, the following treatment consisted of complete cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy and vaginal adjuvant radiotherapy. No recurrence occurred after one year. Vaginal metastasis of colon cancer are rare. The dark prognosis might justify a systematic gynecological examination of women presenting colorectal neoplasy.

Abstract
BACKGROUND Despite a high response rate to front-line therapy, prognosis of epithelial ovarian carcinoma (EOC) remains poor. Approaches that combine Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) have been developed recently. The purpose of this study was to assess early and long-term survival in patients treated with this strategy. PATIENTS AND METHODS A retrospective cohort multicentric study from French centres was performed. All consecutive patients with advanced and recurrent EOC treated with CRS and HIPEC were included. RESULTS The study included 566 patients from 13 centres who underwent 607 procedures between 1991 and 2010. There were 92 patients with advanced EOC (first-line treatment), and 474 patients with recurrent EOC. A complete cytoreductive surgery was performed in 74.9% of patients. Mortality and grades 3 to 4 morbidity rates were 0.8% and 31.3%, respectively. The median overall survivals were 35.4 months and 45.7 months for advanced and recurrent EOC, respectively. There was no significant difference in overall survival between patients with chemosensitive and with chemoresistant recurrence. Peritoneal Cancer Index (PCI) that evaluated disease extent was the strongest independent prognostic factor for overall and disease-free survival in all groups. CONCLUSION For advanced and recurrent EOC, curative therapeutic approach combining optimal CRS and HIPEC should be considered as it may achieve long-term survival in patients with a severe prognosis disease, even in patients with chemoresistant disease. PCI should be used for patient's selection.

Abstract
AIM Primary peritoneal serous carcinoma (PPSC) is a rare condition, histologically identical to ovarian serous carcinoma and often diagnosed at late stage. There is not any standardized treatment for PPSC. A retrospective multicentric study was performed in French speaking centers to evaluate cytoreduction surgery and Hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal carcinomatosis from different origins. The manuscript's aim was to study the particular population with PPSC. METHODS Between September 1997 and July 2007, 36 patients with PPSC from 9 institutions underwent 39 procedures. RESULTS Mortality and morbidity rates were 5.6% and 20.6% respectively. The overall survival at 1, 3 and 5 years are respectively 93.6, 71.5 and 57.4%. The median overall survival was not reached. By univariate analysis, the only factor that had prognostic value was PCI (p = 0.03). CONCLUSIONS The therapeutic approach combining cytoreductive surgery with HIPEC may achieve long-term survival in patients with PPSC.

Abstract
BACKGROUND Epithelial ovarian carcinoma is the main cause of death from gynaecological cancers in the western world. The initial response rate to the frontline therapy is high. However, the prognosis of persistent and recurrent disease remains poor. During the two past decades, a new therapeutic approach to peritoneal carcinomatosis has been developed, combining maximal cytoreductive effort with hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS A retrospective, multicentric study of 246 patients with recurrent or persistent ovarian cancer, treated by cytoreductive surgery and HIPEC in two French centers between 1991 and 2008, was performed. RESULTS An optimal cytoreductive surgery was possible in 92.2 % of patients. Mortality and morbidity rates were 0.37 % and 11.6 %, respectively. The overall median survival was 48.9 months. There was no significant difference in overall survival in patients with persistent or recurrent disease. In multivariate analysis, performance status was a significant prognostic factor in patients with extensive peritoneal carcinomatosis (peritoneal cancer index >10). CONCLUSIONS Salvage therapy combining optimal cytoreductive surgery and HIPEC is feasible and may achieve long-term survival in highly selected patients with recurrent ovarian carcinoma, including those with platinum resistant disease, with acceptable morbidity.

Abstract
OBJECTIVE To analyze a large series of patients with pseudomyxoma peritonei (PMP) treated with cytoreductive surgery associated with perioperative intraperitoneal chemotherapy (PIC) in 18 French-speaking centers. PATIENTS AND METHODS From March 1993 to December 2007, 301 patients with diffuse PMP were treated by cytoreductive surgery with PIC. Complete cytoreductive surgery was achieved in 219 patients (73%), and hyperthermic intraperitoneal chemotherapy (HIPEC) was performed in 255 (85%), mainly during the latter period of the study. RESULTS Postoperative mortality and morbidity were 4.4% and 40%, respectively. The mean follow-up was 88 months. The 5-year overall and disease-free survival rates were 73% and 56%, respectively. The multivariate analysis identified 5 prognostic factors: the extent of peritoneal seeding (p=0.004), the center (p=0.0004), the pathologic grade (p=0.03), gender (p=0.02), and the use of HIPEC (p=0.04). When only the 206 patients with complete cytoreductive surgery were considered, the extent of peritoneal seeding was the only significant prognostic factor (p=0.004). CONCLUSION This large multicentric retrospective study confirms that cytoreductive surgery combined with PIC (with the use of hyperthermia) should be considered as the gold standard treatment of PMP and should be performed in specialized centers. It underlines the prognostic impact of the extent of peritoneal seeding, especially in patients treated by complete cytoreductive surgery. This prognostic impact appears to be greater than that of the pathologic grade.

Abstract
UNLABELLED Self-expanding metallic stents is an alternative treatment to colostomy that is the treatment of choice in acute tumoral left colonic obstruction. AIM OF THE STUDY To compare morbidity, mortality, length of hospital stay and treatment performed after desobstruction using the two methods. PATIENTS AND METHODS Thirty-three patients admitted for acute obstruction of the left colon were retrospectively separated in two groups depending on the type of intervention performed to treat the obstruction ("colostomy" group: 17 patients and "self-expanding stent group": 16 patients). We studied complications after desobstruction, hospital courses and surgical strategy performed after the acute phase. RESULTS Time between desobstruction and colectomy was shorter in the "self-expanding stent group" than in the "colostomy group" (18.5 days versus 73 days). Age superior than 75 years and colostomy were the two main factors predicting the risk of definitive colostomy (P < 0.05). Global mean hospital stay was longer in the colostomy group (32.7 days versus 19.3 days, P = 0.02). Two perforations and one local recurrence occurred in the "self-expanding stent group". CONCLUSIONS Self-expanding metallic stent can decrease the permanent colostomy rate and the number of interventions. The recurrence rate seems to be theoretically increased with the stenting method. Then, colostomy must be done for patients in curative situation. The self-expanding metallic stent should be used as a palliative care.

Abstract
PURPOSE The three principal studies dedicated to the natural history of peritoneal carcinomatosis (PC) from colorectal cancer consistently showed median survival ranging between 6 and 8 months. New approaches combining cytoreductive surgery and perioperative intraperitoneal chemotherapy suggest improved survival. PATIENTS AND METHODS A retrospective multicenter study was performed to evaluate the international experience with this combined treatment and to identify the principal prognostic indicators. All patients had cytoreductive surgery and perioperative intraperitoneal chemotherapy (intraperitoneal chemohyperthermia and/or immediate postoperative intraperitoneal chemotherapy). PC from appendiceal origin was excluded. RESULTS The study included 506 patients from 28 institutions operated between May 1987 and December 2002. Their median age was 51 years. The median follow-up was 53 months. The morbidity and mortality rates were 22.9% and 4%, respectively. The overall median survival was 19.2 months. Patients in whom cytoreductive surgery was complete had a median survival of 32.4 months, compared with 8.4 months for patients in whom complete cytoreductive surgery was not possible (P <.001). Positive independent prognostic indicators by multivariate analysis were complete cytoreduction, treatment by a second procedure, limited extent of PC, age less than 65 years, and use of adjuvant chemotherapy. The use of neoadjuvant chemotherapy, lymph node involvement, presence of liver metastasis, and poor histologic differentiation were negative independent prognostic indicators. CONCLUSION The therapeutic approach combining cytoreductive surgery with perioperative intraperitoneal chemotherapy achieved long-term survival in a selected group of patients with PC from colorectal origin with acceptable morbidity and mortality. The complete cytoreductive surgery was the most important prognostic indicator.

Abstract
PURPOSE To determine maximum tolerated dose, safety and efficacy of weekly 24 h infusional 5-fluorouracil (5-FU) combined alternately with oxaliplatin and irinotecan. PATIENTS AND METHODS Advanced colorectal carcinoma patients in first- or second-line chemotherapy received increasing doses of 5-FU (weekly 24 h continuous intravenous infusion without leucovorin) on days 1, 8, 15 and 22, irinotecan days 1 and 15; and oxaliplatin days 8 and 22, every 35 days. RESULTS Thirty-four patients received 175 cycles. The median age was 64 years (range 47-78). Eighteen per cent of patients had the primary tumor in the rectum, with a median of one disease site (range one to three), and liver involvement in 88% and lung in 38%. Six (18%) patients had chemotherapy for prior advanced disease. The most frequent grade 3-4 toxicity was neutropenia (41% of patients), but the regimen was well tolerated clinically, with febrile neutropenia in two patients and grade 4 neutropenia lasting >7 days in one; grade 3-4 diarrhea, nausea and vomiting in 6% of patients; grade 3-4 peripheral neuropathy in 9% of patients. Seventeen patients had a partial response (50%; 95% confidence interval 33%-67%), 13 had stable disease and one had progressive disease. Five patients underwent metastatic surgical resection after tumor shrinkage. Median response duration was 14 months (range 4.7-29.2+) and median time to progression was 11.3 months (range 1.1+-30.7+). CONCLUSIONS This combination three-drug regimen is feasible and well tolerated without toxicity overlap. Preliminary antitumor activity compares well with standard double combinations, with an unusually long median time to progression. The recommended dose is 5-FU 3000 mg/m(2), weekly for 4 weeks, irinotecan 100 mg/m(2) days 1 and 15, oxaliplatin 80 mg/m(2) days 8 and 22. Further assessment of antitumor activity and safety is warranted.

Abstract
Obstetrical hemorrhage is a severe complication with vital prognosis at stake. Treatment depends on aetiology: a surgical procedure may be indicated initially or after failure of medical management. Radical treatment with hemostasis hysterectomy is generally successful. However, in case of persistent hemorrhage after hysterectomy, other means are available such as pelvic tamponade.

Abstract
Ingestion of foreign bodies is a common happening for prison inmates. When such bodies do not pass, endoscopic or surgical retrieval is necessary. The authors report the case of a young patient in whom endoscopy failed to retrieve several intragastric foreign bodies. He was treated successfully by laparoscopic gastrotomy. The authors think that this approach is a valid alternative to laparotomy.

Abstract
The prevalence of splenic metastasis from carcinomas varies between 2% and 13% in autopsy studies. Most of them are clinically inapparent. We report herein the case of a splenic metastasis revealing breast carcinoma in a 73-year old woman. Splenectomy was performed to correct hypersplenism. Macroscopically, the cut surface of the spleen was uniform and pale. On microscopical examination, the metastatic infiltration involved both red and white pulp as single cells, cords and micro-nodules. Tumor cells were positive for cytokeratin and epithelial membrane antigen (EMA). The breast origin of this splenic metastasis was supported by the increase of CA 15-3 level, and by the appearance of axillary lymphadenopathy. In addition, the red pulp sinuses were obliterated by multiple thrombi at different stages of development and the splenic cords were collagenized. These changes could result from an unusual stromal reaction.

Abstract
The aim of this study was to examine the results of a policy in the treatment of acute pancreatitis (AP): initial abstention, management in intensive care unit, surgery in cases of complication (infection and/or failure of medical treatment). The modalities of the surgical treatment were guided by CT scan findings: transperitoneal approach for diffuse lesions, posterior approach for localized lesions. From 1986 to 1994, 57 patients (32 males, 25 females, mean age 59.2 years) were referred to our department for AP. Etiology was gallstones in 29 cases, alcohol in 14 cases (Ranson < 3), moderate in 27 cases (Ranson < or = 5) and serious in 12 cases (Ranson > or = 6). According to the initial CT scan findings (56 cases), 9 patients were classified grade A, 11 grade B, 13 grade C, 8 grade D ans 15 grade E. Thirty eight patients were managed conservatively (mean Ranson stage 3.3), while 19 patients underwent surgical treatment (mean Ranson stage 4.6), in emergency for misdiagnosis (4 cases), or secondarily because of failure of medical management (15 cases). Surgery consisted in necrosectomy with active drainage in 13 cases and drainage alone in 6 cases. Associated maneuvers included: cholecystectomy in 8 cases, cholecystostomy in 2 cases, jejunostomy in 7 cases and colic resection for necrosis in 3 cases. Two patients (5%) managed conservatively died (multiple organ failure and cardiac insufficiency) while 4 patients (21%: NS) who underwent surgery died (2 multiple organ failures, 1 septic shock, 1 myocardic infarction). Mortality was correlated with the Ranson score: 42% for serious AP, 3.7% for moderate AP and nil for mild AP (p < 0.01). It was not correlated with CT scan grade, the onset or the type of operation. These results allow us to conclude that surgical treatment should be indicated only in cases of failure of conservative management, the best indication being uncontrolled sepsis. In this situation, active drainage provides good results since only one sepsis recurred among the 14 patients who underwent this procedure.

Abstract
From 1973 to 1987, 33 patients aged from 46 to 86 years (25 female, 8 male) were treated for a tumour of the anal canal with radiotherapy and curietherapy. Tumour distribution was 7 T1, 19 T2, 7 T3, and 4 patients were N+. After treatment it was possible to assess 31 patients; 29 were in complete remission, remission was obtained in 2 others following surgery. Tolerance was comparable to other series but 4 patients developed necrosis of the anal canal; 2 patients died under general anesthesia and 1 patient had a radiation injury of the small intestine. The sphincter was conserved in 65 p. cent of cases. Relapse occurred in 8 patients within 6-92 months, and 6 patients developed metastases. Overall survival was 78 p. cent at 3 years and 74 p. cent at 5 and 10 years. Disease-free survival was 65 p. cent at 3 and 5 years and 52 p. cent at 10 years. Our results confirm those of other series using a similar treatment plan. This treatment is difficult to put into practice. Patients must be carefully selected preferably by a team including proctologist, surgeon and radiotherapist.
