RESUMO

BACKGROUND: Peritoneal metastasis from biliary carcinoma (PMC) is associated with poor prognosis when treated with chemotherapy. OBJECTIVE: To evaluate the impact on survival of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), and compare with conventional palliative chemotherapy for patients with PMC. MATERIAL AND METHODS: A prospective multicenter international database was retrospectively searched to identify all patients with PMC treated with a potentially curative CRS/HIPEC (CRS/HIPEC group). The overall survival (OS) was compared to patients with PMC treated with palliative chemotherapy (systemic chemotherapy group). Survival was analyzed using Kaplan-Meier method and compared with Log-Rank test. RESULTS: Between 1995 and 2015, 34 patients were included in the surgical group, and compared to 21 in the systemic chemotherapy group. In the surgical group, median peritoneal cancer index was 9 (range 3-26), macroscopically complete resection was obtained for 25 patients (73%). There was more gallbladder localization in the surgical group compared to the chemotherapy group (35% vs. 18%, p = 0.001). Median OS was 21.4 and 9.3 months for surgical and chemotherapy group, respectively (p=0.007). Three-year overall survival was 30% and 10% for surgical and chemotherapy group, respectively. CONCLUSION: Treatment with CRS and HIPEC for biliary carcinoma with peritoneal metastasis is feasible and may provide survival benefit when compared to palliative chemotherapy.

RESUMO

Background and Aims. Intraperitoneal chemotherapy is a basic tool in the treatment of peritoneal malignancy. The purpose of the study is to investigate the effect of adjuvant perioperative intraperitoneal chemotherapy in the treatment of locally advanced colorectal cancer. Patients and Methods. Patients with T(3) and T(4) colorectal carcinomas that underwent R(0) resection received either hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC group = 40 patients) or early postoperative intraperitoneal chemotherapy (EPIC group = 67 patients). The survival, the recurrences and the sites of recurrence were assessed. Results. The 3-year survival rate for HIPEC group was 100% and for EPIC group 69% (P = .011). Nodal infiltration was found to be the single prognostic indicator of survival. The incidence of recurrence in EPIC group was higher than in HIPEC group (P = .009). The independent indicators of recurrence were the use of HIPEC and the degree of differentiation (P < .05). Conclusions. Intraperitoneal chemotherapy, particularly HIPEC, as an adjuvant in locally advanced colorectal carcinomas appears to improve survival and decrease the incidence of recurrence.

RESUMO

PURPOSE: The purpose of this study was to report the results of gastric cancer surgery in patients who had undergone potentially curative gastrectomy. METHODS: The hospital mortality, morbidity, survival, recurrences and the sites of failure were retrospectively analyzed in D1 group (conventional gastrectomy), and in D2 group (extended lymph node resection). RESULTS: D1 and D2 groups were comparable for age, gender, American Society of Anesthesiologists (ASA) class, type of surgery, and histopathologic characteristics (p>0.05). D2 group patients were in better physical status (p=0.008). The recurrence rate was higher in D1 group (p=0.019). Independent prognostic indicators of morbidity were male gender (p=0.012), and poor ASA class (p<0.001). Poor ASA class was the single independent prognostic indicator of hospital mortality (p=0.001). Ten-year survival for D1 and D2 was 44.1 and 64.8%, respectively (p=0.0433). D2 gastrectomy improved survival in stage IIIA. The independent prognostic indicators of survival were total gastrectomy (p=0.003), lymph node involvement (p<0.0001), and extended lymphadenectomy (p=0.003). The independent prognostic variables of recurrence were stage (p=0.001), and extended lymph node resection (p=0.006). CONCLUSION: D2 gastrectomy improves survival in gastric cancer, particularly in stage IIIA.

RESUMO

PURPOSE: Clinical, histopathological, and biological differences between right and left colon carcinomas have been questioned in the literature. The purpose of this retrospective study was to identify possible clinical and histopathological differences between the right and left colon carcinomas. METHODS: From 1987-2007, 109 patients with right colon carcinomas (RC group), and 186 patients with left colon carcinomas (LC group) were treated at a single institution. Clinical, histopathological, and biological variables were correlated to tumor location. The endpoint of the study was to see for any relationship between overall survival, recurrences, and their pattern in regard to tumor location. RESULTS: The incidence of distant metastases at initial diagnosis (p=0.049), and poorly differentiated tumors (p=0.001) was higher in right colon carcinomas. The 10-year survival rate in the RC group was 63% and in the LC group 66% (p >0.05). Recurrences, sites of recurrence, the in-hospital mortality and morbidity were similar in both groups (p >0.05). CONCLUSION: The biological behavior of right and left colon carcinomas is similar despite minor histopathological differences that do not influence survival and development of recurrences.

RESUMO

PURPOSE: The incidence of locoregional recurrence in rectal cancer has declined since total mesorectal excision (TME) has been widely adopted. The purpose of this study was to investigate the long-term survival and the incidence of locoregional recurrences in patients with middle and low rectal carcinomas undergoing TME. METHODS: The medical records of 126 patients with middle and low rectal carcinomas treated from 1987-2007 were retrospectively reviewed. Of them 80 had undergone total mesorectal excision (TME-group) and 46 surgery with conventional methods (CON-group). Clinical variables were correlated to morbidity, hospital mortality, recurrence, sites of recurrence, and survival. RESULTS: The groups were comparable except for type of surgery and sites of recurrence. Five-year overall survival rate for TME group was 75% and for CON-group 47% (p=0.0346). Although the groups were not different for the total number of recurrences, the number of locoregional recurrences was significantly lower in TME group (p=0.004). CONCLUSION: TME appears to improve long-term survival in patients with middle and low rectal carcinomas. The incidence of locoregional recurrence is also reduced by TME.

RESUMO

PURPOSE: To report our preliminary experience in the combined treatment of peritoneal carcinomatosis (PC) using cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (HIPEC). PATIENTS AND METHODS: This prospective study included patients with PC from gynaecological, gastric and colon cancer, treated in two centers. Cytoreductive surgery included the peritonectomy procedures described by Jacquet and Sugarbaker as well as multivisceral resections in order to achieve a complete macroscopical cancer eradication. The HIPEC that followed was performed via the open abdomen technique. RESULTS: Twenty-four patients (3 men and 21 women, mean age 60 years) were treated. Twelve patients had PC from ovarian cancer, 7 from colon, 3 from gastric and 2 from uterine cancer. The mean duration of the procedure was 7.83 h (range 5 -12.30). Macroscopically, complete cytoreduction (CC) was achieved in 18 (75%) patients. Two (8.3%) patients died in the first 30 days. The overall morbidity was 42% and 2 patients were reoperated. The mean follow up was 22 months (range 3-36). The overall 1-year survival was 59.1%; concerning the gynaecological cancers it was 53.8% (mean survival 11.7 months) and for gastrointestinal cancers it was 44.4% (mean survival 9.5 months). CONCLUSION: Our preliminary data suggest that the combined treatment of cytoreduction plus HIPEC for PC is associated with acceptable mortality and morbidity and offers an improved survival in these patients. An optimal patient selection and establishment of experienced centres are of paramount importance.

RESUMO

The impact of cytoreductive surgery with standard peritonectomy procedures has not been extensively assessed in the treatment of advanced ovarian cancer. The aims of the study are to report the long-term results of patients with advanced ovarian cancer undergoing cytoreductive surgery with standard peritonectomy procedures and to identify the prognostic indicators that may affect outcome. The records of 74 women with advanced ovarian cancer were retrospectively reviewed. Clinical indicators were correlated to survival. The hospital mortality and morbidity rates were 13.5% and 28.4%, respectively. Complete or near-complete cytoreduction was possible in 78.4% of the patients. Overall 10-year survival rate was 52.5%. Complete cytoreductive surgery, small-volume tumor, low-grade tumor, the absence of distant metastases, the use of systemic adjuvant chemotherapy, performance status >70%, and limited extent of peritoneal carcinomatosis were favorable indicators of survival. Complete cytoreduction (P= 0.000) and treatment with systemic chemotherapy (P= 0.001) independently influenced survival. Recurrence was recorded in 37.8% of the patients and was independently influenced by the tumor grade (P= 0.037). Cytoreductive surgery with standard peritonectomy procedures followed by adjuvant chemotherapy offers long-term survival in women with advanced ovarian cancer who have limited peritoneal carcinomatosis and no distant and irresectable metastases.

RESUMO

BACKGROUND/AIMS: Non-radical surgery is the preferred method of treatment of hydatid liver disease, and is associated with low mortality and recurrence rate. The purpose of the study is the retrospective analysis of the outcome of patients who were treated surgically in a single institution. MATERIAL AND METHODS: Between 1987 and 2005, 59 patients, mean age 58.2 +/- 15.9 (13-83) years, underwent surgery for liver hydatid disease. The patients were reassessed with physical examination, serological tests and radiological examination for the evaluation of the recurrence rate. RESULTS: Most cysts were solitary, the more frequently affecting the right lobe of the liver. Radical surgery was possible in four cases (6.8%) that were classified as PNM stage I. Partial cystectomy and omentoplasty was performed in 37 patients (62.7%) and external drainage with partial cystectomy in 18 patients (30.5%). The hospital morbidity was 27.2% and was found to be related to ASA class (p = 0.019). Hospital mortality was 5.1%. The median follow-up time was 94 (1-228) months and 45 out of 59 patients (76.3%) were reassessed, but no recurrence was recorded. There was no significant difference in morbidity, mortality, and hospital stay between partial cystectomy combined with external drainage or omentoplasty (p > 0.05). CONCLUSIONS: PNM staging seems to be a reliable tool in selecting patients with liver hydatid disease for non-radical or radical surgery. Omentoplasty is an easy and effective surgical method for the treatment of hepatic echinococcosis but is not different than partial cystectomy and external drainage in regard to morbidity, mortality, and recurrence.

RESUMO

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.

RESUMO

Colorectal carcinomas are predominantly spread malignancies. Peritoneal carcinomatosis frequently associates colorectal carcinomas. The tumour grade, the completeness of cytoreduction, the tumour volume, the presence of distant metastases, prior surgery score and the extent of peritoneal implantations are prognostic clinical features of survival. The management of colorectal cancer with peritoneal carcinomatosis is possible by resection of tumour, cytoreduction and intraperitoneal chemotherapy. T3 and T4 colorectal tumours are at risk of developing locoregional recurrence and may be treated by intraperitoneal chemotherapy. Early postoperative intraperitoneal chemotherapy has been used in 40 patients with T3 and T4 tumours, with 15% hospital mortality, and 32.5% morbidity. The overall 3-year survival rate was over 80% and only 15% distant metastases were recorded.

RESUMO

AIM: The peritoneal cancer index (PCI) has been used for the detailed evaluation of the peritoneal spread in tumors of gastrointestinal origin and has been found to be a prognostic indicator of survival. The aim of this study was the identification of the significance of the peritoneal cancer index in advanced ovarian cancer. METHODS: From 1990 to 2001, 60 women, mean age 65+/-10.84 (41-86), were treated for advanced ovarian cancer. The performance status (Karnofsky performance scale), age, prior surgery score (PSS), peritoneal cancer index (PCI), tumor volume, tumor grade, residual tumor, the presence of ascites, treatment with adjuvant chemotherapy, histopathologic subtype and FIGO stage were retrospectively correlated to survival using univariate model of statistical analysis. RESULTS: Hospital mortality and morbidity were 11.7 and 16.7% respectively. The recurrence rate was 23.3%. Overall 5-year survival rate was 41% and mean survival 63+/-8 months. The peritoneal cancer index was related to survival (P=0.0253). The other favorable clinical prognostic indicators of survival were low grade and small volume tumors, treatment with adjuvant chemotherapy and complete cytoreductive surgery (P<0.05). CONCLUSIONS: The peritoneal spread in advanced ovarian cancer can be assessed in detail using the peritoneal cancer index. It is a significant prognostic factor of survival and is useful in identifying subgroups.
