[Show abstract][Hide abstract] ABSTRACT: Aim:
The pancreas is a preferred site of metastasis from renal cell carcinoma (RCC), that may occur even after many years from a radical nephrectomy. Surgical R0 resection remains the only potentially curative treatment for solitary tumor. The possibility of a multifocality of the lesions (20-45%) must be considered.
Material of study:
We report a case of metachronous pancreatic metastasis from RCC that occurred twice. After five years from a right polar inferior nephrectomy for a RCC, two nodular lesions were identified in the body-tail of the pancreas and were treated with distal pancreatectomy and splenectomy. After six months the CT imaging revealed a nodular lesion of few millimeters in the residual pancreatic body; we followed the slow growth and in October 2012, when the size reached 2 cm, the patient was operated to remove the residual portion of pancreatic body. After 16 months of follow-up the patient is well and there isn't relapse of disease.
Patients with metachronous pancreatic lesions represent a particular group with a more indolent course of RCC, the appearance of metastases after a prolonged interval from nephrectomy is related to a more favorable prognosis. Radical lymph-node dissection is not necessary for the uncommon involvement of peripancreatic nodes, condition that explains the positive outcomes achieved with surgery.
Patients with resected metastasis present an 88% survival rate at 5 years versus 47% observed in nonoperated patients; studies provide encouraging results in survival and quality of life of surgically treated patients.

[Show abstract][Hide abstract] ABSTRACT: Aim:
To assess the incidence of morbidity and mortality of Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy.
Patients and methods:
A retrospective multicentric study was performed. Six hundred and eighty-three patients were recorded. Predictors of morbidity and mortality were evaluated with univariate and multivariate analysis.
In univariate analysis, older age, Eastern Cooperative Oncology Group score, a greater value of Peritoneal Cancer Index (PCI) and sub-optimal cytoreduction were correlated with higher mortality, while older age, presence of ascites, ovarian origin of carcinomatosis, closed technique, a greater value of PCI, longer operative time and sub-optimal cytoreduction were predictors of higher morbidity. In multivariate analysis, older age and a greater value of PCI were correlated with higher mortality; older age, ovarian origin of tumor, presence of ascites, closed technique and longer operative time were predictors of higher morbidity.
Careful patient selection has to be performed to improve clinical outcomes.

[Show abstract][Hide abstract] ABSTRACT: Aim:
Intrathoracic extension in patients with pseudomixoma peritonei is a rare event, but spread of the tumour beyond the abdomen in to pleuropulmonary cavity has been reported.
Materials and methods:
We report a case of a 50-years-old woman with synchronous pleural manifestation of pseudomixoma peritonei by a mucinous ovarian cancer. During the abdominal cytoreductive surgery an extensive disease under the right hemidiaphragm was noted, requiring partial diaphragmatic resection. Once the pleural space was entered,mucinous neoplastic implants on the pleural surface was observed. The diaphragmatic defect was left open during the hyperthermic chemoperfusion to treat both the pleural and peritoneal surfaces. After a postoperative course uneventful she died after 6 months for a myocardial infarction, in presence of a left side pleural effusion with a positive cytology for high-grade malignant cells with a smear background contained wispy mucin.
Despite the aggressive spread of the pseudomixoma peritonei within the peritoneal cavity, lymphatic and hematogenous metastasis are rare. However, extension of disease into pleuropolmonary cavity has been well described as pleural effusion or pleuropulmonary metastases. This is the first report in literature, to our knowledge, in which the thoracic extension is due to a mucinous ovarian cancer, and is the second case in which a simultaneous bicavitary hyperthermic chemoperfusion was done as a management option for thoracic extension of pseudomixoma peritonei.
Due to the rarity of the thoracic involvement by pseudomixoma peritonei, its correct treatment is still unclear. Simultaneous cytoreductive surgery associated to intraoperative intraperitoneal and intrathoracic chemohyperthermia can be a potential therapeutic option for these patients.

[Show abstract][Hide abstract] ABSTRACT: Peritoneal carcinomatosis of gastric origin is associated with poor survival. The use of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) did not significantly improve the survival of patients with this disease. A promising approach can be based on the use of HIPEC as prophylaxis of peritoneal dissemination.
From our database, we have sampled 12 patients with advanced gastric cancer. In all cases, a D2 total gastrectomy was performed, associated with splenectomy in four cases. All patients were submitted to HIPEC.
Morbidity and mortality were 33.3% and 8.3%, respectively. The median survival was 24 months, with only one case (8.3%) of peritoneal recurrence.
In light of our experience and supported by literature data, we can affirm that HIPEC has a potential role in the prevention of gastric carcinomatosis. Certainly further studies are required on a larger scale to validate this new but promising approach.

[Show abstract][Hide abstract] ABSTRACT: Paragangliomas are neural crest-derived neuroendocrine tumors, originating from paraganglia, which are dispersed neuroendocrine organs characterized by catecholamine and peptide-producing cells. With an annual incidence estimated at 1/100,000, paragangliomas represent 10% of catecholamine secreting tumors.
We report a case of a 76-year-old man who was submitted to a subtotal gastrectomy with omentectomy and gastrojejunal anastomosis. The Hystologic exam has revealed an ulcerative polypoid gastric carcinoma with cell poorly cohesive and infiltration of the muscular gastric wall and an incidental parietal gastric lesion which was a paraganglioma with immunocytochemical investigations positive for NSE and negative for CD117, S100, CD34 e SMA.
Pheochromocytoma indicates exclusively tumors arising from the adrenal medulla, while the extra-adrenal paraganglioma suggests tumors of the chromaffin cells with other locations. Gastric or paragastric localization, as in our case, is very rare for these neoplasms, and in literature there are only isolated case reports. Genetical predisposition is observed in 30% of these tumors and can be responsible of hereditary disease characterized for differences in tumor distribution, catecholamine production, risk of metastasis, and association with others types of tumors.
In asymptomatic patients and when biochemical and clinical suspicion of neuroendocrine tumor is strong, you have to perform anatomical and functional investigations to detect these neoplasms. The first line treatment for resectable tumors is complete surgical resection, that can be performed with open surgery or laparoscopic technique. Surgical therapy is also indicated to palliative intent when a complete eradication of disease is not achievable for metastatic status of malignancies.

[Show abstract][Hide abstract] ABSTRACT: Metastatic lesions of the gallbladder are an infrequent clinical condition. The metastatic lesions of gallbladder from primary breast tumors are rarely described in literature.
We report a case of an 83-year-old woman who underwent cholecystectomy for cholelithiasis by video laparoscopy (VL), and in whom a metastatic lesion was detected at the histological examination of surgical specimen. For this reason, the patient was subjected to diagnostic-instrumental investigation with the aim of detecting the primary tumor, which showed the presence of infiltrating lobular carcinoma, pleomorphic variety, in the upper outer quadrant of the right breast.
Breast cancer and in particular the histological type "ductal infiltrating" is frequently associated with locoregional and distant metastases, the latter especially to bones, liver, lungs and central nervous system. An analysis of literature was conducted on secondary lesions of the gallbladder from breast cancer that has allowed us to confirm the rarity of this disease only described in 18 patients: 12 from infiltrating lobular, 1 ductal origin and 2 mixed ductal and lobular infiltrating.
The most frequent tumor histology associated with the above-mentioned metastatic localization is the metastatic infiltrating lobular carcinoma. Clinically speaking, it is difficult to suspect a metastatic localization from primary breast cancer in the gallbladder, but it is necessary to be well aware of the possibility of metastasis and to bear this in mind during the follow-up of patients with breast cancer. Although cholecystectomy is regarded as a palliative treatment in patients with metastasis in the gallbladder from breast cancer, it is intead recommended in symptomatic cases.

[Show abstract][Hide abstract] ABSTRACT: The creation of a stoma, although considered a simple surgical procedure, is burdened by various complications, one of the most common being prolapse. Usually prolapse increases gradually, involving generally limited functional disorders and it can be well managed with non-operative measures. Occasionally it requires major surgery, for severe skin excoriation, bleeding or incarceration of the bowel. However, for critical clinical conditions of patients, often is not possible to use classical techniques, as bowel-pexy fixation or resection of the prolapse. Maeda has described a simple method for the correction of prolapse of the transverse colon using a stapler device that can be applied in this type of patients. In this report, we describe the first application of this technique to treat the prolapse of the ileocecal loop in an 81-year old woman, suffering from Parkinson's disease. A definitive ciecum stoma was performed the previous year for an Olgivie syndrome. At 6 months, follow-up showed no recurrence of prolapse with a functional stoma and without any skin irritation. In conclusion, this approach is recommended especially for high-risk patients who cannot be submitted to a much more invasive treatment. In fact, the main advantages consist of a minimally invasive technique, with minimal blood loss and with a rapid recovery of a normal quality of life.
[Show abstract][Hide abstract] ABSTRACT: Nowadays the standard clinical management for advanced epithelial ovarian cancer is constituted by primary cytoreductive surgery associated to adjuvant systemic chemotherapy. Even if this first-line chemotherapy shows a high rate of complete responses, the disease recurrences occur especially in stage-III patients. Actually an option for this subset of patients is represented by secondary cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy that represents a promising therapy, having shown positive results in terms of median overall survival, progression free survival and overall survival. However, a much more research is still required especially by prospective randomised trials to improve outcomes in recurrent ovarian cancer.
[Show abstract][Hide abstract] ABSTRACT: To assess the efficacy and morbidity and mortality of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in recurrent epithelial ovarian cancer (EOC).
A retrospective study conducted using information extracted from a multi-institutional prospective database on peritoneal surface malignancies (PSMs). Setting Four Italian centres specializing in locoregional treatment of PSM.
Patients with recurrent EOC.
Fifty-six patients underwent 57 combined procedures. CRS was performed using peritonectomy procedures and HIPEC using the closed-abdomen technique with cisplatin and doxorubicin or cisplatin and mitomycin-C.
Overall survival (OS), progression-free survival (PFS), morbidity and mortality rates.
The median age of the patients was 55.2 years (range 30-75 years). The median peritoneal cancer index was 15.2 (range 4-30). Forty-seven patients had microscopic residual disease (completeness of cytoreduction, CC-0), seven had residual disease ≤2.5 mm (CC-1) and one had residual disease >2.5 mm (CC>2). Major complications occurred in 15 patients (26.3%), and procedure-related mortality occurred in three patients (5.3%). The median follow-up time was 23.1 months. The median OS and PFS were 25.7 (95% CI 20.3-31.0) and 10.8 (95% CI 5.4-16.2) months, respectively. The 5-year OS and PFS were 23% and 7%, respectively. Independent prognostic factors affecting OS according to the multivariate analysis were Eastern Cooperative Oncology Group performance status, preoperative serum albumin, and completeness of cytoreduction.
Patients with recurrent EOC treated with CRS and HIPEC showed promising results in terms of outcome. The combined treatment strategy could benefit subsets of patients wider than that defined for conventional secondary debulking surgery without HIPEC. These data warrant further evaluation in randomised clinical trials.

[Show abstract][Hide abstract] ABSTRACT: To evaluate the role of the hepatic perfusion in the assessment of the colorectal cancer.
For this research 18 patients affected by colorectal cancer were enrolled. All the patients were submitted to the evaluation of the Doppler Perfusion Index (DPI) which represents the ratio of hepatic arterial to total liver blood flow.
The correlation between the evaluation of the Doppler Perfusion Index and the occurrence of the liver metastases did not show false negative but has highlighted 6 false positive, achieved a good sensitivity and very low specificity.
A review of the literature and the results obtained in our study suggest that DPI may be helpful in detection of hepatic metastases.
[Show abstract][Hide abstract] ABSTRACT: The evolution of loco-regional treatments has occurred in the last two decades and has deeply changed the natural history of primitive and secondary peritoneal surface malignancies. Several phase II-III studies have proved the effectiveness of the combination of cytoreductive surgery with peritoneal chemohyperthermia. Cytoreductive surgery allows the reduction of the neoplastic mass and increases tumoral chemosensitivity. The development of chemohyperthermia finds its origins in the necessity to exceed the limits of intraperitoneal chemotherapy performed in normothermia. It permits a continuous high concentration gradient of chemotherapeutic drugs between the peritoneal cavity and the plasma compartment to and a more uniform distribution throughout the abdominal cavity compared to systemic administration.
[Show abstract][Hide abstract] ABSTRACT: The treatment of peritoneal malignancies in elderly patients with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is an ongoing question due to the high associated surgical risk.
Thirty patients, 11 (36.7%) older than 65 years, were submitted to CRS plus HIPEC. Criteria of patient eligibility were: peritoneal carcinomatosis of different origin, T3-4 gastric cancer, ECOG performance status ≤2, no extra-abdominal extension and no evidence of bowel obstruction. The median follow-up was 21.5 months (range: 1-63). The purpose of this retrospective study, was to evaluate the feasibility of this approach in elderly patients, with special reference to postoperative morbidity, mortality and survival.
We have recorded, in elderly patients, higher grade 3 and 4 morbidity and mortality, similar mean duration of cytoreductive surgery, of postoperative hospital stay, of median survival and of overall survival rates.
Since there no statistical differences, in terms of morbidity and mortality, CRS with HIPEC may also be suitable for elderly patients.

[Show abstract][Hide abstract] ABSTRACT: The primary end-point of this multi-institutional phase-II trial was to assess results in terms of overall survival after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in treatment-naive epithelial ovarian cancer (EOC) with advanced peritoneal involvement. Secondary end-points were treatment morbi-mortality and outcome effects of time to subsequent adjuvant systemic chemotherapy (TTC).
Twenty-six women with stage III-IV EOC were prospectively enrolled in 4 Italian centers to undergo CRS and closed-abdomen HIPEC with cisplatin and doxorubicin. Then they received systemic chemotherapy with carboplatin (AUC 6) and paclitaxel (175 mg/m(2)) for 6 cycles.
Macroscopically complete cytoreduction was achieved in 15 patients; only minimal residual disease (≤2.5 mm) remained in 11. Major complications occurred in four patients and postoperative death in one. After a median follow-up of 25 months, 5-year overall survival was 60.7% and 5-year progression-free survival 15.2% (median 30 months). Excluding operative death, all the patients underwent systemic chemotherapy at a median of 46 days from combined treatment (range: 29-75). The median number of cycles per patient was 6 (range: 1-8). The time to chemotherapy did not affect the OS or PFS.
In selected patients with advanced stage EOC, upfront CRS and HIPEC provided promising results in terms of outcome. Morbidity was comparable to aggressive cytoreduction without HIPEC. Postoperative recovery delayed the initiation of adjuvant systemic chemotherapy but not sufficiently to impact negatively on survival. These data warrant further evaluation in a randomized clinical trial.
[Show abstract][Hide abstract] ABSTRACT: Acute pancreatitis is an inflammatory condition that may lead to multisystemic organ failure. Melanocortin peptides have been successfully used in experimental models of organ failure and shock, and their protective effect occurs through the activation of a vagus nerve-mediated cholinergic anti-inflammatory pathway by acting at brain melanocortin 4 receptors. In the light of these observations, we studied the effects of the selective melanocortin 4 receptor agonist RO27-3225 in an experimental model of cerulein-induced pancreatitis.
Research laboratory at a university hospital.
Experimental pancreatitis in rats.
Acute pancreatitis was induced in male Sprague-Dawley rats by intraperitoneal injections of cerulein (80 μg/kg, four injections at hourly intervals). Before pancreatitis induction, groups of animals were subjected to bilateral cervical vagotomy, pretreated with the nicotinic acetylcholine receptor antagonist chlorisondamine or the selective melanocortin 4 receptor antagonist HS024, or not pretreated. Thirty minutes after the first cerulein injection, rats were intraperitoneally treated with a nanomolar dose of RO27-3225 or vehicle. Some experimental groups were prepared for neural efferent activity recording along the vagus nerve starting 30 mins after treatment with RO27-3225 or vehicle, and for a 30-min period.
Serum lipase and amylase activity, tumor necrosis factor-α and interleukin-6 expression, pancreatic myeloperoxidase activity, and histologic damage were evaluated; neural efferent activity of vagal fibers was also assessed. RO27-3225 reduced cerulein-induced serum lipase and amylase activity, blunted the expression of tumor necrosis factor-α and interleukin-6, abated the increase in pancreatic myeloperoxidase activity, and protected against histologic damage. Furthermore, RO27-3225 markedly increased neural efferent activity along the vagus nerve. Vagotomy, chlorisondamine, and HS024 abated these protective effects of RO27-3225.
Our data show that melanocortin 4 receptor agonists reduce pancreatitis severity through the activation of the cholinergic anti-inflammatory pathway. These findings could be of particular interest in the clinical setting.

[Show abstract][Hide abstract] ABSTRACT: Favorable oncological outcomes have been reported in several trials with the introduction of Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in the treatment of Advanced Epithelial Ovarian Cancer (EOC). However most of the studies testing the combined approach are observational and have been conducted in inhomogeneous series so that the evidence supporting the performance of this combined treatment is still poor. Median Overall and Disease Free Survivals of up to 64 months and 57 months, respectively have been reported. Although a rate of morbidity of up to 40% has been observed in some series the CRS + HIPEC continues to gain an increased popularity. Several prospective randomized trials are ongoing using the procedure in various time points of the disease. In this review several issues such as the impact of cytoreduction and residual disease (RD) on outcomes as well as the role of HIPEC will be updated from the literature evidence. Some controversial points HIPEC related will also be discussed. Recent experiences regarding the introduction of a more aggressive surgical approach to upper abdomen to resect peritoneal carcinomatosis (PC) allowed increased rates of optimal cytoreduction and has demonstrated an apparent better outcome. This evidence associated with the positive results phase III trial testing normothermic intraperitoneal as first-line chemotherapy is guiding some investigators to propose the CRS + HIPEC in the primary setting. Several prospective phase II and III trials have recently been launched to validate the role of the combined treatment in various time points of disease natural evolution.
