[Multiple primary neoplasms - coincidence or tumor syndrom?]

Praxis — Tue, 08 Sep 2009 23:00:00 +0100

We present the history of an actually asymptomatic female patient with four different malignancies within 30 years: malignant melanoma (1976), liposarcoma (1983), carcinoma of the appendix (2006) and lymphoma (2006). Discussion: There is not only a remarkable variety of malignant tumors but also an extraordinary long survival without recurrence of the generalised malignomas of the skin and soft tissue (malignant melanoma and liposarcoma). It is difficult to explain the entire restitution with the implemented treatments (several tumor resections, chemotherapy with Ifosfamide). More than 20 years after chemotherapy, the lymphoma can be classified as a secondary malignoma. We discuss the pathogenesis of multiple malignomas in further details.

Incidence, Risk Factors, and Impact of Severe Neutropenia After Hyperthermic Intraperitoneal Mitomycin C

Annals of Surgical Oncology — Thu, 28 May 2009 09:13:10 +0100

Conclusion Neutropenia is a frequent complication associated with MMC-HIPEC. Female sex and MMC dose per BSA are independent risk factors for neutropenia. These differences must be considered in the management of patients undergoing MMC-HIPEC to minimize the toxicity of the procedure.

Epithelial Appendiceal Neoplasms.

Cancer Journal — Thu, 30 Apr 2009 23:00:00 +0100

Authors: Sugarbaker PH The appendiceal malignancies usually arise within a mucocele. The tumor within this structure can be minimally aggressive or of an invasive character. If a low-grade appendiceal malignancy is removed intact, recurrence does not occur. If rupture of the wall of the mucocele occurs with either low-grade or high-grade disease, the epithelial cells within will disseminate to the peritoneal surfaces. Sometimes a second-look surgery must be performed to determine if intraperitoneal spread of mucus and cancer cells has occurred. If the diagnosis of peritoneal dissemination of an appendiceal malignancy has been established, a new treatment with curative intent is indicated. Cytoreductive surgery is combined with perioperative intraperitoneal chemotherapy as a comprehensi...

The Current Role of Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Dissemination of Appendiceal Tumors

Current Problems in Cancer — Thu, 30 Apr 2009 23:00:00 +0100

Appendiceal malignancies are rare with an age-adjusted incidence of about 0.12 cases per 1 million individuals per year. Appendiceal tumors are infrequently diagnosed before surgery and often present with peritoneal dissemination. In cases with low-grade cytology, this peritoneal dissemination is hypothesized to arise from perforation of the appendiceal tumor and subsequent dissemination of mucous-producing adenomatous epithelial cells throughout the abdomen and pelvis. This may lead to mucinous ascites or pseudomyxoma peritonei (PMP). In cases with high-grade cytology, the peritoneal dissemination is usually seen in association with an invasive mucinous carcinoma of the appendix. (Source: Current Problems in Cancer)

Signet ring cell carcinoma of the appendix manifesting as colonic obstruction and ovarian tumors: Report of a case

Surgery Today — Thu, 12 Mar 2009 10:24:48 +0100

We report a case of appendiceal adenocarcinoma manifesting as a colonic obstruction with a lower abdominal mass. Laparotomy revealed bilateral ovarian tumors and a small appendiceal tumor with peritoneal metastases. We performed ileocecal resection, colectomy, and oophorectomy, following which a histological diagnosis of signet ring cell carcinoma was made. Immunohistochemical analysis revealed positive expression of cytokeratin 7 and 20, and mucin core protein 2 (MUC2), compatible with appendiceal cancer and Kruckenberg metastases. When a patient is found to have disseminated pelvic signet ring cell carcinoma of unknown origin, the appendix should be considered as a possible primary site.

Peritoneal carcinomatosis: patients selection, perioperative complications and quality of life related to cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

World Journal of Surgical Oncology — Thu, 08 Jan 2009 05:00:00 +0100

Conclusions: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) provide a promising combined treatment strategy for selected patients with peritoneal carcinomatosis that can improve patient survival and quality of life. The extent of intraperitoneal tumor dissemination and the completeness of cytoreduction are the leading predictors of postoperative patient outcome. Thus, consistent preoperative diagnostics and patient selection are crucial to obtain a complete macroscopic cytoreduction (CCR-0/1). (Source: World Journal of Surgical Oncology)

Adenocarcinoma of the Appendix Is Rarely Detected by Colonoscopy

Journal of Gastrointestinal Surgery — Wed, 17 Dec 2008 09:29:16 +0100

Conclusions Appendiceal abnormalities are infrequently seen on colonoscopy and rarely yield a diagnostic biopsy in patients with appendiceal carcinoma. We found that nearly 42% of patients with carcinoma of the appendix have synchronous colonic polyps, a much higher prevalence than would be expected, supporting a role for a perioperative colonoscopy.

Treatment of appendiceal adenocarcinoma in the United States: penetration and outcomes of current guidelines.

The American Surgeon — Sat, 01 Nov 2008 04:00:00 +0100

This study evaluates appendiceal cancer outcomes in the United States and treatment guideline compliance. Data for patients diagnosed with appendiceal adenocarcinoma in the Surveillance, Epidemiology, and End Results database (1988 to 2003) were analyzed. The 2511 patients with appendiceal adenocarcinoma had an average age of 59.3 years, average tumor size of 4.05 cm, and 5-year survival rate of 57 per cent. The 5-year survival rate by stage was statistically different (P < 0.001): Stage 0, 95.7 per cent; Stage I, 88 per cent; Stage II, 75.2 per cent; Stage III, 37.1 per cent; and Stage IV, 25.6 per cent. Appendectomy was performed in 33.4 per cent, which does not follow the current guidelines. In this group, 5-year survival was significantly less for patients with Stage III and IV dise...

Primary signet ring cell carcinoma of the appendix: A rare case report and our 18-year experience.

World Journal of Gastroenterology : WJG — Tue, 07 Oct 2008 04:00:00 +0100

Authors: Ko YH, Jung CK, Oh SN, Kim TH, Won HS, Kang JH, Kim HJ, Kang WK, Oh ST, Hong YS Primary adenocarcinoma of the appendix is a rare malignancy that constitutes < 0.5% of all gastrointestinal neoplasms. Moreover, primary signet ring cell carcinoma of the appendix is an exceedingly rare entity. We have encountered 15 cases of primary appendiceal cancer among 3389 patients who underwent appendectomy over the past 18 years. In the present report, we describe a rare case of primary signet ring cell carcinoma of the appendix with ovarian metastases and unresectable peritoneal dissemination occurring in a 67-year-old female patient. She underwent appendectomy and bilateral salpingo-oophorectomy with a laparoscopy procedure. She then received palliative systemic chemotherapy with 12 c...

[Treatment of peritoneal carcinomatosis with surgery and hyperthermic peroperative intraperitoneal chemotherapy (HIPEC): new aspects and validated indications]

Bulletin du Cancer — Tue, 01 Jan 2008 05:00:00 +0100

Authors: Eveno C, Dagois S, Guillot E, Gornet JM, Pocard M Hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) is now an entire part of treatment of peritoneal dissemination of colorectal malignancy, and it's possible to hope prolonged survival. This treatment is more and more codified. Four indications are recognized by some tree national evaluation committees: the French ANAES, the British NICE and the Canadian CEPO: colorectal carcinoma, carcinoma of the appendix, pseudomyxoma peritonei and mesothelioma. Last big published series results show a decrease of morbidity and mortality and interest of using new drugs like oxaliplatine. Indications have to be more homogeneous and based on evidences.

Perioperative intraperitoneal chemotherapy for peritoneal surface malignancy

Journal of Translational Medicine — Mon, 10 Apr 2006 06:00:00 +0100

The treatment of peritoneal surface malignancy mainly focuses on diffuse malignant peritoneal mesothelioma, pseudomyxoma peritonei from appendiceal cancer, and peritoneal dissemination from gastrointestinal and ovarian cancers. Cancer progression causes peritoneal implants to be distributed throughout the abdominopelvic cavity. These nodules plus the ascitic fluid result in abdominal distension. As the disease progresses, these tumors cause intestinal obstruction leading to debilitating symptoms and a greatly impaired quality of life. In the past, the prognosis of patients with peritoneal surface malignancy was regarded dismal and cure was not an option. Recently, cytoreductive surgery combined with perioperative intraperitoneal chemotherapy has shown an improved survival in selected patie...
