Pseudomyxoma peritonei of appendiceal origin. The Memorial Sloan-Kettering Cancer Center experience.

BACKGROUND: Pseudomyxoma peritonei is a rare clinical entity in which the peritoneal surfaces and omentum are involved with diffuse gelatinous mucinous implants. It originates from ruptured mucinous tumors of the appendix or ovary. METHODS: The authors examined the experience with 34 patients with pseudomyxoma peritonei seen at Memorial Sloan-Kettering Cancer Center from 1952-1989. Of these, 17 cases were identified to be of appendiceal origin. RESULTS: All patients underwent celiotomy and cytoreduction. The median survival time from diagnosis was 75 months. It was found that long-term survival can be achieved by operation alone. When conditions do recur, chemotherapy may be valuable. CONCLUSIONS: Pseudomyxoma peritonei of appendiceal origin is a rare low-grade malignancy. Initial treatment consists of cytoreduction in an attempt to render the patient locally disease-free. Long-term survival can be obtained by operation alone, even if gross disease is present at the end of the procedure. Systemic chemotherapy should be reserved for patients with proven recurrence.

Chemotherapy for nonmetastatic osteogenic sarcoma: the Memorial Sloan-Kettering experience.

PURPOSE: Adjuvant chemotherapy improves disease-free survival (DFS) for patients with osteogenic sarcoma (OS). We reviewed our experience with OS to determine prognostic factors, the role of preoperative chemotherapy and subsequent histologic response, and the role of salvage chemotherapy after poor initial response. METHODS: From 1975 to 1984, we saw 279 patients with previously untreated OS without metastasis. All patients received intensive chemotherapy and underwent surgical resection of primary tumor. Chemotherapy included high-dose methotrexate; Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH); and bleomycin, cyclophosphamide, and dactinomycin (BCD). Selected patients also received cisplatin. RESULTS: DFS was not affected by use of preoperative chemotherapy versus immediate surgery, by use of limb-sparing surgery versus amputation, age, sex, or dose intensity of chemotherapy. DFS did correlate with serum lactate dehydrogenase (LDH), alkaline phosphatase, primary tumor site, race, and histologic response to preoperative chemotherapy. There was no difference in DFS for patients with a poor histologic response who did or did not receive cisplatin, although patients who did receive cisplatin had a longer time to relapse. The 5-year DFS was 76% for patients aged less than or equal to 21 years who had extremity primary tumor and were treated with the T10 protocol. CONCLUSIONS: Intensive chemotherapy can achieve DFS for a high proportion of patients with OS. Although it is a powerful predictor of DFS, histologic response to preoperative chemotherapy cannot be assessed at diagnosis. We have not shown an ability to salvage patients with an unfavorable response. We need to increase the proportion of patients with a favorable response, identify the patients who will have an unfavorable response, and develop novel treatments to salvage poor responders.

Case report 671: Arteriovenous malformation of the right lower extremity with associated intraosseous hemangiomatosis.

Since extensive involvement of the lower extremity with arteriovenous malformations occurs often combined with the potential risk of hemorrhage, transcatheter embolization has become an attractive alternative to surgical resection [7, 9]. We describe an unusual case of extensive intraosseous hemangiomatosis, with a concomitant arteriovenous malformation that presented in a 35-year-old woman as synovitis in a knee. MR images demonstrated that the lesion was far more extensive than originally suggested and directed the subsequent biopsy and embolization. The differential diagnosis was discussed and the subject of intraosseous hemangiomatosis with associated AVM was considered in some detail.

Radiation-induced soft-tissue and bone sarcoma.

From the records of Memorial Hospital of the past 50 years, 47 cases with an established diagnosis of radiation-induced sarcoma were identified and divided into two groups: the first included 20 cases of soft-tissue sarcoma arising from irradiated tissues, and the second comprised 27 cases of bone sarcoma arising from normal bones in the irradiated field. Medians for the latent periods from irradiation to diagnosis of bone and soft-tissue sarcoma were 11 and 12, years, respectively. In bone sarcomas, the latent period was longer after larger radiation doses and children appeared to be more susceptible to cancer induction than adults. Criteria for establishing the diagnosis of radiation-induced sarcoma and the magnitude of the risk of bone sarcoma are discussed.

Esthesioneuroblastoma: is there a role for elective neck treatment?

A retrospective review of the Memorial Sloan Kettering Cancer Center experience (MSKCC) with esthesioneuroblastoma was performed. From 1975 to 1985 14 cases were identified. Overall 5- and 10-year survival was 86% and 70%, respectively. Four local failures were observed and 4 neck failures were observed. A review of the literature since 1966 revealed an unexpectedly high incidence of neck failure, and of the 21 of 110 patients with neck failures that were identified through the literature, there were 6 subsequent deaths.
