Subsequent to the recognition of the intraperitoneal tumors of low malignant potential, clinicians have repeatedly faced the ambiguities inherent in a disease that seems aggressive on the basis of its wide distribution in the peritoneal cavity but benign on the basis of its histopathology and clinical course. Whereas the occasional case has been associated with extensive local reaction and ascites, except for a rare exception these tumors result in prolonged survival and in an absence of extraabdominal extension. The current review of 154 cases followed from 2 to 40 years, performed in an attempt to understand this perplexing disease, leads to the following conclusions: 1) Whereas frequently beginning on the ovary and showing a predilection for the pelvis, there are examples of widely disseminated peritoneal disease with minimal, if any, ovarian involvement; 2) the outcome without adjunctive therapy is excellent and thus such therapy is contraindicated in view of the death of only 2 of the 154 patients with disease, 1 of whom had had adjunctive intraperitoneal isotope therapy; and 3) this disease is best understood as a diffuse primary peritoneal tumor probably developing on the basis of irritating agents' reaching the abdominal cavity from the lower genital canal, a process similar to that proposed for the genesis of endometriosis. Such a low-grade primary in situ tumor that may involve the entire peritoneal cavity is compatible with prolonged survival.
[Show abstract][Hide abstract] ABSTRACT: Borderline ovarian tumors have an excellent prognosis. In stage I disease, no therapy in addition to surgery is needed, and conservation of ovarian tissue for future childbearing may be appropriate. In advanced stages, the use of adjuvant therapy has not consistently led to cures, and complications have been reported. A randomized study of no adjuvant therapy versus adjuvant treatment with long-term follow-up will be necessary to determine the efficacy of additional treatment.

[Show abstract][Hide abstract] ABSTRACT: A brief description is given of techniques that have proved successful in obtaining samples of hot and cold spring waters for x-ray fluorescence, neutron activation, and radiometric analysis. The sampling methods require only lightweight, portable field apparatus. Various types of springs sampled are illustrated. Chemical geothermometer temperatures from these samples have compared well with reported measured subsurface temperatures. (LBS)
[Show abstract][Hide abstract] ABSTRACT: The prognostic significance of periodic acid-Schiff (PAS) stain in 112 serous: 43 benign, 25 borderline and 44 malignant cystadenomas: and in 106 mucinous: 60 benign, 32 borderline and 14 malignant cystadenomas of the ovary were investigated. The amount of positively stained mucin was estimated morphometrically. The outcome of most patients with benign or borderline lesion was good. One patient with benign mucinous cystadenoma died, however, of pseudomyxoma peritonei and another patient with borderline mucinous cystadenoma died of peritoneal carcinosis. Other patients were alive and free of the disease after a follow-up of 1-14 years, or had died of causes unrelated to the ovarian disease. Abundant PAS positive mucin predicted a longer survival both in serous and in mucinous malignant tumors. The 5-year survivals for the serous cystadenocarcinomas with and without PAS positive mucin were 21% and 13%, respectively (not statistically significant). For mucinous cystadenocarcinomas with mucin value over and below the median, the 5-year survival rates were 57% and 14%, respectively (P less than 0.10). High PAS positivity in both serous and mucinous cystadenocarcinomas clearly indicated better prognosis, although statistical significance was not achieved. Thus, further studies are needed for final evaluation of the prognostic significance of the PAS stain in these ovarian tumors.
