This paper reviews the reports from preclinical studies leading to the design of combined modality protocols and describes the effects produced when platinum complexes are combined with RT. Two interactions that are receiving considerable attention since they might produce an improved therapeutic ratio are the radiosensitization of hypoxic cells and post-RT potentiation of cell kill. This latter effect might include the inhibition of recovery from RT-induced potentially lethal or sublethal damage. However, platinum-radiation interactions are complex and probably include several mechanisms that are unknown at this time. The potential for platinum complexes will be especially promising if results of ongoing phase III combined modality trials show them to be efficacious, since it is unlikely that current protocol designs are optimal. Furthermore, second-generation platinum analogs or other metal complexes designed as potentiators of RT may prove to be more interactive with RT.</p>","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 6","pages":"315-9"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14479615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Used at a single ip dose of 50 or 60 mg/kg or at 5 daily doses of 10 mg/kg, SPG was ineffective in prolonging survival of rats burdened with the intracerebrally implanted tumor, i.e., the median survival time (MST) was the same as that for the controls. Only a schedule of 3 X 20 mg SPG/kg every other day improved the MST compared with controls. Single-dose (20-Gy) radiation therapy (RT, cesium-137 whole-head irradiation) did prolong survival. However, when single-dose SPG was combined with RT (1 hr or 1 day before, or 1 hr after RT), the survival response was worse than after RT alone. When the daily SPG was combined with daily RT (5 doses of 6 Gy), survival was no better than after daily RT alone. In vitro, SPG produces a concentration-dependent, exponential decrease in cell survival as measured by colony formation assay. When combined with radiation, there is an additive effect on cell lethality. Aside from the possibility that SPG does not penetrate the rat brain tumor itself, we have no explanation why SPG shows some activity against human brain tumors and is cytotoxic against 9L cells in vitro, yet is both ineffective by itself and fails to potentiate RT in the 9L rat brain tumor model.</p>","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 6","pages":"115-8"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14480247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five of these second cancers were acute nonlymphocytic leukemias (ANLL), and five were non-Hodgkin's lymphomas (NHL).

When appropriate adjuvant therapy (orchiectomy and/or radiation) is administered, residual cancer can be controlled locally for at least a limited period. The incidence of local progression in pathologic stage C or D1 disease may be negligible after early adjuvant orchiectomy and/or radiation treatment. The combination of immediate orchiectomy and radical prostatectomy has been shown to limit progression significantly (P = .0009) in many patients with D1 (T0-3 N1,2 M0) disease.

The DNA ploidy pattern may be a valuable predictor of disease outcome after treatment in stage D1 disease. Other pathologic variables (including acid phosphatase levels) have not been useful in predicting disease outcome or treatment response. Finally, patients with limited clinical stage C disease and those with pathologic C or D1 disease should be enrolled in a prospective randomized protocol so that the possible beneficial effects of adjuvant treatment programs can be evaluated.

Survival rates are promising in patients with negative pelvic lymph nodes and local tumors who undergo radical prostatectomy. In the presence of positive nodes, there is little reason to proceed with radical prostatectomy. Noninvasive alternatives to pelvic node dissection are appealing, but lymphangiography, ultrasound, computed tomography scanning, and magnetic resonance imaging are all less reliable than pelvic lymphadenectomy.

Pelvic lymph node dissection can play a role in treatment planning for patients who will be given external-beam radiation therapy. However, the role depends on the physician's treatment philosophy.
