However, all treated cell lines express resistance to vincristine and, with one exception, to VP-16-213. Preliminary evidence has indicated that resistance to vincristine in drug-treated cells, but not x-irradiation-treated cells, is associated with impaired vincristine uptake; resistance to VP-16-213 in both differently derived, resistant sublines is associated with a reduction of VP-16-213-induced DNA single-strand breakage; and collateral sensitivity to cisplatin in x-irradiation-treated cells is associated with enhanced drug-induced DNA cross-linking. These data indicate that patterns of responses to antitumor drugs and the mechanisms associated with these altered responses differ depending upon the agent used to induce resistance.","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 6","pages":"177-81"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14480709","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}

There was no improvement in survival compared to that in the group treated with chemotherapy alone. In our present pilot study, we are investigating the toxicity and efficacy of using hemibody irradiation (HBI) as a non-cross-resistant agent early in a program of alternating chemotherapy consisting of six treatment cycles. Toxicity due to the combined effects of chemotherapy (cisplatin and etoposide plus cyclophosphamide, doxorubicin, and vincristine) plus HBI is reported. The HBI was given at a dose of 1,000 cGy in four fractions for limited disease or as a single 800-cGy dose for extensive disease. Bone marrow suppression following HBI necessitated a subsequent delay in the chemotherapy cycle or dose reduction in 55% of the 33 patients. Six patients developed diffuse interstitial pneumonitis following chemotherapy and HBI; 3 have died, and in 2 of these, the etiology was opportunistic infection. In our previous studies utilizing HBI either alone or as consolidation therapy after induction chemotherapy, a low incidence of lung toxicity occurred. This increased incidence suggests a possible drug-radiation interaction when HBI is used as an alternating agent with doxorubicin and cisplatin.","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 6","pages":"271-4"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13970431","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}

Sixty-four patients having stage III disease without distant metastases were treated with 4 cycles of combined chemotherapy and radiation to 40 Gy and were offered surgical resection. Thirty-nine patients (61%) underwent surgery. Nine had no residual cancer. No correlation was noted between clinical and histologic responses in the surgery group, but histologic response correlated with subsequent outcome. Survival was 58% at 1 year, 33% at 2 years, and 22% at 3 years.

{"title":"Radical retropubic prostatectomy with reduced morbidity: an anatomic approach.","authors":"P C Walsh","doi":"","DOIUrl":"","url":null,"abstract":"The morbidity of radical retropubic prostatectomy for prostate cancer has been reduced through improved understanding of the surgical anatomy of the prostate. Delineation of the anatomy of the dorsal vein complex has led to modifications in the surgical technique that have reduced blood loss and improved surgical exposure. The addition of epidural anesthesia and presurgical donation of autologous blood has limited the need for the homologous transfusion of blood to 2% of the patients and has reduced the frequency of serious perioperative complications such as pulmonary emboli to 0.3%. Delineation of the anatomy of the pelvic plexus and identification of the neurovascular bundles as the macroscopic landmark of the microscopic cavernous nerves have made it possible for the surgeon to make an informed decision at the time of surgery whether the neurovascular bundles can be preserved safely or excised widely with the specimen. In all surgical approaches to prostate cancer, the primary goal must be excision of all tumor; preservation of sexual function should be of secondary concern. These considerations were addressed in the treatment of 320 consecutive patients; 74% of the men are potent postoperatively. It was necessary to excise one neurovascular bundle widely in 49 patients; 69% are potent. In addition to improvements in postoperative sexual function, the incidence of incontinence following surgery has been reduced. The total medical expenses for patients undergoing radical prostatectomy range from $8,500 to $9,500 and are similar to those for external-beam radiotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 7","pages":"133-7"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14304894","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}

{"title":"Pilot study of interaction of radiation therapy with doxorubicin by continuous infusion.","authors":"C J Rosenthal, M Rotman","doi":"","DOIUrl":"","url":null,"abstract":"Doxorubicin was initially administered alone by continuous infusion for 5 days every 3 weeks in escalating doses to 13 patients with advanced metastatic and/or recurrent malignancies. The maximum tolerable dosage was 13 mg/m2 per day for 5 days. Kinetic data showed a steady level of 60 ng/ml for 4 days and a biphasic disappearance curve. Radiation therapy (150-200 cGy per session) was then administered in 5-day cycles, every 3 weeks, concomitantly with continuous infusion of doxorubicin (12 mg/m2 per day) to 21 patients with various advanced unresectable recurrent or metastatic malignancies. Four of 9 patients with soft tissue sarcomas achieved complete response after a radiation dose of 2,206 +/- 590 (SD) cGy and 3 had partial response; the median durations of the response were 142 +/- 65 (SD) weeks for complete response and 28 +/- 10 weeks for partial response. Of 4 patients with primary hepatoma, 2 achieved partial response after 1,290 +/- 210 cGy. No response was seen in any of the 7 patients with adenocarcinoma of the gastrointestinal tract or breast. Complications of this regimen included moderate leukopenia and thrombocytopenia, mucositis, skin erythema, and decrease of the ventricular ejection fraction at a cumulative doxorubicin dose of 840 mg/m2. We conclude that doxorubicin given by protracted infusion can be safely administered with concomitant radiation and appears to enhance the effects of radiation on most soft tissue sarcomas and on some hepatocellular carcinomas.","PeriodicalId":77576,"journal":{"name":"NCI monographs : a publication of the National Cancer Institute","volume":" 6","pages":"285-90"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14479611","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}
