The results of radiotherapy alone for patients with locally advanced (stage III or IV) nasopharyngeal cancer (NPC) are poor in spite of the initial complete clearance. Twenty-seven patients (26 stage IV) were treated with concurrent standard radiotherapy and cisplatin 100 mg/m2 intravenously on day 1 and every 3 weeks for three courses. In 24 (89%) patients, complete response (CR) was achieved. The CR rate was higher for poorly undifferentiated cancer (100%). The major side effects were leukopenia (97%), anemia (54%), nausea and vomiting (81%), stomatitis (92%), and renal impairment (52%). Most of these side effects were either mild or moderate and reversible. All patients finished the radiotherapy dose (greater than 6,450 cGy), 19 (70%) had three courses of cisplatin, and eight had only two courses, six due to drug toxicity. Twenty-six patients with stage IV disease were compared with 78 patients treated with radiotherapy alone by the Radiation Therapy Oncology Group (RTOG). The disease-free survival (DFS), overall survival, and the incidence of distant organ metastasis appear to be better in the combined group. It was concluded that the combination of chemo-radiotherapy in patients with locally advanced NPC needs to be evaluated in a phase III randomized trial.
We previously reported a patients who developed fulminant pneumococcal sepsis 12 years after successful treatment for Hodgkin's disease, which included splenic irradiation. We have since evaluated splenic size and function in 25 patients who had received splenic irradiation 5 to 16 years previously either for Hodgkin's disease (n = 19) or non-Hodgkin's lymphoma (n = 6). Mean maximum splenic diameter as measured on a 99mTc-sulfur colloid liver-spleen scan was 6.2 cm in the irradiated group and 9.7 cm in a control group (p less than 0.001). The mean percentage of erythrocytes containing pits when observed with interference phase microscopy was 13.0% in the irradiated group, which was significantly different (p less than 0.001) from the levels found in each of the control groups: normal subjects, 0.9%; unstaged and untreated lymphoma patients, 0.6%; and patients after splenectomy, 33.7%. Patients who have had splenic irradiation should be considered at risk of developing overwhelming pneumococcal sepsis.
58 cases of breast cancer treated primarily by radiotherapy were evaluated to determine the optimum dose for local control. Of 36 patients with T1 + T2 lesions who had tumorectomy prior to radiotherapy, incomplete excision of tumor was demonstrated on microscopic examination in 18. The minimum tumor dose to the breast was 4,500 rads in 5 weeks. Treatment failed to control local tumor in only 2 (5%) and metastases in 1.26 (72%) remained disease-free for 2 to 9 years. Of the 22 patients with T3 + T4 lesions, treatment failed to control both local tumor and metastases in 12 (54%); in those who received 6,000 rads or less in 6 weeks, treatment failed to control any of these lesions. 4,500-5,500 rads controlled the tumor in 95% of those with NO + N1 disease, compared to only half of those with N2 + N3 tumors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
