Radiation therapy alone or with concurrent low-dose daily either cisplatin or carboplatin in locally advanced unresectable squamous cell carcinoma of the head and neck: a prospective randomized trial.

Between January 1988 and December 1991, 159 patients with Stage III/IV (M0) squamous cell carcinoma of the head and neck were randomized to receive standard fraction RT (70 Gy) (group I) or the same RT plus either 6 mg/m2 of cisplatin (CDPP) (group II) or 25 mg/ m2 of carboplatin (CBDCA) both given daily during RT (group III). Patients in groups II and III had significantly higher overall response rates then those in group I (P = 0.011 and P = 0.0025, respectively) with no difference between groups II and III (P = 0.60). They also had significantly longer median survival time (MST) and higher 5-year survival rates than those in group I (MST, 32 months (32%) and 30 months (29%) versus 16 months (15%), respectively; P = 0.011 and P = 0.019, respectively), with no difference between the two RT/CHT groups. Median time to local recurrence (MTLR) and 5-year local recurrence-free survival (LRFS) were significantly higher for both RT/CHT when compared to RT alone (MTLR, not attained yet and 30 months versus 10 months, respectively; 5-year LRFS, 51% and 48% versus 27%, respectively; P = 0.018 and P = 0.040, respectively) with no difference between the two RT/CHT groups. There was no difference between the three treatment groups regarding regional lymph node and distant metastasis control. Apart from acute high grade (> or =3) hematological toxicity that was significantly more frequent in the two RT/CHT groups and no different between the two RT/CHT groups, other acute high grade toxicity was similar between the three treatment groups. Late high grade toxicity was infrequent and similar between the three treatment groups.

[Exteriorized cholesteatoma of the maxillary sinus]. / Eksteriorizovani holesteatom maksilarnog sinusa.

Cholesteatoma of the maxillary sinus is a very rare phenomenon, and there are only 43 published cases. The aetiology has not yet been completely explained, and relapses are very often. the authors describe a rare case of cholestesatoma of the maxillary sinus with exteriorisation and big destruction of sinus bone walls which did not differ from the malignant maxillary sinus. Radical surgery, using the operating microscope and microsurgical instruments, gave very good results, and there was no relapse ten years later.

[Carboplatin-etoposide-bleomycine chemotherapy protocol in the treatment of patients with metastatic non-seminomatous germ-cell testicular tumours with good prognosis]. / Hemoterapijski protokol karboplatini-etopozid-bleomicin u lecenju bolesnika s metastatskim neseminomskim tumorima germinacionih celija testisa s dobrom prognozom.

Fifteen patients with metastatic non-seminomatous germ-cell tumours with good prognosis were treated with carboplatin-etoposide-bleomycine chemotherapy. Patients were followed-up from 8 to 56 months (median 32 months). In 13 patients there was no evidence of the disease and in 2 patients recurred, but recovered after the subsequent secondary chemotherapy (cisplatin-bleomycine-vincristine). Signs and symptoms of toxicity included alopecia in 93% of patients, nausea and vomiting in 40%, while in respect of haematological toxicity, leucopenia was observed in all 15 patients, thrombocytopenia in 80%, and decrease of haemoglobinaemia in 60% of patients. Other toxicities were not observed. Carboplatin-etoposide-bleomycine chemotherapy is effective and little toxic, but a greater number of patients and a longer follow-up are needed for definitive evaluatin of this therapy in the treatment of patients with metastatic non-seminomatous germ-cell testicular tumours with good prognosis.

Carboplatin and etoposide chemotherapy regimen for recurrent malignant glioma: a phase II study.

PURPOSE: A phase II study that used combination chemotherapy with carboplatin (CBDCA) and etoposide (VP 16) (CE) was performed on patients with recurrent malignant glioma to investigate tumor control and toxicity. PATIENTS AND METHODS: Thirty-eight patients were treated with CBDCA 300 mg/m2 on days 1 to 3 and VP 16 100 mg/m2 on days 1 to 5. A minimum of three courses were required unless the patient had a rapid progression of disease (PD). Courses were repeated every 4 weeks. RESULTS: We observed partial responses (PRs) in eight of 38 patients (21%), stable disease (SD) in 12 of 38 (32%), whereas 18 of 38 (47%) patients had PD. The median time to tumor progression (TTP) for PR and SD patients was 42.5 weeks, whereas the median survival time (MST) for PR and SD patients was 47.5 weeks. Three groups of toxicities were observed: hematologic, gastrointestinal, and hepatic. No grade 4 Eastern Cooperative Oncology Group toxicity was observed. CONCLUSIONS: This regimen has shown at least comparable results with other series that used platinum-based agents. Further studies that use these agents in various-dose schedules and drug combinations are warranted.

Metastatic squamous cell carcinoma of an unknown primary tumor localized to the neck.

68 patients with metastatic squamous-cell carcinoma (SCC) of an unknown primary tumor localized to the neck were treated between 1981 and 1990. There were 11 patients treated with radiotherapy alone, 24 patients treated with surgery and radiotherapy and 33 patients treated with radiotherapy and chemotherapy. Male to female ratio was 1.9:1 and the median age was 55 years (range, 33 to 71 years). 41 (61%) patients had N3 disease, 18 (26%) patients had N2 disease and 9 (13%) patients had N1 disease. The majority of N3 patients were treated with radiotherapy + chemotherapy (n = 17) and surgery + radiotherapy (n = 17). The complete response (CR) to radiotherapy + chemotherapy was 73% with 19 patients having no evidence of disease currently. The median survival time (MST of this group was 34+ months. Of the 35 patients who had surgery and/or radiotherapy, 7 (20%) currently have no evident disease. The MST of these two groups (combined) was 22 months. Patients with N3 disease who received radiotherapy + chemotherapy had a higher CR rate and longer MST when compared with those without chemotherapy.
