Teniposide or carboplatin in patients with recurrent or advanced cervical carcinoma: A randomized phase II trial

Thomsen TK, Pfeiffer P, Bertelsen K. Teniposide or carboplatin in patients with recurrent or advanced cervical carcinoma: A randomized phase II trial. Int J Gynecol Cancer 1998; 8 : 310–314.
The aim of the present study was to investigate response rates, time to progression, and survival with teniposide or carboplatin in patients with advanced or recurrent cervical cancer and to estimate the toxicity of each drug regimen.
Twenty-eight patients with recurrent or advanced cervical cancer entered the study. Two patients were ineligible (severe renal impairment, n = 1; performance status 3, n = 1) and were excluded from the analysis. The remaining 26 patients were randomized to either carboplatin (400 mg/m² on day 1, intravenously every four weeks) or teniposide (125 mg/m² on days 1, 2 and 3, intravenously every four weeks). Twelve patients were randomized to the carboplatin arm and 14 patients to the teniposide arm. They were all comparable with respect to age, performance status, histology, primary FIGO stage, and prior therapy.
Response was seen in four patients in each group (33% and 29%, respectively), all but one being partial. (One patient in the teniposide group had complete response). Time to progression and median survival were similar in the two groups (median time to progression 20/17 weeks and median survival 40/41 weeks, respectively.)
In general, toxicity was moderate. Leukopenia (WHO grade 3 or 4) was seen in one patient treated with teniposide, and thrombocytopenia (WHO grade 3 or 4) in one patient treated with carboplatin. Eleven patients (79%) in the teniposide group had alopecia requiring a wig. The study implies that both drugs have some activity in cervical cancer. Carboplatin has the advantage that it can be administered on an out-patient basis.

Simultaneous radio‐ and chemotherapy for squamous cell carcinoma of the head and neck in daily clinical practice: 5 years experience in a University Hospital

Several randomized studies and meta‐analyses have shown that simultaneous radio‐ and chemotherapy prolongs survival in patients with unresectable squamous cell carcinoma of the head and neck as compared with conventional radiotherapy. We assessed the feasibility and effectiveness of simultaneous radiotherapy (35 × 2 Gy) and chemotherapy [cisplatinum 100 mg/m² or carboplatin (AUC 6) on days 1, 22 and 43] in daily clinical practice in a cohort of 87 patients treated at our institute between 1998 and 2002. Eighty patients completed radiotherapy according to schedule. Eighty patients received two courses of chemotherapy and 50 patients three courses. Nephrotoxity, bone marrow suppression and ototoxicity were the most frequent side‐effects. Median weight loss was 8.5%. Median survival was 15 months and 44% of the patients were alive at 2 years. Patients receiving three courses of chemotherapy had a better survival than patients receiving two or less courses. Treatment with simultaneous radio‐ and chemotherapy for advanced head and neck cancer is a demanding, but feasible treatment in daily clinical practice. Survival seems to be comparable with the results achieved in patients selected for clinical trials.     

Neoadjuvant chemotherapy with cisplatin, aclacinomycin A, and mitomycin C for cervical adenocarcinoma – a preliminary study

Between 1989 and 2002, 28 patients with locally advanced cervical adenocarcinoma (bulky IB-IIIB) were recruited for a pilot study aimed at evaluation of the effectiveness of neoadjuvant chemotherapy with cisplatin, aclacinomycin-A, and mitomycin-C (PAM), followed by radical surgery. This regimen was administrated intra-arterially or intravenously. In addition to patients treated with PAM, we retrospectively analyzed the prognoses of 26 patients in stage I and II, who had been treated between 1975 and 1981 with radical surgery with/without radiation therapy. Twenty-eight patients received PAM therapy as neoadjuvant chemotherapy, and 75.0% of the 16 intra-arterially infused patients showed a response, as did 66.7% of the 12 intravenously infused patients. There was a significant difference in the 5-year prognosis of stage II (PAM group, 72.9%; without-PAM group, 36.4%). The results suggest that, as the free space in the parametrium is widened by neoadjuvant chemotherapy with PAM, it is possible that the tumor could be completely resected by radical hysterectomy. Thus, neoadjuvant chemotherapy with PAM is expected to improve the survival rate of patients with advanced cervical adenocarcinoma by the preliminary study. However, the survival rates of stage II with lymph node metastasis in the without-PAM group seem low, and we must also consider that the various technologies to evaluate and treat the cervical adenocarcinomas, e.g. computed tomography, magnetic resonance imaging, and surgical equipments, had improved during 1989-2002 than was the scenario during 1975-1981, and these improvements contributed to better prognosis. A prospective-randomized study is needed to assess the value of this approach compared with standard management.     

Placental site trophoblastic tumor in a patient with brain and lung metastases

Placental site trophoblastic tumor is a rare neoplasm that arises from intermediate trophoblasts and shows diversity of biological behaviors, resulting in the absence of consistency in treatment modalities. A case of placental site trophoblastic tumor that extended to the cervix, with primary manifestation of amenorrhea and yellow foul-smelling vaginal discharge, is presented. Total abdominal hysterectomy was performed initially, and serial measurements of human chorionic gonadotropin levels were obtained. She was admitted with metastases to brain and lung 1.5 years after surgery. Combination chemotherapy (etoposide-methotrexate-dactinomycin/cyclophosphamide-vincristine) and radiotherapy were administered. There was no significant response to chemoradiotherapy. Despite changing chemotherapy regimen, she is still alive with progressive disease.     

下咽癌120例临床疗效的回顾性分析

目的探讨下咽癌单纯手术、术后放疗和术后放疗 化疗的临床疗效。方法回顾性分析1979年2月~2002年10月收治的下咽癌120例。单纯手术组(简称S组)30例,术后放疗组(简称S R组)60例,术后放疗和化疗组(简称S R C组)30例。随访中位时间42.7个月。结果根据Kaplan-Meier方法统计S组、S R组、S R C组3、5年生存率分别为34.9%、30.4%,47.5%、42.9%,56.1%、47.3%。S组3、5年生存率和S R组及S R C组3、5年生存率存在显著性差异(χ2=8.87,P=0.003,χ2=4.74,P=0.029,χ2=11.47,P=0.009,χ2=13.22,P=0.001),S R组和S R C组3年生存率存在显著性差异(χ2=3.42,P=0.047),S R组和S R C组5年生存率差异无显著性(χ2=2.60,P=0.279)。结论术后放疗明显提高了下咽癌3、5年生存率,应该成为下咽癌首选的治疗方法。合并化疗的综合治疗未能明显提高下咽癌5年生存率。     

Weekly paclitaxel as first-line chemotherapy in elderly advanced breast cancer patients: a phase II study of the Gruppo Italiano di Oncologia Geriatrica (GIOGer).

BACKGROUND: First-line chemotherapy regimens suitable for elderly advanced breast cancer patients are still not defined. PATIENTS AND METHODS: Women with stage III or IV breast cancer aged > or =70 years were enrolled in a phase II study aimed to evaluate both activity and toxicity of weekly paclitaxel. Among 46 planned patients, at least 18 responses and not more than seven unacceptable toxic events are required for a favourable conclusion. Paclitaxel 80 mg/m(2) was administered weekly for 3 weeks every 28 days. RESULTS: Unacceptable toxicity occurred in seven out of 46 patients evaluated for toxicity [15.2%; exact 95% confidence interval (CI) 7.6% to 28.2%] and was represented by one case of febrile neutropenia, one case of severe allergic reaction and five cases of cardiac toxicity. Among 41 patients evaluated for response, a complete response occurred in two (4.9%) patients and a partial response in 20 (48.8%), with an overall response rate of 53.7% (exact 95% CI 38.7% to 67.9%). The median progression-free survival was 9.7 months (95% CI 8.5-18.7) and median survival was 35.8 months (95% CI 19-not defined). CONCLUSIONS: Weekly paclitaxel is highly active in elderly advanced breast cancer patients. Data on cardiovascular complications, however, indicate the need for a careful monitoring of cardiac function before and during chemotherapy.     

Second-line (post-study) chemotherapy received by patients treated in the phase III trial of pemetrexed plus cisplatin versus cisplatin alone in malignant pleural mesothelioma.

BACKGROUND: A phase III trial in patients with malignant pleural mesothelioma demonstrated a survival advantage for pemetrexed plus cisplatin compared with single-agent cisplatin. Because post-study chemotherapy (PSC) may have influenced the outcome of the trial, we examined its use and association with survival. PATIENTS AND METHODS: Eighty-four patients from the pemetrexed plus cisplatin arm and 105 patients from the single-agent cisplatin arm received PSC. Kaplan-Meier survival estimates were compared by treatment groups, and by PSC and non-PSC subgroups. RESULTS: The percentage of patients receiving PSC was imbalanced between the treatment arms. Fewer pemetrexed plus cisplatin treated patients received PSC (37.2% versus 47.3%). A multiple regression analysis performed in this trial showed that PSC had a statistically significant correlation with prolonged survival (P <0.01), adjusting for baseline prognostic factors and treatment intervention. The adjusted hazard ratio for PSC over non-PSC subgroups was 0.56 (confidence interval 0.44-0.72). CONCLUSIONS: PSC in malignant pleural mesothelioma was significantly associated with prolonged survival. It is not known whether the reduced risk of death was associated with PSC or whether patients who had prolonged survival tended to receive more PSC. The pemetrexed plus cisplatin treatment group had a statistically significant survival advantage even though fewer patients from that arm of the trial received PSC. The potentially beneficial role of PSC should be assessed in prospective trials.
