Experience of treatment of lung cancer patients using paclitaxel and carboplatin.

Nineteen patients with stage III & IV nonsmall cell lung cancer were treated with a regimen containing paclitaxel and carboplatin at Dharmais National Cancer Center Hospital and Pertamina Central General Hospital, Jakarta, Indonesia. There were 14 males and 5 females, the histologic diagnosis being adenocarcinoma in 13 patients, squamous carcinoma in 5 patients and adenosquamous carcinoma in 1 patient. Fourteen patients were in stage IV, 4 had stage IIIB, and one had stage IIIA disease. The regimen contained paclitaxel 135-200 mg/m2, combined with carboplatin 300 mg/m2 or AUC 6 mg/ml.min, given every 3 weeks. Those who underwent at least 3 cycles of chemotherapy were followed up until death. Objective improvement (PR) was seen in 12 patients or 63%; 2 had stable disease (11%) and 5 had progressive disease (26%). Two patients are still alive at 17.5 months and 19 months after starting chemotherapy. The one-year survival rate was 58%, and median survival time was 14 months.

A prospective randomized study of Chop versus Chop plus alpha-2B interferon in patients with intermediate and high grade non-Hodgkin's lymphoma: the International Oncology Study Group NHL1 Study .

UNLABELLED: The addition of a brief alpha interferon regimen to each CHOP induction cycle, plus one year of alpha interferon thrice weekly maintenance therapy, has no early effect on response rates or survival in patients with Intermediate or High grade cell NHL. BACKGROUND: The CHOP (Cyclophosphamide, Adriamycin. Vincristine, Prednisone) regimen is the most widely used first-line therapy for patients with Intermediate or High Grade (IG/HG) non-Hodgkin's lymphoma (NHL). Alpha 2b interferon (INF) enhances response rates and improves survival in low-grade NHL. The International Oncology Study Group (IOSG) conducted a prospective randomized study comparing CHOP alone or combined with INF in patients with IG/HG-NHL. The primary study aim was to compare the objective response rates in these patient cohorts. PATIENTS AND METHODS: Patients with a confirmed diagnosis of measurable NHL of International Working Formulation (IWF) groups D to H histology were randomized to receive CHOP alone or CHOP with 5Mu INF s.c. for 5 days on days 22 to 26 of each 28 day cycle with INF 5 million units (Mu) given three times per week subcutaneously for 52 weeks in those patients who responded to CHOP plus INF. RESULTS: The overall response rates were equivalent in both groups: CHOP alone (214 patients) 81% (complete 55%, partial 26%); CHOP plus INF (221 patients) 80% (complete 54%, partial 26%). At 36 months, the actuarial survival rate was equivalent in both groups. CONCLUSIONS: There is no apparent early advantage in terms of response or survival conferred by adding the study INF regimen to CHOP therapy for patients with IG/HG-NHL.

Preliminary report of the Asian-Oceanian Clinical Oncology Association randomized trial comparing cisplatin and epirubicin followed by radiotherapy versus radiotherapy alone in the treatment of patients with locoregionally advanced nasopharyngeal carcinoma. Asian-Oceanian Clinical Oncology Association Nasopharynx Cancer Study Group.

BACKGROUND: The aim of this trial was to compare the outcome achieved with neoadjuvant chemotherapy followed by radiotherapy to that achieved with radiotherapy alone for patients with locoregionally advanced undifferentiated or poorly differentiated nasopharyngeal carcinoma (NPC) meeting one of the following criteria: Ho's T3 disease, Ho's N2-N3 disease, or lymph node size > or =3 cm. METHODS: Between September 1989 and August 1993, 334 patients were enrolled in the study, with equal numbers of patients randomized to the neoadjuvant chemotherapy arm (CT arm) and the radiotherapy arm (RT arm). Neoadjuvant chemotherapy consisting of 2-3 cycles of cisplatin (60 mg/m2 on Day 1) and epirubicin (110 mg/m2 on Day 1) followed by radiotherapy was given to the CT arm. For radiotherapy, a dose of 66-74 gray (Gy) (median, 71 Gy) was delivered to the primary tumor and 60-76 Gy (median, 66 Gy) to the neck. Two hundred eighty-six eligible patients completed the treatment and were evaluable for treatment response (134 in the CT arm, 152 in the RT arm). All patients were included in the survival analysis based on the intention to treat. The median follow-up was 30 months for the whole cohort and 41 months for the surviving patients. RESULTS: Analysis of the 334 patients based on the intention to treat showed no significant difference in relapse free survival (RFS) or overall survival (OS) between the 2 treatment arms (3-year RFS rate: 48% in the CT arm vs. 42% in the RT arm, P = 0.45; 3-year OS rate: 78% vs. 71%, P = 0.57). In an efficacy analysis based on only the 286 evaluable patients, a trend of improved RFS favoring the CT arm was observed (3-year RFS rate: 58% vs. 46%, P = 0.053), with again no significant difference in OS (3-year OS rate: 80% vs. 72%, P = 0.21). In the subgroup of 49 patients with bulky neck lymph nodes >6 cm, improved RFS (3-year RFS rate: 63% vs. 28%, P = 0.026) and OS (3-year OS rate: 73% vs. 37%, P = 0.057) were observed, favoring the CT arm. CONCLUSIONS: This multicenter randomized study did not demonstrate any benefit with the addition of cisplatin-epirubicin neoadjuvant chemotherapy for patients with locoregionally advanced nasopharyngeal carcinoma; therefore routine administration of neoadjuvant chemotherapy to this target group cannot be recommended. Although the overall incidence of recurrence was reduced with the addition of chemotherapy in the efficacy analysis, the overall survival was not affected. A more effective chemotherapy regimen, the selection of an appropriate target group, and the use of an alternative strategy for combining chemoradiotherapy should be explored in future trials.
