ABSTRACT
PURPOSE: The LORHA study described the clinical features of patients and tumours in long-term responders from a subset of breast cancer patients who responded to 1st-line trastuzumab and without disease progression. METHODS: This was an ambispective, multicentre, non-interventional study conducted in 57 centres in France. Eligible patients were women with HER2+metastatic or locally-advanced breast cancer, treated with 1st-line therapy, progression-free for ≥3 years after starting trastuzumab, and followed-up for 12 months. RESULTS: 160 patients were recruited, 128 were included in the efficacy analysis subset (median age: 61 years; [34-95 years]). A majority (88%) had invasive ductal carcinoma; 53% had SBR grade III carcinoma, and 58% were positive for hormonal receptors. The median time since diagnosis was 8 years [3-26 years]. The most frequent metastatic sites were the bone, liver, lymph nodes, and lungs in 43%, 35%, 20% and 19% of patients, respectively. The median duration of 1st-line trastuzumab was 4.5 years [0.8-12.1], combined with paclitaxel and docetaxel in 35 and 72 patients, respectively. Median PFS (progression-free survival) was 6.4 years [5.7; Not Reached]. No trastuzumab-related deaths were observed. In the safety analysis subset (N = 134), 3 cardiac adverse events considered related to trastuzumab were recorded in 3 patients (2.2%), and only one prospective congestive cardiac failure was of grade ≥3. CONCLUSIONS: The LORHA study showed that long term responders to 1st-line trastuzumab for locally advanced or metastatic breast cancer could achieve a median PFS of more than 6 years, with an acceptable safety profile.

BACKGROUND: CA-125 as a tumour progression criterion in relapsing ovarian cancer (ROC) trials remains controversial. CALYPSO is a large randomised trial incorporating CA-125 (GCIG criteria) and symptomatic deterioration in addition to Response Evaluation Criteria in Solid Tumours (RECIST) criteria (radiological) to determine progression. METHODS: In all, 976 patients with platinum-sensitive ROC were randomised to carboplatin-paclitaxel (C-P) or carboplatin-pegylated liposomal doxorubicin (C-PLD). CT-scan and CA-125 were performed every 3 months until progression. RESULTS: In all, 832 patients (85%) progressed, with 60% experiencing a first radiological progression, 10% symptomatic progression, and 28% CA-125 progression without evidence of radiological or symptomatic progression. The benefit of C-PLD vs C-P in progression-free survival was not influenced by type of first progression (hazard ratio 0.85 (95% confidence interval (CI): 0.66-1.10) and 0.84 (95% CI: 0.72-0.98) for CA-125 and RECIST, respectively). In patients with CA-125 first progression who subsequently progressed radiologically, a delay of 2.3 months was observed between the two progression types. After CA-125 first progression, median time to new treatment was 2.0 months. In all, 81%of the patients with CA-125 or radiological first progression and 60% with symptomatic first progression received subsequent treatment. CONCLUSION: CA-125 and radiological tests performed similarly in determining progression with C-PLD or C-P. Additional follow-up with CA-125 measurements was not associated with overtreatment.

BACKGROUND: Very effective trastuzumab-based primary systemic therapy (PST) can be proposed for conservative surgery purpose to human epidermal growth factor receptor 2 (HER2)-positive breast cancer (HER2+BC). Long-term follow-up (LTFU) warrants further data. PATIENTS AND METHODS: LTFU of patients, with stage II/III HER2+BC, treated by trastuzumab associated with docetaxel (Taxotere(®)) and/or carboplatin used as anthracycline-free PST was studied. RESULTS: Among 135 patients, with a median follow-up of 48.3 months [95% confidence interval (CI) 45.3-52.4 months], the relapse-free survival (RFS) rate was 73.2% (95% CI 63.76% to 80.55%) while the overall survival (OS) rate was 91.87% (95% CI 84.23% to 95.90%). Adjuvant trastuzumab favorably influenced RFS in univariate analysis while the pathological nodal invasion unfavorably influenced RFS [Cox multivariate analysis (hazard ratio = 2.80, 95% CI 1.36-5.76, P = 0.0052)] and OS. Cardiac toxicity was minor (2.2% transient, reversible asymptomatic decrease in left ventricular ejection fraction). CONCLUSION: This is the first report of LTFU showing that anthracycline-free trastuzumab-based PST combined either with docetaxel and/or carboplatin can achieve, without cardiac toxicity, very competitive results in terms of pathological complete response, RFS and OS, in HER2+BC. The choice of this schedule could be proposed to patients with vascular contraindication for anthracyclines or because patient's or physician's preference for a taxane-only schedule.

Irinotecan (CPT11) has established activity in the treatment of advanced colorectal cancer without cross-resistance with established 5-fluorouracil/folinic acid-based therapy. This phase II study was conducted to establish the efficacy and tolerance of combination treatment with irinotecan and 5-fluorouracil as salvage treatment for this disease. Open phase II trial of CPT11 180 mg/m2 on day 1, leucovorin 200 mg/m2 on days 1 and 2, and 5-fluorouracil 400 mg/m2 loading dose followed by 600 mg/m2 infusion on days 1 and 2. Treatment was continued until progression or limiting toxicity. Responders could proceed to surgical resection of residual disease. Thirty-nine patients from 2 institutions received a total of 287 cycles of therapy (median 7 cycles/patient). Eight patients achieved an objective response (7 for liver metastasis and 1 for lung metastasis), and an additional 12 obtained stabilization of disease or minor responses (MR); of these patients, 8 with liver metastasis (7 partial response and 1 MR) underwent hepatic resection of metastases and all them obtained a complete response. The median duration of response was 14 months, and the median survival was 11 months. Hematologic toxicity (neutropenia) was the most common serious side effect (29% of patients in 2% of cycles), but significant fever developed in only 4 patients. Grade III diarrhea was experienced in at least 1 cycle by 10% of patients. The results of this schedule compare favorably with previously reported experience of a phase I study designed to establish the dose of CPT11. Efficacy in this poor prognosis group of patients is very encouraging, and the schedule is well tolerated by even previously treated patients.

Tremendous progress has been made in the medical treatment of advanced colorectal cancer during the past 2 to 3 years, due to the availability of several new drugs. Of these new agents, irinotecan (CPT-11 [Camptosar]) seems to be one of the most active against advanced colorectal cancer. It is, therefore, a good candidate for combination with the more classic cytotoxic agents for this disease. This article summarizes several European phase I and II studies in which irinotecan has been combined with (1) fluorouracil (5-FU) alone, given as a repeated bolus injection or a protracted infusion; (2) 5-FU modulated by folinic acid (leucovorin) according to different schedules; or (3) mitomycin (Mutamycin). All of these studies have demonstrated clinical responses in patients with advanced colorectal carcinoma, including complete responses. The toxicity profiles of the various combinations seem to be acceptable; neutropenia and delayed diarrhea are the most frequent side effects. Large phase III studies are still warranted to demonstrate the benefit of these irinotecan-based regimens.

The aim of this study was to define the efficacy of a combination of cisplatin, 5-fluorouracil (5-FU), leucovorin, and etoposide (VP-16) in locally advanced or metastatic non-small-cell lung cancer (NSCLC). From September 1991 to November 1994, 28 patients were treated with cisplatin, 100 mg/m2 i.v. on day 1; 5-FU and leucovorin, 500 mg/m2 on days 1, 2, 3, and 4 by i.v. continuous infusion; and VP-16, 70 mg/m2 i.v. on days 1, 2, 3, and 4 (combination, PFL-VP-16). Cycles were repeated every 3 weeks. There were 22 men and six women. The median age was 58 (range, 41-76). All had measurable diseases (one was stage IIIA, six were IIIB, and 21 were IV). None had previously received chemotherapy for metastatic disease. There was one complete response and six partial responses, for an overall response rate of 25% (95% confidence interval 9-41%). The median response duration and the overall survival were 8 and 9 months, respectively. Limiting toxicity was myelosuppression and oral mucositis. Grade 3 or 4 leucopenia was observed in 20% of all of the 95 cycles administered, and oral mucositis in 13%. No grade 3 or 4 renal toxicity occurred, and neurologic toxicities were limited (3% of the 28 patients experienced grade 3). PFL-VP-16 is active and can easily be administered to patients with advanced NSCLC. However, according to the results obtained with this schedule, VP-16 does not increase either response rate or survival compared with the regimen previously described by Vokes et al. (PFL).

The clinical activity and toxicity of the triple combination of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ), cyclophosphamide, and cisplatin was assessed in both previously treated and untreated women with advanced ovarian carcinoma. Paclitaxel 175 mg/m2 was administered over 3 hours following standard premedication (prednisolone, dexchlorpheniramine, and cimetidine). Cisplatin 80 mg/m2 and cyclophosphamide 600 mg/m2 were given 6 to 12 hours after paclitaxel. Treatment was given at 3-week intervals for six cycles. Twenty-seven patients entered the study; 23 were evaluable for toxicity and 17 for response. Paclitaxel appeared to add additional efficacy to the standard cisplatin/cyclophosphamide regimen. Both the overall and complete remission rates were very high (88% and 70%, respectively), and histologically confirmed complete remissions exceeded 60%. Longer follow-up is needed to determine the duration of these responses. The primary toxicities included leukoneutropenia, peripheral neuropathy, asthenia, and alopecia. Only two of 23 patients withdrew because of toxicity, however, and only two treatment cycles were complicated by neutropenic fever requiring intravenous antibiotics. No life-threatening toxicities were encountered, although the peripheral neuropathy was poorly and slowly reversible and may have a significant impact on the patients' quality of life.

In this phase I/II study, we assessed the impact of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in the treatment of advanced ovarian carcinoma combined with the standard regimen cisplatin/cyclophosphamide given as follows: paclitaxel 175 mg/m2 (over 3 hours perfusion with standard premedication), cisplatin 80 mg/m2 (6 to 12 hours after paclitaxel), and cyclophosphamide 400 mg/m2. From February 1994 to January 1996, 27 patients (median age, 55 years; age range, 35 to 74 years) were entered into the study. Eight patients had distant metastases and 19 had early locoregional disease (stage III, 18 patients; stage IC, one patient). Twenty-two patients had undergone prior surgery (simple biopsy, six patients; optimally debulked, nine patients; suboptimally debulked, seven patients). Twenty-one patients had received no prior chemotherapy and six were previously treated with at least one platinum-based regimen. A maximum of six courses of paclitaxel/cisplatin/cyclophosphamide were given every 21 days. Twenty-three patients were evaluable for toxicity: neutropenia (World Health Organization grade 3/4), 91% of patients; thrombopenia (World Health Organization grade 3/4), 13% of patients; two episodes of neutropenia with fever; and neurotoxicity grade 3, 17% of patients. Alopecia grade 3 was reported in all patients. No hypersensitivity reactions and no cardiac toxicity was observed. Among 17 patients evaluable for response (patients with stage IV disease or stage III suboptimally debulked), 12 (70%) clinical complete responses (CRs) and three (18%) partial responses were observed. Among the 12 patients with CRs, 10 underwent second-look laparotomy and seven of them (70%) achieved a pathologic CR. In the group of 11 chemotherapy-naive patients evaluable for response, eight (72%) achieved a CR and three (28%) achieved a partial response. This combination seems to be safe, with very acceptable toxicity, and also seems to be highly active in the treatment of patients with advanced ovarian carcinoma.

Prognosis in metastatic malignant melanoma is poor because of chemo and radiotherapy resistance. However, some drugs, such as dacarbazine, cisplatinum or fotemustine, a new nitrosourea, have produced a response rate of more than 20%. Combining these drugs increases response rate to 30-40%. Immunotherapy by interferon-alpha 2 shows about 15-20% response rate but interleukin-2 would be more effective especially in combination with cisplatinum and interferon-alpha 2 with 50% response and long survival after cessation of treatment.
