Randomized trial on adjuvant treatment with FOLFIRI followed by docetaxel and cisplatin versus 5-fluorouracil and folinic acid for radically resected gastric cancer.

BACKGROUND: Some trial have demonstrated a benefit of adjuvant fluoropirimidine with or without platinum compounds compared with surgery alone. ITACA-S study was designed to evaluate whether a sequential treatment of FOLFIRI [irinotecan plus 5-fluorouracil/folinic acid (5-FU/LV)] followed by docetaxel plus cisplatin improves disease-free survival in comparison with 5-FU/LV in patients with radically resected gastric cancer. PATIENTS AND METHODS: Patients with resectable adenocarcinoma of the stomach or gastroesophageal junction were randomly assigned to either FOLFIRI (irinotecan 180 mg/m(2) day 1, LV 100 mg/m(2) as 2 h infusion and 5-FU 400 mg/m(2) as bolus, days 1 and 2 followed by 600 mg/m(2)/day as 22 h continuous infusion, q14 for four cycles) followed by docetaxel 75 mg/m(2) day 1, cisplatin 75 mg/m(2) day 1, q21 for three cycles (sequential arm) or De Gramont regimen (5-FU/LV arm). RESULTS: From February 2005 to August 2009, 1106 patients were enrolled, and 1100 included in the analysis: 562 in the sequential arm and 538 in the 5-FU/LV arm. With a median follow-up of 57.4 months, 581 patients recurred or died (297 sequential arm and 284 5-FU/LV arm), and 483 died (243 and 240, respectively). No statistically significant difference was detected for both disease-free [hazard ratio (HR) 1.00; 95% confidence interval (CI): 0.85-1.17; P = 0.974] and overall survival (OS) (HR 0.98; 95% CI: 0.82-1.18; P = 0.865). Five-year disease-free and OS rates were 44.6% and 44.6%, 51.0% and 50.6% in the sequential and 5-FU/LV arm, respectively. CONCLUSIONS: A more intensive regimen failed to show any benefit in disease-free and OS versus monotherapy. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01640782.

Sorafenib in patients with advanced biliary tract carcinoma: a phase II trial.

BACKGROUND: Advanced biliary tract carcinoma has a very poor prognosis, with chemotherapy being the mainstay of treatment. Sorafenib, a multikinase inhibitor of VEGFR-2/-3, PDGFR-beta, B-Raf, and C-Raf, has shown to be active in preclinical models of cholangiocarcinoma. METHODS: We conducted a phase II trial of single-agent sorafenib in patients with advanced biliary tract carcinoma. Sorafenib was administered at a dose of 400 mg twice a day. The primary end point was the disease control rate at 12 weeks. RESULTS: A total of 46 patients were treated. In all, 26 (56%) had received chemotherapy earlier, and 36 patients completed at least 45 days of treatment. In intention-to-treat analysis, the objective response was 2% and the disease control rate at 12 weeks was 32.6%. Progression-free survival (PFS) was 2.3 months (range: 0-12 months), and the median overall survival was 4.4 months (range: 0-22 months). Performance status was significantly related to PFS: median PFS values for ECOG 0 and 1 were 5.7 and 2.1 months, respectively (P=0.0002). The most common toxicities were skin rash (35%) and fatigue (33%), requiring a dose reduction in 22% of patients. CONCLUSIONS: Sorafenib as a single agent has a low activity in cholangiocarcinoma. Patients having a good performance status have a better PFS. The toxicity profile is manageable.

Global Lung Oncology Branch trial 3 (GLOB3): final results of a randomised multinational phase III study alternating oral and i.v. vinorelbine plus cisplatin versus docetaxel plus cisplatin as first-line treatment of advanced non-small-cell lung cancer.

BACKGROUND: The study compared the efficacy of a first-line treatment with day 1 i.v. vinorelbine (NVBiv) and day 8 oral vinorelbine (NVBo) versus docetaxel (DCT) in a cisplatin-based combination in advanced non-small-cell lung cancer, in terms of time to treatment failure (TTF), overall response, progression-free survival (PFS), overall survival (OS), tolerance and quality of life (QoL). METHODS: Patients were randomly assigned to receive cisplatin 80 mg/m2 with NVBiv 30 mg/m2 on day 1 and NVBo 80 mg/m2 on day 8 every 3 weeks, after a first cycle of NVBiv 25 mg/m2 on day 1 and NVBo 60 mg/m2 on day 8 (arm A) or cisplatin 75 mg/m2 and DCT 75 mg/m2 on day 1 every 3 weeks (arm B), for a maximum of six cycles in both arms. RESULTS: From 2 February 2004 to 1 January 2006, 390 patients were entered in a randomised study and 381 were treated. The patient characteristics are as follows (arms A/B): metastatic (%) 80.5/84.8; patients with three or more organs involved (%) 45.3/40.8; median age 59.4/62.1 years; male 139/146; squamous (%) 34.2/33.5; adenocarcinoma (%) 41.6/39.3; median TTF (arms A/B in months) [95% confidence interval (CI)]: 3.2 (3.0-4.2), 4.1 (3.4-4.5) (P = 0.19); overall response (arms A/B) (95% CI): 27.4% (21.2% to 34.2%), 27.2% (21.0% to 34.2%); median PFS (arms A/B in months) (95% CI): 4.9 (4.4-5.9), 5.1 (4.3-6.1) (P = 0.99) and median OS (arms A/B in months) (95% CI): 9.9 (8.4-11.6), 9.8 (8.8-11.5) (P = 0.58). The median survival for squamous histology was 8.87/9.82 months and for adenocarcinoma 11.73/11.60 months for arms A and B, respectively. Main haematological toxicity was grade 3-4 neutropenia: 24.4% (arm A) and 28.8% (arm B). QoL as measured by the Lung Cancer Symptom Scale was similar in both arms. CONCLUSIONS: Both arms provided similar efficacy in terms of response, time-related parameters and QoL, with an acceptable tolerance profile. In the current Global Lung Oncology Branch trial 3, NVBo was shown to be effective as a substitute for the i.v. formulation. This can relieve the burden of the i.v. injection on day 8 and can optimise the hospital's resources and improve patient convenience.

Timing of adjuvant chemotherapy and tamoxifen in women with breast cancer: findings from two consecutive trials of Gruppo Oncologico Nord-Ovest-Mammella Intergruppo (GONO-MIG) Group.

BACKGROUND: The timing of adjuvant chemotherapy and tamoxifen (TAM) has been investigated only in postmenopausal women with breast cancer. We analyzed the outcome of both pre- and postmenopausal women who entered two randomized trials (Gruppo Oncologico Nord-Ovest-Mammella Intergruppo studies) on adjuvant chemotherapy and received either concomitant or sequential TAM. PATIENTS AND METHODS: Patients who received anthracycline-based regimens and either concomitant or sequential TAM were eligible. The primary end point was overall survival (OS). Hazard ratios (HRs) of death or recurrence for treatment comparisons were estimated by Cox proportional hazards regression models. RESULTS: Among the 1096 eligible patients, 507 (46.3%) and 589 (53.7%) received concomitant and sequential TAM, respectively. The median follow-up time was 6.6 years. Ten-year OS was 83% [95% confidence interval (CI) 78-88%] and 80% (95% CI 74-86%) in the concomitant and sequential groups, respectively. Multivariate analyses confirmed no significant difference in the hazard of death (HR = 1.13; 95% CI 0.78-1.64; P = 0.534) and recurrence (HR = 1.03; 95% CI 0.80-1.33; P = 0.88) between the two groups. A decreasing trend (P = 0.015) in HR of death with increasing age was observed indicating, that concomitant therapy might be more effective than sequential therapy in young patients. CONCLUSIONS: We observed no outcome difference between sequential and concomitant chemo-endocrine therapy. The potential advantage of concomitant TAM in young patients needs to be further addressed in prospective trials.

Phase II study of pemetrexed in combination with carboplatin in patients with malignant pleural mesothelioma (MPM).

BACKGROUND: The aim of this study was to evaluate the activity and toxicity of pemetrexed and carboplatin combination as first-line chemotherapy in malignant pleural mesothelioma (MPM). PATIENTS AND METHODS: Patients with measurable advanced MPM and a zero to two Eastern Cooperative Oncology Group (ECOG) performance status (PS) were enrolled. The schedule was pemetrexed 500 mg/m(2) in combination with carboplatin area under the curve 5, every 21 days. In all, 76 patients were treated. Median age was 65 years; median ECOG PS was zero. RESULTS: Grade 3 hematological toxicity according to World Health Organization criteria was seen in 36 (47.3%) patients; grade 4 hematological toxicity in 5 (6.5%) patients. There were 16 (21%) partial responses and 3 (4%) complete responses, for an overall response rate of 19 (25%) [95% confidence interval (CI) 15.3-34.7]. In all, 29 (39%) (95% CI 28-48) patients reported stable disease. The median survival was estimated at 14 months. CONCLUSION: This combination of carboplatin and pemetrexed is moderately active and the toxicity is acceptable.

Gemcitabine in combination with oxaliplatin compared with gemcitabine alone in locally advanced or metastatic pancreatic cancer: results of a GERCOR and GISCAD phase III trial.

PURPOSE: Gemcitabine (Gem) is the standard treatment for advanced pancreatic cancer. Given the promising phase II results obtained with the Gem-oxaliplatin (GemOx) combination, we conducted a phase III study comparing GemOx with Gem alone in advanced pancreatic cancer. PATIENTS AND METHODS: Patients with advanced pancreatic cancer were stratified according to center, performance status, and type of disease (locally advanced v metastatic) and randomly assigned to either GemOx (gemcitabine 1 g/m2 as a 100-minute infusion on day 1 and oxaliplatin 100 mg/m2 as a 2-hour infusion on day 2 every 2 weeks) or Gem (gemcitabine 1 g/m2 as a weekly 30-minute infusion). RESULTS: Three hundred twenty-six patients were enrolled; 313 were eligible, and 157 and 156 were allocated to the GemOx and Gem arms, respectively. GemOx was superior to Gem in terms of response rate (26.8% v 17.3%, respectively; P = .04), progression-free survival (5.8 v 3.7 months, respectively; P = .04), and clinical benefit (38.2% v 26.9%, respectively; P = .03). Median overall survival (OS) for GemOx and Gem was 9.0 and 7.1 months, respectively (P = .13). GemOx was well tolerated overall, although a higher incidence of National Cancer Institute Common Toxicity Criteria grade 3 and 4 toxicity per patient was observed for platelets (14.0% for GemOx v 3.2% for Gem), vomiting (8.9% for GemOx v 3.2% for Gem), and neurosensory symptoms (19.1% for GemOx v 0% for Gem). CONCLUSION: These results confirm the efficacy and safety of GemOx, but this study failed to demonstrate a statistically significant advantage in terms of OS compared with Gem. Because GemOx is the first combined treatment to be superior to Gem alone in terms of clinical benefit, this promising regimen deserves further development.

A phase II study of 5-fluorouracil and high-dose folinic acid in combination with cyclophosphamide and mitoxantrone for advanced breast cancer.

38 patients with advanced breast adenocarcinoma were treated in a phase II study with 5-fluorouracil and high-dose folinic acid combined with cyclophosphamide and mitoxantrone. 6 patients had received prior chemotherapy for advanced disease, all with an anthracycline-containing regimen. Treatment was generally well tolerated. The most common side-effect was myelosuppression, with 1 toxic death due to leukopenia-related sepsis. 1 patient developed severe congestive heart failure 12 months from the end of therapy. 36 patients were evaluable for response. The overall response rate was 55%. Median duration of response was 8 months and median survival time was 16 months. This regimen warrants further investigations.

Anthracycline containing regimens in intermediate grade lymphoma. Italian Cooperative Study Group on Intermediate Grade Malignant Lymphoma.

From March 1991 to April 1992, 44 previously untreated patients with stage II to IV intermediate-grade non-Hodgkin's lymphoma (according to the Kiel classification) were entered in a phase III comparative trial. The objectives of the study were to compare the efficacy and safety of using idarubicin instead of doxorubicin in the combination chemotherapeutic regimen CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone). Forty-four patients were randomly assigned to receive either CI(idarubicin)OP or CH(doxorubicin)OP. The study is ongoing and so far no significant differences in complete response rate and (non-)hematologic toxicity have been observed.

Massive mediastinal involvement in stage I-II Hodgkin's disease: response to combined modality treatment.

Thirty-seven patients with stage I-II Hodgkin's disease and massive mediastinal involvement, observed between June 1981 and November 1989, underwent combined modality treatment. This treatment included: 3 cycles of mechlorethamine, vincristine, procarbazine, and prednisone followed by mantle-field irradiation, and subsequently by 3 additional cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine. Thirty-five (95%) patients achieved complete responses and only 2 (5%) had partial responses. All the complete responders are living and relapse-free at a median follow-up of 62 months; no major toxic reactions were recorded. These data suggest, as did those of other studies, that combined modality therapy is superior to either radiotherapy or chemotherapy alone for patients in stage I-II with bulky disease, especially in the mediastinum. In fact, in these particular patients, if adequately treated with a combination of chemotherapy and radiotherapy, the role of massive mediastinal involvement as a poor prognostic factor appears to be less significant.

Cryptococcal meningitis and intracranial tuberculoma in a patient with Waldenstrom's macroglobulinemia treated with fludarabine.

We report a patient with Waldenstrom's Macroglobulinemia who presented with cryptococcal meningitis followed by an intracranial tuberculoma during the 18 months period after termination of cytotoxic therapy with Fludarabine. Opportunistic infections due to intracellular organisms are extremely rare in the course of this malignancy and we review the predisposing factors of these infectious entities.

Epirubicin plus medroxyprogesterone as second-line treatment of advanced prostatic cancer. A study by the Italian Trials in Medical Oncology Group.

The evaluation of drug efficacy in patients with advanced prostatic cancer who have progressed to hormonal therapy is difficult, although palliation of the pain related to bone involvement still represents an important endpoint. In this study, epirubicin (EpiADM) plus medroxyprogesterone acetate (MPA) were given to advanced prostatic cancer patients with symptomatic bone involvement who had progressed to hormonal therapy. EpiADM was administered at a dose of 30 mg/m2 i.v. weekly and MPA at a daily dose of 1,000 mg p.o. for the first month and 500 mg thereafter. Fifty-four patients entered the trial, all of whom were evaluable. Amelioration of pain and a > or = 50% reduction in analgesic intake were observed in 52% of cases, with a mean duration of 4 months. Of the 28 responsive patients, 26 had already received two lines of hormonal therapy or were resistant to first-line therapy. Of the 23 patients with measurable lesions, 6 obtained a > or = 50% tumor shrinkage at these sites. The treatment was well tolerated, and no cardiac toxicity was observed up to a total cumulative EpiADM dose of 660 mg/m2. In conclusion, this regimen seems to have a palliative effect in patients with advanced prostatic cancer who have progressed to hormonal therapy, and it is feasible in an outpatient setting.

Randomised trial of gemcitabine versus flec regimen given intra-arterially for patients with unresectable pancreatic cancer.

Gemcitabine is considered the golden standard treatment for unresectable pancreatic adenocarcinoma. Intra-arte-rial drug administration had shown a deep rationale with some interesting results. In a multicenter phase III trial, we compared gemcitabine given weekly with a combination of 5-fluoruracil, leucovorin, epirubicin, carboplatin (FLEC) administered intra-arteriously as first-line therapy in unresectable pancreatic adenocarcinoma. Patients were randomly assigned to receive gemcitabine at a dose of 1,000 mg/m2 over 30 minutes intravenously weekly for 7 weeks, followed by 1 week of rest, then weekly for 3 weeks every 4 weeks or 5-fluoruracil 1,000 mg/m2, leucovorin 100 mg/m2, epirubicin 60 mg/m2, carboplatin 300 mg/m2 infused bolus intra-arteriously at three-weekly interval for 3 times. The primary end point was overall survival, while time to treatment failure, response rate, clinical benefit response were secondary endpoints. Sixty-seven patients were randomly allocated gemcitabine and 71 were allocated FLEC intra-arterially. Patients treated with FLEC lived for significantly longer than patients on gemcitabine (p=.036). Survival at 1 year was increased from 21% in the gemcitabine group to 35% in the FLEC group. Median survival was 7.9 months in the FLEC group and 5.8 months in the gemcitabine group. Median time to treatment failure was longer with FLEC (5.3 vs 4.2 months for FLEC vs gemcitabine respectively; p=.013). Clinical benefit was similar in both groups (17.9% for gemcitabine and 26.7% for FLEC; p=NS). CT-scan partial response was similar in both group (5.9% for gemcitabine and 14% for FLEC; p=NS). Toxicity profiles were different. Compared with gemcitabine, FLEC regimen given intra-arteriously, improved survival in patient with unresectable pancreatic adenocarcinoma.

Gastrointestinal autonomic nerve tumor: case report and review of the literature.

Gastrointestinal autonomic nerve (GAN) tumor is an uncommon specialized form of gastrointestinal stromal tumor (GIST). We report the case of a 46-year-old man affected by this tumor. The neoplasm arose from the sigmoid colon. The patient underwent surgery but eight months later an omental relapse occurred. A second laparotomy was successfully performed and the patient is free of disease at 21 months of follow-up. To our knowledge this is the first case of a large bowel GAN tumor described in the literature.

Primary non-Hodgkin lymphomas of the gastrointestinal tract: analysis of 41 cases.

Forty-one patients suffering from primary non-Hodgkin lymphomas of the digestive tract have been observed over a period of 15 years. The primary sites were: the stomach in 27 cases, the small bowel in 8, the ileocecal region in 5, and the mesentery in 1. Patients were staged according to the modified Ann Arbor staging system proposed by Mushoff (20). Four kinds of management were employed: 1) surgery alone; 2) surgery and radiotherapy; 3) surgery, radiotherapy and chemotherapy; 4) surgery and chemotherapy. One patient was treated by chemotherapy alone. Radiotherapy was administered postoperatively and chemotherapy after or during radiotherapy. Generally, 2 opposed fields largely encompassing the tumor area and lomboaortic nodes if necessary, up to 25-30 Gy to the midline, were employed, with a booster dose up to 40-45 Gy to the involved area. Total abdominal irradiation was never employed. No clear difference emerged in survival rate nor in relapse-free survival among the four subgroups, but patients who underwent complete resection fared better than incompletely resected patients. However, these two subgroups were not homogeneous. A clear difference in survival rate did not emerge between patients treated or not with postoperative chemotherapy, whereas patients who relapsed after complete remission or those who never had complete remission had a poor prognosis.

Breast metastasis from gastric signet ring cell carcinoma, mimicking inflammatory carcinoma. A case report.

We report a case of breast metastasis of signet ring cell gastric cancer clinically presented as a primary inflammatory carcinoma. Metastases to the breast are uncommon; review of the literature demonstrated only 300 cases. The clinical and radiographic features of the metastatic lesion were unlike those reported in the literature. Although a primary signet ring cell breast carcinoma were described, the pathologic patterns of the breast lesion, here reported, lead us to conclude this was a metastasis and not another primary tumor.

Carboplatin and etoposide in an out-patient schedule for the palliation of advanced non-small-cell lung cancer.

AIMS AND BACKGROUND: In Western countries, non-small-cell lung cancer is the most important cause of cancer-related death. To date, medical treatment for advanced stages remains of a palliative nature. METHODS: Forty-four patients with advanced non-small-cell lung cancer were treated in a phase II study with carboplatin and etoposide (each at 60 mg/m2 daily) in a 5-day schedule. Among 44 patients, 18 (40%) had stage IIIB disease and 26 (60%) had stage IV disease. RESULTS: Treatment was well tolerated, and the only significant side effect was alopecia. The overall response rate was 27% with 2 complete remissions; median survival time was 10.4 months. One of the 2 patients achieving a complete remission was still alive and disease free at 36 months from the start of therapy. An improvement of performance status was observed in 22 patients (50%). CONCLUSIONS: The combinations of carboplatin and etoposide using this schedule appears to be well tolerated and has some activity in the palliation of advanced non-small-cell lung cancer.

Intra-arterial hepatic carboplatin-based chemotherapy for ocular melanoma metastatic to the liver. Report of a phase II study.

AIMS AND BACKGROUND: ocular melanoma tends to metastasize to the liver, sparing for a long time the rest of the organism. Therefore, a regional treatment is especially indicated. METHODS: eight patients with ocular melanoma metastatic to the liver were treated with intra-arterial hepatic carboplatin-based chemotherapy at the dose of 300 mg/m2 once every two weeks at an out-patient clinic. All the patients were submitted to laparotomy with surgical implantation of an arterial port device through the gastroduodenal artery. RESULTS: the overall response rate was 38% with a median survival time of 15 months. The regimen was well tolerated and the principle toxicity was myelosuppression; any instance of hepatic and/or cholangitic damage was reported. CONCLUSIONS: Carboplatin seems suitable for intra-arterial hepatic chemotherapy and active in ocular melanoma metastatic to the liver.
