RESUMO

PURPOSE: 5-Fluorouracil/leucovorin, oxaliplatin, irinotecan (FOLFOXIRI) plus bevacizumab is more effective than doublets plus bevacizumab as first-line therapy for metastatic colorectal cancer, but is not widely used because of concerns about toxicity and lack of predictive biomarkers. This study was designed to explore the role of circulating tumour cell (CTC) count as a biomarker to select patients for therapy with FOLFOXIRI-bevacizumab. PATIENTS AND METHODS: VISNÚ-1 was a multicentre, open-label, randomised, phase III study in patients with previously untreated, unresectable, metastatic colorectal carcinoma and ≥3 CTC/7.5 mL blood. Patients received bevacizumab 5 mg/kg plus FOLFOXIRI (irinotecan 165 mg/m2, oxaliplatin 85 mg/m2, leucovorin 400 mg/m2 and 5-fluorouracil 3200 mg/m2) or FOLFOX (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil 400 mg/m2 then 2400 mg/m2) by intravenous administration every 2 weeks. The primary outcome was progression-free survival (PFS). RESULTS: The intention-to-treat population comprised 349 patients (FOLFOXIRI-bevacizumab, n=172; FOLFOX-bevacizumab, n=177). Median PFS was 12.4 months (95% CI 11.2 to 14.0) with FOLFOXIRI bevacizumab and 9.3 months (95% CI 8.5 to 10.7) with FOLFOX-bevacizumab (stratified HR, 0.64; 95% CI 0.49 to 0.82; p=0.0006). Grade≥3 adverse events were more common with FOLFOXIRI-bevacizumab 85.3% vs 75.1% with FOLFOX-bevacizumab (p=0.0178). Treatment-related deaths occurred in 8 (4.7%) and 6 (3.4%) patients, respectively. CONCLUSIONS: First-line FOLFOXIRI-bevacizumab significantly improved PFS compared with FOLFOX-bevacizumab in patients with metastatic colorectal cancer and ≥3 CTCs at baseline, which indicate a poor prognosis. CTC count may be a useful non-invasive biomarker to assist with the selection of patients for intensive first-line therapy.

RESUMO

BACKGROUND: We previously reported a 35% overall response rate (ORR) with biweekly 5-fluorouracil (5-FU) continuous infusion (TTD [Spanish Cooperative Group for Digestive Tumour Therapy] schedule) plus irinotecan as first-line therapy in elderly patients with metastatic colorectal cancer (mCRC). The present study also was carried out in elderly patients to determine the efficacy and safety of the same 5-FU schedule plus oxaliplatin. PATIENTS AND METHODS: Patients (aged ≥72 years old) with mCRC, measurable disease, ECOG (Eastern Cooperative Oncology Group) ≤2, and no prior treatment were treated with oxaliplatin 85 mg/m(2) plus 5-FU 3000 mg/m(2) as a 48-hour infusion every 2 weeks. RESULTS: The study included 134 patients, of whom, 129 were eligible. The main comorbidities were hypertension (44%), diabetes (17%), and chronic obstructive pulmonary disease (11%). The ORR and disease control rate (ORR plus stable disease) were 52% and 80%, respectively. With a median follow-up of 14 months, the median progression-free survival and overall survival were 9.1 and 16.3 months, respectively. The most frequent grade 3/4 adverse events included neutropenia (16%), diarrhea (11%), and grade 3 neurotoxicity (18%). No correlation was found between efficacy or safety and comorbidities. CONCLUSIONS: To our knowledge, this is the largest phase II prospective study in elderly patients with mCRC. The observed efficacy and safety of this schedule compared favorably with those reported in this population, including regimens with monoclonal antibodies.

RESUMO

UNLABELLED: Objective. We conducted this phase II trial to evaluate the efficacy and toxicity of the sequential nonplatinum combination chemotherapy consisting of gemcitabine (GEM) and vinorelbine (VNR) followed by weekly docetaxel (DOC) in patients with advanced non-small-cell lung cancer (NSCLC). Patients and methods. ELIGIBILITY CRITERIA: stage IV NSCLC, Performance status =/< 2, adequate renal, hepatic and bone marrow function. Treatment consisted on: VNR 25 mg/m(2) plus gemcitabine 1000 mg/m(2), on days 1 and 8 of each 21-day cycle, followed by docetaxel 36 mg/m(2) weekly until progression or unacceptable toxicity. Results. 21 stage IV patients were enrolled. All patients are evaluable for treatment response and toxicity profile. The mean age of the patients was 63 years (range: 51 to 72) with 18 (86%) males and 3 (14%) females. Histology types were: adenocarcinoma in 8 patients (38%), large cell carcinoma in 1 patients (5%) and squamous cell carcinoma in 12 patients (57%). The majority of the patients had and ECOG PS of 1. Eight patients (38%) did not complete six cycles of gemcitabine-navelbine. The median number of cycles of gemcitabine-navelbine was 4 (range 2-6) Of the 13 patients (61%) who completed six cycles of gemcitabine-navelbine, all of them went on to receive weekly docetaxel and received at least 3 cycles, with a median number of 8 cycles (range 3- 16). The overall response rate was 33%. Respect survival, the minimum follow-up was 6 months (range, 6-25 months). The median survival time (MST) was 7.9 months, and the 1-year survival was 30%, and the median progression-free survival was 4.7 months. Toxicity was mild, well tolerated and mostly hematologic. In the GEM/VNR cycle, grade 3/4 neutropenia occurred in 14%, two patients with febrile neutropenia. Grade 3 anaemia in 1 patients (5%) and grade 3 thrombocytopenia in 1 patient (5%). Nonhematologic toxicity was also mild: 1 patient with Grade 3 skin toxicity with docetaxel, 1 patient with grade 3 infection, 2 patients with grade 3 astenia and 1 patient with a mild allergic reaction postchemotherapy treatment with docetaxel. Conclusion. The sequential triplet nonplatinum chemotherapy consisted of GEM/VNR followed by weekly DOC is active and can be administered safely in advanced NSCLC. Our results are similar with other sequential regimens and did not represent a significant improvement in the treatment of this disease.

Backbround. In this Phase I/II trial, the maximumtolerateddose (MTD) and activity of cisplatin plusvinorelbine (VRL) administered in continuous infusionas first-line treatment of advanced non smallcell lung cancer (NSCLC) was determined in 12consecutive chemotherapy-naive patients with advancedNSCLC.Patients and methods. The dose of cisplatin was100 mg/m2 in all patients, and vinorelbine was administeredas an initial intravenous (iv) bolus of 8mg/m2 on day 1 followed by a 4-day continuous ivinfusion at 4 different 24 h dose levels (DLs) to berepeated every 21 days. All 12 patients (47 cycles)were evaluable for response and toxicity.Results. The MTD was 8 mg/m2 bolus followed by acontinuous iv infusion of 8 mg/m2 per day over 4days. The dose limiting toxicities (DLT) were febrileneutropenia in 4 patients and grade 3 mucositis in 1patient. There was less neuro-toxicity and comparedto the weekly bolus scheme. There was nosignificant cumulative toxicity after 3 cycles. Partialresponses were observed in 6 patients; an overall responserate of 50% (95% CI: 30-65%). Median time toprogression was 5,5 months (95% CI: 1,5-11 months)and median survival was 11 months (95% CI: 5-20months).Conclusions. The results demonstrate that, in thissetting of first-line treatment of NSCLC, cisplatinplus vinorelbine at 8 mg/m2 bolus followed by acontinuous infusion of 8 mg/m2 per day over 4 daysis the recommended schedule. Further trials wouldbe useful to establish activity of this combination

RESUMO

Renal cell carcinoma is an uncommon tumor in adults. Metastasis in the nasal fossa is rare, and can become apparent as a result of repeated epistaxis. We report a patient with renal cell carcinoma presenting with epistaxis secondary to a metastasis in the right nasal fossa. The primary tumor was treated with nephrectomy and the nasal fossa metastasis was treated successfully with embolization, chemoimmunotherapy, surgery, and radiotherapy. The presence of repeated epistaxis may very occasionally be the first symptom of renal cell carcinoma, and systemic treatment combined with local treatment may enable adequate control of the disease.

RESUMO

Bronchiolitis obliterans organizing pneumonia (BOOP) is a clinicopathologic syndrome with characteristic features. The diagnosis of BOOP requires the presence of a combination of pathological, clinical, and radiological features. We report the case of a lung cancer patient with bronquiloalveolar carcinoma (BAC) presenting with BOOP after chemotherapy with docetaxel and gemcitabine producing severe respiratory insufficiency, and simulating a progression of the tumor.

RESUMO

Primary signet-ring cell carcinoma of the prostate is infrequent and even more so as secondary spread of this pathologic sub-type to the prostate. We describe the sixth reported case with a diagnosis of a secondary signet-ring cell tumour of the prostate secondary to a gastric cancer. Five years post-gastrectomy to resect signet-ring cell carcinoma, we detected a secondary intra-prostatic spread with urinary tract obstruction. The physical appearance of the tumour cells was similar to that of the previously-resected signet-cell carcinoma of the stomach. There were no metastases in other sites and the patient was treated with radiotherapy. When confronted with intra-prostatic signet-ring cell adenocarcinoma it is necessary to distinguish between primary and secondary aetiology since this would reflect in the choice of treatment and prognosis.

RESUMO

BACKGROUND: In this phase I/II trial, the maximum tolerated dose (MTD) and activity of vinorelbine administered in continuous infusion as first-line treatment for advanced non-small-cell lung cancer (NSCLC) was determined in 25 consecutive chemotherapy-naive patients with advanced NSCLC. PATIENTS AND METHODS: Vinorelbine was administered as an initial intravenous (I.V.) bolus of 8 mg/m(2) on day 1 followed by a 4-day continuous I.V. infusion at 5 different 24-hour dose levels to be repeated every 21 days. All 25 patients (159 cycles) were evaluable for response. The MTD was 8 mg/m(2) bolus followed by a continuous I.V. infusion of 11 mg/m(2) per day over 4 days. RESULTS: The dose-limiting toxicities were febrile neutropenia in 6 patients and grade 3 mucositis in 2 patients. There was less neurotoxicity and constipation and more mucositis compared with the weekly bolus scheme. There was no significant cumulative toxicity after 3 cycles. Treatment responses were observed in 6 patients: 1 complete response and 5 partial responses. The overall response rate was 24% (95% confidence interval [CI], 8%-40%). Median time to progression was 4 months (95% CI, 2-11 months), and median survival was 6 months (95% CI, 2-18 months). CONCLUSION: The results demonstrate that, in this setting of first-line treatment of NSCLC, vinorelbine administered as an 8 mg/m(2) bolus followed by a continuous infusion of 11 mg/m(2) per day over 4 days is the recommended schedule. Further trials are necessary to establish activity and possible benefits of combination with other agents.
