Toxicity Associated with Capecitabine in Patients Suffering from Dihydropyrimidine Dehydrogenase Deficiency.

Dihydropyrimidine dehydrogenase (DPD) is a metabolic enzyme that is crucial in 5-fluorouracil (5-FU) degradation. A deficiency in it is associated with the occurrence of adverse events following fluoropyrimidine-based therapies. We describe a case of toxicity grade 5 after the administration of capecitabine and oxaliplatin in a patient with stage III colorectal cancer and DPD congenital deficiency, which was identified later. Several polymorphisms have been associated with the global toxicity of 5-FU; however, genetic tests are low in sensitivity and therefore they cannot as yet be used as prescreening techniques in clinical practice.

Gemcitabine and vinorelbine followed by weekly docetaxel in patients with advanced non-small-cell lung cancer: a phase II trial of sequential chemotherapy.

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

Solitary metastasis in a nasal fossa as the first manifestation of a renal carcinoma.

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.

Bronchiolitis obliterans organizing pneumonia simulating progression in bronchioloalveolar carcinoma.

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.

Secondary signet-ring cell tumour of the prostate derived from a primary gastric malignancy.

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.

Continuous-infusion vinorelbine for the treatment of advanced non-small-cell lung cancer: a phase I/II study.

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.

A panel discussion of controversies and challenges in the adjuvant treatment of colon cancer.

Current issues of adjuvant therapy for colon cancer concern the introduction of drugs other than fluorouracil-5/leucovorin (5-FU/LV), the benefits for stage II patients, the use of new primary endpoints and the influence of age on treatment benefits. These issues were addressed in a panel discussion and the conclusions were the following: FOLFOX4 is the first regimen that shows superiority over 5-FU/LV. The use of 3-year disease-free survival as primary endpoint could encourage the quicker adoption of improved therapeutic strategies into clinical practice. Available data suggest that there are some benefits for stage II patients, and the decision needs to be individualised for each patient. Further, therapeutic decisions based solely on the patient's age are inappropriate, and geriatric assessment tools will help in making this decision. This information would improve patient and physician understanding of the recent data regarding the potential benefits of adjuvant therapy.

A panel discussion of controversies and challenges in the adjuvant treatment of colon cancer

Las controversias actuales referentes al tratamiento adyuvante del cáncer de colon incluyen la introducción de fármacos más allá de 5-FU/LV, el beneficio que ofrece a los pacientes con estadio II, el uso de nuevas variables y la influencia de la edad sobre los beneficios del tratamiento. Estas controversias fueron discutidas en un panel de expertos y las conclusiones fueron las siguientes: FOLFOX4 es el primer régimen que ha demostrado superioridad frente a 5-FU/LV. El uso de la supervivencia libre de enfermedad a 3 años como variable principal de los estudios podrá permitir una adopción más rápida de estrategias terapéuticas. Los datos disponibles sugieren que existe beneficio para los pacientes con estadio II, y la decisión terapéutica debe ser individualizada. Finalmente, también se llegó a la conclusión de que las decisiones basadas únicamente en la edad no son apropiadas, y las herramientas de valoración geriátrica servirán de apoyo. Esta información puede mejorar el entendimiento de pacientes y médicos acerca de los datos recientes relativos a los beneficios del tratamiento adyuvante
