RESUMO

BACKGROUND: Treatment with nab-paclitaxel plus gemcitabine increases survival in patients with metastatic pancreatic cancer. However, the assessment of treatment efficacy and safety in non-selected patients in a real-life setting may provide useful information to support decision-making processes in routine practice. METHODS: Retrospective, multicenter study including patients with metastatic pancreatic cancer, who started first-line treatment with nab-paclitaxel plus gemcitabine between December 2013 and June 2015 according to routine clinical practice. In addition to describing the treatment pattern, overall survival (OS) and progression-free survival (PFS) were assessed for the total sample and the exploratory subgroups based on the treatment and patients' clinical characteristics. RESULTS: All 210 eligible patients had a median age of 65.0 years (range 37-81). Metastatic pancreatic adenocarcinoma was recurrent in 46 (21.9%) patients and de novo in 164 (78.1%); 38 (18%) patients had a biliary stent. At baseline, 33 (18.1%) patients had an ECOG performance status ≥2. Patients received a median of four cycles of treatment (range 1-21), with a median duration of 3.5 months; 137 (65.2%) patients had a dose reduction of nab-paclitaxel and/or gemcitabine during treatment, and 33 (17.2%) discontinued treatment due to toxicity. Relative dose intensity (RDI) for nab-paclitaxel, gemcitabine, and the combined treatment was 66.7%. Median OS was 7.2 months (95% CI 6.0-8.5), and median PFS was 5.0 months (95% CI 4.3-5.9); 50 patients achieved either a partial or complete response (ORR 24.6%). OS was influenced by baseline ECOG PS, NLR and CA 19.9, but not by age ≥ 70 years and/or the presence of hepatobiliary stent or RDI < 85%. All included variables, computed as dichotomous, showed a significant contribution to the Cox regression model to build a nomogram for predicting survival in these patients: baseline ECOG 0-1 vs. 2-3 (p = 0.030), baseline NLR > 3 vs. ≤ 3 (p = 0.043), and baseline CA 19.9 > 37 U/mL vs. ≤37 U/mL (p = 0.004). CONCLUSIONS: Nab-Paclitaxel plus gemcitabine remain effective in a real-life setting, despite the high burden of dose reductions and poorer performance of these patients. A nomogram to predict survival using baseline ECOG performance status, NLR and CA 19.9 is proposed.

RESUMO

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.

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

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.

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.
