RESUMEN

(1) Background: Uveal melanoma (UM) is a common malignant intraocular tumor that presents with significant genetic differences to cutaneous melanoma and has a high genetic burden in terms of prognosis. (2) Methods: A systematic literature search of several repositories on uveal melanoma diagnosis, prognosis, molecular analysis, and treatment was conducted. (3) Results: Recent genetic understanding of oncogene-initiation mutations in GNAQ, GNA11, PLCB4, and CYSLTR2 and secondary progression drivers of BAP1 inactivation and SF3B1 and EIF1AX mutations offers an appealing explanation to the high prognostic impact of adding genetic profiling to clinical UM classification. Genetic information could help better explain peculiarities in uveal melanoma, such as the low long-term survival despite effective primary tumor treatment, the overwhelming propensity to metastasize to the liver, and possibly therapeutic behaviors. (4) Conclusions: Understanding of uveal melanoma has improved step-by-step from histopathology to clinical classification to more recent genetic understanding of oncogenic initiation and progression.

RESUMEN

(1) Background: Uveal malignant melanoma is the most common adult eye cancer and presents metabolic reprogramming that affects the tumoral microenvironment by altering the redox balance and producing oncometabolites. (2) Methods: The study prospectively evaluated patients undergoing enucleation surgery or stereotactic radiotherapy for uveal melanoma by following systemic oxidative-stress redox markers serum lipid peroxides, total albumin groups and total antioxidant levels (3) Results: Serum antioxidants and lipid peroxides were elevated from pre-treatment to longer-term follow-up. Antioxidants inversely correlated to lipid peroxides: higher in stereotactic radiosurgery patients pre/6/12/18 months post-treatment (p = 0.001-0.049) versus higher lipid peroxides in enucleation surgery patients pre/after/6 months post-treatment (p = 0.004-0.010). An increased variance in serum antioxidants was observed for enucleation surgery patients (p < 0.001), however enucleation did not increase mean serum antioxidants or albumin thiols; only lipid peroxides were increased post-enucleation (p < 0.001) and at 6-month follow-up (p = 0.029). Mean albumin thiols were increased for 18- and 24-month follow-ups (p = 0.017-0.022). Males who had enucleation surgery presented higher variance in serum determinations and overall higher lipid peroxides values pre/post-treatment and at the 18-month follow-up. (4) Conclusions: Initial oxidative stress-inducing events of surgical enucleation or stereotactic radiotherapy for uveal melanoma are followed by a longer-term inflammatory cascade gradually subsiding at later follow-ups.

RESUMEN

(1) Background: Ciliary body uveal melanoma is a rare subtype of uveal melanoma which comprises 3-5% of melanomas, an immunogenic cancer, and can present multifaceted initial clinical manifestations, masquerading as various ocular pathologies. Chronic lymphocytic leukemia (CLL) presents immunodeficiency and risk for the development of a secondary malignancy, with Bruton's tyrosine kinase inhibitor treatment having a mutagenic effect and a secondary anti-platelet aggregation effect. We present the case of a 65-year-old patient undergoing treatment for CLL with ibrutinib who presented with recurrent hyphema that masked an underlying, inferiorly situated, ciliary body uveal melanoma; (2) Methods: Retrospective case review; (3) Results: An ophthalmological examination together with imaging via mode B ultrasound and contrast-enhanced magnetic resonance imaging resulted in the clinical and imagistic diagnosis of a ciliary body uveal melanoma. A pathological examination of the enucleated eye confirmed the diagnosis. Postoperative tumoral reoccurrence was not detected for 1½ years, however, CLL immunosuppression worsened with admission for severe COVID-19 disease. (4) Conclusions: CLL patient screening for melanoma should also include detailed ophthalmological examinations, which could also include ultrasound ophthalmological imaging. The avoidance of uveal melanoma metastatic disease is paramount for patient survival. CLL manifests additional profound immunosuppression.

RESUMEN

BACKGROUND: Evidence-based antiemetic guidelines offer predominantly consistent recommendations for chemotherapy-induced nausea and vomiting (CINV) prophylaxis. However, studies suggest that adherence to these recommendations is suboptimal. We explored inconsistencies between clinical practice and guideline-recommended treatment with a registry evaluating the effect of guideline-consistent CINV prophylaxis (GCCP) on patient outcomes. PATIENTS AND METHODS: This was a prospective, non-interventional, multicentre study. The primary objective was to assess the overall (Days 1-5) complete response (CR: no emesis/no rescue use) rates in patients who received GCCP or guideline-inconsistent CINV prophylaxis (GICP) using diaries for 5 days following chemotherapy. Cycle 1 results are presented in patients who received either (1) anthracycline/cyclophosphamide (AC) highly emetogenic chemotherapy (HEC), non-AC HEC or carboplatin, with GCCP for all these groups consisting of prophylaxis with an NK1 receptor antagonist (RA), 5-HT3RA and dexamethasone prior to chemotherapy or (2) moderately emetogenic chemotherapy (MEC), with GCCP consisting of a 5-HT3RA and dexamethasone prior to chemotherapy as per MASCC/ESMO 2016 guidelines, in place at the time of the study. RESULTS: 1,089 patients were part of the cycle 1 efficacy evaluation. Overall GCCP was 23%. CR rates were significantly higher (P < 0.05) in patients receiving GCCP (62.2%) versus GICP (52.6%) in the overall population, as well as in the subsets of patients receiving AC/non-AC HEC (60.2% versus 47.8%), MEC (73.8% versus 57.8%) and in those non-naïve to the chemotherapy received (65.9% versus 53.8%). No impact on daily living due to CINV (FLIE assessment) was observed in 43.4% patients receiving GCCP versus 28.5% GICP (P < 0.001). CONCLUSION: Consistent with prior studies, GCCP was very low; a significant benefit of almost 10% improved prevention of CINV was observed with GCCP. As per MASCC/ESMO guidelines, such an absolute difference should be practice changing. Comprehensive multifaceted strategies are needed to achieve better adherence to antiemetic guidelines.

RESUMEN

BACKGROUND There are many causes of chronic colitis and diarrhea, including the effects of chemotherapy. Mutations in the UGT1A1 gene can be associated with increased toxicity from irinotecan-based chemotherapy. This report is of a case of delayed diagnosis of Clostridium difficile (C. difficile) colitis in a 48-year-old woman with a homozygous mutation of the UGT1A1 gene treated with chemotherapy for colorectal carcinoma. CASE REPORT A 48-year-old woman with a low-differentiated colonic adenocarcinoma was treated after surgery with irinotecan, 5 fluorouracil, and panitumumab and had a history of chronic and severe diarrhea. Genetic testing identified a mutation in the UGT1A1 gene associated with increased toxicity to irinotecan, and the EIA tests performed for evaluation of C. difficile toxins A and B showed repeatedly negative results. Replacement of irinotecan with oxaliplatin did not have significant therapeutic results, but these were achieved by the administration of active antibiotics against C. difficile (metronidazole, vancomycin, and fidaxomicin). CONCLUSIONS This report has shown that in complex cases where patients are treated with chemotherapy and have increased susceptibility to drug toxicity, chronic diarrhea may still have an infectious cause. Only when the diagnosis is correctly made can the patient be appropriately treated.

RESUMEN

Despite many advances in the latest period, lung cancer remains the cancer with the highest mortality. The latest developments concerning lung cancer treatment have changed the clinical practice by prolonging patient survival; however, unfortunately, there remains a high mortality rate firstly due to disease aggressivity and secondly through lack of early diagnosis and screening programs. Currently, researchers and clinicians are talking about personalized cancer treatment, and a complete diagnostic evaluation should consider, in addition to staging and histology, molecular aberrations, and genetics of the tumor tissue. The development of tyrosine kinase inhibitors (TKIs) has led to an improvement in survival for patients with EGFR mutations, this being the most studied driver mutation in adenocarcinoma; and at the same time an important predictive factor for patient outcome following the treatment with TKIs. Reseach must investigate the different TKI combination strategies in order to overcome resistance and to increase patient survival. Currently, there are ongoing clinical trials that will probably change the therapeutic approach for EGFR-mutated advanced or metastatic NSCLC patients.

RESUMEN

Introduction: In gastric cancer there are multiple local and general risk factors for the occurrence of postoperative fistulas. In the present study, we proposed to analyse the role of the preoperative nutritional state and nutritional therapy along with the disease stage, the age and the sex of patients in the occurrence of fistulas. Material and method: This retrospective study included 158 patients operated for gastric cancer in Surgery Department of Bucharest Oncology institute between January 2010 and December 2016 in which we analysed the incidence of anastomotic fistula according to the nutritional status, disease status, age and sex of the patients. Results: The global incidence of fistulas was of 11%, out of which 8 % were fistulas of the duodenal stump and 3.19% fistulas of the eso-jejunal anastomosis. Out of the 30 patients with weight loss and parenteral nutrition in the preop period, we had 4 fistulas (13%), and out of the 36 patients with weight loss and nutritional measures in the postop we had 5 fistulas (14%), also, out of the 24 patients with weight loss and without nutritional intervention, we had 5 fistulas (21%), finally, out of the 68 patients without weight loss we had fistulas in 4 patients (6%).. The incidence of fistulas was 5% in patients with stage I, II and III and 24% in stage IV patients. The distribution of fistulas according to the age of the patients showed a much higher incidence of fistulae in patients over 70 years old. Conclusions: The number of postoperative fistulas was higher in the advanced stages of the disease (p=0.027) and in patients over 70 years old (p=0.047) and the differences were statistically significant. The difference between the number of fistulae occurred in patients who had weight loss but did not receive nutritional support from those who received this support was not statistically significant (p 0.001).

RESUMEN

INTRODUCTION: Ramucirumab, a recombinant human immunoglobulin G1 monoclonal antibody receptor antagonist designed to block the ligand-binding site of vascular endothelial growth factor receptor-2 (VEGFR-2), was evaluated as second-line treatment in combination with docetaxel in patients with non-small-cell lung cancer in the REVEL trial (NCT01168973). Ramucirumab significantly improved overall survival (OS) and progression-free survival (PFS). We report age subgroup analysis results primarily on the basis of a 65-year cutoff. PATIENTS AND METHODS: Patients were randomized 1:1 to ramucirumab with docetaxel or placebo with docetaxel (n = 1253). Of these, 798 were younger than 65 years (ramucirumab, n = 391; control, n = 407) and 455 were 65 years or older (ramucirumab, n = 237; control, n = 218). Treatment comprised 21-day cycles of 75 mg/m2 docetaxel with 10 mg/kg ramucirumab or placebo. Prespecified age subgroup analyses were performed, including OS, PFS, and objective response rate. Quintiles age analysis was conducted to establish a relationship between efficacy and age. The Lung Cancer Symptom Scale (LCSS) measured quality of life outcomes. Safety was assessed according to adverse events (AEs). RESULTS: Patients younger than 65 years showed favorable OS outcomes with ramucirumab treatment (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.62-0.87; P < .001) and PFS (HR, 0.68; 95% CI, 0.59-0.79; P < .001). In patients 65 years or older, benefits of ramucirumab were not as evident; after model adjustment for prognostic factors, OS and PFS HRs were 0.96 (95% CI, 0.77-1.21; P = .04) and 0.87 (95% CI, 0.71-1.05; P = .03), respectively. Age analysis according to quintiles showed HRs favoring ramucirumab for all age groupings. LCSS scores and AEs did not considerably differ between age groups. CONCLUSION: In this subgroup analysis, true treatment effect differences on the basis of age have not been established, and treatment should not be deterred solely because of age.

RESUMEN

OBJECTIVES: First objective was better understanding of the indications of chemotherapy in elderly with advanced cancer, tolerability and toxicity of chemotherapy in this age group. The second objective was to define current practice in chemotherapy for elderly people with advanced cancer for a selected group of patients treated in Institute of Oncology Bucharest (IOB). MATERIALS AND METHODS: The study makes a clinical analysis of medical records of 27 patients from the archive of Institute of Oncology Bucharest treated by the same doctor. Patients were selected according to: age ≥ 65 years, ECOG performance status 0-1, normal blood counts and blood biochemistry, histological confirmation of the diagnosis of cancer, patients should received at least 3 cycles of chemotherapy. We extract characteristics of the patients to see if they were a homogeneous group of patients and to compare them with data from the literature. Overall survival was calculated by the Kaplan Meyer curve. RESULTS: 295 patients more then 65 years were treated in our site in 2 years 2011, 2012. 93 patients received chemotherapy and only 27 patients were enrolled in this study following inclusion criteria. Common sites of cancer were lung and breast. The most used cytostatics for lung cancer was gemcitabine and carboplatine and cyclophosphamide, metotrexat and 5 fluorouracil for breast cancer. Toxicity was mild with the prevalence of hematologic toxicity. Overall survival without taking into account the type of cancer was 27.7 month. CONCLUSIONS: For selected patients, chemotherapy was well tolerated and appears to prolong survival regardless of the location of cancer. The relatively small number of elderly patients who received chemotherapy is probably due to lack of compliance to treatment, the increased number of co-morbidities and evaluation of performance status only by the ECOG index known not to be good enough to establish the indication of chemotherapy.

RESUMEN

BACKGROUND: Ramucirumab is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. We aimed to assess efficacy and safety of treatment with docetaxel plus ramucirumab or placebo as second-line treatment for patients with stage IV non-small-cell-lung cancer (NSCLC) after platinum-based therapy. METHODS: In this multicentre, double-blind, randomised phase 3 trial (REVEL), we enrolled patients with squamous or non-squamous NSCLC who had progressed during or after a first-line platinum-based chemotherapy regimen. Patients were randomly allocated (1:1) with a centralised, interactive voice-response system (stratified by sex, region, performance status, and previous maintenance therapy [yes vs no]) to receive docetaxel 75 mg/m(2) and either ramucirumab (10 mg/kg) or placebo on day 1 of a 21 day cycle until disease progression, unacceptable toxicity, withdrawal, or death. The primary endpoint was overall survival in all patients allocated to treatment. We assessed adverse events according to treatment received. This study is registered with ClinicalTrials.gov, number NCT01168973. FINDINGS: Between Dec 3, 2010, and Jan 24, 2013, we screened 1825 patients, of whom 1253 patients were randomly allocated to treatment. Median overall survival was 10·5 months (IQR 5·1-21·2) for 628 patients allocated ramucirumab plus docetaxel and 9·1 months (4·2-18·0) for 625 patients who received placebo plus docetaxel (hazard ratio 0·86, 95% CI 0·75-0·98; p=0·023). Median progression-free survival was 4·5 months (IQR 2·3-8·3) for the ramucirumab group compared with 3·0 months (1·4-6·9) for the control group (0·76, 0·68-0·86; p<0·0001). We noted treatment-emergent adverse events in 613 (98%) of 627 patients in the ramucirumab safety population and 594 (95%) of 618 patients in the control safety population. The most common grade 3 or worse adverse events were neutropenia (306 patients [49%] in the ramucirumab group vs 246 [40%] in the control group), febrile neutropenia (100 [16%] vs 62 [10%]), fatigue (88 [14%] vs 65 [10%]), leucopenia (86 [14%] vs 77 [12%]), and hypertension (35 [6%] vs 13 [2%]). The numbers of deaths from adverse events (31 [5%] vs 35 [6%]) and grade 3 or worse pulmonary haemorrhage (eight [1%] vs eight [1%]) did not differ between groups. Toxicities were manageable with appropriate dose reductions and supportive care. INTERPRETATION: Ramucirumab plus docetaxel improves survival as second-line treatment of patients with stage IV NSCLC.

RESUMEN

BACKGROUND: Erlotinib, docetaxel, and pemetrexed are approved for the second-line treatment of non-small-cell lung cancer (NSCLC), but no head-to-head data from large clinical trials are available. We undertook the Tarceva In Treatment of Advanced NSCLC (TITAN) study to assess the efficacy and tolerability of second-line erlotinib versus chemotherapy in patients with refractory NSCLC. METHODS: TITAN was an international, randomised multicentre, open-label, phase 3 study that was done at 77 sites in 24 countries. Chemotherapy-naive patients with locally advanced, recurrent, or metastatic NSCLC received up to four cycles of first-line platinum doublet chemotherapy, after which patients with disease progression during or immediately after chemotherapy were offered enrolment into TITAN. Enrolled patients were randomly assigned (1:1) by a minimisation method to ensure balanced stratification, to receive erlotinib 150 mg/day or chemotherapy (standard docetaxel or pemetrexed regimens, at the treating investigators' discretion), until unacceptable toxicity, disease progression, or death. Patients were stratified by disease stage, Eastern Cooperative Oncology Group performance status, smoking history, and region of residence. The primary endpoint was overall survival in the intention-to-treat population. TITAN was halted prematurely because of slow recruitment. This study is registered with ClinicalTrials.gov, number NCT00556322. FINDINGS: Between April 10, 2006, and Feb 24, 2010, 2590 chemotherapy-naive patients were treated with first-line platinum doublet chemotherapy, of whom 424 had disease progression and were enrolled into TITAN. 203 patients were randomly assigned to receive erlotinib and 221 were assigned to receive chemotherapy. Median follow-up was 27·9 months (IQR 11·0-36·0) in the erlotinib group and 24·8 months (12·1-41·6) in the chemotherapy group. Median overall survival was 5·3 months (95% CI 4·0-6·0) with erlotinib and 5·5 months (4·4-7·1) with chemotherapy (hazard ratio [HR] 0·96, 95% CI 0·78-1·19; log-rank p=0·73). The adverse-event profile of each group was in line with previous studies. Rash (98/196 [50%] in the erlotinib group vs 10/213 [5%] in the chemotherapy group for all grades; nine [5%] vs none for grade 3 or 4) and diarrhoea (36 [18%] vs four [2%] for all grades; five [3%] vs none for grade 3 or 4) were the most common treatment-related adverse events with erlotinib, whereas alopecia (none vs 23 [11%] for all grades; none vs one [<1%] for grade 3/4) was the most common treatment-related adverse event with chemotherapy. INTERPRETATION: No significant differences in efficacy were noted between patients treated with erlotinib and those treated with docetaxel or pemetrexed. Since the toxicity profiles of erlotinib and chemotherapy differ, second-line treatment decisions should take into account patient preference and specific toxicity risk profiles.

RESUMEN

BACKGROUND: Third-generation platinum-based combinations are established as first-line treatment for advanced non-small cell lung cancer (NSCLC). Non-platinum regimens could be an alternative if they show similar efficacy with better tolerability. This randomized phase II trial compared the objective tumor response rate (ORR) of sequential gemcitabine plus vinorelbine followed by gemcitabine plus ifosfamide versus gemcitabine plus cisplatin. Secondary objectives included time to disease progression (TTP), overall survival and toxicity. METHODS: Chemo-naive patients with stages III and IV NSCLC and Karnofsky performance status >70 were assigned to receive either (a) gemcitabine 1000mg/m(2) plus vinorelbine 25mg/m(2) on days 1 and 8 for 2 cycles, followed by gemcitabine 1000mg/m(2) on days 1 and 8 plus ifosfamide 2000mg/m(2) on day 1 (GV-GI arm) for 2 cycles or (b) gemcitabine 1250mg/m(2) on days 1 and 8 with cisplatin 70mg/m(2) on day 1 (GC arm) for 4 cycles. RESULTS: Between July 2001 and January 2003, 102 patients were enrolled (50 on the GV-GI arm and 52 on the GC arm). Patient characteristics were balanced between arms (GV-GI arm: median age 59 years, 84% male, 22 stage IIIB, 24 stage IV, 4 stage IIIA; GC arm: median age 56 years, 87% male, 27 stage IIIB, 23 stage IV, 2 stage IIIA). Of the 101 patients evaluable for response, ORR was significantly higher on the GC arm than on the GV-GI arm (25% versus 6%, respectively; p=0.007). No complete responses occurred. TTP was longer on the GC arm than on the GV-GI arm (median 135 and 79 days, respectively), although this difference was not statistically significant (p=0.065). Survival was not significantly different between the arms (median 293 and 197 days, respectively; p=0.16). Although significantly more thrombocytopenia was reported on the GC arm (22% and 4%, respectively; p=0.02), it did not lead to more transfusions (15 transfusions in 5 patients versus 14 transfusions in 6 patients, respectively). There was no significant difference in other safety parameters between treatment arms. CONCLUSIONS: GC appears to produce better response in advanced NSCLC than GV-GI, with a trend towards longer TTP. Except for more thrombocytopenia with GC, similar toxicity profiles were observed.

RESUMEN

PURPOSE: The combination of Gemcitabine (GEM)/carboplatin (CBDCA) has demonstrated activity in the treatment of stage III and IV non-small-cell lung cancer (NSCLC). This phase III randomized trial compared the response rate, survival rate, and toxicity of the combination of GEM plus CBDCA with the combination of VLB plus CDDP. METHODS: Chemonaïve patients with advanced or metastatic NSCLC were enrolled in the study. Pts were randomized by coin method to receive either cisplatin (CDDP) 70 mg/m(2) on day 1 plus vinblastine (VLB) 6 mg/m(2) on days 1 and 8 (arm A) or gemcitabine 1000 mg/m(2) on days 1 and 8 plus carboplatin 300 mg/m(2) on day 1 (arm B). Both regimens were administered on a 21-day course. RESULTS: A total of 198 patients (99 pts each in arms A and B) were enrolled in the study between July 1997 and April 2000. All pts had an ECOG performance status < or=2. Patients had a median age of 58 years (range, 49-67) in arm A and 59 years (range, 49-69) in arm B. In arm A, there were 15 partial responders (PR), for an overall response rate (ORR) of 15%, compared with three complete responders (CR) and 24 PR, for an ORR of 27% (P<0.05), in arm B. Mean survival times were 7.9 months (95% CI, 7.1-8.0) in arm A and 11.6 months (95% CI, 10.0-13.0) in arm B. One-year survival rates for arms A and B, respectively, were 13 and 36%. Numbers of pts with WHO grad 3/4 hematologic and non-hematologic toxicity in arms A/B were leukopenia 0/2, thrombocytopenia 0/2, alopecia 46/33, neurotoxicity 2/1, and asthenia 35/42. CONCLUSION: The GEM/CBDCA combination showed a higher therapeutic response, an improved 1-year survival, and a similar toxicity profile compared with the VLB/CDDP combination.
