RESUMEN

PURPOSE: Triple-negative breast cancer (TNBC) represents a subtype of breast cancer which lacks the expression of oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2): TNBC accounts for approximately 20% of newly diagnosed breast cancers and is associated with younger age at diagnosis, greater recurrence risk and shorter survival time. Therapeutic options are very scarce. Aim of the present analysis is to provide further insights into the clinical activity of metronomic chemotherapy (mCHT), in a real-life setting. METHODS: We used data included in the VICTOR-6 study for the present analysis. VICTOR-6 is an Italian multicentre retrospective cohort study, which collected data of metastatic breast cancer (MBC) patients who have received mCHT between 2011 and 2016. Amongst the 584 patients included in the study, 97 were triple negative. In 40.2% of the TNBC patients, mCHT was the first chemotherapy treatment, whereas 32.9% had received 2 or more lines of treatment for the metastatic disease. 45.4% out of 97 TNBC patients received a vinorelbine (VRL)-based regimen, which resulted in the most used type of mCHT, followed by cyclophosphamide (CTX)-based regimens (30.9%) and capecitabine (CAPE)-based combinations (22.7%). RESULTS: Overall response rate (ORR) and disease control rate (DCR) were 17.5% and 64.9%, respectively. Median progression free survival (PFS) and overall survival (OS) were 6.0 months (95% CI: 4.9-7.2) and 12.1 months (95% CI: 9.6-16.7). Median PFS was 6.9 months for CAPE-based regimens (95% CI: 5.0-18.4), 6.1 months (95% CI: 4.0-8.9) for CTX-based and 5.3 months (95% CI: 4.1-9.5) for VRL-based ones. Median OS was 18.2 months (95% CI: 9.1-NE) for CAPE-based regimens and 11.8 months for VRL- (95% CI: 9.3-16.7 and CTX-based ones (95%CI: 8.7-52.8). Tumour response, PFS and OS decreased proportionally in later lines. CONCLUSION: This analysis represents the largest series of TNBC patients treated with mCHT in a real-life setting and provides further insights into the advantages of using this strategy even in this poor prognosis subpopulation.

RESUMEN

Nowadays, treatment of metastatic breast cancer (MBC) has been enriched with novel therapeutical strategies. Metronomic chemotherapy (mCHT) is a continuous and frequent administration of chemotherapy at a lower dose and so whit less toxicity. Thus, this strategy could be attractive for elderly MBC patients. Aim of this analysis is to provide insights into mCHT's activity in a real-life setting of elderly MBC patients. Data of patients ≥ 75 years old included in VICTOR-6 study were analyzed. VICTOR-6 is a multicentre, Italian, retrospective study, which collected data on mCHT in MBC patients treated between 2011 and 2016. A total of 112 patients were included. At the beginning of mCHT, median age was 81 years (75-98) and in 33% of the patients mCHT was the first line choice. Overall Response Rate (ORR) and Disease Control Rate (DCR) were 27.9% and 79.3%, respectively. Median PFS ranged between 7.6 and 9.1 months, OS between 14.1 and 18.5 months. The most relevant toxicity was the hematological one (24.1%); severe toxicity (grade 3-4) ranged from 0.9% for skin toxicity up to 8% for hematologic one. This is a large study about mCHT in elderly MBC patients, providing insights to be further investigated in this subgroup of frail patients.

RESUMEN

BACKGROUND: Previous studies investigating the prognostic role of mucinous histology of colorectal cancer produced conflicting results. This retrospective analysis was carried out in order to explore whether mucinous adenocarcinoma (MC) is associated with a comparatively worse prognosis than that of nonmucinous adenocarcinoma (NMC) for patients undergoing curative resection for stage II and III colon cancer. PATIENTS AND METHODS: This study involved 1025 unselected patients who underwent curative surgery for sporadic colon cancer and follow-up procedures at six different oncology departments. RESULTS: MCs accounted for 17.4% (n=178) of tumours. Patients with MC had 5- and 8-year overall survival rates of 78.6% and 68.8%, respectively, compared with 72.3% and 63.8%, respectively, for patients with nonmucinous tumours. Multivariate analysis using the Cox proportional hazards model showed that the clinically significant prognostic factors were stage of disease and adjuvant chemotherapy. No statistically significant interaction between mucinous histology and adjuvant chemotherapy was found. CONCLUSIONS: For patients with stage II and III colon cancer who underwent curative surgery, mucinous histology has no significant correlation with prognosis compared with NMC. This retrospective analysis suggests a comparable benefit from adjuvant chemotherapy for MC compared with NMC.

RESUMEN

The objective of this study was to investigate the efficacy of first-line chemotherapy containing irinotecan and/or oxaliplatin in patients with advanced mucinous colorectal cancer. Prognostic factors associated with response rate and survival were identified using univariate and multivariate logistic and/or Cox proportional hazards analyses. The population included 255 patients, of whom 49 (19%) had mucinous and 206 (81%) had non-mucinous colorectal cancer. The overall response rates for mucinous and non-mucinous tumours were 18.4 (95% CI, 7.5-29.2%) and 49% (95% CI, 42.2-55.8%), respectively (P=0.0002). After a median follow-up of 45 months, median overall survival for the mucinous patients was 14.0 months compared with 23.4 months for the non-mucinous group (hazard ratio (HR), 1.74; CI 95%, 1.27-3.31; P=0.0034). After adjustment for significant features by multivariate Cox regression analysis, mucinous histology was associated with poor overall survival (HR, 1.593, 95% CI, 1.05-2.40; P=0.0267), together with performance status ECOG 2, number of metastatic sites > or =2, and peritoneal metastases. This retrospective analysis shows that patients with mucinous colorectal cancer have poor responsiveness to oxaliplatin/irinotecan-based first-line combination chemotherapy and an unfavourable prognosis compared with non-mucinous colorectal cancer patients.

RESUMEN

No established second-line chemotherapy is available for patients with advanced gastric cancer failing to respond or progressing to first-line chemotherapy. However, 20-40% of these patients commonly receive second-line chemotherapy. We evaluated the influence of clinico-pathologic factors on the survival of 175 advanced gastric cancer patients, who received second-line chemotherapy at three oncology departments. Univariate and multivariate analyses found five factors which were independently associated with poor overall survival: performance status 2 (hazard ratio (HR), 1.79; 95% CI, 1.16-2.77; P=0.008), haemoglobin 50 ng ml(-1) (HR, 1.86; 95% CI, 1.21-2.88; P=0.004), the presence of greater than or equal to three metastatic sites of disease (HR, 1.72; 95% CI, 1.16-2.53; P=0.006), and time-to-progression under first-line chemotherapy

RESUMEN

BACKGROUND: Elderly patients have been often excluded from or underrepresented in the study populations of combination chemotherapy trials. The primary end point of this study was to determine the response rate and the toxicity of the weekly oxaliplatin, 5-fluorouracil and folinic acid (OXALF) regimen in elderly patients with advanced gastric cancer. The secondary objective was to measure the time to disease progression and the survival time. METHODS: Chemotherapy-naive patients with advanced gastric cancer aged 70 or older were considered eligible for study entry. Patients received weekly oxaliplatin 40 mg/m2, fluorouracil 500 mg/m2 and folinic acid 250 mg/m2. All drugs were given intravenously on a day-1 schedule. RESULTS: A total of 42 elderly patients were enrolled. Median age was 73 years and all patients had metastatic disease. The response rate according to RECIST criteria was 45.2% (95% CIs: 30%-56%) with two complete responses, 17 partial responses, 13 stable diseases and 10 progressions, for an overall tumor rate control of 76.2% (32 patients). Toxicity was generally mild and only three patients discontinued treatment because of treatment related adverse events. The most common treatment-related grade 3/4 adverse events were fatigue (7.1%), diarrhoea (4.8%), mucositis (2.4%), neurotoxicity (2.4%) and neutropenia (4.8%). The median response duration was 5.3 months (95% CIs: 2.13 - 7.34), the median time to disease progression was 5.0 months (95% CIs: 3.75 - 6.25) and the median survival time was 9.0 months (95% CIs: 6.18 - 11.82). CONCLUSION: OXALF represents an active and well-tolerated treatment modality for elderly patients with locally advanced and metastatic gastric cancer.

RESUMEN

The usefulness of chemotherapy in patients with stage II disease continues to be debated. Biological prognostic factors may allow further insight into the optimal treatment strategy for patients with node-negative disease. Vascular endothelial growth factor (VEGF) seems to be essential for angiogenesis and for the growth of colorectal cancer. Recently, it was shown able to predict disease recurrence in patients with stage II colon cancer. Specimens of surgically resected colon cancer were immunostained for VEGF. Consecutive patients referred to the study institutions were considered eligible for this study. The main inclusion criteria were stage II tumor, sufficient tumor material, and adequate follow-up information. Analysis was performed on 121 patients. The recurrence rate in the patients with VEGF-positive tumors was 50% (18 of 36 patients), which was significantly higher than that observed in patients with VEGF-negative tumors [11.7% (10 of 85 patients); P = 0.001]. Also the degree of VEGF immunoreactivity was significantly higher in 28 relapsing patients compared with 93 disease-free patients (mean VEGF score, 2.84 0.38 versus 0.66 +/- 0.17; P = 0.0001). VEGF may be used in a clinical setting to identify patients at high risk for relapse who may benefit from adjuvant treatment including new therapeutic strategies such as monoclonal antibody neutralizing VEGF.

RESUMEN

Gastrointestinal cancers account for a large amount of human tumors. Surgery is the standard treatment for localized gastrointestinal cancer, but in a large number of patients, tumors are unresectable at time of diagnosis and even when resectable, survival is often poor. Current attempts to improve these results include the use of chemotherapy in the adjuvant setting, in the advanced disease, or as neoadjuvant treatment. However, less than half the patients respond to chemotherapeutic treatments, mostly reporting important side-effects. The identification of molecular markers, such as p53, thymidylate synthase, K-ras, and others, may provide an important tool for medical oncologists in defining subsets of patients with gastrointestinal cancers more suitable to benefit from chemotherapy or from experimental therapies. The relationship between the clinical outcome to anticancer drugs and molecular markers in gastrointestinal tumors has been reviewed. Available data are promising, but most of them arise from retrospective and small studies. Well designed, prospective trials are warranted to change the target approach from a general to an individual treatment strategy.

RESUMEN

The vascular endothelial growth factor (VEGF) plays a central role in promoting angiogenesis, and it is the target of innovative anti-cancer therapies. In colorectal carcinomas, differences in the VEGF expression have been found between the primary tumor and its metastases. We postulated that differences in the VEGF expression may also exist between liver and abdominal metastases from colon cancer. Consecutive colon cancer patients with liver or abdominal metastases were considered eligible for the study. Biopsies had to be performed before chemotherapy and the VEGF analysis were conducted through immunohistochemistry. The staining results were correlated to the metastatic pattern. The study population consisted of 41 patients with a metastatic site in the liver in 19 patients and the abdomen in 22 patients. A positive VEGF staining was found in 19 of the 41 metastatic samples (46%). Cases with positive VEGF expression were found more frequently in abdominal (15 out of 22 patients; 68%) than in liver metastases (4 out of 19 patients; 21%). Also, the degree of VEGF immunoreactivity was significantly higher in abdominal than in liver metastases. Evidence is supported that the VEGF expression may be different between colon cancer metastatic sites. The efficacy of anti-VEGF treatments may depend on the VEGF expression status, and this finding deserves further investigation.

RESUMEN

BACKGROUND: Loss of activity of tumor suppressor genes is considered a fundamental step in a genetic model of carcinogenesis. Altered expression of the p53 and the Deleted in Colon Cancer (DCC) proteins has been described in gastric cancer and this event may have a role in the development of the disease. According to this hypothesis, we investigated the p53 and the DCC proteins expression in different stages of gastric carcinomas. METHODS: An immunohistochemical analysis for detection of p53 and DCC proteins expression was performed in tumor tissue samples of patients with UICC stage I and II gastric cancer. For the purpose of the analysis, the staining results were related to the pathologic data and compared between stage categories. RESULTS: Ninety-four cases of gastric cancer were analyzed. Disease stage categories were pT1N0 in 23 cases, pT2N0 in 20 cases, pT3N0 in 20 cases and pT1-3 with nodal involvement in 31 cases. Stage pT1-2N0 tumors maintained a positive DCC expression while it was abolished in pT3N0 tumors (p <.001). A significant higher proportion of patients with N2 nodal involvement showed DCC negative tumors. In muscular-invading tumors (pT2-3N0) the majority of cases showed p53 overexpression, whereas a significantly higher proportion of cases confined into the mucosa (pT1N0) showed p53 negative tumors. Also, a higher frequency of p53 overexpression was detected in cases with N1 and N2 metastatic lymph nodal involvement. CONCLUSIONS: Altered expression of both DCC and p53 proteins is detectable in gastric carcinomas. It seems that loss of wild-type p53 gene function and consequent p53 overexpression may be involved in early stages of tumor progression while DCC abnormalities are a late event.

RESUMEN

Knowledge of the prognostic role of biomarkers in colorectal cancer is limited and the routine determination for clinical practice is not warranted. However, for some of these markers, data are promising enough for further evaluation. This review addresses a comprehensive analysis of prognostic biomarkers in colorectal cancer. Data from published studies were collected and analyzed. A sufficient level of evidence suggests that DNA indexes, angiogenesis indicators and some genetic/biochemical markers identity prognostic differences in patients with early-stage colorectal cancer. High-risk patients could be the target for future adjuvant chemotherapy trials and one or more of these markers may identify prognostic subgroups with the same TNM stage category.

RESUMEN

INTRODUCTION: The prognosis of patients with T3N0M0 gastric cancer is still unfavourable and the role of adjuvant chemotherapy is unclear. We addressed this study to evaluate whether the analysis of the S-Phase Fraction (SPF) might have prognostic implications in serosa-positive, node-negative gastric cancer. MATERIALS AND METHODS: Specimens of resected gastric cancer were studied by flow cytometry for SPF analysis. Consecutive patients with stage pT3N0M0, adequate follow-up information and sufficient archival tumor tissue were considered eligible for the study. The tumor SPF indices were related to the timing of recurrences, the relapse rate and the disease-free survival of patients. RESULTS: The analysis was carried out on samples of 137 patients with surgically-resected, stage pT3N0M0 gastric cancer. SPF resulted high and low in 39% and 61% of cases, respectively. Fifty-seven patients relapsed (42%) and early recurrences (within 18 months after surgery) occurred more frequently among cases with high SPF (p < .03). Patients with high SPF tumors showed a worse relapse rate and disease-free survival than patients with low SPF tumors. (p < .005). CONCLUSION: The SPF analysis showed prognostic differences among patients with stage pT3N0M0 gastric cancer. These data may be of value in the planning of future adjuvant chemotherapy trials in gastric cancer.

RESUMEN

Forty patients of both sexes, aged between 25 and 65 years and suffering from gonarthrosis, took part in a controlled double-blind study of Proxen vs naproxen. Proxen was administered to 20 patients and the control drug to the other 20, in doses of 500 mg twice a day for 60 days. Both drugs demonstrated a good level of activity and tolerance. Proxen proved effective in 94% of the cases, while naproxen was effective in 80%.

RESUMEN

AIMS AND BACKGROUND: The phase II trial was designed to evaluate the activity of combined oxaliplatin (L-OHP), continuous infusion (CI) +/- bolus 5-fluorouracil (5FU) and levo-folinic acid (I-FA) in patients with metastatic colorectal cancer progressing after one or more lines of 5FU-based chemotherapy. PATIENTS AND METHODS: We designed two contemporary studies: in the former we enrolled patients previously treated with 1 line of chemotherapy, and in the latter, patients previously treated with 2, 3 and 4 lines. Seventy-six consecutive patients were enrolled: 45 received L-OHP (85 mg/m2 i.v. 2 h on day 1) + I-FA (100 mg/m2 i.v. 2 h on days 1 and 2) + 5FU i.v. bolus (400 mg/m2 days 1 and 2) + 5FU (600 mg/m2 CI 22 h days 1 and 2 (FOLFOX 4); 31 received L-OHP (100 mg/m2 i.v. 2 h on day 1) + I-FA (250 mg/m2 i.v. 2 h on days 1 and 2), followed by 5FU (1500 mg/m2 Cl 24 h days 1 and 2 (FOLFOX 2). The treatment was recycled every 2 weeks and continued until progression and/or unacceptable toxicity or patient preference. The primary end point was activity (tumor growth control [TGC]: partial response [PR] + stable disease [SD]); the secondary end points were time to progression (TTP), overall survival (OS) and toxicity. RESULTS: Forty-five patients in 2nd line (22 FOLFOX 4, 23 FOLFOX 2), 23 (17 FOLFOX 4, 6 FOLFOX 2) in 3rd, 4 in 4th and 1 in 5th line were assessable; 3 were lost to follow-up. In 15 patients (11 FOLFOX 4, 4 FOLFOX 2), disease involved the liver only. A total of 533 courses were administered with a range of 1-14 in FOLFOX4 and 1-12 in FOLFOX2; dose intensity was 92.85%, and the total dose of the administered L-OHP was 98.29%. As a 2nd line treatment, FOLFOX 4 achieved TGC in 72.8% of the patients (PR, 18.2%; SD, 54.6%), with a median TTP of 6 months and a median OS of 7 months, whereas in the FOLFOX 2 group these figures were 78.3% (PR 21.8%, SD 56.5%), and 5 and 9 months. As a 3rd line treatment, FOLFOX 4 produced TGC in 41.1% of patients (PR 23.5%, SD 17.6%), with a median TTP of 5 months and median OS of 7+ months, whereas FOLFOX 2 obtained respective values of 50% (PR 16.7%, SD 33.3%), 7 and 9 months. As a 4th line of treatment, TGC was achieved in 2 patients (1 PR, 1 SD); the patient in 5th line therapy obtained a SD. With "de Gramont" as the first-line regimen, patients assessable were 24 in FOLFOX 4 and 18 in FOLFOX 2. In the former population, TGC was 70.8% (PR 37.5%, SD 33.3%), with a TTP of 6 months and OS of 10 months, whereas with FOLFOX2 these values were 61.1% (PR 5.6%, SD 55.5), 5 and 7 months. In patients with liver involvement only, FOLFOX 4 obtained TGC in 63.6% of cases (with a TTP of 7 months and OS of 6+ months), FOLFOX 2 in 100% (with a TTP of 9.5 months and OS of 13.5+ months). Both schedules exhibited an acceptable toxicity: neurologic, hematologic and hepatic grade 3 side effects occurred in a limited number of patients, with a higher frequency in the FOLFOX 2 group. CONCLUSIONS: Treatment with L-OHP, CI +/- bolus 5FU and I-FA was well tolerated. The activity in terms of TGC was interesting and comparable with results reported in the literature for the standard treatment for 2nd line, i.e. irinotecan alone. Treatment was effective in 2nd line and in patients previously treated with more than two chemotherapy lines; in particular, treatment was active in patients with hepatic disease only. Although the two schedules seemed to achieve the same benefit with the same tolerance, we could not define from the study the better regime.

RESUMEN

The aim of our analysis was to assess retrospectively the effect on local relapse, overall survival (OS) and disease-free survival (DFS) of a limited or an extended lymphadenectomy in radically resected gastric cancer patients. This study was performed in order to identify a subgroup of patients possibly not benefiting from a therapeutic approach such as chemoradiation therapy. We divided our patients into two groups according to lymphadenectomy type: group A for limited (<25 resected lymph nodes) and group B for extended (>25 resected lymph nodes) lymph nodes resection. A total of 418 patients were analysed: tumour stage at diagnosis was pT2-3 pN1-3 M0 in 339 patients and pT3 N0 M0 in 79 patients. Median age at diagnosis was 68 years (range 30-92 years). A total of 306 patients (73.2%) were in group A and 112 (26.8%) in group B. The median survival time (OS) for patients in groups A and B was 58.8 and 84.8 months, respectively (P=0.0371); median DFS was 28.8 months in group A and 59.9 months in group B (P=0.0027). At multivariate analysis, extension within the gastric wall, nodal involvement and the number of resected lymph nodes appeared to affect both OS and DFS. An inadequate lymph nodes resection can affect survival and result in a higher incidence of local relapse, making the latter group of patients optimal candidates for adjuvant chemoradiation.

RESUMEN

Reconstruction of the orbit can at times be difficult when tumors of this region are resected. We describe a new surgical procedure to reconstruct the outer canthus of the orbital region, including lateral portions of the upper and lower lids. The techniques that were used until now are often limited in repairing this anatomical area, and the results we obtained with this case encourage us to utilize the superficial temporal fascia.

RESUMEN

Although octreotide has been shown to inhibit the growth of gastrointestinal (GI) tumors in vitro and in vivo, preliminary clinical trials have reported disappointing results for this somatostatin analog in patients with GI cancers. The results of these trials probably reflect the difficulty in assessing the therapeutic potential of an agent such as octreotide in GI cancers. Thus, it is possible that treatment with octreotide could be useful in the stabilization of disease if it is associated with an improvement in survival. On the basis of these considerations five randomized trials were carried out to evaluate the therapeutic potential in patients with GI cancers. Four trials (one in patients with colorectal carcinoma and three in patients with carcinoma of the pancreas) did not show any advantage of octreotide in untreated patients; in contrast, one trial reported that octreotide prolonged survival in patients with GI cancers refractory to chemotherapy. Some clinical features of the latter study (treatment with chemotherapy, different schedules) may explain these conflicting results. Although data from randomized trials suggest that octreotide is not effective in untreated asymptomatic advanced GI cancer patients, further studies are warranted to assess the efficacy of octreotide in chemotherapy refractory patients in order to clarify the impact of octreotide in terms of not only survival but also on the patients' quality of life.

RESUMEN

INTRODUCTION: Adjuvant therapy in osteosarcoma (OS) and Ewing's sarcoma (ES) is primarily directed towards treatment of subclinical lung disease. Before the advent of modern intensive chemotherapy, lung irradiation was the only available adjuvant treatment. It has proven biological activity and low morbidity. There is, however, a wide variation in its application between centres. This systematic review aims to define the evidence to support the use of lung irradiation in these diseases. DESIGN: A review of trials published between 1966 and 2000 was undertaken to determine the evidence for the use of pulmonary irradiation in OS and ES. RESULTS: Several small series of prophylactic lung irradiation (PLI) have been reported, most from over 20 years ago. These studies support the theoretical basis for the use of PLI in both OS and ES. Few randomised studies have been performed which include PLI. In OS, studies demonstrated a trend in favour of PLI compared with no adjuvant treatment and, subsequently, a level of benefit similar to that achieved with chemotherapy, but no additive effect. No studies have used PLI in addition to current standard chemotherapy regimens, or evaluated its use after successful metastatectomy. In ES, only one randomised study has addressed the role of PLI, in a comparison with vincristine, actinomycin D and cyclophosphamide combination chemotherapy with or without doxorubicin. Prolonged follow-up favoured four-drug chemotherapy. Retrospective reports from large cooperative groups suggest that the addition of whole-lung radiotherapy (WLRT) improves outcome in ES patients presenting with pulmonary metastases. However, there are no randomised study data to support this. CONCLUSIONS: Further randomised studies are necessary to clarify the role of PLI in addition to current standard chemotherapy regimens, or its use after successful metastasectomy in patients with OS. In patients with localised ES adjuvant chemotherapy appears to be superior to PLI alone, while there is little evidence to support treatment with WLRT in patients who present with pulmonary metastases.
