RESUMO

UNLABELLED: Haemorrhagic cystitis (HC) is a recognised complication in patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT). This study evaluates the incidence and severity of HC in patients undergoing allogeneic HSCT during hospitalisation and within the first 100 days following transplant, looking at the use of prophylaxis, management of HC, outcomes at 100 days post transplant, and to identify any correlations between development of HC and the different conditioning regimens for transplant or HC prevention methods used. RESULTS: Four hundred and fifty patients (412 adult and 38 paediatric) were enrolled in this prospective, multicentre, and observational study. HC was observed in 55 patients (12.2%) of which 8/38 were paediatric (21% of total paediatric sample) and 47/412 adults (11.4% of total adult sample). HC was observed primarily in the non-related HSCT group (45/55; 81.8%, p= 0.001) compared to sibling and myeloablative transplant protocols (48/55; 87.3%; p= 0.008) and with respect to reduced intensity conditioning regimens (7/55;12.7%). In 33 patients with HC (60%), BK virus was isolated in urine samples, a potential co-factor in the pathogenesis of HC. The median day of HC presentation was 23 days post HSCT infusion, with a mean duration of 20 days. The most frequent therapeutic treatments were placement of a bladder catheter (31/55; 56%) and continuous bladder irrigation (40/55; 73%). The range of variables in terms of conditioning regimens and so on, makes analysis difficult. CONCLUSIONS: This multi-centre national study reported similar incidence rates of HC to those in the literature. Evidence-based guidelines for prophylaxis and management are required in transplant centres. Further research is required to look at both prophylactic and therapeutic interventions, which also consider toxicity of newer conditioning regimens.

RESUMO

AIM: Neoadjuvant chemotherapy represents a promising alternative to concomitant chemo-radiation therapy in locally advanced cervical cancer patients. The aim of this study was the evaluation of pathologic response rates, toxicity and predictors of response in locally advanced cervical cancer patients treated with neoadjuvant cisplatin and paclitaxel followed by radical surgery. METHODS: Fourteen patients with stage IB2 to IIB cervical cancer received three cycles of cisplatin 75 mg/m2 and paclitaxel 175 mg/m2 intravenously every three weeks followed by radical hysterectomy and bilateral pelvic lymphadenectomy. Toxicity, pathologic response and predictors of response were evaluated. RESULTS: Chemotherapy related toxicities we-re as follows: alopecia 100%, asthenia 35.7%; nausea and vomiting 14.3%; paclitaxel hypersensitivity 7.1%, neutropenia 7.1%. Optimal, partial and no pathologic response was achieved in 21.4%, 64.3% and 14.2% of the patients, respectively. Based on lack of pathologic risk factors, 43% of the patients did not receive any adjuvant radiotherapy. Better response rates were obtained in patients with stage IIB, tumor diameter <5 cm, Hb >12 g/dL and SCC antigen <1.5 mg/dL. None of these variables reached statistical significance. CONCLUSION: Neoadjuvant chemotherapy with cisplatin and paclitaxel in locally advanced cervical cancer appeared to be well-tolerated. Even though the TIP regimen has been shown to be more effective than the TP regimen in randomized controlled prospective trial, the TP regimen remains a reasonable alternative in those patients in whom the TIP regimen is considered or shown to be too toxic.

RESUMO

OBJECTIVE: To evaluate the accuracy of magnetic resonance imaging (MRI) in staging cervical tumors after neoadjuvant chemotherapy (NACT). METHODS: 26 women, affected by locally advanced cervical cancer and triaged for surgery after NACT, were submitted to three cycles of neoadjuvant chemotherapy. All patients were submitted to MRI before and after NACT. We evaluated the MRI sensitivity and specificity in staging cervical tumors after chemotherapy, relating MRI findings after NACT with the pathological findings as the gold standard. RESULTS: In our series, MRI sensitivity was 58.8% and specificity was 66.7%. CONCLUSIONS: In our study MRI accuracy after NACT was lower than that of MRI used to stage patients with early cervical cancer scheduled for primary surgery, reported by the literature. MRI false negative cases are the major problem because of the delay in application of an effective therapy in non responders to NACT.

RESUMO

INTRODUCTION: Current therapies for recurrent ovarian cancer (OC) yield relatively modest improvements in survival. Many drugs are available but recently a renewed interest is addressed on antimetabolite drugs. Pemetrexed (PEM) is a multitargeted antifolate cytotoxic agent mainly used in lung cancer. AREAS COVERED: This review summarizes the available evidence on the use of PEM in the treatment of OC. This article consists of material obtained via Medline, PubMed and EMBASE literature searches, up to November 2011. Currently available published data on mechanism of action, pharmacokinetics, safety and efficacy of PEM in the treatment of recurrent OC are described. EXPERT OPINION: Eight trials evaluated the use of PEM in OC patients. Studies using PEM in combination with carboplatin in platinum-sensitive OC suggested that the response rate is similar to other combination therapies. However, based on the absence of randomized trials comparing this doublet with currently used combination treatments, it is difficult to draw conclusions on the efficacy of PEM regimens in these patients. In platinum-resistant OC patients, two studies suggested that PEM alone might have equivalent activity to other single-agent treatment. Further pharmacogenomic and clinical data are warranted to better define the role of PEM in the treatment of recurrent OC.

RESUMO

BACKGROUND: asparagine-glycine-arginine-human tumour necrosis factor (NGR-hTNF), an agent selectively damaging the tumour vasculature, showed a biphasic dose-response curve in preclinical models. Previous phase I trials of NGR-hTNF indicated 0.8 and 45 µg/m(2) as optimal biological and maximum-tolerated dose, respectively. PATIENTS AND METHODS: Two sequential cohorts of 12 colorectal cancer (CRC) patients who had failed standard therapies received NGR-hTNF 0.8 or 45 µg/m(2) in combination with capecitabine-oxaliplatin (XELOX). RESULTS: Median number of prior treatment lines was 3 in the low-dose and 2 in the high-dose cohort. Overall, 21 patients had been pretreated with oxaliplatin-based regimens. No grade 3-4 NGR-hTNF-related toxicities were observed. Grade 1-2 chills were reported in 43% and 40% of cycles in the low-dose and high-dose cohorts, respectively. In the low-dose cohort, one patient achieved a partial response and five had stable disease for a median of 4.6 months. In the high-dose cohort, six patients had stable disease for a median of 3.6 months. Three-month progression-free survival (PFS) rates were 50% and 33% in the low-dose and high-dose cohort, respectively. Three patients in low-dose cohort experienced PFS longer than PFS on last prior therapy. CONCLUSIONS: Both NGR-hTNF doses were safely combined with XELOX in pretreated CRC patients. Hint of activity was apparent only with low-dose NGR-hTNF.

RESUMO

BACKGROUND: The anti-epidermal growth factor receptor (EGFR) antibody cetuximab is active in heavily pretreated patients with metastatic colorectal cancer (mCRC) both in monotherapy and in combination with chemotherapy (CT). This study assesses the antitumor activity of single-agent cetuximab in CT-naive patients. PATIENTS AND METHODS: Phase II clinical trial was used. Patients were EGFR positive by immunohistochemistry and were not candidate for radical surgery, even in the case of substantial tumor shrinkage. Cetuximab was administered weekly. RESULTS: Thirty-nine patients were treated and evaluated. The most common adverse event was skin toxicity (89% any grade; 48% grade 1; 31% grade 2; 10% grade 3). One patient had a complete response and three obtained partial responses (10% overall response rate). Thirteen patients had stable disease (34%). Twenty-two patients experienced progressive disease (56%). Overall median time to progression (TTP) was 2 months, and the responders individual TTP was 12, 9, 9, and 6 months. CONCLUSIONS: Even in chemo-naive patients, cetuximab as single agent is active only in a small fraction of mCRC, similarly to what has been reported for heavily pretreated patients. The extent of benefit when response occurs is, however, such that it is mandatory to intensify the search for the predictive markers of response to cetuximab therapy.

RESUMO

With ageing, function preservation and maintenance of quality of life represent a major goal in an increasing proportion of patients. Life expectancy is a function of age, comorbidity, disability and cancer type and stage. Decision-making involves a delicate balance among all these factors, evaluation of treatment related complications of the overall effects of cancer and cancer treatment on the patients' quality of life. Despite several instruments for the assessment of quality of life being validated, none have been calibrated to the special requirements of the older patients. The structured interview administered by a trained clinician represents a standard approach for geriatric research and even for clinical practice because of the frailty of the older population. The combination of this approach with the self-administered questionnaire appears the most effective way to minimise missing data in collecting information for patients unable to complete the form.

RESUMO

From June 1990 to October 1994, 111 advanced ovarian cancer patients with minimal (less than 2 cm) residual disease after platinum-based front-line chemotherapy and second-look laparotomy entered a cooperative randomized study aimed at evaluating the effectiveness and the toxicity of the addition of interferon-alpha2 to carboplatin, both intraperitoneally (ip) administered. Patients were randomized to receive either 3 courses of ip Carboplatin 400 mg/m2 Day 1 q 28 days (54 pts) (CBDCA) or ip interferon-alpha 25 x 10(6) U Day 1 + ip carboplatin 400 mg/m2 Day 2 q 28 days (57 pts) (CBDCA + IFN). Patients treated with interferon experienced more severe (WHO grade 3-4) leukopenia (28% vs 17.1%) and anemia (14% vs 4.2%). Fever (P = 0.000) and flu-like syndrome (P = 0.02) were significantly more frequent in the combination arm. No difference in gastroenteric, neurologic, or renal toxicity was observed. At a median follow-up time of 13 months (range 1-72) 71 patients showed a disease progression (31 CBDCA, 40 CBDCA + IFN) and 44 patients died (21 CBDCA, 23 CBDCA + IFN). Median progression-free survival was 11 months in the CBDCA group and 10 months in the CBDCA + IFN arm. Median survival was 22 and 29 months in CBDCA and CBDCA + IFN arm, respectively. In conclusion, intraperitoneal interferon-alpha does not seem to improve the results achievable with intraperitoneal carboplatin in this subset of patients, while the toxicity and the costs of the combination are consistently higher than with chemotherapy alone.

RESUMO

BACKGROUND: While ovarian cancer is one of the most sensitive cancers to cytotoxic drugs, with objective response rates of 60-80% routinely being reported in previously untreated patients, the majority of individuals with advanced disease ultimately relapse. Paclitaxel, a new and novel antimicrotubule agent, has shown activity as a salvage therapy in epithelial ovarian cancer. More importantly, in a prior study, it has been shown to be active in tumors that have displayed resistance to platinum compounds, with a reported response rate of 20%. Ifosfamide has shown activity in the treatment of patients who previously demonstrated clinical resistance to a platinum-cyclophosphamide combination. Recently, a synergistic activity of Taxol combined with ifosfamide has been reported in ovarian cell lines. Based on these data, a phase I/II study of a combination treatment with paclitaxel and ifosfamide was performed. PATIENTS AND METHODS: Thirty-one patients with recurrent ovarian cancer or ovarian cancer refractory to cisplatin (CDDP)-containing regimens were treated with paclitaxel at a dose of 135 mg/m2 on day 1; ifosfamide was administered at 1 g/m2 on days 2 and 3 for the first cycle and 1.5 and 2 g/m2 with the same schedule in cycles 2 and 3, respectively. In the absence of toxicity, the dose of ifosfamide was maintained at 2 g/m2 for the last three cycles. Cytotoxic therapy was repeated every 3 weeks. RESULTS: A 30% overall objective response rate was achieved in the 30 patients assessable for response. Among 21 platinum-resistant patients, 4 partial responses (19%) were observed, while in the 9 platinum-sensitive patients 2 complete responses and 3 partial responses (55%) were observed. Myelosuppression was the predominant toxicity. Leukopenia (WHO grade 3-4) occurred in 10% of patients who received ifosfamide at a dose of 1 g/m2 and in 18% of patients treated with ifosfamide at 1.5 g/m2. CONCLUSION: Our results confirmed a low activity of paclitaxel in platinum-resistant patients. The results of this combination treatment with paclitaxel-ifosfamide in our platinum-sensitive patients support further investigations in a randomized study of the combination regimen against paclitaxel alone or retreatment with organoplatinum compounds.

RESUMO

Encouraging results with Paclitaxel are reported in ovarian cancer patients relapsing and progressing after platinum-based chemotherapy; however, the two populations have different probabilities of a response to a second-line treatment. Here we report the results achieved in 39 patients with platinum-refractory ovarian cancer, treated with Paclitaxel 175 mg/qm2 (or 135 mg/m2 if heavily pretreated) using 3-hour intravenous infusion every 3 weeks, in an attempt to verify the activity of this drug in platinum-resistant patients. The toxicity was mild to moderate and primarily hematologic and neurologic. The objective response rate is 12.8% with no complete responses. The response duration was brief and the median survival 6 (range 1-17) months. An accurate cost-benefit balance is necessary before routinely use of Paclitaxel in platinum-refractory patients. Further research is needed to determine the optimal role of Paclitaxel in the whole therapeutic strategy for ovarian cancer.

RESUMO

PURPOSE: The aim of the study was to compare high-versus low-dose cisplatin in combination with cyclophosphamide and epidoxorubicin as primary chemotherapy for suboptimal stage III and IV ovarian cancer. PATIENTS AND METHODS: One hundred forty-five patients were randomized to receive six courses of cisplatin 50 or 100 mg/m2 plus epidoxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2. The two treatment arms were well balanced; all patients had greater than 2 cm and 37.2% had greater than 5 cm of residual disease; 29.6% had stage IV disease. RESULTS: Patients in the high-dose arm received a double dose-intensity and double total dose of cisplatin. The high-dose regimen induced significantly more episodes of leukopenia (47.8% v 32.8%, P = .05), thrombocytopenia (21.7% v 3.2%, P = .003), anemia (37.6% v 12.5%, P = .002), nephrotoxicity (six v one patient), and neurotoxicity (30.4% v 6.3%, P = .002). There were no significant differences in efficacy in terms of clinical response rate (high-dose 57.5% v low-dose 61.1%), pathologic complete response (CR) (9.6% v 18.1%), median survival times (29 v 24 months), and median progression-free survival (18 v 13 months). CONCLUSION: This study shows that doubling the dose-intensity and total dose of cisplatin in combination with epidoxorubicin and cyclophosphamide has significant toxic effects and does not improve clinical outcome in patients with suboptimal ovarian cancer.

RESUMO

We have carried out a phase II trial to evaluate the efficacy and toxicity of a combination therapy consisting of mitoxantrone 10 mg/sqm i.v. on day 1, levo-leucovorin 250 mg/sqm administered over 2 hours and 5-fluorouracil 500 mg/sqm i.v. push after the first hour of levo-leucovorin infusion, on days 15-16 (MFL) in patients aged more than 65 years. 24 patients with advanced breast cancer entered the study: 16 aged 65-70 yrs, 4 patients 70-75 yrs, and 4 > 75 yrs. Median PS was 1 (range 0-2); sites of metastases were: bone 14 patients, viscera 14 patients, soft tissue 11 patients, and CNS 1 patient. A median number of 6 cycles (range 3-9) was administered. All patients were evaluable for response and toxicity; partial response was obtained in 12 (50%) patients (95% C.I 30-70), stable disease was observed in 9 patients (37.5%), while 3 patients (12.5%) progressed. Median progression-free survival and survival were 9 months (range 2-14) and 14 months (range 5-36), respectively. Toxicity was generally mild and the most frequently observed side-effects were WHO gr. 1-2 leukopenia in 6/24 (25%) patients and gr. 1-2 emesis in 10/24 (41.6%) pts. 1 patient pretreated with doxorubicin cumulative dose of 240 mg/sqm showed clinical signs of congestive heart failure (NYHA grade 1) after the fifth cycle of treatment. MFL is a well tolerated regimen and could represent a safe and effective treatment in older advanced breast cancer patients.

RESUMO

Based on experimental findings suggesting that 5-fluorouracil (FUra) may have different mechanisms of action depending on the schedule of administration, we generated the hypothesis that biochemical modulation of this fluoropyrimidine should be schedule specific. We thus tested the activity of a hybrid regimen consisting of two biweekly cycles of FUra bolus (600 mg/m2) modulated by pretreatment (24-h interval) with methotrexate (200 mg/m2), alternating with a 3-week continuous infusion of FUra (200 mg/m2/day) modulated by low-dose (6S)leucovorin (20 mg/m2 bolus weekly). Thirty-three consecutive patients with advanced measurable colorectal cancer and no prior therapy for metastatic disease entered the study from February 1992 to August 1993. They were treated with two biweekly cycles of FUra bolus (600 mg/m2) preceded by (24-h interval) methotrexate (200 mg/m2), alternating with a 3-week continuous infusion of FUra (200 mg/m2/day) modulated by low-dose (6S)leucovorin (20 mg/m2 bolus weekly). The median Eastern Cooperative Oncology Group performance status was 1; the liver was the only metastatic site in 17 patients. Treatment outcome was evaluated by computed tomographic scan in all patients, except for two. Three complete and 13 partial responses were obtained among these 33 patients (response rate, 48%; 95% confidence limits, 31-66%). Performance status (Eastern Cooperative Oncology Group) influenced clinical response. The combined complete response and partial response rate was 69%, 33%, and 25% in patients with an Eastern Cooperative Oncology Group performance status of 0, 1, and 2, respectively (chi2, 4.6, P = 0.032, two-tailed Mantel test for trend). After a median follow-up time of 26 months, 10 patients are still alive. The median progression-free survival and overall survival were 9.5 and 20.2 months, respectively. No toxic deaths or grade 4 toxicity occurred. The incidence of grade 3 toxicity per patient in any cycle was: mucositis 6%, diarrhea 3%, and vomiting 3% for the bolus part and 21%, 3%, and 6%, respectively, for the continuous infusion part of the regimen. Hand-foot syndrome occurred in 27% of the patients treated with the continuous infusion regimen.

RESUMO

We have evaluated the efficacy and toxicity of a chemotherapy consisting of methotrexate, mitoxantrone, 5-Fluorouracil and leucovorin in 21 advanced breast cancer patients. Among 20 evaluable patients, objective response was obtained in 6 patients (30%) with two complete responses, stable disease in 4 patients (20%), while 10 patients (50%) progressed. Median progression-free survival and survival were 10 and 15 months, respectively. The most frequently observed side-effects were myelosuppression and emesis; one patient, who had previously received doxorubicin at the maximum dose-limiting cardiac toxicity, died of congestive heart failure after the third cycle. This treatment is moderately effective for advanced breast cancer patients.

An incidence of cerebral metastases secondary to epithelial ovarian cancer as high as 11.6% has been reported in small series and related to the prolonged survival of ovarian cancer patients treated with platinum compounds (Hardy, J. R., and Harvey, V. J. Gynecol. Oncol. 33, 296-300, 1989). A review of the histories of 413 ovarian cancer patients, treated from 1981 to 1989 with platinum-based combination chemotherapy according to the protocols of the Gruppo Oncologico Nord Ovest (GONO) (North West Oncology Group), showed that only 9 patients (2.2%) developed clinical evidence of cerebral metastases. Six of 9 patients had FIGO Stage IIIc disease and 1 each with FIGO Stages Ic, IIc, and IV. All these patients had received cisplatin or carboplatin-based combination chemotherapy. Clinical response to initial cytotoxic therapy was as follows: complete response, 3 patients; partial response, 4 patients; stable disease, 1 patient; progressive disease, 1 patient. Cerebral metastases occurred at a median of 19 months (range 3-36) from diagnosis and median survival of patients with central nervous system (CNS) metastasis was 26 months (range 10-81) from diagnosis of primary disease and 8 months (range 1-45) from diagnosis of CNS involvement. The incidence of CNS metastases in our series is similar to that reported in the past and significantly lower than figures reported by the above mentioned paper. On the basis of our data we do not agree with Hardy and Harvey about the relationship possibly existing between prolonged survival and incidence of CNS metastases and, particularly, about the need for prophylactic cranial irradiation.

RESUMO

It has been demonstrated that the prognosis of ovarian cancer is influenced by the dose intensity of cytotoxic treatment. The impact of received dose intensity of platinum-based combination chemotherapy on disease outcome was analysed in 226 stage III-IV ovarian cancer patients entered into two prospective randomised trials. All patients received either cisplatin or carboplatin and cyclophosphamide with or without doxorubicin for six courses after primary surgery. The impact of the received dose intensity of each drug (RDI), the average received dose intensity of the treatment regimen (ARDI) and the relative total drug dose (RTD) on progression-free survival (PFS) and survival were analysed. In the 198 patients receiving the full six courses of treatment, RDI of cisplatin or carboplatin, ARDI and RTD were > 0.76 in 74.2, 61.1 and 65.1% of cases, respectively. Although the differences were not significant, pathological complete response was more frequently observed in the group of patients with ARDI < 0.75, whereas the partial response rate was higher in the ARDI > or = 0.76 group. Median survival and PFS were 19 and 13 months; 22 and 10 months; 23 and 13 months for the groups of patients receiving chemotherapy at a ARDI of < 0.75, > or = 0.76-0.99 and > 1.00, respectively (P = not significant). It appears that modest dose modifications and brief treatment delays during first-line platinum-based chemotherapy do not affect response rate, survival and PFS in advanced ovarian cancer patients.

RESUMO

In 221 patients with FIGO stage I and II endometrial carcinoma, the impact on survival of age at diagnosis, menopausal status, FIGO stage, myometrial invasion, tumor grade and histology was evaluated by univariate and multivariate analysis. At a median follow-up of 50 months (range 45-210), 42 patients had died, and therefore overall survival was 81% (179/221). Univariate analysis showed that age, menopausal status and histology did not influence survival, whereas FIGO stage, myometrial invasion and tumor grade were important prognostic factors. Multivariate analysis showed that tumor grade had a significant and independent impact on survival and confirmed that FIGO stage is the most important parameter influencing survival.

RESUMO

The efficacy of the serotonin antagonist ondansetron (GR 38032F) was evaluated in the prevention of nausea and vomiting induced by CMF chemotherapy in 29 breast cancer patients. At their first treatment course of CMF, all given IV on day 1 q 21 days, patients were given oral antiemetic treatment as follows: ondansetron 8 mg, 2 h prior to CMF, repeated after 5 and 10 h the day of chemotherapy and then 8 mg tds for a minimum of 3 days to a maximum of 5 days following chemotherapy. At first course of CMF, complete protection from emesis and nausea was observed in 86.2% and 62% of patients, respectively. At subsequent CMF courses with ondansetron, complete control of emesis was observed in 80% of patients. Side effects were mild and no dystonic reactions were observed. Ondansetron represents an effective, safe, and easily administered outpatient regimen. The addition of a corticosteroid to ondansetron could further improve control of CMF-induced emesis.

RESUMO

87 patients with high risk of recurrence FIGO stage I and II ovarian carcinoma were treated with adjuvant chemotherapy consisting of cisplatin 50 mg/m2 plus cyclophosphamide 600 mg/m2 on day 1 every 28 days for 6 courses. Toxicity and efficacy of the regimen was evaluated after a median follow-up of 45 months. Treatment-related toxicity was mild and reversible, consisting chiefly of acute WHO grade 2 myelosuppression (10% of patients) and controllable grade 3 emesis (55%). No late toxicity was observed. Actuarial 7-year survival and relapse-free survival (RFS) were 76% and 61%, respectively; a statistically significant difference in outcome was observed for undifferentiated grade tumour (G1 vs. G2 vs. G3: P less than 0.01) but not for FIGO stage disease (stage I vs. stage II). In our opinion, short-term chemotherapy including the most active single agent, i.e. cisplatin, appears a tolerable and effective treatment which deserves further evaluation in large randomised trials.
