Weekly paclitaxel after first-line failure in patients with advanced non-small-cell lung cancer: everyday clinical practice in a single centre.

To assess the activity of weekly paclitaxel (wPCT) in pretreated patients with advanced non-small-cell lung cancer (aNSCLC). In 2005, we included wPCT 80 mg/m for 6 consecutive weeks, followed by a 2-week interval in our department's everyday clinical practice guidelines for the second-line (or subsequent) treatment of patients with nonsquamous histologies who have previously received pemetrexed-based treatments and patients with squamous histology. In the absence of clinical evidence of disease progression, patients repeat the pretreatment staging procedures after 16 weeks (two cycles) and, in the absence of disease progression or severe toxicity, continue treatment for a maximum of four courses. Between May 2005 and December 2013, we treated 60 patients (47 in second-line and 13 in third/fourth line), who received a median of two courses (range: 1-4). The most frequent toxicity was grade 1-2 neutropaenia (five patients); only four patients experienced grade 3-4 toxicity. When used as a second-line treatment, wPCT led to a disease control rate of 36.2%, with a median progression-free survival of 3.7 months and a median overall survival of 9.0 months; when used in the third/fourth line, the disease control rate was 41.7%, the median progression-free survival was 5.0 months and the median overall survival was 10.3 months. Our data confirm that wPCT is active and well tolerated in an unselected patient population with aNSCLC and can be considered a valuable alternative to docetaxel in a second-line treatment.

Prognostic factors in patients receiving third line targeted therapy for metastatic renal cell carcinoma.

PURPOSE: Several prognostic models have been proposed for metastatic renal cell carcinoma but none has been validated in patients who receive third line targeted agents. We evaluated prognostic factors in patients with metastatic renal cell carcinoma who received a third line targeted agent. MATERIALS AND METHODS: We retrospectively reviewed data on 2,065 patients with clear cell metastatic renal cell carcinoma who were treated with targeted therapy at a total of 23 centers in Italy. Included in final analysis were 281 patients treated with 3 targeted agents. Overall survival was the main outcome. Cox proportional hazards regression followed by bootstrap validation was used to identify independent prognostic factors. RESULTS: Three clinical characteristics (ECOG performance status greater than 1, metastasis at diagnosis and liver metastasis) and 2 biochemical factors (hemoglobin less than the lower limit of normal and neutrophil count greater than the upper limit of normal, respectively) were prognostic. Patients were classified into 3 risk categories, including low-zero or 1, intermediate-2 and high risk-more than 2 risk factors. Median overall survival was 19.7, 10.1 and 5.5 months, and 1-year overall survival was 71%, 43% and 15%, respectively. The major limitation was the retrospective nature of this study and absent external validation. CONCLUSIONS: This nomogram included clinical and biochemical prognostic factors. In clinical trials it may be useful to select patients and define the prognosis.

Clinical outcomes in patients receiving three lines of targeted therapy for metastatic renal cell carcinoma: results from a large patient cohort.

AIM: A number of targeted therapies (TTs) are effective in metastatic renal cell carcinoma (mRCC) but clinical outcomes with the sequential use of three TTs have been poorly investigated, this study evaluates their outcome. METHODS: Patients with clear cells mRCC treated with three TTs were retrospectively studied. Therapies were classified as vascular endothelial growth factor (VEGF)/vascular endothelial growth factor receptor (VEGFR) or mammalian target of rapamycin inhibitors (mTORi). Progression free survival (PFS), overall survival (OS) and total PFS (tPFS)--defined as the time from start of first-line to progression on third-line treatment--were estimated using the Kaplan-Meier method and curves were compared with log-rank test. RESULTS: A total of 2065 patients with mRCC were consecutively treated with first-line TT in 23 centres in Italy. Overall 281/2065 patients (13%) were treated with three TTs. Median OS and tPFS were 44.7 and 34.1 months, respectively and were longer in patients receiving the sequence vascular endothelial growth factor inhibitors (VEGFi)-VEGFi-mTORi compared with those receiving VEGFi-mTORi-VEGFi with a statistical difference in OS (50.7 versus 37.8 months, p = 0.004; 36.5 versus 29.3 months, p = 0.059, respectively). CONCLUSIONS: Few patients received three lines of TTs. The sequence VEGFi-VEGFi-mTORi was associated with improved survival with respect to VEGFi-mTORi-VEGFi and primary resistance to first-line was a negative predictive and prognostic factor.

Multiple rechallenges for castration-resistant prostate cancer patients responding to first-line docetaxel: assessment of clinical outcomes and predictive factors.

OBJECTIVE: To describe the feasibility and efficacy of multiple sequential rechallenges and analyze the predictive factors that may aid in selecting patients who are more likely to respond. Several studies have demonstrated the feasibility and activity of a single docetaxel rechallenge in patients with castration-resistant prostate cancer (CRPC), thus providing an additional opportunity for treatment in docetaxel-sensitive CRPC patients in clinical practice. MATERIALS AND METHODS: CRPC patients who completed first-line docetaxel therapy without disease progression have been offered a docetaxel rechallenge, and the responders have undergone further rechallenges until the appearance of docetaxel resistance. We assessed their clinical outcomes and evaluated all the variables potentially capable of predicting the response to rechallenge by means of uni- and multivariate analysis. RESULTS: Forty-six consecutive patients underwent 92 rechallenges. The overall biochemical response rate (prostate-specific antigen [PSA] reduction >50%) was 66%. Median overall survival was 32 months with a projected 2-year overall survival from the first docetaxel administration of 77.5%. Multivariate analysis showed that the time slope-log PSA, the time from the previous cycle, and the response to the previous cycle were predictive of the response to a rechallenge. CONCLUSION: A docetaxel rechallenge may be safely repeated several times in CRPC patients and in selected patients could improve disease control. The predictive factors found in our analysis may help select the most appropriate strategy in the light of the availability of active second-line drugs.

Estramustine plus docetaxel as second-line therapy in patients with hormone-refractory prostate cancer resistant to docetaxel alone.

OBJECTIVE: Although docetaxel (DOC) plus prednisone is currently the treatment of choice for hormone-refractory prostate cancer (HRPC), no standard therapy is available for those patients who progress during DOC treatment. The aim of this study was to evaluate whether the addition of estramustine (E) can overcome DOC resistance. METHODS: Patients who had not responded to DOC in a previous randomised phase II trial received a one-hour intravenous infusion of DOC 70 mg/m(2) on day 2 in combination with oral E 840 mg/day divided into three daily administrations on days 1-5. The primary endpoint was a >50% decrease in PSA; the secondary endpoints were biochemical progression-free survival, overall survival, the objective response rate, and toxicity. RESULTS: A biochemical response was observed in 52% of the 25 patients evaluable for response. The only grade 4 event was a cerebral stroke that occurred a few days after the administration of the first treatment course. Treatment discontinuation due to worsened compliance was observed in the patients who received a higher cumulative number of courses. CONCLUSIONS: Our findings suggest that the addition of E may be useful in selected HRPC patients resistant to DOC alone.

Docetaxel, with or without estramustine phosphate, as first-line chemotherapy for hormone-refractory prostate cancer: results of a multicentre, randomized phase II trial.

OBJECTIVE: To report the results of a randomized phase II trial of docetaxel with and without estramustine phosphate (EP) in patients with hormone-refractory prostate cancer (HRPC). PATIENTS AND METHODS: Patients with progressive HRPC were randomized to receive docetaxel 70 mg/m(2) on day 1 (arm A), or docetaxel 70 mg/m(2) on day 2 plus oral EP three times daily, at a total daily dose of 840 mg, on days 1-5 (arm B). The primary objective of the trial was to evaluate the activity of the treatments in terms of the response in prostate-specific antigen (PSA) level. RESULTS: Forty-five of the 49 patients centrally randomized to arm A and 44 of the 46 in arm B were evaluable for activity. The PSA level decreased by > or =50% in 40% of the patients in arm A and in 75% of those in arm B. The median time to PSA progression was 20 weeks in arm A and 30 weeks in arm B. The patients in arm B had an improvement in pain over time. CONCLUSION: These data support the existence of a possible advantage in combining docetaxel and EP, which should be verified in a specific randomized phase III study.

Weekly gemcitabine, paclitaxel, oxaliplatin combination chemotherapy in patients with Cisplatin-refractory germ cell tumor: preliminary experience.

Although the overall cure rate for advanced germ cell tumor (GCT) is high, the prognosis for patients with cisplatin-refractory GCT remains poor. Gemcitabine, paclitaxel, and oxaliplatin have shown significant activity as single agents in these patients. We investigated the activity and tolerance of a weekly gemcitabine, paclitaxel, oxaliplatin chemotherapy regimen. From September 2000 to February 2002, 9 patients with cisplatin-refractory GCT were treated with gemcitabine 800 mg/m2, paclitaxel 70 mg/m2, and oxaliplatin 50 mg/m2, days 1, 8, and 15, every 4 weeks. Only 1 patient stayed on schedule. In 7 patients, chemotherapy treatment was modified due to grade 3-4 hematological toxicity, whereas in another patient, who received high-dose chemotherapy 2 months before, chemotherapy was administered biweekly. In total, 21 cycles were administered with a median of 2 cycles for each patient. One patient achieved a partial remission lasting 5 months, 1 had disease stabilization for 5 months, whereas 7 had progressive disease. This chemotherapy regimen was not feasible in our patient population. Recently, oxaliplatin at full doses, but not as weekly administration, has appeared to possess activity in cisplatin-refractory GCT. Thus, we plan a phase II study protocol of the oxaliplatin and gemcitabine combination at full doses every 3 weeks.

Second-line chemotherapy with irinotecan plus carmustine in glioblastoma recurrent or progressive after first-line temozolomide chemotherapy: a phase II study of the Gruppo Italiano Cooperativo di Neuro-Oncologia (GICNO).

PURPOSE: Glioblastoma multiforme (GBM), the most frequent brain tumor in adults, is not considered chemosensitive. Nevertheless, there is widespread use of first-line chemotherapy, often with temozolomide, as a therapeutic option in patients with progressive disease after surgery and radiotherapy. However, at the time of second recurrence and/or progression, active and noncross-resistant chemotherapy regimens are required. The aim of the present multicenter phase II trial, therefore, was to ascertain the efficacy of second-line carmustine (BCNU) and irinotecan chemotherapy. PATIENTS AND METHODS: Patients with histologically confirmed GBM, recurring or progressing after surgery, standard radiotherapy and a first-line temozolomide-based chemotherapy, were considered eligible. The primary end-point was progression-free survival at 6 months (PFS-6), and secondary end-points included response rate, toxicity, and survival. All patients were on enzyme-inducing antiepileptic prophylaxis. Chemotherapy consisted of BCNU (100 mg/m2 on day 1) plus irinotecan (175 mg/m2/weekly for 4 weeks), every 6 weeks, for a maximum of eight cycles. In the absence of grade 2 toxicity, the irinotecan dose was increased to 200 mg/m2. RESULTS: A total of 42 patients (median age, 53.4 years; median Karnofsky performance status, 80; range, 60 to 90) were included in the study. PFS-6 was 30.3% (95% CI, 18.5% to 49.7%). Median time to progression was 17 weeks (95% CI, 11.9 to 23.9). Nine partial responses (21.4%; 95% CI, 9% to 34%) were obtained. Toxicity was manageable. CONCLUSION: The BCNU plus irinotecan regimen seems active and non-cross-resistant in patients with GBM with recurrence after temozolomide-based chemotherapy.

A phase II study of liposomal doxorubicin in recurrent epithelial ovarian carcinoma.

BACKGROUND: We conducted a phase II trial to evaluate the efficacy and safety of liposomal formulation of doxorubicin in recurrent ovarian carcinoma patients. METHODS: Thirty patients were included in the study after having obtained an informed consent. Their main characteristics were: median age, 64 years (range, 45-80), ECOG performance status 0 in 17 patients (56%), 1 in 11 patients (36%) and 2 in 2 patients (6.6%). Eighteen patients had metastatic disease and 12 locally advanced disease. All patients were pretreated with a platinum-based chemotherapy: 3 were considered refractory to platinum (progression or stable disease), 2 were platinum resistant (relapse < 12 months), and 7 were platinum sensitive (relapse > or = 12 months). Treatment consisted of liposomal doxorubicin, 50 mg/m2 every 4 weeks. RESULTS: The overall response rate was 26.6%, with 2 complete responses and 6 partial responses lasting 3.5 months. The incidence of grade 3-4 toxicity was 23.3% for neutropenia, 10% for mucositis and 10% for plantar-palmar erythrodysesthesia. Median survival was 12+ months (range, 2-26+). CONCLUSIONS: Liposomal doxorubicin appears to be a moderately active drug in pretreated patients, and its activity seems to be similar to that reported for other active regimens in terms of response rate. The toxicological profile of liposomal doxorubicin suggests that it may be combined with other drugs in the treatment of patients with ovarian cancer.

Phase I study of gemcitabine and radiotherapy plus cisplatin after transurethral resection as conservative treatment for infiltrating bladder cancer.

PURPOSE: Although the use of radical transurethral resection followed by concurrent radiochemotherapy leads to a similar survival rate to that achieved after cystectomy, the number of long-term survivors is low in both cases. An improvement may be obtained by adding a new drug, such as gemcitabine, which is active in bladder cancer and acts as a radiosensitizer. However, because gemcitabine may be very toxic when associated with radiotherapy, we designed this dose-finding study in an attempt to find the dose that can be safely added to radiotherapy and concurrent cisplatin in patients treated with transurethral resection for infiltrating bladder cancer. PATIENTS AND METHODS: After undergoing macroscopically complete transurethral resections for transitional carcinoma of the bladder, patients staged pT2 or higher and without distant metastases concurrently received 54 Gy of fractionated radiotherapy over 6 weeks with cisplatin (100 mg/m(2) q.3 w), starting on Day 1 of radiotherapy. Concomitant gemcitabine was administered on Days 1, 8, and 15 q.3 w for 2 cycles at a dose of 200 mg/m(2), escalated to 500 mg/m(2), with a 100 mg/m(2) increase at each dose level. The maximum tolerated dose was defined as the dose of gemcitabine associated with dose-limiting toxic effects (febrile neutropenia, Grade 4 thrombocytopenia, Grade 3 or 4 enteric toxicity, or Grade 4 nonhematologic toxicity) in 33% of the patients treated at that dose level. Six to 8 weeks after completing the therapy, the patients underwent cystoscopic reevaluation with multiple biopsies of the initial tumor site. RESULTS: Of our consecutive series of 16 patients, 5 received a gemcitabine dose of 200 mg/m(2)/week, 3 a dose of 300 mg/m(2)/week, 3 a dose of 400 mg/m(2)/week, and 5 a dose of 500 mg/m(2)/week for 6 weeks. No dose-limiting toxicity was observed at doses of up to 400 mg/m(2)/week. At the dose 500 mg/m(2)/week, 1 patient experienced an intestinal perforation that recovered after surgery, and another suddenly died after developing Grade 3 untreated diarrhea in the last treatment week. All of the 15 evaluable patients were microscopically disease free at the cystoscopic reevaluation; furthermore, the posttreatment computed tomography scans did not reveal any distant metastases. CONCLUSIONS: After transurethral resection for the conservative treatment of infiltrating bladder cancer, gemcitabine doses of up to 400 mg/m(2)/week seem to be safe in combination with cisplatin and radiotherapy in organ-sparing management. On the basis of the promising results of this Phase I study, we are currently conducting a Phase II trial to verify the possible improvement in local control resulting from the addition of gemcitabine.

Pain and quality of life after surgery for breast cancer.

BACKGROUND: In breast cancer (BC) patients, conservative surgery (CS) followed by irradiation or immediate breast reconstruction (IBR) after modified radical mastectomy (MRM) has been proposed in the attempt to avoid the negative impact of MRM on feminine body image. Regardless of the type of operation, BC patients may feel pain even without recurrent disease with poor adjustment in terms of quality of life (QL). METHODS: We adopted a questionnaire comprising the short form of the McGill Pain questionnaire, and a previously validated questionnaire able to identify four subscales exploring physical well-being, physical autonomy, relational life and psychological well-being. The questionnaire was mailed in 1999 to a consecutive series of 757 (CS: 481 cases; MRM + IBR with skin expander: 93 cases; MRM: 183 cases) disease-free patients treated for BC between March 1995 and March 1998. RESULTS: The final analysis assessed the data relating to 529 patients who underwent axillary dissection. Pain was reported by 39.7% of women with higher incidence in patients who underwent CS than in those who underwent MRM +/- IBR, but this difference did not reach statistical significance (p = 0.07). The only statistically significant difference (p < 0.05) between the surgical groups was the pain appearance that occurred earlier in the CS patients and later in the MRM + IBR patients. No other differences were observed. The women with pain had significantly worse QL scores on all of the subscales than those without. CONCLUSION: Pain after surgery for BC distress almost one-third of patients, regardless of the type of treatment, and had a negative effect on patients' QL. The different surgical procedures may marginally influence the quantitative characteristics of pain.

Late events and clinical prognostic factors in stage I non small cell lung cancer.

UNLABELLED: Two hundred and forty six consecutive patients with pathological T1-2 N0 M0 non-small cell lung cancer were reviewed. Median follow-up was 79 months (range 3-144). So far, 110 patients have relapsed (45.6%). Actuarial median time to recurrence was 26 months in the 45 patients with thoracic relapses versus 12 months of the 65 metastatic (P<0.001). Disease-free survival (DFS) rates at 5 and 10-year were 62 and 49%, respectively. Fifteen percent of the patients (20) disease-free at 5 years relapsed in the following years; of them, 40% (8) underwent new surgery. Extrapulmonary malignancies other than lung cancer occurred in 27 patients (11.2%), mostly (21) after the diagnosis of lung cancer; in this subset median time to occurrence was 52 months (range 8-105) with a rate of occurrence remaining constant over the years after operation. Univariate and multivariate analysis demonstrated that large cell histology, lower performance status (PS) and presence of symptoms were unfavourable prognostic factors both for DFS and survival. IN CONCLUSION: this study found a non-negligible proportion of late events and identified some prognostic factors (PS, presence of symptoms and large cell histology) using information obtained from routine data.
