Clinical benefit of switching from paclitaxel to docetaxel or vice versa in cutaneous angiosarcoma patients resistant to first taxane chemotherapy. J Dermatol 2023; 50:1493-1496. [PMID: 37400887 DOI: 10.1111/1346-8138.16873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 06/08/2023] [Accepted: 06/12/2023] [Indexed: 07/05/2023]
Abstract
Cutaneous angiosarcoma (CAS) is a rare soft-tissue sarcoma of vascular endothelial origin. Paclitaxel (PTX) and docetaxel (DTX) are used as systemic chemotherapy; however, chemoresistance often occurs in CAS. Switching one taxane to the other (i.e., PTX to DTX, or vice versa) is an option when the first taxane is no longer effective in malignant cancers such as ovarian or breast cancer. However, the efficacy of the same strategy in CAS has not been reported. Herein, we report the clinical response of switching one taxane-based chemotherapy to the other in CAS patients with resistance to the first taxane. Twelve CAS patients were included for analyses. In all patients, the median overall survival from the start of the first taxane treatment was 29.0 months (range, 6.47-58.5). During the first taxane, the median PFS for all patients was 5.96 months (1.81-47.1). Similarly, the median (range) PFS for all patients during the second taxane was 5.87 months (1.60-18.2). Furthermore, the median OS was 22.7 months (PTX to DTX) and 39.5 months (DTX to PTX) (p = 0.307). The median PFS during the first taxane was 5.14 (PTX to DTX) and 12.5 months (DTX to PTX), respectively (p = 0.380). The median PFS during the second taxane was 3.5 (PTX to DTX) and 7.1 months (DTX to PTX), respectively (p = 0.906). The objective response rate, defined as the sum of complete response (CR) and partial response (PR) rates, was 16.7%. The disease control rate, defined as the sum of CR, PR, and stable disease rates, was 50%. The frequency of adverse events during the second taxane was the same between the two groups (p > 0.999). Our report suggests that CAS patients could benefit from the second taxane treatment if the tumor is resistant to the first taxane.

Abstract
Peritoneal carcinomatosis (PC) is a common outcome of epithelial ovarian carcinoma and is the leading cause of death for these patients. Tumor location, extent, peculiarities of the microenvironment, and the development of drug resistance are the main challenges that need to be addressed to improve therapeutic outcome. The development of new procedures such as HIPEC (Hyperthermic Intraperitoneal Chemotherapy) and PIPAC (Pressurized Intraperitoneal Aerosol Chemotherapy) have enabled locoregional delivery of chemotherapeutics, while the increasingly efficient design and development of advanced drug delivery micro and nanosystems are helping to promote tumor targeting and penetration and to reduce the side effects associated with systemic chemotherapy administration. The possibility of combining drug-loaded carriers with delivery via HIPEC and PIPAC represents a powerful tool to improve treatment efficacy, and this possibility has recently begun to be explored. This review will discuss the latest advances in the treatment of PC derived from ovarian cancer, with a focus on the potential of PIPAC and nanoparticles in terms of their application to develop new therapeutic strategies and future prospects.

Insights into ovarian cancer: chemo-diversity, dose depended toxicities and survival responses. Med Oncol 2023; 40:111. [PMID: 36871128 DOI: 10.1007/s12032-023-01976-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 02/09/2023] [Indexed: 03/06/2023]
Abstract
Ovarian cancer has been one of the serious concerns for female health and medicinal practitioner all over the world. The wellness of over cancer patient is associated with survival responses which depends on many factors including chemotherapeutic diversity; treatment protocol; dose-dependent toxicity such as hematological toxicity and non-hematological toxicity. We found that the studied treatment regimens (TRs) (1-9) showed varying degree of hematological toxicities like moderate neutropenia (< 20%) critical neutropenia (> 20%), negligible leucopenia, critical leucopenia (> 20%), moderate thrombocytopenia (< 20%), critical thrombocytopenia (> 20%), moderate anemia (< 20%) and critical anemia (> 20%). The studied TRs showed varying degree of non-hematological toxicities like moderate nausea-vomiting (< 20%), critical nausea-vomiting (> 20%), moderate alopecia (< 20%), critical alopecia (> 20%), moderate fatigue (< 20%), critical fatigue (> 20%), moderate neurotoxicity (< 20%), critical neurotoxicity (> 20%), moderate diarrheas (< 20%). The studied TRs showed varying degree of survival responses like critical partial response (> 35%), remarkable overall responses (> 60%), critical overall responses (< 60%), remarkable stable disease (> 20%), critical stable disease (< 20%) and moderate progressive disease (< 20%). Out of the studied TRs 1-9, in case of TR 6, moderate non-hematological toxicity (NHT) and effective survival response (SR) is being diluted by critical hematological toxicity (HT). On the other hand, TR 8, 9 is showing critical HT, NHT and SR. Our analysis revealed that the toxicity of the existing therapeutic agents can be controlled through judicious decision of drug administration cycles and combination therapies.

Randomised phase II trial of weekly ixabepilone ± biweekly bevacizumab for platinum-resistant or refractory ovarian/fallopian tube/primary peritoneal cancer. Br J Cancer 2022; 126:1695-1703. [PMID: 35149854 PMCID: PMC8853032 DOI: 10.1038/s41416-022-01717-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 12/26/2021] [Accepted: 01/25/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND This multi-center RP2 study assessed activity/safety of ixabepilone + bevacizumab compared to ixabepilone in platinum-resistant/refractory ovarian/fallopian tube/primary peritoneal cancer. Additional objectives were to examine the role of prior bevacizumab and taxanes, and explore class III-ß-tubulin (TUBB3) as a predictive biomarker. METHODS Participants were randomised to receive ixabepilone 20 mg/m2 days 1, 8, 15 with (IXA + BEV) or without (IXA) bevacizumab 10 mg/kg days 1, 15 every 28 days. Patients were stratified by prior BEV. The primary endpoint was PFS. OS, safety, and ORR served as secondary endpoints. RESULTS Among 76 evaluable patients who received IXA + BEV (n = 39) compared to IXA (n = 37), the ORR was 33% (n = 13) versus 8% (n = 3)(P = 0.004), durable at 6 months in 37% (n = 14) and 3% (n = 1) (P < 0.001). BEV significantly improved PFS (median:5.5 vs 2.2 months, HR = 0.33, 95%CI 0.19-0.55, P < 0.001) and OS (median:10.0 vs 6.0 months, HR = 0.52, 95%CI 0.31-0.87, P = 0.006). Both regimens were well-tolerated. TUBB3 expression did not predict response. Subgroup analyses revealed minimal effect of prior BEV or taxane resistant/refractory status on response to IXA + BEV. CONCLUSIONS IXA + BEV is a well-tolerated, effective combination for platinum/taxane-resistant ovarian cancer that extends PFS and likely OS relative to IXA monotherapy. Prior receipt of BEV should not preclude the use of IXA + BEV. TUBB3 is not a predictive biomarker. CLINICAL TRIAL REGISTRATION NCT3093155.

Abstract
Simple Summary Fatigue in older patients has multiple etiologies, as this symptom may be cancer-related, treatment-related, age-related, or part of frailty syndrome. Physicians need to identify this symptom and understand its risk factors but also evaluate the risk/benefit ratio of cancer treatments considering the risk of impairing the patient’s quality of life. This scoping review was aimed to present the level of information currently available on any-grade fatigue and grade 3 or more fatigue for each cancer treatment regimen, either in general or in older populations, for the most prevalent tumors. Abstract Fatigue is a highly prevalent symptom in both cancer patients and the older population, and it contributes to quality-of-life impairment. Cancer treatment-related fatigue should thus be included in the risk/benefit assessment when introducing any treatment, but tools are lacking to a priori estimate such risk. This scoping review was designed to report the current evidence regarding the frequency of fatigue for the different treatment regimens proposed for the main cancer indications, with a specific focus on age-specific data, for the following tumors: breast, ovary, prostate, urothelium, colon, lung and lymphoma. Fatigue was most frequently reported using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) versions 3 to 5. A total of 324 regimens were analyzed; data on fatigue were available for 217 (67%) of them, and data specific to older patients were available for 35 (11%) of them; recent pivotal trials have generally reported more fatigue grades than older studies, illustrating increasing concern over time. This scoping review presents an easy-to-understand summary that is expected to provide helpful information for shared decisions with patients regarding the anticipation and prevention of fatigue during each cancer treatment.

Abstract
Infections represent a significant cause of morbidity and mortality in cancer patients. Multiple factors related to the patient, tumor, and cancer therapy can affect the risk of infection in patients with solid tumors. A thorough understanding of such factors can aid in the identification of patients with substantial risk of infection, allowing medical practitioners to tailor therapy and apply prophylactic measures to avoid serious complications. The use of novel treatment modalities, including targeted therapy and immunotherapy, brings diagnostic and therapeutic challenges into the management of infections in cancer patients. A growing body of evidence suggests that antibiotic therapy can modulate both toxicity and antitumor response induced by chemotherapy, radiotherapy, and especially immunotherapy. This article provides a comprehensive review of potential risk factors for infections and therapeutic approaches for the most prevalent infections in patients with solid tumors, and discusses the potential effect of antibiotic therapy on toxicity and efficacy of cancer therapy.

Abstract
Despite extensive research, resistance to chemotherapy still poses a major obstacle in clinical oncology. An exciting strategy to circumvent chemoresistance involves the identification and subsequent disruption of cellular processes that are aberrantly altered in oncogenic states. Upon chemotherapeutic challenges, lysosomes are deemed to be essential mediators that enable cellular adaptation to stress conditions. Therefore, lysosomes potentially hold the key to disarming the fundamental mechanisms of chemoresistance. This review explores modes of action of classical chemotherapeutic agents, adaptive response of the lysosomes to cell stress, and presents physiological and pharmacological insights pertaining to drug compartmentalization, sequestration, and extracellular clearance through the lens of lysosomes.

Abstract
AbstractDrug development in oncology has witnessed a revolutionary growth from its humble beginning with nitrogen mustard in 1940 to immunotherapy in 1986 (Interferon alpha). The arsenal of cytotoxics is ever increasing, contributing to better survival outcomes and improved quality of life. Over the years, many cytotoxics have fallen out of favor too, due to its side effects and availability of drugs with better efficacy and toxicity profile. Taxane, a microtubule stabilizing agent extracted from the poisonous Yew tree, was discovered in 1964 and came into clinical use in 1992 with its approval for ovarian cancer. This group has grown into a cornerstone of many treatment protocols, spanning multiple tumor types. This review discusses in brief the salient features of cytotoxic agents in this drug group, its history, physico-chemical properties, mechanism of action, pharmacodynamics, and pharmacokinetics. Though the benefits of taxanes are well understood, there are unique problems associated with the use of taxanes and there is an expanding literature on taxane resistance. We briefly look at the resistance mechanisms. There have been significant efforts to circumvent the problems related to conventional taxanes, with an attempt at creating newer carrier molecules and adjunct drugs with taxanes, which is slowly gaining traction in clinical practice.

Abstract
Enzymes of the cytochrome P450 (CYP) subfamily 3A and 2C play a major role in the metabolism of taxane anticancer agents. While their function in hepatic metabolism of taxanes is well established, expression of these enzymes in solid tumors may play a role in the in situ metabolism of drugs as well, potentially affecting the intrinsic taxane susceptibility of these tumors. This article reviews the available literature on intratumoral expression of docetaxel- and paclitaxel-metabolizing enzymes in mammary, prostate, lung, endometrial, and ovarian tumors. Furthermore, the clinical implications of the intratumoral expression of these enzymes are reviewed and the potential of concomitant treatment with protease inhibitors (PIs) as a method to inhibit CYP3A4-mediated metabolism is discussed.

Abstract
INTRODUCTION Docetaxel (DTX) is one of the most important chemotherapeutic agents and has been widely used for treatment of various types of cancers. However, the clinical chemotherapy of DTX gives many undesirable side effects due to the usage of organic solvent in the injection and its low selectivity for tumor cells. With the evolution of pharmaceutical technologies, great efforts have been paid to develop new DTX formulations to overcome these problems. AREAS COVERED This review provided an overview of the preparation and activities of new DTX formulations, which were classified by administration methods, including injection, oral, transdermal and rectal administration. Besides, up to date information of the clinical status of new DTX formulations was summarized. We also discussed the challenges and perspectives of the future development of DTX formulations. EXPERT OPINION There have been numerous studies on new DTX-based formulations in recent years, and many of them exhibited significantly enhanced anti-tumor and targeting activity compared with DTX in preclinical studies. However, only a few entered clinical trials, and none has been approved into market. The clinical translation of experimental drug faces many hurdles, including the limited knowledge of nanomedicine and oncology, safety issues, controllable and reproducible production.

Chen P, Jiao L, Wang DB. Squamous cell carcinoma antigen expression in tumor cells is associated with the chemosensitivity and survival of patients with cervical cancer receiving docetaxel-carboplatin-based neoadjuvant chemotherapy. Oncol Lett 2017; 13:1235-1241.

Abstract
The present study examined the association between squamous cell carcinoma antigen (SCCA) expression and the response of patients with cervical cancer to docetaxel-carboplatin (DC) combination chemotherapy, in order to determine the prognostic potential of SCCA expression. A total of 21 patients were enrolled with stage IB2 or stage IIA2 SCC. Of these, 9 patients had chemotherapy-sensitive cancer (2 cases with a complete response and 7 cases with a partial response) and 12 patients had chemotherapy-resistant cancer (12 cases of stable disease and no cases of progressive disease). Patients were treated with two cycles of DC chemotherapy (docetaxel 75 mg/m2 plus cisplatin 25 mg/m2) with 21-day intervals, followed by radical surgery. SCCA expression levels prior to and following chemotherapy were evaluated using immunohistochemistry. Following DC chemotherapy, the SCCA expression levels decreased in the patients with chemotherapy-sensitive cancer, but not in those with chemotherapy-resistant cancer (P=0.042). Significant survival differences between the SCCA-positive and -negative patients following chemotherapy (P=0.009) was observed. However, no statistically significant difference in survival between patients with chemotherapy-sensitive and chemotherapy-resistant cancer, or between patients with SCCA-positive and -negative expression prior to chemotherapy was observed. Overall, the chemotherapy sensitivity of patients with cervical cancer was associated with decreased SCCA expression levels following DC chemotherapy. Therefore, SCCA expression levels following DC chemotherapy may potentially be used in the clinical prognosis for cervical cancer patients who receive DC chemotherapy and subsequent radical surgery.

Abstract
OBJECTIVE Most patients with epithelial ovarian cancer will experience a recurrence; currently, there is no cure. In patients with platinum-sensitive disease (platinum-free interval >6 months), a combination similar to that used as frontline therapy (carboplatin and paclitaxel) is recommended. However, it is associated with a high incidence (20%) of neurotoxicity. This study evaluated the efficacy and toxicity of combination docetaxel/carboplatin therapy in patients with platinum-sensitive recurrent ovarian cancer. METHODS Forty patients with recurrent, histologically proven ovarian, fallopian tube, or primary peritoneal cancer were enrolled in this phase 2 trial. The study protocol included combination therapy with docetaxel, 30 mg/m, on days 1 and 8, and carboplatin, area under the curve 5, on day 1, every 21 days. Twenty received the classical paclitaxel/carboplatin regimen (control group), and another 20 received the modified docetaxel/carboplatin protocol (study group). RESULTS Median follow-up was 78 months for the study group and 62 months for the control group. The study group had a higher overall response rate compared to controls: 80% and 30%, respectively (P = 0.004; relative risk, 9.3; 95% confidence interval, 2.18-39.96). Complete response was achieved in 60% and 25%, respectively (P = 0.054). The study group patients showed a superior 2-year survival rate of 75% compared with the 35% of the controls (P = 0.011; relative risk, 5.57; 95% confidence interval, 1.47-21.56). Hematological and neurological toxicity rates did not differ between the groups (P = 0.451 and P = 0.605, respectively). CONCLUSIONS Patients with recurrent ovarian cancer who received the modified docetaxel/carboplatin regimen had higher overall response and survival rates compared to those who had the paclitaxel/carboplatin regimen, with no difference in toxicity. Future larger studies should focus on strategies to compare this regimen to the current standard, with an emphasis on quality of life.

Abstract
PURPOSE Breast cancer is a heterogeneous disease, characterized by various molecular phenotypes that correlate with different prognosis and response to treatments. Taxanes are some of the most active chemotherapeutic agents for breast cancer; however, their utilization is limited, due to hematologic and cumulative neurotoxicity on treated patients. To understand why only some patients experience severe adverse effects and why patients respond and develop resistance with different rates to taxane therapy, the metabolic pathways of these drugs should be completely unraveled. The variant forms of several genes, related to taxane pharmacokinetics, can be indicative markers of clinical parameters, such as toxicity or outcome. METHODS The search of the data has been conducted through PubMed database, presenting clinical data, clinical trials and basic research restricted to English language until June 2015. RESULTS We studied the literature in order to find any possible association between the major pharmacogenomic variants and specific taxane-related toxicity and patient outcome. We found that the data of these studies are sometimes discordant, due to both the small number of enrolled patients and the heterogeneity of the examined population. CONCLUSIONS Among all analyzed genes, only CYP1B1 and ABCB1 resulted the strongest candidates to become biomarkers of clinical response to taxane therapy in breast cancer, although their utilization still remains an experimental procedure. In the future, greater studies on genetic polymorphisms should be performed in order to identify differentiating signatures for patients with higher toxicity and with resistant or responsive outcome, before the administration of taxanes.

Abstract
The use of taxanes in the treatment of gynecologic malignancies has expanded tremendously over the past 30 years. Both paclitaxel and docetaxel have unique microtubule stabilizing, antiangiogenic and radiation sensitizing properties that endow them with remarkable activity as chemotherapeutic agents. As research into the appropriate dose, timing, treatment interval, and response rates have been studied, they have emerged as one of the most active agents available in the treatment of gynecologic cancer. The body of research on taxanes continues to expand especially with regard to the use of taxanes in alternative formulations and in combination with newer treatments or routes of treatment. This review focuses on the development of taxanes as an effective therapy in the treatment of gynecologic cancers and data currently available in the literature regarding their efficacy. Future directions of taxane-based chemotherapy with regards to ovarian, uterine, and cervical cancers are also addressed. There is little doubt that taxane-based chemotherapy will remain an integral part of the treatment of gynecologic cancer for the foreseeable future.

Abstract
Ovarian and endometrial cancers diagnosed at advanced stages are often associated with malignant ascites. This study aimed to determine the safety, feasibility and efficacy of intraperitoneal (IP) docetaxel (TXT) for the treatment of ascites. A phase I study, including nine patients, was undertaken to determine the maximum tolerable dose. Efficacy was retrospectively assessed in 18 patients treated with 40-70 mg/m(2) IP TXT between 2005 and 2012. In a phase I study, the dose was safely escalated to a maximum of 70 mg/m(2), at which level no patients had grade -3 haematological adverse events. In a retrospective study of 18 patients, seven had an Eastern Cooperative Oncology Group performance status of 3; 16 had prior paclitaxel administration and two, with doses of 40 and 70 mg/m(2), experienced a serological response and a decrease in paracentesis. Thus, palliative treatment of recurrent OC should be further studied with 40 mg/m(2) among more patients, and 70 mg/m(2) could be evaluated for first-line IP chemotherapy.

Abstract
This review is aimed at combining the published data on taxane formulations into a generalized Drug Delivery approach, starting from the physicochemistry and assessing its relationships with the pharmacokinetics, the biodistribution and the pharmacodynamics. Owing to the number and variety of taxane formulation designs, we considered this class of cytotoxic anticancer agents of particular interest to illustrate the concepts attached to this approach. According to the history of taxane development, we propose a classification as (i) "surfactant-based formulations" first generation, (ii) "surfactant-free formulations" second generation and (iii) "modulated pharmacokinetics drug delivery systems" third generation. Since our objective was to make the link between (i) the physicochemistry of the drug and carrier and (ii) the efficacy and safety of the drug in preclinical animal models and (iii) in human, we focused on the drug delivery technologies that were tested in clinic.

Abstract
OBJECTIVE Evaluate the cost-effectiveness of primary prophylaxis (PP) or secondary prophylaxis (SP) with pegfilgrastim, filgrastim (6-day and 11-day), or no prophylaxis to reduce the risk of febrile neutropenia (FN) in patients with recurrent ovarian cancer receiving docetaxel or topotecan. METHODS A Markov model was used to evaluate the cost-effectiveness of PP vs SP from a US payer perspective. Model inputs, including the efficacy of each strategy (relative risk of FN with prophylaxis compared to no prophylaxis) and mortality, costs, and utility values were estimated from public sources and peer-reviewed publications. Incremental cost-effectiveness was evaluated in terms of net cost per FN event avoided, incremental cost per life-year saved (LYS), and incremental cost per quality-adjusted life-year (QALY) gained over a lifetime horizon. Deterministic and probabilistic sensitivity analyses (DSA and PSA) were conducted. RESULTS For patients receiving docetaxel, the incremental cost-effectiveness ratio (ICER) for PP vs SP with pegfilgrastim was $7900 per QALY gained, and PP with pegfilgrastim dominated all other comparators. For patients receiving topotecan, PP with pegfilgrastim dominated all comparators. Model results were most sensitive to baseline FN risk. PP vs SP with pegfilgrastim was cost effective in 68% and 83% of simulations for docetaxel and in >99% of simulations for topotecan at willingness-to-pay thresholds of $50,000 and $100,000 per QALY. CONCLUSIONS PP with pegfilgrastim should be considered cost effective compared to other prophylaxis strategies in patients with recurrent ovarian cancer receiving docetaxel or topotecan with a high risk of FN.

Abstract
OBJECTIVE To compare the therapeutic effects and adverse reactions of pemetrexed and docetaxel as salvage chemotherapy in patients with nonsmall-cell lung cancer (NSCLC) after the failure of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI). METHODS In this randomized Phase 2 trial, patients with NSCLC who had previously failed EGFR-TKI therapy were randomized to receive intravenous pemetrexed (500 mg/m(2) for 21 days [one cycle]) or docetaxel (75 mg/m(2) for 21 days [one cycle]). Therapeutic effects were evaluated according to Response Evaluation Criteria in Solid Tumours standards and adverse effects were evaluated according to the US National Cancer Institute Common Terminology Criteria for Adverse Events. RESULTS There was no statistically significant difference in disease control rate, response rate, median survival and 1-year survival between treatment groups. Rates of nausea, myelosuppression, renal damage and hair loss were significantly higher in the docetaxel group than the pemetrexed group. CONCLUSION Pemetrexed is effective and well tolerated as salvage chemotherapy in patients with NSCLC after EGFR-TKI failure and may be a suitable therapeutic option in these patients.

Abstract
OBJECTIVE Angiosarcoma is a rare malignant neoplasm with a poor prognosis. A retrospective study was performed to accumulate radiotherapy (RT) data. METHODS Data from 17 patients with angiosarcoma of the face and scalp (AFS) who were treated with definitive RT between January 1999 and July 2011 were retrospectively analysed. The total radiation dose was 70 Gy, and the fractional doses were 2.0-2.5 Gy. Combined with RT, chemotherapy using docetaxel alone, recombinant interleukin-2 immunotherapy alone and both of these was performed in 10, 4 and 2 patients, respectively. Three patients underwent limited surgery before RT. RESULTS The response rate was 82%, and the median overall survival (OS) rate was 26 months. Locoregional relapse alone, distant metastasis alone and both of these were confirmed in 4, 5 and 4 patients, respectively. Patients treated with docetaxel showed a better prognosis (p=0.0477), a distant metastasis-free rate (p=0.0063) and a better in-field control rate, although the last was not statistically significant (p=0.1645). CONCLUSION Definitive RT combined with docetaxel chemotherapy provided an effective approach for treating AFS. ADVANCES IN KNOWLEDGE Since patients treated with chemoradiotherpy using docetaxel showed better OS and distant metastasis-free rates than those who did not receive docetaxel, it was warranted to continue use of docetaxel. In chemoradiotherapy at a dose of 70 Gy using docetaxel, 2-year in-field control rate was 67%.

Abstract
Primary fallopian tube carcinoma (PFTC) is a rare gynaecological tumour that accounts for 0.14-1.8% of genital malignancies. The most common age of occurrence is between 40 and 65 years, and the mean age is 55 years. The factors that contribute to its appearance are not well known. Population studies show that the mean incidence of PFTC is 3.6 per million women per annum. Overall survival percentages for patients with PFTC are generally low, in the range of 22-57%. Pre-operative diagnosis is rare and PFTC is usually confirmed by a pathologist, but earlier diagnosis with early clinical manifestation and prompt investigation improves the prognosis. Both PFTC and epithelial ovarian cancer (EOC) are treated with similar surgical and chemotherapy methods. Studies have shown that the prognosis for PFTC is worse than that for EOC or other primary gynaecological tumours. This article reviews and presents the current updates of this rare gynaecological malignancy.

Abstract
The standard treatment of advanced ovarian cancer is rapidly changing. As we begin to understand that epithelial ovarian cancer is a heterogeneous disease, our treatment strategies are evolving to include novel biologic drugs that specifically exploit altered pathways. Surgery remains an essential component in the treatment of ovarian cancer; however, the importance of surgical specialization and defining "optimal cytoreduction" as no visible residual disease has been further validated. Ongoing studies are defining the role of neoadjuvant chemotherapy in the upfront treatment of advanced ovarian cancer. In addition, clinical trials are evaluating intraperitoneal, dose dense, antiangiogenic drugs as well as targeted maintenance therapies which will establish new standards of care in the near future.

Abstract
The current knowledge and recommendations on the clinical use of granulocyte colony-stimulating factors (G-CSF) in gynecologic cancers including breast cancer, along with the clinical experience of the members of the working group of the Austrian Arbeitsgemeinschaft für Gynäkologische Onkologie (AGO), have been summarized. G-CSF is either administered as primary or secondary prophylaxis of febrile neutropenia. The term "primary prophylaxis" denotes the prophylactic use of G-CSF as early as during the first cycle of a new chemotherapeutic regimen. Secondary prophylaxis, on the other hand, defines the use of G-CSF after development of grade 4 neutropenia or febrile neutropenia in a preceding cycle of a particular chemotherapeutic regimen. When chemotherapy regimens are associated with a > 20 % risk of febrile neutropenia such as TAC (docetaxel-doxorubicin-cyclophosphamide), primary prophylaxis with G-CSF is indicated. When chemotherapy regimens are associated with a 10-20 % risk of febrile neutropenia, the decision for primary prophylaxis with G-CSF is based upon patient-related risk factors such as age > 65 years, previous cytotoxic treatment(s) and/or radiation therapy, preexisting tumor-related neutropenia or bone marrow involvement, preexisting neutropenia, infections/open sores, reduced Karnofsky performance status/WHO performance status and reduced nutritional status, advanced malignant disease, history of prior febrile neutropenia, impaired kidney function, and hepatic failure particularly with hyperbilirubinaemia. The patient's individual overall febrile neutropenia risk should be assessed prior to each chemotherapy cycle.

Abstract
OBJECTIVES On the basis of reversal of taxane resistance with AKT inhibition, we initiated a phase I trial of the AKT inhibitor perifosine with docetaxel in taxane and platinum-resistant or refractory epithelial ovarian cancer. METHODS Patients with pathologically confirmed high-grade epithelial ovarian cancer (taxane resistant, n=10; taxane refractory, n=11) were enrolled. Peripheral blood samples and tumor biopsies were obtained and (18)F-FDG-PET and DCE-MRI scans were performed for pharmacodynamic and imaging studies. RESULTS Patients received a total of 42 treatment cycles. No dose-limiting toxicity was observed. The median progression-free survival and overall survival were 1.9 months and 4.5 months, respectively. One patient with a PTEN mutation achieved a partial remission (PR) for 7.5 months, and another patient with a PIK3CA mutation had stable disease (SD) for 4 months. Two other patients without apparent PI3K pathway aberrations achieved SD. Two patients with KRAS mutations demonstrated rapid progression. Decreased phosphorylated S6 correlated with (18)F-FDG-PET responses. CONCLUSIONS Patients tolerated perifosine 150 mg PO daily plus docetaxel at 75 mg/m(2) every 4 weeks. Further clinical evaluation of effects of perifosine with docetaxel on biological markers and efficacy in patients with ovarian cancer with defined PI3K pathway mutational status is warranted.

Abstract
BACKGROUND The aim of this phase II study was to evaluate the efficacy and toxicity of docetaxel and irinotecan combination chemotherapy in patients with ovarian cancer refractory and resistant to both platinum and taxan treatment. PATIENTS AND METHODS Patients who had been treated with platinum and paclitaxel but whose ovarian cancer progressed or recurred within 6 months of treatment (n = 41) received docetaxel 60 mg/m(2) (day 1) and irinotecan 60 mg/m(2) (days 1, 8), repeated every 21 days [Japan Gynecologic Oncology Group (JGOG) study 3015] or every 28 days [West Japan Gynecologic Oncology Group (WJGOG) study 002] until disease progression was observed or unacceptable toxicity. Sixteen patients had platinum/paclitaxel-refractory disease, and 25 patients had platinum/paclitaxel-resistant disease. RESULTS Thirty-two patients were available for determination of the clinical response. The overall response rate [complete response (CR) + partial response (PR)] was 6.3%, and the disease control rate (CR + PR + stable disease) was 34.4%. Among the 23 patients with resistant tumor, the disease control rate was 47.8%. Ten patients with refractory tumor showed a 10% disease control rate. The median progression-free interval was 12.1 weeks and the median overall survival time was 45.3 weeks. The major toxic adverse effect was neutropenia (grade 4, 56.1%), but the incidence of neutropenic fever was less frequent (4.9%). Neurotoxicity and gastro-intestinal toxicity were mild. CONCLUSION Among our patients, a combination of docetaxel and irinotecan was well tolerated. However, this combination may not be a beneficial option for patients with platinum-refractory and -resistant ovarian cancer in terms of response rate and survival.

Abstract
OBJECTIVES The aim of this study was to determine the maximum tolerated dose and dose-limiting toxicity (DLT) of whole abdomen radiation as a chemosensitizer of weekly docetaxel for women with recurrent epithelial ovarian fallopian tube, or peritoneal cancers. PATIENTS AND METHODS Women were enrolled on one of three dose levels of docetaxel (20, 25, or 30 mg/m(2)) administered weekly with concurrent low-dose whole abdominal radiation given as 60 cGy bid 2 days weekly for a total of 6 weeks. RESULTS Thirteen women were enrolled and received 70 weekly treatments of docetaxel in combination with radiation therapy. At the first dose level, docetaxel 25mg/m(2), grade 3 fatigue and thrombocytopenia were observed. At the next dose level, docetaxel 30 mg/m(2), grade 3 febrile neutropenia, grade 4 thrombocytopenia with epistaxis, and grade 3 diarrhea were observed. Given these dose-limiting toxicities, a lower dose of docetaxel 20mg/m(2) was administered and found to be tolerable. No objective responses were observed among the 10 patients with measurable disease; however, the median progression-free survival (PFS) in all patients was 3.3 months, and 3 of the patients with measurable disease were free of tumor progression after 6 months (30%; 90% confidence interval 8.7-61%). CONCLUSIONS Twice weekly low-dose whole abdomen radiation during weekly docetaxel 20 mg/m(2) was well-tolerated. Given the PFS demonstrated in these women with resistant ovarian cancer, further study of whole abdominal radiation and concurrent chemotherapy may be warranted.

Abstract
Chemotherapy-induced neutropenia is a major risk factor for infection-related morbidity and mortality and also a significant dose-limiting toxicity in cancer treatment. Patients developing severe (grade 3/4) or febrile neutropenia (FN) during chemotherapy frequently receive dose reductions and/or delays to their chemotherapy. This may impact the success of treatment, particularly when treatment intent is either curative or to prolong survival. In Europe, prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs), such as filgrastim (including approved biosimilars), lenograstim or pegfilgrastim is available to reduce the risk of chemotherapy-induced neutropenia. However, the use of G-CSF prophylactic treatment varies widely in clinical practice, both in the timing of therapy and in the patients to whom it is offered. The need for generally applicable, European-focused guidelines led to the formation of a European Guidelines Working Party by the European Organisation for Research and Treatment of Cancer (EORTC) and the publication in 2006 of guidelines for the use of G-CSF in adult cancer patients at risk of chemotherapy-induced FN. A new systematic literature review has been undertaken to ensure that recommendations are current and provide guidance on clinical practice in Europe. We recommend that patient-related adverse risk factors, such as elderly age (≥65 years) and neutrophil count be evaluated in the overall assessment of FN risk before administering each cycle of chemotherapy. It is important that after a previous episode of FN, patients receive prophylactic administration of G-CSF in subsequent cycles. We provide an expanded list of common chemotherapy regimens considered to have a high (≥20%) or intermediate (10-20%) risk of FN. Prophylactic G-CSF continues to be recommended in patients receiving a chemotherapy regimen with high risk of FN. When using a chemotherapy regimen associated with FN in 10-20% of patients, particular attention should be given to patient-related risk factors that may increase the overall risk of FN. In situations where dose-dense or dose-intense chemotherapy strategies have survival benefits, prophylactic G-CSF support is recommended. Similarly, if reductions in chemotherapy dose intensity or density are known to be associated with a poor prognosis, primary G-CSF prophylaxis may be used to maintain chemotherapy. Clinical evidence shows that filgrastim, lenograstim and pegfilgrastim have clinical efficacy and we recommend the use of any of these agents to prevent FN and FN-related complications where indicated. Filgrastim biosimilars are also approved for use in Europe. While other forms of G-CSF, including biosimilars, are administered by a course of daily injections, pegfilgrastim allows once-per-cycle administration. Choice of formulation remains a matter for individual clinical judgement. Evidence from multiple low level studies derived from audit data and clinical practice suggests that some patients receive suboptimal daily G-CSFs; the use of pegfilgrastim may avoid this problem.

Abstract
Manifestations of non-equilibrium polarity, random transgressions, and catastrophes are not conditions usually associated with a sense of normalcy. Yet these disquieting features distinguish a utilitarian behavior known as dynamic instability, the signature characteristic of the microtubule. Long known to be a tumor target, disruption of this fragile attribute is associated with some of the most effective agents used to treat breast cancer today. Although the biology of the microtubule is under intense investigation much still remains unknown. As such, our understanding of regulatory molecules and resistance mechanisms are still rudimentary, further compromising our ability to develop novel therapeutic strategies to improve microtubule inhibitors. This review focuses on several classes of anti-microtubule agents and their effects on the functional dynamics of the targeted polymer. The primary objective is to critically examine the molecular mechanisms that contribute to tumor cell death, tumor-resistance, and incident neurotoxicity.

Abstract
BACKGROUND Data from US Oncology Adjuvant Trial 9735 has shown that four cycles of docetaxel plus cyclophosphamide (TC) improved disease-free and overall survival when compared against doxorubicin and cyclophosphamide (AC) in early-stage breast cancer. The febrile neutropenia (FN) rate was 4% in this study without primary granulocyte colony-stimulating factors (G-CSF) prophylaxis. However, the incidence of docetaxel-induced myelosuppression is recognized to be higher among Asian population. Hence, this study was designed to evaluate the impact of G-CSF to reduce FN-related events in Asian cancer patients treated with TC. METHOD This retrospective cohort study was conducted on Asian breast cancer patients who have received intravenous docetaxel 75 mg/m(2) and cyclophosphamide 600 mg/m(2) between 2006 to 2008. Patients did not receive oral antibiotic prophylaxis, and prophylactic G-CSF after chemotherapy was prescribed under the discretion of the primary oncologist. RESULTS During cycle 1 of chemotherapy, 6.3% patients received G-CSF manifested FN, while 25% patients who did not receive G-CSF manifested FN (RR = 0.252, 95% CI 0.102 to 0.622). Introduction of G-CSF as primary prophylaxis provided an absolute risk reduction of FN events by 18.7%. Chemotherapy doses were maintained throughout all cycles. Patients with pretreatment white blood cell counts (WBC) below 6.0 × 10(3)/mm(3) and absolute neutrophil counts (ANC) below 3.1 × 10(3)/mm(3) were associated with higher rates of FN during Cycle 1 (p = 0.009, p = 0.007). CONCLUSIONS Our findings indicate that TC was associated with higher rates of FN than reported in the clinical trial. The 25% incidence fulfills the requirement of primary prophylaxis with G-CSF. Routine administration of G-CSF is highly recommended to reduce the rates of FN in breast cancer patients receiving TC.

Abstract
The involvement of tubulin mutations as a cause of clinical drug resistance has been intensely debated in recent years. In the studies described here, we used transfection to test whether beta1-tubulin mutations and polymorphisms found in cancer patients are able to confer resistance to drugs that target microtubules. Three of four mutations (A185T, A248V, R306C, but not G437S) that we tested caused paclitaxel resistance, as indicated by the following observations: (a) essentially 100% of cells selected in paclitaxel contained transfected mutant tubulin; (b) paclitaxel resistance could be turned off using tetracycline to turn off transgene expression; (c) paclitaxel resistance increased as mutant tubulin production increased. All the paclitaxel resistance mutations disrupted microtubule assembly, conferred increased sensitivity to microtubule-disruptive drugs, and produced defects in mitosis. The results are consistent with a mechanism in which tubulin mutations alter microtubule stability in a way that counteracts drug action. These studies show that human tumor cells can acquire spontaneous mutations in beta1-tubulin that cause resistance to paclitaxel, and suggest that patients with some polymorphisms in beta1-tubulin may require higher drug concentrations for effective therapy.

Abstract
OBJECTIVES Taxanes have reported response rates of 20% to 40% in recurrent ovarian cancer (ROC) but are less well studied as a later-line treatment. We reviewed our experience with taxanes in ROC to determine (1) if a taxane-free interval is associated with response rates in women with ROC and (2) if the use of intervening therapy (IT) affects subsequent response rates to taxanes. METHODS We retrospectively identified women who received first- or second-line platinum-taxane therapy and later received a single-agent taxane. Demographics, intervening regimens, and follow-up and survival data were collected. Responses were characterized by cancer antigen 125 levels based on the Gynecologic Cancer InterGroup serologic response definitions. RESULTS We identified 46 women who met the eligibility criteria. The median age was 57 years (range, 39-78 years). The median interval between taxanes was 25.8 months (range, 2.9-85.5 months), with 10 (21%) of the women were treated 12 months or less from their last taxane and 37 (79%) treated more than 12 months. The median number of IT was 2 (range, 0-5). Forty patients (87%) received paclitaxel; 6 (13%) received docetaxel. All patients treated 12 months or less from their last taxane responded (P = 0.02). The number of IT was associated with a better response; all women (100%) treated who had no IT, 7 (54%) of 13 women with 1 to 2 ITs, and 7 (39%) of 18 women with 3 ITs or more responded. The overall survival was 13.4 months in responders versus 10.6 months in nonresponders (P = 0.27). CONCLUSIONS Taxanes maintain an activity as a later-line agent, even with 3 or more intervening therapies. However, the highest responses were seen if taxanes were used within 12 months of the last platinum-based combination. The lack of an increased response with aprolonged taxane-free interval is likely related to the number of IT, consistent with the emergence of multidrug resistance.

Abstract
Computer-based theoretical calculations were employed to direct the design of docetaxel conjugates with enhanced solubility in the internal phase of a nano-emulsion formulation. The theoretically-identified optimal docetaxel conjugates were synthesized by direct attachment of lauroyl moieties through an ester linkage to docetaxel. In comparison to docetaxel, the conjugates exhibited significantly improved solubility in oil, as predicted by our theoretical calculations. This contributed to high drug entrapment efficiencies (up to 97%) and a high drug loading capacity (5.7% w/w) for the docetaxel conjugates. The mono-substitution of an acyl group at C-2' of docetaxel resulted in a conjugate with 37- to 46-fold lower cytotoxicity than that of the parent drug in two human cancer cell lines. Importantly, the activity exerted by the mono-substituted docetaxel on the cancer cells was due in part to the cytotoxicity of the parent drug that was released via hydrolysis of the ester bond between the lauroyl moiety and the drug under biologically relevant conditions. In contrast, di- and tri-substitution of acyl groups at C-2', C-7 and/or C-10 of docetaxel resulted in non-hydrolysable conjugates that were found to be inactive. Overall, our results show that computer-based theoretical calculation is a promising strategy for guiding the enhancement of material-drug compatibility in formulation development. Also, these studies confirm that chemical modification of docetaxel for enhancement of material-drug compatibility should be limited to mono-substitution at C-2' and result in a prodrug that is hydrolysable at a moderate rate under biologically relevant conditions.

Abstract
The majority of patients who present with epithelial ovarian cancer respond well to the initial treatment, but will ultimately experience a recurrence of their disease. Chemotherapy can palliate symptoms of disease recurrence, and there is some evidence that it also can improve survival. Recurrent ovarian carcinoma is divided into two subsets of patients: those with platinum-sensitive disease and those with platinum-resistant disease. Management for these two groups has diverged in the last few years, as evidence accrues that the response to treatment and duration of treatment-free interval after completion of front-line therapy impacts the prognosis and the treatment choice for these patients. Recent randomized trials have demonstrated a benefit for platinum combination re-treatment in patients with platinum-sensitive disease. Additionally, there are multiple single-agent trials evaluating novel agents for patients with platinum-resistant as well as platinum-sensitive disease. This review will discuss the role of chemotherapy in recurrent disease, describe the various agents used in this setting, and touch on the role of biologic agents in recurrent epithelial ovarian carcinoma.

Abstract
Over recent decades, truly impressive progress has been made in the outcome associated with the pharmacological antineoplastic management of women with advanced ovarian cancer. Following initial surgery, the large majority of patients with this malignancy will receive a chemotherapy regimen that includes a platinum drug (carboplatin or cisplatin) and a taxane (paclitaxel or docetaxel). Currently, objective responses are observed in approximately 60-80% of patients treated in the front-line setting, with documented improvements in overall survival compared with prior non-platinum and taxane programmes. Unfortunately, despite the high response rate to initial chemotherapy, the majority of women with advanced disease will experience recurrence of the malignant process and be candidates for a variety of possible second-line therapeutic options. It is well recognized that ovarian cancer patients who are documented to experience an initial response to platinum-based chemotherapy but where the disease recurs approximately 6 or more months following the completion of primary therapy, may have another clinically meaningful response (both objective and subjective) to a second platinum-based strategy. However, an optimal management approach in this setting remains to be defined. Furthermore, the malignant cell populations in all ovarian cancer patients who experience an initial relapse of the disease process will eventually be resistant to the platinum agents. In this setting, multiple drugs have been shown to be biologically active. Again, an optimal strategy to be employed in the platinum-resistant setting has yet to be demonstrated through the conduct of evidence-based trials. Reasonable goals of therapy in women with recurrent or resistant ovarian cancer are to improve overall survival, reduce the severity (and delay the occurrence) of symptoms and optimize overall quality of life.

Abstract
BACKGROUND Ovarian tumors frequently express c-Kit and/or platelet-derived growth factor receptors (PDGFRs). Imatinib mesylate blocks the growth of ovarian cancer cells in vitro and may enhance the activity of chemotherapy. This study was conducted to determine the activity of imatinib in combination with docetaxel in patients with recurrent, platinum-resistant epithelial ovarian cancer (EOC). METHODS Eligible patients had recurrent, platinum-resistant, or refractory EOC that expressed PDGFRalpha or c-kit, as determined by immunohistochemistry. Imatinib mesylate at a dose of 600 mg orally once daily was administered continuously with docetaxel at a dose of 30 mg/m(2) given intravenously once weekly in Weeks 1 through 4 of every 6-week cycle. The primary endpoint was objective response rate (ORR) as assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). RESULTS Thirty-four patients were screened for PDGFRalpha and c-kit expression to enroll 23 patients between December 2003 and October 2005. Four patients had c-kit-positive/PDGFR-negative tumors, 11 patients had PDGFR-positive/c-kit-negative tumors, and 8 patients had c-kit-positive/PDGFR-positive tumors. The median patient age was 56 years (range, 33-76 years). Patients had received a median of 3 prior treatments. The ORR was 21.7% and included 1 complete and 4 partial responses. An additional 3 patients had stable disease for more than 4 months. Expression of PDGFR, c-kit, phosphatase and tensin homolog (PTEN), and phosphorylated protein kinase B (Akt) did not predict response to therapy. The most common adverse events encountered were fatigue (83%), nausea (74%), diarrhea (61%), anorexia (52%), and edema (65%), and the majority of those events were graded as grade 1 or 2. CONCLUSIONS The combination imatinib and docetaxel was tolerated in patients with heavily pretreated EOC that expressed c-kit or PDGFRalpha. Few patients had sustained responses or stable disease.

Abstract
Adjuvant chemotherapy reduces risk of relapse and cancer-related mortality in early stage breast cancer. Over the last decade, taxanes (paclitaxel and docetaxel) have been incorporated into various adjuvant trials and have demonstrated a significant benefit in the management of early stage breast cancer. Clinical trials using combinations of taxanes with targeted therapy have also shown considerable activity in breast cancer. This article reviews the pharmacology of docetaxel, a semi-synthetic taxane, and the clinical trials supporting its use in patients with node-positive breast cancer.

Abstract
BACKGROUND Gemcitabine has been recommended as an active agent for salvage chemotherapy in patients with recurrent epithelial ovarian cancer, but no clinical study of this agent has been conducted for Japanese women with ovarian cancer. To evaluate the efficacy and feasibility of gemcitabine for heavily pretreated Japanese patients with recurrent epithelial ovarian cancer, we conducted a single-institute phase II clinical trial. METHODS All patients had received a minimum of two previous chemotherapy regimens, In this study, gemcitabine was administered at 1000 mg/m(2) on days 1, 8, and 15 of a 28-day cycle. RESULTS A total of 28 patients participated in this study. Although 5 patients (17.9%) needed dose reduction to 800 mg/m(2) because of thrombocytopenia and granulocytopenia, all patients completed an average of 6.7 courses (range, 2-24 courses). The overall response rate, including five partial responses, was 17.9% (95% confidence interval [C I], 6.0-36.9). The median time to progression was 8.8 months and the median survival period was 11.2 months. Grade 3/4 hematological toxicities included leucopenia, 35.7%; granulocytopenia, 39.3%; anemia, 46.4%; and thrombocytopenia, 10.7%. However, no grade 3/4 nonhematological toxicity was observed. The mean delay in treatment was 5.0 +/- 7.7 days (range, 0-15 days) in a total of 562 cycles. CONCLUSION Single-agent gemcitabine is an effective salvage chemotherapy regimen in heavily pretreated Japanese patients with recurrent epithelial ovarian cancer.

Abstract
PURPOSE Anthracycline and taxanes are effective agents in advanced breast cancer and prolong survival times. Some patients achieve prolongation of life with capecitabine, gemcitabine, or vinorelbine, even after failure of both anthracycline and taxanes. We analyzed the efficacy and toxicity of gemcitabine and vinorelbine combination chemotherapy in anthracycline- and taxane-pretreated advanced breast cancer. MATERIALS AND METHODS The medical records of anthracycline- and taxane-pretreated metastatic breast cancer patients who received gemcitabine and vinorelbine combination chemotherapy at the Seoul National University Hospital were reviewed. Gemcitabine (1,000 mg/m(2)) and vinorelbine (25 mg/m(2)) were administered intravenously on days 1 and 8 every 3 weeks. RESULTS Between 2000 and 2006, 57 patients were eligible (median age, 45 years), and the median number of previous chemotherapy regimens was 3 (range, 1 approximately 5). The overall response rate was 30% (95% CI, 18.1 approximately 41.9), and the disease control rate was 46% (PR, 30%; SD, 16%). The median duration of follow-up was 33.4 months, the median time-to-progression (TTP) was 3.9 months, and the median overall survival was 10.8 months. None of the patients with patients with anthracycline and taxane primary resistance showed a response and the median TTP for these patients was significantly shorter than that of other patients (1.9 vs. 4.4 months; p=0.018). Although the efficacy was unsatisfactory in patients with both anthracycline and taxane primary resistance, gemcitabine and vinorelbine combination chemotherapy showed comparable efficacy in anthracycline- and/or taxane-sensitive patients and the patients with secondary resistance, even after failure of second-line therapy. Grade 3/4 hematologic toxicities included neutropenia (18.1%) and febrile neutropenia (0.3%), and non-hematologic toxicities were tolerable. CONCLUSION Gemcitabine and vinorelbine combination chemotherapy in anthracycline- and taxane-pretreated advanced breast cancer was effective and tolerable.

Abstract
Objectives. To conduct a drug utilization review (DUR) on the use of granulocyte colony-stimulating factor (G-CSF) and to study the effectiveness of this agent in preventing the incidence of febrile neutropenia (FN). Methods. Outpatients to whom G-CSF was dispensed were identified and their actual medical records were reviewed to verify patients who received G-CSF for primary prophylaxis. Literature was reviewed to determine the expected incidence and risk of FN for chemotherapy regimens used, and the compliance of prescribers with the institutional guidelines was evaluated. After that, the proportion of patients who developed FN was identified and compared to the expected incidence from literature. Data analysis was performed on the outcome of patient-cycle. Results. Of the 99 patient-cycles, 53 (53%) were compliant with guidelines whereas 46 (47%) were not. FN developed in 12 (12.1%, 95% CI = 5.7, 18.5) while the expected average incidence of FN was 32.7%. Eleven (21%, 95% CI = 10.1, 32.2) of the 53 patient-cycles that were compliant with guidelines developed FN, whereas one patient among the non-compliant group developed FN (2%, 95% CI = 0.0, 6.2). The expected incidence of FN was 42.9 and 21.5%, in the compliant group, and noncompliant group, respectively. Based on expected FN rates, the respective reduction in the incidence of FN was 51, and 90%. Conclusions. Lack of adherence to institutional guidelines was noticed in G-CSF prescribing. Reasons behind poor compliance with the guidelines must be verified and resolved. Prophylactic G-CSF is effective in reducing the incidence of FN; however, further research in a larger population is warranted to confirm these findings. J Oncol Pharm Practice (2008) 14: 131—138.

Abstract
The safety and maximum tolerated dose (MTD) of erlotinib with docetaxel/carboplatin were assessed in patients with ovarian cancer. Chemonaive patients received intravenous docetaxel (75 mg m(-2)) and carboplatin (area under the curve 5) on day 1 of a 3-week cycle, and oral erlotinib at 50 (cohort 1), 100 (cohort 2a) or 75 mg day(-1) (cohort 2b) for up to six cycles. Dose-limiting toxicities were determined in cycle 1. Forty-five patients (median age 59 years) received treatment. Dose-limiting toxicities occurred in 1/5/5 patients (cohorts 1/2a/2b). The MTD of erlotinib in this regimen was determined to be 75 mg day(-1) (cohort 2b; the erlotinib dose was escalated to 100 mg day(-1) in 11 out of 19 patients from cycle 2 onwards). Neutropaenia was the predominant grade 3/4 haematological toxicity (85/100/95% respectively). Common non-haematological toxicities were diarrhoea, fatigue, nausea and rash. There were five complete and seven partial responses in 23 evaluable patients (52% response rate). Docetaxel/carboplatin had no measurable effect on erlotinib pharmacokinetics. In subsequent single-agent maintenance, erlotinib was given at 100-150 mg day(-1), with manageable toxicity, until tumour progression. Further investigation of erlotinib in epithelial ovarian carcinoma may be warranted, particularly as maintenance therapy.

Abstract
The taxanes (paclitaxel and docetaxel) currently play an important role in the management of cancers of the ovary, uterus and cervix. In each of these gynecologic malignancies, the drugs are routinely employed in combination with a platinum agent, although when delivered as single agents they may provide substantial palliative benefit. It is important to recognize that despite the documented major utility of this class of agents in the treatment of gynecologic cancers, many highly relevant questions remain, including determining optimal drug delivery schedules, the duration of treatment and the role of regional paclitaxel administration.

Phase II trial of weekly docetaxel for patients with relapsed ovarian cancer who have previously received paclitaxel—ANZGOG 02-01. Gynecol Oncol 2007; 104:647-53. [PMID: 17079006 DOI: 10.1016/j.ygyno.2006.10.006] [Citation(s) in RCA: 16] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2006] [Revised: 09/27/2006] [Accepted: 10/03/2006] [Indexed: 10/24/2022]
Abstract
OBJECTIVE To determine the response rate of weekly docetaxel in women with relapsed epithelial ovarian cancer previously treated with paclitaxel and at least one line of platinum-based chemotherapy. METHODS In this multi-center phase II trial, 37 patients with relapsed disease were enrolled and treated with weekly docetaxel at 35 mg/m for 5 out of 6 consecutive weeks. Two patient cohorts were considered, those who progressed or relapsed within 4 months (N=7) or at greater than 4 months (N=30) from the time of completing their last course of paclitaxel. RESULTS Patients in both cohorts received a median of 2 cycles of treatment (range; 1-4). In evaluable patients, the combined overall response rate, using both CA125 and RECIST response criteria was 18.9% (7/37; 95% CI; 10-34%). The combined overall progression-free survival was 3.1 months (95% CI; 2.5-3.8), and the combined overall survival was 12.3 months (95% CI; 8.2-16.4). Treatment was generally well tolerated with the only grade 4 toxicity being skin toxicity (3%). The most common grade 3 toxicities were fatigue (14%) and watery eyes (8%) with grade 3 neutropenia observed in only 5% of patients. CONCLUSION Weekly docetaxel is well tolerated and has activity in patients with relapsed ovarian cancer previously treated with platinum and paclitaxel.
