Abstract
Abstract
Accurate risk prediction of distant recurrence (DR) is crucial for personalized adjuvant systemic therapy of endometrial cancer (EC) stage I-III patients, as DR is associated with a 5-year overall survival of 10-20%. Risk stratification and treatment recommendation are currently based on histopathological and molecular markers, which is challenging due to high inter-observer variability and testing costs respectively. Deep Learning (DL) models can predict prognosis by identifying relevant visual features from H&E whole slide images (WSIs) at different resolutions without prior assumptions. Here, we developed and tested the first interpretable state-of-the-art DL model for WSI-based risk prediction of DR of stage I-III EC (DeREC) from the randomized PORTEC-1/-2/-3 trials and three clinical cohorts with long-term follow-up data. We used one representative H&E WSI each from 1761 EC patients, excluding those who received adjuvant chemotherapy as it lowers the risk of DR. We randomly sampled 20% as a held-out internal test set (N=353 with 62 events; 8.45 year median follow-up) and performed a 5-fold cross-validation on the training set (N=1408). WSIs were partitioned into 360 micron patches at 40x magnification. DeREC combined self-supervised representation learning of patches using a multi-resolution vision transformer and a WSI-level graph attention-based time-to-event prediction model. The model performance of correctly ranking patients by predicted risk scores and true time to DR was measured with the concordance-index and compared with a Cox’ Proportional Hazards (CPH) model fitted on histopathological variables (histotype, grade, lymphovascular space invasion, stage). Discriminative quality of the predicted risk groups was investigated with Kaplan-Meier analysis and the log-rank test. Most predictive patches by predicted risk groups were reviewed by an expert gynecopathologist for identification of prognostic morphological features. DeREC achieved a concordance-index of 0.764 [95%CI 0.754-0.773] on 5-fold cross validation and 0.757 on the test set, as compared to 0.704 [95%CI 0.662-0.746] with CPH. Predicted risk groups around quartiles 1 and 3 accurately stratified patients between low (N=89), intermediate (N=175), high (N=89) risk of DR (p<0.0001). Among the predicted low-risk group only 3 (3.37%) patients relapsed whereas intermediate and high-risk groups counted 27 (15.43%) and 32 (35.96%) events respectively. DeREC is the first DL model accurately distinguishing EC patients at high risk of DR from those at low risk using one H&E WSI, which would aid decisions on adjuvant treatment. DeREC outperformed standard statistical prediction methods using histopathological variables, indicating that it identified prognostic visual features which can be further investigated. Future development includes the integration of clinicopathological and molecular information.

Abstract
BACKGROUND Endometrial cancer can be molecularly classified into POLEmut, mismatch repair deficient (MMRd), p53 abnormal (p53abn), and no specific molecular profile (NSMP) subgroups. We aimed to develop an interpretable deep learning pipeline for whole-slide-image-based prediction of the four molecular classes in endometrial cancer (im4MEC), to identify morpho-molecular correlates, and to refine prognostication. METHODS This combined analysis included diagnostic haematoxylin and eosin-stained slides and molecular and clinicopathological data from 2028 patients with intermediate-to-high-risk endometrial cancer from the PORTEC-1 (n=466), PORTEC-2 (n=375), and PORTEC-3 (n=393) randomised trials and the TransPORTEC pilot study (n=110), the Medisch Spectrum Twente cohort (n=242), a case series of patients with POLEmut endometrial cancer in the Leiden Endometrial Cancer Repository (n=47), and The Cancer Genome Atlas-Uterine Corpus Endometrial Carcinoma cohort (n=395). PORTEC-3 was held out as an independent test set and a four-fold cross validation was performed. Performance was measured with the macro and class-wise area under the receiver operating characteristic curve (AUROC). Whole-slide images were segmented into tiles of 360 μm resized to 224 × 224 pixels. im4MEC was trained to learn tile-level morphological features with self-supervised learning and to molecularly classify whole-slide images with an attention mechanism. The top 20 tiles with the highest attention scores were reviewed to identify morpho-molecular correlates. Predictions of a nuclear classification deep learning model serve to derive interpretable morphological features. We analysed 5-year recurrence-free survival and explored prognostic refinement by molecular class using the Kaplan-Meier method. FINDINGS im4MEC attained macro-average AUROCs of 0·874 (95% CI 0·856-0·893) on four-fold cross-validation and 0·876 on the independent test set. The class-wise AUROCs were 0·849 for POLEmut (n=51), 0·844 for MMRd (n=134), 0·883 for NSMP (n=120), and 0·928 for p53abn (n=88). POLEmut and MMRd tiles had a high density of lymphocytes, p53abn tiles had strong nuclear atypia, and the morphology of POLEmut and MMRd endometrial cancer overlapped. im4MEC highlighted a low tumour-to-stroma ratio as a potentially novel characteristic feature of the NSMP class. 5-year recurrence-free survival was significantly different between im4MEC predicted molecular classes in PORTEC-3 (log-rank p<0·0001). The ten patients with aggressive p53abn endometrial cancer that was predicted as MMRd showed inflammatory morphology and appeared to have a better prognosis than patients with correctly predicted p53abn endometrial cancer (p=0·30). The four patients with NSMP endometrial cancer that was predicted as p53abn showed higher nuclear atypia and appeared to have a worse prognosis than patients with correctly predicted NSMP (p=0·13). Patients with MMRd endometrial cancer predicted as POLEmut had an excellent prognosis, as do those with true POLEmut endometrial cancer. INTERPRETATION We present the first interpretable deep learning model, im4MEC, for haematoxylin and eosin-based prediction of molecular endometrial cancer classification. im4MEC robustly identified morpho-molecular correlates and could enable further prognostic refinement of patients with endometrial cancer.

Abstract
PURPOSE The randomized Adjuvant Chemoradiotherapy Versus Radiotherapy Alone in Women With High-Risk Endometrial Cancer (PORTEC-3) trial investigated the benefit of combined adjuvant chemotherapy and radiotherapy (CTRT) versus radiotherapy alone (RT) for women with high-risk endometrial cancer (EC). Because The Cancer Genome Atlas defined an EC molecular classification with strong prognostic value, we investigated prognosis and impact of chemotherapy for each molecular subgroup using tissue samples from PORTEC-3 trial participants. METHODS Paraffin-embedded tissues of 423 consenting patients were collected. Immunohistochemistry for p53 and mismatch repair (MMR) proteins, and DNA sequencing for POLE exonuclease domain were done to classify tumors as p53 abnormal (p53abn), POLE-ultramutated (POLEmut), MMR-deficient (MMRd), or no specific molecular profile (NSMP). The primary end point was recurrence-free survival (RFS). Kaplan-Meier method, log-rank test, and Cox model were used for analysis. RESULTS Molecular analysis was successful in 410 high-risk EC (97%), identifying the 4 subgroups: p53abn EC (n = 93; 23%), POLEmut (n = 51; 12%), MMRd (n = 137; 33%), and NSMP (n = 129; 32%). Five-year RFS was 48% for patients with p53abn EC, 98% for POLEmut EC, 72% for MMRd EC, and 74% for NSMP EC (P < .001). The 5-year RFS with CTRT versus RT for p53abn EC was 59% versus 36% (P = .019); 100% versus 97% for patients with POLEmut EC (P = .637); 68% versus 76% (P = .428) for MMRd EC; and 80% versus 68% (P = .243) for NSMP EC. CONCLUSION Molecular classification has strong prognostic value in high-risk EC, with significantly improved RFS with adjuvant CTRT for p53abn tumors, regardless of histologic type. Patients with POLEmut EC had an excellent RFS in both trial arms. EC molecular classification should be incorporated in the risk stratification of these patients as well as in future trials to target specific subgroups of patients.

Abstract
Context ERBB2 (erb-b2 receptor tyrosine kinase 2 or HER2) is currently the only biomarker established for selection of a specific therapy for patients with advanced gastroesophageal adenocarcinoma (GEA). However, there are no comprehensive guidelines for the assessment of HER2 in patients with GEA. Objectives To establish an evidence-based guideline for HER2 testing in patients with GEA, formalize the algorithms for methods to improve the accuracy of HER2 testing while addressing which patients and tumor specimens are appropriate, and to provide guidance on clinical decision making. Design The College of American Pathologists (CAP), American Society for Clinical Pathology (ASCP), and the American Society of Clinical Oncology (ASCO) convened an Expert Panel to conduct a systematic review of the literature to develop an evidence-based guideline with recommendations for optimal HER2 testing in patients with GEA. Results The Panel is proposing 11 recommendations with strong agreement from the open comment participants. Recommendations The Panel recommends that tumor specimen(s) from all patients with advanced GEA, who are candidates for HER2-targeted therapy, should be assessed for HER2 status before the initiation of HER2-targeted therapy. Clinicians should offer combination chemotherapy and an HER2-targeted agent as initial therapy for all patients with HER2-positive advanced GEA. For pathologists, guidance is provided for morphologic selection of neoplastic tissue, testing algorithms, scoring methods, interpretation and reporting of results, and laboratory quality assurance. Conclusion This guideline provides specific recommendations for assessment of HER2 in patients with advanced GEA while addressing pertinent technical issues and clinical implications of the results.

Abstract
Surgical treatment and chemotherapy administration in women with epithelial ovarian cancer is more controversial today than at any point in the last 3 decades. The use of chemotherapy administered intraperitoneally has been particularly contentious. Three large randomized phase III studies, multiple meta-analyses, and now real-world data have demonstrated substantial outcome benefit for the use of chemotherapy administered intraperitoneally versus intravenously for first-line postoperative treatment of optimally debulked advanced ovarian cancer. Unfortunately, for each of these randomized studies, there was scope to either criticize the design or otherwise refute adoption of this route of administration. As a result, the uptake has been variable in North America, although in Europe it has been practically nonexistent. Reasons for this include unquestionable additional toxicity, more inconvenience, and extra cost. However, 10-year follow up of these studies demonstrates unprecedented survival in the intraperitoneal arm (median survival 110 months in patients with completely debulked stage III), raising the possibility that by combining maximal debulking surgery with postoperative intraperitoneal chemotherapy it may be possible to bring about a step change in the outcomes for these patients. In this review, we discuss the rationale for administering chemotherapy intraperitoneally, the merits of the main randomized clinical trials, the evidence regarding optimal regimes, issues of toxicity, port considerations, and reasons for lack of universal adoption. We also explore potential clinical and biologic factors that may be useful for patient selection in the future.

Abstract
Polymorphisms in miRNA and miRNA pathway genes have been previously associated with cancer risk and outcome, but have not been studied in esophageal adenocarcinoma outcomes. Here, we evaluate candidate miRNA pathway polymorphisms in esophageal adenocarcinoma prognosis and attempt to validate them in an independent cohort of esophageal adenocarcinoma patients. Among 231 esophageal adenocarcinoma patients of all stages/treatment plans, 38 candidate genetic polymorphisms (17 biogenesis, 9 miRNA targets, 5 pri‐miRNA, 7 pre‐miRNA) were genotyped and analyzed. Cox proportional hazard models adjusted for sociodemographic and clinicopathological covariates helped assess the association of genetic polymorphisms with overall survival (OS) and progression‐free survival (PFS). Significantly associated polymorphisms were then evaluated in an independent cohort of 137 esophageal adenocarcinoma patients. Among the 231 discovery cohort patients, 86% were male, median diagnosis age was 64 years, 34% were metastatic at diagnosis, and median OS and PFS were 20 and 12 months, respectively. GEMIN3 rs197412 (aHR = 1.37, 95%CI: [1.04–1.80]; P = 0.02), hsa‐mir‐124‐1 rs531564 (aHR = 0.60, 95% CI: [0.53–0.90]; P = 0.05), and KIAA0423 rs1053667 (aHR = 0.51, 95% CI: [0.28–0.96]; P = 0.04) were found associated with OS. Furthermore, GEMIN3 rs197412 (aHR = 1.33, 95% CI: [1.03–1.74]; P = 0.03) and KRT81 rs3660 (aHR = 1.29, 95% CI: [1.01–1.64]; P = 0.04) were found associated with PFS. Although none of these polymorphisms were significant in the second cohort, hsa‐mir‐124‐1 rs531564 and KIAA0423 rs1053667 had trends in the same direction; when both cohorts were combined together, GEMIN3 rs197412, hsa‐mir‐124‐1 rs531564, and KIAA0423 rs1053667 remained significantly associated with OS. We demonstrate the association of multiple miRNA pathway polymorphisms with esophageal adenocarcinoma prognosis in a discovery cohort of patients, which did not validate in a separate cohort but had consistent associations in the pooled cohort. Larger studies are required to confirm/validate the prognostic value of these polymorphisms in esophageal adenocarcinoma.

Abstract
BACKGROUND Genomic alterations that activate the MAPK signaling pathway frequently occur in Type I Epithelial Ovarian Cancers (EOCs). We evaluated therapeutic response outcomes in patients with type I EOC treated with genotype-matched therapy on clinical trials enrolled in a prospective molecular profiling program. MATERIAL AND METHODS Formalin fixed paraffin embedded tumor tissues were prospectively screened for genomic alterations using MALDI-ToF mass-spectrometry platform or targeted sequencing using the Illumina MiSeq TruSeq Amplicon Cancer Panel. Treatment outcomes on genotype-matched trials were retrospectively reviewed using RECIST version 1.1 and Gynecological Cancer Intergroup CA125 related-response criteria RESULTS: 55 patients with type I EOC underwent molecular profiling, 41 (75%) low grade serous (LGS), 9 (16%) clear cell (CC), and 5 (9%) mucinous (MC) histologies. Thirty-five patients (64%) were found to have ≥1 somatic mutations: 23 KRAS, 6 NRAS, 5 PIK3CA, 2 PTEN, 1 BRAF, 1 AKT, 1 TP53, and 1 CTNNB1. Fifteen patients were subsequently enrolled in genotype-matched phase I or II trials, including 14 patients with KRAS/NRAS mutations treated with MEK inhibitor targeted combinations. Among 14 RECIST evaluable patients, there were 7 partial responses (PR), 7 stable disease (SD) and 1 disease progression (PD). CA125 responses were observed in 10/10 evaluable KRAS/NRAS mutant patients treated with MEK inhibitor combinations CONCLUSIONS: Genotyping and targeted sequencing of Type I EOCs frequently identifies actionable mutations. Matched treatment with MEK-based combination therapy in KRAS and/or NRAS mutant type I EOC patients is an active therapeutic strategy.

Abstract
CONTEXT - ERBB2 (erb-b2 receptor tyrosine kinase 2 or HER2) is currently the only biomarker established for selection of a specific therapy for patients with advanced gastroesophageal adenocarcinoma (GEA). However, there are no comprehensive guidelines for the assessment of HER2 in patients with GEA. OBJECTIVES - To establish an evidence-based guideline for HER2 testing in patients with GEA, to formalize the algorithms for methods to improve the accuracy of HER2 testing while addressing which patients and tumor specimens are appropriate, and to provide guidance on clinical decision making. DESIGN - The College of American Pathologists, American Society for Clinical Pathology, and American Society of Clinical Oncology convened an expert panel to conduct a systematic review of the literature to develop an evidence-based guideline with recommendations for optimal HER2 testing in patients with GEA. RESULTS - The panel is proposing 11 recommendations with strong agreement from the open-comment participants. RECOMMENDATIONS - The panel recommends that tumor specimen(s) from all patients with advanced GEA, who are candidates for HER2-targeted therapy, should be assessed for HER2 status before the initiation of HER2-targeted therapy. Clinicians should offer combination chemotherapy and a HER2-targeted agent as initial therapy for all patients with HER2-positive advanced GEA. For pathologists, guidance is provided for morphologic selection of neoplastic tissue, testing algorithms, scoring methods, interpretation and reporting of results, and laboratory quality assurance. CONCLUSIONS - This guideline provides specific recommendations for assessment of HER2 in patients with advanced GEA while addressing pertinent technical issues and clinical implications of the results.

Abstract
Background Carboplatin-based chemotherapy offers high response rates and improved overall survival for women with epithelial ovarian cancer, but its use is limited by the occurrence of hypersensitivity reactions. To evaluate the efficacy of prophylactic diphenhydramine for hypersensitivity reaction prevention, we reviewed the incidence of hypersensitivity reactions and identified patients at high risk of hypersensitivity reactions. Methods Women receiving ≥6 cycles of carboplatin-based chemotherapy for epithelial ovarian cancer were identified from our institutional database at the Princess Margaret Cancer Centre. Institutional policy was changed in 2009 to introduce diphenhydramine prophylaxis for patients receiving ≥6 cycles of carboplatin. Additional clinical data were abstracted from the patient record. Results Between 2006 and 2012, 450 women received ≥6 cycles of carboplatin-based chemotherapy for epithelial ovarian cancer. Two hundred and ninety-one women received prophylaxis with diphenhydramine. Carboplatin-induced hypersensitivity reactions occurred in 41 of 449 patients (9%). Univariable predictors of carboplatin-induced hypersensitivity reactions included administration of 8 to 10 cycles of carboplatin, history of other drug allergies and a platinum-free interval >12 months. BRCA mutational status was not predictive. In a multivariable analysis, the number of cycles of carboplatin and a platinum-free interval >12 months were independent predictors of hypersensitivity reactions. There was a trend towards diphenhydramine prophylaxis reducing the incidence of hypersensitivity reactions in women with a platinum-free interval compared to continuous delivery; this was most marked when the platinum-free interval was >12 months (n = 64) (OR: 0.2 (95% CI: 0.046–0.83), p = 0.03). Conclusions The administration of diphenhydramine to women who have a platinum-free interval may reduce the risk of hypersensitivity reaction, but prospective evaluation is required.

Three large randomized phase III studies, multiple meta-analyses, and now real-world data have demonstrated substantial outcome benefit for the use of chemotherapy administered intraperitoneally versus intravenously for first-line postoperative treatment of optimally debulked advanced ovarian cancer. Unfortunately, for each of these randomized studies, there was scope to either criticize the design or otherwise refute adoption of this route of administration. As a result, the uptake has been variable in North America, although in Europe it has been practically nonexistent. Reasons for this include unquestionable additional toxicity, more inconvenience, and extra cost. However, 10-year follow up of these studies demonstrates unprecedented survival in the intraperitoneal arm (median survival 110 months in patients with completely debulked stage III), raising the possibility that by combining maximal debulking surgery with postoperative intraperitoneal chemotherapy it may be possible to bring about a step change in the outcomes for these patients. In this review, we discuss the rationale for administering chemotherapy intraperitoneally, the merits of the main randomized clinical trials, the evidence regarding optimal regimes, issues of toxicity, port considerations, and reasons for lack of universal adoption. We also explore potential clinical and biologic factors that may be useful for patient selection in the future.

Abstract
INTRODUCTION Epithelial ovarian cancer is the most lethal gynecologic malignancy. Recent advances in understanding the biology and its molecular and histological diversity have led to mechanism based therapeutic strategies such as poly-ADP-ribose polymerase inhibitors (PARP) targeting homologous recombination deficient tumor cells and anti-angiogenic therapies. Clinical trial designs in ovarian cancer have to evolve to incorporate assessment of the genomic complexity and identify predictive biomarkers to improve precision of treatment and outcome. AREAS COVERED This review summarizes present-day strategies used in the management of ovarian cancer and novel promising therapeutic approaches in development. The article is based on English peer-reviewed articles located on MEDLINE and related abstracts presented at major international meetings. EXPERT OPINION Two types of molecular targeted therapies, anti-angiogenics and PARP inhibitors, have been shown to be active in randomized clinical trials and approved by regulatory agencies. Management of ovarian cancer is poised to change with the continued advancement of precision medicine that is founded upon improved understanding of disease biology; separation into histologically and molecularly defined subgroups; and the incorporation of this new knowledge into early phase drug development and novel clinical trial design.

Abstract
Despite the declining incidence of cervical cancer as a result of the introduction of screening programs, globally it remains a leading cause of cancer-related death in women. Outcomes for patients who are diagnosed with anything but early-stage disease remain poor. Here we examine emerging strategies to improve the treatment of locally advanced disease. We discuss emerging biologic data, which are informing our investigation of new therapeutic interventions in persistent, recurrent, and metastatic cervical cancer. We recognize the importance of interventions to improve quality of life and to prevent long-term sequelae in women undergoing treatment. Finally, and perhaps most importantly, we recognize the need for global collaboration and advocacy to improve the outcome for all women at risk of and diagnosed with this disease.

Abstract
In the era of targeted therapies, patients with gynecologic malignancies have not yet been major beneficiaries of this new class of agents. This may reflect the fact that the main tumor types-ovarian, uterine, and cervical--are a highly heterogeneous group of cancers with variable response to standard chemotherapies and the lack of models in which to study the diversity of these cancers. Cancer-derived cell lines fail to adequately recapitulate molecular hallmarks of specific cancer subsets and complex microenvironments, which may be critical for sensitivity to targeted therapies. Patient-derived xenografts (PDX) generated from fresh human tumor without prior in vitro culture, combined with whole genome expression, gene copy number, and sequencing analyses, could dramatically aid the development of novel therapies for gynecologic malignancies. Gynecologic tumors can be engrafted in immunodeficient mice with a high rate of success and within a reasonable time frame. The resulting PDX accurately recapitulates the patient's tumor with respect to histologic, molecular, and in vivo treatment response characteristics. Orthotopic PDX develop complications relevant to the clinic, such as ascites and bowel obstruction, providing opportunities to understand the biology of these clinical problems. Thus, PDX have great promise for improved understanding of gynecologic malignancies, serve as better models for designing novel therapies and clinical trials, and could underpin individualized, directed therapy for patients from whom such models have been established.

Abstract
Despite the introduction of screening and, latterly, vaccination programs in the developed world, globally cervical cancer remains a significant health problem. For those diagnosed with advanced or recurrent disease even within resource rich communities, prognosis remains poor with an overall survival (OS) of just over 12 months. New therapeutic interventions are urgently required. Advances in our understanding of the mechanisms underlying tumor growth and the downstream effects of human papilloma virus (HPV) infection identified angiogenesis as a rational target for therapeutic intervention in cervical cancer. Anti-angiogenic agents showed promising activity in early phase clinical trials culminating in a randomized phase III study of the humanized monoclonal antibody to vascular endothelial growth factor (VEGF), bevacizumab, in combination with chemotherapy. This pivotal study, the Gynecologic Oncology Group protocol 240, met its primary endpoint demonstrating a significant improvement in OS. Bevacizumab became the first targeted agent to be granted regulatory approval by the United States Food and Drug Administration for use alongside chemotherapy in adults with persistent, recurrent or metastatic carcinoma of the cervix. This review outlines the rationale for targeting angiogenesis in cervical cancer focusing on the current indications for the use of bevacizumab in this disease and future directions.

Abstract
PURPOSE A phase II study was performed to evaluate the efficacy and safety of single-agent RO4929097 (a gamma-secretase inhibitor) in patients with recurrent platinum-resistant ovarian cancer. EXPERIMENTAL DESIGN Women with progressive platinum-resistant ovarian cancer treated with ≤2 chemotherapy regimens for recurrent disease were enrolled in this trial. Patients received oral RO4929097 at 20 mg once daily, 3 days on/4 days off each week in a three week cycle. The primary endpoint was progression-free survival (PFS) rate at the end of 4 cycles. Secondary objectives included assessment of the safety of RO4929097 and exploration of molecular correlates of outcome in archival tumor tissue and serum. RESULTS Of 45 patients enrolled, 40 were evaluable for response. Thirty-seven (82%) patients had high-grade ovarian cancer. No objective responses were observed. Fifteen patients (33%) had stable disease as their best response, with a median duration of 3.1 months. The median PFS for the whole group was 1.3 months (1.2-2.5). Treatment was generally well tolerated with 10% of patients discontinuing treatment due to an adverse event. In high grade serous ovarian cancer patients, the median PFS trended higher when the expression of intracellular Notch (NICD) protein by immunohistochemistry was high versus low (3.3 versus 1.3 months, p=0.09). No clear relationship between circulating angiogenic factors and PFS was found despite a suggestion of an improved outcome with higher baseline VEGFA levels. CONCLUSIONS RO4929097 has insufficient activity as a single-agent in platinum-resistant ovarian cancer to warrant further study as monotherapy. Future studies are needed to explore the potential for cohort enrichment using NICD expression.

Abstract
Invasive cervical cancer remains an important global cause of death, despite the declining prevalence within the United States. Definitive therapies, including surgical resection of early-stage disease and chemoradiation for locally advanced disease, can be curative. For women who experience local or distant recurrences, the prognosis remains poor and better treatments are required. On July 18, 2013, The Gynecologic Oncology Group sponsored a State of the Science in Cervical Cancer Symposium with experts, researchers, clinicians, and interested stakeholders. This article summarize the progress that has been made, questions that require further investigation, and contemporary genomic findings and innovative treatments that may help inform the next generation of clinical trials for patients with cervical cancer.

Abstract
BACKGROUND Targeting the phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway is of increasing interest as a therapeutic strategy in many tumors. The aim of this study was to identify molecular markers associated with mTOR inhibitor activity in women with metastatic endometrial cancer. METHODS Archival tumor samples were collected from 94 women with recurrent or metastatic endometrial cancer who participated in 3 National Cancer Insitute of Canada Clinical Trials Group phase 2 trials investigating single-agent mTOR inhibitors: IND160A and IND160B (temsirolimus) and IND192 (ridaforolimus). Analyses included mutational profiling using the OncoCarta Panel version 1.0 and immunohistochemical expression of the tumor suppressor gene PTEN (phosphatase and tensin homologue) and stathmin, a marker of PI3K activation. Associations between biomarker results and clinical outcomes were assessed. RESULTS Mutations were found in 32 of 73 analyzed tumors, PIK3CA (21 patients) was the most common mutated gene. Co-mutations were seen in 8 tumors, most frequently KRAS and PIK3CA (4 cases). PTEN loss was observed in 46 of 85 samples analyzed and increased stathmin expression was observed in 15 of 65 analyzed samples. No correlation was observed between biomarkers and response or progression. In patients taking concurrent metformin, there was a trend toward lower progression, of 11.8% versus 32.5% (P = .14). CONCLUSIONS No predictive biomarker or combination of biomarkers for mTOR inhibitor activity were identified in this study. Restriction and enrichment of study entry, especially based on archival tumor tissue, should be undertaken with caution in trials using these agents.

Abstract
Cervical cancer is the third most common cause of female cancer mortality, and it remains a major health problem in populations with limited economic resources. Metastatic disease or recurrent lesions not amenable to radical local excision or regional radiation have a poor prognosis, and are treated with palliative platinum-based chemotherapy. There are few effective therapeutic options for patients who progressed after first-line chemotherapy. Future advances in the treatment of metastatic or recurrent disease may rely on more effective and better-tolerated therapies, and molecularly driven targeted agents could represent an attractive option. Inhibition of tumor angiogenesis and epidermal growth factor receptor directed therapies have focused the most recent clinical research efforts. A thorough molecular characterization of cervical cancer remains crucial for a rationale implementation of targeted agents and companion biomarkers. Alternative clinical trial designs may also be necessary to optimize the clinical development of new drugs for metastatic cervical cancer.

Abstract
Angiogenesis is an important host process that interacts with cancer cells to promote growth, invasion, and metastasis. Numerous therapeutic agents targeting the VEGF pathway have been developed. Host variability in VEGF pathway can influence angiogenesis-dependent signaling, altering sensitivity to antiangiogenic drugs and prognosis. A systematic review and meta-analysis was conducted (May 1990-July 2011). Eligible studies involved cancer patients and compared polymorphisms in the VEGF pathway [VEGF and molecules directly interacting with VEGF: KDR, FLT1, FGF, FGF2, FGFR, NRP1, endostatin (encoded by COL18A1)], and reported one of the following outcomes: overall survival, progression-free survival, time to recurrence, disease-free survival, response rate, or drug toxicity. We identified 48 cancer studies assessing prognosis and 12 cancer studies exploring pharmacogenetics of anti-VEGF therapy across various VEGF pathway polymorphisms. There was marked inter- and intradisease site heterogeneity in the effect of polymorphisms on both outcome and response to therapy. Meta-analyses of 5 VEGF polymorphisms (+936C>T, -460T>C, +405G>C, -1154G>A, and -2578C>A) identified a significant prognostic relationship: VEGF +405G>C variants showed a highly statistically significant improvement in overall survival [HR, 0.74; 95% confidence interval, 0.60-0.91; P = 0.004]. Variants (heterozygotes and/or homozygotes) of VEGF +405G>C were significantly associated with improved survival in a meta-analysis of multiple cancer sites.

Abstract
OBJECTIVE The aim of this multi-institutional non randomized phase II trial was to determine the efficacy and safety of single agent aflibercept (VEGF Trap), a recombinant fusion protein that blocks multiple vascular endothelial growth factor isoforms, in women with gynecologic soft tissue sarcoma. METHODS Patients were enrolled in two cohorts each with Simon two stage designs: uterine leiomyosarcoma and carcinosarcoma of endometrial, ovarian or fallopian tube origin. Eligibility criteria included ≤2 prior lines of chemotherapy for metastatic disease and ECOG performance status of ≤2. Aflibercept 4mg/kg was administered intravenously on day 1 of a 14 day cycle. Primary endpoints were objective response and disease stabilization (Progression Free Survival (PFS) at 6 months). RESULTS 41 patients with uterine leiomyosarcoma and 22 patients with carcinosarcoma (19 uterine, 3 ovarian) were enrolled on study. In the leiomyosarcoma cohort, eleven (27%) patients had stable disease (SD), 4 with SD lasting at least 24 weeks. The 6 month PFS was 17%, with median time to progression (TTP) of 1.8 (95% CI:1.6-2.1) months. In the carcinosarcoma cohort, two (9%) patients had SD, one lasting >24 weeks, median TTP was 1.6 months (95%CI: 1.1-1.7) No partial responses were observed in patients from either cohort. Grade 3 or more aflibercept related toxicity was uncommon and included hypertension, fatigue, headache and abdominal pain. CONCLUSIONS Single agent aflibercept has modest activity in patients with uterine leiomyosarcoma and minimal activity in women with carcinosarcoma.

Abstract
PURPOSE Phosphatase and tensin homolog (PTEN) is a tumor suppressor gene, and loss of function mutations are common and appear to be important in the pathogenesis of endometrial carcinomas. Loss of PTEN causes deregulated phosphatidylinositol-3 kinase/serine-threonine kinase/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling which may provide neoplastic cells with a selective survival advantage by enhancing angiogenesis, protein translation, and cell cycle progression. Temsirolimus, an ester derivative of rapamycin that inhibits mTOR, was evaluated in this setting. PATIENTS AND METHODS Sequential phase II studies evaluated single-agent activity of temsirolimus in women with recurrent or metastatic chemotherapy-naive or chemotherapy-treated endometrial cancer. Temsirolimus 25 mg intravenously was administered weekly in 4-week cycles. RESULTS In the chemotherapy-naive group, 33 patients received a median of four cycles (range, one to 23 cycles). Of the 29 patients evaluable for response, four (14%) had an independently confirmed partial response and 20 (69%) had stable disease as best response, with a median duration of 5.1 months (range, 3.7 to 18.4 months) and 9.7 months (range, 2.1 to 14.6 months). Only five patients (18%) had progressive disease. In the chemotherapy-treated group, 27 patients received a median of three cycles (range, one to six cycles). Of the 25 patients evaluable for response, one (4%) had an independently confirmed partial response, and 12 patients (48%) had stable disease, with a median duration of 4.3 months (range, 3.6 to 4.9 months) and 3.7 months (range, 2.4 to 23.2 months). PTEN loss (immunohistochemistry and mutational analysis) and molecular markers of PI3K/Akt/mTOR pathway did not correlate with the clinical outcome. CONCLUSION mTOR inhibition with temsirolimus has encouraging single-agent activity in endometrial cancer which is higher in chemotherapy-naive patients than in chemotherapy-treated patients and is independent of PTEN status. The difference in activity according to prior therapy should be factored into future clinical trial designs.

Abstract
Three large randomized clinical trials have shown a survival benefit in women with stage iii epithelial ovarian cancer (eoc) who receive intraperitoneal (IP) chemotherapy after optimal primary debulking surgery. The most recent Gynecologic Oncology Group study, gog 172, showed an improvement in median overall survival of approximately 17 months. That result led to a U.S. National Cancer Institute (nci) clinical announcement recommending that IP chemotherapy be considered for this group of women with eoc. However, IP chemotherapy is associated with increased toxicity, and rates for completion of treatment are low (42% in gog 172). The optimal IP regimen and duration of treatment has yet to be defined. Women undergoing chemotherapy before optimal debulking surgery were not included in the studies or in the nci clinical announcement. The National Cancer Institute of Canada Clinical Trials Group has developed a protocol for a randomized phase ii/iii study which will examine whether IP platinum-taxane-based chemotherapy benefits women who have received neoadjuvant chemotherapy before optimal surgical debulking. To address whether the less systemically toxic carboplatin can be substituted for cisplatin IP, the first phase of the study will have 3 arms: 1 intravenous-only, and 2 IP-containing regimens. At the end of the first stage, and provided that IP therapy is feasible to administer in this patient population, one of the IP regimens, either IP carboplatin or IP cisplatin, will proceed into a phase iii comparison with the intravenous arm. This exciting new study has gathered international support.

Abstract
PURPOSE The Src family of kinases may play a role in the development and progression of gastric cancer. We evaluated the activity and safety of saracatinib an oral, anilinoquinazolone, non-receptor tyrosine kinase inhibitor targeting Src kinases, in patients with metastatic or locally advanced gastric carcinoma. METHODS Eligible patients who had received ≤1 prior line of chemotherapy for metastatic disease received saracatinib 175 mg/day of a 28 day cycle until progression. The primary endpoint was the objective response and/or prolonged stable disease rate (pSD ≥ 16 weeks). RESULTS Ten patients with gastric carcinoma and 11 with adenocarcinoma of the gastroesophageal junction received a median of 2 cycles (range 1-10 cycles) of treatment per patient. 17 patients were evaluable for response. No objective response was seen. One patient experienced prolonged Stable disease (pSD). Three patients had SD and 13 progressive disease. Median overall survival was 7.8 months (95% CI, 3.9-12.2 months) and median time to progression was 1.8 months (95% CI: 1.5-1.9 months). Grade 3 events possibly related to saracatinib included: fatigue (2 patients), hypoxia (2) anemia (3) and lymphopenia (2). CONCLUSION Saracatinib has insufficient activity as a single agent in patients with advanced gastric adenocarcinoma to warrant further investigation. Further development in gastric cancer would require rational drug combinations or identification of a tumor phenotype sensitive to Src inhibition.

Abstract
BACKGROUND Over 85% of healthy individuals vaccinated with the pandemic H1N1 (pH1N1) vaccine achieve seroprotection. OBJECTIVES We evaluated the safety and immunogenicity of pH1N1 vaccine in patients undergoing chemotherapy for hematological and solid tumor malignancies. STUDY DESIGN Adult patients, receiving chemotherapy undergoing pH1N1 vaccination at our institution had blood samples drawn for CBC (baseline only) and serology prior to and ≥ 21 days post vaccination. HAI antibody testing was performed for pH1N1 (A/California/7/2009 strain) and seasonal H1 (A/Brisbane/59/07 strain). Seroprotection was defined as a pH1N1 antibody titre ≥ 1:40 and seroconversion as an antibody titre >4 × baseline. Patients completed a symptom diary card. RESULTS Paired samples were available for 46 patients (20 solid tumor, 26 hematological), median age 56 (range 23-76) years. The seroprotective rate post-vaccination for solid tumors was 50% compared to 27% for hematological malignancy (p=0.11), respective seroconversion rates were 45% and 19% (p=0.06). In patients with solid tumors vaccination mid cycle resulted in the highest pH1N1 titres, although timing and blood count were not associated with seroconversion or seroprotection. For hematological patients, a normal leukocyte count and vaccination at the beginning of a cycle were associated with higher rates of seroconversion (p ≤ 0.05). Addition of rituximab to chemotherapy resulted in a failure to seroconvert (p=0.05). Vaccination was well tolerated by all patients. CONCLUSIONS Although well tolerated, the seroprotection rate following pH1N1 vaccination is lower than that would be expected. Further investigation into immunization strategies in patients receiving chemotherapy is required.

Abstract
BACKGROUND The prognostic relevance of uncommon epithelial ovarian cancer (EOC) histological subtypes remains controversial. The Gynecologic Cancer InterGroup (GCIG) initiated this meta-analysis to assess the relative prognosis of women with a diagnosis of rare EOC histologies from completed, prospectively randomized studies performed by cooperative GCIG study groups. METHODS Studies eligible for analysis included first-line treatment of at least 150 patients with stage III/IV EOC treated with a platinum/taxane-based regimen. Collaborating groups were to provide patient-level data. Serous acted as the reference histology, and a proportional hazards model was used to estimate the relative rate of progression or death. RESULTS Data on 8704 women with stage III/IV EOC from 7 randomized trials were included in these analyses. Two hundred twenty-one patients (2.5%) had clear cell carcinoma; 264 (3.0%), mucinous; and 36 (0.4%), transitional cell. The mean age of patients with serous histology was greater than those with mucinous (4.1 years) and clear cell (2.6 years, P < 0.001). Mucinous, clear cell, and transitional cell tumors were more likely to be completely resected than serous (P < 0.05). When controlling for age and residual disease, mucinous and clear cell tumors had shorter times to progression (hazards ratio [HR], 2.1; 95% confidence interval [CI], 1.8-2.4 and HR, 1.6; 95% CI, 1.4-1.9, respectively) and death (HR, 2.7; 95% CI, 2.3-3.1 and HR, 2.2; 95% CI, 1.8-2.6, respectively) compared with serous. The median overall survival for serous, clear cell, mucinous, and endometrioid histologies were 40.8, 21.3, 14.6, and 50.9 months. CONCLUSIONS Mucinous and clear cell carcinomas are independent predictors of poor prognosis in stage III/IV EOC. Studies targeting these rare histological subtypes are warranted and will require significant intergroup collaboration.

Abstract
AIM Micropapillary/borderline (LMP) ovarian tumours are rarely included in clinical trials and are intrinsically resistant to radiation and chemotherapy. Platinum resistant epithelial ovarian cancer (EOC) has a poor prognosis. The histone deacetylase inhibitor belinostat demonstrated antitumour activity in pre-clinical ovarian cancer models. METHODS A phase II study was performed to evaluate the activity of belinostat in two patient populations: women with metastatic or recurrent platinum resistant (progression within 6 months) EOC and LMP ovarian tumours, both groups had received no more than 3 prior lines of chemotherapy. Belinostat 1000 mg/m(2)/d was administered iv days 1-5 of a 21 d cycle. Peripheral blood mononuclear cells (PBMCs) and tumour biopsies, where possible, for correlative studies were obtained prior to and following treatment. RESULTS Eighteen patients with EOC and 14 patients with LMP tumours were enrolled on study. Belinostat was well tolerated with no grade four toxicity (179 cycles). Grade 3 toxicity consisted of thrombosis (3 patients), hypersensitivity (1) and elevated ALP (1). One patient with LMP tumour had a partial response (unconfirmed) and 10 had stable disease (SD), 3 were non-evaluable. Median progression-free survival (PFS) was 13.4 months (95% confidence interval (CI), 5.6--not reached). Best response in patients with EOC was SD (nine patients) and median PFS was 2.3 months (95% CI, 1.2-5.7 months). An accumulation of acetylated histones H3 and H4 was noted in PBMCs and in tumour tissue. CONCLUSIONS Belinostat is well tolerated in both patient groups and shows some activity in patients with micropapillary (LMP) disease.

Abstract
AIM The impact of PTEN status and microsatellite instability (MSI) on the prognosis of women with endometrial cancer is controversial. The aim of this study was to investigate MSI and PTEN expression in two patient populations using data from NCIC CTG studies. METHODS Archival paraffin embedded tumour from women with endometrial cancer enrolled in NCIC CTG studies: EN5 (stage I/II) and IND 126, 148 and 160 (advanced/recurrent disease) were examined for MSI using BAT25/26 and for PTEN expression using immunohistochemistry. PTEN and MSI status were correlated with clinicopathologic variables and survival using data from NCIC CTG trial databases. RESULTS PTEN and MSI results were available from 128 and 163 patients, respectively. MSI+ tumours were more common in women enrolled in EN5 compared to the IND studies (p=0.01). PTEN negative tumours were associated with improved survival in both univariate (hazard ratio (HR) 0.55, 95% confidence interval (CI) 0.32-0.94; p=0.03) and multivariate (adjusted HR 0.54, 95% CI 0.30-0.96; p=0.03) analyses in women enrolled in IND studies. Microsatellite stable tumours were associated with an improved prognosis in univariate (HR 0.18, 95% CI 0.06-0.51; p<0.0001) and multivariate (adjusted HR 0.16, 95% CI 0.05-0.5; p<0.0001) analyses in women enrolled in EN5. There was no significant correlation between MSI and PTEN status. CONCLUSIONS PTEN negative tumours in women with advanced disease are associated with improved survival. MSI+ tumours are more common in early stage disease and in this group of women are associated with a worse prognosis.

Abstract
Despite improvements in surgical and diagnostic techniques, the outcome for women with advanced epithelial ovarian cancer remains poor. Recent developments in the understanding of cancer biology have led to an explosion in clinical trials using targeted agents. In women with epithelial ovarian cancer, antiangiogenic agents have led the field. There are, however, other novel targets and agents undergoing evaluation. This review focuses on some of these newer approaches to targeted therapy highlighting the importance of trial design and incorporation of biomarkers as we move forward into the era of personalized medicine.

Abstract
PURPOSE The DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (decitabine) induces DNA demethylation and re-expression of epigenetically silenced genes, and increases carboplatin sensitivity of tumor xenograft models. We designed a clinical study to determine the feasibility of delivering a dose of decitabine, combined with carboplatin, that would be capable of producing equivalent biologic effects in patients with solid tumors. PATIENTS AND METHODS In a two-stage design, 33 patients received escalating doses of decitabine administered as a 6-hour infusion on day 1 followed by carboplatin, area under the concentration-time curve (AUC) 5 (cohort 1) and AUC 6 (cohort 2), on day 8 of a 28-day cycle. Pharmacodynamic analyses included 5-methyl-2'-deoxycytidine levels, MAGE1A CpG island methylation, and fetal hemoglobin (HbF) expression. RESULTS The major toxicity was myelosuppression. Dose limiting toxicities, prolonged grade 4 neutropenia (one patient), and sepsis and grade 3 anorexia/fatigue (one patient), were seen in two of four patients treated with decitabine 135 mg/m2 and carboplatin AUC 5. Dose limiting toxicity comprising neutropenic sepsis (one patient) and grade 3 fatigue (one patient) was seen in two of 10 patients treated at decitabine 90 mg/m2 and carboplatin AUC 6. Decitabine induced dose-dependent, reversible demethylation in peripheral-blood cells (PBCs) maximally at day 10. Furthermore, decitabine 90 mg/m2 induced demethylation of the MAGE1A CpG island in PBCs, buccal cells, and tumor biopsies, as well as elevation of HbF expression. CONCLUSION Decitabine can be combined safely with carboplatin at a dose and schedule that causes epigenetic changes equivalent to or greater than that observed in mice with carboplatin-sensitized xenografts. The recommended dose/schedule for phase II trials is decitabine 90 mg/m2 (day 1) followed by carboplatin AUC 6 (day 8) every 28 days.

Abstract
Protein kinase C (PKC) comprises a family of serine/threonine kinases that are involved in the transduction of signals for cell proliferation, differentiation, apoptosis and angiogenesis. Unsurprisingly, disruption of PKC regulation is implicated in tumorigenesis and drug resistance. PKC function is complex in this context owing to the differing roles of individual isozymes within the cell and across tumour types. Therapeutically targeting PKC isozymes is not new; however, with many of the early PKC inhibitor cytotoxic drug combinations being discarded at the phase II level, and recent phase III studies in non-small-cell lung cancer proving negative, what's going wrong?

Abstract
OBJECTIVES This study evaluates the efficacy and toxicity of single-agent irinotecan following hepatectomy for metachronous colorectal metastases, and examines the predictive value of p27 and p53 expression and of microsatellite instability (MSI) status. METHODS Twenty-nine patients, previously treated with 5-fluorouracil, with operable hepatic colorectal metastases underwent hepatectomy and received adjuvant irinotecan (thrice weekly) for 6 planned cycles. Metastases were examined for p53 and p27 expression by immunohistochemistry and for MSI using mono- and dinucleotide markers. RESULTS The starting dose of irinotecan was 350 mg/m2 (in 3 patients), 300 mg/m2 (n = 14), and 250 mg/m2 (n = 12). Four patients failed to complete 6 cycles (2 progressive disease and 2 toxicity). Grade > or =3 toxicity was experienced in 8% of cycles (13 of 165). The estimated median relapse-free survival (RFS) was 45.2 months. RFS at 18 months was estimated to be 59% (95% confidence interval [CI], 43-80), 2-year overall survival (OS) was 85% (95% CI, 72-99.8), and the median follow-up was 27.9 months. Six patients (21%) have died; median OS has not been reached. In univariate analyses, p27 and MSI status were not predictive for RFS while p53 approached statistical significance (P = 0.051). Duration of chemotherapy was the only significant predictive factor (P = 0.006). CONCLUSION The tolerability of this regimen after major liver resection supports further evaluation of irinotecan-based adjuvant chemotherapy in this group of patients.

Abstract
PURPOSE BMS-214662 is a potent and selective inhibitor of the farnesyl transferase enzyme with in vitro and in vivo antitumor activity. The aims of this study were to characterize the toxicities and to determine the pharmacokinetic profiles of BMS-214662 when administered in combination with cisplatin, and to determine the constitutive farnesyltransferase activity as a surrogate pharmacodynamic end point. EXPERIMENTAL DESIGN Twenty-nine patients with advanced solid malignancy, refractory to conventional therapy, and with adequate hematological, renal, and hepatic function were treated with escalating doses of BMS-214662 administered as a 1-h infusion, followed after an interval of 30 min by 75 mg/m(2) cisplatin administered as a 4-h infusion and repeated every 21 days. Blood and urine samples for pharmacokinetic and pharmacodynamic analyses were collected during the first cycle of treatment only. RESULTS Dose-limiting toxicities occurred in 4 of 9 patients enrolled at the 225 mg/m(2) BMS-214662 dose cohort, and included elevation of hepatic transaminases, nausea, vomiting, diarrhea, and renal failure. There was no apparent pharmacokinetic interaction between the two drugs at the recommended dose levels, and a dose-dependent inhibition of farnesyltransferase activity was observed, which returned to control levels within 24 h of drug administration. There were no objective responses, but disease stabilization was observed in 15 patients, including 4 patients with stable disease after 6 cycles of treatment. CONCLUSIONS A dose of 200 mg/m(2) of BMS-214662 administered as a 1-h infusion with 75 mg/m(2) cisplatin over 4 h is the recommended dose for additional studies.

Abstract
Protein kinase C (PKC) is a family of serine/threonine kinases that is involved in the transduction of signals for cell proliferation and differentiation. The important role of PKC in processes relevant to neoplastic transformation, carcinogenesis and tumour cell invasion renders it a potentially suitable target for anticancer therapy. Furthermore, there is accumulating evidence that selective targeting of PKC may improve the therapeutic efficacy of established neoplastic agents and sensitise cells to ionising radiation. This article reviews the rationale for targeting PKC, focuses on its role in breast cancer and reviews the preclinical and clinical data available for the efficacy of PKC inhibition.

Abstract
BACKGROUND The aim of this study was to determine the maximum tolerated dose (MTD), toxicity profile and response rate of the oral 5-fluorouracil prodrug UFT (tegafur/uracil) and leucovorin (LV) in combination with irinotecan in patients with advanced or metastatic colorectal cancer. PATIENTS AND METHODS Patients with histologically proven advanced or metastatic colorectal adenocarcinoma received first-line chemotherapy comprising UFT 250 mg/m(2)/day and LV 90 mg/day given on days 1 to 14, with escalating doses of irinotecan (200-300 mg/m(2)) administered intravenously on day 1 of a three-weekly cycle. Eligibility criteria were standard. The MTD was defined as the dose at which >33% of six patients experienced a dose-limiting toxicity (DLT) during cycle 1. RESULTS A total of 32 patients were studied. Initially, six patients were treated at each of the irinotecan dose levels (200, 250 and 300 mg/m(2)) combined with UFT 250 mg/m(2)/day and LV 90 mg/day. DLTs consisting of grade 3 or 4 diarrhoea and febrile neutropenia were observed in one of 20 patients at 250 mg/m(2) and three of six patients at the 300 mg/m(2) irinotecan dose level. Having defined the MTD, the 250 mg/m(2) dose level was established as the recommended dose (RD) and expanded to 20 patients in whom treatment was generally well tolerated. The overall response rate was 19%, with five patients having a partial response (PR) and 18 stable disease (SD) out of 32 response-evaluable patients. CONCLUSION UFT and LV can be safely combined with irinotecan. The RDs for future studies are UFT 250 mg/m(2)/day and LV 90 mg/day given on days 1-14, with irinotecan 250 mg/m(2) administered on day 1, every 3 weeks. This combination is well tolerated and active. Further investigation of UFT and LV in combination with irinotecan is warranted in patients with colorectal cancer.

Abstract
AIM The aim of this study was to evaluate the activity of the combination of carboplatin and vinorelbine in patients with poor prognosis small cell lung cancer (SCLC). Patients with good prognosis disease were included who were not medically fit to tolerate conventional chemotherapy. Activity was assessed primarily as response rate and secondarily in terms of toxicity, time to progression and survival. PATIENTS AND METHODS Fifty-eight patients, 37 men and 21 women, with histologically or cytologically confirmed SCLC, who had bi-dimensionally measurable disease, with ECOG performance status > or = 2, with adequate haematological, hepatic and renal function received first-line chemotherapy with carboplatin (AUC x 5) day 1 and vinorelbine (30 mg/m2) days 1 and 8 of a 28-day cycle. Response was assessed after every two cycles of chemotherapy, with patients receiving a maximum of six cycles of treatment. RESULTS The combination of carboplatin and vinorelbine is an active regimen in the treatment of SCLC, with an overall intention-to-treat response rate of 55% [95% confidence interval (CI): 42-68%] with six (10%) of patients having a complete response. Median time to progression was 18 weeks (95% CI: 15-21 weeks). Median overall survival was 26 weeks (95% CI: 21-31 weeks). Ten patients failed to complete two cycles of treatment, and were not evaluable for response for the following reasons: septic death (1 neutropaenic, 1 no myelotoxicity), non-toxic death (1 tumour eroded through the pulmonary artery, 1 ischaemic heart disease) ischaemic heart disease (1) and patient decision (5). There were a total of three toxic deaths all sepsis-complicating neutropaenia. Forty-four (76%) patients experienced grade 3 or 4 neutropaenia, six (11%) grade 3 or 4 thrombocytopaenia, 10 (13%) grade 3 lethargy, three (5%) grade 3 nausea and two (3%) grade 3 diarrhoea. CONCLUSIONS The combination of carboplatin and vinorelbine is active against SCLC but the toxicity profile in this group of patients suggests that further evaluation is not appropriate.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of the combination of epirubicin, cisplatin and ralitrexed (Tomudex). ECT, in patients with advanced oesophageal or gastric adenocarcinoma. Efficacy was assessed primarily as response rate and secondarily in terms of toxicity, time to progression and survival. PATIENTS AND METHODS Twenty-one patients with histologically and/or cytologically proven unresectable (7) or metastatic (14) gastro-oesophageal adenocarcinoma, who had bi-dimensionally measurable disease, with ECOG performance status < or = 2. with adequate haematological, hepatic and renal function received first-line chemotherapy with epirubicin (50 mg/m2). cisplatin (60 mg/m2) and Tomudex (2.5 mg/m2), ECT, at three-weekly intervals. Treatment consisted of three cycles of chemotherapy, with a further three cycles if there was disease response or stabilisation. RESULTS ECT is an active regimen in the treatment of advanced gastro-oesophageal adenocarcinoma with an overall intention-to-treat response rate of 29% (95% confidence intervals (CI): 11%-52%). In addition, 4 (19%) patients had stable disease. Median time to progression was 19 weeks (95% CI: 7-31 weeks). Median overall survival was 18 weeks (95% CI: 11-24 weeks). Seventeen patients failed to complete the six cycles of treatment due to disease progression (5). toxicity (3), non-toxic death (1 pulmonary embolism, 1 cardiac), severe allergy to epirubicin (1), patient decision (1) and five patients after the study was discontinued early due to toxicity. There were three toxic deaths: two due to sepsis complicating neutropaenia and one due to cardiorespiratory failure following drug induced enteritis. Nine patients experienced grade 3 or 4 neutropaenia, two patients experienced grade 3 or 4 nausea and vomiting and one patient had grade 4 diarrhoea. CONCLUSIONS The combination of epirubicin, cisplatin and tomudex is active against advanced gastro-oesophageal adenocarcinoma but the toxicity suggests that further evaluation in a randomised comparison to ECF is not appropriate.

Abstract
PURPOSE Loss of function or expression of the mismatch repair protein MLH1 and the tumor suppressor protein p53 have been implicated in acquired resistance to anticancer drugs. We have compared the expression of MLH1 and p53 in tumors from women with clinically node-positive breast cancer before and after primary (neoadjuvant) chemotherapy. Further, we have assessed the value of these markers as predictors of response to therapy by correlation with disease-free survival. PATIENTS AND METHODS Immunohistochemistry scores of MLH1 and p53 expression were made on 36 tru-cut prechemotherapy biopsies and 29 paired postchemotherapy tumor samples. The significance of the change in scores and their correlation with disease-free survival were evaluated by the Wilcoxon signed rank sum test and Cox proportional hazards regression analysis, respectively. RESULTS Primary chemotherapy results in a significant reduction in the percent of cells expressing MLH1 (P =.010). This change in MLH1 expression after chemotherapy is strongly associated with poor disease-free survival (P =.0025). Expression of p53 was not significantly altered by chemotherapy. Neither MLH1 nor p53 expression before chemotherapy predicted disease-free survival or tumor response to chemotherapy. Low MLH1 expression after chemotherapy was an independent predictor of poor disease-free survival on multivariate Cox analysis when considered with other clinicopathologic prognostic factors. CONCLUSION Tumor cells that have reduced MLH1 expression seem to have a survival advantage during combined chemotherapy of locally advanced breast cancers, which supports the hypothesis that loss of MLH1 has a role in drug resistance. MLH1 expression after chemotherapy is an independent predictive factor for poor disease-free survival and may, therefore, define a group of patients with drug-resistant breast cancer.

Abstract
The purpose of this study was to evaluate the toxicity and activity of continuous infusional 5-fluorouracil (5-FU) given at three dose levels in combination with cyclophosphamide and doxorubicin (FAC) in women with breast cancer. Thirty-nine patients with either primary tumours >3 cm prior to surgery (n = 24) or metastatic disease (n = 15) received cyclophosphamide 600 mg/m2 and doxorubicin 50 mg/m2 as an intravenous bolus every 3 weeks for six courses. Continuous infusional 5-FU was delivered via a central venous line for a maximum of 18 weeks at dose levels of 100 mg/m2 per day (n = 6), 150 mg/m2 per day (n = 3) and 200 mg/m2 per day (n = 30). At the 200 mg/m2 per day dose level, 36% of patients required dose delays and 23% dose reductions; there was one death due to neutropenic sepsis. Hickman line complications occurred at all dose levels, particularly thrombosis (18%) and infection (33%). The response rate was 62% (95% confidence interval (CI) 32-84) for metastatic disease, including five complete responses (CRs). The response rate for primary tumours prior to surgery was 81% (95% CI 57-95) including six clinical CRs. Infusional FAC is an active regimen and has an acceptable toxicity profile. It does not, however, appear to offer any significant advantage over other chemotherapy regimens. This study does not support the further evaluation of infusional 5-FU at these doses in combination with doxorubicin and cyclophosphamide.

Abstract
We assessed the role of human CD52 antibody (Campath-1H) in six patients with chronic lymphocytic leukaemia (CLL) treated to maximal response with purine analogues (fludarabine/deoxycoformycin) in whom persistent leukaemic infiltration of blood and bone marrow had precluded autologous stem cell transplantation. Five patients achieved haematological and histological complete remission following Campath-1H and one had minimal focal residual CLL in a trephine biopsy. Autologous transplantation was performed in two patients without complications and with rapid haemopoietic engraftment. Treatment with Campath-1H may be of value in eradicating residual disease in CLL and may facilitate high-dose therapy in young patients.
