Abstract
There were high hopes for the new antiangiogenic medicament, bevacizumab, which could inhibit the creation of new blood vessels through binding to isoform A of vascular endothelial growth factor (VEGF). However, it is not only blood vessels that are responsible for tumor cell spread. During the process of tumor growth, lymphangiogenesis is mediated by other members of the VEGF family, specifically VEGF-C and VEGF-D, which act independent to bevacizumab. Therefore, based on the mechanism of bevacizumab action and the processes of angio- and lymphangiogenesis, we formed three hypotheses: (1) if the lymph nodes in primary ovarian cancers are metastatic, the outcome of bevacizumab treatment is worsened; (2) concerning the second-line treatment, bevacizumab will act in a weakened manner if recurrence occurs in lymph nodes as opposed to a local recurrence; (3) patients treated by bevacizumab are more likely to have recurrences in lymph nodes. These hypotheses raise the issue of the existing knowledge gap, which concerns the effect of bevacizumab on metastatic lymph nodes.

Abstract
Cervical cancer patients with distant or loco-regional recurrences not amenable by surgery or radiotherapy have limited treatment options, and their 5-year overall survival (OS) rates range from 5% to 16%. The purpose of this paper is to assess the results obtained with chemotherapy and biological agents in this clinical setting. Several phase II trials of different cisplatin (CDDP)-based doublets and a phase III randomized trial showing a trend in response rate, progression-free survival, and OS in favor of CDDP + paclitaxel (PTX) compared with other CDDP-based doublets have been reviewed. The factors predictive of response to chemotherapy as well as the benefits and risks of the addition of bevacizumab to CDDP + PTX have been analyzed. The FDA has recently approved pembrolizumab for patients with recurrent or metastatic cervical cancer in progression on or after chemotherapy whose tumors were PD-L1 positive. Interesting perspectives of clinical research are represented by the use of immune checkpoint inhibitors alone or in addition to chemotherapy, whereas PARP inhibitors and PI3K inhibitors are still at the basic research phase, but promising.

Abstract
Microbes are nature's chemists, capable of producing and metabolizing a diverse array of compounds. In the human gut, microbial biochemistry can be beneficial, for example vitamin production and complex carbohydrate breakdown; or detrimental, such as the reactivation of an inactive drug metabolite leading to patient toxicity. Identifying clinically relevant microbiome metabolism requires linking microbial biochemistry and ecology with patient outcomes. Here we present MicrobeFDT, a resource which clusters chemically similar drug and food compounds and links these compounds to microbial enzymes and known toxicities. We demonstrate that compound structural similarity can serve as a proxy for toxicity, enzyme sharing, and coarse-grained functional similarity. MicrobeFDT allows users to flexibly interrogate microbial metabolism, compounds of interest, and toxicity profiles to generate novel hypotheses of microbe-diet-drug-phenotype interactions that influence patient outcomes. We validate one such hypothesis experimentally, using MicrobeFDT to reveal unrecognized gut microbiome metabolism of the ovarian cancer drug altretamine.

Abstract
PURPOSE KEYNOTE-158 ( ClinicalTrials.gov identifier: NCT02628067) is a phase II basket study investigating the antitumor activity and safety of pembrolizumab in multiple cancer types. We present interim results from patients with previously treated advanced cervical cancer. PATIENTS AND METHODS Patients received pembrolizumab 200 mg every 3 weeks for 2 years or until progression, intolerable toxicity, or physician or patient decision. Tumor imaging was performed every 9 weeks for the first 12 months and every 12 weeks thereafter. The primary end point was objective response rate (ORR), assessed per Response Evaluation Criteria in Solid Tumors (version 1.1) by independent central radiologic review. Safety was a secondary end point. RESULTS Ninety-eight patients were treated. Median age was 46.0 years (range, 24 to 75 years), and 65.3% of patients had Eastern Cooperative Oncology Group performance status of 1. Eighty-two patients (83.7%) had programmed death-ligand 1 (PD-L1)-positive tumors (combined positive score ≥ 1), 77 having previously received one or more lines of chemotherapy for recurrent or metastatic disease. Median follow-up was 10.2 months (range, 0.6 to 22.7 months). ORR was 12.2% (95% CI, 6.5% to 20.4%), with three complete and nine partial responses. All 12 responses were in patients with PD-L1-positive tumors, for an ORR of 14.6% (95% CI, 7.8% to 24.2%); 14.3% (95% CI, 7.4% to 24.1%) of these responses were in those who had received one or more lines of chemotherapy for recurrent or metastatic disease. Median duration of response was not reached (range, ≥ 3.7 to ≥ 18.6 months). Treatment-related adverse events occurred in 65.3% of patients, and the most common were hypothyroidism (10.2%), decreased appetite (9.2%), and fatigue (9.2%). Treatment-related grade 3 to 4 adverse events occurred in 12.2% of patients. CONCLUSION Pembrolizumab monotherapy demonstrated durable antitumor activity and manageable safety in patients with advanced cervical cancer. On the basis of these results, the US Food and Drug Administration granted accelerated approval of pembrolizumab for patients with advanced PD-L1-positive cervical cancer who experienced progression during or after chemotherapy.

Abstract
For patients with primary stage ⅣB, persistent, or recurrent cervical cancer, chemotherapy remains the standard treatment, although it is neither curative nor associated with long-term disease control. In this review, we summarized the history of treatment of recurrent cervical cancer, and the current recommendation for chemotherapy and molecular targeted therapy. Eligible articles were identified by a search of the MEDLINE bibliographical database for the period up to November 30, 2014. The search strategy included the following any or all of the keywords: “uterine cervical cancer”, “chemotherapy”, and “targeted therapies”. Since cisplatin every 21 days was considered as the historical standard treatment for recurrent cervical cancer, subsequent trials have evaluated and demonstrated activity for other agents including paclitaxel, gemcitabine, topotecan and vinorelbine among others. Accordingly, promising agents were incorporated into phase Ⅲ trials. To examine the best agent to combine with cisplatin, several landmark phase Ⅲ clinical trials were conducted by Gynecologic Oncology Group (GOG) and Japan Clinical Oncology Group (JCOG). Through, GOG204 and JCOG0505, paclitaxel/cisplatin (TP) and paclitaxel/carboplatin (TC) are now considered to be the recommended therapies for recurrent cervical cancer patients. However, the prognosis of patients who are already resistant to chemotherapy, are very poor. Therefore new therapeutic strategies are urgently required. Molecular targeted therapy will be the most hopeful candidate of these strategies. From the results of GOG240, bevacizumab combined with TP reached its primary endpoint of improving overall survival (OS). Although, the prognosis for recurrent cervical cancer patients is still poor, the results of GOG240 shed light on the usefulness of molecular target agents to chemotherapy in cancer patients. Recurrent cervical cancer is generally considered incurable and current chemotherapy regiments offer only modest gains in OS, particularly for patients with multiple poor prognostic factors. Therefore, it is crucial to consider not only the survival benefit, but also the minimization of treatment toxicity, and maximization of quality of life (QOL).

Abstract
A feasibility study was performed to evaluate the immunological efficacy and safety of a personalized peptide vaccine (PPV) for cervical cancer patients who have received platinum-based chemotherapy. A total of 24 patients with standard chemotherapy-resistant cervical cancer, including 18 recurrent cases, were enrolled in this study and received a maximum of 4 peptides based on HLA-A types and IgG levels to the vaccine candidate peptides in pre-vaccination plasma. The parental protein expression of most of the vaccine peptides was confirmed in the cervical cancer tissues. No vaccine-related systemic grade 3 or 4 adverse events were observed in any patients. Due to disease progression, 2 patients failed to complete the first cycle of vaccinations (sixth vaccination). Cytotoxic T-lymphocyte (CTL) or IgG responses specific for the peptides used for vaccination were augmented in half of cases after the first cycle. The median overall survival was 8.3 months. The clinical responses of the evaluable 18 cases consisted of 1 case with a partial response and 17 cases with disease progression; the remaining 6 cases were not evaluable. Performance status, injection site skin reaction and circulating PD-1+CD4+ T-cells were significantly prognostic of overall survival, and multivariate analysis also indicated that the performance status and circulating PD-1+CD4+ T-cells were prognostic. Because of the safety and immunological efficacy of PPV and the possible prolongation of overall survival, further clinical trials of PPV at a larger scale in advanced or recurrent cervical cancer patients who have received prior platinum-based chemotherapy are recommended.

Abstract
BACKGROUND Metastatic and recurrent, platinum resistant cervix cancer has an extremely poor prognosis. The Gynecologic Oncology Group has studied >20 cytotoxic drugs or drug combinations in the second-line, phase II setting of advanced, drug resistant cervix cancer. METHODS Nanoparticle, albumin-bound paclitaxel (nab-paclitaxel) was administered at 125 mg/m(2) IV over 30 minutes on days 1, 8 and 15 of each 28 day cycle to 37 women with metastatic or recurrent cervix cancer that had progressed or relapsed following first-line cytotoxic drug treatment. A flexible, 2-stage accrual design that allowed stopping early for lack of treatment activity was utilized. Because of slow patient accrual, the second stage was not completed. RESULTS Of 37 patients enrolled, 2 were ineligible due to no prior cytotoxic chemotherapy, which left 35 eligible patients evaluable for response and tolerability. All of the eligible patients had 1 prior chemotherapy regimen and 27 of them had prior radiation therapy with concomitant cisplatin. The median number of nab-paclitaxel cycles were 4 (range 1-15). Ten (28.6%; CI 14.6%-46.3%) of the 35 patients had a partial response and another 15 patients (42.9%) had stable disease. The median progression-free and overall survival were 5.0 and 9.4 months, respectively. The only NCI CTCAE grade 4 event was neutropenia in 2 patients (5.7%) which resolved following dose reduction. Grade 3 neurotoxicity was reported in 1 (2.9%) patient and resolved to grade 2 following dose discontinuation. CONCLUSIONS Nab-paclitaxel has considerable activity and moderate toxicity in the treatment of drug resistant, metastatic and recurrent cervix cancer.

Abstract
OBJECTIVES To determine the proportion of patients with tumor response, the proportion who survived progression-free for at least 6 months (progression-free survival >or= 6 months), and the frequency and severity of toxicities of patients with recurrent squamous cell carcinoma of the uterine cervix treated with erlotinib. METHODS This was a multicenter, open-label, single-arm trial evaluating the toxicity and efficacy of oral erlotinib at an initial dosage of 150 mg daily until progressive disease or adverse effects prohibited further therapy. RESULTS Twenty-eight patients with squamous cell carcinoma were enrolled onto this trial. Twenty-five patients were evaluable. There were no objective responses, with 4 (16%) patients achieving stable disease; only 1 patient had a progression-free survival of 6 months (4%) or more. The 1-sided 90% confidence interval for response was 0.0% to 8.8%. The 2-sided 90% confidence interval for the proportion of patients surviving progression-free for at least 6 months is 0.2% to 17.6%. Erlotinib was well tolerated, with the most common drug-related adverse events being gastrointestinal toxicities, fatigue, and rash. CONCLUSIONS Erlotinib is inactive as monotherapy in patients with recurrent squamous cell carcinoma of the uterine cervix.

Abstract
PURPOSE Vascular endothelial growth factor is a key promoter of tumor progression in cervical carcinoma. The Gynecologic Oncology Group (GOG) conducted a phase II trial to assess the efficacy and tolerability of bevacizumab, a recombinant humanized anti-vascular endothelial growth factor monoclonal antibody. PATIENTS AND METHODS Eligible patients had recurrent cervical cancer, measurable disease, and GOG performance status < or = 2. Treatment consisted of bevacizumab 15 mg/kg intravenously every 21 days until disease progression or prohibitive toxicity. Primary end points were progression-free survival (PFS) at 6 months and toxicity. RESULTS Forty-six patients were enrolled (median age, 46 years); 38 patients (82.6%) received prior radiation as well as either one (n = 34, 73.9%) or two (n = 12, 26.1%) prior cytotoxic regimens for recurrent disease. Grade 3 or 4 adverse events at least possibly related to bevacizumab included hypertension (n = 7), thrombo-embolism (n = 5), GI (n = 4), anemia (n = 2), other cardiovascular (n = 2), vaginal bleeding (n = 1), neutropenia (n = 1), and fistula (n = 1). One grade 5 infection was observed. Eleven patients (23.9%; two-sided 90% CI, 14% to 37%) survived progression free for at least 6 months, and five patients (10.9%; two-sided 90% CI, 4% to 22%) had partial responses. The median response duration was 6.21 months (range, 2.83 to 8.28 months). The median PFS and overall survival times were 3.40 months (95% CI, 2.53 to 4.53 months) and 7.29 months (95% CI, 6.11 to 10.41 months), respectively. This compared favorably with historical phase II GOG trials in this setting. CONCLUSION Bevacizumab seems to be well tolerated and active in the second- and third-line treatment of patients with recurrent cervical cancer and merits phase III investigation.

Abstract
OBJECTIVE To estimate the anti-tumor activity of pemetrexed in patients with advanced or recurrent carcinoma of the cervix that failed on higher priority treatment protocols and to determine the nature and degree of toxicity. METHODS A multicenter Phase II trial was conducted by the Gynecologic Oncology Group (GOG). Patients must have had advanced or recurrent measurable carcinoma of the cervix, and failed one prior chemotherapy regimen. Pemetrexed at a dose of 900 mg/m(2) was to be administered as an IV infusion over 10 min every 21 days. RESULTS From July 6, 2004 to April 3, 2006, twenty-nine patients were entered by ten member institutions of the GOG. Two patients did not receive treatment and thus were inevaluable. A total of 128 cycles were administered with 37% of patients receiving six or more cycles. The treatment was well tolerated overall. More serious toxicities (grade 3 and 4) included anemia in 41%, leukopenia in 30%, neutropenia in 26%, and infection in 26%. No treatment related deaths were reported. Four patients (15%) had partial responses with a median response duration of 4.4 months. The response rate for non-radiated or radiated disease sites was 25% and 7% respectively. Sixteen patients (59%) had stable disease and seven (26%) patients had increasing disease. Median progression free survival (PFS) was 3.1 months and overall survival (OS) was 7.4 months. CONCLUSION Pemetrexed at this dose and schedule showed moderate activity against advanced or recurrent cervical cancer that has failed prior chemotherapy. Data from other tumor sites has suggested synergy between pemetrexed and cisplatin and should be considered for further study.

Abstract
Because only 16% of patients with metastatic cervical cancer are alive 5 years after diagnosis, the Gynecologic Oncology Group (GOG) has carefully designed and conducted many phase II studies to identify promising drugs. Cisplatin has emerged as the most active single agent with overall response rates of 19%. Recent phase III trials have documented response rates of 27% and 39% when cisplatin has been combined with either paclitaxel or topotecan, respectively. The comparison of cisplatin to cisplatin plus topotecan in GOG-179 has yielded the first study to show a statistically significant impact on the overall response rate, median progression-free survival, and median survival, with all outcome measures favoring the two-drug regimen. Despite these encouraging results, however, most of the responses are partial and of short duration. The need for novel combinations and the implementation of active biologic agents is implicit. The accumulated data in this disease setting, as evidenced by the experience of the GOG, are presented in this review.
