The East Africa Consortium for human papillomavirus and cervical cancer in women living with HIV/AIDS.

The East Africa Consortium was formed to study the epidemiology of human papillomavirus (HPV) infections and cervical cancer and the influence of human immunodeficiency virus (HIV) infection on HPV and cervical cancer, and to encourage collaborations between researchers in North America and East African countries. To date, studies have led to a better understanding of the influence of HIV infection on the detection and persistence of oncogenic HPV, the effects of dietary aflatoxin on the persistence of HPV, the benefits of antiretroviral therapy on HPV persistence, and the differences in HPV detections among HIV-infected and HIV-uninfected women undergoing treatment for cervical dysplasia by either cryotherapy or LEEP. It will now be determined how HPV testing fits into cervical cancer screening programs in Kenya and Uganda, how aflatoxin influences immunological control of HIV, how HPV alters certain genes involved in the growth of tumours in HIV-infected women. Although there have been challenges in performing this research, with time, this work should help to reduce the burden of cervical cancer and other cancers related to HIV infection in people living in sub-Saharan Africa, as well as optimized processes to better facilitate research as well as patient autonomy and safety.

A cross-sectional analysis of factors associated with detection of oncogenic human papillomavirus in human immunodeficiency virus-infected and uninfected Kenyan women.

BACKGROUND: Cervical cancer is caused by oncogenic human papillomaviruses (HPV) and is one of the most common malignancies in women living in sub-Saharan Africa. Women infected with the human immunodeficiency virus (HIV) have a higher incidence of cervical cancer, but the full impact on HPV detection is not well understood, and associations of biological and behavioral factors with oncogenic HPV detection have not been fully examined. Therefore, a study was initiated to investigate factors that are associated with oncogenic HPV detection in Kenyan women. METHODS: Women without cervical dysplasia were enrolled in a longitudinal study. Data from enrollment are presented as a cross-sectional analysis. Demographic and behavioral data was collected, and HPV typing was performed on cervical swabs. HIV-uninfected women (n = 105) and HIV-infected women (n = 115) were compared for demographic and behavioral characteristics using t-tests, Chi-square tests, Wilcoxon sum rank tests or Fisher's exact tests, and for HPV detection using logistic regression or negative binomial models adjusted for demographic and behavioral characteristics using SAS 9.4 software. RESULTS: Compared to HIV-uninfected women, HIV-infected women were older, had more lifetime sexual partners, were less likely to be married, were more likely to regularly use condoms, and were more likely to have detection of HPV 16, other oncogenic HPV types, and multiple oncogenic types. In addition to HIV, more lifetime sexual partners was associated with a higher number of oncogenic HPV types (aIRR 1.007, 95% CI 1.007-1.012). Greater travel distance to the clinic was associated with increased HPV detection (aOR for detection of ≥ 2 HPV types: 3.212, 95% CI 1.206-8.552). Older age (aOR for HPV 16 detection: 0.871, 95% CI 0.764-0.993) and more lifetime pregnancies (aOR for detection of oncogenic HPV types: 0.706, 95% CI, 0.565-0.883) were associated with reduced detection. CONCLUSION: HIV infection, more lifetime sexual partners, and greater distance to health-care were associated with a higher risk of oncogenic HPV detection, in spite of ART use in those who were HIV-infected. Counseling of women about sexual practices, improved access to health-care facilities, and vaccination against HPV are all potentially important in reducing oncogenic HPV infections.

The Kenya cancer research and control stakeholder program: Evaluating a bilateral partnership to strengthen national cancer efforts.

Background: In response to a growing cancer burden and need for improved coordination among stakeholders in Kenya, the US National Cancer Institute and the Kenya Ministry of Health collaboratively hosted a stakeholder meeting in 2014 which identified four priority areas of need (research capacity building, pathology and cancer registries, cancer awareness and education, and health system strengthening) and developed corresponding action plans. Methods: Surveys were conducted with participants to collect input on the progress and impact of the 2014 stakeholder meeting. Findings: Of 69 eligible participants, 45 responded from academia, healthcare institutions, civil society, government, and international agencies. Of the four technical focus areas, three have continued to conduct working group meetings and two have conducted in-person meetings to review and update their respective action plans. Accomplishments linked to or enhanced by t meeting include: Kenyan and international support for expansion of population-based cancer registries, increased availability of prioritized diagnostic tests in selected regional referral hospitals, a greater focus on development of a national cancer research agenda, strategic planning for a community education strategy for cancer awareness, and improved coordination of partners through in-country technical assistance. Interpretation: The Stakeholder Program has successfully united individuals and organizations to improve cancer control planning in Kenya, and has enhanced existing efforts and programs across the country. This model of partners working in parallel on prioritized track activities has supported development of long term coordination of cancer research and control activities sustainable by the Kenyan government and Kenyan institutions.

Presynaptic dopaminergic terminal imaging and non-motor symptoms assessment of Parkinson's disease: evidence for dopaminergic basis?

Parkinson's disease (PD) is now considered to be a multisystemic disorder consequent on multineuropeptide dysfunction including dopaminergic, serotonergic, cholinergic, and noradrenergic systems. This multipeptide dysfunction leads to expression of a range of non-motor symptoms now known to be integral to the concept of PD and preceding the diagnosis of motor PD. Some non-motor symptoms in PD may have a dopaminergic basis and in this review, we investigate the evidence for this based on imaging techniques using dopamine-based radioligands. To discuss non-motor symptoms we follow the classification as outlined by the validated PD non-motor symptoms scale.

Building cancer nursing skills in a resource-constrained government hospital.

Cancer is a rising cause of morbidity and mortality in resource-constrained settings. Few places in the developing world have cancer care experts and infrastructure for caring for cancer patients; therefore, it is imperative to develop this infrastructure and expertise. A critical component of cancer care, rarely addressed in the published literature, is cancer nursing. This report describes an effort to develop cancer nursing subspecialty knowledge and skills in support of a growing resource-constrained comprehensive cancer care program in Western Kenya. This report highlights the context of cancer care delivery in a resource-constrained setting, and describes one targeted intervention to further develop the skill set and knowledge of cancer care providers, as part of collaboration between developed world academic institutions and a medical school and governmental hospital in Western Kenya. Based on observations of current practice, practice setting, and resource limitations, a pragmatic curriculum for cancer care nursing was developed and implemented.

HOXB13 is downregulated in colorectal cancer to confer TCF4-mediated transactivation.

Mutations in the Wnt signalling cascade are believed to cause aberrant proliferation of colorectal cells through T-cell factor-4 (TCF4) and its downstream growth-modulating factors. HOXB13 is exclusively expressed in prostate and colorectum. In prostate cancers, HOXB13 negatively regulates beta-catenin/TCF4-mediated transactivation and subsequently inhibits cell growth. To study the role of HOXB13 in colorectal tumorigenesis, we evaluated the expression of HOXB13 in 53 colorectal tumours originated from the distal left colon to rectum with their matching normal tissues using quantitative RT-PCR analysis. Expression of HOXB13 is either lost or diminished in 26 out of 42 valid tumours (62%), while expression of TCF4 RNA is not correlated with HOXB13 expression. TCF4 promoter analysis showed that HOXB13 does not regulate TCF4 at the transcriptional level. However, HOXB13 downregulated the expression of TCF4 and its target gene, c-myc, at the protein level and consequently inhibited beta-catenin/TCF-mediated signalling. Functionally, forced expression of HOXB13 drove colorectal cancer (CRC) cells into growth suppression. This is the first description of the downregulation of HOXB13 in CRC and its mechanism of action is mediated through the regulation of TCF4 protein stability. Our results suggest that loss of HOXB13 may be an important event for colorectal cell transformation, considering that over 90% of colorectal tumours retain mutations in the APC/beta-catenin pathway.

Do benefits and barriers differ by stage of adoption for colorectal cancer screening?

In 2003, over 148,300 people were expected to be diagnosed and 56,000 to die from colorectal cancer (CRC). First-degree relatives (FDRs) of people with colon cancer have a two- to eight-fold increased risk for CRC. Despite evidence that screening is effective, adherence with screening recommendations in this at-risk population is low. This study's purposes were to (1) identify perceived benefits and barriers of fecal occult blood testing (FOBT), sigmoidoscopy and colonoscopy, and (2) compare demographic characteristics and perceived benefits and barriers by stage of adoption for CRC screening. Participating FDRs (n = 257) completed a 40-min structured telephone interview. Despite high rates of agreement with the benefits of screening, most FDRs were not contemplating being screened. Of those 50 and older, most were in precontemplation for FOBT, sigmoidoscopy and colonoscopy. Older age was related to stage for FOBT and sigmoidoscopy, but not colonoscopy. Lack of provider recommendation also was related to stage. Consistent with theoretical predictions, precontemplators had (1) higher rates of endorsement of specific barriers to screening and (2) lower rates of endorsement of benefits than contemplators or actors. For morbidity and mortality reduction, participation in routine, periodic screening is imperative. These findings can guide development of screening-promoting interventions.

Comparison of the efficacy, toxicity, and pharmacokinetics of a uracil/tegafur (UFT) plus oral leucovorin (LV) regimen between Japanese and American patients with advanced colorectal cancer: joint United States and Japan study of UFT/LV.

PURPOSE: To compare the efficacy, toxicities, and pharmacokinetics of an oral regimen consisting of uracil/tegafur (UFT) and leucovorin (LV) between Japanese patients and patients in the United States with previously untreated metastatic colorectal cancer. PATIENTS AND METHODS: Forty-four Japanese patients and 45 patients in the United States were enrolled in concurrent nonrandomized phase II trials. UFT 300 mg/m2/d and leucovorin 75 mg/d were administered orally for 28 days followed by a 7-day rest period. The total daily dose of each drug was divided into three equal doses. Treatment was repeated every 5 weeks until disease progression. Blood samples for the pharmacokinetic study were obtained after the initial dose on day 1 of the first course. RESULTS: The response rate for the Japanese patients and the patients in the United States was 36.4% (95% CI, 22.4% to 52.2%) and 34.1% (95% CI, 20.5% to 49.9%), respectively. The only major toxicity was diarrhea, and other toxicities were mild in both populations. The incidence of grade 3 or higher diarrhea in the Japanese and Americans was 9% and 22%, respectively. Although the area under the curve and maximum concentration of fluorouracil were found to be slightly higher in the Japanese patients than the patients in the United States, and area under the curve-adjusted body surface area appeared to be comparable between the two groups. CONCLUSION: The efficacy and pharmacokinetic parameters of UFT and LV are comparable in Japanese and American patients; however, a difference in toxicity profile, specifically diarrhea, was noted. This oral regimen of UFT and LV is considered to have similar activity against metastatic colorectal cancer and to have acceptable toxicity in patients in both countries.

Absence of human T-cell lymphotropic virus type I and human foamy virus in thymoma.

The cause of thymoma, a rare malignancy of thymic epithelial cells, is unknown. Recent studies have reported the detection of DNA from human T-cell lymphotropic virus type I (HTLV-I) and human foamy virus (HFV) in small numbers of thymoma tumours, suggesting an aetiologic role for these retroviruses. In the present study, we evaluated 21 US thymoma patients and 20 patients with other cancers for evidence of infection with these viruses. We used the polymerase chain reaction to attempt to amplify viral DNA from tumour tissues, using primers from the pol and tax (HTLV-I) and gag and bel1 (HFV) regions. In these experiments, we did not detect HTLV-I or HFV DNA sequences in any thymoma or control tissues, despite adequate sensitivity of our assays (one HTLV-I copy per 25 000 cells, one HFV copy per 7500 cells). Additionally, none of 14 thymoma patients evaluated serologically for HTLV I/II infection was positive by enzyme-linked immunoassay (ELISA), while five (36%) had indeterminate Western blot reactivity. In comparison, one of 20 US blood donors was HTLV-I/II ELISA positive, and nine (45%) donors, including the ELISA-positive donor, had indeterminate Western blot reactivity. Western blot patterns varied across individuals and consisted mostly of weak reactivity. In conclusion, we did not find evidence for the presence of HTLV-I or HFV in US thymoma patients.

Epidermal growth factor receptor expression in invasive thymoma.

PURPOSE: Epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein with intrinsic tyrosine kinase activity. Activation results in a variety of cellular responses including cell proliferation and differentiation. In clinical trials, anti-EGFR is showing promise in the treatment of solid tumors expressing EGFR. Thus, we assessed EGFR expression in a series of thymic epithelial tumors. METHODS: Tumors from 37 patients seen at Indiana University School of Medicine (IUMC) for treatment of thymoma (31 patients) or thymic carcinoma (six patients) were assessed for EGFR expression. Five-micron sections of formalin-fixed, paraffin-embedded tumor (28 invasive and/or metastatic thymomas, six thymic carcinomas, and three non-invasive thymomas) were stained with anti-EGFR. Any degree of cytoplasmic membrane staining of tumor cells was considered positive; furthermore, staining was scored 0 to 3+ using criteria as standardized for HER-2/neu assessment of breast carcinoma. Appropriate controls were performed. RESULTS: Positive staining of tumor was observed in 28 tumors (23 invasive and/or metastatic thymomas, two thymic carcinomas, and three non-invasive thymomas). CONCLUSIONS: EGFR is expressed in a high percentage of thymic epithelial tumors. EGFR is often strongly expressed and is a potential therapeutic target in patients with malignant thymic tumors. We are pursuing additional studies to assess anti-EGRF in the treatment of patients with advanced thymoma.

Maintenance daily oral etoposide versus no further therapy following induction chemotherapy with etoposide plus ifosfamide plus cisplatin in extensive small-cell lung cancer: a Hoosier Oncology Group randomized study.

BACKGROUND: We performed this phase III study to determine whether the addition of 3 months of oral etoposide in non-progressing patients with extensive small-cell lung cancer (SCLC) treated with four cycles of etoposide plus ifosfamide plus cisplatin (VIP) improves progression-free survival (PFS) or overall survival. PATIENTS AND METHODS: Patients with extensive SCLC with a Karnofsky performance score (KPS) > or =50, adequate renal function and bone marrow reserve were eligible. Patients with CNS metastasis were eligible and received concurrent whole-brain radiotherapy. All patients received etoposide 75 mg/m2, ifosfamide 1.2 g/m2 and cisplatin 20 mg/m2 intravenously on days 1-4 every 3 weeks for four cycles. Non-progressing patients were randomized to oral etoposide 50 mg/m2 for 21 consecutive days every 4 weeks for three courses versus no further therapy until progression. RESULTS: From September 1993 to June 1998, 233 patients were entered and treated with VIP with 144 non-progressing patients subsequently randomized to oral etoposide (n = 72) or observation (n = 72). Minimum follow up for all patients is 2 years. Toxicity with oral etoposide was mild. There was an improvement in median PFS favoring the maintenance arm of 8.23 versus 6.5 months (P = 0.0018). There was a trend towards an improvement in median (12.2 versus 11.2 months), 1-year (51.4% versus 40.3%), 2-year (16.7% versus 6.9%) and 3-year (9.1% versus 1.9%) survival (P = 0.0704) favoring the maintenance arm. CONCLUSIONS: Three months of oral etoposide in non-progressing patients with extensive SCLC was associated with a significant improvement in PFS and a trend towards improved overall survival.

High-dose carboplatin with etoposide in patients with recurrent thymoma: the Indiana University experience.

Thymoma is a chemotherapy-sensitive tumor with a 30-50% 5-year survival in previously untreated patients. Unfortunately, durable CRs with salvage chemotherapy are rarely observed. We initiated a phase II trial of high-dose carboplatin and etoposide in patients with relapsed thymoma or thymic carcinoma. All patients had progressive disease (PD) after initial or salvage chemotherapy, but were not cisplatin-refractory. PBSCs were mobilized using 10 microg/kg/day G-CSF. Patients received carboplatin 700 mg/m(2) and etoposide 750 mg/m(2) i.v. on days -5, -4, -3. Five patients were enrolled and evaluated after tandem transplants 4 weeks apart. All patients had pleural-based and lung parenchymal metastasis, one or two prior surgeries and two or more courses of prior cisplatin-based chemotherapy regimens. Chemotherapy was well tolerated, although grade IV hematological toxicity occurred in all patients. Progression-free survival following HDC ranged from 3.5 to 16.5 months. One patient maintained a CR for 12.8 months, then died from an unrelated cause. With a minimum of 2 years follow-up for all patients, three of five patients remain alive at 26+, 36+, and 49+ months. High-dose carboplatin and etoposide in relapsed thymoma is feasible with acceptable toxicity; however, these limited data do not appear superior to standard-dose salvage therapy.

Altretamine for the treatment of metastatic renal cell carcinoma. A Hoosier Oncology Group trial.

Thirty patients with advanced renal cell carcinoma were treated on a phase 11 trial with altretamine. Altretamine was administered orally at a dosage of 260 mg/m2 days 1 through 14 with cycles repeated every 28 days. Nausea and vomiting were the most common toxicities. Ten percent (3 of 30) experienced Grade 3 gait abnormalities. None of the thirty evaluable patients achieved a complete or partial response. In summary, altretamine did not show antitumor activity in the treatment of advanced renal cell carcinoma.

Combined etoposide, ifosfamide, and cisplatin in the treatment of patients with advanced thymoma and thymic carcinoma: an intergroup trial.

BACKGROUND: Patients with thymic tumors (thymoma and thymic carcinoma) are known to respond to a variety of chemotherapeutic agents, including single-agent ifosfamide and cisplatin with etoposide. The purpose of this trial was to evaluate the response rate, progression free survival, overall survival, and toxicity of combined etoposide, ifosfamide, and cisplatin (VIP) in patients with advanced thymoma and thymic carcinoma. METHODS: From July 1995 through February 1997, 34 patients with advanced thymoma or thymic carcinoma were entered on trial to receive etoposide (75 mg/m2 on Days 1-4) ifosfamide (1.2 g/m2 on Days 1-4), and cisplatin (20 mg/m2 on Days 1-4). Cycles were repeated every 3 weeks for four total cycles. RESULTS: Among 28 evaluable patients (pathology review excluded 6 patients), there were no complete responses and 9 partial responses (complete and partial responses combined, 32%; 95% confidence interval, 16-52%). The median follow-up was 43 months (range, 12.8-52.3 months), the median duration of response was 11.9 months (range, < 1-26 months), and the median overall survival was 31.6 months. Based on Kaplan-Meier estimates, the 1-year and 2-year survival rates were 89% and 70%, respectively. The toxicity was predominantly myelosuppression. CONCLUSIONS: The VIP regimen has moderate activity in patients with advanced thymic malignancies. However, with limited follow-up, the results of this trial appear to be inferior to other chemotherapy regimens reported in large Phase II trials performed in patients with this disease.

Thymic malignancies.

Thymomas and thymic carcinomas are unique tumors of the anterior mediastinum. The association of a variety of different paraneoplastic syndromes with such lesions has fascinated physicians and researchers for years. Most recently, it has been demonstrated by numerous authors that thymomas are chemosensitive tumors. Their indolent nature and relative rarity have made evaluation through prospective randomized clinical trials extremely difficult. Further information regarding the molecular nature of these neoplasms and immunologic aspects is needed in future investigation.

Phase III trial of interferon alfa-2a with or without 13-cis-retinoic acid for patients with advanced renal cell carcinoma.

PURPOSE: A randomized phase III trial was conducted to determine whether combination therapy with 13-cis-retinoic acid (13-CRA) plus interferon alfa-2a (IFNalpha2a) is superior to IFNalpha2a alone in patients with advanced renal cell carcinoma (RCC). PATIENTS AND METHODS: Two hundred eighty-four patients were randomized to treatment with IFNalpha2a plus 13-CRA or treatment with IFNalpha2a alone. IFNalpha2a was given daily subcutaneously, starting at a dose of 3 million units (MU). The dose was escalated every 7 days from 3 to 9 MU (by increments of 3 MU), unless >/= grade 2 toxicity occurred, in which case dose escalation was stopped. Patients randomized to combination therapy were given oral 13-CRA 1 mg/kg/d plus IFNalpha2a. Quality of life (QOL) was assessed. RESULTS: Complete or partial responses were achieved by 12% of patients treated with IFNalpha2a plus 13-CRA and 6% of patients treated with IFNalpha2a (P =.14). Median duration of response (complete and partial combined) in the group treated with the combination was 33 months (range, 9 to 50 months), versus 22 months (range, 5 to 38 months) for the second group (P =.03). Nineteen percent of patients treated with IFNalpha2a plus 13-CRA were progression-free at 24 months, compared with 10% of patients treated with IFNalpha2a alone (P =.05). Median survival time for all patients was 15 months, with no difference in survival between the two treatment arms (P =.26). QOL decreased during the first 8 weeks of treatment, and a partial recovery followed. Lower scores were associated with the combination therapy. CONCLUSION: Response proportion and survival did not improve significantly with the addition of 13-CRA to IFNalpha2a therapy in patients with advanced RCC. 13-CRA may lengthen response to IFNalpha2a therapy in patients with IFNalpha2a-sensitive tumors. Treatment, particularly the combination therapy, was associated with a decrease in QOL.

Activity of multitargeted antifolate (pemetrexed disodium, LY231514) in patients with advanced colorectal carcinoma: results from a phase II study.

BACKGROUND: The aim of this study was to confirm the activity and assess the safety profile of multitargeted antifolate (MTA) for patients with metastatic colorectal adenocarcinoma. METHODS: Forty-six patients were enrolled in the study, 35 with colon and 11 with rectal carcinoma. Adjuvant therapy was allowed if completed 1 year previously. Patients received MTA 600 mg/m(2) as a 10-minute intravenous infusion once every 21 days. Blood samples were taken every cycle for pharmacokinetic and vitamin metabolite assays. RESULTS: Among 39 patients eligible for efficacy analysis, 1 complete response and 5 partial responses were identified, for an overall response rate of 15.4% (95% confidence interval [CI], 4.1-26. 7%) for all patients. Fifteen patients had stable disease, with 9 living longer than 1 year. The median survival was 16.2 months (95% CI, 10.5-17.0%); 65% of patients were alive at 1 year, and the median time to progression was 4.4 months (range, 3.2-5.7 months). The main toxicities were hematologic, with common toxicity criteria (CTC) Grades 3 or 4 noted as follows: thrombocytopenia (18%), neutropenia (55%), and anemia (18%). Nonhematologic toxicities included Grade 2 or 3 skin reaction (53%), ameliorated by dexamethasone, and Grade 3 transaminases (23%). Dose omissions were not required and 21% of doses were reduced. CONCLUSIONS: MTA has clear activity in patients with colorectal carcinoma, and encouraging survival times were noted. MTA was well tolerated in this patient group, but myelosuppression was frequent. Toxicity may be increased with folate deficiency.

Phase II study of the multitargeted antifolate LY231514 (ALIMTA, MTA, pemetrexed disodium) in patients with advanced pancreatic cancer.

PURPOSE: To determine the safety and activity of LY231514 (ALIMTA, MTA, pemetrexed disodium, Eli Lilly and Co., Indianapolis, IN) in chemotherapy-naïve patients with advanced pancreatic cancer. PATIENTS AND METHODS: Patients with unresectable or metastatic pancreatic cancer received LY231514 600 mg/m2 as a 10-minute infusion every three weeks. RESULTS: Forty-two patients were enrolled in this phase II trial. The median age was 60.3 (range 37-77) years; 79% had metastatic disease. Neutropenia was common (40% of patients > or = grade 3) but infectious complications were rare. Significant anemia or thrombocytopenia occurred in < 20% of patients. Non-hematologic toxicities included grade 2 or 3 skin reaction which was ameliorated by dexamethasone. Elevations of bilirubin or transaminases were infrequent (< 25% of patients) and did not require dose reductions or treatment delays. Thirty-five patients received two cycles of therapy and were evaluable for response. One complete (duration 16.2 months) and one partial (duration 6.9 months) were observed resulting in an objective response rate of 5.7% for evaluable patients. In addition, 17 patients (40%) had stable disease that lasted > or = 6 months in 5 patients. The median survival was 6.5 months, with 28% of patients alive at one year. CONCLUSIONS: LY231514 is a well-tolerated agent with minimal objective antitumor activity in pancreatic cancer. The median and one year survival times, which may be important indicators in phase II trials of new agents, are of interest. Combination trials of LY231514 in pancreatic cancer are planned.
