Meta-Analysis on the Application Value of Collaborative Nursing in Postcolostomy Nursing of Patients with Colorectal Cancer

OBJECTIVE

To systematically evaluate the effect of collaborative nursing on self-care ability of postcolostomy patients with colorectal cancer (CRC).

METHODS

PubMed, Web of Science, Embase, China National Knowledge Infrastructure, and Wanfang databases were searched to collect relevant literatures on randomized controlled trials of postcolostomy patients with CRC. The search period was started from 2010 to 2021. Statistical analysis was performed on the data extracted from the comprehensive meta-analysis with STATA 16.0 analysis software.

RESULTS

As a result, it was found that the incidence of adverse reactions in the control group was higher than that in the treatment group. Seven studies included the preintervention self-care concept and preintervention self-care skills. Six studies included preintervention self-care responsibility and preintervention exercise of self-care agency (ESCA) scale. In the comparison among the concept of self-care after intervention, self-care skills, self-care responsibility, and ESCA scale, all of them had higher scores in the treatment group than in the control group (P < 0.05). It fully explains that collaborative nursing can significantly improve the evaluation indicators of patients' self-care ability and reduce patient complications.

CONCLUSION

The application of collaborative nursing in the nursing work of patients with CRC after colostomy can significantly reduce the incidence of adverse nursing reactions.

Survivors' Perceptions of Quality of Colorectal Cancer Care by Sexual Orientation

OBJECTIVE

The objective of this study was to assess sexual minority and heterosexual survivors' perceived quality of cancer care and identify demographic, clinical, and psychosocial characteristics associated with patient-centered quality of care.

MATERIALS AND METHODS

Four cancer registries provided data on 17,849 individuals who were diagnosed with stage I, II, or III colorectal cancer an average of 3 years prior and resided in predetermined diverse geographic areas. A questionnaire, which queried about sexual orientation and other eligibility criteria was mailed to all cancer survivors. Of these, 480 eligible survivors participated in a telephone survey. Quality of cancer care was defined by 3 measures of interpersonal care (physician communication, nursing care, and coordination of care) and by rating cancer care as excellent. We used generalized linear models and logistic regression with forward selection to obtain models that best explained each quality of care measure.

RESULTS

Sexual minority survivors rated physician communication, nursing care, and coordination of care similarly to heterosexual survivors, yet a significantly higher percentage of sexual minority survivors rated the overall quality of their cancer care as excellent (59% vs. 49%). Sexual minority survivors' greater likelihood of reporting excellent care remained unchanged after adjusting for demographic, clinical, and psychosocial characteristics.

CONCLUSIONS

Sexual minority survivors' ratings of quality of colorectal cancer care were comparable or even higher than heterosexual survivors. Sexual minority survivors' reports of excellent care were not explained by their interpersonal care experiences.

The Effects of the Nurse Navigation Program in Promoting Colorectal Cancer Screening Behaviors: a Randomized Controlled Trial

Although screening programs are known and recommended for the early detection of colorectal cancer (CRC), the screening rates for the fecal occult blood test (FOBT) and colonoscopy are very low among adult individuals. Navigation programs, also known as individualized counseling, have recently begun to be used for increasing screening rates. The purpose of this study was to compare the efficacy of the Nurse Navigation Program versus usual care on CRC screening participation and movement in stage of adoption for CRC screening and to examine perceived benefits of and barriers to CRC screening. This study was designed in line with a pre- and posttest two-group methodology. A total of 110 participants (55 nurse-navigated and 55 non-navigated patients) were studied. Data were collected using the following three tools: a sociodemographic information form, the Harvard Colorectal Cancer Risk Assessment Tool, and Instruments to Measure Colorectal Cancer Screening Benefits and Barriers. Following the Nurse Navigation Program, the FOBT (82 and 84%, respectively) and colonoscopy completion rates (15 and 22%, respectively) were significantly higher in the nurse-navigated group than in the non-navigated group at 3 and 6 months follow-up. Following the program, the benefit perceptions of the nurse-navigated group about CRC screening were improved, and their barrier perceptions were reduced. The results showed that the Nurse Navigation Program had significant effects on CRC screening behavior and health-related beliefs concerning CRC screening. Further assessment of the Nurse Navigation Program in different groups should be performed to observe its effects.

A Descriptive, Cross-sectional Study Among Chinese Patients to Identify Factors that Affect Psychosocial Adjustment to an Enterostomy

Physiological, psychological, and social problems may affect adaptation to living with a stoma. A descriptive, cross-sectional study was conducted between March 2017 and June 2017 among patients culled from a manufacturer's database to identify factors that influence psychosocial adjustment in Chinese patients with an enterostoma. Patients with a history of ostomy surgery ≥1 month prior and who were ≥18 years of age, completed a primary school education, and able to communicate in Chinese were eligible to participate unless they had a history of psychosis, cognitive impairment, or participation in other research programs. After providing informed consent, participants completed a questionnaire that addressed demographic (age, gender, employment, educational level, marital status, medical payment method, living status, and area of residence) and stoma-related (date of surgery, preoperative stoma siting, ostomy appliance type, peristomal complications, regular defecation, stoma self-care ability, stoma-related communication with medical staff, level of understanding regarding stoma knowledge and care skills, appliance change knowledge/experience, and leakage history) factors. Social support was assessed using the 10-item Social Support Revalued Scale (SSRS), and 3 dimensions of adjustment (acceptance, continuous worry, and positive life attitude) were assessed using the 20-item Chinese version of the Ostomy Adjustment Inventory (OAI). Questionnaires were administered via an online survey platform. Data were analyzed descriptively, and single-factor analysis and stepwise multiple linear regression were applied to identify the factors that influenced the adjustment level. Incomplete (missing >2 questions), incorrect, or hastily completed (within 600 seconds) records were excluded from analysis. Of the 1109 persons who returned the questionnaire, 1010 (91.1%) completed the entire survey (564 men [55.8%] and 446 women [44.2%], mean age 56.62 ± 15.62 years); 823 (81.5%) had a colostomy and 187 (18.5%) had an ileostomy. The OAI dimension continuous worry was negatively and significantly associated with all 3 dimensions of the SSRS, including subjective support (r = 0.259), objective support (r = 0.259), and utilization of support (r = 0.289), while the dimension acceptance was positively associated with both subjective support (r = 0.082) and objective support (r = 0.074) (all P values <.05). Using multiple linear regression, residence area, peristomal complication, regular defecation, leaking, self-care ability, communication with medical staff regarding ostomy, understanding knowledge or skill needed for stoma care, utilization of social support, and total score of social support were found to be significantly associated with ostomy adjustment level (all P values <.05). Patients living in an urban area, with no history of peristomal complications, who had regular defecation, had not experienced leaking, had better self-care ability, frequently communicated with medical staff, had a high level understanding about knowledge or skill of stoma, and had higher social support scores had higher adjustment scores. Knowledge of the factors that enhance or hinder adaptation of the patient to the ostomy is an important tool in the clinician's care armamentarium.

Liposomal Irinotecan: Nursing Considerations in an Outpatient Cancer Center

Recent approaches in treating pancreatic adenocarcinoma, an aggressive disease with limited survival, include the use of liposomal irinotecan as an option when first-line therapy has failed. Liposomal irinotecan has been approved in combination with 5-fluorouracil and leucovorin for patients with metastatic pancreatic cancer. Liposomal irinotecan is a newer therapy requiring oncology nurses to obtain knowledge and skills for proper administrating, monitoring of hypersensitivity reactions during infusion, managing side effects, and providing patient education. Nursing considerations when administering this drug include infusion time, premedication, risk for hypersensitivity reactions and adverse events, and side effects.

Long-term use of antibiotics and risk of colorectal adenoma

OBJECTIVE

Recent evidence suggests that antibiotic use, which alters the gut microbiome, is associated with an increased risk of colorectal cancer. However, the association between antibiotic use and risk of colorectal adenoma, the precursor for the majority of colorectal cancers, has not been investigated.

DESIGN

We prospectively evaluated the association between antibiotic use at age 20-39 and 40-59 (assessed in 2004) and recent antibiotic use (assessed in 2008) with risk of subsequent colorectal adenoma among 16 642 women aged ≥60 enrolled in the Nurses' Health Study who underwent at least one colonoscopy through 2010. We used multivariate logistic regression to calculate ORs and 95% CIs.

RESULTS

We documented 1195 cases of adenoma. Increasing duration of antibiotic use at age 20-39 (ptrend=0.002) and 40-59 (ptrend=0.001) was significantly associated with an increased risk of colorectal adenoma. Compared with non-users, women who used antibiotics for ≥2 months between age 20 and 39 had a multivariable OR of 1.36 (95% CI 1.03 to 1.79). Women who used ≥2 months of antibiotics between age 40 and 59 had a multivariable OR of 1.69 (95% CI 1.24 to 2.31). The associations were similar for low-risk versus high-risk adenomas (size ≥1 cm, or with tubulovillous/villous histology, or ≥3 detected lesions), but appeared modestly stronger for proximal compared with distal adenomas. In contrast, recent antibiotic use within the past four years was not associated with risk of adenoma (ptrend=0.44).

CONCLUSIONS

Long-term antibiotic use in early-to-middle adulthood was associated with increased risk of colorectal adenoma.

Colorectal cancer screening: Using evidence-based guidelines

Colorectal cancer is the third most common cancer diagnosed in men and women. There are multiple options for prevention and early detection. Evidence-based guidelines are available to select the best option based on personal and family history. NPs should utilize these guidelines in clinical practice to select the appropriate screening for their patients.

Nurse navigators in early cancer care: a randomized, controlled trial

PURPOSE

To determine whether a nurse navigator intervention improves quality of life and patient experience with care for people recently given a diagnosis of breast, colorectal, or lung cancer.

PATIENTS AND METHODS

Adults with recently diagnosed primary breast, colorectal, or lung cancer (n = 251) received either enhanced usual care (n = 118) or nurse navigator support for 4 months (n = 133) in a two-group cluster randomized, controlled trial with primary care physicians as the units of randomization. Patient-reported measures included the Functional Assessment of Cancer Therapy-General (FACT-G) Quality of Life scale, three subscales of the Patient Assessment of Chronic Illness Care (PACIC), and selected subscales from a cancer adaptation of the Picker Institute's patient experience survey. Self-report measures were collected at baseline, 4 months, and 12 months. Automated administrative data were used to assess time to treatment and total health care costs.

RESULTS

There were no significant differences between groups in FACT-G scores. Nurse navigator patients reported significantly higher scores on the PACIC and reported significantly fewer problems with care, especially psychosocial care, care coordination, and information, as measured by the Picker instrument. Cumulative costs after diagnosis did not differ significantly between groups, but lung cancer costs were $6,852 less among nurse navigator patients.

CONCLUSION

Compared with enhanced usual care, nurse navigator support for patients with cancer early in their course improves patient experience and reduces problems in care, but did not differentially affect quality of life.

Time costs associated with informal care for colorectal cancer: an investigation of the impact of alternative valuation methods

BACKGROUND

A societal perspective in economic evaluation necessitates that all resources associated with a disease or intervention should be valued; however, informal care time costs are rarely considered.

OBJECTIVE

We estimated time allocated to care by informal carers of colorectal cancer survivors; and investigated the impact of applying alternative valuation methods to this time.

METHODS

Colorectal cancer cases (ICD10 C18-C20) diagnosed 6-30 months previously and identified from the National Cancer Registry Ireland were invited to provide details of informal carers. Carers completed a postal questionnaire. Time estimates per week associated with hospital-related and domestic-related care activities were collected for two phases: diagnosis and initial treatment (initial 3 months) and ongoing care (previous 30 days). Seven valuation scenarios, based on variants of the opportunity cost approach (OCA), and the proxy good approach (PGA), were considered. The base-case was OCA with all carer time valued at the average national wage.

RESULTS

We received 154 completed questionnaires (response rate = 68 %). Average weekly time allocated to caring was 42.5 h in the diagnosis and initial treatment phase and 16.9 h in the ongoing care phase. Under the base-case, average weekly time costs were <euro>295 (95 % CI 255-344) for hospital-related activities and <euro>630 (95 % CI 543-739) for domestic-related activities in the diagnosis and initial treatment phase and <euro>359 (95 % CI 293-434) in the ongoing care phase. PGA estimates were 23 % below the base-case. Only one alternative scenario (occupation and gender-specific wages for carers in paid work and replacement wages for non-working carers) surpassed base-case costs, and the difference was modest.

CONCLUSIONS

Overall, significant time is associated with informal caring in colorectal cancer. Different time valuation methods can produce quite different cost estimates. A standardised methodology for estimating informal care costs would facilitate better integration of these into economic evaluations.

Disgust and behavioral avoidance in colorectal cancer screening and treatment: a systematic review and research agenda

BACKGROUND

The emotion of disgust appears to promote psychological and behavioral avoidance, a dynamic that has significant implications in physical and psychological outcomes in colorectal cancer (CRC). Patients, caregivers, and health professionals alike are all potentially susceptible to responding with disgust and the associated avoidance.

OBJECTIVE

This article aimed to review the early-stage literature related to disgust and CRC, consider the clinical implications, and suggest an appropriate research agenda.

METHODS

Given limited research in this area, a systematic review of the literature was broadened to include disgust and all cancers. MEDLINE, Web of Science, SCOPUS, and ProQuest Dissertations and Theses databases were searched, with additional works sourced by reviewing citation lists and/or by contacting the lead authors.

RESULTS

Nine studies were identified relating to disgust and cancer screening, and 6 related to disgust and cancer treatment. Two broad findings emerged: (1) disgust appears to be promoting aversion to (and avoidance of) CRC screening, and (2) several known elicitors of disgust are widely apparent in CRC contexts.

CONCLUSIONS

Disgust likely represents a key emotional substrate for avoidance among CRC patients, caregivers, and health professionals. Further research is required to identify disgust's elicitors and effects in CRC contexts, informing interventions that target early identification of persons at risk of maladaptive outcomes. Exposure therapies and mindfulness training may be well suited to treating disgust-generated avoidance.

IMPLICATIONS FOR PRACTICE

Disgust has significant implications in CRC contexts. Oncology nurses are uniquely positioned to guide clinical interventions and ultimately improve outcomes in this area.

[Nursing care adapted to different types of stoma]

As soon as the patient leaves the operating theatre, in the recovery room, then in the surgical clinical unit, nurses carry out stoma care and monitor the possible occurrence of complications. Stoma therapists educate patients in caring for the stoma themselves, advise them in the choice of equipment and support them as they regain autonomy.

[The training of stomatherapy nurses]

Advising and educating patients and resource people, providing information and training, leading a public-private-freelance and associative care network as well as being involved in a research process are essential elements of the practice of a stoma therapist. Although based on specific training this practice is not so much a speciality as a specificity.

[Therapeutic education at the heart of the patient treatment pathway]

The surgical treatment of bowel cancer often results in a digestive stoma, either temporary or permanent. Stoma patients must learn to live with this changed body and intestinal function. They must also adapt their lifestyle to these changes. It is in this direction which the stoma therapy nurse supports the patient.

[The peer support role of patient experts]

As a complement to the care provided by stomatherapy nurses, expert stoma patients lend an ear and provide precious peer support based on their own experience as a stoma patient. Trained in this particular approach, they adopt a course of action adapted to the needs of the patients visited during the perioperative period.

[The role of the stoma therapy nurse in the preoperative period]

Based on clinical reasoning and nursing expertise, stomatherapy care helps to improve the stoma patient's quality of life. In the preoperative period, the stoma therapist seeks to expand on the information provided by the surgeon, to establish a helping relationship while preparing already, the stoma patient's future autonomy.

[Diagnosis and treatments for patients suffering from bowel cancer]

After lung cancer, bowel cancer is the second most deadly cancer in France. Since 2009, it has been subject to an organised screening programme aimed at reducing mortality rates. The nursing care brings together a multi-disciplinary team which, from the diagnosis announcement and throughout the treatment, seeks to place the patient at the centre of the therapeutic project.

[Announcement of bad news and patient support]

Being unprepared for the announcement of bad news can influence patients' perception of their illness and upset their psychological balance. While the announcement of the diagnosis, the prognosis and the treatment remains a medical act, the psychological preparation around this announcement is a nursing act which forms an integral part of the nursing role.

Best practice in colorectal cancer care

Nurses need up-to-date knowledge of colorectal cancer. This article provides an overview of the aetiology and risk factors for this disease, diagnostic and staging investigations, treatment options and future care. Managing colorectal cancer is complex. Patients can have a range of healthcare needs. Nurses play an increasingly important role in informing, supporting and coordinating care to improve patients' quality of life.

Opening doors for nonphysician colonoscopists

The current need for colonoscopies is high and steadily growing. Many healthcare facilities are finding that there is a shortage of specialized physicians to perform this procedure. By training nonphysician providers who have previously screened for colorectal cancer and performed colonoscopies safely and accurately, this shortage can be eliminated.

Sociocultural differences and colorectal cancer screening among African American men and women

PURPOSE/OBJECTIVES

To examine sociocultural factors that influence an informed decision about colorectal cancer (CRC) screening among African American men and women.

DESIGN

Descriptive, cross-sectional.

SETTING

A medical center, a National Cancer Institute-designated comprehensive cancer center, and various social organizations and barbershops in a midwestern city of the United States.

SAMPLE

A purposive sample of African American women (n = 65) and African American men (n = 64) aged 50 years and older.

METHODS

Participants completed a self-administered survey.

MAIN RESEARCH VARIABLES

Cultural identity, CRC beliefs, family support, and informed decision.

FINDINGS

Family support was positively related to CRC beliefs among participants, and CRC beliefs were positively related to an informed decision. However, among men, family support positively related to an informed decision about CRC screening. In addition, t-test results indicated that the men and women were significantly different. Family support predicted CRC beliefs among men (p < 0.01) and women (p < 0.01). CRC beliefs predicted CRC screening informed decisions among men (p < 0.01) and women (p < 0.05). However, the accounted variance was dissimilar, suggesting a difference in the impact of the predictors among the men and women.

CONCLUSIONS

Family support has a significant impact on CRC beliefs about CRC screening among African Americans. However, how men and women relate to the variables differs.

IMPLICATIONS FOR NURSING

To improve CRC screening rates, informed decision-making interventions for African Americans should differ for men and women and address family support, CRC beliefs, and elements of cultural identity.

[Meta-analysis based on individual patient data: example of advanced colorectal cancer]

The authors mention the existing methods to perform meta-analysis, and show that meta-analysis based on individual patient data (IPD meta-analyses) are the most reliable. Taking the example of 4 successive meta-analysis of clinical trials in advanced colorectal cancer, they illustrate the possibilities of IPD meta-analysis. They conclude that meta-analysis are a powerful tool not only to confirm small differences between treatment modalities, but also to generate hypothesis, to perform exploratory subgroup analysis, and to study potential surrogate endpoints.

Implementation and evaluation of a pilot education programme in colorectal cancer management for nurses in Scotland

This paper describes the results of an evaluation of a nursing education programme for nurses caring for patients with colorectal cancer. A sample of 67 registered nurses from 6 location sites within the 3 Regional Cancer Networks in Scotland were recruited to the pilot. The programme was adapted from an evidence-based education manual for nurses in the management of colorectal cancer developed by the European Oncology Nursing Society as part of a Nursing in Colorectal Cancer Initiative (NICCI) [Hawthorn, J., Redmond, K., 1999. A Guide to Colorectal Cancer. AstraZeneca Oncology, UK]. The format for evaluating the programme was based on the TELER method of treatment evaluation [Le Roux, A.A., 1995. TELER: the concept. Physiotherapy 79 (11), 755-758] that had previously been developed along side the training manual [Grocott, P., Richardson, A., Ambaum, B., Kearney, N., Redmond, K, 2001a. Nursing in colorectal cancer initiative--the audit phase. Part 1. Development of the audit tool. European Journal of Oncology Nursing 5 (2), 100-111; Grocott, P., Richardson, A., Ambaum, B., Kearney, N., Redmond, K., 2001b. Nursing in colorectal cancer initiative: the audit phase. Part 2. Content validity of the audit tool and implications of the standards set for clinical practice. European Journal of Oncology Nursing 5 (3), 165-173] for cytotoxic chemotherapy to provide the NICCI Audit Tool (Le Roux, 2003). This model was developed further in the current study to include the domains of: Disease, Diagnosis and Staging, Treatment, Nursing Issues and General Issues. Data were analysed descriptively and are discussed. Overall the results from this study demonstrate a statistically significant improvement in disease-related knowledge (p=<0.001) and in the best practice statements for nursing issues (p=<0.001) and general issues (including attitudes) (p=0.023) that were maintained at four months post completion of the course.

Targeting the epidermal growth factor receptor in colorectal carcinoma

Colorectal cancer continues to be a common cause of death in this country, accounting for more than 55,000 deaths in 2006. The introduction of targeted biologic therapies, such as the epidermal growth factor receptor and tyrosine kinase inhibitors, has expanded the treatment options and has shown promise for patients with advanced disease. This article gives a history of the treatment of colorectal cancer, with a focus on the efficacy and toxicity of epidermal growth factor receptor inhibitors and their implications for the nursing community.

A nurse-/pharmacy-led capecitabine clinic for colorectal cancer: Results of a prospective audit and retrospective survey of patient experiences

Oral chemotherapy agents provide patients with choice and home-based therapy but demand greater emphasis on patient support and education to minimise toxicities. To meet this demand, a nurse-/pharmacy-led clinic was established at the Beatson Oncology Centre in 2003 for the provision of oral capecitabine to metastatic colorectal cancer patients to provide a controlled and supportive environment. We conducted a prospective audit of 52 patients attending the clinic from March 2003 to June 2004 and a retrospective survey of patient experiences to assess clinic effectiveness. Of 52 patients, 79% completed at least 3 cycles of treatment (mean 3.5). Capecitabine was well tolerated. The dose was reduced on at least one occasion in 15 (29%) patients and 17 (30%) patients experienced at least one delay. Patient satisfaction, indicated by questionnaire responses (n=27), was high. Most patients (> or =85%) thought that the service provision was useful and well organised. The results indicate that a nurse-/pharmacy-led clinic for the provision of home-based oral capecitabine is safe, effective and acceptable to most patients. The success of this clinic can provide a model for use in other centres and in other types of cancer, such as breast cancer, where oral chemotherapy is a treatment option.

A Qualitative Study of Caregivers' Experiences With Newly Diagnosed Advanced Colorectal Cancer

PURPOSE/OBJECTIVES

To report on a descriptive, qualitative study of 14 caregivers of patients newly diagnosed with advanced colorectal cancer.

RESEARCH APPROACH

Qualitative.

SETTING

One urban ambulatory cancer center in the northeastern United States.

PARTICIPANTS

14 identified caregivers of patients newly diagnosed with stage III or IV colorectal cancer.

METHODOLOGIC APPROACH

Semistructured interviews were taped recorded. Interviewers asked participants to describe their experiences caring for a loved one with colorectal cancer. Thematic content analysis with inductive coding was used to code the transcribed interview data. Throughout the data-coding process, emics in each category were compared within and between categories to maximize the fit of participants' data. Categories were reviewed in a final stage of analysis and further organized into domains from which the core category was derived.

MAIN RESEARCH VARIABLES

Caregiver experiences of living with a person with colorectal cancer, effect on daily living, coping strategies used, and effect on children.

FINDINGS

The coded interview data yielded three domains: Experiencing Total Disruption of My Life, Staying Positive, and Attempting to Keep Family and Children's Routines as Normal as Possible. The core category that explained study participants' caregiving experiences was "balancing caregiving activities and disruptions while dealing positively with daily demands and personal impact."

CONCLUSIONS

The dominant experiences of the participants focused on coming to terms with the disease's disruption in their lives, attempting to deal positively with the effect of the disease, and maintaining normalcy in family life.

INTERPRETATION

Targeted assessment of caregivers' needs is important in the three dimensions of the study domains. Clinicians who work with caregivers of patients with cancer should offer direct support because caregivers cope with the care of their loved one and struggle with their own distress and with maintaining normal family life. Findings suggest the importance of offering psychosocial support to caregivers and providing guidance to caregivers for support of their children and families.

Open-label phase III trial of panitumumab plus best supportive care compared with best supportive care alone in patients with chemotherapy-refractory metastatic colorectal cancer

PURPOSE

Panitumumab is a fully human monoclonal antibody directed against the epidermal growth factor receptor (EGFR). We compared the activity of panitumumab plus best supportive care (BSC) to that of BSC alone in patients with metastatic colorectal cancer who had progressed after standard chemotherapy.

PATIENTS AND METHODS

We randomly assigned 463 patients with 1% or more EGFR tumor cell membrane staining, measurable disease, and radiologic documentation of disease progression during or within 6 months of most recent chemotherapy to panitumumab 6 mg/kg every 2 weeks plus BSC (n = 231) or BSC alone (n = 232). Tumor assessments by blinded central review were scheduled from week 8 until disease progression. The primary end point was progression-free survival (PFS). Secondary end points included objective response, overall survival (OS), and safety. BSC patients who progressed could receive panitumumab in a cross-over study.

RESULTS

Panitumumab significantly prolonged PFS (hazard ratio [HR], 0.54; 95% CI, 0.44 to 0.66, [P < .0001]). Median PFS time was 8 weeks (95% CI, 7.9 to 8.4) for panitumumab and 7.3 weeks (95% CI, 7.1 to 7.7) for BSC. Mean (standard error) PFS time was 13.8 (0.8) weeks for panitumumab and 8.5 (0.5) weeks for BSC. Objective response rates also favored panitumumab over BSC; after a 12-month minimum follow-up, response rates were 10% for panitumumab and 0% for BSC (P < .0001). No difference was observed in OS (HR, 1.00; 95% CI, 0.82 to 1.22), which was confounded by similar activity of panitumumab after 76% of BSC patients entered the cross-over study. Panitumumab was well tolerated. Skin toxicities, hypomagnesaemia, and diarrhea were the most common toxicities observed. No patients had grade 3/4 infusion reactions.

CONCLUSION

Panitumumab significantly improved PFS with manageable toxicity in patients with chemorefractory colorectal cancer.

Outcomes in 2748 patients referred to a colorectal two-week rule clinic

OBJECTIVE

To assess the 3-year outcomes of a nurse-led, one-stop, 2-week rule (TWR) clinic for suspected colorectal cancer (CRC) in a large teaching hospital.

METHOD

Data were collected prospectively from January 2002 to December 2004. In total, 2748 patients were seen over the 3-year period. The ratio of male:female subjects was 1190:1558 (43%:57%). Median age at presentation was 66 years (range 17-96).

RESULTS

A total of 1363 (49.6%) nonconforming referrals were made; 1300 patients (47.3%) underwent flexible sigmoidoscopy during their initial assessment in clinic; 1439 patients (52.4%) underwent a barium enema during the course of their investigation; 2503 patients (91.1%) were seen within 14 working days. The median overall wait for the initial clinic appointment was 10 days. The annual number of patients seen was similar over the 3-year period. A total of 174 cancers (6.3%) were identified which accounted for 36.4% of all CRCs diagnosed during the study period. Nineteen cancers presented in the nonconforming group (1.6% of all non-conforming patients). Rectal tumours accounted for 59.8% (n = 104) of all cancers diagnosed while right-sided tumours accounted for only 10.9% (n = 19). Advanced tumours accounted for 73.0% (n = 127) of the total; 133 (76.4%) cancer patients underwent some form of surgical intervention.

CONCLUSION

A specialist nurse-led, one-stop TWR clinic for suspected colorectal cancer is sustainable and can be run successfully with over 90% of referrals seen within the targeted time period. The proportion of non-conforming referrals was high and a large number of advanced and unstaged tumours was observed. Low numbers of proximal tumours were detected.

Achieving long-term compliance with colonoscopic surveillance guidelines for patients at increased risk of colorectal cancer in Australia

We have previously demonstrated that we could improve colonoscopic surveillance practice for patients at increased risk of colorectal cancer by the adoption of guidelines, facilitated by a nurse co-ordinator. This study was to determine whether we could sustain this improvement over a longer period (4 years). All colonoscopic surveillance decisions made by the co-ordinated colorectal screening programme of our hospital between 2000 and April 2004 were reviewed. Reasons for variance were recorded, and surveillance decisions made in the last 4 months of the study time were compared with decisions made 4 years previously, both before and after the introduction of the co-ordinated programme. Between 2000 and 2004, 1794 surveillance decisions were made with variance occurring in 100. In the last 4 months of the period of study, 98% of decisions matched guidelines, suggesting that the improvement made following the adoption of the guidelines (45-96% p < 0.05) could be maintained. Reasons for variance from guidelines included a belief that the particular clinical scenario was not covered in the guidelines, disagreement with the guidelines or patient anxiety. Adherence to evidence based medicine guidelines for colonoscopy surveillance can be maintained over time at a high level. A number of clinical scenarios are not covered adequately by the existing guidelines and continue to generate disagreement amongst clinicians.

Advanced Colorectal Cancer: Current Treatment and Nursing Management With Economic Considerations

Colorectal cancer is one of the most common cancers affecting men and women in the United States. In 2005, 10% of all new cancer cases in men will be colorectal; for women, 11% of new cases will be colorectal. The disease is the third most frequent cancer occurring in both sexes. Colorectal cancer also is the third most frequent cause of death for men and women, and more than 56,000 cancer deaths in 2005 will be attributed to colorectal cancer. Chemotherapy options for treatment of the disease remained relatively stagnant until the approval of irinotecan in 1996 followed by capecitabine, oxaliplatin, and the new targeted agents. The new agents have improved efficacy of treatment for colorectal cancer and the lives of patients with advanced disease. With the new options for treatment come increased nursing and patient-teaching responsibilities, as well as increased costs associated with the newer drugs in the armamentarium of chemotherapy agents. Formulary budgets are seeing dramatic rises in expenditures for the new, targeted therapy treatments; discussion of the most appropriate therapies may be considered. This article will discuss epidemiology of colorectal cancer, treatment options in advanced colorectal cancer, and nursing care crucial to patients undergoing chemotherapy. Discussion of economic impact also will be presented.

Hypersensitivity Reactions to Oxaliplatin: What Nurses Need to Know

Colorectal cancer (CRC) is the third-leading cause of cancer death in the United States. With the advent of new chemotherapy drugs, such as oxaliplatin, for CRC, disease-free and long-term survival has improved in this patient population. As oxaliplatin use increases, more hypersensitivity reactions may be expected. The etiology of these reactions is unclear but may be a combination of immunologic responses. Pretreatment, treatment, and desensitization protocols are available to prevent and treat hypersensitivity reactions. Nurses' rapid assessment and management of infusion-related hypersensitivity reactions are vital to ensuring the safe administration of oxaliplatin.

Oxaliplatin: A Novel Platinum Analog With Activity in Colorectal Cancer

PURPOSE/OBJECTIVES

To review selected recent data pertaining to the use of oxaliplatin in colorectal cancer and its implications for oncology nursing.

DATA SOURCES

Published articles, abstracts, and conference proceedings.

DATA SYNTHESIS

Colorectal cancer accounts for about 15% of all new cancers. The search for more effective chemotherapy regimens is ongoing. Oxaliplatin, a member of the diaminocyclohexane family of platinum compounds, demonstrates cytotoxic efficacy and a well-tolerated safety profile.

CONCLUSIONS

Oxaliplatin is effective in chemotherapy-naive patients with advanced colorectal cancer, as well as in those refractory to previous treatment with 5-fluorouracil (5-FU); the drug also is effective in combination with 5-FU and leucovorin for the treatment of advanced colorectal cancer.

IMPLICATIONS FOR NURSING

Nurses must be highly knowledgeable about oxaliplatin regimens and schedules, the associated side effects, and recommended strategies for symptom management. This article can help nurses to understand and communicate the benefits and risks associated with oxaliplatin-based therapies to colleagues and patients.
