Canada is a pioneer in remote cancer care delivery to underserved populations; however, it is trailing behind on policies that would support clinicians in providing care using distance technologies. The current policy framework is disjointed, and discussions by professional boards about online jurisprudence associated with licensure appear to be regressive. We hope that by addressing the discrepancies in interjurisdictional practice and focusing on the key issue of “where therapy resides,” we will be able to nudge dialogue and thinking closer toward the reasoning and recommendations of national telehealth organizations. We present this discussion of jurisdictional issues and e-health practice in the context of a pan-Canadian online support program developed for cancer patients and family members. Although the present paper uses online support groups as a springboard to advocate for e-health, it ultimately addresses a broader audience: that of all Canadian health care stakeholders.

Purpose

The purpose of the present study was to assess whether current cancer follow-up care practices meet the needs of young adult cancer survivors in Canada.

Methods

This qualitative study used a constructivist grounded theory framework to analyze telephone interviews with cancer survivors from across Canada diagnosed between the ages of 18 and 39 years. The focus was specifically on cancer follow-up care (cfc).

Results

Interviews were conducted with 55 participants, and 53 interviews were used for the analysis. The overall theme that emerged from the data was the lack of age-specific cfc. Some of the subthemes that emerged were the absence or inadequacy of fertility and infertility treatment options; of psychological services such as family, couples, and sexuality counseling; of social supports such as assistance with entry or re-entry into the education system or workplace; of access to supplemental health insurance; and of survivorship care plans. Based on the data resulting from the interviews, we developed a conceptual model of young-adult cfc incorporating the major themes and subthemes that emerged from our study. The proposed model aims to ensure a more age-appropriate and comprehensive approach to cfc for this group of cancer patients.

Conclusions

Current Canadian cfc practices are inadequate and do not provide comprehensive care for young adult cancer survivors in Canada. The conceptual model presented here aims to ensure a more comprehensive approach to cfc that meets the needs of this unique cancer population and reduces further possible physical, psychological, or social cancer sequelae.

Background

Nab-paclitaxel is a solvent-free, taxane-based chemotherapy approved for the treatment of metastatic breast cancer (mbc). This study reports clinical benefit and toxicities experienced by women with mbc treated with nab-paclitaxel at the Ottawa Hospital Cancer Centre.

Methods

Women with mbc treated with single-agent nab-paclitaxel between June 2006 and December 2010 were included in this analysis. Retrospective data obtained included demographics, disease characteristics, prior chemotherapy, nab-paclitaxel treatment, toxicity, and survival. Clinical benefit was defined as partial or complete response or stable disease (by clinical or radiologic evaluation, or both) at 6 months or more.

Results

Of 43 women (mean age: 57.0 years; range: 34–74 years), most had disease positive for estrogen or progesterone receptor (72.1%, 58.1%), or both. Nab-paclitaxel was administered weekly (qw: 44.2%), every 3 weeks (q3w: 46.5%), q3w switched to qw (7.0%), or qw switched to q3w (2.3%). Median duration of therapy was 5.1 months (qw) and 3.0 months (q3w). Sensory neuropathy was the primary toxicity (45.4% qw, 38.1% q3w; p = 0.62). Clinical benefit was observed in most women (76.2% qw, 57.1% q3w; p = 0.20). Women receiving nab-paclitaxel had a median overall survival of 13.6 months qw (range: 8.1–28.3 months) and 10.8 months q3w (range: 5.9–17.9 months; p = 0.03). Regardless of dosing schedule, women experiencing clinical benefit lived significantly longer than those not experiencing a benefit (17.3 months vs. 7.7 months; hazard ratio: 0.14; 95% confidence interval: 0.06 to 0.33).

Conclusions

Our clinical experience demonstrates that most women treated with nab-paclitaxel experienced some clinical benefit. Patients achieving clinical benefit lived significantly longer than those who did not. Nab-paclitaxel was well tolerated, with the primary toxicity being mild sensory neuropathy. Nab-paclitaxel represents another treatment option, with a favourable toxicity profile, for women with mbc.

Background

Adjuvant chemotherapy (act) for non-small-cell lung cancer (nsclc) is associated with improved survival in the general population, but may be underutilized. We explored the factors associated with referral to medical oncology and subsequent use of act among all patients with resected nsclc in Ontario, Canada.

Methods

The Ontario Cancer Registry was used to identify all incident cases of nsclc diagnosed in Ontario during 2004–2006. We linked electronic records of treatment and of physician billing to identify surgery, act, and medical oncology consultation. A multivariate logistic regression model was used to evaluate factors associated with referral to medical oncology and subsequent use of act.

Results

Among 3354 cases of nsclc resected in Ontario during 2004–2006, 1830 (55%) were seen postoperatively by medical oncology, and 1032 (31%) were treated with act. Patients more than 70 years of age were less likely than younger patients to have a consultation [odds ratio (or): 0.4; p < 0.001]. A higher proportion of cases with stage ii or iii nsclc than with stage i disease were referred (ors: 2.7, 2.0 respectively; p < 0.005). We observed substantial geographic variation in the proportion of surgical cases referred (range: 32%–88%) that was not explained by differences in case mix. Among cases referred to medical oncology, older patients (age 60–69 years, or: 0.4; age 70+ years, or: 0.1; p < 0.001) with greater comorbidity (Charlson comorbidity index: 3+; or: 0.5; p < 0.05) and a longer postoperative stay (median length of stay: 7+ days; or: 0.7; p = 0.001) were less likely to receive act. Use of act was greater in patients with stage ii or iii than with stage i disease (ors: 3.0, 2.7 respectively; p < 0.001); use also varied with geographic location (range: 46%–63%).

Conclusions

The initial decision to refer to medical oncology is associated with age and stage of disease, and those factors have an even greater effect on the decision to offer act. Comorbidity and postoperative length of stay were not associated with initial referral, but were associated with use of act in patients seen by medical oncology.

Background

Professional-led cancer support groups can improve quality of life and address unmet needs, but most Canadians affected by cancer do not have access to or do not make use of cancer support groups. A collaborative interdisciplinary team developed, operated, and evaluated Internet-based, professional-led, live-chat support groups (osgs) for cancer patients, caregivers, and survivors across Canada.

Objective

Our study aimed to report participant and participation characteristics in the pan-Canadian initiative known as CancerChatCanada, and to understand participant perspectives about the quality of communication and professional facilitation, overall satisfaction, and psychosocial benefits and outcomes.

Methods

Participants in osgs provided informed consent. Participant and participation characteristics were gathered from program data collection tools and are described using frequencies, means, and chi-squares. Patient, survivor, and caregiver perspectives were derived from 102 telephone interviews conducted after osg completion and subjected to a directed qualitative content analysis.

Results

The 55 professional-led osgs enrolled 351 participants from 9 provinces. More than half the participants came from rural or semirural areas, and more than 84% had no received previous cancer support. The attendance rate was 75%, the dropout rate was 26%, and 80% of participants were satisfied or very satisfied. The convenience and privacy of osgs were benefits. Meaningful communication about important and difficult topics, kinship and bonding with others, and improved mood and self-care were perceived outcomes.

Conclusions

Our results demonstrate that this collaborative initiative was successful in increasing reach and access, and that pan-Canadian, professional-led osgs provide psychosocial benefit to underserved and burdened cancer patients, survivors, and family caregivers.

Approximately 22,700 Canadian women were expected to be diagnosed with breast cancer in 2012. Despite improvements in screening and adjuvant treatment options, a substantial number of postmenopausal women with hormone receptor positive (hr+) breast cancer will continue to develop metastatic disease during or after adjuvant endocrine therapy. Guidance on the selection of endocrine therapy for patients with hr+ disease that is negative for the human epidermal growth factor receptor 2 (her2–) and that has relapsed or progressed on earlier nonsteroidal aromatase inhibitor (nsai) therapy is of increasing clinical importance. Exemestane, fulvestrant, and tamoxifen are approved therapeutic options in this context. Four phase iii trials involving 2876 patients—efect, sofea, confirm, and bolero-2—have assessed the efficacy of various treatment options in this clinical setting. Data from those trials suggest that standard-dose fulvestrant (250 mg monthly) and exemestane are of comparable efficacy, that doubling the dose of fulvestrant from 250 mg to 500 mg monthly results in a 15% reduction in the risk of progression, and that adding everolimus to exemestane (compared with exemestane alone) results in a 57% reduction in the risk of progression, albeit with increased toxicity. Multiple treatment options are now available to women with hr+ her2– advanced breast cancer recurring or progressing on earlier nsai therapy, although current clinical trial data suggest more robust clinical efficacy with everolimus plus exemestane. Consideration should be given to the patient’s age, functional status, and comorbidities during selection of an endocrine therapy, and use of a proactive everolimus safety management strategy is encouraged.

As cancer survivorship increases, there is a need for additional and more complex rehabilitation services. The Partners in Cancer Rehabilitation Research group held a 3-day invitational working meeting aimed at defining the state of the science in cancer rehabilitation research and identifying key areas for development of research and education. In May 2012, 29 participants gathered to present their current work, review a synthesis of the current literature, generate ideas about research and education gaps, and develop consensus on priority areas. The conclusion of the meeting was that a main research priority is to develop and test personalized rehabilitation interventions and brief measures to identify the presence and severity of disabling sequelae. The education consensus statement concluded that a clear description of cancer rehabilitation and its mandate should be developed as a precursor to education activities, including both a conceptualization of complex interdisciplinary rehabilitation and the roles of individual professions, and further, that there is a great need to increase awareness among health professionals, patients, and families of the need for and general effectiveness of cancer rehabilitation. Numerous specific recommendations were also put forward, and it is hoped that those recommendations will provide the foundation for a new and productive era of research and will play a role in the improvement of functional health and participation outcomes for cancer survivors.

Background

A growing body of evidence is demonstrating that the nitrogen-containing bisphosphonate zoledronic acid (zol) improves clinical outcomes in various cancer settings, including multiple myeloma. Those findings provided the rationale for conducting an open-label randomized controlled phase iii trial to evaluate the effect of zol on overall survival (os) and progression-free survival (pfs) in patients with previously untreated high-risk multiple myeloma.

Methods

The trial randomly assigned 308 adult patients less than 65 years of age with previously untreated symptomatic multiple myeloma (1:1) to receive zol 4 mg intravenously once every 28 days for 24 months (n = 151) or no zol (n = 157). Before autologous stem-cell transplantation (asct), all patients received a high-dose noncytotoxic induction regimen of dexamethasone, all-trans-retinoic acid, and interferon alpha 2b.

Results

After a median follow-up of 69.8 months (range: 36.5–96 months), the 10-year pfs (66% vs. 52%, p < 0.001) and os (67% vs. 48%, p < 0.001) rates were significantly higher in treated patients than in control patients. Overall response (77% zol vs. 75% control), complete response (52% vs. 46%), and very good partial response (25% vs. 29%) rates were similar between the groups. Treatment was generally well tolerated, with no reports of renal impairment or osteonecrosis of the jaw.

Conclusions

In symptomatic previously untreated multiple myeloma patients, zol combined with high-dose therapy followed by asct improved os and pfs without appreciable toxicity. These findings provide additional evidence of the meaningful anticancer activity of zol in this patient population.

Background

We evaluated clinical practice guideline (cpg) recommendations from Cancer Care Ontario’s Program in Evidence-Based Care (pebc) for molecularly targeted systemic treatments (tts) and subsequent funding decisions from the Ontario Ministry of Health and Long-Term Care.

Methods

We identified pebc cpgs on tt published before June 1, 2010, and extracted information regarding the key evidence cited in support of cpg recommendations and the effect size associated with each tt. Those variables were compared with mohltc funding decisions as of June 2011.

Results

From 23 guidelines related to 17 tts, we identified 43 recommendations, among which 38 (88%) endorsed tt use. Among all the recommendations, 38 (88%) were based on published key evidence, with 82% (31 of 38) being supported by meta-analyses or phase iii trials. For the 38 recommendations endorsing tts, funding was approved in 28 (74%; odds ratio related to cpg recommendation: 29.9; p = 0.003). We were unable to demonstrate that recommendations associated with statistically significant improvements in overall survival [os: 14 of 16 (88%) vs. 8 of 14 (57%); p = 0.10] or disease- (dfs) or progression-free survival [pfs: 16 of 21 (76%) vs. 3 of 5 (60%); p = 0.59] were more likely to be funded than those with no significant difference. Moreover, we did not observe significant associations between funding approvals and absolute improvements of 3 months or more in os [6 of 6 (100%) vs. 3 of 6 (50%), p = 0.18] or pfs [6 of 8 (75%) vs. 10 of 12 (83%), p = 1.00].

Conclusions

For use of tts, most recommendations in pebc cpgs are based on meta-analyses or phase iii data, and funding decisions were strongly associated with those recommendations. Our data suggest a trend toward increased rates of funding for therapies with statistically significant improvements in os.

Consider this scenario: A 35-year-old recently married woman is referred to a surgeon because of a growing breast lump. After a core biopsy shows cancer, she undergoes mastectomy for a 6-cm invasive lobular cancer that has spread to 8 axillary nodes. By the time she sees the medical oncologist, she is told that it is too late for a fertility consultation, and she receives a course of chemotherapy. At clinic appointments, she seems depressed and admits that her husband has been less supportive than she had hoped. After tamoxifen is started, treatment-related sexuality problems and the probability of infertility contribute to increasing strain on the couple’s relationship. Their marriage ends two years after the woman’s diagnosis.

Six years after her diagnosis, this woman has completed all treatment, is disease-free, and is feeling extremely well physically. However, she is upset about being postmenopausal, and she is having difficulty adopting a child as a single woman with a history of breast cancer. Could this woman and her husband have been offered additional personalized interventions that might have helped them better cope with the breast cancer diagnosis and the effects of treatment?

Compared with their older counterparts, young women with breast cancer often have greater and more complex supportive care needs. The present article describes the goals, achievements, and future plans of a specialized interdisciplinary program—the first of its kind in Canada—for women 40 years of age and younger newly diagnosed with breast cancer. The program was created to optimize the complex clinical care and support needs of this population, to promote research specifically targeting issues unique to young women, and to educate the public and health care professionals about early detection of breast cancer in young women and about the special needs of those women after their diagnosis.

Background

Neurocognitive impairments from brain tumours may interfere with the ability to drive safely. In 9 of 13 Canadian provinces and territories, physicians have a legal obligation to report patients who may be medically unfit to drive. To complicate matters, brain tumour patients are managed by a multidisciplinary team; the physician most responsible to make the report of unfitness is often not apparent. The objective of the present study was to determine the attitudes and reporting practices of physicians caring for these patients.

Methods

A 17-question survey distributed to physicians managing brain tumour patients elicited Respondent demographicsKnowledge about legislative requirementsExperience of reportingBarriers and attitudes to reporting

Fisher exact tests were performed to assess differences in responses between family physicians (fps) and specialists.

Results

Of 467 physicians sent surveys, 194 responded (42%), among whom 81 (42%) were specialists and 113 (58%) were fps. Compared with the specialists, the fps were significantly less comfortable with reporting, less likely to consider reporting, less likely to have patients inquire about driving, and less likely to discuss driving implications. A lack of tools, concern for the patient–physician relationship, and a desire to preserve patient quality of life were the most commonly cited barriers in determining medical fitness of patients to drive.

Conclusions

Legal requirements to report medically unfit drivers put physicians in the difficult position of balancing patient autonomy and public safety. More comprehensive and definitive guidelines would be helpful in assisting physicians with this public health issue.

Although primary liver cancer is rare, its incidence rate has been rising quickly in Canada, more than tripling since the early 1980s. This cancer is more common in men than women, and the age-specific incidence rates in men have been increasing significantly in all age groups from 40 years of age onward. The death rate has followed a similar upward trajectory, in part because of the low 5-year survival rate of 18% in both sexes. Infection with the hepatitis B or C virus continues to be the most common risk factor, but other factors may also play a role. Risk reduction strategies, such as viral hepatitis screening, have been recommended in other countries and warrant consideration in Canada as part of a coordinated strategy of disease prevention and control.

Gastrointestinal fistulae can occur in ovarian cancer patients, usually in the setting of advanced relapsed disease. Treatment typically involves immediate surgery.

Here, we describe a case of an abscess resulting from an intestinal fistula as the first manifestation of advanced epithelial ovarian cancer, and we review the current literature on this subject. The patient was successfully treated with a combination of chemotherapy, antibiotics, and delayed surgery. Optimal debulking was achieved without a need for bowel resection.

This report is the first of conservative management of a fistula in an ovarian cancer patient in the chemotherapy-naïve setting.

Avascular necrosis (avn) of the hip is a well-documented side effect of corticosteroid therapy, but it has also been described as a complication of radiation and chemotherapy. Many prostate cancer patients undergo treatment with all three of those therapeutic modalities, and yet reported cases of avn of the hip in prostate cancer patients are rare. Symptoms that might potentially alert physicians to this complication are nonspecific and may be attributed to cancer progression, in particular to progressive bone metastasis.

Here, we report on a 79-year-old man diagnosed with castration-resistant prostate cancer whose diagnosis of avn of the hip was confounded by his underlying malignancy. We discuss risk factors and diagnostic clues in this differential diagnosis of acute hip pain in patients with castration-resistant prostate cancer. Physicians might maintain a high index of suspicion for avn of the hip in prostate cancer patients presenting with new-onset hip pain. Surgical intervention may help to prevent the appearance of avn-associated pain and the negative impact of advanced avn on overall quality of life.

Objective

This systematic review set out to summarize the research literature describing integrative oncology programs.

Methods

Searches were conducted of 9 electronic databases, relevant journals (hand searched), and conference abstracts, and experts were contacted. Two investigators independently screened titles and abstracts for reports describing examples of programs that combine complementary and conventional cancer care. English-, French-, and German-language articles were included, with no date restriction.

From the articles located, descriptive data were extracted according to 6 concepts: description of article, description of clinic, components of care, administrative structure, process of care, and measurable outcomes used.

Results

Of the 29 programs included, most were situated in the United States (n = 12, 41%) and England (n = 10, 34%). More than half (n = 16, 55%) operate within a hospital, and 7 (24%) are community-based. Clients come through patient self-referral (n = 15, 52%) and by referral from conventional health care providers (n = 9, 31%) and from cancer agencies (n = 7, 24%). In 12 programs (41%), conventional care is provided onsite; 7 programs (24%) collaborate with conventional centres to provide integrative care. Programs are supported financially through donations (n = 10, 34%), cancer agencies or hospitals (n = 7, 24%), private foundations (n = 6, 21%), and public funds (n = 3, 10%). Nearly two thirds of the programs maintain a research (n = 18, 62%) or evaluation (n = 15, 52%) program.

Conclusions

The research literature documents a growing number of integrative oncology programs. These programs share a common vision to provide whole-person, patient-centred care, but each program is unique in terms of its structure and operational model.

Objective

Our understanding of optimum health care delivery for cancer survivors is limited by the lack of a patient-centred perspective. The objectives of the present study were to explore the views of breast and colorectal cancer survivors on their routine follow-up care, with respect to needs, preferences, and quality of follow-up, and their views on cancer specialist– compared with family physician (fp)–led follow-up care.

Methods

In Nova Scotia, Canada, 23 cancer survivors (13 breast, 10 colorectal) participated in either a focus group or a one-on-one interview. Participants were asked to reflect upon their lives as cancer survivors and on the type and quality of care and support they received during the follow-up period. Each focus group or interview was transcribed verbatim, and the transcripts were audited and subjected to a thematic analysis.

Results

Six themes were identified: My care is my responsibilityHow I receive information on follow-up careI have many care needsI want to be prepared and informedThe role of my fp in my cancer experience and follow-up careThe role of media

Survivors often characterized the post–primary treatment experience as lacking in information and preparation for follow-up and providing inadequate support to address many of the care needs prevalent in survivor populations. Despite valuing fp participation in follow-up care, many survivors continued to receive comfort and reassurance from specialist care.

Conclusions

Our findings point to the need to implement strategies that better prepare breast cancer and colorectal cancer survivors for post-treatment care and that reassure survivors of the ability of their fp to provide quality care during this period.

Most patients with gastric or gastroesophageal junction (gej) cancer are diagnosed with inoperable advanced or metastatic disease. In these cases, chemotherapy is the only treatment demonstrating survival benefit. The present study compares clinicopathologic characteristics and survival outcomes for patients with advanced esophageal, gej, and gastric adenocarcinoma treated with first-line chemotherapy [epirubicin–cisplatin–5-fluorouracil (ecf), epirubicin–cisplatin–capecitabine (ecx), or etoposide–leucovorin–5-fluorouracil (elf)] or best supportive care (bsc) at our institution with those for historical controls.

Methods

We retrospectively reviewed medical information for 401 patients with newly diagnosed advanced esophageal, gej, or gastric adenocarcinoma treated with first-line chemotherapy (ecf, ecx, or elf) or bsc from January 1, 2004, through December 31, 2010. Descriptive statistics were used to compare the data collected with data for historical control patients.

Results

Of the study patients, 93% were diagnosed with metastatic disease (n = 374), and 63% received bsc only (n = 251). The main reasons that patients received bsc only included poor Eastern Cooperative Oncology Group performance status (55%), patient decision (31%), and comorbidities (14%). Of the remaining patients, 98 (24%) received ecf or ecx and 52 (13%) received elf as first-line treatment. Median overall survival was significantly longer in patients treated with ecf or ecx or with elf than in those receiving bsc (12.7 months vs. 12.7 months vs. 5.5 months respectively). Chemotherapy also significantly reduced the risk of death (64% reduction with ecf or ecx, 58% with elf).

Conclusions

We confirmed the substantial overall survival benefit of combination chemotherapy compared with bsc, with better survival in our patient population than in historical controls. However, novel treatment options are still warranted to improve outcomes in this patient population.

Objective

To determine the toxicity and effectiveness of 24 months of adjuvant temozolomide (tmz) with cis-retinoic acid (cra) for patients with glioblastoma.

Methods

This retrospective population-based review considered the charts of all patients diagnosed with glioblastoma in Manitoba and referred to a provincial cancer centre during 2002–2008. Consecutive patients came from a population-based referral centre and provincial cancer registry.

All patients were treated according to the local standard of care with surgical resection followed by concurrent radiotherapy and tmz 75 mg/m2 daily, followed by tmz 150–200 mg/m2 for days 1–5, repeated every 28 days for up to 24 cycles, and cra 50 mg/m2 twice daily for days 1–21, repeated every 28 days.

The main outcome measures were safety, tolerability, and effectiveness of long-term tmz and cra.

Results

Of 247 patients diagnosed with glioblastoma in Manitoba during the study period, 116 started concurrent chemoradiotherapy, and 80 received adjuvant tmz. Of the patients who started concurrent chemoradiotherapy, 80 began adjuvant chemotherapy. Patients completed a median of 5.5 cycles of tmz and 3 cycles of cra. Grade 3 or 4 hematologic toxicity was noted in 16% of patients. Median overall survival was 15.1 months, and 26.7% of patients remained alive at 2 years.

Conclusions

Extended adjuvant tmz and cra is well tolerated. However, the population-based effectiveness of this regimen is similar to the clinical trial efficacy of 6 months of adjuvant tmz. Future studies in glioblastoma should incorporate duration of adjuvant chemotherapy into the study design.
