The eHealth self-management application 'Oncokompas' that supports cancer survivors to improve health-related quality of life and reduce symptoms: which groups benefit most?

BACKGROUND

Oncokompas is a web-based self-management application that supports cancer survivors to monitor their health-related quality of life (HRQOL) and symptoms, and to obtain personalised feedback and tailored options for supportive care. In a large randomised controlled trial among survivors of head and neck cancer, colorectal cancer, and breast cancer and (non-)Hodgkin lymphoma, Oncokompas proved to improve HRQOL, and to reduce several tumour-specific symptoms. Effect sizes were however small, and no effect was observed on the primary outcome patient activation. Therefore, this study aims to explore which subgroups of cancer survivors may especially benefit from Oncokompas.

MATERIALS AND METHODS

Cancer survivors (n = 625) were randomly assigned to the intervention group (access to Oncokompas, n = 320) or control group (6 months waiting list, n = 305). Outcome measures were HRQOL, tumour-specific symptoms, and patient activation. Potential moderators included socio-demographic (sex, age, marital status, education, employment), clinical (tumour type, stage, time since diagnosis, treatment modality, comorbidities), and personal factors (self-efficacy, personal control, health literacy, Internet use), and patient activation, mental adjustment to cancer, HRQOL, symptoms, and need for supportive care, measured at baseline. Linear mixed models were performed to investigate potential moderators.

RESULTS

The intervention effect on HRQOL was the largest among cancer survivors with low to moderate self-efficacy, and among those with high personal control and those with high health literacy scores. Cancer survivors with higher baseline symptom scores benefitted more on head and neck (pain in the mouth, social eating, swallowing, coughing, trismus), and colorectal cancer (weight) specific symptoms.

DISCUSSION

Oncokompas seems most effective in reducing symptoms in head and neck cancer and colorectal cancer survivors who report a higher burden of tumour-specific symptoms. Oncokompas seems most effective in improving HRQOL in cancer survivors with lower self-efficacy, and in cancer survivors with higher personal control, and higher health literacy.

Cost-utility of an eHealth application 'Oncokompas' that supports cancer survivors in self-management: results of a randomised controlled trial

Purpose

The eHealth self-management application ‘Oncokompas’ was developed to support cancer survivors in monitoring health-related quality of life (HRQOL) and symptoms, and obtaining personalized feedback and options for supportive care. The aim of this study was to assess the cost-utility of Oncokompas compared with care as usual (CAU) among cancer survivors.

Methods

Survivors were randomly allocated to the intervention or control group. Direct (non-)medical, indirect non-medical costs, and HRQOL were measured at 3- and 6-month follow-up, using iMTA Medical Consumption and Productivity Costs and the EuroQol-5D questionnaires. Mean cumulative costs and quality-adjusted life-years (QALYs) were compared between both groups.

Results

In total, 625 survivors were randomized into intervention (n = 320) or control group (n = 305). Base case analysis showed that incremental costs from a societal perspective were − €163 (95% CI, − 665 to 326), and incremental QALYs were 0.0017 (95% CI, − 0.0121 to 0.0155) in the intervention group compared with those in the control group. The probability that, compared with CAU, Oncokompas is more effective was 60%, less costly 73%, and both more effective and less costly 47%. Sensitivity analyses showed that incremental costs vary between − €40 and €69, and incremental QALYs vary between − 0.0023 and − 0.0057.

Conclusion

Oncokompas is likely to be equally effective on utilities, and not more expensive than CAU, and will therefore contribute to sustainable cancer survivorship care in a (cost-)effective manner.

Implications for Cancer Survivors

Oncokompas seems to improve HRQOL and reduces the burden of several tumour-specific symptoms, while costs from a societal perspective are similar to CAU.

Screening for head and neck second primary tumors in patients with esophageal squamous cell cancer: A systematic review and meta-analysis

Background

Esophageal squamous cell carcinomas (ESCCs) are often accompanied by head and neck second primary tumors (HNSPTs). The prognosis of patients with an additional HNSPT is worse compared with patients with only ESCC. Therefore, early detection of HNSPTs may improve the overall outcome of patients with ESCC.

 The purpose of this study was to investigate the yield of endoscopic screening for HNSPTs in patients with primary ESCC.

Methods

We conducted a systematic literature search of all available databases. Studies were included if ESCC patients were endoscopically screened for HNSPT. The primary outcome was the pooled prevalence of HNSPTs.

Results

Twelve studies, all performed in Japan, were included in this systematic review with a total of 6483 patients. The pooled prevalence of HNSPTs was 6.7% (95% confidence interval: 4.9–8.4). The overall heterogeneity was high across the studies (I²= 89.0%, p < 0.001). Most HNSPTs were low stage (85.3%) and located in the hypopharynx (60.3%). The proportion of synchronous (48.2%) and metachronous (51.8%) HNSPTs was comparable.

Conclusion

Based on our results, HNSPT screening could be considered in patients with primary ESCC. All studies were performed in Japan; it is therefore not clear whether this consideration applies to the Western world.

Discrimination between oral cancer and healthy tissue based on water content determined by Raman spectroscopy

Tumor-positive resection margins are a major problem in oral cancer surgery. High-wavenumber Raman spectroscopy is a reliable technique to determine the water content of tissues, which may contribute to differentiate between tumor and healthy tissue. The aim of this study was to examine the use of Raman spectroscopy to differentiate tumor from surrounding healthy tissue in oral squamous cell carcinoma. From 14 patients undergoing tongue resection for squamous cell carcinoma, the water content was determined at 170 locations on freshly excised tongue specimens using the Raman bands of the OH-stretching vibrations (3350-3550 cm(-1)) and of the CH-stretching vibrations (2910-2965 cm(-1)). The results were correlated with histopathological assessment of hematoxylin and eosin stained thin tissue sections obtained from the Raman measurement locations. The water content values from squamous cell carcinoma measurements were significantly higher than from surrounding healthy tissue (p-value < 0.0001). Tumor tissue could be detected with a sensitivity of 99% and a specificity of 92% using a cutoff water content value of 69%. Because the Raman measurements are fast and can be carried out on freshly excised tissue without any tissue preparation, this finding signifies an important step toward the development of an intraoperative tool for tumor resection guidance with the aim of enabling oncological radical surgery and improvement of patient outcome.

Transplantation of tracheal autografts: is a two-stage procedure necessary?

BACKGROUND

Tracheal autotransplantation has been shown to be a reliable technique for repairing the hemilaryngectomy defect that includes the hemicricoid cartilage and results from resection of unilateral laryngeal cancer with significant subglottic extension. The technique involves a two-stage procedure of cervical tracheal revascularization by wrapping the trachea in a vascularized radial forearm flap and subsequent tracheal transplantation on a newly created vascular pedicle consisting of the radial artery and vein (1, 2).

OBJECTIVES

To experimentally (rabbits) investigate if a one-stage tracheal revascularization and transplantation procedure could be a viable option.

METHODS

Tracheal patch autografts (1.5 cm x 1 cm) were excised and reimplanted at the anterior cervical trachea with four different patterns of vascular supply: group I: tracheal patch wrapped with vascularized fascia 14 days before excision of the patch (two-stage procedure); group II: tracheal patch wrapped with vascularized fascia at the time of patch excision; group III: tracheal patch without tissue wrapping; and group IV: tracheal patch wrapped with a sheet of Gore-Tex after reimplantation. After orthotopical reimplantation, the patches showed decreasing vascular contacts from group I to group IV. The patches were evaluated morphologically at the moment the animal became dyspnoeic or two weeks after reimplantation in asymptomatic animals.

RESULTS

Group I patches fully preserved their viability (median percentage mucosal viability of 100%). Autografts in group II and III showed varying degrees of necrosis and graft take with a median percentage graft viability of 59 and 69% respectively. All group IV tracheal patches showed full thickness necrosis over the majority of their surface area (median percentage graft viability of 10%).

CONCLUSION

Fascia enwrapped tracheal autografts show reliable revascularization through the intercartilaginous ligaments only when a 2 stage revascularization technique is used.

Squamous cell carcinoma of maxillary sinus

BACKGROUND

Medical records of 43 patients with histologically proved diagnosis of squamous cell carcinoma who were treated between the years 1975 and 1994 at the department of Otolaryngology Head Neck Surgery, VU Amsterdam were examined.

METHODS

Tumors were restaged according to UICC classification 1997. Thirty-eight patients were treated for cure, nine were treated with chemotherapy followed by external beam radiotherapy, and 28 patients were treated with surgery followed by postoperative radiotherapy. No patient was lost to follow-up. Data with respect to survival were analyzed.

RESULTS

Eighty-three percent of the tumours were in stage III or stage IV at the time of first presentation. Five-year survival after surgery and postoperative radiotherapy for all patients was 64%. For stages II, III, and IV it was 83%, 49%, and 37%, respectively. Cervical nodal metastases were present in 4.1% at the time of presentation. Thirty-seven percent of the patients survived 2 years after chemotherapy followed by radiotherapy.

CONCLUSIONS

Squamous cell carcinoma continues to be diagnosed late. Surgery followed by radiotherapy remains the treatment of choice. Mandibulotomy should be considered for better clearance of retromaxillary space in T3 -T4 tumors. The eye should be preserved whenever it is oncologically safe to do so.

Carcinoma of the ethmoid: results of treatment with conventional surgery and post-operative radiotherapy

AIMS

A retrospective study was carried out of 50 patients with carcinoma of the ethmoid, treated over a period of 20 years.

METHODS

The treatment used was surgery, followed by post-operative external beam radiotherapy and when possible supplemented by brachytherapy.

RESULTS

Although the nature of surgery in the majority of cases was conventional, the 63% 5-year overall survival, except in adenocarcinomas, was slightly better than that achieved by more aggressive surgery. There was no mortality and morbidity was minimal.

CONCLUSIONS

Conventional surgery in combination with radiotherapy and brachytherapy gives satisfactory and comparable results.
