ObjectiveTo investigate knowledge, attitudes, and practices of oncologists towards physical activity (PA) in cancer survivors, and the association between oncologists’ own PA behavior and PA promotion.MethodsOncologists (n = 123) completed a survey based on the Theory of Planned Behavior (TPB). Participants reported PA promotion behavior, PA involvement, attitudes, intentions, social norm, perceived behavioral control (PBC), and confidence and knowledge of exercise prescription. Structural equation modeling (SEM) evaluated these associations.ResultsLess than half of oncologists reported regularly promoting PA to patients (46%), with 20% providing written information and 23% referrals. Only 26% were physically active. TPB SEM pathways explained 54.6% of the variance in PA promotion (comparative fit index (CFI) = 0.905, standardized root mean square residual (SRMR) = 0.040). Social norm was not only the significant pathway to intention but also a significant indirect pathway to PA promotion (p = 0.007). Confidence to promote PA, PBC, and intentions were direct significant pathways to PA promotion (p < 0.05). Exploratory SEM pathways explained 19.6% of the variance of PA behavior, which in turn explained 13.1% social norm, 10.7% attitude, 10.0% confidence to recommend, and 17.8% PA promotion behavior (CFI = 0.921, SRMR = 0.076). Instrumental attitude was a direct significant pathway to PA behavior (p = 0.001). PA behavior was a direct significant pathway to social norms, attitude, confidence to recommend, and PA promotion (p < 0.05).ConclusionsOncologists reported a modest ability to promote PA, low PA promotion rates, and limited knowledge of exercise prescription. Patient physical activity promotion may be improved through strategies that increase oncologists’ PBC, confidence, and their own personal PA participation.

High-grade serous ovarian carcinoma (HGSOC) is genetically unstable and characterised by the presence of subclones with distinct genotypes. Intratumoural heterogeneity is linked to recurrence, chemotherapy resistance, and poor prognosis. Here, we use spatial transcriptomics to identify HGSOC subclones and study their association with infiltrating cell populations. Visium spatial transcriptomics reveals multiple tumour subclones with different copy number alterations present within individual tumour sections. These subclones differentially express various ligands and receptors and are predicted to differentially associate with different stromal and immune cell populations. In one sample, CosMx single molecule imaging reveals subclones differentially associating with immune cell populations, fibroblasts, and endothelial cells. Cell-to-cell communication analysis identifies subclone-specific signalling to stromal and immune cells and multiple subclone-specific autocrine loops. Our study highlights the high degree of subclonal heterogeneity in HGSOC and suggests that subclone-specific ligand and receptor expression patterns likely modulate how HGSOC cells interact with their local microenvironment. Intratumoural heterogeneity in high-grade serous ovarian carcinoma (HGSOC) remains to be explored. Here, the authors perform spatial transcriptomics and reveal a high degree of subclonal heterogeneity in HGSOC.

Each year, more than half a million women are diagnosed with cervical cancer and the disease results in over 300 000 deaths worldwide. High-risk subtypes of the human papilloma virus (HPV) are the cause of the disease in most cases. The disease is largely preventable. Approximately 90% of cervical cancers occur in low-income and middle-income countries that lack organised screening and HPV vaccination programmes. In high-income countries, cervical cancer incidence and mortality have more than halved over the past 30 years since the introduction of formal screening programmes. Treatment depends on disease extent at diagnosis and locally available resources, and might involve radical hysterectomy or chemoradiation, or a combination of both. Conservative, fertility-preserving surgical procedures have become standard of care for women with low-risk, early-stage disease. Advances in radiotherapy technology, such as intensity-modulated radiotherapy, have resulted in less treatment-related toxicity for women with locally-advanced disease. For women with metastatic or recurrent disease, the overall prognosis remains poor; nevertheless, the incorporation of the anti-VEGF agent bevacizumab has been able to extend overall survival beyond 12 months. Preliminary results of novel immunotherapeutic approaches, similarly to other solid tumours, have shown promising results so far.

Objective Fear of recurrence is common following treatment for cancer. Our aim was to assess the feasibility of mindfulness-based cognitive therapy (MBCT) to treat fear of cancer recurrence (FCR) in ovarian cancer survivors. Methods Investigator initiated, single-arm, open-label, pilot study. Women were eligible after completing adjuvant treatment. The intervention was an 8-week MBCT course of weekly 2-h group sessions. The primary outcome was FCR measured by the FCR inventory. Secondary outcomes were depression and anxiety measured by the Hospital Anxiety and Depression Scale (HADS). The study is registered with the Australian and New Zealand Clinical Trials Registry ACTRN12615000213549. Results Between May 8, 2015, and May 6, 2019, 33 participants were enrolled. Ten women withdrew. Data were evaluable for 19 participants. There was a significant decrease in FCR at 8 weeks (FCR inventory mean 63.00, SD 27.90) compared to pre-intervention (FCR inventory mean 71.03, SD 31.01) but not at 6 months (FCR inventory mean 63.65 , SD 30.08). No differences in depression were observed at baseline (HADS mean 3.42, SD 2.41), 8 weeks (HADS mean 3.10, SD 1.79) and 6 months (HADS mean 2.73, SD 1.88). Anxiety decreased from baseline (HADS mean 8.72, SD 3.99) at both 8 weeks (HADS mean 6.89, SD 2.98) and 6 months (HADS mean 7.06, SD 3.87). Conclusions MBCT may be effective as a treatment for FCR and anxiety in women following diagnosis and treatment of ovarian cancer. A randomised controlled trial is required to assess the efficacy of MBCT for FCR but may not be feasible due to high rates of withdrawal.

Background Non-invasive prenatal testing (NIPT) identifies fetal aneuploidy by sequencing cell-free DNA in the maternal plasma. Pre-symptomatic maternal malignancies have been incidentally detected during NIPT based on abnormal genomic profiles. This low coverage sequencing approach could have potential for ovarian cancer screening in the non-pregnant population. Our objective was to investigate whether plasma DNA sequencing with a clinical whole genome NIPT platform can detect early- and late-stage high-grade serous ovarian carcinomas (HGSOC). Methods This is a case control study of prospectively-collected biobank samples comprising preoperative plasma from 32 women with HGSOC (16 ‘early cancer’ (FIGO I–II) and 16 ‘advanced cancer’ (FIGO III–IV)) and 32 benign controls. Plasma DNA from cases and controls were sequenced using a commercial NIPT platform and chromosome dosage measured. Sequencing data were blindly analyzed with two methods: (1) Subchromosomal changes were called using an open source algorithm WISECONDOR (WIthin-SamplE COpy Number aberration DetectOR). Genomic gains or losses ≥ 15 Mb were prespecified as “screen positive” calls, and mapped to recurrent copy number variations reported in an ovarian cancer genome atlas. (2) Selected whole chromosome gains or losses were reported using the routine NIPT pipeline for fetal aneuploidy. Results We detected 13/32 cancer cases using the subchromosomal analysis (sensitivity 40.6 %, 95 % CI, 23.7–59.4 %), including 6/16 early and 7/16 advanced HGSOC cases. Two of 32 benign controls had subchromosomal gains ≥ 15 Mb (specificity 93.8 %, 95 % CI, 79.2–99.2 %). Twelve of the 13 true positive cancer cases exhibited specific recurrent changes reported in HGSOC tumors. The NIPT pipeline resulted in one “monosomy 18” call from the cancer group, and two “monosomy X” calls in the controls. Conclusions Low coverage plasma DNA sequencing used for prenatal testing detected 40.6 % of all HGSOC, including 38 % of early stage cases. Our findings demonstrate the potential of a high throughput sequencing platform to screen for early HGSOC in plasma based on characteristic multiple segmental chromosome gains and losses. The performance of this approach may be further improved by refining bioinformatics algorithms and targeting selected cancer copy number variations.

The study purpose was to investigate the acceptability and utility of, and preference for, wearable activity trackers (WATs) amongst cancer survivors living in regional and remote areas of Western Australia. Twenty participants were recruited (Mean age = 63 years, SD = 13) to test two to three trackers from five available models (Fitbit Alta, Garmin Vivofit 2, Garmin Vivosmart, Polar loop 2 and Polar A300). Participants wore each device for two weeks, followed by a one-week washout period between devices. Interviews were conducted with participants to explore user perceptions and experiences. Interview transcripts were analysed using thematic analysis. Four main themes emerged: (i) Consciousness raising; (ii) Prompts and Feedback; (iii) Accuracy and registry of activities; and, (iv) WAT preferences and features. WATs were acceptable and useful to cancer survivors. WATs increased self-awareness of physical activity, provided real time feedback in relation to step goals, and reinforced progress and efforts towards goals. The aesthetics of the WATs were deemed crucial in determining preference and likelihood of use. Future interventions may do well to have two different WATs available for participants to choose from, according to activity preferences, aesthetic preferences, and display size.

This volume contains a number of articles on modern Chinese history and historiography written by one of the leading academic experts on the subject. The author provides a critique of older approaches to nineteenth-century history and offers powerful reinterpretations of such key events in the recent history of China as the boxer rebellion, Mao's ascension to power in 1949, and the process of political and economic reform in the post-Mao era. This is a strong collection which will be of enormous interest to scholars of East Asian history.

As medical treatment increasingly focuses on improving health-related quality of life, patient-reported outcome measures (PROMs) are an essential component of clinical research. The National Gynae-Oncology Registry (NGOR) is an Australian clinical quality registry. A suitable PROM was required for the NGOR ovarian cancer module to complement clinical outcomes and provide insights into outcomes important to patients. Our narrative review aimed to identify existing ovarian cancer-specific PROMs and ascertain which tool would be most appropriate for implementation into the NGOR ovarian cancer module. A literature review of Cochrane Library, Embase, MEDLINE and PubMed databases was performed to identify existing ovarian cancer-specific PROM tools. A steering committee was convened to (1) determine the purpose of, and criteria for our required PROM; and (2) to review the available tools against the criteria and recommend the most appropriate one for implementation within the NGOR. The literature review yielded five tools: MOST, EORTC QLQ-OV28, FACIT-O, NFOSI-18 and QOL-OVCA. All were developed and validated for use in clinical trials, but none had been validated for use in clinical quality registry. Our expert steering committee pre-determined purpose of a PROM tool for use within the NGOR was to enable cross-service comparison and benchmarking to drive quality improvements. They identified that while there was no ideal, pre-existing, ovarian cancer-specific PROM tool for implementation into the NGOR, on the basis of its psychometric properties, its available translations, its length and its ability to be adapted, the EORTC tool is most fit-for-purpose for integration into the NGOR. This process enabled identification of the tool most appropriate to provide insights into how ovarian cancer treatments impact patients’ quality of life and permit benchmarking across health services.

Background Use of patient-reported outcome measures in clinical settings facilitate the delivery of better health care to improve patient health outcomes. Previously collected qualitative data indicated themes that could inform items for a health-related quality of life measure. This study investigated the content validity of items for inclusion in a new health-related quality of life measure suitable for patients with ovarian cancer. Methods Cognitive interviewing techniques were used with fourteen women diagnosed with ovarian cancer and at different times since diagnosis, to evaluate items derived from the previously collected qualitative dataset. A set of draft items was administered via telephone, Zoom and WhatsApp app together with questions on item meaning and wording. Interviews were transcribed and thematically analysed. Results Four broad themes emerged in relation to the questionnaire construction and comprehension of items: intent and clarity, wording, relevance and context, and overall questionnaire construct. All draft items were adjusted based on the interview findings. A final set of 38 health-related quality of life items comprised 7 items describing physical health and functioning, 21 describing emotional wellbeing and 10 items describing social wellbeing; each rated on a five-point frequency response scale. Conclusion The items reflected a range of personal experiences associated with the patient clinical journey, creating a health-related quality of life tool specific to women diagnosed with ovarian cancer. The cognitive interviewing process established content validity for the tool, thereby, preparing it for field testing and evaluation of its psychometric properties. This study highlighted the fundamental role of cognitive interviewing during health-related quality of life questionnaire development to ensure that item content is grounded in patient feelings, functioning and meaning.
